Abstract
Description
Technical Field
[0001] The utility model relates to a wire protection box. Background Art
[0002] In the design of automotive wiring harnesses, we often encounter many wiring harness directions that need to be fixed, especially high-voltage wiring harnesses. Because of their large wire diameter and high hardness, they are not easy to bend. In terms of safety, the cables need to be protected. Therefore, it is necessary to design and develop wiring harness protection boxes that meet their functions to solve the problem.
[0003] However, usually, the space on the inner plate of the wheel housing is very limited, and the assembly is relatively complicated, which will cause the risk of the harness being worn. In order to protect the high-voltage harness, the harness box needs to be arranged along the direction of the high-voltage harness, but the space on the inner plate of the wheel housing is very limited, and there are few fixing points. How to keep the harness box firmly fixed while meeting the direction of the harness is a problem that the utility model needs to solve. At the same time, in order to firmly fix the harness in the prior art, the harness and the wire protection box are generally firmly fixed together. In this way, when the harness shrinks and expands due to temperature changes, there is no elastic space, which will cause abnormal noise. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the utility model provides a high-voltage wire harness protection box, which can fix the wire harness and can complete the fixation through as few fixing points as possible in the limited space on the inner plate of the wheel arch without affecting the direction of the high-voltage wire harness. At the same time, a split design is adopted to provide space for the shrinkage and expansion of the wire harness and reduce abnormal noise.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A high-voltage wire harness protection box comprises a first segment and a second segment fixed at intervals, wherein the first segment and the second segment both comprise a bottom plate and side walls located on both sides of the bottom plate, wherein the bottom plate and the side walls are combined to form a wire harness groove for accommodating the high-voltage wire harness, wherein a plurality of groups of wire harness tie fixing holes are evenly distributed on the bottom plate along the length direction of the bottom plate, and each group of wire harness tie fixing holes consists of two hollow holes maintained at a fixed distance.
[0007] The first segment includes a straight line segment and an arc segment, wherein the side walls on both sides of the straight line segment are straight lines, and the side walls on both sides of the arc segment are arcs. A fixing plate is respectively provided on the two side walls of the straight line segment, and a fixing plate is provided on the side wall of the arc segment located on the inner arc side.
[0008] The fixing plates on the two side walls of the straight section, one of which is arranged at the outermost end of the straight section, and the other is arranged in the middle of the straight section.
[0009] The side walls on both sides of the second segment are arc-shaped, a fixing plate is arranged on the side wall of the second segment located at the outer arc, and a fixing plate is arranged on the side wall of the second segment located at the inner arc.
[0010] The straight line segment and the arc segment of the first segment are integrally formed.
[0011] A bolt hole is arranged in the center of the fixing plate.
[0012] The bottom plate is provided with longitudinal reinforcing ribs extending along the length direction of the bottom plate.
[0013] A plurality of transverse reinforcing ribs are evenly distributed on the bottom plate along the length direction of the longitudinal reinforcing ribs.
[0014] The transverse reinforcing ribs are perpendicular to the longitudinal reinforcing ribs.
[0015] The transverse reinforcing ribs and the longitudinal reinforcing ribs are both convex strips protruding upward from the bottom plate.
[0016] The beneficial effects of the utility model are:
[0017] 1) The limited space on the inner panel of the wheel housing is fixed by as few fixing points as possible, and the direction of the high-voltage wiring harness is not affected;
[0018] 2) The split design provides space for the shrinkage and expansion of the wiring harness and reduces abnormal noise. BRIEF DESCRIPTION OF THE DRAWINGS
[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.
[0026] like Figure 1As shown, the utility model provides a high-voltage wire harness protection box, including a first segment 100 and a second segment 200 fixed at intervals, the first segment 100 and the second segment 200 both include a bottom plate 101 and side walls 102 located on both sides of the bottom plate, the bottom plate 101 and the side walls 102 are combined to form a wire harness groove for accommodating the high-voltage wire harness, and a plurality of groups of wire harness tie fixing holes 106 are evenly distributed on the bottom plate 101 along the length direction of the bottom plate, and each group of wire harness tie fixing holes 106 consists of two hollow holes maintained at a fixed distance.
[0027] When in use, the first section 100 and the second section 200 are fixed on the inner plate of the wheel housing respectively, leaving a certain space between them, and then the high-voltage wire harness is placed into the wire harness groove along the extension direction of the first section 100 and the second section 200, and fixed with a wire harness tie.
[0028] Since the wire protection box is divided into two parts, when the wire harness shrinks or expands, the space between the two parts can provide room for the shrinkage or expansion of the wire harness, thereby avoiding abnormal noise caused by the extrusion of the wire harness.
[0029] The first segment 100 includes a straight line segment 110 and an arc segment 120, wherein the side walls on both sides of the straight line segment 110 are straight lines, the side walls on both sides of the arc segment 120 are arcs, a fixing piece 105 is respectively disposed on the two side walls of the straight line segment 110, and a fixing piece 105 is disposed on the side wall of the arc segment 120 located on the inner arc side. Of the fixing pieces 105 on the two side walls of the straight line segment 110, one fixing piece 105 is disposed at the outermost end of the straight line segment 110, and the other is disposed in the middle of the straight line segment 110.
[0030] The side walls on both sides of the second segment 200 are arc-shaped. A fixing plate 105 is provided on the side wall of the second segment 200 located at the outer arc, and a fixing plate 105 is provided on the side wall of the second segment 200 located at the inner arc.
[0031] The straight line segment 110 and the arc segment 120 of the first segment 100 are integrally formed.
[0032] A bolt hole is provided in the center of the fixing plate 105 , and the first section 100 and the second section 200 can be fixed to the inner plate of the wheel housing by passing bolts through the bolt hole in the center of the fixing plate 105 .
[0033] Three fixing plates 105 are arranged on both sides of the first segment 100 to fix the first segment, and only two fixing plates 105 are arranged on the second segment 200. In addition, the two fixing plates can complete the fixing of the second segment due to the restraining effect of the wire harness.
[0034] The special shape adopted by the utility model can realize fixation with a minimum number of fixing points, which is precious in the limited space of the inner plate of the wheel cover.
[0035] In order to improve the strength of the wire protection box, the bottom plate 101 is provided with longitudinal reinforcing ribs 103 extending along the length direction of the bottom plate 101, and the bottom plate 101 is evenly distributed with a plurality of transverse reinforcing ribs 104 along the length direction of the longitudinal reinforcing ribs 103, and the transverse reinforcing ribs 104 are perpendicular to the longitudinal reinforcing ribs 103. Both the transverse reinforcing ribs 103 and the longitudinal reinforcing ribs 104 are convex strips protruding upward from the bottom plate.
