M304344 八、新型說明： 【新型所屬之技術領域】 本創作係有關一種具避震效果之傳動機構，尤指一種在 傳動機構内部加設避震單元之設計者。 【先前技術】 按，第一圖所示，係習用一種跑步機（60)之外觀圖，其底 座（61)上裝設有一架體（62)，且於架體（62)上設有跑步板（63) 及跑步帶（64)，一般為了提昇使用者之舒適性，會令跑步板 (63)具有避震效果，而常見之避震設計，係於跑步板（63)與架 體（61)間增設避震構件（如緩衝墊塊），或於跑步板（63)表面 鋪設軟墊層（圖未示），讓該跑步帶（64)具缓衝效果。然查，此 種方式不是結構欠缺整體性，就是避震效果不佳；究其原因， 乃在於該架體（62)及跑步板（63)係為剛性，縱使在其上設有 緩衝墊塊或軟墊層，而當使用者在跑步帶（64)上踩踏時，則跑 步板（63)對於腳部之反作用力仍然很大，除了感覺不舒服外， 長時間使用亦容易對腳部造成運動傷害。 次按，前揭架體（62)與底座（61)之間，經常需使用到一個 具有升降功能之傳動機構，來調整架體（6 2)的傾斜角度（仰 角），俾適合不同使用者之需求。而此種傳動機構（或稱升降 馬達）需配合各種不同跑步機之空間及頂升結構來裝設，第 二圖（A)、（B)所示，係顯示該傳動機構（70)裝設的一種實施例， 其一端樞接在該底座（61)之凸耳（611)上，而另一端則樞接在 一驅動柄（65)的致動端（651 )，當馬達（71)拉動傳動桿（72)收 縮時，帶動該驅動柄（65)以樞軸端（652)偏轉，進而迫使與架 M304344 體（62)連接之頂桿（66)揚起，利用拉（PULL)的方式得以調整 架體（62)(即包含跑步板）之仰角（Θ)。另，第三圖（A)、（B)所示 係該傳動桿（72)與驅動柄（65’）之樞接位置不同於前揭實施 例，其係利用推（PUSH)的方式帶動該致動端（651)，進而調整 該架體（62)之仰角（Θ)。 由以上說明得知，調整架體（62)的仰角（Θ)可依跑步機之 頂升結構而有拉（PULL)及推（PUSH)等方式。惟無論是那一 種方式，該傳動機構（70)整體亦屬剛性結構，對於該架體 (62)之避震效果，並無任何幫忙，且因為聯結有傳動機構（70)， 使得架體（62)無法另外單獨增設緩衝機構，致使此類型跑步 機之避震效果始終無法改善。 【新型内容】 緣是，本創作之主要目的，係欲解決先前技術結構欠缺 整體性或避震效果不佳之問題，並巧妙地將傳動機構設計成 具有避震功能，進而使得與其聯結之架體在承受運動者之重 量時，依選定之拉或推的方式，而具有緩衝效能，使得使用時 舒適，並可降低運動傷害之功效。 為達上述功效，本創作之結構特徵，係包括有： 一傳動單元，將傳動齒輪組設置於一殼體内部； 一馬達，設置於該殼體外部，提供該傳動齒輪組所需之 動力； 一傳動桿，組接於該傳動齒輪組以形成動力傳遞關係； 一避震單元，將一固定套管相對該傳動桿之内端，而設 置於該殼體外部，並於該固定套管内部罩置一避震彈簧，且 以一伸縮桿致動該避震彈簧；以及 M304344 一調整單元，設置該傳動桿與避震單元之間者。 【實施方式】 首先，請參閱第四圖〜第六圖（A)、（B)所示，本創作第一 實施例包含有： 一傳動單元（10)，係將一傳動齒輪組（丨丨）設置於一殼體 (12)内部； 一馬達（20)，設置於該殼體（12)外部，提供該傳動齒輪組 (11)所需之動力； 一傳動桿（30)，組接於該傳動齒輪組（11)，以形成動力傳 遞關係，本實施例中之傳動桿(30)係為伸縮螺桿態樣，亦即該 馬達⑽帶動該傳動齒輪組⑴)轉動，再由傳動齒輪組（11)其 中顆齒輪的内部螺牙來驅動該傳動桿（3〇)軸向伸縮位移， 此為一般機械傳動原理，容不贅述。 一避震單元（40)，將一固定套管（41)相對於該傳動桿（3〇) 之内端，而設置於該殼體（12)外部，並於該固定套管⑼内部 罩置避震彈；（42)，且以一伸縮桿⑷）致動該避震彈簧 (42)，本實施财，該伸縮桿（43)係採外錢動，即該伸縮桿 (43ϋ側端鎖定一凸緣片（45)，另固定套管（41)外端面鎖定 :環蓋(44)，用以固定内部之避震彈簧（42)。第六圖⑻係顯 不該伸縮桿（43)外伸之情形，據以形成-拉伸（PULL)避震之 態樣，以此結構可運用作為第二圖㈧、⑻習用跑步機之傳 :構，如此，除可調整該架體㈣之仰角⑼，更可提供該架 —$及其上之跑步板一緩衝避震功能。 "閱第七圖及第八圖⑷、⑻所示，本創作第二實施 例所揭示之特徵大致相同於第-實施例，其相同元件以同-M304344 VIII. New description: [New technical field] This creation is related to a transmission mechanism with suspension effect, especially a designer who adds a suspension unit inside the transmission mechanism. [Prior Art] According to the first figure, an appearance view of a treadmill (60) is adopted, and a base (61) is mounted on the base (61), and running is provided on the frame body (62). The plate (63) and the running belt (64) are generally used to improve the comfort of the user, which will make the running board (63) have a shock-absorbing effect, and the common shock-absorbing design is attached to the running board (63) and the frame ( 61) Add a shock-absorbing member (such as a cushion block) or lay a cushion layer (not shown) on the surface of the running board (63) to make the running belt (64) have a cushioning effect. However, this method