FIG. 1 is a schematic view of a portable terminal holder 100 in a state in which a portable terminal 2 is held by a holding unit 3 installed in a vehicle 1. FIG. 2 is a block diagram of the portable terminal holder 100.

  The portable terminal holder 100 is portable based on the temperature sensor 5 that detects the ambient temperature of the portable terminal 2 held by the holding unit 3 and the detected temperature of the temperature sensor 5 in addition to the holding unit 3 and the charging unit 4. A determination unit 6 that determines whether or not the ambient temperature of the terminal 2 is suitable for use of the mobile terminal 2 and a notification unit 7 that notifies the determination result of the determination unit 6 are provided. Here, in this embodiment, the mobile terminal 2 is a smartphone such as iPhone (registered trademark), Android (registered trademark), and a WebOS platform.

  As shown in FIG. 1, the holding portion 3 is installed on an upper portion of a dashboard 9 in the vehicle 1 that is located below the windshield 8. And the holding | maintenance part 3 is comprised so that holding | maintenance of the portable terminal 2 is possible in the attitude | position in which the display screen of the held portable terminal 2 faces the driver | operator who is sitting in the driver's seat.

  The holding part 3 is provided at a base part 3a, an extended wall part 3b erected so as to extend upward from a rear end part of the base part 3a, and an upper end part of the extended wall part 3b. And a flange 3c. The base portion 3a is configured such that the lower end portion of the portable terminal 2 can be inserted into the rear end portion. The extended wall portion 3b includes a bent portion 3d that extends by bending both left and right ends forward, and the portable terminal 2 is configured to be detachable between the pair of left and right bent portions 3d. Then, in a state where the mobile terminal 2 is inserted between the pair of left and right bent portions 3d, the pair of left and right bent portions 3d abut against the lateral side portion of the mobile terminal 2 and hold the mobile terminal 2 in a stable posture. Yes. The eaves portion 3c is provided so as to extend forward from the upper end portion of the extending wall portion 3b, and the portable terminal 2 held by the holding portion 3 is exposed to direct sunlight (see the white arrow in the figure). It is preventing.

  The temperature sensor 5 is installed at an upper end portion of the flange portion 3c in the holding unit 3, and is installed in a portion of the holding unit 3 that is exposed to direct sunlight (see a white arrow in the figure). Thereby, the temperature sensor 5 detects the temperature on the high temperature side of the ambient temperature of the mobile terminal 2 held by the holding unit 3. The temperature detection by the temperature sensor 5 is always performed.

  As shown in FIG. 2, the charging unit 4 supplies power supplied from an external power source 10 such as a cigarette lighter power source and a power source for other uses to the holding unit 3 via a power supply circuit and a connector outside the figure. Charging is performed by supplying power to the held mobile terminal 2. For example, the portable terminal 2 is held by the holding unit 3 so that the lower part of the portable terminal 2 and the power supply circuit of the charging unit 4 are connected by a connector (not shown). Incidentally, when charging the mobile terminal 2, the power supplied from the external power source 10 is converted into a desired voltage by the voltage converter and supplied to the mobile terminal 2.

  The discriminating means 6 discriminates whether or not the temperature detected by the temperature sensor 5 is outside the allowable use set temperature range (for example, 5 to 35 ° C.) suitable for use of the mobile terminal 2. The notification unit 7 includes a display unit 11 that displays the determination result of the determination unit 6 and a communication unit 12 that communicates the determination result of the determination unit 6 to the portable terminal 2 held in the holding unit 3. . Here, the use allowable set temperature range can be appropriately changed and set. For example, when the temperature range suitable for use differs depending on the model of the portable terminal 2, the use allowable set temperature range suitable for use of the selected model can be set by selecting the model.

