[0036] As Figure 1 and Figure 5 shown Figure 1 is a three-dimensional structural schematic diagram of the combined battery; Figure 2 is a cross-sectional schematic diagram of the combined battery; Figure 3 is a disassembled structural schematic diagram of the combined battery; Figure 4 is a three-dimensional structural schematic diagram of the insulating component 3; Figure 5 is a cross-sectional schematic diagram of the insulating component 3. The combined battery of the present application includes a housing 1, an energy storage component 2, an insulating component 3, and a voltage regulating component 4. The energy storage component 2, the insulating component 3, and the voltage regulating component 4 are sequentially arranged in the housing 1. The energy storage component 2 is used for energy storage and discharge. One end of the voltage regulating component 4 passes through the insulating component 3 and abuts against the energy storage component 2, and voltage adjustment and output are performed through the voltage regulating component 4.

[0037] In specific applications, the outer shell 1 has a receiving groove 11, and the energy storage component 2, the insulating component 3, and the voltage regulating component 4 are sequentially arranged in the receiving groove. The energy storage component 2 is electrically connected to the bottom of the receiving groove 11.

[0038] In this embodiment, both ends of the energy storage component 2 have a first polarity end 21 and a second polarity end 22. The first polarity end 21 is electrically connected to one end of the voltage regulating component 4, and the second polarity end 22 is electrically connected to the bottom of the receiving groove 11. Specifically, the energy storage component 2 is a lithium-ion battery, wherein the first polarity end 21 is the positive electrode end and the second polarity end 22 is the negative electrode end.

[0039] Please review Figure 4 and Figure 5 The insulating component 3 has a first limiting hole 31. One end of the voltage regulating component 4 passes through the first limiting hole 31, and after one end of the voltage regulating component 4 passes through the first limiting hole 31, it is electrically connected to the first polarity end 21 of the energy storage component 2. Through the setting of the first limiting hole 31, the voltage regulating component 4 can be fixed to facilitate subsequent processing steps. Further, the insulating component 3 also has an avoidance area 32, and the avoidance area 32 is opened on the outer surface of the insulating component 3. During specific use, a rolling groove treatment can be performed on the outer surface of the outer shell 1, and the rolling groove treatment area will be recessed toward the inside of the receiving groove 11, and this recessed area is located within the avoidance area 32 of the insulating component 3. Furthermore, the insulating component 3 also has a deformation hole 33. The deformation hole 33 is concentrically arranged with the first limiting hole 31 and is communicated with the first limiting hole 31. The first polarity end 21 of the energy storage component 2 is located in the deformation hole 33. One end of the voltage regulating component 4 passes through the first limiting hole 31 and the deformation hole 33 and is electrically connected to the first polarity end 21 of the energy storage component 2. Through the setting of the deformation hole 33, not only can materials be saved and costs be reduced, but also the rolling groove treatment of the outer shell 1 is more convenient. Specifically, the insulating component 3 is made of a soft insulating material, such as plastic.

[0040] Please review Figure 1 and Figure 2, the voltage regulating component 4 includes a circuit board 41 and a conductor 42. The circuit board 41 is located at the opening end of the accommodating groove 11. The conductor 42 is disposed on the side of the circuit board 41 facing the energy storage component 2, and the conductor 42 is electrically connected to the circuit board 41. After one end of the conductor 42 away from the circuit board 41 penetrates through the first limiting hole 31 and the deformation hole 33, it is electrically connected to the first polarity end 21 of the energy storage component 2, thereby realizing the electrical connection between the energy storage component 2 and the circuit board 41. Further, the voltage regulating component 4 further includes an elastic body 43. The elastic body 43 is disposed between the circuit board 41 and the conductor 42, that is, one end of the elastic body 43 is connected to the circuit board 41, and the other end of the elastic body 43 is connected to the conductor 42. At this time, the conductor 42 can be telescopically arranged relative to the circuit board 41, and when the conductor 42 is compressed towards the circuit board 41, it relies on the elastic body 43 for resetting. Specifically, the elastic body 43 is an existing spring. During assembly, the energy storage component 2, the insulating component 3, and the voltage regulating component 4 are sequentially placed in the accommodating groove 11, and then the edge of the slot opening of the accommodating groove 11 is subjected to internal pressure treatment. The internally pressed part abuts against the upper surface of the circuit board 41, thereby fixing the components (energy storage component 2, insulating component 3, voltage regulating component 4) in the accommodating groove 11 and preventing phenomena such as shaking. After assembly, the circuit board 41 is located on the upper surface of the insulating component 3, and the various electronic components on the circuit board 41 are in contact with the upper surface of the insulating component 3. In this way, it can be prevented that after the housing 1 is subjected to the roller groove treatment, the roller groove directly contacts the electronic components on the circuit board 41, avoiding short - circuit phenomena of the electronic components on the circuit board 41.

[0041] Please review Figure 2 and Figure 3 , the combined battery further includes a first metal part 5. The first metal part 5 is disposed at the first polarity end 21 of the energy storage component 2, and the first metal part 5 is electrically connected to the first polarity end 21 of the energy storage component 2. The first metal part 5 is located in the deformation hole 33, and one end of the conductor 42 abuts against the first metal part 5 after penetrating through the first limiting hole 31 and the deformation hole 33; in this embodiment, the first metal part 5 is made of steel, aluminum or copper, and it is a mesh structure, so as to increase the friction between one end of the conductor 42 and the first metal part 5, play an anti - slip role for the conductor 42, and is also beneficial to improving the discharge rate. In another embodiment, the first metal part 5 may further be provided with a second limiting hole (not marked in the figure), and one end of the conductor 42 passes through the second limiting hole and is electrically connected to the first polarity end 21 of the energy storage component 2. By providing the second limiting hole, the stability of the conductor 42 can be improved, and the anti - slip effect can be further enhanced.

[0042] Furthermore, the combined battery further includes a second metal part 6. The second metal part 6 is disposed at the second polarity end 22 of the energy storage component 2, and the second metal part 6 is electrically connected to the second polarity end 22 of the energy storage component 2 and the bottom of the accommodating groove 11. In this embodiment, the second metal part 6 is the same as the first metal part 5, and will not be elaborated here.

[0043] In summary, through the cooperation of the outer shell 1, the energy storage component 2, the insulating component 3 and the voltage regulating component 4, the output voltage of the energy storage component 2 is adjusted through the voltage regulating component 4 so that the output voltage reaches the required value. The voltage regulating component 4 is limited through the first limiting hole 31 to facilitate the assembly of the voltage regulating component 4. Then, the overall structure is wrapped into one by the outer shell 1, so that the structural stability of the combined battery is improved during use and production.
