Abstract

An assembly system warning device includes a first assembly member, a second assembly member, a main circuit, a power supply, an alarm device, a first circuit, a first switch, a second circuit and a second switch. When the first assembly member is located at an assembly position and the second assembly member is located at an idle position, the main circuit and the second circuit are connected in series to form a closed circuit. When the second assembly member is located at an assembly position and the first assembly member is located at an idle position, the main circuit and the first circuit are connected in series to form a closed circuit.

First claim

What is claimed is:

1. An assembly system warning device disposed on a child safety seat, the assembly system warning device comprising:
a first assembly member and a second assembly member configured to assemble the child safety seat into a vehicle, each of the first assembly member and the second assembly member having an assembly position and an idle position with respect to the child safety seat;
a main circuit having a first end and a second end and being connected in series with a power supply and an alarm device;
a first circuit;
a second circuit;
a first switch having a first end electrically connected to the first end of the main circuit and a second end selectively and electrically connected between the first circuit and the second circuit; and
a second switch having a first end electrically connected to the second end of the main circuit and a second end selectively and electrically connected between the first circuit and the second circuit;
wherein when the first assembly member is located at the assembly position and the second assembly member is located at the idle position, the main circuit and the second circuit are connected in series to form a closed circuit; when the second assembly member is located at the assembly position and the first assembly member is located at the idle position, the main circuit and the first circuit are connected in series to form a closed circuit.

2. The assembly system warning device of claim 1 , wherein when the first assembly member is located at the assembly position and the second assembly member is located at the idle position, the first assembly member triggers the second end of the first switch to be disconnected from the first circuit and electrically connected to the second circuit, so as to form a closed circuit and send out an alarm; when the second assembly member is located at the assembly position and the first assembly member is located at the idle position, the second assembly member triggers the second end of the second switch to be disconnected from the second circuit and electrically connected to the first circuit, so as to form a closed circuit and send out an alarm.

3. The assembly system warning device of claim 1 , wherein when the first assembly member and the second assembly member are located at the assembly positions, the first assembly member and the second assembly member extend from the child safety seat; when the first assembly member and the second assembly member are located at the idle positions, the first assembly member and the second assembly member are stored at storage positions of the child safety seat.

4. The assembly system warning device of claim 1 , wherein at least one of the first assembly member and the second assembly member is an abutting member or an anchor member.

5. The assembly system warning device of claim 4 , wherein the abutting member is a spin-preventing supporting device or a rebound bar of the child safety seat.

6. The assembly system warning device of claim 4 , wherein the anchor member is a top tether, an ISOFIX fixing member or a seat belt fastener.

7. The assembly system warning device of claim 1 , further comprising:
a third switch, a first end of the third switch being electrically connected to the second circuit;
a third circuit, a first end of the third circuit being electrically connected to the first circuit, the third circuit having a first diode;
a fourth circuit, a first end of the fourth circuit being electrically connected to the first circuit, the fourth circuit having a second diode, a current conducting direction of the first diode being opposite to a current conducting direction of the second diode; and
a third assembly member configured to assemble the child safety seat into the vehicle, the third assembly member having an assembly position and an idle position with respect to the child safety seat;
wherein when the first assembly member, the second assembly member and the third assembly member are located at the idle positions, a second end of the third switch is electrically connected to a second end of the third circuit and the first diode is turned off; when the third assembly member is located at the assembly position and the first assembly member and the second assembly member are located at the idle positions, the third assembly member triggers the second end of the third switch to be electrically connected to a second end of the fourth circuit and the second diode is turned on, so as to form a closed circuit and send out an alarm.

8. The assembly system warning device of claim 7 , wherein when the first assembly member, the second assembly member and the third assembly member are located at the assembly positions, the first assembly member, the second assembly member and the third assembly member extend from the child safety seat; when the first assembly member, the second assembly member and the third assembly member are located at the idle positions, the first assembly member, the second assembly member and the third assembly member are stored at storage positions of the child safety seat.

9. The assembly system warning device of claim 7 , wherein the third assembly member is an abutting member or an anchor member.

10. The assembly system warning device of claim 9 , wherein the abutting member is a spin-preventing supporting device or a rebound bar of the child safety seat.

11. The assembly system warning device of claim 9 , wherein the anchor member is a top tether, an ISOFIX fixing member or a seat belt fastener.

12. The assembly system warning device of claim 1 , wherein a first driving unit is disposed between the first assembly member and the first switch; when the first assembly member moves to the assembly position and drives the first driving unit to move, the first driving unit triggers the second end of the first switch to be disconnected from the first circuit and electrically connected to the second circuit.

13. The assembly system warning device of claim 12 , wherein the first driving unit comprises a first driving member, the first driving member is pivotally connected to the child safety seat, the first assembly member is disposed on the first driving member; when the first assembly member drives the first driving member to rotate, the first driving member pushes and triggers the first switch.

14. The assembly system warning device of claim 13 , wherein the first driving unit further comprises an elastic member configured to return the first driving member, the elastic member is disposed between the first driving member and the child safety seat; when the first assembly member drives the first driving member to rotate, the first driving member compresses the elastic member.

15. The assembly system warning device of claim 1 , wherein a second driving unit is disposed between the second assembly member and the second switch; when the second assembly member moves to the assembly position and drives the second driving unit to move, the second driving unit triggers the second end of the second switch to be disconnected from the second circuit and electrically connected to the first circuit.

16. The assembly system warning device of claim 15 , wherein the second driving unit comprises an unlock member and a second driving member, the unlock member is disposed on the second assembly member, the second driving member is connected to the unlock member; when the second assembly member drives the unlock member to move, the unlock member drives the second driving member to push and trigger the second switch.

17. A child safety seat comprising:
