Ultra-thin power failure emergency device

Abstract

This utility model proposes an ultra-thin power outage emergency device. The power outage emergency device includes a shell, inside which are arranged a power module, an inverter module, a control module, and a connection interface module. The shell is formed into a cubic spatial structure, with its interior configured as an installation space. The rear of the shell is a fixed surface. The control module is located in the upper part of the space inside the shell, the inverter module in the middle, and the power module in the lower part. The control module is electrically connected to the inverter module and the power module. The overall thickness of the shell is less than 100mm, and the edges of the shell are formed with fixing ears. The shell is the external protective structure of the power outage emergency device, and its dimensions are limited during design, mainly by limiting its thickness, because the power outage emergency device is mainly installed in the narrow space between the hoistway and the car. Controlling its thickness can meet the installation requirements and provide emergency power supply in the event of a power outage.

Description

Technical Field

[0001] This utility model relates to an improvement of an elevator emergency device, specifically an ultra-thin power outage emergency device. Background Technology

[0002] Machine-room-less elevators have a compact structure and limited space between the shaft and the car. In addition, there is a risk of power outages during elevator operation. Therefore, elevators need to have emergency power outage devices. These devices have emergency power supplies to ensure that the elevator can perform emergency operations inside the car when the external power supply fails. For example, the car can be stopped at the nearest floor and the doors can be opened. Traditional emergency power outage devices are large and cannot be adapted to the confined environment of machine-room-less elevators, thus limiting the realization of their functions and failing to effectively meet safety requirements. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide an ultra-thin power outage emergency device.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The power outage emergency device includes a housing, and a power module, an inverter module, a control module and a connection interface module are arranged inside the housing. The housing is formed into a cubic spatial structure, and its interior is set as an installation space. The rear of the housing is set as a fixing surface. The control module is set in the upper part of the space inside the housing, the inverter module is set in the middle part, and the power module is set in the lower part. The control module is electrically connected to the inverter module and the power module. The overall thickness of the housing is less than 100mm, and the edges of the housing are formed with fixing ears. The housing serves as the external protective structure for the power outage emergency device. Its dimensions are limited during the design phase, primarily in its thickness. This is because the emergency device is mainly installed in the confined space between the hoistway and the car. Controlling its thickness ensures that installation requirements are met. The overall rear portion is within 100mm, allowing for installation in various spaces. The housing houses the main working modules. The power module is the primary emergency power supply structure, used to store electrical energy for emergency power supply during power outages. The inverter module converts the stored DC power into AC power usable by the elevator. The control module monitors the status of the mains power and the power module, while also controlling the operation of the inverter module. The connection interface module is mainly used to connect wires for charging and discharging functions of the power module.

[0005] Furthermore, the housing is made of aluminum alloy, and a maintenance door is provided at the front of the housing. The maintenance door is connected to the housing in an openable and closable manner, and a display device is installed on the maintenance door. The display device is connected to the control module circuit and includes indicator lights and digital tubes. The aluminum alloy housing structure reduces overall weight, decreases workload during installation, and has a regular structure, allowing for installation on various surfaces such as the car top, car side, and hoistway facade. The maintenance door facilitates daily maintenance, ensuring long-term stable and effective function. The indicator lights and digital tubes display the working status, facilitating maintenance.

[0006] Furthermore, the power module includes a battery management circuit and a lithium-ion battery pack. The lithium-ion battery pack is fixed inside the housing. The battery management circuit is connected to the lithium-ion battery pack circuit, and also connected to the control module and the inverter module. The power module uses a lithium-ion battery pack, which has high energy density and is suitable for energy storage in a small volume. The function of the battery management circuit is to manage the charge and discharge state of the lithium-ion battery pack, ensuring that the lithium-ion battery pack is in a stable energy storage state and extending its working life.

[0007] Furthermore, the connection interface module is positioned adjacent to the control module. The connection interface module includes an AC power interface and a discharge interface. A wiring hole is provided on the housing corresponding to the connection interface module, through which wires enter the housing and connect to the connection interface module. This proximity of the connection interface module and control module saves PCB board installation space, facilitates wiring, and allows for easy configuration of heat dissipation structures, effectively reducing the size of the emergency device.

[0008] Furthermore, the housing is provided with heat dissipation holes distributed on the side surface of the housing, and the fixing ears on the housing are evenly distributed on the outer edge, with mounting holes formed on the fixing ears. The heat dissipation holes on the housing can effectively dissipate the heat during battery charging and discharging, avoiding power failure due to battery overheating and improving the reliability of emergency operation.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement of the emergency power outage device for elevators. Its size is effectively controlled, and it can be installed in a narrow elevator shaft environment. It is suitable for various installation environments of machine room-less elevators and improves the safety of elevators. Attached Figure Description
