[0049] Reference below Figure 1-Figure 13 The frame 1000 according to the embodiment of the present invention is described. The frame 1000 is applied to an all-terrain vehicle, which is a vehicle that can travel on any terrain and can travel freely on terrains where ordinary vehicles are difficult to maneuver. It is commonly known as a beach vehicle in China.

[0050] like Figure 1-Figure 3 As shown, the frame 1000 of the all-terrain vehicle according to the embodiment of the present invention may include: a main frame 100, a front axle mounting device 200, a first sub-frame 300, a second sub-frame 400, a third sub-frame 600 and a roof frame 500, wherein the main frame 100 constitutes the main structure of the frame 1000, and a cockpit 120 and a power compartment 130 may be formed in the main frame 100. The cockpit 120 is for the driver and passengers to sit in, and a driver's seat and a passenger seat may be configured therein. The power compartment 130 is used to install and place a power device, and the power device may include an engine and / or an electric motor. According to different types of power devices, the all-terrain vehicle can be divided into pure oil, pure electric and hybrid drive forms.

[0051] like Figure 1-Figure 3As shown, the front axle mounting device 200, the first sub-frame 300, the second sub-frame 400, the third sub-frame 600 and the roof frame 500 are all separate structures from the main frame 100, that is, the front axle mounting device 200, the first sub-frame 300, the second sub-frame 400, the third sub-frame 600 and the roof frame 500 are not integrally welded with the main frame 100, and the above components are all installed and fixed at different positions of the main frame 100 to play different functional roles.

[0052] The vehicle frame 1000 of the embodiment of the present invention is non-integrally welded, which can make the vehicle frame 1000 easy to manufacture, increase the flexibility of the layout of the vehicle frame 1000, and facilitate the installation and fixation of various functional components on the vehicle frame 1000.

[0053] like Figure 3 and Figure 4 As shown, the front axle mounting device 200 is used to install the front axle 5000, and the front axle mounting device 200 is fixed to the lower side of the front end of the main frame 100. Conventional all-terrain vehicles generally use pipes to form a mounting structure for the front axle on the front side of the frame. The mounting structure needs to install the front axle and the suspension device located on the front side. However, due to the large size of the suspension device, the pipe cannot extend to the front side of the all-terrain vehicle, resulting in greater difficulty in installing the front axle and the suspension device. The front axle mounting device 200 of the present invention is set separately, which can effectively adapt to the front axle 5000 and the suspension device, thereby reducing the difficulty of installing the front axle 5000 and the suspension device, and the installation reliability of the front axle 5000 and the suspension device is higher.

[0054] like Figure 3 , Figure 4 and Figure 6 As shown, the first sub-frame 300 is mounted on the upper front side of the main frame 100, and the first sub-frame 300 is located above the front axle mounting device 200. The first sub-frame 300, the front axle mounting device 200 and the front part of the main frame 100 form a component accommodating space. The first sub-frame 300 mainly supports and installs components. The front part of the shell cover of the all-terrain vehicle can be set on the first sub-frame 300, and the first sub-frame 300 can play a role in installation and fixing. Moreover, as shown in FIG. Figure 7 and Fig. 9 As shown, the component accommodating space can be used to accommodate the radiator 2000 , so that the first sub-frame 300 can effectively protect the radiator 2000 .

[0055] By configuring the first sub-frame 300 to be an integral frame 1000 structure, the structural rigidity and strength of the first sub-frame 300 can be improved, the installation and fixation of various components can be facilitated, and the structural strength of the frame 1000 can be further improved. Moreover, due to the improvement of its own structural strength, the vibration of various components installed thereon is also reduced accordingly, which can further reduce the failure rate of various components.

[0056] like Figure 1 and Figure 2 As shown, the lower end of the second sub-frame 400 is mounted on the main frame 100, and the second sub-frame 400 is located in front of the cockpit 120, and the lower end of the second sub-frame 400 is located in front of the cockpit 120, and the rear upper end of the first sub-frame 300 can be mounted on the second sub-frame 400. A front shock absorber of a suspension device can be arranged at the front end of the second sub-frame 400, and the front shock absorber is provided with a plurality of mounting points to be connected and fixed to the main frame 100.

