Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to a wiring harness protection box for an automobile chassis. Background Art

[0002] The automotive wiring harness is one of the important components of the automotive electrical part. It is used to connect the electrical components of the entire vehicle and has the functions of transmitting electrical energy and communication. The wiring harness near the chassis of the car is called the chassis wiring harness. Since the chassis wiring harness is set on the chassis of the car, the chassis wiring harness is more easily damaged during the use of the vehicle than the wiring harness inside the car body.

[0003] In particular, the bending part of the automobile chassis wiring harness is a key and easily damaged part of the automobile chassis wiring harness. During the operation of the car, the chassis wiring harness not only has to withstand mechanical stress, but also faces complex environmental factors. The bending part of the automobile chassis wiring harness is frequently moved and vibrated during the operation of the car, and may suffer varying degrees of damage. In the outer area of ​​the bending part of the wiring harness, the copper wire will be severely stretched and deformed, while in the inner area, mutual extrusion deformation will form. This repeated stress change will cause the physical structure of the bending part of the wiring harness to gradually weaken, and may eventually cause breakage or short circuit. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a car chassis wiring harness protection box to solve the problem that the bending part of the existing car chassis wiring harness is a key and easily damaged part of the car chassis wiring harness. During the operation of the car, the chassis wiring harness not only has to withstand mechanical stress, but also faces complex environmental factors. The bending part of the car chassis wiring harness is frequently moved and vibrated during the operation of the car, and may suffer varying degrees of damage.

[0005] The technical solution adopted by the utility model is as follows: an automobile chassis wiring harness protection box, comprising a box body, wherein the box body comprises a long side portion, a bending portion and an arc portion connected in sequence;

[0006] Side panels are provided on both sides of the box body, and the two side panels and the box body are combined to form a wiring channel. Side panels are adaptively provided along the long side, the bending part and the arc part of the box body;

[0007] A plurality of binding pieces are arranged on the box body.

[0008] Furthermore, two first reinforcing ribs are arranged on the outer side wall of the side plate on one side, and the two first reinforcing ribs are located on the outer side wall of the side plate opposite to the bending portion.

[0009] Furthermore, one end of the two first reinforcing ribs away from the bending portion is fixedly connected with a second reinforcing rib, and the second reinforcing rib is located on the side of the side plate away from the bending portion, and the second reinforcing rib is arranged in a bent shape.

[0010] Furthermore, it also includes a reinforcing rib plate, which is fixedly penetrated on the side plate on the other side, and the reinforcing rib plate is located at the side plate relative to the bending portion.

[0011] Furthermore, a waist-shaped hole is provided on the reinforcing rib plate.

[0012] Furthermore, it also includes a mounting piece, which is provided with a mounting hole, and two opposite arc-shaped spring blocks are symmetrically arranged on the inner side wall of the mounting hole.

[0013] Furthermore, the binding piece includes two binding holes symmetrically arranged on both sides of the box body.

[0014] Beneficial effects of the utility model:

[0015] 1. Place the chassis wiring harness of the car into the box along the long side of the box, insert the bent part of the wiring harness into the bent part of the box, and insert the other side of the wiring harness into the arc-shaped part. Then use a cable tie to pass through the bundling hole to bundle the wiring harness inside the box and the side panels. Since the bent part of the wiring harness is inserted into the bent part of the box, and the side panels on both sides are used to wrap the bent part of the wiring harness, it plays a protective role and avoids being squeezed and deformed.

[0016] 2. The first reinforcing rib is provided to help strengthen the structural strength of the side of the bending portion, so that the automobile chassis wiring harness at the bending portion is not easily deformed by external extrusion and interference, thereby improving the mechanical strength of the wire protection box.

[0017] 3. By fixing the second reinforcing rib at one end of the two first reinforcing ribs away from the bending portion, the two first reinforcing ribs are cross-connected with the second reinforcing ribs, and a stable structure is formed at the intersection of the cross-connected first reinforcing ribs and the second reinforcing ribs, which can effectively disperse and transmit impact forces from different directions and protect the wiring harness from damage.

[0018] 4. By inserting a reinforcing rib plate on the side panel opposite to the bending portion, the structural strength of the side panel relative to the bending portion is enhanced to prevent the wiring harness from being damaged by external force such as squeezing, stretching or twisting during driving.
