Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0002] An all-terrain vehicle is a vehicle that can travel on any terrain, and is especially suitable for use in complex terrains where ordinary vehicles cannot pass.

[0003] In the prior art, when an all-terrain vehicle is subjected to impact or load, especially when it is subjected to torsional force, the frame of the all-terrain vehicle is easily damaged, resulting in poor handling performance and safety, and thus reducing the driving safety of the all-terrain vehicle. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this application is to provide an all-terrain vehicle with better driving safety.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An all-terrain vehicle includes a frame, body panels, a running gear, a suspension system, and a powertrain. The frame includes a main frame and side support frames mounted on the main frame. The body panels are supported by the frame and include a rear fender mounted on the frame and footrests mounted on the side support frames. The running gear is at least partially located below the frame. The suspension system connects the running gear to the frame. The powertrain is supported by the frame and is drive-connected to the running gear. The side support frames support the footrests. The frame also includes reinforcing tubing for increasing frame rigidity, with at least a portion of the reinforcing tubing located behind the side support frames and at least a portion below the rear fender.

[0007] Furthermore, the lower end of the reinforced pipe is fixedly connected to the side support frame, and the upper end of the reinforced pipe is fixedly connected to the main frame.

[0008] Furthermore, the main frame includes an upper main beam and a lower main beam located below the upper main beam, with side support frames installed on the lower main beam, and the upper end of the reinforcing tube fixedly connected to the upper main beam.

[0009] Furthermore, the connection point between the side support frame and the reinforcing pipe is located at the rear end of the side support frame.

[0010] Furthermore, the foot pedal is at least partially located above the side support frame and is fixedly connected to the side support frame. The reinforcing tube is also provided with a foot pedal mounting point, and the foot pedal is also fixedly connected to the foot pedal mounting point.

[0011] Furthermore, there are two reinforcing tubes and two side support frames. The two side support frames are distributed on both sides of the main frame along the width direction of the frame, and the lower ends of the two reinforcing tubes are respectively connected to the two side support frames.

[0012] Furthermore, the main frame includes an upper main beam, a lower main beam located below the upper main beam, and a longitudinal beam located between the upper and lower main beams. The upper end of the reinforcing tube is fixedly connected to the upper main beam, and the lower end of the reinforcing tube is fixedly connected to the longitudinal beam.

[0013] Furthermore, the upper main beam includes a first main beam and a second main beam distributed along the width direction of the frame, and the lower main beam includes a third main beam and a fourth main beam distributed along the width direction of the frame. The main frame also includes a main beam connector, with the two ends of the main beam connector connected to the first main beam and the second main beam respectively, or the two ends of the main beam connector connected to the third main beam and the fourth main beam respectively; the main beam connector is a double-layer sheet metal structure.

[0014] Furthermore, the main beam connector includes a first sheet metal part and a second sheet metal part located below the first sheet metal part; the front and rear sides of the first sheet metal part extend downwards at least partially to form a front extension and a rear extension, the lower ends of the front extension and the rear extension are fixedly connected to the second sheet metal part, so that the first sheet metal part and the second sheet metal part form a box-shaped structure; or, the first sheet metal part and the second sheet metal part are basically in an "X" shape, and the middle part of the first sheet metal part is fixedly connected to the middle part of the second sheet metal part.

[0015] Furthermore, the front ends of both the first sheet metal part and the second sheet metal part are recessed to the rear to form a front recess, so that the front end surfaces of the first sheet metal part and the second sheet metal part are concave arc surfaces; the rear ends of both the first sheet metal part and the second sheet metal part are recessed to the front to form a rear recess, so that the rear end surfaces of the first sheet metal part and the second sheet metal part are concave arc surfaces.

[0016] The aforementioned all-terrain vehicles can have their frame rigidity and stability enhanced by incorporating reinforcing tubing, particularly when subjected to torsional or other external forces. The area behind the side support frames and below the rear fenders are areas prone to stress concentration during operation. Adding reinforcing tubing to these areas effectively improves frame rigidity and torsional resistance, thereby enhancing the all-terrain vehicle's handling and safety. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19, and an electrical assembly 22.

