Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a radar zone waterproof structure and a vehicle equipped with the radar zone waterproof structure. Background Technology

[0002] Automotive water management development focuses on researching and improving the waterproofing performance of vehicles under conditions such as rain, car wash, wading, fog, and other waterproofing challenges. Automotive water management is a key indicator in automotive performance development.

[0003] Many passenger vehicles are now equipped with forward-facing lidar systems. However, due to issues with the fit between the exterior plastic parts and the lidar, there is a risk of water leakage in the lidar area. For example, the forward-facing lidar is mounted on the front roof crossbeam via a bracket. Due to the vehicle's design, the lidar mounting area is a recessed structure covered by a cover plate. If a leak occurs, water cannot drain out, resulting in water remaining in the lidar mounting area for extended periods. Prolonged submersion of these mounting points poses a risk of water seeping into the dry area of ​​the front roof crossbeam and even into the vehicle interior. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a waterproof structure and vehicle for the radar area, which can solve the problem of water leakage in the radar installation area that is limited by shape.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0007] The water guide channel is used to guide the accumulated water in the recessed area into the drain outlet;

[0008] The mounting area is used to connect the radar body; at least part of the mounting area is adjacent to the water guide channel area and protrudes upward relative to the water guide channel area to form the water guide side of the water guide channel area.

[0009] The marking area is used to form a boss indicating the installation direction. At least part of the marking area is adjacent to the water guide channel area and protrudes upward relative to the water guide channel area to form the water guide side of the water guide channel area.

[0010] Optionally, in the above-described radar zone waterproof structure, the drainage outlet is located on the front side of the recessed area.

[0015] Optionally, in the above-mentioned radar zone waterproof structure, the material of the sealing strip includes waterproof foam;

[0016] And / or, the sealing strip protrudes from the inner side of the cover plate and is fixedly connected thereto.

[0017] Optionally, in the above-mentioned radar area waterproof structure, the water guiding channel area includes a first channel segment and a second channel segment located on both sides of the marking area;

[0018] In the depth direction of the drain outlet:

[0019] One end of the first trough section is connected to the drain outlet, and the other end is inclined in a direction away from the central axis of the drain outlet;

[0020] One end of the second trough is connected to the drain outlet, and the other end is inclined in a direction away from the central axis of the drain outlet.

[0021] Optionally, the aforementioned waterproof structure for the radar area also includes water-retaining ribs;

[0022] The water-blocking rib is further away from the recessed area relative to the sealing strip;

[0023] At least a portion of the water-blocking rib is located on the rear side of the recessed area and on both sides of the recessed area.

[0024] Optionally, the above-described waterproof structure for the radar area further includes a bracket for mounting the radar body, the radar body being located between the bracket and the cover plate, the bracket being positioned above the marking area and connected to the mounting area via fasteners, the fasteners including bolts and nuts, wherein:

[0025] The installation area is a double-layer tower structure;

[0026] And / or, the nut is located above the bracket, and the nut is sealed to the bolt with a chemical locking adhesive;

[0027] And / or, the nut is sealed to the bracket by an annular weld;

[0028] And / or, a sealing gasket is provided between the bottom surface of the bracket and the top surface of the mounting area.

