[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation modes of the present invention.

[0035] like Figures 1 to 4 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a body cover 12, a travel assembly 13, a power assembly 14, a power battery 15, a transmission assembly 16, a seat assembly 17 and a cargo box assembly 18. The frame 11 is used as the basic framework of the all-terrain vehicle 100 to carry the body cover 12, the travel assembly 13, the power assembly 14, the power battery 15, the transmission assembly 16, the seat assembly 17 and the cargo box assembly 18. Among them, the body cover 12 is at least partially arranged on the frame 11, and the body cover 12 and the frame 11 are connected to form a protective frame for protecting the internal parts of the all-terrain vehicle 100. The travel assembly 13 is at least partially arranged under the frame 11, and the travel assembly 13 includes a front wheel 131 and a rear wheel 132. The power assembly 14 is supported by the frame 11, and the power assembly 14 is connected to at least one of the front wheel 131 and the rear wheel 132 through the transmission assembly 16, so that the power assembly 14 can drive the all-terrain vehicle 100 to move. The power battery 15 is at least partially disposed on the frame 11, and the power battery 15 can also provide energy for the power assembly 14. The seat assembly 17 is at least partially disposed on the frame 11, and is used to provide support for the driver and the passenger. The cargo box assembly 18 is at least partially disposed on the rear side of the frame 11, and the cargo box assembly 18 is used to carry cargo on the all-terrain vehicle 100. Specifically, the frame 11 includes a rear frame 111 disposed at the rear of the frame 11, and the rear frame 111 is surrounded by a receiving space 1111, and the power assembly 14 is at least partially disposed in the receiving space 1111. In order to clearly illustrate the technical solution of the present invention, the following is also defined. Figure 1In the present application, the front-to-back direction of the all-terrain vehicle 100 refers to the length direction of the all-terrain vehicle 100, the left-to-right direction of the all-terrain vehicle 100 refers to the width direction of the all-terrain vehicle 100, and the up-down direction of the all-terrain vehicle 100 refers to the height direction of the all-terrain vehicle 100.

[0036] As an implementation method, the power assembly 14 includes a drive motor 141 and a range extender 142. The range extender 142 provides energy for the drive motor 141, and the drive motor 141 is used to drive the travel assembly 13. The power battery 15 is electrically connected to the range extender 142 so that the range extender 142 can charge the power battery 15; the power battery 15 is also electrically connected to the drive motor 141 so that the power battery 15 can provide energy for the drive motor 141.

[0037] like Figure 5 As shown, as an implementation, the all-terrain vehicle 100 further includes a suspension device 29, which is disposed between the power assembly 14 and the frame 11. When the power assembly 14 is an engine, the engine is connected to the frame 11 through the suspension device 29; when the power assembly 14 is a drive motor 141, the drive motor 141 is connected to the frame 11 through the suspension device 29; when the power assembly 14 is a combination of a range extender 142 and a drive motor 141, the suspension device 29 can be disposed between the range extender 142 and the frame 11, and the suspension device 29 can also be disposed between the drive motor 141 and the frame 11. Specifically, the suspension device 29 has a supporting and shock absorbing effect on the power assembly 14, and the suspension device 29 also has a limiting effect on the power assembly 14. The suspension device 29 can be used to support the power assembly 14 and reduce the transmission of vibration between the power assembly 14 and the frame 11. At the same time, the suspension device 29 can also limit the movement of the power assembly 14, which is beneficial to improving the stability performance between the power assembly 14 and the frame 11.

