Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, specifically relating to a sealing structure for automotive combination headlight wiring harness and vehicle lamp. Background Technology

[0002] With the rapid development of modern automotive technology, the design of automotive lights also needs to be improved as the performance of automobiles continues to improve. Currently, all kinds of automotive lights are integrated and connected through automotive wiring harnesses. The automotive wiring harness is equivalent to the nerves of the electrical network inside the car, used to control the normal use of automotive lights.

[0003] A common automotive combination headlight includes front turn signals, fog lights, daytime running lights, and high / low beam headlights. These headlights are powered and controlled via an automotive lighting wiring harness assembly. Existing automotive lighting wiring harnesses consist of a main connector, multiple wiring harness plugs, and several wire harnesses. The multiple wiring harness plugs are connected to the main connector via individual wire harnesses. The main connector mates with the connectors on the automotive lights to establish circuitry for the front turn signals, fog lights, daytime running lights, and high / low beam headlights. To ensure a tight seal between the main connector and the multiple wiring harness plugs, a rubber sealing sleeve is typically installed between the main connector and the plugs to allow the wire harnesses to pass through. (See reference...) Figure 8 Several wire harnesses 01 are inserted into the through holes of rubber sealing sleeves 02, and then the rubber sealing sleeves 02 are installed on the mounting holes at the preset positions on the vehicle. This seals and isolates the main connector 03 from the multiple wire harness plugs, protecting the wire harnesses and achieving a sealed connection, effectively isolating them from external moisture and dust. However, in actual use, the following problem still exists: when assembling the wire harnesses, accidental contact or slight pressure is applied to the rubber sealing sleeves, which can easily cause them to loosen and fall off.

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] The technical solution of this utility model will be described in detail below with specific embodiments.

[0033] refer to Figure 1-7 As shown, the present invention provides a sealing structure for a car headlight harness, including an elastic sealing plug 1 and a lamp housing body 2. The elastic sealing plug 1 has a first groove 3 along the circumferential direction, and one end of the elastic sealing plug 1 extends in the axial direction away from the first groove 3 to form a first protrusion 4.

[0034] The lamp housing body 2 is provided with a second protrusion 5, and the first protrusion 4 is arranged in the same direction as the second protrusion 5; the second protrusion 5 is provided with a through groove 6 that cooperates with the elastic sealing plug 1, the through groove 6 includes a groove bottom, the groove bottom is provided with a slot hole for the elastic sealing plug 1 to pass through, and the groove bottom is annular in shape so that the groove bottom is embedded in the first groove 3;

[0035] The elastic sealing plug 1 is provided with a through hole 14 connecting the inner and outer sides of the lamp housing body 2, and the through hole 14 is used for the wire harness to pass through.

[0036] Specifically, in this application, the first protrusion 3, the third protrusion 7, the fourth protrusion 8, and the support member 13 are all integrally formed with the elastic sealing plug 1. The main purpose of setting the first protrusion 4 is to disperse some of the energy generated during vibration to the first protrusion 4. When the assembly wiring harness accidentally touches or applies slight pressure to the elastic sealing plug 1, the first protrusion 4 deforms to provide a gentler resistance feedback, avoiding the complete and direct transmission of impact force to the connection between the elastic sealing plug 1 and the through groove 6. This greatly reduces the risk of loosening caused by frequent minor misoperations. Since the lamp housing body 2 has multiple components and wiring harnesses inside, the first protrusion... 4 is positioned towards the outside of the lamp housing body 2 to prevent the first protrusion 4 from occupying the internal space of the lamp housing body 2, thereby improving the utilization rate of the internal wall space of the lamp housing body 2; the second protrusion 5 is positioned on the outside of the lamp housing body 2 and is integrally formed with the lamp housing body 2. Its main function is to resist large lateral impact forces to prevent the elastic sealing plug 1 from loosening and falling off; preferably, the elastic sealing plug 1 is made of TPV material, and the lamp housing body 2 is made of rigid material. The first protrusion 4 and the second protrusion 5 are arranged in the same direction to form a double protection system of "rigid second protrusion 5 + elastic first protrusion 3", which more effectively reduces the risk of the elastic sealing plug 1 loosening and falling off.

[0037] In this embodiment, as Figure 2-3 and Figure 5-7 As shown, the elastic sealing plug 1 extends along the circumferential direction to form a third protrusion 7 and a fourth protrusion 8, respectively. The first groove 3 is disposed between the third protrusion 7 and the fourth protrusion 8. The third protrusion 7 abuts against one side of the bottom of the through groove 6, and the fourth protrusion 8 abuts against the other side of the bottom of the through groove 6.

[0038] Specifically, the first groove 3 is formed by the distance between the third protrusion 7 and the fourth protrusion 8, wherein the distance between the third protrusion 7 and the fourth protrusion 8 is approximately equal to the thickness of the bottom of the through groove 6, so that the elastic sealing plug 1 is tightly engaged in the through groove 6.

