Detailed Description
In order that the present disclosure may be more readily and clearly understood, reference is now made to the following detailed description taken in conjunction with the accompanying drawings.
As shown in fig. 1, the cabin cleaning robot based on the electromagnetic principle comprises a driving wheel, an electric brush lantern ring 1, an electromagnet coil 2, a coaxial hinge 3, a connecting shaft 4, a support 5, a central platform 6, a water gun 7 and universal supporting wheels. The water gun 7 is arranged at the bottom of the central platform 6. The central platform 6 is fixedly connected with the two brackets 5 and the electric brush lantern rings 1 at the left side and the right side through screws. The two electric brush lantern rings 1 are respectively nested on the left connecting shaft 4 and the right connecting shaft 4, and the two connecting shafts 4 are connected through the coaxial hinge 3. The other ends of the two connecting shafts 4 are fixedly connected with the driving wheel. A plurality of electromagnet coils 2 are fixed on the inner ring of the driving wheel. Each electromagnet coil is in contact with and electrically conductive with a brush on the brush collar 1. Two universal supporting wheels are respectively arranged at the front end and the rear end of the bottom of the central platform 6.
The driving wheel comprises a driving wheel inner ring 8 and a driving wheel outer ring 9 which are matched through a sliding groove and can rotate relatively.
The universal supporting wheel comprises a universal wheel 10 and a spring 11, the universal wheel 10 is installed on the central platform 6 through the spring 11, and when the universal wheel 10 is extruded, the spring 11 contracts, so that the robot adapts to the cabin wall surface with radian.
The lantern ring part of the electric brush lantern ring 1 and the driving wheel inner ring 8 are made of insulating materials, and the central platform 6, the support 5 and the connecting shaft 4 are made of conductive materials.
A plurality of conducting strips 12 are assembled between the driving wheel inner ring 8 and the connecting shaft 4 and are uniformly distributed in the driving wheel inner ring 8 in a circumferential manner.
An electrode 13 is arranged at the tail part of the central platform 6 and supplies power to one end of the electromagnet coil 2 sequentially through the central platform 6, the bracket 5, the connecting shaft 4 and the conducting strip 12.
Each brush lantern ring 1 is provided with two brushes, namely an attachment brush 14 and a forward brush 15, which are in contact with and conduct electricity with one end of the electromagnet coil 2, and the four brushes of the left brush lantern ring 1 and the right brush lantern ring 1 are connected to four I/O ports of the controller respectively.
Except carrying on squirt 7 on the robot, can also carry on other work instruments, equipment, and in other use occasions, the theory of operation of this robot can satisfy other operation requirements, accomplishes different work.
The working principle of the invention is as follows:
for the sake of illustration, the two brushes on the brush collar 1 are named separately, the brush facing the cabin wall is the attached brush 14, and the brush facing forward with a certain inclination is the forward brush 15, as shown in fig. 1.
(1) When the robot is statically attached to the metal wall
The forward brushes 15 on both the left and right sides are not energized, and no attraction force is generated. The left and right sides of the attached brush 14 are powered on to generate magnetic attraction, so that the robot can be attached to the wall surface.
(2) When the robot needs to advance
The left and right sides depend on the brush 14 all to be switched on, make the robot can depend on the wall, keep the gesture stable, when needing to go forward, the brush 15 that goes forward of left and right sides all switches on, produces the appeal, makes the action wheel front end receive pressure, then the left and right sides depends on brush 14 outage, makes the action wheel roll forward under the effect of front end pressure. At the moment, the connecting shaft 4 and the driving wheel roll relative to the wall surface, and the central platform 6, the supporting frame and the electric brush lantern ring 1 move horizontally relative to the wall surface. Because the lantern ring does not rotate along with the driving wheel, the electromagnet originally connected with the advancing electric brush slides away from the advancing electric brush when the driving wheel rotates and is closed with the attached electric brush, the attached electric brush is electrified at the moment, so that the robot is attached to the wall surface of the cabin, and the robot can move forwards by alternately powering on and powering off.
(3) When the robot needs to turn
Taking the left turn of the robot as an example, the left and right attached brushes 14 are electrified, so that the robot can be attached to the wall surface to keep stable posture, the left advancing brush 15 is not electrified, the left driving wheel stops at the original position, the right advancing brush 15 is electrified, the right wheel rolls forwards, and the robot turns left by utilizing the differential principle. At this time, the connecting shafts 4 on the left and right sides rotate relatively.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
