DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 , describing the specific implementation of this embodiment.

[0029] The embodiment of the present application provides a new hybrid loader battery box and platform fixing device, referring to Figure 1 A new hybrid loader battery box and platform fixing device includes a platform 1, a battery box 2, a front bracket 3 and a rear bracket 4; among them, the platform 1, the front bracket 3 and the rear bracket 4 are all welded with steel plates, which can further improve the supporting capacity and strength of the device.

[0030] Combine Figure 2 and Figure 3 In this embodiment, in order to enhance the strength and supporting capacity of the walkway 1, the side of the walkway 1 used to carry the battery box 2 is further reinforced by welding a diagonal brace 5, and the walkway 1 located on the other side of the battery box 2 is hollowed out to prevent the accumulation of rainwater and the like from affecting the battery box 2, while also effectively reducing the weight of the walkway.

[0031] A shock absorber 6 is provided above the walkway, and the battery box 2 is fixed to the walkway 1 via the shock absorber 6. The top of the shock absorber 6 is bolted to the shock absorber fixing leg 7 of the battery box 2, and the bottom is bolted to the shock absorber fixing welding block 8 of the walkway 1.
