Description

Technical Field

[0001] The present invention belongs to the technical field of permanent magnet motors, and specifically relates to a base structure with a movable support frame and a permanent magnet motor. Background Art

[0002] A permanent magnet motor is a motor that places permanent magnets (rare earth) of permanent magnet materials on the rotor poles, and has characteristics such as high power density, high control accuracy, and low noise.

[0003] In the application of the base of a permanent magnet motor, cable management inside the junction box has always been a key issue. Traditionally, multiple cables are often bundled and fixed by cable ties or ropes. Although this method is simple and easy to implement, it is likely to cause the cables to heat up after long-term use, affecting the transmission performance and even posing a safety hazard. In addition, with the continuous development of motor technology, the number and types of cables are also increasing continuously. The traditional cable management method has been difficult to meet the flexibility and efficiency requirements of modern permanent magnet motors for cable management. Moreover, the base materials of conventional motors are all gray cast iron, and the base support plate and base feet of the cast base are cast by fixed molds. At this time, there are the following problems when using a cast base. When there are special requirements for the drilling distance dimension of the base feet holes, drilling may interfere with the support plate, and when the size of the base feet holes is required to be large, the base feet plate of the cast iron base is restricted and cannot meet the requirements, and there may be interference with the support plate of the cast base.

[0043] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1:

[0045] Please refer to Figures 1-11 For this application, a base structure of a movable support frame is provided, including a base 1. Above the base 1, a junction box 3 is installed. Inside the junction box 3, a wire management mechanism 2 is installed. The wire management mechanism 2 includes multiple wire splitting components 21. Among them, each wire splitting component 21 includes two first fixed clamping blocks 211 and two second fixed clamping blocks 212. The two first fixed clamping blocks 211 are symmetrically arranged, and the two second fixed clamping blocks 212 are also symmetrically arranged. A connecting rod 213 is fixedly connected between the first fixed clamping block 211 and the second fixed clamping block 212. A connecting block 214 is fixedly connected to the connecting rod 213. A multi-stage telescopic rod 215 is arranged on the connecting block 214. Here, it should be noted that the number of sections of the multi-stage telescopic rod 215 can be set according to actual needs. An outer sleeve of the multi-stage telescopic rod 215 is provided with a first spring 216, and both ends of the first spring 216 are fixedly connected to the corresponding connecting block 214.

[0046] Specifically, by respectively placing the cables connected to the single root and the permanent magnet motor between the two first fixed clamping blocks 211 and the two second fixed clamping blocks 212, then pushing the connecting block 214 to contract the middle multi-stage telescopic rod 215, and thus the first spring 216 is compressed. When the cable is released, the first fixed clamping block 211 and the second fixed clamping block 212 can be sprung open under the action of the elastic force of the first spring 216. Thus, separating and fixing the multiple cables connected to the permanent magnet motor is realized, changing the original method of bundling multiple cables together with cable ties or ropes, which easily causes the cables to heat up during operation, and even the cables are prone to interfere with each other, thereby affecting the transmission performance.

[0047] Embodiment 2:

[0048] On the basis of Embodiment 1, an assembly component 22 is installed on the wire splitting component 21. The assembly component 22 includes two symmetrically arranged assembly blocks 222. On both sides of the connecting block 214, first sliding grooves 2142 for the assembly blocks 222 to slide are respectively arranged. Inside the first sliding grooves 2142, a second spring 221 is also installed to reset the assembly blocks 222. One end of the second spring 221 is fixedly connected to the assembly block 222, and the other end of the assembly block 222 is fixedly connected to the inner wall of the first sliding groove 2142.

[0049] In this embodiment, two fixing seats 4 are fixedly connected inside the junction box 3. Each fixing seat 4 is provided with a second chute 41 for the sliding of the assembly block 222. The fixing seat 4 is further provided with an extension block 42. The extension block 42 provides support for the assembly block 222, and the inclined surface of the assembly block 222 cannot contact the extension block 42 to prevent the assembly block 222 from being squeezed and retracted into the inside of the first chute 2142. The fixing seat 4 includes a vertex angle 43. The inclined direction of the vertex angle 43 is opposite to the inclined direction of the assembly block 222, which enables the assembly block 222 to contact the vertex angle 43 through the inclined surface and then be squeezed into the inside of the second chute 41. The purpose of setting the extension block 42 is to prevent the further sliding of the assembly block 222.

[0050] Specifically, by pressing a single connection block 214 between the two fixing seats 4, the inclined surface on the assembly block 222 first contacts the vertex angle 43. The assembly block 222 is forced to slide into the inside of the first chute 2142 until the inclined surface of the assembly block 222 disengages from the vertex angle 43. The assembly block 222 can be clamped into the inside of the second chute 41 under the action of the elastic force of the second spring 221, completing the rapid splicing. Thus, it is possible to install the corresponding number of wire management mechanisms 2 according to the actual number of cables of the permanent magnet motor, so as to avoid the problem that the number of groups of the wire management mechanism 2 is more than the number of cables, resulting in waste of resources, or the number of groups of the wire management mechanism 2 is too small, leading to the inability to fix all the cables. Through this method, its flexibility is higher.

