Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0037] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0038] A knob device with an encoder comprises a knob assembly 1 and an encoder 2, wherein the encoder 2 is mounted on a PCB board provided with a control circuit;

[0039] A circular protrusion 21 is provided on the top of the encoder 2 and extends upwards. The circular protrusion 21 is provided with a first fastening member 31.

[0040] The knob assembly 1 includes a rotating seat 11, which is hollow cylindrical and has a second fastening member 32.

[0041] The first fastening member 31 and the second fastening member 32 are engaged with each other.

[0042] The knob device of the present invention achieves a snap-fit connection between the knob assembly 1 and the encoder 2 by providing a circular protrusion 21 on the top of the encoder 2, equipping the circular protrusion 21 with a first snap-fit member 31, and providing a second snap-fit member 32 on the rotating base 11 of the knob assembly. This design enables the knob assembly 1 to be securely mounted on the encoder 2, ensuring the stability and reliability of the rotation operation.

[0043] The design of the annular protrusion 21 not only provides the basic structure for the snap-fit connection, but also guides the correct installation position of the knob assembly 1. The hollow cylindrical rotating seat 11 provides enough space for the knob assembly 1 to accommodate other functional components, such as a pressing member.

[0044] The cooperation between the first fastening member 31 and the second fastening member 32 realizes a quick and reliable connection between the knob assembly 1 and the encoder 2. This connection method facilitates assembly and disassembly while ensuring the firmness of the connection and avoiding the problem of loosening or falling off during use.

[0045] Through this structural design, the knob device achieves a tight integration of the knob assembly 1 and the encoder 2, ensuring both the accuracy and sensitivity of the rotation operation and improving the structural stability and service life of the entire device. This design also simplifies the assembly process and improves production efficiency.

[0046] Furthermore, a clamping groove is provided on the outer side wall of the annular protrusion 21. The clamping groove is formed by being recessed inward from the outer side wall of the annular protrusion 21. The clamping groove is the first fastening member 31.

[0047] The rotating seat 11 includes an outer ring 111 and an inner ring 112. The inner ring 112 is arranged inside the outer ring 111. The outer wall of the top of the inner ring 112 is connected to the inner wall of the outer ring 111. The inner ring 112 is provided with an elastic block, which is the second fastening member 32.

[0048] The inner ring 112 is sleeved on the outside of the annular protrusion 21 , and the elastic clamping block is connected in a cooperative manner with the clamping groove.

[0049] The outer wall of the annular protrusion 21 is provided with a snap-fitting groove as the first fastening member 31, which can provide a recessed structure for mating connection. The rotating seat 11 adopts a double-layer structure of an outer ring 111 and an inner ring 112, which enhances the overall strength. The inner ring 112 is provided with an elastic card block as the second fastening member 32, which can be flexibly matched with the snap-fitting groove. The inner ring 112 is sleeved on the outside of the annular protrusion 21, and the elastic card block is matched with the snap-fitting groove to achieve a reliable connection between the knob assembly and the encoder.

[0050] By providing a snap-in slot on the encoder's annular protrusion 21 and an elastic block on the inner ring 112 of the rotating base, and coupling the two together, the problem of a reliable connection between the knob assembly 1 and the encoder 2 is solved. The elastic block design makes the connection more flexible and reliable while not affecting the rotation function of the knob assembly 1. The double-layered ring structure enhances the strength of the rotating base 11, improving the stability and durability of the entire device. This design not only ensures a secure connection, but also facilitates assembly and disassembly and maintenance, improving the product's practicality and user experience.

[0051] Furthermore, the clamping groove is located at the lower part of the annular protrusion 21, the clamping groove is extended in the vertical direction, and the height of the clamping groove is smaller than the height of the annular protrusion 21;

[0052] The elastic block includes a fixed end 321 and a movable end 322. The movable end 322 is located above the fixed end 321. The lower portion of the fixed end 321 is connected to the inner ring 112. A protrusion is provided on the inner side of the movable end 322.

[0053] When the inner ring 112 is sleeved on the annular protrusion 21 , the protruding portion of the movable end 322 is locked in the locking groove.

