[0003] Among them, shoulder keys are usually set to enhance the user experience of mobile phone games. In related technologies, mobile phone shoulder keys include capacitive keys and mechanical lifting keys. Capacitive keys have better integrity and waterproof and dustproof effects for mobile phones; mechanical lifting keys have a more real touch, but the consistency of the mobile phone appearance is poor, affecting the overall aesthetics of the mobile phone. Currently, neither of these two types of keys can balance the consistency of the mobile phone appearance and meet the requirement of pressing touch, and the overall experience needs to be improved. Summary of the Invention

[0004] This application aims to provide an electronic device, at least solving the problem that the shoulder keys on mobile phones in related technologies cannot balance the consistency of the mobile phone appearance and the pressing touch.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of this application provides an electronic device, including:

[0007] A middle frame, on a first side surface of the middle frame, there is an installation hole;

[0008] A key assembly, including a key, a slider and a plunger that are sequentially abutted against each other in the axial direction of the installation hole, the key and the plunger are movably arranged in the installation hole along the axial direction, one end of the plunger away from the key is adapted to abut against a key switch, and the slider is slidably arranged on the middle frame;

[0009] A reset assembly, arranged on the middle frame;

[0010] Wherein, the slider has a first position and a second position relative to the middle frame. When the slider is in the first position, the slider presses the key so that a part of the key extends out of the installation hole; when the slider is in the second position, the key retracts into the installation hole under the action of the reset assembly.

[0011] In an embodiment of the present application, a slider that can move relative to the middle frame is provided between the button and the plunger. When the slider moves to the first position, the slider can squeeze the button to make the button in the extended state to meet the pressing requirement; when the slider moves to the second position, the reset component is used to drive the button to retract into the mounting hole, so that the button is in the hidden state, and the appearance of the electronic device has better consistency, and the accidental touch of the button is avoided. In the embodiment of the present application, the relative distance between the plunger is changed by the movement of the slider and the reset component, so that the button can be switched between the hidden state and the extended state, and the electronic device takes into account both the appearance consistency of the mobile phone and the pressing touch feeling.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] The following will be combined with Figures 1 - 15 Describe an electronic device according to an embodiment of the present application.

[0039] The electronic device proposed in the embodiment of the present application can be an electronic device with keys such as a mobile phone, a tablet computer, a notebook, etc. As Figures 1 - 3 shown, the electronic device proposed in the embodiment of the present application includes a middle frame 1, a key assembly 2, and a reset assembly 3. The reset assembly 3 is arranged in the middle frame 1. An installation hole 11 is provided on the first side surface 101 of the middle frame 1. The key assembly 2 includes a key 21, a slider 22, and a plunger 23 that are sequentially abutted against each other in the axial direction of the installation hole 11. The key 21 and the plunger 23 are movably arranged in the installation hole 11 along the axial direction of the installation hole 11. One end of the plunger 23 away from the key 21 is adapted to abut against the key switch 241. The slider 22 is slidably arranged in the middle frame 1.

[0040] Wherein, the slider 22 has a first position and a second position relative to the middle frame 1. When the slider 22 is in the first position, the slider 22 presses the key 21 so that a part of the key 21 extends out of the installation hole 11. When the slider 22 is in the second position, the key 21 retracts into the installation hole 11 under the action of the reset assembly 3.

[0041] Wherein, the electronic device further includes a button circuit board 24, and a button switch 241 is disposed on the button circuit board 24. A first mounting groove 12 is provided on a second side surface 102 of the middle frame 1 adjacent to the first side surface 101, and the first mounting groove 12 communicates with the mounting hole 11. The button circuit board 24 is disposed in the first mounting groove 12, and one end of the plunger 23 away from the button 21 extends into the first mounting groove 12 and abuts against the button switch 241. A metal elastic sheet is provided in the button switch 241. When the button 21 is pressed, the pressing force is sequentially transmitted through the button 21, the slider 22, and the plunger 23 to the metal elastic sheet, causing the metal elastic sheet to contact the contact on the button circuit board 24, thereby triggering the button function.

