Field of the Invention The present invention relates to a key structure, and more particularly to a key structure that can prevent false touches and also has a waterproof function. Prior Art Referring first to Figure 1, this figure shows the schematic of a known button structure. The button structure as shown in FIG. 1 is usually disposed inside an electronic device housing 10 and can be used as one of the reset devices. As shown in the figure, the conventional button structure mainly includes a movable member 20, a substrate 3A, and a switching element 4, wherein the switching element 40 is disposed on the substrate 30, and is permeable when the switching element 40 is triggered. The circuitry on substrate 30 transmits an electronic signal to a processor. The movable member 20 has a pressing portion 2 0 1 located at the opening 1 〇 of the housing 1 ,. When the switching element 40 is to be triggered, a downward external force can be applied to the pressing portion 2 〇1, and the movable portion is movable at this time. The member 20 will move downward and trigger the switching element 40. In order to facilitate the user's pressing, in general, the movable member 2 is adjacent to the switching element 40'. However, when the surface 1 〇1 of the housing 1 is subjected to a downward external force (as shown in FIG. 1), it may The movable member 2 is pressed to the lower switching element 40 to cause an accidental touch. In addition, moisture or liquid may also penetrate into the electronic device through the gap between the casing 丄〇 and the movable member 20. In view of this, how to provide a key structure that can prevent false touches and has a waterproof function has become an important issue. SUMMARY OF THE INVENTION In order to improve the disadvantages of conventional buttons, the present invention provides a button structure that is suitable for use in an electronic device, wherein the electronic device has a housing.

DESCRIPTION OF THE INVENTION (2) The key structure of the present invention mainly comprises a substrate, a movable member, a buffering member and a switching element. The movable member is movably coupled to the housing and movable between a first position and a second position relative to the housing. The buffering element is disposed on the substrate and is located between the substrate and the movable member. The switching element is disposed on the substrate. When the movable member is in the first position, the buffering member abuts the movable member and causes the switching element to be spaced apart from the movable member. In addition, when the movable member moves from the first position toward the substrate to the second position, the movable member triggers the switching element, and at this time, the cushioning member is pressed by the movable member to apply a restoring force to the movable member, thereby returning the movable member to the first position. position. In the embodiment of the present invention, the housing has an opening, and the movable member is a drinking portion, and the pressing portion is located in the direction of the opening and moves toward the substrate. Ugly, in the embodiment of the vehicle, the movable portion is straighter than the moving direction of the movable member, wherein the member f has a flange, approximately a vertical edge, for supporting the movable member. In the preferred embodiment, the member protrudes from the housing, and the movable member is disposed between the first and second positions. In the preferred embodiment, in the foregoing preferred embodiment, the foregoing switch:: two: cotton material. In a preferred embodiment, the spacing 2 is a touch switch. For the above and other purposes of the present invention, 'two questions. It is to be understood that the specific features and advantages of the present invention will be more apparent.歹也歹, and with the drawings to make detailed 0798-A20961TWF (N2); C050l3; 1ILlN> ptd 200641652 V, the invention description (3 One of the reset buttons, the main spoon is placed on the substrate 30, a switching element 40, and a buffer element =: the moving member 20, the member 40 is disposed on the substrate 30, when the switching element 4 〇 is triggered = the circuit on board 30 transmits an electronic signal to the processor. Specifically, the snubber can be provided by the snubber element 5 disposed on the substrate 30. Above the support; move: 20, such that when the surface of the housing of the electronic device 1 is pressed and pressed (as indicated by the direction of the arrow in FIG. 2), the lower door_element 40 is not triggered. This prevents accidental touches. In a preferred embodiment, the buffering member 50 can be made of foam material, and the switching element 4 can be a tactile switch. Referring to Figure 23, the two figures show a schematic view of the movable member 2 〇 in a first position and a second position, respectively. In this embodiment, the movable member 20 is slidable in a guide groove portion 1〇2, and the guide groove portion ι2 protrudes from the inner side of the housing 10, and the moving direction of the movable member 2〇 is substantially Straight to the housing 10. As shown in FIG. 2, when the movable member 2 is located at the first position %, the buffering member 50 is located between the movable member 2A and the substrate 3A, wherein the cushioning member 50 abuts against the movable member 2 The outer flange 2 is 2, and the switching element 40 is separated from the movable member 2 by a distance D. In this way, when the outer surface of the casing 101 is forced to the external force, the movable member 2 is supported by the cushioning member 5, which does not trigger the lower switching member 40. In a preferred embodiment, the flange 2 0 2 is approximately perpendicular to the direction of movement of the movable member 2, and the distance D between the switching element 40 and the movable member 2 is approximately 1 min.

Inventive Description (4) In Figures 2 and 3, the movable member 20 has a pressing portion 201 above, wherein the pressing portion 2 0 1 is movable The ground is located in one of the openings 10' of the housing 10. As shown in Fig. 3, when the pressing portion 201 is subjected to a downward external force, the movable member 2 is moved from the first position toward the substrate 30 to the second position, thereby triggering the switching element 40. In particular, at this time, the cushioning member 50 is deformed by being pressed by the movable member 20, so that a restoring force can be generated to the movable member 2〇, whereby the movable member 20 can be returned to the first position after the external force is released. . In the embodiment, the movable member 2 has a first bending portion Μ and a second bending portion b2, wherein the first and second bending portions M and b2 are adjacent to the groove portion 102. In this way, the contact area between the movable member 2〇 and the guide groove portion 1〇2 can be increased, thereby reducing the penetration of moisture or liquid. In summary, the present invention provides a button-sister, once you, the Du Fu Shi g-mouth structure, by placing a punching member on the substrate to support the movable member, and at the same time making a gap, thereby being able to move The spacing between the piece and the 70 piece of the switch effectively prevents the housing from being dismantled by the outer six. touch. Since the mechanism of the present invention is simple, and the error generated by t, can be widely applied to various electronic devices. The advantages of his cost, therefore, although the present invention has been disclosed in the context of the invention, such as μ, the invention is limited, and anyone skilled in the art can use it to make a little more And without departing from the scope of the invention, the scope of the invention is as defined by the patent specification of the patent.
