[0035] refer to Figures 1 to 4The utility model provides a battery compartment assembly 100, which includes a housing 10, an ejection member 20, a lock 40 and a button 50. The housing 10 has an inner cavity 12 for accommodating a battery module, a top opening 14 and a mounting groove 16 provided on a side wall, and the top opening 14 and the mounting groove 16 are both connected to the inner cavity 12. The ejection member 20 is provided at the bottom of the housing 10 and is used to eject the battery module automatically. The lock 40 is provided on the side wall of the housing 10 and can move between a locking position and an unlocking position along a first direction X. The lock 40 moves away from the housing 10 along the first direction X to reach the unlocking position, and the lock 40 moves close to the housing 10 along the first direction X to reach the locking position; when in the locking position, the locking portion 41 (e.g., a locking tongue) of the lock 40 extends into the inner cavity 12 via the mounting groove 16 to engage with the battery module; when in the unlocking position, the locking portion 41 is retracted from the inner cavity 12. The lock member 40 has a receiving groove 42 and a first rolling member 43 located on a side of the receiving groove 42 away from the locking portion 41. The button 50 has a wedge-shaped portion 52, and the button 50 can move along the second direction Y so that the wedge-shaped portion 52 extends into the receiving groove 42 and the inclined surface 53 of the wedge-shaped portion 52 rolls with the first rolling member 43, thereby pushing the lock member 40 to move to the unlocking position.

[0036] The battery module can enter the inner cavity 12 of the housing 10 through the top opening 14 and compress the ejection member 20 (the ejection member 20 may include elastic components such as springs and shrapnel) disposed at the bottom of the housing 10. The battery module placed in the inner cavity 12 is further locked in the inner cavity 12 by engaging with the locking portion 41 of the locking member 40 (e.g., abutting, engaging, etc.).
