[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In order to better illustrate this application, the following Figure 1 and Figure 2 The coordinate system shown, wherein the Z axis represents the thickness direction of the frame, the X axis may represent the length direction (or width direction) of the frame, and the Y axis represents the width direction (or length direction) of the frame.

[0023] In the embodiment of the present application, the electronic device may be a folding screen electronic device, and the folding screen electronic device includes a first housing portion and a second housing portion. The first housing portion may be understood as a housing portion that carries the secondary screen, and the second housing portion may be understood as a housing portion that carries the primary screen. Currently, the thickness of the first generation of folding screen electronic devices is relatively thick, and the design of the mute key structure on the side of the first housing will not be greatly restricted. Figure 1As shown, the mute key structure mainly includes: a frame 10', a key cap 201', an elastic member 202', a limit member 203' and a rotating member 204'. A third opening 104' adapted to the limit member 203' is provided on the first side of the frame 10', and a blind hole 50' is provided on the second side of the frame 10', and the blind hole 50' is connected to the third opening 104'.

[0024] Optionally, during assembly, first directly insert the elastic member 202' into the bottom of the blind hole 50'; then install the limit member 203' so that the limit slot 2031' of the limit member 203' is aligned with the blind hole 50', then insert the steel ball from the blind hole 50' and pass through the limit slot 2031' to be located between the limit member 203' and the elastic member 202'; then insert the key cap 201' into the blind hole 50'; finally fix the limit member 203' and the key cap 201' by the latch 205'. Optionally, the rotating member 204' is a steel ball made of stainless steel.

[0025] In order to realize the thinness and lightness of electronic devices in the second generation of folding screen electronic devices, it is necessary to reduce the size of the button cap 201'. However, in order to ensure the stability of the side button, it is necessary to ensure that the size of the elastic member 202' remains unchanged. For this purpose, the electronic device of the present application is proposed.

[0026] See also Figure 2 , the present application embodiment provides an electronic device, such as Figures 2 to 10 As shown, the electronic device in the embodiment of the present application includes: a frame 10 and a key assembly;

[0027] The frame 10 includes a first side surface 10a and a second side surface 10b, wherein the second side surface 10b is exposed on the outer surface of the electronic device, a mounting groove 101 is provided in the frame 10, a first opening 102 is provided on the first side surface 10a, and a second opening 103 is provided on the second side surface 10b, wherein the first opening 102 and the second opening 103 are both connected to the mounting groove 101;

[0028] The button assembly includes a button cap 201 and an elastic member 202. The button cap 201 is disposed in the second opening 103. The elastic member 202 is disposed in the mounting groove 101. The first opening 102 is provided with a sliding cover 30. The sliding cover 30 is detachably connected to the frame 10.

[0029] The projection size of the elastic member 202 on the first side surface 10a is smaller than the size of the first opening 102 , and the projection size of the elastic member on the second side surface 10b is larger than the size of the second opening 103 .

[0030] In the embodiment of the present application, the electronic device may be a mobile terminal such as a mobile phone or a tablet. When the electronic device is a mobile phone, the frame 10 may be understood as a middle frame, which generally includes an outer frame and an inner frame. In the embodiment of the present application, the outer frame and the inner frame are regarded as a whole, namely, the frame 10.

[0031] Optionally, the sliding cover 30 can be fixed in the first opening 102 by a drawer-type structure or by a buckle or a thread. The button cap 201 generally includes a connecting portion 2011 and a pressing portion 2012, wherein the pressing portion 2012 is partially exposed outside the frame 10, so that the user can apply a pressing force. The radial cross-section dimensions of the connecting portion 2011 and the pressing portion 2012 in the second opening 103 can be the same or different.

