Description

Technical Field

[0001] The present invention relates to the technical field of earphone charging compartments, and in particular to a charging detection device and method for earphone batteries. Background Art

[0002] The wireless Bluetooth headset is a pair (two). Since it is wireless, it is easy to wear and use. After using the wireless Bluetooth headset for a period of time, in order to extend its battery life, it needs to be placed in the matching charging compartment to complete charging. The traditional charging compartment is small in size and easy to carry. It consists of a rotating cover and a compartment body. The compartment body is equipped with a charging head and a charging port is opened at the bottom of the compartment. When charging, open the rotating cover, place the two headsets in the charging compartment, and plug the matching USB cable into the charging port to complete the charging work. After charging is completed, open the rotating cover and take the headset out of the charging compartment.

[0003] However, this charging compartment cannot detect heat, nor can it automatically power off the earphones to protect them when the charging heat is too high. It also cannot quickly release or cool down the heat in the charging compartment when the earphones are charging and the power is cut off, resulting in a shorter service life of the charging compartment. Therefore, how to improve the service life of the charging compartment and how to improve heat dissipation efficiency are the problems that need to be solved now. Summary of the invention

[0004] In order to solve the above problems and increase the service life of the charging compartment, the present invention provides a charging device and method for an earphone battery.

[0006] As a further preferred embodiment, the earphone sockets are both provided in the second earphone socket and the first earphone socket, and when the second earphone socket is rotated onto the first earphone socket, the earphone sockets therebetween overlap correspondingly up and down, so as to confine the two earphones in the upper and lower earphone sockets respectively.

[0007] As a further preferred embodiment, a partition compartment is provided in the inner cavity of the charging compartment, the charging head is inserted into the partition compartment from the top end, and the expansion agent is located at the periphery of the partition compartment.

[0008] As a further preferred embodiment, the trigger rod is a composite pipe, the bottom end of the trigger rod is a metal tube, the top end of the trigger rod is an expansion tube, the bottom end of the metal tube is connected to the lifting plate and can be lifted and lowered along with the lifting plate, the earphone socket is provided with a jack communicating with each other up and down, and when the expansion tube rises with the metal tube, it detaches from the jack upward into the earphone socket and produces an expansion effect in the earphone socket.

[0009] As a further preferred embodiment, a plurality of air holes are provided on the metal tube and the expansion tube along the circumferential direction, the bottom end of the metal tube passes downward to the bottom surface of the lifting plate into the charging cabin, and is connected to the lifting plate, the bottom end of the metal tube is closed, and the top end of the expansion tube is closed, and when the expansion tube is detached from the earphone socket and produces an expansion effect in the earphone socket, the air holes on the expansion tube are opened.

[0010] As a further preference, a USB charging terminal is provided at the bottom end of the charging head, and the USB charging terminal corresponds to the top of the charging hole.

[0011] As a further preferred embodiment, a protrusion is provided on the side of the charging head, and the protrusion is located above the lifting plate. When the lifting plate hits the protrusion during its rising stroke, the protrusion is used to push the charging head to rise, and the charging head drives the USB charging terminal to rise.

[0012] The present invention also provides a detection method for a charging device for earphone batteries, which is applicable to the charging device for earphone batteries as described above, and comprises the following steps:

[0013] A temperature sensor is arranged inside the charging compartment; an alarm is arranged outside the charging compartment. When high temperature occurs, the high temperature heat is transferred to the temperature sensor, and the temperature sensor instructs the alarm to send an alarm signal, and the charging relationship between the charging line and the USB charging terminal is cut off according to the alarm signal;

[0014] The high temperature heat is consistent with the expansion coefficient of the expansion agent. The high temperature alarm is also when the expansion agent expands. When this high temperature occurs, not only does the expansion agent begin to expand, but the alarm also sounds.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. During the charging process, the charging head generates high heat due to internal faults of the headset, circuit faults in the charging head, or faults in the USB charging terminal and the charging cable. When the heat temperature reaches the expansion coefficient of the expansion agent, the expansion agent will expand. As the temperature rises rapidly, the expansion capacity of the expansion agent increases. The higher expansion capacity acts on the lifting plate and pushes the lifting plate up. The lifting plate pushes the trigger rod up. When the top of the trigger rod enters the earphone socket, the earphone is pushed upward from the earphone socket, and the earphone pushes the second earphone seat, which pushes the rotating cover to open the rotating cover. At this time, the earphone leaves the earphone socket and is away from the high-temperature environment, thereby increasing the service life of the earphone. Since the rotating cover will also be automatically pushed open, the high heat will also be released from the top of the charging compartment to avoid explosion, greatly increasing the service life of the charging device.

