[0032] Related art button batteries all use simple nickel sheets as battery pins to output and count electrical energy. The nickel sheets are welded to the electrical device, and the nickel sheets lack insulation and safety protection on the outside, resulting in poor replaceability and safety. To address these issues, embodiments of the present application provide a battery assembly and electronic device that can improve the replaceability and safety of the battery assembly.

[0033] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-Figure 3 The embodiment of the present application provides a battery assembly, which includes a housing 100 and an electrical connection structure 200 provided on the housing 100. The housing 100 accommodates a battery cell 300, and the electrical connection structure 200 is electrically connected to the positive and negative electrodes of the battery cell 300.

[0036] Among them, the electrical connection structure 200 includes a mounting member 210 and an electrical connection member fixed to the mounting member 210, the mounting member 210 is fixed to the shell 100, and the electrical connection member includes a first electrical connection part and a second electrical connection part; the first electrical connection part is located inside the shell 100 and is electrically connected to the positive and negative poles of the battery cell 300, and the second electrical connection part is located outside the shell 100, and is used to electrically connect to the electrical equipment to output electrical energy to the electrical equipment, and the second electrical connection part includes a plurality of spaced-apart sheet bodies 212; the plurality of spaced-apart sheet bodies define a plurality of spaced-apart slots, and the slots have conductive terminals connected to the first electrical connection part.

[0037] Compared with the solution of simply welding nickel sheets in the related art, the battery assembly of this embodiment can be connected to the electrical equipment in a plug-in manner. Not only is the electrical connection more reliable, but the battery assembly is also easy to electrically plug in and disassemble, thereby improving the replaceability of the battery assembly.

[0038] See also Figure 1-Figure 2 In some embodiments, the electrical connection structure 200 of the present application is also referred to as a blade-type electrical connection structure 200 because the connector is in a sheet-like shape. The conductive terminals are housed within the slots and are not exposed to the outside, thereby enhancing safety during testing and use and effectively preventing short circuits. In some embodiments, the plurality of spaced-apart sheets 212 can be made of an insulating material and formed as a single unit, secured to the mounting member 210.

[0039] The solution of this embodiment has good safety and replaceability, and therefore meets the requirements of "UL2054 Listed". As an independent battery product, it can be sold separately. "UL2054 Listed" specifically means that the product has passed the UL 2054 standard testing and certification of Underwriters Laboratories (UL).

[0040] In some embodiments, the mounting member 210 is a circuit board, which is secured to the housing 100 via a snap-fit structure, such as a slot 113 provided on the housing 100. The edge of the circuit board snaps into the slot 113, securing the circuit board relative to the housing 100. In some embodiments, the circuit board forms at least a portion of one of the side walls of the housing 100. Specifically, one side of the housing 100 has an opening, and the circuit board is mounted in the opening and can seal the opening, creating a sealed environment within the housing 100. This not only improves the installation stability of the electrical connection structure 200, but also simplifies the structure and reduces material costs.

[0041] See also Figure 2 In some embodiments, the shell 100 is provided with a groove, and the electrical connection structure 200 is embedded and installed in the groove. A plurality of spaced-apart sheet bodies 212 face the outside of the shell 100, and the electrical connection structure 200 does not exceed the outer contour of the shell 100. The groove can be set in the middle of the side of the electrical connection structure 200, and the two sides and the bottom of the electrical connection structure 200 are close to the shell 100 to achieve the positioning of the electrical connection structure 200, which can improve the installation stability of the electrical connection structure 200 and thereby improve the overall reliability of the battery assembly.

[0042] In some embodiments, the slot includes two adjacent plug-in areas, which are respectively located on two adjacent sides of the shell 100. The two plug-in areas are connected to each other, and the two plug-in areas are respectively located on two adjacent sides of the shell 100. In this way, plugging on both sides can improve the plugging stability of the battery assembly on the electronic product.

[0043] In some embodiments, the conductive terminal is arranged on the side of the slot, and the conductive terminal is an elastic conductive terminal. The electrical equipment is provided with a plug-in for inputting electrical energy, and the plug-in can be inserted into the slot. When the plug-in is inserted into the slot, it elastically contacts the conductive terminal in the slot, thereby improving the stability of the electrical connection.

[0044] See also Figure 2-Figure 3 In some embodiments, the housing 100 includes a bottom shell 110 and a top shell 120. The connector seat is installed on the bottom shell 110. The bottom shell 110 has a cavity 112. The battery cell 300 is accommodated in the cavity 112 of the bottom shell 110. An opening is provided on one side of the cavity 112. The battery cell 300 can be placed in the cavity 112 through the opening. The top shell 120 covers the opening to keep the battery cell 300 in a closed environment.

[0045] Gaskets are placed between the battery cell 300 and the inner wall of the housing 100. These gaskets can be made of insulating materials such as foam or rubber. These gaskets help stabilize the battery assembly within the housing 100 and prevent leakage. Specifically, a bottom gasket 130 is placed between the bottom of the battery cell 300 and the bottom wall of the housing. Side gaskets 140 are placed between the sides of the battery cell 300 and the mounting member 210. A top gasket 150 is placed between the top of the battery cell 300 and the top wall.

[0046] The battery cell 300 of this embodiment is a button-type battery cell. The battery cell 300 is roughly cylindrical. The first electrical connection portion includes two oppositely arranged sheet pins 211. The two sheet pins 211 respectively contact the positive and negative poles of the battery cell 300. The two sheet pins 211 are electrically connected to the conductive terminals in the slot. The battery's electrical energy is conducted to the conductive terminals via the sheet pins 211.

[0047] The bottom shell 110 and the top shell 120 are made of fire-resistant plastic and are sealed together. They can be made of the same material, such as PC (Polycarbonate) or ABC (Acrylonitrile Butadiene Styrene), which meet a V-0 fire rating. The housing 100 is flat, with its height being less than its width or length. The bottom shell 110 and the top shell 120 are located on opposite sides of the housing in the height direction.

[0048] In some embodiments, the junction of the bottom shell 110 and the front shell 120 is sealed by an ultrasonic process, which can meet the 250N constant force test requirement of "UL2054 Listed". During the test, the battery assembly of the present application is fully charged according to the prescribed charging method, and then a stable pressure of 250±10N (56±2 pounds of force) is applied to the shell for 5 seconds, applied in turn to the top, bottom and sides of the battery assembly shell. After testing, it was found that the battery assembly did not lose weight, did not explode or catch fire, the shell did not crack to the extent of exposing the battery cells, and the battery assembly did not deflate or leak after being placed for 6 hours. Therefore, the sealing reliability of the bottom shell 110 and the front shell 120 of the present application is strong, and the bottom shell 110 and the front shell 120 are not easy to be disassembled, so that the battery assembly of the present application forms an independent integral structure, which meets the requirements for separate sale.

[0049] See also Figure 1-Figure 2The bottom shell 110 is provided with a connecting boss 111 protruding outward from the surface of the bottom shell 110. The connecting boss 111 and the bottom shell 110 are an integral structure. Two connecting holes 1111 are provided on the connecting boss 111. Connectors such as screws can be used to pass through the connecting holes 1111 to fix the battery assembly to the electronic device. Alternatively, the connecting holes 1111 can be positioning holes to position the battery assembly on the electronic device when installing the battery assembly.
