Description

Technical Field

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

[0002] The approach angle of an all-terrain vehicle (ATV) is the angle between the ground and the line drawn by the tangent to the front wheel of the fully loaded, stationary vehicle, where the most prominent point at the front of the vehicle is the center of gravity. For safety reasons, an ATV is often fitted with a front bumper, which reduces the approach angle. Due to varying user needs, the approach angle may need to be adjusted in certain situations. One technique involves detachably mounting the front bumper to the front of the frame, allowing adjustment of the approach angle by vertically changing its position. However, removing the front bumper is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0003] In view of this, this application provides an all-terrain vehicle with a more convenient approach angle adjustment.

[0004] This application provides an all-terrain vehicle, including a frame, body panels, a running gear, a power system, a transmission system, and a front bumper. The body panels at least partially cover the frame, the running gear is connected to the frame and at least partially located below the frame, the power system is supported by the frame and provides power to the running gear, and the transmission system drivesly connects the power system and the running gear. The front bumper is located at the front end of the frame and includes a bumper body, a first connector, and a second connector. Both the first and second connectors are fixedly connected to the bumper body. Along the height direction of the frame, the first connector is located below the second connector. The first connector is rotatably connected to the frame and has a rotation axis, which is substantially parallel to the width direction of the frame. The front bumper as a whole can swing around the rotation axis. The second connector has multiple fixing parts, each of which can be detachably connected to the frame.

[0005] Optionally, the frame includes a main frame and a front frame. Along the length of the frame, the front frame is fixedly connected to the front end of the main frame. The front frame includes a connecting body, an upper connecting part, and a lower connecting part. Both the upper connecting part and the lower connecting part are fixedly connected to the connecting body. Along the height of the frame, the upper connecting part is located below the lower connecting part. A first connecting member is rotatably connected to the upper connecting part. Each fixed part can be detachably connected to the lower connecting part.

[0006] Optionally, the second connector includes a branch pipe and a mounting plate. One end of the branch pipe is fixedly connected to the bar body, and the other end of the branch pipe is fixedly connected to the mounting plate. The side of the mounting plate is provided with multiple end holes, each end hole corresponding to a fixed part, and the end holes are located within the corresponding fixed parts. The central axis of each end hole is equidistant from the rotation axis. The all-terrain vehicle includes a locking assembly, which includes a locking connector that passes through or extends into the end hole and is at least partially connected to the lower connecting part, thereby restricting the rotation of the mounting plate relative to the lower connecting part.

[0007] Optionally, the lower connecting part includes a tube and a fixing block. Along the width direction of the frame, the fixing block is fixed to the side end of the tube. Along the width direction of the frame, the fixing block is provided with a locking hole. Multiple end holes on the side of the mounting plate can be coaxial with the locking hole one by one. The locking connector passes through the end hole coaxial with the locking hole and connects with the locking hole.

[0008] Optionally, the upper connecting part is provided with a rotating hole on its side, which extends through the upper connecting part along the width direction of the frame. The mounting plate is provided with an arc-shaped groove on its side, which connects each end hole. The center of the arc-shaped groove is located on the central axis of the rotating hole, and the locking connector can move within the arc-shaped groove.

[0009] Optionally, the mounting plate has two end holes on its side, namely a first end hole and a second end hole, which are located at the two ends of the arc groove along its own extension direction.

[0010] Optionally, the locking connector includes a locking part and a limiting part connected together, the locking part and the limiting part being arranged substantially along the width direction of the frame; the locking part extends into and connects to the lower connecting part, and the limiting part extends at least partially into the end hole, the outer diameter of the limiting part being larger than the groove width of the arc-shaped groove, so as to restrict the mounting plate from rotating relative to the lower connecting part about the rotation axis.

