For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Please refer to Figures 1 to 3The vehicle air conditioning device 100 provided in the embodiment of the present application includes a heat pump device 10, a wheel hub motor 20 and a pneumatic assembly 30. The heat pump device 10 is used to achieve heat transfer. The wheel hub motor 20 can provide power for the vehicle to travel. At the same time, the wheel hub motor 20 can generate heat during operation to provide thermal energy for the vehicle compartment. The pneumatic assembly 30 is used to achieve heat transmission.

[0039] Specifically, the heat pump device 10 is used to provide heating or cooling to the vehicle compartment; it can be understood that the heat pump device 10 is an air compressor, which is similar to the compressor on air-conditioning equipment and refrigeration equipment.

[0040] The wheel hub motor 20 is arranged in the tire of the wheel. Here, the wheel hub motor 20 drives the tire to rotate, thereby providing power for the vehicle to travel. The wheel hub motor 20 includes a shell 21, a motor body 22, a first air pipe 23 and a second air pipe 24. The shell 21 plays a bearing and supporting role, and the shell 21 is connected to the tire of the wheel. The shell 21 has a first cavity 21a and a second cavity 21b that are separated and connected. It can be understood that in space, the first cavity 21a and the second cavity 21b form two independent spaces, however, there is a certain gap between the two, so that the airflow can be connected through the gap. The motor body 22 is arranged in the second cavity 21b, the first cavity 21a is connected to the outside through the first air pipe 23, and the second cavity 21b is connected to the outside through the second air pipe 24. It can be understood that the motor body 22 generates heat during operation, and since the first cavity 21a and the second cavity 21b are connected and relatively independent in space, the heat generated by the motor body 22 can stay in the second cavity 21b for a relatively long time.

[0041] Specifically, the motor body 22 includes a stator and a rotor. The rotor is fixed to the housing 21, and the housing 21 is connected to the tire of the wheel. In this way, as the rotor rotates, the housing 21 can be driven to rotate, and then the tire can be driven to rotate, thereby providing power for the vehicle to travel. The stator of the motor body 22 has an iron core and a coil. When the wheel hub motor 20 is working, the iron core and the coil will generate a lot of heat. It can be understood that the heat generated by the motor body 22 during operation is mainly generated by the iron core and the coil.

[0042] The pneumatic assembly 30 includes a first pipeline 31 having one end connected to the first air pipe 23 and the other end connected to the air port of the heat pump device 10, a second pipeline 32 having one end connected to the second air pipe 24 and the other end connected to another air port of the heat pump device 10, a first pump body 33 connected to the first pipeline 31 and used to pump or exhaust air to the first pipeline 31, and a second pump body 34 connected to the second pipeline 32 and used to pump or exhaust air to the second pipeline 32. It can be understood that the first pump body 33 and the second pump body 34 are used to provide pneumatic power, so that airflow is formed in the first pipeline 31 and the second pipeline 32, and enters and exits the housing 21 through the first air pipe 23 and the second air pipe 24.

[0043] Furthermore, during the process of heating the vehicle compartment, the heating power of the heat pump device 10 is related to the working power of the pump body, that is, the higher the heating temperature in the vehicle compartment, the greater the working power of the pump body.

[0044] For example, when the first air pipe 23 is an air outlet pipe and the second air pipe 24 is an air inlet pipe, the air pumping capacity of the first pump body 33 is related to the heat of heating. The higher the heating temperature in the vehicle compartment, the greater the power of the first pump body 33. Similarly, the air pumping capacity of the second pump body 34 is related to the heating power of the motor body 22. The higher the heating power of the motor body 22, the greater the power of the second pump body 34.

[0045] The vehicle air conditioning device 100 provided in the present application has the following working process: in the heating mode, the heat generated by the motor body 22 of the hub motor 20 fills the entire second cavity 21b, and the first pump body 33 can be selected to evacuate air, and the second pump body 34 can be selected to pump air. At this time, the first air pipe 23 is the air outlet pipe, and the second air pipe 24 is the air inlet pipe. Then, the external air pressure enters the second cavity 21b through the second air pipe 24, and squeezes the hot air in the second cavity 21b into the first cavity 21a. The hot air is then discharged to the first pipeline 31 through the first air pipe 23, and finally through the first pipeline 31. Entering into the heat pump device 10, the heat pump device 10 supplies the heat to the car; or, the first pump body 33 can be selected to pump air, and the second pump body 34 can be selected to extract air. At this time, the first air pipe 23 is the air inlet pipe, and the second air pipe 24 is the air outlet pipe. Then, the external air pressure enters the first cavity 21a through the first air pipe 23, and then enters the second cavity 21b from the first cavity 21a, squeezes the hot air in the second cavity 21b into the second air pipe 24, and discharges it to the second pipeline 32, and finally enters the heat pump device 10 through the second pipeline 32, and the heat pump device 10 supplies the heat to the car. In summary, the vehicle air conditioning equipment 100 of the present application uses the heat generated by the motor body 22 of the hub motor 20 to provide heat energy for the car, thereby reducing the energy consumption of the power supply battery of the electric vehicle.

