Description

Technical Field

[0001] The utility model relates to the technical field related to traffic signs, and in particular to an intelligent road traffic sign based on tidal traffic flow. Background Art

[0002] Tidal traffic refers to the phenomenon of heavy traffic entering a city in the morning and heavy traffic leaving the city in the evening. Some residents believe that installing tidal variable lanes on relevant roads, allowing these lanes to serve as inbound lanes during the morning rush hour and outbound lanes during the evening rush hour, and reallocating road resources based on demand, could better cope with tidal traffic flows. Tidal lanes are lanes on road sections that can change direction based on traffic flow. Within cities, based on the varying traffic volumes in the morning and evening, one or more lanes with varying direction of travel can be installed on suitable roads.

[0003] Currently, there are two main types of tidal signs. One is an LED sign, which can be powered by re-pulling wires. The LED sign can change the displayed sign, and the driver can intuitively observe and receive the information of passing and not passing. It is then used with solar panels and batteries. At this time, no additional wires are required, which can reduce the installation workload of the sign. Because LED signs require continuous power supply, when encountering continuous rainy days, the battery power cannot be replenished in time, and power outages will occur; the other is to use a metal blue and white sign, and the passing time is marked at the bottom of the blue and white sign. However, the sign is a passing sign, and the driver is prone to not driving into the tidal lane within the passing time. Therefore, it is necessary to design an intelligent road traffic sign based on tidal traffic flow. Utility Model Content

[0004] In view of the above technical problems, the purpose of the present utility model is to overcome the problem in the prior art that the driver always sees the blue and white signboard as a traffic sign, which makes it easy for the driver to drive into the tidal lane during the stationary traffic time.

[0005] In order to achieve the above-mentioned object, the utility model provides an intelligent road traffic sign based on tidal traffic flow, comprising: a vertical hollow column, a vertical sign body, a connecting frame fixedly connected to the top of the column, a hollow mounting arm fixedly connected to the column and located below the connecting frame, a vertical drive shaft assembled inside the column, a motor with an output shaft connected to the drive shaft, and a U-shaped clamp connected to the column in a horizontal sliding manner and capable of being sleeved on the side of the sign body;

[0006] The top center of the sign body is axially connected to the connecting frame through a vertical first rotating shaft, and the bottom center of the sign body is fixedly connected to a second rotating shaft which is coaxial with the first rotating shaft and axially connected to the mounting arm. The drive shaft is connected to the lower end of the second rotating shaft through a first transmission mechanism to drive the second rotating shaft to rotate intermittently. The drive shaft is connected to the U-shaped clamp through a second transmission mechanism to drive the U-shaped clamp to slide back and forth. When the second rotating shaft rotates, the U-shaped clamp is in a position away from the sign body.

[0007] Preferably, the second transmission mechanism includes a mounting bracket fixedly mounted inside the column, a first guide sleeve fixedly mounted on the mounting bracket, a second guide sleeve fixedly mounted on the inner wall of the column close to the body of the sign, a horizontal sliding arm sliding through the first guide sleeve and the second guide sleeve and fixedly connected to the U-shaped clamp, an elastic member for pushing the sliding arm to slide close to the body of the sign, a connecting arm fixedly connected to the sliding arm and a turntable fixedly mounted on the drive shaft coaxially, an arc-shaped protrusion portion coaxially arranged protruding from the outer wall of the turntable, and the turntable is in sliding contact with one side of the connecting plate close to the U-shaped clamp.

[0008] Preferably, the fixing sleeve on the sliding arm is provided with a limiting ring located between the first guide sleeve and the second guide sleeve, and the elastic member is a spring with two ends respectively in contact with the limiting ring and the first guide sleeve.

[0009] Preferably, the lower end of the second rotating shaft is inserted downward into the interior of the mounting arm, and the first transmission mechanism includes a horizontal connecting shaft installed inside the mounting arm through a plurality of shaft seats and an intermittent transmission component assembled on the end of the connecting shaft close to the drive shaft and connected to the drive shaft, and the end of the connecting shaft away from the drive shaft is connected to the second rotating shaft through a pair of bevel teeth.

[0010] Preferably, the intermittent transmission component comprises a first connecting disc coaxially fixedly sleeved on one end of the connecting shaft close to the driving shaft and a second connecting disc coaxially fixedly sleeved on the driving shaft;

[0011] A second annular flange is coaxially provided on the outer wall of the second connecting disk, and a pair of superior arc-shaped ridges arranged at intervals along the axial direction are coaxially protruded on the outer wall of the second annular flange, and one end of the superior arc-shaped ridge located above is connected to one end of the superior arc-shaped ridge located below through an inclined guide strip. A first annular flange is coaxially protruded on the end of the first connecting disk close to the drive shaft, and a plurality of slots are recessed on one side of the first annular flange close to the drive shaft and are evenly distributed in the circumferential direction and matching the superior arc-shaped ridges.

