1/12 “CLOSING SYSTEM FOR A FUEL TANK DOOR”
Description [001] The present patent application for industrial invention relates to a closing system for a vehicle's fuel tank door.
[002] As is known, vehicles have a fuel port module that is attached to the vehicle body in order to define an opening to access the fuel tank. The opening of the module is closed by a door that is hinged to the module. A locking system is provided to close and open the door. This locking system generally comprises a “push-push” lock that is suitable for alternately and automatically squeezing and releasing and releasing the door whenever the door is pressed manually.
[003] This type of “push-push” lock comprises locks that are activated by an electric actuator. The lock prevents free opening of the door when the actuator is in a closed condition. Normally, the actuator is automatically activated whenever the centralized closing of the vehicle doors is activated.
[004] There are three different models of closing systems.
[005] The first model comprises a lock and a lock mounted separately on the module. The lock has a pin that holds the door and a roller that cooperates with a cam provided on the inside of the door. The latch is attached to a slot provided on the door. The fuel port module is only supplied with the lock in assembled condition. Therefore, the assembly of this first model of closing system in the vehicle body requires two different fixing operations: the first operation is dedicated to fixing the locking set and the actuator on the module, while the second operation is dedicated to fixing the module the vehicle body.
[006] The second model of closing system comprises a lock comprising a set of lock and actuator. In this case, the lock interferes with the lock pin in order to block the lock pin. In any case, the door is provided with the cam that cooperates with the roller provided in the lock. In such a case, the lock is provided separately from the module and, therefore, the assembly of this second model of
Petition 870170079138, of 10/17/2017, p. 23/45
2/12 closing the vehicle body still requires two different fastening operations: the first operation is dedicated to fixing the lock to the module, while the second operation is dedicated to fixing the module to the vehicle body.
[007] In order to reduce the time and cost of assembly of the closing system, a third model of closing system has recently been proposed that comprises a blocking assembly applied directly outside the module so that the closing system can be mounted with only one fixing operation, that is, fixing the module that acts as support for both the door and the locking set.
[008] It must be considered that the module must be mounted inside the vehicle body, inserting it from the outside to the inside through a hole in the vehicle body. This operation of installing the module is hampered by the presence of the inconvenient blocking assembly that is applied directly to the outside of the module. Obviously, car manufacturers are not willing to drill holes with different dimensions in the body of the vehicle according to the type of closing system to be installed. Therefore, to facilitate the assembly of this third type of closing system, the diameter of the module is considerably reduced, in order to compensate for the volume of the blocking set applied on the external wall of the module.
[009] The reduction in the internal diameter of the module is hindered by some disadvantages, such as the uncomfortable and incomplete introduction of a fuel pump in the tank and the difficulty of complying with the dimensional norms imposed by the applicable legislation.
[0010] WO2016 / 098851 describes a device for opening and closing a vehicle fuel door that comprises a push-push lock that is suitable for holding and releasing the door each time the door is pressed. .
[0011] The objective of the present invention is to eliminate the disadvantages of the prior art, providing a closing system that, despite being provided with a locking set applied to the external wall of the module, does not require reduction of the module, which can have a diameter substantially identical to the models of closing systems in which the locking assembly is not applied to the external wall of the module.
[0012] Another objective of the present invention is to disclose a system of
Petition 870170079138, of 10/17/2017, p. 24/45
3/12 closing with locking set with reduced size and volume that is suitable to mount the module quickly and easily on the vehicle body.
[0013] Another purpose of the invention is to disclose a locking system provided with a "push-push" locking set that can be applied on the external wall of the module, on the opposite side in relation to the side on which the door is hinged .
[0014] These objectives are achieved, according to the invention, with the characteristics of independent claim 1.

[0016] The closure system of the invention comprises:
[0017] - a module with a tubular structure with a suitable channel to communicate with a vehicle's fuel tank, [0018] - a door hinged to the module body with a hinge, in order to close the channel; said door is provided with a pin that protrudes towards the channel of the module, and [0019] - a lock mounted on the body of the module, outside the duct.
