Description

Technical Field

[0001] This utility model relates to the field of button technology, and in particular to a rotary button with damped tactile feedback. Background Technology

[0002] A button is a physical or virtual interactive device that uses a finger to press and trigger commands. Broadly speaking, it encompasses physical buttons such as keyboards and remote controls, as well as virtual buttons on a screen. Buttons can be categorized into three types: mechanical buttons, electronic touch buttons, and software-simulated buttons. In industrial design, button formats have expanded to include knobs, touchscreens, and other types, taking into account both visual aesthetics and interactive feedback.

[0003] With the development of technology, various remote buttons have appeared on the market. These buttons control devices using methods such as Bluetooth. However, whether they are ordinary buttons or remote buttons, their functions are relatively simple, only providing button functionality, thus failing to meet the needs of consumers. Therefore, there is a need to design a DIY remote rotary button. Utility Model Content

[0004] The purpose of this invention is to provide a rotary button with a damped feel that is multifunctional, structurally stable, and improves the user experience.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions: A rotary button with damped tactile feedback includes a base, a fixed bracket, a PCB, an electronic button, and a button cover. The bottom of the fixed bracket is connected to the base, the PCB is located inside the fixed bracket, and the electronic button is connected to the PCB. The top of the fixed bracket is provided with a pressing spring arm, and the outer side is provided with a rotating spring arm. The button cover is connected to the fixed bracket and can be pressed and rotated relative to the fixed bracket. After the button cover is closed with the fixed bracket, the pressing spring arm and the rotating spring arm will produce a damping effect on the button cover.

[0006] In one embodiment, a spring-loaded movable position is formed between the bottom of the pressing spring arm and the fixed bracket, and an upwardly extending spring-loaded column is provided at the top.

[0007] In one embodiment, the rotating spring arm has an arched structure, and a damping protrusion is provided on the outer wall of the arched portion in the middle of the rotating spring arm.

[0008] In one embodiment, the inner wall of the button cover is provided with a serrated texture.

[0009] In one embodiment, the outer wall of the fixed bracket is provided with a bead unit, which includes a fixed cylinder, an elastic element and a bead. A limiting hole is opened at one end of the fixed cylinder. The elastic element and the bead are respectively installed in the fixed cylinder, and one end of the elastic element abuts against the bead so that the bead protrudes out of the limiting hole and cooperates with the serrated pattern.

[0010] In one embodiment, the diameter of the limiting hole is smaller than the diameter of the bead.

[0011] In one embodiment, a limit buckle is provided on the inner side of the fixed bracket, and a limit platform corresponding to the limit buckle is provided inside the button cover.

When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1 to 3A rotary button with damped tactile feedback includes a base 100, a fixed bracket 200, a PCB 300, an electronic button 400, and a button cover 500. The bottom of the fixed bracket 200 is connected to the base 100, the PCB 300 is located inside the fixed bracket 200, and the electronic button 400 is connected to the PCB 300. The top of the fixed bracket 200 is provided with a pressing spring arm 210, and the outer side is provided with a rotating spring arm 220. The button cover 500 is closed and connected to the fixed bracket 200 and can be pressed and rotated relative to the fixed bracket 200. After the button cover 500 is closed and connected to the fixed bracket 200, the pressing spring arm 210 and the rotating spring arm 220 will produce a damping effect on the button cover 500.

[0022] Specifically, in this embodiment, the electronic button 400 is soldered to the PCB 300 using a surface mount method. The PCB 300 is then installed inside the fixed bracket 200, and the fixed bracket 200 is connected to the base 100 using screws 700. During connection, the screws 700 penetrate the PCB 300, thereby achieving the connection between the base 100, the PCB 300, and the fixed bracket 200, and making the PCB 300 more stable after assembly. Finally, the button cover 500 is closed and connected to the fixed bracket 200, thus completing the assembly of the button. After the button cover 500 is connected to the fixed bracket 200, the button cover 500 can be pressed and rotated relative to the fixed bracket 200. Pressing the button cover 500 realizes the pressing function of the electronic button, and rotating the button cover 500 realizes the rotation function, thus giving the button a multi-functionality of pressing and rotating.

[0023] Since a pressing spring arm 210 and a rotating spring arm 220 are respectively provided on the top and outer wall of the fixed bracket 200, when the button cover 500 is closed and connected to the fixed bracket 200, the pressing spring arm 210 and the rotating spring arm 220 can generate a reverse spring force, which can make the button cover 500 and the fixed bracket 200 more stable after connection. At the same time, it can also produce a damping effect on the button cover 500, so that the button cover 500 can obtain a stable rotation force and pressing force during rotation and pressing, thereby improving the feel of the knob button and enhancing the user experience.

