Description

Technical Field

[0001] This utility model relates to the field of automotive radar installation technology, and in particular to a waterproof assembly structure, a radar cover mounting structure having the same, and an automobile. Background Technology

[0002] With the continuous development of the automotive industry in recent years, the demand for intelligent driving is increasing. Adding LiDAR is commonly used to improve intelligent driving capabilities. This requires the simultaneous addition of a LiDAR cover to mount the LiDAR on the vehicle. The LiDAR cover is typically connected to the sheet metal above the driver's cab, ensuring that the LiDAR units are positioned on the upper side of the cab.

[0003] In traditional lidar cover assembly structures, the lidar cover is fastened to the automotive sheet metal using clips. This installation method requires drilling mounting holes in the automotive sheet metal for the clips to pass through and secure them to the sheet metal. The clips also connect to the lidar cover to keep the clips, automotive sheet metal, and lidar cover relatively fixed. In this case, since the automotive sheet metal has mounting holes, waterproofing needs to be considered.

[0004] Currently, the sealing method for this structure involves placing a sealing element around the side of the clip facing the automotive sheet metal. When the clip connects to the mounting hole in the automotive sheet metal, the sealing element seals the mounting hole, preventing external water from seeping into the vehicle interior. However, during the manufacturing process, the sealing element may deform due to uncontrolled processes, failing to effectively seal the mounting hole in the automotive sheet metal and leading to water leakage inside the vehicle. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a waterproof assembly structure and a radar cover mounting structure and automobile having the same, which can ensure the sealing effect at the mounting holes of the automobile sheet metal.

[0006] This utility model provides a waterproof assembly structure, including a base, the base having an assembly surface, a connector being provided in the middle of the assembly surface of the base, the connector being used to keep the base relatively fixed to an external object; a plurality of sealing elements surrounding the connector are provided at intervals on the assembly surface of the base, the sealing elements extending in a direction away from the assembly surface, and the sealing elements being elastic bodies.

[0007] Optionally, among the plurality of seals, the seals that are further away from the connector have a longer extension length toward the mounting surface in a direction that gradually moves away from the connector.

[0008] Optionally, the seal is inclined in a direction away from the connector, and among the plurality of seals, the seal that is further away from the connector in the direction gradually moving away from the connector has a larger angle with the normal of the assembly surface.

[0009] Optionally, the connector includes a body portion and a snap-fit ​​portion. The body portion has a first end and a second end opposite to each other. The first end of the body portion is connected to the mounting surface of the base, and the second end of the body portion extends in a direction away from the mounting surface. One end of the snap-fit ​​portion is connected to the second end of the body portion, and the other end of the snap-fit ​​portion extends in a plane where the mounting surface is located. The included angle between the snap-fit ​​portion and the body portion is an acute angle.

[0010] Optionally, the outer side of the snap-fit ​​portion away from the body portion includes a first connecting surface and a second connecting surface connected in a direction gradually away from the mounting surface. The first connecting surface extends away from the body portion, and the second connecting surface extends towards the body portion. The connection between the first connecting surface and the second connecting surface is a curved surface.

[0011] Optionally, a reinforcing portion is formed on the opposite surface of the outer side of the snap-fit ​​portion, the reinforcing portion extends toward the body portion, and a cavity is formed within the reinforcing portion.

[0012] Optionally, one side of the snap-fit ​​portion has an extension portion, and the snap-fit ​​portion is connected to the main body portion through the extension portion.

[0013] Optionally, the base and the connector are plastic parts, and the seal and the base are made by secondary injection molding.

[0015] This utility model also provides an automobile, including the waterproof assembly structure as described above or the radar cover mounting structure as described above.

[0016] The beneficial effects of this utility model are as follows: by setting multiple sealing rings on the mounting surface of the base, when the connector passes through the mounting hole of the automotive sheet metal to connect the sheet metal and the base together, the mounting hole on the sheet metal is sealed by multiple sealing rings. Even if one of the sealing rings fails due to process problems and cannot seal the mounting hole, the sealing effect can be guaranteed by other sealing rings to ensure the sealing performance.

