DETAILED DESCRIPTION

Detailed description of the embodiments of the present invention is illustrated with the accompanying drawings. Similar components are marked with similar reference numerals in the drawings.

Please refer toFIG.1toFIG.6. A child safety seat alarm system of the present invention includes a child safety seat10, an alarming device20, a detection mechanism30and a driving portion40. The child safety seat10is for a child to be seated therein. The alarming device20is configured to receive a signal and output an alarm signal. The detection mechanism30includes a detector31and a trigger mechanism33. The detector31is configured to detect whether states of the alarming device20and the detector31meet a predetermined criterion. The detector31is in a non-working state when the trigger mechanism33is in an open state, and the detector31is in a working state when the trigger mechanism33is in a closed state. When the child is seated in the child safety seat10, the driving portion40is operated to switch the trigger mechanism33from the open state to the closed state so as to switch the detector31to the working state. When the detector31detects that the states of the alarming device20and the detector31meet the predetermined criterion, the alarming device20outputs the alarm signal for alarming. The child safety seat10includes a base11and a seat body12. In an embodiment, the detection mechanism30and the driving portion40are disposed on the seat body12. However, the present invention is not limited thereto.

The predetermined criterion can be a predetermined distance. The detector31can be configured to detect a distance between the alarming device20and the detector31. For example, the predetermined distance can be set to 5 meters, and when the detector31detects that the distance between the alarming device20and the detector31is greater than 5 meters, the alarming device20can output the alarm signal for alarming. However, the present invention is not limited thereto. The predetermined distance can be set according to practical demands. Furthermore, the predetermined criterion can be a predetermined time. For example, when the detector31detects a period of that a driver leaves a car is greater than the predetermined time, the alarming device20can output the alarm signal for alarming. Therefore, the predetermined criterion is not limited to the aforementioned situation.

Moreover, the child safety seat alarm system further includes a sensing device, which is not shown in the figures, configured to sense a state of the child safety seat10and compare the state of the child safety seat10with a predetermined trigger criterion. When the state of the child safety seat10meets the predetermined trigger criterion, the child safety seat alarm system confirms that the child is seated in the child safety seat10. The sensing device can commonly include a pressure sensor or a gravity sensor. The predetermined trigger criterion can be that the child safety seat10receives a pressure or a buckle assembly of the child safety seat10is buckled. For example, a pressure value received by the child safety seat10can be detected by the pressure sensor, and when the detected pressure value is greater than a predetermined value, the child safety seat alarm system can determine that the child is seated in the child safety seat10. Furthermore, for example, when the buckle assembly of the child safety seat10is buckled, the child safety seat alarm system also can determine that the child is seated in the child safety seat10. Specifically, the child safety seat10includes a crotch strap and a crotch strap buckle assembly connected to the crotch strap, and buckling of a buckle assembly of the child safety seat10is achieved by buckling of the crotch strap buckle assembly. When the predetermined trigger criterion is met, the child safety seat alarm system confirms that the child is seated in the child safety seat10.

Please refer toFIG.3toFIG.4. The detection mechanism30is disposed on the child safety seat10. The driving portion40is connected to the crotch strap, and the buckling of the crotch strap buckle assembly drives the driving portion40to move to switch the trigger mechanism33to the closed state. In other words, when the crotch strap buckle assembly is buckled, the trigger mechanism33can be closed. The trigger mechanism33in the closed state can electrically conduct the alarming device20with the detector31to switch the alarming device20and the detector31to the working state. Furthermore, the driving portion40is rotatably connected to the child safety seat10. The crotch strap drives the driving portion40to rotate around the child safety seat10to switch the trigger mechanism33to the closed state. Specifically, the driving portion40includes a driving component41, a rotating component43connected to the driving component41and a pushing protrusion45disposed on the rotating component43. The rotating component43is rotatably connected to the child safety seat10. The driving component41is connected to the crotch strap. When the crotch strap buckle assembly is buckled, the driving component41is driven to rotate the rotating component43, so as to drive the pushing protrusion45to push the trigger mechanism33to switch to the closed state. In order to extend a service life of the driving portion40, the driving component41, the rotating component43and the pushing protrusion45can be integrally formed together. In a preferred embodiment, the pushing protrusion45can be an arc-shaped structure, as shown inFIG.7andFIG.8. Besides, the child safety seat alarm system further includes a resilient portion (not shown in the figures). The resilient portion drives the pushing protrusion45to move away from the trigger mechanism33. When the crotch strap buckle assembly is buckled, a resilient force of the resilient portion is overcome, so that the driving component41drives the rotating component43to rotate about the child safety seat10, and therefore, the pushing protrusion45drives the trigger mechanism33to be in the closed state.

