The other end of the connecting slide 305 is fixedly provided with a connecting cross frame 307, and the other side of the connecting cross frame 307 is fixedly provided with a hook lock block 308. A through circular hole is provided at the bottom end of the square block 301 and the interior of the cylindrical column 302. The other side of the locking block 304 is provided with an inclined surface, and the other side of the hook lock block 308 is provided with an inclined surface. A fixed slide 309 is slidingly provided on the top of the connecting cross frame 307, and the fixed slide 309 is fixedly provided on one side of the cooling plate cover 1. The pre-locking components 3 are symmetrically provided on both sides of the cooling plate cover 1, and a card slot is provided on one side of the bottom end of the connecting cross frame 307.

[0023] By combining the cooling plate cover 1 and the battery outer cover 2, the contact top block 404 can enter the square block 301 and the cylindrical column 302. At the same time, the plug lock block 304 is snapped between the contact top block 404 and the round block 403, so as to achieve the effect of fixing the battery outer cover 2, thereby reducing the use of bolts. It can also achieve the fixing effect between the cooling plate cover 1 and the battery outer cover 2, reduce the installation accuracy, and improve the installation and disassembly efficiency.

[0024] Refer to Figure 1 、 Figure 2 and Figure 4 , It further includes a stationary structure 4. The stationary structure 4 includes a fixed connection frame 401, which is arranged in a "C" shape. A return spring 405 is fixedly arranged inside the fixed connection frame 401. A plug-in guide column 402 penetrates and slides through the top end of the fixed connection frame 401. The other end of the return spring 405 is fixedly connected to the plug-in guide column 402. One end of the plug-in guide column 402 is fixedly provided with a承接连柱 (should be translated as "connecting column" here, but the original text might be misspelled), and the other end of the connecting column is fixedly provided with a contact top block 404. A round block 403 slides on the outside of the connecting column. The fixed connection frame 401 is fixedly arranged on one side of the battery outer cover 2. The other end of the contact top block 404 is arranged in an arc shape, and the two end faces of the round block 403 are arranged in a bevel shape.

[0025] Cover the cooling plate cover 1 on the top of the battery outer cover 2, so that the contact top block 404 in the stationary structure 4 can enter the square block 301 and the cylindrical column 302. When the contact top block 404 enters, it will cause the plug lock block 304 in the pre-lock assembly 3 to move away to both sides and drive the connecting slide column 305 to move. At this time, the force-applying spring 306 elongates, and the force-applying spring 306 will provide a restoring force to the plug lock block 304, making it snap between the contact top block 404 and the round block 403, thereby locking the contact top block 404, and further achieving the pre-fixing effect between the cooling plate cover 1 and the battery outer cover 2.

[0026] When unlocking is required, press down the connection handle 507, so that the return lock block �01 (should be "501" here) descends and leaves the card slot. At this time, push up the plug-in guide column 402, so that the return spring 405 elongates. At the same time, the round block 403 will contact the plug lock block 304. At this time, the round block 403 will slide on the outside of the connecting column and cause the plug lock block 304 to move to both sides. The round block 403 contacts the contact top block 404 at this time, and then pull the plug-in guide column 402, so that the round block 403 and the contact top block 404 can descend simultaneously. Since both end faces of the round block 403 are arranged in a bevel shape, the round block 403 will still cause the plug lock block 304 to move to both sides when descending, so as to completely withdraw the contact top block 404 from the square block 301 and the cylindrical column 302, completing the unlocking effect, which is simple and convenient to use.

[0027] Refer to Figure 1 、 Figure 2 and Figure 5, and also includes an auxiliary locking component 5, the auxiliary locking component 5 includes a return lock block 501, the bottom end of the return lock block 501 is fixedly provided with a return spring 503, the outer side of the return lock block 501 is slidably provided with a vertical cover 504, the top side of the return lock block 501 is provided with an inclined surface, the bottom end of the vertical cover 504 is fixedly provided with a bottom connecting frame 506, the bottom connecting frame 506 is fixedly provided on one side of the battery outer cover 2, the return spring 503 is fixedly provided at the inner bottom end of the vertical cover 504, the auxiliary locking component 5 is symmetrically provided on both sides of the stationary structure 4, a sliding short column 502 is fixedly provided on one side of the return lock block 501, a sliding groove 505 is provided on one side of the vertical cover 504, the sliding short column 502 is slidably provided on the inner side of the sliding groove 505, and a connecting handle 507 is fixedly connected between the sliding short columns 502. The interior of the cooling plate cover 1 is provided with a heat dissipation pipe 6.

[0028] Among them, when the force spring 306 moves, the hook lock block 308 will contact the modified return lock block 501 in the auxiliary locking component 5, and make the return lock block 501 drop, and the return spring 503 is compressed. Through the rebound force of the return spring 503, the return lock block 501 enters the card slot, thereby fixing the connecting cross frame 307 and preventing the locking block 304 from loosening. This can reduce the use of bolts, reduce the installation accuracy, facilitate later maintenance, and facilitate installation.

[0029] The working principle of the present invention is as follows: when the cooling plate cover 1 and the battery cover 2 are assembled and combined, the cooling plate cover 1 is placed on the top of the battery cover 2 so that the contact top block 404 in the stationary structure 4 can enter the square block 301 and the cylindrical column 302. When the contact top block 404 enters, the locking blocks 304 in the pre-locking assembly 3 will retreat to both sides and drive the connecting slide column 305 to move. At this time, the force spring 306 is extended, and the force spring 306 provides a spring force to the locking block 304, so that it is stuck between the contact top block 404 and the round block 403, thereby locking the contact top block 404, and then achieving the effect of pre-fixing between the cooling plate cover 1 and the battery cover 2;

[0030] When the force spring 306 moves, the hook lock block 308 contacts the return lock block 501 in the auxiliary lock member 5, causing the return lock block 501 to drop, and the return spring 503 is compressed. The return lock block 501 enters the card slot through the rebound force of the return spring 503, thereby fixing the connecting cross frame 307 and preventing the locking block 304 from loosening. This can reduce the use of bolts, reduce installation accuracy, facilitate later maintenance, and facilitate installation.

[0031] When unlocking is required, the connecting handle 507 is pressed downward, so that the locking block 501 drops out of the slot. At this time, the plug guide post 402 is pushed upward, so that the return spring 405 is extended, and the round block 403 comes into contact with the locking block 304. At this time, the round block 403 will slide on the outside of the connecting post and make the locking block 304 move to both sides. The round block 403 is now in contact with the contact top block 404, and then the plug guide post 402 is pulled so that the round block 403 and the contact top block 404 can drop at the same time. Since both end surfaces of the round block 403 are inclined, the round block 403 will still make the locking block 304 move to both sides when it drops, thereby completely withdrawing the contact top block 404 from the square block 301 and the cylindrical column 302, completing the unlocking effect. It is simple and convenient to use.

[0032] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
