    [0001] The invention relates to the field of battery charging and swapping, and in particular to a vehicle positioning device for a battery charging and swapping station. Background Art
    [0002] With the popularization of electric vehicles, how to quickly and effectively provide electric energy replenishment for electric vehicles has become a very important issue for vehicle owners and major manufacturers. The current mainstream electric energy replenishment solutions on the market are mainly divided into charging solutions and battery swapping solutions. The charging solutions are mainly to quickly or slowly charge the electric vehicles via a charging pile (provided in a charging station or a parking space), and the battery swapping solutions are mainly to directly swap the on-board used battery for a fresh battery. Compared with the charging solutions, the battery swapping solutions can complete the electric energy replenishment of the electric vehicles in a very short time, and do not affect the service life of the traction battery, so they are one of the main development directions of electric energy replenishment. The battery swapping solutions are usually carried out in battery charging and swapping stations. A battery swap station generally comprises a battery swap platform for battery swapping of an electric vehicle, a battery compartment for storing and performing electric energy replenishment on the used battery, and a battery swap trolley for carrying the fresh/used traction battery between the battery swap platform and the battery compartment.
    [0003] When performing the battery swapping, first, the electric vehicle needs to be driven to the battery swap platform, and a vehicle positioning device on the battery swap platform is used to position a vehicle body such that the battery swap trolley can be accurately positioned with the traction battery at the bottom of the vehicle, and the traction battery is then swapped. The invention patent with the publication number CN 205997867 U discloses a vehicle tire positioning device for a battery swap station, the device comprising a bottom plate and guide columns installed on the bottom plate, a front-wheel rolling shaft assembly, a front-wheel alignment push rod, a rear-wheel rolling shaft assembly and a rear-wheel alignment push rod. The front-wheel alignment push rod and the rear-wheel alignment push rod are respectively used to push the front and rear wheels of the vehicle to move in the left and right directions, such that the vehicle can be accurately positioned in the left and right directions. Each alignment push rod comprises a push rod motor, a reduction gear box, and two couplings, two lead screws and two push plates which are symmetrically arranged. During operation, the push rod motor transmits power to the two symmetrical push plates through the reduction gear box, the couplings and the lead screws, and the two push plates then respectively push two tires from the inside thereof to complete the positioning of the vehicle. Although such a configuration can realize the precise positioning function of the vehicle, there are still certain defects in practical applications. First, due to the configuration in which a push rod motor is used to drive two push rods to push the tires from the inside to the outside, not only the push rod motor is prone to overload, affecting the service life of the motor, but also the positioning device cannot be differentially adjusted because the two push rods can only telescopically move at the same time. Secondly, since the front-wheel alignment push rod and the rear-wheel alignment push rod are both arranged in the middle of the battery swap platform, they occupy a certain amount of parking space, such that more accurate parking technology is required when the vehicle enters the battery swap platform. The difficulty in parking for a vehicle owner is increased, bringing about a bad experience of battery swapping.

    [0019] Preferred embodiments of the invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although an I-shaped roller unit only comprises a second roller in the drawings, such a configuration is not invariable, those skilled in the art can adjust same according to requirements so as to adapt to specific application scenarios. For example, the I-shaped roller unit may also be configured as a plurality of second rollers connected in series.
    [0020] It should be noted that in the description of the invention, the terms, such as "centre", "upper", "lower", "left", "right", "vertical", "horizontal", "inner" and "outer", that indicate directions or positional relationships are based on the directions or positional relationships shown in the drawings only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitation to the invention. In addition, the terms "first", "second" and "third" are for descriptive purposes only and should not be construed as indicating or implying relative importance.
    [0021] In addition, it should also be noted that, in the description of the invention, the terms "mount", "engage" and "connect" should be interpreted in a broad sense unless explicitly defined and limited otherwise, which, for example, can mean a fixed connection, a detachable connection or an integral connection; can mean a mechanical connection or an electrical connection; and can mean a direct connection, an indirect connection by means of an intermediary, or internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in the invention can be interpreted according to the specific situation.