[0057] It should be noted that the surfaces of the main frame 100 and the second sub-frame 400 both need to go through a painting step. Since the second sub-frame 400 and the main frame 100 are independent structures, when painting the all-terrain vehicle, the main frame 100 and the second sub-frame 400 can be painted separately, which effectively reduces the difficulty of painting. In addition, since part of the second sub-frame 400 is exposed from the shell of the all-terrain vehicle, in order to better protect the second sub-frame 400, the paint layer on its surface is different from the paint layer of the main frame 100, which reduces the cost of painting the main frame 100.

[0058] like Fig.12 and Fig.13 As shown, the main frame 100 is formed with a fuel tank compartment 150 at the inner side of the front part of the cockpit 120, the upper part of the fuel tank compartment 150 is open, the third sub-frame 600 and the main frame 100 are separate structures, and the third sub-frame 600 is installed at the upper part of the fuel tank compartment 150. That is, the all-terrain vehicle of the present invention sets the fuel tank 7000 in the cockpit 120, and sets the fuel tank compartment 150 in the front part of the cockpit 120 (i.e., the instrument installation area), so that the space in the cockpit 120 can be reasonably utilized, and the fuel tank 7000 and the power device can be separated, so that the heat generated by the power device at work can be prevented from being transferred to the fuel tank 7000, and the safety of the use of the fuel tank 7000 can be ensured. In addition, by setting the fuel tank compartment 150 in the cockpit 120, the structural complexity of the frame 1000 can be reduced, and the difficulty of arranging the fuel tank 7000 can be reduced, and the weight of the whole all-terrain vehicle can be further made uniform.

[0059] Among them, the provision of the third sub-frame 600 can facilitate the installation and disassembly of the fuel tank 7000. For example, after the fuel tank 7000 is placed in the fuel tank compartment 150, the third sub-frame 600 can be installed on the main frame 100, which can also effectively ensure the installation reliability of the fuel tank 7000.

[0060] like Figure 1 and Figure 2 As shown, the roof frame 500 is arranged above the main frame 100 and the second sub-frame 400. Specifically, the roof frame 500 is mainly installed above the cockpit 120 and the power compartment 130. The front end of the roof frame 500 is installed on the upper part of the second sub-frame 400, and the rear part of the roof frame 500 is installed on the main frame 100, and the rear part of the roof frame 500 is located at the rear side of the cockpit 120. The roof frame 500 can protect the driver and passengers. When the all-terrain vehicle rolls over, the roof frame 500 can first contact and collide with the ground, so that the driver and passengers can avoid direct contact and collision with the ground, and the safety of the driver and passengers can be ensured.

[0061] Therefore, according to the frame 1000 of the all-terrain vehicle according to the embodiment of the present invention, by integrating various sub-frames 1000 and front axle mounting devices 200 on the main frame 100, the frame 1000 can be easily installed and arranged, the difficulty of installing components of the frame 1000 can be reduced, the manufacturing cost of the frame 1000 can be reduced, and the structural reliability of the frame 1000 can be ensured.

[0062] According to an optional embodiment of the present invention, Figure 3 and Figure 4 As shown, the front axle mounting device 200 can be a sheet metal frame. The interior of the sheet metal frame can be formed as a front axle mounting space, that is, the front axle 5000 is installed inside the sheet metal frame, and the components of the suspension device can be installed on the outside of the sheet metal frame. A plurality of corresponding mounting positions can be formed on the sheet metal frame, so that the front axle 5000 and the suspension device can be integrated and installed on the sheet metal frame. Moreover, the sheet metal frame has high structural strength, which can effectively ensure the reliability of the front axle 5000 and the suspension device. The sheet metal frame is easy to arrange, and it can adapt to the front space of the main frame 100, so that the front axle 5000 and the suspension device can be reasonably arranged.

