Description

Technical Field

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

[0002] An all-terrain vehicle (ATV) is a vehicle designed for off-road use. For example, ATVs can travel in deserts and jungles. Because the off-road conditions are often harsh, handrails are necessary to protect the safety of the occupants. Known four-wheeled vehicles (such as ATVs) have handrails in the driver's and passenger compartments. Some handrails are fixedly installed inside the driver's compartment; however, these handrails are often placed along the path for passengers to get in and out of the vehicle, reducing the space available for passengers and hindering their movement. Utility Model Content

[0003] This application provides an all-terrain vehicle to address the problem of known driver's cab handrails affecting passenger access.

[0004] This application provides an all-terrain vehicle, including a frame, a running gear, a body panel, and a protective assembly. The running gear is at least partially located below the frame. The body panel is at least partially disposed on the frame, and the body panel and the frame surround to form a passenger compartment. The protective assembly extends at least partially into the passenger compartment. The protective assembly includes a handlebar tube, a mounting base, a pivot structure, and an elastic element; the mounting base is fixedly disposed on the frame. The handlebar tube has a handlebar tube connector, and the mounting base has a mounting base connector, the handlebar tube connector being rotatably connected to the mounting base connector via the pivot structure. The handlebar tube connector is slidably fitted to the mounting base connector along a pulling direction, the pulling direction being perpendicular to or obliquely intersecting the axial direction of the pivot structure. The handlebar tube has a locked position and an unlocked position, and the handlebar tube can be pulled and slid from the locked position to the unlocked position along the pulling direction. The elastic element elastically abuts against the handlebar tube connector and the mounting base connector, and can elastically press the handlebar tube against the locked position. In the locked position, the handrail tube connector and the mounting base connector are locked together to prevent relative rotation between them. In the unlocked position, the handrail tube connector and the mounting base connector are unlocked to prevent relative rotation between them.

[0005] In one possible implementation, the mounting base connector has a insertion groove extending in the pulling direction, and the handrail tube connector has a insertion tongue that slidably engages with the insertion groove in the pulling direction. The mounting base connector has a recessed limiting groove in the pulling direction, and the handrail tube connector has a protruding limiting protrusion in the pulling direction; and / or, the mounting base connector has a protruding limiting protrusion in the pulling direction, and the handrail tube connector has a recessed limiting groove in the pulling direction. In the locked position, the limiting protrusion engages with the limiting groove to limit relative rotation between the handrail tube connector and the mounting base connector. In the unlocked position, the limiting protrusion disengages from the limiting groove to unlock relative rotation between the handrail tube connector and the mounting base connector.

[0006] In one possible implementation, the insertion slot is located at the midpoint of the mounting base connector along the axial direction of the rotating shaft structure. The mounting base connector includes clamping plates located on both sides of the insertion slot, and each clamping plate has a strip-shaped groove extending in the pulling direction. The handrail tube connector is clamped between the two clamping plates. The rotating shaft structure is connected to the handrail tube connector and movably engages with the strip-shaped groove.

[0007] In one possible implementation, the clamping plate has a limiting protrusion protruding at one end facing the handrail tube, and the handrail tube has a limiting groove corresponding to the limiting protrusion along the pulling direction.

[0008] In one possible implementation, the end of the handrail tube connector facing the mounting base has a limiting protrusion, and the bottom surface of the insertion groove has a limiting groove corresponding to the limiting protrusion along the pulling direction.

[0009] In one possible implementation, the elastic element is disposed in the strip groove and elastically abuts against one side of the groove surface of the rotating shaft structure and the strip groove.

[0010] In one possible implementation, the handrail tube connector has a through hole. The pivot structure includes a bolt and a nut, with the bolt passing through a slot in one side of the clamping plate and the through hole, then exiting through a slot in the other side of the clamping plate and threaded onto the nut.

[0011] In one possible implementation, the shaft structure further includes a spacer. The spacer passes through the through hole and the two slots, and is fitted over the bolt.

