[0002] New energy tractor vehicles are heavy-duty vehicles that use clean energy sources such as electricity and hydrogen as power sources and are driven by electric motors to transport goods. With the widespread application of new energy tractor vehicles, the arrangement of their high-voltage wiring harnesses has gradually become a technical challenge.

[0003] In existing technologies, high-voltage wiring harnesses are mostly secured and arranged using a single fixing bracket or clip. While this arrangement method is robust and practical, users typically need to use multiple fixing brackets to secure and fix the high-voltage wiring harnesses during actual installation, making maintenance and replacement inconvenient. Therefore, this utility model aims to provide a high-voltage wiring harness arrangement device for new energy tractor vehicles that can accommodate multiple bundles of high-voltage wiring harnesses without requiring multiple fixing brackets.

[0018] Compared with the prior art, this utility model provides a high-voltage wiring harness arrangement device for new energy tractor vehicles, which has the following beneficial effects:

[0019] 1. This utility model uses clockwise rotation of the rotating part to apply greater tension to the binding rope, resulting in a smaller diameter of the rope opening.

[0026] 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.

[0027] Example: Please refer to Figures 1 to 3 According to an embodiment of the present invention, a technical solution is provided: a high-voltage wiring harness arrangement device for a new energy tractor includes an insulating frame 1, on which a plurality of rotating parts 2 are rotatably arranged at intervals along its length on its peripheral sidewall; a binding rope 3, which is respectively connected between each pair of adjacent rotating parts 2 for binding and fixing multiple bundles of high-voltage wiring harnesses; and a locking mechanism, which is disposed between the insulating frame 1 and the rotating parts 2 and is used to fix the rotating parts 2 relative to the insulating frame 1 to restrict or allow the rotating parts 2 to rotate along their axis.

[0028] The high-voltage wiring harness arrangement device for new energy tractors with the above-described structure allows for the following steps when a user needs to arrange the high-voltage wiring harness: First, the rotating part 2 is fixed to the insulating frame 1 via a locking mechanism to ensure that the rotating part 2 will not rotate unexpectedly due to external interference during the arrangement process. Then, multiple bundles of high-voltage wiring harnesses are sequentially arranged between the openings of corresponding binding ropes 3. To accommodate the diameter of the corresponding high-voltage wiring harnesses, the locking mechanism allows the rotating part 2 to rotate. When the rotating part 2 rotates clockwise, it applies greater tension to at least one binding rope 3 connected to its peripheral wall (when there are two binding ropes 3 on the rotating part 2, it can simultaneously tighten the binding ropes 3 on both sides), resulting in a smaller opening diameter. Conversely, when rotating counterclockwise, the rotating part 2 loosens the binding ropes 3, thereby increasing the opening diameter to accommodate high-voltage wiring harnesses of different diameters. Finally, the locking mechanism restricts the rotation of the rotating part 2 to ensure stable arrangement of the multiple bundles of high-voltage wiring harnesses.

[0029] In this embodiment, the locking mechanism includes a locking rod 4, a limiting part 5, and a spring 6; a locking cavity 7 is provided inside the insulating frame 1, and the locking rod 4 movably passes through the top of the insulating frame 1 and extends to the locking cavity 7; the limiting part 5 is movably disposed in the locking cavity 7, and the spring 6 is movably sleeved on the limiting part 5, with the spring 6 located between the limiting part 5 and the top wall of the locking cavity 7; a plurality of locking grooves 12 are provided circumferentially on the peripheral side wall of the rotating part 2, and the locking grooves 12 are suitable for the locking rod 4 to be movably inserted; with this configuration, when the user When it is necessary to restrict or allow the rotating part 2 to rotate along its axis, firstly, by applying an appropriate force to pull the locking rod 4, it overcomes the elastic force of the spring 6, so that the locking rod 4 is moved out of the locking groove 12 of the rotating part 2. At this time, the rotating part 2 can rotate freely. When the rotating part 2 rotates to the desired position, the user releases the locking rod 4, and the elastic force of the spring 6 will push the limiting part 5 to drive the locking rod 4 back to its original position, so that it is re-inserted into the locking groove 12 of the rotating part 2, thereby fixing the rotating part 2 in the current position.

