The material of the key 200 may be rigid plastic, rubber or metal, and in a more preferable embodiment, the material of the key 200 may be aluminum. Specifically, the key 200 includes a key body 210 and an elastic clip 220, the key body 210 includes a mounting portion 211, and at least a part of the mounting portion 211 is clipped in the mounting space 110 through the elastic clip 220, so that the key 200 can be hung on the device housing 100.

In the embodiment of the present invention, at least a portion of the mounting portion 211 passes through the first mounting hole 120 and is located in the mounting space 110, the elastic clip 220 is disposed at a position of the mounting portion 211 located in the mounting space 110, and the elastic clip 220 and the mounting portion 211 are disposed in various manners, such that the elastic clip 220 can be adhered to the mounting portion 211, or the elastic clip 220 can be disposed on the mounting portion 211 in a snap-fit connection manner.

The mounting space 110 is provided with a hanging part 111, and the elastic latch 220 elastically abuts against the hanging part 111, so as to realize hanging fit with the hanging part 111.

According to the electronic equipment disclosed by the embodiment of the invention, the hanging area on the key 200 is improved into the mounting part 211 and the elastic clamping piece 220, then the elastic clamping piece 220 is clamped with the mounting space 110 on the equipment shell 100, so that the key 200 can be stably hung on the equipment shell 100 of the electronic equipment, specifically, at least part of the mounting part 211 passes through the first mounting hole 120 and is positioned in the mounting space 110, the elastic clamping piece 220 is arranged on the part of the mounting part 211 positioned in the mounting space 110, the elastic clamping piece 220 elastically abuts against the hanging part 111, so that the elastic clamping piece 220 can be stably clamped in the mounting space 110, the key 200 can be firmly hung with the equipment shell 100, the key 200 can be stably installed and is not easy to fall off after being installed, and the reliability of the electronic equipment can be finally improved; further, the key 200 has a simple structure, so that the processing technology is simple and the mass production is high.

It can be seen that, compared with the electronic device described in the background art, the key 200 of the electronic device disclosed in the embodiment of the present invention is not easy to fall off, so that the electronic device has higher reliability.

In the embodiment of the present invention, the elastic clip 220 may be of various types, such as a V-shaped strip or a rubber block, and in a preferred embodiment, the elastic clip 220 may be a torsion spring, an end of the torsion spring may abut against the hanging portion 111, and the torsion spring has a simple structure, so that the torsion spring is easy to mass produce, and the production cost is low. Meanwhile, the torsion spring has higher stability and is difficult to lose efficacy, so that the key 200 can be hooked more reliably.

Generally, the contact area between the two ends of the torsion spring and the hanging part 111 is small, which results in low stability of the key 200 hanging on the device housing 100 and may result in a risk of dropping the key 200, and therefore, in order to further improve the hanging stability of the key 200 and the device housing 100, the risk of dropping the key 200 is greatly reduced. In a preferred scheme, the torsion spring may include an end bending portion, the end bending portion elastically abuts against the hanging portion 111, the end bending portion can increase the contact area between the torsion spring and the hanging portion 111, so that the elastic latch 220 can elastically abut against the hanging portion 111 more stably, thereby preventing the elastic latch 220 from abutting against the equipment housing 100 difficultly due to the fact that the key main body 210 is difficult to abut against the equipment housing 100 due to the smaller abutting area or the poorer abutting effect of the elastic latch 111, and further improving the hooking stability and reliability of the key 200.

As described above, the elastic clip 220 and the mounting portion 211 can be disposed in various ways, and the elastic clip 220 can be adhered to the mounting portion 211 or can be disposed on the mounting portion 211 by being snapped. In a preferred scheme, the key main body 210 further includes a key cap 212, the mounting portion 211 is connected to the key cap 212, the mounting portion 211 can include a mounting base 2111 and a mounting post 2112 disposed on the mounting base 2111, and the torsion spring can be sleeved on the mounting post 2112, so that the torsion spring and the mounting portion 211 can be mounted simply and easily, and the connection is reliable, thereby enabling the elastic clamping piece 220 to be mounted and matched with the mounting portion 211 more conveniently, reducing the probability of error in the mounting process, and further improving the assembling performance and reliability of the electronic device.

