[0031] An embodiment of the present disclosure provides a vibration reduction device for an elevator car system, the elevator car system comprising a car and a car top wheel guide wheel frame. The vibration reduction device comprises an extension plate and N vibration reduction units, the extension plate is configured to be connected to the car top wheel guide wheel frame, wherein when the extension plate is connected to the car top wheel guide wheel frame, the surface of the extension plate is perpendicular to the lifting direction of the car. The vibration reduction unit is connected to the end of the extension plate, wherein the vibration reduction unit is configured to be fixed on the car, and N is an integer greater than or equal to 1.

[0032] Figure 1 The exemplary architecture of an elevator car system 100 to which a vibration reduction device can be applied according to an embodiment of the present disclosure is schematically shown. It should be noted that: Figure 1 What is shown is merely an example of an architecture to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0033] like Figure 1 As shown, the elevator car system 100 according to this embodiment may include a car 110, a car top wheel guide wheel frame 120 and a vibration reduction device (not shown). The car 110 may include a car frame 111 and a car body 112. The car frame 111 includes an upper beam 113. The car body 112 is installed inside the car frame 111 and is located in a first direction (such as direction A) of the upper beam 113, and the first direction (such as direction A) is a direction parallel to the descending direction of the car 110. Among them, the vibration reduction device can be located between the upper beam 113 and the car body 112.

[0034] According to the embodiments of the present disclosure, referring to Figure 1The car frame 111 may also include two columns 114 and a bottom beam 115. The upper parts of the two columns 114 may be connected to the upper beam 113, and the lower parts may be connected to the bottom beam 115. Then the car body 112 is installed on the bottom beam 115. When the car top wheel 121 vibrates, the upper beam 113 is first affected by the car top wheel guide wheel frame 120, and then the vibration may be transmitted to the car body 112 through the upper beam 113. It should be known that the car frame 111 may not include the columns 114 and the bottom beam 115, and the car body 112 may be installed inside the car frame 111 by flexibly selecting existing or future technical means.

[0035] According to an embodiment of the present disclosure, the elevator car system 100 may further include a car top wheel 121. The car top wheel 121 may be installed inside the car top wheel guide wheel frame 120. In the related art, when the elevator car system 100 is working, passengers may enter the car body 112 and control it to move in an ascending direction (such as direction B) or a descending direction (such as direction A). First, since the traction rope is wound around the car top wheel 121, the traction machine may be used to drive the car top wheel 121 to move through the traction rope. Then, the car top wheel guide wheel frame 120 drives the car frame 111 to move. Then, the car body 112 moves accordingly. During the movement, affected by the well space and the layout of the traction medium, the traction ropes on both sides of the car top wheel 121 may be subjected to a torsional torque, which forms a torsional excitation on the car top wheel 121, causing torsional vibration, and then the torsional vibration is transmitted to the car top wheel guide wheel frame 120. Since the car top wheel guide wheel frame 120 is connected to the car frame 111, the torsional vibration will be transmitted to the car body 112 through the car frame 111, and even generate large vibration noise, affecting the passenger experience.

[0036] With the elevator car system 100 of the disclosed embodiment, a vibration reduction device may be installed between the upper beam 113 and the car body 112, so that when the car top wheel guide wheel frame 120 generates torsional vibration, the torsional vibration may be absorbed by the vibration reduction device.

[0037] Refer to the following Figure 2A to Figure 4 , the specific structure and working process of the vibration reduction device of the embodiment of the present disclosure are described in detail.

[0038] Figure 2A The connection diagram of the vibration reduction device 210 according to the embodiment of the present disclosure is schematically shown. Figure 2B The schematic diagram of the connection of the vibration reduction device 210 according to another embodiment of the present disclosure is schematically shown, wherein the car top wheel guide wheel frame 220 is an embodiment of the car top wheel guide wheel frame 120, the car frame 230 is an embodiment of the car frame 111, and the upper beam 231 is an embodiment of the upper beam 113. Figure 2B Omitted Figure 2A Structures such as the middle upper beam and the car top wheel guide wheel frame.

[0039] like Figure 2A and Figure 2B As shown, the vibration reduction device 210 can be used in the elevator car system 100, wherein the vibration reduction device 210 includes an extension plate 211 and N vibration reduction units 212, the extension plate 211 is configured to connect to the car top wheel guide wheel frame 220, wherein when the extension plate 211 is connected to the car top wheel guide wheel frame 220, the surface 2111 of the extension plate 211 is perpendicular to the lifting direction of the car (for example, direction A is parallel to the descending direction, and direction B is parallel to the ascending direction). The vibration reduction unit 212 is connected to the end of the extension plate 211, wherein the vibration reduction unit 212 is configured to be fixed on the car 230 (which can be a car frame 230), and N is an integer greater than or equal to 1.

