[0031] In this embodiment, the intelligent networked vehicle slides onto the maintenance platform 6 via the wheel positioning rod 34 and can be moved to a certain height by lifting the lifting frame 19. On the maintenance platform 6, the pad 15 on the base frame 14 can be controlled to move downward by contracting the piston rod of the lifting push rod 13, so that the wheel can fit between the rotating roller 9 and the auxiliary roller 40. While the wheel is positioned by the positioning wheel 12, the rotation of the rotating roller 9 can provide favorable assistance for the subsequent intelligent networked vehicle to detect vehicle speed, acceleration, wheel positioning, tread pattern, body matching and other data.

[0032] Example 2, refer to Figure 5 , an intelligent diagnosis and positioning device for intelligent connected vehicles based on an OBD interface, a stand 16 is fixedly connected to the top outer wall of a base 1, and a servo guide rail 17 is fixedly connected to the outer wall on one side of the stand 16, a first reducer 18 is fixedly connected to the slider of the servo guide rail 17, and the output shaft of the first reducer 18 is fixedly connected to a connecting frame 19, and binocular cameras 20 and fill lights 21 are fixedly connected to both ends of the outer wall on one side of the connecting frame 19.

[0033] In this embodiment, the servo guide rail 17 drives the connecting frame 2 to rise and fall, so as to control the binocular camera 20 and the fill light 21 to match the body of the intelligent networked vehicle, and the first reducer 18 drives the connecting frame 19 to rotate, so as to adjust the inclination angle of the binocular camera 20 and the fill light 21. With the cooperation of the X-axis push rod 7 and the Y-axis push rod 5, the maintenance platform 6 can also change the inclination angle accordingly, so that the intelligent networked vehicle can be well matched with the binocular camera 20 and the fill light 21, and the intelligent diagnosis of the data such as the speed, acceleration, wheel alignment, tire tread, and body matching of the intelligent networked vehicle is realized. The detection functions are diverse, and the occupied area required for the detection operation is greatly reduced.

[0034] Example 3, refer to Figure 6 , an intelligent diagnosis and positioning device for intelligent networked vehicles based on an OBD interface, a top frame 22 is welded to the top outer wall of a base 1, and a circular track 23 is installed on the bottom outer wall of the top frame 22, a pulley 24 is slidably connected to the inner wall of the circular track 23, and a mounting seat 25 is rotatably connected to the bottom outer wall of the pulley 24, a connecting rod 26 is rotatably connected between the two mounting seats 25, and a positioning head 27 is fixedly connected to the outer wall of one side of the mounting seat 25, an inner screw rod 28 is rotatably connected to one side of the bottom outer wall of the top frame 22, and a second reducer 29 is fixedly connected to the other side of the bottom outer wall of the top frame 22, a pulley group 30 is installed between the second reducer 29 and the inner screw rod 28, a multi-axis robot 31 is installed on the bottom outer wall of the mounting seat 25, and a visual detector 32 is installed on the bottom outer wall of the multi-axis robot 31.

[0035] In this embodiment, above the intelligent connected vehicle, when the inner screw rod 28 is driven to rotate by the second reducer 29, the internal thread of the inner screw rod 28 will drive the positioning head 27 to move, thereby driving the mounting seat 25 on the entire circular track 23 to move, so that the visual inspection instrument 32 at one end of the multi-axis robot 31 can perform circular inspection on the intelligent connected vehicle, replacing manual single-point inspection, avoiding problems such as missed inspection, repeated inspection, and wrong inspection, and further reducing the occupied area required for inspection.

[0036] Reference Figure 1 A smart connected car is placed on the top outer wall of the inspection platform 6, and an OBD control box 33 is fixedly connected to the supporting legs of the top frame 22. The smart connected car and the OBD control box 33 are connected by a signal line, and the OBD control box 33 is connected to the inside of the smart connected car. When various data tests are performed on the smart connected car, the data will be transmitted to the OBD control box 33.

[0037] Reference Figure 1 The top outer wall of the base 1 is fixedly connected with symmetrically distributed wheel positioning rods 34, which define the movement trajectory of the wheels and help the intelligent networked vehicle move to a predetermined position of the maintenance platform 6.

[0038] Reference Figure 2 A bottom plate 35 is provided inside the lifting frame 2, and a cross rod 36 is provided between the bottom plate 35 and the lifting platform 3, and a lifting push rod 37 is hinged between the bottom plate 35 and the axial rod of the cross rod 36. In the lifting frame 2, the lifting push rod 37 pushes the cross rod 36 to change the inclination angle of the cross rod 36, thereby completing the lifting operation of the lifting platform 3.

