Video timely automatic-moving neck health protection chair

Abstract

The invention discloses a video timely automatic-moving neck health protection chair, which is characterized in that: a power machine adopts a speed reduction motor, and has low output rotating speed, great torque and reliable running; a driving mechanism adopts bevel gear drive and is used for reducing a speed, increasing a force and changing the position configuration of the motor again so as to rationally utilize a space; an execution mechanism adopts a space crank mechanism of which driven elements (a connecting rod and an upright post) have continuously changed speeds, so no impact and vibration is produced; the upright post adopts an angular contact ball bearing, which greatly reduces friction between the upright post and a base and reduces the burden of the execution mechanism; and a rotating chair structure is provided with armrests and a pedal so as to be secure and reliable to use. The video timely automatic-moving neck health protection chair effectively prevents the ankylosis state of a neck when a user uses videos whatever a distance is so as to effectively prevent and cure cervical spondylosis, and does not interfere with any operation so as to be used for all the videos in a computer because the user is hard to be aware of the running of the chair.

Description

technical field [0001] The invention relates to a daily electrical appliance for neck health care, in particular to a real-time video automatic neck health care chair. Background technique [0002] With the advancement of science and technology, people need to spend more and more time facing the display screen, and the neck is glued for longer and longer. This has brought serious consequences to the originally degenerated neck of human beings, that is, The hypertrophy of the posterior longitudinal ligament, the degeneration of the vertebrae and the instability of the facet joints, coupled with the lack of movement of the neck muscles and the atrophy of the muscles, result in instability of the support of the head, which further aggravates the above pathological conditions. Proliferated and thickened ligaments, bone spurs and even herniated intervertebral discs compress nerves and blood vessels, causing cervical spondylosis with various symptoms. In mild cases, dizziness, st...

Problems solved by technology

But there are following problems in these schemes: 1, have used the chair leg pulley without exception, it is conceivable that both feet and the ground have larger frictional resistance, as a result certain wheel frictional force will be far less than the frictional force between transmission systems , the friction between the seat and the buttocks generated by the seat cushion is also relatively large, and the legs must swing with the rotation of the swivel chair. Due to the dynamic relationship between the feet and the wheels, the wheels are very slippery, and there may be wheel movement indefinitely (or left or right or back, etc.); it is more likely that even if you lift your feet or install a pedal, the resistance of the pulley itself and the ground is much smaller than the torsional resistance between the lower end drive structure and the upper end drive structure, and a ridiculous The drive structure at the lower end drives the wheels to rotate, while the upper end remains in the original state; 2. Almost all the schemes are designed to go back and forth in the way of protrusions and stops, although a simple spring damping device is installed (actually, this design should also be equipped with springs and damping mechanisms. ), this impact type method will definitely cause a certain vibration to the human body, which is not suitable for people who are in a leisure or working state; It is a better way to realize the uninterrupted movement of the mechanism, but the arrangement of the mechanism is not in line with the common sense

The general mechanical transmission layout method is to reduce the motor through a gear reducer or directly use a geared motor to drive the actuator after increasing the torque; 4. Both the first two patents mentioned the use of chains in the second scheme. , the existing problem is that the transmission layout is unreasonable

The fatal thing is that if the chain drive is arranged in the horizontal plane, the chain will definitely fall off

5. In order to meet the problem of lifting, each scheme involves a gear with a length of lifting height, but the designer did not consider that such a long gear is difficult to process