[0024] Of course, in order to ensure that the button cover 500 can act on the electronic button 400 when pressed, a pressing groove 530 is provided on the inner top surface of the button cover 500. The pressing groove 530 corresponds to and cooperates with the button of the electronic button 400. When the button cover 500 is pressed down, the pressing groove 530 can drive the button of the electronic button 400 to press down, thereby realizing the button function.

[0025] Furthermore, the electronic button 400 is a button in the existing technology, and will not be described in detail here.

[0026] Furthermore, since the button cover 500 needs to be pressed and rotated relative to the fixed bracket 200 after the button cover 500 and the fixed bracket 200 are connected, in this embodiment, a limit buckle 230 is provided on the inner side of the fixed bracket 200, and a limit platform 520 corresponding to the limit buckle 230 is provided inside the button cover 500, and the limit platform 520 has a ring structure. When the button cover 500 and the fixed bracket 200 are connected, the limit buckle 230 and the limit platform 520 are fastened together, so that the button cover 500 and the fixed bracket 200 can be limited and connected. And through the limit platform 520 with a ring structure, the limit platform 520 can always be fastened to the limit buckle 230 when the button cover 500 is rotated, thereby preventing the button cover 500 and the fixed bracket 200 from separating from each other.

[0027] Please see Figure 2 In order to ensure that the button cover 500 can produce a damping effect, a spring-loaded movable position 211 is formed between the bottom of the pressing spring arm 210 and the fixed bracket 200 in this embodiment, and a spring-loaded column 212 extending upward is provided at the top. The rotating spring arm 220 has an arched structure, and a damping protrusion 221 is provided on the outer wall of the arched part in the middle of the rotating spring arm 220. The spring-loaded movable position 211 allows the pressing spring arm 210 to generate a certain elastic force, while the arched rotating spring arm 220 also generates a certain elastic force. When the button cover 500 is closed with the fixed bracket 200, the spring-loaded column 212 extending from the top of the pressing spring arm 210 abuts against the inner top of the button cover 500, and the damping protrusion 221 of the rotating spring arm 220 abuts against the inner sidewall of the button cover 500. Thus, the spring-loaded column 212 and the damping protrusion 221 generate a damping effect on the button cover 500, so that the button cover 500 obtains a stable rotational force and pressing force during rotation and pressing. At the same time, the opposing forces of the pressing spring arm 210 and the rotating spring arm 220 make the connection between the button cover 500 and the fixed bracket 200 more stable.

[0028] Finally, please see Figure 3 and Figure 4 To improve the tactile feel of the buttons, in this embodiment, a serrated texture 510 is provided on the inner wall of the button cover 500. At the same time, a ball bearing unit 600 is provided on the outer wall of the fixed bracket 200. The ball bearing unit 600 includes a fixed cylinder 610, an elastic element 620, and a ball bearing 630. A limiting hole 611 is provided at one end of the fixed cylinder 610. The elastic element 620 and the ball bearing 630 are respectively installed in the fixed cylinder 610, and one end of the elastic element 620 abuts against the ball bearing 630 so that part of the ball bearing 630 protrudes out of the limiting hole 611 and cooperates with the serrated texture 510.

[0029] A hole is made on the outer wall of the fixed bracket 200, and the fixed cylinder 610 of the ball bearing unit 600 is interference-fitted into the hole. At the same time, the elastic element 620 and the ball bearing 630 are respectively installed in the fixed cylinder 610. The elastic element 620 is a spring. The elastic force of the elastic element 620 drives the ball bearing 630 to protrude from the limiting hole 611 of the fixed cylinder 610. When the button cover 500 is closed and connected to the fixed bracket 200, the serrated pattern 510 on the inner wall of the button cover 500 will cooperate with the protruding part of the ball bearing 630. When the button cover 500 is rotated, the cooperation between the serrated pattern 510 and the ball bearing 530 can produce a clicking sound, thus making the button cover 500 make a sound when rotating, thereby improving the user experience.

[0030] In addition, to prevent the elastic element 620 from pushing the ball 630 out completely into the fixed cylinder 610, the diameter of the limiting hole 611 is smaller than the diameter of the ball 630 in this embodiment. Therefore, the elastic element 620 can only push out part of the ball 630 so that it can cooperate with the serrated pattern 510 to produce a sound, thereby giving the button a good feedback experience to the user in terms of both hearing and touch.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
