Technical Field
[0001] This invention relates to the field of vehicles, and in particular to an all-terrain vehicle. Background Technology
[0002] Currently, most all-terrain vehicle radiators are installed at the front of the vehicle to increase the heat dissipation area and accelerate cooling. To further accelerate the cooling of the heat transferred from the radiator, a fan is usually installed behind the radiator to work in conjunction with it and improve the cooling effect.
[0003] Due to their small size, all-terrain vehicles (ATVs) have limited interior space, thus requiring specific space for the placement of their components. Existing radiator structures are complex and have multiple mounting points for other components, increasing the space required for the radiator and hindering the efficient use of space in ATVs. Summary of the Invention

Along the vertical direction of the all-terrain vehicle 100, the upper main beam 115 is located on the upper side, and the lower main beam 116 is located on the lower side. The first support column 111, the second support column 112, the third support column 113, and the fourth support column 114 are all located between the upper main beam 115 and the lower main beam 116. Specifically, the first support column 111 includes a first pipe component 1111, a second pipe component 1112, and a first sheet metal component 1113. The second support 112 includes a third pipe fitting 1121 and a fourth pipe fitting 1122. The third support 113 includes a fifth pipe fitting 1131, a sixth pipe fitting 1132, a seventh pipe fitting 1133, an eighth pipe fitting 1134, and a second sheet metal part 1135. The fourth support 114 includes a ninth pipe fitting 1141 and a tenth pipe fitting 1142. The upper main beam 115 includes a first main beam 1151 and a second main beam 1152.

The other end of the first sheet metal part 1113 is connected to the third main beam 1161. One end of the second pipe fitting 1112 is connected to the second main beam 1152, and the other end of the second pipe fitting 1112 is connected to one end of the first sheet metal part 1113. The other end of the first sheet metal part 1113 is connected to the fourth main beam 1162. One end of the third pipe fitting 1121 is connected to the first main beam 1151, and the other end of the third pipe fitting 1121 is connected to the third main beam 1161. One end of the fourth pipe fitting 1122 is connected to the second main beam 1152, and the other end of the fourth pipe fitting 1122 is connected to the third main beam 1161. One end of the fifth pipe fitting 1131 is connected to the first main beam 1151, and the other end of the fifth pipe fitting 1131 is connected to one end of the seventh pipe fitting 1133. One end of the sixth pipe fitting 1132 is connected to the first main beam 1151, and the other end of the sixth pipe fitting 1132 is connected to the other end of the seventh pipe fitting 1133. One end of the eighth pipe fitting 1134 is connected to the third main beam 1161, and the other end of the eighth pipe fitting 1134 is connected to the fourth main beam 1162. The seventh pipe fitting 1133 and the eighth pipe fitting 1134 are connected by the second sheet metal part 1135. One end of the ninth pipe fitting 1141 is connected to the first main beam 1151, and the other end of the ninth pipe fitting 1141 is connected to the third main beam 1161. One end of the tenth pipe fitting 1142 is connected to the second main beam 1152, and the other end of the tenth pipe fitting 1142 is connected to the fourth main beam 1162.
[0035] In this embodiment, along the left-right direction of the all-terrain vehicle 100, the first main beam 1151 is located to the left of the second main beam 1152, the third main beam 1161 is located to the left of the fourth main beam 1162, the first pipe 1111 is located to the left of the second pipe 1112, the third pipe 1121 is located to the left of the fourth pipe 1122, the fifth pipe 1131 is located to the left of the sixth pipe 1132, and the ninth pipe 1141 is located to the left of the tenth pipe 1142. Along the vertical direction of the all-terrain vehicle 100, the first pipe 1111 and the second pipe 1112 are both located on the upper side of the first sheet metal part 1113, the first main beam 1151 is located on the upper side of the third main beam 1161, the second main beam 1152 is located on the upper side of the fourth main beam 1162, the seventh pipe 1133 is located on the upper side of the eighth pipe 1134, the fifth pipe 1131 and the sixth pipe 1132 are both located on the upper side of the seventh pipe 1133, and the second sheet metal part 1135 is located on the lower side of the seventh pipe 1133 and on the upper side of the eighth pipe 1134. With the above configuration, the first pillar 111, second pillar 112, third pillar 113, fourth pillar 114, upper main beam 115, and lower main beam 116 constitute the basic frame of the vehicle frame 11, thereby improving the strength of the vehicle frame 11. Furthermore, by optimizing the structure of the first pillar 111, second pillar 112, third pillar 113, fourth pillar 114, upper main beam 115, and lower main beam 116—specifically by replacing tubular components with sheet metal structures—the number of tubular components in the vehicle frame 11 is reduced, thereby lowering the weight of the all-terrain vehicle 100 and achieving lightweighting of both the vehicle frame 11 and the all-terrain vehicle 100. Specifically, replacing the tubular components of the lower half of the first pillar 111 with sheet metal parts facilitates the fixed connection of the first pillar 111, and the sheet metal parts facilitate the installation of components of the all-terrain vehicle 100, improving the assemblability of the all-terrain vehicle 100. Specifically, some tubular components of the third pillar 113 are replaced with sheet metal parts. The above-described configuration reduces the need for mounting structures, improves the integration of the frame 11, and facilitates the lightweighting of the frame 11. In this embodiment, the frame 11 can be made of a high-strength 20CrMo material, thereby increasing the strength of the frame 11 and reducing its weight.
