[0043] The second driving device 60 includes a second power source 61, a second crank 66 and a second link 68, the second power source 61 is provided at the chassis 34 of the first pan 30 and includes a second The motor 62, a second reduction mechanism 63, and a second output shaft 64 extending in the left-right direction, the second speed reduction mechanism 63 transmits the power of the second motor 62 to the second output shaft 64, the second crank One end is connected to the second output shaft 64, which is respectively pivoted to the second crank 66 and the second shaker 50, respectively, and the second drive device 60 can drive the second. The shaker 50 is swung before and after the first rack 30, such as Figure 4 , Figure 5 Indicated.
[0044]Through the above configuration, the base 10 of the present invention can make a bed, a chair or a sofa, or the left and right swings thereon, and the trajectory of the swing is substantially a circular arc shape facing up, especially when the first drive 40 When the second drive device 60 is simultaneously acting, if the first output shaft 44 is different from the second output shaft 64, the function of the universal swing can be created, and more variable use experience can be provided. The user feels monotonous and is easy to tired, in addition, if Figure 3 to 5 As shown, it is designed by the narrow width of each cantilever 36, 37, 52, 54, so that the first rocker 30 is moderately inclined in the angle, neither tilt. People feel unstoppable, and will not be too gentle to feel mechanical monotonous, in line with ergonomics, so that users feel comfortable and comfortable and can fully relax, thus achieving the purpose of the invention.
[0045] Further, since the first power source 41 and the second power source 61 are provided in the chassis 34 of the first rocker 30, the overall center of gravity is lowered, and the base 10 can be reduced, effectively improve the smooth operation. degree.
[0046] The operation characteristics of the present invention will be described in detail below. Since the structure of the present invention, the structure of the first and second shafts 30, 50 is similar, the action is also similar, so the operation of the second thread is described as an example, such as Figure 4 , Figure 5 As shown, since the pitch of the two left hanging arm 52 is narrow, the pitch of the two-or-right cantilever 54 is narrow, so that the second shaker 50 is swayed before and after, it will be slightly tilted or changed from the angle. People feel comfortable, relaxing, compared to the swinging of a single hanging point, the angle of itself is much larger, making people feel stimulating.
[0047] The action characteristics of the base of the present invention can be further lifted to the secondary example, and the first comparison is, for example, Figure 6 As shown, if the two left cantilear 52a is changed to a narrow structure, the action will be completely different, such as Figure 7 As shown, it is inclined forward when the second shaker 50a is swing forward. Figure 8 As shown, it is tilted backward when the second shaker 50a is swing, so that the user has the feeling of being swayed, and it is more uncomfortable. Also discover the base 10 of the present invention, such as Figure 4 As shown, it is inclined backward when the second shaker 50 is swing forward. Figure 5 As shown, it is inclined forward when the second shaker 50 is swinging, so that the user has the feeling of being covered, and it is more secure. The second comparative example is like Figure 9 As shown, if the two left hanging arm 52b is changed to each other, the action will be different, such as Figure 10 As shown, the angle of itself is unchanged when the second shaker 50b is swung (ie, it will not be tilted), such as Figure 11 As shown, the angle itself does not change when the second shaker 50b is swing (ie, it will not be tilted), and the user's feeling is compared to mechanical monotors, which is easier to fatigue or boring.
[0048] In other words, the design of the present invention has passed through many experimental tests, which allows the user to fully relax, and even solve some of the problems of some insomnia, after the actual test, when the first rack 30 and the second When the shaker 50 is located in the center point of the swing stroke, the angle between the cantilever 36, 37, 52, 54 and the lead line is preferably 4-12 °, and the secondary is 5-10 °, and the optimum is 6-8. °, which is about 7 ° in the foregoing embodiment. Based on the design spirit of the present invention, the structural 10 of the base can have other variations. If the first, the second drive can employ other mechanisms with reciprocating drive function, and the ease of thinking, the like, and should be the present invention. The application is covered by the patent.
