Description

Technical Field

[0001] The present invention relates to the technical field of indicating parking space vacancies, and in particular to a traffic control sign for intelligent parking. Background Art

[0002] With the increase in the number of private cars, the following problems have emerged in ground parking lots in scenic spots, large markets, etc.: Although the electronic sign at the entrance of the parking lot shows that there are empty parking spaces, it is difficult for drivers to find parking spaces quickly due to obstruction by other vehicles, resulting in constant searching in the parking lot, causing traffic congestion inside the parking lot and on the roads at the entrance to the parking lot.

[0003] Chinese invention patent publication number CN112863239B discloses a novel ground parking guidance device, comprising a robotic arm 16, a signboard 18, and a rocker 13. After a vehicle enters a parking space, it presses one end of the rocker 13 downward, and the downward end of the rocker 13 indirectly drives the robotic arm 16 to extend upward, thereby extending the signboard 18 out of the shielding box 21. After the vehicle drives out of the parking space, the rocker 13 is reset, the robotic arm 16 retracts, and the signboard 18 descends into the shielding box 21.

[0004] See Figure 1 , the above-mentioned guiding device is installed in the adjacent parking spaces A and B. When the parking space A is parked, the sign 18 of the parking space A rises. The driver can see the sign 18 when he is in the C1 or C2 position, and there is a phenomenon of misidentifying the parking space A as vacant; refer to Figure 1 In the parking route, the driver first goes to parking space A which was incorrectly identified, then finds that parking space B is an empty space, and then drives to parking space B. Summary of the Invention

[0005] The present invention provides a traffic control sign for intelligent parking, and aims to solve the technical problem of how to improve the clarity of parking lot signboards in indicating vacant spaces.

[0006] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0007] A traffic control sign for intelligent parking, a riser, which is fixed vertically at the junction of the front and rear parking spaces;

[0008] The cantilever beam outer tube is arranged horizontally, one end of the cantilever beam outer tube is fixed to the vertical pipe, and the other end of the cantilever beam outer tube is the sign outlet;

[0009] An inner tube rotatably disposed inside the outer tube of the suspension beam;

[0010] A fan-shaped sign that can be opened and closed and has an "arrow" image on both the front and back;

[0011] The arm is extended and connected to the linear drive component and the fan-shaped sign. The linear drive component controls the fan-shaped sign to enter and exit the sign outlet and to open and close.

[0012] A blocking buffer is also provided, which is provided at the portion of the moving part that leaks out of the inner tube; when the fan-shaped indicator moves outward, the sliding shaft can squeeze and pass over the blocking buffer;

[0013] The stepper motor is fixedly installed inside the outer tube of the cantilever beam, and the rotating shaft of the stepper motor is fixed to the inner tube; the stepper motor is used to drive the inner tube and the fan-shaped sign to rotate synchronously;

[0014] Infrared sensor, which is installed in the parking space, is used to identify whether there is a vehicle in the parking space to which it belongs;

[0015] The controller is used to receive signals from the infrared sensor; the controller is electrically connected to the linear drive component and the stepper motor; when both the front and rear parking spaces are vacant, the controller controls the linear drive component and the stepper motor to extend the fan-type sign out of the sign exit and the arrow of the fan-type sign points upward; when only one of the front and rear parking spaces is vacant, the controller controls the arrow of the fan-type sign to point to the empty parking space; when neither the front nor the rear parking space is vacant, the controller controls the linear drive component and the stepper motor to close the folding fan and hide it in the inner tube.

[0016] Furthermore, the fan-type sign includes a folding fan, a movable ring, and a fan rib tail arm; "arrow" images are provided on the front and back of the folding fan; the rotating shaft of the folding fan itself is fixed to the inner wall of the movable ring through a connecting component; two relative sliding shafts are fixed on the outer wall of the movable ring; the guide member is provided with a guiding movable groove, and the two guide members are fixed to the inner wall of the inner tube; the two sliding shafts are respectively slidably provided in different movable grooves; there are two fan rib tail arms in total, and each of the two outer fan ribs of the folding fan is fixed with a fan rib tail arm.

