Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a multifunctional integrated automotive wheel wiring harness. Background Technology

[0002] With the increasing electrification and intelligence of automobiles, more and more electronic functions are being added to wheel system accessories. Compared to the single wheel speed or electronic parking brake functions of previous vehicles, current vehicles have added functions such as height sensors, electromagnetic dampers, acceleration sensors, and friction plate sensors to the original wheel harnesses. How to arrange wheel harnesses with multiple functions in the limited space of the wheel system has become an important issue for OEMs. At the same time, as the signal bridge for wheel speed and braking, the wheel harness is closely related to the overall vehicle safety performance. Excellent design can ensure that the wheel harness can withstand millions of bending tests, thereby avoiding the occurrence of accidents involving people and vehicles.

[0003] The original single-function wheel harness design no longer meets the needs of a multi-functional wheel harness, which is reflected in the following aspects:

[0004] 1. The original single-function wheel harness is integrated with the wheel speed or electronic handbrake motor on the wheel hub, which can only meet the needs of a single function. Moreover, when replacing the wheel harness after the sale, the entire module needs to be replaced, which results in high unit cost and difficult after-sales maintenance.

[0005] 2. Multifunctional wheel harnesses solve the problem of arranging multiple functional wheel harnesses within the motion envelope of a moving wheel system structure. Wheel harness design typically considers tire steering and vertical movement. Under different motion conditions, the wheel harness needs to ensure it does not interfere with the movement of related structural components in the wheel system. Therefore, the space available for arranging wheel harnesses is very limited. Currently, the arrangement of the moving sections of the wheel harness is basically aligned with the brake hoses along both sides of the wheel axle center. With the requirements of multifunctional wheel harnesses, if each function is arranged separately, different functional wheel harnesses will inevitably interfere with and wear on surrounding components and other wheel harnesses, leading to functional failure.

[0006] The patent with announcement number "CN 216886564 U" discloses an "integrated automotive electronic parking brake wiring harness and vehicle". Although it achieves the integration and arrangement of the electronic parking brake wiring harness, it only integrates two functions, which is a small number of functions. In addition, the rubber gasket used to connect the wiring harness is a pre-made product, which needs to be installed on the wiring harness later, resulting in unreliable connection. Utility Model Content

[0007] The purpose of this utility model is to provide a multi-functional integrated automotive wheel harness that achieves all-round protection and fixation of the multi-functional wheel harness.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A multifunctional integrated automotive wheel wiring harness has a moving section, one end of which is connected to a main wiring harness section, and the other end of which is connected to at least two branch wiring harness sections via an integrated connector, wherein the integrated connector is injection molded on the moving section and the branch wiring harness sections.

[0010] Preferably, both the main harness segment and the branch harness segment have a mating joint at their ends furthest from the moving segment, and the mating joint is injection molded onto the main harness segment or the branch harness segment.

[0011] Preferably, a wire harness fixing clip is installed on the main wire harness segment and / or the branch wire harness segment.

[0012] Preferably, the vehicle wheel wiring harness includes a front wheel wiring harness and a rear wheel wiring harness;

[0013] The front wheel wiring harness includes a front wheel moving section. One end of the front wheel moving section is connected to the front wheel main wiring harness section and the front wheel first branch wiring harness section through a front wheel first integrated connector. The other end of the front wheel moving section is connected to the front wheel second branch wiring harness section and the front wheel third branch wiring harness section through a front wheel second integrated connector. The front wheel third branch wiring harness section is connected to the front wheel fourth branch wiring harness section through a front wheel third integrated connector.

[0014] Preferably, the end of the front wheel main harness segment is connected to the front wheel main harness via a front wheel first docking connector, the end of the front wheel first branch harness segment is connected to a height sensor via a front wheel second docking connector, the end of the front wheel second branch harness segment is connected to the front wheel electromagnetic shock absorber via a front wheel third docking connector, the end of the front wheel fourth branch harness segment is connected to the front wheel wheel speed sensor via a front wheel fourth docking connector, and the front wheel third integrated connector is also connected to the front wheel friction plate sensor via a front wheel fifth docking connector.

