DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] In the description of the present application, it should be understood that the terms "inside", "outside", "upper", "lower", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "multiple" means two or more, and at least one means one, two or more than two, unless otherwise clearly and specifically defined. "Connection" can be a direct connection, that is, one object is directly connected to another object in contact, or an indirect connection, that is, one object is connected to another object through other objects.

[0044] It should also be noted that in the drawings of the present application specification, an arrow marked with X indicates a first direction X, and an arrow marked with Y indicates a second direction Y. The first direction X and the second direction Y are introduced to facilitate the clear description of the shape, structure and relative position relationship of the components of the wiring harness protection member in the embodiment of the present application. The first direction X and the second direction Y are both relative directions, not absolute directions. It is understandable that in actual implementation, the first direction X and the second direction Y can point to any direction, as long as the first direction X and the second direction Y intersect. Preferably, the first direction X and the second direction Y are perpendicular.

[0045] The applicant has noticed that the diameter of the sheet metal hole 710 through which the automobile wiring harness passes is currently different, or the thickness of the sheet metal 700 passed through is also different. Therefore, it is necessary to develop rubber parts that are adapted to different sheet metal hole 710 diameters or sheet metal 700 thicknesses to protect the wiring harness, which increases the number of newly developed automobile parts and increases development costs.

[0046] In view of this, an embodiment of the present application provides a wire harness protector to overcome at least one of the above technical defects.

[0047] Please also read Figures 1 to 5 The wire harness protection member of the embodiment of the present application includes a body 100 , a first flange 200 , a second flange 300 and a third flange 400 .

[0048] The body 100 has a threading channel 110 that is arranged along the first direction X, and the automotive wiring harness can be arranged in the threading channel 110. The first flange 200, the second flange 300, and the third flange 400 are all connected around the outer periphery of the body 100, that is, the first flange 200, the second flange 300 and the third flange 400 are an annular flange structure arranged circumferentially of the body 100. The first flange 200 and the third flange 400 are respectively arranged on 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 along the first direction X to form a first annular groove 500, and the third flange 400 and the second flange 300 are spaced along the first direction X to form a second annular groove 600. In other words, the surfaces of the first flange 200 and the second flange 300 facing each other form the opposite side walls of the first annular groove 500, and the outer peripheral surface of the body 100 forms the bottom wall of the first annular groove 500; the surfaces of the third flange 400 and the second flange 300 facing each other form the opposite side walls of the second annular groove 600, and the outer peripheral surface of the body 100 forms the bottom wall of the second annular groove 600. The size of the first annular groove 500 is different from that of the second annular groove 600.

[0049] It can be understood that the wiring harness protector forms a first ring groove 500 and a second ring groove 600 by arranging a first flange 200, a second flange 300 and a third flange 400 on the main body 100, and the sizes of the first ring groove 500 and the second ring groove 600 are different. Therefore, the first ring groove 500 and the second ring groove 600 can match different sheet metal 700 thicknesses or sheet metal hole 710 diameters, and can adapt to two different vehicle body sheet metal 700 usage environments, thereby improving the adaptability of spare parts, reducing the number of spare parts, reducing development costs, and also facilitating parts management.

[0050] Please combine Figure 8 and Fig. 9 In some embodiments, the first annular groove 500 has a first dimension h along the first direction X, where h is the width of the first annular groove 500, and the dimension determines the thickness of the thickest sheet metal 700 that the first annular groove 500 can adapt to. The second annular groove 600 has a second dimension H along the first direction X, where H is the width of the second annular groove 600, and the dimension determines the thickness of the thickest sheet metal 700 that the second annular groove 600 can adapt to. The first dimension h and the second dimension H satisfy: H>h, or, H<h. In other words, the width of the first annular groove 500 can be greater than the width of the second annular groove 600, or it can be less than the width of the second annular groove 600. By setting the widths of the first annular groove 500 and the second annular groove 600 differently, sheet metals 700 of different thicknesses can be adapted, thereby satisfying the assembly environment of two sheet metals 700 of different thicknesses. Exemplarily, the first dimension h may be 0.8 mm, and the second dimension H may be 1.2 mm; or, the first dimension h may be 1.2 mm, and the second dimension H may be 0.8 mm. The first dimension h and the second dimension H may be set according to actual needs and are not particularly limited herein.

[0051] It should be noted that, in some embodiments, the width of the first annular groove 500 may be consistent with the width of the second annular groove 600, that is, the first annular groove 500 and the second annular groove 600 can be adapted to the sheet metal 700 of the same thickness. By setting the other dimensions of the first annular groove 500 and the second annular groove 600 differently, adaptability to different installation environments of the sheet metal 700 can be achieved.

