Description
Technical Field
[0001] This utility model relates to the field of wayfinding signage technology, and in particular to a smart wayfinding sign for smart cities. Background Technology
[0002] With the continuous advancement and development of the concept of smart cities, information technology is being widely applied to various fields of urban management and services. As an important component of urban public service information systems, wayfinding signage systems are also transforming towards intelligence and informatization.
[0003] However, in existing technologies, most signs on directional signage devices are bolted to the outer wall of the device. Each sign requires multiple bolts, and multiple signs require even more. When the information on the sign needs to be changed, the sign often has to be removed. The large number of bolts involved in disassembly and reassembly is very time-consuming and hinders the efficiency of sign replacement work. Furthermore, some existing directional signs have a fixed height after installation, making them unable to be flexibly adjusted according to actual needs. This can lead to poor directional effectiveness in different scenarios, such as during peak traffic hours when the signs cannot be raised to more prominently guide vehicle and pedestrian traffic. Utility Model Content
[0004] In view of the above-mentioned problems in the existing technology, the main purpose of this utility model is to provide a smart city intelligent directional sign, which solves the problem that most signs on directional sign devices in the existing technology are fixed to the outer wall of the directional sign device with bolts. One sign requires multiple bolts for fixation, and multiple signs require even more bolts. When the information on the sign needs to be changed, the sign often has to be removed. The large number of bolts involved in disassembly and reassembly is very time-consuming and not conducive to improving the work efficiency of staff in changing signs. Some existing directional signs have a fixed height after installation and cannot be flexibly adjusted according to actual needs, which may lead to poor directional effect in different scenarios. For example, during peak traffic hours, the signs cannot be raised to more conspicuously guide the flow of vehicles and pedestrians.
[0005] The technical solution of this utility model is as follows: a smart city intelligent directional sign includes a column and a cap. The column has a first groove inside, and a threaded rod is rotatably connected to the bottom of the inner wall of the first groove. The column has a second groove on each of its four sides, and the second grooves are all connected to the first grooves. The threaded rod is threaded with screw blocks at equal intervals on its outer side, and a directional sign is fixedly connected to the outer side of each screw block. The directional sign extends through the corresponding second groove to the outer side of the column. A housing is fixedly connected to the outer side of the column and below the second groove. A display screen is provided on the outer side of each housing.
[0006] The above technical solutions allow for adjustments to the height of directional signs to adapt to different usage scenarios and needs. For example, during peak traffic hours, the signs can be raised to ensure clear visibility for vehicles and pedestrians in the distance. When not needed, they can be lowered to prevent damage. With urban planning adjustments, the emergence of new landmarks, or the holding of events, directional signs can be quickly replaced to accurately convey the latest directional information. Furthermore, directional signs can be flexibly added based on the busyness of different road sections and the needs of special time periods, improving information transmission efficiency and comprehensively assisting pedestrians and vehicles in smooth passage. The display screen provides intuitive auxiliary directional information, and the two complement each other, greatly enhancing the level of urban wayfinding services.
[0007] In a preferred embodiment, two buckles are fixedly connected to the bottom of the cap around its perimeter. The top of the column, on both sides of the second sliding groove, has slots. The inside of the column, on one side of each slot, has a groove. Two sliding rods are slidably connected to the inner walls of each groove. A locking block is fixedly connected between each pair of sliding rods. The ends of each pair of sliding rods away from the locking blocks extend to the outside of the column and are fixedly connected to a connecting plate. A spring is fixedly connected between the connecting plate and the column, on the outside of each sliding rod. Locking holes are provided on the outer sides of each buckle, and these holes engage with corresponding locking blocks.
[0008] Through the above technical solution, the connection method of this buckle and block makes the installation and removal of the cap more convenient, facilitates the maintenance and repair of the inside of the sign, and at the same time ensures the stability of the cap during normal use and prevents it from falling off accidentally.
