Description

Technical Field

[0001] The present invention relates to the field of energy conservation, and in particular to an air-conditioning auxiliary system for a bus. Background Art

[0002] Buses use fuel to generate electricity, which powers their air conditioners. However, air conditioning is a mechanical process, requiring the conversion of electrical energy into mechanical energy. Buses are bulkier than cars and are typically rectangular, so their design doesn't take into account the impact of air resistance on speed.

[0003] The principle of bus cooling is to use a compressor to compress the refrigerant, turning it into a liquid state while releasing a large amount of heat, causing its temperature to rise significantly. The refrigerant then transfers heat to the outside world through a heat-conducting surface. The heat released by the refrigerant is then transferred to the outside world through pressure reduction, causing the refrigerant to vaporize, absorbing a large amount of heat as it vaporizes. The refrigerant then comes into contact with the air inside the vehicle through another heat-conducting surface, absorbing a large amount of the interior heat. The fan then blows the temperature-controlled air into the vehicle. When heating is required, this process is controlled to transfer a large amount of heat from outside the vehicle to the inside.

[0004] Existing air-conditioning systems in buses require fans to blow temperature-regulated air into the car. On the one hand, the number of fans is limited, and the airflow into the car is uneven, which can easily make passengers feel uncomfortable; on the other hand, the fans themselves require additional electricity.

[0024] The present invention can be implemented in many different forms and should not be considered to be limited to the embodiments described herein. On the contrary, these embodiments are provided to make this disclosure thorough and complete and will fully convey the scope of the invention to those skilled in the art. In the accompanying drawings, components are enlarged for clarity.

[0025] It should be understood that although the terms first, second, third, etc. may be used herein to describe various elements, components, and / or parts, these elements, components, and / or parts are not limited by these terms. These terms are merely used to distinguish elements, components, and / or parts from each other. Therefore, the first element, component, and / or part discussed below can become the second element, component, or part without departing from the teachings of the present invention.

[0026] like Figure 1 As shown, the present invention discloses a bus air conditioning auxiliary system, comprising a first partition, a second partition, M power units, and M air supply modules corresponding one-to-one to the power units, wherein the air supply module comprises N air supply units, where M and N are both natural numbers greater than or equal to 1;

[0027] The first partition and the second partition are arranged in parallel under the roof of the bus to divide the space inside the bus into three cavities: upper, middle and lower. The first partition is arranged above the second partition.

[0028] The front of the bus is evenly provided with M air inlet holes connected to the upper cavity thereof, and the rear of the bus is provided with a plurality of air outlet holes connected to the upper cavity thereof; the M power units are all arranged in the upper cavity inside the bus, corresponding one to one to the M air inlet holes;

[0029] The power unit includes a first bracket, a second bracket, a power rod, N hollow bevel gears and a power impeller, wherein the N hollow bevel gears are evenly arranged on the power rod and coaxially fixedly connected to the power rod, and the N hollow bevel gears have the same orientation, and the N hollow bevel gears correspond one to one to the N air supply units of the corresponding air supply modules of the power unit; the first bracket and the second bracket are fixed to the lower end surface of the bus roof; the two ends of the power rod are respectively connected to the first bracket and the second bracket through bearings, so that the power rod extends parallel to the bus roof along the direction of the bus body and can rotate freely; the power impeller is arranged in the air intake hole corresponding to the power unit, and its rotating shaft is coaxially fixedly connected to the power rod, which is used to drive the power rod to rotate by the incoming air when the bus is running;

[0030] The first partition is provided with M*N mounting holes corresponding one-to-one to the air supply units; the second partition is provided with M*N air supply holes corresponding one-to-one to the air supply units;

[0031] like Figure 2 As shown, the air supply unit includes a driven bevel gear, a transmission rod, an air supply impeller and an impeller cover, wherein the rod body of the transmission rod is connected to the corresponding mounting hole on the first partition through a bearing, the upper end of the transmission rod is coaxially fixedly connected to the rotating shaft of the driven bevel gear, and the lower end is coaxially fixedly connected to the rotating shaft of the air supply impeller; the driven bevel gear is meshed with the hollow bevel gear corresponding to the air supply unit; the impeller cover is a hollow cylinder with an open upper end and a closed lower end, and a plurality of through holes are evenly provided on the lower end surface of the impeller cover, and the upper end of the impeller cover is fixedly connected to the lower end surface of the second partition, so that the impeller cover and the air supply through holes corresponding to the air supply unit are coaxial, as shown Figure 3 As shown; the air supply impeller is arranged in the impeller cover;

[0032] The second partition is also evenly provided with a plurality of ventilation holes.

[0033] The power rod, power impeller, transmission rod and air supply impeller are all made of ABS plastic, so that the moment of inertia is small, which facilitates the start and stop of the power impeller and the air supply impeller.

[0034] When the bus moves forward, the air flows into the air inlet hole, driving the power impeller to rotate and then driving the power rod to rotate. The hollow bevel gear on the power rod transmits the rotation of the power rod to the transmission rod through the driven bevel gear meshing with it, causing the air supply impeller under the transmission rod to rotate. Figure 4 The air supply impeller blows the air in the bus cavity out through the through hole on the lower end surface of the air supply cover, and the bus cavity is replenished with air from the lower cavity through the ventilation through hole on the second partition. Figure 5 shown.

[0035] Since the air supply impellers are evenly distributed on the second partition, the air exchange between the middle cavity and the lower cavity in the bus is even and fine.

[0036] When using this auxiliary air conditioning system, the bus's air conditioning cooling and heating pipes can be placed directly on the second partition. This arrangement eliminates the need for a fan in the bus's air conditioning system. Buses operate almost 24 / 7, generating airflow around the vehicle as they move forward, but this airflow is rarely used. This design utilizes some of the kinetic energy of the external airflow. Through simple mechanical energy transfer, this external wind energy drives the circulation of air inside the vehicle, thereby replacing the fan in the original bus air conditioning system. This reduces vehicle manufacturing costs, minimizes power loss, saves fuel, and reduces exhaust emissions.

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and, unless defined as such, will not be interpreted in an idealized or overly formal sense.
