Detailed implementation manners

[0027] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and the description are regarded as being exemplary in nature rather than restrictive.

[0028] Figure 1 The structural schematic diagram of a radar mounting bracket according to an embodiment of the present disclosure is shown. As Figure 1 shown, the radar mounting bracket 100 includes:

[0029] The first mounting seat 10 is used for connecting with the front anti-collision beam of the vehicle.

[0030] The second mounting seat 20 is used for connecting with the radar.

[0031] The connecting arm 30 is arranged between the first mounting seat 10 and the second mounting seat 20. The connecting arm 30 has a preset length in the vertical direction, so that after the radar mounting bracket is assembled with the radar and the front anti-collision beam, the radar is suspended below the front anti-collision beam.

[0032] In the embodiment of the present disclosure, with Figure 1 as a reference, it is defined that Figure 1 in the Z-axis direction is the up-and-down direction of the radar mounting bracket, the X-axis direction is the front-and-back direction, and at the same time, the X-axis direction is also the front-and-back direction of the vehicle, and the Y-axis direction is the left-and-right direction. Among them, the first mounting seat 10 is located in front of the second mounting seat 20.

[0033] The first mounting seat 10 forms a mounting plane for connecting with the front anti-collision beam of the vehicle, and the second mounting seat 20 forms a mounting plane for connecting with the radar. The first mounting seat 10 and the second mounting seat 20 may have bolt holes 39 for connection, and the positions and numbers of the bolt holes 39 are not limited. The second mounting seat 20 may be provided with mounting holes 21 for connecting with the outer cover of the radar.

[0034] In one example, as Figure 2 、 3As shown, the mounting plane formed by the first mounting seat 10 is a vertical plane for connecting with the surface of the front bumper beam 200 facing the front of the vehicle. A bolt hole 39 is provided at each of the four corners of the first mounting seat 10. The mounting plane formed by the second mounting seat 20 is a horizontal plane for connecting with the base of a radar (not shown), so that the radar is hung upside down under the second mounting seat 20. A bolt hole 39 is also provided at each of the four corners of the second mounting seat 20.

[0035] The first end of the connecting arm 30 is connected to the first mounting seat 10, and the second end is connected to the second mounting seat 20. The connecting arm 30 has a preset length in the vertical direction, so that the ground clearance of the second mounting seat 20 is less than the ground clearance of the bottom edge of the first mounting seat 10, that is, the ground clearance of the second mounting seat 20 is not greater than the ground clearance of the bottom edge of the front bumper beam. And by adjusting the preset length, a certain height difference can be formed between the second mounting seat 20 and the front bumper beam. Thus, when the vehicle collides, since the radar and the front bumper beam are not at the same height, it can effectively prevent the radar from colliding with or being squeezed by the front bumper beam 200 with a very high structural strength. And if the radar mounting bracket breaks due to impact, the radar will naturally fall downward and will not collide with the front bumper beam 200 during the falling process.

[0036] In one example, the connecting arm 30 has a preset length in both the vertical direction and the front-back direction, so that the radar is installed in front of and below the front bumper beam 200. Installing the radar closer to the front of the vehicle can increase the detection angle of the radar.

[0037] According to the solution of the embodiment of the present disclosure, by staggering the radar and the front bumper beam in height, the radar can be effectively protected when the vehicle collides, thereby reducing the maintenance cost.

[0038] In one implementation, the connecting arm 30 has a structural weakening part.

[0039] In the embodiment of the present disclosure, a structural weakening part is provided on the connecting arm 30. The structural weakening part can be understood as a self-collapse structure or a force-relieving structure, which is used to cause the bracket to self-collapse from the structural weakening part, that is, break or bend from the structural weakening part once the impact force on the radar exceeds a threshold value. After breaking, the radar is separated from the vehicle, avoiding the radar from bearing a large impact force. At the same time, the radar can collapse to the rear of the front bumper beam, which is beneficial to reducing the damage to the radar itself. For example, when the impact force reaches or exceeds 80% of the radar's tolerable capacity, the structural weakening part of the bracket actively breaks, causing the radar to fall to the lower guard plate of the front bumper.

[0040] The impact force that the radar can withstand is affected by various factors such as the outer shell of different models of radars, the mechanical properties of the materials used in the internal components, the weight, and the wall thickness. It can be calculated or obtained through experiments using existing related technologies, and the embodiment of the present disclosure does not limit this here.

[0041] According to the solution of the embodiment of the present disclosure, by providing a structural weakening portion, the radar mounting bracket can self-collapse when being violently impacted, break or bend from the structural weakening portion, and avoid further damage to the radar.