[0030] In this embodiment, a lifting part 8 for pulling is arranged at the top of the locking rod 4; with this arrangement, when the user needs to pull the locking rod 4, the lifting part 8 will provide the user with a fulcrum to pull the locking rod 4, so that the user can pull the locking rod 4.

[0031] In this embodiment, each end of the insulating frame 1 is provided with a mounting plate 9, and the mounting plate 9 is provided with mounting holes 10. The mounting holes 10 are used to fix the insulating frame 1 to the body or other structure of the new energy tractor. The mounting plate 9 is connected to the vehicle body by bolts or other appropriate fasteners, thereby ensuring that the insulating frame 1 remains stable during use and will not be displaced due to vibration or external force.

[0032] In this embodiment, the insulating frame 1 is provided with a plurality of material-saving grooves 11; the material-saving grooves 11 are used to reduce the overall weight of the insulating frame 1, effectively optimize the use of materials, and reduce unnecessary weight burden.

[0033] In this embodiment, two adjacent binding ropes 3 are staggered and arranged alternately up and down. When the binding ropes 3 are arranged alternately, the pressure and tension borne by each binding rope 3 will be more balanced, avoiding excessive concentration in one direction and reducing the risk of wire harness deformation or damage.

[0034] In this embodiment, the rotating part 2 movably passes through the insulating frame 1, and both ends of the rotating part 2 protrude from the insulating frame 1 respectively. A binding rope 3 is arranged on the rotating part 2 on both sides of the insulating frame 1. With this arrangement, both ends of the rotating part 2 can be selectively locked by the locking mechanism. In particular, by adding a binding rope 3 on one side, the high-voltage line harness is more stably bound.

[0035] In this embodiment, the mounting plate 9 and the insulating frame 1 are integrally formed, and the mounting hole 10 has an elongated oval structure. With this configuration, the long axis of the mounting hole 10 is parallel to the length direction of the insulating frame 1, providing users with greater installation and adjustment space to meet the needs of different installation conditions.

[0036] In this embodiment, the restraint rope 3 is made of a stretchable elastic material and its surface is covered with an insulating protective layer; with this configuration, the stretchability of the elastic material allows the restraint rope 3 to adapt to the dynamic changes of the high-voltage harness, preventing the harness from becoming loose or damaged due to changes in the external environment.

[0037] In this embodiment, the restraint rope 3 is made of flame-retardant material; specifically, the flame-retardant material can be specially treated polyester fiber or aramid fiber, which can effectively suppress the spread of flames and reduce the occurrence of fire accidents in high temperature or fire source environments.

[0038] Working principle: When a user needs to arrange high-voltage wire harnesses, firstly, the rotating part 2 is fixed to the insulating frame 1 by the locking mechanism to ensure that the rotating part 2 will not rotate unexpectedly due to external interference during the arrangement of the high-voltage wire harnesses. Then, multiple bundles of high-voltage wire harnesses are arranged sequentially between the rope openings of the corresponding multiple binding ropes 3. At this time, in order to accommodate the diameter of the corresponding high-voltage wire harnesses, the locking rod 4 is moved out of the locking groove 12 of the rotating part 2 to allow the rotating part 2 to rotate freely. When the rotating part 2 rotates clockwise, the rotating part 2 will apply greater tension to the binding ropes 3, resulting in a reduction in the diameter of the rope openings. Conversely, when rotating counterclockwise, the rotating part 2 loosens the binding rope 3, thereby increasing the diameter of the rope opening to accommodate high-voltage wire harnesses of different diameters. Subsequently, the rotation of the rotating part 2 is restricted by the locking mechanism to stably arrange multiple bundles of high-voltage wire harnesses. When the user needs to pull the locking rod 4, the lifting part 8 provides the user with a fulcrum to pull the locking rod 4. The mounting hole 10 is used to fix the insulation frame 1 to the body or other structure of the new energy tractor. The mounting plate 9 is connected to the vehicle body by bolts or other appropriate fasteners to ensure that the insulation frame 1 remains stable during use and will not be displaced due to vibration or external force. The material-saving groove 11 is used to reduce the overall weight of the insulation frame 1, effectively optimizing the use of materials and reducing unnecessary weight burden. When the binding ropes 3 are arranged alternately, the pressure and tension borne by each binding rope 3 will be more balanced, avoiding excessive concentration in one direction and reducing the risk of wire harness deformation or damage.

[0039] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
