Patent Application
20180050747
This application and its disclosure generally relate to the field of wall climbing vehicles.
Wall climbing vehicles are generally known in the industry. For example, U.S. Pat. No. 7,520,356 discloses a mobile robot having two suction modules and a hinge assembly pivotally connecting the suction modules together. The suction modules generate a vacuum suction force securing the mobile robot to the climbing surface. In use, however, the suction portions accumulate dirt and, consequently, loose the suction force causing the mobile robot to fall.
It is an object of the present invention to provide a multi-terrain, tracked, wall climbing, multipurpose vehicle.
In its general aspect, the invention is a multi-terrain wall climbing vehicle including a generally rectangular housing having a top opening and a bottom opening. A power source is placed within the housing. A first motor and a second motor are located within the housing and are connected to the power source. At least four pairs of wheels are connected to the housing, at least two of the wheel pairs being connected to and powered by the first motor. Two tracks are placed onto the wheels so as to surround the housing to enable the vehicle to ride along a riding surface. A propeller is placed within the housing between the top opening and the bottom opening. The propeller is connected to the second motor. As the propeller rotates, it draws in air from at least one of the top opening and the bottom opening and exhausts the air through the top opening so as to generate an adhesion force enabling a secure connection between the tracks of the vehicle and the riding surface.
In one of its specific aspects, the multi-terrain vehicle is provided with an attachment mechanism secured to the housing and configured to attach a mobile phone and/or a camera to the vehicle.
The invention is illustrated by way of examples which are not a limitation, and the figures of the accompanying drawings in which references denote corresponding parts, and in which:
As illustrated in the attached Figures, the vehicle of the present invention is capable of going over multiple types of surfaces, easily transitioning from the floor to the wall and to the ceiling.
As shown in
The vehicle also includes two non-motorized pairs of wheels: a third pair of wheels 16 and a fourth pair of wheels 18. Each of the non-motorized wheels is connected to one of the motorized wheels by rods 22. Alternatively, wheels 16 and 18 can also be motorized by connecting them to the motor 6. All wheels on one side are connected with a track 20. The track connects the wheels attached to the motor and the wheels connected through the rods, so that the wheels attached to the motor spin the wheels on the rods, therefore spinning the entire track.
A second motor 24 is secured to the rectangular housing 2 in the center of the vehicle. The second motor 24 is connected to the power source 8 via a separate set of wires 28. A propeller 26 is mounted on and connected to the second motor 24. As the power is supplied from the power source 8 to the second motor 24, the second motor spins the propeller 26. The propeller is exposed at the top and the bottom of the vehicle through housing openings 32 and 34. In the preferred embodiment, the assembly of the second motor 24 and the propeller 26 is secured to the rectangular housing 2 by motor mounting rods 36.
In use, as the propeller 26 rotates, it draws in air through the bottom opening 32 and/or through outer perimeter of the top opening 34, and then exhausts the air from the center of the top opening 34, thus generating an adhesion force F, which is perpendicular to and is directed away from the bottom surface of the vehicle. additionally, the direction of the force F is perpendicular to the direction of the vehicle's movement D. In the preferred embodiment, the propeller 26 is specifically adapted so that the adhesion force F is greater than the gravity force applied to the vehicle 10, to ensure a continuous contact of the tracks 20 with the riding surface. Accordingly, as shown in
As shown in
Compared to the prior art vehicles, the vehicle of the present invention has superior wall climbing capabilities on a tougher terrain and a simplified design. The internal components of the vehicle are not only protected by the housing, they're also protected by the tracks, which surround the rectangular housing on both sides and keep it off the ground. The tracks allow the vehicle to flip over and even to drive over a rough and inaccessible terrain. In addition to proving a strong suction power, which allows the vehicle to climb vertical surfaces and even transition to an upside down position, the propeller keeps dust and other particles away from the internal components. The vehicle's simple design also allows for various accessories, such as cameras and sensors, to be attached to it. Lastly, various wireless devices, e.g., a mobile phone or a camera, can be attached to the attachment mechanism 38.
The vehicle of the present invention can be used as a surveillance vehicle, a military vehicle, or as a photography vehicle. Any surveillance or photo accessories can be placed on the vehicle's housing. The simple design of the vehicle will ensure that any anti surveillance equipment such as jammers will not have a significant affect. The propeller can also be designed to provide a minimal amount of noise, so the vehicle couldn't be heard. The military uses for the vehicle are similar. The vehicle can be modified to hold weapons and supplies, and it can access previously inaccessible areas. Lastly, the vehicle can be used for rescue purposes. It can deliver first aid supplies to victims who cannot be accessed due to harsh terrain. If the vehicle flips over, either due to severe weather or a ground disturbance, it will still keep its mobile abilities due to the specially designed tracks.
Unlike other vehicles, which have vacuum suction mechanisms, which get jammed due to dust, this vehicle has a propeller which will not get obstructed by dust, and the vehicle will continue to have its adhesive abilities. The vehicle can be modified for any other fields which require access to harsh or inaccessible terrain. In addition, it can be used for leisure purposes such as video or photo applications, by attaching photo or video equipment, e.g. a mobile phone, to the vehicle.
In the preceding specification, the invention has been described with reference to specific exemplary embodiments thereof. It will however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the claims that follow. For example, instead of providing a single top opening and a single bottom opening, a plurality of smaller vents can be provided at the top and the bottom surface of the rectangular housing. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.
