Description

Technical Field

[0001] This utility model relates to the field of self-propelled structures, and more specifically to a novel adaptive terrain track structure. Background Technology

[0002] Depending on the load and terrain, existing engineering machinery and industrial equipment employ different walking structures. Among them, tracked structures are often used for movement when the road is rugged and the load is heavy.

[0003] Chinese utility model patent CN222310764U discloses an all-terrain adjustable contour-following mobile chassis. This chassis includes a chassis body, a front drive axle mechanism, and a rear drive axle mechanism, with four triangular track wheels. An adjustment limiting plate is installed between the triangular track wheels and the drive motor, allowing the triangular track wheels to rotate at a certain angle relative to the ground. However, in actual use, it was found that these triangular track wheels can only be adjusted in the left-right direction of the chassis, and cannot be adjusted in the front-back direction, resulting in poor terrain adaptability.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem that track wheels in the prior art cannot be adjusted in the forward and backward directions, this utility model provides a novel adaptive terrain track structure. The novel adaptive terrain track structure includes: a track assembly, comprising a track frame, a drive structure mounted on the track frame, and a track structure connected to the drive structure; a swing arm, hingedly connected to the track frame; and shock-absorbing springs, at least two in number, arranged along the length of the track assembly on both sides of the swing arm.

[0006] This invention relates to an adaptive terrain tracked structure, comprising a track assembly and a swing arm. The swing arm is connected to the platform chassis. The track assembly includes a track frame, a drive structure, and track structures. The track frame mounts the drive structure and track structures and is connected to the swing arm. The drive structure drives the track structures, enabling the track assembly to move. The track assembly and the swing arm form a hinged connection, allowing the track assembly to adjust its angle in the longitudinal direction of the chassis around the swing arm as an axis, thus adapting to different terrain environments, such as uphill and downhill. Shock-absorbing springs are connected at both ends to the swing arm and the track frame, respectively, and are arranged on both sides of the swing arm. These springs limit the swing angle of the track assembly, preventing excessive tilting, and also allow the track frame to return to its original position after an uphill or downhill climb. Through these features, this invention provides an adaptive terrain tracked structure that allows the track assembly to adjust its angle in the longitudinal direction of the chassis around the swing arm as an axis, thereby adapting to different terrain environments.

[0007] Furthermore, the swing arm includes a first arm, a second arm arranged opposite to the first arm, and a connecting arm connecting the first arm and the second arm; the shock-absorbing springs are provided in two sets, and the two sets of shock-absorbing springs are respectively connected to the first arm and the track frame, and the second arm and the track frame.

[0008] Furthermore, mounting plates are provided on the first and second support arms, and hinge seats are provided on the track frame. One end of the shock-absorbing spring is hinged to the mounting plate, and the other end is hinged to the hinge seat.

[0009] Furthermore, a fixed seat is provided on the track frame, and a hinge shaft is installed on the fixed seat. The first support arm and the second support arm are hingedly connected to the hinge shaft. Elastic retaining rings are embedded at both ends of the hinge shaft.

[0010] Furthermore, the drive structure includes a drive wheel and a driven wheel rotatably mounted on the track frame, and a motor that drives the drive wheel to rotate; the track structure meshes with the drive wheel and the driven wheel.

[0011] Furthermore, the driven wheel is adjustablely mounted on the track frame, and a tensioner connected to the driven wheel is provided on the track frame.

[0012] Furthermore, pipe clamps are provided on the track frame.

[0013] Furthermore, a support roller is also provided on the track frame, and the support roller abuts against the track structure.

[0014] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0015] (1) The track assembly and the swing arm form an articulated connection, which allows the track assembly to adjust the angle of the swing arm as the axis in the front and rear directions of the chassis, thereby adapting to different terrain environments, such as uphill and downhill.

[0016] (2) The two ends of the shock-absorbing spring are connected to the swing arm and the track frame respectively, and are arranged on both sides of the swing arm. It can limit the swing angle of the track assembly, prevent the track assembly from tilting too much, and drive the track frame to reset after going uphill or downhill. Attached Figure Description
