Example one

Fig. 1 is a schematic structural diagram of a vehicle cooling system of a hybrid all-terrain vehicle according to an embodiment of the present invention. Referring to fig. 1, a cooling system for a vehicle according to an embodiment includes: a power system 100, a motor radiator 30 and a water pump 50.

Wherein the front wheel is positioned at the front side of the frame, and the rear wheel is positioned at the rear side of the frame. The power system can be fixed on the frame, and comprises a motor and an engine 40; the engine 40 is used to drive a motor for generating electric power or for outputting power to the front wheels or the rear wheels, and the motor is used to generate electric power or for outputting power to the front wheels or/and the rear wheels under the drive of the engine 40. Specifically, the motor is connected with the engine and used for generating electric energy under the driving of the engine and outputting power to the front wheels and the rear wheels together with the engine.

The motor is internally provided with a motor cooling channel; the motor radiator 30 is fixed on the frame, the motor radiator 30 comprises a motor radiator liquid inlet 31 and a motor radiator liquid outlet 32, and the motor radiator liquid inlet 31, the motor cooling channel 32 and the motor radiator liquid outlet 32 are sequentially communicated to form a motor cooling system.

The water pump 50 is connected in the motor cooling system, and the height of the water pump 50 from the ground is less than or equal to the height of two end parts of the motor cooling channel from the ground; and/or the height of the water pump 50 from the ground is less than or equal to the height of the motor radiator liquid inlet 31 and the motor radiator liquid outlet 32 from the ground. Thereby, the water pump 50 is located at the lowest position of the motor cooling system. Since the water flows downward, the water pump 50 is disposed at the lowest position, so that the water pump 50 can rapidly pump the coolant at the motor radiator 30 to all parts of the motor cooling system, thereby maximally improving the cooling efficiency.

The hybrid all-terrain vehicle of the present embodiment is driven by a hybrid of fuel (gasoline, diesel, etc.) and electrical energy. More specifically, the vehicle of the present embodiment may be an extended range vehicle.

The embodiment of the utility model provides a hybrid all terrain vehicle, the motor has motor cooling channel, motor radiator inlet, motor cooling channel, communicate formation motor cooling system in proper order with motor radiator liquid outlet, the position of water pump in motor cooling system is in motor cooling system's extreme low position, make the water pump can be fast with motor radiator's coolant pump to motor cooling system, make whole motor cooling system's circulation efficiency higher, effectively improved motor radiating efficiency, make the motor can obtain quick heat dissipation, and then effectively improve the life of motor, guarantee all terrain vehicle's driving safety. Specifically, the motors may include a first motor 10 and a second motor 20, the second motor 20 of the present embodiment may be connected to the engine 40 and may be driven by the engine 40 to generate electric energy, and the second motor 20 may be electrically connected to the first motor 10, so that the first motor 10 outputs power to the front wheel or the rear wheel through the electric energy generated by the second motor 20, specifically, the second motor 20 provides electric energy to the first motor 10, and the first motor 10 is configured to be in driving connection with an axle (not shown) of the vehicle, so that the power of the first motor 10 is transmitted to the wheel. Since the engine 40 can generate power for the second motor 20 and the second motor 20 can provide power for the first motor 10, the endurance mileage of the whole vehicle is increased.

Specifically, the height of the water pump 50 from the ground is less than or equal to the height of the two ends of the first motor cooling channel from the ground, and/or the height of the water pump 50 from the ground is less than or equal to the height of the two ends of the second motor cooling channel from the ground.

The first motor 10 may have a first motor cooling passage therein and the second motor 20 may have a second motor cooling passage therein. The first motor cooling channel may be a pipeline disposed in the first motor 10, and may also be a cavity channel formed by an inner wall surface of the first motor 10, and the second motor cooling channel may be a pipeline disposed in the second motor 20, and may also be a cavity channel formed by an inner wall surface of the second motor 20, which is not particularly limited in this embodiment.

The motor radiator 30 includes a motor radiator inlet 31 and a motor radiator outlet 32, and the motor radiator inlet 31, the first motor cooling channel, the second motor cooling channel are communicated with the motor radiator outlet 32 to form a motor cooling system. The coolant is routed through the motor radiator 30, the first motor cooling channel, and the second motor cooling channel to cool and dissipate the first motor 10 and the second motor 20.

