Description

The present invention relates to a non-contact data transmitter / receiver.

As a non-contact data receiver / transmitter capable of receiving information from the outside using electromagnetic waves or radio waves as a medium and transmitting the information to the outside, such as an information recording medium for RFID (Radio Frequency Identification), for example. , IC tag can be mentioned. The IC tag includes, for example, an inlet composed of a base material, an antenna provided on one surface thereof and connected to each other, and an IC chip.
When the IC tag receives an electromagnetic wave or a radio wave from an information writing / reading device, an electromotive force is generated in the antenna due to a resonance action, and this electromotive force activates the IC chip in the IC tag to display the information in the IC chip. It is converted into a signal, and this signal is transmitted from the antenna of the IC tag.

IC tags are often used for the preservation and management of automobiles on a vast site where a large number of automobiles gather. In this case, since the IC tag is used outdoors for a long period of time while being installed on the ground, high waterproofness and high durability against bending, impact, etc. are required. In particular, the IC tag for this purpose is required to have impact resistance (durability) to the extent that it will not be damaged even if it is stepped on by an automobile.

Conventionally, IC tags used for storage management of automobiles include, for example, an inlet composed of a film-like base material, an antenna provided on one surface thereof and an IC chip connected to each other, and the entire inlet thereof. Is being studied (see, for example, Patent Document 1).

It has a sloping shape (hill shape). In addition, in FIG. 6, a dent is formed in the central portion 46, but assuming that there is no dent, the first covering member 40 has the above-mentioned shape.

As shown in FIGS. 1, 4, 5 and 8, the first covering member 40 has an antenna on the upper surface 40a between the central covering portion 40A and the antenna covering portion 40B in the thickness direction of the antenna covering portion 40B. A groove 47 recessed from the covering portion 40B is formed.

As shown in FIGS. 1 and 8, in the first covering member 40, the outer edge of the central covering portion 40A, that is, the outer edges of the first connecting portion 44 and the second connecting portion 45 is in the thickness direction of the first covering member 40. On the other hand, it is formed diagonally. More specifically, the outer edges of the first connecting portion 44 and the second connecting portion 45 are formed obliquely so as to gradually increase in width as the distance from the central portion thereof increases. That is, in the cross section of the first covering member 40 along the thickness direction, the outer edges of the first connecting portion 44 and the second connecting portion 45 are tapered.

As shown in FIGS. 1 and 8, in the first covering member 40, the outer edge of the antenna covering portion 40B is formed obliquely with respect to the thickness direction of the first covering member 40. More specifically, the outer edge of the antenna covering portion 40B is formed obliquely so that the width gradually increases as the distance from the central portion thereof increases.

As shown in FIG. 6, the second covering member 50 is formed so as to cover the second surface 21c of the hard substrate 21 and the reinforcing plate 70. By joining the peripheral edge portion 50a of the second covering member 50 to the peripheral edge portion 40b of the first covering member 40, the entire inlet 20 is covered by the first covering member 40 and the second covering member 50.

As shown in FIGS. 1 and 6, the reinforcing plate 70 is provided on the second surface 21c (the surface opposite to the first surface 21a) of the hard substrate 21 so as to cover the accommodating recess 41 in a plan view. ..
The plan view shape of the reinforcing plate 70 is not particularly limited, but may be oval, circular, rectangular, or the like.
In FIGS. 1 and 7, the reinforcing plate 70 is oval, and the peripheral edge portion 70a of the reinforcing plate 70 surrounds the peripheral edge portion 41a of the accommodating recess 41.

The reinforcing plate 70 is adhered to the second surface 21c of the hard substrate 21 via an adhesive layer (not shown). As the adhesive constituting the adhesive layer, an epoxy adhesive or the like is used.

The non-woven fabric 60 is arranged in the accommodating recess 41 of the first covering member 40, and is interposed between the accommodating recess 41 and the IC chip 22. The non-woven fabric 60 may cover only the surface of the IC chip 22 opposite to the hard substrate 21 in a state of being arranged in the accommodating recess 41, and the surface of the IC chip 22 opposite to the hard substrate 21 and the surface of the IC chip 22 opposite to the hard substrate 21. It may cover the sides.

