Description

Electronic digital display type ergograph

This utility model relates to the metering apparatus of power, the metering apparatus of human body dynamics such as a kind of power of boxing, grip, arm strength.

Existingly being used for measuring the human body dynamics, as the apparatus of boxing power, grip, arm strength, generally is mechanical.Mechanical type dynamics meter regulator tool measuring accuracy is low, unreliable, not directly perceived, especially can only adopt qualitative metering for the metering of boxing power, arm strength, can not show dynamics accurately, intuitively.

This utility model is intended to overcome the defective of mechanical type dynamics meter regulator tool, adopts the electronic digit display mode, provides a kind of and can reflect human body institute application of force degree accurately, intuitively, such as the metering apparatus of boxing power, grip, arm strength.

This utility model is beaer, pick off and the character display by different structure, and the conversion of signals that simulates of power is become the signal of telecommunication, by digital display circuit, reflects the dynamics of being executed on character display.The apparatus of this metering power is by support, beaer, pick off and digital display circuit are formed, pick off is made up of two resistance strain gages (ML) and flexible component (8), these two resistance strain gages (ML) are affixed on two sides of flexible component (8), beaer contacts with flexible component (8), power is put on the flexible component, make flexible component (8) distortion (as bending), be affixed on the also distortion thereupon of resistance strain gage (ML) on the flexible component (8), resistance changes, stressed big more, then change in resistance is terrible more, resistance strain gage and two resistance R 1, R2 forms the foil gauge bridge circuit, and the voltage signal of digital display circuit is provided.Digital display circuit comprises resistance strain gage bridge circuit, amplifying circuit, peak sampling hold circuit, A/D converter, display, peak detection circuit and power supply.Fig. 1 is the digital display circuit block diagram.Fig. 2 is embodiment digital display circuit figure.As shown in Figure 2, two resistance strain gages of strain gage bridge route (ML) and two resistance (R1, R2) are formed, amplifying circuit is amplifier A1, sampling hold circuit is made up of amplifier A2, A3, diode (D1, D2) and capacitance resistance component R5, R6, C etc., A/D converter adopts 7117 chips, peak detection circuit is made up of amplifier A4 and transistor T 1, display is a light-emitting diode display, can adopt three positive LED charactrons altogether, power supply can adopt bridge rectification power, supplies with each several part corresponding work voltage.The foil gauge bridge circuit connects output amplifier, the outfan of amplifying circuit connects the input of sampling hold circuit and peak detection circuit respectively, the outfan of sampling hold circuit connects A/D converter and peak detection circuit respectively, the output termination A/D converter of peak detection circuit, A/D converter output termination light-emitting diode display.After this force meter being used for public, the connection of controlling display circuit as the employing mode of inserting coins is whether the time, the present embodiment (see figure 2), a display power supply control circuit is provided, the R-S trigger that this power control circuit is made up of NAND gate G1, G2, diode D3, not gate G3, transistor T 2, relay J are formed, the contact of relay J connects the LED power end, R-S triggering signal input termination peak detection circuit.

The work process of digital display circuit is described below in conjunction with Fig. 2.After machine is connected civil power, power supply is given the each several part circuit supply, but because the display control circuit repeat circuit still is in release conditions, the display non-transformer is supplied with, and display does not work, after inserting coin, the K switch closure, the upset of R-S trigger, power control circuit repeat circuit J adhesive, display power supply is connected, display is bright, be shown as zero this moment, when extraneous masterpiece during in force transducer, makes the resistance strain gage distortion, the foil gauge bridge circuit will produce voltage signal, amplify through amplifier A1,, will simulate conversion of signals by A/D converter and become the digital signal driving display to show by peak sampling hold circuit.After external influence power peak value, peak holding circuit keeps peak voltage signal, at this moment after peak detection circuit measures peak value, just lock A/D converter, make that display peak value display number is constant, peak detection circuit makes the upset of R-S trigger simultaneously, behind the display power supply control circuit time-delay certain hour, close display power supply, one time dynamometry finishes, when inserting coins once more, above-mentioned work process circulates.Automatically control the display power supply occasion for not needing, available general switch is as the display power supply switch or directly insert the complete machine power-supply system.

Beaer of the present utility model adopts following three kinds of structures according to the metering of difference in functionality power such as boxing, grip, arm strength.

Embodiment 1, is applicable to the beaer of Boxing apparatus.

Fig. 3 is this beaer structure chart.

Fig. 4 is the A-A view of Fig. 3 view.

This beaer (this claims the boxing seat) is formed by hitting power face (1), cushioned material layer (2), feeler lever (3), spring (4) and base (5), one end of feeler lever (3) contacts with the base (5) of beaer, the hole (7) that the other end passes support (6) be installed on support (6) on pick off in flexible component (8) contact.The power face of hitting can be made by whole rubber, and padded coaming can adopt the Sponge of foam and so on, and spring (4) is positioned at and hits between power face (1) and the base (5), makes when hitting power person and hitting power, and a good sensation is arranged.When the boxing masterpiece is used to hit power face (1), move after making stress surface, with it the feeler lever of Lian Jieing also with after move, flexible component (8) on the compressing pick off, elastic component (8) distortion is positioned at the also distortion thereupon of resistance strain gage (ML) on the elastic component (8), resistance changes, make the foil gauge bridge circuit produce voltage signal, be sent to digital display circuit, on display, show the power value of launching an attack.
