Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted radars, and in particular to a housing component, a vehicle-mounted radar and a vehicle. Background Art

[0002] Cars are often equipped with onboard radar to detect their surroundings. These radars are typically mounted on the roof, protruding from the exterior to prevent obstruction and improve detection. However, at high speeds, airflow directly impacts the radar, generating noise that significantly impacts passenger comfort. Utility Model Content

[0003] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0004] The exterior of an on-board radar is typically fitted with a radome consisting of a radar window and a radome cover. Because the radar window is an optical component and the radome is a plastic part, the radome cannot be manufactured as a single piece. Instead, the radar window and radome cover are two separate components, creating a seam where they meet. The gap formed by the assembly of the radome and radome connects to the inside of the seam. When a vehicle travels at high speeds, pressure fluctuations on the seam surface generate cavity noise within the gap connected to the seam, leading to high wind noise at high speeds.

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, an embodiment of the present invention proposes a shell assembly that can reduce wind noise and improve the passenger experience.

[0007] An embodiment of the present utility model further provides a vehicle-mounted radar.

[0008] An embodiment of the present invention further provides a vehicle.

[0009] The shell assembly of an embodiment of the present utility model includes: a radome, the radome includes a radar window and a radar cover, the radar window is installed on the front side of the radome, the radar window includes a windward portion and a transition portion, the transition portion is provided at the top of the windward portion and gradually extends backward, the rear end face of the transition portion is spliced with the front end face of the radome; a radar shell, the radar shell is provided in the radome and covers the splicing position of the transition portion and the radome cover, and a first sealing layer is provided between the inner wall surface of the transition portion and at least one of the inner wall surface of the front side of the radome cover and the radar shell.

[0010] According to the housing assembly of the embodiment of the present invention, since the transition portion is located at the top of the windward portion and gradually extends rearward, the rear end surface of the transition portion is spliced with the front end surface of the radome. This allows the splicing location of the transition portion and the radome to avoid the windward area of the radar window, thereby reducing the disturbance of the airflow caused by the splicing gap between the transition portion and the radome. In addition, since the radome covers the splicing location of the transition portion and the radome, a first sealing layer is formed between the radome and at least one of the inner wall surface of the transition portion and the inner wall surface of the front side of the radome. This can seal the assembly gap formed between the radome and the radome, avoiding the formation of a gap cavity connected to the splicing location of the transition portion and the radome. This can reduce the cavity noise generated by the housing assembly, reduce wind noise, and enhance the passenger experience.

[0011] In some embodiments, the first sealing layer includes a sealant layer, the outer wall surface of the radar shell is provided with a glue-coated surface, and the sealant layer is provided between the inner wall surface of the transition portion and the glue-coated surface.

[0012] In some embodiments, the splicing position of the transition portion and the radar cover has a splicing gap, and a glue storage groove is provided on the glue coating surface. The glue storage groove is arranged adjacent to the splicing gap and extends along the length direction of the splicing gap.

[0013] In some embodiments, the radar housing is provided with a stop portion protruding toward the transition portion, the outer wall surface of the stop portion constitutes part of the glue coating surface, and the glue storage tank is provided on the outer wall surface of the stop portion.

[0014] In some embodiments, the distance between the glue storage groove and the splicing gap is A, wherein 1mm≤A≤3mm; and / or the depth of the glue storage groove is B, wherein 0.5mm≤B≤1mm.

[0015] In some embodiments, the first sealing layer includes an elastic sealing gasket, which is arranged between the inner wall surface of the front side of the radar cover and the radar shell. The splicing position of the transition part and the radar cover has a splicing gap, and the elastic sealing gasket blocks the lower end of the splicing gap.

[0016] In some embodiments, the outer wall surface of the radar housing has a first groove, and the elastic sealing gasket is installed in the first groove; and / or the elastic sealing gasket is a first sealing foam.

[0017] In some embodiments, the shell assembly also includes a base, on which a second groove is provided, and the lower end of the windward portion and the rear side of the radar cover are both installed in the second groove, and a second sealing layer is provided between at least one of the windward portion and the radar cover and the groove wall of the second groove.

