Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles capable of traveling on all terrains, featuring a high chassis, suspension with superior shock absorption, tires with good traction, and powerful engines. Compared to ordinary vehicles, ATVs can operate in extremely harsh environments, including but not limited to beaches, mountains, forests, and swamps, and are widely used in farms and recreational facilities.

[0003] In all-terrain vehicles (ATVs), the frame can be either a single piece or a rigidly connected design. Engine vibrations are transmitted to the frame through engine mounts. While engine mounts reduce the impact of engine vibrations on the frame, vibrations still penetrate the ATV's cabin, resulting in significant overall vibration and noise, leading to a poor driving and riding experience. Therefore, minimizing the negative impact of engine vibration on the ATV's riding experience is a pressing issue that needs to be addressed. Utility Model Content

[0072] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments. It should be noted that components depicted in the drawings are not necessarily shown to scale; and identical or similar components will be designated with the same or similar reference numerals or similar technical terms.

[0073] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0074] like Figure 1 As shown, this application embodiment also provides an all-terrain vehicle 100, which includes a frame 10, a body panel 20, a running system 30, and a power system 40. The body panel 20 at least partially covers the frame 10; the running system 30 is at least partially connected to the frame 10; the power system 40 is supported by the frame 10 and is used to drive the running system 30.

[0075] For ease of understanding, this application defines the directions of front, rear, left, right, up, and down. The front-rear direction refers to the length of the frame 10 of the all-terrain vehicle 100, the left-right direction refers to the width of the frame 10, and the up-down direction refers to the height of the frame 10. In this embodiment, the directions of front, rear, left, right, up, and down are based on the state of the all-terrain vehicle 100 traveling on a level surface, not on a sloping surface.

[0076] Further integration Figure 2 and Figure 3 As shown, the frame 10 includes a main support 11, a powertrain support 12, and a flexible connection structure 13. The powertrain support 12 is detachably connected to the main support 11 via the flexible connection structure 13. The main support 11 serves as the main frame, which can be used to form the driver's cabin, support seats, and connect suspensions. The powertrain support 12, as a subframe, can be used to assemble and / or support the powertrain 40, especially the engine of the powertrain 40. The powertrain 40 can be connected to the powertrain support 12 for shock absorption via a suspension structure (not shown) with a damping function. The flexible connection structure 13 is a connection structure with a damping and vibration filtering function, located at the connection between the main support 11 and the powertrain support 12, capable of filtering or even isolating vibrations transmitted from the powertrain support 12 to the main support 11.

[0077] Furthermore, by separating the powertrain bracket 12 that houses the powertrain 40 and connecting it to the main frame 11 via a flexible connection structure 13, vibration of the chassis 10 can be reduced a second time, improving the driving experience for passengers. Moreover, the engine is detachably connected to the main frame 11 via the powertrain bracket 12, providing good shock absorption and facilitating inspection, maintenance, and / or replacement of the engine, as well as inspection and maintenance of other components.

[0078] It is understandable that the engine can also be described as an engine assembly; the soft connection structure 13 may contain soft materials, but it is not limited to the soft connection structure 13 necessarily being partially or entirely made of soft materials. Those skilled in the art will understand that this is certainly feasible, and will not be elaborated here.

[0079] It is understood that the power system bracket 12 and the flexible connection structure 13 each have different functions. For ease of understanding, they are divided into different components without limiting the specific connection relationship between the power system bracket 12 and the flexible connection structure 13. The flexible connection structure 13 and the power system bracket 12 can be integrally set; or, the flexible connection structure 13 can be connected to the power system bracket 12, which is also an independent component, as an independent component. The connection methods between the two include, but are not limited to, welding and riveting.

[0080] In one embodiment, the flexible connection structure 13 includes a plurality of bushings 130, and the upper and lower sides of the bushings 130 are provided with buffers 134 that can directly contact the main support 11.

