Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the utility model, and not all embodiments.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0023] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0024] like Figures 1 to 6 As shown in the schematic diagram, this utility model provides an embodiment of a lighting and emergency guidance device. It can be installed on the front end of the steps of a seating platform 1. The lighting and emergency guidance device includes a light-emitting lamp body; a fixing mechanism including a light-transmitting cover 2 installed outside the lamp body; a variable guidance mechanism 4 including a connecting rod 41 and at least one elastic band 42, with both ends of the elastic band 42 connected to the light-transmitting cover 2. The connecting rod 41 is slidably connected to the light-transmitting cover 2 and is also connected to the elastic band 42. The connecting rod 41 can bend the elastic band 42, causing it to elastically deform. The elastic band 42 and the connecting rod 41 together form an arrow-shaped obstruction of the light-transmitting cover 2; and a driving mechanism 5 connected to the light-transmitting cover 2 to control the movement of the connecting rod 41. Normally, the lamp emits light to provide auxiliary illumination. The elastic band is arranged in a straight line and connected to the connecting rod, forming a first projection on the illuminated surface. In emergencies, it can be used for emergency evacuation direction guidance. The drive mechanism can control the movement of the connecting rod 41, causing it to pull the middle of the elastic band 42, bending it and forming an arrow-shaped second projection on the illuminated surface. This helps people quickly identify the evacuation direction in poor lighting or dark environments, serving multiple functions of illumination and guidance. When switching from emergency guidance to regular lighting, the force exerted by the drive mechanism 5 on the connecting rod 41 can be released. The deformed elastic band 42, under its elastic action, moves the connecting rod 41 back to its original position, restoring the elastic band 42 to a straight state, and the first projection is formed on the illuminated surface. Preferably, there are multiple elastic bands 42 arranged at intervals, with the middle of each elastic band 42 connected to the connecting rod 41. The material and elastic deformation capability of the elastic band 42 can be flexibly selected based on the frequency of use and in combination with the general technical knowledge of those skilled in the art, as long as the arrow-shaped guiding effect is guaranteed. This embodiment can be used for lighting and emergency guidance on the steps of public venues. The structure that combines arrow-shaped evacuation direction guidance with lighting can better play the warning and guidance functions, and is especially suitable for use in environments with poor lighting.

[0025] In this embodiment, the variable guiding mechanism 4 also includes a buffer section, and the end of the elastic band 42 is slidably connected to the light-transmitting cover 2 through the buffer section. The buffer section can prevent the elastic band 42 from being damaged due to overload deformation, effectively prevent the elastic band 42 from being overstretched and deformed or broken, extend its service life, and also improve the fault tolerance of drive control in case of accidents.

[0026] In this embodiment, the light-transmitting cover 2 has a sliding groove 46, and the buffer part includes an adjusting block 45 and an elastic element 43. The elastic band 42 is connected to the adjusting block 45, and the adjusting block 45 is slidably disposed in the sliding groove 46. The two ends of the elastic element 43 are respectively connected to the inner wall of the sliding groove 46 and the adjusting block 45. Preferably, the elastic element 43 is a spring. When the elastic band 42 is stretched to its deformation limit, the adjusting block 45 presses the elastic element in the sliding groove 46 to provide buffering. When the driving mechanism cancels the force on the connecting rod 41, the elastic element 43 drives the adjusting block 45 to move in the opposite direction through the restoring force and assists the elastic band 42 and the connecting rod 41 to return to their original positions. The adjusting block 45 has a groove 451 on its side to slide with the sliding groove 46.

[0027] In this embodiment, the light-transmitting cover 2 includes a light-transmitting housing 21 and a mounting frame 22. The light-transmitting housing 21 is connected to the lamp body, and the mounting frame 22 is connected to the front end face of the light-transmitting housing 21. The mounting frame 22 has a hollow area to transmit light. The opposite sides of the mounting frame 22 are respectively connected to the corresponding ends of the elastic band 42. That is, the opposite sides of the mounting frame 22 have an appropriate number of sliding grooves 46. The connecting rod 41 is slidably connected to the mounting frame 22. The light-transmitting housing 21 or the mounting frame 22 is connected to the driving mechanism 5.

[0028] In this embodiment, the fixing mechanism further includes a guide block 23, which is connected to the light-transmitting cover 2, and the connecting rod 41 slides through the guide block 23. In this embodiment, the length of the guide block 23 is adapted to the connecting rod 41. The guide block 23 provides sliding support for the connecting rod 41 and limits its sliding path, which ensures that the connecting rod 41 slides under the action of the driving mechanism or the elastic band 42, and also ensures that the reciprocating sliding path does not deviate, thus ensuring the formation of a stable arrow-shaped blocking structure. Preferably, the guide block 23 is connected to the mounting frame 22.

[0029] In this embodiment, the variable guiding mechanism 4 further includes a cleaning component 44 that contacts the light-transmitting cover 2, and the cleaning component 44 is connected to the elastic band 42. Preferably, the cleaning component 44 contacts the light-transmitting housing 21, and the cleaning component 44 is a strip of soft material, specifically a soft bristle strip. The elastic band 42 is connected to the soft bristle strip on the side facing the light-transmitting cover 2, and the soft bristle strip can fit against the light-transmitting cover 2. When the connecting rod 41 is controlled to move by the driving mechanism 5, the cleaning component 44 can move with the elastic band 42 to clean the surface of the light-transmitting cover 2. This embodiment can combine structural movement with cleaning function, and use the switching of emergency state to automatically clean the light-transmitting cover 2, better realize the lighting function, and reduce manual maintenance work.

