electronic devices

[0001] This application claims priority to Chinese patent application filed on October 18, 2024, with application number 202411464636.1 and entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0003] Electronic devices generally include mobile phones, tablets, computers, monitors, or in-vehicle computers. Physical buttons are an important component of electronic devices, allowing users to operate them conveniently. Users can control the power on / off of the device, adjust the volume, or perform functions such as taking photos, adjusting the brightness, or fingerprint recognition by pressing buttons.

[0004] Therefore, there is an urgent need for a design solution that can reduce or eliminate button wobble in directions other than the pressing direction without affecting button pressability, so as to improve the user experience of electronic devices. Summary of the Invention

[0005] This application provides an electronic device that can reduce or eliminate button wobble in directions other than the pressing direction without affecting button pressing, thereby improving the user experience of the electronic device.

[0006] This application provides an electronic device, comprising: a body; a button hole, the axial direction of which is a first direction; a button, mounted in the button hole, the surface of which faces the inside of the button hole being a mounting surface; and a limiting mechanism, including a first limiting member and a second limiting member, the first limiting member being disposed on the mounting surface, the second limiting member being disposed on the body and located in the button hole, the first limiting member moving along the first direction with the button; and the second limiting member being used to suppress the movement of the first limiting member and the button along the second direction; the first direction is the axial direction of the button hole, and the second direction intersects the first direction.

[0007] This application provides an electronic device with a limiting mechanism within a button hole. A first limiting member of the limiting mechanism is disposed on the mounting surface of the button, and a second limiting member is disposed within the button hole and corresponding to the first limiting member. The first limiting member can move along a first direction with the button, while the second limiting member is fixed to the device body and does not move. Through the interaction between the first and second limiting members, the second limiting member can suppress the movement of the first limiting member in a second direction, thus allowing the first limiting member to move only in the first direction. Since the first limiting member is connected to the button, the second limiting member can suppress the movement of the button in the second direction by suppressing the movement of the first limiting member in the second direction. Therefore, without affecting button pressing, the limiting mechanism can improve the problem of button wobbling caused by movement or offset in directions other than the first direction, improving the user's pressing experience and thus enhancing the overall user experience of the electronic device.

[0008] In addition, enabling the button to move along the axial direction of the button hole can prevent the button's outer wall from colliding with the inner wall of the button hole when the button's movement direction is inconsistent with the axial direction of the button hole, thus preventing the button from being pressed normally.

[0009] Based on the above scheme, this application also has the following improvements.

[0010] In one possible implementation, the second direction is perpendicular to the first direction.

[0011] By making the second direction perpendicular to the first direction, the wobble caused by the offset of the button in the radial direction perpendicular to the axis of the button hole can be reduced or eliminated. This allows the user to not feel the left and right wobble of the button relative to the button hole when using the button, thereby improving the user's button pressing experience and enhancing the user experience of electronic devices.

[0012] In one possible implementation, the second limiting member has a limiting hole with its opening facing the first limiting member and its axial direction extending along the first direction. The first limiting member is inserted into the limiting hole. The first limiting member moves relative to the inner wall of the limiting hole along the first direction. The outer wall of the first limiting member contacts the inner wall of the limiting hole. The limiting hole is used to restrict the displacement of the first limiting member along the second direction.

[0013] In this way, by opening a limiting hole on the second limiting member and extending the first limiting member into the limiting hole, the first limiting member contacts the inner wall of the limiting hole. When the first limiting member moves relative to the limiting hole in the first direction, the outer wall of the first limiting member and the inner wall of the limiting hole generate sliding friction resistance through contact. While ensuring that the button can be pressed normally, the inner wall circumferentially set in the limiting hole can also suppress the movement or offset of the first limiting member and the button in the second direction, thereby suppressing the shaking of the button and improving the user experience of the button and electronic device.

[0014] In one possible implementation, when the button is not subjected to external force, the inner wall of the limiting hole serves to prevent the first limiting member and the button from moving toward the inside of the button hole.

[0015] In this way, when the button is not subjected to external force, such as when the user is not pressing the button and the button is in a state where the contact point on the device is not triggered, the frictional resistance between the inner wall of the limiting hole and the first limiting member will keep the first limiting member and the inner wall of the limiting hole relatively stationary. The first limiting member will not move in the first direction, thereby preventing the first limiting member and the button from moving towards the inside of the button hole. This will eliminate the play between the button and the button hole in the first direction, further improve the user experience when pressing the button, and improve the user experience of the electronic device.

[0016] In one possible implementation, the first limiting member includes: a limiting rod disposed on the mounting surface of the first limiting member and extending along the first direction into the limiting hole, wherein there is a gap between the outer sidewall of the limiting rod and the inner sidewall of the limiting hole; an elastic member disposed within the gap, wherein the outer sidewall of the limiting rod abuts against the inner sidewall of the limiting hole via the elastic member; and the limiting rod moves relative to the limiting hole along the first direction.

[0017] In this way, the first limiting member includes a limiting rod and an elastic element. One end of the limiting rod is fixedly connected to the mounting surface of the button, and the other end extends into the limiting hole. The elastic element fills the gap between the inner wall of the limiting hole and the outer wall of the limiting rod, so that the limiting rod abuts against the inner wall of the limiting hole through the elastic element. Since the elastic element fills the gap between the limiting rod and the limiting hole, it can suppress the displacement or offset of the limiting rod in the radial direction of the limiting hole, thereby preventing the limiting rod and the button from shaking in the radial direction of the limiting hole and ensuring that the limiting rod and the button can move in the first direction, thus improving the user's experience of using the electronic device.

