Description
本案是關於自行車之車首豎管的緩衝避震結構。 This case is about the buffer suspension structure of the first standpipe of the bicycle.
無車首緩衝避震或此功能未能有效發揮的自行車，於行進時將會使地面施予前輪的反作用力通過前叉、車首豎管傳遞至把手，造成把手震動。以往，通過設置在前叉的一個或一對(左右各一)以壓縮彈簧為主的緩衝組件來減少前叉震動並試圖緩和把手的震動，但實際上無法達到良好的把手減震效果。因此，若要具體的減少自行車把手震動問題，緩衝避震設計應實現在車首豎管。 A bicycle without a head buffer or a bicycle that does not function effectively will cause the reaction force of the front wheel to be transmitted to the handle through the front fork and the head stand when the vehicle is traveling, causing the handle to vibrate. In the past, by providing one or a pair of front forks (one left and the right) with a compression spring-based cushioning assembly to reduce the front fork vibration and attempt to alleviate the vibration of the handle, in reality, a good handle damping effect cannot be achieved. Therefore, in order to specifically reduce the vibration of the bicycle handlebar, the buffer suspension design should be realized in the headstock.

本創作的功效：自行車行進中，從地面施予前輪的反作用力(由下而上的軸向震動力)，由該第一彈簧和該第二彈簧分段吸收，具體的減少從前叉傳遞給該立管和該豎管的震動，從而使自行車的把手震動程度得以減輕。 The effect of the creation: during the bicycle travel, the reaction force of the front wheel (the bottom-up axial vibration force) is applied from the ground, and is absorbed by the first spring and the second spring, and the specific reduction is transmitted from the front fork to The riser and the riser vibrate, thereby reducing the vibration of the handle of the bicycle.
當自行車的騎者施加較大的下壓力量於自行車的把手時，與該把手連接的該豎管承受由上而下的軸向力量，此一力量壓縮該第一彈簧和該第二彈簧，該第一彈簧和第二彈簧分段吸收該力量，減少下壓力量通過該前叉立管傳遞至該前叉和前輪，據以使前叉和前輪保持上下活動的自由性，不因加重於把手的力量而致前叉和前輪變得難以操控。 When the rider of the bicycle applies a large amount of depression to the handle of the bicycle, the standpipe connected to the handle receives an axial force from top to bottom, the force compressing the first spring and the second spring, The first spring and the second spring segment absorb the force, and the amount of downward pressure is transmitted to the front fork and the front wheel through the front fork riser, so that the front fork and the front wheel are kept free from movement up and down, without being aggravated by The strength of the handle makes the front fork and front wheel difficult to handle.
該第一彈簧和該第二彈簧是內藏於該套管和該立管中，避免外部塵土或污垢卡積，且被該套管和該立管所保護，不致受到外力撞擊，確保該第一彈簧和該第二彈簧的彈性活動得以確實發揮，並延長使用壽命。 The first spring and the second spring are embedded in the sleeve and the riser to prevent external dust or dirt from accumulating, and are protected by the sleeve and the riser, so as not to be impacted by external force, ensuring the first spring The elastic movement of a spring and the second spring is sure to be exerted and the service life is extended.
基於該立管與該套管之間彼此以多邊形區段結合，以及該套管穿設固定於一自行車的前叉立管中，因此該豎管之轉向運動可通過該立管、套管而同步驅動該前叉立管及前叉轉向，從而控制自行車的前輪轉向，該豎管對該前叉的傳動確實。 Based on the fact that the riser and the sleeve are combined with each other in a polygonal section, and the sleeve is threaded and fixed in a front fork riser of a bicycle, the steering movement of the riser can pass through the riser and the sleeve The front fork riser and the front fork are synchronously driven to control the front wheel steering of the bicycle, and the standpipe is sure to drive the front fork.
該立管及該套管以多邊形區段穿套配搭，可定位該豎管，使自行車的把手及車首不至於任意偏擺。 The riser and the sleeve are matched by a polygonal section, and the vertical tube can be positioned so that the handle and the front of the bicycle are not arbitrarily biased.

The through hole 13 is disposed in the through hole 13 of the sleeve end seat 12, and the sleeve end 12 and the threaded hole 32 of the inner rod 30 are locked by a screw member 33 to fix the inner rod 30 to the sleeve end seat 12.
所述之第二彈簧35，設於該立管20內部，該第二彈簧35的底端 抵頂該內桿30該環狀支托部31。 The second spring 35 is disposed inside the riser 20, and the bottom end of the second spring 35 The annular support portion 31 is abutted against the inner rod 30.
所述之豎管40(或稱龍頭、把立)，其第一端設一立管束緊環41，其第二端設一把手束緊環42，所述的立管束緊環41和把手束緊環42均為習知結構，在此不多加贅述；該把手束緊環用42以結合一自行車把手(圖未示)；該立管束緊環41的內部通過一緩衝襯套43而束緊結合於該立管20的外部。 The standpipe 40 (or faucet, stem) has a riser tightening ring 41 at a first end and a handle tightening ring 42 at a second end thereof. The riser tightening ring 41 and the handle are tightened. The ring 42 is a conventional structure, which is not described here; the handle is tightened with a ring 42 for engaging a bicycle handle (not shown); the inside of the riser tightening ring 41 is tightly coupled by a buffer bushing 43. Outside the riser 20.