[0009] In a preferred embodiment, a rubber block is rotatably connected to the top of the inner wall of the cap, the rubber block is in contact with the threaded rod, and a base is fixedly connected to the bottom of the column.
[0010] Through the above technical solution, the tight contact between the rubber block and the threaded rod creates a stable rotational environment for the threaded rod, greatly improving the accuracy of mechanical transmission. In long-term, frequent raising and lowering of the signpost, it effectively avoids displacement deviation of the threaded block caused by shaking, ensuring that the signpost is accurately positioned and stably stays at the preset height each time it is raised or lowered, resulting in accurate information display.
[0011] In a preferred embodiment, a slot is provided inside the column and below the first sliding groove. A servo motor is fixedly connected inside the slot. The output shaft of the servo motor is fixedly connected to a threaded rod. Heat dissipation holes are provided at equal intervals on the outer side of the column, and all heat dissipation holes communicate with the inside of the slot.
[0012] Through the above technical solution, the servo motor achieves automated control, allowing for precise adjustment of the sign's height and improving operational convenience and accuracy. The heat dissipation holes effectively prevent the servo motor from being damaged by overheating, ensuring the sign's long-term stable operation.
[0013] In a preferred embodiment, the column is made of carbon fiber material and has internal reinforcing ribs.
[0014] Through the above technical solutions, carbon fiber materials make the columns lightweight, facilitating transportation and installation, while their high strength can withstand strong outdoor winds, impacts, and other external forces, reducing maintenance costs due to structural damage and extending the lifespan of the signage. Reinforcing ribs further enhance structural stability.
[0015] In a preferred embodiment, the outer surface of the display screen is provided with an anti-glare coating, which is composed of multiple layers of transparent nanomaterials.
[0016] Through the above technical solution, in strong light environments, such as when the sun is shining directly, the anti-glare coating can keep the directional information on the display screen clearly visible, avoiding situations where pedestrians or drivers cannot see the content of the display screen due to reflection, thus improving the practicality and reliability of the directional signs.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0018] In this invention, the height of the directional sign can be adjusted to adapt to different usage scenarios and needs. For example, during peak traffic hours, the directional sign can be raised so that vehicles and pedestrians in the distance can see it clearly. When not needed, it can be lowered to prevent damage. With urban planning adjustments, the emergence of new landmarks, or the holding of events, the directional sign can be quickly replaced to accurately convey the latest directional information. It can also flexibly add directional signs according to the busyness of different road sections and the needs of special time periods to improve the efficiency of information transmission and comprehensively help pedestrians and vehicles to pass smoothly. The display screen provides people with intuitive auxiliary directional information. The two complement each other and greatly improve the level of urban wayfinding services. This buckle and block connection method makes the installation and removal of the cap more convenient, which facilitates the maintenance and repair of the inside of the sign. At the same time, it can also ensure the stability of the cap during normal use and prevent it from falling off accidentally.
[0019] The tight contact between the rubber block and the threaded rod creates a stable rotational environment for the threaded rod, greatly improving the precision of the mechanical transmission. During frequent raising and lowering of the directional sign, it effectively avoids displacement deviation of the threaded block caused by shaking, ensuring that the directional sign is precisely positioned and stably stopped at the preset height with each raising and lowering, resulting in accurate information display. The servo motor enables automated control, allowing for precise adjustment of the directional sign's height, improving operational convenience and accuracy. The heat dissipation holes effectively prevent the servo motor from being damaged by overheating, ensuring long-term stable operation of the sign. The carbon fiber material makes the column lightweight, facilitating transportation and installation, while its high strength can withstand strong outdoor winds, impacts, and other external forces, reducing maintenance costs due to structural damage and extending the sign's lifespan. Reinforcing ribs further enhance structural stability. In strong light environments, such as direct sunlight, the anti-glare coating ensures that the directional information on the display screen remains clearly visible, preventing pedestrians or drivers from being unable to see the display content due to reflections, thus improving the practicality and reliability of the directional sign.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] Example
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model provides a technical solution: including a column 1 and a cap 7. The inside of the column 1 is provided with a first sliding groove 2. The bottom of the inner wall of the first sliding groove 2 is rotatably connected with a threaded rod 4. The four sides of the column 1 are provided with second sliding grooves 3, and the second sliding grooves 3 are all connected to the first sliding grooves 2. The outer side of the threaded rod 4 is threaded with screw blocks 5 at equal intervals. The outer side of each screw block 5 is fixedly connected with a pointer 6. The pointer 6 extends through the corresponding second sliding groove 3 to the outer side of the column 1. The outer side of the column 1 and below the second sliding groove 3 is fixedly connected with a housing 20. The outer side of the housing 20 is provided with a display screen 21.
