Description

Technical Field

[0001] This invention relates to the field of model exterior decoration in automobile manufacturing, specifically to a method and apparatus for creating a clay model that simulates quilting effects. Background Technology

[0002] Car development requires the creation of clay models to showcase the visual form. Clay is a type of modeling clay that can be easily manipulated with tools. Quilting, as part of the design, is also necessary when creating clay models.

[0003] The traditional method for creating quilted effects on clay models involves making stitches on fabric (such as cloth or leather) and then attaching the fabric to the clay model. However, this traditional method has the following problems: to ensure even stitches, a sewing machine is needed to make the stitches on the fabric, requiring the operator to have sewing machine skills; and because the surface of clay models is usually curved, there are difficulties in positioning the flat fabric when unfolding it onto the model. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a method and apparatus for creating a clay model that simulates quilting effects. This method allows for direct drilling and quilting arrangement on the clay model, ensuring consistency between the quilting direction and the design direction, accurate positioning, and saving time and effort.

[0005] To achieve the above objectives, this invention provides a method for creating a clay model that simulates the effect of quilted stitching, specifically including the following steps:

[0006] Create a stitch dotting tool consisting of multiple sewing needles arranged side by side, and adjust the spacing between the sewing needles in the stitch dotting tool according to the stitch length of the designed quilting.

[0007] Based on the quilting pattern designed on the clay model, the needle eye of the sewing needle in the stitch dotting tool is pressed into the clay model to form the quilting needle hole;

[0008] The stitching is placed according to the quilting direction designed on the clay model, and the stitching above the needle hole is pressed to a set length into the needle hole using a stitching pressing tool to create a simulated quilting effect.

[0009] Based on the above technical solutions,

[0010] The stitching tool includes a flexible cardboard and multiple sewing needles;

[0011] The cardboard includes opposing first and second surfaces;

[0012] The sewing needles are arranged in a parallel pattern on the cardboard according to the designed spacing.

[0013] Based on the above technical solution, the specific steps of adjusting the spacing of each sewing needle tip in the stitch marking tool according to the designed quilting stitch length include:

[0014] Mark the stitch length on the first surface of the cardstock according to the designed quilting stitch length;

[0015] According to the stitch length markings, the sewing needle tip is inserted from the first surface to the second surface at the bottom of the cardboard, and then from the second surface to the first surface at the top of the cardboard.

[0016] Adjust the length of the sewing needle on the cardstock so that the eye of the sewing needle extends outward from the bottom of the cardstock and remains flush.

[0017] Based on the above technical solution, the quilting includes straight quilting, square wave quilting, and curved quilting.

[0018] Based on the above technical solution, for straight quilting, according to the direction of the quilting designed on the clay model, the needle eye of the sewing needle in the stitch dotting tool is pressed into the clay model to form the needle hole of the quilting. The specific steps are as follows:

[0019] According to the direction of the quilting in the design, stick the tape to the surface of the clay model, and align the edge of the tape with the quilting.

[0020] Press the eye of the sewing needle from the stitching tool into the clay model along the edge of the tape to form a straight quilting needle hole.

[0021] Based on the above technical solution, for square wave quilting, the quilting needle hole is formed by pressing the eye of the sewing needle in the stitch dotting tool into the clay model according to the quilting direction designed on the clay model. The specific steps are as follows:

[0022] According to the direction of the quilting in the design, stick the tape to the surface of the clay model, keeping the edge of the tape aligned with one of the two parallel quilting seams in the square wave quilting. Along the edge of the tape, press the eye of the sewing needle in the stitch dotting tool into the clay model.

[0023] Apply the tape to the surface of the clay model again, keeping the edge of the tape aligned with the other slit of the two parallel slits in the square wave slit. Along the edge of the tape, press the eye of the sewing needle from the stitch dotting tool into the clay model to form the needle hole of the square wave slit.

[0024] Based on the above technical solution, for curved quilting, according to the quilting direction designed on the clay model, the needle eye of the sewing needle in the stitch dotting tool is pressed into the clay model to form the quilting needle hole. The specific steps are as follows:

[0025] Based on the design of the quilting direction, print the required curves on tape and stick the tape to the surface of the clay model;

[0026] Press the eye of the sewing needle in the stitching tool into the clay model along the curve of the tape to form a curved honed stitch.

[0027] Based on the above technical solutions,

[0028] The suture pressing tool includes a handle and a needle with one end inserted into the handle;

[0029] The needle in the suture pressing tool is a sewing needle, and the eye of the sewing needle is ground to expose a notch.

[0030] Based on the above technical solution, the process involves placing the sewing thread according to the quilting direction designed on the clay model, and pressing the sewing thread above the needle hole to a set length using a sewing thread pressing tool to create a simulated quilting effect. Specific steps include:

[0031] The stitches are placed according to the direction of the quilting designed on the clay model, and the reserved thread length between adjacent needle holes in the clay model is a preset multiple of the needle hole spacing.

[0032] The pre-existing suture thread above the needle hole is pressed into the needle hole using a suture pressing tool to create a simulated quilted suture effect.

