[0025] The present invention brings at least the following beneficial effects:

[0026] The present invention provides an emergency controller, comprising: an outer cover, a handle and a controller assembly, wherein the handle is connected to the controller assembly, and the outer cover is provided on the handle and the controller assembly; the controller assembly comprises a sensor, a gas separator and a rotator, wherein the gas separator is provided between the sensor and the rotator, and the handle is connected to the sensor via the rotator; the sensor comprises a sensor box and a sensor element, a first micro switch and a second micro switch installed on the sensor box, the rotator is connected to the sensor element, the first micro switch is connected in series to a first circuit, the second micro switch is connected in series to a second circuit, and the sensor element can control the first micro switch and the second micro switch to be turned on or off; the gas separator comprises a gas separator body and a sensor element connected to the gas separator The rotator comprises a rotator body and a first air channel and a second air channel arranged on the rotator body; under a normal state, the sensor element disconnects the first micro switch and the second micro switch, and the first air channel and the second air channel connect the air channel connectors to form a ventilation circuit; when the handle is rotated to a first emergency state, the sensor element turns on the first micro switch and the second micro switch, and the first air channel and the second air channel disconnect the ventilation circuit; when the handle is rotated to a second emergency state, the sensor element turns on the first micro switch and the second micro switch, and the first air channel and the second air channel connect the air channel connectors to form an exhaust circuit.

[0027] Under normal conditions, the sensor element disconnects both the first and second microswitches. The first microswitch is connected in series to the first circuit, preventing the alarm connector in the first circuit from operating. The second microswitch is connected in series to the second circuit, preventing the solenoid valve coil in the second circuit from operating. The first and second airways connect the airway connectors to form a ventilation circuit, allowing the airway and door pump to operate normally.

[0028] When the emergency controller is needed, the handle is first rotated a certain angle to reach the first emergency state. Since the handle is connected to the sensor element via a rotator, the sensor element will rotate synchronously to turn on the first microswitch and the second microswitch. At this time, the alarm connector set in the first circuit is activated due to the conduction of the first microswitch, and the alarm is turned on and sounds an alarm. The solenoid valve coil set in the second circuit is activated due to the conduction of the second microswitch, and the solenoid valve coil is turned on, allowing the passenger door to open. The rotator also rotates to disconnect the ventilation circuit between the first and second airways, thereby cutting off the air path of the passenger door.

[0029] Then, continue rotating the handle in the same direction through a certain angle to reach the second emergency state. The sensor element will rotate synchronously to connect the first microswitch and disconnect the second microswitch. At this time, the alarm connector set in the first circuit continues to operate due to the conduction of the first microswitch, and the alarm is turned on and continues to sound. The solenoid valve coil set in the second circuit stops operating due to the disconnection of the second microswitch. The rotator will rotate until the first and second air channels connect the air circuit connectors to form an exhaust circuit, through which the remaining gas inside is discharged to ensure safe use. At this time, if the passenger door is not open, it can be pushed open by hand. To restore, rotate the handle in the opposite direction to the initial angle.

[0030] The structure and operation of the emergency controller described above demonstrate its overall simplicity, enabling universal installation within existing vehicle structures without altering the existing vehicle framework. The controller utilizes a minimal number of transitional components, operates in a simple principle, and eliminates the need for specialized transitional decorative molds, resulting in low R&D and installation costs. During operation, the alarm and air circuits achieve synchronized emergency control, effectively ensuring passenger safety.

[0059] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0060] Example 1

[0061] The existing emergency controller has a complex structure, many transition assembly parts, and a complex principle of emergency control. It cannot be directly installed, maintained, and used according to the existing vehicle layout. It requires the development of special transition decoration molds and the addition of decorative parts, which results in high R&D and installation costs.

