Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness technology, and more specifically, to a detachable multifunctional combination bracket. Background Technology

[0002] Heavy commercial vehicles operate in more complex environments than passenger cars, such as national highways, expressways, and mining areas. As production tools, their prolonged operation makes various components prone to failure. Generally, maintenance based on the condition of individual components ensures normal vehicle operation. However, the vehicle's wiring harness, as the sole transmission medium for electrical signals, is susceptible to wear and short circuits if improperly installed and secured. Problems with the wiring harness can lead to malfunctions in the vehicle's electrical components, causing the vehicle to malfunction and become unable to operate normally.

[0003] Currently, wiring harnesses in heavy commercial vehicles are typically secured using single-hole "L"-shaped brackets, double-hole or multi-hole bent brackets, or more complex bracket structures, or by bundling the wiring harness along with the conduit. Double-hole or multi-hole bent brackets and single-hole L-shaped brackets are generally made of metal, which is prone to rusting over time, affecting aesthetics and strength. Metal brackets are also relatively heavy, and a large number of them can increase the overall vehicle weight.

[0004] When securing wire harnesses, space constraints can make the process difficult. Using cable ties can be challenging, as cable tie guns are often ineffective and the ties are difficult to tighten, causing the harness to wobble and potentially leading to wear. Brackets may not provide adequate positioning, resulting in inconsistent wire lengths and inconsistent condition.

[0005] When using bolts to fix single-hole brackets, the bracket is prone to rotation, increasing the difficulty of fixing and wasting time. Fixing the wiring harness together with the conduit can easily cause wear on the harness, and it also makes maintenance less convenient, requiring more time and labor to replace the harness.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] according to Figures 1 to 4 As shown, the present invention provides a detachable multi-functional combination bracket, including a connecting plate 1 and a positioning mechanism;

[0032] The connecting plate 1 has a boss 2 on one side, and a groove 3 is provided in the boss 2; the connecting plate 1 has cable tie grooves 14 at both ends of the boss 2, and the cable tie grooves 14 are used to fix the connecting plate 1 to the pipeline by cable ties.

[0033] The positioning mechanism includes a positioning block 4 and a positioning rod 6. The positioning block 4 is embedded in the groove 3 and has a cavity 5. The side wall of the cavity 5 has an internal thread. One end of the positioning rod 6 is threaded to the cavity 5, and the other end extends toward the end away from the connecting plate 1 and is located outside the positioning block 4. The positioning rod 6 is inserted into the frame hole to position and fix the connecting plate 1 and the bundled pipeline.

[0034] In this embodiment, the connecting plate 1 mainly fixes the pipeline through the cable tie groove 14, and the external structure of the connecting plate 1 is not limited to the structure shown in the figure.

[0035] Furthermore, a positioning ring 8 is provided inside the cavity 5, and the positioning ring 8 is sleeved on the positioning rod 6; a spring 10 is provided between the threaded portion 7 of the positioning rod 6 and the positioning ring 8, and the spring 10 is sleeved on the positioning rod 6. A limiting plate 9 is provided at one end of the positioning ring 8 near the spring 10, and the end of the cavity 5 away from the connecting plate 1 contracts inward to abut against the limiting plate 9.

[0036] During implementation, the positioning rod 6 is threaded into the positioning block 4, and the spring 10 is limited by the threaded portion 7 of the positioning rod 6 and the limiting plate 9 of the positioning ring 8. The positioning ring 8 is also limited between the limiting plate 9 and the positioning block 4. When the positioning block 4 needs to be fixed to the frame hole, if the frame hole diameter is small, the positioning block 4 is aligned with the center of the frame hole by the positioning rod 6. Because the frame hole diameter is smaller than the positioning ring 8, when tightening with the nut, the positioning ring 8 is compressed into the positioning block 4. Simultaneously, the spring 10 applies a reverse force to the positioning ring 8 through its elasticity, pressing the positioning ring 8 tightly against the frame surface, making the fixing of the positioning block 4 more secure. When the frame hole diameter is large, the positioning block 4 is aligned with the center of the frame hole by the positioning ring 8.

[0037] Furthermore, the positioning block 4 has a cylindrical structure, and the groove 3 fits into the positioning block 4. An annular groove 11 is provided on the circumferential surface of the positioning block 4, and a retaining ring 12 is provided on the side wall of the groove 3 to engage with the annular groove 11, allowing the positioning block 4 and the boss 2 to rotate circumferentially. After the positioning block 4 is engaged in the groove 3 of the connecting plate 1, the connecting plate 1 can rotate 360 ​​degrees around the axis of the positioning block 4 to meet assembly requirements at different angles.

[0038] Furthermore, the sidewall of the boss 2 is provided with multiple axially arranged slots 13, and the slots 13 extend into the groove 3, with equal spacing between adjacent slots 13. In implementation, due to the presence of the slots 13, after the positioning block 4 is engaged in the connecting plate 1, each individual part can be pried up with a tool, thereby achieving detachability between the connecting plate 1 and the positioning block 4.

[0039] Furthermore, the circumferential surface of the positioning block 4 near the end of the connecting plate 1 is provided with a radially penetrating cable tie hole 15. When the connecting plate 1 and the positioning block 4 are detached, the positioning block 4 can use the cable tie hole 15 to secure the pipeline. The cable tie hole 15 in the positioning block 4 is a slot for cable ties; when the connecting plate 1 cannot be installed at a certain location inside the vehicle, the cable tie hole 15 in the positioning block 4 can be used to fix the pipeline.

[0040] Optionally, in the detachable multi-functional combination bracket according to the present invention, the cable tie hole 15 is provided with at least two holes, and the cable tie hole 15 passes through the axis of the positioning block 4.

[0041] The present invention can design the positioning block 4 and the positioning ring 8 to be of different sizes according to the actual installation position, so as to adapt to the installation of different hole diameters, and at the same time satisfy the centering function of bracket installation with different hole diameters.

[0042] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
