[0047] Example 1

[0048] In many current traffic accidents, there are situations where the driver and passengers are trapped in the vehicle and unable to escape or be rescued. Especially when the driver and passengers are in a coma during the accident and the car door lock is locked, rescue personnel cannot carry out the rescue. If the vehicle catches fire at this time, it will lead to heavy consequences. Based on this, the technical problem of this application emerges, and a device for automatically demolishing car door 2 is provided. The following will elaborate on a device for automatically demolishing car door 2 provided by this application in detail. Figures 1 - 6 Elaborate in detail on a device for automatically demolishing car door 2 provided by this application.

[0049] The device for automatically demolishing car door 2 is used to remove the car door hinge 3 and the car door lock of car door 2 from the vehicle body 1, that is, when a traffic accident occurs, it can completely separate car door 2 from vehicle body 1. In this way, it is convenient for subsequent rescue or escape. Specifically, in combination with Figure 1As shown, the automatic door breaking device of the vehicle door 2 includes a hinge position removal component, which has a limiting part 27, a driving part, and a reset part 5. Among them, a limiting hole 4 is provided at the position of the vehicle door hinge 3 during the production (assembly) of the vehicle. The driving part is connected to the limiting part 27, and the driving part drives the limiting part 27 to move into the limiting hole 4. At this time, when the limiting part 27 is inserted into the limiting hole 4, the limiting part 27 limits and fixes the vehicle door hinge 3, and the vehicle door hinge 3 cannot be displaced under the action of the limiting part 27. In addition, when the limiting part 27 is inserted into the limiting hole 4, the reset part 5 is always arranged in a compressed state at the end of the vehicle door 2 and the vehicle door hinge 3. Further, the driving part can also drive the limiting part 27 to disengage (fall off) from the limiting hole 4. Once the limiting part 27 disengages from the limiting hole 4, that is, when the limiting part 27 no longer limits and fixes the vehicle door hinge 3, the reset part 5 will reset and push the vehicle door hinge 3 to move, so that the vehicle door hinge 3 is separated from the vehicle door 2, and further the vehicle door 2 is separated from the vehicle body 1. The above realizes the separation of the vehicle door hinge 3 and the vehicle door 2 through the limiting part 27, the driving part, and the reset part 5, and the unlocking of the vehicle door 2 lock position is realized in a linkage manner. Specifically, the automatic door breaking device of the vehicle door 2 further includes a linkage component. One end of the linkage component is connected to the limiting part 27 and the other end is connected to the door lock position removal component 26. Once a traffic accident occurs, the driving part will drive the limiting part 27 to fall off from the limiting hole 4. When the limiting part 27 falls off from the limiting hole 4, the limiting part 27 can start the door lock position removal component 26 through the linkage component, so that the vehicle door 2 lock is opened, that is, the unlocking of the vehicle door 2 lock position is completed at this time. It can be seen from the above process that once the unlocking is achieved at the vehicle door hinge 3, through the linkage action of the linkage component, the unlocking at the vehicle door 2 lock position can be achieved, so that the vehicle door 2 is completely unlocked from the vehicle body 1 (combined with Figure 2 shown), which is convenient for subsequent escape and rescue.

[0050] Optionally, the reset part 5 is a reset spring 25

[0051] In this embodiment, the limiting part 27 includes a locking part and a guiding part 8. Among them, for the locking part, combined with Figure 5 and Figure 6As shown, the locking member includes a support frame 6 and an airbag 7, and the support frame 6 is disposed inside the airbag 7. The support frame 6 is preferably a cuboid support frame. The airbag 7 has a certain elasticity and is preferably a rubber airbag 7. When the airbag 7 is not inflated, the airbag 7 can basically adhere to the support frame 6. Note that in this state, the size of the locking member is smaller than the size of the limiting hole 4, that is, the length, width, and height of the locking member are all smaller than the length, width, and height of the limiting hole 4. That is, at this time, the locking member can move out of the limiting hole 4. In addition, when the locking member is located in the limiting hole 4 and the airbag 7 is inflated, it can make the airbag 7 adhere only to the side wall of the limiting hole 4, so as to realize that the locking member is locked in the limiting hole 4.

[0052] Combined with Figure 3 and Figure 4 As shown, for the guiding member 8, it is disposed on the side of the airbag 7 facing away from the limiting hole 4 when the locking member is not in the limiting hole 4, and the guiding member 8 is provided with an air flow channel 9 communicating with the airbag 7, that is, the airbag 7 can be inflated through the air flow channel 9. Optionally, the guiding member 8 is a guiding rod, that is, a rod-shaped structure. The air flow channel 9 extends along the length direction of the guiding rod and penetrates both ends in the length direction of the guiding rod, that is, when inflated from one end of the air flow channel 9, the airbag 7 can be inflated through the other end of the air flow channel 9.

[0053] Furthermore, combined with Figure 5 and Figure 6 As shown, the locking member further includes a supporting metal sheet 10; the airbag 7 is provided with a supporting metal sheet 10 corresponding to the side wall of the support frame 6. The supporting metal sheet 10 is in a plate-like structure and has a certain supporting effect. When the airbag 7 is inflated and expanded, the supporting metal sheet 10 will adhere to the side wall of the limiting hole 4 in a fixed plate-like plane structure, ensuring that all positions of the locking member are completely and without dead angles adhered to the side wall of the limiting hole 4, so as to realize that the locking member is locked in the limiting hole 4.

