Description

TECHNICAL FIELD

[0001] The present application relates to the field of handles, in particular to a flat push hidden type vehicle door handle driving device and a method for using the same. BACKGROUND

[0002] The hidden type vehicle door handle is widely used for making the vehicle more streamlined. The current hidden type vehicle door handle comprises a handle body, a driven wheel rod, a driving motor, a driving cam, a driving dial and other components. When the driving motor drives the driving cam to rotate and then drives the driving dial to rotate, the driving dial drives the handle body and the driven wheel rod to rotate in the same direction, thereby pushing out the handle body. When the driving dial drives the connecting fulcrum of the handle body and the driven wheel rod to rotate to the same plane, the driven wheel rod may rotate reversely, which causes the handle body to be pushed out of the surface of the door at one end of the driving dial and the driven wheel rod to be retracted into the surface of the door at the other end, thereby affecting the use.

The upper handle shell and the lower handle shell are combined with each other to cover the handle body in a cavity. The device further comprises a driven wheel rod, a synchronous connecting rod, a driving motor, a reset torsion spring, a driving cam and a driving dial.

[0006] The driven wheel rod and the driving dial are rotatably sleeved at two ends of the handle body, respectively.

[0007] The two ends of the synchronous connecting rod are respectively fixed with a rotating boss. The driven wheel rod is provided with a driven positioning sliding groove. The driving dial is provided with a dial sliding groove and a reset shaft. The rotating boss at one end of the synchronous connecting rod is slidably arranged in the driven positioning sliding groove of the driven wheel rod, so that the synchronous connecting rod and the driven wheel rod are in dynamic cooperation. The rotating boss at the other end of the synchronous connecting rod is slidably arranged in the dial sliding groove of the driving dial, so that the synchronous connecting rod and the driving dial are in dynamic cooperation.

[0008] The reset torsion spring is sleeved on the reset shaft of the driving dial. The two ends of the reset torsion spring are respectively abutted against the synchronous connecting rod and the driving dial. The dial rotating shaft of the driving dial and the driven rotating shaft of the driven wheel rod are installed in the rotating shaft sleeve of the upper handle shell and the lower handle shell, thereby forming dynamic cooperation. The driving cam is inserted into the driving motor and then inserted into the positioning hole in the lower handle shell according to the positioning boss on the driving motor.

[0009] The flat push hidden car door handle driving device is characterized in that it further comprises a long pin, a lower short pin and an upper short pin,

[0010] A driven pin hole is arranged on the driven wheel rod, one end of the handle body is provided with a handle pin hole, the driven pin hole and the handle pin hole are aligned, the long pin is sequentially inserted into the driven pin hole and the handle pin hole, and the driven wheel rod is rotatably arranged at one end of the handle body.

[0012] The use method of the flat push hidden car door handle driving device is characterized by the following steps:

[0013] Opening the door: when the driving motor drives the driving cam to rotate and drives the driving dial to rotate forward, the driving dial will drive the handle body and the driven wheel rod to rotate in the same direction and push the handle body out in parallel, when the driving dial rotates forward for 30°, the handle body is pushed out of the door surface by 60° through the synchronous connecting rod, and the handle body is pulled to open the door.

[0014] Retracting: conversely, when the driving motor drives the driving cam to rotate and drives the driving dial to rotate reversely, the driving dial will drive the handle body and the driven wheel rod to rotate in the same direction and retract the handle body into the door surface in parallel, when the driving dial reversely rotates for 30°, the handle body is retracted into the door surface by 60° through the synchronous connecting rod.

[0015] The present application adds a synchronous connecting rod, so that the handle body can be pushed out of the door surface in parallel, the user can smoothly open the door, and the handle body can always operate normally.
