[0002] A brushless motor is composed of an electric motor and a driver. It is a typical mechatronic product. A brushless motor refers to a motor without brushes and a commutator, also known as a commutatorless motor. The speed of the brushless motor is controlled by a drive controller.

[0003] After searching, the patent with announcement number CN214626838U discloses a DC brushless motor speed controller, which includes a controller body, a mounting seat is provided at the bottom of the controller body, and a connecting groove is opened at the top of the mounting seat, a connecting plug matching the connecting groove is fixedly connected to the bottom of the controller body, and threaded rods are fixedly connected to the left and right sides of the bottom of the controller body.

[0004] Although the DC brushless motor speed controller mentioned above has the controller body pre-installed to avoid shaking of the controller body and facilitate installation, the controller body and the brushless motor are electrically connected through plug-in wires, and the plug inserted into the connector of the controller body is at risk of accidentally falling off due to external force, causing the controller body to be disconnected from the brushless motor, which is not conducive to maintaining stable use.

[0005] In view of the above problems, the present utility model document proposes a brushless motor drive speed control device. Utility Model Content

[0006] The utility model provides a brushless motor drive speed control device, which solves the problem in the prior art that a controller body and a brushless motor are electrically connected through plug-in wires, and a plug inserted into a connector of the controller body is at risk of accidentally falling off due to external force, causing the controller body to be disconnected from the brushless motor, which is not conducive to maintaining stable use.

[0007] The utility model provides the following technical solutions:

[0008] A brushless motor drive speed control device, comprising:

[0009] A drive controller body, wherein a base is provided below the drive controller body, and two connectors are symmetrically fixedly installed on one side of the drive controller body, wherein a plug is inserted into the connector, and a wire electrically connected to the brushless motor is fixedly provided at the other end of the plug;

[0010] The protection component is arranged on the driving controller body and is used to prevent the plug from being separated from the connector. The protection component includes a protection frame fixedly arranged on one side of the driving controller body, and the two connectors are symmetrically arranged in the protection frame.

[0011] In a possible design, a T-shaped slider is fixedly provided at the center of the bottom of the drive controller body, and a T-shaped slot for slidingly installing the T-shaped slider is provided on the top of the base, and the T-shaped slot is provided through the base.

[0012] In a possible design, mounting plates are symmetrically fixedly provided on both sides of the drive controller body, and the mounting plates are fixed to the base by two fastening bolts.

[0013] In a possible design, two clamping blocks are slidably installed at both ends of the inner wall of the protective frame. The two clamping blocks are arranged opposite to each other in an upper and lower direction. The inner wall of the protective frame is provided with a sliding groove for limiting the horizontal movement of the clamping block, and the clamping block is provided with an arc groove for clamping and fixing the tail of the plug.

[0014] In a possible design, the central threads of the two clamping blocks are connected to the same bidirectional threaded rod, and the two ends of the bidirectional threaded rod are rotatably mounted on the top and bottom of the inner wall of the protective frame. The top of the bidirectional threaded rod passes through the top of the protective frame and is fixed with a hand-tightened cap.

[0015] In one possible design, a ratchet is fixedly mounted on the bidirectional threaded rod, and the ratchet is located between the bottom of the hand-tightening cap and the top of the outer wall of the protective frame. A non-return pawl is rotatably mounted on the top of the outer wall of the protective frame and is used in conjunction with the ratchet, and the non-return pawl is inserted into the tooth groove of the ratchet.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In the present application, when in use, the drive controller body is installed first, and the T-shaped slider at the bottom of the drive controller body is inserted into the T-shaped slot at the top of the base, which also serves the role of pre-installing the drive controller body. Then, the T-shaped slider is slid until the through hole on the mounting plate is aligned with the threaded hole on the top of the base one by one, and then the fastening bolts are used to reinforce it to complete the installation. Then, the plug is inserted into the connector, and the hand screw cap is twisted to drive the bidirectional threaded rod to rotate. Under the limiting action of the slide slot, the two clamping blocks gradually approach, prompting the upper and lower corresponding arc grooves to gradually clamp the tail of the plug, thereby reducing the risk of accidental detachment of the plug due to external force, which is conducive to the stable use of the drive controller body.

[0018] Among them, the rotation of the two-way threaded rod drives the ratchet to rotate at the same time. Under the action of the reset spring, the anti-reverse pawl is continuously stuck in the tooth groove of the ratchet, and with the cooperation of the baffle, the ratchet is prevented from rotating in the opposite direction, thereby preventing the two-way threaded rod from rotating in the opposite direction due to vibration, further improving the clamping effect of the two clamping blocks. When removing the plug, the other end of the anti-reverse pawl is moved to disengage it from the tooth groove of the ratchet, and then the hand-tightening cap is twisted in the opposite direction to make the two clamping blocks move away from each other, and the plug can be pulled out, which is convenient to use.

[0019] The utility model has the following beneficial effects:

[0020] The utility model also plays a role in pre-installing the drive controller body by arranging the T-shaped sliding block and the T-shaped slot, which helps to improve the installation and fixing effect.

[0021] The utility model reduces the risk of accidental detachment of the plug due to external force by arranging a protective component, which is conducive to maintaining stable use of the drive controller body.

[0022] The utility model effectively prevents the bidirectional threaded rod from rotating in the opposite direction due to vibration through the coordinated use of the anti-reverse pawl and the ratchet wheel, thereby further improving the clamping effect of the two clamping blocks.

By inserting the plug 8 into the connector 7, the drive controller body 1 and the brushless motor are connected, so that the speed of the brushless motor is controlled by the drive controller body 1;

[0033] A T-shaped slider 5 is fixedly provided at the center of the bottom of the drive controller body 1, and a T-shaped slot 6 for slidingly installing the T-shaped slider 5 is provided on the top of the base 2. The T-shaped slot 6 is set to penetrate the base 2. The T-shaped slider 5 at the bottom of the drive controller body 1 is inserted into the T-shaped slot 6 at the top of the base 2, which also plays a role in pre-installing the drive controller body 1, which helps to improve the installation and fixing effect.

Then, the T-shaped slider 5 is slid to the through holes on the mounting plate 3 and the threaded holes on the top of the base 2 are aligned one by one, and then the fastening bolts 4 are used to reinforce it to complete the installation;

[0034] A protection component is provided on the drive controller body 1 and is used to prevent the plug 8 from being detached from the connector 7. The protection component includes a protection frame 10 fixedly provided on one side of the drive controller body 1. Two connectors 7 are symmetrically provided in the protection frame 10. Two clamping blocks 12 are slidably installed at both ends of the inner wall of the protection frame 10. The two clamping blocks 12 are arranged opposite to each other up and down. A slide groove 11 for limiting the horizontal movement of the clamping block 12 is provided on the inner wall of the protection frame 10. An arc groove 15 for clamping and fixing the tail of the plug 8 is provided on the clamping block 12.
