Description

Technical Field

[0001] This utility model belongs to the field of camera protection technology, specifically relating to a detachable and replaceable vehicle camera protection device and a vehicle camera. Background Technology

[0002] With the development of intelligent driving technology, in-vehicle cameras have become a core perception component of advanced driver assistance systems and autonomous driving, and their imaging quality directly affects the reliability of functions such as obstacle recognition and lane keeping. However, in areas with dense sandstorms, such as Xinjiang in China and the deserts of the Middle East, the camera lenses are continuously subjected to impacts from high-hardness particles while the vehicle is in motion.

[0003] Traditional cameras rely on hard coatings on the surface of optical glass lenses for protection. However, the adhesion between the hard coating and the glass substrate is limited. Under prolonged and continuous impact, scratches will appear, resulting in reduced light transmittance and blurred images. On gravel roads, large particles can directly penetrate the hard coating, causing permanent damage to the lens and increasing the false alarm rate of advanced driver assistance systems.

[0004] In addition, the lens of a traditional camera is integrated with the lens body. When the lens is worn, the whole thing needs to be replaced, and the replacement requires professional tools, which results in high maintenance costs and low after-sales efficiency.

[0005] While some fixed protective devices can prevent the impact of high-hardness particles, their low light transmittance and mismatch between curvature and lens optical path lead to image distortion, failing to meet the requirements of autonomous driving for high-definition imaging. Furthermore, their connection to the base often relies on a single clip or screw, which is prone to loosening under vehicle vibration, allowing sand and moisture to intrude and accelerating the aging of internal components. Utility Model Content

[0006] To overcome the problems of low light transmittance, image distortion, easy loosening of the protective device, and intrusion of sand and water vapor in the fixed protective device of the camera in the prior art, this utility model provides a detachable and replaceable vehicle camera protective device and vehicle camera.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] According to one objective of this utility model, a detachable and replaceable vehicle camera protective device is provided, comprising: a protective cover body, the protective cover body including a transparent front cover and a fixed rear cover, the bottom of the transparent front cover communicating with the top of the fixed rear cover to form a mounting cavity, a camera module being embedded into the mounting cavity from the bottom of the fixed rear cover, the lens end of the camera module corresponding to the transparent front cover, the fixed rear cover being detachably connected to the base of the camera module, and the curvature of the transparent front cover matching the optical path of the lens of the camera module.

[0009] In some alternative implementations, the outer wall of the base is provided with a first threaded structure, and the inner wall of the fixed rear cover is provided with a second threaded structure that matches the first threaded structure.

[0010] In some alternative implementations, the bottom of the transparent front cover extends a first locking plate radially away from the axis of the camera module, and the top of the fixed rear cover extends a second locking plate radially towards the axis of the camera module. The bottom of the transparent front cover and the top of the fixed rear cover are engaged by the first locking plate and the second locking plate.

[0011] In some alternative implementations, the top of the second card station is provided with a number of card slots arranged around the perimeter of all the second card stations.

[0012] In some alternative implementations, a first mounting platform is provided at the bottom of the base along the circumference of the base, and the bottom of the fixed rear cover abuts against the first mounting platform and is sealed and connected by a first sealing element.

[0013] In some alternative implementations, the surface of the first mounting platform is provided with an annular groove around the base, and the bottom of the fixed back cover extends a limiting platform in a radial direction away from the axis of the camera module. The bottom surface of the fixed back cover is provided with a limiting groove, the limiting platform is embedded in the annular groove, and is sealed to the first mounting platform by a first sealing member embedded in the limiting groove.

[0016] In some alternative implementations, a mounting bracket is also included, which is sleeved on the base. The outer wall of the mounting bracket is provided with a third thread structure, and the inner wall of the fixing cover is provided with a second thread structure that matches the third thread structure. The fixing cover and the mounting bracket are screwed together by the matching third thread structure and the second thread structure.

[0017] In some alternative implementations, a humidity regulating component is also included, wherein the outer wall of the lens end is provided with an annular groove, and the humidity regulating component is embedded in the annular groove.

