Problems solved by technology

In the case of different lengths of the track, the tension force on the driving wheel is different, resulting in different friction driving force, so there is a possibility of slipping, which also brings difficulties to the design of the track a

Embodiment 1

[0033] Refer to attached figure 1 , 2 , 3, 7, 8:

[0034] The technical solution adopted by the present invention to solve its technical problems is:

[0035] The stretchable and deformable elastic track includes the outer track 1, the inner track 2 and the connecting joint 3, which are integrally processed and formed by non-metallic elastic materials through a mold. The outer track 1 is a serpentine spring structure, and the whole is in a closed ring shape , its side end surface is wavy in the initial state; the inner crawler 2 is a serpentine spring structure, and the whole is in a closed ring shape, and its side end surface is wavy in the initial state; the inner crawler 2 and the outer crawler 1 are concave , the convex and curved sections are arranged at intervals, and the number of concave and convex bends of the two is the same, the width of the inner crawler 2 is smaller than the width of the outer crawler 1; the inner crawler 2 is set inside the outer crawler 1, and...

Embodiment 2

[0044] Refer to attached Figure 4 :

[0045] The present invention is integrally processed and shaped by a non-metallic elastic material through a mold, so the initial state of the present invention can be processed into different shapes, Figure 4 It is a perspective view of the second embodiment of the present invention whose initial state is a round rectangle. The structure of the second embodiment can refer to the first embodiment.

Embodiment 3

[0047] Refer to attached Figure 5 , 6 :

[0048] In the present embodiment three, a connecting support block 12 connecting the two is provided between the outer convex section 1 4 of the outer crawler belt 1 and the outer convex section 2 5 of the inner crawler belt 2, as Figure 5 shown. Adopt this technical scheme, when the present invention expands, as Image 6 As shown, the connection support block 12 between the outer crawler belt 1 and the inner crawler belt 2 makes the present invention have better support, making it more adaptable to uneven ground.

Abstract

The invention discloses an elastic caterpillar band capable of realizing telescopic deformation. The elastic caterpillar band comprises an outer layer caterpillar band (1), an inner layer caterpillar band (2) and linkage sections (3), and is formed by integrally processing a non-metallic elastic material through a die; the outer layer caterpillar band and the layer caterpillar band are both of a snakelike spring structure; the inner layer caterpillar band is narrower than the outer layer caterpillar band, and is arranged in the outer layer caterpillar band; the linkage sections are respectively arranged at middle parts of all concave segments I (6) of the outer layer caterpillar band and all concave segments II (7) of the inner layer caterpillar band; each linkage section comprises an outer tooth (8), a linkage segment (10) and an inner tooth (9); the outer teeth and the inner teeth are respectively arranged on the outer wall and the inner wall of the outer layer caterpillar band; the linkage segments are arranged between the outer layer caterpillar band and the inner layer caterpillar band and are connected with the outer layer caterpillar band and the inner layer caterpillar band; a guide slot (11) is arranged between each inner tooth and the inner layer caterpillar band. According to elastic caterpillar band disclosed by the invention, the number of layers of the inner layer caterpillar band can be reduced or increased as needed; when being in an initial state, the elastic caterpillar band disclosed by the invention becomes long after bent convex-concave segments are expanded under the action of an external supporting force; after the external force is removed, the elastic caterpillar band can be restored to the initial state, and therefore the telescopic deformation is realized.

Description

technical field [0001] The invention relates to a stretchable and deformable elastic crawler, which belongs to the research field of crawler walking mechanism for mobile platforms. Background technique [0002] The crawler-type walking mechanism has good terrain adaptability and terrain passability, and has strong obstacle surmounting ability, so it has been widely used in small mobile robots. Sometimes the scheme of actively or passively changing the shape of the track is adopted to make the tracked mobile robot obtain better obstacle-surmounting performance. At present, there are two common ways to change the track shape: joint track deformation and track self-deformation. The former uses a plurality of crawler units to articulate to form a joint crawler robot, such as a two-swing arm four-track robot (such as the crawler form in a patent application with a publication number of CN201179899), a four-swing arm six-track robot, by changing the joint track (swing arm) The a...
