Description

Technical Field

[0001] This utility model relates to the field of dynamic detection technology, and in particular to a dynamic detection device for an automobile chassis suspension system. Background Technology

[0002] This utility model relates to the field of dynamic testing technology, and in particular to a dynamic testing device for an automotive chassis suspension system. This device is mainly used in automotive repair, automotive manufacturing, and automotive performance testing, aiming to perform accurate and comprehensive dynamic testing of the working status of the automotive chassis suspension system to ensure the safety, comfort, and stability of the vehicle during driving.

[0003] As a key component of automobiles, the chassis suspension system directly affects the vehicle's driving performance and ride comfort. However, with the continuous development of automotive technology and the increasing complexity of the usage environment, the testing requirements for the chassis suspension system are also becoming higher and higher. Some existing testing methods and devices have many shortcomings.

[0004] The existing technology has the following shortcomings:

[0005] 1) Most testing devices struggle to effectively simulate the complex operating conditions faced by a vehicle's chassis and suspension system during actual driving. For example, in real-world driving, vehicles experience acceleration, deceleration, turning, and traversing different road conditions (such as potholes and speed bumps). Under these conditions, the forces and motion states experienced by the chassis and suspension system are complex and diverse. However, existing technologies often only perform simple static or limited dynamic simulations, such as simulating forces in a single direction or simple vertical vibrations, failing to cover combinations of various operating conditions. This results in significant discrepancies between test results and actual usage.

[0006] 2) When testing key parameters of the chassis suspension system, such as the damping force change of the shock absorber, the stiffness performance of the spring under different forces, and the actual displacement and stress of the suspension components, existing equipment cannot accurately measure these parameters due to the limitations of its structural design and working principle. For example, the transmission components of some devices have low precision, which will produce large errors in the process of transmitting power and motion, so that the force and motion state finally applied to the suspension system do not match the preset value, thus affecting the accurate judgment of the suspension system performance. Utility Model Content

[0007] The motor drives the transmission rod and the rotating disk, and through the rotating shaft, limit block and other structures, the power is accurately transmitted and converted into different forms of motion. Finally, the pressing plate performs dynamic pressing tests on the chassis suspension system to simulate actual working conditions, so as to solve the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A dynamic testing device structure for an automobile chassis suspension system includes a support leg, a first support frame fixedly connected to the top of the support leg, a support plate fixedly connected to the outer surface of the first support frame, a motor fixedly connected to the top of the support plate, a second support frame fixedly connected to the bottom of the support plate, two sliding columns fixedly connected to the bottom of the second support frame, a first transmission rod fixedly connected to the output end of the motor, and a rotating disk fixedly connected to the bottom of the first transmission rod.

[0009] Preferably, a limit block is rotatably connected to the top of the rotating disk, and a rotating shaft is movably inserted inside the rotating disk.

[0010] Preferably, the top of the rotating shaft and the bottom of the limiting block are fixedly connected.

[0011] Preferably, the bottom of the rotating shaft is rotatably connected to a second transmission rod.

[0012] Preferably, one end of the second transmission rod is fixedly connected to a first rotating block.

[0013] Preferably, a sliding plate is rotatably connected to the opposite side of the first rotating block, and a second rotating block is rotatably connected to the top of the sliding plate via a shaft.

[0014] Preferably, a third rotating block is fixedly connected to the bottom of the second rotating block, and a plurality of extension columns are fixedly connected to the bottom of the third rotating block, with a pressing plate fixedly connected to the bottom of each extension column.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the device uses a motor to drive a transmission rod and a rotating disk to work together, converting the motor's rotational motion into complex movements such as the up-and-down, left-and-right swinging and tilting of the pressing plate. This comprehensively simulates the acceleration, deceleration, turning, and driving over potholes or speed bumps faced by the chassis suspension system during vehicle operation, allowing for more accurate detection of its performance and potential problems. By adjusting the motor speed, rotating disk size, transmission rod length, and the positions of the rotating block and sliding plate, the motion parameters can be flexibly adjusted to quickly adapt to different vehicle chassis suspension systems and testing needs. Existing equipment lacks this flexibility and adjustability.

[0017] 2. In this utility model, multiple working conditions can be simulated quickly: The device can quickly switch between different simulated working conditions. Through the speed regulation of the motor and the coordinated movement of various components, a comprehensive dynamic test of the chassis suspension system can be performed in a short time. This greatly shortens the test time and improves the test efficiency, enabling automobile repair companies and manufacturers to conduct quality tests and fault diagnoses on the chassis suspension system more quickly, promptly identify problems and take corresponding measures, and reduce safety hazards and maintenance costs caused by chassis suspension system failures.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] As attached Figure 1 To the attached Figure 4As shown, this utility model provides a technical solution: a dynamic testing device for an automobile chassis suspension system includes a support leg 1, a first support frame 11 fixedly connected to the top of the support leg 1, a support plate 12 fixedly connected to the outer surface of the first support frame 11, a motor 2 fixedly connected to the top of the support plate 12, a second support frame 13 fixedly connected to the bottom of the support plate 12, two sliding columns 23 fixedly connected to the bottom of the second support frame 13, a first transmission rod 22 fixedly connected to the output end of the motor 2, and a rotating disk 33 fixedly connected to the bottom of the first transmission rod 22, providing a stable support foundation for the entire device, ensuring that the device will not shake during the testing process, ensuring the accuracy of the test, further enhancing the stability of the upper structure of the device, making the components firmly connected and working together, providing a reliable installation platform for the motor 2, ensuring the smooth operation of the motor 2, avoiding the impact of motor vibration on the testing effect, serving as a power source, providing power for the entire testing device, accurately controlling the movement of rotating components, realizing dynamic testing of the automobile chassis suspension system, further reinforcing the connection between the support plate 12 and the lower components, enhancing the stability of the entire device structure, and providing a stable support foundation for the sliding plate 31. The sliding action provides guidance, making the movement of the sliding plate 31 smoother and more accurate, improving the detection accuracy, and effectively transmitting the rotational power of the motor 2 to the rotating disk 33, ensuring the stability and reliability of power transmission. Driven by the first transmission rod 22, it rotates, providing a foundation for the movement of subsequent components and making the entire detection action smoother.

