Abstract
The utility model discloses an electric vehicle rear fork which comprises two side tubes arranged in parallel, a main tube welded at one end of each side tube and an auxiliary tube, wherein the auxiliary tube is parallel to the main tube and is welded between the two side tubes, and mounting pieces are correspondingly arranged on the two side tubes; a damper fixed on two side tubes is arranged between the main tube and the auxiliary tube; damping rubber plugs are arranged at two ends of the main tube; and the mounting pieces are 1.5-3.5 mm thick. The electric vehicle rear fork is simple in structure and convenient to use; the damper fixed on two side tubes and the damping rubber plugs mounted at two ends of the main tube can enhance the damping effect of the rear fork; and the thicknesses of the mounting pieces on the side tubes are increased to 1.5-3.5 mm, so that the strength of the rear fork can be effectively enhanced.
Description
Technical field
The utility model relates to battery-driven car parts, be specifically related to a kind of can the not rear chain stay that is applicable to Electrical Bicycle or battery-operated motor cycle of easy fracture of damping.
Background technology
Rear bottom fork of electric vehicle is one of major part of battery-driven car.In the process of moving, especially Uneven road time vibrations are very large, can produce irreparable harm to vehicle for vehicle, therefore, are that Electrical Bicycle or battery-operated motor cycle all can mounting shock absorbers, to reach the object of effective damping.Rear chain stay is often arranged on the centre or wheel hub of vehicle frame, and rear chain stay does not but have bumper.And the rear chain stay of installing on these vehicles is mainly box-section tubular structure, when road conditions are poor, installation sheet and rear chain stay body frame easily rupture, and make troubles to people's trip.When after chain stay generally cannot keep in repair after there is crack conditions, therefore can only integral replacing after chain stay, economic cost is very high.As manufacturer, be necessary for that client provides better, the product of high-quality, therefore, be badly in need of damping, the shock resistance of chain stay after improving, improve the intensity of rear chain stay, design a kind of novel rear bottom fork structure.
The thickness of simultaneously considering the installation sheet on existing rear chain stay is only 0.5-1.2mm, under the vibrations of strong external force, also easily ruptures, and therefore, also needs its thickness to promote, to improve integral quakeproof, the cushioning ability of rear chain stay.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of rear bottom fork of electric vehicle, by set up the method for shock absorption device and increase installation sheet thickness, the problem that solves rear chain stay undercapacity of the prior art and easily rupture on rear chain stay.
For achieving the above object, the utility model adopts following technical scheme:
A kind of rear bottom fork of electric vehicle, comprises two side pipes that be arranged in parallel, is welded on the supervisor of two lateral canal one end, and and supervisor be welded on the looped pipeline between two lateral canals in parallel, on described two lateral canals, correspondence is provided with installation sheet; Between described supervisor and looped pipeline, be provided with the bumper being fixed on two lateral canals; Described supervisor's two ends are provided with yielding rubber plug; The thickness of described installation sheet is 1.5-3.5mm.
Preferably, the thickness of described installation sheet is 2.5mm.
By the enforcement of above technical scheme, the utlity model has following beneficial effect:
Simple in structure, easy to use; Be fixed on the bumper on two lateral canals, and be arranged on the yielding rubber plug at supervisor two ends, can strengthen the damping effect of rear chain stay; Installation sheet thickness on side pipe increases to 1.5-3.5mm, can effectively increase the intensity of rear chain stay.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing that embodiment is used is briefly described, apparently, accompanying drawing in the following describes is only an embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to this accompanying drawing other accompanying drawing.

Fig. 2 is the disclosed a kind of rear bottom fork of electric vehicle back view of the utility model embodiment 1;
Fig. 3 is the structural representation at A-A place in Fig. 1.
The represented corresponding component title of numeral in figure:
1. side pipe 2. is responsible for 3. looped pipeline 4. installation sheet 5. bumper 6. yielding rubber plugs
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of rear bottom fork of electric vehicle, comprise two side pipes that be arranged in parallel 1, be welded on the supervisor 2 of two lateral canal 1 one end, and and supervisor's 2 looped pipelines 3 that are welded in parallel between two lateral canals 1, on described two lateral canals 1, correspondence is provided with the installation sheet 4 that rear chain stay can be connected with other parts of battery-driven car; Between described supervisor 2 and looped pipeline 3, be provided with the bumper 5 being fixed on two lateral canals 1; Described supervisor's 2 two ends are provided with yielding rubber plug 6; The thickness of described installation sheet 7 is 1.5-3.5mm.The installation of bumper can effectively alleviate the vibrations of external force for rear chain stay, makes vehicle smooth-ride, reduces to jolt.
The thickness of installation sheet 4 described in the present embodiment is made as 2.5mm.
Connection mode between described bumper and two lateral canals is for being flexibly connected, good damping effect; Between above-mentioned other each parts, all adopt welding manner to connect.
Wherein, described supervisor two ends are provided with the negative thread matching with yielding rubber plug, and yielding rubber plug is provided with corresponding outside thread, and the two closely cooperates, and actv. alleviates vibrations, and after protection, chain stay can be not destroyed.
By the enforcement of above technical scheme, the utlity model has following beneficial effect:
Simple in structure, easy to use; Be fixed on the bumper on two lateral canals, and be arranged on the yielding rubber plug at supervisor two ends, can strengthen the damping effect of rear chain stay; Installation sheet thickness on side pipe increases to 1.5-3.5mm, can effectively increase the intensity of rear chain stay.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
