Description

Door handle overload protection structure

Technical Field

The utility model belongs to the technical field of car door handle, a door handle overload protection structure is related to.

Background

The door handle of prior art, overall structure is complicated, and product accessories and assembly process are loaded down with trivial details, and structural reliability is poor to can take place the door handle function loss and lead to the people to fly out in the carriage when the vehicle receives the impact, holistic security is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem to prior art's current situation, and provide a structural reliability is good, has reduced the door handle overload protection structure of the cost of product.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the door handle overload protection structure is characterized by comprising a rotating shaft, a torsional spring and a functional block, wherein the functional block is installed on a door handle body, a guide hole shaft is arranged on the functional block, the rotating shaft penetrates through the guide hole shaft, the torsional spring is installed at the end part of the guide hole shaft and controls the rotating shaft to rotate, and a maintaining matching component is arranged between the functional block and the door handle body.

In the above overload protection structure for the door handle, the retention fitting assembly includes a retention rod and a limiting groove, the retention rod is integrally formed with the functional block, the limiting groove is located on the door handle body, the functional block and the door handle body have a hinged end, and the functional block can move around the hinged end and enable the retention rod to be inserted into the limiting groove.

In foretell door handle overload protection structure, the function block on have the caulking groove, have in the caulking groove and support and lean on the mouth, the torsional spring is whole to be located the caulking groove and overlap the tip at the rotation axis, the one end of torsional spring is hung and is being supported and lean on a mouthful department.

Compared with the prior art, the utility model has the advantages of reduced the accessory, reduced the assembly flow, low in manufacturing cost checks and CAE simulation through the motion, has ensured that the car is under the impact, and the door handle function loss leads to the people to fly out from the carriage.

FIG. 3 is a schematic view of the structure in the direction of C-C.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

In the figure, a rotating shaft 1; a torsion spring 2; a function block 3; a door handle body 4; a pilot hole shaft 5; a caulking groove 6; an abutment port 7; a holding rod 8; a limiting groove 9; a hinged end 10.

As shown in figures 1 and 2, the overload protection structure of the door handle comprises a rotating shaft 1, a torsion spring 2 and a functional block 3, wherein the functional block 3 is installed on a door handle body 4, a guide hole shaft 5 is arranged on the functional block 3, the installation direction of the rotating shaft 1 can be ensured through the guide hole shaft 5, the rotating shaft 1 passes through the guide hole shaft 5, the torsion spring 2 is installed at the end part of the guide hole shaft 5 and controls the rotating shaft 1 to rotate, an embedding groove 6 is arranged on the functional block 3, an abutting opening 7 is arranged in the embedding groove 6, the torsion spring 2 is integrally arranged on the embedding groove 6 and sleeved at the end part of the rotating shaft 1, one end of the torsion spring 2 is hung at the abutting opening 7, the embedding groove 6 mainly has the function of facilitating the installation of the torsion spring 2, so that the torsion spring 2 ensures the stability of position installation, because the torsion spring 2 is sleeved on the rotating shaft 1 and hung at the abutting opening 7, and because the rotating shaft 1 passes through the functional block 3, the functional block 3 can be driven to move, as shown in figure 3, the biggest innovation of the patent is that a maintaining and matching component is arranged between the functional block 3 and the door handle body 4, the maintaining and matching component comprises a maintaining rod 8 and a limiting groove 9, the maintaining rod 8 and the functional block 3 are integrally formed, the limiting groove 9 is positioned on the door handle body 4, the functional block 3 and the door handle body 4 are provided with a hinged end 10, the functional block 3 can move around the hinged end 10 and enables the maintaining rod 8 to be inserted into the limiting groove 9, the door handle body 4 can normally work in a normal working state and rotates within a range along the rotating shaft 1 to open and close the door, when the vehicle is impacted laterally, the functional part retaining rod 8 can be inserted into the limiting groove 9 due to the inertia effect inside the vehicle, so that the risk of throwing away a driver from the vehicle due to opening of the functional part retaining rod is avoided.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
