Technical Field

[0001] This utility model relates to an electronic product, specifically a portable multi-functional wireless point-to-point display device for children. Background Technology

[0002] With the development of consumer electronics technology, portable electronic devices with image acquisition, wireless transmission, and display functions are being used more and more widely in daily home use. Especially in non-medical scenarios such as child care, daily observation, and parent-child interaction, users have placed higher demands on the safety, portability, and ease of operation of these devices.

[0003] In existing technologies, products used for observing the ear canal or similar confined spaces typically work in conjunction with mobile terminals, transmitting captured images or videos via a wireless camera to external devices such as smartphones or tablets for display. These products generally rely on applications for connection and operation, requiring prior software download and installation. They are also susceptible to issues related to system compatibility, network conditions, and application stability, making the process relatively complex, especially in scenarios involving children or multiple family members sharing the device. This results in a high barrier to entry and a poor user experience.

[0004] Furthermore, most existing related products are single-function, with their displays typically used only for real-time image display. When not in use, they fail to fully realize their value, resulting in low utilization and high idle rates. Additionally, some display devices are not designed with children's needs in mind, lacking anti-slip, anti-fall, and flexible cushioning features, posing certain safety hazards during daily use.

[0005] On the other hand, as families increase their demand for recording children's growth and parent-child interaction, digital photo frame products are gradually entering family life. However, most existing digital photo frames are standalone products with relatively simple functions and lack effective integration with image acquisition devices. This results in families needing to configure multiple electronic devices separately, which not only increases costs but also hinders centralized management and use of the devices.

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0026] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0027] like Figures 1-3 As shown, a specific embodiment of the portable multifunctional wireless point-to-point display device for children according to the present invention is as follows. This display device is used for ear canal observation and ear-picking aid display in children's home settings, while also functioning as a digital photo frame for image display. The overall structure adopts a combined structure of "device body 1 + ear-picking pen holder 4," achieving real-time image / video transmission through point-to-point wireless direct connection without application mediation. After mode switching, it can independently call locally stored images for static or carousel display, thus realizing two different display applications on the same hardware platform.

[0028] The display device of this embodiment includes a device body 1, with an internal mounting cavity for accommodating electronic components such as a main board PCBA 8, a display driver circuit, a wireless point-to-point connection module, a storage module, a power supply module, and a charging port main board 7 that mates with an external charging interface. The device body 1 is formed by assembling a front cover 13 and a rear cover 12, which are fixed together by means of snaps, screws, or ultrasonic welding to ensure a secure assembly and protect the internal circuitry.

[0029] To accommodate children's grip and home use, the main body 1 of the device is covered with a silicone sleeve 14, preferably made of food-grade silicone. The outer surface of the silicone sleeve 14 has an anti-slip texture to improve grip stability, and thickened cushioning sections are provided in easily bumped areas to improve drop resistance and reduce the probability of structural damage from drops. A connecting sleeve 5 is further provided on the back of the silicone sleeve 14. The connecting sleeve 5 is used to insert and position the ear spoon pen 4, so as to realize the storage and anti-loss of the ear spoon pen 4 when not in use. The connecting sleeve 5 and the silicone sleeve 14 can be integrally molded or assembled. The inner wall of the connecting sleeve 5 can be provided with limiting ribs or elastic holding structures to increase friction and positioning stability after insertion.

[0030] The main body 1 of the device has a display component 3 installed at the front end. The display component 3 includes a display screen and a display driving circuit electrically connected to the display screen. The display screen is preferably a circular display screen 11. A screen cover 10 is provided on the outside of the circular display screen 11. The screen cover 10 is used to protect the surface of the display screen from scratches, dust, and sweat intrusion, and can also serve as a decorative frame to enhance the overall appearance.

[0031] The circular display screen 11 is fixedly mounted on the main body 1 of the device via a screen bracket 9. The screen bracket 9 provides structural support, positioning, and a mounting surface. The screen bracket 9 can be integrally formed with the front cover 13 or formed separately and then assembled. The size of the circular display screen 11 can be selected according to the product positioning, for example, set in the range of 1.38 inches to 5 inches, to balance portability and display visibility.

[0032] The display driver circuit is used to receive and parse display signals from the wireless point-to-point connection module or storage module, and execute different display logic according to the current working mode. When the signal type is real-time video / image stream, the display driver circuit drives the display screen to enter the real-time video display logic. When the signal type is local image data, the display driver circuit drives the display screen to enter the frame image display logic, thereby realizing the switching and adaptation of the same display screen between real-time display and frame display.

