Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive wiring harness protection structure. Background Technology

[0002] Automotive wiring harnesses are circuit connection components formed by crimping copper terminals with wires and cables, then encasing them in insulation or a metal shell and bundling them together. They are the main transmission components of automotive circuits, and without wiring harnesses, a complete automotive circuit system cannot be formed. They are an important part of the automotive circuit system. During the installation of automotive wiring harnesses, positioning and protection components are required to position and protect the wiring harnesses.

[0003] Existing automotive wiring harness protection components have the following drawbacks: during the inspection and maintenance of internal automotive components, especially electrical components such as motors and displays, it is often necessary to pull and adjust the position of the wiring harness. Excessive force can easily cause the connection between the wiring harness and the electrical component to break or the wire to come out of its fixed position, increasing maintenance costs. To address this, we propose an automotive wiring harness protection structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a protective structure for automotive wiring harnesses. Through the protective mechanism set inside the sleeve, the wiring can be positioned well, and an early warning can be given when the wiring is pulled, so as to avoid the problem of disconnection or misalignment caused by excessive pulling of the wiring. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective structure for automotive wiring harnesses includes a sleeve and a protective mechanism. The protective mechanism is housed inside the sleeve and includes a sliding groove, a lower clamp, an upper clamp, a pull rod, an end ring, a spring, a hollow corrugated tube, and a whistle. The sleeve's inner wall has symmetrically arranged sliding grooves on both sides at its bottom, through which the lower clamp is slidably connected. The upper clamp is fitted to the top of the lower clamp, and the upper clamp has a pull rod fixedly connected to both sides of its end surface. The top of the pull rod extends to the outside of the sleeve, and the bottom of the pull rod passes through the lower clamp, with an end ring adhered to the bottom of the pull rod. A spring is installed between the end ring and the bottom of the lower clamp. Whistles are adhered to both sides of the bottom of the sleeve's inner wall, and hollow corrugated tubes are installed between the side of the lower clamp and the blowing end of the whistle.

[0007] Furthermore, it also includes an installation mechanism. The sleeve is provided with an installation mechanism on its side. The installation mechanism includes a mounting base, a slot, a limiting groove, a plastic plate, and a limiting block. The mounting base has a slot on its side, and limiting grooves are provided at both the upper and lower ends of the inner wall of the slot. The outer wall of the sleeve is integrally formed with a plastic plate, and the end of the plastic plate is integrally formed with a limiting block. The mounting end of the sleeve is equipped with a mounting base assembly. When laying the line, the mounting base is first fixed in a suitable position inside the vehicle body with fasteners. The mounting base has a slot and a limiting groove on its side. After the cable is clamped and positioned inside the sleeve, the limiting block on the side of the sleeve is aligned with the slot and inserted. During the insertion process, the plastic plate is slightly deformed by compression, so that the limiting block can be inserted smoothly. After insertion, the plastic plate resets so that the limiting block is just locked into the limiting groove, thus completing the fixation of the sleeve position.

[0008] Furthermore, a slider is slidably connected inside the groove, and a connecting rod is integrally formed on the top of each slider and connected to the bottom of the lower clamping seat through the connecting rod; the bottom of the lower clamping seat is connected to the groove at the bottom of the inner wall of the sleeve through the slider. When the upper clamping seat is moved, the lower clamping seat can also move smoothly with the upper clamping seat through the cooperation of the groove and the slider.

[0009] Furthermore, each of the hollow corrugated tubes is provided with an air inlet and outlet pipe at the end facing the whistle, and the end of the air inlet and outlet pipe is fitted into the outer periphery of the blowing end of the whistle; when the hollow corrugated tube is squeezed, the internal air is blown into the whistle through the air inlet and outlet pipe, and when the hollow corrugated tube is reset, the external air enters the hollow corrugated tube from the whistle.

[0010] Furthermore, the top of the sleeve is symmetrically provided with through slots on both sides, and the top of the pull rod extends through the through slot to the outside of the sleeve; the top of the pull rod extends through the through slot at the top of the sleeve, making it easy to pull, while the through slot can limit the pulling range of the pull rod, thereby limiting the movement range of the upper clamp and the lower clamp.

[0011] Furthermore, screw holes are provided at the four corners of the mounting base, and the limiting block corresponds to the limiting groove and is inserted into the limiting groove; the screw hole structure facilitates the use of fasteners to fix the mounting base in a suitable installation position, and the cooperation between the limiting groove and the limiting block realizes the fixation between the sleeve and the mounting base.

