Description

Technical Field

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

[0002] Traffic lights are core control facilities in road traffic management. They provide clear and uniform light signals to road users (including drivers of motor vehicles, cyclists of non-motorized vehicles, and pedestrians) to ensure the orderly allocation of right-of-way at intersections. Pedestrian crossing traffic lights are specifically designed to ensure pedestrian safety when crossing the street and are typically installed at intersections or sections of road where pedestrian crossing demand is high.

[0003] With the increasing sophistication of urban traffic management needs, pedestrian crossing traffic lights require a growing amount of information to convey to pedestrians. In addition to basic "go / don't go" signals, they often need to integrate countdown displays, announcements (such as "yield to pedestrians," "waiting area reminders," etc.), and safety reminders (such as "don't go on a red light," "beware of turning vehicles," etc.). Therefore, existing technologies have developed complex traffic lights that combine different functional modules such as indicator lights, countdown screens, and text / graphic announcement screens into a single unit.

[0004] However, the aforementioned existing technologies still have the following shortcomings: First, maintenance is inconvenient. Complex traffic lights integrate multiple display devices, with a compact internal structure and complex wiring. When one of these devices (such as a countdown module or a notification screen) malfunctions, maintenance is cumbersome and time-consuming, requiring highly skilled maintenance personnel and increasing the time cost of traffic disruptions or control measures. Furthermore, the overly convenient access to maintenance doors on some traffic lights also hinders the protection of the internal equipment.

[0005] Second, there is a lack of emergency alternative capabilities. Traffic signals (i.e., basic lights such as red, yellow, and green used to directly indicate right-of-way) are the minimum necessary condition for ensuring safe passage at intersections. Even if auxiliary content such as countdown timers and announcements are temporarily unavailable, traffic signals can still operate normally, and the basic traffic order at intersections will not be affected. However, in the current design, once the basic traffic signal light malfunctions (e.g., the red light bulb is damaged and does not light up), other auxiliary equipment (such as countdown screens and announcement screens) cannot temporarily take over the function of the basic signal and must wait for repairs.

[0006] Third, alternative layouts can cause pedestrian confusion. Even if it is theoretically possible to temporarily simulate red or green light signals using software or hardware settings for an auxiliary device (such as a light head originally used to display a countdown), the location of this alternative display area differs from the original location of the traffic light head that users have long been accustomed to. This often causes significant confusion for pedestrians, especially those who frequently cross the intersection and have developed fixed observation habits and location dependencies. Summary of the Invention

[0007] The present invention aims to overcome the shortcomings of the prior art and provide an integrated traffic signal light.

[0008] Technical Solution: An integrated traffic signal light includes a fixed part, a movable part, and a signal indicator part. The fixed part includes a bottom flange, a column, a bottom frame, and a panel. The panel is equipped with a first sunshade, a second sunshade, a first light-transmitting plate, a second light-transmitting plate, a first display screen unit, a second display screen unit, and a control unit. Two plugs are installed on the back of the panel. Both the first and second sunshades have image acquisition units. The movable part includes a top plate, a bottom plate, a back plate, two side plates, and two side doors respectively installed on the two side plates. The panel and back plate... The plates are connected by an electric telescopic rod. A limit rod is fixed at the front panel, and a limit sleeve is fixed at the back panel. The signal indicator includes two slides with limit holes, a connecting shaft connecting the two slides, a rotating frame mounted on the connecting shaft, and two lamp head units. The two lamp head units are respectively mounted at both ends of the rotating frame and can rotate relative to each other. Each lamp head unit has a socket that mates with a plug, and one of the lamp head units is fixed with a counterweight. A connecting rod is fixedly connected between the slides and the back panel, and a horizontal limit rod passing through the limit hole is fixed at the front panel.

[0009] Furthermore, the plug and socket use a magnetic connection method.

[0010] Furthermore, the socket has a chamfer.

[0011] This allows the plug to be inserted into the socket more easily, achieving a better fit between the plug and the socket.

[0012] Therefore, the control unit can communicate remotely and control traffic lights.

[0013] In some embodiments, a touch screen unit is installed on the panel.

[0014] Therefore, a smaller touchscreen can be used as a control panel for maintenance personnel.

