[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0043] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0044] like Figure 1 As shown, the embodiment of the present invention provides an electronic device protective shell 100, comprising a shell 10 and a key structure 20 arranged on the shell 10. Figure 1 and Figure 2 The housing 10 has a receiving cavity 13 for receiving the electronic device, and the housing 10 has a key operation area 111. Figure 3 、 Figures 5 to 16 The key structure 20 includes a key body 21 and a signal transmission member 22. The key body 21 includes an operating member 211 and an elastic portion 212. The elastic portion 212 is located on the side of the operating member 211 facing the accommodating cavity 13, and the operating member 211 acts on the elastic portion 212. The key body 21 is provided in the key operation area 111. The signal transmission member 22 is embedded in the key body 21. In a specific embodiment, the signal transmission member 22 is located on the side of the operating member 211 facing the elastic portion 212, that is, the signal transmission member 22 is located on the side of the operating member 211 facing the accommodating cavity 13. One end of the signal transmission member 22 is in contact with the operating member 211, and the other end passes through the elastic portion 212. The function of the operating member 211 and the elastic portion 212 can be understood as that when the operating member 211 is operated or released, the elastic portion 212 can generate elastic deformation to move the signal transmission member 22 and connect or separate with the electronic device button of the electronic device located in the accommodating cavity 13. At the same time, the elastic portion 212 can also restore the signal transmission member 22 to its original state, to avoid the signal transmission member 22 not rebounding after pressing the operating member 211, and jamming the mobile phone button so that the mobile phone button cannot rebound. The signal transmission member 22 is used to connect the contact object outside the accommodating cavity 13 with the electronic device button when connected to the electronic device button. Furthermore, a protective layer can be provided on the surface of the operating member 211. The protective layer can be provided by common processes such as spraying and electroplating. The protective layer can, for example, realize functions such as anti-scratch, anti-fingerprint, anti-fouling, and make the finger slide smoother.

[0045] The housing 10 includes, for example, a side frame 11 and a back panel 12. The side frame 11 and the back panel 12 together enclose a housing cavity 13. When the housing 10 is mounted on an electronic device, the electronic device is located in the housing cavity 13. The housing 10 is made of, for example, TPU or other materials. The specific shape of the housing 10 can be designed with reference to the shape of the corresponding electronic device. The key operation area 111 is an area on the housing 10 corresponding to the keys of the electronic device. For example, for most mobile phones, the keys of the electronic device (such as touch keys) are usually located on the side, and the key operation area 111 is provided on the side frame 11.

[0046] The key structure 20 can be fixedly connected to the housing 10 or detachably connected. The signal transmission component 22 is the key structure of the key structure 20 to realize the operation of the electronic device key. Different forms of signal transmission components 22 can be selected according to different operation trigger conditions of the electronic device key. The contact object outside the accommodating cavity 13 is usually the operator's finger. For example, the key structure 20 needs to electrically connect the finger with the electronic device key. If the transmitted signal is an electrical signal, the signal transmission component 22 is, for example, a conductive column (made of conductive metal or other conductive materials). Of course, if it is necessary to transmit an optical signal, the signal transmission component 22 can be a light guide. The number of signal transmission components 22 can be multiple, and multiple signal transmission components 22 can be respectively connected to different areas of the electronic device key to achieve different conduction effects, such as touch, bipolar, sliding and other operations. The elastic part 212 can be, for example, a material with good elastic deformation, such as elastic foam, spring, shrapnel, silicone, rubber, etc. It deforms after being pressed and recovers after the press is released. Furthermore, the height of the elastic portion 212 after compression should be less than 70% of the original height, so as to better ensure that the signal transmission component 22 is in contact with the mobile phone buttons.