[0038] As an implementation method, the suspension device 29 includes a suspension assembly 291, and at least two or more suspension assemblies 291 constitute the suspension device 29. In the suspension device 29, the axis of the suspension assembly 291 extends along the width direction of the all-terrain vehicle. When the power assembly 14 is a combination of a range extender 142 and a drive motor 141, the minimum distance between the drive motor 141 and the range extender 142 is greater than 0, and the drive motor 141 and the range extender 142 are independently arranged. After the drive motor 141 and the range extender 142 are independently arranged, they can be easily maintained and maintained separately. At the same time, different drive motors 141 and range extenders 142 can be selected for use according to actual needs. The front end of the drive motor 141 is connected to the frame 11 through at least one suspension assembly 291, the rear end of the drive motor 141 is connected to the frame 11 through at least one suspension assembly 291, the front end of the range extender 142 is connected to the frame 11 through at least one suspension assembly 291, and the rear end of the range extender 142 is connected to the frame 11 through at least one suspension assembly 291. Through the above arrangement, when the drive motor 141 and the range extender 142 are started or working, the suspension assembly 291 can reduce the vibration transmission between the drive motor 141 and the frame 11, and can reduce the vibration transmission between the range extender 142 and the frame 11, which is conducive to improving the comfort of the all-terrain vehicle 100. In addition, the number of suspension assemblies 291 can be increased and set according to different usage scenarios and actual conditions to reduce the vibration transmission between the power assembly 14 and the frame 11 and improve the comfort of the all-terrain vehicle 100. Further, the front end of the drive motor 141 is connected to the frame 11 through two suspension components 291, and the rear end of the drive component 141291 is connected to the frame through one suspension component 291. The three suspension components 291 on the drive motor 141 can form a stable triangular structure, thereby enhancing the connection stability between the drive motor 141 and the frame 11. Similarly, the front end of the range extender 142 is connected to the frame 11 through two suspension components 291, and the rear end of the range extender 142 is connected to the frame 11 through one suspension component 291. The three suspension components 291 on the range extender 142 can also form a stable triangular structure, thereby correspondingly enhancing the connection stability between the range extender 142 and the frame 11.

[0039] like Figure 6As shown, as an implementation, the suspension assembly 291 includes a base 2911 and a suspension bushing 2912, one end of the base 2911 is provided with a connection portion 2911a connected to the drive motor 141 or the range extender 142, the other end of the base 2911 is provided with a mounting hole 2911b, the suspension bushing 2912 is arranged in the mounting hole 2911b, and the suspension bushing 2912 is also connected to the frame 11 through a fastener 2913 extending in the width direction of the all-terrain vehicle 100. Specifically, the suspension bushing 2912 and the mounting hole 2911b are coaxially arranged. The suspension assembly 291 can be fixedly connected to the drive motor 141 or the range extender 142 through the connection portion 2911a on the base 2911 and fixing devices such as bolts, and the suspension assembly 291 can be fixedly connected to the frame 11 through the mounting hole 2911b on the base 2911, the suspension bushing 2912 and fixing devices such as bolts, that is, the drive motor 141 or the range extender 142 is fixedly connected to the frame 11 through the base 2911 and the suspension bushing 2912. Through the above arrangement, the connection stability between the frame 11 and the drive motor 141, and between the frame 11 and the range extender 142 can be improved.

[0040] As an implementation, the suspension assembly 291 further includes an anti-collision pad 2913, which is disposed on both sides of the suspension bushing 2912 or both sides of the mounting hole 2911b, and the anti-collision pad 2913 can buffer the force between the suspension assembly 291 and the frame 11 in the width direction of the all-terrain vehicle 100. The anti-collision pad 2913 can be made of a material such as a rubber pad, thereby improving the buffering performance of the suspension assembly 291 and the frame 11, and thus increasing the service life of the suspension assembly 291.

[0041] Specifically, the suspension bushing 2912 includes an inner core 2912a, a buffer 2912b and an outer tube 2912c. The inner core 2912a, the buffer 2912b and the outer tube 2912c are coaxially arranged, the buffer 2912b is sleeved on the outer side of the inner core 2912a, and the outer tube 2912c is sleeved on the outer side of the buffer 2912b. The inner core 2912a and the buffer 2912b are fixedly connected, and the buffer 2912b and the outer tube 2912c are fixedly connected. The buffer 2912b can be made of a rubber block, so that the suspension bushing 2912 can have both buffering and supporting functions. In this embodiment, the inner core 2912a, the buffer 2912b and the outer tube 2912c can be assembled and vulcanized to improve the durability and structural strength of the three, which is conducive to improving the structural stability of the suspension assembly 291.

