[0002] A child safety seat is a seat designed specifically for children. By assembling the child safety seat in a vehicle, a child can sit on the child safety seat, and the child is restrained by the child safety seat to ensure the safety of the child.

[0003] Among them, the lower part of the child safety seat is usually fixed to the vehicle seat by isofix, and the upper part is connected to the corresponding interface of the vehicle through a top tether with a buckle structure. However, when an installer assembles the child safety seat in a vehicle, sometimes the following two situations may occur: (1) After connecting and locking the isofix at the lower part of the child safety seat to the vehicle seat, forgetting to connect and lock the top tether of the child safety seat to the vehicle; (2) After connecting and locking the top tether of the child safety seat to the vehicle, forgetting to connect and lock the isofix at the lower part of the child safety seat to the vehicle seat. The above two situations both mean that the child safety seat is not fully and correctly assembled in the vehicle, which will pose a safety hazard to the child during the ride.

[0004] Therefore, there is an urgent need for an assembly system reminder device that can remind of incorrect incomplete assembly and a child safety seat with such a device. Summary of the Invention

Preferably, the power supply 312 can be a battery installed on the chair body 201, but it is not limited thereto. The battery can be selected as a mobile power supply 312 according to actual needs, or a directly externally connected external power supply 312, such as the power supply 312 provided by a car; one end of the main circuit 31 is electrically connected to the first end switch of the first trigger switch 21, the second end of the first trigger switch 21 is electrically connected to the first end of the first circuit 32, the other end of the main circuit 31 is electrically connected to the first end of the second trigger switch 22, and the second end of the second trigger switch 22 is electrically connected to the first end of the second circuit 33. At this time, both the first mounting member 11 and the second mounting member 12 are in the idle position, and the first mounting member 11 and the second mounting member 12 do not install the chair body 201 of the child safety seat 200 to the corresponding mounting position. The main circuit 31, the first circuit 32, and the second circuit 33 form an open circuit, forming a circuit in an open state as shown in Figure 2 . The alarm device 311 is not powered on and does not alarm, and does not remind the user; when the first mounting member 11 is in the mounting position and the second mounting member 12 is in the idle position, the first mounting member 11 triggers the second end of the first trigger switch 21 to disconnect from the first circuit 32 and be electrically connected to the second end of the second circuit 33, so that the main circuit 31 and the second circuit 33 are connected in series and form a closed circuit, forming a circuit in a closed state as shown in Figure 3 . As a result, the alarm device 311 is powered on and alarms, reminding the user that the second mounting member 12 has not been connected to the vehicle, that is, reminding the user that the assembly is not completely correct; or, when the second mounting member 12 is in the mounting position and the first mounting member 11 is in the idle position, the second mounting member 12 triggers the second end of the second trigger switch 22 to disconnect from the second circuit 33 and be electrically connected to the second end of the first circuit 32, so that the main circuit 31 and the first circuit 32 are connected in series and form a closed circuit, forming a circuit in a closed state as shown in Figure 4 . As a result, the alarm device 311 is powered on and alarms, reminding the user that the first mounting member 11 has not been connected to the vehicle, that is, reminding the user that the assembly is not completely correct. When both the first mounting member 11 and the second mounting member 12 are in the mounting position, that is, when both the first mounting member 11 and the second mounting member 12 install the chair body 201 of the child safety seat 200 to the corresponding mounting position, the main circuit 31, the first circuit 32, and the second circuit 33 form an open circuit, forming a circuit in an open state as shown in Figure 5 . The alarm device 311 is not powered on and does not alarm.

[0043] Please refer to Figures 6 to 8, in the second embodiment of the assembly system reminder device 100 of the present invention, on the basis of the first embodiment, the assembly system reminder device 100 further includes a third trigger switch 23, a third circuit 34, a fourth circuit 35, and a third mounting member 13 for mounting the seat body 201 in the vehicle. The first end of the third trigger switch 23 is electrically connected to the second circuit 33. The first ends of the third circuit 34 and the fourth circuit 35 are respectively electrically connected to the first circuit 32. A first diode 341 is provided on the third circuit 34, and a second diode 351 is provided on the fourth circuit 35. The current conduction direction of the first diode 341 is opposite to the current conduction direction of the second diode 351. The third mounting member 13 also has a mounting position and an idle position relative to the seat body 201. Only when the first mounting member 11, the second mounting member 12, and the third mounting member 13 are all mounted to the corresponding mounting positions, the seat body 201 of the child safety seat 200 is completely assembled in the vehicle. Among them, the third mounting member 13 is a abutting member or an anchoring member. The abutting member is a ground contact indicator or an anti-collision top rod of the vehicle safety seat. The anchoring member is a top tether, an ISOFIX fixing member, or a soft belt fixing member. In this embodiment, the third mounting member 13 is an ISOFIX fixing member, but not limited thereto. The third mounting member 13 may also be a top tether, a ground contact indicator, an anti-collision top rod of the vehicle safety seat, or a soft belt fixing member, etc. When the first mounting member 11, the second mounting member 12, and the third mounting member 13 are all in the idle position, the second end of the third trigger switch 23 is electrically connected to the second end of the third circuit 34, and the first diode 341 is in a cut-off state, forming a circuit structure as shown in Figure 6 . Among them, the forward current of the power supply 312 flows from the main circuit 31 through the first trigger switch 21 into the first circuit 32. Since the first diode 341 does not conduct current and is in a cut-off state, and the second circuit 33 is disconnected from the first circuit 32, the circuit structure is open, and the alarm device 311 is not powered on and does not alarm, without reminding the user. When the third mounting member 13 is in the mounting position and the first mounting member 11 and the second mounting member 12 are in the idle position, the third mounting member 13 triggers the second end of the third trigger switch 23 to be electrically connected to the second end of the fourth circuit 35, and the second diode 351 is in a conducting state, forming a circuit structure as shown in Figure 7For the circuit structure shown, since the current conduction directions of the first diode 341 and the second diode 351 are opposite, when the forward current of the power supply 312 flows from the main line 31 through the first trigger switch 21 into the first line 32, it can pass through the second diode 351 and flow from the fourth line 35 into the second line 33, and finally flow into the main line 31 through the second trigger switch 22, forming a circuit path, enabling the alarm device 311 to be powered on and alarm, reminding the user that the first mounting member 11 and the second mounting member 12 are not yet connected to the vehicle, that is, reminding the user that the assembly is not completely correct. It can be understood that in this second embodiment, as long as one or both of the first mounting member 11, the second mounting member 12, and the third mounting member 13 are mounted to the corresponding mounting positions, a circuit path will be formed, causing the alarm device 311 to alarm and be powered on; when all three of the first mounting member 11, the second mounting member 12, and the third mounting member 13 are mounted to the corresponding mounting positions or all three are in the idle positions, that is, when all three of the first mounting member 11, the second mounting member 12, and the third mounting member 13 are assembled or not in the vehicle, the circuit is not conducting, and the alarm device 311 does not need to alarm.

