M319217 八、新型說明： 【新型所屬之技術領域】 本創作係有關於一種自行車前叉避震器結構，尤其是 指除可利用鎖固使其無法產生避震效果之外，於解除鎖固 時更可達不同緩衝程度之避震效果的一種自行車前叉避 震器結構之創新設計。 【先前技術】 隨著時代的進步，人類生活水準越來越提昇，原本只 是用來做短程代步工具的自行車，卻因被提倡作為越野運 動及休閒之用，於是使用者越來越講究其是否具備有避震 之功能。 按，目前自行車前叉之避震器，大概可分兩種：一種 係為可鎖固式油壓桿，此種避震器之油壓桿在不需要有避 震功能時，雖然可將油壓桿鎖固即可達到完全沒有避震功 能，然而當油壓桿沒有被鎖固時，卻因其只具有固定的回 彈力，因此不管路況如何，其軟硬程度的避震效果都是一 樣，所以其避震效果相當不好；另一種則是可調式油壓 桿，此種避震器之油壓桿雖然可以依需要而被調整以應付 不同路況，來形成不同之回彈力，達到不同軟硬程度的避 震效果，但是卻因無法被鎖固，所以當希望不要有避震功 能時卻無法達到。 緣是，創作人有鑑於此，秉持多年相關行業實際之設 計與製造經驗，提供一種創新的自行車前叉避震器結構， 以期完全改善現有之所有缺失者。 【新型内容】 M319217 =創作係有’―種自行車前叉避震器結構，包 π έ士人、一插設結合於缸體上端之第一活塞桿、一活動批 ===之第二:塞桿、分別固設結合於第~ 干表鳊之弟一、二控制座、一油路 制座之底部係與缸體固設結合 检 油路活塞相 路活突口 思第二活塞桿滑移於缸體内，俾使$ 路活基與弟一控制座分別形成第一、三、三液壓室；灸冷 該缸體，具有一中空容室；M319217 VIII. New description: [New technical field] This creation is about a bicycle front fork shock absorber structure, especially when it can be used to lock the suspension to prevent the shock effect. An innovative design of a bicycle front fork suspension structure that achieves a shock-absorbing effect with different cushioning levels. [Prior Art] With the advancement of the times, the standard of human life is getting higher and higher. Originally, it was only used as a short-distance travel tool. However, because it was promoted as a cross-country sport and leisure, users are more and more concerned about whether it is It has the function of shock absorber. According to the current shock absorbers for bicycle front forks, there are probably two types: one is a lockable hydraulic rod, and the hydraulic rod of such a shock absorber can be used when there is no need for a shock absorber function. When the pressure bar is locked, it can achieve no shock absorber function. However, when the hydraulic pressure rod is not locked, it has only a fixed resilience. Therefore, the effect of the soft and hard shock is the same. Therefore, the shock absorber effect is quite bad; the other is the adjustable hydraulic rod. Although the hydraulic rod of the shock absorber can be adjusted to meet different road conditions as needed, different resilience can be formed to achieve different Soft and hard shock absorber effect, but because it can not be locked, it is impossible to achieve when you do not want to have a shock absorber function. The reason is that the creators have provided an innovative bicycle front fork shock absorber structure with a view to the design and manufacturing experience of the relevant industry for many years, with a view to completely improving all the existing missing.

The second adjusting rod 31) is adjusted downward to drive the second control tip (3), so that the second control tip (3), the taper portion (321) is disengaged from the second control seat (5) and the upper through hole (523) Lower 'edge cone (10) Γ), at this time, when the second piston rod (3) is pressed upwards, • will link the second control seat (5) and the oil circuit The plug (6) - moves up, shrinks the third hydraulic chamber (12), and forces the hydraulic oil in the second hydraulic chamber (12) to flow through the through hole (413) of the lower portion of the first control seat (4). Simultaneously in a hydraulic chamber (n), when the second piston rod (3) is pressed upwards to a considerable extent and the second hydraulic chamber (12) and the first hydraulic chamber (丨^ almost reach saturation, the second hydraulic pressure to ( 12) The hydraulic oil will flow into the third liquid chamber (13) through two pipes, one of which is through the second control seat (5) through the second control seat (5) through the second control seat (5) The oil passage side passage (5221) flows into the third hydraulic chamber (13), and the second is flowed downward by a plurality of oil passage holes (63) of the oil passage piston (6) and is forced to be sleeved: in the second control seat (5) The notch throttle piece (55) and the throttle piece (54) of the neck portion (51) are pressed down the telescopic elastic member (53) and flow into the third hydraulic chamber (13) to achieve a softer long stroke buffer shock absorber. The effect; in addition, when the second live plug (3) is forced downward, the second control seat (5) and the oil passage piston (6) are moved together to make the third hydraulic chamber (13) Shrink and force The hydraulic oil in the third hydraulic chamber (13) flows into the second hydraulic chamber (12) through two pipes, and the second control seat (5221) passes through the second control seat via the oil passage side passage (5221) of the second control seat (5) ( 5) The upper through hole (523) flows into the second hydraulic chamber (12), and the second portion is sleeved at the notch of the notched throttle piece (55) of the neck (51) of the second control seat (5). The oil passage holes (63) of the oil passage piston (6) flow into the second hydraulic chamber (12) to achieve a soft buffering effect; and when a hard short stroke buffer suspension effect is to be produced, please refer to 11 M319217 In the eightyth figure, the eighth and ninth figures are the sides of the creation that are adjusted to be hard buffers. The tenth and tenth drawings are all the posts of the bureau that are adjusted to be hard buffer shock absorbers. The schematic diagram can adjust the second adjusting rod (31) of the third piston rod (3) upward to drive the second control tip (32), so that the taper portion (321) of the second control tip (32) corresponds to the sealing portion. The second control seat (5) has a tapered opening (5231) at the lower edge of the upper through hole (523). At this time, when the second piston rod (3) is pressed upward, the second control seat is interlocked ( 5) and the oil passage piston (6) moves upward to reduce the second hydraulic chamber (12), and forces the hydraulic oil in the second hydraulic pressure to (12) to flow through the lower passage hole (413) of the first control seat. In the first hydraulic chamber (11), at the same time, when the second piston rod (3) is pressed upward to a considerable extent and the second hydraulic chamber (12) and the first hydraulic chamber (11) are almost saturated, the second hydraulic chamber The hydraulic oil in (12) can only flow down through the oil passage holes (63) of the oil passage piston (6) and force the notched throttle piece sleeved on the neck (51) of the second control seat (5) ( 55) and the throttle piece (54) presses the telescopic elastic member (53) downward and flows into the third hydraulic chamber (13), so that only a hard short stroke shock absorber effect can be achieved; further, when the second piston When the rod (3) is pressed downward, the second control seat (5) and the oil passage piston (6) are moved together to lower the third hydraulic chamber (13) and force the third hydraulic chamber (13). The hydraulic oil inside can only pass through the oil passage holes (63) of the oil passage piston (6) at the notch of the notch throttle piece (55) of the neck portion (51) of the second control seat (5). 〇2 into the second hydraulic chamber), the harder cushioning can only achieve short stroke of the shock effect. From the above, the structure and implementation of the creation can be seen that the creation has the following advantages: I The bicycle front fork suspension structure can adjust the adjustment lever of the first piston rod downwards. Make the younger brother control the taper of the tip to seal the result
