Description

Technical Field

[0001] This invention relates to a dual-power compressor and an automotive air conditioning system incorporating the same. Background Technology

[0002] Dual-power automotive air conditioning compressors are powered by both the car's engine and the vehicle's 24V battery. Currently available dual-power compressors fall into two categories: one with a dual-scroll structure, where two scrolls compress air separately from the engine and battery, sharing a common intake and exhaust chamber. A drawback is that when the two power sources operate independently, air can easily flow between the intake and exhaust chambers, leading to a higher failure rate. The other type is based on a gearbox, where both the engine and battery are connected to a gearbox, which then transmits power to the scrolls to compress air. The disadvantage of this type is that the two power sources cannot operate independently; when the engine drives the gearbox, the battery-driven motor also needs to run, and vice versa, resulting in higher power consumption. Furthermore, regardless of the operating method, the transmission from the gearbox to the scrolls involves energy loss, leading to low operating efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of existing systems. This invention provides a dual-power compressor and an automotive air conditioning system including the compressor.

[0004] This invention is achieved through the following technical solution:

[0005] A dual-power compressor includes an engine drive assembly, a battery drive assembly, a transmission device, a one-way bearing, a scroll compressor mechanism, and a main shaft. One end of the main shaft is directly connected to the scroll compressor mechanism, and the other end of the main shaft is connected to the one-way bearing. Both ends of the transmission device are respectively connected to the one-way bearing and the engine drive assembly, so that the engine drive assembly drives the rotation of the transmission device and transmits the rotation to the main shaft and the scroll compressor mechanism through the one-way bearing. The battery drive assembly includes a stator and a rotor located within the stator. The rotor is sleeved and connected to the main shaft, so that the battery drive assembly drives the rotation of the rotor, the main shaft, and the scroll compressor mechanism, and transmits the rotation to the transmission device through the one-way bearing.

[0006] Furthermore, the transmission device is a speed increaser.

[0007] Furthermore, the speed increaser includes a sun gear, planet gears, and an internal gear ring. The sun gear and the planet gears are both located inside the internal gear ring, and the two ends of the planet gears are respectively engaged with the inner wall surfaces of the sun gear and the internal gear ring. The sun gear is connected to the one-way bearing, and the planet gears are connected to the engine drive assembly.

[0008] Furthermore, the inner ring of the one-way bearing is fitted onto and connected to the main shaft, and the outer ring of the one-way bearing is connected to the sun gear.

[0009] Furthermore, the scroll compression mechanism includes a stationary scroll disk and a moving scroll disk that cooperate with each other, with the moving scroll disk being directly connected to the main shaft.

[0010] Furthermore, the engine drive assembly includes a clutch assembly, an engine body, and a belt, with both ends of the belt fitted onto the output ends of the clutch assembly and the engine body, and the transmission device connected to the clutch assembly.

[0011] Furthermore, the dual-power compressor also includes a clutch detection component and a control device. The clutch detection component is connected to the clutch assembly and is used to detect the engagement or disengagement of the clutch assembly. The input terminal of the control device is electrically connected to the clutch detection component and is electrically connected to the battery drive assembly and is used to control the opening and closing of the battery drive assembly.

[0012] An automotive air conditioning system comprising a dual-power compressor as described above.

[0013] The beneficial effects of this invention are as follows:

[0014] The present invention relates to a dual-power compressor and an automotive air conditioning system comprising the same. The power source provided by the engine drive assembly is transmitted to the scroll compressor mechanism via a transmission device, a one-way bearing, and a main shaft. The power source provided by the battery drive assembly is transmitted to the scroll compressor mechanism via the main shaft. The one-way bearing enables the main shaft to be disengaged from the transmission device. The two power sources operate independently without interference and can be freely switched, thus achieving independent operation under each power source. Simultaneously, when the battery drive assembly generates power, it directly drives the scroll compressor mechanism, thereby reducing power consumption and achieving high efficiency and energy saving.

[0044] The following description of the embodiments is taken with reference to the accompanying drawings, which illustrate specific embodiments in which the invention can be implemented.