[0039] Reference Figure 2 The top of the bottom plate 35 and the bottom of the lifting platform 3 are fixedly connected with symmetrically distributed slideways 38, and the cross rod 36 is slidably connected to the inner wall of the slideway 38. When the lifting frame 2 is lifting, the cross rod 36 needs to slide back and forth on the inner wall of the slideway 38, and the overall height adjustment of the lifting frame 2 is achieved by changing the position of the end point of the cross rod 36.

[0040] Reference Figure 3 A connecting column 39 is fixedly connected between the two rotating rollers 9. When the connecting column 39 is connected between the two rotating rollers 9, the servo motor 8 will drive the two rotating rollers 9 to rotate together at the same time.

[0041] Reference Figures 3 to 4The inner wall of the inspection platform 6 is located on one side of the rotating roller 9 and is rotatably connected to the auxiliary roller 40, and the pad 15 is set between the rotating roller 9 and the auxiliary roller 40. The pad 15 needs to be in a position flush with the rotating roller 9 and the auxiliary roller 40 at the beginning. When the four wheels of the smart connected car are moved onto the four pads 15, the pads 15 are moved downward to make the four wheels of the smart connected car fit between the rotating roller 9 and the auxiliary roller 40, thereby facilitating the control of wheel rotation.

[0042] Reference Figure 3 An X-axis hinge seat 41 and a Y-axis hinge seat 42 are arranged inside the hinge seat assembly 4, and the Y-axis hinge seat 42 is rotatably connected to the top outer wall of the X-axis hinge seat 41. With the mutual cooperation of the X-axis hinge seat 41 and the Y-axis hinge seat 42, the inclination angle of the inspection platform 6 can be adjusted by telescoping the piston rods of the X-axis push rod 7 and the Y-axis push rod 5, so as to facilitate the continuous adjustment of the placement angle of the intelligent networked vehicle.

[0043] Reference Figure 6 The size of the positioning head 27 is matched with the size of the internal thread of the inner screw rod 28. The positioning head 27 on a part of the mounting seat 25 will be located on the inner wall of the inner screw rod 28. When the second reducer 29 drives the inner screw rod 28 to rotate, the internal thread of the inner screw rod 28 will drive the positioning head 27 to move, thereby driving the mounting seat 25 on the entire circular track 23 to move, and the visual inspection instrument 32 at one end of the multi-axis robot 31 can be controlled to perform circular inspection on the intelligent connected vehicle.

[0044] Reference Figures 5 to 6 The binocular camera 20 and the fill light 21 are both arranged at one end of the intelligent connected car, and the multi-axis robot 31 is arranged on the top of the intelligent connected car. During operation, it is necessary to control the maintenance platform 6 to rise through the lifting platform 3, so that the intelligent connected car is just located on one side of the binocular camera 20 and the fill light 21, and the intelligent connected car is just at the bottom of the multi-axis robot 31.

[0045] Working principle: The intelligent networked vehicle first slides along the wheel positioning rod 34 on the base 1 to the maintenance platform 6, connects the OBD control box 33 to the interior of the intelligent networked vehicle, and then uses the lifting frame 2 to lift and move to a certain height. On the maintenance platform 6, the piston rod of the lifting push rod 13 can be retracted to control the pad 15 on the base frame 14 to move downward, so that the wheel can fit between the rotating roller 9 and the auxiliary roller 40. After that, the positioning wheel 12 is used to position the wheel while the rotating roller 9 drives the wheel to rotate. In this process, the servo guide rail 17 drives the connecting frame 19 to rise and fall to control the binocular camera 20 and the fill light 21 to match the body of the intelligent networked vehicle, and then the first reducer 18 drives the connecting frame 19 to rotate to adjust the inclination angle of the binocular camera 20 and the fill light 21. In terms of the intelligent networked vehicle, the X-axis push rod 7 and the Y-axis push rod 5 With the cooperation of the two, the inspection platform 6 can also change the tilt angle accordingly, so that the intelligent connected car can achieve a good match with the binocular camera 20 and the fill light 21. Then the binocular camera 20 is used to detect the speed, acceleration, wheel alignment, tire tread and other data of the intelligent connected car. After that, above the intelligent connected car, the inner screw rod 28 is driven to rotate by the second reducer 29, and the internal thread of the inner screw rod 28 will drive the positioning head 27 to move, thereby driving the mounting seat 25 on the entire circular track 23 to move. A multi-axis robot 31 is installed at the bottom of the mounting seat 25, and a visual inspection instrument 32 is provided at one end of the multi-axis robot 31. During the movement of the mounting seat 25, the visual inspection instrument 32 can perform a circular inspection on the intelligent connected car. When various data are detected on the intelligent connected car, the data will be transmitted to the OBD control box 33.