[0036] In one implementation, the all-terrain vehicle 100 includes a symmetry plane 101 perpendicular to the left-right direction, and the all-terrain vehicle 100 is substantially symmetrical about the symmetry plane 101. The frame 11 is also substantially symmetrical about the symmetry plane 101. Specifically, the first pipe 1111 and the second pipe 1112 are substantially symmetrical about the symmetry plane 101, the third pipe 1121 and the fourth pipe 1122 are substantially symmetrical about the symmetry plane 101, the fifth pipe 1131 and the sixth pipe 1132 are substantially symmetrical about the symmetry plane 101, the ninth pipe 1141 and the tenth pipe 1142 are substantially symmetrical about the symmetry plane 101, the first main beam 1151 and the second main beam 1152 are substantially symmetrical about the symmetry plane 101, and the third main beam 1161 and the fourth main beam 1162 are substantially symmetrical about the symmetry plane 101. In this embodiment, the seventh pipe 1133 extends substantially in the left-right direction, and the eighth pipe 1134 extends substantially in the left-right direction.
[0037] In one implementation, the first strut 111, the second strut 112, the upper main beam 115, and the lower main beam 116 form a first space; the second strut 112, the third strut 113, the upper main beam 115, and the lower main beam 116 form a second space; and the third strut 113, the fourth strut 114, the upper main beam 115, and the lower main beam 116 form a third space. The front suspension 131 is at least partially disposed in the first space, that is, at least partially disposed between the first strut 111 and the second strut 112. The powertrain 14 is at least partially disposed in the second space, that is, at least partially disposed between the second strut 112 and the third strut 113. The rear suspension 132 is at least partially disposed in the third space, that is, at least partially disposed between the third strut 113 and the fourth strut 114. Specifically, at least a portion of the rear suspension 132 is disposed on the third strut 113. In this embodiment, at least a portion of the rear suspension 132 is mounted on the second sheet metal part 1135.
[0038] like Figure 4 and Figure 5As shown, in one implementation, the suspension assembly 13 also includes a steering knuckle 135. The steering knuckle 135 is at least partially connected to the first travel wheel 121 and at least partially connected to the front suspension 131. The steering knuckle 135 is used to transmit and bear the front load of the all-terrain vehicle 100 and drive the deflection of the first travel wheel 121, thereby realizing the steering of the all-terrain vehicle 100. Specifically, one end of the steering knuckle 135 is provided with a first connecting end 1351, and the other end of the steering knuckle 135 is provided with a second connecting end 1352. The front suspension 131 includes a front rocker arm 1311. One end of the front rocker arm 1311 is connected to the vehicle frame 11, and the first connecting end 1351 and the second connecting end 1352 of the steering knuckle 135 are both connected to the other end of the front rocker arm 1311. The front rocker arm 1311 includes an upper rocker arm 1311a and a lower rocker arm 1311b. A first connecting end 1351 of the steering knuckle 135 is connected to one end of the upper rocker arm 1311a, and the other end of the upper rocker arm 1311a is connected to the vehicle frame 11. A second connecting end 1352 of the steering knuckle 135 is connected to one end of the lower rocker arm 1311b, and the other end of the lower rocker arm 1311b is connected to the vehicle frame 11. This configuration allows for a stable connection between the steering knuckle 135 and the front suspension 131. In this embodiment, the steering knuckle 135 includes a first body 1353 and a connecting member 1354. One end of the first body 1353 has the first connecting end 1351, and the other end of the first body 1353 has the second connecting end 1352. The connecting member 1354 connects the upper rocker arm 1311a and the first connecting end 1351, thereby achieving a stable connection between the steering knuckle 135 and the upper rocker arm 1311a.
[0039] As one implementation, an adjusting shim 1355 is provided between the first connecting end 1351 and the connecting member 1354. The adjusting shim 1355 is used to change the camber angle of the first traveling wheel 121, thereby compensating for manufacturing errors and improving the handling characteristics of the all-terrain vehicle 100. Furthermore, by changing the camber angle of the first traveling wheel 121, the adjusting shim 1355 enables the all-terrain vehicle 100 to have good traction under extreme working conditions, improving the safety of the all-terrain vehicle 100. The thickness of the adjusting shim 1355 is a preset thickness, which can be adjusted according to actual needs to achieve adjustment of the camber angle of the first traveling wheel 121. The end face of the first connecting end 1351 includes at least a first end face and a second end face, which are substantially symmetrically arranged about the end face of the first connecting end 1351. The adjusting shim 1355 abuts against the first end face or the second end face. Along a direction perpendicular to the end face of the first connecting end 1351, the projection of the adjusting shim 1355 onto the end face of the first connecting end 1351 is called the projection surface, and the area of the end face of the first connecting end 1351 is called the end face area. The area of the projection surface is less than or equal to half of the end face area. The projection surface can substantially coincide with the first end face or substantially coincide with the second end face. Specifically, the end face of the first connecting end 1351 is provided with a plurality of first connecting holes 1351a. The centers of the plurality of first connecting holes 1351a are substantially on the same straight line. The line connecting the centers of the plurality of first connecting holes 1351a is a fifth straight line 1351b. The fifth straight line 1351b divides the end face of the first connecting end 1351 into a first end face and a second end face. Along the vertical direction of the all-terrain vehicle 100, the first end face is at least partially located on the upper side of the second end face. The profile of the cross-section of the adjusting shim 1355 can be basically consistent with the profile of the first end face or the profile of the second end face, thereby facilitating the improvement of the installation stability of the adjusting shim 1355.
[0040] The adjusting shim 1355 has several first half-holes 1355a, and the connector 1354 has several second connecting holes 1354a. The centers of the first connecting holes 1351a, the first half-holes 1355a, and the second connecting holes 1354a are substantially on the same straight line, allowing the first connecting holes 1351a, the first half-holes 1355a, and the second connecting holes 1354a to be connected sequentially through the same fastener, facilitating the installation of the first connecting end 1351, the adjusting shim 1355, and the connector 1354. Specifically, one side of the adjusting shim 1355 abuts against the first end face or the second end face, and the other side of the adjusting shim 1355 abuts against the connector 1354. At this point, the fastener passes sequentially through the second connecting hole 1354a, the first half-hole 1355a, and the first connecting hole 1351a, thereby achieving a stable connection between the connector 1354, the adjusting shim 1355, and the first connecting end 1351. In this embodiment, the connector 1354 can be a lifting lug, and the fastener can be a bolt.
