[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Example 1 In existing technology, the tailgate of an electric vehicle is only used for storage and cannot be reused after being removed from the vehicle. If users want to carry the items in the tailgate with them, they need to carry a separate suitcase and transfer the items from the tailgate to the suitcase, which reduces travel efficiency.

[0026] In view of this, the present utility model provides a tailgate assembly, including: a tailgate body 100 and a mounting base 200, the mounting base 200 being used for mounting on a tailgate bracket, the tailgate body 100 and the mounting base 200 being detachably connected; one of the tailgate body 100 and the mounting base 200 is provided with a locking hook structure, and the other is provided with a locking tongue structure, the locking tongue structure being able to cooperate with the locking hook structure to connect or detach the tailgate body 100 and the mounting base 200.

[0027] Please see Figure 1 The tail box body 100 and the mounting base 200 are fixed together by a locking tongue structure and a locking hook structure, thus mounting the tail box body 100 on the tail box bracket of the electric vehicle. During normal riding, the tail box body 100 has a storage function. When it is necessary to detach the tail box body 100 from the electric vehicle, the locking tongue structure and the locking hook structure can be disconnected, thereby separating the tail box body 100 from the mounting base 200. Therefore, the tail box assembly not only serves as a storage compartment for the electric vehicle but can also be independently detached from the vehicle for reuse. It is easy to assemble and disassemble, improving travel efficiency.

[0028] It should be noted that a locking hook structure can be provided on the tailgate body 100 and a locking tongue structure on the mounting base 200; alternatively, a locking hook structure can be provided on the mounting base 200 and a locking tongue structure on the tailgate body 100. This embodiment uses a locking hook structure on the tailgate body 100 and a locking tongue structure on the mounting base 200 as an example for explanation. The other configuration method is based on the same principle and will not be described in detail below.

[0029] Furthermore, the latch structure can adopt various types such as common spring latches, three-pronged latches, or straight latches, while the hook structure can adopt various types such as common crescent hooks, lock hooks, or combination lock hooks. Since all types of latch and hook structures are common in the mechanical field, this embodiment only describes one possible configuration.

[0030] In an optional embodiment, the lock hook structure includes a slot 120 and a lock body 130. The slot 120 is located on the side wall of the tail box body 100, and the lock body 130 is located inside the slot 120. The mounting base 200 is provided with a locking tongue structure, which includes a locking tongue 240 that is inserted into the slot 120.

[0031] Please see Figure 2 and Figure 4 In this embodiment, the latch 240 is a straight latch, and the lock body 130 is a combination lock. The latch 240 can be inserted into the slot 120 and connected to the lock body 130 to fix the tail box body 100 to the mounting base 200. The latch 240 can also be removed from the slot 120 and separated from the lock body 130 to separate the tail box body 100 from the mounting base 200.

[0032] The tail box assembly has a locked state and an unlocked state. In the locked state, the bolt 240 is inserted into the slot 120, and the lock body 130 is in a limiting engagement with the bolt 240. In the unlocked state, the lock body 130 is disconnected from the bolt 240, and the bolt 240 can be removed from the slot 120.

[0033] After the mounting bracket 200 is installed onto the tailgate bracket of the electric vehicle, the position of the locking tongue 240 is fixed. By gradually moving the slot 120 on the side wall of the tailgate body 100 closer to the locking tongue 240, the locking tongue 240 can be inserted into the slot 120, thus locking the tailgate assembly. After unlocking, by gradually moving the slot 120 on the side wall of the tailgate body 100 away from the locking tongue 240, the locking tongue 240 can be removed from the slot 120, thus separating the tailgate body 100 from the mounting bracket 200.

[0034] In an optional embodiment, the latch 240 is provided with a limiting groove 241, and the lock body 130 is provided with a limiting block. In the locked state, the limiting block extends into the limiting groove 241; in the unlocked state, the limiting block disengages from the limiting groove 241.

[0035] Please see Figure 2 A limiting groove 241 is provided at the end of the latch 240 facing the tailgate body 100. The limiting groove 241 can be either a through groove or a recess. A limiting block is provided correspondingly in the lock body 130 within the slot 120. When the latch 240 is fully inserted into the slot 120, the limiting block engages with the limiting groove 241, locking the position of the tailgate body 100. By disengaging the limiting block from the limiting groove 241, the tailgate body 100 can be removed from the mounting base 200. Alternatively, a positioning pin can be provided at the end of the latch 240 facing the tailgate body 100, and a corresponding positioning hole can be provided in the lock body 130. The tailgate body 100 can be fixed to the mounting base 200 through the engagement of the positioning pin and the positioning hole. A first magnetic element can be provided at the end of the locking tongue 240 facing the tail box body 100, and a second magnetic element can be provided on the lock body 130. The tail box body 100 and the mounting base 200 can be fixed by the magnetic attraction between the first magnetic element and the second magnetic element.

[0036] As an alternative, the side wall of the tailgate body 100 is provided with an unlocking button 140, which is connected to the limit block in a transmission manner.

[0037] Please see Figure 4 The unlock button 140 is connected to the limit block via a transmission structure. In the locked state, pressing the unlock button 140 temporarily disengages the limit block from the limit groove 241, allowing the tail box body 100 to be removed from the mounting base 200. Releasing the unlock button 140 resets the limit block, enabling the tail box body 100 to be locked again.

