An all-terrain vehicle with a crash avoidance mechanism

Abstract

This application discloses an all-terrain vehicle with an anti-collision mechanism, relating to the field of all-terrain vehicles. It includes a vehicle body and an anti-collision mechanism installed at the bottom of the body. The anti-collision mechanism includes a mounting base, a rotating box, lateral support wheels, and a diagonal bar. The rotating box contains an adjustment assembly. Through the arrangement of an electric push rod, diagonal bar, rotating box, limit seat, inner support spring, and lateral support wheel, the rotation angle of the rotating box can be adjusted, thereby adjusting the tilt angle of the lateral support wheel. This facilitates use and adaptability to different road conditions, providing stable lateral support force and preventing rollover. Rotating the rotating block with a wrench or other tools drives the worm gear, which in turn drives the worm wheel, which in turn drives the threaded rod. This causes the compression disc to move on the outer surface of the threaded rod. After the compression disc moves, the compression force on the top of the compression spring is adjusted, thereby adjusting the preload of the compression spring to adapt to different driving conditions.

Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle technology, and in particular to an all-terrain vehicle with a collision avoidance mechanism. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles designed to travel on a variety of terrains, including sand, mud, rocks, and snow. They typically have four large wheels, providing excellent off-road performance and maneuverability, making them suitable for driving on unpaved roads. ATVs are widely used in agriculture, forestry, rescue, recreation, and many other fields, improving work efficiency and enhancing the enjoyment of life.

[0003] All-terrain vehicles (ATVs) can be categorized into two types based on their operating method: straddle-mounted and ride-on. Taking the straddle-mounted type as an example, an ATV is similar to a four-wheeled motorcycle, where the operator straddles the top of the vehicle and operates it via the handlebars. Existing straddle-mounted ATVs primarily focus on collision protection at the front and rear of the vehicle, typically including a front bumper, front bumper extensions, and a rear bumper. These components effectively cushion the impact on the front and rear of the vehicle, protecting the vehicle and reducing the impact on the operator.

[0004] The existing collision protection mechanisms of straddle-type all-terrain vehicles are mainly located at the front and rear of the vehicle body. However, compared with ride-on all-terrain vehicles, the side protection mechanism of straddle-type all-terrain vehicles is relatively weak. When the vehicle body is affected by a side impact, the straddle-type all-terrain vehicle is prone to rollover accidents, which affects the safety of the driver and is inconvenient to use.

The anti-collision mechanism includes a mounting base installed at the bottom of the vehicle body. Two rotating boxes are hinged to the bottom of the mounting base. The bottom of the rotating boxes is provided with lateral support wheels. The outer surfaces of the two rotating boxes are provided with diagonal bars. The ends of the two diagonal bars away from the rotating boxes are hinged to each other. An adjustment assembly is disposed inside the rotating box. The adjustment assembly includes a threaded rod movably installed inside the rotating box. A pressing disc is engaged with the outer surface of the threaded rod.

[0012] (III) Beneficial Effects This utility model provides an all-terrain vehicle with a collision avoidance mechanism. It has the following beneficial effects: 1.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1 Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present invention, which provides an all-terrain vehicle with a collision avoidance mechanism 2, and a vehicle body 1; The anti-collision mechanism 2 is located at the bottom of the vehicle body 1. The anti-collision mechanism 2 includes a mounting base 201 installed at the bottom of the vehicle body 1. Two rotating boxes 206 are hinged to the bottom of the mounting base 201. The bottom of the rotating box 206 is provided with a side support wheel 205. The outer surface of the two rotating boxes 206 is provided with a diagonal bar 207. The ends of the two diagonal bars 207 away from the rotating box 206 are hinged to each other.

[0026] like Figure 3 as well as Figure 4 In this embodiment, a crossbar 202 is installed at the bottom of the vehicle body 1, and an L-shaped block is installed on the outer surface of the crossbar 202. An electric push rod 203 is hinged to the lower part of the L-shaped block. The output end of the electric push rod 203 is hinged to the hinged parts of the two diagonal bars 207. A protective plate 204 is installed on the outer surface of the electric push rod 203. The protective plate 204 reduces the impact of stones on the electric push rod 203 during the operation of the all-terrain vehicle. A self-locking mechanism is installed inside the electric push rod 203. The self-locking mechanism enables the electric push rod 203 to self-lock when the power is off, maintaining the current position of the load.

[0027] like Figure 4 as well as Figure 5 In this embodiment, the adjacent surfaces of the two rotating boxes 206 are hinged with limiting seats 208, and an inner support spring 209 is installed between the two limiting seats 208. The outer surface of the limiting seat 208 is provided with a protrusion, which is inserted into the inner support spring 209. This allows the inner support spring 209 to be limited by the limiting seat 208, preventing it from dislodging. The inner support spring 209 supports the rotating box 206, enabling the rotating box 206 to drive the lateral support wheel 205 to maintain an outward tilting support force to cope with sudden ground conditions.

