Description

Technical Field

[0001] This invention relates to the field of vehicle camera technology, specifically to a backup lens type camera. Background Technology

[0002] In fields such as intelligent monitoring, autonomous driving, and industrial inspection, reliable imaging by camera sensors places extremely high demands on environmental adaptability. Under adverse weather conditions such as rain, fog, strong light, and nighttime, imaging systems face multiple challenges: for example, in foggy environments, suspended particles in the atmosphere strongly scatter visible light, leading to decreased image contrast and blurred details; in rainy scenes, polarized light reflected from the water surface can easily cause image overexposure, interfering with target recognition; and at night or under strong light, the drastic changes in spectral distribution make it difficult for traditional fixed filters to balance the signal acquisition needs of different wavelength bands.

[0003] Existing technologies primarily employ fixed filters or single-function filters. For example, while conventional infrared cutoff filters can suppress infrared interference under normal lighting conditions, they cannot address scattering issues in foggy weather. Polarizers, although reducing reflections, can cause signal loss in non-reflective environments. These fixed filters cannot dynamically adjust spectral transmittance according to real-time environmental conditions, leading to decreased image quality and increased algorithm misjudgment rates. Furthermore, some devices use manual filter replacement for optimization, but this method lacks real-time response and suffers from operational complexity and the potential for contamination, failing to meet the all-weather, automated requirements of intelligent sensing systems. Therefore, a filter switching technology with adaptive spectral adjustment capabilities is urgently needed to improve the reliability and adaptability of imaging systems in complex environments. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a backup lens-type camera, which solves the technical problem that existing vehicle cameras cannot intelligently switch lenses according to the external environment. It uses a switchable filter to automatically adjust the spectral transmittance according to the weather to adapt to the usage needs of different weather conditions.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A backup lens type camera includes a camera body, a backup lens is provided on the side of the camera body, and a lens replacement component is installed on the camera body. The lens replacement assembly includes an outer frame, a flip frame, a lens mounting base, a first drive assembly, a second drive assembly, and a third drive assembly. The outer frame is rotatably connected to the camera body, the flip frame extends into the outer frame and is rotatably connected to the outer frame, and the lens mounting base is slidably connected to the flip frame. The first drive assembly drives the outer frame to rotate along the axis of the camera body, the second drive assembly drives the flip frame to rotate, and the third drive assembly drives the lens mounting base to slide along the flip frame.

[0006] Furthermore, the first drive assembly includes a rotating frame gear ring, a motor gear, and a first motor. The rotating frame gear ring is fitted around the outside of the camera body, the first motor is located on one side of the outer frame, and the motor gear is fixed at the output end of the first motor. The motor gear meshes with the rotating frame gear ring.

[0007] Furthermore, the second drive assembly includes a worm gear, a worm, a mating gear, and a lateral movement assembly. The worm gear is fixed to the rotating shaft of the tilting frame, the worm is rotatably connected to the outer frame, the worm meshes with the worm gear, the mating gear is connected to the worm, and the lateral movement assembly drives the first motor to move.

[0008] Furthermore, the traverse assembly includes a second motor and a ball screw. The second motor is fixed to the outer frame, the ball screw is fixed to the output end of the second motor, and the nut of the ball screw is fixed to the first motor.

[0009] Furthermore, the third drive assembly includes a third motor and a threaded rod. The third motor is fixed to the top of the flip frame, and the threaded rod is fixed to the output end of the third motor. The threaded rod passes through the lens mounting base.

[0010] Furthermore, a magnet is fixedly connected to the outside of the spare lens, an electromagnet is fixedly connected inside the lens mounting base, and a limiting groove adapted to the spare lens is provided on the outside of the camera body.

[0011] Furthermore, the camera body has multiple planes on its outer side, and different spare lenses are set on different sides of the camera body.

[0012] Furthermore, the spare lens includes one or more of a polarizer, an infrared cutoff plate, and an infrared filter.

[0013] By employing the above technical solution, the present invention provides a backup lens type camera, which has at least the following beneficial effects: 1. This invention uses a lens replacement component that triggers a lens switching mechanism based on external environmental signals. This process requires no manual intervention and can automatically complete lens replacement according to changes in the environment such as light and focal length. It can intelligently switch lenses according to the external environment and uses switchable filters to automatically adjust the spectral transmittance according to the weather to adapt to different weather conditions.

