Technical Field

[0001] This application belongs to the field of driver assistance system (ADAS) technology, and more specifically relates to a folding support arm for mounting brackets of vehicle-mounted ADAS equipment and its leveling method. Background Technology

[0002] Advanced Driver-Assistance Systems (ADAS) are a series of systems that utilize advanced technologies such as sensors, cameras, and radar to assist drivers. The primary goal of these systems is to improve driving safety and convenience, thereby effectively reducing traffic accidents.

[0003] The installation requirements for Advanced Driver Assistance Systems (ADAS) are very stringent to ensure the accuracy and reliability of the system. For example, ADAS equipment brackets must be installed on a level surface to ensure the accuracy of sensors and cameras, with a levelness error controlled within ±1°. Furthermore, ADAS equipment brackets must be securely mounted on the vehicle's structural components to prevent loosening or displacement during driving.

[0004] In the field of ADAS equipment bracket technology, folding arms are an important component of vehicle-mounted ADAS equipment mounting brackets. They are used for the installation of vehicle-mounted ADAS equipment. However, in existing folding arm technologies, the folding arms rely solely on buckles and hinges for opening and closing, and there is no structure that can adjust the arms to a horizontal position, making it difficult to meet the requirements for ADAS equipment installation.

[0006] The second objective of this application is to provide a leveling method for a folding support arm of a vehicle-mounted ADAS device mounting bracket. During the adjustment process, the rotational motion of the adjusting component is converted into the pressing force of the force-applying component on the support arm through the linkage of the adjusting component, the rotating component and the force-applying component. The adjustment is fast and precise, meeting the posture requirements of the folding support arm of the vehicle-mounted ADAS device mounting bracket during the installation process.

[0034] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0035] participate Figure 1 and Figure 5 A schematic diagram of an embodiment of a folding support arm 31 for mounting brackets of vehicle-mounted ADAS equipment is disclosed.

[0036] A folding support arm 31 for mounting brackets of automotive ADAS devices includes a positioning main body assembly 10 and a support arm assembly 30. (See also...) Figure 1 The folding support arm 31 generally has a left support arm assembly 301 and a right support arm assembly 302. The left support arm assembly 301 and the right support arm assembly 302 are generally symmetrically arranged and respectively connected to both ends of the positioning main body assembly 10. Both the left support arm assembly 301 and the right support arm assembly 302 can be unfolded relative to the positioning main body assembly 10. Figure 1 In the middle, the left support arm assembly 301 is in a folded state, which is the initial state; the right support arm assembly 302 is in an unfolded state, which is the working state. The working state of the folding support arm 31 is that the folding support arm 31 is unfolded and parallel to the positioning main body assembly 10, which can be used for the installation of vehicle ADAS equipment mounting brackets.

[0037] See Figure 1 For ease of description, both the left support arm assembly 301 and the right support arm assembly 302 will be referred to as support arm assemblies 30 below. The relationship between the positioning main body assembly 10 and one of the support arm assemblies 30 will be described, as well as the adjustment assembly 20 between the positioning main body assembly 10 and one of the support arm assemblies 30.

[0038] A folding support arm 31 for mounting brackets of vehicle-mounted ADAS equipment includes a positioning main assembly 10 and a support arm assembly 30. During operation, the support arm assembly 30 should be adjusted to be parallel to the positioning main assembly 10. Generally, the folding support arm 31 is installed horizontally, meaning the positioning main assembly 10 is mounted on a horizontal platform. In this case, the folding support arm 31 is parallel to the positioning main assembly 10, i.e., the folding support arm 31 is horizontal.

[0039] This application discloses a folding support arm 31 for mounting brackets of vehicle-mounted ADAS equipment, comprising a positioning main assembly 10, a support arm assembly 30, and an adjustment assembly 20. The support arm assembly 30 is connected to the positioning main assembly 10, and the adjustment assembly 20 is used to adjust the support arm assembly 30 to be parallel to the positioning main assembly 10.

[0040] In the folding support arm 31, the positioning main body assembly 10 includes the main frame 11.

[0041] The outrigger assembly 30 includes an outrigger 31, which is disposed at one end of the main frame 11 and is rotatably connected to the main frame 11.

[0042] The adjustment component 20 is used to adjust the support arm 31 to be parallel to the main frame 11.

[0043] The adjustment assembly 20 includes a rotating component 21, a mounting shaft 22, an adjusting component 23, and a force-applying component 24.

