[Embodiment] The following will be combined with the specific embodiment. The key structure of the present invention and the electronic device having the same are described in detail. "Monthly, referring to FIG. 1 and FIG. 2', the electronic device 1 includes various functional modules for implementing various functions L for saving space. The present embodiment is the same as that of the housing 101 of the electronic device 100 and the button structure 103 fixed to the housing 101. Specifically, in the present embodiment, the button structure 103 is a function table button of the electronic device 100, and the casing 101 is an outer casing of the electronic device. A receiving hole 102 is defined in the housing 101. [0011] The button structure 103 includes a keycap 10, a fixing bracket 20, a support member 30, a push button switch 50, and an elastic member 60 and a fixing member 70. The button cap 10 is partially received in the receiving hole 102 of the housing 101. The fixing bracket 20 is fixed to the inner side surface of the casing 101 and disposed adjacent to the receiving hole 102. The support member 30 is fixedly coupled to the fixing bracket 20 and disposed opposite to the receiving hole 1〇2. The push button switch 50 is fixed to the support member 30. The elastic member 60 is rotatably coupled to the keycap 10 and the fixing member 70. The fixing member is fixedly connected to the support member 30. [0012] The keycap 10 includes a pressing portion 11, a limiting portion 13, and two connecting portions 15. The press portion 11 is substantially elliptical in shape and is slidable in the receiving hole 102 of the housing 101. The stopper portion 13 is provided on one side of the pressing portion 11. The size of the limiting portion 13 is larger than the size of the receiving hole 102 of the housing 101 to prevent the pressing portion 11 from coming off the receiving hole 102. The two connecting portions 15 are respectively provided at both ends of the outer surface of the limiting portion 13. In the present embodiment, each of the connecting portions 15 is provided with a shaft hole 151 and a notch 152 communicating with the shaft hole 151. [0013] The fixing bracket 20 includes a first fixing portion 21, two second fixing portions 23 and a third fixing portion 25. The first fixing portion 21 is a rectangular plate body that is fixed to the inner side of the casing 101. The second fixing portions 23 are bent and extended from both ends of the first fixing portion 21 side. Both ends of the third fixing portion 25 are connected to the second fixing portions 23, respectively. The first fixing portion 21, the second fixing portion 23, and the third fixing portion 25 together form an annular frame. In the present embodiment, the first fixing portion 21 is fixed to the inner side of the casing 101 by welding. Third Solid 099131348 Form No. A0101 Page 6 of 17 0992054930-0 201214484 The fixed portion 25 is for fixing other components (not shown) of the electronic device 100. [0014] The support member 30 includes a body 31 and a support portion 32 disposed at a middle portion of the body 31. A through hole 312 is defined in each of the two ends of the body 31. The body 31 is fixed to the second fixing portion 23 of the fixing bracket 20 by a through hole 312 through a screw (not shown). [0015] The push button switch 50 is fixed to the support portion 32 of the support member 30 (see FIG. 4). The push button switch 50 has a trigger portion 51. The stopper portion 13 of the keycap 10 presses the trigger portion 51 to activate the key switch 50. In the present embodiment, the push button switch 50 is fixed to the support member 30 by welding. [0016] The elastic member 60 includes a rotating portion 61 and an elastic supporting portion 62 connected to the rotating portion. Both the rotating portion 61 and the elastic supporting portion 62 are substantially U-shaped, and both ends of the rotating portion 61 are respectively connected to both ends of the elastic supporting portion 62, and finally form a substantially "concave" type structure. The size of the rotating portion 61 is larger than the size of the elastic supporting portion 62, and the two are not coplanar, i.e., the elastic supporting portion 62 is inclined with respect to the rotating portion 61. In the present embodiment, the elastic member 60 is made of elastic steel wire. [0017] The fixing member 70 includes a fixing portion 71, two first hooks 72 and a second hook 73 provided on the fixing portion 71. In the present embodiment, the fixing member 70 is integrally molded of an elastic material. Referring to FIG. 2 to FIG. 4 simultaneously, when the button structure 103 is assembled, the middle portion of the rotating portion 61 of the elastic member 60 is firstly engaged in the second hook 73 of the fixing member 70, and the two sides of the rotating portion 61 are respectively It is snapped into the first hook 72 of the fixing member 70. The two ends of the elastic member 60 are respectively inserted into the shaft holes 151 from the notches 152 of the two connecting portions 15 of the keycap 10, so that the elastic member 60 is rotatable relative to the keycap 10. 099131348 Form No. A0101 Page 7 of 17 0992054930-0 201214484 The pressing portion 11 of the keycap 10 houses the holder 2. The first-fixed knowledge: the body 101 is accommodated in the hole 102. The solid 30 of the fastener 30 is fixed to the inner side of the casing 101. The support and the fixed bracket 20 are second __ =. The elastic member 6 is in a state where the button 71 is opened and the fixing portion 71 of the α stator 70 is solidly activated. : 3 pieces on the board. The non-rotating portion of the push button switch 50 corresponds to the fixing member 7 〇 rotated - the fixed angle 'the fourth cutting portion 62 is elastically deformed by the pressing against the supporting member 3G, and the elastic restoring force is provided to the rotating portion 61 of the elastic member (10). On the other hand, the stopper portion 13 of the key t mesh 10 is in close contact with the trigger portion η of the push switch 5A. When the button structure 103 is used, the pressing portion η of the key pad is pressed, and the key cap _ is slid toward the trigger portion 51 of the button _5 , until the button switch 50 is triggered. The elastic branch portion 62 of the elastic member 60 is completely restored to deformation or the elastic variable is reduced. When the pressing portion 11 of the keycap 10 is released, the triggering portion 51 of the key switch 50 is automatically reset to lift the keycap 1Q, so that the elastic fine rotation (10) corresponds to the rotation of the fixing member 7G - in degree "to make the elastic member 6 () The elastic support portion 62 is deformed, and the elastic portion 61 of the key iflG is kept in close contact with the trigger portion 51 of the key switch 5 (). [_ f To explain: the button switch 1{) 3 button switch 5 () is not touched, the elastic torque applied by the elastic member 60 to the key cap 10 is smaller than the pressing force required for the trigger switch of the button switch 5 () Therefore, the key switch 5〇 is prevented from being accidentally touched, so that the key switch 50 can work normally. [〇〇21] The elastic supporting portion 62 of the elastic member 60 of the above-mentioned button structure 丨〇3 is in a state of being untriggered by the key switch 50, and is abutted against the supporting member 7Q of the fixing member 7Q. 0992054930-0 099131348 Form No. A0101 Page 8 of 17 201214484 [0022] 〇 [0023] [0028] [0028] [0028] Elastic deformation, providing an elastic back to keep the keycap 1G and the button open 9 elastic member 6Q The rotating portion 61 prevents the key (4) from coming into close contact with the trigger portion 51 of the push switch 5, thereby eliminating a gap between the trigger portions 51 of the idle stroke during pressing, and a better hand feeling. According to the button structure 103, it can be understood that the fixing bracket 20 can be saved on the housing ιοί "fixing member 7" / at this time, the supporting member 30 directly fixes the moving portion 61 and the supporting member 3G to omit 'only The connecting member of the elastic member 60 is required to have a connecting portion having a shaft hole, for example, a shaft hole of the supporting member. The rotating portion 61 of the member 60 is provided. The present invention has indeed met the requirements of the invention patent, and is requested in accordance with the law. However, the above is only the preferred embodiment of the present invention: it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
