Description

Technical Field

[0001] The utility model relates to the technical field of air deflector covers, in particular to a split air deflector cover. Background Art

[0002] A shroud is an exterior component mounted on the front of a car, truck or van to improve the vehicle's aerodynamics. It is designed to allow air to flow smoothly over the vehicle, reducing drag, improving fuel economy and increasing stability.

[0003] Most of the existing air deflectors are made of an integrated structure. During the driving process of the vehicle, if the outer surface of the air deflector collides with other objects or is affected by strong wind, there is a possibility that the air deflector will be deformed and damaged, affecting the operation and maintenance stability of the air deflector. In addition, since the air deflector is in an external state for a long time and is affected by factors such as wind and sun, after long-term use, the surface of the air deflector will be covered with dust, dirt and other substances, resulting in obstruction of airflow and reducing the operating effect of the air deflector. Utility Model Content

[0004] In view of the above technical problems existing in the application of the existing air deflector, the utility model provides a split air deflector.

[0005] A split type air deflector, comprising an air deflector body, a base is arranged at the bottom end of the air deflector body, a deflector plate is arranged above the base, one end of the deflector plate is hingedly arranged with the base through a hinge, a notch is provided on the inner wall of the base to fit one end of the deflector plate, and one end of the deflector plate is elastically connected with the notch through an elastic connector;

[0006] Baffles are respectively arranged on the side walls of both sides of the base, a sliding groove is opened on the inner wall of the baffle, a scraper is slidably connected in the sliding groove, the middle section of the scraper is located on the surface of the guide plate, and a driving member is arranged at one end of the scraper, and the scraper is driven to slide along the surface of the guide plate by the driving member.

[0007] Furthermore, the hinged member includes a bolt, which is inserted into a through hole preset on the side wall of the base, and one end of the bolt is threadedly connected to a threaded hole preset on one side wall of the guide plate.

[0008] Furthermore, the elastic connecting member includes an airbag spring and a compression spring, the airbag spring is arranged at the bottom of one end of the guide plate, one end of the compression spring is threadedly connected to one end of the airbag spring through a preset connecting seat, and the other end of the compression spring is threadedly connected to the inner wall of the slot through a preset connecting seat.

[0009] Furthermore, the driving member includes a cylinder, which is arranged in one end of the slide groove, and the telescopic rod of the cylinder is fixedly connected to one end of the scraper, and the scraper is driven by the cylinder to slide along the slide groove.

[0010] Furthermore, a scraper strip is provided at one end of the scraper plate close to the surface of the guide plate, and the operating end of the scraper strip abuts against the surface of the guide plate.

[0011] Beneficial effects of the utility model:

[0012] 1. The deflector is hinged to the base through bolts, so that the base and the deflector form a split deflector body operating structure. When the deflector body is traveling with the vehicle, when the deflector is affected by wind resistance, it rotates around the bolts, thereby driving the airbag spring to be compressed, so that the compression spring is elastically deformed under force, and the deflector is tilted at a certain operating angle, so that the operating tilt angle can be adjusted according to the force of wind resistance, so as to avoid the deflector body being subjected to wind resistance exceeding the upper limit it can withstand during operation. In addition, when the vehicle accidentally hits an external object, such as a branch or a railing, the deflector is hinged by the compression spring and deflected toward the slot to reduce the possibility of rigid contact between the deflector and the external object, thereby further avoiding deformation and damage to the deflector of the deflector body, thereby improving the operational stability of the deflector body, and when the deflector is accidentally damaged, the split design of the deflector and the base allows only the deflector to be removed for replacement, thereby saving costs and facilitating replacement and maintenance.

[0013] 2. The scraper is driven to move along the slide groove by the telescopic rod of the cylinder, thereby driving the scraper strip in the middle section of the scraper to slide along the surface of the guide plate. Then, through the contact between the scraper strip and the surface of the guide plate, it is convenient to remove the dirt, dust and other debris attached to the surface of the guide plate, avoid airflow obstruction, improve the working effect of the guide cover body, and ensure a good working state.
