Description

Technical Field

[0001] This patent belongs to the field of road sign technology, and specifically relates to a traffic variable lane conversion indicator device. Background Art

[0002] Due to the development of society and the increasing number of cars, great pressure has been added to urban roads, often leading to congestion at intersections. In order to make full use of the existing road space, setting up variable lanes and variable lane signs at intersections plays a vital role in evacuating traffic and reducing congestion and accidents.

[0003] However, most of the existing variable lane signs are LED screens, which mainly display patterns composed of luminous LED lights. The LED screen consumes a lot of power when working 24 hours a day. Due to material defects, the brightness of LED lights is easily attenuated after long-term use, and the LED screen has poor indication effect in the later stage. The luminous LED lights work 24 hours a day, but the heat dissipation problem is not easy to solve, resulting in an extremely short service life. Once an LED light is damaged, the LED screen needs to be replaced as a whole for later maintenance, which is difficult to replace and has high maintenance costs. Utility Model Content

[0004] In response to the problems existing in the above-mentioned prior art, this patent provides a traffic variable lane conversion indicator device that can effectively save energy consumption, extend service life and facilitate maintenance.

[0005] To solve the above problems, the technical solution adopted by this patent is:

[0006] A traffic variable lane conversion indication device comprises an indication sign body, on which a variable arrow indication plate is provided; the variable arrow indication plate is connected to a vertical indication plate located below the variable arrow indication plate via a pin shaft; the vertical indication plate is provided with a pin shaft; a steering device is provided on the variable arrow indication plate; and the steering device is electrically connected to a control device.

[0007] The sign body is provided with a track groove, which is one or more than one track groove, and the pin shaft is arranged in the track groove to slide up and down.

[0008] The variable arrow indicator panel and the vertical indicator panel are provided with LED lights; the LED lights are electrically connected to the control device.

[0009] The variable arrow indicator plate and the vertical indicator plate are luminous plates coated with a fluorescent coating.

[0010] The variable arrow indicator plate or the vertical indicator plate or the indicator body is provided with a photosensitive sensor; the photosensitive sensor is electrically connected to the control device.

[0011] The steering device is arranged in front of, behind or inside the sign body.

[0012] The steering device is a steering gear or a servo motor or an electric actuator with a rotation angle of 90 degrees.

[0013] The sign body is provided with a power module, which is a rechargeable battery and can be charged by city electricity or by a solar panel.

[0014] A method for using a traffic variable lane conversion indication device. When indicating a left turn, a steering device drives a variable arrow indication plate to rotate 90 degrees to the left, and the variable arrow indication plate drives a vertical indication plate to slide to the upper right along a track groove through a pin shaft, and the variable arrow indication plate and the vertical indication plate are combined to indicate a left turn lane; when indicating a straight-ahead, the steering device drives the variable arrow indication plate to rotate 90 degrees to the right again, and the variable arrow indication plate drives the vertical indication plate to slide to the lower left along the track groove through a pin shaft, and the variable arrow indication plate and the vertical indication plate are combined to indicate a straight-ahead lane.

[0015] A method for using a traffic variable lane conversion indication device. When the light intensity is strong, the control device controls an LED lamp not to emit light according to a photosensitive sensor signal, and uses the physical state position of a variable arrow indication plate and a vertical indication plate to indicate the lane; when the light intensity is weak, the control device controls the LED lamp to emit light according to the photosensitive sensor signal, and uses the physical state position of the variable arrow indication plate and the vertical indication plate and the emitting LED lamp to form a lane indication.

[0016] Compared with the prior art, the beneficial effects of this patent are:

[0017] 1. This patented device uses a steering device to change the direction of the variable arrow indicator board when the light is strong, and uses the indicator board itself for indication without the need for LED lights; when the light is weak, indication is performed by combining the LED lights on the variable arrow indicator board and the state of the variable arrow indicator board itself.

[0018] 2. The LED light of this patented device only works when the light is weak, which has the effect of saving energy and extending the service life, and is very practical.

[0019] 3. The variable arrow indicator plate and vertical indicator plate of this patented device are split from the indicator body, which is convenient for maintenance and saves maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a further detailed description of this patent in conjunction with the accompanying drawings, but the following examples are only used to more clearly illustrate the technical solution of this patent. Any changes made by ordinary technicians in this field based on the implementation plan are within the scope of protection of this patent.

