Description

Technical Field

[0001] This application relates to the technical field of wire harness installation auxiliary equipment, and in particular to a bendable bracket for wire harness support. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. They run through various parts of the vehicle and are the "neural network" of the automotive electrical system. Their application covers all types of vehicles, including traditional fuel vehicles, hybrid vehicles, and pure electric vehicles.

[0003] However, automotive wiring harnesses are typically installed directly inside the vehicle. These harnesses are prone to shaking during vehicle operation. Over time, this shaking can cause them to rub against other components inside the vehicle, leading to harness damage, wire breakage, and other issues that negatively impact the safety of the vehicle's electrical system. Summary of the Invention

[0004] To reduce the shaking of the wiring harness during vehicle operation, prevent the wiring harness from being damaged or broken due to friction with other components, ensure the safety of the vehicle's electrical system, and adapt to the complex wiring environment inside the vehicle, this application provides a bendable bracket for wiring harness support.

[0005] This application provides a bendable bracket for wire harness support, which adopts the following technical solution: A bendable bracket for supporting wire harnesses includes a bracket body with a placement groove for placing the wire harness. The bracket body is integrally injection molded according to the routing direction of the wire harness inside the vehicle. A bending portion is rotatably provided at the end of the bracket body, and the connection end of the wire harness to the vehicle is placed on the bending portion. The bracket body is provided with a first fixing mechanism and a second fixing mechanism. The first fixing mechanism is used to fix the bracket body to the vehicle, and the second fixing mechanism is used to fix the wire harness in the placement groove.

[0006] By adopting the above technical solution, the bracket body is securely installed on the vehicle by the first fixing mechanism, and the wire harness is placed in the placement slot and fixed by the second fixing mechanism, which effectively limits the shaking of the wire harness. At the same time, the bending part at the end of the bracket body can be rotated to adjust the angle, which can adapt to different wiring directions inside the vehicle, reduce the stress caused by forced bending of the wire harness, and further reduce the risk of wire harness damage.

[0007] Optionally, the bending portion includes: The first bending piece is a soft plastic sheet made of thermoplastic polyurethane elastomer material, and the first bending piece is disposed at the end of the bracket body; The mounting base plate is disposed on the end of the first bent piece away from the bracket body. The mounting base plate has a mounting groove for placing the end of the wire harness. The end of the mounting base plate away from the first bent piece has a connecting hole. The connecting hole passes through the inside and outside of the mounting base plate, and the wire harness passes through the connecting hole to connect with the vehicle. The third fixing mechanism is disposed on the mounting base plate and is used to fix the wire harness in the mounting groove.

[0008] By adopting the above technical solution, the first bending piece is made of thermoplastic polyurethane elastomer material, which has both good flexibility and toughness, can be bent at multiple angles and is not easy to break, ensuring the adjustment flexibility and service life of the bending part; the end of the wire harness is placed in the mounting groove and fixed by the third fixing mechanism, and the connecting end passes through the connecting hole to connect with the vehicle, making the installation of the end of the wire harness more stable and preventing the wire harness connecting end from loosening or falling off during vehicle operation.

[0009] Optionally, the first fixing mechanism includes: A first fixing plate is disposed on the outer wall of the bracket body, and a first fixing hole is provided on the first fixing plate for the bolts on the vehicle to pass through. A fixing ring is provided on the outer side wall of the bracket body, and an internal thread is provided on the inner side wall of the fixing ring.

[0010] By adopting the above technical solution, the first fixing mechanism provides two fixing methods: one is to fix the first fixing plate to the vehicle by passing bolts through the first fixing hole, which has strong connection stability and is suitable for positions where the fixing strength of the bracket is required; the other is to connect the fixing ring to the threaded post on the vehicle through the internal thread, which makes installation and disassembly more convenient and is suitable for scenarios that require frequent maintenance or adjustment of the bracket position. The two fixing methods can be flexibly selected according to actual installation needs, which improves the versatility and installation convenience of the bracket.

[0011] Optionally, the second fixing mechanism includes: The second bent piece is made of the same material as the first bent piece, and the second bent piece is disposed on the side of one side of the bracket body. The second fixing plate is disposed on the second bending piece; The second fixing buckle is located on the side of the bracket body opposite to the position of the second bent piece; The second fixing ring is disposed on the second fixing plate and fastened with the second fixing buckle. When the second fixing plate is fastened with the second fixing buckle, the second fixing plate blocks the placement slot opening of the bracket body.

[0012] By adopting the above technical solution, the second bending piece also has good flexibility, making it easy to flip the second fixing plate; by the engagement of the second fixing buckle and the second fixing ring, the second fixing plate can be quickly fixed, so that the second fixing plate covers the opening of the placement slot, thereby firmly confining the wire harness in the placement slot and preventing the wire harness from coming out of the placement slot; at the same time, the snap-fit ​​structure facilitates the later inspection and replacement, and the operation is simple and efficient.

