[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art may adjust them as needed to suit specific applications.

[0039] Secondly, it should be noted that in the description of this application, terms such as "front", "back", "left", "right", "up", "down", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0040] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0042] The use of new energy vehicles is becoming more and more widespread. New energy vehicles include many different types such as pure electric vehicles and hybrid vehicles. All types of new energy vehicles need to be equipped with compressors to achieve the function of cooling the interior of the vehicle. The compressor of a hybrid vehicle is usually an electric compressor, which is driven by electricity and is relatively independent of the power system of the hybrid vehicle, thereby ensuring that the cooling function can be achieved by the electric compressor in both fuel-driven and electric-driven driving modes, as well as in parking or driving states.

[0043] However, the cost of electric compressors adapted for hybrid systems is currently high. At the same time, the control of electric compressors is complex, the manufacturing of chips and control modules is easily restricted by the environment, and most of the internal components of electric compressors are high-voltage devices, which require high safety technology. In addition, electric compressors are easily damaged by high-voltage circuits and have a high failure rate. The control module of the electric compressor requires refrigerant for cooling due to electrical heating, which consumes a lot of energy.

[0044] In response to the above problems, the embodiments of the present application provide a hybrid power system and a vehicle. By integrating a mechanical compressor therein and coordinating the mechanical compressor with a gearbox, when applied to a hybrid vehicle, the hybrid power system can be used to drive the mechanical compressor to work under different working conditions, such as parking, driving, etc., and in different working modes, such as engine drive mode or pure electric mode. Therefore, while ensuring that the compressor can be started to achieve cooling in different working modes and operating states of the hybrid vehicle, the cost of the compressor is reduced. In addition, there is no need for a complex control system, the manufacturing cost is low, and it will not be affected by the high-voltage circuit. Moreover, since there is no separate control module, no refrigerant is required for cooling, which reduces energy consumption.

[0045] Figure 1 A schematic diagram of the structure of a hybrid power system provided in an embodiment of the present application is shown in FIG. Figure 2 This is a schematic diagram of the cooperation between the drive shaft and the transmission shaft when the second clutch is disengaged in the hybrid system provided by an embodiment of the present application. Figure 3 This is a schematic diagram of a first state of cooperation between the drive shaft and the transmission shaft when the second clutch is connected in the hybrid system provided by an embodiment of the present application. Figure 4 This is a schematic diagram of a second state of cooperation between the drive shaft and the transmission shaft when the second clutch is connected in the hybrid system provided by an embodiment of the present application. Figure 5 Another structural schematic diagram of the hybrid power system provided in an embodiment of the present application.

[0046] like Figures 1 to 5 As shown, an embodiment of the present application provides a hybrid power system, which can be applied to a hybrid vehicle. The hybrid power system includes an engine 100, a motor 200, a mechanical compressor 300 and a transmission assembly 400. On the one hand, through the cooperation of the engine 100, the motor 200 and the transmission assembly 400, the hybrid power system can drive the vehicle to operate, and has two different driving sources, the engine 100 and the motor 200, thereby realizing different driving modes such as fuel drive and electric drive. On the other hand, the mechanical compressor 300 is integrated in the hybrid power system, and any one of the engine 100 and the motor 200 is used to drive the operation of the mechanical compressor 300 through the transmission assembly 400, thereby realizing the function of air conditioning and refrigeration in the vehicle.

[0047] Among them, the transmission assembly 400 includes a gearbox 410 and a first clutch 420. The first clutch 420 is connected between the engine 100 and the gearbox 410, and the engine 100 is connected to the first side of the first clutch 420, and the gearbox 410 is connected to the second side of the first clutch 420. The transmission or disconnection between the engine 100 and the gearbox 410 is achieved through the engagement or disengagement of the first clutch 420. That is, when the first clutch 420 is connected, the power output by the engine 100 can be transmitted to the gearbox 410, and when the first clutch 420 is disengaged, it can be driven by the engine 100 and converted to be driven by the motor 200.

[0048] In some embodiments, the gearbox 410 may include a second clutch 414, a transmission shaft 413 and at least one drive shaft, the drive shaft being used to connect to the second side of the first clutch 420, and the motor 200 and the mechanical compressor 300 are both connected to the drive shaft, and the second clutch 414 is arranged between the transmission shaft 413 and the drive shaft to control the connection or separation of the transmission shaft 413 and the drive shaft.

[0049] It can be understood that by controlling the second clutch 414, the power of the engine 100 or the motor 200 can be transmitted to the drive shaft 413. The drive shaft 413 serves as a component for outputting power from the gearbox 410. When the hybrid power system is applied to a car, it can drive the car to run. In addition, the drive shaft can transmit the power of the engine 100 or the motor 200 to the mechanical compressor 300 to achieve cooling.

