Detailed Description
The following further explains the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 4, the safety warning device with an upper pull belt is arranged on a child safety seat body 1, and comprises a pressure switch 8, a travel switch 6, an elastic element 7, a warning component, and a power supply 10.
The pressure switch 8 is fixed to the seat body 1 at a pressed location, for example, at a hip contact surface of the child safety seat, at a child back contact location, or at another pressed location.
The pressure switch 8 is of a thin plate structure, the positive surface and the negative surface of the pressure switch are respectively provided with a positive electrode and a negative electrode, the positive electrode and the negative electrode are both made of copper sheets, a rebound sponge is arranged between the positive electrode and the negative electrode, the middle part of the rebound sponge is hollow, and a conductive sponge is arranged at the hollow part. When the pressure switch 8 is not subjected to the extrusion force, the positive electrode and the negative electrode have certain gaps with the conductive sponge, the pressure switch 8 is in an off state, and when the pressure switch 8 is subjected to the extrusion force, the positive electrode and the negative electrode are both contacted with the conductive sponge after being extruded, so that the positive electrode and the negative electrode are conducted, and the pressure switch 8 is triggered to be in an on state.
One end of the upper pull belt 3 is fixed in the seat body 1 through a fixing pin 5, and then passes through the lower side of the elastic element 7 and penetrates out through the upper pull belt window of the decorative cover 2, and the other end of the upper pull belt is connected with a hook 4.
The travel switch 6 is arranged on the upper side of the elastic element 7 and comprises an elastic sheet and a contact, one end of the elastic element 7 is in contact with the upper pull belt 3, the other end of the elastic element is in contact with the elastic sheet 6-1, and the travel switch is used for enabling the elastic sheet to trigger the contact when the elastic element 7 is compressed to a certain stroke and enabling the elastic sheet to trigger the contact when the upper pull belt is tightened.
The elastic element 7 may be a torsion spring, a compression spring, or other elastic elements. The illustration of the present embodiment is a torsion spring as an example.
The warning component is a buzzer 11 and/or a warning lamp 9, and the pressure switch 8, the travel switch 6, the warning component and the power supply 10 are connected in series to form a warning circuit. The power source 10 may be a dry cell battery or a button cell battery.
The electric wires of the alarm circuit are all arranged in the child safety seat body 1.
The pressure switch 8 is a normally open type switch, when the pressure switch 8 is not under pressure, the pressure switch is in an off state, the alarm circuit is not conducted, and when the pressure switch 8 is under pressure, the pressure switch is triggered to conduct the alarm circuit.
The travel switch 6 is a normally-closed switch, when the upper pull belt 3 is in an untightened state, the upper pull belt 3 does not extrude the elastic element, when the travel switch 6 is not triggered, the alarm circuit is in a conducting state, when the upper pull belt 3 is tightened, the upper pull belt 3 extrudes the elastic element 7, the elastic iron sheet 6-1 triggers the contact, the travel switch 6 is triggered, and the alarm circuit is disconnected.
This embodiment go up the working process of safety warning device of stretching strap:
when the child safety seat is installed and the hook 4 is forgotten to be mounted on the vehicle, the upper pull belt 3 is in an untightened state, the travel switch 6 is in a normally closed state, the pressure switch 8 is in a normally open state, and the warning circuit is in a disconnected state at the moment. Go up stretching strap 3 for not tightening up the state, if the children sit on the safety seat when tying the safety belt this moment, can extrude the pressure switch 8 that sets up at buttock or back, trigger pressure switch 8, this moment because it is not taut to go up stretching strap 3, travel switch 6 still is the normally closed state, and warning circuit switches on, and warning light 9 and bee calling organ 11 can light and call, remind the user in time to load into the car with couple 4 on, and then avoid going up the condition that stretching strap 3 installed not in place.
And when the installation couple 4 when going to the car, couple 4 can be taut 3 pull-up straps, because fixed pin 5 is motionless, when 4 taut pull-up straps 3 of couple, pull-up straps 3 can have the extrusion force to elastic element 7, and elastic element 7 extrudees travel switch 6's shell fragment, triggers travel switch 6, and travel switch 6 opens this moment, and circuit warning circuit disconnection then warning light 9 and bee calling organ 11 stop work.
Finally, it should be noted that: although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements and the like can be made in the technical solutions of the foregoing embodiments or in some technical features of the foregoing embodiments, but all modifications, equivalents, improvements and the like within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