[0054] Furthermore, combined with Figure 5 and Figure 6 As shown, the locking member further includes an inserting and guiding end 11; when the locking member is not in the limiting hole 4, the inserting and guiding end 11 is disposed on the airbag 7 and is located at one end of the airbag 7 facing the limiting hole 4. Further, the inserting and guiding end 11 has a tapered structure extending outward from the airbag 7, that is, the size of the end of the inserting and guiding joint facing away from the airbag 7 is the smallest. Combined with Figure 5 and Figure 6 As shown, the cross-section of the inserting and guiding joint is triangular and has an inserting and guiding tip. With such a setting, when the locking member moves towards the limiting hole 4, the inserting and guiding tip enters the limiting hole 4 first. Since the size of the inserting and guiding tip is much smaller than the size of the limiting hole 4, at this time, the inserting and guiding tip will play a certain guiding role for the airbag 7, enabling the locking member to smoothly enter the limiting hole 4 without jamming problems.

[0055] In this embodiment, in combination with Figure 3 As shown, the driving part includes a first inflatable chamber 12 and a second inflatable chamber 13. Among them, the first inflatable chamber 12 is divided into a first inflation area, a recovery area 14 and a second inflation area; the second inflatable chamber 13 is arranged in the second inflation area, and the second inflatable chamber 13 is communicated with the air flow channel 9 through an air guide channel 15. Optionally, the air guide channel 15 is an air guide hose. The recovery area 14 is communicated with the first inflation area, and the recovery area 14 can accommodate the locking part.

[0056] Specifically, a conduction channel 16 is opened in the recovery area 14. The shape of the conduction channel 16 is the same as that of the connection part 8, and the size is larger than that of the connection part 8, that is, the connection part 8 can enter the recovery area 14 along the conduction channel 16.

[0057] During the actual use process, when inflating the recovery area 14 through the first inflation area, the air pressure in the recovery area 14 will be increased. As the air pressure in the recovery area 14 increases, the air pressure in the recovery area 14 will push against the connection part 8 and discharge the connection part 8 from the conduction channel 16, and finally move to the limit hole 4. When the limiting part 27 moves to the limit hole 4, the second inflatable chamber 13 is inflated, and the airbag 7 is inflated through the air guide channel 15 and the air flow channel 9, so that the supporting metal sheet 10 is attached to the side wall of the limit hole 4. The above process will completely realize the locking of the locking part in the limit hole 4. It should be noted that: the above process should be completed during the assembly of the whole vehicle. That is to say, when buying a new car, the locking part is already located in the limit hole 4.

[0058] When an accident occurs, the second inflatable chamber 13 deflates, and the airbag 7 deflates through the air guide channel 15 and the air flow channel 9, so that the supporting metal sheet 10 falls off the limit hole 4; when the supporting metal sheet 10 falls off the limit hole 4, the first inflatable chamber 12 quickly deflates, so that the locking part quickly retracts into the recovery area 14 through the conduction channel 16; in addition, when the locking part retracts into the recovery area 14, the reset part 5 resets and drives the door hinge 3 to fall off the door 2, thereby realizing the separation of the door hinge 3 and the door 2.

[0059] Further, in combination with Figure 3 As shown, a first inflation valve 17 and a first ignition component 18 are arranged on the first inflatable chamber 12; a second inflation valve 19 and a second ignition component 20 are arranged on the second inflatable chamber 13. When the first inflation valve 17 and the first ignition component 18 are opened, the first inflatable chamber 12 can be inflated. When the second inflation valve 19 and the second ignition component 20 are opened, the second inflatable chamber 13 can be inflated.

[0060] The structures of the first ignition component 18 and the second ignition component 20 are the same, and are also an existing structure, such as the airbag 7 on a vehicle, which includes chemicals, such as a gas generator. When a collision occurs, the gas generator ignites the gas generator to inflate the airbag 7.

[0061] In this embodiment, combined with Figure 3 and Figure 4 As shown, the linkage assembly includes a linkage contact rod 21, a trigger wire 22 and a pulley 23. One end of the linkage contact rod 21 is set on the guide member 8, and the other end extends toward the door lock position removal assembly 26 and passes through the first air chamber 12. One end of the trigger wire 22 is connected to the end of the linkage contact rod 21 away from the guide member 8, and the other end is connected to the door lock position removal assembly 26 through the pulley 23. It should be noted that the trigger wire 22 is a metal wire and can have a certain deformation. Once a collision occurs in the car, the metal wire can be deformed to a certain extent along with the deformation of the car.

[0062] In actual use, combined with Figure 4 As shown, when the limiting portion 27 falls off from the limiting hole 4, the linkage touch rod 21 moves toward the door lock position removal assembly 26, and the door lock position removal assembly 26 can be triggered and started through the pulley 23 and the trigger line 22. Specifically, when the linkage touch rod 21 moves toward the door lock position removal assembly 26, the trigger line 22 is pulled, so that the trigger line 22 pulls the door lock position removal assembly 26.

[0063] Furthermore, the door lock position removal component 26 includes a door handle 24, where the handle refers to the axis of the handle in the vehicle door 2, that is, the trigger wire 22 is connected to the axis of the handle. In other words, when the linkage contact rod 21 moves toward the door lock position removal component 26, it will pull the trigger wire 22, so that the trigger wire 22 pulls the axis of the handle, so that the handle unlocks the vehicle door lock 28, that is, opens the vehicle door 2.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