[0017] Furthermore, the linear drive component is fixed to the inner wall of the inner tube, and the moving component of the linear drive component and the fan-bone tail arm are rotationally connected by the primary rotating shaft and the secondary rotating shaft respectively.

[0018] Furthermore, there are two spreading arms, and pins are provided at both ends of the primary rotating shaft and the two secondary rotating shafts in their radial directions. The pins of the secondary rotating shaft and the pins of the primary rotating shaft pass through both ends of the spreading arms;

[0019] Among them, the moving trough partially extends out of the sign exit;

[0020] The blocking buffer is arranged at the part where the moving part leaks out of the inner tube. When the fan-type indicator sign moves outward, the sliding shaft can squeeze and pass over the blocking buffer. When the moving part of the linear drive part moves into the inner tube in the initial stage, the blocking buffer blocks the sliding shaft, causing the sliding shaft to rotate and the fan-type indicator sign is in a horizontal state. Then the moving part continues to move into the inner tube, stretching out its arms to pull the two fan bone tail arms closer to each other, and then the fan is folded and closed. After that, the sliding shaft can squeeze and pass over the blocking buffer, and then the folding fan is hidden in the inner tube.

[0021] Furthermore, specifically, the inner rings of at least two bearings are fixedly sleeved on the outer wall of the inner tube, and the outer rings of the bearings are fixedly connected to the inner wall of the outer tube of the cantilever beam.

[0022] Furthermore, specifically, a limiting groove is provided at one end of the movable groove on the outside of the sign exit; the blocking buffer is located in the limiting groove, and one end of the blocking buffer is rotatably connected to the guide member; the other end of the blocking buffer is fixed to the guide member by a spring, and the spring is in a stretched state; a portion of the blocking buffer is located in the movable groove.

[0023] Furthermore, the limiting member is fixedly connected to the movable ring, and the limiting member is located at the lower side of the guide member; when the fan-shaped indicator sign is located in the inner tube, the limiting member contacts the lower side of the guide member.

[0024] Furthermore, when the fan-shaped indicator is located in the inner tube, the open arms and the limiter are completely located on the same side of the guide member; this can stably maintain the rotation direction of the sliding shaft of the folding fan.

[0025] The beneficial effects of the present invention are:

[0026] 1. Improve the clarity of parking lot signs indicating vacant spaces.

[0027] The cantilever beam outer tube is located above the intersection of the front and rear parking spaces, and the fan-shaped sign can be hidden inside the cantilever beam outer tube to indicate that there are no vacant spaces. When the fan-shaped sign extends out of the cantilever beam outer tube, the arrow pointing to the front or rear parking space indicates that only one is vacant, while the arrow pointing upward indicates that both the front and rear parking spaces are vacant, thus improving the clarity of the parking lot sign's indication of vacant spaces. This can intelligently display and indicate parking lot vacancy information.

[0028] Furthermore, the invented sign can intelligently adjust the direction of its arrow based on the availability of parking spaces in front and behind it, clearly indicating the location of vacant spaces. This functional innovation effectively solves the problems of misidentification and unclear information that can occur with traditional parking signage.

[0029] 2. Improve the visibility of information indicated by fan-shaped signs.

[0030] The fan-type sign can be extended out of the outer tube of the cantilever when needed, which improves the visibility of the sign and enables the driver to clearly see the instruction information from a distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The specific embodiments of the present invention are further described below with reference to the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0047] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[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 with reference to 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 intersection of the front and rear parking spaces, and the fan-shaped sign 700 can be hidden in the cantilever beam outer tube 200 to indicate that there is no vacant space; when the fan-shaped sign 700 extends out of the cantilever beam outer tube 200, the front or rear parking space pointed to by the arrow of the fan-shaped sign 700 is 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 indicating vacant spaces.

