DESCRIPTION OF EMBODIMENTS

In related art, all-terrain vehicles adopt a hybrid drive mode, and power units thereof are composed of a motor and an engine which assist each other in outputting power to achieve energy-saving effects, which greatly improves power performance of the vehicles. Due to the increase in power, a consequent heat management has also become a major problem. A hybrid vehicle is equipped with a power battery, where the power battery is greatly affected by temperature, and charging power and discharging power are lower at high and low temperatures. In order to maintain a good state of the power battery and control the temperature of the power battery to be within a certain range, a reasonable thermal management heat dissipation system is required to balance temperatures of a motor, an engine, the power battery, etc. For this reason, a head cooling system is typically mounted on a windward side of a front end of an all-terrain vehicle. However, layout designs of head cooling systems of all-terrain vehicles in the related art are relatively complicated, and heat dissipation effects of motors are poor. The inventor has found that the reason for this problem is that in an all-terrain vehicle in the related art, a head cooling system is often mounted on a windward side of a front end of the vehicle, where the head cooling system includes a liquid cooling radiator and superimposed components such as a motor radiator, an engine radiator, a fan, etc., where the liquid cooling radiator is configured to dissipate heat from a power battery, the engine radiator is configured to dissipate heat from an engine, and the motor radiator is configured to dissipate heat from a motor. As a result, a head space of the all-terrain vehicle is limited, leading to a relatively complex layout design of the head cooling system, and a distance between the motor and the motor radiator is relatively long, resulting in a relatively large loss of cooling capacity, which affects a heat dissipation effect of the motor.


For the above technical problems, a new all-terrain vehicle is provided in the embodiments of the present application, by arranging a motor heat dissipation assembly on a first transverse beam located at a middle of a frame, where the motor heat dissipation assembly is located on a rear side of the first transverse beam, that is, the motor heat dissipation assembly is arranged on a side of the middle of the frame away from a front end of the vehicle along a first direction (front and rear directions) of the all-terrain vehicle. Such an arrangement can free up a part of front space of the front end of the all-terrain vehicle, which can reduce the layout difficulty of a head cooling system and further optimize a layout of the whole vehicle.


Further, a distance between a motor and a motor radiator can be shortened to cause a path of a circulating pipeline between the motor and the motor radiator to become shorter, which avoids a loss of cold capacity, improves heat dissipation effects, and saves costs.


First of all, in order to facilitate descriptions of the embodiments in the present application, a coordinate system in the drawings is firstly explained, where an X-axis direction is defined as a first direction, which may be a driving direction of an all-terrain vehicle, i.e., front and rear directions; a Y-axis direction is defined as a second direction, which may be left and right directions of the all-terrain vehicle, i.e., the second direction is consistent with a width direction of the all-terrain vehicle, that is, the second direction is a width direction of a front frame; and a Z-axis direction is defined as a third direction, which may be defined as upper and lower directions of the all-terrain vehicle, i.e., the third direction is consistent with a height direction of the all-terrain vehicle, that is, the third direction is a height direction of the front frame.


As shown in FIGS. 1 to 4, an all-terrain vehicle provided in an embodiment of the present application may be a hybrid all-terrain vehicle, including a power battery, a motor 30 and an engine 40, where the power battery is configured to provide a driving current to the motor 30, and the motor 30 is a drive motor, and the motor 30 and the engine 40 assist each other in outputting power to achieve energy-saving effects, thereby greatly improving power performance of the vehicle. At the same time, as power increases, the heat generated increases, and a thermal management cooling system is required to balance temperatures of the motor 30, the engine 40, and the power battery.


The thermal management cooling system includes a head cooling system arranged at a front end of the all-terrain vehicle. The head cooling system includes a liquid cooling radiator, an engine radiator, and an motor radiator, where a frame 10 includes a front, a middle, and a rear along a first direction; where a first space 101 is formed between the front and the middle of the frame 10, and the first space 101 may be configured to be a cab; and a second space 102 is formed between the middle and the rear of the frame 10, and the second space 102 is used for arranging the motor 30, the engine 40, etc., i.e., the second space 102 is an equipment compartment instead of a usual rear passenger space, and a passenger and a driver seat in the cab.


