Description

Technical Field

[0001] This utility model belongs to the field of light-emitting device technology, and specifically relates to a shoe light assembly. Background Technology

[0002] With the increasing popularity of smart wearable products and children's footwear, shoe lights, as innovative products that combine decoration and functionality, are gaining more and more favor among consumers. Shoe lights are provided to shoe manufacturers as accessories before shoe production. The main control components of the shoe light, such as the control chip, sensors, and battery, are sealed within the housing; only the LED beads and switch (if any) are led out of the housing via wires. Because shoes are subjected to significant pressure and impact during use, the main control components of the shoe light are sealed using a fully enclosed injection sealant method. This involves pouring cured adhesive onto the outside of the main control components to form a hard protective shell.

[0003] However, in actual use, since shoe lights are supplied to shoe manufacturers before shoe production, due to factors such as storage time and product quality, a very small number of shoe lights may have batteries that have not reached the expected voltage level when installed on the shoes. This reduces the lifespan of the shoe lights. Because the batteries are encapsulated in the casing, current shoe lights cannot detect the battery voltage. This allows products with substandard battery power to enter the production line, affecting the product pass rate and causing unnecessary returns and damage to the brand image. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and the accompanying drawings. However, those skilled in the art will understand that this utility model is not limited to the accompanying drawings and the following embodiments.

[0024] As described herein, the term "including" and its variations can be understood as open-ended terms, meaning "including but not limited to". The terms "first", "second", etc., are used only to distinguish different features and have no substantive meaning. The terms "inner" and "outer" are used only to indicate the relative positional relationship between components.

[0025] This utility model embodiment proposes a shoe light assembly, such as Figure 1 As shown, it includes: a light-emitting diode 1, a chip motherboard 2, a battery 11, a low-voltage detection circuit 3, and a package housing 4. The chip motherboard 2, the battery 11, and the low-voltage detection circuit 3 are disposed inside the package housing 4, and the light-emitting diode 1 is disposed outside the package housing 4.

[0026] In one embodiment, the battery 11 provides electrical signals to the chip motherboard 2 and the light-emitting diode 1, the chip motherboard 2 provides control signals to the light-emitting diode 1, and the light-emitting diode 1 is connected to the chip motherboard 2 and the battery 11 via connecting wires led out from inside the package housing 4. In another embodiment, the battery 11 provides electrical signals to the chip motherboard 2, the chip motherboard 2 provides both electrical signals and control signals to the light-emitting diode 1, and the light-emitting diode 1 is connected to the chip motherboard 2 via connecting wires led out from inside the package housing 4.

[0027] The battery 11 is a disposable battery. Under the control of the control signal provided by the chip motherboard 2, the light-emitting diode 1 can exhibit a fixed or changing light-emitting state, thus enabling the shoe with the light-emitting diode 1 to also exhibit a fixed or changing light-emitting effect. The light-emitting diode 1 may include one or more LED beads, and the colors emitted by the multiple LED beads may be the same, partially the same, or completely different; the light-emitting diode 1 may also include one or more groups of LED beads, each group of LED beads including one or more LED beads, and the colors emitted by the multiple LED beads may be the same, partially the same, or completely different. Correspondingly, the colors emitted by the multiple groups of LED beads may be the same, partially the same, or completely different.

[0028] like Figure 2 As shown, the low-voltage detection circuit 3 includes: a voltage sampling circuit 12, a voltage comparator 13, and a low-voltage indication circuit 14. The voltage sampling circuit 12 is connected to the battery 11, the voltage comparator 13 is connected to the voltage sampling circuit 12, and the low-voltage indication circuit 14 is connected to the voltage comparator 13.

[0029] The voltage sampling circuit 12 samples the voltage of the battery 11 to obtain the sampled voltage of the battery 11; the voltage comparator 13 compares the sampled voltage with a preset reference voltage; and the low voltage indication circuit 14 indicates whether the battery 11 is in a low voltage state based on the comparison result of the voltage comparator 13.

[0030] In embodiments of this invention, the voltage detection function and the low-voltage indication function are combined in a shoe lamp product. The voltage sampling circuit, the voltage comparator, and the low-voltage indication circuit can be added to the mainboard (e.g., an MCU chip). Alternatively, the voltage sampling circuit, the voltage comparator, and the low-voltage indication circuit can be connected to the mainboard via connecting wires as independent circuit boards. By pre-setting a preset reference voltage value, the voltage comparator obtains a comparison result based on the preset reference voltage value and the voltage value sampled by the voltage sampling circuit. The low-voltage indication circuit can then indicate whether the battery is in a low-voltage state based on the comparison result of the voltage comparator. This invention adds voltage detection and comparison functions to existing shoe light products. It employs a linked design of a voltage sampling circuit and a voltage comparator to achieve intelligent detection of battery voltage status. Furthermore, it adds a low-voltage indication function using a low-voltage indication circuit, enabling voltage detection and status indication even when the battery is encapsulated within a casing. Additionally, the shoe light assembly provided by this invention, without altering the overall product packaging structure, allows the product to possess real-time battery voltage monitoring and intelligent indication functions upon leaving the factory through simple circuit design. This ensures battery voltage compliance and reduces the risk of defective products entering the production line.

