Description
Technical Field
[0001] The utility model belongs to the technical field of new energy vehicle testing, and particularly relates to a suspension testing platform for new energy vehicles. Background Technique
[0002] The four-column hydraulic vibration test bench is one of the main devices of the new energy vehicle suspension testing platform. The four-column hydraulic vibration test bench is a professional testing device, mainly used to simulate and test the performance of products in a vibration environment. It can simulate vibrations of the same frequency based on the collected road condition information to detect the suspension movement under different road conditions. The advantage of this device is that it can continuously repeat vibrations of the same frequency to better adapt to complex road conditions.
[0003] The four-column hydraulic vibration test bench mainly consists of four columns, upper and lower platforms, a hydraulic system, a motor, shock absorbers and other parts. Among them, the four columns play a role in supporting and stabilizing the entire test bench, and the upper and lower platforms are used to place and fix the products to be tested. The hydraulic system generates vibrations through hydraulic cylinders and precisely controls the amplitude and frequency through a control system. The working principle of the four-column hydraulic vibration test bench is mainly to convert hydraulic energy into kinetic energy through the hydraulic system, thereby generating vibrations. By adjusting the pressure and flow rate of the hydraulic system, the amplitude and frequency of the vibrations can be controlled. At the same time, the motor, as an auxiliary power source, can provide additional vibration energy to meet different test requirements.
[0004] When the existing four-column hydraulic vibration test bench conducts suspension tests on new energy vehicles, it is necessary to first drive the new energy vehicle to the surface of the test platform base, and then drive the new energy vehicle so that its four tires are respectively located on the upper surface of the pallet. Then, the hydraulic system generates vibrations through the hydraulic cylinder and conducts tests. Since vibrations will occur during the test, this will cause the new energy vehicle to slide or even fall from the top of the board during the test, resulting in inaccurate test results and even causing danger. Content of the Utility Model
[0005] The purpose of the utility model is to provide a suspension testing platform for new energy vehicles, aiming to solve the problem that vibrations will occur during the existing test process in the prior art, which will cause the new energy vehicle to slide or even fall from the top of the board during the test, resulting in inaccurate test results and even causing danger.
[0006] To achieve the above object, the present utility model provides the following technical solutions: A suspension test platform for a new energy vehicle, comprising a test platform base, a support plate and a protective plate. The upper surface of the test platform base is provided with a support plate, and the upper surface of the test platform base is connected with a protective plate. The upper surface of the support plate is provided with a hinge, and a baffle is connected to the surface of the hinge. An expansion rod is arranged between the baffle and the support plate. A first rotating shaft is connected between the expansion rod and the support plate, and a second rotating shaft is connected between the expansion rod and the baffle.
[0007] To limit the wheels of the new energy vehicle through the baffle, as an optimal choice of a suspension test platform for a new energy vehicle of the present utility model, the baffle forms a rotating structure with the support plate through the hinge.
[0008] To realize the rotation of the baffle, as an optimal choice of a suspension test platform for a new energy vehicle of the present utility model, the expansion rod forms a rotating structure with the support plate through the first rotating shaft, and the expansion rod forms a rotating structure with the baffle through the second rotating shaft.
[0009] As an optimal choice of a suspension test platform for a new energy vehicle of the present utility model, a driving motor is installed in the groove of the test platform base. The output end of the driving motor is connected with a threaded rod. A bearing seat is installed between the end of the threaded rod and the upper surface of the test platform base. An internally threaded cylinder is connected to the surface of the threaded rod. The internally threaded cylinder penetrates and is connected to the inside of a connecting block. A sliding sleeve is connected to the bottom side of the connecting block. A slide rail is connected to the groove of the test platform base near the sliding sleeve. A camera is installed on the upper surface of the connecting block.
[0010] To realize the movement of the camera, as an optimal choice of a suspension test platform for a new energy vehicle of the present utility model, the threaded rod forms a rotating structure with the bearing seat, and the threaded rod forms a threaded connection with the internally threaded cylinder.
[0011] To limit the connecting block during the movement process, as an optimal choice of a suspension test platform for a new energy vehicle of the present utility model, the sliding sleeve forms a sliding connection with the slide rail.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] In the present utility model, when the new energy vehicle is driving on the surface of the test platform base and the four tires are respectively located on the upper surface of the support plate, at this time, the expansion rod can be operated. When the expansion rod operates, it can extend. When the expansion rod extends, it can squeeze the baffle through the second rotating shaft. When the baffle is squeezed, it can rotate around the central axis of the hinge. The rotation of the baffle can limit the tires of the new energy vehicle, so as to avoid the new energy vehicle from sliding or even slipping off the top of the support plate during the test process.
[0014] In this utility model, when the driving motor operates, it can drive the threaded rod to rotate inside the bearing block. Under the limiting action of the sliding sleeve and the sliding rail, when the threaded rod rotates, it can drive the internally threaded cylinder to move horizontally. The horizontal movement of the internally threaded cylinder can drive the connecting block to move horizontally, and the horizontal movement of the connecting block can drive the camera to move horizontally. Thus, it is convenient to observe the bottom of the new energy vehicle during the test process through the camera. BRIEF DESCRIPTION OF THE DRAWINGS
