1. FIELD OF THE INVENTION
This invention is in the field of support racks for electronics, specifically for mounting communications equipment inside a portable case.
2. BACKGROUND OF THE INVENTION
Military operations require an extensive amount of advanced electronics for communications, monitoring, data processing, and more. These electronic components are typically housed in a trailer or bunker called a command-and-control (or “C2”) module. The present invention provides a command-and-control module in a portable housing the size of a suitcase. There are numerous obvious advantages to downsizing a command-and-control module to a portable unit. Challenges to this portability include climate control, shock absorbency, secure attachment, connectivity, and ease of interchangeability. The present invention provides improved solutions to these challenges.
3. DESCRIPTION OF RELATED TECHNOLOGY
The current generation of portable command-and-control modules is exemplified by models such as General Dynamics' Small Form Factor C2 node™. This system is housed in a front-opening case. Inside the case, electronics are bolted to a framework of horizontal and vertical racks, which are in turn bolted to the inside of the case. The interior of the case is cooled with standard convective computer fans.
An alternative embodiment is represented by the Next Computing™ line of “portable workstations”. Models such as the Vigor™ provide an open-ended case with a fixed chassis that has multiple expansion slots for electronic racks. Other models simply provide a case with a “foam cutout” in which to position and carry electronic components.
4. SUMMARY OF THE INVENTION
The present invention is a portable command-and-control module characterized by a removable chassis supported inside a top-opening case. The chassis assumes the form of a trough, with two vertical plates permanently affixed to a horizontal plate at the bottom. DIN (Deutsches Institut für Normung/trans. German Institute for Standardization) rails can be secured to the vertical plates. These DIN rails are the point of attachment for electronic components, using standard attachment tabs.
The interior of the case is cooled by a thermoelectric cooler.
The bottom of the case and the horizontal plate of the chassis are equipped with shock-absorbers.
The top of the chassis is secured with hand-turned bolts to an upper horizontal cover. The inner cover, ideally formed of a transparent plastic, protects the electronics from airborne particles when the case is opened. When the hand-turned bolts are removed, the entire chassis lifts quickly and easily out of the case. Horizontal handles connecting the tops of the vertical side plates enable human placement of the chassis in and out of the case. This allows for efficient interchangeability of the electronic components. For instance, depending on the context of the operation, it may be desirable to add a high-end encryptor or to swap a full memory card with a new one.

6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1 and 2 are perspective views of a chassis 1 used to support electronic equipment. The chassis has a front vertical plate 11, a rear vertical plate 12, and a horizontal plate 13 connected to the bottoms of the front and rear vertical plates. In a best mode, the plates 11, 12, and 13 are metallic and welded together. Front and rear upper rails, 15 and 16 respectively, are secured to the tops of the front and rear vertical plates, respectively. At least one handle 14 is situated at the top of the chassis, spanning from a front vertical plate or upper rail to a rear vertical plate or upper rail.
In a preferred embodiment, the chassis may support at least one DIN rail. DIN rails are commonly used to support electronic components in factories. FIG. 2 shows a DIN rail 17 secured to the front vertical plate 11.
In FIG. 3, the chassis 1 supports electrical and electronic equipment 3 mounted on two DIN rails 17, one on the front vertical rail 11 and the other on the rear vertical rail 12. In a preferred embodiment, the electrical and electronic equipment 3 comprises a low side (unencrypted) switch 31, a low side router 32, a high side (encrypted) switch 33, a high side router 34, power supplies 35, and ancillary electrical equipment 37, which may include power distribution hardware, a thermostat, and a surge protector. Typical power supplies would include 12, 24, and/or 48 V supplies for the routers and switches and a cooling device.
FIG. 3 also shows chassis-mounted shock absorbers 131 secured to the corners of the horizontal plate 13. The shock absorbers protect the electronic equipment from mechanical impact to the chassis or its case.
It is helpful to have added capability for an encryptor 36, as seen in FIG. 4. Since it is desirable to have quick and easy access to the encryptor, e.g. to insert or remove it from the chassis, it is practical to mount the encryptor to a removable vertical plate 18, which can be secured to the front or rear vertical plate of the chassis.
In best practice, the chassis is protected within a case 2, shown in FIG. 4. The case provides portability and protection from the environment. In a preferred embodiment, it includes a cooling device, ideally a thermoelectric cooler (TEC) 23. A TEC transfers heat without refrigerant lines, making it lightweight and practical for a small, enclosed space like the case. Nor does it rely on ambient air for convective cooling, which is important when the atmosphere is hot and/or polluted. The case also includes electrical outlets and ports 38 so that the electrical and electronic equipment 3 may be plugged into peripheral devices and power supplies.
FIG. 5 shows the interior of the case 2, with a clear view of the TEC 23 and the electrical outlets and ports 38. The interior of the case may have case-mounted shock absorbers 21 as further protection against mechanical shock.
FIG. 6 presents an alternative view of the case 2 containing the chassis 1, which supports electrical and electronic equipment. An inner cover 22 (which may be fabricated of a transparent plastic) protects the underlying equipment from atmospheric particles. The inner cover 22 is secured to the front and rear upper rails 15 and 16, for example with inner cover bolts 221. The inner cover also makes a suitable mount for an antenna 222, which is used to convey signals between the routers and outside communication devices such as satellites, cell phone towers, or other command-and-control modules.
FIG. 7 illustrates the process of inserting the chassis 1 into the case 2, or similarly removing the chassis from the case. After removal of the inner cover bolts 221, the inner cover 22 can be lifted to access the chassis and electronics below. The antenna 222 functions as a handle or grip for the inner cover.
FIG. 8 presents a closer look at the removable vertical plate 18. As shown, it is being positioned adjacent to the rear vertical plate 12. Tabs 181 at the bottom of the removable vertical plate may be placed into slots 132 along the edge of the horizontal plate 13. The removable vertical plate may then be secured to the rear vertical plate 12, e.g. with bolts.
The case 2 is seen closed in FIG. 9. It is equipped with a handle and wheels for easy transport. The electrical outlets and ports 38 ideally include a QFoca fiber link and an outlet to a MIMO antenna.
