Description

Technical Field

[0001] The present invention belongs to the technical field of fatigue testing devices for head mounted display equipment, and in particular relates to a testing device for head mounted display equipment. Background Art

[0002] Head-mounted display devices send optical signals to the eyes through various head displays, which can achieve different effects such as virtual reality (VR), augmented reality (AR), and mixed reality (MR). At present, head-mounted display devices include a shell, a cushion and an audio-visual component. The audio-visual component is installed in the shell to project images and play sounds to the human eyeglasses.

[0003] The cushion of a head-mounted display device has a limit to the number of times it can be pressed. When the number of times it is pressed reaches the limit, the cushioning effect of the cushion will decrease or even be lost. Therefore, it is necessary to design a head-mounted display device testing device to test the cushion during the production process, so as to test the limit of the number of times the cushion can be pressed.

When the buffer pad is damaged, the number of squeezing times is recorded to measure the pressure limit of the buffer pad.

[0055] The second mounting seat 6 is provided with a mounting column 14 for mounting a buffer pad.

[0056] The working principle of the head mounted display device testing device of the embodiment of the present invention is as follows:

[0057] When the buffer pad is tested, the transition plate 8 is driven by the translation mechanism 13 to move to drive the second mounting seat 6 to approach the model 3, and the buffer pad installed on the second mounting seat 6 is squeezed with the model 3. The tension sensor 7 measures the tension between the transition plate 8 and the translation mechanism 13. Since the transition plate 8 is connected to the second mounting seat 6 through the connecting rod 9, the buffer pad is installed on the second mounting seat 6. Therefore, the tension between the transition plate and the translation mechanism 13 measured by the tension sensor 7 is the pressure between the buffer pad and the model 3. The translation mechanism 13 can drive the transition plate 8 according to the set tension value to drive the buffer pad on the second mounting seat 6 to squeeze the model 3, so that the pressure value of each squeezing of the buffer pad and the model 3 is consistent, so as to accurately measure the maximum number of compression limits of the buffer pad.

[0058] During the test, the angle of the second mounting seat 6 can be changed by changing the rotation angle, thereby changing the extrusion angle between the buffer pad and the model 3. The height of the transition plate 8 and the second mounting seat 6 can be changed by changing the height of the second pulling plate 12, thereby changing the extrusion height between the buffer pad and the model 3. This allows the second mounting device to be well adapted to models 3 of different specifications, and the buffer pad to better fit models 3 of different specifications.

[0059] According to the head-mounted display device testing device of an embodiment of the present invention, the tension sensor 7 is arranged between the transition plate 8 and the translation mechanism 13. When the translation mechanism 13 drives the transition plate 8 to move to drive the second mounting seat 6 to approach the model 3, the buffer pad installed on the second mounting seat 6 is squeezed with the model 3, and the tension sensor 7 measures the tension between the transition plate 8 and the translation mechanism 13. Since the transition plate 8 is connected to the second mounting seat 6 through the connecting rod 9, and the buffer pad is installed on the second mounting seat 6, the tension between the transition plate and the translation mechanism 13 measured by the tension sensor 7 is the pressure between the buffer pad and the model 3. The translation mechanism 13 can drive the transition plate 8 according to the set tension value to drive the buffer pad on the second mounting seat 6 to squeeze the model 3, so that the pressure value of each squeezing of the buffer pad and the model 3 is consistent, so as to accurately measure the maximum number of compression limits of the buffer pad.

[0060] In other embodiments, the translation mechanism 13 may be a screw-nut mechanism.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
