Description

Technical Field

[0001] This utility model relates to the field of earphone charging cases, specifically to a TWS earphone charging case with temperature and humidity detection function. Background Technology

[0002] In today's electronic device market, TWS earbuds (true wireless earbuds, often referring to Bluetooth earbuds) are highly favored by consumers for their convenience and excellent sound quality. As an important accessory for TWS earbuds, the charging case is also receiving increasing attention for its richer and more comprehensive functionality. From the perspective of overall industry development trends, charging cases are no longer limited to simply providing charging and storage functions for earbuds; expanding into more practical functions has become a key direction for enhancing product competitiveness.

[0003] Currently, there are many Bluetooth earphone charging cases on the market that can detect temperature, humidity, or temperature and humidity. For example, a Bluetooth earphone charging case disclosed in patent publication number CN111193982A and an earphone charging case with temperature, humidity, clock, and day of the week disclosed in patent publication number CN220401932U. Although existing products have the function of detecting temperature, humidity, or temperature and humidity, the detected data cannot be easily obtained and used by users. There is a lack of effective data transmission mechanism. Often, the temperature and humidity data can only be displayed locally in the charging case and cannot interact with external devices.

[0004] The above problems are worth solving. Utility Model Content

[0005] To address the issues of circuit board deformation and low assembly efficiency of integrated components caused by uneven distribution of multiple power devices in high-power modules, this invention provides a TWS earphone charging case with temperature and humidity detection function.

[0006] The technical solution of this utility model is as follows:

[0007] A TWS earphone charging case with temperature and humidity detection function includes a charging case body, a main control circuit board built into the charging case body, and a temperature and humidity sensing module. The temperature and humidity sensing module is electrically connected to the main control circuit board through a flexible circuit board. The temperature and humidity sensing module is used to collect ambient temperature and humidity data and transmit it to the MCU on the main control circuit board through the flexible circuit board.

[0008] The main control circuit board is equipped with a charging connection terminal. The TWS earphones are electrically connected to the main control circuit board through the charging connection terminal to obtain the temperature and humidity data processed by the MCU and temporarily store it in the storage module of the TWS earphones. After the TWS earphones establish a Bluetooth communication connection with the mobile phone, they transmit the temporarily stored temperature and humidity data to the mobile APP through the Bluetooth protocol.

[0009] As a preferred embodiment of this utility model, a rechargeable battery is built into the bottom of the charging case body. The rechargeable battery is electrically connected to the main control circuit board. The TWS earphones are electrically connected to the main control circuit board through the charging connection terminal to obtain electrical energy from the rechargeable battery.

[0010] As a preferred technical solution of this utility model, the top side of the charging case body is provided with an independent partition compartment, and the partition compartment houses the temperature and humidity sensing module.

[0011] Furthermore, the charging compartment body is provided with a ventilation window corresponding to the position of the partition compartment to ensure that the temperature and humidity sensing module is connected to the external environment.

[0012] Furthermore, the ventilation window is equipped with a perforated dustproof membrane.

[0013] As a preferred technical solution of this utility model, the charging case body includes a top compartment and a bottom compartment. The top compartment is provided with a receiving slot for placing TWS earphones, and the bottom compartment is provided with a battery compartment for installing rechargeable batteries. The main control circuit board is fixedly installed between the top compartment and the bottom compartment, and one end of the charging connection terminal is electrically connected to the main control circuit board, while the other end passes through the receiving slot of the top compartment.

[0014] As a preferred technical solution of this utility model, the top of the charging case body is connected to a cover that can be opened and closed. An opening detection component is provided between the cover and the charging case body. The opening detection component is connected to the main control circuit board and is used to detect the opening and closing state of the cover. When the cover is opened, the main control circuit board triggers the TWS earphones to establish a Bluetooth communication connection with the mobile phone.

[0015] The advantages of this utility model based on the above solution are as follows:

[0016] This invention integrates a temperature and humidity sensing module into the charging case of TWS earphones, and combines the electrical connection design between the flexible circuit board and the main control circuit board to realize the real-time acquisition and transmission of environmental temperature and humidity data. The data collected by the temperature and humidity sensing module is processed by the MCU of the main control circuit board and then transmitted synchronously to the storage module of the TWS earphones through the charging connection terminal for temporary storage, so that the earphones can still wirelessly transmit data to the mobile APP via Bluetooth communication protocol after being removed from the charging case.

