Description

Technical Field

[0001] This invention belongs to the field of elevator technology, specifically relating to an elevator with an adjustable time delay knob. Background Technology

[0002] Elevators often require delayed door closing during operation. For example, in freight elevators, due to the large quantity of goods and the need for multiple entries and exits from the car for transport, coupled with the large size and difficulty of handling the goods, the time required for transport is longer, necessitating an extended door closing time. In residential elevators, elderly passengers, passengers carrying heavy objects, or passengers pushing strollers often require a longer door opening time to ensure safe entry and exit.

[0003] Currently, most elevators on the market are equipped with a fixed delay closing function. By configuring a delay button on the elevator control panel, users can enter the delayed closing mode by pressing the delay button. However, the delay time is preset by the manufacturer when the elevator leaves the factory. Users cannot flexibly adjust the delay time of the elevator door according to different usage scenarios and the needs of different people. If the delay time needs to be adjusted, professional personnel need to modify the elevator's system parameters. The fixed delay time often cannot meet the needs of diverse usage scenarios.

[0015] The beneficial effects of this invention are as follows: When a delayed closing of the elevator door is required, the user can rotate the car delay knob. The car delay knob sends a delay signal to the delay control circuit. The delay control circuit receives and processes the delay signal, sends the delay data to the car digital display module for display, and simultaneously sends it to the elevator controller. After the corresponding delay time, the elevator controller sends an electrical signal to the door closing relay, causing the door closing relay to close and energize, thereby sending a door closing signal to the elevator door operator. The elevator door operator then performs the door closing action, thus achieving delayed closing. The delay time can be freely adjusted by the car delay knob. The greater the rotation of the car delay knob, the longer the delay time. Furthermore, the delay time can be displayed on the car digital display module, allowing the user to intuitively see the elevator door closing time, making it suitable for different usage scenarios.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1 to 7As shown, this embodiment discloses an elevator with an adjustable delay knob, including a car, an elevator door operator 1, an elevator control panel 2, and an elevator controller 3. The elevator door operator 1 controls the opening and closing of the elevator doors. The elevator control panel 2 is installed inside the car. The elevator controller 3 is connected to the elevator door operator 1 via an opening relay 4 and a closing relay 5. The elevator controller 3 sends an opening signal to the elevator door operator 1 via the opening relay 4 to open the elevator door; the elevator controller 3 sends a closing signal to the elevator door operator 1 via the closing relay 5 to close the elevator door. The elevator control panel 2 is equipped with a car delay knob 6 and a car digital display module 7. The car delay knob 6 is used to rotate and adjust the elevator door delay time, and the car digital display module 7 is used to display the elevator door delay time. The car delay knob 6 is connected to the elevator controller 3 via a delay control circuit 8, and the car digital display module 7 is connected to the delay control circuit 8. When a delayed closing of the elevator door is required, the user can rotate the car delay knob 6. The car delay knob 6 sends a delay signal to the delay control circuit 8. The delay control circuit 8 receives and processes the delay signal, sends the delay data to the car digital display module 7 for display, and simultaneously sends it to the elevator controller 3. After the corresponding delay time, the elevator controller 3 sends an electrical signal to the door closing relay 5, causing the door closing relay 5 to close and energize, thereby sending a door closing signal to the elevator door operator 1. The elevator door operator 1 then performs the door closing action, thus achieving delayed closing. The delay time can be freely adjusted by rotating the car delay knob 6. The greater the rotation of the car delay knob 6, the longer the delay time. The delay time can be displayed on the car digital display module 7, allowing users to intuitively see the elevator's delayed closing time, which is suitable for different usage scenarios.