Examples of the hard substrate 21 include a composite material substrate such as a glass epoxy resin substrate, a ceramic substrate, and the like.
Examples of the glass epoxy resin substrate include a FR-4 substrate and a CEM-3 substrate. Examples of the FR-4 substrate include R-1705 (flexural modulus 23 GPa) manufactured by Panasonic Corporation. The ceramic substrate is made of, for example, alumina, silicon carbide, or the like.

The flexural modulus of the hard substrate 21 is preferably 9.5 GPa to 470 GPa.
By setting the flexural modulus of the hard substrate 21 to 9.5 GPa or more, durability against bending, impact, etc. can be ensured. Further, by setting the flexural modulus of the hard substrate 21 to 470 GPa or less, a hard substrate 21 having excellent handleability and being inexpensive can be adopted.
For example, when the hard substrate 21 is a glass epoxy resin substrate, the flexural modulus can be set to 9.5 GPa to 36 GPa. When the hard substrate 21 is a ceramic substrate, the flexural modulus can be 74 GPa to 470 GPa.
Depending on the material, the flexural modulus of the hard substrate 21 may be substantially equal to Young's modulus. In that case, the Young's modulus value can be regarded as the flexural modulus.

The IC chip 22 is not particularly limited, and information can be written and read in a non-contact state via the antenna 23, and is a non-contact type IC tag, a non-contact type IC label, or a non-contact type IC card. Anything applicable to RFID media such as the above can be used.
The IC chip 22 can be mounted on the first surface 21a of the hard substrate 21 via solder or the like.

Examples of the material constituting the antenna 23 and the short-circuit portion 24 include a known polymer-type conductive ink, a conductive ink such as a silver ink composition, a metal foil, a metal thin film formed by electroplating or electrostatic plating, and a metal. Examples thereof include metal thin films and metal plates formed by various thin film forming methods such as vapor deposition.

The first coating member 40 and the second coating member 50 are made of a thermoplastic resin, a thermoplastic elastomer, a thermosetting resin, or the like.
A thermoplastic resin is a resin that fluidizes when heated to a glass transition temperature or above the melting point and solidifies when cooled.
Examples of the thermoplastic resin include general-purpose plastics, engineering plastics (engineering plastics), super engineering plastics (super engineering plastics), and the like.
Examples of general-purpose plastics include polyethylene (PE), polypropylene (PP), ABS resin and the like. Examples of engineering plastics include nylon, polycarbonate (PC), polyethylene terephthalate (PET), and the like. Examples of super engineering plastics include polyphenylene sulfide (PPS), polyethersulfone (PES), and polyetheretherketone (PEEK). Examples of the polycarbonate (PC) include Tafflon Neo AG1950 (trade name, flexural modulus 2.1 GPa) manufactured by Idemitsu Kosan Co., Ltd.

The thermoplastic elastomer is a polymer material that exhibits the properties of a rubber elastic body (elastomer) at room temperature, and contains a plastic component (hard segment) and an elastic component (soft segment). The thermoplastic elastomer fluidizes at high temperatures and can be processed.
Thermoplastic elastomers include styrene-based (plastic component is polystyrene (PS), etc.), olefin-based (plastic component is PP, etc.), vinyl chloride-based (plastic component is polyvinyl chloride (PVC), etc.), polyester-based (plastic component). (PET, etc.), polyurethane-based (plastic component is polyurethane (PU), etc.), nylon-based (plastic component is polyamide (PA), etc.) and the like.

A thermosetting resin is a resin that forms a polymer network structure by heat polymerization and is irreversibly cured.
Examples of the thermosetting resin include phenol resin, epoxy resin, melamine resin, urea resin, polyurethane resin, silicon resin and the like.

Among these resins, polycarbonate (PC) is preferable as the resin constituting the first coating member 40 and the second coating member 50 because it is excellent in durability against bending, impact and the like.

The first covering member 40 and the second covering member 50 are formed by injection molding using the above resin.

Examples of the non-woven fabric 60 include non-woven fabrics made of cotton, linen, wool, silk, tencel, rayon, polynosic, cupra, acetate, triacetate, promix, acrylic, polyester, nylon, vinylon, polyurethane and the like.

