Description

Technical Field

[0001] The utility model relates to the technical field of electronic tags, in particular to a hanging electronic tag. Background Art

[0002] In the field of Internet of Things identification, hanging electronic tags are widely used in scenarios such as warehouse management, retail price display, and industrial equipment identification.

[0003] Currently, LCD displays are commonly used for electronic tag displays. The continuous refresh of the LCD screen requires constant power supply, and the battery needs to be frequently replaced; content update depends on manual key input or data transmission through the USB interface, and it cannot respond to real-time dynamic information (such as promotional price changes, equipment status warnings). Especially in the warehouse logistics scenario, it is difficult to meet the identification requirements for rapid inbound and outbound.

[0004] Most of the existing installation structures of hanging electronic tags use bolt fixation or snap connection. The fixation methods mainly rely on single magnetic attraction or clamping. The magnetic attraction type is only applicable to metal surfaces, and the clamping type mostly uses fixed clamping arms, which are difficult to meet the multi-angle installation requirements of cylindrical components. Summary of the Utility Model

[0005] The technical problems to be solved by the utility model are the problems of inconvenient installation and disassembly, single fixation method, high power consumption of the display module, and inconvenient content update, and achieve the technical effects of flexible installation, efficient maintenance, and adaptive display.

[0006] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0007] A hanging electronic tag includes a tag body and a hanging bracket. The tag body is installed on the hanging bracket through a quick-release structure, and the tag body is equipped with an editing and display module; a pair of magnetic plates are provided on the back of the hanging bracket, and a placement groove is reserved between the magnetic plates. A clamping mechanism is provided in the placement groove. The clamping mechanism includes a mounting frame rotatably connected to the hanging bracket, and the clamping mechanism is flush with the back plate of the hanging bracket in the placement groove.

[0008] As an improvement, a modular slot is provided on the back of the tag body, the hanging bracket is provided with a one-way open slot that is slidably connected to the tag body, and a dovetail slider that is slidably matched with the modular slot is further provided.

[0009] As an improvement, the editing and display module includes an electronic ink display screen embedded in the front of the tag body, a microcontroller, and a power supply module. The electronic ink display screen is electrically connected to the microcontroller. The power supply module is a button battery or a wireless charging module. The tag body receives editing instructions from a terminal device through NFC or Bluetooth to achieve adaptive update of the display content.

[0010] As an improvement, the mounting bracket is rotatably connected to the suspension bracket through a damping rotating shaft. The end of the mounting bracket is connected with a pressing and clamping unit through an adapter ring. The adapter ring adopts a damping ring structure to realize the locking of the pressing and clamping unit at any angle.

[0011] As an improvement, the pressing and clamping unit includes a central fixing seat connected to the adapter ring. Symmetrically arranged jaws are hinged on both sides of the central fixing seat to form a lever structure. A pressing block is provided at one end of the jaw close to the central fixing seat, and a clamping plate is installed at the other end. A spring is connected between the pressing block and the central fixing seat.

[0012] As an improvement, the clamping plate is a bent structure adapted to cylindrical components, and toothed clamping blocks are installed between the opposite side surfaces.

[0013] As an improvement, a pair of storage holes are provided in the placement groove. The storage holes cooperate with the pressing block and the spring to make the end of the pressing block abut against the side wall of the placement groove.

[0025] The following further elaborates on the present utility model with reference to the accompanying drawings.

[0026] Please refer to the attached Figure 1 and the attached Figure 2 As shown, a hanging electronic label includes a label body 1 and a hanging bracket 2. A modular slot 8 is provided on the back of the label body 1, and the hanging bracket 2 is provided with a card slot 21 with a one-way opening. The card slot 21 is slidably connected to the label body 1, and a dovetail slider 22 slidably engaged with the modular slot 8 is also provided on the hanging bracket 2. During installation, the label body 1 is pushed along the direction of the card slot 21, and the dovetail slider 22 is inserted into the modular slot 8 to achieve quick fixation; during disassembly, the label body 1 is slid in the reverse direction to be removed, and the operation is convenient.

[0027] An editing and display module 3 is embedded on the front of the label body 1. As Figure 2 shown, the editing and display module 3 includes an electronic ink display screen 31, a microcontroller 32, and a power supply module 33. The electronic ink display screen 31 is electrically connected to the microcontroller 32, and the power supply module 33 can select a button battery or a wireless charging module according to requirements. The label body 1 communicates with terminal devices (such as mobile phones, tablets) through NFC or Bluetooth modules. After receiving an editing instruction, the microcontroller 32 controls the electronic ink display screen 31 to update the display content, such as commodity prices, inventory information, etc., without manual modification, improving efficiency.

