Description
Technical Field
[0001] This application relates to the technical field of all-terrain vehicles, and in particular, to an all-terrain vehicle. Background Art
[0002] As a vehicle with strong passing performance, all-terrain vehicles are increasingly favored by consumers.
[0003] All-terrain vehicles often operate in complex geographical environments, such as deserts, mountains, swamps, etc. These environments have extremely high requirements for vehicle performance. Especially under harsh conditions such as high temperature and heavy dust, the power system of all-terrain vehicles, including the engine and other key components, will generate a large amount of heat. If effective heat dissipation cannot be achieved, it will lead to a decline in equipment performance and even cause failures, seriously affecting the user experience and driving safety.
[0004] To solve the above technical problems, currently, a single heat dissipation module is usually arranged at the front end of the frame of the all-terrain vehicle to dissipate heat from the engine. Limited by the heat dissipation area and efficiency, the single heat dissipation module is difficult to meet the heat dissipation requirements of all-terrain vehicles under high-intensity and high-load working conditions. To solve the technical problem of low heat dissipation efficiency, usually two heat dissipation modules are set at the front end of the frame. Although the heat dissipation efficiency is improved, the heat dissipation modules are set at the front end of the frame and are easily affected by road dirt adhesion and bumps, that is, the degree of dirt and the risk of bumps are increased, the cleaning and / or maintenance requirements for the heat dissipation modules are increased, that is, the cleaning and maintenance costs of the heat dissipation modules are increased, and at the same time, the heat dissipation performance and service life of the heat dissipation modules are reduced. Summary of the Utility Model
[0005] To solve the deficiencies of the prior art, the purpose of this application is to provide an all-terrain vehicle with high heat dissipation efficiency and low maintenance requirements for heat dissipation modules.
[0006] To achieve the above purpose, this application adopts the following technical solutions:
[0007] An all-terrain vehicle, which includes a frame, a body cover, a seat assembly, a suspension assembly, a running assembly, a power system and a heat dissipation system. The frame is divided into a front region and a rear region along the length direction; the body cover is connected to the frame and jointly forms a passenger compartment with the frame; at least part of the seat assembly is located inside the passenger compartment; at least part of the suspension assembly is connected to the frame, and the suspension assembly includes a rear shock absorber and a rear suspension, and two ends of the rear shock absorber are respectively connected to the frame and the rear suspension; the running assembly is connected to the frame through the suspension assembly, and the running assembly includes a rear wheel mounted on the rear suspension; at least part of the power system is supported by the frame, and the power system includes at least an engine for driving the running assembly; at least part of the heat dissipation system is supported by the frame, and the heat dissipation system includes a first heat dissipation module and a second heat dissipation module connected in parallel or in series with the first heat dissipation module. Both the first heat dissipation module and the second heat dissipation module are communicated with the engine, and both the first heat dissipation module and the second heat dissipation module are arranged at the rear side of the all-terrain vehicle and at least part of them are located on the rear region of the frame. When observing along the length direction of the frame, both the first heat dissipation module and the second heat dissipation module at least partially overlap with the seat assembly.
[0008] Further, the heat dissipation system further includes a pipeline assembly, and the pipeline assembly includes a liquid inlet pipeline and a liquid outlet pipeline. The engine is arranged on the rear region of the frame. The engine has a liquid outlet connected to the liquid inlet pipeline and a liquid inlet connected to the liquid outlet pipeline. Along the fluid flow path flowing out through the liquid inlet pipeline, both the first heat dissipation module and the second heat dissipation module are located between the liquid inlet pipeline and the liquid outlet pipeline.
[0009] The above pipeline assembly realizes the connection between the first heat dissipation module, the second heat dissipation module and the engine. The first heat dissipation module and the second heat dissipation module are arranged in the rear region of the frame. Since the engine is located in the rear region of the frame, the first heat dissipation module and the second heat dissipation module are arranged close to the engine. Then, the length of the pipeline assembly is shortened, the space occupied by the pipeline assembly is reduced, and the cost is reduced at the same time.
[0010] Further, both the rear shock absorber and the rear suspension are located behind the seat assembly, and both the first heat dissipation module and the second heat dissipation module are located between the seat assembly and the rear shock absorber.