[0044] Please refer to Figure 1 、 Figure 9 and Figure 10, for facilitating the disconnection of the second end of the first trigger switch 21 from the first line 32 and the electrical connection to the second end of the second line 33 by the first mounting member 11, a first driving unit is provided between the first mounting member 11 and the first trigger switch 21. By the first mounting member 11 moving to the mounting position and driving the first driving unit to act, the first driving unit triggers the disconnection of the second end of the first trigger switch 21 from the first line 32 and the electrical connection to the second end of the second line 33. In this embodiment, the first driving unit includes a first driving member 41, the first driving member 41 is pivotally connected to the chair body 201, the first mounting member 11 is arranged on the first driving member 41, and the first mounting member 11 drives the first driving member 41 to rotate, so that the first driving member 41 pushes and triggers the first trigger switch 21. When the first mounting member 11 disengages from the mounting position and resets to the idle position, in order to enable the first trigger switch 21 to disconnect from the second line 33 and reconnect to the first line 32 electrically, that is, to reset the first trigger switch 21, the first driving unit further includes an elastic member 42 for resetting the first driving member 41. The elastic member 42 is arranged between the first driving member 41 and the chair body 201. When the first mounting member 11 moves from the idle position to the mounting position, it will drive the first driving member 41 to rotate. The first driving member 41 compresses the elastic member 42 and pushes the first trigger switch 21. When the first mounting member 11 moves from the mounting position to the idle position, the first driving member 41 is pushed and reset under the elastic restoring force of the elastic member 42. The second end of the first trigger switch 21 resets and reconnects to the first line 32 again after losing the pushing force of the first driving member 41. Among them, the first trigger switch 21 can adopt an elastic switch, and the elastic member 42 can adopt an existing compression spring, etc.

[0045] Please refer to Figure 1 , Figures 11 to 14 , a second driving unit is provided between the second mounting member 12 and the second trigger switch 22. By the second mounting member 12 moving to the mounting position and driving the second driving unit to act, the second driving unit triggers the disconnection of the second end of the second trigger switch 22 from the second line 33 and the electrical connection to the second end of the first line 32. In this embodiment, the second driving unit includes a release lock member 51 and a second driving member 52. The release lock member 51 is placed on the second mounting member 12, and the second driving member 52 is fixedly connected to the release lock member 51.

Among them, the second trigger switch 22 can adopt an elastic switch, and the release lock member 51 adopts a release lock button, but it is not limited thereto.

[0046] In summary, since the child safety seat 200 of the present invention is provided with an assembly system reminder device 100, when the first mounting member 11 is in the mounting position and the second mounting member 12 is in the idle position, the second end of the first mounting member 11 triggers the disconnection of the second end of the first trigger switch 21 from the first line 32 and is electrically connected to the second end of the second line 33, so that the main line 31 and the second line 33 are connected in series to form an electrical circuit path, thereby energizing the alarm device 311 to alarm, reminding the user that the second mounting member 12 has not been connected to the vehicle, that is, reminding the user that the assembly is not completely correct; when the second mounting member 12 is in the mounting position and the first mounting member 11 is in the idle position, the second mounting member 12 triggers the disconnection of the second trigger switch 22 from the second line 33 and is electrically connected to the second end of the first line 32, so that the main line 31 and the first line 32 are connected in series to form an electrical circuit path, thereby energizing the alarm device 311 to alarm, reminding the user that the first mounting member 11 has not been connected to the vehicle, that is, reminding the user that the assembly is not completely correct; when both the first mounting member 11 and the second mounting member 12 are in the mounting position or the idle position, that is, when both the first mounting member 11 and the second mounting member 12 are assembled or not in the vehicle, the main line 31, the first line 32 and the second line 33 form an open circuit, and the alarm device 311 is not energized and does not alarm.
