Description

Technical Field

[0001] This invention relates to the field of traffic control technology, and in particular to a traffic light, a traffic signal control device, and a traffic signal control method. Background Technology

[0002] Currently, traffic control relies on traffic signal control devices, including traffic signal controllers and traffic lights. These devices control various traffic lights, typically red, green, and yellow. A red light indicates a prohibition, a green light indicates permission to proceed, and a yellow light indicates a warning. Traffic lights effectively manage traffic flow, improve road capacity, and reduce traffic accidents. The illumination of red, green, and yellow lights displays different traffic signals to achieve the goal of traffic control.

[0003] Publication No. CN204360574U discloses a traffic signal light, including a front shell assembly and a rear shell assembly. The front shell assembly specifically includes: several front covers, front cover connecting strips, and lamp core assemblies. The several front covers are spliced ​​and installed through the front cover connecting strips. The several front covers and the rear shell assembly are installed to form the outer shell of the traffic signal light. The lamp core assembly matches the front covers and is installed inside the outer shell. The rear shell assembly specifically includes: two side sealing plates, one rear sealing plate, and two end caps. The two side sealing plates are respectively installed on both sides of the rear sealing plate to form the rear cover of the traffic signal light. The two end caps are respectively installed on both ends of the rear cover to form the rear shell of the traffic signal light. One side of each of the two side sealing plates is provided with a first slot, and the two sides of the rear sealing plate are provided with a second slot. The first slot and the second slot cooperate to achieve a nested splicing installation. The inner surface of the two end caps is provided with a third slot that cooperates with the two ends of the rear cover. The two ends of the rear cover are nested into the third slot, and the edges of the end caps are seamlessly fitted with the rear cover. In this embodiment of the invention, the two side sealing plates and the rear sealing plate are nested and spliced ​​together through the cooperation of the first and second slots, while their ends are seamlessly inserted into the third slots of the end caps, thus making the rear shell waterproof. In addition, the entire rear shell consists of five parts, with a simple structure, convenient installation, and improved production efficiency.

[0004] In the aforementioned traffic lights, the indicator lights used to display different signals are fixedly connected as one unit. When one of the multiple indicator lights malfunctions, in order to quickly restore traffic signal control, the multiple indicator lights that are fixed together are usually replaced as a whole, so that the other usable indicator lights are not effectively utilized. Summary of the Invention

[0005] In view of this, it is necessary to provide a traffic light, a traffic signal control device, and a traffic signal control method to solve the technical problem in the prior art that the entire traffic light needs to be replaced when a single indicator light is replaced.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a traffic light, comprising:

[0007] At least two indicator lights are spaced apart, and the peripheral wall of the indicator lights is provided with multiple mounting structures, the mounting structures including at least two slots, and the at least two slots are located on both sides of the indicator lights;

[0008] At least one connecting component includes two first connectors and a second connector, the first connectors being capable of being inserted into the slots of two adjacent indicator lights, and the second connector being connected to one of the two first connectors and detachably connected to the other one.

[0009] In one embodiment, the first connector includes a first connecting portion and two snap-fit ​​portions. The two snap-fit ​​portions are connected to the first connector and can be inserted into the slots of two adjacent indicator lights. The opposing sides of the two snap-fit ​​portions are inclined, and the distance between the opposing sides of the two snap-fit ​​portions gradually decreases along the direction close to the first connecting portion. The second connector can provide the two first connectors with a clamping force to clamp the indicator lights, and during the process of the second connector driving the two first connectors to clamp, the two snap-fit ​​portions can push the two adjacent indicator lights closer to each other.

[0010] In one embodiment, the second connector includes a second connecting portion and a third connecting portion. One end of the second connecting portion is connected to a first connecting portion, and the other end is slidably passed through another first connecting portion. The third connecting portion is threadedly connected to the second connecting portion and is movable relative to the second connecting portion. The third connecting portion is disposed on the side of the first connecting portion away from the indicator light.

[0011] In one embodiment, the inner wall of the slot is provided with a positioning groove, which is arranged along the depth direction of the slot. The first connector also includes two positioning parts, which are connected to the snap-fit ​​part and are arranged in a one-to-one correspondence with the snap-fit ​​part. The positioning part can be slidably inserted into the positioning groove to limit the sliding direction of the snap-fit ​​part.

