Abstract
Description
Technical Field
[0001] This application relates to the field of adjustment equipment technology, and in particular to an adjustment bracket. Background Technology
[0002] In the fields of intelligent transportation and computer vision research, particularly in adversarial example research aimed at improving the safety of autonomous driving systems, a crucial foundational task is to collect large-scale, multi-angle image and video data from the vehicle's perspective in real-world road environments. This data typically includes traffic signs, lane markings, traffic lights, and other road users, and is key to training and testing deep learning models and studying the impact of specific attacks (such as adversarial patches) on vision systems.
[0003] Currently, researchers typically rely on commercially available camera mounts or fixing devices, such as magnetic mounts, clamp mounts, or magnetic mounts, when conducting such vehicle-mounted photography. However, these existing technologies reveal the following significant limitations and shortcomings when applied to specialized intelligent transportation research scenarios:
[0004] 1. Limited adjustment methods and poor flexibility: Most traditional brackets only offer a single degree of freedom for adjustment, such as only being able to change the pitch angle or only being able to rotate horizontally. To obtain a specific, non-standard compound angle (such as simultaneously requiring yaw and pitch), multiple tedious manual attempts and positioning are often required, making it difficult to accurately and quickly locate the target traffic sign, resulting in low work efficiency.
[0005] 2. The adjustment process is cumbersome and requires repeated disassembly and reassembly: Once many brackets are fixed, their spatial position and angle are relatively locked. If it is necessary to change the shooting target or perspective, it is often necessary to remove the entire bracket from the roof, reselect the installation position, and fix and level it. This cycle of "disassembly-movement-reinstallation-recalibration" not only greatly increases the labor intensity and time cost of researchers, but may also make it difficult to guarantee the consistency of the collected data due to slight differences in the installation position.
[0006] 3. Limited fixed location and coverage: The field of view of a single fixed bracket is limited by its mounting point, and the range of angles it can cover in front of the vehicle is very limited. In order to obtain data from different lateral angles in front of the vehicle (such as traffic signs directly in front, to the left front, and to the right front), multiple brackets must be installed at different locations on the roof, which further increases the cost of the equipment and the complexity of deployment.
[0007] Therefore, existing technologies cannot adequately meet the demands of rapid, flexible, accurate, and wide-range multi-angle frontal imaging in intelligent transportation adversarial sample studies. Researchers urgently need a dedicated bracket that can be integrated and installed without repeated disassembly to achieve coordinated adjustment of angle and horizontal position, thereby improving the efficiency and quality of data acquisition. Utility Model Content
[0008] Therefore, it is necessary to provide an adjustment bracket to address the problem that current adjustment brackets cannot achieve coordinated horizontal movement and precise multi-angle adjustment.
[0009] The first aspect of this application provides an adjustment bracket, comprising:
[0010] Base;
[0011] A sliding actuator, used for installing the equipment to be fixed;
[0012] A horizontal adjustment mechanism, disposed on the base, is movably connected to the sliding actuator and is used to drive the sliding actuator to move horizontally; and
[0013] An angle adjustment mechanism is provided, which is connected to the horizontal adjustment mechanism. The angle adjustment mechanism is used to drive the horizontal adjustment mechanism to rotate around its axis, so as to adjust the rotation angle of the sliding actuator provided on the horizontal adjustment mechanism.
[0014] In one embodiment, the angle adjustment mechanism includes:
[0015] A control component is connected to the horizontal adjustment mechanism, and the control component can rotate at a set angle to drive the horizontal adjustment mechanism to rotate synchronously, and the control component can self-lock at any rotation angle.
[0016] In one embodiment, the leveling mechanism includes:
[0017] The tube body has its ends rotatably mounted on the base, and the tube body can rotate synchronously with the control component;
[0018] A guide member is disposed within the tube and is drively connected to the sliding actuator, which is capable of moving horizontally along the path defined by the guide member.
[0019] In one embodiment, the end of the guide member is provided with a limiting member, which is used to restrict the sliding actuator from sliding out of the guide member.
[0020] In one embodiment, the tube body has a slot along its length, and the guide extends horizontally along the length of the tube body and is parallel to the edge of the slot.
[0021] In one embodiment, the leveling mechanism further includes:
[0022] A first transmission gear is disposed within the tube body;
[0023] A transmission component, which meshes with the first transmission gear and is also connected to the sliding actuator in a transmission manner;
[0024] A driving component is connected to the first transmission gear. The driving component is used to drive the first transmission gear to rotate and drive the transmission component to circulate within the tube via the first transmission gear.
[0025] In one embodiment, a receiving cavity is formed between the guide member and the inner wall of the tube body, and the transmission member is partially disposed within the receiving cavity.
