Description

Button structure

The invention relates to a button structure, in particular to a button structure for an electronic product.

A button structure is often provided on the panel of the electronic device for controlling the power switch or performing other function adjustments. With the rapid development of the electronics industry, the overall structure of electronic devices tends to be light, thin, and small, and the button structure in electronic devices is also required to be simplified.

A button structure includes a button cap and a button pad. The button cap and the button seat are engaged with each other. The button structure presses the button to press the electronic component communication circuit in the electronic device.

However, in the above button structure, the positioning between the button cap and the button seat is inaccurate, and the assembly is not easy, resulting in inconsistent touch feeling. In the manufacturing process of the electronic device, it is necessary to draw a symbol on the button cap by laser marking. The button structure is difficult to accurately assemble to the marking fixture because there is no positioning structure, which brings certain difficulties to the marking operation of the button cap. .

In view of the above circumstances, it is necessary to provide a button structure which is preferable in that the pressing feel is easy and the positioning is easy and the marking operation is easy.

A button structure, including a button cap, a button seat connected to the button cap, and In the bonding member of the bonding button cap and the button seat, the edge of the button cap is extended to form an outer edge, and the outer edge of the button cap is provided with a notch, and the notch depth on the outer edge of the button cap is smaller than the height of the outer edge of the button cap. The outer edge cooperates with the button seat to close the bonding member between the button cap and the button seat.

In the above button structure, the button cap and the button seat cooperate with each other and are connected by using an adhesive member to ensure accurate and firm assembly. And the button cap is stuck on the button seat to completely cover the bonding between the two to ensure the pressing feeling. In addition, when marking the button cap before assembly, the marking fixture can be matched with the outer edge of the button cap to accurately position the button cap for marking work.

FIG. 1 is a perspective view showing a key structure of an embodiment of the present invention.

Figure 2 is an exploded perspective view of the button structure shown in Figure 1.

The key structure of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 and FIG. 2 together, the button structure 9 in the preferred embodiment is a power button structure. The button structure 9 includes a button cap 10, a button pad 20, and an adhesive member 30 disposed between the button cap 10 and the button pad 20. In this embodiment, the bonding member 30 is a double-sided tape.

The button cap 10 includes a mounting surface 11 and an annular outer edge 12 extending perpendicularly from the edge of the mounting surface 11, such that the button cap 10 has a certain depth. The mounting surface 11 is a flat surface. The outer edge 12 is provided with a notch 121. In the embodiment, the depth of the notch 121 is smaller than the height of the outer edge 12, and the bottom of the notch 121 is at a certain distance from the mounting surface 11 of the button cap 10. The button seat 20 is substantially The cylindrical button body 20 includes a mating surface 21 and a plurality of arcuate positioning grooves 22 formed at the edges of the mating surface 21. The mating surface 21 is a flat surface. An engaging portion 23 that engages with the notch 121 of the button cap 10 is formed between the two adjacent positioning grooves 22. In the embodiment, the button cap 10 is provided with three notches 121. Correspondingly, the button pad 20 is provided with three engaging portions 23. The engaging portion 23 is flush with the mating surface 21 of the button base 20 to ensure that the bonding member 30 disposed between the button cap 10 and the button housing 20 is relatively flat.

The button cap 10 is shaped to fit the button holder 20. The outer edge 12 of the button cap 10 is embedded in the positioning groove 22 of the button holder 20, and the engaging portion 23 on the positioning groove 22 is engaged with the notch 121 on the outer edge 12. The bonding member 30 is disposed in the outer edge 12 of the button cap 10 and located between the button cap 10 and the button holder 20, and is connected to the mating surface 21 of the mounting surface 11 of the button cap 10 and the button holder 20. Since the notch on the outer edge 12 of the button cap 10 has a certain distance from the mounting surface 11 of the button cap 10, the distance is greater than the thickness of the bonding member 30, so that the button cap 10 and the button holder 20 completely close the bonding member 30.

With such a button structure, the button cap 10 and the button pad 20 are engaged with each other, and the fit is not easy to be offset. The bonding member 30 is received in the gap between the mounting surface 11 and the mating surface 21, and the bonding member 30 is completely enclosed between the button cap and the button holder, and the bonding member 30 is not easy to overflow during assembly, and the bonding member 30 It is relatively flat and does not cause inconsistent press feeling. The process of removing the overflow glue can be eliminated. In addition, when the button 9 of the structure is used for marking the button cap 10, the outer edge 12 of the button cap 10 and the notch 121 on the button cap 10 can be used for positioning to accurately mark the button.

It can be understood that in the button structure of the present invention, the shape, position and number of the notch 121 on the button cap 10 and the engaging portion 23 on the button pad 20 corresponding thereto can be freely set or omitted according to actual conditions. The shape and position of the outer edge 12 of the button cap 10 and the positioning groove 22 on the corresponding button seat 20 can be freely set according to actual conditions. The structure of the button base 20 It is not limited to a cylindrical shape, and may be a cylindrical shape having a square shape or other shapes. Correspondingly, the button cap 10 can also have other shapes. The mating surface 21 of the mounting surface 11 of the button cap 10 and the button holder 20 may be other shapes that are easy to assemble and ensure a good touch feeling. And the bonding member 30 may be another adhesive for bonding the button cap 10 to the button pad 20.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by the person skilled in the art of the present invention should be included in the following claims.