[0062] In view of this, an embodiment of the present invention provides an emergency controller, comprising: an outer cover 100, a handle 200 and a controller assembly, wherein the handle 200 is connected to the controller assembly, and the outer cover 100 is provided to cover the handle 200 and the controller assembly; Figure 1The controller assembly includes a sensor 310, a gas separator 320 and a rotator 330. The gas separator 320 is arranged between the sensor 310 and the rotator 330, and the handle 200 is connected to the sensor 310 through the rotator 330; the sensor 310 includes a sensor box 311 and a sensor element, a first micro switch 313 and a second micro switch 314 installed on the sensor box 311, the rotator 330 is connected to the sensor element, the first micro switch 313 is connected in series on the first circuit 315, and the second micro switch 314 is connected in series on the second circuit 316. The sensor element can control the first micro switch 313 and the second micro switch 314 to be turned on or off; the gas separator 320 includes a gas separator body 321 and a plurality of gas path connectors connected to the gas separator body 321, and the plurality of gas path connectors are connected to the two The two are not connected to each other; the rotator 330 includes a rotator body 331 and a first air channel 332 and a second air channel 338 arranged on the rotator body 331; in a normal state, the sensor element disconnects the first micro switch 313 and the second micro switch 314, and the first air channel 332 and the second air channel 338 connect the air path connector to form a ventilation circuit; when the handle 200 is rotated to a first emergency state, the sensor element turns on the first micro switch 313 and the second micro switch 314, and the first air channel 332 and the second air channel 338 disconnect the ventilation circuit; when the handle 200 is rotated to a second emergency state, the sensor element turns on the first micro switch 313 and the second micro switch 314, and the first air channel 332 and the second air channel 338 connect the air path connector to form an exhaust circuit.

[0063] Under normal conditions, the sensor element disconnects both the first microswitch 313 and the second microswitch 314. The first microswitch 313 is connected in series to the first circuit 315. The disconnection of the first microswitch 313 prevents the alarm connector 3151 provided in the first circuit 315 from operating. The second microswitch 314 is connected in series to the second circuit 316. The disconnection of the second microswitch 314 prevents the solenoid valve coil 3161 provided in the second circuit 316 from operating. The first airway 332 and the second airway 338 connect the airway connectors to form a ventilation circuit, allowing the airway and the door pump to operate normally.

[0064] To use the emergency control, the handle 200 is first rotated a certain angle to reach the first emergency state. Since the handle 200 is connected to the sensor via the rotator 330, the sensor rotates synchronously to turn on the first microswitch 313 and the second microswitch 314. At this time, the alarm connector 3151 provided in the first circuit 315 is activated due to the conduction of the first microswitch 313, and the alarm is turned on and sounds an alarm. The solenoid valve coil 3161 provided in the second circuit 316 is activated due to the conduction of the second microswitch 314, and the solenoid valve coil 3161 is turned on, opening the passenger door. The rotator 330 also rotates to disconnect the first airway 332 and the second airway 338, thereby disconnecting the ventilation circuit and cutting off the air path of the passenger door.

[0065] Then, continue rotating the handle 200 in the same direction through a certain angle to reach the second emergency state. The sensor element will synchronously rotate to connect the first microswitch 313 and disconnect the second microswitch 314. At this time, the alarm connector 3151 provided in the first circuit 315 continues to operate due to the conduction of the first microswitch 313, and the alarm is turned on and continues to sound. The solenoid valve coil 3161 provided in the second circuit 316 stops operating due to the disconnection of the second microswitch 314. The rotator 330 will rotate until the first air channel 332 and the second air channel 338 connect the air channel connectors to form an exhaust circuit. The exhaust circuit exhausts the remaining gas inside, ensuring safe use. At this point, if the passenger door is not open, it can be opened manually. To restore the door, rotate the handle 200 in the opposite direction to the initial angle.

[0066] The structure and operation of the emergency controller described above demonstrate its overall simplicity, enabling universal installation within existing vehicle structures without altering the existing vehicle framework. The controller utilizes a minimal number of transitional components, operates in a simple principle, and eliminates the need for specialized transitional decorative molds, resulting in low R&D and installation costs. During operation, the alarm and air circuits achieve synchronized emergency control, effectively ensuring passenger safety.