[0025] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0026] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panel 12, running gear 13, suspension system 14, powertrain 15, transmission assembly 16, fuel system 17, seat assembly 19, and electrical assembly 22. The body panel 12 is at least partially located on and connected to the frame 11, protecting the internal components of the all-terrain vehicle 100. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. The powertrain 15 is drive-connected to the running gear 13; specifically, the transmission assembly 16 drives the powertrain 15 to the running gear 13. The fuel system 17 includes a fuel tank 171 for powering the powertrain 15; specifically, the fuel tank 171 supplies fuel to the powertrain 15. The electrical component 22 is supported by the frame 11, and is also supported by the body panel 12 or the frame 11. The electrical component 22 is used to display the driving data of the all-terrain vehicle 100 and control the operation of the all-terrain vehicle. The seat assembly 19 is supported by the frame 11 and is used to support the driver and / or passengers.

[0027] like Figure 3 and Figure 4 As shown, in one implementation, the body panel 12 includes a rear fender 12b and footrests 27. The rear fender 12b is mounted on the frame 11 and is used to block mud, gravel, and other debris from behind the all-terrain vehicle 100. The footrests 27 are supported by the frame 11 and provide footrests for the driver and passengers. The frame 11 also includes a main frame 113, side support frames 114, and reinforcing tubes 115. The main frame 113 extends substantially along the length of the frame 11. The side support frames 114 are located on both sides of the main frame 113 along the width of the frame 11 and are connected to the main frame 113. The side support frames 114 are located at the end of the main frame 113 closer to the ground and are used to mount and support the footrests 27. The reinforcing tube 115 is mounted on the main frame 113. The reinforcing tube 115 is at least partially located behind the side support frame 114 and at least partially located below the rear fender 12b.

[0028] This application incorporates reinforcing tubing 115 to distribute the force on the frame 11 when subjected to torque or other external forces, thereby reducing local deformation of the frame 11 and enhancing its rigidity and stability. The area behind the side support frame 114 and below the rear fender 12b are areas prone to stress concentration during operation of the all-terrain vehicle 100. By adding reinforcing tubing 115 to these areas, the rigidity and torsional resistance of the frame 11 can be effectively improved, thus enhancing the handling performance and safety of the all-terrain vehicle 100.

[0029] As one implementation method, the lower end of the reinforced tube 115 is fixedly connected to the side support frame 114, which helps to disperse and withstand the impact force from the side of the all-terrain vehicle 100, enhancing the torsional and bending resistance of the frame 11. The upper end of the reinforced tube 115 is fixedly connected to the main frame 113, further enhancing the rigidity and stability of the frame 11, thereby improving the handling performance of the all-terrain vehicle 100 in complex road conditions. It should be noted that the lower end of the reinforced tube 115 is fixedly connected to the side support frame 114 by welding or bolting, and the upper end of the reinforced tube 115 is fixedly connected to the main frame 113 by welding or bolting.

[0030] Specifically, the main frame 113 includes an upper main beam 1131 and a lower main beam 1132. The lower main beam 1132 is located below the upper main beam 1131, and a side support frame 114 is installed on the lower main beam 1132. The upper end of the reinforcing tube 115 is fixedly connected to the upper main beam 1131. This application enhances the stability and load-bearing capacity of the main frame 113 by connecting the upper main beam 1131 and the lower main beam 1132 through the reinforcing tube 115, thereby improving the rigidity and strength of the main frame 113.

[0031] Specifically, the connection point between the side support frame 114 and the reinforcing tube 115 is located at the rear end of the side support frame 114, thereby improving the stability of the side support frame 114 and increasing the support force of the frame 11 on the side support frame 114. Especially when the side support frame 114 is subjected to heavy loads or impacts, the reinforcing tube 115 can effectively distribute the force, reducing the risk of deformation and damage to the side support frame 114. In addition, the above arrangement can avoid interfering with the installation of the foot pedal 27.

[0032] More specifically, the foot pedal 27 is at least partially located above and fixedly connected to the side support frame 114. The reinforcing tube 115 also has foot pedal mounting points, and the foot pedal 27 is fixedly connected to these mounting points. This not only improves the installation accuracy of the foot pedal 27 but also ensures its stability during use, preventing potential safety accidents caused by loosening or displacement of the foot pedal 27.