[0012] In one embodiment, the two positioning portions are respectively disposed on opposite sides of the two latching portions. One end of the positioning portion is connected to the latching portion, and there is an angle between the positioning portion and the latching portion. The other end of the positioning portion can close towards the latching portion and has a restoring elastic force after closing.

[0013] In one embodiment, the second connector includes a fourth connecting portion, a fifth connecting portion, a coil spring, and a connecting rope. The fourth connecting portion is disposed on the side of the first connecting portion opposite to another first connecting portion. The fourth connecting portion has a receiving groove opposite to the first connecting portion. The fifth connecting portion is connected to the fourth connecting portion and partially extends into the receiving groove. The coil spring is sleeved on the fifth connecting portion, and one end of the coil spring is connected to the fifth connecting portion. One end of the connecting rope is connected to one first connecting portion, and the other end can slide through another first connecting portion. The other end of the connecting rope is wound around the fifth connecting portion and connected to the other end of the coil spring.

[0014] In one embodiment, the fifth connecting portion is threadedly connected to the fourth connecting portion.

[0015] In one embodiment, the fourth connecting part has a first threaded hole communicating with the receiving groove, the fifth connecting part has an external thread and is threadedly connected to the first threaded hole, the outer wall of the fifth connecting part has a sliding groove along the axial direction of the first threaded hole, the second connecting member further includes a sleeve and a slide bar, the sleeve is slidably sleeved on the fifth connecting part and built into the receiving groove, the slide bar is built into the sleeve and guided along the sliding groove, one side of the slide bar is connected to the sleeve and the other side is slidably inserted into the sliding groove, the coil spring is sleeved on the sleeve, one end of the coil spring is connected to the sleeve and connected to the fifth connecting part through the sleeve and the slide bar, and the other end of the connecting rope is wound around the sleeve.

[0016] In one embodiment, the fifth connecting part is a bolt, and the second connecting member further includes a limiting nut. The limiting nut is threadedly connected to the bolt and disposed between the head of the bolt and the fourth connecting part. The limiting nut is used to limit the number of rotations of the bolt and the coil spring, and can limit the clamping force applied to the two first connecting members to the indicator light. Moreover, when the limiting nut abuts against the fourth connecting part, the limiting nut can apply a preload force to the bolt and the fourth connecting part.

[0017] The present invention also relates to a traffic signal control device, including the aforementioned traffic lights.

[0018] The present invention also relates to a traffic signal control method, comprising:

[0019] The camera transmits the images of the sidewalk it captures to the processing module;

[0020] The processing module determines whether there is a moving object by comparing the images before and after;

[0021] The camera transmits the images of the roadway it captures to the processing module.

[0022] The processing module determines the direction of movement of objects on the motor vehicle lane by comparing the images before and after.

[0023] When the processing module detects that the direction of movement of an object on the motor vehicle lane is toward the object moving on the sidewalk, the processing module outputs a display signal to the traffic lights, controlling the traffic lights to display a warning signal.

[0024] Compared with the prior art, the beneficial effects of the present invention include: when multiple indicator lights are connected, two indicator lights are placed side by side, two first connectors are disposed on both sides of the indicator lights, and the two first connectors are inserted into the slots of the indicator lights. Moreover, the first connectors are inserted into the slots of two adjacent indicator lights, and then the second connector is connected to one of the first connectors and detachably connected to the other first connector, thereby realizing the connection of adjacent indicator lights; moreover, after the two first connectors and the second connector are connected to the two adjacent indicator lights, the insertion structure of the first connector and the slot can restrict the movement of the first connector relative to the indicator light, prevent the indicator light from detaching from the first connector, and enable the connecting assembly to securely connect the two adjacent indicator lights;

[0025] The above structure enables detachable connection between adjacent indicator lights. When one of the multiple indicator lights malfunctions, the malfunctioning indicator light can be replaced directly on-site without having to replace multiple indicator lights at once.

[0026] Moreover, the number of traffic lights in the traffic lights can be set as needed, such as one, two, three, etc., and adjacent indicator lights can be connected through connecting components;

[0027] Mounting structures are provided on multiple sides of the indicator lights, allowing multiple indicator lights to be arranged horizontally or vertically. Since the indicator lights only need to be connected by slots, there will be no protruding connection structures between adjacent indicator lights when they are connected, and no protruding connection structures will interfere with the connection between adjacent indicator lights.

