As used in the description of the present application, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, the present application provides an elevator sill structure 100, in which the elevator sill structure 100 is used to limit an elevator door 201, so as to prevent the elevator door 201 from falling into a hoistway under the action of an external force.

The elevator sill structure 100 includes a sill unit 10 and a first locking member 20, the sill unit 10 is located on an opening/closing path of the elevator door 201, a first mounting hole 11 is formed on the sill unit 10, and the first mounting hole 11 faces the elevator door 201. The first locking member 20 is movably installed in the first installation hole 11, and the first locking member 20 can move along the axial direction of the first installation hole 11 by an external force. When the elevator door 201 is in the door-open state, the first locking member 20 is located in the first mounting hole 11, and the top of the first locking member 20 is flush with the surface of the sill unit 10; when the elevator door 201 is closed, a portion of the first locking member 20 can protrude out of the first mounting hole 11 and the surface of the sill unit 10 to lock the elevator door 201.

As such, by providing the first locking member 20 and opening the first mounting hole 11 on the sill unit 10, when the elevator door 201 is in the door opening/closing state, the first locking member 20 moves in the first mounting hole 11 to lock the elevator door 201 and to be flush with the surface of the sill unit 10. Moreover, the elevator door 201 is prevented from being pushed into the shaft by external force, and simultaneously, the sill groove is also prevented from being formed on the sill unit 10, namely, the surface of the sill unit 10 is smooth, thereby effectively preventing foreign matters from entering, and ensuring smooth and safe operation of the elevator door 201; the elevator fault caused by the fact that the foreign matter falls into the sill groove to cause the door of the elevator to be not closed in place is avoided, maintenance personnel are removed from cleaning and maintaining the sill groove regularly, meanwhile, the phenomenon that the elevator is stopped due to poor door lock contact of the elevator door 201 caused by the fact that the sliding block is blocked in operation is directly avoided, the root cause of the elevator door 201 fault is greatly reduced, and the fault rate of the elevator door 201 is greatly reduced. Besides, the surface of the sill unit 10 has no other structure except the first locking member 20, so that the friction force in the operation process of the elevator door 201 is reduced, and the operation of the elevator door 201 is smoother.

In an embodiment, as shown in fig. 3 to 5, the sill unit 10 includes a sill body 12 and a sill pedal 13, wherein the sill body 12 is provided with a receiving groove 121, and a portion of the sill pedal 13 is installed in the receiving groove 121, and the other portion is located outside the receiving groove 121 for passengers to step on. The first mounting hole 11 is opened on the sill pedal 13. Meanwhile, the part of the sill pedal 13 located outside the accommodating groove 121 is provided with a plane, so that passengers can conveniently step on the floor; and the sill pedal 13 extends in a direction perpendicular to the elevator door 201 to protrude the sill body 12, thereby making up a gap between the car and the elevator door 201 to prevent passengers from stepping on the space, etc. Of course, in other embodiments, the sill pedal 13 may not be provided. At this time, the sill unit 10 includes only the sill body 12, and the first mounting hole 11 is directly opened on the sill body 12.

Preferably, the sill body 12 may be provided as an aluminum material or an aluminum alloy. The sill pedal 13 may be provided with a metal plate such as a steel plate to ensure the structural strength of the sill pedal 13.

As shown in fig. 3, the sill pedal 13 and the sill body 12 may be detachably connected by a snap, or may be connected by welding. In the present embodiment, the sill pedal 13 and the sill body 12 are connected by a snap-fit connection.

With reference to fig. 3, the sill pedal 13 includes a plate 131 and a connecting portion 132, the connecting portion 132 is disposed in the sill body 12, and the first mounting hole 11 penetrates the connecting portion 132. The plate body 131 is located outside the sill body 12 and is connected to the connecting portion 132.

In one embodiment, the shape of the first locking member 20 is adapted to the shape of the first mounting hole 11. For example, when the first mounting hole 11 is a square hole, the cross section of the first locking member 20 is also square; when the first mounting hole 11 is an elliptical hole, the cross section of the first locking member 20 is also elliptical. In the present application, the first mounting hole 11 is a circular hole, that is, the cross section of the first locking member 20 is circular.

