The crank 141 and the roller provided thereon are also made of composite materials. The first link 10 is connected to the third link 12 and the fourth link 13 respectively, and the third link 12 and the fourth link 13 are connected to the left side of the installation box 1. When the vehicle-mounted laser radar 2 is closed, the third link 12 and the fourth link 13 are in a tilted state, and the linked first link 10 is pulled backward by the front slider 19, and at the same time, the third link 12 and the fourth link 13 rotate and pull the first link 10 outward; when the vehicle-mounted laser radar 2 is raised, the movement direction is opposite, and the third link 12 and the fourth link 13 are in a longitudinal state (perpendicular to the first link 10 and the installation box 1), then the linked first link 10 is pulled forward by the front slider 19, and at the same time, the third link 12 and the fourth link 13 rotate and push the first link 10 inward.

[0042] like Figure 5As shown in the specific embodiment, the second connecting member 120 includes a fifth connecting rod 16, a sixth connecting rod 17 and a second connecting rod 15; one end of the fifth connecting rod 16 and the sixth connecting rod 17 is connected to the right side of the installation box 1, specifically connected to the fixed column set in the installation box 1, and the other end of the fifth connecting rod 16 and the sixth connecting rod 17 is connected to the second connecting rod 15, specifically connected to the rotating shaft set on the surface of the second connecting rod 15; the second connecting rod 15 is set on the right side of the installation box through the connected fifth connecting rod 16 and the sixth connecting rod 17, and a second sealing member 18 is set inside the second connecting rod 15; when the vehicle-mounted laser radar 2 is closed, the end of the fifth connecting rod 16 and the sixth connecting rod 17 connected to the second connecting rod 15 is tilted toward the rear slider 21. The second connecting rod 15 is respectively provided with a crank 141 extending inward at both ends, and a roller is provided at the front end of the crank 141 for respectively engaging with the longitudinal roller slideways set on the surfaces of the front slider 19 and the rear slider 21.

[0043] like Figure 6 and Figure 7As shown, in a specific embodiment, a plurality of longitudinal rollers are respectively provided on both sides of the front slider 19 for sliding back and forth in the corresponding transverse roller slide 101; a longitudinal roller slide is provided on the surface of the front slider 19 for allowing the first connecting rod 10 and the second connecting rod 15 to slide left and right through the driving member 14 (roller) provided thereon. The front slider 19 adopts a composite material injection molding structure with four rollers and a roller track. It can move in the installation box 1 through the rollers, and the roller track allows the first connecting rod 10 and the second connecting rod 15 to move left and right through the rollers; the front slider 19 is arranged at the front end of the installation box 1, and the front slider 19 can move back and forth in the installation box 1. The left and right ends of the front slider 19 are respectively connected to the first connecting rod 10 and the second connecting rod 15 through rollers, and a third seal 20 is provided on the inside of the front slider 19; it can be understood that the front slider 19 has four rotatable wheels and can move back and forth in the roller track of the installation box 1; the left and right sides are connected to the first connecting rod 10 and the second connecting rod 15 respectively through two cranks 141 and rollers, and the rollers realize left and right movement in the roller track of the front slider 19.

[0044] like Figure 8 and Figure 9 As shown, the rear slider 21 is provided with multiple longitudinal rollers on both sides, which are used to slide back and forth within the corresponding transverse roller slides 101. The rear slider 21 is provided with longitudinal roller slides on its surface, which allow the first connecting rod 10 and the second connecting rod 15 to slide left and right via the driving members 14 (rollers) provided thereon. The rear slider 21 is a composite injection-molded structure with four rollers and a roller track. The rollers allow it to move within the mounting box 1, and the roller track allows the first connecting rod 10 and the second connecting rod 15 to move left and right via the rollers. A rear slider 21 is provided at the rear end of the installation box 1, and the rear slider 21 can move forward and backward in the installation box 1. The left and right ends of the rear slider 21 are respectively connected to the first connecting rod 10 and the second connecting rod 15 through rollers, and a fourth seal 22 is provided on the inner side of the rear slider 21; it can be understood that the rear slider 21 has four rotatable wheels and can move forward and backward in the roller track of the installation box 1; the left and right sides are respectively glued to the first connecting rod 10 and the second connecting rod 15 through two cranks 141 and rollers, and the rollers realize left and right movement in the roller track of the rear slider 21.

[0045] In this embodiment, the driving member 14 includes a crank 141 and a roller; the crank 141 is respectively arranged at the two ends of the first linking member 110 and the second linking member 120 and extends inward, and the roller is set at the front end of the crank 141, which is used to be embedded in the longitudinal roller slideway set on the surface of the front slider 19 and the rear slider 21.

[0046] like Figures 10 to 12 FIG2 is a schematic diagram of an embodiment of a vehicle roof radar concealment device and sealing system provided by the present application. In this embodiment, the vehicle roof radar concealment device is used to achieve the raising and lowering of the vehicle roof radar sealing system, including:

[0047] A lifting device provided in the installation box, for realizing the lifting and lowering action of the vehicle-mounted laser radar;

[0048] A worm gear 6 is provided on the lifting device, which is used to drive the lifting device to rotate and realize the lifting action; a drive motor 8 is fixed in the installation box 1 and a worm 7 is provided on the drive motor 8, and the worm 7 is connected to the worm gear 6. The drive motor 8 drives the worm 7 and the worm gear 6 in turn to further drive the lifting device to realize the lifting action of the vehicle-mounted laser radar 2;

