[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" (if any) should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of an earphone battery quick-release device provided by an embodiment of the present invention, the earphone battery quick-release device comprises: a battery module, a quick-release module and a hanging power module, the battery module comprises a battery body and a battery compartment 12, the quick-release module comprises a quick-release guide rail and a battery compartment 12 cap, The above-mentioned power-hanging module includes a golden hand guide plate 4 and a spring clip seat 9, wherein: the above-mentioned battery body is arranged in the battery compartment 12, and is connected to the above-mentioned quick-release guide rail through the guide rail groove 7 on the outer wall of the battery compartment 12; the above-mentioned battery compartment 12 cap is arranged at one end of the battery compartment 12, and the above-mentioned battery compartment 12 is opened through the opening groove 10 arranged on the battery compartment 12 cap; the above-mentioned golden hand guide plate 4 is arranged at the other end of the battery compartment 12, and is connected to the spring clip seat 9 after the battery compartment 12 cap is closed.

[0023] Specifically, the above-mentioned battery module may include but is not limited to a battery body and a battery compartment 12. The above-mentioned battery compartment 12 is used to place batteries. The battery can be any type of battery pack on the market for powering wireless headphones, such as button batteries, matrix batteries, etc. It can be understood that the size of these batteries can match the above-mentioned battery compartment 12 and can freely enter the interior of the battery compartment 12.

[0024] The outer wall of the battery compartment 12 also has a guide groove 7, which is used to limit the position of the battery compartment 12 entering the earphone body. Generally speaking, when the battery compartment 12 enters the earphone body, it is necessary to calibrate the position through the guide groove 7 so that the gold hand guide plate 4 set on the battery compartment 12 can be electrically connected with the corresponding spring holder 9 after entering the battery body.

[0025] The battery compartment 12 cap can be opened through the opening groove 10. It can be understood that, through the reserved opening groove 10, the battery compartment 12 cap can be opened by prying or other operations with a lever principle.

[0026] It can also be explained that a gripping portion 6 for taking out the battery compartment 12 is provided at the end of the battery compartment 12 away from the golden hand guide piece 4. It can be understood that the gripping portion 6 can pull the battery compartment 12 out of the earphone body horizontally; a raised limiting portion 5 for limiting the quick-release guide rail is also provided at the end of the battery compartment 12 close to the golden hand guide piece 4. The limiting portion is located on one side of the guide rail groove 7 and is slightly higher than the guide rail groove 7, and is used to limit the position of the battery compartment 12 when it is pushed into the interior of the earphone body.

[0027] A sliding limiter 1 is provided inside the quick-release guide rail for limiting and fixing with the battery compartment 12 cover cap; a sliding limiter groove 11 for connecting the sliding limiter 1 is also provided on the battery compartment 12 cover cap; the sliding limiter groove 11 can be connected to the sliding limiter 1 on the quick-release guide rail by horizontal lateral sliding.

[0028] Specifically, the sliding limit member 1 can be a cylindrical component, and the sliding limit member 1 is inserted into the sliding limit groove 11 to ensure that when the sliding limit groove 11 slides horizontally to the distance limit, the sliding limit member 1 can be used to prevent the movement of the sliding limit groove 11, thereby ensuring that the battery compartment 12 cap connected to the sliding limit groove 11 will not fall off.

[0029] A connecting slide groove 3 is also provided inside the quick-release guide rail, which is used to connect and limit the guide groove 7 on the outer wall of the battery compartment 12. Specifically, the connecting slide groove 3 can be a component that wraps around the outer wall of the battery compartment 12 and has a track that can be embedded in the guide groove 7 on the outer wall of the battery compartment 12. The component can be composed of a soft material on the outer shell, while the internal slide rail is composed of a hard material. It can be understood that by embedding and assembling the guide groove 7 on the outer wall of the battery compartment 12 with the connecting slide groove 3 inside the quick-release guide rail, the battery compartment 12 can be positioned by the guide rail therebetween, so that after the battery compartment 12 enters the earphone body, the gold hand guide plate 4 and the spring holder 9 can accurately calibrate the position for electrical connection.

