3 can play the role of similar vane heat dissipating, in the case where the rotation of motor shaft 200 drives, reinforcing rib 3 can with agitation air, thus
It can radiate to components such as bearings inside bearing chamber, improve the heat dissipation performance of motor 1000, and structure is simple, design
It is ingenious.
Some specific embodiments according to the present utility model, one end of the length direction of reinforcing rib 3 extend to and waterproof top
The inner wall of plate 1 is connected, and the other end of the length direction of reinforcing rib 3 extends to one end with the separate water-proof top plate 1 of waterproof cover 2
Concordantly.Thus, it is possible to increase the length of reinforcing rib 3, be conducive to the structural strength for further improving waterproof case 100, further
Ground reduces the probability of the damage of waterproof case 100.The ability of 3 agitation air of reinforcing rib, Jin Erjin can be further improved simultaneously
Improve to one step the heat dissipation performance of motor 1000.
Here, it should be noted that the length direction of the reinforcing rib 3 in the application can be understood as the center of waterproof cover 2
The extending direction of axis.For example, the X-direction in Fig. 9 can be interpreted as the length direction of reinforcing rib 3.
In some specific embodiments of the utility model, multiple reinforcing ribs 3 are evenly-spaced in the circumferential direction of waterproof cover 2
Setting.Multiple equally distributed reinforcing ribs 3 can make waterproof cover 2 have good symmetry, can improve waterproof well
The stability and balance of part 100 in high-speed rotation process.
Some embodiments according to the present utility model, multiple reinforcing ribs 3 are radially distributed centered on mounting hole 11.Knot
Structure is simple, easy to process.
Some embodiments according to the present utility model, reinforcing rib 3 are formed as plate-like structure or curved configuration.For example,
In the example of Fig. 1 and Fig. 8, reinforcing rib 3 is formed as plate-like structure.For another example, in the example of hgure 5, reinforcing rib 3 is formed as bent
Linear structure.In the present embodiment, reinforcing rib 3 can be formed as arc or S-shaped.Structure is simple, easy to process.
It is, of course, understood that reinforcing rib 3 can also be formed as irregular shape.
In some embodiments of the utility model, on the direction far from water-proof top plate 1, the width of reinforcing rib 3 is gradually
Reduce.Referring to Fig. 9 and Figure 10, the end cap 300 of motor 1000 is equipped with lug boss 301, and waterproof case 100 is being assembled to motor
When on 1000, at least part of lug boss 301 is protruded into waterproof cover 2.It sets the width of reinforcing rib 3 to far from waterproof top
