Description

Technical Field

[0001] This invention relates to the field of traffic signal technology, and more specifically, to an intelligent traffic signal. Background Technology

[0002] Traffic lights are core control devices in road traffic management, typically installed at key locations such as intersections and pedestrian crossings. They guide vehicles and pedestrians to pass in an orderly manner by periodically switching between red, yellow, and green signals, thereby ensuring road traffic safety and improving traffic efficiency. Traditional traffic lights mostly use single-color LED beads as light-emitting units, switching signals by illuminating different color groups of lights.

[0003] Existing traffic lights still suffer from the following significant technical shortcomings: First, their display capabilities are limited. Current mainstream traffic lights typically consist of arrays of low-pixel LEDs, whose light-emitting units can only achieve simple color switching and static display. Due to low pixel density and a single display mode, they cannot present complex graphics, text, or dynamic information (such as countdown numbers, animated directional arrows, emergency warning signs, etc.), making them ill-suited to the increasingly complex traffic scenarios. Second, they lack effective self-monitoring and fault diagnosis mechanisms. Most existing traffic lights lack real-time self-testing capabilities, unable to automatically monitor and report faults such as damaged internal LEDs, brightness decay, circuit abnormalities, or communication interruptions. Faults can only be discovered through manual inspections or public feedback, resulting in severely delayed fault response. Finally, maintenance relies on manual labor and cannot be self-repaired. When a traffic light malfunctions, maintenance personnel must arrive on-site to repair, replace components, or completely replace the light head. The lack of redundancy design or adaptive recovery functions prevents temporary self-repair through methods such as switching to backup LEDs or circuit reconfiguration, further reducing the system's reliability and availability. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a traffic signal light.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a traffic signal light, comprising a control unit, a housing, a movable panel, multiple lamp head units, a lamp head driving unit, a lamp head limiting unit, and a detection and repair unit; the housing is fixed with a first side mounting plate having a first through hole and a second side mounting plate having a second through hole; the lamp head unit includes a lamp head base, a first rotating shaft fixedly connected to the lamp head base and passing through the first through hole, and a second rotating shaft fixedly connected to the lamp head base and passing through the second through hole; the lamp head base has an equilateral triangular cross-section and three mounting surfaces, one of which is equipped with a display unit; the mounting surface has a magnetic socket and multiple positioning holes; the display unit has a magnetic plug and multiple positioning pins; the end of the first rotating shaft has a frustum-shaped groove; the lamp head driving unit includes a first lifting drive mechanism mounted on the first side mounting plate, a lifting seat driven by the first lifting drive mechanism, a first electric telescopic rod mounted on the lifting seat, a drive block mounted on the first electric telescopic rod, and a component fixed to the bottom of the lifting seat. The unit comprises an end plate, a sliding rail fixed to the lifting seat, a sliding seat mounted on the sliding rail, a first tension spring connecting the end plate and the sliding seat, a drive motor mounted on the sliding seat, and a drive wheel mounted on the drive motor. A synchronous belt connects the drive block and the drive wheel. The drive block includes a frustoconical portion that can be inserted into a frustoconical groove. The end of the second rotating shaft is fixed with a positioning plate having multiple positioning grooves. The lamp head limiting unit includes a pressure plate having multiple positioning protrusions and a second tension spring connecting the pressure plate and the second side mounting plate. The movable panel includes a panel body, and the panel body is connected to the first and second side mounting plates via a second electric telescopic rod. The detection and repair unit includes a second lifting drive mechanism and a lifting frame driven by the second lifting drive mechanism. The lifting frame includes a rectangular frame, a protruding plate fixedly connected to the rectangular frame, an image acquisition unit mounted on the protruding plate, a strip plate fixed to the rectangular frame, a third electric telescopic rod mounted on the strip plate, and a push plate mounted on the third electric telescopic rod. A display unit is installed inside the rectangular frame.

[0006] Furthermore, a limiting insert plate is fixed at the panel body, and both the first side mounting plate and the second side mounting plate have limiting slots into which the limiting insert plate is inserted.

[0007] Furthermore, the panel body has four limiting plates, and the first side mounting plate and the second side mounting plate each have two limiting slots.

[0008] Furthermore, the display unit is an LED display unit.

