Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

An electric motor car inner tube that combines that fig. 1 to fig. 2 show, including inner tube of a tyre body 1, inner tube of a tyre body 1 is inside to be aerifyd layer 2, be provided with enhancement layer 3 between inner tube of a tyre body 1 and the layer 2 of aerifing, aerify the inside strutting arrangement 4 that is provided with of layer 2, strutting arrangement 4 includes support ring 401 and lower support ring 402, it sets up in the upper portion of aerifing layer 2 to go up support ring 401, lower support ring 402 sets up in the lower part of layer 2 of aerifing, it is provided with a plurality of springs 403 to the array to go up between support ring 401 and the lower support ring 402, it nevertheless contactless to press close to enhancement layer.

The reinforcing layer 3 is made of epoxy resin, namely epoxy resin is coated on the inner surface of the inner tube body 1, and the preferred material is epoxy resin because the epoxy resin has certain toughness and elasticity and low cost; the inner tube body 1 is provided with an air tap 5 communicated with the inflatable layer 2; the sections of the upper support ring 401 and the lower support ring 402 are semi-circular arcs, so that the semi-circular arcs are matched with the inner surface of the inner tube body 1; the upper support ring 401 and the lower support ring 402 are made of metal materials or alloy materials or high polymer materials, the support effect is good, and the cooperation with the spring 403 can ensure that the inner tube body 1 can still normally run and has a certain elastic shock absorption effect under the condition that the inner tube body is punctured.

The working principle is as follows: when the inflatable tire is used, the inflatable layer 2 is filled with air through the air tap 5, at the moment, the upper support ring 401 and the lower support ring 402 in the support device 4 are close to the reinforcing layer 3 but are not in contact with the reinforcing layer 3, the support device 4 and the tire tube body 1 normally rotate during driving, the arranged reinforcing layer 3 can reduce the probability that sharp objects such as nails and the like puncture the tire tube body 1, and the service life of the tire tube is prolonged; when a sharp object breaks through the inner tube body 1 and the reinforcing layer 3, air in the inflating layer 3 leaks, the upper supporting ring 401 and the lower supporting ring 402 are simultaneously contacted with the reinforcing layer 3, the inner tube body 1 is supported, the whole electric vehicle is supported by the whole supporting device 4, the spring 403 arranged between the upper supporting ring 401 and the lower supporting ring 402 can play a role in damping in the running process of the electric vehicle, and then the electric vehicle is driven to a repair shop for repair.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
