Abstract
The invention relates to an impact force electrical signal conversion device, which comprises a force acceptor 1 consisting of polyurethane material and a metal base, an ejector rod 4 and an adjusting bolt 5 connected with the force acceptor, a moving guide rail 2, a rest spring 3, a piezoelectric film sensor 6 and a protection steel sheet 7 outside the piezoelectric film sensor 6. The guide rail is connected with a frame. When the force acceptor is impacted, the ejector rod 4 axially moves in the moving guide rail 2, the bolt 5 screwed on a fixed rod impacts the piezoelectric film sensor 6 protected by the steel sheet, and the sensor generates a voltage signal in directly proportional to the impact force, and the signal is output through a sensor lead-out line 10. The device has the advantages of simple structure, accurate force measurement and good impact force sensing, which can be applied to the physical training for boxing, free combat, kickboxing, martial art and other kinds of combats.
Description
Technical field
The invention belongs to the dynamometry parts of the physical culture device of training tae kwon do, boxing and wushu.
Background technology
The used sensor of boxing training device that uses mainly contains resistance strain gage, grating displacement sensor and electromagnetic sensor at present, but these sensors exist poor linearity, poor stability, life-span is short, and critical defect such as cost height, to such an extent as to these training aids can not drop into normal use.The present invention has adopted up-to-date sensor technology, has realized that dynamometry is accurate, good stability, and the life-span is long, and price is low, and it is simple in structure to add the present invention, can reduce the machine cost of tae kwon do and shadowbox machine, thereby the present invention has great practical value.
Summary of the invention
The object of the present invention is to provide a kind of impulsive force that piezoelectric film sensor can be subjected to convert the device of the signal of telecommunication to, for the detailed achievement data of the ability that impacts that utilizes accurate demonstration of single chip circuit system and count off trainer provides reliable assurance.
Operation principle of the present invention is: after beaer is impacted, beaer drives push rod bump piezoelectric film sensor, piezoelectricity biography film sensor produces the corresponding linear output voltage signal according to the size of distortion, and this signal converts data signal to by display demonstration and the count off of driving sound circuit through single chip computer measurement system.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present invention is described in further detail.
In structure shown in Figure 1; hit the beaer 1 that force electrical signal conversion device is made up of polyurethane material and metal base, with the push rod 4 that beaer connects together, motion guide rail 2; back-moving spring 3, the protection steel disc 7 of adjustment screw 5 and piezoelectric film sensor 6 and its outside is formed.After beaer is impacted; push rod is axially-movable in motion guide rail; be screwed in the screw of deciding on the bar 5 and can clash into the piezoelectric film sensor of being protected by steel disc 6, sensor can produce a voltage signal that is directly proportional with impulsive force, and this signal is through 10 outputs of sensor lead-out wire.
The available synthetic leather of the face that impacts of the beaer of this device is wrapped, to prolong the life-span of beaer.The synthetic leather protective sleeve can be used as consumable accessory and changes.This device can be used as digital the demonstration or the digital sports equipment dynamometry parts that add the voice count off that show, for example impact force electrical signal conversion device of boxing or tae kwon do training airplane.
The polyurethane beaer of this device must be used Mold Making, and the beaer metal base should be made of one with the polyurethane beaer, and the push rod of impact microphone also should fuse with the beaer pedestal.Piezoelectric film sensor wraps with adhesive tape with individual layer or the protection of double-deck steel disc, and the length of steel disc is greater than the length of piezoelectric film sensor, and holes at the tail end of steel disc, is fixed on the frame 9 with bolt 8.Push rod need go out big footpath and path with the lathe car, and big footpath size equals the internal diameter of guide rail 2, and path equals the internal diameter of spring 3.Guide rail and frame will fuse.
Claims (4)
1. one kind comprises the beaer of being made by metal base and polyurethane material, the impact force electrical signal conversion device that piezoelectric film sensor is formed.The pedestal of beaer 1 links to each other with push rod 4, it is characterized in that beaer is subjected to impacting the back and drives push rod bump piezoelectric film sensor.
2. electrical signal conversion device according to claim 1 is characterized in that piezoelectric film sensor protected by the single or double steel disc.
3. electrical signal conversion device according to claim 1 is characterized in that the push rod that links to each other with pedestal resets by spring 3.
4. electrical signal conversion device according to claim 1 is characterized in that being screwed with adjustment screw 5 on the push rod 4, is used to regulate the distance with sensor.