[0051] Embodiment Three:

[0052] On the basis of Embodiment Two, a push clip mechanism 5 is further installed on the junction box 3. The push clip mechanism 5 includes a driving component 51. Among them, the driving component 51 includes a driving rod 511 rotatably connected inside the junction box 3 and arranged between the two fixing seats 4. A lead screw 512 is fixedly connected to the driving rod 511. A push block 513 for pushing the nearest connection block 214 to move is threadedly connected to the lead screw 512. The fixing seat 4 is provided with a third chute 44 for the sliding of the push block 513 to prevent the push block 513 from rotating with the lead screw 512. A guiding groove 2141 matching the push block 513 is provided on the side of the connection block 214 close to the push block 513.

[0053] Specifically, the rotation of the driving rod 511 drives the rotation of the lead screw 512. The rotation of the lead screw 512 drives the push block 513 to slide along the third chute 44. The push block 513 first pushes the nearest wire management mechanism 2 to clamp and fix the cable. Then, the connection block 214 in the first group of wire management mechanisms 2 continues to push the connection block 214 in the second group of wire management mechanisms 2, and so on, realizing that multiple groups of wire management mechanisms 2 clamp the cables in the middle of them without operating one by one, saving time and labor.

[0054] Embodiment 4:

[0055] On the basis of the third embodiment, the push-clamp mechanism 5 also includes an anti-loosening component 52, which includes a disc 526 fixedly connected to the outer wall of the junction box 3 and a sleeve 521 sleeved on the outside of the driving rod 511, a limit strip 522 is arranged inside the sleeve 521, and a No. 4 slide groove 5111 is arranged on the driving rod 511 for sliding, so as to prevent the driving rod 511 from rotating along with the screw rod 512 during rotation, a No. 3 spring 523 is arranged inside the sleeve 521, one end of the No. 3 spring 523 is fixedly connected to the sleeve 521, and the other end of the No. 3 spring 523 is fixedly connected to the driving rod 511, and a driving block 524 is arranged on the end of the sleeve 521 away from the driving rod 511, an L-shaped plug rod 525 is fixedly connected to the driving block 524, and a slot 527 arranged in a ring array and adapted to the L-shaped plug rod 525 is arranged on the disc 526.

[0056] Specifically, pulling the drive block 524 drives the L-shaped rod 525 to separate from one of the slots 527 of the disc 526. During this process, the No. 3 spring 523 is stretched, and the sleeve 521 slides outward relative to the drive rod 511. Then, by rotating the drive block 524, the sleeve 521 and the drive rod 511 are driven to rotate, and then the drive assembly 51 drives the multiple groups of cable management mechanisms 2 to clamp and fix the cables. When the cables are fixed, the force applied to the drive block 524 can be reduced to make the L-shaped rod 525 re-inserted into the inner part of the nearest L-shaped rod 525, and under the pulling force of the No. 3 spring 523, it cannot be separated from the slot 527, and the limiting is completed. At this point, the cooperation between the L-shaped rod 525 and the slot 527 can avoid the problem of rotation of the screw rod 512 on the drive rod 511, thereby solving the problem that the vibration generated during the use of the permanent magnet motor affects the easy relaxation of the No. 1 fixing clamp 211 and the No. 2 fixing clamp 212 that clamp the cables.

[0057] Embodiment five:

[0058] On the basis of Embodiment 4, an adjustment mechanism 6 is installed on the base 1. The adjustment mechanism 6 includes multiple support plates 61 welded to the base 1. A slider 62 is arranged on the support plate 61, and a floor plate 63 is arranged below the support plate 61. A fifth chute 631 is arranged on the floor plate 63. The slider 62 is slidably connected inside the fifth chute 631, and an installation hole 632 for installation and fixation is also arranged on the floor plate 63. The design of the movable support plate 61 allows the position and spacing of the floor holes to be adjusted according to actual needs. The support plate 61 and the floor plate 63 can move relative to each other, avoiding the problem of interference between punching and the support plate 61. At the same time, it also ensures that even when the size requirement of the floor hole is large, it can be easily met without worrying about conflicts with the base support plate 61, greatly enhancing the adaptability of the base to different installation requirements.

[0059] In this embodiment, an end cover 8 is arranged on the base 1. The base 1 and the end cover 8 can be fixed by bolts 9 for installing the permanent magnet motor inside the base 1.

[0060] This embodiment also discloses a permanent magnet motor, including a base structure with a movable support frame.

[0061] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it.
