Description

Technical Field

[0001] The utility model relates to the technical field of control switches, in particular to a rotary button. Background Art

[0002] Rotary buttons are a common user input interface element found in various electronic devices and control panels. Traditional rotary buttons typically consist of a rotatable knob and an encoder, allowing users to adjust or select parameters by rotating the knob. However, this simple rotary function often fails to meet the multifunctionality requirements of modern devices.

[0003] As electronic products become increasingly complex, user interface design needs to be more flexible and diverse. A single rotation function can no longer meet users' demands for fast, precise, and diverse control. For example, in audio equipment, users may need to adjust the volume by rotating the knob while also wanting to switch between different sound modes by pressing the knob. Furthermore, the structural design of traditional rotary buttons is often relatively simple, and their press-to-rebound function relies on springs or the button's own rebound to achieve reset. The former increases component parts, thereby increasing material costs, and rotary buttons are prone to loosening or wear between structural components after long-term use, affecting their service life and reliability. The latter, with only the button's own rebound, lacks good tactile feedback, which can cause user discomfort or inaccurate operation during use. Utility Model Content

Thus, a feature identified as "first," "second," and "third" may explicitly or implicitly include one or more of the features.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0048] The following is combined with Figures 1 to 4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0049] A rotary button, comprising an encoder 1, a rotary base 2, a pressing member 3, a knob cover 4 and a PCB board 5;

[0050] The encoder 1 is arranged on the top surface of the PCB board 5. A hollow rotating cylinder 11 is provided on the top of the encoder 1. The rotating seat 2 is a hollow cylindrical shape and is sleeved on the outside of the rotating cylinder 11.

[0051] The PCB board 5 is provided with a tact switch 51. The pressing member 3 is provided in the hollow space between the rotating base 2 and the rotating cylinder 11. The top of the pressing member 3 is connected to the knob cover 4, and the bottom of the pressing member 3 faces the tact switch 51.

[0052] An elastic structure 6 is provided at the bottom of the pressing member 3, and the elastic structure 6 is integrally formed with the pressing member 3. When a downward force is applied to the pressing member 3, the elastic structure 6 undergoes elastic deformation and the bottom of the pressing member 3 moves downward to touch the tact switch 51. When the force applied to the pressing member 3 is removed, the elastic structure 6 elastically recovers and the bottom of the pressing member 3 moves upward to leave the tact switch 51.

[0053] The rotary button of this utility model achieves both rotation and pressing operations through the coordinated operation of multiple components. The encoder 1 is mounted on the top surface of the PCB board 5, and the rotation operation is achieved through the cooperation of the rotating cylinder 11 and the rotating base 2. The pressing member 3 is located in the hollow space between the rotating base 2 and the rotating cylinder 11. Its top is connected to the knob cover 4, and its bottom faces the tactile switch 51. An elastic structure 6 is provided at the bottom of the pressing member 3. When the pressing member 3 applies a downward force, the elastic structure 6 elastically deforms, causing the bottom of the pressing member 3 to move downward and contact the tactile switch 51, thereby achieving the pressing operation. When the force is removed, the elastic structure 6 returns to its original state, causing the bottom of the pressing member 3 to move upward and disengage the tactile switch 51, ensuring the sensitivity and reliability of the pressing operation. The elastic structure 6 provides the rotary button with enhanced tactile feedback when pressing the button. When the user presses the button, they can feel a noticeable pressure and a rebound effect, thereby improving the accuracy and comfort of the operation. This excellent tactile feedback helps users control the device more accurately and reduces the possibility of misoperation.

