DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0047] Millimeter-wave radar is usually installed on the front bumper grille of a vehicle. It is used to detect the distance to obstacles in front of the vehicle while the vehicle is driving, and provide information such as the distance, direction, and area of ​​the obstacle to ensure safe travel.

[0048] In the related art, a radar cover is integrally formed on the front bumper grille, and the radar cover is arranged on the radar to prevent rain, sand, mud, etc. from splashing onto the radar while the vehicle is driving, thereby protecting the radar. However, in the related art, the radar can only be installed on the front bumper grille on the vehicle, resulting in inflexible layout of the radar.

[0049] Based on this, an embodiment of the present invention provides a vehicle-mounted radar installation structure, a radar assembly and a vehicle. The radar installation structure includes a mounting frame and a cover, the radar is installed on the mounting frame, the cover is at least covered on the side of the radar away from the mounting frame, and the cover is connected to the mounting frame, thereby realizing a mounting frame integrated with the cover. The mounting frame is provided with a first mounting portion that is detachably connected to the front-end module of the vehicle, so that the cover and the radar can be installed together on the front-end module, such as the front anti-collision beam, the water tank frame, etc., through the mounting frame, so that the arrangement of the cover and the radar is more flexible, so that the installation position of the cover and the radar at the front end of the vehicle can be selected according to the actual working conditions, which improves the flexibility of arrangement and convenience of use.

[0050] The following is a detailed description of the vehicle-mounted radar installation structure, radar assembly and vehicle provided by the present invention through specific embodiments in conjunction with the accompanying drawings:

[0051] Reference Figures 1 to 12As shown, this embodiment provides a vehicle-mounted radar installation structure 10, which is used to install a radar 20 on a vehicle, for example, the radar 20 can be installed on a front-end module of the vehicle. The front-end module of the vehicle can specifically be a front anti-collision beam, a water tank frame, etc. The front-end module does not include the front bumper grille of the vehicle, and the front-end module is located on the side of the front bumper grille away from the front of the vehicle.

[0052] Specifically, refer to Figures 1 to 12 As shown, the vehicle-mounted radar installation structure includes a mounting frame 1 and a cover 2. The mounting frame 1 is used to install the radar 20, and a first mounting portion 11 is provided on the mounting frame 1. The mounting frame 1 is detachably mounted on a front end module located on a side of the front bumper grille of the vehicle away from the front of the vehicle through the first mounting portion 11; the cover 2 is at least covered on a side of the radar 20 away from the mounting frame 1, and the cover 2 is connected to the mounting frame 1.

[0053] The cover 2 is connected to the mounting frame 1. Since the mounting frame 1 is provided with a first mounting portion 11 connected to the front end module of the vehicle, the cover 2 can be installed on the front end module of the vehicle through the mounting frame 1. Compared with the solution in the prior art in which the cover 2 and the front grille are integrally formed, the layout of the cover 2 at the front end of the vehicle (i.e., the end where the front of the vehicle is located) is more flexible and easy to assemble. The cover 2 will not limit the arrangement of the radar 20. The cover 2 is connected to the mounting frame 1 to form an integral structure, which provides a more flexible layout basis for the radar 20, so that the layout and use of the radar 20 at the front end of the vehicle are not restricted.

[0054] By setting the cover 2 on the mounting frame 1, the cover 2 and the mounting frame 1 form an integral structure, and the mounting frame 1 integrated with the cover 2 is realized. In this way, the cover 2 is connected to the mounting frame 1, and the mounting frame 1 is connected to the front-end module of the vehicle, so that the installation of the cover 2 on the front-end module is realized, the layout is flexible, and the assembly is convenient, so that the radar 20 can be flexibly installed on a suitable front-end module according to the actual working conditions. The installation position of the radar 20 is not limited, which improves the flexibility of the layout at the front end of the vehicle.

[0055] Since the cover 2 is mounted on the mounting frame 1, the radar 20 is mounted on the mounting frame 1, and the mounting frame 1 is connected to the front-end module of the vehicle, during assembly, for example, the mounting frame 1 connected with the cover 2 and the radar 20 can be installed on the front-end module to achieve assembly, which is convenient.

[0056] It should be noted that there is no order of precedence for the connection between the radar 20 and the mounting frame 1 and the connection between the mounting frame 1 and the front-end module. During assembly, the mounting frame 1 can be connected to the front-end module first, and then the radar 20 and the cover 2 can be installed on the mounting frame 1 in sequence. Of course, at least the radar 20 can be installed on the mounting frame 1 first, and then the mounting frame 1 can be connected to the front-end module.

