[0043] In order to make the skilled in the art to which the present application belongs more clearly understand the present application, the following will be combined with the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application are described clearly and completely, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] The first aspect of the present application provides a lid driving and locking assembly, which can realize the sliding opening and closing of the lid, and locking after the lid is closed.

[0045] Please refer to Figure 1 and Figure 2 The lid driving and locking assembly provided by the present application comprises a mounting frame 100, a driven bracket 200, a locking mechanism and a driving mechanism. The driven bracket 200 is used to connect the lid 500, and the driven bracket 200 is slidingly connected to the mounting frame 100. The driven bracket 200 is provided with a tooth segment 210. The locking mechanism comprises a first locking piece 310 and a second locking piece 320. The first locking piece 310 and the second locking piece 320 cooperate with each other. The first locking piece 310 is connected to the driven bracket 200, and the second locking piece 320 is slidingly connected to the mounting frame 100. The driving mechanism comprises a restoring piece 410, a driving wheel 420, a driven cam 430 and a driven gear 440. The driving wheel 420 is connected in force transmission to the driven cam 430 and the driven gear 440. The driven gear 440 is engaged with the tooth segment 210 of the driven bracket 200. Wherein, the second locking piece 320 is driven by the driven cam 430 to slide relative to the mounting frame 100, so as to be unlocked with the first locking piece 310. The second locking piece 320 is driven by the restoring piece 410 to slide relative to the mounting frame 100, so as to be locked with the first locking piece 310. The driven bracket 200 is driven by the driven gear 440 to slide relative to the mounting frame 100 when the first locking piece 310 and the second locking piece 320 are in the unlocked state, so as to open or close the lid 500.

[0046] The driven bracket 200 is connected with the cover 500, and the driven bracket 200 is slidably connected with the mounting bracket 100, so that the driven bracket 200 can drive the cover 500 to slide along the mounting bracket 100, so that the cover 500 is opened or closed. The driven bracket 200 is provided with a tooth segment 210, which can drive the tooth segment 210 engaged with the driven gear 440 to move when the driven gear 440 rotates, so as to realize the sliding of the driven bracket 200 relative to the mounting bracket 100, and drive the cover 500 to slide.

[0047] The locking mechanism can lock the cover 500 after the cover 500 is closed, so as to reduce the risk that the cover 500 is thrown out due to inertia during vehicle driving or is thrown out due to centrifugal force when the vehicle is high-speed turning. The first locking part 310 and the second locking part 320 of the locking mechanism can be interlocked after the cover 500 is closed. Since the first locking part 310 is connected with the driven bracket 200, and the second locking part 320 is connected with the mounting bracket 100, when the driven bracket 200 slides relative to the mounting bracket 100 to close the cover 500, the first locking part 310 is connected with the second locking part 320 under the action of the restoring part 410 to be locked, so as to ensure that the cover 500 has good stability during vehicle driving. When charging is needed, the second locking part 320 is driven by the driven cam 430 to slide relative to the mounting bracket 100, the first locking part 310 and the second locking part 320 are separated, and the unlocking of the second locking part 320 and the first locking part 310 is realized. In some embodiments, the first locking part 310 is a locking pin, and the second locking part 320 is a locking hook. The locking hook can have a slight deformation performance, so that the locking hook can be locked or separated with the locking pin. In some embodiments, the first locking part 310 is a locking hook, and the second locking part 320 is a locking pin.

[0048] The driving mechanism can drive the driven bracket 200 to slide relative to the mounting bracket 100, so that the driven bracket 200 drives the cover 500 to slide, and the opening and closing of the cover 500 are realized. The driving mechanism can also drive the second locking part 320 to slide relative to the mounting bracket 100, so as to realize the unlocking of the second locking part 320 and the first locking part 310. The driving wheel 420, the driven cam 430 and the driven gear 440 are all rotatably connected with the mounting bracket 100. The driving wheel 420 of the driving mechanism can simultaneously drive the driven cam 430 and the driven gear 440 to rotate, so that one driving motor simultaneously drives two wheels, and the structure is compact and occupies small space.

[0049] The driven bracket 200 of the present application is connected with the cover 500 and the first locking part 310, and the structure is compact. Compared with the flip cover opening and closing, the present application adopts the sliding opening and closing of the cover 500, which occupies small space and has high safety. The present application adopts mechanical locking to further improve the safety performance.

[0050] In some embodiments, the driven gear 440 is provided with a half-tooth portion 441 and an engaging portion 442, the half-tooth portion 441 and the engaging portion 442 constitute the teeth of the whole circle of the driven gear 440, the half-tooth portion 441 is an arc surface, and the arc surface is concentric with the dedendum of the engaging teeth of the engaging portion 442, the engaging teeth of the tooth segment 210 are all the same, and when the arc surface is opposite to the tooth segment 210, the arc surface of the half-tooth portion 441 is in contact with or has a gap with the tooth segment 210, so that when the half-tooth portion 441 cooperates with the tooth segment 210, the driven bracket 200 is stationary when the driving wheel 420 rotates, the first locking member 310 is stationary, and the second locking member 320 slides, so as to realize the unlocking or locking of the first locking member 310 and the second locking member 320. The use of this structure may cause intermittent stop of the sliding of the driven bracket 200 relative to the mounting bracket 100, so that the opening or closing process of the flap cover 500 is not stable.