[0045] This embodiment discloses a dual-power compressor, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the dual-power compressor includes an engine drive assembly 1, a battery drive assembly 2, a main shaft 3, a scroll compressor mechanism 4, a one-way bearing 5, and a transmission device 6. One end of the main shaft 3 is directly connected to the scroll compressor mechanism 4, and the other end of the main shaft 3 is connected to the one-way bearing 5. Both ends of the transmission device 6 are connected to the one-way bearing 5 and the engine drive assembly 1, respectively, so that the engine drive assembly 1 drives the rotation of the transmission device 6 and transmits the rotation to the main shaft 3 and the scroll compressor mechanism 4 through the one-way bearing 5. The battery drive assembly 2 includes a stator 21 and a rotor 22 located in the stator 21. The rotor 22 is sleeved and connected to the main shaft 3, so that the battery drive assembly 2 drives the rotation of the rotor 22, the main shaft 3, and the scroll compressor mechanism 4 and transmits the rotation to the transmission device 6 through the one-way bearing 5.

[0046] The dual-power compressor of this embodiment is applied in an automobile. When the vehicle is driving or idling, the compressor uses the engine as its power source, with energy derived from the fuel. The mechanical drive component provides power, meaning the engine drive assembly 1 operates and provides power, while the battery drive assembly 2 does not operate and provide power, thus eliminating the need for the battery drive assembly 2 to consume electricity. The power source provided by the engine drive assembly 1 is transmitted sequentially through the transmission device 6, the one-way bearing 5, and the main shaft 3 to the scroll compressor mechanism 4, which compresses air to achieve the operation of the dual-power compressor. When the vehicle is parked, the compressor uses the battery as its power source, with energy derived from the battery. The pure electric drive component provides power, meaning the battery drive assembly 2 operates and provides power, thus eliminating the need for the engine drive assembly 1 to operate and provide power. The power source provided by the battery drive assembly 2 is transmitted through the main shaft 3 to the scroll compressor mechanism 4, which compresses air to achieve the operation of the dual-power compressor. By placing the one-way bearing 5 between the transmission device 6 and the main shaft 3, the battery drive assembly 2 can disengage the main shaft 3 from the transmission device 6 during operation via the one-way bearing 5. This allows the two power sources to operate independently without interference and can be switched freely. Furthermore, placing the transmission device 6 between the main shaft 3 and the engine drive assembly 1, rather than between the main shaft 3 and the scroll compressor mechanism 4, allows the battery drive assembly 2 to directly drive the scroll compressor mechanism 4 when generating power, thereby reducing power consumption and achieving high efficiency and energy saving.

[0047] In this embodiment, the transmission device 6 is a speed increaser. Because the output speeds of the engine drive assembly 1 and the battery drive assembly 2 differ—the engine drive assembly 1 requires a higher speed, while the battery drive assembly 2 requires a lower speed—the same set of scroll compressor mechanisms 4 cannot achieve the desired result. Therefore, a speed increaser is needed to amplify the speed when the engine drive assembly 1 generates power. When the battery drive assembly 2 drives the motor, power consumption needs to be reduced. This can be achieved by disengaging the speed increaser from the pulley via a one-way bearing 5. Thus, a one-way bearing 5 with a clutch function is required for disengagement, allowing independent operation under the two power sources. Simultaneously, the speed increaser increases the compressor speed under the engine drive assembly 1 power source, and the one-way bearing 5 allows disengagement of the speed increaser from the pulley at the engine end under the battery drive assembly 2 power source, enabling free switching between the two power sources.

[0048] The speed increaser includes a sun gear 61, planet gears 62, and an internal gear ring 63. Both the sun gear 61 and planet gears 62 are located within the internal gear ring 63, and the two ends of the planet gears 62 mesh with the inner walls of the sun gear 61 and the internal gear ring 63, respectively. The sun gear 61 is connected to a one-way bearing 5, and the planet gears 62 are connected to the engine drive assembly 1. Specifically, in this embodiment, the sun gear 61 includes a sun gear body 611, a sun gear holder 612, and a sun gear bearing 613. The one-way bearing 5 is connected within the sun gear body 611, and the sun gear bearing 613 is sleeved on the sun gear body 611 and located between the sun gear body 611 and the sun gear holder 612. The planet gears 62 include a planet carrier 622 and multiple planet gear bodies 621. The planet carrier 622 is connected to the multiple planet gear bodies 621, and the multiple planet gear bodies 621 mesh with the inner walls of the sun gear body 611 and the internal gear ring 63. It achieves high transmission efficiency and high stability, and has a compact overall structure that is easy to install and connect.