[0036] like Figures 1 to 3As shown, this embodiment provides a waterproof assembly structure, including a base 10. The base 10 has an assembly surface 11, and a connector 20 is provided in the middle of the assembly surface 11. The connector 20 extends in a direction away from the assembly surface 11. In some embodiments, the connector 20 is vertically disposed on the assembly surface 11 of the base 10. The connector 20 is used to keep the base 10 relatively fixed to an external object. Specifically, in this embodiment, the connector 20 is used to keep the base 10 and the automotive sheet metal relatively fixed. An assembly groove 12 is formed along the side wall of the base 10. The assembly groove 12 is used to connect with a lidar cover plate, so that the base 10 and the lidar cover plate are relatively fixed, thereby keeping the base 10, the automotive sheet metal, and the lidar cover plate relatively fixed. Two sealing elements 30, namely a first sealing element 31 and a second sealing element 32, are provided at intervals around the connecting element 20 on the mounting surface 11 of the base 10. The first sealing element 31 is closer to the connecting element 20, while the second sealing element 32 is further away from the connecting element 20 than the first sealing element 31. The first sealing element 31 and the second sealing element 32 extend on the mounting surface 11 of the base 10 in a direction away from the mounting surface 11. Specifically, the first sealing element 31 and the second sealing element 32 are both cylindrical structures, with one end connected to the mounting surface 11. The sealing element 30 is an elastomer made of TPE (synthetic rubber). When the connector 20 on the base 10 is connected to the automotive sheet metal, the seal 30 abuts against the automotive sheet metal. As the seal 30 gradually approaches the automotive sheet metal, it deforms to seal the mounting holes on the sheet metal. Since the seal 30 is an elastic body, it generates a rebound force after deformation due to its own elasticity, which firmly abuts the seal 30 against the automotive sheet metal. The base 10 and connector 20 are plastic parts made of POM (polyoxymethylene resin). The seal 30 and base 10 are manufactured using a secondary injection molding process. Figure 2 For ease of distinction, the base 10 and the seal 30 are depicted as separate structures, but in reality they are an integrated structure.

[0037] The waterproof assembly structure provided in this embodiment provides multiple sealing elements 30 spaced around the connecting member 20. When one of the sealing elements 30 does not meet the usage requirements due to the manufacturing process, the mounting holes on the automotive sheet metal can be sealed by other sealing elements 30 that meet the usage requirements. Compared with only one ring of sealing elements 30, it has a larger tolerance and avoids the problem of water leakage in the car as much as possible due to sealing failure.

[0038] Furthermore, among the multiple seals 30, in the direction gradually moving away from the connector 20, the seal 30 further away from the connector 20 has a longer extension length towards the mounting surface 11, that is, the seal 30 further away from the connector 20 has a longer length. Corresponding to this embodiment, the length of the second seal 32 is greater than the length of the first seal 31. The purpose of this arrangement is to prevent interference between the first seal 31 and the second seal 32 as they gradually approach the automotive sheet metal, thus preventing effective sealing of the automotive sheet metal. Specifically, during the process of the base 10 connecting to the automotive sheet metal through the connector 20, the connector 20 on the base 10 gradually penetrates into the mounting hole of the automotive sheet metal. At this time, the seal 30 on the mounting surface 11 of the base 10 also gradually approaches the automotive sheet metal. After the seal 30 contacts the automotive sheet metal, it begins to deform, and the extension direction of the seal 30 changes to be flush with the surface of the automotive sheet metal. If the length of the first seal 31 is greater than the length of the second seal 32, after the first seal 31 and the second seal 32 come into contact with and deform against the automotive sheet metal, the first seal 31, due to its longer length, may come into contact with the second seal 32 from below, causing the second seal 32 to be lifted up and unable to achieve a sealing effect. Therefore, the length of the first seal 31 is set to be less than the length of the second seal 32, so that they will not come into contact with each other during the deformation process after they come into contact with the automotive sheet metal, thereby avoiding the problem of mutual interference affecting the sealing effect.

