Detailed Description

The following detailed description of the present invention, taken in conjunction with the accompanying drawings and examples, is provided to enable the invention and its various aspects and advantages to be better understood. However, the specific embodiments and examples described below are for illustrative purposes only and are not limiting of the invention.

The term "connected", as used herein, unless otherwise expressly specified or limited, is to be construed broadly, as meaning either directly or through an intermediate connection. In the description of the present invention, it is to be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", and the like are based on the directions or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, an embodiment of the present invention provides a motor base, which is mainly used for fixing an unmanned motor of a rotor. The motor cabinet includes fixed plate 1 and clamp 2, and the quantity of clamp 2 is two in this embodiment.

The fixing plate 1 is of a plate-shaped structure, a motor fixing hole 11 is formed in the fixing plate 1, and the motor fixing hole 11 is located in the center of the fixing plate 1. Preferably, the number of the motor fixing holes 11 is plural, and in the present embodiment, the number of the motor fixing holes 11 is four. Four motor fixing holes 11 are uniformly distributed along the center of the fixing plate. The motor fixing hole 11 is a through hole, and a screw passes through the motor fixing hole 11 to fix the motor on the fixing plate 1.

The side wall of the fixing plate 1 is provided with heat dissipation fins 12, the heat dissipation fins 12 extend outwards along the horizontal direction, and the plurality of heat dissipation fins 12 are symmetrically arranged on two sides of the fixing plate 1. After the fixed plate 1 is connected with the motor, the radiating fins 12 are positioned right below the motor, and when the motor works and generates heat, the heat of the ore can be radiated through the radiating fins 12. When the motor drives the propeller to rotate, the radiating fins 12 are positioned at the center of the airflow, and the air speed is high, so that the radiating fins 12 can radiate heat.

Two clamps 2 are respectively located at two ends of the fixing plate 1, and the axis A of the clamps is parallel to the lower surface of the fixing plate 1. The clamp 2 is used for being fixedly connected with the cantilever, the cantilever penetrates into the two clamps 2, the clamping screw is installed in the clamping screw hole 21, and after the clamping screw is screwed down, the clamp 2 clamps the cantilever.

Alternatively, the outer edges of the plurality of radiator fins 12 on the same side of the fixing plate 1 are arranged along an arc. The arc line formed by the plurality of heat dissipating fins 12 matches the shape of the housing of the motor so that the heat dissipating fins 12 do not create resistance to the downward airflow.

Optionally, the clamp 2 is provided with a threaded through hole 22, the threaded through hole 22 being perpendicular to the axis a of the clamp.
