Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasound device and its control panel and button structure. Background Technology

[0002] Currently, the control panel of ultrasound equipment typically includes a button structure, which generally consists of a button cap, a silicone button, and a dome switch. Pressing the button cap triggers the dome switch to realize the function of the button structure, and the elasticity of the silicone button allows the button structure to be reset.

[0003] Most existing silicone buttons use a flat elastic arm design. While flat elastic arm buttons offer stable pressing, their poor elasticity results in a sluggish button reset. Additionally, to facilitate doctor operation, existing buttons utilize low-force elastic components. Due to the low force applied to these elastic buttons, the button caps become soft, leading to poor stability and negatively impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of poor button rebound and unstable button structure in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a button structure for an ultrasonic device, for installation on the main body of a control panel. The button structure includes: a resilient button disposed on the main body; the resilient button includes a body and a support member, the support member being annular, its inner edge connected to one end edge of the body, and its outer edge connected to the main body; the support member includes connected, annular, resilient portions and connecting portions, the surface of the connecting portion being inclined, the surface of the resilient portion being arc-shaped, the side of the connecting portion facing away from the resilient portion connected to the main body, and the side of the resilient portion facing away from the connecting portion... One side is used for connection with the main body of the panel; a button cap is disposed on the outside of the main body; a trigger member is used for electrical connection to the control board of the control panel, the trigger member is arranged on the side of the main body away from the button cap, and there is a gap between the trigger member and the end of the main body; wherein, when an external force is applied to the button cap to press the elastic button, the support member undergoes elastic deformation, and the end of the main body can approach and abut against the trigger member to form a trigger signal, which can be transmitted to the control board; when the external force is released, the elastic part and the connecting part can provide a rebound force to the main body, so that the elastic button is reset.

[0006] In some embodiments, the body includes a pressing part and a trigger head, the trigger head being disposed toward the trigger member, the trigger head being used to abut against the trigger member and generate a trigger signal.

[0007] In some embodiments, the side wall of the pressing portion near the trigger is recessed with an annular groove, and the trigger head extends from the bottom wall of the annular groove toward the trigger.

[0008] In some embodiments, the diameter of the trigger head gradually decreases in the direction of the button cap toward the trigger member; and / or, the diameter of the cross-section of the trigger head is 3mm-5mm; and / or, the angle between the outer sidewall of the trigger head and the central axis of the trigger head is 10°-20°; and / or, the height of the trigger head is 5mm-10mm.

[0009] In some embodiments, the angle between the connecting portion and the panel body is 10°-20°; and / or, the width of the projection of the connecting portion onto the panel body is 3.5mm-6mm; and / or, the height of the elastic portion is 1.1mm-3mm.

[0010] In some embodiments, when the external force on the keycap is released, the inner wall of the keycap abuts against the end wall of the body, causing the deformation of the support member to be 0.3mm-0.5mm; the gap between the trigger head and the trigger member is 0.3mm-0.6mm, and the gap between the trigger head and the trigger member is greater than the deformation of the support member when pressed by the keycap.

[0011] In some embodiments, the end face of the body facing the keycap is recessed with an adapter mounting groove, and the key structure further includes an adapter, which includes a fixed part and a limiting part connected to each other, the limiting part being snapped into the adapter mounting groove; the keycap is provided with a mounting part, and the fixed part can be connected to the mounting part.

[0012] In some embodiments, there are multiple adapters, and the shapes of the fixing portions of the multiple adapters are different; there are multiple keycaps, and the shapes of the mounting portions of the multiple keycaps are different; the fixing portions of the multiple adapters and the mounting portions of the multiple keycaps are adapted to each other in a one-to-one correspondence.

[0013] This application also provides a control panel, which includes: a panel body; a button structure mounted on the panel body, wherein the button structure adopts the button structure described above; the control panel further includes a PCB board, wherein the PCB board is electrically connected to the control motherboard of the control panel; and a trigger element disposed on the PCB board and electrically connected to the PCB board.

[0014] This application also provides an ultrasonic device, which includes: a device host; an ultrasonic probe for transmitting and receiving ultrasonic signals, the ultrasonic probe being electrically connected to the device host; a control panel, which adopts the control panel described above, the control panel being electrically connected to the device host; and a display screen, which is electrically connected to the device host, the display screen being used to display the data results detected by the ultrasonic probe.

