Abstract
A button structure includes a circuit board, a first portion, a second portion, and a reinforcement structure. The circuit board has a switch thereon. The first portion is located above the switch. The second portion partially covers the first portion and surrounds the first portion. The reinforcement structure is disposed on the first portion. The reinforcement structure is higher than the first portion in Young's modulus.
Claims19
A button structure comprising:
- a circuit board with a switch thereon;
- a first portion located above the switch, wherein the first portion has a center;
- a second portion partially covering the first portion and surrounding the first portion;
- and
- a reinforcement structure disposed on the first portion, wherein a Young's modulus of the reinforcement structure is higher than a Young's modulus of the first portion;
- wherein, in a transverse direction substantially parallel to the circuit board, a distance between the center of the first portion and a joint between the first portion and the second portion is L1, a distance between the reinforcement structure and the second portion is D1, and the following condition is satisfied:
- 8/3≤L1/D1≤4.
4 more elements
An electronic device, comprising:
- an outer casing having an accommodation space;
- a first portion disposed on the outer casing and located at a side of the accommodation space;
- a circuit board accommodated in the accommodation space, wherein the circuit board has a switch thereon, and the switch corresponds to the first portion;
- and
- a reinforcement structure disposed on the first portion, wherein an orthogonal projection of the reinforcement structure onto a plane in which the circuit board is located does not overlap with an orthogonal projection of the outer casing onto the plane in a direction from the first portion towards the circuit board.
