Description

Technical Field

[0001] This utility model relates to the field of display pendants, and in particular to a display pendant with NFC function. Background Technology

[0002] Display hangers are electronic display devices with information transmission and reception capabilities, primarily used in supermarkets, convenience stores, pharmacies, and other similar establishments to display price information. Placed on shelves, they replace traditional paper price tags. Each electronic shelf tag connects to the store's computer database via wired or wireless network, displaying the latest product information on its screen. Electronic shelf tags effectively integrate the shelf into a computer program, eliminating the need for manual price tag changes and ensuring price consistency between the checkout counter and the shelf. The display hangers work with shelf-mounted components, allowing for convenient attachment and secure installation.

[0003] Current display mounts generally consist of a housing, a control module, and a display screen. The display screen is electrically connected to the control module, and both are housed within the housing. While this structure is simple and can basically fulfill the display function, the product's functionality is relatively limited and lacks competitiveness. Furthermore, the limited screen size prevents the display of much product information, causing inconvenience for users and failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current display mounts. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the existing technology, and its main purpose is to provide a display pendant with NFC function. This effectively solves the problems of existing display pendants having relatively simple functions and being not very competitive, and the fact that due to the limited size of the display screen, much of the product information cannot be displayed, causing inconvenience to users.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A display pendant with NFC functionality includes a housing, a control module, a shielding sleeve, a display screen, an NFC module, and a transparent protective sheet. The housing has a receiving cavity, a window, and an embedding slot. The window is located above and communicates with the receiving cavity. The embedding slot is located on the upper surface of the housing and communicates with the window. The length and width of the embedding slot are both greater than the length and width of the window. The control module is located in the receiving cavity. The shielding sleeve covers the control module and is located in the receiving cavity. The display screen is located in the receiving cavity and below the window. The display screen is located beside the control module and the shielding sleeve and is electrically connected to the control module. The NFC module is located in the receiving cavity and beside the control module and the display screen. The transparent protective sheet is embedded in the embedding slot and the window and is located above the display screen.

[0007] As a preferred embodiment, the housing includes a detachable upper housing and a lower housing, which together form the aforementioned receiving cavity. The aforementioned window is disposed on the upper housing, and the aforementioned mounting groove is disposed on the upper surface of the upper housing.

[0008] As a preferred embodiment, the bottom periphery of the upper housing is provided with an annular positioning groove, and the top periphery of the lower housing is provided with an annular positioning block. The annular positioning block is positioned in the annular positioning groove to effectively enhance the stability of the connection structure and facilitates quick and easy assembly.

[0009] As a preferred embodiment, the cross-section of the annular positioning groove is square, and correspondingly, the cross-section of the annular positioning block is also square, resulting in a simple structure and a firm and reliable connection.

[0010] As a preferred embodiment, the upper housing is provided with a positioning frame, which has a mounting cavity that communicates with the window and the receiving cavity. The display screen is placed in the mounting cavity, which helps to fix the display screen well, effectively enhances the stability of the connection structure, and is simple to operate and easy to assemble, bringing convenience to production.

[0011] As a preferred embodiment, the control module includes a PCB board and an FPC, which are disposed in an accommodating cavity. The aforementioned shielding sleeve covers the periphery of the PCB board. One end of the FPC is electrically connected to the PCB board, and the other end of the FPC is electrically connected to the display screen.

[0012] As a preferred embodiment, the NFC module is positioned between the control module and the display screen.

[0013] As a preferred option, the transparent protective sheet is a PVC transparent sheet. PVC material has good chemical stability and corrosion resistance, high hardness and strength, UV protection (anti-aging), fire resistance and flame retardancy (self-extinguishing), reliable insulation performance, smooth and flat surface, non-absorbent, non-deformable, easy to process, and other characteristics, which effectively improve product quality and extend product service life.

[0014] As a preferred embodiment, a silica coating is further provided, which is stacked on the upper surface of the transparent protective sheet and located in the embedding groove. Silica material has high hardness and good wear resistance, high temperature resistance and corrosion resistance, which effectively improves the product surface's ability to resist scratches and extends the product's service life.

[0015] As a preferred embodiment, the lower end of the housing is provided with a positioning hole for positioning in conjunction with external parts. Multiple guide blocks are provided on the inner wall of the positioning hole, and the extension direction of the multiple guide blocks is the same as the extension direction of the positioning hole. This effectively enhances the stability of the connection structure, can fix the product well, and is simple to operate and quick to assemble, bringing convenience to the user.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By placing the control module within the housing cavity, and the display screen within the housing cavity below the window (the display screen is positioned beside the control module and shielding sleeve and electrically connected to the control module), and placing the NFC module within the housing cavity beside the control module and display screen, this display pendant not only displays information but also has NFC functionality, making its features more diverse and competitive. By bringing an external NFC mobile terminal close to the product, information pre-stored in the NFC module can be read, providing users with more information to better understand the product, bringing convenience to users and meeting different needs. The shielding sleeve covering the control module prevents the metal layer in the control module from affecting the performance of the NFC module, improving product quality. With the embedding slot's length and width both greater than the window's length and width, and the transparent protective sheet embedded in the embedding slot and window above the display screen, the stability of the connection between the transparent protective sheet and the outer shell is effectively enhanced. The transparent protective sheet effectively protects the display screen from exposure, improving product quality, extending product lifespan, and meeting current needs.
