Description

TECHNICAL FIELD

[0001] The utility model belongs to the pipeline road field, concretely relates to a detachable support structure for wiring harness fixing. BACKGROUND

[0002] The wiring harness fixing structure is a structure for wiring harness support, fixing and gap adjustment, which plays a role in fixing wiring harness direction and optimizing wiring harness fixing spacing. When the pipeline is arranged on the frame, it needs to be fixed within a specified length range. The pipeline fixing structure serves as a medium connecting the pipeline and the vehicle body, ensuring that the pipeline and the vehicle body do not move relative to each other during vehicle driving. Patent CN202222297619.6 discloses a wiring harness support and a vehicle with the same, wherein a plurality of wiring harness supports are arranged at intervals in the length direction of the frame, and the cable passes through the wiring harness supports and is bundled with the wiring harness supports. However, in this structure, a plurality of wiring harness supports need to be provided by welding or other means, and about 10 wiring harness supports are needed within a distance of 1 meter, otherwise the part of the wiring harness not placed on the support will sag. The current wiring harness fixing of various engineering vehicles such as rigid trucks and mining trucks usually adopts a fixing structure of cable tie + welded cable pipe. The above structure has the following disadvantages: ① The cable pipe for fixing the wiring harness is welded on the frame, and since the frame is generally long, a large number of supports need to be welded, resulting in low welding efficiency of the whole vehicle; ② Due to the large number of welded cable pipes, the appearance of the frame pipeline is not good; ③ During subsequent maintenance, if the cable pipe falls off, it is difficult to repair and maintain. Patent CN218976210U discloses a vehicle pipeline wiring harness rod and a vehicle, which includes a long rod body, and the wiring harness is fixed on the rod body. In both the existing technology and the new technical solution, the structure of the rod body changes, but the fixing method does not change, and the rod body is set on the frame by welding at both ends or welding at other positions. Once the rod body is damaged after welding, it is difficult to replace. CONTENT OF THE UTILITY MODEL

[0017] The technical scheme of the utility model will be described clearly and completely in combination with the drawings and specific embodiments. As Figures 2-3As shown, a detachable support structure for fixing a wire harness 3 includes a long rod 2 fixedly mounted on a vehicle frame 1. The long rod 2 is detachably mounted on the vehicle frame 1, and at least two fixing structures for fixing the wire harness 3 and the long rod 2 are spaced apart on the long rod 2. The cross-sectional shape of the long rod 2 can be various, such as square or circular. The long rod 2 and the wire harness 3 are tied together for fixation, preventing the wire harness 3 from sagging due to gravity. The length of the long rod 2 can be set as needed. The material of the long rod 2 only needs to be resistant to bending and deformation under stress; for example, metals such as steel, iron, aluminum, and alloys, or non-metallic materials that are not easily deformed, are all acceptable. Existing long rods 2 are welded to the vehicle frame 1 by fixing at both ends or by setting multiple mounting seats 5 in the middle. The installation and disassembly process is cumbersome, and replacement is time-consuming and labor-intensive if damaged. There are various detachable connection methods, such as bolt connections and tight fits. In this utility model, the long rod 2 is fixed to the vehicle frame 1 by a detachable connection, which can be easily removed, satisfying the function of supporting the wire harness 3 while achieving convenient installation and disassembly. It facilitates on-site operation during later inspection and maintenance, and also makes it easy to replace and repair damaged parts.

[0018] Specifically, mounting seats 5 are spaced along the length of the frame 1, and wire clips are detachably mounted on the mounting seats 5. The long rod 2 passes through all the wire clips and is detachably fixedly connected to at least two of them. If the mounting seats 5 and the wire clips are integrally formed from the same bracket part, replacing the long rod 2 with a different size would require replacing the mounting seats 5. For structural stability, the mounting seats 5 are generally fixed to the frame 1 by welding or other methods, making replacement cumbersome. Therefore, in this invention, the mounting seats 5 and the wire clips are preferably detachably connected. Long rods 2 of different lengths and diameters can be selected according to the needs of different engineering vehicles. Since various models and sizes of wire clips are available on the market, simply replacing the wire clips with different models and sizes according to the dimensions of the long rod 2 will accommodate different sizes of long rods 2. The mounting seats 5 and the wire clips can use existing structures, which are easy to assemble and disassemble. Of course, the mounting seats 5 and the wire clips can also be omitted, and other commonly used fixing methods can be used to detachably connect the long rod 2.