    [0022] Referring to Figs. 1, 2 and 3, Fig. 1 is a schematic structural view of a vehicle positioning device for a battery charging and swapping station of the invention; Fig. 2 is a partial enlarged view of part A in Fig. 1; and Fig. 3 is a partial enlarged view of part B in Fig. 1.
    [0023] As shown in Fig. 1, the vehicle positioning device for a battery charging and swapping station of the invention mainly comprises a first positioning portion 2 and a second positioning portion 3 which are provided at a battery swap platform 1. The first positioning portion 2 is used to position an electric vehicle, which enters the battery swap platform 1, in a first direction, and the first positioning portion 2 also allows the electric vehicle to move in a second direction perpendicular to the first direction. The second positioning portion 3 is used to position the electric vehicle in the second direction. After the positioning of the first positioning portion 2 and the positioning of the second positioning portion 3 are completed, a battery swap robot can swap a traction battery of the electric vehicle. It should be noted that the first direction may be the driving direction when the electric vehicle enters the battery swap platform 1 (i.e., the X-axis direction in Fig. 1, the same below), and the second direction may be a width direction of the electric vehicle (i.e., the Y-axis direction in Fig. 1, the same below) perpendicular to the driving direction of the electric vehicle.
    [0024] With continued reference to Fig. 1 and in combination with Figs. 2 and 3, specifically, the first positioning portion 2 may comprise a front-wheel roller group 21 (i.e., a first roller group) and a rear-wheel roller group 22 (i.e., a second roller group). The front-wheel roller group 21 comprises a plurality of V-shaped roller units 211 (viewed in the Y-axis direction, which are V-shaped) arranged side by side in the Y-axis direction. Front wheels of the electric vehicle can be fixed in the X-axis direction in such a way that they are embedded into the V-shaped roller unit 211. After being fixed in the X-axis direction, the front wheels can also move in the Y-axis direction as the V-shaped roller units 211 roll. Referring to Fig. 2, preferably, as viewed in the Y-axis direction, the V-shaped roller unit 211 may be two first rollers 2111 arranged in a V-shape. It is conceivable to those skilled in the art that the number of V-shaped roller units 211 of the front-wheel roller group 21 and the number and arrangement of the rollers in the V-shaped roller unit 211 are not invariable, and can be adjusted according to the specific use environment while satisfying a condition that the front wheels of the electric vehicle can move in the Y-axis direction and are fixed in the X-axis direction. Referring to Fig. 3, the rear-wheel roller group 22 comprises a plurality of I-shaped roller units 221 arranged in the X-axis direction, which are arranged side by side in the Y-axis direction, and rear wheels supported on the I-shaped roller units 221 can move in the Y-axis direction. Preferably, the I-shaped roller unit 221 may be a second roller 2211 arranged horizontally. Of course, it is conceivable to those skilled in the art that the I-shaped roller unit 221 may also be configured as several rollers horizontally connected in series, etc.
    [0025] With further reference to Fig. 1 in conjunction with Figs. 2 and 3, the second positioning portion 3 comprises two front-wheel centring mechanisms 31 (i.e., first centring mechanisms) and two rear-wheel centring mechanisms 32 (i.e., second centring mechanisms). The two front-wheel centring mechanisms 31 and the two rear-wheel centring mechanisms 32 can respectively move and position the front and rear wheels of the electric vehicle in the Y-axis direction. In conjunction with Figs. 2 and 3, preferably, the two front-wheel centring mechanisms 31 are symmetrically arranged about a symmetry axis of the battery swap platform 1 (as shown by the dot-and-dash line in Fig. 1). Each front-wheel centring mechanism 31 comprises a power transmission portion provided in the middle of a battery swap bottom plate in the Y-axis direction, and a pull plate 34 extending from the power transmission portion towards one side. The power transmission portion is integrally embedded into the battery swap platform 1, and part of the pull plate 34 protrudes from the battery swap platform 1. The rear-wheel centring mechanism 32 can move in synchronization with the front-wheel centring mechanism 31. Preferably, the rear-wheel centring mechanisms 32 may adopt the same structure and arrangement as the front-wheel centring mechanisms 31, that is, the two rear-wheel centring mechanisms 32 are also symmetrically arranged, and each rear-wheel centring mechanism comprises a power transmission portion and a pull rod extending towards one side. The power transmission portions output power to the pull plates 34, and the pull plates 34 can pull the front/rear wheels from the outside to the inside of the front/rear wheels of the electric vehicle, to respectively position the front/rear wheels of the electric vehicle in the second direction, so as to position the electric vehicle in the second direction. It is conceivable to those skilled in the art that the rear-wheel centring mechanisms 32 may also take other forms, as long as the form enables the rear wheels of the electric vehicle to move in a transverse direction and finally to be fixed in the transverse direction.