[0013] Optionally, the third fixing mechanism includes: The third bending piece is made of the same material as the first bending piece, and the third bending piece is disposed on the side of the mounting substrate. The third fixing plate is disposed on the third bending piece; The third fixing buckle is disposed on the side of the mounting base plate opposite to the position of the third bent piece; The third fixing ring is disposed on the third fixing plate and fastened with the third fixing buckle. When the third fixing plate is fastened with the third fixing buckle, the third fixing plate blocks the opening of the mounting groove of the mounting base plate.

[0014] By adopting the above technical solution, the structure of the third fixing mechanism is similar to that of the second fixing mechanism. The use of the same material for the third bending piece ensures the flexibility of flipping. The third fixing plate is quickly fixed by the engagement of the third fixing buckle and the third fixing ring. This can firmly restrict the end of the wire harness in the mounting groove, preventing the end of the wire harness from shaking or shifting during vehicle operation, and further ensuring the stability of the wire harness connection.

[0015] Optionally, a partition plate is provided on the bottom wall of the placement groove of the bracket body. Several partition plates are provided according to different types of wires in the wire harness. Several partition plates are evenly distributed along the width direction of the bracket body. Separation plates corresponding to the position and number of partition plates are provided on the mounting base plate.

[0016] By adopting the above technical solution, the partition plate divides the space in the placement slot into several independent areas, which can classify and place different types of wires in the wire harness (such as power lines, signal lines, control lines, etc.) to avoid different types of wires from getting tangled or squeezed together. At the same time, the separation plate on the mounting base corresponds one-to-one with the partition plate to ensure that the wire harness maintains its classified state as it extends from the placement slot to the mounting slot. This not only facilitates later inspection and maintenance, but also reduces mutual interference between different wires and ensures the transmission performance of the wire harness.

[0017] Optionally, the separation plate on the mounting base plate divides the space on the mounting base plate into several wiring channels, and the third fixing plate is provided with a clearance groove corresponding to the number of wiring channels. The clearance groove is used to make way for the connector at the end of the wire harness.

[0018] By adopting the above technical solution, the wiring channel formed by the separation plate makes the wiring at the ends of various types of wire harnesses more regular and avoids them from intersecting; the clearance groove on the third fixing plate can provide clearance space for the connector at the end of the wire harness, preventing the connector from being squeezed or damaged when the third fixing plate is fastened, while ensuring that the third fixing plate can fit tightly against the mounting base plate and ensure the fixing effect on the ends of the wire harness.

[0019] Optionally, a first limiting post is provided on the side of the bracket body. The first limiting post is located on both sides of the second bent piece. A first limiting hole is provided on the second fixing plate. When the second fixing plate is fastened with the second fixing buckle, the first limiting post is inserted into the first limiting hole.

[0020] By adopting the above technical solution, after the second fixing plate is fastened and fixed with the second fixing buckle, the first limiting post is inserted into the first limiting hole, which can limit the second fixing plate and prevent the second fixing plate from shifting or shaking due to vibration during vehicle operation. This further improves the fixing stability of the second fixing plate for the wire harness in the placement slot and avoids the wire harness from becoming loose due to the displacement of the second fixing plate.

[0021] Optionally, a second limiting post is provided on the side of the mounting base plate. The second limiting post is located on both sides of the third bent piece. A second limiting hole is provided on the third fixing plate. When the third fixing plate is fastened with the third fixing buckle, the second limiting post is inserted into the second limiting hole.

[0022] By adopting the above technical solution, similar to the cooperation principle of the first limiting post and the first limiting hole, the cooperation of the second limiting post and the second limiting hole can effectively limit the third fixing plate after it is fastened, prevent the third fixing plate from shifting when the vehicle vibrates, and ensure that the third fixing plate is always tightly attached to the mounting base plate, thereby stabilizing the end of the wire harness, ensuring the stability of the wire harness connection end, and reducing the loosening of the connection or damage to the wire body caused by the end shaking.

[0023] Optionally, reinforcing ribs are provided on the surface of the second fixing plate.

