Specific embodiments
[0017] Referring to Figures 1 to 4 As shown, the present utility model provides a DC motor controller, including: a box body 1 and a lid 10. The lower surface of the box body 1 is respectively fixedly connected with a fixing block 14 and a heat dissipation block 15. The bottom of the inner cavity of the box body 1 is fixedly connected with a controller main board 6 through a mounting plate 5. Both ends of the box body 1 are symmetrically provided with heat dissipation ports 4. The inner and outer sides of the heat dissipation ports 4 are respectively fixedly connected with an inner filter plate 7 and an outer filter plate 3 through a fixing frame 8. A sealing sleeve 2 is fixedly connected in the wiring hole opened on the box body 1. At the same time, a sealing groove is opened on the upper surface of the box body 1, and receiving grooves are symmetrically opened on the side surface of the sealing groove. A lead screw 17 is movably connected in the receiving groove through a bearing. The fitting plate 16 is slidably connected in the receiving groove through the lead screw 17 in a screwed manner. The position of the lower surface of the lid 10 corresponding to the sealing groove is correspondingly connected with a fitting ring 9. The upper surface of the lid 10 is symmetrically connected with heat dissipation plates 12. The lower surfaces of the heat dissipation plates 12 are symmetrically connected with heat conduction cylinders 11. The heat conduction cylinders 11 are fixedly connected in the through holes correspondingly opened on the surface of the lid 10. At the same time, a heat dissipation component 13 is fixedly connected in the inner cavity of the heat dissipation plate 12. And a fitting groove is correspondingly opened on the outer side surface of the fitting ring 9 at the position corresponding to the fitting plate 16.
[0018] In this embodiment, the DC motor controller is fixed in a suitable position through bolts and the fixing block 14. During normal use, the external air flow will flow in from the heat dissipation port 4 at one end of the box body 1 and flow out from the heat dissipation port 4 at the other end of the box body 1. During the process of the gas flowing in, it will be subjected to double filtration treatment by the outer filter plate 3 and the inner filter plate 7 in sequence. Thereby, the probability of the dust carried in the air flow flowing into the inside of the box body 1 can be effectively reduced, ensuring that the controller main board 6 inside the box body 1 has a normal heat dissipation effect and reducing the probability of damage to the controller main board 6. At the same time, part of the heat generated inside the DC motor controller will flow out along with the air flow, and the other part of the heat will be respectively transferred into the box body 1 and the lid 10 made of aluminum alloy material. The settings of the heat dissipation block 15, the heat conduction cylinder 11, the heat dissipation plate 12 and the heat dissipation component 13 can effectively increase the heat dissipation area on the outer surfaces of the box body 1 and the lid 10, thereby effectively enhancing the heat dissipation effect on the outer surfaces of the box body 1 and the lid 10. Thereby, the probability of excessive heat accumulation inside the DC motor controller can be further reduced, ensuring the stability of the DC motor controller during operation.
[0019] As a preferred embodiment, four groups of fixing blocks 14 are symmetrically connected to the four corners of the lower surface of the box body 1. The four groups of fixing blocks 14 are all square structures, and mounting holes are provided on the surfaces of the fixing blocks 14. At the same time, the sealing sleeve 2 fixedly connected through the wiring hole on the end face of the box body 1 is a cylindrical structure, and the axial section of the sealing sleeve 2 is an I-shaped structure.
[0020] In this embodiment, as shown in Figure 1 and Figure 2 , the sealing sleeve 2 is made of soft rubber material, so that when the external circuit passes through the wiring hole to connect to the controller main board 6, a good sealing effect can be achieved at the wiring hole. At the same time, the setting of the fixing blocks 14 not only facilitates the installation of the DC motor controller, but also can prevent the lower surface of the box body 1 from fitting the installation surface, increasing the heat dissipation area of the outer surface of the box body 1.
[0021] As a preferred embodiment, a plurality of groups of heat dissipation blocks 15 are fixedly connected to the lower surface of the box body 1 in parallel at equal intervals. The plurality of groups of heat dissipation blocks 15 are all semi-cylindrical structures, and the adjacent heat dissipation blocks 15 on the lower surface of the box body 1 in the width direction are arranged in a staggered manner.

