[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] As shown in Figure 1- Figure 6 As shown, this utility model provides a technical solution: a lighting device that facilitates adjustment of the lighting range, comprising: a lamp body 1, a protective mechanism 2 on one side of the lamp body 1, a rotating mechanism 3 inside the protective mechanism 2, a pushing mechanism 4 on one side of the rotating mechanism 3, the rotating mechanism 3 including a rotating ring 31, two semi-circular plates 32 symmetrically fixedly connected to the inner side of the rotating ring 31, four semi-circular plates 33 equidistantly fixedly connected to the inner side of the rotating ring 31, a pressing plate 34 slidably connected to one side of each of the semi-circular plates 33, a pushing plate 35 fixedly connected to the side of the pressing plate 34 away from the semi-circular plates 33, a fixing plate 36 on the top of the pushing plate 35, a spring 37 fixedly connected to one side of the fixing plate 36, a fixing block 38 fixedly connected to the side of the spring 37 away from the fixing plate 36, and two fixing posts 39 slidably connected to the top of the pushing plate 35 through a sliding connector.

[0021] In this embodiment, a slot 25 is provided in the middle of the outer side of the housing 21. A slide plate 26 is fixedly connected to the outer side of the rotating ring 31. Slot teeth 27 are provided on both sides of the slide plate 26. The slot teeth 27 are triangular in shape. A small inverted triangular catch corresponding to the slot teeth 27 is fixedly connected inside the slot 25. The outer side of the slide plate 26 is slidably connected to the inside of the slot 25. Moving the slide plate 26 left and right will cause the rotating ring 31 to rotate. The slide plate 26 moves towards the side corresponding to the inclined surface of the slot teeth 27. The outer inclined surface of the slot teeth 27 presses against the inclined surface of the catch block inside the slot 25. The downward pressing force causes the spring 38 in the middle to contract, thereby allowing the slot 25 to move normally. If an external force moves the slide plate... When plate 26 moves in the opposite direction, the plane of the locking tooth 27 contacts the locking block inside the slot 25, generating a squeezing force on both sides. This squeezing force is not affected by the spring contraction; it only restricts the slide plate 26 from reversing. To reverse the slide plate 26, the buttons 29 on both sides of the slide plate 26 need to be pressed to compress the spring 3 28 in the middle. The spring 3 28 retracts the locking tooth 27 into the slide plate 26, thus releasing the restriction and reversing the slide plate 26. This effectively prevents accidental contact with the slide plate 26 from causing a sudden change in the lighting range. Four semi-circular plates 2 33 are fixedly connected to the inner side of the rotating ring 1 31. Rotating the rotating ring 1 31 will cause the semi-circular plates 2 33 to rotate. A squeezing plate 1 34 is provided on one side of the semi-circular plates 2 33. One side of the squeezing plate 1 34 is slidably connected to the inner side of the semi-circular plates 2 33. The inner side of the semi-circular plates 2 33 is semi-circular. Rotating the inner side of the semi-circular plates 2 33 will squeeze one side of the squeezing plate 1 34, thereby causing the squeezing plate 1 34 to move forward. A pulley is provided on the side near the semicircular plate 33 to reduce the friction between the side of the extrusion plate 34 and the inner side of the semicircular plate 33. The four extrusion plates 34 move forward to block the lighting part of the lighting equipment, thereby achieving free adjustment of the lighting range. A fixing block 38 is fixedly connected to the top of the extrusion plate 34. A spring 37 is fixedly connected to one side of the fixing block 38. A fixing plate 36 is fixedly connected to the side of the spring 37 away from the fixing block 38. One side of the fixing plate 36 is fixedly connected to the outer side of the connecting ring 23. The elastic contraction of the spring 37 can help the push plate 35 return to its original position to meet the adjustment needs of different lighting ranges. A fixing post 39 is slidably connected to the top of the push plate 35 through a connector. The side of the fixing post 39 away from the push plate 35 is fixedly connected to the outer side of the connecting ring 24. The fixing post 39 supports the push plate 35 and limits its forward and backward movement, thereby allowing the push plate 35 to move freely. It does not tilt, it only moves back and forth. Example 2

[0022] As shown in Figure 1- Figure 6 As shown, the propulsion mechanism 4 includes a rotating ring 41. Two semi-circular plates 42 are symmetrically fixedly connected to the inner side of the rotating ring 41. A pressing plate 43 is slidably connected to one side of each of the semi-circular plates 42. A propulsion plate 44 is fixedly connected to the side of the pressing plate 43 away from the semi-circular plates 42. A spring 45 is fixedly connected to one side of the propulsion plate 44. A fixing block 46 is fixedly connected to the side of the spring 45 away from the propulsion plate 44. Two limiting posts 47 are respectively provided on both sides of the top of the propulsion plate 44. A pressing post 48 is rotatably connected to the bottom of the propulsion plate 44 through a bearing connector. The bottom end of the limiting post 47 is fixed... The fixed connection is equipped with a rotating bearing 49.