[0041] As one implementation, the adjusting shim 1355 is provided with a slot 1355b. The slot 1355b is used to reduce the weight of the adjusting shim 1355, which is beneficial to the lightweighting of the all-terrain vehicle 100. Several first half-holes 1355a can be provided on both sides of the length direction of the slot 1355b. Specifically, the setting of the slot 1355b makes the adjusting shim 1355 basically "C" shaped, and along the vertical direction of the all-terrain vehicle 100, the slot opening of the slot 1355b is basically downward. Through the above arrangement, the outer contour of the adjusting shim 1355 is basically consistent with the contour of the first end face, which facilitates the installation of the adjusting shim 1355 and does not affect the installation of other components.
[0042] In one implementation, the number of first connecting holes 1351a, first half-holes 1355a, and second connecting holes 1354a are all two. Specifically, the two first half-holes 1355a are arranged on both sides of the slot 1355b, that is, the slot 1355b is at least partially arranged between the two first half-holes 1355a, which facilitates the improvement of the space utilization of the adjusting shim 1355, thereby making the structure of the adjusting shim 1355 more compact.
[0043] Understandably, the end face of the first connecting end 1351 also includes a line of symmetry, and the two first connecting holes 1351a are arranged symmetrically about the line of symmetry. The first end face and the second end face can also be arranged symmetrically about the line of symmetry.
[0044] like Figure 6As shown, as one implementation, the steering knuckle 135 can also be located at the rear of the frame 11. Specifically, the steering knuckle 135 is at least partially connected to the second travel wheel 122 and at least partially connected to the rear suspension 132. The rear suspension 132 includes a rear swing arm 1321. One end of the rear swing arm 1321 is connected to the frame 11, and both the first connecting end 1351 and the second connecting end 1352 are connected to the other end of the rear swing arm 1321. Specifically, the steering knuckle 135 can also be integrally formed with the rear swing arm 1321, and the ends of the steering knuckle 135 and the rear swing arm 1321 away from the frame 11 are integrally formed, thereby making the structure of the steering knuckle 135 and the rear swing arm 1321 more compact and easier to process and assemble.
[0045] like Figure 4As shown, in one implementation, the front suspension 131 includes a first shock absorber 1312. One end of the first shock absorber 1312 is connected to the vehicle frame 11, and the other end is connected to the front rocker arm 1311. Specifically, one end of the first shock absorber 1312 is provided with a first mounting point 1312a, and the other end is provided with a second mounting point 1312b. The first mounting point 1312a is connected to the vehicle frame 11, and the second mounting point 1312b is connected to the front rocker arm 1311. In this embodiment, the body panel 25 includes a first lampshade 251, which is at least partially disposed on the vehicle frame 11 and located on the front side of the vehicle frame 11. The first lampshade 251 is used to house the headlight on the front side of the all-terrain vehicle 100. In a projection plane 103 perpendicular to the longitudinal direction of the all-terrain vehicle 100, the projection of the uppermost end of the first lampshade 251 along the longitudinal direction onto the projection plane 103 is a first projection line. The front rocker arm 1311 includes an upper rocker arm 1311a. The upper rocker arm 1311a is disposed below the first lamp cover 251. The projection of the axis of the upper rocker arm 1311a along the front-rear direction onto the projection plane 103 is a second projection line. One end of the upper rocker arm 1311a is provided with a third mounting point 1311c, and the other end of the upper rocker arm 1311a is provided with a fourth mounting point 1311d. The third mounting point 1311c is used to connect to the steering knuckle 135, and the fourth mounting point 1311d is used to connect to the frame 11. The upper rocker arm 1311a includes a sixth straight line 1311e extending in the vertical direction and passing through the third mounting point 1311c, and the upper rocker arm 1311a also includes a seventh straight line 1311f extending in the vertical direction and passing through the fourth mounting point 1311d. The projection of the sixth straight line 1311e along the front-rear direction onto the projection plane 103 is the third projection line, and the projection of the seventh straight line 1311f along the front-rear direction onto the projection plane 103 is the fourth projection line. The first projection line, the second projection line, the third projection line, and the fourth projection line enclose the third projection plane M1. The projection of the first mounting point 1312a along the front-rear direction onto the projection plane 103 is the fourth projection plane. The fourth projection plane is located within the third projection plane M1, that is, the third projection plane M1 covers the fourth projection plane. Through the above arrangement, the installation of the first shock absorber 1312 can have a smaller impact on the installation of the tubular components of the frame 11, that is, the installation of the first shock absorber 1312 can have a smaller impact on the installation of other components of the all-terrain vehicle 100. Furthermore, through the above-mentioned arrangement, the first mounting point 1312a can be positioned on the lower side of the uppermost end of the first lamp cover 251, which can reduce the intrusion of mud and sand caused by the exposure of the first shock absorber 1312, thereby improving the service life of the first shock absorber 1312. It can also lower the center of gravity height of the all-terrain vehicle 100, thereby improving the operational stability of the all-terrain vehicle 100. The first mounting point 1312a can be connected to the frame 11 through sheet metal parts or other connecting components, so that the fourth projection surface can be located within the third projection surface M1.