[0063] Specifically, Figure 4As shown, the front axle mounting device 200 includes: a front sheet metal part 201, a left sheet metal part 202, a right sheet metal part 204, an upper sheet metal part 206 and a lower sheet metal part 207 which are connected in sequence according to orientation, that is, the left sheet metal part 202 and the right sheet metal part 204 are arranged opposite to each other left and right, and the upper sheet metal part 206 and the lower sheet metal part 207 are arranged opposite to each other up and down, and the front sheet metal part 201 is connected to the front sides of the left sheet metal part 202, the right sheet metal part 204, the upper sheet metal part 206 and the lower sheet metal part 207, so as to form a sheet metal frame, and the front sheet metal part 201, the left sheet metal part 202, the right sheet metal part 204, the upper sheet metal part 206 and the lower sheet metal part 207 jointly define the front axle mounting space.

[0064] The front axle mounting device 200 may also include a rear sheet metal part 210, which is connected to the rear sides of the left sheet metal part 202, the right sheet metal part 204, the upper sheet metal part 206 and the lower sheet metal part 207. The rear end of the lower sheet metal part 207 is connected to the lower front end of the main frame 100, so that the installation reliability of the front axle mounting device 200 and the main frame 100 can be ensured, wherein the rear ends of the left sheet metal part 202 and the right sheet metal part 204 can also be installed on the lower front end of the main frame 100.

[0065] like Figure 4 and Figure 6 As shown, the left sheet metal part 202 and the right sheet metal part 204 are formed with clearance holes, that is, the left sheet metal part 202 is provided with a left clearance hole 203, and the right sheet metal part 204 is provided with a right clearance hole 205. The rear end of the front axle 5000 needs to be connected to the transmission of the transmission system, and the left and right ends of the front axle 5000 need to be connected to the corresponding half shafts. The left clearance hole 203 is used to avoid the left half shaft, and the right clearance hole 205 is used to avoid the right half shaft. The bottom edges of the left clearance hole 203 and the right clearance hole 205 can be provided with arc edges, and the arc edges can be used to avoid the corresponding half shafts.

[0066] The left sheet metal 202 and the right sheet metal 204 may be provided with mounting holes below the corresponding clearance holes, and the front axle 5000 may be provided with mounting holes below, so that the left sheet metal 202 and the right sheet metal 204 can jointly ensure the installation reliability of the front axle 5000. Among them, the lower sheet metal 207 may also be provided with a corresponding installation position for installing the front axle 5000.

[0067] Furthermore, if Figure 3As shown, the main frame 100 includes: a first front cross beam 101, which is arranged at the lower side of the front end of the main frame 100, and the rear of the lower sheet metal 207, the lower rear end of the left sheet metal 202, and the lower rear end of the right sheet metal 204 are all connected to the first front cross beam 101. It can be understood that the first front cross beam 101 of the main frame 100 is mainly used to install and connect the front axle mounting device 200, and the left sheet metal 202 and the right sheet metal 204 can also be connected to the first front cross beam 101 of the main frame 100, which can further improve the connection reliability between the front axle mounting device 200 and the main frame 100, and can further improve the structural reliability of the frame 100. Among them, the first front cross beam 101 and the lower sheet metal 207 are welded and fixed, the first front cross beam 101 and the left sheet metal 202 are welded and fixed, and the first front cross beam 101 and the right sheet metal 204 are welded and fixed.

[0068] Specifically, Figure 3 As shown, the main frame 100 may further include: a second front cross beam 102, a first front vertical beam 103 and a first inclined beam 104. The second front cross beam 102 is arranged directly behind the first front cross beam 101. The lateral length of the second front cross beam 102 may be greater than the lateral length of the first front cross beam 101. The lateral length of the first front cross beam 101 is substantially the same as the lateral length of the front axle mounting device 200. The first front cross beam 101 arranged in this way may effectively match the front axle mounting device 200, and may reduce the size of the front portion of the frame 1000, and may facilitate the arrangement of surrounding covers.

[0069] like Figure 4 As shown, a first front longitudinal beam 105 is connected between the first front cross beam 101 and the second front cross beam 102 , and the first front longitudinal beam 105 can effectively connect the first front cross beam 101 and the second front cross beam 102 , thereby ensuring the connection reliability of the first front cross beam 101 and the second front cross beam 102 .

