[0022] 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.

[0023] Please see Figures 1-2This utility model provides a technical solution: an IP67 anti-collision structure for a forklift motor drive assembly, including a motor housing 1, an integrated anti-collision rear end cover 2 on the left side of the motor housing 1, a waterproof connector mounting thread 3 on the upper surface of the integrated anti-collision rear end cover 2, a waterproof connector 4 installed inside the waterproof connector mounting thread 3, motor UVW three-phase lead wires 5 leading out from the three sets of waterproof connectors 4 on the rear side, a signal plug lead wire 6 leading out from the single set of waterproof connectors 4 on the front side, and a motor rear cover plate 7 on the left side of the integrated anti-collision rear end cover 2.

[0024] To provide more comprehensive protection for the leads and related connections, and to improve the overall structure's impact resistance reliability, this invention includes four sets of waterproof connector mounting threads 3. These four sets of threads are used to mount the motor UVW three-phase leads 5 and signal plug-in leads 6 on the same plane. This design allows the motor UVW three-phase leads 5 and signal plug-in leads 6 to be arranged on the same plane, effectively preventing the lead-out parts from being impacted from different angles and directions when the electric forklift is in operation. This provides more comprehensive protection for the leads and related connections, and improves the overall structure's impact resistance reliability.

[0025] In order to improve the service life of the motor, this utility model is designed so that both the integrated anti-collision rear end cover 2 and the motor rear cover plate 7 are made of metal. Metal parts have high strength and can prevent collisions, thus avoiding safety hazards caused by motor damage due to collisions and improving the service life of the motor.

[0026] To improve the waterproof performance of the motor, this utility model features a three-phase UVW lead wire 5 that exits through a waterproof connector 4, effectively enhancing the waterproof performance and achieving an IP67 waterproof rating. This allows the motor to cope with complex working conditions such as humidity and high water content; adapt to harsh environments and ensure stable motor operation; reduce component damage caused by water ingress and extend motor life; avoid safety hazards such as leakage and fire, ensuring safety; enhance structural reliability and reduce maintenance costs and downtime.

[0027] During use, the motor UVW three-phase lead wire 5 and signal plug lead wire 6 are brought out from inside the motor through the waterproof connector 4 installed on the integrated anti-collision rear end cover 2. After the motor UVW three-phase lead wire 5 and signal plug lead wire 6 are installed and fixed, the motor rear cover plate 7 is installed on the integrated anti-collision rear end cover 2.

[0028] During use, this structure, thanks to the metal material of the integrated anti-collision rear end cover 2 and the motor rear cover plate 7, can resist impacts from different angles and surfaces during operation, protecting the motor from damage. At the same time, the IP67 waterproof rating can adapt to complex working conditions such as humidity and water, and the fewer parts can reduce the inconvenience of installation and maintenance.

[0029] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.
