[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The core of this utility model is to provide a door body, an electric sliding door, and a rail vehicle that can more reliably achieve the warning function.

[0029] For a specific embodiment of the door body provided by this utility model, please refer to the following: Figure 1 and Figure 2 The door body includes a door frame 1 and a light-transmitting door panel 2.

[0030] The door frame 1 is provided with a mounting groove 11, and the edge structure 21 of the door panel 2 is fixed in the mounting groove 11. Specifically, the door frame 1 can be a rectangular frame, and the door panel 2 is set in the rectangular frame, with the rectangular frame fully covering the edge of the door panel 2.

[0031] The edge structure 21 is provided with a receiving groove 24, and a light source 3 is provided in the receiving groove 24. Specifically, the shape of the receiving groove 24 is adapted to the shape of the light source 3, such as a strip groove, a square groove, or a round groove. The light source 3 can emit light through the edge structure 21 of the door panel 2 to the main body of the door panel 2 exposed in the mounting groove 11.

[0032] To achieve light transmission in door panel 2, it can be made of transparent or semi-transparent materials, such as glass, more specifically laminated tempered glass; acrylic sheets, polycarbonate sheets, etc., can also be selected as needed. Furthermore, the thickness of door panel 2 can be between 7 and 10 mm, for example, 8 mm.

[0033] It should be noted that the light emitted by the light source 3 needs to originate from the edge structure 21 on the door panel 2 and be emitted to the main body exposed in the mounting groove 11 to ensure that passengers can see the light emitted by the light source 3. Optionally, the light source 3 can face the peripheral surface 22 of the door panel 2, and the light emitted by the light source 3 enters the door panel 2 through the peripheral surface 22. Specifically, the direction of entry can be perpendicular to the thickness direction of the door panel 2, or it can have a small angle relative to the direction perpendicular to the thickness direction. Here, the two surfaces of the door panel 2 perpendicular to the thickness direction are two end surfaces 23, and the surface located between the two end surfaces 23 is the peripheral surface 22.

[0034] At this point, by adding a light source 3 to the door body, the light projected by the light source 3 onto the door panel 2 serves as a warning signal. The light source 3 is built into the mounting groove 11 on the door frame 1, and is protected by the door panel 2 and door frame 1, effectively preventing it from falling off and ensuring a more reliable warning function. Furthermore, the built-in design of the light source 3 does not occupy additional space outside the door body; positioning and assembly can be completed simply by adding a receiving groove 24 to the door frame 1, making assembly convenient. In addition, when applied to vehicles, adding lighting effects to the door body can enhance the aesthetics and technological feel of the vehicle interior.

[0035] Furthermore, to facilitate the assembly of the light source 3, the door panel 2 includes a door panel body 25, and the edge structure 21 includes a U-shaped edge interlayer 211 that wraps around the edge of the door panel body 25. Specifically, it can be an adhesive layer, and a receiving groove 24 is formed on the edge interlayer 211. The edge interlayer 211 can be used to bond the door panel body 25 and the door frame 1, ensuring the firmness of the connection between the door panel body 25 and the door frame 1. Additionally, it can also serve a sealing function. By forming the receiving groove 24 on the edge interlayer 211, processing is convenient, and damage to the door frame 1 and the door panel body 25 can be reduced. At the same time, since the light source 3 can be assembled into the door panel 2 and then integrally assembled into the door frame 1 along with the door panel body 25, the assembly difficulty can be reduced, and the need for modification of the door frame 1 due to the installation of the light source 3 can be minimized.

[0036] The door panel body 25 can be made of light-transmitting panels such as glass or acrylic. The edge of the door panel body 25 is also part of the edge structure 21, and it is fixed in the mounting groove 11 together with the edge interlayer 211. The remaining part of the door panel body 25 is exposed in the mounting groove 11 and the door frame 1, and it can be regarded as the main body of the door panel 2.

[0037] In addition, depending on assembly requirements, the edge interlayer 211 can also be set as or include a wood layer, rubber layer, or other filling layer to meet the needs of sound insulation and assembly. Furthermore, the edge interlayer 211 can be separately connected to the door panel body 25, or the two can be integrally formed.

