[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0035] When the vehicle is overturned due to a collision during driving, the door is pressed or deformed and cannot be opened, and the window is also deformed to cause the vehicle occupants to be unable to manually open the window, so that they cannot escape in time. When the vehicle falls into water, the water pressure outside the vehicle causes the window to be unable to be manually opened, endangering the lives of the vehicle occupants. Therefore,

[0036] The present embodiment provides an automatic window opening circuit 1, as shown in FIG. 1, which is arranged in a vehicle. The automatic window opening circuit includes a water falling detection switch 11, a collision sensing switch 12, a smoke sensing switch 13, an intermediate relay 15, a lifter assembly switch 16, and a carbon monoxide sensing switch 14.

[0037] As shown in FIG. 1, the water falling detection switch 11 has a first end connected to a power supply and a second end connected to a first end of the intermediate relay 15. The collision sensing switch 12 has a first end connected to the power supply and a second end connected to the first end of the intermediate relay 15. The smoke sensing switch 13 has a first end connected to the power supply and a second end connected to a second end of the intermediate relay 15. The carbon monoxide sensing switch 14 has a first end connected to the power supply and a second end connected to the second end of the intermediate relay 15.

[0038] Specifically, in FIG. 1, the water falling detection switch 11 is internally provided with a water level monitoring device. When the water level monitoring device detects that the water level is too high, it is determined that the vehicle has fallen into water, the water falling detection switch 11 is turned on, and the intermediate relay 15 is powered. The collision sensing switch 12 is internally provided with a collision monitoring device. When the collision monitoring device detects a strong impact, it is determined that the vehicle has a serious collision, the collision sensing switch 12 is turned on, and the intermediate relay 15 is powered. The smoke sensing switch 13 is internally provided with a plurality of smoke concentration monitoring devices. When any of the smoke concentration monitoring devices detects that the concentration of the smoke is too high, it is determined that a fire has occurred in the vehicle, the smoke sensing switch 13 is turned on, and the intermediate relay 15 is powered. The carbon monoxide sensing switch 14 is used to turn on when it is determined that the carbon monoxide concentration in the vehicle exceeds the preset range, so that the intermediate relay 15 is powered. After the intermediate relay 15 is powered, the rear circuit can be driven to automatically actuate the escape mechanism in the vehicle, so that the vehicle occupants can escape in time.

[0039] It should be noted that the skilled person in the art can also add other types of gas sensor switches to ensure the safety of the vehicle occupants, such as carbon dioxide sensor switches, nitric oxide sensor switches, etc., to control the power of the intermediate relay 15 when the corresponding gas concentration exceeds the standard.

[0040] As shown in Fig. 1, the lifter assembly switch 16 is connected with the third end of the intermediate relay 15 at the power supply end, connected with the fourth end of the intermediate relay 15 at the control end, connected with the central locking of the vehicle at the first output end, and connected with all the vehicle windows (#1~#n) in the vehicle at the second output end.

[0041] Specifically, in Fig. 1, the lifter assembly switch 16 is connected with the central locking and all the vehicle windows respectively. When the central locking is in the closed state, the people in the vehicle cannot control the vehicle window to lift. When any one or more of the falling water detection switch 11, the collision sensing switch 12, and the smoke sensing switch 13 are turned on, the relay is powered, which indicates that the vehicle has a serious accident at this time, and the vehicle window needs to be unlocked and controlled to descend to help the people in the vehicle escape. At this time, the lifter assembly switch 16 releases the locking state of the central locking and makes the central locking locking state invalid, maintains the unlocking state, and then controls all the vehicle windows to descend while closing the rising function of all the vehicle windows, which facilitates the people in the vehicle to escape in time.

[0042] It should be noted that the second output end of the intermediate relay can also be connected with the central locking of all the vehicle doors, so that all the vehicle doors are actively unlocked when an accident occurs, without waiting for the unlocking instruction of the driver, thereby improving the escape speed.

[0043] The automatic window opening circuit provided by the embodiment can automatically open all the vehicle windows when the vehicle falls into water, collides, the harmful gas in the vehicle exceeds the standard, or the vehicle is self-ignited, etc., so as to avoid the deformation of the vehicle door and the vehicle window, which cannot be opened, or the water pressure outside the vehicle is large when falling into water, which causes the vehicle window to be unable to be opened, and facilitates the people in the vehicle to escape in time. The automatic window opening circuit of the embodiment can simultaneously monitor the occurrence of various accidents of the vehicle, respond in time, reliably open the window under various accidents, has high circuit reliability, and protects the personal safety of the people in the vehicle.

