DETAILED DESCRIPTION

[0028] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. This embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0029] like Figure 1-4As shown, the right flat fork tube 1 and the left flat fork tube 7 are arranged on the left and right sides of the vehicle respectively, extending forward and the front section is bent toward the center plane of the vehicle and fixedly connected to the flat fork shaft tube 10. The left hook 5 is fixedly connected to the rear end of the left flat fork tube 7 parallel to the center plane of the vehicle, and the right hook 4 is fixedly connected to the rear end of the right flat fork tube 1 parallel to the center plane of the vehicle. The right hook 4 is provided with a motor inlet hole 401 connected to the rear end notch on the right flat fork tube 1. The left vibration damping mounting plate 6 is fixedly connected above the left flat fork tube 7 and behind the bending position parallel to the center plane of the vehicle, and the arrangement of the right vibration damping mounting plate 2 corresponds to that of the left vibration damping mounting plate 6. The triangular angle formed by the overlap of the flat fork shaft tube 10 and the left flat fork tube 7 and the right flat fork tube 1 is fixedly connected by the flat fork tube reinforcement plate 9. The upper bending surface of the flat fork tube reinforcement plate 9 completely blocks the angle formed between the flat fork shaft tube 10 and the left flat fork tube 7 and the right flat fork tube 1, thereby strengthening the deformation resistance of the front end of the flat fork tube. The lower bending surface of the flat fork tube reinforcement plate 9 is shorter than the upper bending surface, leaving a routing space for the front end 14 of the motor line. The rear mudwall mounting plate 8 is arranged behind the flat fork tube reinforcement plate 9 and between the left flat fork tube 7 and the right flat fork tube 1, further increasing the strength of the flat fork tube. The protective shell mounting plate 12 is fixedly connected to the lower front side of the flat fork shaft tube 10, and the motor line passing notch of the protective shell mounting plate 12 faces forward. The motor line protective shell 13 is installed below the flat fork shaft tube 10 and is fastened from bottom to top to the bottom of the protective shell mounting plate 12 by two anti-theft screws 11 distributed on both sides of the center plane of the vehicle.

[0030] like Figure 3-4 As shown, the rear end 3 of the motor wire passes through the motor wire inlet hole 401 and enters the right flat fork tube, and is closely attached to the inner side of the right hook claw 4. This method hides the motor wire harness very well and has good protection capabilities for the rear end 3 of the motor wire. The front end 14 of the motor wire passes through the motor wire outlet hole 101, and bends and turns from the notch position in front of the protective shell mounting plate 12 to change the wiring direction.

[0031] like Figure 5-7As shown, the motor line protection shell includes a protection shell body 1301, folded edges 1307 vertically arranged on both sides of the protection shell body 1301, and a protection shell rear limit 1302 arranged at the rear end of the protection shell body 1301. The front end of the folded edge 1307 and the protection shell body 1301 form a front opening 1305 of the protection shell outlet groove, and the rear end of the folded edge 1307 and the protection shell rear limit 1302 form a rear opening 1306 of the protection shell outlet groove. The protection shell body 1301 is provided with two front and rear arranged water holes 1303 to facilitate the discharge of mud, sand and sewage. The folded edges 1307 on both sides of the motor line protection shell 13 are provided with mounting holes 1304, and the mounting holes 1304 are fastened to the bottom of the protection shell mounting plate 12 by anti-theft screws 11. The front opening 1305 of the protective shell outlet groove is concave, which is used for the front end 14 of the motor line to pass through. The folded edges 1307 on both sides of the motor line protective shell 13 are close to the lower edge after the left flat fork tube 7, the right flat fork tube 1 and the flat fork shaft tube 10 are fixed. After the motor line protective shell 13 is installed, it forms a cavity with only the front opening with the protective shell mounting plate 12, the flat fork shaft tube 10, the left flat fork tube 7, the right flat fork tube 1 and the flat fork tube reinforcement plate 9, which well protects the front end 14 of the motor line. After the front end 14 of the motor line passes through the motor line outlet hole 101, it enters the motor line protective shell 13 from the rear opening 1306 of the protective shell outlet groove, and finally passes through the front opening 1305 of the protective shell outlet groove and folds upward. The rear end of the flat fork tube reinforcement plate 9 is bent to form a reinforcement plate limit 901. The mutual cooperation and locking of the protective shell rear limit 1302 and the reinforcement plate limit 901 greatly reduces the installation operation intensity of the workers and also improves the anti-pry ability of the motor line protective shell 13.

[0032] Preferably, the anti-theft screw 11 is a pan head special-shaped slot screw. It is difficult to remove this screw with common tools on the market, but for the manufacturer's after-sales maintenance personnel equipped with special tools, the replacement of the motor wire protection shell 13 and the maintenance of the motor wiring harness are much easier.

[0033] The above specific implementation methods are only for illustrating the technical concept and structural features of the utility model, and the purpose is to enable relevant persons familiar with this technology to implement them accordingly. However, the above content does not limit the protection scope of the utility model. Any equivalent changes or modifications made based on the spirit of the utility model should fall within the protection scope of the utility model.
