DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] The present disclosure provides a button module, which includes a pressing part, a driving element and a transmission element, wherein the driving element performs linear driving according to a received signal; one end of the transmission element abuts against the pressing part, and the other end of the transmission element abuts against the driving element, and the force generated by the linear driving of the driving element is transmitted to the pressing part through the transmission element.

[0031] In the embodiments of the present disclosure, a transmission element is used to connect a driving element that can generate a linear drive with the power of the pressing part, so that the linear drive of the driving element produces a driving effect on the pressing part, and then the pressing part generates movement, forming feedback of the pressing part to the user's touch, so that the user can get clear feedback after touching the pressing part to determine whether the touch is successful.

[0032] The key module refers to a module having a pressing part 1 and being able to give feedback to the user's behavior of touching the pressing part 1; the electronic device refers to a device having the key module of the present disclosure, such as a mobile phone, a computer, a television, etc. When the electronic device is a mobile phone, the pressing part 1 of the key module can be a side key of the mobile phone. Of course, those skilled in the art can also set the pressing part 1 to a key of the keyboard of the mobile phone or a virtual key displayed on the screen as needed.

[0033] In some embodiments, the pressing portion 1 can be a solid-state button. The solid-state button itself does not need to generate mechanical action, but only needs to sense the change in charge to complete the sensing of the user's touch action. In this way, the user lacks feedback after the touch is recognized by the electronic device, making the user unable to determine whether an effective touch is performed on the electronic device.

[0034] Figure 1 is a structural diagram of a key module according to an exemplary embodiment. Figure 1 As shown, the key module includes a pressing portion 1 , a driving element 3 and a transmission element 2 .

[0035] The driving element 3 performs linear driving according to the received signal. One end of the transmission element 2 abuts against the pressing part 1 , and the other end of the transmission element 2 abuts against the driving element 3 . The force generated by the linear driving of the driving element 3 is transmitted to the pressing part 1 through the transmission element 2 .

[0036] In the embodiment of the present disclosure, a transmission element 2 is used to connect the driving element 3 that can generate linear drive to the pressing part 1, so that the linear drive of the driving element 3 produces a driving effect on the pressing part 1, and then the pressing part 1 is moved, forming feedback of the pressing part 1 to the user's touch, so that the user can get clear feedback after touching the pressing part 1 to determine whether the touch is successful.

[0037] In some embodiments, the pressing portion 1 is a solid-state button, and it is possible to determine whether the user has touched the pressing portion 1 through changes in charge.

[0038] In some embodiments, the current connected to the driving element 3 is alternating current, and the direction of the voltage connected to the driving element 3 continuously changes, so that the driving element 3 produces a continuous linear drive, thereby continuously driving the pressing part 1, and finally forming a vibration effect on the pressing part 1, which lasts for a longer time and the feedback obtained by the user is clearer.

[0039] In some embodiments, the driving element 3 may be a piezoelectric element. When the piezoelectric element is connected to a power source, the piezoelectric element can generate telescopic motion. By changing the direction of the two poles of the power source, the piezoelectric element can generate continuous telescopic motion.

[0040] In some embodiments, the piezoelectric element can be made by stacking several piezoelectric films. When the piezoelectric film is connected to a voltage, its own deformation will be directly reflected as vibration, but the piezoelectric film is too thin and easily damaged. After stacking several piezoelectric films to form a piezoelectric element with a certain thickness, when the piezoelectric element is connected to a voltage, the deformation of the piezoelectric element will be reflected as elongation and shortening, thereby making the piezoelectric element a power source with linear driving capability.

[0041] In some embodiments, the piezoelectric element is connected to a power source, and its linear driving direction is perpendicular to the flow direction of the current. Therefore, the piezoelectric element should be connected to a current perpendicular to the extension direction of the piezoelectric element, that is, the connection direction of the two poles of the power source is perpendicular to the extension direction of the piezoelectric element.

[0042] Figure 2 is a structural diagram of a key module according to an exemplary embodiment. Figure 3 yes Figure 2 The enlarged view of point A in the middle. Figure 4 is a structural diagram of a key module according to an exemplary embodiment. Figures 1 to 4 As shown, in some embodiments, the key module includes a middle frame 5, the pressing portion 1 is located in the middle frame 5, and the transmission element 2 includes a fixing portion 23 and a transmission portion.

