From this, it can be understood that the wire harness sheath 100 of the present invention is formed by directly bonding the first sheath layer 1 and the second sheath layer 3 during design, that is, the wire harness sheath 100 is formed on the parts. Compared with the existing wire harness sheath 100, the quantity and the complexity of the structure are fewer and simpler in structure, and the shapes of the first sheath layer 1 and the second sheath layer 3 can be adjusted according to actual needs. Cropped form. Thus, the manufacturing cost of the wire harness sheath 100 is reduced, the development period is shortened, and because the structure of the wire harness sheath 100 is simple, the installation space occupied is relatively small, and it can be used for more car models, so that the wire harness sheath 100 The versatility has been greatly improved.

The wire harness sheath 100 according to the embodiment of the present invention is formed by directly bonding two sheath layers through the connecting layer 2, and jointly defines the wire harness penetration hole 5, which has the characteristics of simple structure and convenient assembly. At the same time, the manufacturing cost is also reduced.

In some embodiments, the connection layer 2 is configured as a double-sided adhesive, and the two sides of the double-sided adhesive are attached and bonded to the first sheath layer 1 and the second sheath layer 3 respectively. It can be understood that the first sheath layer 1 and the second sheath layer 3 achieve the effect of adhesion and fixation under the action of the connecting layer 2, as shown in Figure 4, the connecting layer 2 can be made to Adhesion between the first sheath layer 1 and the second sheath layer 3, and the perforation holes 4 on the connection layer 2 must be connected with the perforation holes 4 on the first sheath layer 1 and the second sheath layer 3 Accurate positioning and alignment are achieved, so that the wire harness passing hole 5 is formed to provide an installation point for the wire harness 200 .

In some embodiments, the area of the bonding surface of the first sheath layer 1 and the area of the bonding surface of the second sheath layer 3 are larger than the area of the bonding surface of the connection layer 2 . It can be understood that, as shown in FIG. 5, both the first sheath layer 1 and the second sheath layer 3 cover the connection layer 2, thereby ensuring that the connection layer 2 can be fully bonded to the adjacent sheath layers, increasing the Adhesion area, improve the effect of adhesion. As shown in FIG. 2 , the area of the first sheath layer 1 is slightly larger than that of the connecting layer 2 , and the area of the second sheath layer 3 is slightly larger than that of the first sheath layer 1 . That is to say, the areas of the sheath layers on both sides of the connecting layer 2 are larger than that of the connecting layer 2, so that when the connecting layer 2 is adhered, it can be attached to the sheath layers on both sides to the maximum extent, thereby improving the adhesion effect.

In some embodiments, both the thickness of the first sheath layer 1 and the thickness of the second sheath layer 3 are greater than the thickness of the connection layer 2 . It can be understood that the first sheath layer 1 and the second sheath layer 3 are the main structure of the wire harness sheath 100, and provide fixed installation points for the wire harness 200, and bear the weight of the wire harness 200 and the Structurally, it is necessary to ensure that the wire harness sheath 100 can provide functions such as vibration reduction and anti-seepage.

Will affect the shear strength of the connecting layer 2. That is, when the connecting layer 2 is stressed, its rheological probability will be greater than that of a thinner adhesive layer, thereby affecting the adhesion strength.

In some embodiments, both the first sheath layer 1 and the second sheath layer 3 are made of chemically cross-linked polyethylene foam material. It is understandable that the chemically cross-linked polyethylene foam material is referred to as XPE material for short. It is made of low-density polyethylene resin plus cross-linking agent and foaming agent after continuous foaming at high temperature. It has good tensile strength and is also It has the advantages of no smell, waterproof, light weight and good wear resistance. The wire harness sheath 100 made of this material can have a longer service life, that is, compared with rubber and other materials, the wire harness sheath in the utility model The sheath 100 is more durable and has a longer replacement cycle, and because of its light weight, it can be ensured that the use of multiple wire harness sheaths 100 will not bring a load burden to the vehicle.

In some embodiments, the first sheathing layer 1 , the connection layer 2 and the second sheathing layer 3 are laminated sequentially along the thickness direction. That is to say, as shown in FIG. 4 , the first sheath layer 1 , the connecting layer 2 and the second sheath layer 3 are all adhered in the form of surface-to-surface contact, so that the contact surface for adhesion is larger. That is to say, the method of laminating sequentially along the thickness direction can make the contact range between the connecting layer 2 and the sheath layers on both sides larger, which is more conducive to the tight connection between the first sheath layer 1 and the second sheath layer 3 .

In some embodiments, the first sheathing layer 1 is adapted to be bonded to the vehicle body sheet metal 300 . Wherein, it should be noted that, as shown in FIG. 3 , the end surface area of the first sheath layer 1 is smaller than the end surface area of the second sheath layer 3 . When the vehicle body sheet metal 300 is constructed with a matching opening size, the first sheath layer 1 can be inlaid with the vehicle body sheet metal 300, so that the end surface of the first sheath layer 1 away from the second sheath layer 3 can be aligned with the The body sheet metal 300 is tightly fitted and connected.

And, the thickness of the first sheath layer 1 is smaller than the thickness of the second sheath layer 3 and greater than the thickness of the connecting layer 2 . As shown in Figure 4, the thickness of the first sheath layer 1 is smaller than the thickness of the second sheath layer 3, which can reduce the depth of the hole in the vehicle body sheet metal 300 structure, thereby avoiding when the first sheath layer 1 is bonded. The structural strength is low due to the excessive depth of the opening, which affects the stability of the structure. Wherein, when the harness sheath 100 is installed behind the body sheet metal 300, the second sheath layer 3 is exposed outside the body sheet metal 300, that is, the second sheath layer 3 is designed to have a larger thickness to increase the overall structure of the wire harness sheath 100. stability, and can improve the service life of the wire harness sheath 100, that is, the second sheath layer 3 can still maintain a relatively stable state under conditions such as wear and extrusion, thereby improving the use of the wire harness sheath 100 as a whole cycle.

In some embodiments, the first sheath layer 1 , the second sheath layer 3 and the connecting layer 2 are formed with smooth transition surfaces 6 at corners. It should be noted that, as shown in Figure 1 and Figure 3, the first sheath layer 1, the second sheath layer 3 and the connecting layer 2 are all formed with a smooth transition surface 6 around the end surface, and the smooth transition surface 6 can be Constructed as a curved surface. It can be understood that designing the smooth transition surface 6 can reduce wear of the wire harness sheath 100 and improve safety. And, the rounded corner design can reduce the stress concentration at key positions, and can also effectively prevent the right-angled edge from hurting people during the production stage. Therefore, the rounded corners of the smooth transition surface 6 can be very practical during installation.
