Description

  The present invention relates to an in-vehicle communication terminal device, and more particularly to an in-vehicle communication terminal device that performs information communication about vehicle passage information with a stationary communication terminal device that is mounted on a vehicle and installed at an entrance of a highway or the like. .

Recently, an ETC system has become widespread as a system that pays a fee when a vehicle passes an entrance / exit of an expressway. In this ETC system, automatic payment of fees is performed between the in-vehicle communication terminal device in which vehicle passing information is installed in the vehicle instead of the conventional ticket and the stationary communication terminal device installed at the toll gate. Since the vehicle can be passed without stopping at the toll gate, it is possible to eliminate the troublesome processing for paying the fee and smooth the traffic.
In this type of conventional ETC system, it is necessary to mount an in-vehicle communication terminal device that performs information communication on vehicle passage information with a stationary communication terminal device. By installing the ETC card, it is necessary to write information about the fee on the ETC card.
In addition, in the conventional in-vehicle communication terminal device, the ETC card is dropped from the connector while the information is being transmitted to the ETC card due to vibration or the like while the vehicle is running, or the ETC card that is transmitting information moves. In order to prevent the occurrence of a problem that accidentally destroys the recorded data, it is necessary to attach the ETC card to the card connector.

  As a conventional card connector of this type, both ends of an ETC card on which information is recorded are detachably held while being guided by guide grooves having substantially the same thickness as the ETC card, and information is transmitted to this card. A connector main body, a case for supporting the connector main body slidably in the insertion / extraction direction of the ETC card, an elastic member that constantly urges the connector main body in the direction of removing the ETC card, and a connector main body slid in the insertion direction of the ETC card There is a lock means for holding the lens in a predetermined position and a lock release means for releasing the hold by the lock means (for example, see Patent Document 1).

In this card connector, since the contact is forcibly elastically deformed by the ETC card with the ETC card inserted into the receiving space, the contact pressing portion pushes the tip of the ETC card upward and the housing The cover member is pressed against the lower surface. For this reason, the front end portion of the ETC card is held between the pressing portion of the contact and the lower surface of the cover member, so that the ETC card is surely held in the receiving space.
Japanese Patent Laid-Open No. 2002-8778

However, in such a card connector, both ends of the ETC card are detachably held while being guided by guide grooves having substantially the same thickness as the ETC card. There is a gap between them. Since the holding force in the receiving space of the ETC card acts only on the pressing portion of the contact, it is not possible to sufficiently suppress the rattling in the vertical direction with respect to the ETC card surface, and the ETC card is moved vertically by the vibration of the vehicle. There is an adverse effect that it vibrates in the direction and damages the contact portion. In particular, when an in-vehicle communication terminal device is mounted on a motorcycle, the impact due to vibration is greater than that of a passenger car, and damage to contact portions and the like is likely to occur.
The present invention has been made to solve these problems, and can absorb the vibration of the IC card received from the vibration of the vehicle, etc., and securely connect the IC chip and the connection terminal in the IC card, An in-vehicle communication terminal device capable of preventing damage to an IC card due to vibration is provided.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIGS. 1-10 is a figure which shows one Embodiment of the vehicle-mounted communication terminal device based on this invention, and has shown the example applied to the ETC card as an IC card.

First, the configuration will be described. 1 and 2, the in-vehicle communication terminal device 1 performs radio communication by radio waves with an ETC antenna provided in a stationary communication terminal device (not shown) of a toll booth in the ETC lane, and vehicle information, ETC card information It exchanges information such as billing information, and is attached to a four-wheel vehicle, a two-wheel vehicle or the like in an arbitrary posture.
The in-vehicle communication terminal device 1 is connected to a lower case 4 as a first storage member having a placement surface 3 on which an ETC card 2 is placed, and the lower case 4 via a hinge 5, and is connected to the lower case 4. An upper case 6 is provided as a second storage member that can be freely opened and closed.

  In the present embodiment, since the lower case 4 is attached to the vehicle with the lower side being used, the expressions of the lower case 4 and the upper case 6 are used, but the pivot center of the hinge 5 is used in the vertical direction. For example, the right case and the left case may be used.

