Helmet body flexible connecting structure of helmet display

Abstract

The invention relates to a helmet body flexible connecting structure of a helmet display. The helmet body flexible connecting structure of the helmet display is mainly composed of an outer helmet, a display mirror, an inner helmet, a mandible belt, special coupling screws and normal coupling screws; the backside of the helmet body of the helmet display is connected by using normal coupling screws,and two sides are connected by using the special coupling screws; a nut, an optical axis and thread are arranged on each special coupling screw; the optical axis penetrates the outer helmet, the thread is fastened with the inner helmet, and the clearance is formed between the nut and the outer helmet 1; the outer helmet can slide along a screw tightening direction on the special coupling screw optical axis, and cannot move on a vertical screw tightening direction. The connection flexibility of the helmet body of the helmet display is enhanced, when the mandible belt is tightened, the outer helmet slides on the special coupling screw optical axis to counteract the shrinkage deformation of the inner helmet, the display mirror cannot be influenced, the helmet display precision variation canbe reduced, and the stability of the helmet display performance and the adaption of the helmet are improved.

Description

technical field [0001] The invention relates to a helmet body flexible connection structure of a helmet display, which belongs to the field of helmet display assembly and relates to an improvement of the helmet body connection structure of the helmet display. Background technique [0002] With the continuous development of the comprehensive technology of photoelectric aiming display system, the helmet display, as an emerging photoelectric aiming display system, directly projects the display screen into the wearer's eyes, making information transmission faster, more agile and efficient. [0003] The helmet body structure of the helmet display is mainly connected by screws to the outer helmet and the inner helmet. The outer helmet is equipped with an optical imaging system and a display mirror, and the inner helmet is equipped with a chin strap. The front helmet body is connected to a fixed rigid connection. When the inner helmet tightens the chin strap , both sides of the inn...

AI Technical Summary

Problems solved by technology

[0003] The helmet body structure of the helmet display is mainly connected by screws to the outer helmet and the inner helmet. The outer helmet is equipped with an optical imaging system and a display mirror, and the inner helmet is equipped with a chin strap. The front helmet body is connected to a fixed rigid connection. When the inner helmet tightens the chin strap , both sides of the inner helmet will shrink, and the connecting screws on both sides will pull the outer helmet to shrink inward together, and at the same time drive the optical display mirror on the outer helmet to shrink and deform, resulting in fluctuations in the imaging picture and poor display effect

[0004] Because the helmet-mounted display is directly worn on the head, the chin strap must be tightened when wearing the helmet. During this process, the space between the helmet body and the wearer's head needs to be adapted, and the size of the wearer's head varies from individual to individual, causing each person's chin The degree of belt tension is different, the shrinkage of the inner helmet is also different, and the degree of shrinkage and deformation of the outer helmet is also different, resulting in a large deviation in the imaging of the optical display system. Causes the wearer to observe double images on the display screen, resulting in dizziness and discomfort

[0005] Therefore, after the assembly of the helmet-mounted display using the traditional helmet-body connection structure is completed, the display effect of the product varies greatly, and the wearing effect of different people is different. Adapts poorly to the wearer
