To achieve the goals above, the present invention adopts the following technical scheme:

A kind of automobile door handle device, including handle lever mechanism, automatic resetting mechanism, gate lock actuator, mechanical lock Mechanism and electronic lock mechanisms；

The handle lever mechanism is made of handle, handle brackets and support shaft, and handle brackets are fixed on car door, support Axis is laterally hubbed in handle brackets, and handle is arranged among handle brackets and is hubbed in support shaft on the downside of handle middle-end, So that handle can be around support shaft in handle brackets central rotational；

The automatic resetting mechanism is made of return bracket, push rod, return spring and screw shell；The return bracket is solid It is scheduled on car door, the through-hole for passing through and moving up and down for push rod is opened up among return bracket, the front end of handle is located at return bracket Top center, push rod upper end pass through and are pivotally connected on the downside of the through-hole and handle front end；The screw shell upper end is bolted in return branch The through hole periphery of frame, return spring is arranged in screw shell, and return spring lower end is connected to screw shell bottom；It is described to push away Bar lower end forms rack gear, and push rod runs through the screw shell and return spring, and push rod upper end outer peripheral surface forms stop collar, return bullet The upper end of spring is connected on the stop collar；

The gate lock actuator includes executing shaft, being fixed on the first partial gear and positioning tooth executed in shaft Wheel, first partial gear be fixed on execute shaft front end, execute shaft rear end formed impeller, the impeller with The driving part of door lock connects, and the first partial gear is engaged with the rack gear of push rod；

The mechanical lock mechanism includes lock core, the first bevel gear for being fixed on lock core end and intermediate mesh piece, the lock First bevel gear on core is engaged by the intermediate mesh piece with the positioning gear for executing shaft front end；

The electronic lock mechanisms include pulse motor and are fixed on pulse motor output shaft and drive gear, the sliding tooth It takes turns and is engaged with the positioning gear for executing shaft front end.

The handle brackets are made of two pieces of right angled triangle framves, the right-angle side and handle of two pieces of right angled triangle framves The parallel and side is fixed by screws on car door, and two pieces of right angled triangle frame front ends open up axis hole, and support shaft is hubbed on two On the axis hole of block right angled triangle frame front end；

The door handle further includes a limit connecting rod, and two pieces of right angled triangle frame rear ends bottom opens up axis hole, One connection shaft is laterally hubbed on the axis hole of two pieces of right angled triangle frame rear ends bottom；The handle end is also pivoted a connection Shaft, the connection shaft for limiting connecting rod one end and handle end are pivotally connected, the connection of the other end and two pieces of right angled triangle frame rear ends Shaft pivot joint.

Handle is formed on the downside of the handle end, is pivoted on handle and connects shaft, limits the other end and the connection of connecting rod Shaft pivot joint.

The recessed formation press section in handle front end, the bottom of press section is covered with anti-skidding convex grain.

The front and rear end for executing shaft is respectively provided with a hold-down support, and hold-down support upper end is fixed by screws in vehicle Men Shang, hold-down support lower end form the interconnecting piece for having axis hole, and the front and rear end for executing shaft is hubbed on hold-down support respectively Interconnecting piece on.

The intermediate mesh piece by intermediate rotary shaft, be fixed on the second partial gear of intermediate rotary shaft middle-end and be fixed on The second bevel gear of intermediate rotary shaft front end forms, and the second bevel gear is engaged with the first bevel gear on lock core, and second is endless All gear is engaged with the first partial gear executed in shaft.
