Description of the Invention: [Technical Field] [0001] The present invention relates to a key device 'in particular to a toggle type button device ◊ [Prior Art] [0002] With the increase in the functionality of electronic devices, electronic devices The number of buttons that need to be set increases. In addition, various types of portable electronic devices are increasingly being developed in the direction of miniaturization. Therefore, it is necessary to minimize the area occupied by the keys. However, reducing the button area makes it easy for the user to press a few buttons at the same time or press the wrong button to cause an erroneous operation, which brings great inconvenience to the user. [0003] In order to solve the above problems, the industry has resorted to a toggle button that performs two or more operation commands by a single button. In use, different operation commands are completed by dialing the buttons in different directions. The toggle buttons commonly used in the industry generally include a key cover, an inner seat, a key body rotatably fixed between the key cover and the inner seat, and two springs fixed to the key body. The key body has a first contact column and a second contact column for touching piezoelectric electric shock. When assembling: firstly, the key body is fixed on the key cover and can be rotated relative to the key cover when the key body is toggled; secondly, the inner seat is fixed on the key cover, so that the key body is rotatably fixed to the inner seat and Between the key covers, the first contact column and the second contact column pass through the inner seat; finally, the two springs are respectively sleeved on the first contact column and the second contact column; when used: the key body is toggled, The key body is shifted to one side, and the first touch portion or the second touch portion touches the piezoelectric contact, and at the same time, the spring is compressed to accumulate an elastic force. After the stop is stopped, the spring releases the elastic force of the storage, and the key body is reset by the elastic force. 096133445 Form Compilation A0101 Page 5 of 17 0993273075-0 1332221 __ July 29, 2017, the shuttle replacement page [0004] However, the toggle button includes the key cover, the inner seat and the key body, It also includes two springs, so that the number of parts is large, and assembly is inconvenient. [0005] In view of the above, it is necessary to provide a button device with a small number of parts and convenient assembly. [0006] A button device includes a key body, a key cover and an inner seat, and the key body is located between the inner seat and the key cover. The key body comprises a body, two contact portions disposed on the body for contacting the piezoelectric contacts, and an operation portion for facilitating the movement.

The rebound portion is located between the two contact portions. The rebound portion includes a first action portion and a second action portion respectively opposite to the edge of the two contact portions on the body, and the first action portion and the second action portion respectively press the two touch portions when the operation portion is toggled The two edges. [0007] The button device is configured to press the edge of the touch portion by the rebound portion on the inner seat to return the key body to the untouched state. Therefore, the button device reduces the number of parts and reduces the assembly process. .

The two short sides of the main body 31 are provided with a semicircular recess 315 on the surface opposite to the key cover 20. The recess 315 is located opposite to the position of the rotating shaft fixing seat 23, and forms a shaft receiving space with the rotating shaft fixing seat 23. The rebound portion 33 has a bent or f-curved shape and is located between the short sides of the main body 31 to divide the hollow portion 311 into two portions. The rebound portion 33 includes a first action portion 331 and a second action portion 333 which are curved in shape, and a connecting portion which is located between the first action portion 331 and the second action portion 333 and has a linear shape. In the present embodiment, the first action portion 331 has a U shape, and the second action portion 333 has an inverted U shape. In other embodiments, the first action portion 331 and the second action portion 333 may also be V and w shapes, respectively. Other shapes such as bending or bending. 3, FIG. 4 and FIG. 5, the assembly darkness is first: first, the operation portion 13 of the key body 1 is passed through the through hole 29 of the key cover 20, and the rotation shaft 19 is received in the rotation shaft fixing seat of the key cover 2〇. In the portion 23, the two stopper portions 25 are stopped at both ends of the rotary shaft 19 to prevent the key body 10 from sliding in the direction of the rotary shaft 19. Next, the inner seat 3〇 is placed between the four positioning blocks 28, and the positioning hole 313 is opposed to the screw fixing seat 27 on the key cover 2, and the inner seat 3〇 and the key cover are fixed by fixing members such as screws and bolts. 20 is fixed together so that the key body 1 is disposed between the key cover 2〇 and the inner seat 3〇. At this time, the first contact portion 15 and the second contact portion 17 pass through the hollow portion 311, and the rebound portion 33 is located between the first contact portion 15 and the second contact portion 17. The first acting portion 331 on the resilient portion 33 is opposed to the flange 115, and the second acting portion 333 is opposed to the flange 113. When in use, a force is applied to the key body 1 拨 to move the operation portion 丨3 to one side, and the key body 10 rotates about the axis where the long axis 〇〇 is located, so that the first touch portion 15 touches the piezoelectric contact (Fig. Not shown). At the same time, the flange 115 on the key body 1 会 will reach 096133445 Form No. A0101 Page 8 / Total 17 Page 0993273075-0 [0013] 1332221 July 29, 2008 Correction of the first role of the replacement page pressure rebound portion 33 The portion 331 is elastically deformed to accumulate a force. When the force applied to the key body 10 is revoked, the first acting portion 331 releases the elastic force of its accumulation, and the pressing flange 115 returns the key body 10 to the untrimmed state, preparing for the next operation. Similarly, when a force is applied to the key body 10 to move the operation portion 13 to the other side, the operation principle of the key device 100 is the same. [0014] The button device 100 is pressed against the edge of the first contact portion 15 and the second contact portion 17 by the rebound portion 33 on the inner seat 30, so that the key body 20 is returned to the untouched state. The button device 100 reduces the number of parts, thereby reducing the assembly process. In addition, since the distance between the action point of the first acting portion 331 or the second acting portion 333 on the flange 115 or 113 and the axis where the long axis 00 > is large, the force is equal to the force multiplied by the force arm. In the case where the work is equal, when the arm is long, the action can be completed with a small force, that is, when the user gently dials the operation portion 13, a key position can be generated for the key body 10 to be nightly The work, marry and improve the operator's feel.