[0046] In this embodiment, the front rocker arm 1311 further includes a lower rocker arm 1311b. The lower rocker arm 1311b is disposed below the upper rocker arm 1311a. The projection of the axis of the lower rocker arm 1311b along the front-rear direction onto the projection plane 103 is the fifth projection line. One end of the lower rocker arm 1311b is provided with a fifth mounting point 1311g, and the other end of the lower rocker arm 1311b is provided with a sixth mounting point 1311h. Wherein, when the lower rocker arm 1311b is a straight tube, the axis of the lower rocker arm 1311b points to the axis of the straight tube; when the lower rocker arm 1311b is a curved tube, the axis of the lower rocker arm 1311b points to the line connecting the fifth mounting point 1311g and the sixth mounting point 1311h. The fifth mounting point 1311g is used to connect the steering knuckle 135, and the sixth mounting point 1311h is used to connect the frame 11. The lower rocker arm 1311b includes an eighth straight line 1311j extending in the vertical direction and passing through a fifth mounting point 1311g. The lower rocker arm 1311b also includes a ninth straight line 1311k extending in the vertical direction and passing through a sixth mounting point 1311h. The projection of the eighth straight line 1311j onto the projection plane 103 in the front-back direction is the sixth projection line, and the projection of the ninth straight line 1311k onto the projection plane 103 in the front-back direction is the seventh projection line. Furthermore, the upper rocker arm 1311a includes a tenth straight line 1311m parallel to the axis of the upper rocker arm 1311a, and the tenth straight line 1311m is located above the axis of the upper rocker arm 1311a. The projection of the tenth straight line 1311m onto the projection plane 103 in the front-back direction is the eighth projection line. The distance between the eighth projection line and the second projection line is L, which is the distance between the projection of the tenth straight line 1311m on the projection plane 103 and the projection of the axis of the upper rocker arm 1311a on the projection plane 103 along the front-rear direction. L can be greater than or equal to 0 mm and less than or equal to 50 mm. The fifth, sixth, seventh, and eighth projection lines form the fifth projection surface M2. The projection of the second mounting point 1312b along the front-rear direction on the projection plane 103 is the sixth projection surface. The sixth projection surface is located within the fifth projection surface M2, meaning the fifth projection surface M2 covers the sixth projection surface. Through the above arrangement, the stroke of the first shock absorber 1312 can be increased, facilitating the structural design of the first shock absorber 1312, improving the wheel travel of the all-terrain vehicle 100, enhancing the comfort of the all-terrain vehicle 100, and effectively improving the space utilization of the all-terrain vehicle 100. The wheel travel refers to the sum of the upward and downward displacements of the walking component 12 during the travel of the all-terrain vehicle 100. Furthermore, the second mounting point 1312b can be connected to the front rocker arm 1311 via sheet metal or other connecting parts, thereby allowing the sixth projection plane to be located within the fifth projection plane M2.
[0047] Furthermore, the above-mentioned arrangement can minimize the impact of the mounting point of the first shock absorber 1312 on other components of the all-terrain vehicle 100, making the structure of the all-terrain vehicle 100 more compact, thereby improving the operational stability of the all-terrain vehicle 100.
[0048] like Figure 4 As shown, in one implementation, the shortest distance between the third mounting point 1311c and the fourth mounting point 1311d is L1, that is, the distance between the two mounting points of the upper rocker arm 1311a is L1. The shortest distance between the fifth mounting point 1311g and the sixth mounting point 1311h is L2, that is, the distance between the two mounting points of the lower rocker arm 1311b is L2. The ratio of L1 to L2 is greater than or equal to 0.5 and less than or equal to 1.15. Specifically, the ratio of L1 to L2 is greater than or equal to 0.6 and less than or equal to 1.1. In this embodiment, the ratio of L1 to L2 is greater than or equal to 0.7 and less than or equal to 1. Through the above settings, during the upward jump of the first travel wheel 121, the structural relationship and mounting point settings of the upper rocker arm 1311a and the lower rocker arm 1311b cause the camber angle of the first travel wheel 121 to change in a negative direction, which is beneficial to improving the tire grip of the all-terrain vehicle 100 when cornering. At the same time, the kingpin inclination angle changes in a positive direction, which is beneficial to increasing the return torque of the first travel wheel 121, thereby helping to improve the handling performance of the all-terrain vehicle 100. Among them, the kingpin inclination angle refers to the angle at which the kingpin axis tilts towards the inside of the vehicle body when the first travel wheel 121 is viewed from the front-rear direction of the all-terrain vehicle 100.
[0049] like Figure 7As shown, in one implementation, during the movement of the all-terrain vehicle 100, the walking component 12 includes at least a first position, a second position, and an initial position. When the walking component 12 is in the first position, it is at the highest point of its upward jump; when it is in the second position, it is at the lowest point of its downward jump; and when it is in the initial position, it is at the position it was in when the all-terrain vehicle 100 is stationary. The maximum distance between the first position and the initial position is the upward jump distance L3 of the walking component 12, and the maximum distance between the second position and the initial position is the downward jump distance L4. The ratio of L3 to L4 is greater than or equal to 1 and less than or equal to 10. Specifically, the ratio of L3 to L4 is greater than or equal to 2 and less than or equal to 9. In this embodiment, the ratio of L3 to L4 is greater than or equal to 3 and less than or equal to 8. Through the above settings, the wheel jump distance can be controlled within a certain range, thereby ensuring good passability of the all-terrain vehicle 100 and improving its comfort. Wherein, the line connecting the left and right wheel centers when the traveling component 12 is in the first position is the first wheel line; the line connecting the left and right wheel centers when the traveling component 12 is in the initial position is the second wheel line; and the line connecting the left and right wheel centers when the traveling component 12 is in the second position is the third wheel line. L3 can be the distance between the first wheel line and the second wheel line, and L4 can be the distance between the second wheel line and the third wheel line. The left and right wheel centers refer to the wheel centers of the left and right wheels of the first traveling wheel 121, or the wheel centers of the left and right wheels of the second traveling wheel 122.