[0014] 2. This invention, through the use of electromagnets and magnetic plates, enables the camera to replace lenses multiple times, flexibly adjusting the lens required by the camera when weather conditions change, thus meeting the need to replace lenses in response to changing weather conditions.

[0015] 3. This invention features high transmission precision and stable torque through gear meshing and worm gear and worm wheel transmission, ensuring the accuracy of the rotating and moving mechanism of the flip frame and preventing lens misalignment. Electromagnetic adsorption replaces the traditional groove design, using the electromagnetic force between the magnetic sheet and the lens mounting base to quickly fix the lens, reducing mechanical wear and installation errors. Simultaneously, the first motor reverses to reset the flip frame, and the threaded rod drives the spare lens into the camera body, forming an automated closed-loop process of "positioning-installation-reset," effectively shortening lens replacement time and improving equipment efficiency and lifespan.

[0016] 4. The present invention uses a first motor to drive the flip frame to rotate and attach to the side of the camera body, so that the lens replacement structure of the entire camera only increases the thickness of the flip frame, reducing the overall volume of replacing the lens of the vehicle camera and making it more convenient to adapt to miniaturized use scenarios.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 To automatically change the camera lens when weather conditions change, ensuring clear images even in foggy or rainy weather, please refer to [reference needed]. Figures 1-3 This embodiment proposes a backup lens type camera, including a camera body 1, a backup lens 2 provided on the side of the camera body 1, and a lens replacement assembly 3 installed on the camera body 1. The lens replacement assembly 3 includes an outer frame 31, a flip frame 32, a lens mounting base 33, a first drive assembly 34, a second drive assembly 35, and a third drive assembly 36. The outer frame 31 is rotatably connected to the camera body 1, the flip frame 32 extends into the outer frame 31 and is rotatably connected to the outer frame 31, and the lens mounting base 33 is slidably connected to the flip frame 32. The first drive assembly 34 drives the outer frame 31 to rotate along the axis of the camera body 1, the second drive assembly 35 drives the flip frame 32 to rotate, and the third drive assembly 36 drives the lens mounting base 33 to slide along the flip frame 32.

[0021] When the lens of the camera body 1 needs to be replaced in foggy or rainy weather, the first drive assembly 34 drives the outer frame 31, the flip frame 32, and the lens mounting base 33 to rotate coaxially along the camera body 1 until the outer frame 31, the flip frame 32, and the lens mounting base 33 move to the corresponding spare lens 2. Then, the first drive assembly 34 and the second drive assembly 35 cooperate to flip the entire flip frame 32. When the spare lens 2 is exactly inside the lens mounting base 33, the first drive assembly 34 and the second drive assembly 35 stop moving. The lens mounting base 33 electromagnetically attracts the spare lens 2. Then, the first drive assembly 34 and the second drive assembly 35 drive the flip frame 32 to rotate. Reversing the rotation, the flipping frame 32 drives the entire lens mounting base 33 to reset, and then the third drive component 36 is activated, driving the lens mounting base 33 and its internal spare lens 2 into the camera body 1 to complete the lens replacement. This significantly improves the adaptability of the device in different scenarios, such as strong light, low light, and macro shooting, ensuring the stability of shooting quality. The lens switching mechanism is triggered by external environmental signals. This process does not require manual intervention and can automatically complete the lens replacement according to changes in the environment such as light and focal length. It can intelligently switch lenses according to the external environment and uses switchable filters to automatically adjust the spectral transmittance according to the weather to adapt to the usage needs of different weather conditions.

[0022] In order to enable the camera to replace different spare lenses as needed, refer to Figure 1 and Figure 2The first drive assembly 34 includes a rotating frame gear ring 341, a motor gear 342, and a first motor 343. The rotating frame gear ring 341 is fitted around the camera body 1. The first motor 343 is located on one side of the outer frame 31. The motor gear 342 is fixed to the output end of the first motor 343 and meshes with the rotating frame gear ring 341. The second drive assembly 35 includes a worm gear 351, a worm 352, a mating gear 353, and a transverse movement assembly 354. The worm gear 351 is fixed to the rotating shaft of the tilting frame 32. The worm 352 is rotatably connected to the outer frame 31 and meshes with the worm gear 351. The mating gear 352... 53 is connected to the worm gear 352. The transverse component 354 drives the first motor 343 to move. The transverse component 354 includes a second motor 3541 and a ball screw 3542. The second motor 3541 is fixed on the outer frame 31. The ball screw 3542 is fixed at the output end of the second motor 3541. The nut of the ball screw 3542 is fixed to the first motor 343. The third drive component 36 includes a third motor 361 and a threaded rod 362. The third motor 361 is fixed on the top of the flip frame 32. The threaded rod 362 is fixed to the output end of the third motor 361. The threaded rod 362 passes through the lens mounting base 33.

