Description

Technical Field

[0001] The utility model belongs to the field of automobiles, is mainly applicable to city buses and buses for other purposes, and specifically relates to a compartment air induction device for buses. Background Art

[0002] With the development of new energy vehicles, new energy buses have become a mainstream product in the current bus industry. Pure electric buses, in particular, are gaining popularity among consumers, with increasing demands for range and battery capacity, often requiring high battery capacity and long driving range. New energy buses are often equipped with electric air conditioning, and power consumption is a key factor affecting their range. When the air conditioning is running, the cabin experiences uneven cooling, with the top of the cabin feeling hot and the bottom cold. To ensure adequate cooling and heating in the lower cabin, the air conditioning's cooling and heating capacity are typically increased, which in turn increases power consumption. To reduce power consumption, bus manufacturers have exhausted various methods to optimize power consumption or improve cabin sealing, but the results have been subpar. Utility Model Content

[0003] The purpose of the utility model is to provide a passenger car compartment air induction device to solve the problem of hot head and cold feet in the car and uneven heating and cooling when the air conditioner of the new energy passenger car is running, thereby reducing the power consumption of the air conditioner.

[0004] The technical solution adopted by the utility model is a passenger car compartment air induced draft device, comprising air induced draft ducts, wherein a plurality of air induced draft ducts are arranged on the left and right sides of the vehicle body along the vehicle length direction, the top ends of the air induced draft ducts are connected to the air conditioning ducts installed between the side walls of the vehicle body ceiling, and the bottom ends of the air induced draft ducts are connected to the air outlet hood, which is installed on the vehicle body floor.

[0005] Preferably, one end of the air-conditioning duct is installed on the roof of the vehicle body, and the other end is installed on the semi-elliptical structure of the vehicle side wall. Multiple air outlets are arranged on the curved surface of the semi-elliptical structure. The air duct is a square cavity structure with open upper and lower end faces. The top of the air duct is connected to some air outlets of the air-conditioning duct, and the lower end face of the air duct extends into the air outlet hood.

[0006] Preferably, the upper end surface of the air duct is provided with a mounting hole, and the fan is mounted on the top of the air duct through the mounting hole with the air outlet facing the lower part of the air duct.

[0007] Preferably, the above-mentioned air outlet hood is a semi-open box structure installed between the vehicle body floor and the vehicle body side wall, an opening is provided on the upper end surface of the air outlet hood, the lower end surface of the air duct is embedded into the interior of the air outlet hood through the opening, and multiple groups of heat dissipation holes are provided in the front, rear and front of the air outlet hood.

[0008] Compared with the existing technology, the beneficial effect of the present invention is that by arranging multiple sets of air ducts on the left and right side walls of the car body, the cold and warm air in the air-conditioning duct is transported to the floor of the car body, and then the cold and warm air of the air-conditioning is dispersed to the bottom of the car body through the air outlet cover, so as to solve the problem of hot head and cold feet and uneven temperature between the upper and lower parts of the car body.

[0014] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.

[0015] Example 1

[0016] like Figure 1-5 As shown, a passenger car cabin air induced draft device includes a vehicle body 1, an air conditioning duct 2, a fan 3, an air induced draft duct 4 and an air outlet cover 5. The vehicle body 1 is the main body of the passenger car, including a roof, side walls, a floor and other parts, and is an installation carrier for the air conditioning duct 2, the air induced draft duct 4 and the air outlet cover 5.

[0017] The air conditioning duct 2 is the outlet for the bus's electric air conditioner. It has a semi-elliptical structure with one end mounted on the ceiling of the vehicle body 1 and the other on the side wall. Multiple air outlets 201 are located on the curved surface of the semi-elliptical structure. Some of these outlets 201 connect to the air duct 4, which then flows through the outlets 201 and into the air conditioning duct 2. The air conditioning duct 2 is constructed of aluminum alloy or extruded non-metallic material.

[0018] The ducts 4 are hollow structures with open top and bottom surfaces. Multiple ducts 4 are located on the left and right sides of the vehicle body 1 along the vehicle's length. The top surfaces of the ducts 4 are provided with multiple circular holes for mounting the fans 3. The bottom surfaces of the ducts 4 are embedded within the hood 5 through openings 501. The ducts 4 are welded metal components or extruded non-metal components. They can be secured to the side walls of the vehicle body 1 by welding, riveting, screwing, or other methods.

[0019] The fan 3 is a common small fan on the market. Its lower end face is a mounting base 301. There are multiple mounting holes on the lower end face. The mounting holes correspond one-to-one with the circular holes on the air duct 4. It is fixed to the upper end face of the air duct 4 with bolts and the air outlet faces the lower part of the air duct 4.

[0020] The air hood 5 is a semi-open box structure installed between the floor of the vehicle body 1 and the side wall of the vehicle body 1, with the front, top, front and back sides closed. An opening 501 is provided on its upper end face. The lower end face of the air duct 4 is embedded into the interior of the air hood 5 through the opening 501 provided on the air hood 5. A plurality of heat dissipation holes 502 are provided on the front, back and front sides of the air hood 5. The hot and cold air of the air conditioner is pressurized by the fan 3 through the air conditioning duct 2, and then transported to the interior of the air hood 5 through the inner cavity of the air duct 4, and finally dispersed to the bottom of the car through the heat dissipation holes 502, thereby solving the problem of the head being hot and the feet being cold, and the uneven temperature between the top and the bottom of the car. The air hood 5 is an aluminum alloy part or an extruded non-metallic part.