[0042] In one embodiment, at least one long hole 33 is provided on the connecting arm 30, and the long hole 33 forms a structural weakening portion.

[0043] In the embodiment of the present disclosure, the long hole 33 extends in a first direction on the connecting arm 30. The first direction may be the length direction of the connecting arm 30 or the direction of the line connecting the center points of the first mounting seat 10 and the second mounting seat 20. The connecting arm 30 is between the first mounting seat 10 and the second mounting seat 20. When the radar is impacted, stress is concentrated on the connecting arm 30. By providing the long hole 33 penetrating the body of the connecting arm 30 on the connecting arm 30, the cross-sectional area of the connecting arm 30 is reduced, achieving the effect of reducing the structural strength of the connecting arm 30.

[0044] In one embodiment, the connecting arm 30 includes a pair of side wall portions 31 and a transverse portion 32 between the two side wall portions 31, and at least one long hole 33 is provided on the transverse portion 32 and / or the side wall portions 31.

[0045] In the embodiment of the present disclosure, when not impacted, the connecting arm 30 needs to have a certain strength to ensure the stability of the radar and avoid large - degree shaking or bending of the radar mounting bracket during normal driving. For this, as Figure 1 shown, the connecting arm 30 includes a pair of side wall portions 31. The side wall portions 31 have a thickness in the vertical direction to form side plates, so as to ensure that the connecting arm 30 can stably hang the radar below.

[0046] In one example, the connecting arm 30 may be a hollow square tube. The square tube includes two side wall portions 31 and two transverse portions 32. At least one long hole 33 may be provided on each side wall portion 31. Alternatively, at least one long hole 33 may be provided on each transverse portion 32. Alternatively, at least one long hole 33 is provided on each side wall portion 31 and each transverse portion 32.

[0047] According to the solution of the embodiment of the present disclosure, the side wall portions effectively support the second mounting seat, and the transverse portion is structurally weakened, so that the connecting arm structure is stable and can self-collapse and break when being impacted.

[0048] In one embodiment, a groove 34 for reducing the thickness of the connecting arm 30 in at least one direction is provided on the connecting arm 30.

[0049] In the embodiment of the present disclosure, as Figure 4As shown, the structural weakening part is provided in the form of a groove 34, and the groove 34 is provided on the surface of the connecting arm 30. Usually, the orientation of the groove 34 matches the force direction during impact or the bending direction of the connecting arm 30. Since the groove 34 is provided on the surface of the connecting arm 30, the connecting arm 30 can be solid. For example, the connecting arm 30 can be at least one cylindrical or square column. The groove 34 can be provided on the upper surface or the lower surface of the connecting arm 30, or can be provided in a circle along the circumference of the connecting arm 30, so as to reduce the cross-sectional area of the connecting arm 30 and achieve the effect of reducing the structural strength of the connecting arm 30.

[0050] In one embodiment, the connecting arm 30 includes a pair of side wall portions 31 extending in the vertical direction. Grooves 34 are symmetrically provided on the pair of side wall portions 31. The vertical length of the side wall portion 31 where the groove 34 is located is less than the vertical lengths of the side wall portions 31 on both sides of the groove 34, and the groove 34 forms a structural weakening part.

[0051] In the embodiment of the present disclosure, as Figure 1 shown, the connecting arm 30 includes a pair of side wall portions 31 extending in the vertical direction, thus forming left and right side plates. Grooves 34 are symmetrically provided on the left and right side plates. The vertical length of the side wall portion 31 where the groove 34 is located is less than the vertical lengths of the side wall portions 31 on both sides of the groove 34, reducing the cross-sectional area at the groove 34, so that stress concentration occurs, and the radar mounting bracket is more likely to break at the groove 34.

[0052] In one embodiment, the connecting arm 30 includes a first section 35 connected to the first mounting seat 10, a second section 37 connected to the second mounting seat 20, and an intermediate section 36 therebetween; the pair of side wall portions 31 included in the intermediate section 36 are bent laterally, so that the distance between the pair of side wall portions 31 included in the second section 37 is greater than the distance between the pair of side wall portions 31 included in the first section 35;

[0053] wherein, the distance between the side wall portions 31 included in the second section 37 is equal to the width of the second mounting seat 20.

