Description

Wire passing plug and electric bicycle frame

Technical Field

The utility model relates to a wire passing plug for assembling a wire harness on an electric bicycle frame.

Background

In order to pursue the aesthetic design of the electric bicycle, the wire harness on the electric bicycle is generally subjected to hiding treatment. The wire harness comprises a signal wire, a brake cable and the like. The hidden mode is to put the wire harness into a cavity of a pipe structure of the frame, so that the wire harness is prevented from being exposed in a visible area outside the frame as much as possible. The wire harness at the handle position of the frame can be inserted into the head pipe position of the electric bicycle frame, and as the head pipe is a metal piece, the head pipe can form sharp burrs or edges at the through holes through the hole structure of the wire harness. For wire harnesses, once wear occurs, this means that there is a significant safety hazard.

In order to match with the hidden design of the wire harness in the prior art, a wire passing plug for protecting the wire harness is usually arranged at the through hole of the head pipe. The wire passing plug is made of plastic material and is fixed on the head pipe through screws. The wire passing plug is embedded in the through hole, and the wire harness only contacts with the wire passing plug when passing through the through hole. As shown in fig. 1 and 2, two portions of the wire passing plug for passing through the wire harness are respectively provided with a through hole, and the wire passing plug is sleeved on the wire harness once the wire harness passes through the through holes. If the wire passing plug is to be replaced, the wire harness must be pulled away from the wire passing plug, that is, the wire passing plug can be replaced only when the wire harness is pulled away. The wire passing plug replacement mode seriously damages the assembly state of the whole vehicle, and because a certain assembly process can be completed by using special tools of original factories and through adjustment and detection, the assembly quality of the whole vehicle is obviously reduced once the whole vehicle is assembled after being disassembled. Therefore, the replacement of the wire passing plug in the prior art is extremely unchanged and difficult.

Disclosure of Invention

The utility model aims to solve the technical problem of simplifying the replacement operation of the wire passing plug, thereby obtaining the wire passing plug suitable for the frame of the electric bicycle.

In order to solve the technical problems, the utility model adopts the following technical scheme: this cross line stopper is tubular structure, one side of crossing the line stopper is equipped with the assembly mouth, the assembly mouth extends to the other end of crossing the line stopper from the one end of crossing the line stopper, assembly mouth and the inside intercommunication of crossing the line stopper, it is equipped with the spacing groove to cross the line stopper outside, spacing groove and assembly mouth intercommunication, it is equipped with flaky spacing piece to cross the inside of line stopper, spacing piece is expanded in the direction of perpendicular assembly mouth extending direction, spacing piece links as an organic whole with crossing the line stopper, be equipped with the through wires hole on the spacing piece, the through wires hole includes central region and linking area, the width of linking area is less than the width of central region, central region is located the central position of spacing piece, the through wires hole extends to the assembly mouth from the central position of spacing piece, linking area is located between central region and the assembly mouth.

The design thought basis of the improved wire passing plug in the technical scheme is to change the assembly process of the wire passing plug; on the basis, the assembly process that the wire harness passes through the wire passing plug, namely the wire passing plug sleeve, to the outside of the wire harness is abandoned, and the assembly thought that the wire harness is embedded from the side of the wire passing plug is changed. Therefore, the wire passing plug is provided with the assembly opening while retaining the filling structure, the length of the assembly opening is consistent with that of the wire passing plug, and the wire harness is only required to be extruded into the wire passing plug from the assembly opening during assembly. The simplified assembly operation eliminates threading the wire harness from the end into the wire passing plug, which is positioned in any lateral area of the wire harness, and then the wire harness is threaded through the assembly opening into the wire passing plug. When the wire passing plug is detached, the wire passing plug is directly peeled off from the wire harness. The wire passing plug is convenient to combine with the wire harness.

The combination mode of the wire passing plug and the head pipe is that the head pipe is embedded in the limit groove of the wire passing plug. The wire passing plug is made of plastic material and has a structure with an assembling port, so that the whole wire passing plug has remarkable elastic deformation capability. The appearance of the wire passing plug can be changed after the wire passing plug is extruded.

The thickness of the limiting sheet inside the wire passing plug is smaller than that of other parts of the wire passing plug, so that the flexibility characteristic of the limiting sheet is more remarkable. The wire passing plug is used for preventing the wire harness from directly contacting with the head pipe at the through hole of the head pipe, and the limiting piece has the function of keeping proper sliding quantity between the wire harness and the wire passing plug, so that the wire harness is not blocked by the wire passing plug. Because the conditions that the frame is fluctuated and the vehicle turns forward are avoided in the using process of the vehicle, most parts of the wire harness are easy to shake adaptively under the conditions, the wire harness is kept to shake properly in the wire passing plug, and the riding state of the whole vehicle can be matched better. Otherwise, when the wire harness is tightly connected with the wire passing plug, relative movement cannot be generated between the wire harness and the wire passing plug, and fatigue damage is easily caused by excessive shaking of the wire harness at a local part. The wire passing plug has a structure to protect the wire harness.

For the wire passing plug, the elastic capability of the limiting piece can be fed back to the wire passing plug, so that the elastic deformation capability of the wire passing plug is enhanced.

The technical scheme provides the spacing piece structure of preferred, still be equipped with first trompil and second trompil on the spacing piece, first trompil and second trompil are straight structure, the one end of first trompil and the one end of second trompil all communicate with central region and all extend in the direction of keeping away from central region, the spacing piece separates through first trompil, second trompil, through wires hole and forms valve I, valve II, valve III all are located valve I's top, valve II's area is greater than valve III's area. The limiting piece tends to the split type structure, is favorable to promoting the deformability of limiting piece, and then obtains stronger pencil protection effect.

As described above, the wire passing plug is inserted into the inside of the head pipe by pressing, and the outer structure of the wire passing plug is optimized for the convenience of the assembly operation. The wire plug is characterized in that a bulge I and a bulge II are arranged outside the wire plug, the bulge I is located at the end part of the wire plug, the bulge I is distributed around the wire plug in a continuous mode, the length of the bulge I is larger than that of the bulge II, two ends of the bulge I are located at two sides of an assembly opening, two bulges II are respectively distributed at two sides of the assembly opening, two bulges II are separated, and a limiting groove is located between the bulge I and the bulge II.
