AI Technical Summary
The existing micro motor heat dissipation shell relies on the thermal conductivity of the shell for heat dissipation, resulting in poor heat dissipation effect and the power generated during operation of the micro motor cannot be fully utilized for heat dissipation.
A heat dissipation shell including a circular shell, a heat dissipation plate, a thermal ring, a miniature motor, a shaft, a gear, a fan blade and a bearing were designed. The heat was directed to the surface of the micro motor through the thermal conduction ring, and the heat was directed to the heat dissipation plate and through the gears. In combination with the fan blade, the power of the micro motor drives the fan blade to rotate and enhance the heat dissipation effect.
By increasing the contact area between the micro motor and the external space and using power to drive the fan blades to rotate, the heat dissipation efficiency is significantly improved, and the problem of poor heat dissipation effect caused by relying solely on natural cooling is avoided.

Description
Technical Field
[0001] The present application belongs to the technical field of micro motors, and in particular, relates to a heat dissipation housing for a micro motor. Background Art
[0002] A micro motor is a type of electric motor with a small size and capacity, and an output power generally below a few hundred watts. Although the output power of a micro motor is small, it will still generate a certain amount of heat during operation. In order to ensure that the service life of the micro motor is not reduced due to heat during operation, a corresponding heat dissipation housing is generally used for heat dissipation.
[0003] At present, the existing micro motor heat dissipation housing generally uses its thermal conductivity to transfer the heat inside the micro motor so that the heat dissipates into the air. This heat dissipation rate is too slow and cannot fully utilize the power generated by the micro motor when it is running to dissipate the heat of the micro motor.
[0004] To this end, we propose a heat dissipation housing for a micro motor to solve the above problems. Utility Model Content
[0005] The purpose of the present application is to solve the problem in the prior art that heat is dissipated only by the thermal conductivity of the housing itself, but the heat dissipation effect is poor, and to propose a heat dissipation housing for a micro motor.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A heat dissipation shell for a micro motor comprises a circular shell, the inner wall of the circular shell is fixedly connected with five groups of heat dissipation plates, the inner wall of the circular shell is fixedly connected with a heat conductive ring, the outer surface of the heat conductive ring is fixedly connected with the inner walls of the five groups of heat dissipation plates, the inner wall of the heat conductive ring is fixedly connected with a micro motor, the output end of the micro motor is fixedly connected with a rotating shaft, a first gear is arranged on the outer side of the rotating shaft, a second gear is meshed on the outer surface of the first gear, the inner wall of the second gear is fixedly connected with a rotating shaft, the outer surface of the rotating shaft is fixedly connected with a fan blade, the inner wall of the circular shell is fixedly connected with a bearing, and the inner ring of the bearing is fixedly connected with the outer surface of the rotating shaft.
[0008] Preferably, three groups of slides are fixedly connected to the outer surface of the circular shell, and the inner wall of each group of slides is threadedly connected with two bolts.
[0009] Preferably, two groups of limit blocks are fixedly connected to the outer surface of the rotating shaft, and the bottom surface of each group of limit blocks contacts the outer surface of the micro motor.
[0010] Preferably, two groups of limiting grooves are formed on the upper surface of the first gear, each group of limiting grooves has two limiting grooves, and the interior of each limiting groove is engaged with the outer surface of the limiting block.
[0011] Preferably, two circular clamping holes are provided on the upper surface of each group of the limit blocks, and a circular clamping block is clamped inside each of the circular clamping holes.
[0012] Preferably, the top ends of the two groups of circular blocks are commonly fixedly connected with a baffle, and the bottom surface of the baffle is respectively in contact with the upper surface of the first gear and the upper surfaces of the two groups of limit blocks.
[0013] In summary, the technical effects and advantages of this application are:
[0014] By setting up the mutual cooperation between the heat sink, the heat conductive ring and the micro motor, since the heat conductive ring is in contact with the surface of the micro motor, the heat generated during the operation of the micro motor can be guided to the heat sink, thereby indirectly increasing the contact area between the micro motor and the external space, and then by setting up the mutual cooperation between the first gear, the second gear, the bearing, the fan blade and the rotating shaft, through the meshing connection relationship between the first gear and the second gear, the power generated during the operation of the micro motor can be transmitted to the second gear, thereby driving the fan blade fixed on the outer surface of the rotating shaft to rotate, thereby effectively avoiding the problem that the device can only dissipate heat by natural cooling when in use, and cannot fully utilize the power generated by the operation of the micro motor, resulting in poor heat dissipation effect.

