Description

Safety alarm for children in vehicle

Technical Field

The utility model relates to a children's articles for use field especially relates to an interior children's safety alarm of car.

Background

In real life, people often drive a car independently and go out with children, and sometimes adults leave the car independently due to an emergency and leave the children in the sealed car, so that the children are in a very dangerous situation. In real life, the child is hot and sultry because the child is left in the car. Even if some parents get off the car only temporarily to handle things for a while, the temperature in the car can change greatly within a short time of several minutes, the temperature can rise very fast, and because doors and windows are closed, oxygen in the car can be more and more sparse, so that children are easy to suffocate.

After the installation of children's seat finishes, the safety buckle of seat is one of the core part of guaranteeing children's safety, and the safety belt can effectively reduce the injury to passenger's health when the traffic accident appears, must detain safety buckle and just can guarantee baby's safety, and present safety seat does not target in place to the safety belt and detects, if the safety belt does not have the lock to target in place then causes the potential safety hazard. Moreover, the existing child seat only detects whether a child is on the seat through a pressure sensor, and if the child is placed on the seat, the child cannot be detected, so that detection errors are caused, and false alarms are generated.

Accordingly, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects of the prior art and providing a child safety alarm in a car.

The technical scheme of the utility model as follows: an in-vehicle child safety alarm comprising: the seat comprises a seat body, a cushion arranged on the seat body, a gravity sensor arranged below the cushion, a plug-in component connected with the seat body, a plug component connected with the seat body, a Hall sensor, a first temperature sensor, a buzzer and a control center, wherein the gravity sensor, the first temperature sensor, the buzzer and the Hall sensor are respectively and electrically connected with the control center;

the plug assembly includes: the plug seat, locate the plug of plug seat bottom, with the first telescopic band that the left end of plug seat is connected, and with the second telescopic band that the right-hand member of plug seat is connected, the eye-splice subassembly includes the eye-splice, hall sensor includes magnetism end and response end, magnetism end and response end are installed respectively on plug subassembly and eye-splice subassembly, first temperature sensor locates the inboard of first telescopic band or second telescopic band, when eye-splice and plug lock, the contact of children on first temperature sensor and the seat body, first temperature sensor is used for responding to the body temperature of children on the seat body.

Furthermore, the child safety alarm in the car further comprises a second temperature sensor connected with the control center, the second temperature sensor is used for detecting the ambient temperature in the car, the control center is connected with a central control unit of the car, and the central control unit is electrically connected with a car air conditioner.

Furthermore, the central control unit is electrically connected with the automobile horn.

Further, the eye-splice assembly includes a third expansion band connected with the eye-splice.

By adopting the scheme, the utility model discloses following beneficial effect has:

1. the utility model detects whether the safety belt is buckled or not through the Hall sensor, and sends out an alarm to remind parents if the safety belt is not buckled, thereby ensuring the safety of children;

2. whether children exist on the seat is doubly sensed through the gravity sensor and the first temperature sensor, so that the accuracy of judgment is improved;

3. detect the ambient temperature in the car through second temperature sensor, if the high temperature, then control car air conditioner and open, prevent that children suffocate in the car.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the present invention provides an in-car children safety alarm, including: the seat comprises a seat body, a seat cushion arranged on the seat body, a gravity sensor arranged below the seat cushion, a plug-in component 1 connected with the seat body, aplug component 2 connected with the seat body, a Hall sensor, a first temperature sensor, a buzzer and a control center, wherein the gravity sensor, the first temperature sensor, the buzzer and the Hall sensor are respectively electrically connected with the control center.

Theplug assembly 2 includes: theplug seat 21, locateplug 22 ofplug seat 21 bottom, with the firsttelescopic band 23 of the left end connection ofplug seat 21, and with the secondtelescopic band 24 of the right-hand member connection ofplug seat 21. The eye-splice component 1 comprises an eye-splice, theplug 22 is inserted into the eye-splice, when theplug 22 is buckled with the eye-splice, the firsttelescopic belt 23 is sleeved on the left shoulder of the child, and the secondtelescopic belt 24 is sleeved on the right shoulder of the child. Hall sensor includes magnetism end and response end, magnetism end and response end are installed respectively onplug subassembly 2 and eye-splice subassembly 1 for whetherresponse plug subassembly 2 and eye-splice subassembly 1 are buckled well, if Hall sensor detects not to have the lock well then send signal for control center, control center control buzzer sends the police dispatch newspaper sound, gives the head of a family and reminds.

The first temperature sensor is arranged on the inner side of the firsttelescopic belt 23 or the inner side of the secondtelescopic belt 24, when the plug buckle is buckled with theplug 22, the first temperature sensor is in contact with children on the seat body, and the first temperature sensor is used for sensing the body temperature of the children on the seat body. Because the traditional child alarm device is only provided with a gravity sensor to detect whether a child is on the seat or not, false alarm can be generated when an object is placed on the seat. The utility model discloses add first temperature sensor on original basis, whether have children on responding to the seat through first temperature sensor, increased the accuracy of judgement. After the automobile is flamed out and the parent gets off the automobile, if the child is still sensed to be on the seat, the buzzer is controlled to give out an alarm sound to remind the child to be left out on the automobile.

The eye-splice assembly 1 comprises a thirdtelescopic strap 11 connected to the eye-splice.

The child safety alarm in the car further comprises a second temperature sensor connected with the control center, the second temperature sensor is used for detecting the ambient temperature in the car, the control center is connected with a central control unit of the car, and the central control unit is electrically connected with a car air conditioner. When the gravity sensor and the first temperature sensor sense that children are on the seat, and the second temperature sensor detects that the ambient temperature in the car is high, the central control unit controls the air conditioner in the car to be turned on.

Well accuse unit and auto horn electric connection, after the car head of a family gets off the bus, if still sense to omit on the seat and have children, not only control buzzer and take place sound, still control auto horn sound production after a period, play better warning effect.

To sum up, the utility model discloses following beneficial effect has:

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
