Description

Technical Field

[0001] The utility model relates to the technical field of electric power-assisted bicycle parts, in particular to a wiring box for an electric power-assisted bicycle. Background Art

[0002] The junction box of an electric power-assisted bicycle is a device used for circuit connection and management. In an electric power-assisted bicycle, there are usually multiple electronic components, such as electric motors, batteries, controllers, etc. These components need to be connected together through wires, and the junction box is used to conveniently gather these wires together to achieve the purpose of storage and organization.

[0003] The existing junction boxes of electric power-assisted bicycles are mostly box-shaped with a fixed size. A wire fixing structure is arranged inside the box body to gather and fix a section of the wire inside the box body. In actual use, since electric power-assisted bicycles are of different sizes and shapes, the length of the wires that need to be gathered is also not fixed. If the junction box is too long, the space occupied by the electric power-assisted bicycle will be increased, and if it is too small, the wire gathering effect will be unsatisfactory. Moreover, the box body is wrapped around the wires, which will affect the heat dissipation of the wires. In addition, when the wires pass through the junction box, the wires will be squeezed and worn against the box wall due to bending, and long-term use will cause damage to the wires. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a wiring box for an electric assisted bicycle, comprising a pull-out seat, a wire fixing ring and a support bent plate. The pull-out seats are of several numbers and are rotatably connected in sequence. The pull-out seats at both ends are connected by a fixed structure. The pull-out seat comprises a fixed seat and a movable seat. One end of the movable seat is slidably arranged in the fixed seat, and a positioning structure is connected on both sides of the fixed seat. The wire fixing ring is respectively arranged on the front sides of the fixed seat and the movable seat, away from each other at one end. The wire fixing ring comprises a symmetrically arranged wire fixing plate, one end of the wire fixing plate is rotatably connected to the fixed seat and the movable seat, and the other end of the wire fixing plate is connected by a fixed structure. The support bent plate is slidably arranged on the side away from each other of the wire fixing ring, a fixing belt is connected to the inner side of the support bent plate, a Velcro hook surface is provided on the end of the fixing belt, and a Velcro fur surface is connected at the inner edge of the support bent plate.

[0006] Furthermore, the positioning structure includes an elastic rod, a pull plate and a positioning column. The pull plate is fixed on the side wall of the fixed seat through the elastic rod. The positioning column is arranged on the lower end of the pull plate close to the movable seat. The side wall of the movable seat is provided with a plurality of positioning holes matching the positioning columns.

[0007] Furthermore, a protrusion flush with the front side wall of the fixed seat is integrally formed on the front side of the movable seat, and the wire fixing ring is fixed on the protrusion.

[0008] Furthermore, the fixing structure includes a fixing block and bolts. The fixing block is fixed to two side walls of the fixing seat and the end of the wire fixing plate that are far away from each other. Adjacent fixing blocks are connected by bolts.

[0009] Furthermore, a non-slip rubber pad is connected to the inner side of the wire fixing plate.

[0010] Furthermore, a slider is connected to the lower side of the support bent plate, and an annular groove matching the slider is provided on the wire fixing plate.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Adjustable wire bundling length: The design of the pull-out seat allows users to adjust the wire bundling length according to actual needs, making it more neat and compact, which is conducive to the effective management of the vehicle wiring harness and improving the aesthetics of the electric power-assisted bicycle.

[0013] Small wrapping range is conducive to heat dissipation: The design of the wire fixing ring and fixing belt can minimize the contact and coverage area of ​​the junction box to the wires while ensuring the firmness of the wires, which is conducive to the heat dissipation of the wires.

[0014] The wires can be bent, supported and protected: The design of the support bending plate can guide and bend the wires after they are detached from the wire fixing ring, avoiding damage caused by excessive bending at the contact point between the wires and the wire fixing ring. At the same time, the support bending plate can be rotated to facilitate the bending of the wires in different directions, which is flexible and practical. BRIEF DESCRIPTION OF THE DRAWINGS
