The horizontal arrangement of the TYPE-C charging port reduces the vertical space occupied by the TYPE-C interface, thereby increasing the size of the battery cell and improving its capacity.

[0004] Another objective of this invention is to provide a No. 7 lithium battery with a horizontal TYPE-C charging port, which achieves conductivity between the battery cell and the charging / discharging protection mainboard through conductive springs and contacts. The structure is simple, easy to manufacture, and facilitates automated production of the product.

The main body has a mounting slot and a horizontally arranged opening. The circuit board is located in the mounting slot, and the type-C interface is mounted on the circuit board and located in the horizontal opening.

[0010] In this application, by arranging the circuit board and type-C interface horizontally, the vertical dimension of the main body can be reduced, so that the entire control module occupies less space in the vertical direction. Under the premise of keeping the housing size unchanged, the space of the mounting cavity can be increased, thereby increasing the size of the battery cell and improving the battery capacity.

[0011] Furthermore, an isolation section is provided between the mounting slot and the opening, and a snap-fit ​​hole is provided on the isolation section. One end of the circuit board passes through the snap-fit ​​hole and connects to the type-C interface, thereby enabling the circuit board to be fixed.

[0012] Furthermore, the housing is provided with clearance holes corresponding to the location of the type-C interface.

[0013] Furthermore, the main body has a positioning buckle, and the side wall of the mounting position has a positioning hole, and the positioning buckle is engaged in the positioning hole.

[0014] Furthermore, the control module includes a positive terminal and a conductive component. The housing is made of a conductive metal material, and the bottom of the housing has a negative terminal. The positive terminal passes through the main body and is connected to the circuit board. The circuit board is electrically connected to the battery cell through the conductive component, and the housing is connected to the circuit board through the conductive component.

[0015] Furthermore, the battery cell includes a battery cell body, on which a positive electrode tab and a negative electrode tab are provided. The conductive component includes an FPC sheet and a conductive spring. A first electrical connection portion and a second electrical connection portion are provided on the periphery of the FPC sheet. One end of the conductive spring is connected to the FPC sheet, and the other end is connected to the positive electrode tab. The first electrical connection portion is connected to the circuit board, and the second electrical connection portion is connected to the housing.

[0016] The advantage of this invention compared to existing technologies is that:

[0017] First, by arranging the circuit board and Type-C interface horizontally, the vertical dimension of the main body can be reduced, making the entire control module occupy less space in the vertical direction. Under the premise of keeping the housing size unchanged, the space of the mounting cavity can be increased, thereby increasing the size of the battery cell and improving the battery capacity.

[0018] Secondly, the conductive connection between the battery cell and the circuit board is achieved through FPC sheets and conductive springs, which is simple in structure, convenient to produce, and facilitates the automated production of the product. Attached Figure Description

[0025] See Figure 1-3 As shown, this embodiment provides a AAA lithium battery with a horizontal TYPE-C charging port, comprising:

[0026] The housing 1 has a mounting cavity 11 and a mounting position 12, wherein the mounting position 12 is located above the mounting cavity 11;

[0027] Battery cell 2 is disposed within the mounting cavity 11;

[0028] The control module 3, located on the mounting position 12, includes a main body 31, a horizontally arranged circuit board 32, and a horizontally arranged type-C interface 33. The main body 31 has a mounting groove 311 and a horizontally arranged opening 312. The opening 312 is adapted to the shape of the type-C interface 33. The circuit board 32 is located in the mounting groove 311, and the type-C interface 33 is mounted on the circuit board 32 and located in the opening 312.

[0029] In this application, the main body 31 is made of plastic material. During production, the main body 31, circuit board 32, and type-C interface 33 are injection molded into one piece. In the main body 31, by opening a horizontally arranged mounting groove 311 and an opening 312, the circuit board 32 and type-C interface 33 are arranged horizontally, thereby reducing the vertical dimension of the main body 31. This makes the space occupied by the entire control module 3 in the vertical direction smaller. Under the premise that the size of the housing 1 remains unchanged, the space of the mounting cavity 11 can be increased, thereby increasing the size of the battery cell 2 and improving the battery capacity.

[0030] Furthermore, an isolation portion 315 is provided between the mounting groove 311 and the opening 312, and a snap-fit ​​hole 313 is provided on the isolation portion 315.

[0031] Furthermore, the housing 1 is provided with a clearance hole 13 corresponding to the position of the type-C interface 33, so that the charging cable can easily pass through the housing 1 and connect to the type-C interface 33.

[0032] Furthermore, the main body 31 has a positioning buckle 314, and the side wall of the mounting position 12 has a positioning hole 14. The positioning buckle 314 is snapped into the positioning hole 14, thereby making it easy to snap and fix the main body 31 onto the mounting position 12 of the housing 1.

[0033] Furthermore, the control module 3 includes a positive terminal 34 and a conductive component. The housing 1 is made of a metal material with conductive properties. The bottom of the housing 1 has a negative terminal 15. The positive terminal 34 passes through the main body 31 and is connected to the circuit board 32. The circuit board 32 is electrically connected to the battery cell 2 through the conductive component. The housing 1 is connected to the circuit board 32 through the conductive component.

[0034] Furthermore, the battery cell 2 includes a battery cell body 21, on which a positive electrode tab 22 and a negative electrode tab 23 are provided. The conductive component includes an FPC sheet 35 and a conductive spring 36. A first electrical connection portion 37 and a second electrical connection portion 38 are provided on the periphery of the FPC sheet 35. One end of the conductive spring 36 is connected to the FPC sheet 35, and the other end is connected to the positive electrode tab 22. The first electrical connection portion 37 is attached to the bottom surface of the circuit board 32, and the second electrical connection portion 38 is attached to the inner wall of the housing 1.

[0035] In use, the positive terminal 34 serves as the positive terminal of the battery, and the negative terminal 15 serves as the negative terminal of the battery. The positive terminal tab 22 of the battery cell is connected to the circuit board 32 through the conductive spring 36 and the FPC sheet 35, and the negative terminal tab 23 is connected to the circuit board 32 through the housing 1 and the FPC sheet 35. This not only ensures the elastic conductive connection between the battery cell 2 and the circuit board 32, but also simplifies the conductive structure between the battery cell 2 and the circuit board 32, making assembly and production easier, and thus facilitating the automated production of the battery.