[0038] Specifically, when the light source 3 is installed in the receiving groove 24, it can be bonded and fixed to ensure a firm fixation. For example, by applying double-sided adhesive (specifically 3M double-sided adhesive) to both ends of the light source 3 on the thickness direction of the door panel 2, during installation, the double-sided adhesive is first applied to the light source 3, which can be considered as an integral part of the light source 3. The sticker on the surface of the double-sided adhesive is then peeled off, and the light source 3 is placed in the receiving groove 24. By pressing the edge structure 21 towards the light source 3 in the thickness direction of the door panel 2, the bonding and fixation can be completed. At this time, for ease of assembly, the receiving groove 24 in the thickness direction of the door panel 2 can be slightly larger than the size of the light source 3 so that the double-sided adhesive can smoothly enter the receiving groove 24 after the sticker is peeled off. The bonding is then achieved by slightly deforming the edge structure 21 by pressing. Alternatively, the light source 3 can be placed in the corresponding receiving groove 24 first, and then glue can be injected into the gap between the receiving groove 24 and the light source 3, which can also achieve bonding and fixation.

[0039] Alternatively, to facilitate the assembly and disassembly of the light source 3, it can be assembled in the receiving groove 24 using methods such as bolt connection, adsorption fixation, and snap-fit. For example, an ear plate with a through hole can be fixedly provided on the light source 3, through which the bolt thread can pass, thereby fixing the ear plate to the side structure 21 with bolts. In some alternative embodiments, a suction cup can be connected to the light source 3, and it can be fixedly connected to the door panel 2 by magnetic attraction or negative pressure adsorption. In some alternative embodiments, the side structure 21 can have a certain elasticity near the receiving groove 24. In this case, by setting the size, for example, before assembly, the receiving groove 24 can be slightly lower than the light source 3, and the light source 3 can be clamped and fixed by the elastic deformation of the receiving groove 24, making assembly convenient.

[0040] In addition, the surface of the light source 3 facing away from the door panel 2 can also be attached to the mounting groove 11, and can be fixed by adhesive or magnetic attraction, which can help improve the fixation of the door panel 2 in the door frame 1.

[0041] Specifically, the mounting groove 11 is a U-shaped groove facing the door panel 2, and the side interlayer 211 is an adaptable U-shaped adhesive layer. The U-shaped adhesive layer wraps around the edge of the door panel body 25 on three sides, so as to achieve comprehensive fixation between the side interlayer 211 and the mounting groove 11 of the door body edge and the door frame 1.

[0042] Furthermore, the peripheral surface 22 of the door panel 2 is located in the edge structure 21, and the receiving groove 24 is opened on the peripheral surface 22 of the door panel 2. The light source 3 emits light into the door panel 2 in a direction perpendicular to the thickness direction of the door panel 2, ensuring that the light can be projected into the interior of the door panel 2.

[0043] Specifically, the U-shaped side interlayer 21 includes a central connecting arm 212 located on one side of the periphery of the door panel body and two end connecting arms 213 located on both sides in the thickness direction of the door panel 2. The receiving groove 24 can be opened on the central connecting arm 212. More specifically, the receiving groove 24 can be opened at the center position of the central connecting arm 212 in the thickness direction to ensure the reliability of the connection.

[0044] Specifically, the receiving groove 24 can be formed on the outer surface of the side interlayer 211 for easy processing. In this case, the side interlayer 211 needs to have a certain degree of light transmittance so that the light emitted by the light source 3 can enter the door panel body through the side interlayer 211. Alternatively, in some embodiments, the receiving groove 24 can penetrate the side interlayer 211 and fit against the surface of the door panel body 25 to ensure that the light from the light source 3 can enter the door panel body 25 and to improve the stability of the installation of the light source 3. In addition, in some embodiments, the light source 3 can also be built into the side interlayer 211. In this case, the space in the side interlayer 211 for installing the light source 3 forms the receiving groove 24.

[0045] Specifically, the receiving groove 24 can be a strip-shaped groove extending perpendicular to the thickness direction, and the light source 3 includes multiple lamp bodies arranged sequentially along the extension direction of the strip-shaped groove. Of course, when the door panel 2 is thick, the multiple light sources 3 can also be arranged sequentially along the thickness direction of the door panel 2.

[0046] Specifically, the periphery 22 of the door panel 2 includes a top surface, a bottom surface, and two side surfaces extending along the height direction. In some embodiments, light sources 3 are provided on the top surface, the bottom surface, and the two side surfaces. In other embodiments, light sources 3 may be provided on only one or two of the side surfaces, and on the side surfaces, the light source 3 is a strip of light, which extends along the height direction of the door panel 2 and is provided on the door panel 2.

[0047] In addition, an installation channel connecting the mounting groove 11 can be provided on the door frame 1. The other end of the installation channel is connected to the outer surface of the door frame 1. The light source 3 can be inspected through the installation channel. At the same time, a removable cover plate can be provided on the installation channel.

[0048] Furthermore, light source 3 is a light strip with multiple lamp bodies to ensure that different prompting or warning functions can be achieved through the cooperation of multiple lamp bodies. The lamp bodies in light source 3 can provide different warning functions through constant illumination, flashing, etc.