[0067] It should be noted that, as a preferred embodiment, the handle 200 is vertically arranged in a normal state. When the handle 200 is rotated 45 degrees clockwise, it reaches the first emergency state. When the handle 200 is rotated 90 degrees clockwise, it reaches the second emergency state. The handle 200 can be restored to the normal state by rotating 90 degrees counterclockwise from the second emergency state.

[0068] The structure of the sensor 310 is described in detail below:

[0069] The sensing element includes a cam 312, and the rotator 330 also includes a rotating shaft 335 connected to the rotator body 331. The rotating shaft 335 passes through the distributor body 321 and is connected to the cam 312. The cam 312 is provided with a first protrusion 3121 and a second protrusion 3122. In a normal state, the first protrusion 3121 squeezes the first micro switch 313, and the second protrusion 3122 is separated from the second micro switch 314. When the rotating shaft 335 drives the cam 312 to rotate to the first emergency state, the first protrusion 3121 is separated from the first micro switch 313, and the second protrusion 3122 squeezes the second micro switch 314. When the rotating shaft 335 drives the cam 312 to rotate to the second emergency state, the first protrusion 3121 is separated from the first micro switch 313, and the second protrusion 3122 is separated from the second micro switch 314.

[0070] See Figure 2 、 Figure 3 and Figure 4 . Figure 2 In a normal state, the first protrusion 3121 squeezes the first micro switch 313, thereby disconnecting the first micro switch 313, so that the alarm connector 3151 does not work; the second protrusion 3122 separates from the second micro switch 314, so that the second micro switch 314 is disconnected, and the solenoid valve coil 3161 cannot work. Figure 3 In the first emergency state, the first protrusion 3121 is separated from the first microswitch 313, thereby turning on the first microswitch 313, causing the alarm connector 3151 to work and the alarm to sound an alarm; the second protrusion 3122 squeezes the second microswitch 314, causing the second microswitch 314 to turn on, and the solenoid valve coil 3161 is turned on to open the passenger door. Figure 4 In the second emergency state, the first protrusion 3121 separates from the first microswitch 313, causing the first microswitch 313 to remain on and the alarm to continue sounding. The second protrusion 3122 separates from the second microswitch 314, causing the second microswitch 314 to be off and the solenoid valve coil 3161 to cease operation. It should be noted that the on / off mechanisms of the first and second microswitches 313 and 314 are opposite. When the first protrusion 3121 compresses the first microswitch 313, the first microswitch 313 is off; when the first protrusion 3121 separates from the first microswitch 313, the first microswitch 313 is on. When the second microswitch 314 is pressed by the second protrusion 3122, the second microswitch 314 is on; when the second protrusion 3122 separates from the second microswitch 314, the second microswitch 314 is off.

[0071] By rotating the handle 200 clockwise from the initial state, the first protrusion 3121 moves away from the first microswitch 313, turning on the first microswitch 313 and causing the alarm to sound an alarm signal to alert the passenger. Only by rotating the handle 200 45 degrees clockwise from the initial state to the first emergency state will the second microswitch 314, squeezed by the second protrusion 3122, turn on the solenoid valve coil 3161, opening the passenger door.

[0072] The sensor box 311 is provided with four micro switch mounting holes, two on each side, for mounting the first micro switch 313 and the second micro switch 314 respectively. A square hole is provided at the position of the cam 312 in the middle of the sensor box 311, and combination holes are provided at the four corners of the sensor box 311, the center of the combination hole coincides with the center of the hole position of the base 340. A limiting edging is provided on the side of the sensor box 311 that abuts the gas distributor 320, which can improve the accuracy of the combined installation. A semicircular convex strip is provided on the side of the sensor box 311 that abuts the base 340, which can cooperate with the semicircular groove 3411 provided on the base 340 to achieve sealing and limiting. A sealing ring 410 is provided between the sensor box 311 and the base 340.

