[0027] See also Figure 1 , Figure 1 It is a structural schematic diagram of an exploded view of a push button assembly provided in the present application.
[0028] The present application provides a push button assembly. Figure 1 and Figure 2As shown, the push button assembly of this embodiment includes a shell 10, a push button 20, an elastic structure 40 and a pressure membrane 30. The shell 10 is formed with an accommodating space 103, and a first opening 1011 is formed on the shell 10 to expose the accommodating space 103. The push button 20 is arranged in the accommodating space 103, and at least part of the push button 20 is exposed to the first opening 1011. The push button 20 is movably connected to the shell 10 so as to be able to move in the accommodating space 103. The elastic structure 40 is arranged in the shell 10. The pressure membrane 30 is arranged in the shell 10, and the elastic structure 40 is located between the push button 20 and the pressure membrane 30. The pressure membrane 30 is arranged corresponding to the elastic structure 40. When the push button 20 moves to different positions, the elastic structure 40 generates different pressures on the pressure membrane 30.
[0029] In an optional embodiment, a housing space 103 is provided in the housing 10, and the push button 20 can be installed in the housing space 103, and a first opening 1011 connected to the housing space 103 is provided on the housing 10, and the push button 20 can be movably connected in the first opening 1011, and the push button 20 is partially exposed in the first opening 1011, and the push button 20 can be pushed to slide in the first opening 1011, and the push button 20 moves in a direction perpendicular to the axis direction of the first opening 1011, and the pressure membrane 30 is moved when the push button 20 is located at different positions of the first opening 1011. When the push button 20 is in the position, the pressure membrane 30 can accept the different pressures brought by the push button 20 squeezing the elastic structure 40, wherein a boss structure (not shown) is provided on the side of the push button 20 close to the pressure membrane 30, and the elastic structure 40 can be squeezed by the boss structure to squeeze the pressure membrane 30, and the two ends of the first opening 1011 can limit the push button 20. The length of the first opening 1011 can be determined according to the pressure received by the pressure membrane 30, so that pushing the push button 20 can make the pressure membrane 30 reach the resistance value of the predetermined circuit on-off threshold, and can also be set as needed, and the present application does not make specific limitations here.
[0030] Furthermore, if Figure 2 and Figure 4As shown, when the push button 20 moves to different positions in a direction perpendicular to the axial direction of the first opening 1011, the pressure membrane 30 can receive different pressures caused by the push button 20 squeezing the elastic structure 40. The impedance RL of the pressure membrane 30 changes according to the size of the squeezing force. The pressure membrane 30 is connected to an external circuit and uses the ADC port (analog / digital conversion interface) of the MCU (microcontroller unit) to detect the pressure drop UL on the impedance RL of the pressure membrane 30. Since the push button 20 moves in a direction perpendicular to the axial direction of the first opening 1011, the pressure membrane 30 can receive the size of the pressure caused by the push button 20 squeezing the elastic structure 40. The impedance RL of the pressure membrane 30 will change continuously according to the size of the pressure. The different sizes of the squeezing forces on the pressure membrane 30 caused by different strokes of the push button 20 can be used. The ADC port of the MCU can receive different RL values of the pressure membrane 30, and the displacement of the push button 20 can be known based on the position information of the push button 20. Among them, Figure 4 As shown, under the condition of known resistance R and power supply voltage VCC, the voltage drop formula of the line is as follows: RL = UL*R / (VCC-UL).
[0031] In this embodiment, during the production of the push button 20 or the pressure membrane 30, production errors may occur. When the push button 20 is pushed in a direction perpendicular to the axis direction of the first opening 1011, the purpose of opening the external component needs to be achieved. The pressure membrane 30 can adjust its own resistance value according to the pressure transmitted by the push button 20 squeezing the elastic structure 40, that is, the impedance RL of the pressure membrane 30 changes continuously according to the pressure. Since the pressure on the pressure membrane is a process of continuous increase or decrease, the displacement of the push button 20 can be larger or smaller, so that the pressure value received by the pressure membrane 30 is larger or smaller, thereby realizing the dynamic adjustment of the threshold of the line on and off triggered by the push button 20, avoiding the failure of the push button 20 or the unstable function caused by the production error. Further, the change of the push button 20 toggle stroke causes the dynamic change of the resistance value of the pressure membrane 30, thereby causing the dynamic change of the line voltage drop. Based on this change mode, the displacement change of the push button 20 can be converted into the line voltage drop change, and then it is easy to adjust the push button 20 to a specific position and then control the on and off of the push button switch, which can effectively increase the versatility of the product.
