Description

Technical Field

[0001] This utility model relates to the field of radar equipment technology, specifically to a mounting bracket for laser and millimeter-wave radar used in unmanned driving. Background Technology

[0002] LiDAR achieves centimeter-level high-precision detection with extremely short wavelengths, but is susceptible to interference from rain and fog. Millimeter-wave radar, using the 77GHz band, boasts strong environmental adaptability and low cost. Based on the complementary nature of their principles, modern autonomous driving systems often employ a hybrid configuration of LiDAR and millimeter-wave radar, achieving functional synergy through a multi-sensor fusion architecture: millimeter-wave radar dominates in complex weather or long-range detection scenarios, switching to LiDAR for high-precision positioning, thus ensuring reliable all-weather perception. To expand the detection field of view, the radar system of autonomous vehicles is typically mounted on the vehicle's roof using a dedicated mounting bracket.

[0003] As per existing technology, patent CN208715104U discloses a radar bracket for autonomous vehicle radar, comprising two support legs, a base plate fixed to the top of the two support legs, and a bracket housing fitted onto the top of the base plate. The bracket housing comprises two integrally formed thick shells located on both sides of the bracket housing. Short slides welded to the thick shells are provided on both sides of the bottom of the bracket housing. The two sides of the base plate are vertically slidably connected between the two short slides via pulleys. A solid tube is fixed to the center of the top of the base plate. This radar bracket for autonomous vehicle radar ensures the stability of the radar during placement by setting up a radar platform, and the cooperation between the bracket housing, plastic upper plate, and plastic lower plate ensures that the accuracy of real-time measurement data is not affected by vibration, thereby ensuring driving safety.

[0004] The stents in the aforementioned patents still have certain drawbacks: Although the aforementioned bracket ensures the stability of the radar during placement by setting up a radar platform, its design is only suitable for single-radar deployment scenarios. Given the high redundancy requirements of autonomous driving systems for environmental perception, it is usually necessary to deploy lidar and millimeter-wave radar simultaneously to achieve reliable all-weather detection through functional complementarity. However, this radar bracket adopts a single radar platform design, and its spatial layout and fixing method only support the independent installation of a single radar, which cannot meet the physical installation requirements and electrical interface compatibility requirements for dual-radar collaborative operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a mounting bracket for laser and millimeter-wave radar used in autonomous driving, which can simultaneously mount laser radar and millimeter-wave radar.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mounting bracket for laser and millimeter-wave radar for unmanned driving, comprising a bracket, the bracket being U-shaped, a mounting plate being fixedly connected to the upper end of the inner side of the bracket, second bolts being threadedly connected to both sides of the mounting plate, a positioning plate being slidably connected to the top of the bracket near the mounting plate, and first bolts being slidably connected to both ends of the positioning plate, the lower end of the first bolts penetrating the positioning plate and being threadedly connected to the bracket.

[0007] Furthermore, the bracket has limit grooves at both ends on the side near the mounting plate at the top, and limit blocks are slidably connected inside the limit grooves. The top of the limit blocks is fixedly connected to the positioning plate.

[0008] Furthermore, the end of the limiting block is trapezoidal.

[0009] Furthermore, the bottom of the mounting plate is provided with a sliding groove, and both ends of the sliding groove are slidably connected to sliders, and the bottom of the sliders is fixedly connected to a support plate.

[0010] Furthermore, the end of the slider is trapezoidal, and a magnetic block is fixedly connected to the top of the slider.

[0011] Furthermore, a limiting plate is provided at the upper end of the mounting plate on the side away from the bracket, and the limiting plate is fixedly connected to the bracket.

