To achieve the purpose described above, the present invention provides the tire having an electronic device in consideration of a carcass arrangement interval, the tire including: a carcass unit having a plurality of carcass codes; and an electronic device having an antenna extending in a longitudinal direction and provided on a side wall, wherein the electronic device is provided such that, when the antenna forming a closed loop is defined as an antenna unit, the antenna unit is arranged between the arranged carcass codes not to overlap each other.

Description

Tires equipped with electronic devices that take into account the carcass arrangement spacing and angle

[0001] The present invention relates to a tire equipped with an electronic device taking into account the carcass arrangement spacing, and more specifically, to a tire equipped with an electronic device taking into account the carcass arrangement spacing and angle to increase induced electromotive force to improve recognition performance, enhance durability of the electronic device, and minimize impact on the inside of the tire.

[0002]

[0003] With the recent increase in technological developments such as connected cars and autonomous vehicles, RFID tires, electronic tires, and intelligent tires with electronic devices attached or embedded in the tires are being developed and sold.

[0004] These intelligent tires are designed to measure tire-related information, process the measured information, and transmit the information to the user.

[0005] And, various wireless transmission methods are being used to transmit this information.

[0006] In particular, the electronic devices installed in intelligent tires are designed with electronic chips and antennas according to the frequency and recognition distance desired by each consumer, and can acquire information transmitted at various frequencies depending on the circuit design of the receiving end.

[0007] Normally, the transmission frequency takes into account the permittivity of air, but since the permittivity of air is practically 1, it is usually designed so that there is no difference between the transmission frequency and the reception frequency.

[0008] However, depending on the installation location of the electronic device, the compound, tire structure, sidewall thickness, and air layer conditions will vary, and the permittivity will also vary depending on the change in these conditions.

[0009] Although this change in permittivity modulates the transmission frequency, causing a problem of reduced information accuracy, there was a problem in the past of designing the transmission frequency to be the same as the standard reception frequency.

[0010] In addition, in the past, when inserting electronic devices into tires, directionality was not taken into consideration, so there was a problem that the electronic devices were easily damaged when the bead wire was repeatedly bent in the direction of the tread.

[0011] Moreover, there was a problem in the past where the induction power was reduced as the carcass code and antenna overlapped, which deteriorated the recognition performance of the electronic device.

The singular expression includes the plural expression unless the context clearly indicates otherwise. In this specification, it should be understood that the terms "comprises" or "has" indicate the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0064] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0065] FIG. 1 is an exemplary diagram of a tire equipped with an electronic device, taking into account the carcass arrangement spacing and angle according to one embodiment of the present invention.

[0066] Referring to FIGS. 1 and 2, the tire (100) may be provided to have a first point (110) where the bead wire and the bead wire rubber meet, a second point (120) which is the end of the bead filler, and a third point (130) which is the end of the carcass and the belt.

[0067] In addition, the tire (100) may be provided to further include an electronic device (140), a receiving device (150), and a carcass (160).

[0068] Here, the electronic device (140) may be arranged to be positioned on the side wall between the first point (110) and the third point (130).

[0069] Figure 2 is a numerical analysis graph showing shear stress according to location according to one embodiment of the present invention.

[0070] Referring to FIG. 2, the electronic device (140) may be positioned between the first point (110) and the third point (130), and may be provided at a position corresponding to a position where the shear stress is least applied.

[0071] In particular, looking at the graph of Fig. 2, it can be seen that the shear stress is large at locations adjacent to the first point (110) and the third point (130). Accordingly, the electronic device (140) may be arranged to be inserted and attached at a location spaced at least 11 mm apart from the first point (110) and the third point (130), where the shear stress is relatively small.

[0072] The above electronic device (140) can be configured to be integrated with the tire by applying the topping material to only one side and integrating it during the molding process and curing it.

[0073] Figure 3 is an exemplary diagram of an electronic device according to a first embodiment of the present invention.

[0074] Referring to FIG. 3, the electronic device (140) according to the first embodiment may include a base (141), a main chip (142), an antenna (143), and a memory.

[0075] The above base (141) is provided to form the body of the electronic device (140), and the main chip (142), antenna (143), and memory can be provided on the base (141).

[0076] The above main chip (142) is provided on the base (141) and can be equipped with an electronic module including an electronic circuit.

[0077] The above antenna (143) may be provided on the base (141) and may be directly or indirectly connected to the main chip (142).

