judging whether the supporting legs are correctly installed or not according to the height signal of the headrest and the angle signal of the supporting legs, and if not, displaying a third warning signal;
and displaying a corresponding detection result on the touch display panel according to the detection result.
The safety seat for children is characterized in that the crocodile mouth is arranged on the safety seat for children and used for being connected with a seat connecting device of a vehicle, a control switch is arranged at the joint of the seat back and the base, and the crocodile mouth is not closed, the supporting legs are closed, and the headrest is located at an initial position in an initial state.
It should be noted that, in a typical vehicle, a total of 3 fixing devices are provided for 2 ISOFIX interfaces (i.e., the seat connecting device in the present invention) on the back and the LATCH interface on the top. Placing a seat on a back row seat, releasing three fixing pieces (namely crocodile mouths) of the seat for standby, and connecting the bottom 2 ISOFIX interfaces with the left and right ISOFIX interfaces of the seat; after ISOFIX is connected, the seat needs to be pressed downwards by the physical force, and the ISOFIX connecting belt is tightened to firmly fix the seat on the vehicle; and after the ISOFIX interface is fixed, taking out the LATCH interface at the top, connecting the LATCH interface with the special vehicle-mounted LATCH interface, and tightening the connecting belt, namely finishing the installation.
Since the user may not be very skilled in the installation of the safety seat, the present invention prompts the user through the display of several detection signals, which, in case of receiving a power supply signal,
if the alligator is connected with the seat connecting device, triggering an alligator closing signal;
if the control switch is not triggered, the base is judged to be not installed in place.
In this embodiment, since the child safety seat is in a state where the alligator is not closed, the support leg is retracted, and the headrest is in the initial position when the child safety seat leaves the factory, when the consumer starts to install the seat, that is, the state of the alligator is closed and the state of the support leg are changed, in order to achieve a false alarm caused by going from the unpowered state to the powered state, the alarm determination logic shown in fig. 1 is detailed as shown in fig. 4, where:
when the seat is just electrified, the state of the seat can be detected firstly, if the alligator is not closed (no alligator closing signal), the supporting leg is not unfolded (the supporting leg angle signal judges that the supporting leg is in a contraction state), the seat control switch is triggered (a steering detection signal comprises a forward direction and a reverse direction), and the state can not trigger an alarm when the self-detection is carried out. And when the requirement of the preset condition is met, the child seat enters the formal installation adjustment detection (the preset condition can be preset time after self-detection or trigger a corresponding button or trigger some other condition to control the child seat to enter the formal installation adjustment stage).
When the headrest height signal judges that the headrest is within the preset height, if any crocodile mouth is not closed (not receiving all crocodile mouth closing signals) or the supporting leg is in a contraction state (judging that the supporting leg is in the contraction state by the supporting leg angle signal) or the seat is not installed in place (not receiving a steering detection signal), triggering an alarm, and carrying out corresponding display on the touch control display panel according to a corresponding warning signal;
when the headrest is judged to be out of the preset height by the headrest height signal, at the moment, if any crocodile mouth is not closed (all crocodile mouth closing signals are not received) or the supporting leg is in an unfolded state (the supporting leg is judged to be in the unfolded state by the supporting leg angle signal) or the seat is not installed in place (the steering detection signal is not received) or the seat is installed reversely (the seat is judged to be reversely installed by the steering detection signal), at the moment, the alarm is triggered, and the corresponding display is carried out on the touch control display panel according to the corresponding warning signal.
It should be noted that, in this embodiment, the safety seat is provided with two ISOFX interfaces, a complete alligator closing signal is triggered only after the two ISOFX interfaces (that is, the alligator) at the rear row of the vehicle are connected to the two ISOFX interfaces on the child seat, and when only one or none of the ISOFX interfaces is connected, it is determined that the alligator is not closed, and the first warning signal is triggered.
For the positive and negative judgment of the chair back, if the chair back does not face to the positive and negative directions or the reverse direction, the chair back is in a free state at the moment, and a second warning signal is directly sent. Because the influence of the height that children are different, if the height is too high, if the back of the chair orientation is anti, then must influence children's the seat and experience, consequently, if the headrest height is more than predetermineeing the height and the back of the chair orientation is anti then report to the police, triggers the second warning signal, otherwise does not report to the police.
Whether the supporting legs are installed correctly, because different height requirements of children on the safety seat are considered, whether the supporting legs are closed or not is selected through the height of the headrest in the embodiment, in the upward adjustment process of the headrest, the travel switch is arranged in the chair back, the travel switch is in an off state when the headrest is at the initial position, in the upward pulling adjustment process of the headrest, if the headrest is pulled up to the preset height (set according to design requirements), the travel switch is triggered, and the fact that the headrest reaches the preset height is judged.