[0051] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0052] like Figures 1 to 19 As shown, the present invention provides a signal light, including at least two spaced-apart indicator lights 1 and at least one connecting component 2. The peripheral wall of each indicator light 1 has multiple mounting structures 1a, each including at least two slots a1 located on either side of the indicator light 1. The connecting component 2 includes two first connectors 21 and a second connector 22. The first connectors 21 can be inserted into the slots a1 of two adjacent indicator lights 1, and the second connectors 22 are connected to one of the two first connectors 21 and detachably connected to the other. It should be understood that the outer contours of the multiple indicator lights 1 can be the same or different, and the number and arrangement of the LEDs in the multiple indicator lights 1 can be the same or different; the number of connecting components 2 can be one, two, three, four, or five, etc.

[0053] When multiple indicator lights 1 are connected, two indicator lights 1 are placed side by side, and two first connectors 21 are placed on both sides of the indicator lights 1. The two first connectors 21 are inserted into the slots a1 of the indicator lights 1, and the first connectors 21 are inserted into the slots a1 of the two adjacent indicator lights 1. Then, the second connector 22 is connected to one of the first connectors 21 and detachably connected to the other first connector 21, thus realizing the connection of adjacent indicator lights 1. Moreover, after the two first connectors 21 and the second connector 22 are connected to the two adjacent indicator lights 1, the insertion structure of the first connector 21 and the slot a1 can restrict the movement of the first connector 21 relative to the indicator lights 1, preventing the indicator lights 1 from detaching from the first connectors 21, so that the connecting component 2 can stably connect the two adjacent indicator lights 1.

[0054] The above structure enables detachable connection between adjacent indicator lights 1. When one of the multiple indicator lights 1 fails, the faulty indicator light 1 can be replaced directly on site without replacing multiple indicator lights 1 at once.

[0055] Moreover, the number of indicator lights 1 in the signal light can be set as needed, such as one, two, three, etc., and adjacent indicator lights 1 are connected through connecting components 2;

[0056] Mounting structures 1a are provided on multiple sides of the indicator light 1, so that multiple indicator lights 1 can be arranged horizontally or vertically. Since the indicator light 1 only needs to be connected by slots a1, when adjacent indicator lights 1 are connected, there will be no protruding connection structure between adjacent indicator lights 1, and there will be no protruding connection structure interfering with the connection of adjacent indicator lights 1.

[0057] In one embodiment, the indicator light 1 is a cube. On one of the front and rear sides of the indicator light 1, an LED light is provided, and on the other side, an interface for powering the LED light and providing on / off signals is provided. This interface is connected to the traffic signal control electromechanical via a cable. The four circumferential sides of the indicator light 1 are provided with mounting structures 1a, so that the indicator light 1 can be spliced ​​in the horizontal or vertical direction.

[0058] In one embodiment, the first connector 21 includes a first connecting portion 211 and two snap-fit ​​portions 212. The two snap-fit ​​portions 212 are connected to the first connector 21 and can be inserted into the slots a1 of two adjacent indicator lights 1. The opposite sides of the two snap-fit ​​portions 212 are inclined, and the distance between the opposite sides of the two snap-fit ​​portions 212 gradually decreases along the direction close to the first connecting portion 211. The second connector 22 can provide the two first connectors 21 with a clamping force to clamp the indicator lights 1. During the process of the second connector 22 driving the two first connectors 21 to clamp, the two snap-fit ​​portions 212 can push the two adjacent indicator lights 1 closer to each other.

[0059] When it is necessary to connect two adjacent indicator lights 1, two first connectors 21 are placed on both sides of the indicator light 1, so that the snap-fit ​​part 212 is inserted into the slot a1. The inclined side of the snap-fit ​​part 212 abuts against the groove of the slot a1. The second connector 22 applies a clamping force to the two first connectors 21 to clamp the indicator light 1. During the process of the second connector 22 clamping the two first connectors 21, it will push the snap-fit ​​part 212 deeper into the slot a1. The inclined surface of the snap-fit ​​part 212 will apply a pushing force to the two adjacent indicator lights 1 to move closer to each other, so that the two adjacent indicator lights 1 move closer to each other until they are tightly pressed together. This prevents the two adjacent indicator lights 1 from moving towards or away from each other after being connected by the first connector 21 and the second connector 22, thus achieving a stable connection between the two adjacent indicator lights 1.

