Description

Technical Field

[0001] This utility model relates to the field of vehicle accessories technology, and in particular to a multi-angle adjustable mounting base and a vehicle sensor. Background Technology

[0002] With the rapid development of intelligent driving technology, the importance of onboard sensors, serving as the "eyes" and "ears" of the vehicle's environment perception, is becoming increasingly prominent. Various onboard sensors, such as LiDAR, millimeter-wave radar, cameras, and ultrasonic sensors, are the core hardware foundation for realizing Advanced Driver Assistance Systems (ADAS) and autonomous driving functions. These sensors need to be precisely and stably installed on the exterior (such as the roof, bumper, or grille) or interior (such as behind the windshield) of the vehicle to obtain accurate and reliable environmental data.

[0003] In existing technologies, once traditional fixed mounting brackets are assembled, their position and angle are difficult to change, making it impossible to adapt to the differentiated requirements of different vehicle platforms or sensor models, and also preventing convenient calibration and fine-tuning during vehicle assembly or subsequent maintenance. Some mounting brackets with adjustment functions often use simple threaded tightening with sliding grooves or oblong holes, which can achieve a certain degree of position adjustment, but the adjustment process is often cumbersome and time-consuming.

[0004] Therefore, in order to address the above problems, the applicant needs to design a multi-angle adjustable mounting base and vehicle-mounted sensor to solve the problem. Utility Model Content

[0005] On one hand, this application provides a multi-angle adjustable mounting base, including a fixed frame and a connecting frame. A vertical slider is provided on one side of the connecting frame, and a vertical guide rail is slidably mounted on the vertical slider.

An X-axis horizontal guide rail is fixedly mounted below the fixed plate, and an X-axis horizontal slider is slidably mounted below the X-axis horizontal guide rail. A locking mechanism is provided below the X-axis horizontal slider, and the locking mechanism is used to lock the X-axis horizontal guide rail and the X-axis horizontal slider. A positioning mechanism is provided on the outside of the connecting frame, and the positioning mechanism is used to lock the vertical guide rail and the vertical slider.

[0006] Preferably, the locking mechanism includes a stabilizing plate fixedly connected to the X-axis horizontal slider, and a mounting plate is provided below the stabilizing plate. A locking component is provided on the mounting plate, and the locking component is used to abut against and lock the X-axis horizontal guide rail and the X-axis horizontal slider, so that the locking component obtains stable support, improving the reliability of the locking action and the overall structural strength.

[0007] Preferably, the locking assembly includes a clamping member fixedly connected to the mounting plate, and a locking arm is hinged to the clamping member. A locking plate is hinged to the inner side of the locking arm, and the locking plate is hinged to the clamping member. A rotating arm is hinged to the inner side of the locking plate, and a locking head corresponding to the fixed plate is provided at the end of the rotating arm away from the locking plate. The linkage-type locking assembly formed by the hinged locking arm, locking plate, and rotating arm can achieve firm locking and quick release of the guide rail with a small operating force.

[0008] Preferably, an anti-loosening elastic element is sleeved on the hinge shaft of the clamping member and the locking arm, and the anti-loosening elastic element is a torsion spring, with its two ends abutting against the clamping member and the locking arm respectively, for providing a preload force to the locking arm to press its locking end against the X-axis horizontal guide rail. The anti-loosening elastic element provides a continuous preload force, which can automatically compensate for the gap and prevent the lock from loosening due to vehicle vibration, thereby enhancing the locking reliability.

[0009] Preferably, the positioning mechanism includes a stabilizing base fixedly connected to the connecting frame, and a telescopic rod is fixedly provided on one side of the stabilizing base. A connecting plate is fixedly provided at the end of the telescopic rod away from the stabilizing base, and a positioning head corresponding to the moving part is fixedly provided on one side of the connecting plate.

Detailed Implementation

[0017] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0018] Please refer to Figures 1-4This utility model embodiment provides a multi-angle adjustable mounting base, including a fixed frame 1, on which a connecting frame 10 is provided. A vertical slider 11 is provided on one side of the connecting frame 10, and a vertical guide rail 12 is slidably provided on the vertical slider 11. A movable member 13 is provided on one side of the vertical guide rail 12, and a Y-axis horizontal guide rail 14 is fixedly provided below the movable member 13. A Y-axis horizontal slider 15 is slidably provided below the Y-axis horizontal guide rail 14, and a fixed plate 16 is fixedly provided below the Y-axis horizontal slider 15. An X-axis horizontal guide rail 17 is fixedly provided below the fixed plate 16, and an X-axis horizontal guide rail 17 is slidably provided below the X-axis horizontal guide rail 17. The horizontal slider 18 of the X-axis is provided with a locking mechanism 2 below it, which is used to lock the horizontal guide rail 17 and the horizontal slider 18 of the X-axis. The connecting frame 10 is provided with a positioning mechanism 3 on its outer side, which is used to lock the vertical guide rail 12 and the vertical slider 11. The fixed frame 1 is connected to the vertical slider 11 and the vertical guide rail 12 through the connecting frame 10 to realize the Z-axis adjustment. The moving part 13 drives the horizontal guide rail 14 and the horizontal slider 15 of the Y-axis to realize the Y-axis adjustment. The horizontal guide rail 17 and the horizontal slider 18 of the X-axis below the fixed plate 16 realize the X-axis adjustment, thus forming a complete three-dimensional translation adjustment system.

