Description

Technical Field

[0001] This utility model belongs to the field of micro motor technology, and more specifically, it relates to a flat electret micro motor. Background Technology

[0002] Flat electret micromotors employ a top-driven structural design, with their rotors made of electret material. Electret is a specially treated material that can maintain its surface charge for a long time. This characteristic allows flat electret micromotors to generate driving force by utilizing the interaction force between charges during operation. Due to its compact structure, high efficiency, and good stability, it has been widely used in microelectromechanical systems, medical devices, and automated robots.

[0003] In existing flat electret micro motors, the wires are directly soldered to the micro motor during use, and there is no safe disassembly structure. This makes it easy to tear the wires and cause them to separate from the micro motor when disassembling the micro motor during subsequent maintenance. This results in poor stability and low practicality. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] Example 1: This utility model provides a flat electret micro motor, including a micro motor body 1 and a connecting component 2. The connecting component 2 includes a fixing seat 201, a plug-in seat 202, a locking block 203 and an operating block 204. The fixing seat 201 is fixedly installed on the side of the outer shell of the micro motor body 1, and the plug-in seat 202 is inserted into the side of the fixing seat 201. The locking block 203 is inserted laterally into the inside of the plug-in seat 202, and the operating block 204 is inserted longitudinally into the inside of the plug-in seat 202.

[0025] A connecting wire 3 is fixedly installed on the side of the plug-in socket 202, and a conductive pin 2021 is provided on the side of the plug-in socket 202. A conductive connection groove 2011 is provided inside the fixed base 201. The conductive pin 2021 is electrically connected to the connecting wire 3, and the conductive connection groove 2011 is electrically connected to the micro motor body 1. When the conductive pin 2021 is inserted into the conductive connection groove 2011, it can connect to the power supply circuit of the micro motor body 1. When the plug-in socket 202 is inserted into the outside of the fixed base 201, the micro motor body 1, the connecting wire 3 and the power supply equipment can be connected and controlled. The power supply equipment can supply control signals and power to the micro motor body 1 for operation through the connecting wire 3, the conductive pin 2021 and the conductive connection groove 2011, and the operation is stable.

[0026] In this embodiment, the top of the micro motor body 1 is provided with heat dissipation fins 101. The fin design increases the heat dissipation area and improves the heat dissipation efficiency. The heat dissipation fins 101 are connected to the outer shell of the micro motor body 1 by integral molding or welding to ensure good heat conduction.

[0027] In this embodiment, the side of the fixed base 201 is provided with a locking slot 2012, and the inner cross-section of the locking block 203 is a right-angled triangle. When the plug-in base 202 is inserted into the side of the fixed base 201, the locking block 203 is inserted into the locking slot 2012. In use, the connecting component 2 has a quick-release mechanism. The installation operation can be completed by holding the plug-in base 202 and inserting it into the side of the fixed base 201. The plug-in base 202 and the fixed base 201 can be quickly disassembled by pulling the operating block 204 outward. The installation and disassembly are convenient and quick, and the connecting component 2 has a self-locking function. Yes, when the plug-in socket 202 is inserted into the side of the fixed base 201, the operating block 204 can position the locking block 203 under the action of the locking top spring 2042, so that the locking block 203 is inserted into the inside of the locking slot 2012, thereby preventing the plug-in socket 202 from accidentally coming out of the side of the fixed base 201. During the insertion process of the plug-in socket 202, since there is no human intervention in the operating block 204, the locking block 203 can automatically avoid the base body of the fixed base 201 until the locking block 203 is inserted into the inside of the locking slot 2012, making it stable to use.

[0028] In this embodiment, the locking block 203 has an inclined control groove 2031 inside, and the operating block 204 has a control rod 2041 on its outer side. The control rod 2041 is inserted into the control groove 2031. The operating block 204 has a locking top spring 2042 inside, with its two ends abutting against the inside of the operating block 204 and the inside of the insertion / removal seat 202, respectively. In use, when the insertion / removal seat 202 is inserted into the side of the fixing seat 201, and the operating block 204 is pulled outward, since the locking block 203 is inserted into the locking groove 2012, only the operating block 204 is in the locking groove 2012. The internal movement of the plug-in socket 202 independently compresses the locking top spring 2042. When the operating block 204 moves, the control lever 2041 can drive the locking block 203 to move outward through the control groove 2031, thereby releasing the locking relationship between the locking block 203 and the locking groove 2012. Then, by continuing to pull the operating block 204, the plug-in socket 202 can be separated from the fixed seat 201. After separation, the locking block 203 can automatically reset under the action of the locking top spring 2042, so as to provide a locking function when the plug-in socket 202 is inserted into the side of the fixed seat 201 next time. It is flexible and convenient to use.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this invention, after the plug-in socket 202 is inserted into the outside of the fixed base 201, the micro motor body 1, the connecting wire 3, and the power supply device can be connected and controlled. The power supply device can supply control signals and power to the micro motor body 1 for operation through the connecting wire 3, conductive pins 2021, and conductive connection groove 2011. The connecting component 2 has a quick-release mechanism, and the installation operation can be completed by holding the plug-in socket 202 and inserting it into the side of the fixed base 201. The operation can be completed by pulling the operating block 204 outward. The connector 202 enables quick disassembly and assembly between the plug-in base 202 and the fixed base 201, making installation and disassembly convenient and fast. The connecting component 2 also features a self-locking function. When the plug-in base 202 is inserted into the side of the fixed base 201, the operating block 204, under the action of the locking top spring 2042, positions the locking block 203, ensuring that the locking block 203 is inserted into the locking slot 2012. This prevents the plug-in base 202 from accidentally dislodging from the side of the fixed base 201. Furthermore, during the insertion process of the plug-in base 202… Since there is no human intervention in the operating block 204, the locking block 203 can automatically avoid the seat of the fixed base 201 until the locking block 203 is inserted into the locking slot 2012. When the insertion and removal seat 202 is inserted into the side of the fixed base 201, when the operating block 204 is pulled outward, because the locking block 203 is inserted into the locking slot 2012, only the operating block 204 moves alone inside the insertion and removal seat 202 and compresses the locking top spring 2042. When moving, the control lever 2041 can drive the locking block 203 to move outward through the control groove 2031, thereby releasing the locking block 203 from the locking groove 2012. Then, by continuing to pull the operating block 204, the plug-in seat 202 can be separated from the fixed seat 201. After separation, the locking block 203 can automatically reset under the action of the locking top spring 2042, so as to provide a locking function when the plug-in seat 202 is inserted into the side of the fixed seat 201 next time.
