Description

  The present invention relates to a mouse pad equipped with a DC uninterruptible power supply, and more particularly to a mouse pad equipped with a function of a mobile DC uninterruptible power supply. The present invention relates to a mouse pad that can be activated to supply power to a product to be combined and extend the working time by using the power of the product to be combined as an uninterruptible power source.

  A commonly known mouse pad is used to slide a mouse thereon, and has no other function. In addition, products such as an uninterruptible power supply system and a power supply only have a single function, and consumers must purchase the corresponding product in order to use the function, and the system weight and volume are reduced. And it is inconvenient to carry and does not meet the demands of travelers.

  The present invention has been made in view of the above-mentioned drawbacks of the background art, and provides a mouse pad having a type of DC uninterruptible power supply which has improved the drawback.

  Therefore, an object of the present invention is to provide a mouse pad equipped with a kind of DC uninterruptible power supply. When combined with a product such as a panel computer, and the commercial power supply is in a completely normal power supply state, the AC / DC power conversion / supply unit charges the battery inside the mouse pad, and supplies power to the combined product. In response to the request, when the commercial power supply stops supplying power, the mouse pad immediately drives the internal battery to respond to the power request of the combined product, and the combined product provides the power uninterruptibility function and its own Provides a function to extend working time.

The invention of claim 1 comprises a battery charging circuit, a detecting circuit, a boosting circuit, and a rechargeable battery, an AC / DC power conversion / supply device is externally connected, a product to be combined is connected to the other end, and a commercial power supply is supplied with a normal power supply. In this state, the AC / DC power supply / recharger charges the battery inside the mouse pad, and supplies power to the combined product. When commercial power fails, the mouse pad immediately starts up the internal battery and combines it. A mouse pad provided with a DC uninterruptible power supply, characterized in that it is formed to supply power to a product to be manufactured.
According to a second aspect of the present invention, there is provided a mouse pad provided with the DC uninterruptible power supply according to the first aspect, wherein a voltage stabilization control charging circuit is provided inside the battery charging circuit. It is a mouse pad with a feeder.
According to a third aspect of the present invention, there is provided a mouse pad including the DC uninterruptible power supply according to the first aspect, wherein a battery charging over-pressure over-current detecting circuit, a battery capacity detecting / voltage stabilizing and displaying circuit and a switch are provided inside the detecting circuit. A mouse pad provided with a DC uninterruptible power supply, wherein a circuit driver is provided.
According to a fourth aspect of the present invention, there is provided a mouse pad including the DC uninterruptible power supply according to the first aspect, wherein a control circuit is provided inside the booster circuit. Has a mouse pad.
According to a fifth aspect of the present invention, in the mouse pad provided with the DC uninterruptible power supply according to the first aspect, a product to be combined is a notebook computer or a flat panel computer. It is a mouse pad with a feeder.

  The mouse pad equipped with a DC uninterruptible power supply of the present invention is a mouse pad equipped with a movable DC uninterruptible power supply, and a device that uses a battery such as a notebook computer or a flat panel computer as a power supply. In addition, products that are used in equipment or any products of the same demand and that use DC power as a power supply can be continuously used without a commercial power supply or in a power failure state. Its practicality is clear, and the structure of the present invention is not described in publications distributed before the filing of the application and is not used in public, and therefore has novelty.

  As shown in FIG. 1, a battery charging circuit 11, a detection circuit 12, a boosting circuit 13, and a rechargeable battery 14 are provided in the mouse pad 1 of the present invention. One end of the mouse pad 1 is externally connected to an AC / DC power supply / supply device 2 and the other end is a product 3 to be combined, such as a notebook computer, a flat panel computer, or other equipment that receives DC power supply, a meter or the like. The product is connected. When the commercial power supply 4 is in a completely normal power supply state, the externally connected AC / DC power supply 2 charges the battery inside the mouse pad 1 and responds to the power demand of the product 3 to be combined. I do. When the commercial power supply 4 stops supplying power, the mouse pad 1 immediately activates the internal rechargeable battery 14 to respond to the power requirement of the product 3 to be combined, thereby providing uninterruptible power supply to the product 3 to be combined. Provide a function to extend working time.

  The detailed structure of the above-mentioned mouse pad 1 is as shown in FIG. 2. The voltage stabilization control charging circuit 111 is provided inside the battery charging circuit 11, and the DC voltage 21 input from the AC / DC power conversion / supply unit 2 is supplied to The output is a battery charging voltage output 112 via the battery charging circuit 11.