The method comprises the following steps that a mode below a preset height is a mode 01, a mode above the preset height is a mode 23, and the mode 01 is applicable to children with short heights and the mode 23 is applicable to children with high heights, so that the seat needs to be higher in the mode 01 to enable the children to have enough sitting heights, and the supporting legs need to be completely opened at the moment (in the embodiment, the supporting legs and the seat are in a completely opened state at 90 degrees, and corresponding signals are triggered by the combination of the supporting legs and the base in the completely opened state to judge); on the contrary, in the '23 mode', only the height is required to be lower, and at the moment, the supporting legs only need to be kept in a closed state. And when the supporting leg does not match the height of the headrest, a third warning signal is displayed.
The first warning signal, the second warning signal and the third warning signal are displayed on the touch control display panel through image indicator lamps at corresponding error positions and accompanied by warning sounds (as shown in figure 1), after the first preset time is reached, the warning sounds are stopped no matter whether the installation meets the requirements or not, but the warning lamps are kept in a lighting state, and when the indicator lamps reach the second preset time, the indicator lamps are turned off. The warning is stopped within the set time, so that the condition that the posture of the seat is incorrect after the seat is adjusted due to the fact that the child safety seat does not need to be used under certain special conditions but needs to be adjusted correspondingly is met.
In this example, the power supply signal includes a self-power supply signal (power supply signal such as a storage battery and a battery) and a vehicle power supply signal (a cigarette lighter, a vehicle-mounted USB power supply signal, etc.), and the seat is provided with additional functional modules, such as a heating module, a ventilation module, a seat back adjuster, a pressure sensor, and a communication module, as shown in fig. 3, where:
when the power supply signal is a self-power supply signal, the heating module, the ventilation module and the chair back regulator are in a closed state (and a power indicator lamp cannot be turned on), when the pressure sensor triggers a sensing signal, the communication module is started, and information such as real-time electric quantity and the like is sent to a user side (electric quantity data is sent once at intervals of 10% of electric quantity, and an early warning signal is sent to the user side when the electric quantity is lower than a preset value);
when the power supply signal is a vehicle power supply signal, the heating module, the ventilation module, the chair back regulator and the communication module are in an enabling state (a user needs to touch the corresponding power supply key for a third preset time to enable, and simultaneously lights up the power supply indicator lamp, and then turns off the additional function module and turns off the power supply indicator lamp when touching the power supply key again for the third preset time), and the heating module, the ventilation module and the chair back regulator can be regulated through the touch display panel or sending a regulating signal to the communication module through the user side.
After the vehicle-mounted power supply equipment is inserted, a user needs to touch the power supply icon on the touch display panel for a third preset time, the vehicle-mounted power supply equipment is powered on, and the corresponding power supply icon is lightened. Under the power supply state of the vehicle, all functions of the safety seat can be used, the user side can adjust the functional modules through the communication module, and the communication module feeds back corresponding data to the user side and displays the data. And when receiving a key corresponding to the corresponding additional function module on the touch display panel, starting the additional function module, and adjusting the gear of the corresponding additional function module according to the touch times. (in this embodiment, the heating module and the ventilation module are respectively provided with three gears, one gear is touched for starting, two gears are touched for two times, three gears are touched for three times, four times of stopping are performed, the cycle is repeated, the additional function module can be adjusted according to the instruction signal of the mobile phone end of the user, the working time of the additional function module can be set, and the two touch buttons corresponding to the chair back adjuster can realize the up-and-down adjustment of the chair back only by continuously touching the corresponding ascending or descending buttons)
And under self-powered state, the functions of chair back regulation, ventilation and heating are all in the shut-down state, and the power indicator lamp keeps the off state, can't start through user side and touch display panel, and simultaneously, when the electric quantity is less than the default, sends electric quantity early warning signal to the user side. Through two power supply modes, under the self-powered condition, the use authority of part of functional modules is locked, and real-time electric quantity information (including related data information of other various child safety seats) is sent to a user side after a child sits on the seat, so that the use time under the self-powered state is prolonged, and under the vehicle power supply state, all the functional modules are opened, and better sitting experience is provided for the child.
Meanwhile, as shown in fig. 3, when the user is flamed out from the car, the pressure sensor senses whether a child is left in the car, and if the child is left in the car and the user leaves a preset distance, the user side receives the voice warning signal from the communication module. And when the pressure sensor stops triggering the induction signal for a preset time, controlling the safety seat to enter a low-power mode. Through the operation, the children stay in the car to be reminded intelligently, and meanwhile, the children can timely enter the low-power-consumption mode when finishing sitting and riding, so that the power consumption in the self-power-supply mode is further reduced.
