[0007] A motor end cover of a sewing machine comprises a shell, and is characterized in that more than two bosses are arranged on the shell, and mounting holes for bolts to pass through are respectively opened on the bosses.

[0008] The motor is installed on the shell of the motor end cover, and more than two bosses are arranged on the shell. The shape of the motor end cover is basically adapted to the mounting groove on the casing of the sewing machine. Each boss is provided with a mounting hole. The bolts are threadedly connected to the casing after passing through each mounting hole, so as to realize the installation and fixation of the motor end cover and the casing.

[0009] The shell of the motor end cover is provided with a mounting structure (boss and mounting hole), and the motor end cover can be directly mounted on the casing without the need for an additional fixing frame, which greatly improves the convenience of installation and simplifies the mounting structure.

[0010] In the above-mentioned motor end cover of a sewing machine, the shell has side one, side two, side three and side four, and there are three bosses, one of which is arranged on side one, one of which is arranged at the connection between side two and side three, and one of which is arranged at the connection between side three and side four.

[0011] One boss is located on side one, another boss is arranged at the connection between side two and side three, and another boss is arranged at the connection between side three and side four. Bosses are arranged on the four sides of the shell. After screws are passed through the bosses and threadedly connected to the shell, the force on the motor end cover is more balanced, which greatly improves the stability of the installation.

[0012] In the above-mentioned motor end cover of a sewing machine, one of the bosses is arranged in the middle of the first side, and the other two bosses are arranged opposite to each other.

[0013] One boss is located in the middle of the side one, and the other two bosses are arranged opposite to each other. This structure makes the force on the motor end cover more balanced after installation, and further improves the stability of the installation.

[0014] In the above-mentioned motor end cover of a sewing machine, one side and the other side of the boss on the side one are respectively provided with reinforcing ribs, and the reinforcing ribs are connected to the side one.

[0015] The reinforcing ribs increase the connection strength between the boss and the housing, and also increase the strength of the entire motor end cover.

[0016] In the above-mentioned motor end cover of a sewing machine, the boss arranged at the connection between the second side and the third side has two connected side walls, and the side walls are distributed on the second side and the third side.

[0017] The boss is formed by removing material from the second side and the third side. This structure saves material, and the screw will not protrude from the shell after being passed through the boss, thus saving space.

[0018] In the above-mentioned motor end cover of a sewing machine, the boss arranged at the connection between the side three and the side four has two connected side walls, and the side walls are distributed on the side three and the side four.

[0019] The boss is formed by removing material from the side three and the side four. This structure saves material, and the screw will not protrude from the shell after being passed through the boss, thus saving space.

[0020] In the above-mentioned motor end cover of a sewing machine, the housing is provided with a clearance hole through which the main shaft of the power supply motor passes.

[0021] The utility model also provides a connection structure between a motor end cover and a motor, the connection structure comprising a motor and any one of the above motor end covers, the motor being mounted on a shell of the motor end cover, and a boss on the shell extending from the outside of the motor.

[0022] After the motor is installed on the housing of the motor end cover, each boss extends out from the outside of the motor, which can prevent the motor from interfering with the housing during installation and improve the convenience of installation.

[0023] Compared with the prior art, the advantages of the utility model are as follows:

[0024] The shell of the motor end cover is provided with a mounting structure, and no additional fixing frame is required. The end cover can be directly mounted on the shell, which greatly improves the convenience of installation, simplifies the mounting structure, and saves manufacturing costs.

Bosses 2 are arranged on the four sides of the shell 1. After screws are passed through the bosses 2 and threadedly connected to the casing, the force on the motor end cover is more balanced, which greatly improves the stability of the installation.

[0035] like Figure 1 As shown, in this embodiment, one boss 2 is arranged in the middle of the side 1 4, and the other two bosses 2 are arranged opposite to each other.

[0036] One boss 2 is located in the middle of the side 4, and the other two bosses 2 are arranged opposite to each other. This structure makes the force on the motor end cover more balanced after installation, and further improves the stability of the installation.

[0037] like Figure 1 As shown, in this embodiment, one side and the other side of the boss 2 on the side 1 4 are respectively provided with reinforcing ribs 8 , and the reinforcing ribs 8 are connected to the side 1 4 .

[0038] The reinforcing ribs 8 increase the connection strength between the boss 2 and the housing 1 , and also increase the strength of the entire motor end cover.

[0039] like Figure 1 As shown, in this embodiment, the boss 2 arranged at the connection between the second side 5 and the third side 6 has two connected side walls 9, and the side walls 9 are distributed on the second side 5 and the third side 6.

[0040] The boss 2 is formed by removing materials from the second side 5 and the third side 6. This structure saves materials, and the screws will not protrude from the housing 1 after being passed through the boss 2, thus saving space.

[0041] like Figure 2 As shown, in this embodiment, the boss 2 arranged at the connection between the side three 6 and the side four 7 has two connected side walls 9, and the side walls 9 are distributed on the side four 7 and the side three 6.

[0042] The boss 2 is formed by removing material from the side three 6 and the side four 7. This structure saves material, and the screws will not protrude from the housing 1 after being passed through the boss 2, thus saving space.

[0043] like Figure 1 As shown, in this embodiment, the housing 1 is provided with a clearance hole 10 through which the main shaft of the power supply machine 11 passes.

[0044] like Figure 3As shown, the utility model also provides a connection structure between a motor end cover and a motor 11 , the connection structure comprising a motor 11 and any one of the above-mentioned motor end covers, the motor 11 being mounted on a housing 1 of the motor end cover, and a boss 2 on the housing 1 extending from the outside of the motor 11 .

[0045] After the motor 11 is installed on the housing 1 of the motor end cover, each boss 2 extends out from the outside of the motor 11, which can prevent the motor 11 from interfering with the housing during installation, thereby improving the convenience of installation.

[0046] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