[0011] Further, the all-terrain vehicle further includes a cargo box assembly located behind the passenger compartment. The cargo box assembly is at least partially arranged on the frame, and both the first heat dissipation module and the second heat dissipation module are located below the cargo box assembly. In addition, an all-terrain vehicle without a cargo box assembly can also be adopted for the all-terrain vehicle.
[0012] Furthermore, a longitudinal plane perpendicular to the width direction of the frame and passing through the width center of the frame is defined, and the longitudinal plane is located between the first heat dissipation module and the second heat dissipation module.
[0013] Furthermore, the engine is at least partially located between the first heat dissipation module and the second heat dissipation module.
[0014] To reduce the space occupied by the first and second heat dissipation modules along the length of the frame, the first and second heat dissipation modules are gradually tilted toward each other from the front to the rear of the frame. This tilted arrangement reduces the length of the frame, freeing up additional space along the length of the frame.
[0015] Furthermore, the first heat dissipation module includes a first radiator arranged on the frame and a first heat dissipation fan arranged on the first radiator, the second heat dissipation module includes a second radiator arranged on the frame and a second heat dissipation fan arranged on the second radiator, and the first radiator and the second radiator are connected in series or in parallel.
[0016] Furthermore, along the length direction of the frame, the first cooling fan is located behind the first radiator, and the second cooling fan is located behind the second radiator.
[0017] In the aforementioned all-terrain vehicle, the first and second heat dissipation modules are spaced apart along the width of the vehicle frame. The first and second heat dissipation modules are used to dissipate heat from the engine, thereby improving heat dissipation efficiency and achieving excellent heat dissipation effects. During travel, since the first and second heat dissipation modules are both located in the rear region of the vehicle frame, they are less susceptible to external impacts. This reduces the risk of collisions or even penetration by foreign objects, as well as the probability of dirt being lodged and attached, that would otherwise be present if the first and second heat dissipation modules were located at the front. This extends the cleaning and / or maintenance cycle for the first and second heat dissipation modules, thereby reducing the cleaning and / or maintenance costs of the first and second heat dissipation modules and extending their service lives.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.
[0025] Hereinafter, the length direction of the all - terrain vehicle 100 is defined as the front - rear direction, the width direction of the all - terrain vehicle 100 is defined as the left - right direction, and the height direction of the all - terrain vehicle 100 is defined as the up - down direction. For the sake of clearly explaining the technical solution of the present application, the front, rear, left, right, up and down are also defined in Figure 1 the
[0026] As Figure 1 shown in combination with Figure 2 the all - terrain vehicle 100 includes a frame 11, a body cover 12, a seat assembly 13, a suspension assembly 14, a running assembly 15, a power system 16, a cooling system 17 and a cargo box assembly 18. Among them, the body cover 12 is at least partially disposed on the frame 11, and the body cover 12 and the frame 11 together form a passenger compartment 101. The seat assembly 13 is located inside the passenger compartment 101.
[0027] As Figure 2 shown, the above - mentioned cargo box assembly 18 is located behind the passenger compartment 101, and the cargo box assembly 18 is at least partially disposed on the frame 11 to be supported by the frame 11. In this embodiment, the frame 11 includes a chassis 113, and the cargo box assembly 18 is installed above the chassis 113.
[0028] In this embodiment, the running assembly 15 is disposed on the frame 11 through the suspension assembly 14. The suspension assembly 14 is at least partially connected to the frame 11. The suspension assembly 14 includes a front suspension 141, a front shock absorber 142, a rear shock absorber 143 and a rear suspension 144. Along the length direction of the frame 11, the front suspension 141 is located in front of the rear suspension 144. The front shock absorber 142 is located between the frame 11 and the front suspension 141, and the upper and lower ends of the front shock absorber 142 are respectively connected to the frame 11 and the front suspension 141.
[0029] As Figure 1 and Figure 2As shown, the traveling assembly 15 includes a front wheel 151 mounted on the front suspension 141 and a rear wheel 152 mounted on the rear suspension 144. Then, the front wheel 151 is mounted on the frame 11 through the front suspension 141, and the rear wheel 152 is mounted on the frame 11 through the rear suspension 144.
