[0002] Currently, most mainstream wireless earphones come with a portable charging case. The earphones can be placed and taken out by opening and closing the lid, and the charging and storage functions are realized at the same time. These charging cases usually adopt a small closed structure, which has a certain degree of protection and portability, and has been widely used in various scenarios such as daily commuting, sports, and office.

[0003] However, existing wireless earphone charging cases also present many inconveniences in practical use due to their enclosed box structure: 1. Users have to open the case and use their fingers to pick up the earphones every time they put them in or take them out. The operation is relatively cumbersome, especially when operating with one hand or playing games. 2. Because the earphones are completely embedded inside the case cavity with limited exposure, the feel of taking them out and putting them in is not good, and the case is prone to accumulating dust, making it difficult to clean and maintain daily. 3. Charging cases typically have a relatively flat design, which makes them less visually appealing and fails to meet users' needs for product aesthetics and desktop display. 4. Traditional slot-type fixing methods suffer from mechanical wear, which affects the lifespan of the structure. Utility Model Content

[0005] This application provides a wireless earphone charging device that is easy to pick up and put down, and the technical solution is as follows: A wireless earphone charging device that is easy to pick up and put down includes: The main body of the charging pile includes a column, a top cover, and a bottom cover. The top cover is located at the top of the column, and the bottom cover is located at the bottom of the column. The earphone receiving cavity is located on at least one side wall of the column, with the opening of the earphone receiving cavity facing the outside of the charging pile body, so that the wireless earphone is partially exposed when it is in the magnetic state.

[0009] Furthermore, this application also proposes that it includes a charging interface, which is located on the main body of the charging station and is used to connect to an external power source to provide power to the headphone charging device.

[0010] Furthermore, this application also proposes that it includes multiple charging contacts located inside the earphone housing cavity, and that the charging contacts are electrically connected to the charging interface.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Reference Figure 1 In existing technologies, wireless earphone charging cases generally adopt a closed structure, requiring users to frequently open the lid and use their fingers to remove the earphones. This operation is cumbersome and inefficient, especially in one-handed operation scenarios. The slot design of traditional charging cases results in the earphones being completely embedded inside, with limited exposed parts. This makes them prone to slipping out due to insufficient friction when being removed or placed, and repeated insertion and removal may cause mechanical wear.

[0022] To address the aforementioned issues, the applicant discovered that the existing closed structure of the charging case limits the possibility of users quickly taking out and putting away the earphones. At the same time, the slot-type fixing method cannot balance stability and convenience. Based on this, the applicant attempted to change the charging device to an open structure, allowing the earphones to be partially exposed, while adopting a non-contact fixing method to avoid plugging and unplugging. By introducing magnetic technology, the earphones can be stably fixed without being fully embedded, which simplifies the operation steps and reduces the wear and tear caused by mechanical contact.

[0023] It should be noted that the specific form of the wireless headphones mentioned in this utility model may include, but is not limited to, headphones that use Bluetooth, Wi-Fi, near field communication or other wireless protocols to achieve audio connection.

[0024] Preferably, the wireless earphone is a Bluetooth earphone, especially a TWS earphone with independent left and right channels in its structure.

[0025] Therefore, refer to Figure 2 This application proposes a technical solution including a charging pile body, an earphone receiving cavity 4 and a magnetic connection structure. The charging pile body is composed of a column 1, a top cover 2 and a bottom cover 3. The side wall of the column 1 has an earphone receiving cavity 4 with an outward opening, and the magnetic connection structure is embedded inside the receiving cavity.

[0026] The charging pile body refers to the supporting structure formed by the combination of column 1, top cover 2, and bottom cover 3. Specifically, it can adopt a cylindrical or polyhedral columnar structure, such as a triangular prism or a hexagonal prism. Its function is to provide physical support for the earphone housing 4.

[0027] The headphone receiving cavity 4 refers to the recessed space set on the side wall of the column 1, with the opening facing outward. Specifically, it can be designed as a semi-open groove. For example, the depth of the groove is 50%-70% of the headphone height. Its function is to allow the headphone to be partially exposed when placed, making it easy for the user to grab.

