Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator technology, specifically to a flip-type elevator car top disinfection device. Background Technology
[0002] The implementation of ultraviolet (UV) sterilization technology in elevators currently faces two major challenges. Firstly, traditional fixed UV sterilization lamps are often directly installed on the car ceiling or embedded through pre-drilled openings. While convenient, this method limits the sterilization range, as the light can only penetrate through specific grid holes, leaving some areas inside the car ineffectively sterilized. Furthermore, the size of the openings requires a difficult trade-off between sterilization efficiency and aesthetics. Secondly, while suspended sterilization mechanisms attempt to expand the sterilization range through lifting mechanisms, their stability and safety are questionable due to the complex structural layout of the elevator car ceiling (such as beams and railings) and the variable-speed vibrations during operation. Additionally, they occupy valuable space when not in use, affecting the overall aesthetics and functional layout of the elevator.
[0003] Furthermore, both fixed and suspended ultraviolet (UV) sterilization devices face a common challenge: the concealed areas below the car ceiling and above the wall panels are difficult to disinfect effectively. These areas become sterilization blind spots due to the limitations of the lighting fixture installation location, increasing public health and safety risks. Therefore, developing an elevator UV sterilization solution that can comprehensively cover the sterilization area while also considering aesthetics, safety, and space utilization has become an urgent problem to be solved. Summary of the Invention
[0004] The purpose of this invention is to provide a flip-type elevator car top disinfection device to address the technical deficiencies mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0006] A flip-type elevator car top disinfection device includes a car top base plate, a disinfection window that runs through the car top base plate, and a flip-type disinfection mechanism that is rotatably mounted on the car top base plate. After flipping, the disinfection components mounted on the flip-type disinfection mechanism enter the car through the disinfection window to perform disinfection and sterilization.
[0007] Furthermore, the flipping disinfection mechanism includes a flipping plate, a disinfection component disposed on the flipping plate, and a drive component disposed on one side of the car roof base plate for driving the flipping plate to perform a flipping action.
[0008] Furthermore, the disinfection component includes a bracket arranged along the length direction on the top surface of the flip plate and an ultraviolet lamp fixed on the bracket. The bracket is fixed to the top surface of the flip plate by a snap ring. A first flange and a second flange are symmetrically and vertically arranged on both sides of the flip plate along the length direction. The first flange is driven to cooperate with the driving component through a first rotating shaft, and the second flange is rotatably cooperated with a bearing seat through a second rotating shaft. The bearing seat is fixedly arranged on the car top base plate.
[0009] Furthermore, the drive assembly includes a mounting plate fixedly disposed on one side of the top surface of the car roof base plate. A drive motor is fixedly disposed on the mounting plate by means of a first mounting plate flange. The output shaft of the drive motor is connected to one end of a flexible connecting shaft, and the other end of the flexible connecting shaft is connected to the first rotating shaft.
[0010] Furthermore, the mounting plate has a second mounting plate flange and a third mounting plate flange symmetrically arranged on the side of the mounting plate near the flip plate about the flexible connecting shaft. The second mounting plate flange and the third mounting plate flange are respectively installed with a positive detector and a negative detector. The outer side of the first flange of the flip plate is respectively provided with a sensing post that cooperates with the positive detector and the negative detector to determine whether the flip is in place.
[0011] Furthermore, a third flange is formed on one side of the flip plate along its length, and magnetic supports are provided on the side of the car top base plate near the second and third flanges, with magnetic blocks provided on the magnetic supports that magnetically engage with the second and third flanges.
[0012] Furthermore, a control board is also fixedly mounted on the mounting plate, and the control board is connected to the drive motor and the ultraviolet lamp.
[0013] Furthermore, a protective cover is provided on the mounting plate, which covers the drive motor and control board to form a protective layer.
[0014] Furthermore, before the flip-up plate flips, its bottom wall is flush with the car roof base plate; after the flip-up plate flips, the ultraviolet lamp extends completely into the car space.
[0015] Furthermore, the width of the disinfection window is greater than the width of the flip plate, allowing the flip plate to rotate freely within the disinfection window.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] This invention uses a drive assembly to rotate a tilting plate around a first and second pivot on both sides, allowing ultraviolet lamps mounted on the tilting plate to enter the elevator car through a disinfection window on the car top substrate for disinfection. This ingeniously designed and compact device enables comprehensive disinfection of the elevator car interior while avoiding potential impacts on occupants when disinfection is not being performed. Automated control and detection systems improve the reliability and safety of the device, while reducing operational complexity and labor costs. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] like Figure 1-9 As shown, a flip-type elevator car top disinfection device includes a car top base plate 1, a disinfection window 11 extending through the car top base plate 1, and a flip-type disinfection mechanism rotatably mounted on the car top base plate 1. After flipping, the disinfection components mounted on the flip-type disinfection mechanism enter the car through the disinfection window 11 to perform disinfection and sterilization. The flip-type disinfection mechanism includes a flip plate 2, disinfection components mounted on the flip plate 2, and a drive component mounted on one side of the car top base plate 1 for driving the flip plate 2 to perform the flipping action.
