Description

Technical Field

[0001] This utility model belongs to the field of electronic price tag technology, and specifically refers to an ultra-thin electronic price tag. Background Technology

[0002] Price tags are small labels affixed to goods to display price information and are an important tool for price labeling in the retail industry. They typically include information such as the product name, price, and barcode, allowing customers to understand the selling price and compare prices while shopping. Electronic price tags have replaced traditional paper price tags, primarily using electronic screens to display product information. This allows for remote adjustments to product information via a unified control system, facilitating rapid information updates, improving management efficiency, and reducing errors.

[0003] In existing technologies, electronic shelf labels are relatively thick, and stacking multiple electronic shelf labels will take up a lot of space, resulting in relatively high warehousing and transportation costs. Utility Model Content

[0004] The main purpose of this utility model is to provide an ultra-thin electronic price tag, which solves the problems existing in the prior art, facilitates stacking and storage, and reduces warehousing and transportation costs.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An ultra-thin electronic price tag includes a housing, a panel, a display screen, and a circuit board; the housing is provided with a first mounting groove matching the thickness of the display screen, and a second mounting groove recessed in the bottom wall of one end of the first mounting groove, the second mounting groove forming a step on the back of the housing; the display screen and the circuit board are respectively fitted into the first mounting groove and the second mounting groove and electrically connected; the panel covers the peripheral opening of the first mounting groove.

[0007] A limiting plate is provided in the second mounting slot. The bottom of the limiting plate is integrally connected to the bottom wall of the second mounting slot, and its top is flush with the bottom wall of the first mounting slot and abuts against the display screen to provide support.

[0008] Preferably, the bottom of the limiting plate is provided with a threading hole.

[0009] Preferably, the limiting plate is provided with a buckle for fixing the edge of the circuit board.

[0010] Preferably, the top of the limiting plate is recessed to form an arc surface corresponding to the position of the threading hole, and the buckle is disposed on the side wall of the limiting plate between the arc surface and the threading hole.

[0011] Preferably, a plurality of ribs are connected between the side of the limiting plate facing away from the circuit board and the side wall of the second mounting groove.

[0012] The ultra-thin electronic price tag also includes a connector; the connector is detachably mounted on the end face of the housing that is in the same direction as the second mounting slot and is electrically connected to the circuit board.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] The first mounting groove of this utility model matches the thickness of the display screen, which greatly reduces the thickness of the housing. A step is formed on the back of the housing to form a second mounting groove inside the housing, providing mounting space for the circuit board. When stacking several electronic price tags, their connectors can be removed and two electronic price tags can be stacked in opposite directions, thereby reducing the stacking height and reducing storage and transportation costs. In addition, due to the reduced housing thickness, the internal space is adapted to the volume of the display screen and circuit board, which can also reduce the material cost of the housing.

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] refer to Figure 1-3 As shown, this utility model discloses an ultra-thin electronic price tag, including a housing 1, a panel 2, a display screen 3, a circuit board 4, and a connector 5;

[0023] The housing 1 is provided with a first mounting groove 11 that matches the thickness of the display screen 3, and a second mounting groove 12 recessed in the bottom wall of one end of the first mounting groove 11. The second mounting groove 12 forms a step 13 on the back of the housing 1.

[0024] The display screen 3 and the circuit board 4 are respectively fitted into the first mounting slot 11 and the second mounting slot 12 and are electrically connected.

[0025] Panel 2 covers the peripheral opening of the first mounting groove 11;

[0026] The connector 5 is detachably mounted on the end face of the housing 1 that is in the same direction as the second mounting groove 12 and is electrically connected to the circuit board 4; the connector 5 is used to realize the electrical connection between the circuit board 4 and external electrical equipment.

[0027] Through the above solution, the thickness of the first mounting groove 11 of this utility model matches that of the display screen 3, thereby greatly reducing the thickness of the housing 1. A step 13 is formed on the back of the housing 1 to form a second mounting groove 12 inside the housing 1, providing mounting space for the circuit board 4. When stacking and storing several electronic price tags, the connector 5 can be removed and two electronic price tags can be stacked in a reversed manner (see...). Figure 4 This reduces the stacking height, thereby reducing warehousing and transportation costs. In addition, the reduced thickness of the housing 1 allows the internal space to be adapted to the volume of the display screen 3 and the circuit board 4, which also reduces the material cost of the housing 1.

[0028] The following are specific embodiments of the present invention.

[0029] A limiting plate 14 is provided in the second mounting groove 12. The bottom of the limiting plate 14 is integrally connected to the bottom wall of the second mounting groove 12, and its top is flush with the bottom wall of the first mounting groove 11, so as to support the display screen 3.

[0030] Furthermore, the circuit board 4 is disposed on the side of the limiting plate 14 facing the connector 5; a wire hole 15 is provided at the bottom of the limiting plate 14 so that the wire can pass through the limiting plate 14 to realize the electrical connection between the display screen 3 and the circuit board 4, and avoid the wire from interfering with the installation of the display screen 3; the other side of the limiting plate 14 forms a groove-shaped space for storing the wire.

[0031] Secondly, the aforementioned limiting plate 14 is provided with a buckle 16 for fixing the edge of the circuit board 4, thereby fixing the circuit board 4.

[0032] Furthermore, the top of the aforementioned limiting plate 14 is recessed at the position corresponding to the wire hole 15 to form an arc surface 17, and the buckle 16 is disposed on the side wall of the limiting plate 14 between the arc surface 17 and the wire hole 15. Through the cooperation between the arc surface 17 and the wire hole 15, the thickness of the limiting plate 14 at this position is reduced, making it elastic. Even if the buckle 16 is elastic, it can fix the circuit board 4 without external force, and it can also deform to allow the edge of the circuit board 4 to be disassembled and assembled quickly when subjected to external force.

[0033] In addition, a number of ribs 18 are connected between the side of the limiting plate 14 facing away from the circuit board 4 and the side wall of the second mounting groove 12 to reinforce part of the limiting plate 14.

[0034] The aforementioned panel 2 is made of glass, acrylic sheet, etc., used to limit the display screen 3 without obstructing its display content. It is relatively fixed to the housing 1 through snap-fit ​​connection, glue bonding, ultrasonic welding, etc.

[0035] The connector 5 is fixed to the housing 1 by means of a threaded connection, that is, by means of screw fastening or bolt and nut connection and fixation.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
