[0001] The utility model relates to the technical field of LED automobile lamps, in particular to an adjustable automobile LED headlight. Background Art

[0002] LED car lights refer to the use of LED technology for both internal and external light sources in the car, which are used for external and internal lighting and are suitable for various lighting applications in automotive electronics, including headlights, headlights, brake lights, turn signal lights, pedal lights, instrument lights, backlights and indicator lights.

[0003] In addition, the optimal light source position of different models of car headlight assemblies is slightly different, resulting in the same LED headlight on the market being incompatible with all models and not being able to achieve the best lighting effect. Therefore, after some models are replaced with LED headlights, the low beam is dazzling to oncoming vehicles and pedestrians, the high beam is not focused, and the illumination distance is short, which increases traffic safety risks for drivers and others.

[0004] To this end, an adjustable automotive LED headlight is proposed, so that the LED headlight with this function can be adapted to almost all halogen lamp models, optimize the lighting effect of the LED headlight, and improve the driving and road traffic safety of the car. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an adjustable automobile LED headlight.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an adjustable automotive LED headlight, comprising an automotive LED lamp body and an LED lamp chuck, and also comprising:

[0007] An adjustment structure is provided on the LED lamp chuck for adapting to different sizes of automobile headlight slots;

[0008] Among them, the adjustment structure includes a ring and a gasket, the gasket is sleeved on the outer surface of the LED lamp card, three groups of extrusion parts are installed on the outside of the gasket, a movable rod is sleeved inside the LED lamp card, a protrusion and an arc plate are respectively installed at both ends of the movable rod, and a first spring is sleeved on the outer surface of the movable rod.

[0009] As mentioned above, a pull rod is installed on the outer surface of the gasket, a slide groove is opened on the outer side of the LED lamp chuck, a cavity is opened inside the pull rod, a fixing rod is installed inside the cavity, and a second spring and a limit block are sleeved on the outer surface of the fixing rod.

[0010] As mentioned above, a fixed baffle is sleeved on the outer side of the LED lamp chuck, and a fixed clamping tooth is installed on one side of the fixed baffle.

[0011] As mentioned above, the extrusion piece is arc-shaped, and the extrusion piece is in extrusion contact with the arc-shaped plate.

[0012] As mentioned above, the first spring is elastically supported between the LED lamp clamp and the arc plate.

[0013] As mentioned above, when the extrusion piece extrudes the arc-shaped plate, the protrusion can be engaged with the lamp groove of the automobile headlight.

[0014] As mentioned above, the end of the pull rod is corrugated, and the pull rod is slidably matched with the slide groove.

[0015] As mentioned above, the second spring is elastically supported between the cavity and the limiting block.

[0016] As mentioned above, the top of the limit block is tooth-shaped, and the limit block is movably engaged with the fixed locking teeth.

[0017] As mentioned above, when the pull rod moves along the inner side of the slide groove, it can drive the gasket to rotate, the automobile LED lamp body is sleeved on the inner wall of the LED lamp chuck, and the outer side of the automobile LED lamp body is inlaid with a ring, and the ring is set at the bottom of the LED lamp chuck.

[0018] Compared with the prior art, this adjustable automotive LED headlight has the following beneficial effects:

[0019] 1. The utility model enables the gasket to rotate along the inner wall of the LED lamp chuck through the cooperation between the gasket and the extrusion piece.

[0020] 2. The utility model enables the pull rod to move along the inner side of the slide groove through the cooperation between the pull rod and the slide groove, so that the gasket can be driven by the pull rod to move along the inner wall of the LED lamp chuck. At the same time, since the second spring is in a compressed state, it will exert an elastic force on the limit block and limit the pull rod through the cooperation between the limit block and the fixed tooth. Then, the downward movement of the protrusion can be limited by the extrusion piece, making it more stable when assembled with the automobile headlight groove.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-6 As shown, the utility model provides an adjustable automotive LED headlight, comprising an automotive LED lamp body 1 and an LED lamp chuck 2, and also comprising:

[0033] An adjustment structure, which is arranged on the LED lamp chuck 2 and is used to adapt to the lamp slots of automobile headlights of different sizes;

[0034] Among them, the adjustment structure includes a ring and a gasket, the gasket 3 is sleeved on the outer surface of the LED lamp chuck 2, three groups of extrusion parts 4 are installed on the outside of the gasket 3, a movable rod 5 is sleeved inside the LED lamp chuck 2, and a protrusion 6 and an arc plate 7 are respectively installed at both ends of the movable rod 5, and a first spring 8 is sleeved on the outer surface of the movable rod 5.

