Abstract

A driving device for a shaking table or a shaking chair comprises a table body or a chair body, a swing lever and a motor, wherein the table body or the chair body is hung on the swing lever; a thumbwheel is arranged on the rotating shaft of the motor; a plurality of picks are arranged on the thumb wheel; a horizontal guide rod is fixed under the table body or the chair body; a swing body slidingblock is sleeved on the horizontal guide rod; collision vertical planes are arranged on the swing body sliding block in the swinging direction and in the reversed swinging direction, repetitively; two collision vertical planes are parallel to each other and form a deflection angle with the horizontal guide rod; the thumb wheel is positioned under the swing body sliding block; and the length of the picks is greater than the closest distance from the profile of the thumb wheel to the bottom surface of the swing body sliding block. The utility model has the advantages of simple structure, low failure rate, great swinging amplitude, long service life and the like, and overcomes the defects of higher noise and greater vibration of the traditional shaking table or shaking chair. Meanwhile, theswing body can naturally swing, so that the swinging motion thereof is similar to the manual pushing motion and soft, and people can not only have a good rest insensibly but also recapture the feelingof childhood.

Description

The drive unit of shaking table or rocking chair

Technical field

The utility model relates to a kind of electric swinging device, especially relates to the drive unit of a kind of shaking table or rocking chair.

Background technology

Present common shaking table (comprising Children and adult's shaking table) or rocking chair etc. wave furniture needs people to promote just can wave, and all is to choose to push away as power to make its swing.A lot of inconvenience is arranged in the use.And need be continuously applied external force, swing just can be kept down.For this reason, people have designed electric cradle and rocking chair substitutes manually, these electric cradles and rocking chair mostly with motor as power, drive a body or the chair body shakes by certain transmission mechanism and oscillating control mechanism.Yet the design of the drive unit of existing electric cradle and rocking chair is reasonable inadequately, exists transmission mechanism and oscillating control mechanism complexity, is out of order easily; The long-time running motor easily generates heat, and service life is short, even causes motor to burn out; The production cost height makes product be difficult to problems such as most of people accepts because of price is too high.

Summary of the invention

The utility model purpose provides the drive unit of a kind of shaking table or rocking chair.With the existing complex structure of rocking equipment that solves, easy break-down, noise is big, price high-technology problem.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: it comprises a body or chair body, fork, motor, described bed body or chair body overhang are on fork, described shaft of motor is provided with thumb wheel, thumb wheel is provided with some plectrums, be fixed with horizontal guide under bed body or the chair body, be arranged with the pendulum mass slide block on the horizontal guide, on the positive and negative swaying direction of pendulum mass slide block, respectively be provided with a collision vertical plane, two collision vertical planes are parallel to each other and constitute a drift angle with horizontal guide, described thumb wheel is under the pendulum mass slide block, and the length of its plectrum is greater than the minimum distance of thumb wheel profile to the bottom surface of pendulum mass slide block.

As preferably, described horizontal guide is provided with dive key.

As preferably, described thumb wheel is provided with 2-4 plectrum.

As preferably, the striking face of the both sides of described pendulum mass slide block is provided with pulley.

The utlity model has simple in structure, fault rate is low, amplitude of fluctuation is big, advantages such as long service life have overcome traditional shaking table or rocking chair noise and vibration defective such as bigger.Simultaneously, be swing naturally of waving body owing to wave, so it wave with manually promotion is similar, very soft, can allow people well had a rest, and experience the sensation in childhood.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

Fig. 1 is the front view of a kind of preferred implementation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Working state schematic representation when Fig. 3 is preferred implementation forward shown in Figure 1 swing;

Working state schematic representation when Fig. 4 is preferred implementation backswing shown in Figure 1.

The specific embodiment

Fig. 1 is the front view of a kind of preferred implementation of the present utility model, and Fig. 2 is its A-A cutaway view; By Fig. 1 and in conjunction with Fig. 2 as can be known, the drive unit of this shaking table or rocking chair is by support 1, motor 5, formations such as bed body or chair body 3.Described bed body or chair body 3 are suspended on the fork 2, and fork 2 serves as the swing fulcrum with balance staff 10 then.

Be fixed with the horizontal guide 9 parallel on the suspension rod 4 under bed body or the chair body with balance staff 10, on horizontal guide 9, be axially arranged with at least one dive key 91, be arranged with pendulum mass slide block 7 on the horizontal guide 9, accordingly, in the slideway of pendulum mass slide block 7, be provided with keyway, pendulum mass slide block 7 can move axially on horizontal guide 9, and the striking face in the both sides of pendulum mass slide block 7 is provided with pulley 71.

At two vertical sides of pendulum mass slide block 7, promptly respectively be provided with collision vertical plane 8, two collision vertical planes 8 on the swaying direction of pendulum mass slide block 7 and be parallel to each other and constitute a drift angle α with horizontal guide 9, the optimized angle of this drift angle α is 40-70 °.

The rotating shaft of motor 5 is provided with thumb wheel 6, and 2-4 plectrum 61 arranged on thumb wheel 6.

When chair lift is static, thumb wheel 6 be positioned at pendulum mass slide block 7 under, the length of its plectrum 61 is greater than the minimum distance of thumb wheel 6 profiles to the bottom surface of pendulum mass slide block 7.

Working state schematic representation when Fig. 3 is the swing of this preferred implementation forward.As known in the figure, after motor 5 started, thumb wheel 6 turned clockwise, 61 pairs of pendulum mass slide block 7 works done of plectrum.So pendulum mass slide block 7 drives chair lift and plays pendulum, in the forward swing process, behind the pulley 71 contact normal impact vertical planes 81, be subjected to the inclined-plane power effect of normal impact vertical plane 81, the flat downstream guide rod 9 of pendulum mass slide block 7 moves to the B point.

Working state schematic representation when Fig. 4 is the backswing of this preferred implementation.By Fig. 4 further as can be known, chair lift is positioned at high oppositely backswing of some back, because pendulum mass slide block 7 positions are at the B point, when it passes through plectrum 61, bump less than plectrum 61, therefore smoothly by the anti-collision of thumb wheel 6 back contacts vertical plane 82, be subjected to anti-ramp effect of colliding vertical plane 82, the flat downstream guide rod 9 of pendulum mass slide block 7 moves to the A point.Then, chair lift is positioned at forward backswing immediately behind the high point, and when pendulum mass slide block 7 is rocked to low spot, plectrum 61 is once more to 7 works done of pendulum mass slide block.Like this, the above process of the repetition that goes round and begins again just can realize that shaking table or rocking chair swing continuously.Pendulum mass slide block 7 is under the effect of positive and negative collision

vertical plane

81,82, and it is all the time at A, moves between 2 of the B.The distance that A, B are 2 is substantially equal to collide the width of the projection width+pendulum mass slide block 7 of vertical plane 8 on pendulum mass slide block 7 swaying directions.