[0042] As Figures 9 - 11 shown, the slider 22 is in the first position, the button 21, the slider 22, the plunger 23, and the button switch 241 are sequentially in contact with each other, and a part of the button 21 protrudes from the first side surface 101. At this time, the user can press the button 21 to implement the button function. Wherein, a part of the button 21 protruding from the first side surface 101 means that the surface of the button 21 away from the plunger 23 is higher than the first side surface 101.

[0043] As Figures 12 - 14 shown, the slider 22 is in the second position, the button 21, the slider 22, the plunger 23, and the button switch 241 are sequentially in contact with each other, and the button 21 does not protrude from the first side surface 101. At this time, the first side surface 101 of the middle frame 1 has better appearance consistency. Wherein, the button 21 not protruding from the first side surface 101 means that the surface of the button 21 away from the plunger 23 is flush with or lower than the first side surface 101.

[0044] It can be understood that when the slider 22 switches from the second position to the first position, the slider 22 presses the button 21 outward from the mounting hole 11, increasing the distance between the button 21 and the plunger 23, and the button 21 protrudes from the first side surface 101. When the slider 22 switches from the first position to the second position, the reset assembly 3 drives the button 21 to move inward to the mounting hole 11, reducing the distance between the button 21 and the plunger 23 until the button 21 retracts into the mounting hole 11, hiding the button 21 below the first side surface 101. And during this process, the button 21 and the slider 22 remain in contact with each other, and there is no shaking of the button 21, the slider 22, and the plunger 23.

[0045] According to the electronic device of the embodiment of the present application, by arranging a slider 22 that can move relative to the middle frame 1 between the button 21 and the plunger 23, when the slider 22 moves to the first position, the slider 22 can squeeze the button 21 to make the button 21 in the extended state, meeting the pressing requirement; when the slider 22 moves to the second position, the reset assembly 3 is used to drive the button 21 to retract into the mounting hole 11, making the button 21 in the hidden state. The appearance of the electronic device has better consistency, and the accidental touch of the button 21 is avoided. In the embodiment of the present application, the relative distance between the button 21 and the plunger 23 is changed by the movement of the slider 22 and the reset assembly 3, so that the button 21 can be switched between the hidden state and the extended state, making the electronic device take into account both the appearance consistency of the mobile phone and the pressing touch.

[0046] The button 21 in the embodiment of the present application can be used as a game shoulder button, and the user can adjust the state of the button 21 according to the requirements of different usage scenarios. When a mobile phone game is needed, the slider 22 is moved to the first position; when no mobile phone game is played, the slider 22 is moved to the second position.

[0047] Among them, referring to Figure 12 and Figure 15 , a sealing ring 231, such as a silicone ring, is provided between the plunger 23 and the mounting hole 11. The sealing ring 231 is in interference fit with the inner wall of the mounting hole 11, which can prevent external water from entering the first mounting groove 12 from the mounting hole 11, ensuring that the electronic device has good waterproof airtightness.

[0048] The button 21 is provided with a limiting portion, and the limiting portion is limited within the middle frame 1 to prevent the button 21 from disengaging from the mounting hole 11. For example, the limiting portion of the button 21 includes two hanging platforms 211 respectively arranged on both sides of the button 21, and the middle frame 1 is provided with two connecting holes 16 corresponding to the two hanging platforms 211 one by one, and each hanging platform 211 is located within the corresponding connecting hole 16. A limiting block 5 is arranged within the middle frame 1 and is limited within the middle frame 1 in the axial direction of the mounting hole 11. A part of the limiting block 5 is located between the side of the hanging platform 211 away from the plunger 23 and the middle frame 1 to limit the hanging platform 211 from moving outward toward the connecting hole 16.

[0049] Specifically, the button 21 is provided with a top post 212, and the button 21 is in contact with the slider 22 through the top post 212. The two hanging platforms 211 are symmetrically distributed on both sides of the top post 212. The second side surface 102 is provided with two second mounting grooves 13, the two second mounting grooves 13 are in one-to-one correspondence and communication with the two connecting holes 16, and the two limiting blocks 5 are correspondingly arranged in the two second mounting grooves 13.