[0044] The rotating component 21 includes a first end 211 and a second end 212; the first end 211 is connected to the main frame 11, and the second end 212 is connected to the support arm 31. The rotating component 21 is mounted on the mounting shaft 22 and rotates around the axis of the mounting shaft 22. The adjusting component 23 is used to adjust the rotation angle of the rotating component 21. The force-applying component 24 is driven by the rotating component 21 and acts on the support arm 31. The force-applying component 24 applies different magnitudes of leveling force to the support arm 31 according to different rotation angles of the rotating component 21, and the leveling force adjusts the support arm 31 to be parallel to the main frame 11.

[0045] In this application, the support arm assembly 30 is connected to the positioning main body assembly 10. Specifically, the support arm assembly 30 is rotatably connected to the positioning main body assembly 10, which facilitates the folding and unfolding of the support arm assembly 30.

[0046] In some embodiments, a damping hinge 42 is provided between the outrigger assembly 30 and the positioning body assembly 10, thereby achieving hinged connection between the outrigger assembly 30 and the positioning body assembly 10. Further, see [reference needed]. Figure 2 and Figure 3As shown, a damping hinge 42 connects the main frame 11 and the support arm 31. The support arm 31 is hinged to the main frame 11 via the damping hinge 42, facilitating the folding and unfolding of the support arm 31. It also allows for a movable connection between the support arm 31 and the positioning main frame, enabling the support arm 31 to be adjusted to be parallel to the main frame 11. The damping hinge 42 between the main frame 11 and the support arm 31 ensures that the support arm 31 folds slowly, preventing damage to the support arm assembly 30 due to excessively rapid movement during unfolding or folding.

[0047] In some embodiments, the main frame 11 and the support arm 31 can also be connected by other structural components, with the hinge shaft passing through the main frame 11 and the support arm 31 to achieve the hinge connection between the main frame 11 and the support arm 31.

[0048] In this application, the adjustment component 20 is used to adjust the support arm 31 to be parallel to the main frame 11. Depending on the specific vehicle ADAS device being installed, such as sensors or cameras, the folding support arm 31 may not be installed horizontally; it may be installed at an angle or vertically. Therefore, the adjustment component 20 is used to ensure the support arm 31 is parallel to the main frame 11, guaranteeing the integrity of the folding support arm 31. When the folding support arm 31 needs to be installed horizontally, the main positioning component 10 is first installed horizontally, and then the support arm component 30 is also horizontally aligned with the main positioning component 10. At this point, the adjustment component 20 is used to adjust the support arm 31 to be horizontal. The adjustment component 20 ensures that the folding support arm 31 meets the installation requirements of the vehicle ADAS device mounting bracket, ensuring the performance of the vehicle ADAS device and extending its service life.

[0049] In this application, the rotating component 21 includes a first end 211 and a second end 212; the first end 211 is connected to the main frame 11, and the second end 212 is connected to the support arm 31, which is used to supplement the connection between the support arm 31 and the main frame 11. When the support arm 31 and the main frame 11 are only connected by rotation, it cannot be guaranteed that the support arm 31 will remain parallel to the main frame 11 after adjustment. Therefore, the rotating component 21 is used to connect the main frame 11 and the support arm 31 to ensure that the support arm 31 can remain parallel to the main frame 11 after adjustment, thus ensuring the long-term stability of the ADAS equipment mounting bracket.

[0050] After the positioning main component 10 is installed in a horizontal position, the adjustment component 20 adjusts the support arm 31 to a horizontal position, and the adjustment component 20 can also ensure the horizontal accuracy and long-term stability of the ADAS equipment mounting bracket.

[0051] In this application, the rotating component 21 is connected to the support arm 31. The rotating component 21 is adjusted by the adjusting component 23. The rotating component 21 acts on the force-applying component 24, and the force-applying component 24 adjusts the support arm 31, so that the adjustable support arm 31 is parallel to the main frame 11.

[0052] In this application, the rotating component 21 rotates around the axis of the mounting shaft 22 under the action of the adjusting component 23. The rotation of the rotating component 21 changes the magnitude of the leveling force applied to the support arm 31 by the force-applying component 24, thereby adjusting the support arm 31 until it is parallel to the main frame 11. In this application, the adjustment of the support arm 31 is achieved through the linkage structure of the rotating component 21, the adjusting component 23, and the force-applying component 24. The adjusting component 20 has a reliable structure, is convenient and precise in adjustment, and can also ensure the horizontal accuracy and long-term stability of the ADAS equipment mounting bracket.