[0024] By adopting the above technical solution, the reinforcing ribs can effectively enhance the structural strength and rigidity of the second fixing plate, preventing the second fixing plate from deforming or breaking due to factors such as vehicle vibration and external force during long-term use, thus extending the service life of the second fixing plate. At the same time, it ensures the shielding and fixing effect on the wire harness in the placement slot, ensuring the overall stability of the bracket.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The bracket body is securely installed on the vehicle by the first fixing mechanism, and the second and third fixing mechanisms fix the main body and end of the wiring harness in the placement groove and the installation groove, respectively. The displacement of the wiring harness is restricted in multiple directions, which greatly reduces the shaking of the wiring harness during vehicle operation, avoids damage and breakage caused by friction between the wiring harness and other components, and ensures the safety of the vehicle's electrical system. 2. The bracket body's bending section at the end of the bracket body achieves multi-angle rotation through the first bending piece made of thermoplastic polyurethane elastomer material, which can flexibly adapt to the complex wiring harness routing direction inside the vehicle, avoid stress concentration caused by forced bending of the wiring harness, further reduce the risk of wiring harness damage, and improve the applicability of the bracket. 3. The overall structural stability and service life of the bracket are enhanced by the cooperation of the first limiting post and the first limiting hole, the second limiting post and the second limiting hole, and the reinforcing ribs on the second fixing plate. The first fixing mechanism provides two methods: bolt fixing and threaded connection. The second and third fixing mechanisms adopt a snap-fit ​​structure, which not only ensures the reliability of fixing, but also simplifies the installation and disassembly operation, and improves the versatility and ease of use of the bracket.

The second fixing plate 52 is provided with first limiting holes 11 corresponding to the positions of the first limiting posts 10. When the second fixing plate 52 is fastened with the second fixing buckle 53, the first limiting posts 10 are inserted into the first limiting holes 11 to limit the second fixing plate 52 and prevent it from shifting. In addition, the surface of the second fixing plate 52 is integrally formed with reinforcing ribs. The reinforcing ribs are arranged along the length direction of the second fixing plate 52 to enhance the structural strength of the second fixing plate 52.

[0035] Reference Figure 1 and Figure 2 The third fixing mechanism 35 has a similar structure to the second fixing mechanism 5, including a third bent piece 351, a third fixing plate 352, a third fixing buckle 353, and a third fixing ring 354.

The third fixing ring 354 is fixed to the third fixing plate 352 and is adapted to the third fixing buckle 353. After fastening, the third fixing plate 352 covers the opening of the mounting groove 33, thereby fixing the end of the wire harness.

[0036] Reference Figure 1 and Figure 2 The mounting base plate 32 is fixed with second limiting posts 12 on both sides. The second limiting posts 12 are located on both sides of the third bending piece 351. The third fixing plate 352 is provided with second limiting holes 13 corresponding to the second limiting posts 12. When fastened, the second limiting posts 12 are inserted into the second limiting holes 13 to improve the fixing stability of the third fixing plate 352.

[0037] Reference Figure 1 and Figure 2 Multiple partition plates 6 are vertically fixed on the bottom wall of the placement groove 2 of the bracket body 1. The partition plates 6 are evenly distributed along the width direction of the bracket body 1, dividing the placement groove 2 into multiple independent accommodating areas for classifying and placing different types of wires. Separation plates 7, corresponding to the position and number of partition plates 6, are fixed in the mounting groove 33 of the mounting base plate 32. The separation plates 7 divide the mounting groove 33 into multiple wiring channels 8, each corresponding to one of the accommodating areas, so that the wire harnesses remain classified when extending from the placement groove 2 to the mounting groove 33. The third fixing plate 352 has clearance grooves 9 corresponding to the number of wiring channels 8. The position of the clearance grooves 9 corresponds to the wiring channels 8. When the third fixing plate 352 is fastened, the connectors at the ends of the wire harnesses can be accommodated in the clearance grooves 9, avoiding compression.

[0038] The working principle of this application embodiment is as follows: During installation, the bracket body 1 is first fixed to the vehicle using the first fixing plate 41 or fixing ring 43 in the first fixing mechanism 4, according to the installation location and fixing requirements inside the vehicle. Then, the wire harness bodies are placed in the respective independent areas of the placement slot 2 according to their type, and the wire harness ends are placed into the wiring channels 8 of the mounting base plate 32, and the wire harness connection ends are aligned with the vehicle interface by passing through the connection holes 34.

[0039] Flip the second fixing plate 52 so that the second fixing buckle 54 and the second fixing buckle 53 are engaged, and the first limiting post 10 is inserted into the first limiting hole 11 to fix the main body of the wire harness; then flip the third fixing plate 352 so that the third fixing buckle 354 and the third fixing buckle 353 are engaged, and the second limiting post 12 is inserted into the second limiting hole 13, and the connector at the end of the wire harness is accommodated in the relief groove 9 to complete the fixing of the end of the wire harness.

[0040] Based on the actual routing direction of the wiring harness, the angle of the mounting base plate 32 is adjusted by the first bending piece 31 to ensure smooth connection of the wiring harness connection end to the vehicle interface, avoiding forced bending of the wiring harness. During vehicle operation, the bracket restricts the swaying of the wiring harness through multi-directional fixation, and the partition plate 6 and separation plate 7 ensure that the wiring harness is neatly classified, effectively preventing damage and breakage of the wiring harness and ensuring the safety of the electrical system.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
