Problems solved by technology

[0003] The general-purpose wheeled chassis generally adopts a four-wheel structure, which is fast on hard roads and has strong maneuverability. However, due to the high grounding pressure, it is prone to slipping, subsidence, and inability to overcome in non-structural environments such as mud, sand, and slopes. Obstacles or even rollovers

Embodiment 1

[0025] Embodiment 1: as figure 1 , figure 2 As shown, a terrain adaptive mobile chassis includes a large wheel assembly, a small wheel assembly, a linkage mechanism 16, and a frame 6, wherein the large wheel assembly includes a first large wheel 13, a second large wheel 19, a first large wheel The bull wheel connecting rod 12, the second bull wheel connecting rod 21, the first spring 8, the third spring 20, the small wheel assembly includes the first small wheel 10, the second small wheel 14, the first small wheel connecting rod 9, the first small wheel Two small wheel connecting rods 17, the linkage mechanism 16 includes the first connecting rod 1, the second connecting rod 2, the third connecting rod 3, the fourth connecting rod 4, the fifth connecting rod 5, the base 11, and the load-bearing rod 7. Both ends of the support rod 15 are respectively connected with the third connecting rod 3;

[0026] The first bull wheel 13 is hinged with one end of the first bull wheel con...

Embodiment 2

[0031] Embodiment 2: as figure 1 , figure 2 As shown, a terrain-adaptive mobile chassis adopts a left-right symmetrical structure, adding elastic damping devices to the left and right wheels, and adding a linkage mechanism to the front and rear wheels to improve the terrain-adaptive ability of the mobile chassis in an unstructured environment, thereby ensuring the mobility of the chassis. Stability of chassis operation.

[0032] The structures on both sides of the moving mechanism are connected by support rods 15, wherein the two ends of the support rods 15 are respectively hinged with the connecting rods 3 on each side, as figure 2 shown.

[0033] When the mobile chassis provided by the present invention crosses obstacles, climbs slopes or is in other non-structural environments, under the action of the linkage mechanism and the big wheel support spring, the four wheels can self-adaption match the road conditions, so that the four wheels can effectively contact the ground...

Abstract

The invention discloses a movable chassis with terrain adaptability and belongs to the technical field of machinery. The movable chassis adopts a left-right symmetrical structure and is characterized in that link gears on the left side and the right side are both six-bar linkage mechanisms which are connected through connecting rods; two small wheels are arranged on the front side and the back side of the movable chassis and are universal wheels; two large wheels are arranged on the left side and the right side of the movable chassis and connected with a rack through compression rings. The movable chassis has the advantages that the obstacle crossing capability, the motion stability and the rollover resistance of the movable chassis can be improved substantially; the movable chassis is concise in structure and high in practicability, has better portability and can be applied to quadricycles, mobile robots and the like.

Description

technical field [0001] The invention relates to a terrain self-adaptive mobile chassis, which belongs to the technical field of machinery. Background technique [0002] At present, the passability of the mobile chassis is one of the most important performances for ground vehicles such as cars and robots, especially when operating in an unstructured environment, the chassis is required to have good flexibility and adaptability. Therefore, improving the passability of the chassis in complex terrain environments has always been a hot topic of research by experts and scholars at home and abroad. At present, for different road conditions in complex terrain, the mobile chassis used mainly include wheeled, tracked and legged structures. Among them, the crawler chassis has better grip ability on soft ground, but the speed is slower and the power is higher; the leg chassis can meet some special performance requirements, but the structure is complex, there are more degrees of freedom...
