[0002] The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1 megabyte per second and a maximum transmission distance of 10 meters. By increasing the transmission power, it can reach 100 meters. A Bluetooth headset applies Bluetooth technology to hands-free headsets, allowing users to get rid of the annoyance of wires and freely make calls in various ways. Since the advent of Bluetooth headsets, they have always been a good tool for mobile business people to improve efficiency.

[0003] Currently, wireless headsets that transmit signals using Bluetooth technology are popular among users due to their characteristics such as being free from wire constraints and convenient for storage. To improve the battery life of wireless headsets, wireless headsets are usually equipped with a headset charging case.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] As Figures 1 - 3 shown, an embodiment of the present invention discloses a Bluetooth headset charging device applied to a headset charging case. The headset charging case includes a case body 10 and a charging base 11, and the charging base 11 is detachably plugged into the case body 10; two headset slots 12 for placing Bluetooth headsets are provided on the upper surface of the charging base 11.

[0026] The charging device includes a first charging mechanism and a second charging mechanism that can respectively charge the Bluetooth headset. Both the first charging mechanism and the second charging mechanism are provided in the case body 10 and are located below the charging base 11.

[0027] The first charging mechanism and the second charging mechanism are switched by a switching module and then separately charge the Bluetooth headset; the first charging mechanism includes a charging battery, and the charging battery is electrically connected to the charging circuit of the Bluetooth headset;

[0028] The switching module includes a detection module and a control module. The signal input end of the detection module is electrically connected to the charging battery, the signal output end of the detection module is electrically connected to the signal input end of the control module, and the signal output end of the control module is electrically connected to the second charging mechanism. The detection module is used to detect the power of the charging battery, and the signal output end of the control module is electrically connected to the micro motor 50.

[0029] It should be noted that the detection module for detecting the battery power in the embodiment of the present invention samples existing detection devices. And the control module in this embodiment samples an existing PLC controller.

[0030] In the embodiment of the present invention, by setting the switching module, it can be realized that when the detection module detects that the power of the charging battery is zero and then sends a signal to the control module, the control module controls the second charging mechanism to start, and then charges the Bluetooth headset through the second charging mechanism. Then, when the power of the charging battery is used up, in the scenario where the Bluetooth headset user is outdoors or other scenarios where the charging box cannot be charged through the mains power supply, the second charging mechanism as a backup power supply can be used to charge the charging box, and then the Bluetooth headset can be charged.

[0031] When the Bluetooth headset user uses the Bluetooth headset outdoors and the power of the charging battery is used up

[0032] The second charging mechanism includes a vibration support base 2 and a vibration charging component 3. The vibration charging component 3 is arranged on the vibration support base 2 and generates current through the vibration of the vibration support base 2 to charge the Bluetooth headset;

[0033] In the embodiment of the present invention, vibration is generated to convert the vibration energy into electrical energy and use it as a backup power supply to charge the Bluetooth headset. At the same time, a vibration support base is set to buffer the vibration impact energy, and it can also buffer the vibration impact force generated when the box body vibrates during vibration power generation, which can play a buffering role, reduce the vibration of the box body itself, and keep the box body stable.

[0034] In this embodiment, the vibration generating mechanism includes a support plate 40, a vibration ball 41, a vibration plate 42 and a vibration assembly. The support plate 40 is fixed to the top of the fixed ring 23. The vibration ball 41 is fixedly connected to the lower side of the vibration plate 42. The vibration plate 42 drives the vibration ball 41 to contact the support plate 40 through the vibration assembly, thereby generating vibration. The vibration assembly includes a micro motor 50 and a sliding sleeve 51. The power output shaft of the micro motor 50 is connected to the drive shaft 52 through a coupling. The end of the drive shaft 52 is fixedly connected with a cam 53. A sliding rod 54 is slidably connected to the sliding sleeve 51. The bottom of the sliding rod 54 is fixedly connected with a force receiving block 55. A sleeve spring 58 is sleeved on the sliding rod 54. The top of the sliding rod 54 is of an arc structure, and the top of the sliding rod 54 contacts the bottom of the vibration plate 42. One side of the vibration plate 42 is rotatably connected to the inner side wall of the box body 10. A connecting spring 56 is fixedly connected to the top of one side of the vibration plate 42. The top of the connecting spring 56 is fixedly connected with a connecting block 57. One end of the connecting block 57 is fixedly connected to the inner side wall of the box body 10.

[0035] In the embodiment of the present invention, through the above settings, it can be realized that by starting the micro motor, the power output shaft of the micro motor rotates to drive the drive shaft to rotate, and the drive shaft rotates to drive the cam to rotate. Therefore, the cam squeezes the force receiving block at different radii, and then the top of the sliding rod can squeeze the vibration plate. And under the elastic force of the connecting spring, the vibration plate vibrates up and down. The vibration plate vibrating up and down drives the vibration ball to vibrate up and down. The vibration ball vibrating up and down impacts the support plate, causing the support plate to vibrate.

[0036] In this embodiment, the vibration support base 2 includes a base 20, a sliding support rod 21, a fixed block 22, a fixed ring 23 and an elastic member 24. A vertical sliding groove is provided on the base 20. The sliding support rod 21 is slidably fitted on the base 20. The fixed block 22 is arranged on the sliding support rod 21. The fixed ring 23 is fixed to the lower end face of the vibration generating mechanism, and the outside of the fixed ring 23 is connected to the sliding support rod 21. The elastic member 24 is sleeved on the sliding support rod 21, and the elastic member 24 is located between the fixed block 22 and the base 20.

[0037] It should be noted that the elastic member in this embodiment can be a spring or an elastic structure such as a spring sheet. It can buffer the vibration impact generated when the box body vibrates during vibration power generation, play a buffering role, and reduce the vibration of the box body itself.

[0038] In this embodiment, the vibration charging assembly 3 includes a permanent magnet 30 and a coil 31. The permanent magnet 30 is fixed on both sides of the base 20, and the magnetic field generated by the permanent magnet 30 covers the positions where the elastic member 24 and the fixed block 22 are located. The upper part of the inner side of the coil 31 is fixed to the fixed block 22.

[0039] In the embodiment of the present invention, through the above settings, when the support plate is impacted by the vibration ball and generates vibration, the support plate transfers the generated energy to the fixed block in the vibration reduction support seat. The fixed block vibrates up and down, thereby causing the coil fixed on the fixed block to move up and down. As a result, the coil cuts the magnetic induction lines generated by the permanent magnets on both sides, and thus an electric current is generated in the coil. The coil in this embodiment can be electrically connected to the charging circuit of the Bluetooth headset through a wire. Therefore, the electric current generated in the coil provides power for the charging circuit of the Bluetooth headset through the wire, thereby realizing the charging of the Bluetooth headset.

[0040] In the embodiment of the present invention, the energy generated by vibration is converted into electrical energy to provide power for charging the Bluetooth headset. In the embodiment of the present invention, the Bluetooth headset is charged by vibration power generation, improving the utilization rate of energy.

[0041] In this embodiment, an installation cavity 6 is fixedly arranged on the outer wall of one side of the box body 10, and the micro motor 50 is fixedly arranged in the installation cavity 6.

[0042] Through the above settings in this embodiment, the fixed installation of the micro motor is realized.

[0043] Finally, it should be noted that only the specific embodiments of the present invention are described in detail above. However, the present invention is not limited to the above-described specific embodiments. Equivalent modifications and substitutions made by those skilled in the art to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention are covered by the present invention.
