The frame 11 constitutes the basic framework of the all-terrain vehicle 100, and the frame 11 is used to support other components of the all-terrain vehicle 100. The power assembly 13 is transmission-connected to the traveling assembly 12, and the power assembly 13 is used to provide a driving force to drive the traveling assembly 12, thereby realizing the movement of the all-terrain vehicle 100. The transmission assembly 14 includes a transmission shaft 141, and the transmission shaft 141 is used to transmit the driving force generated by the power assembly 13. The power assembly 13 is transmission-connected to the traveling assembly 12 through the transmission assembly 14. The suspension assembly 15 is fixedly connected to the power assembly 13, and at least a part of the suspension assembly 15 is also fixedly connected to the frame 11. The suspension assembly 15 is used to support the power assembly 13, and the suspension assembly 15 can also reduce and control the transmission of vibration of the power assembly 13. In order to clearly illustrate the technical solution of the present application, it is also defined as follows Figure 1 As shown in the figure, the front side, rear side, left side, right side, upper side and lower side. It can be understood that the front-to-back direction in the embodiment of the present application refers to the length direction of the all-terrain vehicle 100, the left-right direction refers to the width direction of the all-terrain vehicle 100, and the up-down direction refers to the height direction of the all-terrain vehicle 100. Among them, at least part of the walking assembly 12 is located below the frame 11.

[0024] like Figure 3 and Figure 4 As shown, as an implementation, the all-terrain vehicle 100 further includes a suspension bracket 16, which is mainly used to connect the suspension assembly 15 to the frame 11 to avoid interference between the suspension assembly 15 and the transmission shaft 141 when the suspension assembly 15 is directly connected to the frame 11. The all-terrain vehicle 100 further includes a cargo box assembly 17 (see Figure 2), the cargo box assembly 17 is located at the rear of the frame 11, and the cargo box assembly 17 is mainly used to accommodate cargo for the convenience of cargo transportation, the power assembly 13 is located below the cargo box assembly 17, the suspension bracket 16 is located in front of the power assembly 13, and the transmission shaft 141 is also located in front of the power assembly 13, and the transmission shaft 141 is at least partially connected to the power assembly 13 after passing through the suspension bracket 16 along the length direction of the all-terrain vehicle 100. Specifically, the suspension bracket 16 includes a support frame 161 and a mounting frame 162, the support frame 161 is fixedly connected to the frame 11 by welding, at least part of the mounting frame 162 is located above the support frame 161, and the mounting frame 162 is also fixedly connected to the support frame 161 by welding, so that the suspension bracket 16 is fixedly connected to the frame 11, and the welding method can also improve the connection strength between the suspension bracket 16 and the frame 11, and the suspension assembly 15 is fixedly connected to the frame 11 through the mounting frame 162 and the support frame 161. Among them, the mounting frame 162 can be set as a round tube structure, and the mounting frame 162 can also be set as a square tube structure. The production cost of the round tube is lower than that of the square tube, and the square tube is easier to weld. In actual production, different types of mounting frames 162 can be selected according to different needs. Further, the mounting frame 162, the support frame 161 and the frame 11 are surrounded by an avoidance area, and at least part of the transmission shaft 141 passes through the avoidance area. When observed along the height direction of the all-terrain vehicle 100, the mounting frame 162, the frame 11 and the transmission shaft 141 at least partially overlap. Through the above-mentioned setting, the transmission shaft 141 passes through the bottom of the mounting frame 162, so that the suspension bracket 16 can avoid the transmission shaft 141 setting, thereby avoiding interference between the suspension bracket 16 and the transmission shaft 141, and avoiding collision between the suspension bracket 16 and the transmission shaft 141 during the installation of the power assembly 13, thereby improving the assembly performance of the all-terrain vehicle 100.

