Description

A type of wire protection plug for converting folding bicycles into electric vehicles Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically to a wire protection plug for converting folding bicycles into electric vehicles. Background Technology

[0002] Bicycles, as a traditional means of transportation, have always been popular. However, bicycles are only suitable for low-speed, short-distance travel and cannot travel long distances at high speeds like traditional electric bicycles. Furthermore, traditional electric bicycles are bulky and cannot be easily accessed or parked in public places (shopping malls, pedestrian streets, subways, etc.). Therefore, more and more people are choosing to modify their folding bicycles into e-bikes.

[0003] Currently, the issue of power cable routing arises when converting folding bicycles to electric-assist bikes. Typically, the power cable is exposed during conversion, offering poor protection and making it prone to damage. Furthermore, the exposed cable is visually unappealing and unacceptable to users (high-end bicycle enthusiasts generally consider exposed power cables unsightly; a fully exposed cable equates to a cheap look. They don't want their expensive bicycles to appear cheap simply because of the electric-assist conversion). To address this, some people choose to run part of the power cable through the seatpost to conceal most of the wiring. However, this method still has drawbacks: the lack of a restraint mechanism at the bottom of the seatpost allows the cable to wobble, which is unsightly. Additionally, when the seatpost is lowered during folding, the lower end of the cable may touch the ground, affecting its lifespan. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a wire protection plug for converting folding bicycles into electric vehicles.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a wire protection plug for folding bicycles converted into electric vehicles: it includes a plug body and a wire hole provided in the plug body. The plug body includes an insertion part and an exposed part fixed at the lower end of the insertion part. The insertion part is cylindrical and its diameter is matched with the inner diameter of the lower end of the bicycle seat. The upper contour dimension of the exposed part is greater than or equal to the contour dimension of the lower end of the bicycle seat.

[0006] The threading hole is introduced from the upper end of the insertion part and led out from the upper side of the exposed part, and the threading hole transitions in an arc shape at the change position.

[0007] Furthermore, the main body of the plug is provided with a limiting groove 1 and a limiting groove 2. The limiting groove 1 communicates with the through hole, and the limiting groove 2 communicates with the limiting groove 1. One side of the insertion part is provided with a groove 1 communicating with the limiting groove 2, and the exposed part is provided with a groove 2. The through hole, limiting groove 1, limiting groove 2, and groove 1 are all connected to groove 2. A baffle is inserted into the limiting groove 1. An upper slider and a lower slider are slidably connected in the limiting groove 2. The upper slider is provided with an upper wedge, and the lower slider is provided with a lower wedge. The upper slider and the lower slider are provided with mutually cooperating connecting holes, thereby connecting them by connecting bolts. The lower wedge is located in the first groove and its outer side is matched with the outer side of the insertion part. The second groove is provided with an adjusting block, which is located between the upper and lower wedges. The adjusting block has limiting parts on both sides. The insertion part is located in a sliding groove that matches the limiting parts. The limiting parts slide horizontally relative to the sliding groove. The insertion part, the upper wedge, the lower wedge, and the adjusting block together form a cylinder. The second groove is provided with a pressure block that matches it. The pressure block has a notch near the wire hole. The pressure block is fixedly connected to the pipe plug body. The pressure block has a through-hole that is aligned with the connecting bolt.

[0008] Furthermore, the side of the baffle near the wire hole is sanded, while the other side is smooth.

[0009] Furthermore, the adjusting block has an anti-slip structure on its opposite outer side.

[0010] The advantages of this utility model compared with the prior art are as follows: This utility model is applied to situations where the power cord is arranged inside the bicycle seat post, so that most of the power cord is not exposed after the bicycle is converted into an electric bicycle, which improves the aesthetics. Through the cooperation of the wire hole and the baffle, the power cord is prevented from swinging around. When the seat post is pressed down during the bicycle folding process, the power cord at the lower end of the seat post will not touch the ground, extending the service life of the power cord. Moreover, without cutting the wire and re-soldering the plug, the wire protection and expansion fixation functions can be achieved. The installation is convenient and does not affect the overall aesthetics of the bicycle. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Example 1, referring to Figures 1-5, a protective plug for the power cord of a folding bicycle converted into an electric vehicle includes a plug body and a wire hole 1 disposed in the plug body. The plug body includes an insertion part 2 and an exposed part 3 fixed at the lower end of the insertion part 2. The insertion part 2 is cylindrical and its diameter is matched with the inner diameter of the lower end of the bicycle seat post. The upper contour dimension of the exposed part 3 is greater than or equal to the contour dimension of the lower end of the bicycle seat post. The purpose of the greater dimension is to provide a limit to prevent the seat post from being directly pushed out from the top.

