[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0039] The electronic device 100 according to an embodiment of the present application is described below with reference to the accompanying drawings. It is understandable that the electronic device 100 can be a terminal device such as a mobile phone, a tablet computer, a laptop computer, or a smart wearable device such as a smart watch, a smart headset, or a smart glasses.

[0040] like Figure 1 and Figure 2 As shown, the electronic device 100 according to an embodiment of the present application includes a housing 1 and a button assembly 3 .

[0041] The housing 1 may include a middle frame formed into a frame structure, and a receiving space 11 is defined inside the middle frame. The receiving space 11 may be used to receive functional components of the electronic device 100, such as a motherboard, a camera, a sensor, a memory, an antenna, and other components. The middle frame has a first end face 12 and a second end face (e.g. Figure 1 The first end surface 12 and the second end surface can respectively cooperate with the front structure and the back structure of the electronic device 100. It can be understood that when the electronic device 100 is in use, the structure facing the user is the front structure, and the structure facing away from the user is the back structure. For example, the front structure can be a display screen, and the back structure can be a back cover.

[0042] A trigger component 2 is provided in the shell 1, and the trigger component 2 can be electrically connected to the functional device of the electronic device 100. After the trigger component 2 receives the trigger signal from the button assembly 3, the trigger signal can be sent to the corresponding functional device, so that the functional device responds, thereby realizing the control of the functional device of the electronic device 100.

[0043] The key assembly 3 includes a key cap 31 and two key columns 32. The key cap 31 is provided with two pressing portions 311. The two key columns 32 are arranged in the length direction of the key cap 31 (for example, Figure 1 The two pressing portions 311 are arranged in the x direction in FIG. 1 , and the two pressing portions 311 correspond to the two button posts 32 one by one. That is, each pressing portion 311 corresponds to one button post 32.

[0044] In some embodiments of the present application, the trigger member 2 may be one, and the trigger member 2 may be formed into a long strip, and the two button columns 32 are respectively opposite to two different parts of the trigger member 2. Optionally, the two different parts of the trigger member 2 may respectively correspond to different functional devices, so that different functional devices can be controlled by the button assembly 3.

[0045] In some other embodiments of the present application, there may be two trigger members 2, and each button column 32 corresponds to one trigger member 2. The two trigger members 2 may correspond to different functional devices, respectively. Thus, different functional devices can be controlled by the button assembly 3.

[0046] The button column 32 passes through the housing 1 and is opposite to the trigger member 2. An elastic pad 33 is provided between each button column 32 and the button cap 31. The button cap 31 is rotatably arranged on the housing 1 so as to drive the button column 32 to move toward the direction close to the trigger member 2 when one of the pressing portions 311 is pressed, so as to trigger the trigger member 2 through the button column 32. Specifically, when the pressing portion 311 is pressed, the button column 32 corresponding to the pressing portion 311 can move along with the pressing portion 311 toward the direction close to the trigger member 2 so as to trigger the trigger member 2 through the button column.

[0047] In the initial state (i.e., the state where the trigger member 2 is not triggered), the button column 32 may be in contact with the trigger member 2, or may be spaced apart from the trigger member 2. When the pressing portion 311 on the button cap 31 is pressed, the pressing force may be transmitted to the button column 32 through the elastic pad 33 between the pressing portion 311 and the button column 32, so that the button column 32 triggers the trigger member 2 to send an electrical signal, thereby controlling the electronic device 100.

[0048] During the research process, the applicant of the present application discovered that the button assembly 3 in the related technology, since the button cap 31 and the button column 32 are an integral structure, or the button cap 31 and the button column 32 are fixedly connected by a structure such as a thread, when the button cap 31 is pressed, if one end of the button part is pressed, it will cause the other end to warp, causing the button column 32 to tilt, and the button is prone to getting stuck.

[0049] To this end, the applicant of the present application sets an elastic pad 33 between the key column 32 and the key cap 31, designs the key cap 31 and the key column 32 as a non-integrated structure, and makes the key cap 31 and the key column 32 movably connected. Figure 5 and Figure 6 As shown in the figure, whether the middle or side of the pressing portion 311 is pressed, the button column 32 and the trigger member 2 (such as a DOME pot) always maintain vertical movement, and the button column 32 will not be tilted, thereby ensuring the key feel and key function. At the same time, by adding an elastic pad 33 between the button cap 31 and the button column 32, when the electronic device 100 falls or has an impact, the elastic pad 33 can play a buffering role, protect the trigger member 2, and prevent the trigger member 2 from being damaged by force.

