Technical Field

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

Background

The child enclosure frees the caregiver's hands and provides a safe place for the child to move about. In particular, the child enclosure 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. In the actual use of the prior art fence as shown in fig. 8, some parents may use some cloth or clothes to hang on the vertical edge or add one or more fixed wind shields to the fence in bed to partially shield the wind, but such operation imposes a burden on the user and cannot ensure that the wind shields are always located 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.

Disclosure of Invention

Aiming at the problems, the invention provides an intelligent windproof children fence. The technical scheme is as follows:

the child enclosure includes an enclosure portion, a data portion, and a control portion, wherein,

the fence part comprises a fence body fixed on the bed and a plurality of wind shielding devices arranged on the fence body;

the wind shielding device comprises wind shielding cloth, a motor for controlling the wind shielding cloth to be rolled up or put down, and a motor controller;

the data part comprises an infrared image sensor used for acquiring a bed surface image in the child fence and a wind sensor used for measuring the wind direction of wind blowing to the fence;

the control part determines a first area needing wind shielding in the child enclosure according to the bed surface image and the wind direction, and sends an instruction to a motor controller of one or more designated wind shielding devices according to the first area.

Further, the determining of the first area specifically includes the following steps:

(1) acquiring an image of an unmanned bed surface in a child fence, meshing the image, and storing the meshed image as a first image;

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

(3) comparing the second image with the first image, and mapping the infrared graph representing the person in the second image onto the grid of the first image;

(4) and projecting the infrared pattern to the edge of the grid against the wind direction, and determining all the grids scanned by projection as a first area needing to block the wind.

Further, after the first area is determined, the control part determines the intersection line of the first area and the outer edge of the grid as a designated wind shielding position, immediately sends an instruction to the motor controllers of one or more wind shielding devices at the designated wind shielding position, and controls the wind shielding cloth at the position to be put down so as to form a wind shielding layer on the fence cloth at the position.

Obviously, the control unit instructs the motor controller of the windshield device in the non-windshield position to maintain the windup state of the windshield cloth in the position, or to wind the windshield cloth in the position.

Further, in the step (1) of determining the first region, the step of meshing the image specifically includes:

A. determining the unit length of the grid to be L according to the width of the wind-blocking cloth, wherein the grid is square;

B. the number of grids of the long side and the short side of the fence is determined according to the length and the width of the fence divided by the unit length of the grids.

Further, the installation position of the wind shielding device corresponds to the divided grids.

The invention has the beneficial effects that: when a baby sleeps in the bed fence, the baby often turns over to change the position, when wind is in the outside and the wind direction is not fixed, the child is dynamically shielded by the intelligent windproof child fence according to the wind direction and different positions of the child on the bed, possible wind blowing to the baby in all directions is blocked, ventilation on the whole bed is not affected, and the burden of adults caring for the child is relieved.

A plurality of windshields 5 are mounted in the interior cavity of the upper cross frame 6. The wind shielding device 5 comprises a left baffle 51, a right baffle 52, a scroll 53 and a motor frame 54, wherein two ends of the scroll are respectively inserted on a shaft seat 55 of the left baffle and a shaft seat 56 of the right baffle, wind shielding cloth (not shown) is wound on the scroll 53, one end of the wind shielding cloth is fixed on the scroll, the other end of the wind shielding cloth passes through a groove 61 on the upper cross frame 6, and a motor 57 for controlling the wind shielding cloth to be wound up or put down is arranged in the motor frame 54; the motor frame 54 is positioned between the left baffle and the right baffle, is integrated with the right baffle, is approximately in an inverted U shape, and is provided with an opening below; through which the motor 57 is drivingly connected to the reel 53 by means of a drive belt (not shown), and when the motor is driven, the reel 53 is rotated, thereby winding or unwinding the windshield cloth.

Axle seats 56 are provided on both sides of the right baffle 52, and when a plurality of windshields 5 are connected in series, the spool of the rear windshield is inserted into the axle seat of the right baffle of the front windshield.

The outer diameters of the left baffle and the right baffle correspond to the inner diameter of the upper transverse frame.

As shown in fig. 6 and 7, the control part 2 determines a first area 15 in the child enclosure, which needs to be shielded from wind, according to the bed surface image 12 and the wind direction 13, wherein the length of the bed is 200cm, the width of the bed is 180cm, and the width of the wind-shielding cloth is 20cm in the present embodiment.
