Description

Technical Field

[0001] This utility model relates to the field of automotive engineering, and in particular to a shock absorber performance testing device. Background Technology

[0002] Automotive shock absorbers, also known as suspension dampers, are an important component of a vehicle's suspension system. They are primarily used to suppress the vibrations caused by the springs absorbing road impacts and to reduce vehicle body vibration. When a vehicle is driving on uneven roads, the tires are subjected to various impacts and vibrations from the ground. Without shock absorbers, the springs would repeatedly bounce after absorbing these impacts, leading to vehicle instability and significantly reducing driving comfort.

[0003] A testing device for motorcycle shock absorber performance, as disclosed in announcement number CN222671437U, includes a fatigue testing machine and a transmission assembly. This device, through the use of the fatigue testing machine and other structural components, tests the fatigue life and reliability of the motorcycle shock absorber. The transmission assembly drives a connecting rod to test the shock absorber. An installation assembly secures the shock absorber, and an adjustment assembly adjusts the position of the bottom installation assembly to accommodate shock absorbers of different lengths. Multiple threaded holes adjust the position of the push post, thereby adjusting the length of the stretched shock absorber. A connecting ring prevents the rotating disc from tilting during rotation. This device facilitates fatigue testing of shock absorbers of different lengths. However, it cannot simulate different temperatures for testing, making it difficult to accurately reflect actual usage conditions and comprehensively evaluate the shock absorber's performance and reliability. Furthermore, testing the shock absorber in an open space makes it susceptible to external environmental interference, affecting the reliability of the test.

[0004] Therefore, it is necessary to design a shock absorber performance testing device that can simulate different temperatures and adjust different pressures to perform compression tests on the shock absorber, so as to comprehensively evaluate the performance, reliability and durability of the shock absorber and improve the reliability of the test. Utility Model Content

[0005] To overcome the shortcomings of current devices, such as the inability to simulate different temperatures for testing, difficulty in accurately reflecting actual usage conditions, difficulty in comprehensively evaluating the performance and reliability of shock absorbers, and the vulnerability of testing shock absorbers in open spaces to external environmental interference, thus affecting testing reliability, this invention provides a shock absorber performance testing device that can simulate different temperatures and adjust different pressures to perform compression tests on shock absorbers, facilitating a comprehensive evaluation of the performance, reliability, and durability of shock absorbers and improving testing reliability.

[0006] The technical solution is as follows: A shock absorber performance testing device includes a base, a rotating door, an isolation cover, an observation window, a motor, a rotating disk, a circulation pipe, a clamping assembly, and an adjustment assembly. The rotating door is rotatably connected to the left front side of the base, the isolation cover is connected to the upper side of the base, the observation window is slidably connected to the front of the isolation cover, the motor is connected to the rear side of the base, the motor and the processor are electrically connected through a control module, the output shaft of the motor passes through the base and is connected to the rotating disk, the circulation pipe is connected inside the isolation cover, a clamping assembly for clamping the automotive shock absorber is provided between the isolation cover and the base, and an adjustment assembly for adjusting the pressure for testing is provided between the clamping assembly and the base.

[0007] Furthermore, the lower part of the rotating disk has multiple adjustment holes.

[0008] Furthermore, the clamping assembly includes guide rods, a first sliding frame, an electric push rod, and a second sliding frame. Guide rods are connected to the inner sides of both the left and right sides of the isolation cover. The first sliding frame is slidably connected between the lower parts of the guide rods. The first sliding frame is slidably connected to the base. An electric push rod is connected to the upper part of the isolation cover. The electric push rod and the processor are electrically connected through a control module. The second sliding frame is connected to the telescopic end of the electric push rod. All guide rods are slidably connected to the second sliding frame.

[0009] Furthermore, a screw is threaded onto the right side of the middle section of the first sliding frame.

[0010] Furthermore, the adjustment assembly includes a connecting frame, an adjusting plate, a telescopic frame, and a telescopic spring. The connecting frame is rotatably connected to the lower part of the first sliding frame, the adjusting plate is slidably connected to the connecting frame, and the telescopic frame is slidably connected to the lower part of the connecting frame. The telescopic frame is engaged with the rotating disk, the telescopic frame is engaged with the adjusting plate, and a telescopic spring connects the telescopic frame and the connecting frame.

[0011] Furthermore, it also includes inlet and outlet ports, with inlet and outlet ports connected to the upper left and lower right front sides of the circulation pipe.

[0012] The beneficial effects of this utility model are: 1. By pushing the adjustment plate to move, the telescopic frame can be extended and retracted and then fixed to adjust the pressure. Then the shock absorber is installed. The shock absorber is tested by moving the first sliding frame up and down to squeeze it. The temperature is adjusted by entering the circulation pipe with cold or hot medium, thereby simulating different temperatures and adjusting different pressures to squeeze the shock absorber. This facilitates a comprehensive evaluation of the shock absorber's performance, reliability, and durability, and improves the reliability of the test.