[0020] The block comprises:
[0021] - a box comprising a housing and a cover, [0022] - a closing pin suitable for securing said cover pin; said closing pin being mounted in translation mode in said box in order to slide along an axis to go from a retracted closing position to an extracted opening position, [0023] - a spring that tension the closing pin towards the extracted opening position, [0024] - a cam obtained in the said closing pin, [0025] - a roller rotatable mounted in the said housing in order to rotate freely around an axis and having a tip that acts in said closing pin cam to control the translation movement of the closing pin, [0026] - a lock comprising a slide mounted in the translation mode in the housing in such a way as to slide along an axis orthogonal to the sliding axis lock pin to move from a retracted unlock position to an advanced lock position where

5/12 emergency; and [0042] Fig. 13 is the same view as Fig. 11, in which an emergency device hook is omitted.
[0043] With reference to the Figures, the closure system of the invention is described which is generally indicated with the reference number 100.
[0044] With reference to Figs. 1 - 3, the closure system (100) comprises a module (101) that has a tubular body (102) that defines a channel (103) suitable for communicating with a vehicle fuel tank.
[0045] An annular flange (104) protrudes externally to the structure (102) of the module and is fixed to a part of the vehicle body.
[0046] A door (105) is hinged to the body (102) with a hinge (106) in order to close the channel (103) defined by the module structure. A spring (107) is applied to the hinge (106) to keep the door (105) in the open position.
[0047] A pin (110) rises from the door towards the interior of the channel (103) of the module. The pin (110) is arranged in a position diametrically opposite to the hinge (106). The pin (110) is shaped like a mushroom and comprises a stem (111) and a truncated conical head (112) that defines an annular stop surface (113).
[0048] A lock (C) is fixed to the structure (102) of the module, outside the channel (103), in a diametrically opposite position in relation to the hinge (106). An opening (120) is provided in the module frame (102) in correspondence with the lock (C) to cause the lock (C) to cooperate with the pin (110) of the door.
[0049] With reference to Figs. 4 and 5, the lock (C) comprises:
[0050] - a closing pin (2) suitable for engaging with the door pin (110), [0051] - a lock (6) suitable for locking the closing pin (2) in the closed position and [0052] - an actuator (5) suitable to actuate the lock (6).
[0053] The closing pin (2) has a cam (3) and the lock comprises a roller (I) that acts on the cam (3) in such a way that the closing pin can make the conversions that are typical of a lock like
Petition 870170079138, of 10/17/2017, p. 27/45
6/12 “push-push”.
[0054] The lock (C) comprises an emergency mechanism (E) suitable for unlocking the lock (6) when the lock (6) is in the closed position and the actuator (5) does not work.
[0055] Optionally, the lock (C) can comprise a switch (4) suitable for detecting the position of the closing pin (2).
[0056] The lock comprises a box (1) comprising a housing (10) and a cover (11). An electrical connector (16) is mounted on the cover (11), being provided with electrical contacts that pass through the cover (11) in order to be connected to the electrical parts of the lock.
[0057] A housing (12) is obtained in the housing (10) and is suitable for receiving all parts of the lock. A cylindrical cable (13) protrudes in the upper position of the housing (10) and is provided with an axial channel in communication with the housing (12) of the housing. The projections (14) project radially outwardly from the cylindrical cable (13) of the housing. With reference to Fig. 4, the projections (14) of the cylindrical cable of the housing are engaged in bayonet coupling mode inside a housing (122) obtained in a cable (121) connected to the module structure under the opening (120) of the module structure.
[0058] With reference to Figs. 5 and 5A, the closing pin (2) has a cylindrical body (20) suitable to be slidably mounted on the cable (13) of the housing in such a way that the closing pin (2) can move along a axis (Y) from a retracted closing position to an extracted opening position.
