Abstract
Description
Technical Field
[0001] This invention relates to the field of passenger ship seat technology, and in particular to a passenger ship seat designed to prevent seasickness. Background Technology
[0002] Passenger ship seats are seating facilities specifically designed for waterborne passenger transport. They are typically made of waterproof and corrosion-resistant materials, and feature ergonomic support, adjustable backrests, seat belts, and interfaces for life-saving equipment to meet passenger comfort, navigation safety, and maritime regulations.
[0003] Seats are an indispensable part of passenger ships. However, most passenger ship seats on the market are currently welded to the ship and cannot be moved or tilted. Therefore, when the passenger ship is rocked or tilted, the seats will rock and tilt along with the ship, which will exacerbate passengers' seasickness. Existing seats cannot keep passengers level when the ship tilts, and the means to prevent passengers from getting seasick are limited. When the ship moves and shakes, it will cause passengers to feel uncomfortable. Therefore, this application provides a passenger ship passenger anti-seasickness seat to meet the needs. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a passenger ship seat that prevents seasickness, thereby solving the problems that existing means of preventing seasickness are limited, cannot keep passengers level when the ship is rocking or tilting, and cannot effectively prevent passengers from feeling uncomfortable when the ship is vibrating.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0006] A passenger ship seat designed to prevent seasickness includes a base, an inertial compensation structure on the top of the base, a seat body on the top of the inertial compensation structure, a lumbar restraint structure on the rear inner side of the seat body, and a leg restraint structure on the front inner side of the seat body.

[0010] The waist restraint structure also includes a second connecting post, a horizontal sleeve rod, a third connecting post, and a connecting sleeve block. The second connecting post is movably sleeved on one side of the connecting sleeve rod. A horizontal sleeve rod is fixedly installed on one side of the second connecting post. The third connecting post is fixedly sleeved on both sides of the horizontal sleeve rod. Connecting sleeve blocks are movably sleeved on both sides of the outer surface of the third connecting post.
[0011] The waist restraint structure also includes a connecting sleeve, a telescopic connecting rod, a limiting plate, and a wedge. The connecting sleeve is fixedly installed on one side of the connecting sleeve. The telescopic connecting rod is movably sleeved on both sides of the inner cavity of the connecting sleeve. The limiting plate is fixedly installed on one side of the third connecting column. A wedge is fixedly installed at one end of the telescopic connecting rod.
[0012] The waist restraint structure also includes an inclined plate, a limiting strip, a clamping rod, and a leather sleeve. The inclined plate is disposed on one side of the wedge block and is fixedly installed with the fixed shell. Limiting strips are fixedly installed on both sides of the inclined plate. A clamping rod is fixedly installed on one side of the wedge block, and a leather sleeve is fixedly sleeved on the outer surface of the clamping rod.
[0013] The leg restraint structure includes a connecting shaft, a leg rest, and a support rod. The connecting shaft is located inside the seat body, and the leg rest is fixedly sleeved on both sides of the outer surface of the connecting shaft. The support rod is fixedly installed on both sides of the leg rest.
[0014] The leg restraint structure also includes an air pump, an air inlet, and an air outlet. The leg plate is fixedly installed on one side of the air pump, an air inlet is fixedly installed on one side of the air pump, and air outlets are connected to both sides of the air pump.
[0015] A load-bearing frame is fixedly installed on the top of the receiving plate. An aluminum buffer honeycomb plate is fixedly installed in the inner cavity of the load-bearing frame. A first receiving plate is fixedly installed on the top of the aluminum buffer honeycomb plate. A first buffer pressure rod is fixedly installed on the top of the first receiving plate. A small spring is fixedly connected to the top of the first receiving plate. A second receiving plate is fixedly installed on the top of the small spring. A seat plate is fixedly installed on the top of the second receiving plate. A first connecting post is fixedly sleeved on one side of the seat plate. The first connecting post and the fixed shell are movably sleeved.
[0016] A telescopic tube is fixedly installed on the top of the fixed shell, and a headrest is fixedly installed on the top of the telescopic tube.
[0017] Compared with the prior art, the present invention has at least the following beneficial effects:
[0018] In the above solution, the lumbar restraint structure activates the servo motor when the bump sensor detects seat bumps. The motor shaft then rotates the rotating disc, which in turn rotates the rotating column. This pulls on one end of the two rotating columns and the connecting sleeve rod. The wedge is limited by the limiting strip, causing the connecting sleeve rod to be pulled inward, which in turn moves the two horizontal sleeve rods and the connecting sleeve shell inward. This, in turn, moves the two wedges inward on the inclined plate surface. Simultaneously, the two clamping rods and the leather sleeve retract inward, causing the sides of the seat back to tighten inward to restrain the passenger's abdomen and stomach, thereby forcibly stabilizing the body posture and reducing internal organ displacement and muscle tension.
