Abstract

The utility model relates to the technical field of electric bicycles, in particular to an electric bicycle frame. The electric bicycle frame comprises a head pipe fitting, a first upper pipe fitting, a second upper pipe fitting, a lower pipe fitting and a seat pipe fitting. The head pipe fitting is fixedly connected with the upper end of the lower pipe fitting. The lower pipe fitting and the seat pipe fitting are fixedly connected through the first upper pipe fitting and the second upper pipe fitting. The inside of lower pipe fitting is hollow. A containing chamber is formed by the hollow part of the lower pipe fitting, and is used for containing a rechargeable battery component. A plurality of through holes are formed in the lower pipe fitting and are communicated with the containing chamber. Due to the fact that a built-in mode of arranging the rechargeable battery component of an electric bicycle in the containing chamber is adopted, the appearance of the whole electric bicycle is artistic, gravity center of the whole electric bicycle is lowered, and safety and reliability are improved when the electric bicycle is in motion. In addition, due to the facts that a gap between the rechargeable battery which is arranged in the lower pipe fitting in a built-in mode and the ground is small, when the rechargeable battery is taken out, the electric bicycle need turning over, and difficulty of stealing the rechargeable battery is improved.

Description

A kind of electric bicycle fame

Technical field

The utility model relates to the Electrical Bicycle technical field, particularly a kind of electric bicycle fame.

Background technology

At present, the use of Electrical Bicycle is very general, the power of Electrical Bicycle come in the rechargeable battery that carries with car, rechargeable battery all adopts external mode, the Electrical Bicycle that has is installed in rechargeable battery on the front tripod of car, on the Vee formation frame that is installed in car that has, on the rear clothes hanger that is installed on bicycle that also has.The external one side of rechargeable battery affects the car load outward appearance; and be unfavorable for the riding safety of vehicle; particularly rechargeable battery is installed on the rear clothes hanger; make and move on the center of gravity of car and play pendulum; therefore the safety and reliability during Vehicle Driving Cycle descends, and on the other hand, adopts the external mode of rechargeable battery to be dismantled pilferage by the lawless person easily because the price of rechargeable battery is higher; for preventing that stolen need from installing in addition anti-theft column lock rechargeable battery is carried out anti-theft protection, therefore increased cost.

The utility model content

The utility model in order to solve Electrical Bicycle since rechargeable battery external cause affect outward appearance and the high problem of cost, and a kind of electric bicycle fame that provides.

For reaching above-mentioned functions, the technical scheme that the utility model provides is:

A kind of electric bicycle fame, comprise on the first pipe fitting, first on the pipe fitting, second pipe fitting, lower pipe fitting and sit pipe fitting, described first pipe fitting is captiveed joint with the upper end of described lower pipe fitting, described lower pipe fitting is captiveed joint with pipe fitting on described second with described the seat between the pipe fitting by pipe fitting on described first, described lower pipe fitting is the pipe fitting of inner hollow, hollow space forms a container cavity, is used for holding rechargeable battery, and described lower pipe fitting is provided with the through hole that several and described container cavity connect.

Preferably, the bottom surface of described lower pipe fitting is provided with groove along the length direction of described lower pipe fitting.

Preferably, described electric bicycle fame also comprises an end cap, and the lower end of described end cap and described lower pipe fitting fastens.

Preferably, be provided with several butt strips to be spaced mode above the described groove.

The beneficial effects of the utility model are: a kind of electric bicycle fame, comprise on the first pipe fitting, first on the pipe fitting, second pipe fitting, lower pipe fitting and sit pipe fitting, described lower pipe fitting is the pipe fitting of inner hollow, hollow space forms a container cavity, owing to adopt the rechargeable battery assembly of Electrical Bicycle is arranged on the interior built-in mode of described container cavity, so the appearance looks elegant of car load; On the other hand, the rechargeable battery assembly is arranged in the described lower pipe fitting so that the whole decentralization of Electrical Bicycle, the reliable degree when having improved Vehicle Driving Cycle; Moreover, be built in the rechargeable battery in the described lower pipe fitting because overhead the gap is smaller, need in the time of therefore will taking out rechargeable battery to turn Electrical Bicycle, this has also improved the difficulty that the lawless person steals rechargeable battery.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the cross sectional representation of lower pipe fitting;

Fig. 3 is lower pipe fitting and the scheme drawing that cooperates of end cap.

The specific embodiment

Below in conjunction with accompanying drawing 1 to Fig. 3 the utility model is further elaborated:

A kind of electric bicycle fame as shown in Figure 1, comprise first pipe fitting 1, pipe fitting 2 on first, pipe fitting 3 on second, lower pipe fitting 4 and sit pipe fitting 5, first pipe fitting 1 is captiveed joint with the upper end of described lower pipe fitting 4, lower pipe fitting 4 is captiveed joint with described the seat between the pipe fitting 5 by pipe fitting 3 on the pipe fitting 2 and second on first, for the Joint strenght that reaches captive joint adopt in the present embodiment be the welding mode, lower pipe fitting 4 is pipe fittings of inner hollow, hollow space forms a container cavity 41, be used for holding rechargeable battery assembly (not shown), for reaching light effect, rechargeable battery of the present utility model preferentially adopts lithium electricity rechargeable battery.

As shown in Figure 1, the bottom surface of the lower pipe fitting 4 of the Electrical Bicycle after the assembling is provided with two through holes 42, in the cavity volume of lower pipe fitting 4 control path of rechargeable battery assembly and feed circuit is drawn being convenient to.

When the electric weight of rechargeable battery exhausts, charge to rechargeable battery for convenient, the side of lower pipe fitting 4 also is provided with the through hole 42 that connects with container cavity 41, the charging inlet of rechargeable battery is arranged on through hole 42 places, when electric quantity of rechargeable battery exhausts, just can be connected the interface of charge power supply with the charging inlet of rechargeable battery by this through hole 42 like this.

As depicted in figs. 1 and 2, the bottom surface of lower pipe fitting 4 is provided with groove 43 along the length direction of lower pipe fitting 4, the control path of above-mentioned rechargeable battery and feed circuit can be arranged in the groove 43, can stash above-mentioned control path and feed circuit well like this, make the integral body place of bicycle see more attractive in appearance.

As shown in Figure 1, be not easy to drop out in groove 43 for making above-mentioned control path and feed circuit, groove 43 tops are welded with several butt strips 7 and are used for stopping that circuit deviates to be spaced mode.

As shown in Figure 3, electric bicycle fame also comprises an end cap 6, and end cap 6 fastens with the lower end of lower pipe fitting 4, and to increase aesthetics, when preventing from simultaneously riding in the rainy day, the water droplet that the bicycle rear tire takes up is splashed into and causes the rechargeable battery assembly to damage in the cavity volume.

The above embodiment, it is preferred embodiments of the present utility model, be not to limit practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, all should be included in the utility model patent claim.