[0017] This invention breaks through the limitations of existing technologies where temperature and humidity data can only be displayed locally in the charging case and cannot interact with external devices. It constructs a complete data link of "charging case detection - earphone storage - mobile phone display", enabling users to conveniently obtain real-time temperature and humidity information through their mobile phones.

The term "a plurality of" means two or more, unless otherwise expressly and specifically defined.

[0025] like Figure 1 and Figure 2 As shown, a TWS earphone charging case with temperature and humidity detection function includes a charging case body 1, a main control circuit board 4 built into the charging case body 1, and a temperature and humidity sensing module 2. The temperature and humidity sensing module 2 is electrically connected to the main control circuit board 4 through a flexible circuit board 3. The temperature and humidity sensing module 2 is used to collect ambient temperature and humidity data and transmit it to the MCU (microcontroller) on the main control circuit board 4 through the flexible circuit board 3.

[0026] The main control circuit board 4 is equipped with a charging connection terminal 5. The TWS earphones 6 are electrically connected to the main control circuit board 4 through the charging connection terminal 5 to obtain the temperature and humidity data processed by the MCU and temporarily store it in the storage module of the TWS earphones 6. After the TWS earphones 6 establish a Bluetooth communication connection with the mobile phone, they transmit the temporarily stored temperature and humidity data to the mobile APP via the Bluetooth protocol. The charging connection terminal is a pogo pin probe (i.e., a spring pin) used to realize the electrical connection between the main control circuit board and the TWS earphones and data transmission.

[0027] In the charging case of the TWS earbuds 6 with temperature and humidity detection, the temperature and humidity sensing module 2 collects real-time temperature and humidity data from the environment and transmits the data to the MCU on the main control circuit board 4 via the flexible circuit board 3. The MCU processes the data and stores it in the main control circuit board 4. When the TWS earbuds 6 are placed in the charging case, they are electrically connected to the main control circuit board 4 via the charging connection terminal 5. They can not only draw power from the rechargeable battery 7 for charging, but also receive the temperature and humidity data processed by the MCU and temporarily store it in their own storage module. When the user opens the charging case lid 14, the TWS earbuds 6 activate the Bluetooth function and establish a Bluetooth communication connection with the mobile phone. At this time, the TWS earbuds transmit the temporarily stored temperature and humidity data in the storage module to the mobile APP via the Bluetooth protocol.

[0028] The real-time ambient temperature and humidity data collected by the temperature and humidity sensing module is typically transmitted in digital signal form, with each data collection consisting of 2-4 bytes. The TWS earbuds are equipped with a storage module for data storage, such as NOR Flash, with a capacity of 128MB. After deducting the code programs required for TWS earbud functions, such as the bootloader, OTA upgrade, noise cancellation, and touch control executable code, there is still ample 80MB of space left to store the real-time temperature and humidity data collected by the temperature and humidity sensing module.

[0029] This invention, through a temperature and humidity sensing module 2, a main control circuit board 4, and a charging connection terminal 5, enables collaborative operation between the TWS earphone charging case 6, the TWS earphones, and a mobile app. It achieves real-time acquisition, processing, temporary storage, and transmission of environmental temperature and humidity data. Users can conveniently obtain temperature and humidity information via the mobile app without relying on the local display in the charging case, overcoming the limitation of existing technologies where data can only be displayed locally in the charging case, thus improving data accessibility and utilization efficiency. Furthermore, the electrical connections between components and a rational structural design ensure the stability and reliability of data transmission, providing users with an intelligent and convenient temperature and humidity monitoring experience.

[0030] In this embodiment, a rechargeable battery 7 is built into the bottom of the charging case body 1. The rechargeable battery 7 is electrically connected to the main control circuit board 4. The TWS earbuds 6 are electrically connected to the main control circuit board 4 through the charging connection terminal 5 to obtain power from the rechargeable battery 7. The rechargeable battery 7 built into the bottom of the charging case body 1 and the main control circuit board 4 form a power supply circuit, providing power support for the entire charging case system and the TWS earbuds 6. When the TWS earbuds 6 are placed in the charging case, the earbuds' charging interface makes physical contact with the charging connection terminal 5 on the main control circuit board 4 and establishes an electrical connection. The power from the rechargeable battery 7 is regulated by the circuit of the main control circuit board 4 and transmitted to the battery of the TWS earbuds 6 through the charging connection terminal 5, realizing the charging process of the earbuds. During this process, the charging connection terminal 5 has dual functions of power transmission and data transmission, both replenishing the power of the earbuds and synchronously transmitting the temperature and humidity data processed by the MCU in the main control circuit board 4 to the earbuds' storage module for temporary storage.

