Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a disassembly and assembly ejection device, a battery pack and a battery device. Background Art

[0002] The use of infrared thermal imagers is inseparable from the power supply of batteries. At present, the connection and fixing method between the battery compartment and the thermal imager body is mainly to close the battery cover, and the connection method between the battery pack and the thermal imager body is mainly screw or thread connection. These two connection methods have many inconveniences when replacing batteries. The locking method is too cumbersome, which limits the use of thermal imagers in different situations. In order to realize the rapid replacement of battery packs during the use of thermal imagers, a structure that can quickly replace battery packs is needed.

[0003] In addition to the above cumbersome opening methods of the battery pack and the thermal imager body, the opening methods of the battery disassembly and assembly structures on the market are not automated and labor-saving enough. Some need to be opened with the help of a screwdriver tool, and some need to be rotated to unscrew. However, the rotation action is not a labor-saving process and often requires a lot of force to unscrew. Some need to be turned to open. Because the battery pack itself has a certain weight, under various comprehensive factors such as falling and waterproofing, the push button needs to achieve a high degree of stability to prevent it from falling and bouncing open. In addition, due to the short force arm of the hand-pushed push button, a greater push force is required to push it open, which cannot quickly meet user needs and has a poor user experience. Secondly, the existing battery disassembly and assembly structure cannot be applied to the assembly of lithium battery packs of different capacities, cannot form a standard accessory, and has large limitations in use.
