[0001] The present disclosure relates to the technical field of buttons, and specifically, to a button assembly and an electronic device. Background Art

[0002] With the development of consumer electronics technology, the functions of electronic devices such as mobile phones are becoming increasingly rich. Users usually need to interact with the buttons of the electronic device to achieve quick operations of functions such as volume control, power on / off, quick photography, and screenshot.

When the user presses the button, the metal dome of the DOME sheet will be pressed down and contact the circuit board below the DOME sheet to achieve the conduction of the circuit, thereby triggering the corresponding function. However, since the metal dome of the DOME sheet needs to generate a large deformation to contact the circuit board, the user needs to apply a large force to the button to trigger the corresponding function of the electronic device.

[0016] Optionally, the mounting bracket has a pushing operation surface for a user to push the mounting bracket into the mounting groove, the connecting portion is arranged on a side of the mounting bracket away from the pushing operation surface, the mounting bracket is located between the pressure sensing portion and the external connection portion, and a second avoidance groove is further formed on the mounting bracket, and the second avoidance groove is for the external connection portion to pass through.

[0017] Optionally, the mounting bracket forms an avoidance notch for avoiding the connecting kink between the connecting portion and the external connection portion.

[0018] Optionally, a limiting post is formed on a side of the mounting bracket close to the connecting portion, and the limiting post is used for cooperating with a limiting blind hole on the mounting groove so that there can be a gap between the connecting portion and the wall of the mounting groove after the limiting post is inserted into the limiting blind hole; or,

[0019] A limiting blind hole is formed on a side of the mounting bracket close to the connecting portion, and the limiting blind hole is used for cooperating with a limiting post on the mounting groove so that there can be a gap between the connecting portion and the wall of the mounting groove after the limiting post is inserted into the limiting blind hole.

[0020] Optionally, the mounting bracket includes a bracket body and a pushing guide portion. The mounting boss and the first avoiding groove are formed on the bracket body. The pushing guide portion is formed on a side of the bracket body away from the mounting boss. A surface of the pushing guide portion away from the bracket body includes a guiding inclined surface and a resisting top surface. The resisting top surface is configured to abut against a wall of the mounting groove.

Another example is that when the user slides and presses the button at the same time, the pressure sensing module can detect the change in pressure and trigger the electronic device to increase or decrease the volume.

Detailed implementation manners

[0039] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and interpreting the present disclosure, and are not used to limit the present disclosure.

[0040] In the present disclosure, unless otherwise stated, the orientation terms such as "upper" and "lower" are generally defined in terms of the drawing direction of the corresponding drawings, and can be specifically referred to Figure 1 as shown, and "inner" and "outer" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have sequence and importance.

[0041] As Figures 1 to 7 shown, according to one aspect of the present disclosure, a button assembly is provided, including a button 10, a pressure detection component, and an elastic part 30. The button 10 is movably mounted on the housing 40 of the electronic device. The pressure detection component includes a flexible circuit board 21 and a pressure sensing module. The flexible circuit board 21 includes a pressure sensing part 211, and the pressure sensing module is disposed on the pressure sensing part 211. The button 10 can deform the pressure sensing part 211 under an external force, so that the pressure sensing module can detect the pressure. The elastic part 30 is configured to reset the flexible circuit board 21 and the button 10.

[0042] Through the above technical solution, since the button 10 is movably mounted on the housing 40 of the electronic device, the user can quickly and accurately find the position of the button 10, and by applying pressure to the button 10, the pressure sensing part 211 of the flexible circuit board 21 is deformed. Since the pressure sensing module is disposed on the pressure sensing part 211, the pressure sensing module can detect the pressure when the pressure sensing part 211 is deformed, thereby converting the pressure applied by the user to the button 10 into an electrical signal to trigger the corresponding function of the electronic device. When the user stops applying pressure to the button 10, the elastic part 30 can reset the flexible circuit board 21 and the button 10.

[0043] Compared with the related art in which the button assembly adopts the method of using a DOME sheet, the button assembly provided by the present invention can detect the slight deformation of the pressure sensing part 211 through the pressure sensing module, and has higher sensitivity. That is to say, the user can make the pressure sensing module detect the pressure by lightly pressing the button 10, thereby triggering the corresponding function of the electronic device and improving the user experience.