[0025] Furthermore, the support frame 161 includes a first support frame 1611 and a second support frame 1612 distributed along a preset direction, and the two ends of the mounting frame 162 are fixedly connected to the first support frame 1611 and the second support frame 1612 respectively, and the mounting frame 162, the first support frame 1611, the frame 11 and the second support frame 1612 surround to form an avoidance area. Through the above arrangement, when observed along the length direction, the first support frame 1611, the second support frame 1612 and the mounting frame 162 form a portal frame structure, and the avoidance area is composed of the portal frame structure. The portal frame structure has a simple structure, is easy to manufacture and install, and can withstand a large load, so that it can avoid the transmission shaft 141 while also meeting the structural strength requirements of the suspension bracket 16. Taking the present application as an example, the transmission shaft 141 of the present application is located at the left front of the power assembly 13, and the suspension assembly 15 of the present application is arranged in four. In the present application, the aforementioned preset direction refers to the width direction of the all-terrain vehicle 100, and the four suspension components 15 are arranged in pairs in front and behind the power component 13. For the suspension component 15 arranged in the left front of the power component 13, the suspension bracket 16 of the present application can avoid interference between the suspension bracket 16 and the transmission shaft 141.

[0026] It is understandable that the preset direction may also be other directions, for example, the preset direction may also be the length direction. When the preset direction is the length direction, the suspension components 15 are respectively located on both sides of the width direction of the all-terrain vehicle 100.

[0027] In this embodiment, the suspension assembly 15 includes a connecting member 153 connected to the power assembly 13, and a left support plate 151 and a right support plate 152 distributed along a preset direction. The left support plate 151 and the right support plate 152 are both connected to the mounting frame 162, and the left support plate 151 and the right support plate 152 are also connected to the connecting member 153, and at least a portion of the connecting member 153 is located between the left support plate 151 and the right support plate 152. Further, the suspension bracket 16 includes a fixing member 163, the fixing member 163 is fixedly connected to the mounting frame 162, and the left support plate 151 and / or the right support plate 152 are connected to the fixing member 163, so that there are three connection modes between the left support plate 151 and the right support plate 152 and the mounting frame 162, that is, the left support plate 151 is connected to the mounting frame 162 through the fixing member 163, and the right support plate 152 is directly connected to the mounting frame 162; or the left support plate 151 is directly connected to the mounting frame 162, and the right support plate 152 is fixedly connected to the mounting frame 162 through the fixing member 163; or when two fixing members 163 are provided, the left support plate 151 and the right support plate 152 are respectively connected to the mounting frame 162 through one fixing member 163. Among them, the fixing member 163 is detachably connected to the left support plate 151 and / or the right support plate 152 by bolts.

[0028] It should be noted that the left support plate 151 and the right support plate 152 may also be directly connected to the mounting frame 162 .

[0029] Through the above-mentioned settings, in the present application, both the left support plate 151 and the right support plate 152 can be detachably connected to the mounting frame 162 through the fixing member 163, so that the installation process of the suspension assembly 15 can be optimized, the installation of the suspension assembly 15 is convenient, and the assembly efficiency of the suspension assembly 15 is improved. The left support plate 151 and the right support plate 152 can also be directly connected to the mounting frame 162, so that the connection strength between the suspension assembly 15 and the mounting frame 162 can be improved, and then the appropriate connection method can be selected according to the actual needs. It should be noted that the present application adopts the method of connecting the left support plate 151 to the mounting frame 162 through the fixing member 163, and directly connecting the right support plate 152 to the mounting frame 162, so as to improve the assembly efficiency of the suspension assembly 15 and the mounting frame 162 while taking into account the connection strength between the suspension assembly 15 and the mounting frame 162.