[0033] More specifically, two reinforcing tubes 115 and two side support frames 114 are provided. The two side support frames 114 are distributed on both sides of the main frame 113 along the width direction of the frame 11. The lower ends of the two reinforcing tubes 115 are respectively connected to the two side support frames 114. The reinforcing tubes 115 and the side support frames 114 are provided on both sides of the main frame 113 so as to increase the rigidity and stability of the main frame 113 when the all-terrain vehicle 100 is subjected to torsional forces or external forces in different directions.

[0034] As another implementation, the main frame 113 also includes a longitudinal beam 1133, which is located between the upper main beam 1131 and the lower main beam 1132. The upper end of the reinforcing tube 115 is fixedly connected to the upper main beam 1131, and the lower end of the reinforcing tube 115 is fixedly connected to the longitudinal beam 1133, so that the upper main beam 1131, the longitudinal beam 1133, and the reinforcing tube 115 form a triangular support structure, thereby improving the structural stability and load-bearing capacity of the main frame 113.

[0035] In one implementation, the upper main beam 1131 includes a first main beam 1131a and a second main beam 1131b distributed along the width direction of the frame 11, and the lower main beam 1132 includes a third main beam 1132a and a fourth main beam 1132b distributed along the width direction of the frame 11. The main frame 113 also includes a main beam connector 116, with its two ends connected to the first main beam 1131a and the second main beam 1131b, or its two ends connected to the third main beam 1132a and the fourth main beam 1132b. The main beam connector 116 is used to connect the first main beam 1131a and the second main beam 1131b, or to connect the third main beam 1132a and the fourth main beam 1132b, to ensure the stability and integrity of the main frame 113.

[0036] Specifically, the main beam connector 116 has a double-layer sheet metal structure, which enhances the rigidity and strength of the main beam connector 116, thereby improving the stability and load-bearing capacity of the entire main frame 113.

[0037] As one implementation, the main beam connector 116 includes a first sheet metal part 1161 and a second sheet metal part 1162, with the second sheet metal part 1162 located below the first sheet metal part 1161.

[0038] like Figure 5As shown, as an alternative implementation, the front and rear sides of the first sheet metal part 1161 extend downwards at least partially to form a front extension and a rear extension. The lower ends of both the front and rear extensions are fixedly connected to the second sheet metal part 1162, so that the first sheet metal part 1161 and the second sheet metal part 1162 form a box-shaped structure. The main beam connector 116 with the box-shaped structure is lightweight and has high structural strength, thereby making the main frame 113 lighter and improving the structural stability and load-bearing capacity of the main frame 113.

[0039] like Figure 6 As shown, as another alternative implementation, the first sheet metal part 1161 and the second sheet metal part 1162 are basically in an "X" shape, with the middle part of the first sheet metal part 1161 and the middle part of the second sheet metal part 1162 fixedly connected. The "X" shaped main beam connector 116 can provide stable connection and support, and can improve the torsional stiffness of the main frame 113, thereby enhancing the stability of the main frame 113 and thus improving the driving stability of the all-terrain vehicle 100.

[0040] It should be noted that the main beam connector 116 connecting the first main beam 1131a and the second main beam 1131b, and the main beam connector 116 connecting the third main beam 1132a and the fourth main beam 1132b can all adopt at least one of the above-mentioned box-shaped structure and "X"-shaped structure.

[0041] Specifically, the front ends of both the first sheet metal part 1161 and the second sheet metal part 1162 are recessed rearward to form a front recess 1163, so that the front surface of the first sheet metal part 1161 and the second sheet metal part 1162 is a concave arc surface. The rear ends of both the first sheet metal part 1161 and the second sheet metal part 1162 are recessed forward to form a rear recess 1164, so that the rear surface of the first sheet metal part 1161 and the second sheet metal part 1162 is a concave arc surface. The above structure makes the main beam connector 116 have a shape that is wide at both ends and narrow in the middle, which not only improves the structural strength of the connection with the upper main beam 1131 or the lower main beam 1132, but also reduces the mass of the main beam connector 116 and improves the torsional stiffness of the main frame 113, thereby making the main frame 113 lighter and improving the structural stability and load-bearing capacity of the main frame 113.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
