[0036] In the embodiment of the present application, by arranging the circular heat dissipation ribs 410 in sequence around the heat dissipation end surface 320 of the heat dissipation cover 300, compared with the parallel and spaced straight strip-shaped heat dissipation ribs 440, a larger heat dissipation area can be generated under the condition that the area of the heat dissipation end surface 320, the thickness of the heat dissipation rib 400 and the width of the heat dissipation gap 411 are consistent, which helps to improve the heat dissipation efficiency of the driver 200, so as to facilitate the driver 200 to work in a suitable temperature environment.

[0037] In one embodiment, an integrated drive control machine is provided, please refer to Figures 1-5 The integrated drive control machine includes a motor body 100, a speed reduction wheel 130, a driver 200 and a heat dissipation cover 300.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 The motor body 100 can be arranged in a substantially cylindrical shape, and the side wall of the motor body 100 includes two planar parts and two arcuate parts. The two planar parts are oppositely arranged on the two sides of the motor body 100, and the two arcuate parts are connected between the two planar parts to jointly form the side wall of the motor body 100. Figure 2 For example, as shown in the view angle of

[0039] In one embodiment, the side wall of the motor body 100 can be provided with a mounting block, one side of which is embedded in the motor body 100, and the part of the mounting block outside the motor body 100 can be provided with mounting holes as needed. In addition, a relief groove can also be provided on the side wall of the motor body 100 at the embedding position of the mounting block, so as to mount fasteners such as bolts or other required components into the mounting holes.

[0040] For example, one mounting block is embedded on each of the two arcuate parts, and the mounting blocks are arranged in the middle of the arcuate parts along the length direction of the motor body 100, so that the two mounting blocks are arranged on the left and right sides of the motor body 100. Figure 2The mounting holes can be arranged in parallel along the length direction of the mounting block, and the diameter of the mounting hole in the middle part of the mounting block can be slightly smaller than the diameter of the two mounting holes in the side part of the mounting block. Two avoiding grooves are arranged on the arc surface part at the fitting part of the mounting block, and each avoiding groove corresponds to one mounting hole in the side part of the mounting block.

[0041] It can be understood by those skilled in the art that the number, arrangement position and structure of the mounting block are not limited, and can meet the design and use requirements.

[0042] Please refer to Figures 1-3 , the speed reducer 130 is arranged on one side of the motor body 100. The driver 200 can be arranged on the side of the motor body 100 away from the speed reducer 130, and the driver 200 is integrated with the motor body 100.

[0043] The heat dissipation cover 300 corresponding to the driver 200 is arranged on the same side of the motor body 100, the heat dissipation cover 300 is connected to the motor body 100, and the heat dissipation cover 300 and the motor body 100 form a heat dissipation cavity 310, the driver 200 is accommodated in the heat dissipation cavity 310, and the heat dissipation cover 300 is provided with heat dissipation ribs 400 to dissipate heat of the driver 200, so that the heat generated by the driver 200 during operation can be dissipated in time, which helps to reduce the influence of the heat generated by the motor body 100 during operation on the driver 200.

[0044] In order to improve the heat dissipation efficiency of the driver 200, the arrangement structure of the heat dissipation ribs 400 can be improved to increase the heat dissipation area. In one embodiment, please refer to Figure 2 , the heat dissipation cover 300 has a heat dissipation end face 320 away from the motor body 100, the heat dissipation ribs 400 include a plurality of circular heat dissipation ribs 410, the circular heat dissipation ribs 410 are arranged in sequence on the heat dissipation end face 320, and the heat dissipation gaps 411 are formed between adjacent circular heat dissipation ribs 410.

[0045] The circular heat dissipation ribs 410 are arranged in sequence on the heat dissipation end face 320, compared with the straight strip-shaped heat dissipation ribs 440 arranged in parallel on the heat dissipation end face 320, in the case that the thickness of the heat dissipation ribs 400 and the width of the heat dissipation gaps 411 are consistent, the heat dissipation area is larger, which helps to improve the heat dissipation effect, so that the heat dissipation efficiency of the driver 200 is improved, and the driver 200 can work in a suitable temperature environment.

[0046] Those skilled in the art can understand that the heat dissipation ribs 400 at the center of the heat dissipation end face 320 can be provided in a cylindrical shape, which can set product identification or nameplates and the like on the end face of the cylindrical heat dissipation rib 400 while playing a heat dissipation role. The heat dissipation rib 400 and the heat dissipation cover 300 can be integrally formed of metal or other materials with a relatively high thermal conductivity, so as to ensure the heat conduction efficiency between the heat dissipation cover 300 and the heat dissipation rib 400. In addition, in some embodiments, according to the heat dissipation needs, the peripheral side of the heat dissipation cover 300 can also be arranged with heat dissipation structures such as heat dissipation ribs, heat dissipation fins and the like, so as to improve the heat dissipation effect.

