Description

Technical Field

[0001] This utility model relates to the technical field of wire harness wrapping devices, specifically a wrapping device for wire harnesses in new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the degree of electrification of vehicles is constantly increasing. As a key component for power and signal transmission in new energy vehicles, the safety and reliability of wiring harnesses are of paramount importance.

[0003] Publication No. CN111874761A discloses an electric vehicle wiring harness wrapping device, including a worktable. The worktable has a slide rail on its surface, a support base on the slide rail surface, a mounting plate on the support base surface, a retaining ring on the mounting plate surface, a top block inside the retaining ring, a cam on the retaining ring surface, a gear on the side of the cam, a rack on the surface of the gear, and a drive spring on the surface of the rack. This electric vehicle wiring harness wrapping device improves the wiring harness arrangement effect through the cooperation between the mounting plates, ensuring the neatness of the wiring harness during wrapping and improving the wrapping effect. The cooperation between the retaining ring and the cam, the gear and the rack, and the drive spring and the rack make the installation and removal of the wiring harness more convenient and faster, improving the efficiency of wiring harness wrapping processing.

[0004] As shown in the above technical solution, although the device improves the wiring harness arrangement effect and ensures the neatness of the wiring harness during wrapping by cooperating between the mounting plates, and wraps the wiring harness with a wrapping box, in actual use, the wrapping box will wrap the wrapping tape layer by layer around the wiring harness. For longer wiring harnesses, the wrapping time is too long. Moreover, when repairing the wiring harness, it is necessary to cut or peel off the wrapping tape layer by layer to expose the internal wiring harness. The cut wrapping tape cannot be reused, which increases the repair cost of automotive wiring harnesses. Peeling off the wrapping tape layer by layer takes a long time, which increases the time cost of automotive wiring harness repair. In addition, the peeled wrapping tape is prone to losing its adhesiveness, and it is necessary to determine whether it can be reused based on the actual situation. Utility Model Content

[0008] An outer protective sleeve, which wraps around the wire harness body, is used to protect the wire harness body from damage caused by external factors;

[0009] A connecting component is installed at the end of the outer protective sleeve. The connecting component is used to connect the two ends of the outer protective sleeve together, so that the outer protective sleeve can wrap the wire harness body.

[0010] Preferably, the connecting assembly includes two sealing strips, which are respectively fixedly installed at both ends of the outer protective sleeve. Multiple symmetrical mounting seats are evenly installed on each of the two sealing strips, and the same connecting rod is movably installed on the multiple mounting seats.

[0016] Beneficial effects

[0017] This utility model provides a wrapping device for wiring harnesses in new energy vehicles. Compared with the prior art, it has the following advantages:

[0018] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-4 This utility model provides the following two technical solutions:

[0027] First embodiment: A wrapping device for a new energy vehicle wiring harness, comprising:

[0028] Wiring harness body 1, which is used to transmit the power and various signals generated during the operation of new energy vehicles;

[0029] Outer protective sleeve 2, the outer protective sleeve 2 wraps around the wire harness body 1, the outer protective sleeve 2 is used to protect the wire harness body 1 from damage by external factors;

[0030] The connecting component 3 is installed at the end of the outer protective sleeve 2. The connecting component 3 includes two sealing strips 31, which are fixedly installed at both ends of the outer protective sleeve 2. Multiple symmetrical mounting seats 32 are evenly installed on both sealing strips 31. The same connecting rod 33 is movably installed on the multiple mounting seats 32. The connecting component 3 is used to connect the two ends of the outer protective sleeve 2 together, so that the outer protective sleeve 2 can wrap the wire harness body 1.

[0031] Both ends of the outer protective sleeve 2 are movably mounted with limiting components 4 for fixing the two ends of the connecting rod 33. The limiting components 4 include a clamping plate 41 and a winding seat 43. Both ends of the clamping plate 41 are threaded with limiting bolts 42. Both limiting bolts 42 are movably mounted on the outer protective sleeve 2. The top of the clamping plate 41 is fixedly mounted on the winding seat 43. A through hole 44 is opened on the winding seat 43.