[0018] In one possible implementation, the elastic element is disposed in at least a portion of the outer peripheral surface of the limiting rod.

[0019] In this way, by setting the elastic element on at least a portion of the outer peripheral surface of the limiting rod, the radial swaying of the limiting rod along the limiting hole can be suppressed, the usable area of ​​the elastic element can be reduced, the material cost of the elastic element can be reduced, and thus the manufacturing cost of electronic devices can be reduced.

[0020] In one possible implementation, the elastic element is an annular element; the annular element is disposed around the outer periphery of the limiting element, the limiting rod contacts the inner wall of the limiting hole through the annular element, and the limiting rod drives the annular element to move along the first direction.

[0021] In this way, by setting the elastic element as a ring and sleeved on the outer periphery of the limiting rod, the elastic element can contact the inner wall of the limiting hole in a 360-degree circumferential direction around the limiting rod. This allows the limiting hole to provide 360-degree all-round elastic support and limitation for the limiting rod in a circumferential direction through the ring element, preventing the limiting rod and the button from shifting in the radial direction of the limiting hole. This improves the uniformity of the elastic element's support and limitation of the button limiting rod, ensures the stability of the button during pressing, further reduces the amplitude of button wobble, and improves the user experience of electronic devices.

[0022] In one possible implementation, the outer wall of the limiting rod has a mounting groove; the opening of the mounting groove faces the inner wall of the limiting hole, and the elastic element is disposed within the mounting groove.

[0023] In this way, by setting an installation groove on the limiting rod and placing the elastic element in the installation groove, the connection stability of the elastic element on the limiting rod can be improved, and the probability of relative sliding between the elastic element and the limiting rod during the movement of the elastic element along the first direction with the limiting rod can be reduced.

[0024] In addition, by setting a mounting groove on the limiting rod and placing the elastic element in the mounting groove, it is easier to position and install the elastic element on the limiting rod, thereby helping to improve the assembly efficiency of electronic devices.

[0025] In one possible implementation, the outer wall of the limiting rod has an annular groove arranged circumferentially, and the annular element is disposed within the annular groove.

[0026] In this way, by setting an annular groove on the limiting rod that matches the annular component and placing the annular component in the annular groove, the installation stability of the annular component on the limiting rod can be improved, and relative sliding between the annular component and the limiting rod can be avoided during button pressing.

[0027] In one possible implementation, the first limiting member is disposed on the mounting surface of the button in a region near the center.

[0028] In this way, by placing the first limiting member in the area near the center of the mounting surface, the force distribution on each area of ​​the button can be made more even, which helps to reduce the tilting or shaking of the button during the pressing process, thereby providing a more stable and consistent button pressing experience.

[0029] In one possible implementation, a receiving groove is provided on the mounting surface of the button, and the receiving groove is disposed on the outer periphery of the first limiting member; when the button moves along the first direction, a portion of the second limiting member extends into the receiving groove.

[0030] In this way, by opening a receiving groove on the mounting surface of the button, the thickness of the button in the first direction is fully utilized so that part of the second limiting member can extend into the receiving groove in the thickness direction of the button. This increases the space between the button and the button hole in the first direction, making it easier to accommodate a longer second limiting member. This allows the limiting rod to extend more into the limiting hole, improving the limiting effect on the limiting rod and increasing the space utilization rate on the button.

[0031] In one possible implementation, the limiting mechanism includes a plurality of first limiting members and a plurality of second limiting members, each of the second limiting members corresponding to one of the first limiting members; the plurality of first limiting members are arranged at intervals on the surface of the button facing the button hole.

[0032] In this way, by setting multiple first limiting elements and multiple second limiting elements, with each first limiting element corresponding to one second limiting element, and with the multiple first limiting elements arranged at intervals, the uniformity of force on the button can be increased, thereby reducing the shaking amplitude of various areas on the button and making the movement distance of various areas on the button along the first direction as consistent as possible, thus improving the user's experience of using electronic devices.

[0033] In one possible implementation, the elastic element is a rubber element or a silicone element.

[0034] Because rubber and silicone have good elastic deformation capacity, as well as good wear resistance and corrosion resistance, rubber and silicone parts have good elastic deformation capacity, as well as good wear resistance and corrosion resistance. Therefore, while ensuring the elasticity of the elastic parts, the service life of the elastic parts can be increased, the maintenance and replacement costs of the elastic parts can be reduced, and the manufacturing and maintenance costs of electronic equipment can be reduced.

[0035] In one possible implementation, the button further includes a pressing part; the pressing part is disposed on the mounting surface of the button, and the pressing part and the first limiting member are arranged at intervals on the mounting surface; the pressing part is used to trigger a contact on the device body when the button is pressed.

[0036] In this way, since the first limiting member and the second limiting member are set in a corresponding manner, and the second limiting member and the pressing part are offset from each other in the first direction, the first limiting member, under the action of the second limiting member, enables the limiting mechanism to not only ensure the suppression of button shaking, but also to avoid the limiting mechanism from obstructing the process of the pressing part triggering the contact point on the device body, thereby improving the practicality of the electronic device.

[0037] In one possible implementation, the pressing part has two parts, which are spaced apart, and the limiting mechanism is disposed between the two pressing parts.

[0038] In this way, when there are two pressing parts, by setting the limiting mechanism between the two pressing parts, the limiting mechanism can suppress the wobble of the button at the two pressing parts almost equally, thereby making the limiting mechanism suppress the wobble of the entire button more uniform.