[0040] According to an embodiment of the present disclosure, the vibration reduction unit 212 may be fixedly connected inside the housing 240 and connected to the upper beam 231 via the housing 240, so as to fix the vibration reduction unit 212 on the car.

[0041] According to the embodiments of the present disclosure, the extension plate 211 can be a thin plate in a rectangular, circular, or diamond shape. For example, the middle portion 2112 of the extension plate 211 is connected to the car top wheel guide wheel frame 220, and the torsional excitation transmitted to the extension plate 211 by the car top wheel guide wheel frame 220 changes dynamically with the movement of the elevator car system 100. When the car top wheel guide wheel frame 220 generates torsional vibration (for example, torsional vibration transmitted by the car top wheel), first, the torsional excitation may be transmitted to the extension plate 211 through the connection. Then, the extension plate 211 is affected by the torsional excitation and has a tendency to rotate. Since the end of the extension plate 211 is connected to a vibration reduction unit 212 fixed on the car, the vibration reduction unit 212 will confront the extension plate 211, offsetting the torsional excitation transmitted by the extension plate 211.

[0042] According to an embodiment of the present disclosure, the vibration reduction unit 212 may include a vibration reduction rubber material or an oil pressure damping structure. The vibration reduction rubber material or the oil pressure damping structure has a high damping characteristic. When the vibration reduction unit 212 is subjected to unidirectional dynamic extrusion by the end of the extension plate 211, the damping material inside the vibration reduction unit 212 plays a role in absorbing and dissipating dynamic torsional kinetic energy, thereby reducing the torsional vibration energy directly transmitted to the car frame 230.

[0043] like Figure 2A and 2B As shown, the bottom of the car top wheel guide frame 220 includes at least one connecting column 270, the axis 271 of the connecting column 270 extends along a first direction (such as direction A), and at least one first through hole (not shown) is provided in the upper beam 231, wherein the connecting column 270 is connected to the extension plate 211 through the first through hole, and the extension plate 211 is connected to the upper beam 231.

[0044] According to an embodiment of the present disclosure, the upper beam 231 may be hollow inside, so that the top wheel guide frame 220 is partially disposed inside the upper beam 231, thereby reducing the overall height of the elevator car system 100. At this time, one or more through holes may be disposed at the bottom of the upper beam 231, so that the connecting column 270 passes through the through holes at the bottom of the upper beam 231 and is connected to the extension plate 211.

[0045] like Figure 2A and 2B As shown, the elevator car system 100 further includes a support plate 250 and a vibration-damping pad 260. The support plate 250 is parallel to the extension plate 211, wherein the support plate 250 is connected to a side of the upper beam 231 facing the first direction (such as direction A). The support plate 250 includes at least one second through hole 251, and the connecting column 270 passes through the second through hole 251 and is connected to the extension plate 211, and the axis 252 of the second through hole 251 is parallel to the axis 2311 of the first through hole. The vibration-damping pad 260 is disposed between the support plate 250 and the extension plate 211.

[0046] According to the embodiments of the present disclosure, see Figure 2B The C2 region is an enlarged region of the C1 region, and the outer surface of the connecting column 270 is not in contact with the inner surface of the second through hole 251.

[0047] According to the embodiment of the present disclosure, the connecting column 270 first passes through the first through hole, and then passes through the second through hole 251 until it is connected to the extension plate 211, wherein a corresponding through hole can be set on the extension plate 211, and the connecting column 270 is set as a bolt, and the connecting column 270 is connected to the lower side of the extension plate 211 through a nut, and the axis 2311 of the first through hole can be, for example, perpendicular to the surface 2111 of the extension plate 211. At this time, since the outer surface of the connecting column 270 is not in contact with the inner surface of the first through hole and the second through hole 251. Therefore, when the connecting column 270 is affected by the vibration of the car top wheel guide wheel frame 220, the vibration will not be transmitted to the upper beam 231 and the support plate 250.

[0048] According to the embodiments of the present disclosure, see Figure 1 , Figure 2A and Figure 2B, the top wheel guide frame 220 is connected to the extension plate 211 through the connecting column 270. For example, the two ends of the connecting column 270 can be fixedly connected to the top wheel guide frame 220 and the extension plate 211. Then, when the top wheel guide frame 220 transmits vibration, it will be transmitted to the extension plate 211 through the connecting column 270. On the one hand, when the extension plate 211 receives vibration in the vertical or horizontal translation direction, the vibration in the translation direction can be absorbed by the vibration-damping pad 260. On the basis of the vibration-damping pad 260 as a buffer, the upper beam 231 supported by the support plate 250 will be less affected by the vibration in the translation direction. On the other hand, when the extension plate 211 receives torsional vibration, it can be transmitted to the vibration-damping unit 212 located at the end of the extension plate 211, and the torsional vibration is absorbed by the vibration-damping unit 212, thereby reducing the impact on the upper beam 231.

