An automobile emergency unlocking system comprises a lock assembly 10, wherein the lock assembly 10 is connected with an outward opening pull rod 11 and an inward opening pull rod 12, the inward opening pull rod 12 is connected with an inward opening handle, and an unlocking actuator 20 is started to release pressure gas to drive and release the safety of an automobile door lock when a collision detection module detects that an automobile severe collision accident occurs.
According to the scheme, the emergency unlocking system provided by the invention is a system for timely unlocking the safety of the vehicle door lock when a vehicle is in a severe collision, the lock assembly 10 formed by connecting the external opening pull rod 11, the internal opening pull wire 12 and the internal opening pull wire 12 with the internal opening handle continuously adopts the prior art, only the unlocking actuator 20 is additionally arranged, when the collision detection module detects the severe collision accident of the vehicle, the unlocking actuator 20 is started and releases pressure gas, and the pressure gas can be timely driven by the special response rapidity of the gas and can unlock the safety of the vehicle door lock.
One of the basic schemes for releasing the safety of the vehicle door lock is that an unlocking actuator 20 is connected with an inner opening pull wire 12, and the locking actuator 20 releases pressure gas to drive the inner opening pull wire 12 to displace and release the safety of the vehicle door lock; secondly, the lock actuator 20 releases the pressure gas to drive the door lock to move and unlock.
The first of the above solutions is that the inside opening cable 12 is on the driving side, because normally, the inside opening cable 12 on the driving side and the door lock safety on the driving side are in an interlocking structure, that is, when the inside opening cable 12 on the driving side is pulled, all the door lock safety in the vehicle is released at the same time; the second scheme is that all the door lock safeties are directly driven, so that even if one door lock safety is unable to be opened, other door lock safeties always have the chance to be unlocked, and the situation that the door lock safety is unable to be unlocked by the inner opening wire 12 due to damage of the inner opening wire 12 on the driving side or due to some special reason can be avoided. Of course, the mounting may be properly selected and selected in view of the safety of the door lock of the front passenger seat or the rear left and right doors, while considering the mounting on the inner opening wire 12 on the driver's side.
Preferably, the unlocking actuator 20 is an explosion-type actuator, and when the collision detection module detects the occurrence of a severe collision accident of the automobile, an explosion signal is sent to ignite the explosion-type unlocking actuator 20 to release explosion gas and drive the inner pull wire 12 to displace, thereby releasing the safety of the automobile door lock.
The unlocking actuator 20 which adopts an explosion type scheme to release pressure gas occupies a small space under the normal condition, the pressure of the released gas can be enough, and the unlocking actuator is suitable for the installation of a vehicle door part and belongs to an optimal scheme; alternatively, the supply of pressure gas may be arranged as a small pressure gas tank connected to the movement actuator of the actuator via a switching valve.
Preferably, the collision detection module sends out an airbag ignition signal and an ignition signal of the explosion type unlocking actuator 20 simultaneously when detecting the occurrence of the severe collision accident of the automobile. The scheme can simplify the setting of the detonation signal, namely, the existing airbag detonation signal is utilized, the reliability of the signal and the burning and explosion necessity of the unlocking actuator 20 can be ensured, once the collision detection module detects the occurrence of the severe collision accident of the automobile, the severe degree of the collision detection module is enough to output the signal to ignite the safety airbag, and the signal is output to the unlocking actuator 20 all the way.
The unlocking actuator 20 is connected to the inner opening wire 12 and is spaced apart from the lock assembly 10 and the inner door handle. Therefore, the possibility that the inner opening pull wire 12 is pulled can be ensured, and the situation that the inner opening pull wire 12 cannot be displaced is avoided; preferably, the unlocking actuator 20 is connected to the middle position of the inner opening wire 12. The selection of the setting position ensures that the inner opening wire 12 can be pulled to be displaced when the unlocking actuator 20 is exploded.
The unlocking actuator 20 comprises an ignition assembly 21, a gas producing medicine 22 is filled in a rodless cavity of a cylinder body 23, a piston top rod 24 is connected with the inner pull wire 12, and explosive gas drives the piston top rod 24 and the inner pull wire 12 to displace towards the direction of releasing the door lock safety. In fact, the unlocking actuator 20 is connected to the inner pull wire 12, and when the piston rod 24 drives the inner pull wire 12 to displace, the action of safe unlocking of the door lock is synchronously realized.
The cylinder 23 includes inner and outer tube walls 231, 232, and one end of the two is connected to form a structure with a sealing end cover 233 at one end, a tubular piston rod 24 is arranged in a clamping cavity between the inner and outer tube walls 231, 232, the outer end of the piston rod 24 is connected with a transition connection disc 25, a hole is arranged in the middle of the transition connection disc 25 for the inner pull wire 12 to pass through and the two are fixedly connected. By adopting the scheme, the tubular piston mandril 24 is arranged in the clamping cavity between the inner and outer pipe walls 231 and 232, so that the inner pipe cavity of the inner pipe wall 231 is ensured to be a through passage, the inner pull wire 12 connected with the transition connecting disc 25 can pass through, and the pulling force applied to the inner pull wire 12 is consistent with the wire length direction.
More specifically, when the transition connecting disc 25 is attached to the end of the inner pipe wall 231 or the outer pipe wall 232, a space for containing the gas generant 22 is formed between the inner end of the piston mandril 24 and the plugging end cover 233. That is, when the vehicle door is in a normally closed state, the transition connection disc 25 is attached to the pipe end of the inner pipe wall 231 or the outer pipe wall 232, and the inner end of the piston rod 24 cannot extrude the gas generant 22, and it should be noted here that the small gap is only required to be formed between the piston portion of the inner end of the piston rod 24 and the clamping cavity, i.e., the cylinder cavity, between the inner pipe wall 231 and the outer pipe wall 232, and a sealing fit is not required, because when the vehicle door is normally opened, the inner pull wire 12 and the transition connection disc 25 synchronously displace, thereby avoiding that a local area is in a negative pressure environment, the displacement of the transition connection disc 25 and the piston rod 24 is difficult, and further the inner pull wire 12 is difficult to pull.
The invention also provides a scheme for realizing the matching of the transition connecting disc 25 and the inner opening stay wire 12, namely, a hole is formed in the middle of the transition connecting disc 25 for the inner opening stay wire 12 to pass through, a clamping piece 121 is connected to the inner opening stay wire 12, and the clamping piece 121 is arranged close to the outer side face of the transition connecting disc 25. This scheme does not influence the action of opening the door under the normal condition of interior division line 12, and in case when the collision accident takes place, gas production medicine 22 explodes, ensures during transition connection pad 25 displacement again can support with card firmware 121 and drive interior division line 12 displacement, realizes the unblock action.
