Description

Technical Field

[0001] This utility model relates to the technical field of headphone charging cases and protective cases, and in particular to a protective device for a magnetic wearable headphone charging case and a portable headphone charging case. Background Technology

[0002] With the widespread adoption of wireless earbuds, charging cases have become an essential accessory for everyday use. However, traditional charging cases are easily affected by external environmental factors during transport, such as bumps, scratches, and wear, which can damage the charging case or the earbuds inside. Furthermore, users typically need to place the charging case in their pockets or bags, which is inconvenient and carries the risk of forgetting or losing it. Current technology lacks a device that can effectively protect the earbud charging case while also being convenient for users to wear. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for a magnetic wearable earphone charging case and a portable earphone charging case to address the shortcomings of the existing technology. The aim is to provide physical protection for the earphone charging case and allow users to easily wear it on their clothing, thereby improving the convenience and safety of carrying it.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a protective device for a magnetic wearable earphone charging case, comprising:

[0005] Wearable items; and

[0006] The housing has a receiving space for accommodating the earphone charging case, and the housing has an adsorption surface for the wearer to be attracted.

[0007] As a further embodiment of this utility model: the shell is provided with an adsorption surface that is magnetically attracted by the wearer.

[0008] As a further embodiment of this utility model: the shell is fitted onto one side of the adsorption surface and is fitted with an adsorption element that is magnetically attracted by the wearer.

[0009] As a further embodiment of this utility model: the adsorption element is a first magnetic element, and the wearing element is a second magnetic element.

[0010] As a further embodiment of this utility model: the adsorption element is a first magnetic element, the wearing element includes a wearing shell, a wearing cover and a second magnetic element, the second magnetic element is disposed inside the wearing shell and the wearing cover is fastened to the wearing shell.

[0011] As a further embodiment of this utility model: the adsorption element and / or the wearing element are made of ferromagnetic material;

[0012] The top of the housing is provided with a top cover that matches the flip cover of the earphone charging case, and the magnetic attachment is provided on the side wall of the housing. Specifically, ferromagnetic materials such as iron, nickel, cobalt, and some iron alloys, such as steel (especially alloys containing a high proportion of iron), as well as magnetizable magnets.

[0013] As a further embodiment of this utility model: the adsorption element is a magnetic ring structure, and the shell is fitted with an annular groove embedded by the adsorption element.

[0014] As a further aspect of this invention: the adsorption element includes at least two arc-shaped magnetic strips respectively embedded in the annular groove. The annular groove is formed by winding at least two arc-shaped grooves, and the arc-shaped magnetic strips are matched and embedded in the arc-shaped grooves one by one. Specifically, through repeated research, the inventors discovered that if the adsorption element is a magnet and set as a complete annular structure, the magnetic ring will form a closed magnetic circuit, which will inevitably affect the charging effect of the protection device for the magnetic wearable earphone charging case, causing interference. Therefore, in this embodiment, the adsorption element is set as at least two arc-shaped magnetic strips, wound into a ring-like structure, and respectively embedded in the segmented annular grooves (i.e., arc-shaped grooves), so that the overall annular structure can be retained while the charging effect of the charging case will not be affected by the closed-loop magnet formed by the adsorption element.

[0015] As a further embodiment of this utility model: the side of the housing facing away from the adsorption element is provided with an indicator light hole, and the bottom of the housing is provided with a quartz hole and / or a speaker hole and / or a wired charging hole.

[0016] An opening for clearance is formed between the top cover and the shell. Specifically, since a pivot is provided between the earphone charging case and the flip cover, when the earphone charging case is flipped, wrinkles or interference may easily occur between the shell and the top cover of the protective device for the magnetic wearable earphone charging case. Therefore, the opening for clearance effectively avoids wrinkles or interference caused when the earphone charging case is flipped.

[0017] As a further embodiment of this utility model: the adsorption element has a polygonal structure, and the shell is fitted with an embedded groove that is structurally matched to the adsorption element.

[0018] This utility model also provides another technical solution: a portable earphone charging case, including a shell and a flip cover, and further including a protective device for a magnetic wearable earphone charging case as described in any one of the foregoing, wherein the shell of the portable earphone charging case is accommodated in the accommodating space.

[0019] As a further embodiment of this utility model: the top cover is fitted onto the flip cover of the portable earphone charging case.

[0020] This invention provides a protective space within the housing to accommodate the earphone charging case. Simultaneously, the housing features an adsorption surface for the wearing device, allowing the earphone charging case to be securely worn on clothing by clamping the clothing between the wearing device and the adsorption surface. Details:

[0021] 1. Provides effective protection: The case has a recessed space that completely covers the earphone charging case, preventing it from being bumped, scratched, or contaminated by dust. The case material can be selected from impact-resistant and abrasion-resistant materials, or silicone, to prevent damage caused by accidental drops, collisions, or squeezing, extending the lifespan of the charging case and further enhancing the protective effect. It is also non-toxic, baby-friendly, and provides good drop protection.

[0022] 2. Enhanced Portability: By incorporating an adhesive surface on the shell, the device can be attached to the earpiece, allowing users to wear it anywhere on their clothing, such as on the chest, cuff, or waist, freeing up their hands. This solves the problem of inconvenient carrying, eliminating the need for extra pockets or bags and making it much easier and faster to access the earphones.

[0023] 3. Reduced Risk of Loss: Since the protective device can be clipped to clothing, the earphone charging case is always within the user's sight, reducing the possibility of forgetting or losing it. The magnetic wearing design is simple and reliable, ensuring the charging case won't easily fall off during daily activities.

[0024] 4. Wide Applicability: The magnetic wearing design is flexible and suitable for various types of clothing, whether casual wear, formal wear, or sportswear. It can be easily clipped onto or removed from clothing without affecting the overall appearance, meeting user needs in different scenarios. It also frees up your hands, avoiding the inconvenience of carrying or storing it in a bag, making it particularly suitable for occasions requiring free hands, such as sports or commuting. Users don't need to frequently take the charging case out of their pockets or bags; they can simply use the earbuds on their chest or other wearing positions, improving the user experience. In scenarios requiring quick response, such as answering calls or listening to important information, it is even faster and more convenient.

[0025] 5. Simple and practical design: The protective device has a simple structure, is easy to manufacture and assemble, does not significantly increase product cost, and at the same time enhances the functionality and added value of the product.

[0026] In summary, through the above technical solutions, this invention effectively solves the problems of inconvenient carrying and easy damage of earphone charging cases in the prior art, and realizes the dual functions of protecting the charging case and making it portable, which has significant practical value and promotion prospects.

[0044] In related technologies, earphone charging cases are easily affected by external environmental factors during carrying, such as bumps, scratches, and wear, which may damage the charging case or the earphones inside. Furthermore, users typically need to put the charging case in their pockets or bags, which is inconvenient to access and carries the risk of forgetting or losing it. Current technology lacks a device that can both effectively protect the earphone charging case and be convenient for users to wear.

[0045] Therefore, embodiments of this application provide a protective device for a magnetic wearable earphone charging case and a portable earphone charging case, which can be used to provide physical protection for the earphone charging case and allow users to easily wear it on their clothing, improving portability and safety.

[0046] like Figures 1-6 As shown, this embodiment of the invention provides a protective device for a magnetic wearable earphone charging case, comprising:

[0047] Wearing part 2; and

[0048] The shell 1 has a accommodating space 1a for accommodating the earphone charging case, and the shell 1 has an adsorption surface 11 for adsorption by the wearing member 2.

[0049] This utility model provides a receiving space 1a within the housing 1 to accommodate the earphone charging case, thus providing protection. Simultaneously, the housing 1 has an adsorption surface 11 for the wearing member 2 to adhere to it. The wearing member 2 and the adsorption surface 11 adhere to each other, allowing the earphone charging case using this protective device to be securely worn on clothing; specifically, the clothing is held between the wearing member 2 and the adsorption surface 11. Details:

[0050] 1. Provides effective protection: The shell 1 has a receiving space 1a that completely covers the earphone charging case, preventing it from being bumped, scratched, or contaminated by dust from the external environment. The shell 1 of the protective device can be made of materials with impact and abrasion resistance, or silicone, to prevent damage caused by accidental drops, collisions, or squeezing, extending the service life of the charging case and further improving the protection effect. It is also non-toxic, baby-friendly, and has good drop protection.