The aforementioned liquid cooling radiator is usually arranged on a windward side of a front (front end) of the frame 10, where the liquid cooling radiator is configured to dissipate heat from the power battery; the engine radiator is also arranged in a front space of the front end, and the engine radiator is configured to dissipate heat from the engine 40. It should be noted that the liquid cooling radiator and the engine radiator are connected with a refrigeration component of the thermal management cooling system, and the refrigeration component includes but is not limited to a water cooling component, etc.

The motor heat dissipation assembly 20 is mounted on the first transverse beam 11 and is located on a side of the first transverse beam 11 facing the second space 102. The motor heat dissipation assembly 20 includes a first radiator 21 and a fan 22, where the first radiator 21 is mounted on the first transverse beam 11, and the fan 22 is connected to a side of the first radiator 21 facing the second space 102, i.e., the fan 22 is arranged opposite to the motor 30.


Further, the motor 30 includes a heat dissipation cavity, one end of the first radiator 21 is connected to an inlet of the heat dissipation cavity via a circulating pipeline, the other end of the first radiator 21 is connected to an outlet of the heat dissipation cavity via the circulating pipeline, and there is a cooling medium between the first radiator 21 and the heat dissipation cavity of the motor 30, where the cooling medium may be cooling water, and the cooling medium flows in the circulating pipeline.


The first space 101 has an air inlet 103 connected with the motor heat dissipation assembly 20, and during a driving process of the all-terrain vehicle, air flows to the motor heat dissipation assembly 20 via the air inlet 103, which may exchange heat with the cooling medium flowing through the first radiator 21, and the cooling medium may cool the motor 30 after heat exchange.


Compared with the solutions in the related art where a motor heat dissipation assembly is arranged in a front end, the motor heat dissipation assembly 20 is arranged in the middle of the frame 10 in the embodiment of the present application, which can free up a part of front space of the front end of the all-terrain vehicle, reduce the layout difficulty of the head cooling system of the all-terrain vehicle, and further optimize a layout of the whole vehicle. Further, a distance between the motor 30 and the motor heat dissipation assembly 20 can be shortened, to cause a path of the circulating pipeline between the motor 30 and the motor heat dissipation assembly 20 to be shorter, which avoids a loss of cold capacity, improves a heat dissipation effect, and saves costs.


On the basis of the aforementioned embodiments, the all-terrain vehicle further includes a driver seat and a passenger seat, where the driver seat and the passenger seat are arranged side by side in the first space 101 along the second direction, and an upper part of the driver seat and the passenger seat has a large gap along the second direction and is capable of forming the air inlet 103, i.e., the air inlet 103 is formed between the driver seat and the passenger seat.


Accordingly, the first transverse beam 11 is arranged at a rear side of the driver seat and the passenger seat, i.e., the motor heat dissipation assembly 20 is located at the rear side of the driver seat and the passenger seat along the first direction. Further, the motor heat dissipation assembly 20 may be opposite to the air inlet 103. For example, along the second direction, the motor heat dissipation assembly 20 is arranged between the driver seat and the passenger seat, and the first radiator 21 is directly opposite to the air inlet 103. Such an arrangement can prevent the driver seat and the passenger seat from blocking the motor heat dissipation assembly 20, increase a windward side of the motor heat dissipation assembly 20, and enhance a heat dissipation effect of the first radiator 21.


It should be understood that in some embodiments, the first space 101 is only provided with the driver seat, and the motor heat dissipation assembly 20 may be arranged on a side of the driver seat, that is, the air inlet 103 is formed on the side of the driver seat, which is not limited in the embodiments of the present application.


As shown in FIGS. 5 to 7, in the embodiment of the present application, the motor heat dissipation assembly 20 is obliquely arranged on the first transverse beam 11 along the first direction, and an inclined angle ranges from 30° to 60°.


Specifically, in the embodiment of the present application, the first radiator 21 is a rectangular plate structure in overall, which includes a first end and a second end which are oppositely arranged, where the first radiator 21 is arranged obliquely along the first direction, then the first end of the first radiator 21 may be arranged above the second end thereof. The first end of the first radiator 21 is connected to the first transverse beam 11, and a projection of the first end of the first radiator 21 on a first projection plane (a projection plane composed of the first direction and the second direction) is located in the second space 102.


The second end of the first radiator 21 extends obliquely and downward, and a projection of the second end of the first radiator 21 on the first projection plane is located in the first space 101, and an angle range between a connecting line of the first end and the second end of the first radiator 21 and the first projection plane may be 30° to 60°.