[0046] Please refer to Figure 3 and Figure 4In one embodiment, the housing 21 is provided with a one-way air hole structure 21c connected to the second cavity 21b, and the one-way air hole structure 21c is used to allow gas to flow from the second cavity 21b to the outside in a one-way manner. It can be understood that the function of the one-way air hole structure 21c is one-way ventilation, that is, the one-way air hole structure 21c achieves one-way ventilation through a structural method. For example, the one-way air hole structure 21c is composed of a through hole and a one-way air-permeable structure arranged outside the through hole. The one-way air-permeable structure is made of a flexible material. The gas is discharged to the outside through the one-way air-permeable structure along the direction from the second cavity 21b to the outside. At this time, the one-way air-permeable structure can expand or expand to meet the ventilation function; and when the gas passes through the one-way air-permeable structure along the direction from the outside to the second cavity 21b, the one-way air-permeable structure is in a deflated or contracted state, and the gas cannot pass through.

[0047] When the air supply of the first pump body 33 and the second pump body 34 is unbalanced, the one-way air hole structure 21c can be used to balance them. For example, when the air pumping volume of the second pump body 34 is greater than the air extraction volume of the first pump body 33, the air pressure in the second cavity 21b is too high, and the extra air can be discharged to the outside through the one-way air hole structure 21c, thereby achieving pneumatic balance.

[0048] Specifically, in one embodiment, there are multiple one-way pore structures 21c, and each one-way pore structure 21c is circumferentially distributed around the central axis of the housing 21. It can be understood that the housing 21 of the hub motor 20 rotates with the wheel, and the one-way pore structure 21c thereon also rotates with the housing 21, and the second cavity 21b is connected to the outside during the rotation.

[0049] Preferably, each unidirectional air hole structure 21c can form a dynamic correspondence with the stator of the motor body 22, that is, during the rotation of the outer shell 21, the circular trajectory of each unidirectional air hole structure 21c coincides or basically coincides with the circular trajectory enclosed by the stator of the motor body 22. In this way, when the pumping volume of the second pump body 34 is greater than the suction volume of the first pump body 33, the excess hot air can be discharged from the second cavity 21b to the outside more quickly.

[0050] Specifically, in one embodiment, the wheel hub motor 20 further includes a one-way air valve, and the one-way air hole structure 21c allows gas to flow from the second cavity 21b to the outside in one direction through the one-way air valve. It can be understood that the one-way air valve has one-way air permeability, and the one-way air valve can be a commercially available product, that is, it is arranged outside the housing 21 and communicated with the one-way air hole structure 21c.

[0051] The one-way valve can limit the gas to flow only from the second cavity 21b to the outside. Usually, the one-way valve is in a normally closed state, and the one-way valve can be in an open state only when the gas pressure reaches a certain range.

[0052] In one embodiment, the activation threshold of the one-way air valve can be set according to actual use requirements, that is, the one-way air valve has a ventilation threshold, and when the air pressure in the second cavity 21b is greater than the ventilation threshold, the one-way air valve is connected to the outside. It can be understood that once the air pressure in the second cavity 21b is greater than the ventilation threshold, the one-way air valve is in an open state and is connected to the external air.

[0053] For example, when the air extraction volume of the first pump body 33 is less than the air pumping volume of the second pump body 34, the air pressure in the second cavity 21b increases. Therefore, in order to maintain the upper limit air pressure in the second cavity 21b in a certain steady state, as long as the air pressure in the second cavity 21b is greater than the ventilation threshold of the one-way air valve, the one-way air valve is in an open state, so that the second cavity 21b is depressurized; at the same time, excess hot air can also be discharged from the second cavity 21b to the outside to dissipate heat, thereby avoiding damage to the motor body 22 due to untimely heat dissipation, thereby reducing the life of the hub motor 20.

[0054] Please refer to Figure 1 and Figure 2 When the air pressure in the first cavity 21a and the second cavity 21b is unbalanced, in addition to the pressure relief method in the above-mentioned embodiment, the pressure can also be increased. In one embodiment, the second pump body 34 is provided with an air inlet (not shown in the figure), and the external gas enters the second pump body 34 through the air inlet and flows into the second pipeline 32. It can be understood that when the flow rates of the first pump body 33 and the second pump body 34 are different, especially when the pumping volume of the second pump body 34 is less than the suction volume of the first pump body 33, the air pressure that needs to be supplemented can enter the second pipeline 32 through the air inlet on the second pump body 34 to supplement the second cavity 21b. Please refer to Figure 1 and Figure 2 In one embodiment, the pneumatic assembly 30 further includes a valve body 35, which is used to open and close the first pipeline 31; wherein, in the heating state, the valve body 35 is in a passage state. It can be understood that the first cavity 21a is connected to an air port of the heat pump device 10 through the first air pipe 23 and the first pipeline 31, and the second cavity 21b is connected to another air port of the heat pump device 10 through the second air pipe 24 and the second pipeline 32, thereby forming a heat supply and demand cycle, that is, the heat generated by the motor body 22 of the hub motor 20 is transmitted to the heat pump device 10, and the heat pump device 10 performs heat exchange to supply heat energy to the vehicle compartment, and the cold air formed in the process can also be transmitted back to the housing 21 of the hub motor 20 to cool the motor body 22.

