Description

具有雙發泡吸振結構的記憶座墊
本創作係關於一種座墊的吸振結構，特別是一種具有雙發泡吸振結構的記憶座墊。
傳統的自行車或電動車座墊結構設計中，為了要使使用者在騎自行車或電動車時不致承受太大的振動，故大部份在座墊底部設置一對螺旋圈狀彈簧作為主要的吸振元件。但此類吸振結構在組件組裝時並不方便，需依賴大量人工，且在實際使用時，螺旋圈狀彈簧只能吸收較大的振動力。
而在座墊本體方面，有業者以各種不同的發泡材料、膠質材料、布料來製作座墊，以提供騎自行車或電動車時的舒適性。雖然簡化了組件的組裝問題，但實際使用時，其吸振效果並不理想。
緣此，本創作之主要目的即是提供一種具有雙發泡吸振結構的記憶座墊，以期提供自行車或電動車座墊在使用時的較佳吸振效果。
本創作所採用之技術手段係在座墊中包括有一第一發泡材料層以及形成在該第一發泡材料層上的高彈性發泡材料層。第一發泡材料層對應於該座墊的坐骨承壓區的位置處，形成一第一鏤空區，且在該第一鏤空區中結合一第二發泡材料層。高彈性發泡材料層對應於該坐骨位置處形成一第二鏤空區，且在該第二鏤空區中結合一記憶泡棉層，且該記憶泡棉層在一垂直方向對應於該第一鏤空區中的該第二發泡材料層。
其中，該座墊的該高彈性發泡材料層的表面還外覆一防水表層。
其中，該高彈性發泡材料層是選自聚氨酯材料、乙烯醋酸乙烯酯共聚物材料之一的發泡材料所製成。
其中，該第一發泡材料層是以聚丙烯材料所製成。
其中，該第二發泡材料層是以熱塑性橡膠材料所製成。
在效果方面，當騎乘者坐在座墊上，且座墊的坐骨承壓區承受該騎乘者的坐骨所施加的垂直方向的振動力時，可由本創作雙發泡吸振結構中的記憶泡棉層和第二發泡材料層共同吸收該振動力，可有效增加騎乘者的騎乘舒適性。
本創作所採用的具體技術，將藉由以下之實施例及附呈圖式作進一步之說明。

圖1顯示本創作在座墊結合雙發泡吸振結構的側視示意圖。
圖2顯示本創作在座墊結合雙發泡吸振結構的立體示意圖。
圖3顯示圖2中A-A斷面的剖視圖。
圖4顯示一騎乘者乘坐在如圖3的座墊時的剖視示意圖。
圖5顯示一騎乘者乘坐在座墊上，且騎乘者的坐骨施加振動力至座墊時的剖視示意圖。
請同時參閱圖1-2所示，其顯示本創作在座墊結合雙發泡吸振結構的側視示意圖，而圖2顯示本創作在座墊結合雙發泡吸振結構的立體示意圖。如圖所示，一座墊1的底部結合有一承架2，而承架2再結合一立柱3。座墊1可為一自行車或電動車的座墊。
當一騎乘者坐在該座墊1上時，該座墊1對應於該騎乘者的兩個坐骨位置處的局部區域係定義為坐骨承壓區P。本創作的設計中，係在該座墊1的 坐骨承壓區P設置一雙發泡吸振結構4。通過該雙發泡吸振結構4可使騎乘者得到舒適的騎乘效果。
圖3顯示圖2中A-A斷面的剖視圖。如圖所示，座墊1中包括有一第一發泡材料層5以及形成在該第一發泡材料層5上的高彈性發泡材料層6。高彈性發泡材料層6的表面還可以外覆一防水表層7。
第一發泡材料層5對應於該座墊1的該坐骨承壓區P的位置處，形成一第一鏤空區51，且在該第一鏤空區51中結合一第二發泡材料層41。第二發泡材料層41的材料密度較第一發泡材料層5的材料密度為小，使得第二發泡材料層41具有較佳的振動吸收能力。
在實際製作時，該第一發泡材料層5係可選用PP(Polypropylene，聚丙烯)的材料，且以發泡材料射出成型的工序完成具有第一鏤空區51的結構，再於第一鏤空區51中以第二次發泡材料射出成型的工序填入第二發泡材料層41。第二發泡材料層41可選用TPR(Themoplastic Rubber，熱塑性橡膠)的材料。
高彈性發泡材料層6對應於該坐骨位置P處形成一第二鏤空區61，且在該第二鏤空區61中結合一記憶泡棉層42，且該記憶泡棉層42在垂直方向對應於該第一發泡材料層5的第一鏤空區51中的第二發泡材料層41。記憶泡棉層42和第二發泡材料層41共同構成了本創作的雙發泡吸振結構4。
在實際製作時，高彈性發泡材料層6係可選用PU(Polyurethanes，聚氨酯)或EVA材料(Ethylene Vinyl Acetate，乙烯醋酸乙烯酯共聚物)的發泡材料，且以發泡材料射出成型的工序完成具有第二鏤空區61的結構，再於第二鏤空區61中以第二次發泡材料射出成型的工序填入記憶泡棉層42(Memory Foam)。該記憶泡棉層42是主要以聚氨酯高分子聚合物材料所製成，其具有兼具黏滯性(Viscosity)和彈性(Elasticity)的特性，當外力使該記憶泡棉層42變形後，該記憶泡棉層42會緩慢地回復原先形狀，以吸收衝擊動能。
圖4顯示一騎乘者8乘坐在如圖3的座墊1時的剖視示意圖，其顯示騎乘者8的坐骨81恰對應於座墊1的該坐骨承壓區P，且對應於記憶泡棉層42和第二發泡材料層41。
同時參閱圖5所示，當該座墊1的該坐骨承壓區P承受該騎乘者8的該坐骨31所施加的垂直方向振動力M時，可由記憶泡棉層42和第二發泡材料層41共同吸收該振動力，進而提昇騎乘的舒適性。
以上所舉實施例僅係用以說明本創作，並非用以限制本創作之範圍，凡其他未脫離本創作所揭示之精神下而完成的等效修飾或置換，均應包含於後述申請專利範圍內。