In a more preferable scheme, the installation base 2111 may be a sunken platform, specifically, in a direction perpendicular to the installation base 2111, the size of the installation base 2111 may be smaller than that of the installation portion 211, and this scheme may make the installation base 2111 have a smaller thickness, thereby facilitating saving of the installation space 110, further reducing the difficulty of structural design of a connection portion between the key 200 and the device housing 100, facilitating production of the device housing 100, and facilitating reduction of cost.

As described above, the hanging portion 111 is disposed in the installation space 110, in a preferred embodiment, the hanging portion 111 may be a hanging surface, the device housing 100 includes the edge portion 112 enclosing the first installation hole 120, the inner side surface of the edge portion 112 may be a hanging surface, the hanging surface is in abutting fit with the elastic clip 220, specifically, the edge portion 112 and the installation space 110 may form a hanging step, the hanging step may form a hanging surface, and the hanging surface may provide a reliable fulcrum for the elastic clip 220, so that the elastic clip 220 can be better supported to be clipped in the installation space 110, and further, the reliability of the key 200 and the device housing 100 in hanging is higher.

In the embodiment of the present invention, when the key 200 is installed, the key cap 212 needs to be pressed on the front surface, so that the elastic latch 220 can be compressed and inserted into the installation space 110 under the guiding action of the first installation hole 120, and after the elastic latch 220 is forced to be pressed into the installation space 110, the elastic latch 220 can elastically recover to the natural state, so that the two ends of the elastic latch 220 can be clamped in the installation space 110, but when the key 200 needs to be disassembled, because the two expanded ends of the elastic latch 220 abut against the hanging part 111, the disassembly is difficult. Therefore, in a preferred scheme, the edge portion 112 can be a thermoplastic plastic portion, and when the key 200 needs to be detached, only the edge portion 112 needs to be heated, so that the edge portion 112 can be deformed or softened, the elastic clip 220 can be conveniently pulled out smoothly along with the key 200, the key 200 can be conveniently detached, and the detachment efficiency can be greatly improved. In a more preferable scheme, the edge 112 may be a memory metal part, and after the elastic clip 220 is pulled out, the temperature of the edge 112 is restored to normal temperature, so that the edge 112 can be restored to an initial shape, thereby facilitating the repeated use of the device housing 100, reducing the maintenance cost, and finally improving the maintainability of the electronic device.

In general, after the electronic device is installed, the edge portion 112 may be surrounded by other components or covered on the outside thereof, so that when the key 200 needs to be detached, the edge portion 112 is inconveniently heated or the heating effect on the edge portion 112 is poor, thereby affecting the detaching operation of the key 200. Based on this, in a preferred scheme, the key main body 210 may further include a heat conduction portion, the heat conduction portion is disposed in the key main body 210, the heat conduction portion extends from the outer side surface of the key main body 210 to the direction of the installation portion 211, the installation portion 211 is in heat conduction contact with the edge portion 112, the heat conduction coefficient of the heat conduction portion may be greater than that of the key main body 210, when the edge portion 112 needs to be heated, only the heat conduction portion on the key main body 210 needs to be heated, the heat conduction portion can well transfer heat to the edge portion 112, the edge portion 112 can be heated conveniently, effectively and quickly, and further the disassembly efficiency of the key 200 can be greatly improved. In particular, the heat conducting portion may be made of a material having a higher thermal conductivity, such as copper or aluminum.

In a more preferable embodiment, the key main body 210 may have a filling space, and the heat conducting portion may be disposed in the filling space, and specifically, the heat conducting portion may be a heat-melting portion. Specifically, the hot-melting part may be a hot-melting metal or a hot-melting polymer material. In the embodiment of the present invention, the heat-fusible part refers to a part that can be melted when heated to a preset temperature.