Thus, a water-guiding channel area is formed on the bottom surface of the recessed area between the installation area and the marking area. This water-guiding channel area can guide the water entering the recessed area, allowing the water to be discharged through the drain outlet to the outside of the radar installation area (i.e., the recessed area), preventing water from entering the dry area of ​​the crossbeam through the gaps at the radar installation point.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Please see Figure 1 and Figure 2 as well as Figure 5This application provides a waterproof structure for a radar area, which includes a crossbeam 1 and a cover plate 3. The crossbeam 1, sometimes also called the front roof beam or front roof crossbeam, is located at the front end of the vehicle roof and is usually connected to the A-pillars on the left and right sides (i.e., the pillars on both sides of the windshield). The crossbeam 1 is provided with a recessed area for mounting the radar body 4. The bottom surface of the recessed area includes a water guide channel area 110, an installation area 12, and a marking area 11. Wherein: the water guide channel area 110 is used to guide the water accumulated in the recessed area into the drain outlet 10; the mounting area 12 is used to connect the radar body 4, and at least part of the mounting area 12 is adjacent to the water guide channel area 110 and protrudes upward relative to the water guide channel area 110 to form the water guide side of the water guide channel area 110; the marking area 11 is used to form a boss indicating the installation direction (i.e., the installation direction of the crossbeam 1 on the vehicle body and / or the installation direction of the radar body 4), and at least part of the marking area 11 is adjacent to the water guide channel area 110 and protrudes upward relative to the water guide channel area 110 to form the water guide side of the water guide channel area 110. The cover plate 3, sometimes also called a radar dome, is used to cover the above-mentioned recessed area; and on the circumferential outer side of the above-mentioned recessed area, a section between the cover plate 3 and the crossbeam 1 is sealed and connected by a sealing strip 31, and a section is provided with a drain outlet 10 communicating with the water guide channel area 110 of the recessed area.

[0052] As can be seen, the waterproof structure of this radar area not only includes an installation area 12 for connecting the radar body 4 and a marking area 11 for indicating the installation direction, but both the installation area 12 and the marking area 11 are raised structures that form the water-guiding side of the water-guiding channel area 110. Thus, a water-guiding channel area 110 is formed between the installation area 12 and the marking area 11 on the bottom surface of the recessed area. This water-guiding channel area 110 can guide the water entering the recessed area, allowing it to be discharged through the drain outlet 10 to the outside of the radar installation area (i.e., the recessed area), preventing water from entering the dry area of ​​the crossbeam (including the inner cavity of the crossbeam below the upper plate 1') through the gaps at the radar installation point.

[0053] In some embodiments, the drain outlet 110 is constructed by removing a portion of the sealing section between the circumferential side of the recessed area and the cover plate 3 (i.e., the sealing strip 31 is broken to form a gap), eliminating the need for other accessories. This reduces assembly steps, improves production efficiency, and lowers production costs. Therefore, in the radar area waterproof structure provided in this application, the crossbeam 1 and the cover plate 3 cooperate to form a drainage structure in the recessed area used to install the radar body 4. When water accumulates in this area, the water can be automatically guided and discharged through the water guide channel area 110 and the drain outlet 10, preventing immersion of the radar installation point. The flow direction of water entering and exiting the recessed area during this process can be seen in [reference needed]. Figure 2 The arrow in the image indicates the direction of the water flow. It is evident that this application defines the wet zone of the radar installation area (meaning the area where water can enter and exit) at the lowest cost, ensuring that water can be drained promptly and effectively when it enters the recessed area where the radar body 4 is installed, preventing it from entering the dry area of ​​the crossbeam.

[0054] Please see Figure 2 and Figure 3 In some embodiments, the drain outlet 10 is located on the front side of the aforementioned recessed area, and the marking area 11 is an arrow-shaped rib structure with the apex of the arrow facing the drain outlet 10. This rib structure can be formed by stamping and bending the bottom plate of the recessed area. Furthermore, the water guiding channel area 110 includes a first channel segment and a second channel segment located on both sides of the marking area 11. In the depth direction of the drain outlet 10 (i.e.,...) Figure 2 (In the direction of the extension of the dotted line): One end of the first trough section is connected to the drain outlet 10, and the other end extends away from the central axis of the drain outlet 10 (i.e., Figure 2 The direction of the dotted line in the middle is inclined; one end of the second groove is connected to the drain outlet 10, and the other end is inclined away from the central axis of the drain outlet 10. Thus, the first groove and the second groove form a tapering inverted funnel shape in the drain outlet 10, that is, the connection between the water guide groove area 110 and the drain outlet 10 forms a water guide structure with a small opening and a large capacity. This not only allows for the temporary storage of a large amount of accumulated water and prevents the installation point from being submerged by a large amount of accumulated water, but also allows the accumulated water to be guided to the drain outlet 10 and discharged out of the recessed area in a timely manner.

