Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harnesses, in particular to a left front A-pillar wire protection box. Background Art

[0002] In the design of automotive wiring harnesses, it is often encountered that many wiring harnesses need to be fixed, especially the low-voltage wiring harnesses of the entire vehicle. Due to 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 a wiring harness protection box that meets its functions to solve the problem.

[0003] Normally, the space under the left front A-pillar is very limited, and the wiring harness is thick and complicated to assemble. After assembly, the wiring harness will be twisted and arched. During driving, the vibration of the car will cause friction and abnormal noise between the wiring harness and surrounding parts (between the wiring harness and the car body, or between the wiring harnesses). Utility Model Content

[0008] Preferably, three mounting slots are provided, and the three mounting slots are connected together.

[0009] Preferably, the fixing hole is fixed to the vehicle body sheet metal below the left front A-pillar via a nut.

[0010] Preferably, the surface of the wire protection box body is integrally connected with reinforcing ribs.

[0011] Preferably, the reinforcing ribs are arranged in a crisscross pattern.

[0012] Preferably, a convex strip is fixedly mounted on the wire protection box body, and a fixing hole is provided on the convex strip.

[0013] Preferably, the convex strips are arranged obliquely.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model is fixed on the vehicle body sheet metal below the left front A-pillar, is easy to assemble and reliably fixed, and the cables can be fixed thereon with cable ties to prevent wear and abnormal noise caused by bowing and interference with surrounding parts, thereby ensuring the reasonable arrangement and reliable fixation of the wiring harness.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 As shown, this embodiment provides a left front A-pillar wire protection box, including a wire protection box body 1, and three cable installation grooves connected in one piece are respectively provided on the upper surface of the wire protection box body 1. The ends of the three cable installation grooves intersect together to form a cable installation portion. The low-voltage wiring harness cable of the automobile is directly placed in the installation groove and arranged in the installation groove, and the cable is wrapped inside the installation groove. Since the wiring harness under the left front A-pillar is thicker, the installation groove is specially used to carry the wiring harness or cable, and limit the wiring harness or cable, which can reduce the problem of the wiring harness or cable bowing and ensure the installation quality of the wiring harness.

[0021] The upper surface of the wire protection box body 1 is provided with a mounting hole 2, which is used to fix the wire harness tie to install the low-voltage wire harness and the wire protection box body 1 together. Figure 1 As shown, multiple mounting holes 2 are provided. After the low-voltage wiring harness is placed in the mounting slot, a wiring harness tie is inserted into the mounting hole 2 to confine the low-voltage wiring harness in the mounting slot, thereby installing the low-voltage wiring harness together with the wire protection box body 1. The wiring harness tie acts as a position limiter, preventing the wiring harness from bowing or twisting, thereby reducing or resolving the problem of wiring harness twisting and bowing caused by the thick wiring harness below the A-pillar.

[0022] like Figure 3As shown, since the wiring harness installed under the left front A-pillar is thicker, after the thicker wiring harness is installed inside the wire protection box body 1, it will bend itself, which will cause the wire protection box body 1 to deform along with the bent wiring harness. Therefore, in this embodiment, the surface of the wire protection box body 1 is also provided with criss-cross reinforcing ribs 5. The reinforcing ribs 5 are generally provided at the corners of the wire protection box body 1 and are integrally formed with the wire protection box body 1, which can reduce the production cost and processing technology. In addition, the reinforcing ribs 5 provided at the corners will not take up additional space, and the surface of the wire protection box body 1 remains smooth, which makes it convenient to place the wiring harness into the placement groove. The reinforcing ribs 5 can increase the strength of the wire protection box body 1, avoid the wire protection box body 1 from deforming along with the wiring harness, and improve the installation quality of the wiring harness.

[0023] The wire protection box body 1 is fixed with two convex strips protruding outwards, and the two convex strips are respectively provided with fixing holes 3 and 4. Figure 1 and Figure 2 As shown, the two convex strips are arranged at an angle and match the body sheet metal below the left front A-pillar. When installing, insert the bolts into the fixing holes 3 and 4, and fix the wire protection box body 1 to the body sheet metal below the left front A-pillar with nuts to complete the installation of the wire protection box body 1. The bolts can be used to install the wire protection box body 1 on the body, which is easy to assemble and reliable.

[0024] Fixing the wire protection box body 1 to the vehicle body sheet metal under the left front A-pillar, and placing the wiring harness in the placement groove of the wire protection box body 1, the wire harness and the vehicle body sheet metal can be fixed as one, which can avoid the bowing and twisting of the wire harness, reduce or prevent the wear and abnormal noise caused by the interference between the bowed wire harness and the surrounding parts, and ensure the reasonable arrangement and reliable fixation of the wire harness.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
