DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chassis for electronic equipment which is mounted on an automobile or the like and which can operate in a moving state.

[0002]

2. Description of the Related Art In emergency vehicles such as ambulances, military vehicles, and the like, it is required that electronic devices be mounted on automobiles and the like so that they can operate in a moving state. Particularly in recent years, it has been required to mount electronic devices such as personal computers and printers which could not be mounted conventionally.

FIGS. 8 to 12 show an electronic device chassis accommodating a personal computer for the above purpose. The electronic device chassis 100 is formed of a drawer-type housing, and two rails 101 extending from a rack fixed inside an automobile or the like are fixed to both side plates 102, 102 and are slidable.

[0004] Both side plates 10 of the electronic equipment chassis 100
Air inlets 103, 103 are formed on the front side of 2, 102, and a fan 105 is mounted on the back plate 104. Further, rack mounting screws 107 are provided at four corners of the front plate 106 of the electronic device chassis 100.

[0005] A personal computer 200 is housed and fixed inside the electronic equipment chassis 100.
An intake port 201 is formed on the front surface of the case of the personal computer 200, and a fan 203
Is attached.

Further, a heater 111 and a fan 112 for agitating warm air are arranged in a space inside the electronic device chassis 100 where the personal computer 200 is not provided.

In the above configuration, when the power of the personal computer 200 is turned on, the fans 203 and 105 are operated to release the heat inside the housing of the personal computer 200 to the outside.

[0008]

On the other hand, the heater 111 and the fan 112 for stirring warm air are turned on when the temperature falls below the guaranteed temperature of the personal computer 200 by a thermostat or the like (not shown). At times, all the fans 203, 105, 112 are in operation. That is, when the temperature is lower than the guaranteed temperature of the personal computer 200, the flow of air in the electronic device chassis 100 is as shown by the arrow X in FIG. 9, and most of the air heated by the heater 111 is There is a problem that the heat is emitted from the fan 105 to the outside without entering the housing of the personal computer 200, resulting in poor efficiency.

When the electronic device chassis 100 is returned to the rack by sliding the rails 101, 101,
Rack mounting screws 107 at four corners of the front plate 106 are screwed into the rack. For this reason, the front plate 106 side of the electronic device chassis 100 does not relatively vibrate, but the rail 101,
Since 101 is only fixed to the side plate 102 at one point, the rear plate 104 vibrates in the vertical direction indicated by the arrow Y in FIG. 11 and the operation of the personal computer 200 becomes unstable. In the worst case, It broke down.

In addition to the personal computer 200, it is considered that a printer 50 shown in FIG. 12 is mounted on an automobile or the like and operated in a moving state. However, the printer 50 is used to the extent that it is fixed directly to the floor of the vehicle or to a rack fixed inside the vehicle using bolts and nuts, etc., and measures to prevent vibration of the vehicle from being transmitted and operation. No countermeasures were taken when the temperature dropped or rose below the guaranteed temperature.