[0054] The snap-fitting groove is located at the lower part of the annular protrusion 21, and the snap-fitting groove is extended in the vertical direction, but the height of the snap-fitting groove is less than the height of the annular protrusion 21, which is equivalent to the top of the snap-fitting groove not passing through the top of the annular protrusion 21. This makes it possible for the rotating component 1 to be installed from the top of the encoder 2 from top to bottom. When the inner ring 112 passes through a position where no snap-fitting groove is provided (the position at the upper part of the annular protrusion 21), the outer wall of the annular protrusion 21 squeezes the movable end 322 of the elastic clamp outward; when the inner ring 112 continues to move downward to a position where a snap-fitting groove is provided, the inner protrusion of the movable end 322 of the elastic clamp is clamped in the snap-fitting groove to achieve engagement. To further illustrate, since the snap-fitting groove is located in the middle and lower part of the annular protrusion 21, rather than vertically passing through the top of the annular protrusion 21, after the inner ring 112 of the rotating component is snap-fitted and installed on the annular protrusion 21 of the encoder, it is difficult for the rotating component 1 to separate from the encoder 2 in the vertical direction; and because the movable end 322 is elastic, the movable end 322 can be deformed outward by external force, so that the movable end 322 can be separated from the snap-fitting groove, thereby facilitating the disassembly and separation of the rotating component 1 and the encoder 2.

[0055] When the inner ring 112 is sleeved on the annular protrusion 21, the protrusion of the movable end 322 is snapped into the snap-in groove, which realizes a reliable connection between the knob assembly 1 and the encoder 2. At the same time, due to the elasticity of the movable end 322, it can also be easily disassembled when needed. This snap-in structure solves the connection problem between the knob assembly 1 and the encoder 2. By cleverly designing the position of the snap-in groove and the specific structure of the elastic card block, it achieves the dual purpose of stable connection and convenient disassembly. At the same time, because the snap-in point is located at the bottom (both the bottom of the rotating assembly 1 and the bottom of the encoder annular protrusion 21), it does not affect the rotation operation of the upper part, ensuring the normal function of the knob.

[0056] Furthermore, the outer side wall of the annular protrusion 21 is further provided with a guide positioning groove 22, which is recessed inward from the outer side wall of the annular protrusion 21. The guide positioning groove 22 extends in the vertical direction and is located at the upper part of the annular protrusion 21. The top of the guide positioning groove 22 passes through the top of the annular protrusion 21.

[0057] The inner side wall of the inner ring 112 is provided with a guide positioning block 113, and the guide positioning block 113 is extended in the vertical direction;

[0058] The guide positioning block 113 is cooperatively connected with the guide positioning groove 22 .

[0059] The guide slot 22 on the outer side of the annular projection 21 cooperates with the guide block 113 on the inner side of the inner ring 112 to guide the knob assembly 1 and encoder 2 during connection, ensuring accurate alignment and smooth connection. The guide slot 22 extends vertically through the top of the annular projection 21, allowing the guide block 113 to be inserted from the top, facilitating installation.

[0060] This guide and positioning structure, in conjunction with the previously mentioned snap-in slot and elastic block structure, enhances the connection stability between knob assembly 1 and encoder 2. The guide and positioning structure primarily serves to position and guide the knob, while the snap-in structure provides the securing force. Together, these two effectively prevent the knob assembly from shaking or falling off during use. Furthermore, precise guide positioning also enhances the precision and smoothness of rotational operation.

[0061] Furthermore, the number of the clamping grooves and the guiding and positioning grooves 22 is several, and the clamping grooves and the guiding and positioning grooves 22 are staggeredly distributed on the outer side wall of the annular protrusion 21;

[0062] There are a plurality of elastic clamping blocks and guide positioning blocks 113 , and the elastic clamping blocks and guide positioning blocks 113 are staggeredly distributed on the inner side wall of the inner ring 112 .

[0063] By providing a plurality of snap-in grooves and guide positioning grooves 22, and staggeredly distributing them on the outer wall of the circular protrusion 21, and staggeredly distributing a plurality of elastic snap blocks and guide positioning blocks 113 on the inner wall of the inner circular ring 112, the connection points between the knob assembly 1 and the encoder 2 can be increased, further enhancing the reliability of the connection and improving the stability of the connection.

