Description

Button assembly

The present invention relates to a button assembly, and more particularly to a modular button assembly.

The conventional rocker component includes a top cover and a pressure sensor. The pressure sensor is usually transmitted through a pressure element sensor or a flexible printed circuit (FPC), that is, a finger. The greater the force of the pressure, the larger the pressing area, and the FPC will sense and convert to a number and convert it to the value of the pressing force. The top cover has a button, and a pressure sensor is installed under the top cover during assembly. When the user uses it, the button will be pressed, and the button will first contact the upper surface of the pressure sensor downward, and then press the pressure sensor downward to complete the pressing of the button.

However, in order to introduce a pressure sensor of a foam soft material, the pressure sensor of the foam soft material has strong sensing sensitivity. Therefore, in the above configuration, it is easily affected by the cumulative tolerance between the structures, resulting in an excessive variation in the value at the time of pressing. And if the button is faulty, it is difficult to distinguish whether it is caused by a pressure sensor or other structure, and it is not easy to replace.

Therefore, it is necessary to provide a modular button assembly that allows the foam soft material pressure sensor to have less cumulative tolerance when used, and can be easily detected and replaced in the rocker member.

The purpose of this creation is to provide a button assembly that can be modularized.

In order to achieve the above object, the present invention discloses a button assembly, which is mounted on a rocker member, the button assembly includes a base, a pressure sensor and a key cap; the base has a receiving groove in the middle thereof. One side of the base has a lower pivoting portion formed to protrude outwardly, and the other side of the base has a lower movable portion formed to protrude outward; the pressure sensor is mounted on the base The keycap covers the pressure sensor, the lower surface of the keycap has a contact portion, and the contact portion is in contact with a soft pressure sensor, the key cap One side includes an upper pivoting portion formed to protrude outwardly, and the upper pivoting portion and the lower pivoting portion are fixedly combined to form a pivoting portion capable of rotating the upper pivotal portion, and the other side of the keycap The upper movable portion is formed by an outwardly protruding portion, and the upper movable portion and the lower movable portion are combined into a movable portion, and the upper movable portion of the movable portion can move up and down in the lower movable portion.

According to the above, the pivoting portion and the movable portion are disposed between the base, the pressure sensor and the keycap to form a pressable button structure, so that the creative button assembly is modularized. When the user presses the creation button assembly, the pressure can be transmitted directly to the pressure sensor through the keycap, and the structure has less cumulative tolerance than the prior art. Its modular structure can also be flexibly assembled or replaced in other vehicles.
