[0012] Explanation of reference numerals in the attached drawings: frame body 100, upper frame 100-1, lower frame 100-2, side of frame 100-3, oscillating pin assembly mounting position 1, upper shaft assembly mounting position 2, winding device assembly mounting position 3, pattern assembly mounting position 4, motor mounting position 5, lower shaft assembly mounting position 6, shock absorber seat 7. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings:

[0014] Referring to the attached diagram: This sewing machine frame structure includes a frame body 100, which is used to install various components of the sewing machine to form a complete sewing machine for operation. The frame body 100 is made of aluminum alloy and is integrally molded. This use of aluminum alloy for the frame body 100 achieves a lightweight effect, solving the defects of traditional frames made of cast iron, such as large weight, poor corrosion resistance, high noise, and long assembly cycle. The use of aluminum alloy for the frame body 100 achieves a lightweight effect, improves processing efficiency, improves corrosion resistance, shortens the assembly cycle, reduces vibration and noise, reduces overall weight, and reduces transportation and production costs.

[0015] The rack body 100 includes an upper rack part 100-1 and a lower rack part 100-2. The upper rack part 100-1 is located above the lower rack part 100-2. The sides of the upper rack part 100-1 and the lower rack part 100-2 are connected to rack side parts 100-3. The upper rack part 100-1, the lower rack part 100-2, and the rack side parts 100-3 form an inverted concave shape. With this configuration, the entire rack body 100 consists of three parts: the upper rack part 100-1, the lower rack part 100-2, and the rack side parts 100-3. The inverted concave shape of the upper rack part 100-1, the lower rack part 100-2, and the rack side parts 100-3 enhances the stability of the entire rack body.

[0016] The upper part 100-1 of the frame has, from left to right, three mounting positions: a bobbin assembly mounting position 1 for mounting the bobbin assembly, an upper shaft assembly mounting position 2 for mounting the upper shaft assembly, and a winder assembly mounting position 3 for mounting the winder assembly. This arrangement ensures that the bobbin assembly mounting position 1, upper shaft assembly mounting position 2, and winder assembly mounting position 3 are used to install the corresponding structures, and the layout is reasonable, improving assembly efficiency. The corresponding structures are standard sewing machine structures and will not be described further.

[0017] The side of the frame 100-3 is provided with, from top to bottom, a pattern assembly mounting position 4 for mounting the pattern assembly and a motor mounting position 5 for mounting the motor. This arrangement allows the pattern assembly mounting positions 4 and 5 to be used to install the corresponding structures, and the layout is reasonable, improving assembly efficiency. The corresponding structures are the conventional structures of sewing machines, and will not be described in detail.

[0018] The lower part 100-2 of the frame is provided with a lower shaft assembly mounting position 6 for accommodating the lower shaft assembly. This design allows the lower shaft assembly mounting position 6 to be used to install the corresponding structure, and the arrangement is reasonable, improving assembly efficiency. The corresponding structure is a conventional sewing machine structure, which will not be described in detail.

[0019] A vibration damping seat 7 is installed on the lower part 100-2 of the frame. This arrangement, using the vibration damping seat 7, forms a vibration damping module, which can solve the inherent defects of the material and reduce vibration noise.

[0020] In use, install the corresponding structures on the bobbin assembly mounting position 1, upper shaft assembly mounting position 2, winding device assembly mounting position 3, pattern assembly mounting position 4, motor mounting position 5, and lower shaft assembly mounting position 6 onto the frame body 100, and then install the remaining conventional structures onto the frame body 100 to complete the installation of the sewing machine.

[0021] The features of this utility model embodiment are: the frame body made of aluminum alloy material achieves the effect of material lightweighting, improves processing efficiency, improves corrosion resistance, shortens assembly cycle, reduces vibration and noise, reduces overall weight, reduces transportation costs, reduces production costs, has good performance, and is easy to promote.

[0022] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