[0026] In one embodiment, the sliding actuator includes:
[0027] A connecting pipe is sleeved on the pipe body, and a threaded hole is opened on the pipe wall corresponding to the slot;
[0028] A connector is disposed inside the connecting pipe, and a first mounting position and a second mounting position are respectively provided at both ends of the connector;
[0029] The second transmission gear is sleeved on the connecting member and is simultaneously connected to both the guide member and the transmission member, so that the second transmission gear can move along the transmission member under the drive of the guide member.
[0030] In one embodiment, the sliding actuator further includes:
[0031] A locking element is inserted into the connecting pipe via a threaded hole, and the locking element is connected to the first mounting position;
[0032] The mounting component includes a mounting part and a connecting part. The mounting part is located at one end of the connecting part for mounting the device to be fixed. The other end of the connecting part is inserted into the connecting pipe through another threaded hole and connected to the second mounting position.
[0033] In one embodiment, the base includes a base and an adsorption element, the adsorption element being disposed at the bottom of the base and used to adsorb onto the working surface to fix the base.
[0034] In the aforementioned adjustment bracket, the sliding actuator is used to install the equipment to be fixed. By setting the sliding actuator inside the horizontal adjustment mechanism and integrating the horizontal adjustment mechanism with the angle adjustment mechanism into one unit, the horizontal adjustment mechanism can drive the sliding actuator to move horizontally, and the angle adjustment mechanism can drive the sliding actuator to move rotationally. This achieves horizontal movement adjustment and pitch angle adjustment of the installed equipment, thereby meeting the adjustment needs of a wide range of angles and expanding the applicable scenarios of the equipment.

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0045] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0047] This application provides an adjustable bracket that can be used in the environment of vehicle-mounted equipment, such as for vehicle-mounted shooting, and can also be applied to other scenarios that require horizontal and angle adjustment.
[0048] like Figure 1 As shown in the figure, this application embodiment provides an adjustment bracket, including a base 10, a sliding actuator 20, a horizontal adjustment mechanism 30, and an angle adjustment mechanism 40. The angle adjustment mechanism 40 is directly connected to the base 10, the horizontal adjustment mechanism 30 is connected to the angle adjustment mechanism 40, the sliding actuator 20 is mounted on the horizontal adjustment mechanism 30, and the device to be installed can be mounted on the sliding actuator 20 and move synchronously with it. Thus, the base 10, the sliding actuator 20, the horizontal adjustment mechanism 30, and the angle adjustment mechanism 40 together constitute the adjustment bracket, and through this adjustment bracket, the device mounted on the sliding actuator 20 can be driven to perform horizontal movement adjustment and pitch angle adjustment.
[0049] Specifically, the base 10 includes a base 11 and an adsorption element 12. The base 10 consists of a bottom plate and two side plates, both of which are flat. During installation, the two side plates are vertically mounted on the bottom plate, respectively positioned on opposite sides of the bottom plate, thus forming a U-shaped base 11 together with the side plates. The base 10 serves as the supporting base for the adjustment bracket, and its bottom plate and side plates can be made of materials such as steel, iron, or wood.
[0050] In addition, the adsorption component 12 is located on the side of the base plate away from the side plate. In this embodiment, the adsorption component 12 can be set as a suction cup. The suction cup can be used to adsorb and fix it to the roof or other working surface in a non-invasive manner, thereby realizing the installation and fixation of the base 10.
[0051] like Figure 2 As shown, the angle adjustment mechanism 40 includes a mounting bracket 41 and a control component 42. The base 10 has symmetrically arranged mounting positions on its side plate, allowing the mounting bracket 41 to be installed in one of the two mounting positions. The control component 42 is mounted on one of the mounting brackets 41 and is fixedly connected to the horizontal adjustment mechanism 30.
[0052] In this embodiment, the control element 42 can be configured as a knob, allowing the horizontal adjustment mechanism 30 to rotate synchronously around its central axis by rotating the knob. Additionally, the mounting bracket 41 is an adjustable damping shaft bracket, which provides damping friction to the control element 42. When the control element 42 is rotated to a set angle, the adjustable damping shaft bracket enables the control element 42 to self-lock at any angle; that is, the damping friction output by the adjustable damping shaft bracket to the control element 42 is greater than the force required for the control element 42 to rotate. Therefore, the angle adjustment mechanism 40 does not require an additional locking structure to fix the angle, thus preventing the control element 42 from rotating and stably maintaining the angle rotated by the control element 42 and the horizontal adjustment mechanism 30. It should be noted that the control element 42 can also be configured as a self-damping rotating structure; if this type of structure is used, rotational self-locking can be achieved without a damping shaft bracket.