[0070] like Figure 3 As shown, the first front vertical beam 103 is connected to the second front cross beam 102, and the first front vertical beam 103 extends upward, and the first inclined beam 104 is obliquely connected between the first front vertical beam 103 and the first front cross beam 101. It should be noted that the extension direction of the first front vertical beam 103 is generally the up-down direction, which may be a direction other than the up-down direction. The obliquely arranged first inclined beam 104 can effectively connect the first front cross beam 101 and the first front vertical beam 103, so that the first front cross beam 101 can withstand forces in all directions, and the reliability of the first front cross beam 101 can be further improved, thereby improving the connection reliability between the front axle mounting device 200 and the main frame 100.

[0071] Among them, Figure 5As shown, a steering gear mounting bracket 117 is provided on the first front vertical beam 103, the steering gear 3200 is mounted on the steering gear mounting bracket 117, and the front balance bar 3300 of the suspension device can also be mounted on the steering gear mounting bracket 117. The steering mounting bracket 117 provided in this way can be installed with two different components, and the integration is high.

[0072] Also, if Figure 3 and Figure 4 As shown, the main frame 100 may further include: two second inclined beams 106, two first front vertical beams 103, two first inclined beams 104, and the two first inclined beams 104 are respectively connected to the two ends of the first front cross beam 101, so that the two first inclined beams 104 can effectively ensure the lateral stability of the first front cross beam 101. The two second inclined beams 106 are respectively arranged above the two first inclined beams 104, and the connection between the rear part of the upper sheet metal 206 and the upper end of the rear part of the left sheet metal 202 is connected to the front lower end of one second inclined beam 106, and the connection between the rear part of the upper sheet metal 206 and the upper end of the rear part of the right sheet metal 204 is connected to the front lower end of another second inclined beam 106. In other words, the two second inclined beams 106 are connected to the rear upper part of the front axle mounting device 200, that is, the connection between the upper sheet metal 206 and the rear end of the left sheet metal 202, and the connection between the lower sheet metal 207 and the rear end of the right sheet metal 204. By providing two second inclined beams 106 , the connection reliability between the front axle mounting device 200 and the main frame 100 can be further improved, and the structural reliability of the frame 1000 can be further improved.

[0073] Among them, combined Figure 4-Figure 6 As shown, a rocker rear lower end installation space is defined between the first front cross beam 101 and the second front cross beam 102, and a rocker rear mounting frame 107 is provided at the rear of the first front cross beam 101. There are two rockers, namely, a front upper rocker arm 3000 and a front lower rocker arm 3100, which are arranged at intervals up and down, the front upper rocker arm 3000 has two inner mounting ends, and the front lower rocker arm 3100 has two inner mounting ends.

[0082] Specifically, Fig. 9 As shown, the first connection portion 302 includes: a first connection segment 307, a second connection segment 308 and a third connection segment 309, the second connection segment 308 is connected between the first connection segment 307 and the third connection segment 309, and the second connection segment 308 is bent at a predetermined angle relative to the first connection segment 307 and the third connection segment 309, the lower end of the first connection segment 307 is connected to the first mounting portion 301, and the upper end of the third connection segment 309 is connected to the second mounting portion 303. By setting the first connection portion 302 into three segments, the heat sink 2000 can be effectively avoided, and the outer side of the heat sink 2000 can be effectively protected. Moreover, the first connection portion 302 set in this way can effectively connect the first mounting portion 301 and the second mounting portion 303.

[0083] Alternatively, if Fig. 9 and Fig.10 As shown, there may be two first connecting parts 302, and a second connecting rod 313 extending laterally is connected between the two first connecting parts 302. The provision of the second connecting rod 313 can play a role in strengthening the connection strength of the two first connecting parts 302, thereby improving the structural strength of the first sub-frame 300, and further improving the structural reliability of the frame 1000.

[0084] Among them, Fig. 9 and Fig.10 As shown, a third mounting bracket 314 extending toward the front is provided on the second connecting rod 313, and the third mounting bracket 314 is used to mount the headlight cover. The third mounting bracket 314 can play the role of mounting and fixing the headlight cover, so that the first sub-frame 300 can be integrated with multiple components, multiple components can have reasonable installation positions, and the integration capability of the frame 1000 can be improved.