[0039] In one possible implementation, the electronic device further includes a latching member disposed on the side of the button near the button hole; the inner wall of the button hole has a slot, and a portion of the latching member extends into the slot; the slot has a first slot wall and a second slot wall opposite to each other in a first direction, the first slot wall being closer to the opening of the button hole than the second slot wall, and the latching member abutting against the first slot wall when the button is not subjected to external force.

[0040] By setting a snap-fit ​​component and a corresponding slot on the inner wall of the button hole, the snap-fit ​​component moves along the first direction with the button, and the slot can limit the displacement of the button in the first direction by limiting the snap-fit ​​component, and can prevent the button from coming out of the button hole, thereby improving the stability of the fit between the button and the button hole and improving the practicality of the electronic device.

[0041] In one possible implementation, along the first direction, the distance from the second limiting member to the plane where the key hole is located is a first distance; the distance from the first groove wall of the card slot to the plane where the key hole is located is a second distance; the first distance is less than the second distance.

[0042] In this way, by making the first distance smaller than the second distance, the distance from the second limiting member to the plane where the key hole is located can be made smaller than the distance from the first groove wall to the plane where the key hole is located. This avoids the problem that the first limiting member will come out of the limiting hole of the second limiting member due to the excessive travel of the key, and further causes the limiting mechanism to fail to limit the keycap's shaking.

[0043] In one possible implementation, the body includes a middle frame, on which the button hole is provided, and the second limiting member of the limiting mechanism is disposed in the area corresponding to the inside of the middle frame and the button hole.

[0044] In this way, the device body includes a mid-frame, and the button holes are located on the mid-frame. When the buttons and limiting mechanisms are placed within the button holes, from the perspective of the device body, the buttons can be located on the side of the device body. Therefore, by placing the buttons on the side of the device body, it is easier for users to press the buttons, reducing the space occupied by the buttons on the device body and improving the user experience of the electronic device.

Detailed Implementation

[0052] This application provides an electronic device, which includes, but is not limited to, mobile phones (e.g., candybar phones or foldable phones), tablet computers, laptops, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, internet TVs, televisions, in-vehicle devices, netbooks, POS machines, personal digital assistants (PDAs), wearable devices (e.g., smartwatches, smart wristbands, virtual reality devices, and other mobile or fixed terminals with display devices).

[0053] In this embodiment of the application, a mobile phone is used as an example of the above-mentioned electronic device. The mobile phone can at least access the Internet, browse web pages, play multimedia, and also conduct remote network video communication and calls with other users through the camera device in the IPTV.

[0054] Figure 1 is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0055] Referring to Figure 1, the electronic device may include a body 100 and buttons 200. Buttons 200 are physical buttons, allowing users to operate contacts 151 on the body 100 by pressing them. The body 100 may include a circuit board 150, which has contacts 151. For example, contacts 151 on the circuit board 150 can be used to control the electronic device to turn on or off, adjust the volume, or control the camera function to take pictures. Therefore, the user experience of buttons 200 directly affects the user's experience with the electronic device. The body 100 may include a screen assembly 130 and a mid-frame 120. The screen assembly 130 is located within the mid-frame 120, which is positioned at the outer edge of the screen assembly 130. The mid-frame 120 supports the screen assembly 130, reducing the likelihood of deformation or breakage and thus extending the lifespan of the electronic device.

[0056] In some embodiments, the button hole 110 can be formed on the mid-frame 120 of the body 100, so that the button 200 can be set on the mid-frame 120 of the body 100 and located on the side of the body 100. By setting the button 200 on the side of the body 100, the button 200 can be avoided from occupying space on the screen assembly 130, thereby improving the space utilization and aesthetics of the screen assembly 130. Furthermore, by installing the button 200 on the side of the body 100, it is easier for the user to operate the button 200, thus improving the user's experience of using the electronic device.

[0057] Therefore, there is an urgent need for a design solution that can reduce or eliminate button wobble in directions other than the pressing direction without affecting button pressability, so as to improve the user experience of electronic devices.

[0058] Referring to Figures 2 and 3, the main reason for this problem is that, in the relevant technology, there is a gap 140 between the outer periphery of a portion of the button 200 located within the button hole 110 and the inner wall of the button hole 110. When the button 200 moves within the button hole 110, the gap 140 causes the button 200 to wobble, thus affecting the user's experience of using the electronic device. Furthermore, there may be a certain distance between the button 200 and the contact point 151, which will cause a certain amount of play in the direction of the button 200's pressing stroke. This will cause the button 200 to wobble in the stroke direction even without external force, also affecting the user's experience of using the button 200 and the electronic device.

[0059] Referring to Figures 2 and 3, to address the aforementioned technical problems, this application provides an electronic device. A limiting mechanism 300 is provided within a button hole 110. A first limiting member 310 of the limiting mechanism 300 is disposed on the mounting surface 210 of the button 200. A second limiting member 320 of the limiting mechanism 300 is disposed within the button hole 110 and corresponds to the first limiting member 310. The first limiting member 310 can move along the first direction with the button 200, while the second limiting member 320 is fixed to the body 100 and does not move. Through the interaction between the first limiting member 310 and the second limiting member 320, the second limiting member 320 can suppress the movement of the first limiting member 310 in the second direction. Thus, the first limiting member 310 can only move along the first direction. Since the first limiting member 310 is connected to the button 200, the second limiting member 320 can suppress the movement of the button 200 in the second direction by suppressing the movement of the first limiting member 310 in the second direction. Therefore, without affecting the pressing of button 200, the problem of button 200 shaking caused by movement or offset in directions other than the first direction can be improved by setting a limit mechanism 300, thereby improving the user's pressing experience when using button 200 and thus improving the user experience of electronic devices.

