Description

Technical Field

[0001] This utility model belongs to the field of seating technology, and in particular relates to a rotatable rail vehicle seat. Background Technology

[0002] Rail vehicle seats refer to passenger seats installed in rail transit vehicles such as high-speed rail, subway, and train. Their core function is to provide passengers with a safe and comfortable riding experience. At the same time, they need to adapt to the special needs of high-speed operation, frequent rerouting, and high-density passenger flow. Traditional rail vehicle seats usually adopt manual or automatic rotating design, mainly focusing on optimizing basic performance such as backrest angle and seat cushion hardness around ergonomics. However, they have obvious shortcomings in air quality management and comprehensive space utilization.

[0003] Existing rail vehicle seats primarily focus on passenger comfort, lacking integrated design for managing the carriage environment. The internal space of the seat base is often occupied by mechanical structures (such as rotating shafts and locking devices), failing to fully utilize its potential for functional expansion. This results in the seat functioning merely as a "static seating unit," unable to participate in carriage air circulation or odor control. In high-density passenger scenarios, especially during summer or long-distance travel, poor ventilation in the passenger's foot area easily leads to the accumulation of sweat, shoe and sock odors, and volatile gases from food residue (such as ammonia and hydrogen sulfide). Current odor control relies on a centralized air conditioning filtration system at the top of the carriage. However, centralized ventilation is insufficient to effectively cover localized dead zones such as the seat bottom, preventing timely elimination of foot odors. Furthermore, traditional seat bases lack integrated directional airflow channels, resulting in the inability to locally purify foot odors.

[0004] To address these issues, we provide a rotatable rail vehicle seat. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable rail vehicle seat. Through the cooperation of circulation and purification components, it solves the problem in the prior art that odor control relies on a centralized air conditioning filtration system on the top of the carriage, and that centralized ventilation is difficult to effectively cover local dead corners such as the bottom of the seat, and that foot odor cannot be eliminated in time.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a rotatable rail vehicle seat, comprising a base, a rotating mechanism inside the base, locking plates fixedly connected to both sides of the base, a seat fixedly connected to the top of the rotating mechanism, a circulation assembly inside the base, the circulation assembly comprising a main suction pipe fixedly connected inside the base, a suction pipe connected to one side of the main suction pipe, a suction nozzle connected to one side of the suction pipe, an air outlet pipe located at the bottom of the base, and an air outlet nozzle connected to the bottom of the air outlet pipe, and a purification assembly inside the base, the purification assembly comprising a purification box fixedly connected inside the base, an MOF filter located inside the purification box, and a fan fixedly connected inside the purification box.

[0008] The present invention is further configured such that the rotating mechanism includes a drive motor fixedly connected inside the base, a driving bevel gear fixedly connected to the output end of the drive motor, a driven bevel gear meshing on the surface of the driving bevel gear, and a rotating rod fixedly connected inside the driven bevel gear, the top of the rotating rod being fixedly connected to the bottom of the seat.

[0009] The present invention is further configured such that the number of main suction tubes is four, and two main suction tubes are arranged in a group, one above the other, inside the base on one side.

[0010] The present invention is further configured such that an air intake groove is provided on the side of the base near the suction nozzle, and a dustproof mesh is magnetically attached inside the air intake groove.

[0011] The present invention is further configured such that a connecting pipe is connected to one side of the main suction pipe, and the end of the connecting pipe away from the main suction pipe extends into the interior of the purification box, and the connecting pipe is located on the side of the MOF filter away from the fan.

[0012] The present invention is further configured such that the purification box is provided with a limiting groove adapted to the MOF filter, an ultraviolet lamp is fixedly connected inside the purification box, and a sound-absorbing plate is fixedly connected inside the purification box.

[0013] The present invention is further configured such that a partition is fixedly connected inside the purification box and between the fan and the MOFs filter, the air inlet of the fan extends to the side of the partition near the MOFs filter, the air outlet of the fan is connected to the air outlet pipe through a pipe, a protective box is fixedly connected to the bottom of the base, the air outlet pipe is fixedly connected inside the protective box, and an air outlet slot is provided at the bottom of the protective box.

[0014] The present invention has the following beneficial effects.

[0015] 1. This invention significantly improves odor purification efficiency through the synergistic effect of MOF (Metal-Oxide-Film) filters and ultraviolet lamps. The MOF filters, with their ultra-high specific surface area and customizable pore size, precisely adsorb small-molecule odor substances such as ammonia and hydrogen sulfide, with an adsorption capacity more than 10 times that of traditional activated carbon. The ultraviolet lamps periodically irradiate the filters, decomposing the adsorbed organic matter and restoring their adsorption capacity, extending the filter life to more than 5 years and significantly reducing replacement frequency. Simultaneously, the circulation component uses two sets of main suction pipes and nozzles to directionally collect odorous air from the foot area, which is then forcibly transported to the purification chamber by a fan, achieving highly efficient localized purification and avoiding the purification blind spots of traditional centralized air conditioning systems. This is particularly suitable for train environments with high passenger density.

