Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle-mounted radar installation equipment, specifically relating to a radar mounting bracket and radar installation structure. Background Technology

[0002] In unmanned driving systems for mining dump trucks, the onboard sensing units involve various types, structural forms, and radar devices with multi-angle coverage requirements. The installation and fixation of these radar devices on the mining dump trucks requires consideration not only of the radar itself but also of the structure and installation locations of different mining dump truck models. Furthermore, it necessitates consideration of the installation position and coverage angle on the mining dump truck, as well as the robustness and stability of the radar mounting bracket structure. While existing radar mounting brackets include anti-rock-flying shield designs suitable for mining conditions, they still suffer from numerous problems, such as the incompatibility of mounting brackets across various vehicle models leading to cumbersome installation; the dispersed installation and chaotic wiring of onboard radars to meet horizontal field-of-view coverage requirements; the high vibration and impact conditions in mining environments resulting in short radar lifespan; and the difficulty in adjusting the radar elevation angle range at different vehicle installation heights. Therefore, it is necessary to design a new radar mounting bracket suitable for unmanned driving systems for mining dump trucks. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a radar mounting bracket and radar mounting structure with good field of view coverage that is applicable to different types of mining dump trucks.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] Based on one aspect of this utility model, a radar mounting bracket is provided, including a box-type main mounting base and two mounting platform modules disposed within the box-type main mounting base. Each of the mounting platform modules includes a vibration-damping base connected to the box-type main mounting base and a mounting platform connected to the vibration-damping base. The mounting platform is designed as a trapezoidal or wedge-shaped body for adjusting the radar elevation angle. The two mounting platforms are installed opposite each other and their relative positions satisfy the requirement that the horizontal field of view of the two radars covers 180°.

[0006] In one embodiment, the box-type main mounting base has two identical sets of waist holes opposite to the two mounting platform modules, and any one of the mounting platform modules is detachably connected to the box-type main mounting base by bolts.

[0007] In one embodiment, the vibration damping base includes a base detachably connected to the box-type main mounting base and a plurality of rubber vibration dampers detachably connected to the base.

[0008] In one embodiment, the mounting platform has a countersunk hole relative to the vibration damper, and the mounting platform is detachably connected to the vibration damper by countersunk screws.

[0009] In one embodiment, the vibration damping base is detachably connected to the inner surface of the box-type main mounting base, and the mounting platform is detachably connected to the vibration damping base.

[0010] In one embodiment, the mounting platform is further provided with an elastic buffer pad.

[0011] In one embodiment, the surface of the mounting platform on which the radar is mounted is recessed with a weight-reducing groove.

[0012] In one embodiment, the box-type main mounting base is provided with a protective cover with a viewing window and a cable outlet corresponding to the two radars.

[0013] In one embodiment, the back of the box-type main mounting base has four mounting holes.

[0014] In another aspect, this utility model provides a radar mounting structure, including two radars and a radar mounting bracket as described in any of the preceding claims, wherein the two radars are detachably mounted on two mounting platform modules.

[0015] Compared with existing technologies, the radar mounting bracket and radar mounting structure of this utility model, through the design of two mounting platform modules, allows two radars to be installed at an angle to each other. A single set of mechanisms can achieve unidirectional full-angle coverage of the radar sensing unit of the unmanned mining dump truck. While ensuring good spectral coverage, the overall structure is refined and compact. Two sets of radar mounting platform modules are integrated into one bracket assembly, occupying little space. Compared with decentralized installation, it not only improves aesthetics but also has higher space efficiency, while significantly reducing installation difficulty and facilitating large-scale, modular vehicle installation operations. The pitch angle of a single radar can be adjusted by changing the mounting platform, which can adapt to the installation needs of mining dump trucks of different heights and sizes. Except for the working surface directly in front of the radar, other directions and cable plugs are all covered by the baffle of the box-type main mounting base, providing effective protection for the radar and helping to extend its service life. A vibration damper is added under the radar mounting platform to effectively reduce the impact of vibration and impact during vehicle operation on the radar, further extending the radar's service life.

[0023] See also Figure 1-6 This embodiment provides a radar mounting structure, including two radars 4 and as shown in the figure. Figure 4 The radar mounting bracket shown allows the two radars 4 to be detachably mounted on the two mounting platform modules.

