Description

Technical Field

[0001] This invention relates to the field of charging box system technology, specifically a Bluetooth microphone charging box system. Background Technology

[0002] Nowadays, due to the rise of the self-media industry, lavalier Bluetooth microphones are widely used. They typically consist of a small microphone and a clip, which can be easily attached to a collar or neckline for recording or playback. They can capture the user's voice or singing and output a clear audio signal. Lavalier microphones can generally be used by plugging into devices such as mobile phones, recording equipment, or amplifiers, and are characterized by their small size, light weight, and portability.

[0003] Charging a lavalier Bluetooth microphone is also very convenient. When charging is needed, simply place the microphone into the matching charging case. The charging case then connects to a power source to provide continuous power to the microphone. Generally, a Bluetooth microphone can be fully charged in 1-2 hours. However, overheating can easily occur during charging. Therefore, the charging case should be disconnected from the power source as soon as the microphone is fully charged to avoid damaging the battery due to prolonged overcharging. However, the power disconnection process is usually manually controlled, making it difficult to disconnect the power in a timely manner. Over time, this will affect the microphone's performance and lifespan, reducing the user's sense of security. Summary of the Invention

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 12 The present invention provides a technical solution: a Bluetooth microphone charging case system, comprising:

[0041] The detection module is used to detect the charging status of the microphone; when the detection module detects that the microphone is fully charged, it transmits the signal to the timing module.

[0042] The timing module records the duration of the microphone's charging time when it is fully charged. When the time recorded by the timing module exceeds ten minutes, it will send a power-off command to the automatic power-off module, which will then force the power-off module to shut off the power.

[0043] The power on / off module is used to start or stop charging; the power on / off module is directly connected to the power supply of the charging box.

[0044] Manual power-off module: The manual power-off module is used to manually control the power-off module to disconnect power.

[0045] Automatic power-off module, used to automatically control the power-off module to disconnect power;

[0046] The automatic temperature control module is used to regulate the ambient temperature during charging. The module adaptively opens or closes the through-hole 6 according to the microphone's charging status, and works in conjunction with the cooling fan 7 to regulate the internal temperature of the housing 1.

[0047] Furthermore, this Bluetooth microphone charging case system, equipped with multiple management modules, can automatically power off when fully charged, thereby avoiding overcharging, reducing energy waste, extending battery life, and providing users with a more convenient user experience.

[0048] like Figures 1-3 As shown, the charging box system is set inside the box body 1. The box body 1 has a lid 2 at the top and a power inlet 3 at the top right side wall. The upper half of the front side of the box body 1 has a power switch module, which includes a power button 4, a stand block 8 and a moving contact 11. One end of the moving contact 11 is connected to the stationary contact, and the other end of the moving contact 11 is fixedly connected to the stand block 8. The stand block 8 is slidably installed inside the box body 1. Both the manual power-off module and the automatic power-off module can independently control the outward pop-out action of the stand block 8. The power button 4 extends from the front end of the box body 1 and is fixedly connected to the stand block 8.

[0049] The box 1 has a microphone placement cavity 101 and a hollow cavity 103 arranged sequentially from top to bottom. The bottom of the placement cavity 101 has a through hole 102. Both sides of the hollow cavity have multiple linearly distributed through holes 6. The automatic temperature control module includes a cooling fan 7, a door-shaped outer frame 35 and an inner ventilation pipe 36. The cooling fan 7 is located in the hollow cavity 103. Each set of through holes 6 has a set of inner ventilation pipes 36 that communicate with the hollow cavity. The inner ventilation pipes 36 are fitted with a door-shaped outer frame 35. The door-shaped outer frame 35 is driven by a pushing mechanism to perform horizontal telescopic movement. A third guide plate 39 is also rotatably installed on the door-shaped outer frame 35.

[0050] Specifically, the cover 2 is rotated and installed on the box body 1. In the actual charging process, the microphone is first placed in the mounting cavity 101, the cover 2 is closed, and then the charging cable is inserted into the power port 3 so that the stationary contact in the box body 1 is connected to the power. Then the power button 4 is pushed so that the moving contact makes contact with the energized stationary contact, thereby starting to charge the microphone in the mounting cavity 101.

[0051] like Figure 5 , Figure 7As shown, a spring 10 is fixedly connected to the end of the upright block 8 away from the power button 4. The spring 10 is sleeved on the moving contact 11. A lateral bite 801 is provided on the left side of the upright block 8. A locking block 12 is inserted into the lateral bite 801. One end of the locking block 12 is set in an arc shape. A rectangular moving block 13 is fixedly connected to the other end of the locking block 12. The rectangular moving block 13 is slidably installed in the box body 1. An S-shaped spring piece 14 is fixedly connected to the side of the rectangular moving block 13 away from the locking block 12.

