[0037] In addition, in the description of the utility model, unless otherwise stated, the meaning of "multiple" is two or more than two.

[0038] For ordinary skilled in the art, the above terms can be understood in the utility model according to specific circumstances.

[0039] Please refer to Figure 3 The utility model discloses a connecting structure of the elevator motor 2 and the wire winding wheel cover 1 of a car, which comprises a wire winding wheel cover 1, an elevator motor 2, a connecting nut 3 and a connecting bolt 4.

[0040] The wire winding wheel cover 1 has a first mounting hole 11.

[0041] The elevator motor 2 has a second mounting hole 21 coaxial with the first mounting hole 11.

[0042] The connecting nut 3 is at least partially embedded in the wire winding wheel cover 1, and is located on the inner wall of the first mounting hole 11.

[0043] The connecting bolt 4 is threaded through the second mounting hole 21 and the first mounting hole 11, and is screwed with the connecting nut 3.

[0044] The connecting structure of the elevator motor 2 and the wire winding wheel cover 1 of the car of the utility model embeds the connecting nut 3 in the wire winding wheel cover 1, without the need to separately fix the position of the connecting nut 3, reducing the number of parts that need to be fixed, and simplifying the operation process, reducing the operation time and reducing the rate of assembly failure when operating. Moreover, at least a part of the connecting nut 3 is embedded in the wire winding wheel cover 1, which can also reduce the occupation of the connecting nut 3 to the external space. In addition, since the connecting nut 3 is equivalent to being integrated on the wire winding wheel cover 1, the manufacturing tolerance accumulation is reduced, and the cost of procurement management is reduced.

[0045] Specifically, the connecting bolt 4 is equivalent to an insert, which can be made of injection molding together with the wire winding wheel cover 1.

[0046] In some embodiments, the connecting bolt 4 comprises a head 41 and a first columnar portion 42, the head 41 is arranged at one end of the first columnar portion 42, the first columnar portion 42 is provided with threads matched with the connecting nut 3, the first columnar portion 42 penetrates the second mounting hole 21 and the first mounting hole 11, and the head 41 is located at the side of the lifter motor 2 away from the yarn winding wheel cover 1. The connecting bolt 4 is connected with the connecting nut 3 through the threads on the first columnar portion 42, and the head 41 can be pressed on the lifter motor 2, so that the lifter motor 2 is pressed on the yarn winding wheel cover 1, realizing the connection between the lifter motor 2 and the yarn winding wheel cover 1.

[0048] The arrangement of the second columnar portion 43 can improve the connection stability of the connecting bolt 4 and the connecting nut 3 after they are connected, reduce the tightening torque attenuation of the connecting nut 3, and avoid the axial jump of the yarn winding wheel cover 1 leading to the failure of the lifter.

[0049] An end of the second columnar portion 43 away from the head 41 is provided with a clamping portion 431.

[0050] When machining the threads on the first columnar portion 42, the position of the first columnar portion 42 can be limited by fixing the clamping portion 431 to machine the threads.

[0051] The edge of the head 41 is smoothly transitioned. Through such a structure, the operator can be protected from being injured by the sharp edge.

[0052] The connecting bolt 4 protrudes from the end face of the connecting nut 3 away from the lifter motor 2, which can ensure the engagement degree between the connecting bolt 4 and the connecting nut 3, thereby ensuring the connection stability.

[0053] The end face of the connecting nut 3 away from the lifter motor 2 is flush with the end face of the yarn winding wheel cover 1 away from the lifter motor 2.

[0054] In this way, the connecting nut 3 is equivalent to being completely embedded in the yarn winding wheel cover 1, and the connecting nut 3 will not occupy external space, nor will it harm the operator due to its sharp edge.

[0055] A groove 31 is arranged on the outer circumferential surface of the connecting nut 3, and the groove wall of the groove 31 is in contact with the yarn winding wheel cover 1.

[0056] The arrangement of the groove 31 can increase the contact area between the yarn winding wheel cover 1 and the connecting nut 3, and improve the firmness of the connecting nut 3 in the yarn winding wheel cover 1.

[0057] The first limiting part 12 is arranged on the winding wheel cover 1, and the second limiting part 22 corresponding to the first limiting part 12 is arranged on the elevator motor 2, and the first limiting part 12 and the second limiting part 22 match each other to limit the relative position of the elevator motor 2 and the winding wheel cover 1.

[0058] The first limiting part 12 on the winding wheel cover 1 is arranged around the first mounting hole 11 and forms a protrusion shape, and the second limiting part 22 on the elevator motor 2 is arranged around the second mounting hole 21 and forms a groove shape, the protrusion is inserted into the groove, that is, the first limiting part 12 is inserted into the second limiting part 22, so as to limit the relative position of the elevator motor 2 and the winding wheel cover 1.

[0059] The embodiment also provides an automobile comprising the connecting structure of the elevator motor 2 and the winding wheel cover 1, and the position of the separate fixing connecting nut 3 is not needed, the number of parts needing to be fixed is reduced, the operation process can be simplified, the operation time is reduced, and the assembly failure rate is reduced.

[0060] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