The water pump 50 is provided in the motor cooling system, and the water pump 50 is located at the lowest position of the motor cooling system. Since the water flows downward, the water pump 50 is disposed at the lowest position, so that the water pump 50 can rapidly pump the coolant at the motor radiator 30 to all parts of the motor cooling system, thereby maximally improving the cooling efficiency.

The motor radiator 30 may further be connected to a liquid feeding tank 30a, specifically, one end of the liquid feeding tank 30a may be communicated to the motor radiator 30 through a vent pipe 30b, the other end of the liquid feeding tank 30a may be connected to a liquid feeding pipe 30c, and the liquid feeding pipe 30c may be disposed between the water pump 50 and the liquid outlet 32 of the motor radiator.

Specifically, the charging tank 30a is mainly used to replenish the circulating cooling line with a circulating liquid that does not flow into the charging tank 30a while circulating in the circulating cooling line. Since the other end of the liquid feeding pipe 30c is communicated between the water pump 50 and the radiator outlet 3b, the circulating liquid flowing into the circulating cooling line from the liquid feeding tank 6 can flow to the motor cooling system under the driving of the water pump 50 without passing through the motor radiator 30.

Since some bubbles are inevitably generated when the cooling liquid circulates in the circulating cooling system, the bubbles in the circulating cooling system can be effectively discharged by providing the vent pipe 30b, so as to ensure that the cooling liquid can have a good heat absorption function. In this embodiment, the end of the vent pipe 30b communicating with the charging tank 30a may communicate with the filler port of the charging tank 30a to prevent the circulating liquid from flowing into the vent pipe 30b when the level of the coolant in the charging tank 30a is higher than the set level of the end of the vent pipe 30b communicating with the charging tank 30 a. Of course, in other embodiments, the liquid tank 30a and the vent pipe 30b may not be provided.

The motor radiator liquid outlet 32 is communicated with a first end of the first motor cooling channel, the motor radiator liquid inlet 31 is communicated with a first end of the second motor cooling channel, and a second end of the first motor cooling channel is communicated with a second end of the second motor cooling channel. It should be noted that the communication described herein includes direct communication, and may also include indirect connection. Because the motor radiator liquid outlet 32 is communicated with the first end of the first motor cooling channel, and the radiator liquid inlet 3b is communicated with the first end of the second motor cooling pipeline, when the cooling liquid circularly flows in the circulating cooling pipeline, the cooling liquid flowing out of the radiator liquid outlet 32 firstly passes through the first motor 10, then passes through the second motor 20, and finally flows into the motor radiator 30 from the motor radiator liquid inlet 31 for heat dissipation, therefore, a large amount of heat generated by the operation of the first motor 10 and the second motor 20 can be brought to the motor radiator 30, so that the heat is dissipated to the external environment through the motor radiator 30, the heat can be effectively dissipated to the first motor 10 and the second motor 20, the service life of the motors can be prolonged, and the driving safety of the all-terrain vehicle can be ensured.

In addition, since the second motor 20 is used for generating power and converting mechanical energy into electrical energy, and the first motor 10 is used as a driving motor, and the heat generated by the second motor 20 for generating power is greater than the heat generated by the first motor 10, in the motor cooling system of the embodiment, the cooling liquid firstly absorbs the heat generated by the first motor 10 with relatively low temperature and then absorbs the heat generated by the second motor 20 with relatively high temperature, so that the heat transfer efficiency is the highest, and the cooling effect is the best.

Further, as shown in fig. 1, the vehicle cooling system of the present embodiment further includes a controller 60, the controller 60 is connected to the motor cooling system, the controller 60 has a controller cooling channel therein, and the height of the water pump 50 from the ground is less than or equal to the height of the two ends of the controller cooling channel from the ground. The controller cooling channel may be in series between the motor radiator outlet 32 and the first motor cooling channel; the motor radiator liquid outlet 32 is communicated with a first end of the controller cooling channel, and a second end of the controller cooling channel is communicated with a first end of the first motor cooling channel.

In this embodiment, the controller 60 may be configured to cooperate with the first motor 10 and the second motor 20, and the controller 60 may have a plurality of control functions, for example, the controller 60 may have a first control terminal and a second control terminal, the first control terminal is connected to the first motor 10, and the second control terminal is connected to the second motor 20, so that the electric energy generated by the first motor 20 is modulated by the controller 60 and then transmitted to the first motor 10. In addition, the controller 60 may also be electrically connected to other electrical control components of the entire vehicle to implement the entire vehicle control.

