DETAILED DESCRIPTION

[0030] The utility model is now described in further detail with reference to the accompanying drawings.

[0031] See also Figures 1 to 9 The utility model provides a technical solution: a Bluetooth module that is easy to disassemble and assemble, comprising a Bluetooth module body 1, a PCB board 2, a plug 3, a heat sink 15 and a rotating seat 13. The lower end of the Bluetooth module body 1 is provided with a PCB board 2, and positioning holes 4 for the plugs 3 to penetrate are all opened at the four corners of the upper end of the PCB board 2. A plurality of plugs 3 are movably connected in a cavity opened at the upper end of the heat sink 15. A strip groove 5 for a flat screwdriver to plug is opened at the top of the plug 3. A reset spring 6 is abutted between the plug 3 and the cavity. Two arc plates 7 are fixedly installed on the outer side of the lower end of the plug 3. The upper end of the Bluetooth module body 1 is respectively provided with terminals 8 for connecting with other electronic devices and an interface for installing a Bluetooth antenna 9;

[0032] The middle part of the cavity is fixedly installed with a ring member 10 for limiting the arc plate 7 at the lower end of the latch pin 3, and grooves 11 matching the outer contour of the arc plate 7 are provided on both sides of the middle part of the ring member 10;

[0033] The middle of the bottom end of the heat sink 15 is penetrated with an embedding groove for installing the heat sink fin 12. The upper end of the heat sink fin 12 contacts the lower end of the PCB board 2. The lower end of the heat sink fin 12 penetrates to the bottom of the heat sink 15 and is located at the gap between the heat sink 15 and the rotating seat 13. The rotating seat 13 is rotatably connected to the outside of the heat sink 15 through the rotating shaft 14. Considering that the installation method of the Bluetooth module on the market can be divided into horizontal patch or vertical direct insertion, the traditional fixing method is welding fixation. The existing method also uses adhesive to bond it inside the electronic device housing. When it needs to be disassembled for maintenance, it is more troublesome. It is necessary to use a hot air gun to melt the adhesive and then remove it. The utility model adopts the method of fixing the Bluetooth module body 1 with the pin 3 and the heat sink 15, which is not only convenient for early installation, but also simple to operate when maintenance and disassembly are needed in the later stage. It is only necessary to use a flat-blade screwdriver to insert the strip groove 5 on the top of the pin 3 and press it down, so that the pin 3 is compressed by the reset spring piece 6, and then the flat-blade screw is turned to make the arc plate 7 at the bottom of the pin 3 pass through the groove 11 in the middle of the ring part 10, and then the flat-blade screw is turned again to make the arc plate 7 and the groove 11 misaligned so as to conflict with the bottom of the ring part 10. At this time, the Bluetooth module body 1 can be directly It can be directly pulled out for maintenance, which is convenient. Compared with the existing method of fixing with glue, there is no need to use a hot air gun to melt the adhesive glue for a long time. Compared with the method of fixing with screws, the convenience of disassembly and installation is improved without screwing. Compared with the method of fixing with welding, the convenience is significantly improved, and there is no need to remove the wires and then use a welding gun for welding. During installation, the rotating seat 13 is first fixed to the motherboard inside the electronic device by screws, and then the rotating shaft 14 is used to make the heat sink 15 vertical, and then the Bluetooth module body 1 is taken out and inserted into the middle of the heat sink 15, and the heat sink fins 12 in the middle of the heat sink 15 are aligned with the Bluetooth After the PCB board 2 of the module is in contact, a flat-blade screwdriver is used to penetrate the positioning holes 4 in sequence and plug the strip groove 5 on the top of the plug 3. The arc block that abuts against the bottom of the ring 10 is rotated by rotation. When the arc block passes through the groove 11 of the ring 10, the plug 3 will be reset and ejected by the reset spring 6, thereby penetrating the positioning hole 4. At this time, the heat sink 15 and the Bluetooth module body 1 will be fixed. Thereafter, the heat sink 15 will be flattened, and then the limit plate 17 will be moved so that the limit plate 17 moves to the upper end of the heat sink 15 and contacts its surface, thereby completing the limit. Then, the Bluetooth module body 1 and the electronic device will be connected using a wire.

[0034] Among them, sliding grooves for the sliding of T-shaped rods 16 are opened on the upper ends of both sides of the heat sink 15, the front ends of the two T-shaped rods 16 are fixed to the back of the same limiting plate 17, and the bottom of the limiting plate 17 is in conflict with the upper end of the heat sink 15. The length of the heat sink 15 is smaller than the length of both sides of the rotating seat 13. Considering that when the device is installed inside other electronic equipment and connected to its circuit board, the Bluetooth module body 1 cannot be horizontally inserted into the heat sink 15 due to the obstruction of parts on the circuit board. At this time, the limiting plate 17 will be disengaged from the conflict with the upper end of the heat sink 15 by sliding the T-shaped rod 16, and finally the heat sink 15 will be directly rotated to make the heat sink 15 vertical, and then the Bluetooth module body 1 will be inserted into the middle of the heat sink 15 and fixed with the pin 3.

[0035] Among them, the lower side of the inner wall of each positioning hole 4 is designed to be corrugated, and the corrugated end 18 is used to abut against an elastic ring 19. The elastic ring 19 is sleeved on the outer middle end of the pin 3. A plurality of spherical protrusions 20 that abut against the corrugated end 18 of the positioning hole 4 are provided on the outer wall surface of the elastic ring 19. Considering the degree of fastening between the pin 3 and the positioning hole 4, the elastic ring 19 is sleeved on the outside of the pin 3. When the pin 3 is pushed into the inside of the positioning hole 4, the spherical protrusions 20 on the outside of the elastic ring 19 abut against the inside of the plurality of corrugated ends 18 inside the positioning hole 4 and are staggered with them, thereby improving the stability between the pin 3 and the positioning hole 4.

[0036] Among them, auxiliary heat dissipation copper wires 21 are connected and penetrated between multiple fin-shaped ends at the upper ends of the heat dissipation fins 12, and the outer surface of the auxiliary heat dissipation copper wires 21 is in conflict with the fin-shaped ends of the heat dissipation fins 12, and the two ends of the multiple auxiliary heat dissipation copper wires 21 are respectively penetrated into multiple heat dissipation cavities 22 opened on both sides of the heat dissipation seat 15. By setting the heat dissipation fins 12, the temperature generated when the Bluetooth module body 1 is working is played a role in heat transfer and heat dissipation, and in order to improve the heat dissipation effect, multiple auxiliary heat dissipation copper wires 21 are interspersed between the multiple fin-shaped ends of the heat dissipation fins 12, so that part of the heat generated when the Bluetooth module body 1 is working is discharged through the lower end of the heat dissipation fins 12, and the other part is discharged to the two sides of the heat dissipation seat 15 through the auxiliary heat dissipation copper wires 21, thereby performing multi-directional heat dissipation.
