DETAILED DESCRIPTION

[0052] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0053] With the rapid development of intelligent driving technology, more and more models are equipped with LiDAR. LiDAR is a radar system that emits light beams to detect the position, speed and other characteristic quantities of a target. It has powerful information perception and processing capabilities, can provide vehicles with accurate environmental perception and distance measurement, and provide key data for path planning, obstacle avoidance and other functions.

[0054] In the related art, the laser radar is usually set on the roof of the vehicle, which has the characteristics of detecting large horizontal elevation angles, long distances, and good vision. However, the roof of the vehicle in the related art is easy to get wet, which can easily damage the laser radar and other components in the vehicle.

[0055] Based on this, an embodiment of the present invention provides a laser radar decorative cover assembly, a laser radar installation device and a vehicle, wherein a first seal arranged along the circumference of the cover plate is provided between the cover plate and the roof sheet metal, and a drainage structure is provided on the first seal, and at least part of the drainage structure is located on the lower side of the first seal in the height direction of the vehicle body. In this way, if water accidentally enters between the cover plate and the roof sheet metal, the water will be discharged to the outside through the drainage gap, and the water will not accumulate between the cover plate and the roof sheet metal, thereby effectively protecting components such as the laser radar, avoiding the laser radar from being damaged due to water entering the roof, and extending the service life of the laser radar to a certain extent.

[0056] The following is a detailed description of the laser radar decorative cover assembly, the laser radar installation device and the vehicle provided by the embodiments of the present invention through specific embodiments in conjunction with the accompanying drawings:

[0057] Reference Figures 1 to 10 As shown, this embodiment provides a laser radar decorative cover assembly 10, which is used to seal and install the laser radar 30 on the roof sheet metal 20, such as the front cross beam of the roof.

[0058] Specifically, refer to Figure 2 and Figure 4 As shown, the laser radar decorative cover assembly 10 provided in this embodiment includes a cover plate 2 for connecting to the roof sheet metal 20, the cover plate 2 is used to install the laser radar 30, and a window 21 is opened on the cover plate 2 for at least exposing the optical window 301 of the laser radar 30, and the cover plate 2 is sealed with the laser radar 30 at least at the window 21.

[0059] When the cover plate 2 and the laser radar 30 are installed in place, the window 21 of the cover plate 2 corresponds to the optical window 301 of the laser radar 30, and the junction of the window 21 and the optical window 301 is sealed to form a seal (positioned as the first seal), with good waterproof sealing. The light beam of the laser radar 30 passes through the window 21 to perceive and judge the obstacles around the vehicle body and the driving environment.

[0060] refer to Figure 1 , Figure 2 and Figure 4 As shown, a first seal 1 is sealed between the cover plate 2 and the roof sheet metal 20. The first seal 1 is arranged at least around the periphery of the window 21 along the circumference of the cover plate 2, and a drainage structure is arranged on the first seal 1, and at least part of the drainage structure is located at least on the lower side of the first seal 1 along the height direction of the vehicle body.

[0061] By making the first seal 1 at least surround the outer periphery of the window 21 along the circumference of the cover plate 2, in other words, the position of the window 21 on the cover plate 2 is located in the area enclosed by the first seal 1, and the first seal 1 is also sealed between the cover plate 2 and the roof sheet metal 20, the laser radar 30 is located in the sealed space defined by the cover plate 2, the roof sheet metal 20 and the first seal 1, so that the first seal 1 forms another seal (positioned as the second seal) for the laser radar 30, and the two seals cooperate with each other to isolate the laser radar 30 from the outside, thereby realizing sealed protection for the laser radar 30.

[0062] In specific implementation, a drainage structure is provided on the first sealing member 1, and the drainage structure is located on the lower side of the first sealing member 1 in the height direction of the vehicle body. In this way, if water accidentally enters the sealed space between the cover plate 2 and the roof sheet metal 20, for example, water accidentally enters the sealed space from the window after the vehicle has been used for a long time, the water will flow to the lower side of the first sealing member 1 and flow out to the outside through the drainage structure. In other words, even if water accidentally enters the sealed space, it will be discharged through the drainage structure, thereby avoiding the accumulation of water in the sealed space and damaging the laser radar 30 or other components in the vehicle, such as the cab. This makes the laser radar decorative cover assembly 10 of this embodiment have better sealing performance and extends the service life of the laser radar 30 to a certain extent.

