Detailed description of the invention
Embodiment: as Figure 1-4, a kind of table tennis companion trainer, comprises body 1, lifting platform 3, bulb separation mechanism and kicking machine; Lifting platform 3 is connected with fixed block 6, fixed block 6 has ball groove 7, has a guide groove 9 in ball groove 7, and guide block 16 is arranged in guide groove 9; Described bulb separation mechanism comprises E shape mechanism, motor, the cam 10 be connected with motor and the guide rod 11 hinged with cam 10, guide rod 11 is hinged with guide block 16, the vertical pole 15 that described E shape mechanism comprises the first cross bar 12, second cross bar 13, the 3rd cross bar 14 and is connected with each cross bar respectively, 3rd cross bar 14 is hinged with guide rod 11, E shape branch construction is in the both sides of ball groove 7 notch and be hinged on fixed block 6 by vertical pole 15, and the first cross bar 12 compared with the second cross bar 13 closer to the pin joint of vertical pole 15 with fixed block 6.Concrete, driven by motor cam 10 rotates, the motion of guide rod 11 in the vertical direction is driven when cam 10 rotates, guide rod 11 drives the 3rd cross bar 14 of E shape mechanism to move, the direction of motion of guide block 16 in guide groove 9 to the 3rd cross bar 14 limits, the 3rd cross bar 14 one end in the vertical direction hinged with guide rod 11 is moved, thus move in the horizontal direction in the 3rd cross bar 14 one end hinged with vertical pole 11, again because vertical pole 15 and fixed block 6 are hinged, the lengthwise movement of the 3rd cross bar 14 is made to be transformed into vertical pole 15 with the straight line of the tie point place longitudinal direction of itself and fixed block 6 for axis swings, due to the first cross bar 12 compared with the second cross bar 13 closer to vertical pole 15 pin joint with fixed block 6, thus the distance between the first cross bar 12 achieving two relative E shape mechanisms is maximum when the 3rd cross bar 14 vertical motion peaks, it is minimum when the 3rd cross bar 14 vertical motion touches the bottom, and the second cross bar 13 is contrary with the first horizontal 12 bars, distance between second cross bar 13 of two E shape mechanisms is minimum when the 3rd cross bar 14 vertical motion peaks, it is maximum when the 3rd cross bar 14 vertical motion touches the bottom.
When the 3rd cross bar 14 vertical motion peaks, distance between first cross bar 12 of two relative E shape mechanisms is maximum, table tennis falls between the first cross bar 12 and the second cross bar 13 by the opening between two the first cross bars 12, because the distance between two the second cross bars 13 is minimum, now table tennis is tackled by the second cross bar 13; When the 3rd cross bar 14 vertical motion touches the bottom, distance between first cross bar 12 of two relative E shape mechanisms is minimum, new table tennis cannot be dropped into by the opening between two the first cross bars 12 between first cross bar 12 and the second cross bar 13, because the distance now between two the second cross bars 13 is maximum, table tennis is fallen by from the opening between two the second cross bars 13, fall into lifting platform from ball groove 7, limit its position by catch 4.
One end and the body 1 of described lifting platform 3 are hinged, and the other end of lifting platform 3 is connected with body 1 by elevating mechanism 2, and elevating mechanism 2 is pinion and rack, for adjusting the injection angle of table tennis; Kicking machine comprises the catch 4 be arranged on lifting platform, block 8 and elasticity driving lever 5, described elasticity driving lever 5 to be connected with motor and can at the lifting platform 3 surface driving lever that rotate, block 8 to be placed between elasticity driving lever 5 and catch 4 and block 8 and catch 4 be arranged on the position of lifting platform 3 and elasticity driving lever 5 lifting platform 3 is surperficial rotate time inswept lifting platform 3 area there is intersection.Elasticity driving lever 5 rotates the position to block 8, by the drag effect of catch 4, there is deformation in elasticity driving lever 5, deformation produces elastic force, until there is the position that deformation is enough to spend block 8 in elasticity driving lever 5, resilient force is on catch 4, and elastic force is passed to the table tennis falling into lifting platform 3 by catch 4, and table tennis is penetrated.
In the present embodiment, the batting end of elasticity driving lever 5 is concordant with 1/5-1/3 place more than block 8 bottom surface, the batting end of elasticity driving lever 5 is concordant with 2/3-4/5 place more than catch 4 bottom surface, can according to concordant height, change the deformation degree of elasticity driving lever 5, and then change the elastic force of table tennis acquisition, thus make the injection dynamics of table tennis adjustable.
