[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] refer to Figure 1The utility model provides a fast-change battery clamping mechanism for an off-road vehicle, comprising: a frame, a placement slot provided on the side of the frame, the placement slot movably connected to the battery pack 2, a clamping rod 7 provided above the battery pack 2, one end of the clamping rod 7 is rotatably connected to the side of a clamping handle 9, the side of the clamping handle 9 is rotatably connected to the inner wall of the frame 1 through the handle shaft, the other end of the clamping rod 7 is rotatably connected to a support pin 8, the support pin 8 is rotatably connected to the inner wall of the frame 1, the bottom of the clamping rod 7 is fixedly connected to a clamping column 12, a latch 5 is installed on the side of the frame 1, and a limiting mechanism 6 for limiting the rotation of the latch 5 is installed on the frame 1 on one side of the latch 5.

[0021] In the embodiment of the present utility model, reference Figure 1 As shown, the pressing handle 9 includes a front end 10 , the structure of the front end 10 is a cam structure, and a moving handle 11 is installed at the bottom of the front end 10 .

[0022] In the embodiment of the present utility model, reference Figure 1 As shown, the pressing column 12 includes a connecting rod 13 , a fixing column 14 is installed at the bottom of the connecting rod 13 , and the material of the fixing column 14 is rubber.

[0023] It should be noted that the frame is the main structural member, and the battery pack 2 is assembled into the frame from the side. When the battery pack 2 is inserted into the placement slot and limited, the latch 5 is actuated to lock the battery pack 2 to prevent it from moving left or right. The latch 5 can be locked by the limiting mechanism 6 to prevent it from rotating, which would affect the stability of the battery pack when it is limited.

[0024] Then press down the clamping handle 9, and the clamping rod 7 moves downward around the support pin 8 under the cam motion trajectory, with the rubber column locked at the front end 10 of the clamping rod 7. When the rubber column contacts the battery pack 2, since the clamping handle 9 has not moved to the lowest point, the rubber column will be compressed to press the top of the battery pack 2, thereby preventing the battery from jumping up and down in the vehicle body.

[0025] In the embodiment of the present utility model, reference Figure 1 As shown, a support plate 3 is installed inside the placement groove, and one end of the top of the support plate 3 is vertically connected to the limiting plate 4.

[0026] It should be noted that: by installing a support plate 3 and vertically connecting a limit plate 4 to the top of the support plate 3, the battery pack 2 can be better moved forward and backward through the guidance of the limit plate 4 when the battery pack 2 is placed, thereby improving the stability during movement. By setting the support plate 3, the battery pack 2 can be better supported, and the bottom of the battery pack 2 can be limited to prevent it from moving up and down due to force.

[0027] In the embodiment of the present utility model, reference Figure 1 As shown, a stretching groove 15 is provided on the side of the battery pack 2 , and the inner wall of the stretching groove 15 is rotatably connected to a stretching rod 16 , and the shape of the stretching rod 16 is U-shaped.

[0028] In the embodiment of the present utility model, reference Figure 1 As shown, a stretching tube 17 is sleeved on the outer surface of the stretching rod 16 . The length of the stretching tube 17 is smaller than the length of the stretching rod 16 , and the stretching tube 17 is made of soft material.

[0029] It should be noted that: by setting a U-shaped stretching rod 16, it is convenient to move the battery pack 2 through the stretching rod 16, and by setting a stretching groove 15, when not in use, the stretching rod 16 can be rotated and placed into the stretching groove 15, and by setting a stretching cylinder 17, the stretching cylinder 17 can be used to improve the comfort during movement.

[0030] The working principle of the quick-change battery clamping mechanism for off-road vehicles provided by the utility model is as follows:

[0031] The battery pack 2 is assembled into the frame from the side. When the battery pack 2 is inserted into the placement slot and limited, the latch 5 is activated to lock the battery pack 2 to prevent it from moving left and right. The latch 5 can be locked through the limiting mechanism 6 to prevent it from rotating, which affects the stability of the battery pack when it is limited. Then the clamping handle 9 is pressed down, and the clamping rod 7 moves downward around the support pin 8 under the cam movement trajectory, and the rubber column is locked to the front end 10 of the clamping rod 7. When the rubber column contacts the battery pack 2, since the clamping handle 9 has not moved to the lowest point, the rubber column will be compressed to press the top of the battery pack 2, thereby preventing the battery from jumping up and down in the vehicle body.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
