DETAILED DESCRIPTION

[0032] The utility model will be explained in further detail below in combination with the drawings.

[0033] The specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.

[0034] The embodiment relates to an integrated motor driving device, as shown in the figure, comprising a motor body 100, a motor rear cover 200 and a motor controller 300. Figure 1-6

[0035] The motor rear cover 200 is arranged at the rear end of the motor body 100, and the motor rear cover 200 is detachably connected with the motor body 100 through bolts; the motor controller 300 is arranged inside the motor rear cover 200 and located at the rear end of the motor body 100, and the motor rear cover 200 is provided with an interface 210 for connecting the internal motor hole controller; the motor controller 300 is electrically connected with the motor body 100 to realize the control of the program of the motor body 100 and the output of the power supply, and realize good connection effect. The motor rear cover 200 can protect the motor controller 300 inside, avoid the motor controller 300 from being damaged due to impact and collision, and improve the stability of the driving device. Moreover, the motor controller 300 and the motor body 100 are arranged together, connected with the motor rear cover 200 to form an integrated design, improve the overall stability of the device, and can also optimize the overall volume of the device, reduce the space occupation, and make the installation and use more convenient.

[0036] ​At the same time, the connection structure between the motor controller 300 and the motor body 100 is also arranged inside the motor back cover 200, so that the connection structure does not need to be exposed, avoiding being punctured or scratched by foreign objects, and ensuring the operational stability and safety of the device. In this embodiment, the motor controller 300 is electrically connected to the motor body 100 through a plug-in assembly. The motor controller 300 is installed and fixed on the inside of the motor back cover 200. When the motor body 100 is connected to the motor back cover 200, the motor controller 300 can be quickly connected to the motor body through the plug-in assembly, and the connection process is convenient and fast. Specifically, the plug-in assembly includes: a pin 310 arranged on the motor controller 300 and extending to the front end, and a jack 320 arranged at the rear end of the motor body 100 and corresponding to the pin 310. The cooperation between the pin 310 and the jack 320 can achieve a quick connection between the motor controller 300 and the motor body 100, thereby improving the installation and use experience.

[0037] In this embodiment, a heat-insulating material is provided on the inner side of the motor back cover 200, between the motor controller 300 and the motor body 100, so as to reduce the heat generated during the operation of the motor body 100 from being conducted to the motor controller 300, thereby affecting the normal operation of the motor controller 300. The motor body 100 will generate a large amount of heat during operation. If heat insulation treatment is not performed, this heat may be transferred to the motor controller 300, causing the temperature of the motor controller 300 to rise, affecting its performance and life. Therefore, a heat-insulating material is provided between the motor body 100 and the motor controller 300 to reduce heat conduction and ensure that the motor controller 300 can work stably at an appropriate temperature. Preferably, the heat-insulating material is provided as a porous vacuum silicon heat-insulating material, which can achieve a good heat-insulating effect through the characteristics of vacuum and porous silicon. Of course, in other embodiments, other heat-insulating materials can also be selected.

[0038] As a preferred solution, heat dissipation fins 220 are provided extending outward from the rear end of the motor back cover 200 to increase the surface area of ​​the motor back cover 200, that is, to increase the heat dissipation area of ​​the motor back cover 200, which can better dissipate the heat of the motor controller 300 inside the motor back cover 200 and ensure that the motor controller 300 can operate stably at an appropriate temperature.

[0039] In this embodiment, the motor body 100 includes a housing 110, a stator core 120, and a rotating shaft 130 disposed within the stator core 120. The stator core 120 employs a modular structure, comprising a plurality of winding cores 131, which are sequentially connected and arranged in a circular ring around the outer periphery of the rotating shaft 130. Manufacturing flexibility: The modular structure of the stator core 120 enhances flexibility in the production and installation of the stator core 120 and facilitates maintenance. If a winding core 131 is damaged, only the corresponding winding core 131 needs to be replaced, rather than the entire stator core 120, significantly reducing repair costs and time. High material utilization: The modular structure allows for more precise material usage and reduces material waste. As a preferred option, the motor body 100 further includes a servo sensor 140 disposed at the rear end of the motor body 100. Using digital signals to control the motor improves control accuracy, reliability, and flexibility, while reducing maintenance costs and enhancing the system's intelligence.

[0040] Example 2:

[0041] This embodiment relates to an integrated motor driven hydraulic valve, such as Figure 7-8 As shown, it includes: the integrated motor drive device 1000 described in Example 1, a hydraulic valve block 2000 disposed at the front end of the motor body 100, and a valve body 3000 disposed on the hydraulic valve block 2000. By directly placing the hydraulic valve block 2000 at the front end of the motor body 100, the hydraulic valve is miniaturized and the control circuit is exposed to the outside, which can easily be damaged or scratched by external forces during use. This improves the integrity and stability of the hydraulic valve.

[0042] Example 3:

[0043] This embodiment relates to an integrated motor-driven axle, such as Figure 9-10 As shown, it includes: the integrated motor drive device 1000 as described in Example 1, the drive axle 4000, and the reduction gearbox 5000 arranged in the middle of the drive axle 4000. The integrated motor drive device 1000 is arranged on the side of the reduction gearbox 5000 and is connected to the reduction gearbox 5000 for power, so as to realize the power transmission from the integrated motor drive device 1000 to the drive axle 4000 and achieve a good power output effect. This can realize the miniaturization of the drive axle and solve the problem of the control circuit being exposed to the outside and easily damaged and scratched by external forces during use. It can also improve the integrity and stability of the drive axle.

[0044] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
