Description

Technical Field

[0001] This utility model belongs to the field of traffic signal technology, specifically relating to traffic signal lights. Background Technology

[0002] In related technologies, traffic lights are signals that direct traffic. Conventional traffic lights mainly consist of a pole and a crossbar. The pole is fixed to the roadside or road surface, and one end of the crossbar is anchored to the side wall of the upper part of the pole with bolts. The crossbar is equipped with a signal light body consisting of red, green, and yellow lights. In existing technologies, because the position of the signal light body is generally relatively high, maintenance requires operators to use lifts or ladders to perform high-altitude operations, which has low safety.

[0009] Furthermore, it also includes: a signal pole, one end of which is connected to the second light pole; a signal display device, which is disposed at the other end of the signal pole; and an electrical connection wire, one end of which is electrically connected to the signal display device, and the other end of which passes sequentially through the interior of the signal pole, the interior of the second light pole, and the interior of the first light pole and is connected to a power source.

[0010] Furthermore, it also includes: a winding device adapted to wind or unwind the electrical connection wire.

[0011] Furthermore, the winding device includes: a winding roller, which is rotatably disposed inside the first lamp post.

One end of the electrical connecting wire extends to connect with the signal display device, and the other end of the electrical connecting wire passes through the connecting hole and the wire passage in sequence and is connected to a power source.

[0012] Furthermore, the winding device also includes a rotating bearing, the outer ring of which is connected to the inner peripheral wall of the wire passage, and the inner ring of which is connected to the electrical connection wire.

[0013] Furthermore, the signal pole includes: a first pole portion connected to the second light pole; and a second pole portion, one end of which is rotatably connected to the other end of the first pole portion, and the other end of the second pole portion is provided with the signal display device.

[0029] Example 1:

[0030] like Figures 1-3 As shown, this utility model provides a traffic signal light 1, including: a first light pole 10, a second light pole 20, and an external rotor motor. The bottom of the first light pole 10 is adapted to be connected to the ground. The second light pole 20 is movably sleeved on the outer periphery of the first light pole 10. A first mating part is provided inside the second light pole 20. The external rotor motor has a rotor and a stator. The stator is connected to the second light pole 20. The rotor is housed inside the first light pole 10 and a second mating part is provided on its outer peripheral wall. The first mating part and the second mating part are rotatably engaged. The external rotor motor works to drive the second light pole 20 to move relative to the first light pole 10 in the height direction.

[0031] In some embodiments, the first light pole 10 is the basic component of the traffic signal light 1. The bottom of the first light pole 10 is fixed to the ground to provide support for the entire traffic signal light 1. The second light pole 20 can move up and down along the first light pole 10. The second light pole 20 is provided with a first mating part inside. The rotor (rotating part) of the external rotor motor is located outside the stator (stationary part) (i.e., the rotor is rotatably sleeved on the outer periphery of the stator). The stator is connected to the second light pole 20, while the rotor is located inside the first light pole 10. A second mating part is provided on the outer periphery of the rotor. The first mating part and the second mating part can rotate and engage with each other, so that when the external rotor motor is working, the rotation of the rotor drives the second light pole 20 to move in the vertical direction relative to the first light pole 10.

[0032] It is understandable that the working principle of the external rotor motor is based on the law of electromagnetic induction. When the stator is powered, a magnetic field is generated. This magnetic field acts on the conductors on the rotor, generating a current, which in turn forms a reverse magnetic field, causing the rotor to rotate. Since the stator of the external rotor motor of this application is fixedly connected to the second lamp post 20, and the rotor is fitted with the internal structure of the first lamp post 10, when the motor starts, the rotor rotates. Due to the fit between the first and second fitting parts (usually a threaded fit), this rotational motion is converted into linear motion, that is, the second lamp post 20 moves up and down along the first lamp post 10, thereby realizing the adjustment of the height of the traffic signal light 1.

[0033] According to the present invention, the traffic signal light 1 uses an external rotor motor to move the second light pole 20 relative to the first light pole 10 in the height direction, thereby making the height of the traffic signal light 1 adjustable to adapt to different road environments or special situations (such as road maintenance, special events, special weather, etc. For example, in low visibility conditions, the visibility range of the traffic signal can be increased by raising the traffic signal light 1, or the height of the traffic signal light 1 can be lowered in road sections where tall vehicles frequently pass to prevent collisions). Moreover, the adjustable height of the traffic signal light 1 makes the maintenance of the traffic signal light 1 more convenient, avoiding the need to use a lift or build a ladder when maintaining the traffic signal light 1, thus improving the maintenance safety factor of the traffic signal light 1. Of course, by integrating the external rotor motor into the first light pole 10 and the second light pole 20, the volume of the traffic signal light 1 is not increased.

