[0024] The following is a further detailed description of the present application Figure 1-6 in conjunction with the attached

[0025] The embodiment of the present application discloses a lithium battery with a protection structure. Referring to Figure 1 、 Figure 2 and Figure 3 , a lithium battery with a protection structure includes a protective shell 1. The protective shell 1 includes a shell body 101. A fixed seat 102 is installed in the inner cavity of the shell body 101. A lithium battery body 103 is installed in the inner cavity of the fixed seat 102. A protection mechanism 2 is installed on the front side of the shell body 101;

[0026] The protection mechanism 2 includes a protection cover 201, a support plate 203 and a connection seat 205. The back side of the protection cover 201 is movably connected to the front side of the shell body 101. The bottom of the support plate 203 is fixedly connected to the top of the shell body 101. The top of the connection seat 205 is fixedly connected to the bottom of the shell body 101. A damping telescopic rod 208 is fixedly connected to the back side of the protection cover 201. A shock-absorbing plate 206 is fixedly connected to the back side of the damping telescopic rod 208. The back side of the shock-absorbing plate 206 is attached to the front side of the lithium battery body 103. The material of the shock-absorbing plate 206 is rubber.

[0027] Refer to Figure 3 , shock-absorbing springs 207 are fixedly connected to the four corners of the back side of the protective cover 201. The back side of the shock-absorbing springs 207 is fixedly connected to the front side of the shock-absorbing plate 206. Through the setting of the shock-absorbing springs 207, the shock-absorbing plate 206 is supported, and the vibration effect transmitted from the protective cover 201 to the shock-absorbing plate 206 is reduced, thereby reducing the vibration effect received by the lithium battery body 103.

[0028] Refer to Figure 1 , an elastic clamping block 202 is fixedly connected to the inner cavity of the support plate 203. The inner cavity of the support plate 203 is movably connected to a fixing plate 204. The bottom of the elastic clamping block 202 is attached to the top of the fixing plate 204. The bottom of the fixing plate 204 is fixedly connected to the top of the protective cover 201. Through the setting of the support plate 203, the position of the elastic clamping block 202 is supported, so that the position of the fixing plate 204 is fixed by the elastic clamping block 202, and the protective cover 201 can be stably attached to the surface of the housing 101.

[0029] Refer to Figure 1 and Figure 4 , a fixed shaft 209 is fixedly connected to the inner cavity of the connecting seat 205. The surface of the fixed shaft 209 is movably connected to a movable seat 210. The top of the movable seat 210 is fixedly connected to the bottom of the protective cover 201. Through the setting of the connecting seat 205, the position of the fixed shaft 209 is supported, so that the movable seat 210 can rotate on the surface of the fixed shaft 209 to adjust the position of the protective cover 201, facilitating the removal of the lithium battery body 103 from the inside of the fixed seat 102.

[0030] Refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 , heat dissipation mechanisms 3 are installed on both sides of the inner cavity of the housing 101. The heat dissipation mechanisms 3 include heat dissipation holes 302 and heat dissipation grooves 303. The heat dissipation holes 302 are opened on both sides of the inner cavity of the fixed seat 102, and the heat dissipation grooves 303 are opened on both sides of the inner cavity of the housing 101. One side of the inner cavity of the heat dissipation groove 303 is fixedly connected to a heat dissipation plate 307. A filter groove 306 is opened in the inner cavity of the heat dissipation plate 307. Through the setting of the heat dissipation holes 302, the heat dissipation effect of the lithium battery body 103 is increased. Through the setting of the heat dissipation plate 307, the heat dissipation effect inside the housing 101 is increased. And through the setting of the filter groove 306, the dust carried in the air can be filtered to prevent it from entering the inside of the housing 101.

[0031] Refer to Figure 6On the other side of the inner cavity of the heat dissipation groove 303, there is a movable plate 301 movably connected. On one side of the movable plate 301, there is a connecting rod 310 fixedly connected. On one side of the connecting rod 310, there is a handle 309 fixedly connected. Through the setting of the handle 309, the contact area with the movable plate 301 is increased, thus facilitating the movement of the position of the movable plate 301. Through the setting of the movable plate 301, the heat dissipation area of the heat dissipation plate 307 can be adjusted, so that the heat dissipation effect inside the housing 101 can be adjusted according to different needs.

[0032] Refer to Figure 5 and Figure 6 , on the front side and the back side of the inner cavity of the heat dissipation groove 303, there are fixed grooves 304 opened. Inside the fixed groove 304, there is a guide seat 305 fixedly connected. The material of the guide seat 305 is epoxy resin. Inside the guide seat 305, there is a guide groove 308 fixedly connected. The inner cavity of the guide groove 308 is movably connected with the surface of the movable plate 301. Through the setting of the guide groove 308, the movable plate 301 can move inside the guide seat 305. Thus, through the setting of the guide seat 305, the movement of the movable plate 301 is guided, and the friction force received by the movable plate 301 during the movement is increased, so as to improve the fixing effect of the movable plate 301.

[0033] Working principle: First, place the lithium battery body 103 into the interior of the fixed seat 102. Then, push the protective cover 201 to rotate. The rotation of the protective cover 201 drives the movable seat 210 to rotate on the surface of the fixed shaft 209. During the rotation of the protective cover 201, the shock-absorbing spring 207 and the damping telescopic rod 208 are also driven to rotate. The rotation of the shock-absorbing spring 207 and the damping telescopic rod 208 drives the shock-absorbing plate 206 to rotate until the back side of the shock-absorbing plate 206 fits against the surface of the lithium battery body 103. In this way, the shock transmitted to the lithium battery body 103 can be reduced through the shock-absorbing spring 207 and the damping telescopic rod 208. At the same time, when the shock-absorbing plate 206 is in place, the surface of the fixed plate 204 will be inserted into the interior of the support plate 203, so that the position of the fixed plate 204 is fixed under the limitation of the elastic clamping block 202, preventing the protective cover 201 from detaching from the surface of the housing 101. When the housing 101 is in normal use, the heat dissipation effect inside the housing 101 is improved through the heat dissipation plate 307, and the heat dissipation effect inside the fixed seat 102 is improved through the heat dissipation holes 302. And when it is necessary to adjust the heat dissipation area of the heat dissipation plate 307, hold the handle 309 and move it. The movement of the handle 309 drives the connecting rod 310 to move, and the movement of the connecting rod 310 drives the movable plate 301 to move, thereby adjusting the heat dissipation area of the heat dissipation plate 307. During the movement of the movable plate 301, it will slide inside the guide groove 308, so that the guide seat 305 guides the movement of the movable plate 301, and the friction force received by the movable plate 301 during the movement will be increased, thereby improving the fixing effect of the movable plate 301 and preventing the position of the movable plate 301 from shifting.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
