Description

Technical Field

[0001] The invention relates to the technical field of electric vehicle headlights, and in particular to a vehicle headlight structure with adjustable lighting position and an adjustment method. Background Art

[0002] Electric vehicle headlights refer to the lighting devices installed on the front of the electric vehicle. It is one of the important safety components of the electric vehicle. Its main function is to provide the driver with sufficient lighting at night or in dimly lit environments to ensure driving safety. Headlights usually use high-efficiency light sources such as LEDs, which have the advantages of high brightness, low energy consumption and long life. It can not only illuminate the road ahead, helping the driver to find and avoid obstacles in time, but also transmit steering, braking and other signals to other road users through its light changes, thereby enhancing the visibility and safety of electric vehicles in traffic.

[0003] A Chinese patent with publication number CN222103455U discloses an LED car light with adjustable illumination angle, including a first rotating shaft, a gear fixedly connected to the middle of the first rotating shaft, a tooth groove provided at one end of the outer wall of the sphere, the gear being meshingly connected to the tooth groove, and the wick being driven to rotate when the sphere rotates, thereby adjusting the angle of light emitted by the wick. In this way, when a vehicle is coming from the opposite direction, the sphere can be driven to rotate by a motor, so that the light emitted by the wick can be tilted downward, so that the light emitted by the wick will not directly shine into the eyes of the driver in the opposite vehicle, so that the driver of the opposite vehicle can drive the vehicle normally, thereby ensuring traffic safety.

[0004] When the above patented angle-adjustable LED headlight is adjusted, the cable connected to the LED headlight at the rear end will reserve excess part for the LED headlight to rotate, and the reserved excess part has no restricting structure, which causes the cable to shake when the vehicle is running, affecting the stability of the connection. In addition, the shaking of the cable will also generate excess noise. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle headlight structure with adjustable lighting position and an adjustment method, which actively pushes the third limiting block through the resilience of the spring, so as to push the third limiting block to straighten the excess reserved cable, avoid affecting the rotation of the connecting disk, and improve the stability during use, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vehicle headlight structure with adjustable lighting position, comprising a connecting disk, a sleeve is arranged on the other side of the outside of the connecting disk, a cable is arranged laterally on the connecting disk toward the inside of the sleeve, a first limiting block is arranged at the middle position of the other side of the connecting disk, a second limiting block is arranged on the other side of the first limiting block, a third limiting block is arranged at the lower end between the second limiting block and the first limiting block, a transmission rod is arranged at the upper end of the third limiting block, a limiting ring is arranged at the upper end of the outside of the transmission rod, a spring is arranged inside the limiting ring, and sliding bars are arranged at the upper and lower ends of the outside of the connecting disk respectively toward the upper and lower ends of the inside of the sleeve.

[0007] Preferably, the cable is provided with a connecting ring fixed by glue near the connecting disk and the sleeve, and the connecting ring is provided with a bracket near the connecting disk and the sleeve.

[0008] Preferably, the bracket is fixed to the connecting ring by welding, and the bracket is fixedly connected to the connecting plate and the sleeve respectively by bolts.

[0009] Preferably, movable rails are recessed at the upper and lower ends of the interior of the sleeve, and the sliding bar is embedded in the movable rail and slidably connected with the interior of the sliding bar.

[0010] Preferably, a sliding rail is provided inside the sliding bar and is recessed toward the connecting disk, and protruding blocks are provided at the upper and lower ends of the connecting disk and are recessed toward the inside of the sliding rail, and the outside of the protruding blocks is connected to the internal slot of the sliding rail.

[0011] Preferably, a first limiting plate is provided at one end of the sliding bar, and a second limiting plate is provided at the other end of the sliding bar. Extension strips are provided at both the front and rear ends of the sliding bar, and the extension strips are embedded in the interior of the sleeve and slidably connected to the interior of the sleeve. The extension strip, the first limiting plate and the second limiting plate are all welded and fixed to the sliding bar.

[0012] Preferably, the first limiting plate has an upper end facing the sleeve with a first magnet fixed thereto by glue, and the sleeve is provided with a second magnet facing the first magnet and fixed thereto by glue, and the first magnet is magnetically connected to the second magnet.

[0013] Preferably, the lower end of the first limiting piece facing the protruding block is fixed with a third magnet by glue, and the protruding block is provided with a fourth magnet fixed with glue facing the third magnet, and the fourth magnet is magnetically connected to the third magnet.