[0052] Furthermore, by setting a first spring 10, the power button 4 can be quickly pushed outward after the locking block 12 moves out of the lateral bite 801, so that the moving contact 11 breaks contact with the stationary contact, achieving the effect of quick power-off; and by setting the locking block 12, the rectangular moving block 13 and the S-shaped spring 14 to work together, the upright block 8 can be quickly limited and fixed without the interference of external forces, so that the moving contact 11 and the stationary contact are in stable contact, maintaining the effect of continuous charging.

[0053] like Figure 7 As shown, the rectangular moving block 13 has a first inclined groove and a second inclined groove arranged sequentially on its front and rear sides. The first inclined groove is connected to the manual power-off module, and the second inclined groove is connected to the automatic power-off module. The manual power-off module includes an auxiliary button 5, an auxiliary push rod 17, a second spring 18, and a limiting block 19. The limiting block 19 is slidably installed in the housing 1. One end of the auxiliary push rod 17 is fixedly connected to the limiting block 19, and the other end of the auxiliary push rod 17 is inserted into the first inclined groove. A set of second springs 18 is arranged on both the upper and lower sides of the auxiliary push rod 17. The second springs 18 are fixedly connected to the limiting block 19. The auxiliary button 5 extends into the housing 1 and is fixedly connected to the limiting block 19. The automatic power-off module includes an L-shaped push rod 15 and a miniature electric push rod 16. The miniature electric push rod 16 is fixedly installed in the housing 1. One end of the L-shaped push rod 15 is fixedly connected to the piston rod of the miniature electric push rod 16, and the other end of the L-shaped push rod 15 extends into the second inclined groove.

[0054] Furthermore, by providing a first inclined groove and a second inclined groove on both sides of the rectangular moving block 13, the present invention enables the manual power-off module and the automatic power-off module to control the extension and retraction of the card block 12 independently without interfering with each other, both of which can achieve the power-off effect. The design of the manual power-off module and the automatic power-off module can provide two power-off methods: electric control and manual control. This avoids overcharging and allows users to freely control the charging time, achieving the convenient effect of charging and using as needed.

[0055] like Figures 10-11As shown, a first guide plate 37 and a second guide plate 38 are arranged sequentially from the inside to the outside of the inner ventilation pipe 36. The first guide plate 37 and the second guide plate 38 are arranged obliquely on the inner wall of the inner ventilation pipe 36. A central shaft 40 is fixedly inserted into the upper end of the third guide plate 39. The two ends of the central shaft 40 extend into the door frame 35 and are fixedly connected to the driven wheel 41. A push rack 42 is meshed with the upper end of the driven wheel 41. The push rack 42 is slidably installed in the door frame 35 and a No. 4 spring 43 is fixedly connected to the end of the push rack 42 away from the driven wheel 41.

[0056] Furthermore, when the outer frame 35 of the door extends outward, the driven wheel 41, the push rack 42, and the fourth spring 43 work together to cause the central shaft 40 to drive the third guide plate 39 to deflect downward by 30°, forming a wave-shaped gas channel with the second guide plate 38 and the third guide plate 37. By setting the first guide plate 37, the second guide plate 38, and the third guide plate 37 to work together, the inlet and outlet through holes 6 can be separated and blocked, thereby changing the shape of the airflow inlet and outlet channel. This not only facilitates the discharge of hot air inside the box 1 through the through holes 6 to the outside, but also reduces the probability of external dust entering the through holes 6 to a certain extent, thereby achieving the effect of low dust and temperature control.

[0057] like Figures 10-11 As shown, pads 3502 are fixedly connected to both sides of the lower end face of the door-shaped outer frame 35. The pads 3502 are flush with the lower end of the box body 1. Sloping grooves 3501 are opened on both the left and right sides of the door-shaped outer frame 35. A toggle pin 34 is inserted into the sloping groove 3501. The toggle pin 34 is fixedly connected to a driven support rod 33. The driven support rod 33 is slidably installed in the box body and connected to the pushing mechanism.

[0058] Furthermore, by setting the pad 3502, the bottom support of the gate-shaped outer frame 35 can be provided. While the gate-shaped outer frame 35 extends outward, it can open the through hole 6 to allow heat to be dissipated from the inside of the box 1. On the other hand, it can also increase the bottom force-bearing area of ​​the box 1, further stabilizing the placement of the box 1, thereby providing the microphone with a highly stable charging environment.