[0016] 2. This utility model integrates the rotating mechanism and air circulation purification system within the seat base, making full use of the gaps in the mechanical structure to arrange the air ducts and achieve space reuse. When the seat rotates, the drive motor drives the rotating rod through a bevel gear set to adjust the seat orientation. At the same time, the circulation component automatically optimizes the priority of the air intake area to ensure that the purification efficiency is dynamically matched with the seat orientation. In addition, the magnetic dustproof net, limiting groove, and modular purification box design support quick assembly and disassembly. The sound-absorbing panel and protective box further reduce noise and equipment wear, balancing functionality and ease of maintenance, providing an innovative paradigm for the intelligent upgrading of rail vehicle seats.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A purification component is set inside the base 1, including a purification box 10 fixedly connected inside the base 1, and a MOF filter 11 located inside the purification box 10. The MOF filter 11 is a metal organic framework filter, which is a porous crystalline material formed by the self-assembly of metal ions / clusters and organic ligands through coordination bonds. Its unique structure gives the MOF filter 11 super adsorption capacity and selectivity, making it a cutting-edge technology for efficient odor elimination. The fan 12, which is fixedly connected inside the purification box 10, achieves odor adsorption, decomposition and long-term purification through the setting of purification components and efficient filtration and regeneration technology.

[0028] Example 2

[0029] Please see Figures 1-5Based on Embodiment 1, the rotating mechanism 2 includes a drive motor 201 fixedly connected inside the base 1, a driving bevel gear 202 fixedly connected to the output end of the drive motor 201, a driven bevel gear 203 meshing with the surface of the driving bevel gear 202, and a rotating rod 204 fixedly connected inside the driven bevel gear 203. The top of the rotating rod 204 is fixedly connected to the bottom of the seat 4. The rotating mechanism 2 is used to rotate and adjust the orientation of the seat 4 after the rail vehicle changes its direction of travel. There are four main suction tubes 5. Two main suction pipes 5 are arranged vertically on one side inside the base 1. These two sets of main suction pipes 5 are used to absorb odors from the front and back of the base 1. An air intake channel is provided on the side of the base 1 near the suction nozzle 7. A dust filter 13 is magnetically attached inside the air intake channel. The air intake channel and dust filter 13 allow airflow to be drawn into the suction nozzle 7, filtering the dust in the intake airflow. A connecting pipe 14 is connected to one side of each main suction pipe 5. The end of the connecting pipe 14 away from the main suction pipe 5 extends into the purification box 10. The connecting pipe 14 is located at MO. The MOF filter 11, located away from the fan 12, is connected to the main suction pipe 5 via a connecting pipe 14, which transports the air drawn in by the main suction pipe 5 to the purification chamber 10. The purification chamber 10 contains a limiting groove adapted to the MOF filter 11. An ultraviolet lamp and a sound-absorbing plate 15 are fixedly connected inside the purification chamber 10. The limiting groove helps to limit the position of the MOF filter 11 for easy replacement. The ultraviolet lamp periodically irradiates the MOF filter 11 to restore its adsorption capacity. The sound-absorbing panel 15 is used to reduce the noise of the fan 12. Inside the purification box 10, between the fan 12 and the MOF filter 11, a partition 16 is fixedly connected.

An air outlet slot is opened at the bottom of the protective box 17. The protective box 17 protects the air outlet pipe 8.

[0030] The working principle of this utility model is as follows: When it is necessary to rotate the seat 4 to adjust the orientation of the seat 4, the locking plate 3 is disengaged, the drive motor 201 drives the active bevel gear 202 to rotate, the active bevel gear 202 drives the driven bevel gear 203 to rotate, the driven bevel gear 203 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the seat 4 to rotate, thus adjusting the orientation of the seat 4. After the adjustment is completed, the locking plate 3 can be locked again.

[0031] During the operation of the rail vehicle, the fan 12 will be activated. The fan 12 will generate suction to draw the right side of the purification box 10 into negative pressure. At this time, the air near the base 1 will enter the suction pipe 6 and the main suction pipe 5 through the suction nozzle 7, and enter the purification box 10 through the connecting pipe 14 connected to the main suction pipe 5. The air will be purified by the MOF filter 11 in the purification box 10. The purified air will be delivered to the air outlet pipe 8 and blown downward through the air outlet 9 to purify the surrounding air and form an air circulation.
