DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0023] Please refer to Figures 1 to 8 The embodiment provides a technical solution: a double-stator double-rotor high-power electric tug wheel permanent magnet energy-saving propulsion motor, comprising: a bottom plate 101, the top of the bottom plate 101 is fixedly installed with two vertical plates 114, the opposite side of the two vertical plates 114 is fixedly installed with a motor body 102, one side of one of the vertical plates 114 is fixedly installed with a plurality of springs 117, one end of the plurality of springs 117 is fixedly connected with a vibrating plate 116, one side of the vertical plate 114 close to the plurality of springs 117 is fixedly installed with a plurality of limiting rods 115, the surface of the plurality of limiting rods 115 is movably sleeved with the vibrating plate 116, one side of the vibrating plate 116 is fixedly installed with a linkage block 118, the top of the bottom plate 101 is fixedly installed with an air bag 119, and the linkage block 118 is located on one side of the air bag 119.

[0024] In use, the motor body 102 is fixed above the bottom plate 101, and vibration will be generated when the motor body 102 operates, which will drive the vertical plate 114 to vibrate slightly, and the spring 117 will generate elastic force to make the vibrating plate 116 reciprocate on the outer surface of the limiting rod 115, which will drive the linkage block 118 to move and press the surface of the air bag 119.

[0025] As Figures 1 to 8As shown, in one embodiment, an electric air pump 120 is fixedly installed on the bottom plate 101 near the top of the airbag 119. The electric air pump 120 is fixedly connected to one side of the airbag 119 through an air pipe. An air hole 124 is opened on one side of the airbag 119. A plurality of short rods 121 are fixedly installed on one side of the airbag 119. An air-blocking plug 123 is movably sleeved on the outer surface of the plurality of short rods 121. The air-blocking plug 123 is located inside the air hole 124. A magnet 125 is fixedly installed on the side of the air-blocking plug 123 away from the air hole 124. The electric air pump 120 can inflate the airbag 119 through the pipe. When the airbag 119 is squeezed, the gas comes out through the air hole 124 and pushes the air-blocking plug 123 to slide on the surface of the short rod 121. The pressure of the gas pushed out of the air hole 124 is greater than the repulsive magnetic force between the magnet 125 and the magnet 26, and the gas enters the interior of the thick tube 127.

[0026] like Figures 1 to 8 As shown, in one embodiment, a limiting block 122 is fixedly installed at one end of a plurality of short rods 121. A magnet 126 is fixedly installed on the side of the limiting block 122 near the magnet 125. The magnet 125 and the magnet 126 repel each other.

The gas enters the U-shaped tube 128 through the thick tube 127, and then enters the motor body 102 through the U-shaped tube 128 and then through the air inlet 129. This allows the high-temperature gas inside the motor body 102 to be released through the air outlet 130. As long as the motor body 102 is running, the gas inside the air bag 119 will continuously enter the motor body 102 through the U-shaped tube 128 to dissipate heat from the inside of the motor body 102.

An outer cover 103 is detachably connected to one side of the motor body 102. Multiple fixed blocks 105 are fixedly connected to the outer surface of the outer cover 103. The second movable block 112 fits against the surface of the abutment block 107 to limit the fixing strip 106, thereby installing the outer cover 103. After the outer cover 103 is removed, it is more convenient to repair and inspect the interior of the motor body 102.

A rotating rod 104 is movably embedded inside the outer cover 103. The stop block 109 can move up and down under the limitation of the first movable block 111. At this time, the first movable block 111 and the second movable block 112 are limited. The second movable block 112 fits against the surface of the stop block 107 to limit the fixing strip 106.

By pushing the stop block 109 to move in the vertical groove 110, at this time, the stop block 109 moves upward, the stop block 109 is separated from one side of the first movable block 111, the first movable block 111 and the second movable block 112 move to one side, at this time, the fixed strip 106 is rotated around the rotating rod 113 as the center, at this time, the outer cover 103 can be disassembled, the stop block 109 is located on one side of the first movable block 111, the second movable block 112 can be limited, the second movable block 112 is attached to the surface of the stop block 107, the fixed strip 106 is limited, so that the outer cover 103 is installed, after the outer cover 103 is disassembled, the inside of the motor body 102 can be conveniently maintained and inspected.