[0023] In this embodiment, one side of the slide plate 26 is fixedly connected to the outer side of the rotating ring 41. Two semicircular plates 42 are fixedly connected to the inner side of the rotating ring 41. Rotating the rotating ring 41 will cause the semicircular plates 42 to rotate. A pressing plate 43 is slidably connected to one side of the semicircular plates 42. The rotation of the semicircular plates 42 will press one side of the pressing plate 43 forward. The side of the pressing plate 43 away from the semicircular plates 42 is fixedly connected to one corner of the pushing plate 44. A limiting post 47 is provided at the top of the pushing plate 44. A rotating bearing 49 is fixedly connected to the bottom of the limiting post 47. A groove is provided at the top of the pushing plate 44 so that the rotating bearing 49 can move within it. The rotating bearing 49 allows for free adjustment of its angle. The limiting post 47 provides effective support and limits the movement of the pushing plate 44, making the entire process more stable. The forward movement of the pressing plate 43 will push the pushing plate 44 forward, but because the pressing plate 43... The pushing angle is too large, so it will not push the second push plate 44 forward, but will only change the angle. A second spring 45 is fixedly connected to one side of the second push plate 44. The end of the second spring 45 away from the second push plate 44 is fixedly connected to one side of the second fixing block 46. The top of the second fixing block 46 is fixedly connected to the bottom of the top cover 22. When the second push plate 44 needs to be reset to adjust the lighting range, the elastic force of the second spring 45 contracts to reset the second push plate 44. The bottom of the second push plate 44 is rotatably connected to the extrusion column 48 through the connector. The extrusion column 48 is in the shape of an inverted L. The bottom of the extrusion column 48 is slidably connected to the inner side of the semicircular plate 32. When the semicircular plate 32 rotates, it will extrude the extrusion column 48 and move it forward. The forward movement of the extrusion column 48 will push one side of the propulsion plate 44 forward a short distance, and the angle will change again, thereby realizing the forward tilting movement of the propulsion plate 44. The two propulsion plates 44 cover part of the area of ​​the lighting equipment illuminating the vehicle, so that the light reflected by the lighting equipment is trapezoidal and the light has a converging effect.

[0024] Working principle: The lamp body 1 is responsible for generating the light source, and the housing 21 is responsible for protecting the internal components from impact damage and extending the service life of the mechanism. When it is necessary to reduce the lighting range, slide plate 26 is moved to one side. Slide plate 26 drives the rotating ring 31, which is fixedly connected inside, to rotate. The rotation of rotating ring 31 will drive the semicircular plate 33 to rotate. The semicircular plate 33 is semicircular. When the semicircular plate 33 rotates, its inner side will squeeze one side of the pressing plate 34. The pressing plate 34 is squeezed and moves forward. The forward movement of the pressing plate 34 will push one side of the fixed connection. The push plate 35 moves forward, and one side of the spring 37 is fixedly connected to the outside of the connecting ring 24. The side of the spring 37 away from the connecting ring 24 is slidably connected to the top of the push plate 35 through a connector, supporting and restricting the push plate 35 so that the push plate 35 only moves back and forth. The four push plates 35 move forward at the same time to block the illumination part of the lighting equipment, thereby reducing the lighting range. When it is necessary to increase the lighting range, the slide plate 26 needs to be reversed. Press the buttons 29 on both sides of the slide plate 26 to force the spring 3 28 in the middle to contract, thereby causing the locking teeth 27 to retract into the slide plate 26. Then the slide plate 26 is reversed again. Slide 26 drives the rotating ring 31 to reverse, which in turn drives the semicircular plate 32 to reverse. The reverse rotation of the semicircular plate 32 will reduce the squeezing force on one side of the semicircular plate 33. At this time, the top spring 37 contracts and pulls back the push plate 35. All four push plates 35 retract simultaneously, and the lighting equipment loses its obstruction, thereby increasing the lighting range. Moving the slide 26 fixedly connected to the outside of the rotating ring 41 causes the rotating ring 41 to rotate. The rotation of the rotating ring 41 drives the semicircular plate 42 to rotate. The rotation of the semicircular plate 42 squeezes one side of the squeezing plate 43, causing the squeezing plate 43 to move forward. The squeezing plate 43 is located at one corner of the push plate 44. The forward movement of the squeezing plate 43 pushes one corner of the push plate 44 forward. The angle of the squeezing plate 43 is too large, so only the angle of the push plate 44 changes. The limiting post 47 and the rotating bearing 49 can be used for the push plate 44. Providing effective support and angle adjustment, the bottom of the second propeller plate 44 is rotatably connected to a pressing column 48 via a connector. The side of the pressing column 48 away from the second propeller plate 44 is slidably connected to the outer side of the first semicircular plate 32. The first semicircular plate 32 is fixedly connected to the inner side of the first rotating ring 31. The rotation of the first rotating ring 31 will drive the first semicircular plate 32 to rotate, and the rotation of the first semicircular plate 32 will press the pressing column 48 forward. The top of the second propeller plate 44 is provided with a limiting column 47. One side of the limiting column 47 is fixedly connected to the outer side of the first connecting ring 23, and the side of the limiting column 47 away from the first connecting ring 23 is rotatably connected to the pressing column 48 via a connector, allowing the second propeller plate 44 to rotate freely. The movement of the pressing column 48 will push one corner of the second propeller plate 44 forward. When the original angle changes, the other side moves forward to reduce the angle, thereby causing the second propeller plate 44 to shift as a whole and change its own angle. The two second propeller plates 44 By partially blocking the light, a trapezoidal effect is created in the illuminated area. The light emitted by the lighting equipment is narrower at the bottom and wider at the top. As the distance of the illumination increases, the illuminated area expands, thus achieving the trapezoidal lighting effect. The light can be focused, and users can adjust the focus to create a more diverse range of light to meet different needs.