[0015] As can be seen from the above technical solution, this utility model has at least the following beneficial effects:

[0016] This utility model provides an ultrasonic device and its control panel and button structure. The button structure is installed on the main body of the control panel and includes: a resilient button, a button cap, and a trigger element. By utilizing a ring-shaped connecting part at the support member, one side of the connecting part is connected to the main body. When an external force is applied to the button cap, the button cap moves the main body towards the trigger element, causing the side of the connecting part away from the resilient part to deform under force. When the external force is released, the connecting part provides a rebound force to the main body. The outer surface of the connecting part is inclined, and the main body is located on one side of the connecting part, resulting in a large rebound force and a strong rebound feel for the button cap, allowing it to rebound quickly. The elastic part is connected to the main body on the side away from the connecting part, and its surface is arc-shaped. The elastic part provides a rebound force to the main body through the connecting part, and the arc shape of the elastic part makes the deformation smoother, resulting in uniform force distribution during the rebound of the main body. This ensures the smoothness of the resilient button's rebound and prevents the button cap from wobbling. Attached Figure Description

[0031] Ultrasound equipment is widely used in the medical field to detect and image human tissues using ultrasound, thereby facilitating the diagnosis and treatment of physiological and pathological conditions.

[0032] Most existing silicone buttons use a flat elastic arm design. While flat elastic arm buttons offer stable pressing, their poor elasticity results in a sluggish button reset. Additionally, to facilitate doctor operation, existing buttons utilize low-force elastic components. Due to the low force applied to these elastic buttons, the button caps become soft, leading to poor stability and negatively impacting the user experience.

[0033] Please see Figure 1 As shown, in some embodiments, this utility model provides an ultrasonic device 100, which includes an ultrasonic probe, a device host 30, a control panel 10, and a display screen 20. The ultrasonic probe is used to transmit and receive ultrasonic signals. The device host 30 is electrically connected to the ultrasonic probe. The control panel 10 is electrically connected to the device host 30. The display screen 20 is electrically connected to the device host 30 and is used to display data results.

[0034] Please see Figure 2 As shown, in some embodiments, the control panel 10 is electrically connected to the device host 30 for controlling the operation of the ultrasound device 100. The control panel 10 includes a panel body 2 and a button structure 1.

[0035] In some embodiments, the panel body 2 may be plate-shaped. A button structure 1 may be disposed on the panel body 2. A buttonless area may be disposed on the panel body 2. The buttonless area may be located on the side of the button structure 1 closer to the user. The buttonless area may also be located at the end of the panel body 2 closer to the user to support the user's wrist and facilitate user operation.

[0036] Please see Figures 2 to 8 As shown, in some embodiments, the button structure 1 includes a button cap 11, a spring button 12, and a trigger 13.

[0037] In some embodiments, the button cap 11 may be disposed on the panel body 2. The panel body 2 may have a buttonless area. The buttonless area may be located on the side of the button cap 11 closer to the user.

[0038] In some embodiments, multiple button caps 11 may be provided. These multiple button caps 11 may be spaced apart on the panel body 2 and located on the side away from the user from the buttonless area. The multiple button caps 11 have different functions, enabling the user to control the ultrasound device 100 via multiple buttons. A touch display screen 20 is located on the upper side of the panel body 2 for touch-sensitive display.

[0039] In some embodiments, the multiple keycaps 11 can be of different shapes. Different shaped keycaps 11 can have different functions. Therefore, users can quickly understand the function of the keycaps 11 based on their different shapes, thereby improving the efficiency and accuracy of user operation.

[0040] It should be noted that the multiple button caps 11 can be in the shape of a strip, a circle, or other irregular shapes, and there are no restrictions here.

[0041] It should be noted that in some other embodiments, the multiple button caps 11 may also have the same shape. The sizes of the multiple button caps 11 may be different. Button caps 11 of different sizes may have different functions. Therefore, users can quickly understand the function of the button caps 11 based on their different sizes, thereby improving the efficiency and accuracy of user operation.

[0042] Please see Figure 8 As shown, in some embodiments, the panel body 2 may include a PCB board 21. The PCB board 21 may be electrically connected to the control motherboard on the panel body 2. The PCB board 21 may be located below the button cap 11. When the user presses the button cap 11, the button cap 11 can descend and abut against the PCB board 21, thereby triggering the button's function through the PCB board 21.

[0043] In some embodiments, the panel body 2 may include a panel shell 22. The panel shell 22 has an internal mounting space. The PCB board 21 may be disposed inside the panel shell 22. Thus, the panel shell 22 can protect the PCB board 21 from damage.