[0057] The front-end modules of the vehicle are all located on the side of the front bumper grille facing the rear of the vehicle (i.e., the inner side of the front bumper grille). In this way, after the radar 20 is installed on the front-end module through the vehicle-mounted radar mounting structure, the radar 20 and the vehicle-mounted radar mounting structure are both located on the inner side of the front bumper grille, which to a certain extent avoids the radar 20 and the vehicle-mounted radar mounting structure from being damaged by foreign objects outside the vehicle, and also improves the protection performance of the vehicle-mounted radar mounting structure for the radar 20, thereby extending the service life of the radar 20 and the vehicle-mounted radar mounting structure.

[0058] Moreover, the radar 20 is installed on the front-end module through the vehicle-mounted radar mounting structure. Compared with the solution in the prior art in which the radar 20 is installed on the front bumper grille, the signal emitting surface of the radar 20 and the cover 2 have more space to select a more suitable arrangement angle, so that the detection direction of the radar 20 is better, which helps to improve the detection performance of the radar assembly.

[0059] The vehicle-mounted radar installation structure provided in this embodiment is such that the radar 20 installation structure includes a mounting frame 1 and a cover 2, the radar 20 is installed on the mounting frame 1, the cover 2 is at least covered on the side of the radar 20 away from the mounting frame 1, and the cover 2 is connected to the mounting frame 1, so as to realize the mounting frame 1 integrated with the cover 2. The mounting frame 1 is provided with a first mounting portion 11, and the mounting frame 1 is connected to the front-end module of the vehicle, such as the front bumper beam, the water tank frame, etc., through the first mounting portion 11, so that the cover 2 and the radar 20 can be installed on the front-end module together through the mounting frame 1, and the arrangement of the cover 2 and the radar 20 is relatively flexible. Compared with the solution in the prior art that the radar cover is integrally formed with the front bumper grille, so that the radar can only be arranged relying on the front bumper grille, the vehicle-mounted radar installation structure provided by the present invention enables the cover 2 and the radar 20 to be connected to the front-end modules such as the front bumper beam and the water tank frame, so that the installation position of the cover 2 and the radar 20 at the front end of the vehicle can be selected according to the actual working conditions, thereby improving the flexibility of arrangement and convenience of use.

[0060] Moreover, the cover 2 and the radar 20 are installed on the front-end module through the mounting frame 1, so that the front bumper and the grille do not need to consider the arrangement of the cover 2 and the installation of the radar 20, which reduces the design and manufacturing difficulty of the front bumper and the grille, and allows the front bumper and the grille to have more styling space.

[0061] refer to Figures 2 to 4 As shown, in some embodiments, the first mounting portion 11 includes a first mounting hole, and a second mounting hole (not shown) is provided on the front-end module. The mounting frame 1 is detachably connected by fasteners penetrated through the first mounting hole and the second mounting hole. The structure is simple, and the connection is convenient and firm.

[0062] At the same time, if the mounting frame 1 or the front-end module is damaged and needs to be replaced, it is only necessary to disassemble and separate the mounting frame 1 and the front-end module, and replace the damaged one that needs to be replaced. There is no need to replace the mounting frame 1 and the front-end module as a whole, which saves costs to a certain extent.

[0063] In some implementations, the first mounting hole may be, for example, a threaded hole, and the second mounting hole may also be, for example, a threaded hole. The mounting frame 1 is threadedly connected to the front-end module by screws passing through the two threaded holes, which is easy to manufacture and has a firm connection.

[0064] refer to Figures 2 to 4 As shown, in a specific implementation, for example, a plurality of first mounting portions 11 may be provided on the mounting frame 1, and the plurality of first mounting portions 11 are arranged at circumferential intervals along the mounting frame 1, and a plurality of second mounting portions are correspondingly provided on the front-end module, and the first mounting portions 11 are connected to the second mounting portions one by one, thereby making the connection strength between the mounting frame 1 and the front-end module higher and the connection more stable.

[0065] For example, reference Figures 2 to 4 As shown, three first mounting parts 11 are provided on the mounting frame 1. Specifically, three threaded holes are provided on the mounting frame 1, so that the mounting frame 1 can be connected to the front-end module by screws respectively inserted into the three threaded holes, which is convenient for installation and disassembly and has a firm connection.

[0066] In other embodiments, the first mounting portion 11 may be, for example, a buckle, a slot is provided on the front-end module, and the mounting frame 1 is connected to the front-end module through the cooperation of the buckle and the slot.

[0067] refer to Figure 2 , Figures 4 to 7 As shown, in some embodiments, a first positioning portion 12 is provided on the mounting frame 1, and a second positioning portion (not shown) is provided on the front-end module. The first positioning portion 12 and the second positioning portion are matched and connected to position the mounting frame 1. The first positioning portion 12 and the second positioning portion are matched and connected to position the connection of the mounting frame 1 on the front-end module for easy assembly.

[0068] During specific assembly, by matching and connecting the first positioning portion 12 and the second positioning portion, the first mounting hole on the mounting frame 1 and the second mounting hole on the front-end module are coaxially arranged. In this way, the mounting frame 1 can be connected to the front-end module by threading the screws in the first mounting hole and the second mounting hole, which facilitates assembly and helps to improve assembly efficiency.

[0069] Continue to refer Figure 2 , Figures 4 to 7As shown, in some embodiments, the first positioning portion 12 includes a positioning column, and the second positioning portion includes a positioning hole (not shown) for the positioning column to extend into, which has a simple structure, is easy to manufacture, and has firm and convenient positioning.

[0070] Of course, in other embodiments, the first positioning portion 12 may be, for example, a positioning hole provided on the mounting frame 1 , and the second positioning portion may be a positioning column provided on the front-end module.

[0071] By setting a positioning column on one of the mounting frame 1 and the front-end module, and setting a positioning hole on the other of the mounting frame 1 and the front-end module, for example, referring to Figure 2 , Figures 4 to 7 As shown, a positioning column is provided on the mounting frame 1, so that during assembly, the positioning column is extended into the positioning hole, and the mounting frame 1 can be pre-hung on the front-end module, and the first mounting hole and the second mounting hole are coaxially arranged, so that the mounting frame 1 can be locked on the front-end module by threading the screws in the first mounting hole and the second mounting hole, and there is no need to manually support the mounting frame 1 for installation, which makes assembly more convenient.

[0072] In some embodiments, reference Figure 2 , Figures 4 to 7 As shown, there are at least two first positioning portions 12, at least two first positioning portions 12 are arranged at intervals along the circumference of the mounting frame 1, and at least two first positioning portions 12 are staggered along the length direction or width direction of the mounting frame 1, and there are at least two second positioning portions, and the first positioning portions 12 are connected to the second positioning portions one by one, so that the installation accuracy of the mounting frame 1 on the front-end module is higher through the cooperation of multiple first positioning portions 12 and the corresponding second positioning portions.

[0073] Furthermore, at least two first positioning portions 12 are staggered in the length direction or width direction of the mounting frame 1, so that the cooperation between the first positioning portion 12 and the second positioning portion has an anti-misassembly function for the assembly of the mounting frame 1 on the front-end module, thereby improving the assembly efficiency.

[0074] For example, reference Figure 4 and Figure 7 As shown, two positioning columns are arranged on the mounting frame 1, one of which is arranged at the top of the mounting frame 1 on the side away from the cover 2 (i.e., the side of the mounting frame 1 facing the front-end module), and the other positioning column is arranged at the bottom of the mounting frame 1 on the side away from the cover 2. The two positioning columns are staggered along the width direction of the mounting frame 1, thereby avoiding the phenomenon of the mounting frame 1 being misplaced during assembly and improving the assembly efficiency.

[0075] Of course, in other implementations, two positioning columns are provided on the mounting frame, one of which is provided near one width side of the mounting frame, and the other is provided near another width side of the mounting frame. The two positioning columns can be provided at intervals along the length direction of the mounting frame, for example.

[0076] refer to Figures 2 to 4 , Figure 6 , Figure 7 and Fig.12 As shown, in some embodiments, a first connecting portion 31 is provided on the mounting frame 1, and a second connecting portion 32 is provided on the cover 2. The mounting frame 1 is detachably connected to the cover 2 through the first connecting portion 31 and the second connecting portion 32, with a simple structure and convenient and firm connection.

[0077] At the same time, if the mounting frame 1 or the cover 2 is damaged and needs to be replaced, it is only necessary to disassemble and separate the mounting frame 1 and the cover 2, and replace the damaged one that needs to be replaced. There is no need to replace the mounting frame 1 and the cover 2 as a whole, which saves costs to a certain extent.

