Description

Technical Field

[0001] The utility model belongs to the technical field of automotive wiring harnesses, and particularly relates to a wiring harness protection structure. Background Art

[0002] A wiring harness is the core carrier of the control system in an automobile, generally formed by wrapping one or more strands of cables with a wire sheath. At present, in the automotive field, for the protection of wiring harnesses, a corrugated pipe or other similar pipe body is usually used to wrap and hide the wiring harness, so as to reduce the effects of external loads, extrusion, etc. However, the wiring harness in the protection pipe cannot be isolated. On the one hand, it is easy to cause the wiring harness to be entangled and interfere with each other. If the wiring harness is stressed for a long time during the entanglement process, it may cause the wiring harness to break. On the other hand, during the later maintenance process, it is extremely inconvenient to find the problem circuit due to various wiring harnesses being mixed together. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a wiring harness protection structure to solve the technical problem that the wiring harness in the existing protection pipe cannot be isolated.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A wiring harness protection structure includes a square tubular bracket with an opening on one side. Isolation units are arranged at intervals on the inner wall of the bracket. The isolation unit includes a "C"-shaped mounting seat. The opening direction of the mounting seat faces the central axis of the bracket. Accommodation grooves are opened on both sides of the bottom plate of the mounting seat. The extending direction of the accommodation groove is the same as the extending direction of the mounting seat. A fixed shaft extending in the same direction is arranged in the accommodation groove. A sleeve is rotatably connected to the fixed shaft. There is a gap between the side surface of the sleeve and the accommodation groove. A limiting plate is fixedly connected to the outer side surface of the part of the sleeve exposed outside the accommodation groove. The limiting plate rotates around the fixed shaft with the sleeve. An elastic element is arranged between the back surface of the limiting plate and the side plate of the mounting seat;

[0006] Further, the sleeve is sleeved outside the fixed shaft. The inner diameter of the sleeve is the same as the diameter of the fixed shaft. The length of the sleeve is the same as the length of the fixed shaft;

[0007] Further, the elastic element adopts a spring. One end of the spring is fixed to the inner wall of the side plate of the mounting seat, and the other end of the spring is fixed to the back surface of the limiting plate;

[0008] Further, a wiring hole is opened on the bracket. The connection hole is staggered from the mounting seat. An extension ring is communicated with the outside of the connection hole. A cap is arranged at the free end of the extension ring;

[0009] Further, a chute is opened at the opening of the bracket. A sealing plate is slidably connected in the chute to close the opening of the bracket;

[0010] Furthermore, a corner limiting unit is provided at the corner of the support. The corner limiting unit includes a connecting shaft between the top plate and the bottom plate of the support. The connecting shaft extends vertically and a limiting cylinder is rotatably connected to the connecting shaft. There are gaps between the two ends of the limiting cylinder and the top plate and the bottom plate of the support, respectively. The outer diameter of the limiting cylinder gradually decreases from the two ends to the middle.

[0011] Furthermore, two corner limiting units are provided and are distributed at intervals along the diagonal direction at the corner of the bracket. The inner corner limiting unit forms a first channel with the side wall of the bracket, and the wire harness fixed on the side wall of the bracket passes through the first channel. The two corner limiting units form a second channel, and the wire harness fixed on the top wall and bottom plate of the bracket passes through the second channel.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) Compared with the prior art, by setting up an isolation unit, the wire harnesses with different functions and roles are isolated inside the bracket. On the one hand, it not only avoids the tangling between wire harnesses, but also effectively prevents the wire harnesses from interfering with each other. On the other hand, in the later maintenance process, it can quickly find and accurately identify the problem line, which greatly facilitates the maintenance process and significantly improves the maintenance efficiency.

[0014] (2) By setting the corner limiting unit, on the one hand, the wire harness can be isolated, and on the other hand, the wire harness can be limited to prevent the wire harness from moving to the inside of the corner and contacting the sealing plate, thus avoiding wear of the sealing plate on the wire harness; in addition, the limiting cylinder 302 rotates under the action of the wire harness, reducing the friction between the limiting cylinder and the wire harness and ensuring the service life of the wire harness.

Specific embodiments

[0026] Embodiment 1, specifically as Figures 1-8 shown.

[0027] A wire harness protection structure includes a square tubular bracket 1 with one side open, an isolation unit 2 is arranged at intervals on the inner wall of the bracket 1, and a corner limiting unit 3 is arranged at the corner of the bracket 1.

[0028] As Figure 1 shown, isolation units 2 are arranged on the top wall, bottom plate and side wall of the bracket 1. The isolation units 2 in the three directions can be either on the same cross-section or staggered from each other. In this embodiment, the isolation units 2 in the three directions are on the same cross-section, which is beneficial to the synchronous installation of multiple wire harnesses.

[0029] The isolation unit 2 includes a "C"-shaped mounting seat 201. The opening direction of the mounting seat 201 faces the central axis of the bracket 1. The mounting seat 201 and the bracket 1 are fixedly connected by welding or screws. Receiving grooves 202 are opened on both sides of the bottom plate of the mounting seat 201. The extending direction of the receiving grooves 202 is the same as the extending direction of the mounting seat 201. Fixed shafts 203 extending in the same direction are arranged in the receiving grooves 202. The fixed shafts 203 are located at the openings of the receiving grooves 202 and the two ends of the fixed shafts 203 are fixedly welded to the groove walls of the receiving grooves 202. A sleeve 204 is rotatably connected to the fixed shafts 203. Specifically, the sleeve 204 is sleeved around the fixed shafts 203. The inner diameter of the sleeve 204 is the same as the diameter of the fixed shafts 203, and the length of the sleeve 204 is the same as the length of the fixed shafts 203. It is necessary to further explain that a part of the sleeve 204 extends out of the receiving groove 202, and there is a gap between the side surface of the sleeve 204 and the receiving groove 202, that is, the sleeve 204 will not interfere with the receiving groove 202 during rotation.