[0060] like Figure 2 and Figure 7 As shown, in one embodiment, the inner wall of the slot a1 is provided with a positioning groove a2, which is arranged along the depth direction of the slot a1. The first connector 21 also includes two positioning parts 213, which are connected to the snap-fit ​​part 212 and are arranged in a one-to-one correspondence with the snap-fit ​​part 212. The positioning part 213 can be slidably inserted into the positioning groove a2 to limit the sliding direction of the snap-fit ​​part 212.

[0061] Since the snap-fit ​​part 212 needs to be inserted into the slot a1, the size of the inserted part of the snap-fit ​​part 212 is smaller than the size of the slot a1, so that the snap-fit ​​part 212 can move within a small range relative to the slot a1. In order to limit the sliding direction of the snap-fit ​​part 212 relative to the slot a1, the positioning part 213 is inserted into the positioning groove a2, so that the positioning part 213 can only move along the guide of the positioning groove a2, so as to prevent the snap-fit ​​part 212 from shaking or moving randomly relative to the slot a1, and to prevent the outer surfaces of the two adjacent indicator lights 1 from being uneven after assembly.

[0062] like Figure 7 and Figure 8 As shown, in one embodiment, two positioning parts 213 are respectively disposed on opposite sides of two latching parts 212. One end of the positioning part 213 is connected to the latching part 212. There is an angle between the positioning part 213 and the latching part 212. The other end of the positioning part 213 can close towards the latching part 212 and has a resetting elastic force after closing.

[0063] Because the inclined side of the latching part 212 abuts against the opening of the slot a1, as the latching part 212 is inserted into the slot a1, it will push the two adjacent indicator lights 1 to move closer to each other. If both the positioning part 213 and the latching part 212 are rigid structures, the positioning part 213 will obstruct the two indicator lights 1 from moving closer to each other, creating a structural conflict with the latching part 212 clamping the two indicator lights 1. If too much space is reserved between the positioning part 213 and the inner wall of the slot a1, the positioning part 213 will not be able to abut against the inner wall of the positioning groove a2 during the insertion of the latching part 212 into the slot a1, causing the latching part 212 to move in a direction perpendicular to the positioning groove a2. However, in this application, when the first connector 21 is inserted into the slot a1, the positioning part 213 is first positioned... The positioning part 213 is inserted into the positioning groove a2, so that the other end of the positioning part 213 abuts against the inner wall of the positioning groove a2, and the locking part 212 is inserted into the slot a1. The inclined side of the locking part 212 abuts against the opening of the slot a1. As the locking part 212 goes deeper into the slot a1, the locking part 212 will push the two adjacent indicator lights 1 to move towards each other, and make the inner wall of the positioning groove a2 move towards the locking part 212. The inner wall of the positioning groove a2 squeezes the positioning part 213, making the positioning part 213 rotate towards the locking part 212. At this time, the positioning part 213 has a restoring elastic force and does not interfere with the two indicator lights 1 moving towards each other. Moreover, the positioning part 213 is always inserted into the positioning groove a2 and abuts against the inner wall of the positioning groove a2, which can prevent the locking part 212 from shaking relative to the slot a1.

[0064] It should be understood that the two positioning parts 213 can also be respectively set on the opposite side of the two snap-fit ​​parts 212. However, in this case, the positioning groove a2 should also be set on the side of the slot a1 near the edge of the indicator light 1, which will affect the structural strength of the indicator light 1.

[0065] like Figure 7 and Figure 8 As shown, in one embodiment, the end of the positioning part 213 away from the first connecting part 211 is curled to form a vortex structure 214, and the vortex structure 214 is located on the side of the positioning part 213 near the snap-fit ​​part 212. The vortex structure 214 can generate an elastic force that pushes the vortex structure 214 to reset after being squeezed.

