Description

Technical Field

[0001] This utility model relates to the field of road traffic, and more specifically to a flip-type variable traffic sign. Background Technology

[0002] Variable traffic signs are intelligent transportation facilities that use modern technology to dynamically display traffic information. They can change the displayed content according to real-time traffic conditions, weather conditions, special events, or management needs, thereby guiding and managing traffic more flexibly and effectively. Currently, common variable traffic signs include electronic displays and LED displays. However, these two types of traffic signs consume a lot of electricity during daily use, and the replacement cost is high when they malfunction. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flip-type variable traffic sign.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A flip-type variable traffic sign includes a backing plate body, several flipping drive components, and several flipping assemblies. Each flipping assembly includes a fixed plate and a flipping plate. The fixed plate is fixedly connected to the backing plate body, and the flipping plate is rotatably mounted on the backing plate body. A fixed marking surface is formed on the fixed plate, and a flip marking surface is formed on the flipping plate. The flipping assembly has an unfolded state and an overlapped state. When the flipping assembly is in the unfolded state, both the flip marking surface of the flipping plate and the fixed marking surface of the fixed plate are exposed. When the flipping assembly is in the overlapped state, the flipping plate covers the fixed plate.

[0006] The flip drive component drives the flip plate to flip, causing the flip plate component to switch between an unfolded state and an overlapped state.

[0007] In this utility model, preferably, the flipping drive assembly includes an induction coil and a magnetic block. The induction coil is disposed on the side of the signboard body away from the flipping assembly. Each induction coil corresponds to a set of flipping assemblies. The magnetic block is fixedly connected to the corresponding flipping plate. When the induction coil is energized, it generates a magnetic field and drives the flipping plate to flip.

[0008] In this invention, preferably, the fixed marking surface and the flip marking surface are set as reflective surfaces to distinguish them from the back of the liner body and the flip plate.

[0009] In this utility model, preferably, the flip-type variable traffic sign includes a mounting housing and a sign body, the mounting housing and the sign body are fixedly connected, the liner body, the flip drive assembly and the flip assembly are all built into the mounting housing, and the sign body is provided with a transparent window, which is correspondingly provided with the flip assembly.

[0010] In this utility model, preferably, a control circuit board is installed inside the mounting housing, and each of the induction coils is electrically connected to the control circuit board.

[0011] In this utility model, preferably, a plurality of LED beads are installed on the control circuit board, and the LED beads are arranged in a one-to-one correspondence with the fixing plate. Both the liner body and the fixing plate are provided with through holes to accommodate the LED beads.

[0012] In this invention, preferably, an indicator area is formed on the sign body.

[0013] In this utility model, preferably, a rotating shaft is fixedly connected to the flip plate, the rotating shaft is rotatably mounted on the liner body, and the axis of the rotating shaft is vertically arranged.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model utilizes the magnetic field generated by the energized induction coil. By utilizing the force between the magnetic field and the magnetic block, when the energizing direction of the coil is changed, the direction of the magnetic field changes, and the force between the magnetic field and the magnetic block also changes accordingly, thereby driving the flip plate to flip, so as to switch the unfolded state and the overlapping state of the flip plate assembly. At the same time, when it is not necessary to switch the state, the current of the induction coil can be removed, and the sign can maintain the original display state, which is energy-saving and environmentally friendly.

[0016] 2. By utilizing multiple fixed sign surfaces and the unfolded state of flip sign surfaces, various display patterns can be switched. This method is low-cost. When a fault is detected in a certain flip component, only the corresponding structure needs to be replaced, without replacing the entire component, resulting in low maintenance costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] This embodiment provides a flip-type variable traffic sign; please refer to [link / reference]. Figures 1 to 3The system includes a liner body 3, several flipping drive components, and several flip-plate components. Each flip-plate component includes a fixed plate 4 and a flipping plate 5. The fixed plate 4 is fixedly connected to the liner body 3, and the flipping plate 5 is rotatably mounted on the liner body 3. The fixed plate 4 has a fixed marking surface 401, and the flipping plate 5 has a flip marking surface 501. The flip-plate component has an unfolded state and an overlapped state. When the flip-plate component is in the unfolded state, both the flip marking surface 501 of the flipping plate 5 and the fixed marking surface 401 of the fixed plate 4 are exposed. When the flip-plate component is in the overlapped state, the flipping plate 5 covers the fixed plate 4. The flipping drive components drive the flipping plate 5 to flip, allowing the flip-plate component to switch between the unfolded and overlapped states. The area of ​​the flip marking surface 501 is larger than the fixed marking surface 401, so that the flipping plate 5 can cover the fixed marking surface 401 after flipping onto the fixed plate 4.

[0028] In this utility model, preferably, the flipping drive assembly includes an induction coil 6 and a magnetic block 61. The induction coil 6 is disposed on the side of the signboard body away from the flipping assembly. Each induction coil 6 corresponds to a set of flipping assemblies. The magnetic block 61 is fixedly connected to the corresponding flipping plate 5. A rotating shaft 51 is fixedly connected to the flipping plate 5. The rotating shaft 51 is rotatably mounted on the liner body 3, and the axis of the rotating shaft 51 is vertically oriented. The flipping variable traffic sign involved in this application is installed vertically, and the rotating shaft 51 is also vertically oriented. In this state, if the current at both ends of the induction coil 6 is removed, the magnetic field will disappear. At this time, the flipping assembly can maintain its original indicating state and is not prone to deflection, thus ensuring good stability. When the induction coil 6 is energized, it generates a magnetic field and drives the flipping plate 5 to flip. Specifically, considering that the position of the magnetic block 61 will change after the flip plate 5 is flipped, in order to enable the magnetic field generated by the induction coil 6 before and after the flip to drive the flip plate 5 to flip, the position of the magnetic block 61 is set close to the rotating shaft 51. At the same time, when installing the induction coil 6, the center line of the induction coil 6 is set perpendicular to the liner body 3, and the center line of the induction coil 6 is made as close as possible to the center line of the rotating shaft 51.

[0029] When a forward current is applied to the induction coil 6, the generated magnetic field attracts the magnetic block 61, driving the flip plate 5 to flip towards the fixed plate 4. When a reverse current is applied, the magnetic field reverses direction, creating a repulsive force with the magnetic block 61, driving the flip plate 5 to flip away from the fixed plate 4. By switching the current direction, the flip plate assembly can be precisely switched between the unfolded and overlapped states. This invention utilizes the magnetic field generated by the energized induction coil 6. By utilizing the force between the magnetic field and the magnetic block 61, the direction of the magnetic field changes when the energization direction of the coil is changed, and the force between the magnetic field and the magnetic block 61 also changes, thereby driving the flip plate 5 to flip, thus switching between the unfolded and overlapped states of the flip plate assembly. At the same time, when the state switching is not required, the current to the induction coil 6 can be removed, and the sign can maintain its original display state, saving energy and being environmentally friendly.

[0030] In this invention, preferably, the fixed label surface 401 and the flip label surface 501 are configured as reflective surfaces to distinguish them from the back of the backing plate body 3 and the flip plate 5. To enhance the difference between the fixed label surface 401 and the flip label surface 501 and the surface of the backing plate body 3 and the back of the flip plate 5, and to avoid misinterpretation of the indicated content, they are typically configured as reflective surfaces, which can be achieved by attaching reflective stickers.

[0031] In this utility model, preferably, the flip-type variable traffic sign includes a mounting housing 2 and a sign body 1, the mounting housing 2 and the sign body 1 are fixedly connected, the liner body 3, the flip drive assembly, and the flip assembly are all built into the mounting housing 2, and the sign body 1 is provided with a transparent window 101, which is correspondingly provided with the flip assembly. The mounting housing 2 serves to protect the control circuit board 7 and the flip assembly.

[0032] In this invention, preferably, a control circuit board 7 is installed inside the mounting housing 2. This control circuit board 7 serves as the core control unit of the entire device. It adopts a mature circuit design architecture in the industry and integrates key components such as a microprocessor, power management module, and signal receiving and processing module, enabling efficient parsing, calculation, and execution of various instructions. Each of the induction coils 6 is electrically connected to the control circuit board 7.

[0033] The core function of the control circuit board 7 is to process various commands. When it is necessary to change the indication state of the flip panel assembly, it can precisely change the direction of the current applied to both ends of the induction coil 6 through the internal preset control logic. This change in the direction of the current will directly affect the magnetic field characteristics generated by the induction coil 6, thereby driving the flip panel assembly to complete the corresponding state transition action. The whole process is fast-responding and highly accurate, which can meet the real-time requirements of the device for the switching of indication states.