[0053] like Figure 1 or Figure 2 As shown, the horizontal adjustment mechanism 30 includes a tube 31 and a guide member 32. Both ends of the tube 31 are fixedly connected to a mounting bracket 41 mounted on the side plate. Therefore, when the knob is turned, the mounting bracket 41 rotates synchronously, causing the tube 31 to rotate as well. Furthermore, the guide member 32 is disposed within the tube 31 and is capable of transmission connection with the sliding actuator 20. That is, the sliding actuator 20 can move horizontally along the path defined by the guide member 32.
[0054] Specifically, a limiting member is provided at the end of the guide member 32. The limiting member can be a limiting tooth 321. The limiting tooth 321 can restrict the movable path of the sliding actuator 20 when it moves on the guide member 32, thereby ensuring that the sliding actuator 20 can only move within the range limited by the guide member 32, thus preventing the sliding actuator 20 from falling off the guide member 32.
[0055] More specifically, the edge portion of the tube body 31 is provided with a slot 311, which is opened along the length direction of the tube body 31, and the guide member 32 is disposed inside the tube body 31 and is arranged parallel to the opening direction of the slot 311. In this embodiment, two slots 311 are provided on the tube body 31, and the two slots 311 are symmetrically opened on the tube body 31.
[0056] like Figure 2 As shown, the horizontal adjustment mechanism 30 also includes a first transmission gear 33, a transmission component 34, and a driving component 35. The first transmission gear 33 is disposed inside the tube body 31, and there are two first transmission gears 33, respectively located at both ends of the tube body 31. The two first transmission gears 33 are connected to the tube body 31 via transmission shafts, enabling them to rotate within the tube body 31. The transmission component 34 meshes with both first transmission gears 33 simultaneously, and the second transmission gear 35 is also connected to the sliding actuator 20. The driving component 35 serves as the power transmission component for the first transmission gear 33 and is fixedly connected to it.
[0057] In this embodiment, the driving member 35 is connected to the drive shaft of one of the first transmission gears 33. When the driving member 35 is rocked, the driving member 35 rotates, causing the drive shaft of the first transmission gear 33 to rotate. Simultaneously, the rotation of the drive shaft causes the first transmission gear 33 to rotate. Since both first transmission gears 33 are engaged with the transmission member 34, and the first transmission gears 33 are fixed and connected to the transmission member 34, when the first transmission gear 33 rotates, it drives the transmission member 34 to move from one of the first transmission gears 33 to the other. Then, under the action of the other first transmission gear 33, the second transmission gear 25 rotates back to the initial first transmission gear 33. Thus, through the mutual cooperation between the two first transmission gears 33, the transmission member 34 can perform cyclical motion between the two first transmission gears 33 within the tube body 31.
[0058] Specifically, the transmission component 34 can be configured as an annular rubber rack, which is a closed transmission rack. The first transmission gear 33 can mesh with this closed transmission rack, so that when one of the first transmission gears 33 rotates, the annular rubber rack can be driven to rotate. It should be noted that in this embodiment, two first transmission gears 33 are provided, but in principle, only one first transmission gear 33 is needed to drive the annular rubber rack to perform cyclic motion. Providing two gears further ensures the stability of the annular rubber rack during cyclic motion. In addition, depending on the length of the annular rubber rack, three or four first transmission gears 33 can also be provided to jointly drive the annular rubber rack to move. Thus, through the transmission cooperation between the first transmission gear 33, the second transmission gear 25, the guide component 32, and the transmission component 34, the horizontal movement function can be integrated to achieve precise control of horizontal movement and a compact structure, and improve the overall rigidity and stability of the structure.
[0059] More specifically, to avoid interference between the transmission component 34 and the external environment during cyclic movement, which could affect the normal operation of the cyclic movement, the transmission component 34 can be partially housed within a cavity formed between the guide component 32 and the closed inner wall of the tube body 31. That is, the portion of the tube wall 31 without the slot 311 is designated as a closed tube wall. The end of the guide component 32 facing away from the meshing teeth serves as the bottom surface, and the space between the bottom surface of the guide component 32 and the closed tube wall constitutes the cavity. The cavity is open at both ends, allowing the annular rubber rack to enter from one opening and exit from the other. Thus, by providing a cavity, the transmission component 34 is effectively sealed from external contact, thereby reducing the possibility of interference.