[0012] Preferably, a mounting plate with mounting holes formed therein is provided at the bottom of the column.

[0013] Preferably, an openable and closable cover is provided on one side of the column.

[0014] According to the above technical solution, the utility model provides an intelligent road traffic sign based on tidal traffic flow, which has the following beneficial effects when used: first, the sign body can be rotated so that the no-entry sign on the sign body faces the driver's perspective, preventing the driver from mistakenly entering the tidal lane. After the sign body is rotated 180 degrees, the U-shaped clip can be stuck on the side of the sign body, providing support for the sign body and improving wind resistance;

[0015] Secondly, the motor only needs to be started twice a day, consuming less power. When used with solar panels and batteries, there is no need for traction wires, and the sign can still work normally even under continuous cloudy days.

[0016] Third, the sign body is still made of metal, which can improve durability.

[0027] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0028] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0029] like Figure 1-6 As shown, an intelligent road traffic sign based on tidal traffic flow includes: a vertical hollow column 1, a vertical sign body 2, a connecting frame 3 fixedly connected to the top of the column 1, a hollow mounting arm 4 fixedly connected to the column 1 and located below the connecting frame 3, a vertical drive shaft 5 assembled inside the column 1, a motor 6 with an output shaft connected to the drive shaft 5, and a U-shaped clamp 7 horizontally slidably connected to the column 1 and capable of being sleeved on the side of the sign body 2;

[0030] The top center of the sign body 2 is axially connected to the connecting frame 3 through a vertical first rotating shaft 8, and the bottom center of the sign body 2 is fixedly connected to a second rotating shaft 9 which is coaxial with the first rotating shaft 8 and axially connected to the mounting arm 4. The drive shaft 5 is connected to the lower end of the second rotating shaft 9 through a first transmission mechanism to drive the second rotating shaft 9 to rotate intermittently. The drive shaft 5 is connected to the U-shaped clamp 7 through a second transmission mechanism to drive the U-shaped clamp 7 to slide back and forth. When the second rotating shaft 9 rotates, the U-shaped clamp 7 is in a position away from the sign body 2.

[0031] Both sides of the sign body 2 are provided with a pass and a no pass sign respectively. When the sign body 2 is rotated 180 degrees, the sign on the other side can be placed in front of the driver's line of sight; the angle value of each rotation of the second rotating shaft 9 is a factor of 180, so after the second rotating shaft 9 rotates several times, the sign body 2 can be rotated exactly 180 degrees.

[0032] The motor 6 drives the first transmission mechanism and the second transmission mechanism to start through the drive shaft 5. Before the first transmission mechanism drives the second rotating shaft 9 to rotate, the second transmission mechanism will drive the U-shaped clamp 7 to slide away from the sign body 2, so that the U-shaped clamp 7 is separated from the sign body 2. At this time, the drive shaft 5 continues to rotate, and the U-shaped clamp 7 will be at a position away from the sign body 2 and remain stationary. The drive shaft 5 continues to rotate and will drive the second rotating shaft 9 to rotate through the first transmission mechanism. When the second rotating shaft 9 stops after rotating, the drive shaft 5 continues to rotate and will drive the U-shaped clamp 7 to move closer to the sign body 2 through the second transmission mechanism, because the second rotating shaft 9 needs to rotate multiple times to drive the sign body 2 to rotate 180 degrees.

[0033] After the second rotating shaft 9 rotates for the last time, the driving shaft 5 continues to rotate and drives the U-shaped clamp 7 to move closer to the sign body 2 through the second transmission mechanism. At this time, the U-shaped clamp 7 will be mounted on the side of the sign body 2. When the wind blows the sign body 2, the U-shaped clamp 7 can provide support force for the sign body 2 to improve the wind resistance of the sign.

[0034] A timer can be set inside the column 1 to control the start time of the motor 6; it can also be connected to the control terminal through a limited transmission module or a wireless transmission module, and the start time of the motor 6 can be set through the control terminal, or the start of the motor 6 can be manually intervened through the control terminal.

[0035] It can be used in conjunction with solar panels and batteries, so the motor 6 only needs to be started twice a day, so the daily power consumption of the entire sign is low, and the battery power can support the continuous use of the motor 6 for many days. Even in continuous rainy days, the motor 6 can still start normally.