[0019] like Figure 3 As shown, the locking mechanism 2 includes a stabilizing plate 20 fixedly connected to the X-axis horizontal slider 18, and a mounting plate 21 is provided below the stabilizing plate 20. A locking assembly is provided on the mounting plate 21, and the locking assembly is used to abut and lock the X-axis horizontal guide rail 17 and the X-axis horizontal slider 18. The locking assembly includes a clamping member 22 fixedly connected to the mounting plate 21, and a locking arm 23 is hinged to the clamping member 22. A locking plate 24 is hinged to the inner side of the locking arm 23, and the locking plate 24 is hinged to the clamping member 22. A rotating arm 25 is hinged to the inner side of the locking plate 24, and one end of the rotating arm 25 away from the locking plate 24 is provided with a connection to the fixed plate 16. The corresponding locking head 26, the hinge shaft of the clamping member 22 and the locking arm 23 is fitted with an anti-loosening elastic element, which is a torsion spring. Its two ends abut against the clamping member 22 and the locking arm 23 respectively, and are used to provide a preload force to the locking arm 23 so that its locking end presses against the X-axis horizontal guide rail 17. When the locking arm 23 is pressed down, the action is transmitted through the linkage mechanism formed by the locking plate 24 and the rotating arm 25 and drives the locking head 26 to move upward, thereby pressing the fixed plate 16 and the X-axis horizontal guide rail 17 to achieve friction locking. After being released, the anti-loosening elastic element torsion spring causes the locking arm 23 to automatically reset and maintain a certain preload force.

[0020] like Figure 4As shown, the positioning mechanism 3 includes a stabilizing base 30 fixedly connected to the connecting frame 10, and a telescopic rod 31 is fixedly provided on one side of the stabilizing base 30. A connecting plate 32 is fixedly provided at the end of the telescopic rod 31 away from the stabilizing base 30, and a positioning head 33 corresponding to the moving member 13 is fixedly provided on one side of the connecting plate 32. A spring is fixedly provided inside the telescopic rod 31, and the spring is initially in a compressed state. The pre-compressed spring inside the telescopic rod 31 always applies an outward pushing force to the connecting plate 32 and the positioning head 33, so that the positioning head 33 automatically presses against the side of the moving member 13, thereby locking the relative position between the vertical slider 11 and the vertical guide rail 12.

[0021] To improve movement stability, an extension block 34 is fixedly provided on one side of the connecting plate 32, and a slide rail 35 is slidably provided on the end of the extension block 34 away from the connecting plate 32, and the slide rail 35 is fixedly connected to the connecting frame 10.

[0022] like Figure 5 As shown, on the other hand, this application also provides a vehicle sensor with a multi-angle adjustable mounting base, including a multi-angle adjustable mounting base, and a sensor body 19 is provided on the mounting plate 21 in the multi-angle adjustable mounting base.

[0023] In summary, when using this multi-angle adjustable mounting base and vehicle-mounted sensor, the three sets of sliding pairs—vertical slider 11 and vertical guide rail 12, Y-axis horizontal slider 15 and Y-axis horizontal guide rail 14, and X-axis horizontal slider 18 and X-axis horizontal guide rail 17—together achieve the sensor's translational freedom in the X, Y, and Z directions. After the sensor position is initially adjusted, the operator can press the locking arm 23 of the locking mechanism 2 with one hand. Through the linkage mechanism formed by the locking arm 23, the locking arm 24, and the rotating arm 25, the locking head 26 is driven to press the fixing plate 16 and the X-axis horizontal guide rail 17 upwards, thereby firmly locking the X-axis direction. The torsion spring on the hinge shaft provides a continuous anti-loosening pre-tightening force. At the same time, the telescopic rod 31 driven by the pre-compression spring in the positioning mechanism 3 will always push the connecting plate 32 and the positioning head 33 to automatically press the moving part 13. With the guidance of the extension block 34 and the slide rail 35, the vertical direction is instantly self-locked, ultimately completing the rapid, precise adjustment and stable fixation of the sensor in multiple dimensions.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
