Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to an air intake device of a tire protective cover, a tire protective cover and an automobile. Background Art

[0002] Excessive temperatures of the engine and brakes can cause damage to the car. Excessive temperatures of the brakes and slow cooling speeds can easily cause thermal decay of the brakes. Due to thermal decay of the brake disc or damage to the brake components by high temperature, brake failure has caused countless traffic accidents. 85% of traffic accidents involving brake failure are caused by thermal fatigue damage of the brakes. To prevent the brake temperature from being too high, the car is designed to guide the airflow to the brake disc. Many cars use fender vents to improve the cooling performance of the engine and brakes, but for cars that are restricted by the shape and cannot set the vents on the fenders, how to set vents on the tire guard has become a problem. The main function of the tire guard is to effectively prevent the dirt, stones, rain and snow brought up by the vehicle tires during the rotation process; protect the parts inside the car body and prevent foreign objects from entering the cabin; reduce the appearance of noise; and meet the needs of aesthetics at the same time. Vents or grilles are set on the tire guard. If the number of vents and grilles is too few or too small, it will hinder the entry of cooling airflow and cannot meet the cooling needs of the engine and brakes. If the number of vents and grilles is too large or the opening is too large, it will affect the protective effect of the tire guard, and foreign objects such as sand, gravel, rain and snow will easily enter the cabin and cause damage to the internal parts of the car body. Summary of the invention

[0003] The purpose of the utility model is to provide an air intake device for a tire protective cover, a tire protective cover and a car, wherein a window-type air intake assembly is arranged on the tire protective cover, and the opening and closing of the air intake baffle of the air intake assembly is controlled by a motor assembly to solve the above-mentioned technical problems.

[0004] The specific contents of the plan are as follows:

[0005] An air intake device for a tire protective cover comprises a motor assembly and a window-type air intake assembly. The motor assembly is connected to the window-type air intake assembly, and the opening and closing of the window-type air intake assembly is controlled by the motor assembly.

[0006] The air intake device of the tire protective cover includes a motor assembly and a window-type air intake assembly. The motor assembly is rotatably connected to the window-type air intake assembly, and the motor assembly controls the opening and closing of the window-type air intake assembly. During the driving process of the vehicle, the external environment and temperature are detected by the sensor, and the sensor feeds back the information to the body controller of the vehicle, and the body controller issues a power-on command to the engine control unit. When the weather is too hot, the temperature of the engine and the brake is too high, and the cooling speed is slow, the body controller sends a signal command to the motor assembly, the motor is powered on and starts to work, and the rotor output shaft of the motor rotates to control the full opening of the window-type air intake assembly, increase the intake volume, and achieve the purpose of rapid cooling. When the temperature is low, the temperature of the engine and the brake is normal, and the intake volume does not need to be increased, the body controller sends a signal command to the engine control unit, the motor assembly receives the command, and the motor rotates to control the window-type air intake assembly to close, which can better play the protective role of the tire protective cover and prevent foreign objects from entering the cabin and damaging the internal parts of the body.

[0007] Furthermore, the window-type air intake assembly includes a frame and an opening and closing structure. The frame is rectangular, and the opening and closing structure is rotatably connected to the frame.

[0008] The window-type air intake assembly includes a frame and an opening and closing structure. The overall shape of the frame is rectangular.

A plurality of first mounting holes and semi-circular arc covers are symmetrically arranged on the inner walls of the two longitudinal frames and on the left and right outer walls of the partition, and the semi-circular arc covers are arranged in front of the corresponding first mounting holes.

[0012] The frame is a rectangular frame consisting of a horizontal frame and a longitudinal frame. The air intake device of the tire protective cover can be a single-window structure or a multi-window structure, which is set according to actual needs. Taking the two window-shaped structures as an example, a longitudinal groove-shaped partition is also provided in the middle of the frame, and the rear end of the partition is open. The partition divides the frame into two window-shaped structures. On the inner side walls of the two longitudinal frames and on the left and right outer side walls of the partition, a plurality of first mounting holes and semi-circular arc covers are spaced and symmetrically arranged, and the positions of the symmetrically arranged first mounting holes are highly consistent. The semi-circular arc cover of the first mounting hole is arranged on the corresponding first mounting hole. The semi-circular arc cover of the first mounting hole is arranged in front of the corresponding first mounting hole, and the opening faces backward. The function of the semi-circular arc cover is to limit the blades and to block the gap between the blades and the partition, so that the entire air intake device can be completely closed when the blades are closed, thereby preventing foreign objects from entering the fuselage and causing damage to parts.

[0013] Furthermore, the opening and closing structure includes two groups of rotating components, which are respectively arranged in the corresponding frames on the left and right sides of the partition. The motor controller is fixedly connected to the groove structure of the partition. The motor controller includes two rotor output shafts arranged on the left and right, and the two rotor output shafts are respectively rotatably connected to the corresponding rotating components on the same side.

[0014] The opening and closing structure includes two sets of rotating components.