[0012] In one possible implementation, there are two mounting bases, spaced apart along the height of the all-terrain vehicle. The handlebar tube is U-shaped, and its two ends are rotatably connected to the two mounting bases.

[0013] In one possible implementation, the rotation axes of the handle tube relative to the two mounting bases coincide with each other and are parallel to the height direction of the all-terrain vehicle. The pulling direction is parallel to the front-rear direction of the all-terrain vehicle.

[0014] In summary, the all-terrain vehicle of this application includes a protective assembly comprising a handle tube, a mounting base, a pivot structure, and an elastic element. The handle tube has a locked position and an unlocked position, and can be slid from the locked position to the unlocked position under tension. The elastic element elastically abuts against the handle tube connector and the mounting base connector, and can elastically press the handle tube against the locked position. In the locked position, the handle tube connector and the mounting base connector are locked together to limit relative rotation between them. In the unlocked position, the handle tube connector and the mounting base connector are unlocked to prevent relative rotation between them. The protective assembly can be easily locked in a closed state or rotated to an open state. In the closed state, the protective assembly reliably protects the occupant's safety; in the open state, the protective assembly does not obstruct the occupant's entry and exit from the vehicle.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] It should be noted that when a component is described as "connected" to another component, it can be directly connected to the other component or may have an intervening component present. When a component is considered to be "set on" another component, it can be directly set on the other component or may have an intervening component present. The terms "vertical," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] See Figure 1 This embodiment provides an all-terrain vehicle 100, which includes a frame 11, a running gear 12, a body panel 13, and a protective assembly 15. The all-terrain vehicle 100 has a longitudinal direction (X), a vertical direction (Z), and a width direction (Y).

[0026] The running gear 12 is at least partially located below the frame 11. A body panel 13 is at least partially mounted on the frame 11, and the body panel 13 and the frame 11 together form the passenger compartment 14. A protective assembly 15 extends at least partially into the passenger compartment 14 to protect occupants during driving. Occupants can use the protective assembly 15 to get in and out of the vehicle. One or more protective assemblies 15 may be provided, and the protective assembly 15 may be located on the left and / or right side of the vehicle.

[0027] The protective component 15 provided in this embodiment can be connected to the frame 11 at the rear of the passenger compartment 14 and has a closed state and an open state. In the closed state, the protective component 15 extends forward into the passenger compartment 14. At this time, the protective component 15 can protect the occupant sitting in the passenger compartment 14 and reduce the possibility of the occupant falling out of the passenger compartment 14. In the closed state, the distance d1 between the front end of the protective component 15 and the steering wheel of the all-terrain vehicle 100 is relatively small, which may affect the occupant's entry and exit from the passenger compartment 14. In view of this, the protective component 15 in this embodiment can switch between the closed state and the open state.

[0028] During the transition from the closed state to the open state, the protective component 15 rotates relative to the frame 11 about an axis parallel to the height direction Z of the all-terrain vehicle 100 to open to the outside of the passenger compartment 14, thereby increasing the size of the entrance and exit for occupants to enter and exit the passenger compartment 14, facilitating occupants' access to and from the passenger compartment 14. This will be described exemplarily below.

[0029] See Figures 2-4 The protective component 15 provided in this embodiment includes a handrail tube 151, a mounting base 152, a pivot structure 153, and an elastic element 154.

[0030] There are two mounting bases 152, which are spaced apart along the height direction Z of the all-terrain vehicle 100 and fixedly connected to the frame 11. The handle tube 151 is U-shaped. Both ends of the handle tube 151 are rotatably connected to the two mounting bases 152, and the rotation axes L1 and L2 are coincident and parallel to the height direction Z of the all-terrain vehicle 100. In this way, the handle tube 151 can rotate relative to the mounting bases 152 to open or close the protective component 15.

