Description

Technical Field

[0001] This utility model relates to the field of automotive camera technology, specifically to dual roof-mounted cameras. Background Technology

[0002] Surveillance cameras are semiconductor imaging devices with advantages such as high sensitivity, resistance to strong light, low distortion, small size, long lifespan, and vibration resistance.

[0003] Most car cameras are installed at the rear of the car. However, this limits the camera's ability to observe the surrounding environment. Therefore, cameras are sometimes installed on the roof of the car. But when the weather is hot, rain can get on the camera's surface, affecting its ability to observe the surrounding environment. This can prevent the driver from accurately assessing the situation around the car. Therefore, it is necessary to install a waterproof structure for the camera.

[0004] Meanwhile, most existing car cameras are set up as a single camera, and a single camera provides limited information about the environment around the vehicle. Therefore, a dual-camera system on the roof is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-camera system for vehicles. By setting up a wiper assembly and a water-blocking assembly, the camera installed inside the camera mounting cover is protected from water and wiped to ensure that the camera can be used normally in rainy weather. The system is equipped with two sets of cameras, a first camera and a second camera, which work together to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The roof-mounted dual camera includes a camera mounting cover, a first camera, a second camera, and a wiper assembly for wiping rainwater off the surfaces of the first and second cameras. The first and second cameras are respectively disposed inside the camera mounting cover, and the wiper assembly is disposed above the camera mounting cover.

[0008] The wiper assembly includes a support rod, a wiper blade, and a drive module for driving the support rod to wipe away rainwater from the surfaces of the first and second cameras. The outer end of the support rod is fixedly installed with the wiper blade, and the inner end of the wiper blade is slidably connected to the lens sidewalls of the first and second cameras, respectively.

[0009] The front side of the first and second cameras is also provided with a water-blocking component for protecting the first and second cameras from rain.

[0010] Preferably, the drive module includes a mounting bracket, a servo motor, and a threaded rod. The mounting bracket is fixedly mounted on the surface of the camera mounting cover.

One end of the threaded rod passes through the side wall of the mounting bracket and is keyed to the output shaft of the servo motor. Another end of the threaded rod is fixedly mounted on the inner wall of the other end of the mounting bracket via a bearing seat. A movable seat is threaded onto the outer arc surface of the threaded rod, and the movable seat is fixedly mounted to the end of the support rod.

[0011] Preferably, a guide rod is fixedly disposed above the threaded rod between the inner walls of both sides of the mounting bracket, and the movable seat is slidably sleeved on the outer arc surface of the guide rod.

[0012] Preferably, the servo motor is further provided with a protective cover on the side wall of the mounting bracket for protecting the servo motor, and the bottom surface of the protective cover has a plurality of heat dissipation holes for dissipating the heat generated by the servo motor during operation.

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] The roof-mounted dual camera includes a camera mounting cover 1, a first camera 4, a second camera 5, and a wiper assembly 2 for wiping rainwater off the surfaces of the first camera 4 and the second camera 5. The first camera 4 and the second camera 5 are respectively disposed inside the camera mounting cover 1, and the wiper assembly 2 is disposed above the camera mounting cover 1.

[0028] The wiper assembly 2 includes a support rod 12, a wiper blade 13, and a drive module for driving the support rod 12 to drive the wiper blade 13 to wipe away rainwater from the surfaces of the first camera 4 and the second camera 5. The outer end of the support rod 12 is fixedly installed with the wiper blade 13, and the inner end of the wiper blade 13 is slidably connected to the lens sidewalls of the first camera 4 and the second camera 5 respectively.

[0029] A water-blocking component 3 for protecting the first camera 4 and the second camera 5 from rain is also provided on the front side of the second camera 5.

[0030] By providing a wiper assembly 2 above the camera mounting cover 1, and having a drive module inside the wiper assembly 2 for moving the wiper blade 13 horizontally, the wiper blade 13 is driven by the drive module to wipe away rainwater from the outer lens surfaces of the first camera 4 and the second camera 5 installed inside the camera mounting cover 1. This ensures that the wiper blade 13 removes rainwater adhering to the lens surfaces of the first camera 4 and the second camera 5 while the car is in motion, ensuring the normal use of the first camera 4 and the second camera 5, without affecting the driver's observation of the surrounding environment and causing personal safety issues.

[0031] The drive module includes a mounting bracket 6, a servo motor 8, and a threaded rod 10. The mounting bracket 6 is fixedly mounted on the surface of the camera mounting cover 1. The servo motor 8 is fixedly mounted on the outer side wall of one side of the mounting bracket 6. One end of the threaded rod 10 passes through the side wall of the mounting bracket 6 and is keyed to the output shaft of the servo motor 8. One end of the threaded rod 10 is fixedly mounted on the inner wall of the other end of the mounting bracket 6 through a bearing seat. A movable seat 11 is threadedly sleeved on the outer arc surface of the threaded rod 10. The movable seat 11 is fixedly mounted to the end of the support rod 12.