[0050] It should be noted that in the hybrid system provided in the embodiment of the present application, the mechanical compressor 300 is coordinated with the gearbox 410, so that when applied to a vehicle, the mechanical compressor 300 can be driven to work in both the engine 100 drive mode and the pure electric mode. Therefore, while ensuring that the compressor can be started to achieve cooling in different working modes and operating states of the hybrid vehicle, the cost of the compressor is reduced.

[0051] In addition, the mechanical compressor 300 provided in the embodiment of the present application can be a fixed-displacement compressor, an internally controlled displacement compressor, an externally controlled displacement compressor, etc. The present application does not specifically limit its specific displacement type, and the specific working principle of the mechanical compressor 300 for realizing the refrigeration function is the existing technology and will not be elaborated here.

[0052] In possible implementations, the gearbox 410 may be of various types. Each type of gearbox 410 may have a different number of drive shafts and different ways of coordinating the drive shafts with the transmission shaft 413. For example, the gearbox 410 may be a dual-drive shaft gearbox, a continuously variable transmission (CVT), an automatic transmission (AT), etc. A dual-drive shaft gearbox is used as an example for detailed description.

[0053] Please continue to refer to Figures 1 to 4 As an optional embodiment, the drive shaft may include a first drive shaft 411 and a second drive shaft 412, both of which can be connected to the second side of the first clutch 420, the motor 200 is connected to either the first drive shaft 411 or the second drive shaft 412, and the mechanical compressor 300 is connected to either the first drive shaft 411 or the second drive shaft 412.

[0054] It is understandable that the second clutch 414 can control the cooperation between the first drive shaft 411 and the second drive shaft 412 and the transmission shaft 413, so that through the control of the second clutch 414, reliable operation of the mechanical compressor 300 in different driving modes can be achieved.

[0055] In some embodiments, the transmission shaft 413 can be disposed to the sides of the first drive shaft 411 and the second drive shaft 412. The second clutch 414 can control whether the first drive shaft 411 or the second drive shaft 412 is connected to or disconnected from the drive shaft. Furthermore, the first drive shaft 411 and the second drive shaft 412 can be disposed in parallel, thereby facilitating the installation of the second clutch 414, ensuring a rational design of the space within the transmission case 410 and improving space utilization.

[0056] It is understandable that in order to ensure that the mechanical compressor 300 can be driven in different modes, the motor 200 and the mechanical compressor 300 can be connected to the same drive shaft.

[0057] For example, the motor 200 and the mechanical compressor 300 can both be connected to the first drive shaft 411, or the motor 200 and the mechanical compressor 300 can both be connected to the second drive shaft 412. This arrangement ensures the convenience of switching between different modes and allows different coordination methods to be adopted according to different situations when designing the internal space of the gearbox 410.

[0058] It should be noted that when the hybrid system is applied to a car, the car can have different states such as parking and driving, and each state can have a power mode driven by the engine 100 and a pure electric mode driven by the motor 200. The different states and different modes are explained below.

[0059] Please continue to refer to Figures 1 to 4 , when the car is in park:

[0060] First, the engine 100 is in the starting state, which is the power mode. If the air conditioner in the car is turned on, the first clutch 420 is engaged and the second clutch 414 is disengaged. At this time, the engine 100 can drive the first drive shaft 411 or the second drive shaft 412 to rotate. For example, when the mechanical compressor 300 is connected to the first drive shaft 411, the engine 100 can drive the first drive shaft 411 to rotate. For another example, when the mechanical compressor 300 is connected to the second drive shaft 412, the engine 100 can drive the second drive shaft 412 to rotate, thereby driving the mechanical compressor 300 to operate and achieve cooling.

[0061] Second, the engine 100 is in the off state, which is the pure electric mode. If the air conditioner in the car is turned on, the first clutch 420 is disengaged, and the second clutch 414 is also disengaged. At this time, because the motor 200 and the mechanical compressor 300 are connected to the same drive shaft, the motor 200 can drive the mechanical compressor 300 to operate. For example, when the mechanical compressor 300 is connected to the first drive shaft 411, the motor 200 is also connected to the first drive shaft 411, thereby driving the mechanical compressor 300 to rotate by driving the first drive shaft 411 to achieve cooling. For another example, when the mechanical compressor 300 is connected to the second drive shaft 412, the motor 200 can drive the mechanical compressor 300 to rotate by driving the second drive shaft 412 to achieve cooling.

[0062] When the car is in form:

[0063] First, the engine 100 is in the starting state, which is the power mode. If the air conditioner in the car is turned on, the first clutch 420 is engaged, and the engine 100 can drive the first drive shaft 411 and the second drive shaft 412 to rotate. The mechanical compressor 300 and the motor 200 are connected to the same drive shaft.

