Detailed Description

The utility model is described in further detail below with reference to the figures and specific examples. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and distinctly aiding in the description of the embodiments of the utility model.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

Example 1

Referring to fig. 1 to 5, the core of the present invention is to provide a tire comprising a tire body 1 and a plurality of bladder assemblies 3.

The outer lane of tire body 1 is equipped with annular child pipe 2, the inside cavity of

child pipe

2, and 3 circumference equipartitions of a plurality of gasbag subassemblies are in child pipe 2. Every gasbag subassembly 3 all includes three inside cavity and is full of

gaseous polyhedron gasbag

4, and 4 one end interconnect of three polyhedron gasbags, the other end are connected in the 2 inner walls of child pipes, support child pipe 2 through a plurality of gasbag subassemblies 3.

The polyhedral cells 4 are close to a sphere but have a large area of mutual contact with the inner wall of the tube 2, and the contact surfaces generate effective friction to improve the stability of the cooperative framework of each individual polyhedral cell 4 in the cell module 3. And the polyhedral air bag 4 not only has the high bearing capacity of a sphere, but also has the high stability of large-area contact.

The polyhedral airbag 4 in the present embodiment is a dodecahedron, and preferably a regular dodecahedron. The dodecahedron is close to a sphere, but has larger contact area, and high bearing capacity and high stability are both considered.

The adjacent surfaces of the three polyhedral air bags 4 of the single air bag component 3 are mutually jointed and connected to form a honeycomb structure, and the three polyhedral air bags 4 respectively occupy 120-degree angles.

In the present embodiment, the airbag module 3 includes 81 and 243 polyhedral airbags 4 in total. 81 air bag assemblies 3 formed by 3 polyhedral air bags 4 are orderly and uniformly fixed in the tyre tube 2. Thus, when one polyhedral air bag 4 is punctured, the other polyhedral air bags 4 can still normally bear the pressure from the weight of a rider and the dead weight of a bicycle.

Furthermore, the outer wall of the tire tube 2 far away from the circle center side is covered with a replaceable outer tire layer in a sticking mode through glue, the outer tire layer is replaceable, so that a wheel hub does not need to be detached from the frame 7 during repair, then the tire is separated, tire repair can be directly carried out on the surface of the tire, and the tire repair is very convenient. And cover tyre layer including wearing and tearing layer 5 and suggestion layer 6, wearing and tearing layer 5 is used for contacting ground, and suggestion layer 6 is located between wearing and tearing layer 5 and child pipe 2, and the colour and the wearing and tearing layer 5 of suggestion layer 6 are different, can remind the user to change, prevent further wearing and tearing child pipe 2.
