The top of the housing 1 is provided with a disinfectant dropping bottle 28, and a liquid outlet of the disinfectant dropping bottle 28 is arranged on the top of the cleaning block 26 fixed on the second arc-shaped fixing surface 25. The cleaning block 26 and the water absorption block 27 adopted in the embodiment are all common cleaning materials similar to sponge in the market, so the water absorption is good. The water absorption capacity of the water absorption block 27 can absorb the capacity of 8-10 disinfectant dropping bottles 28, and the adopted disinfectant dropping bottles 28 can completely drain the liquid in the bottles in a dropping state for 24 hours, so that the dropped disinfectant can be absorbed by the water absorption block 27 during cleaning. Therefore, people only need to replace the disinfectant dropping bottle 28 and the water absorption block 27 at fixed time.

The specific using process is as follows:

referring to fig. 5 to 6, in this state, the armrest is set on the armrest frame 6 and is not gripped by the passenger. The first grip 2 and the second grip 3 of the arm rest frame 4 are both located at their initial positions. The driving wheel 17 of the turning part is positioned at the top of the sliding cavity 22, and the supports of the driving wheel 17, the driven gear 20 and the free gear 19 are meshed and connected through the synchronous rack 18.

Referring to fig. 7 to 8, when a passenger grasps the second grip 3 on the armrest frame 4, the passenger applies a downward pulling force to the second grip 3, so that the armrest frame 4 moves downward in the sliding through hole 10, on one hand, the sliding head 14 on the frame shaft 12 slides downward in the sliding groove 13 to stabilize the armrest frame 4, and on the other hand, the driving wheel 17 in the turnover part is driven by the fixing sleeve 11 fixed or integrated with the armrest frame 4 to move in the sliding cavity 22 to the bottom of the sliding cavity 22 in the direction of V1 in fig. 8. Because the driving wheel 17, the driven gear 20 and the idler gear 19 are meshed and connected through the synchronous rack 18, the driving wheel 17 drives the synchronous rack 18 to rotate in the direction of V3 in fig. 8 in the process of moving downwards, and therefore the driven gear 20 and the idler gear 19 are respectively driven to rotate in the directions of V4 and V2 in fig. 8. The driven gear 20 is required to overcome the elastic force of the torsion spring 21 during the rotation in the direction of V4. When the driving wheel 17 moves to the bottom of the sliding chamber 22 and stops moving, the self-cleaning handrail has the function of stabilizing the body of a passenger like the conventional handrail.

Referring to fig. 9 to 10, when the passenger releases the second grip 3 of the armrest frame 4, the second grip 3 needs to be turned to the initial position of the first grip 2 for sterilization and cleaning. In the process, the second handle 3 loses the original downward pulling force, i.e. the original downward pulling force is not acted on the armrest frame 4, the fixed sleeve 11 and the inner frame shaft 12. Therefore, at this time, the driven gear 20 receives the elastic force of the torsion spring 21 and rotates in the direction of V4 in fig. 10. Because the driving wheel 17, the driven gear 20 and the idler gear 19 are meshed and connected through the synchronous rack 18, the driven gear 20 drives the synchronous rack 18 to rotate in the direction of V3 in fig. 10 during the rotation process, thereby respectively driving the idler gear 19 and the driving wheel 17 to rotate in the directions of V2 and V5 in fig. 10, and simultaneously the driving wheel 17 also moves in the direction of V1 in fig. 10 to the top of the sliding cavity 22 in the sliding cavity 22 during the rotation process. Since the driving wheel 17 is fixedly connected to the fixing sleeve 11, and the fixing sleeve 11 is fixed to or integrally formed with the handle frame 4, when the driving wheel 17 rotates in the direction of V5 in fig. 10, the second grip 3 on the handle frame 4 is turned over to the initial position of the first grip 2, and the first grip 2 which has been cleaned and sterilized is turned over to the initial position of the second grip 3.

Referring to fig. 11 to 12, during the turning process, the driving wheel 17, the driven gear 20, the idler gear 19 and the synchronization rack 18 continue to rotate along V5, V4, V2 and V3 in fig. 12 until the driving wheel 17 slides to the top of the sliding cavity 22 along V1 in fig. 12, at this time, the second grip 3 turns into the cleaning part between the top of the inner frame plate 23 and the top of the handrail cavity 8 for cleaning and disinfection, and the first grip 2 turns to the initial position of the second grip 3 for a new passenger to grasp. Since the first handle 2 and the second handle 3 are both roller structures, when entering the cleaning component, the disinfectant on the cleaning block 26 is brushed on the second handle 3 by the roller for cleaning and disinfection, and then is absorbed by the water absorption block 27, so that no disinfectant remains on the second handle 3.

When the passenger using the first grip 2 loosens the handle, the turning operation is repeated to replace the sterilized second grip 3 with the used first grip 2.

According to the self-cleaning handrail, the pure mechanical structure is adopted to realize that the handle of the handrail is turned over up and down to perform alternate cleaning and disinfection, so that the effect of cleaning one by one is realized, the low carbon and the environment friendliness are realized, the bacterial sensing is further reduced, and the use comfort level and the public health safety degree of a public transport vehicle are improved.