[0033] This invention provides a device for creating clay models to simulate quilted stitch effects, comprising:

[0034] The stitch dotting tool consists of multiple sewing needles arranged in parallel, with the spacing between each sewing needle corresponding to the designed stitch length of the quilting. The stitch dotting tool is used to press the eye of its own sewing needle into the clay model according to the direction of the quilting designed on the clay model, forming the needle hole of the quilting.

[0035] A thread pressing tool is used to press the thread above the needle hole to a set length into the needle hole after the thread is placed according to the quilting direction designed on the clay model, so as to form a simulated quilting effect.

[0036] Compared with the prior art, the advantages of this invention are as follows: By creating a stitch dotting tool composed of multiple sewing needles arranged in parallel, and adjusting the spacing of each sewing needle in the stitch dotting tool according to the designed stitch length of the quilting, and then pressing the eye of the sewing needle in the stitch dotting tool into the clay model according to the quilting direction designed on the clay model, the needle hole of the quilting is formed. Finally, the sewing thread is placed according to the quilting direction designed on the clay model, and the sewing thread above the needle hole is pressed into the needle hole by a sewing thread pressing tool to a set length, forming a simulated quilting thread effect. By using the stitch dotting tool and the sewing thread pressing tool, the punching and sewing thread arrangement can be directly set on the clay model, which saves time and effort while ensuring the consistency between the sewing thread direction and the design direction and the positioning accuracy.

[0041] This invention provides a method for creating a simulated quilting effect on a clay model. The method involves creating a stitch-marking tool composed of multiple sewing needles arranged in parallel. The spacing between the needles in the tool is adjusted according to the designed stitch length. Then, based on the designed quilting direction on the clay model, the eye of each needle in the stitch-marking tool is pressed into the clay model to form a needle hole. Finally, the thread is placed according to the designed quilting direction on the clay model, and a thread pressing tool is used to press the thread above the needle hole to a set length into the needle hole, creating a simulated quilting effect. By using the stitch-marking tool and the thread pressing tool, holes are punched and the thread is arranged directly on the clay model, ensuring consistency between the thread direction and the designed direction, accurate positioning, and saving time and effort. This invention also provides a corresponding apparatus for creating a simulated quilting effect on a clay model.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0043] See Figure 1 As shown in the figure, the method for creating a clay model to simulate quilting effects according to an embodiment of the present invention specifically includes the following steps:

[0044] S1: Create a stitch dotting tool consisting of multiple sewing needles arranged side by side, and adjust the spacing between each sewing needle in the stitch dotting tool according to the stitch length of the designed quilting.

[0045] See Figure 2 As shown, in this invention, the stitch dotting tool includes a freely bendable cardboard and a plurality of sewing needles; the cardboard includes a first surface and a second surface opposite to each other; the sewing needles are arranged side by side on the cardboard according to the designed spacing. Figure 2 In the diagram, 1 represents cardboard and 2 represents a sewing needle.

[0046] In this invention, the spacing between the needles of each sewing needle in the stitch marking tool is adjusted according to the designed stitch length of the quilting. Specific steps include:

[0047] S101: Mark the stitch length on the first surface of the cardstock according to the designed quilting stitch length;

[0048] S102: According to the stitch length markings, insert the sewing needle tip from the first surface into the second surface at the bottom of the cardboard, and from the second surface into the first surface at the top of the cardboard.

[0049] S103: Adjust the threading length of the sewing needles on the cardstock so that the needle eyes extend outward from the bottom of the cardstock and remain aligned. In the same stitch marking tool, after all sewing needles have been threaded onto the cardstock, they are arranged according to the stitch length markings.

[0050] In practical applications, the needle spacing of quilting in different parts of a vehicle may vary. Therefore, multiple stitch dotting tools can be created. By adjusting the spacing of the sewing needles in each stitch dotting tool, different stitch dotting tools can be used to correspond to different parts.

[0051] S2: Based on the quilting direction designed on the clay model, the needle eye of the sewing needle in the stitch dotting tool is pressed into the clay model to form the quilting needle hole;

[0052] In this invention, quilting includes straight quilting, square wave quilting, and curved quilting.

[0053] In this invention, for straight quilting, the step of forming the quilting needle hole by pressing the eye of the sewing needle in the stitch dotting tool into the clay model according to the quilting direction designed on the clay model is as follows:

[0054] S201: According to the designed quilting direction, apply tape to the surface of the clay model, aligning the edges of the tape with the quilting; it should be noted that the tape in this invention has weak adhesion and is easy to remove.

[0055] S202: Press the eye of the sewing needle in the stitching tool into the clay model along the edge of the tape to form a straight quilting needle hole.

[0056] In this invention, for square wave quilting, the step of forming quilting needle holes by pressing the eye of the sewing needle in the stitch dotting tool into the clay model according to the quilting direction designed on the clay model is as follows:

[0057] S211: According to the direction of the quilting in the design, stick the tape to the surface of the clay model, keep the edge of the tape aligned with one of the two parallel quilting seams in the square wave quilting, and press the eye of the sewing needle in the stitch dotting tool into the clay model along the edge of the tape.