[0054] To further illustrate, compared with the traditional rotary button that relies on a spring to achieve pressing and rebounding, the rotary button of the present invention realizes the pressing and rebounding functions through the elastic structure 6 integrated at the bottom of the pressing member 3. Preferably, the elastic structure 6 is made of a material such as thermoplastic elastomer (TPE), silicone or rubber to ensure the elastic deformation of the elastic structure 6. The integrated structure of the pressing member 3 and the elastic structure 6 reduces the need for additional components (such as springs), thereby simplifying the product structure, reducing material costs, and reducing the risk of failure due to loose or wear of components. Since the elastic structure 6 and the pressing member 3 are integrally formed, the assembly gap and friction points between the components are reduced, so during long-term use, the looseness and wear problems between the structural components are significantly improved. This not only extends the service life of the product, but also improves the stability and reliability of its operation.

[0055] Furthermore, the elastic structure 6 includes a vertical connecting portion 61, a horizontal extending portion 62 and a vertical supporting portion 63;

[0056] The bottom of the vertical connection portion 61 is connected to the top surface of the horizontal extension portion 62 , and the top of the vertical connection portion 61 is connected to the bottom of the pressing member 3 ;

[0057] The top of the vertical support portion 63 is connected to the bottom surface of the horizontal extension portion 62 , and the bottom of the vertical support portion 63 abuts against the PCB board 5 .

[0058] The vertical connection portion 61, horizontal extension portion 62, and vertical support portion 63 of the elastic structure 6 cooperate with each other. When the pressing member 3 is subjected to a downward force, the vertical connection portion 61 and horizontal extension portion 62 effectively transmit the force, causing the vertical support portion 63 to deform, thereby moving the bottom of the pressing member 3 downward toward the PCB and triggering the touch switch 51. When the force is removed, the vertical support portion 63 returns to its original state, driving the pressing member 3 back to its initial position, ensuring that the touch switch 51 is no longer triggered. This design not only ensures the stability and reliability of the pressing member, but also improves the durability and service life of the rotary button.

[0059] To further illustrate, the design of the vertical connection portion 61, the horizontal extension portion 62 and the vertical support portion 63 enables the elastic structure 6 to undergo more uniform and controllable elastic deformation when subjected to pressure. The horizontal extension portion 62 serves as a transition portion, which helps to disperse and transfer the force from the vertical connection portion 61 to the vertical support portion 63, and the elastic structure 6 is compressed or bent by the force deformation, so that the bottom of the pressing member 3 can contact and trigger the touch switch 51 more smoothly. At the same time, this design also helps the elastic structure 6 to return to its original state more quickly after the external force is removed, thereby improving the response speed and accuracy of the operation. Although the structure of the elastic structure 6 seems complicated, in fact, this design makes the manufacturing process of the elastic structure 6 more standardized and modular. The various components can be formed in one go through processes such as injection molding or molding, reducing the difficulty and cost of manufacturing. At the same time, due to the compact structure and easy disassembly, subsequent maintenance and replacement work are also made simpler.

[0060] Due to the optimized design of the elastic structure 6, the user will feel a smoother and more stable pressing experience when operating the rotary button, especially through the elastic deformation of the elastic structure 6 as feedback of the pressing, which makes the timing more accurate and improves the overall user experience.

[0061] Furthermore, the number of the elastic structures 6 is no less than two;

[0062] The vertical connection portion 61 and the vertical support portion 63 are respectively provided on opposite sides of the horizontal extension portion 62. The vertical connection portion 61 is located on the outer side of the bottom of the pressing member 3 away from the center, and the vertical support portion 63 is located on the inner side of the bottom of the pressing member 3 close to the center.

[0063] Several elastic structures 6 are evenly arranged along the bottom of the pressing member 3 .

[0064] The number of elastic structures 6, no less than two, ensures the stability of the pressing member 3 during pressing and releasing. The vertical connecting portion 61 and the vertical supporting portion 63 are located on opposite sides of the horizontal extension 62. The vertical connecting portion 61 is located on the outside of the bottom of the pressing member 3, away from the center, while the vertical supporting portion 63 is located on the inside of the bottom of the pressing member 3, closer to the center. This design ensures that the pressing member 3 is evenly stressed during pressing, preventing tilting. The uniform arrangement of multiple elastic structures 6 along the bottom of the pressing member further enhances the stability and reset effect of the pressing member 3.

