201020154 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種機車。 【先前技術】 自先前以來，於如小輪機踏車（scooter)型車輛等、包含 被車架可擺動地支持之引擎單元（engine unit)的機車中， 已知有於車體之後部設有牌照托架（licence plate braeket) 者。於下述專利文獻1中，如圖18所示，揭示有自車體之 後部朝後方斜下方延伸之牌照托架101、以及覆蓋後輪1〇2 之上方之後擋泥板（rear fender) 103。再者，圖19係自車輛 之後方觀察之圖。 牌照托架10 1具有支持牌照（licence plate)之功能以及避 免由後輪102所捲起之水或泥等濺至乘員身上之功能、即 所謂擋泥功能，且呈上下方向較長之形狀。自先前以來， 一直認為於注重擋泥功能之機車中，較理想的是使牌照托 架大型化。具體而言，一直認為較好的是牌照托架之上下 方向之長度較長，且較好的是牌照托架之車輛寬度方向之 長度亦較長。 [專利文獻1 ]臺灣專利第2425 15號公報 【發明内容】 [發明所欲解決之問題] 然而，若牌照托架101較大，則存在機車之後部整體大 型化之問題。特別是於包含被車架可擺動地支持之引擎單 兀（以下稱為單元擺動（unit swing)式引擎單元）之機車中， 136684.doc 201020154 後擋泥板103會與後輪i〇2—同擺動。因此，於後輪i〇2、 後擋泥板103與牌照拕架丨〇1之間需要某種程度較大之空 間’以避免該等相接觸。因此，需要將牌照托架1〇1配置 於足夠後方，以避開後輪102及後擋泥板103❶然而，為了 於距離後輪102足夠之位置確保擋泥功能，牌照托架1〇1會 於上下方向上增至更大。因此，無法避免牌照托架1〇1增 大，機車之後部容易大型化。 另一方面，若注重小型化而僅使牌照托架1〇1小型化， 則難以發揮充分之擋泥性能。如此，先前於包含單元擺動 式引擎單兀之機車中，被認為難以使擋泥性能與後部之小 型化以高標準並存。 本發明係鑒於上述問題點而完成者，其目的係於包含單 元擺動式引擎單元之機車中，使後部之擔泥性能與小型化 以南標準並存。 [解決問題之技術手段] 本發明之機車包含：車架，其係沿著車輛之前後方向超

夠使後部之擋泥性能與小型化以高標準並存。 φ 【實施方式】 <實施形態之構成> ‘如圖1所示，本實施形態之機車係速克達型車輛丨。其 中，本發明之機車並不限定於速克達型車輛丨，亦可為其 他機車。於以下說明中，前、後、左、右之方向分別係指 由乘坐速克達型車輛1之乘員所觀察到之前、後 '左、右 之方向。圖1中之符號Fr表示前方。 速克達型車輛1包含車架2。車架2包含：前管（headpipe) 2a

端40c位於較連結上端4〇a與下端40b之線L6更後方之位 置。圖8中之點P1表示線L4與線L5之交點。再者，突部40 之後端40c可不必為點狀。換言之，突部4〇之後側部分可 不必形成為銳角。例如’如圖16(a)所示，突部40之後端 40c亦可於上下方向上具有寬度。即，突部4〇之後端40c亦 可形成為線狀。又，自側面觀察，突部40之後側部分既可 形成為直線狀，亦可如圖16(b)所示形成為曲線狀。 圖17係包含前蓋體30之突部40之後端40c之水平剖面的 圖。如圖1 7所示，突部40之後端40c位於後側蓋3 1中車輛 寬度方向（圖17之上下方向）之最外側。 如圖3所示，自正面觀察，突部40之後端40c成為位於前 蓋體30中車輛寬度方向之最外側的部分。突部40之後端 4〇c位於較後側蓋3 1之上侧之後端3 1 a更靠車輛寬度方向之 外側的位置。再者，於圖3中，直線L8表示通過後側蓋3 1 之後端31a之垂直線。突部40之後端40c位於較該直線L8更 外側之位置。又，如圖9所示，自側面觀察，突部40之後 端40c位於較連結後側蓋3 1之上側之後端3 1 a與下側之後端 31b的線L7更前方之位置。又，突部40之後端40c位於較後 側蓋31之上側之後端31a與下側之後端31b的上下方向之中 間位置3 lc更上方之位置。突部40之後端40c位於較前輪6 之後端6e更後方之位置。

蓋7包含突出部71，當以沿著車輛寬度方向切割之剖面進 ^ 行觀察時，該突出部71朝車輛寬度方向（圖11之左右側向） 突出。如圖1所示，將側蓋7之突出部71沿著車輛前後方向 加以連結而形成之線，自車輛之側面觀察呈後部上升狀傾 斜。再者，突出部71所連結而形成之線可不必為清晰之 線。如本實施形態，於突出部71朝向車輛寬度方向之外側 尖突之情形時，將出現清晰之線。然而，於突出部71並未 尖突之情形時，例如於平緩彎曲之情形等時，則不會出現 清晰之線。即便於此情形時，亦可聯想到將位於車輛寬度 • 方向之最外側之部分沿著車輛前後方向加以連結之線，^ 線亦可視為將突出部71沿著前後方向加以連結而形成之 • 線。又，將突出部71沿著車輛前後方向加以連結而形成之 線亦可於上下方向上具有某種程度之寬度。 如圖1所示，收納箱18之下部18a自側蓋7之下緣乃朝下 方突出。又，電池盒丨1之一部分亦自側蓋7之下緣73朝下 方露出。再者，收納箱18或電池盒丨丨為速克達型車輛1之 零件之一例，其他零件之一部分或全部亦可自側蓋7之下 緣73朝下方露出。作為其他零件，亦可考慮例如後緩衝單 136684.doc •15- 201020154 元9、燃料箱等…車架2之一部分亦可自側蓋7之下緣 73朝下方露出。如此’對自側蓋7之下緣73朝下方露出之 零件或部分並無特別限定’亦可為例如車架或上側後緩衝 托架12等。 如圖4所示，於左側之側蓋7之後端部與右側之側蓋了之 後端部之間配置有尾燈…於尾㈣之下方設有反射板 87 ° 速克達型車輛1包含支持牌照8〇之牌照托架8。牌照托架 8以位於較尾燈1()更下方之位置的方式而被車架2所支持。 牌照托架8既可與車架2直接接合，亦可直接安裝於車架2 上。又，亦可經由托架等安裝構件而間接安装。牌照托架 8包含配置於尾燈10之下方之後部82、以及自後部^之左 側及右側朝前方延伸之左側及右側之側部81。後部Μ與兩 側部81—體化，後部82連接兩側部81。如圖$所示，自平 面觀察，左側及右侧之侧部81自後部82朝向前方呈逐漸擴 展狀延伸。再者，如圖12所示，牌照8()安裝於後部Μ。 