[0063] By arranging the drainage structure on the side of the first sealing member 1 which is at a lower position along the vehicle body height direction, the drainage structure is at a lower position and is a one-way drainage channel. If water accidentally enters between the cover plate 2 and the roof sheet metal 20, the water can be discharged to the outside through the drainage structure, but the external water will not enter between the cover plate 2 and the roof sheet metal 20 through the drainage structure, so that the first sealing member 1 has a one-way hydrophobic drainage performance on the basis of ensuring the waterproof sealing performance, thereby improving the sealing protection performance.

[0064] In specific implementation, since different areas of the roof sheet metal 20 are usually located at different positions along the height direction of the vehicle body, that is, the position of some areas of the roof sheet metal 20 in the height direction of the vehicle body is higher than the position of other areas of the roof sheet metal 20 in the height direction of the vehicle body, after the cover plate 2 and the roof sheet metal 20 are connected, the positions of different areas of the cover plate 2 and different areas of the first seal 1 along the height direction of the vehicle body are also different.

[0065] The area of ​​the roof sheet metal 20 that is higher in the vehicle body height direction, the corresponding area of ​​the cover plate 2 and the first seal 1 is also higher in the vehicle body height direction. The area of ​​the roof sheet metal 20 that is lower in the vehicle body height direction, the corresponding area of ​​the cover plate 2 and the first seal 1 is also lower in the vehicle body height direction.

[0066] In some implementations, the roof sheet metal 20 may be, for example, a front cross beam of the roof. In the height direction along the vehicle body, for example, the position of the front cross beam of the roof facing the front of the vehicle is lower, and the position of the front cross beam of the roof facing the rear of the vehicle is higher. After the cover plate 2 is connected to the front cross beam of the roof, the positions of the first seal 1 and the cover plate 2 facing the front of the vehicle are both lower, and the positions of the first seal 1 and the cover plate 2 facing the rear of the vehicle are both higher. In a specific implementation, the drainage structure is set on the side of the first seal 1 facing the front of the vehicle.

[0067] Since the first seal 1 is arranged along the circumference of the cover plate 2, in a specific implementation, the drainage structure can be set, for example, in the area of ​​the first seal 1 close to the front windshield of the vehicle. Of course, the drainage structure can also be set on the front side of the side area of ​​the first seal 1 extending along the length direction of the vehicle body.

[0068] The laser radar decorative cover assembly 10 provided in this embodiment is provided with a seal between the window 21 of the cover plate 2 and the optical window 301 of the laser radar 30 by making the cover plate 2 seal with the laser radar 30 at least at the window 21, thereby forming a first seal. A first seal 1 is also provided between the cover plate 2 and the roof sheet metal 20, so that the first seal 1 is at least arranged around the outer periphery of the window 21 along the circumference of the cover plate 2, thereby forming a second seal. In this way, the laser radar 30 is located in the area enclosed by the cover plate 2, the first seal 1 and the roof sheet metal 20, thereby improving the sealing performance, making it difficult for water to enter the area between the cover plate 2 and the roof sheet metal 20, improving the sealing protection performance of the laser radar decorative cover assembly 10, and having a good protective effect on the laser radar 30 and other components in the vehicle.

[0069] At the same time, a drainage structure is provided on the first sealing member 1, and at least part of the drainage structure is located on the side of the first sealing member 1 that is at a lower position along the vehicle body height direction. If water ingress occurs accidentally, for example, after the vehicle has been used for a long time, water accidentally enters between the cover plate 2 and the roof sheet metal 20 from the window 21, due to the existence of the drainage structure, and the drainage structure is located on the side of the first sealing member 1 that is at a lower position along the vehicle body height direction, that is, the drainage structure is located at a lower position, the water will be discharged from the drainage structure to the outside, and the water will not gather between the cover plate 2 and the roof sheet metal 20, thereby effectively protecting components such as the laser radar 30, avoiding the phenomenon of the laser radar 30 being damaged by water ingress on the roof, and extending the service life of the laser radar 30 to a certain extent.

[0070] refer to Figure 2 and Figure 4 As shown, in some embodiments, the drainage structure includes a drainage notch 4 provided on the first sealing member 1, which has a simple structure and is easy to implement.

[0071] In a specific implementation, the first sealing member 1 includes at least one sub-segment, which is arranged along the circumference of the cover plate 2, and the two ends of the sub-segment are spaced apart on the lower side of the cover plate 2, and the spacing area between the two ends forms a drainage gap 4.