[0015] Furthermore, the control unit includes a controller and a wireless communication unit.

[0016] Furthermore, the side door has a handle.

[0017] In some embodiments, the back panel has a maintenance door with a mechanical lock.

[0018] The maintenance door is not allowed to be opened during normal maintenance. It can only be opened in an emergency, so that emergency maintenance can be carried out through the maintenance door when the electrical control fails in an emergency.

[0019] Furthermore, the image acquisition unit at the first sun shade can acquire the image of the first light-transmitting plate; the image acquisition unit at the second sun shade can acquire the image of the second light-transmitting plate.

[0020] By periodically acquiring images, it is possible to determine whether the lamp head unit is damaged.

[0021] Furthermore, the light head unit can be used to indicate traffic signals and can be used to display a countdown.

[0022] Furthermore, the connecting shaft is a cylindrical shaft, the rotating frame includes two rotating plates, the rotating plates have a first circular hole through which the connecting shaft passes and a second circular hole located at both ends of the rotating plates, and both sides of the lamp head unit have cylindrical protrusions that are inserted into the second circular holes.

[0023] Furthermore, the two plugs are a first plug located at the top and a second plug located at the bottom; the two lamp head units are a first lamp head unit and a second lamp head unit, and the counterweight is fixed to the first lamp head unit.

[0024] Furthermore, the traffic light can be in a first operating state and a second operating state. In the first operating state, the first plug is inserted into the socket of the first lamp head unit and the second plug is inserted into the socket of the second lamp head unit. In the second operating state, the first plug is inserted into the socket of the second lamp head unit and the second plug is inserted into the socket of the first lamp head unit.

[0025] Furthermore, when the traffic light is in its first operating state, the electric telescopic pole allows the backplate to move away from the panel, which in turn lowers the first lamp head unit and raises the second lamp head unit.

[0026] Thus, during this process, the first lamp head unit descends and the second lamp head unit rises.

[0027] Furthermore, in the first usage state, the first light head unit is used to display traffic signals, and the second light head unit is used to display a countdown; in the second usage state, the second light head unit is used to display traffic signals.

[0028] Furthermore, in the first usage state, both the first lamp head unit and the second lamp head unit abut against the back of the panel; in the second usage state, both the first lamp head unit and the second lamp head unit abut against the back of the panel.

[0029] Furthermore, four side protrusions are fixed to the panel, each side protrusion is fixedly connected to a first plate, and the first plate is fixedly connected to a second plate and a limiting slide rail; both sides of the first lamp head unit are hinged to a limiting mechanism via elastic reset hinge components, the limiting mechanism including a connecting block and a U-shaped block connected to the connecting block, the second plate being able to be inserted into the U-shaped block; the side panel has a rectangular opening, the side door is hinged to the side panel, each side door has two slot units, the slot unit including a first receiving groove for accommodating the side protrusion, a first limiting slot for inserting the limiting slide rail, a second receiving groove for accommodating the limiting slide rail, and a second limiting slot for inserting the limiting slide rail, when the limiting slide rail is inserted... When the sliding rail is inserted into the first or second limiting slot, the side door cannot be opened. When the limiting rail is located in the second receiving slot, the side door can be opened. The traffic light can be in maintenance mode and light head switching mode. In maintenance mode, the length of the electric telescopic rod is at the first length, each limiting rail is located in the corresponding second receiving slot, and each second plate is inserted into the corresponding U-shaped block. In light head switching mode, the length of the electric telescopic rod is at the second length, each limiting rail is inserted into the first limiting slot, the two U-shaped blocks of the first light head unit abut against the two connecting rods respectively, the horizontal height of the first light head unit is lower than that of the second light head unit, and the second length is greater than the first length.

[0030] Furthermore, the outer side of the slide has an embedding groove; a rubber embedding strip that can be embedded in the groove is fixed at the side door; both the embedding groove and the rubber embedding strip have arc surfaces.

[0031] Therefore, the rubber insert strip can cooperate with the insert groove, and external force is required to make the rubber insert strip leave or enter the insert groove, thus requiring maintenance personnel to manually open the side door.

