[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Please refer to ​ ;

[0032] In the manufacturing of encoders, different users have different requirements for the sound feedback emitted when the encoder shaft rotates. To meet this requirement, existing technology requires the manufacture of encoder parts with different structures using various molds to fit with the spring, resulting in high costs.

[0033] A general-purpose rotary encoder is designed to meet the sound feedback needs of different users at low cost. Specifically, it includes a spring 6 and a cover 2. Two positioning posts 51 and two positioning posts 52 are arranged diagonally inside the cover 2. The spring 6 has two positioning holes 7. The spring 6 is press-fitted with the positioning posts 51 or clearance-fitted with the positioning posts 52 through the positioning holes 7. It also includes a base 1 and a turntable assembly. The base 1 and the cover 2 are movably connected. The turntable assembly is located inside the base 1 and is rotatably connected to the base 1 and the cover 2. The turntable assembly includes a rotating shaft 9.

[0034] The positioning posts 51 and 52, which are diagonally arranged inside the cover 2, form a clever matching structure with the two positioning holes 7 on the spring piece 6, which significantly improves the ease of assembly and disassembly between the spring piece 6 and the cover 2. Specifically, the surface of the positioning post 52 is smooth and there is an appropriate gap between it and the positioning hole 7 of the spring piece 6, while the positioning post 51 is designed with an arc-shaped protrusion 8. The gap between the positioning post 52 and the positioning hole 7 allows the spring piece 6 to be easily inserted during assembly, and it can be separated without too much force during disassembly, thereby greatly improving the operational efficiency when maintaining or replacing parts and reducing the risk of component wear caused by frequent disassembly and assembly.

[0035] Furthermore, this structural design also brings significant differences in sound feedback when the turntable 9 rotates, making it suitable for users with different feedback needs;

[0036] When a user wants to hear a crisp sound while rotating the turntable 9, the positioning hole 7 of the spring 6 is fitted onto the smooth positioning post 52. Due to the gap, the slight collision between the spring 6 and the positioning post 52 during rotation will produce a crisp sound. In addition, the vibration amplitude of the contact part of the spring 6 and the peaks and troughs on the turntable 9 is relatively large, making it easier for the spring 6 and the turntable 9 to produce a crisp sound. This not only provides the user with clear feedback on the rotation status, but also makes the operation process more vivid and intuitive.

[0037] When a user wants to hear a dull sound while rotating the turntable 9, the positioning hole 7 of the spring 6 is fitted onto the positioning post 51 with the arc-shaped protrusion 8. First, the tight contact between the arc-shaped protrusion 8 and the inner wall of the positioning hole 7 eliminates the gap, thus buffering the collision during rotation. Second, the vibration amplitude of the contact part of the spring 6 and the peaks and troughs on the turntable 9 is smaller, thus producing a more dull sound. By producing both crisp and dull sounds, the different needs of different users for feedback sound can be met.

[0038] In addition, the cooperation between the positioning post 51 and the spring 6 ensures a firm connection between the cover 2 and the spring 6, while the addition of the arc-shaped protrusion 8 further enhances the positioning accuracy and anti-loosening ability. Even under long-term high-frequency use or external vibration, this structure can effectively avoid the phenomenon of spring 6 shifting or rotating parts jamming, thereby ensuring the high-precision measurement performance of the encoder and the reliability of long-term use.

[0039] In encoder assembly, the contact surfaces of the cover 2 and the base 1 in the prior art are both flat, and they are fixed by adhesive bonding between the flat surfaces. When the adhesive is poured, the adhesive may seep into the interior of the base 1, which may cause core components such as brushes or terminals to be contaminated or stuck by the adhesive, affecting contact performance and signal transmission reliability. It may even cause rotating parts to jam, thereby shortening the life of the encoder and reducing its measurement accuracy.