A base end portion 7a of a buckle 7 is rotatably attached to the lower case 4, and an upper end portion 7b of the buckle 7 is swingable with the base end portion 7a as a fulcrum. The lower case 4, the upper case 6, and the buckle 7 are molded from a resin material.
When the upper end portion 7b of the buckle 7 is swung to an engagement position that engages with an engagement recess portion 6b (see FIG. 8) formed at the end portion of the upper case 6, the upper end portion 7b engages with the engagement recess portion 6b. The upper case 6 is firmly engaged with the lower case 4, and an end portion of the upper case 6 is formed so that a constant gap 24 (about 1 to 2 mm) is formed between the upper case 6 and the upper case 6. It forms in the taper shape which inclines upwards toward center part.
For this reason, when releasing the engagement of the buckle 7 in order to open the upper case 6, the user's fingertip can enter the gap 24 and the buckle 7 can be easily moved to the release position.
Further, as shown in FIG. 3, the ETC card 2 placed on the placement surface 3 is provided with an IC chip 2a at the end, and the IC chip 2a includes a CPU, a memory, and an input / output interface. Vehicle information, ETC card information, billing information, and the like are stored.

  On the other hand, the mounting surface 3 has a convex planar shape with respect to the lower case 4, and a step is formed with the lower case 4 (see FIG. 6C). Further, guide rails 8a protrude from both ends of the mounting surface 3 in the short direction, and the guide rails 8a extend in the longitudinal direction of the ETC card 2, and the guide rail 8a causes the short of the ETC card 2 to extend. Both ends in the hand direction are positioned (see FIG. 4).

Further, a pair of stopper pieces (first positioning members) 8b are provided at the end of the mounting surface 3, and the stopper pieces 8b abut on one end in the longitudinal direction (one end in the orthogonal direction) of the ETC card 2. Thus, one end of the ETC card 2 in the longitudinal direction is positioned on the placement surface 3.
The upper case 6 is provided with a protruding piece 6a as a second positioning member. The protruding piece 6a extends in a direction substantially perpendicular to the extending direction of the guide rail 8a, and the upper case 6 is closed. The other end in the longitudinal direction (the other end in the orthogonal direction) of the ETC card 2 is positioned on the placement surface 3 so as to be located outside the placement surface 3.
A holding piece 9 is provided at one end of the guide rail 8a in the extending direction. The holding piece 9 is provided to face the placement surface 3, and a part of both ends of the ETC card 2 in the short direction is provided. It is held together with the mounting surface 3. The holding piece 9 may be provided only on one of the two guide rails 8a, or may not be provided on any of the guide rails 8a.

  The distance between the holding piece 9 and the placement surface 3 is preferably equal to or less than the thickness of the ETC card 2. However, when the distance between the holding piece 9 and the mounting surface 3 is equal to or less than the thickness of the ETC card 2, the distance is not set to prevent the ETC card 2 from being inserted between the holding piece 9 and the mounting surface 3. It goes without saying that it is necessary to do so.

  Further, the upper case 6 is provided with elastic sheets 10a and 10b as vibration absorbing means or vibration absorbing pieces. The elastic sheets 10a and 10b are used to place the ETC card 2 on the mounting surface 3 when the upper case 6 is closed. It comes to press toward. As shown in FIG. 2, when a plurality of elastic sheets are provided, for example, when two elastic sheets are provided, the upper case 6 is provided so that at least one of the elastic sheets 10a and 10b is in contact with the opposite side of the IC chip 2a. It is preferable that In this way, when the elastic sheet 10a is arranged, as shown in FIG. 5, when the upper case 6 is closed, a pressing force acts on the ETC card 2 in the direction of arrow A, The ETC card 2 is held between the elastic sheet 10a. When the ETC card 2 is sandwiched between the placement surface 3 and the elastic sheet 10a, a pressing force acts in the direction of arrow B due to the elasticity of the connection terminal 16a, and the connection terminal 16a and the IC chip 2a are securely connected.

