Description

Technical Field

[0001] This utility model relates to the field of battery module technology, and in particular to a flat solar street light lithium battery module. Background Technology

[0002] Solar streetlights can generate and store electricity from sunlight, and then emit light at night. They effectively utilize solar energy, have energy-saving and environmentally friendly effects, and are widely used.

[0003] Currently, most solar streetlights use lithium battery modules to store electrical energy. These modules are typically fixed to a frame below the solar panel or integrated with the light source within a housing. Regardless of the installation method, the battery modules are made into flat rectangular structures to effectively utilize installation space. The lithium battery modules currently in widespread use are made by connecting multiple individual cells in series and parallel. These individual cells are typically covered with heat-shrink film or positioned and installed using an outer frame to form the battery body, which is then installed inside the outer housing.

[0004] Currently, regardless of whether heat shrink film is used for wrapping or external frame positioning, the conductive sheets are connected to the positive and negative terminals of the battery by soldering when connecting individual battery components. Direct soldering makes disassembly difficult, especially when using external frame positioning. The external frame will be damaged during the recycling and disassembly of used batteries. In fact, the external frame is in good working condition and can be reused. Disassembling and damaging the external frame will cause unnecessary waste. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please refer to Figure 1-5 The technical solution of this utility model is as follows: a flat solar street light lithium battery module, including an outer frame and a plurality of individual batteries 4 disposed in the outer frame. The outer frame includes an upper frame 1 and a lower frame 2 that are detachably connected. The upper frame 1 and the lower frame 2 are provided with mounting grooves adapted to the individual batteries 4 on their sides that are close to each other. A third conductive element 33 is provided at the bottom of the mounting groove. The third conductive element 33 is in contact with the electrodes of the individual batteries 4 and conducts electricity.

[0025] For details, please refer to Figures 1-8 This application provides a lithium battery module. The outer frame includes an upper frame 1 and a lower frame 2, both of which are rectangular plate structures. The mounting slots include a first mounting slot 16 disposed on the surface of the upper frame 1 and a second mounting slot 22 disposed on the lower frame 2. The first mounting slot 16 and the second mounting slot 22 are arranged in a row. During installation, one end of a single battery cell 4 is inserted into the first mounting slot 16 and the other end is inserted into the second mounting slot 22. Then, the upper frame 1 and the lower frame 2 are connected to install the single battery cell 4 inside the outer frame. (See reference...) Figure 4 , Figure 8A third conductive element 33 is fixedly installed at the bottom of both the first mounting groove 16 and the second mounting groove 22. The third conductive element 33 is preferably made of copper plate. With this arrangement, after the upper frame 1 and the lower frame 2 are installed, the third conductive element 33 installed in the first mounting groove 16 and the second mounting groove 22 makes contact with the two ends of the single battery 4 for conductive cooperation. With this arrangement, when recycling waste batteries in the future, the upper frame 1 and the lower frame 2 can be separated and the single battery 4 can be taken out directly. The upper frame 1 and the lower frame 2 can be reused, thereby improving the utilization rate of the mounting frame.

[0026] Furthermore, as a specific implementation method, refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 The upper frame 1 is provided with a snap-fit ​​hole 15 on one side near the lower frame 2, and a connecting post 20 is provided on the lower frame 2 corresponding to the snap-fit ​​hole 15. The connecting post 20 includes a snap-fit ​​end 201 that snaps into the snap-fit ​​hole 15.

[0027] In one specific implementation, the snap-fit ​​hole 15 is a through hole, and the end of the connecting post 20 is provided with a reduced-diameter intermediate shaft 200. The snap-fit ​​end 201 is provided at the end of the intermediate shaft 200, wherein the radial dimension of the snap-fit ​​end 201 is larger than the radial dimension of the intermediate shaft 200, and the snap-fit ​​end 201 and the intermediate shaft 200 are separated by a clearance slot 202. The intermediate shaft 200 is made of elastic hard plastic. When the upper frame 1 and the lower frame 2 are connected, the snap-fit ​​end 201 is inserted into the snap-fit ​​hole 15. At this time, under the mutual compression of the inner circumferential surface of the snap-fit ​​hole 15 and the outer circumferential surface of the snap-fit ​​end 201, the intermediate shaft will... The 200 undergoes elastic deformation, causing the snap-fit ​​end 201 to bend towards the central clearance seam 202, thus ensuring that the snap-fit ​​end 201 can pass through the snap-fit ​​hole 15. After passing through the snap-fit ​​hole 15, the snap-fit ​​end 201 leaves the inner circumferential surface of the snap-fit ​​hole 15, and the intermediate shaft 200 is inserted into the snap-fit ​​hole 15. The radial dimension of the intermediate shaft 200 is smaller than the radial dimension of the snap-fit ​​hole 15. At this time, under the elastic force of the intermediate shaft 200, the snap-fit ​​end 201 is reset to both sides, so that the snap-fit ​​end 201 is snapped and positioned on the end face of the other end of the snap-fit ​​hole 15, thereby completing the connection between the upper frame 1 and the lower frame 2.