[0033] When not performing disinfection operations, the present invention features a flip-up disinfection mechanism in its initial position, meaning the flip-up plate 2 and its disinfection components are positioned above the car top base plate 1, and the disinfection components do not occupy or obstruct the space inside the elevator car. The disinfection window 11 serves as an opening penetrating the car top base plate 1. In the initial state, the flip-up plate 2 simultaneously forms a shield around the disinfection window 11, concealing components such as the ultraviolet disinfection lamp. This protects the ultraviolet disinfection lamp, emergency components, and other parts, while also protecting the occupants, preventing contact between occupants or objects and the ultraviolet disinfection lamp and other components, thus restoring the car's visually sealed, flat, and aesthetically pleasing appearance.
[0034] When a disinfection task is required, a signal is sent to the drive assembly via the control panel. Upon receiving the signal, the drive assembly begins operation, driving the tilting plate 2 to rotate around its axis. Under the action of the drive assembly, the tilting plate 2 gradually rotates from its initial position to its working position. During this process, the disinfection components on the tilting plate 2 move accordingly until they can enter the elevator car through the disinfection window 11. Once the tilting plate 2 and its disinfection components are fully inside the elevator car, the disinfection components begin operation. During the disinfection operation, the control system may monitor the process to ensure that the disinfection time meets preset standards. After the disinfection operation is completed, the control system sends a signal to the drive assembly again, driving the tilting plate 2 and its disinfection components back to their initial position. After the tilting plate 2 has fully reset, the disinfection window 11 is again covered by the tilting plate 2 to ensure the safety and cleanliness of the elevator operation.
[0035] Specifically, as shown in the figure, the disinfection component includes a bracket 21 arranged along the length of the top surface of the flip plate 2, and an ultraviolet lamp 22 fixed on the bracket 21. The bracket 21 is fixed to the top surface of the flip plate 2 by a snap ring 23. A first flange 24 and a second flange 25 are symmetrically and vertically arranged on both sides of the flip plate 2 along the length direction. The first flange 24 is driven to cooperate with the drive component through a first rotating shaft, and the second flange 25 is rotatably cooperated with a bearing seat 12 through a second rotating shaft. The bearing seat 12 is fixedly arranged on the car roof base plate 1. The drive component includes a mounting plate 3 fixedly arranged on one side of the top surface of the car roof base plate 1. A drive motor 4 is fixedly arranged on the mounting plate 3 through a first mounting plate flange 31. The output shaft of the drive motor 4 is connected to one end of a flexible connecting shaft 5, and the other end of the flexible connecting shaft 5 is connected to the first rotating shaft.
[0036] When not performing disinfection, the tilting plate 2 and its disinfection components (including the bracket 21 and the ultraviolet lamp 22) are located above the car top base plate 1 and are in a "retracted" state. When a disinfection task needs to be performed, the control board sends a signal to the drive motor 4. After receiving the signal, the drive motor 4 starts to run, and its output shaft transmits power to the first rotating shaft through the flexible connecting shaft 5. As the drive motor 4 rotates, the first rotating shaft drives the first flange 24 of the tilting plate 2 to rotate around its axis. At the same time, since the second flange 25 is rotatably engaged with the bearing seat 12 through the second rotating shaft, the tilting plate 2 can smoothly tilt around its center point. During the tilting process, the bracket 21 and its ultraviolet lamp 22 move accordingly until the ultraviolet lamp 22 can enter the elevator car through the disinfection window 11. The design of the flexible connecting shaft 5 allows the tilting plate 2 a certain degree of freedom during the tilting process while maintaining a stable connection with the drive motor 4. Once the tilting plate 2 and its ultraviolet lamp 22 are fully inside the elevator car or reach the predetermined disinfection position, the ultraviolet lamp 22 starts to work, emitting ultraviolet light for disinfection. The irradiation range and intensity of the ultraviolet lamp 22 are typically designed based on the size of the elevator car and disinfection requirements to ensure effective disinfection. After disinfection, the control board sends a signal to the drive motor 4, which reverses, causing the tilting plate 2 and its ultraviolet lamp 22 to return to their initial position. During the reset process, the ultraviolet lamp 22 needs to be switched off as necessary to avoid unnecessary irradiation of passengers or items inside the elevator. After the tilting plate 2 has fully reset, the disinfection window 11 is re-covered by the tilting plate 2 to ensure the safety and cleanliness of the elevator operation.
