[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. With the maturity of electric vehicle technology, lithium batteries are also widely used in the automotive industry.

[0003] Currently, for existing lithium batteries with different types of electrodes, they cannot be completely assembled and placed in a metal box. During transportation and transfer, the lithium batteries are prone to collide with the metal box, resulting in damage to the lithium batteries.

[0004] The reason for this problem is that currently, lithium batteries are mainly stored and transported in metal boxes. Due to the different shapes of lithium batteries with different types of electrodes, some lithium batteries cannot be completely assembled and placed in the metal box, resulting in a gap between the lithium battery and the metal box. During transportation and transfer, the lithium battery is prone to collide with the metal box, resulting in damage to the lithium battery. Content of the Utility Model

The movable plate is slidably connected inside the fixing plate. The trapezoidal plate is slidably connected to the side wall of the movable plate. The two sides of the trapezoidal plate are in contact with the movable plate. The side wall of the movable plate is in contact with the inner wall of the metal box main body. The screw is threadedly connected to the top of the fixing plate and is rotatably connected to the trapezoidal plate.

[0008] In a possible implementation manner, an insulating film is arranged on the inner wall of the metal box main body.

[0009] In a possible implementation manner, a heat dissipation opening is arranged on the side wall of the metal box main body.

[0010] In a possible implementation manner, multiple groups of slide rails are fixedly connected to the inner wall of the metal box main body, and the fixing plate is slidably connected to the side wall of the slide rails.

[0011] In a possible implementation, the movable plate penetrates through both sides of the fixed plate, and the movable plate is fixedly pressed against the inner wall of the metal box body.

[0012] In a possible implementation, a spring is fixedly connected to the side wall of the movable plate, and the end of the spring is fixedly connected to the inside of the fixed plate.

[0013] In a possible implementation, the trapezoidal plate is slidably connected to the inside of the fixed plate, and the screw is rotatably connected to the top of the trapezoidal plate.

[0014] In a possible implementation, a rubber pad is fixedly connected to the side wall of the movable plate, and the side wall of the rubber pad abuts against the inner wall of the metal box body.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] According to Figures 1-4 As shown, a lithium battery metal box body of an embodiment of the present utility model includes a metal box main body 1 and a lithium battery pack disposed inside the metal box main body 1. A fixing component 2 is disposed inside the metal box main body 1. The fixing component 2 includes a fixing plate 201, a movable plate 202, a trapezoidal plate 203, and a screw 204. The fixing plate 201 is slidably connected inside the metal box main body 1. The movable plate 202 is slidably connected inside the fixing plate 201. The trapezoidal plate 203 is slidably connected to the side wall of the movable plate 202. Both sides of the trapezoidal plate 203 abut against the movable plate 202. The side wall of the movable plate 202 abuts against the inner wall of the metal box main body 1. The screw 204 is threadedly connected to the top of the fixing plate 201. The screw 204 is rotatably connected to the trapezoidal plate 203. By disposing a fixing plate 201 that is easy to move inside the metal box main body 1, the fixing plate 201 can clamp and fix the lithium battery pack, avoiding the situation that when the metal box main body 1 moves, the lithium battery pack is likely to move randomly and collide with the metal box main body 1, resulting in damage to the lithium battery pack.

[0024] Furthermore, multiple groups of slide rails 206 are fixedly connected to the inner wall of the metal box body 1. The fixing plate 201 is slidably connected to the side wall of the slide rail 206. The fixing plate 201 is used to fix the lithium battery pack. The lithium battery pack can be fixed by moving the two fixing plates 201. The movable plate 202 penetrates through both sides of the fixing plate 201. The movable plate 202 is pressed and fixed to the inner wall of the metal box body 1. The movable plate 202 is used to fix the fixing plate 201. A spring 205 is fixedly connected to the side wall of the movable plate 202. The end of the spring 205 is fixedly connected to the inside of the fixing plate 201. The spring 205 is used to reset the movable plate 202. By rotating the screw 204 upward, the trapezoidal plate 203 can be driven to move upward. At this time, the movable plate 202 can be contracted and reset into the fixing plate 201 by the pulling force of the spring 205. The trapezoidal plate 203 is slidably connected to the inside of the fixing plate 201. The screw 204 is rotatably connected to the top of the trapezoidal plate 203. The screw 204 is used to move the trapezoidal plate 203. By rotating the screw 204 downward, the trapezoidal plate 203 can be driven to move downward. At this time, the trapezoidal plate 203 will squeeze the two movable plates 202 to move to both sides until the rubber pad 2021 on the side wall of the movable plate 202 is pressed and fixed to the inner wall of the metal box body 1, and the fixing plate 201 can be fixed. A rubber pad 2021 is fixedly connected to the side wall of the movable plate 202. The side wall of the rubber pad 2021 abuts against the inner wall of the metal box body 1. The rubber pad 2021 is used to increase the tightness between the movable plate 202 and the metal box body 1 and can increase the stability of the movable plate 202. An insulating film 101 is provided on the inner wall of the metal box body 1. A heat dissipation port 102 is provided on the side wall of the metal box body 1. The lithium battery pack can be dissipated heat through the heat dissipation port 102.

[0025] When the utility model is in use, first place the lithium battery pack inside the metal box body 1, and then move the two fixing plates 201 towards the lithium battery pack in sequence until the two fixing plates 201 clamp and fix the lithium battery pack. Secondly, rotate the screw 204 downward. The trapezoidal plate 203 can be driven to move downward by the screw 204. At this time, the trapezoidal plate 203 will squeeze the two movable plates 202 to move to both sides until the rubber pad 2021 on the side wall of the movable plate 202 is pressed and fixed to the inner wall of the metal box body 1 to fix the fixing plate 201. Finally, install the box cover and then it can be transferred.

[0026] The above-set lithium battery metal box solves the problem that at present, lithium batteries of different electrode models cannot be completely assembled and placed in the metal box, and during transportation and transfer, the lithium batteries are prone to collide with the metal box, resulting in damage to the lithium batteries.