[0044] In addition, the user can also trigger different functions of the electronic device by applying different pressures on the button 10. For example, when the user applies a first pressure to the button 10, the pressure sensing module can detect the first pressure and trigger the electronic device to light up the screen. When the user applies a second pressure greater than the first pressure to the button 10, the pressure sensing module can detect the second pressure and trigger the electronic device to shut down or restart. For another example, when the user presses the button 10 while sliding, the pressure sensing module can detect the change in pressure and trigger the electronic device to increase or decrease the volume.

[0045] It should be noted that the present disclosure does not limit the specific installation position of the button 10 on the housing 40 of the electronic device. The button 10 can be installed on the middle frame, the front cover, or the back cover. In addition, the button 10 of the present disclosure can be a volume button, or a power button, etc., which is not limited in the present disclosure.

[0046] In order to enable the button 10 to deform the pressure sensing portion 211 under the action of an external force, and the elastic member 30 to reset the flexible circuit board 21 and the button 10, as an embodiment, Figure 1 As shown, the button 10 can abut against the elastic member 30, and the pressure sensing portion 211 can overlap the elastic member 30. With such a configuration, on the one hand, the button 10 can deform the elastic member 30 under the action of an external force, and since the pressure sensing portion 211 overlaps the elastic member 30, the deformation of the elastic member 30 can drive the pressure sensing portion 211 to deform, and when the external force on the button 10 disappears, the elastic member 30 can restore the deformation and push the button 10 to reset and drive the pressure sensing portion 211 to reset; on the other hand, since the button 10 abuts against the elastic member 30, it can be avoided that the button 10 directly acts on the pressure sensing portion 211 and causes damage to the flexible circuit board 21.

[0047] As another implementation, the button 10 may be directly connected to the pressure sensing portion 211 , and one end of the elastic member 30 may be connected to the housing 40 of the electronic device, and the other end may be connected to the button 10 .

[0048] Alternatively, if Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown, the button assembly also includes a mounting bracket 50, which is used to be inserted into the mounting groove 41 on the housing 40 and has an interference fit with the mounting groove 41. A mounting boss 51 and a first avoidance groove 52 adjacent to the mounting boss 51 are formed on the mounting bracket 50. The elastic member 30 is a spring sheet, which includes a fixed portion 31 and a deformation portion 32. The fixed portion 31 is fixed on the mounting boss 51, the button 10 is against the deformation portion 32, the pressure sensing portion 211 overlaps the deformation portion 32, and the first avoidance groove 52 is located on the side of the deformation portion 32 away from the button 10. Since the fixing portion 31 is fixed on the mounting boss 51 and the mounting bracket 50 is located in the mounting groove 41, the first avoidance groove 52 of the mounting bracket 50 is located on the side of the deformation portion 32 away from the button 10, and the first avoidance groove 52 is adjacent to the mounting boss 51. Therefore, the user can apply pressure to the button 10, and the button 10 pushes against the deformation portion 32 to cause deformation into the first avoidance groove 52. When the user stops applying pressure to the button 10, the spring piece returns to its original state and pushes against the button 10 to reset.

[0049] When assembling the key assembly, the staff can first fix the fixing portion 31 of the spring sheet on the mounting boss 51 of the mounting bracket 50, and then insert the mounting bracket 50 into the mounting groove 41. The mounting bracket 50 can be fixed in the mounting groove 41 through the interference fit between the mounting bracket 50 and the mounting groove 41. Since the first avoidance groove 52 is located on the side of the deformation portion 32 away from the key 10, the mounting bracket 50 can not only realize the installation of the spring sheet in the housing 40 of the electronic device, but also will not affect the deformation of the spring sheet.

[0050] It is understandable that, since the pressure sensing portion 211 is overlapped on the elastic member 30 , the flexible circuit board 21 can be installed in the installation groove 41 together with the installation bracket 50 .

[0051] In other embodiments, the mounting bracket 50 can also be connected to the mounting slot 41 by a fastener, so that the mounting bracket 50 is fixed in the mounting slot 41. In addition, the elastic member 30 can also be a spring, one end of the spring abuts against the button 10, and the other end of the spring is connected to the mounting bracket 50 or the slot wall of the mounting slot 41.

