Accordingly, there is a need for an improvement over the prior art to overcome the deficiencies described in the prior art.
Disclosure of Invention
The purpose of this application is to provide a wheeled robot to solve among the prior art wheeled robot when the obstacle is avoided in the roll, if bump with the obstacle, lead to the robot to send great turning to easily, lead to the problem that the robot position was lost.
The purpose of the application is realized through the following technical scheme:
in a first aspect, a chassis assembly of a robot is provided, including a chassis body, the chassis body is circular structure, the chassis body is provided with running gear, running gear includes:
the driving wheel is a rear wheel and is arranged at the rear of the bottom of the chassis body;
the steering wheel is a front wheel and is arranged in front of the bottom of the chassis body.
Optionally, according to any embodiment of the first aspect of the application, the chassis assembly has a weight behind the chassis body that is greater than a weight in front of the chassis body.
Optionally, according to an embodiment of the first aspect of the present application, the driving wheel comprises a left driving wheel and a right driving wheel, and the left driving wheel and the right driving wheel are disposed opposite to each other.
Optionally, according to an embodiment of the first aspect of the present application, the steering wheel comprises a left steering wheel and a right steering wheel, the left steering wheel and the right steering wheel being oppositely disposed.
Optionally, the chassis assembly according to any embodiment of the first aspect of the present application, the steering wheel is a universal wheel.
In a second aspect, a robot structure is provided, comprising:
a chassis assembly according to any embodiment of the first aspect of the present application;
and the airframe component is arranged above the chassis body.
The beneficial effect that this application embodiment reached: this application is with the front wheel of steering wheel as the robot, when the robot met the barrier and dodges, even the chassis body touched the barrier, also can make the robot body turn away smoothly under the assistance of steering wheel because the steering wheel sets up in the place ahead to avoid the barrier.
In addition, the weight at the rear of the chassis body is larger than the weight at the front of the chassis body, so that the gravity center of the whole robot body leans backwards, and the steering wheel serving as the front wheel can easily overcome the obstacle when the robot surmounts the obstacle, so that the whole robot body can surmount the obstacle stably.
Drawings
Fig. 1 is a schematic structural view of a chassis assembly provided in one embodiment of the present application.
In the figure, a chassis body 1, a travelling mechanism 2, a driving wheel 21 and a steering wheel 22.
Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
When the robot has an obstacle in front and the robot touches the obstacle, at present, the robot generally takes the driving wheel as the front wheel, when the robot keeps away the obstacle, the robot cannot turn well, so that the robot rubs with the obstacle to generate opposite force, if the opposite force is large, the robot can turn at a large angle in the obstacle avoidance process, so that the position of the robot is lost, or the robot is inclined, the obstacle is difficult to avoid and the like.
Aiming at the technical problems, the application provides a chassis assembly of a robot and a robot structure.
Fig. 1 shows a schematic structural diagram of a chassis assembly of a robot according to an embodiment of the present application, as shown in fig. 1, the chassis assembly includes a chassis body 1, the chassis body 1 is provided with a traveling mechanism 2, and the traveling mechanism 2 includes: a driving wheel 21 and a steering wheel 22.
The driving wheel 21 is connected with a walking motor, and the walking motor drives the driving wheel 21 to rotate so as to drive the robot to walk. The steering wheel 22 is connected with a steering motor, and the steering motor drives the steering wheel to act, so that the robot steers.
The driving wheel of this embodiment is the rear wheel, installs in the rear of chassis body bottom. The steering wheel is a front wheel and is arranged in front of the bottom of the chassis body.
In this embodiment, the steering wheel is used as the front wheel of the robot, when the robot encounters an obstacle to avoid, even if the chassis body touches the obstacle, the steering wheel is arranged in front, so that the robot body can smoothly turn away under the assistance of the steering wheel to avoid the obstacle.
It is understood that the driving wheels comprise a left driving wheel and a right driving wheel, and the left driving wheel and the right driving wheel are oppositely arranged at the left side and the right side of the rear part of the bottom of the chassis body.
The steering wheels comprise left steering wheels and right steering wheels, and the left steering wheels and the right steering wheels are oppositely arranged at the left side and the right side in front of the bottom of the chassis body.
It will be appreciated that the front in this embodiment refers to the end facing the direction of travel of the robot and the rear refers to the end facing away from the direction of travel of the robot.
It should be noted that, the terms "upper," "lower," "left," "right," "front," "rear," and the like in the present application refer to an orientation or a positional relationship based on the orientation or the positional relationship shown in the drawings, and are merely for convenience of describing the present application and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
With respect to the above technical problems, it can be understood that the weight of the chassis body in the present embodiment is greater at the rear than at the front.
The weight at the rear of the chassis body is greater than the weight at the front of the chassis body, so that the gravity center of the robot is at the rear, when the robot surmounts the obstacle, the front steering wheel can easily surmount the obstacle, and then the driving wheel surmounts the obstacle, so that the whole robot body can surmount the obstacle stably.
It can be appreciated that the weight deviation between the rear of the chassis body and the front of the chassis body is within a preset range, and the weight deviation can enable the robot to run stably when crossing an obstacle.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
