Problems solved by technology

[0003] In order to solve the disadvantages that the cylindrical stepless adjustment mechanism of the leg length of the lower limb rehabilitation robot cannot be completely locked, and the step length adjustment mechanism cannot fully adapt to the change of the patient's leg length, the invention provides an exoskeleton leg length Adjustment mechanism, the invention designs the thigh rod with a rectangular cross-section structure and uses the principle of sleeve pulling, which not only meets the requirement of being able to completely lock the length, but also realizes the function of stepless adjustment

Embodiment 1

[0019] see Figure 1-2 , the present embodiment provides an exoskeleton leg length adjustment mechanism, including a thigh rod 1, the thigh rod 1 has a rectangular cross-section, and the thigh rod 1 is divided into two parts: an upper thigh rod 11 and a lower thigh rod 12. The thigh bar 11 is connected with the lower thigh bar 12 through a U-shaped sleeve 2, specifically the upper thigh bar 11, the lower thigh bar 12 and the U-shaped sleeve 2 are all provided with a strip notch, and the lower thigh bar 12 is nested into the U-shaped sleeve 2, and the long notch on the lower thigh bar 12 cooperates with the long notch on the U-shaped sleeve 2 to connect through the first push-pull quick clamp 3, that is The first push-pull quick clamp 3 connects the lower thigh rod 12 and the U-shaped sleeve 2 through the elongated notch on the lower thigh rod 12 and the U-shaped sleeve 2; the upper thigh rod 11 is nested Put it into the U-shaped sleeve 2, and the long notch on the upper thigh...

Embodiment 2

[0021] The exoskeleton leg length adjustment mechanism provided in this embodiment has the same general structure as that of Embodiment 1, the difference is that a spacer 5 is added to the first push-pull quick clamp 3 and the second push-pull quick clamp 4, Such as figure 1 shown for increased clamping force.

Abstract

The invention discloses an exoskeleton leg length adjusting mechanism. The exoskeleton leg length adjusting mechanism comprises a thigh rod, wherein the thigh rod is divided into an upper thigh rod body and a lower thigh rod body; the upper thigh rod body and the lower thigh rod body are connected through a U-shaped sleeve; specifically, the upper thigh rod body, the lower thigh rod body and the U-shaped sleeve are each provided with a long-strip-shaped notch; the lower thigh rod is nested in the U-shaped sleeve, and the strip-shaped notch formed in the lower thigh rod is matched with the strip-shaped notch formed in the U-shaped sleeve, and is connected with the strip-shaped notch formed in the U-shaped sleeve through a first push-pull type rapid clamp; and the upper thigh rod is nested in the U-shaped sleeve, and the long-strip-shaped notch formed in the upper thigh rod is matched with the long-strip-shaped notch formed in the U-shaped sleeve and connected with the long-strip-shapednotch formed in the U-shaped sleeve through a second push-pull type rapid clamp. By means of the two push-pull type rapid clamps, the locking function of the adjusting mechanism is achieved, and relative movement between the U-shaped sleeve and the thigh rods is limited by means of push-pull rods of the rapid clamps.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation robots, and in particular relates to an exoskeleton leg length adjustment mechanism. Background technique [0002] The leg length adjustment mechanism of lower limb rehabilitation robots is generally divided into stepless adjustment type and step adjustment type, while the existing stepless adjustment type is usually cylindrical. When the length of the cylindrical adjustment mechanism is fixed due to the shape, the lock The tightening force will be broken down by the cylindrical wall, resulting in incomplete locking. When the cylindrical adjustment mechanism is subjected to a large pulling force, it will twist, resulting in a change in length. Although the step-adjustable type has a special-shaped cross-section shape and can solve the problem of twisting, it cannot meet the needs of stepless adjustment according to the different leg lengths of patients, and cannot well adapt to the patient...
