Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth modules, in particular to a waterproof structure of a Bluetooth module. Background Art

[0002] A Bluetooth module is a PCBA board with integrated Bluetooth function, which is used for short-range wireless communication. It is generally composed of a Bluetooth chip integrated on a PCB board, an onboard antenna, a wiring port, and a shielding cover connected to the outside of the Bluetooth chip. When using a Bluetooth module, a waterproof structure of the Bluetooth module is required.

[0003] In the prior art, when waterproofing the Bluetooth module, a waterproof cover is generally used. However, in the prior art, when fixing and installing the waterproof cover to the circuit board, it is generally done by welding or gluing. Although these two methods can effectively fix the waterproof cover to the circuit board, the fixing process is relatively time-consuming and labor-intensive, which increases the workload of the staff. In addition, after the glue is used for a long time, it is inevitable that the glue will come off, which will affect the fixing effect of the waterproof cover, so that the waterproof cover cannot effectively waterproof the Bluetooth module. Moreover, when the waterproof cover in the prior art is used for wiring the Bluetooth module, it is generally achieved by a sealing film. After the sealing film is used for a long time, it is inevitable that it will become weak and aged, which will cause the overall sealing performance of the waterproof cover to be reduced, thereby affecting the waterproof effect of the waterproof cover.

[0004] In contrast to the Chinese patent with publication number CN219555404U, the utility model relates to the technical field of Bluetooth modules, and in particular to a waterproof structure of a Bluetooth module, comprising a waterproof cover, the bottom of the waterproof cover is fixedly connected to a bottom frame, the bottom inner side of the bottom of the bottom frame is embedded with a waterproof ring, the bottom of the bottom frame and the outer side of the waterproof ring are integrated with an adhesive area, one side of the top of the waterproof cover is integrated with a circular ring, the inside of the circular ring is fixedly connected with a sealing film, the surface center of the sealing film is provided with a broken groove, the bottom frame can be adhered and fixed to the product circuit board through the adhesive area, the product circuit board is integrated with a Bluetooth module, and the Bluetooth module is wrapped in the waterproof cover. The utility model solves the problem that the Bluetooth chip, on-board antenna and other electronic components on the PCB board of the existing Bluetooth module are all exposed and fixed, and do not have a waterproof function. If it is used in an environment with humidity or heavy water vapor, it will be affected by the external environment, resulting in a short circuit in the internal circuit, thereby affecting the life of the product.

[0005] The above scheme can very conveniently provide waterproof protection for the Bluetooth module, but the above scheme still uses the adhesive area to fix the waterproof cover and the circuit board, and the above scheme still uses a sealing film to seal the waterproof cover, which fails to solve the problems raised in the above background technology.

[0006] Therefore, those skilled in the art provide a waterproof structure of a Bluetooth module to solve the problems raised in the above background technology. Utility Model Content

[0031] See also Figure 1 - Figure 7 As shown, this embodiment provides a waterproof structure of a Bluetooth module, including a circuit board 1, and also including:

[0032] The module body 7 is arranged on the upper surface of the circuit board 1;

[0033] A positioning frame 2 is fixedly connected to the upper surface of the circuit board 1, and a waterproof cover 3 is provided inside the positioning frame 2;

[0034] The connecting plates 4 are respectively arranged on both sides of the outer wall of the waterproof cover 3, and the bottoms of the two connecting plates 4 are fixedly connected to the connecting frames 5;

[0035] The fixing frames 6 are symmetrically arranged on the upper surface of the circuit board 1, and the upper surfaces of the two fixing frames 6 are provided with guide grooves for the connection frames 5 to move;

[0036] The fixing components are respectively arranged inside the two connection frames 5 and are used to fix the connection frame 5 and the fixing frame 6, so that the waterproof cover 3 can be installed;

[0037] The sealing assembly is arranged on the upper surface of the waterproof cover 3 and is used to seal the waterproof cover 3 , and can also facilitate the user to perform wiring processing on the module body 7 .

