Referring to fig. 1 and 2, the utility model provides a distributed power system, include:

a control system 1;

a planetary gear mechanism 2 for distributing power, the planetary gear mechanism 2 including a ring gear 21, a sun gear 22 located at the center of the ring gear 21, and a planetary gear set 23 provided between the ring gear 21 and the sun gear 22, the planetary gear set 23 including a carrier 231 and a plurality of pinion gears 232 provided to the carrier 231;

the first driving device 3 is in transmission connection with the planet carrier 231 and is in communication connection with the control system 1;

a second driving device 4, wherein the second driving device 4 is in transmission connection with the sun gear 22 and is in communication connection with the control system 1;

a third drive means 5, the third drive means 5 being in driving connection with the ring gear 21 and being communicatively connected to the control system 1;

the power output mechanism 6 is in transmission connection with one of the ring gear 21, the sun gear 22 and the planet carrier 231;

the mode switching system 7, the mode switching system 7 includes a first locker 71 and a second locker 72, the first locker 71 and the second locker 72 are used for respectively limiting two of the ring gear 21, the sun gear 22 and the carrier 231 which are not in transmission connection with the power output mechanism 6, and the first locker 71 and the second locker 72 are respectively in communication connection with the control system 1.

In the present invention, one of the first driving device 3, the second driving device 4 and the third driving device 5 may be an engine or a motor; the engine can be one of an internal combustion engine (such as a reciprocating piston engine), an external combustion engine (such as a Stirling engine and a steam engine), a jet engine and an electric motor; the motor can be used as a generator and also can be used as a motor. That is, the first driving device 3 is an engine or a motor, the second driving device 4 is an engine or a motor, and the third driving device 5 is an engine or a motor, and there are six types of layout modes of the first driving device 3, the second driving device 4, and the third driving device 5.

The control system 1 is in communication connection with the first driving device 3, the second driving device 4 and the third driving device 5 respectively, so as to collect and control the operation states (such as the rotating speed, the power generation mode and the driving mode) of the driving devices; the control system 1 is in communication connection with the first locker 71 and the second locker 72, respectively, to acquire and control the action state (locking or unlocking) of the first locker 71 and the action state (locking or unlocking) of the second locker 72.

The basic motion principle of the planetary gear mechanism 2 described above is: when the ring gear 21 is fixed, the carrier 231 and the sun gear 22 rotate in the same direction; when the carrier 231 is fixed, the ring gear 21 and the sun gear 22 rotate in reverse; when the sun gear 22 is fixed, the ring gear 21 and the carrier 231 rotate in the same direction. In the planetary gear mechanism 2, a proportional relationship is formed between the sum of the rotation speeds of the ring gear 21 and the sun gear 22 and the rotation speed of the carrier 231, that is, the sum of the rotation speeds of the ring gear 21 and the second driving device 4 and the rotation speed of the first driving device 3. When the rotational speed of the first drive means 3 is fixed, an inverse relationship is formed between the rotational speed of the second drive means 4 and the rotational speed of the ring gear 21.

The planetary gear mechanism 2 described above is used to distribute power, that is:

when the first driving device 3 is an engine or a motor in a driving mode, the first driving device 3 may transmit power to the planet carrier 231 and then divide the power into two paths, one path of power may flow to the ring gear 21, and the other path of power may flow to the sun gear 22. When the first driving device 3 is a motor in the power generation mode, the first driving device 3 converts kinetic energy of the carrier 231 into electric energy.

The second driving device 4 is in transmission connection with the sun gear 22, and when the second driving device 4 is an engine or a motor in a driving mode, the second driving device 4 can transmit power to the planet carrier 231 and also can transmit power to the ring gear 21; when the second driving device 4 is a motor in the power generation mode, the second driving device 4 converts the kinetic energy of the sun gear 22 into electric energy.

The third driving device 5 is in transmission connection with the ring gear 21, and when the third driving device 5 is an engine or a motor in a driving mode, the third driving device 5 may transmit power to the carrier 231 or may transmit power to the sun gear 22. When the third drive means 5 is in the motor of the generating mode, the third drive means 5 converts the kinetic energy of the ring gear 21 into electric energy.

The power output mechanism 6 may be a running mechanism, a jacking mechanism, or a working mechanism in other motion forms. The power take-off 6 is in driving connection with one of the ring gear 21, the sun gear 22 and the planet carrier 231, i.e. one of the ring gear 21, the sun gear 22 and the planet carrier 231 can be used as a drive input for driving the power take-off 6.