[0026] like Figure 3 As shown, a limit block 25 is rotatably connected to the top of the rotating disk 33. A rotating shaft 24 is provided at the internal movable end of the rotating disk 33 to limit the position of the rotating shaft 24, ensuring that the rotating shaft 24 moves along a specific trajectory during the rotation of the rotating disk 33, avoiding deviation, ensuring the accuracy of the detection action, and being able to rotate flexibly within the rotating disk 33. It works in coordination with the rotating disk 33 to convert the circular motion of the rotating disk 33 into its own specific motion form, providing conditions for subsequent transmission.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the rotating shaft 24 and the bottom of the limiting block 25 are fixedly connected. Through the rotational connection, the circular motion of the rotating shaft 24 is effectively converted into the swing motion of the second transmission rod 26, providing a motion form conversion for realizing dynamic pressing detection of the automobile chassis suspension system.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the bottom of the rotating shaft 24 is rotatably connected to the second transmission rod 26. Through the rotatable connection, the circular motion of the rotating shaft 24 is effectively converted into the swing motion of the second transmission rod 26, providing a motion form conversion for realizing dynamic pressure detection of the automobile chassis suspension system.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one end of the second transmission rod 26 is fixedly connected to the first rotating block 27, which transmits the swing motion of the second transmission rod 26 to the sliding plate 31. Through the rotational connection, the sliding plate 31 can move accordingly according to the movement of the second transmission rod 26, thereby realizing the effective connection of the movement between the components.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sliding plate 31 is rotatably connected to the opposite side of the first rotating block 27. The top of the sliding plate 31 is rotatably connected to the second rotating block 28 via a shaft. Under the guidance of the sliding column 23, it slides smoothly up and down in a specific direction, providing a stable foundation for the movement of subsequent components. This ensures that the pressing plate 30 accurately presses and detects the car chassis suspension system, and transmits the up and down movement of the sliding plate 31 to the third rotating block 32 below. The rotational link ensures the flexibility and accuracy of the movement transmission.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a third rotating block 32 is fixedly connected to the bottom of the second rotating block 28, and multiple extension columns 29 are fixedly connected to the bottom of the third rotating block 32. A pressing plate 30 is fixedly connected to the bottom of each extension column 29, which further transmits the motion transmitted by the second rotating block 28 to the extension column 29, ensuring the integrity of the motion transmission chain and transmitting the motion of the third rotating block 32 to the pressing plate 30. The multiple extension columns 29 make the pressing plate 30 more evenly stressed, improving the accuracy and comprehensiveness of the pressing test of the car chassis suspension system. It directly contacts the car chassis suspension system and performs dynamic pressing test by moving up and down. The larger contact area better simulates the actual stress situation and improves the reliability of the test results.

[0032] Working principle: When motor 2 starts, the output end of motor 2 drives the first transmission rod 22 to rotate, which in turn drives the rotating disk 33 to rotate. Since the top of the rotating disk 33 is rotatably connected to the limit block 25, and the top of the rotating shaft 24 is fixedly connected to the bottom of the limit block 25, and the rotating shaft 24 is movably inserted inside the rotating disk 33, the rotation of the rotating disk 33 will drive the limit block 25 and the rotating shaft 24 connected to it to perform circular motion around the center of the rotating disk 33. The bottom of the rotating shaft 24 is rotatably connected to the second transmission rod 26. The circular motion of the rotating shaft 24 is transmitted to the second transmission rod 26, causing one end of the second transmission rod 26 to swing about the bottom of the rotating shaft 24. One end of the second transmission rod 26 is fixedly connected to the first rotating block 27, which swings with the second transmission rod 26. The moving rod 26 swings and moves. A sliding plate 31 is rotatably connected to the opposite side of the first rotating block 27. The movement of the first rotating block 27 causes the sliding plate 31 to slide up and down along the direction of the two sliding columns 23. The top of the sliding plate 31 is rotatably connected to the second rotating block 28 through a shaft. The up and down sliding of the sliding plate 31 causes the second rotating block 28 to move up and down. The bottom of the second rotating block 28 is fixedly connected to the third rotating block 32. The movement of the second rotating block 28 is transmitted to the third rotating block 32. The bottom of the third rotating block 32 is fixedly connected to multiple extension columns 29. The movement of the third rotating block 32 causes the extension columns 29 to move up and down. The bottom of each extension column 29 is fixedly connected to a pressing plate 30, which ultimately allows the pressing plate 30 to move up and down, thereby enabling dynamic pressing tests on the car chassis suspension system.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
