Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] In the related art, an adjustable high-speed train seat is disclosed, which relates to the technical field of train seats. It includes a seat cushion and a backrest. The bottom of the seat cushion is fixed with a base, the front of the seat cushion is fixed with a connecting plate, a sliding plate is slidably installed on the top of the connecting plate, an armrest is fixed on the side wall of the sliding plate, a limiting mechanism is arranged on the sliding plate, the limiting mechanism includes a slider, the bottom of the slider is fixed with a limiting rod, the bottom of the limiting rod fits with a limiting groove, the limiting groove is opened on the inner wall of the connecting plate, an adjusting mechanism is arranged in the armrest, the top of the slider is fixed with a pull rod, and the top of the pull rod is fixed with a pull ring.

[0030] For this adjustable high-speed train seat, by rotating the knob forward, the threaded rod rotates. Through the cooperation of the moving plate, the transmission rod, and the connecting rod, the two armrests can be moved away from each other, so that people of different body types can use it, making people sit more comfortably. For this adjustable high-speed train seat, by rotating the knob forward, the threaded rod rotates. Through the cooperation of the moving plate, the transmission rod, and the connecting rod, the two armrests can be moved away from each other, so that people of different body types can use it, making people sit more comfortably.

[0031] The adjustable high-speed train seat can be adjusted as follows: Pull the pull ring to move the limit rod out of the limit slot, and then the slide plate can be moved on the connecting plate. When it reaches the specified position, release the pull ring, the pull rod moves downward, driving the slider to move downward, so that the limit rod abuts against the inner wall of the connecting plate. Through left and right fine-tuning, the limit rod is snapped into the limit slot to fix the slide plate, and the position of the armrest can be adjusted, which is more convenient for people to use.

[0032] In the above related technologies, although they have various adjustment functions, there is no support and adjustment function for the necks and waists of adult passengers. At the same time, their sizes are still fixedly set, unable to meet the needs of people with children, unable to adapt to child passengers, and unable to ensure the comfort and safety of child passengers. Therefore, to solve the above problems, the present application provides the following solutions:

[0033] Refer to Figures 1 - 5 , the present invention provides a high-speed train multi-modal adjustment and child safety integrated seat, including a bottom frame 1 installed at the bottom end inside the train carriage. A seat cushion 2 and a backrest 3 are installed on the bottom frame 1, and further includes:

[0034] A support assembly, including a neck support and a waist support. The neck support is arranged at the top of the backrest 3 and is used to adjust and support the neck of the occupant. The waist support is arranged in the middle and lower part of the backrest 3 and is used to adjust and support the waist of the occupant;

[0035] A child support assembly, including a storage member and a child protection member. The storage member is arranged at the bottom end of the bottom frame 1, and the child protection member is stored in the storage member. When a child rides on the seat, the child protection member is installed on the backrest 3 through a limit connecting member and is used to support the child occupant.

[0036] In an embodiment of the present application, in use, for adult occupants, the provided neck support and waist support respectively support the necks and waists of the occupants and can be adjusted according to different passenger needs. For child occupants, the child protection member can be taken out from the storage member and installed on the backrest 3 through a limit connecting member to complete the installation of the child protection member, and it can be adapted to different child occupants after adjustment to ensure their comfort and safety.

[0037] As an optional implementation manner, the neck support includes a neck pillow 4. Cavities 5 are respectively opened at the top of both side walls of the backrest 3. A winding member is arranged in the cavity 5. One end of the winding member extends out of the cavity and is fixedly connected with a first adjustment rope 6.

A top block 20 is fixedly connected to the slider 19, and the top block 20 is in sliding contact with the lumbar support plate 15.

[0044] In an embodiment of the present application, the lumbar support plate 15 is slidably connected to the bracket 16 through the slide rod 17, and it can move back and forth by the limit of the slide rod 17. By setting the bidirectional threaded rod 18 to drive the two sliders 19 to move synchronously, when the sliders 19 move, the lumbar support plate 15 is driven to move by the two top blocks 20.

[0045] As an alternative implementation, the lumbar support plate 15 is of an arc-shaped structure. A guide groove 21 is provided at the rear end of the lumbar support plate 15, and the top block 20 is slidably connected to the guide groove 21.

[0046] In an embodiment of the present application, the lumbar support plate 15 is of an arc-shaped structure to support the waist of the occupant. The guide groove 21 at the rear end is slidably connected to the top block 20, ensuring the stable forward and backward movement of the lumbar support plate 15 when the top block 20 moves.

[0047] As an alternative embodiment, the storage member includes a storage groove 22. A slide rail 23 is installed at the bottom end of the bottom frame 1. The storage groove 22 is slidably connected to the slide rail 23. An electromagnetic lock 24 is provided on the bottom frame 1. The storage groove 22 is connected to the bottom frame 1 in a limited manner through the electromagnetic lock 24. The child protection member is located in the storage groove 22.

[0048] In an embodiment of the present application, the storage groove 22 is slidably connected to the bottom frame 1 through the slide rail 23 and is connected in a limited manner through the electromagnetic lock 24. When in use, the storage groove 22 can be pulled out by unlocking the electromagnetic lock 24, and the child protection member stored inside can be taken out and installed on the backrest 3.

[0049] Specifically, the neck pillow 4 can also be stored in the storage groove 22 when not in use.

[0050] As an alternative embodiment, the child protection member includes a main body frame 25. Both ends of the main body frame 25 are slidably connected with sub-frames 26. A shielding cushion 27 is fixedly connected to the sub-frame 26. The child rider is located between the two shielding cushions 27. A safety belt 28 is installed on the shielding cushion 27.

[0051] In an embodiment of the present application, the main body frame 25 is used to be installed on the backrest 3. By sliding the sub-frame 26 to drive the shielding cushion 27 to move, the distance between the two shielding cushions 27 can be adjusted to adapt to different child passengers, and the safety of the child passengers is further ensured through the safety belt 28.

[0052] As an alternative embodiment, the limit connecting member includes plug-in buckles 29 fixedly connected to both sides of the main body frame 25. Plug-in slots 30 are provided at both ends of the backrest 3. The plug-in buckles 29 are adapted to the plug-in slots 30.

[0053] In an embodiment of the present application, by connecting the plug-in buckles 29 with the plug-in slots 30, the installation of the main body frame 25 on the backrest 3 is realized.

[0054] As an alternative embodiment, a limit head 31 is fixedly connected to the plug-in buckle 29. A limit hole 32 is provided on the inner side wall of the plug-in slot 30. The limit head 31 is adapted to the limit hole 32. A top plate 33 is slidably connected in the plug-in slot 30.
