When a child is riding on the child seat 10, the drive unit 40 can be operated to convert the trigger structure 33 from an off state to an on state, and after the drive unit 40 is operated to drive the trigger structure 33 to turn on, when the detection device 31 detects that the states of both the alarm device 20 and the detection device 31 meet the preset condition, the alarm device 20 outputs an alarm signal to issue an alarm. The child seat 10 includes a base 11 and a seat body 12, and in one embodiment, the detection mechanism 30 and the driving unit 40 are installed on the seat body 12, but are not limited thereto.

[0030] Here, the preset condition is a certain distance, and the detection device 31 detects the distance between the alarm device 20 and the detection device 31. For example, if the certain distance is 5 meters and the detection device 31 detects that the distance between the alarm device 20 and the detection device 31 is greater than 5 meters, the alarm device 20 outputs an alarm signal to issue an alarm, but is not limited thereto, and the value of the certain distance can be set according to the actual situation. Of course, the preset condition may be a certain time, and if the detection device 31 detects that the driver has been away from the vehicle for a period exceeding the certain time, the alarm device 20 outputs an alarm signal to issue an alarm. Therefore, there is no limitation on the preset condition.

[0031] The child seat alarm system further includes a detection device (not shown) that detects the state of the child seat 10 and compares it with a preset trigger condition. If the state of the child seat 10 meets the preset trigger condition, it is confirmed that a child is seated in the child seat. The detection device may be a normal pressure sensor, a gravity sensor, or the like. The preset trigger condition is the pressure applied to the child seat 10 or the engagement of the buckle of the child seat 10. For example, a pressure sensor is used to detect the pressure value applied to the child seat 10, and if this pressure value is greater than a predetermined value, it is determined that a child is seated in the child seat 10. In addition, for example, it is also possible to determine that a child is seated in the child seat 10 by the engagement of the buckle of the child seat 10. Specifically, the child seat 10 includes a belt and a belt buckle that connects the belt, and the buckle of the child seat 10 is engaged by the engagement of the belt buckle.

[0036] 11-13, in one embodiment, the belt buckle 70 includes a male buckle 71 and a female buckle 72, and the male buckle 71 and the female buckle 72 are engaged to realize the engagement of the belt buckle 70, and the engagement of the male buckle 71 and the female buckle 72 operates the driving unit 40 and the detection device 31 is in an operating state. The child seat alarm system further includes a power supply circuit 80, the detection device 31 is mounted on the power supply circuit 80, and a power supply 81 is further mounted on the power supply circuit 80 for providing power to the detection device 31, and it should be understood that the power supply 81 can be a power socket or a battery. Furthermore, the driving unit 40 is a conductor, the driving unit 40 is mounted on the male buckle 71, and the power supply circuit 80 is mounted on the female buckle 72, which can be electrically connected to the detection device 31, and the male buckle 71 and the female buckle 72 are engaged, and the detection device 31 and the power supply circuit 80 are electrically connected by the driving unit 40. Specifically, the power supply circuit 80 has an open structure, and the male buckle 71 and the female buckle 72 are engaged to electrically connect the conductor to the power supply circuit 80. That is, the male buckle 71 and the female buckle 72 are engaged to close the power supply circuit 80 by the conductor. For example, as shown in FIG. 11, the male buckle 71 includes a left male buckle 711 and a right male buckle 713, and the conductor is installed in either the left male buckle 711 and / or the right male buckle 713, but this will be omitted here. Of course, the driving unit 40 can be installed on the female buckle 72, and the power supply circuit 80 capable of being electrically connected to the detection device 31 can be installed on the male buckle, and the male buckle 71 and the female buckle 72 can be engaged to electrically connect the detection device 31 to the power supply circuit 80 by the driving unit 40. However, since the description of the male buckle 71 can be referred to for details, this will be omitted here.

[0037] The operating principle of the child seat alarm system of the present invention will be described below with reference to FIGS.

[0038] After a child is seated in the child seat 10, the belt buckle of the belt is engaged, which causes the rotating member 43 to rotate in conjunction with the driving member 41, driving the pushing protrusion 45 to press the trigger structure 33, converting the trigger structure 33, which was in the off state, to the on state. When the trigger structure 33 is closed (turned on), the detection device 31 and the power supply unit 37 are electrically connected and enter an operating state, the detection device 31 and the alarm device 20 enter an operating state, and when the detection device 31 detects that the distance between the alarm device 20 and the detection device 31 is greater than a predetermined value, the alarm device 20 outputs an alarm signal to sound an alarm, alerting the user that there is a child in the vehicle.

[0039] Compared with the prior art, in the child seat alarm system of the present invention, when it is confirmed that a child is seated in the child seat 10, the drive unit 40 is operated, the trigger structure 33 is driven and converted from an off state to an on state, and the detection device 31 is put into an operating state. When the detection device 31 detects that the states of both the alarm device 20 and the detection device 31 satisfy the preset condition, the detection device 31 sends a signal to the alarm device 20, the alarm device 20 receives the signal and outputs an alarm signal to issue an alarm, thereby alerting the user that a child is in the car, and preventing the child from being left in the car and being in danger.
