Abstract: The present disclosure provides a battery cover catch apparatus. The apparatus includes a battery cover, a slide switch, a catch, and a body. A chute which longitudinally extends is provided on the battery cover. The slide switch is disposed on the chute so as to be able to slide between a first position and a second position. The slide switch includes a block located inside the battery cover. The block is connected to the catch so as to drive the catch to slide synchronously. The catch includes a tongue disposed in a same direction as the extending direction of the chute. The body is provided with a recess correspondingly matching to the tongue. The tongue is engaged with the recess when the slide switch is in a first position, and the tongue is separated from the recess when the slide switch is in a second position.

Abstract: Disclosed is a remote controller. The remote controller comprises a first panel and a second panel. The first panel is connected to the second panel by using a rotating connecting mechanism. The rotating connecting mechanism comprises a fixation base fixed to the first panel, a rotating shaft fixed to the second panel, and a sliding component. The sliding component comprises: an arc-shaped sliding rail disposed in the circumference direction of an outer sidewall of the rotating shaft; elastic pieces disposed on the fixation base in the axial direction of the rotating shaft and provided with circular holes; and rolling balls disposed between the arc-shaped sliding rail and the circular holes in an abutted mode. The arc-shaped sliding rail is fitted to the rolling balls in a sliding mode. Two ends of the arc-shaped sliding rail are higher than the middle of the arc-shaped sliding rail in the axial direction of the rotating shaft.

Abstract: A battery lid lock structure comprises: a battery lid (10), a slide switch (20), a lock (30), and a main body (40). A longitudinally extended slide slot (11) is provided on the battery lid (10); the slide switch (20) is mounted on the slide slot (11) and is slidable back and forth between a first position and a second position, and comprises a lock head (21) located in the inner side of the battery lid (10); the lock head (21) and the lock (30) are connected together to drive the lock (30) to slide synchronously; the lock (30) comprises a bolt (31) extended and disposed in the same direction as the slide slot (11); a slot (41) correspondingly matching the bolt (31) is provided on the main body (40); when the slide switch (20) is at the first position, the bolt (31) and the slot (41) are engaged, when the slide switch (20) is at the second position, the bolt (31) and the slot (41) are separated.