[0085] Also, if Fig. 9 and Fig.10 As shown, the outer sides of the two first connecting parts 302 are respectively connected with third connecting rods 317, and the ends of the third connecting rods 317 are provided with fourth mounting brackets 315 for connecting the cover. The third connecting rods 317 can protect the radiator 2000, and the fourth mounting brackets 315 can install the cover, which can ensure the integrity of the all-terrain vehicle and improve the structural reliability of the all-terrain vehicle.

The second mounting portion 303 formed of sheet metal is light in weight and has high structural reliability, and the second mounting portion 303 can be attached to the surface of the connecting portion, which can ensure the installation reliability of the second mounting portion 303. The fastener can pass through the corresponding mounting bushing 316 to fix the second mounting portion 303 on the second sub-frame 400, so that the overall structural integrity of the frame 1000 can be ensured.

[0087] According to an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the second sub-frame 400 can be detachably mounted on the main frame 100. While ensuring the strength of the all-terrain vehicle and the safety during operation, the second sub-frame 400 is detachably connected to the main frame 100 through fasteners, so that the second sub-frame 400 is easy to install and fix, and can also further facilitate the subsequent maintenance of the frame 1000.

[0088] like Figure 1 and Figure 2 As shown, the second sub-frame 400 includes: a third front cross beam 401 and two second front vertical beams 402, the third front cross beam 401 is connected between the two second front vertical beams 402, and the two second front vertical beams 402 extend downward, and the lower ends of the two second front vertical beams 402 are respectively detachably mounted on the main frame 100. The third front cross beam 401 and the two second front vertical beams 402 are welded as a whole, and such an arrangement can improve the rigidity of the second sub-frame 400.

[0089] Among them, the two second front vertical beams 402 extend downward and toward the inner side of the cockpit 120. The second front vertical beams 402 arranged in this way will not interfere with other structures, making the structure of the frame 1000 more reasonable and compact. Further, mounting plates are respectively arranged on both sides of the lower ends of the two second front vertical beams 402, and mounting holes are respectively arranged on the mounting plates and the main frame 100. Two mounting holes can be correspondingly arranged on the mounting plate, and two mounting holes are also correspondingly arranged on the main frame 100, so that two fasteners can pass through the mounting holes on the mounting plate and the main frame 100, so that the mounting plate can be firmly fixed on the main frame 100, thereby ensuring the installation reliability of the second sub-frame 400 on the main frame 100.

[0090] Specifically, Figure 1-Figure 2 As shown, the main frame 100 includes a chassis 140 and a side oblique beam 108, two first front vertical beams 103, and the two first front vertical beams 103 are arranged in the middle of the front part of the chassis 140, the side oblique beam 108 is obliquely connected to the upper part of the first front vertical beam 103 and the side of the chassis 140, and the lower ends of the second front vertical beams 402 are detachably mounted on the side oblique beams 108. The chassis 140 is arranged at the lower end of the main frame 100, and is used to support the frame 1000 and transmit power. The driver's seat in the cockpit 120 is fixed on the chassis 140. The lower end of the side oblique beam 108 is welded to the side of the chassis 140 and the bottom of the cockpit 120, and the upper end of the side oblique beam 108 is welded to the upper part of the first front vertical beam 103, so that the frame 1000 arranged in this way is stable and reliable.

[0091] Among them, mounting plates are provided on both sides of the lower end of the second front vertical beam 402, and the mounting plates are detachably mounted in the middle of the side oblique beam 108 through fasteners. Such a structure allows the second sub-frame 400 to be flexibly disassembled from the main frame 100, ensuring the flexibility of painting and coloring the frame 1000.

[0092] Furthermore, if Figure 2As shown, the second sub-frame 400 includes a lower connector 403, which is connected to the lower side of the third front cross beam 401 and is located between the two second front vertical beams 402. The lower connector 403 can be detachably mounted on the upper end of the first front vertical beam 103. The second sub-frame 400 is provided with a lower connector 403, which is welded to the third front cross beam 401 and the two second front vertical beams 402 to form a whole. The second sub-frame 400 structure is more stable and reliable, ensuring the safety of the frame 1000. The lower connecting head 403 of the second sub-frame 400 cooperates with the mounting plate on the second front vertical beam 402 and is detachably mounted on the main frame 100. The frame 1000 configured in this way can achieve detachable installation and fixation in multiple places, which can make the frame 1000 more stable, and can be flexibly disassembled when the frame 1000 is painted and colored, and can effectively reduce the difficulty of multi-color painting of the frame 1000.