[0032] A servo motor 8 drives the threaded rod 10 to rotate, and a movable seat 11 is threaded onto the outer side of the threaded rod 10. The movable seat 11 is fixedly installed with the support rod 12. At the same time, a guide rod 9 is fixedly installed above the threaded rod 10 between the inner walls of both sides of the mounting bracket 6. The movable seat 11 is slidably sleeved on the outer arc surface of the guide rod 9. The servo motor 8 is a JGA25-370 model. When the servo motor 8 starts and drives the threaded rod 10 to rotate, the movable seat 11 is driven to move along the outer arc surface of the guide rod 9 and the threaded rod 10, thereby causing the scraper 13 at the end of the support rod 12 to move horizontally. The scraper 13 then scrapes away the rainwater from the lens surfaces of the first camera 4 and the second camera 5, ensuring that the first camera 4 and the second camera 5 can be used normally in rainy weather. The rainwater falls onto the car roof through the scraper 13.

[0033] A protective cover 7 is also provided on the side wall of the mounting bracket 6 to protect the servo motor 8. The bottom surface of the protective cover 7 has multiple heat dissipation holes for dissipating the heat generated by the servo motor 8 during operation. The protective cover 7 is also provided on the outside of the servo motor 8 to protect the servo motor 8, and the bottom of the protective cover 7 has multiple heat dissipation holes, so as to protect the servo motor 8 from external rainwater entering the interior of the servo motor 8. At the same time, it also prevents external stones and other debris from flying towards the servo motor 8 during the car's operation and damaging the servo motor 8, thereby affecting the requirement of the scraper 13 to scrape the rainwater off the lens surface of the first camera 4 and the second camera 5.

[0034] The water-blocking assembly 3 includes a water-blocking plate 19 and a hydraulic lifting rod 20. The hydraulic lifting rod 20 is symmetrically arranged on both sides of the mounting frame 6 and is disposed on the surface of the camera mounting cover 1. The working ends of the hydraulic lifting rod 20 are fixedly installed with the water-blocking plate 19.

[0035] Furthermore, a liftable water deflector 19 is installed on the outside of the first camera 4 and the second camera 5. The water deflector 19 is raised and lowered by a hydraulic lifting rod 20. When the car is not moving, the hydraulic lifting rod 20 lowers the water deflector 19 to protect the first camera 4 and the second camera 5, preventing rainwater from accumulating on the surface of the first camera 4 and the second camera 5 and corroding the lenses of the first camera 4 and the second camera 5, thus affecting the service life of the first camera 4 and the second camera 5.

[0036] The camera mounting cover 1 has a through hole 15 inside, and the first camera 4 is installed inside the through hole 15. The two sides of the through hole 15 are symmetrically provided with round holes 16 inside the camera mounting cover 1. The second camera 5 is installed inside one of the round holes 16, and a sealing plug is provided inside the other round hole 16.

[0037] Below the first camera 4 and the second camera 5, on the bottom surface of the camera mounting cover 1, there is a bracket 17. Below the bracket 17, there is a bottom sealing plate 18 for encapsulating the bracket 17, the first camera 4 and the second camera 5. The bottom of the bottom sealing plate 18 is symmetrically provided with a locking block 14, which is fixedly installed to the outer vehicle roof.

[0038] The first camera 4 is installed inside a through hole 15 inside the camera mounting cover 1, and the second camera 5 is installed inside one of the round holes 16 inside the camera mounting cover 1. The first camera 4 observes the surrounding environment outside the vehicle, and the second camera 5 detects ambient light and transmits the collected video information to a wireless receiver located at the front of the vehicle via a wireless transmitter. The receiver transmits the video information to the in-vehicle display screen, so that the in-vehicle display screen will display the road conditions around the vehicle observed by the first camera 4 in real time. The second camera 5 will also feed back the detection data to the electronic rearview mirror based on the ambient light detection, so that the electronic rearview mirror will adjust its brightness accordingly.

[0039] Working principle: When the car is driving in rainy weather, the hydraulic lifting rod 20 drives the water baffle 19 to rise, and the servo motor 8 drives the threaded rod 10 to rotate, which in turn causes the moving seat 11 to move along the outer arc surface of the guide rod 9 and the threaded rod 10. During the repeated translation process, the scraper 13 repeatedly scrapes the rainwater off the lens surfaces of the first camera 4 and the second camera 5 to further ensure the performance of the first camera 4 and the second camera 5.

[0040] When the car is not in motion during rainy weather, the hydraulic lifting rod 20 lowers the water deflector 19 to protect the first camera 4 and the second camera 5 inside the camera mounting cover 1 from rain, preventing rainwater from accumulating on the lens surfaces of the first camera 4 and the second camera 5 for a long time and corroding the lenses, thus affecting the service life of the first camera 4 and the second camera 5.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