[0019] In this embodiment, the elevator is also equipped with a remote control 9, which is wirelessly connected to the elevator control panel 2. The remote control 9 includes a remote delay knob 10, a confirmation button 11, a remote digital display module 12, and a delay signal transmission module 13. The remote delay knob 10 and the confirmation button 11 are both connected to the delay signal transmission module 13. The remote delay knob 10 is used to remotely adjust the elevator door closing delay duration, and the confirmation button 11 is used to control the transmission action of the delay signal transmission module 13. The remote delay knob 10 is connected to the remote digital display module 12, which is used to display the elevator door closing delay duration adjusted by the remote delay knob 10. The elevator control panel 2 also includes a delay signal receiving module 14, which is connected to the delay control circuit 8. The delay signal transmission module 13 and the delay signal receiving module 14 are wirelessly connected, wherein the wireless communication can be WiFi, infrared, Bluetooth, or other wireless connection methods. When the user rotates the remote delay knob 10, the remote delay knob 10 sends a delay signal to the remote digital display module 12 and the delay signal transmitting module 13. The remote digital display module 12 displays the delay duration for the user to view and confirm. After confirming the delay duration, the user presses the confirmation button 11. The confirmation button 11 sends an electrical signal to the delay signal transmitting module 13. The delay signal transmitting module 13 then sends the delay signal from the remote delay knob 10 to the delay signal receiving module 14 via wireless communication. After receiving the delay signal, the delay signal receiving module 14 sends it to the delay control circuit 8. The delay control circuit 8 receives and processes the delay signal, sending the delay data to the car digital display module 7 for display, and simultaneously to the elevator controller 3. After the corresponding delay duration, the elevator controller 3 sends an electrical signal to the door closing relay 5, causing the door closing relay 5 to close and energize, thereby sending a door closing signal to the elevator door operator 1. The elevator door operator 1 then performs the door closing action, thus achieving delayed door closing. In addition, to facilitate user confirmation that the delayed signal sent by the remote controller 9 is received by the elevator control panel 2, the elevator control panel 2 also includes a delayed signal feedback module 15, and the remote controller 9 also includes a delayed feedback receiving module 16. The delayed signal feedback module 15 is connected to the delayed control circuit 8, and the delayed feedback receiving module 16 is connected to the remote control digital display module 12. The delayed signal feedback module 15 and the delayed feedback receiving module 16 are connected wirelessly. When the delayed signal receiving module 14 receives the delayed signal sent by the delayed signal transmitting module 13, it will send it to the delayed control circuit 8 for processing. After processing, the delayed control circuit 8 will send a feedback signal through the delayed signal feedback module 15. After receiving the feedback signal, the delayed feedback receiving module 16 sends it to the remote control digital display module 12 for display. The user can understand whether the delayed signal has been sent to the elevator control panel 2 to achieve delayed door closing control through the information displayed on the remote control digital display module 12.For example, the delay duration of the remote control digital display module 12 is displayed in red when the elevator control panel 2 does not receive the delay signal and does not receive a feedback signal; it is displayed in green when a feedback signal is received. This makes it easier for users to determine whether the delay signal has been sent to the elevator control panel 2, avoiding the problem that when users control the elevator door to close with a delayed time using the remote control 9, they cannot determine whether the delay signal has been sent to the elevator control panel 2 to execute the delayed door closing action.

[0020] In a preferred embodiment, the car delay knob 6 includes a car knob base 61. The outer side of the car knob base 61 is provided with a first knob device with an adjustment accuracy of "seconds" and a second knob device with an adjustment accuracy of "minutes". Inside the car knob base 61 are a first rotating device for driving the first knob device to rotate and reset according to the delay duration, and a second rotating device for driving the second knob device to rotate and reset according to the delay duration. The first and second rotating devices extend out of the car knob base 61 and are respectively connected to the first and second knob devices. When the user needs a shorter closing time, they can rotate the first knob device, which generates a delay duration in "seconds". The first rotating device drives the first knob device to reset after the delay duration. When the user needs a longer closing time, they can rotate the second knob device, which generates a delay duration in "minutes". The second rotating device drives the second knob device to reset after the delay duration. The first and second knob devices operate on the same principle. Specifically, the first knob device includes a first knob ring 62, a first pop-out conductive piece 63, a first fixed resistor ring 64, and a first toothed ring 65. The first fixed resistor ring 64 is fixed circumferentially along the outer side of the car knob base 61. The first fixed resistor ring 64 is provided with a first notch 641 for the first pop-out conductive piece 63 to pop out and cut off power. The first knob ring 62 is rotatably disposed on the outer side of the first fixed resistor ring 64. The first pop-out conductive piece 63 is elastically connected to the inner side of the first knob ring 62. The first toothed ring 65 is fixed to the inner side of the first knob ring 62. One end of the first pop-out conductive piece 63 and the first fixed resistor ring 64 are respectively connected to conductive wires. One of the conductive wires is connected to the power supply, and the other conductive wire is connected in series with the current sensor and then connected to the power supply. Thus, the first knob device forms a series circuit in which the power supply, the first pop-out conductive piece 63, the first fixed resistor ring 64 and the current sensor are connected in sequence. When the first knob ring 62 rotates, it drives the first pop-out conductive piece 63 to rotate to different positions to cooperate with the first fixed resistor ring 64. The current passes through the first fixed resistor ring 64 for different lengths, and the resistance of the first fixed resistor ring 64 will also change accordingly. Therefore, the current sensor will generate different current sensing signals in this circuit. The current sensing signals can be converted into corresponding delayed signals.The first rotating device includes a first motor 66 and a first gear 67. The first motor 66 is fixed inside the car knob base 61, and the first gear 67 is connected to the rotating shaft of the first motor 66. The side of the car knob base 61 is provided with a first through groove 611 for the first gear 67 to extend and mesh with the first gear ring 65. When the first motor 66 rotates, it drives the first gear ring 65 to rotate, and the first gear ring 65 drives the first knob device to rotate and reset. When the first ejector conductive piece 63 enters the first notch 641, the first ejector conductive piece 63 is de-energized from the first fixed resistor ring 64, and the current sensor has no current sensing signal. At this time, the control of the first motor 66 also stops working. Preferably, the end of the first ejector conductive piece 63 is provided with a guide slope 631. When the first ejector guide piece leaves the first notch 641, the guide slope 631 can guide the first ejector conductive piece 63 to be gradually compressed and smoothly leave the first notch 641.

