[0004] The overall design of the existing handrail end structure has ventilation holes on the surface of the horizontal fixing rod and the ring for continuous air supply; the ventilation state and ventilation volume of the existing structure are difficult to control. When there are no passengers holding the handrail or when there are many passengers holding the handrail or when there is a lot of sweat on the palms of the passengers, it is difficult to perform adaptive control and adjustment. The overall ventilation consumption is high, and it is difficult to meet the ventilation and drying needs of different types of passengers for the palms. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] See attached Figure 1 -Attached Fig. 9A combined handrail in a rail transit carriage, comprising a ventilation duct 100 connected to a ventilation device, and a handrail device installed outside the ventilation duct 100, the handrail device surface is provided with ventilation holes, the handrail device comprises a first handrail assembly 200 with a first ventilation hole 414 on the surface, and a second handrail assembly 300 with a second ventilation hole 330 on the surface; the cross-sectional size of the first handrail assembly 200 is greater than the cross-sectional size of the second handrail assembly 300, and the second handrail assembly 300 partially extends into the first handrail assembly 200 and It can be rotated with it and can be set as a combination of multiple first handrail assemblies 200 and second handrail assemblies 300 to cover the surface of the ventilation duct 100. Rail transit passengers can hold the first handrail assembly 200 and the second handrail assembly 300 respectively to ensure stability during the operation of rail transit; at the same time, comfortable air can be blown out through the first ventilation holes 414 and the second ventilation holes 330 to dry the sweat on the palms of the passengers, dry the palms of the passengers, improve the passenger's holding experience, increase the holding friction, and ensure the stability of the passenger's holding.

[0034] Here, through the combined design of the first armrest assembly 200 and the second armrest assembly 300, the longer ventilation duct 100 can be divided into multiple parallel rotatable parts to meet the holding and ventilation needs of different passengers; at the same time, the first armrest assembly 200 can tightly install the second armrest assembly 300, ensuring the stability of the overall structure after installation and extending the service life of the overall equipment.

[0035] The ventilation equipment here is an air supply equipment, which can maintain the pressure inside the ventilation duct 100 greater than the pressure outside, allowing the gas to be discharged from the second ventilation hole 330 and the first ventilation hole 414, and blow air toward the palms of the passengers to dry the palms. At the same time, a heating wire can be built in to deliver warm dry gas to further increase the drying effect on the palms of the passengers.

[0036] Please refer to the attached Figure 4 A first ventilation opening 110 and a second ventilation opening 120 are provided on the side wall of the ventilation duct 100, a first control opening 221 communicating with the first ventilation hole 414 is provided on the inner wall of the first armrest assembly 200, and a second control opening 312 communicating with the second ventilation hole 330 is provided on the inner wall of the second armrest assembly 300; during the ventilation process, the first armrest assembly 200 is rotated to make the first ventilation opening 110 and the first control opening 221 relative to each other to realize the conduction of the first ventilation hole 414, and the second armrest assembly 300 is rotated to make the second ventilation opening 120 and the second control opening 312 relative to each other to realize the conduction of the second ventilation hole 330.

[0037] Through the above-mentioned structural design, passengers can adjust the rotation state of the first armrest assembly 200 and the second armrest assembly 300 according to their own needs to control the corresponding ventilation openings, control the openings to be relative or staggered, so as to control the ventilation state and the amount of ventilation, and realize adaptive adjustment. At this time, the first armrest assembly 200 and the second armrest assembly 300 can form a control valve state inside to realize targeted ventilation, thereby improving the targetedness and accuracy of ventilation and drying, and improving the ventilation effect of a single passenger, while being able to reduce the working power of the air supply equipment and reduce the overall energy consumption.

[0038] Please refer to the attached Figure 5 Specifically, the second armrest assembly 300 includes a first armrest sleeve 310 sleeved on the outside of the ventilation duct 100, and a ventilation interlayer 311 for connecting the second armrest assembly 300 and the second control opening 312 is opened inside the first armrest sleeve 310. The second control opening 312 is controlled to be opposite to the second ventilation opening 120 by rotating the first armrest sleeve 310. At this time, the gas in the ventilation duct 100 can pass through the second ventilation opening 120 and the second control opening 312 into the ventilation interlayer 311, and is blown out from the plurality of second ventilation holes 330 to achieve efficient ventilation; the setting position of the second ventilation holes 330 here can be adjusted according to the passenger's holding posture.