[0052] Please refer again Figure 8In some embodiments, the first annular groove 500 has a third dimension d along the second direction Y, which is the diameter of the first annular groove 500, that is, the bottom wall diameter of the first annular groove 500, and the dimension determines the diameter of the sheet metal hole 710 that the first annular groove 500 can adapt to. The second annular groove 600 has a fourth dimension D along the second direction Y, which is the diameter of the second annular groove 600, that is, the bottom wall diameter of the second annular groove 600, and the dimension determines the diameter of the sheet metal hole 710 that the second annular groove 600 can adapt to. The third dimension d and the fourth dimension D satisfy: D>d, or, D<d. That is, the diameter of the first annular groove 500 can be greater than the diameter of the second annular groove 600, or it can be less than the diameter of the second annular groove 600. By setting the diameters of the first annular groove 500 and the second annular groove 600 differently, different diameters of the sheet metal holes 710 can be adapted, thereby satisfying the sheet metal 700 assembly environment of two sheet metal hole 710 diameters. Exemplarily, the third dimension d may be 50 mm, and the fourth dimension D may be 70 mm; or, the third dimension d may be 70 mm, and the fourth dimension D may be 50 mm. The third dimension d and the fourth dimension D may be set according to actual needs and are not particularly limited herein.

[0053] See also Figure 6 In some embodiments, the threading channel 110 includes a threading hole 111 and a buffer cavity 112 that are interconnected, and the automotive wiring harness is sequentially threaded through the threading hole 111 and the buffer cavity 112, and the diameter r of the threading hole 111 is smaller than the diameter R of the buffer cavity 112. The body 100 includes a threading portion 120 and a support portion 130 that are connected to each other, the threading hole 111 is formed in the threading portion 120, and the buffer cavity 112 is formed in the support portion 130. The first flange 200, the second flange 300, and the third flange 400 are connected to the outer periphery of the support portion 130. When the wiring harness protector is installed into the sheet metal hole 710, the sheet metal 700 is inserted into the first annular groove 500 between the first flange 200 and the second flange 300, or inserted into the second annular groove 600 between the third flange 400 and the second flange 300. In this process, the hole wall of the sheet metal hole 710 may squeeze the first flange 200 or the third flange 400, and then squeeze the support part 130, so that the support part 130 is deformed to achieve the installation of the wire harness protection component into the sheet metal hole 710, or the hole wall of the sheet metal hole 710 may squeeze the bottom wall of the first annular groove 500 or the second annular groove 600, so that the support part 130 is deformed to a certain extent. By setting the diameter R of the buffer cavity 112 formed in the support part 130 to be larger than the diameter r of the threading hole 111, the threading space inside the buffer cavity 112 can be guaranteed, and the wire harness can be prevented from being squeezed due to the deformation of the support part 130, thereby improving the protection of the wire harness.

[0054] Further, please combine Figure 3 and Figure 6In some embodiments, the body 100 further includes a buffer portion 140, which is connected between the threading portion 120 and the support portion 130. The buffer portion 140 is recessed from the edge of the support portion 130 toward the buffer cavity 112 and extends to the threading portion 120, and the threading portion 120 extends from the buffer portion 140 in a direction away from the buffer cavity 112. The threading portion 120 and the support portion 130 are connected by the buffer portion 140 to form a bending buffer structure. When the support portion 130 is squeezed and deformed, the buffer portion 140 forms a certain buffer space to avoid excessive force transmission to the threading portion 120 and excessive deformation of the threading portion 120, thereby avoiding squeezing of the wire harness in the threading hole 111, so that the protection is more sufficient. In addition, the special structure composed of the threading portion 120, the support portion 130 and the buffer portion 140 can also improve the elastic deformation capacity of the wire harness protection component to a certain extent, making the assembly more convenient and the installation more firm, and also improving the sealing performance.

[0055] Please also read Figure 6 and Figure 7 In some embodiments, the first flange 200 includes a first guide bevel 210, and the first guide bevel 210 is inclined relative to the first direction X; the first guide bevel 210 is connected to the inner wall of the first annular groove 500 to guide the wiring harness protection component into the first annular groove 500, so as to facilitate the smooth installation of the wiring harness protection component into the corresponding sheet metal hole 710. It should be noted that the first guide bevel 210 is the outer peripheral surface of the first flange 200, and the inner wall of the first annular groove 500 includes two side walls arranged opposite to each other and a bottom wall connected between the two side walls, and the first guide bevel 210 is connected to one of the side walls. Since the first guide bevel 210 is inclined relative to the first direction X, when the wiring harness protection component is installed into the sheet metal hole 710 adapted to the first annular groove 500, the first guide bevel 210 can cooperate with the hole wall of the sheet metal hole 710 to guide the installation, so as to facilitate the smooth installation of the wiring harness protection component into the sheet metal hole 710. For details, please refer to Fig.10 The wiring harness protection component can be pushed into the sheet metal hole 710 along the first direction X to achieve assembly.

