[0002] Advanced Driving Assistance Systems (ADAS) utilize various sensors installed in the vehicle to continuously sense the surrounding environment while driving, collect data, identify, detect, and track static and dynamic objects, and combine this data with navigation map data for system calculations and analysis. This allows the driver to anticipate potential dangers, effectively increasing driving comfort and safety. During vehicle maintenance and repair, it is often necessary to calibrate and recalibrate the sensors of ADAS to ensure its accuracy.

[0003] In related technologies, the LAM01-29 target is often used during the calibration of ADAS systems. The process involves first setting the target holder at a predetermined location near the vehicle, then placing the LAM01-29 target on the holder, and finally making minor horizontal adjustments to the target to begin calibration. However, due to the tall column and long beam of the target holder, its large size makes it difficult to find suitable placement space and transportation inconvenient. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0031] Example:

[0032] Please see Figure 1 This utility model provides an ADAS calibration device, including a calibration bracket and a target 20, with the target 20 mounted on one side of the calibration bracket. In some examples, the target 20 and the calibration bracket are detachably connected.

[0033] Please see Figures 1 to 5 The target 20 has a first connecting structure on one side. The calibration bracket includes a base 1, a column and a crossbeam 3. The column has at least two vertically spaced support pillars 2. Each support pillar 2 is detachably connected to the base 1 through a first disassembly structure. The crossbeam 3 is detachably connected to a support pillar 2 through a second disassembly structure. The base 1 and the crossbeam 3 are located at the two ends of the column, respectively. The column and / or the crossbeam 3 are provided with a second connecting structure, which is used to connect with the first connecting structure.

[0034] The calibration bracket is modularly designed. The column is detachably connected to the base 1 via a first disassembly structure, and the crossbeam 3 is detachably connected to the column via a second disassembly structure. This allows the calibration bracket to be disassembled into the base 1, column, and crossbeam 3. Moreover, the disassembled base 1, column, and crossbeam 3 can be stacked to minimize space usage, or they can be placed separately, offering high placement flexibility. This makes it easy to place in the trunk of a car for convenient transportation and meets the needs of mobile calibration scenarios.

[0035] Please see Figure 4In some embodiments, the pillars 2 are symmetrically distributed on the base 1, and the center of gravity of the base 1 coincides with the center of symmetry of the multiple pillars 2. This allows the base 1 to better support the pillars, ensuring the overall stability of the calibration bracket when placed. For example, when there are two pillars 2, the centers of symmetry of the two pillars 2 coincide with the center of gravity of the base 1. Furthermore, the center of gravity of the crossbeam 3 coincides with the center of symmetry of the multiple pillars 2. This allows the pillars 2 to better support the crossbeam 3, ensuring the overall stability of the calibration bracket when placed.

[0036] Please see Figure 4 In some embodiments, the base 1 is plate-shaped and has an arc-shaped hollow structure, which can form an arc edge on the base 1. In this way, the structure of the base 1 is relatively simple, and the arc edge of the base 1 not only improves the aesthetics, but also reduces weight, saves materials, and reduces production costs.

[0037] Please see Figure 4 and Figure 5 In some embodiments, the base 1 is shaped like a heart, the difference being that its two opposite isosceles sides are straight lines. This design not only resembles a triangle, providing stability and balance for the calibration bracket, but also avoids sharp corners by setting arcs, effectively preventing users from being scratched by the base 1 when carrying the calibration bracket.

[0038] In some embodiments, the thickness of the base 1 ranges from 1mm to 3mm, such as 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.; the multiple between the width of the base 1 and the width of the column ranges from 1 to 1.4, such as 1, 1.1, 1.2, 1.3, 1.4, etc., where the width of the column specifically refers to the sum of the total width of all the supports 2 after assembly and the length of the support beam 7; the multiple between the width of the base 1 and the width of the support 2 ranges from 4 to 8, such as 4, 5, 6, 7, 8, etc.; the multiple between the length of the crossbeam 3 and the length of the support 2 ranges from 1 to 2, such as 1, 1.2, 1.5, 1.8, 2, etc. Thus, the base 1 is relatively thin, making it a thin plate; the width of the base 1 differs significantly from the width of the support column 2, while the length of the crossbeam 3 differs less from the length of the support column 2, which helps maintain balance after the calibration bracket is placed; moreover, the overall volume of the base 1, support column 2, and crossbeam 3 stacked together is small, making it easy to place in the trunk of a car.

[0039] Please see Figure 4 and Figure 5In some embodiments, the first disassembly structure includes a first disassembly component 4, which is mounted on the base 1 and detachably connected to the support column 2; the second disassembly structure includes a second disassembly component 5, which is mounted on the crossbeam 3 and detachably connected to the support column 2. Thus, the first disassembly component 4 enables a detachable connection between the base 1 and the support column, and the second disassembly component 5 enables a detachable connection between the support column and the crossbeam 3.

[0040] In some embodiments, the first disassembly member 4 can be threadedly connected to the support column 2, that is, the first disassembly member 4 can be a screw; the second disassembly member 5 can be threadedly connected to the crossbeam 3, that is, the second disassembly member 5 can be a screw.

[0041] During production, at least two first mounting holes can be provided on the base 1. These first mounting holes facilitate the connection of the first disassembly component 4 to the support column 2. The line connecting the at least two first mounting holes can be substantially parallel to the line connecting the two bottom corners of the base 1, with an error of ±3°. Furthermore, the center of symmetry of the multiple first mounting holes coincides with the center of gravity of the base 1. This allows for better determination of the installation position of the support column 2 on the base 1. The design of the first mounting holes, combined with the design of the base 1 and gravity stability design, further enables the base 1 to better support the column, effectively ensuring overall stability. Similarly, at least two second mounting holes can be provided on the crossbeam 3. These second mounting holes facilitate the connection of the second disassembly component 5 to the support column 2. The second mounting holes are preferably located in the middle of the crossbeam 3, and the center of symmetry of the multiple second mounting holes coincides with the center of gravity of the crossbeam 3. This allows for better determination of the installation position of the support column 2 on the crossbeam 3. Furthermore, the design of the second mounting holes, combined with the design of the crossbeam 3 and gravity stability design, allows the support column 2 to better support the crossbeam 3, ensuring the overall stability of the calibration bracket when placed.