Based on the transmission relationship, the control system 1 converts a preset speed to be reached by the power output mechanism 6 (if the power output mechanism 6 is a running mechanism, the preset speed of the power output mechanism 6 may be a running speed with respect to the ground) into a rotation speed that one of the ring gear 21, the sun gear 22, and the carrier 231 needs to reach. The current speed of the power output mechanism 6 can be changed at a change in the operation mode (power generation mode or drive mode) of the first drive device 3, the second drive device 4, and the third drive device 5. That is, the power take-off mechanism 6 can achieve gear shifting without the existing clutch and transmission in the distributed power system. The control system 1 can calculate how much power or rotational speed one or more of the first drive means 3, the second drive means 4 and the third drive means 5, which requires output power, needs to provide, based on relevant information such as the load.

The mode switching system 7 is used for changing the power distribution path of the distributed power system, the mode switching system 7 includes a first locker 71 and a second locker 72, the first locker 71 and the second locker 72 are used for respectively limiting two of the ring gear 21, the sun gear 22 and the carrier 231 which are not in transmission connection with the power output mechanism 6, and the action change of the first locker 71 and the second locker 72 can switch out a plurality of operation modes on the basis of the change of the type (type refers to an engine or a motor) of each driving device 5.

For example, in an assembly layout in which the first driving device 3 is an engine, the second driving device 4 and the third driving device 5 are both motors, and the power output mechanism 6 is in transmission connection with the ring gear 21, the distributed power system has the following operation modes: in the first mode, when the carrier 231 is locked by the first locker 71 and the sun gear 22 is released by the second locker 72, the sun gear 22 idles, and the third drive device 5 is in the drive mode and transmits power to the power output mechanism 6 through the ring gear 21. In the second mode, when the first locker 71 releases the carrier 231 and the second locker 72 releases the sun gear 22, the first driving device 3 transmits power to the carrier 231 and then divides the power into two paths, one path of power is transmitted to the second driving device 4 through the planetary gear 232 and the sun gear 22 in sequence, the second driving device 4 enters the power generation mode, and the other path of power is transmitted to the power output mechanism 6 through the planetary gear 232 and the ring gear 21 in sequence. At this time, it should be noted that: if the ring gear 21 is in a stationary state, i.e. the power take-off 6 is not operating, the power of the first drive means 3 can be transmitted to the second drive means 4 in its entirety, i.e. the power taken off by the first drive means 3 is used exclusively for generating electricity. In the third mode, when the carrier 231 is released by the first lock 71 and the sun gear 22 is locked by the second lock 72, the power transmission structure between the third drive device 5 and the ring gear 21 idles, and the power output from the first drive device 3 is transmitted to the power output mechanism 6 via the carrier 231, the pinion 232, and the ring gear 21 in this order. A fourth mode in which, when the carrier 231 is released by the first locker 71 and the sun gear 22 is locked by the second locker 72, the power output from the first drive device 3 is transmitted to the power output mechanism 6 through the carrier 231, the pinion 232, and the ring gear 21 in this order, and at the same time, the power output from the third drive device 5 is transmitted to the power output mechanism 6 through the ring gear 21; in the fifth mode, when the carrier 231 is released by the first lock 71 and the sun gear 22 is released by the second lock 72, the second drive device 4 is in the drive mode, and the power output from the first drive device 3 is transmitted to the power output mechanism 6 via the carrier 231, the pinion 232, and the ring gear 21 in this order, while the power output from the second drive device 4 is transmitted to the power output mechanism 6 via the sun gear 22, the pinion 232, and the ring gear 21 in this order. When the first driving device 3, the second driving device 4, the third driving device 5 and the power output mechanism 6 form other types of assembly layouts, the distributed power system can be switched to more operation modes, and details are not described here.

