Description

Technical Field

[0001] This utility model relates to the field of coil frame technology, and in particular to motor coil frames. Background Technology

[0002] In the automotive and general machinery sectors, the idle speed motor, as a key component controlling the intake air volume of an engine at idle, plays a decisive role in the idling stability of cars, motorcycles, and general machinery. The idle speed motor adjusts the opening of the intake passage through an internal structure driven by a motor. The motor coil frame is the core supporting component of the idle speed motor, and its structural design directly affects the motor's performance, which in turn relates to the engine's idle speed stability, fuel economy, and exhaust emission quality.

[0003] However, existing motor coil frames used in idle speed motors have defects. As a core component for precisely controlling the engine's idle air intake, the idle speed motor requires high precision in assembling the coil frame with components such as the magnetic core and housing. Traditional frames lack positioning structures, making them prone to deviations during manual assembly, increasing product debugging costs and defect rates. Therefore, it is necessary to design a new motor coil frame.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a motor coil frame to solve the problems of existing idle speed motor coil frames lacking positioning structures, making it difficult to meet assembly accuracy, and being prone to deviation during manual assembly.

[0006] The present invention adopts the following technical solution: a motor coil frame, mainly including a main body cylinder; a base platform, which is integrally set on the main body cylinder near the top surface, and the base platform has three sets of positioning slots on its edge; the main body cylinder is provided with a flange for realizing axial positioning of the coil and independent separation of the winding area; and a positioning rib is integrally set on one end edge of the main body cylinder.

[0007] Furthermore, the flange portion includes a layered flange integrally sleeved on the main body cylinder near both the upper and lower ends. The layered flange is disc-shaped, and its outer diameter is larger than that of the main body cylinder. The layered flange has symmetrically arranged notches on its edge.

[0008] Furthermore, each of the two sets of hierarchical flanges has a winding step on one opposite side, and the winding step has a ring-shaped structure.

[0009] Furthermore, a second layer flange is integrally sleeved and fixed in the middle region of the main body cylinder. The structure of the second layer flange is similar to that of the first layer flange. There is a gap between the second layer flange and the first layer flange at the upper and lower ends. The upper layer winding is wound between the upper layer flange and the second layer flange to form a winding space. The lower layer winding is wound between the second layer flange and the lower layer flange.

[0010] Furthermore, the structure of the second layer flange is similar to that of the first layer flange. The edge of the second layer flange has three sets of equidistant notches, two of which are symmetrical and are on the same straight line as the two sets of symmetrical notches of the first layer flange. The remaining notch is on the same straight line as the positioning groove of the base platform.

[0011] Furthermore, the positioning rib has a central inner hole for inserting the motor core.

[0012] Furthermore, multiple sets of wiring pins are installed on the base platform, and the wiring pins are vertically soldered to the fan-shaped plane of the base platform.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] The motor coil frame uses three sets of positioning slots on the edge of the base platform to provide a positioning reference for the assembly of the frame with components such as the magnetic core and housing. During manual assembly, the positioning slots can quickly guide the alignment of each component, effectively avoiding assembly deviations caused by the lack of positioning structure in traditional frames. Secondly, the flange on the main body not only realizes the axial limitation of the coil to prevent axial movement of the coil during operation and ensures the stability of the coil operation, but also makes the coil winding more regular by independently separating the winding area, avoiding mutual interference between different winding areas.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-3 As shown, the motor coil frame provided in this embodiment of the present invention includes a main cylindrical part 1, which is cylindrical in shape and its surface is used for winding enameled wire, electromagnetic wire, etc., which is the basis for coil formation. A base platform 11 with a fan-shaped structure is integrally formed on the surface of the main cylindrical part 1 near the top end. The base platform 11 is coaxial with the main cylindrical part 1, and three sets of positioning slots 111 are opened on the edge of the base platform 11. The cross-section of the positioning slots 111 is a rectangular notch. The positioning slots 111 are distributed circumferentially. The positioning slots 111 are used to limit the virtual boundary during winding to prevent the coil from overflowing radially.

