With the continuous increase of the demands of consumers on the safety, comfort and entertainment of automobiles, the types and the number of vehicle-mounted electric appliances are continuously increased in recent years, which directly leads to the continuous increase of the volume and the quality of automobile wire harnesses. The rear seat entertainment technology, the vehicle-mounted refrigerator technology and the like make a rear power supply of the trunk indispensable, and the positive and negative lines of the rear power supply are thick, so that a large space is occupied. Meanwhile, the wire harness is often subjected to large pressure and is easy to damage. In addition, the wire harness is easy to wear by sharp edges of the metal plates, and the service life is further shortened. The high-voltage wire harness protection box is arranged to protect the high-voltage wire, so that the service life of the high-voltage wire is prolonged.

As mentioned in the background art, the existing high-voltage wire harness protection box cannot meet the protection requirement of the high-voltage wire of the hybrid electric vehicle. On the one hand, the existing high-voltage wire harness protection box uses more materials and has higher cost because the upper cover and the lower cover are used simultaneously. On the other hand, the mounting point occupies a space such that it cannot be arranged in a narrow arrangement space reserved for the high-voltage wire.

To the problem among the prior art, this application provides a high-voltage harness wire protecting box.

The mounting bracket 11a is sheet-like, i.e. the mounting bracket 11a can be considered approximately to lie in one plane. The included angle between the plane of the mounting bracket 11a and the plane of the side wall 121 is the included angle between the extending direction of the mounting bracket and the side wall of the cable accommodating groove. In fig. 1, the plane of the mounting bracket 11a and the plane of the side wall 121 are in the same plane, i.e. the extending direction of the mounting bracket and the side wall of the cable receiving groove form an angle of 0 °.

With continued reference to fig. 1, the mounting bracket 11b is sheet-like, i.e., the mounting bracket 11b can be considered approximately to lie in one plane. The mounting bracket 11b is fixedly connected with the side wall 122 of the cable accommodation groove 12. The included angle between the plane of the mounting bracket 11b and the plane of the side wall 122 is the included angle α between the extending direction of the mounting bracket and the side wall of the cable containing groove.

Optionally, the material of the wire protection box body 10 and the mounting bracket 11 is plastic. In the technical scheme, the wire protecting box body can be formed by pouring through double pouring gates, and the pouring gates are arranged at two opposite ends of the wire protecting box body. Illustratively, referring to fig. 4, gates are located at 21 and 22 of the grommet body. Optionally, the gate is placed at 1/4 and 3/4 of the total length along the extending direction of the high-voltage wire harness, so that smooth injection molding process is ensured, defects such as weld marks are avoided, and meanwhile, the gate is arranged on the back of the wire protection box, so that the whole appearance of the wire protection box is ensured.

Optionally, when the high-voltage harness protection box includes two or more mounting brackets, the two or more mounting brackets are fixed on the same side of the high-voltage harness protection box, so as to save the mounting space of the high-voltage harness protection box.

According to the high-voltage wire harness wire protection box provided by the technical scheme, the wire protection box body is internally provided with the wire containing groove without the cover, so that the wire protection box is used for containing the high-voltage wire harness; the mounting bracket is fixedly connected with the side wall of the cable accommodating groove and is in a sheet shape, and the included angle alpha between the extending direction of the mounting bracket and the side wall of the cable accommodating groove meets the condition that alpha is more than or equal to 0 degree and less than 90 degrees; the wire protection box body and the mounting bracket are integrally formed. Because the wire protection box body is uncovered, the material used for the wire protection box can be fully reduced, and the manufacturing cost of the wire protection box is reduced. In addition, the included angle alpha between the mounting bracket and the side wall of the cable accommodating groove is more than or equal to 0 degrees and less than 90 degrees, so that the occupied space for mounting can be reduced sufficiently.

Further, with continued reference to fig. 2 and 3, the mounting bracket is provided with mounting holes 111; a stainless steel nest 112 is arranged in the mounting hole 111; stainless steel nest 112 presents a stepped shape with a flange; stainless steel nest 112 is used to mate with bolts to secure the high voltage harness cord box to the vehicle.

When the mounting bracket is secured to the vehicle using a bolt, the bolt applies a force to the mounting bracket. If no stainless steel nest is provided, under the action of the force, the mounting bracket and even the whole high-voltage wire harness protection box can be broken. By providing a stainless steel nest in the mounting hole, the bolt will apply a force to the stainless steel nest. Because the hardness of the stainless steel nest is very high, the function of protecting the mounting bracket can be achieved.

The stainless steel nest 112 is provided with a step shape with a flanging, so that the contact position of the stainless steel nest 112 and the mounting bracket forms a step, and the relative movement of the stainless steel nest 112 and the mounting hole 111 is limited, and the stainless steel nest 112 is prevented from falling off from the mounting hole 111.

In one embodiment, optionally, at least one group of first fixing holes is arranged on the bottom surface and/or the side wall of the cable containing groove, one group of first fixing holes comprises two first fixing holes, and the connecting line of the two first fixing holes belonging to the same group is perpendicular to the extending direction of the cable containing groove; the first fixing hole is used for penetrating through the binding belt to fix the high-voltage wire harness in the cable containing groove.

Each set of first fixing holes 13 includes two first fixing holes, namely a first fixing hole 131 and a first fixing hole 132. When the high voltage wire harness needs to be fixed, the binding tape is used to pass through the first fixing hole 131 and the first fixing hole 132 so that the high voltage wire harness is attached to the bottom surface of the cable accommodation groove and fixed in the cable accommodation groove. In this way, it is ensured that the high-voltage wire harness is always in the cable accommodation groove even if the vehicle is slightly rocked during the running process of the vehicle.

On the basis of the technical schemes, optionally, the wire protection box body is also provided with a reinforcing rib; the reinforcing rib is positioned at least one of the following positions: the back of the wire protection box body, the outer side wall of the cable containing groove and the surface of the mounting bracket.
