Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety, in particular to an automatic window opening circuit, a device and a vehicle. Background Art

[0002] When the vehicle is in motion, the windows and doors will automatically lock, which will prevent the occupants from escaping in time when an accident occurs. For example, when a spontaneous combustion occurs in the vehicle, but the occupants fail to find it in time and the windows remain closed, the occupants may suffer from carbon monoxide poisoning. When the vehicle falls into water, due to the high external water pressure, it is difficult for the occupants to open the doors and escape in time. It is difficult to avoid being injured by broken glass when escaping by breaking the windows. When the vehicle is hit and flipped, the windows are deformed and cannot be opened, or in the prior art, the windows are opened immediately when a collision is detected, causing the occupants to be thrown out of the windows when the vehicle flips. All of the above situations will prevent the occupants from escaping in time, endangering personal safety.

[0003] At the same time, the existing automatic window opening device is connected to the main circuit of the car. When an accident occurs in the car, the circuit inside the car will inevitably be damaged, causing the automatic window opening device to lose its function. After the car is accidentally flooded, the circuit may short-circuit and fail; the window cannot be lowered, and the door is difficult to open after the water reaches a certain depth, resulting in people being unable to escape in time. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the vehicle windows cannot be opened automatically and reliably under various accidents, thereby providing an automatic window opening circuit, device and vehicle.

[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] When a vehicle is hit during driving and rolls over, the doors are squeezed or deformed and cannot be opened, and the windows are easily deformed, making it impossible for people inside the car to open them manually and escape in time; and when the vehicle falls into water, the water pressure outside the car makes it impossible to open the windows manually, endangering the lives of people inside the car.

[0034] This embodiment provides an automatic window opening circuit 1, such as Figure 1 As shown, it is arranged in a vehicle, and the automatic window opening circuit includes: a water falling detection switch 11, a collision sensor switch 12, a smoke sensor switch 13, an intermediate relay 15, a lifter assembly switch 16 and a carbon monoxide sensor switch 14.

[0035] like Figure 1 As shown, the water fall detection switch 11 has a first end connected to the power supply, and a second end connected to the first end of the intermediate relay 15; the collision sensor 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 sensor switch 13 has a first end connected to the power supply, and a second end connected to the second end of the intermediate relay 15; the carbon monoxide sensor 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.

[0036] Specifically, Figure 1In the embodiment, the water-fall detection switch 11 has a built-in water level monitoring device. When the water level monitoring device detects that the water level is too high, it determines that the vehicle has fallen into the water, and the water-fall detection switch 11 is turned on, so that the intermediate relay 15 is energized; the collision sensor switch 12 has a built-in collision monitoring device. When the collision monitoring device detects a strong collision, it determines that the vehicle has a serious collision. The collision sensor switch 12 is turned on, so that the intermediate relay 15 is energized; the smoke sensor switch 13 has a built-in multiple smoke concentration monitoring devices. When any smoke concentration monitoring device detects that the concentration of the smoke is too high, it determines that spontaneous combustion has occurred in the vehicle. The smoke sensor switch 13 is turned on, so that the intermediate relay 15 is energized; the carbon monoxide sensor switch 14 is used to turn on when it is determined that the carbon monoxide concentration in the vehicle exceeds a preset range, so that the intermediate relay 15 is energized. After the intermediate relay 15 is energized, it can drive the subsequent circuit to drive the escape mechanism in the vehicle to automatically operate, so as to facilitate the timely escape of the people in the vehicle.

[0037] It should be noted that those skilled in the art may also add other types of gas sensor switches to ensure the safety of occupants in the vehicle, such as a carbon dioxide sensor switch, a nitric oxide sensor switch, etc., to control the intermediate relay 15 to be energized when the corresponding gas concentration exceeds the standard.

[0038] like Figure 1 As shown, the lifter assembly switch 16 has a power supply end connected to the third end of the intermediate relay 15, a control end connected to the fourth end of the intermediate relay 15, a first output end connected to the central lock in the vehicle, and a second output end connected to all the windows (#1~#n) in the vehicle.