[0065] Furthermore, the horizontal extension portion 62 is in a flat plate shape, and the horizontal extension portion 62 is bent and deformed;

[0066] The vertical support portion 63 is a cylindrical or tubular structure, and the vertical support portion 63 undergoes compression deformation.

[0067] The horizontal extension 62 is designed as a flat plate that allows for bending, allowing the user to trigger the deformation with a gentle rotation of the button, thereby enhancing the button's sensitivity. This design makes the rotation operation more delicate and improves the user experience. The vertical support portion 63 adopts a cylindrical or tubular structure, which can undergo compression deformation when subjected to pressure while maintaining good stability and support. This not only ensures the stability of the rotary button during long-term use, but also reduces the risk of failure due to structural loosening or deformation.

[0068] The design of the horizontal extension 62 and vertical support 63 allows the pressing member 3 to achieve overall elastic deformation when subjected to pressing force through bending of the horizontal extension 62 and compression of the vertical support 63. This design ensures that the pressing member 3 can effectively move downward and trigger the touch switch 51 during the pressing process. Furthermore, after the pressing force is released, the elastic structure 6 can quickly return to its original shape, returning the pressing member 3 to its original position. This structural design not only improves the reliability and service life of the rotary button, but also ensures accurate and tactile operation.

[0069] Furthermore, the pressing member 3 is in the shape of a long cylinder, and a first position limiting guide portion 31 is provided on two opposite front and rear sides of the outer wall of the pressing member 3;

[0070] The rotating cylinder 11 includes an inner cylinder 111 and an outer cylinder 112. The inner cylinder 111 is fixed relative to the PCB board 5. The outer cylinder 112 is rotatably mounted on the outer side of the inner cylinder 111. Second limiting guide portions 1111 are provided on two opposite front and rear sides of the inner wall of the inner cylinder 111.

[0071] The first position limiting guide portion 31 and the second position limiting guide portion 1111 on the same side are cooperatively connected.

[0072] The design of the first limiting guide portion 31 and the second limiting guide portion 1111 ensures that the pressing member 3 can be stably disposed within the hollow space between the rotating base 2 and the encoder 1 during the rotation of the outer cylinder 112 of the rotating cylinder driven by the rotating base 2, so that the pressing member 3 is not affected by the rotation function, thereby preventing the pressing member from deflecting or shaking during the rotation process. The mating connection between the first limiting guide portion 31 and the second limiting guide portion 1111 provides a precise guiding function during the assembly of the pressing member 3 and the encoder 1, and after the two components are installed, the two structures have the limiting and locking functions during the use of the rotary button, thereby improving the operational stability and service life of the rotary button.

[0073] Furthermore, the first limiting guide portion 31 is composed of a plurality of first ribs 311 and first grooves 312 that are alternately distributed in sequence;

[0074] The second limiting guide portion 1111 is composed of a plurality of second grooves 11111 and second ribs 11112 that are alternately distributed in sequence;

[0075] The first rib 311 corresponds to the second groove 11111 , and the first groove 312 corresponds to the second rib 11112 .

[0076] The staggered arrangement of ribs and grooves in the first and second limiting guides 31 and 1111 creates a stable guiding and limiting structure between the push button 3 and the encoder (inner cylinder 111). The guiding function ensures that the push button 3 moves along a predetermined trajectory during downward pressure, preventing it from shifting or getting stuck. The limiting function ensures that the rotating base 2, when rotating the rotating cylinder 11, does not affect the push button 3. This design not only improves the operating accuracy of the rotary button but also extends its service life.

[0077] Furthermore, the staggered arrangement of ribs and grooves not only provides guidance but also enhances the structural strength of the pressing element and rotating cylinder. This design allows the components to better disperse stress when subjected to rotational or pressing forces, preventing damage caused by localized stress concentration, thereby extending the product's service life.

