Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. Embodiments and features of embodiments in this application may be combined with each other without conflict. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 12, the present utility model provides an automatic cleaning device for an elevator car, comprising: a first shell 2 arranged on the car wall opposite to the car door in the car 1 and a second shell 3 arranged at two ends of the first shell 2 and clung to the car walls at two sides of the car 1;

a brush roller 4 disposed in the first casing 2 for cleaning the bottom of the car;

and the driving assembly 5 is arranged in the second shell 3 and connected with the brush roller 4 and is used for driving the brush roller 4 to clean the car bottom.

When the elevator is in an idle state, the elevator central processing unit starts the driving assembly 5, the driving assembly 5 drives the brush roller 4 to move out of the first shell 2, the brush roller moves towards the direction of the car door along the second shell 3 and rotates around the axis of the brush roller, and when the brush roller 4 moves to be close to the car door, the driving assembly 5 drives the brush roller to do return motion, and the cleaning of the car 1 is realized in the back and forth motion of the brush roller 4.

In one embodiment, the driving assembly 5 includes a moving assembly 51 provided in the second housing 3 for driving the brush roller 4 to make a linear motion, and a rotating assembly 52 provided on the moving assembly 51 for driving the brush roller 4 to rotate. By the design, the brush roller 4 can be driven to linearly move along the direction of the second shell 3 through the moving component 51, and the brush roller 4 is driven to rotate along the axis of the brush roller 4 through the rotating component 52, so that the cleaning combined movement of the brush roller 4 driven by the driving component 5 is realized.

In one embodiment, the moving assembly 51 includes a first stepping motor 512 disposed at one end inside the second housing 3, a screw 511 having one end connected to an output end of the first stepping motor 512 and the other end rotatably disposed at one end of the second housing 3 remote from the first stepping motor 512, and a screw 513 disposed on the screw 511 and connected to the brush roller 4. In this way, the first stepper motor 512 can drive the screw rod 511 to rotate, the screw rod 511 drives the screw nut 513 to do linear motion along the screw rod 511, so that the brush roller 4 connected with the screw nut 513 is driven to do linear motion along the screw rod 511, in addition, the distance movement of the brush roller 4 can be achieved by presetting the single rotation number of turns of the first stepper motor 512 according to the distance between the initial state of the brush roller 4 and the car door, and the reciprocating motion of the brush roller 4 can be achieved by controlling the forward and reverse rotation of the first stepper motor 512, so that the reciprocating motion of the brush roller 4 in the car 1 at a fixed distance can be achieved.

In one embodiment, the rotating assembly 52 includes a second stepping motor 521 disposed at the top of the screw 513, a first gear 522 disposed on an output shaft of the second stepping motor 521, a connection assembly 524 having one end connected to the brush roller 4 and the other end rotatably disposed on the screw 513, and a second gear 523 fixedly disposed on the connection assembly 524 and engaged with the first gear 522. In this way, the second stepping motor 521 drives the first gear 522 to rotate, the first gear 522 drives the second gear 523 to rotate, the second gear 523 drives the connecting component 524 to rotate, and finally the connecting component 524 drives the brush roller 4 connected with the connecting component to rotate.

In one embodiment, the connection assembly 524 includes a connection shaft 5241 rotatably provided to the screw 513, a socket 5242 provided at one end of the connection shaft 5241, and elastic plugs 5243 provided at both ends of the brush roller 4 and engaged with the socket 5242. When the brush roller 4 is installed, the top blocks of the elastic plugs 5243 at the two ends of the brush roller 4 are pressed into the grooves, the elastic plugs 5243 are aligned with the insertion holes 5242, the elastic plugs 5243 are released, and the top blocks of the elastic plugs 5243 are inserted into the insertion holes 5242, so that the installation of the brush roller 4 is completed, and the installation operation steps are simplified.

In an embodiment, a protective door 6 is hinged to one side of the first casing 2 close to the car door, and an electric telescopic rod 7 with one end hinged to the protective door 6 and the other end hinged to the inner wall of the first casing 2 is arranged in the first casing 2. By means of the design, the protective door 6 can be opened and closed through the telescopic movement of the electric telescopic rod 7, so that the brush roller 4 can conveniently enter and exit the first shell 2 in the reciprocating cleaning movement.

In one embodiment, the electric telescopic rod 7 and the driving assembly 5 are electrically connected with the elevator central processor. By means of this design, the motion of the electric telescopic rod 7 and the driving assembly 5 can be controlled by the elevator central processing unit. It should be noted that the control logic of the elevator central processing unit is: when the elevator is in the leisure state for a long time, the elevator central processing unit controls the electric telescopic rod 7 to do extension movement and simultaneously controls the driving component 5 to operate, and when cleaning is finished, the driving component 5 is controlled to stop operating and controls the electric telescopic rod 7 to do contraction movement.

In one embodiment, the top of the first housing 2 is hinged with a mounting door 9. This design facilitates the installation and maintenance of the structure in the first housing 2 by opening the installation door 9.

In an embodiment, the top of the mounting door 9 is provided with a first handle 10. Designed in this way, the door 9 is easily opened and closed by the first handle 10.

In one embodiment, the first housing 2 is provided with a collecting box 8, the mounting door 9 is provided with a mounting groove 11, and the collecting box 8 is provided with a second handle 12 matched with the mounting groove 11. By means of the design, the garbage collection box 8 is convenient to collect cleaned garbage, the collection box 8 is convenient to be installed in and taken out of the first shell 2 by opening the installation door 9, the collection box 8 is convenient to be taken out by arranging the second handle 12 on the collection box 8, and interference between the second handle 12 and the installation door 9 in the process of closing the installation door 9 after the collection box 8 is installed in the first shell 2 is avoided by arranging the installation groove 11 on the installation door 9.