[0053] In some embodiments, the rotating member 21 rotates around the axis of the mounting shaft 22 under the action of the adjusting member 23. The rotation of the rotating member 21 changes the magnitude of the leveling force applied to the support arm 31 by the force-applying member 24, thus achieving adjustment of the support arm 31. Therefore, the rotating member 21 here is a lever. The mounting shaft 22 is the fulcrum of the lever, the position of the adjusting member 23 on the lever is the power point, and the position on the lever that acts on the force-applying member 24 is the resistance point. In other words, in this application, the use of a lever cleverly achieves the adjustment of the support arm 31, making the adjustment convenient and precise.

[0054] In some embodiments, see Figure 1 and Figure 2 The force-applying component 24 and the adjusting component 23 are respectively set on both sides of the mounting shaft 22, that is, on the rotating component 21. The mounting shaft 22 is located between the power point and the resistance point. The adjusting component 23 acts on the rotating component 21, and the rotating component 21 rotates around the axis of the mounting shaft 22, changing the magnitude of the leveling force applied by the force-applying component 24 to the support arm 31.

[0055] In some embodiments, the force-applying member 24 and the adjusting member 23 may both be installed on one side of the mounting shaft 22, that is, on the rotating member 21. The resistance point is located between the mounting shaft 22 and the power point, or the power point is located between the resistance point and the mounting shaft 22. The adjusting member 23 acts on the rotating member 21, and the rotating member 21 rotates around the axis of the mounting shaft 22, changing the magnitude of the leveling force applied by the force-applying member 24 to the support arm 31.

[0056] In some embodiments, the rotating member 21 is mounted on the mounting shaft 22 and rotates about the axis of the mounting shaft 22. Alternatively, the rotating member 21 may be fixedly connected to the mounting shaft 22 and rotate together about the axis of the mounting shaft 22. Or, the mounting shaft 22 may be fixedly mounted and the rotating member 21 may be rotatably mounted on the mounting shaft 22 and rotate about the mounting shaft 22.

[0057] In some embodiments, see Figure 2 and Figure 6 A shaft hole 214 is provided on the rotating component 21, and the mounting shaft 22 passes through the shaft hole 214. Then, the mounting shaft 22 is installed with the shaft connection hole 252 on the assembly main frame 25. The mounting shaft 22 can be rotatably installed with the shaft connection hole 252, and the rotating component 21 can be rotatably installed with the mounting shaft 22 or fixedly installed. Alternatively, the mounting shaft 22 can be fixedly installed with the shaft connection hole 252, and the rotating component 21 can be rotatably installed with the mounting shaft 22.

[0058] In some embodiments, see Figure 1 The positioning main component 10 also includes a main frame level 13, which is fixedly installed on the main frame 11 by screws.

[0059] In some embodiments, see Figure 1 The outrigger assembly 30 also includes an outrigger level 32, which is fixed to the outrigger 31 by screws.

[0060] In some embodiments, the adjusting member 23 is a rotating member. The rotating member rotates and moves towards the rotating member 21, adjusting the rotation angle of the rotating member 21; the magnitude of the leveling force is positively correlated with the distance the adjusting member 23 moves towards the rotating member 21. Since the adjusting member 23 is a rotating member, adjusting the support arm 31 involves rotating the adjusting member 23, resulting in simple operation and precise adjustment. The rotating member 23 converts the rotational motion of the rotating member into its movement, which drives the adjusting member 23 to rotate, changing its rotation angle. This rotation angle is then converted into the leveling force of the force-applying member 24. Through the linkage of the rotating member, the rotating member 21, and the force-applying member 24, the adjustment of the support arm 31 is achieved. The adjustment operation is convenient and quick, and using a rotating member as the adjusting operating component allows for high-precision adjustment.

[0061] In this application, the magnitude of the leveling force is positively correlated with the distance the adjusting member 23 moves toward the rotating member 21. That is, when the adjusting member 23 rotates and moves toward the rotating member 21, the greater the distance the adjusting member 23 moves toward the rotating member 21, the greater the leveling force applied by the rotating member 21 to the support arm 31 through the force-applying member 24. Conversely, when the adjusting member 23 rotates and moves, the distance the adjusting member 23 moves toward the rotating member 21 decreases, and the leveling force applied by the rotating member 21 to the support arm 31 through the force-applying member 24 decreases.

