BRIEF DESCRIPTION OF DRAWINGS

[0014] The following drawings are only intended to schematically illustrate and explain the present disclosure, rather than limiting the scope thereof. In the drawings,

[0015] FIG. 1 illustrates a structural diagram of an electronic shelf label with an integrated light guiding structure according to the present disclosure in a exploded state.

[0016] FIG. 2 illustrates a schematic diagram of a mounting position of a front cover in an electronic shelf label with an integrated light guiding structure according to the present disclosure.

DETAILED DESCRIPTION OF EMBODIMENTS

[0017] For a clearer understanding of the technical features, objectives and effects of the present disclosure, specific embodiments of the present disclosure will now be described with reference to the drawings. Unless the indicated directions defined separately, any direction such as upward, downward, forward and backward mentioned herein are all based on those illustrated in FIG. 1 of the present disclosure, which are explained here together.

[0018] As illustrated in FIGS. 1 and 2, the present disclosure provides an electronic shelf label with an integrated light guiding structure, including a screen 6, a light guiding sleeve 7 and an indicator light 4. The light guiding sleeve 7 is light transmissive, and is disposed to sleeve the screen 6 along an edge thereof. A rear end face of the light guiding sleeve 7 is attached to the indicator light 4. A light guiding post 701 is formed at a position, which is on a front end face of the light guiding sleeve 7 and overlapped with the indicator light 4, i.e., the light guiding sleeve 7 is a columnar protrusion formed on the light guiding sleeve 7 and integrally formed therewith. By disposing the light guiding post 701, it is possible to guide light emitted from the indicator light 4. Since the light guiding post 701 is integrally formed with the light guiding sleeve 7, it is unnecessary to mount the light guiding post 701 separately, which reduces the number of internal structural portions of the electronic shelf label, thereby simplifying the internal structure and the circuit layout of the electronic shelf label, reducing the assembly difficulty of the whole product, effectively improving the production efficiency of the electronic shelf label and reducing the production cost. In addition, since being disposed to sleeve the screen 6, the light guiding sleeve 7 can achieve the dual-effects of light guidance and screen protection, thereby preventing corners of the screen from being damaged due to bumping, and prolonging the service life of the electronic shelf label.

[0019] In an alternative embodiment of the present disclosure, as illustrated in FIGS. 1 and 2, the electronic shelf label with an integrated light guiding structure further includes a rear shell 1, which is a plate-shaped structure disposed in a vertical direction. An accommodating groove 101 is formed on a front portion of the rear shell 1, and both the screen 6 and the indicator light 4 are located in the accommodating groove 101. The front portion of the rear shell 1 is provided with a front cover 2, which is fixedly connected to the front portion of the rear shell 1 and blocks an opening of the accommodating groove 101. The front cover 2 is a plate-shaped structure disposed in the vertical direction. By disposing the front cover 2, it ensures that the screen 6 and the indicator light 4 are firmly disposed in the accommodating groove 101. In addition, the front cover 2 is provided with a light-transmitting hole 202 at a position overlapped with the light guiding post 701, so that the light guiding post 701 can extend into the light-transmitting hole 202, for the convenience of light emergence.

[0020] Further, the light guiding sleeve 7 is made of a material that is transparent, partially-transparent (i.e., an area where the light guiding post 701 is located is transparent) or translucent, so as to ensure that the position on the light guiding sleeve 7 overlapped with the indicator light 4 is light transmissive. Exemplarily, the light guiding sleeve 7 is made of silica gel with light conductivity.

[0021] Further, an edge of the front cover 2 may be fixed with the rear shell 1 by, but not limited to, ultrasonic welding.

[0022] Further, as illustrated in FIGS. 1 and 2, a display window 201 is opened on the front cover 2 at a position overlapped with the screen 6, so that commodity information displayed on the screen 6 can be displayed to the outside through the display window 201.

[0023] In an alternative embodiment of the present disclosure, as illustrated in FIG. 1, the electronic shelf label with an integrated light guiding structure further includes a control panel 3 to which the indicator light 4 is connected, and a control signal output end of the control panel 3 is connected to a control end of the screen 6 through a flexible printed circuit (FPC), so that the commodity information displayed on the screen 6 can be controlled by the control panel 3.

[0024] Specifically, as illustrated in FIG. 1, the control panel 3 is interposed between the screen 6 and an inner wall of the accommodating groove 101, the control panel 3 is closely attached to a rear end face of the screen 6, and the control panel 3 is connected to the inner wall of the accommodating groove 101 by a screw 5, so as to ensure the stable connection of the control panel 3.

[0025] Further, as illustrated in FIG. 1, the inner wall of the accommodating groove 101 is provided with a plurality of positioning posts 102, the control panel 3 is provided with a plurality of positioning holes 301 matched with the positioning posts 102, and each of the positioning posts 102 is inserted into a corresponding positioning hole 301, so that the control panel 3 can be positioned in the accommodating groove 101 through the positioning posts 102 and the positioning holes 301, thereby further improving the stability of the control panel 3.

[0026] In an alternative embodiment of the present disclosure, as illustrated in FIGS. 1 and 2, a plurality of reinforcing ribs 103 are provided on the inner wall of the accommodating groove 101 and are disposed along an edge of the inner wall, and the plurality of reinforcing ribs 103 are abutted against an edge of the light guiding sleeve 7, so that the screen 6 and the light guiding sleeve 7 can be positioned in the accommodating groove 101 through the reinforcing ribs 103, and the stability of the screen 6 can be improved.

[0027] Those described above are only illustrative embodiments of the present disclosure, rather than limiting the scope thereof. Any equivalent change or modification made by persons skilled in the art without departing from the concept and principle of the present disclosure should fall within the protection scope of the present disclosure.
