Description

Technical Field

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

[0002] All-terrain vehicles are vehicles that can travel on muddy or potholed terrains such as beaches, grasslands, and gravel roads, and are widely used in outdoor adventures, recreation, and farm planting.

[0003] All-terrain vehicles (ATVs) typically have side covers on their body panels, which are used to cover the engine or transmission. Removing the side covers allows for inspection and maintenance of the engine or transmission. Currently, side covers are usually attached to the body panels or frame with screws. When removing the side covers during outdoor use, it's necessary to first clean the mud and sand covering the screws, and then use a screwdriver or wrench to remove them. This process is cumbersome and time-consuming. Utility Model Content

[0004] In view of this, this application provides an all-terrain vehicle whose side covers can be quickly removed.

[0005] One embodiment of this application provides an all-terrain vehicle, including a frame, a running gear, a power system, and body panels. At least a portion of the running gear is located below the frame. At least a portion of the power system is supported by the frame and is connected to the running gear to drive it. The body panels include side panels and side covers. The side panels are located on one side of the frame along the width direction of the all-terrain vehicle and at least partially cover the frame. The side panels have an operating opening. A plane perpendicular to the width direction of the all-terrain vehicle is defined as a projection plane. At least a portion of the power system's orthographic projection onto the projection plane lies within the outline of the operating opening's orthographic projection onto the projection plane. The side covers cover the operating opening. The side cover is equipped with a locking device, which has a locking part, and the side guard plate is equipped with a mating part. When the side cover covers the operating port, the locking device has a switchable locking state and unlocking state. When the locking device is in the unlocking state, the orthographic projection of the locking part on the projection plane does not overlap with the orthographic projection of the mating part on the projection plane. When the locking device switches from the unlocking state to the locking state, the locking part can move to the side of the mating part away from the side cover and abut against the mating part.

[0006] In some embodiments of this application, the locking fastener includes a rotating rod portion and an operating portion. The side cover is provided with a rotating hole, the rotating rod portion is inserted into the rotating hole and can rotate around its own axis, the locking portion and the operating portion are respectively provided on both sides of the side cover along the thickness direction of the side cover and are both connected to the rotating rod portion; the side cover is provided with an elastic element, the elastic element is provided between the operating portion and the side cover, and the two sides of the elastic element elastically abut against the side cover and the operating portion respectively.

[0007] In some embodiments of this application, the elastic element is ring-shaped and is sleeved on the rotating rod portion.

[0008] In some embodiments of this application, the side guard plate is provided with mounting holes. When the locking fastener is in the unlocked state and the locking fastener is inserted into the mounting hole, the orthographic projection of the locking part on the projection surface is located inside the outline of the orthographic projection of the mounting hole on the projection surface.

[0009] In some embodiments of this application, the fastener has an abutment portion, and the side cover has a first positioning portion and a second positioning portion. The first positioning portion and the second positioning portion are spaced apart around the fastener, and the abutment portion is located between the first positioning portion and the second positioning portion and can abut against the first positioning portion or the second positioning portion. When the side cover covers the operating port, the fastener is in an unlocked state when the fastener rotates to the point where the abutment portion abuts against the first positioning portion, and in a locked state when the fastener rotates to the point where the abutment portion abuts against the second positioning portion.

[0010] In some embodiments of this application, one of the side cover and the side guard plate is provided with a positioning pin, and the other of the side cover and the side guard plate is provided with a mounting part, the mounting part being provided with a positioning hole; a direction substantially perpendicular to the width direction of the all-terrain vehicle is defined as the insertion direction, and the positioning pin is inserted into the positioning hole along the insertion direction.

[0011] In some embodiments of this application, the positioning pin is provided with a positioning latching part, and the mounting part is provided with a positioning mating part. The positioning latching part is latched onto the positioning mating part to constrain the position of the positioning pin relative to the mounting part in the insertion direction.

[0012] In some embodiments of this application, one of the side cover and the side guard plate is provided with a locking engagement portion, and the other of the side cover and the side guard plate is provided with a locking mating portion. The locking engagement portion is engaged with the locking mating portion substantially along the width direction of the all-terrain vehicle to constrain the position of the side cover relative to the side guard plate in the width direction of the all-terrain vehicle.

[0013] In some embodiments of this application, the side cover is provided with a handle for fastening the side cover.

