Description of the Invention: [Technical Field] The present invention relates to a key structure, and more particularly to a key structure for an electronic device. [Prior Art] [0002] A button structure is often provided on the panel of an electronic device for controlling a power switch or performing other function adjustments. With the rapid development of the electronic industry, the requirements for control accuracy of buttons in an electronic device are also increased. The higher it is. [_3] A key structure' is provided on a casing of an electronic device. The housing is provided with a valley hole. The button structure includes a key cap and a key switch housed in the receiving hole. The bottom of the key cap is provided with a bump. The button is opened and closed with a trigger portion and a fixed contact, and the trigger portion is an arched elastic piece. The bump abuts against the top of the trigger. Pressing the key cap in the button structure, the bump pushes the trigger portion and is connected to the fixed contact; the key cap is released, and the trigger portion abuts the bump to reset the key cap. [〇〇〇4] However, in the above-mentioned button structure, due to manufacturing tolerances or assembly errors, it is easy to cause a certain gap between the bump of the key cap and the top of the trigger portion in the untriggered state, thereby forming an empty space. The stroke causes the above buttons and structures to be inferior. SUMMARY OF THE INVENTION [0005] In view of the above circumstances, it is necessary to provide a button structure having a better hand feeling when pressed and an electronic device having the same. [0006] A button structure, comprising a support member, a button switch provided on the support member and having a trigger portion, a key cap disposed relative to the trigger portion, and a key cap can be turned 099131346 Form No. A0101 Page 4 / Total 15 pages 0992054928-0201214487, the rotating member and the elastic member rotating member fixedly connected with the rotating member and the supporting member are rotated at an angle with respect to the elastic member in the untriggered state of the button switch, so that the elastic member provides a linear torque to the rotating member. [0007] The electronic device includes a housing and a button structure disposed on the bribe. The X body has an opening and a hole. The button structure includes a supporting member fixedly coupled to the housing and is supported on the support member. a key switch having a triggering portion, a key cap partially opposite to the triggering U and being received in the receiving hole, a rotating member fixedly connected to the key cap and the supporting member, and a magazine movably connected to the rotating member and the supporting member, the triggering portion The key member is abutted against the keycap in an untriggered state, and the rotating member is elastically deformed. The elastic member of the button structure provides an elastic torque to the rotating member when the button switch is not triggered, so that the key cap is kept in close contact with the trigger portion of the button switch, thereby avoiding a gap between the key cap and the trigger portion of the button switch. It has a better hand feeling when the above button structure is pressed.

In the present embodiment, the elastic member 70 is integrally molded of an elastic material. The fixing portion 71 is fixed to the baffle member by screws. Referring to FIG. 2 and FIG. 3 simultaneously, when the button structure 1〇3 is assembled, the middle portion of the rotating member 60 is first inserted into the elastic latching portion 72 of the elastic member. The two ends 61 of the rotating member 60 are respectively inserted into the shaft holes 151 from the notches 152 of the two series portions 15' of the keycaps 10, so that the rotating member 60 is rotatable relative to the keycap 10. The pressing portion 11 of the key towel field 1 is housed in the accommodating hole 102 of the casing 101. The first fixing portion 21 of the fixing bracket 20 is fixed to the inner side of the casing, and the two ends of the body 31 of the supporting p piece/' are fixed to the second fixing portions 23 of the fixing bracket 20. The key switch 5A is fixed to one side of the support member 30, and the fixing portion 71 of the spring & 70 is fixed to the support member 30. The rotating member 60 is rotated by a certain angle with respect to the elastic member 70 in a state where the key switch 5 is not triggered, so that the elastic member 70 provides an elastic torque to the keycap 1 (), thereby causing the keycap limiting portion 13 and the key switch 50. The trigger portion 51 is in close contact. When the button structure (10) is used, the pressing portion 1 of the keycap 1 is pressed, and the key 俨 1 滑动 is slid toward the trigger portion 51 of the key switch 5G until the trigger cap 5 is activated. The elastic snap portion 72 of the elastic member 7 is completely restored to deformation or elasticity. 099131346 Form No. A0101 Page 7 of 15 °992〇54928~〇 201214487 :?'. When the pressing portion η of the keycap 10 is released, the triggering portion of the key switch 5〇 is automatically reset to lift the keycap 1G, so that the rotating member _ is rotated by the elastic member 70 to provide an elastic torque to the rotating shaft. Further, the stopper portion 3 of the key towel 10 is kept in close contact with the trigger portion 按键 of the push button switch (9). [0021] * It should be noted that when the button switch 5{) of the button structure 1 () 3 is not triggered, the elastic torque applied by the rotating member 6 〇 to the key cap 1Q is less than that triggered by the trigger portion 51 of the _off 5 〇 The pressing force required at the time is to prevent the key switch 50 from being accidentally touched, so that the key switch 50 can work normally. The itch member 7 of the button structure 103 is provided with an elastic torque on the rotating side in the untriggered state of the button switch 50, so that the key lap is kept in close contact with the trigger switch #51 of the button switch ,, thereby avoiding the keycap 1〇 A gap is formed between the triggering portions 51 of the push button switch 5, so that the button structure 103 has a better hand feeling. [0022] It can be understood that the fixing bracket 2G can also be omitted, and at this time, the supporting member is directly fixed to the casing 101. [0023] The present invention has indeed met the requirements of the invention patent, and the patent is filed according to law. However, the above description is only a preferred embodiment of the present invention, which is not intended to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by those skilled in the art in light of the spirit of the invention should be covered by the following claims.