  The elastic sheets 10a and 10b only need to absorb vibrations of the ETC card 2. For example, the elastic sheets 10a and 10b are formed of elastic resin such as polyurethane or silicone, rubber such as nitrile rubber or neoprene rubber, and thermoplastic elastomer. It may be done. Moreover, you may use a commercially available gel-like sheet, for example, a silicone gel sheet or a urethane gel sheet. The elastic sheets 10a and 10b have a thickness of 1 mm to 5 mm, and may have any size and shape, for example, a quadrangle, a circle, an ellipse, or a polygon having a length of 1 cm to 5 cm and a width of 1 cm to 5 cm. The elastic sheets 10a and 10b may be integrally formed by insert molding or the like when the upper case 6 is formed, or may be attached to the upper case 6 by adhesion or the like.

Further, the elastic sheets 10a and 10b have a function of preventing vibrations such as vibrations from being transmitted to a contact portion between the ETC card 2 and the connection terminal 16a or a contact portion between the ETC card 2 and the mounting surface 3 as they are. . In general, the anti-vibration function has two functions of vibration isolation and vibration attenuation.
The vibration isolation means, for example, that the forced vibration applied to the in-vehicle communication terminal device 1 according to the present invention is f, and the in-vehicle communication terminal device 1 in a state where the elastic sheets 10a, 10b are attached to the upper case 6 of the in-vehicle communication terminal device 1. If the natural frequency (the natural frequency is equivalent to the resonance frequency) is f0, it means that the frequency ratio represented by f ÷ f0 is √2 (about 1.4) or more. When this frequency ratio is √2 (about 1.4) or more, the vibration transmissibility representing vibration transmission is 1 or less, so that the vibration insulation is also expressed as vibration vibration transmissibility, and the vibration transmissibility is 1 It is also the following. That is, the fact that the forced vibration f applied to the in-vehicle communication terminal device 1 becomes difficult to be transmitted is called vibration isolation.
The vibration attenuation means that vibration energy is converted into heat or the like to suppress vibration. When the natural frequency and the forced vibration f applied to the in-vehicle communication terminal device 1 match, the vibration of the in-vehicle communication terminal device 1 is reduced. Suppressing amplification (resonance phenomenon).

  Since the elastic sheet 10a, 10b itself has an internal damping characteristic, the elastic sheet 10a, 10b functions as a spring in three directions, and mainly exhibits a function of vibration isolation. This vibration isolation function also acts at the resonance frequency, and can reduce the transmission rate (resonance magnification) at the time of resonance. As materials, sizes, thicknesses, and mounting locations of the elastic sheets 10a and 10b having such functions, in-vehicle communication incorporating the elastic sheets 10a and 10b in order to absorb the vibrations that are transmitted by exhibiting the desired vibration insulating function. The natural frequency of the terminal device 1 can be obtained by measurement or the like, and can be appropriately selected according to the result.

As this measuring method, the elastic sheets 10a and 10b are incorporated in the in-vehicle communication terminal device 1, and vibration is forcibly applied to the in-vehicle communication terminal device 1 from the outside such as a vibration tester, and the frequency is gradually changed (increase or decrease). ) Can be performed by confirming the frequency at which the amplitude of the in-vehicle communication terminal device 1 rapidly increases. The magnitude of the amplitude at the resonance frequency of the in-vehicle communication terminal device 1 incorporating the elastic sheets 10a and 10b and the in-vehicle communication terminal device not incorporating the elastic sheets 10a and 10b are compared, and the resonance frequency of the in-vehicle communication terminal device 1 incorporating the elastic sheets 10a and 10b is compared. It can be confirmed that the amplitude is reduced.
Furthermore, since the elastic sheets 10a and 10b have not only a vibration isolating function for absorbing periodic and continuous vibrations but also a buffer function for relaxing temporary and sudden force (impact energy), the elastic sheets 10a By utilizing the elasticity of 10b, the impact can be alleviated at the moment of impact. Therefore, the impact on the contact portion between the ETC card 2 and the connection terminal 16a, the contact portion between the ETC card 2 and the mounting surface 3, and the like can be mitigated, and damage to the ETC card 2 can be prevented.

