Description

Technical Field

[0001] The utility model relates to the technical field of optical imaging equipment, in particular to a low-noise lens module. Background Art

[0002] In the field of photography and videography, the lens module plays a vital role. It is the core component of image capture and optical signal processing. The optical performance of the lens module directly determines key indicators such as the clarity, contrast, color reproduction and distortion of the image or video. With the rapid development of digital imaging technology, users' demand for high-quality images is increasing, which also puts higher requirements on the optical performance of the lens module. However, in addition to optical performance, modern users have also paid more and more attention to the overall user experience of photography and video equipment. Among them, operating noise, as an important non-optical performance indicator, has gradually become one of the important factors for users to evaluate the pros and cons of lens modules;

[0003] In traditional lens module design, there is often a lack of effective means of noise control. When the lens adjusts the focal length or performs other actions, it may generate obvious noise due to the movement of mechanical parts. This not only affects the user experience, but may also cause interference in certain noise-sensitive application scenarios. We have developed the following technologies and strategies:

[0004] 1. Silent driving mechanism:

[0005] Silent drive technologies such as stepper motors, ultrasonic motors or linear motors are used to replace traditional mechanical drive methods. These technologies usually have higher precision and lower noise levels.

[0006] 2. Shock absorption and seismic isolation design:

[0007] Add shock-absorbing materials or structures, such as rubber shock-absorbing pads, spring shock absorbers, etc., to the lens module to reduce the vibration and noise generated when the mechanical parts move.

[0008] 3. Precision machining and assembly:

[0009] By improving the processing accuracy and assembly quality of mechanical parts, the friction and collision between parts can be reduced, thereby reducing the generation of noise.

[0010] 4. Electronic noise suppression:

[0011] Use electronic noise suppression technology, such as Active Noise Control (ANC), to reduce or cancel noise electronically.

[0012] 5. Material and design optimization:

[0013] Choose low-noise materials, such as using coatings or materials with low coefficient of friction to reduce friction noise between components.

[0014] Optimize mechanical structure design and reduce unnecessary complex mechanisms and moving parts to reduce the possibility of noise generation.

[0015] 6. Intelligent noise management:

[0016] Integrate noise sensors and intelligent control systems to monitor noise levels in real time and adjust drive parameters through algorithms or take other measures to reduce noise.

[0017] 8. User experience oriented design:

[0018] The user experience is fully considered in the product design stage, and the noise control scheme is continuously optimized through user testing and feedback to ensure that the final product can meet the user's expectations for noise. To this end, a low-noise lens module is proposed. Utility Model Content

The inner side walls of the resistance ring 18 and the annular buffer pad 19 are slidably connected to the outer side wall of the sliding rod 12, and the sliding seat 13 on the lens body 14 slides along the sliding rod 12, thereby limiting the sliding seat 13, and then limiting the lens body 14, thereby increasing the stability of the movement of the lens body 14.

[0042] In one embodiment, specifically: a sound insulation tube 20 is fixedly connected to the inner wall of the protective inner shell 15 , and the sound insulation tube 20 is used to isolate the noise generated by the movement of the lens body 14 inside the protective inner shell 15 .

[0043] In one embodiment, specifically: the outer wall of the protective inner shell 15 is fixedly connected with sound insulation cotton 21, and the outer wall of the sound insulation cotton 21 is fixedly connected with the protective outer shell 22, and the noise generated by the movement of the lens body 14 inside the protective inner shell 15 is further isolated by the sound insulation cotton 21.

[0044] In one embodiment, specifically: a mounting hole 23 is opened at the center of the rear surface of the lens body 14, a sound insulation sleeve 24 is fixedly connected to the inner wall of the mounting hole 23, a reduction motor 25 is fixedly connected to the inner wall of the sound insulation sleeve 24, an output end of the reduction motor 25 is fixedly connected to an output shaft 26, a threaded column 27 is fixedly connected to the rear of the outer wall of the output shaft 26, a threaded hole 28 is opened at the center of the front surface of the base 11, the outer wall of the threaded column 27 is threadedly connected to the inner wall of the threaded hole 28, the noise generated by the reduction motor 25 during operation is effectively isolated by the sound insulation sleeve 24, the output shaft 26 is driven to rotate by the reduction motor 25, thereby driving the threaded column 27 to rotate inside the threaded hole 28, the threaded column 27 and the threaded hole 28 are threadedly connected, so that the threaded column 27 will move along the threaded hole 28 when rotating inside the threaded hole 28, and the threaded column 27 moves, thereby driving the output shaft 26 and the reduction motor 25 to move, and then driving the sound insulation sleeve 24 and the lens body 14 to move along the sliding rod 12.

[0045] In one embodiment, specifically: the front surface of the support ring 16 is fixedly connected to a ring-shaped sound insulation pad 29, and the outer side of the rear surface of the ring-shaped sound insulation pad 29 is fixedly connected to the front surface of the sound insulation cotton 21, so that the noise in front of the lens body 14 is effectively isolated by the ring-shaped sound insulation pad 29.

[0046] In one embodiment, specifically: an annular slot 30 is opened on the front surface of the protective shell 22, and a connecting ring 31 is fixedly connected to the inner wall of the annular slot 30, and a panel 32 is fixedly connected to the front surface of the connecting ring 31.

[0047] In one embodiment, specifically: a through hole 33 is opened at the center of the front surface of the panel 32, and a protective lens 34 is fixedly connected to the inner wall of the through hole 33. The protective lens 34 is transparent glass. The protective lens 34 protects the lens body 14, thereby preventing dust from entering the interior.

[0048] In one embodiment, specifically: the rear surface of the base 11 is fixedly connected to a circuit board 36 by a plurality of screws 35, and the circuit board 36 provides necessary circuit support and connection interface for the lens module, thereby realizing stable communication and data transmission functions with external devices.

[0049] When the utility model is working: when the lens module needs to adjust the position of the lens body 14 for focusing, the reduction motor 25 will start and drive the output shaft 26 to rotate. The rotation of the output shaft 26 will drive the threaded column 27 to rotate in the threaded hole 28 and move along its axial direction. Since the threaded column 27 is connected to the lens body 14 through the reduction motor 25 and the sound insulation sleeve 24, the movement of the threaded column 27 will drive the lens body 14 to slide along the slide rod 12. During the sliding process of the lens body 14, the sliding seat 13 will slide on the slide rod 12, thereby limiting the lens body 14 to ensure its movement stability. At the same time, the combined structure of the shock-absorbing spring 17, the resistance ring 18 and the annular buffer pad 19 can effectively absorb and buffer the vibration and impact force generated when the lens body 14 moves, thereby reducing the noise generated thereby. The use of sound insulation materials such as the sound insulation tube 20, the sound insulation cotton 21 and the annular sound insulation pad 29 further isolates the noise generated when the lens body 14 moves and the reduction motor 25 is running, so that the overall noise level of the lens module is greatly reduced.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
