[0023] An embodiment of the present invention provides a safety seat for use in high-speed trains. The specific structure and function of the safety seat provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0024] Reference Figures 1 to 4 According to the first aspect of the present invention, the safety seat provided by the embodiment comprises: a base 100, a seating component 200 and a limiting component 300. The upper side of the base 100 is provided with a connecting rod 110 arranged in a horizontal direction, which serves as a connection and sliding guide structure between the seating component 200 and the base 100. The seating component 200 comprises a connecting frame 210, a seat cushion 220, a safety belt 230 and a limiting rod 240. Two arc-shaped slide grooves 211 are arranged at intervals on the rear side of the connecting frame 210, and the left and right ends of the connecting rod 110 are respectively inserted into the two arc-shaped slide grooves 211, so that the connecting frame 210 can slide relative to the connecting rod 110 along the arc-shaped slide grooves 211. The seat cushion 220 is arranged on the upper side of the connecting frame 210 to provide a sitting and lying space for the passenger. The safety belt 230 is arranged on the seat cushion 220 to fix the passenger and prevent him from flying out due to inertia. The limiting rod 240 is disposed on one side of the connecting frame 210, and cooperates with the limiting member 310 of the limiting assembly 300 to achieve the fixing and unlocking of the riding assembly 200. The seat cushion 220 is provided with a plurality of cavities 221, and the cavities 221 are filled with air and buffer, such as airbags and buffer gel, to provide additional buffering effect during emergency braking.

[0025] The limiting assembly 300 is arranged on the base 100 and is located 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 achieve the function of clamping or unlocking the limiting rod 240. When the high-speed train is running normally, the limiting member 310 is clamped on the limiting rod 240, so that the connecting frame 210 and the seat cushion 220 remain in an upright state, ensuring the riding comfort of the passengers. When the high-speed train brakes urgently, the limiting member 310 is separated 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 the action of 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 center of gravity of the passengers and reduce the impact force in the process of changing from an upright state to a lying state. Subsequently, the connecting frame 210 and the seat cushion 220 continue to slide to a dumped state, at which time the buffer in the seat cushion 220 plays a major buffering role, absorbing and dispersing the remaining impact force, thereby protecting the safety of the passengers to the greatest extent.

[0026] According to the safety seat provided by the embodiment of the first aspect of the present invention, when the high-speed train is in emergency braking, the safety belt 230 restrains the passenger on the seat cushion 220, the limiter 310 is separated from the limiter rod 240, and the limiter assembly 300 cooperates with the connecting rod 110 and the arc-shaped slide groove 211 to achieve a smooth transition of the riding assembly 200 from an upright state to a lying state and then to a dumped state in an emergency, effectively dispersing the impact force on the passenger. The cavity 221 filled with air and a buffer provided in the seat cushion 220 further enhances the buffering effect and reduces the possible damage to the passenger during emergency braking. In addition, the safety seat can maintain an upright state during normal driving, ensuring the comfort of the passengers and meeting the requirements of high-speed trains for safety seats.

[0027] Reference Figure 1 , Figure 3 as well as Figure 4According to the safety seat provided by the embodiment of the first aspect of the present invention, the limit assembly 300 includes a speed sensor 320 and an electromagnetic controller 330, both of which are arranged on the base 100, and the speed sensor 320 is used to monitor the running speed change of the train in real time. When the train is running at a normal speed, the signal output by the speed sensor 320 remains within a stable range; once the train is in emergency braking, the speed sensor 320 will immediately capture the sharp change in speed and output a corresponding emergency signal. The electromagnetic controller 330 is electrically connected to the speed sensor 320 and receives the signal from the speed sensor 320. The electromagnetic controller 330 is provided with a logic control circuit inside, which can judge the running state of the train according to the received signal. When receiving a signal of normal running, the electromagnetic controller 330 controls the limit member 310 to maintain a clamped state, firmly fixes the limit rod 240 at a predetermined position, ensures that the riding assembly 200 remains in an upright state, and provides a stable riding environment for passengers. However, in the case of emergency braking, the emergency signal output by the speed sensor 320 will trigger the emergency response mechanism in the electromagnetic controller 330. The electromagnetic controller 330 quickly adjusts the electromagnetic force it outputs, so that the limiter 310 changes from the clamping state to the unlocking state, that is, the limiter 310 can move away from the limiter rod 240. This change enables the connecting frame 210 and the seat cushion 220 to slide smoothly along the arc-shaped slide groove 211 under the action of inertia, and successively change to the lying state and the dumping state, thereby achieving effective impact buffering.

