The invention provides a rear suspension structure of an electric vehicle, which comprises a front lower pull rod, a front upper pull rod, a rear upper pull rod and a spring arm which are arranged between an auxiliary frame and wheels, and further comprises a spring arranged on the spring arm, the front lower pull rod and the front upper pull rod are arranged in a forward inclined mode, and the rear upper pull rod is arranged in a backward inclined mode; the front upper pull rod is located above the front lower pull rod, and the front upper pull rod and the front lower pull rod are arranged in a staggered mode. And the spring arm is positioned between the front upper pull rod and the rear upper pull rod. The front lower pull rod and the front upper pull rod are obliquely arranged forwards, the rear upper pull rod is obliquely arranged backwards, the front upper pull rod is located above the front lower pull rod, and the front upper pull rod and the front lower pull rod are arranged in a staggered mode, so that X-direction force can be transmitted through the front upper pull rod, the front lower pull rod and the rear upper pull rod, a longitudinal arm in the prior art is omitted, and space is saved; therefore, the arrangement space and the capacity of the battery are effectively increased, and the investment of the battery module is reduced.
本发明提供了一种电动车后悬架结构,其包括设置在副车架与车轮之间的前下拉杆、前上拉杆、后上拉杆、弹簧臂,其还包括设置在弹簧臂上的弹簧,所述前下拉杆和所述前上拉杆分别向前倾斜设置,所述后上拉杆向后倾斜设置;所述前上拉杆位于所述前下拉杆的上方,所述前上拉杆与所述前下拉杆交错设置;所述弹簧臂位于所述前上拉杆与所述后上拉杆之间。本发明的前下拉杆和前上拉杆分别向前倾斜设置,后上拉杆向后倾斜设置,前上拉杆位于前下拉杆的上方,前上拉杆与前下拉杆交错设置,从而利用前上拉杆、前下拉杆以及后上拉杆能够传递X向的力,省去了现有技术中的纵臂,节省了空间,从而有效地增大了电池的布置空间和电池容量,减少电池模组的投入。
