AI Technical Summary
The existing motor cable terminal blocks for forklift motor drive assemblies are not impact-resistant, have many installation steps and low waterproof rating, and cannot meet the requirements of heavy-duty handling and frequent start-stop operations.
It adopts an integrated motor rear end cover and motor rear cover plate, uses metal parts instead of plastic terminal blocks, and improves the waterproof rating with cable fixing heads, simplifying the installation process.
This technology enhances the motor's anti-collision capabilities, reduces installation steps, improves the waterproof rating to IP67, and extends the motor's service life.

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0023] Please refer to Figures 1-3 , the anti-collision structure of the motor driving assembly for the electric forklift, comprising a motor casing 1, an integrated motor rear end cover 2, a motor rear cover plate 3, a motor cable 4 and a cable fixing head 5.
[0024] The integrated motor rear end cover 2 is provided with cable fixing head 5 installation thread on the upper end face, and the integrated motor rear end cover 2 is provided with motor rear cover plate 3 installation thread on the side end face, and the motor cable 4 is threaded on the integrated motor rear end cover 2.
[0025] When in use, the three-phase motor cable exits from inside the motor through the cable fixing head 5 installed on the integrated motor rear end cover 2. After the three-phase cable is installed and fixed, the motor rear cover 3 is finally installed on the integrated motor rear end cover 2. The integrated motor rear end cover 2 and the motor rear cover 3 are made of metal and play a protective role against possible collisions when the electric forklift is working.
[0026] This structure has the following advantages:
[0027] 1. The integrated motor rear end cover 2 is made of metal, which is high in strength and collision-resistant, avoiding the safety hazards caused by motor collision and improving the service life of the motor;
[0028] 2. This anti-collision structure has fewer parts, reducing installation steps, making it easier to install, and shortening the working time;
[0029] 3. The motor's three-phase wires exit through cable fixing head 5, with a high waterproof rating of IP67.
[0030] In the description herein, it should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
