Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically a DC micro motor structure with winding interlocking and reinforcement. Background Technology

[0002] In practical applications of DC micro motors, the stator core and coils are the core components for energy conversion, and their stability directly determines the performance and lifespan of the motor. Traditional DC micro motors often use an integral structure for the stator core, with the coils directly wound in the core slots. During the stamping process, the integral core produces a lot of waste from the edges of the silicon steel sheets, resulting in low raw material utilization and increased production costs. Furthermore, the integral production process makes it impossible to effectively repair the worn parts during subsequent use, requiring complete replacement. Therefore, we propose a DC micro motor structure with reinforced winding interlocking. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a DC micro motor structure with winding interlocking and reinforcement, which effectively solves the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a DC micro motor structure with winding interlocking reinforcement, including a chassis, an interlocking stator is provided inside the chassis, the interlocking stator includes multiple sets of splicing blocks, a first arc-shaped portion is provided on the left side of the splicing block, a second arc-shaped portion is provided on the right side of the splicing block, and the inner wall of the splicing block is connected to the interlocking block.

[0005] Preferably, the front and rear sides of the splicing block are connected with retaining rings, and the outer side of the splicing block is provided with an auxiliary ring.

[0006] Preferably, the upper side of the interlocking block is provided with a convex part, and the lower side of the interlocking block is provided with a blocking part.

[0007] Preferably, the splicing block has insertion holes at both the first and second arc-shaped points, and insertion rods are provided inside the insertion holes.

[0008] Preferably, the outer sides of the retaining ring and the auxiliary ring are provided with functional grooves, and the bodies of the retaining ring and the auxiliary ring are provided with assembly holes.

[0009] Preferably, the splicing block has an auxiliary groove on its upper side.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting multiple sets of splicing blocks, when a part of the mating stator fails, it is not necessary to replace the whole stator as in the case of an integral stator. Only the damaged splicing block or mating block needs to be disassembled and replaced, which greatly reduces maintenance costs and difficulties, shortens maintenance time, and improves the convenience of motor maintenance and the economy of use.

[0012] 2. By setting retaining rings and auxiliary rings to limit and protect the splicing blocks, the stability of fixing multiple sets of splicing blocks is improved. By setting insert rods to limit the two sets of splicing blocks, the stability of the mating stator assembly is further improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A winding-interlocked reinforced DC micromotor structure includes a chassis 100, inside which is an interlocking stator 200. The interlocking stator 200 includes multiple sets of splicing blocks 210. A first arc-shaped portion 211 is provided on the left side of each splicing block 210, and a second arc-shaped portion 212 is provided on the right side. An auxiliary groove 213 is provided on the upper side of each splicing block 210. During use, the multiple splicing blocks 210 are joined together in a circular shape, and the arc shape restricts their movement in all directions, preventing them from moving up, down, left, or right. The disengagement direction is also arc-shaped, thus improving the multi-set splicing efficiency. The stability of the splicing of blocks 210 is improved, enhancing the quality of the mating stator 200. The auxiliary groove 213 reduces stress generated during use of the splicing blocks 210, further improving their stability. Insertion holes 214 are provided at both the first arc 211 and the second arc 212 of the splicing blocks 210. Insertion rods 215 are installed inside the insertion holes 214, limiting the movement of the two sets of splicing blocks 210 and thus improving the stability of the mating stator 200 assembly, thereby enhancing the overall safety of the mating stator 200. To ensure safety and stability, the inner wall of the splicing block 210 is connected to a fitting block 220. The fitting block 220 can be used to isolate and install the coil. Retaining rings 230 are connected to both the front and rear sides of the splicing block 210, and an auxiliary ring 240 is provided on the outer side of the splicing block 210. The retaining ring 230 can be welded to the splicing block 210 or the auxiliary ring 240 as needed, or it can be connected using a high-strength coating. The retaining rings 230 and the auxiliary rings 240 limit and protect the splicing block 210, improving the stability of multiple splicing blocks 210. 10. For fixed stability, the outer sides of the retaining ring 230 and the auxiliary ring 240 are provided with working grooves, and the bodies of the retaining ring 230 and the auxiliary ring 240 are provided with assembly holes. The assembly holes facilitate the quick connection of the retaining ring 230 and the auxiliary ring 240, improving the stability of the device. The upper side of the fitting block 220 is provided with a convex part 221, and the lower side of the fitting block 220 is provided with a blocking part 222. The convex part 221 facilitates the fitting block 220 to be inserted into the splicing block 210, and the blocking part 222 facilitates the installation and fixation of the coil.