[0050] Specifically, refer to Figure 5 and Figure 6 As shown, when a pressing portion 311 in the button cap 31 receives a pressing force in a direction offset from the central axis of the button column 32, one end of the elastic pad 33 is compressed and deformed, while the other end of the elastic pad 33 may be tensilely deformed, that is, the elastic pad 33 absorbs the tilting force on the pressing portion 311 and effectively prevents the tilting force on the pressing portion 311 from being transmitted to the button column 32, thereby preventing the button column 32 from tilting and ensuring that the button column 32 and the trigger member 2 always maintain vertical movement, so that the button column 32 can effectively trigger the trigger member 2, thereby avoiding the situation where the button is stuck.

[0051] In addition, the present application adopts a structure in which one button cap 31 corresponds to two button columns 32, the two buttons are combined into one, and the button cap 31 is set to a seesaw-like structure, so that the two ends of the button cap 31 can rotate relative to each other to input their own pressing signals, thereby realizing a non-linked bidirectional button function (that is, the two button columns 32 correspond to different trigger signals, respectively). It is easy to install and occupies little space, which is beneficial to improving the utilization rate of the side wall of the shell 1, enhancing the overall design aesthetics of the product, and helping to reduce material costs, thereby reducing the overall cost of the button assembly 3.

[0052] According to the electronic device 100 of the embodiment of the present application, by arranging the elastic pad 33 between the key cap 31 and the key column 32, the elastic deformation performance of the elastic pad 33 is utilized to make the key cap 31 and the key column 32 relatively movable, so as to avoid the key column 32 being tilted and stuck when pressing the end of the key cap 31, thereby effectively preventing the key assembly 3 from failing and ensuring the effective pressing performance and pressing feel of the key assembly 3. At the same time, by adding the elastic pad 33 between the key cap 31 and the key column 32, when the electronic device 100 falls and has an impact, the elastic pad 33 can play a buffering role, protect the trigger member 2, and prevent the trigger member 2 from being damaged by force. In addition, the key assembly 3 in the present application adopts a structure in which a pair of key caps 31 correspond to two key columns 32, so as to realize the non-linked bidirectional key function, which is easy to install and occupies a small space, which is conducive to improving the utilization rate of the side wall of the housing 1, improving the overall design aesthetics of the product, and is conducive to reducing the material cost, thereby reducing the overall cost of the key assembly 3.

[0053] According to some embodiments of the present application, a button hole 13 is provided on the side wall of the housing 1, and at least a portion of the button assembly 3 is disposed in the button hole 13. Specifically, a portion of the button assembly 3 is disposed in the button hole 13, or the entire button assembly 3 is disposed in the button hole 13. Figure 1 In the example, a part of the key assembly 3 is arranged in the key hole 13, a part of the key cap 31 is arranged outside the key hole 13, and the outer surface of the key cap 31 protrudes from the outer surface of the side wall of the housing 1. Thus, it is convenient to press the key cap 31, so that the trigger member 2 can be conveniently triggered.

[0054] It can be understood that in some embodiments of the present application, the button column 32 can be directly penetrated on the side wall of the shell 1. In this case, the button cap 31 is arranged outside the shell 1. There is no need to open a button hole on the shell 1 to accommodate the button cap 31. The button cap 31 can be positioned by cooperating with the matching structure on the button cap 31 through the positioning structure (such as a positioning column, a positioning protrusion, a positioning block) provided on the outer surface of the side wall of the shell 1. The structure is simple and the processing is convenient.

[0055] In some embodiments of the present application, two protrusions protruding outward are provided on the outer surface of the key cap 31 to form two pressing portions 311. Figure 1 Combined with Figure 3 and Figure 4 The two raised portions are spaced apart from each other. Thus, it is convenient for the user to press the pressing portion 311, the pressing feel is improved, and the overall aesthetics of the key assembly 3 can be improved.

[0056] According to some embodiments of the present application, referring to Figure 4-Figure 6The button cap 31 is rotatably connected to the housing 1 through the positioning pin 4. The positioning pin 4 is located between the two button columns 32. A through first positioning hole 14 is provided on the side wall of the button hole 13. A second positioning hole 312 is provided on the button cap 31. The positioning pin 4 is inserted into the first positioning hole 14 and the second positioning hole 312. The central axis of the first positioning hole 14 and the second positioning hole 312 is along Figure 2 The first positioning hole 14 extends in the z direction, and the first positioning hole 14 may only penetrate the first end surface 12 of the shell 1, or may penetrate the first end surface 12 and the second end surface at the same time.

