Telescopic cantilever elastic beam head-mounted mechanism

Abstract

The invention discloses a telescopic cantilever elastic beam head-wearing mechanism which comprises an overhead lifting force adjuster and a supporting seat adjuster, wherein the overhead lifting force adjuster, a cantilever elastic beam and an elastic steel band form a telescopic cantilever; the telescopic cantilever can perpendicularly lift virtual reality glasses or a virtual reality helmet to suspend in front of a wearer; the hanging force can be directly transmitted to triangular pivots at the top of the head and the afterbrain of the wearer through the telescopic cantilever, a nylon flat band and the supporting seat adjuster, so that the pressure on the face, the forehead and the nose bridge of the wearer can be relieved. The virtual reality glasses or the virtual reality helmet can be directly hung by the lifting force of the telescopic cantilever which is reasonable in design and convenient to adjust, and the lifting gravity is directly transmitted to the triangular pivots at the afterbrain of the wearer, so that the pressure on the face, the forehead and the nose bridge of the wearer can be relieved; therefore the wearer can wear the virtual reality glasses or the virtual reality helmet more practically, easily and comfortably.

Description

technical field [0001] The invention relates to the technical field of virtual reality glasses or virtual reality helmets, in particular to a retractable cantilever elastic beam head-mounted mechanism that can be used for virtual reality glasses or virtual reality helmets. Background technique [0002] With the rapid development of virtual reality technology, in addition to the integrated design of virtual reality helmets with display screens and electronic circuits, virtual reality glasses matched with smartphones have also emerged accordingly. Since the weight of the virtual reality glasses and the mobile phone itself can reach more than 400 grams, the head-mounted mechanism of the virtual reality glasses is worn on the person's head and suspended in the air 40 mm in front of the wearer's eyes. Wearing mechanism cable-stayed virtual reality glasses, the resultant force is transmitted to the top of the wearer's head, back of the head, forehead, nose bridge and denomination ...

Problems solved by technology

[0007] (3) The three soft belts adopt the same width. Although the setting positions of the main hanging soft belts are different, the hanging slots of the auxiliary soft belts on both sides are all set on the symmetrical point of the center of the virtual reality glasses plane. Due to the interference of the bandwidth and the root of the ear , the triangular force support point can only be set in the middle of the back of the brain (see figure 1 , 2 ), and this position on the human head is a place that is easy to slip. In order to prevent the soft belt from slipping, it is necessary to increase the tension of the auxiliary soft belt on both sides, and this tension may increase the frontal pressure on the wearer's face again.

[0009] (5) Three soft straps are used as the head-mounted mechanism, and the pre-tightening force is manually adjusted through the live joint, which can be locked with a "Japanese" buckle or nylon adhesive tape. Therefore, it is difficult to accurately control the pre-tightening force And grasp: If it is "tight", people will feel uncomfortable for a short time, and if it is "loose", the virtual reality glasses will slide

These measures seem to improve the comfort of the existing head-mounted mechanism, but they cannot solve the fundamental problem in the structure of the existing head-mounted mechanism.