[0038] The advantage of using a combination lock on the lock body 130 is that it can achieve double locking. Only after turning to the correct combination and pressing the unlock button 140 can the tail box body 100 be separated from the mounting base 200. Strangers who do not know the combination cannot take away the tail box body 100, thus ensuring privacy and security.

[0039] In an optional embodiment, the mounting base 200 includes a sliding platform 210 and a locking platform 220. The locking platform 220 is vertically connected to one side of the sliding platform 210, and the locking tongue 240 is disposed on the locking platform 220, with the extension direction of the locking tongue 240 parallel to the sliding platform 210.

[0040] Please see Figure 2 The sliding platform 210 and the locking platform 220 are connected to form an L-shaped cross-section, facilitating the connection and disassembly of the tail box body 100 and the mounting base 200. After the mounting base 200 is installed on the tail box bracket of the electric vehicle, the sliding platform 210 is in a horizontal position, and the locking platform 220 is in a vertical position. Two locking tongues 240 are spaced apart on the locking platform 220, and the extension direction of the two locking tongues 240 is parallel to the sliding platform 210, so that the tail box body 100 only needs to slide on the sliding platform 210 to the vicinity of the locking platform 220 to complete the locking, which is simple and reliable to use.

[0041] In an optional embodiment, the tailgate body 100 and the sliding platform 210 are slidably connected by a slide rail structure. The slide rail structure includes a sliding groove 110 and a slide rail 230. One of the groove 110 and the slide rail 230 is disposed on the sliding platform 210 and extends perpendicularly to the locking platform 220. The other of the groove 110 and the slide rail 230 is disposed on the tailgate body 100.

[0042] Please see Figure 2 and Figure 3 In this embodiment, the track groove 110 is integrally injection molded into the bottom of the tailgate body 100, and the slide rail 230 is integrally injection molded into the upper surface of the sliding platform 210. Alternatively, the track groove 110 can be located on the upper surface of the sliding platform 210, and the slide rail 230 can be located at the bottom of the tailgate body 100, as long as a sliding engagement between the track groove 110 and the slide rail 230 is achieved. The extension directions of both the track groove 110 and the slide rail 230 are perpendicular to the locking platform 220, allowing the tailgate body 100 to be horizontally pushed onto the sliding platform 210 and slid near the locking platform 220 to complete the locking process. The sliding engagement between the track groove 110 and the slide rail 230 serves as a guide and limit, facilitating the engagement of the locking tongue 240 with the slot 120.

[0043] In an optional embodiment, both the track groove 110 and the slide rail 230 have T-shaped cross-sections.

[0044] The T-shaped cross-section of the track groove 110 and the slide rail 230 not only guides the sliding of the tail box body 100, but also positions the tail box body 100. This prevents the slide rail 230 from detaching from the track groove 110 when sliding on it, and also avoids shaking, making the sliding between the tail box body 100 and the mounting base 200 smoother and more stable.

[0045] In an optional embodiment, a pull rod groove 150 is provided at the bottom of the side wall of the tail box body 100, and a telescopic pull rod 160 is provided in the pull rod groove 150.

[0046] Please see Figure 4 After the tail box body 100 is fixed to the mounting base 200, the telescopic rod 160 will be hidden in the rod groove 150 on the side of the tail box body 100, without affecting the use of the tail box body 100 as an electric vehicle tail box. After the tail box body 100 is removed from the mounting base 200, if the tail box body 100 is placed vertically, the telescopic rod 160 can be taken out from the rod groove 150, and the tail box body 100 can be moved by pulling the telescopic rod 160.

[0047] Furthermore, the tail box body 100 is detachably connected to casters 170, and the casters 170 and the telescopic rod 160 are respectively set on the opposite side walls of the tail box body 100.

[0048] Please see Figure 3 When the tail box body 100 is used as an electric vehicle tail box, the casters 170 can be detached from the tail box body 100 and placed inside the tail box body 100, reducing the size of the tail box body 100 and improving its aesthetics. The casters 170 can be detachably connected to the tail box body 100 via a threaded connection. When the tail box body 100 needs to be used as an independent suitcase, the casters 170 are then installed back onto the tail box body 100. The casters 170 are connected to the tail box body 100 via threaded rods, with the casters 170 and the telescopic rod 160 located on opposite sides of the tail box body 100, facilitating the tail box body 100's movement on the ground. The telescopic rod 160 and the casters 170 allow the tail box body 100 to be easily moved around like a suitcase, making it convenient to use.

[0049] It should also be noted that, in order to balance lightness and sturdiness, the tail box body 100 is preferably made of aerospace-grade ABS plastic (Acrylonitrile Butadiene Styrene, a terpolymer of acrylonitrile, butadiene, and styrene) and PC plastic (Polycarbonate), so as to achieve both lightweight and impact resistance of the tail box body 100.

[0050] Example 2 This utility model provides an electric vehicle, including a tail box bracket and a tail box assembly as described in Embodiment 1, wherein the mounting base 200 in the tail box assembly is mounted on the tail box bracket.

[0051] Mounting bracket 200 can be fixed to the tail box bracket of the electric vehicle with screws. Since the electric vehicle has all the structures of the tail box assembly, it has all the beneficial effects described in Embodiment 1, which will not be repeated here.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