所述之端蓋45，通過螺紋線結合於該立管20的頂端，該端蓋45擋止該立管束緊環41之上，且壓制該第二彈簧35的頂端。 The end cap 45 is coupled to the top end of the riser 20 by a threaded wire that blocks the riser collar 41 and presses the top end of the second spring 35.
已知，自行車的前叉50以前叉立管51穿設於自行車車架的前管55中，且在前管55的上端及下端各配設一車頭碗組52，使該前叉立管51可於該前管55中自由旋轉。 It is known that the front fork 50 of the bicycle is disposed in the front tube 55 of the bicycle frame, and a front head group 52 is disposed at the upper end and the lower end of the front tube 55, so that the front fork riser 51 is provided. It can rotate freely in the front tube 55.
本創作的豎管緩衝避震結構以該套管10穿設於該前叉立管51中，通過一束於該前叉立管51外部的束緊扣環53，迫使該套管10與該前叉立管51為緊迫結合關係。在該套管10的管端與該束緊扣環53之間可視情況加設一個或數個墊圈54。據此，該自行車把手(圖未示)左右轉向，該豎管40帶動該立管20轉動，基於該立管20與該套管10之間彼此以多邊形區段11,21結合，因此該立管20驅動該套管10同步轉動，該套管10則驅動該前叉立管51及前叉50轉向，從而控制自行車的前輪(圖未示)轉向。並且該立管20及該套管10以多邊形區段穿套11,21配搭，可定位該豎管40，使自行車的把手及車首不至於任意偏擺。 The vertical tube buffer suspension structure of the present invention is inserted into the front fork riser 51 by the sleeve 10, and the sleeve 10 is forced by a bundle of buckles 53 outside the front fork riser 51. The front fork riser 51 is in a tight coupling relationship. One or more washers 54 may optionally be added between the tube end of the sleeve 10 and the tightening ring 53. Accordingly, the bicycle handle (not shown) is turned left and right, and the standpipe 40 drives the riser 20 to rotate. Based on the standpipe 20 and the sleeve 10, the polygonal sections 11, 21 are coupled to each other, so The tube 20 drives the sleeve 10 to rotate synchronously, and the sleeve 10 drives the front fork riser 51 and the front fork 50 to turn, thereby controlling the steering of the front wheel (not shown) of the bicycle. And the riser 20 and the sleeve 10 are matched by the polygonal section through the sleeves 11, 21, and the vertical tube 40 can be positioned so that the handle and the front of the bicycle are not arbitrarily biased.
自行車行進中，從地面施予前輪的反作用力(由下而上的震動力)傳遞至該前叉50，該前叉立管51所承受的上下震動使該套管10、該套管端 座12、及該內桿30產生上下位移，該第一彈簧15和第二彈簧35吸收該軸向的震動力，具體的減少了從該前叉50傳遞給該立管20和該豎管40的震動，從而使自行車的把手震動程度得以減輕。 While the bicycle is traveling, the reaction force (the bottom-up vibration force) applied to the front wheel from the ground is transmitted to the front fork 50, and the up-and-down vibration of the front fork riser 51 causes the sleeve 10 and the sleeve end The seat 12 and the inner rod 30 are displaced up and down, and the first spring 15 and the second spring 35 absorb the vibration force of the axial direction, specifically reducing the transmission from the front fork 50 to the riser 20 and the standpipe 40. The vibration of the bicycle can reduce the vibration of the handle of the bicycle.
再者，當自行車的騎者騎乘重心往前移，例如向前壓曲身體或者是站立騎乘的情況中，騎車的雙手會施加較大的下壓力量於把手，因此該豎管40承受由上而下的較大力量，此一力量使該立管20及該立管端座22在該套管10中往下移動，壓縮該第一彈簧15和該第二彈簧35，該第一彈簧15和第二彈簧35吸收該力量，減少下壓力量通過該前叉立管51傳遞至該前叉50和前輪，據以使前叉50和前輪保持上下活動的自由性，不因加重於把手的力量而致前叉50和前輪變得難以操控。 Furthermore, when the rider of the bicycle rides the center of gravity forward, for example, in the case of bending the body forward or standing and riding, the hands of the bicycle exert a large amount of downward pressure on the handle, so the standpipe 40 is subjected to a large force from top to bottom, the force moving the riser 20 and the riser end seat 22 downward in the sleeve 10, compressing the first spring 15 and the second spring 35, The first spring 15 and the second spring 35 absorb the force, and the amount of downward pressure is transmitted to the front fork 50 and the front wheel through the front fork riser 51, so that the front fork 50 and the front wheel are kept free from movement up and down. The weight of the handle is increased and the front fork 50 and the front wheel become difficult to handle.