[0028] like Figure 5In this embodiment, sleeves 210 are installed on the adjacent surfaces of the two limiting seats 208. One sleeve 210 is inserted into the inside of the other sleeve 210. The two sleeves 210 remain inserted as the rotating box 206 rotates. This ensures that when the sleeve 210 abuts against the outer surface of the limiting seat 208 on the other side, the limiting rotating box 206 cannot continue to rotate. At this time, the rotating box 206 rotates to a vertical state. When the inclined rod 207 rotates and drives the rotating box 206 to rotate outward to the maximum angle, the two sleeves 210 remain inserted, thereby protecting the internal support spring 209.

[0029] Furthermore, a hinge seat is movably mounted on the outer surface of the rotating box 206. The hinge seat can rotate on the outer surface of the rotating box 206, and the end of the diagonal rod 207 near the rotating box 206 is hinged to the rotating box 206 through the hinge seat. This allows the diagonal rod 207 to stably drive the rotating box 206 to rotate outward when pushed by the electric push rod 203, thereby adjusting the rotation angle of the rotating box 206 to adapt to different road conditions, providing stable lateral support force and preventing tipping. The connection relationship, working principle, and operation sequence between the electric push rod 203 and its internal self-locking mechanism and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0030] Example 2 Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 This is the second embodiment of the present invention, which is based on the previous embodiment. The adjustment component 3 is disposed inside the rotating box 206. The adjustment component 3 includes a threaded rod 306 movably installed inside the rotating box 206. The outer surface of the threaded rod 306 is engaged with a pressing disc 307. The side of the lateral support wheel 205 is movably mounted with a mounting block 302 via a rotating shaft. Two connecting plates 301 are mounted on the outer surface of the mounting block 302. The top of the connecting plate 301 passes through the bottom of the rotating box 206 and a support disc 309 is mounted thereon. A compression spring 308 is installed between the pressing disc 307 and the support disc 309.

[0031] like Figure 6 as well as Figure 7In this embodiment, a worm gear 304 is installed on the top outer surface of the threaded rod 306, and a worm 303 is movably installed inside the rotating box 206. The worm 303 is meshed with the worm gear 304. One end of the worm 303 passes through the outer surface of the rotating box 206 and is fitted with a rotating block 305. The rotating block 305 abuts against the outer surface of the rotating box 206 and provides a certain frictional force, so that the rotating block 305 itself cannot rotate, thereby preventing the worm 303 from rotating when not manually rotated. Furthermore, through the unidirectional transmission characteristic of the worm 303 and the worm gear 304, the position of the compression disc 307 is locked, ensuring that the preload adjustment of the contraction spring 308 can remain stable.

[0032] like Figure 6 as well as Figure 7 In this embodiment, the support plate 309 has a through hole that mates with the threaded rod 306, the outer surface of the extrusion plate 307 has a groove, and the inner wall of the rotating box 206 has a limiting protrusion that mates with the groove. Through the cooperation of the groove and the limiting protrusion, the extrusion plate 307 is prevented from rotating, thereby ensuring that the rotation of the threaded rod 306 can stably drive the extrusion plate 307 to rise and fall. The bottom end of the threaded rod 306 passes through the through hole inside the support plate 309 and is movably connected to the bottom of the inner cavity of the rotating box 206. Furthermore, the connecting plate 301 prevents the support plate 309 from rotating, thereby preventing the compression spring 308 from twisting due to the rotation of the support plate 309 and the extrusion plate 307, and ensuring that the compression spring 308 can work normally.

[0033] Furthermore, by turning the rotating block 305 with a wrench or other tools, the worm gear 303 is driven to rotate, which in turn drives the worm wheel 304 to rotate, which in turn drives the threaded rod 306 to rotate. This causes the extrusion disc 307 to move on the outer surface of the threaded rod 306. After the extrusion disc 307 moves, the extrusion force on the top of the compression spring 308 is adjusted, thereby adjusting the preload of the compression spring 308 to adapt to different driving conditions.

[0034] Working principle: When using the all-terrain vehicle, the hinged parts of the two inclined rods 207 are pushed by the electric push rod 203, which in turn drives the inclined rods 207 to rotate. The rotation of the inclined rods 207 drives the two rotating boxes 206 to rotate synchronously, thereby adjusting the rotation angle of the rotating boxes 206. During the rotation of the rotating boxes 206, the two limit seats 208 drive the inner support springs 209, thereby maintaining the inner support of the rotating boxes 206, providing auxiliary support, reducing the operating force of the electric push rod 203 on the rotating boxes 206, and ensuring that the rotating boxes 206 can be stably maintained at a certain angle. By adjusting the rotation angle of the rotating boxes 206, the angle of the side support wheels 205 can be adjusted, thereby achieving adaptability. To provide stable lateral support and prevent rollover under different road conditions, after adjusting the rotation angle of the rotating box 206, the preload of the retraction spring 308 is adjusted. By turning the rotating block 305 with a wrench or other tools, the worm gear 303 is rotated, which in turn drives the worm wheel 304 to rotate, which in turn drives the threaded rod 306 to rotate. This causes the compression disc 307 to move on the outer surface of the threaded rod 306. After the compression disc 307 moves, the compression force on the top of the retraction spring 308 is adjusted, thereby adjusting the preload of the retraction spring 308 to adapt to different driving conditions, and finally completing the lateral support adjustment of the all-terrain vehicle.
