摘要： The present invention provides a battery device and a working assembly having the battery device. The battery device comprises a locking component, an operation component and a transmission mechanism. The locking component can engage with or disengage from a working device. The operation component is spaced apart from the locking component and can be actuated by an operator. The transmission mechanism is configured to transmit a motion of the operation component to the locking component when the operation component is actuated, and the transmission mechanism comprises at least two connecting rods which are sequentially connected to each other in a force transmission direction. The present invention can satisfy the needs for long-distance transmission of motion between an actuating component and the locking component. In addition, force-exerting and force-receiving components in the force transmission chain all have sufficient rigidity and are not easy to deform and not prone to wobbling, thus ensuring the stability of force transmission and also avoiding the possibility of damage caused by deformation of the force-exerting and force-receiving components under the action of force.

摘要： The present invention provides a housing assembly and a battery pack, and the battery pack can be plugged into a compatible device. The housing assembly comprises a housing for accommodating batteries and a latch mechanism fitted to one end of the housing, which comprises a lug, a bias and an actuator. The lug retractably protrudes along a first direction perpendicular to the plugging direction and can, in the protruding state, cooperate with the locking mechanism of a compatible device to lock the battery pack. The bias can apply a biasing force to keep the lug extended. The actuator is movably arranged in a first direction, and the lug can be retracted and unlocked from the locking structure in response to the operation of the actuator. According to the present invention, the latch mechanism can lock the battery pack relative to the compatible device when it is plugged into the compatible device, thereby forming a stable electrical connection between the battery pack and the compatible device. To remove the battery pack, it is only necessary to operate the actuator in the first direction to complete the unlocking, and the operation method is simple, making it especially suitable for application scenarios with a small installation space.
