[0027] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.
[0028] The specific implementation process of this utility model is as follows:
[0029] like Figures 1 to 9 As shown, a multifunctional power bank speaker includes an upper shell 1 and a bottom shell 2 that cooperate with each other. A receiving groove 3 and a V-shaped groove 4 are formed at the top of the upper shell 1. The receiving groove 3 is located on one side of the V-shaped groove 4. The receiving groove 3 is used to accommodate a wireless charging panel 5. The side end of the wireless charging panel 5 is rotatably connected to the inner wall of the bottom shell 2. A circuit board, a lithium battery, and a speaker are provided on the bottom shell 2. The circuit board includes an MCU, a power management IC, a Bluetooth audio SOC, a wireless charging module, a USB interface, a charging switch key 7, and an audio control button. The MCU is respectively connected to the power management IC, the Bluetooth audio SOC, the wireless charging module, and the charging switch key 7. The Bluetooth audio SOC is respectively connected to the speaker and the audio control button. The power management IC is respectively connected to the lithium battery and the USB interface, and the wireless charging module is connected to the lithium battery.
[0030] Specifically, the upper and lower shells 1 and 2 are connected to form the power bank body. A receiving groove 3 formed at the top of the upper shell 1 accommodates the wireless charging panel 5. The side of the wireless charging panel 5 is pivotally connected to the inner wall of the bottom shell 2, allowing the wireless charging panel 5 to move freely along the rotational direction. When needed to support a mobile phone, the wireless charging panel 5 can be erected and unfolded, forming a mobile phone holder in conjunction with the V-shaped groove 4. The holder's angle can be adjusted freely along the rotational direction. When the wireless charging panel 5 is no longer needed as a mobile phone holder, it is rotated and stored in the receiving groove 3. The power bank body houses a circuit board, a lithium battery, and a speaker for audio playback. The circuit board integrates an MCU, a power management IC, a Bluetooth audio SoC, a wireless charging module, a USB port, a charging switch 7, and audio control buttons. The lithium battery provides power to charge audio and electronic devices, while the power management IC manages the battery's charge and discharge. When the battery is low, an external input voltage can be used to charge the battery through the USB port. When the lithium battery is fully charged, it can be used to charge electronic devices via the USB port. The USB port can be either Type-C or USB-C, depending on the user's needs, allowing for charging electronic devices without wireless charging. Wireless charging is also supported. The wireless charging module is connected to the MCU and the lithium battery. When the wireless charging module detects a chargeable load, it quickly activates the wireless charging function to charge the wireless load. The wireless charging module is connected to a wireless charging transmitter coil, which is integrated into the wireless charging panel 5. This integrated wireless charging transmitter coil transmits power to the load, enabling wireless charging regardless of whether the stand is in use. The wireless charging panel 5 also features a magnetic attraction to enhance positioning stability. When a phone is placed on the stand, a phone that supports wireless charging can be charged directly through the power bank's wireless charging function. Users can also use their phone to watch videos, listen to audio, or perform other operations while charging. The Bluetooth audio SOC is connected to the MCU, audio control buttons, and speaker. The audio control buttons include an audio power button 8 and function adjustment buttons. The MCU receives commands from the audio power button 8 to turn the device on and off and wake up the Bluetooth speaker. The Bluetooth audio SoC supports wireless connection with Bluetooth devices such as mobile phones and computers for audio data transmission. It also supports TF card access, reading and playing audio files from the card, providing users with a variety of playback options. Function adjustment buttons allow users to operate the Bluetooth speaker. You can power it on and off by pressing and holding the POWER / MODE button; switch between Bluetooth and TF card functions by briefly pressing the POWER / MODE button; select a song by pressing and holding the buttons; increase or decrease the volume by pressing and holding the buttons; and play or pause a song by pressing the PLAY / PAUSE button. The specific audio control buttons can be adjusted based on actual development and needs.The power bank in this embodiment is equipped with a 5000mah lithium battery, and can also be equipped with 10000mah or 20000mah batteries according to actual needs.
[0031] This application can provide wired charging for a variety of electronic devices through a USB interface, meeting the basic needs of users for power banks. By integrating the Bluetooth audio function on the basis of the power bank, the Bluetooth audio supports two playback modes: Bluetooth wireless and TF card. By designing a V-shaped groove 4 and a rotatably connected wireless charging panel 5 on the power bank shell, a mobile phone holder that is foldable and adjustable to any angle is formed, which can provide wireless charging function for electronic devices and also has the practicality of a mobile phone holder. By integrating a power bank with wired external charging and wireless charging functions, a Bluetooth audio function, and a mobile phone holder function into one, a multifunctional power bank speaker with rich functions, compact size, portability, and practicality is provided.
[0032] In an embodiment of the present utility model, a lithium battery protection IC is connected between the power management IC and the lithium battery. By monitoring parameters such as the voltage, current and temperature of the lithium battery, measures are immediately taken to protect the lithium battery when an abnormal situation is detected, so that the lithium battery is protected from damage by abnormal situations such as overcharging, over-discharging and short circuit, thereby extending the service life of the power bank.
[0033] In an embodiment of the present invention, the circuit board also includes a power display module, which is connected to the MCU. The power display module facilitates the user to understand the remaining power of the power bank in real time. When the charging switch key 7 is short-pressed, the MCU receives a trigger signal, then obtains the current remaining battery power and sends the power information to the power display module. The power display module adjusts the display status based on the received power information, such as lighting a corresponding number of LED indicators or updating the power percentage on the LCD screen. Waking up the power display also wakes up the wireless charging function.
[0034] In the embodiment of the present invention, a button hole 6 is provided at the side end of the upper shell 1 , and a charging switch 7 and an audio control button are fixedly installed in the button hole 6 .
[0035] In an embodiment of the present invention, a sound hole 9 is further provided at the top of the upper shell 1. The sound hole 9 is located on the other side of the V-shaped groove 4. The sound hole 9 is arranged opposite to the speaker. The sound played by the audio is transmitted through the speaker and diffused into the external environment through the sound hole 9.
[0036] In other embodiments, a solar charging panel (not shown in the figure) can also be set at the bottom of the bottom shell 2. The solar charging panel is connected to the power management IC. The solar charging panel is used to power the lithium battery. The power management IC intelligently controls the charging process to ensure that the battery can safely and efficiently receive and store electrical energy.
[0037] The above-described embodiments merely represent implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