[0021] Similarly, the second knob device includes a second knob ring 68, a second pop-out conductive piece 69, a second fixed resistor ring 70, and a second gear ring 71. The second fixed resistor ring 70 is fixed circumferentially along the outer side of the car knob base 61. The second fixed resistor ring 70 has a second notch for the second pop-out conductive piece 69 to pop out and cut off power. The second knob ring 68 is rotatably disposed on the outer side of the second fixed resistor ring 70. The second pop-out conductive piece 69 is elastically connected to the inner side of the second knob ring 68. The second gear ring 71 is fixed to the inner side of the second knob ring 68. One end of the second pop-out conductive piece 69 and the second fixed resistor ring 70 are respectively connected to conductive wires. One conductive wire is connected to a power source, and the other conductive wire is connected in series with a current sensor and then connected to a power source, thereby forming a series circuit in which the power source, the second pop-out conductive piece 69, the second fixed resistor ring 70, and the current sensor are connected in sequence. The second rotating device includes a second motor 72 and a second gear 73. The second motor 72 is fixed inside the car knob base 61, and the second gear 73 is connected to the rotating shaft of the second motor 72. The side of the car knob base 61 is provided with a second through groove 612 for the second gear 73 to extend out and mesh with the second gear ring 71. The working principle of the second knob device is the same as that of the second knob device, except that the unit of the current sensing signal is converted into a delay signal is different, which will not be described in detail here. The first through groove 611 and the second through groove 612 are offset along the axial direction of the car knob base 61 to avoid interference between the first rotating device and the second rotating device.

[0022] Similarly, the remote control delay knob 10 has a structure that is roughly the same as the car delay knob 6. The remote control delay knob 10 includes a remote control knob base 101. The outer side of the remote control knob base 101 is provided with a third knob device 102 with an adjustment accuracy of "seconds" and a fourth knob device 103 with an adjustment accuracy of "minutes". The inside of the remote control knob base 101 is provided with a third rotating device 104 for driving the third knob device 102 to rotate and reset according to the delay duration and a fourth rotating device 105 for driving the fourth knob device 103 to rotate and reset according to the delay duration. The third rotating device 104 and the fourth rotating device 105 extend out of the remote control knob base 101 and are respectively connected to the third knob device 102 and the fourth knob device 103. The confirmation button 11 is located in the middle of the remote control knob base 101. The front of the confirmation button 11 is a pressing surface, and the back of the confirmation button 11 has a raised first connecting post 111. The inner bottom surface of the remote control knob base 101 has a raised second connecting post 112. A compression spring 113 is sleeved on the outer side of the first connecting post 111. One end of the compression spring 113 is sleeved on the first connecting post 111, and the other end is sleeved on the second connecting post 112. The first connecting post 111 and the second connecting post 112 are arranged opposite each other along the central axis. A first conductive plate 114 and a second conductive plate 115 are respectively provided on the opposite end faces of the first connecting post 111 and the second connecting post 112. Both the first conductive plate 114 and the second conductive plate 115 are connected to conductive wires and are energized. In the normal state, the confirmation button 11 is in the pop-up position due to the elastic force of the compression spring 113, and the first conductive plate 114 and the second conductive plate 115 are separated. When the confirmation button 11 is pressed, the first conductive plate 114 and the second conductive plate 115 come into contact, and the first conductive plate 114 and the second conductive plate 115 are energized and transmit electrical signals to the outside.

[0023] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means is within the protection scope of the present invention.