[0028] Magnetic connection structure refers to magnetic components embedded inside or on the surface of the receiving cavity. Specifically, permanent magnets or electromagnets can be used, such as a ring magnet array. Its function is to achieve non-contact fixation by magnetically attracting the metal contacts or built-in magnetic modules of the headphones.

[0029] In practice, when a user needs to place the earphones, they only need to bring the earphones close to the opening of the receiving cavity, and the magnetic force will automatically attract the earphones to the predetermined position. 30%-70% of the earphone shell is exposed on the outside of the cavity. The user can directly pinch the exposed part with their thumb and forefinger to take them out. During charging, the magnetic connection structure ensures that the earphones and the charging contacts 41 in the receiving cavity maintain stable contact, avoiding charging interruption due to external shaking.

[0030] Compared to existing technologies, traditional charging cases require the lid to be fully opened and precisely aligned with the slot to place the earphones. This embodiment, however, combines an open receiving cavity with magnetic fixation, enabling quick one-handed placement and reducing operational steps. In existing technologies, earphones are fully embedded in the slot, leading to reliance on friction for placement and removal. This embodiment utilizes magnetic fixation, maintaining stability even when the earphone portion is exposed, while also preventing mechanical wear on the charging port 5 caused by plugging and unplugging.

[0031] Through the above technical solution, this embodiment allows the earphones to remain partially exposed during charging, enabling users to directly observe the earphone's position and quickly pick them up or put them away without opening the case, significantly improving operational smoothness. The magnetic fixing method reduces physical contact with the earphone shell, minimizing the risk of wear and tear from long-term use, while ensuring stability during charging and preventing accidental detachment.

[0032] Further, refer to Figures 2-7 The main body of the charging pile is formed by the first end face 11, the second end face 12, the third end face 13, the top cover 2 and the bottom cover 3. The column 1 includes the first end face 11, the second end face 12 and the third end face 13.

[0033] Among them, the first end face 11, the second end face 12 and the third end face 13 refer to the three independent planes of the side wall of the column 1. Specifically, they can be formed by injection molding or metal stamping to form a closed or semi-closed geometric frame. The top cover 2 and the bottom cover 3 cover the top and bottom of the column 1 respectively. Specifically, they can be fixed by buckles or screws, and together with the three end faces, they form the outer shell structure of the charging pile body.

[0034] In practice, the three end faces, together with the top cover 2 and the bottom cover 3, form a three-dimensional frame of the column 1. The connections between the end faces are reinforced by mechanical splicing or welding. The internal space of the charging pile body is divided into multiple functional areas, such as the earphone housing 4, the circuit board mounting area, and the power interface area. The geometric distribution of the end faces provides vertical support strength to the charging pile body, while the laterally expanded functional areas can accommodate more components.

[0035] Further, refer to Figures 2-7 The first end face 11, the second end face 12 and the third end face 13 are trapezoidal, and the lower edges of the first end face 11, the second end face 12 and the third end face 13 are provided with chamfered portions 15 on both sides.

[0036] Among them, a trapezoid refers to a quadrilateral structure with a pair of parallel sides and the other two sides not being parallel. Specifically, it can be achieved by using a trapezoidal cross-section shape where the length of the upper base is shorter than that of the lower base. This shape can enhance the structural strength of the column 1 in the vertical direction.

[0037] The chamfered part 15 refers to the structure of cutting the edge corners into a plane or curved surface. Specifically, it can be achieved by forming a 30-60 degree bevel on both sides of the lower edge of the end face through machining or mold forming. This structure can eliminate sharp corners and increase the impact resistance of the edge.

[0038] Preferably, a 45-55 degree bevel is formed on both sides of the lower edge of the end face.

[0039] In specific implementation, when the first end face 11, the second end face 12, and the third end face 13 are trapezoidal, the contact area between their lower base and the bottom cover 3 increases, making the overall center of gravity distribution of the column 1 more balanced and effectively resisting the risk of tipping over. At the same time, the chamfered part 15 forms a smooth connection in the transition area between the end face and the bottom cover 3, avoiding edge collision deformation during assembly. In this embodiment, the symmetrical characteristics can be used to simplify the mold design during processing. For example, the side inclination angle of the trapezoidal end face can be uniformly set to 60 degrees, and the cutting depth of the chamfered part 15 can be controlled within 0.5 mm.