[0049] In this design, the inner ring of the one-way bearing 5 is fitted and connected to the main shaft 3, while the outer ring of the one-way bearing 5 is connected to the sun gear 61. The rotation of the sun gear 61 drives both the outer and inner rings of the one-way bearing 5 to rotate, thus driving the rotation of the main shaft 3. The rotation of the main shaft 3 drives the inner ring of the one-way bearing 5 to rotate, but not the outer ring. This ensures that the battery drive assembly 2 does not drive the speed increaser and pulley during operation, thereby reducing power consumption and achieving high energy efficiency.

[0050] In this embodiment, the scroll compression mechanism 4 includes a stationary scroll disk 41 and a moving scroll disk 42 that cooperate with each other. The moving scroll disk 42 is directly connected to the main shaft 3. When the battery drive assembly 2 is running, the rotation of the rotor 22, via the stator 21 and rotor 22, drives the main shaft 3 to rotate. The main shaft 3 directly drives the moving scroll disk 42 to cooperate with the stationary scroll disk 41 to compress air, reducing power consumption and achieving high efficiency and energy saving. The battery drive assembly 2 also includes a vehicle battery 23, which provides power to enable the rotation of the rotor 22.

[0051] Both the engine drive assembly 1 and the battery drive assembly 2 are directly connected to a set of scroll compressor mechanisms 4 via the main shaft 3 for compression output. The power source provided by the engine drive assembly 1 is transmitted to the scroll compressor mechanism 4 through the transmission device 6, while the power source provided by the battery drive assembly 2 is transmitted to the scroll compressor mechanism 4 through the rotor 22 and the main shaft 3. The two power sources operate independently, mainly separated by a one-way bearing 5 to switch between them, and finally compressed and output by the same scroll compressor mechanism 4. In this embodiment, the dual-power compressor is designed as a set of scroll compressor mechanisms 4, which solves both the problem of air leakage between the intake and exhaust chambers and the problem of high power consumption.

[0052] In this embodiment, the engine drive assembly 1 includes an engine body 11, a belt 12, and a clutch assembly 13. Both ends of the belt 12 are fitted onto the output ends of the clutch assembly 13 and the engine body 11. A transmission device 6 is connected to the clutch assembly 13. The output ends of the engine body 11 and the outer surfaces of the clutch assembly 13 have pulleys. Both ends of the belt 12 are fitted onto the pulleys of the engine body 11 and the clutch assembly 13. When the engine drive assembly 1 is running, the engine body 11 provides power, which is transmitted to the clutch assembly 13 via the belt 12. The clutch assembly 13 is in an engaged state and transmits power to the transmission device 6, then sequentially through the one-way bearing 5 and the main shaft 3, and finally to the scroll compressor mechanism 4. When the vehicle is stopped, the engine body 11 no longer provides power, and the clutch assembly 13 is in a disengaged state.

[0053] The dual-power compressor also includes a control device 7 and a clutch detection component 8. The clutch detection component 8 is connected to the clutch assembly 13 and is used to detect the engagement or disengagement of the clutch assembly 13. The input terminal of the control device 7 is electrically connected to the clutch detection component 8 and the battery drive assembly 2, and is used to control the opening and closing of the battery drive assembly 2. The control device 7 is responsible for receiving commands from the air conditioning panel. When the dual-power compressor needs to be started, if the clutch detection component 8 detects that the clutch assembly 13 is engaged, it indicates that the engine drive assembly 1 is running. The vehicle is powered by the engine drive assembly 1 during driving or idling, without the need for the battery drive assembly 2. If the clutch detection component 8 detects that the clutch assembly 13 is disengaged, it indicates that the engine drive assembly 1 is not running, the vehicle is stationary, and the control device 7 provides power by controlling the battery drive assembly 2. The control device 7 can also be used to receive engine speed commands from the vehicle's VCU and feed them back to the air conditioning panel, and to determine whether the mechanical clutch assembly 13 is engaged or disengaged.

[0054] This embodiment also discloses an automotive air conditioning system, which includes a dual-power compressor as described above.

Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