[0055] Please see Figure 5 In some embodiments, a sealing strip 31 is provided at the sealing connection between the cover plate 3 and the crossbeam 1 along the periphery of the recessed area. This sealing strip 31 breaks at the position corresponding to the outlet of the water guide channel area 110 to form a drain outlet 10, eliminating the need for additional drainage accessories. Specifically, the sealing strip 31 can be made of waterproof foam, and it protrudes from and is fixedly connected to the inner side of the cover plate 3. When the cover plate 3 is installed on the crossbeam 1, the sealing strip 31 can be squeezed to achieve the purpose of sealing the periphery of the recessed area. In specific implementations, the sealing strip 31 can be changed from a whole-piece cutting process to a strip-cutting process, which can reduce production costs. Further, please refer to... Figure 3 In practice, the arrow of the marking area 11 of the protruding structure can be aligned with the drain outlet, and the slope design of the recessed area can make it difficult for the water discharged from the drain outlet 10 to flow back.

[0056] In some embodiments, the drain outlet 10 is located on the first side of the recessed area, and the second side of the recessed area is opposite to the first side. When the crossbeam 1 is installed on the top of the vehicle body, the second side of the recessed area is positioned higher than the first side, thus achieving a slope design for the recessed area, facilitating the automatic flow of accumulated water to the drain outlet 10 and its discharge under gravity. Further, at least the radially outer side of the second side of the recessed area is provided with a water-blocking rib 13 and a sealing strip 31. When the cover plate 1 is installed on the crossbeam 1 to cover the recessed area, the sealing strip 31 is located radially inner to the water-blocking rib 13, meaning the water-blocking rib 13 is further away from the recessed area than the sealing strip 31. Preferably, at least a portion of the water-blocking rib 13 is located on the rear side and both sides of the recessed area, and at least a portion of the sealing strip 31 is located on the rear side and both sides of the recessed area. For example, as... Figure 2 As shown, the water-blocking rib 13 is U-shaped and located outside the first side of the recessed area and the third and fourth sides connected to the two ends of the first side, respectively. It can prevent water from outside the vehicle from entering the recessed area and plays a waterproof role. The sealing strip 31 is arranged around the perimeter of the recessed area and is only broken at the location of the drain outlet 10. In actual implementation, in case of accidents or extreme situations, if water flows through the water-blocking rib 13 and the sealing strip 31 or enters the recessed area by other means, it can also be discharged to the outside of the vehicle through the water guide channel area 110 and the drain outlet 10 mentioned above, so as to avoid the radar mounting point being submerged in water.

[0057] In some embodiments, the radar body described above can be a forward-looking lidar, and the crossbeam 1 is the front roof crossbeam of the vehicle. Furthermore, as... Figure 6 and Figure 7 As shown, the radar body 4 can be screwed into the recessed area of ​​the crossbeam 1 via the bracket 2. After assembly, the radar body 4 is located between the bracket 2 and the cover plate 3. Further, as... Figure 2 and Figure 6 As shown, mounting areas 12 for mounting brackets 2 and radar bodies 4 are respectively provided at the four corners of the recessed area. Because the recessed area has a slope design that is lower in the front and higher in the back, the protrusion height of the two rear mounting areas 12 can be relatively lower than that of the two front mounting areas 12, so that the radar body 4 remains basically horizontal. At this time, a water channel area 110 is formed between the marking area 11 and the mounting areas 12, and also between adjacent mounting areas 12. In specific implementations, at least the two front mounting areas 12 can be designed as a double-tower structure. This double-tower structure includes a first protruding area protruding relative to the bottom surface of the recessed area, and a second protruding area located at the top of the first protruding area and protruding further upwards relative to the first protruding area. The mounting points of brackets 2 and radar bodies 4 are located at the top of the second protruding area, higher than the drainage point of the crossbeam, thus preventing waterlogging and seepage at the mounting points of brackets 2 and radar bodies 4 when water accumulates in the recessed area.