[0047] The working principles of the key structure 20 and the electronic device protective case 100 provided in this embodiment are as follows:

[0048] When the electronic device protective shell 100 is put on the electronic device, the signal transmission component 22 is separated from the electronic device button, and a certain gap is maintained between the two. For example, when the operator holds the mobile phone, even if the skin touches the button body 21, the electronic device button will not be operated because there is no conduction between the signal transmission component 22 and the electronic device button. When it is necessary to operate the electronic device button, such as sliding, double-clicking, etc., the operator's mobile phone will apply a certain force to the button body 21, causing the elastic part 212 to produce elastic deformation. At this time, the signal transmission component 22 moves and connects with the electronic device button. The signal transmission component 22 can connect the operator's finger and the electronic device button to achieve the operation. When the operation is completed and the operator no longer applies pressure on the button body 21, the elastic part 212 resumes its deformation, the signal transmission component 22 moves and separates from the electronic device button, and there is no conduction between the operator and the electronic device button. This can reduce the risk of accidental touch and achieve a certain anti-accidental touch effect.

[0049] In addition, when performing multiple consecutive operations such as double-clicking, according to previous user habits, the user usually does not lift the finger off the electronic device button between the two clicks during the double-click process. In this way, when the user still operates the touch-sensitive button according to habit and does not lift the finger off the button, the finger always remains in contact with the electronic device button and the connection is always maintained, and the double-click effect cannot be achieved. When using the button structure 20 of the electronic device protective case 100 provided in this embodiment, when the user first presses the operating member 211, the elastic portion 212 elastically deforms, causing the signal transmission member 22 to contact and connect with the electronic device button. At this time, the user reduces the pressure applied by the finger but does not lift the finger off the operating member 211. The elastic portion 212 recovers its deformation, causing the signal transmission member 22 to separate from the electronic device button. After pressing again, the signal transmission member 22 contacts and connects with the electronic device button again. During this process, the signal transmission member 22 is connected, disconnected, and then connected again with the electronic device button, achieving a double-click effect.

[0050] In some embodiments, reference Figure 3 A recess 113 is formed on the side of the key operation area 111 facing the accommodating cavity 13. The operating member 211 is integrally formed with the housing 10 and forms the bottom wall of the recess 113. The elastic portion 212 is located within the recess 113, and the signal transmission member 22 is also located within the recess 113. This prevents the elastic portion 212 and the signal transmission member 22 from being exposed to the outside, preventing dust contamination and corrosion from sweat.

[0051] In some embodiments, the elastic portion 212 can be made of a material such as foam, and the signal transmission member 22 is embedded in the elastic portion 212. At least one end of the signal transmission member 22 near the accommodating cavity 13 can extend outside the elastic portion 212 as the elastic portion 212 elastically deforms. For example, when not in use, the end of the signal transmission member 22 near the accommodating cavity 13 is located within the elastic portion 212. When an operator performs such an operation, the finger touches the housing 10 (i.e., touches the operating member 211) from the bottom wall of the groove 113 away from the accommodating cavity 13. The pressure is transmitted to the elastic portion 212, causing the elastic portion 212 to deform, such as being compressed. At this time, the end of the signal transmission member 22 near the accommodating cavity 13 is exposed from the elastic portion 212, thereby contacting the electronic device button. Of course, when not in use, the end of the signal transmission member 22 near the accommodating cavity 13 can also be exposed outside the elastic portion 212, as long as a gap is maintained between the end and the electronic device button.

[0052] In some embodiments, an operation guide structure 112 is provided on one side of the key operation area 111 away from the accommodating cavity 13. The operation guide structure 112 may be, for example, Figure 3 The slot structure shown may be made of different materials, colors, texts, etc., so that the user can confirm the position of the key structure 20 according to the operation guide structure 112 to perform more accurate operations.

[0053] In some embodiments, the signal transmission member 22 is fixedly connected to the operating member 211. The operating member 211 has the function of fixing the signal transmission member 22. When a user operates the operating member 211, they touch one side of the operating member 211 to achieve contact with the signal transmission member 22. The operating member 211 can be made of a conductive material or a thin material to ensure that the contact object and the signal transmission member 22 can be electrically connected through the operating member 211.

