[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] The following combination Figures 1 to 4 The key structure proposed according to an embodiment of the present application is described. The key structure includes: a key module 200 , a key body 100 and an elastic member 400 .

[0030] Among them, the key module 200 is generally used to connect with the circuit board and is arranged inside the electronic device. The key module 200 is provided with a press detection element 2000, which is used to control certain functions of the electronic device when pressed, such as volume, interface selection, power switch, etc. The key body 100 is the movable main structure in the key structure, and the key body 100 includes: a keycap 101 and a support column 102. The support column 102 is connected to the side of the keycap 101 close to the press detection element 2000. The keycap 101 is used to directly contact the user, and the keycap 101 can move between a first position and a second position in the electronic device according to the user's press. Accordingly, the support column 102 also moves accordingly in the process of the keycap 101 moving between the first position and the second position. The elastic member 400 can be an elastic element, such as a spring, a spring, or the like. The elastic member 400 is configured with a limiting groove 405, which has an opening on a side wall perpendicular to the pressing direction. The side of the key module 200 facing the support column 102 or the side of the keycap 101 near the pressing detection element 2000 passes through the limiting notch opening and engages with the limiting groove 405. Alternatively, the side of the key module 200 facing the support column 102 and the side of the keycap 101 near the pressing detection element 2000 both pass through the opening and engage with the limiting groove 405. The elastic member 400 contacts the end surface of the keycap 101 near the pressing detection element 2000, thereby providing a certain preload force for the entire key body 100.

[0031] The elastic member 400 has a first compressed state and a second compressed state, with the deformation corresponding to the first compressed state being smaller than the deformation in the second compressed state. Therefore, when the keycap 101 is not pressed, the elastic member 400 can ensure a certain preload force on the keycap 101. After the keycap 101 is pressed, the elastic member 400 can provide a certain rebound force on the keycap 101, solving the problem of resetting the keycap 101 and ensuring the performance of the key structure.

[0032] During the movement of the keycap 101 between the first position and the second position, the state of the key structure can be correspondingly adjusted to control the key structure to switch between the first state and the second state.

[0033] Specifically, when the user moves the keycap 101 to the first position, the support column 102 separates from the press detection element 2000. At this time, the key structure is in the first state, for example, the key structure is in the inactive state, and the electronic device does not receive the control command output by the key structure. During this process, the elastic member 400 is in the first compression state under the pressure of the keycap 101, and the elastic member 400 provides a certain preload force for the keycap 101. This improves the delicate problem of key shaking. When the user moves the keycap 101 to the second position, the support column 102 contacts the press detection element 2000. At this time, the key structure is in the second state, for example, the key structure is in the active state, and the electronic device receives the control command output by the key structure. During this process, the elastic member 400 is in the second compression state under the pressure of the keycap 101, and the elastic member 400 provides a certain rebound force for the keycap 101. This avoids the problem that the key return stroke is blocked due to the small rebound force of the press detection element 2000, which affects the key performance.

[0034] In an embodiment of the present application, a key structure includes a key module, a key body, and an elastic member. A support column is provided on the keycap, and the elastic member is brought into contact with the side of the keycap facing the pressure detection element. The elastic member is configured with a limit groove, and the limit groove has an opening on a side wall perpendicular to the pressing direction. The side of the key module facing the support column and / or the side of the keycap near the limit notch pressing the detection element passes through the opening and engages with the limit groove. The elastic member is brought into contact with an end face of the keycap near the pressure detection element. When the keycap is in a first position, the support column is separated from the pressure detection element, and the elastic member is in a first compressed state. When the keycap is in a second position, the support column is brought into contact with the pressure detection element, and the elastic member is in a second compressed state. Thus, a certain preload force can be ensured on the keycap when it is not pressed, and a certain rebound force can be given to the keycap after it is pressed, thereby solving the problem of keycap reset and ensuring the performance of the key structure.

[0035] In one example, if Figures 1 to 4 As shown, the position of the elastic member 400 can be adjusted according to actual needs.

[0036] For example, the limiting groove 405 can be used to connect the elastic part 400 to the side of the key module 200 facing the support column 102. At this time, the elastic part 400 does not move as a whole, and the elastic part 400 always contacts the side of the keycap 101 close to the pressing detection element 2000. Thus, the elastic part 400 always provides a certain pre-tightening force for the key body 100 as a whole.