[0033] A button assembly 2 is located on the side of the main body 1. The button assembly 2 includes at least a power button and a mode switching button. The power button is used to power on, power off, or wake up / sleep. The mode switching button is used to switch between the ear pick display mode and the digital photo frame display mode. For ease of use by children and families, the buttons can be a raised physical button structure, or a waterproof and dustproof press-triggered structure can be formed within the corresponding pressing area of ​​the silicone sleeve 14. The button trigger signal is input to the main board PCBA8, and the main control logic determines the function corresponding to different operations such as short press and long press. For example, a short press of the mode switching button is used to switch modes, and a long press of the power button is used to power off. Alternatively, a touch operation area or touch logic can be set on the display screen for operations such as page turning, pausing slideshow, and entering settings in digital photo frame mode. When touch or button operation is detected, it can trigger wake-up and refresh of the display.

[0034] The wireless point-to-point connection module is integrated into the mounting cavity and electrically connected to the display driver circuit. It establishes a point-to-point wireless connection with the transmitter without application-mediated communication to receive and transmit display signals. This module includes a point-to-point communication chip, which can use Bluetooth 5.3 or Wi-Fi Direct to achieve direct point-to-point connection. To enhance user experience, the point-to-point communication chip is equipped with an automatic pairing and reconnection mechanism. Specifically, after the main device 1 is powered on and enters the ear pick display mode, the point-to-point communication chip automatically broadcasts or enters a pairing scan state. When the ear pick pen 4 is powered on, its wireless transmission module automatically initiates a pairing request or broadcasts identification information. After the main device 1 recognizes the preset pairing information, it automatically establishes a point-to-point connection. If signal obstruction, increased distance, or insufficient power causes the link to disconnect during use, the main device 1 and the ear pick pen 4 automatically re-establish the connection and resume image / video transmission according to the reconnection mechanism, eliminating the need for repeated complex operations by the user. The electrical connection between the wireless point-to-point connection module and the display driver circuit can be achieved through the data bus or interface on the motherboard PCBA8, such as a serial interface, SPI interface, USB interface or other adapter interface, to ensure that the display data can be stably transmitted to the display driver circuit for display output.

[0035] The ear spoon pen 4, which is wirelessly connected point-to-point with the main body 1, serves as the transmitter component. The ear spoon pen 4 is detachably connected to the main body 1. The detachable connection can be achieved by inserting and removing the connecting sleeve 5 for positioning, or by using a snap-fit ​​structure, a magnetic structure, or a plug-in interface structure. In this embodiment, the ear spoon pen 4 is inserted into the connecting sleeve 5 on the back of the silicone sleeve 14 for positioning when stored, and can be held and used independently after being removed.

[0036] The ear pick pen 4 has a slender, rod-like structure, conforming to the operating habits of ear picks and facilitating entry into the ear canal area. Inside the ear pick pen 4 is a camera module, a supplementary lighting component, a battery, and a wireless transmission module. The ear pick head is located at the front end of the ear pick pen 4. The camera module is positioned close to the ear pick head so that its field of view covers the area of ​​action of the ear pick head and the internal area of ​​the ear canal, enabling real-time observation with a "what you see is what you get" effect during ear picking. The supplementary lighting component, preferably a ring-shaped LED supplementary light, surrounds the camera module to illuminate the shooting area when the ambient light in the ear canal is insufficient, allowing the camera module to acquire clearer images or videos of the ear canal in low-light environments.

[0037] The ring-shaped LED fill light can be powered by a constant current drive to ensure stable brightness and reduce flicker; the fill light intensity can be set to a fixed level, or it can be automatically adjusted in the main control logic according to the ambient brightness or image exposure parameters. The battery inside the ear spoon pen 4 is used to power the camera module, fill light component and wireless transmission module. The battery can be a rechargeable battery 6 and can be recharged through an independent charging structure or by sharing a charging structure with the main body of the device 1, depending on the structural space and cost.

[0038] The wireless transmission module inside the ear spoon pen 4 is set up one-to-one with the wireless point-to-point connection module inside the main body of the device, and is used to send the ear canal image or video signal collected by the camera module to the display component 3 of the main body of the device in a point-to-point manner for display in real time.

[0039] In actual operation, after the ear spoon pen 4 is powered on, the camera module begins to collect image or video signals. After the collected signals are encoded, cached or formatted inside the ear spoon pen 4, they are sent by the wireless transmission module in a point-to-point manner. The wireless point-to-point connection module of the main body 1 receives the image or video signal and transmits it to the display driving circuit. The display driving circuit drives it to be displayed on the circular display screen 11, thereby realizing real-time display at the end of the main body 1.

[0040] To reduce latency and ensure real-time performance, a higher bandwidth and lower latency transmission channel can be set when using Wi-Fi Direct, and an appropriate video transmission compression format or packetization mechanism can be used when using Bluetooth 5.3 to ensure image continuity and usable clarity.

[0041] The storage module is integrated within the mounting cavity and electrically connected to the display driver circuitry, used to store or retrieve image data for display within the photo frame. The storage module may include an image storage area and / or a TF card expansion interface.