Examples of the reinforcing plate 70 include a metal plate, a ceramic plate, a fiber reinforced resin plate, a carbon material plate, and the like.
The reinforcing plate 70 is harder than the hard substrate 21. Specifically, the flexural modulus of the reinforcing plate 70 is higher than the flexural modulus of the hard substrate 21.
The flexural modulus of the reinforcing plate 70 can be, for example, 40 GPa to 470 GPa. By setting the flexural modulus of the reinforcing plate 70 to 40 GPa or more, bending deformation of the hard substrate 21 can be reliably suppressed when the second covering member 50 is formed. Further, by setting the flexural modulus of the reinforcing plate 70 to 470 GPa or less, the reinforcing plate 40 which is lightweight and has excellent handleability can be adopted. The flexural modulus of the reinforcing plate 70 may exceed 470 GPa.
Depending on the material of the reinforcing plate 70 (for example, when the reinforcing plate 70 is made of a general metal), the flexural modulus of the reinforcing plate 70 may be substantially equal to the Young's modulus. In that case, the Young's modulus value can be regarded as the flexural modulus.

As the metal plate, a stainless steel plate is suitable. Specific examples of the stainless steel plate include a SUS304 plate (flexural modulus (Young's modulus) 197 GPa, thickness 0.5 mm).
As the metal plate, a carbon steel plate, a duralumin plate, or the like may be used. Specific examples of the carbon steel plate include an S45C plate (flexural modulus (Young's modulus) 205 GPa), and specific examples of the duralumin plate include an A2017P plate (flexural modulus (Young's modulus) 69 GPa).
The ceramic plate is made of, for example, alumina, silicon carbide, or the like.

The thickness of the reinforcing plate 70 is not particularly limited, but may be, for example, 0.1 mm to 1 mm.

According to the non-contact data receiving / transmitting body 10 of the present embodiment, the hard substrate 21 having the central region 21A in which the IC chip 22 is arranged and the antenna forming region 21B extending radially from the central region 21A and the hard substrate 21 are hard. In order to provide the antenna 23 extending to the antenna forming region 21B centering on the IC chip 22 and the covering member 30 covering the IC chip 22, the hard substrate 21 and the antenna 23 on the first surface 21a of the substrate 21. It is possible to provide a non-contact type data receiver / transmitter that is not destroyed even if it is twisted when a vehicle is placed on it. Further, according to the non-contact data receiving / transmitting body 10 of the present embodiment, the antenna 23 extends from the central region 21A to the antenna forming region 21B extending radially in all directions on the first surface 21a of the rigid substrate 21. Therefore, it is possible to provide a non-contact data receiving / transmitting body having a wide communication range and having no directivity and capable of communicating from an arbitrary direction of 360 degrees.

Further, according to the non-contact data receiving / transmitting body 10 of the present embodiment, the rigid substrate 21 is provided on the second surface 21b opposite to the first surface 21a, and is formed on the first covering member 40 in a plan view. A reinforcing plate 70 that is harder than the hard substrate 21 that covers the accommodating recess 41, and a non-woven fabric 60 that is arranged in the accommodating recess 41 and is interposed between the accommodating recess 41 and the IC chip 22. However, it is possible to provide a non-contact data transmitter / receiver that is not damaged. That is, in the non-contact data receiving / transmitting body 10 of the present embodiment, by providing the reinforcing plate 70 for reinforcing the hard substrate 21, when the first covering member 40 and the second covering member 50 are formed by injection molding, the first covering member 40 and the second covering member 50 are formed. When pressure is applied to the non-contact data receiving / transmitting body 10 in the thickness direction, the hard substrate 21 is damaged, and as a result, the connection between the IC chip 22 and the antenna 23 is cut off, or the IC chip 22 is disconnected. And the antenna 23 can be prevented from being damaged. Further, since the non-woven fabric 60 arranged in the accommodating recess 41 functions as a cushioning material, when pressure is applied to the non-contact data receiving / transmitting body 10 in the thickness direction, the non-woven fabric 60 is added to the IC chip 22. The pressure applied can be relieved and the IC chip 22 can be prevented from being damaged.

Since the non-contact data receiving / transmitting body 10 of the present embodiment is covered with the first covering member 40 and the second covering member 50 formed by injection molding, it is used outdoors by installing it on the asphalt-paved ground. It is also excellent in waterproofness and can be used outdoors for a long period of time.

