Further, the closed position of the cover 30 is at the opening portion 101, and when the cover 30 is at the closed position, as shown in fig. 12, the cover 30 covers the opening portion 101, thereby closing the opening portion 101; when the fully open position of the lid 30 is within the automobile body 10 and is away from the opening 101, the lid 30 is within the automobile body 10 and the opening 101 communicates with the inside and outside of the automobile body 10 as shown in fig. 15 when the lid 30 is in the fully open position, thereby opening the opening 101. In particular, the opening/closing cover assembly according to the present invention is an assembly structure, and can be integrally attached to the automobile body 10 or integrally detached from the automobile body 10 by detachably attaching the fixing rail 90 to the automobile body 10.

As shown in fig. 1 to 3, the automotive radar assembly according to the present application includes, in addition to the above-mentioned opening and closing cover assembly, a radar main body 120, a fixed housing 20 fixed in the automotive body 10, and an extending mechanism installed on the fixed housing 20, where the fixed housing 20 is provided with a through hole portion 21 at the opening 101, the through hole portion being opposite to the inside and the outside of the opening 101, the radar main body 120 is movably installed in the fixed housing 20, the radar main body 120 has a retracted position far away from the opening 101 and an extended position at the opening 101, and the extending mechanism acts on the radar main body 120 to drive the radar main body 120 to reciprocate between the retracted position and the extended position, that is, to drive the radar main body 120 to move toward or away from the opening 101; the stationary rail 90 may be directly fixed in the stationary housing 20. In particular, the automotive radar assembly is an assembly structure, and the fixed shell 20 is inserted into the automotive body 10, so that the automotive radar assembly is integrally assembled and disassembled on the automotive body 10.

When the vehicle does not use the automatic driving function or the driving-assist function, as shown in fig. 12, the radar main body 120 is housed in the fixed case 20, that is, the vehicle body 10, in the retracted position, so that the radar main body 120 is built in and concealable; the cover 30 covers the radar main body 120 hidden in the automobile body 10 in the closed position, and blocks and closes the through hole portion 21 and the opening portion 101, thereby providing a uniform appearance to the outer surface of the automobile body 10 for aesthetic reasons, keeping the energy consumption of the vehicle during traveling low for aerodynamic reasons, and protecting the radar main body 120 from environmental influences, unauthorized access, or a certain unintended pressure contact force, etc. for safety reasons, thereby protecting the radar main body 120 in all directions. When the vehicle uses the automatic driving function or the auxiliary driving function, as shown in fig. 15, the driving source is operated to drive the cover plate 30 to move to the full-open position, the cover plate 30 is far away from the through hole part 21 and is wholly contained in the fixed shell 20, the cover plate 30 is hidden towards the inside of the automobile body 10, the through hole part 21 and the opening part 101 are exposed, the inner cavity of the fixed shell 20 is communicated with the opening part 101 through the through hole part 21, and therefore the through hole part 21 of the opening-closing cover assembly and the opening part 101 on the automobile body 10 are opened; then, the extending mechanism operates to drive the radar main body 120 to move outward to the extending position, and as shown in fig. 21, the radar main body 120 is opened to scan the surrounding environment at the opening 101, collect the environmental data, and feed back the environmental data to the on-board chip. After the radar main body 120 is used, the extending mechanism reversely acts to drive the radar main body 120 to reset, and then the driving source reversely acts to drive the cover plate 30 to reset through the driving piece 70 and the transmission slide block 80.

Therefore, in the opening and closing cover assembly and the automobile radar assembly related to the application, the driving source drives the cover plate 30 to reciprocate between the closing position and the full opening position through the driving piece 70 and the transmission sliding block 80, the opening part 101 on the automobile body 10 is automatically opened and closed, the cover plate 30 is removed from manual operation, and the operation experience is improved. Moreover, the cover 30 moves into the automobile body 10 in the opening process, and the cover 30 is integrally stored in the automobile body 10 when in the fully-opened position, so that the integral aesthetic property of the automobile in the opened state of the opening part 101 can be improved; the cover 30 is closed at the through hole 21 and the opening 101 in the closed position and exposed from the opening 101, so that the automobile body 10 has a uniform appearance, and the overall appearance of the automobile in the closed state of the opening 101 is improved.

