The battery cell 100 is built into the first shell 200, and a bottom shell 210 is provided at one end of the first shell 200. The bottom shell 210 is electrically connected to the first shell 200, and the bottom shell 210 is electrically connected to the battery cell 100. The circuit main board 500 is built into the second shell 300, and the first shell 200 is electrically connected to the second shell 300. The first electrode spring 540 electrically connects the battery cell 100 to the circuit main board 500, and the second electrode spring 550 electrically connects the second shell 300 to the circuit main board 500. The circuit main board 500 is installed in the fixed sleeve 400, and the circuit main board 500 divides the internal space of the fixed sleeve 400 into a first space and a second space, and a charging interface 510 is provided in the first space.

[0035] The first shell 200 is made of steel with good electrical conductivity. The first shell 200 is cylindrical. The inner diameter of the first shell 200 matches the diameter of the battery cell 100, and the length of the first shell 200 is slightly larger than the length of the battery cell 100. A bottom shell 210 is provided at one end of the first shell 200 away from the second shell 300. The bottom shell 210 is integrally formed with the first shell 200. The bottom shell 210 is made of a metal material with good electrical conductivity, and the bottom shell 210 is disc-shaped as a whole.

[0036] The battery cell 100 is cylindrical and fixedly assembled in the first shell 200, and the negative electrode of the battery cell 100 faces the bottom shell 210, and the positive electrode of the battery cell 100 faces the second shell 300. The bottom shell 210 is provided with a first protrusion 211 and a second protrusion 212. The first protrusion 211 and the second protrusion 212 are both circular and protrude from the bottom shell 210 toward the battery cell 100. The diameter of the first protrusion 211 is larger than that of the second protrusion. The second convex portion 212 is located at the center of the first convex portion 211, and the first convex portion 211 and the second convex portion 212 are concentrically arranged. In the actual assembly process, the second convex portion 212 will conflict with the negative electrode of the battery cell 100, so that the bottom shell 210 is electrically connected to the battery cell 100. Since the first shell 200 and the bottom shell 210 are integrally formed, the first shell 200, the bottom shell 210, and the battery cell 100 are electrically connected.

[0037] The second shell 300 is arranged at one end of the first shell 200 away from the bottom shell 210. The second shell 300 is made of steel with good conductive properties as a whole. The second shell 300 is cylindrical. The diameter of the second shell 300 matches the diameter of the first shell 200. The second shell 300 is concentrically arranged with the first shell 200, and the second shell 300 and the first shell 200 are fixedly connected by a circumferential welding process, so that the second shell 300 and the first shell 200 are electrically connected.

[0038] The steel shell mobile power supply also includes a fixed sleeve 400, which is a hollow cylinder with one side open. The diameter of the fixed sleeve 400 is slightly smaller than the inner diameter of the second shell 300. The fixed sleeve 400 is fixedly assembled inside the second shell 300, and the fixed sleeve 400 is concentrically arranged with the second shell 300. A limiting ring 310 is provided at one end of the second shell 300 away from the first shell 200. The limiting ring 310 is in a circular ring shape, and the limiting ring 310 is integrally formed with the second shell 300. In the actual assembly process, the fixed sleeve 400 conflicts with the limiting ring 310 to determine the position of the fixed sleeve 400.

[0039] The circuit main board 500 is roughly in the shape of a rectangular plate. The width of the circuit main board 500 is slightly smaller than the inner diameter of the fixed sleeve 400. A first fixing bar 410 and a second fixing bar 420 are provided inside the fixed sleeve 400. The first fixing bar 410 and the second fixing bar 420 are both integrally formed with the fixed sleeve 400. There are two first fixing bars 410, and the two first fixing bars 410 are arranged in parallel and spaced apart. There are also two second fixing bars 420, and the two second fixing bars 420 are arranged in parallel and spaced apart. The spacing distance between the two first fixing bars 410 and the two second fixing bars 420 matches the thickness of the circuit main board 500. The circuit main board 500 is inserted between the two first fixing bars 410 and the two second fixing bars 420, so that the position of the circuit main board 500 is fixed, and at this time, the circuit main board 500 divides the internal space of the fixed sleeve 400 into a first space and a second space.

[0040] A charging interface 510 is provided in the first space. The charging interface 510 is fixedly assembled with the circuit main board 500 and electrically connected. An external device can be charged by inserting a plug matching the charging interface 510 into the charging interface 510. In a specific embodiment, the charging interface 510 is a Type-C interface. A silicone gasket is provided on the side of the charging interface 510 close to the fixed sleeve 400. A fixing groove is also provided on the fixed sleeve 400. The shape of the silicone gasket matches the shape of the fixing groove. In the actual assembly process, pressure is applied to the charging interface 510 so that the silicone gasket is embedded in the fixing groove, and the charging interface 510 is pressed by the cover body 600, so that the steel shell mobile power supply has a better waterproof effect.

[0041] A switch controller 520 is provided in the second space. The switch controller is fixedly assembled and electrically connected to the circuit main board 500. The switch controller 520 can control the working state of the steel shell mobile power supply.

