Description

Technical Field

[0001] The utility model relates to the technical field of traffic signal lamps, in particular to a signal lamp, a signal indication system and a rail transit system. Background Art

[0002] Rubber-tyred railroad trains are widely used in the rail transit industry due to their low transport volume, high density, and overhead tracks. The train is unmanned during normal operation. When the train's signal system fails, the train switches to backup mode and is manually driven. At this time, the driver needs to determine the driving information by observing the signal lights on the track.

[0003] Traditionally, the lights of signal lamps on the track are usually scattered in all directions. Train drivers may mistakenly judge the lights of signal lamps on adjacent sections of the track as indication signals of their own train, which may cause the train to run in the wrong direction and create a traffic safety hazard.

[0004] To avoid the above phenomenon, some signal lights on the track are covered with a hood on one side to cover the light on one side of the signal light, so that the light of the signal light is emitted from one side. However, this method can only make the signal light indicate the train in a certain direction, resulting in low flexibility in the use of signal lights and limited application scenarios. If the corresponding signal indication function needs to be realized, more signal lights need to be installed on the track, resulting in an increase in track design costs. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] It should be understood that the reference to "some embodiments" throughout the specification means that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the utility model. Therefore, the "in some embodiments" appearing in various places throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0032] The following describes in detail a signal light, a signal indication system and a rail transit system provided by the utility model by listing specific embodiments.

[0033] The utility model provides a signal lamp comprising a light-emitting component and a fixing component; the light-emitting component and the fixing component are movably connected, and the light-emitting component can move relative to the fixing component to change the light emitting direction of the light-emitting component.

[0034] Specifically, the applicable scenarios of the signal lights of the present invention include but are not limited to rubber-tired rail train systems, light rail systems, and railway system lights. The signal lights are installed on the tracks to indicate the trains running on the tracks. The signal lights include a light-emitting component and a fixing component. The light-emitting component is used to emit lights of different colors to indicate traffic signals. In terms of traffic lights, the indicator signals usually include three colors: red, yellow, and green. Therefore, the light-emitting component of this embodiment is mainly used to emit red light, yellow light, or green light. As for how the light-emitting component emits light of different colors, it is controlled by a software program. This control method belongs to the conventional means in the field of traffic light control, and the present invention does not pay attention to this. The fixing component is equivalent to the base of the signal light. The base is connected to the inner side of the track beam or the side of the track beam. The light-emitting component and the fixing component are movably connected. The light-emitting component can move relative to the fixing component. In the process of the light-emitting component moving relative to the fixing component, the light-emitting direction of the light-emitting component changes.

[0035] The switching of the indication direction of the signal light can be achieved by changing the light emitting direction of the light emitting component. If at time t1 or time period, the signal light needs to indicate the train in the first section, the signal light moves relative to the fixed part to emit light toward the first section. If at time t2 or time period, the signal light needs to indicate the train in the second section, the signal light moves relative to the fixed part to emit light toward the second section, thereby effectively improving the flexibility of the use of the signal light, broadening the applicable scenarios of the signal light, helping to reduce the overall number of signal lights arranged on the track, and controlling the track design cost. It should be noted that the movement of the light emitting component relative to the fixed part can rely on manual adjustment or on adjustment of drive components such as motors, which is not limited in this embodiment.

[0036] Optionally, refer to Figure 1 The light-emitting component includes a shell 1 and a light-emitting member 2, the light-emitting member 2 is connected to the inside of the shell 1, the shell 1 includes a light-shielding portion and a light-transmitting portion 10, and the light emitted by the light-emitting member 2 is emitted from the light-transmitting portion 10; the driving component is connected to the light-emitting component, and is used to drive the light-emitting component to move at least partially relative to the fixing member to change the light emission direction of the light-emitting component.

[0037] Specifically, the light-emitting component includes a shell 1 and a light-emitting element 2. The light-emitting element 2 is connected to the interior of the shell 1. The shell 1 is provided with a light-transmitting portion 10. The other areas of the shell 1 except the light-transmitting portion 10 are all light-shielding portions. In some embodiments, the shell 1 is a closed structure. The light-transmitting portion 10 on the shell 1 is made of a light-transmitting material and can transmit light. The other areas of the shell 1 except the light-transmitting portion 10 are made of an opaque material and cannot transmit light. The light-emitting element 2 is arranged in the shell 1. The light emitted by the light-emitting element 2 can pass through the light-transmitting portion 10 to realize the light emission of the light-emitting component. In other embodiments, the shell 1 is an open structure. The open area forms the light-transmitting portion 10 of the shell 1. The light-emitting element 2 is installed on the shell 1. The light emitted by the light-emitting element 2 can be emitted from the open area.

