Description
Technical Field
[0001] The present application relates to the technical field of elevators, and in particular to an elevator emergency panel. Background Art
[0002] Vertical elevators are essential hardware components for building and home furnishings. They are frequently used for daily commuting and home use, and their cabins are highly utilized. Sudden power outages caused by mains power line failures are common. If the elevator cabin is not equipped with an emergency circuit board, the rapid descent of the cabin at a high level after this event can cause serious casualties to those inside, as well as damage to the cabin and other elevator equipment due to abnormal descents and stops, resulting in economic losses. To avoid losses caused by abnormal elevator operation, most elevator systems use an emergency inverter device, independent of the elevator's mains power supply system, to power the elevator control system. The emergency inverter device outputs an emergency signal, and the elevator cabin control system receives the emergency signal and controls the elevator cabin to slowly run to the level floor. The emergency signal is generated by the inverter system within the emergency inverter device.
[0003] Vertical elevators are equipped with emergency devices to improve safety. Emergency inverters cannot solve other sudden elevator failures caused by abnormalities in the elevator control system or emergency system. Therefore, vertical elevators are usually equipped with independent brake release devices that can be operated outside the elevator shaft to release the brake and move the elevator to solve emergency operations caused by electrical failures or power failures.
[0004] In existing technologies, elevator emergency inverters and brake release devices require two separate transformers for inverter-boost conversion. This requires additional supporting conversion circuitry, increasing costs, occupying a large volume, and complicating control, reducing product safety. When an elevator enters an emergency or braking state, existing elevator systems require the purchase of additional functional modules, such as fan cooling drive modules and announcement modules, based on the specifications of the elevator manufacturer and the emergency device. These commercially available modules have fixed parameters, resulting in poor adaptability and inflexible use. Furthermore, their single output power supply voltage cannot accommodate elevators with varying voltage requirements. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.
[0027] As used herein, the term "include" and its variations represent open inclusion, ie, "including but not limited to." Unless otherwise stated, the term "or" means "and / or."
[0028] like Figure 1 The following is a functional block diagram of the elevator emergency panel of the utility model: Figure 2 FIG. 1 shows a circuit diagram of a fan heat dissipation drive module in an embodiment of an elevator of the present invention; FIG. Figure 3 FIG. 1 shows a circuit diagram of a buzzer module in an embodiment of the present invention. Figure 1 As shown, the present invention provides an elevator emergency panel, which has a control module and a functional module. The functional module includes a mains power acquisition module, a charging energy storage module, an isolation boost module, a mains power and inverter switching module, a release and inverter switching module, and a communication module; the functional module is connected to the control module and performs function conversion based on the control module; the communication module connects the control module and the elevator main control device; the mains power and inverter switching module are electrically connected to the mains power acquisition module and the charging energy storage module respectively, and the control module is electrically connected to the release and inverter switching module and the isolation boost module respectively, and the release and inverter switching module is connected to the release output module. The control module controls the charging energy storage module to start charging according to the mains access situation, and drives the release and inverter switching module to switch the output signal type according to the mains access situation. The output signal type includes an inverter conversion signal and a brake conversion signal.
[0029] After the brake release and inverter switching module outputs an inverter conversion signal to the brake release output module, the brake release output module outputs a signal that drives the elevator car into an emergency state, causing the elevator car to slowly travel to the floor. The elevator emergency panel of this utility model is equipped with a control module and a functional module. The functional module is composed of a basic circuit composed of commonly used electronic components. This utility model can be adapted to different elevator manufacturers and emergency devices by compiling the control module's single-chip microcomputer program or adjusting the parameters of the functional module. Elevator control systems of different elevator manufacturers have different performance parameters, and different emergency devices, such as buzzer power, also vary. When the parameters of elevator manufacturers and emergency devices change, the control logic can be adjusted by compiling the single-chip microcomputer program in the emergency panel control module, or by adjusting the parameters of the basic circuit components of the functional module to achieve adaptability. The inverter conversion signal is also the emergency signal that drives the elevator into an emergency state. The duration of the elevator entering the emergency state after a mains power outage can be set by compiling the single-chip microcomputer program in the emergency panel control module, such as to 5 seconds or 15 seconds. By compiling different single-chip microcomputer programs in the emergency panel control module, the operating states of the brake release and inverter switching modules can be flexibly changed.