Preferably, the angle range between the connecting line of the first end and the second end of the first radiator 21 and the first projection plane may be 45°, i.e. an inclined angle of the first radiator 21 is 45°. Such an arrangement can optimize a layout of the first radiator 21, increase a windward area of the first radiator 21, and increase air flow efficiency, thereby improving a cooling effect of the motor 30.


Further, the second space 102 of the all-terrain vehicle is further provided with the engine 40 which is arranged above the motor 30 along the third direction, and the engine 40 is opposite to the air outlet of the motor heat dissipation assembly 20, i.e., the air outlet of the first radiator 21 is opposite to the engine 40.


With such arrangement, during a driving process of the all-terrain vehicle, air can enter the motor heat dissipation assembly 20 via the air inlet 103 between the driver seat and the passenger seat, and after the air exchange heat with the motor heat dissipation assembly 20, the cooling medium in the first radiator 21 dissipates heat and cools the motor 30, and then the air is blown to the engine 40 below by the fan 22, thereby dissipating heat from the engine 40, reducing heat concentration, and playing a heat dissipation role, thereby improving a cooling effect of the engine 40.


On the basis of the above embodiments, the frame 10 provided by the embodiment of the present application further includes a second transverse beam 12, a support frame 14, and a first support beam 13, where the second transverse beam 12 is arranged below the first transverse beam 11 along the third direction and maintains a certain interval.

At the same time, the first support beam 13 may be used for fixing the first radiator 21. It should be noted that the first support beam 13, the first transverse beam 11, and the second transverse beam 12 may be cylindrical steel tubes and the three are welded together to form a H-shape structure.


The support frame 14 may be a steel structure welded from a plurality of square steel tubes, which is a rectangular frame in overall and includes a first frame 141 and a second frame 142 arranged along the first direction and a third frame 143 and a fourth frame 144 arranged oppositely along the second direction, where the first frame 141 is connected to a rear of the frame 10, i.e., one end of the support frame 14 is connected to the rear of the frame 10, and the second frame 142 is arranged below the motor heat dissipation assembly 20 and is arranged close to the fan 22.


One end of the third frame 143 and one end of the fourth frame 144 are connected to the first frame 141, and the other ends are connected to the second frame 142. The third frame 143 and the fourth frame 144 are connected to the second transverse beam 12. The second transverse beam 12 is provided with two connecting seats spaced apart along the second direction, where tops of the connecting seats are connected to the third frame 143 and the fourth frame 144, thereby fixing the support frame 14. It should be noted that each connecting point of the support frame 14 is detachably connected by a fastener, etc.

For example, the first radiator 21 is detachably connected to the first transverse beam 11, the first support beam 13, and the support frame 14 by a fastener, which is not limited in the present embodiment.

For example, in the embodiment of the present application, the first radiator 21 is a rectangular plate structure in overall, the first radiator 21 is provided with four fixing frames 211, and the four fixing frames 211 are respectively defined as a first fixing frame, a second fixing frame, a third fixing frame, and a fourth fixing frame, where the first fixing frame and the second fixing frame are arranged on the top of the first radiator 21 along the third direction, and the first fixing frame and the second fixing frame are respectively located on two sides of the first radiator 21 along the second direction; i.e., the first fixing frame and the second fixing frame are respectively arranged at the first end of the first radiator 21, and the first fixing frame and the second fixing frame are arranged on left and right sides of the first end along the second direction.


The first fixing frame and the second fixing frame are configured to be connected to the first transverse beam 11. For example, the first transverse beam 11 is provided with at least two first fixing seats 111 spaced apart along the second direction, and the two first fixing seats 111 are arranged close to the first fixing frame and the second fixing frame, respectively. The first fixing frame and the second fixing frame are detachably connected to corresponding first fixing seats 111, for example, the first fixing frame and the second fixing frame are detachably connected to the first fixing seats 111 by fasteners.


Further, the third fixing frame and the fourth fixing frame are arranged at the bottom of the first radiator 21 along the third direction, and the third fixing frame and the fourth fixing frame are respectively located at the two sides of the first radiator 21 along the second direction, i.e., the third fixing frame and the fourth fixing frame are respectively arranged at the second end of the first radiator 21, and the third fixing frame and the fourth fixing frame are arranged at left and right sides of the second end along the second direction.