[0032] Furthermore, the bottom flange is fixedly connected to the bottom end of the column, and the bottom frame connects the column and the panel; the bottom plate has a rectangular notch; the bottom frame includes a horizontal fixing plate fixedly connected to the top of the column, a horizontal extension plate fixedly connected to the column, and two vertical fixing plates fixedly connected to the horizontal fixing plate, the vertical fixing plates are fixedly connected to the panel, and the horizontal extension plates can be embedded in the rectangular notch of the bottom plate.

[0033] Furthermore, both the first and second light-transmitting plates are circular plates.

[0034] Furthermore, the first light-transmitting plate, the second light-transmitting plate, the first display screen unit, and the second display screen unit are distributed from top to bottom.

[0035] Furthermore, the electric telescopic rod has two parts; four limiting rods are fixed at the panel, and four limiting sleeves are fixed at the back plate, with the four limiting rods and four limiting sleeves corresponding one-to-one.

[0036] Furthermore, a limit stop is fixed to the end of the horizontal limiting rod.

[0037] Furthermore, a U-shaped sealing plate is fixed to the inner side of the side plate.

[0038] Furthermore, the U-shaped sealing plate is a metal plate, and a U-shaped sealing gasket is fixed at the U-shaped sealing plate.

[0039] In some embodiments, the U-shaped sealing plate is made of rubber material.

[0040] Furthermore, a U-shaped protruding frame is fixed to the outer side of the side plate.

[0041] Furthermore, a sealing frame is fixed to the front surface of the panel.

[0042] Furthermore, the sealing frame is made of rubber material.

[0043] Beneficial effects: Compared with the prior art, the present invention has the following advantages: 1. Enhanced Maintenance Convenience and Internal Protection: By incorporating a movable part controlled by an electrically operated telescopic rod and a side door structure, this invention greatly facilitates maintenance operations. When internal components need repair or replacement, simply controlling the electric telescopic rod to move the movable part allows the side door to open. Simultaneously, the invention utilizes a slot unit and a limiting slide rail mechanism to reliably lock the side door in a non-maintenance state, effectively preventing accidental opening due to vibration, wind pressure, or human error, thus providing more comprehensive protection for the various integrated display devices.

[0044] 2. Emergency Replacement Capability in Case of Critical Signal Failure: When a light head used to directly indicate traffic signals malfunctions, this invention can temporarily switch the light head, which was originally only used to display countdown information, to the function of indicating traffic signals. This can provide effective emergency traffic guidance before maintenance personnel arrive, avoiding intersection chaos caused by signal loss.

[0045] 3. User Habit Adaptability After Emergency Replacement: In implementing the aforementioned emergency replacement function, this invention further employs a gravity-based light head position switching method. This invention utilizes gravity as the driving force, ensuring that after switching, the light-emitting surface of the light head unit ultimately stabilizes at the original position of the basic traffic light head. In other words, the traffic signal ultimately observed by pedestrians is still emitted from their long-term, fixed location, avoiding misjudgment or confusion caused by changes in signal display position. This design is not only simple in structure, low in cost, and has a low failure rate, but more importantly, it fully respects the fixed observation habits formed by pedestrians who frequently cross the intersection.