[0066] During the insertion of the latching part 212 into the slot a1, the positioning part 213 moves along with the latching part 212. The vortex structure 214 on the positioning part 213 first slides into the positioning groove a2 and abuts against the inner wall of the positioning groove a2, preventing the part of the positioning part 213 inserted into the positioning groove a2 from being a pointed tip, and preventing the positioning part 213 from getting stuck at the opening of the positioning groove a2, thus facilitating the sliding of the positioning part 213 into the positioning groove a2. When the latching part 212 pushes the two adjacent indicator lights 1 closer to each other, the inner wall of the positioning groove a2 gradually approaches the latching part 212. At this time, the inner wall of the positioning groove a2 and the latching part... 212 compresses the vortex structure 214, causing it to be gradually compressed. As the vortex structure 214 is compressed, when it is necessary to remove two adjacent indicator lights 1, the compressive force applied by the second connector 22 to the two first connectors 21 is released. At this time, the vortex structure 214 resets under its own elastic force and pushes the locking part 212 out of the slot a1, making it easier for the locking part 212 to move in the direction of sliding out of the slot a1, avoiding the locking part 212 from being stuck in the slot a1, making it easier for the locking part 212 to disengage from the slot a1, and making it easier to replace the indicator light 1.

[0067] like Figure 9 As shown, in one embodiment, the second connector 22 includes a second connector 221 and a third connector 222. One end of the second connector 221 is connected to a first connector 211, and the other end can slide through another first connector 211. The third connector 222 is threaded to the second connector 221 and can move relative to the second connector 221. The third connector 222 is disposed on the side of the first connector 211 away from the indicator light 1.

[0068] When it is necessary to connect two first connectors 21 via the second connector 22, one end of the second connector 221 is connected to one of the two first connectors 211, the second connector 221 is slidably passed through the other of the two first connectors 211, and then the third connector 222 is threaded to the second connector 221. The third connector 222 is rotated and moved toward the indicator light 1. The third connector 222 pushes the first connector 211 toward the indicator light 1, so that the two first connectors 211 gradually clamp the two adjacent indicator lights 1, which can provide the two first connectors 21 with clamping force to clamp the indicator lights 1, and the snap-fit ​​part 212 connected to the first connector 211 gradually penetrates into the slot a1.

[0069] Furthermore, the second connecting part 221 is rod-shaped, and the peripheral wall of the second connecting part 221 is provided with external threads along the length direction. The third connecting part 222 is provided with a threaded hole relative to the second connecting part 221, and the third connecting part 222 is threadedly connected to the second connecting part 221 through the threaded hole.

[0070] By opening an external thread on the second connecting part 221 and opening a threaded hole on the third connecting part 222, the third connecting part 222 is threadedly connected to the second connecting part 221 through the threaded hole.

[0071] like Figure 16 and Figure 17 As shown, in one embodiment, the second connector 22 includes a fourth connecting portion 223, a fifth connecting portion 224, a coil spring 225, and a connecting rope 226. The fourth connecting portion 223 is disposed on the side of the first connecting portion 211 opposite to the other first connecting portion 211, and the fourth connecting portion 223 has a receiving groove 223a opposite to the first connecting portion 211. The fifth connecting portion 224 is connected to the fourth connecting portion 223 and partially extends into the receiving groove 223a. The coil spring 225 is sleeved on the fifth connecting portion 224, and one end of the coil spring 225 is connected to the fifth connecting portion 224. One end of the connecting rope 226 is connected to one first connecting portion 211, and the other end can slide through the other first connecting portion 211. The other end of the connecting rope 226 is wound around the fifth connecting portion 224 and connected to the other end of the coil spring 225. It should be understood that one end and the other end of the coil spring 225 refer to the two ends in the length direction of the coil spring 225 after it is unfolded.

[0072] Since the second connector 22 needs to connect the two first connectors 21 and provide the clamping force for the two first connectors 21 to clamp the indicator lights 1, the second connector 22 can pass between two adjacent indicator lights 1 or be set along the periphery of the indicator light 1. However, the force of the second connector 22 set along the periphery of the indicator light 1 is not as good as passing directly between two indicator lights 1. Moreover, the second connector 22 is not aesthetically pleasing when exposed. However, when the second connector 22 passes between two adjacent second connectors 22, if the part of the second connector 22 that passes between two adjacent indicator lights 1 is the screw in the above embodiment, it will occupy a large space and cause the gap between the two adjacent indicator lights 1 to be too large. Alternatively, it is necessary to open a groove on the two adjacent indicator lights 1 to accommodate the second connector 22 between the two adjacent indicator lights 1.

