Description

Technical Field

[0001] The utility model relates to a wheel-track interchange structure, in particular to a wheel-track interchange structure for an all-terrain robot. Background Art

[0002] An all-terrain wheeled robot refers to a robot that can travel on any terrain. It can move freely on terrains where ordinary vehicles are difficult to maneuver. All-terrain robots have multiple uses and are not restricted by road conditions. When all-terrain vehicles are used in special scenarios such as swamps or sand, traditional wheels cannot pass smoothly. Since the contact area of a single tire is small and the ground pressure is strong, the tire will sink into the swamp or sand. Chinese patent document: CN202410126068.8, discloses a mountain hybrid extended-range wheel-track interchangeable all-terrain tractor. This application uses a detachable matching track, with wheels as driving wheels, and drives the track to travel on complex terrain. When the electric steering mechanism is locked, the steering is achieved by the motor to control the forward and reverse direction of the wheel. The track can be disassembled on flat land such as dry land, and the electric steering mechanism is unlocked at the same time, and the wheels are used for walking. This application Figure 6 The interlocking structure shown in the figure drives the track displacement by interlocking the cone-shaped pattern structure in the middle of the wheel with the circular groove in the middle of the track. However, on gravel or deep snow sections, foreign objects may clog the track grooves, and the foreign objects in the grooves cannot be discharged by themselves, resulting in the cone being unable to be smoothly embedded in the grooves on the track, ultimately affecting the normal driving of the vehicle.

[0025] See also Figure 1-6This embodiment provides a wheel-tire interchangeable structure for an all-terrain robot, including a vehicle body 1, with two sets of wheels 2 connected to both sides of the vehicle body 1, each set of wheels 2 being driven by a separate motor, each set of tires including a front wheel and a rear wheel, wherein the front wheel can be steered by a steering system. The cam 32 is provided with a plurality of tooth blocks 31 on the inner wall of the track 3, and each tooth block 31 is detachably mounted on the inner surface of the track 3. The tooth blocks 31 are composed of a plurality of convex tooth blocks 32 arranged at equal intervals, and each convex tooth block 32 is detachably mounted on the inner surface of the track 3 by fasteners. A groove 33 is formed between two adjacent convex tooth blocks 32. The two side surfaces of the convex tooth blocks 32 are inclined surfaces, and the two sides of the groove 33 are gradually narrowed from the outside to the inside. The surfaces of the wheels 2 are arranged with raised patterns, and both sides of the patterns extend to the edge and form convex strips 21 that are adapted to the grooves 33 on both sides of the track 3. The convex strips 21 are engaged with the grooves 33 to realize the insertion and positioning of the wheels 2 and the track 3. The continuous rotation of the tire makes the convex strips 21 on the tire engage with the grooves 33 in turn, and finally the wheels 2 drive the track 3 to operate.

[0026] Both sides of the protruding tooth block 32 are arc surfaces for the end of the protruding tooth block 32 close to the tire, so that one end of the protruding tooth block 32 is fitted with the side of the tire and the protruding tooth block 32 is covered on the side of the tire to play a positioning and protection role.

[0027] Wheeled mode is suitable for high-speed movement on hardened roads, while Track 3 mode provides better traction and stability on soft or uneven ground. In Track 3 mode, steering is achieved by two drive motors controlling the two sets of wheels 2 to rotate in the forward and reverse directions respectively.

[0028] There is at least one detachable position on the crawler 3. Both ends of the crawler 3 at the detachable position are provided with a hinge group 35 made of metal material. A number of hinge seats are arranged horizontally on the hinge group 35. The hinge seats 36 on the two hinge groups are staggered, so that the two hinge components at both ends of the crawler 3 are embedded with each other through the hinge seats and the pin rod 37 passes horizontally through the pin holes on the two hinge groups 35 to realize the disassembly and connection of the crawler 3.

[0029] When installing the crawler 3, unfold the two crawlers 3 and place them flat on the ground. Then align the tires on both sides of the robot with the two crawlers 3 and drive onto the two crawlers 3 so that the convex strips are aligned with the embedded grooves. Then, put the crawler 3 on each set of tires. Then, use the clamping tool 4 to clamp the two ends of the crawler 3 and put them close together until the hinge seats on its hinge group 35 are aligned one by one, so that the pin holes of each hinge hole are aligned. Finally, insert the pin rod 37 from one side so that the pin rod 37 passes through each hinge seat. The end of the pin rod 37 can be tightened and positioned by a nut, and finally the installation connection between the crawler and the wheel is realized.

[0030] This quick installation / disassembly mechanism enables the conversion between wheels to be completed in a short time, avoiding long downtime.

[0031] This wheel-track interchange structure can be applied in the following fields:

[0032] -Military and Security: Perform reconnaissance and missions in various terrains, quickly switching modes to adapt to different battlefield environments.