[0021] In another embodiment of the present invention, a vehicle-mounted radar features a transition portion positioned at the top of the windward portion and gradually extending rearward, with the rear end of the transition portion joined to the front end of the radar cover. This allows the transition portion and the radar cover to be joined away from the windward area of the radar window, thereby reducing airflow disturbance caused by the gap between the transition portion and the radar cover. Furthermore, since the radar housing covers the junction of the transition portion and the radar cover, a first sealing layer is formed between the radar housing and at least one of the inner wall of the transition portion and the inner wall of the front side of the radar cover. This seals the assembly gap between the radar cover and the radar housing, preventing the formation of a gap cavity connecting to the junction of the transition portion and the radar cover. This reduces cavity noise generated by the vehicle-mounted radar, reduces wind noise, and enhances the passenger experience.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] Please refer to the following Figures 1 to 6 The present invention is described as follows: a housing assembly, a vehicle-mounted radar and a vehicle according to embodiments of the present invention.

[0038] like Figures 1 to 6As shown, the housing assembly of the embodiment of the present invention includes a radome 1 and a radome shell 2 , and the radome 1 includes a radar window 11 and a radar cover 12 .

[0039] The radar window 11 is installed on the front side of the radar cover 12. The radar window 11 includes a windward portion 111 and a transition portion 112. The transition portion 112 is provided at the top of the windward portion 111 and gradually extends backward. The rear end face of the transition portion 112 is spliced with the front end face of the radar cover 12. The radar shell 2 is provided in the radar cover 1 and covers the splicing position of the transition portion 112 and the radar cover 12. A first sealing layer 4 is provided between the inner wall surface of the transition portion 112 and the inner wall surface of the front side of the radar cover 12 and the radar shell 2.

[0040] It should be noted that the front-to-back directions of the radar window 11 and the radar cover 12 are consistent with the front-to-back directions of the vehicle-mounted radar. It is understood that the radar window 11 is installed on the front side of the vehicle-mounted radar so that the radar body inside the vehicle-mounted radar can detect the external environment through the radar window 11.

[0041] For example, when a vehicle-mounted radar is mounted on a vehicle roof and is configured to detect the environment in front of the vehicle, the front-to-back direction of the vehicle-mounted radar is consistent with the actual front-to-back direction of the vehicle.

[0042] According to the shell assembly of the embodiment of the present utility model, since the transition portion 112 is provided at the top end of the windward portion 111 and gradually extends backward, the rear end face of the transition portion 112 is spliced with the front end face of the radar cover 12, so that the splicing position of the transition portion 112 and the radar cover 12 can avoid the windward area of the radar window 11, so as to reduce the disturbance of the airflow caused by the splicing gap 13 between the transition portion 112 and the radar cover 12.

[0043] It is understood that the windward area of the radar window 11 is the front end of the windward portion 111. Because the transition portion 112 is located at the top of the windward portion 111 and gradually extends rearward, the junction between the transition portion 112 and the radome 12 can be positioned away from the windward area of the radar window 11. In other words, the junction between the transition portion 112 and the radome 12 is located at the top of the radome 1, forming a "ceiling-facing seam" structure.

[0044] Since the radar shell 2 covers the splicing position of the transition part 112 and the radar cover 12, a first sealing layer 4 is provided between the radar shell 2 and at least one of the inner wall surface of the transition part 112 and the inner wall surface of the front side of the radar cover 12, thereby the assembly gap formed between the radar cover 1 and the radar shell 2 can be sealed to avoid the formation of a gap cavity connected to the splicing gap 13 (the splicing position of the transition part 112 and the radar cover 12), thereby reducing the cavity noise generated by the shell assembly, reducing wind noise, and improving the passenger experience.