[0012] Furthermore, a reinforcing plate is provided between the bracket and the mounting plate, and the two sides of the reinforcing plate are fixedly connected to the bracket and the mounting plate respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This type of laser and millimeter-wave radar mounting bracket for autonomous driving involves first fixing the bracket to the top of the vehicle, then placing the laser radar between the positioning plate and the bracket, and pushing the positioning plate to press and fix the laser radar in place. Next, the first bolt is tightened, and then the millimeter-wave radar is placed flush against the mounting plate and fixed with the second bolt. This design can simultaneously fix both laser and millimeter-wave radar, meeting the physical installation requirements of dual-radar collaboration in autonomous driving systems, achieving functional complementarity between the two, and ensuring reliable all-weather environmental perception.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4 A mounting bracket for laser and millimeter-wave radar for autonomous driving includes a bracket 1, which is U-shaped. A mounting plate 6 is fixedly connected to the upper end of the inner side of the bracket 1. Second bolts 11 are threadedly connected to both sides of the mounting plate 6. A positioning plate 3 is slidably connected to the top of the bracket 1 near the mounting plate 6. First bolts 5 are slidably connected to both ends of the positioning plate 3. The lower end of the first bolt 5 passes through the positioning plate 3 and is threadedly connected to the bracket 1.

[0018] The laser and millimeter-wave radar mounting bracket for autonomous driving described in this utility model is used by first fixing the bracket 1 to the top of the vehicle, then placing the laser radar 14 between the positioning plate 3 and the bracket 1, and pushing the positioning plate 3 to press and fix the laser radar 14. Then, tighten the first bolt 5, and then place the millimeter-wave radar 15 on the mounting plate 6 and fix it with the second bolt 11. It can fix both the laser radar 14 and the millimeter-wave radar 15 at the same time, meeting the physical installation requirements of dual radar collaboration in autonomous driving systems, realizing the complementary functions of the two, and ensuring the reliability of all-weather environmental perception.

[0019] like Figure 2 and Figure 3 As shown, limit grooves 2 are provided at both ends of the top of the bracket 1 near the mounting plate 6. Limit blocks 4 are slidably connected inside the limit grooves 2, and the top of the limit blocks 4 is fixedly connected to the positioning plate 3.

[0020] Specifically, the top of the bracket 1 is provided with a limiting groove 2 that slides with the limiting block 4 at the bottom of the positioning plate 3, so that the positioning plate 3 is more stable and does not shift when adjusting its position, which facilitates precise fixing of the lidar 14.

[0021] like Figure 3 As shown, the end of the limiting block 4 is trapezoidal. The trapezoidal limiting block 4 makes the positioning plate 3 slide more smoothly and less prone to jamming.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, a groove 7 is provided at the bottom of the mounting plate 6, and sliders 8 are slidably connected to both ends of the groove 7. A support plate 9 is fixedly connected to the bottom of the sliders 8.

[0023] Specifically, the bottom groove 7 of the mounting plate 6, together with the slider 8 and the support plate 9, allows for flexible adjustment of the position of the support plate 9 to facilitate pre-fixation of the millimeter-wave radar 15 and subsequent tightening of the second bolt 11.

[0024] like Figure 2 and Figure 4 As shown, the end of the slider 8 is trapezoidal, and a magnetic block 10 is fixedly connected to the top of the slider 8.

[0025] Specifically, the trapezoidal design at the end of the slider 8 makes the sliding smoother, and the magnetic block 10 at the top of the slider 8 can fix the position of the slider 8 to prevent the tray 9 from shifting and causing the tray 9 to lose its pre-fixing effect.

[0026] like Figure 3 As shown, a limiting plate 13 is provided at the upper end of the mounting plate 6 on the side away from the bracket 1, and the limiting plate 13 is fixedly connected to the bracket 1.

[0027] Specifically, the limiting plate 13 on the side of the mounting plate 6 can restrict the upper end of the millimeter-wave radar 15, making it easier to fix the millimeter-wave radar 15.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a reinforcing plate 12 is provided between the bracket 1 and the mounting plate 6, and the two sides of the reinforcing plate 12 are fixedly connected to the bracket 1 and the mounting plate 6 respectively.

[0029] Specifically, the reinforcing plate 12 between the bracket 1 and the mounting plate 6 enhances the connection strength, can stably bear the weight of the dual radars, reduce the impact of vibration on the radar, improve the durability of the bracket 1 and the stability of radar detection, and meet the high reliability requirements of autonomous driving.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
