When in use, the four corners of the battery 5 are respectively fixed by the four fixing slots 3 to achieve the purpose of fixing the battery 5 in the mounting frame 1, and the first spring rod 20 and the second spring rod 29 have a shockproof effect on the battery 5, and the first spring rod 20, the second spring rod 29, and the third spring rod 25 can be spring damping rods, thereby enhancing their shock absorption effect. The battery 5 and the mounting frame 1 are inaccessible on all sides, and the battery 5 is effectively prevented from vibrating greatly during the driving of the electric vehicle, thereby reducing the loss of the battery 5 and extending the service life of the battery 5. After the battery 5 is installed, the cover plate 12 is covered and the heat dissipation component is used to dissipate heat. At the same time, the battery 5 can be simply and quickly inserted into the four fixed slots 3 through the slidable second spring rod 29, and can be adapted to the installation of batteries 5 of different sizes.

[0028] See also Figure 1In this embodiment, the mounting base plate assembly includes a first base plate 22 and a second base plate 21.

When the battery 5 is installed, the cover plate 12 is covered, and the fixing block 41 abuts against the top of the battery 5 under the drive of the fifth spring rod 4, so as to prevent the battery 5 from longitudinally escaping from the fixed card slot 3, avoid the battery 5 from bouncing upward or even colliding with the cover plate 12 during the driving of the electric vehicle, and further strengthen the fixed installation of the battery 5. The fifth spring rod 4 can be a spring damping rod, so as to enhance its shock absorption effect.

The motor is fixedly installed at the bottom of the cover plate 12. The output shaft of the motor is fixedly connected to a rotating sleeve. A plurality of fan blades 16 are evenly fixedly installed on the rotating sleeve. When in use, the motor is started, and the rotating sleeve is driven to rotate by the output shaft of the motor, thereby driving the fan blades 16 to rotate, achieving the effect of fanning and heat dissipation.

[0036] See also Figure 1 In this embodiment, a handle 15 is fixedly mounted on the cover plate 12 to facilitate the user to take and open the cover plate 12 and take the entire mounting frame.

[0037] The specific usage method of this embodiment is as follows:

[0038] When in use, first remove the cover plate 12 and place the battery 5 into the four fixed card slots 3. At the same time, the distance between the first bottom plate 22 and the second bottom plate 21 is adjusted by the cooperation of the sliding rod 221 and the first sliding slot 211. The cooperation of the sliding seat 28 and the second sliding slot 26 moves the distance between the fixed card slot 3 on one side and the fixed card slot 3 on the other side, thereby achieving the effect of adjusting the distance between the four fixed card slots 3 to adapt to the installation of batteries 5 of different sizes.

[0039] After the battery 5 is installed, the cover 12 is placed on the third limiting ring 14, and then the limiting plate 13 is rotated to rotate the four limiting plates 13 onto the cover 12, so that the cover 12 is clamped between the third limiting ring 14 and the limiting plate 13, thereby fixing the cover 12.

[0040] When the electric vehicle is running, the motor is started, and the output shaft of the motor drives the rotating sleeve to rotate, thereby driving the fan blades 16 to rotate, thereby achieving the effect of fanning and heat dissipation.
