Description

  The present invention relates to a structure of a power toy car tire, and more particularly, a tire structure that firmly adsorbs to the ground, has a tensile strength, and improves the stability and power efficiency of the tire at the moment of starting.

The tires of general toy cars are mainly divided into a hard tire body made of a plastic material and a soft tire body made of a rubber material. The hard tire is hard to be deformed, but has a small frictional force and is slippery. Therefore, the hard tire is used for a power toy car of no power level or a beginner level. The rubber-made soft tires are generally used in middle-class or higher powered toy cars because they have a buffering effect that firmly adheres to the ground and avoids the best vibration. Conventional power toy cars mainly use an engine or a motor as a power source, and have a fast acceleration power at the start. As shown in FIG. 1 and FIG. 2, when the tire of the prior art covers the ring body 20 with the tire body 10 and starts to accelerate, the rotational speed of the tire is faster than the speed of a general automobile. Since the tire body 10 is made of soft rubber, the effect of tensile strength is poor, and the tire body 10 is pulled into an elliptical shape as shown in FIG. When the tire body 10 is observed from the side surface, the width of the tire body 10 is narrowly deformed as shown in FIG. 2, so that the outer peripheral pattern of the tire body 10 is deformed. Therefore, not only the power of the vehicle is greatly affected, but also the vehicle is easily overturned due to deformation and slip, and the stability and efficacy at the start of the power toy vehicle are poor.

  In view of the prior art, the present invention is a power toy vehicle that provides a tire structure that is resistant to deformation and has a tensile strength that firmly adsorbs to the ground, improves the stability of the toy car at the moment of startup, and increases its power efficiency The main problem is to provide a tire structure.

In order to solve the above problems, the tire structure of the present invention is made of a rubber material, and a tensile net is provided inside the tire body. The present invention specifically realizes the above objects and effects by the following technical means:
A tensile net in the tire body is installed near the inner wall.
The tensile net inside the tire body is installed on the wall adjacent to the outer edge of the pattern.
The tensile net is sandwiched in the center of the tire body.
The tire main body has one or more tensile strength nets.
The tensile strength net is knitted with a tensile strength material such as a nonwoven fabric or a wire.
By applying an adhesive layer to the surface of the tensile strength net, the bonding strength with the tire body is increased.

  The present invention provides a tensile net that increases the tension of the tire body and does not deform even when traveling at high speeds. It solves the problem of the car overturning due to tire deformation and increases the power effect of the tire. In addition, the stability of starting and marching a powered toy car is enhanced, and at the same time, the above-described technology adds value to the product, increasing competitiveness and economic profit.

  In order to make the specification of the present invention easier to read, the following description is a description of the configuration, characteristics and other purposes of the power toy car tire, but this does not limit the protection scope of the present invention. Absent. If the same effects are produced, such as various changes and modifications based on the concept of the present invention, application, and changes in shape, all are within the scope of the present invention.

  As shown in FIG. 3, the tire structure is constituted by a tire body 50 on the outer edge that fits with a ring portion (not shown). The tire body 50 is made by injecting a rubber material into a mold and solidifying the tire body 50. The tire body 50 has a good frictional force and increases the force of adsorbing to the ground.

  3 and 4 show that when producing the tire body 50, at least one tensile network 60 is installed inside the mold of the tire body 50, and the tensile network 60 is made of carbon fiber, fiber material, non-woven fabric. It is knitted with a tensile strength material such as a wire. In the first embodiment of the present invention, a single layer of tensile strength mesh 60 is installed corresponding to the inner wall of the tire body 50, and an adhesive layer 65 is applied to the surface of the strength mesh body 60, so that the tire body 50 and Increase joint strength. The melted rubber material is poured into a mold so that the rubber material completely covers the tensile net 60. After the rubber is cooled, a tire body 50 having a predetermined shape is formed, and a tensile net 60 is provided inside the tire body 50. The tensile strength mesh body 60 is completely adhered to the tire body 50 by the adhesive layer 65 applied in advance, thereby firmly adhering to the ground and constituting a structure of a power toy car tire having a tensile strength effect.

  The effects and practical values that occur when the present invention is actually used are as shown in FIGS. At least one layer of tensile strength net 60 is installed inside the tire body 50 of the present invention. The soft tire body 50 can obtain the best tensile strength effect. Since the tire body 50 is made of a rubber material, the frictional force against the ground is not reduced by the pattern, and the tire body 50 is firmly adsorbed to the ground. When the tire accelerates at the moment when the powered toy car starts up or marches at high speed, the tire uses the tensile strength of the tensile strength net 60 to effectively prevent the tire body 50 from being deformed. Whether viewed from the front or the side of FIG. 5, the tire body 50 can maintain a normal state, avoiding the phenomenon of jumping or overturning the car, and stabilizing the start-up march of the power toy car And power efficiency are improved. Furthermore, the soft characteristics of the tire body 50 maintain the effect of buffering and shaking.

  In the second embodiment of the present invention, as shown in FIG. 7, the tensile strength mesh body 60 of the tire of the present invention is installed at the center of the tire body 50. In the third embodiment of the present invention, as shown in FIG. 8, the tensile strength net 60 of the tire body 50 is installed at a position adjacent to the outer edge of the pattern. Each of the above-described embodiments has the same merit and practical value as the first embodiment.
