[0002] Vehicle commissioning is a complex process involving multiple steps and elements, which aims to ensure that the various systems of the car can operate normally, achieve the preset performance indicators, and meet relevant standards such as safety and environmental protection. This process is particularly important for the development of new models, but it is also critical for daily maintenance and vehicles in use. The premise of commissioning and maintenance is to align the vehicle before calibration to improve the calibration accuracy. The alignment of the vehicle means aligning the wheels so that the front and rear wheels of the vehicle can cooperate with the rotation of the steering wheel with high precision.

[0003] However, in the prior art, the existing straighteners use hydraulic cylinders or pneumatic cylinders as transmission devices to push the push plates to do work to achieve the purpose of straightening. However, during the pushing process, the front wheels of the vehicle cannot be locked and fixed. Especially when fine-tuning the vehicle, the inability to fix one side alone may lead to uneven force distribution during adjustment, affecting the straightening accuracy. Multiple adjustments may be required to achieve the ideal straightening effect, thereby increasing the operation time. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: it includes a load-bearing plate 1, and the two ends of the top of the load-bearing plate 1 are respectively provided with a stabilizing component 2 and a straightening component 3, and the straightening component 3 is used to realize the straightening effect of the vehicle; the straightening component 3 includes an adapter groove 301 symmetrically opened inside the load-bearing plate 1, and both sides of the inner wall of the adapter groove 301 are symmetrically rotatably connected with a rotating shaft 302, and the rotating shafts 302 are fixedly connected with straightening rollers 303, and the outer periphery of the rotating shaft 302 is fixedly connected with a gear 304 connected by a chain transmission.

[0023] In this embodiment, the front wheels of the car are driven onto the stabilizing assembly 2, and the front wheels will be clamped by the stabilizing assembly 2, ensuring that the front wheels of the car can be accurately aligned to the specified position during the parking process, thereby increasing the stability of the front wheels of the vehicle. At this time, the rear wheels are on the straightening rollers 303, and the gears 304 are driven to rotate through the rotation shaft 302. With the cooperation of the chain, all the straightening rollers 303 are driven to rotate at the same time, driving the rear wheels of the vehicle to move. In this case, the rear wheels of the car can rotate independently of the front wheels, so that the car can move in a direction perpendicular to the original direction of the vehicle. By accurately controlling the steering angle of the rear wheels, the rear part of the vehicle can be moved left and right without changing the direction of the front of the vehicle. The rear wheels of the vehicle can rotate independently of the front wheels, so that the vehicle can move laterally without changing the direction of the front of the vehicle, greatly improving the flexibility of adjusting the position of the vehicle in a narrow space, and achieving the purpose of accurately straightening the position of the vehicle.

[0024] Example 2

[0025] like Figure 1-Figure 4 As shown, a servo motor 4 is fixedly installed on the top of the load-bearing plate 1, and a connecting plate 7 is fixedly connected to the top of the load-bearing plate 1 and located on one side of the servo motor 4. The end of the output end of the servo motor 4 is rotatably connected to one side of the connecting plate 7. The outer peripheries of both ends of the output end of the servo motor 4 are fixedly connected with driving wheels 5, wherein the outer peripheries of the two rotating shafts 302 are fixedly connected with driven wheels 6, and the driving wheels 5 are respectively connected to the corresponding driven wheels 6 through belt transmission. By controlling the operation of the servo motor 4, the driving wheel 5 is driven to rotate, and with the cooperation of the conveyor belt, the driven wheel 6 is driven to rotate, thereby driving the rotating shaft 302 to rotate, and then providing driving force;

[0026] The stabilizing component 2 includes an empty slot 202 symmetrically opened inside the load-bearing plate 1 and located on one side of the adapting slot 301, a triangular block 201 is fixedly connected to the top of the load-bearing plate 1 and located on one side of the empty slot 202, a moving block 209 is slidably connected to the top of the load-bearing plate 1 and located on one side of the triangular block 201, first elastic rollers 206 are equidistantly arranged on the inner sides of the triangular block 201 and the moving block 209, the ends of the first elastic rollers 206 are fixedly connected to connecting plates 207, and second elastic rollers 208 are equidistantly arranged between the two connecting plates 207. When the front wheels of the vehicle drive into the interior of the stabilizing component 2, the vehicle will apply pressure to the first elastic roller 206 and the second elastic roller 208, so that the moving block 209 shrinks inwards and locks the front wheels of the vehicle. The first elastic roller 206 and the second elastic roller 208 can adjust the pressure and position according to the weight of different vehicles, which is convenient for the shrinkage and clamping of the moving block 209, and at the same time can reduce the damage that may be caused by direct contact between the hardware and the wheels;

[0027] A fixed plate 203 is fixedly connected to the top of the load-bearing plate 1 and is located between the triangular block 201 and the moving block 209. A damping column 204 is fixedly connected between one side of the fixed plate 203 and the end of one side of the moving block 209. A spring 205 is sleeved on the outer periphery of the damping column 204. A jack 210 is fixedly connected to the end of one side of the triangular block 201. The piston rod of the jack 210 contacts one side of the moving block 209. A wedge block 8 is symmetrically fixedly connected to the outer side of the load-bearing plate 1. The wedge block 8 facilitates the vehicle to enter the top of the load-bearing plate 1. The spring 205 and the damping column 204 are arranged on the outer periphery of the damping column 204. The damping column 204 plays a guiding and buffering role, so that the moving block 209 always slides in the direction of the damping column 204. At the beginning, the end of the piston rod of the jack 210 is far away from the side of the moving block 209. When the vehicle enters, it will not affect the jack 210. The jack 210 is an existing well-known technology and will not be described here. When the vehicle needs to leave, it only needs to operate the jack 210 so that the piston rod supports the side of the moving block 209 and pushes the moving block 209 to move, so that the front wheels of the car are disengaged from the contraction, which is convenient for the car to leave.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
