专利说明:

The present application claims priority to Chinese Patent Application No. 201510336485.6 entitled "LATERAL CURRENT COLLECTOR AND ELECTRIC VEHICLE" filed with the Chinese Intellectual Property Office on Jun. 16, 2015, the entire disclosure of which is hereby incorporated by reference herein becomes.
TECHNICAL AREA
The present application relates to the technical field of current collection for fast charging, and more particularly relates to a current collector for a fast-charging electric vehicle, such as an energy-storing trolleybus. The present application further relates to an electric vehicle with such a pantograph.
BACKGROUND
As part of the further development of our company, development concepts such as energy storage and environmental protection are being continuously promoted for track-bound city traffic. In this way, an energy-saving trolleybus was created. In the so-called power-storing trolleybus, a supercapacitor is used for storing electric power, and the electric power is used as drive power used for moving the trolleybus. A rooftop pantograph is used for current collection and backflow. Charging is fast within a ten-second period while passengers board or disembark at a stop and the energy-storing trolleybus can travel to the next stop with a single charge, where it is recharged. Because of the above-described characteristics, this type of vehicle is widely used.
We turn to Figures 1 and 2. Figure 1 is a schematic view showing the structure of a current collector of a charging system of a conventional power-storing trolleybus, and Figure 2 is a side view of the structure of Figure 1.
As shown in the figures, the overall mechanism of the current collector of the charging system of the conventional power line trolley bus can be thought of as a four-link mechanism mounted in a longitudinal direction of the vehicle, and a trolley line 1 'is directly above a current collector 2' (FIG. or a pantograph). Since each rod in the four-link mechanism has a fixed length and the lengths of all the rods are set proportionally, a power take-off head 3 'of the current collector 2' can be raised in an appropriately vertical direction under a spring or lift cylinder driving force. After lifting it vertically to a certain height, the power take-off head 3 'of the current collector 2' comes in contact with the overhead line 1 'directly above the current collector 2' so that current for the vehicle is tapped.
The pantograph has substantially the same operating principle as a roof-mounted pantograph (or pantograph) of other track-bound transport vehicles, non-lane transport vehicles and the like and is suitable for a track-bound transport vehicle. However, when the current collector is applied to a non-lane transport vehicle such as an overhead trolley bus, the following disadvantages arise.
Firstly, a modern energy-storing trolleybus travels on conventional rubber wheels and is not guided by rails, so that the trolleybus can remain with great deviation. However, the pantograph can only compensate for a deviation from the lateral stopping position of about 200 mm, so that high demands are placed on the skill of the driver or conductor; that is, there are high demands on a stop position and a stop angle when the trolleybus stops again and again to charge. Therefore, the requirements for practical use are difficult to meet; the operation of the trolleybus is cumbersome; and the charging process of the trolleybus is not stable.
Second, because the trolley bus is supplied with power in such a manner that the pantograph is lifted and comes into contact with the overhead line directly above the pantograph, when the trolleybus stops, the body can be vibrated when passengers off and on enter, whereby the pantograph, which is mounted on the roof of the vehicle, can also resonate. Thus, the power take-off head may rub against the pantograph to the right or left along the catenary, thereby increasing contact resistance and impairing current drain.
Third, in order for the power take-off head to really come in contact with the overhead line after it has been lifted, the power take-off head is generally constructed in the form of a long sliding plate. However, an excessively long power take-off head can lead to an unstable structure.
Fourth, the pantograph may take up much space above the trolleybus after it has been lowered, which may affect the placement of other devices, such as an emergency exit on the roof.
Therefore, the skilled person must solve the problem that the pantograph allows a greater deviation of the stop position, so that the vehicle operation is simplified and the stability of the current collection is improved.
BRIEF SUMMARY OF THE INVENTION
An object of the present application is to provide a lateral current collector. The pantograph allows a large deviation of the parking position, facilitates the vehicle operation and ensures a stable power take-off even in the event that the body of the vehicle fluctuates. In addition, the pantograph has the advantages that it has a stable structure and requires little space.
Another object of the present application is to provide a
Electric vehicle with such a pantograph.