[0028] In this embodiment, the entire signboard is mainly structured around a pillar 1 and a cap 7. The first groove 2 inside the pillar 1 provides installation space for the threaded rod 4, which is rotatably connected at the bottom. The second grooves 3 on all four sides of the pillar 1 communicate with the first groove 2, allowing the screw blocks 5, which are threadedly connected to the threaded rod 4, to move up and down along the first groove 2 as the threaded rod 4 rotates. The screw blocks 5 drive the outerly fixed directional sign 6 to slide within the second groove 3, thus allowing the directional sign 6 to extend or retract from the outside of the pillar 1. At the connection point between the directional sign 6 and the screw blocks 5, each screw block 5 has a pre-installed standard interface and fastening device. When the directional sign 6 needs to be replaced, the directional sign 6 with the screw blocks 5 is directly threaded onto the threaded rod 4, following the procedure described above. Meanwhile, the housing 20 on the outside of the pillar 1 is used to house electronic equipment, and the display screen 21 on the outside of the housing 20 is used to display directional information.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, two buckles 15 are fixedly connected to the bottom of the cap 7 around its perimeter. The top of the column 1 and both sides of the second slide groove 3 are provided with slots 9. The inside of the column 1 and one side of the slots 9 are provided with grooves 10. The inner wall of the grooves 10 is slidably connected to two slide rods 11. A locking block 14 is fixedly connected between the two corresponding slide rods 11. The ends of the two corresponding slide rods 11 away from the locking block 14 extend to the outside of the column 1 and are fixedly connected to a connecting plate 12. A spring 13 is fixedly connected between the connecting plate 12 and the column 1 and the outside of the slide rod 11. The outer side of the buckles 15 is provided with locking holes 16, which are used in conjunction with the corresponding locking blocks 14.
[0030] In this embodiment, the buckles 15 around the bottom of the cap 7 are used to connect with the column 1. When the cap 7 is installed on the top of the column 1, the buckles 15 are inserted into the slots 9 at the top of the column 1. At the same time, inside the column 1, the slide bar 11 in the groove 10 can push the locking block 14 into the locking hole 16 of the buckle 15 under the action of the spring 13, thereby fixing the cap 7. When it is necessary to remove the cap 7, by pressing the connecting plate 12, the slide bar 11 drives the locking block 14 out of the locking hole 16, and the cap 7 can be removed.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a rubber block 8 is rotatably connected to the top of the inner wall of the cap 7, and the rubber block 8 is in contact with the threaded rod 4. A base 22 is fixedly connected to the bottom of the column 1.
[0032] In this embodiment, a rubber block 8 is cleverly rotatably connected to the top of the inner wall of the cap 7, and the rubber block 8 tightly abuts against the threaded rod 4. During actual operation, when the servo motor 18 drives the threaded rod 4 to rotate, the rubber block 8, due to its inherent elasticity and friction, will tightly adhere to the outer wall of the threaded rod 4, applying uniform pressure from multiple directions. This flexible contact fills the tiny gap between the threaded rod 4 and the cap 7.
