Description

Technical Field

[0001] The invention belongs to the technical field of anti-reflection films, and in particular relates to a black anti-reflection film and a subway shielding door panel structure. Background Art

[0002] When the subway is in operation, the environment in the tunnel is complex, especially in summer. The temperature of the tunnel can be much higher than that of the platform due to factors such as frequent friction between trains and heat dissipation of equipment. In winter, the opposite is true, and the tunnel is even colder. The shielding door with heat insulation function can block the heat exchange between the tunnel and the platform, allowing the platform to maintain a relatively comfortable and stable temperature, reducing the discomfort caused by the temperature difference for passengers, and eliminating the need to experience hot and cold weather while waiting for the train. In some existing special subway shielding doors, the glass part uses a technology similar to anti-reflective glass. When it is not powered on, it is black and opaque. After power is turned on, the glass will gradually become transparent. When passengers look at the track through the shielding door, the visual effect will be clearer, reducing the interference caused by glass reflection. During the operation of the anti-reflective film, when an electric field is applied, the liquid crystal molecules will rearrange. This process consumes electricity and generates a certain amount of heat. Therefore, this type of subway shielding door panel structure has the problem of poor heat dissipation performance.

DETAILED DESCRIPTION

[0025] like Figures 1 to 4 As shown, a black antireflection film disclosed in the present invention comprises a transparent conductive layer, a black electrochromic layer, an ion storage layer, an electrolyte layer, a protective layer and a transparent cooling layer 2 which are arranged in sequence. The transparent conductive layer adopts ITO, and the transparency in the visible light range is generally 80%-90%, the surface resistivity is low, and it has good conductivity and mechanical stability. The black electrochromic layer is a functional layer that can appear black or close to black during the electrochromic process. The basic principle is to change the chemical state and structure of the material through an electrochemical reaction, thereby changing the absorption and reflection characteristics of the material to light. The above layers are all prior art and will not be repeated here. Different from this, the present invention fixes the transparent cooling layer 2 on the surface of the protective layer, and the transparent cooling layer 2 comprises a plurality of cooling pipes arranged alternately horizontally and vertically, and the cooling pipes are filled with a coolant, and the coolant adopts ethylene glycol. In some other embodiments, the cooling pipe can be connected to a refrigeration device, the cooling of the cooling pipe can be achieved, and the black antireflection film 1 can be circulated and cooled.

[0026] At the same time, the present invention also discloses a subway shielding door panel structure, including the above-mentioned black anti-reflection film 1. Specifically, the subway shielding door panel structure also includes a back panel body 3, two side panels 4 installed on both sides of the back panel body 3, and a rear panel 5 installed between the two side panels 4 and parallel to the back panel. The back panel body 3 is located on the back side of the subway door. The side panels 4 are connected and installed to the subway door through flexible parts. A plurality of through holes 6 are provided on the surface of the back panel body 3, which can be used for ventilation. The structures of the two side panels 4 are exactly the same, and are used to close the sides of the back panel. The front and rear sides of the back panel and the side panels 4 are combined to form a heat dissipation space 9 to avoid the problem of poor heat dissipation effect caused by the anti-reflection film being close to the subway shielding door panel structure.

[0027] Furthermore, sliders 7 are respectively connected to both sides of the black anti-reflection film 1. With the normal direction of the back plate as the vertical direction, the sliders 7 can slide vertically. The sliders 7 are slidably arranged on the side plates 4. Since the two sides of the black anti-reflection film 1 are respectively connected to the sliders 7, the sliders 7 can drive the black anti-reflection film 1 to move vertically, thereby adjusting the distance between the black anti-reflection film 1 and the back plate.

[0028] Among them, a displacement control device 8 is installed on the back plate 5. After the displacement control device 8 controls the black anti-reflection film 1 to slide, a heat dissipation space 9 is formed between the black anti-reflection film 1 and the back plate body 3. Corresponding to the heat dissipation space 9, a blower 10 is opened on the side plate 4; the blower 10 can blow flowing gas into the heat dissipation space 9, thereby accelerating the flow of air in the heat dissipation space 9, thereby achieving heat dissipation.

[0029] The cooling pipe array is provided with a plurality of spiral pipes 11 connected with the cooling pipes. The tail ends of two adjacent spiral pipes 11 are connected by a short pipe, so that the coolant can flow between the spiral pipes 11. The spiral pipes 11 are made of elastic material and the axis of the spiral pipes 11 extends toward the side where the back plate body 3 is located. The back plate body 3 is provided with a stepped groove 12 which limits the spiral pipes 11. In a normal state, the spiral pipes 11 can be hidden in the stepped groove 12. When the spiral pipes 11 extend outward, when the subway vibrates during driving, the spiral pipes 11 can also play a certain damping role. By providing the spiral pipes 11, the device of the present invention can provide elastic pre-tension for the anti-reflection film when the displacement control device 8 is unloaded, thereby driving it to return to its original position, thereby ensuring the stability and aesthetic effect of the device when in use.

