DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2The embodiment of the utility model provides a technical solution: a driving motor controller mounting bracket structure, including a controller bracket assembly 1, the controller bracket assembly 1 includes a floor body 2, a floor beam 3, a floor longitudinal beam 4, a first mounting bracket 5 and a second mounting bracket 6, the floor beam 3 is horizontally mounted on the top of the floor body 2, the floor longitudinal beam 4 is vertically mounted on the top of the floor body 2, the first mounting bracket 5 and the second mounting bracket 6 are both vertically mounted on the top of the floor beam 3, the first mounting bracket 5 is located on the left side of the second mounting bracket 6, and the controller body 7 is installed on the top of the first mounting bracket 5 and the second mounting bracket 6.

[0021] Effectively, the first mounting bracket 5 and the second mounting bracket 6 are both in a semi-closed structure, and the first mounting bracket 5 and the second mounting bracket 6 both include an assembly surface 9 and an arcuate surface 10, the assembly surface 9 is installed at both ends of the arcuate surface 10, the assembly surface 9 and the arcuate surface 10 are a smooth transition and an integral stamping structure, and the assembly surface 9 is fixedly connected to the controller body 7 by a fastening bolt 13.

[0022] Furthermore, welding flanges 11 extend from both sides of the first mounting bracket 5 and the second mounting bracket 6, and the welding flanges 11 are in a rectangular structure. The first mounting bracket 5 and the second mounting bracket 6 are welded to the floor body 2 and the floor beam 3 through the welding flanges 11. The first mounting bracket 5, the second mounting bracket 6 and the floor beam 3 are combined to form a cross structure. Such a cross structure forms a force conduction and dispersion effect, weakens the local stress concentration of the controller bracket, and reduces the risk of fatigue damage.

[0023] Furthermore, reinforcing ribs 12 are provided on the surfaces of the first mounting bracket 5 and the second mounting bracket 6. The reinforcing ribs 12 are provided to strengthen the mounting bracket structure.

[0024] Furthermore, the floor body 2 has reinforcement grooves 8 formed on its surface, and the structure of the floor body 2 can be strengthened by forming the reinforcement grooves 8 .

[0025] Working principle: When in use, the staff first installs the controller body 7 on the top of the first mounting bracket 5 and the second mounting bracket 6 by tightening the bolts 13 to complete the installation. Since the first mounting bracket 5, the second mounting bracket 6 and the floor cross beam 3 form a cross structure supported on the floor body 2, the force-bearing area is increased, and the guide force is transmitted to the stronger floor longitudinal beam 4 structure. Such a structure forms a force conduction and dispersion effect, weakens the local stress concentration of the controller bracket, and reduces the risk of fatigue damage.

[0026] The utility model comprises: 1. a controller bracket assembly; 2. a floor body; 3. a floor crossbeam; 4. a floor longitudinal beam; 5. a first mounting bracket; 6. a second mounting bracket; 7. a controller body; 8. a reinforcing rib groove; 9. an assembly surface; 10. an arc-shaped surface; 11. a welding flange; 12. a reinforcing rib; 13. a fastening bolt. All the components are common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