[0018] According to another objective of this utility model, a vehicle-mounted camera is provided, including a camera module and a detachable and replaceable vehicle-mounted camera protective device as described in any of the above claims, wherein the camera module is embedded in the mounting cavity of the protective device and is detachably connected to the protective device.

[0019] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0020] This utility model provides a detachable and replaceable vehicle camera protection device.

[0061] Example 1

[0062] To overcome the problems of low light transmittance, image distortion, easy loosening of the protective device, and intrusion of sand and water vapor in the fixed protective device used in the prior art, this utility model provides a detachable and replaceable vehicle camera protective device.

[0063] This utility model provides a detachable and replaceable vehicle camera protection device, such as... Figures 1-4 As shown, it includes: a protective cover body 10, the protective cover body 10 includes a transparent front cover 11 and a fixed rear cover 12, the bottom of the transparent front cover 11 is connected to the top of the fixed rear cover 12 to form a mounting cavity, the camera module 20 is embedded into the mounting cavity from the bottom of the fixed rear cover 12, the lens end 21 of the camera module 20 corresponds to the transparent front cover 11, the fixed rear cover 12 is detachably connected to the base 22 of the camera module 20, and the curvature of the transparent front cover 11 matches the lens optical path of the camera module 20.

[0064] In this embodiment, the transparent front cover 11 can be made of impact-resistant transparent plastic or transparent glass, as long as it can transmit light without affecting the light path or light intensity.

[0065] In this preferred embodiment, the transparent front cover 11 and the fixed rear cover 12 are integrally formed. Therefore, in this embodiment, the fixed rear cover 12 and the transparent front cover 11 are made of the same material.

[0066] In this embodiment, the bottom of the transparent front cover 11 and the top of the fixed rear cover 12 are integrally formed. Since the fixed rear cover 12 is detachably connected to the base 22 of the camera module 20, the protective cover body 10 and the camera module 20 are detachably connected. This allows the camera module protective device of this embodiment to be quickly disassembled and replaced with the camera module 20, while also ensuring the stability of the connection between the camera module protective device and the camera module 20. By setting the curvature of the transparent front cover 11 to match the lens optical path of the camera module 20, the optical interference of the transparent front cover 11 to the lens is minimized, thereby ensuring that the light entering the lens propagates along the original design path, avoiding image distortion and blurring caused by the refraction angle deviation of the transparent front cover 11, improving the light transmittance, reducing the distortion rate, improving the imaging quality of the camera module 20, and ensuring that the recognition accuracy of the advanced driver assistance system for obstacles, lane lines, etc. is not affected.

[0067] This embodiment is a preferred embodiment, and the connection structure between the fixed rear cover 12 and the camera module 20 has been optimized.

[0068] In this embodiment, the outer wall of the base 22 is provided with a first threaded structure 221, and the inner wall of the fixed rear cover 12 is provided with a second threaded structure 121 that matches the first threaded structure 221. The fixed rear cover 12 and the base 22 are screwed together by the matching first threaded structure 221 and second threaded structure 121.

[0069] In this embodiment, the fixed back cover 12 is fixed to the base 22 by screwing, so that the fixed back cover 12 can be detached from the camera module 20, thereby making the protective cover body 10 replaceable.

[0070] In addition, a first mounting platform 222 is provided around the bottom of the base 22, and the bottom of the fixed cover 12 abuts against the first mounting platform 222 and is sealed and connected by the first sealing member 30.

[0071] Therefore, the bottom of the fixed rear cover 12 is sealed to the base 22 to form a sealed space between the protective cover body 10 and the camera module 20, which can reduce the risk of fogging and water ingress of the camera module 20 in environments such as vehicle wading and high temperature and humidity.

[0072] Preferably, the surface of the first mounting platform 222 is provided with an annular groove 223 around the base 22, and the bottom of the fixed back cover 12 extends a limiting platform 122 in the radial direction away from the axis of the camera module 20. The limiting platform 122 is embedded in the annular groove 223 to ensure the stability of the connection between the fixed back cover 12 and the base 22.

