Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness assembly technology, specifically to an adaptively adjustable automotive wiring harness assembly. Background Technology

[0002] As the core network of automotive circuits, automotive wiring harnesses are crucial for ensuring the coordinated operation of various electronic and electrical components. Their performance directly affects the safe operation and reliability of automobiles. With the trend of intelligent and electric vehicles, the number of on-board electronic devices has increased significantly, the structure of wiring harness systems has become more complex, the number of branch lines has increased and the layout has become more dense, which puts forward higher requirements for their adaptability and stability.

[0003] Traditional automotive wiring harnesses, due to their fixed-length design, are highly susceptible to tension imbalances caused by factors such as vehicle vibration, temperature changes, and relative displacement of components during actual assembly and vehicle operation. When the tension is too high, the wiring harness insulation layer is easily worn, and the wires may break, leading to short circuits or signal transmission interruptions. Conversely, when the tension is too low, the wiring harness is prone to slack and droop, causing friction and interference with surrounding components, which also poses a serious safety risk.

[0004] A car wiring harness assembly with application number CN202422161527.4, although it achieves the winding and fixing of the wiring harness through a roll cover, effectively reduces the space occupied after winding and makes the installation operation more convenient compared with the fixing method using a limiting plate. However, due to the limitations of the complex structural environment inside the vehicle, the device is not equipped with a wiring harness tension adjustment structure. This causes the wiring harness to be prone to abnormal tension during vehicle operation due to external forces such as compression and pulling in the complex environment, which can lead to damage to the wiring harness and cause abnormal vehicle functions. It is difficult to meet the requirements of modern automobiles for the adaptive adjustment capability of the wiring harness.

[0005] Based on this, this solution proposes "an adaptively adjustable automotive wiring harness assembly" to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an adaptively adjustable automotive wiring harness assembly to solve the problem mentioned in the background art that existing market equipment does not have a wiring harness tension adjustment structure, which leads to abnormal tension of the wiring harness during vehicle operation due to external forces such as compression and pulling in complex environments, resulting in damage to the wiring harness.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adaptively adjustable automotive wiring harness assembly, comprising a first electrode, a second electrode, a fixing block, a protective sheath, and a limiting pin;

[0008] An adaptive adjustment function is provided on the side of the first electrode. The adaptive adjustment function includes a first sleeve, an electrostrictive polymer component, a second sleeve, a second clamp, a first clamp, and a third sleeve. The first sleeve is installed on the side of the second sleeve via the first clamp, and the second sleeve is installed on the side of the third sleeve via the second clamp. Electrostrictive polymer components are provided on the surfaces of the first sleeve, the second sleeve, and the third sleeve. The electrostrictive polymer component is a composite electrostrictive material formed by doping nano-conductive particles with polyvinylidene fluoride (PVDF) or its copolymer as the base material. It generates expansion and contraction strain under the action of an electric field and expands and contracts after being energized, which is used to control the length and tension of the branch wire harness.

[0009] As a preferred embodiment of the present invention, the first electrode is fixedly connected to the fixing block, and the second electrode is fixedly connected to the side of the fixing block, wherein the second electrode has the same structure as the first electrode;

[0010] Using the above technical solution, the protective sheaths on the surfaces of the second electrode and the first electrode employ a double-layer structure of inner silicone rubber and outer polyurethane, achieving functional complementarity. The inner flexible silicone rubber possesses excellent insulation and elasticity, allowing it to tightly adhere to the electrode surface and buffer the impact of external vibrations; the outer high-strength polyurethane significantly improves the electrode's wear resistance, aging resistance, and corrosion resistance, resisting the erosion of oil, dust, and other contaminants in the automotive operating environment, effectively extending the electrode's service life and ensuring the safety of the wiring harness's electrical connections.

[0011] As a preferred embodiment of the present invention, both the second electrode and the first electrode are covered with a protective sheath. The protective sheath includes an inner layer and an outer layer. The inner layer of the protective sheath is a flexible silicone rubber layer, and the outer layer of the protective sheath is a high-strength polyurethane layer.

[0012] Using the above technical solution, the diamond-shaped fixing block has higher structural stability within the same installation space. The four evenly distributed bolt holes allow for multi-angle fixing, enhancing the firmness of the connection between the wiring harness assembly and the vehicle body and reducing the risk of loosening caused by vehicle vibration. The fixed connection between the fixing block and the cable body, as well as the protective sheath on the surface of the cable body, further strengthens the structural strength and protection of the connection area, preventing damage caused by stress concentration.

[0013] As a preferred technical solution of the present invention, the fixing block is generally rhomboid in shape, and bolt holes are opened on the side of the fixing block. There are four bolt holes evenly distributed. The fixing block on the same side of the bolt holes is fixedly connected to the cable body, and the surface of the cable body is covered with a protective sheath.

