Problems solved by technology

[0002] At present, due to the complexity of the vehicle driving environment, complex vibrations are prone to occur, making the inverted swing tailgate in an unstable state, and there are certain technical defects in the hydraulic system. The gap between the compartments becomes larger
Due to structural and principle defects, the original tailgate locking device cannot lock the tailgate under the above circumstances, resulting in greatly reduced vehicle airtightness and safety, and the safety of passengers is threatened

Embodiment 1

[0026] Such as figure 1 , a bayonet type automatic reset mechanical-hydraulic linkage door lock device in a car, which includes a handle hinge seat 12, a handle 1 is hinged on the handle hinge seat 12, and the other end of the handle 1 passes through a handle adapter plate 2 At the same time, a swivel frame 3 and a connecting rod 4 are hinged, and the other end of the swivel frame 3 is hinged on the hinged seat 11 of the swivel frame, and the swivel frame 3 is matched with a hydraulic valve group 10 for controlling the hydraulic jack of the tailgate; The other end of the connecting rod 4 is hinged to a latch assembly for locking the vehicle door; the latch assembly cooperates with the door pin 6 arranged on the tailgate, and locks the vehicle door. The mechanical-hydraulic linkage door lock device can always maintain stability under complex conditions, and has the advantages of better reliability, simple structure, and convenient installation compared with existing door lock m...

Embodiment 2

[0034] The operation method of the mechanical-hydraulic linkage door lock device with bayonet type automatic reset in any one of the vehicles is characterized in that:

[0035] Closing process:

[0036] When the hydraulic ejector works to pull up the door, the bayonet bolt 5 is pressed down by the door pin 6, and when the door pin 6 reaches the predetermined position, the bayonet pressure spring 9 returns to its original state and lifts the bayonet bolt 5 to block the door pin 6, so as to realize the locking of the car door;

[0037] Door opening process:

[0038] When the door needs to be opened, press down the handle 1, and the handle 1 will synchronously drive the rotary frame 3 and the connecting rod 4 through the handle adapter plate 2, and the contact point 13 on the rotary frame 3 will be in contact with the hydraulic valve group 10, thereby triggering the hydraulic valve group 10 , the hydraulic valve group 10 will control the hydraulic ejector rod to work, and at th...

Abstract

The invention relates to an in-car clamping pin type automatic reset mechanical hydraulic linkage door lock device and an operation method. The device comprises a handle hinge base, a handle is hingedto the handle hinge base, the other end of the handle is hinged with a rotation frame and a connecting rod at the same time through a handle adapter plate, the other end of the rotation frame is hinged to a rotation frame hinge base, the rotation frame is matched with a hydraulic valve set used for controlling a tail door hydraulic ejector rod, the other end of the connecting rod is hinged to a plug pin assembly used for locking a car door, and the plug pin assembly is matched with a car door pin shaft on a tail door and used for locking the car door. The car tail door locking is achieved, and the phenomenon that after long-time use, the tail door cannot be locked, and automatic opening danger is caused is avoided.

Description

technical field [0001] The invention relates to a vehicle door lock mechanism, in particular to a bayonet type automatic reset machine-hydraulic linkage door lock device in a vehicle. Background technique [0002] At present, due to the complexity of the vehicle driving environment, complex vibrations are prone to occur, making the inverted swing tailgate in an unstable state, and there are certain technical defects in the hydraulic system. The gap between the compartments becomes larger. Due to structural and principle defects, the original tailgate locking device cannot lock the tailgate under the above circumstances, resulting in greatly reduced vehicle airtightness and safety, and the safety of passengers is threatened. Contents of the invention [0003] In order to solve the technical problem, the present invention provides a bayonet type automatic reset mechanical-hydraulic linkage door lock device, which can realize the locking of the tailgate of the vehicle and pr...