[0011] Optionally, the locking assembly also includes a limiting sleeve, which includes an insert section and an outer section. The insert section and the outer section are arranged along the width direction of the frame and connected to each other. The outer section is located at the end of the insert section away from the fixing block, and the outer diameter of the outer section is larger than the outer diameter of the insert section. The insert section passes through the end hole and is partially located inside the fixing block. The outer diameter of the insert section is larger than the width of the arc groove, and the outer diameter of the outer section is larger than the diameter of the end hole. Along the central axis of the limiting sleeve, a limiting part passes through the limiting sleeve and extends out from the insert section. The limiting part is connected to the lower connecting part.

[0012] Optionally, the locking connector also includes a blocking part, which is located at the end of the limiting part away from the locking part. The blocking part is located on the side of the mounting plate away from the fixed block to prevent the mounting plate from moving in the direction away from the fixed block. Along the central axis of the limiting sleeve, the end face of the outer section is also provided with an adjustment hole. The axial length of the adjustment hole is greater than the axial length of the extension section, the inner diameter of the adjustment hole is greater than the outer diameter of the limiting part, and greater than the maximum width of the blocking part. The locking assembly also includes a locking baffle, which is detachably disposed on the locking connector. The locking baffle is located between the limiting part and the outer section. The locking baffle abuts against the end face of the outer section away from the extension section. The locking connector passes through the locking baffle and the limiting sleeve in sequence and is connected to the fixed block.

[0013] Optionally, the locking assembly also includes an elastic element, which is sleeved on the outer peripheral surface of the limiting part. The elastic element abuts against the locking baffle and the inner wall of the adjusting hole near the extension section, and is used to push the limiting spacer toward the fixed block.

[0014] When the approach angle of an all-terrain vehicle needs to be adjusted via the front bumper, the front bumper can be swung around its rotation axis by disconnecting a certain fixing part of the second connector from the frame, thereby adjusting it to the required approach angle. Then, the fixing part of the second connector is fixed to the frame to complete the front bumper fixation. This eliminates the need to disassemble the entire front bumper, allowing for convenient adjustment of the all-terrain vehicle's approach angle. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0027] Please see Figure 1 and Figure 2 An all-terrain vehicle includes a frame 11, a body panel 14, a running gear 15, a power system (not shown), and a transmission system (not shown). The body panel 14 at least partially covers the frame 11, the running gear 15 is connected to the frame 11 and at least partially located below the frame 11, the power system is supported by the frame 11, and the transmission system drivesly connects the power system and the running gear 15, thereby providing power to the running gear 15.

[0028] The walking system 15 includes two front wheels 151 located in front of the all-terrain vehicle 100 and two rear wheels 152 located behind the all-terrain vehicle 100, and the front wheels 151 and the rear wheels 152 are respectively rotatably connected to the frame 11.

[0029] To facilitate the description of the technical solutions in this application, the front, rear, left, right, up, and down directions are also defined as shown in the figure. Among them, the front-rear direction refers to the length direction of the frame 11, the left-right direction refers to the width direction of the frame 11, and the up-down direction refers to the height direction of the frame 11.

[0030] Please see Figure 2 and Figure 3 In some embodiments, the all-terrain vehicle 100 also includes a front bumper 12, which is disposed at the front end of the frame 11 along the front-rear direction of the frame 11.

[0031] Please see Figure 3 and Figure 4The front bumper 12 includes a bumper body 121, a first connector 122, and a second connector 123.

[0032] Along the height direction of the frame 11, the first connector 122 is located below the bar body 121, and along the length direction of the frame 11, the second connector 123 is located behind the bar body 121.

[0033] Both the first connector 122 and the second connector 123 are fixedly connected to the bar body 121. Along the height direction of the frame 11, the first connector 122 is located below the second connector 123.

[0034] In some embodiments, the first connector 122, the second connector 123, and the lever body 121 are integrally formed. In other embodiments, the first connector 122, the second connector 123, and the lever body 121 are integrally formed and assembled and fixed together by welding or other means.

