[0004] In existing technology, encoders generate output commands by rotating through a twirling motion. However, due to the excessive rigidity of the encoder itself, it is easy for the encoder to become too noisy during later use, resulting in a short lifespan for the encoder. Utility Model Content

The support groove has a housing plate, the housing plate forms the support surface, the main shaft passes through the housing plate, the gasket is located between the housing plate and the clamping block, and the housing plate and the clamping block are respectively arranged in abutment with the gasket.

[0010] Furthermore, the encoding shaft includes a shaft seat block, which is fixedly arranged to the main shaft. The silicone ring is located between the housing plate and the shaft seat block, and the housing plate and the shaft seat block are respectively arranged to abut against the silicone ring.

[0011] Furthermore, the clamping block, the gasket, the seat plate, the silicone ring, and the bearing block are arranged in sequence and stacked, and the clamping block and the bearing block simultaneously clamp the gasket, the seat plate, and the silicone ring.

[0016] Compared with the prior art, the noise-reducing rotary encoder provided by this utility model allows the user to apply a rotational force to the knob module during use.

[0024] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0025] The low-noise rotary encoder includes an encoder shaft 1, a mount module 2, a knob module 3, a gasket 4, and a silicone ring 5. One end of the encoder shaft 1 is assembled with the mount module 2, and the other end of the encoder shaft 1 is movably assembled with the knob module 3. The knob module 3 is rotated relative to the mount module 2 under driving force. The mount module 2 includes an inner mount housing 21 and a support mount housing 22. The inner mount housing 21 and the support mount housing 22 are assembled or disassembled. The inner mount housing 21 is used to assemble with the scope body 6. The support mount housing 22 has a support surface. The gasket 4 is stacked with the support surface. The knob module 3 is in contact with the gasket 4. The silicone ring 5 is located between the encoder shaft 1 and the support mount housing 22, and the encoder shaft 1 and the support mount housing 22 are respectively in contact with the silicone ring 5.

[0026] In practical use, the user applies a rotational force to the knob module 3. Under the action of the encoder shaft 1, the knob module 3 rotates relative to the base module 2, thereby inputting commands. Since the knob module 3 and the support housing 22 clamp the abutment pad 4, and the encoder shaft 1 and the support housing 22 clamp the abutment silicone ring 5, the pad 4 acts as an isolation layer, preventing direct friction between parts and blocking sound transmission, thus reducing rotational noise. At the same time, the silicone ring 5 reduces the vibration transmission between parts and also improves the waterproofness of the structure, further reducing the noise during the use of the rotary encoder, achieving the effect of reducing noise, and also improving the service life of the rotary encoder.

[0027] The knob module 3 includes a locking block 31 and a support shell 32. The other end of the encoder shaft 1 is assembled with the locking block 31. The support shell 32 is fitted with the locking block 31, and the support shell 32 and the locking block 31 are assembled together; thus realizing the assembly of the encoder shaft 1 and the knob module.

[0028] The swivel support shell 32 has a swivel support column 321, the support base shell 22 has a support base groove, the gasket 4 is located in the support base groove, the support base groove forms the support shell surface, and the swivel support column 321 extends into the support base groove and is arranged in abutment with the gasket 4; in this way, the gasket 4 achieves isolation between the swivel support column 321 and the support base shell 22, and plays a role in reducing noise when rotating.

[0029] The swivel support column 321 has a support column groove, which is arranged in a ring and is recessed in the inward direction. The support shell 22 has a shell protrusion, which is arranged in a ring and is movably embedded in the support column groove. In this way, the assembly stability of the swivel support shell 32 is improved by the cooperation between the shell protrusion and the support column groove, and the rotational stability of the swivel support shell 32 is improved when rotating.

[0030] The encoder shaft 1 includes a clamping block 11 and a main shaft 12. The main shaft 12 passes through the clamping block 11 and is fixedly assembled with the clamping block 11. The support groove has a housing plate, which forms a support surface. The main shaft 12 passes through the housing plate. The gasket 4 is located between the housing plate and the clamping block 11, and the housing plate and the clamping block 11 are respectively arranged in abutment with the gasket 4.

[0031] In this way, under the action of the clamping block 11, the stability of the shim 4 is enhanced, the isolation effect of the shim 4 is guaranteed, and the cooperation effect between the shim 4 and the swivel support column 321 is guaranteed.

[0032] The encoder shaft 1 includes a shaft seat block 13, which is fixedly arranged to the main shaft 12. The silicone ring 5 is located between the housing plate and the shaft seat block 13, and the housing plate and the shaft seat block 13 are respectively arranged to abut against the silicone ring 5. This increases the contact area between the silicone ring 5 and the shaft seat block 13 and the housing plate, thereby improving the effect of the silicone ring 5 in reducing the vibration transmission between parts.

[0033] The spindle 12 passes through the silicone ring 5, and the outer surface of the spindle 12 is arranged in contact with the silicone ring 5. In this way, the spindle 12 can position and limit the displacement of the silicone ring 5, thereby improving the stability of the silicone ring 5.

[0034] The clamping block 11, the gasket 4, the seat plate, the silicone ring 5, and the bearing block 13 are arranged in sequence and stacked together. The clamping block 11 and the bearing block 13 simultaneously clamp the gasket 4, the seat plate, and the silicone ring 5. In this way, the sound reduction effect of the gasket 4 and the silicone ring 5 is improved, and the noise reduction effect is achieved.

[0035] The knob module 3 includes an outer cover 33, with a cover block formed in the middle of the outer cover 33. The cover block and the locking block 31 are assembled together, and the cover block is arranged correspondingly to the middle of the encoder shaft 1. Under the action of the outer cover 33, the locking block 31 is prevented from being exposed, and the outer cover 33 cooperates with the locking block 31 to make the setting of the encoder shaft 1 more stable.

[0036] The knob module 3 includes a main rotating shell 34 and an outer rotating cover 33 fastened to the main rotating shell 34. The main rotating shell 34 and the rotating support shell 32 are assembled together, and the rotating support shell 32, the encoder shaft 1, and the support shell 22 are respectively located inside the main rotating shell 34.

[0037] In this way, the main rotating shell 34 facilitates the setting of the rotating support shell 32, the encoder shaft 1, and the support shell 22, and also makes it easier for the user to apply rotational force.

[0038] The knob module 3 includes a knob cover ring 35, which is fitted onto the inner housing 21. The knob cover ring 35 is located inside the main housing 34 and is arranged in a ring shape. The knob cover ring 35 is in movable contact with the inner wall of the main housing 34. In this way, under the action of the knob cover ring 35, the rotation of the main housing 34 is supported and positioned, thereby improving the rotational stability of the main housing 34.

[0039] The knob cover ring 35 has a cover ring groove, which is arranged in a ring shape. The main rotating housing 34 has a locking hole 341, which is arranged in a through-hole. The locking hole 341 corresponds to and is connected to the cover ring groove. The locking rod extends through the locking hole 341 and is embedded in the cover ring groove. Under the action of the locking rod, the main rotating housing 34 is fixed, which limits the accidental rotation of the main rotating housing 34 and ensures the normal use of the scope. When it is necessary to operate the rotary encoder, the locking rod is first removed from the cover ring groove, and then a rotational force is applied to the main rotating housing 34.

[0040] The inner shell 21 has an inner shell groove, which is arranged in a ring and is recessed inward. The main shell 34 has a main shell strip, which is arranged in a ring and is protruding inward. The main shell strip is movably embedded in the inner shell groove. In this way, the rotational stability of the main shell 34 is improved by the cooperation of the main shell strip and the inner shell groove.