[0028] Furthermore, as a specific implementation, the side wall of the upper frame 1 is provided with a groove 14 that intersects and communicates with the snap-fit ​​hole 15, and the groove 14 can accommodate the snap-fit ​​end 201. This arrangement allows the snap-fit ​​end 201 to extend into the groove 14, where it is shielded and protected to prevent damage from external impacts, thus ensuring effective snap-fit ​​between the upper frame 1 and the lower frame 2.

[0029] Further, refer to Figure 3A flared end 141 is provided at the end of the groove 14. By providing the flared end 141, it is easy to insert the end of the needle-nose pliers into the flared end 141 to clamp the snap-fit ​​end 201, so that the snap-fit ​​end 201 is separated from the snap-fit ​​hole 15, which facilitates the separation of the upper frame 1 and the lower frame 2.

[0030] Furthermore, as a specific implementation, four snap-fit ​​holes 15 are provided, and the four snap-fit ​​holes 15 are symmetrically arranged on both sides of the upper frame 1. This arrangement ensures the uniformity of the snap-fit ​​force received by the upper frame 1 and the lower frame 2.

[0031] Furthermore, as a specific implementation method, refer to Figure 1 , Figure 2 , Figures 4-8 The bottom of the mounting groove is provided with a through hole, and a conductive post is inserted through the through hole. One end of the conductive post is welded to the third conductive component 33, and the other end is provided with a limiting surface 30 that cooperates with the end of the through hole.

[0032] Specifically, in one implementation, when the individual battery 4 is disposed within the outer frame, the electrodes of adjacent rows of individual battery 4 are opposite, thereby facilitating the use of the first conductive element 31 to connect adjacent rows of individual battery 4 in series. At the edge of the individual battery 4, two second conductive elements 32 are respectively used to connect to the two electrodes of the series battery pack. Specifically, the bottom of the first mounting groove 16 is provided with a first through hole 160, and the bottom of the second mounting groove 22 is provided with a second through hole 220. Both the first conductive element 31 and the second conductive element 32 are plate structures, and multiple conductive elements are spaced apart on the surface of the first conductive element 31. The first conductive post 310 and the second conductive element 32 are provided with multiple second conductive posts 320. With this arrangement, the first conductive post 310 of the first conductive element 31 and the second conductive post 320 of the second conductive element 32 pass through the first through hole 160 or the second through hole 220 and come into contact with the third conductive element 33. Then, they are connected by soldering, thereby connecting the third conductive element 33 to the outside. The limiting surface 30 is the plate surface of the first conductive element 31 and the second conductive element 32. With this arrangement, the third conductive element 33 is fixed at the bottom of the first mounting groove 16 and the second mounting groove 22.

[0033] For details, please refer to Figure 1 , Figure 2 The first conductive element 31 includes two parallel and spaced strip conductive plates that are electrically connected. The two strip conductive plates are correspondingly arranged with two adjacent rows of mounting slots. The second conductive element 32 includes a strip conductive plate, and each conductive plate is provided with multiple conductive posts. The conductive plate is made of copper or aluminum plate.

[0034] Furthermore, as a preferred embodiment, a first groove 10 is provided on the side of the upper frame 1 that is far away from the lower frame 2, and a second groove 25 is provided on the side of the lower frame 2 that is far away from the upper frame 1. Notches are provided on the sidewalls of both the first groove 10 and the second groove 25. By setting a first groove 10 on the upper frame 1 and a second groove 25 on the lower frame 2, the first conductive element 31 and the second conductive element 32 can be accommodated in the first groove 10 and the second groove 25, which can protect the first conductive element 31 and the second conductive element 32. A first notch 11 is set on the side wall of the first groove 10 and a second notch is set on the side wall of the second groove 25. After the multiple rows of single cells 4 in the upper frame 1 and the lower frame 2 are connected in series through the first conductive element 31 and the second conductive element 32, the two second conductive elements 32 set in the first groove 10 and the second groove 25 are respectively connected to the positive and negative terminals of the series battery pack. Subsequently, two wires will be used to weld the two second conductive elements 32 respectively. The first notch 11 and the second notch 21 are set to facilitate the laying of wires.

[0035] Furthermore, in a preferred embodiment, the notches on the sidewalls of the first groove 10 and the second groove 25 are located on the same side. By placing the first notch 11 and the second notch 21 on the same side, two wires connected to the two second conductive elements 32 can be led to the same side.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
