Since the 1st hole is provided in the said 1st housing | casing downward surface, the opening direction becomes downward rather than a horizontal surface. Therefore, even if a liquid (for example, rain) falls on the vehicle information terminal from above, there is a low risk that the liquid will enter the first housing from the first hole. Therefore, even if a waterproof structure is not provided at the connection portion between the first housing and the arm, the waterproofness of the first housing can be ensured according to the above configuration.

The portable navigation 100 is a device having a function as a known navigation device that performs route guidance and the like (hereinafter referred to as a navigation function). In addition, the portable navigation 100 has a function of positioning the current position based on a navigation signal transmitted from a positioning satellite used in a GNSS (Global Navigation Satellite System) (hereinafter referred to as a sub-function for realizing a navigation function). GNSS function). Note that GNSS includes GPS (Global Positioning System), Galileo, GLONASS, and the like.

  The portable navigation 100 has a wide area communication function and a narrow area communication function in addition to the navigation function and the GNSS function. The wide area communication function is a function of performing wireless access to a wide area communication network such as a cellular phone network and communicating with a communication device (for example, a center) existing outside the vehicle. For convenience, communication via a wide area communication network is referred to as wide area communication in order to distinguish it from communication based on other systems. As a communication method for realizing wide area communication, any mobile communication method can be adopted. Here, as an example, it is assumed that the portable navigation 100 performs wide-area communication in accordance with the LTE (Long Term Evolution) standard.

  The narrow-area communication function performs wireless communication with equipment (hereinafter referred to as a roadside device) arranged on a road without using a wireless base station or the like (that is, directly) in accordance with a predetermined communication method. It is a function. For example, DSRC (Dedicated Short Range Communications) based on wireless LAN technology, WAVE (Wireless Access in Vehicular Environment) standard disclosed in IEEE 1609, etc. are adopted as a communication method for realizing the narrow area communication function. be able to. Here, it is assumed that the portable navigation 100 is configured to communicate with a roadside machine or the like using DSRC.

  The roadside machine is installed above the road (for example, a position where the height from the road surface is 5 m or more) so as to distribute information toward a limited area on the road. The information distributed by the roadside machine is, for example, road traffic information such as traffic jams and accidents, safe driving support information, and the like. As another aspect, the roadside machine may be a communication facility that constitutes an automatic toll collection system that performs payment processing of toll road usage charges provided at the entrance and exit of toll roads. The narrow area communication function may perform communication with a communication device that provides a narrow area communication function mounted on another vehicle. That is, the narrow area communication function may provide inter-vehicle communication.

<About the configuration of the portable navigation 100>
Next, an example of the configuration of the portable navigation 100 for realizing the various functions described above will be described. As shown in FIGS. 2 and 3, the portable navigation system 100 includes two cases, a main case 1 and a holder case 2, which are connected by an arm 3. The arm 3 is configured to support the posture of the main case 1 with respect to the holder case 2. The arm 3 is a tubular member curved in an arcuate shape, and is configured to allow the flexible cable 4 to pass therethrough. For convenience, the direction from the main case 1 to the holder case 2 is referred to as a depth direction. The arrow in FIG. 2 indicates the depth direction. The main case 1 corresponds to the first casing described in the claims, and the holder case 2 corresponds to the second casing described in the claims.

  The main case 1 accommodates a display 5, a touch panel 6 stacked on the display surface 51 of the display 5, and a first substrate 7 that is a printed circuit board on which various electronic components are arranged. The holder case 2 accommodates a second substrate 8 that is a printed circuit board on which various electronic components are mounted. The 1st board | substrate 7 and the 2nd board | substrate 8 are connected so that mutual communication is possible by the flexible cable 4 which let the inside of the arm 3 pass.

  As described at the beginning, this portable navigation device 100 is a device that is premised on being arranged and used so that the display surface 51 of the display 5 faces the driver's seat. Therefore, in the portable navigation 100, the vertical direction and the horizontal direction are set so as to correspond to the orientation of the display screen of the display 5.