[0014] In some embodiments of this application, the vehicle body panel further includes a partition panel, which includes a lower mudguard, a front mudguard, and a rear mudguard. The lower mudguard is located below the operating opening and connected to the side guard plate. The front mudguard is located in front of the operating opening and connected to the side guard plate and / or the lower mudguard. The rear mudguard is located behind the operating opening and connected to the side guard plate and / or the lower mudguard. At least a portion of the front mudguard and at least a portion of the rear mudguard are located above the lower mudguard.

[0015] With the above-mentioned configuration, when the side cover of the all-terrain vehicle provided in this application needs to be removed, the locking fastener is operated to switch the fastener from the locked state to the unlocked state, so that the locking part can be disengaged from the mating part, thereby moving the side cover away from the side guard plate to quickly remove the side cover.

[0018] 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. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0019] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items; the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In addition, the term "side cover covering the operation port" as used in this article means that the side cover covers the operation port and the side cover is in a preset position. The "preset position" refers to the position of the side cover when it is stably connected to the side guard plate by the fasteners described in this article.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Reference Figure 1 One embodiment of this application provides an all-terrain vehicle 100. The all-terrain vehicle 100 includes a frame 11, a running gear 12, a power system (not shown), and a body panel 13.

[0023] For ease of description, this paper defines the length direction of the all-terrain vehicle 100 as the front-to-back direction, the width direction of the all-terrain vehicle 100 as the left-to-right direction, and the height direction of the all-terrain vehicle 100 as the up-down direction.

[0024] The walking system 12 includes a front wheel 121 and a rear wheel 122, at least a portion of the front wheel 121 and at least a portion of the rear wheel 122 are located below the frame 11 and are rotatably connected to the frame 11.

[0025] The powertrain includes an engine and a transmission, at least a portion of which is supported by and connected to the frame 11. The engine is drive-connected to the transmission, which is connected to the front wheels 121 and / or the rear wheels 122 via a transmission structure to drive the front wheels 121 or the rear wheels 122 to rotate. Alternatively, the transmission may be a continuously variable transmission (CVT).

[0026] The body panel 13 includes a side guard plate 131 and a side cover 132. The side guard plate 131 is located on one side of the frame 11 in the left-right direction and at least partially covers the frame 11. The side guard plate 131 also covers the engine and transmission to provide protection for the engine and transmission. For example, the side guard plate 131 is located on the left side of the frame 11.

[0027] Reference Figure 2 and Figure 3The side guard plate 131 is provided with an operation port 1311, which substantially extends through the left and right sides of the side guard plate 131. A plane perpendicular to the left-right direction is defined as a projection plane 101. At least a portion of the orthographic projection of the power system onto the projection plane 101 lies within the outline of the orthographic projection of the operation port 1311 onto the projection plane 101. In some embodiments, the side cover of the transmission lies within the outline of the orthographic projection of the operation port 1311 onto the projection plane 101, facilitating maintenance or repair operations on the transmission. In other embodiments, other parts of the transmission may lie within the outline of the orthographic projection of the operation port 1311 onto the projection plane 101. In other embodiments, at least a portion of the engine may lie within the outline of the orthographic projection of the operation port 1311 onto the projection plane 101, facilitating engine maintenance or repair operations.

[0028] Side cover 132 covers the operating port 1311 to protect the engine or transmission. It is understood that when side cover 132 covers the operating port 1311, side cover 132 abuts against side guard plate 131.

[0029] Reference Figure 4 In some embodiments, one of the side cover 132 and the side guard plate 131 is provided with a positioning pin 1321, and the other of the side cover 132 and the side guard plate 131 is provided with a mounting part 1312. The mounting part 1312 is provided with a positioning hole 1312a. The positioning pin 1321 is inserted into the positioning hole 1312a along the insertion direction X, which is basically perpendicular to the left and right direction.

[0030] For example, the lower side of the side cover 132 is provided with a positioning pin 1321, which extends downward and is rod-shaped. The side guard plate 131 is provided with a mounting part 1312, which is located below the operating port 1311. The mounting part 1312 is plate-shaped and is substantially perpendicular to the vertical direction. It can be understood that the insertion direction X is substantially parallel to the vertical direction. When installing the side cover 132, the positioning pin 1321 can be inserted downward into the positioning hole 1312a first, so that the lower side of the side cover 132 is connected to the side guard plate 131. Then, the upper side of the side cover 132 is moved toward the side guard plate 131 so that the upper side of the side cover 132 abuts against the side guard plate 131.