[0035] The first connecting member 122 is rotatably connected to the frame 11 and has a rotation axis L, which is parallel to the width direction of the frame 11. The front bumper 12 can swing around the rotation axis L to change the relative angle between the front bumper 12 and the frame 11. This relative angle can be understood as the angle between the edge or surface of the front bumper 12 closest to the frame 11 and the front side of the frame 11. The second connecting member 123 has multiple fixing parts, each of which can be detachably connected to the frame 11; the relative angle is different when different fixing parts are connected to the frame 11. It can be understood that when the front bumper 12 is mounted on the frame 11, at the same time, some fixing parts are connected to the frame 11, while others are not connected to the frame 11, and the number of fixing parts connected to the frame 11 at the same time can be one or more.

[0036] When the approach angle of the all-terrain vehicle 100 needs to be adjusted via the front bumper 12, the front bumper 12 is swung around the rotation axis L by disconnecting a certain fixing part of the second connector 123 from the frame 11, thereby adjusting it to the required approach angle. Then, the fixing part of the second connector 123 is fixedly connected to the frame 11, thus completing the fixing of the front bumper 12. The entire front bumper 12 does not need to be disassembled, making it easy to adjust the approach angle of the all-terrain vehicle 100.

[0037] The approach angle of the all-terrain vehicle 100 refers to the angle between the ground and the tangent line drawn from the most prominent point at the front of the vehicle and the front wheel when the vehicle is fully loaded and stationary. The first connecting member 122 is located below the second connecting member 123. Firstly, the first connecting member 122 is rotatably connected to the frame 11 around the rotation axis L. The position of the first connecting member 122 along the length of the frame 11 does not change. The approach angle of the all-terrain vehicle 100 is determined by the degree of forward swing of the lever 121. The adjustment process is linear and convenient. If the first connecting member 122 is positioned above the second connecting member 123, making the second connecting member 123 closer to the front wheel, the second connecting member 123 has a greater impact on the approach angle. Secondly, the fixed part of the second connecting member 123 is located above the first connecting member 122, which improves the convenience of manual adjustment and also mitigates the problem of locking at the movable point.

[0038] Please see Figure 3 and Figure 4 In some embodiments, the first connector 122 is welded and fixed to the lower part of the bar body 121. Along the width direction of the frame 11, the side of the first connector 122 is provided with a through hole 1221, which penetrates the first connector 122 along the width direction of the frame 11.

[0039] The frame 11 includes a main frame 111 and a front frame 112. Along the length of the frame 11, the front frame 112 is fixedly connected to the front end of the main frame 111.

[0040] The front frame 112 includes a connecting body 1121, an upper connecting part 1122 and a lower connecting part 1123, both of which are fixedly connected to the connecting body 1121.

[0041] In some embodiments, the connecting body 1121 is plate-shaped, the lower connecting part 1123 is cylindrical, and the upper connecting part 1122 is square.

[0042] Along the height direction of the frame 11, the upper connecting part 1122 is located below the lower connecting part 1123. The first connecting member 122 is rotatably connected to the upper connecting part 1122, and each fixing part can be detachably connected to the lower connecting part 1123.

[0043] In some embodiments, a rotating hole 1122a is provided on the side of the upper connecting portion 1122 along the width direction of the frame 11, and the rotating hole 1122a penetrates the upper connecting portion 1122 along the width direction of the frame 11. The rotating hole 1122a on the side of the upper connecting portion 1122 is coaxially arranged with the through hole 1221 on the side of the first connecting member 122, that is, the central axis of the rotating hole 1122a is collinear with the central axis of the through hole 1221.

[0044] The all-terrain vehicle 100 also includes a rotating connector 131 that passes through a through hole 1221 and a rotating hole 1122a, so that the first connector 122 is rotatably connected to the upper connecting part 1122.

[0045] In some embodiments, the rotating connector 131 is a connecting stud.