[0081] Furthermore, the all-terrain vehicle 100 provided in this embodiment includes a frame 10 comprising a main support 11 and a power system support 12. The power system support 12 supports the power system 40 and is connected to it for shock absorption, thereby achieving primary shock absorption. The power system support 12 is connected to the main support 11 via a flexible connection structure 13. Through the flexible connection of the bushing 130, engine vibration transmitted from the power system support 12 to the main support 11 can be filtered, thereby achieving secondary shock absorption and further reducing vehicle vibration and noise. Both the upper and lower sides of the bushing 130 are provided with buffer members 134 that can directly contact the main support 11. The buffer members 134 further serve as a buffer between the main support 11 and the power system support 12, avoiding hard contact between them, further reducing vehicle vibration and noise, and effectively improving the driving experience of the all-terrain vehicle 100.

[0082] In one embodiment, the rear of the main support 11 is generally semi-enclosed, and the power system support 12 is also generally semi-enclosed. The main support 11 and the power system support 12 are matched with each other and enclosed to form a receiving space 110, which is used to receive the engine of the power system 40.

[0083] In one embodiment, the power system bracket 12 is located below and rear of the main support 11. Several bushings 130 are embedded in the plate crossbeam 111, and the remaining bushings 130 are located below the upper cross tube 112, allowing the power system bracket 12 to be flexibly connected to the main support 11 via the flexible connection structure 13. The buffer 134 is configured to detachably contact the plate crossbeam 111 or the upper cross tube 112. The buffer 134 can further reduce or even eliminate the impact between the power system bracket 12 and the main support 11, thereby reducing noise and improving the driving experience of the all-terrain vehicle 100.

[0084] In this embodiment, the power system bracket 12 is located at the rear of the all-terrain vehicle 100, so that the engine is located at the rear of the all-terrain vehicle 100. Specifically, the engine in the assembled state can be located above the rear wheel axle (not shown) of the walking system 30, or behind the seat back (not shown).

[0085] Further integration Figure 3 , Figure 5 and Figure 7 As shown, in one embodiment, the main support 11 includes a plate crossbeam 111, an upper horizontal tube 112, a first left connecting beam 113, a second left connecting beam 114, a first right connecting beam 115, a second right connecting beam 116, and a connecting crossbeam 117. The plate crossbeam 111 is located at the bottom of the main support 11, and the upper horizontal tube 112 is located at the upper rear of the main support 11. The plate crossbeam 111 and the upper horizontal tube 112 are offset in the front-rear direction, and both the plate crossbeam 111 and the upper horizontal tube 112 extend approximately in the left-right direction. The first left connecting beam 113 is connected to the left end of the plate crossbeam 111 and extends upward, while the second left connecting beam 114 is connected to the other end of the first left connecting beam 113 in the vertical direction and extends rearward. The first right connecting beam 115 is connected to the right end of the plate crossbeam 111 and extends upward. The second right connecting beam 116 is connected to the other end of the first right connecting beam 115 in the vertical direction and extends backward. The connecting beam 117 is located approximately between the plate crossbeam 111 and the upper horizontal tube 112 in the front-back direction. The connecting beam 117 is approximately on the same horizontal plane as the upper horizontal beam in the vertical direction. The left end of the connecting beam 117 connects to the connection point of the first left connecting beam 113 and the second left connecting beam 114, and the right end of the connecting beam 117 connects to the connection point of the first right connecting beam 115 and the second right connecting beam 116. The first left connecting beam 113, the second left connecting beam 114, the first right connecting beam 115, the second right connecting beam 116, and the connecting beam 117 can be used to cooperate with the plate crossbeam 111 and the upper horizontal tube 112 to form a frame structure with good support strength, so that the main support 11 has a better support effect.

[0086] In other embodiments, the main support 11 may also include other connecting rods and crossbeams, which can cooperate with each other to form a frame of a predetermined shape. Those skilled in the art can make adjustments according to actual needs, which will not be elaborated here.

