Running machine based on internet and internet competition system

The invention provides a running machine based on an internet and an internet competition system. The internet running machine comprises a running platform, a main control device, a network module and a damper, wherein the running machine adopts an arc caterpillar-type running platform of which the front and rear ends are higher and the middle part is lower, initiative running is formed by virtue of the gravity action, the impact injury on knee joints is reduced, the damper can limit the highest motion speed, and the motion safety is further guaranteed. The running speed is correspondingly adjusted by virtue of the foot settling speed of a runner, so that the foundation of a competition is realized. By combining the network module, a mobile terminal and a cloud platform, various participating running machines are interconnected to form a network, so that the running machines distributed in different places in the world can participate in the network competition in real time, the main control device generates a virtual image of each competitor and transmits the virtual image to a virtual-reality terminal, each competitor stands on a corresponding position according to the data information of the corresponding running machine, and a competition result is pushed to the mobile terminal in real time. By virtue of the internet competition, the reality, challenge, fun and sociability of the body building by utilizing the running machine can be improved, and the body building impetus and the body building effect can be improved.

Exercise realization method, client and server

An embodiment of the invention discloses an exercise realization method, a client and a server, and is to enhance enjoyment and enthusiasm of a user when the user does physical exercises alone. The method comprises the following steps: the client receives pair exercise request information, initiated by the user, of a target pair exercise item; the client sends the pair exercise request information to the server to enable the server to judge whether a preset pair exercise condition is met according to the pair exercise request information; if the preset pair exercise condition is met, the client receives a pair exercise response message sent by the server; the client starts a pair exercise function according to the pair exercise response message and obtains real-time exercise data of a target body part of the user collected by an intelligent wearable device, wherein the intelligent wearable device is in communication connection with the client; the client sends the real-time exercise data to the server; and the client receives real-time pair exercise information fed back by the server according to the real-time exercise data, and outputs the real-time pair exercise information in a target pair exercise scene to enable the user to adjust the real-time exercise data according to the real-time pair exercise information.

Transforming puzzle

A puzzle assembly is shown and comprises a multiplicity of geared links that are arranged such that their turning axes are oriented along the edges of a polyhedral shape so that when a single link is turned, all links turn synchronously. In the assembly, there are two end positions of the geared links. In each end position, a set of link groups are formed, each of those groups corresponding to one face of the polyhedral shape so that each link group forms a circular track that is inscribed on that particular face. When the puzzle assembly is moved to a second end position, a new set of new link groups is formed corresponding to a different a different set of faces of the polyhedral shape. The puzzle assembly further comprises a number of “petal elements” equal to the number of geared links. The petals have a faceted form and a base piece that extends from that form for providing a sliding contact with the geared links. Each petal element is retained by a geared link. When the puzzle assembly is in one end position, a group of petals corresponding to a polyhedral face touch each other to form a pyramidal shape. Thus, one-half of their surfaces are exposed and one-half of their surfaces are hidden. When the puzzle assembly is “flipped”—the geared links are turned to their other end position—the petals recombine to hide the previously visible surfaces and to reveal the previously invisible surfaces. Importantly, in either end position, the group of petals corresponding to a polyhedral face may be twisted around the center point of that face, thereby changing the correspondence between the geared links and the petal elements.
