[0028] Automobile static simulation vibration test is one of the important steps in the current vehicle test, and it is continuously applied to various levels of vehicle models with the development of technology. However, in the test work of vibration tests for multiple types of vehicles, there are a wide variety of automotive shock absorber struts and air springs, with complex structures. Different types and levels of vehicles require different devices, operations, and simulation data during the test, resulting in low overall test efficiency, long test cycles, and being not conducive to use.

[0029] To solve this technical problem, the present utility model proposes a vehicle static simulation vibration test device and a test system. The following will further illustrate the specific structure and functions of the vehicle static simulation vibration test device provided by the embodiments of the present utility model in combination with the text and drawings.

[0030] Referring to Figure 1 and Figure 2 , the vehicle static simulation vibration test device proposed by the present utility model includes a first mounting plate 100 and a second mounting plate 200. The first mounting plate 100 is used to connect to the wheel arch position of the vehicle body, and at least has fixing positions matching the vehicle wheel arch, and is firmly fixed to the vehicle body wheel arch through bolts or clamps. The second mounting plate 200 is used to mount the vehicle's wheel hub and is tightly connected through a special wheel hub clamp or bolts.

[0031] Furthermore, a fixed rod 300 and a movable rod 400 are provided between the first mounting plate 100 and the second mounting plate 200, wherein the movable rod 400 and the fixed rod 300 are telescopically engaged with each other, and the fixed rod 300 is provided with a motor 600 for driving the movement of the movable rod 400. In some embodiments, the movable rod 400 is connected to the first mounting plate 100, the fixed rod 300 is connected to the second mounting plate 200, and the telescopic movement of the motor 600 driving the movable rod 400 is converted into a partial lifting movement of the vehicle body, thereby achieving the purpose of simulating vehicle vibration.

[0032] Specifically, before the test, the first mounting plate 100 is fixed at the vehicle wheel arch, and the second mounting plate 200 is fixed on the wheel hub to ensure the stable installation of the entire test device. The motor 600 is started, and the drive shaft of the motor 600 drives the movable rod 400 to perform telescopic movement along the axial direction in the fixed rod 300, simulating the relative movement between the wheel and the vehicle body under different road conditions. It should be noted that by adjusting the rotation speed and the forward and reverse directions of the motor 600, different vibration frequencies and amplitudes can be simulated to meet different test requirements. Optionally, during the test, auxiliary devices such as sensors can be used to monitor the response of the vehicle suspension system, body structure, etc., and collect relevant data for analysis.

[0033] It should be noted that in some embodiments, the first mounting plate 100 includes various interfaces and adjustment mechanisms to adapt to the installation requirements at the wheel arches of different vehicle models. The first mounting plate 100 is fixedly connected to the vehicle body by means of bolts, clamps, etc., ensuring firm and easy installation. The second mounting plate 200 is also corresponding to the first mounting plate 100 and has the versatility and adaptability to connect with different vehicle model wheel hubs. It is tightly connected to the wheel hub through special clamps, bolts or quick locking devices. While the telescopically engaged fixed rod 300 and movable rod 400 replace the original vehicle shock absorber or air spring, the function of simulating vehicle vibration is realized, and thus the unified test method and steps for different vehicle models in static simulation vibration tests are achieved, greatly simplifying the test process and improving the test efficiency. Moreover, due to the unity of the test method and steps, as well as the high adaptability of the test device, the test cycle of multiple types of vehicles on the same set of test systems is shortened. This not only saves time costs but also reduces the uncertainty and errors during the test.

[0034] On the other hand, compared with the traditional test method that requires customizing test equipment for different vehicle models, the vehicle static simulation vibration test device provided by the present utility model has higher versatility and economy. One set of equipment can meet the test requirements of multiple vehicle models, thereby reducing the test cost.

[0035] Refer to Figure 2Specifically, a connecting portion 500 is provided between the fixing rod 300 and the second mounting plate 200. The connecting portion 500 is an independent metal component and can be made of a high-strength aluminum alloy material to ensure its structural strength and durability. A mounting groove 510 of precise dimensions is machined on the top of the connecting portion 500. The shape of the mounting groove 510 matches the bottom of the fixing rod 300, and the tight connection between the two is ensured through precision machining. At the same time, a fixing plate 520 is provided on the side of the connecting portion 500 for mounting the first mounting plate 100. The fixing plate 520 is located on the side away from the second mounting plate 200, ensuring the compactness of the structure and facilitating the connection between the first mounting plate 100 and the vehicle body. The tight connection between the mounting groove 510 and the fixing rod 300 and the bolt fixation of the fixing plate 520 ensure the stability of the test device during the test.