As shown in FIG. 1, the display unit 11 is, for example, a red display lamp such as an LED, and is installed on the front side of the base 3 a of the holding unit 3. When the temperature detected by the temperature sensor 5 is outside the allowable use set temperature range (for example, 5 to 35 ° C.) suitable for use of the mobile terminal 2, the display lamp blinks or lights up on the display unit 11.
The communication means 12 is connected to the portable terminal 2 held in the holding unit 3 from the portable terminal holder 100 by wireless communication using Bluetooth (registered trademark), Wi-Fi (registered trademark), or wired communication. Information about the determination result is communicated. In this case, for example, when the mobile terminal 2 receives information about the determination result, the determination result is notified by voice or displayed on the display screen, and the determination result is notified to the user. .

  As described above, the determination unit 6 determines whether or not the temperature detected by the temperature sensor 5 is outside the allowable use temperature range (for example, 5 to 35 ° C.). In addition, the discriminating means 6 estimates whether or not the detected temperature of the temperature sensor 5 falls outside the allowable use set temperature range before the detected temperature of the temperature sensor 5 falls outside the allowable use set temperature range. It is configured. That is, the determination unit 6 determines whether or not the ambient temperature of the mobile terminal 2 held by the holding unit 3 tends to increase or decrease based on the temperature detected by the temperature sensor 5, and then the temperature sensor It is estimated whether the detected temperature 5 is out of the allowable use temperature range.

  In this way, the determination unit 6 determines whether the ambient temperature of the portable terminal 2 is suitable for use of the portable terminal 2 based on the detected temperature of the temperature sensor 5, and the detected temperature of the temperature sensor 5 is permitted to be used. In addition to estimating whether or not the detected temperature of the temperature sensor 5 is outside the allowable use temperature range before the temperature is outside the set temperature range, the detected temperature of the temperature sensor 5 is actually set within the allowable use temperature range. It is determined whether it is outside.

  Here, the temperature detection by the temperature sensor 5 is repeatedly performed at a set cycle. For example, the determination unit 6 detects that the temperature detected by the current temperature sensor 5 is higher than the temperature detected by the previous temperature sensor 5. When the state continues continuously for the set number of times or more, it can be determined that the ambient temperature of the mobile terminal 2 held by the holding unit 3 is increasing. Then, for example, the determination unit 6 obtains an approximate line connecting the detected temperatures of the plurality of temperature sensors 5 determined to have an increasing tendency, and compares the approximate line with the upper limit temperature of the allowable use temperature range. It can be estimated whether the detected temperature of the temperature sensor 5 rises above the allowable use set temperature range before the set time elapses from the present time. In addition, the determination as to whether or not there is a downward trend and the estimation as to whether or not the temperature detected by the temperature sensor 5 falls below the allowable set temperature range should be performed in the same manner as in the case of the upward trend described above. Can do.

  In this way, the determination unit 6 estimates whether or not the ambient temperature of the portable terminal 2 held in the holding unit 3 is outside the allowable use set temperature range. The estimation result is notified. For example, in the display unit 11, when the determination unit 6 estimates that the ambient temperature of the mobile terminal 2 held in the holding unit 3 is outside the use allowable set temperature range, the display lamp is turned on. When the determination unit 6 determines that the temperature detected by the temperature sensor 5 is outside the allowable use temperature range, the display unit 11 blinks the display lamp. As described above, the display unit 11 displays the estimation result of the determination unit 6 and the display result of the determination unit 6 so that the display form is different, and which case is displayed. The user can grasp it. Further, in the same way as described above, the communication unit 12 communicates information about the estimation result of the determination unit 6 from the portable terminal holder 100 to the portable terminal 2 held in the holding unit 3 by wireless communication or wired communication. ing. In this case, for example, when the mobile terminal 2 receives information about the estimation result, the estimation result is notified by voice or displayed on the display screen, and the estimation result is notified to the user. .

  In addition, for example, when the determination unit 6 estimates that the ambient temperature of the mobile terminal 2 is outside the use allowable set temperature range, the determination unit 6 has a timing when the ambient temperature of the mobile terminal 2 reaches outside the use allowable set temperature range. You can also guess. In this case, the notification means 7 also notifies the timing estimated by the determination means 6 so that the user can grasp to what timing the use can be continued. Further, for example, when charging is performed by the charging unit 4, timing information estimated by the determining unit 6 by the communication unit 12 is communicated to the portable terminal 2, and charging of the portable terminal 2 is completed. And the timing estimated by the discriminating means 6 can be notified whether or not the charging of the portable terminal 2 can be completed.

