[0002] With the continuous development of science and technology, the popularity of electronic devices such as mobile phones and tablet computers is constantly increasing. People often carry mobile phones in their daily lives. However, since electronic devices cannot avoid bumping and falling when in use, and electronic devices are easily damaged by bumping and falling, in order to protect electronic devices, a protective shell is provided in the prior art to protect electronic devices. At the same time, in order to facilitate the operation of relevant functions of the mobile phone, mechanical buttons are generally set on the side of the mobile phone, and the mobile phone is controlled by pressing the buttons. For example, the power button can control the screen off, screen on, unlock or switch the mobile phone, and the volume button can control the increase or decrease of the volume of the mobile phone. Correspondingly, when the mobile phone is set with a protective shell, in order to ensure the normal use of the relevant buttons, buttons are generally set at the corresponding positions on the protective shell to realize the control of the mechanical buttons on the side of the mobile phone. With the continuous development of technology, the side buttons of the mobile phone are also continuously upgraded from mechanical button structures to touch-type and inductive buttons. Since touch-type and inductive buttons require human fingers to directly contact the buttons for operation, the existing button structure can no longer meet the upgraded mobile phone structure.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1 and Figure 2 , an embodiment of the utility model provides a key structure 100, and the key structure 100 may, for example, include a key body 110 and a conductive medium 120. The conductive medium 120 is connected to the key body 110, and the conductive medium 120 is used to electrically connect two objects that are in contact with the inner surface and the outer surface of the key body 110. The inner surface of the key body 110 may, for example, be a surface that contacts a key of an electronic device, and the outer surface of the key body 110 may, for example, be a surface that contacts a finger of a user. Through such a setting, when the user touches the key body 110 with a finger, the conductive medium 120 can electrically connect the finger with the mobile phone key on the inner surface of the key body 110, so that the user can adapt to the upgraded touch key through the key structure 100, and can also adapt to the old mechanical key, which solves the problem that the existing key structure cannot adapt to the inductive key on the electronic device.

[0035] Specifically, one end of the conductive medium 120 may be connected to the inner surface of the key body 110, and the other end may be connected to the outer surface of the key body 110, so as to realize electrical connection between two objects in contact with the inner surface and the outer surface of the key body 110. In one implementation of this embodiment, the conductive medium 120 may be disposed on the side of the key body 110, and then one end of the conductive medium 120 may be connected to the inner surface of the key body 110, and the other end may be connected to the outer surface of the key body 110.

[0036] In another implementation of the present embodiment, the conductive medium 120 may also be embedded in the key body 110, and the conductive medium 120 protrudes from the inner surface and / or outer surface of the key body 110, so that the two objects that are in contact with the inner surface and the outer surface of the key body 110 can be electrically connected through the conductive medium 120. Specifically, the key body 110 may be provided with a through hole 111, and the conductive medium 120 is embedded in the through hole 111. In some implementations, there may be, for example, a plurality of through holes 111, and there may also be, for example, a plurality of conductive media 120, and a plurality of conductive media 120 are embedded in a plurality of through holes 111. In the present embodiment, the through hole 111 and the conductive medium 120 may both be, for example, circular, and of course, they may also be, for example, other shapes, and the present embodiment is not limited thereto.

[0037] See also Figure 3 In another implementation of this embodiment, the key body 110 may be provided with a through hole 111, the conductive medium 120 may be provided on the side wall of the through hole 111, and the conductive medium 120 may protrude from the inner surface and / or outer surface of the key body 110, so that the two objects in contact with the inner surface and the outer surface of the key body 110 can be electrically connected through the conductive medium 120. The conductive medium 120 may be applied on the side wall of the through hole 111, for example, by copper deposition or electroplating, and the conductive medium may also be applied on the inner surface and / or outer surface of the key body 110 surrounding the through hole 111; of course, the conductive medium 120 may be attached to the side wall of the through hole 111, for example, but this embodiment is not limited thereto.

[0038] See also Figure 4AThe conductive medium 120 may, for example, include a first conductive medium 121 and a second conductive medium 122. The first conductive medium 121 is disposed on the inner surface of the key body 110, and the second conductive medium 122 is disposed on the outer surface of the key body 110. The first conductive medium 121 is electrically connected to the second conductive medium 122. The first conductive medium 121 and the second conductive medium 122 may, for example, be electrically connected through the conductive medium. The materials of the first conductive medium 121, the second conductive medium 122 and the conductive medium may, for example, be the same. When the user operates the key structure, the conductive medium may electrically connect the user's finger to the mobile phone key, so that the key structure can adapt to the upgraded touch key, and can also adapt to the old mechanical key, which solves the problem that the existing key structure cannot adapt to the inductive key on the electronic device. In some implementations of this embodiment, the size of the first conductive medium 121 may be, for example, the same as the inner surface of the key body 110, and the first conductive medium 121 may be, for example, attached to the inner surface of the key body 110. Similarly, the size of the second conductive medium 122 may be, for example, the same as the outer surface of the key body 110, and the second conductive medium 122 may be, for example, attached to the outer surface of the key body 110. In another implementation of this embodiment, the size of the first conductive medium 121 may be, for example, different from the inner surface of the key body 110, that is, the first conductive medium 121 may, for example, partially cover the key body 110, and / or the size of the second conductive medium 122 may be, for example, different from the outer surface of the key body 110, that is, the second conductive medium 122 may, for example, partially cover the key body 110.

