Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted intelligent vision device technology, specifically an intelligent vision device with protective functions. Background Technology

[0002] In the patent application with publication number 201820752735.3, a lens and a housing are included. The lens has a first threaded portion at its tail end, and one end of the housing has a second threaded portion that is threadedly connected to the first threaded portion of the lens. One of the first threaded portion and the second threaded portion is an external threaded post and the other is a corresponding internal threaded hole. A spring-loaded member is also fitted on the external threaded post. When the external threaded post is screwed into the internal threaded hole, the two ends of the spring-loaded member elastically press against the external thread on the external threaded post and the internal thread of the internal threaded hole, respectively. The advantages are as follows: By setting an external threaded post and an internal threaded hole at the rear of the lens and the front of the housing respectively, and fitting a spring-loaded component on the external threaded post, when the external threaded post and the internal threaded hole are screwed together, the two ends of the spring-loaded component elastically press against the external thread on the external threaded post and the internal thread of the internal threaded hole respectively. Under the action of the spring-loaded component, the lens and the housing fit tightly together, avoiding the problem of decreased clarity of the vehicle camera caused by movement between the lens and the housing due to large vibrations of the vehicle body during driving. It also effectively avoids the problem of the vehicle camera becoming blurry due to small external forces caused by different placement of the vehicle camera. There is no need to improve the fit precision of the threads to improve the blurring phenomenon that occurs during the assembly process, reducing the difficulty of processing and manufacturing, effectively improving the assembly yield, and thus reducing the manufacturing cost of the vehicle camera.

[0003] In the prior art, including the aforementioned patents, it is not convenient to prevent sand and gravel from flying from the road surface during use, thus making it difficult to extend the service life of the device, and also making it difficult to provide protection and guarantee for the CMOS components and imaging effect inside the camera. Utility Model Content

[0004] The purpose of this invention is to provide a smart vision device with protective functions to solve the problem mentioned in the background art of not being able to provide protection for the camera body and its internal optical distance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A smart vision device with protective function, including a camera, a mounting ring fixedly disposed on the outer surface of the middle part of the camera, a mounting frame disposed on the outer side of the mounting ring, a mounting post fixedly disposed on the outer surface of the mounting ring, a rotating rod rotatably disposed on one side of the upper end of the mounting post, and a roller rotatably disposed on the other end of the rotating rod, the roller being located inside the mounting frame, a frame disposed on one side of the camera, and an outer lens disposed inside the frame, the outer lens being made of sapphire glass, a lens disposed inside the frame between the outer lens, and the surface of the lens being coated with a polarizing film.

[0006] Furthermore, a limit block is provided on the side of the mounting column away from the mounting frame. The limit block is used to limit the rotation angle of the rotating rod. Two rollers are symmetrically arranged along the center line of the rotating rod. A spring is fixedly installed between the rotating rod and the mounting column. A sliding groove is provided on the upper side of the interior of the mounting frame, and a sliding groove is provided below the sliding groove through the mounting frame.

[0007] Furthermore, a slider is slidably arranged inside the first slide groove, and the slider is shaped like a "door". A connecting rod is rotatably arranged on the side of the slider near the second slide groove, and a torsion spring is arranged between the connecting rod and the slider. The lower end of the connecting rod is located inside the second slide groove and is slidably connected to it.

[0008] Furthermore, a second spring is fixedly installed on one side of the slider outside the mounting frame, and the other end of the second spring is fixedly connected to the mounting frame. An elastic component is fixedly installed inside the mounting frame on the side away from the camera, and a pressure block is fixedly installed on the other end of the elastic component. The pressure block is slidably connected to the mounting frame. The elastic component consists of a telescopic rod and a spring located outside it.

[0009] Furthermore, two outer lenses are symmetrically arranged along the center line of the frame. A rotating shaft is fixedly provided on both sides of the lens, and the rotating shaft is rotatably connected to the frame. A connecting plate is provided on one side of the rotating shaft inside the frame, and the connecting plate is connected to all the rotating shafts.

[0010] Furthermore, a magnet is fixedly installed on one side of the lower end of the connecting plate, and an electromagnetic coil is installed on one side of the magnet. The lower end of the electromagnetic coil is fixedly connected to the frame. A photoresistor is fixedly installed on the outer side of the frame around the outer lens. The photoresistor is connected to the electromagnetic coil. When the photoresistor is exposed to strong light, its resistance decreases. At this time, the current through the electromagnetic coil increases, generating a magnetic field.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this intelligent vision device with protective function is reasonable and has the following advantages:

[0012] (1) With the help of the coordinated operation of the mounting frame and rotating rod and other related components, the device can effectively cope with different sizes of impact force. When the impact force is relatively small, the device can quickly reset and continue to work normally by means of its own elastic structure, such as the clever cooperation between spring one and rotating rod. When subjected to a large impact force, its unique design allows the shock absorption stroke to be extended. For example, the process of the roller entering the rear half of the mounting frame and pushing the connecting rod effectively disperses and buffers the strong impact force. In addition, due to the presence of spring two, the device will not rebound quickly, cleverly avoiding secondary damage to the device due to external force during the rebound process, which greatly improves the stability and reliability of the device in complex impact environment.