[0015] Preferably, the rear wheel wiring harness includes a rear wheel main wiring harness segment, on which a first rear wheel fixed connector and a second rear wheel fixed connector are respectively provided. The rear wheel main wiring harness segment between the first rear wheel fixed connector and the second rear wheel fixed connector forms a rear wheel moving segment. One end of the rear wheel main wiring harness segment is connected to the rear wheel main wiring harness through a first rear wheel mating connector, and the other end of the rear wheel main wiring harness segment is connected to a first rear wheel branch wiring harness segment and a second rear wheel branch wiring harness segment through a rear wheel integrated connector.

[0016] Preferably, the end of the first branch harness segment of the rear wheel is connected to the rear wheel speed sensor through the second rear wheel docking joint, the end of the second branch harness segment of the rear wheel is connected to the rear wheel electromagnetic shock absorber through the third rear wheel docking joint, and the rear wheel integrated joint is also connected to the electronic handbrake caliper through the fourth rear wheel docking joint.

[0017] Preferably, a third fixed connector for the rear wheel is provided in the middle of the second branch harness segment of the rear wheel, and a fourth fixed connector for the rear wheel is provided on the main harness segment of the rear wheel, with the fourth fixed connector located between the first fixed connector and the first mating connector of the rear wheel.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This allows multiple functional harnesses to share a single motion segment, thus avoiding the problem of insufficient space when multiple motion wheel harnesses are arranged together. It also solves the problem of branch point wiring when multiple functional harnesses share a single motion segment: the branch point is combined with the fixed point and the plug tail by injection-molded integrated connector, which reduces the space required for branch point arrangement and restricts the wiring direction, avoiding the problem that the wiring direction of ordinary branches cannot be restricted.

[0020] 2. This significantly reduces the space occupied by multiple wheel harnesses in the limited wheel system and avoids interference between different functional movement segments. Furthermore, the injection molding design for the branches prevents water and gravel ingress and abrasion of the wire sheath at the tire area due to improper branching, ensuring excellent sealing performance of the wheel harness branches. Integrating multiple functional harnesses also greatly reduces overall costs, enhancing the OEM's competitiveness in this area.

[0021] 3. Connectors for connecting to the wiring harness on the vehicle body are provided at the ends of the wiring harness, so that the wiring harness on the vehicle body can be plugged into the connectors of this application through standard plugs, which greatly reduces the unit cost and the difficulty of assembly and disassembly.

[0022] 4. This wiring harness also achieves high and low configuration compatibility for the same vehicle model and platformization issues between different vehicle models: Existing vehicle models all have high and low configurations, but the body sheet metal and wheel system related fixing points are the same. In the early design stage, this wiring harness designed fixing points and branch points in the form of high configuration, and solved the compatibility problem between low configuration single function and high configuration function by using different injection channels on the injection mold. It can meet the platformization requirements of different functions in different vehicle models, reduce the platformization requirements of multiple single function wheel wiring harnesses, and avoid the need for multiple development of multiple wheel wiring harnesses.

[0026] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0027] The present invention will now be further described with reference to the accompanying drawings. Example

[0028] like Figure 1 — Figure 3 As shown, a multifunctional integrated automotive wheel wiring harness includes a moving section. One end of the moving section connects to a main wiring harness segment, and the other end connects to at least two branch wiring harness segments via an integrated connector. The integrated connector is injection molded onto the moving section and the branch wiring harness segments. By using the moving section, when the aforementioned at least two branch wiring harness segments are in operation, only the moving section moves, while other parts remain stationary, avoiding potential interference between the wiring harnesses. The integrated connector in this application is injection molded. During the assembly of the automotive wheel wiring harness, the wiring harness segments are first connected, then the connection is placed in a mold, liquid injection molding compound is injected into the mold, and after cooling and solidification, an integrated connector integrally connected to the wiring harness segments is formed. The injection-molded integrated connector reduces the space required for branch point arrangement and restricts the outgoing wire direction, avoiding the problem of unrestricted outgoing wire direction in ordinary branch wiring harnesses.

[0029] Both the main harness segment and the branch harness segment have mating connectors at their ends furthest from the moving section. These mating connectors are injection molded onto the main harness segment or the branch harness segment. The injection molding of these connectors at the end of the harness facilitates connection with the harness on the vehicle body, significantly reducing unit cost and assembly / disassembly difficulty.

[0030] The main harness section and branch harness sections are equipped with harness fixing clips 17. The harness can be installed on the vehicle body using the harness fixing clips 17. Except for the moving sections, other parts of the harness will not shake, improving its reliability during use.