[0019] In the above solution, through the leg restraint structure and headrest, when the passenger sits on the top of the seat body with their legs placed on one side of the leg rest, the air pump automatically starts when the seat body tilts and shakes. The air pump delivers gas from the air inlet through the air outlet to the inside of one side of the seat body. At this time, the side of the seat body will bulge after being filled with gas, thus restricting the passenger's legs. The headrest is equipped with a non-Newtonian fluid (shear-thickening type). When an external force is applied slowly (the passenger's head leans against it gently), the fluid is soft like a liquid gel, providing comfortable support. When subjected to a rapid and violent impact (such as the violent shaking of a ship), the viscosity of the liquid increases sharply, hardening into a solid-like state, absorbing energy and fixing the head. After the impact, the liquid returns to a soft state and can be reused. At this time, not only are the passenger's legs and waist forcibly stabilized, but head shaking is also reduced, avoiding visual blurring and vestibular signal conflict.
[0020] In the above solution, through the inertia compensation structure, when the seat body tilts to the left, the counterweight ball inside the groove will impact to the right due to inertia. At this time, it will pull the soft spring and the second buffer pressure rod, thereby pulling the leftward tilting support plate and the seat body on top of it to make a counterforce compensation, thus counteracting the swaying of the boat, keeping the passenger's body close to horizontal, reducing the acceleration stimulation to the vestibular system, and through the small spring, the first buffer pressure rod and the aluminum buffer honeycomb plate, high-frequency vibration filtering is performed to avoid continuous micro-vibrations. Thus, the tilt of the seat body can be corrected while avoiding seasickness caused by micro-vibrations. Attached Figure Description

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the lumbar restraint structure 4 includes a fixed shell 41, a limiting groove 42, a servo motor 43, a bump sensor 44, and a connecting rod 421. The fixed shell 41 is located inside the seat body 3. Limiting grooves 42 are formed on both sides of the surface of the fixed shell 41. The connecting rod 421 is fixedly installed on the inner side of the fixed shell 41. The servo motor 43 is fixedly sleeved in the inner cavity of the connecting rod 421. The bump sensor 44 is fixedly installed on one side of the servo motor 43. The lumbar restraint structure 4 also includes a motor shaft 45 and a rotating disc. 46. A rotating column 47 and a connecting sleeve rod 48 are included. A motor shaft 45 is fixedly installed at one end of the output shaft of a servo motor 43. A rotating disk 46 is fixedly installed at one end of the motor shaft 45. Rotating columns 47 are fixedly installed on both sides of the outer surface of the rotating disk 46.

The waist restraint structure 4 also includes a connecting sleeve shell 413, a telescopic connecting rod 414, a limiting plate 415, and a wedge block 416.

A limit plate 415 is fixedly installed on one side of the 1. A wedge block 416 is fixedly installed on one end of the telescopic connecting rod 414. The waist restraint structure 4 also includes an inclined plate 417, a limit strip 418, a clamping rod 419, and a leather sleeve 420. The inclined plate 417 is located on one side of the wedge block 416 and is fixedly installed to the fixed shell 41. Limit strips 418 are fixedly installed on both sides of the inclined plate 417. A clamping rod 419 is fixedly installed on one side of the wedge block 416, and a leather sleeve 420 is fixedly sleeved on the outer surface of the clamping rod 419.
