Abstract
The invention discloses a vibration damping device for step climbing and relates to a mechanical device. The vibration damping device for the step climbing is characterized by consisting of a bracket (1) and two flexible wheels (2), wherein each flexible wheel (2) consists of pulleys (3), telescopic legs (4), tension and compression springs (5), swing legs (6), torsion springs (7) and a wheel disc (8); the two flexible wheels are contacted with a step surface through flexible legs; the wheel disc is connected with three flexible legs through hinges; each flexible leg is formed by connecting one of the swing legs and the corresponding telescopic leg, and the flexible legs form a sliding pair; the tension and compression springs are respectively arranged at joints of the swing legs and the telescopic legs; while the flexible legs are connected with the wheel disc through the hinges, the three torsion springs are respectively connected with the three swing legs; the tail end of each telescopic leg is provided with the corresponding pulley. According to the vibration damping device disclosed by the invention, the flexible wheels are contacted with the step surface through the flexible legs, so that running is more stable, and vibration generated during a motion process is obviously damped, and therefore, the effects that vibration is steadily damped and the noise is small are achieved during a step climbing process.
Description
Technical field
The present invention relates to a kind of mechanical device, particularly relate to one and climb ladder shock attenuation unit.
Background technology
Transmit article by step at present or the disabled's stair activity is all a difficult problem, if this device is added on freight trolley or wheelchair, can drive go-cart or wheelchair to creep on step, and can make vibration reduce, ensure people and goods steadily.
Summary of the invention
The object of the present invention is to provide one to climb ladder shock attenuation unit, this device compliant wheel contacts with step surface by flexible leg, moves more steadily, has significantly reduced the vibration producing in motion process, thereby in the process of climbing ladder, reach steady vibration damping, the effect that noise is little.
The object of the invention is to be achieved through the following technical solutions:
One is climbed ladder shock attenuation unit, and described device is made up of bracket and two compliant wheel, wherein compliant wheel by pulley, Retractive leg, drawing-pressing spring, lead leg, torsion spring and wheel disc form; Compliant wheel contacts with step surface by flexible leg, wheel disc three flexible legs that are connected through the hinge, each flexible leg is formed by connecting with Retractive leg by leading leg, and form moving sets, drawing-pressing spring is all housed in junction, when flexible leg is connected through the hinge wheel disc, uses three torsion springs to connect respectively three and lead leg, Retractive leg end is equipped with pulley.
Advantage of the present invention and effect are:
1. wheel disc of the present invention three flexible legs that are connected through the hinge, each flexible leg is formed by connecting with Retractive leg by leading leg, form moving sets, and drawing-pressing spring is all housed in junction, Retractive leg can be stretched, play buffering absorbing effect, reduce vibration, impact when buffering leg falls contact step surface.Reach and the object of ledge surface flexible contact, reduce vibration.
2. when flexible leg of the present invention is connected through the hinge wheel disc, using three torsion springs to connect leads leg and wheel disc, each the leading leg of wheeling disk structure restriction can swing within the scope of 30 ~ 120 degree, ensure the hands-off while each other, can ensure that previous flexible leg not yet exits and the contacting of step, next flexible leg has entered contact, has certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, transmission is more steady.Two kinds of elastic element double damping designs can reduce user's uncomfortable impression because jolting and producing in upper process downstairs as far as possible.
Brief description of the drawings
Fig. 1 is integral structure schematic diagram of the present invention;
Fig. 2 is compliant wheel structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
This device is made up of bracket 1 and two compliant wheel 2, wherein compliant wheel 2 by pulley 3, Retractive leg 4, drawing-pressing spring 5, lead leg 6, torsion spring 7 and wheel disc 8 form.When work, compliant wheel contacts with step surface by flexible leg, and the operation of this device is more steady, has significantly reduced the vibration that produces in motion process, thereby in the process of climbing ladder, has reached steady vibration damping, the effect that noise is little.
Wheel disc three flexible legs that are connected through the hinge, each flexible leg, by leading leg and Retractive leg is formed by connecting, forms moving sets, and drawing-pressing spring is all housed in junction, Retractive leg can be stretched, play buffering absorbing effect, reduce vibration, impact when buffering flexible leg falls.Reach and the object of ledge surface flexible contact, reduce vibration.When flexible leg is connected through the hinge wheel disc, using three torsion springs to connect respectively three leads leg, each the leading leg of wheeling disk structure restriction can swing within the scope of 30 ~ 120 degree, ensure the hands-off while each other, can ensure that previous flexible leg not yet exits and the contacting of step, next flexible leg has entered contact, has certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, make transmission more steady.Retractive leg end is equipped with pulley, and cliding friction is transformed into friction of rolling, reduces resistance, moves brisk.
Firmly pull bracket 1, the wheel disc of compliant wheel 2 rotates, when described flexible leg is connected through the hinge wheel disc, uses three torsion springs to connect and lead leg, each the leading leg of wheeling disk structure restriction can swing within the scope of 30 ~ 120 degree, ensure the hands-off while each other, can ensure that previous flexible leg not yet exits and the contacting of step, next flexible leg has entered contact, has certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, transmission is more steady.Wheel disc is rotated further, and device travels forward by pulley, and in the time that pulley runs into step, wheel disc is rotated further next flexible leg and contacts with subsequent another step, and real-time ensuring has two legs in contact, does not impact and collision.Climb successively like this, play buffer action, more steady while making device Pa building.