[0093] Specifically, the lower connecting head 403 and the upper end of the first front vertical beam 103 are both formed with installation spaces that avoid each other, that is, the lower connecting head 403 is a non-circular connecting head, and the upper end of the first front vertical beam 103 is also a non-circular connecting head. The two are matched together to form a full-circular connection structure, which can ensure the connection reliability between the lower connecting head 403 and the upper end of the first front vertical beam 103.

[0094] In addition, the lower connector 403 and the upper end of the first front vertical beam 103 are also provided with guide bevels, respectively. The guide bevels are arc-shaped surfaces, which can effectively improve the wear resistance of the lower connector 403 and the upper end of the first front vertical beam 103, and the guide bevels can effectively guide the assembly between the lower connector 403 and the first front vertical beam 103, which can reduce the difficulty of assembly and improve the assembly efficiency. In addition, the guide bevels are provided with mounting holes. After the lower connector 403 is matched with the guide bevels of the first front vertical beam 103, the lower connector 403 and the first front vertical beam 103 are further fixed together by fasteners. The multiple matching guide bevels provided in this way effectively improve the matching accuracy and increase the structural strength of the frame 1000.

[0095] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front end of the ceiling frame 500 can be detachably mounted at the connection between the third front cross beam 401 and the second front vertical beam 402. The ceiling frame 500 can be detachably mounted on the second sub-frame 400, so that the frame 1000 can be flexibly assembled and disassembled, and the installation reliability of the ceiling frame 500 can be ensured.

[0096] like Figure 1-Figure 2As shown, the second sub-frame 400 further includes a rear connector 404, which is disposed at the connection between the third front cross beam 401 and the second front vertical beam 402, and the rear connector 404 and the front end of the roof frame 500 can be detachably mounted. The rear connector 404 and the front end of the roof frame 500 are both provided with mounting holes, and the rear connector 404 and the roof frame 500 are fixedly connected by fasteners.

[0097] Furthermore, the front ends of the rear connector 404 and the ceiling frame 500 are formed with installation spaces for avoiding each other, and the front ends of the rear connector 404 and the ceiling frame 500 are also provided with guiding inclined surfaces. There are two rear connectors 404, and both rear connectors 404 are provided with installation holes. The front end of the ceiling frame 500 located on the right side of the frame 1000 is provided with an installation hole for matching the rear connector 404 of the second sub-frame 400 on the right side, and the front end of the ceiling frame 500 on the right side of the frame 1000 is formed with an avoidance space for matching the rear connector 404 of the second sub-frame 400 on the right side. During installation, the rear connector 404 is placed in the avoidance space at the front end of the ceiling frame 500 on the right side of the frame 1000, and then the fastener is placed in the installation hole, and the fastener is screwed to complete the fixed connection between the second sub-frame 400 and the ceiling frame 500. In addition, the rear connection head 404 of the second sub-frame 400 on the right side and the front end of the roof frame 500 on the right side of the frame 1000 are both provided with guiding inclined surfaces, and the two guiding inclined surfaces cooperate with each other. It can be understood that the front end of the roof frame 500 on the left side of the frame 1000 and the rear connection head 404 of the second sub-frame 400 on the left side of the frame 1000 are also provided with such a connection structure. The frame 1000 provided in this way can effectively improve its stability through multiple connection cooperation, ensuring the stability and reliability of the all-terrain vehicle.

[0098] Specifically, Figure 2 As shown, the roof frame 500 includes a roof body 501 and a lower connecting rod 502, the front end of the roof body 501 is mounted on the upper part of the second sub-frame 400, the lower connecting rod 502 is connected to the rear part of the roof body 501 and extends downward, the lower end of the lower connecting rod 502 is mounted on the main frame 100, and the lower end of the lower connecting rod 502 is located at the rear side of the cockpit 120. The roof frame 500 is connected to the second sub-frame 400 and the main frame 100 respectively. When the main frame 100, the second sub-frame 400 and the roof frame 500 are all fixedly connected, the main frame 100, the second sub-frame 400 and the roof frame 500 form a complete frame 1000 of the all-terrain vehicle.

