Description

Technical Field

[0001] The utility model relates to the technical field of battery protection boards, and particularly relates to a battery protection board assembly. Background Art

[0002] The battery protection board, as the name implies, the lithium battery protection board is mainly an integrated circuit board that plays a protective role for rechargeable (generally refers to lithium batteries). The reason why lithium batteries (rechargeable type) need to be protected is determined by their own characteristics. Due to the materials of lithium batteries themselves, they cannot be overcharged, over-discharged, over-current, short-circuited, or charged and discharged at ultra-high temperatures. Therefore, lithium battery lithium components always appear with a protection board with a sampling resistor and a current fuse. Existing battery protection boards are usually directly connected to the battery, and no protection structure is installed on the battery protection board to prevent dust, debris, water, etc. from contacting the battery protection board, directly exposing the electronic components on the battery protection board, which is likely to damage the battery protection board and reduce the service life and safety during use of the battery protection board.

[0003] For example, Chinese Patent No. CN209947891U discloses a battery protection board assembly, including a protection box, a box cover and a battery protection board main body. One side of the protection box is open, the box cover is arranged on the side of the protection box with the opening, one side of the box cover is rotatably connected to the protection box, sliding grooves are opened on opposite sides of the inner wall of the protection box, clamping blocks are arranged on opposite sides of the battery protection board main body, the battery protection board main body is arranged in the protection box, and the battery protection board main body is slidably connected to the inner wall of the protection box. An annular groove is arranged at the open end of the protection box, an annular protrusion is arranged on the side of the box cover close to the protection box, a first sealing ring is arranged inside the annular groove, a data socket is arranged at one end of the battery protection board main body close to the box cover, a through hole corresponding to the data socket is opened on the box cover, and the data socket is arranged in the through hole.

[0004] Although the above technical solution solves the corresponding technical problems, the above technical solution still has the following defects:

[0005] The above technical solution is not convenient to take out the battery board protection main body conveniently, thus reducing the flexibility of use. Content of the Utility Model
