Description

电动代步车车架结构 技术领域
本发明涉及一种代步车结构，具体地说，涉及一种冲压式的电动代步车车架结构。
背景技术
目前的电动代步车的车架一般是由很多的小零件通过焊接成一整体，缺点是：物料多，制造成本、管理成本、人力成本高。
中国专利CN 203497091公开了一种组合式电动代步车车架结构，其特征在于，包括：一前车架，所述前车架设有至少一横杆与多个前侧杆，该多个前侧杆并排间隔设置，该多个前侧杆一端设有一凹形枢接座，且该多个前侧杆侧边设有多个通孔，所述横杆两端分别设有一凸柱，通过所述横杆的凸柱与该多个前侧杆侧边的通孔相互嵌合锁固，并于嵌合处设有至少一锁合元件锁固；但是该专利结构复杂，生产成本高。
发明内容
为了解决上述现有技术的不足之处，本发明的目的在于提供一种结构简单、生产方便的电动代步车车架结构，以克服现有技术中的缺 陷。
为了实现上述目的，本发明提供了一种电动代步车车架结构，所述电动代步车车架结构包括前车架和后车架，所述前车架和后车架均为一体成型的冲压钣金，所述前车架与后车架通过转轴可上下转动地轴连接，前车架与后车架之间的转轴外套设有缓冲弹簧，缓冲弹簧外套设有丁基橡胶制成的圆筒，圆筒的长度等于缓冲弹簧长度的40％。
作为对本发明所述的电动代步车车架结构的进一步说明，优选地，所述前车架和后车架整合成一件一体成型的钣金件。
作为对本发明所述的电动代步车车架结构的进一步说明，优选地，所述前车架和后车架均为腔形冲压件。
由此可见，本发明提供一种电动代步车车架结构，所述电动代步车车架结构包括前车架和后车架，所述前车架和后车架均为一体成型的冲压钣金，所述前车架与后车架通过转轴可上下转动地轴连接，前车架与后车架之间的转轴外套设有缓冲弹簧，缓冲弹簧外套设有丁基橡胶制成的圆筒，圆筒的长度等于缓冲弹簧长度的40％。由于本发明将许多零件整合成一个或两个腔型结构的冲压件，零件制作容易实现即机械化及自动化，可以大大的减少车架零件的制作成本，减少焊接点数从而减少焊接成本，由于焊点的减少，使得整体车架由于焊接而引起的焊接变形就减小，从而提高了良品率，从而降低整体车架的制作成本，由于将零散的零件整合，所以外观上比原来的要美观。