[0030] As Figure 2 shown, the above-mentioned rear shock absorber 143 and rear suspension 144 are both located behind the seat assembly 13. Along the height direction of the frame 11, the rear shock absorber 143 is located between the frame 11 and the rear suspension 144. The upper and lower ends of the rear shock absorber 143 are respectively connected to the frame 11 and the rear suspension 144. That is to say, the upper end of the rear shock absorber 143 is connected to the frame 11, and the lower end of the rear shock absorber 143 is connected to the rear suspension 144.
[0031] As Figure 2 shown, the frame 11 is divided into a front region 111 and a rear region 112 along the length direction. In this embodiment, the rear region 112 of the frame 11 refers to the region on the frame 11 behind the seat assembly 13, and the front region 111 refers to the region on the frame 11 other than the rear region 112.
[0032] In this embodiment, at least part of the above-mentioned power system 16 is supported by the frame 11. As Figure 2 shown, the power system 16 includes an engine 161 disposed on the rear region 112 of the frame 11. The engine 161 is at least used to drive the front wheel 151 and / or the rear wheel 152 of the above-mentioned traveling assembly 15.
[0033] The heat dissipation system 17 is at least partially supported by the frame 11, and the heat dissipation system 17 is used to dissipate heat from the engine 161. As Figure 3 shown, the heat dissipation system 17 includes a pipeline assembly 171, a first heat dissipation module 172, a second heat dissipation module 173, and a water tank 174. The first heat dissipation module 172 and the second heat dissipation module 173 can dissipate heat from the engine 161 simultaneously, improving the heat dissipation efficiency and having a good heat dissipation effect. As Figure 2 and Figure 3As shown, both the first heat dissipation module 172 and the second heat dissipation module 173 are disposed on the rear region 112 of the vehicle frame 11. When observed along the length direction of the vehicle frame 11, both the first heat dissipation module 172 and the second heat dissipation module 173 at least partially overlap with the seat assembly 13. During the travel of the all-terrain vehicle 100, the first heat dissipation module 172 and the second heat dissipation module 173 are not easily impacted by external objects, reducing the probability of being adhered by the raised road dirt, extending the cleaning and / or maintenance cycle of the first heat dissipation module 172 and the second heat dissipation module 173, that is, reducing the cleaning and / or maintenance cost of the first heat dissipation module 172 and the second heat dissipation module 173, and extending the service life of the first heat dissipation module 172 and the second heat dissipation module 173. In addition, since there are no such first heat dissipation module 172 and second heat dissipation module 173 at the front of the vehicle frame 11, the space at the front of the vehicle frame 11 is released, the height at the front of the vehicle frame 11 can be reduced, the driving experience can be improved, and there is better modification space for some aftermarket parts (such as the front cargo box, the front bumper).
[0034] In the present embodiment, both the first heat dissipation module 172 and the second heat dissipation module 173 are located between the cargo box assembly 18 and the chassis 113. That is to say, the first heat dissipation module 172 and the second heat dissipation module 173 are hidden between the cargo box assembly 18 and the chassis 113. Then, the first heat dissipation module 172 and the second heat dissipation module 173 are less likely to be knocked by external objects and contacted by the raised dust.
[0035] As Figure 2 and Figure 3 shown, the first heat dissipation module 172 and the second heat dissipation module 173 are also located between the seat assembly 13 and the rear shock absorber 143. As Figure 3 shown, at least a part of the engine 161 is located between the first heat dissipation module 172 and the second heat dissipation module 173. Then, the engine 161 is arranged adjacent to the first heat dissipation module 172 and the second heat dissipation module 173, shortening the length of the above pipeline assembly and reducing the water flow resistance.
[0036] The second heat dissipation module 173 and the first heat dissipation module 172 are arranged at intervals along the width direction of the vehicle frame 11. The above arrangement avoids the occupation of the space in the length direction of the vehicle frame 11 caused by the arrangement of the first heat dissipation module 172 and the second heat dissipation module 173 along the length direction of the vehicle frame 11, and releases the space in the length direction of the vehicle frame 11. In the present embodiment, as Figure 3 and Figure 4As shown in the figure, the first heat dissipation module 172 is located on the left side of the second heat dissipation module 173. A longitudinal plane 102 perpendicular to the width direction of the vehicle frame 11 and passing through the width center of the vehicle frame 11 is defined, and the longitudinal plane 102 is located between the first heat dissipation module 172 and the second heat dissipation module 173. In this embodiment, the first heat dissipation module 172 and the second heat dissipation module 173 are symmetrically arranged with respect to the longitudinal plane 102.
