Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a headlight wire anti-backflow mechanism. Background Technology

[0002] In the automotive manufacturing industry, the connection stability of headlight wiring harnesses is crucial for the normal operation of headlights. With existing headlight wiring harness connection methods, during vehicle operation, external factors such as bumps and vibrations can easily cause the wiring harnesses to loosen or even detach. This not only prevents the headlights from illuminating properly, affecting driving safety, but may also trigger electrical faults, adversely impacting the overall performance and reliability of the vehicle.

[0003] Currently, although there are some wiring harness fixing devices for fixing vehicle headlight wiring harnesses, most of them have complex structures, are inconvenient to install, and are not ideal in preventing the wiring harnesses from being pulled off, thus failing to effectively solve the problem of vehicle headlight wiring harnesses easily falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle light wiring harness anti-detachment mechanism to solve the problem of existing vehicle light wiring harnesses being prone to detachment.

[0005] To achieve the above objectives, this utility model provides a vehicle light wire anti-reverse mechanism, which includes a rubber seat, a fixing mechanism, and a wire harness thrust ring. The rubber seat is mounted on the vehicle light housing and is disposed outside the wire harness connection sheet metal hole of the vehicle light housing. The wire harness thrust ring is mounted on the rubber seat at the end away from the vehicle light housing through the fixing mechanism. The vehicle light wire harness is welded inside the wire harness thrust ring using ultrasonic and high-frequency welding techniques. The fixing mechanism includes two insertion posts, two elastic elements, and two fixing posts. The insertion posts are fixedly installed on both sides of the side of the wire harness thrust ring closest to the rubber seat. Fixing holes are provided on both sides of the side of the rubber seat away from the headlight housing. The insertion posts are adapted to the fixing holes. Mounting protrusions are provided on both sides of the rubber seat. The fixing posts are installed inside each mounting protrusion through the elastic elements. Each insertion post is provided with a insertion hole on the side closest to the corresponding mounting protrusion. The fixing posts are adapted to the insertion holes.

[0006] Each of the elastic elements includes a fixed spring, a first connecting ring, and a second connecting ring. One end of the fixed spring is provided with the first connecting ring, and the other end of the fixed spring is provided with the second connecting ring. The first connecting ring is connected to the inner wall of the mounting protrusion, and the second connecting ring is connected to the fixed post.

[0007] Each of the fixing posts has a first inclined surface on the side near the corresponding fixing hole, and each of the insertion posts has a second inclined surface at the bottom, the second inclined surface being adapted to the first inclined surface.

[0008] The thrust ring of the wiring harness has a welding protrusion on the side away from the rubber seat, and part of the vehicle lamp wiring harness is welded inside the welding protrusion.

[0009] The outer shell of the vehicle light wiring harness and the thrust ring of the wiring harness are both made of PVC material.

[0010] This utility model discloses a vehicle light wiring harness anti-detachment mechanism, comprising a rubber seat, a fixing mechanism, and a wiring harness thrust ring. The fixing mechanism includes two insertion posts, two elastic elements, and two fixing posts. The rubber seat has mounting protrusions on both sides, and each mounting protrusion houses a fixing post via an elastic element. The vehicle light wiring harness is welded to the inside of the wiring harness thrust ring using ultrasonic and high-frequency welding techniques, thus fixing the wiring harness thrust ring to the rubber seat. The insertion posts are then inserted into the fixing holes. During insertion, the fixing posts exert force on the elastic elements, compressing the elastic elements. When the insertion post is fully inserted into the fixing hole, the fixing posts, under the restoring force of the elastic elements, are inserted into the insertion hole, thereby completing the installation of the wiring harness thrust ring. This structure significantly enhances the stability of the wiring harness installation and effectively prevents the vehicle light wiring harness from detaching. Attached Figure Description