[0037] When the user moves the keycap 101 to the first position, the support column 102 separates from the pressure detection element 2000, and the elastic member 400 remains connected to the key module 200 and supported between the key module 200 and the keycap 101. The elastic member 400 is pressed into a first compressed state by the keycap 101, providing a certain preload force for the keycap 101. When the user moves the keycap 101 to the second position, the support column 102 contacts the pressure detection element 2000, and the elastic member 400 is pressed into a second compressed state by the keycap 101, providing a certain rebound force for the keycap 101.

[0038] For another example, the limiting groove 405 can be used to connect the elastic member 400 to the side of the keycap 101 close to the press detection element 2000. At this time, the elastic member 400 moves along with the key body 100, and one end of the elastic member 400 always contacts the side of the keycap 101 close to the press detection element 2000, and the other end of the elastic member 400 can contact the key module 200 or the middle frame. In this way, the elastic member 400 always provides a certain pre-tightening force for the key body 100 as a whole.

[0039] When the user moves the keycap 101 to the first position, the support column 102 separates from the pressure detection element 2000, and the elastic member 400 moves along with the key body 100, supported between the key module 200 and the keycap 101. The elastic member 400 is pressed into a first compressed state by the keycap 101, providing a certain preload force for the keycap 101. When the user moves the keycap 101 to the second position, the support column 102 contacts the pressure detection element 2000, and the elastic member 400 is pressed into a second compressed state by the keycap 101, providing a certain rebound force for the keycap 101.

[0040] In addition, one end of the elastic member 400 can be connected to the side of the keycap 101 close to the pressure detection element 2000 by using the limiting groove 405, and the other end of the elastic member 400 can be connected to the side of the key module 200 facing the support column 102 by using the limiting groove 405. In this way, the elastic member 400 is always supported between the key module 200 and the keycap 101.

[0041] When the key cap 101 is a long key cap, key failure is likely to occur due to the seesaw phenomenon. Figures 1 to 4 As shown, the elastic member 400 contacts both ends of the keycap 101 near the end surface of the pressure detection element 2000, thereby providing elastic force to the keycap 101 at two locations.

[0042] When the keycap 101 is in the first position, the elastic member 400 provides a certain pre-tightening force for the keycap 101. Both ends of the elastic member 400 are in the first compression state, and the elastic member 400 provides a certain pre-tightening force for two locations on the keycap 101, thereby improving the delicate problem of key shaking.

[0043] When the keycap 101 is in the second position, the support column 102 conflicts with the press detection element 2000, and at least one end of the elastic member 400 is in the second compression state. The elastic member 400 provides a certain rebound force for the keycap 101 to avoid the key return being blocked due to the small rebound force of the press detection element 2000.

[0044] Specifically, two elastic members 400 may be provided, namely a first elastic member 401 and a second elastic member 402. The first elastic member 401 and the second elastic member 402 are respectively connected to the left and right sides of one end surface of the keycap 101 close to the pressure detection element 2000.

[0045] The first elastic member 401 is connected to the left side of the keycap 101, and the second elastic member 402 is connected to the right side of the keycap 101. When the keycap 101 is not pressed, the first elastic member 401 provides a preload on the left side of the keycap 101, while the second elastic member 402 provides a preload on the right side of the keycap 101. When the keycap 101 is pressed on the left side, the first elastic member 401 provides a certain amount of rebound force to the keycap 101, while when the keycap 101 is pressed on the right side, the second elastic member 402 provides a certain amount of rebound force to the keycap 101. When the keycap 101 is pressed in the middle, the first elastic member 401 and the second elastic member 402 simultaneously provide a certain amount of rebound force to the keycap 101. By placing the first elastic member 401 and the second elastic member 402 at two locations on the keycap 101, they provide balanced force, improving the problem of keycap 101 shaking and failure caused by hitting the 1 / 4 position.

[0046] Based on the above embodiments, in one embodiment, Figures 1 to 4 As shown, the elastic member 400 includes a limiting portion 403 and an elastic portion 404 connected to each other. The elastic portion can be an elastic structure such as a spring or a spring. The limiting portion 403 is configured with a limiting groove 405.

[0047] According to the connection position of the elastic member 400 , the positions of the limiting portion 403 and the elastic portion 404 can be adjusted.

