Description

Technical Field

[0001] The utility model relates to a structural improvement of an automobile air intake grid. Background Art

[0002] The vehicle's air intake grille is located at the front end of the engine compartment. When the vehicle is driving, fresh air enters the interior through the air intake grille to provide the necessary air for the cooling system. With the rapid development of automobile technology, with the development of aerodynamics, especially for new energy electric vehicles, the cruising range is an important indicator. Therefore, the air intake grille must not only help with temperature control, but also be able to reduce wind resistance. According to the needs of different driving times of the vehicle, the air intake grille is actively opened or closed to improve the aerodynamic performance of the car, reduce the drag coefficient, and increase the cruising range.

[0003] At present, the active air intake grille on the market is mainly composed of a blade structure composed of several blades arranged in fixed positions. During driving, the front air intake is actively controlled by turning the blades to open and close. This has a large wind resistance, and when closed, it does not have a self-locking function, and an additional locking mechanism needs to be set to prevent it from being blown by the incoming wind.

[0006] A structural optimization design of a fixing frame, the fixing frame comprises two mounting posts, the mounting posts are integrally arranged on both sides of the rear end of a main frame, and the fixing frame is fixed on the mounting posts.

[0007] Further preferably, the fixing frame includes a connecting portion at the upper end and two connecting rod portions, the connecting portion of the fixing frame is fixed to a fixing frame mounting portion on the mounting column; the fourth rod tail end hinge point is located at the tail end of the connecting rod portion, and the fourth rod is hinged to the fourth rod tail end hinge point.

[0008] The four-bar linkage mechanism is preferably configured such that a first rod tail hinge point is disposed at the end of the mounting column, and the tail end of the first rod is hinged to the first rod tail hinge point of the mounting column.

[0009] The installation position of the electric push rod is optimized, and a push rod mounting frame is provided at the lower part of the main frame, and the fixed end of the electric push rod is hinged on the push rod mounting frame.

[0010] A thrust structure of an electric push rod is preferred, wherein a ball head at a movable end of the electric push rod is connected to a first rod body.

[0013] When the utility model is in use, the integral blades are controlled by a four-bar linkage, and the four-bar linkage is controlled by an electric push rod, forming a closed-loop stable motion mechanism. Driven by the electric push rod, the integral blades can be conveniently moved to cover and open the air inlet. At the same time, combined with the self-locking characteristics inside the electric push rod, there is no need to set an additional locking mechanism.

[0014] The beneficial effects of the utility model are as follows: 1. The single-piece blade has low wind resistance when folded and has higher strength. 2. By adding two mechanisms with locking force to the motion mechanism without locking force, the motion mechanism without locking force uses a four-link to meet the direction of the overall blade opening, and the locking force uses the self-locking force of the electric push rod to meet the locking force of the entire mechanism. This product not only meets the opening method requirements, but also meets the effect of blade stability. BRIEF DESCRIPTION OF THE DRAWINGS