  The portable navigation 100 is configured on the assumption that the left and right direction of the main case 1 is attached to the vehicle so that the horizontal direction of the main case 1 is parallel to the horizontal plane for the vehicle (hereinafter referred to as the vehicle horizontal plane) and the vertical direction coincides with the height direction of the vehicle. Has been. Note that the left-right direction and the up-down direction for the main case 1 are determined in accordance with the display direction of the display 5, similarly to the up-down and left-right directions for the portable navigation 100. The state indicated by the match here is not limited to a complete match. It also includes a state in which the person sitting in the driver's seat is inclined enough to recognize the display contents on the display 5 without a sense of incongruity. The vehicle horizontal plane is a plane perpendicular to the height direction of the vehicle.

  The portable navigation 100 may be attached to the vehicle via, for example, a vehicle attachment bracket 300 attached to the windshield 200 with a double-sided tape or the like. The vehicle mounting bracket 300 is a member that holds the portable navigation 100. By attaching the holder case 2 to the vehicle mounting bracket 300, the portable navigation system 100 is locked to the vehicle. FIG. 4 is an external perspective view of a state in which the portable navigation 100 and the vehicle mounting bracket 300 are integrated.

  The installation position of portable navigation 100 on windshield 200 may be determined by the user. The portable navigation system 100 is preferably arranged in the peripheral visual field, particularly in the effective visual field in a state where the driver's seat occupant is looking in the front direction of the vehicle. The portable navigation 100 according to the first embodiment is assumed to be used by being mounted at the same height as the driver's seat occupant's line of sight.

  The shape of the main case 1 may be designed as appropriate. Here, as an example, it is assumed that the main case 1 is formed in a flat rectangular parallelepiped shape whose thickness direction is a direction perpendicular to the first substrate 7. The thickness of the main case 1 only needs to be large enough to accommodate predetermined objects such as the display 5, the touch panel 6, and the first substrate 7. The thickness direction substantially coincides with the aforementioned depth direction. In the main case 1, the surface parallel to the first substrate 7 is formed in a rectangular shape whose length in the left-right direction is longer than the length in the vertical direction.

  The shape of the holder case 2 may be designed as appropriate. Here, as an example, it is assumed that the holder case 2 is formed in a flat rectangular parallelepiped shape whose thickness direction is a direction perpendicular to the second substrate 8. The thickness of the holder case 2 only needs to be large enough to accommodate the second substrate 8 on which various electronic components are mounted.

  Reference numeral 21 shown in FIG. 2 represents a surface (hereinafter referred to as a holder upper surface portion) facing relatively upward in the holder case 2 when the portable navigation 100 is attached to the vehicle in a correct posture (hereinafter referred to as a formal posture). . Reference numeral 22 indicates a surface of the holder case 2 opposite to the holder upper surface portion 21 (hereinafter referred to as a holder lower surface portion). The holder lower surface portion 22 corresponds to a second housing downward surface described in the claims.

  Here, the formal posture is a mounting posture assumed when the portable navigation 100 is designed. The formal posture is a posture in which the display direction of the display 5 (that is, up, down, left, and right) is correct and the display surface 51 of the display 5 is directed to the driver's seat. Specific configurations of the main case 1, the holder case 2, and the arm 3 will be described later.

<About the contents of the main case 1>
Here, various configurations housed in the main case 1 will be described. The display 5 is a display device including a display surface 51 that displays various information. The display surface 51 provided in the display 5 is formed in a rectangular shape. Accordingly, the appearance of the display 5 is also a flat rectangular parallelepiped. For convenience, the surface of the display 5 opposite to the display surface 51 is referred to as a back surface portion. As described above, the portion of the main case 1 where the display surface 51 of the display 5 is disposed is an opening, and the display 5 is accommodated in the main case 1 so that the display surface 51 can be seen from the outside.

  As the display 5, a liquid crystal display, an organic EL display, or the like can be used. Here, as an example, the display 5 is assumed to be realized by using an LCD (Liquid Crystal Display) module. The display 5 is driven based on a control signal from a display controller, which will be described later, and displays an image.

  The touch panel 6 is a capacitive touch panel, for example, and is stacked on the display surface 51 of the display 5. The touch panel 6 sequentially outputs, to the touch panel controller 72, whether or not the touch panel 6 is touched by the user and, if touched, a signal indicating the touch position (hereinafter, touch position signal).

