Example Embodiment

[0038]Example one

[0039]Please refer toFigure 1 to 4As shown, the present embodiment provides an automotive active intake grid limit structure, which includes a first constituent mechanism 1 disposed on the active intake grid body 3 and the active blade 4 The second restricted mechanism 2, wherein the first constituency mechanism 1 is mounted to the active blade 4 mounting hole position, which is used to limit the active blade 4 to turn on and turn off the limit, and the active blade drive shaft passes through the initiative. The gas gate body 3 is mounted in the hole and connected to the drive mechanism (not shown) through the spline 26 on the drive shaft, the drive mechanism can select the existing drive motor, and keep the active blade 4 before the drive motor is powered on, not closed. Of course, other drive mechanisms can be used to drive the drive shaft to rotate to drive the active blade 4 to switch to turn off state and open state.

Example Embodiment

[0046]Example 2

[0047]Embodiment 2 is the same as that of the examples, and the difference is: bondingFigure 9 withFigure 10 As shown, the present embodiment provides an automotive active intake grid limit structure, in the illustrated embodiment, the present technical solution is still in consideration of the active blade 4, in order to ensure that the assembly is last long. The sealing performance will restrict the active blades 4 in the closed state of the resin layer 52, that is, the present embodiment is at least one layer on the hardenening layer 51 of the limit ribs A21 and the limit rib C23. When the base, the active blade 4 is in a closed state, the limit ribs A21 and the first restricted segment A112 and the limit rib C23 are always in contact with the first residential segment B121 to ensure in this state. The lower first restricted mechanism 1 and the second constituent mechanism 2 are flexible contact, so that in the case where the active blade 4 is deformed, the drive m...

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...
