[0002] With the continuous development of the automotive industry in recent years, the demand for intelligent driving is getting higher and higher. Vehicle manufacturers all increase the lidar to improve the intelligent driving level, and at the same time need to add a lidar cover. And the lidar is arranged on the upper side of the cab. In the existing solutions, most of them adopt Figure 1 the shown solution to fix the lidar cover. However, since the circumferential limiting rib ( Figure 1 the component shown as A in Figure 1 the figure) on the cover is used to abut against the roof sheet metal, after the connecting assembly compresses and seals the roof sheet metal and the cover body, the position of the cover corresponding to the connecting assembly is subjected to a downward force, resulting in appearance defects such as pits at the position of the cover corresponding to the connecting assembly ( the position shown as B in

[0003] In view of this, the present application provides a lidar cover assembly to solve the problem of appearance defects such as pits on the cover. The present application also provides a vehicle including the above lidar cover assembly.

And when the locking member and the connecting member are in a locked state, the annular foam is in a compressed state. The locking member and the protrusion are respectively located on two sides of the roof sheet metal and both abut against the roof sheet metal to realize the connection between the cover and the roof sheet metal.

The cover plate further includes an anti-disengagement part arranged at the open end, and the anti-disengagement part can abut against the side part of the first plate body and / or the side part of the second plate body.

[0013] Optionally, the lidar cover plate assembly further includes a limiting bump protruding from the hole wall of the strip-shaped hole towards the middle of the strip-shaped hole. There are a plurality of the limiting bumps, and the plurality of limiting bumps are respectively arranged on the hole walls corresponding to both sides in the width direction of the strip-shaped hole to limit the connecting column.

[0039] This application provides a lidar cover assembly. This application also provides a vehicle including the above lidar cover assembly.

[0040] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0041] As Figure 1 shown, in the background art, most of the existing solutions adopt the Figure 1 shown solution to fix the lidar cover. However, since the circumferential limiting ribs located on the cover plate ( Figure 1 the position shown as A in Figure 1 ) are used to abut against the roof sheet metal, after the connecting assembly compresses and seals the roof sheet metal and the cover body, due to the abutment of the limiting ribs of the cover plate against the roof sheet metal, the position of the cover plate corresponding to the connecting assembly is subjected to a downward force due to the existence of the limiting ribs, resulting in appearance defects such as pits at the position of the cover plate corresponding to the connecting assembly (

[0042] the position shown as B in Figures 2 - 7As shown, the embodiment of the present application provides a laser radar cover assembly, which is used in vehicles, especially vehicles with intelligent driving functions. The laser radar cover assembly mainly includes a cover 1 connected to the roof sheet metal 2 of the vehicle, and a connecting assembly 3 for connecting the roof sheet metal 2 and the cover 1 to achieve the installation of the cover 1 on the roof sheet metal 2, and the connecting assembly 3 includes a connecting member 31 and a locking member 32. Among them, the connecting member 31 includes a connecting portion 311 and a limiting portion 312. The connecting portion 311 can pass through the connecting hole 21 opened on the roof sheet metal 2, and a partial area of ​​the connecting portion 311 extends out of the connecting hole 21. The portion of the connecting portion 311 extending out of the connecting hole 21 is used to connect with the locking member 32; the limiting portion 312 is connected to the connecting portion 311, and the cover plate 1 is connected to the limiting portion 312, so that the cover plate 1 is fixed on the roof sheet metal 2 when the connecting portion 311 and the locking member 32 are locked; the locking member 32 is connected to the portion of the connecting portion 311 extending out of the connecting hole 21. Exemplarily, the connection method of the locking member 32 and the connecting portion 311 can be a threaded connection.

[0043] Among them, a protrusion 33 and an annular foam 34 are set on the side of the limiting portion 312 facing the connecting portion 311, and the annular foam 34 is located on the circumferential outer side of the protrusion 33. Specifically, the protrusion 33 and the annular foam 34 are arranged on the side of the first plate body 3122 (to be explained below) away from the second plate body 3123 (to be explained below); and when the locking member 32 and the connecting member 31 are in a locked state, the annular foam 34 is in a compressed state, the locking member 32 and the protrusion 33 are respectively located on both sides of the roof sheet metal 2, and the locking member 32 and the protrusion 33 are both abutted against the roof sheet metal 2 to realize the connection between the cover plate 1 and the roof sheet metal 2. In this way, when the cover plate 1 and the roof sheet metal 2 are connected together through the connection component 3, the connection part 311 is extended into the mounting hole of the roof sheet metal 2, and the cover plate 1 is connected with the limiting part 312, so that when the locking member 32 is locked with the connection part 311 extending out of the mounting hole, the cover plate 1 and the roof sheet metal 2 are gradually approached, and when the locking member 32 and the protrusion 33 are both in contact with the roof sheet metal 2, the locking member 32 and the connection part 311 are in a locked state, so that the cover plate 1 and the roof sheet metal 2 are also in a locked state, so as to realize the connection between the cover plate 1 and the roof sheet metal 2. In this way, the setting of the limiting rib in the cover plate 1 can be omitted, and the connection between the cover plate 1 and the roof sheet metal 2 can be realized only by the setting of the connection component 3, thereby improving the convenience of connecting the cover plate 1 and the roof sheet metal 2.