is not a structural lack of integrity, or a poor suspension effect; the reason is that the frame (62) and the running board (63) are rigid, even if a cushion is provided thereon. Or a cushion layer, and when the user steps on the running belt (64), the reaction force of the running board (63) on the foot is still large, and in addition to feeling uncomfortable, it is easy to cause the foot for a long time. Sports injuries. After pressing, the front lifting body (62) and the base (61) often need to use a transmission mechanism with lifting function to adjust the tilt angle (elevation angle) of the frame body (6 2), which is suitable for different users. Demand. The transmission mechanism (or lifting motor) needs to be installed in accordance with the space and jacking structure of various treadmills. The second diagram (A) and (B) show that the transmission mechanism (70) is installed. In one embodiment, one end is pivotally connected to the lug (611) of the base (61), and the other end is pivotally connected to an actuating end (651) of the driving handle (65) when the motor (71) is pulled. When the transmission rod (72) is contracted, the driving handle (65) is deflected by the pivot end (652), thereby forcing the jack (66) connected to the frame M62344 body (62) to be raised, using a pull (PULL) manner. The elevation angle (Θ) of the frame (62) (ie including the running board) can be adjusted. In addition, the third figure (A), (B) shows that the pivotal position of the transmission rod (72) and the driving handle (65') is different from the previous embodiment, which is driven by the push (PUSH) method. The actuation end (651), in turn, adjusts the elevation angle (Θ) of the frame (62). As apparent from the above description, the elevation angle (Θ) of the adjustment frame body (62) can be pulled (PULL) and pushed (PUSH) depending on the jacking structure of the treadmill. In either case, the transmission mechanism (70) is also a rigid structure as a whole, and there is no help for the suspension effect of the frame body (62), and because the transmission mechanism (70) is coupled, the frame body ( 62) It is not possible to add a separate buffer mechanism, so that the suspension effect of this type of treadmill can never be improved. [New content] The main purpose of this creation is to solve the problem of lack of integrity or suspension effect of the prior art structure, and skillfully design the transmission mechanism to have a shock-absorbing function, thereby enabling the frame to be coupled with it. When it bears the weight of the athlete, it has the cushioning effect according to the selected pulling or pushing method, which makes it comfortable to use and can reduce the effect of sports injury.
