Too short a grip 2142, the range of lateral movement of the passenger's hands is small, which reduces the gripping comfort. When the grip 2142 is too long, it affects the arrangement of components in the second passenger compartment 112 of the ATV 100, and on the other hand, it is also prone to problems with the grip 2142 not functioning to well hold the hands of the passenger when the ATV 100 is traveling vigorously, resulting in unstable riding of the rear passengers. Further, the length L6 of the grip portion 2142 in the left-right direction is 304mm or more and 373mm or less. Further, the length L6 of the grip portion 2142 in the left-right direction is 320mm or more and 357mm or less. The length L7 of the handrail tube 214 in the left-right direction is 346mm or more and 520mm or less, and the distance L8 between the midpoints of the two handrail tubes 214 is 495mm or more and 745mm or less. The length of the arm tubes 214 is sufficient to meet the gripping needs of the rear passengers, while also taking into account the body size and configuration of the ATV 100. At the same time, the positions of the two armrest tubes 214 also correspond to the positions of the seats in the second passenger compartment 112. Further, the length L7 of the handrail tube 214 in the left-right direction is 389mm or more and 476mm or less, and the distance L8 between the midpoints of the two handrail tubes 214 is 558mm or more and 682mm or less. Further, the length L7 of the handrail tube 214 in the left-right direction is 410mm or more and 455mm or less, and the distance L8 between the midpoints of the two handrail tubes 214 is 589mm or more and 651mm or less. The distance L9 between the two handrail tubes 214 in the left-right direction is 149mm or more and 225mm or less. The spacing between two arm rest tubes 214 may be substantially regarded as the distance between adjacent fixtures 2141 of two arm rest tubes 214. The fixing portion 2141 in the armrest tube 214 functions to restrict lateral movement of the occupant's hands after the occupant grasps the armrest tube 214, in addition to the function of connecting the armrest tube 214 to the cross bar 213. The distance between the two handrail pipes 214 is set in the above range, so that the transverse movement space of the hands of the passengers can be ensured, and the transverse constraint of the handrail pipes 214 to the passengers can be ensured, so that the two passengers in the rear row can be prevented from transverse collision in the driving process. Further, a distance L9 between the two handrail tubes 214 in the left-right direction is 168mm or more and 207mm or less. Further, a distance L9 between the two handrail tubes 214 in the left-right direction is 177mm or more and 197mm or less.

As one embodiment, as shown in fig. 14, the seat assembly 13 includes a seat 131. As shown in fig. 15, the seat 131 includes a seat cushion 1311 and a support frame 1312, a portion of the support frame 1312 being connected to the seat cushion 1311 and for supporting the seat cushion 1311, another portion of the support frame 1312 being connected to the frame 11. Specifically, the support frame 1312 includes a connection portion 1312a for connecting the seat 131 to the frame 11 and a support portion 1312b for supporting the seat cushion 1311, the bottom of the connection portion 1312a being connected to the frame 11, the top of the connection portion 1312a being connected to the support portion 1312b. Specifically, the seat cushion 1311 is connected to the upper side of the support portion 1312b, and the connection portion 1312a is connected to the lower side of the support portion 1312b. The connection portion 1312a and the support portion 1312b may be connected together by welding or fastening, or the connection portion 1312a and the support portion 1312b may be integrally formed. As shown in fig. 16, the connection portion 1312a includes a first connection portion 1312c and a second connection portion 1312d, a pair of second connection portions 1312d are connected to both ends of the first connection portion 1312c, respectively, the first connection portion 1312c is disposed to extend substantially in the left-right direction, and the second connection portion 1312d is disposed to be substantially perpendicular to the left-right direction. Two second connection portions 1312d are respectively disposed at two sides of the first connection portion 1312c, a top portion of the second connection portion 1312d is connected to the supporting portion, and a side or bottom portion of the second connection portion 1312d is connected to two ends of the first connection portion 1312 c. The second connecting portion 1312d may have a structure with a top size larger than a bottom size, so that the second connecting portion 1312d of the structure can reduce occupation of a space under the seat 131 while securing the fixing strength of the seat 131. The first connection portion 1312c may have a groove-shaped structure with a downward opening.