[0032] Through the above method, by pushing the push button 20 to move in a direction perpendicular to the axial direction of the first opening 1011, the pressure membrane 30 can accept the different pressures brought by the push button 20 squeezing the elastic structure 40 when the push button 20 is located at different positions of the first opening 1011. On the one hand, the pressure membrane 30 can adjust its own resistance value according to the size of the pressure transmitted by the elastic structure 40, thereby realizing the dynamic adjustment of the on-off threshold of the line triggered by the push button 20 without causing false touches; on the other hand, the displacement change of the push button 20 can be converted into a line voltage drop change, thereby realizing the adjustment of the push button 20 to a specific position and then controlling the on-off of the line, which effectively increases the versatility of the product.
[0033] In an optional embodiment, along the moving direction of the push button 20, the thickness of the push button 20 and / or the elastic structure 40 in the direction from the push button 20 to the pressure membrane 30 is set to be variable. That is, in order to facilitate the user to push the push button 20 to drive the elastic structure 40 to squeeze the pressure membrane 30, thereby achieving the purpose of opening the external component. In this embodiment, the thickness of the push button 20 in the direction from the push button 20 to the pressure membrane 30 is set to be variable. That is, a boss structure can be set on the end of the push button 20 close to the elastic structure 40. When the push button 20 is pushed, the boss structure can squeeze the elastic structure 40, so that the elastic structure 40 squeezes the pressure membrane 30, wherein the boss structure can adopt a wedge-shaped structure with a thickness gradually thickened or thinned in the direction perpendicular to the axis direction of the first opening 1011, and the elastic structure 40 can be squeezed by the boss structure of the push button 20, so that the elastic structure 40 squeezes the pressure membrane, thereby opening the external component. In another embodiment, the thickness of the elastic structure 40 in the direction from the push button to the pressure membrane 30 is gradually changed. The elastic structure 40 can be set as a wedge-shaped structure, that is, when the push button 20 is pushed, the push button 20 can squeeze the elastic structure 40 of the wedge-shaped structure, so that the elastic structure 40 squeezes the pressure membrane 30 according to the movement of the push button 20, thereby opening the external component. Among them, the thickness of the push button 20 and the elastic structure in the direction from the push button 20 to the pressure membrane 30 can also be set to be changed, so that when the user pushes the push button 20, the elastic structure 40 squeezes the pressure membrane 30 to achieve the purpose of opening the external component. Among them, the push button 20 and the elastic structure 40 can adopt a wedge-shaped structure to facilitate squeezing the pressure membrane 30, and other structures can also be adopted, which is not specifically limited in this application. Furthermore, the location where the push button 20 is thicker is a boss structure facing the pressure membrane 30, and the location where the elastic structure 40 is thicker can be a raised structure facing the pressure membrane 30 or a raised structure facing the push button 20. The present application does not make specific limitations here. The two side edges of the above-mentioned raised structure in the moving direction of the push button 20 are gradually thickened or thinned to ensure that the push button 20 and the elastic structure 40 will not be stuck.
[0034] In an optional embodiment, the pressure membrane 30 is arranged at a certain angle with the moving direction of the push button 20, so that the elastic structure 40 is squeezed to give different pressures to the pressure membrane 30 during the movement of the push button 20. The pressure membrane 30 is arranged obliquely inside the housing 10, that is, the pressure membrane 30 is arranged obliquely inside the housing 10, so that the push button 20 drives the elastic structure 40 to move, so that the push button 20 drives the elastic structure 40 to squeeze the pressure membrane 30, so that the pressure membrane 30 receives different pressures given by the elastic structure 40, wherein the angle between the pressure membrane 30 and the moving direction of the push button 20 is set to be less than 90°, for example, 0°, 30°, 45°, etc., and the present application does not make specific limitations here.
[0035] In an optional embodiment, the resistance value of the pressure membrane 30 changes in different pressure ranges to control the external components to achieve different terminal functions. Therefore, the pressure membrane 30 can adjust its own resistance value according to the pressure transmitted by the push button 20 squeezing the elastic structure 40, that is, the impedance RL of the pressure membrane 30 changes continuously according to the pressure. The change in the push button 20 toggle stroke causes a dynamic change in the resistance value of the pressure membrane 30, that is, the pressure membrane 30 changes its own resistance value according to the different pressures given by the elastic structure 40, thereby causing a dynamic change in the line voltage drop, that is, the displacement change of the push button can be converted into a change in the line voltage drop, so as to achieve the control of the on and off of the push button switch when the push button 20 is adjusted to enable the external components to achieve different terminal functions.
