[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a stacked energy storage lithium battery, including: a support base 1, a connecting frame 2 is provided at the top of the support base 1, and a lithium battery body 3 is provided on the inner side of the connecting frame 2;

[0025] The rear end of the lithium battery body 3 is provided with a wiring adjustment component, which includes a hook 5, and a connecting wire 7 is connected to one side of the hook 5. An adjustment block 8 is provided on the outside of the connecting wire 7. The wiring adjustment component is used to adjust the length of the connecting wire 7 after it is connected.

[0026] Specifically, such as Figure 2 As shown, the rear end of the lithium battery body 3 is connected to a terminal 4, and the hook 5 is connected to the outside of the terminal 4. An adjustment groove 6 is provided on the inside of the hook 5. The connection between the terminals 4 is used for series or parallel connection between the lithium battery bodies 3. The adjustment groove 6 provided on the hook 5 can be on the outside of the terminal 4. The adjustment groove 6 is a combination of a circular groove and a rectangular groove. The circular groove is used for the insertion of the terminal 4, and the rectangular groove is used for limiting the terminal 4.

[0027] Specifically, such as Figure 3 As shown, the top of the adjusting block 8 is connected to the fixing block 9, and the inner side of the fixing block 9 is provided with an elastic clamping plate 10. The fixing block 9 and the elastic clamping plate 10 are symmetrically arranged and can form a clamping effect when close to the connecting line 7, thus having a certain fixing effect.

[0028] Specifically, such as Figure 3 As shown, an extension plate 11 is connected to the bottom front end of the adjusting block 8, a fixed connecting plate 13 is connected to the bottom end of the extension plate 11, and a bottom adjusting plate 12 is connected to the inner side of the fixed connecting plate 13. The extension plate 11 and the fixed connecting plate 13 are guided and connected by an elastic connecting rod, which facilitates the control of the position of the bottom adjusting plate 12 within a certain range. After the connecting line 7 moves, the bottom adjusting plate 12 is positioned by clamping with the adjusting block 8. The holes reserved inside the extension plate 11 and the fixed connecting plate 13 facilitate screw insertion and fixing.

[0029] An installation and adjustment assembly is provided on the outside of the lithium battery body 3. The installation and adjustment assembly includes a slide rail 14, and side positioning strips 15 are provided on both sides of the slide rail 14. A roller 18 is provided at the bottom of the slide rail 14. The installation and adjustment assembly is used for convenient positioning of the lithium battery bodies 3.

[0030] Specifically, such as Figure 4 As shown, the slide rail 14 is connected to the top of the lithium battery body 3, and there are two slide rails 14. The two slide rails 14 are set to match the size of the roller 18, and have a guiding and limiting function for the roller 18.

[0031] Specifically, such as Figure 4 As shown, the side positioning strips 15 are disposed on both sides of the outside of the lithium battery body 3, and the front end of the side positioning strips 15 is connected to the positioning plate 16. The lithium battery body 3 is slidably engaged with the connecting frame 2 through the side positioning strips 15, and is connected and fixed to the connecting frame 2 through the positioning plate 16 after reaching the designated position.

[0032] Specifically, such as Figure 4 As shown, a mounting groove 17 is provided at the bottom of the lithium battery body 3, and a roller 18 is installed inside the mounting groove 17. The roller 18 is hidden inside the mounting groove 17, which can appropriately reduce the support height of the roller 18 and facilitate the positional fit between the lithium battery bodies 3.

[0033] In this embodiment: when connecting the rear terminal 4 of the lithium battery body 3, the terminal 4 is directly snapped into the lug 5. By setting the clamping of the elastic clamp 10 and the positioning of the bottom adjusting plate 12, the length of the connecting wire 7 connecting the two terminals 4 can be controlled. The stability of the connection between the connecting wire 7 and the terminal 4 is improved by positioning the length, and loosening is avoided. Slide rails 14 and rollers 18 are respectively set at the upper and lower ends of the lithium battery body 3, which can be matched and slid together. The side of the lithium battery body 3 is engaged and positioned with the connecting frame 2 by the side positioning strip 15, ensuring the convenience and stability of the connection and installation between the lithium battery bodies 3.

[0034] The specific solution is as follows: During the stacking and installation of energy storage lithium batteries, multiple lithium battery bodies 3 are stacked. The bottom roller 18 is matched with the slide rail 14 at the top of another lithium battery body 3 for sliding guidance. Then, the outer side positioning strip 15 is locked inside the connecting frame 2. After reaching the positioning position, it is locked by the screws connected by the positioning plate 16. Then, when connecting the terminal 4 at the rear end of the lithium battery body 3, the lugs 5 at both ends of the connecting wire 7 are respectively connected to the outer side of the terminal 4 at the rear end of the upper and lower lithium battery bodies 3. Then, the connecting wire 7 is tightened so that the rectangular groove of the lug 5 is locked on the outer side of the terminal 4. The connecting wire 7 is tightened inside the adjusting block 8. One end is positioned by the mutual clamping of the elastic clamp 10, and the other end is first elastically squeezed between the bottom adjusting plate 12 and the adjusting block 8. After adjustment, the extension plate 11 and the fixed connecting plate 13 are connected by screws for positioning. This controls the actual connection length of the connecting wire 7, improves the stability of the connection between the terminal 4 and the lug 5, and improves the stability of the device.
