[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] This embodiment provides an electronic price tag, such as Figure 1-Figure 3 As shown, the electronic price tag includes a rear shell 1, an electronic ink screen 3 and a reinforcement plate 2.

[0044] The rear housing 1 defines a receiving groove 11, within which a reinforcement plate 2 is positioned. The electronic ink screen 3 is positioned on the side of the reinforcement plate 2 facing away from the rear housing 1. The reinforcement plate 2 provides support for the electronic ink screen 3, ensuring its structural strength during use and reducing the risk of breakage. In this embodiment, the electronic ink screen 3 is bonded to the side of the reinforcement plate 2 facing away from the rear housing 1 to enhance the connection strength between the electronic ink screen 3 and the reinforcement plate 2. This electronic ink screen 3 is conventional technology and will not be described in detail in this embodiment.

[0045] Furthermore, in this embodiment, the reinforcing plate 2 is an extruded plate-like structure, specifically a long, rectangular plate-like structure. Extrusion molding allows the reinforcing plate 2 to be molded in its width direction, unaffected by factors such as tooling and machining equipment. This results in good dimensional consistency across the width, facilitating subsequent assembly and enhancing overall structural strength. Furthermore, after the long, rectangular plate is formed using the extrusion process, only additional processing methods, such as cutting, are required to complete the production of the reinforcing plate 2. This significantly reduces processing time compared to CNC machining methods, resulting in lower manufacturing costs.

[0046] Optionally, the reinforcing plate 2 is detachably connected to the rear housing 1. The detachable connection facilitates assembly and disassembly, effectively reduces assembly time, improves manufacturing efficiency, and is also convenient for later maintenance and replacement.

[0047] Specifically, if Figure 3 and Figure 5 As shown, two first plug-in portions 12 are symmetrically arranged at the bottom of the accommodating groove 11 along its width. Two second plug-in portions 21 are correspondingly arranged on the side of the reinforcing plate 2 facing the bottom. When the reinforcing plate 2 is connected to the rear housing 1, the two first plug-in portions 12 can be inserted between the two second plug-in portions 21 and abut against the opposing side surfaces of the two second plug-in portions 21. In other words, each first plug-in portion 12 is connected to a corresponding second plug-in portion 21. The mating of the first plug-in portions 12 and the second plug-in portions 21 achieves a preliminary connection between the reinforcing plate 2 and the rear housing 1.

[0048] More specifically, refer to Figure 3 In this embodiment, two first plug-in portions 12 symmetrically arranged along the width of the accommodating groove 11 constitute a group. Multiple groups of first plug-in portions 12 are provided, and the multiple groups of first plug-in portions 12 are spaced apart along the length of the accommodating groove 11. Two second plug-in portions 21 extend along the length of the reinforcing plate 2, respectively. When the reinforcing plate 2 is connected to the rear shell 1, each group of first plug-in portions 12 can be inserted between the two second plug-in portions 21. Providing multiple groups of first plug-in portions 12, combined with the second plug-in portions 21 extending along the length of the reinforcing plate 2, helps improve the reliability of the connection between the reinforcing plate 2 and the rear shell 1. Of course, in other embodiments, multiple groups of second plug-in portions 21 are provided on the side of the reinforcing plate 2 facing the bottom of the groove, and the multiple groups of second plug-in portions 21 correspond one-to-one with the multiple groups of first plug-in portions 12. When the reinforcing plate 2 is connected to the rear shell 1, each group of first plug-in portions 12 can be inserted between the corresponding group of second plug-in portions 21. The one-to-one matching of the multiple groups of first plug-in portions 12 and the multiple groups of second plug-in portions 21 can also improve the reliability of the connection between the reinforcing plate 2 and the rear housing 1 .

[0049] At the same time, the above-mentioned design of arranging the first plug-in portion 12 and the second plug-in portion 21 along the length direction of the reinforcement plate 2 enables the reinforcement plate 2 to be directly pulled out from the rear shell 1 along its length direction when the reinforcement plate 2 is disassembled from the rear shell 1, and the mutual cooperation between the first plug-in portion 12 and the second plug-in portion 21 can also play a guiding role.

