DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides a technical solution: a desk with intelligent eye protection function, comprising a desk body 1 and a bookcase 2 arranged on the upper surface of the desk body 1, the bookcase 2 being vertically arranged at the edge of the upper side of the desk body 1, away from the sitting position; an adjustable photosensitive sensor 6 and a lamp holder 3 are arranged on the upper side of the side surface of the bookcase 2 from top to bottom, an LED adjustment lamp 4 is installed on the inner side of the lamp holder 3, a controller 13 is installed inside the desk body 1, the controller 13 is preferably a PLC controller, such as the PLC controller of the Mitsubishi FX2N series, the controller 13 is electrically connected to an external power supply 14, the photosensitive sensor 6 and the LED adjustment lamp 4 are both electrically connected to the controller 13, the photosensitive sensor 6 arranged on the upper side of the lamp holder 3 is used to detect the light intensity of the external environment and transmit a corresponding signal to the controller 13, the controller 13 automatically turns on and adjusts the brightness of the LED adjustment lamp 4, which greatly improves the intelligence of the eye protection function, is simple to operate, and is easy to use, and is especially suitable for use by younger children and teenagers.

[0019] According to a preferred technical solution, a slide groove 5 is provided on the upper portion of the side surface of the bookcase 2, and the shell portion of the photosensitive sensor 6 is slidably arranged in the slide groove 5. The photosensitive sensor 6 can adjust its position, so as to be flexibly adjusted to a suitable position according to the placement position of the table body 1 and the direction of the window, thereby preventing the light intensity outside the window from affecting the light intensity judgment of the photosensitive sensor 6 on the overall environment around the table body 1, making the adjustment more precise and improving the eye protection effect.

[0020] A further preferred technical solution is that the slide groove 5 is a strip-shaped hole connected end to end, and a dustproof belt 12 is slidably arranged in the slide groove 5. The two ends of the dustproof belt 12 are respectively arranged on the two side surfaces of the outer shell of the photosensitive sensor 6. The dustproof belt 12 is preferably made of a hard and elastic material, such as an alloy or a tough plastic. When the photosensitive sensor 6 slides in the slide groove 5 to adjust its position, the dustproof belt 12 also rotates in the slide groove 5, which always closes the slide groove 5, thereby reducing dust falling into it and avoiding affecting the adjustment of the photosensitive sensor 6.

[0021] According to the preferred technical solution, a vertically arranged mounting frame 7 is installed in the middle of the side surface of the bookcase 2, and an infrared sensor group 8 is installed on the side surface of the mounting frame 7. The infrared sensor group 8 is electrically connected to the controller 13. The infrared sensor group 8 includes a plurality of infrared sensors arranged in sequence from top to bottom. The infrared sensor is preferably a sensor commonly used in the prior art for detecting the human body. The sitting posture of the teenager sitting in front of the table 1 is auxiliary detected by the infrared sensor group 8 arranged on the mounting frame 7, and a timely reminder is given when the sitting posture is abnormal, so as to avoid affecting the vision due to incorrect sitting posture, thereby further improving the eye protection effect.

[0022] Specifically, a vibration panel 11 is provided on the desktop of the table body 1, and a vibration motor 15 is provided on the lower surface of the vibration panel 11. The vibration motor 15 is electrically connected to the controller 13. The controller 13 is operated according to the height and body shape of the teenager, and the detection height is set. When the teenager sits in front of the table body 1 to study, several infrared sensors corresponding to his head in the infrared sensor group 8 detect his head and transmit corresponding signals to the controller 13. The controller 13 determines that the sitting posture is normal; when the teenager lowers his head to a greater extent, which may affect his eyesight, the infrared sensor located on the upper side cannot detect his head, that is, it cannot send a corresponding signal to the controller 13. The controller 13 determines that the sitting posture is abnormal, turns on the vibration motor 15, and vibrates the vibration panel 11, so as to promptly remind the teenager to maintain a correct sitting posture, thereby improving the eye protection effect.

[0023] The LED adjustment lamp 4, photosensor 6, infrared sensor, vibration motor 15 and controller 13 used in this application are all electronic components commonly used in the prior art. Their specific structures, working principles and circuit connections are all well-known technologies and will not be described in detail here.

[0024] Most of the desks with detection reminder functions on the market use sound reminders, which will interrupt the user's learning train of thought. However, this application uses vibration to remind the user, which is relatively gentle and reduces the impact on the user and the people around him.

[0025] According to a preferred technical solution, two vertically arranged movable frames 9 are symmetrically installed on the side surface of the bookcase 2, and an infrared sensor group 8 is arranged on the side surface of the movable frame 9 to assist in detecting the user's sitting posture to prevent the user from "staggering" while studying and affecting vision.

[0026] A further preferred technical solution is that two groups of T-shaped guide rails 10 are symmetrically fixed on both sides of the side surface of the bookcase 2, and the movable frame 9 is slidably set on the guide rails 10, and the sliding direction is perpendicular to the length direction of the movable frame 9. The movable frame 9 can move laterally to adjust its position, and can be flexibly adjusted according to the user's body shape and height, thereby improving universality.

[0027] The undisclosed parts in the present utility model are all prior art, and their specific structures, materials and working principles are not described in detail. Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the attached claims and their equivalents.