[0030] The connecting slide groove 3 is provided with a conical fixing portion 2 for limiting the battery compartment 12; a sliding stopper 1 for connecting the cap of the battery compartment 12 is provided between the conical fixing portions 2. Specifically, the conical fixing portions 2 can be symmetrically arranged on both sides of the sliding stopper 1 and have the same length as the connecting slide groove 3, so as to meet the requirements of docking the battery compartment 12. Generally speaking, the acute angle portions of the conical fixing portions 2 on both sides are oriented in the opposite direction to the position of the sliding stopper 1, so as to be able to be connected to the guide rail groove 7 of the battery compartment 12 through the acute angle portions.

[0031] A power-hanging part 8 is also provided on one side of the battery compartment 12 close to the gold hand guide sheet 4; the power-hanging part 8 is a connection structure that is concave toward one side of the gold hand guide sheet 4, and is used for the spring clip seat 9 to be embedded in the power-hanging part 8 and connected with the gold hand guide sheet 4. Specifically, when the spring clip seat 9 is embedded in the power-hanging part 8, since the spring clip seat 9 is made of elastic material, it will produce elastic deformation when it contacts the gold hand guide sheet 4, and since the spring clip seat 9 is in an arched shape, when it is embedded in the power-hanging part 8, the concave structure of the power-hanging part 8 can be used to perform effective elastic pressure division to ensure the effective connection between the gold hand guide sheet 4 and the spring clip seat 9.

[0032] In the embodiments of the present invention, a battery module, a quick-release module and a hanging power module, the battery module includes a battery body and a battery compartment 12, the quick-release module includes a quick-release guide rail and a battery compartment 12 cap, the hanging power module includes a golden hand guide plate 4 and a spring clip seat 9, wherein: the battery body is arranged in the battery compartment 12, and is connected to the quick-release guide rail through the guide rail groove 7 on the outer wall of the battery compartment 12; the battery compartment 12 cap is arranged at one end of the battery compartment 12, and the battery compartment 12 is opened by an opening groove 10 arranged on the battery compartment 12 cap; the golden hand guide plate 4 is arranged at the other end of the battery compartment 12, and is connected to the spring clip seat 9 after the battery compartment 12 cap is closed, which solves the problems of inconvenient battery replacement, poor stability, and easy falling off and loss of traditional wireless headsets.

[0033] like Figure 2 As shown, Figure 2 A method for charging a headset quick-release device is provided in an embodiment of the present invention, and the method comprises: 201. Detect the voltage between the golden hand guide sheet and the spring sheet seat, and determine the voltage difference between the golden hand guide sheet and the spring sheet seat.

[0034] In an embodiment of the present invention, the power-on method of the above-mentioned earphone quick-release device can be used in the above-mentioned earphone battery quick-release device, and the above-mentioned earphone battery quick-release device can carry an intelligent detection module for detecting and controlling various data when the earphone battery is connected.

[0035] The voltage between the above-mentioned golden hand guide plate and the above-mentioned shrapnel seat can be detected by the above-mentioned intelligent detection module, and specifically can be detected based on the current flow and contact impedance change between the golden hand guide plate and the shrapnel seat. For example, through a current sensor (such as a Hall sensor or a current sensing resistor), the intelligent detection module monitors the current value between the golden hand guide plate and the shrapnel seat in real time, and then calculates the corresponding voltage through Ohm's law.

[0036] The change of the above-mentioned contact impedance will change with the change of factors such as contact pressure and temperature. Specifically, it will change with the change of usage time and the influence of the external environment (such as temperature change, contact surface contamination, etc.). Therefore, in order to improve the accuracy of voltage detection, the above-mentioned intelligent detection module will use a contact impedance sensor (such as a sensor for measuring resistance changes) to monitor the impedance changes between the contact surfaces in real time, and use it as a compensation parameter to improve the accuracy of voltage estimation.

[0037] 202. Based on the voltage difference, control the gold hand guide plate to be electrically connected to the spring holder.

[0038] The above control process can be determined by comparing the voltage difference obtained above with the preset voltage threshold. Specifically, the above preset voltage threshold can be set according to the low voltage and the high voltage. For example, when the voltage difference is lower than a certain set value, it means that the contact between the gold finger guide plate and the spring plate seat may be loose or poor, and the electrical connection may be disconnected. When the voltage difference is higher than a certain set value, it may be due to poor contact, resulting in excessive current, excessive voltage, and even damage. Therefore, a preset voltage threshold interval can be determined according to the minimum voltage and the maximum voltage.

