Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

An all-terrain vehicle 100 according to an embodiment of the invention is described below with reference to fig. 1-3.

As shown in fig. 1 and 2, an all-terrain vehicle 100 according to an embodiment of the invention includes: frame 10, engine 20, power motor 30, first radiator 40 and second radiator 50, engine 20 is disposed on frame 10, power motor 30 is disposed on frame 10, for example, power motor 30 is disposed on frame 10 through engine 20, and power motor 30 may be fixed on one side of engine 20 through a connecting flange. The power motor 30 may be a pure motor or a power generator.

The first radiator 40 and the second radiator 50 are both provided on the frame 10, and the first radiator 40 is connected to the engine 20 in a fluid path, and the second radiator 50 is connected to the power motor 30 in a fluid path. It is understood that a fluid line pipe is connected between the first radiator 40 and the engine 20, so that the coolant can flow between the first radiator 40 and the engine 20, and when the engine 20 is in operation, the coolant with high temperature can flow into the first radiator 40, and the first radiator 40 can effectively dissipate heat, so that the temperature of the coolant can be lowered, and the coolant can be returned to the engine 20. A liquid pipeline is connected between the second radiator 50 and the power motor 30, so that the cooling liquid can flow between the second radiator 50 and the power motor 30, when the power motor 30 works, the high-temperature cooling liquid can flow into the second radiator 50, the second radiator 50 can effectively radiate heat, the temperature of the cooling liquid can be reduced, and then the cooling liquid flows back to the power motor 30. It should be noted that the optimal operating temperatures of the engine 20 and the power motor 30 are different.

Therefore, the first radiator 40 can solely radiate heat for the coolant of the engine 20, and the second radiator 50 can solely radiate heat for the coolant of the power motor 30, so that the engine 20 and the power motor 30 can be at proper working temperatures, and the engine 20 and the power motor 30 are high in working efficiency and do not interfere with each other.

Specifically, as shown in fig. 3, the first radiator 40 is disposed at the front portion of the frame 10, and the second radiator 50 is disposed on the front surface of the first radiator 40. For example, the second radiator 50 is disposed at the upper half portion of the front surface of the first radiator 40, so that the first radiator 40 and the second radiator 50 can be disposed together, the overall arrangement of the radiators on the frame 10 can be facilitated, the installation space of the second radiator 50 does not need to be designed separately, the heat dissipation of the first radiator 40 and the second radiator 50 can be facilitated, and the working temperatures of the engine 20 and the power motor 30 can be ensured.

Wherein, when the first radiator 40 and the second radiator 50 are installed, the following installation can be performed: first radiator 40 is mounted to frame 10 using fasteners, and then second radiator 50 is placed on a front surface, e.g., the upper half, of first radiator 40 using fasteners, such that the two radiators are centrally located and integrated to a high degree, which may facilitate the overall layout of atv 100. In addition, when the radiator is maintained and replaced, the second radiator 50 can be detached firstly, and then the first radiator 40 can be detached, so that the maintenance and replacement are convenient, and the efficiency is high.

Further, atv 100 further comprises: and a cooling fan (not shown) disposed at a front portion of the frame 10 and located behind the first radiator 40. The cooling fan can promote the outside air to flow and exchange heat at the first radiator 40 and the second radiator 50, so as to take away the temperature of the coolant in the first radiator 40 and the second radiator 50, and further can be beneficial to improving the working efficiency of the engine 20 and the power motor 30.

According to an alternative embodiment of the present invention, as shown in fig. 2, atv 100 further comprises: and the controller 60 is arranged on the frame 10, the controller 60 is electrically connected with the power motor 30, and the controller 60 is also connected with the liquid path of the second radiator 50. That is, the controller 60 can control the power motor 30, and the controller 60 and the power motor 30 share the second heat sink 50 for heat dissipation. This can reduce the number of radiators and can satisfy the heat dissipation requirements of controller 60 and power motor 30.

Further, as shown in fig. 2, the controller 60 is located at the front upper side of the power motor 30, a controller water inlet pipe 61 is connected between the second radiator 50 and the controller 60, a motor water inlet pipe 31 is arranged between the controller 60 and the power motor 30, and a motor water outlet pipe 32 is arranged between the power motor 30 and the second radiator 50. That is, the coolant from the second radiator 50 flows through the controller 60, then flows through the power motor 30, and finally flows back to the second radiator 50. In this way, the temperature of the controller 60 and the power motor 30 can be reduced step by step, the controller 60 and the power motor 30 can be at an appropriate working temperature, and the working efficiency of the controller 60 and the power motor 30 can be high. Wherein, the controller 60 and the power motor 30 are internally provided with pipelines or liquid plates.

As shown in fig. 2, the controller water inlet pipe 61, the motor water inlet pipe 31 and the motor water outlet pipe 32 are located on the same side of the controller 60. That is to say, the pipeline between the power motor 30, the controller 60 and the second radiator 50 is disposed at one side, for example, the left side, of the all-terrain vehicle 100, so that the space at the left side of the all-terrain vehicle 100 can be reasonably utilized, the overall space of the all-terrain vehicle 100 can be reasonably arranged, and the pipeline can be conveniently repaired and replaced at the later stage only at one side.

Furthermore, a water pump 80 is arranged between the second radiator 50 and the controller 60, and the water pump 80 can provide power, so that a circulation loop formed by the second radiator 50, the controller 60 and the power motor 30 can be smoothly circulated.

Alternatively, as shown in fig. 1 and 2, an engine water inlet pipe 21 and an engine water outlet pipe 22 are connected between the first radiator 40 and the engine 20, and the engine water inlet pipe 21 and the engine water outlet pipe 22 are respectively connected to the left and right sides of the engine 20. The engine inlet pipe 21 and the engine outlet pipe 22 may be disposed on two sides, so that the first radiator 40 and the engine 20 are slightly modified, and basically the connecting arrangement of the engine and the radiator of the conventional vehicle is adopted, thereby being beneficial to the overall design of the all-terrain vehicle 100.

Wherein, the liquid outlet 42 of the first heat sink 40 is higher than the liquid inlet 41. That is, the connection point of the first radiator 40 and the engine water inlet pipe 21 is higher than the connection point of the first radiator 40 and the engine water outlet pipe 22, so that the liquid inlet and outlet of the engine 20 can be facilitated, and the circulation of the cooling liquid is facilitated.

As shown in FIG. 2, the engine 20 comprises a cylinder head 23, the cylinder head 23 faces to the upper rear part, and the rear part of an engine water inlet pipe 21 bypasses a power motor 30 from the lower part and is connected with the cylinder head 23. That is to say, the engine water inlet pipe 21 can bypass the power motor 30 and then be connected with the cylinder head 23, so that the engine water inlet pipe 21 can avoid the power motor 30 and the engine water inlet pipe 21 can be ensured to be fixed and reliable.

Optionally, as shown in fig. 1, atv 100 further comprises: the water tank 70, the first radiator 40, and the second radiator 50 are all in communication with the water tank 70. The water tank 70 serves to supply water, and after the water amount in the first radiator 40 and the second radiator 50 is reduced to a certain extent, the water tank 70 replenishes water to the inside thereof, so that the normal heat dissipation of the engine 20 and the power motor 30 can be ensured.
