Abstract

A child safety seat device is provided and includes a child safety seat, a trigger mechanism and a driving portion. The child safety seat is for a child to be seated therein. The child safety seat includes a buckle assembly. The trigger mechanism is switchable between an open state and a closed state. When the buckle assembly is buckled, the driving portion is operated to switch the trigger mechanism from the open state to the closed state. The trigger mechanism of the child safety seat device is switchable between different states by buckling and unbuckling operations of the buckle assembly for preventing a dangerous scenario where the child is left in the car.

First claim

What is claimed is:

1. A child safety seat device comprising:
a child safety seat for a child to be seated therein, the child safety seat comprising a buckle assembly, the buckle assembly comprising a male buckle and a female buckle, the female buckle comprising an accommodating slot, the male buckle comprising an extending portion for cooperating with the accommodating slot, and a hole being disposed on a wall of the accommodating slot;
a trigger mechanism switchable between an open state and a closed state, the trigger mechanism being disposed on the buckle assembly and comprising a protrusion stretching into the accommodating slot via the hole; and
a driving portion slidably disposed in the accommodating slot, the extending portion driving the driving portion to slide to abut against the protrusion of the trigger mechanism for switching the trigger mechanism from the open state to the closed state when the male buckle and the female buckle are buckled with each other, and the driving portion driving the trigger mechanism to switch from the closed state to the open state when the male buckle and the female buckle are unbuckled from each other.

2. The child safety seat device of claim 1 , wherein a resilient portion is disposed in the accommodating slot for driving the driving portion to move toward the extending portion.

3. The child safety seat device of claim 2 , wherein the protrusion comprises a first slanted surface, and the driving portion comprises a second slanted surface for cooperating with the first slanted surface.

4. The child safety seat device of claim 3 , further comprising a detection mechanism configured to detect whether both states of an alarming mechanism separated from the child safety seat device and the detection mechanism meet a predetermined criterion.

5. The child safety seat device of claim 4 , wherein the predetermined criterion is a predetermined distance, and the detection mechanism is configured to detect a distance between the alarming mechanism and the detection mechanism.

6. The child safety seat device of claim 4 , wherein the detection mechanism comprises a detector, a mounting plate and a power source portion, and the power source portion and the detector are disposed on the mounting plate.

7. The child safety seat device of claim 6 , wherein the detection mechanism further comprises an USB interface for charging the power source portion.

8. The child safety seat device of claim 6 , wherein the trigger mechanism is a switch disposed on the mounting plate, the switch in the closed state enables the power source portion to provide electricity for the detector, and the switch in the open state disables the power source portion from providing the electricity for the detector.

9. The child safety seat device of claim 1 , wherein the protrusion comprises a first slanted surface, and the driving portion comprises a second slanted surface for cooperating with the first slanted surface.

10. The child safety seat device of claim 1 , wherein the driving portion is a conductor for conducting a circuit on the male buckle with a circuit on the female buckle when the male buckle and the female buckle are buckled with each other.

11. The child safety seat device of claim 1 , further comprising a detection mechanism configured to detect whether both states of an alarming mechanism separated from the child safety seat device and the detection mechanism meet a predetermined criterion.

12. The child safety seat device of claim 11 , wherein the predetermined criterion is a predetermined distance, and the detection mechanism is configured to detect a distance between the alarming mechanism and the detection mechanism.

13. The child safety seat device of claim 11 , wherein the detection mechanism comprises a detector, a mounting plate and a power source portion, and the power source portion and the detector are disposed on the mounting plate.

14. The child safety seat device of claim 13 , wherein the detection mechanism further comprises an USB interface for charging the power source portion.

15. The child safety seat device of claim 13 , wherein the trigger mechanism is a switch disposed on the mounting plate, the switch in the closed state enables the power source portion to provide electricity for the detector, and the switch in the open state disables the power source portion from providing the electricity for the detector.