[0078] In some embodiments, reference Figure 3 , Figure 4 and Fig.12 As shown, there are at least two first connection parts 31, and at least two first connection parts 31 are arranged at intervals along the circumference of the mounting frame 1. There are at least two second connection parts 32, and the first connection parts 31 are connected to the second connection parts 32 one by one, so that the connection strength and connection stability between the mounting frame 1 and the cover 2 are higher.

[0079] For example, Figure 3 , Figure 4 and Fig.12 As shown, four first connection parts 31 are provided on the mounting frame 1, and the four first connection parts 31 are arranged at intervals along the circumference of the mounting frame 1. Four second connection parts 32 are provided on the cover 2, and the four first connection parts 31 are matched and connected with the corresponding second connection parts 32 respectively.

[0080] refer to Figure 3 , Figure 4 , Figure 7 , Fig.11 and Fig.12 As shown, in some embodiments, the first connecting portion 31 includes a first slot, and the second connecting portion 32 includes a first claw extending into the first slot, which has a simple structure and is easy to manufacture and assemble.

[0081] In other embodiments, the first connection portion 31 may be, for example, a first claw disposed on the mounting frame 1 , and the second connection portion 32 may be a first slot disposed on the cover 2 .

[0082] refer to Figure 2 , Figure 6 , Figure 7 and Fig.11 As shown, in some embodiments, a second claw 33 is provided on the side of the mounting frame 1 facing away from the cover 2, and the second claw 33 is located on one side of the first slot, referring to Fig.12 As shown, the first claw is provided with a second slot 34, and the second claw 33 extends into the second slot 34 when the first claw is inserted into the first slot. That is to say, when the first claw on the cover 2 is inserted into the first slot on the mounting frame 1, the second claw 33 on the mounting frame 1 extends into the second slot 34 on the first claw, thereby locking the cover 2 on the mounting frame 1, thereby improving the connection strength and connection stability between the cover 2 and the mounting frame 1, so that the cover 2 can be stably covered on the radar 20 to protect the radar 20.

[0083] In some embodiments, an anti-mis-installation structure is provided between the mounting frame 1 and the cover 2, and the anti-mis-installation structure is used to prevent the cover 2 from being mis-installed on the mounting frame 1, thereby improving the assembly efficiency.

[0084] For specific implementation, refer to Figure 3 , Figure 4 , Figure 8 and Fig.12 As shown, the anti-misinstallation structure includes an anti-misinstallation slot 41 provided on the mounting frame 1 and an anti-misinstallation protrusion 42 provided on the cover 2. The anti-misinstallation protrusion 42 extends into the anti-misinstallation slot 41 to prevent the cover 2 from being installed incorrectly.

[0085] By providing an anti-error slot 41 on the mounting frame 1 and an anti-error insertion protrusion 42 on the cover 2, during assembly, the assembly of the cover 2 on the mounting frame 1 has an anti-error assembly function through the cooperation of the anti-error insertion protrusion 42 and the anti-error slot 41, which helps to improve assembly efficiency.

[0086] During assembly, when the anti-error insertion protrusion 42 and the anti-error insertion slot 41 are matched and connected, the first connection portion 31 and the second connection portion 32 are matched and connected, thereby preventing the cover 2 from being assembled incorrectly and improving the assembly efficiency.

[0087] Illustratively, by the mating connection between the anti-error insertion protrusion 42 and the anti-error slot 41, the first claw and the first slot can be mated together. The mating of the anti-error insertion protrusion 42 and the anti-error slot 41 has a guiding effect on the mating of the first claw and the first slot, making it easy to connect the cover 2 to the mounting frame 1, and the assembly efficiency is high.

[0088] In other embodiments, for example, the mounting frame 1 may be provided with an anti-error insertion protrusion 42 , and the cover 2 may be provided with an anti-error insertion slot 41 .

[0089] refer to Figure 3 , Figure 5 and Figure 8As shown, in some embodiments, a housing cavity 5 is provided on the mounting frame 1, the radar 20 is installed in the housing cavity 5, and a side of the housing cavity 5 facing the cover 2 has an avoidance window 51 for exposing the signal emitting surface of the radar 20.