[0059] A flange (21) in the form of a rectangular plate protrudes in a lower position from the cylindrical body (20) of the closing pin. The cam (3) is obtained on the flange (21).
[0060] An annular housing (22) that houses a joint (23) is obtained in the cylindrical body (20) of the closing pin.
[0061] A plurality of elastic flanks (24) protrude in the upper position from the cylindrical body (28) of the closing pin to form a cylindrical housing (28). The elastic flanks (24) are separated by longitudinal grooves (27). Each elastic flank (24) comprises an external tooth (25) which protrudes externally and an internal tooth (26) which protrudes internally.
[0062] With reference to Fig. 4, when the head (112) of the door pin is
Petition 870170079138, of 10/17/2017, p. 28/45
7/12 inserted in the cylindrical housing (28) of the closing pin, the elastic flanks (24) bend elasticly outward and return elasticly inward, such that the inner teeth (26) of the elastic flanks are stopped against stop surface (113) of the door pin.
[0063] The cable (121) of the module has a collar (123) that protrudes inwards. When the closing pin (2) is in the retracted closing position, the collar (123) of the module cable is stopped against the elastic flanks (24) of the closing pin, which cannot bend outwardly and therefore the The door pin is kept inside the cylindrical housing (28) of the closing pin. Instead, when the closing pin (2) is in the extracted opening position, the collar (123) of the module cable does not interfere with the elastic flanks (24) of the closing pin and therefore the elastic flanks (24 ) can be bent outwardly and the door pin can be removed from the cylindrical housing (28) of the closing pin.
[0064] A spring (M) is mounted inside the housing (12) of the housing and acts on the structure (20) of the closing pin to push the closing pin upwards towards its extracted opening position.
[0065] The roller (I) is mounted on a support (15) disposed in the housing (12) of the box in order to act inside the cam. (3).
[0066] The roller (I) is a metal bar bent as a "Z". A first end of the roller is hinged to the support (15) of the housing, such that the roller (I) can rotate about an axis orthogonal to the sliding axis (X) of the closing pin and orthogonal to the flange (21) the closing pin. A second end of the roller has a tip suitable for acting on the cam (3).
[0067] With reference to Fig. 9, the cam (3) of the locking pin comprises a perimeter wall (30) that defines a housing in which a central island (31) with a substantially triangular shape is arranged. The central island (31) has a first side (32), a second side (33) and a third side (34). The slide rails (P1, P2, P3, P4) of the roller (I) are defined between the sides (32, 33, 34) of the central island and the perimeter wall (30), forming a closed circuit.
[0068] The cam (3) has four housings:
[0069] - a first carcass (S1) in the corner between the first side (32) and the third side (34) of the central island;
Petition 870170079138, of 10/17/2017, p. 29/45
8/12 [0070] - a second housing (S2) on the perimeter wall (30) of the cam above the corner between the first side (32) and the second side (33) of the central island;
[0071] - a third housing (S3) on the perimeter wall (30) of the cam under the corner between the second side (33) and the third side (34) of the central island; and [0072] - a fourth housing (S4) on the perimeter wall (30) of the cam above the corner between the third side (34) and the first side (32) of the central island.
[0073] In view of the above, four slide rails are defined in the cam (3): a first rail (P1) that goes from the first frame (S1) to the second frame (S2), a second track (P2) that goes from the second frame (S2) to the third frame (S3), a third track (P3) that goes from the third frame (S3) to the fourth frame (S4) and a fourth track that goes from the fourth frame (S4) to the first carcass (S1).
[0074] With reference to Fig. 9A, in an initial situation, the tip of the roller (I) is in the first housing (S1). When the user pushes the door (105) (first push), the closing pin (2) is pressed in the direction of the arrow (F1) against the action of the spring (M). Consequently, the roller tip (I) is disengaged from the first housing (S1), passes along the first rail (P1) and stops against the second housing (S2), as shown in Fig. 9B.