[0064] If the mechanical compressor 300 is connected to the first drive shaft 411 and the second clutch 414 controls the first drive shaft 411 to cooperate with the transmission shaft 413, the engine 100 drives the vehicle and the mechanical compressor 300 to operate simultaneously; if the second clutch 414 controls the second drive shaft 412 to cooperate with the transmission shaft 413, the engine 100 can drive the vehicle while the motor 200 drives the mechanical compressor 300 by driving the first drive shaft 411.

[0065] If the mechanical compressor 300 is connected to the second drive shaft 412 and the second clutch 414 controls the first drive shaft 411 to cooperate with the transmission shaft 413, the engine 100 drives the vehicle to move, while the motor 200 drives the mechanical compressor 300 by driving the second drive shaft 412; if the second clutch 414 controls the second drive shaft 412 to cooperate with the transmission shaft 413, the engine 100 drives the vehicle to move and the mechanical compressor 300 to operate simultaneously.

[0066] Second, engine 100 is off, in pure electric mode. If the vehicle's air conditioner is activated, first clutch 420 is disengaged, and motor 200 drives the vehicle and mechanical compressor 300. Since mechanical compressor 300 and motor 200 are connected to the same drive shaft, controlling the engagement state of second clutch 414 allows motor 200 to directly drive both the vehicle and mechanical compressor 300.

[0067] In a possible implementation, the input shaft of the mechanical compressor 300 may be meshed with either the first drive shaft 411 or the second drive shaft 412 via gears, thereby ensuring the reliability and stability of the transmission of the drive shaft in the process of driving the mechanical compressor 300 .

[0068] Those skilled in the art will appreciate that the mechanical compressor 300 may include a main body and a compressor clutch, the compressor clutch may be disposed between the main body and the input shaft, and the compressor clutch may be connected to the input shaft.

[0069] It should be noted that in the embodiment of the present application, the coordination between the mechanical compressor 300 and the gearbox 410 can be achieved through a compressor clutch, so that the transmission between the two is maintained when the refrigeration function needs to be started, and the transmission between the two is disconnected when the refrigeration function is turned off.

[0070] In some embodiments, the gearbox 410 may further include a housing 415, and the second clutch 414, the transmission shaft 413 and the drive shaft may all be disposed inside the housing 415, while the mechanical compressor 300 and the motor 200 may all be disposed on the side of the housing 415, thereby ensuring the rationality of the arrangement and the convenience of assembly between the various components of the hybrid system, and improving assembly efficiency and space utilization.

[0071] It is understandable that the first drive shaft 411 , the second drive shaft 412 and the transmission shaft 413 may partially extend from the housing 415 so as to cooperate with the first clutch 420 , the motor 200 , the mechanical compressor 300 and other components.

[0072] In addition, the hybrid system provided in the present application may also include a battery 500, wherein the battery 500 is electrically connected to the motor 200, so that the motor 200 can be powered by the battery 500 to realize electric-driven operation of the vehicle, and at the same time, the mechanical compressor 300 can be driven by electricity in conjunction with the gearbox 410.

[0073] When applied to a car, the hybrid power system provided by the embodiment of the present application may further include a front drive axle 600 and a rear drive axle 700, and the drive shaft 413 is connected to either the front drive axle 600 or the rear drive axle 700 to ensure the reliability of the power output of the hybrid power system.

[0074] In addition, Figure 5 As shown, in the embodiment of the present application, the gearbox 410 can also be a continuously variable gearbox, and its specific implementation of the driving method of the mechanical compressor 300 is the same as the aforementioned technical solution type, which will not be repeated here.

[0075] An embodiment of the present application provides a hybrid power system, which includes an engine, a motor, a mechanical compressor and a transmission assembly. The transmission assembly includes a gearbox and a first clutch. The first clutch is connected between the engine and the gearbox, and the engine is connected to a first side of the first clutch. The gearbox includes a second clutch, a transmission shaft and at least one drive shaft. The drive shaft is connected to the second side of the first clutch. The motor and the mechanical compressor are both connected to the drive shaft. The second clutch is arranged between the transmission shaft and the drive shaft to control the connection or separation of the transmission shaft and the drive shaft, thereby ensuring that the compressor can be started to achieve cooling in different working modes and operating states of the hybrid vehicle while reducing the cost of the compressor.

[0076] An embodiment of the present application also provides a car, which includes a chassis and the hybrid power system of the above technical solution, wherein the hybrid power system is arranged on the chassis to drive the operation of the car.

[0077] It is understood that the hybrid system provides power for the operation of the vehicle and the vehicle air conditioner, wherein the vehicle can be driven by an engine, or by an electric motor, or by a combination of the engine and the electric motor.

[0078] In addition, the automobile provided in the embodiment of the present application is a hybrid vehicle. For example, it can be a series hybrid vehicle, a parallel hybrid vehicle, or a series-parallel hybrid vehicle. This embodiment does not make specific limitations on this, and its functions can be that of a passenger car or a truck.