[0090] By providing the accommodating cavity 5 on the mounting frame 1, the radar 20 is installed in the accommodating cavity 5, thereby improving the connection strength and connection stability of the radar 20 on the mounting frame 1. At the same time, the accommodating cavity 5 also has a certain protective effect on the radar 20, which helps to extend the service life of the radar 20.

[0091] refer to Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, a mounting opening 52 is provided on the mounting frame 1. The mounting opening 52 is located on one side of the accommodating cavity 5 and is communicated with the accommodating cavity 5. The mounting opening 52 is used for allowing the radar 20 to enter the accommodating cavity 5, or for allowing the radar 20 to be moved out of the accommodating cavity 5, so that the radar 20 can be detachably connected to the accommodating cavity 5 through the mounting opening 52, which facilitates the assembly of the radar 20.

[0092] The avoidance window 51 is located on the side of the mounting frame 1 facing the front of the vehicle, that is, the avoidance window 51 is located on the front side of the mounting frame 1 .

[0093] Exemplarily, the installation opening 52 can be located on one side of the accommodating cavity 5 along the width direction of the vehicle. In this way, the radar 20 is placed at the installation opening 52 and moved toward the direction close to the accommodating cavity 5. The radar 20 can be assembled in the accommodating cavity 5 without interfering with the avoidance window 51, thereby not affecting the signal emitting surface of the radar 20 to emit detection signals, and is more practical.

[0094] By making the radar 20 detachably connected in the accommodating cavity 5, if one of the radar 20 and the mounting bracket 1 is damaged and needs to be replaced, it is only necessary to disassemble and separate the radar 20 and the mounting bracket 1, and replace the damaged one that needs to be replaced. There is no need to replace the radar 20 and the mounting bracket 1 as a whole, which saves costs to a certain extent.

[0095] Of course, in other embodiments, the radar 20 and the cavity wall of the accommodating cavity 5 can be bonded together, for example.

[0096] refer to Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, a first limiting portion 61 is provided at the edge of the avoidance window 51, and the first limiting portion 61 has an overlapping portion with the avoidance window 51. A first elastic limiting portion 62 is provided on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51. The first elastic limiting portion 62 and the first limiting portion 61 are both used to abut against the radar 20 to fix the radar 20 in the accommodating cavity 5.

[0097] Since the avoidance window 51 is arranged toward the cover 2 and is used to expose the signal transmission surface of the radar 20, the avoidance window 51 is located on the side of the accommodating chamber 5 facing the front of the vehicle. Since the first elastic limiting portion 62 is arranged on the cavity wall of the accommodating chamber 5 opposite to the avoidance window 51, the first elastic limiting portion 62 is located on the side of the accommodating chamber 5 facing the rear of the vehicle. Therefore, the avoidance window 51 and the first elastic limiting portion 62 are arranged at intervals along the length direction of the vehicle, and are arranged on two opposite cavity walls of the accommodating chamber 5 along the length direction of the vehicle.

[0098] By providing a first limiting portion 61 at the edge of the avoidance window 51, and making the first limiting portion 61 overlap with the avoidance window 51, that is, the first limiting portion 61 extends in the direction close to the avoidance window 51, and at least a part of the first limiting portion 61 is located in the area where the avoidance window 51 is located, by providing a first elastic limiting portion 62 on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51, and the first elastic limiting portion 62 and the first limiting portion 61 are both in contact with the radar 20, specifically, the first elastic limiting portion 62 is in contact with the side of the radar 20 facing away from the cover 2, and the first limiting portion 61 is in contact with the side of the radar 20 facing the cover 2, so that the first elastic limiting portion 62 and the first limiting portion 61 cooperate with each other to limit the radar 20 in the length direction of the vehicle, and stably fix the radar 20 in the accommodating cavity 5.

[0099] Among them, the first elastic limiting portion 62 can move in the direction close to or away from the accommodating cavity 5, that is, the first elastic limiting portion 62 can undergo elastic deformation in the length direction of the vehicle, which not only facilitates the radar 20 to enter the accommodating cavity 5 from the installation opening 52, or move out of the accommodating cavity 5, making the radar 20 easy to install and disassemble, but also can when the radar 20 is in the accommodating cavity 5, it can press against the side of the radar 20 away from the cover 2, thereby cooperating with the first limiting portion 61 to stably fix the radar 20 in the accommodating cavity 5.

[0100] refer to Figure 3 , Figure 5 , Figure 6 and Fig. 9 As shown, in some embodiments, the first limiting portion 61 includes a limiting protrusion, which has a simple structure and is easy to manufacture.