[0045] Among them, “a first sealing layer 4 is provided between at least one of the inner wall surface of the transition portion 112 and the inner wall surface of the front side of the radar cover 12 and the radar housing 2” includes the following three situations:

[0046] (1) If Figure 3 As shown, the first sealing layer 4 is provided between the inner wall surface of the transition portion 112 and the outer wall surface of the radar housing 2, and the first sealing layer 4 is arranged adjacent to the joint position of the transition portion 112 and the radar housing 2 to seal the gap cavity generated by the assembly of the transition portion 112 and the radar housing 2.

[0047] (2) The first sealing layer 4 is provided between the inner wall surface of the front side of the radar cover 12 and the outer wall surface of the radar shell 2, and the first sealing layer 4 is arranged adjacent to the splicing position of the transition portion 112 and the radar shell 2 to seal the gap cavity generated by the assembly of the radar cover 12 and the radar shell 2.

[0048] (3) If Figure 4 As shown, part of the first sealing layer 4 is arranged between the inner wall surface of the front side of the radar cover 12 and the outer wall surface of the radar shell 2, and the other part of the first sealing layer 4 is arranged between the inner wall surface of the front side of the radar cover 12 and the outer wall surface of the radar shell 2, and the first sealing layer 4 is arranged adjacent to the splicing position of the transition portion 112 and the radar shell 2, thereby sealing the gap cavity generated by the assembly of the radar cover 1 (radar window 11 and radar cover 12) and the radar shell 2.

[0049] Alternatively, as Figures 2 to 4 As shown, the first sealing layer 4 includes a sealant layer 41. The outer wall of the radar housing 2 is provided with a glue-coated surface 21, and the sealant layer 41 is disposed between the inner wall of the transition portion 112 and the glue-coated surface 21. It will be appreciated that the transition portion 112 of the radar window 11 is bonded and fixed to the radar housing 2. Since the transition portion 112 and the radar housing 2 are bonded and fixed using a sealant coating, the radar window 11 and the radar housing 2 are both secured and sealed, preventing cavity noise from the housing assembly.

[0050] In one example, if Figure 3 and Figure 4 As shown, the joint between the transition portion 112 and the radar cover 12 has a joint gap 13, and the glue-applied surface 21 is provided with a glue reservoir 23, which is arranged adjacent to the joint gap 13 and extends along the length of the joint gap 13. When the transition portion 112 is bonded to the radar cover 2, excess sealant overflows into the sealant reservoir 23, thereby reducing the probability of the sealant overflowing outside the radar window 11.

[0051] It is understandable that because the gap of the joint gap 13 is typically designed to be narrow, if the sealant overflows outside the radar window 11 (i.e., the side of the radar window 11 adjacent to the joint gap 13), the solidified sealant will interfere with the installation of the radome 12. On the one hand, this will cause the radome 1 to be improperly assembled, and on the other hand, the sealant overflow problem will also affect the aesthetic appearance of the radome 1.

[0052] The shell assembly of the embodiment of the present invention can receive excess glue when the radar window 11 is bonded by providing a glue storage tank 23, so as to reduce the probability of the sealant overflowing to the outside of the radar window 11, and the glue in the glue storage tank 23 will also be bonded to the radar window 11 after solidification, thereby sealing the gap cavity generated by the assembly of the transition portion 112 and the radar shell 2, so as to reduce the problem of air noise of the vehicle-mounted radar.

[0053] Alternatively, as Figure 3 and Figure 4 As shown, the radar housing 2 is provided with a stopper 22 protruding toward the transition portion 112. The outer wall surface of the stopper 22 constitutes at least a portion of the glue-coated surface 21, and a glue storage tank 23 is provided on the outer wall surface of the stopper 22. It is understandable that a portion of the glue-coated surface 21 is formed on the outer wall surface of the stopper 22, and another portion of the glue-coated surface 21 is formed in front of the stopper 22. When the transition portion 112 of the radar window 11 is bonded to the radar housing 2, the glue in front of the stopper 22 can be stopped by the stopper 22 to prevent excess glue from flowing toward the splicing gap 13, further reducing the problem of glue overflow between the radar window 11 and the radar housing 2.

