[Prior Art] A general explosion-proof tire is to add a sub-tire in a tire. When the car is in a puncture, the tire and the rim can be separated by the sub-tire to prevent the rim from contacting the ground. Deformation can prevent the car from losing balance due to a puncture, causing an accident of rollover. As shown in Figure 1, the new patent case of Taiwan Bulletin No. M291376, "Structure of Automobile Explosion-Proof Tire", is provided with a pneumatic tire 12 on the periphery of a wheel rim, and an additional tire 12 is added between the pneumatic tire 12 and the rim u. There is a sub-tire 13 having a solid cross section, and a retaining seat 14 is disposed on the periphery of the rim 11. The sub-tire 13 is fixed on the limiting seat 14, and when the pneumatic tire 12 bursts, the air is deflated. By using the sub-tire 3 to support between the ground and the rim 11, the rim u can be prevented from directly contacting the ground during the puncture, and the sub-tire 13 is positioned by the limiting seat 14 without An offset is created, thus preventing the car from losing balance or getting out of control. During the assembly process, before the pneumatic tire 12 is sleeved on the rim u, the β haizi tire 13 must be installed on the limit seat 丨 4 to position the sub-tire 3 in the pneumatic tire 12, however, The sub-tire 13 is made of an elastic material, and it is not easy to plug and fix the sub-tire 13 to the stopper seat 14, which increases the difficulty in assembly. In addition, since the sub-tire 13 is fixed to the limit seat 14 and is spaced apart from the pneumatic tire 12, the pneumatic tire 〖2 is only the thickness of the general tire 201121813 specification, although the tire can be used by the tire tire. The cushioning of 13 prevents the car from getting out of control, but the pneumatic tire 12 is subjected to sharp object puncture without an adjustment thickness and has a risk of puncture. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide an explosion-proof tire which is simple in structure and can prevent runaway from being blown out.于疋' The explosion-proof tire of the present invention is for arranging the outer edge of a rim, the explosion-proof tire comprises a main carcass, a second sidewall, a thickened body, and a pair of the main carcass is made of an elastic material. Made, the main carcass defines a vertical tangent at the center of the section, and the outer edge of the main tire is in contact with the ground. The sidewalls are made of an elastic material which is annular and which are connected to both sides of the main carcass, wherein an air chamber is defined between the sidewalls and the main carcass. "Hai thickening is made of elastic material, extending from the inner edge of the main tire and between the two sidewalls. The secondary carcass is made of an elastic material, formed on the thickened body, and extends along the vertical tangential line and extends in the air chamber, the secondary carcass having one side of the rim and being curved Contact surface. The utility model has the advantages that when the tire is blown, the auxiliary carcass is extended into the air chamber, so that the auxiliary carcass can be spaced between the rim and the ground, and the rim can be prevented from contacting the ground and deformed. The contact surface of the secondary carcass is curved. The contact surface of the secondary carcass can immediately abut the rim under the puncture, thereby reducing the offset of the vertical tangential line of the main carcass. 201121813 Tire-free offset 'x' by thickening the body attached to the inner edge of the main tire can increase the overall thickness of the tire, reducing the risk of being pierced by the sharp object, thus reducing the chance of puncture. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. As shown in FIG. 2, in a first preferred embodiment of the explosion-proof tire of the present invention, the explosion-proof tire comprises a main carcass 3, a second sidewall 4, a thickened body 9, and a pair of carcass 5, the explosion-proof tire of the present invention. It can be applied to a traveling vehicle of an airplane, a truck, a car, a locomotive or a bicycle, and this embodiment takes a car as an example. As shown in FIGS. 2 and 4, the main carcass 3 is made of an elastic material of rubber and is sleeved on the outer edge of a rim 2, and the main carcass 3 defines a vertical tangent L1 at the center of the section. And two intersecting lines L2 respectively intersecting the vertical tangent u, and the outer edge of the main carcass 3 can be in contact with the ground (not shown), as shown in FIG. 2, and the sidewalls 4 are also made of rubber elastic material. The special tire wall 4 is formed in a ring shape and is respectively connected to both