An all-terrain vehicle 100, which may be a hybrid all-terrain vehicle, according to an embodiment of the invention is described below with reference to fig. 1-6.

As shown in fig. 1-6, an all-terrain vehicle 100 according to an embodiment of the invention includes: the all-terrain vehicle comprises a frame 10, a driving motor 20, a differential 22, wheels 23 and an air duct member 30, wherein the frame 10 comprises a frame 101, the driving motor 20 and the air duct member 30 are both arranged on the frame 101, the driving motor 20 can be used for driving the all-terrain vehicle 100 to move, specifically, the differential 22 and the driving motor 20 can be in transmission connection, and then the wheels 23 and the differential 22 are in transmission connection through a driving half shaft 24, wherein the number of the wheels 23 can be two, the two wheels 23 can be respectively located at two ends of the differential 22, the power of the driving motor 20 can be transmitted to the differential 22, and the differential 22 can selectively distribute the power to the wheels 23 at two ends of the differential 22 according to different requirements of the all-terrain vehicle 100 under different road conditions, so that the wheels 23 can rotate, and the driving motor 20 can stably and reliably drive the all-terrain vehicle 100. The wheels 23 may be front wheels, the all-terrain vehicle 100 may be a front-drive vehicle at this time, the wheels 23 may also be rear wheels, and the all-terrain vehicle 100 may be a rear-drive vehicle at this time.

As shown in fig. 1, the air duct member 30 is also disposed on the chassis 101, so as to ensure the stability and reliability of the installation of the air duct member 30 on the all-terrain vehicle 100. Further, the air duct member 30 may form an air passage 33 together with the vehicle body frame 101, the air passage 33 has an air inlet 31 and an air outlet 32, the air inlet 31 is disposed to be open to the outside of the vehicle body frame 10, and the air outlet 32 is disposed to be open to the driving motor 20, so that the wind blows toward the driving motor 20. Specifically, an air inlet is formed at the outer side of the all-terrain vehicle 100, when the all-terrain vehicle 100 is in normal driving, air at the outer side of the all-terrain vehicle 100 can be blown to the air inlet 31 of the air duct member 30 from the air inlet 31, the air flows into the air duct member 30 through the air inlet 31, and flows out to the driving motor 20 from the air outlet 32 of the air duct member 30, because the driving motor 20 can generate heat during normal operation, and the surface temperature is high, so that the air blown out to the driving motor 20 from the air outlet 32 of the air duct member 30 can play a role in cooling and heat dissipation on the driving motor 20, by such arrangement, not only can the outer side of the all-terrain vehicle 100 be fully utilized to dissipate heat of the driving motor 20 during driving, but also the energy consumption of the all-terrain vehicle 100 cannot be increased due to heat dissipation on the driving motor 20, so that a separate radiator for the driving motor 20 is not needed, and the flow of flowing cooling liquid in the driving motor 20 can be omitted, and the air duct member 30 has a simple structure and can be conveniently manufactured. In addition, the air duct 30 with a relatively simple structure can also make the distance of the wind short, and the speed is high, which can improve the heat dissipation efficiency of the driving motor 20.

Therefore, the air inlet 31 of the air duct piece 30 is arranged in a manner of being opened towards the outer side of the frame 10, and the air outlet 32 of the air duct piece 30 is arranged in a manner of being opened towards the driving motor 20, so that wind enters the air duct piece 30 from the outer side of the all-terrain vehicle 100 through the air inlet 31 in the driving process of the all-terrain vehicle 100, and then blows the wind to the driving motor 20 through the air outlet 32 of the air duct piece 30 to dissipate heat for the driving motor 20, therefore, the effect of dissipating heat for the driving motor 20 can be ensured, the wind at the outer side of the all-terrain vehicle 100 can be fully utilized. In addition, the air duct member 30 itself has a simple structure, and can be conveniently manufactured.