The setting of the heat dissipation blocks 15 can effectively increase the heat dissipation area of the lower surface of the box body 1, thereby assisting in enhancing the heat dissipation effect when the air flow passes through the lower surface of the box body 1.

At the same time, the pore size of the outer filter plate 3 is larger than that of the inner filter plate 7.
[0024] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the setting of the fixing frame 8 enables the inner filter plate 7 and the outer filter plate 3 to be conveniently loaded and unloaded on both sides of the box body 1, thereby reducing the loading and unloading difficulty during the subsequent cleaning of the inner filter plate 7 and the outer filter plate 3. Moreover, the pore sizes of the outer filter plate 3 and the inner filter plate 7 are different, so that the DC motor controller can filter different sizes of foreign matters in the outside world in batches, reducing the probability of blockage of the outer filter plate 3 and the inner filter plate 7, thereby ensuring the smoothness of the heat dissipation openings 4.
[0025] As a preferred embodiment, the sealing groove formed on the upper surface of the box body 1 is in a square-shaped structure. The bottom of the sealing groove is fixedly connected with a square-shaped sealing layer. Both groups of receiving grooves symmetrically formed on both sides of the sealing groove are in a strip-shaped structure. The sizes of the receiving grooves and the fitting plate 16 are adapted to each other. At the same time, the cross-section of the end of the fitting plate 16 away from the lead screw 17 is in an isosceles trapezoid structure.
[0026] In this embodiment, as shown in Figure 1 and Figure 3 , the sealing layer is made of soft rubber material, which can enhance the sealing performance between the sealing groove and the fitting ring 9 when the box body 1 and the box cover 10 are closed, thereby enhancing the sealing performance at the connection between the box body 1 and the box cover 10. At the same time, the structural setting of the fitting plate 16 can assist in reducing the difficulty of the fitting plate 16 being inserted into the corresponding fitting groove, so as to ensure that the box body 1 and the box cover 10 can be fixedly connected smoothly. At the same time, the friction layer fixedly connected in the receiving groove is in a square tube structure, and the inner side surface of the friction layer abuts against the fitting plate 16, so that the problem of accidental rotation of the lead screw 17 without external force can be effectively avoided.
[0027] As a preferred embodiment, a plurality of heat dissipation plates 12 are fixedly connected in parallel at equal intervals along the width direction on the upper surface of the box cover 10. The plurality of heat dissipation plates 12 are all in a square tube structure. The fitting ring 9 fixedly connected to the lower surface of the box cover 10 is in a square-shaped structure. The sizes of the fitting ring 9 and the sealing groove are adapted to each other. At the same time, the mounting plate 5 in the box body 1 is in a grid-shaped structure.
[0028] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the setting of the heat dissipation plates 12 can assist in increasing the heat dissipation area on the upper surface of the box cover 10 and enhancing the heat dissipation effect of the box cover 10. Moreover, the structural setting of the mounting plate 5 can also assist in increasing the contact area between the controller main board 6 and the air flow, thereby assisting in improving the heat dissipation effect of the controller body.
[0029] As a preferred embodiment, a plurality of heat conduction cylinders 11 are fixedly connected in parallel at equal intervals along the length direction on the lower surface of the heat dissipation plates 12. The plurality of heat conduction cylinders 11 are all in a cylindrical structure. The axial cross-section of the heat conduction cylinder 11 is in a U-shaped structure.

At the same time, the heat dissipation component 13 fixedly connected to the inner cavity of the heat dissipation plates 12 is in a grid-shaped structure as a whole, and the heat dissipation component 13 is composed of a positioning plate and heat dissipation rods.
[0030] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the heat dissipation plates 12, the heat conduction cylinders 11 and the heat dissipation component 13 are all made of heat-conducting materials, and then the heat dissipation area of the box cover 10 can be effectively increased, thereby assisting in enhancing the overall heat dissipation effect of the DC motor controller.
