Description

Pneumatic Tire {A PNEUMATIC TIRE WITH INDICATOR GROOVE}

The present invention relates to a pneumatic tire, and more particularly, to a pneumatic tire for easily managing a tire on which an RFID is installed.

As the industry gradually becomes digital, keywords such as the 4th industrial revolution, digitalization, and EV are also an issue in the tire industry. One of the most visible movements among them is the RFID (Radio Frequency Identification) tire. RFID can be easily accessed around the world without difficulty. Examples include the nearest transportation card to company employee ID. There is an active movement to apply the RFID function to tires.

The first is due to tire history management. From the tire maker's point of view, many methods are mobilized to know the history of tires when tires are sold and accidents occur. First, it is necessary to collect and analyze all information, such as production history from the date of manufacture, information on where it was used, and sales history. However, the current barcode system cannot contain such a lot of information, so it takes a lot of work. Also, in most cases, barcodes are damaged while driving.

The second is the requirements of automobile manufacturers. Automakers are also pushing for the electronicization of all production lines due to the digitalization of the industry. For such electricization, all parts that make up a car must be electronically made, and tires are no exception. However, in the case of tires, barcode information is limited, and there are concerns about damage and inconvenience of reading information. In addition, RFID attachment of tires is visualized for many reasons, and many patents are pouring out from the attachment location to the method.

However, in the case of current RFID tires, there is only a mark indicating that RFID is attached, and the part where it is attached is not specified. The reason is that it is not easy to indicate the location where the RFID is inserted.

Hereinafter, the related prior literature will be reviewed. Identifiers in the following prior art are irrelevant to the present invention.

Korean Patent Laid-Open No. 10-2020-0103974 'RFID tag for tires' relates to an RFID tag for tires, which may cause tire stretching action that may occur after the manufacturing process and shipment, and damage to the antenna pattern and the RFID chip from the external environment. This is to prevent deterioration of the antenna performance and at the same time prevent the deterioration of the antenna performance.

In the present specification, terms such as “comprise” or “have” are intended to designate that a feature, number, step, operation, component, part, or combination thereof described in the specification exists, but one or more other features It is to be understood that this does not preclude the possibility of the presence or addition of numbers, steps, operations, components, parts, or combinations thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is to facilitate RFID reading by providing small grooves at regular intervals on the circumference of a sidewall mold of an RFID tire to indicate the RFID insertion position inside the groove. Figure 1 shows the pneumatic tire of the present invention. The present invention is a pneumatic tire including a tread part 100, a sidewall part 200, and a bead part 300, as shown in Fig. 1. In the sidewall part 200, a plurality of Provided is a pneumatic tire in which RFID (Radio Frequency Identification) is inserted and installed in the circumferential direction, and an indicator groove 400 is formed on the surface of the sidewall part 200 at the position of the RFID installed.

The indicator grooves 400 are installed at equal intervals along the circumferential direction of the tire, and it is preferable that there are 12 to 20 indicator grooves. In addition, it is preferable that the indicator grooves 400 are equally installed on both the left and right sides of the tire. This can be expected to have the effect of making the identification easier by allowing the mark to be seen even when the direction of the tire is changed.

Accordingly, it is possible to know the location where the RFID is attached through the indicator groove 400 of the present invention, so that information on the tire can be quickly read in the process from production to distribution. However, if it cannot be read, the destruction of the RFID can also be predicted. In the absence of such an indicator, it is difficult to determine the exact location, so it takes a lot of time to identify the RFID, and time can be wasted by recognizing a problem that cannot be read due to the damage of the RFID because the location cannot be accurately found.

That is, the indicator groove of the present invention becomes an important guide to know the position of the RFID and the position of the joint between each semi-finished product of the green tire that has been molded.

Figure 2 is a perspective view of the pneumatic tire of the present invention. The position of the indicator groove 400 is basically located in the thickest portion of the sidewall portion 200 and is located in the sidewall protector 210 if necessary. The sidewall protector is usually used for city buses among truck and bus radial tires (TBR tires). Due to the nature of the operation, which requires getting on and off at each stop, the sidewall protector serves to protect the sidewall from abrasion caused by the curb. Design thick as a pillar.

3 is a cross-sectional view of the main part of the indicator groove of the present invention. The indicator grooves of the present invention are formed at regular intervals on the sidewall part 200 side of the tire at regular intervals. It can be determined to the extent that it does not affect However, if the width is wide, the appearance is not good, and if the width is too small, it is difficult to determine the location of the RFID through the tube, so 5 to 7 mm is preferable.

If the depth is too deep, the sidewall gauge becomes thinner and it is difficult to secure the rubber layer of the carcass. If the depth is too low, the marks may disappear due to wear during use. This also applies to the case of wide width. Therefore, a depth of 3 to 5 mm is appropriate.

That is, as shown in FIG. 3 , the depth h of the indicator groove 400 is 3 to 5 mm, and the width w is preferably 5 to 7 mm.

4 is a cross-sectional view of an embodiment in which the interior of the indicator groove of the present invention is painted. In order to improve visibility of the indicator groove 400 , the interior of the indicator groove 400 may be painted. It is preferable that the dye for coloring is fat-soluble.

Alternatively, as shown in FIG. 5 , a colored body 410 may be inserted. The colored body 410 may be colored rubber, synthetic resin, or the like.

3 and 4, the indicator groove 400 is formed on the inserted RFID to indicate the location of the RFID. The present invention further provides a configuration in which, as shown in FIG. 5 , the indicator groove 400 is formed at a position corresponding to the joint portion of each semi-finished product of the tire. Basically, tires are molded by winding various types of rubber sheets on a drum and turning them up. At this time, the largest joint parts are carcass, tread, bead, and belt. Therefore, if these joint parts are concentrated in one place, it becomes a problem of durability, so the positions are distributed at intervals of 90° to 180°. These joint parts are a great help in the epidemiological investigation when quality issues arise in tires, and there are actually many separation accidents in these joint parts. It is very helpful to deal with quality issues if you know these joint parts with a simple mark. Therefore, the indicator groove 400 of the present invention becomes an important guide to know the location of each semi-finished product of the green tire, RFID, which has been molded. That is, since the semi-finished products overlap each other in order to form the inner structure of the tire during manufacturing of the green tire, cracks may grow in the joint portion or quality problems such as reduced uniformity may occur. Accordingly, by allowing the indicator groove 400 of the present invention to identify the position of the joint portion, it is possible to efficiently respond to such quality problems or cracks.

As shown in FIG. 5 , the indicator groove 400 may be positioned to correspond to the joint part, but it maintains a certain angle with the joint part when the RFID is attached, and the indicator groove 400 corresponds to the position of the RFID. can be installed as much as possible. In this case, both the RFID and the joint position can be confirmed through the indicator groove 400 .

The foregoing description of the present invention is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and likewise components described as distributed may also be implemented in a combined form.