[0036] The second transmission mechanism includes a mounting frame 10 fixedly mounted inside the column 1, a first guide sleeve 11 fixedly mounted on the mounting frame 10, a second guide sleeve 12 fixedly mounted on the inner wall of the column 1 near the sign body 2, a horizontal sliding arm 13 sliding through the first guide sleeve 11 and the second guide sleeve 12 and fixedly connected to the U-shaped clamp 7, an elastic member 14 for pushing the sliding arm 13 to slide close to the sign body 2, a connecting arm 15 fixedly connected to the sliding arm 13 and a turntable 16 coaxially fixedly sleeved on the drive shaft 5, an outer wall of the turntable 16 protruding with an arc-shaped protrusion portion 17 coaxially arranged, and the turntable 16 is in sliding contact with one side of the connecting plate near the U-shaped clamp 7.

[0037] When the driving shaft 5 rotates, it drives the turntable 16 to rotate. When the arc-shaped protrusion portion 17 contacts the connecting arm 15, it pushes the connecting arm 15 to move away from the identification plate body 2, thereby driving the U-shaped clamping member 7 to move away from the identification plate body 2 through the sliding arm 13; the driving shaft 5 continues to rotate, and at this time the arc-shaped protrusion portion 17 is always in contact with the connecting arm 15, and the U-shaped clamping member 7 is vertically located at a position away from the identification plate body 2 and remains motionless. During the process of the arc-shaped protrusion portion 17 contacting the connecting arm 15, the second rotating shaft 9 completes its rotation; the driving shaft 5 continues to rotate, driving the arc-shaped protrusion portion 17 to separate from the connecting arm 15, the elastic member 14 will push the sliding arm 13 to move close to the identification plate body 2, thereby driving the connecting arm 15 to contact the outer wall of the turntable 16. If the identification plate body 2 has rotated 180 degrees at this time, the U-shaped clamping member 7 can be sleeved on the side of the identification plate body 2.

[0038] The fixed sleeve on the sliding arm 13 is provided with a limiting ring 18 located between the first guide sleeve 11 and the second guide sleeve 12 , and the elastic member 14 is a spring with two ends respectively in contact with the limiting ring 18 and the first guide sleeve 11 .

[0039] The lower end of the second rotating shaft 9 is inserted downward into the interior of the mounting arm 4. The first transmission mechanism includes a horizontal connecting shaft 19 installed inside the mounting arm 4 through a plurality of shaft seats and an intermittent transmission component assembled on the end of the connecting shaft 19 close to the drive shaft 5 and connected to the drive shaft 5. The end of the connecting shaft 19 away from the drive shaft 5 is connected to the second rotating shaft 9 through a pair of bevel teeth.

[0040] The driving shaft 5 rotates continuously, drives the connecting shaft 19 to rotate intermittently through the intermittent transmission component, and drives the second rotating shaft 9 to rotate intermittently through a pair of bevel gears.

[0041] The intermittent transmission component includes a first connecting plate 20 coaxially fixedly sleeved on the end of the connecting shaft 19 close to the driving shaft 5 and a second connecting plate 21 coaxially fixedly sleeved on the driving shaft 5;

[0042] A second annular flange 22 is coaxially provided on the outer wall of the second connecting disk 21, and a pair of superior arc-shaped ridges 23 arranged at intervals along the axial direction are coaxially protruded on the outer wall of the second annular flange 22. One end of the superior arc-shaped ridge 23 located above is connected to one end of the superior arc-shaped ridge 23 located below through an inclined guide strip 24. A first annular flange 25 is coaxially protruded at the end of the first connecting disk 20 close to the drive shaft 5. A plurality of slots 26 are recessed on the side of the first annular flange 25 close to the drive shaft 5 and are evenly distributed in the circumferential direction and matching the superior arc-shaped ridges 23.

[0043] When a pair of superior arc-shaped ridges 23 are respectively inserted into the corresponding slots 26, the driving shaft 5 drives the second connecting disk 21 to rotate when it rotates, and the second connecting disk 21 drives the superior arc-shaped ridges 23 to slide in the corresponding slots 26. At this time, the first connecting disk 20 does not rotate; when the guide bar 24 is inserted into the slot, because the guide bar 24 is in an inclined state, the guide bar 24 can drive the first connecting disk 20 to rotate when it slides in the slot 26, thereby driving the connecting shaft 19 to rotate. When the guide bar 24 slides out of the slot, it will drive the superior arc-shaped ridges 23 to insert into the corresponding slot. Therefore, when the driving shaft 5 continues to rotate, it will drive the connecting shaft 19 to rotate intermittently, thereby driving the sign body 2 to rotate intermittently around the axis of the second rotating shaft 9.

[0044] The bottom of the column 1 is provided with a mounting plate 27 with mounting holes formed therein.

[0045] An openable cover plate 28 is provided on one side of the column 1 to facilitate subsequent maintenance and repair of the internal parts of the column 1 .

[0046] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0048] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