[0031] In some embodiments, the positioning pin 1321 is provided with a positioning latching portion 1321a, and the mounting portion 1312 is provided with a positioning mating portion 1313. The positioning latching portion 1321a is latched onto the positioning mating portion 1313 to constrain the position of the positioning pin 1321 relative to the mounting portion 1312 in the insertion direction X. Exemplarily, the positioning latching portion 1321a is located on the left side of the peripheral wall of the positioning pin 1321, and the positioning latching portion 1321a is groove-shaped; the mounting portion 1312 has the positioning mating portion 1313 located on the left side of the positioning hole 1312a. It is understood that the positioning mating portion 1313 and the mounting portion 1312 are integrally injection molded. Figure 4 The dashed line at the positioning socket 1312a of the mounting part 1312 is used to separate the positioning mating part 1313.

[0032] As the upper side of the side cover 132 moves to the right towards the side guard plate 131, the positioning pin 1321 moves to the left, causing the positioning mating part 1313 to be inserted into the positioning latching part 1321a, so that the positioning latching part 1321a and the positioning mating part 1313 are engaged. This improves the stability of the connection between the positioning pin 1321 and the mounting part 1312, thereby improving the stability of the connection between the lower side of the side cover 132 and the side guard plate 131.

[0033] In other embodiments, the positioning pin 1321 or the positioning hole 1312a may be provided on the front or rear side of the side cover 132, and the corresponding insertion direction X is basically parallel to the front and rear direction.

[0034] Reference Figure 3 In some embodiments, one of the side cover 132 and the side guard plate 131 is provided with a locking engagement portion 1322, and the other of the side cover 132 and the side guard plate 131 is provided with a locking mating portion (not shown). The locking engagement portion 1322 is engaged with the locking mating portion in a substantially left-right direction to constrain the position of the side cover 132 relative to the side guard plate 131 in the left-right direction.

[0035] For example, the upper side of the side cover 132 is provided with a locking engagement portion 1322, and the side guard plate 131 is provided with a locking mating portion. The locking engagement portion 1322 is an elastic buckle, and the locking mating portion is hole-shaped; when the upper side of the side cover 132 moves toward the side guard plate 131, the locking engagement portion 1322 can be inserted into the locking mating portion and engage with the side guard plate 131 to constrain the position of the side cover 132 relative to the side guard plate 131 in the left-right direction and the up-down direction.

[0036] Alternatively, the locking latch 1322 can be one of an A-type latch, a U-type latch, or a V-type latch; the locking latch 1322 can be made of metal or plastic, as long as the locking latch 1322 is elastic.

[0037] Reference Figure 3and Figure 4 In some other embodiments, the positioning pin 1321 and the positioning hole 1312a may be omitted, and the locking latch 1322 and the locking engagement part may be arranged in a series of intervals around the operation port 1311 so as to make the side cover 132 and the side guard plate 131 stably connected.

[0038] Reference Figure 3 In some embodiments, the side cover 132 is provided with a handle 1323. Exemplarily, the handle 1323 is basically provided on the outer peripheral wall of the upper side of the side cover 132 and is basically in the shape of a groove or a protrusion. When it is necessary to remove the side cover 132, the handle 1323 can be pressed with a finger to press the side cover 132, so that the upper side of the side cover 132 is away from the side guard plate 131, so that the locking engagement portion 1322 is disengaged from the locking mating portion.

[0039] Reference Figure 2 and Figure 5 The side cover 132 is provided with a locking fastener 1324, and the locking fastener 1324 is provided with a locking part 1324a; the side guard plate 131 is provided with a mating part 1314, and the locking part 1324a is used to abut against the mating part 1314 when the side cover 132 covers the operation port 1311, so as to fix the side cover 132 to the side guard plate 131. It can be understood that when the side cover 132 covers the operation port 1311, the locking fastener 1324 has a switchable locked state and an unlocked state.

[0040] Figure 5 The rectangular dashed frame at the operating port 1311 of the side guard plate 131 is used to represent the mating part 1314. In other embodiments, the dashed frame used to represent the mating part 1314 may also be circular or trapezoidal, as long as the locking part 1324a can abut against the mating part 1314 to fix the side cover 132 to the side guard plate 131.

