Embodiment
As shown in Figure 1, be the structural representation of first embodiment of the invention, the flap simulating device of present embodiment comprise hit the son 1, be used to bounce liquid crystal display equipment screen; Elastic force unit 2 and hits son and 1 links to each other, is used for after producing elastic deformation, provides energy for hitting sub 1 bump.
The flap simulating device of present embodiment at work, elastic force unit 2 is produced elastic force behind the force-extension, have elastic potential energy, hits son 1 owing to link to each other with elastic force unit 2, so also has potential energy.Abrupt release elastic force unit 2, elastic potential energy are converted into the kinetic energy that hits son 1, produce momentum in sub 1 short time thereby make to hit, and can clash into liquid crystal display equipment screen.The kinetic energy that elastic force unit 2 can repeat to provide same is to hitting son 1, and the size of its kinetic energy can be controlled by the elasticity coefficient and the deformation size of regulating elastic force unit 2 according to the actual conditions needs.
Present embodiment combines anthropomorphic dummy's hand-power amount and bounces LCD with hitting son 1 by elastic force unit 2, by regulating the different dynamics of bouncing and the processes of related coefficient simulation of elastic force unit 2, realizes mechanization, the standardization of the process of bouncing.
As shown in Figure 2, be the structural representation of second embodiment of the invention, the flap simulating device of present embodiment comprises and hits son 1, elastic force unit 2, slideway 3, stressed support 4.Hit son 1 and be used to bounce liquid crystal display equipment screen; Elastic force unit 2 with hit son and 1 link to each other, be used for after producing elastic deformation, provide energy for hitting sub 1 bump; Particularly, hit son 1 and link to each other with elastic force unit 2 by stressed support 4, and hit sub 1 and be placed in the slideway 3, elastic force unit 2 is fixed on the slideway 3.
Particularly, hitting son 1 shape size, material and quality can be according to treating that the simulated conditions difference adjusts.Elastic force unit 2 also can adopt various material, selects spring in the present embodiment for use.It is discoid to hit being shaped as of son 1, and diameter is 8cm, and weight is 0.3kg, and material is an acryl resin.Hit sub 1 top and be provided with a stressed support 4, the stressed support 4 of present embodiment adopts connecting link, and stressed support 4 links to each other with the upper end of elastic force unit 2.Slideway 3 is a tubular, opens several trough on the barrel of slideway 3, places elastic force unit 2 in the groove.The lower end of elastic force unit 2 is fixed on the groove of barrel.The size and the size of groove on the barrel are set, spring can be stretched arbitrarily therein.
The described flap simulating device of present embodiment in the course of the work, on to draw stressed support 4 be connecting link, because of stressed support 4 links to each other with the upper end of elastic force unit 2, and the lower end of elastic force unit 2 is fixed on the groove of barrel of slideway 3, so being spring, elastic force unit 2 is stretched, the back that stretches produces elastic force, and elastic force unit 2 has elastic potential energy, thereby makes and hit son 1 and have potential energy.The stressed support 4 of abrupt release hits son 1 potential energy and is converted into kinetic energy, after hitting son 1 and obtaining kinetic energy, bounces liquid crystal display equipment screen, and spring shrinks after bouncing, and drives to hit son 1 and return, and finishes the process of once bouncing.In the practical operation, can be provided with stretching strength, tensile elongation, spring elasticity coefficient, hit sub-weight, hit son 1 after once bouncing LCD screen thereby make, kinetic energy moment diminishes, and vibrates near equilibrium state, and contact screen for the second time not.In the present embodiment, being provided with and hitting son 1 is 1/3 of spring length with the distance of screen under equilibrium state, hits son 1 after once bouncing screen thereby make, and can not bounce screen for the second time, with the harmful effects such as reappearance that prevent that secondary impact from bringing.The kinetic energy that elastic force unit 2 can repeat to provide same is to hitting son 1, and its kinetic energy can according to circumstances need to control by the elasticity coefficient and the deformation size of regulating elastic force unit 2.
The slideway 3 of present embodiment by tubular is set can limit and hit son 1 direction of motion, make hit son 1 in the range of control of slideway 3 promptly the barrel along slideway 3 move up and down, to prevent the randomness of its bump.
As shown in Figure 3, be the structural representation of third embodiment of the invention, the flap simulating device of present embodiment comprises and hits son 1, elastic force unit 2, slideway 3, stressed support 4.Hit son 1 and be used to bounce liquid crystal display equipment screen; Elastic force unit 2 with hit son and 1 link to each other, be used for after producing elastic deformation, provide energy for hitting sub 1 bump; Particularly, hit son 1 and link to each other with elastic force unit 2 by stressed support 4, and hit sub 1 and be placed in the slideway 3, elastic force unit 2 is fixed on the slideway 3.
In the present embodiment, that hits son 1 is shaped as discoidly, and diameter is 8cm, and weight is 0.3kg, and material is an acryl resin.Different with a last embodiment is, the stressed support 4 that is arranged at slideway 3 inside is that connecting link links to each other with an end of elastic force unit 2, and elastic force unit 2 is a rubber band, and elastic force unit 2 is that the other end of rubber band is fixed in the groove of slideway 3 barrels.During work, on draw stressed support 4, produce elastic force thereby rubber band is stretched, have elastic potential energy, drive and hit son 1 and produce potential energy, the stressed support 4 of abrupt release, potential energy moment of hitting son 1 is converted into kinetic energy, obtains to clash into LCD screen behind the kinetic energy.When equilibrium state, the distance of hitting son 1 and screen is 1/4 of slideway 3 width.After hitting son 1 bump screen, kinetic energy moment diminishes, near equilibrium state, vibrate, and contact screen for the second time not.
As shown in Figure 4, be the structural representation of fourth embodiment of the invention, the flap simulating device of present embodiment comprises and hits son 1, elastic force unit 2, slideway 3, stressed support 4.Hit son 1 and be used to bounce liquid crystal display equipment screen; Elastic force unit 2 with hit son and 1 link to each other, be used for after producing elastic deformation, provide energy for hitting sub 1 bump; Particularly, hit son 1 and link to each other with elastic force unit 2 by stressed support 4, hit son 1 and be placed in the slideway 3, stressed support 4 passes slideway 3 and hits sub 1 and be connected with elastic force unit 2 for propping up to name a person for a particular job with slideway 3.
In the present embodiment, hit son 1 for discoid, diameter is 8cm, weight is 0.3kg, material is an acryl resin, hit sub 1 top and be provided with a stressed support 4, this stressed support 4 is identical with the principle of work of lever, and stressed support 4 passes slideway 3 and hits son 1 for naming a person for a particular job with slideway 3 and be connected with elastic force unit 2.In the stressed support 4 with hit son 1 part that links to each other and be positioned at slideway 3 inside, can be up and down and stretch out slideway 3 parts outward, and link to each other with an end of elastic force unit 2.Elastic force unit 2 is a spring, is arranged at the outside of slideway 3, and its other end can be fixed on the barrel of slideway 3.During work, because the upper end of spring is fixed, as shown in Figure 4, to the part outside the slideway 3 of stretching out that presses down stressed support 4, produce elastic force thereby spring is stretched, drive and hit generation potential energy in sub 1 short time, moment is removed power from lever, hitting son 1 potential energy moment is converted to kinetic energy, obtains to clash into LCD screen behind the kinetic energy.Elasticity coefficient and the big or small adjustment that realizes the kinetic energy of head-on collision 1 of deformation by adjusting the elastic force unit can also utilize lever adjusting momentum simultaneously.