[0073] Furthermore, a limiting groove 123 is provided on the bottom surface of the fixed rear cover 12, and the first sealing member 30 is embedded in the limiting groove 123 to limit the installation position of the first sealing member 30. The bottom surface of the fixed rear cover 12 is sealed to the first mounting platform 222 through the first sealing member 30 embedded in the limiting groove 123, further ensuring the sealing effect between the protective cover body 10 and the camera module 20.

[0074] In addition, the bottom surface of the fixed back cover 12 is sealed with the base 22 through the first sealing element 30, which also plays a role in preventing slippage, further ensuring the stability of the screw connection between the fixed back cover 12 and the base 22.

[0075] In this embodiment, the first sealing element 30 is an annular element made of silicone, rubber or fluoropolymer.

[0076] Preferably, the camera module protection device of this embodiment further includes a humidity regulating component 50. The outer wall of the lens end 21 is provided with an annular groove 211, and the humidity regulating component 50 is embedded in the annular groove 211 to ensure the stability of the humidity regulating component 50 installation.

[0077] The humidity regulating component 50 is a humidity control sheet or humidity control adhesive made of moisture-absorbing material.

[0078] In this embodiment, a humidity regulating component 50 is installed in the sealed space formed between the protective cover body 10 and the camera module 20 to absorb water vapor in the sealed space and stabilize the humidity in the sealed space at a low level. This prevents the lens of the camera module 20 from fogging due to temperature and humidity changes, ensuring that the camera module 20 can image clearly and enabling the advanced driver assistance system to identify road conditions normally and clearly.

[0079] Furthermore, the humidity regulating component 50 absorbs moisture that intrudes into the sealed space, preventing short circuits, rust, and mold growth in the internal electronic and optical components of the camera module 20 due to moisture. This extends the lifespan of the camera module 20 and reduces the cost and hassle of repairing or replacing internally damaged components. Simultaneously, it maintains a relatively stable microenvironment within the camera module 20, minimizing the impact of temperature and humidity fluctuations on optical performance. Whether exposed to high temperatures followed by sudden rain or experiencing large temperature differences between the inside and outside of the vehicle in extremely cold regions, this helps the lens of the camera module 20 maintain good imaging performance, ensuring the reliable operation of autonomous driving-related functions.

[0080] Example 2

[0081] This utility model embodiment provides a detachable and replaceable vehicle camera protection device, which optimizes the structure of the protective cover body 10 and the connection structure between the protective cover body 10 and the camera module 20 based on embodiment 1.

[0082] In this embodiment, the transparent front cover 11 and the fixed rear cover 12 of the protective cover body 10 are designed as separate units.

[0083] like Figures 5-8 As shown, the connection structure between the transparent front cover 11 and the fixed rear cover 12 in this embodiment is as follows:

[0084] The bottom of the transparent front cover 11 extends a first locking platform 111 along the radial direction away from the axis of the camera module 20. The top of the fixed rear cover 12 extends a second locking platform 124 along the radial direction of the camera module 20 towards the axis of the camera module 20. The bottom of the transparent front cover 11 and the top of the fixed rear cover 12 are engaged by the first locking platform 111 and the second locking platform 124.

[0085] In this embodiment, the transparent front cover 11 and the fixed back cover 12 are designed as separate units by snapping the bottom of the transparent front cover 11 to the top of the fixed back cover 12.

[0086] In addition, in this embodiment, the transparent front cover 11 can be made of impact-resistant transparent plastic or transparent glass, as long as it allows light to pass through without affecting the light path or light intensity. The fixed rear cover 12 can be made of the same material as the transparent front cover 11, or it can be made of conventional plastic or metal. This embodiment does not limit the material of the fixed rear cover 12.

[0087] The sealing structure between the transparent front cover 11 and the base 22 in this embodiment is as follows:

[0088] A second mounting platform 224 is provided on the top surface of the base 22 along the circumference of the base 22. The bottom of the transparent front cover 11 abuts against the second mounting platform 224 and is sealed and connected by the second sealing member 40.

[0089] Therefore, the bottom of the transparent front cover 11 is sealed to the base 22 through the second sealing member 40, thereby forming a sealed space between the transparent front cover 11 and the base 22, and the humidity regulating member 50 is located in the sealed space to absorb the water vapor in the sealed space.