[0049] Specifically, the light strip can be an LED light strip, which has the advantages of energy saving and environmental protection. Depending on the needs, LED light strips can be selected, such as monochrome LED light strips, RGB LED light strips, and LED light strips with adjustable color temperature.

[0050] Specifically, the light strip can be equipped with various light bodies that emit different colors of light, such as red, yellow, green, and blue, to meet different prompting or warning functions. The light bodies can be arranged sequentially along the extension direction of the light strip, and multiple light groups can be arranged sequentially along this direction. Each light group can include light bodies of various colors to provide different prompting functions evenly in different locations. Alternatively, each light group can have light bodies of the same color, while adjacent light groups may have light bodies of different colors for ease of assembly.

[0051] Of course, in other embodiments, due to the limitation of installation space, the light source 3 can also be one or more single lamp bodies, and receiving slots 24 can be set at different positions on the edge structure 21 of the door panel 2, with each receiving slot 24 accommodating one lamp body, which makes the setting more flexible.

[0052] Furthermore, to further enhance the prompting or aesthetic functions, a pattern prompting layer is also provided on the surface and / or inside of the door panel 2, and the pattern prompting layer can be displayed under the light of the light source 3.

[0053] Specifically, the door panel 2 has a patterned indication layer on its interior in the thickness direction, specifically disposed on the main body of the door panel. The patterned indication layer forms a predetermined pattern, such as text or Arabic numerals, through methods such as lamination, laser engraving, or printing. Furthermore, the patterned indication layer can be adapted to the light source 3, so that the pattern on the patterned indication layer can be displayed more clearly under the illumination of the light source 3. For example, the patterned indication layer includes a glass light guide plate, on which concave microstructures are formed by laser engraving, which can reveal the pattern under light, giving the door panel 2 an appearance effect of emitting a light pattern.

[0054] Alternatively, in addition to the aforementioned patterned prompt layer, an electronic display screen can be installed on the surface of the main door panel. This screen can be electrically connected to the door controller 4 along with the light source 3, and the door controller 4 can be used for unified opening and closing control.

[0055] Furthermore, the door also includes a door controller 4. The light source 3 is electrically connected to the door controller 4. The door controller 4 is used to control the switching of the light source 3, so that different lamps in the light source 3 can be controlled according to actual needs. Specifically, the switching of each lamp can be controlled to adjust the opening frequency. By controlling the opening frequency, the flashing frequency of the corresponding lamp can be achieved.

[0056] Specifically, the lighting logic of each lamp body of the light source 3 is designed in the door controller 4, which can control the light source 3 to emit different colors or switch states of light in different scenarios, thereby achieving different warning or indication effects such as evacuation, alertness, and normal passage.

[0057] Specifically, in addition to the door controller 4, a control panel, such as a remote control, or a control unit set on the door panel or door frame can be added, so that the corresponding light source 3 can be switched on and off manually as needed, making it more flexible to use.

[0058] Specifically, the door controller 4 is also electrically connected to the power supply unit 43. In this case, the light source 3 can also be electrically connected to the power supply unit 43 through the door controller 4. Of course, in other embodiments, the light source 3 can be a different power source.

[0059] Furthermore, among the multiple lamp bodies of light source 3, two lamp bodies are designated as the first lamp body and the second lamp body. When the door body is in the preset closed position, the door controller 4 controls the first lamp body to turn on and the second lamp body to turn off. When the door body leaves the preset closed position, the door controller 4 controls the first lamp body to turn off and the second lamp body to turn on. At this time, the setting of the first and second lamp bodies can be used to display the open / closed status of the door body.

[0060] It should be noted that the position of the door can be detected by a detection device set at a designated location. Specifically, the door is installed in an electric sliding door, and its door controller 4 has an automatic control mode. In automatic control mode, the door can be automatically opened and closed according to a set opening or closing signal. At this time, the switches of each lamp in the light source 3 can be combined with the door's switch. Of course, the door can also have a manual operation mode.

[0061] Specifically, the door controller 4 is also communicatively connected to the sensing unit 42, for example, a first sensing switch electrically connected to the door controller 4, and / or a second sensing switch wirelessly connected to the door controller 4 via Bluetooth or other means. The first sensing switch can be directly connected to the door body, and the second sensing switch can be set at a certain distance from the door body.

[0062] In some embodiments, the first and second sensing switches are infrared sensing switches, capable of sensing the passage of personnel within a set range of the door body, thereby controlling the opening or closing of the door body via the door controller 4. Specifically, the infrared sensing switch emits infrared rays; when a human body or object enters the sensing area, the reflected infrared light is received by the sensing switch, triggering a corresponding control signal to control the drive motor connected to the door body to operate, opening or closing the door body. Alternatively, the first and / or second sensing switches can also be other photoelectric sensing switches.

[0063] Additionally, it should be noted that when the door is in the preset closed position, both sides of the door body thickness direction can be equipped with a first sensor switch and a second sensor switch, making it a sliding door that can be opened in both directions.

[0064] Furthermore, the light source 3 includes a warning light body. The warning light body is used to turn on and emit warning light after receiving a warning command from the door controller 4. It should be noted that the warning light body can be one of the first light body and the second light body. For example, the warning light body can be the second light body to achieve multi-functional application of the light body and reduce the need for the number of light bodies; or, the warning light body can be a third light body in the light source 3 that is different from the first light body and the second light body.

[0065] It should be noted that the door controller 4 can have a normal state and an emergency state in controlling the light source 3. The emergency state has higher priority than the normal state, so the light source 3 can be controlled with priority according to the needs of the emergency state.

[0066] Under normal conditions, when the door body is in the preset closed position (i.e., after the door body is closed), the door controller 4 controls the first light to turn on and the second light to turn off. At this time, the first light can remain constantly lit. For example, if the first light emits blue light (specifically, ice blue), and the second light emits red light, then the first light emits blue light and remains constantly lit, while the second light is off. When the door body leaves the preset closed position, specifically during the door opening process, during the door closing process, or when the door is paused at the set position, the door controller 4 controls the first light to turn off and the second light to turn on. Specifically, the second light emits red light and remains constantly lit, while the first light is off.

[0067] Based on this, when a pattern prompt layer is set on the main body of the door, the first and second lamps can also illuminate the corresponding pattern prompt layer to display an image after they are turned on.

[0068] In an emergency, the door controller 4 can control the warning lights to provide different alerts based on the received warning signals. The warning signals can be provided by the vehicle control system, which may include monitoring devices that monitor the vehicle's operating environment, such as smoke detection. The warning lights may have only one warning effect; for example, they may flash upon receiving all warning signals, or they may flash, remain constantly lit, or change color depending on the type of warning signal received, such as a fire alarm or emergency braking alarm.

[0069] For example, when the door controller 4 receives the first warning signal, the second lamp acts as a warning lamp, and the controller turns on the second lamp to flash at a set frequency. At this time, the graphic indication layer can also emit a flashing display effect. Alternatively, when the door controller 4 receives the second warning signal, the first, second, and third lamps act as warning lamps and can emit different colors of light. The door controller 4 controls the first, second, and third lamps to alternately switch on and off to achieve a color-changing indication effect.

[0070] In addition, the door controller 4 is electrically connected to the door control unit 41, which includes a manual / electric switch 411, an open-position isolating switch 412, and a closed-position isolating switch 413. By controlling the manual / electric switch 411, the door body can be switched between manual and electric operation.

[0071] In addition to the aforementioned door body, this utility model also provides an electric sliding door, which includes a door body. Specifically, the door body can be the door body provided in any of the above embodiments, and the beneficial effects can be referred to the respective embodiments above. Furthermore, adding lighting pattern effects to the electric sliding door can enhance its aesthetics.

[0072] In addition to the aforementioned door and electric sliding door, this utility model also provides a rail vehicle, which includes a door or an electric sliding door. The door can be any of the door provided in the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0073] Furthermore, the rail vehicle includes a first door and a second door respectively located at both ends of the same carriage, each having a door body. The first door and the second door are electrically connected to a door controller 4. When a preset emergency state is entered, the door controller 4 controls the light source 3 of the first door to emit a preset warning light, and controls the second door to enter a normally open state.

[0074] Specifically, the rail vehicle includes multiple carriages, each with a first door and a second door at both ends. For a selected carriage, a preset emergency state can be set to occur in the carriage adjacent to its first door. For example, if the selected carriage is carriage 3 and the carriage adjacent to the first door of carriage 3 is carriage 2, when the preset emergency occurs in carriage 2, in order to prevent passengers from other carriages from entering carriage 2 through carriage 3, or to instruct personnel to evacuate to carriage 3 and other carriages away from carriage 2, the light source 3 of the first door of carriage 3 emits a preset warning light, such as a flashing red light and a corresponding pattern flashing. At the same time, the first door of carriage 3 can be opened and closed normally to facilitate the passage of crew members, and the second door of carriage 3 away from carriage 2 enters a normally open state to facilitate the rapid evacuation of people in carriage 3 away from carriage 2.
