Abstract

A child safety seat alarm system includes a child safety seat, an alarming mechanism, a detection mechanism, a trigger mechanism and a driving portion. The detection mechanism is configured to detect whether both states of the alarming mechanism and the detection mechanism meet a predetermined criterion. The trigger mechanism is switchable between an open state and a closed state. The detection mechanism is in a non-working state when the trigger mechanism is in the open state. The detection mechanism is in a working state when the trigger mechanism is in the closed state. When the child is seated in the child safety seat, the driving portion is operated to switch the trigger mechanism from the open state to the closed state so as to switch the detection mechanism to the working state. When the detection mechanism detects the states of the alarming mechanism and the detection mechanism meet the predetermined criterion, the alarming mechanism outputs an alarm signal for alarming. The child safety seat alarm system can remind a user whether or not a child is left in a car, this would prevent a dangerous scenario that the child is left in the car.

First claim

What is claimed is:

1. A child safety seat alarm system comprising:
a child safety seat for a child to be seated therein;
an alarming mechanism configured to receive a signal and output an alarm signal;
a detection mechanism configured to detect whether both states of the alarming mechanism and the detection mechanism meet a predetermined criterion;
a trigger mechanism switchable between an open state and a closed state, the detection mechanism being in a non-working state when the trigger mechanism is in the open state, the detection mechanism being in a working state when the trigger mechanism is in the closed state; and
a driving portion, when the child is seated in the child safety seat, the driving portion being operated to switch the trigger mechanism from the open state to the closed state so as to switch the detection mechanism to the working state, when the detection mechanism detects the states of the alarming mechanism and the detection mechanism meet the predetermined criterion, the alarming mechanism outputting the alarm signal for alarming.

2. The child safety seat alarm system of claim 1 , 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.

3. The child safety seat alarm system of claim 1 , wherein when the child safety seat receives a pressure or a buckle assembly of the child safety seat is buckled, the child safety seat alarm system confirms that the child is seated in the child safety seat.

4. The child safety seat alarm system of claim 3 , wherein the child safety seat alarm system further comprises a sensing device configured to sense the pressure received by the child safety seat, and when a sensing result of the sensing device is greater than a predetermined pressure value, the child safety seat alarm system confirms that the child is seated in the child safety seat.

5. The child safety seat alarm system of claim 3 , wherein the buckle assembly comprises a male buckle and a female buckle, and when the male buckle and the female buckle are buckled with each other, the child safety seat alarm system confirms that the child is seated in the child safety seat.

6. The child safety seat alarm system of claim 5 , wherein the driving portion and the trigger mechanism are disposed on the buckle assembly, when the male buckle and the female buckle are buckled with each other, the driving portion drives the trigger mechanism to switch from the open state to the closed state, and when the male buckle and the female buckle are unbuckled from each other, the driving portion drives the trigger mechanism to switch from the closed state to the open state.

7. The child safety seat alarm system of claim 6 , wherein the female buckle comprises an accommodating slot, the male buckle comprises an extending portion for cooperating with the accommodating slot, the driving portion is slidably disposed in the accommodating slot, and the extending portion drives the driving portion to abut against the trigger mechanism for switching the trigger mechanism to the closed state when the male buckle and the female buckle are buckled with each other.

8. The child safety seat alarm system of claim 7 , wherein a resilient portion is disposed in the accommodating slot for driving the driving portion to move toward the extending portion.

9. The child safety seat alarm system of claim 7 , wherein a hole is disposed on a wall of the accommodating slot, the trigger mechanism comprises a protrusion stretching into the accommodating slot via the hole, and the driving portion slides to abut against the protrusion thereby switching the trigger mechanism to the closed state.

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

11. The child safety seat alarm system of claim 5 , 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.

12. The child safety seat alarm system of claim 1 , 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.

13. The child safety seat alarm system of claim 12 , wherein the detection mechanism further comprises an USB interface for charging the power source portion.

14. The child safety seat alarm system of claim 12 , 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.

15. The child safety seat alarm system of claim 1 , wherein the alarming mechanism is installed on a mobile terminal of a user.

16. The child safety seat alarm system of claim 1 , wherein the alarming mechanism comprises a key chain for connecting with a car key of a user.

17. The child safety seat alarm system of claim 1 , wherein the alarming mechanism is a mobile phone for receiving the signal and outputting the alarm signal.
