Abstract: A panel structure is removably connected with a main housing of an electronic device. The panel structure comprises a panel body, two movable members and at least two elastic members. The panel body comprises two fixing parts; each movable member is movably connected with the panel body, and each movable member comprises a pivoting part and a corresponding fixing part, wherein the two movable members are movably apart from each other in a first axial direction such that each movable member is fixed with each fixing part with each corresponding fixing part, making each pivoting part which moves along with each movable member pivotally connected to the main housing. Each elastic member has two ends respectively connected to the movable members and the panel body.

Abstract: A push button assembly disposed on a cover has a push button hole, and includes a holder, a latch, a resilient member, and pushing bracket. The holder forms a chute with the cover. The holder has an abutting plate and a retaining structure. The abutting plate and the retaining structure are respectively located at first and second ends of the chute. The latch is slidably disposed in the chute and faces the push button hole. The retaining structure can prevent the latch from leaving the chute from the second end. The resilient member is disposed in the chute and compressed between the abutting plate and the latch. The pushing bracket is connected to the latch and extends away from the cover. The disclosure further discloses a chassis applying the push button assembly and an operating method of the chassis.