[0073] In this embodiment, when it is necessary to fix two adjacent indicator lights 1 using the second connector 22 and the first connector 21, one of the first connectors 21 is placed on one side of the indicator light 1, and the two snap-fit ​​parts 212 in the first connector 21 are respectively inserted into the slots a1 of the two adjacent indicator lights 1. Then, the fourth connector 223 is pulled, causing the fourth connector 223 to move away from the indicator light 1. At this time, the connecting rope 226 pulls the coil spring 225, and the other end of the connecting rope 226 gradually extends out of the receiving groove 223a. Then, the connecting rope 226 passes between the two adjacent indicator lights 1, and the other first connector... 21 is located on the other side of indicator light 1, and the two snap-fit ​​parts 212 in the other first connector 21 are respectively inserted into the slots a1 of the two adjacent indicator lights 1. Then, the second connector 22 is slowly released. Under the action of the elastic restoring force of the coil spring 225, the connecting rope 226 is wound around the fifth connector 224 until the fourth connector 223 abuts against the first connector 211. At this time, the coil spring 225 applies a clamping force to the two first connectors 21 to clamp the indicator light 1, thereby fixing the two adjacent indicator lights 1. Moreover, in the process of fixing the two adjacent indicator lights 1, only the fourth connector 223 needs to be pulled, which is more convenient.

[0074] In one embodiment, the fifth connecting portion 224 is threadedly connected to the fourth connecting portion 223.

[0075] If the coil spring 225 needs to apply a large clamping force to the two first connecting members 21, then the rigidity of the coil spring 225 needs to be large, making the coil spring 225 difficult to stretch. If the clamping force applied by the coil spring 225 to the two first connecting members 21 is small, then the fixation between the two adjacent indicator lights 1 is not very stable.

[0076] In this embodiment, to facilitate the stretching of the coil spring 225, a coil spring 225 that is easy to stretch is selected. At this time, the coil spring 225 applies an initial clamping force to the two first connecting parts 21. Then, the fifth connecting part 224 is rotated. During the rotation of the fifth connecting part 224, the coil spring 225 and the connecting rope 226 are continuously wound around the fifth connecting part 224, so that the clamping force applied by the coil spring 225 to the connecting rope 226 gradually increases until the two first connecting parts 211 clamp the indicator light 1. In this embodiment, the coil spring 225 can conveniently fix the two indicator lights 1 initially, so that the worker can free up his hands to further fix the two adjacent indicator lights 1.

[0077] like Figure 14 , 18As shown in Figure 19, further, the fourth connecting part 223 has a first threaded hole 223b communicating with the receiving groove 223a, the fifth connecting part 224 has an external thread and is threadedly connected to the first threaded hole 223b, the outer wall of the fifth connecting part 224 has a sliding groove along the axial direction of the first threaded hole 223b, the second connecting member 22 also includes a sleeve 227 and a slide bar 228, the sleeve 227 is slidably sleeved on the fifth connecting part 224 and built into the receiving groove 223a, the slide bar 228 is built into the sleeve 227 and is arranged along the guide of the sliding groove, one side of the slide bar 228 is connected to the sleeve 227 and the other side is slidably inserted into the sliding groove, the coil spring 225 is sleeved on the sleeve 227, one end of the coil spring 225 is connected to the sleeve 227 and connected to the fifth connecting part 224 through the sleeve 227 and the slide bar 228, and the other end of the connecting rope 226 is wound around the sleeve 227. It should be understood that the fifth connecting part 224 can be a bolt, screw, threaded rod, etc.

[0078] As the fifth connecting part 224 rotates, it will move along the axial direction of the first threaded hole 223b. The moving fifth connecting part 224 will drive the coil spring 225 and the connecting rope 226 to move. When the coil spring 225 moves to abut the inner wall of the receiving groove 223a, the coil spring 225 will restrict the fifth connecting part 224 from continuing to move. The coil spring 225 sleeved on the fifth connecting part 224 restricts the range of movement of the fifth connecting part 224, causing the fifth connecting part 224 to be unable to apply sufficient clamping force to the coil spring 225.

