[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1-6 As shown together, the multi-axis servo drive module of this embodiment is arranged and installed with the power module and electrically connected through the cooperation of the front end base plate component and the connecting seat component.

[0033] This embodiment includes a drive housing 10 which is open on one side and forms an inner cavity. A drive middle frame 20 is installed at the open portion of the drive housing 10 . It also includes a fan assembly 50 and a battery box assembly 60 which are independently arranged and detachably connected.

[0034] A battery box mounting slot 11 that fits the battery box assembly 60 is formed on the corresponding side of the drive middle frame 20 of the drive housing 10; the drive middle frame 20 extends into the inner cavity of the drive housing 10, and a heat dissipation port 21 is formed on the drive middle frame 20. A drive board 30 and an adapter board 40 that are electrically connected to each other are also configured on one side of the drive middle frame 20.

[0035] Preferably, the drive middle frame 20 includes a partition plate and a bottom plate, which are connected by a mounting buckle 26, wherein the partition plate divides the inner cavity of the drive housing 10 into a heat dissipation duct and a circuit space, and the drive middle frame 20 is provided with a fan assembly slot 22, an adapter board slot 23, a connector slot 24, and a ground terminal slot 25.

[0036] A heat sink 80 is provided in the heat dissipation duct to block the heat dissipation opening 21 .

[0037] The driving board 30 is located on one side of the circuit space and is equipped with a main heating device IPM31 and a temperature sensor 32 for detecting the temperature of the radiator 80 area near the IPM31, and both the IPM31 and the temperature sensor 32 are closely attached to the radiator 80 through the heat dissipation port 21. In this way, the heat of the IPM31 can be conducted to the radiator 80, which facilitates the temperature sensor 32 to detect the temperature of the radiator 80 area near the IPM31. In actual work, a large amount of heat generated by the IPM31 is carried away by the airflow generated by the fan assembly 50 in the heat dissipation duct through the radiator 80. Correspondingly, there is no air flow on one side of the circuit space, the internal environment is clean and tidy, and no dust will enter, ensuring the stable operation of the driving module.

[0038] In addition, an adapter board positioning slot 33 for welding and positioning the adapter board 40 is provided on the driving board 30. Furthermore, the adapter board 40 is arranged in the adapter board slot 23, and the connector 41 on the adapter board 40 is arranged in the connector slot 24, so as to ensure that the tightness of the above structural connection is not affected during the installation and disassembly of this embodiment; it should be noted that the adapter board 40 is vertically fixed and firmly welded by the adapter board positioning slot 33; the connector 41 is used to electrically connect to the power module at the front end. It can be understood that a connector via is provided on the driving middle frame 20 corresponding to the connector 41.

[0039] Similar to the above concept, a fan assembly 50 connected to the drive housing 10 is installed in the fan assembly slot 22, and a grounding terminal 70 is correspondingly installed in the grounding terminal slot 25, ensuring that the tightness of the above structural connection will not be affected during installation and disassembly of this embodiment.

[0040] Since the fan is a wearing part and needs to be maintained or replaced regularly, the fan assembly 50 of this embodiment includes a fan 51 and a fan cover 52 for installing the fan 51, and the fan cover 52 is detachably connected to the fan assembly slot 22; it should be noted that a plug buckle position and a lead slot for the fan 51 are provided on the side of the fan cover 52. After the fan 51 is installed in the fan cover 52, the fan lead is pressed into the lead slot, and then the fan plug is fixed to the plug buckle position, and the whole can be installed in the fan assembly slot 22, which is simple and convenient to operate.

[0041] The battery box assembly 60 includes a battery box 61, a battery 62 installed in the battery box 61, a battery cover 63 fitted at the open end of the battery box 61, and a battery plate 64. The installation relationship formed by the battery box assembly 60 and the battery box mounting slot 11 also conforms to the shape of the drive housing 10, and the space utilization rate is high. When the battery 62 is low on power, the battery box assembly 60 can be easily disassembled to replace the battery, which is convenient and quick.

[0042] In this way, the multi-axis servo drive module disclosed in the utility model effectively reduces the overall volume through a reasonable internal structure layout, and has a good heat dissipation effect and a high protection level; at the same time, an independent battery box assembly and fan assembly design are adopted, and the installation, debugging and maintenance are also extremely simple and convenient; by arranging the adapter plate, connector and its fixing structure at a reasonable position, it can quickly and efficiently be electrically connected to the front-end power module and another independent drive module at the rear end.

[0043] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
