Embodiment 1

[0024] Such as figure 1 As shown, the wearing part 1 adopts an earphone type head beam, and its form is to go around the top of the head and clamp the head from both sides. The distance measuring part 2 adopts an ultrasonic distance measuring sensor, and is hinged to one side of the wearing part 1 through a hinge shaft 9 . The input part 3 adopts a button, and the warning part 4 adopts a horn, and they are all installed on the other side of the wearing part 1 . The control part 5 adopts a single-chip microcomputer, and it and the battery 6 are fixed below the distance measuring part 2 and lower than the hinge point, which doubles as a counterweight so that the distance measuring part 2 is always upward. The wires from the single-chip microcomputer 5 to the button 3 and the horn 4 pass through the head beam.

[0025] After the user puts himself in the correct posture, he presses the button to enter the working state. When the user bends over, the horn sounds to remind.

Embodiment 2

[0027] It is basically the same as Embodiment 1, but the warning part 4 adopts a weak current electric shock device, that is, stimulates the skin by electric current to remind the user. Compared with the horn, it has the advantage of being quiet and not overlooked.

Embodiment 3

[0029] Such as figure 2 As shown, the wearing part 1 adopts a visor, which is in the form of a circle around the head, but leaves a space at the top for ventilation. The ranging part 2 adopts a laser ranging sensor, and the control part 5 adopts a single-chip microcomputer, and they are installed in a small box 8 together with a battery 6 and a bluetooth module 7 . The small box 8 is hinged on one side of the wearing part 1 through a hinge shaft 9 . The distance-measuring component 2 is positioned on the top of the small box 8, and is always upward under the counterweight action of other components. The bluetooth module 7 communicates with the mobile phone (not shown in the figure). The corresponding program should be run on the mobile phone.

[0030] After the user puts himself in the right posture, he presses the screen of the mobile phone to enter the working state. When the user bends over, the mobile phone will remind with sound and vibration.

Abstract

The invention relates to a head-mounted instrument, in particular, a head-mounted sitting position detecting device. The head-mounted sitting position detecting device is characterized in that a distance from the head of a user to a ceiling can be measured; the user can be reminded if the sitting position of the user is not correct. The head-mounted sitting position detecting device has the advantages of portable convenience, and accurate reaction.

Description

technical field [0001] The invention belongs to the field of wearable devices, in particular to a head-mounted device that reminds users to maintain a sitting posture and protect eyesight. Background technique [0002] Sitting posture is very important to protect eyesight and protect health, especially for teenagers. There are also many existing technologies for reminding people to keep their sitting posture correct, but they are not perfect. [0003] For example, patents such as publication numbers CN206711354U and CN107242727A are attached to desk lamps, tables, chairs and other items, which also means that users cannot use ordinary desk lamps, desks and chairs, and the environmental adaptability is poor. [0004] Patents such as Publication No. CN107095456A are to place a monitor on the table to monitor the distance from the head (or face) to the table. The disadvantage is that it takes up the desktop, which is not conducive to placing books and school supplies. [000...