[0078] Specifically, as illustrated in FIG. 3, the antenna (143) may be characterized by being formed to extend and be exposed on both sides from the base.

[0079] And, the antenna (143) can be provided in a spring shape.

[0080] The antenna (143) according to the first embodiment of this spring type is formed to be composed of antenna units that form a closed loop in a certain pattern, and the pitch (P) at this time may mean the interval between repeating antennas.

[0081] Figure 4 is an exemplary diagram of an electronic device according to a second embodiment of the present invention.

[0082] As illustrated in FIG. 4, the electronic device (240) may be provided in the form of a base (241), a main chip (242) provided on the base (241), and an antenna (243) printed on the base (241).

[0083] At this time, the antenna (243) on the base (241) may be made of a thin film or the like.

[0084] In this way, the antenna (143, 243) may be provided in an exposed form, or may be provided in a soldered or chip-wrapping form. The antenna (143, 243) may also be configured independently from the main chip (142).

[0085] The antenna (243) according to the second embodiment of this two-dimensional film type is formed as an antenna unit composed of a closed loop formed in a certain pattern based on the center line (C), and the pitch (P) at this time may mean the spacing between the antennas. Specifically, the pitch (P) of the antenna (243) according to the second embodiment may be defined as the spacing between screw threads.

[0086] Figure 5 is an exemplary diagram of an electronic device according to a third embodiment of the present invention.

[0087] Referring to FIG. 5, the electronic device (340) may be provided in the form of a base (341), a main chip (342) provided on the base (341), and an antenna (343) printed on the base (341).

[0088] The base (341) may be formed of a dielectric. The dielectric may be formed of FR-4 PCB or FPCB. FR-4 PCB or FPCB has a high dielectric constant compared to air. In addition, the base (341) may be formed in a band shape whose length is longer than its width. In this case, the base (341) is formed with a minimum width, thickness, and length that does not damage the rubber of the tire.

[0089] The main chip (342) may be arranged to be mounted on the center of the upper surface of the base (341). The main chip (342) may be mounted on the side base (341) in a flip chip form. When the main chip (342) is mounted on the side base (341) in a flip chip form, wire bonding is omitted, eliminating the need for soldering, thereby simplifying the manufacturing process. In addition, the connection portion of the main chip (342) and the antenna (343) may be connected with a conductor pattern, thereby increasing the connection reliability of the connection portion of the main chip (342) and the antenna (343).

[0090] The above antenna (343) can be manufactured as an antenna with a three-dimensional pattern of left-right symmetry to secure the maximum antenna length on a limited base (341).

[0091] The above antenna (343) may include an upper pattern (344), a lower pattern (345), and a via hole (346).

[0092] The upper pattern (344) is formed on the upper surface of the base (341), and the lower pattern (345) is formed on the lower surface of the base (341). The via hole (346) is formed penetrating the base (341), and may be provided to connect a plurality of upper patterns (344) and a plurality of lower patterns (345) to form a pattern inside the base (341).

[0093] The upper pattern (344) and the lower pattern (345) can be formed by attaching copper foil to the upper and lower surfaces of the base (341) and etching them, or by forming a seed layer and a plating layer on the upper and lower surfaces of the base (341) and then etching them.

[0094] A plating layer may be further formed in the via hole (346) connecting the upper pattern (344) and the lower pattern (345).

[0095] The antenna (343) according to the third embodiment of this plate type is formed as an antenna unit made of a closed loop with a certain pattern, and the pitch (P) at this time may mean the interval of the antenna including one each of the upper pattern (344) and the lower pattern (345).

[0096] Again, referring to FIG. 3, the antenna (143) can be arranged at equal or unequal intervals at intervals of 0.1 to 10 mm, and can be made of a material such as a single metal, an alloy, a polymer containing CNT, or a printed material.

[0097] Additionally, the antenna (143) may be provided to be coated with a conductive or non-conductive material.

[0098] The above memory is provided to store tire information such as manufacturer, item information, and serial barcode, and can be provided with one or more in a size of 96 bits or more.

[0099] Additionally, the electronic device (140) may be designed to have a transmission frequency that is 1.05 times greater than the standard reception frequency for measuring tire information.

[0100] More specifically, it can be arranged to derive the dielectric constant from the attachment location of the electronic device (140) to the receiving device (150).

