Description

Technical Field

[0001] This utility model relates to the field of radar cover technology, specifically a multi-sealed radar cover for automobile roofs. Background Technology

[0002] The radar cover on the car roof is not only an "armor" protecting the internal LiDAR, cameras, and other precision sensors, but also effectively manages airflow and reduces wind resistance and noise. Its core strength lies in its superior signal transmission; made of high-performance engineering plastics with low dielectric constants (such as PC / PMMA), it ensures unobstructed sensor signal penetration for accurate environmental perception. It cleverly integrates cutting-edge technology with aerodynamics and vehicle aesthetics, making it a key exterior component for achieving advanced intelligent driving.

[0003] Traditional roof-mounted radar covers often employ a single-layer sealing structure or a simple sealing ring design, which has gradually revealed numerous limitations in practical applications. Once the seal fails, moisture, dust, or chemical contaminants can infiltrate, damaging the sensors and creating water mist or stains on the inside of the cover. This severely interferes with the transmission of optical and electromagnetic signals, thereby affecting the perception accuracy and functional safety of the intelligent driving system. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-seal automotive roof radar cover, which improves the stability of the cover body installation and also effectively improves the sealing performance between the cover body and the base plate, achieving the advantage of multi-seal effect and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-sealed car roof radar cover, comprising a radar connected to a cover body, a base plate at the bottom of the cover body, and a connecting mechanism for securely connecting the cover body and the base plate. The connecting mechanism includes two rotating shafts, multiple pressing blocks, and two conical teeth. The pressing blocks are connected to the rotating shafts and press against the cover body. The conical teeth are connected to the ends of the rotating shafts, and the two conical teeth are meshed together. The rotating shafts are connected to a driving mechanism for driving the rotating shafts to rotate. The cover body is provided with a sealing surface one, a sealing surface two, and a sealing surface three, which are pressed against the base plate.

[0006] Preferably, the connecting mechanism further includes a plurality of guide seats for guiding the rotation shaft.

[0007] Preferably, the guide seat is fixed to the base plate, the rotating shaft passes through multiple guide seats, and the rotating shaft is rotatably connected to the guide seats.

[0008] Preferably, the drive mechanism includes a rotating head, a rotating groove, a positioning bolt, a turbine, and a worm gear. The rotating head is used to drive the worm gear to rotate. The worm gear is connected to the turbine gear, which is connected to the end of the rotating shaft. The rotating groove is provided in the rotating head, and the positioning bolt is used to position the rotating head.

[0009] Preferably, the worm gear is rotatably connected to the base plate, and the bottom of the worm gear is connected to the rotating head.

[0016] 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.

[0017] Please see Figures 1 to 8 This utility model provides a multi-sealed car roof radar cover, including a cover body 1 and a radar 2 connected to the cover body 1. A base plate 3 is provided at the bottom of the cover body 1 and is fixedly connected to the roof. The base plate 3 is connected to a connecting mechanism for securely connecting the cover body 1 and the base plate 3. The connecting mechanism includes two rotating shafts 8, multiple pressing blocks 12, and two conical teeth 14. The pressing blocks 12 are connected to the rotating shafts 8 and press against the cover body 1. The conical teeth 14 are connected to the ends of the rotating shafts 8 and are meshed with each other, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio. That is, the rotation of the rotating shaft 8 can synchronously drive the other rotating shaft 8 to rotate. The rotating shaft 8 is connected to a driving mechanism for driving the rotating shaft 8 to rotate. The cover body 1 is provided with a sealing surface 9, a sealing surface 10, and a sealing surface 11, which are pressed against the base plate 3.

[0018] There are two connecting mechanisms, and correspondingly two driving mechanisms. When installing the cover plate body 1, the cover plate body 1 is connected to the base plate 3. The driving mechanism drives the rotating shaft 8 to rotate, which in turn drives the conical tooth 14 to rotate. The conical tooth 14 drives another conical tooth 14 to rotate, thereby rotating the other rotating shaft 8. This causes multiple pressing blocks 12 to rotate synchronously. The pressing blocks 12 press against the connecting groove 17 on the inner side of the cover plate body 1, applying downward pressure to the cover plate body 1, improving the stability of the cover plate body 1 installation, and making the operation simple and convenient.