[0013] 2. This utility model allows for the opening of the observation window by pulling it open, then placing the car shock absorber on the first sliding bracket. The second sliding bracket is then moved to contact the car shock absorber via an electric push rod. The screw is then turned to move and fix the shock absorber in place. Finally, the observation window is pushed to close the shock absorber. This allows for the fixed testing of the shock absorber in a closed environment, reducing interference, preventing shock absorber displacement, improving the stability and accuracy of the test, and ensuring safe use.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0021] A shock absorber performance testing device, such as Figures 1-5As shown, the device includes a base 1, a rotating door 2, an isolation cover 3, an observation window 4, a motor 5, a rotating disk 6, a circulation pipe 15, inlet and outlet water ports 16, a clamping assembly, and an adjustment assembly. The rotating door 2 is rotatably connected to the front left side of the base 1. The isolation cover 3 is connected to the upper side of the base 1. The observation window 4 is slidably connected to the front part of the isolation cover 3. The motor 5 is connected to the rear side of the base 1. The motor 5 and the processor are electrically connected through a control module. The output shaft of the motor 5 passes through the base 1 and is connected to the rotating disk 6. The rotating disk 6 has three adjustment holes at its lower part for easy adjustment. The circulation pipe 15 is connected inside the isolation cover 3. The inlet and outlet water ports 16 are connected to the upper left and lower right front parts of the circulation pipe 15 to facilitate water inflow and outflow. A clamping assembly for clamping the car shock absorber is provided between the isolation cover 3 and the base 1. An adjustment assembly for adjusting the pressure for detection is provided between the clamping assembly and the base 1.

[0022] like Figures 1-3 As shown, the clamping assembly includes guide rods 7, a first sliding frame 8, an electric push rod 13, and a second sliding frame 14. The guide rods 7 are connected to the inner sides of both the left and right sides of the isolation cover 3. The first sliding frame 8 is slidably connected between the lower parts of the guide rods 7. The first sliding frame 8 is slidably connected to the base 1. A screw is threaded on the right side of the middle part of the first sliding frame 8 for easy fixing. The electric push rod 13 is connected to the upper part of the isolation cover 3. The electric push rod 13 and the processor are electrically connected through a control module. The second sliding frame 14 is connected to the telescopic end of the electric push rod 13. All guide rods 7 are slidably connected to the second sliding frame 14.

[0023] like Figure 3 and Figure 4 As shown, the adjustment assembly includes a connecting frame 9, an adjusting plate 10, a telescopic frame 11, and a telescopic spring 12. The connecting frame 9 is rotatably connected to the lower part of the first sliding frame 8, the adjusting plate 10 is slidably connected to the upper part of the connecting frame 9, and the telescopic frame 11 is slidably connected to the lower part of the connecting frame 9. The telescopic frame 11 is rotatably engaged with the rotating disk 6, and the telescopic frame 11 is engaged with the adjusting plate 10. The telescopic spring 12 connects the telescopic frame 11 and the connecting frame 9.

[0024] This device can be used when performing performance tests on automotive shock absorbers. The base 1 is brought into contact with the ground, and the rotating door 2 is then opened. According to the test requirements, the telescopic frame 11 is pulled to disengage from the rotating disk 6 and the adjusting plate 10, stretching the telescopic spring 12. This pushes the adjusting plate 10, causing the telescopic frame 11 to extend or retract. After reaching the appropriate position, the telescopic frame 11 is released, the telescopic spring 12 rebounds, and the telescopic frame 11 moves in the opposite direction to reset, engaging with the corresponding adjusting holes on the adjusting plate 10 and the rotating disk 6. This allows for adjustment of the adjusting plate 10. The position and length of the telescopic frame 11 are adjusted to control the pressure. After adjustment, the rotating door 2 is closed, and then the observation window 4 is pulled to open. The car shock absorber is then placed on the first sliding frame 8. The processor activates the electric push rod 13 through the control module. The electric push rod 13 drives the second sliding frame 14 to move along the guide rod 7 to contact the car shock absorber. The screw is then turned to move the frame to contact the shock absorber for fixation. The electric push rod 13 is then closed, and the observation window 4 is pushed to close. This allows for shock absorber fixation testing in a closed environment, reducing interference, preventing shock absorber displacement, and improving testing stability. For accuracy and safety, the processor starts the motor 5 via the control module. The motor 5 drives the rotating disk 6 to rotate, which in turn drives the telescopic frame 11 to rotate, causing the connecting frame 9 to rotate. This, in turn, causes the first sliding frame 8 to move up and down to perform a compression test on the shock absorber. Simultaneously, during the test, a cold or hot medium is connected to the inlet / outlet 16 via an external cold or hot medium delivery pipe. This allows the cold or hot medium to enter the circulation pipe 15 and adjust the temperature in the isolation cover 3, thus simulating different temperatures and adjusting different pressures to perform a compression test on the shock absorber. This facilitates a comprehensive evaluation of the shock absorber's performance, reliability, and durability. To improve the reliability of the test, after the test is completed, the motor 5 is turned off, and then the observation window 4 is pulled to open. Then, the screw is rotated to move and disengage from the shock absorber. Then, the electric push rod 13 operates in the opposite direction, causing the second sliding frame 14 to move in the opposite direction and reset. Then, the electric push rod 13 is turned off, and then the observation window 4 is pushed to close. The control method of this embodiment is controlled by a controller. The control circuit of the controller can be easily programmed by those skilled in the art to provide power, which is also common knowledge in the art. Moreover, this article is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