In order to achieve the first object, there is provided a lateral current collector according to the present application including: a four-link mechanism having a base, an upper pole, a lower pole, and a tie rod; and a power take-off head disposed at an extension end of the upper bar. The four-link mechanism drives the power take-off head to make a vertical lift stroke and a lateral travel lift. In the vertical lift stroke, the pull rod remains at an unchanged length, and in the lateral travel stroke, the pull rod has a degree of telescopic freedom, and a current take-off portion of the current collection head is located on an outer side of the current collection head in a lateral movement direction.
Preferably, the drawbar is a telescopic drawbar or elastic drawbar and has a fixed end hinged to the base and a telescopic end hinged to the upper bar.

Preferably, the pull rod is provided with a telescopic control mechanism.
Preferably, the telescopic control mechanism releases the pull rod when the movement of the current collection head is changed from a vertical lift direction to a lateral outward direction, whereby the pull rod can be extended or retracted, and the telescopic control mechanism locks the pull rod when movement of the power take off head is lateral Inverted direction is changed in a vertical lowering direction, whereby the pull rod can be kept in an unchanged length.
Preferably, the telescopic control mechanism includes: a fixed sheave disposed at a lower end of the pull rod; a fixed pulley group disposed on a rotary shaft at a lower end of the lower bar; a movable pulley group mounted on the base via a movable mechanism; a steel cable which passes around the fixed pulley and then alternately around the fixed pulley group and the movable pulley group, one end of the steel cord having a hinged end where the pull rod is hinged to the upper rod or a telescopic end of the pull rod is connected and the other end is connected to the base; and a cam fixed to the rotary shaft at the lower end of the lower rod coaxial with the rotary shaft, the cam supporting the movable pulley group and driving the movable pulley group to tighten or loosen the steel cord when the cam is rotated.
Preferably, a driven sheave on one side of the movable sheave group is arranged coaxially with the movable sheave group, and the cam abuts against the driven sheave.
Preferably, a buffer spring between the movable pulley group and the base is arranged.
Preferably, the movable pulley group is pivotally mounted to the base via a pivot frame.
Preferably, a plurality of electrodes of the power take-off head are distributed in parallel with each other at intervals in a vertical direction on an outside of the power take-off head.
In order to accomplish the second object described above, there is provided an electric vehicle including a body, an electric drive system, and a charging system equipped with a current collector. The current collector is a lateral current collector according to one of the aspects described above, and the lateral current collector is mounted on the roof of the vehicle and perpendicular to the longitudinal direction of the body.
In the present application, the pull rod in the four-limbed rod mechanism of the current collector is constructed as a telescopic structure, and the current collecting part of the current collecting head is disposed on an outer side surface of the current collecting head, so that a lateral current collector is formed, which performs a current decrease in a lateral position. During operation, a catenary is mounted in the lateral position of the pantograph, and the movement of the pantograph head is a variable tracking motion that can be subdivided by a change in length of the tie rod during movement into a vertical movement and a lateral movement. The pantograph is raised vertically to a certain height (> 1500 mm) and, in conjunction with the longitudinal freedom limiting mechanism, can then move outward and horizontal by a certain distance (> 600 mm) until the power take-off head comes into contact with the overhead contact line and one Current collection is performed. The drawbar is maintained at an unchanged length during a vertical lift of the current collection head, and the drawbar is extended approximately linearly in a horizontal motion process of the power take off head. Since the current collecting head of the pantograph has a horizontal movement function over a long distance, the allowable parking position deviation may be larger, which facilitates the operation of the vehicle, improves the stability of the power take-off, and is particularly applicable to a modern power-saving trolleybus.
The electric vehicle according to the present application is provided with the lateral current collector described above, and since the lateral current collector realizes the technical effects described above, the electric vehicle equipped with the lateral current collector should also realize the respective technical effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS
In order that those skilled in the art may better understand the solution of the present application, the present application will be described in detail with reference to the drawings and embodiments.
Terms such as upper, lower, inner and outer are herein determined based on the positional relationships shown in the drawings. Depending on the drawings, the corresponding positional relationships can be changed accordingly. Therefore, these terms should not be construed as absolute limitations on the scope of the present application.
We turn to Figures 3 and 4. FIG. 3 is a diagram of a lateral current collector according to the present application; and Fig. 4 is a schematic view showing the structure of an embodiment of the lateral current collector according to the present application.