[0012] Compared with the prior art, this utility model has the following advantages: Symmetrical lower and upper clamping structures are provided on both sides of the sleeve. In the unused state, the bottom of the upper clamping seat is attached to the surface of the lower clamping seat. When laying cables inside the vehicle, the sleeve is fixed near electrical components or main wiring locations. Then, the pull rods on both sides are pulled up sequentially. Pulling the pull rods compresses the springs, causing the upper and lower clamping seats to separate. The wire harness passes between the lower and upper clamping seats. Then, the pull rods are released, and the springs cause the upper clamping seat to reset and cooperate with the lower clamping seat to clamp and fix the wire harness. Both clamping seat assemblies clamp the wire harness, and a certain length of the wire harness is reserved between the clamping seats, allowing it to bend between the clamping seats. The end of the wire harness exits from the end of the sleeve, thus completing the connection between the wire harness and the sleeve. When it is necessary to pull the wire harness during vehicle wiring harness maintenance, the lower and upper clamping seats cooperate to clamp the outer periphery of the wire harness. Excessive pulling on the wire harness will cause the lower and upper clamps to move towards the end of the sleeve. When the lower clamp moves, it will squeeze the hollow corrugated tube. During the squeezing, the air inside will be squeezed out and blown into the whistle, emitting a whistling sound to remind personnel to stop pulling. This avoids the problem of the wire connection end or fixed end falling off due to excessive pulling, effectively protecting the wire harness and reducing the problem of wire harness falling off during vehicle maintenance. The side of the sleeve is equipped with a mounting bracket assembly. When laying the wire, the mounting bracket is first fixed in a suitable position inside the vehicle body with fasteners. The side of the mounting bracket has a slot and a limiting slot. After the cable is clamped and positioned inside the sleeve, the limiting block on the side of the sleeve is aligned with the slot and inserted. During the insertion process, the plastic plate is squeezed and slightly deformed, allowing the limiting block to be inserted smoothly. After insertion, the plastic plate returns to its original position, so that the limiting block is just locked into the limiting slot, thus completing the fixation of the sleeve position.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a protective structure for automotive wiring harnesses includes a sleeve 1 and a protective mechanism 2. The protective mechanism 2 is disposed inside the sleeve 1. The protective mechanism 2 includes a sliding groove 201, a lower clamp 204, an upper clamp 205, a pull rod 206, an end ring 207, a spring 208, a hollow corrugated tube 209, and a whistle 210. The bottom sides of the inner wall of the sleeve 1 are symmetrically provided with sliding grooves 201, and the lower clamp 204 is slidably connected to the sliding grooves 201. The top of the lower clamp 204 is provided with an upper clamp 210. The upper clamp 205 has a pull rod 206 fixedly connected to both the upper and lower sides of the end surface of the upper clamp 205. The top of the pull rod 206 extends to the outside of the sleeve 1. The bottom of the pull rod 206 passes through the lower clamp 204 and the bottom of the pull rod 206 is glued with an end ring 207. A spring 208 is installed between the end ring 207 and the bottom of the lower clamp 204. Whistles 210 are glued to both sides of the bottom of the inner wall of the sleeve 1. Hollow corrugated tubes 209 are installed between the side of the lower clamp 204 and the blowing end of the whistle 210.

[0020] This also includes an installation mechanism 3. The sleeve 1 has an installation mechanism 3 on its side. The installation mechanism 3 includes a mounting base 301, a slot 303, a limiting groove 304, a plastic plate 305, and a limiting block 306. The mounting base 301 has a slot 303 on its side, and limiting grooves 304 are formed at both the upper and lower ends of the inner wall of the slot 303. The outer wall of the sleeve 1 has a plastic plate 305 integrally formed on its side, and limiting blocks 306 are integrally formed at the ends of the plastic plate 305. The mounting end of the sleeve 1 is equipped with a mounting base 301 assembly for wiring. First, the mounting base 301 is fixed in a suitable position inside the vehicle body using fasteners. The mounting base 301 has a slot 303 and a limiting slot 304 on its side. After the cable is clamped and positioned inside the sleeve 1, the limiting block 306 on the side of the sleeve 1 is aligned with the slot 303 and inserted. During the insertion process, the plastic plate 305 is slightly deformed by compression, so that the limiting block 306 can be inserted smoothly. After insertion, the plastic plate 305 is reset so that the limiting block 306 is just inserted into the limiting slot 304, thus completing the fixation of the sleeve 1.