[0014] Using the above technical solution, the first, second, and third sleeves on the outer side of the cable body are connected in series via a second clamp and a first clamp, achieving modular assembly. This facilitates rapid installation and subsequent maintenance and replacement, reducing operational difficulty. The sleeve design with the same structure improves the versatility of components, reduces the types of molds, and saves costs. Furthermore, the displacement and tension sensors configured in the branch harness can monitor the harness status in real time, providing precise data for adjusting the electrostrictive polymer components, ensuring timely and accurate adjustments.

[0015] As a preferred technical solution of the present invention, the outer side of the cable body is sequentially covered with a first sleeve, a second sleeve, and a third sleeve. The first sleeve, the second sleeve, and the third sleeve are connected in series by a second clamp and a first clamp. The first sleeve, the second sleeve, and the third sleeve all adopt the same structure, and the branch wire harness inside the cable body is equipped with a displacement sensor and a tension sensor.

[0016] By adopting the above technical solution, the second structural ring on the left side of the first sleeve is rotatably connected to the connecting rod and the first structural ring, forming a flexible linkage structure. When the electrostrictive polymer assembly extends or retracts, the connecting rod can rotate with the structural ring to assist the sleeve in making fine adjustments to its angle and position, avoiding stress concentration caused by rigid connection between sleeves, reducing mechanical wear of sleeves and wire harnesses, and improving the flexibility and service life of the overall structure.

[0017] As a preferred technical solution of the present invention, the second structural ring on the left side of the first sleeve is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the first structural ring, and the first structural ring and the second structural ring have the same structure and face each other.

[0018] Using the above technical solution, a fixed electrostrictive polymer component is sandwiched between the first sleeve and the second structural ring, ensuring its stable installation and preventing displacement or detachment during expansion and contraction. The corrugated section on the side can adapt to the deformation of the electrostrictive polymer component, further buffering the tension on the wire harness; the flexible conductive film on the inner side ensures uniform current distribution, guaranteeing the stability and consistency of the expansion and contraction performance of the electrostrictive polymer component and improving adjustment accuracy.

[0019] As a preferred embodiment of the present invention, an electrostrictive polymer assembly is sandwiched between the first sleeve and the second structural ring, the side of the electrostrictive polymer assembly is fixedly connected to the corrugated pipe portion, and a flexible conductive film is disposed on the inner side of the electrostrictive polymer assembly.

[0020] By adopting the above technical solution, the matching design of the protrusion of the first clamp and the groove on the surface of the first structural ring achieves precise positioning and tight connection between the pipe sleeves, preventing relative rotation or axial displacement of the pipe sleeves during vehicle operation. The combination of pins and bolts for fixing not only ensures the locking force of the clamp but also facilitates quick disassembly and installation, improving the reliability of the pipe sleeve connection and the convenience of maintenance.

[0021] As a preferred technical solution of the present invention, a first clamp is fitted on the right side of the first structural ring of the first sleeve, and a protrusion is fixedly connected to the inner wall of the first clamp. A groove matching the protrusion of the first clamp is provided on the surface of the first structural ring. A second structural ring of the second sleeve is fitted on the other side of the first clamp. A pair of pins are fixedly connected to one side of the first clamp, and a bolt is threaded to the other side of the first clamp.

[0022] By adopting the above technical solution, the fixed connection between the first connecting block and the cable body ensures the structural stability of the wiring part, and the evenly spaced wiring holes facilitate the orderly connection of branch wire harnesses, avoiding wire chaos. The cooperation between the fixing plate, the first clamp, the second clamp, and the spring allows the clamp to tightly clamp the connection part, preventing the wire harness from loosening during vibration. The elasticity of the spring can also buffer the stress at the connection part, protect the wire harness interface, and improve the connection reliability.

[0023] As a preferred technical solution of the present invention, the cable body is fixedly connected to the first connecting block, the first connecting block has evenly spaced wiring holes on its right side, and a fixing plate is fixedly connected to the side of the first connecting block. The upper part of the fixing plate is rotatably connected to the first clamping claw, and the lower part of the fixing plate is rotatably connected to the second clamping claw. Springs are fixedly connected between the fixing plate and the first and second clamping claws, and the first and second clamping claws have the same overall structure. The hinge joint of the first and second clamping claws is spliced ​​into a ring structure.

[0024] The first connecting block is slidably connected to the second connecting block on its right side, and the second connecting block is fixedly connected to a terminal post on its left side. The terminal post is adapted to the wiring hole of the first connecting block, and limiting pins are fixedly connected to both sides of the wiring hole.

