藉由上述的結構，本創作之底座10可令設於其上的床、椅或沙發前後或左右搖擺，且搖擺的軌跡大致呈一開口朝上的圓弧形，特別是當該第一驅動裝置40與該第二驅動裝置60同時作用時，若該第一輸出軸44與該第二輸出軸64的轉速不同，則可創造出萬向搖擺的功能，提供更多變的使用體驗，可避免使用者感覺動作單調而容易疲乏，此外，如第3至5圖所示，藉由各懸臂36, 37, 52, 54間距上窄下寬的設計，使得該第一搖架30與該第二搖架50搖擺時適度的傾斜本身角度，既不會太過傾斜讓人感覺不安定，又不會太過平緩讓人覺得機械單調，符合人體工學，讓使用者覺得安穩舒適而能充分放鬆，從而達成本創作的目的。With the above-mentioned structure, the base 10 of the present invention can make the bed, chair or sofa set on it swing back and forth or left and right, and the trajectory of the swing is generally in the shape of an arc with the opening facing upward, especially when the first drive When the device 40 and the second driving device 60 act at the same time, 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 a more varied user experience. To prevent the user from feeling monotonous and easily fatigued, in addition, as shown in Figures 3 to 5, with the narrower and wider widths of the cantilevers 36, 37, 52, and 54, the first cradle 30 and the first The second cradle 50 is tilted at an appropriate angle when swinging. It will not be too tilted to make people feel uneasy, nor too gentle to make the machine monotonous, ergonomic, so that the user feels stable, comfortable and fully Relax to achieve the purpose of cost creation.

再者，由於該第一動力源41與該第二動力源61均設於該第一搖座30之底架34，讓整體的重心得以壓低，且可減少底座10晃動，有效提升運作的順暢度。Furthermore, since both the first power source 41 and the second power source 61 are provided on the bottom frame 34 of the first cradle 30, the overall center of gravity can be lowered, and the shaking of the base 10 can be reduced, effectively improving the smooth operation degree.

以下詳細說明本創作的動作特點，由於本創作前述實施例中，第一、二搖架30, 50的結構相似，動作亦雷同，故以第二搖架的動作為例來說明，如第4、5圖所示，由於該二左懸臂52的間距上窄下寬，且該二右懸臂54的間距上窄下寬，使得該第二搖架50前後搖擺時，本身會稍微傾斜或變化角度，能讓人感覺舒適放鬆，相較於單一吊掛點的鞦韆，其搖擺時本身的角度變化就大得多，讓人覺得刺激好玩。The action characteristics of this creation are described in detail below. Since the first and second cradle 30, 50 have similar structures and similar actions in the previous embodiment of this creation, the action of the second cradle will be described as an example, as shown in section 4. 5. As shown in FIG. 5, since the distance between the two left cantilevers 52 is narrower and lower, and the distance between the two right cantilevers 54 is narrower and lower, the second cradle 50 will slightly tilt or change its angle when swinging back and forth It can make people feel comfortable and relaxed. Compared with a swing with a single hanging point, its own angle change when swinging is much larger, which makes people feel exciting and fun.

本創作的底座之動作特點可再舉二比較例來比對說明，第一比較例如第6圖所示，若將二左懸臂52a改成間距上寬下窄的結構，其動作會完全不同，如第7圖所示，當第二搖架50a向前擺動時本身向前傾斜，而如第8圖所示，當第二搖架50a向後擺動時本身向後傾斜，讓使用者有被盪出去的感覺，較不安穩。反觀本創作的底座10，如第4圖所示，當第二搖架50向前擺動時本身向後傾斜，而如第5圖所示，當第二搖架50向後擺動時本身向前傾斜，讓使用者有被包覆住的感覺，使用時較為安穩。第二比較例則如第9圖所示，若將二左懸臂52b改成互相平行的結構，其動作也會不同，如第10圖所示，當第二搖架50b向前擺動時本身角度不變(即不會傾斜)，如第11圖所示，當第二搖架50b向後擺動時本身角度也不變(即不會傾斜)，給使用者的感覺比較機械單調，較易疲乏或無聊。The action characteristics of the base of this creation can be compared with two comparative examples. The first comparison example is shown in Figure 6. If the two left cantilever arms 52a are changed to a structure with a wide width and a narrow width, the motion will be completely different. As shown in FIG. 7, when the second cradle 50a swings forward, it tilts itself forward, and as shown in FIG. 8, when the second cradle 50a swings backwards, it tilts itself backward, allowing the user to be swayed out The feeling is less stable. In contrast, the base 10 of the present creation, as shown in FIG. 4, tilts itself backward when the second cradle 50 swings forward, and as shown in FIG. 5, tilts itself forward when the second cradle 50 swings backward, It gives the user a feeling of being covered, and it is more stable when used. In the second comparative example, as shown in FIG. 9, if the two left cantilever arms 52b are changed to be parallel to each other, their actions will also be different. As shown in FIG. 10, when the second cradle 50b swings forward, its own angle It does not change (that is, it does not tilt). As shown in Figure 11, the angle of the second cradle 50b does not change when it swings backwards (that is, it does not tilt), giving the user a more mechanical monotonous, more prone to fatigue or bored.

換言之，本創作的設計是經過許多實驗測試後所得出的最佳態樣，能讓使用者充分放鬆，甚至能解決部分失眠的問題，經過實際測試，當該第一搖架30與該第二搖架50位於擺動行程的中心點時，各懸臂36, 37, 52, 54與鉛垂線的夾角以4-12∘較佳，次佳為5-10∘，最佳則為6-8∘，前述實施例中該夾角約為7∘。基於本創作之設計精神，該底座之結構10可有其他變化設計，如該第一、二驅動裝置可採用其他具有往復驅動功能的機構，舉凡此等易於思及的變化，均應為本創作申請專利範圍所涵蓋。In other words, the design created by this experiment is the best appearance obtained after many experimental tests, which can allow users to fully relax and even solve some insomnia problems. After actual testing, when the first cradle 30 and the second When the cradle 50 is located at the center of the swing stroke, the angle between each cantilever 36, 37, 52, 54 and the vertical line is preferably 4-12∘, the next best is 5-10∘, and the best is 6-8∘, In the foregoing embodiment, the included angle is approximately 7∘. Based on the design spirit of this creation, the structure 10 of the base may have other design changes. For example, the first and second driving devices may use other mechanisms with reciprocating driving functions. Any changes that are easy to think about should be based on this creation. Covered by the scope of patent application.
