Description

Technical Field

[0001] This invention belongs to the technical field of vehicle-mounted radar protection equipment, specifically referring to a vehicle-mounted electronic radar anti-collision shell structure. Background Technology

[0002] As a core sensing component for intelligent driving, automotive radar is constantly exposed to the vehicle's exterior, facing complex conditions such as collisions, wind, sand, rain, and snow. Its outer casing must not only ensure the safety of the internal precision components but also maintain electromagnetic transparency to avoid affecting radar beam transmission and angle measurement accuracy. Existing casings often suffer from insufficient collision protection or structural design flaws, making them susceptible to damage in minor scratches or rear-end collisions. This leads to radar signal attenuation and beam distortion, directly impacting the stability of driver assistance systems. Therefore, there is an urgent need to optimize the outer casing's collision protection structure to balance protective performance and electromagnetic compatibility.

[0003] The cost of repairing and replacing automotive radar systems remains high. Repairing a single lidar unit is expensive, and replacing millimeter-wave radar can cost several thousand yuan. The core reason is the high degree of integration between the existing housing and the radar unit, coupled with a lack of targeted anti-collision design, requiring complete replacement even for minor damage. Furthermore, repairs rely on original equipment manufacturer (OEM) calibration equipment, and this technological monopoly further drives up costs. Frequent and expensive repairs significantly increase the cost of ownership for vehicle owners, hindering the widespread adoption of intelligent driving technology. Therefore, developing a housing structure that combines anti-collision properties with ease of maintenance is of significant practical importance. Summary of the Invention

[0004] In response to the above situation and to address the problems of easy damage and high maintenance costs of current vehicle-mounted radar after collisions, this invention provides a collision-resistant housing structure for vehicle-mounted electronic radar. This structure effectively avoids damage to existing vehicle-mounted radar modules after collisions. The protective device adopts a mechanical structure, resulting in low design, production, and installation costs. It uses a low-cost housing to protect the high-cost integrated components of the vehicle-mounted radar system, thus solving the problem of difficult maintenance of vehicle-mounted radar.

[0005] The technical solution adopted by this invention is as follows: This invention provides a vehicle-mounted electronic radar anti-collision housing structure, including a housing, a collision lateral movement and retraction structure, a vehicle-mounted radar module, a rotation limiting structure, and a probe closure and sealing protection device. The housing is fixedly installed on the car bumper by screws, and the front end of the housing is parallel to the outer wall of the car body shell. The collision lateral movement and retraction structure engages and slides within the housing. The vehicle-mounted radar module is fixed relative to the collision lateral movement and retraction structure and is engaged within the collision lateral movement and retraction structure. After a collision occurs, the collision lateral movement and retraction structure drives the vehicle-mounted radar module to move horizontally. The rotation limiting structure engages and connects with the collision lateral movement and retraction structure. The probe closure and sealing protection device engages and connects with the rotation limiting structure and is engaged within the housing.

[0006] Furthermore, the collision lateral retraction structure includes a radar collar, a lateral support, a protective lens, and a lens ring support. The radar collar is engaged and fixed on the vehicle radar module. The lateral support is fixedly installed on the outer wall of the radar collar. The lens ring support is fixedly connected to the lateral support. The protective lens is fixedly installed on the lens ring support.

[0007] Furthermore, the protective lens is made of chemically strengthened high-aluminosilicate glass, and the protective lens is designed as a convex arc-shaped cover plate structure.

[0008] Furthermore, the rotation limiting structure includes a threaded limiting post, a rotation adjusting gear, a gear outer sleeve, a limiting bracket, a positioning spring, and a bracket slot tube. A retaining ring is provided on the inner wall of the housing. The gear outer sleeve is rotatably engaged in the retaining ring. The rotation adjusting gear is fixedly connected to the gear outer sleeve. The threaded limiting post is engaged with the inner wall of the gear outer sleeve. A spherical protrusion is provided on the inner wall of the gear outer sleeve. The spherical protrusion slides along the threaded surface of the threaded limiting post. When the threaded limiting post is pressed and slid, the gear outer sleeve rotates by sliding along the threaded surface of the threaded limiting post via the spherical protrusion on its inner wall, thereby driving the rotation adjusting gear to rotate. The bracket slot tube is fixedly disposed on the inner wall of the housing. The limiting bracket is fixedly mounted on the threaded limiting post. The two ends of the positioning spring are respectively connected to the threaded limiting post and the bracket slot tube. The limiting bracket slides within the bracket slot tube.