[0030] The spiral pipe 11 disclosed in the present invention is connected with the cooling pipe. The spiral pipe 11 extends into the heat dissipation space 9 and can be used for heat dissipation at the same time. Under the combined effect of air cooling and water cooling, the heat dissipation effect of the overall device is increased to meet actual use requirements.

[0031] In this embodiment, a protrusion 13 is fixed to the lower side of the black anti-reflection film 1, and the protrusion 13 corresponds to the through hole 6 one by one. The diameter of the protrusion 13 is adapted to the diameter of the through hole 6. When the black anti-reflection film 1 is not in use, the protrusion 13 normally cooperates with the through hole 6 and closes the through hole 6, thereby preventing impurities from entering and affecting the heat dissipation performance.

[0032] In this embodiment, a hole 14 and an air filling pipe 15 connected to the hole 14 are opened on the inner side of the back panel body 3, the hole 14 is connected to an air pump, and an air bag 16 connected to the air filling pipe 15 is installed in the back panel body 3. After the air bag 16 is expanded, it can extend into the heat dissipation space 9. By providing the air bag 16, the black anti-reflection film 1 can be buffered when the subway vibrates, thereby reducing the impact of the vibration on the black anti-reflection film 1.

[0033] In this embodiment, the two sides of the rear plate 5 are respectively hinged to the two side plates 4, the two sides of the back plate body 3 are respectively hinged to the two side plates 4, the two sides of the black anti-reflection film 1 are respectively hinged to the two sliders 7, and a support sensing component 17 is installed between the black anti-reflection film 1 and the side plates 4. The support sensing component 17 is electrically connected to the controller, and the controller is electrically connected to the air pump. When vibration acts on the support sensing component 17, the support sensing component 17 sends a signal to the controller, and the controller can control the air pump to start, and the airbag 16 expands from the inner side of the back plate body 3 to buffer the black anti-reflection film 1.

[0034] In this embodiment, the support sensing component 17 is obliquely installed between the black anti-reflection film 1 and the side plate 4. The support sensing component 17 includes a hard inner rod 18, a brittle outer rod 19, a clamping piece, a stress sensor 20, a threaded rod 21 and a locking piece 22. The hard inner rod 18 is made of a metal material that is not easy to break, and the brittle outer rod 19 can be made of a brittle material such as glass, which can ensure a certain initial support force. One end of the hard inner rod 18 is fixedly connected to the black anti-reflection film 1, and the other end of the hard inner rod 18 is installed in the brittle outer rod 19 through a clamping piece. The end of the brittle outer rod 19 is provided with a center hole. One end of the hard inner rod 18 extending into the brittle outer rod 19 is connected to a threaded rod 21 through a stress sensor 20. The threaded rod 21 passes through the center hole and is connected to the brittle outer rod 19 through a locking piece 22. The brittle outer rod 19 is detachably connected to the side plate 4.

[0035] When the subway is subjected to a large amplitude vibration, the vibration exceeds the threshold of the brittle outer rod 19, the brittle outer rod 19 is damaged, and a relative displacement occurs between the hard inner rod 18 and the brittle outer rod 19. At this time, the stress sensor 20 is acted upon by a force, thereby sending a signal to the controller. By setting the brittle outer rod 19 in a detachable connection mode, it is convenient to replace it when it is damaged, so as to prepare for the next vibration and make it more convenient to handle.

[0036] In this embodiment, the locking part includes a spring 23 and a ball 24. A radial groove 25 is provided on the inner side of the brittle outer rod 19. The bottom of the radial groove 25 is connected to the ball 24 through the spring 23. A locking groove 26 corresponding to the ball 24 is provided on the outer side of the hard inner rod 18. When the brittle outer rod 19 is inserted inward, the ball 24 can be easily inserted into the locking groove 26, which reduces the time for alignment and installation, can achieve automatic locking, and is more convenient to install.

[0037] In this embodiment, the blower 10 is installed on one of the side panels 4, and the position of the blower 10 corresponds to the heat dissipation space 9. A slag outlet 27 corresponding to the blower 10 is opened on the other side panel 4, which can facilitate ventilation and heat dissipation while also removing the residue of the brittle outer rod 19 and reducing foreign matter residue.

[0038] In this embodiment, the displacement control device 8 includes a memory alloy bar, the two ends of which are respectively connected to the back plate 5 and the black anti-reflection film 1. The memory alloy bar is used to sense the temperature of the surface of the black anti-reflection film 1. When the temperature increases, the memory alloy bar deforms and pulls the black anti-reflection film 1 away from the back plate body 3. The back plate 5 is made of heat-insulating material to prevent the temperature of the subway body itself from affecting the memory alloy bar.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
