Description

Technical Field

[0001] The present application relates to the technical field of unmanned vehicle chassis, specifically an all-terrain multifunctional unmanned vehicle chassis with full suspension, multiple wheels and multiple drives. Background Art

[0002] The unmanned vehicle chassis is the core hardware platform of autonomous vehicles, equivalent to the "skeleton" and "motor nervous system" of traditional cars. It is responsible for carrying key components such as sensors, computing units, and power systems, and providing basic functions such as vehicle movement, steering, and braking. Through electronic and intelligent design, it replaces the traditional chassis' dependence on manual operation and is the physical basis for realizing autonomous driving.

[0003] Multi-wheel and multi-drive unmanned vehicles can achieve greater carrying capacity and better power, but multi-wheel and multi-drive will also cause the unmanned vehicle's turning radius to become larger. In actual operation, the decline in steering ability will cause the unmanned vehicle to have difficulty turning in places where there is not much space.

[0004] In addition, the existing unmanned vehicle technology is based on the chassis height in terms of obstacle crossing.

[0046] The design of the rotating assembly C is the same as that of the rotating outer ring 211 , the second limiting block 212 , the first limiting block 210 and the rotating inner ring 209 .

[0047] The integrated control of the device is arranged inside the chassis 101 , and the chassis 101 also houses the power supply and other electronic components necessary for the operation of the device.

[0048] The bottom of the support frame 311 is rotatably connected to the bottom of the mounting base 301 , and the top mounting bearing of the support frame 311 can also be rotatably connected to the chassis structure 1 .

[0049] The distances between all the wheels on one side and the other side are equidistant arrays, and the specific number of wheels installed is 4-16 in even numbers.

[0050] Working principle:

[0051] Before using the device, first check all the major components of the device to ensure that the components of the device cooperate properly and that the device can work normally.

[0052] When the device is used, first the control unit installed in the chassis structure 1 powers the device via the battery.

[0053] When the user requires the device to make a U-turn, there are three optional U-turn modes: steering U-turn, radius U-turn and stationary U-turn. Steering U-turn causes the least wear on the tire. If space permits, steering U-turn is the first priority of the device. Radius U-turn causes greater wear on one of the tires. In a small space environment, radius U-turn is the second preferred U-turn mode. Stationary U-turn causes the most wear on the tire. In a small space, stationary U-turn is the third preferred option. The U-turn mode is selected according to the control unit installed inside the device.

[0054] Preferred steering U-turn:

[0055] When the device is turning around, the front and rear steering wheel assemblies 102 are not driven, and the steering system 103 controls one of the front and rear steering wheel assemblies 102 to turn to a suitable angle and is directly driven by the driver 314. The rotation of the driver 314 drives the driving gear 315 to rotate, and the rotation of the driving gear 315 drives the first driven gear 316 to rotate. The rotation of the first driven gear 316 drives the second driven gear 317 to rotate, and the rotation of the second driven gear 317 drives the transmission rod 319 to rotate. The transmission rod 319 drives the driving wheel 303 to rotate through the left and right bending transmission blocks 308, the first rotating rod, the second upper and lower bending transmission blocks 307, the second driving shaft 306, the first upper and lower bending transmission blocks 305, and the first driving shaft 304 to provide a power source for the device to realize the operation of the driving device. One of the front and rear steering wheel assemblies 102 realizes the guidance of the device and realizes the U-turn of the device. This U-turn method realizes the U-turn by the device performing an arc movement around the center of the circle.

[0056] Optimal radius U-turn:

[0057] When the device performs a radius U-turn, the two first electric telescopic rods 302 first drop slightly so that the U-turn system 3 supports the entire device. One of the lockers 310 works, and the second electric telescopic rod 3103 works first. The second electric telescopic rod 3103 works to push the isolation plate 3104 to move. The movement of the isolation plate 3104 pushes the hydraulic oil inside the hydraulic housing 3102 into the push-out housing 3106 through the transmission pipe 3105. The hydraulic oil pushes the push-out rod 3107 and the friction plate 3108 to lock the transmission rod 319. The transmission rod 319 that is locked is the transmission rod 319 closest to the steering center point. When one of the transmission rods 319 is locked, the motor 3183 is started, and 3083 works to make its sealing plate 3184 and the steering rod 3185 push the housing 3 181 moves, the steering rod 3185 moves to drive the steering ring 3186 to move, when the steering ring 3186 moves, it drives the first rotating rod to deviate left and right through the left and right bending transmission block 308, when the first rotating rod deviates, the second upper and lower bending transmission block 307, the second driving shaft 306, the first upper and lower bending transmission block 305, and the support frame 311 deviate, when the support frame 311 deviates, the driving wheel 303 is driven to deviate through the first driving shaft 304, when the deflection is completed, the two drivers 314 are started, and the two drivers 314 rotate to provide power for their device. Since one transmission rod 319 has been locked, when the three driving wheels 303 rotate, the device rotates around the locked driving wheel 303 to achieve a center point U-turn.

[0058] Prefer to make a U-turn on the spot:

[0059] When the device is turning in place, the two first electric telescopic rods 302 are first slightly lowered so that the turning system 3 supports the entire device. When turning in place, the four wheels are turned according to the upper steering requirement, and the two drivers 314 are started. The two drivers 314 rotate in different directions and output their power in two different rotation directions. The power output of the driver 314 located on the inner side of the rotation is backward, and the power output of the driver 314 located on the outer side of the rotation is forward. The amount of power output is selected by the integrated control, and the driving wheel 303 on one side rotates forward and the other side rotates backward, so that the device can make a circular motion around the center point of the device to achieve a rotating U-turn in place.

[0060] When the device is performing an obstacle-crossing operation, first, the two first electric telescopic rods 302 are completely lowered, so that the U-turn system 3 supports the entire device, the chassis 101 is lifted, the transmission rod 319 works, and the device is driven forward. When the front and rear steering wheel assemblies 102 of the device fall on the obstacle, the two first electric telescopic rods 302 are completely raised, so that the matching grooves 207 are matched with the matching heads 2012, the driver 314 rotates, and the driving gear 315 rotates. When the first limit block 210 is against the second limit block 212 and the two coupling blocks of the rotary assembly C are also matched, the power is transmitted. The power is transmitted to the first inclined plate through the first commutator 2011, the power transmission rod 202, the second commutator 204 and the power transmission column 206. Gear 2052, the first bevel gear 2052 drives the transmission shaft of the front and rear steering wheel assemblies 102 to achieve forward and backward drive, and the device continues to overcome the obstacle. When the U-turn system 3 is at the top of the obstacle, the driver 314 stops rotating first. When the driver 314 stops rotating, the counterweight block 208 at the bottom of the matching groove 207 causes the matching groove 207 to drive the rotating inner ring 209 to rotate within the rotating outer ring 211, and the rotary assembly C also rotates to reset. When the counterweight block 208 is vertical, the first electric telescopic rod 302 resets, disengaging its matching groove 207 from the matching head 2012, so that its power is no longer transmitted, and the driving wheel 303 contacts the obstacle. The driver 314 works to drive the driving wheel 303 to work, and the device achieves obstacle crossing.

[0061] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