[0037] As Figure 3 and Figure 4 shown in the figure, both the first heat dissipation module 172 and the second heat dissipation module 173 are gradually inclined towards each other from the front to the rear of the vehicle frame 11. That is to say, the first heat dissipation module 172 is gradually inclined towards the second heat dissipation module 173 from the front to the rear, and the second heat dissipation module 173 is gradually inclined towards the first heat dissipation module 172 from the front to the rear. The above settings further reduce the occupancy of the space in the length direction of the vehicle frame 11.
[0038] In this embodiment, the first heat dissipation module 172 includes a first radiator 1721 disposed on the vehicle frame 11 and a first cooling fan 1722 disposed on the first radiator 1721. The second heat dissipation module 173 includes a second radiator 1731 disposed on the vehicle frame 11 and a second cooling fan 1732 disposed on the second radiator 1731. Along the length direction of the vehicle frame 11, the first cooling fan 1722 is located behind the first radiator 1721, and the second cooling fan 1732 is located behind the second radiator 1731.
[0039] As Figure 3 shown in the figure, the above-mentioned pipeline assembly 171 realizes the connection between the above-mentioned engine 161 and the first heat dissipation module 172 and the second heat dissipation module 173. As Figure 5 and Figure 6 shown in the figure, the pipeline assembly 171 includes a liquid inlet pipeline 1711, a liquid outlet pipeline 1712, a connecting pipeline 1713, a first three-way joint 1714, a second three-way joint 1715, a first pipeline 1716, a second pipeline 1717, a third pipeline 1718, and a fourth pipeline 1719. The engine 161 has a liquid outlet 1611 communicating with the liquid inlet pipeline 1711 and a liquid inlet 1612 communicating with the liquid outlet pipeline 1712. Along the fluid flow path flowing out through the liquid inlet pipeline 1711, both the first heat dissipation module 172 and the second heat dissipation module 173 are located between the liquid inlet pipeline 1711 and the liquid outlet pipeline 1712.
[0040] As [[ID=As shown, the first radiator 1721 is connected to the second radiator 1731 through the connecting pipe 1713. With the above arrangement, the first heat dissipation module 172 and the second heat dissipation module 173 are connected in series. During operation, the coolant absorbs heat from the engine 161, first enters the first radiator 1721 through the liquid inlet pipe 1711, and dissipates part of the heat. Subsequently, the coolant flows into the second radiator 1731 for secondary exchange to further reduce the temperature. After double circulation, the coolant returns to the engine 161 through the liquid outlet pipe 1712 to complete the entire cooling cycle.
[0041] As shown, both the first radiator 1721 and the second radiator 1731 have inlets and outlets. The liquid inlet pipe 1711 is respectively connected to the first end of the first pipe 1716 and the first end of the second pipe 1717 through the first three-way joint 1714. The second end of the first pipe 1716 is connected to the inlet of the first radiator 1721, and the second end of the second pipe 1717 is connected to the inlet of the second radiator 1731. The outlet of the first radiator 1721 is connected to the first end of the third pipe 1718, and the outlet of the second radiator 1731 is connected to the first end of the fourth pipe 1719. The above-mentioned liquid outlet pipe 1712 is respectively connected to the second end of the third pipe 1718 and the second end of the fourth pipe 1719 through the second three-way joint 1715. With the above arrangement, the first heat dissipation module 172 and the second heat dissipation module 173 are connected in parallel.
[0042] During operation, the coolant absorbs heat from the engine 161, and then is divided into two parts through the first three-way joint 1714 and flows to the first radiator 1721 and the second radiator 1731 respectively. After the first radiator 1721 and the second radiator 1731 are fully cooled, they are combined into one through the second three-way joint 1715 and flow back to the engine 161 through the liquid outlet pipe 1712 to complete the entire cooling cycle.
[0043] To replenish the first radiator 1721 and / or the second radiator 1731, as shown, the above-mentioned water tank 174 is arranged on the vehicle frame 11, that is, the water tank 174 is supported by the vehicle frame 11, and the water tank 174 is connected to the first radiator 1721 and / or the second radiator 1731.
[0044] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
