Description

Power rail for electronic shelf labels

[0001] The present invention relates to a power rail for electronic shelf labels.

[0002] The Electronic Shelf Label (ESL) system is designed to enhance the efficiency of product purchasing and store operations by linking ESL tags with POS (point-of-sale) devices to display various information in real time, such as product price, price per unit, sale details, and stock quantity. The power supply method for such ESL systems is one of the critical challenges.

[0003] Typically, ESLs use batteries as a power source, but this poses a problem that reduces operational efficiency by incurring additional manpower and costs associated with periodic battery replacement. Furthermore, large quantities of discarded batteries act as a burden that causes environmental pollution. To address these drawbacks, the need for power rails capable of continuously supplying power to ESLs has emerged, and recently, there has been a demand for the development of power rails utilizing solar energy.

[0004] However, conventional power rail technology has the following structural, aesthetic, and safety limitations.

[0005] The commonly used 'T'-shaped rail lacks durability, and the open rear structure exposes internal equipment, compromising safety and making it difficult to attach to flat surfaces using double-sided tape.

[0006] In addition, if a controller or battery is housed inside the power rail, the appearance is not neat. The placement of the electrodes is a particular issue; placing the electrodes on the front spoils the aesthetics and is unsafe due to the exposure, while placing them on the rear requires a through hole for connection with the ESL tag, which detracts from the design.

[0007] In addition, if a straight electrode structure is adopted, there is a disadvantage that the overall size of the rail increases when multiple electrodes are configured.

[0008] These chronic problems with conventional power rails also pose a significant obstacle to integrating solar cells. Attaching solar cells to the exterior of the existing rail severely detracts from the aesthetics, while embedding them internally risks further worsening the durability of an already fragile structure.

[0009] Therefore, there is an urgent need to develop a solar power rail with a new structure that can resolve the inconvenience of battery replacement and environmental issues, while overcoming the durability, safety, and design limitations of existing power rails.

[0010] The main objective of the present invention is to provide a compact solar power rail for electronic shelf labels that can operate without battery replacement and has improved durability and energy efficiency.

[0011] In addition, the present invention provides a power rail for electronic shelf labels with a multi-electrode structure for power supply and data communication.

The protective portion (162) may be formed extending from the end of the second extension portion (160) with a predetermined slope. When the rail main body portion (100) and the shelf fastening portion (91) are fastened together, the protective portion (162) covers the fastening point on the lower part of them to provide a finishing finish. Additionally, due to the protective film structure of the protective portion (162), the product on the shelf is not caught, and the power rail (10) can be firmly fastened to the shelf while covering the fastening structure between the rail main body portion (100) and the shelf fastening portion (91).
