[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment of a DC brushless motor controller, including a main body 1. The main body 1 is a main component of the DC brushless controller, which can control the rotation of the motor, etc. The front end of the main body 1 is fixedly connected with a fixed column 8. The fixed column 8 can limit the pull rod 5 to rotate only inside the front end of the main body 1. The outside of the fixed column 8 is slidably connected with a pull rod 5. The pull rod 5 can drive the main body 1 to slide out of the installation position for easy maintenance, and the pull rod 5 can release the limit when it slides down, so that the main body 1 can be slid out, so that the DC brushless motor controller can be maintained without repeatedly turning the bolts, which increases the ease of operation. The outside of the pull rod 5 is slidably connected to the front end of the main body 1, and the main body 1 limits the pull rod 5 to rotate only relatively. The side end of the pull rod 5 is slidably connected to the inside of the vertical slot 6. The pull rod 5 can slide down inside the vertical slot 6 to squeeze the conical block 11. The upper end of the pull rod 5 The interior is fixedly connected with a magnet 7, which can be attracted to the front of the main body 1 so that the pull rod 5 remains in a fixed state when not in use, which is convenient for folding. The upper part of the magnet 7 is in contact with the interior of the front end of the main body 1, and the lower part of the pull rod 5 is in contact with a conical block 11. The upper end of the conical block 11 is conical at the side end, and the inclined surface can be squeezed out of the side end of the main body 1 to release the limit. The outside of the conical block 11 is slidably connected to the interior of the front end of the main body 1. The conical block 11 can clamp the main body 1 so that it is fixed relative to the positioning block 4 so that the DC brushless motor controller can remain relatively fixed. The middle interior of the conical block 11 is in contact with the lower part of the fixed column 8. A square groove is provided on the side end of the conical block 11, which can prevent the conical block 11 from being blocked by the fixed column 8 when sliding into the interior of the main body 1. A vertical groove 6 is provided inside the front end of the main body 1, and the vertical groove 6 allows the pull rod 5 to slide down and squeeze the inclined surface of the upper end of the conical block 11.

[0032] Reference Figure 1 、 Figure 2 and Figure 4The front end side of the conical block 11 is fixedly connected with a card block 10, which can limit the conical block 11 from completely sliding out of the front end interior of the positioning block 4. The outside of the card block 10 is slidably connected to the front end interior of the positioning block 4. The positioning block 4 limits the card block 10 and the conical block 11 to only slide horizontally and linearly within a fixed distance. The side end of the conical block 11 is elastically connected to the positioning block 4 through a spring 9. The positioning block 4 can clamp the fixed main body 1 from both ends so that the DC brushless motor controller can be fixed in a predetermined installation position. One end of the spring 9 is fixedly connected to the front end interior of the positioning block 4, and the other end of the spring 9 is fixedly connected to the side of the conical block 11. On the outside of the end, the spring 9 squeezes to keep the conical block 11 fixed inside the front end of the main body 1. The front end of the positioning block 4 is slidably connected to the internal sliding connection of the gear assembly. The upper end of the positioning block 4 is slidably connected to the internal sliding connection of the T-block 3. The T-block 3 can enable the main body 1 to maintain a horizontal position relative to the positioning block 4, which is convenient for installation and positioning. The upper part of the T-block 3 is fixedly connected to the upper parts of both ends of the main body 1, and the main body 1 can keep the T-block 3 relatively fixed. The side end of the positioning block 4 is fixedly connected to the outside with a connecting plate 2. A threaded hole is provided on the connecting plate 2, which can fix the connecting plate 2 in a predetermined installation position, and then the main body 1 is clamped and fixed between the positioning blocks 4.

[0033] Reference Figure 2 and Figure 4 The gear assembly includes a trapezoidal block 12. The side end of the trapezoidal block 12 is an inclined surface that is squeezed by the card block 10 and can slide up to facilitate the conical block 11 to slide into the front end of the positioning block 4 to release the limit. The outside of the trapezoidal block 12 and the outside of the square block 13 are slidably connected to the front end of the positioning block 4. The trapezoidal block 12 and the square block 13 are restricted by the positioning block 4 to only slide vertically within a fixed distance. The lower part of the trapezoidal block 12 contacts the side of the card block 10. The trapezoidal block 12 can block the card block 10 so that it will not slide with the conical block 11, so that The main body 1 after maintenance can be slid back to its original position, which increases the simplicity of installation and fixation. The side end of the trapezoidal block 12 is fixedly connected to the square block 13. The upper end of the trapezoidal block 12 is elastically connected to the upper end of the positioning block 4 through the spring 2 14. The spring 2 14 can keep the trapezoidal block 12 in a sliding state by squeezing. One end of the spring 2 14 is fixedly connected to the upper end of the positioning block 4. The spring 2 14 is squeezed by the positioning block 4 to keep the trapezoidal block 12 relatively fixed. The other end of the spring 2 14 is fixedly connected to the top of the trapezoidal block 12.

[0034] Working principle: The connecting plate 2 is fixed in the predetermined position by bolts, and then the main body 1 can be slid into the middle of the sliding positioning block 4 by sliding, and the T-shaped block 3 slides into the upper end of the positioning block 4. When it slides to the appropriate position, the trapezoidal blocks 12 at both ends can be slid upward, and the trapezoidal blocks 12 and the square blocks 13 are squeezed and slide upward to squeeze the spring 2 14. At this time, the conical blocks 11 at both ends slide into the interior of the two ends of the main body 1 under the squeezing of the spring 1 9 and contact the fixed column 8, so that the main body 1 and the positioning blocks 4 at both ends remain relatively fixed to complete the installation. In this way, the DC brushless motor controller can be fixedly installed. When maintenance is required, the pull rod 5 can be rotated ninety degrees by rotating the pull rod 5, and then the pull rod 5 can be slid down and pulled. The rod 5 slides down and squeezes the upper inclined surface of the conical block 11, causing the conical block 11 to slide a certain distance. Then, pulling it outward can make the pull rod 5 drive the fixed column 8 to slide outward, and the fixed column 8 drives the main body 1 to slide outward. At this time, the inclined surface of the side end of the conical block 11 is squeezed and can slide into the interior of the positioning block 4, and the clamping block 10 squeezes the trapezoidal block 12 to slide up. When the clamping block 10 no longer slides, the trapezoidal block 12 slides down under the squeezing of the spring 14 to keep the clamping block 10 and the conical block 11 fixed. After the maintenance of the DC brushless motor controller is completed, it can be slid back to its original position, and by sliding up the trapezoidal block 12, the clamping block 10 and the conical block 11 slide under the squeezing of the spring 1 9 until the conical block 11 slides into the side end of the main body 1.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
