Upper Limb Rehabilitation Robot Device

Upper Limb Rehabilitation Robot Device

This technology is an upper limb rehabilitation robot that combines a multi-joint link structure, a connecting shaft, and an actuator to assist with or provide resistance to rehabilitation exercises based on the user's upper limb trajectory.

Existing upper limb rehabilitation robots have struggled to integrate various movement types—such as horizontal, inclined, and vertical—and multifunctional training modes—such as active, passive, and resistive—into a single device.

This technology features a link unit, an active actuator (motor), a passive actuator (variable damper), and a rotatable connecting support, allowing for diverse exercise modes and multi-angle rehabilitation training tailored to the user's upper limb movement trajectory. It can be applied to rehabilitation training, gait assistance, and medical/welfare services, improving both the variety of rehabilitation exercises and cost-efficiency for patients with damaged or paralyzed limbs.

Key Features:

• A link unit with one side coupled to a connecting shaft and the other side equipped with an upper limb connector to secure the patient's arm.
• An upper limb rehabilitation robot device where a ball plunger is installed at the junction of the third and fourth rods.
• A base frame with a laterally positioned connecting support rotatably installed on one side.
• A connecting shaft rotatably installed on one side of the connecting support.