[0039] In a possible embodiment, after analyzing the above-mentioned voltage difference, when the voltage difference is too low, it may indicate that the contact pressure is insufficient, resulting in poor contact. Therefore, the intelligent detection module can dynamically adjust the contact pressure between the gold finger guide plate and the spring plate seat through an external driving device (such as a servo motor or a piezoelectric element) to ensure stable electrical contact.

[0040] Optionally, in the step of detecting the voltage between the golden hand guide plate and the spring clip seat and determining the voltage difference between the golden hand guide plate and the spring clip seat, it also includes determining the pressure value between the golden hand guide plate and the spring clip seat; by comparing the pressure value with a preset pressure threshold, adjusting the distance between the golden hand guide plate and the spring clip seat so that the pressure value is restored to the preset pressure range.

[0041] In an embodiment of the present invention, since the stability of the above-mentioned voltage difference depends not only on the voltage difference but also on the contact pressure, a pressure sensor (such as a piezoelectric sensor or a resistive pressure sensor) can be arranged on the contact surface of the gold finger guide plate or the spring seat to detect the pressure change on the contact surface and provide real-time pressure data. Finally, the corresponding voltage difference stability is analyzed based on the pressure data to ensure stable output after power-on.

[0042] The preset pressure threshold interval can be used by the intelligent detection module to compare the pressure value detected in real time to determine whether it is within the preset pressure interval. When the current pressure value is lower than the lowest pressure threshold, the contact between the gold hand guide sheet and the spring sheet seat may not be tight enough, which may result in unstable electrical connection. When the current pressure value is higher than the highest pressure threshold, the pressure is too high, which may cause the contact surface between the gold hand guide sheet and the spring sheet seat to wear, resulting in unstable electrical connection.

[0043] In a possible embodiment, the intelligent detection module fine-tunes the distance between the gold finger guide piece and the spring holder according to the corresponding pressure value and a preset pressure threshold range through a small motor or a piezoelectric expansion material.

[0044] Optionally, in the step of detecting the voltage between the golden hand guide plate and the spring clip seat and determining the voltage difference between the golden hand guide plate and the spring clip seat, it includes detecting the instantaneous current value between the golden hand guide plate and the spring clip seat; and determining the voltage difference between the golden hand guide plate and the spring clip seat based on the instantaneous current value.

[0045] In an embodiment of the present invention, the instantaneous current value between the golden hand guide plate and the spring clip seat can be detected by the intelligent detection module. Specifically, through a current sensor (such as a Hall sensor or a current sensing resistor), the intelligent detection module monitors the instantaneous current value between the golden hand guide plate and the spring clip seat in real time through a preset time interval, and then calculates the corresponding instantaneous voltage difference through Ohm's law.

[0046] The preset time interval may be determined according to the time when the pressure value exceeds the preset pressure threshold interval. Generally speaking, when the pressure value exceeds the preset pressure threshold interval, the instantaneous current value will be detected continuously.

[0047] Optionally, in the step of determining the voltage difference between the golden hand guide plate and the spring clip seat based on the instantaneous current value, it includes determining the current working state between the golden hand guide plate and the spring clip seat based on the instantaneous current value; based on the working state, controlling the golden hand guide plate and the spring clip seat to perform power-on operation.

[0048] In an embodiment of the present invention, the instantaneous current value between the golden hand guide plate and the shrapnel seat is detected by the above-mentioned intelligent detection module, and the current instantaneous current value is analyzed and judged according to the power consumption rate of the earphone. When it is confirmed that the power consumption rate of the earphone does not match the current instantaneous current value, it means that the contact between the above-mentioned golden hand guide plate and the shrapnel seat is poor, resulting in a mismatch in voltage, current, and power consumption rate. Therefore, the power supply can be automatically disconnected or the corresponding reminder information can be sent to the APP by adjusting the corresponding contact distance.

[0049] The above method can accurately determine the working status between the gold hand guide plate and the spring holder through real-time current monitoring, and take intelligent control measures according to different status to ensure stable electrical connection and avoid equipment damage caused by poor contact or overload, thereby improving the reliability and safety of the equipment. At the same time, it can also automatically remind users to handle abnormal conditions, thereby improving user experience.

[0050] Those skilled in the art can understand that the implementation of all or part of the processes in the above-mentioned embodiments can be completed by instructing the relevant hardware through a computer program, and can be stored in a computer-readable storage medium. When the program is executed, it can include the processes of the embodiments of the above-mentioned methods. The storage medium can be a disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM).

[0051] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