[0055] Please refer to Figure 2 and Figure 3In one embodiment, in the cooling state, the valve body 35 is in a closed state. It can be understood that in the cooling process, the first pump body 33 and the second pump body 34 are both in the pumping state. At this time, the first air pipe 23 and the second air pipe 24 are both air inlet pipes, and the hot air generated in the condensation process of the heat pump device 10 can be discharged to the outside through the one-way air hole structure 21c. Since the one-way air hole structure 21c is connected to the second cavity 21b, the hot air generated in the condensation process of the heat pump device 10 can be directly released to the outside through the one-way air hole structure 21c after being transferred into the second cavity 21b via the second pipeline 32. In this way, the heat generated by the vehicle air conditioning equipment 100 in the cooling process can be quickly dissipated. Therefore, the valve body 35 should be in a closed state to block the first pipeline 31, so as to prevent the hot air generated by the heat pump device 10 during the refrigeration process from entering the first cavity 21a through the first pipeline 31 and causing stagnation. The second pump body 34 pumps the gas in the second pipeline 32 into the second cavity 21b of the outer shell 21, and discharges it to the outside through the one-way air hole structure 21c.

[0056] Since the vehicle air conditioning equipment 100 is in the cooling state, the heat pump device 10 pumps hot air into the housing 21 of the hub motor 20 through the second pipeline 32. In order to prevent the motor body 22 disposed in the housing 21 from being damaged due to excessive heat, at this time, cold air needs to be simultaneously input into the housing 21 to cool the motor body 22. Specifically, an air inlet (not shown in the figure) can be provided on the second pump body 34, and external air enters the second pump body 34 through the air inlet and flows into the second pipeline 32. At this time, the gas in the second pipeline 32 is the hot air generated by the heat pump device 10 during the cooling process and the cold air flowing in through the air inlet. The second pump body 34 pumps the gas in the second pipeline 32 into the housing 21 to complete the processing of the heat generated by the heat pump device 10 during the cooling process and the heat generated by the motor body 22 during operation.

[0057] Alternatively, an air inlet (not shown in the figure) may be provided on the first pump body 33, and external air enters the first pump body 33 through the air inlet and flows into the first pipeline 31, and the first pump body 33 pumps the gas in the first pipeline 31 into the outer shell 21 to complete the treatment of heat generation of the heat pump device 10 during the refrigeration process and heat generation of the motor body 22 during operation; of course, when excessive heat generation occurs, an air inlet (not shown in the figure) may be provided on the first pump body 33 and the second pump body 34 at the same time, and external air enters the first pump body 33 and the second pump body 34 through the air inlet and flows into the first pipeline 31 and the second pipeline 32, and the first pump body 33 and the second pump body 34 pump the gas in the first pipeline 31 and the second pipeline 32 into the outer shell 21, thereby enhancing the heat dissipation effect, and the air pressure formed in the outer shell 21 can be balanced with the outside through the one-way pore structure 21c.

[0058] Please refer to Figure 1 and Figure 2In one embodiment, the heat pump device 10 includes a first condenser 11 and a second condenser 12 that are connected to each other. The first condenser 11 is used to connect the first air pipe 23 and the second air pipe 24, and the second condenser 12 is connected to the vehicle compartment. It can be understood that during the heating process, the first condenser 11 absorbs heat, while the second condenser 12 dissipates heat, and the generated heat energy is supplied to the vehicle compartment, while during the cooling process, the first condenser 11 dissipates heat, and the second condenser 12 absorbs heat, and supplies cold air to the vehicle compartment.

[0059] The embodiment of the present application also provides a vehicle, comprising the above-mentioned vehicle air conditioning device 100.

[0060] The vehicle has a plurality of wheel hub motors 20 provided in the above embodiments, the wheel hub motors 20 are arranged on the tires, and the vehicle is driven by the wheel hub motors 20. For example, the vehicle can be driven by two wheel hub motors 20 or four wheel hub motors 20, and accordingly, two or four groups of the above pneumatic components 30 can be arranged according to the number of wheel hub motors 20 of the vehicle. Each group of pneumatic components 30 can be controlled independently, and since the operating state of each wheel hub motor 20 is not exactly the same, independent control can more flexibly adjust the temperature of the vehicle air conditioning device 100.

[0061] The vehicle provided in the present application, on the basis of having the above-mentioned vehicle air conditioning equipment 100, has lower battery power consumption and can increase the cruising range.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