[0051] In some embodiments, referring to Figure 2 , Figure 5 and Figure 6 , the driven gear 440 is provided with a half-tooth portion 441 and an engaging portion 442, the half-tooth portion 441 and the engaging portion 442 constitute the teeth of the whole circle of the driven gear 440, the tooth segment 210 includes a half-tooth segment 211 and a sliding segment arranged in sequence; the engaging teeth of the half-tooth portion 441 and the half-tooth segment 211 are arranged in sequence in the axial direction of the driven gear 440, so that the driven bracket 200 is stationary when the half-tooth portion 441 cooperates with the half-tooth segment 211, so as to unlock or lock the second locking member 320 and the first locking member 310. The arc length of the half-tooth portion 441 can account for one-half of the circumference of the driven gear 440, or one-third of the circumference of the driven gear 440, the arc length of the half-tooth portion 441 and the length of the half-tooth segment 211 can be determined according to the locking stroke of the first locking member 310 and the second locking member 320, and the arc length of the half-tooth portion 441 is greater than or equal to the stroke of the second locking member 320 relative to the first locking member 310 to unlock, so that the cover is opened after being unlocked, or the cover is closed before being locked.

[0052] Referring to Figure 6 , the tooth width of the engaging teeth of the engaging portion 442 is greater than the tooth width of the engaging teeth of the half-tooth portion 441, and referring to Figure 5, the tooth width of the sliding section is greater than the tooth width of the half-tooth section 211, the meshing teeth of the meshing section 442 can mesh with the meshing teeth of the whole tooth section 210, i.e. the sliding section and the half-tooth section 211, and the meshing teeth of the half-tooth section 441 can mesh with the meshing teeth of the sliding section. The opening process of the cover 500 is unlocking first and then opening, specifically: the driving gear drives the driven gear 440 to rotate, the half-tooth section 441 of the driven gear 440 cooperates with the half-tooth section 211, and since the meshing teeth of the brake half-ring and the half-tooth section 211 are arranged in axial staggered manner along the driven gear 440, the driven gear 440 rotates while the driven support 200 remains stationary; the driving gear drives the driven cam 430 to rotate at the same time, the driven cam 430 drives the locking mechanism to slide relative to the mounting frame 100, so that the first locking piece 310 and the second locking piece 320 are unlocked. In the process of unlocking the first locking piece 310 and the second locking piece 320, the meshing section 442 gradually cooperates with the half-tooth section 211 with the rotation of the driven gear 440, and then gradually changes to the cooperation of the meshing section 442 with the sliding section, and then the cooperation of the half-tooth section 441 with the sliding section, driving the driven support 200 to slide relative to the mounting frame 100, the driven support 200 drives the cover 500 to slide and open the charging port. The closing process of the cover 500 is the reverse process of the opening, i.e. closing first and then locking: the driven support 200 slides relative to the mounting frame 100, so that the cover 500 closes the charging port, and then the locking mechanism slides relative to the mounting frame 100, so that the first locking piece 310 and the second locking piece 320 are locked, and the opening and closing processes of the cover 500 are stable and smooth.

[0053] In some embodiments, one of the driven support 200 and the mounting frame 100 is provided with the sliding block 220, and the other is provided with the sliding rail 110, and the sliding block 220 is slidingly connected to the sliding rail 110. In some embodiments, please refer to Figure 5 , the driven support 200 is provided with the sliding block 220, please refer to Figure 3 and Figure 4 , the mounting frame 100 is provided with the sliding rail 110, and in other embodiments, the driven support 200 is provided with the sliding rail 110, and the mounting frame 100 is provided with the sliding block 220. The sliding rail 110 can be a sliding groove, and the sliding block 220 is matched and arranged in the sliding groove, the slot width of the sliding groove is less than the groove bottom width of the sliding groove, and the slot of the sliding groove faces downward to adapt to more arrangement angles of the sliding groove. In some embodiments, the sliding block 220 is provided with a plurality of sliding blocks, the sliding rail 110 is provided with a plurality of sliding rails, the plurality of sliding rails 110 are arranged at intervals, and the number of the sliding blocks 220 is the same as and corresponds to the number of the sliding rails 110, so as to improve the stability of the sliding process of the driven support 200 relative to the mounting frame 100. The number of the sliding blocks 220 can be two, three, four or five, etc. In some embodiments, the sliding block 220 is provided with two sliding blocks, and the sliding groove is provided with two sliding grooves, which not only ensures the stability, but also reduces the processing difficulty.