[0062] In some embodiments, see Figure 2 and Figure 5 The rotating component is an adjusting screw. Rotating the adjusting screw causes the front end of the adjusting screw to press against and exert a force on the rotating component 21, causing the rotating component 21 to rotate. This changes the leveling force applied to the support arm 31 through the force-applying component 24.

[0063] In some embodiments, the force-applying member 24 is an elastic member. The elastic member is positioned between the rotating member 21 and the support arm 31. The leveling force is the pressing force applied by the elastic member to the support arm 31, and the magnitude of the leveling force is positively correlated with the angle through which the rotating member 21 has rotated. See also... Figure 2 The adjusting member 23 drives the rotating member 21 to rotate around the axis of the mounting shaft 22. The angle between the rotating member 21 and the support arm 31 changes, the elastic member located between the rotating member 21 and the support arm 31 is compressed, the pressing force applied by the elastic member to the support arm 31 changes, and thus the angle of the support arm 31 changes, ultimately making the support arm 31 parallel to the main frame 11.

[0064] The force-applying component 24 is an elastic component with an adjustment operation scheme. The pressure applied by the elastic component to the support arm 31 changes slowly, which can achieve high-precision adjustment of the support arm 31. When the main frame 11 is installed in a horizontal position, the support arm 31 can be precisely adjusted to a horizontal position.

[0065] In some embodiments, the elastic element is a spring, more specifically a helical spring, with its two ends contacting the rotating member 21 and the support arm 31 respectively, converting the rotation of the rotating member 21 into a leveling force applied to the support arm 31. The elastic element can also be a rubber element.

[0066] In this application, the rotation of the adjusting screw is converted into a high-precision horizontal correction of the support arm 31 by adjusting the linkage of the adjusting screw, lever and spring, so as to ensure the installation level accuracy and long-term stability of the ADAS mounting bracket.

[0067] In some embodiments, see figures and Figure 2 The adjusting element 23 and the force-applying element 24 are positioned on opposite sides of the mounting shaft 22 on the rotating element 21. See also... Figure 1 and Figure 2 The force-applying component 24 and the adjusting component 23 are respectively disposed on both sides of the mounting shaft 22, i.e., on the rotating component 21. The mounting shaft 22 is located between the power point and the resistance point on the rotating component 21, which acts as a lever. The adjusting component 23 acts on the rotating component 21, causing the rotating component 21 to rotate around the axis of the mounting shaft 22, thus changing the magnitude of the leveling force applied by the force-applying component 24 to the support arm 31. The positions of the adjusting component 23 and the force-applying component 24 on the rotating component 21, respectively located on both sides of the mounting shaft 22, allow the adjusting component 23 to obtain a larger leveling force with a smaller movement distance, thereby improving the adjustment efficiency and accuracy of the support arm 31.

[0068] In some embodiments, the main frame 11 has a first connecting hole 14 at its end facing the support arm 31, and the support arm 31 has a second connecting hole 34 at its end facing the main frame 11. A mounting shaft 22 is disposed within the second connecting hole 34, and a rotating member 21 is sleeved on the mounting shaft 22, with its second end 212 positioned within the second connecting hole 34. After the support arm 31 is extended, its first end 211 is positioned within the first connecting hole 14.

[0069] The mounting shaft 22 is installed in the second connecting hole 34, and the rotating part 21 is sleeved on the mounting shaft 22, thus realizing the installation of the rotating part 21 on the support arm 31. The second end 212 of the rotating part 21 is placed in the second connecting hole 34, and the first end 211 of the rotating part 21 is placed in the first connecting hole 14, thus realizing the connection between the rotating part 21 and the main frame 11 and the support arm 31.

[0070] The first connecting hole 14 and the second connecting hole 34 provide an installation position for the adjustment component 20, and also facilitate the connection of the adjustment component 20 to the main frame 11 and the support arm 31.

[0071] The rotating part 21 of the adjustment component 20 is placed inside the second connection hole 34 to achieve hidden installation of the rotating part 21 and ensure the integrity of the support arm component 30.