The first locking member 20 is provided as a metal member. This is done to ensure the structural strength of the first locking member 20. In the present embodiment, the first locking member 20 is preferably formed by machining a ferromagnetic material, and the first locking member 20 is provided in a cylindrical shape. Therefore, in the processing process, only the corresponding bar needs to be searched for cutting, and the processing is very convenient.

As shown in fig. 6 and 7, a limiting portion 111 is disposed on a hole wall of the first mounting hole 11, an engaging portion 21 is disposed on the first locking element 20, and the limiting portion 111 and the engaging portion 21 can form a limiting engagement to limit a movement stroke of the first locking element 20 in the first mounting hole 11. Therefore, the first locking member 20 can be prevented from being separated from the first mounting hole 11, the first locking member 20 is prevented from being locked and failed, and the locking reliability and the operation stability of the elevator door 201 are improved.

Preferably, the position limiting part 111 is located at one end of the first mounting hole 11 near the elevator door 201, i.e., the first mounting hole 11 is disposed near a surface of the sill unit 10 facing one end of the elevator door 201. The engaging portion 21 is disposed at an end of the first locking member 20 away from the elevator door 201. Thus, when the first locking member 20 is in the original state (the state of not locking the elevator door 201), along the axial direction of the first mounting hole 11, the distance between the limiting portion 111 and the engaging portion 21 is the stroke of the first locking member 20 capable of moving in the first mounting hole 11, or the length of the first locking member 20 capable of extending out of the first mounting hole 11.

In an embodiment, the position-limiting portion 111 may be a protrusion disposed on the hole wall of the first mounting hole 11. The stopper 111 may be a protrusion provided on an outer wall of the first locking member 20. The protrusion on the hole wall of the first mounting hole 11 and the protrusion on the outer wall of the first locking member 20 cooperate with each other to limit the moving stroke of the first locking member 20 in the first mounting hole 11.

In another embodiment, as shown in fig. 6 and 7, the first mounting hole 11 includes a first hole 112 and a second hole 113 communicating with each other, and the first hole 112 has a larger hole diameter than the second hole 113, such that the first mounting hole 11 is configured as a stepped hole, thereby forming a stopper portion 111 between the first hole 112 and the second hole 113. The first locking member 20 comprises a first rod 22 and a second rod 23, the first rod 22 being located within the first aperture 112, the second rod 23 being capable of extending through the first aperture 112 into the second aperture 113; wherein the first rod 22 has a diameter larger than that of the second rod 23 to form a fitting portion 21 between the first rod 22 and the second rod 23.

The above two are only schematic illustrations of the structures of the limiting portion 111 and the engaging portion 21. In other embodiments, the limiting parts 111 and the matching parts 21 can be configured in other structures as long as the limiting of the first locking element 20 is achieved, and the structure is not exhaustive here.

As shown in fig. 8, the number of the first mounting holes 11 is set to be plural along the extending direction (i.e., the length direction) of the sill unit 10, and the plural first mounting holes 11 are spaced apart from each other. One first locking member 20 is disposed in each first mounting hole 11, so that when the elevator door 201 is in a closed state, a plurality of first locking members 20 simultaneously lock the elevator door 201, thereby improving the stability of locking the elevator door 201 and the safety of operation.

As shown in fig. 1, 2 and 8, the sill unit 10 includes an open door region 14 and a non-open door region 15, and the open door region 14 and the non-open door region 15. When the elevator door 201 is located in the door opening area 14, the elevator door 201 is in a door closing state, and when the elevator door 201 is located in the door non-opening area 15, the elevator door 201 is in a door opening state. The first locking member 20 is located in the door opening area 14 area so that when the elevator door 201 is located in the door opening area 14, the first locking member 20 can protrude out of the first mounting hole 11, thereby locking the elevator door 201. When the elevator door 201 is located in the non-door-opening area 15, the first locking member 20 falls into the first mounting hole 11 by gravity, and the top of the first locking member 20 is flush with the surface of the sill unit 10.

In an embodiment, the elevator sill structure 100 further includes a second locking member 30, the second locking member 30 is located in the non-door-opening region 15, and the second locking member 30 always protrudes out of the surface of the sill unit 10, so as to lock or limit the elevator door 201 when the elevator door 201 is located in the non-door-opening region 15, thereby preventing the elevator door 201 from falling to the hoistway in the non-door-opening region 15 due to an external force.

