Description

self-inflating tire

technical field

The utility model relates to the technical field of wheels, in particular to a self-inflating tire for electric bicycles and motorcycles.

Background technique

The wheel and the inflation device of the existing vehicle are two unrelated objects when they are not applicable, and the wheels and the inflation device are only connected when the tire is inflated, and the inflation device is used to inflate the deflated tire. Inflatable devices are usually too bulky to be carried around. Usually electric bicycles, electric tricycles and motorcycles often have air leakage during use and cannot be ridden. They can only be carried out, which brings great inconvenience to users. There is no good solution at present.

Utility model content

The purpose of this utility model is to address the above-mentioned deficiencies in the prior art, and provide a self-inflating tire that can inflate the tire at any time when the tire is deflated, and at the same time use the vehicle-mounted power supply to quickly supply air to the tire.

The technical scheme of the utility model is realized in the following way: the self-inflating tire includes a tire, an inner tube and a rim, and the rim is equipped with a miniature air cylinder, and the miniature air cylinder includes an air cylinder body, a piston, an air intake check valve, and an inflation check valve. And the air pump, the air cylinder body of the miniature air cylinder is fixed on the rim, and the air cylinder body is equipped with a spring that can push the piston to move outward quickly. After the block is compressed, it is reset by the spring so that the gas enters the inner tube of the tire from the air intake check valve on the other side of the air cylinder body; The outlets of the pumps are connected, and the air pump is also provided with a power supply interface.

Further, the air pump is a micro air pump, and the micro air pump is fixed on the body of the air cylinder.

Further, the rim is a steel rim.

Further, the air pump is sealed and connected with the body of the air cylinder.

Further, the compression block includes a limit block located outside the gas cylinder body and a movable rod capable of moving inside the gas cylinder body.

After the utility model adopts the above structure, when there is no air leakage, riding is the same as a normal tire without any uncomfortable feeling, and it will work only when there is air leakage, so that the tire can maintain a constant pressure, and there is no need for tires Worry about inflating; at the same time, it can use the vehicle power supply to quickly charge the tires, easy to use, no need to stop to replenish air, low manufacturing cost, and strong practicability.

Description of drawings

The utility model will be further described in detail below in conjunction with the embodiments in the accompanying drawings, but it does not constitute any limitation to the utility model.

Fig. 1 is a schematic structural view of the self-inflating tire of the present invention.

In the figure: 1-outer tire, 2-inner tube, 3-wheel rim, 4-inflator body, 5-spring, 6-compression block, 7-air pump, 8-power supply interface.

detailed description

Referring to shown in Fig. 1, the self-inflating tire of the present utility model comprises cover tire 1, inner tube of a tire 2 and rim 3, and miniature air cylinder is housed on the rim 3, and miniature air cylinder comprises air cylinder body 4, piston, air intake one-way valve, inflation valve To the valve and air pump 7, the air cylinder body 4 of the miniature air cylinder is fixed on the rim 3, the spring 5 that can push the piston to move outward quickly is housed in the air cylinder body 4, the piston is located in the air cylinder body 4 and the piston rod of the piston is connected to compress Block 6, the compression block 6 is located inside the inner tube 2, and the compression block 6 is reset by the spring 5 after being compressed so that the gas enters the inner tube 2 of the tire from the air intake check valve on the other side of the gas cylinder body 4; An inflation check valve is provided, and the inflation check valve is connected with the outlet of the air pump 7, and the air pump 7 is also provided with a power supply interface 8.

Air pump 7 is micro air pump 7, and micro air pump 7 is fixed on the air cylinder body 4.

The rim 3 is a steel ring.

Air pump 7 is airtightly connected between cylinder body 4.

The compression block 6 includes a limit block located outside the cylinder body 4 and a movable rod capable of moving inside the cylinder body 4 .

The utility model has two inflation methods. One is that when the tire pressure is insufficient, the external protruding 1 at the compression block 6 installed on the rim 3 will deform when it contacts the ground, thereby pushing the piston to move upward. When the tire continues to Forward, the compression block 6 leaves the ground, and the spring 5 on the air cylinder body 4 will reset the piston, and go back and forth in turn, thereby constantly inflating the tire to keep the wheel at a certain air pressure; The power supply of the air pump 7 is connected to the power supply interface 8 of the air pump 7 to supply power for the air pump 7 to drive the air pump 7 to move, and the air pump 7 quickly inflates the wheels through the inflation check valve.

The above-mentioned embodiments are preferred implementation modes of the present utility model, which are only used to facilitate the description of the present utility model, and are not intended to limit the present utility model in any form. Anyone with ordinary knowledge in the technical field, if they do not depart from this utility model Within the scope of the technical features mentioned in the utility model, the equivalent embodiments that make partial changes or modifications made by using the technical content disclosed in the utility model, and do not deviate from the technical features of the utility model, still belong to the technical features of the utility model In the range.
