Abstract
The utility model relates to an electronic top with functions like rotation circle number counting display. A circuit comprising a control chip, a geomagnetic sensor, an LBD, a battery, keys, resistors and capacitors is arranged inside the case of the top. The control chip measures and reflects the signals from to the geomagnetic sensor to decide whether the top turns a circle or not, and dynamic displays the result of the measurement on the LBD using the persistence of vision phenomenon. Different functions can be chosen via the keys. The utility model can be used in many ways interesting and competitive.
Description
Affiliated technical field
The utility model relates to a kind of toy top, particularly relates to a kind of electronic gyroscope toy that shows numeral, character, graphing capability that has.
Background technology
In the existing toy top, can be divided into two big classes substantially on function: a class is traditional.This toy top only has spinfunction, and its variation is mainly reflected in aspects such as profile, type of drive.The shortcoming of this gyro is to lack interest.Another kind of is electronic electronic gyroscope.In traditional toy top, increased electronic or electronic section, toy top has not only had spinfunction, but can also be sound in rotation, the variation of light, it is with respect to traditional gyro, interest strengthens greatly, because light is arranged, also can use simultaneously in night.Yet, in existing toy top that can be luminous, though can be luminous when gyro rotates, also only limit to light at random or flicker according to certain rules, there is no any practical significance.
Summary of the invention
The purpose of this utility model provides a kind of electronic gyroscope, and it possesses multiple function, its when rotated: (1) can show the number of turns of gyro rotation in real time; (2) show the time that gyro rotates in real time; (3) has compass functional; (4) write down and show maximum rotating cycle; (5) record and the longest rotational time of demonstration; (6) show given character string; (7) show given figure etc.
The technical scheme that its technical problem that solves the utility model adopts is: in the gyro enclosure interior one circuit board is arranged.Devices such as control chip, geomagnetic sensor, battery, light emitting diode, key switch and resistance, electric capacity are installed on the circuit board.Control chip is as core devices, and it knows selected function from key switch on the one hand, and detects the anglec of rotation or do not revolve by the output signal that receives geomagnetic sensor and make a circle; On the other hand, control chip drives eight or seven light emitting diodes simultaneously, as showing numeral, character or figure usefulness.Eight or seven light emitting diodes are arranged in a straight line on warp.In order to use eight or seven light emitting diodes to show character, numeral or figure, the utility model adopts the mode of lattice scanning output, and light emitting diode is lighted in timesharing, utilizes persistence of vision phenomenon, thereby finishes the demonstration of functions such as numeral, character, figure.
The utility model has the advantages that: integrate interesting, recreational and practicality.Both can recreate by oneself, also can many people match unexpectedly; Both can use daytime, also can use night; Existing amusement function can be taken one's bearings again.It is a all-ages toy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment profile of electronic gyroscope.
Fig. 2 is circuit theory diagrams of the present utility model.
Fig. 3 is an embodiment circuit board component of electronic gyroscope face figure.
Fig. 1 is the elevation cross-sectional view of an embodiment of the utility model.Electronic gyroscope is by last cover (1), down cover (2) and the circuit that is installed in the components and parts formation above the circuit board (4) are formed.Circuit board is fixed on down on the cover by screw (5).Light emitting diode (3) is fixing by support (6), and the head of light emitting diode just in time passes a round that covers, and makes the light that outside visible light emitting diode (VLED) sends.Owing to be cutaway view, make subelement invisible.Among Fig. 1, (7) are buttons, and (8) are 3 volts of button cells, and (9) are resistance, and (10) are control chips.
Among Fig. 2, U1 is a control chip, and ES is a geomagnetic sensor, and LD1-LD7 is a light emitting diode, and R1-R7 is a current-limiting resistance, and C1, C2 are power filtering capacitor, and R9, R10 are pull-up resistor, and K1 is a function key, and K2 is an acknowledgement key, and C3, C4 are for removing to shake electric capacity, and XT is a crystal oscillator.
The specific embodiment
Among Fig. 2,, select corresponding function at first by function key.Every a kind of function of representative of seven light emitting diodes is whenever pressed primary key, and indicator lamp is lighted to the LD1 circulation to LD7 by LD1 successively again, presses the K2 key then for confirming this function.After choosing function, control chip begins image data from geomagnetic sensor.Geomagnetic sensor is a three terminal device, be respectively power supply, and output.The output of geomagnetic sensor reflects the angle changing in earth's magnetic field in the mode of frequency change.The power supply of geomagnetic sensor is provided by control chip, so that economize on electricity.Control chip passes through to gather the geomagnetic sensor signal, thereby calculates the angle of rotation, and and judges whether thus to make a circle.Control chip can be realized compass functional according to the detection of angle; And the number of turns numeration to turning over then can realize the detection of real-time rotating cycle.Equally, if within a certain period of time, the signal that collects does not change or variation is very little can judge that then gyro stops the rotation, thereby realizes clocking function.The data that at every turn obtain are compared and keep maximum, then can finish the maximum number of turns of rotation and maximum duration function.By seven light emitting diodes, final result is shown.In order to use seven light emitting diodes to show character, numeral or figure, the utility model adopts the mode of lattice scanning output, just the character that will show, numeral or figure, take advantage of the dot matrix of 7 row to describe with 5 row, light row at every turn, divide and finish a complete dot matrix demonstration for 5 times, made full use of people's persistence of vision phenomenon, thereby looked like complete numeral, character or a figure.
Fig. 3 is the circuit board component face picture of an embodiment of electronic gyroscope.Shown the putting position of 7 light emitting diodes among the figure, promptly be placed on the ray that sets out with central point.Fig. 3 also adds and understands the position of not indicating element among Fig. 1 in addition.