[0046] Define a plane perpendicular to the width direction of the frame 11 and passing through the center of the width of the frame 11 as the longitudinal plane S. Two second connectors 123 are provided, and the two second connectors 123 are symmetrically arranged about the longitudinal plane S.

[0047] The following description focuses on one of the second connectors, 123.

[0048] Please see Figure 4 and Figure 5 and combined Figure 3 In some embodiments, the second connector 123 includes a branch pipe 1231 and a mounting plate 1232. One end of the branch pipe 1231 is fixedly connected to the bar body 121, and the other end of the branch pipe 1231 is fixedly connected to the mounting plate 1232.

[0049] Along the width direction of the frame 11, the side of the mounting plate 1232 is provided with multiple end holes, each corresponding to a fixing part, and the end holes are located within the corresponding fixing parts. The central axis of each end hole is equidistant from the rotation axis L. That is, the centers of the multiple end holes are smoothly connected to form an arc, and the center of this arc is located on the rotation axis L.

[0050] Please see Figure 5 and Figure 6 Along the width direction of the frame 11, a locking hole 1123b1 is provided on the end face of the lower connecting part 1123. Multiple end holes on the side of the mounting plate 1232 can be coaxial with the locking hole 1123b1 one by one.

[0051] Please combine them together Figure 2 The all-terrain vehicle 100 includes a locking assembly 13, which includes a locking connector 132. The locking connector 132 passes through an end hole coaxial with the locking hole 1123b1 and is threadedly connected to the locking hole 1123b1. The locking connector 132 is fixedly connected to the second connector 123 and the lower connector 1123.

[0052] Please see Figure 5 In some embodiments, the mounting plate 1232 has two end holes on its side, namely a first end hole 1232a and a second end hole 1232b. The distance between the central axis of the first end hole 1232a and the rotation axis L is equal to the distance between the central axis of the second end hole 1232b and the rotation axis L.

[0053] In some embodiments, the diameter of the first end hole 1232a is equal to the diameter of the second end hole 1232b.

[0054] In some embodiments, along the width direction of the frame 11, the side of the mounting plate 1232 is provided with an arc-shaped groove 1232c, which connects to each end hole.

[0055] In some embodiments, the arc groove 1232c connects to the first end hole 1232a or the second end hole 1232b, and the center of the arc groove 1232c is located on the central axis of the rotating hole 1122a.

[0056] In some embodiments, the width of the arc-shaped groove 1232c is smaller than the diameter of the first end hole 1232a, and the width of the arc-shaped groove 1232c is smaller than the diameter of the second end hole 1232b.

[0057] Please see Figure 5 and Figure 6 and combined Figure 4 In some embodiments, the lower connecting portion 1123 includes a tube body 1123a and a fixing block 1123b. The tube body 1123a is a hollow structure, and the fixing block 1123b is fixed to the side end of the tube body 1123a along the width direction of the frame 11, so that the end face of the lower connecting portion 1123 along the width direction of the frame 11 can be connected to other components. A locking hole 1123b1 is provided on the end face of the fixing block 1123b along the width direction of the frame 11. Multiple end holes on the side of the mounting plate 1232 can be coaxially aligned with the locking hole 1123b1. The locking hole 1123b1 is provided on the end face of the fixing block 1123b along the width direction of the frame 11. The locking connector 132 passes through the end hole coaxial with the locking hole 1123b1 and is connected to the locking hole 1123b1.

[0058] In some embodiments, the fixing block 1123b is welded to the tube body 1123a.

[0059] In some embodiments, the fixing block 1123b is threadedly connected to the tube body 1123a.

[0060] In some embodiments, the locking connector 132 is generally cylindrical. The locking connector 132 includes a locking part 1321, a limiting part 1322, and a blocking part 1323 connected together, and the locking part 1321, the limiting part 1322, and the blocking part 1323 are arranged along the width direction of the frame 11.