Specifically, the cockpit bottom plate 34 and the cockpit front plate 35 are disposed on the vehicle chassis 101, and the cockpit bottom plate 34 is disposed longitudinally behind the cockpit front plate 35, so that the cockpit front plate 35, the cockpit bottom plate 34 and the vehicle chassis 101 together define the longitudinal air channel 33, wherein the cockpit front plate 35 is disposed to be open towards the longitudinal front, which may cause the air inlet 31 of the air channel 33 to face the longitudinal front of the vehicle frame 10, and thus, when the all-terrain vehicle 100 travels forwards normally, air around the all-terrain vehicle 100 will move backwards due to the principle of relative movement, so that wind may rapidly enter the air channel 33 through the air inlet 31, thereby further increasing the speed of air flowing in the air channel 33, and further increasing the heat dissipation efficiency of the driving motor 20.

As shown in fig. 4 to 6, a seat 12 is disposed in the cockpit 11, an installation space 121 is formed below the seat 12, the driving motor 20 is disposed in the installation space 121, and the air outlet 32 is communicated with the installation space 121. Specifically, the seat 12 needs to be raised relative to the bottom of the frame 10 and has a certain height to facilitate the riding of a driver and a passenger, and to facilitate the driving operation of the atv 100 by the driver, the raised seat 12 is hollow, so that the mounting space 121 is formed below the seat 12, the driving motor 20 is disposed in the mounting space 121, which not only ensures the stability of the mounting of the driving motor 20 on the atv 100, but also enables the driving motor 20 to fully utilize the space below the seat 12, thereby preventing the space below the seat 12 from being idle, improving the space utilization rate of the atv 100, and further making the structure of the atv 100 more compact. In addition, the seat 12 can also protect the driving motor 20, so that the driving motor 20 can be prevented from being damaged by erosion of external foreign objects and impact of external force to a certain extent, and the service life of the driving motor 20 can be prolonged.

Referring to fig. 4 to 6, the air duct 30 is disposed in the cab 11, the air duct 30 is located at the front lower portion of the seat 12, and the air outlet 32 is communicated with the installation space 121. Specifically, the air duct member 30 is arranged in the cockpit 11, so that the air duct member 30 can make full use of available space in the cockpit 11, the structural layout of the all-terrain vehicle 100 can be prevented from being influenced by the arrangement of the air duct member 30, the all-terrain vehicle 100 can be conveniently produced, the air duct member 30 is positioned in the front lower part of the seat 12, the arrangement of the air duct member 30 can be prevented from influencing the riding of a driver and a passenger on the seat 12, and the use experience of a user can be improved. Further, the air outlet 32 of the air duct piece 30 is directly communicated with the installation space 121, so that air blown out from the air outlet 32 directly enters the installation space 121 to contact with the driving motor 20, the whole body of the air and the driving motor 20 can be ensured to be in contact, heat dissipation can be more uniform, and the heat dissipation effect of the air on the driving motor 20 can be improved.

Specifically, the driving motor 20, the motor controller 50 and the power battery 40 are distributed in the installation space 121 at intervals in the transverse direction, so that the driving motor 20, the motor controller 50 and the power battery 40 can make full use of the installation space 121 below the seat 12, the space utilization rate below the seat 12 can be improved, the weight of the installation space 121 in the transverse direction can be balanced, and the reliability of the all-terrain vehicle 100 can be further improved.

In addition, the seat 12 can protect the driving motor 20, the motor controller 50 and the power battery 40, and the driving motor 20, the motor controller 50 and the power battery 40 can be prevented from being damaged by external impact or erosion of external foreign objects, so that the service lives of the driving motor 20, the motor controller 50 and the power battery 40 can be prolonged, and the reliability of the all-terrain vehicle 100 can be further improved.

Further, by electrically connecting the motor controller 50 with the driving motor 20, electrically connecting the power battery 40 with the motor controller 50, and electrically connecting the power battery 40 with the driving motor 20, in this way, the motor controller 50 can control the on and off of the driving motor 20, the power battery 40 can supply power to the driving motor 20 to maintain the normal operation of the driving motor 20, the driving motor 20 can generate power when the atv 100 is in the corresponding working condition, and the current generated by the driving motor 20 can be input into the power battery 40 through the motor controller 50 to be stored, or can be directly input into the power battery 40 to be stored, so that the self-power generation of the atv 100 can be realized, and the energy consumption of the power battery 40 can be indirectly reduced. In addition, since the driving motor 20, the motor controller 50 and the power battery 40 are laterally spaced below the seat 12 and are relatively close to each other, the electrical connection between the driving motor 20, the motor controller 50 and the power battery 40 can be more stable and reliable.