[0101] In some embodiments, reference Figure 6 and Fig. 9As shown, the first limiting portion 61 has a first guiding slope 611 on one side facing the mounting opening 52. The first guiding slope 611 is inclined in the direction from the mounting opening 52 to the first limiting portion 61 toward the direction close to the accommodating cavity 5. In this way, when the radar 20 is extended into the accommodating cavity 5 for assembly, the first guiding slope 611 has a guiding effect on the extension of the radar 20, thereby facilitating the assembly of the radar 20.

[0102] In some embodiments, reference Figure 6 and Fig. 9 As shown, the first limiting portion 61 has a second guiding slope 612 on the side away from the mounting opening 52. The second guiding slope 612 is inclined in the direction from the mounting opening 52 to the first limiting portion 61 and is arranged away from the accommodating cavity 5. In this way, when the radar 20 is extended out of the accommodating cavity 5 for disassembly, the second guiding slope 612 guides the extension of the radar 20, thereby facilitating the disassembly of the radar 20.

[0103] In some embodiments, reference Fig. 9 As shown, the side of the first limiting portion 61 facing the accommodating cavity 5 may have, for example, an abutting plane 613 for abutting against the radar 20 , which has a better fixing and limiting effect on the radar 20 and contributes to the connection stability of the radar 20 .

[0104] In a specific implementation, the abutting plane 613 can be located between the first guiding inclined plane 611 and the second guiding inclined plane 612. There is an arc transition between the abutting plane 613 and the first guiding inclined plane 611, and there is an arc transition between the abutting plane 613 and the second guiding inclined plane 612, so that scratches on the radar 20 are avoided during installation and disassembly, and the use safety is higher.

[0105] In some implementations, a side of the abutting plane 613 facing the accommodating cavity 5 may be provided with a flexible anti-skid pad, for example, to further prevent the radar 20 from being scratched.

[0106] In some embodiments, there are at least two first limiting portions 61, and at least two first limiting portions 61 are arranged at intervals along the circumference of the avoidance window 51. At least two first limiting portions 61 are arranged at least on two opposite sides of the avoidance window 51. That is to say, multiple first limiting portions 61 are arranged at intervals at the edge of the avoidance window 51. In specific implementation, multiple first limiting portions 61 are arranged at least on two opposite sides of the avoidance window 51, which has a better limiting and fixing effect on the radar 20, so that the radar 20 can be more stably fixed on the mounting frame 1.

[0107] For example, reference Figure 3 and Figure 5As shown, four first limiting portions 61, such as limiting protrusions, are provided at the edge of the avoidance window 51. The four limiting protrusions are provided on opposite sides of the avoidance window 51 along the width direction of the mounting frame 1. Figure 3 and Figure 5 As shown, two limiting protrusions are arranged at the top edge of the avoidance window 51 , and two limiting protrusions are arranged at the bottom edge of the avoidance window 51 .

[0108] In some embodiments, at least two first elastic limiting portions 62 are spaced apart on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51. For example, referring to Figures 2 to 4 as well as Figures 6 to 8 As shown, two first elastic limiting portions 62 are spaced apart on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51 , so as to better limit and fix the radar 20 .

[0109] In some embodiments, a avoidance hole 53 is provided on the cavity wall of the accommodating cavity 5 opposite to the first limiting portion 61, and a first elastic limiting portion 62 is provided on the cavity wall of the avoidance hole 53 on the side facing the installation port 52. The first elastic limiting portion 62 is spaced apart from other hole walls of the avoidance hole 53 and can move toward or away from the accommodating cavity 5 to abut against the radar 20. That is to say, the edge of the first elastic limiting portion 62 on the side facing the installation port 52 is connected to the hole wall of the avoidance hole 53, and the other edges of the first elastic limiting portion 62 are spaced apart from other hole walls of the avoidance hole 53. The first elastic limiting portion 62 can move back and forth toward or away from the accommodating cavity 5, thereby abutting against the radar 20 to achieve fixed limiting of the radar 20.

[0110] By setting an avoidance hole 53 on the cavity wall of the accommodating cavity 5 opposite to the first limiting portion 61, and setting the first elastic limiting portion 62 in the avoidance hole 53, a larger deformation space is provided for the first elastic limiting portion 62, so that the elastic supporting force of the first elastic limiting portion 62 on the radar 20 is relatively strong.