[0061] The locking part 1321 extends into the lower connecting part 1123 and connects to the lower connecting part 1123. The limiting part 1322 extends at least partially into the first end hole 1232a or the second end hole 1232b. The outer diameter of the limiting part 1322 is larger than the width of the arc groove 1232c to restrict the mounting plate 1232 from rotating about the rotation axis L relative to the lower connecting part 1123. This improves the problem of relative movement between the mounting plate 1232 and the limiting part 1322 due to external forces and improves the positional stability of the front bumper 12.

[0062] In some embodiments, the limiting portion 1322 is partially located within an end hole coaxial with the locking hole 1123b1, the end hole being either a first end hole 1232a or a second end hole 1232b. The locking portion 1321 extends into the locking hole 1123b1 and is threadedly connected to it. The blocking portion 1323 is located on the side of the mounting plate 1232 away from the fixing block 1123b and presses the mounting plate 1232 against it.

[0063] When the approach angle of the all-terrain vehicle 100 needs to be adjusted via the front bumper 12, the locking connector 132 is removed, and the entire front bumper 12 is rotated around the rotation axis L so that the first end hole 1232a, which is coaxial with the locking hole 1123b1, is adjusted to the second end hole 1232b. Then, the locking connector 132 is passed through the second end hole 1232b and locked into the locking hole 1123b1. There is no need to disassemble the entire front bumper 12, which greatly enhances the convenience of manual adjustment.

[0064] In some embodiments, the locking connector 132 is a stepped bolt.

[0065] In other embodiments, the outer diameter of the limiting part 1322 is smaller than the width of the arc groove 1232c, and the blocking part 1323 is located on the side of the mounting plate 1232 away from the fixing block 1123b. When the locking part 1321 extends into the locking hole 1123b1 and is threadedly connected to the locking hole 1123b1, the blocking part 1323 presses the mounting plate 1232 against the end face of the fixing block 1123b, thereby fixing the relative position of the mounting plate 1232 and the fixing block 1123b. Since the outer diameter of the limiting part 1322 is smaller than the width of the arc groove 1232c, when it is necessary to adjust the approach angle of the all-terrain vehicle 100 through the front bumper 12, it is not necessary to remove the locking connector 132; it is only necessary to loosen the locking connector 132.

[0066] Please see Figure 5 and Figure 7 and combined Figure 4 In some embodiments, the locking component 13 ( Figure 2 It also includes a limiting sleeve 133, which is generally cylindrical in shape.

[0067] The limiting sleeve 133 includes an insert section 1331 and an outer section 1332, which are arranged along the width direction of the frame 11 and connected to each other. The outer section 1332 is located at the end of the insert section 1331 away from the fixing block 1123b, and the outer diameter of the outer section 1332 is larger than the outer diameter of the insert section 1331.

[0068] The extension section 1331 passes through the end hole and is partially located inside the fixing block 1123b. The outer diameter of the extension section 1331 is greater than the width of the arc groove 1232c, and the outer diameter of the external section 1332 is greater than the diameter of the first end hole 1232a or the second end hole 1232b.

[0069] In some embodiments, the end face of the fixing block 1123b along the width direction of the frame 11 is further provided with a receiving hole 1123b2, and the extension section 1331 passes through the end hole and is partially located in the receiving hole 1123b2. The diameter of the locking hole 1123b1 is smaller than the diameter of the receiving hole 1123b2, and the diameter of the receiving hole 1123b2 is slightly larger than the outer diameter of the extension section 1331, so that the extension section 1331 partially extends into the receiving hole 1123b2 but cannot enter the locking hole 1123b1.

[0070] In some embodiments, along the central axis of the limiting sleeve 133, a first hole 1331a is provided on the end face of the limiting sleeve 133, the first hole 1331a penetrating the extension section 1331 and the outer section 1332. The limiting part 1322 passes through the first hole 1331a, the locking part 1321 extends out from the extension section 1331 and is threadedly connected to the locking hole 1123b1, and the blocking part 1323 is located on the side of the outer section 1332 away from the fixing block 1123b, and presses the limiting sleeve 133.

