[0024] The installation structure 3 includes a connecting plate 301, with connecting plates 301 on both sides. A fixed shaft 302 is movably connected inside the connecting plate 301. The bottom of the fixed shaft 302 is connected to the outside of the mounting frame 1. A limit rod 304 is provided inside the connecting plate 301. A support frame 303 is movably connected to the outer surface of the limit rod 304. The end of the support frame 303 extends to the outside of the connecting plate 301. The support frame 303 is elastically connected to the connecting plate 301 by a spring 305.

[0025] By pulling the connecting plate 301 outward from both sides of the mounting frame 1, and then vertically setting the connecting plate 301 on the outside of the mounting frame 1 through the rotating shaft mechanism 4, and then pulling the support frame 303 outward, the support frame 303 is moved on the outer surface of the limiting rod 304. Thus, the support frame 303 is more convenient to move due to the limitation of the limiting rod 304. At the same time, the support frame 303 is moved to both sides of the lithium battery pack. Due to the elastic force of the second spring 305, the support frame 303 is moved inward and clamped on both sides of the lithium battery pack through the inner side of the support frame 303. This makes it easier for the operator to install the protective plate on the mounting frame 1 on the outside of the lithium battery pack, which brings convenience to the operator's installation and disassembly.

[0026] Example 2

[0027] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the snap-fit ​​assembly 2 includes a connecting rod 201, the outer side of the connecting rod 201 is connected to the outer side of the mounting bracket 1, and the outer surface of the connecting rod 201 is movably connected to the connecting bracket 202.

[0028] The connection between the connecting bracket 202 and the mounting bracket 1 facilitates the insertion of the protective plate into the mounting bracket 1, and the connecting bracket 202 blocks the protective plate fastened to the mounting bracket 1, thereby facilitating the installation and removal of the protective plate.

[0029] Wherein, the connecting frame 202 outside is provided with spring 203, spring 203 the other end is connected with the outside of the mounting frame 1;

[0030] At this time due to spring 203 in extrusion state, will be applied to the connecting frame 202 a downward pressure, through the connecting frame 202 will be fixed on the mounting frame 1, prevent from lithium battery pack down.

[0031] Example 3

[0032] As Figure 4 And Figure 5 As shown, the embodiment includes the features of example 1, the difference between the technical features is that the shaft mechanism 4 includes the mounting block 401, the mounting block 401 bottom extends to the inner cavity of the fixed shaft 302, the mounting block 401 outside is provided with the clamping block 402, the clamping block 402 bottom extends to the inside of the connecting plate 301;

[0033] Pull up the mounting block 401, drive the clamping block 402 from the inside of the connecting plate 301, make it remove the clamping of the connecting plate 301, and then facilitate the connecting plate 301 from the both sides of the mounting frame 1 to open, facilitate the mounting frame 1 as a whole to be installed on the lithium battery pack, when it is needed to replace the protection plate or maintain the protection plate, it is more convenient to disassemble it from the lithium battery pack.

[0034] Wherein, the clamping block 402 top is provided with spring three 403, spring three 403 the other end is connected with the inner wall of the fixed shaft 302;

[0035] Through the elastic force of spring three 403, it is convenient to reset the lifted clamping block 402 and mounting block 401, so that it is convenient to fix the opened connecting plate 301, prevent falling phenomenon from occurring when fixing the protection plate.
