Detailed ways

Below in conjunction with the accompanying drawings of the embodiments, the specific embodiments of the present utility model will be further described:

Please refer to FIGS. 1 to 4 , a motor cover plate 10 provided in this embodiment is used to cover the top of a motor box 20 , including a cover plate body 11 , and the cover plate body 11 is a hollow aluminum plate. The two ends are respectively inserted with support plates 12. The support plate 12 includes an inner fixed end 121 and an outer fixed end 122. The inner fixed end 121 extends into the hollow aluminum plate 11 and is used for fixing and connecting the hollow aluminum plate 11. The outer fixed end 122 is exposed on the hollow aluminum plate. The outside of 11 is used for fixedly connecting the motor case 20 . The motor cover plate 10 is light in weight due to the hollow aluminum plate, and has strong anti-bending ability in cooperation with the support plate 12 extending into the hollow aluminum plate 11 at both ends.

Further, the two sides of the hollow aluminum plate 11 are respectively provided with horizontal J-shaped hooks 111, which are used to increase the strength of the cover plate itself, which is not easy to collapse, and enhances the bending resistance.

As a preferred embodiment, the hollow aluminum plate 11 includes a first hollow cavity 112 , a second hollow cavity 113 disposed on both sides of the first hollow cavity 112 , and a second hollow cavity 113 disposed between the second hollow cavity 113 and the horizontal J-shaped hook 111 . In the third hollow cavity 114 , a first reinforcing rib 115 is disposed between the first hollow cavity 112 and the second hollow cavity 113 , and a second reinforcing rib 116 is disposed between the second hollow cavity 112 and the third hollow cavity 114 . Since the motor cover plate 10 is provided with a plurality of rectangular hollow cavities, and the hollow cavities are supported by reinforcing ribs, the dual effects of light weight and good bending resistance are realized.

As a preferred embodiment, the cross sections of the first hollow cavity 112 and the second hollow cavity 113 are both rectangular, and the cross section of the third hollow cavity 114 is triangular.

As a preferred embodiment, the cross-section of the first hollow cavity 112 is consistent with the cross-sectional shape and size of the inner fixed end 121 of the support plate 12 .

As a preferred embodiment, both ends of the hollow aluminum plate 11 and the inner fixed end 121 of the support plate 12 are provided with several screw holes or rivet holes, and screws or rivets matched with the screw holes or rivet holes.

As a preferred embodiment, the outer fixed end 121 of the support plate 12 is provided with several bolt holes and bolts matched with the bolt holes, and the bolts pass through the bolt holes to fixedly connect the support plate 12 and the motor case 20 .