[0073] The structure of the gas separator 320 is described in detail below:

[0074] The air path joint includes an air inlet joint 322, an air outlet joint 323, an exhaust joint 324 and a cut-off joint 325. The air inlet joint 322 is arranged opposite to the air outlet joint 323, and the exhaust joint 324 is arranged opposite to the cut-off joint 325. The air outlet joint 323 and the exhaust joint 324 are arranged on the same side of the air distributor body 321. Four air vents 326 are provided on the side where the air distributor body 321 abuts against the rotator body 331. The air vents 326 are connected to the air path joints in a one-to-one correspondence. Under normal conditions, the first air channel 332 connects the air vents of the air inlet joint 322. 326 and the vent hole 326 of the air outlet connector 323, and the second air duct 338 connects the vent hole 326 of the exhaust connector 324 and the vent hole 326 of the shut-off connector 325; in the first emergency state, the first air duct 332 and the second air duct 338 are both separated from the vent hole 326; in the second emergency state, the first air duct 332 connects the vent hole 326 of the air outlet connector 323 and the vent hole 326 of the exhaust connector 324, and the second air duct 338 connects the vent hole 326 of the air inlet connector 322 and the vent hole 326 of the shut-off connector 325.

[0075] See Figures 5 to 9, a rotating shaft hole 328 and a lubrication chamber 327 that match the rotating shaft 335 are provided at the center of the separator body 321. Lubricating oil is added to the lubrication chamber 327 during assembly to lubricate the friction between the rotating shaft 335 and the separator body 321. Threaded holes are provided at the four corners of the separator body 321, and the centers of the threaded holes coincide with the centers of the holes corresponding to the base 340 and the sensor box 311. Four air vents 326 are provided on the side where the separator body 321 abuts the rotator body 331, and each air vent 326 is installed with an air vent sealing ring. The four air vents 326 are respectively connected to the air inlet connector 322, the air outlet connector 323, the exhaust connector 324 and the cut-off connector 325 to form four independent L-shaped air ducts. A muffler is provided at the exhaust connector 324. The other side of the separator body 321 is numbered 1, 2, 3, and 4, with 2 on the upper right, 1 on the upper left, 4 on the lower right, and 3 on the lower left. When in use, if the lower left 3 is connected to the air inlet connector 322, the lower right 4 is connected to the cut-off connector 325, the upper left 1 is connected to the air outlet connector 323, and the upper right 2 is connected to the exhaust connector 324. If the upper left 1 is connected to the air inlet connector 322, the upper right 2 is connected to the cut-off connector 325, the lower left 3 is connected to the air outlet connector 323, and the lower right 4 is connected to the exhaust connector 324.

[0076] Under normal conditions, the first air channel 332 connects the vent 326 of the air inlet connector 322 with the vent 326 of the air outlet connector 323. Gas flows from the air inlet connector 322 through the L-shaped air channel to the vent of the air inlet connector 322, then flows through the first air channel 332 into the vent 326 of the air outlet connector 323, and finally reaches the air outlet connector 323 through the L-shaped air channel for exhaust. The air circuit and the door pump operate normally. The second air channel 338 connects the vent 326 of the air outlet connector 324 with the vent 326 of the shut-off connector 325. The shut-off connector 325 blocks the air circuit. Under the first emergency condition, the first and second air channels 332 and 338 are separated from the vent 326, disconnecting the air circuit and thus cutting off the air circuit to the passenger door. Due to the connection of the solenoid valve coil 3161 under the first emergency condition, the passenger door is opened in an emergency. In the second emergency state, the first air duct 332 connects the vent 326 of the air outlet connector 323 and the vent 326 of the exhaust connector 324. The gas flows from the air outlet connector 323 through the L-shaped air duct to the vent 326 of the air outlet connector 323, and then flows into the vent 326 of the exhaust connector 324 through the first air duct 332, and finally reaches the exhaust connector 324 through the L-shaped air duct for exhaust, thereby discharging the remaining air in the working air pump, making it easier to push open the passenger door and ensure the safety of the occupants; the second air duct 338 connects the vent 326 of the air inlet connector 322 and the vent 326 of the cut-off connector 325. The cut-off connector 325 blocks the air path and causes the air to be cut off, thereby ensuring the working air pressure of the entire vehicle.

