BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

2 shows a structure of a vehicle assist handle according to an embodiment of the present invention. Hereinafter, the structure of the automotive assist handle according to one embodiment of the present invention will be described in detail with reference to FIG.

According to Fig. 2, the assist handle includes a handle base, a handle body, a rotary shaft, and a leaf spring. Of course, other configurations than those described above may be included in the assist handle proposed in the present invention.

 As described above, the handle base 200 is installed on the side upper ceiling of the driver's seat or the driver's seat and the rear seat of the vehicle using a connecting member. The handle body 210 is rotatably coupled to the handle base 200 through a rotation shaft 220.

One rotation shaft 220 is provided at each end of the handle body. The handle body 210 must not interfere with the handle base 200 when the handle body 210 rotates with respect to the handle base 200 about the rotation axis 220. Therefore, A concave portion having an arc shape is formed.

The rotation shaft 220 is provided with a return spring having an elastic force so that the handle body 210 can be returned and rotated. The return spring is fixed to the handle base 200 at one end in a state of being wound around the rotation shaft, 210 so that the elastic force of the handle body 210 is returned to the original position.

The assist handle is formed with a leaf spring 210-1 on the handle body 210 and an outer projection 200-1 moving along the leaf spring 210-1 is provided on the handle base 200 . Hereinafter, the structure of the leaf spring formed on the handle body according to the embodiment of the present invention will be described in detail with reference to FIG.

According to Fig. 3, the leaf spring 210-1 forms a protrusion. By forming protrusions on the leaf spring 210-1, the handle body absorbs noise or shock generated by partially reducing the return speed when returning to the original position. That is, when the leaf spring 210-1 is not provided with a protrusion, the return speed of the handle body is increased by the return spring when the handle body is returned by the restoring force of the return spring, do. Therefore, the present invention forms a protrusion in the leaf spring 210-1 in order to keep the return speed generated at the time of returning to be constant. Further, the handle body 210 forms a fixing portion for fixing one end of the leaf spring, and the leaf spring is fixed to the handle body by the fixing portion.

Hereinafter, the shape of the protrusion formed on the leaf spring will be described in detail with reference to FIG. According to Fig. 3, the protrusions formed on the leaf spring are formed so as to have different inclination angles on the left and right sides. That is, when the handle body is returned from the point (a1) to the point (b1) on the fixed handle base, the inclination angle is made different according to the return direction. That is, the inclination angle of the point (a1) relative to the center is relatively larger than the inclination angle of the point (b1). By doing so, the return speed at the point (a1) where the handle body has a relatively steep slope is drastically reduced. Thereafter, the handle body is returned at a speed that is decelerated at the point (b1) that forms a relatively gentle slope. As described above, according to the present invention, the inclination angle of the projections formed on the leaf spring is different from the inclination angle of the projections formed on the center of the plate spring.

FIG. 3 shows a case where one projecting portion is formed on the leaf spring, but the present invention is not limited thereto. That is, at least two protrusions can be formed on the leaf spring. Hereinafter, a case where two projections are formed on the leaf spring will be described.

The two protrusions formed on the leaf spring have different protruding heights. That is, when the handle body is returned from the point (a1) to the point (b1) on the fixed handle base, the protruding height of the protruding portion is made different according to the return direction. The protruding height of the protruding portion located at the front end with respect to the protruding direction is formed to be greater than the protruding height of the protruding portion located at the rear end. By doing so, the handle body is abruptly reduced in its return speed by the protruding portion located at the front end having a relatively large protruding height. Thereafter, the return is made while maintaining the reduced return speed by the protruding portion located at the rear end. That is, if the protruding portion located at the rear end also has the same protruding height, the handle body may not return, or the return time may be increased even if the protruding portion is returned. Therefore, according to the present invention, the protruding height of the protruding portion located at the rear end is relatively lower than the protruding height of the protruding portion located at the front end, so that the return is made while maintaining the reduced return speed.

The inclination of the protrusion located at the front end on the leaf spring and the inclination of the protrusion located at the rear end are formed to be the same or the inclination of the protrusion located at the rear end is formed to be smaller than the inclination of the protrusion located at the front end.

In addition, when two projections are formed on the leaf spring, the projections positioned at the rear end can be formed only on one side, and the outer projections formed on the handle base end the return from the projections formed only on one side.

4 illustrates a shape of an outer protrusion formed on a handle base according to an embodiment of the present invention. Hereinafter, the shape of the outer protrusion formed on the handle base according to the embodiment of the present invention will be described in detail with reference to FIG. According to Fig. 4, the handle base forms one outer projection 200-1.

However, the handle base can form two outer protrusions having different heights. The height of the outer projection depends on the direction in which the handle body rotates on the fixed handle base. That is, the height of the outer protrusion located at the front end relative to the direction in which the handle body returns from the fixed handle base is formed to be relatively higher than the height of the outer protrusion positioned at the rear end. By forming the outer protrusion located at the front end relatively high in this manner, the return speed generated when the handle body returns can be reduced.

The handle base may form only one outer protrusion, in which case at least two protrusions may be formed on the handle base to reduce impact or noise upon return.

According to the present invention, the leaf spring is integrally coupled to the handle body by insert injection into the handle body. That is, the leaf spring is manufactured, and then the leaf spring is inserted into the mold and the insert is injected, or the handle body and the leaf spring are manufactured and then assembled using ultrasonic waves.

Therefore, the present invention does not use a separate coupling member for coupling the handle body and the leaf spring, thereby reducing the cost and weight. Of course, the handle body and the leaf spring can be coupled using a separate coupling member.

In addition, the surface of the outer projection of the present invention can perform the embossing treatment.

5 illustrates an example in which a handle body having a leaf spring is moved on a handle base having an outer protrusion according to an embodiment of the present invention.

Fig. 5 (a) shows an initial time point at which the handle body moves back and forth on the handle base, and Fig. 5 (b) shows the end point when the handle body moves back on the handle base.

As shown in Fig. 5 (a), at the initial point of time when the handle body moves on the handle base and returns, the return speed is reduced by the protrusion located at the front end of the handle body located at the front end.

Referring to FIG. 5 (b), the handle body having the reduced return speed returns to the original position with the return speed reduced by the protruding portion located at the rear end maintained without newly increasing.

In addition, according to the present invention, when the leaf spring is composed of two protrusions, it is possible to reduce the noise while improving the return speed of the handle body by designing that the outer protrusions formed on the handle base do not touch between the both ends of the protrusions.

Although the present invention has been described with respect to assist handles, it is not limited thereto. The present invention can be similarly applied to a vehicle coat hanger formed inside a vehicle. That is, a coat hanger base fixedly installed on a panel of a vehicle and having a coat hanger base on which an outer projection is formed and a plate spring on which the outer projection is moved and formed with protrusions is rotatably coupled to the coat hanger base about a rotation axis, The present invention is equally applicable to a vehicle coat hanger including a vehicle hanger.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention .
