Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a radar mounting structure and a vehicle including the radar mounting structure. Background Technology

[0002] In vehicles, radar is an indispensable component of autonomous driving systems or advanced driver assistance systems. Scanning the driving environment with radar effectively enhances driving safety. Currently, radar is being installed on the roof of vehicles to extend the scanning range. In related technologies, a mounting slot is typically created in the roof panel, the radar is placed into the slot, and fixed to the roof panel with a bracket. The radar and bracket are connected and secured using bolts that penetrate the roof panel, and then a cover plate is used to protect the radar. However, rainwater can still enter through the radar viewing window on the cover plate and accumulate between the cover plate and the roof panel in the mounting slot. This can then easily leak through the bolt mounting holes, corroding the roof, causing mold growth in the headliner, and even damaging electrical components within the headliner. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a radar mounting structure that, while firmly fixing the radar to the vehicle body, solves the problem of rainwater leaking from the bolt mounting holes of the roof mounting plate and polluting the roof.

[0004] This application provides a radar mounting structure, including a radar, an outer cover plate, and a roof mounting plate;

[0005] The radar is connected and fixed to the inside of the outer cover plate via a connecting structure, and the scanning end of the radar is aligned with the viewing window of the outer cover plate; the outer cover plate and the roof mounting plate enclose and form an installation space to accommodate the radar, so as to cover the radar on the roof mounting plate.

[0006] The bottom of the radar is spaced apart from the roof mounting plate, and the mounting space is provided with a drainage structure that connects to the outside.

[0007] In one possible implementation, a seal is provided between the outer cover and the roof mounting plate, the seal being arranged circumferentially around the mounting space, and a portion of the seal having a water-guiding notch connecting the outside to the mounting space.

[0008] In one possible implementation, the seal includes a front sealing strip located near the windshield, with the water-guiding notch disposed on the front sealing strip.

[0009] In one possible implementation, a water channel is provided on the side of the roof mounting plate near the windshield, the water channel is arranged along the width direction of the vehicle body, and the water guide notch is connected to the water channel.

[0010] In one possible implementation, the roof mounting plate is inclined in a local area forming the mounting space, and the height of the local area on the vehicle body gradually decreases along the direction gradually approaching the windshield.

[0011] In one possible implementation, the tilt angle of the local region is θ, where 10° ≥ θ ≥ 5°;

[0012] And / or, the roof mounting plate is provided with a mounting groove recessed into the vehicle compartment, the mounting groove accommodating the radar and the bottom wall of the groove forming the inclined local area.

[0013] In one possible implementation, the connection structure includes protrusions disposed on the inner side of the outer cover plate, the protrusions being distributed at least on both sides of the viewing window, and connecting plates being disposed on both sides of the radar, the connecting plates being connected to the protrusions.

[0014] In one possible implementation, the outer cover plate is further provided with a positioning and engaging structure that is spaced opposite to the viewing window, the positioning and engaging structure being used to lock the end of the radar opposite to the viewing window.

[0015] In one possible implementation, the positioning and engaging structure includes a positioning post disposed on the outer cover plate. The positioning post has a first inclined surface and a second inclined surface on the side facing the window. The inclination angle of the first inclined surface is greater than that of the second inclined surface. The first inclined surface is used for the end of the radar to slide into the second inclined surface, and the second inclined surface is used to abut against the end of the radar.

[0016] This application also provides a vehicle including the radar mounting structure as described in any of the preceding claims.

[0017] The radar mounting structure provided in this application fixes the radar to the outer cover plate via a connecting structure, creating a gap between the radar and the roof mounting plate. This is equivalent to the radar being suspended and fixed to the outer cover plate, without any connection to the roof mounting plate or roof sheet metal. No bolts are needed to thread through the roof sheet metal. Even if rainwater enters the mounting space through the gap in the window on the outer cover plate, it will not leak from the roof sheet metal, effectively preventing rainwater from entering the vehicle and contaminating the roof. Simultaneously, the mounting space is equipped with a drainage structure, and the gap between the radar and the roof mounting plate prevents rainwater from being blocked. Rainwater entering the mounting space can flow along the roof mounting plate and be discharged promptly, effectively avoiding the risk of rainwater accumulation in the mounting space or on the roof mounting plate, which could cause adverse effects.

[0028] 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.