[0044] It should be noted that the connection method between the cover plate 1 and the limiting portion 312 is not limited herein. Exemplarily, the cover plate 1 can be connected to the limiting portion 312 by at least one of the connection methods such as abutment, clamping, bonding, and threaded connection.

[0045] The lidar component with the above structure realizes the connection between the cover plate 1 and the roof sheet metal 2 by setting a connection component 3 for connecting the roof sheet metal 2 and the cover plate 1. The connection component 3 includes a connecting piece 31 and a locking piece 32. The connecting piece 31 includes a connecting portion 311 passing through the connection hole 21 of the roof sheet metal 2 and a limiting portion 312 connected to the connecting portion 311, and the cover plate 1 is connected to the limiting portion 312. The locking piece 32 is connected to the portion of the connecting portion 311 extending out of the connection hole 21. Moreover, a protrusion 33 and an annular foam 34 are provided on one side of the limiting portion 312 facing the connecting portion 311. The annular foam 34 is located on the circumferential outer side of the protrusion 33. And when the locking piece 32 and the connecting piece 31 are in the locked state, the locking piece 32 and the protrusion 33 are respectively located on both sides of the roof sheet metal 2 and are both in contact with the roof sheet metal 2. With such a setting, the connection between the cover plate 1 and the roof sheet metal 2 can be realized through the setting of the connection component 3. With such a setting, the connection between the roof sheet metal 2 and the cover plate 1 can be realized without setting a limiting rib on the cover plate 1. In this way, when the cover plate 1 and the roof sheet metal 2 are in the connected state, the position of the cover plate 1 corresponding to the connection component 3 will not be subjected to a downward force, thereby avoiding appearance defects such as dents at the position of the cover plate 1 corresponding to the connection component 3. And when the cover plate 1 and the roof sheet metal 2 are in the connected state, the annular foam 34 is in a compressed state. By setting the annular foam 34, a waterproof effect can be achieved to improve the waterproof performance of the lidar cover plate assembly. In addition, the setting of the limiting rib in the cover plate 1 can be omitted, simplifying the structure of the cover plate 1 and reducing the processing difficulty of the cover plate 1.

[0046] In some embodiments, please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 , the limiting portion 312 includes a connecting column 3121, a first plate body 3122 connected to the connecting column 3121 and close to the connecting portion 311, and a second plate body 3123 connected to the connecting column 3121 and far from the connecting portion 311. Among them, the first plate body 3122, the second plate body 3123 and the connecting column 3121 enclose a limiting groove 3124; a strip-shaped hole 11 is opened on the cover plate 1, and the hole wall of the strip-shaped hole 11 is located in the limiting groove 3124. That is to say, the limiting portion 312 realizes the connection with the cover plate 1 in a form of abutment, and the hole walls on both sides of the strip-shaped hole 11 are both in contact with the limiting groove 3124, which can improve the stability of the abutment between the limiting portion 312 and the cover plate 1 and improve the stability of the connection component 3 to realize the connection between the cover plate 1 and the roof sheet metal 2.

[0047] Moreover, the strip-shaped hole 11 moves relative to the connection component 3 when the cover plate 1 deforms. It should be noted that the deformation of the cover plate 1 refers to the deformation caused by the thermal expansion and contraction of the cover plate 1. Although the connection component 3 fixes the cover plate 1 and the roof sheet metal 2 in the Figure 5 Z direction shown, the deformation of the cover plate 1 is in the Figure 5a Y-direction movement as shown, at this time, the cover plate 1 can move relative to the connecting component 3 along the strip-shaped hole 11, that is to say, the connecting component 3 can move relative to the cover plate 1 Figure 7 from the position shown by P in

[0048] to the position shown by M or the position shown by N. Specifically, when the cover plate 1 is displaced due to thermal expansion and contraction, the connecting component 3 does not move while the strip-shaped hole 11 moves, so that relative movement occurs between the strip-shaped hole 11 and the connecting component 3. With such a setting, it is possible to prevent the cover plate 1 from bulging due to thermal expansion and contraction and avoid affecting the appearance of the cover plate 1. Figure 4 and Figure 7 , one end of the strip-shaped hole 11 is a closed end ( Figure 4 the C area shown) and the other end is an open end ( Figure 4 the E area shown). The cover plate 1 further includes an anti-displacement member 12 provided at the open end. When the cover plate 1 is deformed, resulting in relative displacement between the strip-shaped hole 11 and the connecting component 3, the closed end limits the connecting component 3 from one end of the strip-shaped hole 11, and the anti-displacement member 12 limits the connecting component 3 from the other end. In this way, it is possible to prevent the connecting component 3 from moving out of the strip-shaped hole 11, so as to improve the connection stability between the cover plate 1 and the roof sheet metal 2 through the connecting component 3 when the cover plate 1 is deformed, resulting in relative displacement between the strip-shaped hole 11 and the connecting component 3.