[0038] The driving assembly is used to drive the light-emitting component to at least partially move relative to the fixed component, wherein the driving assembly can drive the housing 1 to move relative to the fixed component, and can also drive the light-emitting component 2 to move relative to the fixed component, so as to change the light-emitting direction of the light-emitting component. In some embodiments, the light-emitting component 2 is fixedly connected to the housing 1, and the driving assembly is connected to the housing 1, and can drive the housing 1 to move. During the movement of the housing 1, the orientation of the light-transmitting portion 10 on the housing 1 will change accordingly, so that the light-emitting direction of the light-emitting component changes, thereby achieving the adjustment of the direction indicated by the signal light. In other embodiments, the driving assembly is connected to the light-emitting component 2, and can drive the light-emitting component 2 to move relative to the housing 1. At this time, the light-transmitting portion 10 can be set at different positions of the housing 1, so that the light emitted by the light-emitting component 2 can be transmitted from the light-transmitting portions 10 at different positions, thereby changing the light-emitting direction of the light-emitting component, thereby achieving the adjustment of the direction indicated by the signal light.

[0039] For trains in different sections on the same track, if the light-transmitting portion 10 on the shell 1 faces the first section, the signal light will indicate the train in the first section, and the train driver in the second section adjacent to the first section will see the light-shielding portion of the shell 1 and cannot see the light of the signal light, thereby achieving unilateral indication of the signal light, which will not cause visual interference to the train drivers in the adjacent sections of the track, can effectively avoid misjudgment by the driver, and improve the safety of train travel.

[0040] In summary, the light-emitting component of the signal light of the utility model includes a shell and a light-emitting part. The light-emitting part is connected to the inside of the shell. The shell is provided with a light-transmitting part and a light-shielding part. The light-shielding part and the light-transmitting part are located at different parts of the shell. The light-emitting part is used to emit lights of different colors to indicate traffic signals. The light emitted by the light-emitting part can be emitted from the light-transmitting part, but cannot be emitted from the light-shielding part, thereby realizing the unilateral indication of the signal light and will not cause visual interference to the train drivers on the adjacent sections of the track. At the same time, the driving component is connected to the light-emitting component, and can drive the light-emitting component to move at least partially relative to the fixed part to change the light emitting direction of the light-emitting component, thereby realizing the switching of the indication direction of the signal light, effectively improving the flexibility of the use of the signal light, and broadening the applicable scenarios of the signal light.

[0041] Optionally, the shell 1 includes two light-transmitting portions 10 arranged opposite to each other, and the light-emitting component 2 and the driving assembly are both arranged in the shell 1; the driving assembly is connected to the light-emitting component 2, and is used to drive the light-emitting component 2 to move in the shell 1, so that the light emitted by the light-emitting component 2 is emitted from one of the light-transmitting portions 10.

[0042] Specifically, the light-transmitting portion 10 is provided on at least two sides of the shell 1. Exemplarily, the light-transmitting portion 10 can be provided on opposite sides of the shell 1 to indicate the trains in the front and rear sections of the track. The light-transmitting portion 10 can be transparent glass. The shell 1 is provided with a window for installing the transparent glass during processing. The transparent glass is embedded in the window and fixedly connected to the shell 1, thereby forming the light-transmitting portion 10 on the shell 1. In some embodiments, the light-transmitting portion 10 can be made of frosted glass. Frosted glass is a kind of semi-transparent glass with a rough and uneven surface that has been ground with a hard object such as corundum or treated by chemical methods. The rough surface of frosted glass can cause diffuse reflection of light, and transmit light without seeing through, so that the light transmitted by the light-transmitting portion 10 is softer, which will not make the train driver feel glare, thereby improving the indication effect of the signal light.