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] Please see Figure 1 and Figure 2 This utility model provides a vehicle light wire anti-reverse mechanism, which includes a rubber seat 101, a fixing mechanism, and a wire harness thrust ring 102. The rubber seat 101 is installed on the vehicle light housing 103 and is located outside the wire harness connection sheet metal hole 104 of the vehicle light housing 103. The wire harness thrust ring 102 is installed on the rubber seat 101 away from the vehicle light housing 103 through the fixing mechanism. The vehicle light wire harness 105 is welded inside the wire harness thrust ring 102 by ultrasonic and high-frequency welding technology. The fixing mechanism includes two insertion posts 106, two elastic elements, and two fixing posts 107. The insertion posts 106 are fixedly provided on both sides of the side of the wire harness thrust ring 102 near the rubber seat 101. Fixing holes 108 are provided on both sides of the side of the rubber seat 101 away from the headlight housing 103. The insertion posts 106 are adapted to the fixing holes 108. Mounting protrusions 109 are provided on both sides of the rubber seat 101. The fixing posts 107 are installed inside each mounting protrusion 109 through the elastic elements. Each insertion post 106 is provided with a socket 110 on the side near the corresponding mounting protrusion 109. The fixing posts 107 are adapted to the socket 110.

[0017] In this embodiment, ultrasonic and high-frequency welding techniques are used to weld the vehicle light wiring harness 105 inside the wiring harness thrust ring 102, and the wiring harness thrust ring 102 is fixed on the rubber seat 101, so that the insertion post 106 is inserted into the fixing hole 108. During the insertion process, the insertion post 106 applies force to the elastic member through the fixing post 107. At this time, the elastic member is in a compressed state. When the insertion post 106 is completely inserted into the fixing hole 108, the fixing post 107 is inserted into the insertion hole 110 under the restoring force of the elastic member, thereby completing the installation of the wiring harness thrust ring 102. With the above structure, the stability of the wiring harness installation is greatly enhanced, and the vehicle light wiring harness 105 is effectively prevented from falling off.

[0018] Furthermore, each of the elastic elements includes a fixed spring 111, a first connecting ring 112, and a second connecting ring 113. One end of the fixed spring 111 is provided with the first connecting ring 112, and the other end of the fixed spring 111 is provided with the second connecting ring 113. The first connecting ring 112 is connected to the inner wall of the mounting protrusion 109, and the second connecting ring 113 is connected to the fixed post 107.

[0019] In this embodiment, the installation of the elastic element is completed by setting the first connecting ring 112 and the second connecting ring 113.

[0020] Furthermore, each of the fixing posts 107 has a first inclined surface 114 on the side near the corresponding fixing hole 108, and each of the insertion posts 106 has a second inclined surface 115 at the bottom, the second inclined surface 115 being adapted to the first inclined surface 114.

[0021] In this embodiment, by setting the first inclined surface 114 and the second inclined surface 115, when the insertion post 106 is inserted into the interior of the fixing hole 108, it can better apply force to the fixing post 107, so that the fixing post 107 can slide inside the mounting protrusion 109.

[0022] Furthermore, the side of the wire harness thrust ring 102 away from the rubber seat 101 is provided with a welding protrusion 116, and part of the vehicle lamp wire harness 105 is welded inside the welding protrusion 116.

[0023] In this embodiment, the welding protrusion 116 increases the contact area and welding area between the headlight wiring harness 105 and the wiring harness thrust ring 102, making the ultrasonic and high-frequency welding more robust and improving the connection strength between the headlight wiring harness 105 and the wiring harness thrust ring 102. This effectively prevents the headlight wiring harness 105 from coming out of the wiring harness thrust ring 102 when under stress. At the same time, the welding protrusion 116 can disperse the tensile force on the headlight wiring harness 105 to a certain extent, so that the tensile force is applied more evenly to the welding part between the headlight wiring harness 105 and the wiring harness thrust ring 102, reducing local stress concentration and extending the service life of the headlight wiring harness 105 and the welding part.

[0024] Furthermore, both the outer shell of the vehicle light wiring harness 105 and the wiring harness thrust ring 102 are made of PVC material.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