As described above, the key body 210 may have a filling space, and generally, the filling space may be disposed in various ways, which is not limited in the embodiment of the present invention. In a preferred embodiment, the filling space may be a closed inner cavity, specifically, the closed inner cavity may be directly formed during the processing of the key body 210, and the hot-melt portion is filled in the closed inner cavity through some existing processes during the processing. However, this method of filling the hot melt portion is difficult to handle. Therefore, in a more preferred scheme, the filling space can be a blind hole, and can conveniently fill the hot melt portion into the blind hole, and the hot melt portion can be melted into liquid after the blind hole is heated, so that the edge portion 112 can be heated, and the edge portion 112 is easy to deform.

Generally, one end of the blind hole is open, although the opening can facilitate filling of the hot melting part, after the hot melting part is heated and melted into a liquid state, the liquid hot melting part is easily poured out or leaked from the opening, and in order to prevent the risk, a plug or a sealing layer can be arranged at the opening of the blind hole, so that the hot melting part is better arranged in the blind hole.

Specifically, the key 200 has a structure that is installed in cooperation with the device housing 100, and also has a structure that can trigger a function button of the electronic device, so in a preferred embodiment, the device housing 100 may be provided with an accommodating space 130 and a second mounting hole 140 communicating with the accommodating space 130, the mounting space 110 is isolated from the accommodating space 130, the key main body 210 may further include a key cap 212 and a key post 213 fixed on the key cap 212, and at least a portion of the key post 213 may extend into the accommodating space 130 through the second mounting hole 140, which enables the key 200 to stably and reliably trigger the function button of the electronic device, thereby implementing a key function of the electronic device.

However, since the key 200 has a certain displacement motion, a fitting gap exists between the key 200 and other components, and the fitting gap needs to be sealed in order to prevent foreign substances (e.g., liquid, dust) from entering the inside of the device case 100 through the fitting gap to cause malfunction of the electronic device. In a preferable scheme, a sealing groove portion 2131 may be formed in the key post 213, a sealing sleeve 300 may be sleeved on the sealing groove portion 2131, the sealing sleeve 300 is in sealing fit with the hole wall of the second mounting hole 140, sealing gaps may be sealed between the sealing sleeve 300 and the sealing groove portion 2131 and between the sealing sleeve 300 and the second mounting hole 140 through tight fit, so that a situation that a foreign object enters the inside of the device housing 100 through the matching gaps to cause a functional failure of the electronic device may be avoided, and further, reliability of the electronic device may be improved.

Specifically, the types of the sealing sleeves 300 can be various, and are classified from the perspective of different materials, and the sealing sleeves 300 can be rubber sealing sleeves, flexible plastic sealing sleeves or nylon sealing sleeves and the like; the sealing sleeve 300 may have a U-shaped sealing sleeve, an O-shaped sealing sleeve, or a Y-shaped sealing sleeve, etc., classified from the viewpoint of different structures. In a preferred scheme, the sealing sleeve 300 may be a silica gel sleeve, because the silica gel sleeve has good heat resistance, is non-toxic and odorless, does not produce harmful substances, has good tensile resistance, and can better seal a fit gap.

The flexible contact portions 2133 may be sleeved on the end portions of the key posts 213, or the flexible contact portions 2133 may be disposed on the end portions of the key posts 213 by means of glue dispensing.

As described above, the flexible contact portions 2133 are connected to the end portions of the hard base portions 2132 by injection molding, but the area of the end portions of the hard base portions 2132 is small, so that the flexible contact portions 2133 are less effectively connected to the hard base portions 2132, and there is a risk of dropping. Therefore, in order to make the connection between the flexible contact portions 2133 and the hard base portion 2132 more secure, in a preferable embodiment, the end surface of the hard base portion 2132 may be provided with a glue groove 2134, the flexible contact portions 2133 are injection-molded with the hard base portion 2132, and a part of the flexible contact portions 2133 are fixed in the glue groove 2134, the glue groove 2134 can increase the contact area between the flexible contact portions 2133 and the hard base portion 2132, so that the flexible contact portions 2133 can be more securely disposed at the end portion of the hard base portion 2132, and the reliability of the structure of the key 200 is further mentioned.
