Description

Handle automatic re-setting mechanism and hidden handle

Technical Field

The utility model relates to the technical field of automobile parts, in particular to an automatic handle resetting mechanism and a hidden handle.

Background

At present, with the improvement of living standard of people, the dependence degree on automobiles is more and more obvious, and the requirements on the appearance and the function of automobile parts are higher and higher. The automobile outer handle is an important component of an automobile door system, and the traditional outer handle assembly parts mainly comprise an outer handle, an outer handle cover, an outer handle bracket, an outer handle connecting rod, an automobile door lock cylinder and other parts.

Most automobile door handles of automobiles are designed in an exposed and convex mode, and the design needs to consider that the shape of the automobile door handle needs to be matched with the side face of an automobile body so as to ensure good appearance, so that a plurality of limitations are caused; on the other hand, the inside and the outside of the door outer handle are easily polluted because the door outer handle is wholly exposed, and the driver easily gets dirty when opening the door. And the outer door handle protrudes outwards, so that the side surface appearance of the whole automobile is damaged, a certain wind resistance is caused, the running resistance of the automobile is increased, and the wind noise is increased. To this end, many manufacturers have developed handle designs that create retractable hidden handles. In order to solve the above problems, some manufacturers have introduced a hidden type automobile outer handle. The hidden type automobile outer handle generally has three states, namely an initial hidden state, a pre-unfolding state and a fully unfolding state.

The handle part of the existing hidden handle has a quite single reset structure, as in the utility model of patent document CN111827810A, which discloses a hidden automobile outer door handle assembly, comprising a base, a handle and a driving device, wherein one end of the handle rotates around a first connecting shaft relative to the base, so that the handle can be switched between a hidden position and an extended position relative to the base; the driving device is used for driving the handle to move from the hiding position to the extending position. The drive device includes: the electromagnetic catapult comprises a catapult shell, a movable iron core and an induction coil, wherein the induction coil surrounds the movable iron core, and the induction coil controls the on-off of the induction coil through a vehicle control center; the connecting rod is connected to the base in a rotating mode around the second connecting shaft, one end of the connecting rod is connected to one end of the movable iron core in a transmission mode, the other end of the connecting rod is connected to the handle in a transmission mode, when the induction coil is powered on, the movable iron core outwards pops out along the length direction of the ejector shell and pushes the connecting rod to rotate, and the connecting rod pushes the handle to pop out of the outer surface where the car door is located. The hidden type automobile outer door handle assembly further comprises a handle resetting elastic piece, one end of the handle resetting elastic piece is connected to the base, the other end of the handle resetting elastic piece is connected to the handle, and after the induction coil is powered off, the handle is reset under the elastic force of the handle resetting elastic piece.

It can be seen that, among the hidden automobile-used door handle of current, in order to realize the handle and reset, all establish handle elastic component that resets (torsional spring) on the connecting axle of handle and handle base cover, compress handle elastic component that resets (torsional spring) during the use, realize the handle through the elasticity that handle elastic component that resets (torsional spring) gathered behind the pine hand that the handle resets and resets. Such handles have at least the following disadvantages: the handle moves in the horizontal direction, so that the torsion spring is vertical to the handle; if the force of the torsion spring is set to be small, the handle can be reset slowly or even cannot be reset in place; if the torsion spring force is set to be large, the handle is reset too fast and even collision damage is easy to occur. After the torsion spring is repeatedly used, the torsion spring is easy to fatigue, so that the reliability of the handle during resetting is poor, and the torsion spring is easy to break down and even cannot be normally used; the hidden handle at least has an initial position state, a pre-expansion position state and an unlocking position state, and in the prior art, if the hidden handle is required to be kept in the pre-expansion position state, the actuator part is required to continuously work to provide position support for the handle main body, so that the load of the actuator is increased, and a user can manually close the handle main body reversely during the use process, which easily causes the damage of the actuator.