[0030] The elevator emergency panel features two mains detection circuits: the first located on the mains acquisition module, and the second located on the charging and energy storage module. These circuits detect secondary mains signals, identifying the presence of mains power, and enhancing the panel's responsiveness.
[0031] The functional module of the elevator emergency panel also includes a release switch. When the release switch is pressed manually, the inverter and switching module outputs a brake conversion signal.
[0032] The release and inverter switching module of the elevator emergency panel includes a transformer with at least a first output pin and a second output pin. When the release and inverter switching module outputs an inverter conversion signal, the transformer output pin is the first output pin; when the release and inverter switching module outputs a brake conversion signal, the transformer output pin is the second output pin. By converting the output signals of the release and inverter modules, the elevator emergency panel incorporates both release and inverter output functional modules. The release module and the inverter output module share a transformer with at least one output pin. By converting the output pin, the conversion between the release function and the inverter output signal is achieved. Furthermore, by compiling the program of the single-chip microcomputer in the elevator emergency panel control module, the inverter output voltage of the elevator emergency panel can be adjusted from 220V to 380V. Through basic hardware functions and single-chip microcomputer adjustments, the output voltage or current of the elevator emergency panel can be flexibly modulated.
[0033] The elevator emergency panel's transformer is equipped with a third output pin, which serves as a backup output voltage pin. This pin uses the transformer's neutral point as a voltage output port, also serving as a backup output voltage pin. Using the transformer's three busbars, it inverts three voltages, such as 0V, 270V, and 540V. These voltages can be modulated to different output voltage amplitudes using the microcontroller program compiled in the control module. The number of backup voltage pins can be one or more, with pin configuration tailored to actual needs. By adding backup output voltage pins for the transformer in the brake release and inverter output modules, users can select different backup output voltage pins based on the elevator's operating voltage, making the elevator emergency panel compatible with two or more elevators with different operating voltages.
[0034] The functional modules of the elevator emergency panel also include a display module, which is connected to the control module. The display panel is located on the side of the elevator car and is used to display the current operating status of the elevator to occupants in the elevator car when there is no mains power. The communication module synchronously displays the operating status of the elevator and the number of occupants on the exterior wall display panel of the elevator car. The exterior wall elevator display panel indicates whether there are trapped people in the elevator, whether the elevator is under maintenance or in an emergency state with trapped people awaiting rescue. The display status of the display can be manually switched from within the elevator car through the elevator emergency panel of the utility model.
[0035] The functional module of the elevator emergency panel also includes a buzzer module, which is connected to the control module and is used to drive the buzzer on the outer wall of the elevator car to sound when there is no mains power access and the elevator enters an abnormal state. Figure 3 The circuit diagram of the buzzer module in one embodiment of the elevator of the present invention is shown. The functional module of the elevator emergency panel also includes a fan heat dissipation drive module, which is connected to the control module and is used to drive the heat dissipation device in the elevator car when there is no mains power. Figure 2 The figure shows a circuit diagram of a heat dissipation drive module in an embodiment of the elevator of the present invention.
[0036] The elevator emergency panel of the present invention can be used when the elevator cannot safely stop at the leveling floor due to various faults. When the elevator is under maintenance, all functions of the elevator are normal. Maintenance personnel need to use the elevator release function during maintenance and inspection. The release function of the elevator emergency panel can be manually operated through the release switch to enable the elevator to slowly move to the leveling floor, ensuring the elevator's safe and smooth emergency braking. The inverter function is automatically switched when it detects that there is no mains power access, ensuring that the elevator automatically moves slowly to the leveling floor when there is no mains power access. The elevator emergency panel of the present invention has a two-in-one release function and inverter function.

Those skilled in the art will understand the specific meanings of the terms in this utility model based on specific circumstances.
[0038] The above embodiments are merely specific embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the present invention. It should be noted that those skilled in the art will readily be able to make various modifications and improvements without departing from the scope of the present invention, and such obvious substitutions are all within the scope of protection of the present invention.
