[0002] During the driving of an automobile, warning lights are arranged around the vehicle body to give warnings to other vehicles. According to the installation positions, they can be divided into front combination lamps and rear combination lamps. In the prior art, there are generally two types of rear combination lamps. One uses bulbs for lighting, and the other uses LED lamp beads for lighting. For a vehicle rear combination lamp using LED lighting, the overall assembly is called an LED module for the rear combination lamp.

[0003] When designing an existing LED module for an automobile rear combination lamp, a wire slot is usually arranged at the rear end of the fixing plate for the LED lamp wiring to pass through. Generally, a rubber sleeve is used to fix multiple groups of wires together, and then the rubber sleeve is passed through the wire slot. Since a group of wires is composed of multiple wires with different thicknesses, the rubber sleeve generally cannot fit the inner wall of the wire slot during use. Thus, when water enters the vehicle interior during actual use, the water flow may enter the interior of the LED module through the wire slot, resulting in fogging or water accumulation in the rear lamp of the vehicle, and the overall device has poor sealing performance. Therefore, an LED module for an automobile rear combination lamp is proposed to solve the above problems. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: an automotive rear combination lamp LED module, which includes a fixing shell 1 for supporting the overall device. An LED lamp row 7 for emitting light is installed on the inner wall of the fixing shell 1. A cover plate 2 for closing the front opening of the fixing shell 1 is slidably connected to the left end of the fixing shell 1. The cover plate 2 is made of transparent PC material and has good light transmittance. A protective sleeve 3 for increasing the connection sealing performance between the cover plate 2 and the fixing shell 1 is fixedly connected to the outer wall of the cover plate 2. The protective sleeve 3 is sleeved on the outer wall of the fixing shell 1. By using the protective sleeve 3 to cover the connection between the cover plate 2 and the fixing shell 1, the external waterproof and dustproof effect of the overall device can be increased. A wire passing groove 6 for allowing the circuit to pass through is provided at the right end of the fixing shell 1. A fixing component 4 for fixing the circuit is provided at the right end of the fixing shell 1. The fixing component 4 includes a baffle 41 for guiding the circuit. The left end of the baffle 41 is fixedly connected to the right end of the fixing shell 1. A protective component 5 for driving the cover plate 2 to move and reset is provided on the inner wall of the protective sleeve 3.

[0032] Refer to Figure 1 - Figure 3 , the fixing component 4 further includes a bottom plate 42 for supporting the lower gasket 45. The top end of the bottom plate 42 is fixedly connected to the bottom end of the baffle 41. A pressing plate 43 for driving the upper gasket 44 to move is installed on the top end of the bottom plate 42. The pressing plate 43 and the bottom plate 42 are fixed to each other by bolts. The bottom end of the pressing plate 43 is fixedly connected with an upper gasket 44 for fixing the circuit. The top end of the bottom plate 42 is fixedly connected with a lower gasket 45 for cooperating with the upper gasket 44 to fix the circuit. The upper gasket 44 and the lower gasket 45 are adapted to each other. Both the upper gasket 44 and the lower gasket 45 are made of rubber material and have good elastic deformation ability. By using the upper gasket 44 to press the lower gasket 45, the circuit can be sealed and fixed at the middle position between the two. Multiple groups of upper gaskets 44 and lower gaskets 45 are provided. The top end of another group of upper gaskets 44 is fixedly connected to the bottom end of the pressing plate 43 near the right end. When the pressing plate 43 moves, the two groups of upper gaskets 44 will move synchronously. The baffle 41 is arranged in an L shape. The bottom end of another group of lower gaskets 45 is fixedly connected to the top end of the baffle 41. When the circuit passes through the top end of the baffle 41, it will be sealed and fixed once. At the same time, when the circuit leaves the inside of the fixing component 4, it will be sealed and fixed once again. Through the two sealing and fixing operations, the waterproof ability of the overall device at the rear end can be increased.

[0033] Refer to Figure 2 、 Figure 4 and Figure 5, the protection component 5 includes a fixed sleeve 51 for accommodating the overall protection component 5. The left end of the fixed sleeve 51 is fixedly connected to the inner wall of the protective sleeve 3. A slide rod 52 is slidably connected to the right end of the fixed sleeve 51. The slide rod 52 can move left and right within the inner wall of the fixed sleeve 51. A rubber block 53 for increasing the relative friction between the slide rod 52 and the fixed sleeve 51 is fixedly connected to the left end of the slide rod 52. By providing the rubber block 53, the minimum impact force required to drive the slide rod 52 to move can be increased, thus preventing the cover plate 2 from shaking driven by the vibration during the operation of the vehicle itself. The right end of the slide rod 52 is fixedly connected to the left end of the fixed shell 1. A protection spring 54 for pushing the rubber block 53 is fixedly connected to the left end of the rubber block 53. The left end of the protection spring 54 is fixedly connected to the inner wall of the fixed sleeve 51. The protection spring 54 will always push the rubber block 53 outward. Multiple groups of protection components 5 are provided. The left end of another group of protection components 5 is provided at the right end of the cover plate 2, and the right end of another group of protection components 5 is provided on the inner wall of the fixed shell 1 near the front end of the LED light row 7. When the cover plate 2 and the fixed shell 1 move relative to each other, multiple groups of protection components 5 will act simultaneously.

[0034] Working principle: When guiding the circuit, it is necessary to first arrange multiple wires in a row, then guide the wires through the wire groove 6 and over the baffle 41 from the top of the baffle 41. Then, cover the pressure plate 43 on the top of the bottom plate 42. The pressure plate 43 will drive two upper gaskets 44 to squeeze the wires to form two seals. After that, the pressure plate 43 and the bottom plate 42 can be fixed with bolts, and at this time the circuit is fixed.

[0035] When the cover plate 2 is subjected to a non-severe impact, the cover plate 2 will move to the right, and at the same time drive the fixed sleeve 51 to move towards the slide rod 52. At this time, the protection spring 54 will be compressed and contracted. When the cover plate 2 is not squeezed, the protection spring 54 will automatically extend and recover, and at the same time the protection spring 54 will push the fixed sleeve 51 to move it to the left. The leftward movement of the fixed sleeve 51 will push the cover plate 2 to move it to the left to reset, thus preventing the cover plate 2 from being damaged by compression.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
