The present invention relates to the field of computer keyboards, and to a retractable computer keyboard with a hand-painted board and using method thereof.
Hand-painted boards and keyboards are important input peripheral for computers, the hand-painted boards are usually made up of a board and a pressured pen, which, to painting creator, just like the painter's easel and brush, this painting function of which is beyond comparable to the keyboard and the tablet, which is mainly suitable for designing, for teachers and students of fine art related, advertising agents and for design studios and for vector anime makers by Flash.
Referring to the Chinese patent application No. 201810080753.6-a retractable computer keyboard with hand-painted board discloses that which, comprising a computer keyboard body with a kickstand device, a keyboard body and a propping back plate, and the kickstand device includes a supporting leg, at which the rotating lever are arranged at one end of the support leg, and the supporting leg is mounted on the supporting leg by a rotating lever, and the other end of the support leg is provided with a pulley. As the device of this patent folds the hand-painted board and the keyboard together, it increases the overall thickness and occupies more space.
Retractable Computer Keyboard with Hand-Painted Board and Using Method Thereof of the present invention is disclosed to resolve the above problems for reducing the thickness of a retractable computer keyboard with a hand-painted board. Therefore, an innovative device is designed by utilizing a pneumatic-activating and automatic soft silicone keyboard to speed up the keyboard unfolding, and at the same time, a storage with coil spring spooling is provided for soft silicone keyboard, reducing the space occupancy and thickness of the soft silicone keyboard, and the hand-held pen is pinned into the placement slot of the underlying beam, which enable the overall structure is more compact.
The present invention achieves the above objects by the following technical solutions:
The patent of a retractable computer keyboard with a hand-painted board comprises a kickstand pad, a soft silicone keyboard and a coil spring strip; the kickstand pad is provided with a hand-painted screen, and one side of the hand-painted screen is provided with a telescopic switch, beneath of which is arranged a power indicator, inside the kickstand pad there is devised a circuit board with a MCU built-in, its type is C51; an air pump of model ASD-300DC is arranged on one side of the MCU and is provided with a tee pipe, beneath of which, the aerating tube is arranged; below the kickstand pad is arranged with a fixed groove with aeriferous orifices, below the fixed groove is provided with a soft keyboard with a button, below the button is arranged with a piezoelectric switch, beneath of which, is arranged a sachet of air storage; below the soft keyboard is arranged with a underlying beam with a placement slot, which is devised with a hand-drawn pen, one side of which, is devised with a finger crypt, on a bottom of the hand-drawn pen is arranged a semi-circular stylus; and the top of the underlying beam is arranged coil spring strip, in the middle of the back of the kickstand pad is arranged with a spooling slot with a spooling hook, to the upper of which, a USB cable is provided with, and a USB plug is devised on the USB cable, and above the spooling slot is provided a groove of wire inlaid, below which, a nameplate board is devised.
In this embodiment, a protective cover is provided and glued at the back of the soft silicone keyboard, whereby, the protective cover is used for fixed connecting the coil spring strip and the soft silicone keyboard, and the glue boost the connection strength of the protective sleeve, ensuring the soft silicone keyboard stable and reliable; the soft silicone keyboard is made of a soft rubber material, and is respectively glue upon the fixed groove and the underlying beam, whereby, the soft rubber material keeps the soft silicone keyboard furled. In this embodiment, the surface of the hand-drawn pen is provided with and glued a non-skid sleeve to increases the frictional force against the hand from sliding; a suction pad is arranged and glued at the back of the underlying beam, whereby, the suction pad is easily opened with robust durable life. In this embodiment, the coil spring strip is of spring steel material and is riveted at the underlying beam for guard of the bounce force of the coil spring strip and its strength; the corners of the back of the kickstand pad are provided with non-skid pads, which are connected to the kickstand pad by bolts for the stability of the kickstand in use, and the bolts make disassembling and replacing the non-skid pad much easier. In this embodiment, the USB cable is wound on the spooling hook, the height of which is less than the depth of the spooling slot in case of the kickstand pad being jacked up, and the USB plug is welded at the USB cable for its convenient opening and reliability; the MCU is electrically connected to respectively the telescopic switch, the power indicator, the hand-painted screen, the air pump and the piezoelectric switch for transmitting control signals.
In this embodiment, the specific usage method includes the following steps:
In comparison with the prior arts, the beneficial effects of the present invention are resulted as follows:
In order to clearly illustrate the embodiments of the present invention or the technical solutions of the prior arts, the accompanying drawings in the embodiments or in the description of the prior art will be briefed below. Obviously, the drawings in the following description are only confined to some embodiments of the present invention, and other drawings can be obtained from those skilled in the art without inventive labour.