如圖1所示’側部81沿著側蓋7之下緣73延伸。側部以覆 蓋自側蓋7之下緣73朝下方露出之收納箱18之一部分，即 收納箱18之下部18a之後側部分。又，側部8ι亦覆蓋自側 蓋7之下緣73朝下方露出之電池盒"之一部分。再者，側 部81所覆蓋纟並不限於速克達型車輛1之零件，亦可為車 架2之一部分。 如圖12所示’自側面觀察，後緩衝單元9之上側後緩衝 托架12之支持部分9&位於較牌照托架8之侧部更下方之 I36684.doc -16 - 201020154 位置。因此，上述支持部分9a朝側方露出。再者，後緩衝 單元9之支持部分9a位於較下述後擋泥板54更上方之位 置。 如圖12所示’牌照托架8之車輛上下方向之長度!^短於 車輛前後方向之長度h2。又，牌照托架8之車輛上下方向 之長度hi短於車輛寬度方向之長度h3(參照圖5)。如圖12所 示’該牌照托架8以如下方式而形成，即，當安裝有牌照 80時，牌照托架8之後部82之下端82a位於較牌照80之下端 φ 80a更上方之位置。再者’牌照托架8之下端82a亦成為牌 照托架8之後端。該牌照托架8之後端8 2 a位於較尾燈1 〇之 後端10a更前方之位置。 於牌照托架8之側部81安裝有後閃光器84 〇即，左側及 右側之後閃光器（rear flasher)84分別被左側及右側之牌照 托架8所支持。後閃光器84自牌照托架8之側部81朝車輛寬 度方向之外側突出。如圖5所示，自平面觀察’後閃光器 ❿ 84以至少其一部分被側蓋7之突出部71所遮蓋之方式而配 置於與突出部71重疊之位置。 又’如圖12所示’自側面觀察，後閃光器84配置於較車 體之後側之輪廓線更前方之位置。換言之，後閃光器84配 置於較由尾燈10與牌照托架8所形成之後側之輪廓線更前 方之位置。詳細而言，後閃光器84之後端84a位於較上述 輪廓線更前方之位置。再者，於本實施形態中，牌照托架 8包含支持照射牌照80之燈（未圖示）之照明部83。照明部83 與後部82形成為—體，且自後部82之上部朝後方突出。但 136684.doc -17- 201020154 是，未必需要照明部83，亦可例如利用尾燈丨〇之光來照射 牌照80。因此，如圖13所示，可視為由尾燈丨〇、以及牌照 托架8之中除去照明部83以外之部分，來形成車體之後側 之輪廓線BL(圖13中之粗線）。自側面觀察，後閃光器84之 後端84a位於較上述輪廓線bl更前方之位置。 如圖13所示，自侧面觀察，尾燈10與牌照托架8之後部 82形成自特定之穀間位置85朝後方斜上方向及後方斜下方 向延伸之大致橫V字型。後閃光器84之車輛前後方向之中 間位置84m位於較穀間位置85更前方之位置。如圖5所示， 自平面觀察，後閃光器84位於較位於側蓋7中車韩寬度方 向之最外侧之外端72更靠車輛寬度方向之内侧之位置。換 言之，閃光器84之外端84b位於較通過側蓋7之外端72且沿 著車輛前後方向延伸之線L9更靠車輛寬度方向之内侧之位 置。 如圖12所示，牌照托架8之側部81位於較尾燈1 〇更前方 之位置。後閃光器84以位於較尾燈1〇更前方之位置的方式 而安裝於側部81。更詳細而言’後閃光器84之後端84a位 於較尾燈10之後端10a更前方之位置。如圖14所示，於牌 照托架8之側部8 1形成有凹部81

支持部86，以將後閃光器84支持於該支持部86上。再者， 即便於此情形時，後閃光器84亦以自平面觀察其—部分被 側蓋7之突出部71所遮蓋之方式，而配置於與突出部71重 疊之位置。 如圖1所示，於後輪53之上方設有後擋泥板54。後播泥 板54於前後方向上，自較後輪53之中心53c更前方之位置 朝較後輪53之後端之位置τ更後方延伸。具體而言，後擒 泥板54自引擎單元5之曲軸箱（未圖示）之後方附近之位置起 朝後方延伸，而朝較後輪53之後端之位置T更後方延伸。 後擋泥板54形成為順應後輪53之形狀之形狀。即，自側面 觀察’後擋泥板54形成為大致圓弧狀。 如圖4所示，後擋泥板54包含··擋泥板本體54&，其覆蓋 後輪53之上方及左右兩方向之一部分；側片部54b，其自 擔泥板本體54a朝左側及右側突出；以及下片部54c，其自

如上所述，本實施形態之速克達型車輛1如圖1所示’包 136684.doc .19- 201020154 含牌照托架8與後擋泥板54。牌照托架8包含左側及右側之 側部81、以及支持牌照80之後部82 »後部82連接左側及右 側之侧部81。各側部81沿著側蓋7之下緣73之一部分而配 置。又，各側部81覆蓋自側面觀察自側蓋7之下緣73朝下 方露出之收納箱18之一部分及電池盒11。後擋泥板54延伸 至較後輪53之後端之位置T更後方之位置為止。又，後擋 泥板54之後部之下端54d位於較牌照托架8之後部82之下端 82a更下方之位置。 根據本實施形態，由於後擋泥板54充分延伸至後方為 ❿ 止’因此可充分覆蓋後輪53。由此，後擋泥板54將發揮充 分之擋泥性能，故而即便牌照托架8之後部82相對較小亦 不存在問題。即，可一方面維持擋泥性能，一方面使牌照 托架8之後部82緊湊化。 又，由於後擋泥板54發揮充分之擋泥性能，因此水或泥 等應該難以濺至配置於車輛之後側之零件即收納箱丨8及電 池盒11上。此外，由於牌照托架8之側部81覆蓋收納箱18 之#为及電池盒Η，因此可利用上述側部81將欲喷減至 參 收納箱18及電池盒11上之泥等抑制至某種程度。因此，可 將側蓋7之面積抑制得較小。即，能夠使侧蓋7緊湊化。 . 右僅增大後擋泥板54，則只會導致速克達型車輛i之後 ， 部大型化。然而，根據本實施形態，雖然後擋泥板54本身 增大，但牌照托架8之後部82及侧蓋7得到小型化，因此综 合來看，能夠實現速克達型車輛丨之後部之緊湊化。如 此，雖然先前一直認為若增大後擋泥板54將無法避免車輛 136684.doc -20- 201020154 後部之大型化，但本申請案發明者經努力研究結果得知， 若增大後撞泥板54來提高擋泥性能，則可按照擋泥性能提 南之情況’使其他部分以超過後擋泥板5 4之大型化之程度 而小型化。根據本實施形態’综合來看，能夠實現速克達 型車輛1之後部之緊湊化。藉由使與後輪53一同擺動之後 擋泥板54具有擋泥功能’即便於使其具有與以固定於車體 上之牌照托架8來擋泥之情形時相同程度之擋泥功能時， 亦可抑制後檔泥板5 4之大型化。因此’综合來看，能夠實 現速克達型車輛之後部之緊湊化。 又，根據本實施形態，如圖12所示，牌照托架8之車輛 上下方向之長度hi短於車輛前後方向之長度h2。又，牌照 托架8之車輛上下方向之長度!^短於車輛寬度方向之長度 h3(參照圖5)。即，將牌照托架8之車輛上下方向長度“設 定為相對較短。因此，能夠促進速克達型車輛1之後部之 緊湊化。 又’如圖12所示，牌照托架8以如下方式而形成，即， 當安裝有牌照80時，牌照托架8之後部82之下端82a位於較

