Description

Concealed automobile outer door handle

Technical Field

The utility model relates to the technical field of automobile handles, in particular to a flat-out hidden automobile outer door handle.

Background

In the prior art, the flat handle generally adopts the executor to promote the push rod, then the push rod promotes the structural style of first swing arm and second swing arm motion, like the patent of patent No. 2019203504821, just so need reserve the space of push rod and set up the gliding slide that supplies the push rod, on the one hand occupation space is great like this, whole handle subassembly is thicker, on the other hand, the push rod width is great, and need set up the higher slide of precision on the base member, the part cost is higher with processing cost, and if block into behind the ice-cube or other foreign matter between handle and the panel beating after the handle is expanded, the handle only relies on the reset of torsional spring to realize the very difficult realization reset this moment, influence the normal work of handle.

Disclosure of Invention

In order to solve the problem that the handle is difficult to reset after foreign matters are clamped between the handle and the sheet metal of the vehicle door in the prior art, the utility model provides the flat-out hidden type automobile outer door handle capable of realizing electric reset.

The technical scheme adopted for solving the technical problems is as follows:

a flush hidden automotive outside door handle comprising:

a base body, a first swing arm and a second swing arm are rotatably connected on the base body,

the first end of the handle body is hinged with the first swing arm, the second end of the handle body is connected with the second swing arm,

the actuator is arranged to be coupled to the actuator,

the eccentric driving part is connected with the output end of the actuator and synchronously rotates, and contacts with the first swing arm and drives the first swing arm to swing;

a middle connecting part, one end of which is connected with the first swing arm, the other end of which is connected with the second swing arm,

the elastic reset mechanism is connected with the first swing arm and/or the second swing arm and is used for driving the handle to reset;

and the reset driving part and the elastic driving part drive the handle main body to reset by a first set stroke together in the reset process, and then the elastic reset mechanism independently drives the handle main body to reset by a second set stroke. The first setting stroke has great restoring force, can press from both sides garrulous with outside ice-cube or other foreign matter, then the rethread torsional spring of remaining second setting stroke rethread resets, and the restoring force is less this moment, prevents that the great restoring force clamp that electronic resets from damaging situations such as finger from taking place.

Further, the reset driving part is connected with the first swing arm. The reset driving mechanism can drive the first swing arm when the first swing arm starts to reset, or can drive the swing arm after the first swing arm resets for a short period of time, so long as the gap between the handle main body and the door sheet metal can be larger than the thickness of the fingers of a human hand when the first set stroke is finished, and the function of clamping broken foreign matters is realized under the condition of safe use.

Further, the drive portion that resets include eccentric connecting rod, eccentric connecting rod one end rotate and connect on eccentric drive portion, eccentric connecting rod center of rotation is eccentric to the center of rotation of eccentric drive portion, is equipped with the arc hole on the first swing arm, eccentric connecting rod other end slip sets up in the arc hole, and when the first swing arm was expanded completely, eccentric connecting rod tip was close to the tip in the arc hole of first swing arm, and along with eccentric drive portion counter-rotating, eccentric connecting rod supported at the tip in arc hole and driven first swing arm and reset.

Further, the eccentric driving part is provided with a curved surface, the first swing arm is provided with an inclined surface, the curved surface is contacted with the inclined surface, and when the eccentric driving part rotates, the curved surface drives the first swing arm to rotate.

Further, the curved surface includes at least a cam surface.

Further, the eccentric driving part is also provided with a plane, and when the handle is in a hidden state, the plane is abutted with the inclined plane of the first swing arm, and the plane and the cam surface are in smooth transition.
