Abstract

The invention relates to a device for automatically and accurately adjusting the height and the obliquity of a pillow. The height and the obliquity of the pillow of the pillow must fit the head exactly. In order to adjust the height and the obliquity of the pillow automatically and accurately at the same time, two-layer two-way screw rods applying for the patent are adopted. The key component is a pillow elevating platform which comprises an upper part, a middle part and a lower part, and the three parts are connected by six screw rods; the upper part and the lower part are respectively a plate contacting a bed and a common soft pillow; and the middle part is a driving part for driving the pillow by a stepper motor to lift. In order to monitor and identify the change of sleeping positions, the device adopts a prone position identifying switch block which is in a band form and comprises 15 light diaphragm switches; when being used, the switch block is placed on the bed and in the back and the shoulder positions approximately. In the invention, different thread pitches are designed for the two-layer two-way screw rods, thus the height and the obliquity of the pillow can be changed simultaneously when the pillow is lifted.

Description

Automatically accurately adjust the device of pillow height and gradient

Technical field

The present invention is a device of accurately adjusting pillow height and gradient automatically.

Background technology

People seek various pillows in order to obtain the sleep of high-quality, have special shape, that band fragrance is arranged even in addition with the pillow of Chinese medicine, or the like.In fact, in each sleep, lying on the back and lying on one's side is checker, so pillow the most important thing is height and gradient, must and the cooperation of head precision, reach the health optimum reelability quality.

Summary of the invention

The present invention is in order automatically, accurately to adjust the height and the gradient of pillow simultaneously, and special the employing applied for the double-layer double-direction screw of patent of invention in person.Automatically pillow device has following main accessory: pillow lifting platform (Fig. 1) double-layer double-direction screw (1) to (6), stepper motor (7), driving gear set (8), pillow automatic controller (9), prone position identification switch group (10).By meticulous design, pillow device when low level (Fig. 1) highly has only 40mm to 60mm automatically, even can be lower; When a high position (Fig. 2), height can reach 130mm to 150mm; During use, with after the pressure-bearing height at 20mm with interior daily soft pillow, be fixed on the lifting platform and just can use.In the time of the pillow height automatic lifting, the gradient of pillow is also adjusted simultaneously.The importance majority of pillow height have noticed, but the gradient of pillow is not lain in, important too in fact, because when lying on one's side, shoulder and waist are close to bed, be angled with bed above the waist, keep the normal directly degree of head and physiology above the waist, neck and head must have certain angle with respect to bed; So when lying on one's side, pillow needs gradient, the chances are about 10 degree, varies with each individual.

Description of drawings

Fig. 1 is an automatic pillow device lifting platform (when operating in low level).

Fig. 2 is an automatic pillow device each several part (when operating in a high position).

The specific embodiment

Critical component of the present invention is pillow lifting platform (Fig. 1), and it has three parts in upper, middle and lower, is connected by 6 double-layer double-direction screws, and upward (11), following (12) are the flat board of contact bed and common soft pillow; The centre is a drive part, and two thin plates (13) (14) are arranged, and is equipped with stepper motor, gear train, bearing in the middle of the plate.Drive the elevating movement of pillow by the stepper motor in the middle of being positioned at.

The posture of people when sleeping soundly be can't help, comfortable for health, and lying on the back and lying on one's side is conversion at any time.In order to monitor the change of sleeping position, the present invention adopts prone position identification switch group, is made up of about 15 light and handy diaphragm switches, is designed to band shape, is positioned over during use on the bed, roughly is positioned at back, the shoulder position of health.Because switches set is very thin very light, adds also to have covered the pad quilt, so people are imperceptible when sleeping.When lying on the back, back, shoulder are pressed on the switch, and contact area is big, with the switch closure that has more than 10; When lying on one's side, have only the side of health to be pressed on the switch, contact area is little, will have only 5 with interior switch closure.Therefore, automatic controller just can be monitored the identification sleeping posture at any time, and then the precise motion of control step motor.

When stepper motor moved, gear and nut were driven, and the screw rod in the nut is moving linearly thereupon also, makes pillow do elevating movement.

The present invention is designed to different pitch with double-layer double-direction screw (1) (2) (3) with (4) (5) (6), and therefore, when pillow during in elevating movement, height and gradient can change simultaneously, in order to the conversion of cooperation prone position.

Pillow automatic controller control step motor movement can make pillow reach accurate height and gradient, no matter no matter therefore men and women, old and young's height and weight all can be provided with own use highly as required, this is very important.Therefore people can obtain the sleep of high-quality, away from the worry of cervical vertebra distortion, head anoxic, head hyperemia.Thereby prevent disease is corrected bending, the distortion of health.Have the sleep of high-quality, devote oneself to work with abundant muscle power, the full state of mind every day, enjoys good days.

This is pillow device automatically, and people's demand is very big, and production technology is simple, is fit to produce in enormous quantities.

Claims

1. a device of accurately adjusting pillow height and gradient automatically is characterized in that: comprise pillow lifting platform, double-layer double-direction screw, stepper motor, driving gear set, pillow automatic controller, prone position identification switch group.The lifting platform of automatic pillow device, it has three parts in upper, middle and lower, and in order automatically, accurately to adjust the height and the gradient of pillow, the special employing applied for the double-layer double-direction screw of patent of invention in person; Connect three parts by 6 double-layer double-direction screws; Upper and lower is the flat board of contact bed and common soft pillow, and the centre is a drive part, and two thin plates are arranged, and is equipped with stepper motor, gear train, bearing in the middle of the plate.Drive the elevating movement of pillow by the stepper motor in the middle of being positioned at.Lifting platform also can use common screw rod, make simple relatively, but lifting travel is smaller.

2. according to the said a kind of device of accurately adjusting pillow height and gradient automatically of claim 1, it is characterized in that: in order to monitor the change of sleeping position, the present invention adopts prone position identification switch group, form by about 15 light and handy diaphragm switches, be designed to band shape, be positioned over during use on the bed, roughly be positioned at back, the shoulder position of health.Because switches set is very thin very light, adds also to have covered the pad quilt, so people are imperceptible when sleeping.When lying on the back, back, shoulder are pressed on the switch, and contact area is big, with the switch closure that has more than 10; When lying on one's side, have only the side of health to be pressed on the switch, contact area is little, will have only 5 with interior switch closure.Therefore, automatic controller is monitoring sleep posture at any time just, and then the precise motion of control step motor.