[0087] Further integration Figure 4 , Figure 5 and Figure 7 As shown, the power system support 12 includes a front horizontal tube 121, a left bottom tube 122, a right bottom tube 123, a lower reinforcing beam 124, a left upper tube 125, a right upper tube 126, an upper reinforcing beam 127, and a suspension connection structure 128. The front horizontal tube 121, left bottom tube 122, right bottom tube 123, and lower reinforcing beam 124 are approximately on the same horizontal plane along the vertical direction. Two bushings 130 are respectively located at the left and right ends of the front horizontal tube 121. One bushing 130 is also connected to the left bottom tube 122, and the other bushing 130 is also connected to the right bottom tube 123. The left and right ends of the lower reinforcing beam 124 are respectively connected to the middle sections of the left bottom tube 122 and the right bottom tube 123, serving as a structure for lifting the left bottom tube 122 and the right bottom tube 123. Strength; the upper left tube 125 is connected to the lower left tube 122 and extends backward and upward, with a bushing 130 connected to the end of the upper left tube 125 away from the lower left tube 122; the upper right tube 126 is connected to the lower right tube 123 and extends backward and upward, with a bushing 130 connected to the end of the upper right tube 126 away from the lower right tube 123; the left and right ends of the upper reinforcing beam 127 are respectively connected to the middle sections of the upper left tube 125 and the upper right tube 126, which are used to improve the structural strength of the upper left tube 125 and the upper right tube 126.

[0088] In one embodiment, the power system bracket 12 includes a plurality of suspension connection structures 128 for connecting the power system 40 (specifically, an engine) to the power system bracket 12 via the plurality of suspension structures to achieve primary damping. The power system bracket 12 and the main bracket 11 are connected by a flexible connection structure 13 to further achieve secondary damping.

[0089] Further integration Figure 4As shown, in this embodiment, the suspension connection structure 128 includes a first suspension connection component 1281, a second suspension connection component 1282, and a third suspension connection component 1283. The first suspension connection component 1281 connects both the upper left tube 125 and the upper right tube 126, and its connection port can be located between the upper left tube 125 and the upper right tube 126. The second suspension connection component 1282 and the third suspension connection component 1283 are respectively connected to the front horizontal tube 121 and located between the left and right ends of the front horizontal tube 121. The second suspension connection component 1282 is closer to the left end of the front horizontal tube 121, and the third suspension connection component 1283 is closer to the right end of the front horizontal tube 121. Both the second suspension connection component 1282 and the third suspension connection component 1283 protrude upwards relative to the front horizontal tube 121, with the protrusion height of the second suspension connection component 1282 being greater than that of the third suspension connection component 1283.

[0090] Understandably, the suspension structure could be, for example, a shock-absorbing component for an engine mount, containing an elastic material capable of absorbing vibrations to achieve shock absorption. Those skilled in the art will understand that this is certainly feasible, and its specific structure will not be described in detail here.

[0091] Further integration Figure 6 and Figure 8 As shown, in one embodiment, the bushing 130 includes an inner support 133, an outer sleeve 131, a cushioning filler 132, and two cushioning members 134. The inner support 133 is located in the middle of the bushing 130 and is used to fix it to the main support 11 via a connector 135. The outer sleeve 131 is sleeved on the outside of the inner support 133 and is connected to the power system support 12. The cushioning filler 132 fills the space between the outer sleeve 131 and the inner support 133. The outer sleeve 131 and the cushioning filler 132 are sandwiched between the two cushioning members 134 in the vertical direction.

[0092] In one embodiment, the inner support member 133 is configured to be connected to the main support 11 by a connector 135 passing through it in the vertical direction. Two buffer members 134 are respectively sleeved on the upper and lower ends of the inner support member 133 and extend outward in the radial direction of the inner support member 133; the length of the inner support member 133 in the vertical direction is greater than the length of the outer sleeve 131 in the vertical direction, and the outer sleeve 131 is located on the inner periphery of the buffer member 134 in the radial direction of the inner support member 133.