The third fixing frame and the fourth fixing frame are configured to be connected to the second transverse beam 12 and the first support beam 13, respectively. For example, the support frame 14 is provided with a first mounting frame 15, where the first mounting frame 15 is U-shaped in overall, the first mounting frame 15 extends along the third direction, one end of the first mounting frame 15 is connected to the third frame 143 of the support frame 14, i.e., an open end of the first mounting frame 15 is connected to two side walls of the third frame 143.


The other end of the first mounting frame 15 is connected to the third fixing frame of the first radiator 21, i.e., a closed end of the first mounting frame 15 is connected to the third fixing frame, and the closed end of the first mounting frame 15 is lower than the first transverse beam 11 to keep the bottom end of the first radiator 21 tilted.

Such an arrangement can facilitate replacement and maintenance of the motor 30 or the fan 22.


On the other hand, in the related art, an all-terrain vehicle generally includes a frame and a roll cage arranged on a top of the frame, where the frame is used for arranging a cab and mounting components such as an engine, etc., and the roll cage is a detachable steel tube assembly, which is often mounted on the top of the frame in the vehicle and plays a part in support, to protect safety of a driver and a passenger in the vehicle when the vehicle rolls over. However, in the related art, problems of the roll cage having poor structural strength and being prone to be deformed and broken may reduce safety of the vehicle. The inventors have found that a reason for these problems is that the roll cage in the related art is a detachable steel tube assembly, and no supporting structure is arranged between a side beam thereof and a frame, resulting in the roll cage's poor ability to resist lateral impacts and rolling impacts. Thus, when the vehicle rolls over, the roll cage is prone to be deformed and broken, affecting the safety of the vehicle.


For the aforementioned technical problems, an embodiment of the present application provides a new roll cage, by arranging a second support beam between a side beam and a middle of a frame, where the frame, the side beam, and the second support beam enclose a closed triangle structure.


Such an arrangement can enhance structural strength of the entire roll cage, thereby improving an ability of the roll cage to withstand lateral impacts and rolling impacts, reducing a risk of deformation and breakage of the roll cage, and improving the safety of the all-terrain vehicle.


As shown in FIGS. 8 to 10, the all-terrain vehicle provided in the embodiment of the present application includes a frame 90 and a roll cage 50, where the frame 90 is used for arranging a cab and mounting components such as an engine, the roll cage 50 is mounted on a top of the frame 90 along the third direction, and the roll cage 50 plays a supporting role to protect safety of a driver and a passenger in the vehicle when the vehicle rolls over.


Further, the roll cage 50 may be detachably mounted on the top of the frame 90, and the roll cage 50 is composed of a plurality of detachable tubes. For example, in the present embodiment, the roll cage is composed of a plurality of combined steel tube assemblies. Unless otherwise specified, a steel tube may be a round steel tube, which is not limited in the present application. The frame 90 includes a front, a middle, and a rear along a first direction, where a space between the front and the middle of the frame 90 is configured as a cab, and a space between the middle and the rear of the frame 90 may be used for mounting an engine.


As shown in FIG. 11, the front, the middle, and the rear of the frame 90 are respectively provided with first mounting points 710, second mounting points 720, and third mounting points 730 along the first direction. The roll cage 50 may be detachably connected to the front of the frame 90 via the first mounting points 710; the roll cage 50 may be detachably connected to the middle of the frame 90 via the second mounting points 720; and the roll cage 50 may be detachably connected to the rear of the frame 90 via the third mounting points 730.


It should be noted that the first mounting points 710 are arranged on left and right sides of the frame 90 along a second direction, the second mounting points 720 are arranged on the left and right sides of the frame 90 along the first direction, and the third mounting points 730 are arranged on the left and right sides of the frame 90 along the first direction, i.e., the roll cage 50 and the frame 90 are detachably connected via six mounting points, and the detachable connection method includes but is not limited to using fasteners such as plug-in bolts, etc.


Continuing to refer to FIGS. 8 to 10, the roll cage 50 provided in the embodiment of the present application includes a middle beam assembly 60, a support beam assembly, and two side beams 70, where, along the second direction, the middle beam assembly 60 is arranged in the middle of the entire roll cage 50, the two side beams 70 are respectively arranged on left and right sides of the middle beam assembly 60, the middle beam assembly 60 is connected to the side beams 70 on the two sides thereof, and the side beams 70 are connected to the frame 90, thereby connecting the roll cage 50 to the frame 90.


Specifically, the middle beam assembly 60 includes at least two third transverse beams 61, where the third transverse beams 61 may be round steel tubes, the at least two third transverse beams 61 are arranged spaced apart along the first direction, each of the third transverse beams 61 extends along the second direction, and two ends of the third transverse beams 61 are respectively connected to the side beams 70 on two sides thereof.