[0052] In order to reduce the risk of the fixing portion 31 being separated from the mounting boss 51 during use, as an embodiment, the fixing portion 31 can be optionally sandwiched between the mounting boss 51 and the groove wall of the mounting groove 41. Since the groove wall of the mounting groove 41 can push the fixing portion 31 against the mounting boss 51, the fixing force of the fixing portion 31 on the mounting boss 51 is improved, thereby reducing the risk of the fixing portion 31 and the mounting boss 51 being separated from the mounting boss 51 due to failure of the connection point between the fixing portion 31 and the mounting boss 51 during use.

[0053] In order to facilitate the user to install the spring piece in the correct position on the mounting bracket 50, as an implementation method,Figure 3 and Figure 4 As shown in Figure 4 , a positioning post 511 is formed on one of the mounting boss 51 and the fixing part 31, and a positioning hole 311 is formed on the other of the mounting boss 51 and the fixing part 31. The positioning hole 311 is for the positioning post 511 to pass through. Two opposite limiting protrusions 512 are further formed on the mounting boss 51, and the fixing part 31 is located between the two limiting protrusions 512.

[0054] The user can first align the positioning hole 311 with the positioning post 511, and then relatively move the mounting bracket 50 and the elastic piece. When the positioning post 511 passes through the positioning hole 311, the fixing part 31 of the elastic piece is located between the two limiting protrusions 512, and the positioning of the elastic piece on the mounting bracket 50 can be completed, so that it is convenient for the staff to manually or through an automated device to install the elastic piece at the correct position on the mounting bracket 50. The two limiting protrusions 512 can prevent the elastic piece from rotating around the positioning post 511.

[0055] Here, the cross-section of the positioning post 511 and the positioning hole 311 can be configured in any shape such as circular, rectangular, etc., as long as its outer peripheral surface can abut against the positioning hole 311 to prevent the positioning hole 311 from moving significantly along the radial direction of the positioning post 511. The present disclosure does not limit this. Further, when the cross-section of the positioning post 511 and the positioning hole 311 are configured as circular, it is beneficial to improve the positioning accuracy of the elastic piece on the mounting bracket 50.

[0056] In order to fix the fixing part 31 on the mounting boss 51, as an implementation manner, as Figure 3 shown, the fixing part 31 can be adhered to the mounting boss 51 through an adhesive layer 60. As another implementation manner, the fixing part 31 can also be connected to the mounting boss 51 through a fastener.

[0057] In order to enable the electronic device to trigger corresponding functions when the pressure sensing module detects pressure, as an implementation manner, as Figure 4 and Figure 5 shown, the flexible circuit board 21 further includes a connecting part 212 and an external connecting part 213. The connecting part 212 is connected between the pressure sensing part 211 and the external connecting part 213, and one end of the external connecting part 213 away from the connecting part 212 can extend out of the housing 40 from the notch of the mounting groove 41.

[0058] Since the connecting portion 212 is connected between the pressure sensing portion 211 and the external connection portion 213, and one end of the external connection portion 213 away from the connecting portion 212 can extend out of the housing 40 from the notch of the installation groove 41, the flexible circuit board 21 can be electrically connected to the circuit board of the electronic device through the external connection portion 213. The electrical signal of the pressure sensing portion 211 can be transmitted to the external connection portion 213 through the connecting portion 212 and then transmitted to the circuit board of the electronic device through the external connection portion 213, so that the electronic device can trigger corresponding functions when the pressure sensing module detects pressure.

[0059] To avoid damaging the flexible circuit board 21 during the process of inserting the mounting bracket 50 into the installation groove 41, as an implementation manner, as Figure 4 , Figure 5 and Figure 6 shown, the mounting bracket 50 has a pushing operation surface 54 for the user to push the mounting bracket 50 into the installation groove 41. The connecting portion 212 is arranged on the side of the mounting bracket 50 away from the pushing operation surface 54. The mounting bracket 50 is located between the pressure sensing portion 211 and the external connection portion 213. A second avoidance groove 53 is further formed on the mounting bracket 50 for the external connection portion 213 to pass through.

[0060] Since the mounting bracket 50 has a pushing operation surface 54 for the user to push the mounting bracket 50 into the installation groove 41 and the connecting portion 212 is arranged on the side of the mounting bracket 50 away from the pushing operation surface 54, when the user pushes the mounting bracket 50 into the installation groove 41, the pushing force is avoided from being applied to the connecting portion 212, thus preventing damage to the flexible circuit board 21. In addition, since a second avoidance groove 53 is further formed on the mounting bracket 50, the external connection portion 213 can pass through the gap between the mounting bracket 50 and the installation groove 41 from the second avoidance groove 53, avoiding damage to the external connection portion 213 caused by being squeezed by the mounting bracket 50 and the groove wall of the installation groove 41.