In a concrete embodiment, the lateral current collector according to the present application mainly comprises a base 1, an upper bar 2, a lower bar 3, a tie rod 4 and a current collecting head 5 and the like. The base 1, the upper bar 2, the lower bar 3 and the pull rod 4 form a four-link mechanism that can move the power take-off head 5. The lower bar 3 has a lower end which is hinged to the base 1 via a rotary shaft and an upper end which is hinged to the upper bar 2. The tie rod 4 has a lower end which is hinged to the base 1, and an upper end which is hinged to a crank arm at a rear end of the upper rod 2. The upper rod 2 is formed as a "V" shaped frame structure in which an outward end of the upper rod 2 is narrow and another end of the upper rod 2 is wide, and therefore the upper rod 2 also referred to as an upper frame becomes.
The pull rod 4 is a telescopic pull rod and in this embodiment operates with an air cylinder that exerts a preload pressure. A lower end of a cylinder body of the air cylinder is hinged to the base 1, and an upper end of a piston rod of the air cylinder is hinged to the upper rod 2. The power take-off head 5 is mounted at the outward end of the upper rod 2 via a universal bearing. A current collecting part of the current collecting head 5 is located on an outer side of the current collecting head 5 in a lateral moving direction, and a plurality of electrodes of the current collecting head 5 are distributed in parallel with each other at intervals in a vertical direction on an outer side surface of the current collecting head 5.
Turning to Figure 5, which is a partially enlarged view of a fixed pulley assembly and a movable pulley assembly of Figure 4.
The pull rod 4 is provided with a telescopic control mechanism so that the pull rod 4 can be released to be telescoped when the movement of the current collection head 5 is changed from a vertical lift to a lateral outward movement, and the pull rod 4 is locked when the Movement of the current collection head 5 is changed from a lateral inward direction to a vertical lowering direction, whereby the length of the drawbar 4 can remain unchanged.
In particular, the telescopic control mechanism mainly includes one
Steel cable 6, a fixed pulley 7, a fixed pulley group 8, a movable pulley group 9, a cam 10, etc. The fixed pulley 7 is mounted near a lower end of the pull rod 4. The fixed pulley group 8 is mounted on a rotary shaft at a lower end of the lower rod 3. The movable pulley group 9 is mounted on the base 1 via a "Y" swing frame 11, and a lower end of the swing frame 11 is hinged to the base 1. The movable pulley group 9 is located in a recess at the upper end of the swing frame 11. The steel cord 6 is connected at one end to an outer side of a propeller shaft of the upper rod 2 and the tie rod 4 and is connected to the base 1 at the other end; and the steel cord 6 extends around the fixed sheave 7 and then passes around the fixed sheave group 8 and the movable sheave group 9 alternately. The steel cord 6 above the fixed sheave 7 is arranged parallel to the tie rod 4 to ensure that a tensile force of the steel cord acts in the same direction as a pulling direction of the tie rod and the load is applied more evenly.
The cam 10 is configured to adjust a position of the movable pulley group 9 via a cam surface as the cam 10 rotates, and is fixed to a rotating shaft 12 at the lower end of the lower rod 3 coaxially with the rotating shaft 12. A driven pulley 13 is disposed coaxially with the movable pulley group 9 on one side of the movable pulley group 9. The cam 10 abuts on the driven pulley 13, and the driven pulley 13 of the movable pulley group 9 is supported on the cam 10. The cam 10 may drive the movable pulley group 9 to tighten or loosen the steel cord 6 when the cam 10 rotates together with the rotation shaft 12.
The driven pulley 13 is used to avoid dry friction when the cam 10 moves the movable pulley group 9. It is also possible that the cam 10 directly moves the movable pulley group 9, if no driven sheave 13 is present.
After the cam 10 has released the steel cable 6, the steel cable 6 is released immediately. To prevent a hard blow by the steel cable 6 is a
Buffer spring 14 disposed between one side of the movable pulley group 9 and the base 1.
Turning to FIG. 6, which is a reference view of the lateral current collector shown in FIG. 4 during use.
