[0008] Furthermore, the support frame is inclined, and the top block has an inclined surface parallel to the support frame, with the inclined surface of the top block abutting against the battery pack.

[0009] Furthermore, a locking structure is provided between the connecting frame and the top block.

[0010] Furthermore, the locking structure includes a bolt that passes through the top block and is threadedly connected to the connecting bracket.

[0011] Furthermore, the top block has a protrusion at its end, the connecting bracket has a groove that mates with the protrusion, and the bolt is threaded through the bottom wall of the protrusion and the groove.

[0012] Furthermore, a support block is fixedly connected to the lower side of the mounting cavity of the vehicle frame. The support block is located below the battery pack, and the support block abuts against the battery pack.

[0013] Furthermore, a top cover is detachably connected to the vehicle frame, the top cover being located above the battery pack, and the top cover abutting against the battery pack.

[0014] Furthermore, a gap is left between the support frame and the vehicle frame.

[0015] Beneficial effects: The battery pack is supported and restricted by the support frame fixed under the vehicle frame, providing space for the battery pack. The battery pack is easy to install and position. At the same time, the battery pack is quickly fixed by the connecting bracket and the top block. Disassembly is convenient.

[0020] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, a vehicle frame battery pack fixing structure includes a vehicle frame 11. The main shape of the vehicle frame is a common inverted triangle. The vehicle frame as a whole is a frame structure with relatively large gaps.

[0023] Among them, such as Figure 2 and Figure 3As shown, a support frame 12 is connected to one side of the frame 11. The support frame 12 is used to support the battery pack. The support frame 12 and the interior of the frame 11 form a mounting cavity 13. The cross-section of the mounting cavity 13 is an inverted triangle. The battery pack is located on the side of the inverted triangle of the mounting cavity 13 and is housed in the support frame 12. The battery pack is set at an angle for easy fixing.

[0024] The support frame 12 has several through holes, which can be used for heat dissipation of the battery pack.

[0025] There are gaps between the upper and lower ends of the support frame 12 and the vehicle frame 11. The gaps are much smaller than the size of the battery pack, which makes it convenient for staff to move the battery pack from the bottom without affecting the normal installation of the battery pack.

[0026] Furthermore, a support block 14 is fixedly installed at the bottom of the inverted triangle of the frame 11, with the end face of the support block 14 facing the support frame 12. The support block 14 is used to cooperate with the support frame 12 to install the battery pack.

[0027] To facilitate the installation and removal of the battery pack, the cross-sectional size of the support block 14 is smaller than the side size of the battery pack, making it easier to push the battery pack from the bottom.

[0028] The battery pack is supported by a support frame 12. One end of the battery pack abuts against the support block 14, and the other end of the battery pack abuts against the handlebars of the frame 11, thus securing the battery pack.

[0029] The support frame 12 and support block 12 work together with the frame 11 to support the battery pack. To ensure the stability of the battery pack during the movement of the motorcycle, the frame 11 is connected to a fixing structure above the battery pack.

[0030] The fixing structure is used to restrict the movement of the battery pack. The fixing structure includes a connecting frame 15, which is fixedly connected to the vehicle frame 11. A top block 16 is connected to the connecting frame 15, and the top block 16 abuts against the battery pack.

[0031] The top block 16 has a bevel 17 facing the battery pack side, and the bevel 17 fits against the side wall of the battery pack to ensure a secure fit.

[0032] A locking structure is provided between the top block 16 and the connecting frame 15. The movement of the top block 16 is restricted by the locking structure, thereby restricting the movement of the battery pack. When the top block 16 is detached, the battery pack can be detached and moved.

[0033] In this embodiment, as Figure 4As shown, the locking structure includes a bolt 18, a protrusion 19 on one side of the top block 16, the protrusion 19 being located on the side of the top block 16 away from the inclined surface, and a groove 20 on the side of the connecting bracket 15 facing the top block 16, the protrusion 19 being able to be inserted into the groove 20. The bolt 18 is threadedly connected to the bottom wall of the protrusion 19 and the groove 20. When fixing is required, the bolt 18 locks the bottom of the protrusion 19 and the groove 20, and the top block 16 and the connecting bracket 15 are fixedly connected.

[0034] The groove 20 has an upward opening, and one side of the groove 20 is through, which makes it easy for the top block 16 to be placed vertically and horizontally into the groove. The bolt 18 is vertically set to fix the top block 16.

[0035] In another embodiment, the bolt 18 can be set horizontally, and the bolt 18 and the top block 16 are rotatably connected. The bolt 18 passes horizontally through and is threadedly connected to the connecting frame 15, which facilitates the control of moving the top block 16, thereby achieving the effect of fixing the battery pack.

[0036] Furthermore, a top cover 21 is also connected to the frame 11. The top cover 21 is detachably connected to the handlebars of the frame 11. The top cover 21 is used to connect the seat. At the same time, the top cover 21 has several support columns 22 on the side facing the battery pack. The support columns 22 abut against the battery pack to achieve an additional fixing effect on the battery pack.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