[0077] The structure of the rotator 330 is described in detail below:

[0078] The first air hole 333, the second air hole 334, the third air hole 3341 and the fourth air hole 3342 are provided on the side where the rotator body 331 abuts the gas distributor body 321. The first air hole 333, the second air hole 334, the third air hole 3341 and the fourth air hole 3342 are arranged corresponding to the vent hole 326. The first air hole 333 and the second air hole 334 are connected to form the first air channel 332. The third air hole 3341 and the fourth air hole 3342 are connected to form the second air channel 338.

[0079] See Figures 10 to 12 A U-shaped first air channel 332 and a second air channel 338 are respectively provided on either side of the rotation center of the rotator body 331. Steel balls 336 are hammered into the two air channels to plug the machined openings, thus forming the U-shape. The first and second air channels 332 and 338 have the same structure, shape, and aperture. A square boss 337 is provided at the rear end of the rotating shaft 335, which mates with the cam 312. The height of the square boss 337 is equal to the thickness of the cam 312, ensuring that the rotating shaft 335 and cam 312 rotate synchronously.

[0080] Furthermore, the distributor body 321 is provided with a first groove, the rotator body 331 is provided in the first groove, and there is a gap between the rotator body 331 and the side wall of the first groove. A limit block 3211 is provided in the first groove protruding toward the rotator body 331, and the rotator body 331 is circumferentially provided with a first limit foot 3311 and a second limit foot 3312; in a normal state, the limit block 3211 abuts against the first limit foot 3311, and the limit block 3211 limits the rotator body 331 to rotate unidirectionally along the first direction; in a second emergency state, the second limit foot 3312 rotates to abut against the limit block 3211, and the limit block 3211 limits the rotator body 331 to rotate unidirectionally along the second direction.

[0081] The limiting cooperation between the limit block 3211, the first limiting foot 3311, and the second limiting foot 3312 limits the rotation of the rotator 330. Under normal conditions, the limit block 3211 abuts against the right side of the first limiting foot 3311, so that the rotator 330 can only rotate in a single direction, clockwise. When the rotator 330 rotates to the position corresponding to the second emergency state, the limit block 3211 abuts against the left side of the second limiting foot 3312, so that the rotator 330 can no longer rotate clockwise and can only rotate counterclockwise. Thus, the limiting cooperation between the limit block 3211, the first limiting foot 3311, and the second limiting foot 3312 limits the direction and angle of rotation of the rotator 330.

[0082] Furthermore, a plurality of protrusion structures 3313 are circumferentially provided on one side of the rotator body 331 facing away from the gas distributor body 321, the protrusion structure 3313 is provided with a plug-in groove 3314, the handle 200 is provided with a second groove, and the second groove is circumferentially provided with a plurality of plug-in blocks 210, which are plugged into and matched with the plug-in groove 3314.

[0083] See Figure 10 and Figure 17 The handle 200 and the rotator body 331 are stably connected through the plug-in cooperation between the plug-in block 210 and the plug-in slot 3314, so that when the handle 200 is rotated, the rotator 330 can rotate synchronously.

[0084] In the optional method of this embodiment, see Figure 18 The outer cover 100 includes a shell 110 and a flip cover 120. The flip cover 120 is rotatably connected to the shell 110 and a receiving cavity is formed therebetween. The handle 200 is disposed in the receiving cavity. A detachable cover of the shell 110 is disposed on the controller assembly.