Further, the installation positions of the opening and closing cover assembly and the automobile radar assembly on the automobile body 10 are determined according to actual requirements; the cover 30 may be moved from the closed position to the fully open position in a variety of ways, such as: the cover plate 30 may move inward upward, inward downward, inward leftward, or inward rightward. For convenience of description, a specific preferred structure of the opening and closing cover assembly and the automotive radar assembly will be described by taking as an example that the opening and closing cover assembly and the automotive radar assembly are mounted on a rear body of an automobile and the cover plate 30 moves from the closed position to the fully opened position in a manner of moving inward and upward; based on this, the full-open position of the cover plate 30 is located on the inner upper side of the closed position, the full-open position and the closed position of the cover plate 30 are distributed relatively up and down, and the opening mode that the cover plate 30 slides inwards and upwards can also save the space depth in the automobile body 10 and reduce the requirement on the internal depth.

As shown in fig. 4 and 5, the cover plate 30 includes a cover carrier 31 and a vehicle-body-like outer cover 32 fixed to an outer end side of the cover carrier 31, and the transmission slider 80 is connected to the cover carrier 31; when the cover 30 is in the closed position, the cover carrier 31 covers the through-hole portion 21, and the vehicle body-like outer cover 32 is located in the opening portion 101. The vehicle-like outer body cover 32 has a finish that is the same as or very close to the vehicle body 10 and a curved surface that is the same as or very close to the vehicle body 10 surrounding it, so that when the cover 30 is in the closed position, the cover 30 can form a substantially seamless transition with the outer surface of the vehicle body 10 via its vehicle-like outer body cover 32, thereby greatly enhancing the uniformity and integrity of the appearance of the vehicle body 10 at that time.

Further, as shown in fig. 9, the first sliding slot 911 and the second sliding slot 922 are opened in the outer rail 92, and the second sliding slot 922 is distributed outside the first sliding slot 921 and is separated from the first sliding slot 921; as shown in fig. 7 and 8, a third sliding chute 911 and a fourth sliding chute 912 are opened in the inner rail 91, and the third sliding chute 911 is distributed outside the fourth sliding chute 912; as shown in fig. 10 and 11, a transmission sliding slot 81 is formed in the transmission sliding block 80, a guide post 82 protruding toward the outer guide rail 92 is disposed on the outer end surface of the transmission sliding block 80, and two guide posts 82 are distributed up and down; as shown in fig. 3 and 6, the cover carrier 31 is provided with an active lead 34 and a passive lead 35 on both left and right sides thereof, which protrude toward the inner rail 91, and the active lead 34 is located on the upper side of the passive lead 35. During assembly, the guide post 82 of the transmission slide block 80 is positioned in the second sliding groove 922 of the outer guide rail 92 and is in sliding fit with the outer guide rail; the driving pin 34 of the cover plate 30 is located in the third sliding groove 911 of the inner guide rail 91, and the driving pin 34 of the cover plate 30 is located in the transmission sliding groove 81 of the transmission sliding block 80, and is in sliding fit and rotating fit; the passive leg 35 of the cover 30 is located in the fourth sliding groove 912 of the inner rail 91, and the two are slidably and rotatably engaged. In particular, as shown in fig. 10 and 11, the transmission chute 81 includes a first groove section 811, and a second groove section 812 connected to a lower end of the first groove section 811, and the first groove section 811 and the second groove section 812 form an obtuse included angle therebetween; as shown in fig. 7 and 8, the third sliding chute 911 includes a third chute section 913 and a fourth chute section 914 connected to the inner end of the third chute section 913, the third chute section 913 extends straight back and forth along the inner and outer directions, and an obtuse included angle is formed between the third chute section 913 and the fourth chute section 914. Based on this structure, the movement of the cover 30 is as follows.