[0031] In one embodiment, the voltage sampling circuit 12 includes a voltage divider resistor circuit (not shown), which is connected to the battery 11. The voltage divider resistor circuit reduces the voltage of the battery 11 and provides it to the voltage sampling circuit 12 for sampling. In one embodiment, the voltage divider resistor circuit may include an adjustable resistor, the resistance value of which can be adjusted according to the needs of the circuit. The voltage sampling circuit 12 collects the voltage at the adjustable terminal of the adjustable resistor as the sampling voltage of the battery 11. In another embodiment, the voltage divider resistor circuit may include multiple resistors connected in series. The voltage sampling circuit 12 collects the voltage across one or more of these resistors as the sampling voltage of the battery 11.

[0032] In one embodiment, the voltage comparator 13 can be a low-power, high-precision voltage comparator module, which can accurately detect the battery voltage after the shoe light assembly is packaged without interfering with the waterproof and dustproof performance of the product. In this way, the circuit design is simple, low-cost, and has high efficiency and reliable performance.

[0033] In one embodiment, the low-voltage indication circuit 14 is a low-level active circuit. When the comparison result of the voltage comparator 13 is low, the low-voltage indication circuit 14 is triggered to indicate that the battery is in a low-voltage state. When the voltage of the battery 11 is lower than the set value, the voltage comparator 13 automatically triggers the low-voltage indication circuit 14 to indicate that the battery 11 is in a low-voltage state. Conversely, if the voltage of the battery 11 is not lower than the set value, the voltage comparator 13 will not automatically trigger the low-voltage indication circuit 14, and the untriggered low-voltage indication circuit 14 indicates that the battery is in a normal state. Therefore, this embodiment of the invention can effectively distinguish whether the battery voltage meets the qualified standard, thus providing a direct detection of the battery voltage. In another embodiment, the low-voltage indication circuit 14 is a high-level active circuit. When the comparison result of the voltage comparator 13 is high, the low-voltage indication circuit 14 is triggered to indicate that the battery 11 is in a low-voltage state.

[0034] In one embodiment, the battery 11 is a button cell battery, and the preset reference voltage value can be the voltage threshold of the battery 11. The preset reference voltage value is equal to or greater than 85% of the rated voltage of the battery 11. For example, the rated voltage of the button cell battery is 3.4V, and the preset reference voltage value can be set to 3V for example.

[0035] In one embodiment, the low-voltage indication circuit 14 includes an alarm circuit (not shown). When the comparison result of the voltage comparator 13 is low, the alarm circuit is triggered to indicate that the battery 11 is in a low-voltage state; when the comparison result of the voltage comparator 13 is high, the alarm circuit is not triggered to indicate that the battery 11 is in a normal voltage state.

[0036] In one embodiment, the alarm circuit includes an indicator light, and the encapsulation housing 4 is a transparent housing. When the comparison result of the voltage comparator 13 is low, the indicator light illuminates and can be observed through the transparent encapsulation housing 4 to indicate that the battery 11 is in a low-voltage state; when the comparison result of the voltage comparator 13 is high, the indicator light does not illuminate to indicate that the battery 11 is in a normal voltage state. In another embodiment, the alarm circuit includes a buzzer. When the comparison result of the voltage comparator 13 is low, the buzzer sounds to indicate that the battery 11 is in a low-voltage state; when the comparison result of the voltage comparator 13 is high, the buzzer does not sound to indicate that the battery 11 is in a normal voltage state. It is understood that the alarm circuit may include an indicator light and a buzzer. The encapsulation housing 4 is a transparent housing. When the comparison result of the voltage comparator 13 is low, the indicator light illuminates and the buzzer sounds to indicate that the battery 11 is in a low-voltage state; when the comparison result of the voltage comparator 13 is high, the indicator light does not illuminate and the buzzer does not sound to indicate that the battery 11 is in a normal voltage state. When the alarm circuit includes an indicator light, the indicator light can not only be used as a traditional power indicator light, but also undertake the intelligent function of monitoring the health of the battery 11. In a preferred embodiment, the indicator light may be an LED indicator light 141, such as... Figure 3 As shown.

[0037] In one embodiment, such as Figure 4 As shown, the low-voltage detection circuit 3 also includes a switching circuit 15, which controls the on / off state of the low-voltage detection circuit 3. When the switching circuit 15 is normally open, the low-voltage detection circuit 3 is in an open state. When it is necessary to detect the low voltage of the battery 11, the switching circuit 15 is closed, making the low-voltage detection circuit 3 connected. Thus, the low-voltage indicator circuit 14 can be used to determine whether the battery 11 is in a low-voltage state. In this embodiment, the addition of the switching circuit enables real-time monitoring of the battery voltage through simple switching control. The low-voltage indicator circuit provides status indication of the battery voltage, avoiding traditional manual voltage measurement methods, improving detection efficiency and accuracy. Furthermore, the alarm circuit's warning status can quickly inform production line personnel whether the battery voltage meets the standard, greatly simplifying the production and testing process.

[0038] In one embodiment, the switching circuit 15 may include a mechanical switch or an electronic switch, and the electronic switch may be a touch switch or a wireless switch.

[0039] The shoe light assembly proposed in this embodiment solves the problem of difficult battery voltage detection, a common issue in the shoe light industry. It provides an automated and intelligent detection solution for production lines, avoiding product quality problems caused by substandard battery voltage. The technical solution proposed in this embodiment has broad application prospects, applicable not only to various shoe light products but also extending to other similar smart wearable products, toys, and electronic products.
