Effect test

Embodiment 1

[0061] Embodiment 1, the projector reciprocates left and right only in the horizontal direction, the projector moves very slowly, the moving speed is: 1-2 cm per minute; the moving speed of the projector can be adjusted.

[0062] When the eyes observe objects in a small range, the eyeballs rotate to expand the field of vision. When the eyeballs still cannot see the corresponding content, the neck needs to be turned to achieve the purpose of expanding the field of vision.

[0063] When operating the computer, the projector moves left and right, and the operator, under the guidance of the projector, turns the head slightly left and right to promote blood circulation and achieve the purpose of relaxing tendons and activating collaterals.

Embodiment 2

[0064] Embodiment 2, the projector reciprocates only vertically up and down, and the projector moves very slowly at a speed of 1-2 centimeters per minute; the moving speed of the projector can be adjusted.

Embodiment 3

[0065] Example 3, small circular trajectory of the projector counterclockwise:

[0066] 1. The starting position is 5-10 cm upward;

[0067] 2. Move 10 cm to the left;

[0068] 3. Move down 5-10 cm;

[0069] 4. Move 20 cm to the right;

[0070] 5. Up 5-10 cm;

[0071] 6. Move 20 cm to the left;

[0072] 7. Return to the starting position and move 10 cm to the right while moving down 5-10 cm.

Abstract

The invention relates to a dynamic adjusting method and a dynamic adjusting device for a projector position. The projector position is dynamically adjusted dependent on time and a projector driven by a position adjusting device to move along a preset track. The dynamic adjusting device comprises a base and the position adjusting device, wherein the position adjusting device comprises an up-down position adjusting device and a left-right position adjusting device. According to the dynamic adjusting method for the projector position, a head of a person watching a projection moves along with a projection screen. The head rotates left and right to a small extent and lifts up and lowers to a small extent unconsciously, so that a paxwax muscle is relaxed properly, combining exertion and rest and preventing over shrinking or stretching a single-sided shoulder muscle, thereby preventing a fixed gesture of the head for a long time, excessive hypsokinesis or anteflexion of the head and neck, fatigue of the neck and cervical vertebra diseases.

Description

technical field [0001] The invention relates to a lifting device, in particular to a method for dynamically adjusting the position of a projector and a dynamic adjusting device. Background technique [0002] Projectors are increasingly used in offices and homes. It can be said that people's work, life and study can no longer be separated from projectors. According to statistics, people spend three to four hours on TV and computers every day. It is difficult to achieve a comfortable posture without looking up or down when watching a projector screen. When working for a long time, you should move your head and neck for 1 hour, so that the cervical ligament muscles can be properly rested, work and rest should be combined, and the exercise of the neck and shoulder muscles should be strengthened to avoid excessive receding or excessive forward bending of the head and neck. For long-term desk workers, it should be about 1 to 2 hours to purposely turn the head and neck to the left...