[0044] In some optional embodiments, as shown in Fig. 2, the falling water detection switch 11 includes a water level sensor 111 and a water level switch 112, wherein the first end of the water level sensor 111 is connected with the power supply, and the second end is connected with the first end of the water level switch 112; the second end of the water level switch 112 is connected with the first end of the intermediate relay 15. When the water level sensor 111 detects that the water level in the vehicle exceeds the preset water level, the water level sensor 111 controls the water level switch 112 to be turned on.

[0045] Optionally, the water-falling detection switch can also be a float switch, the first end of which is connected with the power supply, and the second end of which is connected with the first end of the intermediate relay, and which is used to be turned on when the water level in the vehicle exceeds a preset water level, so that the intermediate relay is powered on. In the float switch, a floating ball floats on the water surface, and when the water level changes, the buoyancy acting on the floating ball also changes, driving the switch contact connected therewith to act. When the water level exceeds the preset water level, the buoyancy acting on the floating ball reaches a threshold, causing the float switch to be turned on and the intermediate relay 15 to be powered on. Optionally, in FIG. 2, the water level sensor 111 is a non-contact water level sensor, such as an ultrasonic water level sensor, a radar water level sensor, a photoelectric water level sensor, etc., which does not directly contact the liquid and is not affected by the viscosity, surface tension or other physical properties of the liquid, has a long service life, a wide detection range, high sensitivity and fast response speed.

[0046] In some optional embodiments, as shown in FIG. 2, the collision sensing switch 12 includes a collision sensor 121 and a collision switch 122, wherein the collision sensor 121, the first end of which is connected with the power supply, and the second end of which is connected with the first end of the collision switch 122; the collision switch 122, the second end of which is connected with the first end of the intermediate relay 15, and when the collision sensor 121 detects that the vehicle is hit, the collision sensor 121 controls the collision switch 122 to be turned on.

[0047] Optionally, in FIG. 2, the collision sensing switch 12 is of a silicon-controlled structure, which can be turned on for a long time and maintain permanent power-on.

[0048] Optionally, in FIG. 2, the collision sensor 121 can be a mechanical collision sensor of a rolling ball type, a rolling roller type, an eccentric ball type, etc., which realizes the turn-on and interruption of the circuit through an internal mechanical structure, and its working state depends on the acceleration of the vehicle in the collision. The collision sensor 121 can also be an electronic collision sensor of a rolling roller type and an eccentric ball type, etc., which detects the strength of the collision through an electronic signal. Compared with the mechanical sensor, the electronic sensor has higher sensitivity and accuracy.

[0049] In some optional embodiments, as shown in FIG. 2, the smoke sensing switch 13 includes a smoke sensor 131 and a smoke switch 132, wherein the smoke sensor 131, the first end of which is connected with the power supply, and the second end of which is connected with the first end of the smoke switch 132; the smoke switch 132, the second end of which is connected with the second end of the intermediate relay 15, and when the smoke sensor 131 detects that the smoke concentration in the vehicle exceeds a preset concentration, the smoke sensor 131 controls the smoke switch 132 to be turned on.

[0050] Optionally, in Fig. 2, a gas sensing switch can also be connected in parallel with the smoke sensing switch 13 for detecting the concentration of harmful gases such as carbon monoxide. When the concentration of carbon monoxide in the vehicle is too high, the people inside the vehicle cannot find it in time and it is harmful to personal safety. The gas sensing switch will be turned on, so that the vehicle window is opened to make the air circulate.

[0051] In some optional embodiments, as shown in Fig. 2, the automatic window opening circuit 1 further comprises a mercury switch 17, the first end of which is connected with the power supply, and the second end of which is connected with the first end of the intermediate relay 15, for turning on when the inclination angle of the vehicle with the reference horizontal plane is greater than the preset angle, so that the intermediate relay 15 is powered.

[0052] It should be noted that since the mercury switch is sealed, the internal mercury is isolated from the outside world, so it can be used in harsh environmental conditions such as oil, steam, dust and corrosive gases. And mercury is the only metal that can remain liquid at room temperature. Its surface tension and specific gravity are both large. As long as a little external force is applied to make the mercury switch tilt, the mercury can move, so that the mercury switch is turned on and off.

[0053] In some optional embodiments, as shown in Fig. 3, the automatic window opening circuit 1 further comprises a time relay 18, the first end of which is connected with the second end of the water detection switch 11, and the second end of which is connected with the first end of the intermediate relay 15, for being powered when one or more of the water detection switch 11, the collision sensing switch 12 and the mercury switch 17 are turned on, and being turned on after a preset time delay, so that the intermediate relay 15 is powered.