[0035] Through the cooperation between the gasket 3 and the extrusion piece 4, the gasket 3 can rotate along the inner wall of the LED lamp chuck 2. At the same time, through the cooperation between the extrusion piece 4 and the arc plate 7, since the extrusion piece 4 is arc-shaped, when the extrusion piece 4 squeezes the arc plate 7, the movable rod 5 will be driven by the arc plate 7 to move along the inside of the LED lamp chuck 2, so that the protrusion 6 can be extended by the movable rod 5, so that it can be adapted to the diameter of the automobile headlight groove.

[0036] like Figure 5 , 6 As shown, a pull rod 9 is installed on the outer surface of the gasket 3, a slide groove 16 is opened on the outer side of the LED lamp chuck 2, a cavity 10 is opened inside the pull rod 9, a fixing rod 11 is installed inside the cavity 10, and a second spring 12 and a limit block 13 are sleeved on the outer surface of the fixing rod 11.

[0037] Through the cooperation between the pull rod 9 and the slide groove 16, the pull rod 9 can move along the inner side of the slide groove 16, so that the gasket 3 can be driven by the pull rod 9 to move along the inner wall of the LED lamp chuck 2. At the same time, since the second spring 12 is in a compressed state, it will exert an elastic force on the limit block 13, and then the pull rod 9 can be limited by the cooperation between the limit block 13 and the fixed tooth 15.

[0038] like Figure 3 As shown, a fixed baffle 14 is sleeved on the outer side of the LED lamp chuck 2 , and a fixed tooth 15 is installed on one side of the fixed baffle 14 .

[0039] Through the design of the fixed tooth 15, the pull rod 9 can be limited by the cooperation between the limit block 13 and the fixed tooth 15. At the same time, through the cooperation between the limit block 13 and the fixed rod 11, the limit block 13 can move downward along the outer surface of the fixed rod 11 and separate from the fixed tooth 15, thereby releasing the limit on the pull rod 9.

[0040] like Figure 4 As shown, the extrusion piece 4 is arc-shaped, and the extrusion piece 4 is in extrusion contact with the arc-shaped plate 7.

[0041] Through the arc-shaped design of the extrusion piece 4, when the extrusion piece 4 squeezes the arc plate 7, the movable rod 5 will be driven by the arc plate 7 to move along the inside of the LED lamp chuck 2, so that the protrusion 6 can be driven by the movable rod 5 to move, so that it can be extended and adapted to the lamp groove of the automobile headlight.

[0042] like Figure 4 As shown, the first spring 8 is elastically supported between the LED lamp chuck 2 and the arc plate 7 .

[0043] Through the design of the first spring 8, the arc plate 7 has good elastic reset performance. At this time, since the first spring 8 is in a compressed state, it will apply an elastic force to the arc plate 7, so that when the extrusion member 4 releases the extrusion on the arc plate 7, it will drive the protrusion 6 to reset.

[0044] like Figure 4 As shown, when the extrusion piece 4 squeezes the arc plate 7, the projection 6 can be engaged with the lamp groove of the automobile headlight.

[0045] Through the design of the extrusion member 4, when it extrudes the arc plate 7, the projection 6 will be driven to move through the movable rod 5, so that the projection 6 can be driven to cooperate with the lamp groove of the automobile headlight.

[0046] like Figure 3 As shown, the end of the pull rod 9 is corrugated, and the pull rod 9 is slidably matched with the slide groove 16.