[0072] In some embodiments, a first connecting hole 14 is provided at the end of the main frame 11 facing the support arm 31, and a second connecting hole 34 is provided at the end of the support arm 31 facing the main frame 11. Generally, blind holes are provided at the ends of the support arm 31 and the main frame 11, respectively, serving as the second connecting hole 34 and the first connecting hole 14. Alternatively, the support arm 31 and the main frame 11 themselves may have hollow column holes, serving as the second connecting hole 34 and the first connecting hole 14. The depths of the first connecting hole 14 and the second connecting hole 34 are at least sufficient for the installation of the rotating member 21 and the connection of the rotating member 21 to the main frame 11.

[0073] The mounting shaft 22 is disposed within the second connecting hole 34. The mounting shaft 22 can be installed directly into the second connecting hole 34, or indirectly into the second connecting hole 34. (See reference...) Figure 2 The mounting shaft 22 is mounted on the assembly main frame 25, and the assembly main frame 25 is mounted in the second connecting hole 34, thus realizing the indirect installation of the mounting shaft 22 and the second connecting hole 34, that is, the mounting shaft 22 is installed in the second connecting hole 34.

[0074] In some embodiments, see Figure 2The adjusting member 23 is disposed on the main frame 11 and passes through the main frame 11 and is threadedly connected to the main frame 11. The adjusting member 23 is a rotating member, which is threadedly connected to the main frame 11, that is, the rotating member is screwed into the main frame 11 and partially passes through the main frame 11, and the front end of the rotating member abuts against the rotating member 21 placed in the first connecting hole 14.

[0075] The first end 211 of the rotating component 21 is placed in the first connecting hole 14, realizing the connection between the rotating component 21 and the main frame 11, and thus realizing the connection between the main frame 11 and the support arm 31. The adjusting component 23 is set on the main frame 11, so that the adjusting component 23 is far away from the mounting shaft 22. The working principle of the rotating component 21 is the lever principle, so the adjusting component 23 is set on the main frame 11, which makes it easy for the adjusting component 23 to obtain a large leveling force on the force application component 24 through a very small movement distance of rotation, thereby improving the adjustment accuracy and adjustment efficiency.

[0076] In some embodiments, the adjustment component 20 further includes an assembly main frame 25, which is detachably fixed in the second connection hole 34, and the mounting shaft 22 is installed in the assembly main frame 25, and the force-applying member 24 is placed in the assembly main frame 25.

[0077] See Figure 5 and Figure 7 The structure and outer diameter of the main assembly frame 25 are adapted to the second connecting hole 34, facilitating the installation of the main assembly frame 25 within the second connecting hole 34. A shaft connecting hole 252 is provided on the main assembly frame 25. A mounting shaft 22 is placed inside the main assembly frame 25 and installed in the shaft connecting hole 252. A rotating component 21 is sleeved on the mounting shaft 22 installed on the main assembly frame 25. A force-applying component 24 is installed with the rotating component 21 and is also placed inside the main assembly frame 25. An insertion hole 253 is provided on the main assembly frame 25. The force-applying component 24 is inserted into the main assembly frame 25 through the insertion hole 253 and placed in the storage slot 213 on the rotating component 21. The storage slot 213 accommodates the force-applying component 24. The storage slot 213 and the insertion hole 253 respectively limit the two ends of the force-applying component 24, ensuring that the force-applying component 24 is installed inside the main assembly frame 25. The assembly frame 25 is set up to install the mounting shaft 22, rotating component 21 and force-applying component 24, so as to achieve the integrity or partial integrity of the adjustment component 20, and facilitate the installation of the adjustment component 20.

[0078] During installation, first insert the mounting shaft 22 into the shaft hole 214 on the rotating part 21. Then, insert the mounting shaft 22 and the rotating part 21 together into the main assembly frame 25, and install the mounting shaft 22 into the shaft connection hole 252 on the main assembly frame 25, ensuring that the storage groove 213 on the rotating part 21 faces the insertion hole 253 on the main assembly frame 25. Then, insert the force-applying part 24 into the main assembly frame 25 through the insertion hole 253 and place it in the storage groove 213 on the rotating part 21. Finally, insert the main assembly frame 25 and other components installed on the main assembly frame 25 together into the second connection hole 34, and fix the main assembly frame 25 into the second connection hole 34 with the fixing screw 27, thereby fixing the main assembly frame 25 and the support arm 31.

[0079] The force-applying component 24, which is fixed in the assembly main frame 25 within the second connecting hole 34, will act on the inner wall of the second connecting hole 34 on the support arm 31 through the insertion hole 253 on the assembly main frame 25, thereby enabling the force-applying component 24 to apply a leveling force to the support arm 31.