As shown in fig. 17, the dimension L10 of the first connecting portion 1312c in the front-rear direction is 45mm or more and 68mm or less. Further, the dimension L10 of the first connecting portion 1312c in the front-rear direction is 50mm or more and 63mm or less. Further, the dimension L10 of the first connecting portion 1312c in the front-rear direction is 53mm or more and 60mm or less. In this embodiment, the connection portion 1312a has a frame structure provided substantially in the left-right direction, and the connection portion 1312a has a structure with a wide upper portion and a narrow lower portion. The wider top of connecting portion 1312a is connected to supporting portion 1312b, can guarantee to have great area of contact between connecting portion 1312a and the supporting portion 1312b, can guarantee to have great effective connection area between connecting portion 1312a and the supporting portion 1312b, and then guarantee the connection stability between connecting portion 1312a and the supporting portion 1312b. The narrower bottom of the connection portion 1312a is connected to the frame 11, reducing the space occupied by the connection portion 1312a while ensuring the connection strength and connection stability. Specifically, the provision of the connection portion 1312a can reduce the space occupation rate below the seat 131, and a certain internal space can be left below the seat 131. The interior space may be further used to provide a storage space, provide a corresponding mounting space for other components of the ATV 100, and provide a more comfortable foot space for a passenger behind the seat 131. Accordingly, the frame 11 includes therein a seat mounting beam 215 (as shown in fig. 11) for connecting the seat 131, the seat mounting beam 215 extending substantially in the left-right direction. As shown in fig. 18, when the seat 131 is mounted, the connection portion 1312a in the seat 131 is fitted over the outside of the seat mounting beam 215 while the connection portion 1312a is connected to the seat mounting beam 215. Specifically, a first connecting portion 1312c having a groove-like structure in the connecting portion 1312a is fitted over the outside of the seat mounting beam 215, and then the first connecting portion 1312c is connected to the seat mounting beam 215 by a fastener extending in the front-rear direction. Because the bottom of the connecting portion 1312a is narrower, the seat 131 can be better connected to the frame 11 by sleeving and fastening, so as to enhance the connection strength between the seat 131 and the frame 11. In the present embodiment, the seat mounting beam 215 includes only one cross member disposed in the left-right direction, and the seat mounting beam 215 itself has a small space in the front-rear direction. The seat mounting beam 215 and the connecting portion 1312a are mutually matched, so that the space below the seat 131 can be better saved, more space in the vehicle is provided for the all-terrain vehicle 100, the placement of other devices is facilitated, and more riding space is provided for passengers. The first connection portion 1312c has a first connection portion projection in the first plane in the up-down direction, and the seat cushion 131 has a seat cushion projection in the first plane, the first connection portion projection being located behind the geometric center of the seat cushion projection. The connection 1312a has a connection projection in a first plane, the first connection projection being located behind the geometric center of the connection projection. Based on the analysis of the load applied to the passenger seated in the seat assembly 13, the weight of the passenger is mostly concentrated at a position behind the geometric center of the seat assembly 13, and the first connection portion 1312c is located near the rear side of the seat assembly 13, so that the first connection portion 1312c can better perform the function of carrying the passenger, and the seating safety of the passenger can be ensured. The seat 131 in the present embodiment may be a seat provided only in the first passenger compartment 111, a seat provided only in the second passenger compartment 112, or a seat provided in both the first passenger compartment 111 and the second passenger compartment 112. The seat 131 in the present embodiment may be a driver seat or a passenger seat.

