Technical Field

[0001] The utility model relates to the technical field of hinges, and in particular to a hinge device for a head-mounted display device. Background Art

[0002] Head-mounted display devices are an important part of the integrated vision system of general aircraft, which can provide pilots with flight symbol display, synthetic vision and enhanced vision fusion functions.

[0003] The distance and angle between the glasses of existing head-mounted display devices and the wearer's eyes cannot be adjusted, and different wearers have different facial features, which results in different wearers seeing different clarity of displayed symbols when wearing head-mounted display devices, thus affecting the wearer's observation of information.

[0004] Therefore, it is necessary to provide a hinge device for a head-mounted display device to solve the above problems. Utility Model Content

[0005] The utility model provides a hinge device for a head-mounted display device to solve the problem that the distance and angle between the glasses of the existing head-mounted display device and the wearer's eyes cannot be adjusted, and different wearers have different facial features, resulting in different clarity of displayed symbols seen by different wearers when wearing the head-mounted display device.

[0007] A hinge base, one end of which has a head connector via a first hinge structure; the other end of which is hingedly connected to a glasses connector via a second hinge structure, the head connector being used to connect to a head-mounted display device; and the glasses connector being used to connect to glasses;

[0008] Among them, the first hinge structure and the second hinge structure have the same structure, and the first hinge structure includes: a first hinge shaft, the middle part of the first hinge shaft and the head connecting piece are connected by a key; a limiting component is provided between one end of the first hinge shaft and the mounting hole of the hinge seat to prevent the hinge shaft from rotating, and the other end of the first hinge shaft is connected to the first positioning cap after passing through the positioning hole set on the hinge seat, and an expanded hole that cooperates with the first positioning cap is opened on the side wall of the hinge seat facing the first positioning cap, and the first positioning cap is pushed to drive the hinge shaft to move to disengage the limitation of the hinge shaft on the limiting component.

[0009] Preferably, the positioning cap is threadedly connected to the hinge shaft.

[0010] Preferably, the limiting assembly includes: a gear provided at one end of the hinge shaft, and the gear is meshed with a section of internal teeth provided in the hinge seat mounting hole.

[0011] Preferably, the inner teeth are arranged in the mounting hole close to one end of the head connector.

[0012] Preferably, it also includes a first return spring, which is sleeved on the hinge shaft in the expanded hole, with one end of the first return spring contacting the end of the first positioning cap and the other end of the first return spring contacting the step surface formed by the expanded hole and the positioning hole.

[0013] Preferably, a spline is provided in the middle of the hinge shaft along its axial direction, and a spline sleeve is connected to the end of the head connector, and the spline sleeve and the spline are cooperatively connected.

[0014] The beneficial effects of the utility model are:

[0015] 1. The hinge shaft is rigidly connected to the head structure through the cooperation between the spline on the hinge shaft and the spline sleeve on the head structure. The spring is compressed by pressing the positioning cap, and the hinge shaft moves in the axial pressing direction. At the same time, the gear at one end of the hinge shaft is disengaged from the internal gear of the hinge seat, so that the hinge seat can rotate around the hinge shaft. When the positioning cap is released, the hinge shaft returns to the assembly position in the axial direction under the restoring force of the spring. At this time, the gear at one end of the hinge shaft is engaged with the internal gear of the hinge seat, thereby realizing the limit locking of the relative position of the head structure and the hinge seat. It should be noted that multi-level adjustment of the angle can be achieved by setting the number of teeth of the gear; that is, the present invention can increase the adjustment range of the glasses through the design of two hinged structures on the hinge seat, thereby meeting the needs of different wearers.

[0016] 2. The gear meshing design on the hinge shaft can achieve accurate positioning of the glasses, preventing the distance and angle between the glasses and the wearer's eyes from changing due to turbulence during flight. BRIEF DESCRIPTION OF THE DRAWINGS
