Embodiment Construction
[0011] The main structure of the present invention is as figure 1 As shown, the six-wheel four-wheel drive obstacle-surmounting platform of the present invention is characterized in that the front wheel 1 and the rear wheel 10 are driving wheels, the middle wheel 11 is a driven wheel, and the servo motor 2 that controls the steering of the front wheels is connected with the rod 3 and the rod through the hinge. 4 connection, both ends of the rod 4 are not hinged, the rod 3 can rotate around the axis 5 and at the same time be fixed with the rod 6 by the screw, and the rod 6 and the rod 12 are connected by a hinge at the shaft 7, and the rod 12 and the intermediate wheel 11 Connected by a hinge, while the rod 12 is fixed at the shaft 7, so that the rod 12 and the rod 8 can rotate around the shaft 7 at the same time, the rod 8 is connected to the rod 21 through the hinge, and the rod 21 is connected to the servo motor 9 that controls the rear wheel steering through the hinge .

The invention relates to a six-wheeled four-wheel-drive obstacle crossing platform. The six-wheeled four-wheel-drive obstacle crossing platform comprises two driving wheel sets, a driven wheel set, a hinge multi-rod obstacle crossing mechanism and a vehicle, wherein the hinge multi-rod obstacle crossing mechanism is mounted on the vehicle; the two driving wheel sets are respectively mounted at two ends of the hinge multi-rod obstacle crossing mechanism; and the driven wheel set is mounted in the middle of the hinge multi-rod obstacle crossing mechanism. Each driving wheel set comprises front wheels and rear wheels, a control mode of each driving wheel is a double-servo-motor control mode, and one servo motor provides forward motion power while the other servo motor controls a steering angle of each driving wheel. By the hinge multi-rod obstacle crossing mechanism, positions of the various wheel sets relative to the vehicle can be adaptively adjusted according to a current road surface terrain, and therefore, a stable obstacle crossing purpose is achieved. Moreover, due to adaptive adjustment of the hinge multi-rod obstacle crossing mechanism, the forward motion direction of the rear wheels deviates to a certain degree, and the deviation amount is compensated by the servo motors which control steering of the rear wheels. The six-wheeled four-wheel-drive obstacle crossing platform is efficient in obstacle crossing and high in adaptability.
Description
technical field [0001] The invention belongs to the application field of obstacle-surmounting platforms, in particular to a hinged multi-bar obstacle-surmounting device, which belongs to the innovative technology in obstacle-surmounting platforms. Background technique [0002] Today, with the remarkable improvement of living standards, natural disasters have become the most harmful disasters to human beings. How to quickly search and rescue survivors in the ruins after a disaster and maximize the protection of people's lives and properties is a direction worth studying. [0003] No matter in the ruins, or in the wild environment that is more dangerous for human beings, or even in the future on alien planets, such as the moon, Mars, etc., these places will need machines to replace human beings to work, regardless of the ruins or the wild, the terrain must be It is random and diverse. In this environment, ordinary mobile obstacle-crossing platforms are no longer adaptable, so...