  As described above, since the elastic sheets 10a and 10b are provided in the upper case 6, the vibration of the ETC card 2 received from the vibration of the vehicle is sufficiently absorbed by the elastic sheets 10a and 10b, and the IC chip 2a in the ETC card 2 is obtained. And the connection terminal 16a are securely connected, and damage to the ETC card 2 due to vibration is prevented.

The upper case 6 is provided with a pair of protrusions (first protrusions) 11 that protrude toward the holding piece 9. One protrusion 11 may be provided.
As shown in FIG. 6C, the lower case 4 located outside the placement surface 3 is provided with a protrusion (second protrusion) 4a, and this protrusion 4a is higher than the height of the placement surface 3. It is formed at almost the same height. The protrusion 4a is provided at a position close to the protruding piece 6a when the upper case 6 is closed.

The lower case 4 incorporates a circuit board (control means) 13 for controlling the in-vehicle communication terminal device 1, and the lower case 4 has a through hole through which the connection terminal 16 a of the circuit board 13 protrudes from the mounting surface 3. 12 is formed.
The through hole 12 is formed at a position facing the IC chip 2a when the ETC card 2 is placed on the placement surface 3 and one end in the longitudinal direction of the ETC card 2 contacts the stopper piece 8b. The IC chip 2a is brought into contact with the connection terminal 16a.
Further, the connection terminal 16a is made of a flexible conductive member, and the upper case 6 is closed by elastic contact with the IC chip 2a, and the ETC card 2 is mounted by the elastic sheets 10a and 10b. When pressed against the mounting surface 3, the pressing force acts on the ETC card 2 in the direction of the holding piece 9 against the pressing force of the elastic sheet 10a.

FIG. 7 is a block diagram of the circuit board 13 built in the lower case 4.
In FIG. 7, the circuit board 13 includes a power supply circuit 14, a control circuit 15, an IC chip read / write circuit 16, a display processing circuit 17, and a wireless circuit 18.
The control circuit 15 includes a CPU (Central processing unit), a ROM (Read only memory), and a RAM (Random access memory), and controls the entire in-vehicle communication terminal device 1 according to a predetermined sequence. .
The power supply circuit 14 is supplied with 12V power from a battery provided in the vehicle via the wiring 19, and supplies power to the circuit board 13.
The IC chip read / write circuit 16 reads the vehicle information, ETC card information, billing information, etc. stored in the IC chip 2a via the connection terminal 16a, and stores the vehicle information, ETC card information, billing information, etc. It has become.
The display processing circuit 17 is connected to the LED lamp 22 via the wiring 20 and controls the lighting of the LED lamp 22.
When the IC chip 2a is detected by the IC chip read / write circuit 16, the control circuit 15 outputs a command signal to the display processing circuit 17 and turns on the LED lamp 22 to confirm the operation.
The radio circuit 18 is connected to the antenna 23 via the wiring 21, and performs radio communication with the ETC antenna using a high frequency of a predetermined frequency band, for example, a high frequency of 5.8 GHz band. .

When the ETC card 2 is attached to the in-vehicle communication terminal device 1 having such a configuration, the upper case 6 is opened by moving the buckle 7 to the release position (see FIG. 2), and in this state, along the guide rail 8a. The ETC card 2 is slid on the placement surface 3.
When one end in the longitudinal direction of the ETC card 2 is inserted between the holding piece 9 and the placement surface 3 and comes into contact with the stopper piece 8b, the entire surface of the ETC card 2 is placed on the placement surface 3 and is connected to the connection terminal 16a. The IC chip 2a comes into contact.
At this time, the connection terminal 16a presses the ETC card 2 toward the holding piece 9, the ETC card 2 is held by the connection terminal 16a and the holding piece 9, and does not come out of the lower case 4. In particular, when the vehicle-mounted communication terminal device 1 is mounted on a motorcycle or the like, the ETC card 2 does not fall from the lower case 4 when the rotation center of the hinge 5 is set in the vertical direction.

