Since the electric control outer cover side cover is fixedly connected to the casing by screws, when it is necessary to open the electric control outer cover side cover to perform maintenance, upgrade, etc. on the electric control box, the disassembly and assembly of the screws requires tools, and the screws are easy to lose, resulting in the situation where the electric control outer cover side cover cannot be fixed. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an electronic control device for a sewing machine to solve the above-mentioned problems.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic control device for a sewing machine, comprising a sewing machine head, an electronic control body and an electronic control side cover, the electronic control body being arranged at one end of the sewing machine head, one side of the electronic control body extending to the outside of the sewing machine head, one end of the electronic control side cover being arranged at a side of the electronic control body extending to the outside of the sewing machine and being hinged, and a connecting device being arranged between the other end of the electronic control side cover and the sewing machine head.

[0005] Preferably, the connecting device comprises a first connecting hole, a first magnetic block is arranged in the first connecting hole, and the first magnetic block is attracted and connected to the sewing machine head.

[0006] The beneficial technical effect of the utility model is that the other end of the electric control side cover is magnetically fixed to the sewing machine head through the connecting device, so that the electric control side cover is stably connected to the sewing machine head, improving the stability of the overall structure, and at the same time, when it is necessary to open the electric control side cover to perform maintenance, upgrade and other operations on the electric control body in the future, it is only necessary to apply a rotational force to the electric control side cover until the rotational force is greater than the magnetic force generated by the first magnetic block and the second magnetic block, so that the electric control side cover can be rotated, thereby repairing and upgrading the electric control body.

[0011] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0012] Example 1, reference Figure 1-3 As shown, an electric control device for a sewing machine comprises a sewing machine head 1, an electric control body 2 and an electric control side cover 3, wherein the electric control body 2 is arranged at one end of the sewing machine head 1, and one side of the electric control body 2 extends to the outside of the sewing machine head 1, one end of the electric control side cover 3 is arranged on the side of the electric control body 2 extending to the outside of the sewing machine and is hinged, a connecting device 4 is arranged between the other end of the electric control side cover 3 and the sewing machine head 1, the connecting device 4 comprises a first connecting hole 41, a first magnetic block 42 is arranged in the first connecting hole 41, the first magnetic block 42 is attracted and connected with the sewing machine head 1, one side of the electric control body 2 extends to the outside of the sewing machine head 1, one end of the electric control side cover 3 is arranged on the side of the electric control body 2 extending to the outside of the sewing machine and is hinged, a clamping block 5 is arranged on the electric control body 2 towards the electric control body 2, and the electric control body 2 is provided with a protrusion 6, and the clamping block 5 is clamped with the protrusion 6.

[0013] When in use, the electric control body 2 is installed on the rear end of the sewing machine head 1, and the front end of the electric control side cover 3 is hinged to the rear end of the electric control body 2 extending to the outside of the sewing machine head 1, so that the electric control side cover 3 is rotatably arranged on the rear end of the electric control body 2 extending to the outside of the sewing machine head 1, and the other end of the electric control side cover 3 is magnetically fixed to the sewing machine head 1 through the connecting device 4, so that the electric control side cover 3 is stably connected to the sewing machine head 1, thereby improving the stability of the overall structure. At the same time, when it is necessary to open the electric control side cover 3 to perform maintenance, upgrading and other operations on the electric control body 2 in the future, it is only necessary to apply a rotational force to the electric control side cover 3 until the rotational force is greater than the magnetic force generated between the first magnetic block 43 and the sewing machine head 1, so that the electric control side cover 3 can be rotated, thereby performing maintenance and upgrading on the electric control body 2.
