[0028] The utility model provides a driving device, including a motor 11 and a heat dissipation device 12 connected to the motor 11 for dissipating heat from the motor 11. The motor 11 includes a rotor 112 and an upper cover 111 and a lower cover 113 respectively connected to both ends of the rotor 112. The output shaft 1121 of the rotor 112 passes through the lower cover 113. The lower cover 113 is provided with a plurality of air inlets 1131. The heat dissipation device 12 includes a fixing plate 121, a connecting pipe 122 located on the fixing plate 121 and used for connecting the output shaft 1121. , and a plurality of fan blades 123 located on the fixing plate 121 and on the peripheral side of the connecting tube 122, the plurality of fan blades 123 are centered on the connecting tube 122 and extend to the outside of the fixing plate 121, and an air duct 125 is formed between adjacent fan blades 123, the motor 11 is used to provide a driving source for the electronic product, the heat sink 12 is used to dissipate heat for the motor 11, when the connecting tube 122 is used to be connected to the output shaft 1121 of the rotor 112, the fixing plate 121 is used to install the fan blades 123 and the connecting tube 122, the fan blades 123 is used to guide air into the air duct 125 to form an air flow and blow it out to the downwind air inlet 1131, so as to dissipate heat for the rotor 112. The fixing plate 121 is fixed to the output shaft 1121 of the rotor 112 through the connecting pipe 122. When the motor 11 rotates, the output shaft 1121 of the rotor 112 drives the connecting pipe 122 to rotate, and the connecting pipe 122 drives the fixing plate 121 to rotate. Since the fan blade 123 is connected to the fixing plate 121, and the fan blade 123 is connected to the connecting pipe 122, the fan blade 123 is connected to the fixing plate 121. 22 is the center and extends to the outside of the fixed plate 121. When the fixed plate 121 rotates, an air duct 125 is formed between adjacent fan blades 123. The air duct 125 gathers the air to form an airflow in the direction of the connecting pipe 122 and blows it into the rotor 112 from the air inlet 1131 of the lower cover 113 for heat dissipation. Not only is the structure simple, but the installation is also relatively convenient. The heat dissipation device 12 does not need to be connected to other driving sources. The heat dissipation device 12 rotates with the output shaft 1121, which can effectively accelerate the heat dissipation of the motor 11.

[0029] The fan blades 123 are arranged in an arc shape. When rotating, the fan blades 123 can effectively guide the air to the air duct 125, thereby increasing the airflow blowing into the rotor 112 to dissipate the heat of the rotor 112, and the heat dissipation effect is better.

[0030] The heat dissipation device 12 further includes a transmission tube 124 connected to the fixing plate 121 . The transmission tube 124 and the connecting tube 122 are respectively located on two sides of the fixing plate 121 . The transmission tube 124 is used to facilitate connecting the driving device to the electronic device.

[0031] The outer side of the lower cover 113 is a concave structure toward the direction of the rotor 112. The first end of the fan blade 123 close to the connecting tube 122 is higher than the second end of the fan blade 123. When the fixing plate 121 is connected to the concave lower cover 113, the volume of the driving device can be reduced. The first end of the fan blade 123 is higher than the second end of the fan blade 123 to prevent the fan blade 123 from contacting the lower cover 113 during rotation.

[0032] The fixing plate 121, the connecting tube 122, the transmission tube 124, and the fan blade 123 are an integrally formed structure. The integrally formed fixing plate 121, the connecting tube 122, the transmission tube 124, and the fan blade 123 are more solid and are not easy to break.

[0033] Please refer to Figure 4 , Figure 4 This is a three-dimensional diagram of the lower cover of the driving device of the utility model. The lower cover 113 is also provided with a plurality of fixing columns 1132 extending toward the upper cover 111 and used to be connected to the upper cover 111. The fixing columns 1132 are used to be connected to the upper cover 111 to clamp the rotor 112 between the upper cover 111 and the lower cover 113. The upper cover 111 and the lower cover 113 are used to facilitate fixing the rotor 112 on the electronic device.

[0034] Please refer to Figure 5 , Figure 5 This is a three-dimensional diagram of the upper cover of the driving device of the utility model. The upper cover 111 is provided with an arc-shaped positioning plate 1111 for positioning the fixing column 1132. The positioning plate 1111 is used to position the fixing column 1132. When the upper cover 111 and the lower cover 113 are fixed, the upper cover 111 and the lower cover 113 are prevented from moving, and the installation is more convenient.

[0035] The output shaft 1121 is interference-connected with the connecting pipe 122 , which facilitates installation and disassembly of the heat dissipation device 12 .

[0036] Working principle:

[0037] During installation, first, the connecting tube 122 on the fixing plate 121 is installed on the output shaft 1121. The output shaft 1121 is interference-connected in the connecting tube 122, which can effectively prevent the connecting tube 122 from idling on the output shaft 1121. Since the lower cover 113 is concave, a part of the fan blade 123 extends into the lower cover 113, and the first end of the fan blade 123 close to the connecting tube 122 is higher than the second end of the fan blade 123. When the fan blade 123 rotates, it can prevent the fan blade 123 from contacting the side wall of the lower cover 113. Furthermore, when the rotor 112 rotates, the output shaft 112 of the rotor 112 121 rotates and drives the fixed plate 121 to rotate. When the fixed plate 121 rotates, the fan blades 123 rotate along with the fixed plate 121. When the fan blades 123 rotate, air enters between adjacent fan blades 123 and forms airflow, which enters the rotor 112 from the air inlet 1131 of the lower cover 113, thereby dissipating the heat of the rotor 112. At the same time, since the fan blades 123 are arranged in an arc shape, the arc-shaped fan blades 123 can effectively guide the air to enter the air duct 125, thereby increasing the air intake and achieving a better heat dissipation effect on the rotor 112. Not only is the structure simple, but the installation and disassembly methods are also more convenient.

[0038] When the driving device of this preferred embodiment is connected to the output shaft through the connecting pipe, when the rotor rotates, it drives the fixed plate to rotate. When the fixed plate rotates, the fan blades follow the fixed plate to rotate. When the fan blades rotate, air enters from the air ducts between adjacent fan blades and forms an airflow to be blown into the air inlet of the lower cover, thereby dissipating the heat of the rotor. The heat dissipation device does not need to be connected to other driving sources. It is not only simple in structure, but also simple in installation and disassembly. At the same time, it can also effectively reduce the size of the driving device.

[0039] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
