Description
Technical Field
[0001] The utility model relates to the technical field of generator stator bases, in particular to a generator stator base connection structure. Background Art
[0002] A generator is a device that converts mechanical energy into electrical energy. The stator base is an important component of the generator structure. It usually refers to the frame or platform that supports the generator stator. The stator is the fixed part of the generator. It generates a magnetic field through the flow of current, providing solid physical support for the stator and ensuring the overall stability and safety of the generator.
[0003] Patent document CN217010451U, a publication numbered CN217010451U, discloses a motor stator core comprising six metal limit bars arranged at equal angles within the stator core shell, with stator teeth mounted on the inner sides of the metal limit bars; a retaining ring arranged inwardly of the stator teeth, with tooth blocks fixed at equal angles on the outer side of the retaining ring, and symmetrical retaining grooves formed on the left and right side walls of the retaining ring. This motor stator core utilizes a novel structural design, enabling the stator core to be assembled using an assembled structure, controlling the interference fit of multiple stator teeth between the stator core shell and the retaining ring. This assembled structure reduces material waste during stamping and cutting of the stator core. Furthermore, if problems arise with the stator core over extended use, only the stator teeth need to be replaced, reducing subsequent motor equipment maintenance costs.
[0004] The above-mentioned and existing technologies have the following defects: the electronic base of the generator is usually connected by a snap-on method, which is achieved by inserting a rectangular bar into a rectangular slot. Although this connection method is convenient, when assembling the generator, the rectangular bar can easily fall out of the rectangular slot, causing the stator core shell to be knocked and hit. The impact can easily cause damage to the stator core shell, thereby affecting the performance and safety of the generator.
[0005] Therefore, a generator stator base connection structure is proposed. Utility Model Content

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0033] like Figure 1 - Figure 5 As shown, the utility model provides a generator stator base connection structure, including a generator housing 1 and a stator core shell 2, the stator core shell 2 is located in the generator housing 1, and a plurality of rectangular bars 3 are fixedly connected to the inner wall of the generator housing 1, and a plurality of rectangular grooves 4 are opened on the arc surface of the stator core shell 2. A fixing ring 6 is installed on the inner wall of the stator core shell 2, and a limiting structure 5 is provided on the surface of the generator housing 1. By setting the limiting structure 5, it is convenient to limit the rectangular bars 3 that slide into the rectangular grooves 4, thereby avoiding the collision caused by the rectangular bars 3 sliding out of the rectangular grooves 4 when assembling the generator, thereby ensuring the performance and safety of the generator.
[0034] The specific setting and function of the limiting structure 5 will be described in detail below.
[0035] like Figure 3 - Figure 7As shown, the limiting structure 5 includes a plurality of threaded rods 501, each of which is threadedly inserted into the surface of the generator housing 1. The threaded rods 501 thread through the rectangular bar 3. The end of the threaded rod 501 near the stator core shell 2 is rotatably connected to an elliptical block 502. The surface of the rectangular bar 3 is provided with a groove 503, and the size of the elliptical block 502 matches the size of the groove 503. The inner wall of the rectangular slot 4 is provided with an elliptical groove 504, and the size of the elliptical groove 504 matches the size of the groove 503. The end of the threaded rod 501 away from the elliptical block 502 is fixedly connected to a circular plate 505. Two mounting plates 506 are fixedly connected to one end of the rectangular bar 3. When the stator core shell 2 moves, the mounting plates 506 first slide into the rectangular slot 4. As the stator core shell 2 moves, the mounting plates 506 are squeezed, causing the mounting plates 506 to tilt. When the two mounting plates 506 are fixed at one end of the rectangular bar 3, they are tilted, further facilitating the sliding of the rectangular bar 3 into the rectangular slot 4. Two elastic plates 507 are fixedly connected to one end of the two mounting plates 506 that are close to each other. The elastic plates 507 are made of rubber. When the mounting plates 506 tilt, they squeeze the elastic plates 507. The elastic plates 507 support the tilt of the mounting plates 506, thereby preventing the mounting plates 506 from being damaged and unable to be reset due to excessive pressure. A