[0054] In some embodiments, there are multiple signal transmission elements 22, and the multiple signal transmission elements 22 are spaced apart from each other. Figure 4 、 Figure 5 The elastic part 212 is sleeved on one or more parts of the signal transmission element 22. Or the elastic part 212 is located between two adjacent signal transmission elements 22. The elastic part 212 sleeved with multiple signal transmission elements 22 can be a plurality of elastic parts or can be connected into one. For example, refer to Figure 8 , corresponding to some of the signal transmission members 22 in the plurality of signal transmission members 22, springs are provided as elastic parts 212, and each spring is provided with a signal transmission member 22. The elastic parts 212 located between adjacent signal transmission members 22 in the plurality of signal transmission members 22 can be provided separately or connected as one. Figure 5 and Figure 6 The elastic portion 212 shown in FIG can be considered as being provided on the signal transmission member 22 or being provided in the gap between adjacent signal transmission members 22. It can also be considered that a plurality of through holes are provided on the elastic portion 212, and a plurality of signal transmission members are respectively provided in the plurality of through holes. Figure 5 As shown, it is not necessary to provide an elastic portion 212 corresponding to each signal transmission member 22 .

[0055] In some embodiments, the distance between the end faces of any two signal transmission members 22 among the multiple signal transmission members 22 facing the accommodating cavity 13 is less than or equal to 0.1 mm. That is, the end faces of the multiple signal transmission members 22 facing the accommodating cavity 13 are flush, or the surface where the operating member 211 is connected to the signal transmission member 22 is used as a reference surface, the distance from the end face of the signal transmission member 22 to the reference surface is the height of the signal transmission member 22, and the height difference of the multiple signal transmission members 22 is less than 0.1 mm. This ensures that the end faces of the multiple signal transmission members 22 facing the accommodating cavity 13 remain as flush as possible to ensure the effect of the sliding operation. In some embodiments, the button structure 20 further includes a button connector 23, and the button body 21 is connected to the shell 10 through the button connector 23. The elastic portion 212 is clamped between the operating member 211 and the button connector 23. The button connector 23 can be fixedly or detachably connected to the shell 10. For example, a through hole is provided on the housing 10 corresponding to the key operation area 111, and the key connector 23 can be installed in the through hole of the key operation area 111, and can be installed by clamping, welding, bonding, etc. The key body 21 can be fixedly or detachably connected to the key connector 23.

[0056] In some embodiments, reference Figure 6 The operating member 211 is engaged with the key connecting member 23 , and the elastic portion 212 is sandwiched between the operating member 211 and the key connecting member 23 .

[0057] specifically refer to Figure 5 、 6 and Figure 7 The button connector 23 has a mounting groove 231 . The elastic portion 212 is sandwiched between the bottom wall of the mounting groove and the operating member 211 .

[0058] In some embodiments, the button connector 23 forms a first flange 232 on the inner edge of the mounting slot 231. The operating member 211 and the elastic portion 212 are disposed within the mounting slot 231. The edge of the operating member 211 forms a second flange 2111, and the first flange 232 and the second flange 2111 are mutually engaged. The mounting slot 231 may be, for example, a blind hole, or may be understood as a slot-shaped hole.

[0059] Or in other embodiments, refer to Figure 9 and Figure 10The key connector 23 has a through hole 234, which is specifically arranged on the bottom wall of the mounting groove 231. The end of the signal transmission member 22 away from the operating member 211 can pass through the through hole 234 to connect with the key of the electronic device. Specifically, the signal transmission member 22 includes a main body 221 and a clamping portion 222. The operating member 211 and the elastic portion 212 are located on the side of the key connector 23 facing away from the accommodating cavity 13. The clamping portion 222 is located on the side of the key connector 23 facing the accommodating cavity 13. One end of the main body 221 is connected to the operating member 211, and the other end passes through the through hole 234 to connect with the clamping portion 222. The width of the clamping portion 222 is greater than the width of the through hole 234. For example, when the clamping portion 222 and the through hole 234 are circular, the width of the clamping portion 222 refers to the diameter of the clamping portion 222, and the width of the through hole 234 refers to the diameter of the through hole 234. When there are multiple signal transmission members 22, only some of the multiple signal transmission members 22 may be engaged with the key connector 23. Figure 10 Only the signal transmission members 22 at the two ends are electrically connected to the key connector 23. In some embodiments, the through hole 234, for example, gradually decreases in width as it moves away from the accommodating cavity 13, so that the engaging portion 222 can not only be engaged with the through hole 234 but also be accommodated within the through hole 234, preventing the engaging portion 222 from protruding outside the key connector 23. This ensures that a gap is maintained between the engaging portion 222 and the electronic device key to better prevent accidental touches.

