In an embodiment, a portion of the sill 110 cooperating with the door body 120 is defined as a sill 110 unit, and dust collecting members 140 are disposed at both ends of each sill 110 unit. Specifically, if two door bodies 120 are included in the elevator door assembly 100, the sill 110 unit refers to a portion cooperating with a single door body 120. By arranging the dust collecting members 140 at both ends of each sill 110 unit, the sundries in the groove 112 can be cleaned into the dust collecting members 140 no matter the door 120 performs the opening or closing action, so that the groove 112 has a better cleaning effect.
Referring to fig. 3 and 4, in an embodiment, the cleaning element 130 includes a first cleaning element 131 and a second cleaning element 132, and the first cleaning element 131 and the second cleaning element 130 are distributed on two opposite sides of the door 120. Specifically, taking the elevator door assembly 100 installed in the elevator system 10 and the door 120 performing opening and starting as an example, the door 120 has a starting position for completely closing the outer doorway 220 and an ending position for completely opening the outer doorway 220 relative to the groove 112, correspondingly, when the door 120 is located at the starting position, the first cleaning element 131 has a first position relative to the sill 110, the second cleaning element 130 has a second position relative to the sill 110, and the first cleaning element 131, the second cleaning element 130 and the dust collecting element 140 are sequentially arranged along the length direction of the groove 112.

Through the door 120 performing the opening operation at least twice, the sundries in the groove 112 can be completely cleaned to the collection chamber 141. Of course, the door 120 may perform the opening operation for a plurality of times, so that the groove 112 has a better cleaning effect. When the door 120 performs a closing operation, the door 120 slides from the end position to the start position, and the first cleaning member 131 and the second cleaning member 130 slide to the corresponding first position and second position, respectively. The first cleaning element 131 and the second cleaning element 130 are respectively disposed on two opposite sides of the door 120, and in the process of opening or closing the door 120, the first cleaning element 131 and the second cleaning element 130 can clean the whole area through which the door 120 slides, so that the groove 112 has a better cleaning effect.
Alternatively, the first cleaning element 131 and the second cleaning element 130 may be fixedly connected or detachably connected with the door body 120, and in an embodiment, both the first cleaning element 131 and the second cleaning element 130 are detachably connected with the door body 120. Therefore, when the first cleaning member 131 and the second cleaning member 130 have poor cleaning effects due to wear, the first cleaning member 131 and the second cleaning member 130 can be detached and replaced, so that the elevator door assembly 100 can always maintain a better cleaning effect. Specifically, the first cleaning element 131 and the second cleaning element 130 may be detachably mounted on the door 120 by bolts, pins, or clips.

The convex hull 133 prevents impurities from adhering to the surface of the cleaning element 130, so that the groove 112 has a better cleaning effect. Specifically, in the process that the cleaning element 130 slides along with the door 120, the sundries contacting with the surface of the convex hull 133 of the cleaning element 130 continuously generate micro-vibration in the process of being pushed by the cleaning element 130, and the vibration amplitude is perpendicular to the sliding direction of the cleaning element 130, and further, the sundries continuously receive the alternating action of the vibration force in the positive and negative directions perpendicular to the sliding direction to generate positive and negative bending micro-deformation, so that the sundries are not easily adhered to the cleaning element 130, and thus, the cleaning efficiency of the cleaning element 130 can be further improved.
Referring to fig. 5 and fig. 6, in an embodiment, the elevator door assembly 100 further includes a cover 150 and an abutting member disposed in the hoistway 200, the cover 150 covers the opening of the collecting cavity 141 and is rotatably connected to the dust collecting member 140, the cleaning member 130 is rotatably connected to the door 120, when the door 120 performs an opening or closing action, the cleaning member 130 slides to an extreme position and abuts against the abutting member 160 to drive the abutting member 160 to slide along the sliding direction of the cleaning member 130, the abutting member 160 slides to drive the cover 150 to turn over relative to the dust collecting member 140, and the opening of the collecting cavity 141 is opened; under the reaction force of the abutting piece 160, the cleaning piece 130 rotates relative to the door body 120, and the cleaning part 135 of the cleaning piece 130 in the groove 112 provides a driving force for cleaning the impurities into the collecting cavity 141 along the direction towards the dust collecting piece 140.
Normally, the cover 150 covers the opening of the collecting chamber 141 to seal the collecting chamber 141, so as to prevent the odor generated by the retention of the impurities in the collecting chamber 141 from diffusing into the hoistway 200. When the door 120 performs an opening or closing action, specifically, taking the door 120 performs an opening or a closing action as an example, when the door 120 is located at an initial position, the cleaning piece 130 has an initial position relative to the groove 112, when the door 120 is located at a final position, the cleaning piece 130 has a limit position relative to the groove 112, it is defined that a sliding direction in which the cleaning piece 130 slides from the initial position to the limit position is a first direction, a sliding direction in which the cleaning piece 130 slides from the limit position to the initial position is a second direction, when the cleaning piece 130 slides to the limit position along the first direction, a pushing force is applied to the abutting piece 160, the pushing force drives the abutting piece 160 to slide along the first direction, and then the cover 150 is driven to rotate relative to the dust collecting piece 140, and an opening of the collecting cavity 141 is; meanwhile, the abutting member 160 applies a reaction force to the cleaning member 130 along the second direction, the cleaning member 130 rotates relative to the door 120 under the action of the reaction force, and the impurities are cleaned into the collecting cavity 141 along the first direction. Therefore, by providing the abutting member 160 and the cover 150, not only the odor in the collecting cavity 141 can be prevented from diffusing, but also the cover 150 can be automatically opened when the sundries need to be collected, and the sundries can be automatically cleaned into the collecting cavity 141 by the cleaning member 130, so that the elevator door assembly 100 has better cleaning efficiency.
Further, in one embodiment, the cleaning element 130 and the abutting element 160 are both elastic. Specifically, the cleaning element 130 has an operation portion 134 that protrudes out of the groove 112 and faces the cleaning portion 135, and the contact member 160 has a contact portion 161, and when the cleaning element 130 slides to the limit position, the operation portion 134 comes into contact with the contact portion 161. The contact parts of the cleaning element 130 and the contact element 160 are all elastic structures, so that when the cleaning element 130 slides to the limit position along the first direction, in the process of contacting the contact part 161 and the operation part 134, the impact between the contact part 161 and the operation part 134 can be reduced, and the service lives of the cleaning element 130 and the contact element 160 can be prolonged conveniently.

