Description

Technical Field

[0001] This application relates to the field of electronic technologies, and particularly to a pressing component and an electronic device. Background Art

[0002] In daily life, various electronic devices used by users are generally provided with buttons for adjusting volume or controlling power switches, etc. When the user presses the button into the electronic device, the end of the button triggers the corresponding button switch to achieve the corresponding function. When the button is in an unpressed state, a part of the button protrudes from the side of the electronic device. When the electronic device falls, the button is likely to be deformed or damaged due to impact. Once the button is deformed or damaged, phenomena such as key jamming or inability to be pressed are likely to occur, which in turn easily affects the normal use of the button. Therefore, there is an urgent need for a button with a lower deformation rate or damage rate when encountering impact. Utility Model Content

These attached drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those skilled in the art.

[0034] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the attached drawings.

[0035] As Figure 1 shown, an embodiment of the present application provides a pressing component, and the pressing component includes a button 100 and a carrier 200. It should be noted that the carrier 200 in the embodiment of the present application may be, for example, a middle frame of an electronic device. Generally, a button 100 switch corresponding to the button 100 is also provided in the electronic device. The carrier 200 is provided with a mounting hole 210. The button 100 is located in the mounting hole 210 and can move relative to the carrier 200. In this way, when the user presses the button 100, the button 100 can move and trigger the corresponding button 100 switch in the carrier 200 to implement functions such as power supply and volume control.

[0036] The button 100 has a locally resonant phononic crystal structure. It should be noted that the locally resonant phononic crystal structure has the characteristic of a low-frequency bandgap. Within a certain frequency range, the propagation of elastic waves within the locally resonant phononic crystal structure will be prohibited. Since the button 100 has a locally resonant phononic crystal structure, when the frequency of the elastic waves propagating in the button 100 approaches the resonance frequency of the resonance unit within the locally resonant phononic crystal structure, the resonance unit will strongly couple with the elastic waves, preventing them from continuing to propagate forward, that is, the elastic waves will be absorbed. Then, when the button 100 is struck, the locally resonant phononic crystal structure can play a role in damping vibration, so that the button 100 is not easily deformed or damaged, and it is not easy to have problems such as key jamming. This can not only ensure the normal use of the button 100, but also extend the service life of the button 100.

[0037] The following will Figures 1 to 3 provide a more specific and detailed description of the structures and functions of the various components of the pressing assembly provided in the embodiments of the present application.

[0038] Combined with Figure 1 and Figure 2 As shown, in some embodiments, the button 100 includes a pressing member 110 and a limiting member 120. The pressing member 110 includes opposite first surface 111 and second surface 112. The first surface 111 is connected to the limiting member 120, and the second surface 112 is for pressing. The pressing member 110 is a locally resonant phononic crystal structure. With such a setting, when the button 100 falls, the elastic waves generated by the fall will be transmitted from the second surface 112 to the first surface 111. Since the pressing member 110 is a locally resonant phononic crystal structure, it can absorb the elastic waves, preventing the elastic waves from being transmitted to the first surface 111, thereby achieving the effect of damping vibration and making the button 100 less likely to be deformed or damaged due to the impact caused by the fall, ensuring the normal use of the button 100.

[0039] The limiting member 120 passes through the mounting hole 210 and abuts against the inner wall of the mounting hole 210 provided on the carrier 200, so that the limiting member 120 can play a limiting role and prevent the button 100 from detaching from the carrier.

[0040] As Figure 2As shown, in some embodiments, the pressing member 110 includes an elastic body 113, a metal particle layer 114, and a hollow layer 115. The metal particle layer 114 and the hollow layer 115 are respectively located within the elastic body 113, and the metal particle layer 114 and the hollow layer 115 are arranged side by side at a first preset interval in the pressing direction. It should be noted that when the key 100 generates elastic waves due to dropping, the elastic body 113, the metal particle layer 114, and the hollow layer 115 will generate dipole resonance to absorb the elastic waves, thereby achieving the effect of shock absorption. The elastic body 113 in the embodiments of the present application can be made of an elastic material such as silica gel or rubber, for example.

[0041] As Figure 2 shown, in some embodiments, the distance between the metal particle layer 114 and the second surface 112 is less than the distance between the hollow layer 115 and the second surface 112. That is to say, the metal particle layer 114 is closer to the outside than the hollow layer 115, so that the shock absorption effect can be better achieved.

[0042] As Figure 2 shown, in some embodiments, the metal particle layer 114 includes a plurality of metal particles 1141, and the plurality of metal particles 1141 are evenly distributed. The hollow layer 115 includes a plurality of hollow structures 1151, and the plurality of hollow structures 1151 are evenly distributed. The hollow structures 1151 and the metal particles 1141 correspond to each other one by one in the pressing direction. With such an arrangement, the shock absorption effect can be better.

[0043] As Figure 2 shown, in some embodiments, the metal particles 1141 are metal spheres, and the centers of the plurality of metal spheres are located on a first plane 130. The hollow structures 1151 are hollow spheres, and the centers of the plurality of hollow spheres are located on a second plane 140. Both the first plane 130 and the second plane 140 are respectively parallel to the second surface 112. That is to say, the centers of the plurality of metal spheres are coplanar, and the centers of the plurality of hollow spheres are also coplanar. It should be noted that the material of the metal spheres can be a metal such as aluminum, steel, or lead. In some embodiments, the sizes of the metal spheres and the hollow spheres are the same, that is, the diameters of the metal spheres and the hollow spheres are the same, so that the shock absorption effect can be improved. It should be noted that the shapes of the metal particles 1141 and the hollow structures 1151 can be adjusted according to requirements. For example, they can both be cube-shaped, cuboid-shaped, etc.

[0044] As Figure 3As shown, in some embodiments, the pressing member 110 includes a plurality of metal particle layers 114 and a plurality of hollow layers 115. The metal particle layers 114 and the hollow layers 115 are alternately arranged at a second preset interval in the pressing direction. It should be noted that by arranging a plurality of metal particle layers 114 and a plurality of hollow layers 115, elastic waves can be absorbed more fully, thereby achieving a better vibration damping effect.

[0045] As Figure 2 shown, in some embodiments, the button 100 further includes a metal support member 150. The two sides of the metal support member 150 are respectively connected to the elastic body 113 and the limiting member 120. It should be noted that the material of the metal support member 150 can be, for example, metals such as aluminum, steel or lead. By providing the metal support member 150, a certain supporting effect can be exerted on the pressing member 110. In addition, since the hollow layer 115 and the metal support member 150 can generate mass-spring resonance, the vibration damping effect can be further achieved, so that the button 100 is less likely to be deformed or damaged when impacted, and the service life of the button 100 is extended.

[0046] Combined Figure 2 shown, in some embodiments, the orthographic projection area of the metal support member 150 on the second surface 112 is equal to the area of the second surface 112. With such an arrangement, the metal support member 150 can provide a better supporting effect for the pressing member 110.

[0047] On the other hand, the embodiments of the present application also provide an electronic device, and the electronic device includes the pressing assembly described in any one of the above. It should be noted that the composition and functions of the pressing assembly in the electronic device are the same as those of the pressing assembly provided in the embodiments of the present application above, so the embodiments of the present application will not be elaborated here. Since the pressing assembly can prevent the button 100 from being deformed or damaged when encountering an impact, the button 100 is not likely to have problems such as key jamming, ensuring that the button 100 can be used normally, thereby extending the service life of the button 100 and also extending the service life of the electronic device.

[0048] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