[0028] Reference Figure 3 and Figure 4 According to the safety seat provided by the embodiment of the first aspect of the present invention, the width of the arcuate 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 arcuate groove 211. In the early stage of emergency braking, when the connecting frame 210 and the seat cushion 220 just start to slide along the arcuate groove 211, the wider arcuate groove 211 portion can provide enough space for the connecting rod 110 to ensure smooth sliding and avoid poor sliding caused by friction or jamming. As the sliding process proceeds, the width of the arcuate groove 211 gradually decreases. This change produces a gradually increasing lateral restraining force on the connecting frame 210 and the seat cushion 220. This restraining force forms a certain angle with the sliding direction, which helps to 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 enables the connecting frame 210 and the seat cushion 220 to more smoothly disperse the impact force on the passenger during the process of changing from an upright state to a lying state and then to a tilted state.

[0029] In addition, since the width of the arc-shaped groove 211 gradually decreases, during the sliding process, as the width of the arc-shaped groove 211 decreases, the friction resistance between the connecting rod 110 and the inner wall of the arc-shaped groove 211 gradually increases, which further slows down the sliding speed of the connecting frame 210 and the seat cushion 220, prolongs the buffering time, and thus improves the overall buffering performance of the safety seat.

[0030] Reference Figures 1 to 4 According to the safety seat provided by the embodiment of the first aspect of the present invention, a thrust rubber gasket 120 is provided on the rear side of the base 100. The thrust rubber gasket 120 is made of high-quality rubber material with high elasticity and high wear resistance, which can ensure good buffering effect when impacted and maintain long-term stability and durability. The thrust rubber gasket 120 is set in front and behind the base 100, corresponding to the sliding direction of the connecting frame 210, so as to thrust the thrust plate 212. A thrust plate 212 is provided on the upper part of the connecting frame 210. The thrust plate 212 is integrally formed with the connecting frame 210 or firmly connected to ensure 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 rubber gasket 120 on the front side of the base 100.

[0031] When the high-speed train is braked urgently, the connecting frame 210 and the seat cushion 220 slide along the arc-shaped slide groove 211 and gradually fall down, and the thrust plate 212 gradually approaches the thrust rubber pad 120 as the connecting frame 210 tilts. Finally, when the tipping state reaches the limit, the thrust plate 212 firmly abuts against the thrust rubber pad 120. This not only effectively prevents the connecting frame 210 and the seat cushion 220 from further falling down, but also absorbs the remaining impact force through the buffering effect of the thrust rubber pad 120, thereby reducing the impact on passengers and the train structure.

[0032] Reference Figure 1 , Figure 3 as well as Figure 4According to the safety seat provided by the embodiment of the first aspect of the present invention, a connection seat 213 is provided on one side of the connection frame 210. The connection seat 213 can be a part integrally formed with the connection frame 210, or can be an independent component firmly fixed to the connection frame 210 by welding, bolt connection, etc. The design of the connection seat 213 takes into account the shape, size and required fixing strength of the limit rod 240 to ensure that a stable and reliable support platform can be provided. The limit rod 240 is fixed to this connection seat 213. The fixing method can be selected according to actual needs. For example, the limit rod 240 can be connected to the connection seat 213 by welding, or the limit rod 240 can be detachably fixed to the connection seat 213 by fasteners such as bolts and nuts. By fixing the limit rod 240 to the connection seat 213, the structure of the entire safety seat is made more compact and reasonable. During emergency braking, the limit rod 240 can accurately cooperate with the limit assembly 300 to realize the limit and unlocking functions of the connection frame 210 and the seat cushion 220, thereby ensuring the safety of the passengers.