[0049] Moreover, the anti-displacement member 12 can be in contact with the side of the first plate body 3122 and / or the side of the second plate body 3123. Since the connecting column 3121 is at the same height as the strip-shaped hole 11, the anti-displacement member 12 is arranged offset from the strip-shaped hole 11. By contacting the side of the first plate body 3122 and / or the side of the second plate body 3123, it is possible to prevent the connecting component 3 from moving out of the strip-shaped hole 11 when the cover plate 1 is deformed, resulting in relative displacement between the strip-shaped hole 11 and the connecting component 3.

[0050] In addition, the anti-displacement member 12 may not be provided, or the strip-shaped hole 11 may be set very long. At this time, both ends of the strip-shaped hole 11 are open ends or one end of the strip-shaped hole 11 is a closed end and the other end is an open end, as long as it is ensured that when the cover plate 1 is deformed due to thermal expansion and contraction and relative movement occurs between the strip-shaped hole 11 and the connecting component 3, the connecting component 3 does not move out of the strip-shaped hole 11.

[0051] In some embodiments, please refer to Figure 4 and Figure 7, the lidar cover assembly further includes a limiting bump 13 protruding from the hole wall of the strip-shaped hole 11 towards the middle of the strip-shaped hole 11. There are multiple limiting bumps 13, and the multiple limiting bumps 13 are respectively arranged on the hole walls corresponding to both sides in the width direction of the strip-shaped hole 11 to limit the limiting post at two positions, thereby improving the limiting effect on the connecting post 3121 and enhancing the stability of the connection between the cover 1 and the roof sheet metal 2 through the connecting assembly 3. Specifically, the arrangement of the limiting bumps 13 can better limit the installation position of the connecting assembly 3 and play a role of pre-limiting, so that the cover 1 and the roof sheet metal 2 can be quickly installed through the connecting assembly 3 to improve the assembly efficiency of the cover 1 and the roof sheet metal 2. Moreover, when the cover 1 deforms due to thermal expansion and contraction, causing relative displacement between the strip-shaped hole 11 and the connecting assembly 3, under the action of the force generated by the deformation of the cover 1, the connecting assembly 3 can also relatively move out of the limiting bumps 13 so that the limiting bumps 13 do not affect the relative displacement between the strip-shaped hole 11 and the connecting assembly 3.

[0052] In some embodiments, please refer to Figure 4 and Figure 7 , during the process of installing the connecting post 3121 into the strip-shaped hole 11, in the length direction of the strip-shaped hole 11, the connecting post 3121 is located between two adjacent limiting bumps 13. That is to say, the installation position of the connecting post 3121 of the connecting assembly 3 is limited by the two limiting bumps 13. During the installation process of the connecting assembly 3, the connecting post 3121 is arranged close to the above two limiting bumps 13 and is located between two adjacent limiting bumps 13, so that the connecting part 311 of the connecting assembly 3 can be smoothly and efficiently inserted into the installation hole of the roof sheet metal 2, thereby improving the installation efficiency of the connecting assembly 3.

[0053] It should be noted that the length direction of the strip-shaped hole 11 refers to Figure 4 the direction indicated by the double-headed arrow Y in

[0054] In some embodiments, please refer to Figure 4 and Figure 7 , during the process of installing the connecting post 3121 into the strip-shaped hole 11, in the width direction of the strip-shaped hole 11, the connecting post 3121 is located between two adjacent limiting bumps 13. That is to say, the installation position of the connecting post 3121 of the connecting assembly 3 is limited by the two limiting bumps 13. During the installation process of the connecting assembly 3, the connecting post 3121 is arranged close to the above two limiting bumps 13 and is located between two adjacent limiting bumps 13, so that the connecting part 311 of the connecting assembly 3 can be smoothly and efficiently inserted into the installation hole of the roof sheet metal 2, thereby improving the installation efficiency of the connecting assembly 3.

