The body 1 includes a first opening 11 on one side and a second opening 12 on the other side. For understanding of the description of the present invention, one side may be the left side with reference to FIG. 1 , and the other side will be described as the right side with respect to FIG. 1 . The first opening 11 and the second opening 12 may communicate with the accommodation space 13 .

The coupling terminal 2 is disposed toward the first opening 11 in a state embedded in the body 1 , and is coupled to the OBD terminal O1 provided in the vehicle. The coupling terminal 2 may be electrically connected to the OBD terminal O1 to receive the seriousness detection information transmitted by the OBD network (electrically connected to the vehicle network O3, the ECU, etc.) provided in the vehicle.

The communication module 3 is provided on the body 1 and is connected to the coupling terminal 2 . Illustratively, the communication module 3 may be installed in the receiving space 13 of the body 1 . Although not shown, the communication module 3 may include a terminal electrically connected to a cable or circuit connected to the coupling terminal 2 . As described above, a board on which a cable or circuit is printed may be disposed or installed in the accommodation space 13 .

The communication module 3 may be electrically connected to the coupling terminal 2 by the above method and the like to receive the diagnostic detection information. At this time, the communication module 3 receives the diagnostic detection information from the OBD terminal O1 and transmits it to the external device ED.

The communication module 3 may include a wireless communication module such as a Bluetooth module and a Wi-Fi module to transmit the sense-sensing information to an output device such as a smart phone. That is, the communication module 3 may provide Bluetooth and Wi-Fi communication.

The receiving terminal 4 is disposed toward the second opening 12 in a state embedded in the body 1 , and is connected to the coupling terminal 2 . The receiving terminal 4 may be connected to a terminal of the OBD terminal O2.

The receiving terminal 4 is electrically connected to the coupling terminal 2 through a cable or circuit disposed or installed in the receiving space 13 of the body 1 described above, and the diagnosis transmitted from the coupling terminal 2 The detection information may be received, and the diagnosis detection information may be transmitted to the OBD terminal O2 through a connection terminal of the OBD terminal O2.

As such, the device is disposed toward the first opening 11 and is electrically connected to the coupling terminal 2 coupled to the OBD terminal O1, the coupling terminal 2 and communicatively connected to the external device ED. By including a receiving terminal 4 disposed toward the communication module 3 and the second opening 12 and connected to the coupling terminal 2 and electrically connected to the connection terminal of the OBD terminal O2, the external device (ED) The OBD terminal (O2) can be electrically connected to the OBD terminal (O1) without disconnecting the external device (ED) from the OBD terminal (O1) while connected to the OBD terminal (O1). And there is an advantage in that the electrical connection between each of the external devices ED and the OBD terminal O1 and the release of the electrical connection are easy.

Also, to connect the OBD terminal (O2) to the OBD terminal (O1), it is not necessary to disconnect the external device (ED) and the OBD terminal (O1), so the connection of the external device (ED) (including the terminal and wireless communication device) There is an advantage in that it is possible to prevent the loss of information and to maintain a state in which the truth detection information can be checked in real time.

1 and 2 , the structure of the accommodation terminal 4 may be the same as that of the OBD terminal O1 . For example, when the OBD terminal O1 includes a PIN, the accommodating terminal 4 also includes a PIN, and the PIN arrangement of the accommodating terminal 4 may be the same as that of the OBD terminal O1.

As another example, when the OBD terminal O1 is a jack, the receiving terminal 4 is also a jack, and the jack of the OBD terminal O1 and the jack of the receiving terminal 4 may be structurally the same.

Through this, when the OBD terminal O2 is connected to the present device while the device is connected to the OBD terminal O1, there is an advantage in that the installation is easy because a separate gender is not required.

On the other hand, as described above, it was said that the body 1 can be formed of an insulating material such as resin, but the body 1 repeatedly contacts the vehicle, OBD terminal (O1), OBD terminal (O2), etc. to scratch the surface, Damage or deformation may occur.

In addition, when the body 1 comes in contact with water vapor in the atmosphere, etc., dew condensed by temperature, etc., the body 1 made of resin absorbs moisture to change the size, so the coupling terminal 2 and the receiving terminal 4 There may be problems such as changing the location of

In addition, when the body 1 is exposed to moisture, plasticization proceeds to soften it, or hydrolysis proceeds to lower impact resistance.

Therefore, the body 1 may include a protective film G provided on the outer surface in order to suppress the occurrence of the above problems.

On the other hand, when the body 1 is used for a long time with the protective film G applied, fine grooves are generated in the protective film G, so that the outer surface of the body 1 comes in contact with moisture or scratches, damage, deformation, etc. In order to confirm in real time, the body 1 needs to be maintained in a transparent state, and there is a need to check if a groove (hole) is generated for maintenance of the protective film G.

As a means for meeting the above needs, the protective film (G) film is a first transparent adhesive layer (G1) in contact with the outer surface of the body (1), a transparent heating layer (G2) provided on the first transparent adhesive layer (G1), A second transparent adhesive layer G3 provided on the transparent heating layer G2 and a variable protective layer G4 provided on the second transparent adhesive layer G3 may be included.

Each of the first transparent adhesive layer (G1) and the second transparent adhesive layer (G3) is 100 parts by weight of an acrylic monomer comprising 70 to 99% by weight of butyl acrylate and 1 to 30% by weight of acrylonitrile, 0.1 to 5 parts by weight of a radical initiator, and It may contain 0.01 to 20 parts by weight of a crosslinking agent.