[0019] Furthermore, the wire clamp includes an annular sleeve, and the long rod 2 has a circular cross-section. The long rod 2 and the annular sleeve of the wire clamp fit tightly together. This tight fit allows for detachable connection. Preferably, the long rod 2 fits tightly with the annular sleeves of all wire clamps, resulting in a more stable structure that prevents wobbling along its length or in other directions, thus avoiding detachment. The long rod 2 can be a round steel rod or a hollow round steel tube, or other common materials.

[0020] Furthermore, one end of the mounting base 5 is welded to the vehicle frame 1, and the mounting base 5 has a threaded hole; the wire clamp is a P-shaped wire clamp, one end of which is fitted onto the bolt, and the bolt and the threaded hole mate; after tightening the bolt, the wire clamp is fixed between the mounting base 5 and the head of the bolt. The model of the P-shaped wire clamp 6 is determined according to the outer diameter of the long rod 2, and it has an interference fit with the long rod 2. The mounting base 5 can be cylindrical, with a threaded hole inside the cylinder. One end of the cylinder is welded to the vehicle frame 1, and the other end of the cylinder presses against one end of the P-shaped wire clamp 6 between the bolt and the cylinder. A washer can also be placed between the bolt and the P-shaped wire clamp. One end of the P-shaped wire clamp 6 has a through hole for installation and fixing, and the other end has a ring. The structure of the P-shaped wire clamp 6 is prior art and will not be described in detail.

[0021] Preferably, the threaded hole on the mounting base 5 has a diameter of M8. This diameter threaded hole can be universally matched with other brackets or cable clip structures on the vehicle frame. This facilitates the subsequent expansion of the vehicle with the installation of other cable clips or other different types of brackets, providing greater flexibility.

[0022] Furthermore, the mounting bases 5 are welded onto the frame 1 at intervals of at least 1 meter. In existing structures, as shown in the attached diagram... Figure 1 In the existing structure shown, multiple short cable conduits 7 are welded along the length of the frame 1. The cable conduits 7 can be T-shaped, with one side welded to the frame 1 and the other side used to fix the wire harness 3. The wire harness 3 and the cable conduits 7 are fixed together with cable ties 4. This structure may require welding four cable conduits 7 per meter to prevent the wire harness 3 from sagging. In another existing structure, a bracket is fixed to the frame, and a wire clamp is mounted on the bracket, with the wire harness 3 positioned within the clamp. This structure may require ten mounting bases 5 per meter, otherwise the wire harness 3 will sag. In this invention, one mounting base 5 is welded every meter or longer to meet the fixing requirements of the long rod 2, preventing the wire harness 3 from sagging due to gravity. The structure of this invention significantly reduces the number of mounting bases 5 or brackets welded to the frame 1, greatly improving on-site welding efficiency.

[0023] Specifically, the fixing structure between the wire harness 3 and the long rod 2 is a cable tie 4 that together loops around and secures both. Using the cable tie 4 to fix the wire harness 3 and the long rod 2 is existing technology and will not be described in detail. The cable tie 4 comes in various models and sizes, which can be selected according to needs. Other common fixing structures can also be used. The fixing spacing of the cable tie 4 can be adjusted according to the requirements of the wire harness 3's arrangement, and the wire harness 3 is arranged horizontally and vertically following the direction of the long rod 2, improving the aesthetics of the wire harness 3; it also facilitates on-site personnel operation during later inspection and maintenance, and facilitates replacement and repair if components are damaged, greatly improving the convenience and efficiency of later inspection and maintenance.

[0024] During installation, the mounting bases 5 can be welded along the frame 1 at intervals of 1 meter or more. The long rod 2 is then fixedly fitted into the loops of several P-type wire clips 6, with each P-type wire clip spaced 1 meter apart. The P-type wire clips 6 and their corresponding mounting bases 5 are then secured with bolts. Later, when fixing the wire harness 3, the wire harness 3 and the long rod 2 are simply secured together with the cable ties 4.

[0025] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