[0009] Furthermore, the control unit is also connected to a wireless communication unit.

[0010] Furthermore, the cross-section of the lamp holder is an equilateral triangle with rounded corners.

[0011] Furthermore, a bearing is connected between the first rotating shaft and the first through hole; a bearing is connected between the second rotating shaft and the second through hole.

[0012] Furthermore, the display unit is rectangular.

[0013] Furthermore, the inner side of the rectangular frame has an anti-slip coating or a rectangular frame-shaped rubber pad.

[0014] This allows the display unit to be installed more stably within the rectangular frame, maintaining its position as the rectangular frame rises and falls, and being pushed to the lamp holder by the push plate.

[0015] Furthermore, the second electric telescopic rod has four sections, with the first side mounting plate connected to the panel body via two second electric telescopic rods, and the second side mounting plate connected to the panel body via two second electric telescopic rods.

[0016] Furthermore, the panel body has multiple display through holes, and a transparent plate is installed at each display through hole; each display through hole corresponds to a sunshade plate connected to the panel body.

[0017] Thus, the transparent panel can both transmit light and protect the internal structure.

[0018] Furthermore, the display through-hole is rectangular; the transparent plate is rectangular.

[0019] Furthermore, two third electric telescopic rods are installed at the strip plate, and push plates are installed at the ends of the third electric telescopic rods; a magnetic block is provided in the positioning hole, and the positioning post can abut against and attract the magnetic block.

[0020] Thus, the push plate can push the display unit inside the rectangular frame under the drive of the third electric telescopic rod, ensuring that the display unit is accurately installed at the lamp holder; the abutment and attraction between the magnetic block and the positioning pin enhance the connection stability between the display unit and the lamp holder.

[0021] Furthermore, the lamp head unit has 6 units.

[0022] Furthermore, the panel body has three display through holes.

[0023] Furthermore, the first lifting drive mechanism includes a U-shaped frame fixed to the first side mounting plate, two first bearings respectively installed at the top and bottom of the U-shaped frame, a first lead screw connected between the two first bearings, a vertical guide rail fixed to the U-shaped frame, a driven gear installed on the first lead screw, a first motor installed on the U-shaped frame, and a driving gear installed on the first motor and meshing with the driven gear; the lifting seat has a first threaded hole that mates with the first lead screw and a vertical sliding groove that mates with the vertical guide rail.

[0024] Furthermore, the second lifting drive mechanism includes a first horizontal plate fixed to the panel body, a second horizontal plate fixed to the panel body, a vertical guide rod connected between the first and second horizontal plates, a second motor mounted on the first horizontal plate, a third motor mounted on the first horizontal plate, a second bearing mounted on the second horizontal plate, a third bearing mounted on the second horizontal plate, a second lead screw connecting the second motor and the second bearing, and a third lead screw connecting the third motor and the third bearing; the lifting frame has a vertical guide hole that cooperates with the vertical guide rod.

[0025] Furthermore, the lifting frame has two parts, an upper lifting frame and a lower lifting frame. The upper lifting frame has a second threaded hole that mates with the second lead screw and a first through-channel through which the third lead screw passes. The lower lifting frame has a third threaded hole that mates with the third lead screw and a second through-channel through which the second lead screw passes.

[0026] This design incorporates two lifting frames, thus providing two backup display units. Therefore, even if two of the commonly used display units fail, the signal lights can still function normally.

[0027] Furthermore, the second lead screw does not contact the first through channel; the third lead screw does not contact the second through channel.

[0028] Thus, the second lead screw can independently control the upper lifting frame, and the third lead screw can independently control the lower lifting frame.

[0029] Furthermore, the enclosure includes a top plate, a bottom plate, a back plate, and two side plates, with a maintenance door installed on the back plate.

[0030] Furthermore, both the first and second side mounting plates are fixedly connected to the back plate.

[0031] Furthermore, two fixing blocks are fixed to the back plate, and the fixing blocks have mounting through holes.

[0032] This provides mounting holes at the fixing block, facilitating the installation of traffic lights.

[0033] Furthermore, the multiple positioning grooves on the positioning plate are distributed in a ring with equal spacing, and the number is an integer multiple of 3; the multiple positioning protrusions on the pressure plate are distributed in a ring with equal spacing, and the number is an integer multiple of 3.

