DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A sealing sheath for automobile chassis wiring harness comprises a base 1 and a guide column 2, wherein the base 1 comprises a bottom plate 5, a baffle 4 and a sealing convex edge 7, wherein the baffle 4 is arranged around the periphery of the surface of the bottom plate 5, and the sealing convex edge 7 is arranged around the upper surface of the baffle 4 and folded outward, so that a receiving groove 43 is formed between the baffle 4 and the bottom plate 5, and a mounting groove 71 is formed between the sealing convex edge 7 and the outer surface of the baffle 4. The guide column 2 is located at the center of the bottom plate 5 and extends downward from the bottom plate 5 vertically, so that the guide column 2 is located on the bottom plate 5 and is perpendicular to the surface of the bottom plate 5, and a through hole 21 is formed along the length direction of the guide column 2. A fixing ring 3 is arranged at the center of the receiving groove 43, the fixing ring 3 surrounds the through hole 21, the upper surface of the fixing ring 3 is open, and a through groove 32 that intersects with the through hole 21 is formed in the fixing ring 3, and the wiring harness passes through the through hole 21 and the through groove 32. When the wire harness passes through the through hole 21 and the through groove 32 , in order to prevent the wire harness from moving back and forth in the through hole 21 and the through groove 32 , a plurality of convex rings 22 are provided below the inner wall of the through hole 21 . The convex rings 22 are provided to increase the friction between the wire harness and the inner wall of the through hole 21 .

[0029] Reference Figure 1 and Figure 4 , grooves 31 are formed on both sides of the fixing ring 3, and the bottom surface of the groove 31 is set to be an inclined surface. When the wiring harness sealing sheath is assembled with the automobile chassis, the accessories assembled with the wiring harness sealing sheath include a cylindrical accessory 8 and a rectangular parallelepiped accessory 9, and one end of the rectangular parallelepiped accessory 9 is connected to the cylindrical accessory 8. The cylindrical accessory 8 located at the automobile chassis is embedded in the through groove 32 of the fixing ring 3 of the wiring harness sealing sheath, and the buckle on the outer surface of the cylindrical accessory 8 is embedded in the groove 31 on the surface of the fixing ring 3. The buckle is embedded in the groove 31 to install and fix it. Not only does it make the cylindrical accessory 8 and the wiring harness sealing sheath firmly installed and fixed, but it also has the advantage of easy disassembly. The wiring harness sealing sheath is made of chloroprene rubber material, and the base 1 and the guide column 2 are integrally formed, so that the wiring harness sealing sheath has good heat resistance, flame resistance and acid and alkali resistance. The wiring harness sealing sheath made of chloroprene rubber material has high tensile strength, elongation and reversible crystallinity, and can be used for a long time at 80-100°C.

[0030] The wire harness passes through the through hole 21 of the guide column 2 into the cylindrical accessory 8, and then passes through the rectangular accessory 9. In order to accurately control the direction of the wire harness, a pair of positioning grooves 41 are formed on the surface of the enclosure 4. The shape of the fixing ring 3 set in the accommodating groove 43 is cylindrical, and the two positioning grooves 41 are symmetrical about the center of the fixing ring 3, and the edges of the positioning grooves 41 are located at the tangent position of the edge of the fixing ring 3. The width dimension of the positioning groove 41 is set to be equal to the width dimension of the rectangular accessory 9. After the cylindrical accessory 8 and the fixing ring 3 are installed and fixed, the rectangular accessory 9 is embedded in one of the positioning grooves 41 on the surface of the enclosure 4, thereby fixing the direction of the wire harness.

[0031] Reference Figure 5 In order to make the overall structure of the harness sealing sheath stable, a plurality of inner ribs 6 are formed in the receiving groove 43. The inner ribs 6 are located between the fixing ring 3 and the enclosure 4. The inner ribs 6 are respectively connected and fixed to the bottom plate 5, the fixing ring 3 and the enclosure 4. The inner ribs 6 can be divided into a first rib 61 and a second rib 62. The height of the first rib 61 is greater than the height of the second rib 62. Four first ribs 61 and eight second ribs 62 are arranged in the receiving groove 43. The four first ribs 61 are distributed in a "cross" shape in the receiving groove 43. Two second ribs 62 are arranged between two adjacent first ribs 61, so that the plurality of inner ribs 6 are symmetrical about the center of the fixing ring 3.

[0032] Reference Figure 6 and Figure 7The harness sealing sheath is installed in the mounting hole of the automobile chassis. To facilitate the installation of the harness sealing sheath and the automobile chassis, a side of the enclosure 4 close to the bottom plate 5 is provided to form a guide slope 42, and the provided guide slope 42 is inclined inward from top to bottom. When installing the harness sealing sheath and the automobile chassis, the guide column 2 is passed through the mounting hole of the automobile chassis, so that the side of the guide slope 42 close to the base 1 is first embedded in the mounting hole of the automobile chassis, and then the guide column 2 is pulled so that the guide slope 42 and the inner wall of the mounting hole are more firmly embedded.

[0033] After the harness sealing sheath is assembled with the automobile chassis, in order to achieve a good sealing effect between the harness sealing sheath and the automobile chassis, the lower surface of the sealing convex edge 7 is tilted inward, and a flange 44 for contacting the mounting surface is provided at the mounting groove 71 of the enclosure 4. After the guide inclined surface 42 of the harness sealing sheath is embedded with the mounting hole of the automobile chassis, the sealing convex edge 7 of the enclosure 4 is abutted against the upper surface of the mounting surface of the automobile chassis, and the flange 44 provided on the enclosure 4 is abutted against the lower surface of the mounting surface of the automobile chassis. In this way, the gap between the harness sealing sheath and the automobile chassis is blocked. By using the harness sealing sheath, the harness can be reasonably arranged and fixed under the condition of specific laying space in the car. This harness sealing sheath can not only ensure the fixation of the harness outside the car and inside the car, but also effectively prevent water stains and dust from entering the car from the outside of the chassis. More importantly, it can play a role in heat insulation and flame retardancy, effectively ensuring the comfort and safety of people in the cab.

[0034] The specific implementation principle of the embodiment of the present application is: when using the wire harness sealing sheath, the cylindrical accessory 8 is embedded in the fixing ring 3 of the wire harness sealing sheath during installation, and the buckle on the circumferential surface of the cylindrical accessory 8 is embedded in the card groove 31 of the fixing ring 3, and the rectangular accessory 9 connected to the cylindrical accessory 8 is embedded in the positioning groove 41 on the surface of the enclosure 4; the wire harness can pass through the rectangular accessory 9 into the cylindrical accessory 8, and finally pass through the through hole 21 of the guide column 2.

[0035] Then, the guide column 2 is inserted into the mounting hole of the automobile chassis, so that the guide slope 42 of the wire harness sealing sheath abuts against the inner wall of the mounting hole. According to different use environments, the wire harness sealing sheath can be installed with the automobile chassis by pressing down (push installation) or pulling down (pull installation). Finally, the sealing convex edge 7 on the outer peripheral side of the enclosure 4 abuts against the upper surface of the automobile chassis mounting surface, and the flange 44 set on the enclosure 4 abuts against the lower surface of the automobile chassis mounting surface, thereby having a good sealing effect between the wire harness sealing sheath and the automobile chassis. The wire harness sealing sheath can be installed with the automobile chassis by pressing down (push installation) or pulling down (pull installation), making it easier to assemble and operate.

[0036] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