[0040] In this embodiment, a ring of steps 3 is provided on the upper end of the base 1, that is, steps 3 are provided on the upper part of each of the four side walls of the base 1, and the steps 3 are connected end to end. The connection between the steps 3 on two side walls is an arc-shaped step 3. The steps 3 are located near the central axis of the base 1. A ring of grooves 4 is provided on the lower end of the cover 2. The grooves 4 are adapted to the steps 3. The base 1 and the cover 2 are fixedly connected.

[0041] Specifically, when the operator applies adhesive between the base 1 and the cover 2, the adhesive will not cross the step 3 and enter the interior of the base 1 before it solidifies. The step 3, which is connected end to end, at the upper end of the base 1 and the groove 4 at the lower end of the cover 2, fits together to form a tight fitting structure, effectively preventing the adhesive from seeping into the interior of the base 1 during application. This avoids contamination or adhesion of core components such as brushes and terminals, thus ensuring the reliability of contact performance and signal transmission. The arc-shaped design at the connection of the step 3 further optimizes the sealing performance, reduces the risk of adhesive penetration, and enhances the connection strength between the base 1 and the cover 2, improving the stability and durability of the overall structure and ensuring that the encoder maintains high-precision measurement capabilities during long-term use.

[0042] Furthermore, the outer wall of step 3 is inclined, the groove wall of groove 4 is inclined, and the outer wall of step 3 abuts against the groove wall of groove 4.

[0043] The outer wall of step 3 and the groove wall of groove 4 are both inclined and abut against each other, which further enhances the tightness of the fit between base 1 and cover 2, forming a more effective sealing barrier. This can more effectively prevent the glue from seeping into the interior of base 1 during potting, protect the core components such as brush and terminal from contamination or adhesion, and ensure the stability of contact performance and signal transmission.

[0044] In this embodiment, a circular flange 10 is fixedly provided at the bottom of the base 1, the turntable 9 is located inside the base 1 and is rotatably connected to the base 1, and a circular flange 11 is fixedly provided at the bottom of the turntable 9. The inner wall of the circular flange 10 is rotatably connected to the outer wall of the circular flange 11. It is worth noting that there is a break in the circular flange 10.

[0045] When the turntable 9 rotates, the second circular flange 11 rotates relative to the first circular flange 10. The first circular flange 10 fixed at the bottom of the base 1 and the second circular flange 11 fixed at the bottom of the turntable 9 are connected by rotation of the inner and outer walls, which realizes the stable rotation of the turntable 9 in the base 1 and ensures the smoothness and concentricity of the rotation process.

[0046] Furthermore, the turntable 9 has a shaped groove 12 in the middle, and the turntable assembly also includes a rotating shaft 13. A shaped protrusion 14 is fixedly provided at the bottom of the rotating shaft 13. The shaped protrusion 14 is inserted into the shaped groove 12, realizing precise positioning and firm connection between the rotating shaft 13 and the turntable 9, ensuring that the torque can be transmitted efficiently during rotation and avoiding slippage or loosening. Furthermore, a ring of protrusions 18 is provided at the upper end of the groove wall of the shaped groove 12. The rotating shaft 13 is fixedly fitted with a rotating shaft ring. The inner wall of the rotating shaft ring and the shaped protrusion 14 form a circular groove 19. The circular groove 19 is engaged with the protrusion 18 to further improve the stability of the rotating shaft 13.

[0047] In this embodiment, a square through groove 15 is provided on the side wall of the cover 2, and a housing 16 is provided on the cover 2. The side wall of the housing 16 is engaged with the square through groove 15.

[0048] It is worth noting that a clearance hole is provided in the middle of the cover 2, and a bushing 17 is provided on the cover 2. The bushing 17 is connected to the clearance hole. The bushing 17 is fitted on the rotating shaft 13, which further improves the stability of the rotating shaft 13 and thus improves the accuracy of the encoder.

[0049] In this embodiment, the base 1 includes terminals. The terminals located outside the base 1 are bent into pins, and the terminals located inside the base 1 are raised to form brushes. During injection molding, the operator first puts the material strip with terminals into the mold cavity, and then removes the material strip after the mold is formed.