When the cover plate 30 is in the closed position, as shown in fig. 12 to 14, the active pins 34 are in the upper end of the first groove section 811 and the outer end of the third groove section 913, and the passive pins 35 are at the lower end of the fourth chute 912, and may also abut against the lower groove wall of the fourth chute 912. When the transmission slider 80 moves up and down along the second sliding slot 922 and the driving pin 34 moves in the transmission sliding slot 81, as shown in fig. 15 to 17, the driving pin 34 moves and rotates in the third slot segment 913, and the driven pin 35 abuts against and rotates in the fourth sliding slot 912, so that the cover plate 30 rotates inward or outward with the driven pin 35 as a fulcrum. When the cover 30 is in the fully open position, as shown in fig. 18-20, the active pins 34 are in the end of the second slot segment 812 and the upper end of the fourth slot segment 914, and the passive pins 35 are in the upper end of the fourth chute 912.

Thus, the process of moving the cover 30 from the closed position to the fully open position with the motor rotating in the forward direction is as follows: the guide part 70 moves upwards in the first slide slot 921 of the outer guide rail 92, the guide part 70 drives the transmission slide block 80 to move upwards, and the transmission slide block 80 moves upwards along the second slide slot 922 of the outer guide rail 92; firstly, the driving pin 34 slides relatively along the transmission chute 81 from the upper end of the first chute section 811 in the transmission chute 81, and the extension direction of the transmission chute 81 makes the cover plate 30 rotate inward with the driven pin 35 as a fulcrum, so that the driving pin 34 moves inward in the third chute section 913 of the third chute 911 at the same time; after the driving pin 34 abuts against the lower end of the second slot section 812 in the transmission chute 81, as shown in fig. 16 and 17, the driving pin 34 is also at the inner end of the third slot section 913 in the third chute 911, i.e. at the lower end of the fourth slot section 914; thereafter, as the transmission slider 80 moves upward continuously, the transmission slider 80 drives the cover plate 30 to move upward together through the abutting fit of the active pin 34 and the second groove section 812, and the cover plate 30 moves upward to the fully open position in an inward rotation manner. That is, the cover plate 30 is first rotated inward and then moved inward and upward.

The motor reverses and drives the cover 30 from the fully open position to the closed position as follows: the guide piece 70 moves downwards in the first sliding slot 921 of the outer guide rail 92, the guide piece 70 drives the transmission slide block 80 to move downwards, and the transmission slide block 80 moves downwards along the second sliding slot 922 of the outer guide rail 92; firstly, the driving slider 80 drives the cover plate 30 to move downwards together through the abutting fit of the driving pin 34 and the second groove section 812; after the driving pin 34 moves down to the lower end of the fourth slot section 914, along with the continuous downward movement of the transmission slider 80, the driving pin 34 relatively slides along the transmission chute 81 from the inner end of the second slot section 812 in the transmission chute 81, and the driving pin 34 simultaneously moves outward in the third slot section 913 of the third chute 911, so that the cover 30 integrally rotates outward with the driven pin 35 as a fulcrum until the limiting portion 83 at the lower end of the transmission slider 80 abuts against the limiting bump 915 on the inner rail 91, at this time, the vehicle-body-like outer cover 32 of the cover 30 rotates outward into the opening 101 to cover the through hole portion 21 and the opening 101, and the cover 30 is located at the closed position. That is, the cover plate 30 is first moved outward and downward and then rotated outward.

Further, in other embodiments, the cover plate 30 may be single-sided driven; such as: when the left side of the cover 30 is a driving side and the right side is a driven side, the fixed rail 90 on the driving side includes the inner rail 91 and the outer rail 92, but the fixed rail 90 on the driven side may include only the inner rail 91 and not the outer rail 92, and the guide 70 and the transmission slider 80 on the driven side are not required.