[0036] Optionally, the inner wall of the mounting groove 510 is provided with anti-slip grooves to increase the friction between the fixing rod 300 and the mounting groove 510 to prevent relative sliding during the test process.

[0037] Specifically, the fixing plate 520 is pre-set with a plurality of mounting holes for fixing the first mounting plate 100 thereon by fasteners. On the other hand, by adjusting the position and number of the mounting holes on the fixing plate 520, the vehicle body structure of different models can be flexibly adapted.

[0038] Reference Figure 2 , a third mounting plate 530 is further extended from the side of the fixing plate 520 of the connecting part 500. The third mounting plate 530 can be made of the same material as the fixing plate 520, and a fixing hole 531 is processed on the third mounting plate 530 according to the installation requirements of the steering gear. The position and size of the fixing hole 531 are precisely calculated and designed to ensure that the steering gear can be firmly mounted on the third mounting plate 530. The third mounting plate 530 enables the test device to support the installation of the steering gear, thereby maximizing the restoration of the original vehicle condition and relevant parameters of the vehicle during driving, thereby meeting the accuracy of the vehicle vibration test data. On the other hand, it can also be combined with the steering test to more comprehensively evaluate the performance of the vehicle under different working conditions.

[0039] Reference Figure 1 and Figure 2, Further, the top and bottom surfaces of the third mounting plate 530 are both arcuately arranged towards the fixing plate 520, forming a first relief arc surface 532 and a second relief arc surface 533, which helps to provide a larger operating space during the installation and disassembly processes and avoid interference with other vehicle components. On the other hand, the third mounting plate 530 to which the first relief arc surface 532 and the second relief arc surface 533 extend is shaped like a handle. When workers install the test device, they can hold the third mounting plate 530 to facilitate the disassembly and assembly of the fixing rod 300 or the wheel hub, thereby simplifying the disassembly and assembly steps of the test device, improving the disassembly and assembly efficiency of the test device, and further enhancing the test efficiency for multiple different types of vehicles.

[0040] Specifically, for vehicles with complex body structures, such as off-road vehicles, the body structures of off-road vehicles are relatively complex and have many protruding and recessed parts. Therefore, special attention needs to be paid to avoiding interference with other body components when installing the test device. By using the connecting part 500 with the first relief arc surface 532 and the second relief arc surface 533, technicians can more smoothly complete the installation work of the test device while reducing the risk of collision with other body components. The increased operating space during the installation and disassembly processes makes the operation smoother and more efficient.

[0041] Further, in some embodiments, the connecting part 500 further includes a third relief arc surface 521, and the bottom surface of the mounting groove 510 facing the fixing plate 520 is also arcuately arranged to form the third relief arc surface 521. It should be noted that the third relief arc surface 521 can further optimize the structure of the mounting groove 510 to ensure that there is enough space below the mounting groove 510 to accommodate the installation of the fixing rod 300. And on the other hand, the third relief arc surface 521, combined with the first relief arc surface 532 and the second relief arc surface 533, increases the local space on the side of the connecting part 500 close to the vehicle body, thereby facilitating workers to install the entire test device and preventing collision with other components.

[0042] Refer to Figure 1A clearance notch 511 is provided on one side of the mounting slot 510 and communicates with the mounting slot 510. The connecting portion 500 is also provided with elastic drive plates 512, located on either side of the clearance notch 511. When the fixing rod 300 needs to be installed or removed, the elastic drive plates 512 can drive the clearance notch 511 to increase, thereby facilitating the insertion or removal of the fixing rod 300. When installing the fixing rod 300, the elastic drive plates 512 are manually or with a tool to move toward each side. As the elastic drive plates 512 move, the clearance notch 511 gradually increases until sufficient space is provided for smooth insertion or removal of the fixing rod 300. Align the fixing rod 300 with the mounting slot 510 and slowly insert it. Once the fixing rod 300 is fully inserted into the mounting slot 510, a locking device (such as a locking screw, a buckle, etc.) is used to secure it in place. After the fixing rod 300 is installed, the elastic drive plates 512 automatically reset to their original state.

[0043] It should be noted that as the external force gradually increases, the elastic drive plate 512 moves along a predetermined trajectory. During this process, the elastic drive plate 512 is gradually stretched or compressed, storing deformation energy. When the elastic drive plate 512 is released and the external force disappears, the elastic drive plate 512 begins to release its stored deformation energy. This energy acts on the elastic drive plate 512 in the form of elastic force, pushing it toward its initial position.