Further, the support beam assembly is used for connecting the side beams 70 and the frame 90 to enhance structural strength of the entire roll cage 50. The support beam assembly includes at least two second support beams 80, and one second support beam 80 is arranged close to a side beam 70 on each side, where one end of the second support beam 80 is connected to the middle of the frame 90, and the other end of the second support beam 80 extends toward the side beam 70 and is connected to the side beam 70, and the second support beam 80, the frame 90, and the side beam 70 jointly form a closed triangular structure.


It should be noted that, along the second direction, second support beams 80 are arranged between the frame 90 and the side beams 70 on the left and right sides, and closed triangular structures are respective enclosed, i.e., there are triangular structures between the frame 90 and the side beams 70 on the two sides thereof; where a triangle refers to a roughly triangular outline, including but not limited to a regular triangle.


Compared with solutions in the related art where no supporting structure is arranged between a side beam of a roll cage and a frame, which results in poor ability of the roll cage to resist lateral impacts and rolling impacts, in the embodiment of the present application, the second support beams 80 are arranged between the side beams 70 and the middle of the frame 90, and the frame 90, the side beams 70, and the second support beam, 80 enclose closed triangular structure.


Such an arrangement can enhance structural strength of the entire roll cage, thereby improving the ability of the roll cage 50 to withstand lateral impacts and rolling impacts, reducing a risk of deformation and breakage of the roll cage 50, and improving the safety of the all-terrain vehicle.


On the basis of the above embodiments, the middle beam assembly 60 further includes at least one fourth transverse beam 62, where the fourth transverse beam 62 is arranged between two adjacent third transverse beams 61 and extends along the first direction, and two ends of the fourth transverse beam 62 are respectively connected to the third transverse beams 61.


For example, the middle beam assembly 60 includes two third transverse beams 61 spaced apart, two fourth transverse beams 62 are arranged between the two third transverse beams 61, the two fourth transverse beams 62 are spaced apart along the second direction, and two ends of the fourth transverse beams 62 are respectively connected to the third transverse beams 61.


Preferably, the third transverse beams 61 and the fourth transverse beams 62 in the middle beam assembly 60 may be a one-piece structure. Such an arrangement can enhance structural strength of the middle beam assembly 60 and enhance an ability of the roll cage 50 to withstand lateral impacts and rollover impacts.


In order to realize detachable connections between the middle beam assembly 60 and the side beams 70 on the two sides thereof, in the embodiment of the present application, the side beams 70 extend along the first direction, and first mounting seats 74 are arranged on sides of the side beams 70 facing the third transverse beams 61, and the first mounting seats 74 may be welded to the side beams 70; i.e., along the second direction, the first mounting seats 74 are arranged at corresponding connection positions between the side beams 70 and the third transverse beams 61, and the first mounting seats 74 are located on inner sides of the side beams 70.


Accordingly, two ends of the third transverse beams 61 are respectively provided with second mounting seats 63 and are connected to the first mounting seats 74 via the second mounting seats 63, to cause the third transverse beams 61 to be detachably connected to the side beams 70. The first mounting seats 74 have first mounting surfaces, and, along the second direction, the first mounting surfaces are constructed as side surfaces of the first mounting seats 74 facing the second mounting seats 63; the second mounting seats 63 have second mounting surfaces, and, along the second direction, the second mounting surfaces are constructed as side surfaces of the second mounting seats 63 facing the first mounting seats 74, and the first mounting surfaces and the second mounting surfaces are arranged oppositely and fit together along the second direction.


With such arrangement, the first mounting seats 74 and the second mounting seats 63 are in surface contact along the second direction, and connection areas between the middle beam assembly 60 and the side beams 70 can be increased, thereby improving withstanding capacity. When the vehicle rolls over, a lateral impact force withstood by the roll cage 50 is perpendicular to the first mounting surfaces and the second mounting surfaces, which is conducive to transferring the lateral impact force and can reduce a risk of deformation of the roll cage 50.


