Description

Technical Field

[0001] This invention relates to the field of safety seat technology, and in particular to a safety seat and a high-speed train. Background Technology

[0002] Currently, my country's high-speed maglev trains lead the high-speed rail industry with a designed operating speed of 600 km / h, providing the public with a faster mode of travel. However, increased speed also brings challenges: passengers may experience significant inertial impact during emergency braking, and ultra-high speeds increase the risk of train rollover and derailment. Given the spacious seating area and large window area of ​​high-speed trains, it is difficult to accommodate traditional safety devices such as seat belts and airbags found in cars, making passenger protection in emergency situations a key concern. Therefore, developing an independent safety seat that ensures both passenger comfort and effective safety protection is particularly important. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a safety seat that effectively solves the problem of large inertial impact that passengers may suffer during emergency braking of high-speed trains, significantly improving passenger safety.

The cavity filled with air and buffer solution within the seat cushion further enhances the cushioning effect, reducing the potential injury to the passenger during emergency braking. Furthermore, this safety seat can maintain an upright position during normal travel, ensuring passenger comfort and meeting the requirements for safety seats on high-speed trains.

[0011] According to a first aspect of the present invention, the safety seat provided includes a limiting component comprising a speed sensor and an electromagnetic controller, both of which are disposed on the base, and a limiting member disposed on the electromagnetic controller.

[0034] The present invention provides a safety seat for use on high-speed trains. The specific structure and function of the safety seat provided by the present invention will be further described below with reference to the text and accompanying drawings.

[0035] Reference Figures 1 to 4 According to a first aspect embodiment of the present invention, a safety seat includes: a base 100, a seating component 200, and a limiting component 300. A horizontally arranged connecting rod 110 is provided on the upper side of the base 100, serving as a connection and sliding guide structure between the seating component 200 and the base 100. The seating component 200 includes a connecting frame 210, a seat cushion 220, a seat belt 230, and a limiting rod 240. Two arc-shaped grooves 211 are spaced apart on the rear side of the connecting frame 210. The left and right ends of the connecting rod 110 are respectively engaged in these two arc-shaped grooves 211, allowing the connecting frame 210 to slide relative to the connecting rod 110 along the arc-shaped grooves 211. The seat cushion 220 is located on the upper side of the connecting frame 210, providing a sitting / lying space for the passenger. The seat belt 230 is located on the seat cushion 220 to secure the passenger and prevent them from being thrown out due to inertia. The limiting rod 240 is located on one side of the connecting frame 210 and cooperates with the limiting member 310 of the limiting assembly 300 to fix and unlock the seating assembly 200. The seat cushion 220 has multiple cavities 221, which are filled with air and buffer solutions, such as airbags and cushioning gel, to provide additional cushioning during emergency braking.

[0036] The limiting assembly 300 is located on the base 100 and on one side of the limiting rod 240, and mainly includes a limiting member 310. The limiting member 310 can move toward or away from the limiting rod 240 to lock or unlock the limiting rod 240. When the high-speed train is running normally, the limiting member 310 is engaged with the limiting rod 240, keeping the connecting frame 210 and the seat cushion 220 upright, ensuring passenger comfort. When the high-speed train brakes suddenly, the limiting member 310 separates from the limiting rod 240, and the connecting frame 210 and the seat cushion 220 slide forward relative to the connecting rod 110 along the arc-shaped slide groove 211 under inertia. Due to the design of the arc-shaped slide groove 211, the connecting frame 210 and the seat cushion 220 can gradually lower the passenger's center of gravity and reduce impact force during the transition from an upright to a reclining state. Subsequently, the connecting frame 210 and the seat cushion 220 continue to slide to the tilted state. At this time, the buffer solution in the seat cushion 220 plays the main role in cushioning, absorbing and dispersing the remaining impact force, thereby protecting the safety of passengers to the greatest extent.

[0037] According to the first aspect of the present invention, in the case of a safety seat provided by a high-speed train during emergency braking, the seat belt 230 restrains the passenger to the seat cushion 220, the limiting member 310 separates from the limiting rod 240, and the cooperation of the limiting component 300 with the connecting rod 110 and the arc-shaped slide groove 211 enables a smooth transition of the seating component 200 from an upright state to a reclining state and then to a tilted state in an emergency, effectively dispersing the impact force on the passenger. The cavity 221 filled with air and buffer solution provided inside the seat cushion 220 further enhances the cushioning effect and reduces the potential injury to the passenger during emergency braking. Furthermore, this safety seat can maintain an upright position during normal operation, ensuring passenger comfort and meeting the requirements of high-speed trains for safety seats.

