An aluminum busbar is located at the other end of the battery module. A second cover plate is located at the other end of the aluminum busbar. A first cover plate is located at the other end of the second cover plate. A spring-loaded latch body is located outside the limiting plates. A spring-loaded latch hook that cooperates with the spring-loaded latch body structure is located at one end of the first cover plate. Several spring-loaded telescopic pins are located at the end of the first cover plate near the second cover plate. One end of each spring-loaded telescopic pin is fixed to the first cover plate, and the other end presses against the second cover plate or the aluminum busbar.

[0004] In the above solution, the second cover plate is positioned by the limiting plate and the limiting groove, and then it is placed on the battery module. The first cover plate is then positioned by the opening on the first cover plate and the first positioning pin, and the second positioning pin is positioned by the opening on the second cover plate. The first cover plate is then closed, and finally the spring buckle body is fastened to the spring buckle hook. This results in the following disadvantage: when using this device, the cover plate needs to be positioned and disassembled multiple times every time the battery module is replaced. Utility Model Content

[0005] The purpose of this invention is to provide a welding device for energy storage battery modules, so as to solve the problem that the device requires multiple positioning and disassembly / removal of the cover plate each time the battery module is replaced.

Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a welding device for an energy storage battery module includes a placement plate 1, which is disposed on the bottom surface of the battery module body 2. Two limiting plates 3 are fixed to the top surface of the placement plate 1. A mounting base 4 is fixed to the top surface of the left limiting plate 3. A mounting block 5 is rotatably disposed inside the mounting base 4. A lower cover plate 6 is fixed to the right side of the mounting block 5. A plurality of drainage holes 7 are opened on the top surface of the lower cover plate 6. Aluminum strips 8 are disposed in the drainage holes 7 respectively. A support base 9 is fixed to the top surface of the placement plate 1. A support block 10 is rotatably disposed inside the support base 9. An upper cover plate 11 is fixed to the front side of the support block 10. The top surface of the upper cover plate 11... Several welding holes 12 are provided to match the positions of the aluminum strip 8. A fixing box 13 is fixed to the top surface of the placement plate 1. An L-shaped plate 14 is fixed to the front side of the upper cover plate 11. The bottom end of the L-shaped plate 14 is detachably set in the fixing box 13. A fixing groove 15 is provided on the front side of the L-shaped plate 14. A fixing hole 16 is provided on the front side of the fixing box 13. A fixing post 17 is slidably inserted into the fixing hole 16. The fixing post 17 is slidably inserted into the fixing groove 15. A stop block 18 is fixed to the front end of the fixing post 17. A first spring 19 is fixed between the stop block 18 and the fixing box 13. The first spring 19 is wrapped around the fixing post 17.

[0023] In use, the operator first places the battery module body 2 on the top surface of the placement plate 1. At this time, the two limiting plates 3 can limit the left and right sides of the battery module body 2. Then, the operator rotates the lower cover plate 6 on the left limiting plate 3, so that the mounting block 5 rotates inside the mounting base 4, and the lower cover plate 6 covers the battery module body 2. Then, several aluminum strips 8 are placed into several drainage holes 7 respectively. Next, the stop block 18 is pulled forward. At this time, the first spring 19 is in a stretched state. Then, the upper cover plate 11 is rotated, so that the support block 10 rotates inside the support base 9, and the upper cover... The upper cover plate 11 is placed on the lower cover plate 6. Then, the stop block 18 is released, and the fixing post 17 is automatically reset by the first spring 19, allowing it to slide into the fixing groove 15, thus fixing the upper cover plate 11. Then, in conjunction with external welding equipment, the aluminum busbar 8 and the battery module body 2 are welded together. When subsequent welding of the battery module body 2 is required, simply pull the stop block 18 to disengage the fixing post 17 from the fixing groove 15, rotate and open the upper cover plate 11 and the lower cover plate 6 in sequence, remove the welded battery module body 2, and place the new battery module body 2 on the placement plate 1. Repeat the above steps. By using the placement plate 1, the limiting plate 3, the mounting base 4, the mounting block 5, the lower cover plate 6, the extrusion hole 7, the support base 9, the support block 10, the upper cover plate 11, and the welding hole 12 together, the multiple positioning and frequent disassembly and assembly of the cover plate can be reduced, thus improving assembly efficiency.

[0024] like Figures 1-4 As shown, both sides of the outer wall of the mounting base 4 and the support base 9 are provided with rotating holes 20, and both sides of the outer wall of the mounting block 5 and the support block 10 are provided with mounting grooves 21. A second spring 22 is fixed in each of the two mounting grooves 21, and a rotating column 23 is fixed at the outer end of each of the two second springs 22. The two rotating columns 23 are slidably inserted into the two rotating holes 20.

[0025] In use, when the operator needs to disassemble the lower cover plate 6 or the upper cover plate 11, simply press the two rotating columns 23 into the two mounting slots 21 respectively. At this time, the second spring 22 is in a compressed state, causing the rotating columns 23 on the mounting block 5 or the support block 10 to disengage from the rotating holes 20 on the mounting base 4 or the support base 9, thus disassembling the mounting block 5 or the support block 10 and completing the disassembly of the lower cover plate 6 or the upper cover plate 11. Conversely, when the operator needs to install the lower cover plate 6 or the upper cover plate 11, simply press the rotating columns 23 on the mounting block 5 or the support block 10 inward. At this time, the second spring 22 is in a compressed state. Then, place the mounting block 5 or the support block 10 in the mounting base 4 and the support base 9. The second spring 22 can automatically reset the rotating columns 23 and slide them into the rotating holes 20, thus completing the installation of the lower cover plate 6 or the upper cover plate 11. This facilitates the operator to quickly disassemble and install the lower cover plate 6 or the upper cover plate 11 for maintenance or replacement.

[0026] like Figures 1-3 As shown, several spring telescopic pins 24 are fixed on the bottom surface of the upper cover plate 11, and the several spring telescopic pins 24 are located on the outside of the welding hole 12 respectively.

[0027] During use, when the operator rotates the upper cover plate 11 to cover the lower cover plate 6, the spring telescopic pins 24, located on the outside of the welding holes 12, will extend into the drain holes 7 on the lower cover plate 6 as the upper cover plate 11 closes. During the extension process, the spring telescopic pins 24 will adaptively adjust according to the position and height of the aluminum strip 8. Through the elastic action of the spring, the aluminum strip 8 placed in the drain holes 7 is pressed and fixed, which can effectively prevent the aluminum strip 8 from shifting or shaking during the welding process and improve stability.

[0028] like Figure 1 and Figure 2 As shown, several limiting blocks 25 are fixed on the top surface of the placement plate 1, and mounting plates 26 are fixed on the left and right sides of the placement plate 1 respectively. Two mounting holes 27 are opened on the top surface of the two mounting plates 26 respectively.

[0029] During use, when the operator places the battery module body 2 on the top surface of the placement plate 1, the limiting blocks 25 are located on the front and rear sides of the battery module body 2, respectively. After the battery module body 2 is in place, the limiting blocks 25 will limit and block the front and rear sides of the battery module body 2, preventing the battery module body 2 from moving back and forth on the placement plate 1, further enhancing the stability of the battery module body 2 on the placement plate 1. When the operator needs to install and fix the entire device at the required work position, the mounting plates 26 fixed on the left and right sides of the placement plate 1 provide the installation base. The operator only needs to use appropriate bolts and other fasteners to firmly install the device at the work position through the two mounting holes 27 opened on the top surface of the mounting plate 26.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