[0042] like Figure 7As shown, as an implementation method, a first plane passing through the axis of the outer tube 2912c and perpendicular to the length direction of the all-terrain vehicle 100 is defined, and a second plane passing through the axis of the outer tube 2912c and perpendicular to the height direction of the all-terrain vehicle 100 is defined. At least two first soft limit portions 2912d and at least two second soft limit portions 2912e are provided on the inner side of the outer tube 2912c, and the two first soft limit portions 2912d are symmetrically distributed about the first plane, and the two second soft limit portions 2912e are symmetrically distributed about the second plane. The first soft limit portion 2912d and the second soft limit portion 2912e are uniformly surrounded between the inner core 2912a and the outer tube 2912c and are arranged close to the inner wall of the outer tube 2912c, so that the first soft limit portion 2912d and the second soft limit portion 2912e can first buffer the strong vibration generated by the range extender 142 or the drive motor 141, thereby facilitating the improvement of the shock absorption effect of the suspension assembly 291.

[0043] As an implementation method, at least two hard limiters 2912f (such as Figure 6 As shown in FIG. 1 , the two hard stoppers 2912f are symmetrically distributed about the second plane. When the all-terrain vehicle 100 is traveling on a bad road, the road surface excitation causes the power assembly 14 to vibrate greatly in the height direction. The hard stoppers 2912f further support the drive motor 141 and the range extender 142, thereby improving the stability of the drive motor 141 and the range extender 142, and further improving the connection stability of the power assembly 14.

[0044] As an implementation method, the buffer 2912b includes a hard stop portion 2912g, which abuts against the inner wall of the outer tube 2912c and the outer wall of the inner core 2912a, and the hard stop portion 2912g is used to support the outer tube 2912c and the inner core 2912a. In the case where the drive motor 141 or the range extender 142 generates a large vibration, the hard stop portion 2912g can improve the support performance of the buffer 2912b, so that the outer tube 2912c and the inner core 2912a will not be greatly deformed, thereby improving the connection stability of the outer tube 2912c and the inner core 2912a.

[0045] As an implementation method, the size of the inner core 2912a in the length direction of the all-terrain vehicle 100 is greater than or equal to the size of the inner core 2912a in the height direction, and the size of the hard stop portion 2912g in the length direction of the all-terrain vehicle 100 is less than or equal to the size of the hard stop portion 2912g in the height direction. The size of the inner core 2912a in the height direction is smaller, which can make the buffer 2912b between the inner core 2912a and the outer tube 2912c have a larger size in the height direction, which can further enhance the support and shock absorption performance of the buffer 2912b in the height direction. Specifically, the hard stop portion 2912g in the buffer 2912b has a larger size in the height direction, which can increase the proportion of the hard stop portion 2912g in the height direction of the buffer 2912b, and can give the buffer 2912b better support and shock absorption performance in the height direction.

[0046] As an implementation, the buffer 2912b includes a first linear segment 2912j distributed along the length direction of the all-terrain vehicle 100 and a second linear segment 2912k distributed along the height direction. The first linear segment 2912j is a partial cavity structure distributed along the length direction of the all-terrain vehicle 100 in the buffer 2912b, and the second linear segment 2912k is a partial cavity structure distributed along the height direction in the buffer 2912b. The first linear segment 2912j and the second linear segment 2912k can reduce vibration transmission, increase the vibration isolation rate of the suspension component, and improve the comfort of the whole all-terrain vehicle. In the radial direction of the inner core 2912a, the size L8 of the first linear segment 2912j is greater than or equal to 2 mm and less than or equal to 4 mm, and the size L9 of the second linear segment 2912k is greater than or equal to 1.75 mm and less than or equal to 3.25 mm. The linear segment in the buffer 2912b can provide a better shock-absorbing effect, but its ability to provide a supporting effect is relatively poor. Setting the second linear segment 2912k to have a relatively smaller size can increase the distribution ratio of the hard limit portion 2912g in the height direction where the second linear segment 2912k is located, and the buffer 2912b can further have better supporting performance and shock-absorbing performance in the height direction.