[0020] The threading hole 1 is introduced from the upper end of the insertion part 2 and led out from the upper side of the exposed part 3, and the threading hole 1 has an arc transition at the change position.

[0021] In use, thread the power cord through the threading hole 1. The power cord will contact the inner wall of the threading hole 1, creating a certain amount of friction. A certain amount of force is required to pull the power cord relative to the pipe plug body. Tie a cable tie to the power cord above and near the pipe plug body. Adjust the power cord according to the actual needs so that the length of the power cord on both sides of the pipe plug body meets the actual requirements. Then move the cable tie to the upper side of the pipe plug body, tighten the cable tie and cut off the excess part of the cable tie so that the threading hole cannot be pulled out from below the pipe plug body. Then insert the insertion part 2 into the lower end of the seat rod and fix it.

[0022] In this specific embodiment, the plug body is provided with a limiting groove 4 and a limiting groove 5. The limiting groove 4 communicates with the through hole 1, and the limiting groove 5 communicates with the limiting groove 4. The insertion part 2 is provided with a groove 6 communicating with the limiting groove 5 on one side. The exposed part 3 is provided with a groove 7. The through hole 1, the limiting groove 4, the limiting groove 5, and the groove 6 are all connected to the groove 7. A baffle 8 is inserted into the limiting groove 4. An upper slider 9 and a lower slider 10 are slidably connected in the limiting groove 5. The upper slider 9 is provided with an upper wedge 11, and the lower slider 10 is provided with a lower wedge 12. The upper slider 9 and the lower slider 10 are provided with mutually cooperating connecting holes 13, thereby connecting them by connecting bolts. The upper wedge 11 and the lower wedge 12 are connected by connecting bolts. The shaped component 12 is located in the first groove 6 and its outer side is adapted to the outer side of the insertion part 2. The second groove 7 is provided with an adjusting block 14, which is located between the upper wedge 11 and the lower wedge 12. The adjusting block 14 is provided with limiting parts 15 on both sides. The insertion part 2 is provided in a sliding groove 16 adapted to the limiting part 15. The limiting part 15 slides horizontally relative to the sliding groove 16. The insertion part 2, the upper wedge 11, the lower wedge 12, and the adjusting block 14 together form a cylinder. The second groove 7 is provided with a pressure block 17 adapted to it. The pressure block 17 is provided with a notch near the wire hole 1. The pressure block 17 is fixedly connected to the pipe plug body. The pressure block 17 is provided with a through insertion hole 18, which is aligned with the connecting bolt. This structural design allows the wire to be inserted into the wire hole 1 from the side without cutting it. This is then combined with other structures to seal the wire hole 1 (the wire is connected to the motor; the cut end has a plug, so it cannot be inserted from top to bottom). In use, insert the baffle 8 into the groove 6 to limit the power cord. A certain amount of force is required to move the power cord relative to the pipe plug body. Insert the upper slider 9 and lower slider 10, press the adjusting block 14 in from the side, and press the pressure block 17 in from below to fix it to the pipe plug body. Adjusting the power cord is done in the same way. After tightening the cable tie and removing the excess, insert the insertion part 2 into the lower end of the seat post for fixation. Using a screwdriver or similar tool inserted through the insertion hole 18 can push the upper slider 9 and lower slider 10 upwards relative to each other. Under the action of the upper wedge 11 and lower wedge 12, the adjusting block 14 expands outwards, further increasing the friction between the pipe plug body and the seat post, making it less prone to loosening.

[0023] In this specific embodiment, the side of the baffle 8 near the wire hole 1 is sanded to increase the coefficient of friction with the power cord, so that a certain force is required to pull the power cord, while the other side is smooth.

[0024] In this specific embodiment, the adjusting block 14 is provided with an anti-slip structure 19 on its outer side to increase the coefficient of friction with the inner side of the seat rod, making it less prone to loosening.

[0025] In this specific embodiment, the anti-slip structure 19 is an anti-slip tooth or anti-slip pattern. Of course, the anti-slip structure 19 can also adopt other forms of anti-slip design, which are not limited here.

[0026] In this specific embodiment, the exposed portion is in the shape of an inverted frustum, which is aesthetically pleasing.

[0027] In this specific embodiment, the pressure block 17 and the pipe plug body are fixedly connected by fixing bolts.