[0085] See Figure 14 and Figure 15 A rotator outlet hole 125 is provided in the middle of the accommodating cavity to facilitate the assembly of the rotator 330 and the handle 200. Four mixed bolt holes 124 are provided around the circumference of the rotator outlet hole 125 for connecting to the controller assembly. A flip hole 126 is provided in the accommodating cavity, and the buckle 121 of the flip 120 is arranged at the flip hole 126. The flip 120 is made of transparent PC material and the surface is frosted. A rotating shaft 123 and a spring 122 are provided on the upper edge of the flip 120. The spring 122 is embedded in the limiting groove, and the depth of the limiting groove is not less than the diameter of the spring 122. Decorative holes 127 are provided at the four corners of the front of the shell 110, and screw fixing holes 128 are provided at the bottom of the shell 110 for installing the buckle 121. Mounting holes 129 are provided at the four corners of the bottom of the shell 110 for fixing the emergency controller to the inner surface of the vehicle body after assembly is completed.

[0086] Furthermore, a contact switch hole 112 is provided in the accommodating cavity, and an outer cover contact switch 3152 is provided in the contact switch hole 112. The outer cover contact switch 3152 is connected in parallel with the first micro switch 313. In a normal state, the flip cover 120 presses the outer cover contact switch 3152 to disconnect the outer cover contact switch 3152. After the flip cover 120 is rotated and opened relative to the housing 110, the outer cover contact switch 3152 is turned on and an alarm is issued.

[0087] See Figure 14In a normal state, the flip cover 120 is buckled on the housing 110, and the flip cover 120 presses the outer cover contact switch 3152, which is disconnected and does not trigger the alarm mechanism; in an emergency state, the flip cover 120 is rotated open relative to the housing 110, and the outer cover contact switch 3152 is energized and turned on, triggering the alarm mechanism to send out an alarm signal.

[0088] In the optional method of this embodiment, see Figure 19 The controller assembly also includes a base 340, which is connected to the shell 110 through a positioning structure. The base 340 includes a base body 341 and extensions 342 connected to both sides of the base body 341. The base body 341 is detachably connected to the sensor 310, the gas separator 320 and the rotator 330, and the extension 342 is provided with a fixing hole 3421 for fixing to the vehicle body.

[0089] See Figure 13 The four corners of the base body 341 are provided with screw assembly holes 343, which correspond to the holes in the sensor 310, the gas distributor 320, and the rotator 330. The positioning structure includes a positioning boss 3422 provided on the extension portion 342 and a positioning notch 111 provided on the housing 110. The positioning boss 3422 is plugged into the positioning notch 111.

[0090] The bottom of the housing 110 is provided with a bottom notch 113, which can cooperate with the extension portion 342 to limit the housing 110 and the base 340. The positioning boss 3422 cooperates with the positioning notch 111 to limit the housing 110 and the base 340.

[0091] In the optional method of this embodiment, see Figure 16 and Figure 17 The handle 200 includes a handle seat 220 and a handle rotating part 230. The handle seat 220 and the handle rotating part 230 are penetrated by a handle hole 240. The handle seat 220 is circular, and an arrow is provided on the handle seat 220 to indicate the rotation direction in an emergency state. The handle rotating part 230 is elliptical, and the handle rotating part 230 is connected to the rotator body 331.

[0092] The following describes how to use the emergency controller:

[0093] When an emergency occurs, first press the buckle ear 121 downward, and the flip cover 120 automatically opens. The outer cover contact switch 3152 is turned on, triggering the alarm mechanism to issue an alarm signal. Then, the handle rotating part 230 is rotated clockwise to reach the first emergency state, the alarm is turned on, the passenger door air circuit is cut off, and the solenoid valve coil 3161 is energized, allowing the passenger door to open. The handle rotating part 230 is then rotated clockwise again to reach the second emergency state. The alarm continues to sound, and the emergency full air shutoff state is reached. The remaining air inside is discharged through the exhaust connector 324. At this point, if the passenger door is not open, it can be manually opened. Finally, to restore the state, the handle rotating part 230 is rotated in the opposite direction to the initial state.