[0030] Further, the mounting frame 162 is provided with a mounting hole 1621, and the fixing member 163 is provided with a through hole (not shown), the mounting hole 1621 and the through hole are connected, the inner diameters of the mounting hole 1621 and the through hole are the same, and the axes of the mounting hole 1621 and the through hole are in the same straight line, and the suspension bracket 16 also includes a fastener 164, which passes through the mounting hole 1621 and the through hole and is connected to the left support plate 151 or the right support plate 152. It can be understood that since the inner diameters of the mounting hole 1621 and the through hole are consistent and the axes of the mounting hole 1621 and the through hole are in the same straight line, the mounting hole 1621 and the through hole can be regarded as a whole long hole, which passes through the mounting frame 162 and the fixing member 163, so that the fastener 164 passes through the long hole and is connected to the left support plate 151 or the right support plate 152, and then the left support plate 151 or the right support plate 152 can be connected to the mounting frame 162 through the fixing member 163. Through the above arrangement, for the left support plate 151 or the right support plate 152, on the basis of the fixing member 163 being connected to the left support plate 151 and / or the right support plate 152 by bolts, the fastener 164 is connected to the left support plate 151 or the right support plate 152 through the mounting hole 1621, which can improve the connection strength and connection stability between the left support plate 151 or the right support plate 152 and the fixing member 163. The fastener 164 in the present application can also be configured as a bolt or a screw, etc.

[0031] In this embodiment, the all-terrain vehicle 100 also includes an electrical device (not shown), and the suspension bracket 16 is also provided with a connecting frame 165 for fixing the electrical device. At least a portion of the connecting frame 165 is arranged above the mounting frame 162 to avoid interference with the transmission shaft 141 located below the mounting frame 162. The connecting frame 165 is fixedly connected to the mounting frame 162 and the right support plate 152. It should be noted that in the present application, the electrical device mentioned above refers to an electronic three-way valve, and the electrical device can also be set as other electrical devices. Through the above-mentioned arrangement, the suspension bracket 16 can connect the electronic three-way valve to the frame 11 through the suspension bracket 16 by integrating the connecting frame 165, thereby improving the connection stability of the electronic three-way valve. In addition, the connecting frame 165 can also be used to fix the cooling water pipe of the power assembly 13, so that the pipeline layout of the cooling water pipe can be optimized.

[0032] like Figure 5 As shown, further, when viewed along a preset direction, the support frame 161 is basically a triangular structure, wherein the bottom side of the triangular structure is fixedly connected to the frame 11, and the top angle of the triangular structure is fixedly connected to the mounting frame 162. Through the above arrangement, the stability of the triangular structure is better, thereby improving the connection strength between the suspension bracket 16 and the frame 11, avoiding the breakage of the suspension bracket 16, and further improving the connection stability of the suspension assembly 15.

[0033] like Figure 6 As shown, as an implementation method, along the height direction of the all-terrain vehicle 100, the minimum distance between the mounting frame 162 and the frame 11 is defined as the height H2 of the avoidance area, and the ratio of the height H2 of the avoidance area to the diameter H1 of the transmission shaft 141 is greater than 1 and less than or equal to 6.7. Along the preset direction, the minimum distance between the first support frame 1611 and the second support frame 1612 is defined as the length H3 of the avoidance area, and the ratio of the length H3 of the avoidance area to the diameter H1 of the transmission shaft 141 is greater than 1 and less than or equal to 6.7. In the present application, the diameter H1 of the transmission shaft 141 is 45 mm, the height H2 of the avoidance area is 117 mm, and the length H3 of the avoidance area is 210 mm, so the ratio of H2 to H1 is 2.6, and the ratio of H3 to H1 is 4.7. Through the above-mentioned settings, it is possible to avoid the ratio of H2 to H1 being too large and / or the ratio of H3 to H1 being too large, thereby avoiding interference between the suspension bracket 16 and other components of the all-terrain vehicle 100 due to the excessive frame size of the suspension bracket 16; it is also possible to avoid the ratio of H2 to H1 being too small and / or the ratio of H3 to H1 being too small, thereby avoiding interference between the transmission shaft 141 and the suspension bracket 16 due to an excessively small avoidance area.

[0034] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