It should be explained that the sill unit 10 is installed at an elevator entrance at each floor. Along the length direction of the sill unit 10, the door-opening region 14 corresponds to the doorway, and the other portions of the sill unit 10 are the non-door-opening regions 15. The door-opening region 14 is located at a middle position of the sill unit 10, and the non-door-opening region 15 is disposed at a side of the door-opening region 14.

As shown in fig. 4, the sill unit 10 is provided with a second mounting hole 16, the second mounting hole 16 is located in the non-door-opening region 15, one end of the second locking member 30 is fixed in the second mounting hole 16, and the other end thereof protrudes out of the second mounting hole 16 and protrudes out of the surface of the sill unit 10. So that part of the second locking member 30 can always extend out of the second mounting hole 16 and cooperate with the elevator door 201 to achieve the locking of the elevator door 201 at the non-door-opening region 15.

Specifically, the second mounting hole 16 is opened on the sill pedal 13, and the second locking member 30 protrudes from the surface of the sill pedal 13, so that a lock or a limit for locking the elevator door 201 is formed on the surface of the sill pedal 13 in the non-door opening region 15.

It should be noted that, at the non-door-opening region 15, the second locking member 30 itself protrudes out of the second mounting hole 16, so that the external force can be interpreted as the force applied when the second locking member 30 is mounted. The length of the first locking member 20 located in the door opening area 14 is shorter than that of the second locking member 30 located in the door non-opening area 15, when the elevator door 201 is in the door opening state (i.e. the elevator door 201 is located in the door non-opening area 15), the first locking member 20 is accommodated in the first mounting hole 11, and when the elevator door 201 is in the door closing state (i.e. the elevator door 201 is located in the door opening area 14), a part of the first locking member 20 can extend out of the first mounting hole 11 under the action of external force, so as to cooperate with the elevator door 201 and lock or limit the elevator door 201, so as to prevent the elevator door 201 from falling to the hoistway under the action of external force.

Specifically, the second locking member 30 includes a third rod 31 and a fourth rod 32, the third rod 31 is located in the second mounting hole 16 and is limited in the second mounting hole 16, and the fourth rod 32 protrudes from the second mounting hole 16 and protrudes from the surface of the sill pedal 13.

Further, the fitting relationship between the second locking member 30 and the second mounting hole 16 can be referred to as the fitting relationship between the first locking member 20 and the first mounting hole 11. The difference between the two is that the second locking member 30 cannot move in the second mounting hole 16, and is directly positioned in the second mounting hole 16, and cannot move up and down along the axis of the second mounting hole 16; the first locking member 20 can move up and down in the first mounting hole 11.

As shown in fig. 8, the number of the second mounting holes 16 is set to be plural along the extending direction (i.e., the length direction) of the sill unit 10, and the plural second mounting holes 16 are spaced apart from each other. One second locking member 30 is disposed in each second mounting hole 16, so that when the elevator door 201 is in an open state, a plurality of second locking members 30 simultaneously lock the elevator door 201, thereby improving the stability of locking the elevator door 201 and the safety of operation.

Further, the second mounting hole 16 is located on the same straight line with the first mounting hole 11. In this manner, movement and locking of the elevator door 201 is facilitated.

As shown in fig. 1 and 2, the present application also provides an elevator door assembly 200, the elevator door assembly 200 including an elevator door unit 210 and an elevator sill structure 100; the elevator door unit 210 is provided with a matching groove 211 towards one end of the elevator sill structure 100, and the matching groove 211 is used for the first locking member 20 to extend into, so that the first locking member 20 locks the elevator door unit 210 when the elevator door unit 210 is in a closed state.

In one embodiment, as shown in fig. 3, 4 and 9, the elevator door unit 210 includes an elevator door 201 and a door panel 202, wherein the door panel 202 is installed at one end of the elevator door 201 close to the elevator sill structure 100; wherein, the matching groove 211 is arranged on the door panel 202. It can be understood that the structural strength of the portion where the elevator door 201 is engaged with the first locking member 20 is locally reinforced by providing the door panel 202. Of course, the door panel 202 can be omitted without considering the above situation, and the engagement groove 211 is directly opened on the elevator door 201, i.e. the first locking member 20 is directly engaged with the elevator door 201 in a limiting manner.