    [0026] It should be noted that, in order to clearly describe the arrangement positions, a top layer of the battery swap platform 1 is omitted here. In fact, the battery swap platform 1 is divided into at least a top layer and a bottom layer. The top layer can form a plane supporting the advancement of the electric vehicle together with the front-wheel roller group 21 and the rear-wheel roller group 22.
    [0027] As shown in the orientations of Figs. 2 and 3, specifically, the power transmission portion comprises a drive motor 331, and a lead screw 332 and nut 333 unit. The drive motor 331 is preferably a servo motor, which is connected to a lead screw 332 of the lead screw 332 and nut 333 unit. The pull plate 34 is connected to a nut 333 of the lead screw 332 and nut 333 unit. In addition, the front-/rear-wheel centring mechanism 32 further comprises a guide rail 334 arranged in the Y-axis direction and a slider 335 matching the guide rail 334. The slider 335 is connected to the nut 333 for moving the pull plate 34 in the arrangement direction of the guide rail 334. In conjunction with Fig. 2, in a possible embodiment, the servo motor is connected to the lead screw 332 via a coupling, and the lead screw 332 passes below the front-wheel roller group 21. A mounting frame 35 is provided between the pull plate 34 and the nut 333, and the pull plate 34 is connected to the nut 333 via the mounting frame 35. Parallel guide rails 334 and sliders 335 matching therewith are provided on two sides of a part of the lead screw 332 away from the motor. The middle of each of the sliders 335 is fixedly connected to the nut 333, and two ends of the slider 335 are slidably connected to the parallel guide rail 334, restricting the movement of the pull plate 34 along the direction of the parallel guide rail 334, which movement enables the pull plate 34 to pass right through the middle of the front-wheel roller group 21. In conjunction with Fig. 3, in another possible embodiment, the servo motor is connected to the lead screw 332 via a coupling, and the lead screw 332 passes below one side of the rear-wheel roller group 22. Parallel guide rails 334 and sliders 335 matching therewith are provided on two sides of a part of the lead screw 332 away from the motor. The middle of each of the sliders 335 is fixedly connected to the nut 333, and two ends of the slider 335 are slidably connected to the parallel guide rail 334. A mounting frame 35 is provided between the pull plate 34 and the sliders 335, and the pull plate 34 is fixedly connected to the sliders 335 via the mounting frame 35. The pull plate 34 moves along the direction of the parallel guide rail 334 under the restriction of the sliders 335, and this movement enables the pull plate 34 to pass right above the rear-wheel roller group 22.
    [0028] It can be seen from the above description that through the provision of the two front-wheel centring mechanisms 31 and the two rear-wheel centring mechanisms 32, the invention can achieve the positioning by pulling the wheels from the outside to the inside of the wheels. The advantages of this positioning method are that on the one hand, unilateral differential adjustment of the movement of the electric vehicle can be achieved, for example the positioning accuracy of the electric vehicle and the battery swap robot is increased by means of unilateral fine-adjustment, thereby ensuring the success rate and accuracy of battery swapping. On the other hand, the configuration in which each front-/rear-wheel centring mechanism 32 is equipped with a power transmission portion also greatly reduces the load of the servo motor, thereby preventing the occurrence of overload of the servo motor. In addition, the use of the arrangement in which the power transmission portions are provided in the middle of the battery swap platform 1, the pull plates 34 are provided on two sides, and the power transmission portions are embedded into the battery swap platform 1 also effectively reduces the footprint of the front-/rear-wheel centring mechanisms 32 on the battery swap platform 1, and reduces the difficulty in parking.