sides of the main carcass 3, wherein a gas chamber 6 is defined between the tire wall 4 and the main carcass 3. The thickened body 9 is also made of an elastic material of rubber and extends from the inner edge of the main carcass 3 and between the two sidewalls 4. As shown in Figures 2 and 4, the secondary carcass 5 is also a large torus made of rubber elastic material 201121813, which has a solid section and is formed on the thickened body 9 and is perpendicular to the tangent. L1 extends to extend in the plenum 6, the secondary carcass 5 having an arc-shaped contact surface 51 facing the rim 2, since the plenum 6 not only has the secondary carcass 5 extended, but Filled with air pressure gas, the impact of the explosion-proof tire of the present invention has the effect of elasticity and suspension, does not affect the original characteristics of the tire. According to the above structure, when the car is traveling, if the tire is puncture by a sharp object, the tire is puncture, As shown in FIG. 3, the air pressure gas in the air chamber 6 will be tapered (4), which will cause the rim 2 to gradually approach the ground and there is a risk of wear and deformation of the waste. However, the air chamber 6 is disposed in the air chamber 6. The sub-fourth (5) 5 is offset to the rim 2, so that the rim 2 is spaced from the ground, and the rim 2 can be prevented from being directly rubbed against the ground and compressed and deformed. At the same time, in the case of a puncture, the field 5 can still be driven by the rim 2, providing temporary driving ability, so that the car can slow down to the shoulder or the next communication Ask for help, while avoiding the risk of suffering from the rear of the vehicle rear-ended. It should be noted that each part of the main carcass 3 may be puncture by a sharp object to cause a puncture, so that the sub-carcass 5 is mainly rim 2 along the vertical tangent L1 as shown in FIG. Movement (ie, the imaginary line moves to the solid line), it is also possible to move obliquely along the intersecting line L2 to the rim 2, and the contact surface 51 of the secondary carcass 5 is in a regular manner to make the secondary tire The contact surface 51 of the body 5 can instantly contact the rim 2, thereby reducing the offset of the vertical tangent li of the main carcass 3 to avoid offset of the tire. With the above design, the explosion-proof tire of the present invention can achieve the following benefits: 201121813 1. The opportunity to reduce the puncture can be the thickness of the overall abortion by the thickening body 9 attached to the inner edge of the main carcass 3, Thereby reducing the risk of being pierced by the sharp object, thus

For example, the second preferred embodiment of the explosion-proof tire of the present invention is substantially the same as the first preferred embodiment, except that the tire of the present embodiment can be applied to a traveling load with a large load. The aircraft has a plurality of layers of canvas 7 and a wire 8 ′ which are spaced apart from the sidewall 4, the main carcass 3, and the secondary carcass 5, The steel wire 8 is extended in the tire wall 4 and the main carcass 3'. In this embodiment, not only can the main carcass 3 be offset when the tire is blown, but the number of the canvas 7 can be utilized to (4) the tire. The pressure that can be withstood 'reduces the force of the tire to be deformed' to increase the load carrying capacity of the tire carrying the traveling vehicle' and the steel wire 8 is used to strengthen the tension and strength of the sidewalls 4 and the main tires. In summary, the auxiliary carcass 5 is placed in the air chamber 6 so that the auxiliary carcass 5 can be spaced between the rim 2 and the ground, thereby preventing the rim 2 from directly contacting the ground during a puncture. Deformation is generated. Further, since the contact surface 51 of the auxiliary carcass 5 is in an arc shape, the contact surface 51 of the secondary carcass can immediately reach the rim 2, thereby reducing the main carcass. The offset of the vertical tangent L1 of '3' avoids the offset of the tire and, in turn, by the connection in the main month. The thickened body 9' at the inner edge of the body 3 can increase the thickness of the entire tire to reduce the risk of being pierced by the sharp object, thereby reducing the chance of puncture, and thus the object of the present invention can be achieved. However, the above is only two preferred embodiments of the present invention, and 201121813 is not intended to limit the implementation of the present invention, that is, simple equivalent changes made according to the scope of the present invention and the description of the invention. And modifications are still within the scope of the invention.