Next, the upper case 6 is closed, and the upper case 6 is fixed to the lower case 4 by swinging the buckle 7 to the engaged position. At this time, both ends in the longitudinal direction and both ends in the short direction of the ETC card 2 are positioned on the mounting surface 3 by the guide rail 8a, the stopper piece 8b, and the protruding piece 6a, and the elastic sheet 10a as described above. 10b presses the ETC card 2 toward the placement surface 3, thereby reliably bringing the IC chip 2a into contact with the connection terminal 16a.
Further, the connection terminal 16a presses the ETC card 2 toward the holding piece 9 against the pressing force of the elastic sheet 10a, and the ETC card 2 is firmly held by the lower case 4 by the holding piece 9 and the connection terminal 16a. .
Further, when removing the ETC card 2 from the in-vehicle communication terminal device 1, the buckle 7 is moved to the release position to open the upper case 6, and in this state, the ETC card 2 is placed along the guide rail 8a. Slide it up and remove it from the mounting surface 3.

As described above, in the present embodiment, the lower case 4 having the placement surface 3 on which the ETC card 2 is placed, the upper case 6 provided to be openable and closable with respect to the lower case 4, and the lower case 4 Since the holding piece 9 that is provided facing the placement surface 3 and holds the ETC card 2 together with the placement surface 3 is provided, the ETC card is placed on the placement surface 3 of the lower case 4 with the upper case 6 opened. 2 and the ETC card 2 can be held by the holding piece 9 and the mounting surface 3, and the ETC card 2 can be attached to the in-vehicle communication terminal device 1 using a wide space.
Further, when the ETC card 2 is taken out from the lower case 4, the ETC card 2 can be taken out from the mounting surface 3 with the upper case 6 opened, so that the ETC card 2 is mounted on the in-vehicle communication terminal device using a wide space. 1 can be removed.
As a result, the ETC card 2 can be easily attached and detached. Further, since the ETC card 2 can be held by the holding piece 9 and the mounting surface 3 even after the ETC card 2 is mounted, the ETC card 2 is displaced with respect to the lower case 4 due to vibrations during traveling of the vehicle. It is possible to prevent occurrence of reading failure or storage failure of information stored in the ETC card 2.

Further, in the present embodiment, the connection terminal 16a is exposed from the through hole 12 and is elastically brought into contact with the ETC card 2 so that the ETC card 2 is attached to the holding piece 9 when the upper case 6 is opened. Since it is pressed, the ETC card 2 can be more reliably held by the lower case 4.
On the other hand, it is conceivable that the ETC card 2 rides on the holding piece 9 for some reason by attaching the ETC card 2 to the lower case 4 (see FIG. 9).
In this case, the ETC card 2 may be mounted incorrectly, and the IC chip 2a may not come into contact with the connection terminal 16a. Therefore, reading errors or storage errors of information stored in the IC chip 2a may occur. End up. Further, the upper case 6 may be closed without the user's knowledge, and the ETC card 2 may be damaged.
In the present embodiment, since the upper case 6 is provided with the projection 11 protruding toward the holding piece 9, the ETC card 2 is held by the ETC card 2 being poorly mounted when the ETC card 2 is attached to the lower case 4. When the upper case 6 is closed while riding on the piece 9, the thick case 11 contacts the holding piece 9 through the ETC card 2 so that the upper case 6 is not completely closed. (See FIG. 10).
For this reason, it is possible to prompt the user to recognize that the ETC card 2 is not properly mounted and to normally mount the ETC card 2, and to prevent the reading failure or the storage failure of the information stored in the ETC card 2. be able to.