[0044] In some embodiments, the panel body 2 may include a silicone plate 23. The silicone plate 23 may be disposed inside the panel housing 22.

[0045] Please see Figures 2 to 8 As shown, in some embodiments, the elastic button 12 can be disposed on the panel body 2, and the elastic button 12 can be disposed below the button cap 11. The elastic button 12 can be disposed between the silicone plate 23 and the button cap 11. The elastic button 12 can be elastic. The elastic button 12 can be disposed above the PCB board 21. When the button cap 11 is pressed, the button cap 11 descends towards the silicone plate 23, and the button cap 11 can press down on the elastic button 12, thereby abutting against the PCB board 21, and thus triggering the button function through the PCB board 21. When the button cap 11 is released, the elastic button 12 can rebound the button cap 11, causing the button cap 11 to rise away from the silicone plate 23, so that the button cap 11 returns to its original position for the user to press again.

[0046] In some embodiments, the trigger 13 may be located on the side of the body 121 away from the keycap 11. The trigger 13 may be electrically connected to the control body of the control panel 10. Specifically, the trigger 13 may be located on the PCB board 21 and electrically connected to it. When the keycap 11 is pressed by an external force, the keycap 11 descends toward the trigger 13, pressing the elastic button 12 downwards, thereby abutting against the trigger 13 to form a trigger signal. The trigger signal can be transmitted to the control motherboard, thereby triggering the button's function. When the external force is released and the keycap 11 is released, the elastic button 12 can rebound the keycap 11, allowing it to reset for the user to press again.

[0047] In some embodiments, the trigger 13 can be a dome button. The dome button can be disposed on the PCB board 21 and can be electrically connected to the PCB board 21. When the button cap 11 is pressed by external force, the button cap 11 descends toward the dome button, and the button cap 11 can press down on the elastic button 12, thereby abutting against the dome button to form a trigger signal. The trigger signal can be transmitted to the control motherboard, thereby triggering the button's function through the control motherboard.

[0048] It should be noted that in some other embodiments, the trigger 13 may also be a tactile switch or other trigger button.

[0049] In some embodiments, the resilient button 12 may include a body 121 and a support member 122. The support member 122 may be annular, with its inner edge connected to one end edge of the body 121 and its outer edge connected to the silicone plate 23. Thus, the support member 122 can support the body 121 above the silicone plate 23.

[0050] In some other embodiments, the inner edge of the support member 122 is connected to one end edge of the body 121, and the outer edge of the support member 122 is connected to the panel body 2.

[0051] In some embodiments, the support 122 is integrally formed with the body 121, thereby reducing the number of molds required for production and thus reducing production costs.

[0052] It should be noted that in some other embodiments, a connecting hole may be provided inside the support member 122. One edge of the body 121 can be connected to the peripheral edge of the connecting hole. Thus, by connecting the peripheral edge of the connecting hole to the body 121, the connection between the body 121 and the support member 122 is made more stable.

[0053] In some embodiments, the support 122 is integrally formed with the silicone plate 23, thereby reducing the number of molds required for production and thus reducing production costs.

[0054] It should also be noted that in some other embodiments, the silicone plate 23 has mounting holes. The body 121 can be disposed opposite to the mounting holes. The outer edge of the support member 122 is connected to the peripheral edge of the mounting hole. Thus, by connecting the mounting hole and the outer edge of the support member 122, the support member 122 can support the body 121 above the mounting hole.

[0055] Please see Figures 2 to 10 As shown, in some embodiments, the support member 122 includes a connecting portion 1221 and an elastic portion 1222. The connecting portion 1221 may be annular. The elastic portion 1222 may be annular. The inner edge of the connecting portion 1221 is connected to the outer edge of the elastic portion 1222, the outer edge of the connecting portion 1221 is connected to one end edge of the body 121, and the inner edge of the elastic portion 1222 is connected to the silicone plate 23. The connecting portion 1221 is inclined, and its outer surface is beveled. The elastic portion 1222 is arc-shaped, and its outer surface is arc-shaped. The side of the connecting portion 1221 facing away from the elastic portion 1222 is connected to the body 121, and the side of the elastic portion 1222 facing away from the connecting portion 1221 is used to connect to the silicone plate 23. When the button cap 11 is pressed, the body 121 deforms the support member 122, causing the button cap 11 to move the body 121 toward the trigger member 13, thereby triggering the button's function. When the button cap 11 is released, the connecting part 1221 and the elastic part 1222 provide a rebound force, causing the button cap 11 to rise away from the trigger member 13, thus resetting the button cap 11 for the user to press again.