[0034] Example 2:

[0035] Based on Embodiment 1, the inner peripheral wall of the second lamp post 20 is provided with a first thread 21, which is configured as a first mating part. The outer peripheral wall of the outer rotor is provided with a second thread, which is configured as a second mating part. The first thread 21 and the second thread are mated.

[0036] It is understandable that the rotational motion of the rotor is converted into the linear motion of the second lamp post 20 by the meshing of the first thread 21 and the second thread. That is, when the rotor of the outer rotor motor rotates, the second thread on the outer peripheral wall of the rotor meshes with the first thread 21 on the inner peripheral wall of the second lamp post 20, thereby pushing the second lamp post 20 to move up and down along the first lamp post 10.

[0037] It is worth noting that the threaded drive has high precision and stability, enabling precise adjustment of the height of the traffic light 1. That is, by controlling the rotational speed and direction of the external rotor motor, the position of the second light pole 20 can be accurately adjusted. Moreover, the threaded engagement provides a reliable mechanical connection, ensuring that the movement of the second light pole 20 remains smooth and reliable even after long-term use and under various environmental conditions. Of course, the threaded drive has a simple structure, is easy to manufacture and maintain, and is relatively easy to inspect and repair even in outdoor environments. At the same time, the threaded drive has good anti-interference performance, maintaining good working condition even in harsh environments with dust, moisture, etc.

[0038] According to some embodiments of the present invention, the outer peripheral wall of the first lamp post 10 is provided with a slider, and the inner peripheral wall of the second lamp post 20 is provided with a groove 22 extending in the height direction, and the slider is movably disposed in the groove 22.

[0039] Understandably, the outer peripheral wall of the slider can restrict the inner peripheral wall of the slide groove 22, so that the slider can move stably relative to the slide groove 22 in the height direction, thereby allowing the second lamp post 20 to move stably relative to the first lamp post 10 in the height direction, preventing the second lamp post 20 from rotating during the movement.

[0040] Therefore, the cooperation between the slider and the groove 22 ensures that the second light pole 20 always maintains a straight line when moving up and down, avoiding malfunctions caused by the rotation of the second light pole 20 or other irregular movements. It also improves the movement stability of the second light pole 20 relative to the first light pole 10, ensuring that the movement of the second light pole 20 remains smooth and reliable under various environmental conditions. Of course, the cooperation between the slider and the groove 22 reduces the friction between the second light pole 20 and the first light pole 10, reduces wear, and extends the service life of the traffic signal light 1. At the same time, the design of the slider and the groove 22 is relatively simple, easy to manufacture and maintain, and also reduces the complexity of the traffic signal light 1, improving the overall reliability and economy.

[0041] Example 3:

[0042] Based on Embodiment 2, the traffic light 1 in this embodiment further includes: a signal pole, a signal display device 33, and an electrical connection wire. One end of the signal pole is connected to the second light pole 20, the signal display device 33 is disposed at the other end of the signal pole, one end of the electrical connection wire is electrically connected to the signal display device 33, and the other end of the electrical connection wire passes through the interior of the signal pole, the interior of the second light pole 20, and the interior of the first light pole 10 in sequence and is connected to the power supply.

[0043] In some embodiments, the signal pole extends horizontally, with one end of the signal pole fixedly connected to the top of the second light pole 20, and the other end of the signal pole is provided with a signal display device 33. The signal display device 33 is adapted to display traffic signals (such as red light, green light, yellow light, etc.) to guide traffic participants. The electrical connection line can provide power to the signal display device 33 to ensure that the signal display device 33 works normally.

[0044] It is worth noting that the stator of the external rotor motor is provided with a through hole in the height direction. The other end of the electrical connection wire passes through the interior of the signal pole, the interior of the second lamp pole 20, the through hole, and the interior of the first lamp pole 10 and is connected to the power supply.

[0045] It is understood that the signal display device 33 is connected to the second lamp post 20 via a signal pole. Thus, when needed, the external rotor motor can be controlled to drive the second lamp post 20 to rise or fall, thereby driving the signal display device 33 to rise or fall. When the signal display device 33 is raised, its visibility can be improved. When the signal display device 33 is lowered, it can facilitate the maintenance and repair of the signal display device 33.