[0060] In addition, enabling the button 200 to move along the axial direction of the button hole 110 can prevent the button 200 from moving in a direction inconsistent with the axial direction of the button hole 110, which would cause the outer wall of the button 200 to collide with the inner wall of the button hole 110 and prevent the button 200 from being pressed normally.

[0061] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0062] Referring to Figures 1 to 3, this application provides an electronic device, which may include a body 100, buttons 200, and a limiting mechanism 300. The body 100 may include a middle frame 120, on which a button hole 110 is provided. The second limiting member 320 of the limiting mechanism 300 is disposed in the area corresponding to the inside of the middle frame 120 and the button hole 110.

[0063] Thus, the body 100 may include a mid-frame 120, with a button hole 110 formed on the mid-frame 120. When the button 200 and the limiting mechanism 300 are disposed within the button hole 110, from the perspective of the body 100, the button 200 can be located on the side of the body 100. Therefore, by placing the button 200 on the side of the body 100, it is easier for the user to press the button 200, reducing the space occupied by the button 200 on the body 100 and improving the user's experience of using the electronic device.

[0064] The axial direction of the key hole 110 is the first direction (Y direction in Figure 3). The key 200 is installed in the key hole 110. The surface of the key 200 facing the inside of the key hole 110 is the mounting surface 210. When the key 200 is installed in the key hole 110, the key 200 can move along the axial direction of the key hole 110.

[0065] The limiting mechanism 300 may include a first limiting member 310 and a second limiting member 320. The first limiting member 310 is disposed on the mounting surface 210 to fix the first limiting member 310 and the button 200 together, thus facilitating the movement of the button 200 and the first limiting member 310 together along a first direction. The second limiting member 320 is disposed on the body 100 and located within the button hole 110. For example, both the second limiting member 320 and the button hole 110 can be disposed on the middle frame 120 of the body 100. For example, after the button hole 110 is formed on the middle frame 120, the second limiting member 320 can be further disposed within the button hole 110 to connect the second limiting member 320 with the middle frame 120.

[0066] Thus, the body 100 can include a mid-frame 120, on which mounting holes are formed. When the button 200 and the elastic element 312 are disposed within the mounting holes, from the perspective of the body 100, the button 200 can be located on the side of the body 100. Therefore, by placing the button 200 on the side of the body 100, it is easier for the user to press the button 200, reducing the space occupied by the button 200 on the body 100 and improving the user's experience with the electronic device.

[0067] The first limiting member 310 and the second limiting member 320 can slide relative to each other. The second limiting member 320 is fixedly disposed on the body 100 at a position corresponding to the inside of the button hole 110 and does not move. The first limiting member 310 can move relative to the second limiting member 320 along a first direction, and the second limiting member 320 has a suppressive effect on the movement direction of the first limiting member 310. For example, the second limiting member 320 can be used to suppress the movement or offset of the first limiting member 310 along a second direction (X direction in Figure 3), wherein the second direction intersects with the first direction. In this way, since the first limiting member 310 and the button 200 can move together, the second limiting member 320 can restrict the movement or offset of the button 200 along the second direction with the first limiting member 310 by restricting the movement of the first limiting member 310.

[0068] This application provides an electronic device. By providing a limiting mechanism 300 in the keyhole 110, a first limiting member 310 of the limiting mechanism 300 is disposed on the mounting surface 210 of the key 200, and a second limiting member 320 of the limiting mechanism 300 is disposed in the keyhole 110 and corresponding to the first limiting member 310. The first limiting member 310 can move along the first direction with the key 200, while the second limiting member 320 is fixed to the body 100 and does not move. Through the interaction between the first limiting member 310 and the second limiting member 320, the second limiting member 320 can suppress the movement of the first limiting member 310 in the second direction, thereby enabling the first limiting member 310 to move only in the first direction. Since the first limiting member 310 is connected to the key 200, the second limiting member 320 can suppress the movement of the key 200 in the second direction by suppressing the movement of the first limiting member 310 in the second direction. Therefore, without affecting the pressing of button 200, the problem of button 200 shaking caused by movement or offset in directions other than the first direction can be improved by setting a limit mechanism 300, thereby improving the user's pressing experience when using button 200 and thus improving the user experience of electronic devices.

[0069] In addition, enabling the button 200 to move along the axial direction of the button hole 110 can prevent the button 200 from moving in a direction inconsistent with the axial direction of the button hole 110, which would cause the outer wall of the button 200 to collide with the inner wall of the button hole 110 and prevent the button 200 from being pressed normally.

[0070] Referring to Figures 1 and 2, in some embodiments, the body 100 may further include a screen assembly 130, and the mid-frame 120 can be used to fix the screen assembly 130, reducing the probability of the screen assembly 130 breaking or deforming, improving the strength of the body 100, and thus enhancing the strength of the electronic device. If the mid-frame 120 has mounting holes, the mounting holes are located on the side of the body 100, and the button 200 can be installed in the mounting holes on the side of the body 100.

[0071] Referring to Figures 3 and 4, in some embodiments, it can be understood that the second direction intersecting the first direction (X direction in Figure 3) can be any direction other than parallel to the first direction. For example, the second direction can be a direction perpendicular to the first direction, or the angle between the second direction and the first direction can be any angle within the range of greater than 0 degrees and less than 90 degrees.