As an embodiment, as shown in fig. 19, the frame 11 includes a first passenger compartment 111 (i.e., a cockpit) surrounded by a first frame portion of the frame 11, and the frame 11 further includes a module assembly 218, as shown in fig. 20, formed of a second frame portion of the frame 11. The module assembly 218 is coupled to the rear of the first passenger compartment 111 to form the second passenger compartment 112 (i.e., the passenger compartment). The module assembly 218 includes diagonal beams 2181, struts 2182, stringers 2183, and a floor frame 2184. Specifically, only one module assembly 218 may be included in frame 11, with module assembly 218 being connected to the rear of first passenger compartment 111, and the structure including one first passenger compartment 111 and one second passenger compartment 112 being formed in ATV 100. The frame 11 may also include a plurality of module assemblies 218, where the plurality of module assemblies 218 are connected in series and then connected to the first passenger compartment 111, and a structure including one first passenger compartment 111 and a plurality of second passenger compartments 112 is formed in the ATV 100. The provision of the module assembly 218 can facilitate expansion of the model of the ATV 100 for manufacturing ATVs having a second passenger compartment 112 or a plurality of second passenger compartment 112 configurations. The frame 11 further includes front and rear side members 118 provided on both sides, a portion of the front and rear side members 118 being connected to a side of the first passenger compartment 111, and another portion of the front and rear side members 118 being connected to a side of the module assembly. Providing the front and rear stringers 118 can enhance the strength of the connection between the module assembly 218 and the first passenger compartment 111, i.e., the connection between the first passenger compartment 111 and the second passenger compartment 112. In addition, most of the components in the module assembly 218 borrow components in the first passenger compartment 111. That is, in this embodiment, most of the components in the second passenger compartment 112 borrow the components in the first passenger compartment 111, and at least some of the components in the second passenger compartment 112 are identical to the corresponding components in the first passenger compartment 111. Specifically, as shown in fig. 19, the second diagonal beam 1121, the second upright 1122, the tail rail 1123, and the rear floor frame 1124 in the second passenger compartment 112 correspond to the first diagonal beam 1111, the first upright 1112, the middle rail 113, and the front floor frame 1113, respectively, in the first passenger compartment 111. That is, the trailing stringers 1123 in the second passenger compartment 112 are substantially identical to the center stringers 113, the second uprights 1122 in the second passenger compartment 112 are substantially identical to the first uprights 1112 in the first passenger compartment 111, the second diagonal girders 1121 in the second passenger compartment 112 are substantially identical to the first diagonal girders 1111 in the first passenger compartment 111, and the rear floor frames 1124 in the second passenger compartment 112 are substantially identical to the front floor frames 1113 in the first passenger compartment 111. Most of the components in the second passenger compartment 112 are borrowed from the components in the first passenger compartment 111, so that the development process of most of the components in the second passenger compartment 112 can be omitted, and the corresponding development cost can be saved. While also reducing the cost of manufacturing the same components in the first passenger compartment 111. Furthermore, such an arrangement is essentially a modular arrangement. Because of the modular arrangement, the passenger compartment is substantially free of significant design, and the application module assembly 218 is capable of completing the design and manufacture of a corresponding vehicle model, which can greatly reduce the design and manufacturing costs of the ATV 100.

As an embodiment, as shown in fig. 21, the middle longitudinal beam 113 is provided with a buffer member 125, and the buffer member 125 is provided on the surface of the middle longitudinal beam 113 along the extending direction of the middle longitudinal beam 113. When a rear passenger gets on or off the all-terrain vehicle 100, the knees and legs of the passenger are likely to collide with the center stringers 113, and the knees and legs of the passenger are likely to be injured. The buffer member 125 is disposed on the middle longitudinal beam 113, so that injury caused by collision between knees or legs of a passenger and the middle longitudinal beam 113 can be reduced, and safety of the passenger can be protected. The hardness of the buffer 125 is 10HA or more and 20HA or less. The hardness setting of the cushioning members 125 can ensure that the cushioning members 125 themselves do not injure the passengers, and also ensure that the cushioning members 125 provide good cushioning between the passengers and the center stringers 113. The thickness of the buffer 125 is 3mm or more. When the thickness of the cushioning member 125 is 3mm or more, the cushioning member 125 can provide sufficient cushioning for the knees or legs of the occupant and also can prevent the knees or legs of the occupant from colliding with the center longitudinal beam 113. As shown in fig. 22, a distance H1 between the highest point of the buffer 125 and the foot pedal 124 is 420mm or more and 640mm or less. On a second plane perpendicular to the left-right direction, the buffer 125 has a buffer projection on the second plane in the left-right direction, and a length H2 of the buffer projection in the up-down direction is 200mm or more and 600mm or less. The buffer piece 125 is arranged on the surface of the middle longitudinal beam 113, so that the buffer piece 125 can basically cover the knees and legs of passengers, the buffer effect of the buffer piece 125 can be met, and the knees and legs of the passengers are prevented from being injured.

It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