[0017] 2. When the lifting plate rises and hits the protrusion, the protrusion is used to push the charging head to continue to rise, and the charging head drives the USB charging terminal to rise. Once the USB charging terminal rises, it is equivalent to separating the USB charging terminal from the charging line, and charging stops. The reason for the rise of the lifting plate is that the heat generated by the charging head reaches the expansion coefficient of the expansion agent. At this time, the lifting plate is also the time when the trigger rod removes the earphones from the charging device. Therefore, when high temperature occurs, not only the earphones and the charging device are cooled and protected, but also when high temperature occurs, the entire charging device can be cut off from the external power supply, and the protection means are more complete.

DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown:

[0028] This embodiment provides a charging device for earphone batteries, including a charging compartment 1, a rotating cover 2 hinged (the hinged connection mentioned here can also be understood as an active connection, such as a buckle connection, etc.) at the top of the charging compartment 1, a first earphone seat 3 arranged in the charging compartment 1, a second earphone seat 4 arranged in the rotating cover 2, and a trigger mechanism 5 arranged in the charging compartment 1;

[0029] The trigger mechanism 5 includes an expansion agent 6 filled in the charging chamber 1, and also includes a lifting plate 7 that slides up and down in the charging chamber 1;

[0030] The bottom of the first earphone seat 3 is provided with a charging head 8, and the bottom end of the charging compartment 1 is provided with a charging hole 9, and the bottom end of the charging head 8 is connected to the charging hole 9. The charging principle of the charging head 8 and how to form a charging relationship with the external charging line are the charging technologies currently possessed by various charging components. This technology is very mature, such as the charging principle of mobile phones, etc. The prior art will not be repeated. The bottom end of the charging head 8 passes through the lifting plate 7 downward and approaches the bottom of the charging compartment 1; the bottom end of the charging head 8 is provided with a USB charging terminal 14, and the USB charging terminal 14 corresponds to the top of the charging hole 9;

[0031] The trigger mechanism 5 also includes two trigger rods 11 fixed on the top surface of the lifting plate 7, and the two trigger rods 11 are symmetrical on both sides of the charging head 8. Two earphone sockets 12 are opened on the first earphone seat 3, and the two earphone sockets 12 are respectively located above the two trigger rods 11. The top ends of the two trigger rods 11 penetrate upward into the two earphone sockets 12. When the lifting plate 7 rises, the two trigger rods 11 are pushed to rise, so that the top ends of the two trigger rods 11 rise along the two earphone sockets 12, and the second earphone seat 4 is pushed by the top end, so that the rotating cover 2 leaves the top end of the charging compartment 1 and deflects upward.

[0032] Both the second headphone seat 4 and the first headphone seat 3 are provided with headphone sockets 12. When the second headphone seat 4 is rotated onto the first headphone seat 3, the headphone sockets 12 therebetween overlap correspondingly up and down to confine the two earphones in the upper and lower headphone sockets 12, respectively. It can be seen that when the rotating cover 2 is covered on the charging compartment 1, the earphones can be covered on the charging compartment 1, and the earphones are in a storage state during the charging process, which is more reasonable.

[0033] When in use, place the two earphones in the two earphone sockets 12 of the first earphone holder 3, insert the charging ends of the two earphones into the top of the charging head 8, rotate the rotating cover 2 downward and cover it on the charging chamber 1 to fix the earphones in the earphone sockets 12, insert the USB head of the charging cable into the USB charging terminal 14 through the charging hole 9, provide power to the charging head 8 through the USB charging terminal 14, and provide power to the first earphone holder 3 from the charging head 8. The power is used to charge the two earphones through the two earphone sockets 12. During the charging process, the charging head 8 generates high heat due to internal faults of the earphones, circuit faults in the charging head 8, or faults in the USB charging terminal 14 and the charging cable. When the heat temperature reaches the expansion coefficient of the expansion agent 6, the expansion agent 6 will expand rapidly, and this temperature surge will cause the expansion agent 6 to expand rapidly. When the temperature rises rapidly, the expansion capacity of the expansion agent 6 will increase rapidly, and the higher expansion capacity will act on the lifting plate 7, and push the lifting plate 7 to rise rapidly, and the lifting plate 7 will push the trigger rod 11 to rise rapidly, so that the top of the trigger rod 11 will quickly enter the earphone socket 12. Since the earphone is located in the earphone socket 12 when charging, when the top of the trigger rod 11 quickly enters the earphone socket 12, the top will be used to push the earphone upward from the earphone socket 12. Since the rotating cover 2 covers the top of the earphone during charging, when the earphone is pushed upward, the earphone will also use the second earphone seat 4 to provide thrust to the rotating cover 2, that is, the second earphone seat 4 pushes the rotating cover 2 to open the rotating cover 2. At this time, the earphone is pushed away from the earphone socket 12 by the same push, so that it is away from the high-temperature environment, thereby improving the service life of the earphone. At the same time, since the rotating cover 2 will be automatically pushed open, the higher heat will also be released upward from the top of the charging compartment 1, so that the top of the charging compartment 1 is opened, so that the heat is quickly released, and explosion is avoided, which greatly improves the service life of the charging device.