Further, in the non-contact data receiving / transmitting body 10 of the present embodiment, the first covering member 40 is planar with the planar first connecting portions 44 and 44 connecting the two adjacent antenna covering portions 40B. Since it has the second connecting portions 45 and 45, the strength between the two adjacent antenna covering portions 40B is high, and it is not easily damaged even if it is stepped on by an automobile.

Further, the non-contact data receiving / transmitting body 10 of the present embodiment has a shape (hill shape) in which the first covering member 40 has a central portion 46 on the upper surface 40a as a top and is gently inclined from the top toward the outer edge. None, the outer edge of the central covering portion 40A of the first covering member 40 (the outer edge of the first connecting portion 44 and the second connecting portion 45) is formed diagonally (tapered) so as to gradually widen as the distance from the central portion increases. Moreover, since the outer edge of the antenna covering portion 40B of the first covering member 40 is formed diagonally (tapered) so that the width gradually increases as the distance from the central portion increases, the upper surface 40a of the first covering member 40 It is difficult for water droplets to collect on the taper. As a result, the non-contact data receiving / transmitting body 10 can prevent deterioration of communication characteristics due to adhesion of water droplets or the like.
Further, the non-contact data receiving / transmitting body 10 of the present embodiment has an antenna covering between the central covering portion 40A and the antenna covering portion 40B on the upper surface 40a of the first covering member 40 in the thickness direction of the antenna covering portion 40B. Since the groove 47 recessed from the portion 40B is formed, it is more difficult for water droplets and the like to collect on the upper surface 40a of the first covering member 40.

Further, in the non-contact data receiving / transmitting body 10 of the present embodiment, as the outer edge of the central covering portion 40A of the first covering member 40 (the outer edge of the first connecting portion 44 and the second connecting portion 45) moves away from the central portion. It is formed diagonally (tapered) so that the width gradually increases, and the outer edge of the antenna covering portion 40B of the first covering member 40 gradually widens (tapered) as the distance from the central portion increases. Since it is formed, when it is installed on the ground paved with asphalt via an adhesive, it has a high degree of adhesion to the ground and is unlikely to be displaced even when an external force is applied.

In the present embodiment, the case where the first covering member 40 has the first connecting portions 44 and 44 and the second connecting portions 45 and 45 is illustrated, but the present invention is not limited thereto. In the present invention, the first covering member may have at least a pair of planar connecting portions for connecting the antenna covering portions.

Next, a method of using the non-contact data receiving / transmitting body 10 of the present embodiment will be described.
The non-contact data receiving / transmitting body 10 of the present embodiment is installed and used, for example, on the asphalt-paved ground of a vast site where a large number of automobiles gather (hereinafter referred to as "vehicle storage place").
The IC chip 22 of the non-contact data receiving / transmitting body 10 records the position information of the vehicle storage place where the automobile is parked.
On the other hand, a vehicle parked in a vehicle storage area is provided with a non-contact data transmitter / receiver including an IC chip that records vehicle information about the vehicle and an antenna electrically connected to the IC chip. Examples of vehicle information include information indicating the attributes of each automobile. Specific examples of information indicating the attributes of automobiles include "manufacturer name", "vehicle type", "specifications", "inspected", "vehicles for specific customers", "domestic sales vehicles", "export vehicles", etc. Information can be mentioned.

After parking the vehicle at a predetermined position in the vehicle storage area, a non-contact data receiving / transmitting body installed in the vehicle by a reader (information reading device) and a non-contact data receiving / transmitting body 10 installed on the ground of the vehicle storage area 10 By reading and, the position information and the vehicle information are associated and registered in the system. As a result, it is possible to register in the system which vehicle is stopped at which position in the vehicle storage area.

In this way, it is possible to easily (efficiently) find the target vehicle from a large number of similar vehicles lined up in a vast vehicle storage space. Therefore, the work time for finding a car can be shortened and the work efficiency can be improved. In addition, it is possible to prevent mistakes in vehicle entry / exit management.

As shown in FIG. 10, the non-contact data receiving / transmitting body 100 of the present embodiment is roughly composed of an inlet 20 having a hard substrate 21 and a covering member 30 covering the inlet 20.

The non-contact data receiving / transmitting body 100 of the present embodiment differs from the non-contact data receiving / transmitting body 10 of the first embodiment described above in that the first covering member 40 is adjacent to two antenna covering portions 40B. It is a point having planar second connecting portions 45, 45, 45, 45 connecting the spaces.