[0025] The sliding connection design of the first and second connecting blocks, using the above technical solution, facilitates precise alignment of the terminals and wiring holes, reducing the difficulty of installation and alignment. The matching of the terminals and wiring holes ensures the stability of the electrical connection, while the limiting pin prevents misalignment during alignment, ensuring connection accuracy, reducing poor contact problems, and improving the reliability of the connection between the wiring harness assembly and automotive components.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The connection between the electrode and the fixing plate and the symmetrical structural design ensure the stability and performance consistency of the electrode installation. The standardized structure facilitates production and processing, and also provides a unified benchmark for subsequent cooperation, thereby improving the reliability of the overall electrical connection.

[0028] The protective structure design has significant advantages. The protective sheath on the surface of the electrodes and cables adopts a double-layer structure of inner silicone rubber and outer polyurethane. The insulation and elasticity of the inner silicone rubber can buffer the impact, while the outer polyurethane enhances the wear resistance, aging resistance and corrosion resistance, which can resist the erosion of the complex automotive environment and effectively extend the service life of the components.

[0029] The structural design of the fixing plate and the sleeve is reasonable. The diamond-shaped fixing plate and the evenly distributed bolt holes improve the firmness of the connection with the vehicle body and reduce vibration and loosening. The sleeves are connected in series by clamps to achieve modular assembly. The sleeves with the same structure are conducive to universality, reducing production and maintenance costs. The configuration of displacement and tension sensors provides accurate data support for adaptive adjustment.

[0030] The linkage and adjustment structure is ingeniously designed. The rotational connection between the connecting rod and the structural ring forms a flexible linkage, avoiding stress concentration caused by the rigid connection of the sleeve. The fixing method of the electrostrictive polymer component and the matching bellows and flexible conductive film ensure the stability and accuracy of the telescopic adjustment, and improve the flexibility and durability of the overall structure.

[0031] The connection parts are reliably designed. The convex and groove of the clamp and the pin bolt fixation ensure that the pipe sleeve connection is accurate, stable and easy to disassemble and assemble. The sliding connection of the connecting block, the matching of the terminal and the terminal hole and the limit pin design reduce the installation difficulty and ensure the accuracy and stability of the connection. The cooperation between the claw and the spring further improves the reliability of the connection parts and reduces the problem of poor contact. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 - Figure 10 The technical solution of this invention is as follows: an adaptively adjustable automotive wiring harness assembly, comprising a first electrode 1, a second electrode 2, a fixing block 3, a protective sheath 301, a bolt hole 302, a cable body 303, a first sleeve 4, an electrostrictive polymer assembly 401, a first structural ring 402, a second structural ring 403, a connecting rod 404, a second sleeve 5, a second clamp 6, a first clamp 7, a protrusion 701, a bolt 702, a pin 703, a third sleeve 8, a first connecting block 9, a wiring hole 901, a first gripper 902, a second gripper 903, a fixing plate 904, a spring 905, a second connecting block 10, a terminal post 101, and a limiting pin 102;

[0045] The electrostrictive polymer assembly 401 drive system integrated on the side of the first electrode 1 is a major highlight. The first sleeve 4, the second sleeve 5, and the third sleeve 8 adopt a modular series design, which, together with the first clamp 7 and the second clamp 6, enables rapid assembly. This not only meets the needs of cost reduction and efficiency improvement in the automotive manufacturing industry, but also facilitates the upgrading and after-sales maintenance of the wiring harness assembly. The electrostrictive polymer assembly 401 is not a single polymer material body. It is a composite electrostrictive material formed by doping nano-conductive particles with polyvinylidene fluoride (PVDF) or its copolymer as the base material. It is an integrated assembly with a matching fixing structure, a corrugated tube part, and a flexible conductive film. Based on the inverse piezoelectric effect, it can produce controllable expansion and contraction deformation under the action of an electric field. With the help of displacement sensors and tension sensors, a closed-loop control system is formed, which can adjust the wiring harness tension in real time according to the vehicle's operating conditions to avoid loosening or breakage due to vibration.

[0046] The electrode protection system adopts a composite structure. The protective sheath 301 on the surface of the first electrode 1 and the second electrode 2 includes an inner layer and an outer layer. The inner layer of flexible silicone rubber has excellent insulation and elasticity, and can maintain stable performance in extreme temperature environments. It fits tightly against the electrode surface and buffers external vibration and impact. The outer layer of high-strength polyurethane is enhanced with a special formula to improve wear resistance, aging resistance and corrosion resistance. It can effectively resist various types of erosion in the automotive operating environment. This double-layer structure has been verified by finite element analysis, which can significantly reduce stress concentration on the electrode surface and greatly extend the service life of the electrodes.