As shown in Fig. 6, in practice, a power supply device is mounted on a charging station (generally a bus stop). A catenary 15 of the power supply device is mounted vertically on one side above a vehicle. A plurality of catenaries 15 are distributed in parallel to each other at intervals in a vertical direction, and an arrangement of the plurality of catenaries 15 coincides with an arrangement of electrodes of the current collecting head 5. A length of each of the overhead wires 15 is larger than a length of each of the electrodes of the power take-off head 5, whereby the power take-off head 5 can come into contact with the overhead wires 15 in a large front and rear area when the vehicle reaches the stop. A width of each of the overhead wires 15 may be slightly larger than a width of each of the electrodes of the power take-off head 5 to improve the stability of the current take-off. A guide plate 16 (or a guide rail) is mounted horizontally above the catenary 15 so as to be perpendicular to the plane in which the catenary is located. The guide plate 16 (or the guide rail) is configured to limit a vertical degree of freedom of the power take-off head 5 after the power take-off head 5 has been raised to a certain height and to move the power take-off head 5 laterally and outwardly instead of upwardly. More specifically, the guide plate 16 may be a flat steel plate and the like. The lateral pantograph is mounted on the roof of the vehicle and perpendicular to the longitudinal direction of the body 17, and a lift plane of the four-link mechanism and a lateral movement direction of the power take-off head are both perpendicular to the longitudinal direction of the body 17.
When the vehicle reaches a stop and the pantograph head 5 of the pantograph needs to come into contact with the catenary 15, the pivot shaft 12 is rotated by a combined action of an air cylinder 18 and a spring 19. Since a convex part of the cam 10 abuts on the driven pulley 13 of the movable pulley group 9, the movable pulley group 9 does not move, and the length of the steel cord 6 remains unchanged when the rotating shaft 12 is first set within a certain angle (for example, 0 degrees to 30 degrees), and there is always an air pressure in the air cylinder of the pull rod 4; a tensile force applied to the air cylinder by the steel cable 6 is greater than the pressure in the cylinder; and the air cylinder is kept at an unchanged length. The power take-off head 5 is raised approximately vertically in a vertical plane perpendicular to the longitudinal direction of the body.
The power take-off head 5 is raised to a height of about 1500 mm and then abuts on an underside of the guide plate 16 via an anti-friction roller at the upper end of the power take-off head 5. In this case, the cam 10 is driven by the rotation shaft 12, and an angle by which the cam 10 is rotated is larger than 30 degrees, and a non-convex part of the cam 10 starts from the driven pulley 13 of the movable pulley group 9 to rest. With a tensile force of the steel cable 6, the movable pulley group 9 pivots together with the swing frame 11 in the direction of the fixed pulley group, so that the steel cable 6 is released. Since the steel cord 6 is released, the tensile force applied by the steel cord 6 to the air cylinder is canceled. The air cylinder is extended linearly under the effect of the air pressure, whereby the function of a telescopic pull rod is achieved. In this case, the power take-off head 5 is not further raised because it is limited by the guide plate 16, and the pull rod 4 automatically changes its length. The power take-off head 5 can move outwardly and laterally by 0 mm to 700 mm in a vertical plane perpendicular to the longitudinal direction of the body of the trolleybus until it comes into contact with the overhead line 15 of the power supply device for the purpose of power take-off. After the loading is completed, the pantograph can be returned to a collapsed state by performing the reverse operation. In the process of returning the pantograph, the preloading pressure in the air cylinder allows the drawbar to automatically retract when the power take-off head 5 is lowered.
The steel cord is wound back and forth in several windings around the fixed pulley group 8 and the movable pulley group 9, and according to the principle of lift reinforcement of a movable pulley, a gain of the movable pulley is related to the number of fixed pulleys and movable pulleys. When the gain is N, the steel cord can be released by a length of LxN after the movable sheave group 9 has moved a distance from L to the fixed sheave group 8. Therefore, in the case that the movable pulley group 9 is slightly moved, the steel cord can be released or retracted by a sufficient length. In this way, the requirement of extension and retraction of the tie rod 4 is met.
Of course, instead of being mounted to the base 1 by means of the swing frame 11, the movable sheave group 9 can also be mounted on the base 1 by means of another movement mechanism, such as by means of a straight line movement mechanism. For example, two ends of the movable pulley group 9 are mounted on slide rails so that the movable pulley group 9 can move on the slide rails under the action of the cam 10 and the tensile force of the steel cord 6, and the functions of loosening and retracting the steel cord 6 can also will be realized. That is, the movable pulley group 9 can be mounted in any manner as long as the movable pulley group 9 can move away from the fixed pulley group 8 and move close to it.