[0050] When assembling the key assembly 2 with the middle frame 1, first install the key circuit board 24 in the first installation groove 12 from the second side 102; then install the plunger 23, the slider 22 and the key 21 in the installation hole 11 from the first side 101 in sequence. When installing the key 21, insert the two hanging platforms 211 of the key 21 into the corresponding connecting holes 16, and then install the limit block 5 in the second installation groove 13 from the second side 102.

[0051] In the embodiment of the present application, the movement of the slider 22 can be automatically controlled, for example, the slider 22 is connected to a drive motor, and the drive motor is controlled to drive the slider 22 to move, and the control of the drive motor can be performed by a control program of the electronic device. Alternatively, a portion of the slider 22 is exposed outside the middle frame 1, and the slider 22 is moved directly by manually moving it. Alternatively, the slider 22 is connected to a transmission component, and a portion of the transmission component is exposed outside the middle frame 1, and the slider 22 is driven to move by manually moving the transmission component.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the reset assembly 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is disposed on the button 21, and the second magnet 32 is disposed on the middle frame 1. The first magnet 31 and the second magnet 32 are disposed opposite to each other and have opposite magnetic poles. When the slider 22 switches from the first position to the second position, under the magnetic attraction of the first magnet 31 and the second magnet 32, the button 21 is restricted in the mounting hole 11 in a hidden state, and the button 21 is kept in contact with the slider 22.

[0053] It should be noted that the magnetic attraction of the first magnet 31 and the second magnet 32 is much smaller than the minimum pressing force of the key switch 241, so that the user can clearly feel the resistance of the key switch 241 when pressing the key 21, ensuring the pressing feel of the key 21. At the same time, due to the effect of the magnetic attraction, the key 21, the slider 22 and the plunger 23 can be in close contact, which can prevent the key 21 and the plunger 23 from shaking.

[0054] Specifically, the mounting hole 11 includes a counterbore section 111 and a through-hole section 112 that are connected to each other. The counterbore section 111 communicates with the first side surface 101, and the through-hole section 112 communicates with the counterbore section 111 and the first mounting groove 12. The button 21 includes a pressing portion 213 and a top post 212. The top post 212 is connected to the pressing portion 213, and the pressing portion 213 is for the user to press. The top post 212 is movably disposed in the through-hole section 112 along the axial direction of the mounting hole 11, and the pressing portion 213 is movably disposed in the counterbore section 111 along the axial direction of the mounting hole 11. The first magnet 31 is embedded in the surface of the pressing portion 213 close to the top post 212, and the second magnet 32 is embedded in the bottom of the counterbore section 111. When the button 21 is in the hidden state, under the magnetic attraction of the first magnet 31 and the second magnet 32, the pressing portion 213 is restricted in the counterbore section 111 to prevent the button 21 from protruding out of the mounting hole 11, and keep the button 21 in contact with the slider 22.

[0055] It should be noted that the reset assembly 3 can also be in other structural forms, and the present application does not make specific limitations thereto. For example, the reset assembly 3 includes a reset spring connected between the button 21 and the middle frame 1. When the slider 22 switches from the first position to the second position, the button 21 remains in contact with the slider 22 under the elastic force of the reset spring and moves inward to the mounting hole 11 to the hidden state.

[0056] In some embodiments of the present application, the button 21 is provided with a top post 212, and the button 21 abuts against the slider 22 through the top post 212. The number of the reset assemblies 3 is two, and the two reset assemblies 3 are respectively located on both sides of the top post 212 and are symmetrically arranged. That is to say, the number of the first magnets 31 and the second magnets 32 is both two. The two first magnets 31 are respectively located on both sides of the top post 212 and are symmetrically arranged. The two second magnets 32 are respectively located on both sides of the through-hole section 112 of the mounting hole 11 and are symmetrically arranged. The two first magnets 31 and the two second magnets 32 are arranged in a one-to-one correspondence. In this way, the two sides of the button 21 can receive the same magnitude of magnetic force, making the telescopic movement of the button 21 more stable.