  Note that the touch panel 6 may be a touch panel that detects a user's touch position by a method other than the capacitance type (for example, a pressure-sensitive type). In addition, here, a configuration is disclosed in which the touch panel 6 is employed as a device (that is, an input device) for a user to input an instruction to the portable navigation 100, but the present invention is not limited thereto. A well-known device such as a hardware switch, a mouse, a haptic device, or the like can be used as the input device.

  The first substrate 7 is formed in a substantially rectangular shape. The first substrate 7 is accommodated in the main case 1 so as to face the back surface of the display 5. The circuit mounted on the first substrate 7 may be appropriately designed so as to provide a desired function. A circuit providing a desired function is realized by using various electronic components. Here, as an example, it is assumed that a display controller 71, a touch panel controller 72, a main control unit 73, a power supply circuit 74, and a main-side connector 75 are arranged on the first substrate 7. It should be noted that where the display controller 71, the touch panel controller 72, the main control unit 73, the power supply circuit 74, and the main-side connector 75 are arranged on the first substrate 7 may be appropriately designed.

  The display controller 71 is a component that controls the operation of the display 5. The display controller 71 is connected to the display 5 through a cable (not shown) so as to be able to communicate with each other. The display controller 71 is also connected to the main control unit 73 so that they can communicate with each other. The display controller 71 generates a control signal based on the display data input from the main control unit 73 and outputs the control signal to the display 5 to display an image corresponding to the display data.

  The touch panel controller 72 is a component that controls the operation of the touch panel 6. The touch panel controller 72 is connected to the touch panel 6 through a cable (not shown) so as to be able to communicate with each other. The touch panel controller 72 is also connected to the main control unit 73 so as to be able to communicate with each other. The touch panel controller 72 converts the touch position signal output from the touch panel 6 into data in a format that can be recognized by the main control unit 73 and provides the converted data to the main control unit 73.

  The main control unit 73 is configured as a computer including a CPU 731 as a central processing unit, a RAM 732 as a volatile memory, and a ROM 733 as a nonvolatile memory. The ROM 733 stores various programs for causing a normal computer to function as the main control unit 73.

  The main control unit 73 provides a navigation function by the CPU 731 executing a program stored in the ROM 733. Further, display data to be displayed on the display 5 is created based on data input from the touch panel controller 72 or the like and the program, and the display data is output to the display controller 71. In addition, in conjunction with a power supply circuit 74 described later, the portable navigator 100 is turned on / off.

  The power supply circuit 74 is a circuit that converts a power supply voltage supplied from a power supply (not shown) into an operation voltage suitable for the operation of each unit included in the portable navigation 100. The operating voltage generated by the power supply circuit 74 is supplied to each unit. The power source may be a battery built in portable navigation 100 or an in-vehicle battery. In the case where the in-vehicle battery is used as the power source of the portable navigation 100, the portable navigation 100 is connected to the in-vehicle battery through a power cable (not shown).

  The main connector 75 is a connector for electrically connecting the flexible cable 4 and the first substrate 7. That is, the first substrate 7 is connected to one end of the flexible cable 4 via the main-side connector 75. Note that the other end of the flexible cable 4 is electrically connected to the second substrate 8 via a holder-side connector 87.

  The main side connector 75 is disposed at a position facing the main side wiring hole 14 described later on the first substrate 7. Hereinafter, when the main-side connector 75 and the holder-side connector 87 are not distinguished, they are described as connectors.

  The function provided by the circuit mounted on the first substrate 7 corresponds to the first function recited in the claims. Specifically, each of a function for controlling display on the display 5 based on a user operation on the touch panel 6, a power control function, a function for performing arithmetic processing using data provided from various communication modules described later, and the like. Corresponds to the first function described in the claims.

<Configuration of Second Substrate 8>
Here, the configuration of the second substrate 8 accommodated in the holder case 2 will be described. The second substrate 8 is formed in a substantially rectangular shape and is accommodated in the holder case 2 so as to face the holder upper surface portion 21. The second substrate 8 includes an upper side surface 8A that faces relatively upward and a lower side surface 8B that faces relatively downward when the main case 1 is arranged in a correct posture.

  The circuit mounted on the second substrate 8 may be appropriately designed so as to provide a predetermined second function. Here, as an example, it is assumed that the GNSS antenna 81, the GNSS module 82, the DSRC antenna 83, the DSRC module 84, the LTE antenna 85, the LTE module 86, and the holder side connector 87 are arranged on the second substrate 8.

