Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figures 1-3 , a wire for a motor of an aerial work platform vehicle resistant to bending and torsion includes a wire material 1, a first twisted pair group 3, a cable 5, and three core wires 6. The first twisted pair group 3 is formed by twisting two control signal lines. The first twisted pair group 3, the cable 5, and the three core wires 6 penetrate through the wire material 1; it includes an elliptical filling 13 and multiple circular fillings 4. The elliptical filling 13 is located in the gap between the core wire 6 and the cable 5, and the multiple circular fillings 4 are located in the gaps between the first twisted pair group 3, the cable 5, and the core wire 6. The elliptical filling 13 and the multiple circular fillings 4 penetrate through the wire material 1; the power line and the control line are integrated into one cable. It includes three large cross-section wires to connect a three-phase motor to transmit power, and five pairs of twisted pair groups to provide control signals; it is pre-twisted with high-strength reinforced PP ropes to improve the tensile strength of the product and the roundness of the wire material; the control signal line pair uses a small pitch twist to improve the tensile strength of the product and the anti-electromagnetic signal interference.

[0017] As Figures 1-3, the cable 5 includes an aluminum foil 10, four second twisted pairs 11, and five small fillers 12. The second twisted pairs 11 are formed by twisting two control signal lines. The four second twisted pairs 11 run through the cable 5, and the five small fillers 12 run through the gaps between the four second twisted pairs 11 and the aluminum foil 10. The cable uses a pitch-stranded fine copper wire conductor. The conductor is soft, reducing the stress during movement and being resistant to bending and torsion. To improve the bending and torsion resistance, the conductor uses a small pitch composite-stranded fine copper wire conductor. High mechanical property materials are used for insulation, filling, and sheath, which can meet more than 200,000 times of bending and torsion movements without breaking. The four pairs of signal groups are cabled once. During cabling, a back-twisting machine is needed to perform partial back-twisting to reduce the stress during cabling, and an additional shielding layer is added to improve signal resistance. After braiding, it is cabled with another pair of twisted signal lines and three power lines. Cabling also requires back-twisting to release stress.

[0018] Such as Figures 1-3 , the cable 5 includes a polyester tape 8 and a braided mesh 9. The braided mesh 9 is wrapped outside the aluminum foil 10, and the polyester tape 8 is wrapped outside the braided mesh 9. The insulation uses a cross-linked polyolefin material, which is resistant to high temperatures of 150 °C, avoiding insulation heat aging during operation. Selecting a high-hardness and good mechanical property grade of the material can provide better support and protect the conductor. Using materials with good heat and aging resistance for insulation can avoid insulation aging and cracking caused by large current heating of the power line during operation.

[0019] Such as Figures 1-3 , the wire 1 includes a non-woven fabric 7. The non-woven fabric 7 is wrapped outside the first twisted pair 3, the circular filler 4, the cable 5, and the core wire 6. A high-strength modified PVC material is selected, which is more cost-effective while meeting the sheath protection performance requirements such as abrasion resistance, oil resistance, ultraviolet resistance, and water resistance.

[0020] Such as Figures 1-3 , the wire 1 includes an outer sheath 2. The outer sheath 2 is wrapped outside the non-woven fabric 7. Special materials are used for the sheath to ensure material abrasion resistance, bending and torsion resistance, and resistance to harsh environments such as outdoor oil, water, and ultraviolet rays.

[0021] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
