The above-mentioned button-type passenger car door emergency valve solves the problem that when the existing emergency valve is used, the valve cover and the valve body are separated slowly, causing great safety hazards, through the cooperation of the adjusting rod and the second elastic card plate."

[0004] However, the button-type passenger car door emergency valve in the above-mentioned public document mainly considers solving the problem that when the existing emergency valve is used, the valve cover and the valve body separate slowly, causing great safety hazards, and it is inconvenient to push the emergency handle to rotate and assist the emergency valve body to open or close. Because the existing emergency valve body requires manual rotation of the emergency handle to operate the emergency valve body, and the manual rotation of the emergency handle opens slowly, causing great safety hazards.

[0005] In view of this, it is necessary to develop an auxiliary pushing mechanism, which can push the emergency handle to rotate and assist the emergency valve body to open or close. Utility Model Content

The auxiliary pushing mechanism includes a mounting plate 5, which is arranged on the inner wall of the emergency valve body 1, and a control button 6 is installed on the outer wall of the mounting plate 5, and a motor 7 is installed on the outer wall of the mounting plate 5. A rotating shaft 8 is installed on the output end of the motor 7, and a rotating groove 9 is provided on the top of the emergency handle 3, and the rotating shaft 8 is located inside the rotating groove 9, and the rotating shaft 8 is movably connected to the rotating groove 9, and a fixing plate 10 is installed on the outer wall of the rotating shaft 8, and a mounting groove 11 is provided on the outer wall of the fixing plate 10, and an electric telescopic rod 12 is installed on the inner wall of the mounting groove 11, and a fixing block 13 is installed on the output end of the electric telescopic rod 12, and the outer wall of the emergency handle 3 A fixing groove 14 is provided. The existing emergency valve body 1 requires manual rotation of the emergency handle 3 to operate the emergency valve body 1. Manual rotation of the emergency handle 3 is slow to open, causing great safety hazards. Therefore, the emergency handle 3 needs to be rotated quickly to open the emergency valve body 1. Pressing the control button 6 makes the electric telescopic rod 12 work and drive the fixing block 13 to move to the fixing groove 14, so that the fixing plate 10 and the emergency handle 3 are in a linkage state. Then the motor 7 works to drive the rotating shaft 8 to rotate in the rotating groove 9, so that the fixing plate 10 rotates, and the fixed plate 10 rotates to drive the emergency handle 3 to rotate, so that the emergency handle 3 is twisted, and there is no need for manual rotation, thereby increasing the rotation speed and avoiding affecting the escape time of the passengers due to the slow rotation speed.

[0028] See also Figure 1 and Figure 4The outer wall of the emergency valve body 1 is provided with a pop-up device, which is used to quickly pop up the protective cover 4, so that the emergency valve can be used quickly. The pop-up device includes a locking rod 15, which is arranged on the outer wall of the protective cover 4, and the outer wall of the locking rod 15 is installed with a magnet body 16. The outer wall of the emergency valve body 1 is provided with a locking groove 17, and the inner wall of the locking groove 17 is installed with an electromagnet 18. The outer wall of the emergency valve body 1 is installed with a power-on button 19, and the outer wall of the emergency valve body 1 is provided with a pop-up groove 20, and the inner wall of the pop-up groove 20 is installed with a sleeve 21, and the inner wall of the sleeve 21 is installed with a rod body 22, and the outer wall of the rod body 22 is installed with a plate 23, and the inner wall of the pop-up groove 20 is installed with a spring 24, and one end of the spring 24 extends to the outer wall of the plate 23, and the outer wall of the plate 23 is installed with a pop-up block 25. When the existing emergency valve body 1 is used, the protective cover 4 is manually opened slowly, which causes a great deal of damage. The safety hazard of the emergency valve body 1 is affected, which affects the escape time of the passengers. Therefore, it is necessary to quickly pop up the protective cover 4 to open it for the convenience of using the emergency valve body 1. The protective cover 4 is covered, the locking rod 15 moves into the locking groove 17, and the outer wall of the protective cover 4 is squeezed by the pop-up block 25, so that the rod body 22 moves in the sleeve 21, and the spring 24 is in a compressed state, so that the magnet body 16 and the electromagnet 18 fit together, and then the power-on button 19 is pressed. The electromagnet 18 is energized and then the magnet body 16 is adsorbed to fix the position of the protective cover 4, and the spring 24 is under pressure. When the emergency valve body 1 needs to be used, the power-on button 19 is pressed to cut off the power to the electromagnet 18, and then the spring 24 is reset to push the plate 23 to move, which pushes the pop-up block 25 to move, and the pop-up block 25 pops up the protective cover 4, so that the protective cover 4 can be quickly opened, avoiding the influence of the escape efficiency due to the slow manual opening speed.