[0039] See also Figure 4B , the key body 110 may be provided with a connection through hole, and the conductive medium 120 may include a conductive layer 123 and a conductive protrusion 124 that are electrically connected to each other. The conductive layer 123 is provided on the outer surface of the key body 110, and the conductive protrusion 124 is embedded in the connection through hole and exposed on the inner surface of the key body 110. The conductive layer 123 can contact with the user's finger, and the conductive protrusion 124 can contact with the key of the electronic device, so that the conductive medium 120 can electrically connect the user's finger with the mobile phone key when the user operates the key structure 100.

[0040] See also Figure 5 and Figure 6The key body 110 may, for example, include a plurality of key portions 112 arranged at intervals, and the key body 110 may be arranged as a plurality of key portions 112 arranged at intervals. The plurality of key portions 112 may, for example, include two key portions 112 or more than two key portions 112, and the specific number may be set according to actual needs. In this way, the keys on the electronic device may be partially controlled by the key structure 100, and different functions may be realized when different positions on the keys on the electronic device are controlled. The plurality of key portions 112 arranged at intervals may be adapted to control different parts to realize different functional controls. Each key portion 112 is connected to a conductive medium 120, and any two adjacent key portions 112 are separated by an insulating medium, so that when a user operates a key portion 112 on the key structure 100, the conductive medium 120 may electrically connect the user's finger to the mobile phone key, and will not cause the operation to affect other key portions 112, so as to improve the accuracy of the operation.

[0041] See also Figure 7 The utility model also provides a key structure 100. The key structure 100 may include, for example, a conductive medium layer 101 and a first adhesive layer 102 that are stacked, and the conductive medium layer 101 is connected to the first adhesive layer 102. By setting the first adhesive layer 102, the key structure 100 can be connected to the keys on the electronic device, thereby improving the connection stability between the key structure 100 and the keys on the electronic device, and preventing the key structure 100 from being separated from the electronic device and affecting the key effect. In addition, the conductive medium layer 101 can realize the electrical connection between the user's fingers and the keys on the electronic device. When the user operates the key structure 100, the conductive medium 120 can electrically connect the user's fingers to the mobile phone keys, so that the key structure 100 can adapt to the upgraded touch keys, and can also adapt to the old mechanical keys, solving the problem that the existing key structure 100 cannot adapt to the inductive keys on the electronic device.

[0042] See also Figure 8, the key structure 100 may, for example, further include a PET layer 103, the PET layer 103 is connected to the first adhesive layer 102, the conductive medium layer 101 and the PET layer 103 are respectively located on both sides of the first adhesive layer 102, the conductive medium layer 101 may, for example, be located on the outside of the key structure 100, and the PET layer 103 may, for example, be located on the inside of the key structure 100, of course, this embodiment is not limited thereto. PET is polyethylene terephthalate (PET), and PET may, for example, be a resin, which has excellent physical and mechanical properties in a wide temperature range, and the use temperature can reach 120°C, and the electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, and it has good creep resistance, fatigue resistance, friction resistance and dimensional stability. In a specific embodiment, the thickness of the PET layer can be set according to different materials. When the thickness of the PET layer is small, when the user operates the key structure 100, the conductive medium layer 101, the first adhesive layer 102 and the PET layer 103 can electrically connect the user's fingers with the mobile phone keys, so that the touch keys or induction keys can be operated through the key structure 100.

[0043] See also Fig. 9 The embodiment of the utility model further provides a protective shell 10, which may, for example, include a shell and the key structure 100 as described above. The shell 100 may, for example, include a back plate 210 and a side frame 220, the back plate 210 and the side frame 220 are connected, the side frame 220 and the back plate 210 may, for example, be integrally formed, and the back plate 210 and the side frame 220 enclose an electronic device accommodating cavity. The electronic device accommodating cavity is used to accommodate electronic devices, and the back plate 210 and the side frame 220 can protect the electronic device so that the electronic device is not easily damaged when it falls. When an electronic device, such as a mobile phone, is accommodated in the electronic device accommodating cavity of the protective shell 10, the back plate 210 is attached to the back of the mobile phone away from the screen, and the back plate 210 can be used to prevent the back of the electronic device from being scratched by the desktop when the electronic device is placed on the desktop, etc. The size of the back plate 210 may, for example, be substantially consistent with the size of the back of the electronic device.

[0044] The key structure 100 is connected to the shell, and specifically can be connected to the side frame 220, or can be connected to the back plate 210. In some implementations of this embodiment, the key structure 100 and the shell can be integrally formed, for example; the key structure 100 can also be connected to the shell in combination, for example, that is, the key structure 100 and the shell are two components, and the key structure 100 can be connected to the shell by, for example, pasting, riveting or clamping. Of course, this embodiment is not limited to this. The protective shell 10 provided in this embodiment is provided with the key structure 100, so that the user key structure 100 can transmit the operation instruction to the inductive key to realize the operation of the inductive key. The protective shell 10 of this embodiment can not only adapt to the upgraded touch key, but also adapt to the old mechanical key, which solves the problem that the key structure on the existing protective shell 10 cannot adapt to the inductive key on the electronic device. In one implementation of this embodiment, the shell can be provided with a key through hole 221, for example, and the key structure 100 can be clamped in the key through hole 221.

[0045] In one implementation of this embodiment, see Fig.10 For example, the shell may be provided with a key through hole 221 and a connecting side wall 222 surrounding the key through hole 221, and the key structure 100 is adhered to the connecting side wall 222 through the second adhesive layer 230 to connect the key structure 100 to the shell.

The edge of the inner side wall of the key structure 100 may be provided with a third adhesive layer 223, for example, and the third adhesive layer 223 is used to adhere the key structure 100 to the key or side of the electronic device. When the protective shell 10 is sleeved on the electronic device, the third adhesive layer 223 may be adhered to the key of the electronic device or the side of the key, so as to improve the connection stability between the key structure 100 and the key of the electronic device.
