[0045] In the embodiment of the utility model, the button 500 assembly includes:
[0046] The housing 100 is provided with an assembly hole 110;
[0047] A first bracket 200 is rotatably connected to the inner wall of the assembly hole 110;
[0048] The second bracket 300 is slidably disposed on the first bracket 200;
[0049] The circuit board 400 has a first contact 410 and a second contact 420, wherein the first contact 410 is disposed opposite to the first bracket 200, and the second contact 420 is disposed opposite to the second bracket 300; and
[0050] The button 500 drives the first bracket 200 and the second bracket 300 to be connected. The button 500 drives the first bracket 200 to rotate by its own tilting so that the first bracket 200 triggers the first contact 410, or the button 500 drives the second bracket 300 to slide by its own linear motion so that the second bracket 300 triggers the second contact 420.
[0051] The key 500 assembly in a technical solution of an embodiment of the utility model comprises a housing 100, a first bracket 200, a second bracket 300, a circuit board 400 and a key 500. The housing 100 is provided with an assembly hole 110. The first bracket 200 can rotate along the inner wall of the assembly hole 110. The second bracket 300 is inserted through the first bracket 200 and can slide up and down relative to the first bracket 200. The circuit board 400 is provided with a first contact 410 and a second contact 420. The first contact 410 is opposite to the first bracket 200 and can be triggered by rotating the first bracket 200. The second contact 420 is opposite to the second bracket 300 and can be triggered by sliding the first bracket 200. The button 500 is driven to connect to the first bracket 200. When the user operates the button 500 to tilt, the button 500 drives the first bracket 200 to rotate, thereby triggering the first contact 410. The button 500 is also driven to connect to the second bracket 300. When the user presses the button 500, the button 500 moves linearly, thereby driving the second bracket 300 to slide, thereby triggering the second contact 420. The first contact 410 and the second contact 420 are triggered respectively by different movement forms of a button 500, thereby reducing the number of buttons 500, and thus reducing the gaps between buttons 500 and buttons 500, thereby reducing the possibility of foreign objects being stuck in the button 500.
[0052] Specifically in this embodiment, the button 500 component is applied to a remote controller, the button 500 triggers the first contact 410 to form a direction key of the remote controller, and the button 500 triggers the second contact 420 to form a confirmation key of the remote controller.
[0053] Optionally, the circuit board 400 has a plurality of first contacts 410 , and the plurality of first contacts 410 are arranged around the second contacts 420 . The button 500 tilts in different directions to drive the first bracket 200 to rotate in different directions to trigger different first contacts 410 .
[0054] In this embodiment, there are multiple first contacts 410 on the circuit board 400, and the multiple first contacts 410 are distributed on a virtual circle. The second contact 420 is located at the center of the virtual circle. The button 500 tilts in different directions to make the first bracket 200 rotate in different directions, thereby triggering different first contacts 410, realizing the direction keys of different directions on the remote control, with a simple structure and easy operation. Specifically in this embodiment, four first contacts 410 are provided on the circuit board 400, corresponding to the "up, down, left, right" direction control functions of the remote control, respectively. The four first contacts 410 are evenly spaced outside the second contacts 420 to ensure the accuracy of control in each direction. Pressing the middle part of the button 500 makes the second bracket 300 press down to trigger the second contact 420, and pressing the edge part of the button 500 corresponding to the first contact 410 makes the first bracket 200 rotate to trigger the first contact 410. The four direction keys and one confirmation key are operated by one button 500, which further reduces the gap between the buttons 500, thereby reducing the possibility of foreign objects being stuck.
[0055] Optionally, the button 500 has a natural state, a pressed state and a tilted state. In the natural state, there is a gap between the button 500 and the first bracket 200, and the gap is greater than the stroke of the linear motion of the button 500; in the pressed state, the button 500 abuts against the second bracket 300 to drive the second bracket 300 to slide; in the tilted state, the button 500 abuts against the first bracket 200 to drive the first bracket 200 to rotate.
[0056] Reference Figure 1 In this embodiment, the button 500 has a natural state, a pressed state and a tilted state. In the natural state of the button 500, the button 500 is spaced apart from the first bracket 200, and the space between the button 500 and the first bracket 200 is greater than the stroke of the button 500 driving the second bracket 300 downward, thereby avoiding the problem of driving the first bracket 200 to move when the button 500 vertically presses the second bracket 300, and ensuring the accuracy of the trigger contact. Specifically, in this embodiment, the space between the button 500 and the first bracket 200 is 3mm, and the vertical pressing stroke of the button 500 is 2mm. In the pressed state of the button 500, the user presses the middle part of the button 500 to make the button 500 vertically downward, and the button 500 abuts against the second bracket 300 so that the button 500 drives the second bracket 300 to slide downward, thereby triggering the second contact 420, which is easy to operate. The user presses the edge of the button 500 to put the button 500 in a tilted state. The tilted button 500 approaches the first bracket 200 and then drives the first bracket 200 to rotate downward, so that the first bracket 200 triggers the first contact 410, which is easy to operate.
