[0037] A limit block 117 and a spring pressure block 118 are fixedly provided on the surface of the water tank body 109. The limit block 117 and the spring pressure block 118 are respectively located at two sides of the driving rod body 115. A compression spring 119 is provided in the spring pressure block 118.

A pushing protrusion 122 is fixedly provided on the relay wheel 121. When the relay wheel 121 rotates, the driving rod body 115 is squeezed and driven by the pushing protrusion 122, so that the driving rod body 115 compresses the compression spring 119.

[0038] An integrated gear ring 123 is coaxially fixed on the relay wheel 121, and a driving pinion 124 is meshed on the outside of the integrated gear ring 123. A motor module 125 is fixed on the bottom of the water tank body 109, and the motor module 125 is transmission-installed with the driving pinion 124. The integrated gear ring 123 is driven to rotate by driving the driving pinion 124. A sewage pipe 126 is connected to the bottom of the water tank body 109, and the sewage pipe 126 is connected to the sewage tank in the vehicle, or directly discharged from the bottom of the vehicle.

[0039] A secondary chamber 201 is provided inside the light-guiding filling glue 2, and a floating piston 202 is provided inside the secondary chamber 201. The floating piston 202 is in sliding and airtight contact with the inner wall surface of the secondary chamber 201. A counterweight platform 203 is fixedly provided on the upper part of the floating piston 202, and a floating spring 204 is provided on the lower part of the floating piston 202. The floating piston 202 is elastically supported by the floating spring 204.

[0040] A pressure equalizing air hole 205 is formed through the inner wall surface of the secondary chamber 201 near the upper part, and a breathing air hole 206 is formed through the bottom of the secondary chamber 201. The breathing air hole 206 is connected to the inner cavity of the water tank body 109. Fig.10As shown in , when the floating piston 202 moves up and down, the air pressure above the floating piston 202 is balanced through the pressure equalizing hole 205 to prevent the air pressure from affecting the up and down movement of the floating piston 202.

[0041] The integrated handrail of the present invention is connected to the cleaning liquid tank through a water pump when in use, and the water pump can input cleaning liquid into the liquid inlet pipe 108. The upper and lower ends of the handrail are fixed at the top and bottom of the carriage through the upper mounting plate 103 and the water tank body 109, so that the handrail tube body 1 is in a vertical state.

[0042] The carbon fiber heating wire 3 is energized to generate heat, which heats the handrail tube body 1 and maintains the temperature at about 40°C, making it more comfortable for passengers to grasp. The bright-light bead 5 is energized, and the light-guiding filling glue 2 conducts the light emitted by the bright-light bead 5 and displays it through the prompt groove 4, so that the handrail is integrated with the prompt luminous display function, which improves the aesthetics and increases the visibility of the prompt.

[0043] When the vehicle arrives at the terminal and all passengers have gotten off, Figure 8 As shown in , the cleaning liquid is input through the liquid inlet pipe 108, and the cleaning liquid is evenly distributed in the flow-equalizing ring bin 104, and then falls through the evenly distributed flow holes 107, and the flow is guided by the constriction ring eaves 106, so that the cleaning liquid adheres to the surface of the handrail tube body 1, and flows from top to bottom along the surface of the handrail tube body 1, thereby flushing and cleaning the surface of the handrail tube body 1; as shown in Fig.10 As shown in FIG. 1 , the waste liquid will flow into the water tank body 109 through the drainage screen hole 111 and finally be discharged through the sewage pipe 126 .

[0044] In the above process, the motor module 125 drives the driving pinion 124 to rotate, and the driving pinion 124 drives the integrated gear ring 123 and the relay wheel 121 to rotate. Figure 6 As shown in FIG. 1 , the relay wheel 121 is Figure 6 The middle angle is clockwise rotation. During the rotation of the relay wheel 121, the pushing protrusion 122 squeezes the driving rod 115, so that the driving rod 115 elastically compresses the compression spring 119. After the pushing protrusion 122 passes through the driving rod 115, the driving rod 115 elastically resets, and the cycle continues, so that the driving rod 115 exhibits high-frequency swing. Fig.10 As shown in the figure, the back and forth swinging of the driving rod body 115 drives the handrail tube body 1 to rotate and vibrate in a circle, so that a relative displacement of a horizontal angle occurs between the handrail tube body 1 and the falling cleaning liquid, which can reduce the blind corner area of ​​the cleaning liquid and improve the cleaning effect.

[0045] like Fig.10As shown in the figure, during the bumpy driving of the vehicle, the floating piston 202, with the cooperation of the counterweight platform 203 and the floating spring 204, will move up and down relative to the secondary chamber 201 as the vehicle bumps and shakes. When the floating piston 202 moves down, the breathing hole 206 sprays air flow, and when the floating piston 202 moves up, the breathing hole 206 inhales air flow. The breathing of the breathing hole 206 accelerates the flow of air inside the water tank body 109, accelerates the drying speed inside the water tank body 109, reduces the humidity time inside the water tank body 109, and reduces the growth of bacteria.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
