Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] This utility model discloses a safe lithium battery that is easy to assemble, such as Figure 1-5 As shown, the assembly includes a lithium battery module 2 installed inside the assembly frame 1. The inner bottom surface of the assembly frame 1 has multiple assembly slots 3, and the lithium battery module 2 is placed in the assembly slots 3.

[0023] The assembly frame 1 has heat-conducting plates 4 on both the left and right sides inside, and multiple heat dissipation fins 5 are fixedly installed on one side of each of the two heat-conducting plates 4. The two heat-conducting plates 4 are in contact with the left and right sides of the assembled multiple lithium battery modules 2. Thus, the heat generated by the lithium battery modules 2 during operation will be transferred to the heat dissipation fins 5 through the heat-conducting plates 4, so as to dissipate heat through the heat dissipation fins 5. The assembly frame 1 has moving slots 101 on both the left and right sides inside.

[0024] The inner side of the movable groove 101 is rotatably connected to a first threaded rod 103. The outer surface of the second threaded rod 1014 is provided with two opposite threads. The inner other side of the movable groove 101 is fixedly installed with a first slide rod 102. The outer surface of the first threaded rod 103 is threadedly connected with two fixing bars 104. Both fixing bars 104 are slidably connected to the first slide rod 102. When the operator rotates the second threaded rod 1014, the two fixing bars 104 can move along the first slide rod 102 in opposite directions. Multiple fastening blocks 105 are fixedly installed on the opposite side of the two fixing bars 104.

[0025] Both ends of the heat-conducting plate 4 are fitted with connecting frames 401. Multiple fastening grooves 402 are opened on one side of the outer surface of the two connecting frames 401. When the heat-conducting plate 4 is placed between two fixing strips 104, multiple fastening blocks 105 will be inserted into multiple fastening grooves 402 when the two fixing strips 104 approach each other to clamp and fix the heat-conducting plate 4. The size of the fastening block 105 is the same as the size of the fastening groove 402.

[0026] Furthermore, multiple fastening slots 402 correspond one-to-one with multiple fastening blocks 105. Both sides of the interior of the two connecting frames 401 are fixedly installed with first springs 403, and fastening plates 404 are fixedly installed on opposite ends of the two first springs 403. When the connecting frames 401 are fitted onto the left and right ends of the heat-conducting plate 4, the fastening plates 404 can clamp the two ends of the heat-conducting plate 4 under the elastic action of the first springs 403, thereby facilitating the replacement of the heat-conducting plate 4 and the heat dissipation fins 5.

[0027] The assembly frame 1 has lifting slots 1011 on both the front and rear sides. A second threaded rod 1014 is rotatably connected to one side of the two lifting slots 1011, and a second slide rod 1012 is fixedly installed on the other side of the two lifting slots 1011. A fixing plate 1013 is threadedly connected to the outer surface of the second threaded rod 1014, and the fixing plate 1013 is slidably connected to the second slide rod 1012. By rotating the second threaded rod 1014, the fixing plate 1013 can be raised and lowered along the second slide rod 1012. When the lithium battery module 2 is placed in the assembly slot 3, the fixing plate 1013 descends to contact the lithium battery module 2 and fix the lithium battery module 2.

[0028] Two combination slots 1023 are formed on the left side of the outer surface of the assembly frame 1, and two combination blocks 1021 are fixedly installed on the right side of the outer surface of the assembly frame 1. The two combination blocks 1021 correspond one-to-one with the two combination slots 1023. The top surface of each of the two combination blocks 1021 is provided with a combination hole 1022. The inner top surface of each of the two combination slots 1023 is fixedly installed with a second spring 1024. The bottom surface of each of the two second springs 1024 is fixedly installed with a combination head 1025. The top surface of each of the two combination heads 1025 is fixedly installed with a movable rod 1026. The two movable rods 1026 are... The two movable rods 1026 extend to the outside of the combination groove 1023, and are inserted into the two second springs 1024. Pulling the movable rods 1026 outwards from the combination groove 1023 will cause the combination head 1025 to rise and compress the second springs 1024. Then, the combination block 1021 of the other assembly frame 1 is inserted, and the movable rods 1026 are released. The compressed second springs 1024 will push the combination head 1025 to reset, so that the combination head 1025 is inserted into the combination hole 1022, so as to combine the two assembly frames 1 containing lithium battery modules 2.

[0029] A handle is fixedly installed at one end of the movable lever 1026 that extends to the outside of the combination groove 1023, which can improve the grip feel of the operator when pulling the movable lever 1026 up and down.

[0030] The working principle of this utility model is as follows: Multiple lithium battery modules 2 are placed sequentially in the assembly slot 3, and the second threaded rod 1014 is rotated to lower the fixing plate 1013 to assemble the multiple lithium batteries. The heat-conducting plate 4 is placed between the two fixing bars 104, and the first threaded rod 103 is rotated to clamp the heat-conducting plate 4 with the two fixing bars 104, thus completing the installation of the heat-conducting plate 4. The heat-conducting plate 4 can contact the sides of the multiple lithium battery modules 2, and can transfer the heat of the lithium battery modules 2 to the heat dissipation fins 5, and dissipate the heat through the heat dissipation fins 5 to avoid the temperature from being too high and affecting the normal operation of the assembled lithium battery modules 2.