[0058] S212: Attach the tape to the surface of the clay model again, keeping the edge of the tape aligned with the other slit of the two parallel slits in the square wave slit. Along the edge of the tape, press the eye of the sewing needle in the stitching tool into the clay model to form the needle hole of the square wave slit.

[0059] In this invention, for curved quilting, the quilting holes are formed by pressing the eye of the sewing needle in the stitching tool into the clay model, according to the quilting direction designed on the clay model. The specific steps are as follows:

[0060] S221: Based on the direction of the quilting in the design, print the required curve on the tape and stick the tape to the surface of the clay model;

[0061] S222: Press the eye of the sewing needle in the stitching tool into the clay model along the curve on the tape to form a curved honed stitch hole. That is, bend the cardboard of the stitching tool according to the curvature of the curve on the tape so that the curvature is consistent with the curvature of the curve on the tape.

[0062] It should be noted that due to the size limitations of the stitch dotting tool, it is impossible to complete the needle hole pressing in one go for a single quilting stitch. In actual operation, after pressing the eye of the sewing needle into the clay model to form a needle hole, the stitch dotting tool is pulled out and moved to the next position along the quilting stitch, and the pressing is repeated, and so on, until the needle holes for a single quilting stitch are completed.

[0063] S3: Place the stitching according to the quilting direction designed on the clay model, and use the stitching pressing tool to press the stitching above the needle hole to a set length into the needle hole to form a simulated quilting effect.

[0064] See Figure 3 As shown, in this invention, the suture pressing tool includes a handle and a needle with one end inserted into the handle; the needle is elongated, with a semi-circular or oblong groove at one end, and the other end inserted into and fixed to the handle. The handle can be made of wood or plastic, with a diameter and length suitable for one-handed operation, and a hardness suitable for inserting and securing the needle. Figure 3 In the diagram, 3 represents the handle and 4 represents the needle body.

[0065] Furthermore, the needle in the thread pressing tool is a sewing needle, and the eye of this sewing needle is ground to expose a notch. In actual production, the needle can be made from an ordinary sewing needle. By selecting a sewing needle with a thickness similar to the required quilting thread, the eye of the needle is ground to expose a notch, and the edges of the notch are smoothed. Simultaneously, depending on the thickness of the quilting thread, quilting needles of different sizes need to be made, requiring the semi-circular opening of the sewing needle to be slightly larger than the thread diameter.

[0066] In this invention, the stitching is placed according to the quilting pattern designed on the clay model, and a stitching pressing tool is used to press the stitching above the needle hole to a set length into the needle hole, forming a simulated quilting effect. Specific steps include:

[0067] S301: The stitches are placed according to the direction of the quilting designed on the clay model, and the reserved thread length between adjacent needle holes in the clay model is a preset multiple of the needle hole spacing; in one possible implementation, the reserved thread length between adjacent needle holes is 150% of the needle hole spacing.

[0068] S302: The pre-reserved suture above the needle hole is pressed into the needle hole by the suture pressing tool to form a simulated quilting effect.

[0069] This means that when placing the thread, the length of the thread should be greater than the length of the quilting. When pressing the thread, place the end of the needle of the thread pressing tool above the thread at the needle eye, then insert the end of the needle into the needle eye to press a portion of the thread into the needle eye, keeping the thread between adjacent needle eyes taut. This process is repeated along the needle eye sequence, pressing a certain length of thread above each needle eye into the needle eye to create a simulated quilting effect.

[0070] For the ends of the thread, press the beginning of the thread into the first needle hole to ensure it is not exposed, and press the end of the thread into the last needle hole to ensure it is not exposed.

[0071] The method for creating a simulated quilting effect using a clay model according to this invention involves creating a stitch dotting tool composed of multiple sewing needles arranged in parallel. The spacing between the needles in the stitch dotting tool is adjusted according to the designed stitch length. Then, based on the quilting direction designed on the clay model, the eye of the sewing needle in the stitch dotting tool is pressed into the clay model to form a quilting hole. Finally, the thread is placed according to the quilting direction designed on the clay model, and a thread pressing tool is used to press the thread above the needle hole to a set length into the needle hole, creating a simulated quilting effect. By using the stitch dotting tool and the thread pressing tool, holes are directly punched and the thread is arranged on the clay model, ensuring consistency between the thread direction and the design direction, accurate positioning, and saving time and effort.

[0072] In one possible implementation, the present invention also provides a readable storage medium located in an MCU (Micro Control Unit) controller. The readable storage medium stores a computer program that, when executed by a processor, implements the steps of the method for creating a clay model simulating quilting effects as described below:

[0075] The stitching is placed according to the quilting direction designed on the clay model, and the stitching above the needle hole is pressed to a set length into the needle hole using a stitching pressing tool to create a simulated quilting effect.

[0083] According to the direction of the quilting in the design, stick the tape to the surface of the clay model, and align the edge of the tape with the quilting.