[0029] Please refer to the attached document. Figure 1-5 This application provides a radar 2 mounting structure, including a radar 2, an outer cover plate 1, and a roof mounting plate 3; the roof mounting plate 3 refers to the outer roof covering plate, such as the roof sheet metal, specifically the front crossbeam of the roof. The radar 2 is connected and fixed to the inner side of the outer cover plate 1 (the side facing the roof mounting plate 3) via a connecting structure. The scanning end of the radar 2 is aligned with the viewing window 101 of the outer cover plate 1, for example, the scanning end of the radar 2 is inserted into the viewing window 101. The outer cover plate 1 is connected to the roof mounting plate 3 and together with the roof mounting plate 3, forms an installation space to accommodate the radar 2. Thus, the radar 2 is set within the installation space enclosed by the outer cover plate 1 and the roof mounting plate 3. The outer cover plate 1 covers the radar 2 on the roof mounting plate 3, and only the scanning end of the radar 2 is exposed through the viewing window 101, thereby protecting the radar 2 and ensuring that the radar 2 can scan the environment normally.

[0030] Meanwhile, radar 2 is fixed to the outer cover plate 1 and is spaced apart from the roof mounting plate 3. This means radar 2 is essentially suspended within the mounting space and has no connection to the roof mounting plate 3; therefore, there is no need for connection holes or screws on the roof mounting plate 3. Furthermore, the mounting space is equipped with a drainage structure that connects to the outside environment to drain any water that enters the mounting space.

[0031] With this configuration, radar 2 is fixed to the outer cover plate 1 via a connecting structure and is spaced apart from the roof mounting plate 3. This means radar 2 is suspended within the installation space and has no connection to the roof mounting plate 3, or the roof sheet metal. No bolts are needed to connect to the roof sheet metal. Even if rainwater enters the installation space through the gap in the viewing window 101 on the outer cover plate 1, it will not leak from the roof sheet metal, effectively preventing rainwater from entering the vehicle and contaminating the roof. Simultaneously, the installation space is equipped with a drainage structure that connects to the outside, allowing water entering the installation space to drain out. Furthermore, the space between radar 2 and the roof mounting plate 3 prevents rainwater from being blocked, allowing rainwater entering the installation space to flow smoothly along the roof mounting plate 3 and quickly drain out through the drainage structure. This effectively avoids the risk of rainwater accumulating in the installation space or on the roof mounting plate 3, thus preventing adverse effects.

[0032] The outer cover 1 can be connected to the roof mounting plate 3 via an external connection structure such as a snap-fit ​​structure, a magnetic structure, or an adhesive bonding method. Preferably, the outer cover 1 can be connected to the roof mounting plate 3 via a snap-fit ​​structure. This ensures the stability of the connection between the outer cover 1 and the roof mounting plate 3, and also facilitates the disassembly of the outer cover 1 for inspection and maintenance of the radar 2.

[0033] Specifically, the drainage structure can include a seal between the outer cover plate 1 and the roof mounting plate 3. This seal surrounds the installation space circumferentially to seal it, preventing excessive rainwater from entering and damaging the radar 2. Simultaneously, the seal has a partial water-guiding gap 401 connecting the outside to the installation space; that is, the seal does not completely seal the installation space circumferentially, leaving a gap. For example, the height of the water-guiding gap 401 in the vehicle height direction is lower than the height of the rest of the seal. Thus, when rainwater accumulates in the installation space, it can flow along the roof mounting plate 3 to the water-guiding gap 401 for rapid drainage.

[0034] Specifically, the sealing element includes a front sealing strip 4 located near the windshield, and a water guide notch 401 is provided on the front sealing strip 4. The closer to the windshield, the smaller the height of the roof. Relative to the installation space, placing the water guide notch 401 on the front sealing strip 4 will make the water guide notch 401 low, which is conducive to the rapid drainage of rainwater entering the installation space.

[0035] Preferably, the water guide notch 401 can be located in the middle of the front sealing strip 4 in the vehicle width direction.

[0036] Furthermore, a gap can be provided between the radar 2 and the roof mounting plate 3, that is, the radar 2 is not placed on the roof mounting plate 3, but is suspended or connected to the outer cover plate 1. By setting a gap between the radar 2 and the roof mounting plate 3, water entering the installation space can quickly flow along the roof mounting plate 3 to the water guide gap 401 through the gap, and quickly flow out of the installation space where the radar 2 is located from the water guide gap 401.

[0037] In some embodiments, a water channel may be provided on the side of the roof mounting plate 3 near the windshield. The water channel is arranged along the width of the vehicle body, specifically extending from one end of the roof mounting plate 3, or the windshield, to the other end; and the water guide notch 401 is connected to the water channel. With this arrangement, rainwater flowing out of the mounting space can enter the water channel and be guided by the water channel to both sides of the windshield, thus avoiding flowing onto the windshield and obstructing the view of the occupants.

[0038] Specifically, the water channel can be formed on the roof mounting plate 3, or it can be formed through the strip interval between the windshield and the roof mounting plate 3.