[0039] Meanwhile, both the first seal 31 and the second seal 32 are inclined away from the connector 20, allowing them to extend smoothly away from the connector 20 and flush with the surface of the automotive sheet metal when in contact with it. If the seal 30 were not inclined, it might bend towards the connector 20 when in contact with the sheet metal, resulting in a poor sealing effect. Furthermore, in the direction gradually moving away from the connector 20, the angle between the seal 30 and the normal to the assembly surface 11 is larger for the seal 30 further away from the connector 20. That is, when the two seals 30 are not in contact with the automotive sheet metal, the angle between the second seal 32 and the normal to the assembly surface 11 is greater than the angle between the first seal 31 and the normal to the assembly surface 11. This design is also to avoid mutual interference when the two seals 30 deform after contacting the automotive sheet metal.

[0040] For the connector 20 on the base 10, such as Figure 1 and Figure 2As shown, the connector 20 includes a body portion 21 and a snap-fit ​​portion 22. The body portion 21 has a first end and a second end. The first end of the body portion 21 is connected to the mounting surface 11 of the base 10, and the second end of the body portion 21 extends away from the mounting surface 11. One end of the snap-fit ​​portion 22 is connected to the second end of the body portion 21, and the other end of the snap-fit ​​portion 22 extends towards the plane where the mounting surface 11 is located. The angle between the snap-fit ​​portion 22 and the body portion 21 is an acute angle, that is, the other end of the snap-fit ​​portion 22 gradually moves away from the body portion 21. The snap-fit ​​portion 22 is arranged at an angle on the body portion 21, which allows the snap-fit ​​portion 22 to be appropriately deformed around the second end of the body portion 21 and to swing. The outer surface of the snap-fit ​​portion 22 away from the main body portion 21 includes a first connecting surface 221 and a second connecting surface 222 connected in a direction that gradually moves away from the mounting surface 11. The first connecting surface 221 extends in a direction away from the main body portion 21, and the second connecting surface 222 extends in a direction close to the main body portion 21. That is, the first connecting surface 221 and the second connecting surface 222 form a curved surface. When connecting the base 10 and the automotive sheet metal via the connector 20, the second end of the body portion 21 of the connector 20 first enters the mounting hole of the automotive sheet metal. As the connector 20 gradually penetrates deeper into the mounting hole of the automotive sheet metal, the snap-fit ​​portion 22, which is inclinedly arranged on the body portion 21, contacts the hole wall of the mounting hole of the automotive sheet metal. Since the diameter of the mounting hole of the automotive sheet metal does not change, and the snap-fit ​​portion 22 is inclined, as the connector 20 gradually penetrates deeper into the mounting hole of the automotive sheet metal, the snap-fit ​​portion 22 deforms appropriately inward to match the diameter of the mounting hole of the automotive sheet metal, causing the snap-fit ​​portion 22 to gradually approach the body portion 21. As the connector 20 is pushed deeper, the second connecting surface 222 of the outer side of the snap-fit ​​part 22 completely passes through the mounting hole of the automotive sheet metal. Then, the first connecting surface 221 of the outer side of the snap-fit ​​part 22 contacts the wall of the mounting hole in the automotive sheet metal. Since the first connecting surface 221 and the second connecting surface 222 are inclined in opposite directions, the pushing force of the mounting hole on the snap-fit ​​part 22 gradually decreases, and the deformation of the snap-fit ​​part 22 gradually recovers. At this time, as the connector 20 is pushed deeper, the base 10 also moves closer to the automotive sheet metal along with the connector 20. As the base 10 gradually approaches the automotive sheet metal, the two seals 30 on the mounting surface 11 of the base 10 abut against the surface of the automotive sheet metal. This causes the two sides of the automotive sheet metal to be limited by the snap-fit ​​part 22 and the base 10 or the seals 30 on the base 10, keeping the connector 20 relatively fixed to the automotive sheet metal. When it is necessary to separate the base 10 from the automotive sheet metal, move the base 10 away from the automotive sheet metal so that the first connecting surface 221 on the outer side of the connector 20 contacts the wall of the mounting hole of the automotive sheet metal. During the process of the snap-fit ​​part 22 deforming around the body part 21, the mounting hole of the automotive sheet metal passes the first connecting surface 221 and the base 10 can be removed from the automotive sheet metal.To facilitate the installation holes of the automotive sheet metal to pass over the connection between the first connecting surface 221 and the second connecting surface 222, the connection between the first connecting surface 221 and the second connecting surface 222 is a curved surface.

