Description

TECHNICAL FIELD

[0002] A vehicle-mounted air conditioner is composed of a compressor, a condenser, a throttling element, an evaporator, a fan and necessary control components, and is used for adjusting the temperature and humidity in a vehicle to provide a comfortable environment for passengers. With the development of electric vehicles and hybrid electric vehicles, the endurance of the battery is crucial, and the vehicle-mounted air conditioner consumes part of the electric quantity. The existing vehicle-mounted power generation mode has certain insufficient utilization, resulting in very small wind energy that is actually converted. Moreover, although some achieve power generation, the effect of the air conditioner of the vehicle itself is affected.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0037] An automobile air conditioner power generation device, as shown in Figure 1 includes a wind guide pipe 1, a longitudinal axis 2 and a transverse axis 3, and a transmission assembly. A plurality of longitudinal axes 2 are parallel to each other and are rotatably installed in the wind guide pipe 1. A plurality of transverse axes 3 are parallel to each other and are rotatably installed in the wind guide pipe 1. In addition, the longitudinal axis 2 is located on one side of the transverse axis 3, the longitudinal axis 2 and the transverse axis 3 do not intersect, and the longitudinal axis 2 and the transverse axis 3 are perpendicular. In addition, the longitudinal axis 2 and the transverse axis 3 are both provided with fan blades 11 on the surface. One end of the longitudinal axis 2 is connected with a generator 8, one end of the transverse axis 3 is connected with the transmission assembly, the transmission assembly is drivingly connected with a conveying shaft 7, and the conveying shaft 7 is connected with the generator 8.​

[0038] It should be noted that the number of vertical axes 2 and horizontal axes 3 is related to the internal size of the air duct 1; in some cases, even only one axis is used. Figure 1 In this structure, there are two vertical shafts 2 and two horizontal shafts 3, forming a grid-like structure. Bearings are required at the contact points between the vertical shafts 2 and 3 and the air guide duct 1 to ensure stable rotation of the shafts 2 and 3. Additionally, the conveyor shaft 7 also requires a corresponding support structure to ensure stable rotation. Figure 1 In the middle, the transmission components are located on both sides of the air duct 1, and in addition... Figure 1 The cross-section of the central air duct 1 is rectangular. However, its shape is not fixed during implementation and can be designed as a circle or other shapes.

[0039] It should be noted that the energy transmitted when the fan blades 11 rotate in the transmission assembly is generally transmitted using gear transmission. Specifically, the transmission assembly is located outside the air guide duct 1 and includes a first gear 4, a second gear 5, and a third gear 6, all of which are bevel gears. The end face of the first gear 4 is fixedly connected to the horizontal shaft 3, and the end face of the third gear 6 is fixedly connected to the conveyor shaft 7. Both the first gear 4 and the third gear 6 mesh with the second gear 5. When the fan blades 11 rotate under the action of wind, they drive the longitudinal shaft 2 and the horizontal shaft 3 to rotate coaxially. The longitudinal shaft 2 then directly transmits mechanical energy to the generator 8, which generates electricity. Simultaneously, the horizontal shaft 3 drives the first gear 4 to rotate, which in turn drives the second gear 5 to rotate. The second gear 5 then drives the conveyor shaft 7 to rotate, which in turn transmits mechanical energy back to the generator 8. Additionally, the second gear 5 is rotatably connected to a support (not shown in the figure) to support the entire transmission assembly.

[0040] It should be further explained that the conveyor shaft 7 and the longitudinal shaft 2 are connected to the rotor of the generator 8, which then drives the rotor to rotate, cutting the magnetic field of the stator and generating voltage. The voltage generated by the generator 8 needs to be transformed through a transformer (not shown in the figure) to convert it into the voltage value for vehicle power consumption.

[0041] In addition, in practical applications, the transmission ratio of the first gear 4, the second gear 5, and the third gear 6 can be adjusted as needed. For example, if it is necessary to increase the speed of the third gear 6, the number of teeth of the first gear 4 or the second gear 5 can be increased. Conversely, if it is necessary to decrease the speed of the third gear 6, the number of teeth of the first gear 4 or the second gear 5 can be decreased.

[0042] In addition, the present application has other embodiments, for example, the gear transmission structure can be abandoned, and a generator 8 is added, so that the longitudinal shaft 2 and the transverse shaft 3 can be connected with the generator 8, and the energy loss in the gear transmission is reduced.

[0043] Further, the generator 8 is located outside the air duct 1.

[0044] It should be noted that the generator 8 is generally located near the air duct 1, so as to be connected with the longitudinal shaft 2 in the air duct 1. In addition, the air conditioner air in the air duct 1 can have a temperature difference with the air conditioner air outside the air duct 1, so that condensate water can be generated at the connection between the longitudinal shaft 2 and the air duct 1. Therefore, when the longitudinal shaft 2 passes through the air duct 1, bolts, gaskets, raw belts and the like are used for sealing.

[0045] Further, the generator 8 is provided with a cooling fin 9.

[0046] It should be noted that the cooling fin 9 helps the generator 8 to dissipate heat; in addition, the cooling fin 9 can be replaced by other heat dissipation methods, for example, air cooling or water cooling.