[0021] The slide groove 201 is slidably connected to a slider 202. The top of the slider 202 is integrally formed with a connecting rod 203, which is connected to the bottom of the lower clamp 204. The bottom of the lower clamp 204 is connected to the slide groove 201 at the bottom of the inner wall of the sleeve 1 through the slider 202. When the upper clamp 205 is moved, the lower clamp 204 can also move smoothly with the upper clamp 205 through the cooperation of the slide groove 201 and the slider 202.

[0022] The hollow corrugated tube 209 is provided with an air inlet and outlet pipe 211 at the end facing the whistle 210. The end of the air inlet and outlet pipe 211 is fitted into the outer periphery of the blowing end of the whistle 210. The top of the sleeve 1 is symmetrically provided with through slots 212 on both sides. The top of the pull rod 206 extends through the through slot 212 to the outside of the sleeve 1. When the hollow corrugated tube 209 is squeezed, the internal air is blown into the whistle 210 through the air inlet and outlet pipe 211. When the hollow corrugated tube 209 is reset, the external air enters the hollow corrugated tube 209 through the whistle 210. The top of the pull rod 206 extends through the through slot 212 at the top of the sleeve 1, so that the top of the pull rod 206 extends to the outside of the sleeve 1, which is convenient for pulling. At the same time, the through slot 212 can limit the pulling range of the pull rod 206, thereby limiting the movement range of the upper clamp 205 and the lower clamp 204.

[0023] The mounting base 301 has screw holes 302 at each of its four corners. The limiting block 306 corresponds to the limiting groove 304 and is inserted into the limiting groove 304. The screw hole 302 structure allows for convenient and practical fastener fixation of the mounting base 301 in a suitable installation position. The cooperation between the limiting groove 304 and the limiting block 306 achieves the fixation between the sleeve 1 and the mounting base 301.

[0024] It should be noted that this utility model is a protective structure for automotive wiring harnesses. In use, the sleeve 1 has symmetrical lower clamps 204 and upper clamps 205 on both sides inside. When not in use, the bottom of the upper clamp 205 is attached to the surface of the lower clamp 204. During cable routing inside the vehicle, the sleeve 1 is fixed near electrical components or main wiring locations. Then, the pull rods 206 on both sides are pulled upwards. Pulling the pull rods 206 compresses the spring 208, causing the upper clamp 205 to separate from the lower clamp 204. The wire harness is inserted between the lower clamp 204 and the upper clamp 205. Then, the pull rod 206 is released, and the spring 208 drives the upper clamp 205 to return to its original position, cooperating with the lower clamp 204 to clamp and fix the wire harness. Both clamp assemblies on both sides clamp the wire harness, and a certain length of the wire harness is reserved between the clamps, so that it is bent between the clamps. The end of the wire harness is discharged from the end of the sleeve 1, thus completing the connection between the wire harness and the sleeve 1. When it is necessary to pull the wire harness during the maintenance of the automotive wire harness, the lower clamp 204 and the upper clamp 205 cooperate to clamp the wire harness. If the wiring harness is pulled excessively, the lower clamp 204 and upper clamp 205 will move towards the end of the sleeve 1. When the lower clamp 204 moves, it will squeeze the hollow corrugated tube 209. During the squeezing, the air inside will be squeezed out and blown into the whistle 210 to make a whistling sound, reminding personnel to stop pulling. This avoids the problem of the wiring connection end or fixed end falling off due to excessive pulling, effectively protecting the wiring harness and reducing the problem of wiring harness falling off during vehicle maintenance. The side mounting end of the sleeve 1 is equipped with a mounting base 301 assembly. When laying the wiring, First, fix the mounting base 301 in a suitable position inside the vehicle body using fasteners. The mounting base 301 has a slot 303 and a limiting groove 304 on its side. After the cable is clamped and positioned inside the sleeve 1, align the limiting block 306 on the side of the sleeve 1 with the slot 303 and insert it. During the insertion process, the plastic plate 305 is squeezed and slightly deformed, so that the limiting block 306 can be inserted smoothly. After the insertion is in place, the plastic plate 305 resets so that the limiting block 306 is just locked into the limiting groove 304, thus completing the fixation of the sleeve 1.