[0047] like Figure 8 , Fig. 9 and Fig.10As shown, as an implementation, the all-terrain vehicle 100 further includes a suspension assembly 31, and the front wheel 131 and the rear wheel 132 are both connected to the frame 11 through the suspension assembly 31. The frame 11 includes a rocker support frame 116, and the rocker support frame 116 can provide a corresponding connection position for the rocker. The suspension assembly 31 includes a suspension rod 311 and a universal joint 312, one end of the suspension rod 311 is connected to the rocker support frame 116, and the other end of the suspension rod 311 is connected to the universal joint 312. Among them, the rocker support frame 116 includes a support frame body 1161 and a rod connecting seat 1162, the rod connecting seat 1162 is fixedly connected to the support frame body 1161, and one end of the suspension rod 311 is connected to the rod connecting seat 1162. Specifically, the tie rod connection seat 1162 includes a first connection plate 1162a, a second connection plate 1162b and a third connection plate 1162c, a portion of the third connection plate 1162c is connected to the first connection plate 1162a, and another portion of the third connection plate 1162c is connected to the second connection plate 1162b; a portion of the first connection plate 1162a is connected to the support frame body 1161, a portion of the second connection plate 1162b is connected to the support frame body 1161, and a portion of the third connection plate 1162c is connected to the support frame body 1161. Through the above arrangement, the connection stability between the first connection plate 1162a, the second connection plate 1162b and the third connection plate 1162c can be improved, and the connection stability between the support frame body 1161 and the tie rod connection seat 1162 can be improved. Specifically, the connection method in the above arrangement can adopt a connection method such as welding to enhance the anti-deformation ability of the tie rod connection seat 1162.

[0048] As an implementation, the first connecting plate 1162a includes a first connecting portion 1162d, the second connecting plate 1162b includes a third connecting portion 1162e, and the third connecting plate 1162c includes a fifth connecting portion 1162f and a sixth connecting portion 1162g, the fifth connecting portion 1162f is connected to the first connecting portion 1162d, and the sixth connecting portion 1162g is connected to the third connecting portion 1162e. The first connecting portion 1162d and the fifth connecting portion 1162f are fixedly connected by welding or other connection methods. The above arrangement is conducive to improving the connection stability of the first connecting portion 1162d and the fifth connecting portion 1162f, the third connecting portion 1162e and the sixth connecting portion 1162g, and thus improving the connection stability of the pull rod connecting seat 1162.

[0049] The first connecting plate 1162a further includes a second connecting portion 1162h, the second connecting plate 1162b further includes a fourth connecting portion 1162j, the third connecting plate 1162c further includes a seventh connecting portion 1162k, and the fifth connecting portion 1162f, the seventh connecting portion 1162k and the sixth connecting portion 1162g are arranged in a U shape, that is, the third connecting plate 1162c is basically in a U-shaped structure. In this embodiment, the second connecting portion 1162h is connected to the support frame body 1161, the fourth connecting portion 1162j is connected to the support frame body 1161, and the sixth connecting portion 1162g is connected to the support frame body 1161. Specifically, the second connecting portion 1162h, the fourth connecting portion 1162j and the seventh connecting portion 1162k are basically in a U-shaped structure and the three are arranged around the surface of the support frame body 1161, which is conducive to improving the connection stability between the support frame body 1161 and the pull rod connecting seat 1162.

[0050] As an implementation method, the ratio of the area of ​​the second connection portion 1162h to the area of ​​the first connection plate 1162a is greater than or equal to 0.35 and less than or equal to 0.65, the ratio of the area of ​​the fourth connection portion 1162j to the area of ​​the second connection plate 1162b is greater than or equal to 0.35 and less than or equal to 0.65, and the ratio of the area of ​​the seventh connection portion 1162k to the area of ​​the third connection plate 1162c is greater than or equal to 0.2 and less than or equal to 0.4. The above arrangement can increase the contact area between the first connection plate 1162a, the second connection plate 1162b and the third connection plate 1162c and the support frame body 1161, respectively, and improve the fixing strength between the rod connection seat 1162 and the support frame body 1161. At the same time, it is avoided that the second connection portion 1162h, the fourth connection portion 1162j and the seventh connection portion 1162k are too large, so as to avoid occupying the setting space of the suspension rod 311 in the rod connection seat 1162.

