Push-button sitting posture reminding instrument

Technical Field

The utility model relates to a technical field is rectified to the position of sitting relates to a position of sitting reminds the appearance, especially relates to a press-key position of sitting reminds the appearance.

Background

For students in middle and primary schools, the learning state of daily learning is a problem which cannot be ignored, and good learning state can concentrate attention and improve learning efficiency. An obvious index of the learning state is the personal sitting posture standard degree, and the standard sitting posture enables others to feel that the person is in a state of concentration at a glance. The irregular sitting posture not only can lead to the attention being not concentrated enough to influence the learning efficiency, but also can influence the body health more seriously. Research shows that the vision of students is affected when the students lean forward in head and read and write too close to books during learning, and the situations of myopia, high myopia and the like are caused when the students cannot sit in a non-standard posture for a long time. The habit of sitting untimely and keeping bending and humpback of students not only affects the personal image and quality of qi, but also affects the normal development of students and induces various diseases such as scoliosis, cervical spondylosis, lumbar spondylosis and the like.

The sitting posture problem of the students is not worried about for the self-disciplined students as to how to keep the students in the correct sitting posture; however, for the involuntary students, only the teacher or the parents can supervise and urge the students at ordinary times, but the effect of the method is not ideal, because some students are unconscious due to untimely sitting postures, and habits are naturally formed over time, so that the learning state is influenced. For teachers, it is almost impossible to give a lecture on a platform and to note whether the learning state or sitting posture of dozens of people in the whole class is problematic. For parents, the children can only watch the learning condition occasionally, and the parents cannot watch the sitting posture of the children at all times. For this reason, instruments and devices related to sitting posture reminding are gradually generated.

The existing sitting posture reminding instrument mainly comprises a hanging neck type instrument, a desktop supporting type instrument and a desktop placing type instrument.

The so-called neck hanging type is shown in fig. 1, which means that a user hangs an instrument on the neck, the main instrument is attached to the back, when the user bends down and bends his head, the inclination angle of the instrument is driven to change and a threshold value is triggered to remind the user to adjust and maintain a standard sitting posture. Although the hanging neck type reminding instrument reminds a user of normalizing the sitting posture by detecting the bending amplitude of the back, the hanging neck type reminding instrument can not detect the distance between eyes of the user and a desktop due to the fact that the hanging neck type reminding instrument is attached to the back of the user, and the sitting posture correction effect of the user is limited.

The so-called desktop supporting type is shown in figure 2, and means that the supporting device is fixed on a desktop, and on one hand, the supporting device can limit the minimum distance from the head to the desktop and prevent the head and eyes from being too close to the desktop; the support device can also limit the forward leaning of the user's body. This bearing formula device can effectively avoid user's eyes to be too close to the desktop, but in the in-service use process, especially long-term use in-process, the user can habitually lean on the health to press on bearing formula device, and the head is directly placed on bearing formula device's U type rack, and the above-mentioned health part of user desktop all directly leans on to press on bearing formula device, and oneself need not or use a small part of strength can, form worse position of sitting custom over a long time.

The desktop placement type is, as shown in fig. 3, that is, the reminder is placed at a certain distance right in front of the desktop exercise book, and the reminder reminds the user to adjust the sitting posture by measuring the distance between the head or eyes of the user and the reminder when the distance is too short. However, the reminder can only measure the distance between the head or eyes of the user and the reminder, and when the distance does not trigger the threshold, the head or eyes of the user are too close to the desktop, so that the reminder cannot accurately detect the problem that the eyes of the user are too close to the desktop.

In order to realize distance detection, the conventional reminding instrument is easy to damage eyes of a user due to the fact that common laser has strong light, and therefore the distance detection is carried out by adopting the principle of ultrasonic ranging or infrared ranging; and when the detected distance is smaller than the threshold value, reminding and prompting are triggered. However, when the reminder using ultrasonic ranging or infrared ranging is used, the ultrasonic ranging or infrared ranging can cause an obvious near-field detection phenomenon, which causes a serious false alarm situation of the reminder and affects the use effect of a user. In addition, the desktop among the prior art is placed formula and is reminded the appearance, and it is that it is direct to place the instrument on the desktop, thereby reminds the appearance to take place the displacement easily under the exogenic action and lets the range finding more inaccurate, can cause the instrument to drop the damage even. Most of the existing reminding instruments are started, closed, awakened or dormant through on-off keys on the instruments, and the existing reminding instruments cannot be automatically started, closed, awakened or dormant according to the using environment; and after the reminding instrument detects that the distance is too close to trigger reminding or prompting, most of the reminding instruments only remind in a voice prompting mode, the reminding mode is too single, and the reminding strength cannot be adjusted. In addition, the threshold value of the existing reminding instrument is mostly directly preset in advance, and the threshold value is inconvenient to adjust in the later period; or the cost of implementing threshold adjustment is high, such as the need for a companion APP.