[0050] In one implementation, the sum of the upward and downward travel of the walking assembly 12 is L5, which is equal to the sum of L3 and L4, i.e., the wheel travel is L5. Here, the wheel travel L5 refers to the maximum distance between the first position and the second position. The travel of the first shock absorber 1312 is L6, which refers to the distance from its shortest compression to its longest extension. The ratio of L5 to L6 is greater than or equal to 1.1 and less than or equal to 2. Specifically, the ratio of L5 to L6 is greater than or equal to 1.2 and less than or equal to 1.9. In this embodiment, the ratio of L5 to L6 is greater than or equal to 1.3 and less than or equal to 1.8. Through the above settings, during the upward and / or downward travel of the walking assembly 12, the first shock absorber 1312 can have a better travel to evenly absorb the impact of the road surface, thereby effectively buffering the road impact and facilitating the design and manufacturing of the first shock absorber 1312. In this embodiment, the rear suspension 132 includes a second shock absorber. The stroke of the second shock absorber is basically the same as that of the first shock absorber 1312. That is, the ratio of the strokes of L5 and the second shock absorber is the first ratio, and the ratio of L5 to L6 is the second ratio. The first ratio and the second ratio are the same, so that during the upward and / or downward movement of the walking assembly 12, the second shock absorber can have a better stroke to evenly absorb the impact of the road surface, thereby effectively buffering the impact of the road surface and facilitating the design and manufacturing of the second shock absorber.
[0051] like Figure 8 As shown, in one implementation, the frame 11 includes a lowest point S1 along the vertical direction, which is the point on the lowest end face of the lower main beam 116. It is understood that the surface of the running gear 12 in contact with the ground is a horizontal plane. The horizontal plane is substantially perpendicular to the vertical direction of the all-terrain vehicle 100. The distance between the lowest point S1 and the horizontal plane is H, that is, the distance between the lowest point S1 of the frame 11 and the ground is H. The radius of the running gear 12 is R, that is, the radius of the wheels of the all-terrain vehicle 100 is R. The ratio of R to H is greater than or equal to 0.9 and less than or equal to 1.4. Specifically, the ratio of R to H is greater than or equal to 1 and less than or equal to 1.3. Here, R can be the radius of the first running wheel 121, or R can be the radius of the second running wheel 122. Since the distance between the lowest point of the all-terrain vehicle 100 and the ground has a significant impact on the center of gravity height of the all-terrain vehicle 100, the above-mentioned settings can improve the handling and stability performance of the all-terrain vehicle 100, and enable the all-terrain vehicle 100 to have good passability and increase wheel travel, which is beneficial to the structural design and manufacturing of the first shock absorber 1312 and the second shock absorber.
[0052] like Figure 9As shown, in one implementation, the first traveling wheel 121 includes a first front wheel 1211 and a second front wheel 1212. The first front wheel 1211 includes a first symmetry plane 1211a perpendicular to the left-right direction, and the first front wheel 1211 is substantially symmetrical about the first symmetry plane 1211a. The second front wheel 1212 includes a second symmetry plane 1212a perpendicular to the left-right direction, and the second front wheel 1212 is substantially symmetrical about the second symmetry plane 1212a. The second traveling wheel 122 includes a first rear wheel 1221 and a second rear wheel 1222. The first rear wheel 1221 includes a third symmetry plane 1221a perpendicular to the left-right direction, and the first rear wheel 1221 is substantially symmetrical about the third symmetry plane 1221a. The second rear wheel 1222 includes a fourth symmetry plane 1222a perpendicular to the left-right direction, and the second rear wheel 1222 is substantially symmetrical about the fourth symmetry plane 1222a. The distance between the first symmetry plane 1211a and the second symmetry plane 1212a is the first wheelbase D1, and the distance between the third symmetry plane 1221a and the fourth symmetry plane 1222a is the second wheelbase D2. The ratio of the first wheelbase D1 to the second wheelbase D2 is greater than or equal to 0.8 and less than or equal to 1.3. Specifically, the ratio of the first wheelbase D1 to the second wheelbase D2 is greater than or equal to 0.9 and less than or equal to 1.2. In this embodiment, the ratio of the first wheelbase D1 to the second wheelbase D2 is greater than or equal to 1 and less than or equal to 1.1. Through the above settings, the passability of the all-terrain vehicle 100 can be improved, the load transfer on the front axle of the all-terrain vehicle 100 can be reduced, and the all-terrain vehicle 100 can tend to understeer, which is beneficial to the arrangement of the steering mechanism of the all-terrain vehicle 100. Here, the steering mechanism refers to the components used for steering in the all-terrain vehicle 100, and the front axle of the all-terrain vehicle 100 refers to the connecting shaft between the first front wheel 1211 and the second front wheel 1212.
[0053] In one implementation, the first front wheel 1211, the second front wheel 1212, the first rear wheel 1221, and the second rear wheel 1222 all extend substantially along the longitudinal direction of the all-terrain vehicle 100. The first front wheel 1211 and the first rear wheel 1221 are both located on the left side of the all-terrain vehicle 100, while the second front wheel 1212 and the second rear wheel 1222 are both located on the right side of the all-terrain vehicle 100. The left end face of the first front wheel 1211 is the first end face, and the right end face of the second front wheel 1212 is the second end face. The left end face of the first rear wheel 1221 is the third end face, and the right end face of the second rear wheel 1222 is the fourth end face. The first, second, third, and fourth end faces are all substantially perpendicular to the left-right direction. The distance between the first and second end faces is the first end distance D3, which is the distance between the outer surfaces of the first front wheel 1211 and the second front wheel 1212. The distance between the third and fourth end faces is the second end distance D4, which is the distance between the outer side of the first rear wheel 1221 and the outer side of the second rear wheel 1222. The ratio of the first end distance D3 to the second end distance D4 is greater than or equal to 0.8 and less than or equal to 1.5. Specifically, the ratio of the first end distance D3 to the second end distance D4 is greater than or equal to 0.9 and less than or equal to 1.4. In this embodiment, the ratio of the first end distance D3 to the second end distance D4 is greater than or equal to 1 and less than or equal to 1.3. Through the above settings, the passability of the all-terrain vehicle 100 can be improved, the load transfer on the front axle of the all-terrain vehicle 100 can be reduced, the all-terrain vehicle 100 tends to understeer, and this is beneficial to the arrangement of the steering mechanism of the all-terrain vehicle 100.