Butyl acrylate has a glass transition temperature of 0°C or lower when polymerized with a homopolymer, and acrylonitrile has a glass transition temperature of 80°C or higher when polymerized with a homopolymer.

If the butyl acrylate is less than 70% by weight, the glass transition temperature is increased to decrease impact resistance, and there is a problem in that haze occurs. In addition, when the content exceeds 99% by weight, the glass transition temperature value is too low, there is a problem that abrasion resistance is poor, it is not preferable.

If the content of acrylonitrile is less than 1% by weight, the glass transition temperature is too low, so there is a problem that adhesion durability is reduced, and when the content exceeds 30% by weight, there is a problem that the initial adhesive strength is reduced, which is not preferable.

The radical initiator is used for polymerization of the acrylic monomer, and commercially available radical initiators may be used.

The crosslinking agent is added to crosslink the acrylate-based copolymer obtained by polymerizing butyl acrylate and acrylonitrile, and for example, hexanediol diacrylate may be used. If the content ratio of the crosslinking agent is less than 0.1 parts by weight, the sheet becomes flexible and cutability is reduced, thereby reducing productivity. .

Each of the first transparent adhesive layer G1 and the second transparent adhesive layer G3 may maintain an adhesive force at a high temperature while maintaining a transparent state. Of course, the first transparent adhesive layer (G1) and the second transparent adhesive layer (G3) may include other commercially available additives on the premise that they maintain adhesion at high temperature (about 37° C. or higher) and maintain a transparent state.

The transparent heating layer G2 is provided on the first transparent adhesive layer G1 to be described later, and is disposed between the first transparent adhesive layer G1 and the second transparent adhesive layer G3, and is indium tin oxide (Indium Tin Oxide). ), which generates heat when direct current or alternating current is applied, and is characterized by being transparent.

The variable protective layer (G4) is provided on the second transparent heating layer (G2), and is a first solution in which 3.84 g of N-isopropyl acrylamide (NIPAM) polymer and 1.25 g of sodium alginate are dissolved per 250 ml of distilled water; A converter in which a second solution containing 3% calcium chloride and 0.5% ammonium persulfate is mixed in 300 ml of distilled water and 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, 30 parts by weight of isopropyl alcohol up to parts of a protective agent.

The first solution and the second solution are degassed with nitrogen gas, respectively, and the first solution is added dropwise to the stirred second solution drop by drop with a syringe. At the same time as the dropping, microcapsules of calcium alginate are generated. . The polymerization of the encapsulated NIPAM is completed within 1 to 3 hours, and the obtained fine particles can be washed 3 to 7 times with distilled water.

These converters exist in a transparent state at about 37°C or less, and when the temperature exceeds 37°C, the uncrosslinked polymer in the fine particles becomes insoluble and becomes cloudy, so it is converted to an opaque state. When the temperature is lowered to 37° C. or less from the insoluble state, the converting agent is converted to a transparent state, and the transparent and opaque state can be reversibly changed.

5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, and 30 parts by weight or less of isopropyl alcohol are mixed with stirring for about 1 hour and then ultrasonically dispersed. and has excellent wear resistance, chemical resistance, corrosion resistance, weather resistance, and thermal stability.

In this way, the body 1 is provided with a protective film (G) including a protective agent excellent in abrasion resistance and water repellency on the outer surface, so that the body 1 in contact with moisture and the occurrence of scratches, breakage, deformation, etc. can be suppressed. There is an advantage.

As described above, as the body 1 is used for a long time in a state in which the protective film G is provided on the outer surface, microgrooves may be generated in the protective film G by an external force, and by these microgrooves, the body 1 ) may come in contact with moisture or cause scratches, deformation, or damage.

As described above, the protective film G is maintained in a transparent state at 37° C. or lower (see FIG. 3A ), so that it can be checked in real time whether deformation or scratches of the body 1 provided with the protective film G have occurred.

As described above, in order to confirm in advance that the protective film (G) is provided (attached) on the outer surface of the body (1) and used for a long time, such as grooves of the protective film (G), or the outer surface of the body (1) deformation, scratches , it is necessary to check the location of the grooves in the protective film (G) for maintenance of the protective film (G) in a state in which it is confirmed that contact with water, damage, etc. have occurred.

At this time. When electricity is applied to the transparent heating layer (G2), the transparent heating layer (G2) is heated and heat is transferred to the changing agent, and when the changing agent exceeds 37°C, the variable protective layer (G4) containing the protective agent is cloudy becomes opaque. On the other hand, the first transparent adhesive layer (G1), the transparent heating layer (G2), and the second transparent adhesive layer (G3) remain transparent, and the color of the body 1 that was in an opaque state and the cloudy variable protective layer (G4) ) are contrasted (see FIG. 3b ), so that the location of the grooves in the variable protective layer G4 can be easily identified (the color of the outer surface of the body 1 and the color of the variable protective layer G4 in an opaque state are Others are preferred).

As described above, since the second transparent adhesive layer (G3) maintains adhesive strength even at a high temperature exceeding 37°C, a variable protective layer (G4) is formed in the grooves generated in the variable protective layer (G4) attached to the outer surface of the body (1). It can be easily maintained by inserting a new one.

As such, the body 1 has the advantage of being able to protect the body 1 from external stimuli for a long period of time by including the easy-to-maintain protective film G4.

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
