201239214 六、發明說明： 【發明所屬之技術領域】 本發明涉及一種容易組裝的樞接裝置，尤指一種適合安裝 在摩托車之車架上可轉動地連接座墊的樞接器。 【先前技術】 - 一般摩托車通常會設置有可以梅轉的一座塾，座整的下方 凹設一置物箱，可以提供摩托車騎士放置諸如安全帽等物品， 而座墊與摩托車車架之間設置一連接器，連接器包括樞設 起的第一及第二結合件，第一結合件固設於摩托車的車架上， 第二結合件固設於座墊上，使得座墊能相對摩托車的置物孝g開 啟或關閉置物箱的開口’且一般摩托車的座墊設計成需要手動 掀開，因此當摩托車騎士雙手都拿東西時，要再操作座墊 就變得有困難。 為此，遂有業者投入研發改良使用於摩托車座墊上的連接 器二其主要是在連接器上設置彈簧與阻尼裝置，使阻尼裝置與 第二結合件連動而能使摩托車的座墊開啟或關閉時具有阻尼 轉動的效果，而彈簧具有的二端分別抵接在第一及第二結合件 f ’使第二結合件能夠被彈簧抵壓而保持在開啟的位置，因此 當騎士由摩托車的主開關鎖解鎖後，彈簧就會使座墊自動開 啟並且第一結合件因為作有阻尼的轉動，因此座塾可以適當 的，度開啟。然而這種具有彈簧與阻尼器的連接器設計上，通 . 常是採用現有（市售可取得之現品）的阻尼器，連接器作設計 變更以可安裝阻尼器，因此這種具有阻尼器的連接器通常結構 較為複雜，且由於要使彈簧組裝於連接器上時，彈簧能夠抵壓 連接器的第二結合件位於開啟位置，因此第一及第二結合件樞 設在一起之前要先扭轉彈簧的兩端，然而彈簧為了要支撐座墊 能夠自動地掀開，因此彈簧的彈性力相當強，一般人手並無法 直接扭轉這種彈簧’而需要透過額外的器具扭轉彈簧後，再將 巧簧套裝於阻尼器的外側，最後再將第一及第二結合件與阻尼 器组裝在一起’導致這種具有彈簧與阻尼器的連接器組裝上相 201239214

Description of the Invention: [Technical Field] The present invention relates to a pivotal device that is easy to assemble, and more particularly to a pivotal connector that is rotatably coupled to a seat cushion of a motorcycle. [Prior Art] - A general motorcycle usually has a raft that can be turned, and a storage compartment is recessed underneath, which can provide a motorcycle rider to place items such as a helmet, and a seat cushion and a motorcycle frame. A connector is disposed between the first and second coupling members, the first coupling member is fixed on the frame of the motorcycle, and the second coupling member is fixed on the seat cushion, so that the seat cushion can be Relative to the motorcycle's storage filial g to open or close the opening of the compartment' and the general motorcycle's seat cushion is designed to be manually opened, so when the motorcyclist takes things with both hands, it is necessary to operate the seat cushion again. difficult. To this end, the industry has invested in research and development to improve the connector used on the motorcycle seat cushion. Secondly, the spring and the damping device are mainly arranged on the connector, so that the damping device and the second coupling member can be coupled to enable the seat cushion of the motorcycle. The utility model has the effect of damping rotation when opening or closing, and the spring has two ends respectively abutting on the first and second coupling members f' so that the second coupling member can be pressed by the spring to maintain the open position, so when the knight is After the main switch lock of the motorcycle is unlocked, the spring will automatically open the seat cushion and the first joint member is dampedly rotated, so that the seat can be opened appropriately. However, such a connector with a spring and a damper is generally designed to use an existing (commercially available) damper, and the connector is designed to be modified to mount a damper, so that the damper is provided. The connector is generally complicated in structure, and since the spring can press the second coupling member of the connector in the open position when the spring is assembled on the connector, the first and second coupling members are twisted before being pivoted together. The two ends of the spring, however, the spring can be automatically opened in order to support the seat cushion, so the spring force of the spring is quite strong, and the human hand cannot directly twist the spring', and the spring is required to be twisted by an additional device. Fitted on the outside of the damper and finally assembled the first and second couplings together with the damper' resulting in the assembly of the spring and damper connector assembly 201239214 when bothersome and time consuming (professional assembly of the assembly A connector may take more than five minutes), which will reduce the speed of mass production by the operator and lead to increased costs.

Therefore, the installation is extremely convenient, and the assembly efficiency can be effectively improved, and the manufacturing cost can be further reduced. Furthermore, the spring 52 can also adjust the elastic force generated by the spring 52 by rotating the ratchet 58 to the second end 56, and in detail the second object fixed to the second joint 80! The weight of 3 2 affects the amount of spring force that the spring 5 2f is to apply to the second coupling member 8 , because when the spring 52 is too elastic, the pivoting speed of the second object 13 2 may be too fast and may be injured. The user, when the spring force of the spring 52 is too weak, the spring 5 2 cannot be pivoted by the second coupling member 8 〇, so when the weight of the second coupling member 8 is heavy, the spring 5 The second end 56 of 2 can be twisted at a greater angle (the projection 7 3 is away from the second retaining wall 40 and pivoted toward the first retaining wall 38), so that the spring 52 generates sufficient support for the first joint 8 The elastic force that is pivoted at an appropriate speed, and if the second object 13 2 combined with the second coupling member 8 is lighter, the ratchet 58 is less than the second end 56 of the torsion spring 52. The angle (the bumps 7 3 are rotated away from the first retaining wall 38 toward the second retaining wall 40), so that the spring 52 generates a small elastic force to prevent the second coupling member 8 from pivoting from the closed position to the open position. The second object 13 2 moves too fast at the time of turning. The basic teachings of the present invention have been described, and many extensions and variations will be apparent to those skilled in the art. For example, the first, second, and third grooves 92'9 of the 4th member of the 4th member are: "Yes; to; 12 201239214, except in the absence of the first, second, and third grooves 92. 7xf = - the guiding tooth 48 of the coupling member 2〇, or the resistance ==, and is mounted in the two end walls 8 of the first coupling member 8 Q to hide the sound, the housing of the element 1 阻尼1 0 2 is fixed in its VU ^ body ^ 102 in the gear 118 of the linkage 114 and the guide ί (change the position of the guide tooth 48, or change the length of the linkage 11 4) and the first joint The same effect can be achieved by the housing 1 〇 2 = the connecting wall 8 2 at the position where the casing 8 collides when the opening or closing position is pivoted. Further, the damping device! 〇〇 and the guiding tooth 48 can be In the state of the missing=damping device 1 QQ and the guiding tooth 48, the difference is that when the second coupling J8 0 is pivoted from the closed position to the open position, a rapid rotation without damping force is generated.
