Description

Technical Field

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

[0002] In the automotive and general machinery sectors, the idle speed motor, as a key component controlling the intake air volume of the engine during idling, 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 is the core supporting component of the idle speed motor, and its structural design directly affects its performance, which in turn relates to the engine's idle speed stability, fuel economy, and exhaust emission quality.

[0003] Most existing motors adopt a one-piece structure design, where core components (such as coil frames, wiring assemblies, and housings) are connected as a single unit through welding, integral injection molding, or non-separable fixing methods. This presents challenges in replacing damaged parts. In a one-piece structure, if a component (such as wiring pins or coil leads) is damaged due to wear, corrosion, or malfunction, the entire motor or a large assembly containing the damaged part must be replaced because it cannot be disassembled and replaced individually, resulting in material waste. Therefore, a new type of motor needs to be designed.

[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 to solve the problem that in the existing integrated motor structure, when some parts are damaged, they cannot be disassembled and replaced individually, and the whole or a large component needs to be replaced, resulting in material waste and replacement difficulties.

[0006] The present invention adopts the following technical solution: a motor, mainly including a protective part, which is composed of a top cover and a bottom cover; a wiring part, which is disposed inside the bottom cover, the wiring part is used to realize a stable connection between the winding and the external circuit and efficient conduction of electrical energy, the wiring part includes a coil frame disposed inside the bottom cover, and a stepped structure extends outward from the edge of the top opening of the bottom cover, the stepped structure bearing a mounting part for realizing a predetermined position with the top of the coil frame.

[0007] Furthermore, the mounting part is composed of socket shell one and socket shell two fitted together in layers. Socket shell two has a semi-cylindrical concave structure. The concave cavity at the bottom of socket shell two is adapted to the top contour of the coil skeleton. Socket shell one has an inner groove at the bottom. A flange extends outward from the bottom edge of socket shell one. Two sets of mating blocks are symmetrically arranged on the flange. Socket shell two is adapted to have a mating groove. The mating blocks and the mating groove at the bottom of socket shell two are assembled by sliding insertion.

[0008] Furthermore, the coil frame includes a main body cylinder, which is injection molded from high-strength insulating material. The inner wall of the main body cylinder has a smooth through hole that mates with the shaft of the motor rotor.

[0009] Furthermore, the outer wall of the main body is provided with three sets of winding baffles, which are distributed in an equidistant ring array. The winding baffles are formed with the main body using an integrated injection molding process, and the winding baffles have an annular protruding structure.

[0010] Furthermore, a fan-shaped boss is provided near the top of the main body cylinder. The fan-shaped boss is an integrated injection-molded structure. The fan-shaped outline of the fan-shaped boss is adapted to the winding area. One side of the fan-shaped boss is seamlessly connected to the upper winding baffle to form an L-shaped support. Multiple sets of wiring pins are vertically arranged on the fan-shaped boss. The wiring pins are made of tin-plated brass. The base of the wiring pins is fixed to the fan-shaped boss by injection molding.

[0011] Furthermore, the socket housing one has a coil pin, which adopts an L-shaped bend with a notch end structure. One end of the coil pin passes through the socket housing one and extends into the enclosing space enclosed by the socket housing one and the socket housing two. The notch end of the coil pin cooperates with the wiring pin.

[0012] Furthermore, the top cover is a cylindrical structure with an open bottom, while the bottom cover is open at the top. The two are assembled by a mating fitting method, and the opening edge of the top cover and the top opening of the bottom cover are adapted to fit and enclose to form a closed covering space.

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

[0014] A motor, comprising a top and bottom protective cover, employs a split design to replace the traditional one-piece cover. The two covers are assembled by mating and fitting together, allowing for easy disassembly. When internal components are damaged, the cover can be opened without disrupting the overall structure, avoiding the destructive operations required when disassembling a one-piece motor. This provides a basis for replacing individual components and reduces material waste caused by replacing the entire motor. The wiring section and mounting section are separately designed, with the mounting section supported by a stepped structure on the bottom cover and pre-positioned with the top of the coil frame. This allows core components such as the coil frame and mounting section to be independently disassembled and assembled. The split design of each component, combined with a precise positioning structure, improves maintenance convenience while ensuring assembly. During routine maintenance, components can be quickly disassembled for inspection, and damaged parts can be replaced promptly, avoiding the drawback of requiring the entire motor to be replaced due to partial faults, as is common in one-piece motors.

