Description

Technical Field

[0001] This utility model relates to the field of Bluetooth technology, and in particular to a Bluetooth control box and its PCBA module. Background Technology

[0002] A Bluetooth control box is a control device that uses Bluetooth technology for wireless communication, allowing users to remotely operate and control other devices via Bluetooth connection. Bluetooth control boxes typically have device pairing capabilities, enabling them to pair with multiple devices and facilitating convenient switching and control between different devices.

[0003] Bluetooth control boxes typically house Bluetooth PCBA modules. A Bluetooth PCBA board usually consists of key components such as a Bluetooth main control chip, an oscillation frequency provider, a power and charging management chip, an audio power amplifier chip, and an RF antenna. These components work together to enable the Bluetooth PCBA board to receive and transmit Bluetooth signals, process digital signals, and convert digital signals into analog signals for audio output. However, the existing layered design between Bluetooth devices and PCBA modules is not clearly defined, and the internal space allocation of the control box is not reasonable, occupying a large amount of space. Furthermore, the stacking of circuit boards and Bluetooth components with different functions within the control box is not conducive to later maintenance and replacement. Therefore, this paper proposes an improved Bluetooth control box and its PCBA module. Utility Model Content

[0010] The above technical solution provides installation space for the relevant Bluetooth components and protects them from damage caused by accidental contact with external objects. It can be made of engineering plastics, metals, or other materials. Engineering plastics offer advantages such as lightweight, low cost, and ease of processing and molding, while metals provide stronger protection, better heat dissipation, and a more aesthetically pleasing appearance. A display component is installed on the control box to show the Bluetooth control box's operating status, such as battery level and whether it is powered on. The display component shows the operating status of the Bluetooth control box or its connected devices. Ventilation holes are provided on the side of the control box to facilitate the dissipation of heat generated by the internal Bluetooth components, promoting their long-term use. Several ventilation holes are located on different sides of the control box to ensure rapid heat dissipation from all parts of the box.

[0011] Preferably, in any of the above embodiments, the bottom end of the control box side plate is provided with a groove, and the bottom plate is fixedly connected to the groove by a locking bolt.

[0012] Preferably, of any of the above solutions, there are several receiving slots that are evenly arranged in the thickness direction of the control box, and the rotating shaft is a damped rotating shaft.

[0013] The above technical solution employs the following: a base plate is used to seal the bottom surface of the control box. A receiving slot is created inside the control box, providing installation space for the rotating shaft and storage space for the mounting plate. The mounting plate is rotatably connected to the receiving slot via the rotating shaft, allowing it to be rotated out or retracted as needed. The mounting plate provides an installation platform for the Bluetooth motherboard and functional circuit boards. Several receiving slots are evenly arranged inside the control box, facilitating the layered installation of circuit boards with different functions. The rotating shaft uses a damping shaft, allowing it to automatically and easily fix itself after being turned, facilitating the adjustment of the mounting plate's position.

[0014] A PCBA module for a Bluetooth control box includes a Bluetooth motherboard and a functional circuit board, both of which have mounting holes at their corners.

[0015] Preferably, in any of the above solutions, the Bluetooth motherboard and the functional circuit board are both fixedly connected to the mounting plate by bolts, and the Bluetooth motherboard and the functional circuit board are respectively fixed on different mounting plates.

[0016] The above technical solution provides a mounting platform for key components such as the Bluetooth main control chip, oscillation frequency supply components (e.g., quartz crystal oscillator), power and charging management chips, audio power amplifier chips, and RF antennas. The functional circuit boards provide mounting platforms for related functional components. Mounting holes are provided at the ends of both the Bluetooth main board and the functional circuit boards to facilitate their mounting on the mounting plates.
