Robotic obstacle crossing device
View Patent ↗A robotic obstacle-crossing device mainly includes a wheel body and an obstacle-crossing body, wherein the wheel body includes a wheel part, a first obstacle-crossing part and a second obstacle-crossing part. When the sweeping robot tilts, the plurality of first recessed portions and the plurality of second recessed portions provided on the periphery of the first obstacle-crossing part and the second obstacle-crossing part provide a climbing function. In addition, when the sweeping robot encounters obstacles or steps, the obstacle-crossing body can provide robot the function of the obstacle-crossing or climbing, thereby reducing the number of situations when the sweeping robot is trapped or unable to effectively climb upon encountering an obstacle or a steep road surface.
1. A robotic obstacle-crossing device, comprising:
a robot;
at least one wheel body, being disposed at a bottom position of the robot, and the wheel body comprises:
a wheel part;
a first obstacle-crossing part, being disposed on one side of the wheel part, and a plurality of first recess portions arranged on the periphery of the first obstacle-crossing part; and
a second obstacle-crossing part, being disposed on another side of the wheel part, and a plurality of second recess portions arranged on the periphery of the second obstacle-crossing part.
2. The robotic obstacle-crossing device of claim 1 , wherein the inside of the first recessed portion is provided with a plurality of first fastening portions, with each of the first fastening portions being configured to engage with a solid.
3. The robotic obstacle-crossing device of claim 1 , wherein the second recessed portion is provided with a plurality of second fastening portions, each of the second fastening portions being configured to engage with a solid.
4. The robot obstacle-crossing device according to any one of claim 1 , wherein the first recessed portion is interlaced with the set position of the second recessed portion.
5. The robot obstacle-crossing device of claim 1 , comprising a driving device connected to the wheel body, the driving device driving the wheel body to rotate.
6. A robotic obstacle-crossing device, comprising:
a robot;
at least one wheel body, being disposed at a bottom position of the robot; and
at least one obstacle-crossing body, being disposed at a bottom position of the robot, and adjacent to the wheel body, the periphery of the obstacle body being provided with a plurality of groove portions;
wherein, the position of the obstacle-crossing body is higher than the wheel body, when the periphery of the wheel body is in contact with a plane, the periphery of the obstacle-crossing body is a distance away from the plane.
7. The robotic obstacle-crossing device of claim 6 , wherein the wheel body comprises:
a wheel part;
a first obstacle-crossing part, being disposed on one side of the wheel part, and the first obstacle-crossing part being provided with a plurality of first recess portions; and
a second obstacle-crossing part, being disposed on another side of the wheel part, and the second obstacle-crossing part being provided with a plurality of second recess portions.
8. The robotic obstacle-crossing device of claim 7 , wherein the first recessed portion is interlaced with the set position of the second recessed portion.
9. The robotic obstacle-crossing device of claim 6 , comprising:
a linkage body, being coupled to the wheel body and the obstacle-crossing body, to allow the wheel body and the obstacle-crossing body being simultaneously actuated.
10. The robotic obstacle-crossing device of claim 9 , wherein the linkage body is provided with a gear set, the gear set comprising:
a wheel body driving wheel, being connected with the wheel body;
a connecting driven wheel, being peripherally meshed with the wheel body driving wheel, and the connecting driven wheel rotating in opposite direction to the wheel body driving wheel; and
an obstacle-crossing driven wheel being coupled to the obstacle-crossing body, the periphery of the obstacle-crossing body driven wheel meshing with the connecting driven wheel, and the obstacle-crossing driven wheel rotating in opposite direction to the connecting driven wheel.
11. The robotic obstacle-crossing device of claim 6 , wherein the first groove portion is internally provided with a plurality of third fastening portions, each of the third fastening portions being provided to engage with a solid.