[0036] In an optional embodiment, if Figure 3 As shown, the housing 10 includes a first housing 101 and a second housing 102, and the first housing 101 and the second housing 102 are detachably connected to form an accommodating space 103. Therefore, the first housing 101 is buckled on the second housing 102 to form an accommodating space 103, and the push button 20 can be set in the accommodating space 103. Further, the push button 20 is slidably connected to the first housing 101 and / or the second housing 102, so that the push button 20 can move in the accommodating space 103. Therefore, the push button 20 can be slidably connected to the first housing 101, or can be slidably connected to the second housing 102, or the push button 20 is slidably connected to the first housing 101 and the second housing 102, and the present application does not make specific restrictions here. And the push button 20 is at least partially located outside the first housing 101, and can push the push button 20 to move in the accommodating space 103. Since the pressure membrane 30 is arranged in the second housing 102 corresponding to the push button 20, the pressure membrane 30 can receive different pressures according to the movement of the push button 20.
[0037] In an optional embodiment, the second shell 102 is provided with a second opening 1021 corresponding to the push button 20, and the elastic structure 40 is movably connected to the second opening 1021. Alternatively, the elastic structure 40 is located in the second opening 1021, and is clamped by the push button 20 and the pressure membrane 30 or is connected to the pressure membrane 30. Therefore, by providing the second opening 1021 in the second shell 102, the elastic structure 40 can be fixedly set inside the second opening 1021, or the elastic structure 40 can be movably set inside the second opening 1021 and clamped by the push button 20 and the pressure membrane 30, or the elastic structure 40 can be connected to the pressure membrane 30. Other convenient installation methods can also be used, and the present application does not make specific restrictions here. Figure 1 As shown, the elastic structure 40 is arranged between the push button 20 and the pressure membrane 30. When the push button 20 is pushed to move in a direction perpendicular to the axial direction of the first opening 1011, the push button 20 can press the elastic structure 40, so that the elastic structure 40 squeezes the pressure membrane 30, and the pressure membrane 30 can receive the different pressures brought by the push button 20 squeezing the elastic structure 40.
[0038] Furthermore, if Figure 1 and Figure 2 As shown, the elastic structure 40 includes an elastic contact 401, and the thickness of the elastic contact 401 in the direction from the push button 20 to the pressure membrane 30 is set to be variable, so that the elastic contact 401 can give different pressures to the pressure membrane 30 during the movement of the push button 20. That is, the elastic contact 401 is set on the elastic structure 40, and when the push button 20 is pushed to move in the vertical direction of the axis direction of the first opening 1011, since the thickness of the elastic contact 401 in the direction from the push button 20 to the pressure membrane 30 is set to be variable, that is, the thickness of the elastic contact 401 gradually thickens or thins, the push button 20 can squeeze the elastic contact 401 to squeeze or separate from the pressure membrane 30. When the push button 20 is pushed to slide in the direction of the first opening 1011 toward the thickening direction of the elastic contact 401, the elastic contact 401 can squeeze the pressure membrane 30 downward, that is, reach the circuit opening threshold to control the opening of the external component. When the external component needs to be closed, when the push button 20 is pushed in the first opening 1011 to slide in the direction of the thinning of the elastic contact 401, the elastic contact 401 can rebound upward, so that the elastic contact 401 is separated from the pressure membrane 30, that is, the line disconnection threshold is reached to control the external component to be closed.
[0039] In an optional embodiment, if Figure 1As shown, the elastic structure 40 is provided with a third opening 4011, and one end of the elastic contact 401 along the movement direction of the push button 20 is connected to the side wall of the third opening 4011. Therefore, the side wall of the elastic structure 40 is installed on the side wall of the second opening 1021, so as to fix the elastic structure 40. Since the third opening 4011 is provided on the elastic structure 40, the position of the third opening 4011 corresponds to the position of the first opening 1011, and the elastic contact 401 is installed on the side wall of the third opening 4011 in the sliding direction of the push button 20 in the first opening 1011, that is, the elastic contact 401 can move up and down in the third opening 4011 and in the axial direction of the third opening 4011, so that when the push button 20 is pushed to slide inside the first opening 1011, the push button 20 can push the elastic contact 401 to move up and down in the third opening 4011, so that the elastic contact 401 squeezes or separates from the pressure membrane 30, reaches the circuit on-off threshold, and thus opens or closes the external component.