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a slot 17 is provided inside the column 1 and below the first slide groove 2. A servo motor 18 is fixedly connected inside the slot 17. The output shaft of the servo motor 18 is fixedly connected to the threaded rod 4. Heat dissipation holes 19 are provided at equal intervals on the outer side of the column 1. All heat dissipation holes 19 are connected to the inside of the slot 17.
[0034] In this embodiment, the servo motor 18 in the internal slot 17 of the column 1 drives the threaded rod 4 connected to its output shaft to rotate, thereby moving the screw block 5 and the pointer plate 6. The heat dissipation hole 19 on the outside of the column 1 communicates with the slot 17 and is used to dissipate the heat generated by the servo motor 18 when it is working.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, column 1 is made of carbon fiber material and has reinforcing ribs inside.
[0036] In this embodiment, the column 1 is made of carbon fiber material, which has the characteristics of high strength and low weight. The reinforcing ribs inside the column 1 further enhance the overall strength of the column 1 and can withstand greater external forces.
[0037] likeFigure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the outer surface of the display screen 21 is provided with an anti-glare coating, which is composed of multiple layers of transparent nanomaterials.
[0038] In this embodiment, the anti-glare coating on the outer surface of the display screen 21 is composed of multiple layers of transparent nanomaterials. This coating can scatter and refract light, reducing light reflection.
[0039] Working principle:
[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the entire signboard is mainly structured around a pillar 1 and a cap 7. The first groove 2 inside the pillar 1 provides installation space for the threaded rod 4, which is rotatably connected at the bottom. The second grooves 3 on all four sides of the pillar 1 communicate with the first groove 2, allowing the screw blocks 5, which are threadedly connected to the threaded rod 4, to move up and down along the first groove 2 as the threaded rod 4 rotates. The screw blocks 5 drive the outerly fixed directional sign 6 to slide within the second groove 3, thus allowing the directional sign 6 to extend or retract from the outside of the pillar 1. At the connection point between the directional sign 6 and the screw blocks 5, each screw block 5 has a pre-installed standard interface and fastening device. When the directional sign 6 needs to be replaced, the directional sign 6 with the screw blocks 5 is directly threaded onto the threaded rod 4, following the procedure described above. Meanwhile, the housing 20 on the outside of the pillar 1 is used to house electronic equipment, the display screen 21 on the outside of the housing 20 is used to display directional information, and the buckles 15 around the bottom of the cap 7 are used to connect to the pillar 1. When the cap 7 is installed on the top of the column 1, the buckle 15 is inserted into the slot 9 at the top of the column 1. Simultaneously, inside the column 1, the slide rod 11 in the groove 10, under the action of the spring 13, pushes the locking block 14 into the locking hole 16 of the buckle 15, thus securing the cap 7. When it is necessary to remove the cap 7, pressing the connecting plate 12 causes the slide rod 11 to move the locking block 14 out of the locking hole 16, allowing the cap 7 to be removed.
[0041] A rubber block 8 is cleverly rotatably connected to the top of the inner wall of the cap 7. The rubber block 8 tightly abuts against the threaded rod 4. During actual operation, when the servo motor 18 drives the threaded rod 4 to rotate, the rubber block 8, due to its own elasticity and friction, will tightly adhere to the outer wall of the threaded rod 4, applying uniform pressure from multiple directions. This flexible contact fills the tiny gap between the threaded rod 4 and the cap 7. The servo motor 18 in the slot 17 inside the column 1 drives the threaded rod 4 connected to its output shaft to rotate, thereby moving the screw block 5 and the indicator plate 6. The heat dissipation holes 19 on the outside of the column 1 are connected to the slot 17 to dissipate the heat generated by the servo motor 18 during operation. The column 1 is made of carbon fiber material, which has the characteristics of high strength and low weight. The reinforcing ribs inside the column 1 further enhance the overall strength of the column 1, enabling it to withstand greater external forces. The anti-glare coating on the outer surface of the display screen 21 is composed of multiple layers of transparent nanomaterials. This coating can scatter and refract light, reducing light reflection.
[0042] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