[0037] Specifically, as shown in the figure, the mounting plate 3 is symmetrically provided with a second mounting plate flange 32 and a third mounting plate flange on the side of the mounting plate 3 near the flip plate 2 about the flexible connecting shaft 5. The second mounting plate flange 32 and the third mounting plate flange are respectively installed with a positive detector 33 and a negative detector 34. The outer side of the first flange 24 of the flip plate 2 is respectively provided with a sensing post 26 that cooperates with the positive detector 33 and the negative detector 34 to determine whether the flip is in place.
[0038] When the tilting plate 2 begins to tilt, whether it tilts in the forward direction (near the forward detector 33) or the reverse direction (near the reverse detector 34), the sensing column 26 moves along with the tilting plate 2. If the tilting plate 2 tilts in the forward direction, when the sensing column 26 moves into the detection range of the forward detector 33, the forward detector 33 will send a signal indicating that the tilting plate 2 has tilted to the predetermined forward position. Similarly, if the tilting plate 2 tilts in the reverse direction, when the sensing column 26 moves into the detection range of the reverse detector 34, the reverse detector 34 will send a signal indicating that the tilting plate 2 has tilted to the predetermined reverse position. The signals from the detectors are received and processed by the control system. The control system can determine whether the tilting plate 2 has tilted to the correct position based on these signals, and accordingly control the drive motor 4 to stop or reverse, so as to achieve precise positioning and reset of the tilting plate 2. If the tilting plate 2 fails to tilt correctly (e.g., due to mechanical failure, drive motor failure, or external interference), the control system can issue a fault alarm or take other safety measures based on the detector signals to ensure the safe operation of the elevator.
[0039] Specifically, as shown in the figure, a third flange is formed on one side of the tilting plate along its length. Magnetic supports are provided on the side of the car roof base plate near the second and third flanges, and each magnetic support has a magnetic block that magnetically engages with the second and third flanges. When the tilting plate 2 is not in operation, its second flange 25 and third flange 27 will approach or contact the magnetic support 13. At this time, the magnetic block will use its magnetism to attract the second flange 25 and third flange 27, thereby firmly fixing the tilting plate 2 above the car roof base plate 1. The magnetic engagement not only provides additional fixing force but also enhances the stability of the tilting plate 2 in a static state. This helps prevent the tilting plate 2 from accidentally moving or shaking due to external factors (such as wind, vibration, etc.). After the disinfection operation is completed, when the control system sends a signal to reverse the drive motor 4, the tilting plate 2 will begin to reset under the action of the driving force. At this time, the magnetic attraction between the magnetic block and the second flange 25 and the third flange 27 will help the flip plate 2 return to the initial position smoothly, ensuring the accuracy and stability of the reset process.
[0040] Specifically, as shown in the figure, a control board 6 is also fixedly installed on the mounting plate 3, and the control board 6 is connected to the drive motor 4 and the ultraviolet lamp 22.
[0041] Specifically, as shown in the figure, a protective cover 7 is provided on the mounting plate 3, and the protective cover 7 covers the drive motor 4 and the control board 6 to form protection.
[0042] Specifically, such as Figure 8As shown, before the flip-up plate 2 flips, its bottom wall is flush with the car roof base plate 1. After the flip-up plate 2 flips, the ultraviolet lamp 22 extends completely into the car space. It is worth mentioning that before flipping, the flip-up plate 2 can block the disinfection window 11, making it more aesthetically pleasing. After flipping, the ultraviolet lamp completely enters the car space to disinfect the interior space of the car.
[0043] Specifically, as shown in the figure, the width of the disinfection window 11 is greater than the width of the flip plate 2, allowing the flip plate 2 to rotate freely within the disinfection window 11.
[0044] This invention uses a drive assembly to rotate a tilting plate around a first and second pivot on both sides, allowing ultraviolet lamps mounted on the tilting plate to enter the elevator car through a disinfection window on the car top substrate for disinfection. This ingeniously designed and compact device enables comprehensive disinfection of the elevator car interior while avoiding potential impacts on occupants when disinfection is not being performed. Automated control and detection systems improve the reliability and safety of the device, while reducing operational complexity and labor costs.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
