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 1-8 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 3A car firewall sealing cover comprises a base 1 and a mounting member 2, wherein the base 1 comprises a bottom plate 11, a guide column 12, a fixing ring 13 and a baffle 14, wherein the guide column 12 is vertically arranged at the center of the surface of the bottom plate 11, the fixing ring 13 is located on the bottom plate 11 and is arranged concentrically with the guide column 12, so that a fixing groove 16 is formed between the fixing ring 13 and the guide column 12; the baffle 14 is arranged on the peripheral side of the surface of the bottom plate 11, so that a mounting groove 17 is formed between the baffle 14 and the fixing ring 13. A main hole 121 for the wire harness to pass through is formed along the length direction of the guide column 12, and in order to make the sealing cover adapt to the installation of different vehicle configurations, a wire column 15 is vertically arranged on one side of the guide column 12, and a secondary hole 151 is formed along the length direction of the wire column 15, and a sealing sheet 152 is formed at one end of the wire column 15, thereby forming a double-hole straight-through wire harness guide structure. When the auxiliary hole 151 of the use wire column 15 is not provided, the auxiliary hole 151 is blocked by the sealing sheet 152 to prevent noise, dust and exhaust gas from entering the cab through the auxiliary hole 151.

[0029] In addition, extension platforms 18 are formed on both sides of the enclosure 14. When the product is produced, the extension platforms 18 on both sides of the enclosure 14 can be pulled to facilitate mold opening and product removal. The mounting member 2 is made of PA66 material, and the base 1 is made of EPDM rubber material. The mounting member 2 made of PA66 material has good impact resistance, and the base 1 made of EPDM rubber material has good heat resistance, high pressure resistance and aging resistance. The mounting member 2 is arranged in a ring shape, and the mounting member 2 is detachably installed in the mounting groove 17, so that the sealing sleeve adopts a separate split assembly structure, which reduces the difficulty of production and reduces the product installation force, making it easier to feel that the product is fully assembled into the body sheet metal.

[0030] Reference Figure 4 , Figure 5 and Figure 6 , a limiting platform 19 is formed along the inner circumference of the enclosure 14, so that a limiting groove 191 is formed between the limiting platform 19 and the bottom plate 11, and a mounting platform 21 is formed on the circumference of the end of the mounting member 2 correspondingly, and the thickness of the mounting platform 21 is equal to the height of the limiting groove 191. When the mounting member 2 is installed in the mounting groove 17, the mounting platform 21 on the circumference of the mounting member 2 is embedded in the limiting groove 191, so that the mounting member 2 and the base 1 are firmly installed. After the mounting member 2 and the base 1 are installed, in order to prevent the mounting member 2 and the base 1 from rotating relative to each other, a plurality of positioning blocks 131 are formed on the outer circumference of the fixing ring 13, and a plurality of positioning grooves 23 are formed on the inner circumference of the mounting member 2 correspondingly, and after the mounting member 2 is embedded in the mounting groove 17, each positioning block 131 is embedded in each positioning groove 23.

[0031] Reference Figure 3 , Figure 7 and Figure 8 After the mounting member 2 is mounted in the mounting groove 17 of the base 1, the sealing sleeve is mounted in the sheet metal hole of the vehicle body, the main wire harness is passed through the main hole 121 of the guide column 12, and the sealing sheet 152 on the surface of the wire column 15 is removed, and the small wire harness is passed through the secondary hole 151 of the wire column 15. In order to ensure that the sealing sleeve is firmly installed in the sheet metal hole, a plurality of buckles 22 are formed on the outer peripheral side of the mounting member 2, and a clamping rib 192 is obliquely arranged on the limit platform 19, the oblique direction of the clamping rib 192 points to the buckle 22, and the side of the clamping rib 192 away from the limit platform 19 is in the same vertical plane as the buckle 22, and a gap is maintained between each buckle 22 and the clamping rib 192. After the sealing sleeve is mounted in the sheet metal hole of the sheet metal member 3, the inner side wall of the sheet metal hole is embedded between each buckle 22 and the clamping rib 192, so that the sealing sleeve is firmly installed in the sheet metal hole. In addition, an installation mark 111 is arranged on the surface of the bottom plate 11 , and the installation mark 111 can indicate the position of the extension platform 18 . The arrangement of the installation mark 111 facilitates the installation of the sealing sheath.

[0032] In order to ensure that the sealing sleeve is firmly installed in the sheet metal hole of the vehicle body, the extension platforms 18 on both sides of the enclosure 14 can be firmly tied to the sheet metal part 3 of the vehicle body with cable ties to prevent the base 1 from being separated from the mounting part 2 due to too many and too heavy wire harnesses. In order to ensure that the sealing sleeve has a good sealing effect after being installed with the sheet metal part 3, a sealing rib 141 is obliquely arranged on the surface of the enclosure 14, and the oblique direction of the sealing rib 141 is opposite to the oblique direction of the clamping rib 192. After the sealing sleeve is installed in the sheet metal hole of the sheet metal part 3, the sealing rib 141 arranged on the surface of the enclosure 14 abuts against the surface of the sheet metal part 3, thereby forming an important barrier to isolate noise, dust, heat sources and exhaust gas.

[0033] The specific implementation principle of the embodiment of the present application is as follows: when the sealing sheath is needed, the mounting member 2 is installed in the mounting groove 17 of the base 1. Since the base 1 is made of EPDM rubber material, a certain deformation may occur; after installation, the positioning block 131 on the outer peripheral side of the fixing ring 13 is embedded in the positioning groove 23 on the inner peripheral side of the mounting member 2, and the mounting platform 21 on the outer periphery of the end of the mounting member 2 is embedded in the limiting groove 191, so that the mounting member 2 and the base 1 are firmly installed. The main wiring harness in the engine compartment is passed through the main hole 121 of the guide column 12. The sealing sheet 152 at the end of the wire column 15 can be broken as needed, so that the small wiring harness is passed through the secondary hole 151 of the wire column 15.

[0034] The guide column 12 of the base 1 can be inserted into the sheet metal hole of the body sheet metal 3, and the fixing part in the body cab is inserted into the fixing groove 16 between the fixing ring 13 and the guide column 12, and the inner wall of the sheet metal hole is inserted between the clamping rib 192 and the buckle 22, so that the sealing sleeve is firmly installed in the body sheet metal hole. In addition, the extension platform 18 on both sides of the enclosure 14 can be firmly tied to the sheet metal 3 of the body by a cable tie to prevent the base 1 from being separated from the mounting part 2 due to too many heavy wire harnesses. After the sealing sleeve is installed in the sheet metal hole of the body sheet metal 3, the sealing rib 141 set on the enclosure 14 abuts against the surface of the sheet metal 3, thereby achieving a sealing effect between the sealing sleeve and the sheet metal 3, so as to prevent noise, dust and exhaust gas from entering the cab through the gap between the sealing sleeve and the sheet metal 3, and to maximize the comfort and safety of the driver and passengers.

[0035] 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.