The rear screed 54 extends in a front-rear direction from a position further forward than the center 53c of the rear wheel 53 toward a rear side of the rear end 53. Specifically, the rear mud plate 54 extends rearward from a position near the rear of the crankcase (not shown) of the engine unit 5, and extends rearward from the position T of the rear end of the rear wheel 53. The rear fender 54 is formed in a shape conforming to the shape of the rear wheel 53. That is, the rear fender 54 is formed in a substantially arc shape from the side. As shown in FIG. 4, the rear fender 54 includes a fender body 54& which covers one of the upper and left and right directions of the rear wheel 53, and a side panel portion 54b which is self-supporting the mud body 54a toward the left side and The right side protrudes; and the lower piece portion 54c protrudes obliquely downward from the lower side of the fender body 54a. As shown in Fig. 1, the lower end of the rear portion of the rear fender 54, i.e., the lower end 54d of the lower piece portion 54C, is located below the lower end 82a of the rear portion 82 of the license plate bracket 8. Further, the term "rear portion of the rear fender 54" means a portion which is rearward from the intermediate position in the front-rear direction of the rear fender 54. The side panel portion 541) and the lower panel portion 54c are also located below the lower end 82a of the license plate bracket 8. The upper end of the rear fender 54 is located at a height substantially equal to the upper end of the license plate bracket 8. <Effect of the Embodiment> As described above, the scooter type vehicle 1 of the present embodiment includes the license plate bracket 8 and the rear fender 54 as shown in Fig. 1 'package 136684.doc.19-201020154. The license plate bracket 8 includes side portions 81 on the left and right sides, and side portions 81 on the left and right sides of the rear portion 82 of the support plate 80. Each side portion 81 is disposed along a portion of the lower edge 73 of the side cover 7. Further, each of the side portions 81 covers a portion of the storage box 18 that is exposed downward from the lower edge 73 of the side cover 7 and the battery case 11 from the side. The rear fender 54 extends to a position further rearward than the position T of the rear end of the rear wheel 53. Further, the rear lower end 54d of the rear fender 54 is located below the lower end 82a of the rear portion 82 of