Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a sensored brushless motor. Background Art

[0002] Brushless DC motors use semiconductor switching devices to achieve electronic commutation, that is, electronic switching devices are used to replace traditional contact commutators and brushes; they have the advantages of wide speed regulation, small size, high efficiency and small steady-state speed error. A brushless motor is a brushless motor equipped with a position sensor, and the electronic regulator changes phase through the position sensor signal. At present, the position sensor of most brushless motors is usually built into the motor, specifically, the position sensor is usually built into the PCB board inside the motor or embedded in the iron core. The existing brushless motor has weak waterproof performance, and water stains on the surface of the motor enter the motor through the gap between the housing and the magnetic encoding cover, which can easily cause damage to the PCB board inside the motor; in addition, the existing brushless motor uses fastening bolts to fix the motor body, but after the motor has been working for a long time, the vibration generated by the motor itself will cause the fastening bolts to loosen, which to a certain extent reduces the stability of the motor during operation. Utility Model Content

During installation, the sealing ring 6 is placed in the groove 15 corresponding to the magnetic encoding cover 2, and the size of the sealing ring 6 is larger than the groove 15. Then, the magnetic encoding cover 2 is fixed to the end of the brushless motor body 1 with the help of screws. After installation, the sealing ring 6 will fill the groove 15 of the corresponding shape, thereby completing the sealing of the magnetic encoding cover 2; when the magnetic encoding line 3 is assembled with the magnetic encoding cover 2, glue is used to fill the two groups of grooves 2 7, and then inserted into the groove of the magnetic encoding cover 2. After the glue is cured, a complete seal is formed, thereby achieving waterproofing at the joint of the magnetic encoding cover 2.

[0030] Furthermore, the limiting assembly 11 includes a limiting rod 111 movably connected to the mounting plate 10, and a circular plate 112 is rotatably connected to the rod body of the limiting rod 111. A spring 113 is wound around the rod body of the limiting rod 111, and the spring 113 is connected between the circular plate 112 and the mounting plate 10. A tooth column 114 is fixedly sleeved on the rod body of the limiting rod 111. When installing the brushless motor body 1, first, the limiting rod 111 is pulled upward, and the arranged spring 113 is compressed. The arranged limiting rod 111 drives the mounting block 12 to move upward, so that the through holes on both sides of the mounting platform 8 leak out, and then the two sets of fastening bolts 9 are respectively passed through the through holes on both sides of the mounting platform 8, and the fastening bolts 9 are tightened on the external mounting surface.

[0031] Among them, a pull plate 1 is fixedly connected to the top of the limiting rod 111, and the setting of the pull plate 1 is convenient for pulling the limiting rod 111 to slide.

[0032] Furthermore, the constraint assembly 15 includes a constraint rod 151 slidably arranged on the side wall of the vertical plate 14, the constraint rod 151 is fixedly connected to a second circular plate 152 on the rod body, a second spring 153 is wound around the rod body of the constraint rod 151, and the second spring 153 is connected between the second circular plate 152 and the side wall of the vertical plate 14, and a tooth block 154 that is mutually engaged with the tooth column 114 is fixedly connected to the end of the constraint rod 151. When the constraint rod 151 is pulled, the second spring 153 is compressed, and the constraint rod 151 drives the tooth block 154 to separate from the tooth column 114, so as to release the horizontal limit constraint of the tooth block 154 on the limit rod 111, and then the limit rod 111 is rotated horizontally so that the hexagonal rhombus groove 13 corresponds to the shape of the fastening bolt 9. shaped heads are aligned, and then the limit rod 111 is loosened.

Then the constraint rod 151 is loosened. The constraint rod 151 provided drives the tooth block 154 to be clamped with the tooth column 114 again under the action of the elastic force of the spring 2 153, so as to restore the horizontal limit constraint of the tooth block 154 on the tooth column 114. This device uses the tooth block 154 to limit the tooth column 114 and the limit rod 111 in the horizontal direction, thereby realizing the horizontal limit constraint on the fastening bolt 9. This to a certain extent avoids the situation where the fastening bolt 9 is loosened due to the vibration generated by the brushless motor body 1 itself.

[0033] The end of the restraining rod 151 is fixedly connected with a second pulling plate, and the second pulling plate is provided to facilitate pulling the restraining rod 151 to slide.

[0034] In addition, the sealing ring 6 is made of silicone rubber, which enhances the waterproof performance of the device to a certain extent.

[0035] Working principle: During installation, place the sealing ring 6 into the groove 5 corresponding to the magnetic encoding cover 2, and the size of the sealing ring 6 is larger than the groove 5. Then, the magnetic encoding cover 2 is fixed to the end of the brushless motor body 1 with the help of screws. After installation, the sealing ring 6 will fill the groove 5 of the corresponding shape, thereby completing the sealing of the magnetic encoding cover 2; when the magnetic encoding wire 3 is assembled with the magnetic encoding cover 2, use glue to fill the two groups of grooves 7, and then insert them into the grooves of the magnetic encoding cover 2. After the glue is cured, a complete seal is formed, thereby achieving waterproofing at the joint of the magnetic encoding cover 2;

[0036] When installing the brushless motor body 1, first, pull the limit rod 111 upward, the spring 113 is compressed, and the limit rod 111 drives the mounting block 12 to move upward, so that the through holes on both sides of the mounting platform 8 leak out, and then two sets of fastening bolts 9 are respectively passed through the through holes on both sides of the mounting platform 8, and the fastening bolts 9 are tightened on the external mounting surface;

[0037] Then, the constraint rod 151 is pulled, and the spring 153 is compressed. The constraint rod 151 drives the tooth block 154 to separate from the tooth column 114, so as to release the horizontal limit constraint of the tooth block 154 on the limit rod 111. Then, the limit rod 111 is rotated horizontally so that the hexagonal diamond groove 13 is aligned with the head of the corresponding shape of the fastening bolt 9. Then, the limit rod 111 is loosened. The limit rod 111 drives the hexagonal diamond groove 13 to be clamped on the head of the corresponding shape of the fastening bolt 9 under the action of the elastic force of the spring 113. The constraint rod 151 is then released, and the constraint rod 151 drives the tooth block 154 to re-engage with the tooth column 114 under the action of the elastic force of the spring 153, so as to restore the horizontal limit constraint of the tooth block 154 on the tooth column 114. This device uses the tooth block 154 to limit the tooth column 114 and the limit rod 111 in the horizontal direction, thereby realizing the horizontal limit constraint of the fastening bolt 9. This to a certain extent avoids the situation where the fastening bolt 9 is loosened due to the vibration generated by the brushless motor body 1 itself.
