Embodiment 1

[0039] Please refer to Figure 1 to Figure 4 As shown, this embodiment provides a limiting structure for the active air intake grille of an automobile, the limiting structure includes a first limiting mechanism 1 arranged on the active air intake grille body 3 and a first limiting mechanism 1 arranged on the active blade 4 Two limit mechanisms 2, wherein the first limit mechanism 1 is installed on the active air intake grille body 3 near the installation hole of the active vane 4, and is used to limit the opening and closing limit positions of the active vane 4, and the drive shaft of the active vane passes through the active intake The air grille body 3 is installed in the installation hole and is connected with the drive mechanism (not shown) through the spline 26 on the transmission shaft. The drive mechanism can be selected from the existing drive motor. Before the drive motor is powered on, keep the active blade 4 in an unclosed state Of course, other driving mechanisms c...

Embodiment 2

[0047] Embodiment two is basically the same as embodiment one, and its difference is: combine Figure 9 and Figure 10 As shown, this embodiment provides a limiting structure for the active air intake grille of an automobile. In the illustrated embodiment, this technical solution still takes into account the deformation of the active blade 4, in order to ensure that the product lasts for a long time after assembly. For sealing performance, a layer of soft rubber layer 52 is provided for the limiting ribs that limit the active blade 4 to be in the closed state, that is to say, in this embodiment, at least a layer of soft rubber is provided on the hard rubber layer 51 of the limiting ribs A21 and C23. Adhesive layer 52, so that when the active blade 4 is in the closed state, the limiting rib A21 and the first limiting section A112 and the limiting rib C23 and the first limiting section B121 are always in contact with each other through the soft rubber layer 52, so as to ensure t...

Abstract

The invention discloses an automobile active air-inlet grille limiting structure, which relates to the technical field of automobile active air-inlet grilles, and comprises a first limiting mechanism arranged on an active air-inlet grille body and a second limiting mechanism arranged on an active blade, wherein the first limiting mechanism is mounted at the position, close to a driving blade mounting hole, of the driving air-inlet grille body, is used for limiting the opening and closing limit position of a driving blade, and comprises a limiting part A and a limiting part B which are arranged in an axial symmetry manner; the second limiting mechanism is mounted on the driving blade transmission shaft, is correspondingly arranged between the limiting part A and the limiting part B, and can limit the driving blade to rotate to be in a closed state and limit the driving blade to rotate to be in a fully open state; by means of the structure, the starting point position and the ending point position of the blades in the rotating process can be accurately controlled, the sealing face of the driving blade is made to make complete contact with the sealing face of the grille body, and the problem that existing automobile driving grille similar products are poor in blade sealing is solved.

Description

technical field [0001] The technical field of the automobile active air intake grille of the present invention, in particular, relates to a limiting structure of an automobile active air intake grille. Background technique [0002] With the increasing requirements for energy saving, emission reduction and fuel consumption, the active air intake grille of automobiles will become the standard configuration of more and more mid-to-high-end models. air volume and wind resistance, so as to improve fuel economy and quickly reach the best operating temperature of the engine; the active air intake grille of the car is generally located under the hood of the car, behind the grille of the car, and directly in front of the engine compartment. The traditional air intake grille is fixed The shutters are opened, and the active air intake grille is a shutter that can control the opening and closing angle. It can intelligently control the motor on the active air intake grille to achieve the...