[0047] In an embodiment, please refer to Figure 2 , the edge of the heat dissipation end face 320 is provided with a fixing position, and a fixing piece 321 for fixing the heat dissipation cover 300 is installed on the fixing position. The setting form of the fixing piece 321 is not limited, which can be used to fix the heat dissipation cover 300 on the motor body 100, and exemplarily, the fixing piece 321 can be a bolt, and a screw hole is correspondingly provided on the motor body 100, so that the fixing piece 321 can connect the heat dissipation cover 300 to the motor body 100.

[0048] In order to fully utilize the heat dissipation area of the heat dissipation end face 320 between the fixing pieces 321, in an embodiment, please refer to Figure 2 , the peripheral heat dissipation ribs 420 are arranged along the edge of the heat dissipation end face 320 between adjacent fixing positions, and the two ends of the peripheral heat dissipation rib 420 have a bending part 421, which is connected with the adjacent circular heat dissipation rib 410, so as to avoid the fixing position while fully utilizing the heat dissipation area, and also help to improve the product appearance.

[0049] Please refer to Figure 2 , the peripheral heat dissipation rib 420 and the adjacent circular heat dissipation rib 410 form a circumferentially closed closed cavity 422, and in some embodiments, due to the large occupied area of the fixing piece 321, the thickness of the closed cavity 422 along the radial direction of the circular heat dissipation rib 410 is large, so that the heat dissipation rib 400 can also be added in the closed cavity 422 to further improve the heat dissipation area, and exemplarily, the heat dissipation rib 400 also includes an arc-shaped heat dissipation rib 430, which is arranged in the closed cavity 422, and the arc-shaped heat dissipation rib 430 and the cavity wall of the closed cavity 422 are arranged at intervals.

[0050] In an embodiment, please refer to Figure 1 and 2The heat dissipation cover 300 includes a lead portion 330, and a lead is connected to the lead portion 330 to enable the motor body 100 and the driver 200 to be electrically connected to an external power supply or a control system. The lead portion 330 is protruded on a circumferential side of the heat dissipation cover 300, and an end face of an end of the lead portion 330 away from the motor body 100 can serve as a part of the heat dissipation end face 320. In order to fully utilize the heat dissipation area of the lead portion 330, the heat dissipation ribs 400 further include strip-shaped heat dissipation ribs 440, which are arranged between the peripheral heat dissipation ribs 420 and the arc-shaped heat dissipation ribs 430 of the lead portion 330. A plurality of strip-shaped heat dissipation ribs 440 are arranged in parallel and at intervals, and adjacent strip-shaped heat dissipation ribs 440 and the arc-shaped heat dissipation ribs 430 and the peripheral heat dissipation ribs 420 together form heat dissipation spaces 441.

[0051] Exemplarily, the strip-shaped heat dissipation ribs 440 can be arranged in the protruding direction of the lead portion 330, i.e., arranged in parallel and vertically according to the view angle shown in the drawing. Figure 2 The strip-shaped heat dissipation ribs 440 can also be connected to at least one of the adjacent peripheral heat dissipation ribs 420 and the arc-shaped heat dissipation ribs 430. Since the strip-shaped heat dissipation ribs 440 are arranged between the adjacent peripheral heat dissipation ribs 420 and the arc-shaped heat dissipation ribs 430, the length of the adjacent strip-shaped heat dissipation ribs 440 is different due to the curvature of the arc-shaped heat dissipation ribs 430, and the overall arrangement can be in the form that the strip-shaped heat dissipation ribs 440 in the middle are shorter and the strip-shaped heat dissipation ribs 440 on the two sides are longer.

[0052] Those skilled in the art can understand that the shape, orientation and arrangement of the strip-shaped heat dissipation ribs 440 are not limited, and the heat dissipation area of the heat dissipation end face 320 can be fully utilized.

[0053] In some embodiments, referring to Figure 2 The width of the heat dissipation space 441 can be adapted to the width of the heat dissipation gap 411, i.e., the width of the heat dissipation space 441 can be equal to or close to the width of the heat dissipation gap 411, so that the areas where the strip-shaped heat dissipation ribs 440 and the circular heat dissipation ribs 410 are arranged can be uniformly cooled, which helps to reduce the heat gathering in local areas and improve the heat dissipation quality. Moreover, it helps to avoid forming defects caused by the excessive thickness of the strip-shaped heat dissipation ribs 440 and ensure the forming yield when the heat dissipation cover 300 and the heat dissipation ribs 400 are integrally formed.

[0054] Those skilled in the art can understand that, in order to improve the heat dissipation effect of the driver 200, in addition to improving the heat dissipation efficiency of the heat dissipation cover 300, the heat conduction efficiency of the driver 200 to the heat dissipation cover 300 can also be improved.

[0055] In one embodiment, referring to Figure 3 and Figure 4The driver 200 comprises a plate body 210 and a power element 220 arranged on the plate body 210. The power element 220 can be understood as a component that generates heat during operation, such as a resistor, a diode, etc. The power element 220 can be arranged on the side of the plate body 210 away from the motor body 100, which helps to reduce the influence of the heat generated by the motor body 100 during operation on the performance of the power element 220.

