Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted radar installation, in particular to an automatically adjustable vehicle-mounted radar bracket. Background Art

[0002] On-board radar is a key component of advanced automotive safety and assisted driving systems. It utilizes electromagnetic wave technology to detect the surrounding environment, emitting electromagnetic waves and receiving reflected waves to accurately determine the target's distance, speed, angle, and other information. There are various types of radar, including millimeter-wave radar, which is less affected by weather and has high detection accuracy; lidar, which can generate high-precision three-dimensional point cloud maps; and ultrasonic radar, which is low-cost and excels at close range detection. These characteristics enable on-board radar to automatically adjust vehicle speed and distance in adaptive cruise control, promptly identify obstacles ahead and trigger braking during automatic emergency braking, and assist with functions such as lane keeping and lane change assistance. This significantly enhances driving safety and convenience, making it an essential component in realizing intelligent and autonomous vehicles.

[0003] Vehicle-mounted radars are typically mounted on the vehicle using a bracket. This bracket provides support for the radar and ensures it is properly positioned. The constant changes in the vehicle's speed and posture during driving, such as acceleration, deceleration, cornering, and uphill and downhill slopes, can cause the radar's optimal detection angle to shift. Furthermore, different driving environments, such as urban congestion, highway driving, and complex rural terrain, require different detection ranges and angles, necessitating adaptive adjustment of the radar's detection angle. However, traditional radar brackets can only adjust the radar's mounting angle during installation, making it impossible for the radar to adapt to road conditions while driving. Furthermore, traditional mounting brackets offer limited angle adjustment, limiting the radar's detection capabilities, impacting the accuracy and reliability of radar-based safety assistance systems and reducing driving safety. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] The present invention uses an on-board intelligent system to perceive the vehicle body posture in real time, analyze and match the optimal detection angle of the current on-board radar body, and send a control signal to the intelligent control unit. The intelligent control unit controls the adjustment mechanism A and the adjustment mechanism B to perform corresponding operations.

[0035] See also Figures 1-11 The present invention provides an automatically adjustable vehicle-mounted radar bracket. The embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention.

[0036] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection", and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0037] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0039] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0040] The vehicle-mounted radar bracket includes a base plate 1, columns 11 evenly distributed on the base plate 1, and a base plate 12 fixed to the ends of the columns 11. The base plate 12 has a first boss 2, and the two ends of the first boss 2 extend to both sides of the base plate 12 respectively. A first spherical cavity 21 is provided on the first boss 2, and the first spherical cavity 21 passes through the two end surfaces of the first boss 2 respectively. A first sphere 3 is movably installed in the first spherical cavity 21, and the first sphere 3 is exposed to both sides of the base plate 12 respectively.

[0041] The first sphere 3 and the second boss 31 on its surface are jointly provided with a second spherical cavity 33. The second boss 31 is provided on one of the exposed parts of the first sphere 3. A traction cylinder 34 is fixed to the other exposed part of the first sphere 3 and opposite to the second boss 31. The second spherical cavity 33 passes through the end face of the second boss 31. The second sphere 4 is movably fitted in the second spherical cavity 33. The second sphere 4 is exposed to the outside of the second boss 31. The mounting plate 13 that provides an installation position for the vehicle-mounted radar body 01 is fixed on the outer wall of the second sphere 4. On the seat 42, the connecting seat 42 is provided on the surface of the second sphere 4 exposed to the outside of the second boss 31, wherein the side of the vehicle-mounted radar body 01 has a mounting foot 011, and the mounting foot 011 is fixed to the mounting plate 13 by a fastening screw. By fastening the mounting foot 011 to the mounting plate 13 using the fastening screw, the vehicle-mounted radar body 01 can be fixed to the mounting plate 13 to realize the installation of the vehicle-mounted radar body 01. The first sphere 3 and the second sphere 4 are respectively movably arranged to provide an adjustable capability for the detection angle of the vehicle-mounted radar body 01.

