The main body framework of portable machine ark uses ABS data, reason weight is lighter. In the meantime, the design construction that machine ark joined portable sex (handle) , raised the removability of machine ark effectively. The machine ark of this form suits on certain level in small-sized carry a car the requirement with compositive hardware of system of aspirant travel information. But because integral volume is larger, its application still gets very big limitation. 2.

The uses box of portable electron equipment to break ark of machine of 19 inches of levels measure of box of equipment of 2 portable electrons is restricted, adopt suit to be inside the car more (especially small-sized car) the dimension of installation and configuration. Its introduce the idea of combined-type casing, every casing is a relatively independent module, a module is compositive the car carries lash-up to lead communication system a certain number of independent function, a certain number of module combination forms whole vehicle to carry lash-up to lead communication system together. Use modular thought to reach an electron to equipment yuan parts of an apparatus undertakes assorted, realize the layout design of optimization, the dimensional utilization rate that can raise box greatly and equipment are compositive degree. The structural sketch map of box of portable electron equipment is shown 3 times like the graph. 3.

If the graph is shown 4 times,box of portable electron equipment designs the three-dimensional structure of box of portable electron equipment, its over all dimension is 600mm (L) × 420mm (W) × 140mm (H) , casing material is given priority to with aluminous material. Additional, in box two side were designed carry handle. This over all dimension and material and the design that carry handle can increase the portable sex of box greatly. Before design of box of portable electron equipment has, hind transfer face plate. Interface of machine of face plate humanness transfers before board, the man-machine that finish is operated and indicate a function. Face plate transfers to be equipment interface after board, between the box that finish, the join between box and peripheral. Additional, design of interior of box of portable electron equipment has installation scaleboard, the equipment inside box or yuan parts of an apparatus all is installed go up in installation scaleboard. When the equipment inside box is changed, need to change around to transfer only board with installation scaleboard can, can assure the versatility of structure of box main body thereby. Design of around of box of portable electron equipment has retroflexion cover board, use at protecting around to transfer face plate. Retroflexion cover board is buckled through the bedspring card of the design undertake locking, and around retroflexions cover board is dismountable. Two side design has box of portable electron equipment join lock, box top design has fixed position piece. An overlay of fixed position piece supports to place through box between box, undertake join locking through lock. Hind installation has box of portable electron equipment medicinal powder sirocco fan, every side design has box two airway; The distributinging circumstance of heat source of the facility inside box of the basis when using is reasonable install airway, in order to form specific circular air channel, realize box interior equipment and parts of an apparatus medicinal powder hot. 4.

The box of portable electron equipment of article design applies the applied example of box of portable electron equipment successfully already at the small-sized 3G graph of some project to send communication command car, the main function of this command car is to realize shortwave, ultrashort communication and 3G graph to conduct a function. The hardware that sends communication command car in small-sized 3G graph is compositive go up, will whole system differentiates for two module: Distribution module and communication module. Distribution module is in charge of offerring distribution for whole communication command system; Communication module is in charge of realizing shortwave communication function, ultrashort communication function and 3G graph to conduct a function. If the graph is shown 5 times,the objective of distribution module, communication module pursues, the combination of distribution module and communication module is shown 6 times like the graph. 5.

The characteristic 　 of box of portable electron equipment 5.