[0056] Correspondingly, in some embodiments, the third flange 400 includes a second guide bevel 410, and the second guide bevel 410 is inclined relative to the first direction X; the second guide bevel 410 is connected to the inner wall of the second annular groove 600 to guide it into the second annular groove 600, so as to facilitate the smooth installation of the wiring harness protection component into the corresponding sheet metal hole 710. It should be noted that the second guide bevel 410 is the outer peripheral surface of the third flange 400, and the inner wall of the second annular groove 600 includes two side walls arranged opposite to each other and a bottom wall connected between the two side walls, and the second guide bevel 410 is connected to one of the side walls. Since the second guide bevel 410 is inclined relative to the first direction X, when the wiring harness protection component is installed into the sheet metal hole 710 adapted to the second annular groove 600, the second guide bevel 410 can cooperate with the hole wall of the sheet metal hole 710 to guide the installation, so as to facilitate the smooth installation of the wiring harness protection component into the sheet metal hole 710. Please refer to Fig.11 The wiring harness protection component can be pulled into the sheet metal hole 710 along the opposite direction of the first direction X to achieve assembly.

[0057] Please refer again Figure 7 In some embodiments, the second flange 300 includes a main body 310, a first boss 320, and a second boss 330. The main body 310 is connected to the outer periphery of the body 100, the first boss 320 is connected to the main body 310, and is protruded relative to the main body 310 toward the first flange 200 along the first direction X; the second boss 330 is connected to the main body 310, and is protruded relative to the main body 310 toward the second flange 300 along the opposite direction of the first direction X. By arranging the first boss 320 on the side of the main body 310 facing the first flange 200, when the sheet metal 700 is inserted into the first annular groove 500, the first boss 320 can be pressed against the sheet metal 700, and the pressing force can be used to improve the stability and sealing of the assembly. Similarly, by providing a second boss 330 on the side of the main body 310 facing the third flange 400, when the sheet metal 700 is inserted into the second annular groove 600, the second boss 330 can be pressed against the sheet metal 700, thereby improving the stability and sealing of the assembly by using the pressing force.

[0058] Specifically, in some embodiments, the first boss 320 surrounds the body 100 and is spaced apart from the body 100; the second boss 330 surrounds the body 100 and is spaced apart from the body 100. That is, the first boss 320 is spaced apart from the bottom wall of the first annular groove 500, and the first boss 320 is in a complete ring shape around the body 100, which can further improve the installation stability of the sheet metal 700 inserted into the first annular groove 500, and the sealing performance between the wire harness protection component and the sheet metal 700. Similarly, the second boss 330 is spaced apart from the bottom wall of the second annular groove 600, and the second boss 330 is in a complete ring shape around the body 100, which can further improve the installation stability of the sheet metal 700 inserted into the second annular groove 600, and the sealing performance between the wire harness protection component and the sheet metal 700.

[0059] Specifically, in the above embodiment, the main body 310, the first boss 320 and the second boss 330 may be an integrally formed structure, that is, the second flange 300 is an integrally formed structure, which facilitates manufacturing and improves the overall stability of the structure.

[0060] Furthermore, the main body 100 and at least one of the first flange 200, the second flange 300, and the third flange 400 are an integrally formed structure. For example, the main body 100 and the first flange 200 are an integrally formed structure, and the other two are an assembled structure; or the main body 100 and the second flange 300 are an integrally formed structure, and the other two are assembled structures; or the main body 100 and the third flange 400 are an integrally formed structure, and the other two are assembled structures. Alternatively, the main body 100 and any two of the first flange 200, the second flange 300, and the third flange 400 are an integrally formed structure, and the other one is an assembled structure. Alternatively, the main body 100 and the first flange 200, the second flange 300, and the third flange 400 are an integrally formed structure, that is, the wiring harness protection component is integrally formed as a whole, which is convenient for manufacturing and improves the overall stability of the structure.

[0061] Specifically, in some embodiments, the wire harness protection piece is made of elastic material, such as rubber material, polymer material, elastic plastic, etc. The processing cost is low, the installation is easy, and the stability and sealing after installation can be guaranteed.

[0062] In addition, in some embodiments, a fourth flange may be arranged at intervals on the side of the first flange 200 away from the second flange 300 or the side of the third flange 400 away from the second flange 300 to form a third annular groove (not shown), and the size of the third annular groove may be set different from the first annular groove 500 and the second annular groove 600 to further improve the adaptability. Specifically, the number of flange structures may be selectively set according to actual needs and the limitation of the sheet metal installation space to form multiple annular grooves that meet the sheet metal hole adaptation requirements to improve the adaptability.

[0063] The harness protector is mainly used to protect the automotive harness from being damaged by the sharp edges of the sheet metal 700. In addition, it is also used to protect the automotive harness from damage from other external environments, such as water, dust, chemicals and mechanical wear. It can also provide additional insulation, shock absorption, buffering and other protection to ensure the safe operation of the harness.

It is understandable that the car includes the above wiring harness protection member, and thus can have all the technical features and technical effects of the above wiring harness protection member, which will not be repeated here.
