[0048] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0049] participate Figure 1 The invention concept is as follows: the cantilever beam outer tube 200 is located above the junction of the front and rear parking spaces, and the fan-type sign 700 can be hidden in the cantilever beam outer tube 200 to indicate a no-vacancy state; when the fan-type sign 700 extends out of the cantilever beam outer tube 200, the arrow of the fan-type sign 700 points to a single empty front or rear parking space, and the arrow pointing upwards indicates that both the front and rear parking spaces are empty, thereby improving the clarity of the parking lot sign indicating empty spaces.

[0050] Embodiment 1

[0051] like Figures 1 to 7 As shown, a traffic control sign for intelligent parking,

[0052] The standpipe 300 is vertically fixedly arranged at the junction of the front and rear parking spaces.

[0053] The cantilever beam outer tube 200 is disposed transversely, one end of the cantilever beam outer tube 200 is fixed to the vertical tube 300 , and the other end of the cantilever beam outer tube 200 is a signboard outlet 201 .

[0054] The inner tube 500 can be rotatably arranged inside the cantilever beam outer tube 200; specifically, the inner rings of at least two bearings 210 are fixedly sleeved on the outer wall of the inner tube 500, and the outer rings of the bearings 210 are fixedly connected to the inner wall of the cantilever beam outer tube 200. The bearings are not necessary components for the inner tube 500 and the cantilever beam outer tube 200 to rotate; however, the participation of the bearings can make the inner tube 500 rotate more smoothly inside the cantilever beam outer tube 200.

[0055] See also Figure 4 , Figure 5 The fan-type indicator 700 includes a folding fan 710, a moving ring 720, and a fan-bone tail arm 730; the front and back sides of the folding fan 710 are both provided with "arrow" images; the rotating shaft of the folding fan 710 itself is fixed to the inner wall of the moving ring 720 through a connecting component 722; the outer wall of the moving ring 720 is fixedly provided with two opposite sliding shafts 721; refer to Figure 3 , Figure 6, the guide member 510 is provided with a guiding moving groove 512, and the two guide members 510 are fixed to the inner wall of the inner tube 500; the two sliding shafts 721 are respectively slidably set in different moving grooves 512, that is, the fan-type indicator 700 is slidably set with the inner tube 500. There are two fan-bone tail arms 730, and the two outer fan bones of the folding fan 710 are each fixed with a fan-bone tail arm 730. The approach / distance of the two fan-bone tail arms 730 drives the two outer fan bones of the folding fan 710 to rotate, so that the folding fan 710 can be closed or unfolded. The fan-type indicator 700 can be unfolded and closed, and "arrow" images are set on the front and back sides.

[0056] The linear drive component is fixed to the inner wall of the inner tube 500, and the moving component 610 and the fan-bone tail arm 730 of the linear drive component are rotationally connected by the primary rotating shaft 611 and the secondary rotating shaft 731 respectively.

[0057] There are two spreading arms 800 in total, and both ends of the primary rotating shaft 611 and the two secondary rotating shafts 731 are provided with pins in their radial directions. The pins of the secondary rotating shaft 731 and the pins of the primary rotating shaft 611 pass through both ends of the spreading arm 800; that is, the spreading arm 800 is rotatably connected with the primary rotating shaft 611 and the secondary rotating shaft 731 through the pins.

[0058] See also Figure 3 , 6 , Figure 7 , wherein the moving groove 512 partially extends out of the sign exit 201, and the linear drive component can drive the fan-type sign 700 to reciprocate linearly in the inner tube 500. When the sliding shaft 721 of the fan-type sign 700 slides to the end of the moving groove 512 outside the sign exit 201, the moving component 610 of the linear drive component continues to push the fan-bone tail arm 730 of the fan-type sign 700 toward the sign exit 201. At this time, the sliding shaft 721 of the fan-type sign 700 rotates at the outer end of the moving groove 512. At the same time, since the moving component 610 gradually approaches the fan-bone tail arm 730, the two opening arms 800 are forced to open the two fan-bone tail arms 730, and then the folding fan 710 is opened, and the arrow image on it can be seen by the driver. The opening arm 800 is rotatably connected between the linear drive component and the fan-type sign 700, and the linear drive component controls the fan-type sign 700 to enter and exit the sign exit 201 and open and close.

