## Abstract

A pressing module includes a housing, an operation panel, a waterproof fixing frame, and an elastic member. The housing includes a first surface, a second surface opposite to the first surface and a slot. The slot passes through the first surface and the second surface. The operation panel is pressibly accommodated in the slot. The waterproof fixing frame is disposed on the second surface of the housing and the operation panel and covers a junction between the second surface and the operation panel. The elastic member is disposed on the waterproof fixing frame. The elastic member includes a fixed side and a movable side that are disposed on two opposite sides. The fixed side is fixed to the second surface, and the movable side is fixed to the operation panel, so that the elastic member can provide an elastic restoring force for the operation panel.

## Claims

### Claim 1

A pressing module, comprising: a housing comprising a first surface, a second surface opposite to the first surface and a slot, wherein the slot passes through the first surface and the second surface; an operation panel pressibly accommodated in the slot; a waterproof fixing frame disposed on the second surface of the housing and the operation panel and covering a junction between the second surface and the operation panel; and an elastic member disposed on the waterproof fixing frame, wherein the elastic member comprises a fixed side and a movable side opposite to the first side, the fixed side is fixed to the second surface, and the movable side is fixed to the operation panel, so that the elastic member is capable of providing an elastic restoring force for the operation panel, wherein a plurality of first protruding posts protrude from the second surface of the housing, a plurality of second protruding posts protrude from the operation panel, and the waterproof fixing frame is sleeved on the first protruding posts and the second protruding posts, wherein a fixing member is sleeved on the first protruding posts and is disposed between the waterproof fixing frame and the elastic member, and wherein a plurality of third protruding posts protrude from the fixing member, the fixed side of the elastic member is sleeved on the first protruding posts, the second protruding posts, and the third protruding posts, and the movable side of the elastic member is sleeved on the second protruding posts.

### Claim 2 (depends on 1)