[0054] like Figure 3 and Figure 4 As shown, when applying glue to the glue-coated surface 21, a first layer of sealant 411 can be applied in front of the stopper 22 to ensure a secure bond between the radar window 11 and the radar housing 2. This facilitates controlling the amount of sealant 411 dispensed, preventing it from overflowing toward the front or rear of the transition portion 112. A second layer of sealant 412 is then applied to the outer wall of the stopper 22 (inside the glue reservoir 23). This second layer of sealant 412 seals the gap created by the assembly of the transition portion 112 and the radar housing 2, thereby reducing airborne noise from the vehicle-mounted radar.

[0055] Optionally, the distance A between the glue reservoir 23 and the joint gap 13 is 1 mm ≤ A ≤ 3 mm. For example, the distance A between the glue reservoir 23 and the joint gap 13 can be 1 mm, 2 mm, or 3 mm. The inventors of this application have found through experimental research that when the distance A between the glue reservoir 23 and the joint gap 13 is within the above numerical range, it can prevent glue from overflowing into the joint gap 13 while also sealing the gap created by the assembly of the transition portion 112 and the radar housing 2, resulting in a better performance.

[0056] The depth of the glue storage tank 23 is B, where 0.5 mm ≤ B ≤ 1 mm. For example, the depth B of the glue storage tank 23 can be 0.5 mm, 0.75 mm, or 1 mm. In the example of the present application, the cross-section of the glue storage tank 23 is semicircular with a radius of 0.75 mm. This allows the glue storage tank 23 to store excess glue while minimizing the impact on the structural strength of the radar housing 2.

[0057] It should be noted that the distance A between the glue storage tank 23 and the splicing gap 13 and the depth B of the glue storage tank 23 can also be designed according to the different shapes and sizes of the vehicle-mounted radar, and this application does not limit this.

[0058] For example, the width of the splicing gap 13 is C, where 0.5 mm ≤ C ≤ 1.5 mm. The width C of the splicing gap 13 can be 0.5 mm, 1 mm, or 1.5 mm. This ensures that the proper assembly of the radar window 11 and radar cover 12 is not affected, while also reducing the wind noise caused by an excessively wide splicing gap 13.

[0059] In some embodiments, the first sealing layer 4 includes an elastic sealing gasket 42, which is disposed between the inner wall surface of the front side of the radar cover 12 and the radar housing 2. The elastic sealing gasket 42 blocks the lower end of the splicing gap 13. It will be understood that the elastic sealing gasket 42 can not only seal the gap cavity between the inner wall surface of the front side of the radar cover 12 and the radar housing 2, but also seal the lower end of the splicing gap 13, thereby further reducing the noise problem generated by the gaps and cavities formed when the radar window 11, radar cover 12, and radar housing 2 are assembled.

[0060] Optionally, the outer wall surface of the radar shell 2 has a first groove 24, and the elastic sealing gasket 42 is installed in the first groove 24. It can be understood that the first groove 24 can not only limit and fix the elastic sealing gasket 42, but also form an avoidance structure for the installation of the elastic sealing gasket 42 to prevent the front end position of the assembled radar cover 12 from being too high.

[0061] For example, the elastic sealing pad 42 is a first sealing foam 421, which can be compressed. The radar cover 12 is snap-fitted to the radar housing 2, and the snap-fitted radar cover 12 compresses the first sealing foam 421, thereby ensuring the sealing effect between the radar cover 12 and the radar housing 2.

[0062] In some embodiments, the housing assembly further includes a base 3 having a second trough 31 defined thereon. The lower end of the windward portion 111 and the rear side of the radome 12 are both mounted within the second trough 31. A second sealing layer 5 is provided between at least one of the windward portion 111 and the radome 12 and the walls of the second trough 31. For example, the second sealing layer 5 is provided between both the windward portion 111 and the radome 12 and the walls of the second trough 31. This improves the sealing effect between the radome 1 and the base 3, preventing noise caused by airflow suction at the assembly point of the radome 1 and the base 3 when the vehicle is traveling at high speeds.