[0101] At this time, the measurement position of the dielectric constant is the dielectric constant at the position where the straight line intersects the tire, excluding air, when the installation positions of the electronic device (140) and the receiving device (150) are drawn in a straight line. In addition, the receiving device (150) may be positioned at a distance of 1 mm to 1,500 mm from the surface of the tire sidewall.

[0102] And, the factors affecting this dielectric constant may include one or more rubbers, one or more carcasses and other semi-finished products such as polymers for the composition of the tire.

[0103] That is, it can be arranged to measure and derive the dielectric constant affected by obstacles located between the electronic device (140) and the receiving device (150).

[0104] Next, the electronic device (140) may be designed to transmit a value obtained by multiplying the reception frequency measured by the receiving device (150) by the square root of the derived permittivity.

[0105] In addition, the receiving device (150) may be further provided to select information by determining whether the receiving frequency falls within a preset error range from the target receiving frequency.

[0106] Specifically, the receiving device (150) may be arranged to first compare, when a frequency is received, whether the received reception frequency falls within a preset error range with the target reception frequency.

[0107] In addition, when the reception frequency is outside the target reception frequency and the preset error range, the information received when the reception frequency is outside the target reception frequency and the preset error range may be arranged to be discarded without being used.

[0108] That is, the receiving device (150) may be arranged to obtain only information corresponding to a reception frequency within a preset error range, and then analyze the information to provide the user with necessary information.

[0109] The present invention, thus prepared, can further improve the reliability of information provided to users because it can minimize the possibility of information being modulated according to frequency.

[0110] FIG. 6 is an exemplary diagram showing the angle between the center line of the carcass portion of a tire equipped with an electronic device and the electronic device, taking into account the carcass arrangement interval according to one embodiment of the present invention.

[0111] Referring to Fig. 6, the carcass portion (160) may be provided with a plurality of carcass codes (161). In addition, the carcass codes (161) may be arranged to form a 90-degree angle with respect to the driving direction.

[0112] In addition, the electronic device (140) may be arranged so that the center line (C) connecting the centers of both ends of the antenna (143) and the carcass code (161) form an angle of 70 to 110 degrees.

[0113] More preferably, the electronic device (140) may be arranged so that the center line (C) connecting the centers of both ends of the antenna (143) and the carcass code (161) form an angle of 80 to 105 degrees.

[0114] FIG. 7 is an exemplary diagram showing a case where the angle between the center line of an electronic device and the carcass code is 90 degrees according to an embodiment of the present invention, and FIG. 8 is an exemplary diagram showing a case where the angle between the center line of the electronic device and the carcass code is 0 degrees.

[0115] Referring further to FIGS. 7 and 8, when the electronic device (140) forms a 90-degree angle with the carcass code (161) as in FIG. 7, the direction of the stress generated by the flexural movement from the bead wire of the tire (100) to the tread direction and the direction of the electronic device (140) are parallel, so the durability of the electronic device (140) is less deteriorated.

[0116] Specifically, as a result of the bending test, the electronic device (140) was able to stably measure signals even after 5 million cycles.

[0117] However, when the electronic device (140) forms a 0 degree angle with the carcass code (161) as shown in FIG. 8, the direction of the stress generated by the flexural movement from the bead wire of the tire (100) to the tread direction and the direction of the electronic device (140) are perpendicular, so the durability of the electronic device (140) is clearly reduced.

[0118] Specifically, the bending test results showed that the signal could be measured reliably only up to 25 times.

[0119] Accordingly, it is preferable that the electronic device (140) be arranged so that the center line (C) connecting the centers of both ends of the antenna (143) and the carcass code (161) form an angle of 70 to 110 degrees or 80 to 105 degrees, so as to minimize damage caused by the flexural movement of the tire (100).

[0120] In addition, the electronic device (140) may be characterized in that the width and thickness are formed to be greater than 0 and less than 3 mm, and the total length is formed to be 30 mm to 100 mm. The reason for this arrangement is that the thinner and shorter the thickness of the wireless electronic device (140), the less deformation occurs due to the flexural movement of the tire (100), and thus the less the durability is reduced. On the other hand, if the length of the electronic device (140) is excessively short or thin, there is a problem that the durability is reduced even with a small impact. Therefore, the electronic device (140) is not limited in shape, but it is preferable to be formed within the above range.

[0121] FIG. 9 is an exemplary diagram showing the arrangement of an electronic device and a carcass according to one embodiment of the present invention.

[0122] The above electronic device (140) can be arranged so that the antenna (143) and the carcass code (161) do not overlap.