plurality of protrusions 508 are fixedly connected to one side of the rectangular bar 3. The cross-section of the protrusions 508 is arc-shaped. When the rectangular bar 3 slides in the rectangular groove 4, the rectangular bar 3 drives the protrusions 508 to slide along the inner wall of the rectangular groove 4, thereby reducing the friction force of the rectangular bar 3 when moving in the rectangular groove 4, thereby facilitating the movement of the stator core shell 2. A plurality of arc-shaped blocks 509 are fixedly connected to the arc surface of the circular plate 505. The arc-shaped blocks 509 on the surface of the circular plate 505 prevent the hand from slipping when rotating the circular plate 505, thereby facilitating the rotation of the circular plate 505. The circular plate 505 has a plurality of circular grooves 510 formed on its arcuate surface. A plurality of fixed plates 511 are fixedly connected to the surface of the generator housing 1. A latch 512 is slidably inserted through the surface of the fixed plate 511. The size of the latch 512 matches the size of the circular groove 510. Once inserted into the circular groove 510, the latch 512 serves to restrict the rotation of the circular plate 505, thereby further enhancing the stability of the elliptical block 502 in retaining the position of the stator core housing 2. A spring 513 is sleeved on the arcuate surface of the latch 512. The ends of the spring 513 are fixedly connected to the fixed plate 511 and the latch 512, respectively. The latch 512 is inserted into the circular groove 510 by the contraction force of the spring 513. The spring 513 serves to restrict the position of the latch 512, thereby preventing the latch 512 from being dislodged from the circular groove 510 due to shaking.
[0036] The overall working principle is that when the stator base needs to be connected to the generator, the stator core shell 2 is first placed on one side of the generator housing 1, and then the stator core shell 2 is pushed. The stator core shell 2 moves and gradually slides into the generator housing 1. The movement of the stator core shell 2 first causes the mounting plate 506 to slide into the rectangular groove 4. While moving, the mounting plate 506 is squeezed, causing the mounting plate 506 to tilt and then squeeze the elastic plate 507. When the stator core shell 2 moves to a suitable position, the rectangular bar 3 slides into the rectangular groove 4. When the rectangular bar 3 slides in the rectangular groove 4, the rectangular bar 3 drives the protrusion 508 along the rectangular groove 4. The inner wall slides, thereby reducing the friction when the rectangular bar 3 moves in the rectangular groove 4, thereby facilitating the movement of the stator core shell 2. The two mounting plates 506 are in an inclined state when one end of the rectangular bar 3 is fixed, thereby further facilitating the rectangular bar 3 to slide into the rectangular groove 4. The elastic plate 507 supports the inclination of the mounting plate 506, thereby preventing the mounting plate 506 from being damaged and unable to be reset due to excessive pressure. When the rectangular bar 3 completely slides into the rectangular groove 4, the latch 512 is pulled, and the latch 512 moves to slide in the fixed plate 511 and gradually disengage from the circular groove 510. When the latch 512 moves, the spring 51 3 is stretched. When the latch 512 is disengaged from the circular groove 510, the spring 513 is in a stretched state. Then the circular plate 505 is rotated. The arc block 509 on the surface of the circular plate 505 can prevent the hand from slipping when rotating the circular plate 505, thereby facilitating the rotation of the circular plate 505. The rotation of the circular plate 505 will drive the threaded rod 501 to rotate. The rotation of the threaded rod 501 will move in the generator housing 1 with the help of the thread. The movement of the threaded rod 501 will drive the elliptical block 502 to move. The elliptical block 502 will gradually disengage from the groove 503 and gradually enter the elliptical groove 504. When the elliptical block 502 After completely sliding into the elliptical groove 504, the elliptical block 502 reaches the position of limiting the rectangular bar 3, and then limits the position of the stator core shell 2, so as to facilitate the fixed connection of the stator core shell 2 to the generator housing 1, and then release the latch 512. The latch 512 will be inserted into the circular groove 510 with the help of the contraction force of the spring 513. After the latch 512 is inserted into the circular groove 510, the latch 512 reaches the function of limiting the rotation of the circular plate 505, thereby further improving the stability of the elliptical block 502 in limiting the position of the stator core shell 2. The spring 513 reaches the position of limiting the latch 512, thereby preventing the latch 512 from falling out of the circular groove 510 due to shaking.