In addition to the air cylinder, the drawbar 4 may instead have another shape, such as an elastic drawbar. More specifically, the elastic tie rod can be formed by a solid tie rod and a spring which abut each other. The massive drawbar is located at a lower end and is hinged to the base. The spring is located at an upper end and is hinged to the upper rod. The specification of the spring may be determined according to a force exerted by the tie rod while the current collection head is raised so that the spring has an unchanged length in a vertical lift stroke, and the spring may expand in a lateral travel stroke contract. In this
Method, a node where the spring can expand or contract, mainly adjusted by force calculation, so that it is not necessary to provide the pull rod with a telescopic control mechanism. This is a simple embodiment of the present application.
In another form, the tie rod 4 may consist of two rod sections which are combined by a telescopic structure. A spring is placed between the two rod sections, and a preload pressure is exerted by the spring, which can also perform a similar function as the drawbar provided with an air cylinder. For the drawbar to be provided with the telescopic control mechanism, the telescopic control mechanism of the drawbar may still have the following shapes in addition to the above-described form of the steel cable-pulley cam structure.
One control method is electrification control. The telescopic function of the drawbar provided with the air cylinder can be locked or released by inserting or withdrawing a lock pin between the air cylinder body and the piston rod, and the lock pin is controlled by a small motor, an air cylinder, or an electromagnetic mechanism. In order to realize an action timing of the lock pin, an angle sensor or a stroke switch may be mounted on the four-link mechanism. When the power take-off head 5 is raised to a certain level, the angle sensor outputs an angle signal to control the movement of the lock pin or a bar of the four-link mechanism triggers the lift switch to further control the movement of the lock pin.
Another control method is a mechanical control. Since the relative positions between the bars in a lifting process are constantly changing, the telescopic timing of the tie rod 4 can be performed by changing an angle of the upper bar relative to the tie rod 4.
For example, in this implementation, the telescopic function of the drawbar provided with the air cylinder is also locked or released by inserting or withdrawing a lock pin between the air cylinder body and the piston rod. In contrast to the electrification control, in the mechanical control mode, the upper rod 2 is provided with a trigger block or trigger plate which directly interacts with the detent pin or is connected to the detent pin via a power transmission mechanism. When the power take-off head 5 is raised to a certain height, the trigger block or actuator plate may drive a pin shaft directly or via the power transmission mechanism to perform an outward movement to release the air cylinder and piston rod; and when the power take-off head 5 needs to be lowered, the trigger block or actuator plate may in turn drive the pin shaft directly or via the power transmission mechanism to make an inward movement to re-lock the air cylinder and piston rod.
The above-described embodiments are merely some preferred embodiments of the present application, and the present application is not limited thereto. On this basis, it is possible to make a targeted adjustment according to the practical requirements to obtain various embodiments. For example, in the above-described embodiments, rotation of the rotary shaft during rotation of the current collector is used as a drive for causing extension and retraction of the pull rod. But moreover, the extension and retraction movement of the pull rod can also be achieved by a motor (for controlling a worm drive, a screw shaft, a gear and the like), an air cylinder and the like. Since there are many possible implementations, these implementations are not detailed here.
In addition to the lateral pantograph, an electric vehicle is also provided according to the present application. The electric vehicle includes a body, an electric drive system and a charging system equipped with a current collector, and the current collector is the lateral current collector described above. The lateral pantograph is mounted on the roof of the vehicle and perpendicular to the longitudinal direction of the body. That is, a lift plane of the four-link mechanism and the lateral movement direction of the power take-off head are both perpendicular to the longitudinal direction of the body. Other structures may be based on conventional technology and are not described herein.
The lateral pantograph and the electric vehicle according to the present application have been described in detail above. The principle and the embodiments of the present application have been illustrated herein by means of concrete examples. The above description of examples is only intended to help understand the nature of the present application. It should be noted that those skilled in the art can make a number of modifications and improvements to the present application without departing from the principle of the present application; and these modifications and improvements are also considered to fall within the scope of the present application as defined by the claims.
