Description

Technical Field

[0001] This utility model relates to the field of automotive engineering technology, specifically to a vehicle sensor mounting angle adjustment mechanism. Background Technology

[0002] Against the backdrop of the rapid development of intelligent connected vehicles and autonomous driving technology, vehicle sensors used in NOA testing, such as LiDAR, cameras, and millimeter-wave radar, are key components for realizing environmental perception and autonomous driving functions. The main function of the mounting angle adjustment mechanism of the NOA test vehicle sensors is to provide flexible and precise angle adjustment functions for the sensors, ensuring that the sensor's detection direction and viewing angle meet the design requirements.

[0003] A vehicle sensor mounting angle adjustment mechanism typically consists of a base, a rotation adjustment assembly, a locking device, and an angle detection unit. The base is used to fix the sensor to the vehicle body or chassis, providing stable support for the entire mechanism. The rotation adjustment assembly includes multiple rotating joints and transmission components, enabling multi-angle adjustment of the sensor in the horizontal and vertical directions. The locking device uses bolt fastening, hydraulic locking, or electromagnetic locking to ensure the stable position of the adjusted sensor. The angle detection unit provides real-time feedback on the sensor's current angle through an angle sensor or scale markings.

[0004] However, in actual use, most traditional installation mechanisms can only achieve single adjustment of the sensor in the horizontal or pitch direction, and cannot perform full-dimensional angle adjustment. This makes it difficult to meet the precise monitoring needs of sensors under complex road conditions. For example, when a vehicle is going uphill or downhill or turning, the sensor cannot adjust the horizontal and pitch angles at the same time to obtain the best monitoring angle. In view of this, we propose a vehicle sensor installation angle adjustment mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle sensor mounting angle adjustment mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle sensor mounting angle adjustment mechanism includes a bottom housing, on which one end of a mounting ring is fixedly mounted, and on the other end of the mounting ring, a top housing is fixedly mounted. An adjustment assembly is disposed on the bottom housing, the adjustment assembly comprising:

[0008] A limiting hinge frame is fixedly installed inside the bottom shell. A No. 1 motor is fixedly installed inside the bottom shell. A cylindrical end is fixedly installed at the output end of the No. 1 motor. A large circular plate is fixedly installed at the other end of the cylindrical end. A No. 1 sliding groove is opened on the cylindrical end and the large circular plate.

[0009] Mounting column, the bottom shell is fixedly mounted with a mounting column, a large gear is rotatably mounted on the mounting column, a movable hinge frame is fixedly mounted on the large gear, a mounting cylinder is rotatably mounted on the movable hinge frame, a second sliding groove is opened on the mounting cylinder, one end of a first limiting rod is slidably mounted on the mounting cylinder, and a second limiting rod is hingedly mounted on the other end of the first limiting rod;

[0010] A small circular plate is fixedly installed on the second limiting rod. One end of a spring is fixedly installed on the small circular plate. A second motor is fixedly installed on the bottom outer shell. A small gear is fixedly installed at the output end of the second motor. One end of an installation rod is fixedly installed on the installation cylinder. The other end of the installation rod is fixedly installed with the vehicle sensor body.

[0011] In a further embodiment, multiple sets of the first slide groove, the second slide groove, the first limiting rod, the second limiting rod, the small circular plate, and the spring are provided.

[0012] In a further embodiment, the first limiting rod slides inside the second sliding groove, and the second limiting rod slides inside the first sliding groove.

[0013] In a further embodiment, the large gear meshes with the small gear, the other end of the spring is fixedly mounted on the large circular plate, and the mounting rod is disposed between the bottom outer shell and the top outer shell.

[0014] In a further embodiment, a protective component is provided on the bottom outer shell, a slider is fixedly installed on the mounting rod, an external baffle is fixedly installed on one end of the slider, an internal baffle is fixedly installed on the other end of the slider, and a rubber pad is fixedly installed on the mounting ring.

[0015] In a further embodiment, the slider, outer baffle, inner baffle, and rubber pad are disposed between the bottom housing and the top housing.

[0016] In a further embodiment, the outer baffle is disposed outside the bottom and top outer shells, and the inner baffle is disposed inside the bottom and top outer shells.

[0017] Compared with the prior art, the present invention provides a vehicle sensor mounting angle adjustment mechanism, which has the following advantages:

[0018] 1. The vehicle sensor mounting angle adjustment mechanism, in order to achieve precise control of the sensor mounting angle in all dimensions, is equipped with an adjustment component. This component works with a first motor to drive the cylinder and large circular plate to rotate. Through the meshing transmission of the large gear and the small gear, the mounting cylinder and the mounting tube rotate, realizing the horizontal rotation of the sensor from 0-360°. At the same time, a second motor drives the small gear to finely adjust the speed of the large gear. With the first limit rod sliding in the second slide groove and the second limit rod sliding in the first slide groove, the small circular plate pulls the mounting tube through the spring, realizing the flexible adjustment of the sensor's pitch angle. The elastic pull of the spring can buffer the vibration and impact during vehicle movement, avoid the adjustment mechanism jamming caused by rigid connection, and ensure that the sensor maintains the preset angle under complex road conditions.

[0019] 2. The vehicle sensor mounting angle adjustment mechanism is equipped with a protective component to provide comprehensive operational protection for the sensor. This component, together with the slider on the mounting rod, can slide between the bottom and top housings. The outer baffle and the inner baffle form a double protective barrier: the outer baffle blocks the direct impact of road debris on the sensor, and the inner baffle prevents the adjustment component from shifting due to vibration. At the same time, the rubber pad on the mounting ring ensures that the slider contacts it during movement, avoiding excessive impact and reducing the risk of vibration damage to the internal components of the sensor.