[0033] Reference Figures 1 to 4 According to the safety seat provided by the embodiment of the first aspect of the present invention, the connecting frame 210 is provided with two armrests 214, and the armrests 214 are installed on the left and right sides of the connecting frame 210, forming a whole with the connecting frame 210, thereby ensuring the stability and durability of the armrests 214. The material of the armrests 214 can be selected from materials with good touch and anti-slip properties, such as high-quality plastics, rubber or soft metal coatings, to provide passengers with a more comfortable grip experience. Along the front and back directions, the upper end surface of the armrest 214 is arc-shaped. This arc-shaped design not only conforms to the principles of ergonomics, can fit the natural arm posture of passengers during riding, reduce fatigue during long-term riding, but also can provide passengers with additional support and protection in emergency situations such as emergency braking. When the train brakes in an emergency, passengers can instinctively grab the armrests 214 to stabilize their bodies and avoid injuries due to inertial impact.

[0034] Reference Figure 1 According to the safety seat provided by the embodiment of the first aspect of the present invention, the left and right sides of the connecting frame 210 are connected with support plates 215, and the support plates 215 perfectly match the contours of the connecting frame 210 and the armrest 214, forming an overall structure that is both beautiful and practical. The support plate 215 is installed below the armrest 214, so that the support plate 215 can disperse the passenger weight and impact force borne by the armrest 214, reducing the risk of damage to the armrest 214 due to long-term force; in addition, the support plate 215 can also provide passengers with a more spacious riding space, avoiding riding discomfort caused by the armrest 214 being too high.

[0035] It is understandable that the presence of the support plate 215 also makes the overall structure of the safety seat more stable. In extreme situations such as emergency braking, the support plate 215 can form a stable support system together with the connecting frame 210 and the armrest 214 to effectively protect the passenger from injury. At the same time, the design of the support plate 215 also takes into account young passengers, so that young passengers can lean on it.

[0036] Reference Figure 3 and Figure 4 According to the safety seat provided by the embodiment of the first aspect of the present invention, a first installation cavity is provided on the upper part of the seat cushion 220, and a head airbag 250 is installed in the first installation cavity. The design of the first installation cavity takes into account the deployment space and installation convenience of the airbag. The first installation cavity has sufficient depth and width to accommodate the airbag when it is not inflated, and allows it to be freely deployed when necessary. At the same time, the opening position of the installation cavity can be set according to actual needs to ensure that the airbag will not be hindered when deployed and can be quickly and smoothly expanded to a predetermined position. The safety seat of this embodiment not only provides passengers with basic riding functions, but also provides additional safety protection for the passengers' heads in emergency situations. The rapid deployment of the head airbag 250 can effectively reduce the impact on the head of the passenger during emergency braking, reduce the risk of injury, and further improve the safety performance of the safety seat.

[0037] Reference Figure 3 and Figure 4 According to the safety seat provided by the embodiment of the first aspect of the present invention, a second installation cavity is provided at the lower part of the seat cushion 220, and a foot airbag 260 is installed in the second installation cavity. The design concept of the foot airbag 260 is similar to that of the head airbag 250, both of which are to be able to be quickly inflated and deployed in the event of an emergency on a high-speed train, to provide an additional cushioning layer for the passenger's feet, thereby minimizing injuries. In this embodiment, the second installation cavity is arranged at the lower part of the seat cushion 220, which closely corresponds to the position of the passenger's feet. In this way, in an emergency, the foot airbag 260 can be quickly deployed and cover the passenger's feet, effectively preventing foot injuries caused by inertial impact.

[0038] The structural design of the second installation cavity fully considers the storage and deployment requirements of the airbag. The second installation cavity must not only be able to accommodate the airbag when it is not inflated, but also ensure that the airbag can be deployed quickly and without obstacles in an emergency. Therefore, the size, shape and opening direction of the installation cavity have been carefully calculated and designed to ensure that the airbag can be deployed quickly and accurately.

[0039] According to the high-speed train provided by the embodiment of the second aspect of the present invention, the high-speed train has all the beneficial effects of the embodiment of the first aspect of the present invention.

[0040] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