[0028] It should be supplemented that the editing and display module 3 is integrated inside the label body 1 and adopts a hierarchical layout design. The microcontroller 32 is integrated in the center of the PCB board and is connected to the electronic ink display screen 31 through a wiring harness, supporting both NFC and Bluetooth 5.0 communication modes; the power supply module 33 provides two battery life solutions. The button battery solution is for two built-in batteries in parallel power supply, and the wireless charging solution is for integrating a wireless charging coil at the bottom of the PCB board, cooperating with an external charging base.

[0029] Editing and Display Module 3 Content Update Process: First, the terminal device (mobile phone / tablet) gets close to the label body 1 via NFC or connects through Bluetooth pairing; then, it sends format instructions (including parameters such as text, icons, font size, etc.) to the microcontroller 32; finally, after the microcontroller 32 parses the instructions, it drives the electronic ink display screen 31 to refresh and display the content.

[0030] Please refer to Appendix Figure 1 , Appendix Figure 3 , Appendix Figure 4 , Appendix Figure 5 and Appendix Figure 6 As shown in Appendix

[0031] On the back of the suspension bracket 2, there is a pair of magnetic plates 4. The magnetic plates 4 are made of strong magnetic materials and can be adsorbed on the surfaces such as metal shelves and equipment casings to achieve quick installation. A placement groove 5 is reserved between the magnetic plates 4 for accommodating the clamping mechanism 6 to ensure that the flatness error of the overall backplane is ≤0.2 mm in the non-clamping state; the clamping mechanism 6 includes a mounting frame 7 rotatably connected to the suspension bracket 2 through a damping rotating shaft 71. The end of the mounting frame 7 is connected to the pressing and clamping unit 73 through an adapter ring 72. The adapter ring 72 adopts a damping ring structure to adapt to the clamping requirements in different directions.

[0032] The pressing and clamping unit 73 includes a central fixing seat 731. On both sides of the central fixing seat 731, there are symmetrically hinged clamping jaws 732, forming a lever structure. At one end of the clamping jaw 732 close to the central fixing seat 731, there is a pressing block 733, and at the other end, there is a clamping plate 734 with a bent structure. Tooth-shaped clamping blocks 736 are installed on the opposite sides of the clamping plate 734. A spring 735 is connected between the pressing block 733 and the central fixing seat 731. A pair of receiving holes 51 are provided in the placement groove 5, and the receiving holes 51 cooperate with the pressing block 733 and the spring 735. When it is necessary to clamp cylindrical components (such as pipes and rods), press the pressing block 733, the spring 735 compresses, the clamping jaws 732 rotate and open around the hinge point, and after placing the component between the clamping plates 734, release the pressing block 733, and the spring 735 resets to drive the clamping jaws 732 to clamp the component. The tooth-shaped clamping blocks 736 increase the friction force to ensure firm clamping. In the non-use state, the end of the pressing block 733 abuts against the side wall of the placement groove 5, and the clamping mechanism 6 is received in the placement groove 5, flush with the backplane of the suspension bracket 2, keeping the whole body flat.

[0032] It should be noted that the magnetic adsorption fixing mode is applicable to magnetic surfaces such as metal shelves and distribution cabinets. It can be directly adsorbed for positioning and quickly complete the installation, which is suitable for the scenario of product labels with high-frequency changes; the spring 735 is selected as a stainless steel compression spring with a pre-compression amount of 3 mm to provide an initial clamping force; the surface of the clamping block 736 is processed with deep inclined tooth patterns to produce a good anti-slip effect when contacting the cylindrical surface.

[0033] When the present utility model is specifically implemented: the electronic tag can be installed by magnetic attraction or clamping according to actual needs. For example, in the supermarket shelf scenario, the tag is adsorbed on the metal shelf through the magnetic attraction plate 4 to facilitate the display of commodity information; in the industrial pipeline scenario, it is clamped on the pipeline by the clamping mechanism 6 to display the pipeline parameters in real time. The display content can be remotely updated through a terminal device, and the power supply module can regularly replace the button battery or continue to operate through wireless charging to ensure the long-term stable operation of the tag.

[0034] It is worth mentioning that the electronic ink display screen 31, the microcontroller 32, and the power supply module 33 in this new type are all existing devices well known to those skilled in the art, and their circuit connection methods and usage control methods are all prior arts.

[0035] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