    [0029] It can be understood that although the above preferred arrangement of the front-wheel centring mechanisms 31 and the rear-wheel centring mechanisms 32 is that they are embedded into the battery swap platform 1 in a symmetrical manner, this arrangement is only used to illustrate the principles of the invention and not intended to limit the scope of protection of the invention. Those skilled in the art can adjust this arrangement without departing from the principles of the invention, so as to adapt same to more specific application scenarios. As an example, it is also possible to change the two servo motors from being placed along the Y axis into being placed side by side along the X axis, and each servo motor is connected to the lead screw 332 via a pair of bevel gears. Alternatively, the two servo motors are placed one behind the other along the symmetry axis in Fig. 1, and the positions of the lead screws 332 and the pull plates 34 are correspondingly adjusted, such that the two pull plates 34 can still be arranged symmetrically. As another example, it is also possible to use pneumatic cylinders or electric cylinders to replace the servo motors to complete the output of driving forces, and to arrange the front-wheel centring mechanisms 31 and/or the rear-wheel centring mechanisms 32 on the top layer or any other position of the battery swap platform 1, as long as the condition that the wheels are pulled from the outside to the inside of the wheels can be satisfied.
    [0030] In conjunction with Fig. 1, in a possible embodiment, the positioning process of the vehicle positioning device for a battery charging and swapping station of the invention may be as follows.
    [0031] The electric vehicle is driven to the battery swap platform 1, powered off and shifted into neutral, the front wheels of the vehicle enter the V-shaped front-wheel roller group 21 and are fixed, in an embedded manner, in the front-wheel roller group 21 in the driving direction; and the rear wheels of the electric vehicle are supported on the I-shaped rear-wheel roller group 22, at which case the vehicle completes positioning in the X-axis direction. The two front-wheel centring mechanisms 31 and the two rear-wheel centring mechanisms 32 simultaneously move the pull plates 34 from the outside to the inside of the wheels. The pull plate 34 that first comes into contact with a wheel of the electric vehicle pulls the wheel to move transversely on the front-wheel roller group 21 and/or the rear-wheel roller group 22. When the four pull plates 34 are all in contact with the wheels, the electric vehicle completes the preliminary positioning in the Y-axis direction and is fixed by the pulling rods. The current positional deviation is obtained, and a single centring mechanism is used to fine-adjust the vehicle body. After the adjustment is completed, the positioning of the electric vehicle is completed, and the subsequent battery swapping operation can be performed.
    [0032] Finally, it should be noted that although this embodiment is described by taking the first centring mechanisms as the front-wheel centring mechanisms 31 and the second centring mechanisms as the rear-wheel centring mechanisms 32, this is not intended to limit the scope of protection of the invention. Those skilled in the art can also adjust the above correspondence relationship without departing from the principles of the invention, so as to adapt to more specific application scenarios. For example, the first centring mechanisms are the rear-wheel centring mechanisms 32, and the second centring mechanisms are the front-wheel centring mechanisms 31. Similarly, the correspondence relationships of the first roller group and the second roller group with the front-wheel roller group 21 and the rear-wheel roller group 22 can also be interchanged.
    [0033] Heretofore, the technical solutions of the invention have been described with reference to the preferred embodiments shown in the accompanying drawings; however, those skilled in the art can readily understand that the scope of protection of the invention is obviously not limited to these particular embodiments. Without departing from the principle of the invention, those skilled in the art may make equivalent changes or substitutions on related technical features, and the technical solutions after these changes or substitutions fall into the scope of protection of the invention.
