Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to an exterior rearview mirror testing system. Background Technology
[0002] Currently, in order to ensure the stability of car rearview mirrors and driving safety, it is necessary to conduct durability tests on the four-axis rotation of car rearview mirrors.
[0003] Traditional testing devices mostly rely on position and angle sensors to test the durability of electric power steering systems in car rearview mirrors. During testing, the rearview mirror is typically stationary on a fixture. This static state only allows for testing the durability of the rearview mirror when the car is not running, and cannot simulate the operation of the electric power steering system due to road bumps while the car is in motion. Consequently, the test data will have some discrepancy with the actual usage data. Furthermore, traditional testing devices, such as those using angle sensors to test the angle of the rearview mirror, generally place the angle sensor directly on the mirror surface without a fixed structure. This makes it easy for the angle sensor to slip off the mirror surface when the rearview mirror angle changes, leading to test failure. Utility Model Content
[0004] The purpose of this invention is to provide an exterior rearview mirror testing system, which has the advantages of accurate testing and anti-slip properties.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an exterior rearview mirror testing system, including a frame, a connecting frame fixedly connected to the top of the frame, a mounting frame provided between the connecting frame and the frame, multiple support springs provided between the mounting frame and the connecting frame and between the mounting frame and the frame, a vibrator provided at the top of the frame, a rearview mirror to be tested provided inside the mounting frame, a rubber disc adsorbed on the top of the mirror surface of the rearview mirror to be tested, a negative pressure seat adhered to the top of the rubber disc, an angle sensor adhered to the top of the negative pressure seat, a negative pressure channel communicating with the rubber disc being opened inside the negative pressure channel, a piston block slidably connected inside the negative pressure channel, and a lead screw threadedly connected to the negative pressure seat being rotatably connected to one side of the piston block.
[0006] The above technical solution is as follows: This utility model incorporates a vibrator on the mounting frame, along with support springs between the mounting frame and the connecting frame, and between the mounting frame and the machine frame. This allows the mounting frame to vibrate between the machine frame and the connecting frame, causing the rearview mirror under test mounted on the mounting frame to vibrate. This simulates the durability of a car rearview mirror under real-time road conditions, improving the accuracy of the test. By mounting the angle sensor on a negative pressure seat, and with a rubber disc installed at the bottom of the negative pressure seat, the negative pressure seat and the rubber disc act like a suction cup, adhering the angle sensor to the mirror surface of the rearview mirror under test. The sensor can move with changes in the angle of the rearview mirror under test without slipping, ensuring the normal operation of the test.
[0007] The present invention is further configured such that an electrical control test box is fixedly connected inside the frame.
[0008] The above technical solution is adopted: the electronic control test box is used to connect the control line of the car rearview mirror and receive the data from the angle sensor. The control system of the electronic control test box measures and feeds back the data to the system through the angle sensor on the surface of the lens. The system controls the four-axis rotation of the rearview mirror motor to carry out durability testing.
[0009] The present invention is further configured such that a fixing hole is provided at the vertical plate of the mounting bracket, and the mounting part of the rearview mirror to be tested is threadedly connected to the fixing hole by bolts.
[0010] The above technical solution is adopted: after the installation part of the rearview mirror to be tested is fixed to the vertical plate of the mounting bracket by bolts and fixing holes, it is convenient to fix the rearview mirror to be tested, so that the vibration of the mounting bracket is transmitted to the rearview mirror to be tested.
[0011] The present invention is further configured such that a vibration sensor is bolted inside the mounting bracket.
[0012] By adopting the above technical solution, the vibration sensor can detect the vibration amplitude of the mounting bracket, allowing staff to adjust the vibration amplitude according to the actual situation.
[0013] The present invention is further configured such that a connecting seat that is bolted to the mounting bracket is fixedly sleeved on the surface of the vibrator.
[0014] The above technical solution facilitates the fixation of the vibrator and prevents the vibrator from separating from the mounting bracket.
[0015] The present invention is further provided that the top and bottom of the mounting bracket and the side of the frame opposite to the connecting bracket are all fixedly connected with sleeves that engage with the support spring.
[0016] The above technical solution facilitates the fixation of the support spring and prevents it from detaching.
[0017] The present invention is further configured such that a rotating handle is fixedly sleeved at the end of the lead screw away from the piston block.
[0018] The above technical solution facilitates the rotation of the lead screw by the operator.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. This utility model has a vibrator designed on the mounting frame. With the support springs between the mounting frame and the connecting frame and between the mounting frame and the machine frame, the mounting frame can vibrate between the machine frame and the connecting frame, so that the rearview mirror under test installed on the mounting frame vibrates, simulating the wear and tear of the car rearview mirror under real-time road conditions, thus improving the accuracy of the test.
[0021] 2. This utility model involves mounting an angle sensor on a negative pressure base, with a rubber disc installed at the bottom of the negative pressure base. The negative pressure base and the rubber disc act like a suction cup, adsorbing the angle sensor onto the mirror surface of the rearview mirror under test. The sensor can change with the angle of the rearview mirror under test without slipping, ensuring the normal progress of the test. Attached Figure Description

The mounting part of the rearview mirror 6 to be tested is threadedly connected to the fixing hole 14 with bolts. By providing the fixing hole 14, once the mounting part of the rearview mirror 6 to be tested is fixed to the vertical plate of the mounting bracket 3 with bolts and fixing holes 14, it facilitates the fixation of the rearview mirror 6 and allows the vibration of the mounting bracket 3 to be transmitted to the rearview mirror 6.
[0029] Brief description of the usage process: By designing a vibrator 5 on the mounting frame 3, when the vibrator 5 is working, it can drive the mounting frame 3 to vibrate between the frame 1 and the connecting frame 2, so that the rearview mirror 6 under test installed on the mounting frame 3 will vibrate, simulating the wear and tear of the car rearview mirror under real-time road conditions, thus improving the accuracy of the test.
[0030] Example 2: Reference Figure 1 , Figure 3 and Figure 4As shown, the exterior rearview mirror testing system includes a frame 1. A connecting frame 2 is fixedly connected to the top of the frame 1. A mounting frame 3 is provided between the connecting frame 2 and the frame 1. Multiple support springs 4 are provided between the mounting frame 3 and the connecting frame 2, and between the mounting frame 3 and the frame 1. A vibrator 5 is provided on the top of the frame 1. The rearview mirror 6 to be tested is provided inside the mounting frame 3. A rubber disc 7 is adsorbed on the top of the mirror surface of the rearview mirror 6. A negative pressure seat 8 is attached to the top of the rubber disc 7. An angle sensor 9 (the angle sensor 9 can be the TLE5501 model sensor from Infineon) is attached to the top of the negative pressure seat 8. A negative pressure channel 10 communicating with the rubber disc 7 is opened inside the negative pressure channel 8. A piston block 11 is slidably connected inside the negative pressure channel 10. A screw 12 threadedly connected to the negative pressure seat 8 is rotatably connected to one side of the piston block 11. A rotating handle 18 is fixedly sleeved at the end of the screw 12 away from the piston block 11. By setting the screw 12, it is convenient for the operator to rotate the screw 12.
[0031] Brief description of the usage process: By installing the angle sensor 9 on the negative pressure base 8, and then the rubber plate 7 installed at the bottom of the negative pressure base 8, the negative pressure base 8 and the rubber plate 7 form a suction cup-like effect, adsorbing the angle sensor 9 onto the mirror surface of the rearview mirror 6 under test. It can change with the angle of the rearview mirror 6 under test without slipping, ensuring the normal progress of the test.