[0034] like Figures 4 to 6 As shown, the trigger rod 11 is a composite pipe, the bottom end of the trigger rod 11 is a metal tube 15, the top end of the trigger rod 11 is an expansion tube 16, the bottom end of the metal tube 15 is connected to the lifting plate 7, and can be lifted and lowered along with the lifting plate 7, and a socket 17 communicating with each other from top to bottom is provided on the earphone socket 12, when the expansion tube 16 rises with the metal tube 15, it detaches from the socket 17 upward into the earphone socket 12, and produces an expansion effect in the earphone socket 12. When the trigger rod 11 is pushed up by the lifting plate 7, the metal tube 15 on the bottom section of the trigger rod 11 is pushed up first, and the metal tube 15 pushes the expansion tube 16 on the top section to rise, and forces the expansion tube 16 to be pushed into the earphone socket 12 from the jack 17 of the first earphone socket 3. The expansion tube 16 is not only pushed into the earphone socket 12, but also expands upward in the earphone socket 12, and provides an instantaneous thrust to the earphone while expanding, so that the earphone can be more effectively separated from the earphone socket 12, and the thrust when the earphone is separated from the earphone socket 12 can be used to more effectively open the rotating cover 2. In addition, a plurality of air holes 18 are provided on the metal tube 15 and the expansion tube 16 along the circumferential direction. The bottom end of the metal tube 15 passes downward to the bottom surface of the lifting plate 7 and enters the charging cabin 1, and is connected to the lifting plate 7. The bottom end of the metal tube 15 is closed, and the top end of the expansion tube 16 is closed. When the expansion tube 16 is detached from the earphone socket 12 and produces an expansion effect in the earphone socket 12, the air holes 18 on the expansion tube 16 are opened. In addition to utilizing the upward movement of the trigger rod 11 to detach the earphone from the earphone socket 12, the air holes 18 at the bottom are also utilized to deliver hot air into the trigger rod 11, and then the hot air is discharged through the air holes 18 at the top along the tube cavity of the trigger rod 11 to the outside of the air charging device.

[0035] In another embodiment, if Figures 5 to 7 As shown, a protrusion 19 is provided on the side of the charging head 8, and the protrusion 19 is located above the lifting plate 7. When the lifting plate 7 rises and hits the protrusion 19, the protrusion 19 is used to push the charging head 8 to rise, and the charging head 8 drives the USB charging terminal 14 to rise. Once the USB charging terminal 14 rises, it is equivalent to separating the USB charging terminal 14 from the charging line, and charging stops. The reason for the rise of the lifting plate 7 is that the heat generated by the charging head 8 reaches the expansion coefficient of the expansion agent 6. At this time, the lifting plate 7 takes the trigger rod 11 to remove the earphone from the charging device. Not only the earphone and the charging device are cooled and protected, but also when high temperature occurs, the entire charging device can be cut off from the external power supply, and the protection means are more perfect.

[0036] like Figure 4As shown, a partition 13 is provided in the inner cavity of the charging compartment 1, the charging head 8 and the USB charging terminal 14 connected to the bottom of the charging head 8 are inserted into the partition 13, and the expansion agent 6 is located outside the partition 13. When the expansion agent 6 is originally filled in the charging compartment 1, it will not adhere to the charging head 8 and the USB charging terminal 14 due to the isolation of the partition 13. At the same time, when the power is cut off, it can also ensure that the charging head 8 and the USB charging terminal 14 can rise smoothly.

[0037] The present invention provides a detection method for a charging device for an earphone battery, which is applicable to the charging device for an earphone battery as described above, and comprises the following steps:

[0038] A temperature sensor is provided inside the charging compartment 1; an alarm 20 is provided outside the charging compartment 1. When high temperature occurs, the high temperature heat is transferred to the temperature sensor, and the temperature sensor instructs the alarm 20 to send an alarm signal, and the charging relationship between the charging line and the USB charging terminal 14 is cut off according to the alarm signal;

[0039] The high temperature heat is consistent with the expansion coefficient of the expansion agent 6, and the high temperature alarm is also when the expansion agent 6 expands. When this high temperature occurs, not only the expansion agent 6 begins to expand, but also the alarm 20 alarms. The alarm 20 mentioned here can be a light alarm signal emitted by a diode, or a sound alarm signal emitted by a buzzer, etc.

[0040] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0041] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