[0031] See also Figure 3 and Figure 4 In this embodiment, the handrail tube 151 has a handrail tube connector 1511, and the mounting base 152 has a mounting base connector 1521. The handrail tube connector 1511 is rotatably connected to the mounting base connector 1521 via a rotating shaft structure 153. The handrail tube connector 1511 is along the pulling direction F (also seen in...) Figure 1 The shaft can be slidably fitted to the mounting bracket connector 1521, and the pulling direction F is perpendicular to or obliquely intersecting the axial direction Z1 of the rotating shaft structure 153. For example, in this embodiment, the pulling direction F is parallel to or substantially parallel to the front-rear direction X of the all-terrain vehicle 100.

[0032] The handrail tube 151 has a locked position and an unlocked position. The handrail tube 151 can be pulled and slid from the locked position to the unlocked position along the pulling direction F. The elastic member 154 elastically abuts between the handrail tube connector 1511 and the mounting base connector 1521, and can elastically press the handrail tube 151 against the locked position.

[0033] In the locked position, the handrail tube connector 1511 and the mounting base connector 1521 are interlocked to prevent relative rotation between the handrail tube connector 1511 and the mounting base connector 1521, thus ensuring that the protective assembly 15 can be reliably held in the closed position (see...). Figure 1 or Figure 3 ,or Figure 5 The solid line portion serves to protect the occupants.

[0034] In the unlocked position, the handrail tube connector 1511 and the mounting base connector 1521 are unlocked from each other, allowing the handrail tube connector 1511 to rotate relative to the mounting base connector 1521. At this time, the occupant can rotate the handrail tube 151 to move the protective assembly 15 to the open position (see...). Figure 5 (The dotted line portion).

[0035] In this embodiment, optionally, the mounting base connector 1521 has a insertion groove 1524 extending along the pulling direction F, and the armrest tube connector 1511 has a insertion tongue 1512, which is slidably fitted into the insertion groove 1524 along the pulling direction F. For example, the insertion groove 1524 is located at the middle position of the mounting base connector 1521 along the axial direction of the rotating shaft structure 153 (parallel to the height direction Z of the all-terrain vehicle 100). Thus, the mounting base connector 1521 includes two clamping portions 1525 located on both sides of the insertion groove 1524, and each of the two clamping portions 1525 has a strip groove 1526 extending along the pulling direction F. The armrest tube connector 1511 is clamped between the two clamping portions 1525, and the rotating shaft structure 153 is connected to the armrest tube connector 1511 and movably fitted into the strip groove 1526.

[0036] In other embodiments, the positions of the insertion slot 1524 and the insertion tongue 1512 can be interchanged, that is, the insertion slot 1524 is located at the handrail tube connector 1511, and the insertion tongue 1512 is located at the mounting base connector 1521.

[0037] The armrest tube connector 1511 has a through hole 1513. The pivot structure 153 includes a bolt 1531 and a nut 1532. The bolt 1531 passes through the slot 1526 of the clamping plate portion 1525 on one side and the through hole 1513, and then exits from the slot 1526 of the clamping plate portion 1525 on the other side, and is threadedly connected to the nut 1532. The pivot structure 153 can slide along the extension direction of the slot 1526 (parallel to the vehicle's longitudinal direction X). Thus, when the armrest tube 151 is pulled in the pulling direction F, the armrest tube 151 can drive the pivot structure 153 to move a certain distance relative to the mounting base 152 in the pulling direction F, so as to switch from the locked position to the unlocked position. In the unlocked position, the occupant can rotate to open the armrest tube 151.

[0038] In other embodiments, the positions of the through hole 1513 and the strip groove 1526 can be interchanged. That is, the through hole 1513 is located on the clamping plate portion 1525 of the mounting base connector 1521, and the strip groove 1526 is located on the insertion tongue 1512 of the handrail tube connector 1511. It is only necessary to ensure that the mounting base connector 1521 and the handrail tube connector 1511 can slide relative to each other in the pulling direction F.