Because controller 60 also can produce certain heat under operating condition, consequently, set up controller cooling channel in controller 60 inside, with controller cooling channel access motor cooling system for motor cooling system's cooling water is through controller 60 in order to dispel the heat to controller 60, improves controller 60's life, avoids the vehicle to appear because of controller 60 damages the condition emergence that suddenly fails to lead to out of control because of the high temperature.

Further, since the heat generated by the controller 60 is smaller than the heat generated by the first motor 10 and the second motor 20, the controller 60 of the present embodiment is disposed between the motor radiator 30 and the first motor 10, and after the coolant that releases heat at the motor radiator 30 flows out from the motor radiator 30, the coolant passes through the controller 60, the first motor 10 and the second motor 20 in sequence, and then returns to the motor radiator 30, wherein the heat generated by the operation of the controller 60 is less than the heat generated by the operation of the first motor 10 and less than the heat generated by the operation of the second motor 20, so that the controller 60, the first motor 10 and the second motor 20 can perform heat dissipation reasonably and effectively, and the cooling effect of the coolant is the best.

In addition to the above embodiment, further, as shown in fig. 1, a water pump 50 may be provided between the second end of the controller cooling passage and the first end of the first motor cooling passage. The arrangement of the water pump 50 can accelerate the circulation efficiency of the cooling liquid and ensure the heat dissipation speed. The water pump 50 is arranged in front of the first motor 10 and the second motor 20, because the first motor 10 and the second motor 20 have more heat during operation, and the water pump 50 is arranged at a position closer to the first motor 10 and the second motor 20, the cooling liquid can be rapidly pumped to the first motor 10 and the second motor 20 with higher temperature, and the first motor 10 and the second motor 20 can rapidly dissipate heat.

Of course, in other embodiments, the water pump 50 may be disposed between the motor radiator outlet 32 and the first end of the controller cooling passage. Alternatively, the water pump 50 is disposed between the second end of the second motor cooling channel and the second end of the first motor cooling channel; alternatively, the water pump 50 is disposed between the motor heat sink inlet 32 and the first end of the second motor cooling channel. The water pump 50 may be disposed at any position in the motor cooling system, as long as it can rapidly pump the coolant at the motor radiator 30 to the motor cooling system, and the embodiment is not particularly limited.

Further, as shown in fig. 1, the vehicle cooling system provided in the present embodiment further includes: an engine radiator 70. The engine radiator 70 includes an engine radiator inlet 71 and an engine radiator outlet 72. The engine 40 has an engine cooling passage therein, and an engine radiator liquid outlet 72, a first end of the engine cooling passage, a second end of the engine cooling passage and an engine radiator liquid inlet 71 are sequentially communicated to form an engine cooling system.

Because engine 40 also can produce a large amount of heats in the course of the work to the heat is more, consequently through independently setting up the engine cooling system who is used for the heat dissipation to engine 40 for the cooling of engine 40 and the cooling of motor are independent each other, and are not influenced by each other, thereby have promoted the radiating effect of engine 40 and motor effectively, make vehicle power sufficient.

Specifically, the engine cooling system of the present embodiment includes at least the engine 40, the engine radiator 70, and the engine cooling passage; the motor cooling system includes a motor, a motor heat sink 30, and a motor cooling channel. By arranging the motor cooling system and the engine cooling system side by side is meant that the motor cooling system and the engine cooling system are arranged side by side as a whole, and not every component is arranged side by side along the width direction of the vehicle, in this embodiment, at least the motor radiator 30 and the engine radiator 70 can be arranged side by side along the width direction of the vehicle, and the structure is compact and the layout is reasonable.

In the present embodiment, the engine radiator 70 and the motor radiator 30 may be identical in structure. The term "identical structure" means that the engine radiator 70 and the motor radiator 30 have the same size and shape, the engine radiator 70 and the motor radiator 30 have the same structure, and the manufacturing and design cost of the radiators can be reduced, the engine radiator 70 and the motor radiator 30 can be reused, the engine radiator 70 and the motor radiator 30 have the same structure, and the engine radiator 70 and the motor radiator 30 are arranged side by side in the width direction of the vehicle, so that the weight distribution of the left side and the right side of the vehicle is relatively balanced, and the balance and the stability of the vehicle are improved to a certain extent.

In some embodiments, the engine radiator 70 and the motor radiator 30 may be detachably coupled with the frame S of the vehicle.