[0072] When the cover plate 2 is connected to the roof sheet metal 20, the first seal 1 achieves sealing, but the first seal 1 does not contact the roof sheet metal 20 at the drainage notch 4, and the drainage notch 4 and the roof sheet metal 20 define a drainage hole for water to flow out. Since the drainage notch 4 is located on the lower side of the first seal 1, the drainage hole is located at a lower position on the roof, so external water will not enter the sealed space between the cover plate 2 and the roof sheet metal 20 from the drainage hole, that is, the drainage notch 4 and the drainage hole have a one-way flow function, which achieves a good protection effect on the laser radar 30.

[0073] In other embodiments, the drainage structure is, for example, a drainage pipe embedded in the first sealing member 1, one end of the drainage pipe is connected to the sealed space, and the other end of the drainage pipe is connected to the outside.

[0074] refer to Figure 2 and Figure 4As shown, in some embodiments, at least two drainage gaps 4 are arranged at intervals on the lower side of the first sealing member 1 along the height direction of the vehicle body, that is, the first sealing member 1 is provided with multiple drainage gaps 4 on its lower side, so that multiple drainage holes are formed at the lower positions of both the cover plate 2 and the roof sheet metal 20. This arrangement increases the number of drainage paths. Once water accidentally enters, it can be discharged through multiple drainage holes, which facilitates the water to be discharged as quickly as possible, thereby improving the sealing between the cover plate 2 and the roof sheet metal 20, thereby improving the protective effect of the laser radar decorative cover assembly 10 of this embodiment on the laser radar 30 and other components in the vehicle.

[0075] refer to Figure 4 As shown, in some embodiments, the projection of at least one drainage gap 4 in the width direction of the vehicle body overlaps with the projection of the window 21 in the width direction of the vehicle body, that is, among the multiple drainage gaps 4, the position of at least one drainage gap 4 on the cover plate 2 corresponds to the position of the window 21 on the cover plate 2, and along the width direction of the vehicle body, at least part of the drainage gap 4 is located directly in front of the window 21, which shortens the drainage path to a certain extent, for example, water that accidentally enters through the window can be discharged as soon as possible.

[0076] refer to Figure 2 and Figure 4 As shown, in some embodiments, there is at least one drainage gap 4 on both sides of the window 21 along the width direction of the vehicle body, that is, on the lower side of the cover plate 2, drainage gaps 4 are provided on both sides of the window 21. On the basis of increasing the number of drainage paths, the arrangement of the drainage paths is also optimized. Once water accidentally enters the window 21, it can be discharged from both sides of the window 21 respectively. In this way, the entered water can be discharged faster, further improving the sealing performance of the laser radar decorative cover assembly 10 of this embodiment, and better protecting the laser radar 30 and other components in the vehicle.

[0077] For example, reference Figure 2 and Figure 4 As shown, the first sealing member 1 includes three sub-segments, and the three sub-segments are arranged at intervals along the circumference of the cover plate 2. Specifically, two of the sub-segments are located on the lower side of the cover plate 2 and are arranged at intervals, and another sub-segment is arranged on the other side of the cover plate 2 along the circumference of the cover plate 2 and is arranged at intervals from the other two sub-segments, so that a drainage gap 4 is formed between each of the two adjacent sub-segments, and three sealing gaps are formed on the first sealing member 1 enclosed by the three sub-segments, and the three sealing gaps are all located on the lower side of the cover plate 2, and the drainage and hydrophobic performance is good.

[0078] refer to Figures 2 to 6As shown, in some embodiments, the first seal 1 is connected to the side of the cover plate 2 facing the roof sheet metal 20. The cover plate 2 is provided with a positioning groove 5, the shape of which matches the shape of the first seal 1, the first seal 1 is connected in the positioning groove 5, and the side of the first seal 1 facing away from the cover plate 2 is exposed outside the positioning groove 5, so that the first seal 1 abuts against the side of the roof sheet metal 20 facing the cover plate 2.

[0079] By providing the positioning grooves 5 on the side of the cover plate 2 facing the roof sheet metal 20, the positioning grooves 5 are arranged along the circumference of the cover plate 2, and the shape of the positioning grooves 5 matches the shape of the first seal 1, and the first seal 1 is connected in the positioning grooves 5, it is relatively convenient to connect the first seal 1 to the cover plate 2, and the assembly is convenient. At the same time, the positioning grooves 5 have a certain limiting effect on the first seal 1, especially when the first seal 1 is connected and matched with the cover plate 2 and the roof sheet metal 20, the limiting effect on the first seal 1 is better, so that the second seal is relatively firm and stable.