[0038] Reference Figure 1 , Figure 3 as well as Figure 4According to a first aspect embodiment of the present invention, the limiting component 300 of the safety seat includes a speed sensor 320 and an electromagnetic controller 330, both of which are disposed on the base 100. The speed sensor 320 is used to monitor changes in the train's operating speed in real time. When the train is traveling at a normal speed, the signal output by the speed sensor 320 remains within a stable range; however, once the train undergoes emergency braking, the speed sensor 320 immediately detects the rapid change in speed and outputs a corresponding emergency signal. The electromagnetic controller 330 is electrically connected to the speed sensor 320 and receives signals from the speed sensor 320. The electromagnetic controller 330 has an internal logic control circuit that can determine the train's operating status based on the received signals. When a signal indicating normal operation is received, the electromagnetic controller 330 controls the limiting component 310 to remain in a locked state, firmly fixing the limiting rod 240 in a predetermined position, ensuring that the seating component 200 remains upright and providing a stable seating environment for passengers. However, in the event of emergency braking, the emergency signal output by the speed sensor 320 will trigger the emergency response mechanism within the electromagnetic controller 330. The electromagnetic controller 330 quickly adjusts its output electromagnetic force, causing the limiting member 310 to change from a locked state to an unlocked state, meaning the limiting member 310 can move away from the limiting rod 240. This change allows the connecting frame 210 and the seat cushion 220 to slide smoothly along the arc-shaped slide groove 211 under inertia, and sequentially change to a reclining state and a tilting state, thereby achieving effective impact cushioning.

[0039] Reference Figure 3 and Figure 4 According to the first aspect of the present invention, in the safety seat provided, the width of the arc-shaped groove 211 gradually decreases along the direction in which the connecting frame 210 and the seat cushion 220 can slide forward relative to the connecting rod 110 along the arc-shaped groove 211. In the initial stage of emergency braking, when the connecting frame 210 and the seat cushion 220 just begin to slide along the arc-shaped groove 211, the wider portion of the arc-shaped groove 211 provides sufficient space for the connecting rod 110, ensuring smooth and unobstructed sliding and avoiding sliding difficulties caused by friction or jamming. As the sliding process progresses, the width of the arc-shaped groove 211 gradually decreases, and this change generates a gradually increasing lateral constraint force on the connecting frame 210 and the seat cushion 220. This constraint force forms a certain angle with the sliding direction, which helps guide the connecting frame 210 and the seat cushion 220 to slide smoothly along a predetermined trajectory and gradually reduce their sliding speed. This not only improves the stability of the sliding process, but also allows the connecting frame 210 and seat cushion 220 to more smoothly distribute the impact force on the passenger during the process of changing from an upright state to a reclining state and then to a tilting state.

[0040] In addition, as the width of the arc-shaped groove 211 gradually decreases, the frictional resistance between the connecting rod 110 and the inner wall of the arc-shaped groove 211 gradually increases during the sliding process. This further slows down the sliding speed between the connecting frame 210 and the seat cushion 220, prolongs the buffer time, and thus improves the overall buffering performance of the safety seat.

[0041] Reference Figures 1 to 4 According to the first aspect of the present invention, a thrust-resistant rubber pad 120 is provided on the rear side of the base 100. The thrust-resistant rubber pad 120 is made of high-quality rubber material with high elasticity and high wear resistance, which can ensure good cushioning effect when subjected to impact, and maintain long-term stability and durability. The thrust-resistant rubber pad 120 is set at the front and rear of the base 100, corresponding to the sliding direction of the connecting frame 210, so as to resist the thrust of the thrust plate 212. The thrust plate 212 is provided on the upper part of the connecting frame 210. The thrust plate 212 is integrally formed or firmly connected to the connecting frame 210, ensuring its structural strength and stability. When the connecting frame 210 and the seat cushion 220 are tilted, the thrust plate 212 can accurately abut against the thrust-resistant rubber pad 120 on the front side of the base 100.

[0042] When a high-speed train brakes suddenly, as the connecting frame 210 and seat cushion 220 slide along the arc-shaped groove 211 and gradually tilt, the thrust plate 212 gradually moves closer to the thrust rubber pad 120 as the connecting frame 210 tilts. Finally, when the tilting reaches its limit, the thrust plate 212 firmly abuts against the thrust rubber pad 120. This not only effectively prevents further tilting of the connecting frame 210 and seat cushion 220, but also absorbs the remaining impact force through the cushioning effect of the thrust rubber pad 120, reducing the impact on passengers and the train structure.

