Abstract

A safety device for controlling ventilation of a vehicle compartment. The safety device is mounted in a vehicle with electric windows, including: a power supply connected with a motor for driving the electric window; a controlling circuit connected with the power supply; and a thermal sensor disposed in the compartment of the vehicle and connected with the controlling circuit. The thermal sensor serves to sense the temperature in the compartment and transmit signals to the controlling circuit. In the case that the temperature in the compartment reaches a certain value, the controlling circuit powers on the power supply to activate the motor for opening the window. Therefore, the compartment is ventilated and the temperature of the compartment can be lowered.

Claims

1. A safety device for controlling ventilation of a vehicle compartment, the safety device being mounted in a vehicle with electric windows, the safety device comprising:

a power supply installed in the vehicle and connected with a window motor of the vehicle;

a controlling circuit connected with the power supply; and

a thermal sensor disposed in the compartment of the vehicle and connected with the controlling circuit, the thermal sensor serving to sense the temperature in the compartment and transmit signals to the controlling circuit, whereby in the case that the temperature reaches a certain value, the controlling circuit powers on the power supply to activate the window motor for opening the window.

2. The safety device as claimed in claim 1, wherein a value of an activation temperature is preset in the safety device, whereby when the temperature of the compartment reaches the activation temperature, the controlling circuit activates the motor to open the window.

3. The safety device as claimed in claim 2, wherein the value of the activation temperature is preset in the thermal sensor, whereby when the temperature of the compartment reaches the activation temperature, the thermal sensor transmits a signal to the controlling circuit.

4. The safety device as claimed in claim 2, wherein the value of the activation temperature is preset in the controlling circuit.

5. The safety device as claimed in claim 3, further comprising a setter for setting the value of the activation temperature.

6. The safety device as claimed in claim 4, further comprising a setter for setting the value of the activation temperature.

7. The safety device as claimed in claim 2, wherein a value of a closing temperature is preset in the safety device, whereby when the temperature of the compartment is lowered from the activation temperature to the closing temperature, the controlling circuit activates the motor to close the window.

8. The safety device as claimed in claim 7, wherein the value of the closing temperature is preset in the thermal sensor, whereby when the temperature of the compartment reaches the closing temperature, the thermal sensor transmits a signal to the controlling circuit.

9. The safety device as claimed in claim 7, wherein the value of the closing temperature is preset in the controlling circuit.

10. The safety device as claimed in claim 8, further comprising a setter for setting the value of the closing temperature.

11. The safety device as claimed in claim 9, further comprising a setter for setting the value of the closing temperature.

12. The safety device as claimed in claim 1, further comprising a fan disposed in the vehicle and connected with the power supply for blowing air into the compartment or exhausting the air out of the compartment;

the controlling circuit serving to power on the power supply for operating the fan.

13. The safety device as claimed in claim 12, wherein the controlling circuit includes a timer unit, whereby when the window is opened, the timer unit starts timing and after a period of time, the controlling circuit activates the fan.

14. The safety device as claimed in claim 13, wherein the timing duration of the timer unit is resettable.

15. The safety device as claimed in claim 1, wherein the power supply is a battery of the vehicle.

16. The safety device as claimed in claim 12, wherein the fan is a fan of air-conditioner pipeline of the vehicle.