[0043] The light-emitting element 2 and the driving assembly are both arranged in the housing 1. To facilitate their arrangement in the housing 1, the housing 1 can be set as a split structure, consisting of a base 11 and an upper cover 12. The base 11 is relatively large and has a receiving cavity. The light-emitting element 2 and the driving assembly are both arranged in the receiving cavity. The base 11 and the upper cover 12 can be made of hard metal, alloy or plastic, etc., and have good strength and rigidity, and can provide good protection for the components in the receiving cavity. In some embodiments, the base 11 and the upper cover 12 can be made of castings, such as cast iron, steel, aluminum, etc. The cast base 11 and the upper cover 12 have excellent strength and rigidity, and are corrosion-resistant and high-temperature-resistant. They can also provide effective protection for the components in the receiving cavity in outdoor wind, frost, rain and snow weather. The upper cover 12 and the base 11 can be fixedly connected together by fasteners, or by a clamping structure such as a hook or a clamping groove. The upper cover 12 acts as a cover for the accommodating cavity, which can prevent external water vapor, dust, etc. from entering the accommodating cavity and causing damage to the components in the accommodating cavity. In some embodiments, a sealing ring can be provided at the contact portion between the upper cover 12 and the base 11 to enhance the sealing effect between the upper cover 12 and the base 11, thereby further enhancing the protection effect of the components in the accommodating cavity.

[0044] The driving assembly is connected to the light-emitting element 2, and the driving assembly is used to drive the light-emitting element 2 to move in the housing 1. When the light-emitting element 2 moves to the target position, the light emitted by the light-emitting element 2 will irradiate the light-transmitting portion 10 and emit from the light-transmitting portion 10. At this time, the signal light is in a light-on state, which serves as an indication to the train driver; when the light-emitting element 2 moves to a non-target position, the light emitted by the light-emitting element 2 will irradiate the light-shielding portion of the housing 1, and the light cannot be emitted from the housing 1. At this time, the signal light is in a light-off state and cannot serve as an indication to the train driver. It should be noted that the above-mentioned target position refers to the position where the light-emitting element 2 irradiates toward the light-transmitting portion 10, which includes both the position where the light-emitting element 2 irradiates directly toward the light-transmitting portion 10 and the position where the light-emitting element 2 is inclined to the light-transmitting portion 10 for irradiation, and all positions except the target position are regarded as non-target positions, which include the position where the light-emitting element 2 is facing away from the light-transmitting portion 10 and the position where the light-emitting element 2 is inclined to the light-transmitting portion 10 but the light cannot irradiate to the light-transmitting portion 10. In addition, in the actual implementation scenario, the light-transmitting portion 10 on the shell 1 needs to be set toward the track section that the signal light needs to indicate, so that train drivers on this section can see the indication signal of the signal light, and train drivers on other sections cannot see the indication signal of the signal light.

[0045] Since the light-transmitting portion 10 is disposed on at least two sides of the housing 1, the light emitted by the light-emitting element 2 can be emitted from both sides of the housing 1. For example, the light-transmitting portion 10 is disposed on the first side and the second side of the housing 1. At the time t1 or in the time period, the driving component drives the light-emitting element 2 to move to the light-transmitting portion 10 facing the first side of the housing 1, and the light emitted by the light-emitting element 2 is emitted from the light-transmitting portion 10 on the first side, so that the signal light indicates the signal through the first side; at the time t2 or in the time period, the driving component drives the light-emitting element 2 to move to the light-transmitting portion 10 facing the second side of the housing 1, and the light emitted by the light-emitting element 2 can be emitted from the light-transmitting portion 10 on the second side, so that the signal light indicates the signal through the second side. Among them, t1 and t2 are different times or time periods, that is, the light emitted by the light-emitting element 2 can only be emitted from one light-transmitting portion 10 at a certain time or time period. Therefore, by driving the light-emitting element 2 to move in the housing 1 by the driving component, the light-emitting direction of the signal light can be changed, and the switching of the indication direction of the signal light is realized, which effectively improves the flexibility of the use of the signal light and broadens the applicable scenes of the signal light.

[0046] Optional, see Figure 1 The light-emitting component also includes: a diffuser 3; the incident surface of the diffuser 3 is arranged toward the light-emitting component 2, and the light emitted by the light-emitting component 2 is emitted from one of the light-transmitting portions 10 through the diffuser 3; the driving component is also connected to the diffuser 3, and when the driving component drives the light-emitting component 2 to move, the diffuser 3 moves synchronously with the light-emitting component 2.