[0047] The fixing block 3 adopts a rhomboid topology optimization structure. Compared with the traditional rectangular structure, the torsional stiffness is significantly improved with the same amount of material. The four evenly distributed bolt holes 302, together with the anti-loosening nut and elastic washer, enhance the firmness of the connection between the wiring harness assembly and the vehicle body, and reduce the risk of loosening caused by vehicle vibration. The protective sheath 301 of the connection part of the cable body 303 forms an integrated protection with the fixing block 3. It has been verified by tensile fatigue test that it can withstand a large number of cyclic loads without failure.

[0048] The tube sleeve connection mechanism achieves synergistic optimization in mechanical and electrical performance. The matching design of the protrusion 701 of the first clamp 7 and the groove on the surface of the first structural ring 402 of the first tube sleeve 4 ensures precise docking of the tube sleeve. Combined with the dual fastening method of the pin 703 and the bolt 702, it ensures a stable connection. The flexible conductive film configured on the inner side of the electrostrictive polymer component 401 has good conductivity stability, which can ensure a fast response of the drive system even in the state of expansion and contraction deformation.

[0049] The wiring module adopts a quick-connect design. The cable body 303 is fixedly connected to the first connecting block 9. Wiring holes 901 are evenly opened on the right side of the first connecting block 9. The sliding guide mechanism of the first connecting block 9 and the second connecting block 10 makes it easier to connect the terminal 101 and the wiring hole 901, improving assembly efficiency. The terminal 101 and the wiring hole 901 use gold-plated contacts. The anti-mistake design of the limit pin 102 avoids poor contact caused by assembly errors. The clamping mechanism composed of the fixing plate 904 on the side of the first connecting block 9, the first clamp 902, the second clamp 903 and the spring 905 can stably clamp the connection parts under different temperature environments through the constant force spring 905, effectively suppressing fretting wear.

[0050] Working principle: When using an adaptive adjustable automotive wiring harness assembly, the entire wiring harness assembly is first fixed to the designated position on the vehicle body using bolts 702 through four evenly distributed bolt holes 302 on the fixing block 3, ensuring the overall stability of the installation. At this time, the first electrode 1 and the second electrode 2 form a symmetrical electrical connection structure through the fixing block 3. The inner layer of the protective sheath 301 covering its surface is tightly attached to the electrode with silicone rubber, and the outer layer of polyurethane resists external environmental corrosion, ensuring the stability of the electrode's initial working state.

[0051] When the vehicle is in operation, the relative positions of the body parts change due to vibration, bumps, etc. The displacement sensor and tension sensor configured in the branch harness inside the cable body 303 will detect the changes in the length and tension fluctuations of the branch harness in real time and transmit these signals to the vehicle control system. The control system analyzes and processes the signals according to the preset algorithm, and then sends electrical signals to the flexible conductive film inside the electrostrictive polymer assembly 401 on the surface of the first sleeve 4, the second sleeve 5, and the third sleeve 8.

[0052] After receiving an electrical signal, the electrostrictive polymer assembly 401 will undergo corresponding expansion and contraction deformation according to the voltage magnitude. Its expansion and contraction will drive the first structural ring 402 and the second structural ring 403, which are clamped and fixed to it, to move. The two ends of the connecting rod 404 are rotatably connected to the first structural ring 402 and the second structural ring 403 respectively, playing a flexible linkage role during the movement of the structural rings, avoiding stress concentration caused by rigid connection between the sleeves. At the same time, the corrugated part on the side of the electrostrictive polymer assembly 401 will adapt to its expansion and contraction to further buffer the tension on the wire harness, ensuring that the length and tension of the branch wire harness are always within a reasonable range.

[0053] During the expansion and contraction adjustment of the sleeve, the first clamp 7 and the second clamp 6, through the matching design of the protrusion 701 and the groove on the surface of the structural ring, ensure the accuracy and stability of the connection between the first sleeve 4, the second sleeve 5, and the third sleeve 8, and prevent relative displacement from affecting the adjustment effect. When it is necessary to connect to other automotive parts, the terminal 101 on the left side of the second connecting block 10 is aligned with the wiring hole 901 of the first connecting block 9. The sliding cooperation between the first connecting block 9 and the second connecting block 10 achieves precise connection. The limiting pins 102 on both sides of the wiring hole 901 ensure that there is no offset during connection. At this time, the first jaw 902 and the second jaw 903 form a ring structure clamping connection under the elastic force of the spring 905, ensuring the reliability of the electrical connection.

[0054] If maintenance or replacement of the sleeve is required in the future, simply loosen the bolts 702 on the first clamp 7 and the second clamp 6 to disengage the pin 703, and the sleeve can be easily removed. The operation is simple and efficient. During the entire operation, the components work together to achieve the adaptive adjustment function of the wiring harness assembly through real-time monitoring, intelligent adjustment and stable connection, so as to ensure the continuous and stable operation of the automotive circuit.

[0055] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