In addition to estimation, it is determined whether or not the temperature detected by the temperature sensor 5 is actually outside the allowable use temperature range. Instead, the determination unit 6 only estimates whether or not the detected temperature of the temperature sensor 5 falls outside the allowable use set temperature range before the detected temperature of the temperature sensor 5 falls outside the allowable use set temperature range. But you can. In this case, the notification unit 7 notifies only the estimation result of the determination unit 6. Alternatively, the determination unit 6 may simply determine whether or not the temperature detected by the temperature sensor 5 is actually outside the allowable use temperature range. In this case, the notification unit 7 notifies only the determination result of the determination unit 6.

(3) In the above embodiment, one temperature sensor 5 is provided, but a plurality of temperature sensors may be provided. In this case, for example, the discriminating means 6 uses the highest detected temperature and the lowest detected temperature among the detected temperatures of the plurality of temperature sensors 5 so that the detected temperature of the temperature sensor 5 is out of the allowable use set temperature range. Whether or not the temperature detected by the temperature sensor 5 is actually outside the allowable use temperature range can be determined.

(4) In the above embodiment, the holding portion 3 is held in a state in which the extended wall portion 3b covers the rear surface portion of the mobile terminal 2. Instead of this, an opening may be provided at the center of the extending wall 3b, etc., so that the conditioned air that is ventilated into the vehicle can be easily applied to the rear surface of the portable terminal 2 or the like. Moreover, about the shape of the holding | maintenance part 3, the attitude | position which hold | maintains the portable terminal 2, etc. can be changed suitably.

(5) In the above embodiment, the temperature sensor 5 is installed at the upper part of the flange 3c in the holding unit 3 with respect to the installation position of the temperature sensor 5. Instead of this, the temperature sensor 5 can also be installed in other parts that are exposed to direct sunlight, such as the back surface of the extending wall 3b in the holding unit 3.

(6) In the above embodiment, temperature detection by the temperature sensor 5 is always performed. Instead of this, as indicated by a dotted line in FIG. 2, temperature detection control means 13 that controls the start and stop of temperature detection by the temperature sensor 5 is provided, and temperature detection by the temperature sensor 5 can be performed intermittently. . This temperature detection control means 13 stops temperature detection by the temperature sensor 5 when the portable terminal 2 is not held in the holding unit 3 and detects that the portable terminal 2 is held in the holding unit 3. The temperature detection by the temperature sensor 5 is started. Thereby, only when the portable terminal 2 is held by the holding unit 3, the temperature is detected by supplying power to the temperature sensor 5 or the like, and wasteful power consumption can be suppressed to save power.

  Here, the detection that the portable terminal 2 is held in the holding unit 3 can be performed by, for example, detecting that the power supply to the portable terminal 2 is started by the charging unit 4. And if the portable terminal 2 is removed from the holding | maintenance part 3, since the electric power feeding to the portable terminal 2 by the charging means 4 will be stopped, the temperature detection by the temperature sensor 5 will be stopped by detecting the electric power supply stop. Can do. Further, for example, a switch that is turned on when the portable terminal 2 is inserted into the base portion 3a of the holding unit 3 is provided, and the portable unit 2 can be connected to the holding unit 3 by detecting that the switch is turned on. 2 can be detected. In this case, the temperature detection by the temperature sensor 5 can be stopped by detecting that the portable terminal 2 is removed from the holding unit 3 and the switch is turned OFF.

  The present invention includes a holding unit that is installed in a vehicle and can hold a portable terminal, and prevents the occurrence of problems such as failure of the portable terminal due to the ambient temperature of the portable terminal being out of the temperature range suitable for use of the portable terminal. However, the present invention can be applied to various portable terminal holders that can appropriately use the portable terminal in the vehicle.