The third section 1616 is disposed through the mounting hole 210 to enable the abutment 160 to be mounted on the inner wall of the hoistway 200. The radial dimension of the first section 1612 and the second section 1614 in the mounting hole 210 is larger than the diameter of the mounting hole 210, so that the third section 1616 can be ensured to be always inserted into the mounting hole 210 in the sliding process of the abutting member 160, and the abutting member 160 is prevented from being mounted and failed.
In one embodiment, the elevator door assembly 100 further includes a restoring member 170, the restoring member 170 providing a restoring force that drives the restoring of the abutment member 160. Specifically, when the abutting member 160 is not in contact with the cleaning member 130, the abutting member 160 is located at the limit position, the cleaning member 130 slides to the limit position to push the abutting member 160 away, and the restoring member 170 provides a restoring force to the abutting member 160, wherein the restoring force slides towards the limit position. In this way, when the cleaning member 130 slides in the second direction to return to the initial position and the restoring force is larger than the acting force of the cleaning member 130 on the abutment member 160, the abutment member 160 automatically slides in the second direction to return to the limit position under the driving of the restoring force to wait for the next abutment of the cleaning member 130. At the same time, the cover 150 is rotated in the opposite direction and covers the opening of the collection chamber 141 again, so that the collection chamber 141 is closed again. Therefore, by providing the reset member 170, the abutting member 160 and the cover 150 can be automatically reset, so that the operation of the whole elevator assembly is easier.
Further, in one embodiment, the reset element 170 is a sleeve spring, which is sleeved on the third section 1616 and abuts against the inner wall of the hoistway 200 and the first section 1612. By providing the wrap spring, the difficulty of mounting the reset member 170 can be reduced, so that the reset member 170 has better mounting convenience. In addition, the set spring is sleeved on the third section 1616, and the third section 1616 can guide the set spring in the compression or resetting process of the set spring, so that the movement of the set spring is more stable, the fluctuation of the resetting force applied to the abutting part 160 is smaller, and the abutting part 160 can be reset through stable sliding.
In an embodiment, an elastic member (not shown) may be disposed between the cleaning member 130 and the door 120, defining that the cleaning member 130 has a predetermined state when not abutting against the abutting member 160, the state where the cleaning member 130 abuts against the abutting member 160 and rotates under the action of the abutting member 160 is the cleaning state, and the elastic member provides an elastic force for the cleaning member 130 to drive the cleaning member 130 to switch from the cleaning state to the predetermined state. Specifically, when the cleaning element 130 is gradually separated from the abutting element 160, the elastic element drives the cleaning element 130 to rotate in the opposite direction, the cleaning element 130 is switched to a pending state, and then the cleaning element 130 is separated from the elastic element and slides in the second direction to wait for the next abutting with the abutting element 160. By providing the elastic member, the cleaning member 130 can be automatically switched between the pending state and the cleaning state, so as to improve the cleaning efficiency of the elevator door assembly 100.

Specifically, the abutting member 160 further includes a connecting portion 162 and a rolling portion 163, one end of the connecting portion 162 is connected to a side of the second segment 1614 opposite to the third segment 1616, and the rolling portion 163 is mounted at an end of the connecting portion 162 far from the second segment 1614 and is rotatable relative to the connecting portion 162. Alternatively, the rolling part 163 may be a roller, a ball, or the like, and the rolling part 163 abuts against the surface of the transmission part 152 and rolls on the surface of the transmission part 152 during the sliding process of the abutting part 160 along the first direction or the second direction, so as to drive the transmission part 152 to drive the covering part 151 to rotate relative to the dust collecting part 140. By providing the rolling part 163, the frictional resistance of the abutting piece 160 and the cover 150 during relative movement can be reduced, so that the abrasion of the abutting piece 160 and the cover 150 is small, and the service life of the elevator door assembly 100 is prolonged.
