Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to an optical lens vibration reduction device. Background Technology

[0002] With the widespread application of optical imaging technology in aerospace, vehicle navigation, security monitoring, field exploration, and industrial inspection, the working environment faced by optical lenses is becoming increasingly complex and variable, especially high-frequency and high-intensity vibration environments, which have become the norm. As a core component of precision optoelectronic systems, the imaging quality and operational stability of optical lenses directly determine the performance and reliability of the entire system.

[0003] In existing technologies, to ensure the structural stability and installation accuracy of optical lenses, a rigid connection method is commonly used to directly fix the lens to the optical housing or equipment mounting base. Specifically, the lens is rigidly connected to the housing via a threaded interface, pressure ring, or fasteners to form an integral structure. While this installation method can ensure the lens's position is fixed in static or low-disturbance environments, in actual use, especially under continuous mechanical vibration, impact, or complex environmental excitation, the following significant technical defects are exposed: 1. Due to the rigid contact between the lens and the housing, there is a lack of effective vibration isolation or buffering. Vibration energy generated by the external environment is transmitted directly to the lens body through the optical housing with almost no loss, making the lens susceptible to mechanical damage; 2. In a vibrating environment, the rigidly connected lens will vibrate along with the housing and the supporting equipment. This uncontrolled movement will cause a slight but high-frequency offset or jitter of the lens's optical axis, resulting in continuous changes in the light path entering the lens, thus leading to poor imaging stability and affecting optical performance.

[0004] Therefore, the rigid connection between the optical lens and the protective cover in the existing technology is no longer able to meet the increasingly stringent requirements of the vibration environment. Therefore, an optical lens vibration reduction device is needed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an optical lens vibration damping device. The optical lens body is mounted on a lens mounting plate using a lens clamping component. The lens mounting plate and rubber damping posts are fixed to an optical platform using screws. The rubber damping posts attenuate the vibration energy transmitted from the optical platform to the lens mounting plate, thereby reducing the vibration of the lens mounting plate and the lens body, and thus preventing damage and displacement of the optical lens.

[0006] This utility model is achieved through the following technical solution: providing an optical lens vibration reduction device, including an optical lens, a lens clamping component covering the top and sides of the optical lens, and a lens fixing plate located below the lens clamping component. A rubber vibration damping pad is provided between the bottom of the optical lens and the lens fixing plate. Multiple sets of vibration damping components are provided circumferentially at the bottom of the optical lens. The vibration damping components include screw fixing posts and rubber vibration damping posts arranged sequentially from the inside to the outside. A through hole is opened on the lens fixing plate, and the vibration damping components are located in the through hole.

[0007] As a preferred embodiment, the rubber damping column is a split design, including an upper damping column and a lower damping column that are arranged opposite each other on both sides of the through hole. The upper and lower damping columns have the same structure, each including a damping column body, a through hole opened along the axial direction of the damping column body, a first protrusion and a second protrusion on the damping column body, and the upper and lower damping columns are joined together through the second protrusion.

[0008] As a preferred embodiment, the lower surface of the first protrusion of the upper shock absorber is fitted to the upper surface of the lens mounting plate, and a groove is formed around the outside of the through hole on the surface of the lens mounting plate. The first protrusion of the lower shock absorber fits into the outer wall of the groove, and the lower surface of the first protrusion of the lower shock absorber protrudes from the lower surface of the lens mounting plate.

[0009] As a preferred embodiment, the bottom of the optical lens is provided with multiple sets of buffer components that are spaced apart from the shock-absorbing components. The buffer components include fasteners and rubber buffer blocks located between the fasteners and the bottom of the optical lens.

[0010] As a preferred embodiment, the fastener includes a clamping block and a fixing block. The clamping block and the rubber buffer block are connected together, and the fixing block is located on both sides of the fastener. The fixing block has a slot, and the bolt fixes the fastener to the optical platform through the slot.

[0011] As a preferred embodiment, the fixing post is fitted inside the rubber shock-absorbing post, and the screw is fitted inside the fixing post.

[0012] As a preferred option, a gasket is provided between the fixed column and the rubber shock-absorbing column.

[0013] As a preferred option, the optical lens is fixed to the lens clamping component by bolts.

[0014] The beneficial effects of this invention are as follows: The lens clamp mounts the optical lens onto the lens mounting plate, and screws secure the lens mounting plate and rubber shock-absorbing columns to the optical platform. The rubber shock-absorbing columns attenuate the vibration energy transmitted from the optical platform to the lens mounting plate, thereby reducing the vibration of the lens mounting plate and the main body, and thus preventing damage and displacement of the optical lens. The rubber shock-absorbing columns on both sides of the lens mounting plate simultaneously dampen the lens mounting plate, thereby improving the damping effect. The damping components arranged circumferentially along the lens mounting plate absorb vibration energy from all directions, thereby improving the damping effect. Attached Figure Description

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] This embodiment discloses an optical lens vibration reduction device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the system includes an optical lens 4, lens retainers 5 covering the top and sides of the optical lens 4, and a lens mounting plate 3 located below the lens retainers 5. An optical platform 1 is located below the lens mounting plate 3. To achieve vibration reduction, a rubber shock-absorbing pad 8 is provided between the bottom of the optical lens 4 and the lens mounting plate 3. Multiple sets of shock-absorbing components 2 are provided circumferentially on the bottom of the optical lens 4. The shock-absorbing components 2 include screws 6, fixing posts 203, and rubber shock-absorbing posts that are sequentially fitted together. The lens mounting plate 3 has through holes, and the optical platform 1 and the lens mounting plate 3 are connected together through the shock-absorbing components.