[0048] When the elastic member 400 is connected to the key module 200, one end of the limiting portion 403 is connected to the key module 200 via the limiting groove 405, while the other end of the limiting portion 403 contacts the keycap 101 via the elastic portion 404. At this time, the elastic portion 404 always contacts the side of the keycap 101 closest to the pressure detection element 2000, thereby providing a certain preload force to the entire key body 100.

[0049] When the elastic member 400 is attached to the keycap 101, one end of the limiting portion 403 is connected to the keycap 101 via the limiting groove 405, while the other end of the limiting portion 403 contacts the key module 200 via the elastic portion 404. Similarly, at this time, the elastic portion 404 always contacts the side of the keycap 101 closest to the pressure detection element 2000, thereby providing a certain preload force to the entire key body 100.

[0050] When the user moves the keycap 101 to the first position, the support column 102 separates from the pressure detection element 2000. At this time, the key structure is in a first state, for example, the key structure is in an inactive state, and the electronic device does not receive the control command output by the key structure. During this process, the elastic portion 404 is in a first compressed state under the pressure of the keycap 101, and the elastic portion 404 provides a certain pre-tightening force for the keycap 101. When the user moves the keycap 101 to the second position, the support column 102 contacts the pressure detection element 2000. At this time, the key structure is in a second state, for example, the key structure is in an active state, and the electronic device receives the control command output by the key structure. During this process, the elastic portion 404 is in a second compressed state under the pressure of the keycap 101, and the elastic portion 404 provides a certain rebound force for the keycap 101. The deformation amount corresponding to the elastic part 404 in the first compression state is smaller than the deformation amount of the elastic part 404 in the second compression state. Therefore, when the keycap 101 is not pressed, the elastic part 404 can ensure a certain pre-tightening force for the keycap 101. After the keycap 101 is pressed, the elastic part 404 can give the keycap 101 a certain rebound force, thereby solving the reset problem of the keycap 101 and ensuring the performance of the key structure.

[0051] like Figure 4 As shown, the limiting portion 403 is entirely made of sheet metal and includes a base 4034, a first support plate 4031, a second support plate 4032, and a third support plate 4033. One end of the base 4034 is connected to the elastic portion 404; the first support plate 4031, the second support plate 4032, and the third support plate 4033 are connected in sequence, and the first support plate 4031, the second support plate 4032, and the third support plate 4033 are all connected to the other end of the base 4034. The other end of the base 4034 is constructed with a limiting slot 405 for connecting to the keycap 101.

[0052] When the keycap 101 is inserted into the retaining groove 405, the keycap 101 is connected to the elastic member 400. When the key module 200 is inserted into the retaining groove 405, the key module 200 is connected to the elastic member 400. The first support plate 4031, the second support plate 4032, and the third support plate 4033 are used to limit the movement of the elastic member 400 in three directions. To ensure that the position of the spring does not move during use, a retaining protrusion 4000 can be provided on the first support plate 4031, the second support plate 4032, or the third support plate 4033 to simultaneously limit and secure the position.

[0053] In order to fix the elastic member 400, as Figures 1 to 4 As shown, one of the elastic member 400 and the keycap 101 is provided with a stopper protrusion 4000, and the elastic member 400 is engaged with the keycap 101 via the stopper protrusion 4000. In other words, by providing the stopper protrusion 4000 on either the elastic member 400 or the keycap 101, the stopper protrusion 4000 can be used to secure the elastic member 400 and the keycap 101. Providing the stopper protrusion 4000 on the elastic member 400 facilitates removal of the elastic member 400, making it easier for the user to choose whether to install the elastic member 400.

[0054] In this embodiment, the limiting protrusions 4000 are provided on two opposite sides of the elastic member 400 . The provision of two elastic members 400 can increase the stability of the connection between the elastic member 400 and the keycap 101 .

[0055] Furthermore, one of the elastic member 400 and the keycap 101 is provided with a limiting protrusion 4000, and the other is provided with a limiting groove that matches the limiting protrusion 4000. The elastic member 400 is engaged with the keycap 101 via the limiting protrusion 4000 and the limiting groove.

[0056] For example, limiting protrusions 4000 can be provided on opposite sides of the elastic member 400, and limiting grooves can be provided on the outside of the keycap 101 at positions corresponding to the limiting protrusions 4000. When the limiting protrusions 4000 move into the limiting grooves, the elastic member 400 engages with the keycap 101. Thus, the elastic member 400 moves along with the key body 100, ensuring a certain preload force on the keycap 101 when it is not pressed, and providing a certain rebound force on the keycap 101 after it is pressed, thereby solving the problem of the keycap 101 returning to its original position and ensuring the performance of the key structure.

