Fig. 2 schematically illustrates a structure of the planetary gear accelerator-based dual power compressor according to an embodiment. Fig. 2 is a schematic structural diagram of a dual-power compressor based on a planetary gear accelerator according to an embodiment of the present invention; as shown in figure 2 of the drawings, in which,

the double-power compressor system comprises a compressor shell 8, a belt wheel mechanism 2, an end cover 9, a compression mechanism 3 which is arranged in the compressor shell 8 and compresses fluid by means of rotary motion, a sun wheel rotary driving shaft 31 connected to the compression mechanism 3 and a motor mechanism 5 which penetrates through the sun wheel rotary driving shaft 31; the compression mechanism 3 is connected with the motor mechanism 5 and the belt pulley mechanism 2 through a sun wheel rotating driving shaft 31; wherein the belt wheel mechanism 2 is connected with the sun wheel rotating driving shaft 31 through the planetary gear accelerator 11; the belt pulley mechanism 2 comprises a belt pulley 21 and an electromagnetic clutch 22 for controlling the belt pulley 21 to pull in and rotate; and a control unit 7 for controlling the belt pulley mechanism 2, the motor mechanism 5 and the compression mechanism 3.

Taking a scroll compressor in a truck compressor as an example, the rotating speed of a fuel engine in a normal running process is 1600-2200 r/min, the problem of leakage of a scroll fluid needs to be considered, the refrigerating capacity requirement needs to be ensured, and meanwhile, the belt wheel compressor needs to be designed to have a large displacement of 70cc or even 120cc because the output rotating speed of the fuel engine is low; when the rotating speed of the fuel engine is constant, the technical effect of increasing the rotating speed of the scroll by 3-5 times can be achieved by adding the planetary gear accelerator, and if the refrigerating capacity is equal to 70-120 cc, the discharge capacity of a matched compressor can be reduced to 20-35 cc. For example, when the displacement of the compressor is reduced to 20cc, even if the fuel engine is in idle speed (for example, the fuel engine is idle at 500rpm, the planetary gear accelerator is input at low speed, and the rotating speed of the scroll plate is increased by 3 times through the planetary gear accelerator, so that the rotating speed of the scroll plate reaches 1500 rpm), the conditions that the fluid leakage of the scroll plate and the refrigerating capacity is insufficient due to the low rotating speed of the fuel engine can not be generated, and the problem that the required refrigerating capacity can be met by offsetting the fluid leakage in the low rotating speed through increasing the displacement of the scroll compressor is fundamentally solved.

In a specific embodiment, in order to prevent the rotor 52 of the motor mechanism 5 from rotating in the reverse direction, the motor mechanism 5 and the sun gear rotation driving shaft 31 are provided with one-way bearings 101. The one-way bearing, i.e. the overrunning clutch, also referred to as one-way clutch, may be a wedge, ratchet or roller clutch or the like, wherein the one-way clutch has an optimal technical performance. Specifically, the bearing housing 102 is subjected to axial forces that may be experienced. Specifically, the motor mechanism 5 is connected to the sun gear rotation driving shaft 31 through a transmission assembly 10 for preventing the rotor of the motor mechanism from rotating reversely, wherein the transmission assembly 10 includes a one-way bearing 101, a bearing housing 102 and a needle bearing 103, and the one-way bearing 101, the bearing housing 102 and the needle bearing 103 are sequentially sleeved on the sun gear rotation driving shaft 31. The bearing sleeve 102 includes a sleeve portion 1021 and a step portion 1022 having a diameter larger than the sleeve portion 1021; the sleeve portion 1021 has an outer surface and an inner surface; the output end of the motor mechanism 5 is connected with the outer surface of the sleeve part 1021; the sun gear rotation drive shaft 31 is connected to the inner surface of the sleeve portion 1021 by a needle bearing 103 in a rolling manner; an annular first step surface 1023 for abutting against the one-way bearing is formed at the boundary of the step part 1022 and the sleeve part 1021; the inner ring of the one-way bearing 101 is fixedly connected to the sun gear rotation drive shaft 31, and the outer ring of the one-way bearing 101 is fixedly connected to the step part 1022. The modified step part 1022 as the present embodiment is extended outward to form a ring-shaped second step surface (not shown in the drawings), and the second step surface is connected with a damper (not shown in the drawings) for increasing the rotational resistance of the bearing housing. The belt pulley mechanism 2 is sleeved on a sun wheel rotating driving shaft 31 coated with a compressor shell 8, and the compressor shell 8 is in rolling connection with the sun wheel rotating driving shaft 31; the motor mechanism 5 includes a stator 51 and a rotor 52 with a built-in magnetic steel 53, the stator 51 is in interference fit with the compressor housing 8, and the rotor 52 is fixedly connected with the outer surface of the sleeve portion 1021 of the bearing housing 102. The stator and the rotor are combined to constitute a motor drive mechanism, the sun gear rotation drive shaft 31 is inserted into the rotor 52 and connected to the rotor 52, and the rotor 52 rotates integrally with the sun gear rotation drive shaft 31.