[0044] Furthermore, the fixed rod 300 and the movable rod 400 are both tilted from the first mounting plate 100 toward the second mounting plate 200 to simulate the actual relative positions between the vehicle wheel hub, the shock absorbing strut or the air spring, and the vehicle body, further ensuring the accuracy of the vibration test data.

[0045] Reference Figure 1 In order to prevent interference with the vehicle body or other parts of the chassis, the motor 600 is located on the side of the fixed rod 300 and on the other side away from the second mounting plate 200. Such a layout helps to reduce the impact of the motor 600 on the overall structure of the test device, and is convenient for the installation and maintenance of the motor 600. Furthermore, the drive shaft of the motor 600 is provided with a drive tooth pattern, and the screw rod connected to the movable rod 400 is covered with a drive ring. The drive shaft of the motor 600 is engaged with the drive ring through the drive tooth pattern, thereby driving the screw rod to perform telescopic movement along the axial direction of the fixed rod 300, and the engagement of the drive tooth pattern and the drive ring realizes the precise control and power transmission of the motor 600, and the screw rod and the drive ring make the power transmission more efficient and stable.

[0046] In some other embodiments, the fixed rod 300 is designed to be hollow, with sufficient internal space to accommodate the motor 600, the transmission mechanism, and necessary control components. The motor 600 is firmly mounted on the inner wall of the fixed rod 300 through a bracket or a fixing device. Its output end converts the rotational motion of the motor 600 into the linear motion of the movable rod 400 by means of transmission methods such as a chain, a belt, or a lead screw. For example, a lead screw-nut pair can be used, where the lead screw is driven by the motor 600 to rotate, and the nut is fixed on the movable rod 400, thereby realizing the linear lifting and lowering of the movable rod 400 to ensure its stable operation.

[0047] The present utility model also proposes a vehicle static simulation vibration test system, which includes the vehicle static simulation vibration test device described in any one of the above and a control cabinet. The control cabinet is electrically connected to the motor 600 and is used to control the telescopic direction and speed of the movable rod 400. The control cabinet is provided with a display screen and a panel assembly, and a plurality of electric control buttons are arranged on the panel assembly for the operator to use.

[0048] Optionally, in some embodiments, the control cabinet uses controller devices such as a PLC or a single-chip microcomputer to precisely control the motor 600. The control system issues commands according to input signals (such as button, sensor signals, etc.) to control the start / stop, rotation speed, and rotation direction of the motor 600. And specifically, to meet different operation requirements, the control system supports two modes: manual control and automatic control. In the manual mode, the operator directly controls the movement of the movable rod 400 through control devices such as a handle and buttons; in the automatic mode, the control system automatically completes the movement control of the movable rod 400 according to a preset program.

[0049] Refer to Figure 3 In some embodiments, the control system includes a control cabinet, a motor, a PLC controller, a solenoid valve, etc. The PLC controller is connected to the solenoid valve through a circuit to control the on / off of the positive (negative) pole of its circuit switch. The panel assembly of the control cabinet is connected to the PLC controller. The power supply is connected to both the positive and negative poles of the solenoid valve. The positive and negative poles of the solenoid valve are connected to the forward (reverse) switch. The forward (reverse) switch is connected to the wire harness of the movable rod. The PLC controller is connected to the motor on the fixed rod. The displacement of the movable rod can be controlled by the PLC controller through the forward (reverse) rotation of the motor, and the speed of the movable rod can be adjusted by adjusting the test program.

[0050] Furthermore, the test steps mainly implemented by applying the above vehicle static simulation vibration test system include first driving the test vehicle onto the lift, removing the wheels and shock absorber struts, installing the vehicle static simulation vibration test device, restoring the test vehicle to its original posture, connecting components such as the first mounting plate, the second mounting plate, the fixed rod, and the movable rod, then connecting the circuit, and adjusting the length of the displacement of the movable rod according to the requirements of the test outline. Then download the program, and download the PLC program written according to the test outline into the PLC controller. Then start the power supply, adjust the forward (reverse) switch through the solenoid valve to make the movable rod expand and contract, and conduct the vibration simulation of the test vehicle. After the test is completed, disassemble the vehicle static simulation vibration test device, restore the shock absorber struts of the sample vehicle, install the wheels, and calibrate the torque.

[0051] It should be noted that by formulating a unified test method and steps through the above vehicle static simulation vibration test device, the problem of complex test procedures caused by vehicle type differences is eliminated. This measure ensures that all tested vehicles can follow the same test standards, thereby improving the comparability and consistency of test results. And when it is necessary to test multiple types and levels of vehicles, due to the unity of the test process, the entire test process can be more compact and efficient, thus greatly shortening the total test cycle of multiple types of vehicles.

[0052] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