[0050] like Figure 1-15As shown, an integrated traffic signal light includes a fixed part, a movable part, and a signal indicator part. The fixed part includes a bottom flange 1.8, a column 1.7, a bottom frame, and a panel 1. The panel 1 is equipped with a first sunshade 1.12, a second sunshade 1.13, a first light-transmitting plate 1.1, a second light-transmitting plate 1.2, a first display screen unit 1.3, a second display screen unit 1.4, and a control unit 1.5. Two plugs 1.15 are installed on the back of the panel 1. The first sunshade 1.12 and the second sunshade 1.13 each have an image acquisition unit 1.14. The movable part includes a top plate 2.1, a bottom plate 2.2, a back plate 2.6, two side plates 2.3, and two side doors 2.4 respectively installed on the two side plates 2.3. The panel 1 and the back plate 2.6 are connected by an electric telescopic rod 1.21. A limiting rod 1.19 is fixed at the panel 1, and a limiting sleeve 1.20 is fixed at the back plate 2.6. The signal indicator includes two slides 3.1 with limiting through holes, a connecting shaft 3.4 connecting the two slides 3.1, a rotating frame mounted on the connecting shaft 3.4, and two lamp head units. The two lamp head units are respectively mounted at both ends of the rotating frame and can rotate relative to the lamp head unit. The lamp head unit has a socket 3.9 that mates with the plug 1.15. One of the lamp head units is fixed with a counterweight 3.6.1. A connecting rod 3.2 is fixedly connected between the slides 3.1 and the back plate 2.6. A horizontal limiting rod 1.17 passing through the limiting through hole is fixed at the panel 1. The image acquisition unit 1.14 at the first sun visor 1.12 can acquire the image of the first light-transmitting plate 1.1; the image acquisition unit 1.14 at the second sun visor 1.13 can acquire the image of the second light-transmitting plate 1.2. The lamp head unit can be used to indicate traffic signals and can be used to display a countdown. The connecting shaft 3.4 is a cylindrical shaft, and the rotating frame includes two rotating plates 3.5. The rotating plates 3.5 have a first circular hole through which the connecting shaft 3.4 passes and second circular holes located at both ends of the rotating plates 3.5. The lamp head unit has cylindrical protrusions 3.8 on both sides that are inserted into the second circular holes. The two plugs 1.15 are a first plug located above and a second plug located below; the two lamp head units are a first lamp head unit 3.6 and a second lamp head unit 3.7, respectively, and the counterweight 3.6.1 is fixed to the first lamp head unit 3.6; the traffic light can be in a first use state and a second use state. In the first use state, the first plug is inserted into the socket 3.9 of the first lamp head unit 3.6, and the second plug is inserted into the socket 3.9 of the second lamp head unit 3.7; in the second use state, the first plug is inserted into the socket 3.9 of the second lamp head unit 3.7, and the second plug is inserted into the socket 3.9 of the first lamp head unit 3.6; when the traffic light is in the first use state, the back plate 2.6 is moved away from the panel 1 by the electric telescopic rod 1.21, which causes the first lamp head unit 3.6 to descend and the second lamp head unit 3.7 to rise.

[0051] Four side protrusions 1.16.1 are fixed to the panel 1. Each side protrusion 1.16.1 is fixedly connected to a first plate 1.16.2. The first plate 1.16.2 is fixedly connected to a second plate 1.16.4 and a limiting slide rail 1.16.3. Both sides of the first lamp head unit 3.6 are hinged to limiting mechanisms through elastic reset hinge components. The limiting mechanism includes a connecting block 3.6.2 and a U-shaped block 3.6.3 connected to the connecting block 3.6.2. The second plate 1.16... .4 can be inserted into the U-shaped block 3.6.3; the side plate 2.3 has a rectangular opening, the side door 2.4 is hinged to the side plate 2.3, each side door 2.4 has two slot units, the slot unit includes a first receiving groove 2.5.1 capable of accommodating the side protrusion 1.16.1, a first limiting slot 2.5.2 capable of being inserted into the limiting slide rail 1.16.3, a second receiving groove 2.5.3 capable of accommodating the limiting slide rail 1.16.3, and a [missing information - likely a device or component] capable of being inserted into the limiting slide rail 1.16.3. The second limiting slot 2.5.4 prevents the side door from opening when the limiting slide rail 1.16.3 is inserted into the first limiting slot 2.5.2 or the second limiting slot 2.5.4. The side door 2.4 can open when the limiting slide rail 1.16.3 is located within the second receiving slot 2.5.3. The traffic light can be in a maintenance state and a light head switching state. In the maintenance state, the length of the electric telescopic rod 1.21 is at the first length, and each limiting slide rail 1.16.3 is located within its corresponding second receiving slot. Within the slot 2.5.3, each second plate 1.16.4 is inserted into the corresponding U-shaped block 3.6.3; in the lamp head switching state, the length of the electric telescopic rod 1.21 is at the second length, each limiting slide rail 1.16.3 is inserted into the first limiting slot 2.5.2, the two U-shaped blocks 3.6.3 of the first lamp head unit 3.6 respectively abut against the two connecting rods 3.2, the horizontal height of the first lamp head unit 3.6 is lower than that of the second lamp head unit 3.7, and the second length is greater than the first length.