[0099] like Figure 3As shown, the main frame 100 further includes a power compartment 130, which is arranged at the rear side of the cockpit 120. The power compartment 130 is the rear end structure of the main frame 100. An upper connecting beam 114 is arranged above the power compartment 130, and the upper connecting beam 114 extends upward, and the upper end of the upper connecting beam 114 and the lower end of the lower connecting rod 502 can be detachably mounted. Among them, the engine is arranged in the power compartment 130, and the power compartment 130 is arranged at the rear side of the cockpit 120, which can shorten the distance of power transmission, increase the space of the cockpit 120, and improve the driving comfort of the driver. The lower connecting rod 502 of the roof frame 500 extending downward is detachably connected to the upper connecting rod 114 of the main frame 100 extending upward. The upper connecting rod 114 and the lower connecting rod 502 arranged in this way will not interfere with other structures, making the structure of the frame 1000 more reasonable and compact, and making the roof frame 500 flexibly disassembled, so that the roof frame 500 can be painted with a separate color, which can further achieve the diversity of the appearance of the frame 1000, and the upper connecting rod 114 and the lower connecting rod 502 arranged in this way can ensure the installation reliability between the main frame 100 and the roof frame 500. Among them, the upper connecting beam 114 and the lower connecting rod 502 are both extended obliquely.

[0100] In some embodiments of the present invention, a protective paint layer is formed on the surface of the second sub-frame 400, and the protective paint layer can protect the second sub-frame 400 and prevent the second sub-frame 400 from being corroded by the external environment, thereby extending the service life of the second sub-frame 400 and effectively improving the stability and safety of the frame 1000.

[0101] According to an optional embodiment of the present invention, Fig.11 As shown, the ceiling frame 500 may include: a split first side top bar 503, a second side top bar 504 and a connecting body 505, the first side top bar 503 and the second side top bar 504 are arranged at intervals on the left and right, the left side of the connecting body 505 is connected to the first side top bar 503, and the right side of the connecting body 505 is connected to the second side top bar 504. In other words, the ceiling frame 500 may be mainly composed of three parts, namely, two side top bars and a connecting body 505. The ceiling frame 500 thus arranged has a simple structure, and because it is a split structure, it can be easily transported, the transportation cost can be reduced, and the reliability after fixed connection can also be guaranteed.

[0102] Alternatively, if Figure 1 and Fig.11As shown, the left side of the connecting body 505 can be detachably connected to the first side top rod 503, and the right side of the connecting body 505 can be detachably connected to the second side top rod 504. The detachable connection method can facilitate the installation and removal of the roof frame 500, and can also be easily replaced after the structure is damaged, without having to replace the roof frame 500 as a whole, which can further reduce the maintenance and replacement costs of the all-terrain vehicle.

[0103] Among them, Figure 1 and Fig.11 As shown, at least two first connectors 506 and at least two second connectors 507 are respectively provided on the left and right sides of the connection body 505, at least two third connectors 508 are provided on the first side top rod 503, and at least two fourth connectors 509 are provided on the second side top rod 504. The at least two first connectors 506 are detachably connected to the at least two third connectors 508, and the at least two second connectors 507 are detachably connected to the at least two fourth connectors 509. By providing a plurality of connectors between the connection body 505 and the first side top rod 503, and providing a plurality of connectors between the connection body 505 and the second side top rod 504, the connectors can effectively play a connecting role, which can reduce the difficulty of installing the connection body 505 and the side top rods on both sides, and can ensure the installation reliability of the ceiling frame 500.

[0104] Furthermore, there is an escape space between the first connector 506 and the corresponding third connector 508, and between the second connector 507 and the corresponding fourth connector 509. That is, the first connector 506, the second connector 507, the third connector 508 and the fourth connector 509 are all non-full-circle connectors, and the two corresponding connectors are arranged relative to each other to form a full-circle connection structure. The connection structure arranged in this way can effectively connect the connection body 505 and the side top rod, and can ensure the structural reliability of the ceiling frame 500.