[0032] The wiring harness body 1 serves as the transmission carrier for electricity and various signals during the operation of new energy vehicles. Its internal wires, according to different functional requirements, transmit electrical energy and control signals, sensor signals, etc. Through the conductivity of the wires, electrical connections are achieved between various components of the new energy vehicle, ensuring its normal operation. The outer protective sleeve 2 wraps around the wiring harness body 1. Its material typically possesses certain mechanical strength, insulation, and weather resistance. Mechanical strength prevents external mechanical damage, such as compression and impact; insulation prevents the wires of the wiring harness body 1 from contacting external conductors, preventing electrical faults such as short circuits; weather resistance allows it to adapt to different environmental conditions, such as temperature changes, humidity, and light, protecting the wiring harness body 1 from environmental factors. The two sealing strips 31 of the connecting component 3... The outer protective sleeve 2 is not installed at the end. Multiple mounting seats 32 on the sealing strip 31 are symmetrically distributed. The connecting rod 33 is movably installed on multiple mounting seats 32. The two ends of the outer protective sleeve 2 are connected by the connecting rod 33. This connection method allows the outer protective sleeve 2 to be tightly wrapped around the wire harness body 1, preventing the ends of the outer protective sleeve 2 from loosening, thereby better exerting the protective function of the outer protective sleeve 2. The clamp 41 in the limiting assembly 4 is movably installed on the outer protective sleeve 2 by the limiting bolts 42 at both ends. The clamp 41 can fix the two ends of the connecting rod 33 to prevent the connecting rod 33 from shifting or loosening during use. The winding seat 43 is fixed on the top of the clamp 41, and the through hole 44 on it can be used to wind the two ends of the connecting rod 33, further ensuring the stability of the connecting rod 33 during use.

[0033] In this embodiment, the outer protective sleeve 2 effectively protects the main body 1 of the wiring harness from external mechanical damage, electrical interference, and environmental factors, extending the service life of the wiring harness and improving the reliability of the new energy vehicle operation. The design of the connecting component 3 makes the installation and disassembly of the outer protective sleeve 2 more convenient. After maintenance, the disassembled connecting component 3 and outer protective sleeve 3 can be re-wrapped onto the main body 2 of the wiring harness, realizing the reuse of the wrapping device and reducing maintenance costs. Through the cooperation of the connecting rod 33 and the mounting base 32, the two ends of the outer protective sleeve 2 can be quickly connected or separated, which facilitates the maintenance and repair of the main body 1 of the wiring harness. The limiting component 4 can effectively fix the two ends of the connecting rod 33 to prevent it from loosening, thereby ensuring the connection stability of the two ends of the outer protective sleeve 2. The stable connection helps to maintain the tight wrapping of the wiring harness main body 1 by the outer protective sleeve 2, further improving the protection effect.

[0034] The second implementation method differs from the first implementation method in that: multiple outer protective strips 5 are evenly installed on the outer side of the outer protective sleeve 2, and multiple ball bearings 6 are rotatably installed on each of the multiple outer protective strips 5.

[0035] An insulating layer 7 is fixedly installed on the inner end of the outer protective sleeve 2, and the insulating layer 7 is located between the main body of the wire harness 1 and the outer protective sleeve 2.

[0036] Multiple drying strips 8 are fixedly installed inside the insulation layer 7 in a centrally symmetrical distribution.

[0037] The outer protective strip 5 is evenly installed on the outer side of the outer protective sleeve 2, increasing the mechanical strength of the outer protective sleeve 2. The rotating ball bearings 6 allow the outer protective sleeve 2 to disperse external forces when subjected to external forces, reducing the pressure and friction directly experienced by the outer protective sleeve 2. When the outer protective sleeve 2 comes into contact with other objects and undergoes relative movement, the ball bearings 6 can convert sliding friction into rolling friction, reducing the coefficient of friction and minimizing wear on the outer protective sleeve 2. The insulating layer 7 is fixedly installed on the inner side of the outer protective sleeve 2 between it and the wire harness body 1. Its main function is to prevent friction between the wires of the wire harness body 1 and the outer protective sleeve 2. The insulation layer 7 is typically made of a material with good insulation properties, which can effectively isolate the current in the main body 1 of the wiring harness and ensure the safe operation of the electrical system. The drying strips 8 are centrally symmetrically distributed within the insulation layer 7. Their working principle is to absorb moisture within the insulation layer 7 by utilizing the water absorption properties of the drying strips 8. During the operation of new energy vehicles, environmental factors may cause moisture to appear within the insulation layer 7. The drying strips 8 can effectively absorb this moisture, maintain a dry environment within the insulation layer 7, and prevent moisture from affecting the insulation performance of the insulation layer 7 and the main body 1 of the wiring harness.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] In use, the outer protective sleeve 2 is placed on the wire harness body 1, ensuring that the outer protective sleeve 2 completely covers the wire harness body 1 and the insulation layer 7 is located between the two. The two sealing strips 31 at both ends of the outer protective sleeve 2 are aligned for subsequent connection. The connecting rod 33 is passed through the multiple mounting seats 32 on the two sealing strips 31 at the same time, so that the outer protective sleeve 2 tightly wraps the wire harness body 1. The clamping plate 41 is movably installed on the outer protective sleeve 2 through the limiting bolts 42 at both ends. The clamping plate 41 clamps the two ends of the connecting rod 33 to prevent the connecting rod 33 from shifting or loosening. The two ends of the connecting rod 33 can be wound around using the through holes 44 on the winding seat 43 to further enhance the stability of the connecting rod 33. The wrapped wire harness body 1 is installed in the corresponding position of the new energy vehicle to ensure that it can transmit power and signals normally, and the outer protective sleeve 2 can effectively protect the wire harness body 1 from external factors.
