Embodiment Construction

[0038] Specific embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0039] It should be noted that, in the case of no conflict, the embodiments in the application and the technical features in the embodiments can be combined with each other. Undue Limitation of This Application.

[0040] It should be understood that the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings. These orientation terms are only for the convenience of describing the application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the application.

[0041] Generally speaking, if Figure 11 As shown, the cooling fan of the car is forcibly dissipating heat from the radiator, but when the...

Abstract

The invention discloses a cowl for a vehicle, the cowl comprises a cowl body and a wind shield assembly, the cowl body is provided with a via hole, a rotation center and a ventilation hole for mounting a fan, the wind shield assembly is mounted at the rotation center, the wind shield assembly is rotatably connected with the cowl body, and the rotation center is perpendicular to the cross section of the via hole. When the vehicle speed is lower than a preset value, the wind shielding assembly covers the via hole, and when the vehicle speed is larger than or equal to the preset value, the wind shielding assembly rotates around the rotation center to open the via hole. The invention further discloses a fan assembly for the vehicle, the fan assembly comprises the fan protection cover and a fan assembly, and the fan assembly is installed in the ventilation hole. The rotating center is perpendicular to the cross section of the via hole, and the wind shielding assembly can rotate around the rotating center, so that the arrangement space required by rotation of the wind shielding assembly is reduced, the space utilization rate of the wind shield is improved, and meanwhile, the risk of noise generated in the process of closing or opening the via hole by the wind shielding assembly is reduced.

Description

technical field [0001] The present application relates to the technical field of vehicle cooling fans, in particular, to a windshield and fan assembly for vehicles. Background technique [0002] The main function of the automobile engine cooling system is to dissipate the heat generated by the engine during operation into the air to prevent the engine from overheating and keep the engine at a suitable working temperature. The automobile engine must be properly cooled in a high-temperature working environment in order to keep it working at a suitable temperature to meet the requirements of good engine performance, durability and exhaust emissions. [0003] Currently, if Figure 11 As shown, the cooling fan basically includes a fan guard 5 installed on the radiator and fan blades A, and the fan blades A are vertically arranged. When the fan blade A is closed, the fan blade A collides with the fan guard 5 and generates noise. At the same time, the fan blade A takes up a large...
