DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a model aircraft motor that is easy to dissipate heat, including a base 1, a casing 2 is fixedly installed on the base 1, a driving unit 3 is fixedly installed inside the casing 2, a motor 4 is fixedly installed on the outer wall of the casing 2, a rotating rod 5 is fixedly connected to the output end of the motor 4, and a fan blade 6 is fixedly installed on the end of the rotating rod 5. The fan blade 6 at the end of the rotating rod 5 is driven by starting the motor 4 to rotate to dissipate heat inside the casing 2, a heat dissipation mechanism 7 is arranged on the casing 2, and a transmission mechanism 8 is arranged inside the casing 2.

[0022] In this embodiment, a heat dissipation mechanism 7 is provided on the casing 2. Through the setting of the heat conduction plate 72 in the heat dissipation mechanism 7, the heat inside the casing 2 can be quickly conducted to the outside to cool the inside. At the same time, the fan blades 6 at the end of the rotating rod 5 are rotated to blow air to the inside of the casing 2, and the internal heat flow is guided to the heat conduction plate 72 for rapid cooling.

[0023] In this embodiment, a transmission mechanism 8 is provided inside the casing 2. The eccentric wheel 87 in the transmission mechanism 8 continuously squeezes the bottom end of the upper squeezing rod 82, so that the slider 84 can drive the sleeve plate 86 on the side wall to move left and right to squeeze the vertical rod 74 passing through the inside. The left and right swing of the heat conducting plate 72 can make the contact surface between the outer wall and the external air wider, so that the heat dissipation effect of the heat conducting plate 72 is better, thereby accelerating the heat dissipation inside the casing 2.

[0024] The above-mentioned heat dissipation mechanism 7 includes a round rod 71, which is rotatably connected to the inner wall of the casing 2. A vertical rod 74 is fixedly installed on the outer wall of the round rod 71, and a heat conducting plate 72 is fixedly installed on the outer wall of the round rod 71. The heat conducting plate 72 arranged on the casing 2 can quickly conduct the heat inside the casing 2 to the outside to cool the inside. The outer wall of the round rod 71 is fixedly connected to one end of a torsion spring 73, and the other end of the torsion spring 73 is fixedly connected to the inner wall of the casing 2.

[0025] The transmission mechanism 8 includes a fixed plate 81, which is fixedly mounted on the inner wall of the casing 2. An extrusion rod 82 is penetrated inside the fixed plate 81, and a return spring 83 is sleeved on the outer wall of the extrusion rod 82. One end of the return spring 83 is fixedly connected to the outer wall of the extrusion rod 82, and the other end of the return spring 83 is fixedly connected to the outer wall of the fixed plate 81. The extrusion rod 82 can be moved downward and reset by the elastic force of the return spring 83. A slider 84 is slidably connected to the inner wall of the casing 2. The slider 84 is hinged to one end of a support rod 85, and the other end of the support rod 85 is hinged to the end of the extrusion rod 82. The rod 82 continuously moves upward to squeeze the end of the support rod 85, so that the slider 84 can continuously move to the right. A sleeve plate 86 is fixedly installed on the side wall of the slider 84, and the vertical rod 74 passes through the interior of the sleeve plate 86. The sleeve plate 86 on the side wall is driven by the slider 84 to move left and right to continuously squeeze the vertical rod 74 passing through the interior, so that the vertical rod 74 can drive the round rod 71 on the outer wall to rotate. An eccentric wheel 87 is fixed on the outer wall of the rotating rod 5. The eccentric wheel 87 is located at the bottom of the extrusion rod 82. When the eccentric wheel 87 rotates, it squeezes the bottom end of the upper extrusion rod 82, so that the eccentric wheel 87 can move upward.

[0026] In this embodiment, the fan blade 6 at the end of the rotating rod 5 is driven by the starting motor 4 to rotate to dissipate heat inside the casing 2. At the same time, the heat inside the casing 2 is quickly guided to the outside through the heat conducting plate 72 provided on the casing 2 to cool the inside. The eccentric wheel 87 on the outer wall is driven to rotate by the rotating rod 5. When the eccentric wheel 87 rotates, it squeezes the bottom end of the upper extrusion rod 82, and then the elastic force of the reset spring 83 causes the extrusion rod 82 to move downward and reset, thereby causing the extrusion rod 82 to continuously move upward to squeeze the end of the support rod 85. The slider 84 is then hinged with the support rod 85 to move the slider 84 to the right, and the slider 84 drives the sleeve 86 on the side wall to move left and right. When the sleeve 86 moves left and right, it continuously squeezes the vertical rod 74 penetrating the inside, so that the vertical rod 74 drives the round rod 71 on the outer wall to rotate, and the round rod 71 drives the heat conducting plate 72 to swing left and right, and then the outer wall of the heat conducting plate 72 moves to a wider contact surface with the external air, so that the heat dissipation effect of the heat conducting plate 72 is better, and the heat dissipation inside the casing 2 is accelerated.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
