In summary, according to the pull wire bushing fixing assembly 100 of the embodiment of the present utility model, the elastic clamping portion 30 is provided on one of the inner wall surface of the mounting hole 11 and the outer circumferential surface of the bushing fixing head 20, the mating portion 12 is provided on the other of the inner wall surface of the mounting hole 11 and the bushing fixing head 20, and when the bushing fixing head 20 is inserted into the mounting hole 11 during mounting, after the bushing fixing head 20 is inserted into the set position, the elastic clamping portion 30 automatically cooperates with the mating portion 12 to fix the bushing fixing head 20, so that the operation is simple and the mounting is convenient; and because the elastic clamping part 30 can generate certain elastic deformation, the precision requirements on the mounting hole 11 and the matching part 12 are lower, and the production and the processing are convenient.

The embodiment of the utility model also provides a vehicle door, which comprises the stay wire bushing fixing assembly 100 described in any embodiment, further comprises a stay wire 200, a bushing 210 and a zipper head 220, wherein the bushing fixing head 20 is arranged at one end of the bushing 220, one end of the stay wire 200 passes through the bushing 210 and the bushing fixing head 20 to be connected with the zipper head 220, and the zipper head 220 is connected with a door lock of the vehicle door. Since the wire-drawing bushing fixing assembly 100 according to the embodiment of the utility model can solve the problem that the conventional wire-drawing bushing fixing assembly is inconvenient to assemble, the vehicle door of the embodiment of the utility model also has the advantage of being convenient to assemble, and the embodiment is not repeated.

Embodiments of the present utility model also provide a vehicle including the wire bushing securing assembly 100 described in any of the above embodiments or the vehicle door described in any of the above embodiments.

While certain specific embodiments of the utility model have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the utility model. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