Furthermore, a plurality of fasteners are arranged between the first mounting seats 74 and the second mounting seats 63, and the first mounting seat 74 and the second mounting seat 63 are detachably connected via the fasteners. A mounting direction of the fasteners is consistent with the second direction. For example, a fastener is configured to be a fastening bolt, and a mounting direction of the fastening bolt (also an axial direction of the fastening bolt) is consistent with the second direction. With such arrangement, the mounting direction of the fasteners is consistent with the second direction. In other words, the mounting direction of the fastener is consistent with a direction of a lateral impact force withstood by each mounting seat.


Compared with the related art where fasteners are mounted along the third direction, in the embodiment of the present application, the mounting direction of the fasteners is consistent with the second direction, which can lower a risk of withstanding, by the fasteners, a large shear force and causing deformation or breakage at the connection, and can improve connection reliability between the middle beam assembly 60 and the side beams 70, thereby improving safety of the vehicle.


On the basis of the above embodiments, in order to further improve the structural strength of the roll cage 50, the support beam assembly in the embodiment of the present application includes two second support beams 80, and the two second support beams 80 are respectively arranged on two sides of the middle of the frame 90 along the second direction.


Referring to FIG. 9, the two second support beams 80 are obliquely arranged between the middle of the frame 90 and the side beams 70 along the second direction, and the second support beams 80 includes first ends and second ends arranged oppositely, where the first ends of the second support beams 80 are connected to the frame 90, and the second ends of the second support beams 80 extend obliquely along the second direction toward sides of the side beams 70 and are connected to the side beams 70.


As shown in FIG. 10, the two second support beams 80 are symmetrically arranged along the first direction, the second support beams 80 are obliquely arranged along the first direction, and the first ends of the second support beams 80 are located on sides of the second ends thereof facing the rear of the frame 90. With such arrangement, the second support beams 80 are obliquely arranged, which can decompose a lateral impact force transferred thereto, to improve a withstanding capacity of the second support beams 80.


As shown in FIG. 11, in the embodiment of the present application, the two side beams 70 are symmetrically arranged on the two sides of the middle beam assembly 60 along the first direction, and the two side beams 70 are arranged in a splayed shape from the front to the rear of the frame 90. Further, a width between the two side beams 70 along the second direction gradually decreases from the front to the rear of the frame 90.


Further, each of the side beams 70 includes a first tubular column 71, a second tubular column 72, and at least one third tubular column 73, where the first tubular column 71 extends in overall along the second direction, one end of the first tubular column 71 is connected to a first mounting point 710 of the frame 90, and the other end thereof is connected to a third mounting point 730 of the frame 90, and a middle of the first tubular column 71 bulges upward along the third direction and is connected to the middle beam assembly 60, to cause the frame 90 and the middle beam assembly 60 to form a cab.


The second tubular column 72 is arranged outside the first tube column 71 along the second direction, one end of the second tubular column 72 is connected to the middle of the first tubular column 71, and the other end of the second tubular column 72 extends outward along the second direction and is connected to a second mounting point 720 of the frame 90. With such arrangement, when the vehicle rolls over, the second tubular column 72 can serve as a first force bearing point (in other words, the second tubular column 72 contacts the ground first), which can withstand most of the impact, thereby preventing the first tubular column 71 from withstanding relatively large impact, and improving the safety of the roll cage 50.


The third tubular column 73 is arranged between the first tubular column 71 and the second tubular column 72, the third tubular column 73 is arranged obliquely along the first direction, a top end of the third tubular column 73 is connected to the first tubular column 71, and a bottom end of the third tubular column 73 is connected to the second tubular column 72.


Further, in the embodiment of the present application, the first tubular column 71, the second tubular column 72, and the third tubular column 73 enclose a closed triangular structure. Such an arrangement is beneficial for transferring a lateral impact force and a longitudinal force withstood by the roll cage 50, thereby improving overall strength and stiffness of the roll cage 50.


On the basis of the above embodiments, each of the side beams 70 may include two third tubular columns 73, and the third tubular columns 73 may be symmetrically arranged on two sides of the second tubular column 72 along the first direction. Such an arrangement can improve structural strength of the side beam 70. Preferably, the side beam 70 includes one third tubular column 73, and the third tubular column 73 is arranged on a side of the second tubular column 72 facing the rear of the frame 90 along the first direction. Such an arrangement can improve the structural strength of the side beam 70 and increase a space of the cab at the same time.


For example, the third tubular column 73 is arranged obliquely along the first direction, and the top end of the third tubular column 73 is located on a side of a bottom end of the second tubular column 72 facing the rear of the frame 90, the top end of the third tubular column 73 is connected to the first tubular column 71, the bottom end of the third tubular column 73 is connected to the second tubular column 72, and the first tubular column 71, the second tubular column 72, and the third tubular column 73 enclose a closed triangular structure.


