Description

Intelligent bed fence

Technical Field

The invention belongs to the field of children furniture, and particularly relates to an intelligent bed fence.

Background

The child enclosure frees the caregiver's hands and provides a safe place for the child to move about. Especially, the intelligent bed fence used on the bed plays a great role in preventing the baby from falling off the bed.

On the other hand, the infants have long sleeping time but weak resistance, and people like kicking quilts, and when sleeping, the electric fan or the window blows in and directly faces to the wind of the infants, so that the infants are easy to catch cold to cause other diseases. Therefore, a fixed wind shield is generally installed on the crib or cradle for the baby sheet, such as a wooden crib disclosed in utility models CN201929498U and CN201591374U, and a multifunctional medical crib disclosed in utility model CN 205696858U.

The fixed wind shield is obviously not suitable for bed fences, the length and the area of the bed fence are usually much larger than those of a crib and a cradle, the bed fence is generally fixedly arranged on the bed, the bed fence can not be conveniently turned like the crib and the cradle, meanwhile, the wind direction of external wind is not fixed, and a baby can often turn over and change positions when sleeping in the bed fence. Some parents may use some cloth or clothes to hang on the vertical edge or add one or more fixed wind shields on the bed fence to partially shield the wind, but such operation increases the burden of the user, and cannot ensure that the wind-shielding object is always positioned at the wind-shielding position, and especially, the effectiveness of wind shielding is difficult to ensure after the parents fall asleep. If the wind which blows the baby directly in all directions is blocked, the wind blocking plates are only used for blocking the periphery of the fence or the breathable net cloth on the periphery is made into an airtight entity, so that the ventilation and/or light of the whole sleeping area is affected, and the sleeping area is obviously unreasonable and inconvenient.

Specifically, the upper cross frame 1 is a hollow cylinder, and the surface thereof is provided with a groove C extending in the axial direction. A plurality of wind shielding rolls 6 are installed in the inner cavity of the upper cross frame 1. The wind shielding roll 6 comprises a left baffle 61, a right baffle 62, a scroll 63 and a motor frame 64, two ends of the scroll are respectively inserted on a shaft seat 65 of the left baffle and a shaft seat 66 of the right baffle, woven fabric (not shown) is wound on the scroll 63, one end of the woven fabric is fixed on the scroll, the other end of the woven fabric passes through a groove C on the upper transverse frame 1, and a motor 67 for controlling the woven fabric to be wound up or put down is arranged in the motor frame 64; the motor frame 64 is positioned between the left baffle plate and the right baffle plate, is integrated with the right baffle plate, is approximately in an inverted U shape, and is provided with an opening below; through which a motor 67 is drivingly connected to the reel 63 by means of a belt (not shown), which motor, when activated, rotates the reel 63 and thereby winds or unwinds the fabric.

Axle seats 66 are arranged on two side surfaces of the right baffle plate 62, and when a plurality of wind shielding rolls 6 are connected in series, the reel of the rear wind shielding roll is inserted into the axle seat of the right baffle plate of the front wind shielding roll.

As shown in fig. 6-7, in this embodiment, the length of the bed is 200cm, the width is 180cm, the width of the fabric is 20cm, and the determining of the first area 16 specifically includes the following steps:

(1) acquiring an image of an unmanned bed surface in a fence on a bed, and carrying out grid division on the image, wherein the unit length of a grid is a square of 20cm, the length of a corresponding bed blank image is 200cm, the width of the corresponding bed blank image is 180cm, the number of long-side grids after the blank image is subjected to grid formation is 10, and the number of short-side grids is 9; the gridded image is stored as a first image 17;

(2) acquiring a second infrared image of the surface of the manned bed;

(3) comparing said second image with the first image, mapping the infrared pattern 18 representing the person in the second image onto the grid of the first image;

in this embodiment, as a preferable scheme, in this step, the size of the infrared image 18 may be compared first, and whether the child is a child is evaluated according to the number of the occupied lattices, and only when the size is smaller than a certain value, that is, when the child is judged to be a child, the next step is continued.

(4) The infrared pattern 18 is projected against the wind direction 9 towards the edges of the grid, and all the grids swept by the projection are determined as the first area 16 to be shielded from the wind.

After the first area 16 is determined, the intersection line of the first area 16 and the outer edge of the grid is determined as a designated wind shielding position 19, and then a command is sent to a motor controller of one or more wind shielding rolls at the designated wind shielding position to control the woven fabric at the position to be laid down so as to form a wind shielding layer on the fencing cloth at the position. Obviously, the motor controller of the wind shielding roll in the non-wind shielding position gives an instruction to maintain the rolling state of the woven fabric at the position or roll the woven fabric at the position.

As shown in fig. 8 to 9, the second control unit sets a wind speed threshold value, and when the wind speed exceeds the threshold value, the first area is expanded by one grid along the periphery as a corrected first area, and the corresponding wind shielding position is changed to 20.

As shown in fig. 10 to 11, a user selection of three states, namely, a child-resistant state, a general state and a cold-resistant state, is configured on the mobile terminal 15, for example, a mobile phone, and after the user selects the three states, the data transmission unit 14 transmits the received selection to the third control unit, and the third control unit correspondingly enlarges or retracts one grid for each of the first area along the periphery to serve as the corrected first area; for example, a baby is more sweaty and less in clothes, is pleased with cold at ordinary times, the mobile phone end is selected to be afraid of heat, the third control unit correspondingly houses a grid in the fixed wind shielding position area, and the corrected wind shielding position 21 is correspondingly determined.