[0034] Furthermore, the positioning groove is hemispherical, and the positioning protrusion is hemispherical.

[0035] Thus, the positioning protrusion and the positioning groove cooperate to achieve positioning, and when the drive block drives the lamp holder to rotate, the positioning protrusion can disengage from the positioning groove.

[0036] Furthermore, the number of positioning grooves on the positioning plate is equal to the number of positioning protrusions on the pressure plate.

[0037] Furthermore, the positioning plate has 18 positioning grooves; the pressure plate has 18 positioning protrusions.

[0038] Furthermore, the drive block includes a frustum-shaped portion and a cylindrical portion connected to the frustum-shaped portion; the cylindrical portion of the drive block has a first annular groove, the drive wheel has a second annular groove, and the timing belt is installed between the first annular groove and the second annular groove.

[0039] Beneficial effects: 1. The traffic signal light of this application has 6 light head units, and the display unit can display richer signals. It can be used to display traffic lights, arrow lights, countdowns, text, traffic signs and other information, thereby improving the flexibility of the traffic signal light.

[0040] 2. The traffic light of this application can check whether the display unit is damaged, thereby reminding maintenance personnel to perform timely maintenance and ensuring the normal operation of the traffic light. In addition, the traffic light of this application can use a spare display unit to install in the lamp holder, thereby realizing automatic repair of the traffic light, greatly shortening the fault response time and ensuring the continuity of traffic signals.

Two fixing blocks 1.6 are fixed on the back plate 1.3, and the fixing blocks 1.6 have mounting through holes 1.6.1.

[0048] Working Principle: The traffic signal light of this application has six lamp head units, each including a lamp head base 4.1. The lamp head base 4.1 has three mounting surfaces, one of which houses a display unit 4.4, enabling signal display. Each display through-hole houses two lamp head units, which are then joined together to display the signal. The display unit 4.4 uses a color LED display, allowing for richer traffic signal displays, such as traffic lights, arrow lights, countdowns, text, and traffic signs. The display unit and the lamp head base are magnetically attached, allowing for both fixation and power supply / signal transmission via magnetic plugs and sockets.

[0049] During normal operation, the mounting surfaces of the six lamp holders 4.1, on which the display units 4.4 are installed, face the panel body, thus enabling signal display. Furthermore, due to the positioning effect of the positioning grooves of the positioning plate 4.5 and the positioning protrusions of the pressure plate 6, the lamp holders 4.1 will not rotate unexpectedly, thus achieving stable installation. Regular inspections are also possible. During inspections, the second electric telescopic rod 7.1 can be used to move the panel body 7 away from the back plate 1.3 by a certain distance. Then, by raising and lowering the lifting frame, the image acquisition unit 8.3 can acquire images of the display units 4.4 at the lamp holders 4.1, thereby determining whether the display units 4.4 are damaged.

[0050] When a display unit at a lamp holder unit malfunctions, the lamp holder drive unit can rise and fall to the lamp holder corresponding to the damaged display unit. The first electric telescopic rod extends, allowing the frustum-shaped portion of the drive block to insert into the frustum-shaped groove, thus rotating the lamp holder 120 degrees. Due to the cooperation of the positioning groove and the positioning protrusion, the lamp holder stops stably after rotating 120 degrees, and its position is fixed. At this time, there is no display unit on the mounting surface of the lamp holder facing the panel body. The second lifting drive mechanism then drives the lifting frame to descend to the lamp holder where the display unit is damaged. Next, the second electric telescopic rod shortens, bringing the panel body closer to the lamp holder, thus bringing the rectangular frame closer to the lamp holder. Then, the third electric telescopic rod extends, driving the push plate, which pushes the display unit at the lifting frame, moving it to the empty mounting position on the lamp holder. The unit is then magnetically fixed to the lamp holder, allowing this spare display unit to replace the damaged one. Therefore, the traffic light of this application can detect the display unit and can repair the traffic light by installing a spare display unit at the lamp holder of the damaged display unit. It has two lifting frames, effectively providing two spare display units. Each lamp holder has three mounting positions, providing greater repair space, and can still achieve automatic repair even if two display units are damaged. Even if a lamp holder fails two display units consecutively, automatic repair is still possible.

[0051] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