[0039] Specifically, Figure 1 In the embodiment, the lifter assembly switch 16 is connected to the central lock and all the windows respectively. When the central lock is in the closed state, the occupants cannot control the lifting of the windows; when any one or more of the water fall detection switch 11, the collision sensor switch 12, and the smoke sensor switch 13 are turned on and the relay is energized, it indicates that a serious accident has occurred in the vehicle and the windows need to be unlocked and controlled to be lowered to help the occupants escape. At this time, the lifter assembly switch 16 releases the locking state of the central lock and makes the locking state of the central lock invalid and maintains the unlocking state. At the same time, the lifter assembly switch 16 controls the lowering of all the windows and turns off the rising function of all the windows, so as to facilitate the timely escape of the occupants.

[0040] It should be noted that the second output end of the intermediate relay can also be connected to the central locking of all vehicle doors, so that when an accident occurs, all vehicle doors are actively unlocked without waiting for the driver's unlocking command, thereby increasing the escape speed.

[0041] The automatic window opening circuit provided in this embodiment can automatically open all windows in the event of various accidents such as when the vehicle falls into water, collides, when harmful gases in the vehicle exceed the standard, or when spontaneous combustion occurs in the vehicle, so as to prevent the doors and windows from being deformed and unable to be opened, or when the water pressure outside the vehicle is high and the windows cannot be opened when the vehicle falls into water, so as to facilitate the timely escape of the people in the vehicle. The automatic window opening circuit of this embodiment can simultaneously monitor the occurrence of various accidents of the vehicle, respond in time, and reliably open the windows in various accidents. The circuit has high reliability and ensures the personal safety of the people in the vehicle.

[0042] In some optional embodiments, such as Figure 2 As shown, the water fall detection switch 11 includes: a water level sensor 111 and a water level switch 112, wherein the water level sensor 111 has a first end connected to a power supply, and a second end connected to a first end of the water level switch 112; the water level switch 112 has a second end connected to a first end of an intermediate relay 15. When the water level sensor 111 detects that the water level in the vehicle exceeds a preset water level, the water level sensor 111 controls the water level switch 112 to turn on.

[0043] Optionally, the water fall detection switch can also be a buoyancy switch, whose first end is connected to the power supply and whose second end is connected to the first end of the intermediate relay, and is used to be turned on when the water level in the vehicle exceeds a preset water level, so that the intermediate relay is energized. The float in the buoyancy switch floats on the water surface. When the water level changes, the buoyancy of the float also changes, driving the switch contacts connected to it to operate. When the water level exceeds the preset water level, the buoyancy of the float reaches a threshold, causing the buoyancy switch to be turned on and the intermediate relay 15 to be energized. Preferably, Figure 2 In the figure, 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. It does not directly contact the liquid and is not affected by the viscosity, surface tension or other physical properties of the liquid. It has a long service life, a wide detection range, high sensitivity and a fast response speed.

[0044] In some optional embodiments, such as Figure 2 As shown, the collision sensor switch 12 includes: a collision sensor 121 and a collision switch 122, wherein the first end of the collision sensor 21 is connected to the power supply, and the second end of the collision sensor 21 is connected to the first end of the collision switch 122; the second end of the collision switch 122 is connected to the first end of the intermediate relay 15. When the collision sensor 121 detects that the vehicle has collided, the collision sensor 121 controls the collision switch 122 to be turned on.

[0045] Optionally, Figure 2 In the embodiment, the collision sensing switch 12 is a thyristor structure, which can be turned on for a long time and maintain permanent power supply.

[0046] Optionally, Figure 2In the embodiment, the collision sensor 121 can be a mechanical collision sensor such as a rolling ball type, a roller type, an eccentric ball type, etc., which realizes the conduction and interruption of the circuit through the 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 such as a roller type and an eccentric ball type, which detects the intensity of the collision through electronic signals. Compared with mechanical sensors, electronic sensors have higher sensitivity and accuracy.

[0047] In some optional embodiments, such as Figure 2 As shown, the smoke sensor switch 13 includes: a smoke sensor 131 and a smoke switch 132, wherein the smoke sensor 131 has a first end connected to a power source, and a second end connected to a first end of the smoke switch 132; the smoke switch 132 has a second end connected to a second end of the intermediate relay 15. 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 turn on.

[0048] Optionally, Figure 2 In the embodiment, the gas sensor switch and the smoke sensor switch 13 can also be connected in parallel to detect the concentration of harmful gases such as carbon monoxide. When the carbon monoxide concentration in the car is too high, the people in the car cannot find it in time, which endangers personal safety. The gas sensor switch will be turned on, so that the window is opened to allow air circulation.

