[0026] like Figures 1 to 9 As shown, an irregularly shaped battery power supply module includes an arc-shaped battery casing and a battery cell. The battery casing includes an outer arc plate 10, an inner arc plate 1, an upper end plate 2, and a lower end plate 9. A first end component 3 and a second end component 4 are respectively provided at both ends of the battery casing. An upper battery cell bracket and a lower battery cell bracket are provided inside the battery casing. Both the upper and lower battery cell brackets are provided with a plurality of battery cell positioning grooves 16. The battery cell is fixed between the upper and lower battery cell brackets, and both ends of the battery cell are respectively connected to the battery cell positioning grooves 16. An electrical connector 5 is provided on the second end component 4. An upper mounting bracket 6 is provided on the upper end plate 2, and a lower mounting bracket 7 is provided on the lower end plate 9.
[0027] In this invention, the battery casing adopts an arc-shaped design. The battery casing is composed of four plate components: an outer arc-shaped plate 10, an inner arc-shaped plate 1, an upper plate 2, and a lower plate 9, which are connected to each other to form a cell mounting space inside the battery casing for installing the battery cells. This casing shape can be highly compatible with the shape characteristics of the arc-shaped mounting space of the drone, and can be directly embedded into the arc-shaped mounting area, significantly improving the matching degree between the battery module and the mounting space. It avoids the installation gap caused by the shape mismatch of traditional regular battery packs, and fundamentally improves the problem of insufficient installation tightness.
[0028] The upper mounting bracket 6 and lower mounting bracket 7 respectively provided on the upper end plate 2 and the lower end plate 9 can form a stable connection with the installation structure of the drone, further enhancing the installation stability of the battery module during the operation of the drone, reducing displacement or loosening caused by factors such as vibration and bumps, and ensuring the continuous and reliable operation of the power supply system.
[0029] In this invention, several cell positioning grooves 16 on the upper and lower cell supports can accurately position and firmly clamp the cells, so that the cells are stably fixed inside the battery casing. This double fixing structure can not only effectively buffer the impact of external shocks on the cells, but also avoid damage caused by collisions and friction due to shaking during use, thus extending the service life of the cells and ensuring the stability of the connection between the cells.
[0030] The upper and lower battery cell brackets are both assembled from several battery cell bracket units 11. Each battery cell bracket unit 11 is provided with a battery cell positioning groove 16. The end of each battery cell bracket unit 11 is provided with a connecting tenon 17, and the connecting tenon 17 is provided with a positioning hole 18. When two adjacent battery cell bracket units 11 are connected, the connecting tenons 17 of the two battery cell bracket units 11 are interlocked and the positioning holes 18 on the two connecting tenons 17 overlap each other, and a positioning pin is inserted into the positioning hole 18.
[0031] In this invention, the upper and lower cell support brackets are assembled from several cell support units 11. The number and combination of these units can be flexibly adjusted according to the arc shape of the battery casing, the number of cells, and their arrangement requirements. Compared to an integral support bracket, this modular design better adapts to the curved surface structure of the arc-shaped battery casing, ensuring that the arrangement of the cell positioning slots 16 perfectly fits the arc-shaped space, further optimizing the rationality of the cell layout within the arc-shaped casing. The connecting tenons 17 at the ends of the cell support units 11 employ an interlocking structure, creating a mechanical locking effect and effectively preventing relative displacement of adjacent units under force or vibration. The cooperation between the positioning holes 18 and the positioning pins further achieves rigid positioning on the basis of interlocking, ensuring the coaxiality and positional accuracy of the overall structure of the assembled bracket, avoiding misalignment of the cell positioning slots 16 due to assembly errors, and ensuring the consistency of cell installation.
[0032] A conductive plate 15 is provided on the battery cell support unit 11. The conductive plate 15 has welding points 20 corresponding to the battery cell, and one end of the battery cell is connected to the welding point 20 on the conductive plate 15. A boss 19 is provided on the battery cell support unit 11, and a positioning groove 21 corresponding to the boss 19 is provided on the conductive plate 15. The boss 19 of the battery cell support unit 11 is embedded in the positioning groove 21 on the conductive plate 15. The conductive plate 15 is connected to an electrical connector 5 via a cable 13. Specifically, the two ends of the battery cell are connected to the welding points 20 on the conductive plate 15 by welding to form a conductive connection, and the conductive plate 15 is connected to the electrical connector 5 via the cable 13 to achieve power transmission. The conductive plate 15 and the battery cell support unit 11 are precisely positioned on the battery cell support unit 11 through the cooperation between the boss 19 and the positioning groove 21. This structure can effectively prevent the conductive plate 15 from shifting or deviating during installation or use, ensuring the correspondence accuracy between the welding point 20 and the battery cell, ensuring the accurate welding position of the battery cell, and further improving the reliability of the electrical connection. In addition, the engagement of the boss 19 and the positioning groove 21 can also enhance the tightness of the connection between the conductive plate 15 and the battery cell support unit 11, reduce the relative shaking between the two, and provide a stable support foundation for the conductive plate 15.
[0033] In this embodiment, the conductive plate 15 is made of copper.
[0034] The conductive plate 15 is provided with a connecting tab 22, which is connected to the cable 13.
[0035] Furthermore, a support column 12 is provided between the upper end plate 2 and the lower end plate 9, and the upper mounting bracket 6 is connected to the position of the support column 12 on the upper end plate 2; the lower mounting bracket 7 is connected to the position of the support column 12 on the lower end plate 9.
[0036] A shock-absorbing pad 8 is installed on the lower mounting bracket 7. The shock-absorbing pad 8 is made of rubber. During flight, especially during takeoff, landing, or when encountering turbulence, the drone will generate vibrations of varying degrees. By installing the shock-absorbing pad 8, which has its own elastic deformation capability, it can absorb and buffer the impact force generated by these vibrations, reducing the transmission of vibration to the inside of the battery module. This can effectively prevent internal components such as battery cells, conductive plates 15, and electrical connectors 5 from becoming loose, having poor contact, or suffering structural damage due to long-term vibration and impact, thus ensuring the structural integrity and electrical performance stability of the battery module.
[0037] The irregularly shaped battery power supply module of this application is used in the field of drones.
[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
