Description

Technical Field

[0001] The utility model belongs to the technical field of road signs, and in particular relates to a variable lane signal indicating 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 later indication effect of the LED screen is not good. 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 view of the problems existing in the above-mentioned prior art, the utility model provides a variable lane signal indicating device which can effectively save energy consumption, extend service life and facilitate maintenance.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] The variable lane signal indicating device comprises a sign body, wherein the sign body is provided with a variable linear plate and a fixed indicating plate, the variable linear plate is combined with the fixed indicating plate located below the sign body, a steering device is provided behind one end of the variable linear plate close to the fixed indicating plate, the steering device is electrically connected to a control device, and the control device controls the steering of the variable linear plate according to different time periods or different traffic flows, the variable linear plate turns left 90 degrees and forms a left turn lane indication with the fixed indicating plate, and the variable linear plate in its initial state forms a straight lane indication with the fixed indicating plate.

[0007] The variable linear plate and the fixed indicator plate are coated with fluorescent coatings, and the variable linear plate and the fixed indicator plate are luminous plates coated with fluorescent coatings. The variable linear plate and the fixed indicator plate are also provided with printed circuits. The surfaces of the variable linear plate and the fixed indicator plate are luminous plates provided with LED lights. The control device controls whether the LED lights emit light according to the change of the light intensity signal of the photosensitive sensor. When the light is strong, the physical state of the linear plate is changed by the steering device to indicate the variable lane. When the light is weak, the LED lights are controlled to emit light. The variable lane indication is performed by combining the physical state of the variable linear plate with the light emission of the LED lights by the steering device. The variable lane indication device performs the steering indication of the variable lane according to the traffic volume in different time periods, realizing the effects of energy saving, extended service life and convenient maintenance of the variable lane conversion indication device.

[0008] The steering device is composed of a steering gear or a servo motor or an electric actuator with a 90-degree rotation angle. The control device controls the steering device to rotate left and right according to different time periods or different traffic flows to change the physical position of the variable linear plate.

[0009] The steering device can be arranged in front of, behind or inside the sign body according to different requirements of installation mode and aesthetic effect.

[0010] The control device is constructed based on a c51 single chip microcomputer. The control device outputs a control signal to control the steering device to rotate left and right, changing the physical state of the variable linear plate. The control device can also control whether the LED lamp emits light according to the light-sensitive sensor signal.

[0011] The power supply module of the further improved variable lane conversion indicator device of the utility model is a rechargeable battery, and the rechargeable battery can be charged by the mains or by a solar panel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses a steering device to change the direction of the variable linear plate when the light is strong, and uses the linear plate itself for indication without the need for LED lighting; when the light is weak, indication is performed by combining the lighting of the LED lamp provided on the variable linear plate with the state of the variable linear plate itself.

[0014] 2. The LED lamp of the utility model works only when the light is weak, which has the effect of saving energy consumption and extending the service life, and also solves the problem of convenient maintenance of the sign body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings, but the following examples are only used to more clearly illustrate the technical solution of the utility model, and changes made by ordinary technicians in this field based on the implementation scheme are all within the protection scope of the utility model.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a variable lane signal indicating device, including a signboard body 1, a control device 4, a variable linear plate 2 is provided on the signboard body 1, the variable linear plate 2 and the fixed indicating plate 3 can be made of aluminum alloy material, circuits are printed on the variable linear plate 2 and the fixed indicating plate 3, LED lights 7 are also provided on the variable linear plate 2 and the fixed indicating plate 3, fluorescent coatings are then applied on the variable linear plate 2 and the fixed indicating plate 3, and they are fixed together on the signboard body 1. A steering device 5 is provided at the rear of one end of the variable linear plate 2 close to the fixed indicating plate 3, 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 linear plate 2 to rotate left and right, and the steering device 5 can be fixed in front of the signboard body 1, or fixed at the rear of the signboard body 1, or fixed inside the signboard body 1. According to the installation situation and aesthetic effect, the steering device 5 is arranged inside the signboard body in this example.

[0024] like Figure 3 and Figure 4As shown, it is a display effect diagram of the device of the utility model. 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 variable linear plate 2 to turn left, and the variable linear plate 2 turns left 90 degrees to form a left turn lane indication with the fixed indicator plate 3. 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 linear plate 2 to turn, and the variable linear plate 2 returns to the starting state to form a straight lane indication with the fixed indicator plate 3. In the example of the utility model, the variable lane indicator body 1 and the variable linear plate 2 and the fixed indicator plate 3 are detachable structures. During the later maintenance and replacement, they can be maintained and replaced separately, which is more convenient, simple, fast, and saves cost and time than the prior art that requires the overall replacement of the indicator when it is damaged.

[0025] like Figure 5 As shown, it is a circuit principle block diagram of the device of the utility model. 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, and 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 according to the photosensitive signal. 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 linear plate 2 and the fixed indicator plate 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 linear plate 2 rotates with the steering device 5, due to the light-emitting effect of the LED lamp 7, the utility model 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 utility model has the effect of saving energy consumption, which greatly improves the practicality of the device of the utility model.

[0026] 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.

[0027] Now most intersections have implemented intelligent traffic control. The control device 4 of the utility model can also be connected to the intelligent traffic control system, which can adjust the steering of the steering device 5 in real time according to the needs of different time periods and different traffic flows, and provide variable lane direction instructions.

[0028] The power module 8 of the device of the utility model 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 the solar panel. The power module 8 solves the problem that other indicating devices cannot work during power outages at night.