[0047] Specifically, the diffuser 3 is disposed in the housing 1, specifically on the optical path of the light emitting element 2, and the incident surface of the diffuser 3 is disposed toward the light emitting element 2, and the light emitted by the light emitting element 2 will pass through the diffuser 3 and be emitted from any light-transmitting portion 10. In some embodiments, the diffuser 3 can be disposed near the light-transmitting portion 10, and the diffuser 3 is fixedly connected to the housing 1. In this case, two diffusers 3 need to be disposed in the housing 1, and one diffuser 3 is disposed corresponding to one light-transmitting portion 10. When the driving assembly drives the light emitting element 2 to move toward the light-transmitting portion 10 on any side, the light emitted by the light emitting element 2 will pass through the diffuser 3 on that side and be emitted from the light-transmitting portion 10 on that side.

[0048] In this embodiment, a diffuser 3 is connected to the driving assembly. In the process of driving the light-emitting element 2 to move, the driving assembly can also synchronously drive the diffuser 3 to move in the housing 1. The diffuser 3 moves synchronously with the light-emitting element 2. The diffuser 3 and the light-emitting element 2 together form a light-emitting unit. The light emitted by the light-emitting element 2 irradiates the incident surface of the diffuser 3 and is emitted from the exit surface of the diffuser 3. At this time, only one diffuser 3 needs to be arranged in the housing 1. The diffuser 3 moves synchronously with the light-emitting element 2. In the process of the driving assembly driving the light-emitting element 2 to move, the light emitted by the light-emitting element 2 will always pass through the diffuser 3, thereby saving the number of components required for the signal light and facilitating the installation and layout of the diffuser 3 in the housing 1.

[0049] The diffuser 3 can disperse the light emitted by the light emitting component 2, causing the light to deviate from the original propagation direction and scatter, thereby reducing the light focusing property of the light. When the light emitting component 2 and the diffuser 3 move to the target position, the light emitted by the light emitting component 2 passes through the diffuser 3 and irradiates onto a light-transmitting portion 10, and is emitted from the light-transmitting portion 10, thereby avoiding excessive visual impact on the train driver and alleviating the driver's visual fatigue. It should be noted that the above-mentioned target position refers to the position where the exit surface of the diffuser 3 and the light-transmitting portion 10 are close to being parallel to each other, and the position where the exit surface of the diffuser 3 faces the light-transmitting portion 10 and is at a certain angle to the light-transmitting portion 10, so as to ensure that the light emitted by the light emitting component 2 can pass through the diffuser 3 and be emitted from the light-transmitting portion 10. The specific position is not limited in this embodiment.

[0050] In this embodiment, there may be one driving assembly, which is connected to both the light emitting element 2 and the diffusing mirror 3, so as to achieve synchronous driving of the light emitting element 2 and the diffusing mirror 3. There may also be two driving assemblies, which are connected to the light emitting element 2 and the diffusing mirror 3, respectively, so as to achieve independent driving of the light emitting element 2 and the diffusing mirror 3.

[0051] Optionally, the driving assembly includes a movable part and a fixed part; the movable part is rotatably connected to the fixed part, the light-emitting part 2 and the diopter 3 are respectively fixedly connected to the movable part, and the fixed part is fixedly connected to the shell 1; the movable part rotates relative to the fixed part to drive the light-emitting part 2 and the diopter 3 to move in the shell 1.

[0052] Specifically, the fixed part is fixedly connected to the shell 1, and the fixed connection methods include but are not limited to welding, fastener assembly connection, snap connection, adhesive connection, etc. After the fixed part is fixedly connected to the shell 1, no relative movement can be generated between the fixed part and the shell 1. The movable part is rotatably connected to the fixed part, and the rotatable connection methods include but are not limited to shaft hole connection, hinge, electromagnetic induction connection, etc. The movable part can rotate relative to the fixed part, that is, the movable part can rotate with the shell 1. The movable part should rotate relative to the fixed part in the direction toward the light-transmitting part 10 or away from the light-transmitting part 10. The light-emitting part 2 is fixedly connected to the movable part, and the diopter 3 is also fixedly connected to the movable part. The fixed connection methods include but are not limited to fastener assembly connection, snap connection, adhesive connection, etc. During the rotation of the movable part relative to the fixed part, the light-emitting part 2 and the diopter 3 can be driven to move in the shell 1.