[0059] like Figure 5 , Figure 6 as well as Figure 8As shown, the pushing mechanism includes a driven bar 9, a wedge-shaped moving block 20, a driven rack 22, a rotating shaft 24, a lead screw 28, an X-shaped hinge rod 30, and a main push rod 32. The upper end of the driven support rod 33 is fixedly connected to the main push rod 32. The main push rod 32 is slidably installed in the housing 1. A groove is opened on the upper end face of the main push rod 32, and a slider 31 is slidably installed in the groove. The lower end of the X-shaped hinge rod 30 is rotatably connected to the slider 31. The upper end of the X-shaped hinge rod 30 is rotatably connected to the lead screw nut 29. The lead screw nut 29 is sleeved on the lead screw 28. The lead screw 28 is coaxially welded from two short screws with opposite thread directions, and the end of the lead screw 28 near the power button 4 is coaxially fixedly connected to the second pulley 27. The wedge-shaped moving block 20 is slidably installed inside the box 1. One end of the wedge-shaped moving block 20 is fixedly connected to the No. 3 spring 21, and the other end of the wedge-shaped moving block 20 is connected to the driven bar 9. The driven bar 9 is fixedly connected to the upright block 8. One end of the driven rack 22 is fixedly connected to the wedge-shaped moving block 20. The lower end of the driven rack 22 is meshed with a spur gear 23. A rotating shaft 24 is fixedly inserted inside the spur gear 23. The rotating shaft 24 is coaxially fixedly connected to the No. 1 pulley 25. A transmission belt 26 is sleeved on the outside of the No. 1 pulley 25 and the No. 2 pulley 27.

[0060] Furthermore, by using a wedge-shaped moving block 20, a third spring 21, a driven rack 22, a spur gear 23, a rotating shaft 24, a first pulley 25, a transmission belt 26, and a second pulley 27 in combination, the linear pushing force of the driven bar 9 in the X-axis direction can be converted into the rotational motion of the lead screw 28. By using an X-shaped hinge rod 30, a slider 31, a main push rod 32, a driven support rod 33, and a lever pin 34 in combination with the inclined groove 3501, the rotational motion of the lead screw 28 can be converted into the synchronous horizontal telescopic movement of multiple portal frames 35.

[0061] In use, when charging is required, first place the microphone in the mounting cavity 101, close the cover 2, then insert the charging cable into the power port 3, so that the stationary contact inside the housing 1 is connected to the power source. Then push the power button 4, so that the moving contact contacts the energized stationary contact, thereby starting to charge the microphone in the mounting cavity 101. During this process, the stand block 8 also moves inward under the push of the power button 4, so that the driven bar 9 is pressed against the inclined surface of the wedge-shaped moving block 20, so that the wedge-shaped moving block 20 is forced to compress the third spring 21 and drive the driven rack 22 to move in the opposite direction to the driven bar 9. The driven rack 22 acts on the spur gear 23, so that the rotating shaft 24 drives the first pulley 25 to rotate clockwise. The first pulley 25 acts on the second pulley 27 through the transmission belt 26, so that the transmission belt 26 drives the second pulley 27 to rotate clockwise. The second pulley 27 drives the lead screw 28 to rotate. Since the lead screw 28 is made of two sets of short lead screws welded together on the same axis, the two sets of lead screw nuts 29 move in opposite directions, causing the X-shaped hinge rod 30 to deform and push the main push rod 32 downward. The main push rod 32 acts on the driven support rod 33, and the actuating pin 34 on the driven support rod 33 acts on the inclined groove 3501, causing the gate-shaped outer frame 35 to be stretched outward. At the same time, as the third guide plate 39 gradually moves away from the inner ventilation pipe 36, the push rack 42 extends outward under the elastic force of the fourth spring 43 and acts on the driven wheel 41, causing the central shaft 40 to drive the third guide plate 39 to flip downward, thus forming a wave-shaped gas channel with the second guide plate 38 and the third guide plate 37, and cooperating with the cooling fan 7 to facilitate the discharge of heat generated during the charging process of the box 1.

[0062] When the detection module detects that the microphone is fully charged, it immediately transmits the signal to the timing module. When the time recorded by the timing module exceeds ten minutes, it transmits a power-off command to the automatic power-off module. The automatic power-off module receives the signal and activates the miniature electric push rod 16, causing the piston rod of the miniature electric push rod 16 to perform a rapid piston movement. This causes the L-shaped push rod 15 to quickly extend into the second inclined groove and then quickly retract. During this process, the rectangular moving block 13 is forced to pull the locking block 12 out of the side bite 801, thereby releasing the limiting effect on the upright block 8. Under the elastic force of the first spring 10, the upright block 8 drives the moving contact 11 to move towards the power button 4, thereby achieving the purpose of forcibly cutting off the power. As the power-off ends, the internal temperature of the box 1 drops. The automatic temperature control module receives the signal and controls the cooling fan 7 to turn off, while the door-shaped outer frame 35 retracts inward and the third guide plate 39 flips upward to block and seal the through hole 6, ensuring the sealing performance of the box 1.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
