DETAILED DESCRIPTION

[0020] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] like Figures 1 to 3 As shown, a servo motor driver power assembly according to this application includes: a motor 11 driver 12, which drives the motor 11 to operate. The driver 12 includes a housing 121, within which an upper PCB board 122 and a lower PCB board 123 are mounted. The upper PCB board 122 and the lower PCB board 123 can electrically control the motor 11 to control its operation. First, the lower PCB board 123 is fixed to the end of the motor 11 housing, thus fixing the lower PCB board 123 and the motor 11 housing as a whole. Here, a gap is set between the lower PCB board 123 and the end of the housing to ensure that the lower PCB board 123 has heat dissipation space. Then, the upper PCB board 122 is fixed to the lower PCB board 123, thus fixing the upper PCB board 122 and the lower PCB board 123 as a whole. Here, a gap is set between the upper PCB board 122 and the lower PCB board 123 to ensure that there is heat dissipation space between the upper PCB board 122 and the lower PCB board 123. An electrical connector is provided on the housing 121, which is electrically connected to the upper PCB board 122 and the lower PCB board 123. An electrical interface 125 is provided on the outside of the motor 11 housing for connecting the electrical connector, and the electrical interface 125 is electrically connected to the internal circuitry of the motor 11. During installation, the electrical interface 125 is plugged into the electrical connector, and the housing 121 is fixed to the end of the motor 11 to press the upper PCB board 122 and the lower PCB board 123 onto the end of the motor 11, thereby ensuring the stability of the internal structure of the driver 12.

[0022] In this design, the distance from the lower PCB board 123 to the end of the motor 11 housing is greater than the distance from the upper PCB board 122 to the lower PCB board 123. This ensures that there is sufficient heat dissipation space between the motor 11 and the lower PCB board 123, and utilizes the different sizes of heat dissipation spaces to generate air convection, thereby improving heat dissipation performance.

[0023] The servo motor driver 10 described above installs the driver 12 at the tail of the motor 11, and makes the upper PCB board 122 and the lower PCB board 123 fixed with the shell of the motor 11 as a whole, so as to form a module with the motor 11, and integrate the motor 11 and the driver 12, which is compact and firm. The electrical connection is achieved by plugging the electrical interface 125 with the electrical plug, and the overall electrical structure is safe and reliable, and will not be loose due to vibration and other reasons. In addition, the line connection structure is saved, and the structure is simple, universal, low in production cost and high in production efficiency. Such connection structure makes the overall electrical connection structure stable, and the control signal transmission is also more stable, which will not affect the operation of the motor 11.

Through such a wire pressing plate 126 structure, the electrical plug and the electrical interface 125 can be tightly fixed, further improving the stability of the plug-in structure of the electrical plug and the electrical interface 125, and protecting the plug-in part of the electrical plug and the electrical interface 125, improving the stability of the overall structure.

[0025] Specifically, the wire pressing plate 126 is rotatably connected to the plug-in mounting seat 127 provided on the shell 121, and the plug-in mounting seat 127 is formed with a matching surface for matching the wire pressing plate 126. By rotating the wire pressing plate 126 to press the wire pressing plate 126 on the matching surface, part of the electrical interface 125 and the electrical plug can be covered. The plug-in mounting seat 127 is provided with a fixing hole 1271 on one side, and the wire pressing plate 126 is formed with a matching hole for matching the fixing hole 1271. By screwing the wire pressing plate 126 through the fixing hole 1271 and into the matching hole, the wire pressing plate 126 can be fixed to press on the matching surface. Through such an installation structure, the wire pressing plate 126 can be easily opened and fixed, and the wire pressing plate 126 will not be lost when it is removed.

[0026] As a specific embodiment, the lower PCB board 123 is fixed to the shell end of the motor 11 by a plurality of first studs 13, and the upper PCB board 122 is fixed above the lower PCB board 123 by a plurality of second studs 14. Such stud installation structure is not only simple in operation and low in structure cost, but also stable in connection structure

[0027] As a specific embodiment, a heat-conducting pad 15 is arranged above the upper PCB board 122, which is attached to the inner wall of the shell 121 for heat conduction and heat dissipation of the inside of the driver 12

[0028] In the scheme, the upper side of the upper PCB 122 is provided with two heat-conducting pads 15, and the two heat-conducting pads 15 are arranged on the two sides of the upper PCB 122, so as to ensure the uniformity of overall heat dissipation.

[0029] Further, the end of the shell 121 is formed with a plurality of heat dissipation fins 1211 for heat dissipation, so as to improve the heat dissipation performance of the driver 12.

[0030] As a specific embodiment, the center of the lower PCB is provided with a magnetic encoder 124, and the magnetic encoder 124 is connected to one end of the motor shaft of the motor 11, so as to accurately detect the rotation angle of the motor shaft of the motor 11.