[0042] A give-way cavity 32 is provided in the first sphere 3, and the give-way cavity 32 is communicated with the second spherical cavity 33 and the traction cylinder 34 respectively. A traction rod 41 is fixed to the side of the second sphere 4 opposite to the connecting seat 42. The traction rod 41 passes through the give-way cavity 32 and the traction cylinder 34 in sequence and extends to the outside of the traction cylinder 34. An adjustment mechanism A8 and an adjustment mechanism B9 are provided on the base plate 1. Both the adjustment mechanism A8 and the adjustment mechanism B9 are controlled by the vehicle-mounted intelligent control unit.

[0043] The adjustment mechanism A8 is connected to the traction cylinder 34, and is used to drive the first sphere 3 to perform a primary deflection adjustment. The adjustment mechanism B9 is connected to the traction rod 41, and is used to drive the second sphere 4 to perform a secondary deflection adjustment based on the primary deflection adjustment, so as to realize two-dimensional adjustment of the detection angle of the vehicle-mounted radar body 01.

[0044] When the on-board intelligent system senses that the vehicle body posture has changed due to factors such as load changes, road undulations (uphill, downhill, and bumpy roads), it analyzes and matches the optimal detection angle of the current on-board radar body 01 in real time, and sends a control signal to the intelligent control unit. The intelligent control unit controls the adjustment mechanism A8 and the adjustment mechanism B9 to perform corresponding operations. The adjustment mechanism A8 drives the first sphere 3 to perform deflection adjustment, and the adjustment mechanism B9 drives the second sphere 4 to perform deflection adjustment, thereby realizing adaptive adjustment of the detection angle of the on-board radar body 01, so that the radar always maintains the optimal detection angle and ensures driving safety.

[0045] In addition, based on the adjustment mechanism A8 driving the first sphere 3 to perform a deflection adjustment once, the adjustment mechanism B9 drives the second sphere 4 to continue to perform a secondary deflection adjustment. The two adjustments are combined with each other to increase the flexibility and precision of the angle adjustment. The adjustment range is large and the degree of freedom is high, reducing the detection blind spots caused by the limited adjustment range. Compared with the traditional single adjustment method, it can better adapt to various complex road conditions and changes in vehicle body posture, ensuring that the radar can capture target information in all directions and multiple angles, thereby significantly improving driving safety.

[0046] See also Figures 7 to 10 The adjustment mechanism A8 includes a driving device A81, a moving seat A82, a gear A85 and a micro electric cylinder A86. A ring body A5 and a ring body B6 are fixed on the base plate 1. The two are coaxially arranged, and the ring body B6 is located inside the ring body A5. Teeth A61 are evenly distributed on the outer edge wall of the ring body B6, and an annular limiting groove A51 is provided on the inner edge wall of the ring body A5. The moving seat A82 is arranged between the ring body A5 and the ring body B6. A guide wheel A83 is rotatably installed on one side of the moving seat A82, and a shaft A84 is rotatably installed on the other side. The guide wheel A83 is limited and mounted in the limiting groove A51. The gear A85 is fixed on the shaft A84 and engages with the teeth A61 accordingly. The guide wheel A83 is limited and clamped in the limit groove A51, and the gear A85 is engaged with the tooth A61, so that the movable seat A82 can be limited between the ring body A5 and the ring body B6. The driving device A81 is set on the movable seat A82, and is used to drive the shaft A84 to rotate. Through the operation of the driving device A81, the shaft A84 is driven to rotate, and the rotating shaft A84 drives the gear A85 to rotate. Under the meshing cooperation of the gear A85 and the tooth A61 and the limiting guiding cooperation of the guide wheel A83 and the limit groove A51, the movable seat A82 can be driven in reverse to move and adjust in the annular space between the ring body A5 and the ring body B6, thereby realizing the change of the deflection adjustment point.

