Referring to fig. 1 to 6, an embodiment of the present invention provides a computer interface expansion device.

The computer interface expansion device consists of a shell 1, a joint 2, an interface, a control chip and a fixed structure. The control chip is fixedly arranged inside the shell 1, electrically connected with the joint 2, electrically connected with the interface, fixedly arranged on the surface of the shell 1, and provided with a fixing structure. The control chip is a circuit board with a microprocessor, and the control chip is fixed inside the shell 1 through a plurality of small screws. The screw is firmly fixed and connected, the stability is good, and the control chip is not easy to loosen even if the control chip is frequently shaken and shaken.

The connector 2 is connected with the control chip through a cable, and the connector 2 is used for being connected with a portable ruggedized computer. The connector 2 can be a USB connector, and the USB connector is plugged into a corresponding USB socket on a computer when in use. The interface and the control chip are connected through a cable and fixed on the surface of the shell 1. The interface is used for connecting external devices (such as a projector, a printer, audio equipment and the like), and when the interface is used, a plug of the external equipment is inserted into the interface to be communicated.

The housing 1 is also provided with a fixing structure (e.g. adhesive) on the surface, by which the computer interface expansion device can be firmly fixed to the back of the portable ruggedized computer or other suitable position.

When the computer interface expansion device connector 2 is installed, the computer interface expansion device connector is inserted into a corresponding socket of a computer. The housing 1 is then securely held in place by a securing structure that is moved to the rear of the portable ruggedized computer, or other suitable location. The problem that the traditional interface expansion device cannot be fixed with a portable reinforced computer is solved, and the embarrassing situation that the interface expansion device is easy to lose or forget to carry is avoided.

When in use, the plug of the external equipment is inserted into the interface of the computer interface expansion device, and the computer interface expansion device can be communicated for use. The control chip can process the signals. The connector 2 is provided with one, and the interface can be provided with a plurality of connectors. One connector 2 is electrically connected with the portable ruggedized computer, and a plurality of interfaces can be inserted into plugs of a plurality of external devices, so that the multifunctional expansion is met. And under the control chip's additional support, the interface can set up different kinds of interfaces, for example Type-C interface, audio interface, VGA interface and the interface that other special equipment customization were held. The computer interface expansion device of the embodiment solves the problems that the external connection interface of the portable reinforced computer is insufficient and special interfaces cannot be provided, can provide more interfaces for connecting external equipment, and can provide some special interfaces for connecting the external equipment.

In some embodiments of the present invention, the computer interface expansion device further includes a dustproof structure, as shown in fig. 2 and 3. The dustproof structure comprises a dustproof cover 3, the dustproof cover 3 covers the surface of the shell 1 and is fixedly connected with the shell 1, the fixed connection can be selected in an adhesion mode, and the shell 1 and the dustproof cover 3 are bonded together through strong glue. An opening 31 is opened on the surface of the dust cover 3, and the shape and the position of the opening 31 correspond to the shape and the position of the interface. The opening 31 is provided to facilitate the insertion of a plug of an external device into the dust cover 3 and into the interface. Because the portable ruggedized computer usually works in some places with bad conditions, and the surface of the shell 1 with the interface is covered by the dust cover 3, the interface can be prevented from being directly invaded by dust, sand wind and splashed water, a certain protection effect is achieved, and the service life of the computer interface expansion device is prolonged.

In some embodiments of the present invention, as shown in fig. 4 and 5, the dust cover 3 further includes a connection post 32, a dust-proof plate 33, and a torsion spring 34.

When the dust-proof plate is installed, the connecting column 32 is connected with the dust-proof plate 33, and then the two ends of the connecting column 32 are bonded on the side wall of the opening 31. The size of the dust-proof plate 33 corresponds to that of the opening 31, and the dust-proof plate 33 just covers the opening 31. In order to avoid the dust-proof plate 33 from being restricted by the side wall of the opening 31 when rotating, the side surface of the dust-proof plate 33, which is close to the connecting column 32 and is parallel to the connecting column 32, is set to be a cambered surface.

The torsion spring 34 is composed of a torsion spring main body 341, a first torsion spring leg 342, and a second torsion spring leg 343. The torsion spring body 341 is disposed inside the dust cover 3 and contacts the inner wall. The first torsion spring leg 342 is fixed to the inner wall of the dust cover 33, and the second torsion spring leg 343 passes under the connecting post 32 to contact the dust cover 33.