[0009] Furthermore, the threads on the surface of the threaded limiting post are close to the direction of the rotary adjusting gear, and there is a section without threads at the connection between the threaded limiting post and the limiting bracket. This ensures that the probe closing and sealing protection device will only change its structure and protect the vehicle radar module after the vehicle radar module is hidden behind the probe closing and sealing protection device.

[0010] Furthermore, a sliding block is provided inside the bracket slot tube, and a positioning block is fixedly provided on the side wall of the limiting bracket. The sliding block slides horizontally inside the bracket slot tube, and a spring is provided between the sliding block and the bracket slot tube. After the positioning block enters the bracket slot tube, it will push the sliding block to move horizontally. After the two are misaligned, the sliding block restricts the spatial position of the positioning block. Both the sliding block and the positioning block are designed as triangular prism structures.

[0011] Furthermore, the threaded limiting post and the lens annular bracket are fixedly connected by a connecting plate.

[0012] Furthermore, the probe closure sealing protection device includes an annular housing, an adjusting ring, an arc-shaped rack, a shielding plate, and a limiting ring. The side wall of the annular housing is provided with small holes for mounting screws. The annular housing is fixed to the inner wall of the housing by screws. The adjusting ring engages and rotates within the annular housing. The arc-shaped rack is fixedly installed on the side wall of the adjusting ring. The shielding plate engages and slides within the annular housing. The limiting ring is fixedly installed on the inner wall of the annular housing. Rotating the arc-shaped rack can rotate the adjusting ring, further changing the position of the shielding plate within the annular housing, allowing the shielding plate to slide within the annular housing, thereby blocking the hole in the middle of the annular housing.

[0013] Furthermore, the arc-shaped rack is meshed with a rotary adjusting gear.

[0014] Furthermore, the annular housing has a sliding groove on its side wall, and the connection between the arc-shaped rack and the adjusting ring slides in the sliding groove.

[0015] Furthermore, the adjusting ring is provided with an arc-shaped groove, the limiting ring is provided with a strip-shaped groove, and small locking blocks are provided on both the front and rear surfaces of the shielding plate. The two sets of small locking blocks engage and slide in the arc-shaped groove and the strip-shaped groove, respectively.

[0016] Furthermore, the hardness of the front end of the housing is less than that of the protective lens and the lens ring bracket, and the hardness of the connection between the housing and the retaining ring is greater than that of the front end of the housing. After the front end of the housing is broken due to a car accident, the lens ring bracket is squeezed and moved backward, causing the vehicle radar module to move behind the probe closing and sealing protection device. The thread on the threaded limit post drives the rotating adjustment gear to rotate, the arc rack deflects, and the shielding plate slides, thereby shielding and protecting the vehicle radar module.

[0017] Furthermore, the annular housing has a sliding groove on its side wall, and the transverse support engages and slides in the sliding groove. To prevent the lens annular support from sliding arbitrarily while the vehicle is moving and has not encountered a collision, the transverse support and the sliding groove are connected by plastic heat fusion. The connection part is dotted to ensure that it can be disconnected after a collision without affecting the movement of the transverse support.

[0018] Furthermore, the front end of the housing is provided with a slot for engaging and installing a lens ring bracket. When the vehicle is not impacted, the lens ring bracket is engaged in the front end of the housing.

[0019] Furthermore, the threaded limiting post is provided with a straight groove, which is connected to a spiral groove on the surface of the threaded limiting post. The spherical protrusion inside the gear outer sleeve first slides along the straight groove, and then enters the threaded groove from the straight groove, thereby changing the rotation angle of the rotary adjusting gear.