[0080] The main assembly frame 25 is fixed in the second connecting hole 34 by fixing screw 27, so that the main assembly frame 25 can be detachably fixed in the second connecting hole 34.

[0081] The assembly frame 25 is set up to facilitate the assembly of the adjustment component 20, thereby achieving partial integrity of the adjustment component 20. On the other hand, it facilitates the installation of the adjustment component 20 and ensures its functionality.

[0082] In some embodiments, the adjustment assembly 20 further includes a locking member 26, which fixes the adjustment member 23 and the assembly main frame 25 relative to each other. The locking member 26 passes through the rotating member 21 and is threadedly connected to the rotating member 21. Rotating the locking member 26 causes it to move in the same direction as the adjustment member 23. The locking member 26 also passes through the support arm 31 and the assembly main frame 25, with one end of the locking member 26 located outside the support arm 31 and the other end located inside the assembly main frame 25.

[0083] Rotate locking member 26, and locking member 26 moves forward until the front end of locking member 26 abuts against the inner wall of the main frame 25. At this point, locking member 26 can no longer rotate. After the front end of locking member 26 abuts against the inner wall of the main frame 25, continue to rotate locking member 26. Locking member 26 cannot move forward due to the restriction of the main frame 25. At this point, rotating member 21 should move towards the rear end of locking member 26 under the action of thread force. However, rotating member 21 is restricted by adjusting member 23 threadedly connected to main frame 11 and cannot move towards the rear end of locking member 26. Therefore, rotating member 21 is locked at this point, that is, rotating member 21 is relatively fixed inside the main frame 25. At this point, rotating adjusting member 23 will also prevent rotating member 21 from rotating, that is, rotating member 21 is locked and can no longer be adjusted. After the support arm 31 is adjusted to be parallel to the main frame 11, the rotating member 21 is locked to ensure that the support arm 31 remains parallel to the main frame 11 for a long time.

[0084] See Figure 2 The locking member 26 is disposed between the adjusting member 23 and the mounting shaft 22, and the locking member 26 passes through the support arm 31. In order to avoid over-positioning of the locking member 26, a first clearance groove 33 and a second clearance groove 251 are respectively provided on the support arm 31 and the assembly main frame 25 to allow the locking member 26 to pass through. The rotation of the locking member 26 will not affect the position and movement of the support arm 31 and the assembly main frame 25.

[0085] The locking member 26 passes through the first clearance groove 33 and the second clearance groove 251, and the locking member 26 is threadedly connected to the rotating member 21. When the locking member 26 is pressed, the locking member 26 will drive the rotating member 21 to rotate around the axis of the mounting shaft 22 through the screw connected to the rotating member 21.

[0086] A second cover plate 35 is provided at the end of the support arm 31 facing the main frame 11. The second cover plate 35 covers the end of the second connecting hole 34 to protect the adjustment assembly 20 and prevent accidental disassembly of the adjustment assembly 20. A second through hole 36 is provided on the second cover plate 35, and the first end 211 of the rotating member 21 passes through the second through hole 36.

[0087] In some embodiments, the folding arm 31 for mounting bracket of vehicle ADAS equipment further includes a first connecting component 41, which connects the main frame 11 and the arm 31.

[0088] The first connecting assembly 41 includes a first limiting part 411 fixedly connected to the first end 211 and a second limiting part 412 fixedly on the main frame 11. After the support arm 31 is extended, the first limiting part 411 enters the main frame 11 and connects with the second limiting part 412 and is restricted by the second limiting part 412.

[0089] See Figure 3A first insertion hole 4121 is provided on the second limiting part 412. After the support arm 31 is unfolded, the first limiting part 411 enters the first connecting hole 14 through the first insertion hole 4121 and connects with the second limiting part 412, thereby realizing the connection between the first end 211 and the main frame 11, that is, realizing the connection between the rotating part 21 and the main frame 11, that is, realizing the connection between the support arm 31 and the main frame 11.