[0051] As an implementation, the third connecting plate 1162c further includes a first guide portion 1162m connected to the fifth connecting portion 1162f and a second guide portion 1162n connected to the sixth connecting portion 1162g, the first guide portion 1162m being tilted toward the direction close to the first connecting plate 1162a, and the second guide portion 1162n being tilted toward the direction close to the second connecting plate 1162b. Specifically, the first guide portion 1162m and the second guide portion 1162n are used to guide during the installation of the suspension rod 311, thereby improving the convenience of assembling the suspension rod 311 and the rod connecting seat 1162.

[0052] As an implementation method, the support frame body 1161 includes a left support tube 1161a and a right support tube 1161b. The left support tube 1161a is provided with two tie rod connection seats 1162 distributed in the vertical direction, and the right support tube 1161b is provided with two tie rod connection seats 1162 distributed in the vertical direction.

The first water tank 255 is arranged on the side close to the range extender 142, and the second water tank 257 is arranged on the side close to the drive motor 141, so that the arrangement of the first cooling pipeline 254 and the arrangement of the second cooling pipeline 256 will not interfere with each other.

[0065] Furthermore, along the width direction of the ATV 100, the first cooling pipeline 254 and the second cooling pipeline 256 are at least partially arranged on both sides of the power battery 15.

The air outlet body 2471 needs to place a beverage bottle or beverage can. When the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is too small, the beverage bottle or beverage can is easy to escape from the air outlet body 2471 during the driving of the all-terrain vehicle 100, affecting the driving safety of the all-terrain vehicle 100. When the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is too large, the air outlet direction of the air outlet mechanism 247 is affected, and it is easy to fail to deliver cold air or warm air to the driver and passengers in time. Further, the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is greater than or equal to 9.5° and less than or equal to 18°. Furthermore, the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is greater than or equal to 11° and less than or equal to 16°.

The diameter R of the accommodating space 2471a is within the above range, which can meet the requirements of placing most beverage bottles and beverage cans on the market in the accommodating space 2471a. At the same time, it can also avoid unreasonable occupation of the space inside the vehicle when the diameter R of the accommodating space 2471a is too large. Further, the diameter R of the accommodating space 2471a is greater than or equal to 50 mm and less than or equal to 80 mm.

The arrangement of the hollow partition 2473 can avoid blocking the air outlet mechanism 247 from delivering cold air and warm air, and can also provide support for the beverage placed in the air outlet body 2471. The hollow partition 2473 includes a hollow portion 2473a, which defines a projection plane perpendicular to the axis of the air outlet body 2471, the hollow partition 2473 has a partition projection on the projection plane, the hollow portion 2473a has a hollow portion 2473a projection on the projection plane, and the ratio of the area of ​​the hollow projection to the area of ​​the partition projection is greater than or equal to 0.05 and less than or equal to 0.35. The hollow partition 2473 needs to meet the ventilation requirements and avoid the reduction of ventilation volume, and at the same time, it also needs to provide support for the beverage placed in the air outlet body 2471. When the hollow portion 2473a is too large, the carrying capacity of the hollow partition 2473 is reduced, and there may be a problem that the hollow partition 2473 is not enough to carry the beverage. Similarly, when the hollow portion 2473a is too small, the hollow partition 2473 will affect the ventilation volume of the air outlet body 2471 and reduce the cooling or heating effect.

More specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface can also be 0.23. Through the above-mentioned arrangement, it is possible to prevent the area of ​​the first projection surface from being too large, which is not conducive to the arrangement of the frame 11 at the first composite part 1221, thereby avoiding the insufficient strength of the frame 11 and reducing the overall structural strength of the all-terrain vehicle 100; it is also possible to prevent the area of ​​the first projection surface from being too large, which may cause interference between the first composite part 1221 and other components of the all-terrain vehicle 100, thereby facilitating the improvement of the space utilization rate of the all-terrain vehicle 100; it is also possible to prevent the area of ​​the first projection surface from being too small, which may reduce the heat insulation and sound insulation effect of the first composite part 1221 on the power assembly 14, thereby meeting the arrangement requirements of the frame 11 and the structural strength requirements of the all-terrain vehicle 100, and the heat generated by the power assembly 14 can be isolated by the first composite part 1221, and the noise generated when the power assembly 14 is working can be reduced. At the same time, the arrangement of sound insulation cotton, heat insulation parts, etc. can be reduced, thereby reducing the weight of additional parts of the all-terrain vehicle 100, which is conducive to the lightweighting of the all-terrain vehicle 100. In addition, the first composite member 1221 can also reduce the vibration transmitted from the power assembly 14 to the seat assembly 17 , thereby improving the riding comfort of the all-terrain vehicle 100 .

