Description

Technical Field

[0001] The utility model relates to the field of vehicle detection, in particular to a vehicle detection side-slip table. Background Art

[0002] In the field of vehicle detection, the vehicle side-slip inspection bench is a key device for evaluating the side-slip condition of the front wheels of a vehicle. With the continuous development of the automotive industry, the requirements for the accuracy and efficiency of vehicle detection are constantly increasing.

[0003] When the traditional vehicle side-slip inspection bench realizes the function of quickly returning to zero of side-slip, it adopts the method of using a cylinder finger to clamp left and right through air pressure control. However, this method has obvious defects. Firstly, the measuring range of the clamping finger is limited, and in frequent detection operations, it is easy to be damaged due to exceeding the measuring range, increasing the equipment maintenance cost and the risk of detection interruption. Secondly, the clamping force is insufficient. Especially when detecting large vehicles, it is unable to effectively make the side-slip plate quickly return to zero, affecting the detection efficiency and accuracy.

[0004] In order to overcome the above problems, the new vehicle side-slip inspection bench has been innovated in the function of quickly returning to zero of side-slip. It adopts the method of using a pneumatic cylinder to push the side-slip plate to quickly return to its position, and it has significant advantages. Through the control of a single-control solenoid valve, the response speed is fast, and it can quickly push the side-slip plate back to its position. At the same time, the generated force is large enough to meet the detection requirements of various vehicle models, including large vehicles. The way of generating force from one side not only avoids damage caused by range problems but also improves the stability and reliability of the zero-return operation.

[0005] Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a vehicle detection side-slip table to improve the speed of the quick return of the slide plate, with fast response and large force. The way of generating force from one side makes the movement trajectory of the slide plate more stable and predictable, and can ensure that the slide plate can accurately return to the preset initial position each time, thus ensuring the accuracy and repeatability of the detection results.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is: a vehicle detection side-slip table, characterized in that: a frame and a relaxation plate, and the frame and the relaxation plate are connected in cooperation; a link mechanism is arranged on the frame, and a plurality of slide plates are arranged at both ends of the link mechanism, and the slide plates are slidably connected with the frame; the link mechanism is connected with the slide plates on both sides; a cylinder is arranged on one side of the link mechanism and fixedly connected with the frame, and the cylinder is fixedly connected with any one of the slide plates, and the cylinder cooperates with the slide plate to push and pull the slide plate to quickly reset.

[0008] Principle of this solution: The working principle of this vehicle detection skid tester is based on the lateral force exerted by the wheels when the vehicle drives in and the coordinated action of various components. When the vehicle drives into the skid tester, the wheels press on the slidable skateboard. The lateral force during the vehicle's driving causes the skateboard to slide left and right on the frame. The relaxation plate connected to the skateboard can be quickly and accurately reset through the relaxation plate reset mechanism, reducing the detection interval time.

[0009] The rollers at the lower end of the skateboard ensure smooth sliding of the skateboard. The linkage mechanism between the skateboards, under the coordinated action of the swing rod, left connecting rod, and right connecting rod, effectively transmits and disperses the skid force exerted by the vehicle on the skateboard, enabling the two skateboards to move in coordination and accurately reflecting the skid conditions of the vehicle whether it is biased to the left, right, or uneven on both sides.

[0010] The cylinder located on one side of the linkage mechanism makes the movement trajectory of the skateboard stable and predictable by exerting force unilaterally, ensuring that the skateboard accurately returns to the preset initial position. The return spring absorbs and buffers the impact force when the skateboard quickly moves to the limit position or is reset, reducing component collision and wear, and can also assist the skateboard in resetting when the cylinder fails or the pressure is unstable.

[0011] The leveling bolts at the bottom of the frame can fine-tune the frame to ensure that the skid tester reaches a highly precise horizontal state. The displacement sensor is perpendicular to the skateboard and parallel to the cylinder, and can directly and accurately measure the displacement change of the skateboard in the direction perpendicular to the vehicle's driving direction, quickly respond to the movement of the skateboard, and transmit the signal to the detection system for data collection and analysis.