[0031] In this embodiment, the vehicle wheel wiring harness includes a front wheel wiring harness 100 and a rear wheel wiring harness 200;

[0032] like Figure 1 As shown, the front wheel wiring harness 100 includes a front wheel moving section 11. One end of the front wheel moving section 11 is connected to the front wheel main wiring harness section 12 and the front wheel first branch wiring harness section 13 through the front wheel first integrated connector 101. The other end of the front wheel moving section 11 is connected to the front wheel second branch wiring harness section 14 and the front wheel third branch wiring harness section 15 through the front wheel second integrated connector 102. The front wheel third branch wiring harness section 15 is connected to the front wheel fourth branch wiring harness section 16 through the front wheel third integrated connector 103.

[0033] The front wheel first integrated connector 101 is used for the integration of single-function branch wiring at the vehicle body end. The front wheel first integrated connector 101 is a T-shaped connector formed by injection molding, allowing the connected wire harnesses to exit in a fixed direction. The T-shaped connector is manufactured using an injection mold. After the wire harness is placed in the mold, TPU (tungsten polyurethane) of the same material as the outer layer of the wires is injected. The mold is then formed after injection molding, pressure holding, and cooling within the mold cavity. This structure takes into account the outer diameter of the main wire harness segment, branch wire harness segment, and moving segment, ensuring that the injection molded body completely encapsulates the wires. A mesh structure is also added at the connection end between the connector and the moving segment to alleviate stress during movement. The moving segment and functional branches exit according to the designed direction, avoiding interference with surrounding and relatively moving parts. This T-shaped connector innovatively combines sheet metal fixing points with wire harness branch points, reducing the complexity of mold development and processes. The front wheel moving segment 11 integrates multiple functional circuit branches at the tire end through the same wire harness segment, avoiding multiple functional branches and multiple moving segments, thereby reducing the need for multiple moving segments.

[0034] The front wheel second integrated connector 102 is used for the integration of multi-functional branch lines at the motion end. Compared to the branch points on the vehicle body, the wheel end often has multiple functional devices, which are irregularly distributed in space and require wiring harnesses to connect and avoid interference with surrounding components. Here, the front wheel second integrated connector 102 is designed as an H-shaped structure through injection molding, realizing the integration of one motion segment and two functional branches, and routing each functional branch according to the designed direction to avoid interference with surrounding components.

[0035] The end of the front wheel main harness segment 12 is connected to the front wheel main harness on the vehicle body through the front wheel first docking joint 111. The end of the front wheel first branch harness segment 13 is connected to the height sensor through the front wheel second docking joint 112. The end of the front wheel second branch harness segment 14 is connected to the front wheel electromagnetic shock absorber through the front wheel third docking joint 113. The end of the front wheel fourth branch harness segment 16 is connected to the front wheel wheel speed sensor through the front wheel fourth docking joint 114. The front wheel third integrated joint 103 is also connected to the front wheel friction plate sensor through the front wheel fifth docking joint 115.

[0036] The front wheel third integrated connector 103 is used for the branch line integration of the electrical terminal plug tail. The front wheel third integrated connector 103 is a T-shaped structure formed by injection molding. Because the outer wheel speed of the function at this location needs to be wired, and there is no space to arrange the new fixed point, the T-shaped front wheel third integrated connector 103 is used to combine the branch point, fixed point and plug tail, thereby realizing the wiring requirements of the outer functional branch.

[0037] The second front wheel connector 112 is used for injection molding of the tail of the straight-out wire plug. The second front wheel connector 112 is injection molded. The wire harness plug and the outer protective layer of the wire are injection molded along the natural wire exit direction of the plug through the injection mold. A mesh structure is designed at the tail of the injection molded structure to avoid stress on the plug and at the same time improve the waterproof and dustproof capabilities of the plug tail.

[0038] The third docking connector 113 of the front wheel is used for the tail treatment of the fixed direction plug-in. The third docking connector 113 of the front wheel is injection molded. Here, the plug-in needs to exit along the direction perpendicular to the tail of the plug-in. By designing an L-shaped structure at the tail of the plug-in, the functional branches are exited according to the overall design scheme, which ensures that there is no interference with the surrounding parts and at the same time reduces the length of the wire harness.