[0072] In a specific implementation, the second direction is perpendicular to the first direction. If the first direction is the axial direction of the button hole 110, when the second direction is perpendicular to the first direction, the second direction has multiple different directions, and these multiple different directions are coplanar. That is, the surface where the second direction is located can be perpendicular to the first direction, and other directions coplanar with the second direction can also be perpendicular to the first direction.

[0073] By making the second direction perpendicular to the first direction, the wobble caused by the offset of the button 200 in the radial direction perpendicular to the axis of the button hole 110 can be reduced or eliminated. This allows the user to not feel the left and right wobble of the button 200 relative to the button hole 110 when using the button 200, thereby improving the user's pressing experience of the button 200 and enhancing the user experience of the electronic device.

[0074] Referring to Figure 3, in some embodiments, the second limiting member 320 has a limiting hole 321, the opening of which faces the first limiting member 310. The axial direction of the limiting hole 321 extends along a first direction (X direction in Figure 3). The limiting hole 321 can be coaxially arranged with the button hole 110, or the axial direction of the limiting hole 321 can be parallel to the axial direction of the button hole 110. The first limiting member 310 is inserted into the limiting hole 321 and moves relative to the inner wall of the limiting hole 321 along the first direction.

[0075] The outer sidewall of the first limiting member 310 contacts the inner sidewall of the limiting hole 321, so that frictional resistance is generated when the first limiting member 310 moves relative to the sidewall of the limiting hole 321. The limiting hole 321 is used to limit the displacement of the first limiting member 310 in the second direction.

[0076] In this way, by opening a limiting hole 321 on the second limiting member 320 and extending the first limiting member 310 into the limiting hole 321, the first limiting member 310 contacts the inner wall of the limiting hole 321. When the first limiting member 310 moves relative to the limiting hole 321 in the first direction, the outer wall of the first limiting member 310 and the inner wall of the limiting hole 321 generate sliding friction resistance through contact. While ensuring that the button 200 can be pressed normally, since the outer wall of the first limiting member 310 contacts the inner wall of the limiting hole 321, there is no gap between the outer wall of the first limiting member 310 and the inner wall of the limiting hole 321. Thus, the inner wall circumferentially set in the limiting hole 321 can suppress the movement or offset of the first limiting member 310 and the button 200 in the second direction, and make the first limiting member 310 only able to move along the axial direction of the limiting hole 321, thereby suppressing the shaking of the button 200 and improving the user experience of the button 200 and the electronic device.

[0077] Furthermore, since the outer sidewall of the first limiting member 310 and the inner sidewall of the limiting hole 321 will generate sliding friction resistance due to contact, this can prevent the button 200 from shaking in the first direction when there is a gap between the button 200 and the contact 151. This allows the button 200 to be fixed in a certain position in the first direction by friction resistance when it is not subjected to external force.

[0078] Referring to Figure 3, in some other embodiments, the limiting hole 321 can also be formed on the first limiting member 310, with the opening of the limiting hole 321 facing the second limiting member 320. The second limiting member 320 is inserted into the limiting hole 321 of the first limiting member 310, and the outer side wall of the second limiting member 320 contacts the inner side wall of the limiting hole 321 on the first limiting member 310. Therefore, the movement of the first limiting member 310 along the axial direction of the limiting hole 321 can be restricted, thereby also suppressing the shaking of the button 200 in the second direction through the limiting mechanism 300.

[0079] Referring to Figure 3, in some embodiments, when the button 200 is not subjected to external force, the inner wall of the limiting hole 321 is used to prevent the first limiting member 310 and the button 200 from moving toward the button hole 110.

[0080] In this way, when the button 200 is not subjected to external force, for example, when the user does not press the button 200 and the button 200 is in a state where the contact 151 on the body 100 is not triggered, the frictional resistance between the inner wall of the limiting hole 321 and the first limiting member 310 makes the first limiting member 310 and the inner wall of the limiting hole 321 relatively stationary. The first limiting member 310 does not move in the first direction under the action of frictional resistance, so as to prevent the first limiting member 310 and the button 200 from moving towards the button hole 110. This can eliminate the play in the first direction between the button 200 and the button hole 110, further improve the user experience when pressing the button 200, and improve the user experience of the electronic device.

[0081] Referring to Figures 3, 4 and 5, in some embodiments, the first limiting member 310 may include a limiting rod 311 and an elastic member 312.

[0082] A limiting rod 311 is disposed on the mounting surface 210 of the first limiting member 310 and extends along the first direction (Y direction in Figure 3) into the limiting hole 321. There is a gap between the outer sidewall of the limiting rod 311 and the inner sidewall of the limiting hole 321. An elastic member 312 is disposed within the gap, and the outer sidewall of the limiting rod 311 abuts against the inner sidewall of the limiting hole 321 through the elastic member 312. The limiting rod 311 can move relative to the limiting hole 321 along the first direction.

[0083] Thus, the first limiting member 310 may include a limiting rod 311 and an elastic member 312. One end of the limiting rod 311 is fixedly connected to the mounting surface 210 of the button 200, and the other end extends into the limiting hole 321. The elastic member 312 fills the gap between the inner wall of the limiting hole 321 and the outer wall of the limiting rod 311, so that the limiting rod 311 abuts against the inner wall of the limiting hole 321 through the elastic member 312. Since the elastic member 312 fills the gap between the limiting rod 311 and the limiting hole 321, the displacement or offset of the limiting rod 311 in the radial direction of the limiting hole 321 can be suppressed, thereby preventing the limiting rod 311 and the button 200 from shaking in the radial direction of the limiting hole 321, and ensuring that the limiting rod 311 and the button 200 can move in the first direction, improving the user's experience of using the electronic device.