[0061] To reduce wear on the connecting kink between the connecting portion 212 and the external connection portion 213 by the mounting bracket 50, as an implementation manner, as Figure 5 shown, the mounting bracket 50 is formed with an avoidance notch 55 for avoiding the connecting kink between the connecting portion 212 and the external connection portion 213. By forming the avoidance notch 55 on the mounting bracket 50, the distance between the connecting kink between the connecting portion 212 and the external connection portion 213 and the corresponding position of the mounting bracket 50 can be increased, avoiding wear on the connecting kink between the connecting portion 212 and the external connection portion 213 by the mounting bracket 50, and thus reducing the possibility of damage to the flexible circuit board 21 caused by the mounting bracket 50.

[0062] As a specific implementation manner, as Figure 5As shown, the avoidance notch 55 can be an avoidance inclined surface 59 formed at the connection kink between the corresponding connection part 212 and the external connection part 213 of the mounting bracket 50. In other embodiments, the avoidance notch 55 can also be an arc-shaped groove or an L-shaped groove formed on the mounting bracket 50.

[0063] To avoid damage to the flexible circuit board 21 caused by the slot wall of the mounting slot 41 squeezing the connection part 212 after the mounting bracket 50 is pushed into the mounting slot 41, as an embodiment, as Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a limiting post 56 is formed on one side of the mounting bracket 50 close to the connection part 212. The limiting post 56 is used to cooperate with a limiting blind hole 42 on the mounting slot 41 so that there can be a gap 80 between the connection part 212 and the slot wall of the mounting slot 41 after the limiting post 56 is inserted into the limiting blind hole 42. Or, a limiting blind hole 42 is formed on one side of the mounting bracket 50 close to the connection part 212. The limiting blind hole 42 is used to cooperate with the limiting post 56 on the mounting slot 41 so that there can be a gap 80 between the connection part 212 and the slot wall of the mounting slot 41 after the limiting post 56 is inserted into the limiting blind hole 42.

[0064] That is to say, during the process of inserting the mounting bracket 50 into the mounting slot 41, when the limiting post 56 is inserted into the limiting blind hole 42 and abuts against the limiting blind hole 42 and cannot move any further, it means that the mounting bracket 50 is installed in place. And at this time, there is a gap 80 between the connection part 212 and the slot wall of the mounting slot 41. The positioning of the mounting bracket 50 in the mounting slot 41 can be realized through the cooperation of the limiting post 56 and the limiting blind hole 42, ensuring that there is a gap 80 between one side of the mounting bracket 50 close to the connection part 212 and the slot wall of the mounting slot 41, so as to avoid the mounting bracket 50 and the slot wall of the mounting slot 41 squeezing the connection part 212.

[0065] To make it easier for the mounting bracket 50 to be inserted into the mounting slot 41 and have an interference fit with the mounting slot 41, as an embodiment, as Figure 5 shown, the mounting bracket 50 includes a bracket main body 57 and a pushing guiding part 58. The mounting boss 51 and the first avoidance groove 52 are formed on the bracket main body 57. The pushing guiding part 58 is formed on the side of the bracket main body 57 away from the mounting boss 51. The surface of the pushing guiding part 58 away from the bracket main body 57 includes a guiding inclined surface 581 and an abutting surface 582. The abutting surface 582 is used to abut against the slot wall of the mounting slot 41. The guiding inclined surface 581 extends obliquely from the surface of the bracket main body 57 close to the pushing guiding part 58 to the abutting surface 582.

[0066] Since the pushing guide portion 58 is formed on the side of the bracket body 57 away from the mounting boss 51, two opposite groove walls of the mounting groove 41 will respectively abut against the bracket body 57 and the abutting surface 582 of the pushing guide portion 58. Since the guiding inclined surface 581 extends obliquely from the surface of the bracket body 57 close to the pushing guide portion 58 to the abutting surface 582, during the process of inserting the mounting bracket 50 into the mounting groove 41, the guiding inclined surface 581 can guide the groove wall of the mounting groove 41 to the abutting surface 582, making it easier for the mounting bracket 50 to be inserted into the mounting groove 41.