[0049] In some optional embodiments, such as Figure 2 As shown, the automatic window opening circuit 1 also includes: a mercury switch 17, a first end of which is connected to the power supply, and a second end of which is connected to the first end of the intermediate relay 15, which is used to be turned on when the inclination angle of the vehicle to the reference horizontal plane is greater than a preset angle, so that the intermediate relay 15 is energized.

[0050] It should be noted that, since the mercury switch is sealed, the mercury inside is isolated from the outside world, so it can be used in harsh environmental conditions such as oil, steam, dust and corrosive gas. In addition, 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 slight external force is applied to tilt the mercury switch, the mercury can move, making the mercury switch on and off.

[0051] In some optional embodiments, such as Figure 3 As shown, the automatic window opening circuit 1 also includes: a time relay 18, a first end of which is connected to the second end of the water fall detection switch 11, and a second end of which is connected to the first end of the intermediate relay 15. When one or more of the water fall detection switch 11, the collision sensor switch 12, and the mercury switch 6 are turned on, it is powered on and turned on after a preset delay, so that the intermediate relay 15 is powered on.

[0052] Specifically, Figure 3In the embodiment, when a serious collision occurs in a vehicle and causes the vehicle to roll over, if the collision sensor switch 12 directly controls the intermediate relay 15 to be energized after detecting the accident, the windows will be directly opened during the rolling process of the vehicle, causing the occupants to be thrown out of the vehicle, seriously endangering their personal safety; therefore, a time relay 18 is set, which is turned on when the collision sensor switch 12 detects that the vehicle has rolled over. At this time, the time relay 18 is not turned on within the delay time. When the delay time is reached, and the mercury switch 17 determines that the vehicle maintains a rollover state, a rollover into water state, or a back-up water state, and the mercury no longer moves violently, it indicates that the vehicle is no longer rolling and the occupants will not be thrown out, then the time relay 18 is turned on, the intermediate relay 15 is energized and turned on, and all the windows are opened.

[0053] Specifically, Figure 3 When the vehicle passes through deep water, the high water level will trigger the water-fall detection switch 11 to turn on. At this time, the time relay 18 slowly closes within the preset delay time. During the preset delay time, if the water-fall detection switch 11 detects that the vehicle has left the deep water area, the water-fall detection switch 11 is disconnected, and the time relay 18 is reset, maintaining the disconnected state to avoid triggering the intermediate relay 15 to turn on, thereby preventing the windows of the vehicle from opening by mistake when passing through the deep water area.

[0054] Specifically, Figure 4 The specific circuit diagram of the automatic window opening circuit is shown in FIG. After disconnecting the line between the negative pole output line of the power supply and the negative pole input line of the lift assembly switch 16 of the vehicle cab, the negative end of the power supply is connected to the water fall detection switch 11, the collision sensor switch 12, and the mercury switch 17, and then connected to the intermediate relay through the time relay 18. After that, the normally closed end of the intermediate relay 15 is connected to the negative pole input line of the lift assembly switch 16 of the vehicle cab. The common end of the intermediate relay 15 is connected to the negative pole of the power supply, and the normally open end of the intermediate relay 15 is connected to the negative pole line connection line between each window lifter and the lift motor and the central lock connection line through the lift assembly switch 16.

[0055] Specifically, Figure 4 In normal circumstances, after the negative power supply line of the lifter assembly switch 16 is disconnected, it is connected to the common end of the intermediate relay 15, and then the power is directly supplied to the cut negative power supply line end of the lifter assembly switch 16 through the normally closed end of the intermediate relay 15. This does not affect the original line function, and when a vehicle failure causes the intermediate relay 15 to be energized, automatic window opening and unlocking can be achieved; if the accident has not been resolved, the negative power supply line of the lifter assembly switch 16 has been cut off, or in the event of a malfunction, the occupants can also manually open the windows and unlock them.