[0032] It should be noted that the projection size of the elastic member 202 on the first side surface 10a is smaller than the size of the first opening 102, which can be understood as: the diameter of the circumscribed circle corresponding to the projection of the elastic member 202 on the first side surface 10a is smaller than the aperture (or minimum aperture) of the first opening 102, or in other words, the projection of the elastic member 202 on the first side surface 10a is located in the opening formed by the first opening 102 on the first side surface 10a, that is, the elastic member 202 can be installed in the installation groove 101 through the first opening 102. Since the first opening 102 is provided on the first side surface 10a of the frame body 10 for the elastic member 202 to be installed in the installation groove 101, the size of the second opening 103 on the second side surface 10b can be reduced, so that while ensuring the stability of the key, the size of the frame body 10 can be reduced, which is conducive to the miniaturization design of the electronic device.

[0033] It should be understood that the projection size of the elastic member 202 on the second side surface 10b is larger than the size of the second opening 103, which can be understood as: the diameter of the circumscribed circle corresponding to the projection of the elastic member 202 on the second side surface 10b is smaller than the aperture (or minimum aperture) of the second opening 103, or in other words, the projection of the elastic member 202 on the second side surface 10b is located within the opening formed by the second opening 103 on the second side surface 10b, that is, the elastic member 202 cannot pass through the second opening 103.

[0034] In the embodiment of the present application, a first opening 102 is provided on the first side 10a of the frame 10, a sliding cover 30 is provided on the first opening 102, a second opening 103 is provided on the second side 10b of the frame 10, and the projection size of the elastic member 202 on the first side 10a is smaller than the size of the first opening 102, and the projection size of the elastic member on the second side is larger than the size of the second opening, so that the elastic member can be directly installed into the mounting groove from the first opening. In this way, when reducing the size design of the second opening, it is not necessary to reduce the size design of the elastic member. Therefore, in the embodiment of the present application, the light and thin design of the electronic device can be achieved while ensuring the stability of the side button.

[0035] Optionally, in some embodiments, the sliding cover 30 includes a sliding cover body 301 and at least two sliding protrusions 302 disposed on the sliding cover body 301, the sliding cover body 301 and the sliding protrusions 302 are located in the first opening 102, and the sliding protrusions 302 can move between a first position and a second position;

[0036] When the sliding protrusion 302 is located at the first position, the sliding protrusion 302 abuts against the inner wall of the first opening 102 , and when the sliding protrusion 302 is located at the second position, the sliding protrusion 302 can be removed from the first opening 102 .

[0037] In the embodiment of the present application, the sliding protrusion 302 can move in the first opening 102, for example, a drawer-type sliding structure. The drawer-type sliding structure is used to install the sliding cover 30 in the first opening 102, so that the sliding cover 30 can be easily disassembled and assembled, and subsequent maintenance is convenient.

[0038] It should be noted that the position and number of the sliding protrusions 302 can be set according to actual needs. For example, in some embodiments, Figure 3 and Figure 4 As shown, two sliding protrusions 302 are arranged at intervals on the first side of the sliding cover body 301, and two sliding protrusions 302 are arranged at intervals on the second side of the sliding cover body 301. The first opening 102 is provided with a first recessed portion 1021 adapted to one of the sliding protrusions 302 on the first side of the sliding cover body 301 and a second recessed portion 1022 adapted to one of the sliding protrusions 302 on the second side of the sliding cover body 301. A first protruding portion 1023 is formed between the first recessed portion 1021 and the third opening 104 provided on the first side surface 10a, and the two sliding protrusions 302 on the first side of the first protruding portion 1023 are adapted; a second protruding portion 1024 is formed between the second recessed portion 1022 and the third opening 104, and the second protruding portion 1024 is adapted to the two sliding protrusions 302 on the second side.

[0039] In the embodiment of the present application, the above-mentioned sliding protrusions 302 can be arranged in parallel and at intervals along the sliding cover body 301. The sliding protrusions 302 can be first aligned with the first recessed portion 1021, the second recessed portion 1022 and the third opening 104; then the sliding cover body 301 is sent into the first opening 102, so that the sliding cover body 301 is partially arranged in the first opening 102 and partially arranged in the third opening 104. Then, the sliding cover body 301 is pushed to slide toward the inside of the first opening 102, so that the sliding cover body 301 is located in the first opening 102. At this time, each sliding protrusion 302 is respectively abutted against the inner wall of the first opening 102, wherein the sliding protrusions 302 close to the third opening 104 are respectively arranged corresponding to the first protrusion 1013 and the second protrusion 1014.