[0040] Compared to existing technologies, the rectangular end face of a traditional charging box is prone to stress concentration under load, while the trapezoidal end face disperses the load path through the inclined surface, significantly improving structural stability. In existing technologies, the sharp edges without chamfers are easily damaged by bumps during transportation or daily use. This embodiment eliminates sharp edges with the chamfered portion 15, reducing the probability of surface damage and minimizing cost increases due to excessively high precision requirements for sharp edges during manufacturing. This embodiment solves the problems of scratch risk and insufficient structural stability caused by sharp edges in charging devices, while reducing manufacturing complexity, allowing the column 1 to achieve higher impact resistance and assembly reliability while maintaining a compact appearance.

[0041] Furthermore, there are two earphone accommodating cavities 4, which are respectively located on the first end face 11 and the second end face 12.

[0042] Further, refer to Figures 2-7 It also includes a charging interface 5, which is located on the main body of the charging station and is used to connect to an external power source to provide power to the headphone charging device.

[0043] Among them, charging interface 5 refers to the physical connection structure used to connect to an external power source. Specifically, it can be implemented using a standard Type-C interface or a USB interface. Its function is to provide a continuous power input path for the charging device.

[0044] In practice, the charging interface 5 is integrated into the surface of the charging station body, such as the top cover 2 or bottom cover 3, and is connected to the internal circuitry via wires. When an external power cord is inserted into the charging interface 5, electrical energy is transferred to the charging device through the charging interface 5, and then powers the headphones through the charging contacts 41. The charging interface 5 can be positioned either concealed or exposed, for example, embedded in a slot on the side of the bottom cover 3, to avoid affecting the overall aesthetics. The charging interface 5 allows the device to operate directly from an external power source without relying on a built-in battery, reducing the frequency of repeatedly disassembling and reassembling the headphones.

[0045] Preferably, the charging interface 5 is located on the fourth end face 14 and / or the third end face 13.

[0046] Furthermore, multiple charging contacts 41 are disposed within the earphone housing cavity 4, and the charging contacts 41 are electrically connected to the charging interface 5.

[0047] Among them, the charging contact 41 refers to the conductive contact point, which can be implemented using a copper alloy sheet or a gold-plated spring pin. It is arranged in the positioning area of ​​the receiving cavity to match the position of the earphone charging electrode.

[0048] In practice, when the wireless earphone is placed into the receiving cavity, the metal charging electrode at the bottom of the earphone automatically adheres to the charging contact 41 under magnetic attraction. At this time, the external electrical energy received by the charging interface 5 is directly transferred to the earphone battery through the contact. The charging contacts 41 are symmetrically distributed on both sides of the receiving cavity, for example, using a layout of three contacts in two rows on the top and bottom, so that the earphone can achieve effective contact whether it is placed upright or on the side.

[0049] Compared to existing technologies, traditional charging cases require users to manually insert the earphones completely into the charging slot and keep them vertical in order to connect the circuit. However, this embodiment uses a combination of contact array and magnetic attraction to complete the charging circuit closure when only part of the earphones are exposed, eliminating the need for precise alignment.

[0050] Through the above technical solution, this application does not require the application of insertion and extraction force during the contact of the earphone with the charging interface 5, avoiding the problem of plating peeling caused by repeated friction of the metal terminals. At the same time, the contact array layout can be compatible with the differences in the charging electrode positions of different earphone models, reducing the probability of charging interruption caused by poor contact.

[0051] Furthermore, the bottom cover 3 is provided with multiple anti-slip parts 31.

[0052] It should be noted that the anti-slip part 31 refers to a component that changes the friction coefficient of the contact surface through physical structure. Specifically, it can be achieved by using silicone pads, rubber particles, or textured surfaces. By increasing the static friction between the bottom cover 3 and the contact surface, the displacement of the charging device caused by external forces is suppressed.