[0057] When the pressing part 311 on the key cap 31 is pressed, the two ends of the key cap 31 can rotate relative to each other with the positioning pin 4 as the fulcrum, thereby realizing a non-linked two-way key function. The structure is simple and occupies a small space, which is beneficial to improving the utilization rate of the side wall of the shell 1, enhancing the overall design aesthetics of the product, and helping to reduce material costs, thereby reducing the overall cost of the key assembly 3.

[0058] According to other embodiments of the present application, the key cap 31 may also be rotatably connected to the housing 1 via a ball shaft 51. The ball shaft 51 is fixed to one of the key hole 13 and the key cap 31, and a ball socket 52 is provided on the other of the key hole 13 and the key cap 31. The ball shaft 51 extends into the ball socket 52 and cooperates with the ball socket 52. When the pressing portion 311 on the key cap 31 is pressed, the two ends of the key cap 31 can rotate relative to each other with the ball shaft 51 as a fulcrum.

[0059] Specifically, when the ball shaft 51 is disposed in the key hole 13, the ball socket 52 is disposed on the key cap 31. When the ball shaft 51 is disposed on the key cap 31, the ball socket 52 is disposed in the key hole 13. Figure 7 and Figure 8 In the example, the ball shaft 51 is arranged on the inner bottom wall of the key hole 13 (i.e., the inner wall of the key hole 13 opposite to the key cap 31), an extension block 314 is arranged on the side surface of the key cap 31 facing the housing 1, and a ball socket 52 is arranged on the side surface of the extension block 314 opposite to the inner bottom wall of the key hole 13, and the ball socket 52 can be formed by the above-mentioned side surface of the extension block 314 being recessed in the direction of the key cap 31. Therefore, by cooperating with the ball shaft 51 and the ball socket 52, not only can the key cap 31 be assembled to the housing 1, but also the relative rotation between the key cap 31 and the housing 1 is realized, which has a simple structure and is easy to process.

[0060] In some other embodiments of the present application, the ball shaft 51 can also be arranged on the inner wall of the button hole 13 (for example, the side wall of the button hole 13 in the z direction), and the ball socket 52 is arranged on the side surface of the extension block 314 opposite to the inner wall of the button hole 13. Therefore, the button cap 31 can also be assembled to the shell 1 through the cooperation of the ball shaft 51 and the ball socket 52, and the relative rotation between the button cap 31 and the shell 1 can be achieved.

[0061] According to some other embodiments of the present application, the key cap 31 can also be rotatably connected to the housing 1 through a pivot assembly 6. The pivot assembly 6 includes a pivot shaft 61 and a pivot hole 62. The pivot shaft 61 extends into the pivot hole 62 and cooperates with the pivot hole 62. The pivot shaft 61 is arranged on one of the key hole 13 and the key cap 31, and the pivot hole 62 is arranged on the other of the key cap 31 and the key hole 13. When the pressing portion 311 on the key cap 31 is pressed, the two ends of the key cap 31 can rotate relative to each other with the pivot shaft 61 as a fulcrum.

[0062] Specifically, when the pivot shaft 61 is disposed in the key hole 13, the pivot hole 62 is disposed on the key cap 31. When the pivot shaft 61 is disposed on the key cap 31, the pivot hole 62 is disposed in the key hole 13. For example, Fig. 9 and Fig.10 In the example, the pivot shaft 61 is arranged in the key hole 13 and extends along the z direction, an extension block 314 is arranged on the side surface of the key cap 31 facing the housing 1, and a pivot hole 62 is arranged on the side surface of the extension block 314 opposite to the inner side wall of the key hole 13. Among them, an opening 621 can be arranged on the pivot hole 62, and the pivot shaft 61 can pass through the opening 621 and extend into the pivot hole 62 to cooperate with the pivot hole 62. Therefore, by setting the pivot assembly 6, not only can the key cap 31 be assembled to the housing 1, but also the relative rotation between the key cap 31 and the housing 1 is realized, and the structure is simple and the processing is convenient.

[0063] In other embodiments of the present application, the pivot axis 61 can also be arranged on the inner wall of the button hole 13 (for example, the side wall of the button hole 13 in the z direction), and the pivot hole 62 is arranged on the side surface of the extension block 314 opposite to the inner wall of the button hole 13. Thus, the button cap 31 can also be assembled to the shell 1 through the pivot assembly 6, and the relative rotation between the button cap 31 and the shell 1 can be achieved.