Therefore, the utility model discloses a distributed power system's technological effect as follows:

1. the overall structure of the distributed power system is very simple and convenient to arrange, and the first driving device 3, the second driving device 4 and the third driving device 5 are respectively in transmission connection with the planetary gear mechanism 2, so that a clutch and a transmission are omitted, the manufacturing cost and the maintenance cost are greatly reduced, the weight is reduced, and the installation layout is facilitated;

2. the combined use of the planetary gear mechanism 2 and the mode switching system 7, plus the types of the first driving device 3, the second driving device 4, and the third driving device 5, can be selected, so that the power distribution of the distributed power system is flexible; under the regulation of the mode switching system 7, the distributed power system has various working modes and rich series-parallel combination types;

3. the distributed power system has a self-repairing function, and the working mode of the distributed power system is actively adjusted when self-inspection is started or power transmission parts are damaged. That is, unlike the fixed connection of the conventional multi-power, multi-output system or the connection manner by a clutch, all the inputs and outputs of the distributed power system can be flexibly adjusted by locking a certain component of the planetary gear mechanism 2 by the control system 1 to flexibly adjust the power flow direction and adjusting the load damping of a certain component of the planetary gear mechanism 2 to flexibly adjust the power distribution ratio. All power is transmitted to the power output mechanism 6 through the gear transmission structure, the control system 1 collects the working conditions of the first driving device 3, the second driving device 4, the third driving device 5 and the mode switching system 7 in real time, and through controlling the locking state and the releasing state of the first locking device 71 and the second locking device 72, the power distribution path of the distributed power system can be enabled to avoid the driving device, the locking device or the driving battery with faults, so that the overall operation efficiency of the first driving device 3, the second driving device 4 and the third driving device 5 is improved, and the power distribution path of the distributed power system can be automatically monitored, automatically repaired and adjusted to enable the distributed power system to output power efficiently and reliably all the time. Specifically, in an embodiment of the distributed power system, that is, in an assembly layout in which the first driving device 3 is an engine, the second driving device 4 and the third driving device 5 are both motors, and the power output mechanism 6 is in transmission connection with the gear ring 21, the control system 1 monitors whether the working conditions of the first driving device 3, the second driving device 4, the third driving device 5 and the mode switching system 7 are normal or not in real time after being started. If the third driving device 5 is damaged, the distributed power system is automatically switched into a hybrid mode of an engine and a motor under the regulation and control of the control system 1; if the second driving device 4 is damaged, the distributed power system is automatically switched into a hybrid mode of an engine and a motor under the regulation and control of the control system 1; if the first driving device 3 is found to be damaged, the distributed power system is automatically switched into a hybrid mode of the double motors under the regulation and control of the control system 1. If the third driving device 5 cannot obtain electric energy, under the regulation and control of the control system 1, the distributed power system is automatically switched into a series-parallel hybrid mode in which the motors drive, one of the motors generates electricity and the other motor drives; if the first locker 71 or the second locker 72 is found to be damaged, the distributed power system can automatically switch to an operating mode without the locker being locked under the control of the control system 1.

As a power distribution method of the distributed power system: two of the first driving device 3, the second driving device 4, and the third driving device 5 are motors, and the remaining one of the first driving device 3, the second driving device 4, and the third driving device 5 is an engine.

Further, in order to coordinate the electric energy between the two electric machines, the distributed power system further includes a driving battery 9, the driving battery 9 is electrically connected to two of the first driving device 3, the second driving device 4 and the third driving device 5, respectively, and the driving battery 9 is communicatively connected to the control system 1.

The above-mentioned drive battery 9 is used for supplying power to the motor or storing electric energy generated by the motor. The control system 1 is connected to the drive battery 9 in a communication manner, and can acquire the SOC value (the ratio of the remaining dischargeable electric quantity to the electric quantity in its fully charged state) of the drive battery 9 in real time. The SOC of the driving battery 9 is divided into a charged state, a low-charged state and an empty state, the SOC of the charged state (i.e. the ratio of the remaining capacity to the battery capacity, and the SOC of the driving battery 9 is adjustable by a user) ranges from greater than 25%, the SOC of the low-charged state ranges from 10% to 25%, and the SOC of the empty state ranges from less than 10%. The power output mechanism 6 is divided into a low speed, a medium speed, and a high speed that become larger in order with respect to the speed per hour of the road surface, and the low speed is in a range of less than 42Km/h, the medium speed is in a range of 42 to 82Km/h, and the high speed is in a range of more than 82 Km/h.

Based on the above-described SOC value of the drive battery 9 and the speed per hour of the power output mechanism 6, the operation modes of the distributed power system include the following modes, thereby reducing the total energy consumption of the distributed power system:

when the power output mechanism 6 is running at a low speed, or the drive battery 9 is in a charged state and the power output mechanism 6 is running at a medium speed (simply referred to as a low speed and a charged medium speed, hereinafter referred to in the form of short): the first locker 71 locks the carrier 231, the second locker 72 releases the sun gear 22, the sun gear 22 idles, and the third driving device 5 is in the driving mode and transmits power to the power output mechanism 6 through the ring gear 21.