[0054] like Figures 10 to 13As shown, in one implementation, the heat dissipation assembly 22 includes a cooling module 221. The mounting bracket assembly 16 includes a front bracket 164 and a fifth mounting bracket 168. The front bracket 164 is disposed on the front side of the frame 11. The fifth mounting bracket 168 is at least partially disposed on the frame 11 and is used to connect the suspension assembly 13 and the frame 11. The cooling module 221 is at least partially disposed on the front bracket 164 and at least partially disposed on the frame 11. Specifically, the fifth mounting bracket 168 includes a first shock absorber bracket 1681 and a connecting bracket 1682. The first shock absorber bracket 1681 is at least partially disposed on the front side of the frame 11 and is at least partially disposed between the first main beam 1151 and the second main beam 1152. The connecting bracket 1682 is at least partially disposed on the first shock absorber bracket 1681 and at least partially disposed on the frame 11. The cooling module 221 is at least partially disposed on the frame 11 via the connecting bracket 1682. In this embodiment, the connecting frame 1682 is provided with a plurality of first connection points 1682a, and the cooling module 221 is provided with a plurality of second connection points 2211. The first connection points 1682a and the second connection points 2211 are used to connect the cooling module 221 and the connecting frame 1682, thereby ensuring a stable connection between the cooling module 221 and the vehicle frame 11. The front bracket 164 is provided with a plurality of second mounting points 1643b, and the cooling module 221 is also provided with a plurality of third connection points 2212. The second mounting points 1643b and the third connection points 2212 are used to connect the cooling module 221 and the front bracket 164. Through the above arrangement, a stable connection of the cooling module 221 can be achieved, thereby enabling the installation of the cooling module 221. The first connection point 1682a and the second connection point 2211 can be connected by bolts or other means; the second mounting point 1643b can be a fixing hole, and the third connection point 2212 can be a fixing post. The fixing post can be inserted into the fixing hole, thereby realizing the snap-fit between the cooling module 221 and the front bracket 164, which facilitates the installation or removal of the cooling module 221 and improves the assemblability of the all-terrain vehicle 100.
[0055] In one implementation, the cooling module 221 includes a radiator 2213, a fan shroud 2214, a cooling fan 2215, an auxiliary water tank 2216, a water inlet 2217, a pipe assembly 2218, and a cable assembly 2219. Along the longitudinal direction of the all-terrain vehicle 100, the radiator 2213 is disposed on the front side of the fan shroud 2214 and fixedly connected to it. The cooling fan 2215 is at least partially disposed within the fan shroud 2214. The cable assembly 2219 connects the cooling fan 2215 and the electrical assembly 18, thereby providing power from the electrical assembly 18 to the cooling fan 2215. The auxiliary water tank 2216 is at least partially disposed on the fan shroud 2214. The water inlet 2217 is at least partially disposed on the radiator 2213. The pipe assembly 2218 connects the auxiliary water tank 2216 and the water inlet 2217.
[0056] Specifically, both the second connection point 2211 and the third connection point 2212 are located on the fan cover 2214. Along the vertical direction of the all-terrain vehicle 100, the second connection point 2211 is located on the upper side of the fan cover 2214, and the third connection point 2212 is located on the lower side of the fan cover 2214. This arrangement allows the mounting point of the cooling module 221 to be located on the fan cover 2214, thereby reducing the deformation of the radiator 2213 due to stress and improving the strength of the cooling module 221. Furthermore, this arrangement simplifies the structure of the radiator 2213 and improves its structural compactness.
[0057] Specifically, a fourth connection point 2214a is provided on the rear side of the fan cover 2214, which is used to install the auxiliary water tank 2216. The fourth connection point 2214a can be connected to the auxiliary water tank 2216 by means of bolts or other fixing methods. Through this arrangement, the mounting point of the auxiliary water tank 2216 can be integrated into the fan cover 2214, saving space for the auxiliary water tank 2216, thereby improving space utilization and making the structure of the all-terrain vehicle 100 more compact.
[0058] Specifically, the water inlet 2217 is located on the upper side of the radiator 2213, and the fourth connection point 2214a is also located on the fan shroud 2214 near the water inlet 2217. This shortens the length of the pipe assembly 2218, saving installation space and improving the utilization rate of the all-terrain vehicle 100. Understandably, the fourth connection point 2214a can be located in other positions on the fan shroud 2214, and its location can be adjusted according to actual needs.
[0059] In this embodiment, the fan cover 2214 is further provided with a first limiting structure 2214b and a second limiting structure 2214c. The first limiting structure 2214b is used to fix the pipe assembly 2218 to prevent wear caused by the shaking of the pipe assembly 2218 during the operation of the all-terrain vehicle 100. The second limiting structure 2214c is used to fix the cable assembly 2219 to prevent wear caused by the shaking of the cable assembly 2219 during the operation of the all-terrain vehicle 100. Through the above-mentioned configuration, the safety and service life of the all-terrain vehicle 100 can be improved.