As shown in fig. 3 and 4, the elevator door assembly 200 further includes a magnetic member 230, and the magnetic member 230 is installed in the fitting groove 211 to magnetically attract the first locking member 20 such that the first locking member 20 protrudes out of the first installation hole 11 and into the fitting groove 211. As such, the magnetic member 230 acts as a driving member to provide a force for the movement of the first locking member 20. The movement of the first locking member 20 is controlled by the magnetic member 230 magnetically attracting the first locking member 20, which effectively ensures that the first locking member 20 can normally lock the elevator door 201; on the other hand, the magnetic force is adopted, so that almost no noise exists in the running process of the elevator door 201.

In one embodiment, the magnetic member 230 is configured to be strong magnetic, and the first locking member 20 is configured to be a ferromagnetic material, such as a magnet or an iron rod, which can be attracted by the magnetic member 230. Accordingly, when the elevator door 201 travels to the door opening region 14, the first locking member 20 is protruded out of the first mounting hole 11 and into the fitting groove 211 by the attraction of the magnetic member 230.

The magnetic member 230 may also be provided as an electromagnet, i.e., a magnetic field is generated when power is applied to attract the first locking member. It is understood that when the magnetic member 230 is configured as an electromagnet, the first locking member 20 can be configured to be movable in both the door opening region 14 and the door non-opening region 15. Thus, the first locking member 20 is turned on and off to achieve the movement in each region.

Of course, in the present application, the magnetic member 230 is correspondingly disposed only at a place where the fitting groove 211 corresponds to the door opening area 14. At this time, when the magnetic member 230 moves to the door opening region 14 along with the elevator door 201, the magnetic member 230 attracts the first locking member 20 located at the door opening region 14, so that the first locking member 20 protrudes out of the first mounting hole. When the magnetic member 230 moves to the non-door-opening area 15 along with the elevator door 201, the first locking member 20 in the door-opening area 14 loses the attraction force of the magnetic member 230, so that the first locking member 20 falls back into the first mounting hole 11 under the action of its own gravity, so that no other component exists in the door-opening area 14.

Preferably, the magnetic member 230 is adhered in the fitting groove 211 by a glue. Thus, the magnetic member 230 is conveniently and simply installed. Of course, in other embodiments, the magnetic member 230 may be fixed in the matching slot 211 by means of screws, snaps, or the like.

In one embodiment, the engagement slot 211 extends along the traveling direction of the elevator door 201, and the length of the extension can cover the door opening region 14 and the door non-opening region 15. Therefore, when the elevator door 201 moves to the non-door-opening area 15, the second locking member 30 located at the non-door-opening area 15 naturally enters the engaging groove 211 and forms a limit engagement with the engaging groove 211, so as to prevent the elevator door 201 from being dumped into the hoistway by external force in the non-door-opening area 15.

In the present application, it should be noted that the magnetic member 230 is used as a driving member to drive the first locking member 20 to move, and is only one of the modes of the first locking member 20 to move. For example, the movement of the first locking member 20 can also be realized by other means such as an air cylinder, a push rod, etc., which are not described herein, as long as the first locking member 20 can be driven to move and lock the elevator door 201.

The working process of the application is as follows:

when the elevator door 201 travels to the door opening area 14, the elevator door 201 is in a door closed state. At this time, the first locking member 20 located at the door opening region 14 extends out of the first mounting hole 11 and into the fitting groove 211 under the attraction of the magnetic member 230, so as to lock or limit the elevator door 201, and prevent the elevator door 201 from being dumped into the hoistway under the action of external force.

When elevator door 201 travels to non-door-opening area 15, elevator door 201 is in a door-open state. At this time, the first locking member 20 located at the door opening region 14 loses the adsorption force of the magnetic member 230 and falls back into the first mounting hole 11 under the action of its own gravity, so that the sill unit 10 is prevented from having no sill groove and other impurities; at the same time, the second locking member 30 located at the non-door-opening area 15 also enters the engagement groove 211, thereby preventing the elevator door 201 from being forced into the hoistway at the non-door-opening area 15.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