It should be noted that the first tubular column 71, the second tubular column 72, and the third tubular column 73 may be a one-piece structure to enhance the structural strength of the side beam 70. One end of the aforementioned second support beam 80 is connected to the middle of the frame 90, and the other end of the second support beam 80 may be connected to the second tubular column 72, for example, one end of the second support beam 80 is detachably connected to the frame 90, and the other end of the second support beam 80 is detachably connected to the second tube column 72. Such arrangement can facilitate mounting of the second support beam 80.


On the other hand, in the related art, an all-terrain vehicle includes a frame, where the frame is used for arranging a cab and mounting components or devices such as an engine. However, in the related art, in order to improve structural strength of the frame, a large number of transverse beams and connecting beams are arranged, which makes a layout of the frame too cramped, thereby affecting a mounting space of the frame and failing to meet a layout requirement of the whole vehicle. In particular, a layout of a front frame is too cramped, resulting in unreasonable arrangements of a balancing pole, a steering mechanism, and a front axle assembly of the all-terrain vehicle, which cannot meet the layout requirement of the whole vehicle and will also affect structural stability of the frame at the same time.


For the above technical problems, a frame and an all-terrain vehicle is provided in the embodiments of the present application, by arranging a fifth transverse beam between two first support longitudinal beams, two first vertical beam assemblies, the two first support longitudinal beams, and the fifth transverse beam enclose a first mounting space in a triangular shape. Such an arrangement reasonably optimizes a space between a first support frame and a second support frame, and divides the space between the first support frame and the second support frame into the first mounting space and a remaining space located above the first mounting space, thereby facilitating mounting of a balancing pole in the first mounting space, and mounting of other structures in the remaining space, which achieves advantages of reasonably optimizing a mounting space of the frame and improving strength and stiffness of the frame. In addition, another all-terrain vehicle is provided in an embodiment of the present application, by improving a structure of a front frame, where the front frame includes at least a first mounting space, a second mounting space, and a third mounting space, the first mounting space is located above the second mounting space along a third direction, the second mounting space and the third mounting space are arranged sequentially along a first direction, so that the first mounting space, the second mounting space, and the third mounting space form a structure similar to a triangle. Such an arrangement reasonably optimizes a mounting space of the front frame and improves strength and stiffness of the front frame, which improves structure stability of a frame.


Please refer to FIGS. 12 to 17, a frame includes a first support frame 10, a second support frame 110, and a first vertical beam assembly 120, where the first support frame 100 and the second support frame 110 are spaced apart along a third direction, and the second support frame 110 is located above the first support frame 100.


The first vertical beam assembly 120 is arranged between the first support frame 100 and the second support frame 110, and is used for connecting the first support frame 100 to the second support frame 110. A number of the first vertical beam assembly 120 may be one or two. When there are two first vertical beam assemblies 120, structural strength of the frame can be improved.


In the present embodiment, the first support frame 100 includes two first support longitudinal beams 1001 and a fifth transverse beam 1002. The two first support longitudinal beams 1001 are spaced apart along a second direction, i.e., the two first support longitudinal beams 1001 are spaced apart along a width direction of the frame. The first support longitudinal beam 1001 extends along a first direction, i.e., the first support longitudinal beam 1001 extends along a driving direction of the frame.


The fifth transverse beam 1002 is used for connecting the two first support longitudinal beams 1001, where the fifth transverse beam 1002 may be connected to middles of the two first support longitudinal beams 1001 to divide a space between the first support frame 100 and the second support frame 110 into front and rear parts, which is convenient for mounting of other components of the all-terrain vehicle.


In the present embodiment, each of the first support longitudinal beams 1001 is connected to the second support frame 110 via one first vertical beam assembly 120, i.e., there are two first vertical beam assemblies 120, and the two first vertical beam assemblies 120 are spaced apart along the second direction. In this way, structure strength of the frame can be improved.


Please refer to FIG. 14, the two first vertical beam assemblies 120, the two first support longitudinal beams 1001, and the fifth transverse beam 1002 enclose first mounting spaces in an triangular shape; and the first mounting space is used for mounting a balancing pole 170. For example, the balancing pole 170 includes a first balancing pole, and a second balancing pole and a third balancing pole connected to two ends of the first balancing pole.