[0057] Optionally, the button 500 assembly further includes a buffer member 600 , which is disposed between the button 500 and the first bracket 200 and connects the button 500 and the first bracket 200 .
[0058] Reference Figure 1 and Figure 4 In this embodiment, the button 500 assembly further includes a buffer 600, which can be connected to the button 500 and the first bracket 200 by bonding or hot melting, so that the button 500 is connected to the first bracket 200, reducing the possibility of the button 500 falling off. The buffer 600 has good deformation performance and can be made of foam or other materials. When the middle part of the button 500 is pressed down to drive the second bracket 300, the buffer 600 deforms to absorb the energy transmitted by the button 500, and will not be transmitted to the first bracket 200 below, further avoiding the button 500 vertically pressing down the second bracket 300 and driving the first bracket 200, ensuring the accuracy of the trigger contact; on the other hand, the buffer 600 makes the button 500 press smoothly, enhances the feedback of the button 500 assembly to the user's hand, and enables the user to obtain a better use experience. Specifically in this embodiment, the buffer 600 is annular and is sleeved on the outside of the second bracket 300. The annular buffer 600 has a larger connection area with the button 500 and the first bracket 200, and a higher connection strength, which further reduces the possibility of the button 500 falling off. When the middle part of the button 500 is pressed down, the annular buffer 600 is subjected to more uniform force and deforms more uniformly, thereby absorbing more energy to prevent the button 500 from driving the first bracket 200, and extending the service life of the buffer 600.
[0059] Optionally, the button 500 is provided with a groove 510 , which is provided on a side of the button 500 away from the first bracket 200 and is recessed toward a direction close to the first bracket 200 .
[0060] Reference Figure 6 In this embodiment, a groove 510 is provided on the side of the button 500 away from the first bracket 200, and the groove 510 is recessed in the direction close to the first bracket 200. Specifically in this embodiment, the center of the groove 510 is located at the center of the button 500, and the edge of the groove 510 extends to the periphery of the button 500. The user presses the bottom of the groove 510 to trigger the second contact 420, and the user presses the edge of the groove 510 to trigger the first contact 410, so that the button 500 areas corresponding to the first contact 410 and the second contact 420 have a large shape difference, which reduces the possibility of the user pressing the wrong position and improves the convenience of use of the button 500 component.
[0061] Optionally, the first bracket 200 includes:
[0062] The support portion 210 is disposed opposite to the first contact point 410; and
[0063] The rotating portion 220 is protruded from the supporting portion 210 and is provided with an outer spherical surface 221 . The inner wall of the assembly hole 110 is provided with an inner spherical surface 111 corresponding to the outer spherical surface 221 . The inner spherical surface 111 cooperates with the outer spherical surface 221 to enable the first bracket 200 to rotate along the inner wall of the assembly hole 110 .
[0064] Reference Figure 1 and Figure 5 In this embodiment, the first bracket 200 includes a support portion 210 and a rotating portion 220. The rotating portion 220 is rotatably connected to the inner wall of the assembly hole 110, so that the support portion 210 touches the first contact 410. The rotating portion 220 is provided with an outer spherical surface 221, and the inner wall of the assembly hole 110 is provided with an inner spherical surface 111. The first bracket 200 and the housing 100 are connected by a ball pair through the cooperation of the inner spherical surface 111 and the outer spherical surface 221. The first bracket 200 has a higher degree of freedom to rotate relative to the housing 100, and the first bracket 200 can rotate at a wider angle, thereby ensuring that the first bracket 200 can trigger the first contact 410, reducing the possibility of the first bracket 200 being stuck. Specifically in this embodiment, a convex rib 222 is provided on the outer spherical surface 221, and each first contact 410 is correspondingly provided with a convex rib 222. The convex rib 222 can play a certain guiding role, so that the first bracket 200 rotates as much as possible in the direction of triggering the first contact 410, thereby improving the accuracy of the button 500 triggering the contact.