[0040] Since two sliding protrusions 302 are provided on two opposite sides of the sliding cover body 301, the stability of the sliding cover body 301 installed in the first opening 102 can be improved. Of course, in other embodiments, one sliding protrusion 302 can be provided on each side of the sliding cover body 301, so that the first recessed portion 1021 and the second recessed portion 1022 are not required.

[0041] Alternatively, if Figure 5 As shown, in some embodiments, a pressing plate 303 is provided on the surface of the sliding cover body 301 facing the installation slot 101 , and the surface of the pressing plate 303 facing the installation slot 101 forms an arc-shaped concave surface 3031 adapted to the elastic member 20 .

[0042] In the embodiment of the present application, the elastic member 20 may be a spring. Providing the arc-shaped concave surface 3031 may better accommodate the elastic member 20 in the installation groove 101 and allow the elastic member 20 to freely extend and retract in the installation groove 101 .

[0043] Optionally, in some embodiments, a third recessed portion 3011 is provided on a side of the sliding cover body 301 away from the mounting groove 101 .

[0044] In the embodiment of the present application, the third recessed portion 3011 is used as a force point for the tweezers during assembly or disassembly. The specific structure of the third recessed portion 3011 can be set according to actual needs and is not further limited here. Since the third recessed portion 3011 is set, it is more convenient to disassemble and assemble the sliding cover 30.

[0045] Optionally, in some embodiments, the elastic member 202 is a spring, the width of the second opening 103 in the first direction is smaller than the outer diameter of the spring, the first direction is the direction from the first side surface 10a to the third side surface of the frame body 10, and the first side surface 10a and the third side surface are arranged back to back.

[0046] In the embodiment of the present application, the width of the second opening 103 in the first direction is smaller than the outer diameter of the spring, which can be understood as the width of the portion of the second opening 103 used to accommodate the connecting portion 601 in the first direction is smaller than the outer diameter of the spring. Of course, in some embodiments, the thickness of the key cap 201 in the first direction is substantially the same, that is, the width of the second opening 103 in the first direction is also substantially the same, and in this case, the width of the second opening 103 in the first direction is smaller than the outer diameter of the spring, which can be understood as the width of the second opening 103 at any position in the first direction.

[0047] It should be understood that in other embodiments, the elastic member may also adopt other structures, such as a metal spring or other structure with elastic deformation.

[0048] Optionally, in some embodiments, the first side surface 10a is further provided with a third opening 104, the third opening 104 is respectively connected with the first opening 102 and the mounting groove, and the button assembly further includes a limiting member 203 and a rotating member 204;

[0049] The limiting member 203 is disposed in the third opening 104, the limiting member 203 is detachably fixedly connected to the button cap 201, and a limiting through groove 2031 for connecting the mounting groove 101 and the second opening is provided on the limiting member 203;

[0050] The rotating member 204 is disposed between the elastic member 202 and the limiting member 203 .

[0051] During installation, firstly, the elastic member 202 is passed through the first opening 102 and placed in the installation groove 101 to form a Figure 6 Then the slide cover 30 is installed in the first opening 102, and the slide cover 30 presses the elastic member 202 to form a Figure 7 Then the rotating member 204 is inserted into the limiting groove 401 of the limiting member 203, for example, by means of a colloidal oil initially fixed in the limiting groove 401 of the limiting member 203, as specifically Figure 8 As shown, the limiting member 203 is then inserted into the second groove so that the limiting through groove 401 corresponds to the second opening 103 and the mounting groove 101, forming a Fig. 9 Then the key cap 201 is inserted into the second opening 103, and inserted into the limiting groove 401 through the second opening 103 to push the rotating member 204 into the mounting groove 101, forming a Fig.10 The structure shown in FIG. 1 (of course, in some embodiments, the rotating member 204 can be pushed into the mounting groove 101 by other workpieces before the key cap 201 is inserted); finally, the key cap 201 is fixed to the stopper 203 to form a structure as shown in FIG. Fig.11The structure shown.

