內胎Inner tube

本創作係與車輛的輪胎有關；特別是指一種內胎。This creation is related to the tires of the vehicle; in particular, an inner tube.

一般的車輛，例如機車、腳踏車，其輪胎係由一外胎與一內胎所構成，外胎用以與地面接觸，內胎供充氣以提供緩衝震動之作用。習用的內胎包括一胎管以及一充氣嘴設置於該胎管上，其中，該胎管係由一長形的橡膠管彎曲而成，於製作時，係將該胎管的兩端緣對接，並經硫化處理後，形成封閉的環狀。In general vehicles, such as locomotives and bicycles, the tires are composed of a tire casing and an inner tube. The tire casing is used to contact the ground, and the inner tube is inflated to provide a shock absorbing effect. The conventional inner tube includes a tire tube and an inflation nozzle disposed on the tire tube, wherein the tire tube is bent by an elongated rubber tube, and the two ends of the tube tube are butted at the time of manufacture. After being vulcanized, a closed loop is formed.

然而，習用的內胎之缺點在於，其僅藉由兩個端緣對接，因此，對接處的結構強度相對較弱。當內胎之橡膠逐漸老化時，容易由對接處破裂。此外，在胎管的兩端緣對接的製程中，亦很容易因為對接不良，而造成胎管漏氣的情形，使得內胎的造製良率下降。是以習用內胎之設計仍未臻完善，尚有待改進之處。However, the conventional inner tube has the disadvantage that it is only abutted by the two end edges, and therefore the structural strength of the joint is relatively weak. When the rubber of the inner tube gradually ages, it is easily broken by the joint. In addition, in the process of docking the two ends of the tire tube, it is also easy to cause the air leakage of the tire tube due to poor docking, so that the manufacturing yield of the inner tube is lowered. Therefore, the design of the conventional inner tube is still not perfect, and there is still room for improvement.

有鑑於此，本創作之目的在於提供一種內胎，可增加胎管的強度，亦提升製造良率。In view of this, the purpose of this creation is to provide an inner tube which can increase the strength of the tire tube and increase the manufacturing yield.

緣以達成上述目的，本創作提供的一種內胎，包含有一胎管與一充氣嘴，其中，該胎管包括一胎本體與一補強膠片，其中，該胎本體具有一身部及連接於該身部兩端的二連接段，各該連接段具一端緣；該補強膠片包覆該二連接段及該二端緣；該充氣嘴設置於該胎管且與該胎本體內部相通。In order to achieve the above object, the present invention provides an inner tube comprising a tire tube and a gas inflation nozzle, wherein the tire tube comprises a tire body and a reinforcing film, wherein the tire body has a body and is connected to the body The two connecting segments at the two ends each have a one end edge; the reinforcing film covers the two connecting segments and the two end edges; the inflating nozzle is disposed on the tire tube and communicates with the interior of the tire body.

本創作之效果在於，藉由補強膠片將胎本體的兩個連接段及端緣包覆而形成胎管，使補強膠片與胎本體形成大面積接觸，如此，可有效增加胎管的強度，讓內胎更為耐用，此外，亦提升內胎的製造良率。The effect of the creation is that the two connecting segments and the end edges of the tire body are covered by the reinforcing film to form a tire tube, so that the reinforcing film forms a large area contact with the tire body, so that the strength of the tire tube can be effectively increased. The inner tube is more durable and, in addition, improves the manufacturing yield of the inner tube.

為能更清楚地說明本創作，茲舉一較佳實施例並配合圖式詳細說明如後。請參圖１與圖２所示，為本創作第一較佳實施例之內胎100，包含有一胎管10與一充氣嘴16，其中：In order to explain the present invention more clearly, a preferred embodiment will be described in detail with reference to the drawings. Referring to FIG. 1 and FIG. 2, the inner tube 100 of the first preferred embodiment of the present invention comprises a tire tube 10 and an inflation nozzle 16, wherein:

該胎管10包括一胎本體12與一補強膠片14，其中，該胎本體12由長形成橡膠管彎曲而成，該胎本體12具一身部122以及連接於該身部122兩端的二連接段124，各該連接段124具有一端緣124a；該補強膠片14係包覆該二連接段124及該二端緣124a。該補強膠片14於該胎本體12的軸向上之長度L不小於該胎本體12之徑向上的外周長，藉以形成大面積的接觸。The tire tube 10 includes a tire body 12 and a reinforcing film 14 . The tire body 12 is formed by bending a long rubber tube. The tire body 12 has a body portion 122 and two connecting portions connected to the two ends of the body portion 122 . 124. Each of the connecting segments 124 has an end edge 124a. The reinforcing film 14 covers the two connecting segments 124 and the two end edges 124a. The length L of the reinforcing film 14 in the axial direction of the tire body 12 is not less than the outer circumference in the radial direction of the tire body 12, thereby forming a large-area contact.