[0079] In this embodiment, when the fifth connecting part 224 rotates, the coil spring 225 is driven to rotate through the slide bar 228 and the sleeve 227. Since the sleeve 227 is slidably disposed on the fifth connecting part 224 via the slide bar 228, when the fifth connecting part 224 moves axially along the first threaded hole 223b, the sleeve 227 and the connecting rope 226 can be fixed axially along the first threaded hole 223b, preventing the coil spring 225 from restricting the rotation of the fifth connecting part 224. This allows the fifth connecting part 224 to apply sufficient clamping force to the coil spring 225. Moreover, when the sleeve 227, which is fixed axially relative to the first threaded hole 223b, winds the connecting rope 226, it can also prevent the fifth connecting part 224 from driving the connecting rope 226 to move axially along the first threaded hole 223b.

[0080] like Figure 14As shown, the fifth connecting part 224 is a bolt, and the second connecting member 22 also includes a limiting nut 229. The limiting nut 229 is threadedly connected to the bolt and is disposed between the head of the bolt and the fourth connecting part 223. The limiting nut 229 is used to limit the number of rotations of the bolt and the coil spring 225, and can limit the clamping force applied to the two first connecting members 21 to the indicator light 1. Moreover, when the limiting nut 229 abuts against the fourth connecting part 223, the limiting nut 229 can apply a preload force to the bolt and the fourth connecting part 223. The position of the limiting nut 229 in the axial direction of the bolt is set according to the stiffness of the coil spring 225, and the limiting nut 229 and the bolt are assembled at the factory.

[0081] During the rotation of the fifth connecting part 224, if there is no reference point, the clamping force applied to the coil spring 225 may be too large, causing the indicator light 1 to be damaged. If the clamping force applied to the coil spring 225 is too small, the adjacent indicator light 1 may become loose. In this embodiment, during the rotation of the fifth connecting part 224, the fifth connecting part 224 rotates until the limiting nut 229 abuts against the fourth connecting part 223. At this point, the fifth connecting part 224 cannot continue to rotate. The position of the limiting nut 229 limits the number of rotations of the coil spring 225, thereby limiting the amount of force applied to the coil spring by the bolt. The force of 225 ensures that the clamping force applied by the coil spring 225 to the two indicator lights 1 is within the preset range, avoiding excessive or insufficient clamping force on the two indicator lights 1. Moreover, since the limit nut 229 is threadedly connected to the bolt, during the process of the limit nut 229 abutting against the fourth connecting part 223, a pre-tightening force is applied to the fifth connecting part 224 and the fourth connecting part 223, preventing the continuous elastic force of the coil spring 225 from causing the fifth connecting part 224 to loosen relative to the fourth connecting part 223, and preventing the bolt from loosening and affecting the clamping effect on the two indicator lights 1.

[0082] like Figure 14 , 18As shown in Figure 19, furthermore, the first connecting part 211 near the fourth connecting part 223 of the two first connecting parts 21 has a limiting groove 211a. The limiting groove 211a is located on the side of the first connecting part 211 away from the indicator light 1. Two fixing grooves are formed at the bottom of the limiting groove 211a. The inner wall of each fixing groove forms a slot 211b. The fourth connecting part 223 can be inserted into the limiting groove 211a. The fourth connecting part 223 has two notches on the side opposite to the first connecting part 21. The two notches are located on both sides of the fourth connecting part 223. The connecting assembly 2 also includes two snap-fit ​​pieces 23. The snap-fit ​​pieces 23 are arranged one-to-one with the notches. The snap-fit ​​pieces 23 cover... The device includes a fixing strip 231 and a locking block 232. One end of the fixing strip 231 is connected to the inner wall of the notch. The other ends of the two fixing strips 231 can be bent towards each other and have an elastic force to return to their original position after bending. The locking block 232 is connected to the fixing strip 231. One side of the locking block 232 has an inclined surface, which is used to push the fixing strip 231 towards the other fixing strip 231 when the locking block 232 is inserted into the fixing groove. The side of the locking block 232 connected to the fixing strip 231 is a vertical surface perpendicular to the fixing strip 231. When the locking block 232 is engaged in the locking groove 211b, the vertical surface abuts against the inner wall of the locking groove 211b and is used to limit the movement of the locking block 232 in the direction of sliding out of the fixing groove. It should be understood that the fixing groove can be a groove with a square or polygonal cross-section.

