Description

Technical Field

[0001] This utility model relates to the field of light guidance technology, and in particular to a light guidance device for a smart parking lot. Background Technology

[0002] Parking guidance systems are mainly suitable for large and medium-sized underground parking lots and are widely used in public parking lots such as government office buildings, large hospitals, train stations, and shopping malls. Their main working principle is based on ultrasonic detectors emitting ultrasonic waves from top to bottom to detect the reflected waves from the roof and ground. This allows them to accurately detect whether there is a vehicle in each parking space. The parking status information of each space is then transmitted to the control computer via network lines. The computer processes the information through software and sends guidance signals to the guidance indicator, which guides the driver to quickly find an available space.

[0020] This utility model provides, for example Figures 1-4The illustrated light guidance device for a smart parking lot includes a work box 1. An infrared alignment light 2 is fixedly connected to one side of the top surface of the work box 1. The interior of the work box 1 has an extension mechanism 3 that can extend outwards to both sides, automatically adjusting the extension according to the vehicle size. Light guidance mechanisms 4 are located on both sides of the work box 1's surface at the extension mechanism 3, illuminating the bottom surface to guide the vehicle for precise parking. A rotating structure 5 is located at the bottom of the work box 1. In use, this device first uses the infrared alignment light 2 to detect the lateral width of the vehicle and makes appropriate adjustments accordingly. Then, the sliding plate 304 is lowered by the electric telescopic rod 303, and the extension blocks 308 on both sides of the work box 1 are extended equally according to the width of the vehicle. Then, the multiple illumination lights 405 on both sides emit linear lights, which then illuminate the reflectors 407 on the bottom surface of the inclined plate 406, and bounce off the ground. The reflectors are located on the left and right sides of the car, which makes it convenient for the driver to park accurately. While parking accurately, the driver will not hit other buildings, and the guiding device will not obstruct the driver's view, effectively reducing safety hazards and avoiding damage to the car.

[0021] like Figure 2 As shown, the extension mechanism 3 includes an extension cavity 302, an electric telescopic rod 303, and a sliding plate 304. The extension cavity 302 is formed inside the work box 1. The electric telescopic rod 303 is fixedly connected to the top surface of the inner wall of the work box 1. The top surface of the sliding plate 304 is fixedly connected to the output end of the electric telescopic rod 303. The extension mechanism 3 also includes two first rotating blocks 305, two extension rods 306, and two second rotating blocks 307. The two first rotating blocks 305 are respectively fixedly connected to the bottom surface of the sliding plate 304. One end of each of the two extension rods 306 is rotatably connected to the surface of the two first rotating blocks 305, and the other end of each of the two second rotating blocks 307 is rotatably connected to the other end of the two extension rods 306. The extension mechanism 3 also includes two extension blocks 308, which are slidably connected to the bottom surface of the inner wall of the work box 1. The opposite ends of the two extension blocks 308 extend through the interior of the work box 1 to the outside, and both sides of the top surface of the extension block 308 are fixedly connected to the bottom surface of the two second rotating blocks 307.

[0022] like Figure 3As shown, both light guiding mechanisms 4 include a guiding box 401, a working cavity 402, an extension slot 403, a battery pack 404, and an illumination lamp 405. The guiding box 401 is fixedly connected to the bottom surface of the extension block 308. The working cavity 402 is formed inside the guiding box 401. The extension slot 403 is formed on one side of the surface of the guiding box 401. The battery pack 404 is slidably connected to the inner wall of the extension slot 403. The battery pack 404 can be pulled out and replaced through the extension slot 403, thereby continuously supplying power to the illumination lamp 405. At the same time, the battery pack 404 is inserted... As the light enters the extension groove 403, there will be a frictional force, which acts as a limiting force and extends into the working cavity 402. The illumination lamp 405 is located on one side of the surface of the guide box 401. The two light guiding mechanisms 4 also include an inclined plate 406 and a reflector 407. The inclined plate 406 is fixedly connected to one side of the surface of the guide box 401, and the reflector 407 is fixedly connected to the bottom surface of the inclined plate 406. The light emitted by the illumination lamp 405 is a linear light, which, through the reflection of the reflector 407, will make a standard straight line appear on the ground.

[0023] like Figure 4 As shown, the rotating structure 5 includes a base 501, a transmission groove 502, a motor 503, and a connecting column 504. The base 501 is located on the bottom surface of the working box 1, the transmission groove 502 is opened on the top surface of the base 501, the motor 503 is fixedly connected to the bottom surface of the inner wall of the transmission groove 502, and the connecting column 504 is rotatably connected to the inner wall of the transmission groove 502.

The two ends of the sliding plate 304 are respectively slidably connected to the inside of the two limiting grooves 7, which can limit the sliding plate 304 to achieve the standard vertical lifting effect.

[0025] The working principle of this utility model is as follows: When the driver arrives at the parking lot and needs to park, the infrared alignment light 2 on the top surface of the work box 1 is used for detection. Then, the electric telescopic rod 303 is used to make a quick adjustment and control the sliding plate 304 at the bottom to slide inside the limiting grooves 7 on both sides. As the sliding plate 304 moves downward, the extension rod 306 first achieves a displacement and rotation effect through the first rotating block 305, and then achieves a lateral displacement effect through the second rotating block 307. Finally, the extension blocks 308 on both sides of the surface of the work box 1 produce opposite extension effects. When the two extension blocks 308 extend to match the width of the car, linear lights can be emitted by the illumination lamp 405 and shone on the reflector 407 on the ground of the inclined plate 406. The reflection will cause the linear lights to shine on the top surface of the ground, and the driver can use the light lines on the ground to assist in parking.