[0064] According to some embodiments of the present application, a receiving groove 313 is provided on a side surface of the key cap 31 facing the housing 1, and at least a portion of the elastic pad 33 is received in the receiving groove 313. It is understandable that a portion of the elastic pad 33 can be received in the receiving groove 313, that is, the depth of the receiving groove 313 is less than the thickness of the elastic pad 33, or the entire elastic pad 33 can be received in the receiving groove 313, that is, the depth of the receiving groove 313 is greater than or equal to the thickness of the elastic pad 33. Thus, it is convenient to assemble the elastic pad 33 onto the key cap 31, and the position of the elastic pad 33 can be stabilized to prevent the elastic pad 33 from moving.

[0065] In some embodiments of the present application, the elastic pad 33 is bonded to the key cap 31. Specifically, the elastic pad 33 can be bonded to the inner wall of the receiving groove 313 by double-sided tape or glue.

[0066] Optionally, the elastic pad 33 may be a silicone pad, a foam pad, etc. In some embodiments of the present application, the elastic pad 33 may be formed in a square, an elliptical, an oblong, etc. The thickness of the elastic pad 33 is uniform, and the thickness direction of the elastic pad 33 is substantially perpendicular to the side wall of the housing 1. Thus, the contact area between the elastic pad 33 and the key cap 31 can be increased, ensuring effective contact between the key cap 31 and the elastic pad 33, and effective contact between the key column 32 and the elastic pad 33.

[0067] According to some embodiments of the present application, two guide holes 15 are provided on the housing 1, and two button columns 32 are respectively disposed in the two guide holes 15, and the button columns 32 are clearance-matched with the guide holes 15. Figure 3-Figure 6 The guide hole 15 passes through the bottom wall of the button hole 13. When the pressing portion 311 is pressed, the end of the button column 32 away from the button cap 31 can pass through the guide hole 15 and contact the trigger member 2 to trigger the trigger member 2. Therefore, the movement of the button column 32 can be guided by the guide hole 15 to prevent the button column 32 from deviating during the movement, further ensuring that the button column 32 and the trigger member 2 always maintain vertical movement, ensuring the effective pressing performance and pressing feel of the button assembly 3.

[0068] According to some embodiments of the present application, an annular sealing ring 34 is provided on the outer peripheral wall of the button column 32, and the outer peripheral surface of the sealing ring 34 is abutted against the inner wall surface of the guide hole 15. The sealing ring 34 can effectively prevent water, dust, and impurities from entering the inner side of the housing 1 from the gap between the outer peripheral wall of the button column 32 and the inner peripheral side wall of the guide hole 15. In this way, the sealing performance of the electronic device 100 can be improved. For example, when the electronic device 100 is a smart watch, the sealing ring 34 is sealed between the button column 32 and the guide hole 15, so that the electronic device 100 can meet the 5ATM waterproof requirement.

[0069] In some embodiments of the present application, the sealing ring 34 may have elastic deformation properties. Optionally, the sealing ring 34 is a silicone member or a rubber member. The outer diameter of the sealing ring 34 in a naturally stretched state is greater than the inner diameter of the guide hole 15. During assembly, after the key column 32 enters the guide hole 15, the sealing ring 34 is compressed and deformed by the squeezing action of the inner peripheral side wall of the guide hole 15, so that the sealing ring 34 can be in close contact with the inner peripheral side wall of the guide hole 15 to a large extent, and the gap between the inner peripheral wall of the guide hole 15 and the outer peripheral wall of the key column 32 is blocked by the sealing ring 34.

[0070] It can be understood that since the button column 32 in the present application always maintains movement in a direction perpendicular to the trigger member 2, the situation of unilateral squeezing of the sealing ring 34 when the button column 32 is tilted is avoided, thereby further improving the sealing performance of the electronic device 100, and reducing the friction between the sealing ring 34 and the inner peripheral side wall of the guide hole 15, reducing the pressing force, and improving the pressing feel.

[0071] According to some embodiments of the present application, an annular groove 321 is provided on the outer peripheral wall of the button column 32, and the sealing ring 34 is sleeved in the annular groove 321. Thus, the position of the sealing ring 34 can be stabilized, and the sealing ring 34 can be prevented from slipping off the button column 32, thereby ensuring the sealing performance of the electronic device 100.

