Abstract
The invention discloses a name card holder capable of displaying the amount of name cards used. The name card holder comprises a holder cover and a bottom holder, wherein a pressure sensor and a circuit board are arranged on the bottom of the bottom holder, a signal amplifier circuit, a single chip, a display driving circuit and a power module are arranged on the circuit board, the pressure sensor is arranged above the circuit board, the pressure sensor, the signal amplifier circuit, the single chip and the display driving circuit are orderly connected one after another, the power module is connected with the signal amplifier circuit, the single chip and the display driving circuit to provide power supply voltage thereto, respectively, an LED (Light Emitting Diode) display module for displaying the amount of the name cards used is arranged on the holder cover, and the LED display module is connected with the display driving circuit. The name card holder has the advantages that the function and the decoration effect of the name card holder are greatly enhanced, and even though a non-transparent name card holder is used, the number of the name cards in the name card holder can be still known, and therefore, when only a few name cards are left, the name cards can be added immediately and the embarrassment of insufficient name cards is avoided.
Description
Technical field
The present invention relates to a kind of card holder.
Background technology
Along with the level of people's life is more and more higher, for the also more and more polynary change of requirement of various traditional articles for use, along with the development of electronic applications, people also improve constantly for the demand of electronic product, and existing card holder only has the effect of depositing business card, its function singleness conventionally, at present general card holder is to adopt transparent material to be made on the market, the consumption that can see the inside business card by transparent shell, in the time that business card amount is few, can supplement business card in time.But in order to allow card holder look more high-grade, also a lot of opaque card holders have been there are at present, the for example card holder of corium shell, can not see by shell the business card quantity of the inside, can not see in time the quantity of the inside business card, in the time that needs are used business card, just find that card holder the inside business card quantity is inadequate, there is awkward situation.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of card holder that shows business card consumption that can see at any time the inside business card quantity.
The present invention solves the technical scheme that its problem adopts:
A kind of card holder that shows business card consumption, comprise box lid and bottom box, the bottom of box of the described end is provided with pressure sensor and the wiring board for responding to business card weight in card holder, on described wiring board, be provided with signal amplification circuit, single-chip microcomputer, display driver circuit and power module, described pressure sensor is arranged at the top of wiring board, pressure sensor, signal amplification circuit, single-chip microcomputer is connected successively in succession with display driver circuit, described power module respectively with signal amplification circuit, single-chip microcomputer is connected supply voltage is provided with display driver circuit, on described lid, be provided with the LED display module for showing business card consumption, described LED display module is connected with display driver circuit.
Further, on described wiring board, be provided with multiple pressure sensors.Be provided with multiple pressure sensors, can make its accuracy of detection higher.
Further, on described pressure sensor, be provided with the dividing plate for placing business card.Dividing plate is set on pressure sensor, can makes the pressure distribution of business card more even, measurement data is more accurate.
Further, on described box lid and bottom box, on corresponding position, be respectively arranged with lid contact interface and end box contact interface, described lid contact interface is connected with LED display module and display driver circuit respectively with end box contact interface.When closing after lid, lid contact interface and end box contact interface are in contact with one another, display driver circuit is connected LED display module by end box contact interface with lid contact interface and drives demonstration, after opening the lid, lid contact interface separates with end box contact interface, LED display module stops showing, after this design can realize and open card holder, LED display module is closed automatically, can effectively save electricity consumption.
The invention has the beneficial effects as follows: a kind of card holder that shows business card consumption that the present invention adopts, detect by the pressure sensor being arranged on the end box weight that is placed on business card in box, the check weighing data that pressure sensor detects transfer in single-chip microcomputer after amplifying processing by signal amplification circuit, described single-chip microcomputer passes through the consumption of business card in the real-time display name film magazine of display driver circuit driving LED display module according to detected data, the present invention has not only strengthened function and the decorative effect of card holder greatly, even if use opaque card holder, still can know the quantity of business card in card holder, in the time that business card quantity is few, can supplement in time business card, there will not be the awkward situation of business card quantity not sufficient.
