In view of the above, embodiments of the present application provide a wire harness protection member for overcoming at least one of the above technical drawbacks.

Referring to fig. 1 to 5, the wire harness protector according to the embodiment of the application includes a body 100, a first flange 200, a second flange 300, and a third flange 400.

The body 100 has a threading channel 110 penetrating along a first direction X, and the automobile wire harness may be threaded through the threading channel 110. The first flange 200, the second flange 300, and the third flange 400 are all circumferentially connected to the outer circumference of the body 100, that is, the first flange 200, the second flange 300, and the third flange 400 are annular flange structures circumferentially disposed on the body 100. The first flange 200 and the third flange 400 are respectively disposed at both sides of the second flange 300 along the first direction X, and the second flange 300 is located between the first flange 200 and the third flange 400. The first flange 200 and the second flange 300 are spaced apart in the first direction X to form a first ring groove 500, and the third flange 400 and the second flange 300 are spaced apart in the first direction X to form a second ring groove 600.

The second ring groove 600 has a second dimension H along the first direction X, H being the width of the second ring groove 600, which determines the thickness of the thickest sheet metal 700 that the second ring groove 600 can fit. The first dimension H and the second dimension H satisfy: h > H, or H < H. That is, the width of the first ring groove 500 may be greater than the width of the second ring groove 600, or may be smaller than the width of the second ring groove 600, and by setting the widths of the first ring groove 500 and the second ring groove 600 different, the metal plate 700 with different thickness may be adapted, so as to satisfy the assembly environment of the metal plates 700 with two different thicknesses. Illustratively, the first dimension H may be 0.8mm and the second dimension H may be 1.2mm; or the first dimension H may be 1.2mm, the second dimension H may be 0.8mm, and the first dimension H and the second dimension H may be specifically set according to actual needs, and are not particularly limited herein.

It should be noted that, in some embodiments, the width of the first ring groove 500 may be identical to the width of the second ring groove 600, that is, the first ring groove 500 and the second ring groove 600 can adapt to the sheet metal 700 with the same thickness. The adaptability to the installation environments of different metal plates 700 can be achieved by setting the other sizes of the first ring groove 500 and the second ring groove 600 to be different.

The second ring groove 600 has a fourth dimension D along the second direction Y, where the fourth dimension D is the diameter of the second ring groove 600, that is, the bottom wall diameter of the second ring groove 600, and the dimension determines the diameter of the sheet metal hole 710 that the second ring groove 600 can fit. The third dimension D and the fourth dimension D satisfy: d > D, or D < D. That is, the diameter of the first ring groove 500 may be larger than the diameter of the second ring groove 600, or may be smaller than the diameter of the second ring groove 600, and by setting the diameters of the first ring groove 500 and the second ring groove 600 different, the diameters of the sheet metal holes 710 may be adapted, so as to satisfy the assembly environments of the sheet metal 700 with the diameters of the two sheet metal holes 710. Illustratively, the third dimension D may be 50mm and the fourth dimension D may be 70mm; or the third dimension D may be 70mm, the fourth dimension D may be 50mm, and the third dimension D and the fourth dimension D may be specifically set according to actual needs, and are not particularly limited herein.