[0056] Therefore, by providing a ring-shaped connecting portion 1221 at the support member 122, with one side of the connecting portion 1221 connected to the body 121, when an external force is applied to the button cap 11, the button cap 11 drives the body 121 to move towards the trigger member 13, causing the side of the connecting portion 1221 away from the elastic portion 1222 to be subjected to force, resulting in deformation of both the connecting portion 1221 and the elastic portion 1222. When the external force is released, the connecting portion 1221 and the elastic portion 1222 can provide a rebound force to the body 121. Because the outer surface of the connecting portion 1221 is inclined and the body 121 is located on one side of the connecting portion 1221, the rebound force provided by the connecting portion 1221 is large, resulting in a strong rebound feel of the button cap 11, and thus enabling the button cap 11 to rebound quickly. The elastic part 1222 is connected to the silicone plate 23 on the side away from the connecting part 1221. The surface of the elastic part 1222 is arc-shaped. The elastic part 1222 can provide the body 121 with a rebound force through the connecting part 1221. The elastic part 1222 is arc-shaped, and the deformation of the elastic part 1222 is smoother. This makes the force on the body 121 uniform when it rebounds, thereby ensuring the stability of the rebound of the elastic button 12 and preventing the button cap 11 on the elastic button 12 from shaking.

[0057] Please see Figure 10 As shown, in some embodiments, the included angle between the connecting part 1221 and the silicone plate 23 of the panel body 2 is α, where 10° < α < 20°. Therefore, by setting the tilt angle of the connecting part 1221, the connecting part 1221 can ensure the rebound force on the body 121, enabling the body 121 to rebound, while also preventing the tilt angle of the connecting part 1221 from being too large, which would cause the body 121 to rebound unevenly.

[0058] Please see Figure 10 As shown, in some embodiments, the width of the projection of the connecting part 1221 onto the silicone plate 23 on the panel body 2 is b, where 3.5mm < b < 5mm. Therefore, by using the set width of the connecting part 1221, the rebound force of the connecting part 1221 on the body 121 is more reasonable, satisfying both the rebound feel of the button cap 11 and the stability of the body 121 during rebound.

[0059] Please see Figure 10 As shown, in some embodiments, the height of the elastic portion 1222 is h, where 1.1 mm < h < 3 mm. Therefore, by setting the height of the arc-shaped elastic portion 1222, the elastic portion 1222 can satisfy both the rebound feel of the button cap 11 and the stability of the body 121 during rebound.

[0060] Please see Figures 8 to 10As shown, in some embodiments, the body 121 has a trigger head 1211 protruding towards the trigger member 13. The trigger head 1211 can be disposed opposite to the trigger member 13. When the button cap 11 is pressed, the button cap 11 can drive the trigger head 1211 to move towards the trigger member 13, so that the trigger head 1211 can abut against the trigger member 13, thereby realizing the button function. By using the trigger head 1211 protruding towards the trigger member 13, the triggering of the button function can be made simpler and the operation of triggering the button function can be made more convenient.

[0061] Please see Figure 8 As shown, in some embodiments, an annular groove 1212 is recessed on the side wall of the body 121 near the trigger member 13. The trigger head 1211 extends from the bottom wall of the annular groove 1212 toward the trigger member 13. The annular groove 1212 is annular in shape and surrounds the periphery of the trigger head 1211. The annular groove 1212 is located between the trigger head 1211 and the peripheral side wall of the body 121. Therefore, the use of the annular groove 1212 reduces the cost of the body 121 and increases the rebound force of the body 121, thereby making the rebound of the body 121 more stable.

[0062] In some embodiments, the trigger 13 may be elastic. When the button cap 11 is pressed, the button cap 11 can drive the trigger head 1211 to move toward the trigger 13, causing the trigger head 1211 to abut against the trigger 13, thus deforming the trigger 13. When the deformation reaches the trigger stroke of the trigger 13, the internal circuit of the trigger 13 is energized, thereby realizing the function of the button. However, when the button cap 11 is released, the trigger 13 has a certain rebound force on the trigger head 1211, thereby improving the tactile feedback of the button cap 11. At the same time, by utilizing the elasticity of the trigger head 1211, the button stroke can be increased through the deformation of the trigger head 1211, thereby preventing accidental activation of the button function by pressing the button cap 11.

