Description

Technical Field

[0001] This utility model relates to the field of unmanned vehicle technology, and in particular to a lighting adjustment device for autonomous unmanned vehicles. Background Technology

[0002] Unmanned vehicles, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are intelligent vehicles that achieve driverless operation through computer systems. They rely on the collaborative efforts of artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems to enable computers to automatically and safely operate motor vehicles without any human intervention. [1] The environmental perception system of autonomous vehicles is the key to ensuring their safe and autonomous driving. This system integrates a variety of advanced sensor technologies and data processing methods to acquire environmental information around the vehicle in real time and accurately. Specifically, the environmental perception system uses a variety of sensors such as LiDAR, camera, and millimeter-wave radar to conduct comprehensive and high-precision monitoring and identification of roads, pedestrians, other vehicles, traffic signs, obstacles, etc. around the vehicle.

[0003] Currently, autonomous vehicles use cameras to detect road environment information while driving on the road. When the light is dim, they turn on the headlights to increase the clarity of the cameras and ensure driving safety. However, the lighting structure on the autonomous vehicle does not turn off automatically when meeting oncoming traffic. This causes the headlights to shine directly into the eyes of the drivers of oncoming vehicles, thus affecting the safety of meeting oncoming traffic. Utility Model Content

The lighting assembly includes a fixed frame, a servo motor is fixedly connected to the inner wall of the fixed frame, and a rotating shaft is fixedly connected to the output end of the servo motor. A rotating groove is formed on the right side of the vehicle body, a positioning shaft is fixedly connected to the inner wall of the rotating groove, a transmission block is rotatably connected to the surface of the positioning shaft, a lamp frame is fixedly connected to the right side of the transmission block, a slot is formed on the right side of the lamp frame, a lighting lamp is inserted into the inner wall of the slot, an arc-shaped meshing plate is fixedly connected to the left side of the transmission block, and a transmission gear is fixedly connected to the surface of the rotating shaft.

[0007] Preferably, the end of the rotating shaft away from the servo motor extends into the interior of the unmanned vehicle body and is rotatably connected to the inner rear wall of the unmanned vehicle body.

[0008] Preferably, the position of the transmission gear corresponds to the position of the arc-shaped meshing plate, and the transmission gear meshes with the inner wall of the arc-shaped meshing plate.

[0009] Preferably, a maintenance component is fixedly connected to the upper surface of the lamp frame. The maintenance component includes a strip frame. A strip-shaped through hole is opened on the upper surface of the lamp frame at a position corresponding to the strip frame. A circular hole is opened on the front side of the strip frame. A positive and negative threaded rod is rotatably connected to the inner rear wall of the strip frame. An internal hexagonal nut is fixedly connected to the front end of the positive and negative threaded rod, and the position of the internal hexagonal nut corresponds to the position of the circular hole.

[0010] Preferably, the inner top wall of the strip frame is slidably connected to two sliders, and the two sliders are respectively threaded to the positive and negative threads on the surface of the positive and negative threaded rod.

This significantly improves maintenance efficiency and flexibility. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] Reference Figure 1-4 A lighting adjustment device for an autonomous vehicle includes an autonomous vehicle body 1, a lidar 2 fixedly connected to the upper surface of the autonomous vehicle body 1, a camera 3 fixedly connected to the right side of the autonomous vehicle body 1, a lighting assembly fixedly connected to the front of the autonomous vehicle body 1, the lighting assembly including a fixed frame 4, a servo motor 5 fixedly connected to the inner wall of the fixed frame 4, a rotating shaft 6 fixedly connected to the output end of the servo motor 5, a rotating groove opened on the right side of the autonomous vehicle body 1, a positioning shaft 7 fixedly connected to the inner wall of the rotating groove, a transmission block 8 rotatably connected to the surface of the positioning shaft 7, a lamp frame 9 fixedly connected to the right side of the transmission block 8, a slot opened on the right side of the lamp frame 9, a lighting lamp 10 inserted into the inner wall of the slot, an arc-shaped meshing plate 11 fixedly connected to the left side of the transmission block 8, and a transmission gear 12 fixedly connected to the surface of the rotating shaft 6.

[0023] The end of the rotating shaft 6 away from the servo motor 5 extends into the interior of the unmanned vehicle body 1 and is rotatably connected to the inner rear wall of the unmanned vehicle body 1. The position of the transmission gear 12 corresponds to the position of the arc-shaped meshing plate 11, and the transmission gear 12 meshes with the inner wall of the arc-shaped meshing plate 11.