[0049] By utilizing the vibration reduction device 210 of the embodiment of the present disclosure, the torsional excitation transmitted from the car top wheel guide wheel frame 220 can be absorbed, and the translational and torsional vibrations can be isolated and absorbed under the joint action of the vibration reduction unit 212 and the vibration reduction pad 260, thereby greatly reducing the vibration response of structures such as the upper beam 231 and reducing the structural noise caused by the vibration.

[0050] It should be noted that, in the process of the connecting column 270 passing through the first through hole and the second through hole 251, an adjustment component (such as an adjustment plate) can be set between the vibration damping pad 260 and the support plate 250, between the support plate 250 and the extension plate 211, or between the extension plate 211 and the connecting column 270, and the present disclosure does not make specific limitations on it.

[0051] Figure 3A The structural diagram of the vibration reduction device 210 according to the embodiment of the present disclosure is schematically shown. Figure 3B Schematically shows an embodiment according to the present disclosure Figure 3A View from the middle E direction.

[0052] like Figure 3A and 3B As shown, the vibration reduction device 210 also includes N connecting brackets corresponding to the N vibration reduction units 212, such as connecting brackets 310 and 320, wherein, taking the connecting bracket 310 as an example, the first end 311 of the connecting bracket 310 is connected to the extension plate 211, and the second end 312 of the connecting bracket 310 is connected to the vibration reduction unit 212, wherein the second end 312 is away from the extension plate 211 relative to the first end 311.

[0053] According to the embodiments of the present disclosure, referring to Figure 3A and 3B , the second end 312 is located inside the vibration reduction unit 212 .

[0054] According to the embodiments of the present disclosure, referring to Figure 3A and 3B , N=2, the two vibration-damping units 212 are symmetrically arranged relative to the middle portion 2112 of the extension plate 211 .

[0055] According to an embodiment of the present disclosure, the vibration reduction device 210 is composed of an extension plate 211, a vibration reduction unit 212, and connection brackets 310 and 320. Two connection brackets 310 and 320 can be provided at both ends of the extension plate 211, and the ends of the connection brackets 310 and 320 extend into the vibration reduction unit 212. When dynamic torsion occurs at the connection part of the extension plate 211, the ends of the two connection brackets 310 act on the vibration reduction unit 212 respectively, and the vibration reduction unit 212 is used to absorb torsional vibration.

[0056] The structural diagram of the connecting bracket is described in detail below by taking the connecting bracket 310 as an example.

[0057] Figure 4 The structural diagram of the connecting bracket 310 according to the embodiment of the present disclosure is schematically shown.

[0058] like Figure 4 As shown, according to an embodiment of the present disclosure, the connecting bracket 310 includes a first connecting plate 410 , and the first connecting plate 410 includes a first end 311 and a second end 312 , wherein the first connecting plate 410 is perpendicular to the extension plate 211 .

[0059] According to the embodiments of the present disclosure, referring to Figure 3A , Figure 3B and Figure 4 , the surface 411 of the first connecting plate 410 is perpendicular to the surface 2111 of the extension plate 211. Therefore, when the extension plate 211 receives a torsional excitation such as in the C direction, the extension plate 211 transmits the torsional excitation to the first connecting plate 410 through the second end 312, and the surface 411 of the first connecting plate 410 confronts the inside of the vibration reduction unit 212. This makes the first connecting plate 410 and the vibration reduction unit 212 have a larger contact area, which can improve the vibration reduction effect. It should be noted that the direction of the torsional excitation is not limited to the C direction. When the torsional excitation direction changes, the surface of the first connecting plate 410 that confronts the vibration reduction unit 212 changes accordingly.

[0060] like Figure 4As shown, the connecting bracket 310 may further include M second connecting plates 420 (e.g., second connecting plates 421 and 422) and M oblique ribs 430 (e.g., oblique ribs 431 and 432). The second connecting plate 420 is connected to the first connecting plate 410, wherein the second connecting plate 420 is perpendicular to the first connecting plate 410. The oblique rib 430 is connected to the first connecting plate 410 and the second connecting plate 420, respectively. A triangular space 440 (which may include triangular spaces 441 and 442) is formed between the oblique rib 430, the first connecting plate 410, and the second connecting plate 420, and M is an integer greater than or equal to 1.

[0061] According to an embodiment of the present disclosure, when the two ends of the first connecting plate 410 are respectively connected to the extension plate 211 and the vibration reduction unit 212, and the first connecting plate 410 is perpendicular to the extension plate 211. If the first connecting plate 410 is a thin plate, the force that can be borne by the thin plate in the process of confrontation with the vibration reduction unit 212 is small, and it is easy to break. Therefore, the inclined rib plate 430 is provided to be connected to the first connecting plate 410 and the second connecting plate 420 respectively to form a triangular space 440, which improves the force bearing capacity of the first connecting plate 410 and can ensure that the connecting bracket 310 can transmit a large force without being easily damaged.