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0031] A vehicle sensor mounting angle adjustment mechanism includes a bottom housing 1, one end of a mounting ring 2 is fixedly mounted on the bottom housing 1, and the other end of the mounting ring 2 is fixedly mounted on a top housing 3.

[0032] In one embodiment of this utility model, an adjustment component 4 is provided on the bottom outer shell 1. The adjustment component 4 includes a limiting hinge frame 41. The limiting hinge frame 41 is fixedly installed inside the bottom outer shell 1. A first motor 42 is fixedly installed inside the bottom outer shell 1. One end of a cylinder 43 is fixedly installed at the output end of the first motor 42. A large circular plate 44 is fixedly installed at the other end of the cylinder 43. A first sliding groove 45 is opened on the cylinder 43 and the large circular plate 44. An installation column 46 is fixedly installed on the bottom outer shell 1. A large gear 47 is rotatably installed on the installation column 46. A movable hinge frame 48 is fixedly installed on the large gear 47. An installation cylinder 49 is rotatably installed on the movable hinge frame 48. A second sliding groove 410 is opened on the installation cylinder 49. One end of a first limiting rod 411 is slidably installed on the installation cylinder 49. A second limiting rod 412 is hingedly installed at the other end of the first limiting rod 411. A small circular plate 413 is fixedly installed on the second limiting rod 412. One end of a spring 414 is fixedly installed on the small circular plate 413. A second motor 415 is fixedly installed on the bottom outer shell 1. A small gear 416 is fixedly installed on the output end of the second motor 415. One end of an installation rod 417 is fixedly installed on the installation cylinder 49. The other end of the installation rod 417 is fixedly installed with a vehicle sensor body 418. Multiple sets of first slide groove 45, second slide groove 410, first limiting rod 411, second limiting rod 412, small circular plate 413 and spring 414 are provided. The first limiting rod 411 slides inside the second slide groove 410. The second limiting rod 412 slides inside the first slide groove 45. The large gear 47 meshes with the small gear 416. The other end of the spring 414 is fixedly installed on the large circular plate 44. The installation rod 417 is located between the bottom outer shell 1 and the top outer shell 3.

[0033] In this embodiment, after the vehicle sensor body 418 is installed, the first motor 42 is started, driving the cylinder 43 and the large circular plate 44 to rotate around the axis. Simultaneously, the large gear 47 on the outer side of the cylinder 43 meshes with the small gear 416. When the first motor 42 drives the cylinder 43 to rotate, the large gear 47 rotates accordingly, driving the mounting cylinder 49 to perform a circular motion around the mounting column 46, achieving a 360° continuous horizontal rotation of the vehicle sensor body 418. Simultaneously, by controlling the forward and reverse rotation and rotation angle of the first motor 42, the horizontal orientation of the sensor can be precisely adjusted. Simultaneously, the second motor 415 is started, driving the small gear 416 to rotate. Through the difference in meshing with the large gear 47, the mounting cylinder 49 produces a slight angular displacement relative to the cylinder 43. The first limiting rod 411, which slides within the second sliding groove 410, moves with the angular displacement of the mounting cylinder 49. The second limiting rod 412, which is hinged at its end, slides within the first sliding groove 45 of the large circular plate 44, pushing the small circular plate 413 to move radially. At the same time, one end of the spring 414 on the small circular plate 413 is fixed to the large circular plate 44, and the other end pulls the mounting cylinder 49 to swing around the movable hinge frame 48 through elastic force, which can provide a stable pulling force and buffer the vibration and impact during vehicle movement. During operation, the first motor 42 and the second motor 415 can work simultaneously to achieve compound adjustment of rotation and pitch angles. During vehicle turning, the system can adjust the horizontal rotation angle and pitch angle of the sensor in real time according to the vehicle speed and steering angle to ensure that the sensor is always aligned with the target area.

[0034] In one embodiment of this utility model, a protective component 5 is provided on the bottom outer shell 1, a slider 51 is fixedly installed on the mounting rod 417, an outer baffle 52 is fixedly installed on one end of the slider 51, an inner baffle 53 is fixedly installed on the other end of the slider 51, and a rubber pad 54 is fixedly installed on the mounting ring 2. The slider 51, the outer baffle 52, the inner baffle 53 and the rubber pad 54 are disposed between the bottom outer shell 1 and the top outer shell 3. The outer baffle 52 is disposed outside the bottom outer shell 1 and the top outer shell 3, and the inner baffle 53 is disposed inside the bottom outer shell 1 and the top outer shell 3.

[0035] In this embodiment, the outer baffle 52 is tightly attached to the outer walls of the bottom outer shell 1 and the top outer shell 3, and the inner baffle 53 is tightly attached to the inner walls of the bottom outer shell 1 and the top outer shell 3. When vibration occurs during vehicle operation, the inner baffle 53 prevents the mounting rod 417 from displacing excessively through a limiting effect, ensuring stable sensor angle adjustment accuracy. At the same time, when the slider 51 moves with the mounting rod 417, the rubber pad 54 slides in contact with the slider 51, providing a buffering effect. During the sensor angle adjustment process, the slider 51 moves synchronously with the mounting rod 417, and the outer baffle 52, the inner baffle 53, and the rubber pad 54 always maintain their protective functions.