[0046] According to some embodiments of the present invention, the signal pole includes: a first pole part 31 and a second pole part 32. The first pole part 31 is connected to the second lamp pole 20. One end of the second pole part 32 is rotatably connected to the other end of the first pole part 31. The other end of the second pole part 32 is provided with a signal display device 33.

[0047] Understandably, through the rotatable connection between the second pole 32 and the first pole 31, the operator can adjust the angle of the signal display device 33 as needed. For example, during installation, the angle of the signal display device 33 can be adjusted so that the signal display device 33 faces the best observation position, improving the visibility of traffic participants. Moreover, in certain special circumstances, such as temporary adjustments or maintenance, the direction of the signal display device 33 can also be changed by adjusting the angle of the second pole 32 to facilitate the maintenance of the signal display device 33.

[0048] Therefore, the rotatable second pole 32 design allows the signal display device 33 to face the optimal observation position, improving the visibility of traffic participants and enhancing the guiding effect of the traffic light 1. Moreover, by adjusting the angle of the signal display device 33, it can adapt to different installation environments and viewing angle requirements, making the traffic light 1 more flexible and versatile, suitable for various road conditions. Of course, the rotatable design simplifies the installation process and reduces dependence on specific installation positions. At the same time, during maintenance, the angle of the signal display device 33 can be easily adjusted for inspection and repair.

[0049] Example 4:

[0050] Based on Embodiment 3, the traffic light 1 further includes a winding device 40, which is adapted to wind or unwind electrical connection wires.

[0051] Understandably, the winding device 40 automatically winds up or unwinds the electrical connection wire by mechanical or electric means. When the second light pole 20 rises, the winding device 40 unwinds the electrical connection wire; when the second light pole 20 falls, the winding device 40 winds up the electrical connection wire to ensure that the electrical connection wire is always under appropriate tension and will not be damaged due to excessive stretching or loosening.

[0052] According to some embodiments of the present invention, the winding device 40 includes: a winding roller 41, which is rotatably disposed inside the first lamp post 10. The winding roller 41 is provided with a wire passage 411 that extends through the axial direction. The winding roller 41 is provided with a connecting hole 412 connecting the wire passage 411 and the outer peripheral wall of the winding roller 41. An electrical connecting wire is wound around the outer peripheral wall of the winding roller 41. One end of the electrical connecting wire extends to connect with the signal display device 33, and the other end of the electrical connecting wire passes through the connecting hole 412 and the wire passage 411 in sequence and is connected to the power supply.

[0053] Understandably, when the second lamp post 20 rises, the electrical connection cable needs to be released. At this time, the take-up drum 41 rotates, and the electrical connection cable is released from the outer peripheral wall of the take-up drum 41, thereby increasing the length of the electrical connection cable between the signal display device 33 and the take-up drum 41. Similarly, when the second lamp post 20 falls, the electrical connection cable needs to be retracted. At this time, the take-up drum 41 rotates and retracts the electrical connection cable between the signal display device 33 and the take-up drum 41. It is worth mentioning that the other end of the electrical connection cable passes through the connection hole 412 and the cable passage 411 in sequence and is connected to the power supply. Therefore, the length of the electrical connection cable between the take-up drum 41 and the power supply remains unchanged when the second lamp post 20 rises or falls.

[0054] Preferably, the other end of the electrical connection wire is provided with an electrical slip ring, which has a first rotating ring and a second rotating ring that can rotate relative to each other. The first rotating ring and the second rotating ring are electrically connected. The first rotating ring is electrically connected to the other end of the electrical connection wire, and the second rotating ring is adapted to be electrically connected to a power source.

[0055] According to some embodiments of the present invention, the winding device 40 further includes: a rotating bearing 42, the outer ring of which is connected to the inner peripheral wall of the wire passage 411, and the inner ring of which is connected to an electrical connection wire.

[0056] Understandably, the outer ring of the rotating bearing 42 is fixed inside the wire passage 411, and the inner ring is connected to the electrical connection wire. When the electrical connection wire moves during winding and unwinding, the inner ring can rotate freely, thereby greatly reducing the friction between the electrical connection wire and the inner wall of the wire passage 411. In other words, the use of the rotating bearing 42 ensures that the electrical connection wire will not be subjected to excessive friction during movement, reducing the wear of the electrical connection wire and extending its service life.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