[0041] In this embodiment, there are two snap-fit ​​parts 22, which are symmetrically distributed on the main body 21 and have opposite orientations.

[0042] Meanwhile, to prevent the snap-fit ​​part 22 from deforming too easily and causing the base 10 to detach from the car body when the vehicle is bumpy, a reinforcing part 223 is formed on the opposite surface of the outer side of the snap-fit ​​part 22. The reinforcing part 223 extends towards the main body part 21, making the snap-fit ​​part 22 stronger and less prone to deformation under external force, thus preventing the snap-fit ​​part 22 from easily detaching from the car body. A cavity 2231 is formed inside the reinforcing part 223, which can appropriately reduce the weight of the connector 20 and the production cost.

[0043] Furthermore, an extension portion 23 extends from one side of the snap-fit ​​portion 22, and the snap-fit ​​portion 22 is connected to the main body portion 21 through the extension portion 23. By connecting the snap-fit ​​portion 22 and the main body portion 21 through the extension portion 23, the connection between the snap-fit ​​portion 22 and the main body portion 21 can be strengthened, making the snap-fit ​​portion 22 less prone to swaying deformation due to a small force, i.e., the second end relative to the main body portion 21, and preventing the base 10 from falling off the car sheet metal due to bumps during car operation.

[0044] In summary, the waterproof assembly structure provided in this embodiment, by incorporating multiple sealing elements 30, can effectively seal the mounting holes of the automotive sheet metal, preventing the sealing of these holes from failing due to the failure of the sealing elements 30. Furthermore, it provides a secure connection to the automotive sheet metal during assembly, preventing the waterproof assembly structure from detaching from the sheet metal.

[0045] like Figures 4 to 7 As shown, Figure 4 This is a schematic diagram of the radar cover mounting structure in this embodiment. Figure 6 for Figure 4For ease of structural demonstration, the structural diagram of the automotive sheet metal 40 has been omitted. This embodiment also provides a radar cover mounting structure, including a lidar cover 50, an automotive sheet metal 40, and a waterproof assembly structure as described above. One surface of the lidar cover 50 is provided with a radar mounting position and an assembly block 51. The assembly block 51 of the lidar cover 50 matches the assembly groove 12 of the base 10 to keep the lidar cover 50 and the base 10 relatively fixed. The lidar cover 50 is connected to the assembly groove 12 of the base 10 via the assembly block 51 on the surface facing the automotive sheet metal 40, allowing the opposite side of the lidar cover 50 to be a flat plane. This side of the lidar cover 50 is the exterior display surface of the car, achieving an aesthetic effect and preventing the base 10 from being exposed to the outside of the car, thus preventing corrosion or damage to the base 10 and affecting the sealing effect of the waterproof assembly structure on the automotive sheet metal 40. The automotive sheet metal 40 has mounting holes, and the connector 20 passes through the mounting holes of the automotive sheet metal 40 to keep the connector 20 and the automotive sheet metal 40 relatively fixed.

[0046] In summary, the radar cover mounting structure provided in this embodiment can install a lidar and maintain a good seal while being securely connected to the automotive sheet metal 40, and also has a good aesthetic effect.

[0047] This embodiment also provides a vehicle, including a waterproof assembly structure as described above or a radar cover mounting structure as described above.

[0048] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