the license plate bracket 8. According to this embodiment, since the rear fender 54 is sufficiently extended to the rear, the rear wheel 53 can be sufficiently covered. Thus, the rear fender 54 will exert sufficient mud retaining performance, so that there is no problem even if the rear portion 82 of the license plate bracket 8 is relatively small. That is, the mud retaining performance can be maintained on the one hand, and the rear portion 82 of the license plate bracket 8 can be made compact on the one hand. Further, since the rear fender 54 exhibits sufficient mud retaining performance, it is difficult for water or mud to splash onto the storage box 8 and the battery case 11 which are disposed on the rear side of the vehicle. In addition, since the side portion 81 of the license plate bracket 8 covers the container box 18 and the battery case, the side portion 81 can be used to suppress the mud to be sprayed onto the storage box 18 and the battery case 11 to a certain degree. Degree. Therefore, the area of the side cover 7 can be suppressed to be small. That is, the side cover 7 can be made compact. Increasing the rear fender 54 only on the right will only lead to the enlargement of the speed after the speed of the vehicle. However, according to the present embodiment, although the rear fender 54 itself is enlarged, the rear portion 82 and the side cover 7 of the license plate bracket 8 are miniaturized, so that the compactness of the rear portion of the scooter type vehicle can be achieved in a comprehensive manner. Chemical. In this way, although it has been previously thought that if the rear fender 54 is enlarged, the enlargement of the rear portion of the vehicle 136684.doc -20-201020154 cannot be avoided, but the inventors of the present application have made an effort to study the results, and if the increase is followed by the mud board In order to improve the mud-removing performance, it is possible to miniaturize the other parts in such a way that the size of the rear fenders 54 is larger than the size of the rear fenders. According to the present embodiment, the rear portion of the scooter type vehicle 1 can be made compact. The fender 54 has a mud retaining function by swinging together with the rear wheel 53. Even if it has the same degree of mudguard function as the case of retaining the mud by the license plate bracket 8 fixed to the vehicle body, It is also possible to suppress the enlargement of the rear fender 5 4 . Therefore, in a comprehensive manner, the compactness of the rear part of the Scooter type vehicle can be achieved. Further, according to the present embodiment, as shown in Fig. 12, the length hi