In the present embodiment, the lower case 4 is provided with guide rails 8a for positioning both ends of the ETC card 2 in the short direction and stopper pieces 8b for positioning one end of the ETC card 2 in the longitudinal direction. Since the protruding piece 6a for positioning the other end in the longitudinal direction of the ETC card 2 is provided, the ETC card 2 can be easily positioned on the lower case 4, and vibrations during traveling of the vehicle after the ETC card 2 is mounted. It is possible to further prevent the ETC card 2 from being displaced with respect to the lower case 4 due to the above.
In the present embodiment, since the upper case 6 is provided with the protruding piece 6a for positioning the other end in the longitudinal direction of the ETC card 2, the ETC card 2 is attached to the lower case 4 with the upper case 6 opened. In addition, the other end of the ETC card 2 in the longitudinal direction is prevented from being caught by the protruding piece 6 a, that is, the ETC card 2 is easily removed from the lower case 4 without a member caught on a part of the periphery of the ETC card 2. be able to.

Further, in the present embodiment, when a protrusion 4a having a height substantially the same as the height of the mounting surface 3 is provided on the outer side of the mounting surface 3 of the lower case 4, the protrusion 4a is closed when the upper case 6 is closed. Since it is provided at a position close to the protruding piece 6a, the following effects can be obtained.
As shown in FIG. 6 (a), even when the protrusion 4a is not provided, when the ETC card 2 is normally attached to the placement surface 3, the other end in the longitudinal direction of the ETC card 2 is normal by the protruding piece 6a. Is positioned.
However, when the upper case 6 is closed with the other end in the longitudinal direction of the ETC card 2 being displaced outwardly from the placement surface 3, the protruding piece 6a can be moved in the longitudinal direction of the ETC card 2 or the like without the projection 4a. There is a possibility that the ETC card 2 may be bent by colliding with the end (see FIG. 6B).
On the other hand, in the present embodiment, as shown in FIG. 6C, when the upper case 6 is closed, the placement surface 3 is disposed outside the placement surface 3 adjacent to the protruding piece 6a. Since the protrusion 4a having the height substantially the same as the height is provided, when the upper case 6 is closed with the other end in the longitudinal direction of the ETC card 2 being displaced outward from the placement surface 3, the protruding piece 6a becomes the ETC. Even if it collides with the other end in the longitudinal direction of the card 2, the other end in the longitudinal direction of the ETC card 2 can ride on the protrusion 4a to be the same height as the placement surface 3, and the ETC card 2 is bent. Can be prevented.

  As described above, in the in-vehicle communication terminal device 1 according to the present invention, the lower case 4 having the placement surface 3 on which the ETC card 2 is placed, and the lower case 4 are provided so as to be openable and closable. An elastic sheet 10a that is provided in the upper case 6 and the lower case 4 and includes a circuit board 13 that can read and write information stored in the ETC card 2, and absorbs the vibration of the ETC card 2. 10b is provided, when the upper case 6 is closed, the vibration of the ETC card 2 transmitted from the vehicle or the like is transmitted by the elastic sheets 10a and 10b that absorb the vibration of the ETC card 2 provided in the upper case 6. When the IC chip 2a and the connection terminal 16a in the ETC card 2 are securely connected to each other, the reading failure of the information stored in the ETC card 2 and the occurrence of the storage failure are prevented. To, damage to the ETC card 2 is prevented due to vibration.

  In the in-vehicle communication terminal device 1, when the upper case 6 is closed, the elastic sheets 10 a and 10 b press the ETC card 2 placed on the lower case 4 against the placement surface 3, and the ETC card 2 Since the mounting surface 3 is sandwiched, the IC chip 2a and the connection terminal 16a in the ETC card 2 are securely connected, and reading of information stored in the ETC card and occurrence of memory failure are prevented and vibrations are prevented. Damage to the ETC card due to is prevented.

  In the in-vehicle communication terminal device 1, when the upper case 6 is closed, the upper case 6 is positioned so that at least 10 a of the elastic sheets 10 a, 10 b contacts the opposite side of the IC chip 2 a in the ETC card 2. Therefore, when the upper case 6 is closed, the elastic sheet 10a comes into contact with the opposite side of the IC chip 2a, and the IC chip 2a is directly pressed against the connection terminal 16a, so that the IC chip 2a is more reliably connected. The terminal 16a is connected, and the vibration of the ETC card 2 is absorbed, so that the reading of information stored in the ETC card 2 and the occurrence of memory failure are prevented and the damage of the ETC card 2 due to the vibration is prevented. .