[0050] Example 1

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

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

[0053] The cantilever beam outer tube 200 is arranged horizontally, 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 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 outer tube 200. The bearings are not necessary components for the inner tube 500 and the cantilever outer tube 200 to rotate; however, the participation of the bearings can make the inner tube 500 rotate more smoothly inside the cantilever outer tube 200.

[0055] See Figure 4 、 Figure 5 The fan-shaped indicator 700 includes a folding fan 710, a movable ring 720, and a fan tail arm 730; an "arrow" image is provided on both the front and back sides of the folding fan 710; the rotating shaft of the folding fan 710 is fixed to the inner wall of the movable ring 720 through a connecting component 722; two opposite sliding shafts 721 are fixed on the outer wall of the movable ring 720; Figure 3 、 Figure 6The guide member 510 is provided with a guiding movable 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 movable 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 in total, 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 provided on both 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 pins are provided at both ends of the primary rotating shaft 611 and the two secondary rotating shafts 731 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 to the primary rotating shaft 611 and the secondary rotating shaft 731 through the pins.

[0058] See Figure 3 、 6 、 Figure 7 , wherein the movable groove 512 partially extends out of the sign outlet 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 movable groove 512 outside the sign outlet 201, the movable 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 outlet 201. At this time, the sliding shaft 721 of the fan-type sign 700 rotates at the outer end of the movable groove 512. At the same time, since the movable component 610 gradually approaches the fan-bone tail arm 730, the two spreading arms 800 are forced to spread the two fan-bone tail arms 730, and then the folding fan 710 is spread open, and the arrow image on it can be seen by the driver. The spreading 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 outlet 201 and open and close.

[0059] In addition, a blocking buffer 900 is provided. This blocking buffer 900 is positioned at the portion of the moving member that leaks out of the inner tube 500. As the fan-shaped sign 700 moves outward, the sliding shaft 721 can squeeze and pass over the blocking buffer 900. Specifically, the moving groove 512 is provided with a limiting groove 513 at one end outside the sign outlet 201. The blocking buffer 900 is positioned within 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 secured to the guide member 510 via a spring 910, which is in a stretched state. The blocking buffer 900 is partially positioned within the moving groove 512. When the moving part 610 of the linear drive part moves into the inner tube 500 in the initial stage, the blocking buffer 900 blocks the sliding shaft 721, causing the sliding shaft 721 to rotate and the fan-shaped indicator 700 to be in a horizontal state, and then the moving part 610 continues to move into the inner tube 500, stretching out 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, and then the folding fan 710 is hidden in the inner tube 500.

[0060] The stepper motor 400 is fixedly installed inside the cantilever 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 indicator 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 configured to receive signals from the infrared sensor 100 and is electrically connected to the linear drive component and the stepper motor 400. When both the front and rear parking spaces are vacant, the controller controls the linear drive component and the stepper motor 400 to extend the fan-shaped sign 700 from the sign exit 201, with the arrow on the fan-shaped sign 700 pointing upward. When only one of the front and rear parking spaces is vacant, the controller controls the arrow on the fan-shaped sign 700 to point toward the vacant space. When neither the front or rear parking space is vacant, the controller controls the linear drive component and the stepper motor 400 to close the folding fan 710 and conceal it within the inner tube 500.

[0063] In summary, the cantilever 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 outer tube 200 to indicate that there is no vacant space. When the fan-type sign 700 extends out of the cantilever 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.

[0065] Example 2

[0066] For further information, see Figure 8 The limiting member 723 is fixedly connected to the movable ring 720 , and the limiting member 723 is located on the lower side of the guide member 510 ; when the fan-shaped indicator sign 700 is located in the inner tube 500 , the limiting 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 spreading arms 800 and the limiting member 723 are completely located on the same side of the guide member 510 ; this can stably maintain the rotation direction of the sliding shaft 721 of the folding fan 710 .

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