[0043] The fixing part 23 is rotationally connected to the middle frame 5 ; the transmission part is connected to the fixing part 23 , and the transmission part is connected to the middle frame 5 through the fixing part 23 , one end of the transmission part abuts against the pressing part 1 , and the other end of the transmission element 2 abuts against the driving element 3 .

[0044] In the embodiment of the present disclosure, the transmission element 2 forms a lever structure with the fixed part 23 as the fulcrum and the transmission part as the lever arm. Power is transmitted through this lever structure, and the power output can be adjusted by the relative length of the lever arm.

[0045] In some embodiments, the transmission portion includes a first transmission arm 21 and a second transmission arm 22, the first transmission arm 21 extends from the fixed portion 23 to the driving element 3, and the first transmission arm 21 abuts against the driving element 3; the second transmission arm 22 extends from the fixed portion 23 to the pressing portion 1, and the second transmission arm 22 abuts against the pressing portion 1; the fixed portion 23 avoids the linear driving path of the driving element 3, and the length of the first transmission arm 21 is less than the length of the second transmission arm 22.

[0046] In an embodiment of the present disclosure, the transmission element 2 includes a lever structure with a first transmission arm 21 as a power arm, a second transmission arm 22 as a resistance arm, and a fixed part 23 as a fulcrum. By setting the length of the first transmission arm 21 to be smaller than the length of the second transmission arm 22, the force arm length of the power arm is smaller than the force arm length of the resistance arm, and the linear driving amplitude generated by the driving element 3 is amplified, so that the second transmission arm 22 can output a larger stroke drive to the pressing part 1, so that the vibration amplitude of the pressing part 1 is larger, and the user's tactile feeling is more obvious, thereby overcoming the problem that the linear driving amplitude of the driving element 3 is too small and the user's feeling is not obvious.

[0047] like Figure 2 , Figure 4 As shown, in some embodiments, the linear driving direction of the driving element 3 is arranged along the extension direction of the middle frame 5, and the extension directions of the first transmission arm 21 and the second transmission arm 22 are arranged to cross each other.

[0048] In the embodiment of the present disclosure, the extension directions of the first transmission arm 21 and the second transmission arm 22 are cross-arranged, so that the directions of the power input and output of the transmission element 2 can be different, so that the linear driving direction of the driving element 3 does not have to be consistent with the driving direction of the pressing part 1, making the setting method of the driving element 3 more flexible.

[0049] In order to make the pressing part 1 generate an amplitude that can be clearly perceived by the user, the driving element 3 needs to generate a sufficient linear driving amplitude, and for this purpose, the driving element 3 needs to have a sufficient linear driving length. The linear driving direction of the driving element 3 is set to be the same as the extension direction of the middle frame 5, which can effectively utilize the space near the middle frame 5 and reduce the space occupied in the thickness direction of the frame.

[0050] In some embodiments, the button module is applied to a mobile phone, and the mobile phone screen is set on the inner side of the middle frame 5. The linear driving direction of the driving element 3 is set to be the same as the extension direction of the middle frame 5, which can minimize the impact of the driving element 3 on the screen and increase the screen-to-body ratio.

[0051] like Figure 4 As shown, in some embodiments, the extension directions of the first transmission arm 21 and the second transmission arm 22 are perpendicular.

[0052] In order to maximize the driving effect of the transmission element 2 on the pressing portion 1, it is necessary to make the driving direction of the transmission element 2 on the pressing portion 1 perpendicular to the plane of the pressing portion 1. Generally speaking, the plane of the pressing portion 1 is parallel to the plane of the side wall of the middle frame 5. When the linear driving direction of the driving element 3 is consistent with the extension direction of the middle frame 5, the linear driving direction of the driving element 3 is also parallel to the plane of the pressing portion 1. Through the mutually perpendicular first transmission arm 21 and second transmission arm 22, the driving force generated by the driving element 3 parallel to the plane of the pressing portion 1 can be effectively converted into a driving force perpendicular to the plane of the pressing portion 1.

[0053] like Figure 1 , Figure 4 As shown, in some embodiments, the first transmission arm 21 includes a first contact surface 211 in contact with the driving element 3, and the driving element 3 includes a second contact surface 31 in contact with the first transmission arm 21, and the first contact surface 211 and the second contact surface 31 are set to be tangent arc surfaces.