Further, as shown in fig. 2 and 3, an engine 60 is disposed behind the driving motor 20, wherein the engine 60 may be used for driving the rear wheels, and the driving motor 20 may be used for driving the front wheels, so that the all-terrain vehicle 100 may selectively realize four-wheel drive according to the operating conditions. Of course, the positions of the motor 60 and the drive motor 20 may be interchanged.

As shown in fig. 4 and 6, a first floor 111, a second floor 112, and a third floor 113 located between the first floor 111 and the second floor 112 are further provided in the cab 11, and the top of the third floor 113 is higher than the first floor 111 and the second floor 112 to form a part of the air passage 33.

In addition, because the third floor 113 is located between the first floor 111 and the second floor 112, although the third floor 113 is higher than the first floor 111 and the second floor 112, the feet of the rider are respectively placed on the first floor 111 and the second floor 112, so that the feet of the rider are not affected by the third floor 113, and thus, the feet of the rider can be ensured to have sufficient activity space, and the use experience of the user can be improved.

In addition, the air duct 30 can separate the first floor 111 from the second floor 112, so that the relative independence of the moving areas of the feet of the driver and the passenger can be ensured, the feet of the passenger can be prevented from entering the area of the driver without attention, the driving of the all-terrain vehicle 100 by the driver is prevented from being influenced, and the safety of the user can be improved.

As shown in fig. 4 and fig. 6, the third floor 113 is detachably installed between the first floor 111 and the second floor 112, which not only facilitates installation and installation of the third floor 113 and simplifies production and manufacture of the all-terrain vehicle 100 to a certain extent, but also facilitates detachment of the third floor 113, so as to inspect and repair the inside of the air duct 30, and improve flexibility and reliability of the arrangement of the air duct 30.

As shown in fig. 4 and 5, the air passage 33 may mainly include: the air conditioner comprises a front section 331, a middle section 332 and a rear section 333, wherein the middle section 332 is positioned between the front section 331 and the rear section 333, the front section 331 is communicated with the air inlet 31, the rear section 333 is communicated with the air outlet 32, the cross-sectional area of the front section 331 is larger than that of the middle section 332, and/or the cross-sectional area of the rear section 333 is larger than that of the middle section 332. Specifically, the front section 331 is communicated with the air inlet 31, and the cross-sectional area of the front section 331 is larger than that of the middle section 332, so that the air inlet area can be enlarged in unit time, more air enters the air channel 33 from the air inlet 31, the cross-sectional area of the middle section 332 is set to be smaller, the flowing speed of the air in the air channel member 30 can be increased, and the speed of heat dissipation and circulation of the air to the driving motor 20 can be increased. Further, the cross-sectional area of the rear section 333 is larger than that of the middle section 332, so that the air flowing out of the rear section 333 can form a surrounding heat dissipation effect on the driving motor 20, the heat dissipation efficiency of the driving motor 20 can be improved, and the reliability of the air duct piece 30 can be improved.

As shown in fig. 4 to 6, the front deck 35 forms a front section 331 together with the vehicle body frame 101, and the front deck 35 is configured as a sloping deck structure sloping obliquely downward from front to rear in the front-rear direction of the vehicle body frame 10. Specifically, when wind enters the air channel 33 from the outside of the all-terrain vehicle 100, the wind needs to pass through the front section 331 of the air channel 33 first, the cab front plate 35 is constructed into an inclined plate structure which is obliquely and downwardly arranged from the front to the back along the front-back direction of the frame 10, the guiding effect on the wind flowing can be achieved, the wind flowing is smoother, the noise generated when the wind enters the air channel 33 from the air inlet 31 can be reduced, and the reliability of the wind channel piece 30 can be further improved.