  The GNSS antenna 81 is an antenna for receiving a navigation signal transmitted by a positioning satellite (hereinafter referred to as a GNSS satellite) provided in the GNSS. For example, the GNSS antenna 81 may be an antenna that receives circularly polarized waves in the 1.5 GHz band. The GNSS antenna 81 is electrically connected to the GNSS module 82 and outputs an electrical signal corresponding to the received radio wave.

  The GNSS antenna 81 is arranged on the upper side surface 8A such that the center of directivity faces the direction from the lower side surface 8B toward the upper side surface 8A (hereinafter, the second substrate orthogonal direction). The state where the center of directivity is oriented in the second substrate orthogonal direction is not limited to the state where the directivity center completely coincides with the second substrate orthogonal direction. The center of directivity may be shifted by about 45 ° from the direction orthogonal to the second substrate.

  The GNSS module 82 executes arithmetic processing such as positioning of the current position based on the signal received by the GNSS antenna 81. The GNSS module 82 is connected to the holder-side connector 87. Thereby, the GNSS module 82 is connected to the main control unit 73 through the holder-side connector 87 and the flexible cable 4 so as to be able to communicate with each other. The place where the GNSS module 82 is installed on the second substrate 8 may be designed as appropriate. For example, it may be arranged near the position corresponding to the back side of the GNSS antenna 81 on the lower surface 8B. The GNSS antenna 81 and the GNSS module 82 are components for realizing the above-described GNSS function.

  The DSRC antenna 83 is an antenna for transmitting and receiving radio waves in a frequency band (for example, 5.8 GHz band) adopted as a carrier wave in DSRC. The DSRC antenna 83 is provided such that the center of directivity faces the second substrate orthogonal direction on the upper side surface 8A. The DSRC antenna 83 is electrically connected to the DSRC module 84.

  The DSRC module 84 is connected to the main control unit 73 via the holder-side connector 87, the flexible cable 4, and the like. The DSRC module 84 demodulates the signal received by the DSRC antenna 83 and provides it to the main control unit 73. In addition, data input from the main control unit 73 is modulated and output to the DSRC antenna 83 to be radiated as radio waves. The place where the DSRC module 84 is installed on the second substrate 8 may be appropriately designed. For example, it may be arranged near the position corresponding to the back side of the DSRC antenna 83 on the lower side surface 8B. The DSRC antenna 83 and the DSRC module 84 are configured to realize the above-described narrow area communication function.

  The LTE antenna 85 is an antenna for transmitting and receiving radio waves in a frequency band adopted as a carrier wave in the LTE standard. The LTE antenna 85 is provided on the upper side surface 8A so that the center of directivity faces the second substrate orthogonal direction. The LTE antenna 85 is electrically connected to the LTE module 86.

  The LTE module 86 is connected to the main control unit 73 via the holder-side connector 87, the flexible cable 4, and the like. The LTE module 86 demodulates the signal received by the LTE antenna 85 and provides it to the main control unit 73. In addition, data input from the main control unit 73 is modulated and output to the LTE antenna 85 to be radiated as radio waves. The place where the LTE module 86 is installed on the second substrate 8 may be designed as appropriate. For example, it may be arranged in the vicinity of a position corresponding to the back side of the LTE antenna 85 on the lower side surface 8B.

  The holder-side connector 87 is a connector for electrically connecting the flexible cable 4 and the second substrate 8. That is, the second substrate 8 is connected to one end of the flexible cable 4 via the holder-side connector 87. Thereby, the second substrate 8 and the first substrate 7 are electrically connected. The holder-side connector 87 is disposed at a position facing the holder-side wiring hole 23 formed in the holder lower surface portion 22 on the lower side surface 8B.

  The arrangement of various antennas on the upper side surface 8A may be appropriately designed. Each antenna is preferably arranged at a position where it is difficult to interfere with other antennas. The various antennas are preferably planar antennas such as patch antennas and plate-like inverted F antennas. According to such a configuration, the thickness of the holder case 2 can be reduced.

  The function provided by the circuit module mounted on the second substrate 8 corresponds to the second function described in the claims. That is, in the first embodiment, each of the GNSS function, the narrow area communication function, and the wide area communication function corresponds to the second function described in the claims.