[0057] As Figure 3 、 Figures 6 - 8 shown, the electronic device provided in some embodiments of the present application further includes a transmission assembly 4. The transmission assembly 4 includes a sliding key 41, a connecting rod 42, and a limiting member 43. The limiting member 43 is disposed on the middle frame 1, and the sliding key 41 is slidably disposed on the middle frame 1. One end of the connecting rod 42 is connected to the slider 22, and the other end is connected to the sliding key 41.

[0058] Specifically, the sliding key 41 has a third position and a fourth position relative to the middle frame. The third position is closer to the button assembly 2 than the fourth position. When the sliding key 41 moves between the third position and the fourth position, the slider 22 is driven to move between the first position and the second position through the connecting rod 42.

[0059] When the sliding key 41 slides to the third position, the slider 22 switches to the first position, and the limiting member 43 limits the sliding key 41 to the third position; when the sliding key 41 is in the fourth position, the slider 22 switches to the second position, and the limiting member 43 limits the sliding key 41 to the fourth position. Without external force, the sliding key 41 can remain in the third position or the fourth position; under the action of external force, the sliding key 41 can resist the restriction of the limiting member 43 and switch between the third position and the fourth position.

[0060] Optionally, a sliding groove 15 is further provided on the first side surface 101, and the sliding key 41 is slidably arranged in the sliding groove 15. The sliding key 41 protrudes slightly from the first side surface 101 for easy sliding. Alternatively, the sliding key 41 may not protrude from the first side surface 101, that is, the surface of the sliding key 41 away from the sliding groove 15 is flush with or lower than the first side surface 101, and uneven indentations are provided on the surface of the sliding key 41 to improve the feel. When both the key 21 and the sliding key 41 are flush with the first side surface 101, the first side surface 101 has an integrated appearance.

[0061] By providing the above-mentioned transmission assembly 4 in the embodiment of the present application, there is no need for external drive motors, gear racks or screw drives and other mechanisms. The transmission assembly 4 can be arranged in the middle frame 1 without increasing the thickness of the whole machine, ensuring the thin and light characteristics of the whole machine.

[0062] See Figures 6 - 8 , in some embodiments of the present application, the limiting member 43 includes a third magnet 431, a fourth magnet 432 and a fifth magnet 433. The third magnet 431 is arranged on the sliding key 41, and the fourth magnet 432 and the fifth magnet 433 are arranged on the middle frame 1. Among them, when the sliding key 41 is in the third position, the fourth magnet 432 attracts the third magnet 431. When the sliding key 41 is in the fourth position, the fifth magnet 433 attracts the third magnet 431.

[0063] It can be understood that the fourth magnet 432, the third magnet 431 and the fifth magnet 433 are arranged in sequence along the sliding direction of the slider 22. When the sliding key 41 switches to the third position, under the magnetic attraction of the third magnet 431 and the fourth magnet 432, the sliding key 41 can remain in the third position, so that the slider 22 remains in the first position. When the sliding key 41 switches to the fourth position, under the magnetic attraction of the third magnet 431 and the fifth magnet 433, the sliding key 41 can remain in the fourth position, so that the slider 22 remains in the second position. In this embodiment, the magnetic attraction of the magnet is used to prevent the sliding key 41 from moving back and forth, thus ensuring the fixation of its position.

[0064] It should be noted that the limiting member 43 can also be in other structural forms, and the present application does not make specific limitations thereto. For example, the limiting member 43 includes two limiting grooves provided on the middle frame 1 and limiting beads provided on the sliding key 41, and the limiting beads are telescopically arranged on the sliding key 41. When the sliding key 41 is in the third position, the limiting beads are limited in one of the limiting grooves. When the sliding key 41 is in the fourth position, the limiting beads are limited in the other limiting groove. When the sliding key 41 is pushed by an external force, the limiting beads can be squeezed by the middle frame 1 and retracted, so as to realize the switching of the sliding key 41 between the third position and the fourth position.

