Embodiment

[0045] like figure 1 As shown, the portable wheeled mobile device provided by this embodiment has a stepping propulsion mechanism, including a car body 1, four wheels 2 of the same size, and two stepping propulsion wheels installed on the front and rear parts of the car body 1. Institutions 3 and 4.

[0046] like figure 2 As shown, the stepping propulsion mechanism and the video camera device are in a folded state when the vehicle is transported, the swing rocker arms 3-1 and 4-1 of the stepping propulsion mechanism are folded in the middle of the car body at the edge position, and the stepping support 3 -2 and 4-2 are then folded into the same direction as the swing rocker arms 3-1 and 4-1 and stretch out along the side, and all drive units of the stepping propulsion mechanism are all braked. The video camera device 5 is folded and fixed on the upper wall of the car body. In the wheeled state, the mobile device moves forward and backward through the wheels 2, and turns thro...

Abstract

The invention relates to the technical field of robots or unmanned cars, in particular to a portable wheel type shifter with stepping propulsion mechanisms. The stepping propulsion mechanisms are installed on the front portion of the portable wheel type shifter of a car body and the rear portion of the portable wheel type shifter of the car body, when the wheel type shifter moves, the stepping propulsion mechanisms are folded inwards to be placed in the middle of the car body, when the wheel type shifter needs to cross obstacles, rocker arms are swung and unfolded and swung to proper positions, the wheel type shifter crosses steps and ditches and climbs stairs through continuous rotation of a stepping support, and accordingly the portable wheel type shifter has the capacity for adapting to complex terrain.

Description

technical field [0001] The invention relates to the technical field of robots or unmanned vehicles, in particular to a portable wheeled mobile device with a stepping propulsion mechanism. Background technique [0002] The wheeled propulsion system has the advantages of high efficiency, high speed, and stability on flat roads, but its obstacle clearance performance is poor on unstructured roads such as mountains, swamps, soft ground, and stairs. The crawler propulsion system has the advantages of strong adaptability to different terrains and low ground pressure, but it has high friction, high energy consumption and poor maneuverability. The foot propulsion system has good adaptability to different terrains, and has good passability on uneven roads such as mountains and gravel roads, but has disadvantages such as complex structure and control, poor stability, and low efficiency. The above three propulsion methods have their own advantages and disadvantages. [0003] In order...