[0041] Reference Figure 5 In some embodiments, the locking fastener 1324 is rotatably disposed on the side cover 132. When the locking fastener 1324 is in the unlocked state, it is inserted into the operating port 1311, and in the left-right direction, the locking part 1324a is substantially located on the side of the mating part 1314 away from the side cover 132. It can be understood that the rotation axis of the locking fastener 1324 is substantially parallel to the left-right direction. When the locking fastener 1324 is in the unlocked state, the orthographic projection of the locking part 1324a on the projection plane 101 and the orthographic projection of the mating part 1314 on the projection plane 101 do not overlap. At the same time, the orthographic projection of the locking part 1324a on the projection plane 101 is located inside the outline of the orthographic projection of the operating port 1311 on the projection plane 101, so that when the side cover 132 is installed, the locking part 1324a can be moved through the operating port 1311 from the side of the side guard plate 131 near the side cover 132 to the side away from the side cover 132.

[0042] Reference Figure 6 When the locking fastener 1324 is rotated to switch from the unlocked state to the locked state, the locking part 1324a driven by the locking fastener 1324 moves to the side of the mating part 1314 opposite to the side cover 132 and abuts against the mating part 1314, thereby fixing the side cover 132. It can be understood that when the locking fastener 1324 is in the locked state, the orthographic projection of the locking part 1324a on the projection plane 101 at least partially overlaps with the orthographic projection of the mating part 1314 on the projection plane 101.

[0043] In other embodiments, one end of the fastener 1324 can be fixedly connected to the side cover 132, and the fastener 1324 is elastic. When installing the side cover 132, the fastener 1324 can be bent and deformed by moving the fastener 132, so that the orthographic projection of the locking part 1324a on the projection surface 101 is located inside the outline of the orthographic projection of the operating port 1311 on the projection surface 101, so that the locking part 1324a can move to the side of the mating part 1314 away from the side cover 132. Then, the fastener 1324 is released, the deformation of the fastener 1324 is restored, and the locking part 1324a is moved, so that the orthographic projection of the locking part 1324a on the projection surface 101 and the orthographic projection of the mating part 1314 on the projection surface 101 at least partially overlap, so that the locking part 1324a abuts against the mating part 1314, thereby achieving the effect of fixing the side cover 132.

[0044] Reference Figure 7 and Figure 8 In some embodiments, the side guard plate 131 is provided with mounting holes 1315, which penetrate both sides of the side guard plate 131 along the thickness direction of the side guard plate 131.

[0045] When the side cover 132 covers the operating port 1311, the locking fastener 1324 is inserted into the mounting hole 1315, and in the through direction of the mounting hole 1315, the locking part 1324a is basically located on the side of the mating part 1314 away from the side cover 132. It can be understood that when the locking fastener 1324 is in the unlocked state, the orthographic projection of the locking part 1324a on the projection surface 101 is located inside the outline of the orthographic projection of the mounting hole 1315 on the projection surface 101, so that when the side cover 132 is installed, the locking part 1324a can be moved through the mounting hole 1315 from the side of the side guard plate 131 near the side cover 132 to the side away from the side cover 132. When the locking fastener 1324 is rotated to switch from the unlocked state to the locked state, the locking part 1324a driven by the locking fastener 1324 moves to the side of the mating part 1314 away from the side cover 132 and abuts against the mating part 1314 to achieve the effect of fixing the side cover 132.

[0046] Figure 7 and Figure 8The rectangular dashed frame at the mounting hole 1315 of the side guard plate 131 is used to characterize the mating part 1314. In other embodiments, the dashed frame used to characterize the mating part 1314 may also be circular or trapezoidal, as long as the locking part 1324a can abut against the mating part 1314 to fix the side cover 132 to the side guard plate 131.

[0047] With the above configuration, the inner peripheral wall of the mounting hole 1315 has a restraining effect on the locking fastener 1324 in a direction perpendicular to the through direction of the mounting hole 1315, which can improve the stability of the side cover 132. It can be understood that the through direction of the mounting hole 1315 is basically parallel to the left and right direction.

[0048] Reference Figure 9 and Figure 10 The locking element 1324 includes a rotating rod portion 1324b and an operating portion 1324d. The side cover 132 is provided with an elastic element 1325. The side cover 132 has a rotating hole 1326, into which the rotating rod portion 1324b is inserted. The locking portion 1324a and the operating portion 1324d are respectively located on both sides of the side cover 132 along its thickness direction and are both connected to the rotating rod portion 1324b. The elastic element 1325 is located between the operating portion 1324d and the side cover 132, and its two sides elastically abut against the side cover 132 and the operating portion 1324d, respectively. The rotating rod portion 1324b is essentially rod-shaped, and its axis is the rotation axis of the locking element 1324.