[0030] In this embodiment, the driving mechanism 5 includes a pushing part 51 rotatably connected to the light-transmitting cover 2. When the pushing part 51 rotates, it intermittently contacts and pushes the connecting rod 41 to intermittently form an arrow-shaped obstruction. Preferably, the pushing part 51 intermittently contacts and pushes the connecting rod 41 during its rotation cycle, thereby driving the connecting rod 41 to intermittently pull and bend the elastic band 42. The pushed end of the connecting rod has a guiding slope. In this embodiment, the driving mechanism 5 can cooperate with the elastic band 42 to control the reciprocating motion of the connecting rod 41, thereby driving the elastic band 42 to alternate between straight and bent states, making the second projection of the guide appear intermittently, which can attract the attention of the crowd, make it easier to notice, and improve evacuation efficiency.

[0031] In this embodiment, the drive mechanism 5 further includes a power unit 52 connected to the light-transmitting cover 2. The output end of the power unit 52 is connected to the pushing part 51 to control the rotation of the pushing part 51. Preferably, the drive mechanism 5 further includes a support part 53, which is connected to the mounting frame 22 to support the power unit 52. The power unit 52 can be a motor, and the pushing part 51 is a cam connected to the output shaft of the motor. When the cam rotates, it can intermittently push the connecting rod 41.

[0032] In this embodiment, the controller 3 is connected to the light-transmitting cover 2 and electrically connected to the power unit 52. The controller includes a processing module, a wireless communication module, and a power supply module that are electrically connected to each other. The controller 3 is connected to the back-end terminal through the wireless communication module. The wireless communication module can receive instructions issued by the back-end terminal and control the start and stop of the drive mechanism 5 through the processing module. Wireless communication and control are existing technologies and will not be described further in this utility model.

[0033] In one application scenario of this embodiment, there are multiple lighting and emergency guidance devices connected in series by wires. They can be synchronously controlled by a unified control signal to ensure consistent evacuation direction guidance within the area. They can also work together to provide lighting for the steps on the seating platform 1.

[0034] The usage method of this embodiment includes the following steps:

[0035] Lighting and emergency guidance devices are installed on the front face of step 1 of the seating table.

[0036] In non-emergency situations or during normal lighting, the lamp body is controlled to emit light, which is emitted from the hollowed-out area of ​​the transparent housing 21 and the mounting frame 22, providing basic lighting for the steps of the seating platform 1 and forming a first projection on the illuminated surface.

[0037] In the event of an emergency or when evacuation direction guidance is required, the controller 3 receives an emergency signal from the back-end terminal and activates the power unit 52 of the drive mechanism 5. The drive mechanism 5 controls the movement of the connecting rod 41, which in turn causes the elastic band 42 to bend. The elastic band 42 and the connecting rod 41 together form an arrow-shaped shielding structure, creating a second projection on the illuminated surface that guides the evacuation direction. Preferably, in this embodiment, the second projection can be displayed intermittently with flashing indicators to better facilitate personnel detection and serve as a warning function. Specifically, the power unit 52 starts and controls the pusher 51 to intermittently push the connecting rod 41. The pusher 51 is a rotating cam. When the pusher 51 pushes the connecting rod 41 to move in the first direction, the connecting rod 41 can drive the elastic band 42 to bend and cause the elastic band 42 to undergo elastic deformation. The elastic band 42 and the connecting rod 41 together form an arrow-shaped shielding structure and form a second projection on the illuminated surface that can guide the evacuation direction. Since the side wall of the adjusting block 45 has a groove 451, the adjusting block 45 can only slide along the length direction of the slide groove 46. When the elastic band 42 is stretched to the deformation limit, the adjusting block 45 moves in the same direction as the connecting rod 41 and squeezes the elastic element 43. To buffer the movement, when the pushing part 51 is not in contact with the connecting rod 41, the elastic element 43, under its elastic action, drives the adjusting block 45 to reset and assists the deformation of the elastic band 42 in reacting against the connecting rod 41, causing the connecting rod 41 to reset and the elastic band 42 to return to a straight state. Through the intermittent pushing of the connecting rod 41 by the pushing part 51 and the elastic action of the elastic band 42, the connecting rod 41 performs periodic reciprocating linear motion, causing the first projection and the second projection to switch intermittently, that is, the arrow-shaped projection indicating the direction appears intermittently, creating a visual flashing change. Especially in poor lighting or dark environments, it can attract the attention of panicked people and guide them to leave quickly along the predetermined evacuation direction. Moreover, when the connecting rod 41 drives the elastic band 42 to move, the cleaning part 44 can rub against the light-transmitting cover 2 to clean the surface dust and dirt, ensuring the light transmission effect and lighting brightness.

[0038] When it is necessary to switch back to regular lighting, the power unit 52 is stopped, the driving mechanism 5 cancels the pushing action of the link 41, the elastic band 42 drives the link 41 to reset by its own elastic restoring force, the elastic band 42 returns to its natural straight state and is no longer bent, the illuminated surface forms the first projection, and the arrow indication disappears.

[0039] This embodiment can provide auxiliary lighting under normal circumstances and guide evacuation directions in emergencies. It is especially suitable for poor lighting conditions, making it easy for people to notice. It has a simple structure, which can improve the efficiency of crowd evacuation and enhance safety.