[0042] Please see Figure 1 and Figure 4 In some embodiments, the calibration bracket further includes an adjustment member 10, which is mounted on the base 1 and is used to adjust the horizontal tilt of the column and the crossbeam 3. Thus, the horizontal tilt of the calibration bracket can be adjusted via the adjustment member 10, thereby allowing adjustment of the horizontal tilt of the mounted target 20 during calibration to calibrate the ADAS sensors.

[0043] Depending on actual needs, the adjusting element 10 can be a foot cup.

[0044] Please see Figure 1 and Figure 4 In some embodiments, the base 1 is triangular in shape, and each of the three corners of the base 1 is provided with an adjusting member 10. This allows for easy adjustment of the horizontal tilt of the calibration bracket via the adjusting member 10.

[0045] Specifically, the base 1 can be provided with an adjustable foot cup at each of the two adjacent corners, and a non-adjustable foot cup at the other end, with three adjustable foot cups arranged opposite each other. This way, only two adjustable foot cups need to be adjusted, making the horizontal adjustment more efficient. Moreover, since one of the non-adjustable foot cups is set at one end, the height is fixed, avoiding accidental adjustment of the height of the calibration bracket during the horizontal adjustment process, and effectively ensuring that the calibration height of the target 30 is fixed.

[0046] Please see Figure 1 and Figure 4 In some embodiments, the calibration bracket further includes a support beam 7, with adjacent support columns 2 connected by the support beam 7. A level bubble module 8 is mounted on the support beam 7. Thus, compared to individual, independent support columns 2, the connection of the support beams 7 creates a unified structure, providing greater stability and better supporting large targets 20, such as the LAM01-29 target. Furthermore, the level tilt can be directly observed through the level bubble module 8 during tilt adjustment, resulting in higher accuracy in adjusting the overall tilt of the calibration bracket and target 20.

[0047] In some embodiments, the level bubble module 8 is an instrument component for measuring the level of an object, specifically a closed arc-shaped container filled with a liquid that has good fluidity and strong stability, and the liquid is not completely filled, leaving an air bubble.

[0048] Please see Figure 4 and Figure 5 In some embodiments, the support column 2, crossbeam 3, and support beam 7 are made of aluminum, and all three have recessed slots. This reduces the weight of the support column 2, crossbeam 3, and support beam 7. Furthermore, aluminum profiles have high strength and rigidity, providing strong support stability and effectively preventing the support column 2 from bending, thereby ensuring calibration accuracy.

[0049] Understandably, in order to reduce the weight of the calibration bracket and facilitate transportation, the support column 2, crossbeam 3 and support beam 7 can also be equipped with weight-reducing structures such as graded honeycomb structures or multi-level hollow frames, which can effectively reduce weight without reducing the torsional stiffness of the calibration bracket.

[0050] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, the calibration bracket further includes sliders 6, with two sliders 6 slidably mounted on both ends of the crossbeam 3. The first connection structure includes a first latching part 201 and a second latching part 202 disposed on the target 20. The second connection structure includes a latching member 9 disposed on the support beam 7, with a first latching groove 91 on the latching member 9, which engages with the first latching part 201. The second connection structure also includes a second latching groove 61 disposed on the sliders 6, which engages with the second latching part 202, thereby achieving a detachable connection between the target 20 and the calibration bracket.

[0051] It should be noted that the slider 6, the snap-fit ​​9, and the adjusting part 10 are small in size and light in weight. These parts do not need to be disassembled when the calibration bracket is disassembled. After disassembly, since these parts are still connected to the base 1 or each support 2, the loss of parts can be effectively avoided.

[0052] In some embodiments, the support beam 7 is provided with a storage groove that matches the slider 6. After disassembly, the slider 6 can slide into the storage groove. The base 1 is provided with a positioning groove that matches the support column 2 or the crossbeam 3. After disassembly, the support column 2 or the crossbeam 3 can be embedded into the positioning groove, which not only plays a role in snapping and fixing, but also reduces the overall volume of the calibration bracket.

[0053] Furthermore, compatible magnetic components can be provided between the support beam 7 and the slider 6, and between the base 1 and the column 2 or crossbeam 3. These magnetic components are preferably located inside or near the storage groove and positioning groove, facilitating the magnetic absorption of the slider 6 into the storage groove and the magnetic insertion of the column 2 or crossbeam 3 into the positioning groove, thereby improving the connection's strength and preventing parts from being lost. Of course, to further enhance the connection's strength, compatible snap-fit ​​structures, adhesive structures, or pin structures can also be provided between the support beam 7 and the slider 6, and between the base 1 and the column 2 or crossbeam 3.

[0054] Furthermore, a connected sensor and buzzer can be recessedly installed within the storage slot and / or positioning slot. The sensor can be a miniature pressure sensor, etc., used to detect whether the slider 6, support column 2, or crossbeam 3 is stored in the storage slot or positioning slot. Once the slider 6 is stored in the storage slot and the support column 2 or crossbeam 3 is embedded in the positioning slot, the buzzer can be activated. During transportation, if the slider 6, support column 2, or crossbeam 3 falls off, the buzzer will sound an alarm. When it is necessary to use the assembly calibration bracket, the buzzer should be turned off before assembly can begin.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
