[0002] With the continuous development of tourism, passenger ships are becoming more and more popular. In passenger ships, the design of cabin doors is crucial to the tourists' experience. In order to facilitate tourists to view the scenery outside the ship, the passenger ship cabin doors are usually designed as sliding doors made of transparent vacuum glass. This not only makes it convenient for tourists to directly view the scenery outside the window through the cabin door, but also increases the tourists' field of vision, effectively improving the tourists' travel experience.

[0003] However, in order to ensure the stability of the sliding door body, the existing sliding doors usually adopt the design of upper and lower sliding rails. Especially when used on passenger ships, the stability of the sliding door body is particularly important. Although this sliding door design ensures the stability of the sliding door body, since the upper and lower ends of the sliding door frame are provided with sliding grooves, for tourists with limited mobility, such as tourists in wheelchairs, when entering and exiting the cabin, the wheels of the wheelchair may be stuck in the sliding grooves of the door frame. For younger tourists, there may be a risk of tripping and injury, and the safety and convenience are relatively low. In view of this, the present invention is specially proposed.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] Example 1:

[0033] Reference Figures 1-11 A barrier-free sliding door for a passenger cabin of a passenger ship includes a door frame 1, a first sliding door 2, and a second sliding door 3. The first sliding door 2 is fixedly installed in the door frame 1, and the second sliding door 3 is slidably connected to the door frame 1. The first sliding door 2 and the second sliding door 3 are parallelly distributed in the door frame 1. The door frame 1 also includes: an upper sliding groove 101 and a lower sliding groove 102 are respectively opened on the upper and lower sides; an upper support rod is equidistantly fixedly connected to the upper end of the second sliding door 3; an upper roller 306 is symmetrically rotated It is dynamically connected to the upper support rod and rolls in the upper slide groove 101; the lower support rod 308 is equidistantly fixedly connected to the lower end of the second sliding door 3; the lower roller 309 is installed at the lower end of the lower support rod 308 through a support and rolls in the lower slide groove 102; a groove 108 is provided in the lower slide groove 102, and the groove 108 is located on the side of the lower end of the door frame 1 away from the first sliding door 2; the barrier-free platform 4 is liftable and arranged on the side of the lower slide groove 102 close to the groove 108.

[0034] When the barrier-free sliding door is put into use on a passenger ship, the staff first fixes the door frame 1 with the first sliding door 2 fixedly installed at the entrance and exit of the passenger cabin, and ensures that the door frame 1 is installed firmly and horizontally, and then the second sliding door 3 can be installed, so that the upper roller 306 and the lower roller 309 are respectively located in the upper slide groove 101 and the lower slide groove 102, and the position of the second sliding door 3 is adjusted so that the second sliding door 3 can be smoothly moved in the door frame 1 with the cooperation of the upper roller 306 and the lower roller 309. Slide, then the barrier-free platform 4 can be installed to the position near the groove 108 in the lower sliding groove 102, and finally the sliding door can be debugged to check whether the opening and closing of the second sliding door 3 are smooth, whether the lifting of the barrier-free platform 4 is normal, and when the barrier-free platform 4 moves down to the lowest end, whether the upper surface is flush with the lower end surface inside the lower sliding groove 102, and when the barrier-free platform 4 moves up to the highest end, whether the upper surface is flush with the upper surface of the lower sliding groove 102. After all debugging is completed and qualified, it can be put into use.

[0035] When it is necessary to close the entrance and exit of the passenger cabin, the barrier-free platform 4 is first controlled to descend to the lowest position, and then the user can pull the second sliding door 3 to close the entrance and exit of the passenger cabin. When it is necessary to open the entrance and exit of the passenger cabin, the barrier-free platform 4 is first controlled to move up to the highest position to hide the lower slide groove 102, and then the user pulls the second sliding door 3 to open the entrance and exit of the passenger cabin, and then tourists with limited mobility, younger tourists and crew members transporting goods can pass through the sliding door more conveniently.

[0036] Example 2:

[0037] Reference Figures 1-11 , a barrier-free sliding door for a passenger ship cabin is basically the same as Example 1, and further, a first magnetic plate 105 and a second magnetic plate 106 are respectively installed on the inner walls on both sides of the door frame 1, and two third magnetic plates 303 are symmetrically arranged on both sides of the second sliding door 3. The two third magnetic plates 303 are magnetically attracted to the first magnetic plate 105 and the second magnetic plate 106 on the same side, and the first magnetic plate 105, the second magnetic plate 106 and the third magnetic plate 303 are on the same horizontal line.

[0038] Through the mutual cooperation of the first magnetic plate 105, the second magnetic plate 106 and the third magnetic plate 303, when the second sliding door 3 is opened or closed, the second sliding door 3 can be firmly in an open or closed state under the action of the mutual magnetic attraction between the third magnetic plate 303 and the first magnetic plate 105 and the second magnetic plate 106, thereby preventing the second sliding door 3 from moving left and right when the hull shakes, thereby effectively improving the stability of the second sliding door 3.

[0039] Example 3:

[0040] Reference Figures 1-11 , a barrier-free sliding door for a passenger ship cabin, is basically the same as Example 2. Furthermore, third slots 301 are symmetrically opened on both sides of the second sliding door 3, and two third magnetic plates 303 slide in the third slots 301 on the same side respectively.

[0041] The second sliding door 3 is symmetrically provided with fourth slots 302 on the side away from the first sliding door 2, and the two fourth slots 302 are respectively connected to the third slots 301 on the same side. A first handle 304 is provided on the side of the second sliding door 3 close to the fourth slot 302, and both ends of the first handle 304 extend into the third slot 301 on the same side, and are fixedly connected to the third magnetic plate 303 on the same side. A fifth slot 3021 connected to the third slot 301 is provided on the side of the second sliding door 3 away from the first handle 304, and the fifth slot 3021 is provided on the side close to the barrier-free platform 4. A second handle 305 is provided at the fifth slot 3021, and one end of the second handle 305 extends into the third slot 301 and is fixedly connected to the third magnetic plate 303 on the same side.

[0042] When the second sliding door 3 needs to be closed, the visitor first pulls the third magnetic plate 303 to the side away from the first magnetic plate 105 through the first handle 304 or the second handle 305 to separate the third magnetic plate 303 from the first magnetic plate 105. Then, the visitor can continue to push the second sliding door 3 through the first handle 304 or the second handle 305 until the third magnetic plate 303 away from the first magnetic plate 105 is magnetically attached to the second magnetic plate 106, thereby completing the closing of the second sliding door 3.

[0043] When the second sliding door 3 needs to be opened, the visitor first pulls the third magnetic plate 303 to the side away from the second magnetic plate 106 through the first handle 304 or the second handle 305 to separate the third magnetic plate 303 from the second magnetic plate 106, and then continues to push the second sliding door 3 through the first handle 304 or the second handle 305 until the third magnetic plate 303 away from the second magnetic plate 106 is magnetically attached to the first magnetic plate 105, and the second sliding door 3 can be opened.

[0044] It should be noted that if the third magnetic plate 303 is not separated from the first magnetic plate 105 or the second magnetic plate 106 first, tourists will need to overcome the magnetic attraction between the magnetic plates and the weight of the second sliding door 3 itself in order to open the second sliding door 3 when pushing and pulling the second sliding door 3. By dividing the closing or opening of the second sliding door 3 into two steps, the first time only requires overcoming the magnetic attraction between the magnetic plates, and the second time only requires overcoming the gravity of the second sliding door 3. By decomposing the resistance, the force required to push and pull the second sliding door 3 at the beginning can be effectively reduced, and the force required for tourists to open and close the second sliding door 3 can be effectively reduced, providing convenience for tourists with less strength.

[0045] Example 4:

[0046] Reference Figures 1-11 , a barrier-free sliding door for a passenger ship cabin is basically the same as Example 3, and further, a first slot 103 is opened in the door frame 1 near the first magnetic plate 105, and the first magnetic plate 105 is slidably connected to the first slot 103, and the lower end of the inner part of the groove 108 is slidably connected to a right-angled trapezoidal block 109, and the lower end of the barrier-free platform 4 is symmetrically fixedly connected to two inverted right-angled trapezoidal blocks 408 used in conjunction with the right-angled trapezoidal block 109, and a fixing plate is fixedly connected to the side of the groove 108 away from the inclined surface of the right-angled trapezoidal block 109, and a first tension spring 1010 is fixedly connected between the fixing plate and the right-angled trapezoidal block 109, and a pull rope 107 is fixedly connected between the first magnetic plate 105 and the right-angled trapezoidal block 109, and a channel for use with the pull rope 107 is opened in the door frame 1.

[0047] When it is necessary to lower the barrier-free platform 4 in order to close the second sliding door 3, the visitor first pulls the third magnetic plate 303 through the first handle 304 or the second handle 305. At this time, the third magnetic plate 303 and the first magnetic plate 105 will be separated, and then the right-angled trapezoidal block 109 will move toward one side of the fixed plate under the tension of the first tension spring 1010. When the right-angled trapezoidal block 109 is attached to the inclined surface of the inverted right-angled trapezoidal block 408, the barrier-free platform 4 will gradually move downward. When the inverted right-angled trapezoidal block 408 moves to the bottom, the upper surface of the barrier-free platform 4 will be flush with the bottom surface of the sliding groove 102. Then, the second sliding door 3 is pulled to make the lower roller 309 roll onto the barrier-free platform 4. When the other third magnetic plate 303 of the second sliding door 3 is magnetically attached to the second magnetic plate 106, the closing operation of the second sliding door 3 can be completed.

[0048] When the second sliding door 3 needs to be opened, the visitor first pulls the third magnetic plate 303 in the opposite direction through the first handle 304 or the second handle 305 to separate the third magnetic plate 303 from the second magnetic plate 106, and then continues to push the second sliding door 3. When the second sliding door 3 is fully opened, the third magnetic plate 303 away from the second magnetic plate 106 will generate a magnetic attraction on the first magnetic plate 105, and then the first magnetic plate 105 will move to the side of the third magnetic plate 303, and the first magnetic plate 105 will be pulled out through the pull rope 106. By pulling the right-angled trapezoidal block 109, the right-angled trapezoidal block 109 will overcome the tension of the first tension spring 1010 and push the inverted right-angled trapezoidal block 408 upward through the inclined surface. When the upper plane of the right-angled trapezoidal block 109 is in contact with the lower plane of the inverted right-angled trapezoidal block 408, the barrier-free platform 4 will move up to the upper end and be flush with the upper surface of the lower slide chute 102, thereby blocking the lower slide chute 102. At this time, tourists can enter and exit the cabin more safely, which provides greater convenience for tourists in wheelchairs.

[0049] Example 5:

[0050] Reference Figures 1-11 , a barrier-free sliding door for a passenger ship cabin is basically the same as Example 4, and further includes a tensioning spring 3010, a lower support rod 308 as a telescopic guide rod, and the tensioning spring 3010 is sleeved on the outer side of the lower support rod 308. The two ends of the tensioning spring 3010 are respectively connected to the second sliding door 3 and the support. An installation groove is provided on the upper surface of the barrier-free platform 4, and a rotating plate 405 is rotatably connected to the installation groove through a rotating shaft. The rotating shaft is provided on the side close to the lower roller 309, and a through groove 407 connected to the installation groove is provided at the lower end of the side of the barrier-free platform 4 away from the rotating shaft. A multi-section electric telescopic rod 1011 is fixedly connected to the groove 108 below the through groove 407.

[0051] A second slot 104 is provided in the door frame 1 near the second magnetic plate 106, and the second magnetic plate 106 is slidably connected in the second slot 104. A second tension spring 1012 is symmetrically fixedly connected to the slot wall away from the opening in the second slot 104, and one end of the second tension spring 1012 near the slot is fixedly connected to the second magnetic plate 106. The second slot 104 is located between the two second tension springs 1012 and is fixedly connected to a first pressure sensor 1013. A second pressure sensor 406 is embedded in the side of the rotating plate 405 near the rotating shaft.

[0052] The first pressure sensor 1013 , the second pressure sensor 406 and the multi-section electric telescopic rod 1011 are all electrically connected to an external main controller.

[0053] When the second sliding door 3 needs to be opened, the visitor first separates the third magnetic plate 303 from the second magnetic plate 106 through the first handle 304 or the second handle 305, and then the second magnetic plate 106 moves toward the side of the first pressure sensor 1013 under the tension of the second tension spring 1012. When the second magnetic plate 106 applies pressure to the first pressure sensor 1013, the first pressure sensor 1013 transmits a signal to the main controller, and then the main controller controls the multi-section electric telescopic rod 1011 to extend, and then the telescopic end of the multi-section electric telescopic rod 1011 passes through the through slot 40. 7 is against the rotating plate 405, and then the rotating plate 405 will rotate upward under the pushing of the multi-section electric telescopic rod 1011 to overcome the tensioning force of the tensioning spring 3010. At this time, the rotating plate 405 will be in an inclined state, and then the tensioning spring 3010 will generate an oblique upward force on the second sliding door 3 under the action of the inclined surface of the rotating plate 405. Then, when the tourist pulls the second sliding door 3 through the first handle 304 or the second handle 305, the force required will be reduced, further reducing the force required for the tourist to open the second sliding door 3, providing convenience for tourists with less strength.

[0054] When the lower roller 309 rolls on the inclined rotating plate 405, each lower roller 309 will apply a pressure to it after passing through the second pressure sensor 406. When it is put into use, the number of lower rollers 309 can be input into the controller. When the controller detects that all the lower rollers 309 apply pressure to the second pressure sensor 406, the controller can control the multi-section electric telescopic rod 1011 to retract and return to its position, and then the rotating plate 405 will rotate downward to the installation slot of the barrier-free platform 4 under the action of its own gravity, so that when the second sliding door 3 is closed again later, the second sliding door 3 can be easily moved to the barrier-free platform 4.

[0055] It should be noted that the first pressure sensor 1013, the second pressure sensor 406, the multi-section electric telescopic rod 1011, and the main controller can be powered by a separate power supply, and a backup power supply is provided so that the sliding door can be used normally in the event of a circuit failure or power outage.

[0056] Example 6:

[0057] Reference Figures 1-11 , a barrier-free sliding door for a passenger ship cabin is basically the same as Example 5. Furthermore, a first T-block 403 is symmetrically fixedly connected to one side of the barrier-free platform 4, and a first T-shaped slide groove used in conjunction with the first T-block 403 is opened on the groove wall of the lower slide groove 102. Through the cooperation of the first T-block 403 and the first T-shaped slide groove, the barrier-free platform 4 can be limited without affecting the lifting and lowering of the barrier-free platform 4, thereby effectively ensuring the stability of the lifting and lowering of the barrier-free platform 4.

[0058] like Figure 6 、 Figure 7 As shown, a mounting plate 401 is installed at the lower end of the door frame 1 near the barrier-free platform 4, and a second T-block 404 is symmetrically fixedly connected to one side of the barrier-free platform 4 near the mounting plate 401. A second T-shaped slide groove is provided on the mounting plate 401 for use with the second T-block 404. By using the mounting plate 401, the second T-block 404 and the second T-shaped slide groove in combination, not only can the internal components of the groove 108 be hidden, thereby improving the aesthetics of the sliding door, but also the stability of the barrier-free platform 4 can be further improved.

[0059] like Figure 1 As shown, a lap plate 402 is rotatably connected to the side of the mounting plate 401 away from the barrier-free platform 4. After the sliding door is installed at the entrance and exit of the passenger cabin of the passenger ship, the end of the lap plate 402 away from the mounting plate 401 can be overlapped on the floor outside the passenger cabin of the passenger ship, so that no matter how much the outer floor is lower than the threshold of the door frame 1, it can pass smoothly through the sliding door, thereby further reducing the inconvenience caused by the passage in and out.

[0060] It should be noted that since the wheels of a wheelchair or cart will roll over the lap plate 402 when entering and exiting the cabin, when the lap plate 402 is tilted, the contact area between the lap plate 402 and the ground outside the sliding door will be reduced. Therefore, when there are decorative items such as flooring on the ground, it may cause damage to them. In view of this, when actually using the sliding door, refer to Figure 12 As shown, a triangular support block can be integrally formed at the bottom of the lap plate 402 so that the lower surface of the lap plate 402 can contact the floor, increasing the contact area between the lap plate 402 and the floor, thereby reducing damage to decorative objects such as the floor, and soft materials such as rubber strips can also be set at the position where the lap plate 402 contacts the floor, so that the lap plate 402 can be in flexible contact with the floor, thereby reducing damage to the floor.

[0061] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
