[0041] The utility model will be described in further detail in connection with the drawings. These drawings are all simplified schematic diagrams, and only schematically show the basic structure of the utility model, and thus only show the components related to the utility model. In the description of the utility model, it should be understood that, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0042] Referring to Figures 1 to 2 The replaceable battery structure of the embodiment of the utility model, comprising battery body 2 and connecting structure 1, the connecting structure 1 is arranged on battery body 2, and the connecting structure 1 can be elastically connected with the elastic connecting sheet of the corresponding product, so as to facilitate the assembly, disassembly and replacement of battery body 2. The connecting structure 1 includes input connecting sheet 11, output connecting sheet 12 and temperature sensing switch 13, wherein the input connecting sheet 11 is matched with the battery to realize electrical connection, one end of the temperature sensing switch 13 is connected with the input connecting sheet 11, and the other end is connected with the output connecting sheet 12, the temperature sensing switch 13 can protect the work of the battery, especially when the battery is in abnormal working state, for example, when the battery is in abnormal use state such as overcharge, short circuit, reverse charge, the temperature sensing switch 13 can hinder the flow of current between the input connecting sheet 11 and the output connecting sheet 12, so as to ensure the limit safety performance of the battery under abnormal use. When the battery is in normal working state, the temperature sensing switch 13 can conduct the input connecting sheet 11 and the output connecting sheet 12, so that the output connecting sheet 12 can stably output current to the product end after contacting the connecting end of the product. Therefore, by connecting the output connecting sheet 12 of the connecting structure 1 with the battery body 2, the assembly, disassembly and replacement of the battery are facilitated, and a temperature sensing switch 13 is arranged between the input connecting sheet 11 and the output connecting sheet 12 of the connecting structure 1, which can ensure that the battery is safer and more reliable during use, disassembly and replacement.

[0043] Specifically, the input connecting piece 11 and the output connecting piece 12 are arranged in a ring structure and formed in an integrated structure. During manufacturing, a semi-finished product is manufactured in advance by using a common stamping process, a patch process, a soldering process, a bonding process, etc., and then the components are stamped, the components are patched, and finally the formed input connecting piece 11 and the output connecting piece 12 are welded. Since the input connecting piece 11 directly contacts the battery, the size of the input connecting piece 11 needs to be adapted to the size of the end face of the battery, and the output connecting piece 12 only needs to be able to contact the connecting end of the product, so the outer diameter of the input connecting piece 11 can be set to be greater than the outer diameter of the output connecting piece 12. In addition, since the temperature sensing switch 13 is arranged between the input connecting piece 11 and the output connecting piece 12, the temperature sensing switch 13 is also arranged in a ring structure, and the outer diameter of the temperature sensing switch 13 is equal to the outer diameter of the output connecting piece 12, so as to ensure that the edge of the temperature sensing switch 13 does not protrude outward after being installed between the input connecting piece 11 and the input connecting piece 11, and since the connecting structure 1 is an integrated structure, the compactness of the structure is improved, and the reliability is high, and the manufacturing process is simple.

[0044] More specifically, when the input connecting piece 11 is assembled with one end face of the battery, the input connecting piece 11 is fixed by a welding jig. During fixing, laser welding is performed on the welding area 111 reserved on the input connecting piece 11, so as to realize the electrical connection between the input connecting piece 11 and the negative electrode of the battery. Since the protruding part of the battery needs to penetrate the input connecting piece 11, the temperature sensing switch 13 and the output connecting piece 12 when the input connecting piece 11, the temperature sensing switch 13 and the output connecting piece 12 are installed on the battery, a through hole is coaxially arranged in the middle of the input connecting piece 11, the temperature sensing switch 13 and the output connecting piece 12, and the diameters of the through holes arranged on the input connecting piece 11, the temperature sensing switch 13 and the output connecting piece 12 are the same, so as to control the gap between the input connecting piece 11, the temperature sensing switch 13 and the output connecting piece 12 after being installed on the battery to be within the same range.

[0045] Referring to Figure 3 The replaceable battery structure of the embodiment of the utility model further includes an injection molding part 3 and an insulation auxiliary part 4. The injection molding part 3 is arranged at the connection between the connecting structure 1 and the battery body 2. The insulation auxiliary part 4 covers part of the circumferential side of the battery body 2 and covers the other end face of the battery body 2 opposite to the connecting structure 1, so as to play the role of insulation and high-temperature resistance for the battery body 2. In this embodiment, the insulation auxiliary part 4 can adopt a high-temperature insulation adhesive paper 41.

[0046] Referring to Figures 4 to 5Specifically, the injection molding part 3 comprises an inner injection molding piece 31 arranged at the connecting gap between the output connecting piece 12 and the battery body 2 and an outer injection molding piece 32 arranged at the welding area 111 of the input connecting piece 11 and extending to the edge of the outer injection molding piece 32, so that the outer injection molding piece 32 and the inner injection molding piece 31 can cover the circumferential edge of the main input connecting piece 11, the output connecting piece 12 and the upper surface of the battery body 2. After the injection molding part 3 is completely covered, only the output connecting piece 12 is exposed for external power supply. In addition, the injection molding part 3 is formed by low-pressure injection molding. During the molding, the battery body with the connecting structure 1 welded is first positioned by a mold, and then the edge of the connecting structure 1 is low-pressure injection molded to wrap and form the connecting structure 1 and the battery body 2, so that a more reliable connection between the two can be formed. The injection molding part formed by low-pressure injection molding can provide at least three layers of protection (moisture-proof, dust-proof and oxidation-proof) after wrapping the connecting structure 1 and the battery body 2, thereby ensuring the safety of the battery body 2 during use and ensuring the service life thereof. Moreover, the injection molding part 3 formed by low-pressure injection molding between the connecting structure 1 and the battery body 2 can ensure the structural strength of the connecting structure 1 and the battery body 2, so that the overall structure of the final product is more compact, and the space utilization is improved.