[0019] The connecting mechanism also includes multiple guide seats 13, which guide the rotating shaft 8. The guide seats 13 are fixed to the base plate 3, and the rotating shaft 8 passes through the multiple guide seats 13, and the rotating shaft 8 is rotatably connected to the guide seats 13. The guide seats 13 can ensure the stability of the rotation of the rotating shaft 8, thereby improving the stability of the pressing block 12 rotation, so that the pressing block 12 can accurately press against the connecting groove 17 of the cover plate body 1.

[0020] The drive mechanism includes a rotating head 5, a rotating groove 6, a positioning bolt 7, a worm gear 15, and a worm 16. The rotating head 5 drives the worm gear 16 to rotate. The worm gear 16 is connected to the worm gear 15, which is connected to the end of the rotating shaft 8. The rotating groove 6 is located on the rotating head 5, and the positioning bolt 7 is used to position the rotating head 5. The rotating groove 6 has a regular polygonal structure. A tool is used to align with the rotating groove 6, and then the rotating head 5 is driven to rotate, which synchronously drives the worm gear 16 to rotate. The worm gear 16 drives the worm gear 15 to rotate, thereby realizing the rotation of the rotating shaft 8. The operation is flexible and convenient. Because the worm gear 15 and worm gear 16 have a self-locking function, the rotation of the rotating shaft 8 is prevented from rotating. Furthermore, because the car will experience some bumps during driving, in order to prevent the pressing block 12 from loosening, after the rotating head 5 rotates to the corresponding position, the positioning bolt 7 is used to lock and fix the rotating head 5, thereby limiting the worm gear 16 and effectively preventing the rotation of the rotating shaft 8. This provides a good limiting effect on the pressing block 12, thereby improving the stability of the cover body 1 during installation.

[0021] The worm 16 is rotatably connected to the base plate 3, and the bottom of the worm 16 is connected to the rotating head 5, which improves the rotational stability of the worm 16. The guide seat 13 guides the rotating shaft 8, making the turbine 15 rotate stably and ensuring the transmission effect between the worm 16 and the turbine 15.

[0022] The positioning bolt 7 is threadedly connected to the rotating head 5. The base plate 3 is provided with a limit groove, and the positioning bolt 7 is connected to the limit groove. When the pressing block 12 is pressed against the connecting groove 17, the end of the positioning bolt 7 is aligned with the limit groove. Then, the positioning bolt 7 is rotated so that its end is connected to the limit groove, thereby locking and fixing the rotating head 5.

[0023] Multiple connecting grooves 17 are provided on the inner side of the cover plate body 1, and the end of the pressing block 12 is connected to the connecting groove 17. Usually, two connecting grooves 17 are provided on a single side inside the cover plate body 1, so that the sealing surface 1 9, sealing surface 2 10, and sealing surface 3 11 are evenly pressed against the base plate 3, which effectively improves the sealing performance of the connection between the cover plate body 1 and the base plate 3 and achieves a multi-seal effect.

[0024] Sealing surface 1 (9), sealing surface 2 (10), and sealing surface 3 (11) are made of rubber material, and the cross-section of sealing surface 2 (10) is inclined.

[0025] The height of the connecting groove 17 is high enough to allow the pressing block 12 to be unscrewed from the connecting groove 17, making it easier to loosen and disassemble the cover plate body 1 later.

[0026] A wire harness hole 4 is provided at the center of the base plate 3.

[0027] Working principle: During the installation of the cover plate body 1, the bottom of the cover plate body 1 is aligned with the base plate 3. A tool is used to drive the rotating head 5 to rotate, which in turn drives the worm gear 16 to rotate. The worm gear 16 drives the turbine 15 to rotate, thus rotating the rotating shaft 8. The conical teeth 14 at the end of the rotating shaft 8 drive another conical tooth 14 to rotate, thereby rotating another rotating shaft 8. This causes the four pressing blocks 12 to rotate synchronously, with the ends of the pressing blocks 12 pressing against the connecting groove 17. The same operation is then performed on the rotating head 5 to improve the stability of the cover plate body 1 installation. The three sealing surfaces 9, 10, and 11 effectively improve the sealing between the cover plate body 1 and the base plate 3, achieving a multi-layered sealing effect and preventing the intrusion of dust and water stains. Finally, the corresponding positioning bolts 7 are tightened to limit and fix the rotating head 5, improving the stability of the pressing blocks 12.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