[0093] Understandably, the outer sleeve 131 can be connected to the powertrain bracket 12 or is itself part of the powertrain bracket 12, allowing the outer sleeve 131 to move synchronously with the powertrain bracket 12. The outer sleeve 131 is typically made of a rigid material; if the outer sleeve 131 could directly contact the main bracket 11, abnormal noise might occur due to the hard contact. Positioning the two buffer pieces 134 on the upper and lower sides of the outer sleeve 131 respectively avoids direct contact between the outer sleeve 131 and the main bracket 11, and the buffer pieces 134 absorb impacts and vibrations, further reducing vibration and improving the driving experience. The outer sleeve 131 is located radially along the inner support 133 on the inner periphery of the buffer piece 134, further preventing the outer sleeve 131 from detaching.

[0094] In this embodiment, the two buffers 134 are an upper buffer rubber block 1341 and a lower buffer rubber block 1342, which can be made of the same or different materials, such as hard rubber blocks; the buffer filler 132 can be made of rubber or other materials, which can absorb vibration and reduce impact.

[0095] It is understandable that by adjusting the materials of the upper buffer rubber block 1341, the lower buffer rubber block 1342, and the buffer filler 132 respectively, the stiffness of the bushing 130 can be adjusted adaptively, and the shock absorption effect of the flexible connection structure 13 can be flexibly adjusted. Those skilled in the art should understand that this is certainly achievable, and will not be elaborated here.

[0096] In this embodiment, the inner support member 133 includes an upper end portion 1331, a lower end portion 1332, and a middle section 1333. The upper end portion 1331 and the lower end portion 1332 are located on both sides of the middle section 1333 in the vertical direction. Two buffer members 134 are respectively sleeved on the upper end portion 1331 and the lower end portion 1332. The outer diameter of the middle section 1333 is larger than the outer diameter of the upper end portion 1331 and / or the lower end portion 1332. There is an inclined surface 1334 between the upper end portion 1331 and / or the lower end portion 1332 and the middle section 1333. The buffer filling material 132 covers the middle section 1333 and the inclined surface 1334.

[0097] In this embodiment, the inner support member 133 has a through hole 1330 extending through it in the vertical direction, for the connector 135 to pass through to connect to the main support 11. The upper buffer rubber block 1341 and the lower buffer rubber block 1342 are respectively sleeved on the upper end 1331 and the lower end 1332, positioning the buffer member 134 while avoiding the connector 135.

[0098] Understandably, the middle section 1333 protrudes relative to the upper end 1331 and the lower end 1332, and the middle section 1333 is connected to the upper end 1331 and the lower end 1332 through the inclined surface 1334, so that the connection between the buffer filling material 132 filled between the inner support 133 and the outer sleeve 131 and the inner support 133 is tighter, which can improve the absorption effect of the buffer filling material 132 on vertical vibration. At the same time, the inclined surface 1334 can also avoid local fatigue of the buffer material and improve the service life of the buffer filling material 132.

[0099] In one embodiment, the flexible connection structure 13 includes three or more bushings 130, which are spaced apart to effectively achieve shock absorption.

[0100] In this embodiment, the flexible connection structure 13 includes four bushings 130, which are respectively located at the four corners of the power system bracket 12. The two bushings 130 located at the lower part of the power system bracket 12 are nested and connected to the main body bracket 11, and the two bushings 130 located at the upper part of the power system bracket 12 are suspended and connected to the lower part of the main body bracket 11.

[0101] Further integration Figure 6 As shown, the plate beam 111 includes an upper wall 1111 and a lower wall 1112 spaced apart in the vertical direction. Two bushings 130 are embedded in the plate beam 111. The upper buffer rubber block 1341 of each bushing 130 is configured to abut against the upper wall 1111, and the lower buffer rubber block 1342 of each bushing 130 is configured to abut against the lower wall 1112. A nut 136 is provided on the side of the upper wall 1111 away from the lower wall 1112 in the vertical direction. The nut 136 can be provided in the first left connecting beam 113 and / or the first right connecting beam 115. The connector 135 passes through the lower wall 1112, the inner support member 133, and the upper wall 1111 from bottom to top to be fixedly connected to the nut 136. The cap body at the bottom end of the connector 135 is locked to the lower side of the lower wall 1112, thereby locking the bushing 130.
