The embodiment of the invention provides a mobile device, which can be an autonomous mobile device, such as a cleaning robot, a accompanying robot, a meal delivery robot and the like; the mobile device may also be a remotely operated mobile device, such as a remote controlled toy car, a remote controlled monitor car, or the like.
Fig. 1 is a side cross-sectional view of a mobile device 10 according to an embodiment of the present invention, showing only a simple structure of the mobile device 10. The mobile device 10 includes: the traveling wheel 200, the motor 300, the lifting member 400, and the body 100. In this embodiment, the moving device 10 includes a universal wheel 500 and two running wheels 200, and the motor 300 drives the running wheels 200 to rotate so as to drive the body 100 to move on the ground. Fig. 1 shows only one running wheel 200, and it is easy to understand that two running wheels 200 are symmetrically arranged, each running wheel 200 may be driven by a respective corresponding motor 300, and each running wheel 200 may be provided with a corresponding lifting member 400. In other embodiments, the mobile device 10 may also include three or four travel wheels 200.
For convenience and brevity, the components of the running wheel 200, the motor 300, the lifter 400, and the like, which are illustrated in the drawings, are explained below.
The body 100 is provided with a limiting part, the lifting piece 400 is provided with a movable end 410, a contact part 420 and an eccentric position 430, and the contact part 420 is positioned between the movable end 410 and the eccentric position 430. The lifting member 400 is eccentrically and swingably connected to the running wheel 200 via an eccentric position 430, the movable end 410 is slidably connected to the stopper portion, and the contact portion 420 protrudes outward beyond the rolling surface 201 of the running wheel 200 in the moving direction R. In this embodiment, the limiting portion includes a limiting chute 110, the movable end 410 has a limiting slider 411, and the limiting slider 411 penetrates into the limiting chute 110. In other embodiments, the limiting portion includes a limiting slider, the movable end 410 is provided with a limiting chute, and the limiting slider penetrates into the limiting chute.
In the embodiment shown in fig. 1, when the motor 300 drives the running wheel 200 to rotate, the running wheel 200 drives the lifting member 400 to eccentrically swing, so that the limit slider 411 and the limit chute 110 relatively slide.
The process of applying the mobile device 10 shown in fig. 2 to 5 to climb a step S is described as an example of a process suitable for crossing various types of obstacles.
FIG. 2 is a schematic view of the contact portion 420 of the lifter 400 overlapping the edge of the step S; fig. 3 is a schematic view of the traveling wheel 200 of the mobile device 10 being suspended by the lift 400. In the process of changing the moving device 10 from fig. 2 to fig. 3 along the moving direction R, the running wheel 200 rotates clockwise CW to drive the lifting element 400 to eccentrically swing, and under the lifting action of the lifting element 400, the running wheel 200 is lifted to be suspended.
Fig. 4 is a schematic view of the case where the rolling surface 201 of the road wheel 200 contacts the step S under the action of the lifter 400. In the course of the change from fig. 3 to fig. 4, the running wheel 200 continues to rotate in the clockwise direction CW, and the rolling surface 201 of the running wheel 200 can come into contact with the contact step S under the grip force of the lifting piece 400.
Fig. 5 is a schematic view of the traveling wheel 200 climbing up the step S by the lift 400. In the course of the change from fig. 4 to fig. 5, the running wheel 200 continues to rotate in the clockwise direction CW, and the running wheel 200 can finally climb up the step S under the supporting action of the lifter 400 and the rolling friction of the rolling surface 201 of the running wheel 200 with the step S.
Fig. 6 is a schematic structural view of the lifter 400 shown in fig. 1, wherein the lower portion of the contact portion 420 has a contact surface, and in this embodiment, the lifter 400 between the movable end 410 and the eccentric portion 430 is bent downward to form the contact portion 420. The contact surface may be a planar structure 421 shown in fig. 6, or may be an arc surface structure 421' shown in fig. 7; the shape of the contact surface can be changed in various ways according to the actual application, and the contact surface is not limited. The contact surface is at least partially formed of a soft material, such as a rubber material.
Referring again to fig. 1, in this embodiment, a road wheel 200 includes a hub 210 and a tire 220 supported by the hub 210, the tire 220 having a rolling surface 201. The lifter 400 is eccentrically swingably coupled to the hub 210 via an eccentric location 430. In other embodiments, running wheel 200 may also be constructed of an integrally formed wear resistant material.
In an alternative embodiment, the eccentric portion 430 includes a positioning hole, and a positioning protrusion protruding from the hub 210 at a position offset from the rotational axis 21A thereof, the positioning protrusion penetrating into the positioning hole, and the positioning protrusion being rotatably connected with respect to the positioning hole.
In another alternative embodiment, the eccentric portion 430 includes a positioning projection having a positioning hole formed in the hub 210 at a position offset from the rotational axis 21A thereof, the positioning projection penetrating into the positioning hole, the positioning projection being rotatably coupled with respect to the positioning hole.
For a more visual and intuitive understanding of the meaning of "the contact portion 420 protrudes outward beyond the rolling surface 201 of the running wheel 200 in the moving direction R", it can be seen from the reference to fig. 1 to 5: the portion of the contact portion 420 near the movable end 410 protrudes outward beyond the rolling surface 201 of the running wheel 200, that is, the contact portion 420 protrudes outward beyond the rolling surface 201 of the running wheel 200 in the moving direction R, thereby facilitating the crossing of an obstacle.
Figures 8-11 are side cross-sectional views of the mobile device 10 with the lift 400 in four exemplary positions. As can be easily seen from fig. 8 to 11, the contact portion 420 will not contact the ground all the time during the process of driving the body 100 to move on the ground when the running wheel 200 rotates, so that the normal running of the mobile device 10 on the ground will not be affected.
As shown in fig. 12, in the embodiment of the present invention, the mobile device 10 may further include a pivoting arm 600 and a spring 700, wherein one end of the pivoting arm 600 is pivoted to the body 100, and in particular, one end of the pivoting arm 600 is pivoted to the body 100 through a pivoting shaft 610. The running wheel 200 is rotatably connected to the other end of the pivoting arm 600, the springs are respectively connected to the body 100 and the pivoting arm 600, and the other end of the pivoting arm 600 always has a tendency to rotate toward the outside of the body 100 under the elastic force of the springs. In this embodiment, the motor 300 is fixedly mounted to the pivoting arm 600. The specific structural design can be referred to in the patent specification and the drawings of the 201420621549.8 application number for description of the driving wheel module, and the description is omitted herein.
The moving device 10 provided by the embodiment of the invention comprises a body 100 provided with a limiting part, a running wheel 200, a motor 300 and a lifting piece 400 provided with a movable end 410, an eccentric position 430 and a contact part 420 positioned between the movable end 410 and the eccentric position 430, wherein the lifting piece 400 is eccentrically and swingably connected to the running wheel 200 through the eccentric position 430, the movable end 410 is slidably connected with the limiting part, and the contact part 420 protrudes outwards beyond the rolling surface 201 of the running wheel 200 along the moving direction R, so that the running wheel 200 can cross higher obstacles after being lifted under the action of the lifting piece 400 and is suitable for smoothly moving on uneven ground.