[0084] Furthermore, by having the limiting rod 311 and the inner wall of the limiting hole 321 contact each other through the elastic member 312, direct hard contact between the limiting rod 311 and the inner wall of the limiting hole 321 can be avoided. This prevents wear on the outer wall of the limiting rod 311 and the inner wall of the limiting hole 321 due to sliding friction, thereby improving the durability of the limiting rod 311 and the second limiting member 320, enhancing the durability of the limiting mechanism 300, and reducing the maintenance costs of electronic equipment.

[0085] In some embodiments, the elastic element 312 can be disposed on the outer side wall of the limiting rod 311. The elastic element 312 can be assembled with the limiting rod 311 on the button 200 first, and then the combined structure of the button 200, the limiting rod 311 and the elastic element 312 can be installed in the button hole 110, and the limiting rod 311 and the elastic element 312 can be installed in the limiting hole 321 of the second limiting element 320.

[0086] If the elastic element 312 is disposed on the outer wall of the limiting rod 311, when the limiting rod 311 moves along the first direction with the button 200, the elastic element 312 can move together with the limiting rod 311 relative to the inner wall of the limiting hole 321. At this time, relative sliding will occur between the elastic element 312 and the inner wall of the limiting hole 321, which can improve the installation stability of the elastic element 312, reduce the probability of relative sliding between the elastic element 312 and the limiting rod 311, and avoid the problem of the elastic element 312 detaching from the limiting rod 311. The sliding friction resistance between the elastic element 312 and the limiting hole 321 should not be too large, so as to avoid the problem that the limiting rod 311 and the elastic element 312 cannot move within the limiting hole 321.

[0087] In practice, the elastic element 312 can be bonded to the outer wall of the limiting rod 311 by adhesive. This can improve the connection stability between the elastic element 312 and the limiting rod 311, and simplify the assembly process of the elastic element 312 and the limiting rod 311, thereby improving the assembly efficiency of electronic devices.

[0088] In other embodiments, the elastic member 312 can also be disposed on the inner sidewall of the limiting hole 321, so that the surface of the elastic member 312 facing away from the inner sidewall of the limiting hole 321 contacts the outer sidewall of the limiting rod 311. When the limiting rod 311 moves within the limiting hole 321, the limiting rod 311 can move relative to the limiting hole 321 and the elastic member 312 along a first direction. The elastic member 312 can be directly injection molded onto the limiting rod 311, which can reduce the assembly time of the second limiting member 320 and the elastic member 312, thereby improving the assembly efficiency of the electronic device.

[0089] If the elastic element 312 can be provided on the inner wall of the limiting hole 321, the elastic element 312 can be bonded to the inner wall of the limiting hole 321 by adhesive, or the elastic element 312 can be fixed in the positioning groove by providing a positioning groove on the inner wall of the limiting hole 321, thereby reducing the probability of relative sliding of the elastic element 312 and improving the installation stability of the elastic element 312.

[0090] Referring to FIG3, in some embodiments, the elastic element 312 is disposed on at least a portion of the outer peripheral surface of the limiting rod 311. For example, the elastic element 312 may be disposed on the entire outer surface of the limiting rod 311, or on a portion of the outer surface of the limiting rod 311.

[0091] There may be multiple elastic elements 312, which can be spaced apart and evenly arranged on the outer side wall of the limiting rod 311 along the circumference of the limiting rod 311, or multiple elastic elements 312 can be spaced apart and evenly arranged on the inner side wall of the limiting hole 321 along the circumference of the limiting hole 321.

[0092] In this way, by setting the elastic element 312 on at least a portion of the outer peripheral surface of the limiting rod 311, the radial swaying of the limiting rod 311 along the limiting hole 321 can be suppressed, thereby reducing the usable area of ​​the elastic element 312, reducing the material cost of the elastic element 312, and thus reducing the manufacturing cost of electronic devices.

[0093] Referring to Figures 3 to 5, in some embodiments, the elastic member 312 can be an annular member, which is arranged around the outer periphery of the limiting member. The limiting rod 311 contacts the inner wall of the limiting hole 321 through the annular member, and the limiting rod 311 drives the annular member to move along the first direction (X direction in Figure 3).

[0094] In some embodiments, along the first direction, the annular member can completely cover the outer wall of the limiting rod 311, which can increase the contact area between the annular member and the limiting rod 311 and improve the connection stability between the annular member and the limiting rod 311.

[0095] In this way, by setting the elastic element 312 as a ring and sleeved on the outer periphery of the limiting rod 311, the elastic element 312 can contact the inner wall of the limiting hole 321 in a 360-degree circumferential direction around the limiting rod 311. This allows the limiting hole 321 to provide 360-degree all-round elastic support and limitation for the limiting rod 311 in a circumferential direction through the ring, avoiding the deviation of the limiting rod 311 and the button 200 in the radial direction of the limiting hole 321. This improves the uniformity of the support and limitation of the elastic element 312 for the limiting rod 311 of the button 200, ensures the stability of the button 200 during the pressing process, further reduces the amplitude of the button 200's shaking, and improves the user's experience of using the electronic device.

[0096] Referring to Figure 5, in some embodiments, the outer wall of the limiting rod 311 has a mounting groove 3111. The opening of the mounting groove 3111 faces the inner wall of the limiting hole 321, and the elastic element 312 is disposed in the mounting groove 3111.

