Description

Technical Field

[0001] This utility model relates to badges, and more particularly to an electroluminescent badge. Background Technology

[0002] Currently available luminous badges typically achieve illumination by incorporating different light-emitting elements within the badge itself. For example, patent CN2520110Y discloses a luminous badge that uses built-in light-emitting diodes (LEDs) encapsulated in epoxy resin. However, using LEDs significantly increases the overall thickness of the badge, compromising its structural dimensions and causing serious heat dissipation issues. Patent CN203986442U addresses the issue of opaque badges by extending the light-emitting element beyond the panel, but it still uses point light sources such as LEDs and fluorescent tubes, resulting in inconsistent illumination across the badge's pattern layer. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an electroluminescent badge. This electroluminescent badge has controllable thickness, excellent heat dissipation performance, and uniform and stable light emission across its entire surface, exhibiting rich surface light and shadow effects. The electroluminescent badge includes:

[0004] Base plate,

[0005] A cover plate for engaging with the base plate, wherein the cover plate and the base plate form a cavity structure.

[0006] The cavity structure includes a battery, a circuit board containing a drive module, and a switch located between the battery and the drive module on the circuit board.

[0007] An electroluminescent film disposed on the cover plate, and

[0008] Badge pattern layer on an electroluminescent film;

[0009] The battery and the driving module in the circuit board are electrically connected, and the driving module and the electroluminescent film in the circuit board are electrically connected. The driving module includes a driving chip, a boost circuit and a frequency conversion circuit.

[0010] This invention combines a thin electroluminescent film with a circuit board containing a drive module (which includes a driver chip, a boost circuit, and a frequency conversion circuit) that has boost and frequency conversion functions. This allows the electroluminescent film to emit light uniformly and stably without compromising the size and structure of the badge itself. As a result, the electroluminescent badge has controllable thickness and good heat dissipation performance, while also achieving uniform and stable light emission across the entire surface.

[0011] Preferably, the base plate has a cavity structure, and the cover plate is detachably connected to the base plate.

[0012] Preferably, when the cavity structure is on the base plate, the cover plate is a transparent cover plate or a semi-transparent cover plate, and the electroluminescent film is disposed on the inner surface of the cover plate.

[0013] Preferably, when the cavity structure is on the base plate, the cover plate is an opaque cover plate, and the electroluminescent film is disposed on the outer surface of the cover plate.

[0014] Preferably, the cover plate has a cavity structure, and the base plate is detachably connected to the cover plate.

[0015] Preferably, when the cavity structure is on the cover plate, the electroluminescent film is disposed on the outer surface of the cover plate.

[0016] The batteries used in this electroluminescent badge can be rechargeable batteries, disposable dry cell batteries, or disposable button batteries. The batteries include: lithium batteries with dimensions of 32mm × 20mm × 5mm (capacity approximately 250mAh); AAA dry cell batteries with a rated voltage of 1.5V, dimensions of 46mm × 32mm × 11mm (each battery capacity approximately 800mAh, generally requiring ≥3 cells); and button batteries with dimensions of 65mm × 25mm × 4mm (each battery capacity ≤200mAh, generally requiring ≥3 cells).

[0017] Preferably, the battery is a rechargeable battery, and the electroluminescent badge further includes a charging port located on the outer surface of the base plate or the side of the electroluminescent badge, wherein the rechargeable battery and the charging port are electrically connected; preferably, the length of the rechargeable battery is 28-35mm, the width is 18-25mm, and the thickness is ≤5mm; and / or, the charging port is a Type-C charging port. Using a rechargeable battery results in a large battery capacity, low cost, and a significant increase in the total electroluminescence time. The lithium battery is preferably a polymer lithium battery, which is reusable, small in size, has a large output current, and provides good driver brightness. Compared to rechargeable batteries, using AAA dry cell batteries results in a large size and thickness. If two dry cell batteries are used, the electroluminescent film will have low brightness or not emit light (because the driving voltage is too low, resulting in low brightness or causing the boost component to be too large, or even failing to achieve the light-emitting function), therefore at least three dry cell batteries are required. Button batteries, on the other hand, have low output current, low electroluminescent film brightness, and a short usage time.

[0018] Preferably, a charging indicator light is provided between the charging port and the rechargeable battery, which can be used to display the charging status of the badge.

[0019] Preferably, the circuit board containing the drive module also has a charging protection module; wherein the rechargeable battery and the charging protection module in the circuit board are electrically connected, and the charging protection module in the circuit board is electrically connected to the charging port. The inclusion of a charging protection module in this invention improves the safety of repeated charging of the badge. Furthermore, placing the charging protection module on the same circuit board as the drive module simplifies the internal structure of the badge and reduces additional wiring.

[0020] Preferably, a charging indicator light is provided between the charging port and the charging protection module in the circuit board and / or between the charging battery and the charging protection module in the circuit board, which can be used to display the charging status of the badge.

[0021] Preferably, the charging indicator light is located on the circuit board, which can simplify the internal structure of the badge and reduce additional wiring.

[0022] Preferably, the electroluminescent badge satisfies one or more of the following:

[0023] The inner surface of the cavity structure is divided into multiple regions by protrusions, which are used to fix the battery, the circuit board containing the drive module and / or the switch respectively.

[0030] The switch is mounted on the circuit board;

[0031] The total thickness of the electroluminescent badge is ≤15mm;

[0032] The electroluminescent badge also includes a transparent outer shell that is detachably connected to the cover plate.

[0033] This invention divides the inner surface of the cavity structure into multiple areas by protrusions, thereby fixing and separating the components. This prevents damage to the badge caused by the movement of internal components such as circuit boards and batteries during use.

[0034] Preferably, the area for fixing the battery is formed by fixed protrusions and / or movable protrusions. The fixed protrusion can be a single protrusion formed integrally or multiple protrusions spaced apart.

[0035] In this invention, a fixing component is provided on the outer surface of the base plate for fixing and wearing the badge.

[0036] Preferably, the electroluminescent film and the driving module in the circuit board are electrically connected via a first lead; wherein one end of the first lead is adhered to a predetermined area (e.g., the central area) of the electroluminescent film, and / or the other end of the first lead is electrically connected to the driving module of the circuit board via a connector. Adhering one end of the lead to the central area of ​​the light-emitting film offers the advantage of being thin and conforming well.

[0037] Preferably, when the electroluminescent film is disposed on the outer surface of the cover plate, the electroluminescent film and the driving module in the circuit board are electrically connected via a first lead; wherein one end of the first lead is adhered to a predetermined area (e.g., the central area) of the electroluminescent film, and / or the other end of the first lead is electrically connected to the driving module of the circuit board via a connector, and the cover plate is provided with a first through hole, through which the first lead passes to achieve the electrical connection between the electroluminescent film and the driving module in the circuit board.