[0054] Specifically, in Fig. 3, when the vehicle is in a serious collision and rolls over, if the collision sensing switch 12 directly controls the intermediate relay 15 to be powered after detecting the accident, it will cause the vehicle window to be opened directly during the rolling process of the vehicle, which will seriously endanger the safety of the people inside the vehicle. Therefore, a time relay 18 is provided, which is turned on when the collision sensing switch 12 detects that the vehicle is rolling over. At this time, the time relay 18 is still in the delay time and has not been turned on. When the delay time arrives, and the mercury switch 17 determines that the vehicle is in a side-rolling state, a side-rolling water state or an upside-down water state, and the mercury no longer moves violently, it indicates that the vehicle is no longer rolling and the people inside the vehicle will not be thrown out. Therefore, the time relay 18 is turned on, the intermediate relay 15 is powered and turned on, and all the vehicle windows are opened.

[0055] Specifically, in FIG. 3, when the vehicle drives through the deep water level, the water level triggers the water-falling detection switch 11 to be turned on, at this time, the time relay 18 slowly absorbs within the preset delay time; within the preset delay time, if the water-falling detection switch 11 detects that the vehicle drives out of the deep water area, the water-falling detection switch 11 is turned off, the time relay 18 is reset, the off state is maintained to avoid triggering the intermediate relay 15 to be turned on, and to avoid the vehicle window to be opened by mistake during the vehicle driving through the deep water area.

[0056] Specifically, FIG. 4 is a specific circuit diagram of the automatic window opening circuit. After disconnecting the line between the negative pole of the power supply and the power negative pole input line of the lifter assembly switch 16 of the vehicle cab, connecting the negative pole of the power supply with the water-falling detection switch 11, the collision sensing switch 12, the mercury switch 17, connecting through the time relay 18 and the intermediate relay, then connecting the normally closed end of the intermediate relay 15 with the power negative pole input line of the lifter assembly switch 16 of the vehicle cab. The common end of the intermediate relay 15 is connected with the negative pole of the power supply, and the normally open end of the intermediate relay 15 is connected with the negative pole line connection between each vehicle window lifter and the lifting motor and the central locking connection line through the lifter assembly switch 16.

[0057] Specifically, in FIG. 4, under normal circumstances, after disconnecting the negative pole power input line of the lifter assembly switch 16 and connecting the common end of the intermediate relay 15, the normally closed end of the intermediate relay 15 directly supplies power to the cut-off negative pole input line of the lifter assembly switch 16, so that the original line function is not affected, and the automatic window opening and unlocking can be realized when the intermediate relay 15 is powered due to vehicle failure; in the case of no accident removal, the negative pole input line of the lifter assembly switch 16 has been cut off, or in the case of malfunction, the vehicle occupants can also manually open the window and unlock the central lock.

[0058] Specifically, in FIG. 4, when the intermediate relay 15 is normally closed, the lifter function of the vehicle window is normal, and the central lock function maintains the original state unchanged; when the intermediate relay 15 is turned on, the normally open end supplies power to trigger the automatic unlocking of the central lock and the automatic opening of the window, at this time, the window lifting function is invalid, the central lock closing function is invalid, and the vehicle occupants cannot control the window closing, the circuit power supply is in a cut-off state when the window closing button is forced to be pressed, so that short circuit does not occur, reliable window opening can be realized in various vehicle accidents, the circuit reliability is high, and the personal safety of the vehicle occupants is ensured.

[0059] It should be noted that the positive pole power input line of the lifter assembly switch 16 can also be disconnected, the common end of the intermediate relay 15 is connected, and the normally closed end of the intermediate relay 15 is directly powered to the cut-off positive pole input line of the lifter assembly switch 16, so that the effect that the vehicle occupants cannot control the window closing in case of failure is realized.

[0060] The embodiment provides an automatic window opening device, as shown in Figure 5, which is arranged in a vehicle, and the automatic window opening device comprises a protective cover 2, a partition plate 3, a circuit board 4 and the automatic window opening circuit 1 in the above embodiment and any optional implementation manner thereof, wherein the time relay 18 and the intermediate relay 15 are integrated on the circuit board 4, the falling water detection switch 11, the collision sensing switch 12, the smoke sensing switch 13, the time relay 18, the intermediate relay 15 and the mercury switch 17 are electrically connected through the circuit board 4 and then electrically connected with the lifter assembly switch 16 outside the protective cover 2; a plurality of air inlets are formed in the top of the protective cover 2, and the smoke sensing switch 13 is fixedly installed on the top in the protective cover 2; the partition plate 3 is fixed in the protective cover 2 to divide the protective cover into two spaces, the upper space and the lower space, the circuit board 4 is fixedly connected with the upper surface of the partition plate 3; the mercury switch 17 is installed in the lower space of the partition plate 3 in an inverted manner; and the falling water detection switch 11 is installed in the lower space of the partition plate 3.
