[Embodiment] Please refer to FIG. 1. FIG. 1 is a schematic diagram of an electronic device 10 according to a preferred embodiment of the present invention. The electronic device 10 includes a button structure 12, a panel 14, and a switch 16 disposed on a substrate 15. The substrate 15 can be a printed circuit board. The button structure 12 is used to trigger the switch 16, which includes a pressing portion 18 and a protruding portion 20 connected to one side of the pressing portion 18, with 201112293 and two limiting portions 22, one end of each limiting portion 22 The pressing portion 18 is elastically deformed, and a guiding groove 22 is formed on each of the limiting portions 22. The pressing portion 18 and the protruding portion 20 can be integrally formed, and the limiting portion 22 and the pressing portion 18 can be integrally formed. For integral molding, the limiting portion 22 may be connected to the pressing portion 18 by means of hot melt or adhesive bonding. A guiding hole 141 is defined in the panel 14 , and the switch 16 is disposed on one side of the guiding hole 141 . The protruding portion 20 can be used to trigger the user to press the pressing portion 18 to be synchronously driven through the guiding hole 141 to trigger. The switch 16 is activated, and the switch 16 is triggered to generate a corresponding control signal. The button structure 12 further includes two fixing portions 24, one end of each fixing portion 24 is disposed in the corresponding guiding groove 221 and the other end is connected to the panel 14, so that the button structure 12 is not retained when the pressing portion 18 is pressed. Move in the X axis. The button structure 12 further includes two supporting portions 25 which are respectively disposed on one side of the two fixing portions 24. When the pressing portion 18 is pressed, the supporting portion 25 is used to support the limiting portion 22 so that the limiting portion 22 does not slip onto the panel 14. In addition, the fixing portion 24 can include a hook structure 26 for engaging with the guiding groove 221 to allow the limiting portion 22 to slide relative to the fixing portion 24. Therefore, when the button structure 12 is pressed, the relative angle between the pressing portion 18 and the limiting portion 22 changes with the pressing stroke of the button structure 12. The fixing portion 24, the supporting portion 25, the hook structure 26, and the panel 14 may be integrally formed. Please refer to FIG. 1 to FIG. 3 . FIG. 2 is a schematic diagram showing a state in which the key structure 12 is not pressed according to the 201112293 according to a preferred embodiment of the present invention. FIG. 3 is a schematic view showing a state in which the button structure 12 of the present invention is pressed according to the present invention. . As shown in FIG. 2 , when the pressing portion 18 is not pressed, the end of the limiting portion 22 is connected to the pressing portion 18 and is disposed at the other end between the fixing portion 24 and the supporting core, whereby the pressing portion 18 is pressed. In the initial position, as shown in FIG. 3, when the pressing portion 18 is pressed and moved in the Z-axis direction, the limiting portion 22 is connected to the pressing portion 18 at the end, and is empty. A guiding groove 221 is formed in the middle of the limiting portion 22, and the guiding groove 221 can be lowered or reset at the z-axis according to the fort, and the fixing portion 24, the supporting portion 25, and the hook structure of the panel 14 are The γ axis slides. That is, the fixing portion 24, the supporting portion 25, and the hook structure % of the panel 14 can restrict the restricting portion 22 from sliding only on the γ axis. At the same time, the guide hole (4) of the panel 14 can restrict the projection 20 from being lowered or reset on the z-axis. Therefore, when the button structure 12 is pushed, it can be displaced only in the Y-axis and the z-axis to prevent the pressing portion 18 from being twisted or skewed in a certain direction when pressed. Therefore, the protrusion 2 2 connected to the side of the pressing portion 18 can be driven in accordance with a predetermined path to trigger the switch 10, and the switch 16 can be triggered to generate a corresponding control signal. Therefore, it can be seen from FIGS. 2 and 3 that during the pressing process, since the stopper portion 22 can slide only on the Y-axis with respect to the fixing portion 24, the support portion 25, and the hook structure 26, the pressing portion 18 does not X-axis offset. At the same time, the guide hole 141 on the panel 14 restricts the projection 20 from being lowered or reset only in the z-axis, so that the pressing portion 18 is not offset or skewed on the Y-axis. On the other hand, when the pressure pressing the pressing portion 18 is released, the limiting portion 22 can be used to provide an elastic restoring force to the pressing portion 18' to return the pressing portion 18 to an initial position when it is not pressed. The guiding groove 221 can also slide the guiding position portion 22 relative to the fixing portion 24 in 201112293, and the limiting limiting portion 22 can only translate in the γ axial direction and the z axial direction, and cannot be axially translated in the χ direction, thereby preventing pressing. The position of the portion 18 is offset to avoid twisting or skewing when the pressing portion 18 is reset. In addition, the limiting portion 22 is composed of an elastic material. When the pressing portion 18 is pressed and moved in the z-axis direction, the connection between the limiting portion 22 and the pressing portion 18 is elastically deformed. The position portion 22 is not connected to the pressing portion 18 • One end portion is rotatable relative to the pressing portion 18 in the Z-axis direction; the limiting portion 22 may be designed to be pivotally connected to the pressing portion 18 as long as the limiting portion 22 can be pressed relative to the pressing portion The mechanism design of the rotation of the portion 18 is within the scope of protection of the present invention. Furthermore, the present invention can be provided with a component composed of an elastic material at a pivotal connection between the limiting portion 22 and the pressing portion 18 or at a connection between the limiting portion 22 and the fixing portion 24, thereby providing an elastic restoring force to The pressing portion 18 is configured such that the pressing portion "returns to the initial position when not pressed. The manner of providing and restoring the force to the pressing portion 18 so that the pressing of the ♦ (four) 18 to the initial position when not pressed is not limited to the above, According to the design requirements, since the limiting portion 22 can be composed of an elastic material, the guiding bow 22 of the limiting portion 22 can be engaged with the hook (10) by the elastic restoring force. 24 sliding 'It is not only easy to operate, but also disassembled. The combination of the position portion 22 and the mosquito portion 24 is not limited to the number and setting position of the road disclosed in the embodiment. For example, a plurality of sets of limiting portions can be set and fixed. In the 201112293 portion 24, a plurality of pairs of cantilevers are formed to increase the stability of the sliding of the guide groove 221 with respect to the fixed portion 24 when the pressing portion 18 is pressed. The end depends on the practical application. Further, the limiting portion 22 is connected to the fixed portion. The manner of the portion 24 may not be limited to the above, for example The array limiting portion 22 can partially slidably guide the guiding groove 221 on the fixing portion 24, and the remaining limiting portion 22 can be lockedly connected to the fixing portion 24, depending on the actual application. Compared with the prior art, the button structure of the present invention is provided with a guiding groove on the limiting portion, so that the limiting portion can slide relative to the fixed portion and the branch portion when the pressing portion is pressed, which can avoid the prior art being unpredictable The positional deviation caused by the cantilever twisting or skewing deformation can effectively avoid the offset of the button in the pressing stroke and improve the convenience of the group, and greatly improve the operational stability and convenience of the button structure. The preferred embodiments of the present invention are intended to be within the scope of the present invention. The first embodiment is a preferred embodiment of the present invention. 2 is a schematic view showing a state in which a button structure is not pressed according to a preferred embodiment of the present invention.