請配合圖３，該補強膠片14結合於該胎本體12之前，為一矩形的橡膠片，將該補強膠片14包覆於該二連接段124並將該補強膠片14相對的兩側緣142對接，經過硫化處理後，該補強膠片14即與該胎本體12的該二連接段124結合，形成圖４所示之狀態。該補強膠片14的該二側緣142對接後，即形成沿該胎本體12的軸向延伸一接縫144。Referring to FIG. 3 , the reinforcing film 14 is coupled to the tire body 12 as a rectangular rubber sheet, and the reinforcing film 14 is wrapped around the two connecting segments 124 and the opposite side edges 142 of the reinforcing film 14 are butted. After the vulcanization treatment, the reinforcing film 14 is combined with the two connecting segments 124 of the tire body 12 to form the state shown in FIG. After the two side edges 142 of the reinforcing film 14 are butted, a seam 144 is formed along the axial direction of the tire body 12.

請配合圖２與圖５，而後於該補強膠片14的接縫144上開孔以貫穿該補強膠片14及該胎本體12，使該補強膠片14於接縫144處形成一通孔146，且於該補強膠片14所包覆之該胎本體12的兩端緣124a銜接處形成與該通孔146對應的一穿孔126。2 and FIG. 5, and then a hole 144 is formed in the seam 144 of the reinforcing film 14 to penetrate the reinforcing film 14 and the tire body 12, so that the reinforcing film 14 forms a through hole 146 at the seam 144, and A through hole 126 corresponding to the through hole 146 is formed at the joint of the two end edges 124a of the tire body 12 covered by the reinforcing film 14.

該充氣嘴16透過一固定膠片18設置於該胎管10，於本實施例中該固定膠片18係設置於該補強膠片14上，經硫化處理後，使該固定膠片18貼附於該接縫144上且位於對應該二端緣124a之位置。該充氣嘴16係透過該通孔146、該穿孔126而與該胎本體12內部相通。藉此，即完成圖１所示之內胎。The fixed nozzle 18 is disposed on the reinforcing film 14 in the embodiment. After the vulcanization process, the fixed film 18 is attached to the seam. 144 is located at a position corresponding to the two end edges 124a. The inflation nozzle 16 communicates with the interior of the tire body 12 through the through hole 146 and the through hole 126. Thereby, the inner tube shown in Fig. 1 is completed.

由於該補強膠片14係與該胎本體12的二連接段124有大面積的接觸結合，因此，可以有效增強該胎本體12對接處的強度，並且提升製造良率。又，該固定膠片18貼附於該補強膠片14的接縫144亦可增強該接縫144的強度。實務上，該通孔146及該穿孔126亦可不開設於該接縫144上，重要的是讓固定膠片18貼附於接縫144即可增強接縫144的強度。此外，該充氣嘴16亦可設置於該胎本體12，而不設置於補強膠片14上。Since the reinforcing film 14 has a large-area contact bond with the two connecting segments 124 of the tire body 12, the strength of the butt joint of the tire body 12 can be effectively enhanced, and the manufacturing yield can be improved. Moreover, the seam 144 of the fixed film 18 attached to the reinforcing film 14 can also enhance the strength of the seam 144. In practice, the through hole 146 and the through hole 126 may not be formed on the seam 144. It is important that the fixed film 18 is attached to the seam 144 to enhance the strength of the seam 144. In addition, the inflator 16 can also be disposed on the tire body 12 without being disposed on the reinforcing film 14.

圖６所示為本創作第二較佳實施例之內胎200，其具有大致相同於第一實施例之結構，不同的是，補強膠片20的通孔202及胎本體22的穿孔222未開設於對應該胎本體22兩端緣224a的位置，而是開設於二連接段224的其中一者。藉此，同樣可以達到與胎本體22內部連通之目的。6 shows a tube 2 of a second preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the through hole 202 of the reinforcing film 20 and the through hole 222 of the tire body 22 are not opened. Corresponding to the position of the two end edges 224a of the tire body 22, one of the two connection sections 224 is opened. Thereby, the purpose of communicating with the inside of the tire body 22 can also be achieved.

圖７所示為本創作第三較佳實施例之內胎300，其具有大致相同於第一實施例之結構，不同的是，胎本體30的兩端緣302之間相隔有一間隙S，補強膠片32上的通孔322係與該間隙S相對應。本實施例中，該間隙S的寬度不小於該通孔322的孔徑。藉此，在開孔時，只需在該補強膠片32上對應該間隙S處開設通孔322，即可使該通孔322該胎本體30內部相通。Figure 7 shows a tube 3 according to a third preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that a gap S is formed between the two end edges 302 of the tire body 30, and the reinforcing film is provided. The through hole 322 on the 32 corresponds to the gap S. In this embodiment, the width of the gap S is not less than the aperture of the through hole 322. Therefore, when the hole is opened, the through hole 322 is only required to be formed on the reinforcing film 32 corresponding to the gap S, so that the through hole 322 can communicate with the inside of the tire body 30.

據上所述，本創作之內胎藉由補強膠片將胎本體的兩個連接段及端緣包覆而形成胎管，由於補強膠片與胎本體為大面積接觸，如此，可有效增加胎管的強度，讓內胎更為耐用，此外，亦提升內胎的製造良率。According to the above description, the inner tube of the present invention is formed by reinforcing the two connecting segments and the end edges of the tire body to form a tire tube. Since the reinforcing film and the body of the tire are in contact with a large area, the tire tube can be effectively increased. The strength makes the inner tube more durable, and it also improves the manufacturing yield of the inner tube.

以上所述僅為本創作較佳可行實施例而已，舉凡應用本創作說明書及申請專利範圍所為之等效變化，理應包含在本創作之專利範圍內。The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
