[0035] As described in the background technology, there is a problem of interference and misalignment between the existing automotive radome and radar. The inventors have found that the reason for this problem is that the current radar is usually installed on a sheet metal bracket at the front anti-collision beam of the car and matches the radome at the lower grille of the bumper. Because the bumper will deform and sink for a long time, the radome and radar will have interference and misalignment problems.

[0036] In view of the above technical problems, the embodiment of the present application provides a radar mounting bracket and a car, wherein the radar is mounted on the radar mounting bracket, and further mounted on the front grille of the car through the radar mounting bracket, that is, the radar is integrated into the front grille through the radar mounting bracket, and then integrated with the bumper. In this way, the radar in the embodiment of the present application is integrated into the front bumper and is not affected by the sinking of the bumper, thereby avoiding the interference and misalignment problem between the radar cover and the radar, and improving the reliability of the radar.

[0037] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0038] To facilitate the description of the embodiments of the present application, the coordinate system in the accompanying drawings is explained. The X-axis direction in the accompanying drawings is the first direction, which is the installation direction of the radar mounting bracket and is also the front and rear direction of the car. The Y-axis direction is the width direction of the radar mounting bracket, and the Z-axis direction is the height direction of the radar mounting bracket.

[0039] like Figure 1 and Figure 2 As shown, the automobile provided in the embodiment of the present application includes a radar 20, a front grille 30, a radar mounting bracket 10, and a radar cover 40; wherein the radar 20 may be a millimeter wave radar, and the radar 20 cooperates with the radar cover 40 to realize functions such as automatic braking and automatic following, and is one of the indispensable components for intelligent driving.

[0040] The radar 20 and the radar cover 40 are usually arranged at the front end of the car. For example, the radar cover 40 is arranged on the front grille 30, for example, the radar cover 40 is integrated with the front grille 30, and the front grille 30 is integrated with the front bumper of the car, that is, the radar cover 40 and the front bumper are an integrated structure.

[0041] Along the first direction, the radar 20 is detachably mounted on the radar mounting bracket 10 and further mounted on the front grille 30 through the radar mounting bracket 10 . The radar 20 is located between the radar cover 40 and the radar mounting bracket 10 , and the radar 20 is opposite to the radar cover 40 .

[0042] like Figure 3 As shown, the radar mounting bracket 10 provided in the embodiment of the present application is used to mount the radar 20 on the front grille 30 of the car. The radar mounting bracket 10 includes a body 11, a positioning structure and a clamping structure, wherein the body 11 is provided with an installation cavity, and part of the radar 20 is installed in the installation cavity, wherein the contour shape of the installation cavity is consistent with the contour shape of the radar 20. Along a first direction, the body 11 includes a first surface and a second surface opposite to each other along the installation direction of the radar 20, and the installation cavity penetrates the first surface and the second surface respectively.

[0043] The radar 20 can be inserted into the installation cavity from the side where the first surface is located. The above-mentioned positioning structure and the card-connecting structure are respectively arranged on the first surface of the main body 11, and the positioning structure and the card-connecting structure are arranged around the installation cavity. When the radar 20 is installed on the radar mounting bracket 10, the positioning structure is used to position the radar 20, and the card-connecting structure is used to limit the radar 20 to prevent the radar 20 from escaping from the radar mounting bracket 10.

[0044] Furthermore, if Figure 4 As shown, the positioning structure in the embodiment of the present application includes a positioning pin 12, which is arranged close to the installation cavity. The edge of the radar 20 is provided with a positioning hole that cooperates with the positioning pin 12, and the radar 20 and the radar mounting bracket 10 are positioned by the positioning pin 12 and the positioning hole.

[0045] The clamping structure includes a clamping portion 13, and the clamping portion 13 and the positioning pin 12 are arranged at intervals along the circumference of the installation cavity. The clamping portion 13 is configured to clamp to a surface of the radar 20 when the radar 20 is installed in the installation cavity, thereby limiting the position of the radar 20 along its installation direction.

[0046] It should be noted that the number of the positioning pins 12 and the clamping parts 13 can be set as needed. For example, the positioning structure may include at least one positioning pin 12, and the clamping structure may include at least one clamping part 13. The clamping part 13 and the positioning pin 12 may be arranged at intervals along the circumference of the installation cavity. For example, the body 11 is provided with a positioning pin 12 and a clamping part 13, and the positioning pin 12 and the clamping part 13 are arranged opposite to each other along the second direction or the third direction.

[0047] In the related art, the radar is installed on a sheet metal bracket at the front anti-collision beam of the car and matched with the radome at the lower grille of the bumper. The radome and the radar are installed on the anti-collision beam and the bumper respectively. Since the bumper will deform and sink permanently, interference and misalignment will occur between the radome and the radar.

[0048] However, in the embodiment of the present application, the radar 20 is integrated on the front bumper and is not affected by the sinking of the bumper, thereby avoiding interference and misalignment problems between the radar cover 40 and the radar 20 and improving the reliability of the radar 20.