[0039] Optionally, the rotating shaft structure 153 also includes a spacer 1533. The spacer 1533 passes through the through hole 1513 and the two strip grooves 1526, and is fitted over the bolt 1531. The Z-side surfaces of the spacer 1533 in the height direction are 0.1-0.3mm higher than the mounting planes of the two clamping plates 1525 used to mate with the bolt 1531 and nut 1532. This prevents the bolt 1531 and nut 1532 from pressing against the clamping plates 1525, thus avoiding affecting the mutual rotation between the mounting base connector 1521 and the handrail tube connector 1511.

[0040] In this embodiment, the elastic element 154 is disposed in the strip groove 1526 and elastically abuts against the side of the rotating shaft structure 153 and the strip groove 1526 near the handrail tube connector 1511, so as to apply an elastic force near the mounting base connector 1521 to the handrail tube connector 1511, elastically limiting the handrail tube connector 1511 to a position that is mutually locked with the mounting base connector 1521, thereby achieving self-locking.

[0041] Optionally, in this embodiment, there are two elastic elements 154, which are respectively disposed in the strip grooves 1526 of the two clamping plates 1525.

[0042] In this embodiment, the elastic element 154 is a compression spring. In other embodiments, the elastic element 154 may also be a tension spring or other elastic structure, as long as it can elastically limit the handrail tube connector 1511 to a position that is mutually locked with the mounting base connector 1521.

[0043] The following is an exemplary description of the mutual limiting structure between the mounting base connector 1521 and the handrail tube connector 1511 in this embodiment.

[0044] See Figure 3 and Figure 4 In this embodiment, the mounting base connector 1521 has a limiting groove 161 (defined as the first limiting groove 1522) recessed along the pulling direction F, and the handrail tube connector 1511 has a limiting protrusion 162 (defined as the first limiting protrusion 1514) protruding along the pulling direction F. For example, in this embodiment, the end of the handrail tube connector 1511 facing the mounting base 152 has the first limiting protrusion 1514 protruding, and the bottom surface of the insertion groove 1524 has the first limiting groove 1522 corresponding to the first limiting protrusion 1514 along the pulling direction F.

[0045] In the locked position, the first limiting protrusion 1514 engages with the first limiting groove 1522 to limit relative rotation between the handrail tube connector 1511 and the mounting base connector 1521. At this time, the protective assembly 15 is reliably held in the closed state to protect the occupants.

[0046] In the unlocked position, the first limiting protrusion 1514 disengages from the first limiting groove 1522, thereby unlocking the relative rotation between the armrest tube connector 1511 and the mounting base connector 1521. At this time, the protective assembly 15 can be rotated to the open state to facilitate occupants entering and exiting the driver's cabin 14.

[0047] The first limiting protrusion 1514 and the first limiting groove 1522 are also visible. Figure 6 .

[0048] See also Figure 3 and Figure 4 In this embodiment, the mounting base connector 1521 is further provided with a limiting protrusion 162 (defined as the second limiting protrusion 1523) protruding along the pulling direction F, and the handrail tube connector 1511 is provided with a limiting groove 161 (defined as the second limiting groove 1515) recessed along the pulling direction F. For example, the clamping plate portion 1525 has a second limiting protrusion 1523 protruding at one end facing the handrail tube 151, and the handrail tube 151 has a second limiting groove 1515 corresponding to the second limiting protrusion 1523 along the pulling direction F.

[0049] In the locked position, the second limiting protrusion 1523 engages with the second limiting groove 1515 to limit relative rotation between the handrail tube connector 1511 and the mounting base connector 1521. At this time, the protective assembly 15 is reliably held in the closed state to protect the occupants.

[0050] In the unlocked position, the second limiting protrusion 1523 disengages from the second limiting groove 1515, thereby unlocking the relative rotation between the armrest tube connector 1511 and the mounting base connector 1521. At this time, the protective assembly 15 can be rotated to the open state to facilitate occupants entering and exiting the driver's cabin 14.

[0051] The second limiting protrusion 1523 and the second limiting groove 1515 are also visible. Figure 6 .

[0052] In addition to the all-terrain vehicle 100 mentioned above, the protective component 15 of this embodiment can also be used in other types of vehicles or means of transportation, and is not limited here.

[0053] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