[0039] A first torsion elastic component is installed between the inner wall of the first armrest glove 310 and the outer wall of the ventilation duct 100. A gripping protrusion 320 is fixed on the surface of the first armrest glove 310 along the length direction. The gripping protrusion 320 can be provided to facilitate the passenger to grip the first armrest glove 310 while controlling the rotation of the first armrest glove 310, thereby increasing the gripping force arm and allowing the passenger's palm to be in an unfolded state, thereby ventilating and drying the palm. By providing the first torsion elastic component, when the passenger no longer grips the first armrest glove 310, the first armrest glove 310 can be automatically reset under the action of the first torsion elastic component, so that the second control opening 312 and the second ventilation opening 120 are in a staggered relatively closed state. At this time, the ventilation state on the surface of the second armrest component 300 is automatically closed, and the passenger does not need to manually adjust it. This improves the user experience and further reduces the overall loss.

[0040] A step surface 211 is provided on the side wall of the first armrest assembly 200 for installing the first armrest glove 310. Wind guide protrusions 313 are fixed at intervals on the end surfaces of both sides of the first armrest glove 310. By setting the step surface 211, both ends of the second armrest assembly 300 can partially extend into the step surface 211 to form a bent ventilation channel; at the same time, by setting the wind guide protrusion 313, the ventilation channel can be prevented from being in a completely closed state to ensure normal airflow; when the second armrest assembly 300 is in a reset state, the second control opening 312 and the second ventilation opening 120 are in a closed state. At this time, the gas is blown out from the inner wall of the first armrest glove 310 through the step surfaces 211 on both sides and is blown out in parallel from both sides, acting on the outer surface of the first armrest glove 310 to accelerate the drying of the surface of the first armrest glove 310 and provide a dry holding environment for the next passenger to hold; at the same time, the breeding of bacteria is avoided and the risk of virus transmission is reduced.

[0041] See attached drawings Figure 6 , Attachment Figure 7 Specifically, the first armrest assembly 200 includes a second armrest sleeve 210 sleeved on the outside of the ventilation duct 100. The second armrest sleeve 210 is rotatably connected to the ventilation duct 100 and is provided with a second torsion elastic assembly 230. The first ventilation opening 110 and the first control opening 221 are staggered by the second torsion elastic assembly 230. The first armrest assembly 200 can be in a normally closed state through the second torsion elastic assembly 230 to ensure that the gas circulation can be automatically closed when there is no passenger holding it, thereby reducing the loss of the ventilation equipment.

[0042] It should be noted here that the second torsion elastic component 230 and the first torsion elastic component here both include an inner retaining ring, an outer retaining ring and a torsion elastic member installed between the inner retaining ring and the outer retaining ring. A first strip-shaped positioning strip 231 is fixed to the inner wall of the inner retaining ring, and a continuous positioning groove 130 is opened on the side wall of the ventilation duct 100. During the installation process, the first positioning strip 231 on the surface of the inner retaining ring is aligned with the positioning groove 130 to complete the preliminary positioning of the first armrest component 200 and the second armrest component 300. The first armrest component 200 and the second armrest component 300 are slid to the predetermined positions corresponding to the first ventilation opening 110 and the second ventilation opening 120 to complete the installation of the overall structure.

[0043] The second arm glove 210 here can be designed as a double layer, and an inner ring 220 is detachably installed in the second arm glove 210, and the first control opening 221, the wind control baffle 222, the second torsion elastic component 230 and other structures are all installed in the inner ring 220. At the same time, a second positioning strip 223 is fixed on the outer side of the inner ring 220, and the second positioning strip 223 can be slidably inserted into the second arm glove 210 to complete the locking positioning, so as to ensure that the second arm glove 210 and the inner ring 220 rotate synchronously; through the above-mentioned structural design, the inner ring 220 can be processed separately, which reduces the difficulty of the overall processing and the manufacturing cost. At the same time, the inner ring 220 can be adaptively replaced to meet the adaptive installation of ventilation ducts 100 of different sizes.

[0044] In order to further meet the passengers' gripping needs, a handle 400 is fixed to the side wall of the second handrail glove box 210, and the handle 400 includes a handle ring 410. The handle ring 410 is a ring with a handrail opening 411 formed inside. A first ventilation hole 414 is arranged on the surface of the handle ring 410. The passenger can hold the handle ring 410 and achieve a stable grip through the handrail opening 411. At the same time, the first ventilation hole 414 is located on the surface of the handle ring 410 and can blow directly to the palm of the passenger to ensure the passenger's gripping experience.