[0053] In practical implementation, when the bottom cover 3 contacts the tabletop, the anti-slip part 31 forms a local contact area with the supporting surface, generating resistance through material deformation or structural interlocking. For example, when the charging device is placed on a smooth tabletop, the silicone pad deforms due to its own elasticity, increasing the contact area and enhancing the adsorption force; when a textured surface is used, the surface grooves and the microstructure of the supporting surface interlock, forming a mechanical locking effect. Thus, the anti-slip part 31 can achieve stable fixation of the device by dispersing the direction of the force and increasing the energy dissipation path when the device is subjected to horizontal thrust or vibration.

[0054] Furthermore, the third end face 13 of the charging pile body is provided with a first fixing member, which is used to connect the charging pile body to the wall or external structural member in a detachable manner.

[0055] The first fastener refers to the component used to connect with the external support structure. Specifically, it can be achieved by using magnetic chucks, slide rail fitting grooves, or threaded locking devices, and adapting to the shape of different mounting surfaces through mechanical structure.

[0056] In practical implementation, the first fixing component is integrated into the surface or side area of ​​the third end face 13 of the charging pile body, and a magnetic module or snap-fit ​​slot can be set inside it. When wall installation is required, the charging pile body forms an adsorption or snap-fit ​​connection with the fixing seat pre-embedded in the wall through the installation interface; when desktop placement is required, the charging pile body can be directly detached from the fixing seat, and stable placement can be achieved by using the anti-slip part 31 of the bottom cover 3. This structure allows the charging device to quickly switch between the two modes, and the installation status can be adjusted without the need for additional tools.

[0057] refer to Figure 8 Furthermore, it also includes a microphone 6, which is provided with a connector 61. A fourth end face 14 is provided between the first end face 11 and the second end face 12. A second fixing member 141 is provided on the fourth end face 14. The microphone 6 is detachably connected to the second fixing member 141 through the connector 61. The microphone 6 is provided with a communication terminal 62. The fourth end face 14 of the charging pile body is provided with a communication contact 142 corresponding to the communication terminal 62. When the microphone 6 is attracted to the fourth end face 14, the communication terminal 62 and the communication contact 142 form an electrical connection to realize the electrical signal connection between the microphone 6 and the charging pile body.

[0058] The connector 61 refers to the physical fixing component set on the side of the microphone 6. Specifically, it can be implemented by means of a buckle, a magnetic adsorption block or a plug-in protrusion structure, and is combined with the second fixing component 141 through mechanical cooperation or magnetic attraction.

[0059] Preferably, the connector 61 can be the magnetic connection structure described above.

[0060] It should be noted that the second fastener 141 refers to the matching fastening structure set on the fourth end face 14, which can be implemented by groove 7, slot or magnetic adsorption piece, and is used to receive and lock the connector 61.

[0061] It should be noted that the communication terminal 62 refers to the conductive contact component located at the bottom of the microphone 6. Specifically, it can be implemented using metal contacts, spring pins, or magnetic conductive sheets, and is used to automatically establish a circuit connection after the microphone 6 is installed in place.

[0062] It should be noted that the communication contact 142 refers to the conductive contact area set on the fourth end face 14. Specifically, it can be implemented by using gold-plated contacts, elastic conductive sheets or magnetic conductive rings, forming a complementary circuit conduction path with the communication terminal 62.

[0063] Specifically, the microphone 6, through a detachable connection between the connector 61 and the second fixing member 141, can be quickly installed onto the charging pile body when needed by the user, and transmits signals through the contact between the communication terminal 62 and the communication contact 142. When the microphone 6 approaches the fourth end face 14, the connector 61 and the second fixing member 141 are fixed by magnetic attraction or mechanical snap-fit. At this time, the communication terminal 62 and the communication contact 142 form an electrical connection due to physical contact, allowing the microphone 6 to receive control signals from the charging pile body or perform charging operations. When not in use, the microphone 6 can be directly removed, avoiding the problem of dust accumulation caused by long-term fixation.

[0064] Furthermore, the microphone 6 is provided with a communication terminal 62, and the fourth end face 14 of the charging pile body is provided with a communication contact 142 corresponding to the communication terminal 62. When the microphone 6 is attracted to the fourth end face 14, the communication terminal 62 and the communication contact 142 form an electrical connection to realize the electrical signal connection between the microphone 6 and the charging pile body.