[0030] A limiting plate 205 is fixedly connected to the outer surface of the sleeve 204 protruding from the receiving groove 202. The limiting plate 205 rotates with the sleeve 204 around the fixed shaft 203. An elastic element 206 is provided between the back of the limiting plate 205 and the side plate of the mounting base 201. The elastic element 206 provides elastic support for the limiting plate 205. The elastic elements 206 are distributed at intervals along the extension direction of the mounting base 201. In this embodiment, the elastic element 206 is a spring. One end of the spring is welded and fixed to the inner wall of the side plate of the mounting base 201, and the other end of the spring is welded and fixed to the back of the limiting plate 205.

[0031] In its natural state, the two limiting plates 205 are tilted relative to each other, and the two limiting plates 205 and the base plate of the mounting base 201 together form a wire harness clamping space. In use, the wire harness is inserted into the top opening of the wire harness clamping space. The wire harness is fully inserted into the wire harness clamping space. At this time, the two limiting plates 205 rotate in the direction away from the wire harness due to the force of the wire harness. The elastic element 206 is compressed synchronously. The elastic element 206 applies a reaction force to the wire harness, so that the two limiting plates 205 squeeze the wire harness, thereby fixing the wire harness.

[0032] By setting up isolation unit 2, wire harnesses with different functions and roles are isolated inside bracket 1. On the one hand, this not only avoids tangling between wire harnesses, but also effectively prevents interference between them. On the other hand, during later maintenance, it enables quick and accurate identification of problematic lines, greatly facilitating the maintenance process and significantly improving maintenance efficiency.

[0033] like Figure 1 As shown, the bracket 1 has a wiring hole 101, which is offset from the mounting base 201. An extension ring 102 is connected to the outside of the wiring hole 101, and the extension ring 102 is welded to the bracket 1. By providing the wiring hole 101 and the extension ring 102, it is convenient for the wire harness to pass through the corresponding part for wiring operations. A cap 103 is provided on the free end of the extension ring 102, and the cap 103 is threadedly connected to the extension ring 102. Specifically, the outer surface of the free end of the extension ring 102 has an external thread, and the side wall of the cap 103 has an internal thread. The cap 103 seals the wiring hole 101, which to a certain extent prevents external contaminants from damaging the wire harness inside the bracket 1.

[0034] A groove 104 is provided at the opening of the bracket 1, and a sealing plate 105 is slidably connected in the groove 104. The sealing plate 105 closes the opening of the bracket 1. The opening facilitates the installation and disassembly of the wire harness. The sealing plate 105 closes the opening of the bracket 1, improves the structural stability of the bracket 1, and protects the wire harness inside the bracket 1.

[0035] In actual use, bracket 1 needs to be bent according to the installation environment. However, isolation unit 2 cannot usually be set at the bend. As a result, during use, the wire harness will move towards the inside of the corner and come into contact with the sealing plate 105. In severe cases, the sealing plate 105 at the corner will cause wear to the wire harness, affecting the normal operation and service life of the wire harness.

[0036] Based on this, a corner limiting unit 3 is provided at the corner of bracket 1, such as Figures 6-8 As shown, the corner limiting unit 3 includes a connecting shaft 301 disposed between the top plate and the bottom plate of the bracket 1. The connecting shaft 301 extends vertically, and its two ends are welded and fixed to the top plate and the bottom plate of the bracket 1, respectively. A limiting cylinder 302 is rotatably connected to the connecting shaft 301. There are gaps between the two ends of the limiting cylinder 302 and the top plate and the bottom plate of the bracket 1, respectively. The outer diameter of the limiting cylinder 302 gradually decreases from the two ends to the middle.

[0037] The limiting sleeve 302 is sleeved around the connecting shaft 301. The inner diameter of the limiting sleeve 302 is larger than the diameter of the connecting shaft 301. The limiting sleeve 302 and the connecting shaft 301 are rotatably connected by bearings 303. The bearings 303 are spaced apart along the length of the connecting shaft 301. The inner ring of the bearing 303 is interference-fitted with the connecting shaft 301, and the outer ring of the bearing 303 is interference-fitted with the limiting sleeve 302.

[0038] It is worth emphasizing that in this embodiment, there are two corner limiting units 3, which are distributed at intervals along the diagonal direction of the corner of the bracket 1. The inner corner limiting unit 3 forms a first channel with the side wall of the bracket 1, and the wire harness fixed on the side wall of the bracket 1 passes through the first channel. The two corner limiting units 3 form a second channel, and the wire harness fixed on the top wall and bottom plate of the bracket 1 passes through the second channel.

[0039] By setting the corner limiting unit 3, the wire harness can be isolated on the one hand, and limited on the other hand, to prevent the wire harness from moving inward to the corner and coming into contact with the sealing plate 105, thus avoiding wear caused by the sealing plate 105. In addition, the limiting cylinder 302 rotates under the action of the wire harness, reducing the friction between the limiting cylinder 302 and the wire harness and ensuring the service life of the wire harness.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