[0054] In some embodiments, please refer to Figure 5The sliding section comprises two first and second tooth sections 212 and 213 arranged at an angle, and the second tooth section 213 is adjacent to the half tooth section 211. The first and second tooth sections 212 and 213 constitute the sliding section. After the engaging portion 442 of the driven gear 440 engages with the half tooth section 211, the driven gear 440 successively engages with the second tooth section 213 and the first tooth section 212, so that the driven bracket 200 slides relative to the mounting bracket 100, and the driven gear 440 rotates around its own axis, and the position of the driven gear 440 does not change. The first and second tooth sections 212 and 213 of the driven bracket 200 are arranged at an angle, and the driven bracket 200 has a first movement direction and a second movement direction arranged at an angle. After the flap 500 is connected to the vehicle body, the first movement direction is the movement direction of the flap 500 protruding from the vehicle body, and the second movement direction is parallel to the side wall 2000 of the vehicle body where the flap 500 is located. In this way, when the flap 500 is opened, the flap 500 first protrudes from the vehicle body and then translates to achieve opening. When the flap 500 is closed, the flap 500 first translates and then extends into the vehicle body to form an integral part with the vehicle body, and the appearance is consistent.

[0055] Correspondingly, please refer to Figure 4 The sliding rail 110 comprises two first and second rail sections 111 and 112 connected to each other and arranged at an angle. During the process in which the driven gear 440 acts on the half tooth section 211 and the second tooth section 213, the sliding block 220 acts on the first rail section 111. During the process in which the driven gear 440 acts on the first tooth section 212, the sliding block 220 acts on the second rail section 112. In some embodiments, the included angle between the first and second rail sections 111 and 112 is an obtuse angle, for example, 110°-160° or 120°-150°, and the included angle between the first and second tooth sections 212 and 213 is equal to the included angle between the first and second rail sections 111 and 112. The obtuse angle makes the sliding process of the driven bracket 200 relative to the mounting bracket 100 more smooth.

[0056] In some embodiments, the connection between the first and second tooth sections 212 and 213 is rounded, so that the flap 500 changes the movement direction more smoothly. In some embodiments, the second tooth section 213 and the half tooth section 211 can be arranged in a straight line, and in other embodiments, the half tooth section 211 is arc-shaped.

[0057] In some embodiments, please refer to Figure 5 The driven bracket 200 comprises a first driven plate 230, which is a knife-shaped plate. The web of the knife-shaped plate is provided with the first and second tooth sections 212 and 213 and the half tooth section 211. The first locking member 310 is located at the connection between the first and second tooth sections 212 and 213. The driven plate is provided with the sliding block 220 or the sliding rail 110, so that the overall structure occupies less space and is more compact.

In other embodiments, the driving wheel 420 is a driving gear, and the driven gear 440 is connected to the driving gear through a gear disc 470. Specifically, the gear disc 470 is coaxially arranged with the driven gear 440, the driving gear is engaged with the gear disc 470, and the driving gear rotates to drive the gear disc 470 to rotate, thereby driving the driven gear 440 to rotate. The diameter of the gear disc 470 is smaller than the diameter of the driven gear 440, i.e., the engagement teeth of the driven gear 440 protrude out of the gear disc 470.

[0059] In some embodiments, referring to Figure 4 , the driving wheel 420 is a driving gear, and the driven cam 430 is rotatably connected to the mounting frame 100.

In some embodiments, the mounting frame 100 includes a first support plate 115 and two side plates 117. The two side plates 117 are oppositely arranged and connected to the first support plate 115. The two side plates 117 and the first support plate 115 jointly form the locking slot. In some embodiments, the side plate 117 is bent away from the first support plate 115, so that the slot opening of the locking slot has a smaller width than the slot bottom of the locking slot, so as to provide support for the locking piece 330 when the slot opening of the locking slot faces downward. In some embodiments, the locking piece 330 and the second locking piece 320 are an integral structure, and the locking piece 330 can be a locking plate or a locking block.

[0062] In some embodiments, referring to Figure 7The side plate 117 is connected with a reinforcing rib 114, and the reinforcing rib 114 is connected to the first support plate 115 to improve the strength of the locking slot. In some embodiments, the locking piece 330 extends out of the locking slot along the sliding direction of the locking piece 330, the part of the locking piece 330 extending out of the locking slot is connected to the second locking piece 320, and the part of the locking piece 330 extending out of the locking slot is provided with a limiting surface 331 which acts on the outer side of the slot wall of the locking slot, and when the driven cam 430 moves away from the locking piece 330, the limiting surface 331 is abutted against the slot wall of the locking slot under the restoring action of the restoring piece 410 to limit the movement.

[0063] In some embodiments, the restoring piece 410 is an elastic piece, and the two ends of the elastic piece are respectively connected to the locking piece 330 and the mounting frame 100.
