With the above structure, the base 10 of the present invention can make the bed, chair or sofa installed thereon swing back and forth or side to side, and the swing track is roughly in the shape of an arc with an upward opening, especially when the first driving device 40 and the second driving device 60 act simultaneously, if the rotation speeds of the first output shaft 44 and the second output shaft 64 are different, a universal swing function can be created, providing more variable use experience, avoiding the user from feeling monotonous and easily tired, furthermore, as shown in fig. 3 to 5, by the design of narrow upper portion and wide lower portion of the distance between the cantilevers 36,37,52,54, the proper tilt angle of the first cradle 30 and the second cradle 50 when swinging can be neither too tilted to feel unstable, nor too gentle to feel mechanical monotonous, conforming to human engineering, and making the user feel comfortable and fully relaxed, thereby achieving the purpose of the utility model.
Moreover, since the first power source 41 and the second power source 61 are both disposed on the bottom frame 34 of the first rocking base 30, the center of gravity of the whole can be lowered, and the base 10 can be reduced from rocking, thereby effectively improving the smoothness of operation.
The operation features of the present invention will be described in detail below, because the present invention in the above embodiment, the first and second rocking frames 30,50 are similar in structure and the same in operation, so the operation of the second rocking frame is exemplified, as shown in fig. 4 and 5, because the distance between the two left cantilevers 52 is narrow and wide, and the distance between the two right cantilevers 54 is narrow and wide, when the second rocking frame 50 swings back and forth, the second rocking frame itself will incline slightly or change the angle, so that the user can feel comfortable and relaxed.
The action characteristics of the base of the utility model can be compared and explained by two comparative examples again, the first comparison is shown in fig. 6, if two left cantilevers 52a are changed into a structure with wide upper part and narrow lower part of the space, the action can be completely different, as shown in fig. 7, when the second cradle 50a swings forwards, the second cradle 50a inclines forwards, and as shown in fig. 8, when the second cradle 50a swings backwards, the second cradle inclines backwards, so that the user has the feeling of being swung out, and the base is not stable. Inversely, the base 10 of the present invention, as shown in fig. 4, inclines backward when the second cradle 50 swings forward, and inclines forward when the second cradle 50 swings backward as shown in fig. 5, so that the user has a feeling of being covered, and is stable during use. In the second comparative example, as shown in fig. 9, if the two left suspension arms 52b are changed to a structure parallel to each other, the operation is different, and as shown in fig. 10, the angle of the second cradle 50b is not changed (i.e., it does not tilt) when it swings forward, and as shown in fig. 11, the angle of the second cradle 50b is not changed (i.e., it does not tilt) when it swings backward, which gives a user a mechanically monotonous feeling and is easy to get tired or boring.
In other words, the design of the present invention is the best mode obtained after many experimental tests, which can let the user fully relax, even solve the problem of partial insomnia, and through practical tests, when the first cradle 30 and the second cradle 50 are located at the central point of the swing stroke, the included angle between each cantilever 36,37,52,54 and the plumb line is preferably 4-12 °, preferably 5-10 °, more preferably 6-8 °, and the included angle is about 7 ° in the foregoing embodiment. Based on the design spirit of the utility model, the structure 10 of this base can have other change designs, can adopt other mechanisms that have reciprocating drive function like this first, two drive arrangement, holds the change that these easily think about, all should do the utility model discloses the application of patent scope covers.