Please refer toFIG.5. The detection mechanism30further includes a mounting plate35and a power source portion37. The power source portion37, the detector31, and the trigger mechanism33are disposed on the mounting plate35. The power source portion37is configured to provide electricity for the detector31. When the trigger mechanism33is in the open state, the power source portion37does not provide electricity for the detector31, and when the trigger mechanism33is in the closed state, the power source portion37provides electricity for the detector31. The detector31can be a distance measuring device which includes a signal processing unit and an emitting unit. Detailed description is omitted herein for simplicity. Furthermore, the trigger mechanism33includes a switch body331and a resilient contacting arm333. The resilient contacting arm333is disconnected from the switch body331to switch the trigger mechanism33to the open state. The resilient contacting arm333is pushed by the pushing protrusion45to abut against the switch body331, and therefore, the trigger mechanism33is switched to the closed state.

Please refer toFIG.6. The alarming device20can be an independent component. For example, the alarming device20includes a key chain21, so that the alarming device20can be connected with a car key of a user for the user to take the car key with the alarming device20. Besides, for example, the alarming device20can be installed on a mobile terminal of a user. Specifically, the mobile terminal can be a mobile phone, an IPAD, an in-car apparatus, an intelligent television, a card key, a smart key or any other electronic device which is capable of emitting sound and/or light and/or displaying images. In this embodiment, the mobile terminal is the mobile phone, and is capable of both receiving the signal transmitted from the detector31and outputting the alarm signal when a corresponding application software is installed in the mobile phone.

Please refer toFIG.9toFIG.10. The child safety seat alarm system further includes a linking component50, and the buckling of the crotch strap buckle assembly drives the driving portion40to move by the linking component50. For example, the linking component50can be a steel wire. After a male buckle and a female buckle are buckled, the driving portion40is driven by the linking component50to switch the trigger mechanism to the closed state. Specifically, in this embodiment, the trigger mechanism33is a switch connected to a wire60. An end of the wire60is connected to the detector31. The driving portion40drives the switch to be in the closed state or the open state, and therefore, the detector31is switched between the working state and the non-working state.

Please refer toFIG.11toFIG.13. In an embodiment, a crotch strap buckle assembly70includes a male buckle71and a female buckle72. Buckling of the crotch strap buckle assembly70is achieved by buckling of the male buckle71and the female buckle72, and the buckling of the male buckle71and the female buckle72drives the driving portion40to switch the detector31to the working state. The child safety seat alarm system further includes a power source circuit80. The detector31is disposed on the power source circuit80. A power source81is disposed on the power source circuit80for providing electricity for the detector31. Understandably, the power source81can be a power socket or a battery. Furthermore, the driving portion40can be a conductor. The driving portion40is disposed on the male buckle71. The power source circuit80, which can be electrically connected to the detector31, is disposed on the female buckle72. The buckling of the male buckle71and the female buckle72electrically connects the detector31with the power source circuit80by the driving portion40. Specifically, the power source circuit80is an open circuit, and the buckling of the male buckle71and the female buckle72electrically connects the conductor with the power source circuit80. That is, the buckling of the male buckle71and the female buckle72closes the power source circuit80by the conductor. As shown inFIG.11, the male buckle71includes a left male buckle711and a right male buckle713. The conductor is disposed on the left male buckle711and/or the right male buckle713. Detailed description is omitted herein for simplicity. Furthermore, the driving portion40also can be disposed on the female buckle72. The power source circuit80, which can be electrically connected to the detector31, is disposed on the male buckle71. By using the driving portion40, the buckling of the male buckle71and the female buckle72enables the detector31to be in electrical connection with the power source circuit80. Detailed description can be seen in the aforementioned description on the male buckle71, and therefore, is omitted herein for simplicity.

Please refer toFIG.1toFIG.13. The operation principle of the child safety seat alarm system is described as follows.

After the child is seated in the child safety seat10, the crotch strap buckle assembly can be buckled to drive the driving component41to rotate the rotating component43, so that the pushing protrusion45is driven by the rotating component43to switch the trigger mechanism33from the open state to the closed state. The trigger mechanism33in the closed state electrically connects the detector31with the power source portion37, and therefore, both the detector31and the alarming device20are in the working state. When the detector31detects that the distance between the alarming device20and the detector31is greater than the predetermined distance, the alarming device20outputs the alarm signal for alarming to remind the user that the child is left in a car.

In contrast to the prior art, when the child safety seat alarm system of the present invention confirms that the child is seated in the child safety seat10, the driving portion40is operated to switch the trigger mechanism33from the open state to the closed state so as to switch the detector31to the working state. Furthermore, when the detector31detects that the states of the alarming device20and the detector31meet the predetermined criterion, the alarming device20outputs the alarm signal for alarming to remind the user that the child is left in a car. This prevents a dangerous scenario where the child is left in the car.
