[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] The present utility model provides a detachable multi-functional electric vehicle battery box. As Figures 1-4 shown, the detachable multi-functional electric vehicle battery box includes a box body 1, a clamping mechanism 2 disposed inside the box body 1 for clamping the battery, a cover plate 3 disposed on the top of the box body 1 for covering the top opening of the box body 1, and a fixing structure 4 disposed on the box body 1 for fixing the cover plate 3 on the box body 1. The fixing structure 4 includes positioning boxes 41 symmetrically disposed at the outer edge of the top opening of the box body 1 for contacting the bottom edge of the cover plate 3, insertion plates 42 disposed at the bottom of the cover plate 3 corresponding to the positioning boxes 41, positioning heads 43 symmetrically disposed inside the positioning boxes 41, and a driving structure 44 disposed inside the positioning boxes 41 for driving the two positioning heads 43 to move closer to or away from the insertion plates 42. A positioning hole 423 for the insertion plate 42 to insert into the inside of the positioning box 41 is formed on the positioning box 41, and a positioning hole 423 adapted to the positioning head 43 is formed on the insertion plate 42.

[0031] During use, first place the battery inside the box body 1, and use the clamping mechanism 2 to clamp and buffer the battery to prevent the battery from colliding with the box body 1 during the operation of the electric vehicle. After the battery is placed, cover the cover plate 3 on the top of the box body 1. At this time, in order to avoid the problem that in the existing box body 1, when connecting the cover plate 3 and the box body 1, it is mostly fixed by screws, and when there is a problem with the battery during the driving journey, tools are needed to open the cover plate 3, which is not convenient for quick maintenance. The cover plate 3 can be quickly disassembled and assembled by using the fixing structure 4. The insertion plate 42 can be disassembled and assembled by using the driving structure 44, and then the cover plate 3 can be easily removed along the top of the box body 1 by removing the insertion plate 42 along the relief groove 411.

[0032] Specifically, the driving structure 44 includes a telescopic rod 441 fixedly arranged between the positioning head 43 and the positioning box 41, a spring 442 sleeved on the telescopic rod 441, a connecting plate 443 for connecting the two positioning heads 43, and a pull rod 444 fixedly installed on the connecting plate 443 and passing through the side of the positioning box 41 away from the box body 1. The two ends of the spring 442 are fixedly connected to the positioning head 43 and the positioning box 41 respectively. To achieve reasonable disassembly and assembly of the plug board 42, when fixation is required during the disassembly and assembly process, first move the pull rod 444 towards the outside of the positioning box 41, which drives the positioning head 43 away from the positioning hole 423, facilitating the sliding insertion of the plug board 42 into the positioning hole 423. At this time, release the pull rod 444, and the spring 442 inside the positioning box 41 drives the telescopic rod 441 to expand and contract, thereby driving the positioning head 43 to approach the plug board 42 until it penetrates the plug board 42 to achieve the fixation effect on the plug board 42, thus completing the entire installation. When disassembly is required, move the pull rod 444 towards the outside to drive the positioning head 43 out of the plug board 42, facilitating its removal.

[0033] Among them, to achieve the quick removal of the cover plate 3; the cross-section of the plug board 42 is T-shaped. The plug board 42 has an insertion portion 421 for passing through the cover plate 3 and inserting into the positioning box 41, and a limiting portion 422 located at one end of the insertion portion 421 for contacting the top surface of the cover plate 3. The insertion portion 421 is slidably connected to the cover plate 3. Among them, the positioning hole 423 is opened at one end of the insertion portion 421 away from the limiting portion 422; this can be achieved by using the plug board 42.

[0034] Furthermore, the detachable multi-functional electric vehicle battery box further includes a clamping mechanism 2, which includes a support block 21 fixedly arranged at the bottom of the box body 1, a fixing plate 22 fixedly arranged on the side of the support block 21 away from the inner wall of the box body 1, and an adjusting plate 23 slidably arranged on the side of the fixing plate 22 away from the support block 21. A rubber clamping block 24 is fixedly arranged at one end of the adjusting plate 23 away from the fixing plate 22, and an electric cylinder 25 fixedly connected to the support block 21 is fixedly arranged at one end of the adjusting plate 23 away from the rubber clamping block 24. When quickly removing and installing the battery, the clamping mechanism 2 can be used to drive the adjusting plate 23 to move away from the center along the fixing plate 22 by starting the electric cylinder 25, thereby driving the rubber clamping block 24 to release the battery, facilitating its removal for maintenance. After the maintenance is completed, the electric cylinder 25 is used to drive the adjusting plate 23 and the rubber clamping block 24 to clamp the battery, thus completing the fixation.

[0035] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