[0038] The above working principle: when the module body 7 needs to be waterproofed, it is only necessary to first plug the waterproof cover 3 into the interior of the positioning frame 2. At this time, the waterproof cover 3 will drive the connecting plate 4 to move synchronously, and the connecting plate 4 will drive the connecting frame 5 to be synchronously plugged into the guide groove on the upper surface of the fixed frame 6. When the connecting frame 5 is fully inserted into the interior of the fixed frame 6, the connecting frame 5 and the fixed frame 6 are fixed by the fixing component. At this time, the waterproof cover 3 and the circuit board 1 can be conveniently and effectively fixed and installed, so that the waterproof cover 3 can effectively perform waterproof protection on the module body 7. Through the setting of the sealing component, the waterproof cover 3 can be effectively sealed, and at the same time, it can be convenient for the staff to perform wiring on the module body 7, effectively improving the overall waterproof performance of the waterproof cover 3, saving time and effort.

[0039] In order to conveniently and effectively fix and install the waterproof cover 3 and the circuit board 1, the fixing components include fixing blocks 11 respectively arranged inside the two connecting frames 5, the front end surfaces and the rear end surfaces of the two fixing blocks 11 are fixedly connected with telescopic rods 12, the telescopic ends of the multiple telescopic rods 12 are fixedly connected with plug-in rods 13, the outsides of the multiple telescopic rods 12 are sleeved with return springs 14, and the multiple return springs 14 are in contact between the plug-in rods 13 and the fixing blocks 11, and the front end surfaces and the rear end surfaces of the two connecting frames 5 and the fixing frame 6 are provided with guide grooves for the plug-in rods 13 to move.

When the plug rod 13 is plugged into the guide grooves on the front and rear surfaces of the fixed frame 6, the connecting frame 5 and the fixed frame 6 can be fixed. At this time, the waterproof cover 3 and the circuit board 1 can be fixedly installed, so that the waterproof cover 3 can effectively perform waterproof protection on the module body 7. In addition, this structure does not require the staff to use glue and welding, etc., to fix the waterproof cover 3 to the circuit board 1, which effectively improves the installation efficiency of the waterproof cover 3.

[0040] Taking into account that after the connecting frame 5 and the fixing frame 6 are fixed, it is necessary to further improve the fixing effect between the connecting frame 5 and the fixing frame 6, so as to further improve the installation effect between the waterproof cover 3 and the circuit board 1, the upper surfaces of the two fixing frames 6 are symmetrically provided with positioning sleeves 9, and the bottoms of the two fixing blocks 11 are provided with guide grooves for the positioning sleeves 9 to move. When the fixing between the connecting frame 5 and the fixing frame 6 is completed, the positioning sleeve 9 will also be synchronously inserted into the guide groove at the bottom of the fixing block 11.

The other end of the bundle is led out through the guide groove opened on the upper surface of the waterproof cover 3. At this time, the module body 7 can be wired. During the movement of the closing disk 20, the outer plate 19 will also be driven to move synchronously. The outer plate 19 will then drive the rotating sleeve 18 to rotate synchronously. The rotating sleeve 18 will then stretch the volute spring 17 synchronously. When there is no need to wire the module body 7, just loosen the connecting belt 10. At this time, the volute spring 17 is reset, driving the rotating sleeve 18 to rotate synchronously. The rotating sleeve 18 will then drive the outer plate 19 and the closing disk 20 to move synchronously. The closing disk 20 will then drive the sealing gasket 21 to move synchronously.

In addition, the size of the guide groove opened on the upper surface of the waterproof cover 3 is set according to the diameter of the wiring harness.

[0043] In addition, in order to effectively extend the service life of the waterproof cover 3 , the material of the waterproof cover 3 is rubber. The rubber material has good wear resistance and flexibility, so the waterproof cover 3 also has the same properties, thereby effectively extending the service life of the waterproof cover 3 .