[0090] See Figure 3 The first limiting part 411 is a limiting protrusion 4111 provided on the first end 211, and the second limiting part 412 is a first cover plate fixedly installed on the outer end of the first connecting hole 14. The diameter of the first through hole 4121 is smaller than the diameter of the first connecting hole 14. After the first end 211 enters the first connecting hole 14, the limiting protrusion 4111 on the first end 211 passes through the first through hole 4121 and hooks the first cover plate, realizing the connection between the first limiting part 411 and the second limiting part 412, and realizing the connection between the rotating part 21 and the main frame 11. See reference. Figure 2 In the connection between the first limiting part 411 and the second limiting part 412, due to the downward pressing force applied by the force-applying member 24 to the second end 212 of the rotating member 21, the first end 211 of the rotating member 21 rotates upward. At this time, the limiting protrusion 4111 tilts upward and hooks the first cover plate, thereby realizing the connection between the rotating member 21 and the first cover plate, that is, realizing the connection between the rotating member 21 and the main frame 11.

[0091] To ensure that the support arm 31 remains connected to the main frame 11 after deployment, the limiting protrusion 4111 on the rotating component 21 should be high enough to provide sufficient clearance for the adjusting component 23 to apply thrust to the rotating component 21, thus preventing the connection between the support arm 31 and the main frame 11 from failing when the rotating component 21 detaches from the first cover plate during adjustment to a parallel position with the main frame 11. (See reference...) Figure 2 The first limiting part 411 protrudes upward and hooks the second limiting part 412, ensuring that the first limiting part 411 and the second limiting part 412 remain hooked during the process of the adjusting member 23 driving the rotating member 21 to rotate.

[0092] See Figure 3 For the outrigger in its folded position (see attached image), please refer to the image. Figure 2 For the outrigger 31 in its extended position, please refer to [reference needed]. Figure 4The process of unfolding the support arm 31 from the folded state to the unfolded state is as follows: The support arm 31 is manually swung, causing it to rotate around the damping hinge 42. The support arm 31 and the adjusting assembly 20 on it rotate toward the main frame 11. At this time, the rotating component 21 will interfere with the first cover plate. The locking component 26 is manually pressed, pressing the rotating component 21 downwards, causing the first end 211 of the rotating component 21 to rotate downwards, allowing it to pass through the first insertion hole 4121 and enter the first connecting hole 14. Then, the locking component 26 is released, and the first end 211 of the rotating component 21 rotates upwards under the elastic action of the force-applying component 24. The first limiting part 411 on the rotating component 21 enters the first connecting hole 14 and hooks the second limiting part 412, thus completing the unfolding of the support arm 31. The next step is to adjust the support arm 31 to be parallel to the main frame 11.

[0093] Adjust the support arm 31 to be parallel to the main frame 11 and adjust it according to the following process.

[0094] A leveling method for a folding support arm 31 of a vehicle-mounted ADAS device mounting bracket, comprising the following steps: S11. Install the positioning main assembly 10 on the horizontal platform and adjust the positioning main assembly 10 to a horizontal state, then fix the positioning main assembly 10. Fix the main frame 11 on the horizontal platform using the mounting screws 12, and adjust the positioning main assembly 10 to a horizontal state using the main frame level 13 and the mounting screws 12.

[0095] S12. Rotate the support arm assembly 30 to unfold the support arm assembly 30, press the locking member 26, so that the first limiting part 411, which is fixed to the first end 211, enters the main frame 11 and connects with the second limiting part 412. Rotate the support arm assembly 30, and the support arm assembly 30 rotates upward and unfolds with the damping hinge 42 as the fulcrum. During the unfolding of the support arm 31, press the locking member 26 to connect the rotating member 21 with the main frame 11.

[0096] S13. Rotate the adjusting member 23, press the first end 211 on the rotating member 21, the second end 212 on the rotating member 21 rotates around the axis of the mounting shaft 22, the second end 212 squeezes the force applying member 24, the force applying member 24 applies an adjusting force to the support arm assembly 30, the adjusting force is the pressing force applied by the force applying member 24 to the support arm assembly 30, the support arm assembly 30 is in a horizontal state under the action of the pressing force.

[0097] S14. Rotate the locking member 26 so that the end of the locking member 26 located inside the assembly main frame 25 is pressed against the assembly main frame 25, thereby fixing the rotating member 21 relative to the assembly main frame 25.

[0098] During the above leveling process, the rotational motion of the adjusting component 23 is converted into the pressing force of the force-applying component 24 on the support arm 31 through the linkage of the adjusting component 23, the rotating component 21 and the force-applying component 24. The adjustment is fast and precise, which meets the posture requirements of the folding support arm 31 of the vehicle ADAS equipment mounting bracket during the installation process.

Obviously, the specific implementation of this application is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of this application, or the direct application of the inventive concept and technical solution to other occasions without modification, are all within the protection scope of this application.