[0064] The staggered distribution of multiple card slots and guide positioning slots 22, as well as the corresponding staggered distribution of elastic card blocks and guide positioning blocks 113, not only improves the connection strength, but also evenly disperses stress, reducing the risk of damage caused by excessive local force. At the same time, this structural design is also convenient for assembly and disassembly, and can achieve fast and accurate positioning and connection through multi-point coordination. In addition, this design also has good anti-torsion performance. The staggered distribution of multiple connection points can effectively resist the torsional force during the rotation process, ensure the relative position stability between the knob assembly and the encoder, and improve the accuracy and service life of the knob operation.

[0065] Furthermore, an annular protrusion 114 is provided on the inner side wall of the inner ring 112 along the circumference. The annular protrusion 114 is located above the elastic block. When the rotating seat 11 is sleeved on the annular protrusion 21, the bottom surface of the annular protrusion 114 fits with the top surface of the annular protrusion 21.

[0066] The inner sidewall of the inner ring 112 is provided with an annular protrusion 114. When the rotating base 11 is mounted on the annular protrusion 21 of the encoder, the bottom surface of the annular protrusion 114 fits against the top surface of the annular protrusion 21, forming a stable contact surface. This fitting structure reduces the shaking between the rotating base and the encoder, improving the stability of the entire knob device.

[0067] The annular protrusion 114 not only strengthens the connection between the rotating base 11 and the encoder 2, but also reduces relative movement between the components, thereby reducing wear. This structural design ensures that the knob device can maintain good stability and reliability during long-term use, extending the service life of the entire device.

[0068] Furthermore, the knob assembly 1 further includes a pressing member 12 and a knob cover 13. The pressing member 12 is disposed inside the rotating base 11, and the knob cover 13 covers the top opening of the rotating base 11. The upper portion of the pressing member 12 is detachably connected to the knob cover 13.

[0069] The encoder 2 is a hollow encoder, the PCB board is provided with a tact switch 4, the lower part of the pressing member 12 is accommodated in the hollow space of the encoder 2, and the bottom of the pressing member 12 faces the tact switch 4.

[0070] In another embodiment, the knob assembly 1 further includes a pressing member 12 and a knob cover 13, which implement the pressing function of the knob device. The pressing member 12 is disposed within the rotating base 11. The upper portion of the pressing member 12 is detachably connected to the knob cover 13. The lower portion of the pressing member 12 extends into the hollow interior of the encoder, and the bottom of the pressing member 12 faces the tactile switch 4 on the PCB board, so that the user can operate the pressing member 12 by pressing the knob cover 13, thereby triggering the tactile switch 4 and implementing the pressing function.

[0071] The detachable connection between the push member 12 and the knob cover 13 facilitates assembly and maintenance. The hollow encoder design provides space for the push member 12, making the overall structure more compact. The bottom of the push member 12 faces the tact switch 4, ensuring the accuracy and reliability of the pressing operation.

[0072] By integrating both rotation and push functions into a single knob, the encoder's rotational functionality is retained while also adding push functionality, enhancing the functionality and practicality of the knob. By combining this with a touch switch on the PCB, a wider range of control functions can be achieved to meet the needs of diverse application scenarios.

[0073] Furthermore, the upper side of the pressing member 12 is symmetrically provided with snap-fitting blocks 121 on both sides, and the bottom side of the knob cover 13 is symmetrically provided with snap-fitting rings 131 on both sides. The snap-fitting blocks 121 and the snap-fitting rings 131 are correspondingly connected in a one-to-one manner.

[0074] The snap-fit block 121 on the top of the pressing member 12 and the snap-fit ring 131 on the bottom of the knob cover 13 are connected by a snap fit, achieving a detachable connection between the pressing member 12 and the knob cover 13. The symmetrical arrangement of the two snap-fit blocks 121 and snap-fit rings 131 improves the stability and reliability of the connection between the pressing member 12 and the knob cover 13, preventing deformation or disengagement due to unilateral force.

[0075] It is further explained that when assembling the pressing member 12 and the knob cover 13, it is only necessary to align the snap block 121 with the snap ring 131 and press lightly to complete the connection; when disassembling, the two parts can be separated by applying appropriate force without the use of tools. The operation is simple and convenient, and the snap connection method facilitates quick assembly and disassembly.

[0076] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
