Description

Technical Field

[0001] This utility model relates to the field of motor magnetic ring technology, and in particular to a motor magnetic ring mounting structure. Background Technology

[0002] The rotor of a brushless motor consists of permanent magnets, which are connected to the output shaft along with the housing. The stator is a winding coil. It eliminates the commutator brushes used in brushed motors to alternately change the electromagnetic field. By changing the alternating frequency and waveform of the current wave input to the stator coil of the brushless motor, a magnetic field is formed, which, together with the permanent magnet, causes the magnet to rotate.

[0003] For example, Chinese Patent No. CN219802103U discloses a motor magnetic ring mounting structure, which includes a motor body, a magnetic ring body and a bushing. The bushing is tightly fitted on the output shaft of the motor body. The bushing is made of soft material and is located between the magnetic ring body and the output shaft of the motor body. The bushing and the magnetic ring body are connected by glue.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] In the above-mentioned technical solution, the motor magnetic ring is fixed only by the bushing during the installation process. However, the fixing is not secure during use, which affects the use of the magnetic ring. Utility Model Content

[0006] The purpose of this utility model is to provide a motor magnetic ring mounting structure. First, a magnetic ring bushing is fitted onto the magnetic ring mounting shaft. Then, the motor magnetic ring body is fitted onto the magnetic ring mounting shaft, with the bottom of the motor magnetic ring body inserted into the magnetic ring bushing. While the motor magnetic ring body is fitted onto the magnetic ring mounting shaft, the operating rod pulls the pull rope, which in turn drives the sliding latch to disengage from the corresponding slot. When the slot on the motor magnetic ring body moves to the position of the sliding latch, the operating rod is released, and under the elastic force of the connecting spring, the sliding latch is driven into the corresponding slot, thus achieving the initial positioning of the motor magnetic ring body. Then, another magnetic ring bushing is fitted onto the magnetic ring mounting shaft, with the magnetic ring bushing inserted into the top of the motor magnetic ring body. Finally, by tightening the positioning nut, the magnetic ring mounting shaft can be stably positioned.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A motor magnetic ring mounting structure, comprising:

[0009] The motor shaft has a magnetic ring mounting shaft fixedly connected to its top for mounting the motor magnetic ring body. The magnetic ring mounting shaft is hollow, and a snap-fit ​​assembly for fixing the motor magnetic ring body is installed inside the magnetic ring mounting shaft.

[0010] The aforementioned motor magnetic ring mounting structure includes a snap-fit ​​assembly comprising two snap-fit ​​structures symmetrically arranged on both sides of the magnetic ring mounting shaft. Each snap-fit ​​structure includes a mounting base fixedly connected to the inner wall of the magnetic ring mounting shaft. A sliding latch is slidably connected to the mounting base. A slot matching the sliding latch is formed on the inner wall of the motor magnetic ring body. A positioning ring is fixedly connected to the sliding latch. A connecting spring is installed at a position between the positioning ring and the mounting base.

[0011] In the above-mentioned motor magnetic ring mounting structure, an operating rod for operating the snap-fit ​​assembly is slidably connected to the magnetic ring mounting shaft. Two symmetrically arranged pull ropes are fixedly connected to the bottom of the operating rod, and the other end of the pull ropes is fixedly connected to the side of the sliding snap rod.

[0012] In the above-mentioned motor magnetic ring mounting structure, a guide roller for guiding the pull rope is also installed inside the magnetic ring mounting shaft and at the position corresponding to the pull rope.

[0013] In the above-mentioned motor magnetic ring mounting structure, two magnetic ring bushings for positioning the motor magnetic ring body are installed on the magnetic ring mounting shaft at positions corresponding to the motor magnetic ring body.

[0014] In the above-mentioned motor magnetic ring mounting structure, a positioning nut for fixing the motor magnetic ring body is also installed on the magnetic ring mounting shaft at a position corresponding to the motor magnetic ring body, and an external thread matching the positioning nut is provided on the magnetic ring mounting shaft.

[0015] This utility model has at least the following beneficial effects:

[0016] This invention provides a motor magnetic ring mounting structure. First, a magnetic ring bushing is fitted onto a magnetic ring mounting shaft. Then, the motor magnetic ring body is fitted onto the magnetic ring mounting shaft, with the bottom of the motor magnetic ring body inserted into the magnetic ring bushing. Simultaneously with the motor magnetic ring body fitted onto the magnetic ring mounting shaft, the operating lever pulls the pull rope, causing the sliding latch to disengage from its corresponding slot. When the slot on the motor magnetic ring body moves to the position of the sliding latch, the operating lever is released, allowing the sliding latch to engage with the corresponding slot under the elastic force of the connecting spring, thus achieving initial positioning of the motor magnetic ring body. Next, another magnetic ring bushing is fitted onto the magnetic ring mounting shaft, with the magnetic ring bushing inserted into the top of the motor magnetic ring body. Finally, by tightening the positioning nut, the magnetic ring mounting shaft is securely positioned. Attached Figure Description

[0035] To facilitate the initial positioning of the motor magnetic ring body 3 mounted on the magnetic ring mounting shaft 2, in this embodiment: the snap-fit ​​assembly 203 includes two snap-fit ​​structures 2031 symmetrically arranged on both sides of the magnetic ring mounting shaft 2. Each snap-fit ​​structure 2031 includes a mounting seat 20311 fixedly connected to the inner wall of the magnetic ring mounting shaft 2. A sliding locking rod 20312 is slidably connected to the mounting seat 20311. A slot 204 matching the sliding locking rod 20312 is provided on the inner wall of the motor magnetic ring body 3. A positioning ring 20313 is fixedly connected to the sliding locking rod 20312. The positioning ring 20313 and the mounting seat 20312 are positioned in a slot 204. A connecting spring 20314 is installed between the mounting bases 20311. When the motor magnetic ring body 3 is sleeved on the magnetic ring mounting shaft 2, the operating rod 2034 pulls the pull rope 2032, which in turn drives the sliding locking rod 20312 to disengage from the corresponding locking slot 204. When the locking slot 204 on the motor magnetic ring body 3 moves to the position of the sliding locking rod 20312, the operating rod 2034 is released. Under the elastic force of the connecting spring 20314, the sliding locking rod 20312 is driven into the corresponding locking slot 204, thereby achieving the initial positioning of the motor magnetic ring body 3.

[0036] In order to facilitate the pulling of the sliding lever 20312, in this embodiment: an operating lever 2034 for operating the locking assembly 203 is also slidably connected on the magnetic ring mounting shaft 2. Two symmetrically arranged pull ropes 2032 are fixedly connected to the bottom of the operating lever 2034, and the other end of the pull rope 2032 is fixedly connected to the side of the sliding lever 20312.

[0037] To increase the ease and stability of pulling the sliding lever 20312, in this embodiment, a guide roller 2033 for guiding the pull rope 2032 is also installed inside the magnetic ring mounting shaft 2 at the position corresponding to the pull rope 2032.

[0038] To increase the stability of the motor magnetic ring body 3 mounted on the magnetic ring mounting shaft 2, in this embodiment, two magnetic ring bushings 201 for positioning the motor magnetic ring body 3 are installed on the magnetic ring mounting shaft 2 at positions corresponding to the motor magnetic ring body 3.

[0039] To increase the stability of the motor magnetic ring body 3 mounted on the magnetic ring mounting shaft 2, in this embodiment: a positioning nut 202 for fixing the motor magnetic ring body 3 is also installed on the magnetic ring mounting shaft 2 at the position corresponding to the motor magnetic ring body 3, and an external thread matching the positioning nut 202 is provided on the magnetic ring mounting shaft 2. By tightening the positioning nut 202, and under the action of the external thread, the motor magnetic ring body 3 can be conveniently and stably installed.

[0040] The working principle of this utility model is as follows: First, the magnetic ring bushing 201 is fitted onto the magnetic ring mounting shaft 2. Then, the motor magnetic ring body 3 is fitted onto the magnetic ring mounting shaft 2, with the bottom of the motor magnetic ring body 3 inserted into the magnetic ring bushing 201. Simultaneously with the motor magnetic ring body 3 fitted onto the magnetic ring mounting shaft 2, the operating rod 2034 pulls the pull rope 2032, thereby causing the sliding locking rod 20312 to disengage from the corresponding locking slot 204. Furthermore, when the locking slot 204 on the motor magnetic ring body 3 moves to the sliding... When the movable lever 20312 is in position, the operating lever 2034 is released, so that under the elastic force of the connecting spring 20314, the sliding lever 20312 is driven to engage in the corresponding slot 204, thereby achieving the initial positioning of the motor magnetic ring body 3. Then, another magnetic ring bushing 201 is fitted onto the magnetic ring mounting shaft 2, and the magnetic ring bushing 201 is inserted into the top of the motor magnetic ring body 3. Then, by tightening the positioning nut 202, the magnetic ring mounting shaft 2 can be stably positioned.
