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, since the first and second rocking frames 30,50 are similar in structure and operate similarly in the aforementioned embodiment of the present invention, the operation of the second rocking frame is taken as an example, as shown in fig. 4 and 5, since the distance between the two left cantilevers 52 is narrow at the top and wide at the bottom, and the distance between the two right cantilevers 54 is narrow at the top and wide at the bottom, when the second rocking frame 50 swings back and forth, the second rocking frame will slightly tilt or change its angle, so that people can feel comfortable and relaxed.
The operation features of the base of the present invention can be compared with two comparative examples, and the first comparative example is shown in fig. 6, if the two left cantilevers 52a are changed into a structure with a wide top and a narrow bottom, the actions thereof are completely different, as shown in fig. 7, the second cradle 50a tilts forward when swinging forward, and as shown in fig. 8, the second cradle 50a tilts backward when swinging backward, so that the user has a feeling of being swung out, which is not stable. In contrast to the base 10 of the present invention, as shown in fig. 4, the second cradle 50 tilts itself backward when it swings forward, and as shown in fig. 5, the second cradle 50 tilts itself forward when it swings backward, giving the user a feeling of being covered and being stable when it is used. 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 by many experimental tests, which can allow the user to relax fully, and even solve part of the insomnia problem, and through practical tests, when the first cradle 30 and the second cradle 50 are located at the center point of the swing stroke, the included angle between each cantilever 36,37,52,54 and the vertical line is preferably 4-12 °, less preferably 5-10 °, and most preferably 6-8 °, and the included angle is about 7 ° in the previous embodiment. Based on the design spirit of the present invention, the structure 10 of the base can be designed in other variations, for example, the first and second driving devices can be other mechanisms with reciprocating driving function, and all such variations that are easy to be considered are all covered by the scope of the present invention.