[0013] (2) During the daily driving process of the vehicle, the photoresistor and the electromagnetic coil work together; the photoresistor can adjust its resistance value according to the intensity of external light; the current in the electromagnetic coil changes with the intensity of light, thereby generating magnetic fields of different magnitudes; when the intensity of external light is strong, the lens can effectively reduce the amount of light entering the camera, thereby ensuring the quality of the image; at the same time, the polarizing film on the lens can polarize the light, so that the laser cannot directly irradiate the CMOS component; this multi-protection mechanism builds a solid protective barrier for various optical components in the camera, greatly reducing the risk of damage caused by harsh external light environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 The present invention provides a technical solution as follows:

[0023] In this embodiment, a smart vision device with protective function includes a camera 1. The camera 1 has a mounting ring 2 fixedly disposed on its outer surface in the middle. A mounting frame 3 is disposed on the outer side of the mounting ring 2. A mounting post 201 is fixedly disposed on the outer surface of the mounting ring 2. A rotating rod 202 is rotatably disposed on one side of the upper end of the mounting post 201, and a roller 203 is rotatably disposed on the other end of the rotating rod 202. The roller 203 is located inside the mounting frame 3. A frame 4 is disposed on one side of the camera 1, and an outer lens 401 made of sapphire glass is disposed inside the frame 4. A lens 402 is disposed between the outer lens 401 inside the frame 4, and the surface of the lens 402 is coated with a polarizing film. The mounting frame 3 is a two-section design, with the front half tilted at 45° and the rear half at 10°, thus meeting different shock absorption requirements.

[0024] In this embodiment, a limiting block is provided on the side of the mounting post 201 away from the mounting frame 3. The limiting block is used to limit the rotation angle of the rotating rod 202. Two rollers 203 are symmetrically arranged along the center line of the rotating rod 202. A spring 204 is fixedly provided between the rotating rod 202 and the mounting post 201. A sliding groove 301 is provided on the upper side of the inside of the mounting frame 3, and a sliding groove 302 is provided below the sliding groove 301 through the mounting frame 3.

[0025] In this embodiment, a slider 303 is slidably disposed inside the first slide groove 301, and the slider 303 is configured in the shape of a "door". A connecting rod 304 is rotatably disposed on the side of the slider 303 near the second slide groove 302, and a torsion spring is disposed between the connecting rod 304 and the slider 303. The lower end of the connecting rod 304 is located inside the second slide groove 302 and is slidably connected thereto. The torsion spring is used to limit the position of the connecting rod 304 so that it is always perpendicular to the first slide groove 301.

[0026] In this embodiment, a second spring 305 is fixedly installed on one side of the slider 303 on the outside of the mounting frame 3, and the other end of the second spring 305 is fixedly connected to the mounting frame 3. An elastic component 306 is fixedly installed inside the mounting frame 3 on the side away from the camera 1, and a pressure block 307 is fixedly installed on the other end of the elastic component 306. The pressure block 307 is slidably connected to the mounting frame 3. The elastic component 306 consists of a telescopic rod and a spring located outside it. The cooperation between the first slide groove 301 and the elastic component 306 can prevent the roller 203 from directly hitting the mounting frame 3, thereby further reducing the force received by the camera 1.

[0027] In this embodiment, two outer lenses 401 are symmetrically arranged along the center line of the frame 4. A rotating shaft 403 is fixedly arranged on both sides of the lens 402, and the rotating shaft 403 is rotatably connected to the frame 4. A connecting plate 404 is arranged inside the frame 4 on one side of the rotating shaft 403, and the connecting plate 404 is connected to all the rotating shafts 403.

[0028] In this embodiment, a magnet 405 is fixedly installed on one side of the lower end of the connecting plate 404, and an electromagnetic coil 406 is installed on one side of the magnet 405. The lower end of the electromagnetic coil 406 is fixedly connected to the frame 4. A photoresistor 407 is fixedly installed on the outer side of the frame 4 around the outer lens 401. The photoresistor 407 is connected to the electromagnetic coil 406. When the photoresistor 407 is exposed to strong light, its resistance decreases. At this time, the current through the electromagnetic coil 406 increases, generating a magnetic field.

[0029] Working principle: When camera 1 is impacted, it will collapse inward. During this process, roller 203 rolls within the front half of mounting bracket 3. Simultaneously, rotating rod 202 unfolds under the impact force, and the external force is gradually offset by the elastic force of spring 204. Subsequently, under the restoring force of spring 204, rotating rod 202 retracts towards the center, causing camera 1 to quickly return to its initial position. If the external force on camera 1 is too great, roller 203 will enter the rear half of mounting bracket 3. During this period, the roller 203 needs to push the connecting rod 304 to rotate first. The torsion spring inside the connecting rod 304 will buffer the external force on the camera 1 to a certain extent. Then the roller 203 can enter the rear half of the mounting bracket 3. When the reset operation is performed, the roller 203 can drive the connecting rod 304 to slide down until it moves to the bottom and slides out from the second slide groove 302. In addition, when the connecting rod 304 slides, the second spring 305 can effectively prevent the camera 1 from rebounding too fast and ensure that the reset process is smooth.

[0030] In everyday use, the photoresistor 407 continuously receives signals from external light sources. Once the intensity of the external light source increases, the electromagnetic coil 406 generates a magnetic field under the influence of the changing current. This magnetic field causes the magnet 405 to move the connecting plate 404 upward, thereby causing the lens 402 to change its flip angle according to the light intensity. In this way, the polarizing film on the lens 402 can effectively reduce the light intensity received by the camera 1, while preventing the laser from directly irradiating the CMOS components inside the camera 1, thus ensuring the normal operation and image quality of the camera.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
