A walking assist device has a frame, fixed handles, rails provided with movable handles, front wheels, rear wheels and that serve as drive wheels, drive units, a battery, and a drive control unit, and travels forward or rearward together with a user that walks while grasping the fixed handles or the movable handles. The walking assist device has an operation mode switching unit that switches between a training mode, in which a load is applied to operation of the body of the user performed as the user walks, and an assist mode in which a load on operation of the body of the user performed as the user walks is alleviated.

The present invention is directed to an autonomous exoskeleton device that includes one or more actuators, one or more controllers, one or more sensors with one or more unidirectional transmissions. The present invention provides a mechanical joint in parallel with a biological joint. The exoskeleton device preferably includes and electric motor and winch, chain, belt, cam transmission or other mechanism for providing unidirectional force to assist rotation about the biologic joint. Moreover, a controller, a motor angle sensor, joint angle sensor and/or force sensor may be used for additional control and monitoring of the device. The motor may be any type of motor, but is preferably brushless in configuration where its diameter is larger than its length to provide a compact and lightweight exoskeleton device.

An exoskeleton device is provided herein that includes a control unit having at least one actuator. A transmission assembly operably couples the control unit to a hinged assembly. A sensor is coupled to the hinged assembly and is configured to acquire data in reference to use of the hinged assembly. The exoskeleton device also includes a feedback modality. A controller is in communication with the sensor and feedback modality. The controller is configured to activate the feedback modality based on a measured performance metric that is determined from the acquired data.

A powered exoskeleton is designed to provide assistance to a user, where the powered exoskeleton may have power-generating elements in one location and power-applying elements in another location, so that a user can easily wear the powered exoskeleton.

A drive mechanism, a massage mechanism and a massage gun are provided and belong to the technical field of power transmission. The drive mechanism includes: a drive motor; a first eccentric wheel, an end surface thereof fixedly connected to an output shaft of the drive motor and another end surface thereof provided with a first eccentric shaft; a drive lever, arranged on a side of the first eccentric wheel facing away from the drive motor and an end thereof being assembled with the first eccentric shaft by a first bearing; a second eccentric shaft, assembled on another end of the drive lever facing away from the first eccentric shaft; a second eccentric wheel, assembled with the second eccentric shaft by a second bearing and an end thereof facing away from the second eccentric shaft being provided with a fixing part; and a transmission piston, pivotally connected with the drive lever.

A hand-held massage device includes a housing, a first turning plate, a second turning plate, an output rod, and a driving assembly. The housing includes an opening. The first turning plate is accommodated in the housing. The first turning plate has a concave-convex surface. The second turning plate is disposed between the opening and the first turning plate. The output rod is inserted in the second turning plate and rotated with the second turning plate. One end of the output rod is inserted to the opening and another end is abutted to the concave-convex surface. The driving assembly is connected to the first turning plate and the second turning plate. The driving assembly drives the first turning plate to rotate, drives the second turning plate to rotate or simultaneously drives the first turning plate and the second turning plate to rotate.

Various features for improving the performance of crutches are provided. A crutch can flex at one or more locations or include composite material to provide energy storage and return to the user during ambulation. In some aspects, a crutch is provided that can propel the user forward during ambulation. The crutch can be hollow at one or more locations to allow for increased flexibility and narrower at one or more locations to enhance springiness of the crutch.

An apparatus for toning an exerciser's buttocks comprises, a base having a front end region and a rear end region; a seat guide; and a force-transmitting mechanism for supporting the seat guide on the base for guided movement under tension from a raised position, along an forward inclined trajectory in which the seat guide is continuously lowered in elevation to a lowered position. The exerciser sits on the seat guide and controls its downward and upward motion by tensioning and thereby exercising the users gluteus maximus, medius, and gluteus minimus muscles.

An improved impact massager includes two impact force modules and a main circuit board in a chassis. An electromagnetic component and a cushioning element are coaxially provided in a heat sink of each impact force module. A drive rod of a drive component group is connected to an impact rod. A coupler of a transmission assembly is connected to the coupling seat with an oscillating coil provided therein and electrically connected with the main circuit board. When the oscillating coil and the magnetic core ring are coaxially positioned and displaced with respect to each other, the magnetic core ring does not interact with the oscillating coil, no current is generated by the oscillating coil and the main circuit board is in a power-off state, such that no power is transmitted to the electromagnetic component and motions are inhibited under no-load condition.

A mat transmission structure includes a first body, multiple first operation units, and a power unit. The first body is provided with a first recess and multiple first pivot portions. Each of the first operation units is pivotally mounted on each of the first pivot portions. Each of the first operation units includes a rod, multiple first operation members, and a first driving member. The rod is provided with a first fitting portion, two first pivoting sections, and a first mounting portion. Each of the first operation members is provided with a first surface and a second fitting portion. The first driving member is mounted on the first mounting portion. The power unit drives the first driving member of each of the first operation units such that each of the first operation units is rotated in the first recess.