[0071] The extension section 1331 passes through the first end hole 1232a or the second end hole 1232b and partially extends into the receiving hole 1123b2, thereby limiting the mounting plate 1232, improving the problem of relative movement between the mounting plate 1232 and the limiting part 1322 due to external forces, and improving the positional stability of the front bumper 12.

[0072] By setting a limiting spacer 133, the problem of damage caused by direct impact of the mounting plate 1232 on the locking connector 132 is improved, thereby increasing the service life of the locking connector 132.

[0073] When the approach angle of the all-terrain vehicle 100 needs to be adjusted via the front bumper 12, the locking connector 132 and the limiting spacer 133 are removed, and the entire front bumper 12 is controlled to rotate around the rotation axis L so that the first end hole 1232a, which is coaxial with the locking hole 1123b1, is adjusted to the second end hole 1232b. Then, the limiting spacer 133 is passed through the second end hole 1232b and partially inserted into the receiving hole 1123b2. Finally, the locking connector 132 is passed through the limiting spacer 133 and locked into the locking hole 1123b1. The entire front bumper 12 does not need to be disassembled, making manual adjustment highly convenient.

[0074] Please see Figure 5 and Figure 8 and combined Figure 4 In some embodiments, along the central axis of the limiting sleeve 133, the end face of the outer segment 1332 is also provided with an adjustment hole 1332a. The inner diameter of the adjustment hole 1332a is larger than the outer diameter of the limiting part 1322 and larger than the maximum width of the blocking part 1323, that is, the blocking part 1323 can enter the adjustment hole 1332a.

[0075] Locking component 13 ( Figure 2 It also includes a locking baffle 134, which is located between the limiting part 1322 and the outer section 1332, and the locking baffle 134 abuts against the end face of the outer section 1332 away from the extension section 1331.

[0076] The surface of the locking baffle 134 is provided with an insertion groove 1341, which penetrates the locking baffle 134 along the thickness direction and extends to the side of the locking baffle 134 along its length direction.

[0077] The width of the insertion groove 1341 is slightly larger than the outer diameter of the limiting part 1322, so that the locking baffle 134 can be engaged with the outer peripheral surface of the limiting part 1322. The width of the insertion groove 1341 is smaller than the maximum width of the blocking part 1323, so that the locking baffle 134 can block the blocking part 1323.

[0078] The locking connector 132 passes sequentially through the locking baffle 134 and the limiting spacer 133. The locking part 1321 extends out from the insertion section 1331 and is threadedly connected to the locking hole 1123b1. The blocking part 1323 is located on the side of the locking baffle 134 away from the fixing block 1123b and presses the locking baffle 134. The insertion section 1331 passes through the first end hole 1232a or the second end hole 1232b and partially extends into the receiving hole 1123b2, thereby limiting the mounting plate 1232 and fixing the relative position of the mounting plate 1232 and the fixing block 1123b.

[0079] In some embodiments, along the central axis of the limiting spacer 133, the axial length of the adjusting hole 1332a is greater than the axial length of the extension section 1331. When it is necessary to adjust the approach angle of the all-terrain vehicle 100 via the front bumper 12, the limiting spacer 133 can be pulled by loosening the locking connector 132 (without removing it) and removing the locking baffle 134, so that the blocking part 1323 enters the adjusting hole 1332a. Since the axial length of the adjusting hole 1332a is greater than the axial length of the extension section 1331, the extension section 1331 can be completely disengaged from the first end hole 1232a.

[0080] The entire front bumper 12 is controlled to rotate around the rotation axis L so that the first end hole 1232a, which is coaxial with the locking hole 1123b1, is adjusted to the second end hole 1232b. Then, the limiting sleeve 133 is passed through the second end hole 1232b and partially extended into the receiving hole 1123b2. Then, the locking connector 132 is passed through the limiting sleeve 133 and locked into the locking hole 1123b1. There is no need to remove the locking connector 132, which further improves the convenience of manual adjustment.

