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, and the base has a receiving groove in the middle thereof. One side of the base has a lower fixing portion which is formed to protrude outwardly, and the other side of the base has a lower movable portion which is formed to protrude outwardly, and the pressure sensor is installed in the receiving groove of the base The keycap covers the pressure sensor, and the lower surface of the keycap has a contact portion that is in contact with an upper surface of the soft material sensor, the key cap One side has an upper fixing portion formed to protrude outwardly, and the upper fixing portion and the lower fixing portion are combined and fixed into an inactive fixing portion, and the other side of the key cap has an upward movement formed by outwardly protruding 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 be moved up and down.

According to the above, the fixed 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 reaches the module. Chemical.

The upper fixing portion 32 includes a first upper extending portion 33 which is formed to protrude outward from a side of the keycap 3, and the first upper extending portion 33 is provided corresponding to the first lower extending portion 13. The first upper fixing portion 33 defines a first upper fixing hole 331 , and the first upper fixing hole 331 is corresponding to the first lower fixing hole 132 . The other side of the keycap 3 has an upper movable portion 34 formed to protrude outwardly, and the upper movable portion 34 and the lower movable portion 14 are combined into a movable portion, and the upper movable portion 34 of the movable portion Can move up and down. The upper movable portion 34 has a second upper extending portion 35 which is formed to protrude outward from the other side of the keycap 3. The second upper extending portion 35 is corresponding to the second lower extending portion 15 . . A second upper fixing hole 351 is defined in the second upper extending portion 351 , and the second upper fixing hole 351 is disposed on the second lower protruding base 151 . The upper movable portion 34 can be moved up and down in the lower movable portion 14.

The first upper fixing hole 331 of the first upper extending portion 33 communicates with the first lower fixing hole 132, and passes through the first upper fixing hole 331 with a fixing member 9 and is locked in the In the first lower fixing hole 132, the upper fixing portion 32 and the lower fixing portion 12 are fixed to each other to form a fixing portion. The second upper fixing hole 351 of the second upper extending portion 35 is sleeved in the second lower boss 151 and locked to the second lower fixing hole 152 by a fixing member 9 , the fixing member 9 There is a bolt head 91 which is larger than the second upper fixing hole 351, so that when the upper movable portion 34 and the lower movable portion 14 are combined into a movable portion, the upper movable portion 34 can be moved downward. The portion 14 moves up and down, but the upper movable portion 34 cannot be separated from the lower movable portion 14 by the engagement of the fixing member 9.

Since the soft material sensor 21 is used in the present button assembly 100, the soft material sensor 21 makes the sensing sensitivity of the pressure sensor 2 softer than a Flexible Printed Circuit (FPC) and pressure. The component sensor is large. When the user presses the pressure sensor 2, it is easy to cause an excessive change in the pressure value.