[0042] The image storage area can be onboard memory or internal storage space of the main control chip, used to store preset images or images written by the user; the TF card expansion interface is used to insert a TF card to expand the image capacity, allowing users to read and display more image data in digital photo frame display mode. The electrical connection between the storage module and the display driver circuit can be realized through the motherboard PCBA8 to read and transmit data. The display driver circuit decodes the image data according to the format and outputs it to the display screen.

[0043] The power module includes a rechargeable battery 6, which powers the display component 3, the wireless peer-to-peer connection module, and the storage module. The power module is electrically connected to the charging port motherboard 7 to enable charging.

[0044] The charging port motherboard 7 is electrically connected to the external charging interface, which can be located on the side or bottom of the main body 1 of the device for easy charging with a standard charging cable.

[0045] The charging port motherboard 7 is used to implement charging management and input protection, such as limiting the charging current, protecting the battery from overcharge, and protecting the external power input from overvoltage and overcurrent. When the external power is connected, the power module can supply power to the system and charge the rechargeable battery 6 at the same time. When the external power is disconnected, the rechargeable battery 6 will continue to supply power to the system, thereby ensuring the device is portable.

[0046] The power module can also feed back battery power information to the motherboard PCBA8, which will then display a power level indicator on the screen or prompt the user to charge when the battery is low.

[0047] In terms of specific mode control, the mode switching key is used to switch the display device between ear pick display mode and digital photo frame display mode.

[0048] In ear pick display mode, the main body 1 prioritizes the wireless point-to-point connection module and enters automatic pairing / connection mode. Simultaneously, the display driver circuit enters real-time video display logic. When the ear pick pen 4 successfully connects and begins sending image or video signals, the display component 3 displays the image or video signal sent by the ear pick pen 4 in real time. Users can operate the ear pick head while observing the screen, thus improving the controllability and safety of the ear pick process. In digital photo frame display mode, the main body 1 disables or reduces the priority of the wireless point-to-point connection module. The display driver circuit switches to photo frame image display logic, and the display component 3 calls the image data from the storage module for static display or carousel display. The carousel display can automatically switch to the next image at preset intervals, or it can be manually switched via button or touch operation.

[0049] To further reduce power consumption and improve battery life, in digital photo frame display mode, the display device supports automatically entering sleep mode after a preset period of inactivity. Inactivity may include no detected button presses, no detected touch operations, or no detected specific interactive events.

[0050] After entering hibernation mode, the display backlight can be turned off or the processor frequency can be reduced to decrease power consumption. When a button or touch operation is triggered, the system wakes up and resumes display output, while continuing the carousel display or returning to the previous display screen. This hibernation and wake-up logic can be executed by the motherboard PCBA8, or it can be implemented in conjunction with the display driver circuit and the main control logic.

[0051] In terms of structural assembly and connection, the mainboard PCBA8 inside the main body 1 integrates a point-to-point communication chip, a storage module interface, a power management circuit, and a connection interface with the display driver circuit. It also handles system logic such as key input recognition, mode status management, sleep / wake-up control, and image carousel control. The display driver circuit is electrically connected to the display screen and is responsible for display timing and drive output.

[0052] The wireless point-to-point connection module is electrically connected to the display driver circuit, enabling the wirelessly received data to be retrieved and displayed in real time. The storage module is also electrically connected to the display driver circuit, allowing image data to be retrieved and displayed in a frame. The power module supplies power to the mainboard PCBA8, display component 3, wireless point-to-point connection module, and storage module respectively. The charging port mainboard 7 connects to the external charging interface to achieve charging management and power supply switching.

[0053] In actual use, the user first turns on the main body of the device 1 using the power button. After the system is powered on, it can default to the ear pick display mode or remember the previous mode and enter the corresponding mode. In the ear pick display mode, the main body of the device 1 activates the wireless point-to-point connection module and attempts to establish a point-to-point direct connection with the ear pick pen 4. After the ear pick pen 4 is powered on, the camera module captures images of the ear canal. The ring LED fill light provides supplementary lighting when there is insufficient light in the ear canal. The captured images or videos are transmitted point-to-point to the main body of the device 1 through the wireless transmission module. The main body of the device 1 displays the screen in real time to assist the user's operation. When it is necessary to switch to the digital photo frame function, the user presses the mode switch button, and the main body of the device 1 enters the digital photo frame display mode and reads image data from the image storage area or TF card for static display or carousel display. The device automatically goes into sleep mode when not in use for extended periods and wakes up to resume display when triggered by a button or touch. It combines wireless point-to-point direct connection with local storage to perform both real-time display and frame display functions without application intervention. The disclosed content covers various technical aspects, including the main body structure (1), the composition and assembly of the display components (3), the point-to-point connection mechanism, the internal hardware configuration of the ear-spoon pen (4), the supplementary lighting method, the button and mode switching logic, the storage retrieval and carousel strategy, the sleep / wake-up strategy, the silicone sleeve (14) protective structure, and the charging and power supply structure. This meets the requirements for sufficient disclosure and feasibility.

Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