[0031] In a preferred embodiment, the charging case body 1 has an independent partition compartment 13 on one side of its top, and the temperature and humidity sensing module 2 is built into the partition compartment 13. Furthermore, the charging case body 1 has a ventilation window 131 corresponding to the partition compartment 13 to ensure that the temperature and humidity sensing module 2 is connected to the external environment. The independent partition compartment 13 on one side of the top of the charging case body 1 provides dedicated installation space for the temperature and humidity sensing module 2. The partition compartment 13 is connected to the external environment through the ventilation window 131 on the housing, ensuring that air can freely flow into the partition compartment 13. The temperature and humidity sensing module 2 is fixedly installed inside the partition compartment 13, with its sensing surface facing the ventilation window 131. It is electrically connected to the main control circuit board 4 through the partition compartment 13 via a flexible circuit board 3. When the temperature and humidity of the external environment change, air enters the partition compartment 13 through the ventilation window 131, directly acting on the sensitive element of the temperature and humidity sensing module 2, causing it to generate a corresponding physical signal change. After conversion, the signal is transmitted to the MCU of the main control circuit board 4 for processing via the flexible circuit board 3. The independent compartment 13 physically isolates the temperature and humidity sensing module 2 from the heat-generating components (such as the rechargeable battery 7 and the main control circuit board 4) in the charging compartment, reducing the interference of internal heat sources on the detection data.

[0032] In this embodiment, the charging case body 1 includes a top compartment 11 and a bottom compartment 12. The top compartment 11 has a receiving slot for placing TWS earphones 6, and the bottom compartment 12 has a battery compartment for installing rechargeable batteries 7. The main control circuit board 4 is fixedly installed between the top compartment 11 and the bottom compartment 12, and one end of the charging connection terminal 5 is electrically connected to the main control circuit board 4, while the other end passes through the receiving slot of the top compartment 11.

[0033] The charging case body 1 is divided into a top compartment 11 and a bottom compartment 12. The receiving slot of the top compartment 11 is precisely adapted to the shape of the TWS earbuds 6, ensuring that the charging interface and the charging connection terminal 5 (pogopin probe) are accurately aligned when the TWS earbuds 6 are placed. One end of the charging connection terminal 5 is fixed to the main control circuit board 4 by soldering or plugging, and the other end passes through the top compartment 11 and extends to a designated position in the receiving slot. The battery compartment of the bottom compartment 12 uses an embedded or snap-on structure to fix the rechargeable battery 7, and is electrically connected to the power management module of the main control circuit board 4 through wires to form a complete power supply circuit. When the TWS earbuds 6 are placed in the receiving slot, the charging contacts at the bottom of the earbuds contact the charging connection terminal 5. The main control circuit board 4 transmits electrical energy from the rechargeable battery 7 to the earbuds through the charging connection terminal 5, and at the same time transmits the temperature and humidity data processed by the MCU to the earbud storage module.

[0034] In this embodiment, a cover 14 (not shown in the figure) is detachably connected to the top of the charging case body 1. An opening detection component is provided between the cover 14 and the charging case body 1. The opening detection component is connected to the main control circuit board 4 and is used to detect the opening and closing state of the cover 14. When the cover 14 is opened, the main control circuit board 4 triggers the TWS earphone 6 to establish a Bluetooth communication connection with the mobile phone.

[0035] Specifically, the top of the charging case body 1 is connected to the lid 14 via a hinge, snap-fit, or magnetic structure, enabling it to open and close. The lid opening detection component can be a Hall sensor or a micro switch. This component is installed on the lid 14, and its signal output is electrically connected to the main control circuit board 4 via a wire or another flexible circuit board 3. When the user opens the lid 14, the relative position of the lid 14 and the charging case body 1 changes, triggering the detection component to generate an electrical signal. For example, the Hall sensor outputs a high or low level signal due to a change in the magnetic field. This signal is transmitted to the main control circuit board 4, where the MCU interprets it as an "opening command" through a preset program and then sends a trigger signal to the TWS earbuds 6. Upon receiving the signal, the TWS earbuds 6 automatically wake up the Bluetooth module, scan for and connect to paired mobile devices, and establish a Bluetooth communication link. The coordinated design of the lid opening detection component and the main control circuit board 4 enables automated triggering of the TWS earbuds 6's Bluetooth connection. Data transmission is activated the instant the lid is opened without manual user intervention, significantly improving ease of use.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