[0024] When the unmanned vehicle body 1 is driving normally, the light frame 9 can drive the lighting lamp 10 to illuminate the road on which the unmanned vehicle is driving, thereby increasing the clarity of the camera 3 and ensuring driving safety. In addition, when the camera 3 detects an oncoming vehicle and is about to meet it, the controller inside the unmanned vehicle body 1 automatically turns on the servo motor 5, and drives the rotating shaft 6 to rotate through the servo motor 5. The rotating shaft 6 can drive the transmission gear 12 to rotate, and through the arc meshing plate 11, drive the transmission block 8 to rotate on the surface of the positioning shaft 7. The transmission block 8 can drive the light frame 9 to rotate downward, thereby shifting the illumination angle of the lighting lamp 10 downward, avoiding direct illumination of the eyes of the driver of the oncoming vehicle. At this time, the camera 3 of the unmanned vehicle is limited by the illumination range and slows down, increasing the safety of meeting oncoming vehicles.

[0025] A maintenance assembly is fixedly connected to the upper surface of the lamp frame 9. The maintenance assembly includes a strip frame 13. A strip-shaped through hole is opened on the upper surface of the lamp frame 9 at a position corresponding to the strip frame 13. A circular hole is opened on the front side of the strip frame 13. A positive and negative threaded rod 14 is rotatably connected to the inner rear wall of the strip frame 13. An internal hexagonal nut 15 is fixedly connected to the front end of the positive and negative threaded rod 14, and the position of the internal hexagonal nut 15 corresponds to the position of the circular hole. Two sliders 16 are slidably connected to the inner top wall of the strip frame 13, and the two sliders 16 are respectively connected to the positive and negative threaded rods. The rod 14 is threaded at the positive and negative threads on its surface. The lower surfaces of the two sliders 16 are fixedly connected with inclined blocks 17. The two sliders 16 are slidably connected to the inner wall of the strip-shaped through hole. The left side of the lighting lamp 10 is fixedly connected with a positioning block 18, which is adapted to the slot. The positioning block 18 has positioning grooves on its front and back sides. The two inclined blocks 17 are slidably connected to the inner wall of the slot. The opposite sides of the two inclined blocks 17 are fixedly connected with locking blocks 19, which are adapted to the two positioning grooves respectively.

[0026] When installing the lighting lamp 10, first insert the lighting lamp 10 into the slot on the right side of the lamp frame 9 through the positioning block 18 on the left. At this time, use an Allen wrench to insert into the Allen nut 15 and drive the forward and reverse threaded rod 14 to rotate clockwise, thereby driving the two sliders 16 to move closer to each other. The two sliders 16 can drive the two locking blocks 19 to move closer to each other through the two tilting blocks 17 until the two locking blocks 19 are inserted into the two positioning slots on the front and back of the positioning block 18, thereby locking the position of the lighting lamp 10. When maintenance or replacement is required, simply insert the Allen wrench and drive the Allen nut 15 to rotate counterclockwise to remove the lighting lamp 10 from the lamp frame 9, which greatly improves maintenance efficiency.

[0027] Working principle: First, during the autonomous driving process of the unmanned vehicle, the light frame 9 drives the lighting lamp 10 to illuminate the road where the unmanned vehicle is traveling, thereby improving the image clarity of the camera 3 and increasing driving safety. When a vehicle is approaching from the opposite lane, the camera 3 automatically detects the approaching vehicle. At this time, the unmanned vehicle body 1 automatically activates the servo motor 5 through the internal industrial control host. The servo motor 5 drives the transmission gear 12 to rotate through the rotating shaft 6, which in turn drives the transmission block 8 to rotate on the surface of the positioning shaft 7 through the arc-shaped meshing plate 11. This, in turn, causes the light frame 9 to rotate downward, preventing the lighting lamp 10 from directly illuminating the driver in the front of the oncoming vehicle. This allows the lighting lamp 10 to be shifted downward. At the same time, the unmanned vehicle body... Body 1 decelerates, increasing safety when passing other vehicles. In addition, when the lighting lamp 10 needs to be replaced or repaired, first use a hex wrench to insert into the internal hex nut 15 and drive it to rotate. The internal hex nut 15 can drive the threaded rod 14 to rotate counterclockwise. After the threaded rod 14 rotates counterclockwise, it can drive the two sliders 16 to move away from each other. At this time, the two sliders 16 can drive the two locking blocks 19 to move away from each other through the tilting block 17. At this time, the two locking blocks 19 simultaneously disengage from the positioning grooves on both sides of the positioning insert 18, so that the lighting lamp 10 is no longer restricted in the slot, and can be quickly pulled out from the lamp frame 9, which greatly improves the efficiency of maintenance and replacement of the lighting lamp 10 and has high flexibility.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