[0040] In an optional embodiment, the first shell 101 is provided with a slide groove (not shown) at the edge forming the first opening 1011, the slide groove is communicated with the accommodating space 103, and the push button 20 is movably connected in the slide groove. That is, by providing the slide groove at the opening of the first opening 1011, the push button 20 can slide inside the slide groove, and the slide groove can prevent the push button 20 from popping out of the first shell 101 when the push button 20 slides in the first opening 1011, thereby limiting the push button 20 and preventing the push button 20 from popping out of the shell 10. Alternatively, in other embodiments, the push button 20 is provided with a slide groove, and the first shell 101 is located in the slide groove at the edge forming the first opening 1011, thereby realizing the sliding connection between the push button 20 and the first shell 101. Among them, a sliding block adapted to the slide groove may be provided on the side wall of the push button 20 to facilitate the push button 20 to slide in the first opening 1011. Other structures that facilitate the push button 20 to slide inside the slide groove may also be provided on the side wall of the push button 20, such as ball bearings, etc., which are not specifically limited in this application.
[0041] In an optional embodiment, if Figure 3As shown, the second housing 102 is provided with a slide 50 adapted to the edge of the accommodating space 103, and a through hole 501 is provided on the slide 50, and the push button 20 is movably connected with the elastic contact 401 through the through hole 501. The slide 50 can be set as a PC (thermoplastic material) sheet to provide sliding damping for the push button 20, or can be set as other materials with strong sliding damping, such as silica gel, etc., which are not specifically limited in this application. Therefore, the second housing 102 is provided with a slide 50 located in the accommodating space 103, and the push button 20 can slide on the slide 50. The slide 50 can provide good sliding damping for the push button 20, so that when the push button 20 is pushed to one end or the other end of the first opening 1011, the slide 50 provides sliding damping, which can prevent the push button 20 from automatically rebounding to the initial position after being pushed to one end of the first opening 1011. Furthermore, a through hole 501 corresponding to the push button 20 is opened on the slide 50, and the bottom end of the push button 20 can be attached to the slide 50. A boss is provided at the bottom end of the push button 20, and the boss on the push button 20 can pass through the through hole 501 on the slide 50 to squeeze the elastic contact 401, thereby squeezing the pressure membrane 30, wherein the slide 50 can be adhered to the second shell 102 by bonding, and the slide 50 can also be fixed by other fixing methods, which is not specifically limited in the present application.
[0042] In an optional embodiment, if Figure 1 As shown, a mark 502 is provided on the end surface of the slide 50 close to the first opening 1011, and the push button 20 is at one end or the other end of the first opening 1011 so as to expose the mark 502. Among them, two corresponding different marks 502 can be provided on the end surface of the slide 50, for example, a red mark 502 is provided at one end of the slide 50 to show that the push button 20 is in a working state when squeezing the elastic contact 401, and a black mark 502 is provided at the other end of the slide 50 to show that the push button 20 is in a working state of being separated from the elastic contact 401. The mark 502 can also be provided as a mark 502 of other colors that are easy to identify, or an indicator light of other colors, which is not specifically limited in this application. Therefore, by providing the mark 502 on the end surface of the slide 50 close to the first opening 1011, it is convenient for the user to identify that the push button 20 is in different working states, that is, the on-off state of the line when using it.
[0043] In an optional embodiment, a protrusion 201 is provided on the side of the push button 20 away from the second housing 102, and an anti-slip portion is provided on the protrusion 201 exposed to the first opening 1011. Therefore, by providing the protrusion 201 on the push button 20, it is convenient for the user to push the push button 20 through the protrusion 201, so as to push the push button 20 to one end or the other end of the first opening 1011. In addition, the anti-slip portion is provided on the protrusion 201 exposed to the first opening 1011, which can prevent the user's finger from slipping when pushing the push button 20.