[0090] Furthermore, an annular limiting groove can be provided on the surface of the second mounting platform 224 to limit the second seal 40.

[0091] In this embodiment, the second sealing element 40 is an annular element made of silicone, rubber or fluoropolymer.

[0092] The connection structure between the fixed rear cover 12 and the base 22 in this embodiment is the same as that in Embodiment 1, specifically:

[0093] The outer wall of the base 22 is provided with a first threaded structure 221, and the inner wall of the fixed rear cover 12 is provided with a second threaded structure 121 that matches the first threaded structure 221. The fixed rear cover 12 and the base 22 are screwed together by the matching first threaded structure 221 and second threaded structure 121. This allows the fixed rear cover 12 to be detached from the camera module 20, thereby enabling the replacement of the protective cover body 10.

[0094] The base 22 has a first mounting platform 222 along its circumference. The bottom of the fixed cover 12 abuts against the first mounting platform 222 and is sealed by the first sealing member 30.

[0095] In this embodiment, the first sealing element 30 is an annular component made of silicone, rubber, or fluoropolymer. The first sealing element 30 further optimizes the sealing performance of the connection between the fixed rear cover 12 and the base 22, while also providing anti-slip properties, further ensuring the stability of the screw connection between the fixed rear cover 12 and the base 22.

[0096] In this preferred embodiment, the top of the second card holder 124 is provided with a plurality of card slots 125 arranged around the circumference of all the second card holders 124, which facilitates the removal of the fixed rear cover 12 using tools such as wrenches. Therefore, in this embodiment, only the transparent front cover 11 needs to be replaced, thus saving costs.

[0097] Example 3

[0098] This utility model embodiment provides a detachable and replaceable vehicle camera protection device, which optimizes the connection structure between the protective cover body 10 and the camera module 20 based on embodiment 2.

[0099] In this embodiment, the transparent front cover 11 and the fixed rear cover 12 of the protective cover body 10 are designed separately, and the connection structure between the transparent front cover 11 and the fixed rear cover 12 is the same as that in embodiment 2. This embodiment will not repeat the description.

[0100] In this embodiment, as Figures 9-12 As shown, the vehicle-mounted camera protection device also includes a mounting bracket 60, which is sleeved on the base 22. The outer wall of the mounting bracket 60 is provided with a third thread structure 61, and the inner wall of the fixed rear cover 12 is provided with a second thread structure 121 that matches the third thread structure 61. The fixed rear cover 12 and the mounting bracket 60 are screwed together by the matching third thread structure 61 and second thread structure 121.

[0101] Therefore, in this embodiment, the camera module 20 is completely placed inside the vehicle camera protection device, and the base 22 of the camera module 20 is fixedly connected to the bottom of the mounting bracket 60. The camera module 20 is installed on the vehicle body through the mounting bracket 60.

[0102] The sealing connection structure between the transparent front cover 11 and the fixed rear cover 12 and the mounting bracket 60 is the same as the connection structure between the transparent front cover 11 and the fixed rear cover 12 and the base 22 in Embodiment 2, specifically as follows:

[0103] A third mounting platform 62 is provided at the bottom of the mounting bracket 60, and a fourth mounting platform 63 is provided at the top of the mounting bracket 60. The bottom of the transparent front cover 11 abuts against the surface of the fourth mounting platform 63 and is sealed and connected by the second sealing member 40, so that a sealed space is formed between the transparent front cover 11, the mounting bracket 60 and the camera module 20. The bottom of the fixed rear cover 12 abuts against the fourth mounting platform 63 and is sealed and connected by the first sealing member 30.

[0104] In this embodiment, the material selection of the first seal 30 and the functions implemented by the second seal 40 are the same as those in Embodiment 2, and will not be repeated in this embodiment.

[0105] Furthermore, in this embodiment, the material selection for the transparent front cover 11 and the fixed rear cover 12 is the same as described in Embodiment 2, and will not be repeated here. The mounting bracket 60 in this embodiment can be made of the same material as the fixed rear cover 12.

[0106] Preferably, the mounting bracket 60 can be made of conventional plastic or metal. In this embodiment, the material of the mounting bracket 60 is not limited.