[0083] During the process of connecting two adjacent indicator lights 1 via the first connector 21, the second connector 22, and the snap-fit ​​connector 23, when the fourth connector 223 moves towards the first connector 211 under the elastic force of the coil spring 225, the coil spring 225 drives the fourth connector 223 to be inserted into the limiting groove 211a. The limiting groove 211a can restrict the rotation of the fourth connector 223 and also restrict the fourth connector 223 from moving along the opening direction of the vertical fixing groove. The snap-fit ​​block 232 assembly is gradually inserted into the fixing groove. During the process of the snap-fit ​​block 232 being inserted into the fixing groove... The inclined plane pushes the fixing strip 231 to move closer to the other end of the fixing strip 231. When the locking block 232 moves to the slot 211b, the fixing strip 231 pushes the locking block 232 into the slot 211b under its own elastic force. At this time, the vertical surface abuts against the inner wall of the slot 211b, which can restrict the locking block 232 from sliding out of the fixing slot, thereby restricting the fourth connecting part 223 from moving away from the indicator light 1, and preventing the fifth connecting part 224 from sliding relative to the first connecting part 211 when rotating the fifth connecting part 224, so as to facilitate the rotation of the fifth connecting part 224.

[0084] When it is necessary to separate the fourth connecting part 223 from the first connecting part 211, the two fixing strips 231 are squeezed and bent in a direction that brings them closer to each other, so that the locking block 232 is disengaged from the slot 211b. At this time, the locking member 23 can slide out of the fixing slot, so that the fourth connecting part 223 can slide away from the first connecting part 211 in a direction away from the indicator light 1.

[0085] like Figure 3 As shown, in one embodiment, the back of the indicator light 1 is provided with a plurality of second threaded holes, and the indicator light also includes at least one fixing component 3. The fixing component 3 includes a fixing plate 31 and a clamp 32. The fixing plate 31 is provided with a plurality of fixing holes opposite to the second threaded holes, and the fixing holes are provided in a one-to-one correspondence with the second threaded holes. The clamp 32 is connected to the fixing plate 31.

[0086] The fixing component 3 can fix the indicator light 1 to the pole, bracket or other components.

[0087] The present invention also relates to a traffic signal control device, including the aforementioned traffic lights.

[0088] In one embodiment, the traffic signal control device further includes a traffic signal controller (not shown in the figure), which is electrically connected to the interface of each indicator light via a cable. The traffic signal controller is capable of controlling the pattern displayed by the traffic lights and their illumination and extinguishing.

[0089] The present invention also relates to a traffic signal control method, comprising:

[0090] The camera (not shown in the picture) transmits the captured images of the sidewalk to the processing module;

[0091] The processing module determines whether there is a moving object by comparing the images before and after;

[0092] The camera (not shown in the picture) transmits the image information of the motor vehicle lane to the processing module;

[0093] The processing module determines the direction of movement of objects on the motor vehicle lane by comparing the images before and after.

[0094] When the processing module detects that the direction of movement of an object on the motor vehicle lane is toward the object moving on the sidewalk, the processing module outputs a display signal to the traffic lights, controlling the traffic lights to display a warning signal.

[0095] The above method is used at intersections with cameras and traffic lights. If the processing module detects a vehicle approaching while pedestrians are walking on the sidewalk, it can control the traffic lights to display a warning signal, which can alert pedestrians that a vehicle is approaching and reduce the occurrence of safety accidents.

[0096] It should be understood that the processing module can be the traffic signal controller mentioned above, or other control devices that can control traffic lights and acquire signals from cameras.

[0097] It should be understood that cameras can be installed on sidewalks to take pictures of the sidewalks, and the presence and direction of movement of moving objects can be determined from the pictures. This is a common technique and will not be elaborated on in this application.

[0098] It should be understood that cameras that identify the direction of movement of objects on the motor vehicle lane can be installed on both sides of the pedestrian walkway. When an object moving towards the pedestrian walkway appears in the image on the camera, the processing module controls the traffic lights to display a warning signal. It should also be understood that cameras can be installed at other locations at intersections.

[0099] It should be understood that the processing module can control the traffic lights to display signals such as "X" that can serve as warnings. When the processing module detects that there is no moving object in the direction of the pedestrian crossing on the motor vehicle lane, the processing module controls the traffic lights to stop displaying warning signals. When the traffic lights display warning signals, it can be one of the indicator lights 1 that displays the warning signal, or it can be all the indicator lights 1 in the traffic lights that display the warning signal.

[0100] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