[0056] A heat-conducting layer 500 is arranged between the power element 220 and the cavity wall of the heat dissipation cavity 310. The heat-conducting coefficient of the heat-conducting layer 500 should be at least greater than the heat-conducting coefficient of air, so as to guide the heat generated by the power element 220 to the heat dissipation cover 300. By arranging the heat-conducting layer 500 instead of air for heat conduction, the heat-conducting efficiency is improved, so that the heat generated by the power element 220 during operation can be quickly guided to the heat dissipation cover 300, and then dissipated by the heat dissipation cover 300. The material of the heat-conducting layer 500 can be heat-conducting silicone grease or other materials with high heat-conducting rate.

[0057] In some embodiments, referring to Figure 3 The cavity wall of the heat dissipation cavity 310 opposite to the heat dissipation end face 320 is provided with a protruding portion 340, which abuts against the heat-conducting layer 500, so as to guide the heat generated by the power element 220 to the heat dissipation end face 320 through the cooperation of the heat-conducting layer 500 and the protruding portion 340, and then quickly dissipate by the heat dissipation ribs 400. The arrangement of the protruding portion 340 also helps to reduce the amount of the heat-conducting layer 500, and by reducing the amount of the heat-conducting layer 500 such as heat-conducting silicone grease which has relatively high cost, the product cost is reduced.

[0058] As understood by those skilled in the art, the protruding portion 340 can be integrally arranged with the heat dissipation cover 300 and protrude towards the heat-conducting layer 500 to connect the heat dissipation cover 300 and the heat-conducting layer 500, so as to efficiently guide the heat of the heat-conducting layer 500 to the heat dissipation end face 320.

[0059] In other embodiments, the heat-conducting layer 500 can also be cancelled and only the protruding portion 340 is arranged to directly contact the power element 220 to improve the heat conduction efficiency. However, the arrangement of only the protruding portion 340 has high requirements for manufacturing precision and assembly precision, and the cooperation of the flexible heat-conducting layer 500 not only helps to improve the heat-conducting efficiency, but also helps to reduce the requirements for manufacturing precision and assembly precision and reduce the production difficulty.

[0060] Since the driver 200 and the motor body 100 are integrated, the heat generated by the motor body 100 during operation will directly affect the operation of the driver 200. In order to reduce the influence of the heat generated by the motor body 100 during operation on the driver 200, in one embodiment, referring to Figure 3 and Figure 4The motor body 100 has a mounting surface 110, and the mounting surface 110 is provided with fixing columns 120. The driver 200 is fixed to the fixing columns 120, so that a heat insulation gap 121 is formed between the driver 200 and the mounting surface 110. The heat insulation gap 121 hinders the heat generated by the motor body 100 during operation from being conducted to the driver 200, which helps to reduce the ambient temperature around the driver 200 during operation of the drive control integrated machine, and is conducive to maintaining normal operation of the driver 200.

[0061] Exemplarily, refer to Figure 3 and Figure 4 The end surface of the motor body 100 along the axial direction is used as the mounting surface 110. The mounting surface 110 can be provided with a plurality of fixing columns 120 around the circumference. The end of the fixing column 120 away from the mounting surface 110 can be provided with a threaded hole. The driver 200 can be fixed to the end of the fixing column 120 away from the mounting surface 110 by means of a screw, so that the heat insulation gap 121 is formed between the driver 200 and the mounting surface 110, and the heat generated by the motor body 100 during operation is hindered from being conducted to the driver 200.

[0062] Those skilled in the art can understand that the thickness of the heat insulation gap 121 can be adjusted by changing the axial length of the fixing column 120, so as to adjust the heat insulation effect. Therefore, in different embodiments, the fixing column 120 with a suitable length can be provided according to the design and use requirements. In addition, the fixing column 120 can also be made of a heat insulation material with a low thermal conductivity, so as to increase the thermal resistance of the fixing column 120 and reduce the heat generated by the motor body 100 during operation from being conducted to the driver 200 through the fixing column 120.

[0063] In other embodiments, the fixing column 120 can also be used to fix the driver 200 by means of adhesion, insertion or clamping, or other fixing structures can be used to fix the driver 200. In addition, the heat conducted from the motor body 100 to the driver 200 can also be limited by other means, such as providing a heat insulation material between the driver 200 and the mounting surface 110.

[0064] Since the heat sink 300 is also connected to the motor body 100, the heat generated by the motor body 100 during operation will also be conducted to the heat sink 300, which will affect the dissipation of the heat generated by the heat sink 300 to the driver 200. In this regard, a heat insulation layer such as the heat insulation pad 600 or other forms can be provided at the connection between the heat sink 300 and the motor body 100, so as to hinder the heat generated by the motor body 100 during operation from being conducted to the heat sink 300.

[0065] In one embodiment, refer to Figure 3 and Figure 5The side of the heat dissipation cover 300, which is connected with the motor body 100, has a contact surface. A heat insulation pad 600 can be arranged between the contact surface and the motor body 100 to adjust the heat conduction from the motor body 100 to the heat dissipation cover 300. Those skilled in the art can understand that the shape of the heat insulation pad 600 can be set according to the shape of the contact surface, or can be set as other shapes capable of preventing the contact surface from directly contacting the motor body 100.

[0066] The above application of specific examples to illustrate the present application, is only used to help understand the present application, and is not used to limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
