Description

Technical Field

[0001] This invention relates to the field of ring technology, and in particular to a ring with Bluetooth recording function. Background Technology

[0002] Currently, there are various styles of recording devices (such as voice recorders) on the market, but their functions are relatively limited, and these devices are also quite bulky, making them inconvenient to carry around. With the advancement of technology, smart rings with recording functions are gradually emerging.

[0003] Referring to Chinese patent document CN119745170A, a smart ring with recording function is disclosed, including a ring case, a clamping groove on the front of the ring case, a clamping mechanism inside the clamping groove, a limiting ring on the clamping mechanism, and an adjusting gear ring rotatably connected between the limiting ring and the clamping mechanism. The adjusting gear ring is drivenly connected to the clamping mechanism. The inner side of the ring case has a battery cavity and a mounting cavity. The battery cavity contains several arc-shaped batteries, and the mounting cavity contains functional modules such as a microphone, an electronic control board, and a Bluetooth module. The rear side of the ring case has a ring cover, and a touch screen is installed inside the screen mounting slot. However, all functional modules of the ring disclosed in this patent document, such as the microphone, electronic control board, Bluetooth module, and arc-shaped batteries, need to be inserted from the rear of the battery cavity and mounting cavity inside the ring case, and then the ring cover is placed on the rear of the ring case. The outer side of the ring case cannot be opened. This installation structure and method makes the installation of each functional module very inconvenient and the installation stability poor. After the ring cover is closed, it still needs to be fixed with screws. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a ring with Bluetooth recording function. The inner ring bracket and the outer ring bracket are fixed by the inner and outer cover and the end snap-fit, which makes the installation of the inner ring bracket and the outer ring bracket very convenient and stable, without the need for screw fixing. Furthermore, with the assistance and support of the middle bracket, the installation of PCBA circuit board, battery module and button is very convenient and stable.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a ring with Bluetooth recording function, comprising an inner ring support, an outer ring support, a middle support, a PCBA circuit board, a button, and a battery module. The inner ring support includes an integrally connected inner ring support and a "C"-shaped groove, with the inner ring support located between the two ends of the "C"-shaped groove. The middle support includes a main support and a secondary support, with the main support mounted on the inner ring support and the secondary support extending into one end of the "C"-shaped groove. A portion of the PCBA circuit board is mounted within the middle support, and another portion of the PCBA circuit board extends into the other end of the "C"-shaped groove. The PCBA circuit board is equipped with a Bluetooth chip, a function switch, and a microphone. The Bluetooth chip... The device is electrically connected to a function switch and a microphone. The function switch is located in the main support of the central bracket, and the microphone is located in the secondary support of the central bracket. The outer ring bracket is C-shaped and covers the C-shaped groove of the inner ring bracket. The outer ring bracket has a microphone hole corresponding to the microphone. The two ends of the C-shaped groove are respectively provided with a first latching part, and the two ends of the outer ring bracket are respectively provided with a second latching part. The first latching part and the second latching part are engaged with each other. The button is installed on the main support of the central bracket and is pressed to engage with the function switch of the PCBA circuit board. The battery module is installed in the C-shaped groove of the inner ring bracket and is electrically connected to the PCBA circuit board.

[0006] The beneficial effects of this invention are as follows: During assembly, the main support of the middle bracket is first installed on the inner ring support, and the secondary support extends into one end of the "C"-shaped groove. Then, the PCBA circuit board is installed on the middle bracket and the other end of the "C"-shaped groove. Next, the battery module is installed inside the "C"-shaped groove of the inner ring bracket. Then, the outer ring bracket is covered over the "C"-shaped groove of the inner ring bracket, and the second snap-fit ​​part of the outer ring bracket is snapped and fixed with the second snap-fit ​​part of the "C"-shaped groove. Finally, the button is installed, and the assembly of the main components is completed. It can be seen that the inner ring bracket and outer ring bracket of this invention are very convenient to install and have good stability through the inner and outer cover and end snap-fit ​​fixing method. No screw fixing is required. With the assistance and support of the middle bracket, the installation of the PCBA circuit board, battery module and button is very convenient and stable.

[0007] In the above technical solution, the battery module includes a positive nickel plate, a negative nickel plate, and multiple button batteries. The multiple button batteries are continuously arranged along the "C"-shaped groove of the inner ring support. The positive nickel plate is welded to the positive electrode of each of the multiple button batteries, and the negative nickel plate is welded to the negative electrode of each of the multiple button batteries, forming a parallel connection between the multiple button batteries. The positive and negative nickel plates are electrically connected to the PCBA circuit board. This invention, by connecting multiple continuously arranged button batteries in parallel, can significantly improve the ring's battery life, enabling the ring to record audio for extended periods.