[0111] Of course, in other implementations, for example, the first elastic limiting portion 62 may be directly connected to the cavity wall of the accommodating cavity 5 opposite to the first limiting portion 61 , and the first elastic limiting portion 62 has a cantilevered wall portion spaced apart from the cavity wall of the accommodating cavity 5 .

[0112] In a specific implementation, the first elastic limiting portion 62 can be, for example, a spring sheet, which has a simple structure and is easy to manufacture.

[0113] refer to Figures 2 to 6 as well as Figures 8 to 10As shown, in some embodiments, a second elastic limiting portion 7 is provided on the side of the installation port 52 facing the cover 2, and the second elastic limiting portion 7 can move in a direction close to or away from the installation port 52. The second elastic limiting portion 7 is used to abut against the radar 20 when the radar 20 abuts against the cavity wall of the accommodating cavity 5 opposite to the installation port 52.

[0114] In a specific implementation, one side of the second elastic limiting portion 7 facing the avoidance window 51 extends toward the direction close to the avoidance window 51, and has an overlapping portion with the avoidance window 51. The second elastic limiting portion 7 can move toward a direction close to or away from the installation opening 52, that is, the second elastic limiting portion 7 can move toward a direction close to or away from the cover 2, so as to abut against the radar 20 when the radar 20 is installed in the accommodating cavity 5.

[0115] Specifically, when the radar 20 is moved from the installation opening 52 toward the accommodating cavity 5 for assembly, the second elastic limiting portion 7 moves in a direction away from the installation opening 52, so that the radar 20 can be extended into the accommodating cavity 5, and the assembly is convenient; and when the radar 20 enters the accommodating cavity 5 and abuts against the cavity wall of the accommodating cavity 5 opposite to the installation opening 52, the second elastic limiting portion 7 moves in a direction close to the installation opening 52 to abut against the side of the radar 20 facing the installation opening 52, thereby limiting and fixing the radar in the accommodating cavity 5.

[0116] The second elastic limiting portion 7 cooperates with the cavity wall of the accommodating cavity 5 opposite to the installation opening 52 to limit the radar in a second direction perpendicular to the length direction of the vehicle, thereby more stably fixing the radar 20 in the accommodating cavity 5 and improving the installation stability of the radar 20.

[0117] Exemplarily, the installation opening 52 is opened on one side of the accommodating cavity 5 along the width direction of the vehicle, so that the second elastic limiting portion 7 cooperates with the cavity wall of the accommodating cavity 5 on the other side along the width direction of the vehicle to limit and fix the radar 20 in the width direction of the vehicle.

[0118] In some implementations, the edge of the avoidance window 51 facing the installation opening 52 has a notch, which is recessed in the direction away from the avoidance window 51, with the notch opening facing the avoidance window 51. The second elastic limiting portion 7 is disposed in the notch, and the second elastic limiting portion 7 is connected to the bottom of the notch and is spaced apart from the wall of the notch. In this way, the elastic effect of the second elastic limiting portion 7 is better, and the resistance to the radar 20 is stronger.

[0119] refer to Fig.10 and Fig.11As shown, in some embodiments, a first abutting surface 71 and a second abutting surface 72 are provided on the side of the second elastic limiting portion 7 facing the avoidance window 51, and the second abutting surface 72 is located on the side of the first abutting surface 71 away from the mounting port 52, and extends toward the avoidance window 51. The first abutting surface 71 is used to abut against the side of the radar 20 facing the mounting port 52, and the second abutting surface 72 is used to abut against the side of the radar 20 facing the cover 2, so that the first abutting surface 71 and the second abutting surface 72 form a step structure, which can abut against both sides of the radar 20 at the same time, thereby limiting and fixing the radar 20 in two directions, further improving the structural stability of the radar 20 in the accommodating cavity 5.

[0120] refer to Figure 3 and Figure 8 As shown, in some embodiments, at least one first support member 81 is provided on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51, and the first support member 81 extends along the entry direction or the removal direction of the radar 20, so that when the radar 20 is fixed in the accommodating cavity 5, the radar 20 abuts against the first support member 81, so that the first support member 81 can not only absorb and compensate for the tolerance between the radar 20 and the accommodating cavity 5, which is convenient for assembly, but also reduces the friction between the accommodating cavity 5 and the radar 20 to a certain extent, thereby avoiding the occurrence of wear and tear of the radar 20 and improving the safety of use.