[0060] like Figure 3 and Figure 4 As shown, the sliding actuator 20 includes a connecting pipe 21, a connecting member 22, a locking member 23, and a mounting member 24. The connecting pipe 21 is sleeved on the pipe body 31, and the inner diameter of the connecting pipe 21 is set to be slightly larger than the outer diameter of the pipe body 31, specifically, the inner diameter of the connecting pipe 21 is 2-3 mm larger than the outer diameter of the pipe body 31, to ensure that the connecting pipe 21 can slide smoothly on the pipe body 31. The connecting member 22 is disposed inside the connecting pipe 21, and a first mounting position and a second mounting position are respectively opened at both ends of the connecting member 22. The first mounting position can be connected to the locking member 23, and the second mounting position can be connected to the mounting member 24.
[0061] Specifically, in order to facilitate the installation and fixing of the locking part 23, the mounting part 24 and the connecting part 22, a threaded hole 211 is provided on the wall of the connecting pipe 21, and the threaded hole 211 is provided at the position corresponding to the slot 311.
[0062] In this embodiment, two threaded holes 211 are provided on the wall of the connecting pipe 21, and the two threaded holes 211 are symmetrically arranged. When installing the locking member 23, the locking member 23 is a bolt structure. The bolt is screwed into one of the threaded holes 211 until the bolt is screwed into the first mounting position of the connecting member 22 and forms a connection with the first mounting position to complete the installation and fixation of the locking member 23. Similarly, the mounting member 24 includes a mounting part 241 and a connecting part 242. The mounting part 241 is provided at one end of the connecting part 242 for mounting the device to be fixed. The connecting part 242 is also a bolt structure. The other end of the connecting part 242 is inserted into the connecting pipe 21 through another threaded hole 211 and connects with the second mounting position to achieve a fixed connection of the mounting member 24. Moreover, the connection between the first mounting position and the locking member 23, and the connection between the second mounting position and the mounting member 24 are both threaded connections.
[0063] Specifically, the mounting part 241 can be configured as a universal connecting ball joint, which is capable of rotation. Therefore, when the device to be fixed is connected to the universal connecting ball joint, the device can rotate via the universal connecting ball joint to achieve circumferential angle adjustment. Simultaneously, the mounting part 241 can rotate along the central axis of the tube body 31 under the action of the mounting bracket 41. Combined with the rotation of the mounting part 241, this allows for a wider range of angle adjustments.
[0064] The sliding actuator 20 also includes a second transmission gear 25, which is disposed inside the connecting pipe 21 and simultaneously sleeved on the connecting member 22. The position of the second transmission gear 25 is determined by the position of the connecting member 22. After the second transmission gear 25 is installed, some of the transmission teeth of the second transmission gear 25 mesh with the guide member 32, and some of the transmission teeth of the second transmission gear 25 mesh with the transmission member 34.
[0065] Specifically, the connecting member 22 can be a rolling bearing, and the second transmission gear 25 is sleeved on the outer circumference of the rolling bearing. The inner circumference of the rolling bearing extends axially to both ends to form mounting positions that can connect with the mounting member 24 and the locking member 23. That is, when the second transmission gear 25 is subjected to the force of the transmission member 34, the second transmission gear 25 can drive the outer circumference of the rolling bearing to rotate under the action of the transmission member 34. At this time, the inner circumference of the rolling bearing does not rotate, thereby enabling the second transmission gear 25 to achieve relative rotation with the rolling bearing, so as to ensure that the second transmission gear 25 can move linearly along the guide member 32 under the action of the transmission member 34.
[0066] Furthermore, when the transmission member 34 performs a cyclical motion, it drives the second transmission gear 25 to rotate. When the second transmission gear 25 rotates, it moves along the path defined by the guide member 32. At the same time, the movement of the second transmission gear 25 drives the sliding actuator 20 connected to it to move synchronously. Since the mounting part 241 inside the sliding actuator 20 can be used to install the equipment to be fixed, the second transmission gear 25 can drive the equipment to move synchronously, thereby realizing the horizontal adjustment of the equipment.
[0067] Furthermore, when it is necessary to adjust the pitch angle of the control device, the operator can rotate the control component 42. The rotation of the control component 42 simultaneously rotates the tube body 31. Since the tube body 31 contains the aforementioned sliding actuator 20, its rotation also drives the sliding actuator 20 and the device to be fixed within it to rotate synchronously. Thus, by rotating the control component 42, the rotation angle of the device to be fixed can be adjusted, thereby changing its pitch angle.
[0068] Furthermore, once the set angle is reached, the mounting bracket 41 provides damping friction to achieve self-locking, thus maintaining the rotation angle of the control component 42 without requiring an additional locking structure to fix the rotation angle. Further, the mounting part 241 employs the aforementioned universal ball joint, which is capable of rotation, thereby driving the device mounted on it to rotate synchronously, achieving more angle variations.
[0069] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
