[0020] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a quick disassembly and assembly device, which is used to install an object on a block 100. The quick disassembly and assembly device includes a connecting bar 101 and a disassembly and assembly mechanism 300. The connecting bar 101 is fixed on the block 100. A hook 102 is provided on the side of the connecting bar 101. The object is placed on the connecting bar 101.

[0022] Specifically, the object is a battery pack 200, and the quick disassembly and assembly device is compatible with the battery pack 200. In this embodiment, the connecting bar 101 is fixed to the block 100 by screws, wherein the block 100 refers to any object, and the connecting bar 101 can also be a structure integrally formed with the block 100.

[0023] The disassembly and assembly mechanism 300 is installed on the side of the object and is buckled with the hook claw 102. The disassembly and assembly mechanism 300 includes an upper buckle 301 and a buckle 400. The first end of the upper buckle 301 is fixed to the side of the object, and the second end of the upper buckle 301 is provided with a rotatable first roller 302, and the end of the first roller 302 is provided with a clamping assembly 303. The first end of the buckle 400 is provided with a rotatable second roller 401, and the second roller 401 is provided with a pull rod 402, which is fixedly connected to the first roller 302. The second end of the buckle 400 is provided with a cross bar 403, and the buckle 400 is provided with a card slot 404. When the buckle 400 is buckled on the second end of the upper buckle 301, the hook claw 102 overlaps the cross bar 403, and the clamping assembly 303 is buckled with the card slot 404.

[0024] Specifically, the upper buckle 301 is a buckle structure, and the second end of the upper buckle 301 is a mounting platform structure with two wings, and the two wings are provided with relative mounting holes, and the first roller 302 is rotatably installed between the two wings through the clamping assembly 302, and the first roller 302 and the second roller 401 are connected by the pull rod 402 to form an I-shaped structure. In the unlocked state, the buckle 400 is separated from the upper buckle 301, and the second roller 401 is placed in the lower front of the first roller 302. When buckling, the buckle 400 is lifted up and close to the upper buckle 301, so that the buckle 400 wraps the upper buckle 301, and the second roller 401 is flipped and placed above the first roller 302. At this time, the hook 102 overlaps the cross bar 403, and the hook direction of the hook 102 faces downward, and the hook 102 has a certain deformation ability. During the buckling period, the hook 102 overlaps the cross bar 403 to apply a downward force to the buckle 400. It should be noted that the second roller 401 is actually flipped and placed on the upper rear of the first roller 302, that is, on the side closer to the object, so that the pull rod 402 has the ability to resist the downward force of the first roller 302 while also having the force to pull the buckle 400 toward the object. Based on the above-mentioned force coordination, the disassembly and assembly mechanism 300 can realize rapid assembly of the object, and the buckle component 303 is buckled with the slot 404 to further stabilize the assembly structure. When unlocking, it is only necessary to drive the clamping component 303 out of the slot 404 and apply a force to move the buckle 400 away from the object to achieve rapid unlocking.

[0025] Furthermore, the snap-on assembly 303 includes a stud 3031, an elastic member 3032 and a stop block 3033. The stud 3031 is installed on the second end of the upper buckle 301 and is rotatably connected to the first roller 302. A cavity 3034 with an opening on one side is provided in the stud 3031. The elastic member 3032 is installed in the cavity 3034. The first end of the elastic member 3032 is connected to the bottom of the cavity 3034, and the second end of the elastic member 3032 is connected to the stop block 3033. The side of the stop block 3033 away from the elastic member 3032 is placed outside the cavity 3034. When the buckle 400 is buckled on the second end of the upper buckle 301, the stop block 3033 is buckled with the slot 404. By pushing the stop block 3033 back into the cavity 3034, the snap-on assembly 303 is disconnected from the slot 404.

[0026] Specific implementation: When the buckle 400 is buckled on the upper buckle 301, the block 3033 contacts the inner wall of the buckle 400 and rebounds in the cavity 3034. At this time, the elastic member 3032 is compressed until the block 3033 is pulled to the slot 404. At this time, the elastic member 3032 is elastically released, and the block 3033 is pushed into the slot 304 to achieve the snap connection. The way to disconnect the snap connection with the slot 304 is to push the block 3033 back into the cavity 3034 through external force, and at the same time pull the buckle 400 out of the upper buckle 301, wherein the elastic member 3032 adopts a spiral spring structure.

[0027] Furthermore, the quick disassembly and assembly device also includes a shell 500 that is sleeved on the buckle 400, and a pressing piece 501 is provided on the shell 500. The setting position of the pressing piece 501 corresponds to the setting position of the card slot 404, wherein the pressing piece 501 is pressed by external force to push the block 3033 connected in the card slot 404 back into the cavity 3034, and the pressing piece 501 is made of flexible material.

[0028] Specifically, the housing 500 and the pressing member 501 are an integrally formed injection-molded structure made of plastic material, which is convenient for the user to press the pressing member 501 and the outer pull buckle 400 with one hand at the same time to achieve quick disassembly and assembly.

[0029] Furthermore, a paddle 405 is provided on the buckle 400 .

[0030] Specifically, the paddle 405 is arranged at the top of the buckle 400. When the user operates with one hand, the index finger presses against the paddle 405, and the remaining fingers are conveniently used to hold the shell 500 and press the pressing piece 501. The inner wall of the buckle 400 is provided with a transition slope and chamfering treatment around the slot 404 to facilitate the rebound of the block 3033 and improve the smoothness during disassembly and assembly.

[0031] Furthermore, two groups of disassembly and assembly mechanisms 300 are provided and respectively installed on both sides of the object, two hook claws 102 are provided and respectively arranged on both sides of the connecting strip 101, and the two groups of disassembly and assembly mechanisms 300 are respectively buckled with the two hook claws 102.

[0032] The above are one or more implementation methods provided in combination with specific content, and it is not intended that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or any technical deduction or replacement based on the concept of the utility model, shall be deemed to be within the protection scope of the utility model.