[0065] It should be noted that the communication terminal 62 refers to the conductive component disposed on the surface of the microphone 6, which can be implemented using metal contacts or gold-plated copper sheets, and is used to transmit electrical signals during physical contact. The communication contact 142 refers to the conductive component embedded in the fourth end face 14 of the charging pile, which can be implemented using elastic pins or spring pins, ensuring stable conductivity when in contact with the communication terminal 62. When the microphone 6 approaches the fourth end face 14, the magnetic connection structure generates an attractive force that brings the two together, at which point the communication terminal 62 and the communication contact 142 form a circuit path due to pressure contact.

[0066] In this embodiment, the communication terminals 62 on the microphone 6 are preferably a pair of elastic metal sheet structures, which are disposed on the side or bottom of the microphone 6; the fourth end face 14 of the charging pile is provided with communication contacts 142 corresponding to the communication terminals 62 one by one. The communication contacts 142 are gold-plated spring pin structures, which are installed on a flexible circuit board or printed circuit board and electrically connected to the internal communication module of the charging pile.

[0067] In specific implementation, the communication module adopts a serial audio interface based on the I²C protocol (TI's TLV320ADC3101 chip can be used, but is not limited to) or a general UART communication module. The TLV320ADC3101 chip is connected to the communication contact 142, reads the audio signal voltage from the microphone 6, and converts it into digital audio data. The audio data can be further uploaded to an external mobile terminal through the built-in Bluetooth module (Nordic nRF52840 chip can be used, but is not limited to) to realize the remote transmission of the audio input signal of the microphone 6.

[0068] The microphone 6 can be an electret microphone module with digital output (such as Knowles SPH0645LM4H, but not limited to this), and its signal line is transmitted to the communication contact 142 through the communication terminal 62 and is recognized by the audio acquisition chip built into the charging pile. This module features low power consumption, automatic wake-up, and compatibility with Bluetooth audio standards, and can be directly embedded in the headphone charging device.

[0069] Optionally, the microphone 6 is also provided with an audio interface for establishing a physical connection with other audio input devices.

[0070] Preferably, the audio interface is a standard 3.5mm plug structure, used to detachably connect the microphone 6 to external headphones or electronic terminals with audio input functions. Through the audio interface, the microphone 6 can be used with this charging device or as an independent audio module adapted to other devices, achieving universal compatibility across multiple devices.

[0071] Optionally, the outer surface of the column 1 of the charging pile body is provided with several grooves 7 to reduce the overall weight, enhance the three-dimensional appearance, and improve handheld comfort.

[0072] Specifically, the groove 7 is arranged along the vertical direction of the column 1, preferably at the edge position between two adjacent end faces, or it can be arranged in the center or edge area of ​​each end face.

[0073] The cross-section of the groove 7 can be semi-circular, V-shaped, rectangular, triangular or trapezoidal, and is integrally formed during the injection molding of the shell. The depth of the groove 7 is preferably 2-5mm, so as to achieve weight reduction without weakening the structural strength.

[0074] Preferably, the inner wall of the groove 7 can be provided with a light guide strip, a decorative strip, or used to hide the screw channel, and can also be used for subsequent integration of modules such as lights and microphone 6 for recognizing status indicators.

[0075] In this embodiment, the charging pile body is also equipped with a speaker assembly 8, so that this embodiment can be used as an external speaker even when the headphones are not connected. The speaker assembly 8 includes a power amplifier circuit, a speaker unit, an audio signal processing chip, and corresponding power supply lines, all of which are integrated into the internal structure of the column 1.

[0076] Specifically, the speaker unit is preferably installed on the top cover 2, bottom cover 3, or third end face 13 of the charging pile body, and is used to achieve sound propagation by opening a sound outlet or setting an acoustically permeable diaphragm structure. The audio signal processing module can use a common Bluetooth audio decoding chip (such as the JL AC692x series, BES2300 series, or CSR8645 series, but not limited to these), and is connected to the power supply module and control circuit board. The Bluetooth chip can establish a wireless audio connection with an external mobile terminal to realize the decoding and playback of wireless audio input.