[0023] 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.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-4 As shown in the figure, an embodiment of the present invention provides a motor including a protective part, which is composed of a top cover 1 and a bottom cover 2. The top cover 1 is a cylindrical structure with an open bottom; the bottom cover 2 has an open top. The two are assembled by a mating fitting method. The edge of the opening of the top cover 1 is precisely matched with the top opening of the bottom cover 2 to form a closed enclosure space, which provides protection for the internal coil frame and electrical connectors, prevents external dust and moisture from entering, and ensures a stable operating environment for the core components of the motor.

[0026] Furthermore, a wiring section is provided inside the bottom cover 2. This wiring section includes a coil frame 3 located inside the bottom cover 2. The coil frame 3 is based on the main body 31 as the core supporting structure. The main body 31 is injection molded from high-strength insulating materials (such as modified nylon, phenolic resin, etc.). The inner wall has a smooth through hole, which cooperates with the shaft / iron core and other components of the motor rotor 6 to ensure the coaxiality and stability of the rotor during rotation. The outer wall is designed as a flat cylindrical surface to serve as a support surface for winding the enameled wire.

[0027] Furthermore, three sets of winding baffles 32 are provided on the outer wall of the main body cylinder 31. These three sets of winding baffles 32 are distributed in an equidistant ring array and are formed with the main body cylinder 31 using an integrated injection molding process. The winding baffles 32 have a ring-shaped protruding structure, which not only restricts the displacement of the enameled wire during winding and operation by axial blocking to prevent the winding from becoming loose, but also enhances the radial stiffness of the main body cylinder 31 by using the ring structure to disperse the winding tension and the electromagnetic force of the motor during operation, and prevents the frame from deforming.

[0028] A fan-shaped protrusion 4 is provided near the top of the main body cylinder 31. The fan-shaped protrusion 4 is an integrated injection molding structure. The fan-shaped outline of the fan-shaped protrusion 4 is adapted to the winding area. One side is seamlessly connected to the upper winding baffle 32 to form an L-shaped support. Multiple sets of wiring pins 5 are vertically arranged on the fan-shaped protrusion 4. The wiring pins 5 are made of tin-plated brass, and their roots are fixed to the fan-shaped protrusion 4 by injection molding.

[0029] Meanwhile, a stepped structure extends outward from the edge of the top opening of the bottom cover 2. This stepped structure supports the mounting part, which is composed of socket shell 1 7 and socket shell 2 8 fitted together in layers. Socket shell 2 8 is a semi-cylindrical concave structure. The bottom concave cavity matches the top contour of the coil frame 3, which plays a pre-positioning role. Socket shell 1 7 has an inner groove at the bottom. At the same time, a flange (not shown in the figure) extends outward from the bottom edge of socket shell 1 7. Two sets of mating blocks 72 are symmetrically arranged on the flange. At the same time, a mating groove 81 is adapted to be opened on socket shell 2 8. The mating blocks 72 and the mating groove 81 at the bottom of socket shell 2 8 are slid-fitted together to achieve quick positioning and ensure the coaxiality of the mounting part with the coil frame 3 and the cover.

[0030] Furthermore, the socket housing 7 has a coil pin 71, which adopts an L-shaped bend and notch design. One end of the coil pin 71 passes through the socket housing 7 and extends into the enclosed space between the socket housing 7 and the socket housing 8. The notch end of the coil pin 71 contacts the wiring pin 5. During assembly, the notch can automatically correct minor deviations to ensure contact between the pin and the wiring pin. The other end extends out of the housing as an external wiring terminal for the motor, which is adapted to the circuit board or wire harness through standardized pin spacing.

[0031] Working principle: During use, the external circuit receives current through the coil pin 71 extending out of the housing of the socket housing 7. The current flows through the precise contact between the coil pin 71 and the wiring pin 5 on the fan-shaped boss 4, and flows into the enameled wire winding wound on the outer wall of the coil frame 3. At this time, the winding generates an alternating magnetic field in the regular space formed by the main body cylinder 31 and the three sets of winding baffles 32. Since the rotor part 6 assembled in the through hole in the inner wall of the main body cylinder 31 is in this magnetic field, according to the left-hand rule, the rotor will be subjected to electromagnetic torque and rotate around the axis, realizing the conversion of electrical energy into mechanical energy.

[0032] During this process, the enclosed space formed by the top cover 1 and the bottom cover 2 blocks external dust and moisture from interfering with the internal components. The three sets of winding baffles 32 ensure stable magnetic field distribution by limiting the displacement of the windings. The L-shaped support structure of the fan-shaped boss 4 enhances the mechanical stability of the wiring part. The layered fitting design of the socket housing 1 7 and the socket housing 2 8 ensures that the coil pin 71 and the wiring pin 5 always maintain reliable contact through the sliding fit of the mating block 72 and the mating groove 81, ultimately enabling the motor to output power stably.

[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.
