AI Technical Summary
Traditional desktop reading and writing devices struggle to simultaneously suppress glare and ghosting, maintain high contrast and clarity in complex lighting environments, and lack ergonomic design and overall system integration mechanisms.
A combination of a concave mirror and a polarizing reflector is used to form a folded optical path. Through magnetic connection and guide design, the height and angle are adjusted with a lifting component to achieve optical path matching and field of view control.
Significantly reduces ghosting and glare, improves contrast and detail clarity in the observation area, reduces neck fatigue, and provides a stable observation environment and energy-saving safety.

Abstract
Claims
1. A read / write station, characterized in that include: Support frame, lifting assembly mounted on the support frame, housing mounted at the output end of the lifting assembly, and optical magnification assembly mounted inside the housing; The housing includes a lower housing and an upper housing rotatably connected to the lower housing; The optical magnification assembly consists of a concave mirror disposed inside the upper shell and a polarizing reflection assembly disposed on the lower shell; The polarization reflection assembly is rotatably connected to the lower shell. The polarization reflection assembly includes a frame for mounting and an optical laminate fixed within the frame. The optical laminate includes a first transparent substrate, a reflective polarizer, a quarter-wave plate, and a second transparent substrate arranged sequentially within the frame, or a third transparent substrate, a second quarter-wave plate, a second reflective polarizer, a third quarter-wave plate, and a fourth transparent substrate. The upper shell is also provided with a slidable baffle. The baffle is disposed relative to the concave mirror and moves along the guide portion of the upper shell to shield the edge area of the concave mirror during reflection to prevent the edge of the frame from being exposed in the user's field of vision.
2. The station of claim 1, wherein The lower shell, frame, and upper shell are all equipped with magnetic suction components, so that when the shell is closed, the lower shell, frame, and upper shell are magnetically aligned and connected.
3. The station of claim 2, wherein The bottom side of the frame is provided with a light strip facing the lower shell; a magnetic sensor is provided on the lower shell and a magnet is provided on the frame opposite to it. When the upper shell and the lower shell are closed, the magnetic sensor outputs a signal to the control board inside the lower shell to control the light strip to turn off.
4. The station of claim 3, wherein The lower end of the lower shell is also equipped with a power off button, an up button and a down button, a power on button, a display screen, and multiple light adjustment buttons; the power off button, the up button and the down button, and the power on button are arranged sequentially on one side of the lower end of the lower shell, the display screen is arranged in the middle of the lower end of the lower shell, and the multiple light adjustment buttons are arranged on the other side of the lower shell. The corresponding terminals of the control motherboard are electrically connected to the power off button, the up button and the down button, the power on button, the display screen, multiple light adjustment buttons, and the corresponding terminals of the lifting assembly.
5. The station of claim 1, wherein The support frame includes a U-shaped base and a support sleeve connected to the U-shaped base; the inner cavity of the U-shaped base is used to place books or smart terminals; and the bottom of the U-shaped base is also provided with anti-slip pads.
6. The station of claim 1, wherein The lifting assembly includes a hydraulic rod disposed inside a support sleeve, the output end of which is fixed to the lower shell; the lower shell is also provided with a sleeve, which is fitted onto the support sleeve and can slide up and down along the support sleeve when driven by the hydraulic rod.
7. A station according to claim 6, c h a r a c t e r i z e d in that The lower shell also has corresponding fixing grooves at its four corners for placing magnets to fix the sheet material suspended on the lower shell.
8. A station according to claim 7, c h a r a c t e r i z e d in that The polarization reflection component rotates along the lower shell at an angle ranging from 0 to 60°; the upper shell rotates along the lower shell at an angle ranging from 0 to 105°.
9. The station of claim 1, wherein, The reflecting concave mirror is a spherical or aspherical concave mirror, and its radius of curvature ranges from 800mm to 15000mm.
10. The station of claim 1, wherein The guide portion of the upper shell includes multiple side-by-side waist-shaped or elongated slots. The baffle is mounted on the waist-shaped slot by screws and can slide along the waist-shaped or elongated slot.