[0049] On the basis of the above-mentioned embodiment, the positioning structure provided in the embodiment of the present application includes at least three positioning pins 12, and at least three positioning pins 12 are arranged at intervals around the installation cavity. For example, in one embodiment, the positioning structure includes three positioning pins 12, and the three positioning pins 12 are arranged in a triangle around the installation cavity. Exemplarily, along the third direction, one positioning pin 12 is arranged at the top end of the body 11, and the other two positioning pins 12 are arranged at intervals at the bottom end of the body 11.

[0050] Accordingly, the radar 20 is provided with three positioning holes arranged in a triangle, which will not be described in detail here. Such a configuration can improve the positioning accuracy between the radar 20 and the radar mounting bracket 10.

[0051] Further, along the first direction, one end of the positioning pin 12 is connected to the body 11, and the other end of the positioning pin 12 is configured as a tapered end, and the maximum outer diameter of the tapered end is less than or equal to the maximum outer diameter of the positioning pin 12, and the tapered end is located at the end of the positioning pin 12 away from the body 11. In this way, the tapered end can play a guiding role when the radar 20 is installed on the radar 20 mounting frame, so that the positioning hole of the radar 20 is inserted into the positioning pin 12.

[0052] The radar 20 in the embodiment of the present application includes a positioning portion 21, which may be a positioning plate provided on the body 11, and the positioning plate is located at the circumferential edge of the radar 20. Positioning holes are provided in the positioning portion 21, and each positioning portion 21 has one positioning hole, that is, the number of the positioning portions 21 is consistent with the number of the positioning holes. It should be understood that the positioning hole runs through the entire positioning portion 21 along the first direction, and when the positioning portion 21 is inserted into the positioning pin 12, the clamping portion 13 can be clamped with the surface of the positioning portion 21.

[0053] On the basis of the above embodiment, in order to improve the clamping effect between the radar 20 and the radar 20 mounting frame, the clamping structure in the embodiment of the present application is provided with two clamping parts 13 at each positioning part, the two clamping parts 13 are arranged opposite to each other along the second direction, and an accommodation space is formed between the two clamping parts 13, and the positioning part 21 can be installed in the accommodation space. When the positioning part 21 is inserted into the positioning pin 12, the two clamping parts 13 are respectively clamped with the surface of the positioning part 21 to limit the positioning part 21.

[0054] It can be understood that the clamping portion 13 provided in the embodiment of the present application is configured as an elastic clamping member, one end of which is connected to the main body 11 along the first direction, and the other end of the clamping member has a tongue, and the tongue extends along the second direction toward one side of the positioning pin 12 and can extend to the surface of the positioning portion 21.

[0055] When the positioning portion 21 needs to be inserted between the two clips, an external force can be applied to at least one of the clips to deform the clip along the second direction toward the side away from the positioning pin 12, thereby forming sufficient space between the two clips to facilitate the positioning portion 21 to be inserted into the positioning pin 12. After the insertion is completed, the clip can be released, and the tongue of the clip will be engaged with the surface of the positioning portion 21.

[0056] See also Figure 3 On the basis of the above embodiment, in order to realize the installation of the radar 20 mounting frame on the front grille 30, the body 11 in the embodiment of the present application is further provided with at least two mounting holes, and accordingly, the front grille 30 is provided with mounting sites 41 that match the mounting holes, and the mounting sites 41 can be threaded fixing holes provided on the front grille 30. Further, by inserting fasteners between the mounting holes and the mounting sites 41, the radar 20 mounting frame can be detachably mounted on the front grille 30.

[0057] For example, in the embodiment of the present application, the body 11 is rectangular, and accordingly, the mounting cavity is consistent with the shape of the body 11, that is, the mounting cavity is configured as a rectangular cavity. On this basis, the body 11 is provided with two first mounting holes 14 and two second mounting holes 15, and the four mounting holes are respectively provided at the four corners of the body 11.

[0058] like Figure 5 and Figure 6As shown, two first mounting holes 14 are arranged along the diagonal of the body 11, and the first mounting holes 14 are configured as through holes; two second mounting holes 15 are arranged along the diagonal of the body 11, and the second mounting holes 15 are configured as countersunk holes, that is, the two first mounting holes 14 are arranged along one diagonal of the body 11, and the two second mounting holes 15 are arranged along the other diagonal of the body 11. In this arrangement, the body 11 and the mounting site 41 can be pre-positioned by using the countersunk holes, and the mounting site 41 is configured with a positioning boss with a threaded fixing hole to facilitate the installation of fasteners.

[0059] Preferably, along the first direction, the mounting site 41 is arranged on the surface of the radome 40 facing the radar mounting bracket 10, and the radome 40 is integrated on the front grille 30. In this way, when the radar 20 is installed at the mounting site 41 through the radar mounting bracket 10, the radar 20 can be opposite to the radome 40, and the radar 20 is located between the radome 40 and the radar mounting bracket 10. When the bumper will have a phenomenon of permanent deformation and sinking, there is no relative displacement between the radome 40 and the radar 20, so as to avoid interference and misalignment between the two.