[0123] More specifically, when the electronic device (140) defines the antenna (143) forming a closed loop as one antenna unit as described with reference to FIGS. 3 to 5, it can be arranged so that the antenna units do not overlap between the arranged carcass codes (161).

[0124] Specifically, the spacing between the carcass codes (161) and the spacing between the antenna units may be set differently.

[0125] For example, the electronic device (140) may be arranged so that at least one antenna (143) is positioned between a pair of adjacent carcass codes (161) at a pitch interval. To this end, the pitch (P) length of the antenna (143) may be adjusted.

[0126] Fig. 10 is an exemplary diagram showing the arrangement of an electronic device and a carcass according to another embodiment of the present invention.

[0127] Alternatively, as shown in Fig. 10, the electronic device (140) may be arranged so that at least one carcass code (161) is arranged within the pitch, which is the interval of the antenna (143). To this end, the pitch (P) length of the antenna (143) may be adjusted.

[0128] Specifically, the pitch, which is the spacing of the antennas (143), is usually 0.01 mm to 2.00 mm and is arranged at equal or unequal intervals.

[0129] Figure 11 is an exemplary diagram showing an electromagnetic field according to one embodiment of the present invention.

[0130] And, as shown in Fig. 11, the antenna (143) is connected to the main chip (142) of the electronic device (140) that operates wirelessly, and an electromagnetic field supplied from an external dedicated tool is linked to the antenna to generate an induced current. Therefore, the pitch interval and number of turns of the antenna (143) are very important.

[0131] A large number of the above pitches per unit length can generate a large amount of induced current or voltage. An external electromagnetic field is transmitted through the rubber and carcass cord (161) of the tire (100). The larger the magnetic field, and the thinner and more monolithic the tire (100) structure, the greater the induced current or voltage supplied to the wireless electronic module.

[0132] The above carcass code (161) is usually defined as EPI, but when converted to a numerical value, it is arranged at intervals of 0.2 to 0.3 mm.

[0133] The induced electromotive force (V) can be calculated as the product of the change in magnetic flux (Φ) per unit time and the number of turns (N).

[0134] Therefore, in order to increase the voltage induced in the antenna (143) embedded inside the tire, the magnetic field supplied from the outside must be increased or the number of windings must be increased.

[0135] Externally supplied magnetic fields are difficult to vary when using tools, so they are calculated as fixed constants. While the amount of variation can be calculated by supplying an AC waveform, the magnitude is calculated as a constant that does not change. Furthermore, there is a limit to how long the antennas of wireless electronic devices can be extended indefinitely.

[0136] Therefore, the most preferable method is to arrange the carcass code (161) and the antenna (143) so that they do not overlap to increase the induced electromotive force.

[0137] Accordingly, the present invention proposes a method in which at least one antenna (143) pitch of the electronic device (140) is arranged between the carcass codes (161) or at least one carcass code (161) is arranged in a cross pattern between the antenna (143) pitches, thereby maximizing the induced electromotive force thereof.

[0138] In addition, in order to increase this induced electromotive force, as described above, it is preferable that the longitudinal direction of the electronic device (140) be arranged at an interval of 70 to 110 degrees from the carcass code (161).

[0139] And, since guide lines are arranged at regular intervals on the semi-finished surface of the carcass (160), the starting point of the center line (C) of the electronic device (140) can be arranged to be aligned with this line.

[0140] In this arrangement, a structure can be secured in which at least one antenna (143) pitch is arranged between two of the carcass codes (161) or at least one carcass code (161) is arranged between one of the antenna (143) pitches.

[0141] The present invention, thus prepared, can be manufactured so that the electronic device (140) is integrated into the tire (100).

[0142] In addition, according to the present invention, the problem of the electronic device (140) being damaged due to a decrease in durability caused by the flexing and stretching of the tire can be minimized.

[0143] And, according to the present invention, the recognition performance of the wireless electronic device (140) can be improved even at a longer distance by increasing the induced electromotive force.

[0144] In addition, the present invention can provide an optimal recognition distance because it designs the transmission frequency of the electronic device by reflecting the permittivity according to the location where information is to be read, the structure of the tire, the material, etc.

[0145] Although the description of the present invention has been illustrated with limited drawings, it is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical spirit or essential characteristics of the present invention. 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 component may be implemented in a distributed manner, and likewise, components described as distributed may be implemented in a combined form. Furthermore, the described techniques may be performed in a different order than the described method.
