Abstract
一種前輪驅動自行車,包含一車架單元、一驅動單元、一轉向單元,及一座椅單元。該車架單元包括一車架本體、一前叉桿、一後叉桿,及分別樞設於該前叉桿與該後叉桿的一前輪與一後輪。該驅動單元設置於該前叉桿並能供踩踏以驅動該前輪繞自身軸線轉動而前進。該座椅單元包括一連接桿、一延伸桿、一支撐桿及一坐墊。該連接桿豎直地設置於該車架本體,能避免因為槓桿原理造成該前輪無法穩定貼合於地面,而該延伸桿是由該連接桿向後延伸,能增加該坐墊與該前輪的水平距離,因此能縮小該車架本體的長度,進而縮小該前輪驅動自行車的體積與重量。A front-wheel drive bicycle includes a frame unit, a drive unit, a steering unit, and a seat unit. The frame unit includes a frame body, a front fork rod, a rear fork rod, and a front wheel and a rear wheel pivoted on the front fork rod and the rear fork rod, respectively. The driving unit is arranged on the front fork rod and can be stepped on to drive the front wheel to rotate around its own axis to move forward. The seat unit includes a connecting rod, an extension rod, a support rod and a cushion. The connecting rod is vertically arranged on the frame body, which can prevent the front wheel from being stuck on the ground stably due to the principle of leverage, and the extension rod is extended backwards by the connecting rod, which can increase the horizontal distance between the seat cushion and the front wheel Therefore, the length of the frame body can be reduced, and the volume and weight of the front-wheel drive bicycle can be reduced.
Description
本新型是有關於一種自行車,特別是指一種前輪驅動自行車。This model relates to a bicycle, especially a front-wheel drive bicycle.
參閱圖1,中華民國發明專利第TW 101127275號申請案揭露了一種現有的前輪驅動自行車,包含一車架11、設置於該車架的一前叉桿12與一後叉桿13、分別樞設於該前叉桿12與該後叉桿13的一前輪14與一後輪15、一設置於該前叉桿12以驅動該前輪14前進的驅動單元16、一由該車架11朝後且朝上延伸的坐墊單元17,及一樞設於該車架11且位於該前輪14上方的把手桿18。Referring to Figure 1, the Republic of China Invention Patent Application No. TW 101127275 discloses an existing front-wheel-drive bicycle, which includes a
當一使用者乘坐於該座墊單元17時,該使用者的重量會對該座墊單元17施予一個朝下的作用力,而由於該車架11、該前叉桿12與該座墊單元17的配置結構,加上該坐墊單元17是由該車架11朝後且朝上延伸,因此,該作用力會因為槓桿原理而導致施加於該前輪14一個朝上的力矩,進而導致在騎乘時該前輪14無法穩定貼合於地面,造成騎乘不順暢。When a user rides on the
參閱圖2,中華民國發明專利第TW 201620771A公開號揭露的另一種現有的前輪驅動自行車,藉由將該坐墊單元17改為由該車架11朝上延伸的方式,能避免在騎乘時該前輪14無法穩定貼合於地面的情形,但該坐墊單元17與該前輪14之間需要有一段較長的水平距離才能配合踩踏時的人體工學,因此,整體而言該另一種現有的前輪驅動自行車的體積很大且重量較重,不符合近年自行車輕量化的趨勢。Referring to Figure 2, the Republic of China Invention Patent No. TW 201620771A discloses another existing front-wheel-drive bicycle. By changing the
因此,本新型的目的,即在提供一種能克服先前技術缺點的前輪驅動自行車。Therefore, the purpose of the present invention is to provide a front-wheel drive bicycle that can overcome the disadvantages of the prior art.
於是,本新型前輪驅動自行車,包含一車架單元、一驅動單元、一轉向單元,及一座椅單元。Therefore, the front-wheel drive bicycle of the present invention includes a frame unit, a drive unit, a steering unit, and a seat unit.
該車架單元包括一車架本體、分別連接於該車架本體的兩端的一前叉桿與一後叉桿,及分別樞設於該前叉桿與該後叉桿的一前輪與一後輪。該驅動單元設置於該前叉桿並能供踩踏以驅動該前輪繞自身軸線轉動而前進。該轉向單元包括一可轉動地樞設於該車架本體且位於該前輪上方的把手桿。該座椅單元包括一實質上豎直地設置於該車架本體且位於該前叉桿與該後叉桿之間的連接桿、一由該連接桿向後延伸的延伸桿、一由該延伸桿相反於該連接桿的一端朝上延伸的支撐桿,及一設置於該支撐桿上方的坐墊。The frame unit includes a frame body, a front fork rod and a rear fork rod respectively connected to both ends of the frame body, and a front wheel and a rear wheel pivoted on the front fork rod and the rear fork rod, respectively wheel. The driving unit is arranged on the front fork rod and can be stepped on to drive the front wheel to rotate around its own axis to move forward. The steering unit includes a handle rod rotatably pivoted on the frame body and located above the front wheel. The seat unit includes a connecting rod substantially vertically arranged on the frame body and located between the front fork rod and the rear fork rod, an extension rod extending backward from the connecting rod, and an extension rod extending from the extension rod. A support rod extending upwards from one end of the connecting rod, and a cushion arranged above the support rod.
本新型的功效在於:藉由設置該連接桿與該延伸桿,由於該連接桿豎直地設置於該車架本體,能避免因為槓桿原理造成該前輪無法穩定貼合於地面,而該延伸桿是由該連接桿向後延伸,因此不需要增長該車架本體的長度就能增加該坐墊與該前輪的水平距離以符合踩踏時的人體工學,所以能縮小該前輪驅動自行車的體積與重量。The effect of the present invention is that by arranging the connecting rod and the extension rod, since the connecting rod is vertically arranged on the frame body, it can avoid that the front wheel cannot be stably attached to the ground due to the principle of leverage, and the extension rod The connecting rod extends rearward, so the horizontal distance between the seat cushion and the front wheel can be increased without increasing the length of the frame body to conform to the ergonomics during pedaling, so the volume and weight of the front-wheel drive bicycle can be reduced.