Implementation
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-4 A heat dissipation shell for a micro motor includes a circular shell 1, the inner wall of the circular shell 1 is fixedly connected with five groups of heat dissipation plates 6, the outer surface of the circular shell 1 is fixedly connected with three groups of carriers 9, the inner wall of each group of carriers 9 is threadedly connected with two bolts 10, and by providing the carriers 9 and the bolts 10, the device can be fixed by the carriers 9 and the bolts 10 to ensure that the device can be more stable during operation.
[0022] A heat-conducting ring 8 is fixedly connected to the inner wall of the circular shell 1, and the outer surface of the heat-conducting ring 8 is fixedly connected to the inner walls of the five groups of heat dissipation plates 6. A micro motor 7 is fixedly connected to the inner wall of the heat-conducting ring 8, and a rotating shaft 5 is fixedly connected to the output end of the micro motor 7. Two groups of limit blocks 16 are fixedly connected to the outer surface of the rotating shaft 5, and the bottom surface of each group of limit blocks 16 is in contact with the outer surface of the micro motor 7. By setting the limit blocks 16, the power generated by the micro motor 7 during operation can be transmitted through the limit blocks 16, thereby achieving a better transmission effect.
[0023] A first gear 2 is provided on the outer side of the rotating shaft 5, and two groups of limit grooves 14 are opened on the upper surface of the first gear 2, and the number of limit grooves 14 in each group is two. The interior of each limit groove 14 is snap-connected with the outer surface of the limit block 16. By setting the limit grooves 14, the limit block 16 can be limited by the limit grooves 14, so that the power transmitted by the limit block 16 can be received.
[0024] The outer surface of the first gear 2 is meshed with the second gear 4, the inner wall of the second gear 4 is fixedly connected with the rotating shaft 11, the outer surface of the rotating shaft 11 is fixedly connected with the fan blade 13, and the upper surface of each group of limit blocks 16 is provided with two circular clamping holes 15, and the interior of each circular clamping hole 15 is clamped with a circular clamping block 17. By providing the circular clamping holes 15 and the circular clamping blocks 17, the circular clamping blocks 17 can be clamped in the interior of the circular clamping holes 15, thereby achieving a better clamping effect.
[0025] A bearing 12 is fixedly connected to the inner wall of the circular shell 1, and the inner ring of the bearing 12 is fixedly connected to the outer surface of the rotating shaft 11. The top ends of the two groups of circular clamping blocks 17 are commonly fixedly connected to a baffle 3, and the bottom surfaces of the baffle 3 are respectively in contact with the upper surface of the first gear 2 and the upper surfaces of the two groups of limit blocks 16. By providing the baffle 3, the first gear 2 can be limited by the baffle 3 to ensure that the first gear 2 does not deviate from the range of the rotating shaft 5 during operation.
[0026] The working principle of the utility model is as follows: when in use, the micro motor 7 can be connected to the power supply first, and the device can operate normally after the micro motor 7 is connected to the power supply, and then the device can be fixed as a whole by using the carrier 9 and the bolt 10. The micro motor 7 generates heat when it is running, and the heat enters the inside of the heat sink 6 through the heat conductive ring 8. The heat conductive ring 8 and the heat sink 6 can be made of copper. Because copper has good thermal conductivity, the heat generated by the micro motor 7 when it is running can be evenly dispersed on the heat sink 6 in a very short time. When the micro motor 7 is running, it will drive the rotating shaft 5 to rotate, and when the rotating shaft 5 rotates, it will drive the limit block 16 fixed on the outer surface to rotate inside the limit groove 14. , thereby driving the first gear 2 to rotate. The existence of the limit block 16 and the limit groove 14 can ensure that the first gear 2 can be removed, so as to facilitate replacement. When the first gear 2 is subjected to the rotational power, it will transmit the power to the second gear 4, thereby driving the second gear 4 to rotate. When the second gear 4 rotates, the rotating shaft 11 fixed on the inner wall and the fan blades 13 fixed on the outer surface of the rotating shaft 11 will also rotate, and then the fan blades 13 can draw the outside air into the interior of the circular shell 1. After hitting the bottom surface of the circular shell 1, the wind will diffuse to both sides, and then the heat on the surface of the heat sink 6 can be taken out, thereby effectively avoiding the problem that the device can only dissipate heat naturally when in use, resulting in poor heat dissipation effect.