[0081] In some embodiments, locking component 13 ( Figure 2 It also includes an elastic element 135, which is sleeved on the outer peripheral surface of the limiting part 1322. The elastic element 135 abuts against the locking baffle 134 and the inner wall of the receiving hole 1123b2 near the extension section 1331. The elastic element 135 is used to push the limiting spacer 133 toward the fixing block 1123b.

[0082] When the approach angle of the all-terrain vehicle 100 needs to be adjusted via the front bumper 12, the locking connector 132 is loosened (without needing to be removed), the locking baffle 134 is removed, and the limiting sleeve 133 is pulled, so that the blocking part 1323 enters the adjustment hole 1332a, and the extension section 1331 completely disengages from the first end hole 1232a. By controlling the entire front bumper 12 to rotate around the rotation axis L, the first end hole 1232a, which is coaxial with the locking hole 1123b1, is adjusted to the second end hole 1232b. The force of pulling the limiting sleeve 133 is eliminated, and the elastic member 135 can automatically push the limiting sleeve 133 toward the fixing block 1123b, so that the extension section 1331 passes through the second end hole 1232b and partially extends into the receiving hole 1123b2. This eliminates the need for manually pushing the limiting sleeve 133, further improving the convenience of manual adjustment.

[0083] In some embodiments, the elastic element 135 is a compression spring.

[0084] Please see Figure 8 and Figure 9 In some embodiments, the locking component 13 ( Figure 2It also includes an insertion baffle 136, which is sleeved on the outer peripheral surface of the limiting part 1322.

[0085] The insertion baffle 136 includes a straight portion 1361 and a warped portion 1362. The warped portion 1362 is disposed on the outer peripheral surface of the straight portion 1361 and is bent toward the fixing block 1123b. The side of the straight portion 1361 facing the fixing block 1123b is used to abut against the elastic member 135, and the side of the straight portion 1361 away from the fixing block 1123b is used to abut against the blocking portion 1323 or the locking baffle 134.

[0086] When the locking baffle 134 is removed from the locking connector 132, the elastic member 135 pushes the straight portion 1361 to abut against the blocking portion 1323. There is a gap between the warped portion 1362 and the blocking portion 1323, which allows the locking baffle 134 to be inserted between the blocking portion 1323 and the straight portion 1361, thereby improving the ease of insertion of the locking baffle 134.

[0087] When the approach angle of the all-terrain vehicle 100 needs to be adjusted via the front bumper 12, the locking connector 132 is loosened (without needing to be removed), and the locking baffle 134 is removed. At this time, the elastic member 135 pushes the straight part 1361 against the blocking part 1323. The limiting sleeve 133 is pulled so that the blocking part 1323 enters the adjustment hole 1332a, and the extension section 1331 completely disengages from the first end hole 1232a. Control the entire front bumper 12 to rotate around the rotation axis L, so that the first end hole 1232a, which is coaxial with the locking hole 1123b1, is adjusted to the second end hole 1232b. The force pulling the limiting sleeve 133 is canceled, and the elastic element 135 can automatically push the limiting sleeve 133 toward the fixing block 1123b, so that the limiting sleeve 133 part extends into the receiving hole 1123b2. Then, the locking baffle 134 is inserted between the blocking part 1323 and the straight part 1361 to lock the locking connector 132, thereby fixing the relative position of the mounting plate 1232 and the fixing block 1123b.

[0088] Please see Figure 3 and Figure 4 When the extension section 1331 is located at the first end hole 1232a or the second end hole 1232b, the distance by which the position of the front bumper 12 changes along the length direction of the frame 11 is D, and the angle of change of the front bumper 12 is ΔX=∠α-∠β.

Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