[0044] In a specific embodiment, when the user needs to open an external component, the user can push the protrusion 201 on the push button 20 to make the push button 20 slide in a first direction (not shown) inside the slide groove in a direction perpendicular to the axial direction of the first opening 1011, so that the circuit is at one end of the first opening 1011, and the indicator 502 showing that the push button 20 is open is exposed on the slide 50, indicating that the push button 20 is in an open state. When the push button 20 slides, it can squeeze the elastic contact 401 on the elastic structure 40, so that the elastic contact 401 squeezes the pressure membrane 30. The pressure membrane 30 can accept the pressure brought by the push button 20, so that the impedance of the pressure membrane 30 changes to reach the resistance value of the circuit opening threshold, thereby being able to open the external component. When it is necessary to close the external component, the protrusion 201 on the push button 20 can be pushed to make the push button 20 slide in the direction perpendicular to the axial direction of the first opening 1011 inside the slide groove in the opposite direction to the first direction, so that the push button 20 is at the other end of the first opening 1011, and the indicator 502 of the push button 20 being closed on the slide 50 is exposed, indicating that the circuit is in a closed state, and the push button 20 is disengaged from the elastic contact 401 on the elastic structure 40 when sliding, so that the elastic contact 401 is disengaged from the pressure membrane 30. Since the pressure membrane 30 is not squeezed at this time, the resistance value of the pressure membrane 30 returns to the initial state and reaches the resistance value of the circuit closing threshold, thereby closing the external component.
[0045] In the above manner, the present application can push the push button 20 to move in a direction perpendicular to the axis direction of the first opening 1011 on the housing 10, set an elastic structure 40 in the housing 10, and set a pressure membrane 30 corresponding to the push button 20 on the housing 10, so that the push button 20 can be pushed to move in a direction perpendicular to the axis direction of the first opening 1011 so that the pressure membrane 30 can receive different pressures brought by the elastic structure 40, thereby realizing the dynamic adjustment of the threshold of the line on and off triggered by the push button 20 and adjusting the push button 20 to a specific position to control the on and off of the line. By setting the thickness of the push button 20 and / or the elastic structure 40 in the direction from the push button 20 to the pressure membrane 30 to be variable, the user can make the elastic structure 40 squeeze the pressure membrane 30 when pushing the push button 20, so as to achieve the purpose of opening the external component. By setting the pressure membrane 30 at a certain angle to the moving direction of the push button 20, it is convenient for the push button 20 to drive the elastic structure 40 to squeeze the pressure membrane 30, so that the pressure membrane 30 receives different pressures given by the elastic structure 40. By detachably connecting the first shell 101 and the second shell 102, the push button 20 and the elastic structure 40 can be easily installed. By arranging the elastic structure 40 on the second opening 1021 of the second shell 102, and the elastic structure 40 is located between the push button 20 and the pressure membrane 30, the push button 20 can squeeze the pressure membrane 30 through the elastic structure 40. By arranging the elastic contact 401 on the elastic structure 40, and the thickness of the elastic contact 401 is gradually thickened or thinned, the elastic contact 401 can move up and down, and the elastic contact 401 can squeeze or separate from the pressure membrane 30. By opening the third opening 4011 on the elastic structure 40, and connecting the elastic contact 401 in the third opening 4011, the elastic contact 401 squeezes or separates from the pressure membrane 30, and the circuit on-off threshold can be reached to open or close the external component. By providing a sliding groove at the opening of the first opening 1011, the push button 20 slides inside the sliding groove, which can prevent the push button 20 from popping out of the first housing 101 when sliding in the first opening 1011. By providing a sliding sheet 50 adapted to the edge of the accommodating space 103 on the second housing 102, and providing a through hole 501 in the sliding sheet 50, the sliding sheet 50 can provide good sliding damping for the push button 20, which can prevent the push button 20 from automatically rebounding to the initial position after being pushed to the end of the first opening 1011. By providing a mark 502 on the end surface of the sliding sheet 50 close to the first opening 1011, it can be displayed whether the push button 20 is in the state of squeezing or disengaging the elastic contact 401 and the on-off state of the circuit. By providing a protrusion 201 and an anti-slip portion on the push button 20, it is convenient for the user to move the push button 20 through the protrusion 201, which can prevent the finger from sliding when moving the push button 20.
[0046] The present application also provides a communication device, which includes: a push button assembly, which is arranged in the communication device, and the push button assembly is the push button assembly of any of the above-mentioned embodiments.
[0047] In an optional embodiment, the communication device further includes an electronic component (not shown), which is disposed in the housing 10, and the pressure membrane 30 is disposed on the electronic component. Therefore, when the pressure membrane 30 receives different pressures, the resistance value of the pressure membrane 30 itself changes, thereby controlling the external components according to the electronic component to realize different terminal functions.