[0065] As Figure 2 and Figure 3 shown, in some embodiments of the present application, a third installation groove 14 is provided on the second side surface 102 of the middle frame 1, and the second side surface 102 is adjacent to the first side surface 101. The installation hole 11 penetrates through the two groove walls of the third installation groove 14. The sliding groove 15 is communicated with the third installation groove 14. The key 21 is located on one side of the third installation groove 14 close to the first side surface 101, and the plunger 23 is located on the side of the third installation groove 14 away from the first side surface 101. The slider 22 is slidably arranged in the third installation groove 14.

[0066] It can be understood that the second side surface 102 is the front surface of the middle frame 1 corresponding to the mobile phone screen or the back surface corresponding to the mobile phone battery. The notch direction of the third installation groove 14 is perpendicular to the axial direction of the installation hole 11, and the third installation groove 14 extends along the sliding direction of the slider 22. Optionally, the sliding direction of the slider 22 is perpendicular to the axial direction of the installation hole 11.

[0067] Among them, the sliding key 41 passes through the sliding groove 15, a part of the sliding key 41 is located in the third installation groove 14 and is connected to the connecting rod 42, the fourth magnet 432 and the fifth magnet 433 are fixed in the third installation groove 14 and are respectively located on both sides of the sliding key 41. The through hole section 112 of the installation hole 11 includes a first through hole section and a second through hole section. The first through hole section connects the counterbore section 111 and the third installation groove 14, and the second through hole section connects the third installation groove 14 and the first installation groove 12. The ejector pin 212 is movably arranged in the first through hole section along the axial direction of the installation hole 11, and the plunger 23 is movably arranged in the second through hole section along the axial direction of the installation hole 11. The connecting rod 42 is received in the third installation groove 14 and can move in the third installation groove 14 along with the sliding key 41 and the slider 22.

[0068] As Figure 9As shown, in some embodiments of the present application, two limiting claws 422 are convexly provided on one end side of the connecting rod 42. The upper limit of the sliding direction of the slider 22 is located between the two limiting claws 422. It can be understood that the two limiting claws 422 are arranged on the connecting rod 42 along the sliding direction of the slider 22, and are located on the side of the connecting rod 42 away from the notch of the third mounting groove 14. In the axial direction of the mounting hole 11, the size of the limiting claw 422 is smaller than the size of the slider 22 to prevent the limiting claw 422 from having structural interference with the top column 212 when the button 21 is pressed.

[0069] like Figure 7 and Figure 9 As shown, in some embodiments of the present application, the other end side of the connecting rod 42 is convexly provided with an assembly column 421, the sliding key 41 is provided with an assembly hole 4121 for the assembly column 421, and the assembly column 421 is inserted into the assembly hole 4121. Specifically, the sliding key 41 includes a toggle portion 411 and a connecting portion 412 that are connected to each other. The slide groove 15 includes a sinking groove section 151 and a through groove section 152 that are connected to each other. The sinking groove section 151 is connected to the first side surface 101, and the through groove section 152 communicates the sinking groove section 151 and the third mounting groove 14. The toggle portion 411 is accommodated in the sinking groove section 151, and the connecting portion 412 is penetrated through the through groove section 152 and a part of it is located in the third mounting groove 14. The assembly hole 4121 is provided in the connecting portion 412, and the connecting rod 42 is connected to the sliding key 41 through the cooperation of the assembly column 421 and the assembly hole 4121.

[0070] It should be noted that the assembly column 421 can also be provided on the sliding key 41 , and correspondingly, the assembly hole 4121 is provided on the connecting rod 42 , so that the connecting rod 42 can also be connected to the sliding key 41 through the cooperation of the assembly column 421 and the assembly hole 4121 .

[0071] The number of the assembly posts 421 and the number of the assembly holes 4121 can both be two, and the two assembly posts 421 are respectively arranged on both sides of the connecting portion 412 in the sliding direction of the slider 22, so that the connection between the sliding key 41 and the connecting rod 42 is more stable.