[0105] In addition, a guiding inclined surface is provided between the first connector 506 and the corresponding third connector 508, and between the second connector 507 and the corresponding fourth connector 509. The guiding inclined surface can play a role in guiding installation, which can reduce the installation difficulty of the corresponding connector and make the matching surfaces of the two corresponding connectors more smoothly. The guiding inclined surface can be a guiding inclined plane or a guiding inclined arc surface.

[0106] Specifically, Fig.11As shown, the connecting body 505 includes: a first transverse top bar 510, a second transverse top bar 511 and a first longitudinal top bar 512, the first transverse top bar 510 is located in front of the second transverse top bar 511, the first longitudinal top bar 512 is connected between the first transverse top bar 510 and the second transverse top bar 511, and the left and right ends of the first transverse top bar 510 and the second transverse top bar 511 are respectively provided with a third connector 508 and a fourth connector 509. It can be understood that the connecting body 505 thus provided is generally in an I-shape, so that the structural strength of the connecting body 505 is high, and the first transverse top bar 510 and the second transverse top bar 511 can effectively connect the first side top bar 503 and the second side top bar 504, which can further improve the structural strength of the ceiling frame 500.

[0107] Among them, Fig.11 As shown, there may be two first longitudinal push rods 512, and the left-right spacing between the two first longitudinal push rods 512 decreases in sequence from the front to the rear. The provision of the two first longitudinal push rods 512 can improve the structural strength of the connection body 505, and by reasonably setting the spacing between the two first longitudinal push rods 512, the connection body 505 can be adapted to the overall lines of the all-terrain vehicle, and the connection reliability between the first transverse push rod 510 and the second transverse push rod 511 can be further improved.

[0108] Also, if Fig.11 As shown, a fifth mounting bracket 513 is respectively arranged between the two first longitudinal top bars 512 and on the first transverse top bar 510. The fifth mounting bracket 513 can be used to connect some arrangement components on the ceiling frame 500. The arrangement of the fifth mounting bracket 513 can make the ceiling frame 500 have the function of integrating installation components.

[0109] like Figure 2 As shown, the first side top rod 503 and the second side top rod 504 may include a split front rod 514 and a rear rod 515, and the front rod 514 and the rear rod 515 are detachably connected. In other words, the first side top rod 503 and the second side top rod 504 may also adopt a split structure, which may be composed of two sections of rods, the front rod 514 and the rear rod 515, so that the manufacturing difficulty of the side top rods can be further reduced, and the transportation cost of the ceiling frame 500 can be further reduced. Among them, a connector similar to the first connector 506 may also be provided between the front rod 514 and the rear rod 515, which will not be described in detail here.

[0110] According to an optional embodiment of the present invention, Fig.12 and Fig.13 As shown, the third sub-frame 600 can be detachably connected to the upper part of the fuel tank compartment 150. The detachable connection method can facilitate the installation, disassembly and maintenance of the fuel tank 7000.

[0111] The rear part of the cockpit 120 is provided with a first seat mounting part for mounting a driver's seat and a second seat mounting part for mounting a passenger seat, and the fuel tank compartment 150 is located directly in front of the second seat mounting part, that is, the fuel tank compartment 150 is located directly in front of the passenger seat. Fig.12 As shown, the driver's seat can be installed on the left side of the chassis 140 in the cockpit 120, and the passenger seat can be installed on the right side of the chassis 140 in the cockpit 120. The fuel tank compartment 150 is located directly in front of the passenger seat. The area directly in front of the driver's seat can be used to install devices such as a steering wheel and display instruments. Some instruments can also be set above the fuel tank compartment 150, which can serve to cover the fuel tank compartment 150. The fuel tank port of the fuel tank 7000 can extend out of the cockpit 120 to facilitate refueling.

[0112] Specifically, Fig.13 As shown, the main frame 100 may further include: a first middle vertical bar 118, an instrument mounting frame 121 and a bottom support frame 122. The instrument mounting frame 121 is arranged in front of the first seat mounting member, and the bottom support frame 122 is arranged between the instrument mounting frame 121 and the first middle vertical bar 118 on the corresponding side. The bottom support frame 122 constitutes the bottom of the fuel tank compartment 150.
