Description
Technical Field
[0001] This utility model relates to the field of wire harness fixing, specifically to a battery pack wire harness fixing buckle device. Background Technology
[0002] With the continuous development of autonomous driving and intelligent connected vehicle technologies and the application of 5G technology, the number of electrical functions in vehicles is increasing, leading to a greater number of electrical functions that wiring harnesses need to connect. At the same time, the space for wiring harness arrangement is becoming increasingly limited, and the environment is becoming increasingly harsh. As the core power source of new energy electric vehicles, the battery pack's internal wiring harness is also subject to this challenge. During the wiring harness arrangement design process, it is crucial to quickly select appropriate fasteners for different environments to ensure the safety and reliability of the battery pack wiring harness. There are many types of wiring harness clips, commonly including T-type clips, L-type clips, pipe clamp clips, and connector clips. Different types of clips are suitable for different installation scenarios. The main function of wiring harness clips is to fix the wiring harness, preventing it from loosening or shifting, thereby avoiding damage or short circuits caused by vibration, friction, etc. Furthermore, the design of the clips must also meet the wiring harness routing control requirements to ensure that the wiring harness does not interfere with other components, while reducing noise and wear. This patent aims to more conveniently and quickly fix the internal wiring harness of the battery pack, making the battery pack more securely fixed.
[0003] At present, a battery pack wiring harness fixing clip is proposed to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a battery pack wiring harness fixing buckle, which makes it easier and faster to fix the internal wiring harness of the battery pack, and makes the battery pack more secure. This solves the problem that the current wiring harness buckles are complicated in type and are troublesome to use and find.
[0005] The technical solution of this utility model is as follows:
[0006] A battery pack wiring harness fixing buckle device includes a buckle housing and a buckle connecting rod. The buckle housing is hollow inside, and a wiring harness limiting device is detachably disposed inside the buckle housing. The buckle connecting rod is installed below the buckle housing for fixing to the battery pack housing. The buckle housing is provided with a wiring harness hole for the wiring harness to pass through.
[0007] Furthermore, the buckle connecting rod is provided with an external thread, the battery pack housing is provided with a threaded hole, and the external thread on the buckle connecting rod matches the internal thread in the threaded hole.
[0008] Furthermore, the wire harness limiting device is a needle roller, and there are two needle rollers, which are detachably installed on the left and right sides inside the buckle housing, respectively, and the wire harness hole passes through the front and rear sides of the buckle housing.
[0009] Further defined, the needle roller includes a limiting part, an upper mounting part, and a lower mounting part, all of which are cylindrical, and their center lines are all on the same straight line.
[0010] Furthermore, the upper and lower end faces of the buckle housing are symmetrically provided with a plurality of limiting holes, the diameter of the limiting holes being matched with the outer diameter of the upper mounting part and the lower mounting part, and the upper mounting part and the lower mounting part of the needle roller being located in the limiting holes of the upper end face and the lower end face, respectively.
[0011] Further specifying, the buckle housing is made of flexible material, and slots are provided on both the left and right side walls of the buckle housing. The positions of the slots correspond to the limiting part of the needle roller, and the wire harness hole is an elliptical hole.
[0012] The advantages of this utility model over the current technology are as follows:
[0013] 1. The buckle housing is made of flexible material. Several limiting holes are symmetrically arranged on the upper and lower end faces of the buckle housing. The upper mounting part and the lower mounting part are respectively located in the limiting holes on the upper and lower end faces. The left and right side walls of the buckle housing are provided with slots. By pushing the limiting part by hand, the needle roller can be adjusted to different limiting holes, thereby achieving the purpose of adjusting the buckle according to the wire harness. The adjustment is relatively convenient.
[0014] 2. The wire harness passes through the oval wire harness hole on the buckle housing, and the roller can rotate freely around the central axis, thereby reducing the friction on the wire harness surface when the wire harness passes through. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example
[0019] like Figure 1 and Figure 2 As shown, a battery pack wiring harness fixing buckle device includes a buckle housing 1 and a buckle connecting rod 2. The buckle connecting rod 2 is provided with an external thread 3, and the battery pack housing is provided with a threaded hole. The threaded hole is provided with an internal thread, and the external thread 3 and the internal thread are matched. The buckle connecting rod 2 is installed in the threaded hole of the battery pack housing through a threaded connection. The buckle housing 1 is hollow inside, and a wiring harness limiting device is provided inside the buckle housing 1. The wiring harness limiting device is a needle roller 4. There are two needle rollers 4, located on the left and right sides inside the buckle housing 1, respectively. The needle roller 4 includes a limiting part 41, an upper mounting part 42, and a lower mounting part 43. The upper mounting part 42, the lower mounting part 43, and the limiting part 41 are all cylindrical. The center lines of all parts 41 are on the same straight line. Several limiting holes 5 are symmetrically arranged on the upper and lower end faces of the buckle housing 1. The limiting holes 5 are interconnected. The diameter of the limiting holes 5 matches the outer diameter of the upper mounting part 42 and the lower mounting part 43. The upper mounting part 42 and the lower mounting part 43 of the needle roller 4 are located in the limiting holes 5 on the upper end face and the lower end face, respectively. The buckle housing 1 is made of flexible materials such as polytetrafluoroethylene and also has good insulation. Elliptical wire harness holes 6 for wire harnesses to pass through are provided on the side walls of the front and rear sides of the buckle housing 1. The left and right side walls of the buckle housing 1 are provided with slots 7. The position of the slots 7 corresponds to the limiting part 41 of the needle roller 4. The width of the slots 7 is greater than the diameter of the limiting part 41.
[0020] In use, the wire harness passes through the elliptical wire harness hole 6 on the snap-fit housing 1. The roller needle 4 can rotate freely around the central axis to reduce friction on the wire harness surface when it passes through. When wire harnesses of different outer diameters need to pass through, the distance between the two roller needles 4 needs to be adjusted. Since the upper and lower sections of the snap-fit housing 1 are symmetrically provided with several limiting holes 5, and the limiting holes 5 are interconnected, the upper mounting part 42 and the lower mounting part 43 of the roller needle 4 are located in the limiting holes 5 on the upper end face and the lower end face, respectively. Moreover, the snap-fit housing 1 is made of flexible material, so the roller needle 4 can be moved to the limiting hole 5 at different positions by pressing the limiting part 41 of the roller needle 4 with a finger through the slot 7, thereby changing the distance between the two roller needles 4 and thus accommodating wire harnesses of different sizes.
[0021] The above provides a detailed description of a battery pack wiring harness fixing buckle device provided by this utility model. The description of the specific embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the present utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