[0080] Furthermore, connecting the first seal 1 in the positioning groove 5 of the cover plate 2 also increases the connection area between the first seal 1 and the cover plate 2, thereby improving the connection strength of the first seal 1 on the cover plate 2 and further improving the stability and sealing performance of the second seal.

[0081] In some implementations, the first sealing member 1 may be adhered in the positioning groove 5 by, for example, structural adhesive.

[0082] refer to Figure 6 As shown, in some embodiments, two ribs 6 are provided on the cover plate 2, each rib 6 is extended along the circumference of the cover plate 2, and the two ribs 6 are spaced apart in the direction from the window 21 to the edge of the cover plate 2, and the positioning groove 5 shown is defined between the two ribs 6, which has a simple structure, is easy to manufacture, and is convenient and firm to connect.

[0083] In some implementations, the convex ribs may be integrally formed with the cover plate, for example, to provide a high structural strength.

[0084] In some embodiments, a water passage is provided at the position of the positioning groove 5 corresponding to the drainage notch 4 , and the water passage is aligned with and connected to the drainage hole to facilitate the water to be discharged as quickly as possible.

[0085] In specific implementation, along the circumference of the cover plate 2, the size of the water passage is not less than the size of the drainage gap 4, that is, the opening size of the water passage is greater than or equal to the size of the drainage gap 4, and the hydrophobicity is better.

[0086] In other embodiments, the first sealing member 1 may also be connected to a surface of the roof sheet metal 20 facing the cover plate 2 , for example.

[0087] refer to Figure 4 as well as Figures 7 to 9 As shown, in some embodiments, the laser radar decorative cover assembly 10 further includes a second seal 3 , and the window 21 and the laser radar 30 are sealed by the second seal 3 , and the sealing effect is better.

[0088] In some implementations, the second sealing member 3 , for example, comprises a waterproof rubber sleeve mounted on the laser radar 30 , which has a simple structure, is easy to manufacture, and has a good sealing effect.

[0089] In some embodiments, reference Figure 7 As shown, the second sealing member 3 is disposed on the circumferential outer wall of the optical window 301 and is fixed relative to the laser radar 30 . The side of the second sealing member 3 facing away from the laser radar 30 is used to abut against the cover plate 2 .

[0090] The second sealing member 3 has a certain elasticity and can undergo elastic deformation. When the cover plate 2 and the laser radar 30 are connected, the second sealing member 3 is compressed and abuts against the cover plate 2. The second sealing member 3 is compressed to achieve sealing between the window 21 on the cover plate 2 and the optical window 301 of the laser radar 30, thereby playing a good sealing and protective role.

[0091] In some implementations, the second seal 3 can be bonded to the laser radar 30, for example, so that the connection is convenient and firm.

[0092] Of course, in other embodiments, the second sealing member 3 may also be connected to the side of the cover plate 2 facing the laser radar 30 , and be arranged around the circumference of the window 21 .

[0093] refer to Figure 8 and Fig. 9 As shown, in some embodiments, a non-slip sealing structure 7 for abutting against the second seal 3 is provided at the position of the cover plate 2 that cooperates with the second seal 3. The non-slip sealing structure 7 is arranged on the side of the cover plate 2 facing the roof sheet metal 20 along the circumference of the window 21. The non-slip sealing structure 7 has a certain limiting effect on the second seal 3, so that the sealing abutment between the second seal 3 and the cover plate 2 is relatively firm, further preventing water from entering from the second seal 3, thereby improving the sealing performance of the first seal, so that the laser radar decorative cover assembly 10 of this embodiment has better protection performance for the laser radar 30 and other components in the vehicle.

[0094] In some implementations, reference Fig. 9 As shown, the anti-slip sealing structure 7 is a serrated structure. In this way, the anti-slip sealing structure 7 not only limits the second sealing member 3, but also increases the sealing bonding area between the second sealing member 3 and the cover plate 2, thereby further improving the sealing performance of the first seal, thereby providing better protection for the laser radar 30 and other components in the vehicle.

[0095] refer to Figure 7 As shown, in some embodiments, a first limiting structure is provided between the second sealing member 3 and the laser radar 30, and the first limiting structure is used to limit the second sealing member 3 when the laser radar 30 and the cover plate 2 are connected, so that the sealing performance of the first seal is better.