[0049] It is understood that when the locking fastener 1324 is in the locked state, the elastic member 1325 is in a compressed and deformed state, so that both sides of the elastic member 1325 elastically abut against the operating part 1324d and the side cover 132 respectively, so that the locking part 1324a abuts against the mating part 1314, thereby improving the stability of the locking part 1324a and the mating part 1314 in the abutting state. Alternatively, when the side cover 132 is detached from the side guard plate 131, that is, after the side cover 132 is removed, the elastic member 1325 can still be in a compressed and deformed state, so that the locking part 1324a and the side cover 132 facing away from the operating part 1324d remain in the abutting state, thereby keeping the position of the locking part 1324a in the position when the side cover 132 was removed, so as to facilitate the reinstallation of the side cover 132, while reducing the possibility of the rotating rod part 1324b falling off and reducing the risk of the elastic member 1325 falling off.

[0050] The elastic element 1325 is ring-shaped and is sleeved on the rotating rod portion 1324b, which can reduce the risk of the elastic element 1325 falling off. In some embodiments, the elastic element 1325 is a rubber ring. In other embodiments, the elastic element 1325 can be a spring or other elastic structure.

[0051] The operating part 1324d is annular and is sleeved on one end of the rotating rod part 1324b. Optionally, the operating part 1324d and the rotating rod part 1324b are integrally injection molded structures. In other embodiments, the operating part 1324d may be plate-shaped, and the operating part 1324d is connected to the end wall of the rotating rod part 1324b.

[0052] Alternatively, the orthographic projection of the elastic element 1325 onto the projection plane 101 is located inside the orthographic projection of the operating part 1324d onto the projection plane 101. This arrangement increases the contact area between the elastic element 1325 and the operating part 1324d and improves the uniformity of the elastic force on the operating part 1324d, reducing the risk of the rotating rod part 1324b becoming misaligned and jamming with the side guard plate 131 or the side cover 132.

[0053] In some embodiments, the locking fastener 1324 has an abutment portion 1324e, and the side cover 132 has a first positioning portion 1327 and a second positioning portion 1328, which are spaced apart around the locking fastener 1324. Exemplarily, the operating portion 1324d has an abutment portion 1324e on the side facing the side cover 132, and the first positioning portion 1327, the second positioning portion 1328, and the abutment portion 1324e are all protruding.

[0054] The abutment portion 1324e is disposed between the first positioning portion 1327 and the second positioning portion 1328. When the rotating rod portion 1324b is rotated by the operating portion 1324d, the abutment portion 1324e can abut against the first positioning portion 1327 or the second positioning portion 1328; the side cover 132 covers the operating port 1311 (see Figure 3 In the state where the side cover 132 covers the operation port 1311, when the abutment part 1324e abuts against the first positioning part 1327, the locking fastener 1324 is in the unlocked state; when the side cover 132 covers the operation port 1311, when the abutment part 1324e abuts against the second positioning part 1328, the locking fastener 1324 is in the locked state. This configuration facilitates the determination of the state of the locking fastener 1324.

[0055] Reference Figure 2 and Figure 11In some embodiments, the vehicle body panel 13 further includes a retaining panel 133, which includes a lower mudguard 1331, a front mudguard 1332, and a rear mudguard 1333. The lower mudguard 1331 is located below the operating opening 1311 and connected to the side guard plate 131. The front mudguard 1332 is located in front of the operating opening 1311 and connected to the side guard plate 131 and / or the lower mudguard 1331. The rear mudguard 1333 is located behind the operating opening 1311 and connected to the side guard plate 131 and / or the lower mudguard 1331. At least a portion of the front mudguard 1332 and at least a portion of the rear mudguard 1333 are located above the lower mudguard 1331. It is understood that the lower mudguard 1331, the front mudguard 1332, and the rear mudguard 1333 are all substantially plate-shaped.

[0056] It is understandable that the lower mudguard 1331, the front mudguard 1332 and the rear mudguard 1333 are basically arranged to surround the operating port 1311, which can protect the side cover 132 and the fastener 1324 and reduce the possibility of the side cover 132 or the fastener 1324 coming into contact with mud and sand.