of the license plate bracket 8 in the vertical direction of the vehicle is shorter than the length h2 of the vehicle longitudinal direction. Further, the length of the license bracket 8 in the vertical direction of the vehicle is shorter than the length h3 in the vehicle width direction (see Fig. 5). That is, the length of the license plate bracket 8 in the vehicle up-and-down direction is set to be relatively short. Therefore, the rear portion of the scooter type vehicle 1 can be made compact. Further, as shown in Fig. 12, the license plate bracket 8 is as follows. And formed, that is, when the license plate 80 is mounted, the lower end 82a of the rear portion 82 of the license plate bracket 8 is located above the lower end 8A of the license plate 80. Thus, the length of the vehicle in the up and down direction of the license plate bracket 8 is shorter. Therefore, it is possible to promote the compactness of the rear portion of the Scooter type vehicle 1. As shown in Fig. 12, the rear end 82a of the license plate bracket 8 is located further forward than the rear end i〇a of the tail light 10. That is, the license plate bracket 8 is placed. The protruding portion toward the rear is suppressed to be small. Therefore, the rear portion of the scooter type vehicle 1 can be made more compact. 136684.doc -21 · 201020154 Further, according to the present embodiment, as shown in FIG. The lower end 54d of the fender 54 is located below the center 53c of the rear wheel 53. That is, the rear support plate 54 is extended to the lower side. Therefore, the mud retaining performance by the rear fender W can be sufficiently improved. This can promote the compactness of the license plate bracket 8, etc. The rear fender 54 The fender body 54a includes a fender body 54a covering one of the upper and left and right directions of the rear wheel 53, and the side piece portion 54b' is located below the lower end 82a of the license plate bracket 8, The left side and the right side of the self-supporting mud board body 54a protrude. Therefore, the mud retaining performance of the mud board 54 can be further improved. Further, the rear fender 54 includes a lower piece portion 54c which is more than the lower end 82a of the license plate bracket 8. The lower position 'is protruded obliquely downward from the lower side of the fender body 54a. Thereby, the mud retaining performance of the fender 54 can be further improved. According to the present embodiment, as seen from the side, The support portion 9a of the upper rear buffer bracket 丨2 of the rear cushion unit 9 is located above the rear fender 54 and below the side 81 of the license plate bracket 8.
