[0002] For business class seats and first-class seats on high-speed trains, there are inevitably gaps between the seat cushion and the armrests on both sides. If a mobile phone is accidentally dropped through the gap and falls to the bottom of the seat, the phone battery may be caught and crushed by the seat movement mechanism (the transmission component that adjusts the seat angle and fore-aft position), which may cause a fire or even an explosion.

[0003] Currently, there is no specific, structurally compatible, and highly reliable protective solution for the problem of items falling out of such seat gaps. Therefore, there is an urgent need for a structural design that can effectively seal the gaps and prevent items from falling out in order to eliminate the aforementioned safety hazards.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-6 To address the problems mentioned in the background section, this utility model provides a high-speed rail business class seat anti-fall follow-up structure to solve the above technical problems. The technical solution is as follows:

[0026] A high-speed rail business seat anti-fall follow-up structure includes: sealing plate one 110, hinge 120 and sealing plate two 130;

[0027] One end of the hinge 120 is fixedly connected to the second sealing plate 130, and the other end of the hinge 120 is slidably connected to the first sealing plate 110.

[0028] A gap baffle 132 is fixedly attached to the inner side of the second sealing plate 130. The gap baffle 132 extends along the length of the second sealing plate 130. The inner side of the second sealing plate 130 refers to the side close to the seat cushion 210.

[0029] Under the drive of external force, the overall structure formed by the hinge 120 and the second sealing plate 130 can slide relative to the first sealing plate 110.

[0030] Sealing plate 110 serves as the rotating base component of the device, hinged to the backrest frame 240 of the seat, and can rotate around the hinge axis as the posture of the backrest changes. Sealing plate 110 works in conjunction with sealing plate 230 to form a barrier, directly preventing objects from falling through the gap 230, while also providing a sliding support surface for the hinge, making it a key component of dynamic sealing.

[0031] Seat plate 2 130 is a linkage component that moves synchronously with seat cushion 210. It is fixed to the seat plate below seat cushion 210 and connected to seat plate 1 110 via hinge 120. The structure of seat plate 2 130, together with gap baffle 132, forms a dynamic seal for gap 230, ensuring that the seat always covers the gap area in different postures.

[0032] The hinge 120 is the core linkage structure connecting the first sealing plate 110 and the second sealing plate 130. The hinge 120 is a hinge, with the first leaf fixed to the second sealing plate 130 and the second leaf slidably connected to the first sealing plate 110. This allows for both relative rotation and relative sliding along the length direction, ensuring coordinated and unobstructed movement of the two when adjusting the seat.

[0033] The gap baffle 132 is located inside the sealing plate 210 and extends along the length direction. When it is assembled, it will go deep into the seat cushion and can directly block the gap between the seat cushion 210 and the inner side of the armrest 220, preventing objects such as mobile phones from sliding into the bottom of the seat from the inside of the seat cushion.

[0034] In this embodiment, the hinge 120 is a hinge; the first leaf of the hinge is fixed to the second sealing plate 130; the second leaf of the hinge is slidably connected to the first sealing plate 110.

[0035] In this embodiment, a waist hole 111 is provided on the sealing plate 110 along its length direction; a bolt is fixed on the second leaf of the hinge; the bolt slides through the waist hole 111.

[0036] In this embodiment, an anti-detachment component 121 is fixedly connected to the tail of the bolt; the anti-detachment component 121 is either a nut screwed to the tail of the bolt or a baffle welded to the tail of the bolt. This structural design achieves both a sliding connection between the hinge and the sealing plate 110 and prevents components from falling off, ensuring structural stability.

[0037] In this embodiment, baffles 112 are fixedly connected to both sides of the sealing plate 110 along its length. The baffles 112 can prevent dust and debris from entering the gap between the sealing plate 110 and the seat back, avoiding impurities from affecting the flexibility of the mechanism and extending the service life of the device.

[0038] In this embodiment, a retaining edge 131 is fixedly attached to the outer side of the sealing plate 130. The retaining edge 131 prevents external dust from entering the connection area between the sealing plate 130 and the seat cushion and armrest, and protects the connection structure of the hinge and bolts.

[0039] In this embodiment, the sealing plate 2 130 is provided with a waist hole 2 133; a bolt 2 is fixed on the first leaf of the hinge, the bolt 2 passes through the waist hole 2 133 and is locked with a nut at its end. The design of the waist hole 2 133 allows for fine adjustment of the hinge position, which is convenient for calibrating the component angle during assembly and adapting to the installation tolerances of different seats.

[0040] In this embodiment, an anti-detachment bending edge 134 is fixedly attached to the top of the gap baffle 132. When this utility model is later assembled on a seat, the anti-detachment bending edge 134 can be hung on the seat cushion frame 250 to achieve auxiliary fixation and enhance the connection stability between the device and the seat.

[0041] The working process of the anti-fall-off follow-up structure for a high-speed rail business seat provided in this embodiment is as follows:

[0042] (1) The present invention is installed in the gap between the seat cushion and the side armrest; the sealing plate one is hinged to the backrest frame of the seat and maintains the initial angle; the sealing plate two is fixed on the seat plate under the seat cushion and connected to the sealing plate one by a hinge; at this time, the sealing plate one, the sealing plate two and the gap baffle together cover the gap, and the anti-detachment bending edge is hung on the seat cushion frame for auxiliary fixation, forming a complete protective barrier.

[0043] (2) When the seat is adjusted, the seat cushion moves with the seat movement mechanism (such as from sitting to lying down), and the second sealing plate moves forward with the seat cushion in sync; the first sealing plate rotates around the hinge axis with the seat back frame to adapt to the change of backrest angle; the second leaf of the hinge slides along the waist hole of the first sealing plate through the bolt, realizing the relative displacement of the first sealing plate and the second sealing plate, ensuring that the two do not separate or get stuck during movement.

[0044] (3) Regardless of whether the seat is in a sitting or reclining position, the first and second sealing plates always cover the gaps through linkage, and the gap baffle extends into the inside of the seat cushion to seal the dead corners; if objects such as mobile phones fall, they will be intercepted by the sealing plates or gap baffles, and the anti-slip bending edge further prevents the objects from slipping and completely avoids them from falling into the bottom of the seat and contacting the motion mechanism.

[0045] The present invention provides a high-speed rail business seat anti-fall follow-up structure with the following advantages: the present invention can completely seal the gap between the seat cushion and the armrest during the seat adjustment process, effectively preventing items from falling to the bottom of the seat and completely eliminating safety hazards; the present invention can adapt to different seat postures, provides comprehensive protection and strong reliability, and has the characteristics of simple structure and convenient installation, requiring no additional power support and having low cost.