[0060] Specifically, the first limiting structure 2214b can be disposed on the upper side of the fan cover 2214, thereby fixing the middle position of the pipe assembly 2218 and improving the connection stability of the pipe assembly 2218. In this embodiment, the first limiting structure 2214b can be disposed on the second connection point 2211 near the water inlet 2217, that is, the first limiting structure 2214b can be integrated with the second connection point 2211, thereby reducing the arrangement space of the first limiting structure 2214b and facilitating the processing of the first limiting structure 2214b. The first limiting structure 2214b can be a first slot, which is basically a "C" shaped slot, and the length of the opening of the first slot is less than the diameter of the pipe assembly 2218, thereby achieving an interference fit between the first limiting structure 2214b and the pipe assembly 2218.
[0061] Specifically, one end of the cable assembly 2219 that connects to the cooling fan 2215 is designated as the first end 2219a, and the other end of the cable assembly 2219 is provided with a connector 2219b, which is used to connect to the electrical component 18. A second limiting structure 2214c is disposed between the connector 2219b and the first end 2219a, and is also disposed on the fan cover 2214. This arrangement allows the second limiting structure 2214c to better secure the cable assembly 2219, reducing the swaying of the cable assembly 2219 during the movement of the all-terrain vehicle 100. In this embodiment, the second limiting structure 2214c can be a second slot, which is essentially a "C"-shaped slot, and the length of the opening of the second slot is less than the diameter of the cable assembly 2219, thereby achieving an interference fit between the second limiting structure 2214c and the cable assembly 2219.
[0062] With the above configuration, the mounting points of the cooling module 221, the auxiliary water tank 2216, the fixing points of the pipe assembly 2218, and the fixing points of the cable assembly 2219 can be integrated on the fan cover 2214, thereby saving the arrangement space of the cooling module 221, improving the strength of the cooling module 221, simplifying the structure of the radiator 2213, and effectively reducing the deformation of the radiator 2213.
[0063] In one implementation, the fan cover 2214 includes a first contour and a second contour. The first contour is the outer contour of the fan cover 2214 after removing the second connection point 2211, the third connection point 2212, the fourth connection point 2214a, the first limiting structure 2214b, and the second limiting structure 2214c. The second contour is the outer contour of the fan cover 2214. The all-terrain vehicle 100 includes a projection plane 103 perpendicular to the front-rear direction. The projection of the first contour along the front-rear direction onto the projection plane 103 is the first projection contour, and the projection of the second contour along the front-rear direction onto the projection plane 103 is the second projection contour. The ratio of the area of the first projection contour to the area of the second projection contour is greater than or equal to 0.63 and less than or equal to 1. Specifically, the ratio of the area of the first projection contour to the area of the second projection contour is greater than or equal to 0.72 and less than or equal to 0.99. In this embodiment, the ratio of the area of the first projection contour to the area of the second projection contour is greater than or equal to 0.81 and less than or equal to 0.98. Understandably, the ratio of the area of the first projected contour to the area of the second projected contour is 0.9. Through the above arrangement, the mounting points of the cooling module 221, the auxiliary water tank 2216, the fixing points of the pipe assembly 2218, and the fixing points of the cable assembly 2219 can be integrated onto the fan shroud 2214, while simultaneously making the structure of the fan shroud 2214 more compact, simplifying its structure, reducing its arrangement space, and thus improving the structural compactness of the heat dissipation assembly 22.
[0064] As one implementation, a first connecting pipe 2217a is provided on the water inlet 2217, and a second connecting pipe 2216a is provided on the auxiliary water tank 2216. One end of the pipe assembly 2218 is connected to the first connecting pipe 2217a, and the other end of the pipe assembly 2218 is connected to the second connecting pipe 2216a, thereby achieving a stable connection between the water inlet 2217 and the auxiliary water tank 2216. Specifically, one end of the pipe assembly 2218 and the first connecting pipe 2217a are clamped together, and the other end of the pipe assembly 2218 and the second connecting pipe 2216a are clamped together, thereby facilitating the installation or disassembly of the pipe assembly 2218.
[0065] like Figure 14 and Figure 15As shown, in one implementation, the saddle assembly 15 also includes a storage mechanism 153. The storage mechanism 153 is at least partially disposed on the frame 11 and is used to hold at least a portion of the electrical components 18 and / or other parts of the all-terrain vehicle 100. The storage mechanism 153 includes a first body 1531 and a connecting mechanism 1532. Along the left-right direction of the all-terrain vehicle 100, connecting mechanisms 1532 are provided on both the left and right sides of the first body 1531, and the connecting mechanisms 1532 and the first body 1531 are integrally formed. It is understood that the connecting mechanism 1532 and the first body 1531 can also be connected in other ways. The connecting mechanism 1532 is used to connect to the frame 11, thereby ensuring a stable connection between the frame 11 and the storage mechanism 153. Along the vertical direction of the all-terrain vehicle 100, the connecting mechanism 1532 is disposed at the upper edge of the first body 1531, and the connecting mechanism 1532 is rolled outwards from the first body 1531 to form a rolled edge. The rolled edge forms a space with a substantially circular cross-section for fixed connection with the tubular components of the frame 11. The outer side of the first body 1531 refers to one side of the outer surface of the first body 1531. Specifically, the connecting mechanism 1532 is at least partially disposed on the upper main beam 115. The connecting mechanism 1532 includes a first outer edge 1532a and a second outer edge (not shown in the figure). The first outer edge 1532a is disposed on the first main beam 1151, and the second outer edge is disposed on the second main beam 1152, thereby stably connecting the storage mechanism 153 and the frame 11. In this embodiment, a storage space is formed within the first body 1531, which is used to place at least a portion of the electrical components 18 and / or other parts of the all-terrain vehicle 100.