Specifically, the ratio of the area of ​​the third projection plane to the area of ​​the fourth projection plane is greater than or equal to 0.24 and less than or equal to 0.33. More specifically, the ratio of the area of ​​the third projection plane to the area of ​​the fourth projection plane can also be 0.28. Through the above arrangement, it is possible to prevent the area of ​​the third projection plane from being too large to affect the overall structural strength of the vehicle door 27, and it is also possible to prevent the area of ​​the third projection plane from being too small to reduce the impact of the second composite component 1222 on the cockpit 26 (refer to Figure 2 ) has good heat insulation and sound insulation effects, so that the second composite part 1222 can isolate the heat outside the all-terrain vehicle 100 and reduce the noise transmitted from the outside of the all-terrain vehicle 100 to the inside of the cockpit 26 while meeting the structural strength requirements of the door 27, and at the same time can also reduce the weight of the door 27, which is conducive to the lightweight of the all-terrain vehicle 100.

Specifically, the ratio of the area of ​​the fifth projection surface to the area of ​​the sixth projection surface is greater than or equal to 0.32 and less than or equal to 0.45. More specifically, the ratio of the area of ​​the fifth projection surface to the area of ​​the sixth projection surface can also be 0.39. Through the above-mentioned arrangement, it is possible to prevent the area of ​​the fifth projection surface from being too large and affecting the overall structural strength of the control panel 123, and to prevent the area of ​​the fifth projection surface from being too small and reducing the heat insulation and sound insulation effects of the third composite component 1223 on the control panel. As a result, the third composite component 1223 can isolate the heat and noise transmitted from the front side of the all-terrain vehicle 100 to the cockpit 26 while meeting the structural strength requirements of the control panel 123, and at the same time can reduce the weight of the control panel 123, which is conducive to the lightweighting of the all-terrain vehicle 100.

[0078] As an implementation, the composite plate 122 also includes a fourth composite part 1224 disposed on the cargo box assembly 18.

Specifically, the ratio of the area of ​​the ninth projection plane to the area of ​​the tenth projection plane is greater than or equal to 0.8 and less than or equal to 1.09. More specifically, the ratio of the area of ​​the ninth projection plane to the area of ​​the tenth projection plane can also be 0.94. Through the above arrangement, it is possible to prevent the area of ​​the ninth projection surface from being too large to reduce the layout space of the power battery 15 and the parts around the power battery 15, and it is also possible to prevent the area of ​​the ninth projection surface from being too small to reduce the heat insulation effect of the fifth composite member 1225 and the sixth composite member 1226 on the power battery 15, so that the fifth composite member 1225 and the sixth composite member 1226 can improve the heat insulation capacity of the power battery 15 while meeting the layout requirements of the power battery 15 and the parts around the power battery 15, and are conducive to improving the shock absorption and buffering effect on the power battery 15. In addition, the sixth composite member 1226 can also serve as the shell of the power battery 15, so as to maintain the stable operation of the power battery 15, thereby improving the working efficiency and conversion efficiency of the power battery 15, and further improving the endurance of the all-terrain vehicle 100.

[0080] As an implementation method, the composite panel 122 is configured as a plate-like structure with a honeycomb structure, so that the composite panel 122 can absorb noise and vibration while isolating heat, thereby achieving the heat insulation and sound insulation functions of the composite panel 122.

[0081] In this embodiment, the composite panel 122 is configured as a double-layer structure, thereby improving the heat insulation and sound insulation effects of the composite panel 122. Specifically, the composite panel 122 is at least partially disposed around the ATV 100, thereby isolating the heat inside and outside the ATV 100, thereby improving the cooling and heating effects of the air conditioning assembly 24, and further improving the comfort of the ATV 100.

[0082] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
