Multifunctional mechanical exoskeleton

The invention discloses a multifunctional mechanical exoskeleton which comprises a fixing assembly, hip joint assemblies, thigh assemblies, knee joint assemblies, shank assemblies, ankle joint assemblies, pedal assemblies and walking wheel assemblies which are sequentially connected. Each walking wheel assembly comprises a walking wheel linear driver, a walking wheel support, a first rotary driver and a walking wheel; and each walking wheel linear driver is installed on the corresponding shank assembly, each walking wheel support is connected with a telescopic rod of the corresponding walking wheel linear driver, each walking wheel and the corresponding first rotary driver are both installed on the corresponding walking wheel support, each first rotary driver drives the corresponding walking wheel to rotate, and each walking wheel linear driver drives the corresponding walking wheel support to move up and down so that the corresponding walking wheel can be higher or lower than the corresponding pedal assembly. According to the mechanical exoskeleton, the walking wheel assemblies are arranged on the shank assemblies, the mechanical exoskeleton has the walking function and the self-walking function through the walking wheels capable of moving up and down, a user can conveniently move in different environments, and the action efficiency of the mechanical exoskeleton is improved.