[0047] Through the design of the pull rod 9, since the end of the pull rod 9 is corrugated, it is convenient for the staff to control the movement of the pull rod 9. At the same time, through the cooperation between the pull rod 9 and the slide groove 16, when the pull rod 9 is pushed, the pull rod 9 will move along the inner side of the slide groove 16.

[0048] like Figure 6 As shown, the second spring 12 is elastically supported between the cavity 10 and the limiting block 13 .

[0049] Through the design of the second spring 12, the limit block 13 has good elastic reset performance. At this time, since the second spring 12 is in a compressed state, an elastic force is applied to the limit block 13, so that the fit between the limit block 13 and the fixed tooth 15 is tighter.

[0050] like Figure 2 , 6 As shown, the top of the limiting block 13 is tooth-shaped, and the limiting block 13 is movably engaged with the fixed locking teeth 15 .

[0051] Through the cooperation between the limit block 13 and the fixing rod 11, the limit block 13 can move up and down along the outer surface of the fixing rod 11. At the same time, through the cooperation between the limit block 13 and the fixing tooth 15, the pull rod 9 will be limited, thereby positioning the gasket 3.

[0052] like Figure 2 , 5 As shown, when the pull rod 9 moves along the inner side of the slide groove 16 , it can drive the gasket 3 to rotate, and the automotive LED lamp body 1 is sleeved on the inner wall of the LED lamp chuck 2 .

[0053] The movement of the gasket 3 is controlled by the pull rod 9. When the pull rod 9 remains in a fixed state, the gasket 3 will also be limited, so that the arc plate 7 can be limited to move downward by the extrusion piece 4, and then the protrusion 6 can be limited, making it more stable when assembled with the automobile headlight groove.

[0054] like Figure 7 As shown, a ring 17 is inlaid on the outer side of the automotive LED lamp body 1 , and the ring 17 is arranged at the bottom of the LED lamp chuck 2 .

[0055] By increasing or decreasing the ring 17, the height of the LED headlight chuck 2 can be driven, thereby changing the position of the LED headlight light source in the automobile headlight assembly to match the headlight assemblies of different models, so that the LED headlight light source is closer to the optimal optical point of the headlight assembly, changing the optics of the LED headlight, and achieving the best automobile headlight lighting effect. The specific operations are as follows:

[0056] If the device is used for the reflective bowl of the headlamp assembly, there is no need to add the ring 17 to the LED headlamp, and the bulb can be directly installed; if it is a lens, remove and take out the LED headlamp chuck 2 by rotating it clockwise, add the ring 17 to the car LED lamp body 1, then install the LED headlamp chuck 2 back to the lamp body 1, and finally install the LED headlamp into the car headlamp assembly.

[0057] In other cases where the lighting effect is not good, the above method can be used to increase or reduce the ring 17 to improve the optical effect of the LED headlight.

[0058] Working principle:

[0059] First, the staff can press the limit block 13 to move along the outer surface of the fixed rod 11 to separate it from the fixed tooth 15, and then the staff can push the pull rod 9 to move. Through the cooperation between the gasket 3 and the extrusion piece 4, the gasket 3 will be driven to rotate along the inner wall of the LED lamp chuck 2. At the same time, through the cooperation between the extrusion piece 4 and the arc plate 7, since the extrusion piece 4 is arc-shaped, when the extrusion piece 4 squeezes the arc plate 7, the movable rod 5 will be driven to move along the inside of the LED lamp chuck 2 through the arc plate 7, so that the protrusion 6 can be extended through the movable rod 5, and then it can be adapted to the diameter of the automobile headlight trough, and finally the automobile LED lamp body 1 can be assembled through the cooperation between the automobile LED lamp body 1 and the LED lamp chuck 2. By increasing or decreasing the ring 17, the height of the LED headlight chuck 2 can be driven, thereby changing the position of the LED headlight light source in the automobile headlight assembly to match the headlight assemblies of different models, so that the LED headlight light source is closer to the best optical point of the headlight assembly, changing the optics of the LED headlight, and achieving the best automobile headlight lighting effect.