[0043] Reference Figure 1 , Figure 3 as well as Figure 4According to the first aspect of the present invention, a safety seat has a connecting seat 213 on one side of the connecting frame 210. The connecting seat 213 can be integrally formed with the connecting frame 210, or it can be an independent component firmly fixed to the connecting frame 210 by welding, bolting, or other means. The design of the connecting seat 213 takes into account the shape, size, and required fixing strength of the limiting rod 240, ensuring that a stable and reliable support platform can be provided. The limiting rod 240 is fixed to this connecting seat 213. The fixing method can be selected according to actual needs. For example, the limiting rod 240 can be connected to the connecting seat 213 by welding, or the limiting rod 240 can be detachably fixed to the connecting seat 213 by bolts, nuts, or other fasteners. By fixing the limiting rod 240 to the connecting seat 213, the structure of the entire safety seat becomes more compact and reasonable. During emergency braking, the limiting rod 240 can accurately cooperate with the limiting component 300 to realize the limiting and unlocking functions of the connecting frame 210 and the seat cushion 220, thereby ensuring the safety of the passenger.

[0044] Reference Figures 1 to 4 According to the first aspect of the present invention, the safety seat provided has a connecting frame 210 with two armrests 214. The armrests 214 are installed on the left and right sides of the connecting frame 210, forming an integral whole with the connecting frame 210, ensuring the stability and durability of the armrests 214. The material of the armrests 214 can be selected from materials with good tactile feel and anti-slip properties, such as high-quality plastic, rubber, or soft metal covering, to provide passengers with a more comfortable gripping experience. The upper surface of the armrests 214 is arc-shaped along the front-to-back direction. This arc design not only conforms to ergonomic principles, conforming to the natural arm posture of passengers during riding and reducing fatigue during long journeys, but also provides additional support and protection for passengers in emergency situations such as emergency braking. When the train brakes suddenly, passengers can instinctively grab the armrests 214 to stabilize their bodies and avoid injury due to inertial impact.

[0045] Reference Figure 1 According to the first aspect of the present invention, the safety seat has support plates 215 connected to the left and right sides of the connecting frame 210. The support plates 215 perfectly fit the contours of the connecting frame 210 and the armrest 214, forming an aesthetically pleasing and practical overall structure. Installing the support plates 215 below the armrest 214 allows the support plates 215 to distribute the passenger weight and impact force borne by the armrest 214, reducing the risk of damage to the armrest 214 due to long-term stress. Furthermore, the support plates 215 also provide passengers with more spacious seating space, avoiding discomfort caused by the armrest 214 being too high.

[0046] Understandably, the presence of the support plate 215 also makes the overall structure of the child safety seat more stable. In extreme situations such as emergency braking, the support plate 215, together with the connecting frame 210 and the armrest 214, can form a stable support system, effectively protecting passengers from injury. At the same time, the design of the support plate 215 also takes into account younger passengers, allowing them to hold on.

[0047] Reference Figure 3 and Figure 4 According to a first aspect embodiment of the present invention, a safety seat has a first mounting cavity on the upper part of the seat cushion 220, within which a head airbag 250 is installed. The design of the first mounting cavity takes into account the deployment space and ease of installation of the airbag. The first mounting cavity has sufficient depth and width to accommodate the deflated airbag and allow it to deploy freely when needed. Simultaneously, the opening position of the mounting cavity can be set according to actual needs to ensure that the airbag is not obstructed during deployment and can quickly and smoothly inflate to the predetermined position. The safety seat of this embodiment not only provides passengers with basic seating functions but also provides additional head protection for passengers in emergency situations. The rapid deployment of the head airbag 250 effectively reduces the head impact suffered by passengers during emergency braking, lowers the risk of injury, and further enhances the safety performance of the safety seat.

[0048] Reference Figure 3 and Figure 4 According to a first aspect embodiment of the safety seat provided by the present invention, a second mounting cavity is provided at the lower part of the seat cushion 220, and a foot airbag 260 is installed in the second mounting cavity. The design concept of the foot airbag 260 is similar to that of the head airbag 250, both being designed to inflate and deploy rapidly in the event of a sudden incident on a high-speed train, providing an additional cushioning layer for the passenger's feet, thereby minimizing injury. In this embodiment, the second mounting cavity is located at the lower part of the seat cushion 220, closely corresponding to the position of the passenger's feet. Thus, in an emergency, the foot airbag 260 can quickly deploy and cover the passenger's feet, effectively preventing foot injuries caused by inertial impact.

[0049] The structural design of the second mounting cavity fully considers the storage and deployment requirements of the airbag. The second mounting cavity must not only be able to accommodate the deflated airbag, but also ensure that the airbag can deploy quickly and without obstruction in an emergency. Therefore, the size, shape, and opening direction of the mounting cavity have been carefully calculated and designed to ensure that the airbag deployment is both rapid and accurate.

[0050] The high-speed train provided according to the second aspect of the present invention has all the beneficial effects of the first aspect of the present invention.

[0051] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