[0055] It should be noted that the width direction of the strip-shaped hole 11 refers to Figure 4 the direction indicated by the double-headed arrow X in

[0056] Further, during the process of installing the connecting column 3121 into the strip-shaped hole 11, in the length direction of the strip-shaped hole 11, ensure that the connecting column 3121 is located between two adjacent limiting bumps 13, and in the width direction of the strip-shaped hole 11, ensure that the connecting column 3121 is located between two adjacent limiting bumps 13. With such a setting, the installation position of the connecting column 3121 can be more accurately positioned, and the installation efficiency of the connecting component 3 can be further improved.

[0057] In some embodiments, refer to Figure 4 , in the width direction of the strip-shaped hole 11, the distance between two correspondingly arranged limiting bumps 13 is L, and the diameter of the connecting column 3121 is D, where the relationship between L and D satisfies: 0 < D - L ≤ 0.5 mm. Exemplarily, the limiting bump 13 is PC + ABS, PC + PET-MD15 or PC + ABS-MD15, etc. The limiting bump 13 is usually integrally formed with the cover plate 1. Since the limiting bump 13 is provided on the side wall of the strip-shaped hole 11, the limiting bump 13 can deform so that the connecting column 3121 can escape from the limitation of the limiting bump 13. Ensuring that the distance between two correspondingly arranged limiting bumps 13 and the diameter of the connecting column 3121 satisfy the above relationship can, while achieving the limiting effect, ensure that when the cover plate 1 deforms due to thermal expansion and contraction and the strip-shaped hole 11 and the connecting component 3 undergo relative displacement, the connecting column 3121 can move out of the limiting position of the limiting bump 13 to prevent the cover plate 1 from bulging.

[0058] Exemplarily, the difference between the distance between two correspondingly arranged limiting bumps 13 and the diameter of the connecting column 3121 can be: 0.02 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc.

[0059] In some embodiments, refer to Figure 5 , in the length direction of the connecting portion 311, the height of the annular foam 34 is H, and the height of the protrusion 33 is h, where the relationship between H and h satisfies: 1 < H / h ≤ 4. Ensuring that the height of the annular foam 34 and the height of the protrusion 33 satisfy the above range can, when the locking member 32 and the connecting portion 311 are in a locked state, that is, when the protrusion 33 and the locking member 32 are respectively in contact with both sides of the vehicle roof sheet metal 2, ensure that the foam is in a compressed state; moreover, avoid the height of the foam being too large, so as to avoid the protrusion 33 being unable to contact the vehicle roof sheet metal 2 when the locking member 32 is connected and locked with the connecting portion 311. To ensure the waterproof effect of the annular foam 34 while improving the stability of using the connecting component 3 to connect the cover plate 1 and the vehicle roof sheet metal 2.

[0060] Exemplarily, the ratio of the height of the annular foam 34 to the height of the protrusion 33 can be: 1.1, 1.5, 2, 2.5, 3, 3.5, 4, etc.

[0061] It should be noted that the length direction of the connecting portion 311 is Figure 5 the direction indicated by the double-headed arrow Z in

[0062] In some embodiments, the density ρ of the annular foam 34 satisfies: 60 kg / m 3 ≤ ρ ≤ 180 kg / m 3 . By ensuring that the density of the annular foam 34 satisfies the above range, on the one hand, it avoids the density of the annular foam 34 being too small, so that the annular foam 34 cannot play a waterproof role when the connecting component 3 is in the locked state; on the other hand, it can avoid the density of the annular foam 34 being too large, so that the protrusion 33 cannot abut against the roof sheet metal 2 when the locking member 32 is connected and locked with the connecting portion 311. Such a setting is to improve the stability of connecting the cover plate 1 and the roof sheet metal 2 using the connecting component 3 while ensuring the waterproof effect of the annular foam 34.

[0063] Exemplarily, the density of the annular foam 34 can be: 60 kg / m 3 , 65 kg / m 3 , 70 kg / m 3 , 80 kg / m 3 , 100 kg / m 3 , 110 kg / m 3 , 120 kg / m 3 , 130 kg / m 3 , 150 kg / m 3 , 170 kg / m 3 , 1750 kg / m 3 , 180 kg / m 3 , etc.

[0064] In some embodiments, please refer to Figure 5 , in the radial direction of the connecting portion 311, the width of the annular foam 34 is W, where W satisfies: W ≥ 2 mm. By ensuring that the width of the annular foam 34 satisfies the above range, it avoids the width of the annular foam 34 being too small, so that the annular foam 34 cannot play a waterproof role or the waterproof effect of the annular foam 34 is poor after compression. Such a setting is to improve the waterproof effect of the annular foam 34.

[0065] It should be noted that the radial direction of the connecting portion 311 is Figure 5 the direction indicated by the arrow Y in

[0066] Exemplarily, the width of the annular foam 34 can be 2mm, 2.1mm, 2.5mm, 2.8mm, 3mm, 3.5mm, 4mm, 5mm, 8mm, 10mm, 20mm, etc.