By adopting the one-way bearing 101, when the pulley 21 is used as power transmission scene, the rotor 52 part of the motor mechanism 5 does not generate relative motion when the pulley 21 is used for transmission through the one-way bearing 101, and further does not generate reluctance torque to lose the power of a fuel engine; when the electromagnetic clutch 22 of the belt pulley mechanism 2 is in the idle running state of power failure in the scene of the motor mechanism 5 as power transmission, the rotor 52 of the motor mechanism normally runs, and the forward rotation locking action of the one-way bearing 101 drives the sun gear to rotate the driving shaft 31 to perform the refrigeration work of driving the scroll plate, so that the compressor normally runs.

In another specific embodiment, in order to prevent the rotor 52 of the motor mechanism 5 from rotating reversely, the motor controller 71 may be modified to control the stator 51 of the motor mechanism 5 to be energized, so that the stator 51 generates reluctance torque to the rotor 52 of the motor mechanism 5 to prevent the rotor 52 from rotating.

Specifically, any two or three phases of the three phase lines of the stator 51 of the motor mechanism 5 are controlled to be conducted through the motor controller 71, so that the stator 51 generates a reinforced magnetic resistance to the rotor 52, and the phenomenon that the one-way bearing 101 is overtaken and not separated during the high-speed operation of the belt pulley mechanism 2 is further eliminated. Wherein the motor controller is an electronic circuit for controlling the permanent magnet motor. In short, in the dual-power compressor based on the planetary gear accelerator, in which the belt pulley and the permanent magnet motor share one set of scroll plate, under the scene of using the belt pulley as a power source, the controller brakes the rotor of the motor mechanism, so as to achieve the technical effect that the rotor has reluctance torque relative to the stator.

Fig. 3 illustrates the structure of the control unit of the planetary gear accelerator-based dual power compressor according to one embodiment. Fig. 3 is a schematic structural diagram of a control unit of a planetary gear accelerator-based dual power compressor according to an embodiment of the present invention; as shown in figure 3 of the drawings,

the control unit 7 includes a motor controller 71 for controlling the stator 51 of the motor mechanism 5 to be energized so that the stator 51 generates reluctance torque to the rotor 52 of the motor mechanism 5 to prevent the rotor 52 from rotating.

The control unit 7 further comprises an overload prevention module 72 for disengaging the electromagnetic clutch 22 from the pulley 21 when the rotational speed of the fuel engine 1 exceeds a set rotational speed threshold. In a specific embodiment, still taking a truck as an example, in a scene of acceleration or climbing of the truck, the rotation speed of the fuel engine can reach 6000 to 7000r/min, and after the acceleration by the planetary gear accelerator, the rotation speed can reach 21000rpm, which is obviously beyond the bearing range of the compressor. In order to protect the compressor, after detecting that the rotation speed of the fuel engine exceeds the set rotation speed threshold value of 2000rpm, the overload prevention module 72 controls the electromagnetic clutch 22 to be disconnected, that is, when the rotation speed of the fuel engine is higher than the set value, the compressor stops working, and the air conditioner is temporarily stopped. And the problem of high rotating speed of the planetary gear after acceleration caused by torque input of the fuel engine is further solved.

The control unit 7 further comprises a power switching module 73, wherein the power switching module 73 is used for switching the motor mechanism 5 as a power source of the compression mechanism 3 when the separation time of the electromagnetic clutch 22 and the belt pulley 21 exceeds a set time threshold and the rotating speed of the fuel engine 1 exceeds a set rotating speed threshold. Still taking the truck as an example, because the fuel engine speed is too high, the electromagnetic clutch 22 is turned off, causing the compressor to stop operating, temporarily deactivating the air conditioner. To further ensure comfort in the cabin, a time threshold for the compressor deactivation time is set, such as 3 minutes. If the off time of the electromagnetic clutch 22 reaches the set time threshold value of 3min, the detected rotating speed of the fuel engine is still higher than 2000 rpm; the electric mechanism 5 is directly started to carry out compressor refrigeration until the rotating speed drop value of the fuel engine is below the set rotating speed threshold value.

According to the double-power compressor based on the planetary gear accelerator, the belt wheel mechanism, the compression mechanism, the sun wheel rotating driving shaft and the motor mechanism are coaxially arranged, so that the compressor has two driving modes; the belt pulley and the motor mechanism share one set of scroll plate, and the effect of improving the rotating speed of the scroll plate is achieved through the planetary gear accelerator, so that the compressor with smaller displacement is adopted on the premise of not influencing the using effect, and the working state of the compressor can be rapidly switched between an electric mode and a fuel engine belt pulley transmission mode. Through adopting one-way bearing or adopting machine controller to realize that the rotor rotates in belt pulley transmission, stopped because of the phenomenon that produces magnetic resistance moment of torsion loss fuel engine power, and then realized two kinds of driving method's independent function, motor rotor rotates when having avoided adopting belt pulley drive, and then has avoided extra power loss, realizes the maximize of band pulley power utilization, has reduce cost, realizes the whole lightweight of device, the technological effect of easily installing. Furthermore, a dual power compressor based on a planetary gear accelerator of the present invention can be implemented in a dual power compressor model of the prior art without extensive retrofitting. Thus, the cost of developing a new compressor model and retrofitting an existing compressor is reduced.