[0024] In this embodiment, the radar mounting bracket includes a box-type main mounting base 1 and two mounting platform modules disposed within the box-type main mounting base 1. Each mounting platform module includes a vibration-damping base 2 connected to the box-type main mounting base 1 and a mounting platform 3 connected to the vibration-damping base 2. The mounting platform 3 is designed as a trapezoidal or wedge-shaped body for adjusting the radar's pitch angle. The two mounting platforms 3 are installed opposite each other, and their relative positions satisfy the requirement that the horizontal field of view of the two radars covers 180°. Unmanned mining dump trucks must achieve omnidirectional forward perception to ensure blind-spot-free detection. Therefore, the working field of view of the forward-facing lidar needs to cover the entire front, i.e., 180 degrees. The horizontal field of view of a single lidar is approximately 120 degrees. Figure 2As shown, this embodiment employs two sets of lidars installed at a 60-degree angle to each other, achieving comprehensive forward coverage without blind spots and ensuring an actual field of view coverage of 180 degrees. By using a combination design of two mutually angled mounting platform modules, the radar achieves unidirectional full coverage of the horizontal field of view. In the radar mounting bracket, the mounting platform 3 of a single radar module adopts a trapezoidal aluminum block design, with multiple aluminum blocks of different angles (such as 4°, 7°, and 10°) available. Simply changing the mounting platform at different tilt angles allows for adjustment of the radar's elevation angle, meeting the need for adjustable radar elevation angles at different installation heights. Furthermore, the use of aluminum mounting platforms effectively reduces the overall weight.

[0025] In this embodiment, the vibration damping base 2 includes a base 21 detachably connected to the box-type main mounting base 1 and four rubber vibration dampers 23 detachably connected to the base 21. The bottom of the mounting platform 3 for a single radar 4 is equipped with four rubber vibration dampers 23, which are evenly distributed around the radar 4, effectively absorbing the impact of vehicle vibration on the radar and thus extending the radar's service life. The surface of the mounting platform 3 where the radar is mounted is recessed with weight-reducing grooves 33. The mounting platform 3 has countersunk holes relative to the vibration dampers 23, and the mounting platform 3 is detachably connected to the vibration dampers 23 by countersunk screws. This avoids interference between the bolts connecting the vibration dampers 23 to the radar 4 on the mounting platform 3 and ensures overall aesthetics.

[0026] In this embodiment, the box-type main mounting base 1 has two identical sets of waist holes opposite to the two mounting platform modules. Either base 21 is detachably connected to the box-type main mounting base 1 via bolts. The waist holes facilitate fine-tuning of the horizontal position of the radar 4 relative to the box-type main mounting base 1. The box-type main mounting base 1 has protective covers 11 with viewing windows and cable exit holes 13 corresponding to the two radars. Four mounting holes 15 are provided on the back of the box-type main mounting base 1. The protective covers 11 are connected to the box-type main mounting base 1 via bolts. Viewing windows are provided on the working surface directly in front of each radar 4, ensuring that the normal operation of the radar 4 is not hindered while effectively preventing damage to the radar 4 from falling rocks. The box-type main mounting base 1 only has openings on the working surface of the radar 4 and at the cable exit point; the rest is covered by protective plates, providing effective protection for the radar in a mining environment. The two cable exit holes 13 are used for centralized cabling of the two radars, and the integrated structural design solves the wiring chaos problem caused by dispersed radar installation. The four mounting holes 15 at the rear of the box-type main mounting base 1 are integrally installed on the front bumper of the unmanned mining dump truck. Before installation, only four mounting holes and two cable outlet holes need to be drilled at the corresponding positions on the front bumper of the vehicle, ensuring convenient installation and meeting the needs of subsequent radar replacement. The radar mounting bracket adopts an integrated box-type structure design, and the radar and mounting platform modules can be assembled in the factory and installed as a whole on site. It adopts universal and simple installation interfaces such as mounting holes 15 and bolts, making it suitable for various models of mining dump trucks and reducing the difficulty of radar installation, which facilitates later maintenance. The left and right sets of mounting platform modules and the bottom mounting interface are completely identical, giving the two sets of radar modules good interchangeability. In this embodiment, an elastic buffer pad can also be set between the mounting platform 3 and the radar 4. The elastic buffer pad can better buffer the impact on the radar 4 under mining conditions, making the radar 4 more stably installed on the mounting platform 3.

[0027] The radar mounting structure in this embodiment uses a two-mounting-platform module design to allow the two radars to be installed at an angle to each other. A single mechanism can achieve unidirectional full-angle coverage of the radar sensing unit of the unmanned mining dump truck. While ensuring good spectral coverage, the overall structure is refined and compact. Two sets of radar mounting platform modules are integrated into one bracket assembly, occupying little space. Compared with decentralized installation, it not only improves aesthetics but also has higher space efficiency, while significantly reducing installation difficulty and facilitating large-scale, modular installation operations. The pitch angle of a single radar can be adjusted by changing the mounting platform, which can adapt to the installation needs of mining dump trucks of different heights and sizes. Except for the working surface directly in front of the radar, all other directions and cable plugs are covered by the baffle of the box-type main mounting base, providing effective protection for the radar and helping to extend its service life. A vibration damper is installed under the radar mounting platform to effectively reduce the impact of vibration and impact during vehicle operation on the radar, further extending the radar's service life.