[0072] In some embodiments of the present application, an annular protrusion 16 is provided on the inner bottom wall of the button hole 13, and the annular protrusion 16 surrounds the outer circumference of the button column 32. Figure 4 , a part of the button column 32 is inserted into the annular protrusion 16. As a result, the inside of the annular protrusion 16 can be constructed as a part of the guide hole 15, which increases the length of the guide hole 15, improves the guiding effect of the guide hole 15, further avoids the button column 32 from running off during movement, and further ensures that the button column 32 and the trigger member 2 always maintain vertical movement, ensuring the effective pressing performance and pressing feel of the button assembly 3. According to some embodiments of the present application, one or more elastic reset members 351 are provided between each pressing portion 311 and the shell 1, and the elastic reset member 351 is configured to drive the pressing portion 311 to reset after the pressing portion 311 is pressed. In the description of the present application, "multiple" means two or more.

[0073] Specifically, the elastic reset member 351 can be configured to always drive the pressing portion 311 to move in a direction away from the trigger member 2. When the pressing portion 311 is pressed, the elastic reset member 351 is compressed to undergo elastic deformation and has a tendency to recover the deformation. When the pressing portion 311 is released, the pressing portion 311 moves in a direction away from the trigger member 2 under the driving force of the elastic reset member 351, so that the key cap 31 is reset. Optionally, the elastic reset member 351 is a spring, a torsion spring, an elastic silicone block or an elastic rubber block.

[0074] For example, in some embodiments of the present application, refer to Figure 2 Combined with Figure 3-Figure 6Two elastic reset members 351 are provided between each pressing portion 311 and the housing 1, and the two elastic reset members 351 are respectively located on both sides of the key column 32. The elastic reset members 351 are springs. For example, in the length direction or width direction of the key cap 31, the two springs can be located on both sides of the key column 32. Thus, the force on the key cap 31 can be uniform, which is conducive to improving the stability of the movement of the key column 32 and the key cap 31, thereby further improving the pressing feel of the key assembly 3.

[0075] According to some embodiments of the present application, at least one of the housing 1 and the button cap 31 is provided with a fixing groove for accommodating the elastic reset member 351. Thus, the position of the elastic reset member 351 can be stabilized, and the performance of the elastic reset member 351 is improved.

[0076] According to some embodiments of the present application, a limit platform 133 is provided in the button hole 13, and when the button cap 31 is pressed, the limit platform 133 stops and cooperates with the button cap 31. Specifically, when the button cap 31 is pressed, the limit platform 133 can stop and cooperate with a side surface of the button cap 31 close to the housing 1.

[0077] In some embodiments of the present application, the limit platform 133 can be formed in a ring shape, for example, the limit platform 133 can surround the inner wall of the key hole 13. It can be understood that in other embodiments of the present application, the limit platform 133 can be formed in a block shape, and there can be two limit platforms 133, and the two limit platforms 133 are arranged at intervals in the length direction of the key hole 13, and the two limit platforms 133 are respectively opposite to the two ends of the length direction of the key cap 31. In some other embodiments of the present application, the limit platform 133 can also be opposite to the middle part of the key cap 31. It should be noted that the "middle part of the key cap 31" in the present application should be understood in a broad sense, that is, the position between the two ends of the key cap 31 in the length direction can be understood as the middle part of the key cap 31.

[0078] For example, refer to Figure 4 and Figure 6 When the pressing portion 311 is pressed, after the key cap 31 rotates a certain angle, the end of the key cap 31 stops at the limit platform 133, and the limit platform 133 prevents the key cap 31 from continuing to rotate, so that the rotation angle and movement distance of the key cap 31 can be limited by the limit platform 133, avoiding the key cap 31 from rotating too much and causing excessive pressing on the trigger member 2, causing damage to the trigger member 2, effectively protecting the trigger member 2, and improving the reliability of the electronic device 100.

[0079] In some embodiments of the present application, when assembling the electronic device 100, the button column 32 with the sealing ring 34 can be first installed into the guide hole 15, and then the four elastic return members 351 can be respectively installed in the fixing grooves. The elastic return members 351 play the role of providing elastic force for the button cap 31. Then, the elastic pad 33 is fixed in the receiving groove 313 on the button cap 31, and then the button cap 31 is installed as a whole into the button hole 13. Finally, the positioning pin 4 is inserted into the first positioning hole 14 and the second positioning hole 312 to fix the entire button assembly 3 on the shell 1.