[0027] like Figure 1 and Figure 2 As shown, the present invention provides a traffic variable lane conversion indicator device, including a sign body 1, a variable arrow indicator plate 2 is provided on the sign body 1, the variable arrow indicator plate 2 and the vertical indicator plate 3 located below the sign body 1 are connected by a pin 10, the variable arrow indicator plate 2 and the vertical indicator plate 3 can be made of aluminum alloy material, circuits are printed on the variable arrow indicator plate 2 and the vertical indicator plate 3, LED lights 7 are also provided on the variable arrow indicator plate 2 and the vertical indicator plate 3, fluorescent coatings are coated on the variable arrow indicator plate 2 and the vertical indicator plate 3, and they are fixed together on the sign body 1. A steering device 5 is provided on the variable arrow indicator plate 2, the steering device 5 is electrically connected to the control device 4, and the control device 4 controls the steering device 5 to rotate according to different time periods and different traffic flows. The steering device 5 can drive the variable arrow indicator plate 2 to rotate left and right. When the variable arrow indicator plate 2 rotates left and right, the variable arrow indicator plate 2 drives the vertical indicator plate 3 to slide up and down along the track groove 9 through the pin 10.

[0028] The steering device 5 can be fixed in front of the sign body 1, or in the back of the sign body 1, or in the interior of the sign body 1. According to the installation situation and aesthetic effect, the steering device 5 is arranged in the interior of the sign body in this example.

[0029] like Figure 3 and Figure 4As shown, it is a rendering of the method of using the device of the present invention. When a left turn lane indication is required, the control device 4 outputs a control signal to control the steering device 5 to turn left 90 degrees, driving the turning of the variable arrow indicator plate 2. The variable arrow indicator plate 2 turns left 90 degrees, and the variable arrow indicator plate 2 drives the vertical indicator plate 3 to slide to the upper right through the pin 10. The variable arrow indicator plate 2 and the vertical indicator plate 3 form a left turn lane indication. When a straight lane indication is required, the control device 4 outputs a control signal to control the steering device 5 to turn right 90 degrees again, driving the variable arrow indicator plate 2 to turn, and the variable arrow indicator plate 2 returns to the starting state. The variable arrow indicator plate 2 drives the vertical indicator plate 3 to slide to the lower left along the track groove 9 through the pin 10, and the variable arrow indicator plate 2 and the vertical indicator plate 3 form a straight lane indication. In the example of the present invention, the sign body 1 and the variable arrow indicator plate 2 and the vertical indicator plate 3 are detachable structures. When they are maintained and replaced later, they can be maintained and replaced separately, which is more convenient, simpler and faster than the prior art that the sign needs to be replaced as a whole when it is damaged, saving maintenance costs and working hours.

[0030] like Figure 5 As shown, it is a circuit principle block diagram of the device of the present invention. The control device 4 is constructed by a C51 single chip microcomputer. The control line of the steering device 5 is connected to the output interface of the controller device 4. The controller device 4 outputs a control signal to control the steering of the steering device 5 as needed. The photosensitive signal of the photosensitive sensor 6 is connected to the input interface of the control device 4. The control line of the LED lamp 7 is connected to the output interface of the control device 4. The control device 4 controls whether the LED lamp 7 is lit or not according to the photosensitive signal. The method of using the device of the present invention is as follows: when the light is strong, the control device 4 controls the LED lamp 7 not to light up, and uses the physical state of the variable arrow indicator board 2 and the vertical indicator board 3 to provide lane indication for the variable lane. When the light is weak, the control device 4 controls the LED lamp 7 to light up. As mentioned above, when the variable arrow indicator board 2 rotates with the steering device 5, due to the light-emitting effect of the LED lamp 7, the present invention adopts the method of combining the physical state with the light-emitting LED lamp 7 electromechanically, and can still provide the lane indication effect. The LED lamp 7 does not light up half of the time every day. The example of the present invention has the effect of saving energy consumption, which greatly improves the practicality of the device of the present invention.

[0031] The steering device 5 is composed of a steering gear or a servo motor or an electric actuator with a rotation angle of 90 degrees, and the control device 4 controls the steering device 5 to achieve a 90-degree left and right turn. For example, taking the steering gear as an example, the control device 4 only needs to output a pulse width modulation signal to control the steering gear to turn left and right within a 90-degree rotation angle range. The controller device 4 is set to output a steering signal at a fixed time period. For example: according to comprehensive judgment, there are many left-turning vehicles during the morning rush hour, and it is necessary to set a left-turn lane indication during the morning rush hour. The control device 4 will output a control signal for a 90-degree left turn to control the steering device 5 to turn. If a straight lane indication is required in other time periods, the control device 4 will output a control signal for a 90-degree right turn to control the steering device 5 to turn.

[0032] Now most intersections have implemented intelligent traffic control. The control device 4 of this patent can also be connected to the intelligent traffic control system, which can adjust the steering control device 5 in real time according to the needs of different time periods and different traffic flows, and provide variable lane direction instructions.

[0033] The power module 8 of the patented device is composed of a rechargeable battery. The power module 8 is configured to be charged by the mains while working, and can also be charged by a solar panel. The power module 8 solves the problem that other indicating devices cannot work during power outages at night.
