The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 5 As shown, this embodiment provides a vehicle frame battery assembly structure, which includes a vehicle frame 1, a battery body 2, a snap-fit ​​component 3, and a lock 4. The vehicle frame 1 has a receiving cavity 11; the battery body 2 is located within the receiving cavity 11, and one end of the battery body 2 has a snap-fit ​​groove 21 and a snap-fit ​​fixing groove 22; the snap-fit ​​component 3 is installed at one end of the receiving cavity 11, and the snap-fit ​​component 3 has a snap-fit ​​post 31 and a snap-fit ​​fixing block 32. The snap-fit ​​post 31 snaps into the snap-fit ​​groove 21, and the battery body 2 can rotate around the snap-fit ​​post 31 as an axis to engage the snap-fit ​​fixing block 32 and the snap-fit ​​fixing groove 22; the lock 4 is installed at the other end of the receiving cavity 11 and can lock or release the other end of the battery body 2 to the vehicle frame 1.

[0033] Using the battery assembly structure of this utility model, when installing the battery body 2, first insert the snap-fit ​​post 31 into the snap-fit ​​groove 21 of the battery body 2, then rotate the battery body 2 around the snap-fit ​​post 31 as the axis, so that the snap-fit ​​fixing block 32 is snapped into the snap-fit ​​fixing groove 22, thereby fixing one end of the battery body 2 by the snap-fit ​​part 3, and then locking the other end of the battery body 2 onto the frame 1 by the lock 4, thus realizing the installation of the battery body 2 and the frame 1; similarly, when disassembling the battery body 2, first release the other end of the battery body 2 by the lock 4, then rotate the battery body 2, so that the snap-fit ​​fixing block 32 and the snap-fit ​​fixing groove 22 are disengaged, and then the snap-fit ​​post 31 and the snap-fit ​​groove 21 are disengaged, thus realizing the disassembly of the battery body 2 and the frame 1. The above assembly method facilitates the assembly and disassembly of the battery body 2 and the frame 1, solving the problem of difficult assembly and disassembly of the battery body 2 and the frame 1 in the prior art. Furthermore, by having the snap-fit ​​post 31 snap into the snap-fit ​​slot 21 and the snap-fit ​​fixing block 32 snap into the snap-fit ​​fixing groove 22, this arrangement effectively ensures the stability of the battery body 2 and the frame 1 after installation, avoiding the problem of unstable installation of the battery body 2 and the frame 1 in the prior art. Utilizing the frame-battery assembly structure of this utility model, the problem of difficult disassembly and unstable connection of the frame and battery in electric vehicles in the prior art is effectively solved.

[0034] In some embodiments, to ensure that the snap-fit ​​post 31 does not disengage when rotating within the snap-fit ​​groove 21, the snap-fit ​​post 31 has a limiting groove 311, and the snap-fit ​​groove 21 has a limiting protrusion 211. The limiting protrusion 211 is located within the limiting groove 311 and engages with the limiting groove 311 in a limiting engagement along the length of the receiving cavity 11. This configuration ensures that when the battery body 2 rotates around the snap-fit ​​post 31 as an axis, the battery body 2 and the snap-fit ​​member 3 will not disengage.

[0035] Optionally, the snap-fit ​​post 31 may also have a limiting protrusion 211, and the snap-fit ​​slot 21 may also have a limiting groove 311.

[0036] In this embodiment, as Figure 5 As shown, the snap-fit ​​fixing block 32 has multiple snap-fit ​​blocks 321. The multiple snap-fit ​​blocks 321 are spaced apart along the height direction of the receiving cavity 11, and all the multiple snap-fit ​​blocks 321 are snapped into the inner wall of the snap-fit ​​fixing groove 22, which can further ensure the stability of the snap-fit ​​between the battery body 2 and the frame 1.

[0037] In some embodiments, the snap-fit ​​component 3 includes a snap-fit ​​base 33 and a connecting shell 34. The connecting shell 34 is mounted on the snap-fit ​​base 33, which is connected to the bottom wall of the receiving cavity 11. Furthermore, the connecting shell 34 connects to the frame 1, thus further ensuring the connection strength between the snap-fit ​​base 33 and the frame 1, and preventing excessive shaking of the snap-fit ​​component 3 during riding due to bumps. The snap-fit ​​base 33 has a snap-fit ​​post 31 and a snap-fit ​​fixing block 32.