[0072] Optionally, the assembly column 421 and the limiting claw 422 are located on the same side of the connecting rod 42, for example, both are located on the side of the connecting rod 42 away from the notch of the third mounting groove 14. When installing the slider 22 and the connecting rod 42, firstly set the slider 22 in the third mounting groove 14, and make the slider 22 abut between the button 21 and the plunger 23; then set the connecting rod 42 in the third mounting groove 14, and make the slider 22 between the two limiting claws 422, and at the same time, insert the assembly column 421 into the corresponding assembly hole 4121.

[0073] like Figure 2 and Figure 3As shown, the electronic device provided by some embodiments of the present application further includes a cover plate 6. The cover plate 6 is connected to the middle frame 1 and covers the connecting rod 42 and the slider 22. The cover plate 6 is used to limit the displacement of the connecting rod 42 and the slider 22 in the depth direction of the third installation groove 14. For example, the cover plate 6 is detachably connected to the middle frame 1 through fasteners such as screws, or for another example, the cover plate 6 is adhered to the middle frame 1 through an adhesive. When the connecting rod 42 is connected to the slider 22 and the sliding key 41 through two limiting claws 422 and the assembly post 421, the setting of the cover plate 6 can prevent the connecting rod 42 from detaching from the slider 22 and the sliding key 41.

[0074] As Figure 2 shown, in some embodiments of the present application, a limiting groove 141 is provided on the groove wall at one end of the third installation groove 14. One end of the cover plate 6 is inserted into the limiting groove 141, and the other end of the cover plate 6 is connected to the middle frame 1 through a fastener 7. In this way, the number of fasteners 7 used to connect the cover plate 6 and the middle frame 1 can be reduced, and the installation efficiency can be improved.

[0075] Figure 2 The limiting groove 141 shown in is provided on the groove wall at one end of the third installation groove 14 close to the sliding key 41. One end of the cover plate 6 is inserted into the limiting groove 141, and the other end is connected to the middle frame 1 through a screw. Of course, the limiting groove 141 can also be provided on the groove wall at one end of the third installation groove 14 close to the key 21.

[0076] Furthermore, multiple stepped surfaces are provided on the side of the cover plate 6 close to the connecting rod 42. When the connecting rod 42 is connected to the sliding key 41 through the assembly post 421, the connecting rod 42 and the sliding key 41 form a stepped structure. One stepped surface of the cover plate 6 is used to limit the displacement of the connecting rod 42 in the depth direction of the third installation groove 14, and the other stepped surface is used to limit the displacement of the sliding key 41 in the depth direction of the third installation groove 14, so as to form a good limit on the connecting rod 42 and the sliding key 41.

[0077] As Figure 11 and Figure 14 shown, in some embodiments of the present application, a first plane 2121 and a first inclined surface 2122 inclined away from the plunger 23 are provided on the side of the key 21 close to the plunger 23. A second plane 221 and a second inclined surface 222 inclined towards the plunger 23 are provided on the side of the slider 22 facing away from the plunger 23.

[0078] In the case where the slider 22 is in the first position, the second plane 221 abuts against the first plane 2121. In the case where the slider 22 is in the second position, the second inclined surface 222 abuts against the first inclined surface 2122.

[0079] It can be understood that the first plane 2121 is parallel to the second plane 221, and the first inclined plane 2122 is parallel to the second inclined plane 222. In this way, when the slider 22 is in the first position and the second position, both the button 21 and the slider 22 are in surface contact, and the slider 22 has a stable support for the button 21, avoiding the shaking of the button 21.

[0080] In some embodiments of the present application, the number of the button assemblies 2 is two, and the two button assemblies 2 are respectively arranged at both ends of the first side surface 101. For example, the first side surface 101 is a side surface in the length direction of the mobile phone middle frame. The two button assemblies 2 are respectively arranged at both ends in the length direction of the middle frame. When the user uses the mobile phone in landscape mode for playing games, the two buttons 21 can be respectively operated by both hands, improving the gaming experience. Correspondingly, the number of the transmission assemblies 4 is also two, and the two transmission assemblies 4 and the two button assemblies 2 are arranged in one-to-one correspondence.