[0056] Specifically, Figure 4In the circuit, when the intermediate relay 15 is in the normally closed state, the window lifter functions normally and the central locking function maintains the original state; when the intermediate relay 15 is turned on, the normally open end is energized to trigger automatic unlocking of the central locking and automatic window opening. At this time, the window raising function fails and the central locking closing function fails, and the occupants cannot control the window closing. When the window closing button is forcibly pressed, the circuit power supply is in the cut-off state, so there will be no short circuit, so that the window can be reliably opened in various accidents of the vehicle. The circuit has high reliability and ensures the personal safety of the occupants.

[0057] It should be noted that the positive power supply line of the lifter assembly switch 16 can also be disconnected and then connected to the common end of the intermediate relay 15, and then power can be directly supplied to the cut positive power supply line end of the lifter assembly switch 16 through the normally closed end of the intermediate relay 15, so as to achieve the effect that the occupants of the vehicle cannot control the closing of the windows in the event of a fault.

[0058] This embodiment provides an automatic window opening device, such as Figure 5 As shown, it is arranged in a vehicle, and the automatic window opening device includes: a protective cover 2, a partition 3, a circuit board 4 and the automatic window opening circuit 1 of the above embodiments and any optional implementation manner thereof, wherein a time relay 18 and an intermediate relay 15 are integrated on the circuit board 4, and a water drop detection switch 11, a collision sensor switch 12, a smoke sensor switch 13, a time relay 18, an intermediate relay 15 and a mercury switch 17 are all electrically connected through the circuit board 4 and then electrically connected to a lifter assembly switch 16 outside the protective cover 2; a plurality of air inlets are provided on the top of the protective cover 2, and the smoke sensor switch 13 is fixedly mounted on the top of the protective cover 2; the partition 3 is fixed in the protective cover 2 to divide the protective cover into an upper space and a lower space, and the circuit board 4 is fixedly connected to the upper surface of the partition 3; the mercury switch 17 is invertedly mounted in the space below the partition 3; and the water drop detection switch 11 is mounted in the space below the partition 3.

[0059] Optionally, a mesh cover 5 and a dustproof sponge 6 are provided on the outside of the water fall detection switch 11 ; the dustproof sponge 6 is used for filtering dust; and the mesh cover 5 is used for supporting the dustproof sponge 6 .

[0060] Optionally, the partition is connected to the water-fall detection switch 11, the mesh cover 5 and the dust-proof sponge 6 by waterproof sealant, and the carbon monoxide sensor can be arranged together with the smoke sensor switch 13. The mercury switch 17 cooperates with the water level sensor or the micro switch and the float device to realize that the window can be opened and the lock can be opened automatically after the vehicle falls into water at any angle. A transparent sealing cover can be arranged outside the water-fall detection switch 11 to protect the surface of the water-fall detection switch 11 from being clean, thereby improving the recognition ability of the non-contact sensor.

[0061] The automatic window opening device provided in this embodiment, the relay and sensor switch in the automatic window opening circuit are all arranged in a protective cover, which isolates dust and water vapor, maintains the sensitivity of the sensor, and ensures that all windows are automatically opened in various accidents such as when the vehicle falls into water, hits, when harmful gases in the vehicle exceed the standard, or when spontaneous combustion occurs in the vehicle, so as to avoid deformation of doors and windows that cannot be opened, or when the water pressure outside the vehicle is high and the windows cannot be opened when falling into water, so as to facilitate timely escape of people in the vehicle. The automatic window opening circuit of the utility model can monitor the occurrence of various accidents of the vehicle at the same time, respond in time, and can reliably open the windows in various accidents. The circuit has high reliability and ensures the personal safety of people in the vehicle.

[0062] This embodiment provides a vehicle, including: a vehicle body and an automatic window opening device according to the above embodiments and any optional implementation manner thereof. The control principle of the automatic window opening device is the same as the above content and will not be repeated here.

[0063] The vehicle provided in this embodiment has the function of automatically opening all windows in the event of various accidents such as when the vehicle falls into water, collides, when harmful gases in the vehicle exceed the standard, or when spontaneous combustion occurs in the vehicle, so as to prevent the doors and windows from being deformed and unable to be opened, or when the water pressure outside the vehicle is high and the windows cannot be opened when the vehicle falls into water, so as to facilitate the timely escape of the people in the vehicle. The automatic window opening circuit of the utility model can simultaneously monitor the occurrence of various accidents of the vehicle, respond in time, and reliably open the windows in various accidents.
