As shown in FIG. 2, the button device of the embodiment of the present invention includes a pressing assembly 10, a button holder 20 and an elastic returning member 30. The pressing assembly 10 includes a relatively fixed button cap 11 and a slider 12, and the button holder 20 includes a protruding edge. The body 21 and the body 21 are provided with a protrusion 22 of the track groove 23, and the elastic returning member 30 is sleeved on the outer surface of the protrusion 22 and elastically abuts against the button cap 11 and the body 21 respectively. Referring to FIG. 6, the track groove 23 is at least The first locking position 01 and the second locking position 02 are included, and during the pressing of the button cap 11, the sliding member 12 slides in the track groove 23 and locks in the first locking position 01 and the second locking position 02. .

In this embodiment, as shown in FIG. 3, the height of the pressing assembly 10 is smaller than the button seat 20. The elastic recovery member 30 is a compression spring. In other embodiments, the elastic recovery member 30 may also be an elastic material such as silica gel. Here, for the convenience of pressing, the outer surfaces of the button cap 11 and the button holder 20 are both annular.

The pressing assembly 10 is of a detachable structure, and the slider 12 is fixed to the button cap 11. The sliding member 12 includes a fixing portion 12a, a connecting portion 12b extending perpendicularly to the fixing portion 12a, and a bent portion 12c which is bent twice from the connecting portion 12b and parallel to the fixing portion 12a. The fixing portion 12a is fixed at the button On the cap 11, the bent portion 12c slides in the track groove 23.

Specifically, the fixing portion 12a is annular, and the inner surface of the top of the button cap 11 is provided with a stud 11a, and the fixing portion 12a is engaged with the outer surface of the stud 11a.

The inner surface of the top of the button cap 11 is further provided with a first annular groove 11b. One end of the elastic returning member 30 is embedded in the first annular groove 11b. The inner surface of the bottom of the button base 20 is provided with a second annular groove 20a. The other end of 30 is embedded in the second annular groove 20a.

6 and 7, the track groove 23 is formed as a closed groove body, and the protrusion 22 is divided into a limit frame 22a outside the track groove 23 and a limit table 22b inside the track groove 23, the first locking position. 01 relative The second locking position 02 is disposed at a lower portion of the track groove 23.

The track groove 23 includes a first track portion 231 on the left side and a second track portion 232 on the right side, and the first lock position 01 and the second lock position 02 are respectively located at both ends of the first track portion 231, the first track One end of the portion 231 near the second locking position 02 is lower than the end of the second rail portion 232 near the second locking position 02, and the end of the first rail portion 231 near the first locking position 01 is higher than the second rail portion 232. One end of the first locking position 01.

In order to facilitate the reliable positioning of the bending portion 12c at the first locking position 01, the lower end of the limiting table 22b is recessed, and the bending portion 12c is less likely to be displaced after moving to the position.

In this embodiment, the bottom surface of the second rail portion 232 includes a second surface S _b , a third surface S _c , and a fourth surface S _d which are sequentially connected from bottom to top; the bottom surface of the first rail portion 231 includes the top surface The fifth surface S _e , the sixth surface S _f , the seventh surface S _g , the eighth surface S _{h ,} and the first surface S _a , the eighth surface S _h , the first surface S _{a ,} and the second surface S _b composition inverted shape of "V", i.e., in the sliding direction of the button cover 11, the first surface is higher than the eighth surface S _a S _h and S _b of the second surface of the lowest position. Wherein the second locking position 02 located at the top of the fifth surface S _e, a first locking position 01 on the first surface S _a.

Further, in order to ensure the irreversibility of the direction in which the bent portion 12c slides in the track groove 23, the fourth surface S _d and the fifth surface S _e , the seventh surface S _g , the eighth surface S _h , and the eighth surface _SH The transition surface of the first surface S _a , the first surface S _a and the second surface S _b is a step transition, and at the transition surface, the fourth surface S _{d is} higher than the fifth surface S _e , and the seventh surface S _{g is} high In the eighth surface S _h , the eighth surface S _{h is} higher than the first surface S _a , and the first surface S _{a is} higher than the second surface S _b , so that the bending portion 12 _c can only rotate in the counterclockwise direction shown in FIG. 6 . In order to ensure the continuity of the sliding portion 12c sliding in the track groove 23, a bevel or arc transition is adopted between the transition faces of the fifth surface S _e and the sixth surface S _f , and the second surface S _b and the third surface S _c . The fourth surface S _d adopts a slope or a curved surface transition between every two adjacent faces.

3 to 5, in the natural state, the top end of the button cap 11 is flush with the upper surface of the button holder 20, and the overall appearance effect is good. At this time, the bent portion 12c is locked in the first locking position 01; During the pressing operation, when it is necessary to change the position of the button cap 11 to achieve some specific functions, the button cap 11 is pressed, and the bent portion 12c slides along the second surface S _{b of} the second rail portion 232 until the button cap 11 is recessed. The upper surface of the button base 20 reaches the extreme position of the lower end, and then the external force is removed, and the bending portion 12c is automatically slid under the action of the compression spring to the second locking position 02, and the button cap 11 protrudes from the upper surface of the button seat 20; when a change of position of the key cap 11 again, the cap 11 is pushed again, the bent portion 12c slides along the first rail portion 231 to the eighth surface S _a, i.e., to the first locking position where the first surface 01 S _a In this cycle, the state of the button device can be constantly changed.

In addition to being a button, as an embodiment of the present invention, the button device can also be applied to a tablet In electronic devices such as computers, mobile phones, and cameras, it acts as a protection port for plug-in ports such as data interfaces, headphone jacks, and charging ports. Specifically, one side of the button cap 11 is provided with an interface (not shown) connected with a corresponding function circuit. When the button cap 11 is pressed and popped up, the height of the interface is higher than the button seat 20 for external connection (Fig. When the button cap 11 is pressed again, the interface is accommodated in the button holder 20 as the button cap 11 sinks, which can effectively prevent dust, moisture, etc. from entering, and the operation is simple and practical. It can be understood that the interface is not limited to a data interface, a headphone jack, a charging port, and the like.

The button device of the invention has fewer structural components, high reliability and longer service life; at the same time, after the pressing assembly is in the depressed state, the top end is not higher than the upper surface of the button device, and the knob for operation in the prior art is avoided. The phenomenon that always protrudes from the outside of the body optimizes the overall appearance of the device.

The above description is only a specific embodiment of the present application, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present application. It should be considered as the scope of protection of this application.