[0121] At the same time, since the first support member 81 extends along the entry direction or the removal direction of the radar 20 , the first support member 81 also has a certain guiding effect on the installation and disassembly of the radar 20 .

[0122] Exemplarily, the first support member 81 includes a first strip-shaped support rib. Specifically, the first support rib is extended in a direction from the installation opening 52 to a cavity wall of the accommodating cavity 5 opposite to the installation opening 52 .

[0123] In a specific implementation, when a plurality of first support members 81 are disposed on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51 , the plurality of first support members 81 are parallel to each other and spaced apart.

[0124] refer to Figure 3 and Figure 8 As shown, in some embodiments, at least one second support member 82 is provided on the cavity wall of the accommodating cavity 5 opposite to the installation port 52, and the second support member 82 extends in the direction from the avoidance window 51 to the cover 2, so that when the radar 20 is fixed in the accommodating cavity 5, the radar 20 abuts against the second support member 82, so that the second support member 82 can not only absorb and compensate for the tolerance between the radar 20 and the accommodating cavity 5, which is convenient for assembly, but also reduces the friction between the accommodating cavity 5 and the radar 20 to a certain extent, thereby avoiding the occurrence of wear and tear of the radar 20 and improving the safety of use.

[0125] In some implementations, the second support member 82 includes a strip-shaped second support rib, and the second support rib extends in a direction from the avoidance window 51 to the cover 2 .

[0126] In a specific implementation, when a plurality of first support members 81 are disposed on the cavity wall of the accommodating cavity 5 opposite to the avoidance window 51 , the plurality of first support members 81 are parallel to each other and spaced apart.

[0127] This embodiment also provides a radar assembly, which includes a radar and a vehicle-mounted radar mounting structure.

[0128] Among them, the radar is installed on the vehicle-mounted radar mounting structure, and the vehicle-mounted radar mounting structure is installed on the front-end module of the vehicle, so that the radar can be selectively installed at a suitable installation position at the front end of the vehicle through the vehicle-mounted radar mounting structure, such as the front anti-collision beam, water tank frame, etc., which improves the flexibility of radar layout and convenience of use.

[0129] At the same time, the front-end modules are located on the side of the front bumper grille facing the rear of the vehicle (i.e., the inner side of the front bumper grille). In this way, after the radar assembly is installed on the front-end module, the radar assembly is also located on the inner side of the front bumper grille, which to a certain extent avoids the radar assembly from being damaged by foreign objects outside the vehicle, and helps to extend the service life of the radar assembly.

[0130] Moreover, when the radar assembly is installed on the front-end module, compared with the solution in the prior art in which the radar assembly is installed on the front bumper grille, the radar's signal emitting surface and cover have more space to select a more appropriate arrangement angle, thereby making the radar's detection direction better and helping to improve the detection performance of the radar assembly.

[0131] The vehicle-mounted radar installation structure in this embodiment has the same structure and implementation principle as the vehicle-mounted radar installation structure provided in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here, and please refer to the description of the above embodiment for details.

[0132] This embodiment also provides a vehicle, which includes a front-end module and a vehicle-mounted radar installation structure, or includes a radar assembly.

[0133] Among them, the front-end module is located on the side of the front bumper grille of the vehicle away from the front of the vehicle. A second mounting portion is provided on the front-end module. The vehicle-mounted radar mounting structure is detachably connected to the front-end module through the first mounting portion 11 and the second mounting portion. In this way, the installation position of the cover and the radar at the front end of the vehicle can be selected according to the actual working conditions, thereby improving the flexibility of the radar layout.

[0134] Moreover, the cover and the radar are installed on the front-end module through the mounting frame, so the front bumper grille does not need to consider the layout of the cover and the installation of the radar, which reduces the design and production difficulty of the front bumper grille and allows the front bumper and grille to have more styling space.

[0135] At the same time, since the cover is detachably mounted on the front-end module through the mounting frame, when one of the cover, the mounting frame and the front-end module is damaged, the mounting frame and the front-end module can be disassembled and separated for replacement and repair. The replacement and repair is relatively convenient and saves the replacement cost to a certain extent.

[0136] The vehicle-mounted radar installation structure in this embodiment has the same structure and implementation principle as the vehicle-mounted radar installation structure provided in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here, and please refer to the description of the above embodiment for details.

[0137] The radar assembly in this embodiment has the same structure and implementation principle as the radar assembly provided in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiment.
