[0010] Preferably, support columns are fixed at the four corners of the bottom surface of the vibration table, and anti-slip pads are fixed at the bottom ends of the support columns.
[0011] Compared with the prior art, a head-up display device vibration test device using the above technical solution has the following beneficial effects:
[0012] 1. When performing a vibration test on the head-up display, the staff will first place the head-up display in the placement slot, and then use the vibration table to drive the vibration plate to vibrate. The vibrating vibration plate will transmit the vibration to the installation folding plate, the placement plate and the head-up display in the placement slot. The head-up display in the placement slot does not contact the pressure sensor when it is installed in place. During the vibration test, the head-up display may contact the pressure sensor in the placement slot due to the large vibration amplitude and generate a force. By observing the frequency of the pressure sensor sensing the pressure, the shockproof performance of the head-up display during the test can be obtained;
[0013] Second, when the equipment on the mounting plate is damaged, the staff can remove and replace the mounting folding plate by unscrewing the first fixing bolt from the first thread groove. In addition, the staff can also remove and replace the fixing plate and the equipment installed on its top surface by unscrewing the second fixing bolt from the second thread groove, thereby increasing the service life of the test equipment during use;
[0014] 3. The vibration table will also transmit vibrations to the ground during the vibration process. During this process, the vibrations generated by the vibration table will be transmitted to the ground through the support columns, and in this process, the anti-slip pad made of rubber will absorb the impact force to prevent the vibration table and the ground from colliding with each other and causing damage, thereby increasing the safety of the vibration table when in use.