[0063] Through experimental research, the inventors of this application discovered that without the second sealing layer 5 at the assembly point between the radome 1 and the base 3, a clear gap exists between them. This gap can generate suction noise during high-speed vehicle travel. Simply adding a sealing lip between the radome 1 and the base 3 would compromise the aesthetics of the design, while directly adding a foam seal would expose the foam.

[0064] Therefore, the shell assembly of the embodiment of the present invention can avoid the problem of leakage of the second sealing layer 5 by setting a second groove 31 on the base 3 and setting a second sealing layer 5 between the groove walls of the second groove 31, and can reduce the problem of wind noise generated at the assembly position of the radar cover 1 and the base 3.

[0065] Specifically, the second sealing layer 5 also includes a second sealing foam 51 and a third sealing foam 52. The second sealing foam 51 is disposed between the lower end surface of the windward portion 111 and the bottom wall of the second sink 31, while the third sealing foam 52 is disposed between the lower end surface of the radar cover 12 and the bottom wall of the second sink 31. After assembly, the second and third sealing foams 51, 52 are compressed to form a sealed structure. This prevents the second and third sealing foams 51, 52 from leaking out and affecting the appearance, while also addressing wind noise.

[0066] In addition, compared with the solution of setting the second sealing layer 5 as an adhesive layer, the solution of the present application setting the second sealing layer 5 as a second sealing foam 51 and a third sealing foam 52 can reduce the force exerted by the adhesive structure on the radar window 11 and the radar cover 12, thereby avoiding the problem of deformation of the radar window 11 and the radar cover 12 during bonding and curing.

[0067] In order to improve the reliability of the crimping between the radar cover 12 and the third sealing foam 52, a fixing rib 121 is provided at a position of the radar cover 12 adjacent to the second sinking groove 31. The fixing rib 121 is located on the inner side of the edge of the radar cover 12 and abuts against the third sealing foam 52, thereby further improving the reliability of the sealing between the radar cover 12 and the base 3.

[0068] Optionally, the upper edge of the rear end surface of the transition portion 112 is not lower than the upper edge of the front end surface of the radar cover 12, thereby reducing the disturbance of the airflow caused by the splicing position of the transition portion 112 and the radar cover 12, and reducing the problem of resonance noise generated at the splicing position of the transition portion 112 and the radar cover 12.

[0069] In the example of this application, the height of the radar cover 12 gradually decreases from front to back. This can reduce wind resistance and reduce the impact of the vehicle-mounted radar on the vehicle's speed. For example, the outer structure of the radar cover 1 can be a pebble-like structure.

[0070] A vehicle-mounted radar according to another embodiment of the present invention includes a housing assembly and a radar body (not shown). The housing assembly is the housing assembly of the embodiment of the present invention, and the radar body is disposed in a radar housing 2 .

[0071] In another embodiment of the vehicle-mounted radar of the present invention, the transition portion 112 is provided at the top of the windward portion 111 and gradually extends rearward. The rear end surface of the transition portion 112 is spliced with the front end surface of the radar cover 12. This allows the splicing location of the transition portion 112 and the radar cover 12 to avoid the windward area of the radar window 11, thereby reducing the disturbance of the airflow caused by the splicing gap 13 between the transition portion 112 and the radar cover 12. In addition, because the radar housing 2 covers the splicing location of the transition portion 112 and the radar cover 12, a first sealing layer 4 is formed between the radar housing 2 and at least one of the inner wall surface of the transition portion 112 and the inner wall surface of the front side of the radar cover 12. This seals the assembly gap formed between the radome 1 and the radar housing 2, avoiding the formation of a gap cavity connected to the splicing location of the transition portion 112 and the radar cover 12. This reduces the cavity noise generated by the vehicle-mounted radar, reduces wind noise, and improves the passenger experience.

[0072] Another embodiment of the present invention includes a vehicle housing assembly or a vehicle-mounted radar of the present invention. The technical advantages of the vehicle of the embodiment of the present invention are the same as those of the housing assembly and the vehicle-mounted radar of the above embodiment, and are not further described here.