[0053] Optional, see Figure 1 The movable part includes a first coil assembly 4, and the fixed part includes a second coil assembly 5; when the first coil assembly 4 and the second coil assembly 5 are energized, the first coil assembly 4 moves relative to the second coil assembly 5 to drive the light-emitting element 2 and the diffuser 3 to move in the housing 1.

[0054] Specifically, the driving component adopts electromagnetic induction drive, the movable part includes a first coil component 4, and the fixed part includes a second coil component 5. Figure 1 As shown, a bracket 13 is provided in the housing 1, and the bracket 13 is assembled and connected to the housing 1 by fasteners, and the second coil assembly 5 is assembled and connected to the bracket 13 by fasteners. The bracket 13 can support and fix the second coil assembly 5, and can also control the height of the second coil assembly 5 in the housing 1. The first coil assembly 4 and the second coil assembly 5 are rotatably connected. Specifically, the first coil assembly 4 can be rotatably connected to the housing 1, indirectly realizing a relatively rotatable relationship between the first coil assembly 4 and the second coil assembly 5. The light-emitting element 2 and the diopter 3 are both arranged on the first coil assembly 4 and fixedly connected to the first coil assembly 4. When the first coil assembly 4 and the second coil assembly 5 are powered on, a magnetic field appears between the first coil assembly 4 and the second coil assembly 5. Under the action of the magnetic field, the first coil assembly 4 begins to move relative to the second coil assembly 5, thereby driving the light-emitting element 2 and the diopter 3 to move in the housing 1.

[0055] Specifically, the first coil assembly 4 and the second coil assembly 5 each include an iron core and a coil wound on the iron core. When the coil is energized, a current is generated. The surrounding current magnetizes the iron core and generates magnetic poles on the iron core. By controlling the current direction of the two coils in the first coil assembly 4 and the second coil assembly 5, the magnetic pole directions of the two iron cores can be controlled. Then, under the action of the same-direction magnetic poles repelling each other and the opposite-direction magnetic poles attracting each other, the first coil assembly 4 is rotated relative to the second coil assembly 5. Since the second coil assembly 5 is fixedly connected to the housing 1, the light-emitting element 2 and the diffusing mirror 3 are both arranged on the first coil assembly 4. Therefore, when the first coil assembly 4 rotates relative to the second coil assembly 5, the light-emitting element 2 and the diffusing mirror 3 are driven to move in the housing 1. In this embodiment, the light-emitting element 2 and the diffusing mirror 3 are driven to move in the housing 1 by electromagnetic induction. The driving method is more flexible. The movement direction of the light-emitting element 2 and the diffusing mirror 3 in the housing 1 can be flexibly adjusted by adjusting the current direction. The operation is simple, the response is fast, and the driving accuracy is high.

[0056] Optionally, the first coil assembly 4 includes an iron core and a coil wound around the iron core, and the light-emitting element 2 is connected in series with the coil.

[0057] Specifically, the light-emitting element 2 is connected in series with the coil in the first coil assembly 4, that is, when the coil is energized, the light-emitting element 2 is also energized to start lighting up, thereby simplifying the wiring structure in the signal light, reducing the wiring difficulty, and making it easier to process and design the signal light. In addition, when the light-emitting element 2 fails or is damaged, the coil in the first coil assembly 4 is also cut off and is in an open circuit state. At this time, even if the coils of the first coil assembly 4 and the second coil assembly 5 are energized, the first coil assembly 4 cannot rotate relative to the second coil assembly 5, that is, the light-emitting element 2 and the diffuser 3 cannot move in the housing 1, and the light cannot be emitted from the light-transmitting portion 10, and the signal light is in an off state, thereby realizing the error-proofing design of the signal light. When the light-emitting element 2, the first coil assembly 4 or the second coil assembly 5 fails, the light cannot be emitted from the light-transmitting portion 10, and the signal light is in an off state. According to the state of the signal light, personnel can determine that the signal light has a fault, thereby facilitating timely maintenance of the signal light.