[0063] In some embodiments, the diameter of the trigger head 1211 gradually decreases in the direction close to the trigger member 13.

[0064] Please see Figure 10 As shown, in some embodiments, the diameter of the cross-section of the trigger head 1211 is f, where 3mm < f < 5mm. This allows the trigger head 1211 to be positioned opposite the trigger member 13 when it abuts against it. Consequently, when the trigger head 1211 rebounds against the keycap 11, the deformation of the trigger head 1211 increases the key travel, thus preventing accidental activation of the keycap 11 and avoiding a short travel distance that would affect the tactile feedback of the keycap 11.

[0065] Please see Figure 10 As shown, in some embodiments, the angle between the outer wall of the trigger head 1211 and the central axis of the trigger head 1211 is β, where 10° < β < 20°. Therefore, by setting the angle between the outer wall of the trigger head 1211 and the central axis of the trigger head 1211, the diameter of the trigger head 1211 away from the trigger member 13 is larger than the diameter of the trigger head 1211 near the trigger member 13. This makes the end of the trigger head 1211 near the trigger member 13 more prone to deformation, thereby increasing the key travel. This helps prevent accidental activation of the keycap 11 and avoids affecting the tactile feedback of the keycap 11 due to a short travel distance.

[0066] Please see Figure 10 As shown, in some embodiments, the height of the trigger head 1211 is c, where 5mm < c < 10mm. Therefore, by limiting the height of the trigger head 1211, its elasticity is kept within a set range, ensuring both the rebound force of the trigger head 1211 on the keycap 11 and a smoother rebound of the keycap 11. Simultaneously, by deforming the trigger head 1211, the key travel of the keycap 11 is altered, thereby preventing accidental activation of the key's function and avoiding any impact on the tactile feedback of the keycap 11 due to an excessively short travel.

[0067] In some embodiments, when the keycap 11 is placed on the body 121, the keycap 11 can press the body 121, causing the support member 122 to deform. The deformation of the support member 122 is d, where 0.3mm < d < 0.5mm. This allows the support member 122 to generate a rebound force, ensuring that the keycap 11 and the body are in close contact. Simultaneously, pressing the keycap 11 causes the body 121 to descend synchronously, preventing further deformation of the body 121 when the keycap 11 is pressed. This reduces the relative movement between the keycap 11 and the body 121, ensuring synchronized movement of the body 121 and the keycap 11.

[0068] Please see Figure 8As shown, in some embodiments, the gap between the trigger head 1211 and the trigger member 13 is e, where 0.3mm < e < 0.6mm. Furthermore, the gap e between the trigger head 1211 and the trigger member 13 is greater than or equal to the deformation d of the support member 122 when pressed by the keycap 11. Therefore, after the keycap 11 is pre-pressed, the gap between the trigger head 1211 and the trigger member 13 is 0-0.1mm. This avoids the gap e between the trigger head 1211 and the trigger member 13 becoming too large and causing a free travel, allowing the trigger head 1211 to abut against the trigger member 13 more quickly when the keycap 11 is pressed, thus enabling the trigger member 13 to trigger the button function more quickly. Simultaneously, when the keycap 11 is released, the rebound of the elastic part 1222 and the connecting part 1221 allows the trigger head 1211 to reset, making the reset of the trigger head 1211 more stable and improving the smoothness of the movement of the body 121.

[0069] It should be noted that in some other embodiments, when the trigger stroke of the trigger 13 is between 0.5mm and 1.5mm, the button cap 11 and the body 121 can abut against each other, and the body 121 does not deform. Then, after the button cap 11 abuts against the trigger 13, the button cap 11 is released, and the elasticity of the trigger 13 can help the body 121 and the trigger head 1211 on the body 121 to reset, thereby realizing the reset of the body 121.

[0070] Please see Figures 2 to 7 As shown, in some embodiments, the button structure 1 may further include an adapter 14. The adapter 14 may include a fixing part 141 and a limiting part 142. The fixing part 141 may be connected to the button cap 11. An adapter mounting groove 1213 is recessed on the side wall of the body 121 away from the trigger member 13. The limiting part 142 can extend into and be limited within the adapter mounting groove 1213. Thus, by using the adapter 14, the button cap 11 and the body 121 can be fixedly connected, thereby improving the stability of the connection between the button cap 11 and the body 121.

