Description

Technical Field

[0001] The invention relates to the technical field of lenses, and in particular to an integrated lens with an anti-vibration and impact structure. Background Art

[0002] Integrated lenses are widely used in ships and unmanned equipment due to their high integration, compact structure and high reliability. The vibration and impact generated by the hull during operation can easily cause damage to shipborne electronic equipment. On the one hand, the work and operation of the ship itself will generate vibrations. On the other hand, in order to achieve the best effect, the lens is generally installed high outside the cabin and directly exposed to the air outside the cabin. When the ship encounters a complex external environment during navigation, factors such as wind resistance will cause the integrated lens to vibrate. Vibration may cause the position of the lens assembly to shift, resulting in image blur or distortion, or affect the accuracy of the focusing system, reducing the image quality. When long-term vibration accumulation damages internal devices, it will cause wear on internal mechanical components and damage internal circuits, affecting the normal operation of the lens.

[0003] In order to reduce the harm caused by vibration, a vibration damper is usually installed at the installation site of the lens to absorb the impact caused by vibration. However, the existing vibration damper has a poor vibration attenuation effect after installation. When the vibration amplitude is large, the vibration impact will still be transmitted to the inside of the lens, affecting the imaging quality and even greatly reducing the service life of the lens.

The connecting base plate is U-shaped and has a sliding block inside. The pressure plate is fixedly connected to the upper sides of the sliding block. The sliding block is T-shaped and its two ends slide in the cavity formed by the connecting base plate and the pressure plate.

[0014] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. As mentioned throughout the specification and claims, "including" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of implementing the present application, but the description is for the purpose of illustrating the general principles of the present application, and is not used to limit the scope of the present application. The scope of protection of the present application shall be determined by the definition of the attached claims.

[0015] like Figure 1-6As shown, it includes an integrated machine housing 1, a rotating base 2 and a fixed bracket 3. The bottom of the rotating base 2 is rotatably connected to a rotating disk 22. The bottom of the rotating disk 22 is connected to the fixed bracket 3 by bolts. The lower end of the fixed bracket 3 is provided with a plurality of fixing holes 31. The rotating base 2 and the integrated machine housing 1 can be fixed by bolts through the fixing holes 31. The rotating base 2 is a U-shaped structure. The integrated machine housing 1 is installed inside the rotating base 2 and can rotate along the circumference of the rotating base 2. The rotating disk 22 can drive the rotating base 2 to rotate 360°, and the shooting direction can be adjusted to increase the monitoring range. Both sides of the integrated machine housing 1 are fixedly connected with A rotating shaft 23 is rotatably connected to the side wall of the rotating base 2. A pitch motor 21 is installed on one side of the rotating base 2. The output end of the pitch motor 21 is fixedly connected to the rotating shaft 23. The pitch motor 21 can drive the integrated machine housing 1 to rotate along the rotating shaft 23. The pitch angle can be adjusted by driving the integrated machine housing 1 to rotate by the pitch motor 21 to shoot in different directions. A lens body 4 is arranged inside the integrated machine housing 1. A heat dissipation hole 11 is provided at the left end of the integrated machine housing 1 for dissipating heat from the lens body 4. A buffer device 5 is fixedly connected to the bottom of the lens body 4. The lower end of the buffer device 5 is fixedly connected to the integrated machine housing 1 below it.

[0016] The buffer device 5 includes a connecting bottom plate 51, a sliding block 52, a pressing plate 53 and a buffer block 54. The connecting bottom plate 51 is U-shaped and has a sliding block 52 disposed therein. The pressing plate 53 is fixedly connected to the upper sides of the sliding block 52. The sliding block 52 is T-shaped and its two ends slide in a cavity formed by the connecting bottom plate 51 and the pressing plate 53. The pressing plate 53 is fixedly installed on the upper side of the connecting bottom plate 51 by bolts. The sliding block 52 inside it is limited by the pressing plates 53 on both sides so that the sliding block 52 can slide between the pressing plate 53 and the connecting bottom plate 51. Buffer blocks 54 are connected to both ends of the connecting bottom plate 51. The length of the buffer block 54 is the same as the width of the connecting bottom plate 51. The buffer block 54 is made of silicone with a hardness range of 40HA to 50HA. A plurality of balls 56 are disposed inside the connecting bottom plate 51. The balls 56 are disposed on the outer side of the sliding block 52 and are located in the gap formed between the sliding block 52 and the connecting bottom plate 51 and the pressing plate 53. When the sliding block 52 is subjected to vibration impact, it moves inside the connecting base plate 51. The ball bearing 56 limits the movement of the sliding block 52 so that the sliding block 52 can only move along its length direction. At the same time, the ball bearing 56 can reduce the friction force when the sliding block 52 moves, so that the sliding block 52 moves more smoothly and avoids the movement blockage caused by foreign matter such as dust entering the connecting base plate 51. During the movement of the sliding block 52, the buffer block 54 will be squeezed. The buffer block 54 is elastic and is compressed after being squeezed to absorb vibration impact and reduce the impact force on the lens body 4, thereby protecting the lens body 4. Connecting plates 55 are provided on both sides of the connecting base plate 51. The lower ends of the connecting plates 55 are fixedly connected to the surface of the connecting base plate 51. The connecting plates 55 are respectively arranged on the outer sides of the two buffer blocks 54 to limit the buffer blocks 54. The buffer blocks 54 are arranged between the connecting base plate 51 and the connecting plates 55 to provide support for the buffer blocks 54 when they are squeezed, so that the buffer blocks 54 can be compressed under force.

[0017] like Figure 3 As shown, in order to improve the impact resistance of the lens body 4, a plurality of vibration-damping blocks 12 are filled between the side wall of the integrated housing 1 and the lens body 4. The vibration-damping blocks 12 are made of silicone material. The vibration-damping blocks 12 are arranged between the lens body 4 and the integrated housing 1 to absorb vibration when impacted, and also protect the electronic and mechanical components inside the lens body 4.

[0018] The principle of the present invention is as follows: a buffer device 5 is arranged below the lens body 4, and the buffer device 5 includes a connecting base plate 51 and a sliding block 52. When subjected to external vibration impact, the sliding block 52 slides inside the connecting base plate 51, and the ball 56 limits the movement of the sliding block 52, so that the sliding block 52 can only move along its length direction. At the same time, the ball 56 can reduce the friction when the sliding block 52 moves. The sliding block 52 will squeeze the buffer block 54 during the movement. The buffer block 54 is elastic and is compressed after being squeezed to absorb vibration impact, reduce the impact force on the lens body 4, and play a role in protecting the lens body 4. A plurality of vibration-damping blocks 12 are arranged between the lens body 4 and the integrated machine housing 1. The vibration-damping blocks 12 can absorb the vibration transmitted from the integrated machine housing 1 to the lens body 4, and protect the electronic and mechanical components inside the lens body 4.

[0019] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0020] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