[0058] In some embodiments, the bracket 2 is located above the marking area 11 and connected to the mounting area 12 by fasteners, which may be bolts 5 and nuts 6, as detailed in [reference needed]. Figure 8 In some embodiments, since the crossbeam 1 includes an upper plate 1' and a lower plate 1'", the connection between the bracket 2 and the mounting area 12 is a multi-layer sheet metal structure, resulting in multiple leakage points. For example, there is a first fitting gap a between the bolt 5 and the nut 6, a second fitting gap b between the nut 6 and the bracket 2, and a third fitting gap c between the bracket 2 and the upper plate 1'. Different sealing measures can be selected based on the corresponding structure. For example, a ring-welded nut can be used with a chemically locked bolt, and a waterproof sealing gasket 8 can be added between the bracket 2 and the crossbeam 1 to ensure that the fitting gap between them does not leak. For details, please refer to... Figure 8 Nut 6 is located above bracket 2. The first mating gap a between nut 6 and bolt 5 is sealed by chemical locking adhesive; and / or, the second mating gap b between nut 6 and bracket 2 is sealed by an annular weld 7, i.e., nut 6 is an HP nut with a raised weld point around the entire ring; and / or, a sealing gasket 8 (with an effective coverage of more than 5mm) is provided between the bottom surface of bracket 2 and the top surface of mounting area 12, and the thickness of the sealing gasket 8 can be about 0.5mm. Furthermore, if mounting area 12 is a semi-dry area, bolt 5 may not need a waterproof ring; if mounting area 12 is a wet area, based on its relatively high protrusion position, it is not easy for water to enter, and bolt 5 may also not need a waterproof ring.

[0059] Secondly, this application embodiment also provides a vehicle, the roof of which is provided with the radar area waterproof structure described above. Specifically, the radar body 4 can be a forward-looking lidar, that is, the aforementioned radar area waterproof structure is used to install the forward-looking lidar. In this case, the upper surface of the crossbeam 1 includes a main body area 101 and a side area 102. The main body area 101 is provided with the recessed area described above, and the side area 102 is recessed downward relative to the main body area 101 for connection with the windshield. Moreover, as Figure 3 As shown ( Figure 3 The horizontal dashed line represents the horizontal plane. In the waterproof structure of this radar area, the first side of the drainage outlet 10 in the recessed area is inclined downward at a preset angle f relative to the second side opposite it. The preset angle f is any value within the range of 15° to 45°. That is, the drainage outlet 10 is located on the side with the lowest height in the above-mentioned recessed area to facilitate the automatic drainage of accumulated water.

[0060] Furthermore, it is important to note that in the completed installation of the crossbeam 1, the radar mounting point in the aforementioned recessed area is higher than the drainage point of the crossbeam. That is, the top surface of the mounting area 12 must be at a higher level than the drainage outlet 10 to avoid water immersion at the mounting point. At this point, the radar mounting point is higher than the lowest point of the glass glue side connection of the crossbeam. Through the drainage structure formed by the aforementioned water guide channel area 110 and drainage outlet 10, as well as the marking area 11 with its raised rib structure and the double-tower structure of the mounting area 12, accumulated water entering the recessed area can be drained. The water then flows away from the drainage outlet 10 through the lowest point of the crossbeam side area 102, preventing backflow of water under extreme operating conditions and submerging the mounting point. This ensures that the radar mounting area will not experience long-term water accumulation, leading to the risk of prolonged water immersion and leakage at the mounting point.

[0061] In summary, this application addresses the common problem of water leakage in forward-looking lidar by optimizing the structural surface of the crossbeam 1 and the cover plate 3. This not only seals the recessed area of ​​the upper plate 1' of the crossbeam but also ensures that rainwater or other water entering the recessed area of ​​the radar body 4 is promptly discharged through the water guide channel 110, the drain outlet 10, and the side area 102 of the crossbeam (for details of the drainage path, please refer to...). Figure 2 The arrows (indicated by the direction of the water flow) ensure that rainwater or other water sources cannot accumulate in this area, preventing soaking of the radar mounting point. This creates a perfect wet zone system, minimizing the risk of leakage in the radar mounting area and eliminating concerns about the durability of waterproofing measures, thus completely solving the leakage problem. Furthermore, this radar zone waterproofing structure is suitable for any vehicle model.
