Description

Battery module and electronic price indicator including the same

An embodiment relates to a battery module and an electronic price indicator including the battery module.

Typically, in a retail store, paper labels are used to display product information such as sale price or discount information, unit price, and country of origin for products on shelves. In the price display method using the paper label, when the product information is changed or the product display position is changed, the paper label which is in use has to be discarded and a new paper label has to be created. Therefore, maintenance costs are incurred constantly. Waste paper is wasted, which has a negative impact on environmental protection.

Therefore, research and development of an electronic price indicator (or an electronic shelf label (ESL)) as a means for replacing a conventional paper label is actively carried out.

The electronic price indicator receives price related information of a corresponding commodity from a central control center (server) through a wireless device (for example, a gateway), displays the received price related information, and provides information on the commodity in real time It does.

At this time, the electronic price indicator displays the frequent information change or discount information for the corresponding product in real time, thereby providing the convenience of the user.

The electronic price indicator is connected to the power source for operation.

However, in the past, a separate battery was used to supply power to the electronic price indicator, but there was a problem in that the display of articles was limited due to size problems.

Also, there is a problem that the wire for connecting the battery and the electronic price indicator is exposed to the outside, which is not visually good, and the space for mounting the battery is insufficient when the hook-type shelf is mounted.

The electronic price indicator is connected to a PCU (Power Control Unit) for controlling power supplied through the battery.

However, since the conventional PCU does not have a separate fixing device, it can be easily moved to the left or right by an operator or a user, thereby being exposed to the danger of disconnection of a wire or the like.

In addition, since the distance between the battery and the PCU is long, it takes much time to wire the wire when connecting the wire, and problems such as wire chewing occur during the lathe operation.

Embodiments provide a battery module having improved waterproof capability and an electronic price indicator including the same, which can easily change battery capacity.

Also, an embodiment of the present invention provides an electronic price indicator, which is connected to an end of a shelf and connected to a power source, and is provided with a control unit capable of simultaneously supplying power and providing information.

The inserting portion 235 electrically connects the battery module 300 and the substrate 234 to supply electric power, and connection terminals 311 having various structures can be used. In an embodiment, the connection terminal 311 is provided with a connector structure and may have a removable structure.

The fixing groove 236 may be formed to a depth that does not penetrate the substrate 234. In an embodiment, the fixing portion 237 may be a screw, and may be screwed into the first housing 230 through the body 100 and a region of the housing where the battery module 300 is disposed.

Further, the fixing groove 236 may be disposed in an area adjacent to the inserting portion 235. When the control unit 200 is fixed to the body 100, external force is received by the connection terminal 311 connected to the battery module 300. The connection terminal 311 is inserted into the insertion portion 235 to apply electric power to the substrate 234, or exerts an external force on the substrate 234 when the connection terminal 311 is detached. The fixing groove 236 is disposed in a region adjacent to the inserting portion 235 to minimize an external force acting on the substrate 234 when the connecting terminal 311 is attached or detached.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.
