Description

Technical Field

[0001] The invention relates to the field of vehicle structures, in particular to a double-acting door lock structure and a vehicle. Background Art

[0002] Door locks are an important part of a vehicle. They mainly include a lock body, which is a component fixed inside the door. It contains a series of mechanical linkage mechanisms, mainly the lock tongue on the door and the lock pin on the body working together. The lock pin is fixed to the body, and the lock tongue is linked to the handle on the door. When the door is closed, the lock tongue jams the lock pin. When the door is opened, pull the door handle, the lock tongue rotates and disengages from the lock pin.

[0003] Since the door lock mechanical structure is relatively complex and has many parts, it is more prone to failure. Especially in the event of a vehicle accident, the door lock may be damaged by the impact, which may cause the door to be unable to open normally, greatly hindering the escape of the occupants.

[0004] In case of emergency, the current plan is to lower the doors and windows urgently or break the windows to escape. The escape route is small, which is not conducive to the safe evacuation of the passengers. As for the door lock failure in daily use, the door cannot be unlocked and opened. The passengers usually cannot get out of the vehicle without damaging the vehicle. Summary of the invention

[0005] The present invention provides a double-action door lock structure to solve the problem that the door cannot be opened normally after the door opening mechanism of the current door lock is damaged, making escape difficult.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is a double-action door lock structure, including a lock pin and a lock tongue, a notch for hooking the lock pin on the lock tongue, the lock tongue is connected to the door handle assembly through a first transmission mechanism, the lock pin is configured to be movable along its length, and the lock pin is connected to the emergency handle assembly through a second transmission mechanism. This solution sets the door lock to have two opening modes. Under normal conditions, the door is opened normally by driving the lock tongue through the door handle. When the first transmission mechanism or door handle that controls the lock tongue on the door is damaged, the lock pin can be pulled out through the emergency handle to release the lock and quickly open the door, thereby improving emergency response capabilities and vehicle safety.

[0007] Preferably, it also includes a locking pin mounting seat, the locking pin mounting seat includes a mounting tube, the locking pin is slidably mounted in the mounting tube, the second transmission mechanism includes a second drawing wire, the first end of the second drawing wire is connected to the locking pin, and the second end of the second drawing wire is connected to the emergency handle assembly.

[0008] Preferably, a side wall of the mounting tube is provided with a slot along the length direction, an outer peripheral surface of the locking pin is provided with a connecting protrusion, the connecting protrusion is located in the slot and can slide in the slot, and the second wire drawing is connected to the connecting protrusion.

[0009] Preferably, a blocking piece is provided at the rear end of the mounting tube, and a reset spring is also provided in the mounting tube, the reset spring being located between the rear end of the locking pin and the blocking piece. The locking pin can be driven to reset by the reset spring.

[0010] Preferably, the emergency handle assembly includes an emergency handle seat and an emergency handle, the emergency handle is hingedly mounted on the emergency handle seat, the two sides of the hinge point of the emergency handle are respectively provided with an operating part and a pull rod part, the pull rod part extends in a direction away from the hinge point, and the second end of the second wire is connected to the pull rod part. The pull rod form is adopted, which is convenient for operation.

[0011] Preferably, a second guide seat is further provided on the emergency handle seat, a through hole is provided on the second guide seat, and the second wire drawing passes through the through hole of the second guide seat.

[0012] Preferably, a reset torsion spring is further provided at the hinge shaft between the emergency handle and the emergency handle seat to assist the emergency handle in resetting.

[0013] Preferably, the lock tongue is installed in a lock tongue mounting seat, and the first transmission mechanism includes a first drawwire connected to the door handle assembly.

[0014] Preferably, a first guide seat is provided on the path of the first wire drawing, and the first wire drawing passes through the first guide seat.

[0015] On the other hand, the present invention further provides a vehicle, which adopts the above-mentioned double-action door lock structure.

[0016] It can be seen from the above technical scheme that the advantages of the present invention are: this scheme designs a door lock structure with two opening methods. When the door is damaged and cannot be opened normally, the emergency handle can be pulled to pull out the lock pin, release the lock with the lock tongue, and then open the door. In an emergency, there is no need to break the vehicle body, thereby improving the emergency response capability and vehicle safety; the lock pin and the lock tongue are both driven by wire drawing and have a certain deformation ability, so they can function even if the vehicle body structure is deformed.