[0012] After the detection is completed, the cylinder starts to push and pull the skateboard to reset. With the assistance of the return spring, the skateboard quickly returns to the initial position, and the relaxation plate also resets accordingly, preparing for the next detection. Thus, the skid amount of the vehicle can be accurately detected, providing a basis for evaluating the vehicle's safety performance.

[0013] The beneficial effects of this solution are as follows: The sliding cooperation between multiple skateboards and the frame can meet the detection requirements of different types and sizes of vehicles, improving the applicable range of the skid tester; the cooperation between the cylinder and the skateboard can achieve rapid reset of the skateboard, reducing the waiting time during the detection process, making the detection process more compact and efficient, and enabling more vehicles to be detected per unit time. The connection between the linkage mechanism and the skateboard and the stable pushing and pulling action of the cylinder help ensure the smoothness and consistency of the skateboard movement during the detection process, thereby improving the reliability of the detection results. By fixedly connecting the cylinder to any one of the skateboards and using the method of exerting force unilaterally, the movement trajectory of the skateboard is made more stable and predictable, ensuring that the skateboard can accurately return to the preset initial position each time, thus guaranteeing the accuracy and repeatability of the detection results.

[0014] Furthermore, the stroke direction of the cylinder is arranged parallel to the sliding direction of the slide plate. This parallel arrangement ensures that the thrust or pull force exerted by the cylinder can act directly and without loss on the slide plate, enabling the slide plate to respond quickly to the actions of the cylinder, improving the response speed and working efficiency of the equipment. It makes the slide plate slide smoothly along the predetermined straight track, thereby ensuring the reliability and consistency of the detection data. At the same time, it reduces the impact and wear on the connecting components and guiding components, extends the service life of the equipment, and reduces the maintenance cost and downtime.

[0015] Furthermore, rollers are provided at the lower end of the slide plate. There are four rollers corresponding to each slide plate, and these rollers are fixedly arranged on the frame and are in rolling fit connection with the slide plate. The four rollers provide stable support and guidance for the slide plate, effectively preventing the slide plate from tilting, shaking or shifting during movement, ensuring that the slide plate always moves in the correct direction, thereby improving the accuracy and reliability of the detection data. The rolling friction of the rollers is much smaller than the traditional sliding friction, enabling the slide plate to move more easily and quickly on the frame, improving the response speed and efficiency of the detection.

[0016] Furthermore, a return spring is provided between the link mechanism and the cylinder. This return spring is connected to the right slide plate and the link mechanism. When the slide plate quickly moves to the limit position or is reset, the return spring can absorb and buffer the impact force, reducing the collision and wear between components and extending the service life of the equipment. In the case of a cylinder failure or unstable pressure, the return spring can still ensure the reset function of the slide plate to a certain extent, improving the fault tolerance and stability of the equipment.

[0017] Furthermore, the slide plate includes a left slide plate and a right slide plate. Guide mechanisms are provided at the lower ends of the slide plate. These guide mechanisms are fixedly arranged to allow the slide plate to slide left and right. The guide mechanisms can strictly limit the movement direction of the slide plate, enabling it to only slide left and right, avoiding deviations in other directions, thereby ensuring the accuracy and reliability of the detection data. The design of sliding left and right can better adapt to the detection requirements of different vehicles. Regardless of the side-slip direction of the vehicle, it can accurately detect and record.

[0018] Furthermore, the link mechanism includes a left link, a right link, a swing rod, and a support seat. The support seat is fixedly arranged on the frame. The center position of the swing rod is connected to the support seat in a mating manner. The left link and the right link are rotatably connected to both ends of the swing rod, and the left link and the right link are respectively connected to the left slide plate and the right slide plate. The side-slip force exerted by the vehicle on the slide plate can be effectively transmitted and dispersed through the links, enabling the left slide plate and the right slide plate to move in coordination and accurately reflect the side-slip situation of the vehicle. At the same time, regardless of whether the side-slip of the vehicle is biased to the left or right, or the side-slip is uneven on both sides, this link mechanism can respond flexibly and measure accurately.

