Description

Technical Field

[0001] The utility model relates to the technical field of power supply of elevator wireless light curtains, in particular to an uninterrupted wireless power supply device for elevator wireless light curtains. Background Art

[0002] The existing wireless power supply technology for elevator wireless light curtains (or wireless light curtains with safety touch panels) uses a similar wireless charging technology for mobile phones. When sending and receiving power, it can only be charged at a fixed arrival site to supplement the power supply of the wireless light curtain (such as lithium batteries or supercapacitors). The disadvantage is that the induction range of wireless charging transmission and reception is small, and it is impossible to charge and replenish power beyond the site range. Due to the unsustainable power supply, lithium batteries or supercapacitor components must be used for secondary power supply, which will cause the power supply device to be relatively large and cannot be installed in the elevator light curtain shell. If it is used, a shell must be added, which not only increases the cost but also makes it difficult to install; and in order to match the power supply, there are many accessories and complex circuits around the charging and discharging protection, charging and power supply lifting matching of lithium batteries, which leads to high costs. In addition, the key is point-to-point charging and replenishment of power, which has poor charging stability and is unsustainable. If the elevator power outage is long, the battery will be depleted and the charging time will be long; or the battery is damaged, causing the wireless light curtain to fail due to lack of power, making the elevator unable to use normally.
