Description

Technical Field

[0001] This utility model relates to the field of automotive repair and maintenance technology, specifically to an ADAS calibration equipment universal adjustment unit. Background Technology

[0002] With the development of the automotive industry and the continuous advancement of technology, the degree of automation in automobiles is increasing. Visual and driving control in automobiles, through the detection and recognition processing of various sensors, provides proactive prompts and interventions for the driver, ensuring driving comfort and safety. The various sensors used in ADAS detection mainly include cameras, radar, lasers, and ultrasonic sensors. In the initial stages of automobile production and in situations such as collisions during driving, it is necessary to calibrate various sensors, leading to the development of ADAS calibration equipment. The universal adjustment unit involved in this patent is a key component of the ADAS calibration equipment, used for adjusting the X and Y coordinate positions and the Roll, Yaw, and Pitch angles during ADAS calibration. Existing ADAS calibration equipment generally has two adjustment methods: a simple method is to move the calibration equipment to the required position according to the readings on the measuring scale; the other method is to first move the equipment to an approximate position according to the required calibration values, and then make minor adjustments using mechanisms such as lead screws. Both of these adjustment methods achieve the required position by moving the entire machine, but the accuracy is difficult to control, and the machine is heavy and difficult to move. Fine adjustments are then made through mechanisms such as lead screws, which can meet the accuracy requirements of calibration, but the transmission efficiency of lead screws is low, and multiple dimensions such as X and Y coordinates and Roll, Yaw, and Pitch angles need to be adjusted separately to meet the usage requirements, which is inconvenient and inefficient. Utility Model Content

[0003] To address the aforementioned problems, specifically those raised in the background section, this invention proposes a universal adjustment unit for ADAS calibration equipment. The unit includes a fixed base, with casters and leveling feet installed at the four corners of the lower wall. A locking device is also installed on the lower wall of the fixed base, with rotating handles on both sides of the locking device. A floating base is mounted on the fixed base via a fixed shaft, and a ball bearing is installed between the floating base and the fixed base via a ball bearing retainer. A fixing pin is mounted on the floating base, the fixed base, and the fixed retainer.

[0004] Preferably, the fixing frame is also equipped with a limiting angle.

[0005] Preferably, a level is mounted on the fixed base using level fixing screws.

[0006] Preferably, the locking device is mounted on the bottom surface of the fixed base by locking device fixing screws.

[0007] The beneficial technical effects of this utility model are as follows: The universal adjustment unit described in this patent uses ball bearings as the moving medium, which makes movement convenient and has low resistance. It can simultaneously achieve adjustments in multiple dimensions, including X and Y coordinates, as well as Roll, Yaw, and Pitch angles. It is easy to operate, has high work efficiency, and is widely applicable. Attached Figure Description

[0011] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0012] This utility model proposes a universal adjustment unit for ADAS calibration equipment, including a fixed base 11. Casters 1 and foot cups 2 are installed at the four corners of the lower wall of the fixed base 11. A locking device 4 is also installed on the lower wall of the fixed base 11. Rotating handles 15 are installed on both sides of the locking device. A floating base 12 is installed on the fixed base 11 through a floating base fixing shaft 2. A ball bearing 6 is installed between the floating base 12 and the fixed base 11 through a ball bearing fixing bracket 7. A fixing pin 9 is installed on the floating base 12, the fixed base 11, and the fixing bracket 7. A limit angle is also installed on the fixing bracket 7. A level 14 is installed on the fixed base 11 through a level fixing screw 13.

[0013] Caster 1 is mounted on fixed base 11 by caster fixing screw 5. Foot cup 2 is mounted on fixed base 11. Locking device 4 is mounted on the bottom surface of fixed base 11 by locking device fixing screw 3. Rotary handle 15 is mounted on both sides of locking device 4. Ball bearing 6 is mounted on ball bearing holder 7 and on the upper surface of fixed base 11. The lower surface of floating base 12 rests on ball bearing 6. Floating base 12 is connected to fixed base 11 by floating base fixing shaft 8. Floating base fixing shaft 8 ensures that the connection between fixed base 11 and floating base 12 will not separate, and allows floating base 12 to move in any direction along the upper surface of fixed base 11 as ball bearing 6 rolls, while limiting the range of movement of floating base 12. In the initial position, fixing pin 9 passes through fixed base 11, floating base 12, and ball bearing holder 7. Limiting angle 10 is mounted on ball bearing holder 7. Level 14 is mounted on fixed base 11 by level fixing screw 13. Locking device 4 is mounted on the bottom surface of fixed base 11 by locking device fixing screw 3.

[0014] In the initial position, the fixed pin 9 passes through the fixed base 11, the floating base 12, and the ball bearing retainer 7, and the locking device 4 is in the locked state. Pushing the caster 1 allows the omnidirectional adjustment unit to move as a whole. When ADAS calibration is required, push the caster 1 to move the omnidirectional adjustment unit to a certain distance from the required position. Rotate the foot cups 2 to lift the caster 1 off the ground. Adjust the height of the four foot cups 2 and observe the level 14 to ensure the fixed base 11 is level. Pull the fixed pin 9 out of the fixing hole and push the floating base 12, causing the ball bearings 6 to roll and move the floating base 12 in any direction on the upper plane of the fixed base 11 until it reaches the required coordinate position for calibration. During the movement, ensure the locking device 4 is in the loosened state. After the coordinate position is adjusted, rotate the rotating handles 15 located on both sides of the locking device 4 to lock the omnidirectional adjustment unit. The omnidirectional adjustment unit is now at the required coordinate position for calibration, and ADAS calibration can begin. After calibration, press the rotating handle 15 to release the locking device, move the floating base 12 to return the fixed base 11, floating base 12 and ball bearing retainer 7 to their initial positions, and install the fixed pin 9 back to its original position. During the process of returning to the initial position, the limiting angles 10 installed on both sides of the ball bearing retainer 7 can be pulled to facilitate the ball bearing retainer 7 returning to its initial position.