[0058] Optional, see Figure 1 The first coil assembly 4 and the second coil assembly 5 are both arc-shaped structures, and the centers of curvature of the first coil assembly 4 and the second coil assembly 5 are both arranged toward the center of the shell 1; the arc-shaped structure of the first coil assembly 4 includes a first end, a second end, and a middle part located between the first end and the second end, the light-emitting element 2 is fixedly connected to the middle part, one end of the diffuser 3 is fixedly connected to the first end, and the other end of the diffuser 3 is fixedly connected to the second end.

[0059] Specifically, the first coil assembly 4 and the second coil assembly 5 are both arc-shaped structures, which essentially means that the iron cores in the first coil assembly 4 and the second coil assembly 5 are arc-shaped structures, the length of the first coil assembly 4 along its extension direction is greater than the length of the second coil assembly 5 along its extension direction, the first coil assembly 4 and the second coil assembly 5 are bent and extended in the same direction, and their centers of curvature are both arranged toward the center of the housing 1. The first coil assembly 4 is rotatably connected to the housing 1, and the rotationally connected portion is located on the same straight line as the center of curvature of the first coil assembly 4. The arc-shaped structure of the first coil assembly 4 includes a first end, a second end, and a middle portion located between the first end and the second end arranged along its bending extension direction, and along the bending extension direction of the arc-shaped structure, the distance from the middle portion to the first end is substantially the same as the distance from the middle portion to the second end. The light-emitting element 2 is fixedly connected to the middle portion, one end of the diffuser 3 is fixedly connected to the first end, and the other end is fixedly connected to the second end, and the cross section of the structure formed by the diffuser 3 and the first coil assembly 4 along the vertical direction is similar to a semicircle, and the light emitted by the light-emitting element 2 can be irradiated onto the incident surface of the diffuser 3. When the first coil assembly 4 and the second coil assembly 5 are powered on, the first coil assembly 4 rotates relative to the housing 1 , thereby driving the light emitting element 2 and the diffuser 3 to rotate synchronously in the housing 1 .

[0060] Optionally, the driving component also includes: a reset member; the reset member is fixedly connected to the first coil assembly 4, and the reset member is used to fix the first coil assembly 4 in the first position when the first coil assembly 4 and the second coil assembly 5 are powered off; when the first coil assembly 4 is in the first position, the light emitted by the light-emitting component 2 is irradiated to the shading portion of the shell 1 through the diffuser 3.

[0061] Specifically, the reset member is fixedly connected to the first coil assembly 4, and the fixed connection method includes but is not limited to fastener assembly connection, clamping, adhesive connection, etc. The reset member is used to fix the first coil assembly 4 in the first position when the first coil assembly 4 and the second coil assembly 5 are powered off. The reset member includes but is not limited to elastic components such as springs and elastic ropes, one end of which is fixedly connected to the housing 1, and the other end is fixedly connected to the first coil assembly 4. When the first coil assembly 4 is in the first position, the first coil assembly 4 drives the diopter 3 to move to the non-target position. The non-target position of the diopter 3 refers to all positions except the target position of the diopter 3. The target position of the diopter 3 has been described in the aforementioned embodiment and will not be repeated here. Exemplarily, the mirror surface of the diopter 3 and the light-transmitting portion 10 are close to being perpendicular to each other. At this time, the light emitted by the light-emitting member 2 is irradiated to the upper or lower part of the housing 1 through the diopter 3, and cannot be transmitted from the housing 1, and the signal light is considered to be in the off state. Alternatively, the mirror surface of the diffuser 3 is arranged to face away from the light-transmitting portion 10, and the light emitted by the light-emitting element 2 is irradiated to the side of the housing 1 away from the light-transmitting portion 10 through the diffuser 3, and the light cannot be transmitted from the housing 1, and the signal light is considered to be in the off state. Therefore, in this embodiment, the reset element can be arranged to maintain the signal light in the off state when the first coil assembly 4 and the second coil assembly 5 are powered off, thereby avoiding malfunction of the signal light.

[0062] Optional, see Figure 1 The reset member is a gravity rod 6, one end of which is rotatably connected to the shell 1, and the other end is fixedly connected to the middle part of the arc structure of the first coil assembly 4; when the first coil assembly 4 and the second coil assembly 5 are powered off, the gravity rod 6 is in a vertical state under the action of gravity to drive the first coil assembly 4 to be in the first position.

