Along with the raising continually developing utilization and people's life requirement of new forms of energy, as the battery-driven car of basic walking-replacing tool, be almost seen everywhere from rural area to city.But it is well-known, after tire on automobile is punctured, automobile can also continue to travel longer distance, so that find Automobile Service center to keep in repair, and the tire of battery-driven car is once be punctured, then inevitably to expend time in and manpower goes for repair location and remedies.If the tire on battery-driven car is punctured, the gas in a few second in tire will all leak, and battery-driven car can not normally be walked, and gently then needs spended time and strength to push battery-driven car and finds maintenance point, heavy then may cause unnecessary trouble.So, provide a kind of stable performance and cheap tire is very necessary.For bicyclist, tire of good performance can either improve the safety performance of battery-driven car entirety, can avoid inconvenient maintenance again; For manufacturer, anti-tie tire can improve the competitive power of battery-driven car in competitive market.

At present, also have the anti-puncturing tyre of some bilayers, but these tires are after being punctured, need to inflate the spare tire in tire with Floor Pump, if be not with Floor Pump, spare level still can not use, and effectively can not solve battery-driven car by the technical matters of pricking.

Utility model content

The utility model overcomes the deficiency that prior art exists, and aim to provide a kind of structure simple, cheap, anti-tie performance is good, and can improve the electric vehicle tyre of safety.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the anti-tie electric vehicle tyre of novel practical, comprise cover tire and the inner tube of a tyre, the inner tube of a tyre is placed in the space that cover tire and wheel rim flange ring formed, anti-prick ply is provided with in the inner tube of a tyre, anti-prick ply is elastic material, and the inner tube of a tyre is divided into the first separate space and second space by anti-prick ply, and the volume in the first space is much smaller than the volume of second space.After inflation, the first space is identical with the air pressure in second space, is in relaxed state because anti-prick ply is only subject to slight gravity.

After sharp object punctures cover tire and the inner tube of a tyre, gas in first space can leak gradually, air pressure reduces, because anti-prick ply is elastic material, anti-prick ply outwards expands, after anti-prick ply contacts with the termination of sharp object, cannot continue to stretch out in the position of encountering sharp object, other positions of anti-prick ply all can stretch out and be adjacent to cover tire, in this course, sharp object is wrapped gradually, sharp object can not puncture anti-prick ply, gas in first space all leaks, but the gas in second space can not leak, because the gas compartment in second space is far longer than the gas compartment in the first space, total gas pressure in tire only can reduce sub-fraction, therefore battery-driven car can continue normal operation.

Wherein, wheel is also furnished with the first valve port and duaspiracle mouth, first valve port is connected with the first space by rubber tube, duaspiracle mouth is connected with second space, and when giving this tyre inflating, the charging connector be divided into two by is inflated, in gas replenishment process, because the first valve port communicates with duaspiracle mouth, namely the first space communicates with second space, thus ensure that the first space is identical with the air pressure of second space.

Wherein, anti-prick ply is elastomeric quality of rubber materials, cheap, good practical effect.

The utility model compared with prior art has following beneficial effect: in the process that battery-driven car travels, if the inner tube of a tyre is punctured, due to the existence of anti-prick ply, battery-driven car when without any need for also can continue when service tools use, provide great convenience, thoroughly solve battery-driven car by the worry of pricking.

In figure: 1 is cover tire, 2 is the inner tube of a tyre, and 3 is anti-prick ply, and 4 is the first valve port, and 5 is duaspiracle mouth, and 6 is sharp object, and 7 is the first space, and 8 is second space.

Detailed description of the invention

Be described in further detail the utility model by reference to the accompanying drawings now, accompanying drawing is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, as everyone knows, in traditional electric vehicle tyre, the inner tube of a tyre 2 is one deck rubber belt, due to the air pressure in the inner tube of a tyre 2, the inner tube of a tyre 2 is close on cover tire 1, so after cover tire 1 is entered by nail or other sharp objects 6 bundle, the inner tube of a tyre 2 is easy to almost be punctured with cover tire 1 simultaneously, at short notice, gas in the inner tube of a tyre 2 can leak rapidly, and namely battery-driven car enters state of paralysis, cannot continue normal forward.In the utility model, provide the tire of band in a kind of bilayer, not only in traditional inner tube of a tyre 2, one deck anti-prick ply 3 has been added, anti-prick ply 3 is pliable and tough rubber material (as tied up to the rubber material on arm during transfusion), the inner tube of a tyre 2 is made to be divided into the space that two pressure is identical, i.e. the first space 7 and second space 8.

As Figure 2-3, when the rubber-tyred roller travelled is pressed onto the sharp object 6 of nail class, sharp object 6 wears out cover tire 1 and after the inner tube of a tyre 2 pressed close to cover tire 1, gas leak in first space 7, gas in second space 8 can stretch out gradually, in the process extended, the position of encountering sharp object 6 due to anti-prick ply 3 cannot stretch out, and the inwall extending out to cover tire 1 can be continued in other positions, in this process, sharp object 6 is wrapped up gradually by anti-prick ply 3, thus sharp object 6 cannot continue to wear out anti-prick ply 3, finally, gas in first space 7 is all discharged, but the gas in second space 8 can not leak, because the volume in the first space 7 is much smaller than the volume of second space 8, so after the gas leak in the first space 7, gas in second space 8 uses as spare tire, although the total gas pressure in tire can reduce a bit relatively, but can not affect tire continue move ahead, very practical.

Anti-prick ply 3 urgent need when the inner tube of a tyre 2 punctures, belongs to Emergency tyre, after finding maintenance point, can repair the inner tube of a tyre 2, and such anti-prick ply 3 also can continue to use as Emergency tyre, namely realizes reusable function.

Wherein, wheel is also furnished with the first valve port 4 and duaspiracle mouth 5, first valve port 4 is connected with the first space 7 by rubber tube, duaspiracle mouth 5 is connected with second space 8, and when giving this tyre inflating, the charging connector be divided into two by is inflated, in gas replenishment process, because the first valve port 4 communicates with duaspiracle mouth 5, namely the first space 7 communicates with second space 8, thus ensure that the first space 7 is identical with the air pressure of second space 8.

By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
