Abstract

The utility model discloses a front tripod assembly of a foldable electric vehicle. The front tripod assembly comprises a headstock rack, an upper cross beam and a lower cross beam, wherein both the upper cross beam and the lower cross beam are hinged on the headstock rack; the front tripod assembly further comprises a brace rod; one end of the brace rod is hinged with the upper cross beam, and the other end thereof is connected with the lower cross beam in a sliding manner; a sliding groove is formed on the lower cross beam; swing grooves are formed on both sides of the sliding groove; a sliding piece is arranged at the end part of the brace rod; and flanges arranged on two sides of the sliding piece are inserted in the swing grooves of the sliding groove and are in slide fit with the swing grooves. The utility model ensures that the foldable electric vehicle can be folded more smoothly, and can prolong the service life of the foldable electric vehicle.

Description

The preceding spider assembly of electric motor bicycle with folding

Technical field

The utility model relates to a kind of preceding spider assembly of electric motor bicycle with folding.

Background technology

The preceding tripod assembly of traditional electric motor bicycle with folding is to be hinged with the slippage pipe on the entablatrance, be hinged with down the slippage pipe on the cross sill, last slippage pipe is that suit is connected with following slippage pipe, in folding process, last slippage pipe telescopic slide up and down in following slippage pipe, though such structure is feasible, but, after repeatedly folding, can produce and go up slippage pipe phenomenon under the slippage pipe friction, the inner wall abrasion of following slippage pipe is serious, influences the folding of battery-driven car, perhaps even following slippage tube stay break, influenced the service life of electric motor bicycle with folding.

Summary of the invention

The purpose of this utility model is to provide a kind of electric motor bicycle with folding that makes folding smooth and easy, and can improve the preceding spider assembly of electric motor bicycle with folding in the service life of electric motor bicycle with folding.

In order to achieve the above object, the technical solution of the utility model is: a kind of preceding spider assembly of electric motor bicycle with folding, comprise headstock frame, entablatrance and cross sill, entablatrance and cross sill all are hinged on the headstock frame, also has strut, one end and the entablatrance of strut are hinged, and the other end is connected with the cross sill slippage.

Have slippage slot on the described cross sill, the both sides of slippage slot all have wing groove, and the end of strut has sliding component, and the both sides of sliding component have flange, flange be inserted in the wing groove of slippage slot and with wing groove bearing fit.

The lower end of described headstock frame is provided with front fork, and entablatrance and cross sill all are hinged on the front fork.

Described entablatrance is provided with the strut hinged-support, and strut is hinged by strut hinged-support and entablatrance.

After adopting said structure, owing to have strut, one end and the entablatrance of strut are hinged, the other end is connected with the cross sill slippage, therefore the good and cross sill slippage of strut energy in the battery-driven car folding process, this slippage cooperate can make folding more smooth and easy, and the wearing and tearing of cross sill are dropped to minimum, the service life of having improved battery-driven car.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Shown in Fig. 1,2,3,4, a kind of preceding spider assembly of electric motor bicycle with folding comprises headstock frame 1, entablatrance 2 and cross sill 3, entablatrance 2 and cross sill 3 all are hinged on the headstock frame 1, also have strut 4, an end and the entablatrance 2 of strut 4 are hinged, and the other end is connected with cross sill 3 slippages.

Shown in Fig. 2,3,4, for strut 4 is slided on cross sill 3 smoothly, has slippage slot 3-1 on the described cross sill 3, the both sides of slippage slot 3-1 all have wing groove 3-1-1, the end of strut 4 has sliding component 5, the both sides of sliding component 5 have flange 5-1, flange 5-1 be inserted in the wing groove 3-1-1 of slippage slot 3-1 and with wing groove 3-1-1 bearing fit.

Referring to shown in Figure 1, be hinged on the headstock frame 1 in order to make entablatrance 2 and cross sill 3, the lower end of described headstock frame 1 is provided with front fork 1-1, and entablatrance 2 and cross sill 3 all are hinged on the front fork 1-1.

Referring to shown in Figure 1, be hinged on the entablatrance 2 in order to make strut 4, described entablatrance 2 is provided with strut hinged-support 2-1, and strut 4 is hinged by strut hinged-support 2-1 and entablatrance 2.

Shown in Fig. 2,5,6, when the utility model uses, referring to Fig. 5, one end of entablatrance 2 and cross sill 3 is hinged on the front fork 1-1 of headstock frame 1, the other end of entablatrance 2 and cross sill 3 is hinged on the Vee formation frame assembly, one end of strut 4 is hinged on the strut hinged-support 2-1 of entablatrance 2, and the other end cooperates with cross sill 3 slippages; In folding process, referring to Fig. 6, the sliding component 5 of strut 4 slowly slides in the slippage slot 3-1 of cross sill 3; Slippage cooperate can make folding more smooth and easy, and the wearing and tearing of cross sill 3 are dropped to minimum, the service life of having improved battery-driven car.