[0052] The outer side of the slide block 3.1 has an embedding groove 3.3; a rubber embedding strip 2.4.2 that can be embedded in the groove 3.3 is fixed at the side door 2.4; both the embedding groove 3.3 and the rubber embedding strip 2.4.2 have arc surfaces. The bottom flange 1.8 is fixedly connected to the bottom end of the column 1.7, and the bottom frame connects the column 1.7 and the panel 1; the bottom plate 2.2 has a rectangular notch; the bottom frame includes a horizontal fixing plate 1.10 fixedly connected to the top end of the column 1.7, a horizontal extension plate 1.11 fixedly connected to the column 1.7, and two vertical fixing plates 1.9 fixedly connected to the horizontal fixing plate 1.10. The vertical fixing plates 1.9 are fixedly connected to the panel 1, and the horizontal extension plate 1.11 can be embedded in the rectangular notch of the bottom plate 2.2. Both the first light-transmitting plate 1.1 and the second light-transmitting plate 1.2 are circular plates; the first light-transmitting plate 1.1, the second light-transmitting plate 1.2, the first display screen unit 1.3, and the second display screen unit 1.4 are distributed from top to bottom. There are two electric telescopic rods 1.21; four limiting rods 1.19 are fixed to the panel 1, and four limiting sleeves 1.20 are fixed to the back plate 2.6, with each limiting rod 1.19 and each limiting sleeve 1.20 corresponding to the other. A U-shaped sealing plate 2.3.1 is fixed to the inner side of the side plate 2.3. A U-shaped protruding frame 2.3.2 is fixed to the outer side of the side plate 2.3. A sealing frame 1.6 is fixed to the front surface of the panel 1.

[0053] like Figure 1-4 As shown, in the first operating state, the traffic light of this application has a first lamp head unit for indicating traffic signals, a second lamp head unit for displaying a countdown, and a first display screen unit and a second display screen unit for displaying announcements and prompts. This results in a high degree of integration for the traffic light equipment and the ability to display a wide range of information. At this time, because the limit rail is inserted into the second limit slot, the side door cannot be opened.

[0054] When maintenance is required, the electric telescopic rod can be used for driving, thus switching from the first use state to a second use state. Figure 8 The maintenance state shown indicates that the side door can be opened because the limit rail is located within the second receiving groove. Thus, as... Figure 9-10 As shown, the side doors on both sides are open for easy maintenance. At this time, because the second plate is inserted into the U-shaped block, the first lamp head unit will not descend due to the locking mechanism between the second plate and the U-shaped block. Therefore, after subsequent maintenance, when returning to the first operating state, the first lamp head unit will still face the first light-transmitting plate, and the second lamp head unit will still face the second light-transmitting plate.

[0055] The image acquisition unit can periodically capture images to determine whether the first and second lamp head units are in normal working order. When damage is detected, a remote signal can be sent to remind maintenance. Furthermore, when damage to the first lamp head unit is detected, the system can switch from the first operating state to the maintenance state. In this switch, the movable plate is moved a greater distance backward relative to the maintenance state. Figure 13 In the middle, the U-shaped block has not yet detached from the second plate. Figure 14 In the middle, the U-shaped block detaches from the second plate, allowing it to descend under the weight of the counterweight, and the U-shaped block will touch the connecting rod (such as...). Figure 14 As shown), since the U-shaped block is hinged to the first lamp head unit via an elastic reset hinge component, the U-shaped block will have a certain buffering effect when it hits the connecting rod. Furthermore, because the limiting slide rail is inserted into the first limiting slot, the side door is limited and will not be affected by the slight vibration caused by the U-shaped block hitting the connecting rod. Subsequently, when switching from the maintenance state to the second use state, the moving part moves forward, and the back plate pushes the first lamp head unit forward, eventually reaching the second use state (as shown). Figure 15 As shown in the figure, since the first light head unit is damaged and not in use, the second light head unit can be used to display traffic signals. At this time, the second light head unit faces the first light-transmitting plate, so the position of the traffic signal remains unchanged, which is more in line with the observation habits of pedestrians.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