[0057] The present application also provides an electronic device. The electronic device may be a smartphone, a game console, a tablet computer, an e-book reader, or a wearable device. Of course, the electronic device may also be other devices, and the embodiments of the present invention are not limited thereto.

[0058] Take smartphones as an example. Figures 5 to 7As shown, the electronic device includes: a frame 500 and a key structure.

[0059] The frame 500 is provided with a first mounting slot 5010 and a second mounting slot 5020; a button hole 5000 is provided between the first mounting slot 5010 and the second mounting slot 5020. The button structure comprises a button module 200, a button body 100, and an elastic member 400. The button module 200 is generally used to connect to the circuit board of an electronic device and is disposed in the first mounting slot 5010 of the frame 500, and then in the second mounting slot 5020. The button module 200 is provided with a pressure detection element 2000, which is used to control certain functions of the electronic device when pressed.

[0060] The key body 100 includes a keycap 101 and a support column 102. The support column 102 is connected to the side of the keycap 101 near the pressure detection element 2000. The keycap 101 is designed to directly contact the user and can move between a first position and a second position in the electronic device in response to the user's pressure. Accordingly, the support column 102 moves accordingly as the keycap 101 moves between the first and second positions. The elastic member 400 can be an elastic element, such as a spring, a spring, or the like. The elastic member 400 is configured with a limiting groove 405, which has an opening on a side wall perpendicular to the pressing direction. The side of the key module 200 facing the support column 102 or the side of the keycap 101 near the pressing detection element 2000 passes through the limiting notch opening and engages with the limiting groove 405. Alternatively, the side of the key module 200 facing the support column 102 and the side of the keycap 101 near the pressing detection element 2000 both pass through the opening and engage with the limiting groove 405. The elastic member 400 contacts the end surface of the keycap 101 near the pressing detection element 2000, thereby providing a certain preload force for the entire key body 100.

[0061] In this embodiment, the keycap 101 is movably arranged in the first mounting groove 5010 along the direction of the key hole 5000, the elastic member 400 is arranged between the keycap 101 and the side wall of the first mounting groove 5010, the support column 102 is passed through the key hole 5000, and the key module 200 is arranged in the second mounting groove 5020.

[0062] During the movement of the keycap 101 between the first position and the second position, the state of the key structure can be correspondingly adjusted to control the key structure to switch between the first state and the second state.

[0063] Specifically, when the user moves the keycap 101 to the first position, as shown in FIG. Figure 6As shown, the support column 102 is separated from the press detection element 2000. At this time, the key structure is in the first state, for example, the key structure is in the inactive state, and the electronic device does not receive the control command output by the key structure. During this process, the elastic member 400 is in the first compression state under the pressure of the keycap 101, and the elastic member 400 provides a certain pre-tightening force for the keycap 101. When the user moves the keycap 101 to the second position, as shown in FIG. Figure 7 As shown, the support column 102 passes through the key hole 5000 and contacts the press detection element 2000. At this time, the key structure is in the second state, for example, the key structure is in the activated state, and the electronic device receives the control command output by the key structure. During this process, the elastic member 400 is in the second compressed state under the pressure of the keycap 101, and the elastic member 400 provides a certain rebound force for the keycap 101. The deformation of the elastic member 400 corresponding to the first compressed state is smaller than the deformation of the elastic member 400 in the second compressed state. Therefore, when the keycap 101 is not pressed, the elastic member 400 can ensure a certain pre-tightening force on the keycap 101. After the keycap 101 is pressed, the elastic member 400 can provide the keycap 101 with a certain rebound force, solving the reset problem of the keycap 101 and ensuring the performance of the key structure.

[0064] In an embodiment of the present application, a key structure in an electronic device includes a key module, a key body, and an elastic member. A support column is provided on the keycap, and the elastic member is brought into contact with a side of the keycap facing a press detection element. The elastic member is configured with a limit groove, and the limit groove has an opening on a side wall perpendicular to the press direction. A side of the key module facing the support column and / or a side of the keycap near the limit notch press detection element passes through the opening and engages with the limit groove. The elastic member contacts an end face of the keycap near the press detection element. When the keycap is in a first position, the support column is separated from the press detection element, and the elastic member is in a first compressed state. When the keycap is in a second position, the support column contacts the press detection element, and the elastic member is in a second compressed state. Thus, a certain preload force can be ensured on the keycap when it is not pressed, and a certain rebound force can be given to the keycap after it is pressed, thereby solving the keycap reset problem and ensuring the performance of the key structure.

