Drawings

Fig. 1 is a schematic block diagram of a life support device in the door opening warning system according to the present invention.

Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Referring to fig. 1, a life support device in a door opening warning system according to a preferred embodiment of the present invention is installed on an automobile, and is used for unlocking a door after the door is locked by the door opening warning system in an emergency event of the automobile, so as to prevent people in the automobile from being trapped in the automobile and causing tragedy.

The life support device in the early warning system that opens door includes control module 1, with control module 1 signal connection's lock module 3 and sensor module 2, lock module 3 has the characteristics of delaying inefficiency height, prevents the mistake unblock. The sensor module 2 at least includes a first sensor 21, a second sensor 22 and a third sensor 23, the first sensor 21 is used for detecting the acting force applied to the door handle of the automobile by the external force, the second sensor 22 is used for detecting whether water enters the automobile, and the third sensor 23 is used for detecting whether the temperature in the automobile is increased. Indeed, in other embodiments, the sensor module 2 may also include others, which are not specifically limited herein, according to the actual situation. The control module 1 is a microcomputer and the like, can receive signals sent by a plurality of sensors at the same time and can process the signals in parallel; the door lock module 3 is a door lock on a vehicle door, and is not particularly limited herein, depending on the actual situation.

Specifically, the first sensor 21 is a pressure sensor 21, and the pressure sensor 21 is mounted on a door handle of an automobile. During installation, the door handle needs to be ensured to work normally. When a person strongly presses or drags the door handle, pressure is applied to the pressure sensor 21, and then the pressure sensor 21 detects the force value; alternatively, the occupant drags the door handle twice in succession to apply pressure to the pressure sensor 21, and the pressure sensor 21 detects the force value. An acting force threshold is preset in the control module 1, and the acting force threshold is determined according to the actual situation and is not specifically limited herein. The pressure sensor 21 detects an action force value and sends the action force value to the control module 1, the control module 1 compares the action force value with an action force threshold value, and if the action force value is within the action force threshold value, the control module 1 controls the door lock module 3 to unlock. Indeed, in other embodiments, when the vehicle occupant encounters a sudden disaster, the door opening warning system fails to lock the vehicle door, and the vehicle occupant may drag the door handle several times to apply pressure to the pressure sensor 21, so that the pressure sensor 21 detects the force value. At this time, the control module 1 is preset with an emergency acting force threshold, and the comparison method is as described above and will not be described herein. Accordingly, the range of the emergency force threshold depends on the actual situation.

The second sensor 22 is a water sensor 22, and the water sensor 22 is used for detecting whether water enters the vehicle. In order to ensure the correctness of the detection result, the water sensor 22 may be installed at the trunk and/or the hood of the vehicle, and indeed, in other embodiments, the water sensor 22 may also be installed at other positions of the vehicle, which is not specifically limited herein, depending on the actual situation. In this embodiment, the water sensor 22 is a contact water sensor 22. The contact water sensor 22 uses the principle of liquid conduction for detection. In normal conditions, the probes at the two poles are insulated by air, and in a water immersion state, the probe of the contact type water immersion sensor 22 is conducted, and the sensor outputs a dry contact signal. When the probe is immersed in water to a height of about 1 mm, an alarm signal is generated. Indeed, in other embodiments, the water sensor 22 may be a non-contact water sensor 22, which is not limited herein and depends on the actual situation.

The third sensor 23 is a temperature sensor 23, the temperature sensor 23 is used for quickly responding when a fire breaks out in the automobile, and the temperature sensor 23 detects the temperature in the automobile in real time and outputs the temperature in real time. A temperature threshold is preset in the control module 1, and the temperature threshold is determined according to actual conditions and is not specifically limited herein. When a fire disaster occurs to the automobile, the temperature sensor 23 detects a temperature value and sends the temperature value to the control module 1, the control module 1 compares the temperature value with the temperature threshold value, and if the temperature value is in the temperature threshold value, the control module 1 controls the door lock module 3 to unlock.

In order to ensure the accuracy of the detection results of the pressure sensor 21, the water sensor 22 and the temperature sensor 23, the pressure sensor 21, the water sensor 22 and the pressure sensor 21 have a false identification verification mechanism to prevent errors. Correspondingly, the control module 1 and the door lock module 3 are also provided with a redundancy check mechanism to prevent misoperation.

The above process is as follows: the sensor module 2 is used for detecting the sudden change of the environment to obtain a sudden change signal, and sends the sudden change signal to the control module 1, the control module 1 receives the sudden change signal to control the unlocking of the door lock module 3, the unlocking is convenient and fast, and the safety of personnel in the vehicle is improved.

The life support device in the early warning system that opens door still includes and is used for considering as power module 5 of control module 1, sensor module 2 and the power supply of lock module 3, this power module 5 supplies power for life support device alone to prevent when whole car system became invalid and falls the electricity, life support device can't normally operate. In the present embodiment, the power module 5 is a battery assembly. Indeed, in other embodiments, the power module 5 may be other, and is not limited herein, depending on the actual situation.

The life support device in the door opening early warning system also comprises an alarm module 4 in signal connection with the control module 1; when the control module 1 receives the mutation signal, the alarm module 4 is started. In this embodiment, the alarm module 4 is a buzzer and/or an indicator light. Indeed, in other embodiments, the alarm module 4 may be other, and is not specifically limited herein, depending on the actual situation.