[0045] It should be noted here that the handle 400 can be set to be in the normal state of the adjacent Figure 2 The inclined state shown in the figure ensures that it is in a closed state under normal circumstances. During the holding process, the passenger holds the handle 400 and pulls it to deflect downward. At this time, the elastic effect of the second torsion elastic component 230 can be overcome, so that the first control opening 221 is in a ventilation state, thereby realizing adaptive conduction and ventilation. At the same time, through the above design, the handle 400 can be placed on the inclined outside to reduce the occupancy of the middle position of the car. At the same time, the staff can judge the internal damage state by the posture of the handle 400 not being affected by external forces, so as to carry out repairs and replacements in time.

[0046] Please refer to the attached Figure 7In order to adjust the size of the ventilation air volume to meet the needs of different passengers; a wind control baffle 222 is slidably arranged on the inner wall of the first control opening 221, and a first hydraulic control component for driving the wind control baffle 222 to move is installed on the inner wall of the first control opening 221, and a second hydraulic control component that is connected to the first hydraulic control component is arranged on the surface of the handle ring 410. The telescopic state of the first hydraulic control component can be adjusted by the second hydraulic control component on the surface of the handle ring 410 to control the extension state of the wind control baffle 222, so as to control the size of the ventilation cross-section of the first control opening 221; for example, the passenger can hold the handle ring 410 tightly to fully compress the second hydraulic control component, so that the first hydraulic control component is in an extended state, so that the wind control baffle 222 closes the first control opening 221, thereby reducing or closing the air volume to meet the needs of the passengers.

[0047] Please refer to the attached Figure 8 , as the first implementation mode of the second hydraulic control component; the second hydraulic control component here includes a plurality of first hydraulic blocks 420, and the plurality of first hydraulic blocks 420 are installed on the inner wall of the handle ring 410 and arranged at intervals along the edge of the handle ring 410. The passenger can squeeze different numbers of first hydraulic blocks 420 according to the width of the grip, and then adjust the squeezing state of the second hydraulic control component to achieve adaptive hydraulic control.

[0048] Please refer to the attached Fig. 9 , as a second implementation manner of the second hydraulic control component; the second hydraulic control component includes a second hydraulic block 430, and the second hydraulic block 430 is installed on the bottom surface of the handle ring 410. The passenger can adjust the squeezing state of the second hydraulic block 430 by squeezing the second hydraulic block 430 with the thumb to meet the overall squeezing requirements, thereby realizing linear adjustment of the first hydraulic control component and meeting the passenger's grip ventilation requirements.

[0049] Specific reference is made to the appendage 3, the handle 400 here also includes an installation workpiece 412 and a hollow installation sleeve 413, the installation sleeve 413 is used to fix the installation workpiece 412 and the first armrest assembly 200, the installation workpiece 412 here is hollow and can allow ventilation conveying pipes and hydraulic conveying pipes to pass through, so as to realize the transportation of ventilation medium and control medium; the ventilation conveying pipe here is for pumping dry gas in the ventilation pipe 100 to the first ventilation hole 414, and the hydraulic pipe is used to connect the first hydraulic control assembly and the second hydraulic control assembly to realize stable pumping of the medium; through the above structure, the handle ring 410 can be conveniently installed at the lower end of the first armrest assembly 200.

[0050] A method for installing a combined handrail in a rail transit carriage comprises the following steps:

[0051] S1. Pass the first armrest assembly 200 and the second armrest assembly 300 through the ventilation duct 100 and sleeve them on the surface of the ventilation duct 100; insert the second armrest assembly 300 into the edge of the first armrest assembly 200, and the first armrest assembly 200 and the second armrest assembly 300 can rotate as a single body.

[0052] S2. Control the first ventilation opening 110 on the inner wall of the first armrest assembly 200 to correspond to the first control opening 221, control the second ventilation opening 120 on the inner wall of the second armrest assembly 300 to correspond to the second control opening 312, and limit and fix the first armrest assembly 200 and the second armrest assembly 300 from both sides; by controlling the corresponding ventilation openings to be relative to the corresponding control openings, it is ensured that the first armrest assembly 200 and the second armrest assembly 300 can allow the gas in the ventilation duct 100 to pass through after rotation, so as to achieve drying of the palms of the passengers; the alternating combination installation method of the first armrest assembly 200 and the second armrest assembly 300 has a stable overall structure, a long service life of the overall structure, and a precise and stable ventilation effect.