[0078] Furthermore, the outer side wall of the pressing member 3 is provided with limiting ribs 32 on the left and right opposite sides;

[0079] The inner side wall of the inner cylinder 111 is provided with second limiting grooves 1112 on two opposite sides.

[0080] The limiting rib 32 on the same side is connected in cooperation with the second limiting groove 1112 .

[0081] The design of the retaining rib 32 and the second retaining groove 1112 ensures that the pressing member 3 can be stably retained and guided during rotation. The mating connection between the retaining rib and the second retaining groove prevents the pressing member from shifting or shaking during rotation, thereby improving the operational stability and service life of the rotary button.

[0082] Furthermore, the outer wall of the outer cylinder 112 is provided with a plurality of clamping grooves 1121, and the clamping grooves 1121 are recessed inward from the outer wall of the outer cylinder 112;

[0083] The rotating seat 2 includes an outer ring 21 and an inner ring 22. The inner ring 22 is arranged inside the outer ring 21. The outer wall of the top of the inner ring 22 is connected to the inner wall of the outer ring 21. The inner ring 22 is provided with a plurality of elastic blocks 221.

[0084] The inner ring 22 is sleeved on the outside of the outer cylinder 112 , and the plurality of elastic blocks 221 are matched and connected with the plurality of clamping grooves 1121 in a one-to-one correspondence.

[0085] The outer wall of the outer cylinder 112 is provided with a number of snap-in grooves 1121, which provide a structure for mating with the elastic snap-in blocks 221 on the inner ring of the rotating base. The inner ring of the rotating base is connected to the snap-in grooves 1121 of the outer cylinder via the elastic snap-in blocks 221 in a one-to-one correspondence. This design ensures a stable connection between the rotating base 2 and the outer cylinder 112. The design of the elastic snap-in blocks 221 allows for a certain degree of elastic deformation during installation and removal, thereby ensuring the reliability of the connection and the convenience of operation. Through this structural design, the rotary button can maintain a good operating feel during use while also having reliable mechanical performance.

[0086] Furthermore, the outer wall of the outer cylinder 112 is further provided with an installation positioning groove 1122, which is recessed inward from the outer wall of the outer cylinder 112. The installation positioning groove 1122 extends in the vertical direction, and the top of the installation positioning groove 1122 passes through the top of the outer cylinder 112.

[0087] The inner side wall of the inner ring 22 is provided with an installation positioning block, and the installation positioning block is extended in the vertical direction;

[0088] The installation positioning block is cooperatively connected with the installation positioning groove 1122 .

[0089] The design of the mounting positioning groove 1122 and the mounting block ensures precise positioning and a stable connection between the rotating base 2 and the outer cylinder 112. The mounting positioning groove 1122 extends vertically through the top of the outer cylinder 112, allowing the mounting block to be accurately inserted and secured vertically. This design not only improves the operational stability of the rotary button but also reduces potential wobble and deviation during rotation, thereby increasing the reliability and service life of the rotary button.

[0090] Furthermore, the upper portion of the pressing member 3 is provided with a clamping block 33 on both sides thereof, and the top surface of the pressing member 3 is provided with a positioning mounting hole 34;

[0091] The bottom of the knob cover 4 is provided with a clamping ring 41 on two opposite sides of the front and rear, and the bottom surface of the knob cover 4 is provided with a positioning mounting column 42;

[0092] On the same side, the clamping block 33 is connected to the clamping ring 41 by means of a snap fit, and the positioning mounting column 42 is connected to the positioning mounting hole 34 by means of a snap fit.

[0093] The upper portion of the pressing member 3 is provided with snap-fit ​​blocks 33 on opposite front and rear sides, and a positioning hole 34 is provided on its top surface. The bottom portion of the knob cover 4 is provided with snap-fit ​​rings 41 on opposite front and rear sides, and a positioning post 42 is provided on its bottom surface.