As shown in fig. 4 to fig. 6, the cockpit bottom plate 34 may mainly include a first section bottom plate 341 and a second section bottom plate 342 connected behind the first section bottom plate 341, and the second section bottom plate 342 is higher than the first section bottom plate 341, the first section bottom plate 341 and the chassis 101 form a middle section 332 of the air channel 33, and the second section bottom plate 342 and the chassis 101 form a rear section 333, so that connectivity between the middle section 332 and the rear section 333 of the air channel 33 can be ensured, and wind in the air channel 33 can directly flow to the rear section 333 through the middle section 332 of the air channel 33, so that a speed of the wind flowing in the air channel 33 is increased, and loss of the wind can be reduced. In addition, the second section of bottom plate 342 is higher than the first section of bottom plate 341, so as to increase the height of the air outlet 32, thereby increasing the diffusion range of the air flowing out from the air outlet 32, and further ensuring the heat dissipation effect of the air flowing out from the air channel 33 on the driving motor 20.

As shown in fig. 4-6, the second section of bottom plate 342 may mainly include: a top wall 3421 and a side wall 3422, the side wall 3422 is vertically disposed and connected between the top wall 3421 and the first stage floor 341, and the top wall 3421 is higher than the first stage floor 3421 and higher than the top of the driving motor 20. Specifically, the top wall 3421 is higher than the first-stage bottom plate 341 and higher than the top of the driving motor 20, and the side wall 3422 is vertically disposed between the top wall 3421 and the first-stage bottom plate 341, since the top wall 3421 of the second-stage bottom plate 342 is higher than the top wall 3421 of the air duct member 30, rather than the whole air duct member 30 is higher, the height of the air outlet 32 in the vertical direction can be increased, and the flow velocity of the air in the air passage 33 can be prevented from being affected on the premise of increasing the heat dissipation area of the air when the air flows out from the air passage 33. In addition, because of the riding habits of the occupant and the general posture of the occupant for putting his or her legs, the top wall 3421 of the second stage floor 342 is set high, and the second stage floor 342 will have no or little influence on the putting of the occupant's legs.

As shown in fig. 4 and 5, in the area corresponding to the top wall 3421, the distance between the two side walls 3422 increases in the front-to-rear direction, and the cross-sectional area of the air outlet 32 is larger than that of the driving motor 20. Specifically, the distance between the two side walls 3422 corresponding to the top wall 3421 is gradually increased from front to back, and the cross-sectional area of the air outlet 32 is made larger than the cross-sectional area of the driving motor 20, so that the air blown from the second bottom plate 342 and the two lateral sides of the driving motor 20 can form surrounding contact, the heat dissipation effect of the air blown from the second bottom plate 342 on the driving motor 20 can be improved, and the reliability of the air duct member 30 can be further improved.

Further, because in the direction of keeping away from seat 12, the range of driver and passenger's leg activity can increase gradually, so make the interval between two lateral walls 3422 set up to increase gradually the trend in the direction from the past backward, compare in directly set up the interval between two lateral walls 3422 wholly great, can be under the prerequisite of guaranteeing the radiating effect to driving motor 20, reduce the space that second section bottom plate 342 took first floor 111 and second floor 112, can reduce second section bottom plate 342 and carry out the influence that moves about to driver and passenger's leg, can promote user's use experience like this.

As shown in fig. 4 and 6, a cup groove 36 is disposed at the top wall 3421, and the bottom of the cup groove 36 is higher than the top of the first stage bottom plate 341. Specifically, since the top wall 3421 is higher than the top of the driving motor 20, in order to prevent the space from being left unused from the top wall 3421 to the top of the driving motor 20, the cup groove 36 may be formed at the top wall 3421, the cup groove 36 may be used for placing a cup or other objects, and by setting the bottom of the cup groove 36 higher than the top of the first section bottom plate 341, the setting of the cup groove 36 may be prevented from affecting the setting of the driving motor 20, and the driving motor 20 with a high temperature may be prevented from contacting the cup groove 36 to burn the cup groove 36, so that the structural stability of the cup groove 36 may be improved. In addition, the bottom of the cup groove 36 is higher than the top of the first section of the bottom plate 341, so that the cup groove 36 can be prevented from blocking the wind blowing from the front side of the driving motor 20, thereby affecting the heat dissipation of the driving motor 20, and further ensuring the heat dissipation effect of the driving motor 20. Wherein, the cup groove 36 can be a plurality of, for example: cup slots 36 may be three.