[0054] The first transmission arm 21 is driven by the driving element 3 to perform a circular motion around the fixing portion 23 , which results in that the contact surface between the first transmission arm 21 and the driving element 3 is not fixed but changes with the rotation of the first transmission arm 21 .

[0055] In this embodiment, the first contact surface 211 and the second contact surface 31 are set to be tangent arcs, so that the contact between the driving element 3 and the first transmission arm 21 always remains smooth when driving the first transmission arm 21, avoiding severe friction between the driving element 3 and the first transmission arm 21 during high-frequency linear driving, and making the cooperation between the driving element 3 and the first transmission arm 21 smoother.

[0056] like Figure 4 As shown, in some embodiments, the first transmission arm 21 includes an “L”-shaped bending portion, one end of the “L”-shaped bending portion is connected to the fixing portion 23 , and the other end extends toward the driving element 3 .

[0057] When the driving element 3 performs linear driving, it will generate continuous and high-frequency impact on the first transmission arm 21, which may easily cause deformation of the first transmission arm 21. If the deformation is serious, the first transmission arm 21 may even lose contact with the driving element 3, causing transmission failure.

[0058] The side of the first transmission arm 21 close to the driving element 3 is set to be an “L”-shaped bend, so that the deformation resistance of the first transmission arm 21 can be increased through the bending, thereby preventing the first transmission arm 21 from deforming and failing.

[0059] like Figure 4 As shown, in some embodiments, the driving element 3 is disposed between the pressing portion 1 and the transmission element 2 .

[0060] In the embodiment of the present disclosure, the driving element 3 is arranged at a position close to the pressing part 1, so that the vibration energy generated by the driving element 3 itself in addition to the linear drive can directly act on the pressing part 1 to enhance the vibration effect of the pressing part 1, and it can also be kept as far away as possible from other components arranged in the middle frame 5, such as a screen or a motherboard, to avoid negative effects on other components in the middle frame 5.

[0061] Figure 5 is a schematic diagram of a transmission element according to an exemplary embodiment. Figure 1 , Figure 5 As shown, in some embodiments, the pressing portion 1 includes a striking seat 11 extending toward the interior of the middle frame 5, the striking seat 11 is arranged to avoid the driving element 3, the second transmission arm 22 includes a first segment 221 and a second segment 222, the first segment 221 is vertically connected to the fixing portion 23, one end of the second segment 222 is connected to the first segment 221, and the other end of the second segment 222 extends toward the striking seat 11, and the second segment 222 protrudes toward one side of the striking seat 11 to form a columnar structure with an arc surface.

[0062] The first transmission arm 21 and the first segment 221 of the second transmission arm 22 of the transmission element 2 bear torque in the same plane, while the second segment 222 extends beyond the plane where the first transmission arm 21 and the first segment 221 are located, and needs to bear torque centered on the first segment 221, causing the second segment 222 to be easily deformed and damaged.

[0063] In the embodiment of the present disclosure, the second segment 222 is thickened, which can effectively enhance the anti-torsion capability of the second segment 222 and prevent the second segment 222 from being deformed and damaged.

[0064] like Figure 1 , Figure 5 As shown, in some embodiments, the striking seat 11 avoids the driving element 3 in a direction perpendicular to the extension direction of the driving element 3 , the first segment 221 is arranged parallel to the driving element 3 , and the second segment 222 is arranged perpendicular to the first segment 221 .

[0065] In this embodiment, the first segment 221 and the second segment 222 are vertically arranged to make the mechanical structure of the first segment 221 and the second segment 222 simpler, thereby reducing the possibility of damage to the first segment 221 and the second segment 222.

[0066] like Figures 2 to 4 As shown, in some embodiments, the middle frame 5 includes a first mounting hole 51 and a second mounting hole 52. The first mounting hole 51 passes through the outer surface 55 of the middle frame 5 and is used to install the pressing part 1 on the middle frame 5 from the inside to the outside; the second mounting hole 52 passes through the first mounting hole 51 from the side surface 53 of the middle frame and is used to install the driving element 3 and the transmission element 2 on the middle frame 5.