[0065] In an example provided in this application, Figures 4 to 7 As shown, the electronic device further includes an elastic limiter 600. A limit notch 1020 is provided at one end of the keycap 101 perpendicular to the key hole 5000. One end of the elastic limiter 600 is connected to the side wall of the first mounting groove 5010, and the other end of the elastic limiter 600 is disposed in the limit notch 1020. The elastic limiter 600 is used to limit the range of movement of the keycap 101, so that the keycap 101 can only move between the first position and the second position.

[0066] To limit the movement of the keycap 101, limiting notches 1020 may be provided at both ends of the keycap 101 perpendicular to the keyhole 5000, and two elastic limiting members 600 may be provided accordingly. One end of each elastic limiting member 600 is connected to the sidewall of the corresponding first mounting groove 5010, and the other end of the elastic limiting member 600 is disposed in the corresponding limiting notch 1020.

[0067] When the user moves the keycap 101 to the first position, Figure 6 As shown, the support column 102 is separated from the press detection element 2000. During this process, the elastic member 400 is in a first compression state under the pressure of the keycap 101. The elastic member 400 provides a certain pre-tightening force for the keycap 101. At the same time, the elastic limit member 600 clamps the keycap 101 to prevent the keycap 101 from moving out of the frame 500.

[0068] When the user moves the keycap 101 to the second position, as shown in FIG. Figure 7 As shown, the elastic stopper 600 blocks the keycap 101, preventing it from moving further into the frame 500. The support column 102 passes through the key hole 5000 and contacts the pressure detection element 2000. At this time, the key structure is in the second state. During this process, the elastic member 400 is in the second compressed state under the pressure of the keycap 101. The elastic member 400 provides a certain amount of rebound force for the keycap 101, causing it to move back to the first position.

[0069] In an example provided in this application, Figures 4 to 7 As shown, the electronic device further includes a seal 300, which is mounted on the support column 102. The seal 300 can be made of a waterproof material, such as a silicone ring or liquid injection silicone. During movement of the keycap 101 between the first and second positions, the seal 300 is at least partially disposed within the key hole 5000, thereby achieving a waterproof function.

[0070] Since the sealing member 300 is disposed in the key hole 5000 , which causes the key pressing resistance to be too large, the elastic member 400 can give the key cap 101 a certain rebound force, thereby solving the reset problem of the key cap 101 and ensuring the performance of the key structure.

[0071] In order to facilitate the placement of the elastic member 400 , a support foot 1010 is constructed on one side of the keycap 101 close to the press detection element 2000 . One end of the elastic member 400 is connected to the support foot 1010 , and the other end of the elastic member 400 contacts the side wall of the first installation groove 5010 .

[0072] When the keycap 101 is a long keycap, two supporting feet 1010 can be constructed on the side of the keycap 101 close to the press detection element 2000, and two elastic parts 400 are correspondingly arranged. One end of the two elastic parts 400 is connected to the corresponding supporting feet 1010, and the other end of the two elastic parts 400 is in conflict with the side wall of the first mounting groove 5010.

[0073] Specifically, see Figure 3 The two elastic members 400 are respectively a first elastic member 401 and a second elastic member 402. The first elastic member 401 is connected to the left side of the keycap 101, and the second elastic member 402 is connected to the right side of the keycap 101. When the keycap 101 is not pressed, the first elastic member 401 can ensure the pre-tightening force on the left side of the keycap 101, and the second elastic member 402 can ensure the pre-tightening force on the right side of the keycap 101. After pressing the keycap 101 on the left side, the first elastic member 401 can give the keycap 101 a certain rebound force, and after pressing the keycap 101 on the right side, the second elastic member 402 can give the keycap 101 a certain rebound force. After pressing the keycap 101 in the middle, the first elastic member 401 and the second elastic member 402 can simultaneously give the keycap 101 a certain rebound force. By respectively arranging the first elastic member 401 and the second elastic member 402 at two positions on the keycap 101, the first elastic member 401 and the second elastic member 402 can provide balanced forces, thereby improving the problem of the keycap 101 shaking and the failure caused by striking at the 1 / 4 position.