[0067] Optionally, for the embodiment in which the second avoidance groove 53 is formed on the mounting bracket 50, it can be understood that the pushing guide portion 58 can be a protrusion adjacent to the second avoidance groove 53 formed after the second avoidance groove 53 is formed on the mounting bracket 50.

[0068] Optionally, the button 10 includes a button body 11 and a force transmission portion 12 connected to the button body 11. One end of the force transmission portion 12 away from the button body 11 can deform the pressure sensing portion 211 when an external force is applied to the button body 11. There are multiple force transmission portions 12, and the multiple force transmission portions 12 are arranged at intervals along the length direction of the button body 11. In this way, when the user presses at different positions of the button body 11, the pressure sensing portion 211 can be deformed through the force transmission portion 12. For example, the button 10 can be a volume button. When the user presses the upper end of the button body 11, the force transmission portion 12 located at the upper end of the button body 11 can deform the pressure sensing portion 211, so as to increase the volume. When the user presses the lower end of the button body 11, the force transmission portion 12 located at the lower end of the button body 11 can deform the pressure sensing portion 211, so as to decrease the volume.

[0069] Optionally, there are multiple pressure sensing portions 211, and a pressure sensing module is arranged on each sensing portion. The multiple force transmission portions 12 correspond to the multiple pressure sensing portions 211 one by one, and each pressure sensing portion 211 can be deformed under the action of its corresponding force transmission portion 12. Since both the force transmission portion 12 and the pressure sensing portion 211 are multiple, the multiple force transmission portions 12 are arranged at intervals along the length direction of the button body 11, a pressure sensing module is arranged on each sensing portion, and the multiple force transmission portions 12 correspond to the multiple pressure sensing portions 211 one by one, enabling the user to apply pressure to different positions of the button body 11 to deform the corresponding pressure sensing portion 211 and trigger the corresponding functions of the electronic device. Thus, designers can endow the button assembly with more functions, such as volume adjustment, quick photo taking, screenshot, etc., which is beneficial to improving the functionality of the button assembly.

[0070] As shown above, since the pressure detection component provided by the present disclosure has high detection sensitivity, as long as the pressure sensing part 211 deforms, the pressure sensing module can detect the pressure. Therefore, for the embodiment where the button 10 is a volume button, the user can not only adjust the volume by pressing down the button 10, but also adjust the volume by sliding and pressing (i.e., applying a certain pressure while sliding the finger on the button body 11). Specifically, when the user's finger slides upward on the button body 11, the force transmission part 12 located at the upper end of the button body 11 acts on the corresponding pressure sensing part 211, and the pressure sensing module on the pressure sensing part 211 senses the change in pressure to trigger the increase in the volume of the electronic device; when the user's finger slides downward on the button body 11, the force transmission part 12 located at the lower end of the button body 11 acts on the corresponding pressure sensing part 211, and the pressure sensing module on the pressure sensing part 211 senses the change in pressure to trigger the decrease in the volume of the electronic device. That is to say, by using the button assembly of the present disclosure, more ways to operate the button 10 can be provided for the user, improving the user experience.

[0071] Optionally, the force transmission part 12 can be columnar.

[0072] To prevent the button body 11 from detaching from the housing 40, as an implementation manner, optionally, the button body 11 is formed with a support leg 111, and the button assembly further includes a stop structure 70 for being installed on the housing 40. The stop structure 70 is arranged to be able to stop on the support leg 111 when the elastic member 30 moves the button 10 towards the outside of the housing 40. Since the support leg 111 is formed on the button body 11, when the user applies pressure to the button body 11, the button body 11 will drive the support leg 111 to move away from the stop structure 70. When the user stops applying pressure to the button body 11, under the action of the elastic member 30, the button body 11 will drive the support leg 111 to move towards the stop structure 70 until the stop structure 70 stops on the support leg 111, thereby preventing the button body 11 from detaching from the housing 40.

[0073] According to another aspect of the present disclosure, an electronic device is provided, including a housing 40 and the above-mentioned button assembly, and the button 10 of the button assembly is movably installed on the housing 40. Here, the electronic device can be a mobile phone, a computer, a radio, etc., as long as the user needs to interact with it to trigger corresponding functions, and the present disclosure does not limit this.

[0074] Optionally, the housing 40 can include a middle frame, and the button 10 is movably installed on the middle frame.
