Description

Technical Field

[0001] The invention relates to a magnetic mannequin device for clothing teaching and application thereof, belonging to the technical field of textile and clothing machinery. Background Art

[0002] In the teaching of three-dimensional tailoring of clothing, a mannequin based on a human body model is an indispensable teaching tool. Currently, most mannequins require the production of an integrated metal or wooden inner frame, which is then wrapped with flexible materials such as sponge or foam, and finally wrapped with canvas on the outside. The entire process is relatively complicated.

[0003] Currently, all existing mannequins are one-piece human models that cannot be opened or closed. During the three-dimensional cutting teaching process, multiple pointed bead needles need to be inserted one by one into the corresponding clothing shape lines to fix the fabric or grey cloth (clothing shape lines include front and back center lines, princess lines, shoulder lines, chest lines, waist lines, hip lines, etc.), and then three-dimensional cutting can be carried out.

[0004] However, this avatar has the following problems:

[0005] (1) The integrated human body model is large in size, difficult to store, and takes up a lot of space;

[0006] (2) The traditional production process of mannequins for clothing teaching is complicated and requires a lot of manpower and material resources;

[0007] (3) Pointed bead needles are not only difficult to insert and fix during use, but are also easy to fall off and prick fingers, which is both laborious and a safety hazard. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides a magnetic mannequin device for clothing teaching, comprising a human body model formed by splicing a front half body model and a back half body model at shoulder seams and side seams.

[0009] The human body model comprises a shell and a hollow part of a three-layer structure, wherein the three-layer structure comprises an outer layer, a middle layer and an inner layer, wherein the outer layer is made of a flexible material, the middle layer is made of a semi-rigid material, and the inner layer is made of a rigid material;

[0010] The outer layer, middle layer and inner layer are three-layer structures from the outer surface to the inner surface of the corresponding shell;

[0011] The inner layer is provided with a plurality of micro electromagnets along the positions corresponding to the front and back midline, princess line, shoulder line, chest line, waist line and hip line of the human body; the rest of the inner layer is also provided with a plurality of scattered micro electromagnets;

[0012] Each micro electromagnet comprises a solenoid wound with a coil, an electrode terminal connected to one end of the solenoid by a spring, and an electrode externally connected to the coil and the electrode terminal; when the electrode terminal is pressed and closes the solenoid, the electrode can energize the coil and generate a magnetic field; the electrode can have its own power supply or be powered by an external power supply, and the direction of the magnetic field after the coil is energized is determined by Ampere's law;

[0013] A hollow rod-shaped bracket is installed on the inner surface of the shell. The bracket passes through the hollow part of the human body model and extends from the bottom of the human body model and is connected to a movable platform. The movable platform is a base with pulleys; the human body model can move on the ground through the movable platform.

[0014] The present invention refers to the body position and direction of a natural human body standing on the ground, so in the present invention, the "top" refers to the maximum height from the ground, and the bottom refers to the minimum height from the ground.

[0015] In one embodiment of the present invention, preferably, the material of the outer layer is TPU polyurethane or rubber-like, with a thickness of 5-10 mm; the material of the middle layer is polyurethane-epoxy resin graft blend, with a thickness of 5-10 mm; the material of the inner layer is EPX epoxy resin, with a thickness of 20-30 mm.

[0016] In one embodiment of the present invention, the front and back half of the mannequin are joined at the shoulder and side seams by mortise and tenon joints, which facilitates the opening and closing of the front and back half of the mannequin. The top of the mannequin is a neck, which is further provided with a cover.

[0017] In one embodiment of the present invention, the front half model and the back half model of the human body model are both made by three-dimensional printing technology: for example, the human body data is first transferred to a computer through three-dimensional software modeling or through a human body scanner, the computer is connected to a three-dimensional printing device with independent three nozzles, and the materials required for the outer layer, middle layer, and inner layer are added to the three nozzles respectively. The three-dimensional printing device is started to work, and the human body model is constructed layer by layer through the molten deposition principle of the three nozzles until it is finally formed; the outer layer is also printed with multiple protrusions, which can increase the friction between the outer surface of the shell and the clothing fabric or grey cloth, making the clothing fabric or grey cloth not easy to fall off.

[0018] In one embodiment of the present invention, a power supply is provided in the movable platform, a plurality of through holes are provided on the bracket, and each electrode of the micro electromagnet is provided with a lead wire which passes through the through hole and the hollow part of the bracket in sequence and is connected to the power supply, and the power supply can supply power to each electrode through the lead wire.

[0020] In the present invention, the "shell outer surface" is equivalent to the outer surface of the outer layer, and the "shell inner surface" is equivalent to the inner surface of the inner layer. The "outside" and "inside" of the present invention are both referenced to the "outside the body" and "inside the body" of a natural person.

[0021] The present invention also provides an application of a magnetic mannequin device for clothing teaching in three-dimensional tailoring. First, a suitable human body is selected according to teaching requirements, and the human body is scanned with a three-dimensional human body. After that, a shell of the human body model is printed out with a three-dimensional printer, and a micro electromagnet is installed; then, the clothing fabric or grey cloth is draped on the outer surface of the shell; then, the positions of the front and back center lines, princess lines, shoulder lines, chest lines, waist lines, and hip lines of the human body model are found and pressed with multiple lightweight round-headed bead needles or lightweight steel balls according to tailoring requirements; the electrode terminals are closed with the solenoid due to the pressure transmitted by the multiple lightweight round-headed bead needles or lightweight steel balls through the outer layer and the middle layer, and a magnetic field is generated after the coil is energized, which attracts the lightweight round-headed bead needles or lightweight steel balls to fix the clothing fabric or grey cloth; finally, the three-dimensional tailoring process is demonstrated.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention uses a round-headed bead needle or a steel ball to press the magnetic force generated by the electromagnet to adsorb and fix the clothing fabric or grey cloth, replacing the existing practice of inserting a pointed bead needle into the clothing fabric and the mannequin.