[0019] Furthermore, a relaxation plate reset mechanism is provided at positions near the midline at both ends of the relaxation plate, which can ensure that the relaxation plate resets quickly and accurately. This can reduce the interval time between detections, improve the continuity and efficiency of detections, meet the needs of a large number of vehicle detections, and the stable and reliable reset enables the relaxation plate to return to the standard initial position every time, eliminating the influence of the relaxation plate position deviation on the detection results and improving the accuracy and repeatability of detections.

[0020] Furthermore, a plurality of leveling bolts are provided at the bottom end of the frame. The plurality of leveling bolts can finely adjust the frame at different positions, enabling the side slip table to reach a highly accurate horizontal state, thereby ensuring the accuracy and reliability of detection data. When installing the side slip table, the levelness can be quickly adjusted by simply rotating the leveling bolts, reducing the cumbersome operations and time costs during the installation process. At the same time, after the equipment has been used for a period of time, if there is a deviation in the levelness, it can be conveniently calibrated by adjusting the leveling bolts to ensure that the equipment always maintains a good working state.

[0021] Furthermore, a displacement sensor is provided on one side of the link mechanism. The displacement sensor is arranged in parallel with the cylinder and perpendicular to the slide plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 3 is a schematic structural view of the link mechanism of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The reference numerals in the accompanying drawings of the specification include: frame 1, roller 2, guiding mechanism 3, slide plate 4, left link 5, link mechanism 6, cylinder 7, return spring 8, displacement sensor 9, relaxation plate 10, relaxation plate reset mechanism 11, slide plate limit bolt 12, slide plate fixing bolt 13, leveling bolt 14, support seat 15, swing rod 16, right link 17.

[0026] Example 1 is basically as shown in the attached Figures 1-3As shown: a vehicle detection skid tester, including a frame 1, on which two relaxation plates 10 are provided. The relaxation plates 10 are slidably arranged left and right, and at the central axis positions of both ends of the relaxation plates 10, relaxation plate reset mechanisms 11 are provided, enabling the relaxation plates 10 to ensure rapid and accurate reset, which can reduce the interval time between detections, improve the continuity and efficiency of detections, and meet the needs of a large number of vehicle detections. On the frame 1, two sliding plates 4 are provided. The sliding plates 4 are cooperatively connected with the relaxation plates 10. At the lower ends of the sliding plates 4, four rollers 2 are provided. The rollers 2 are fixedly connected to the frame 1 and are in rolling cooperation with the sliding plates 4, enabling the sliding plates 4 to slide left and right on the rollers 2.

[0027] A link mechanism 6 is provided between the sliding plates 4. The link mechanism 6 includes a left link 5, a right link 17, a swing rod 16, and a support seat 15. The support seat 15 is fixedly arranged on the frame 1. The central position of the swing rod 16 is cooperatively connected to the support seat 15. At both ends of the swing rod 16, the left link 5 and the right link 17 are rotatably connected, and the left link 5 and the right link 17 are respectively connected to the sliding plates 4. The side-slip force applied by the vehicle on the sliding plates 4 can be effectively transmitted and dispersed through the link, enabling the two sliding plates 4 to move in coordination and accurately reflect the side-slip situation of the vehicle. At the same time, whether the side-slip of the vehicle is to the left or right, or the side-slip is uneven on both sides, this link mechanism 6 can flexibly respond and accurately measure. At both ends of the sliding plates 4, sliding plate limit screws 12 and sliding plate fixing screws 13 are provided, effectively restricting the displacement range of the left sliding plate 4 and the right sliding plate 4, and at the same time preventing the left sliding plate 4 and the right sliding plate 4 from falling off.