When the drive battery 9 is in a low-power state and the power output mechanism 6 is running at a medium speed (simply referred to as low-power medium speed): the first locker 71 releases the carrier 231, the second locker 72 releases the sun gear 22, the first driving device 3 transmits power to the carrier 231 and then divides the power into two paths, wherein one path of power is transmitted to the second driving device 4 through the planetary gear 232 and the sun gear 22 in sequence, so that the second driving device 4 enters a power generation mode, and the other path of power is transmitted to the power output mechanism 6 through the planetary gear 232 and the ring gear 21 in sequence.

When the power output mechanism 6 runs at high speed (simply referred to as high speed): the first locker 71 releases the carrier 231, the second locker 72 locks the sun gear 22, the power transmission structure between the third driving device 5 and the ring gear 21 can idle, and the power output from the first driving device 3 is transmitted to the power output mechanism 6 through the carrier 231, the pinion 232, and the ring gear 21 in this order.

When the power output mechanism 6 is in the first motion mode and the drive battery 9 is in a charged state (simply referred to as first motion charged): when the carrier 231 is released by the first locker 71 and the sun gear 22 is locked by the second locker 72, the power output from the first drive device 3 is transmitted to the power output mechanism 6 through the carrier 231, the pinion 232, and the ring gear 21 in this order, and at the same time, the power output from the third drive device 5 is transmitted to the power output mechanism 6 through the ring gear 21.

When the power output mechanism 6 is in the second motion mode and the drive battery 9 is in a charged state (simply referred to as second motion charged): the first lock 71 releases the carrier 231, the second lock 72 releases the sun gear 22, the second drive device 4 is in the drive mode, the power output from the first drive device 3 is transmitted to the power output mechanism 6 sequentially through the carrier 231, the pinion 232, and the ring gear 21, and at the same time, the power output from the second drive device 4 is transmitted to the power output mechanism 6 sequentially through the sun gear 22, the pinion 232, and the ring gear 21.

In order to switch further operating modes, the above-described mode switching system 7 further includes a third lock-up device 73, the third lock-up device 73 being configured to restrict one of the ring gear 21, the sun gear 22 and the carrier 231, which is drivingly connected to the power take-off mechanism 6, the third lock-up device 73 being communicatively connected to the control system 1. As an embodiment of the above-described mode switching system 7: in an assembly configuration in which the first drive device 3 is an engine, the second drive device 4 and the third drive device 5 are both motors, and the power take-off 6 is drivingly connected to the ring gear 21, the first lock 71 is used to restrain the carrier 231, the second lock 72 is used to restrain the sun gear 22, and the third lock 73 is used to restrain the ring gear 21. In use, the released or locked state of the third latch 73 is controlled by the control system 1. For example, when the user needs to stop the power output mechanism 6, the user sends a stop instruction to the control system 1 (for example, the driver puts the vehicle into the P range), and the control system 1 controls the third locker 73 to lock the ring gear 21.

In order to prevent the power take-off mechanism 6 from moving further, the mode switching system 7 further includes a fourth latch 74 (e.g., a caliper), a brake trigger 75 (e.g., a brake stepped by the driver) operated by the user, and a position detector for detecting a position of the brake trigger 75, the fourth latch 74 is used for limiting the power take-off mechanism 6, the fourth latch 74 is in transmission connection with the brake trigger 75, and the position detector is in communication connection with the control system 1.

The position detector may collect the position information of the brake trigger 75 in real time, and when the positions of the brake trigger 75 are different, the position detector may send different motor operation commands to the control system 1. For example, when the brake trigger 75 is a pedal, the movement stroke of the brake trigger 75 is divided into two sections, and when the brake trigger 75 is located at one of the two sections, the position detector sends a motor power generation instruction to the control system 1, so that the control system 1 controls one of the first driving device 3, the second driving device 4, and the third driving device 5 to enter a power generation mode. Furthermore, the brake trigger 75 controls the degree of locking of the fourth lock 74, since the fourth lock 74 is in driving connection with the brake trigger 75 during the entire stroke of the brake trigger 75.
