The wear-resistant block 53 is mounted on the slot 512 and protrudes beyond the battery compartment main body 51 in the thickness direction to abut against the inner wall of the housing 1. The friction between the wear-resistant block 53 and the inner wall of the housing 1 improves the sliding resistance of the battery compartment 5, and prevents the battery compartment main body 51 from slipping out of the housing 1 due to excessive sliding force.

Two baffles 52 are arranged on both sides of the battery case body 51. The baffle plate 52 is plate-shaped and is adapted to the opening 14 of the cabinet 1, so that the size of the outer contour of the baffle plate 52 is identical to the size of the inner contour of the opening 14.

The second shutter 522 can cover the opening 14 as the battery case main body 51 slides.

Of the two baffles 52, the first baffle 521 is relatively close to the deformation portion 42. A first buckle 5211 is protruded from one side surface of the first barrier 521 facing the deformation portion 42, and the first buckle 5211 can be engaged with the second buckle 423. The first catch 5211 extends toward the deformation 42 and away from the opening 14. The battery compartment 5 is fastened and connected with the middle shell 4 by the fastening connection of the second fastener 423 and the first fastener 5211, so that the battery compartment 5 is fixed in the accommodating cavity 13 of the machine shell 1 under the limitation of the middle shell 4, and the sliding of the battery compartment 5 is limited by the middle shell 4, in addition, the second fastener 423 can swing along with the swing of the deformation part 42 to be separated from the first fastener 5211, so that the battery compartment 5 slides without being limited by the middle shell 4, and the battery compartment 5 can be separated from the accommodating cavity 13 from the opening 14.

A plurality of sets of springs 55 are disposed between the first plate 521 and the second plate 522. Each set of springs 55 has two springs 55, and the two springs 55 are a first spring 551 and a second spring 552, respectively, but not limited thereto. The first spring 551 and the second spring 552 are respectively arranged at both sides of the corresponding battery mounting groove 511. The first spring 551 is disposed on the first shutter 521 and close to the circuit board 3. One end of the first spring 551 extends to the first baffle 521 along the direction facing the containing cavity 13 and penetrates through the first baffle 521, so that one end of the first spring 551 is attached to the first baffle 521 and faces the battery installing groove 511, and the first spring 551 can be detachably installed on the first baffle 521. The other end of the first spring 551 extends to a side surface of the first baffle 521 facing the circuit board 3, and is mainly used for butting against the circuit board 3.

The second spring 552 elastically fits on a side surface of the second shutter 522 facing the receiving cavity 13, and is in an open state. When the battery is installed in the battery installation groove 511, two ends of the battery elastically abut against the second spring 552 and the first spring 551, respectively, so that the battery compartment 5 is conducted with the circuit board 3.

The elastic member 54 may be a spring. One end of the elastic member 54 is close to the circuit board 3 and passes through the corresponding via hole 32 to contact and conduct the circuit board 3. The other end of the elastic element 54 extends to the accommodating cavity 13 in an open state and is used for electrically connecting the first spring 551 of the battery compartment 5, so as to conduct the circuit board 3 and the battery compartment 5. When the second latch 423 is connected to the first latch 5211, the elastic member 54 is pressed by the first baffle 521 of the battery compartment 5 to be compressed, and meanwhile, the elastic member 54 is electrically connected to the first spring 551 of the battery compartment 5.

When the second latch 423 is separated from the first latch 5211, the elastic element 54 is transformed from a compressed state to an open state, and provides an elastic driving force to the first baffle 521, so as to drive the battery compartment 5 to separate from the accommodating cavity 13 of the casing 1 from the opening 14 of the casing 1, and the switch button 421 does not slide along with the sliding of the battery compartment 5, thereby effectively avoiding the contact between the switch button 421 and the inner wall of the casing 1, further avoiding the abrasion between the switch button 421 and the inner wall of the casing 1, and improving the extension reliability of the battery compartment 5.