[0008] In the above technical solution, adhesive backing sheets are respectively provided inside the inner ring support and the "C"-shaped groove of the inner ring bracket. The battery module, the middle bracket, and the PCBA circuit board are respectively bonded to the inner ring bracket using the adhesive backing sheets. By providing adhesive backing sheets, this invention can more securely install and position the battery module, the middle bracket, and the PCBA circuit board.

[0009] In the above technical solution, the first snap-fit ​​part is a snap-fit ​​hole, and two snap-fit ​​holes are respectively provided at both ends of the "C"-shaped groove. The second snap-fit ​​part is a snap-fit ​​hook, and two snap-fit ​​hooks are respectively provided at both ends of the outer ring bracket. When assembling the outer ring bracket, the outer ring bracket is first elastically opened and moved to the outside of the "C"-shaped groove of the inner ring bracket. Then, using the elasticity of the outer ring bracket itself, the outer ring bracket covers the outside of the "C"-shaped groove of the inner ring bracket, and the snap-fit ​​hooks are snapped into the corresponding snap-fit ​​holes. Finally, glue is applied to seal the junction of the outer ring bracket and the "C"-shaped groove. Because the outer ring support is C-shaped and has elasticity, when the two snap hooks at both ends of the outer ring support are respectively snapped into the two upper snap holes at both ends of the C-shaped groove of the inner ring support, it can, on the one hand, position the two ends of the C-shaped groove of the outer ring support and the inner ring support, and on the other hand, allow the outer ring support to tightly hug the C-shaped groove of the inner ring support using its own elasticity and cover it with the C-shaped groove. The glue sealing method at the cover can increase the sealing effect and achieve good waterproofing.

[0010] In the above technical solution, side grooves are provided on both sides of the "C"-shaped groove, and side strips are provided on both sides of the outer ring bracket, with the side strips installed within the side grooves. The connection and cooperation between the "C"-shaped groove of the inner ring bracket and the outer ring bracket of the present invention, through the side grooves and side strips, achieves a stable cover and further improves the sealing and waterproofing effect.

[0011] In the above technical solution, the PCBA circuit board includes a PCBA main body, one end of which is connected to a first PCBA sub-part, and the other end of which is connected to a second PCBA sub-part. The PCBA main body is installed within a main bracket, the first PCBA sub-part is installed within a secondary bracket, and the second PCBA sub-part extends into the other end of a "C"-shaped groove. The function switch is soldered to the upper side of the PCBA main body, the Bluetooth chip is soldered to the lower side of the PCBA main body, the microphone is soldered to the upper side of the first PCBA sub-part, and the battery module is connected to the second PCBA sub-part via a wire. Preferably, the main bracket of the middle bracket has a clearance hole, the Bluetooth chip extends into the clearance hole, and an EVA gasket is provided between the Bluetooth chip and the inner ring support. The PCBA circuit board of the present invention adopts a three-part structure design, which allows the three parts to be installed in different positions of the ring to make reasonable use of the internal space of the ring. Furthermore, it allows for the partitioned installation of components such as the function switch, microphone, Bluetooth chip, battery management chip, and storage chip. The Bluetooth chip, inner ring support, and EVA gasket of this invention are interference fit, which increases the installation stability of the PCBA main body.

[0012] In the above technical solution, a silicone microphone sleeve is installed inside the secondary support of the central support. The silicone microphone sleeve is installed outside the microphone and has a sound passage hole. A waterproof mesh is provided between the silicone microphone sleeve and the outer ring support. By setting the silicone microphone sleeve and the waterproof mesh, the microphone hole can have a good sealing and waterproof effect.

[0013] In the above technical solution, the button includes a PC material button bracket, a silicone material button shell, and a PC material keycap. The PC material button bracket is mounted on the main bracket of the central bracket, and a through cavity is provided in the middle of the PC material button bracket. The silicone material button shell is located outside the PC material button bracket, and the PC material keycap is located on the inner side of the middle of the silicone material button shell. When the silicone material button shell is pressed, it can push the PC material keycap downward to press the function switch. Conductive foam is provided between one end of the PC material button bracket and the PCBA circuit board. The conductive foam is electrically connected to the PCBA circuit board to serve as an antenna. This structure provides good elasticity and feel when the button is pressed, good sealing and waterproofing, and space for accommodating the conductive foam antenna.

[0014] In the above technical solution, the PC material key bracket and PC material keycap are respectively manufactured with the silicone material key shell through a two-color molding process. The PC material key bracket and silicone material key shell simultaneously cover both ends of the outer ring bracket, and the connection between the key and the middle bracket and the outer ring bracket is sealed with adhesive. This structure enables the PC material key bracket and PC material keycap to be tightly connected to the silicone material key shell, and achieves a good sealing and waterproof effect between the key and the middle bracket and the outer ring bracket.