[0023] The motor gear 342 meshes with the rotating frame gear ring 341. When it is necessary to rotate the entire outer frame 31, the first motor 343 drives the motor gear 342 to rotate, causing the motor gear 342 to rotate along the rotating frame gear ring 341. The motor gear 342 drives the entire outer frame 31 to rotate until the flipping frame 32 rotates to the position of the corresponding spare lens 2. Then, the first motor 343 stops working, and the second motor 3541 drives the first motor 343 and the motor gear 342 to move through the ball screw 3542 until the motor gear 342 meshes with the mating gear 353. At this time, the second motor 3541 stops working, and the first motor 343 restarts, driving the mating gear 3542. 3. Rotation, in conjunction with gear 353, drives the flip frame 32 to rotate via worm gear 352 and worm wheel 351. The flip frame 32 gradually approaches the camera body 1 until the spare lens 2 is inside the lens mounting seat 33. The lens mounting seat 33 electromagnetically attracts the spare lens 2. The first motor 343 drives the flip frame 32 to reverse, resetting the flip frame 32. Then the first motor 343 stops working. The third motor 361 drives the lens mounting seat 33 and the spare lens 2 inside it to slide along the flip frame 32 via threaded rod 362 until the lens mounting seat 33 and the spare lens 2 inside it move into the camera body 1, completing the process of replacing the lens of the camera.

[0024] Example 2 In order to enable the camera to replace lenses multiple times, refer to Figures 1-3Based on Embodiment 1, a magnet 4 is fixedly connected to the outside of the spare lens 2, an electromagnet 5 is fixedly connected inside the lens mounting base 33, a limiting groove adapted to the spare lens 2 is provided on the outside of the camera body 1, multiple planes are provided on the outside of the camera body 1, and the spare lenses 2 provided on different sides of the camera body 1 are different. The spare lens 2 includes one or more of polarizers, infrared cut-off sheets and infrared filters.

[0025] When the camera lens needs to be replaced, the first drive assembly 34, the second drive assembly 35, and the third drive assembly 36 move the lens mounting base 33 to the side of the camera body 1 where there is no spare lens 2. The electromagnet 5 stops supplying power, causing the spare lens 2 on the lens mounting base 33 to automatically fall into the limiting groove on the outside of the camera body 1. Then, the first drive assembly 34, the second drive assembly 35, and the third drive assembly 36 move the lens mounting base 33 to the spare lens 2 that needs to be replaced. Power is supplied to the electromagnet 5. Due to the magnetic attraction between the electromagnet 5 and the magnetic piece 4, the lens mounting base 33 electromagnetically attracts the spare lens 2, attracting the spare lens 2 on the outside of the camera body 1 into the lens mounting base 33. Finally, the first drive assembly 34, the second drive assembly 35, and the third drive assembly 36 move the lens mounting base 33 and the spare lens 2 inside it into the camera body 1. When the camera lens needs to be replaced again, the above process is repeated, enabling the camera to replace the lens multiple times. This allows for flexible adjustment of the lens required by the camera when weather conditions change, meeting the needs of lens replacement in changing weather conditions.

[0026] The gear meshing and transmission of the worm gear 352 and worm wheel 351 have the characteristics of high transmission accuracy and stable torque, which can ensure the accuracy of the rotation and movement of the flip frame 32 and avoid lens misalignment. The electromagnetic adsorption replaces the traditional groove design, and the lens is quickly fixed by the electromagnetic force of the magnetic piece 4 and the lens mounting seat 33, reducing mechanical wear and installation errors. At the same time, the first motor 343 reverses to reset the flip frame 32 and the threaded rod 362 drives the spare lens 2 into the camera body 1, forming an automated closed-loop process of "positioning-installation-reset", which effectively shortens the lens replacement time and improves the working efficiency and service life of the equipment.

[0027] When the lens does not need to be replaced, the first motor 343 drives the flip frame 32 to rotate and attach to the side of the camera body 1, so that the lens replacement structure of the entire camera only increases the thickness of the flip frame 32, reducing the overall volume of replacing the vehicle camera lens and making it more convenient to adapt to miniaturized usage scenarios.