[0039] like Figure 1 As shown, to further enhance the rapid drainage of rainwater, a portion of the roof mounting plate 3 forming the installation space is inclined, and the height of this portion gradually decreases from the vehicle body as it approaches the windshield. Thus, the area of ​​the roof mounting plate 3 below the radar 2 is inclined downwards, essentially a small ramp. When rainwater enters the outer cover 1 and falls onto the roof mounting plate 3, it quickly flows to the drainage notch 401 and is drained, effectively preventing water accumulation on the roof mounting plate 3 from adversely affecting the radar 2.

[0040] Typically, the roof mounting plate 3 is provided with a mounting groove 301 that is recessed into the passenger compartment. The mounting groove 301 accommodates the radar 2 to prevent the radar 2 from protruding too much from the roof. The bottom wall of the mounting groove 301 forms the aforementioned inclined local area, or in other words, the bottom wall of the mounting groove 301 is gradually inclined downward along the direction close to the windshield.

[0041] Preferably, the inclination angle of the local area, or the bottom wall of the mounting groove 301, is θ, where 10° ≥ θ ≥ 5°, for example, 5°, 6°, 7°, 8°, 9°, 10°, etc. This allows water to flow quickly and obliquely downwards to the water guide gap 401 for discharge, while also preventing the inclination angle from being too large and affecting the roof shape or the height of the vehicle body. Of course, the inclination angle θ can also be other values.

[0042] Regarding the connection between radar 2 and outer cover plate 1, such as Figure 2 and Figure 3As shown, the connecting structure includes protrusions 11 disposed on the inner side of the outer cover plate 1, with the protrusions 11 distributed at least on both sides of the viewing window 101; thus, a space for accommodating the radar 2 is formed between the protrusions 11. Connecting plates 21 are disposed on both sides of the radar 2, and the connecting plates 21 are connected to the protrusions 11. Both the connecting plates 21 and the protrusions 11 are provided with connecting holes, and the two are fastened together by bolts passing through the connecting holes, thereby fixing the radar 2 to the outer cover plate 1. At the same time, the placement of the protrusions 11 not only facilitates connection with the connecting plates 21 on the radar 2 and prevents the bolts from protruding from the outer cover plate 1, but also creates a space for accommodating the radar 2 between the protrusions 11 on both sides of the viewing window 101, providing a certain degree of enclosure, fixation, and protection for the radar 2.

[0043] Specifically, the protrusions 11 and the connecting plates 21 are set one-to-one, and there can be two or three sets. For example, as shown in the attached figure, the radar 2 has two protrusions 11 and connecting plates 21 on one side and one protrusion 11 and connecting plate 21 on the other side. The three points are fixed, which provides high stability.

[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the outer cover plate 1 is also provided with a positioning and engaging structure that is spaced apart from the viewing window 101. The positioning and engaging structure is used to hold one end of the radar 2 opposite to the viewing window 101. Thus, when the radar 2 is fixed to the outer cover plate 1, the scanning end of the radar 2 can be inserted into the viewing window 101 first, and then the other end of the radar 2 opposite to the viewing window 101 can be pressed down and held in place by the positioning and engaging structure, thereby achieving positioning and pre-tightening of the radar 2, initially fixing the radar 2, and also aligning the connecting plate 21 and the protrusion 11 of the radar 2, for example, aligning the connecting block on the connecting plate 21 and the connecting hole on the protrusion 11, so as to facilitate the insertion of bolts for fastening.

[0045] For example, such as Figure 5 As shown, the positioning and engaging structure includes a positioning post 12 disposed on the outer cover plate 1. The positioning post 12 has a first inclined surface 121 and a second inclined surface 122 on the side facing the viewing window 101. The first inclined surface 121 and the second inclined surface 122 are arranged sequentially along the height direction. The inclination angle of the first inclined surface 121 is greater than that of the second inclined surface 122. The first inclined surface 121 is used for the end of the radar 2 to slide into the second inclined surface 122, and the second inclined surface 122 is used to abut against the end of the radar 2. Thus, when the scanning end of the front of the radar 2 is aligned with the viewing window 101 and inserted into the viewing window 101, the rear of the radar 2 is pressed down, and the rear end of the radar 2 slides along the first inclined surface 121 into the second inclined surface 122 and is abutted by the second inclined surface 122. The positioning post 12 locks the radar 2 onto the outer cover plate 1. In this way, the radar 2 can be pre-fixed, which is convenient for subsequent fixing operations. At the same time, it is also convenient to align the connecting plate 21 and the protrusion 11 and avoid installation misalignment.

[0046] like Figure 3 As shown, along the spacing direction of the protrusions 11, which is also the width direction of the vehicle body, at least two positioning posts 12 can be provided at intervals to enhance the stability and fixation of the radar 2.

[0047] Of course, in other embodiments, the positioning and engaging structure may also have a buckle on the positioning post 12 and a corresponding slot on the radar 2, or other structures that can hold the radar 2 in place, which will not be described in detail here.