[0025] The base platform 11 serves as the top foundation support surface for the coil frame, and multiple sets of wiring pins 12 are mounted on the base platform 11. The wiring pins 12 are vertically soldered to the fan-shaped plane of the base platform 11. The number and spacing of the pins are adapted to the motor winding design. It should be emphasized that the base of the pins is adjacent to the positioning slot 111 (see...). Figure 1 (Circumferential distribution), the metal plane at the edge of the positioning slot 111 is used to enhance the welding area, improve the vibration resistance of the wiring pin 12, and avoid the pin breakage and poor contact caused by the high-frequency vibration of the idle motor. By welding the wiring pin 12 to the external circuit, the coil wound on the skeleton can be accurately connected to the controller and power supply, so as to realize the stable transmission of the motor drive signal and ensure the idle speed control accuracy.

[0026] Meanwhile, a flange is provided on the main body cylinder 1. The flange includes a layered flange 2 integrally sleeved on the main body cylinder 1 near the upper and lower ends. The layered flange 2 is disc-shaped and its outer diameter is larger than the diameter of the main body cylinder 1. It is used to limit the axial displacement of the coil and prevent the winding from exceeding the skeleton range. It should be noted that the layered flange 2 has symmetrically arranged notches 21 on its edge, rather than being a completely closed disc.

[0027] Furthermore, the notch portion 21 of the relatively set hierarchical flange 2 is shape-adapted and circumferentially aligned, and can engage with the protrusion / slot of the motor housing during assembly to limit the axial movement of the frame;

[0028] In addition, on the opposite side of the two sets of hierarchical flanges 1 and 2 (i.e. the middle area of ​​the main body cylinder 1), there is a winding step 22. The winding step has a ring structure, and its height and width match the coil wire diameter. It can divide the axial space into independent winding areas. At the same time, a hierarchical flange 2 and 3 are integrally sleeved and fixed in the middle area of ​​the main body cylinder 1. Its structure is similar to that of hierarchical flange 1 and 2.

[0029] There is a gap between the second layer flange 3 and the first layer flange 2 at the upper and lower ends. The upper layer winding is wound between the first layer flange 2 and the second layer flange 3 to form a winding space. The lower layer winding is wound between the second layer flange 3 and the first layer flange 2. The winding steps 22 physically separate the windings to avoid short circuits between multiple layers and ensure the stable electrical performance of the motor.

[0030] Furthermore, the structure of the second-level flange 3 is similar to that of the first-level flange 2. The edge of the second-level flange 3 has three sets of equidistant notches 32. Two sets of symmetrical notches 32 are aligned with the two sets of symmetrical notches 21 of the first-level flange 2, used for axial assembly and positioning to ensure the axial alignment accuracy of the multi-level flange. The remaining set of notches 32 is aligned with the positioning groove 111 of the base platform 11 (see...). Figure 1 (circumferential distribution), used for circumferential phase locking between the top and middle layers;

[0031] In addition, a positioning rib 13 is integrally provided on the edge of the main body cylinder 1 away from the wiring pin 12. The positioning rib 13 has a central inner hole, which is not circular, and is used to insert components such as motor core and shaft. The positioning rib 13 is integrally formed with the irregular contour of the inner hole of the main body cylinder 1, and can be engaged with the irregular groove of the magnetic core to achieve circumferential anti-torsion of the frame and the magnetic core.

[0032] Working principle: In use, firstly, coils are wound on the surface of the main body cylinder 1 in independent areas divided by the winding steps 22. The upper winding corresponds to the space between the upper flange 2 and the lower flange 3, and the lower winding corresponds to the space between the lower flange 2 and the lower flange 2. The positioning slot 111 limits the radial boundary of the winding to prevent the coil from overflowing. The coil lead wires are then welded to the wiring pins 12 on the base platform 11. Subsequently, the magnetic core, shaft, and other components are inserted into the non-circular central inner hole of the main body cylinder 1. The circumferential relative position of the frame and the magnetic core is fixed by the engagement of the positioning rib 13 with the irregular groove of the magnetic core. Then, the axial movement of the frame is restricted by the engagement of the notch 21 of the lower flange 2 with the protrusion / slot of the motor housing. At the same time, the notch 32 of the lower flange 3 is aligned with the notch 21 of the lower flange 2 and the positioning slot 111 of the base platform 11, respectively, to achieve axial positioning and circumferential phase locking of the multi-level structure, thus completing the overall assembly.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