[0049] Among them, when the driving motor 8 drives the vehicle-mounted laser radar 2 to close, the vehicle-mounted laser radar 2 compresses the sealing ring 9 to seal the gap between the vehicle-mounted laser radar 2 and the installation box 1; when the driving motor 8 drives the lifting device to rise, the worm gear 6 drives the front slider 19 and the rear slider 21 to move forward, and drives the first connecting rod 10 and the second connecting rod 15 to move toward the inside of the installation box 1, compressing the first seal 11, the second seal 18, the third seal 20 and the fourth seal 22 to seal the vehicle-mounted laser radar 2. It can be understood that the radar lifting function is realized by adopting a simple and reliable worm gear 6 and worm 7 in conjunction with a four-bar mechanism (two vertical rods of the seventh link 3, the eighth link 4, and the ninth link 5). The worm gear 6 and worm 7 serve as a transmission mechanism, and the high transmission ratio of the worm gear 6 and worm 7 is used to reduce the torque requirement of the motor, thereby reducing the size and weight of the entire system; the four-bar mechanism is used to achieve the radar position change requirement, with high reliability and stability, and at the same time can resist the load influence caused by external air force when the vehicle is traveling at high speed.

[0050] In a specific embodiment, the lifting device includes a seventh connecting rod 3, an eighth connecting rod 4, and a ninth connecting rod 5; the eighth connecting rod 4 and the ninth connecting rod 5 are correspondingly arranged on both sides of the radar box 2; the top end of the eighth connecting rod 4 is rotatably connected to the outer wall of the radar box 2, and the bottom end of the eighth connecting rod 4 is rotatably connected to the inner wall of the installation box 1; the top end of the ninth connecting rod 5 is rotatably connected to the outer wall of the radar box 2, and the bottom end of the ninth connecting rod 5 is rotatably connected to the inner wall of the installation box 1. The top end of the seventh connecting rod 3 is rotatably connected to the other side of the bottom of the vehicle-mounted laser radar 2, and the bottom end of the seventh connecting rod 3 is connected to the worm gear 6. The seventh connecting rod 3 rotates under the drive of the worm gear 6 to realize the lifting and lowering action of the vehicle-mounted laser radar 2. The seventh connecting rod 3 includes a horizontal rod and a vertical rod; a plurality of vertical rods are respectively arranged on both sides of the vehicle-mounted laser radar 2, and the top ends of the plurality of vertical rods are respectively rotatably connected to the outer wall of the vehicle-mounted laser radar 2, and the two ends of the horizontal rod are respectively connected to the bottom ends of the plurality of vertical rods, and the middle part of the horizontal rod is connected to the worm gear 6. When the vehicle-mounted laser radar 2 is lifted or lowered, the horizontal rod and the vertical rod are driven by the worm gear 6 to rotate and drive the vehicle-mounted laser radar 2 to lift or lower. It can be understood that the seventh connecting rod 3, the eighth connecting rod 4, and the ninth connecting rod 5 are made of steel and are only used to realize the lifting and lowering action of the vehicle-mounted laser radar 2; the worm gear 6 and the worm 7 are made of composite materials to realize the transmission function; the installation box 1 is made of composite materials and is mainly used as a mounting carrier for parts such as the four-link and the motor.

[0051] In this embodiment, Figure 3 As shown, a sealed mounting shell is provided on the top of the mounting box 1. Transverse roller tracks 101 are provided within the sealed mounting shell, corresponding to the front slider 19 and the rear slider 21, respectively, for guiding the front slider 19 and the rear slider 21 forward and backward. Fixed posts corresponding to the first linking member 110 and the second linking member 120 are also provided within the mounting box 1, for connecting the first linking member 110 and the second linking member 120. The mounting box 1 adopts a composite injection molding structure with two roller tracks (transverse roller tracks 101) and four connection points (fixing posts).

[0052] In this embodiment of the present invention, when the lifting mechanism is raised, it drives the front slider 19 and the rear slider 21 forward, and, via the rollers, drives the first connecting rod 10 and the second connecting rod 15 toward the inside of the mounting box 1. This compresses the first seal 11, the second seal 18, the third seal 20, and the fourth seal 22, sealing the vehicle-mounted laser radar. It is understood that the operating principle of this system is that the drive motor 8 drives the worm 7, which in turn rotates the worm gear 6. The worm gear 6 then drives the eighth connecting rod 4 and the ninth connecting rod 5 to rotate about their connection points, thereby driving the vehicle-mounted laser radar 2. When the lifting mechanism is opened, it pushes the front slider 19 forward, rolling it forward. The front left and right cranks 141 and rollers drive the first connecting rod 10 and the second connecting rod 15 toward the center. Simultaneously, the rear two cranks 141 and rollers drive the rear slider 21 forward. Ultimately, when the vehicle-mounted laser radar 2 is in the open position, the extrusion seals surrounding the vehicle-mounted laser radar 2 are compressed, ensuring a tight seal during the opening process. When the lifting device is closed, the rear slider 21 will be pushed backward to roll backward, and the above process will be reversed. The first connecting rod 10 and the second connecting rod 15 will be loosened to both sides, and the front slider 19 will roll backward. When in the closed position, the sealing ring 9 will contact and compress with the outer surface of the top cover to achieve sealing.

[0053] In summary, the implementation of the embodiments of the present invention has the following beneficial effects:

[0054] The vehicle-mounted radar concealment device, sealing system, and vehicle provided by this invention utilize a worm gear as the transmission mechanism, leveraging the worm gear's high transmission ratio to reduce the motor's torque requirements, thereby reducing the overall system size and weight. A four-bar linkage achieves radar position adjustment, offering high reliability and stability while also resisting the effects of aerodynamic loads during high-speed driving. Furthermore, a dual-layer seal is designed to ensure sealing of the radar in both the open and closed positions, ensuring the overall system is waterproof and dustproof.

[0055] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