[0020] This solution provides a vehicle-mounted electronic radar anti-collision housing structure, the benefits of which are as follows: (1) Effectively absorb collision impact and protect the core radar module: This application uses a collapsible housing and protective lens structure to cause the lens ring bracket and the lateral support bracket to move the vehicle radar module horizontally backward when the vehicle is involved in a collision, so that it can leave the direct impact area and enter the probe closed sealing protection device. This collision lateral shrinkage structure resolves the external impact force at the mechanical level, avoids the vehicle radar module from being directly damaged by force, thereby significantly improving the radar's survival rate in accidents and reducing damage to internal precision components caused by slight deformation of the housing. (2) Achieve low-cost shell protection for high-value radar and significantly reduce maintenance costs: The modular and detachable design makes the shell and radar body relatively independent. In the event of a collision, only the shell (such as the front end of the housing) is damaged, while the core vehicle radar module is protected by the dual protection of lateral movement and shield closure. Users only need to replace the shell components instead of the entire radar module, avoiding reliance on the original manufacturer's high repair and calibration costs, significantly reducing maintenance costs and time, and improving the product's economy and maintainability. (3) Automatic protection triggered after impact and status indication function: Through the linkage between the rotating limit structure and the probe closing sealing protection device, after the radar module moves to the rear position, the threaded limit column drives the rotating adjustment gear to rotate, which in turn drives the arc rack and the adjustment ring to move, so that the shielding plate automatically closes to form secondary protection. In addition, if the impact is light and the complete protection is not triggered, the positioning spring will push the structure part to reset and make the protective lens protrude from the damaged shell, intuitively reminding the user that the shell needs to be inspected or replaced, which has the dual function of automatic protection and visual warning.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] like Figures 1-9As shown, the present invention provides a vehicle-mounted electronic radar anti-collision housing structure, including a housing 1, a collision lateral retraction structure 2, a vehicle-mounted radar module 3, a rotation limiting structure 4, and a probe closure sealing protection device 5. The housing 1 is fixedly installed on the car bumper by screws. The collision lateral retraction structure 2 is engaged and slidable within the housing 1.

[0027] The collision lateral retraction structure 2 includes a radar collar 6, a lateral support 7, a protective lens 8, and a lens ring support 9. The radar collar 6 is engaged and fixed on the vehicle radar module 3. The lateral support 7 is fixedly set on the outer wall of the radar collar 6. The lens ring support 9 is fixedly connected to the lateral support 7. The protective lens 8 is fixedly installed on the lens ring support 9.

[0028] The protective lens 8 is made of chemically strengthened high-aluminosilicate glass, and the protective lens 8 is designed as a convex curved cover plate structure.

[0029] The rotating limiting structure 4 includes a threaded limiting post 10, a rotating adjusting gear 11, a gear outer sleeve 12, a limiting bracket 13, a positioning spring 14, and a bracket slot tube 15. A retaining ring 16 is provided on the inner wall of the housing 1. The gear outer sleeve 12 is engaged and rotatably installed in the retaining ring 16. The rotating adjusting gear 11 is fixedly connected to the gear outer sleeve 12. The threaded limiting post 10 is engaged and connected to the inner wall of the gear outer sleeve 12. A spherical protrusion is provided on the inner wall of the gear outer sleeve 12. The spherical protrusion slides along the threaded engagement of the threaded limiting post 10. The bracket slot tube 15 is fixedly installed on the inner wall of the housing 1. The limiting bracket 13 is fixedly installed on the threaded limiting post 10. The two ends of the positioning spring 14 are respectively connected to the threaded limiting post 10 and the bracket slot tube 15. The limiting bracket 13 engages and slides within the bracket slot tube 15.

[0030] The thread on the surface of the threaded limit post 10 is close to the direction of the rotary adjusting gear 11, and there is a section without threads at the connection between the threaded limit post 10 and the limit bracket 13.

[0031] The bracket slot tube 15 is provided with a sliding block 17, and the side wall of the limiting bracket 13 is fixedly provided with a positioning block 18. The sliding block 17 slides horizontally in the bracket slot tube 15, and a spring is provided between the sliding block 17 and the bracket slot tube 15. Both the sliding block 17 and the positioning block 18 are designed as triangular prisms.

[0032] The threaded limit post 10 and the lens ring bracket 9 are fixedly connected by a connecting plate.