[0054] In the embodiments of the present disclosure, the first section 35, the middle section 36, and the second section 37 of the connecting arm 30 each include a side wall portion 31 and a transverse portion 32. Among them, a pair of side wall portions 31 and the transverse portion 32 included in the first section 35 are both perpendicular to the first mounting seat 10, and the first section 35 extends towards the second mounting seat 20 to form the middle section 36. After the middle section 36 extends a certain distance, it turns and extends in a direction perpendicular to the second mounting seat 20 to form the second section 37. The side wall portions 31 included in the middle section 36 start to bend towards the left and right sides respectively at positions close to the second section 37, improving the anti-yielding property in the left and right directions. On the other hand, the distance between a pair of side wall portions 31 included in the second section 37 is made equal to the width of the second mounting seat, that is, a pair of side wall portions 31 included in the second section 37 partially surround the second mounting seat 20, improving the stability of the second mounting seat 20 and the radar.

[0055] The side wall portion 31 included in the first section 35 is approximately triangular when viewed from the left and right directions. Specifically, the bottom edge of the side wall portion 31 included in the first section 35 is flush with the bottom edge of the first mounting seat 10. The top edge of the side wall portion 31 included in the first section 35 extends towards the second mounting seat 20, such that the vertical length of this side wall portion 31 gradually decreases until it is the same as the vertical length of the side wall portion 31 of the middle section 36. At the same time, when the long hole 33 is used as the structural weakening portion, the long hole 33 is provided in the transverse portions 32 of the middle section 36 and the second section 37, and the transverse portion 32 of the first section 35 is not provided with the long hole 33. When the groove 34 is used as the structural weakening portion, the groove 34 is provided in the side wall portion 31 of the middle section 36 or the second section 37. Thus, the structural strength of the first section 35 is higher than that of the side wall portions 31 of the middle section 36 and the second section 37, so it is difficult for the first section 35 to break, but it is easier for the lower part of the bracket to break, further avoiding the radar from colliding with the front bumper beam due to too high a break position.

[0056] As Figure 3 shown, the top of the side wall portion 31 included in the first section 35 has a weight reduction groove 38 to reduce the weight of the radar mounting bracket.

[0057] In one embodiment, the radar is a lidar.

[0058] In the embodiments of the present disclosure, the lidar generates a high-precision three-dimensional environmental map by emitting laser pulses and measuring the return time, and real-time perceives the objects, obstacles, and terrain around the vehicle. Compared with other sensors such as cameras and millimeter-wave radars, the lidar has higher ranging accuracy and stronger environmental adaptability, and can still maintain a stable detection effect especially in low light or complex weather conditions. Its cost is usually higher than that of other radars, and if it is damaged during a collision, it will greatly increase the vehicle's repair cost.

[0059] LiDAR has multiple mounting positions on a vehicle. The LiDAR mounted on the top of the vehicle usually will not be damaged during a collision. The blind spot supplement LiDAR is usually mounted at the front of the vehicle. The core function of the blind spot supplement LiDAR is to make up for the shortcoming of other sensors in the detection range, especially the blind spots that are difficult to reach during vehicle driving. When the vehicle collides, the blind spot supplement LiDAR is easily damaged because it is located at the front of the vehicle.

[0060] According to the solution of the embodiment of the present disclosure, the blind spot supplement LiDAR mounted in front of the vehicle can be effectively protected.

[0061] In one implementation, the first mounting seat 10, the second mounting seat 20 and the connecting arm 30 are integrally formed of a metal material.

[0062] In the embodiment of the present disclosure, the radar mounting bracket is integrally formed of a metal material, such as aluminum alloy, titanium alloy, carbon steel, etc. So that the radar mounting bracket can carry a LiDAR with a relatively large weight.

[0063] In one implementation, the plane where the first mounting seat 10 is located is perpendicular to the plane where the second mounting seat 20 is located, and the included angle between the length direction of the connecting arm 30 and the first mounting seat 10 or the second mounting seat is any value between 30° and 60°.

[0064] In the embodiment of the present disclosure, the included angles between the length direction of the connecting arm 30 and the first mounting seat 10 and the second mounting seat 20 are both 45°, so as to ensure that the radar is located below the front of the front anti-collision beam, and the impact force is more concentrated on the connecting arm 30. At the same time, the radar is placed forward to reduce the blind spot of the radar. The angles between the three can be adjusted as needed. For example, the included angle between the length direction of the connecting arm 30 and the first mounting seat 10 is 30°, and the included angle with the first mounting seat 10 is 60°.

[0065] The embodiment of the present disclosure adopts the above technical solution to effectively protect the radar when the vehicle collides, thereby reducing the maintenance cost.

[0066] As another aspect of the embodiment of the present disclosure, the embodiment of the present disclosure provides a vehicle, which includes a radar, and the radar is mounted on the vehicle by using the radar mounting bracket 100 provided in any embodiment of the present disclosure.
