Technical Field
[0001] The utility model relates to the technical field of Bluetooth finders, in particular to a precise positioning mechanism for a Bluetooth finder. Background Art
[0002] In daily life, people often leave small items such as wallets and keys lying around, which results in a lot of time spent searching for them when they are needed. To address this, people have invented Bluetooth finders, which can be hung on a keychain or placed in a wallet. When a user is searching, they can send a signal to the Bluetooth finder through a mobile phone, causing the Bluetooth finder to beep or flash, providing convenience for the user. However, the distance of Bluetooth communication is affected by indoor obstacles and often cannot achieve an ideal communication distance. This makes the connection between the Bluetooth finder and the mobile phone unstable and the signal cannot be effectively transmitted to the finder. Based on the existing Bluetooth finders, people have begun to set magnetic stickers on the Bluetooth finders, so that users can use the magnetic stickers to fix the objects along with the Bluetooth finder on the indoor refrigerator body or iron rack or magnetic suction plate; they can also be placed directly in a wallet or handbag to achieve an anti-lost function.
[0003] In a Chinese patent for a Bluetooth finder with a magnetic adsorption structure (patent number: CN216700000U), the device includes a housing, a PCB circuit board and a lithium battery arranged in the housing, a bottom cover snapped into the bottom opening of the housing, and a magnetic tile arranged on the bottom cover; a pressing sheet is arranged on the outer surface of the bottom cover, and the outer peripheral edge of the pressing sheet has a plurality of convex pieces, by arranging a pressing sheet on the outer surface of the bottom cover, arranging a plurality of convex pieces on the outer peripheral edge of the pressing sheet, and bending the convex piece 90 degrees from the outer surface of the pressing sheet to the inner surface thereof to form a folded edge , fold the end of each folded edge 180 degrees toward the center of the pressing sheet and fit it to the surface of the folded edge; a card slot corresponding to the folded edge is concavely provided on the outer surface of the peripheral wall of the bottom cover opening, the magnetic tile is adsorbed on the inner surface of the pressing sheet, and the folded edge end of the pressing sheet is inserted into the corresponding card slot, so that the magnetic tile can be pressed tightly on the bottom cover to avoid the problem of the magnetic tile being easily fallen off when fixed with adhesive. However, the locator mainboard in the device is directly pressed in the shell, which has poor anti-fall protection for the locator mainboard and is easily damaged, affecting its precise positioning effect and shortening its service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Please refer to Figures 1 to 4 , in the present embodiment of the utility model, a precise positioning mechanism of a Bluetooth finder includes a positioning mechanism and a rectangular frame 1 installed on the outer sidewall of the positioning mechanism. Four symmetrically arranged installation grooves 2 are provided at the four corners of the upper sidewall of the rectangular frame 1. A spring support mechanism is provided in the installation groove 2, and the upper end of the spring support mechanism extends to the outside of the installation groove 2 and is fixedly connected to an abutting plate 3. Three equally spaced elastic abutting mechanisms are provided in each of the two sidewalls of the rectangular frame 1;
[0022] The elastic support mechanism includes a fixed cylinder 4 fixed to the inner bottom wall of the installation groove 2. A guide post 5 is fixedly connected to the inner bottom wall of the fixed cylinder 4. A sleeve 6 is sleeved and slidably connected to the upper end of the guide post 5. A first spring 7 is fixedly connected between the inner bottom wall of the fixed cylinder 4 and the lower end of the sleeve 6. The first spring 7 is sleeved outside the guide post 5. The upper end of the sleeve 6 penetrates through the upper end of the fixed cylinder 4 and is fixedly connected to the abutting plate 3. When the upper shell of the Bluetooth finder abuts tightly against the abutting plate 3, the sleeve 6 is pushed to move on the guide post 5 and retract into the fixed cylinder 4. At this time, the first spring 7 is compressed to generate elastic force. Using the elastic force of the first spring 7, the abutting plate 3 is tightly abutted against the upper shell. When the device falls, using the elastic force of the first spring 7, it can play a role in anti-fall buffering protection and extend the service life of the locator mechanism.
[0023] As Figure 1 shown: The locator mechanism includes a PCB main board 8, and the PCB main board 8 is fixed to the inner side wall of the rectangular frame 1. A Bluetooth communicator 9, a buzzer 10, and a lithium battery 11 are respectively arranged on the PCB main board 8. The Bluetooth communicator 9 is used for wireless communication with the terminal device bound to the Bluetooth finder, and when receiving a search command signal, it sends a control command to the buzzer 10 to control the buzzer 10 to sound. The lithium battery 11 is pasted on the PCB main board 8 to supply power to the Bluetooth communicator 9 and the buzzer 10. This is the prior art, so no more explanation will be given here.
[0024] As Figure 1 shown: The inner side wall of the rectangular frame 1 and the outer side wall of the PCB main board 8 are fixedly connected by adhesion, which is convenient for connection and can also be disassembled, replaced, and repaired later.
[0025] As Figure 3 shown: The elastic abutting mechanism includes an installation cavity 12 opened in the side wall of the rectangular frame 1. A moving plate 13 is slidably connected to the inner wall of the installation cavity 12. A second spring 14 is fixedly connected between the first end of the moving plate 13 and the inner wall of the installation cavity 12. A abutting block 15 is fixedly connected to the second end of the moving plate 13. One end of the abutting block 15 penetrates to the outside of the rectangular frame 1. When the rectangular frame 1 is placed in the lower shell of the Bluetooth finder, the abutting block 15 is affected by the lower shell and retracts into the installation cavity 12, which can push the moving plate 13 to squeeze the second spring 14 to generate elastic force. The elastic force of the second spring 14 rebounds to abut the abutting block 15 against the inner wall of the lower shell, playing a certain positioning effect and having an anti-fall buffering effect.
[0026] As Figure 3 shown: A limiting sliding ring 16 is fixedly connected to the outer side wall of the lower end of the sleeve 6 located in the fixed cylinder 4. The inner wall of the fixed cylinder 4 is slidably connected to the outer side wall of the limiting sliding ring 16, making the displacement of the sleeve 6 more stable.
[0027] AsFigure 1 and Figure 2 As shown in Figure 2 , rubber shock-absorbing blocks 17 are fixedly connected to the four bottom corners of the rectangular frame 1, further playing a role in anti-drop protection. Two symmetrically arranged positioning blocks 18 are fixedly connected to the two side walls at both ends of the rectangular frame 1 for easy installation and positioning. A positioning groove corresponding to the positioning block 18 is provided on the inner wall of the lower shell of the Bluetooth finder.
[0028] Working principle: When the upper shell of the Bluetooth finder is tightly abutted against the abutting plate 3, the push sleeve 6 moves on the guide post 5 and retracts into the fixed cylinder 4. At this time, the first spring 7 is compressed to generate elastic force. Using the elastic force of the first spring 7, the abutting plate 3 is tightly abutted against the upper shell. When the device falls, the elastic force of the first spring 7 can play a role in anti-drop buffering protection, prolong the service life of the locator mechanism, and the additional rubber shock-absorbing blocks 17 further play a role in anti-drop protection;
[0029] Secondly, when the rectangular frame 1 is placed in the lower shell of the Bluetooth finder, the abutting block 15 is retracted into the installation cavity 12 under the influence of the lower shell, which can push the moving plate 13 to compress the second spring 14 to generate elastic force. The elastic force of the second spring 14 rebounds to tightly abut the abutting block 15 against the inner wall of the lower shell, playing a certain positioning effect and having an anti-drop buffering effect.
[0030] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