[0066] As one implementation, the left and right sides of the first main body 1531 are provided with a plurality of first snap-fit connectors 1531a, a plurality of second snap-fit connectors 1531b, and a plurality of third snap-fit connectors 1531c. The plurality of first snap-fit connectors 1531a, second snap-fit connectors 1531b, and third snap-fit connectors 1531c can be used to secure cables and / or pipes on the all-terrain vehicle 100. The plurality of first snap-fit connectors 1531a, second snap-fit connectors 1531b, and third snap-fit connectors 1531c are all disposed on the outer surface of the first main body 1531. Along the vertical direction of the all-terrain vehicle 100, the first latching member 1531a is at least partially disposed above the second latching member 1531b, and the second latching member 1531b is at least partially disposed above the third latching member 1531c, that is, the second latching member 1531b is at least partially disposed between the first latching member 1531a and the third latching member 1531c. Specifically, the first latching member 1531a and the second latching member 1531b form a first fixing space 1531d, which is used to fix the cables and / or pipes of the all-terrain vehicle 100. The second latching member 1531b and the third latching member 1531c form a second fixing space 1531e, which is used to fix the cables and / or pipes of the all-terrain vehicle 100. Through the above arrangement, the fixing positions of the cables and / or pipes of the all-terrain vehicle 100 can be divided into two independent fixing positions, thereby making the arrangement of the cables and / or pipes of the all-terrain vehicle 100 more reasonable and improving the space utilization rate of the all-terrain vehicle 100. Furthermore, through the above arrangement, the additional fixing structures for cables and / or pipes can be reduced, thereby improving the structural compactness of the all-terrain vehicle 100 by integrating the fixing structures for cables and / or pipes. In this embodiment, the first fixing space 1531d and the second fixing space 1531e can be interconnected, or the first fixing space 1531d and the second fixing space 1531e can be set independently.
[0067] In one implementation, the second latching member 1531b includes a first fixing portion 1531f and a second fixing portion 1531g. The first fixing portion 1531f is at least partially disposed on the upper side of the second fixing portion 1531g. The first fixing portion 1531f and the second fixing portion 1531g are integrally formed. The first fixing portion 1531f and the first latching member 1531a form a first fixing space 1531d. The second fixing portion 1531g and the third latching member 1531c form a second fixing space 1531e. The first fixing space 1531d extends substantially along the longitudinal direction of the all-terrain vehicle 100, and the second fixing space 1531e extends substantially along the longitudinal direction of the all-terrain vehicle 100.
[0068] Specifically, the first fixing part 1531f forms a first receiving groove, and the first snap-fit member 1531a is a fixing plate with a first thickness. The first thickness can be adjusted according to actual needs. Along the vertical direction of the all-terrain vehicle 100, the opening of the first receiving groove faces upwards. The all-terrain vehicle 100 includes a projection plane 103 perpendicular to the front-rear direction. The projection of the lowest point of the first snap-fit member 1531a onto the projection plane 103 along the front-rear direction is the ninth projection line, and the projection of the lowest point of the bottom of the first receiving groove onto the projection plane 103 along the front-rear direction is the tenth projection line. The distance between the ninth and tenth projection lines is the first distance, and the maximum width of the cables and / or pipes of the all-terrain vehicle 100 is the second distance. The first distance and the second distance are substantially the same. The maximum width of the cables and / or pipes of the all-terrain vehicle 100 refers to the width perpendicular to the axial direction of the cables and / or pipes. Through the above-described configuration, the cables and / or pipes of the all-terrain vehicle 100 can be better positioned within the first fixed space 1531d, thereby achieving stable connection of the cables and / or pipes of the all-terrain vehicle 100. In this embodiment, the first receiving groove is essentially a semi-cylindrical space, and the cables and / or pipes of the all-terrain vehicle 100 are essentially cylindrical, thus making the fixing of the cables and / or pipes of the all-terrain vehicle 100 more stable.
[0069] Specifically, the second fixing part 1531g forms a second receiving groove, and the third snap-fit part 1531c forms a third receiving groove. Along the vertical direction of the all-terrain vehicle 100, the opening of the second receiving groove faces downwards, and the opening of the third receiving groove faces upwards. The projection of the uppermost end of the bottom of the second receiving groove onto the projection plane 103 in the front-back direction is the eleventh projection line, and the projection of the lowermost end of the bottom of the third receiving groove onto the projection plane 103 in the front-back direction is the twelfth projection line. The distance between the eleventh and twelfth projection lines is the third distance. The third distance is substantially the same as the second distance. Through the above arrangement, the cables and / or pipes of the all-terrain vehicle 100 can be better positioned in the second fixing space 1531e, thereby achieving stable snap-fit of the cables and / or pipes of the all-terrain vehicle 100. In this embodiment, the second receiving groove is substantially a semi-cylindrical space, and the third receiving groove is substantially a semi-cylindrical space; that is, the second fixing space 1531e is substantially a cylindrical space. The cables and / or pipes of the all-terrain vehicle 100 are basically cylindrical, which makes the cables and / or pipes of the all-terrain vehicle 100 more stable.
[0070] In this embodiment, the first snap-fit connector 1531a, the second snap-fit connector 1531b, and the third snap-fit connector 1531c are all provided with reinforcing portions 1531m. The reinforcing portions 1531m are integrally formed with the first snap-fit connector 1531a, the second snap-fit connector 1531b, and the third snap-fit connector 1531c, thereby facilitating the processing of the first main body 1531. The reinforcing portions 1531m are used to strengthen the first snap-fit connectors 1531a, 1531b, and 1531c, thereby improving the structural strength of the first snap-fit connectors 1531a, 1531b, and 1531c, and improving the connection stability of the cables and / or pipes of the all-terrain vehicle 100.
