Augmented reality (AR) helmet with lens retracting and releasing function for engineering design

Abstract

The invention relates to an augmented reality (AR) helmet with a lens retracting and releasing function for engineering design. The AR helmet comprises a main body, a camera, two lenses, a retractingand releasing mechanism and two cleaning mechanisms, wherein the retracting and releasing mechanism comprises a first driving assembly, a base, a fixed rod and two rotating assemblies, wherein each rotating assembly comprises a movable rod, a limiting block, a rotating rod, a torsion spring and a spring; each cleaning mechanism comprises a second driving assembly, a transmission assembly, a cleaning assembly, a support rod, a movable frame, two driving rods, two movable blocks, two driving blocks and two bearing seats. The AR helmet with the lens retracting and releasing function for the engineering design is provided with the retracting and releasing mechanism, so that a worker can control the retracting and releasing of the lenses according to the situation; furthermore, the distance between the two lenses can be controlled, so that the practicality of the AR helmet is improved. In addition, the cleaning mechanisms can be used for cleaning water mist and dust on the surfaces of the lenses, so that the clarity of the lenses is improved.

Description

technical field [0001] The invention relates to the field of AR equipment, in particular to an AR helmet with lens retractable function for engineering design. Background technique [0002] Engineering design refers to the entire activity process of providing design documents and drawings with technical basis for the construction of engineering projects, and is an important link in the life cycle of construction projects. AR technology, also known as augmented reality technology, is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. The goal of this technology is to put the virtual world on the screen and interact with the real world. The use of AR technology can combine design documents and drawings with the specific conditions on the construction site, making it easier for engineers or construction personnel to adjust the construction plan.

Problems solved by technology

[0003] When the staff is using the AR helmet for engineering design, sometimes the staff needs to observe the on-site conditions. At this time, the staff needs to take off the helmet. During the engineering design process, the staff needs to keep taking off the AR helmet and Wearing it will greatly reduce the practicability of the AR helmet. Not only that, when the staff enters and exits the room in cold weather, the lens is prone to fogging, which reduces the viewing clarity of the AR helmet and further reduces the The practicality of AR helmets
