Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Fig. 2 is embodiment of the present invention electrical block diagram.
Number in the figure title: 1 platform; 2 support arms; 3 hydraulic cylinders; 4 guide rails; 5,6 pedals; 7,8 limited blocks; 9,10 resistive films; 11,12 moving contacts.
Embodiment
The embodiment of the present invention is just like Fig. 1, shown in 2, this human body accelerates or the ability comparison means of having an effect is provided with a platform 1, the front end of platform is articulated with the upper end of the support arm 2 being fixed on ground, be connected with at the flexible telescoping mechanism of vertical direction between the rear end of platform and ground, the present embodiment stretching structure comprises hydraulic cylinder 3, can also be leading screw jack-up formula or folding-jib during enforcement, those skilled in the art should know how to arrange telescoping mechanism, can stretch at vertical direction to make the rear end of platform, such technology not only belongs to prior art, and belong to the technology that those of ordinary skill just knows.
Platform is provided with two extend to rear guide rail 4 from platform front, the present embodiment guide rail is unsettled polished rod, it can also be the track be laid on guide rail during enforcement, also can be the grooved rail of recessed platform, guide rail is provided with one in front and one in back two pieces of pedals 5, 6, platform is equipped with limited block 7 in the front end of two pieces of pedals, 8, two pedal bottoms are equipped with the resistive film 9 consistent with guide rail direction, 10, the front end (or rear end) of two resistive films to be all connected with same guide rail conducting by the wire of flexing, the present embodiment is that resistive film rear end is connected with guide rail, the wire of flexing can stretch bending, be beneficial to pedal slide and do not affect electrical property, during enforcement, wire can adopt with guide rail and be fixedly connected with or be slidably connected, also directly can be connected by wire.
The front end (or rear end) of two resistive films to be all connected with same guide rail conducting by the wire of flexing, the words, also can be written as: the front end of two resistive films or rear end to be all connected with same guide rail conducting by the wire of flexing, mean: the front end of two resistive films to be all connected with same guide rail conducting by the wire of flexing, or: the rear end of two resistive films to be all connected with same guide rail conducting by the wire of flexing.
Below two pedals, corresponding two resistive films are respectively equipped with the moving contact 11,12 contacted with resistive film be fixed on platform, and form two slide potentiometers R1, R2, slide potentiometer is also called slide rheostat, is also called potentiometer.
During the limited block snap of the front end of two pieces of pedals and respective front end, two moving contacts respectively with the rear end in contact of two resistive films; Direct supply is connected with the first branch road and the second branch road, by direction of current, the moving contact of slide potentiometer R1 connects and composes the first branch road by first node and resistance R3 current limliting, the moving contact of slide potentiometer R2 connects and composes the second branch road by Section Point and resistance R4 current limliting, current sensing means is connected with between first node and Section Point, the present embodiment adopts galvanometer, and galvanometer is the current sensing means measuring Weak current, belongs to conventional electricity instrument.Resistance R3 is identical with resistance R4 resistance.
In other words: R1 and R3 connects, R2 and R4 connects, these two series circuit parallel connections, and and current sensing means formation Wheatstone bridge.
Before the present invention uses, two pedals align with the limited block of its front portion respectively, now two moving contact electromotive forces are identical, galvanometer two ends electromotive force is identical, pointer is motionless between two parties, during use, two people stand on pedal respectively, the start of a race of simultaneously having an effect, and under off acting force promotes, pedal moves along guide rail, resistive film is in company with mobile, two moving contact place electromotive forces change, if electric potential difference is no longer 0, then and galvanometer pointer root deflection, can judge that the acceleration capacity of which people is strong from swaying direction, gap size can be judged from amplitude of fluctuation; First to which direction put from pointer, can judge that whose off reaction is fast, thus reaction velocity ability is passed judgment on.
So the technique effect that the present invention can arrive also comprises: off reaction speed can be detected.Because sportsman reacts duration difference, after hearing off order, the off moment is different, and electric potential difference is non-vanishing, and current sensing means just can show.Those skilled in the art can judge the priority of off action according to galvanometric pointer.
Further, two resistive film resistances are identical, like this can the size of simple comparing motion person's acceleration.Resistance described here, refers to the maximum value of resistive film.We know, the resistance of slide rheostat (being also potentiometer) can change, but slide rheostat has a maximum value, and this maximum value is generally referred to by those skilled in the art as resistance.Such as: buying a resistance is the potentiometer of 1k, it means that purchase maximum value is the potentiometer of 1k.
Further, two resistive film length are identical.When maximum value is identical, resistive film length also identical time, resistance length unanimously just can allow resistance value (resistance value is here effective resistance) identical.
Further, the weightening finish block for increasing pedal quality is also provided with.Athletic body weight may not be identical, in order to compare acceleration, can also arrange the weightening finish block for increasing pedal quality.Those skilled in the art should know Newton second law, for the ease of comparing the different athletic acceleration of body weight, weightening finish block for increasing pedal quality can be set, such as: be set to: pedal quality equals sportsman's quality, or, be set to: pedal quality equals the half of sportsman's quality.How installing fast gaining is routine techniques means.
If do not increase weight block, the size applying strength can be compared from galvanometer.
And the present invention can regulate the gradient of pedal by rear hydraulic cylinder, regulate the resistance of off pedal, and then the stroke under the effect of adjustment pedalling force.
During the invention process, can arrange spring pedal being pushed to its anterior limited block between pedal and platform, pedal can be made like this to have suitable resistance, avoid the too smooth stroke that causes of polished rod excessive, the little slip of reacting force is too fast cannot be off; Can be connected by axle sleeve or linear bearing between pedal with guide rail; Can arrange the start of a race on two pedals and scrunch block, off stable avoiding is skidded; In figure, the limited block of two pedal front portions doublely can do buffer table, flat with pedal one, prolongation that can be suitable as required during design.
The present invention can compare with regard to length, size of having an effect, acceleration magnitude between reaction time of start the people of two acceptance tests.
Be only present pre-ferred embodiments in sum, all equivalence modifications of doing according to the application and prior art are added and are all considered as the technology of the present invention category.
