Detailed ways

The safety device provided by the present invention is used in a car, so that when the temperature of the compartment reaches a certain high temperature, the windows of the vehicle can be opened automatically to allow air convection to reduce the temperature of the compartment. Instead, the invention applies to a sealable car or bus or similar means of transport with electric windows.

Please refer to Fig. 1, shows the constituent unit of a preferred embodiment of the present invention, comprises: a power supply 10; A control circuit 12, is connected with this power supply 10; The control circuit 12 is used to transmit signals to the control circuit. The power supply 10 is also connected with a window motor 16 and a fan 18 of the vehicle.

The power source 10 can be the power source of the car itself, that is, the battery of the car; it can also be an external battery installed in the car, for example, in the engine room or other appropriate locations.

The thermal chip 14 can sense the temperature in the environment, and transmit the temperature information to the control circuit 12 as an electronic signal. When the temperature reaches a set value, the control circuit starts the power supply of the window motor 16 to control the lift of the window.

The present invention installs the heat-sensitive chip 14 in the compartment, such as in the interior of the compartment, or in the instrument panel, or under the seat, so as to detect the temperature in the compartment. The control circuit 12 can receive the temperature information detected by the thermal chip 14 to determine whether to activate the electric motor of the window.

When the temperature in the airtight compartment reaches a certain temperature, such as 35°C, when the control circuit receives the message that the compartment temperature reaches this temperature, it will turn on the power supply 10 and start the window motor 16 to make the window glass of the car 20 22 decline, as shown in Figure 2, the air in the compartment can be convected with the outside world, so the temperature of the compartment can be effectively reduced.

In practice, the window motor can be used to fully open the window, or as shown in Figure 2, only open an appropriate gap, such as 5 cm, so that others cannot put their hands into the compartment and open the door. A limit switch (limit switch) can be installed in the trajectory of the window glass lift to control the opening gap of the window.

The safety device also includes an activation temperature and a shutdown temperature. The start-up temperature is the set temperature value for opening the vehicle window, such as the aforementioned 35°C. The closing temperature is the set temperature value for closing the vehicle window.

When the compartment is ventilated and the temperature in the compartment drops to the closing temperature, such as 26°C, the thermal chip 14 transmits the temperature information to the control circuit 12, and the control circuit starts the power supply 10 to make the window motor 16 drive the window The glass rises to close the windows.

After the windows are opened, in addition to the air convection that can lower the cabin temperature, if it rains, the temperature inside the car will drop to the closing temperature within a short period of time, so that the windows will be closed to prevent rainwater from flowing into the car.

The activation temperature and shutdown temperature can be shown in Figure 4, built in the thermal chip 14, when the temperature detected by the thermal chip reaches the startup temperature or the shutdown temperature, the thermal chip will transmit a signal to the control Circuits to generate the action of opening or closing the windows respectively.

On the contrary, please refer to FIG. 5 , the startup temperature and shutdown temperature can also be constructed in the circuit of the control circuit 12 . In this way, the heat-sensitive chip 14 continuously transmits the temperature information of the compartment to the control circuit, and when the temperature signal reaches the set value of the starting temperature or closing temperature, the control circuit will only generate the action of opening or closing the window. move.

Regardless of whether the values of the two temperatures (starting temperature and closing temperature) are built into the thermal chip 14 or the control circuit 12, they can be a constant value and cannot be adjusted by the user. Preferably, the values of the two temperatures can be set by the user, please refer to Fig. 4 and Fig. 5, so that the user can set it through a setter 25 or 25'.

Also, referring to Fig. 5, the present invention can establish a timing unit 26 in the control circuit 12, and start timing from the opening of the window, after a period of timing, such as 3 minutes, the temperature in the compartment does not significantly drop, or Have not dropped to closing temperature, this safety device promptly can agitate aforementioned fan 18 and carry out forced ventilation.

The fan 18 can be an external fan installed in the vehicle to agitate the air in the compartment. Preferably, a fan of the vehicle itself can be used as the fan 18 . Please refer to Fig. 2, the car all has a cold air or heating pipeline, and its air outlet is communicated with compartment, and blows gas with fan 18. Usually, the cold air pipeline is the pipeline for exchanging air between the compartment and the outside world. Therefore, through the blowing of the fan 18 and using the pipeline, as shown in FIG. 2, the outside air can be sucked into the compartment, or, as shown in FIG. 3, the fan can be reversed to discharge the hot air in the compartment to the outside. . In this way, the ventilation speed of the compartment is accelerated, and the cooling of the compartment is accelerated.

After the temperature drops to the shutdown temperature, the control circuit 12 stops the operation of the fan 18 . Preferably, the timing time of the timing unit 26 can also be set by the user.

It should be noted that, in practice, the fan can be started simultaneously when the window is opened, and it is not necessary to provide a timing unit.

The invention makes the windows of the car lower automatically when the air in the compartment reaches a high temperature, so that the compartment is no longer airtight and the temperature in the compartment is lowered, so as to prevent the danger of children being forgotten in the compartment due to negligence, and can reduce the risk of accidents in the compartment. Generation of toxic gases. After the window is opened, in addition to generating air convection, the child can call for help through the open window, so that others can hear and rescue. Therefore, the present invention can improve the safety of automobile use.

To sum up, the present invention utilizes a reasonable and effective technical means to achieve practical effects, which is in line with the elements of the invention patent, and the application is filed according to law.