[0038] Optionally, the snap-fit ​​seat 33 includes a first seat and a second seat that are vertically connected. The first seat is connected to the bottom wall of the receiving cavity 11 by bolts, and the second seat has a snap-fit ​​post 31 and a snap-fit ​​fixing block 32.

[0039] Optionally, the snap-fit ​​seat 33 may also include a reinforcing rib connecting the first seat and the second seat, which can improve the connection strength between the first seat and the second seat.

[0040] Furthermore, the locking base 33 has a clearance hole 331, which allows the terminal connector of the battery body 2 to be avoided. The locking post 31 and the locking fixing block 32 are located on both sides of the clearance hole 331. This arrangement ensures that when the battery body 2 is rotated, the locking fixing block 32 is locked into the locking fixing groove 22.

[0041] In this embodiment, the battery assembly structure of the frame 1 also includes a mounting base 5. The mounting base 5 is adjustablely positioned at the other end of the receiving cavity 11, and the lock 4 is mounted on the mounting base 5. This allows the distance between the lock 4 and the battery body 2 to be adjusted according to actual conditions, facilitating the locking of the battery body 2 onto the frame 1.

[0042] Furthermore, the battery assembly structure of the frame 1 also includes fasteners. The mounting base 5 has a waist-shaped hole 51, which extends along the length of the receiving cavity 11. When the mounting base 5 is selected in a suitable position, the fastener is passed through the waist-shaped hole 51 and connected to the bottom wall of the receiving cavity 11. This achieves the purpose of connecting the mounting base 5 and the bottom wall of the receiving cavity 11, and at the same time, the position of the mounting base 5 can be adjusted.

[0043] In some embodiments, the battery assembly structure of the frame 1 further includes a protective shell 6. The protective shell 6 covers the lock 4 and is connected to the mounting base 5, thus providing protection for the lock 4.

[0044] In this embodiment, the lock 4 has a retractable latch 41, and the other end of the battery body 2 has a lock groove. The latch 41 can be inserted into or bypass the lock groove to lock or release the battery body 2 to the frame 1. The latch 41 can be extended or retracted by turning the key, thereby locking or releasing the battery body 2 to the frame 1.

[0045] This embodiment also provides an electric vehicle, including the battery assembly structure of the frame 1 described above. When installing the battery body 2 using this invention, the snap-fit ​​post 31 is first inserted into the snap-fit ​​groove 21 of the battery body 2. Then, the battery body 2 can be rotated around the snap-fit ​​post 31 as an axis, causing the snap-fit ​​fixing block 32 to snap into the snap-fit ​​fixing groove 22. This secures one end of the battery body 2 via the snap-fit ​​member 3, and then the other end of the battery body 2 is locked to the frame 1 using the lock 4, thus achieving the installation of the battery body 2 and the frame 1. Similarly, when disassembling the battery body 2, the lock 4 first releases the other end of the battery body 2, then the battery body 2 is rotated, causing the snap-fit ​​fixing block 32 to disengage from the snap-fit ​​fixing groove 22. Then, the snap-fit ​​post 31 is disengaged from the snap-fit ​​groove 21, thus achieving the disassembly of the battery body 2 and the frame 1. The above assembly method facilitates the disassembly and assembly of the battery body 2 and the frame 1, solving the problem of difficult disassembly and assembly of the battery body 2 and the frame 1 in the prior art. Furthermore, by having the snap-fit ​​post 31 snap into the snap-fit ​​slot 21 and the snap-fit ​​fixing block 32 snap into the snap-fit ​​fixing groove 22, this arrangement effectively ensures the stability of the battery body 2 and the frame 1 after installation, avoiding the problem of unstable installation of the battery body 2 and the frame 1 in the prior art. The electric vehicle using this utility model effectively solves the problems of difficult disassembly and unstable connection of the frame and battery in existing electric vehicles.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
