By transferring heat through the first thermal sheet 21, the temperature of the back side of the smartphone 10 and the comb-shaped heat radiating portion of the base 20 become substantially the same. Since heat can be efficiently dissipated from the heat radiating portion on the comb shape having a large surface area, it is possible to suppress the temperature rise of the smartphone 10. For example, a smartphone 10 that operates only when the outside air temperature is 40 ° C. or lower when heat is not dissipated can operate even if the vehicle interior temperature is about 60 ° C. by efficiently dissipating heat.

When the smartphone 10 is fixed to the fixing stand, the smartphone 10 is surrounded by the first thermal sheet 21, the second thermal sheet 31, the third thermal sheet 32, and the fourth thermal sheet 33 on the base 20. It is fixed. Therefore, even if the smartphone 10 is continuously vibrated for a long time while the car is running, the vibration and shock are absorbed by each thermal sheet, so that the vibration and shock applied to the smartphone 10 are greatly reduced. There is. Smartphones and the like are supposed to be carried by hand, and may not be designed to be continuously vibrated for a long time. However, by absorbing the vibration with each thermal sheet and reducing the vibration to the same level as when carrying it by hand, it is possible to maintain reliability and operate stably even when the smartphone 10 is used in a vehicle.

Next, heat dissipation from the smartphone 10 will be described. When the smartphone 10 is fixed to the fixing stand, the back side having the largest amount of heat generation is fixed to the flat side of the heat sink 62 via the rear side thermal sheet 63. The heat generated from the smartphone 10 is transferred to the heat sink 62 having the comb-shaped heat radiating portion via the rear side thermal sheet 63.

By transferring heat through the rear thermal sheet 63, the temperature of the back side of the smartphone 10 and the comb-shaped heat radiating portion of the heat sink 62 become substantially the same. Since heat can be efficiently dissipated from the heat radiating portion on the comb shape having a large surface area, it is possible to suppress the temperature rise of the smartphone 10. For example, a smartphone 10 that operates only up to an outside air temperature of 40 ° C. can operate even if the vehicle interior temperature is about 60 ° C. by efficiently dissipating heat.

Further, when the smartphone 10 is fixed to the fixing stand, it is fixed inside the front cover member 41 and the rear cover member 42 in a state of being surrounded by the front side thermal seat 52 and the rear side thermal seat 63. .. Therefore, even if vibration is continuously applied to the smartphone 10 for a long time while the vehicle is running, the vibration is absorbed by the front side thermal seat 52 and the rear side thermal seat 63, so that the vibration applied to the smartphone 10 is not included. It has been greatly reduced. Smartphones and the like are supposed to be carried by hand, and may not be designed to be continuously vibrated for a long time. In the fixing stand of the present embodiment, the front side thermal seat 52 and the rear side thermal seat 63 can absorb the vibration and reduce the vibration to the same level as when carrying it by hand. Therefore, by using the fixing stand of the present embodiment, it is possible to maintain reliability and operate stably even when the smartphone 10 is used in a vehicle.

Further, when the smartphone 10 is fixed to the fixing stand, the connector exists inside the convex portion 71 of the front cover member 41 and the convex portion 72 of the rear cover member 42, and only the USB cable 11 is from the groove portion. It is pulled out. Therefore, even if the USB cable 11 is pulled, the connector portion of the USB cable 11 is unlikely to come off from the smartphone 10. Therefore, it is possible to prevent the USB cable 11 from coming off from the smartphone 10 due to vibration even when mounted on a vehicle.

The USB cable 11 and the smartphone 10 having different natural frequencies may vibrate in different directions due to the vibration in the vehicle. If such a state continues for a long time, the connector may be damaged and poor contact may occur. In particular, the Micro USB connector, which is small and has low strength, is easily affected by vibration. However, in the present embodiment, since the connector is sandwiched between the front cover member 41 and the convex portion of the rear cover member 42, the USB cable 11 and the smartphone 10 vibrate in the same direction and size. Therefore, the connector is less likely to be damaged, and reliability can be ensured even when mounted on a vehicle.

In the fixing stand of the present embodiment, the heat generated from the smartphone 10 can be efficiently dissipated by the rear side thermal sheet 63 and the heat sink 62 on the back side of the smartphone 10. Therefore, the fixing stand of the present embodiment can suppress the temperature rise of the smartphone 10 even in an environment where the ambient temperature is high. Therefore, by using the fixing stand of the present embodiment, the smartphone 10 can be operated stably even in an environment where the ambient temperature is high.

The fixing stand of the present embodiment includes a front side thermal seat 52 and a rear side thermal seat 63 around the smartphone 10 and on the back side. Therefore, since the fixing stand of the present embodiment can absorb the vibration and the shock applied to the smartphone 10, the information terminal device can be used without deteriorating the reliability even in an environment where the vibration and the shock are continuously applied. Can be operated.

From the above, the fixing stand of the present embodiment can stably use an information terminal device such as a smartphone 10 without degrading the reliability due to a defect in the connection portion of the USB cable or the environment in which it is used.

By increasing the number of arms, the smartphone can be held more stably. Further, the upper side of the smartphone may be held by a rectangular portion longer than the width of the arm along the upper side of the smartphone attached to the arm. By holding the upper side of the smartphone at a rectangular-shaped part that is longer than the width of the arm, the smartphone can be held more stably. In particular, in the case of a configuration in which the display screen of the smartphone can be rotated by rotating the base, the effect of stably holding the smartphone becomes remarkable.

In the fixing stand of the second embodiment, the upper side of the smartphone is held by the arm, but a tapered member may be used to hold both ends of the upper side of the smartphone. That is, the four corners of the smartphone may be held by a tapered member. In such a configuration, for example, a fixing stand is provided with an arm that slides in the vertical direction near the center, and elastic materials are formed on the downward surface at both ends of the beam extending in the horizontal direction. It can be configured to include a tapered member. By holding the smartphone at two places on both ends on the upper side as well, the smartphone can be held at the four corners, so that the smartphone can be more stably fixed to the fixing stand. Further, the tapered members that hold the upper side may be provided on independent arms.

Further, in any of the above configurations, the target to be fixed to the fixing stand may be an information processing device other than a smartphone.