[0047] Further, as shown in Figure 2 , one end of the air duct 1 is provided with an air outlet 101, and the other end is provided with a blower 14, and then the blower 14 is connected with an air compressor 12, and the generator 8 is further connected with a power transmission line 10, and the power transmission line 10 is connected with a storage battery 13, and in addition, the storage battery 13 is electrically connected with the air compressor 12 and the blower 14; and the automobile air conditioner power generation device further comprises a controller 17, and the controller 17 is electrically connected with the generator 8, the air compressor 12, the storage battery 13 and the blower 14.

[0048] It should be noted that when the air conditioner switch in the vehicle is turned on for the first time, the air compressor 12 starts to work, drives the blower 14 to blow out the air conditioner air along the air duct 1, and then transmits power to the generator 8 through the transmission assembly to generate power. The power is transmitted to the storage battery 13 through the power transmission line 10 for storage. At the same time, when the controller 17 detects that the storage battery 13 meets the input voltage, the storage battery 13 is started to supply power, and at this time, the vehicle power supply mode is cut off.

[0049] In addition, the power generation system is arranged in the air conditioner pipeline of the whole vehicle, so that as soon as the air conditioner starts, the vehicle self-power supply starts, and the consumption of the vehicle endurance power and fuel consumption is reduced.

[0050] When the air conditioning is turned off, the air compressor 12 stops working, the blower 14 stops blowing air, and no air conditioning air blows out of the air duct 1. Therefore, the transmission components and generator 8 also stop working, and there is no new power input to the battery 13. At the same time, the controller 17 detects the stop signal and cuts off the power supply. When the air conditioning is turned on again, the controller 17 can prioritize starting the battery 13 to supply power to the blower 14 and air compressor 12, achieving normal air supply, thereby driving the fan blades 11 to rotate and charge the battery 13.

[0051] It should be noted that, as a control system, controller 17 needs to be installed in a manually operable location, typically using buttons or a touchscreen for manual control. Furthermore, controller 17 needs to be installed in an easily accessible location. Figure 4 Installing the controller 17 on one side of the air compressor 12 is just one installation method. It can also be installed in other locations, depending on the usage requirements. For example, it can be set in the center console of a car, as long as it is convenient for the user to adjust it through the controller 17.

[0052] Furthermore, the fan blade 11 has shapes including semi-circular and rectangular. Figure 1 The middle fan blade 11 is semi-circular.

[0053] Of course, the shape of the fan blade 11 is not limited to semi-circle and rectangle; the specific shape depends on the actual needs.

[0054] It should be noted that the airflow in duct 1 is sometimes uncontrollable, while Figure 1 The middle fan blade 11 has a symmetrical structure. When the symmetrical fan blades 11 are all on the windward side and bear the same wind force, the rotation of the fan blades 11 will be disturbed. Therefore, a converging structure is added to the air guide duct 1. The following structure is provided as an example of a "well" shape formed by two longitudinal axes 2 and two transverse axes 3:

[0055] Install in air duct 1 Figure 3 The system includes a frame 16 and a converging tube 15. The frame 16 has mounting holes 1601 for bolt connection to the air duct 1, and sealing rings are installed at the connection points. The converging tube 15 is a trapezoidal structure with a gradually decreasing opening, and the end with the smaller opening can be positioned in the middle of the "well" shaped structure. When the air conditioning air passes through the converging tube 15, the airflow will blow the four fan blades 11 in the middle of the "well" shape. The rotation of the four fan blades 11 will not interfere with each other, and the airflow will be converted into mechanical energy and transmitted.

[0056] It should be noted that, Figure 3 The middle frame 16 is rectangular in shape to correspond with the air duct 1. If the air duct 1 adopts a different shape, the frame 16 needs to be consistent with the shape of the air duct 1.

[0057] The operation of the automotive air conditioning power generation device of the present invention will be described below in conjunction with the convergence structure, wherein there are two longitudinal axes 2 and two transverse axes 3:

[0058] First, turn on the air conditioner. Then, turn on the air compressor 12 and blower 14 via controller 17. Blower 14 blows the air conditioner air into the air duct 1. After passing through the converging structure, the air conditioner air is concentrated vertically towards the middle of the "well" shaped structure. Then, the four fan blades 11 rotate, simultaneously driving the longitudinal shaft 2 and the transverse shaft 3 to rotate. The longitudinal shaft 2 then transmits power to the generator 8. The transverse shaft 3 first transmits power to the first gear 4. Then, the first gear 4 causes the second gear 5 to rotate. The second gear 5 then causes the third gear 6 to rotate. The power is then transmitted to the conveyor shaft 7 via the third gear 6, and then to the generator 8 via the conveyor shaft 7. Finally, the generator 8 converts the mechanical energy into electrical energy and stores it in the battery 13.

[0059] It should be noted that, Figure 4 The convergence structure in the text is only the corresponding Figure 1 One embodiment of the structure is that the convergence structure is installed on one side of the fan blade 11. If the number or position of the longitudinal axis 2, the transverse axis 3 and the fan blade 11 changes, the convergence structure also needs to be modified.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
