The embodiment of the utility model provides a button includes thin wall region and thick wall region, realizes the fixed of button through the thick wall region to support the thin wall region, produce the deformation volume through the thin wall region, thereby can realize effectively triggering to the switch part under the exogenic action, and the self-restoring can be realized from taking the restoring force; and the thin-wall area itself or the low-joint arm can trigger the switch component, and compared with a silica gel material, the thin-wall area has good rigidity. Through setting up the thick wall region for the thin wall region has the strong point, can be through the convenient connection of thick wall region and other parts, through thin wall region and thick wall region integrated into one piece, practiced thrift production processes and cost, and the thin wall region is sealed well with the regional connection part of thick wall, provides the basis for waterproof dustproof product of follow-up design.

It is right to the utility model provides a key, the simulation effect of the displacement change when exerting external force is shown in fig. 4 and fig. 5, and wherein, fig. 4 is the displacement change schematic diagram when exerting external force in the regional central region of thin wall, and fig. 5 is the displacement change schematic diagram when exerting external force in the regional skew central region of thin wall.

It can be seen that the displacement change of the position of the action point of the slave force is the largest, then the displacement gradually decreases towards the periphery, the change of the thickness and the area of the thin-wall area both have an influence on the displacement change, the larger the area of the thin-wall area is, the larger the displacement change is, and the smaller the thickness is, the larger the displacement is. In practice, the pressing area of the thin-wall region can be changed by changing the two parameters, for example, if the pressing area of the thin-wall region is expected to be large, the thickness of the thin-wall region can be selected to be thicker, and if the pressing area of the thin-wall region is expected to be small, the thin-wall region can be selected to be thinner, different relationships between the area and the thickness can be tested through simulation calculation and actual tests, for example, a curve shown in fig. 6 represents a relationship curve between displacement and the diameter of a circular thin-wall region, and under the condition of the same force (1500 g) and the same thin-wall thickness (0.6 mm), the ratio of the area and the thickness of the thin-wall region needs to be larger than 1177.5mm to ensure that the displacement is larger than 0.69mm, because the general light-touch key needs to be triggered by the displacement of about 0.3mm to 0.5mm, on the basis, the thin-wall key needs to be designed to have the displacement larger than the light-touch key displacement, so that the thin-wall key can trigger the light-touch key, otherwise, the experience of the thin-wall key becomes worse, or even the thin-wall key cannot play a role. Particularly, the pressing of the thin-wall key is not limited to be only pressed in the middle, but can be pressed in a certain area, but the detection point of the switch component is fixed, the switch component can be arranged in the middle, and at the moment, if the non-middle part is pressed, as shown in fig. 4 and 5, the ratio of the area to the thickness of the thin wall is larger, so that the requirement of pressing the non-middle part can be met. The design reserves proper thin-wall key deformation allowance, can ensure that the thin-wall key has good hand feeling, can meet the condition of frequently pressing the thin-wall key, can be applied to the service environment of frequently triggering the key, and can reach the pressing service life of the thin-wall key more than 20 ten thousand times through testing.
