當本創作使用遇到路面上、下起伏時，承載兩後輪以 及後輪軸座的偏轉架會隨著活動架以底盤構造後端兩側的 框轴為圓心上、下擺動，此時可利用主避震器的緩衝構造 進行上 '下擺動行程的緩衝，減緩地形的起伏造成電動代 步車底盤構造上'下的震動。 本創作的有益效果在於，當電動代步車路經轉彎的路 段或者單側的地面起伏過大時，此時由於偏轉架藉由套管 以可左、右擺動的方式套設結合在活動架的直管後半段， 加上活動架與偏轉架的兩側之間對稱設有兩輔助避震器， 因此這時除了主避震器能發揮上、下避震的作用以外，兩 輔助避震器還可提供兩後輪侧向左、右擺動起伏的緩衝效 果，如此能進一步穩定底盤構造的重心，增加車輛行駛的 穩定性與安全性。 【實施方式】 本創作提供一種電動代步車之後避震裝置，如圖彳至 圖5所示的較佳實施例，包括： 一底盤構造1〇,設有一底盤U，在底盤W後端的左、 5 M407879 右兩側以沿左、右方向延伸的形“ 12,又在底盤U後側的中間朝 抱轴 , 又—座桿1 3，在座裎 13後面的頂部結合一朝後延伸的主 隹1杯 义辰态頂座1 4。 一活動架2Q，配合底盤構造1Q的兩_12分別 一套管21,藉由各套管21以可 有 1 2，在各奎总；μ妊八4 、厂L、套設在各樞軸 在各套s 21…朝後延伸的側桿22，在各側桿㈡ 的内側面以沿左、右方向延伸的形態結合一朝内橫向延伸 的前橫桿23,兩前橫桿23為左、右對稱的形態，在兩前橫 桿23的内端之間結合一沿前、後方向延伸的直管μ，其： 圓形的管體並且以前半段的左、右兩側面結合兩前橫桿Μ 的内端，於直f 24的内部形成—沿前後方向延伸的直孔 24i ’又在直管24外周面的後半段形成一外徑較小的套a 部242,在套合部242周圍套設—襯套243,在襯套2钓 的外周面以環繞的形態凹設一滑動槽244; 在各側桿22内側的頂部結合—上凸且朝後延伸的支架 25在各支架25的頂部以沿左、右方向延伸的形態朝外橫 向伸設一輔助避震頂座26,兩輔助避震頂座26為左、右= 稱的形態，在兩支架25之間結合-主避震器底座27,其位 於主避震器頂座14正下方的後面，在主避震器底座27與When the creation encounters the ups and downs of the road surface, the deflection frame carrying the two rear wheels and the rear wheel axle seat will swing upward and downward with the frame axis of the movable frame at the rear end of the chassis structure as the center of the frame. The cushioning structure of the main shock absorber is buffered by the upper 'down swing stroke, which slows down the fluctuation of the terrain and causes the vibration of the electric scooter chassis structure. The beneficial effect of the creation is that when the electric scooter passes through the turning section or the ground undulation of one side is too large, at this time, since the deflection frame is sleeved in the left and right swinging manner, the straight frame is combined with the movable frame. In the latter half of the pipe, two auxiliary shock absorbers are symmetrically arranged between the movable frame and the two sides of the deflection frame. Therefore, in addition to the main shock absorber, the auxiliary shock absorber can also be used for the upper and lower suspension. The buffering effect of swinging the left and right sides of the two rear wheels is provided, which can further stabilize the center of gravity of the chassis structure and increase the stability and safety of the vehicle.