[0039] In this embodiment, as Figure 5-6 As shown, the third protrusion 7 is a solid structure, and the interior of the fourth protrusion 8 is provided with a second groove 9 formed from the outside to the inside in the circumferential direction. The radius of the third protrusion 7 is smaller than the radius of the fourth protrusion 8, and the first protrusion 4 is disposed at the end of the third protrusion 7 away from the second groove 9.

[0040] Specifically, the main purpose of providing the second groove 9 within the fourth protrusion 8 is to allow the fourth protrusion 8 to undergo slight deformation in order to extend the service life of the elastic sealing plug 1. That is, in a vibrating working environment, by providing the second groove 9, the fourth protrusion 8 deforms to disperse the energy generated during vibration, thereby extending the service life of the elastic sealing plug 1. The thickness of the outer wall at the port of the fourth protrusion 8 is greater than the thickness of the main body of the fourth protrusion 8. That is, the port of the fourth protrusion 8 does not undergo significant deformation to maintain a tight contact with the bottom of the through groove 6, while the main body of the fourth protrusion 8 undergoes significant deformation to disperse the energy generated during vibration. The third protrusion 7 is the pressure-bearing part where the elastic sealing plug 1 engages with the through groove 6. It is set to be solid to ensure the connection strength at the connection between the elastic sealing plug 1 and the through groove 6.

[0041] In this embodiment, as Figure 6 As shown, a first cavity 41 is provided at the first protrusion 4, and a plurality of third grooves 10 are uniformly provided at the first protrusion 4 along the circumferential direction.

[0042] Specifically, the third groove 10 in this application is a U-shaped groove. The U-shaped groove creates a locally weak but resilient area at the root of the first protrusion 4. When subjected to force, all bending deformations occur actively and centrally within this U-shaped groove area. That is, by "isolating" the deformation within the U-shaped groove area, unnecessary and uncontrollable deformations of the entire first protrusion 4 or the entire elastic sealing plug 1 are avoided. Furthermore, the U-shaped groove provides a uniform stress distribution. That is, when bending, the arc-shaped inner wall of the U-shaped groove allows the stress to be smoothly distributed along the arc, avoiding excessive stress at a single point.

[0043] In this embodiment, the length of the first protrusion 4 extending in the axial direction is 9-12mm, and the thickness of the sidewall of the first protrusion 4 extending in the circumferential direction is 1.5-2.5mm.

[0044] Preferably, the length of the first protrusion extending in the axial direction is 10.5 mm, and the thickness of the sidewall extending in the circumferential direction of the first protrusion is 1.7 mm.

[0045] In this embodiment, as Figure 6-7 As shown, a first reinforcing rib 11 is provided on the outer side of the first protrusion 4 along the circumferential direction.

[0046] Specifically, the first reinforcing rib 11 is located at the port of the first protrusion 4. Its main function is to distribute the impact force evenly on the first protrusion 4. That is, the first reinforcing rib 11 enhances the local strength at the port of the first protrusion 4. When the assembly wire harness is accidentally touched or slight pressure is applied to the first protrusion 4, no obvious deformation occurs at the port of the first protrusion 4, while the main body of the first protrusion 4 undergoes obvious deformation, thereby distributing the impact force evenly on the first protrusion 4.

[0047] In this embodiment, as Figure 7 As shown, the other end of the elastic sealing plug 1 is provided with a second cavity 12, and a support member 13 is provided in the second cavity 12. The support member 13 extends axially to the bottom surface of the first cavity 41 of the first protrusion 4. The support member 13 is provided with a through hole 14 for inserting wires, and the through hole 14 communicates with the first cavity 41.

[0048] Specifically, the second concave cavity 12 is provided in this application to reduce the weight of the elastic sealing plug 1. The support member 13 is provided to extend the path for external moisture and dust to enter the lamp housing body 2 through the through hole 14, thus playing a protective role.

[0049] In this embodiment, as Figure 7As shown, a plurality of second reinforcing ribs 15 are uniformly arranged in the circumferential direction inside the second cavity 12. One side of the second reinforcing rib 15 abuts against the groove wall of the second cavity 12, and the other side of the second reinforcing rib 15 abuts against the outer wall of the support member 13.

[0050] Specifically, the main purpose of setting the second reinforcing rib 15 is to prevent the support member 13 from shaking or deforming due to the pulling of the wire harness in a vibrating working environment. At the same time, it strengthens the second cavity 12 and reduces the risk of the second cavity 12 sinking.

[0051] In one possible embodiment, the other end of the resilient sealing plug 1 is solid, with a through hole 14 for wire insertion directly there.

[0052] In this embodiment, as Figure 4 As shown, the outer wall of the second protrusion 5 is provided with a third reinforcing rib 16.

[0053] Specifically, the third reinforcing rib 16 is located at the root of the outer wall of the second protrusion 5, and its function is to strengthen the overall strength of the second protrusion 5 and prevent it from breaking when subjected to impact.

[0054] This application also discloses a vehicle lamp, including the automotive combination headlight wiring harness sealing structure disclosed in the above embodiments. Therefore, the vehicle lamp with this sealing structure also has all the above-mentioned technical effects, which will not be elaborated here.

The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