[0075] With reference to Fig. 9B, in this situation, the closing pin (2) is in a position of maximum retraction. When the user releases the door (105), the spring (M) pushes the closing pin in the direction of the arrow (F2) towards an extracted position. Consequently, the roller tip (I) is disengaged from the second housing (S2), passes along the second rail (P2) and is positioned on the third housing (S3). In this situation (not shown in the drawings), the closing pin (2) is in a position of maximum extraction. Therefore, when the user pushes the door (105) (the second push) again, the closing pin is pushed up against the action of the spring (M). Consequently, the roller tip (I) is disengaged from the third housing (S3), passes along the third rail (P3) and stops against the fourth housing (S4), as shown in Fig. 9C. When the user releases the door (105), the spring (M) pushes the closing pin (2) in the direction of the arrow (F3) and the cam roller from the fourth housing (S4) to the first housing (S1), passing along the fourth track (P4).
[0076] Returning to Figs. 5 and 5A, the lock (6) comprises a slide (60)
Petition 870170079138, of 10/17/2017, p. 30/45
9/12 slidably mounted on the housing (12) of the housing so that it slides along an axis (X) orthogonal to the sliding axis (Y) of the closing pin, moving from a non-functional rear position to a functional position where it engages and locks the closing pin. The slide (60) has two locking pins (62) that protrude frontally from the slide and are engaged in locking housings (21a) obtained on the lateral edges of the flange (21) of the closing pin, to lock the locking pin. closing, when the closing pin is in the retracted closing position, as shown in Fig. 10. The slide can be provided with only one locking pin (62) and the closing pin flange (2) can be supplied with only a locking housing (21a).
[0077] The actuator (5) can be any type of linear actuator suitable to impose a conversion to the lock (6).
[0078] Preferably, the actuator (5) comprises an electric motor (50) with a transmission shaft (51) on which an endless screw (52) is mounted, with the axis of rotation coinciding with the axis (X) of conversion of the slide. The worm screw (52) is engaged with a female screw (61) obtained from the slide. In this way, a rotation of the endless screw results in a conversion of the slide (60) in the direction of the axis (X).
[0079] The actuator (5) can be of the bistable type, that is, suitable to allow a forward passage and a backward passage of the lock (6). If the actuator comprises an electric motor (50), said electric motor must be able to rotate in both directions to allow for a forward and backward passage of the slide (60).
[0080] With reference to Fig. 6, the actuator (5) can be of a monostable type, that is, suitable to allow only one passage to the front of the lock (6). In this case, a return spring (M2) is arranged between the actuator (5) and the lock to return the lock to its non-operational return position. If the actuator comprises an electric motor (50), said electric motor can rotate in a single direction to allow a forward passage of the slide (60), while the backward passage of the slide is generated by the return of the spring (M2 ).
[0081] With reference to Fig. 7, an electromagnet (E) is mounted on the housing (12) of the housing in order to interact with a magnetic element (29) disposed under
Petition 870170079138, of 10/17/2017, p. 31/45
10/12 the structure (20) of the closing pin. The electromagnet (E) has a cylindrical shape with an axial hole (E1). The magnetic element (29) is a cable that projects in a lower position from the structure (20) of the closing pin to engage the axial hole (E1) of the electromagnet. The flange (21) of the closing pin is kept out of the electromagnet (E).
[0082] The electrical cables (E2) protrude from the electromagnet to be connected to the connector (16) or to a power supply. So that, when the electromagnet (E) is excited, it attracts the magnetic element (29) of the closing pin, pushing the closing pin to the retracted closing position against the action of the spring (M).
[0083] With reference to Fig. 8, the closing system (100) also comprises transmission means (T) that connect the slide (60) of the lock to the closing pin (2), in such a way that the movement of the slide by the non-operational backward position to the advanced operating position it automatically produces the movement of the closing pin (2) from the extracted opening position to the retracted closing position. A rack (64) is mounted on one side of the slide (60) so as to overlap laterally and frontally with respect to the slide (60). The rack (64) is engaged with a pinion-shaped gear (65) that is rotatably mounted on the housing with a rotation axis that is orthogonal to the lock conversion axis (X) and the pin conversion axis (Y) closing.
[0084] A sprocket part (66), with the same axis as the gear, but a larger diameter than the gear (65), is mounted on the gear (65). A rack (67) is mounted on the flange (21) of the closing pin, on the opposite side of the cam. (3). Accordingly, the transmission means (T) comprise the crack rack (64), the gear (65), the sprocket part (66) and the rack (67) of the locking pin.
[0085] The rack (67) of the locking pin engages with the sprocket part (66) of the gear. In such a way, when the actuator (5) is actuated to bring the lock (6) to the operational position forward, the lock rack (64) acts on the gear (65) and the sprocket part (66) that it engages in the rack (67) of the closing pin (2), automatically activating the closing pin (2) in the closing position, without the need for the user to manually actuate the closing pin (2).
Petition 870170079138, of 10/17/2017, p. 32/45
11/12 [0086] Referring to Fig. 11, the switch (4) has a flexible blade (40) that, when actuated, activates the switch that sends an electrical signal to a vehicle control unit.
[0087] A counterpart (41) is attached to a lower part of the flange (21) of the closing pin, close to the cam. (3). The switch (4) is mounted on the housing (12) of the housing, in a position such that the blade (40) of the switch is pushed by the counterpart (41) of the closing pin, when the closing pin goes from the retracted closing position to the extracted opening position. In this way, the vehicle's control unit receives the command signal when the closing pin is in the extracted opening position and has information about the position of the closing pin.
[0088] With reference to Figs. 5A, 12 and 13, the emergency mechanism (E) comprises an emergency device (7) provided with a central body (50) articulated to the housing so as to rotate about an axis (Z) orthogonal to the axis (Y) of the conversion of the closing pin and the axis (X) of the conversion of the slide (60) of the lock.
[0089] The emergency device (70) has a switch pin (71) in the shape of a parallelepiped or prism, which protrudes along the axis (Z) of rotation of the emergency device. The emergency device (70) comprises a first arm (72) that protrudes radially from the central body (70) in a direction parallel to the slide conversion axis (X) and a second arm (73) that protrudes radially from from the central body (70) of the emergency device, being spaced angularly from the first arm (72) by approximately 40 ° - 80 °. The second arm (73) has an "L" shape to define a retaining housing (74).
[0090] A fixing pin (63) protrudes laterally from the slide (60) of the lock. A fixing housing (21b) is obtained at a lateral edge of the flange (21) of the closing pin, above the locking housing (21a).
[0091] The first arm (72) of the emergency device is stopped at the fixing housing (21b) of the closing pin. The fixing pin (63) of the slide (60) is engaged with the retaining housing (74) of the second arm (73) of the emergency device.
[0092] The emergency mechanism (E) also comprises a hook (8) provided with a socket (80) that receives the pin (71) of the
Petition 870170079138, of 10/17/2017, p. 33/45
12/12 emergency. The socket (80) has a rectangular or polyhedral shape. Thus, the hook (8) is attached to the emergency device (7). Of course, the hook (8) can be integrated into the emergency device (7). The hook (8) also comprises a housing (81) suitable for receiving a pin (90) connected to an emergency rope (9) coming out of the box (10) to be manually operated by the user.
[0093] With reference to Fig. 12, when the user pulls the emergency rope (9) in the direction of the arrow (A1), the hook (8) rotates in the direction of the arrow (A2), activating the emergency device (7) in rotation. In view of the above, simultaneously, the first arm (72) of the emergency device acts on the closing pin, lowering the closing pin in the direction of the arrow (A3) and the second arm (73) of the emergency device acts on the slide (60) of the lock, moving the slide backwards in the direction of the arrow (A4) in such a way that the locking pin (62) of the slide is disengaged from the locking housing (21a) of the closing pin. In this way, the closing pin is unlocked and can go to its extracted opening position due to the spring thrust (M).