[0063] Specifically, the reset member adopts a gravity rod 6, which has a simple structure, low cost, and low design difficulty. One end of the gravity rod 6 is rotatably connected to the housing 1, and the rotationally connected position is consistent with the rotationally connected position of the first coil assembly 4 and the housing 1. The other end of the gravity rod 6 is fixedly connected to the middle of the arc structure of the first coil assembly 4, which is close to the position of the light-emitting member 2. The gravity rod 6 will be in a vertical state under the action of gravity. Therefore, when the first coil assembly 4 and the second coil assembly 5 are powered off, the gravity rod 6 will drive the first coil assembly 4 to move to the first position, thereby maintaining the signal light in the off state. In order to ensure the reset effect of the gravity rod 6, it is necessary to reasonably select the weight of the gravity rod 6 according to the weight of the first coil assembly 4, so as to ensure that the gravity rod 6 can maintain the first coil assembly 4 in the first position when the first coil assembly 4 and the second coil assembly 5 are powered off, and to ensure that the first coil assembly 4 can rotate smoothly relative to the second coil assembly 5 when the first coil assembly 4 and the second coil assembly 5 are powered on.

[0064] Optionally, the light-emitting component further includes: an indicator light 7 ; the indicator light 7 is disposed outside the shell 1 and fixedly connected to the shell 1 .

[0065] Specifically, the indicator light 7 is arranged outside the shell 1 and is fixedly connected to the shell 1. The fixed connection methods include but are not limited to welding, assembly connection, snap connection, adhesive connection, etc. The indicator light 7 is mainly used to emit light of a specific color, such as white light, etc. The light of the specific color is used to indicate that the signal light is currently indicating a train in a manual driving mode. If the light is off, it means that the signal light is currently indicating a train in an unmanned driving mode, which makes it easier for the driver to judge the indication signal of the signal light.

[0066] Optionally, the light emitting component further includes a soft light cover, which is disposed outside the housing 1 and covers the light transmitting portion 10 , and is used to soften the light emitted from the light transmitting portion 10 .

[0067] Specifically, the soft light cover is arranged on the outside of the light-transmitting part 10 and is fixedly connected to the shell 1. The fixed connection methods include but are not limited to fastener assembly connection, clip connection, adhesive connection, etc. The soft light cover can soften the light emitted by the light-transmitting part 10 and play the role of softening the light, thereby avoiding the visual impact of the train driver caused by the excessively bright light after focusing, causing visual fatigue of the driver, thereby further improving the driving safety.

[0068] The utility model also provides a signal indication system, comprising any one of the signal lights described above.

[0069] Specifically, the signal indication system includes the signal light of the aforementioned embodiment, which is in an outdoor environment to indicate the train. The signal indication system also includes a signal control panel, etc. The signal control panel is usually located indoors for personnel to operate. By operating the signal control panel, personnel can adjust the indication status of the signal light, etc. to meet different train driving scenarios.

[0070] Reference Figure 1 and Figure 2 The utility model also provides a rail transit system, comprising a signal light as described in any one of the above items, wherein the signal light is installed on the track beam.

[0071] Specifically, if Figure 2As shown, the rail transit system of this embodiment is mainly applicable to rubber-wheeled rail trains, including a track beam 300, a rubber-wheeled train 200 and a signal light 100 of any of the aforementioned embodiments. The rubber-wheeled train 200 includes a carriage 201 and a rubber wheel 202, etc. The signal light 100 is installed on the track beam 300. Specifically, the track beam 300 is a double-beam structure, and the signal light 100 is installed in the middle area of ​​the track beam 300 in the width direction. The middle area is located below the driving area on the track beam 300. In some embodiments, such as Figure 1 As shown, the bottom of the shell 1 of the signal light 100 is provided with a hanging ear 8, and the shell 1 can be installed on the track beam 300 through the hanging ear 8, so as to realize the installation and fixation of the signal light 100. The utility model installs the signal light 100 in the middle area of ​​the track beam 300 in the width direction. On the one hand, it can avoid the buildings around the track beam 300 from blocking the light of the signal light, and will not affect the indication effect of the signal light. On the other hand, there is no need to install a metal bracket on the outside of the track beam 300, which will not affect the stability of the track beam 300 structure. Furthermore, multiple signal lights 100 can be installed in the track beam 300, and the distance between two adjacent signal lights 100 can be about 3m to 5m, which is specifically set according to the length of the track beam 300 and the driving requirements, and this embodiment is not limited to this.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device.