[0028] A cylinder 7 is arranged on one side of the linkage mechanism 6. The stroke direction of the cylinder 7 is parallel to the sliding direction of the slide plate 4. The cylinder 7 is fixedly connected to one of the slide plates 4 unidirectionally. By applying force unidirectionally, the movement trajectory of the slide plate 4 is more stable and predictable. When applying force unidirectionally, the direction of the force received by the slide plate is clear and fixed. Compared with applying force bilaterally or receiving force in multiple directions, the force in a single direction is easier to control and predict the movement direction of the slide plate, ensuring that the slide plate 4 can accurately return to the preset initial position each time, thus guaranteeing the accuracy and repeatability of the detection results. A return spring 8 is arranged between the linkage mechanism 6 and the cylinder 7. The return spring 8 is connected to the right slide plate 4 and the linkage. When the right slide plate 4 quickly moves to the limit position or is reset, the return spring 8 can absorb and buffer the impact force, reduce the collision and wear between components, and extend the service life of the equipment. In the case of a failure or unstable pressure of the cylinder 7, the return spring 8 can still ensure the reset function of the slide plate 4 to a certain extent. When the slide plate moves under the action of the lateral force of the vehicle, the return spring connected to it will be stretched or compressed. At this time, the return spring stores elastic potential energy. After the detection is completed, when the acting force of the cylinder disappears or weakens, the elastic potential energy stored in the return spring begins to be released, generating a reverse elastic force acting on the slide plate. This elastic force pushes the slide plate towards the initial position, helping the slide plate overcome friction and other resistances, thus realizing the reset. Since the elastic force of the spring is proportional to the deformation of the spring, as long as the deformation of the spring is within its elastic limit, its elastic force can act on the slide plate relatively stably, making it move towards the initial position, thus ensuring the reset function of the slide plate to a certain extent, improving the fault tolerance and stability of the equipment. And a plurality of leveling bolts 14 are arranged at the bottom of the frame 1. The plurality of leveling bolts 14 can finely adjust the frame 1 at different positions, enabling the side slip table to reach a highly accurate horizontal state.

[0029] A displacement sensor 9 is arranged on one side of the linkage mechanism 6. The displacement sensor 9 is arranged parallel to the cylinder 7 and perpendicular to the slide plate 4. The displacement sensor 9 perpendicular to the slide plate 4 can directly measure the displacement change of the slide plate 4 in the direction perpendicular to the vehicle driving direction, accurately reflecting the side slip condition of the vehicle. This vertical measurement method avoids measurement errors caused by angle deviation, ensuring the accuracy of the side slip data. The arrangement parallel to the cylinder 7 enables the displacement sensor 9 to quickly respond to the movement of the slide plate 4. When the vehicle drives into the side slip table or side slip occurs during the detection process, the displacement sensor 9 can quickly capture the displacement change of the slide plate 4 and transmit the signal to the detection system, realizing rapid data acquisition and analysis and improving the detection efficiency.

[0030] When the vehicle drives into the side slip table for detection, the wheels press on the slide plate 4. Due to the action of the lateral force during the vehicle driving process, the slide plate 4 will slide on the frame 1, and the linkage mechanism 6 will move along with the sliding of the slide plate 4, thus transmitting the side slip amount of the wheels.

[0031] After the detection is completed, the cylinder 7 is activated, and the push-pull slide plate 4 quickly resets. With the assistance of the return spring, the slide plate 4 can quickly return to the initial position. At the same time, the relaxation plate reset mechanism 11 also makes the relaxation plate 10 return to the initial state to prepare for the next detection.

[0032] By using the vehicle detection skid tester, the skid amount of the vehicle can be accurately detected, providing an important basis for the safety performance evaluation of the vehicle.

[0033] The above has described the embodiments of the present utility model in detail in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and deformations made to these embodiments still fall within the protection scope of the present utility model.