[0060] In other embodiments, the operating member 211 and the elastic portion 212 can be connected to the key connector 23 by bonding, for example, referring to Figure 11 Opposite sides of the elastic portion 212 are bonded to the operating member 211 and the key connector 23 (specifically, the bottom wall of the mounting groove 231), respectively. A first adhesive member 24 is disposed between the elastic portion 212 and the key connector 23, and a second adhesive member 25 is disposed between the elastic portion 212 and the operating member 211, achieving a stable bonding effect. The first adhesive member 24 and the second adhesive member 25 are made of, for example, glue or double-sided tape.

[0061] In some embodiments, reference Figure 14 and Figure 15 When the elastic portion 212 is sandwiched between the operating member 211 and the key connector 23, the operating member 211 may be provided with a third flange 2112 formed on at least two opposite sides of the elastic portion 212 on one side thereof, and the third flange 2112 abuts against the elastic portion 212. Figure 15As shown, the third flange 2112 can be an annular flange. When the third flange 2112 abuts against the elastic part 212, a gap is formed between the part of the operating member 211 located between the two opposite third flanges 2112 and the elastic part 212, so that when the elastic part 212 is deformed, the deformed part can be accommodated in the gap to ensure the deformation effect of the elastic part 212.

[0062] In some embodiments, reference Figure 12 、 Figure 13 and Figure 14 The key connector 23 forms a key receiving groove 233 on the side facing the accommodating cavity 13. When the housing 10 is mounted on the electronic device, the electronic device keys are located within the area enclosed by the notch of the key receiving groove 233. Alternatively, the notch of the key receiving groove 233 is larger than the size of the electronic device keys. Therefore, when the housing 10 is mounted on the electronic device, the edge of the key connector 23 contacts the side of the electronic device and surrounds the electronic device keys, while the bottom wall of the key receiving groove 233 maintains a certain distance from the electronic device keys. The end of the signal transmission member 22 near the accommodating cavity 13 is, for example, flush with the bottom wall of the key receiving groove 233 or located on the side of the bottom wall away from the accommodating cavity 13, thereby ensuring an anti-accidental touch effect. The distance between the end surface of the signal transmission member 22 near the accommodating cavity 13 and the notch of the key receiving groove 233 is, for example, 0.05 to 0.3 mm, which ensures a good anti-accidental touch effect.

[0063] The key structure 20 also includes a protective member 26, which is located on the side of the signal transmission member 22 facing the accommodating cavity 13. In some embodiments, the protective member 26 is connected to the signal transmission member 22 and can move with the movement of the signal transmission member 22. Alternatively, in some embodiments, the protective member 26 is provided at the bottom of the key accommodating groove 233, and the protective member 26 can be deformed as the signal transmission member 22 moves to connect or separate from the electronic device key. The protective member 26 can, for example, be made of the same material as the operating member 211, which can ensure that the signal transmission member 22 can be connected to the electronic device key when in contact with the electronic device key through the protective member 26. The provision of the protective member 26 can cover the signal transmission member 22, which has a more aesthetically pleasing effect.

[0064] In some embodiments, reference Figure 16 The elastic portion 212 is a spring sheet connected to the operating member 211, with opposite ends of the spring sheet embedded in the housing 10. The housing 10 is provided with, for example, mounting portions 114. The spring sheet extends, for example, along the length of the operating member 211. The ends of the spring sheet extending beyond the operating member 211 are clamped by the mounting portions 114 on the side frame 11. This allows the key body 21 to assume a concave shape when the operating member 211 is pressed, gradually approaching and contacting the electronic device key, ultimately achieving a conductive effect.