[0018] In this embodiment, the upper damping column 201 and the lower damping column 202 are two coaxially fixed cylindrical structures of different sizes. The inner diameters of the two cylinders are the same, but their outer diameters are different, and the outer diameter of the smaller cylinder is the same as the diameter of the through hole. Specifically, the rubber damping column is a split design, including an upper damping column 201 and a lower damping column 202 that are positioned opposite each other on both sides of the through hole. The upper damping column 201 and the lower damping column 202 have the same structure, such as... Figure 6 As shown, both the upper damping column 201 and the lower damping column 202 include a damping column body 205, a through hole 206 opened along the axial direction of the damping column body 205, a first protruding edge 207 and a second protruding edge 208 opened on the upper damping column body 205, and the upper damping column 201 and the lower damping column 202 are connected together through the second protruding edge 208. The lower surface of the first protruding edge of the upper damping column 201 is fitted to the upper surface of the lens mounting plate 3, and a groove is opened around the outside of the through hole on the lower surface of the lens mounting plate 3. The upper surface of the first protruding edge of the lower damping column 202 is fitted to the outer wall of the groove, and the lower surface of the first protruding edge of the lower damping column 202 protrudes from the lower surface of the lens mounting plate 3. This design lifts the lens mounting plate 3, and the screws 6 fix the damping assembly 2 to the optical platform 1. Through the damping column assembly, the lens mounting plate 3 carrying the optical lens 4 and the optical platform 1 form a flexible connection.

[0019] like Figure 5 As shown, the lens clamp 5 has a U-shaped structure. The lens clamp 5 encloses the optical lens 4 and is fixed to the lens mounting plate 3 with bolts. The lens clamp 5 mounts the optical lens 4 onto the lens mounting plate 3. The screws 6 pass through the through holes of the lens mounting plate 3 and the rubber shock-absorbing columns in sequence and are fixed to the optical platform 1. The lens mounting plate 3 and the optical platform 1 are flexibly connected through the rubber shock-absorbing columns. When the optical platform 1 vibrates, the rubber shock-absorbing columns attenuate the vibration energy transmitted from the optical platform 1 to the lens mounting plate 3. The vibration energy transmitted to the lens mounting plate 3 decreases, the vibration amplitude of the lens mounting plate 3 decreases, and the vibration amplitude of the optical lens 4 and the lens clamp 5 decreases.

[0020] In this embodiment, the shock absorption component 2 is arranged circumferentially along the lens fixing plate 3. After the optical platform 1 vibrates, the rubber shock absorption column attenuates the vibration energy transmitted from the optical platform 1 to the lens fixing plate 3, and the vibration energy transmitted to the lens fixing plate 3 from any direction is reduced.

[0021] like Figure 2 , 4 As shown, the bottom of the optical lens 4 is provided with multiple sets of buffer components 7 distributed at intervals with the shock-absorbing components 2. The buffer components 7 include fasteners 702 and rubber buffer blocks 701 located between the fasteners 702 and the lens fixing plate 3. Figure 8As shown, the fastener 702 includes a clamping block and a fixing block 704. The clamping block 703 and the rubber buffer block 701 are connected together. The fixing block 704 is located on both sides of the clamping block 703, and the fixing block 704 has a strip groove 705. The bolt fixes the fastener 702 to the optical platform 1 through the strip groove 705.

[0022] After the optical platform 1 vibrates, the rubber buffer block 701 attenuates the vibration energy transmitted from the optical platform 1 to the lens fixing plate 3, the vibration energy transmitted to the lens fixing plate 3 decreases, and the offset of the lens fixing plate 3 decreases.

[0023] In this embodiment, the rubber damping pad 8 is made of medium-hardness rubber. The rubber damping pad 8 attenuates the vibration energy transmitted from the lens fixing plate 3 to the optical lens 4, thus reducing the vibration energy transmitted to the optical lens 4 and reducing the vibration amplitude of the optical lens 4.

[0024] In this embodiment, the fixing post 203 is sleeved inside the rubber shock-absorbing post, and the screw 6 is sleeved inside the fixing post 203, such as... Figure 7 As shown, the fixing column 203 is also a hollow cylindrical structure, and a gasket 204 is provided between the upper end of the fixing column 203 and the rubber shock-absorbing column.

[0025] In this embodiment, the buffer assembly 7 is arranged around the periphery of the shock absorption device, which serves to limit and protect the optical lens module. When the vibration and impact intensity of the external environment exceeds the maximum range that the shock absorption assembly 2 can offset, and the displacement of the optical lens module is too large, the rubber buffer block 701 on the buffer assembly 7 will come into contact with the side of the lens fixing plate 3, thus providing protection for the optical lens module by limiting its position and reducing vibration.

[0026] In this embodiment, if the optical platform is in a vibrating environment, and the optical lens is performing a focusing operation at this time, the six sets of vibration damping components 2 and the rubber vibration damping pads 8 will absorb vibrations from all directions to reduce the harmful effects of environmental vibration on the focusing of the optical lens, so as to make the focus clear and ensure good optical effect.