[0047] There is a first annular groove 341 on the outer wall of the traction cylinder 34, and a first annular component 342 is installed in the first groove 341 for limited rotation. One end of the micro electric cylinder A86 is hinged to the top of the moving seat A82 through the hinge seat A861, and the other end is hinged to the outer peripheral wall of the first annular component 342 through the hinge seat B862. The rotation ability of the first annular component 342 enables the micro electric cylinder A86 and the traction cylinder 34 to have the ability to rotate relative to each other, thereby avoiding the synchronous rotation of the first sphere 3 during the movement of the moving seat A82. The telescopic operation of the micro electric cylinder A86 can drive the first sphere 3 to perform corresponding deflection, thereby realizing a one-time adjustment of the detection angle of the vehicle-mounted radar body 01.

[0048] Specifically, the driving device A81 includes a bracket A811, a driving motor A812 and a worm A813. The driving motor A812 is fixed on the top of the movable seat A82 through the bracket A811. The worm A813 is fixed on the output shaft of the driving motor A812. A worm gear A814 is fixed on the shaft A84, and the worm gear A814 is engaged with the worm A813 accordingly.

[0049] Drive motor A812 is controlled by the onboard intelligent control unit. The output shaft of drive motor A812 rotates worm A813. The rotating worm A813 engages worm wheel A814, which in turn rotates shaft A84, providing drive for the rotation of shaft A84. Furthermore, the one-way transmission between worm A813 and worm wheel A814 creates a self-locking effect when drive motor A812 is not operating, helping to maintain the deflected state of first sphere 3 and preventing excessive load on the output shaft of drive motor A812, which could lead to further damage.

[0050] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 11 The adjustment mechanism B9 includes a driving device B91, a moving seat B92, a gear B95 and a micro electric cylinder B96. A limiting column 7 is fixed on the base plate 1. The limiting column 7 is coaxial with the ring body B6. The inner edge wall of the ring body B6 is evenly distributed with teeth B62. An annular limiting groove B71 is provided on the outer edge wall of the limiting column 7. The moving seat B92 is arranged between the ring body B6 and the limiting column 7. A guide wheel B93 is rotatably installed on one side of the moving seat B92, and a shaft B94 is rotatably installed on the other side. The guide wheel B93 is limited and clamped in the limiting groove B71. The gear B95 is fixed on the shaft B94 and engages with the teeth B62 accordingly. The guide wheel B93 is used to limit It is clamped in the limiting groove B71, and the gear B95 is engaged with the tooth B62, so that the movable seat A82 can be limited between the ring body B6 and the limiting column 7. The driving device B91 is set on the movable seat B92, and is used to drive the shaft B94 to rotate. Through the operation of the driving device B91, the shaft B94 is driven to rotate, and the rotating shaft B94 drives the gear B95 to rotate. Under the meshing cooperation of the gear B95 and the tooth B62 and the limiting guide cooperation of the guide wheel B93 and the limiting groove B71, the movable seat B92 can be driven in reverse to move and adjust in the annular space between the ring body B6 and the limiting column 7, thereby realizing the change of the deflection adjustment point.

[0051] There is a second annular groove 411 on the outer wall of the traction rod 41, and a second annular component 412 is installed in the second groove 411 for limited rotation. One end of the micro electric cylinder B96 is hinged to the top of the moving seat B92 through the hinge seat C961, and the other end is hinged to the outer peripheral wall of the second annular component 412 through the hinge seat D962. The rotation ability of the second annular component 412 enables the micro electric cylinder B96 and the traction rod 41 to have the ability to rotate relative to each other, thereby avoiding the synchronous rotation of the second sphere 4 during the movement of the moving seat B92. The micro electric cylinder B96 can drive the second sphere 4 to perform corresponding deflection through the extension and contraction of the micro electric cylinder B96, thereby realizing secondary adjustment of the detection angle of the vehicle-mounted radar body 01.