[0014] A method for adjusting a vehicle headlight structure with adjustable lighting position comprises the following steps:

[0015] Step 1: The connecting plate rotates with the sleeve in the sleeve about the center of the rotating axis;

[0016] Step 2: The output shaft of the motor drives the gear to rotate, and the rotation of the gear engages with the tooth groove to actively adjust the direction of the connecting plate and the wick;

[0017] Step 3: The brackets at one end of the two connecting rings are close to and fit the sleeve and the connecting plate, and the bolts pass through the brackets and are embedded in the sleeve and the connecting plate;

[0018] Step 4: The cable pad is placed at the upper end outside the first limiting block and the second limiting block, and the cable pad between the first limiting block and the second limiting block is placed at the lower end outside the third limiting block. The extended transmission rod will straighten the cable between the first limiting block and the second limiting block.

[0019] Step 5: One of the protruding blocks slides on the sliding rail inside the corresponding sliding bar, and the other protruding block fits the corresponding sliding bar and pushes the sliding bar to slide in the movable rail;

[0020] Step 6. When the protruding block slides at the sliding rail position inside the sliding bar, the first limiting plate will fit the sleeve and limit the sliding bar. When the protruding block pushes the first limiting plate, the first limiting plate and the protruding block are magnetically connected through the third magnet and the fourth magnet, so that the first limiting plate extends out of the movable rail as the protruding block pushes.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When the gear of the present invention rotates outside the tooth groove to adjust the orientation of the connecting disk and the wick, the corresponding cable will be pulled through the bracket and the connecting ring. The position where the connecting ring pulls the cable is far away from the connection position between the cable and the connecting disk, which will not affect the connection position between the cable and the connecting disk and will not cause loose connection. The excess cable between the two connecting rings is supported by the transmission rod and the cable is straightened. After the connecting disk and the wick rotate, the third limiting block will be pulled and moved longitudinally upward to release the excess cable. The resilience of the spring will continue to push the third limiting block, continuously making the cable between the first limiting block and the second limiting block straight, thereby preventing the cable from shaking and generating noise.

[0023] 2. When the connecting disk of the present invention rotates in the sleeve with the rotating axis as the center, the tooth grooves will be exposed at the upper and lower ends of the outside of the sleeve. However, when the connecting disk rotates, the protruding block will push the sliding bar, so that the sliding bar slides and extends from the movable rail, and the extended sliding bar will continue to fill and cover the exposed tooth groove part. One of the protruding blocks pushes the sliding bar so that when one of the sliding bars covers the exposed tooth groove part, the other protruding block slides inside the sliding rail inside the other sliding bar. The sliding bars at the upper and lower ends inside the connecting disk fill and protect the exposed tooth groove part without affecting the rotation of the connecting disk.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figure 1 and Figure 6 As shown, a headlight structure with adjustable lighting position in this embodiment includes a connection disk 1, a wick 2 is arranged on one side of the outside of the connection disk 1, and lighting can be performed after the wick 2 is powered, and a sleeve 3 is arranged on the other side of the outside of the connection disk 1, and the sleeve 3 is rotatably connected to the connection disk 1 through a rotating shaft 4. When the direction of the connection disk 1 is adjusted, the connection disk 1 will drive the wick 2 to rotate with the rotating shaft 4 as the center of the circle;

[0037] Among them, a tooth groove 18 is provided at one end of the connection disk 1, which is recessed toward the position of the sleeve 3, and a gear 14 is provided at the middle position of one side of the outer side of the tooth groove 18. The outer part of the gear 14 is meshed and connected with the outer part of the tooth groove 18, and a motor is provided at one end of the gear 14. After the motor is started, the gear 14 can be driven to rotate, and the rotation of the gear 14 can drive the connection disk 1 to rotate;

[0038] In order to prevent the cable 26 reserved inside the sleeve 3 from shaking, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connection disk 1 is laterally provided with a cable 26 toward the inside of the sleeve 3, a first limiting block 6 is provided at the middle position of the other side of the connection disk 1, a second limiting block 7 is provided on the other side of the first limiting block 6, and a third limiting block 8 is provided at the lower end between the second limiting block 7 and the first limiting block 6. When the cable 26 is wound, the cable 26 will be padded on the upper ends of the first limiting block 6 and the second limiting block 7, and the cable 26 between the first limiting block 6 and the second limiting block 7 will be padded on the lower end outside the third limiting block 8. The third limiting block 8 will straighten the cable 26 when it moves longitudinally downward;

[0039] Among them, a transmission rod 9 is arranged at the upper end of the third limiting block 8, a limiting ring 10 is arranged at the upper end of the outer portion of the transmission rod 9, a spring 13 is arranged inside the limiting ring 10, and both ends of the spring 13 are respectively welded and fixed to the transmission rod 9 and the sleeve 3, and the resilience of the spring 13 will continue to push the transmission rod 9, so that the transmission rod 9 extends out from the limiting ring 10 and the third limiting block 8 moves longitudinally downward, so that the third limiting block 8 straightens the cable 26 between the first limiting block 6 and the second limiting block 7:

[0040] In addition, connecting rings 11 are respectively provided on both sides of the outside of the cable 26 close to the connecting disk 1 and the sleeve 3, and the inner wall of the connecting ring 11 is fixed to the outside of the cable 26 by glue, and the two connecting rings 11 are respectively provided with brackets 12 close to the connecting disk 1 and the sleeve 3, and the brackets 12 are welded and fixed to the connecting rings 11, and the brackets 12 are respectively fixedly connected to the connecting disk 1 and the sleeve 3 by bolts. After the bolts pass through the brackets 12 and fix the brackets 12, the connecting disk 1 will pull the cable 26 by the connecting rings 11 when it rotates, so as to prevent the connection between the connecting disk 1 and the cable 26 from being loosened due to pulling, and a pair of connecting rings 11 are respectively located on both sides of the spring 13, so that the rebound of the spring 13 is convenient for straightening the cable 26;

[0041] After the gear 14 rotates and causes the connection disk 1 to rotate, the tooth groove 18 will be exposed outside the sleeve 3. In order to prevent the exposed tooth groove 18 from contacting external foreign objects, sliding bars 15 are provided at the upper and lower ends of the outer side of the connection disk 1 facing the upper and lower ends of the inner side of the sleeve 3, respectively. The upper and lower ends of the inner side of the sleeve 3 are recessed with movable rails 25, and the sliding bar 15 is embedded in the inner side of the movable rail 25 and is slidably connected to the inner side of the sliding bar 15. The sliding bar 15 slides in the movable rail 25 to cover and wrap the exposed tooth groove 18.

Extension bars 16 are provided at both the front and rear ends of the sliding bar 15, and the extension bar 16 is embedded in the sleeve 3 and slidably connected to the inside of the sleeve 3. When the sliding bar 15 rotates in the sleeve 3, the second limiting piece 17 and the first limiting piece 5 will limit and prevent the sliding bar 15 from falling off. The extension bar 16, the first limiting piece 5 and the second limiting piece 17 are respectively welded and fixed to the outer wall of the sliding bar 15;

[0044] Among them, the first limiting plate 5 is provided with a first magnet 21 at the upper end of the side facing the sleeve 3, and the first magnet 21 is fixed to the first limiting plate 5 by glue, and the sleeve 3 is provided with a second magnet 22 facing the first magnet 21, and the second magnet 22 is fixed to the sleeve 3 by glue, and the first magnet 21 is magnetically connected to the second magnet 22.

[0046] A method for adjusting a vehicle headlight structure with adjustable lighting position comprises the following steps:

[0047] Step 1: The connecting disk 1 is clamped inside the sleeve 3 and is rotatably connected to the inside of the sleeve 3 through the rotating shaft 4, the tooth groove 18 inside the connecting disk 1 is meshed and connected with the outside of the gear 14, and the motor corresponding to the gear 14 is started;

[0048] Step 2: The output shaft of the motor drives the gear 14 to rotate, and the rotation of the gear 14 meshes with the tooth groove 18 to actively adjust the orientation of the connecting plate 1 and the wick 2;

[0049] Step 3: Both sides of the outer side of a reserved cable 26 between the connection plate 1 and the inner wall of the sleeve 3 are glued with the connection ring 11, and the brackets 12 at one end of the two connection rings 11 are close to and fit the sleeve 3 and the connection plate 1, and the bolts pass through the brackets 12 and are embedded in the sleeve 3 and the connection plate 1;

The spring 13 pushes the transmission rod 9 to extend from the outside of the limiting ring 10. The extended transmission rod 9 pushes the third limiting block 8 and straightens the cable 26 between the first limiting block 6 and the second limiting block 7.

[0051] Step 5: The connecting plate 1 rotates with the rotating shaft 4 as the center, while driving the protruding blocks 19 at the upper and lower ends to rotate, one of the protruding blocks 19 slides on the sliding rail 20 inside the corresponding sliding bar 15, and the other protruding block 19 fits the corresponding sliding bar 15 and pushes the sliding bar 15 to slide in the movable rail 25;

[0052] Step six, when the protruding block 19 slides at the position of the sliding rail 20 inside the sliding bar 15, the first limiting plate 5 will fit the sleeve 3 and limit the sliding bar 15. When the protruding block 19 pushes the first limiting plate 5, the first limiting plate 5 and the protruding block 19 are magnetically connected through the third magnet 23 and the fourth magnet 24, so that the first limiting plate 5 extends out of the movable rail 25 as the protruding block 19 pushes, so that the sliding bar 15 wraps and protects the exposed tooth groove 18.