[0065] Optionally, the first bracket 200 further includes a protrusion 230, one end of the protrusion 230 is fixed to the support portion 210, and the other end of the protrusion 230 extends toward a direction close to the first contact point 410; and / or,
[0066] The first bracket 200 further includes a hook 240 . The hook 240 is disposed on the periphery of the support portion 210 . The first bracket 200 is connected to the housing 100 via the hook 240 .
[0067] Reference Figure 5 In this embodiment, a protrusion 230 is provided on the support portion 210 in the direction toward the first contact 410, and four protrusions 230 are provided corresponding to the four first contacts 410. The protrusions 230 and the first contacts 410 correspond one to one. The first contacts 410 are triggered by the protrusions 230, which can ensure that the first contacts 410 are triggered after the first bracket 200 rotates, thereby reducing the problem of pressing the button 500 to drive the first bracket 200 to rotate but not triggering the first contacts 410.
[0068] Reference Figure 5In this embodiment, the first bracket 200 further includes a hook 240, and the first bracket 200 is connected to the housing 100 through the hook 240, so that the first bracket 200 is easy to disassemble, and the convenience of key 500 assembly maintenance is improved. The hook 240 is arranged on the periphery of the support portion 210. Specifically in this embodiment, four hooks 240 are arranged on the periphery of the support portion 210, and the four hooks 240 are evenly spaced to improve the strength and stability of the connection between the first bracket 200 and the housing 100; the four hooks 240 are staggered with the four protrusions 230 to avoid the problem that the hook 240 blocks the rotation of the first bracket 200.
[0069] Optionally, the second bracket 300 includes:
[0070] The bracket body 310 is disposed through the first bracket 200; and
[0071] The universal head 320 has a first end and a second end. The first end is hemispherical and abuts against the second contact 420 , and the second end is connected to the bracket body 310 . The second bracket 300 triggers the second contact 420 through the first end.
[0072] Reference Figure 7 In this embodiment, the second bracket 300 includes a bracket body 310 and a universal head 320. The button 500 pushes the bracket body 310 vertically downward, and the bracket body 310 pushes the universal head 320 to trigger the second contact 420. The first end of the universal head 320 is hemispherical, and the second end of the universal head 320 is connected to the bracket body 310. When the button 500 tilts to drive the first bracket 200 to rotate, the button 500 or the first bracket 200 may have a part of the force transmitted to the second bracket 300, but because the second bracket 300 is located in the center and the first end of the universal head 320 is hemispherical, the second bracket 300 will only rotate slightly around the first end of the universal head 320, and will not press down the second contact 420, thereby avoiding triggering the second contact 420 when the button 500 triggers the first contact 410, further improving the accuracy of the triggering contact. Specifically in this embodiment, a receiving groove is provided at one end of the bracket body 310 facing the universal head 320, and the second end of the universal head 320 is inserted into the receiving groove, which has a simple structure and is easy to assemble.
[0073] Optionally, the button 500 assembly further includes an elastic member 700 , which is disposed between the first bracket 200 and the first contact 410 . The first bracket 200 drives the elastic member 700 to deform toward the direction approaching the first contact 410 to trigger the first contact 410 .
[0074] Reference Figure 1In this embodiment, the button 500 assembly also includes an elastic member 700, which is disposed between the first bracket 200 and the first contact 410. When a user presses the edge of the button 500 to rotate the first bracket 200, the first bracket 200 presses the elastic member 700 to deform, thereby causing the elastic member 700 to trigger the first contact 410, thereby improving the user experience when pressing the button 500. The elastic member 700 may be a spring and may be made of materials such as rubber or silicone. Specifically in this embodiment, the elastic member 700 is a silicone pad, which is arranged between the shell 100 and the circuit board 400. The shell 100 is provided with an avoidance hole 120 corresponding to the position of the first contact 410. When the first bracket 200 rotates, the protrusion 230 passes through the avoidance hole 120 to press the silicone pad, so that the silicone pad triggers the first contact 410. The structure is simple and easy to assemble. The silicone pad can also play a barrier role, reducing the possibility of dust, water, etc. in the external environment entering the shell 100 from around the button 500 and damaging the circuit board 400, thereby extending the service life of the button 500 component.
[0075] The utility model also proposes a remote control, which includes the above-mentioned button 500 component. The specific structure of the button 500 component refers to the above-mentioned embodiment. Since the remote control adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, by adopting the above-mentioned button 500 component, the number of buttons 500 on the remote control is reduced, thereby reducing the gap between buttons 500 and buttons 500 and the gap between buttons 500 and housing 100, thereby reducing the possibility of foreign objects being stuck in the remote control and extending the service life of the remote control.
[0076] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
