Abstract

A secondary reflector is composed of two reflectors, and is characterized in that a reflector with a proper size is arranged at a reflecting point according to the change width of an object image light range at the reflecting point according to the principle that the object image light range at a distance is gradually narrowed to form a triangle to be incident into eyes, the reflector is arranged on a light incident path, the object image propagation direction is changed, object image FG light rays firstly enter a DE part of the reflector 1, are reflected to a BC part of the reflector 2 through the reflector 1, and are reflected to the viewing point A through the reflector 2. One or two of the reflectors totally or partially use a curved mirror to adjust the size of the object image. And a lens is arranged on the object image propagation path to adjust the size of the object image. The mirror 2 is located in front of the area between the mirror 1 and the viewing object plane. After the object plane light is reflected by the second stage, the object image direction is kept unchanged, and further, the object image direction is kept unchanged, namely the front end object point is positioned above the sight line, and the rear end object point is positioned below the sight line. The observation object plane is below the viewpoint in front of the viewpoint.

Description

Secondary reflector

Technical Field

The invention relates to a reflector, in particular to a secondary reflector.

Background

In working life, the head is often needed to be lowered for observation and operation, and the health is seriously influenced for a long time. On 31/8/2020, a head-up display projection apparatus is disclosed under the application numbers CN202010606917.1 and CN 111562677A. However, the electronic image processing system is used for displaying, so that the problems of visual fatigue, visual acuity influence and image distortion are easily caused.

Disclosure of Invention

The invention aims to design a reflector to change the height, direction and distance of an image point to be watched, so that the watching meets the health requirement.

The technical implementation scheme of the invention is as follows: a secondary reflector is composed of two reflectors, and is characterized in that a reflector with a proper size is arranged at a reflecting point according to the change width of an object image light range at the reflecting point according to the principle that the object image light range at a distance is gradually narrowed to form a triangle to be incident into eyes, the reflector is arranged on a light incident path, the object image propagation direction is changed, object image FG light rays firstly enter a DE part of the reflector 1, are reflected to a BC part of the reflector 2 through the reflector 1, and are reflected to the viewing point A through the reflector 2. One or two of the reflectors totally or partially use a curved mirror to adjust the size of the object image. And a lens is arranged on the object image propagation path to adjust the size of the object image. The mirror 2 is located in front of the area between the mirror 1 and the viewing object plane. After the object plane light is reflected by the second stage, the object image direction is kept unchanged, and further, the object image direction is kept unchanged, namely the front end object point is positioned above the sight line, and the rear end object point is positioned below the sight line. The observation object plane is below the viewpoint in front of the viewpoint. The intersecting lines of the reflector 1, the reflector 2 and the observation object plane are parallel. The intersection line of the planes of the reflector 1, the reflector 2 and the object plane to be observed is vertical to the central line (AH) of the sight line right in front of the object plane to be observed. The angle and the position of the reflector can be adjusted. And arranging a light source or a reflection light source in the imaging direction of the object surface to be observed so that the object surface is irradiated to the visual imaging direction. The device is mainly used for reading, writing, observing and operating electronic equipment and kitchen ware, and can also be used for industrial manual operation. The reflector 1 is integrated with the range hood, and the reflector 1 is arranged on the outer side of an air port of the range hood. The support is integrated with the chopping board, and the chopping board is fixed at the bottom of the support. The bracket is provided with an electric device to realize automatic rising and falling. And a three-stage or multi-stage reflector can be arranged by utilizing the triangular principle of an incident path, so that more functions are realized.

The invention has the beneficial effects that: the reading and writing can keep a healthy viewing distance, protect the eyesight, avoid lowering the head and protect the health of the cervical vertebra; the electronic display equipment is operated and watched without lowering the head, so that the cervical vertebra is protected to be healthy; the user does not need to bend down and lower the head when cooking, thereby protecting the health of cervical vertebra and lumbar vertebra and improving the life quality.

One embodiment of the present invention: the embodiment is one of the embodiments of the present invention, and the scope of the present invention is not limited thereto. As shown in fig. 4, a rectangular plane mirror is used as the reflecting mirror 1, a concave mirror is arranged in the middle of the reflecting mirror 1, the rectangular plane mirror is used as the reflecting mirror 2, the processing size of the

reflecting mirrors

1 and 2 is slightly larger than that of the schematic diagram, the device is convenient to adjust, and the two sides of the reflecting mirror 1 and the reflecting mirror 2 are fixed and supported by using a support 3. Watch the object plane and be computer keyboard, use the trapezoidal support frame of perpendicular image plane between the both ends of speculum 1 and image, support frame top and speculum 1 both sides intermediate junction are fixed, and speculum 1 can rotate at the axis between the both sides tie point to the angle of adjustment, high accessible support is adjusted, and speculum 2 is located the front lower place of speculum 1. The upper edge of the two side fixing frames is connected with the transverse rod, extends towards the front end and is fixedly connected with the left end and the right end of the reflector 2, and the front-back distance between the upper edge of the two side fixing frames and the reflector 2 can be adjusted through screws.
