Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a rubber door component for a new energy vehicle. Background Art

[0002] In order to avoid wear of the car door wiring harness and ensure driving safety, the car door wiring harness generally needs to be fixed in the sheet metal mounting hole on the car through the door wiring harness sheath. The existing door wiring harness sheath mounting structure is to extend an elastic sheath tube at one end to form an elastic guide sleeve. The door wiring harness is inserted through the elastic sheath tube and the middle hole of the elastic guide sleeve, and then passes through the sheet metal mounting hole together with the sheath.

[0003] The utility model with application number "2021219119605" is a high-strength special-shaped protective cover connected to a car door and a car body, which discloses that "the car door connecting end 3 includes a third annular plate 31 connected to the telescopic bellows 1, and a fourth annular plate 32 connected to the third annular plate 31, and a second annular groove 33 is formed at the connection between the third annular plate 31 and the fourth annular plate 32". In the above technical scheme, in order to facilitate installation in actual processing, the width of the second annular groove is usually processed to be greater than the thickness of the car door mounting hole, and only the front end protrusions of the third annular plate and the fourth annular plate can resist the mounting hole to achieve the effect of fixing the protective cover, that is, sealing. The protrusions of the third annular plate and the fourth annular plate are thin, and the extrusion force is small, making it difficult to position the protective cover on the mounting hole, resulting in a reduction in the sealing effect of the protective cover shaking.

Both ends of the telescopic bellows 1 are respectively connected with mounting seats 2, wherein the outer diameter of one mounting seat 2 is smaller than the inner diameter of the door hole, and the other mounting seat 2 is inserted in the door hole. The mounting seat 2 includes an outer side surface integrally formed with a sealing ring 1 3 and a sealing ring 2 4, and a raised lip 5 is provided on one side of the sealing ring 1 3 and the sealing ring 2 4 facing the sealing groove 6. A sealing groove 6 is provided between the sealing ring 1 3 and the sealing ring 2 4, and the width of the sealing groove 6 is smaller than the depth of the door hole. The door hole is inserted in the sealing groove 6, and the sealing ring 1 3 and the sealing ring 2 4 are respectively in contact with the inner and outer sides of the door hole, and the outer side surface of the sealing ring 2 4 is set as an inclined extrusion surface. The inner wall of the mounting seat 2 is provided with a stretching groove, and a stretching assembly is fixed in the stretching groove. The stretching assembly includes a stretching ring 7 arranged at both ends and a plurality of elastic support sheets 8 distributed circumferentially between the two stretching rings 7, a gap is arranged between two adjacent elastic support sheets 8, the inner wall of the mounting seat 2 corresponding to the position of the sealing ring 2 4 abuts against the elastic support sheet 8, the inner sides of the sealing ring 1 3 and the sealing ring 2 4 are provided with support grooves, the extension depth of the support grooves is greater than two-thirds of the depth of the sealing ring 1 3 and the sealing ring 2 4, the outer diameter of the stretching ring 7 inserted in the sealing ring 1 3 is greater than the outer diameter of the stretching ring 7 inserted in the sealing ring 2 4, the two stretching rings 7 are respectively inserted in a concave-convex manner and extend into the sealing ring 1 3 and the sealing ring 2 4, the elastic support sheet 8 is arranged as an arc-shaped sheet convex outward in the middle, and the inner wall of the mounting seat 2 corresponding to the position of the sealing ring 2 4 of the sealing ring 2 4 abuts against the middle of the arc-shaped convexity of the elastic support sheet 8.

[0026] Working principle:
