Description

Technical Field

[0001] This invention relates to the field of transportation vehicle seating technology, and more specifically to a table support for the backrest table of a rail transit seat. Background Technology

[0002] With the increasing popularity of high-speed rail and airplanes, the use of tray tables on these rail transit systems is gradually increasing. However, in actual use, there are always some unsanitary public areas where the tray tables can accumulate bacteria and fungi, leading to infection. Current common disinfection methods typically involve disinfection after the train or airplane stops, but this method cannot be universally applied in real time, potentially causing cross-infection among passengers getting on and off. Furthermore, the existing tray tables on high-speed rail and airplanes have low load-bearing capacity. A method similar to the one described in patent number CN202010129223.3 for use on trains... A table support for the backrest of a car or aircraft seat includes an upper support and a lower support. One end of the lower support is hinged to a seat mounting arm for mounting the seat, and the other end is connected to one end of the upper support. The other end of the upper support is hinged to the table. A rotating buckle is provided on the back of the seat, which limits the table to a position so that the table and seat move synchronously. The seat is slidably connected to the seat mounting arm, and the seat swings back and forth around a certain point. A retractable compensation mechanism is provided at the connection between the upper and lower supports. When the table is limited by the rotating buckle, the compensation mechanism activates when the seat swings to prevent the table from disengaging from the rotating buckle. This invention achieves the retraction and extension of the table support through the sliding of the upper and lower supports to meet the retraction and extension requirements when the seat moves. The included locking mechanism ensures the stability of the table support and meets the needs of table use. However, this device cannot perform real-time table disinfection, and the load-bearing capacity of the backrest table is relatively low. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this application, it should be understood that the terms "middle," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] Example 1:

[0037] like Figure 1 and Figure 2 As shown, a table support for the back table of a rail transit seat includes a seat, which is fixed on a fixed base 1. Two support limiting platforms 4 are fixed at both ends of the fixed base 1. A table support 5 is hinged to the support limiting platform 4 through a short shaft. A table 6 is hinged on the table support 5. A periodic disinfection device 7 is provided in the rear end of the seat for periodically disinfecting the surface of the recycled table 6.

[0038] The working principle and beneficial effects of this embodiment are as follows: By fixing the seat to the fixed base 1, it provides height support and fixation. By fixing two bracket limiting platforms 4 at both ends of the fixed base 1, the bracket limiting platforms 4 can be hinged via a short axis, which facilitates the use of the table support 5, and facilitates the unfolding and use of the rear table 6, making it convenient for customers on the back seat to use the table. At the same time, it is convenient to retract the table to prevent affecting the use of space. By setting a periodic disinfection device 7 in the rear of the seat to periodically disinfect the surface of the recycled table 6, the disinfection is controlled to ensure that each customer who has used the table is disinfected in real time after leaving the so-called retracted table 6. This prevents the gap caused by the alternating use of time and space due to centralized disinfection, which may lead to unnecessary alternating infection of bacteria and fungi on the table. This effectively solves the problem that with the increasing alternating use of back tables on high-speed rail and airplanes, there are always some unhygienic public places where bacteria and fungi can accumulate on the surface of the back table, which may cause alternating infection of customers after getting on and off the train.

[0039] Example 2:

[0040] like Figure 1 — Figure 14 As shown, a table support for the backrest table of a rail transit seat is provided. The inner wall of the support limiting platform 4 is provided with an inclined slope to limit the inclination of the table support 5. A central horizontal support rod 22 for stable support is fixed between two symmetrically arranged table supports 5. The upper end of the table support 5 is hinged to the table 6 through a hinge shaft 26. The upper end of the table support 5 is provided with a limiting groove 23. A limiting sliding shaft 27 is limited and slidable in the limiting groove 23 and fixed on the table 6.

[0041] The working principle and beneficial effects of this embodiment are as follows: by providing an inclined slope on the inner wall of the bracket limiting platform 4, the tilting effect can be achieved when the tilting angle of the tabletop bracket 5 is limited, preventing the two symmetrically arranged tabletop brackets 5 from tilting too much and exceeding the reasonable use range of the tabletop 6.

[0042] By fixing a central horizontal support rod 22 between two symmetrically arranged tabletop supports 5, the tilting of the two tabletop supports 5 is further limited, which has the effect of providing stable support, thereby making the tabletop 6 more stable to use and providing further support.

[0043] The tabletop 6 is hinged to the upper end of the tabletop support 5 via a hinge shaft 26. A limiting groove 23 is provided at the upper end of the tabletop support 5, and a limiting shaft 27 is limited and slidable within the limiting groove 23. The limiting shaft 27 is fixed on the tabletop 6, thereby providing a limiting and supporting function when the tabletop 6 is laid out and used, while ensuring the horizontal use of the tabletop 6.

[0044] Example 3:

[0045] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided, wherein the central horizontal support rod 22 is symmetrically provided with extension support hinge rods 24 by means of a short shaft hinge; the upper end of the extension support hinge rod 24 is hinged to the lower end of the table 6 by means of a short shaft, the upper end of the extension support hinge rod 24 is sloping, and the sloping surface of the upper end of the extension support hinge rod 24 is in contact with the lower end of the table 6.

[0046] The working principle and beneficial effects of this embodiment are as follows: By symmetrically setting an extension support hinge rod 24 on the central horizontal support rod 22 through a short axis hinge, the extension support hinge rod 24 is hinged to the lower end of the table board 6 through a short axis, which further supports the end of the table board 6 that is close to the person's use, thereby ensuring that the support load-bearing capacity of the table board 6 is improved, and it is convenient to place easily portable items on the table board 6 in the usage scenario.

[0047] By extending the upper end of the hinge rod 24 to a slope, the slope of the upper end of the hinge rod 24 is aligned with the lower end of the tabletop 6, ensuring that the horizontal tabletop 6 is also supported by the hinge rod 24. This, together with the two tabletop supports 5, provides support and prevents the tabletop 6 from tilting due to excessive weight. This further addresses the issue of the low load-bearing capacity of the back tabletop.

[0048] Example 4:

[0049] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided. A folding anti-pinch plate 25 is fixed on the extended support hinge rod 24. The folding anti-pinch plate 25 is fixed in the table lower groove 29 at the lower end of the table 6. The folding anti-pinch plate 25 is set in a folded and retracted state.

[0050] The working principle and beneficial effects of this embodiment are as follows: A folding anti-pinch plate 25 is fixed on the extended support hinge rod 24. The material of the folding anti-pinch plate 25 is selected to have partial elasticity. By fixing the folding anti-pinch plate 25 in the tabletop groove 29 at the lower end of the tabletop 6, the folding anti-pinch plate 25 is set in a folded and retracted state. In order to facilitate the flat unfolding of the extended support hinge rod 24 at the angle during the retraction and unfolding process of the tabletop 6, it prevents unnecessary use damage caused by the retracted angle. Especially in the scenario of public transportation use, it further provides stable support while preventing unnecessary angle damage caused by the extended support hinge rod 24; thus playing a protective role in use.

[0051] Example 5:

[0052] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided. The upper end of the table 6 is provided with a lifting support plate 28. The lower end of the lifting support plate 28 is hinged to the table 6 via a short shaft. The upper end of the lifting support plate 28 is hinged to a hinged threaded cylinder 31 via a short shaft. The lifting and rotating screw 30 is connected to the hinged threaded cylinder 31 via a threaded connection. The lifting and rotating screw 30 is rotatably connected to the lower end of the table 6. The lifting and rotating screw 30 is provided with a convenient rotating head.

[0053] The working principle and beneficial effects of this embodiment are as follows: By providing a lifting support plate 28 on the upper surface of the tabletop 6, in order to facilitate some passengers to read books or use laptops on the tabletop 6, by rotating the lower lifting screw 30, the upper end of the lifting support plate 28 is raised by the hinged threaded cylinder 31. At the same time, the lower end of the lifting support plate 28 is restrained by the short shaft hinge fastened to the tabletop 6, thereby allowing the lifting support plate 28 to tilt at an angle, which facilitates the use of books and laptops. The lifting screw 30 is provided with a convenient rotating head for easy position finding and rotation.

[0054] Example 6:

[0055] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided, wherein the lower end of the end face of the lifting support plate 28 is hinged and fastened with a support base.

[0056] The working principle and beneficial effects of this embodiment are as follows: a support base is hinged and fastened to the lower end of the end face of the lifting support plate 28, so that when the lifting support plate 28 is used, the fastened support base can support the books and laptops, thereby facilitating office work at an inclined angle during transportation.

[0057] Example 7:

[0058] like Figure 1 — Figure 14 As shown, a table support for the backrest table of a rail transit seat is disclosed. The seat includes a seat base 2 and a seat back 3. The seat base 2 is fixed on a fixed base 1. The lower end of the seat back 3 is hinged to the seat base 2 via a locking transmission. The rear end of the seat back 3 is provided with a rotating locking rod 9 and a table and chair recycling slot 8. A periodic sterilizer 7 is provided in the table and chair recycling slot 8. The rotating locking rod 9 is rotatably connected to the seat back 3 for locking and snapping the retracted table 6.

[0059] The working principle and beneficial effects of this embodiment are as follows: By using existing technology and products actually used in transportation tools such as high-speed rail, the lower end of the seat back 3 is hinged to the seat base 2 through locking transmission. The seat back 3 can be conveniently tilted and used on the seat base 2 by air pressure, hydraulic pressure or transmission control.

[0060] A rotating locking rod 9 and a table and chair recycling slot 8 are provided at the rear end of the seat back 3. A periodic sterilizer 7 is provided in the table and chair recycling slot 8. The rotating locking rod 9 is rotatably connected to the seat back 3 to lock and fasten the retracted table 6. The table 6 can be easily locked and released by manually using the rotating locking rod 9.

[0061] Example 8:

[0062] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided. The periodic sterilizer 7 includes a slide rail control motor 10, which is fixed to one side of the table and chair recycling tank 8. The slide rail control motor 10 drives a threaded shaft slide rail 11 to rotate longitudinally and is connected to the table and chair recycling tank 8. The threaded shaft slide rail 11 is connected to one end of a sterilization table 12 by a threaded engagement. The other end of the sterilization table 12 is connected to and fixed to a limiting slide 14, which slides longitudinally to limit the movement on the other side of the table and chair recycling tank 8.

[0063] The working principle and beneficial effects of this embodiment are as follows: By controlling the use of the drive slide rail control motor 10, and then fixing the slide rail control motor 10 to one side of the table and chair recycling tank 8, the slide rail control motor 10 drives the threaded shaft slide rail 11 to rotate longitudinally and connect to the table and chair recycling tank 8. Because the threaded shaft slide rail 11 is connected to one end of the disinfection table 12 through threaded engagement, and the other end of the disinfection table 12 is connected to and fixed to the limiting slide 14, the limiting slide 14 slides longitudinally to the other side of the table and chair recycling tank 8, thereby realizing the up and down sliding of the disinfection table 12 in the table and chair recycling tank 8, thereby realizing the disinfection of the end face of the recycled table board 6.

[0064] Example 9:

[0065] like Figure 1 — Figure 14 As shown, a table support for the back table of a rail transit seat is provided. The disinfection table 12 is provided with a plurality of disinfection nozzles 13 evenly arranged. The plurality of disinfection nozzles 13 are all connected to a limiting slide 14 through an electrically controlled valve pipe. The electrically controlled valve pipe is fixed inside the disinfection table 12. A sealing sliding sleeve 15 is connected to and fixed on the limiting slide 14. An internal pressure disinfectant bottle 16 is fastened and sealed on the sealing sliding sleeve 15.

[0066] The working principle and beneficial effects of this embodiment are as follows: by replacing the internal pressure disinfectant bottle 16 on the sealing sliding sleeve tube 15, the internal pressure disinfectant bottle 16 drives the disinfectant through the sealing sliding sleeve tube 15 and the limiting slide seat 14 under the control of the electrically controlled valve pipeline to flow into the disinfection table 12, and then flows out in a spray form through multiple disinfection nozzles 13, thereby cooperating with the up-and-down sliding disinfection table 12 to disinfect the end face of the table 6.

[0067] Example 10:

[0068] like Figure 1 — Figure 14 As shown, a table support for the backrest table of a rail transit seat is provided. The sealing sliding sleeve 15 includes a sealing socket platform 18, an outer sleeve 19, an inner sliding sleeve 20, and an inner fixing sleeve 21. The outer sleeve 19 is fixed and connected to the limiting slide seat 14. Multiple inner sliding sleeves 20 are sealed and slidably connected between the outer sleeve 19 and the inner fixing sleeve 21. The upper end of the inner fixing sleeve 21 is fixed to the seat back 3. The sealing socket platform 18 is fixed on the inner fixing sleeve 21. Multiple sealing insertion rings are provided on the sealing socket platform 18. Multiple elastic buckles are provided inside the sealing insertion rings. The multiple sealing insertion rings of the sealing socket platform 18 are inserted into the internal pressure disinfectant bottle 16 and locked by the multiple elastic buckles.

[0069] The working principle and beneficial effects of this embodiment are as follows: the use of the sealing sliding sleeve 15 is adapted to the continuously sliding and extending limiting slide 14 to ensure the stable addition of disinfectant; the outer sleeve 19 is fixed and connected to the limiting slide 14, and multiple inner sliding sleeves 20 are sealed and slidably connected between the outer sleeve 19 and the inner fixed sleeve 21. The upper end of the inner fixed sleeve 21 is fixed to the seat back 3, so as to prevent interference during the conveying process while carrying out sealed conveying.

Multiple elastic buckles are provided inside the sealing insertion rings. The internal pressure disinfectant bottle 16 is inserted into the multiple sealing insertion rings of the sealing socket platform 18 and locked by the multiple elastic buckles, which facilitates the replacement and use of the internal pressure disinfectant bottle 16. The sealing and locking is provided by the sealing baffle 17 provided in the seat back 3 to effectively ensure the use of the internal pressure disinfectant bottle 16 in the environment. The sealing baffle 17 is provided in the seat back 3 to seal the end face and prevent the internal pressure disinfectant bottle 16 from being stolen and replaced in public places.

[0071] Example 11:

[0072] like Figure 1 — Figure 14As shown, a table support for the backrest table of a rail transit seat is provided. A light sensor is installed in the table and chair recycling slot 8, corresponding to a designated position on the table 6. The sensor is connected to the slide rail control motor 10 and the electrically controlled valve pipeline through a program setting. Then, three minutes after the table 6 is retracted, the automatic program is activated, so that the slide rail control motor 10 and the electrically controlled valve pipeline can be opened simultaneously for disinfection. After one cycle is completed, the program stops automatically and waits for the next program cycle to perform automatic disinfection again, making it suitable for disinfection of table 6 in public environments.