[0097] In this way, by setting the mounting groove 3111 on the limiting rod 311 and placing the elastic element 312 in the mounting groove 3111, the connection stability of the elastic element 312 on the limiting rod 311 can be improved, and the probability of relative sliding between the elastic element 312 and the limiting rod 311 can be reduced during the process of the elastic element 312 moving along the first direction (X direction in Figure 5) with the limiting rod 311.

[0098] In addition, by providing a mounting groove 3111 on the limiting rod 311 and placing the elastic element 312 in the mounting groove 3111, it is possible to facilitate the positioning and installation of the elastic element 312 on the limiting rod 311, thereby helping to improve the assembly efficiency of electronic devices.

[0099] In some embodiments, if there are multiple elastic elements 312, and the multiple elastic elements 312 are arranged at intervals along the circumferential direction of the outer side wall of the limiting rod 311, then there may be multiple mounting grooves 3111. The mounting grooves 3111 and the elastic elements 312 can be arranged in a one-to-one correspondence. The multiple mounting grooves 3111 are arranged at intervals along the outer side wall of the limiting rod 311, and each mounting groove 3111 can be provided with one elastic element 312.

[0100] Referring to Figure 5, in some embodiments, if the elastic element 312 is an annular element, the outer wall of the limiting rod 311 has an annular groove arranged circumferentially, that is, the shape of the mounting groove 3111 can be annular, and the annular element is disposed in the annular groove.

[0101] In some embodiments, there may be multiple annular members, which are spaced apart along the axial direction of the limiting rod 311. This increases the contact area between the elastic member 312 and the inner wall of the limiting hole 321, thereby increasing the limiting effect of the limiting hole 321 on the radial displacement of the limiting rod 311 through the elastic member 312.

[0102] In this way, by setting an annular groove on the limiting rod 311 that is compatible with the annular part and placing the annular part in the annular groove, the installation stability of the annular part on the limiting rod 311 can be improved, and relative sliding between the annular part and the limiting rod 311 can be avoided during the pressing of the button 200.

[0103] Furthermore, an annular groove is provided on the limiting rod 311, which enables the installation and positioning of the annular part on the limiting rod 311, making it convenient to install the annular part on the limiting rod 311.

[0104] Referring to Figure 3, in some embodiments, the thickness of the elastic member 312 can be greater than the width of the gap, so that the outer wall of the limiting rod 311 can abut against the inner wall of the limiting hole 321 through the elastic member 312.

[0105] In this way, by making the thickness of the elastic element 312 greater than the width of the gap, the elastic element 312 is interference-fitted with the gap in the width direction of the gap. This allows the elastic element 312 to completely fill the gap in the width direction of the gap through elastic deformation, so that the limiting rod 311 directly abuts against the inner wall of the button hole 110 through the elastic element 312. This further reduces the probability of the button 200 shaking and further improves the user's experience of using the electronic device.

[0106] Furthermore, since the elastic element 312 can undergo elastic deformation, during the movement of the button 200, the elastic element 312 can also move along the axial direction of the button hole 110 with the limiting rod 311 on the button 200 through elastic deformation, so as to reduce the resistance of the elastic element 312 to the button 200 during the pressing process.

[0107] Referring to Figure 3, in some embodiments, the first limiting member 310 is disposed on the mounting surface 210 of the button 200 near the center. If the button 200 is elongated, such that the mounting surface 210 of the button 200 can also be elongated, then the first limiting member 310 can be disposed at the center of the mounting surface 210 in the length direction. If the mounting surface 210 of the button 200 is circular, then the first limiting member 310 can be disposed at the center of the mounting surface 210.

[0108] In this way, by setting the first limiting member 310 in the area near the center of the mounting surface 210, the force distribution in each area of ​​the button 200 can be made more even, which helps to reduce the tilting or shaking of the button 200 during the pressing process, thereby providing a more stable and consistent button 200 pressing experience.

[0109] Referring to Figures 3 to 5, in some embodiments, a receiving groove 220 is provided on the mounting surface 210 of the button 200, and the receiving groove 220 is disposed on the outer periphery of the first limiting member 310. When the button 200 moves along the first direction (X direction in Figure 3), a portion of the second limiting member 320 extends into the receiving groove 220.

[0110] In this way, by opening a receiving groove 220 on the mounting surface 210 of the button 200, the thickness of the button 200 in the first direction is fully utilized, so that part of the second limiting member 320 can extend into the receiving groove 220 in the thickness direction of the button 200. This increases the space between the button 200 and the button hole 110 in the first direction, making it easier to accommodate a longer second limiting member 320. This allows the limiting rod 311 to extend more into the limiting hole 321, improving the limiting effect on the limiting rod 311 and increasing the space utilization rate on the button 200.

[0111] Referring to Figure 3, in some embodiments, the limiting mechanism 300 may include a plurality of first limiting members 310 and a plurality of second limiting members 320, each second limiting member 320 corresponding to one first limiting member 310. The plurality of first limiting members 310 are arranged at intervals on the surface of the button 200 facing the button hole 110. In an exemplary embodiment, the limiting mechanism 300 may include two first limiting members 310 and two second limiting members 320, each first limiting member 310 corresponding to one second limiting member 320. The two first limiting members 310 can be evenly and at intervals arranged on the mounting surface 210 of the button 200, which can improve the uniformity of the distribution of the first limiting members 310 on the mounting surface 210 and facilitate the improvement of the uniformity of the force on the button 200.