[0067] In the embodiment of the present disclosure, the pressing portion 1, the driving element 3 and the transmission element 2 are all arranged in the middle frame 5, so as to avoid occupying the inner space of the middle frame 5 and provide more space for other elements inside the middle frame.

[0068] In some embodiments, the opening of the first mounting hole 51 on the outer surface 55 of the middle frame 5 is smaller than the opening on the inner surface 54 of the middle frame 5, and the pressing portion 1 enters from the opening of the first mounting hole 51 on the inner surface 54 of the middle frame 5, and partially protrudes from the opening of the outer surface 55 of the middle frame 5 to the outer surface 55 of the middle frame 5, and the protruding portion is used for user touch. The pressing portion 1 includes a fixing seat 12 arranged at both ends of the extension direction, and the fixing seat 12 abuts against the inner wall of the first mounting hole 51 to limit the maximum range of the pressing portion 1 protruding from the first mounting hole 51.

[0069] In some embodiments, a second mounting hole 52 connected to the first mounting hole 51 is formed on the side surface 53 of the middle frame, the driving element 3 and the transmission element 2 are arranged in the second mounting hole 52, and the pressing portion 1 is arranged between the driving element 3 and the transmission element 2 and the outer surface 55 of the middle frame 5. The driving element 3 and the transmission element 2 limit the pressing portion 1 to prevent the pressing portion 1 from falling off from the first mounting hole 51.

[0070] In some embodiments, the button module includes a fixing component 6 , and a mounting groove for accommodating the fixing component 6 is opened on the middle frame 5 , and a part of the mounting groove is connected to the first mounting hole 51 .

[0071] The fixing assembly 6 includes a fixing pin 61 inserted in the mounting groove and an elastic piece 62 fixedly connected to the fixing pin 61 and extending from the mounting groove to the first mounting hole 51. The fixing seat 12 is provided with a fixing groove 13 for inserting the elastic piece 62, which is used to fix the pressing part 1 and reset the pressing part 1 pressed by the user by using the elasticity of the elastic member itself.

[0072] In some embodiments, the button module may include a power supply circuit 4 , which extends from the inner side of the middle frame 5 into the first mounting hole 51 and is connected to the driving element 3 to supply power to the driving element 3 .

[0073] Figure 6 is a schematic diagram of an electronic device according to an exemplary embodiment. Figure 6 As shown, the present disclosure also provides an electronic device, including the key module of the present disclosure.

[0074] The electronic device disclosed in the present invention is a device having a pressing portion 1 and requiring feedback on the user's behavior of touching the pressing portion 1, such as a mobile phone, a tablet computer, a laptop computer, a display, etc. When the electronic device is a mobile phone, the pressing portion 1 of the key module can be either a side key of the mobile phone or a key of a keyboard.

[0075] In an embodiment of the present disclosure, by setting the button module of the present disclosure in an electronic device, when the pressing part 1 in the button module uses a solid-state pressing part 1, the driving element 3 and the transmission element 2 can also provide vibration for the pressing part 1, thereby providing feedback on the user's touching the pressing part 1, so that the user can clearly know whether the touch behavior is detected by the electronic device.

[0076] Figure 6 The electronic device is exemplarily shown as a mobile phone, but it should be noted that the electronic device in the present disclosure is not limited to a mobile phone, and those skilled in the art can apply the key module of the present disclosure to other electronic devices, and the present disclosure does not limit this.

[0077] In some embodiments, the electronic device includes a mainboard for controlling the electronic device, and the key module includes a power supply circuit 4 for connecting the driving element 3 to the mainboard. The pressing portion 1 is a solid-state key and is electrically connected to the mainboard.

[0078] In the embodiment of the present disclosure, when the pressing part 1 is touched by the user, the change in charge will cause the on and off state of the pressing part 1 to change, which will then be detected by the mainboard, thereby determining that the user has touched the pressing part 1. The mainboard then supplies power to the power supply circuit 4 connected to the driving element 3, causing the driving element 3 to generate linear drive, and ultimately causing the pressing part 1 to vibrate, thereby providing feedback to the user.

[0079] In some embodiments, in order to achieve different vibration intensities, the mainboard can change the power supply intensity to the power supply circuit 4 to adjust the vibration intensity of the pressing part 1 .