[0052] Specifically, the driving device B91 includes a bracket B911, a driving motor B912 and a worm B913. The driving motor B912 is fixed on the top of the movable seat B92 through the bracket B911. The worm B913 is fixed on the output shaft of the driving motor B912. A worm gear B914 is fixed on the shaft B94, and the worm gear B914 is engaged with the worm B913.

[0053] Drive motor B912 is controlled by the onboard intelligent control unit. The output shaft of drive motor B912 rotates worm B913, which engages worm wheel B914 and drives shaft B94, providing drive for shaft B94. Furthermore, the one-way transmission between worm B913 and worm wheel B914 creates a self-locking effect when drive motor B912 is not operating, helping to maintain the deflected state of second sphere 4 and preventing excessive load on the output shaft of drive motor B912, which could lead to further damage.

[0054] Through the design of adjustable positions of the movable seat A82 and the movable seat B92, the first sphere 3 and the second sphere 4 can be deflected and adjusted in multiple directions. The two cooperate with each other to further expand the range of detection angle adjustment of the vehicle-mounted radar body 01 and improve the degree of freedom of detection angle adjustment of the vehicle-mounted radar body 01.

[0055] In addition, the adjustment mechanism A8 is arranged on the periphery of the adjustment mechanism B9, and the adjustment mechanism A8 and the adjustment mechanism B9 are independent of each other. Therefore, there will be no blocking interference between the components of the adjustment mechanism A8 and the components of the adjustment mechanism B9, thereby ensuring that the movable seat A82 and the movable seat B92 can be adjusted around the axis of the ring body A5.

[0056] like Figure 2 As shown, restraining springs 14 are provided at the four corners of the lower surface of the mounting plate 13. Each restraining spring 14 extends along the length direction of the column 11. One end of the restraining spring 14 is fixed to the mounting plate 13, and the other end is fixed to the surface of the base plate 1.

[0057] The restraining spring 14 is used to restrain and limit the mounting plate 13 from four points. On the one hand, the first annular member 342 is combined with the traction cylinder 34 and the micro electric cylinder A86 to provide the ability to rotate relative to each other. The second annular member 412 is combined with the traction rod 41 and the micro electric cylinder B96 to provide the ability to rotate relative to each other, thereby preventing the moving seat A82 and the moving seat B92 from driving the first sphere 3 and the second sphere 4 to move synchronously when adjusting their positions.

[0058] When the micro electric cylinder A86 extends and contracts to drive the first sphere 3 to deflect and the micro electric cylinder B96 extends and contracts to drive the second sphere 4 to deflect, since the restraining spring 14 has the ability of elastic deformation, the mounting plate 13 can adapt to the posture changes of the vehicle-mounted radar body 01 when the detection angle is adjusted.

[0059] like Figure 2 As shown, two auxiliary reinforcing ribs 101 with wedge-shaped cross-sections are respectively provided on both sides of the base plate 1. A groove body 102 is provided on the auxiliary reinforcing ribs 101, and mounting holes 103 are provided on the end walls of the groove body 102. When the base plate 1 is installed on the vehicle body, the auxiliary reinforcing ribs 101 are firmly in contact with the mounting surface.

[0060] Insert the bolts into the mounting holes 103 and tighten them on the vehicle body to fix the base plate 1, thereby achieving the installation of the entire bracket and the vehicle-mounted radar body 01. When the base plate 1 is installed on the vehicle body, the auxiliary reinforcement ribs 101 are in close contact with the mounting surface of the vehicle body, providing additional support, which can reinforce the installation of the base plate 1 and ensure the overall stability. At the same time, the mounting holes 103 are set at the grooves 102 on the auxiliary reinforcement ribs 101 to provide points for bolt tightening. Furthermore, the auxiliary reinforcement ribs 101 serve as both auxiliary reinforcement supports for the base plate 1 and fastening components for fixing the base plate 1 to the vehicle body, killing two birds with one stone.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