[0050] It is understandable that in other embodiments, only two first plug-in portions 12 may be provided, and the two first plug-in portions 12 extend along the length direction of the accommodating groove 11. Two or more groups of second plug-in portions 21 can also achieve a reliable connection between the reinforcing plate 2 and the rear housing 1.

[0051] More preferably, refer to Figure 5 and Figure 6 In this embodiment, a first guiding slope 121 is provided on the side of the two first plug-in connectors 12 facing away from each other. As the first guiding slope 121 moves away from the other first plug-in connector 12, it gradually approaches the bottom of the accommodating groove 11. The first guiding slope 121 facilitates smoother insertion of the first plug-in connector 12 and the second plug-in connector 21, improving assembly convenience.

[0052] Optionally, a snap-fit ​​structure is further provided between the reinforcing plate 2 and the rear shell 1 , and the snap-fit ​​structure is used to further connect the reinforcing plate 2 and the rear shell 1 .

[0053] Specifically, if Figure 3 、 Figure 5 and Figure 6 As shown, first latching protrusions 13 are provided on opposite widthwise walls of the receiving groove 11, and first latching grooves 22 are provided on corresponding widthwise end surfaces of the reinforcing plate 2. When the reinforcing plate 2 is connected to the rear housing 1, the two first latching protrusions 13 respectively engage within the two first latching grooves 22. The cooperation between the first latching grooves 22 and the first latching protrusions 13 achieves a more secure connection between the reinforcing plate 2 and the rear housing 1.

[0054] More specifically, refer to Figure 6 A second guiding slope 131 is provided on the side of the first latching protrusion 13 facing away from the bottom of the groove. As it moves away from the sidewall of the receiving groove 11, the second guiding slope 131 gradually approaches the bottom of the receiving groove 11. A third guiding slope 211 is provided on the sides of the two second plug-in portions 21 facing away from each other. As it moves toward the bottom of the receiving groove 11, the two third guiding slopes 211 gradually approach the center of the width of the reinforcing plate 2. When the reinforcing plate 2 is placed in the receiving groove 11 of the back cover 1, the cooperation between the third guiding slope 211 and the second guiding slope 131 enables the reinforcing plate 2 to be more smoothly engaged with the back cover 1, reducing labor consumption.

[0055] Alternatively, as Figures 1-4As shown, the electronic price tag further includes a fastener 4 , through which the reinforcing plate 2 and the rear shell 1 can be stably connected.

[0056] Specifically, the reinforcing plate 2 further defines a mounting hole 23, through which the fastener 4 passes and is screwed to the rear housing 1. In this embodiment, the fastener 4 can be a conventional fastener such as a screw or bolt in the prior art, which not only ensures a reliable connection between the reinforcing plate 2 and the rear housing 1 but also facilitates disassembly, facilitating the subsequent repair and replacement of components of the electronic price tag.

[0057] Alternatively, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the electronic price tag also includes an electronic control component. The electronic control component includes a circuit board 51 and an electrical connector. The circuit board 51 is arranged in the accommodating groove 11 and is located on the side of the reinforcement plate 2 away from the electronic ink screen 3. An avoidance groove 24 is provided on the reinforcement plate 2, and the electrical connector passes through the avoidance groove 24. The two ends of the electrical connector are electrically connected to the electronic ink screen 3 and the circuit board 51 respectively. The provision of the avoidance groove 24 can not only make the connection between the electronic ink screen 3 and the circuit board 51 more convenient, but also help to achieve the integrity of the electronic price tag structure. For example, the circuit board 51 can be selected as a PCB board, and the electrical connector can be selected as an FPC board. Their structures and principles are all existing technologies and will not be elaborated here.

[0058] Furthermore, the electronic price tag includes a battery 52, which is disposed within the rear housing 1 and electrically connected to the circuit board 51. For example, the battery 52 can be a lithium-manganese soft-pack battery, which not only takes up a small amount of space but also offers advantages such as good safety and high cost-effectiveness. The specific choice of battery 52 can be determined based on actual needs and is not limited in this embodiment.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
