DETAILED DESCRIPTION

[0034] The following is a combination of the embodiments of the present invention Figure 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0035] Example 1

[0036] A vehicle door emergency opening system with dual use modes includes a shell 1, a sliding block 2 is slidably installed inside the shell 1, a rack 5 is fixedly connected to one side of the sliding block 2, two limit bars 3 are fixedly connected to both sides of the sliding block 2, a limit slot 4 is provided on both sides of the shell 1, two limit bars 3 on one side of the sliding block 2 are slidably installed inside the limit slot 4, a rotating shaft 6, a gear 7 and a rotating shaft 2 8 are fixedly connected to one side of the inner cavity of the shell 1 in sequence, the surface of the rotating shaft 6 is sleeved with a gear 7, the surface of the rotating shaft 2 8 is sleeved with a gear 2 9, and the The surface of the rotating shaft 3 10 is sleeved with a gear 3 11, and the gear 1 7, gear 2 9 and gear 3 11 are meshed with each other. A mounting hook 21 is slidably installed on one side of the housing 1, and one side of the mounting hook 21 is fixedly connected to a rack 22 located above the gear 3 11, and the rack 2 22 is meshed with the gear 3 11. A bottom cover 32 is plugged and installed at the bottom of the housing 1, and a mounting column 13 adapted to the sliding block 2 is fixedly connected to the top of the bottom cover 32. A spring 12 is sleeved on the surface of the mounting column 13, and the end of the spring 12 away from the bottom cover 32 is fixedly connected to the inner wall of the sliding block 2.

[0037] The specific usage process is as follows: when the user opens the car door, he directly presses the button 20, which drives the movable block 17 to slide in the housing 1. At the same time, the movable block 17 also slides on the surface of the sliding block 2, and the limiting strip 18 set on the movable block 17 also slides in the corresponding limiting notch 19. Therefore, when the movable block 17 is pressed by the user, the limiting strip 18 also slides inside the limiting notch 19 with the movable block 17, thereby limiting the movement of the movable block 17, preventing the movable block 17 from moving at will, and improving the stability of the movable block 17. 7 Stability during use, providing convenience for users. As the movable block 17 moves downward, the button 20 will contact the switch 16 and press the switch 16, so that the switch 16 will be turned on, and then the circuit on the circuit board 15 will be connected. The door opening command can be transmitted to the circuit line 30 through the circuit board 15, and then transmitted to the body module through the circuit line 30, that is, the command is transmitted to the "vehicle terminal", and then the "vehicle terminal" controls the door opening. In this way, the user can quickly open the door in normal use, providing convenience for the user;

[0038] When the above-mentioned door opening system fails and the door cannot be opened, the user can also manually open the door by operating the emergency door opening system to avoid being trapped in the car. The specific operation is as follows: when the user uses the above-mentioned door opening mode and there is no response, and the door does not open, the user continues to press down. At this time, as the button 20 is continued to be pressed, the movable block 17 will continue to move downward, and then the bottom of the movable block 17 will contact the flange, and then the flange will be pressed downward, so that the sliding block 2 will also move downward, wherein the flange will lift the movable block 17, thereby limiting the movement of the movable block 17, preventing the movable block 17 from exceeding its set stroke during movement, and preventing the limit bar 2 18 from being stuck in the shell 1, causing the movable block 17 to move downward. The movement of block 17 is limited, which ensures the smooth movement of movable block 17 and provides convenience for users. Afterwards, sliding block 2 will move downward and drive rack 15 to move downward. As rack 15 moves downward, rack 15 will also drive gear 17 to rotate, and then gear 17 drives gear 29 to rotate, and gear 29 will drive gear 3 11 to rotate, because rack 15, gear 17 and gear 29 are meshed with each other in sequence, and gear 17 is meshed with gear 3 11. This is the existing technology, and then the rotation of gear 3 11 will also drive rack 22 to slide in the inner cavity of shell 1, and rack 22 will drive the mounting hook 21 to slide in the inner cavity of shell 1, and then the end of the mounting hook 21 will pull the corresponding component to drive the lock pin to move, thereby realizing the door The unlocking of the door is a prior art and will not be described in detail in this article. In this way, the emergency opening of the door can be completed, ensuring that the door can be opened in time in an emergency, avoiding the user from being trapped in the car, improving the user's personal safety, and providing convenience for the user to use the vehicle. At the same time, when the mounting hook 21 is working, the convex strip will also slide in the limiting slide groove 28, so that the sliding of the mounting hook 21 can be limited, improving the stability of the mounting hook 21 when sliding, and providing convenience for the user. The sliding block 2 will also compress the spring 12 downward when it moves down, and then after the user has finished using it, the sliding block 2 can also be lifted up and reset under the action of the spring 12 to prepare for the next operation. Among them, the positioning block 23, the positioning groove 24, and the spring The arrangement of the slot 25, the positioning pin 26 and the second spring 27, the spring slot 25, the positioning pin 26 and the second spring 27 are installed on the sliding block 2, so when the sliding block 2 is working, under the action of the second spring 27, the end of the positioning pin 26 is stuck in the positioning slot 24, thereby realizing the positioning of the sliding block 2, and also realizing the positioning of the rack 1 5, ensuring the accuracy and sensitivity of the user's operation of the emergency switch device, providing convenience for the user. It should be noted that this structure can also prevent accidental touch when the user does not use the emergency door opening system. That is to say, when the user uses the circuit control to open the door, after the button 20 presses the switch 16 to work, the sliding block 2 will be positioned in the current position under the cooperation of the positioning slot 24, the positioning pin 26 and the second spring 27.The sliding block 2 will only continue to move when the user continues to press harder, thus ensuring the accuracy and sensitivity of the entire door opening system.
