Abstract

An electric bike lower pipe adopts a lower pipe body combined by a groove pipe and a buckling pipe, wherein the longitudinal whole shape of the lower pipe body is straight or arc or of the other special shapes, the whole section shape of the lower pipe body is mainly straight or arc, and the section outer periphery of the lower pipe body is closed, symmetrical, coordinated, smooth and uniform. The section of the groove pipe is mainly shaped like U, the groove pipe is solid or hollow, and when the groove pipe is hollow, the inner wall and the outer wall are connected with or without rib plates for supporting. The thickness of the groove pipe gradually decreases from the upper side and the lower side to the middle, so that the groove pipe is light in weight and high in strength. The section of the buckling pipe is shaped like U or of the other special shapes, the groove pipe can safely bear a load, the buckling pipe is easy to manufacture, can be manufactured into various models and meets use requirements, and a sealed space is formed between the groove pipe and the buckling pipe and used for containing a battery, a controller, an inserting part, a wire, a brake cable and the like. When the combined lower pipe is used for manufacturing an electric bike, the electric bike is low in manufacturing cost, simple in structure, light in weight, long in service life, balanced in weight, comfortable to ride, convenient to use, and novel, unique, coordinated, lively, smooth, beautiful and elegant in appearance.

Description

Manage under the Electrical Bicycle

Technical field

The present invention relates to manage under a kind of Electrical Bicycle.

Background technology

One of Electrical Bicycle main parts size is vehicle frame, and one of vehicle frame main parts size is lower pipe.At present, the vertical dominant shape of known lower pipe is take straight tube or bend pipe as main, and lower tube section is take pipe or oblate pipe as main, and existing all be wholely to manage down.At present, the most of battery case of known Electrical Bicycle is at the seat tube rear portion, and a part of battery-driven car electric wire, brake cable cloth are wanted the ledger line locations in lower tube outside on the lower pipe; Also some battery-driven car electric wire, brake cable cloth is in lower pipe pipe, at this moment, will drive in the front and rear part of lower pipe, wire hole, and tapping will be used the stiffener reinforcement.Therefore, more existing Electrical Bicycle outward appearances are not attractive in appearance, manufacturing cost is high, the center of gravity of car is higher, rear wheel load is bigger than normal, use is inconvenient.

Summary of the invention

In order to overcome the deficiency of existing Electrical Bicycle, the invention provides under the automobile-used compound type of a kind of electrical salf-walking and manage.

The technical scheme that its technical matters of invention solution adopts is:

Pipe is made of barrel and button pipe under the compound type, and the button pipe thread is combined in the barrel top.

The vertical overall appearance shape of pipe is take straight shape, arc as main under the compound type.

Pipe global sections profile be circular, oblate or other is special-shaped under the compound type, under the compound type tube section periphery closed, symmetrical, coordinate, smooth, even.

The barrel cross section, take U-shaped as main, barrel is real core or hollow with metallic material or composite material manufacturing, barrel, when hollow, have between inwall and the outer wall or supports without link of boards.

Barrel thickness is reduced to the centre gradually by the limit, up and down, reduces weight to reach, puies forward high-intensity purpose.

The button tube section is U-shaped or other abnormity, and button pipe plastic or other material are made.

The space that a sealing is arranged between barrel and the button pipe.

The invention has the beneficial effects as follows that closed, symmetrical, the coordination, smooth, even of tube section periphery can have abundant moulding under the compound type; Barrel can bearing load, guarantees that vehicle frame is safe and reliable; The button pipe manufacturer is simple and easy, can satisfy various moulding and user demand.

Adopt the Electrical Bicycle of pipe manufacturer under the compound type, can easily the parts such as battery, controller, plug-in unit, electric wire, brake cable be placed in the lower pipe; Low cost of manufacture, simple for structure, lightweight, life-span length, balanced weight, ride comfortable, easy to use; Profile novelty, uniqueness, coordination, lucid and lively, smooth, attractive in appearance, generous; Has distinct novelty, significant practicality, outstanding creativeness.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 manages front view under the compound type.

Fig. 2 is the cross section view along A-A line among Fig. 1.

Fig. 3 is the Electrical Bicycle front view with pipe manufacturer under the compound type.

1 barrel, 2 button pipes among the figure.

The specific embodiment:

Fig. 1, Fig. 2 show: button pipe 2 is fastened on the top of barrel 1, barrel 1 forms under the compound type with button pipe 2 manages, and the vertical overall appearance shape of pipe is arc under the compound type, pipe global sections profile be oblate and other under the compound type, and cross-sectional shape is closed, symmetrical, coordinate, smooth, even.

Fig. 2 shows: the space of a sealing is arranged, the parts such as the space of this sealing can placing battery, controller, plug-in unit, electric wire, brake cable between barrel 1 and the button pipe 2.Barrel 1 is hollow, can have link of boards to support between barrel 1 inwall and the outer wall, and barrel 1 wall thickness is reduced to the centre gradually by the limit, up and down, has reached reduction weight, has put forward high-intensity purpose.

Fig. 3 shows: the Electrical Bicycle that adopts pipe manufacturer under the compound type, can easily the parts such as battery, controller, plug-in unit, electric wire, brake cable be placed under the compound type in the pipe, easily manufactured, simple for structure, lightweight, life-span length, balanced weight, ride comfortable, easy to use, profile novelty, uniqueness, coordination, lucid and lively, smooth, attractive in appearance, generous have distinct novelty, significant practicality, outstanding creativeness.

Claims

1. manage under an Electrical Bicycle, comprise barrel, it is characterized in that: adopt barrel to manage under the compound type with button and manage, the button pipe thread is combined in the barrel top; The vertical monnolithic case of pipe is take straight shape, arc as main under the compound type, pipe global sections profile is circular, oblate under the compound type, closed, symmetrical, the coordination, smooth, even of tube section periphery under the compound type, the barrel cross section is take U-shaped as main, barrel is real core or hollow with metallic material or composite material manufacturing, barrel, when hollow, have between inwall and the outer wall or support without link of boards, barrel thickness is reduced to the centre gradually by the limit, up and down; The button tube section is U-shaped, the manufacturing of button pipe plastic; The space of a sealing is arranged between barrel and the button pipe, and the space of this sealing is placing battery, controller, plug-in unit, electric wire, brake cable easily; Barrel is bearing load reliably.