[0042] A fixing column 430 is also provided in the second space. The fixing column 430 is integrally formed with the fixing sleeve 400. The fixing column 430 is cylindrical. A threaded hole is provided at the center of the fixing column 430. The steel shell mobile power supply also includes a cover body 600. The cover body 600 includes a cover plate 610. The cover plate 610 is roughly semicircular. A through hole 611 is provided on the cover plate 610. The screw enters the threaded hole through the through hole 611 to fix the cover plate 610 to the opening of the sleeve, so that the cover plate 610 blocks the second space. A notch 530 is also provided on the circuit main board 500. The notch 530 runs through the circuit main board 500. There are two notches 530, which are symmetrically arranged on both sides of the circuit main board 500. The cover body 600 also includes a limiting portion 620. The shape of the limiting portion 620 matches the shape of the notch 530. The limiting portion 620 and the cover plate 610 are integrally formed. The limiting portion 620 is embedded in the notch 530 to limit the cover body 600.

[0043] Various electronic components are also provided on the circuit main board 500 to realize the charging function of the steel shell mobile power supply. A first electrode spring 540 is provided at one end of the circuit main board 500 close to the first shell 200, and a first fixing portion 541 is provided at one end of the first electrode spring 540 close to the circuit main board 500. The first fixing portion 541 is fixedly assembled on the circuit main board 500 through a welding process. A first bending portion 542 is provided at one end of the first electrode spring 540 away from the circuit main board 500. The first bending portion 542 is arc-shaped as a whole, and the first bending portion 542 and the first fixing portion 541 are integrally formed. In the actual assembly process, the first bending portion 542 conflicts with the positive pole convex column of the battery cell 100, so that the positive pole of the battery cell 100, the first electrode spring 540 and the circuit main board 500 are electrically connected.

[0044] The second electrode spring clip 550 is irregular in shape as a whole. There are four second electrode spring clips 550 in total. Two of the four second electrode spring clips 550 form a group and are respectively arranged on both sides of the circuit main board 500, and the two groups of second electrode spring clips 550 are symmetrical about the first electrode spring clip 540. The second electrode spring clip 550 includes a second fixing portion 551 and a second bending portion 552.

[0045] The second fixing portion 551 and the second bending portion 552 are integrally formed, and the second fixing portion 551 is fixedly assembled on the circuit main board 500 by a welding process. The second bending portion 552 is arc-shaped as a whole, and one end of the second bending portion 552 is connected to the second fixing portion 551, and the other end of the second bending portion 552 is in conflict with the inner wall of the second shell 300, so that the circuit main board 500 is electrically connected to the second shell 300. Since the second shell 300 is electrically connected to the first shell 200, the circuit main board 500 is electrically connected to the first shell 200. Since the first shell 200, the bottom shell 210, and the battery cell 100 are electrically connected, the circuit main board 500 is electrically connected to the negative electrode of the battery cell 100.

[0046] To sum up, the circuit main board 500 is electrically connected to the positive electrode of the battery cell 100 through the first electrode spring 540, and the circuit main board 500 is electrically connected to the negative electrode of the battery cell 100 through the second electrode spring 550, the second shell 300, the first shell 200, and the bottom shell 210, so that the battery cell 100 can supply power to the circuit main board 500.

[0047] The steel shell mobile power supply also includes a soft rubber cover 700, which is made of a silicone material. In another specific embodiment, the soft rubber cover 700 can also be made of other flexible materials with waterproof effects. The soft rubber cover 700 is arranged at one end of the fixed sleeve 400 away from the first shell 200. The shape of the soft rubber cover 700 matches the shape of the fixed sleeve 400. A plurality of limiting columns are provided on the side of the soft rubber cover 700 close to the fixed sleeve 400. A plurality of mounting holes are also provided on the side of the fixed sleeve 400 close to the soft rubber cover 700. The shape of the mounting holes matches the shape of the limiting columns. The limiting columns are embedded in the mounting holes, so that the soft rubber cover 700 and the fixed sleeve 400 are mutually buckled. The soft rubber cover 700 is integrally formed with the fixed sleeve 400 through a two-color injection molding process, so that the soft rubber cover 700 can isolate the internal space of the fixed sleeve 400 from the external environment to enhance the waterproof effect of the steel shell mobile power supply.

[0048] The second space of the fixing sleeve 400 is also filled with glue, and the glue fills up the second space of the fixing sleeve 400, further enhancing the waterproof effect of the steel shell mobile power supply.

[0049] A layer of heat shrink film 800 is further provided on the outer periphery of the first shell 200 and the second shell 300, and the heat shrink film 800 wraps the first shell 200 and the second shell 300. The heat shrink film 800 can be made into different colors to improve the aesthetics of the steel shell mobile power supply. The setting of the heat shrink film 800 can further enhance the waterproof performance of the steel shell mobile power supply.

[0050] To sum up, in the steel shell mobile power provided in the present application, the circuit main board 500 is electrically connected to one end electrode of the battery cell 100 through the first electrode spring 540, and is electrically connected to the other end electrode of the battery cell 100 through the second electrode spring 550, the second shell 300, the first shell 200 and the bottom shell 210. This not only solves the problem of complex production process and poor stability caused by the traditional steel shell mobile power supply generally welding various wires inside the steel shell mobile power supply to form a complete circuit, but also saves wire and welding costs.