[0039] like Figure 2 and Figure 3 As shown, the rear wheel wiring harness 200 includes a rear wheel main wiring harness segment 22. A rear wheel first fixed connector 201 and a rear wheel second fixed connector 202 are respectively provided on the rear wheel main wiring harness segment 22. The rear wheel main wiring harness segment 22 between the rear wheel first fixed connector 201 and the rear wheel second fixed connector 202 forms a rear wheel moving segment 21. One end of the rear wheel main wiring harness segment 22 is connected to the rear wheel main wiring harness through a rear wheel first mating connector 211. The other end of the rear wheel main wiring harness segment 22 is connected to the rear wheel first branch wiring harness segment 23 and the rear wheel second branch wiring harness segment 24 through a rear wheel integrated connector 205.

[0040] The end of the first branch harness segment 23 of the rear wheel is connected to the rear wheel speed sensor through the second docking connector 212 of the rear wheel, the end of the second branch harness segment 24 of the rear wheel is connected to the rear wheel electromagnetic shock absorber through the third docking connector 213 of the rear wheel, and the rear wheel integrated connector 205 is also connected to the electronic handbrake caliper through the fourth docking connector 214 of the rear wheel.

[0041] The rear wheel second branch harness segment 24 is provided with a rear wheel third fixed connector 203 in the middle, and the rear wheel main harness segment 22 is provided with a rear wheel fourth fixed connector 204. The rear wheel fourth fixed connector 204 is located between the rear wheel first fixed connector 201 and the rear wheel first mating connector 211.

[0042] The rear wheel wiring harness 200 can be smoothly fixed to the vehicle body via the first rear wheel fixing connector 201, the second rear wheel fixing connector 202, and the third rear wheel fixing connector 203, without affecting the movement of the rear wheel moving section 21, and also preventing other parts of the wiring harness from shaking. The fourth rear wheel fixing connector 204 is a body-penetrating rubber sleeve for the rear wheel wiring harness to pass through the vehicle body.

[0043] The differences between the rear wheel wiring harness 200's first rear wheel fixing connector 201, second rear wheel fixing connector 202, and third rear wheel fixing connector 203 and the front wheel wiring harness 100's wiring harness fixing clip 17 are: 1. The two have different compatible wire diameters; 2. The rear wheel first fixing connector 201, second rear wheel fixing connector 202, and third rear wheel fixing connector 203 do not have a stress-relieving buffer structure (mainly because during normal vehicle operation, the front wheel wiring harness 100 may shake, while the rear wheel wiring harness 200 will not shake).

[0044] The rear wheel integrated connector 205 in the rear wheel wiring harness 200 is a branch point that shares an injection point with the plug-in. This connector design reduces the costs associated with injection mold development, fixing point development, or bracket development.

[0045] In addition, the specific structure of the rear wheel second docking joint 212 and the rear wheel third docking joint 213 in the rear wheel wiring harness 200, and the wiring harnesses they dock with, are the same as the structure of the front wheel third docking joint 113 and the front wheel fourth docking joint 114, respectively. This embodiment will not describe them in detail.

[0046] During assembly and use, this wiring harness primarily addresses the following issues through the integrated design of its moving sections:

[0047] 1. Multifunctional motion segment integration: Multiple circuits are integrated into a single conduit using sleeves or sheathed cables, reducing the number of multiple functional motion segments. This avoids the difficulty of arranging multiple functional motion segments within the wheel system's motion space.

[0048] 2. Branch points and fixed points share a single injection point. Multifunctional harnesses need to handle multiple functions and branching issues with the main harness. To minimize the number of fixed and branch points and reduce injection mold development, this innovative design combines branch points and fixed points into a single structure, while also reducing the development of additional components for mounting points.

[0049] 3. Branch point and plug-in share injection point treatment. This invention combines the injection molding of the multi-functional wire harness branch point and the plug-in tail, reducing the cost of injection mold development, fixing point or bracket development.

[0050] 4. Injection molding treatment at the tail of the plug-in to fix the cable exit direction. Injection molding at the tail of the plug-in solves the cable exit direction requirement for some plug-ins, while also improving the plug-in's waterproof and dustproof capabilities.

[0051] 5. The multi-functional wiring harness solves the problems of arranging and integrating multiple single-function wheel wiring harnesses and handling branch points, and also solves the platformization problem for high and low configuration models, meeting the functional requirements of adding wheel wiring harnesses to the whole vehicle.