[0071] In some embodiments, the cross-section of the limiting portion 142 may be triangular. The shape of the adapter mounting groove 1213 may be adapted to the limiting portion 142, thereby limiting the distance between the limiting portion 142 and the body 121 when the limiting portion 142 extends into and is limited within the adapter mounting groove 1213. Simultaneously, the adapter mounting groove 1213 can be used to position the limiting portion 142 during installation, improving the ease of installation.

[0072] It should be noted that in some other embodiments, the cross-section of the limiting part 142 may be square or other shapes, which are not limited here.

[0073] In some embodiments, the keycap 11 may be provided with a mounting portion opposite to the fixing portion 141. The mounting portion may be a mounting groove. By having the fixing portion 141 extend into and connect to the mounting portion, the keycap 11 can be fixedly connected to the adapter 14, thereby improving the stability between the keycap 11 and the body 121.

[0074] In some embodiments, multiple adapters 14 are provided, each with a corresponding fixing part 141, and the shape of the fixing part 141 on each adapter 14 is different; multiple keycaps 11 are provided, each with a corresponding mounting part, and the shape of the mounting part on each keycap 11 is different. The fixing parts 141 of the multiple adapters 14 are adapted to the mounting parts of the multiple keycaps 11 in a one-to-one correspondence. By adapting multiple fixing parts 141 with multiple mounting parts with different shapes, the multiple adapters 14 can adapt to multiple keycaps 11 of different shapes, thereby allowing keycaps 11 of different shapes to be fixedly connected to the main body 121 through the adapters 14. This allows each keycap 11 of different shapes to adapt to the same type of elastic button 12, thereby ensuring the consistency of the overall button force value of the same panel body 2 or a certain area, thereby improving the convenience of user operation and solving the problem of different pressing force values ​​due to inconsistent size and shape of keycaps 11.

[0075] Please see Figure 6 and Figure 7 As shown, in some embodiments, a limiting groove 1214 is formed on the peripheral sidewall of the body 121. The limiting groove 1214 can be located at the end of the body 121 away from the trigger member 13. The button cap 11 is provided with a limiting post 111 that matches the limiting groove 1214. When the button cap 11 is placed on the body 121, the limiting post 111 can extend into and be limited within the limiting groove 1214. Thus, through the limiting between the limiting groove 1214 and the limiting post 111, the button cap 11 and the body 121 can be stably installed. At the same time, by reasonably designing the limiting groove 1214 and the limiting post 111, the assembly accuracy and efficiency between the button cap 11 and the body 121 can be effectively improved, and human error can be reduced.

[0076] In some embodiments, multiple limiting grooves 1214 may be provided, and the multiple limiting grooves 1214 may be arranged at intervals around the periphery of the body 121. Multiple limiting posts 111 may be provided, and the multiple limiting posts 111 may correspond one-to-one with the multiple limiting grooves 1214. When the button cap 11 is placed on the body 121, the multiple limiting posts 111 can simultaneously extend into and be limited within the multiple limiting grooves 1214, thereby further improving the stability of the connection between the button cap 11 and the body 121.

[0077] As can be seen from the above technical solution, this utility model has at least the following beneficial effects:

[0078] This invention provides an ultrasonic device 100, its control panel 10, and a button structure 1. The button structure 1 is mounted on the panel body 2 of the control panel 10 and includes: a resilient button 12, a button cap 11, and a trigger element 13. By utilizing a ring-shaped connecting portion 1221 provided at the support member 122, with one side of the connecting portion 1221 connected to the body 121, when an external force is applied to the button cap 11, the button cap 11 drives the body 121 to move towards the trigger element 13. This causes the side of the connecting portion 1221 away from the resilient portion 1222 to be subjected to force, resulting in deformation of both the connecting portion 1221 and the resilient portion 1222. When the external force is released, both the connecting part 1221 and the elastic part 1222 can provide a rebound force to the body 121. Because the outer surface of the connecting part 1221 is inclined and the body 121 is located on one side of the connecting part 1221, the rebound force provided by the connecting part 1221 is large, resulting in a strong rebound feel for the button cap 11, allowing it to rebound quickly. The side of the elastic part 1222 away from the connecting part 1221 is connected to the panel body 2, and the surface of the elastic part 1222 is arc-shaped. The elastic part 1222 can provide a rebound force to the body 121 through the connecting part 1221. Furthermore, the arc shape of the elastic part 1222 makes its deformation smoother, resulting in even force distribution when the body 121 rebounds. This ensures the stability of the rebound of the elastic button 12, preventing the button cap 11 on the elastic button 12 from wobbling.

[0079] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