[0043] The servo motor 43 is activated by the lumbar restraint structure 4, which then causes the motor shaft 45 to rotate the rotating disk 46 and thus the rotating column 47. At this time, the two rotating columns 47 and one end of the connecting sleeve rod 48 are pulled. The wedge block 416 is limited by the limit bar 418, so that when the connecting sleeve rod 48 is pulled, the two horizontal sleeve rods 410 and the connecting sleeve 413 will be moved inward, thereby moving the two wedge blocks 416 inward on the surface of the inclined plate 417. At the same time as the movement, the two clamping rods 419 and the leather sleeve 420 retract inward, thereby tightening the two sides of the backrest of the seat body 3 inward to restrain the passenger's abdomen and stomach, thereby reducing seasickness. Example
[0044] like Figure 2 , Figure 6 and Figure 7As shown, the leg restraint structure 5 includes a connecting shaft 51, a leg rest 52, and a support rod 53. The connecting shaft 51 is located inside the seat body 3. The leg rest 52 is fixedly sleeved on both sides of the outer surface of the connecting shaft 51. The support rod 53 is fixedly installed on both sides of the leg rest 52. The leg restraint structure 5 also includes an air pump 54, an air inlet 55, and an air outlet 56. The leg rest 52 is fixedly installed on one side of the air pump 54. The air inlet 55 is fixedly installed on one side of the air pump 54. The air outlet 56 is connected to both sides of the air pump 54. A load-bearing frame 9 is fixedly installed on the top of the support plate 213. The inner cavity of the load-bearing frame 9 is fixed. An aluminum buffer honeycomb panel 8 is installed. A first support plate 14 is fixedly installed on the top of the aluminum buffer honeycomb panel 8. A first buffer pressure rod 7 is fixedly installed on the top of the first support plate 14. A small spring 6 is fixedly connected to the top of the first support plate 14. A second support plate 15 is fixedly installed on the top of the small spring 6. A seat plate 11 is fixedly installed on the top of the second support plate 15. A first connecting post 10 is fixedly sleeved on one side of the seat plate 11. The first connecting post 10 and the fixed shell 41 are movably sleeved. A telescopic tube 12 is fixedly installed on the top of the fixed shell 41. A headrest 13 is fixedly installed on the top of the telescopic tube 12.
[0045] With the leg restraint structure 5 in place, when the passenger sits on top of the seat body 3 and places their legs on one side of the leg rest 52, the air pump 54 automatically starts when the seat body 3 tilts and shakes. The air pump 54 delivers air from the air inlet 55 through the air outlet 56 to the inside of one side of the seat body 3. When the air is filled, one side of the seat body 3 will bulge out, thus restricting the passenger's legs.
[0046] The technical solution provided by this invention first activates the servo motor 43 when the bump sensor 44 senses seat bumps. Then, the motor shaft 45 rotates the rotating disk 46, which in turn rotates the rotating column 47. This pulls on one end of the two rotating columns 47 and the connecting sleeve rod 48. The limiting strip 418 limits the wedge block 416, causing the connecting sleeve rod 48 to be pulled inwards, along with the two horizontal sleeve rods 410 and the connecting sleeve shell 413. This, in turn, causes the two wedge blocks 416 to move inwards on the surface of the inclined plate 417. Simultaneously, the two clamping rods 419... The leather cover 420 retracts inward, causing the sides of the seat body 3 backrest to tighten inward, thus restraining the passenger's abdomen and stomach, thereby forcibly stabilizing the body posture and reducing internal organ displacement and muscle tension. Then, when the passenger sits on the top of the seat body 3 and places their legs on one side of the leg rest 52, the air pump 54 automatically starts during tilting and shaking, sending air from the air inlet 55 through the air outlet 56 to the inside of one side of the seat body 3. At this time, after the air is filled, one side of the seat body 3 will bulge, restricting the passenger's legs. The headrest 13 is also equipped with a non-Newtonian fluid (shear fluid) inside. (Thickening type) When external force is applied slowly (passenger's head gently leans against it), the fluid is soft like a liquid gel, providing comfortable support. When subjected to rapid and violent impact (such as violent turbulence of a ship), the fluid viscosity increases sharply, hardening into a solid-like state, absorbing energy and fixing the head. After the impact, the fluid returns to a soft state and can be reused. At this time, not only are the passenger's legs and waist forcibly stabilized, but head sway is also reduced, avoiding visual blurring and vestibular signal conflict. Finally, when the seat body 3 tilts to the left, the counterweight ball 24 inside the groove 23 will due to inertia The movement of the seat causes it to sway to the right, which pulls the soft spring 27 and the second buffer pressure bar 28, thereby pulling the leftward tilting support plate 213 and the seat body 3 on top of it to make a counterforce compensation, thus counteracting the swaying of the boat and keeping the passenger's body close to horizontal. The acceleration stimulation of the vestibular system is reduced, and high-frequency vibration filtering is performed through the small spring 6, the first buffer pressure bar 7 and the aluminum buffer honeycomb plate 8 to avoid continuous small vibrations. In this way, the tilt of the seat body 3 can be corrected while avoiding seasickness caused by its small vibrations.
[0047] Finally, through the movement of the aforementioned device, the passenger's abdomen, stomach, and legs can be restrained to prevent seasickness. Furthermore, the counterforce applied to the seat body by the counterweight compensates for the reduced tilt, thereby maximizing the anti-seasickness effect.