[0034] The control circuit board 7 is equipped with several LED beads 41. LED beads have a much higher luminous efficiency than traditional light sources and consume less power. They can directly convert most electrical energy into light energy, achieving a luminous efficiency of over 90%. Each LED bead 41 corresponds to one of the fixing plates 4, ensuring that each fixing plate 4 receives independent lighting indication, making the indication status of the flip-up assembly clearer and more precise. Both the liner body 3 and the fixing plates 4 have through holes to accommodate the LED beads 41. The size of the through holes matches the shape of the LED beads 41, securing them firmly and preventing displacement due to vibration or other factors during device operation, while also providing a smooth path for the light from the LED beads 41 to pass through. The light-emitting head of the LED bead 41 is exposed after passing through the through hole. This structural design allows the light emitted by the LED beads 41 to directly affect the external environment, improving the visibility of the indication. When the flip panel assembly is in the unfolded state, the control circuit board 7 outputs a power supply signal to the corresponding LED bead 41, causing the LED bead 41 to light up synchronously. The light emitted clearly indicates the current unfolded state of the flip panel assembly. When the flip panel assembly is in the overlapping state, the flip plate 5 flips onto the fixed plate 4. At this time, the control circuit board 7 promptly cuts off the power supply to the LED bead 41, causing the LED bead 41 to quickly turn off. Simultaneously, the flip plate 5 completely covers the LED bead 41, preventing false indications caused by external light reflection after the LED bead 41 is turned off, further ensuring the accuracy of the indication state. When it is necessary to change the indication state of the flip panel assembly, the control circuit board 7 can, according to the received command, synchronously power on or off the corresponding LED bead 41 through the internal power management module. During power supply, the power management module can provide a stable operating voltage and current to the LED bead 41, ensuring uniform brightness and avoiding unstable lighting due to voltage fluctuations. During power off, it can quickly disconnect the circuit, preventing unnecessary power loss and avoiding ineffective power consumption of the LED bead 41 in non-working states.

[0035] In addition, the control circuit board 7 also has overcurrent and overvoltage protection functions. When the lamp bead 41 or the induction coil 6 experiences abnormal conditions such as short circuit or overload, the control circuit board 7 can detect the abnormal signal in a very short time and quickly activate the protection mechanism to cut off the power supply to the corresponding circuit, thereby effectively protecting the control circuit board 7 and other related components from damage and improving the safety and reliability of the entire device. At the same time, the circuit layout of the control circuit board 7 has been optimized to reduce electromagnetic interference between lines, ensuring the stable operation of various functions and providing a strong guarantee for the long-term stable operation of the device.

[0036] In addition, LED 41 also has a flashing function. The control circuit board 7 can precisely control the flashing frequency and duty cycle of LED 41 through its internal pulse width modulation (PWM) module. The vehicle speed detection module is fixedly installed on the outer wall of the mounting housing 2 facing the oncoming traffic direction. Its signal output terminal is electrically connected to the signal receiving module of the control circuit board 7 through a shielded wire. When the vehicle speed detection module integrated into the device, such as a radar speed measurement module or an infrared speed sensor, detects that the vehicle speed exceeds a preset threshold, the vehicle speed detection module will transmit the overspeed signal to the microprocessor of the control circuit board 7 in real time. After receiving the overspeed signal, the microprocessor will immediately trigger the preset warning control logic, and output a pulse power supply signal to the LED 41 in the lit state through the PWM module, so that the LED 41 flashes at a set frequency, such as 5-10Hz. This flashing light can promptly warn speeding vehicles through visual stimulation, reminding drivers to slow down and improving road safety.

[0037] In this utility model, preferably, the flip-type variable traffic sign further includes a sign body 1, which is mounted on the side of the mounting housing 2 where the transparent window 101 is provided. An indicator area 102 is formed on the sign body 1, specifically used to identify the indication type of the sign. The indicator area (102) on the sign body 1 uses reflective ink to print text or symbols to clearly indicate the indication type of the sign, for example:

[0038] When used for variable lane indication, it is labeled with text such as "tidal flow lane" or "left turn / straight lane switch";

[0039] When used for parking space indication, it is marked with symbols such as "remaining parking spaces" and "underground garage";

[0040] When used for speed limit indication, numbers such as "speed limit in kilometers per hour" are displayed.

[0041] The indicator area 102 is arranged adjacent to the transparent window 101, and its size is 15%-20% of the total area of ​​the sign body 1, ensuring a clear association with the display content of the flip panel component.

[0042] Please see Figure 4 and Figure 5 This application can be specifically used for applications such as displaying the number of remaining parking spaces in a garage, indicating speed limits on highway ramps, and indicating road traffic direction, such as tidal flow lanes and reversible lanes. For example, when used for traffic indication in reversible lanes, it can indicate the first time period. Figure 4 The display status in (a) shows the second time period. Figure 4(b) The display state only needs to be preset with the time for switching the indication state. When entering the first or second time period, the control circuit board 7 will energize the induction coil 6 and switch the indication state of each flip panel component. For example, when used to display the number of remaining parking spaces in a garage, each induction coil 6 and flip panel component will be numbered in advance. According to the displayed data, the direction of the current of the induction coil 6 with different numbers can be preset. Then, the control circuit board 7 will energize the induction coil 6 and switch the indication state of each flip panel component.

[0043] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