[0059] In addition, a blocking buffer 900 is also provided, and the blocking buffer 900 is provided at the portion of the moving member 511 that leaks out of the inner tube 500, and the sliding shaft 721 can squeeze and pass over the blocking buffer 900 during the outward movement of the fan-type indicator 700. Specifically, the moving groove 512 is provided with a limiting groove 513 at one end outside the indicator outlet 201; the blocking buffer 900 is located in the limiting groove 513, and one end of the blocking buffer 900 is rotatably connected to the guide member 510; the other end of the blocking buffer 900 is fixed to the guide member 510 by a spring 910, and the spring 910 is in a stretched state; and a portion of the blocking buffer 900 is located in the moving groove 512. When the moving part 610 of the linear drive part moves into the vertical tube 300 in the initial stage, the blocking buffer 900 blocks the sliding shaft 721, causing the sliding shaft 721 to rotate and the fan-type sign 700 is in a horizontal state, and then the moving part 610 continues to move into the vertical tube 300, stretching the arms 800 to pull the two fan-bone tail arms 730 closer to each other, thereby closing the folding fan 710, and then the sliding shaft 721 can squeeze and pass over the blocking buffer 900, so that the folding fan 710 is hidden in the inner tube 500.

[0060] The stepper motor 400 is fixedly installed inside the cantilever beam outer tube 200, and the rotating shaft of the stepper motor 400 is fixed to the inner tube 500; the stepper motor 400 is used to drive the inner tube 500 and the fan-shaped sign 700 to rotate synchronously;

[0061] The infrared sensor 100 is installed in the parking space to identify whether there is a vehicle in the parking space to which it belongs;

[0062] The controller is used to receive the signal of the infrared sensor 100; the controller is electrically connected to the linear drive component and the stepper motor 400. When both the front and rear parking spaces are empty, the controller controls the linear drive component and the stepper motor 400 to make the fan-shaped indicator 700 extend out of the indicator outlet 201 and the arrow of the fan-shaped indicator 700 points upward; when only one of the front and rear parking spaces is empty, the controller controls the arrow of the fan-shaped indicator 700 to point to the empty parking space; when the front and rear parking spaces are not empty, the controller controls the linear drive component and the stepper motor 400 to make the folding fan 710 close and hide in the inner tube 500.

[0063] In summary, the cantilever beam outer tube 200 is located above the junction of the front and rear parking spaces, and the fan-type sign 700 can be hidden in the cantilever beam outer tube 200 to indicate that there is no vacant space. When the fan-type sign 700 extends out of the cantilever beam outer tube 200, the arrow of the fan-type sign 700 points to the front or rear parking space as a single vacant space, and the arrow pointing upwards indicates that both the front and rear parking spaces are vacant, thereby improving the clarity of the parking lot sign in indicating vacant spaces.

[0064] Furthermore, the spreading arm 800 is provided with an arched portion; when the folding fan 710 of the fan-type sign 700 is flipped to a vertical state, the arched portion of the spreading arm 800 can avoid interference with the fan bone tail arm 730.

[0066] For further information, see Figure 8 The limit member 723 is fixedly connected to the movable ring 720 , and the limit member 723 is located at the lower side of the guide member 510 ; when the fan-type indicator sign 700 is located in the inner tube 500 , the limit member 723 contacts the lower side of the guide member 510 .

[0067] Furthermore, when the fan-shaped indicator sign 700 is located in the inner tube 500 , the open arms 800 and the stopper 723 are completely located on the same side of the guide member 510 ; thus, the rotation direction of the sliding shaft 721 of the folding fan 710 can be stably maintained.