[0052] It should be understood that when no external force is applied, the elastic force of the elastic member 202 pushes the limiting member 203 and the key cap 201 to move away from the elastic member 202, so that the limiting member 203 is in the initial position (such as Fig.12 As shown in FIG. 2 ), when the user applies force to push the key cap 201 to move, the key cap 201 will push the limiting member 203 to move toward the elastic member 202 and compress the elastic member 202. At this time, the limiting member 203 can be in the target pushing position (as shown in FIG. 2 ). Fig.13 When the user releases the force applied to the key cap 201, the elastic restoring force of the elastic member 202 causes the limiting member 203 to move from the target pushing position to the initial position (as shown in FIG. Fig.12 shown).

[0053] It should be noted that the key function can be realized by detecting the position of the limiter 203 or the key cap 201. For example, a metal conductive structure can be provided on the limiter 203 or the key cap 201, and the key function can be realized by providing a corresponding detection circuit on the frame 10 and the main board of the electronic device. A Hall device can also be provided on the limiter 203 or the key cap 201, a Hall detection element can be provided on the frame 10, and a corresponding detection circuit can be provided on the main board of the electronic device to be electrically connected to the Hall detection element, so that the position information of the Hall device can be detected, thereby realizing the key function. The realization of the specific key function can refer to the relevant technology and is not further limited here.

[0054] Optionally, the button formed by the above-mentioned button assembly can be called a power button for turning on and off the machine, a mute button for one-touch muting, or a volume button for adjusting the volume.

[0055] Optionally, in some embodiments, the rotating member 204 is a sphere.

[0056] Since a sphere is used as a contact member between the elastic member 202 and the limiting member 203 and the key cap 201 , the rotation flexibility can be improved and the stability of the movement of the limiting member 203 can be ensured.

[0057] Optionally, in some embodiments, the sphere is made of polyformaldehyde (POM) material.

[0058] In the embodiment of the present application, the rotating member 204 made of POM material can be called a plug steel ball. Since the movable ball is made of POM material, compared with the steel ball made of stainless steel, the embodiment of the present application can avoid the problem of key jamming caused by wear at the position where the key cap 201 abuts the rotating member 204.

[0059] Optionally, in some embodiments, the inner wall of the limiting through groove 401 is provided with an avoidance groove 20311 adapted to the rotating member 204 , and the avoidance groove 20311 is used to provide an avoidance space when the rotating member 204 is installed.

[0060] In the embodiment of the present application, avoidance grooves can be provided on both opposite inner walls of the position-limiting slot 401, and the avoidance grooves on the opposite inner walls are arranged oppositely, and the avoidance space formed between the two avoidance grooves is slightly smaller than, equal to, or slightly larger than the volume of the rotating member 204, so that the rotating member 204 can be conveniently fixed in the position-limiting slot 401. Therefore, the embodiment of the present application reduces the difficulty of installing the rotating member 204 by providing the avoidance grooves.

[0061] Optionally, in some embodiments, the limiting through slot 401 is provided with a trumpet-shaped opening on one side facing the mounting slot 101 , and the rotating member 204 is partially located in the trumpet-shaped opening.

[0062] In the embodiment of the present application, the inclination of the trumpet-shaped opening can match that of the rotating member 204 , so that the rotating member 204 can be well fixed in the trumpet-shaped opening to prevent the rotating member 204 from moving in the Z-axis direction.

[0063] Optionally, in some embodiments, a portion of the button cap 201 located in the limiting through slot 401 is provided with a first through hole 2013, and a position of the limiting member 203 corresponding to the first through hole 2013 is provided with a second through hole 2032;

[0064] The key assembly further includes a latch 205 , which is inserted into the first through hole 2013 and the second through hole 2032 to fix the limiting member 203 and the key cap 201 .