[0033] The probe closure sealing protection device 5 includes an annular housing 19, an adjusting ring 20, an arc-shaped rack 21, a shielding plate 22, and a limiting ring 23. The side wall of the annular housing 19 is provided with small holes for mounting screws. The adjusting ring 20 is engaged and rotated inside the annular housing 19. The arc-shaped rack 21 is fixedly installed on the side wall of the adjusting ring 20. The shielding plate 22 is engaged and slids inside the annular housing 19. The limiting ring 23 is fixedly installed on the inner wall of the annular housing 19.

[0034] The arc-shaped rack 21 is meshed with the rotary adjusting gear 11.

[0035] The annular housing 19 has a sliding groove 24 on its side wall, and the connection between the arc-shaped rack 21 and the adjusting ring 20 slides in the sliding groove 24.

[0036] The adjusting ring 20 is provided with an arc-shaped groove 25, the limiting ring 23 is provided with a strip-shaped groove 26, and the front and rear surfaces of the shielding plate 22 are provided with small locking blocks 27. The two sets of small locking blocks 27 engage and slide in the arc-shaped groove 25 and the strip-shaped groove 26 respectively.

[0037] The hardness of the front end of the housing 1 is less than that of the protective lens 8 and the lens ring support 9, and the hardness of the connection between the housing 1 and the retaining ring 16 is greater than that of the front end of the housing 1.

[0038] The annular housing 19 has a sliding groove 28 on its side wall, and the transverse support 7 engages and slides in the sliding groove 28.

[0039] The front end of the housing 1 is provided with a slot for engaging and mounting the lens ring bracket 9.

[0040] The threaded limiting post 10 is provided with a straight groove 29, which is connected to the spiral-shaped groove on the surface of the threaded limiting post 10.

[0041] In practical use, the housing 1 is installed on the car bumper with screws. At this time, the protective lens 8 is parallel to the front end of the housing 1. The signal transmitting end of the vehicle radar module 3 is close to the protective lens 8, and the protective lens 8 will not affect the signal emitted by the vehicle radar module 3. When the vehicle is involved in a collision and the vehicle's shell is broken and damaged, the housing 1 is also damaged. The front end of the housing 1 is damaged, and the lens ring bracket 9 and the protective lens 8 are continuously subjected to external pressure during the vehicle impact. The transverse support 7 moves deeper into the housing 1, and the connection between the transverse support 7 and the slide 28 is broken. The transverse support 7 moves the vehicle radar module 3 through the radar collar 6, causing the vehicle radar module 3 to move to the rear of the annular housing 19. At the same time, the unthreaded part of the threaded limit post 10 and the limit support 13 move into the support slot tube 15. When the vehicle radar module 3 and the annular housing 19 are spatially misaligned, the spherical protrusion inside the gear outer sleeve 12 enters the thread groove from the straight groove 29 on the surface of the threaded limiting post 10. Due to the structural limitation of the limiting bracket 13 and the bracket slot tube 15, the threaded limiting post 10 will not rotate when it moves toward the bracket slot tube 15. Therefore, the gear outer sleeve 12, which is engaged with the retaining ring 16, rotates under the action of the spherical protrusion, driving the rotary adjusting gear 11 to rotate. When the rotary adjusting gear 11 rotates, the arc-shaped rack 21 rotates under meshing action, the adjusting ring 20 rotates inside the annular housing 19, the position of the arc-shaped groove 25 on the adjusting ring 20 changes, the two ends of the small block 27 slide along the strip groove 26 and the arc groove 25 respectively, and the shielding plate 22 shields the hole in the middle of the annular housing 19 to avoid external impact damage to the vehicle radar module 3; When the shielding plate 22 blocks the hole in the middle of the annular shell 19, the positioning block 18 and the sliding block 17 on the limiting bracket 13 slide out of position and then fix themselves to each other to prevent the shielding plate 22 from being unstable. When the external impact force is small, and the positioning block 18 does not contact the sliding block 17, the positioning spring 14 will push the threaded limit post 10 outward. In the case of a small impact force, the front end of the housing 1 is damaged, but the structure and shape of the protective lens 8 are unchanged. The protective lens 8 protrudes more than the damaged housing 1, indicating that a new housing 1 needs to be replaced. This application provides full protection for the high-cost vehicle radar module 3, reducing the probability of replacing the vehicle radar module 3 after a collision.