[0112] In this way, by setting multiple first limiting members 310 and multiple second limiting members 320, and making each first limiting member 310 correspond to one second limiting member 320, and arranging the multiple first limiting members 310 at intervals, the uniformity of force on the button 200 can be increased, thereby reducing the shaking amplitude of each area on the button 200, making the movement distance of each area on the button 200 along the first direction as consistent as possible, and improving the user's experience of using the electronic device.

[0113] Referring to Figures 4 and 5, in some embodiments, the elastic element 312 is a rubber element or a silicone element.

[0114] In some embodiments, if the elastic element 312 is an annular element, the elastic element 312 may be an annular rubber element or an annular silicone element.

[0115] Thus, because rubber and silicone have good elastic deformation ability, as well as good wear resistance and corrosion resistance, rubber and silicone parts have good elastic deformation ability, as well as good wear resistance and corrosion resistance. Therefore, while ensuring the elasticity of the elastic part 312, the service life of the elastic part 312 can be improved, the maintenance and replacement cost of the elastic part 312 can be reduced, and the manufacturing and maintenance cost of electronic equipment can be reduced.

[0116] In practical implementation, if the elastic element 312 is a rubber element, the rubber element can be bonded to the outer wall of the limiting rod 311 by adhesive bonding. This can improve the assembly speed of the elastic element 312 and the limiting rod 311 and reduce the manufacturing cost of electronic devices.

[0117] In other embodiments, the rubber component can also be injection molded onto the outer wall of the limiting rod 311, which can improve the connection stability between the rubber component and the limiting rod 311, simplify the assembly steps between the limiting rod 311 and the elastic component 312, and improve the assembly efficiency of the electronic device.

[0118] Referring to Figures 4 to 6, in some embodiments, the button 200 may further include a pressing part 230, which is disposed on the mounting surface 210 of the button 200. The pressing part 230 and the first limiting member 310 are arranged at intervals on the mounting surface 210. The pressing part 230 is used to trigger the contact point 151 on the body 100 when pressed.

[0119] In this way, since the first limiting member 310 and the second limiting member 320 are correspondingly set, and the second limiting member 320 and the pressing part 230 are offset from each other in the first direction (X direction in Figure 6), the first limiting member 310, under the action of the second limiting member 320, enables the limiting mechanism 300 to not only suppress the shaking of the button 200, but also to avoid the limiting mechanism 300 from obstructing the process of the pressing part 230 triggering the contact 151 on the body 100, thereby improving the practicality of the electronic device.

[0120] Referring to Figures 4 to 6, in some embodiments, there are two pressing portions 230, which are spaced apart, and the limiting mechanism 300 is disposed between the two pressing portions 230.

[0121] Thus, when there are two pressing parts 230, by placing the limiting mechanism 300 between the two pressing parts 230, the limiting mechanism 300 can suppress the shaking of the button 200 at the two pressing parts 230 to be almost the same, thereby making the limiting mechanism 300 suppress the shaking of the entire button 200 more uniform.

[0122] Referring to Figures 4 to 6, in some embodiments, the electronic device may further include a latching member 400 disposed on the side of the button 200 near the button hole 110. The inner wall of the button hole 110 has a slot 111, and a portion of the latching member 400 extends into the slot 111. The slot 111 has a first slot wall 112 and a second slot wall 113 opposite each other in a first direction (X direction in Figure 6). The first slot wall 112 is closer to the opening of the button hole 110 relative to the second slot wall 113. When the button 200 is not subjected to external force, the latching member 400 abuts against the first slot wall 112. When the button 200 is pressed toward the contact point 151, when the latching member 400 abuts against the second slot wall 113, the button 200 stops moving, and the pressing part 230 can trigger the contact point 151. Thus, the travel of the button 200 along the first direction is the distance between the first slot wall 112 and the second slot wall 113.

[0123] In some embodiments, when the distance between the pressing part 230 of the button 200 and the contact point 151 is less than 1 / 3, and the distance between the first groove wall 112 and the second groove wall 113 of the slot 111 is greater than 1 / 3, the button 200 will have a play in the first direction, and the button 200 will wobble in the first direction when the button is not subjected to external force.

[0124] In this way, by setting the snap-fit ​​component 400 and setting the snap-fit ​​groove 111 corresponding to the snap-fit ​​component 400 on the inner side wall of the key hole 110, the snap-fit ​​component 400 moves along the first direction with the key 200, and the snap-fit ​​groove 111 can limit the displacement of the key 200 in the first direction by limiting the snap-fit ​​component 400, and can prevent the key 200 from coming out of the key hole 110, thereby improving the stability of the fit between the key 200 and the key hole 110 and improving the practicality of the electronic device.

[0125] Referring to Figures 4 to 6, in some embodiments, along the first direction (X direction in Figure 6), the distance from the second limiting member 320 to the plane where the key hole 110 is located is the first distance (L1 in Figure 6), and the distance from the first groove wall 112 of the card slot 111 to the plane where the key hole 110 is located is the second distance (L2 in Figure 6), and the first distance is less than the second distance.

[0126] In this way, by making the first distance smaller than the second distance, the distance from the second limiting member 320 to the plane where the key hole 110 is located can be smaller than the distance from the first groove wall 112 to the plane where the key hole 110 is located. This avoids the problem that the first limiting member 310 will dislodge from the limiting hole 321 of the second limiting member 320 due to the excessive travel of the key 200, and further cause the limiting mechanism 300 to fail in its function of limiting the keycap to shake.