[0051] 2. Improved Portability: By providing an adsorption surface 11 on the shell 1, which adheres to the wearing part 2, users can wear the protective device anywhere on their clothing, such as on the chest, cuff, or waist, freeing their hands. This solves the problem of inconvenient carrying, eliminating the need for extra pockets or bags, and making it more convenient and faster to access the headphones.

[0052] 3. Reduced Risk of Loss: Since the protective device can be clipped to clothing, the earphone charging case is always within the user's sight, reducing the possibility of forgetting or losing it. The magnetic wearing clip 2 design is simple and reliable, ensuring the charging case won't easily fall off during daily activities.

[0053] 4. Wide Applicability: The magnetic earpiece design is flexible and suitable for various types of clothing, including casual wear, formal wear, and sportswear. It can be easily clipped onto or removed from clothing without affecting the overall aesthetics, meeting user needs in different scenarios. It also frees up your hands, avoiding the inconvenience of carrying or storing it in a bag, making it particularly suitable for occasions requiring free hands, such as sports or commuting. Users no longer need to frequently take the charging case out of their pockets or bags; they can simply access the earphones from their chest or other wearing positions, enhancing the user experience. In scenarios requiring quick response, such as answering calls or receiving important information, it provides greater speed and convenience.

[0054] 5. Simple and practical design: The protective device has a simple structure, is easy to manufacture and assemble, does not significantly increase product cost, and at the same time enhances the functionality and added value of the product.

[0055] In summary, through the above technical solutions, this invention effectively solves the problems of inconvenient carrying and easy damage of earphone charging cases in the prior art, and realizes the dual functions of protecting the charging case and making it portable, which has significant practical value and promotion prospects.

[0056] In one embodiment, the shell 1 is provided with an adsorption surface 11 that is magnetically attracted by the wearer 2.

[0057] In another embodiment, the shell 1 is fitted with an adsorption member 12 that is magnetically attracted by the wearer 2 on one side of the adsorption surface 11.

[0058] In another embodiment, the adsorption member 12 is a first magnetic adsorption member, and the wearing member 2 is a second magnetic adsorption member 23.

[0059] In yet another embodiment, such as Figure 4 As shown, the adsorption component 12 is a first magnetic adsorption component, and the wearing component 2 includes a wearing shell 21, a wearing cover 22, and a second magnetic adsorption component 23. The second magnetic adsorption component 23 is disposed inside the wearing shell 21, and the wearing cover 22 is fastened to the wearing shell 21.

[0060] In yet another embodiment, the adsorption element 12 and / or the wearing element 2 are made of ferromagnetic material;

[0061] The top of the housing 1 is provided with a top cover 18 that matches the flip cover of the earphone charging case, and the magnetic element 12 is provided on the side wall of the housing 1. Specifically, ferromagnetic materials such as iron, nickel, cobalt, etc., as well as some iron alloys, such as steel, especially alloys containing a high proportion of iron, and magnetizable magnets.

[0062] In another embodiment, such as Figure 1 and Figure 2 As shown, the adsorption element 12 is a magnetic ring structure, and the shell 1 is provided with an annular groove 121 embedded by the adsorption element 12.

[0063] In another embodiment, such as Figure 3 and Figure 4As shown, the adsorption element 12 includes at least two arc-shaped magnetic strips 111 respectively embedded in the annular groove 121. The annular groove 121 is formed by winding at least two arc-shaped grooves 122, and the arc-shaped magnetic strips 111 are matched and embedded in the arc-shaped grooves 122 one by one. Specifically, through repeated research, the inventors found that if the adsorption element 12 is selected as a magnet and set as a complete annular structure, the magnetic ring will form a closed magnetic circuit, which will inevitably affect the charging effect of the protection device for the magnetic wearable earphone charging case and cause interference. Therefore, in this embodiment, the adsorption element 12 is set as at least two arc-shaped magnetic strips 111, wound into a ring-like structure, and respectively embedded in the segmented annular grooves 121 (i.e., arc-shaped grooves 122), so that the overall annular structure can be retained, and the charging effect of the charging case will not be affected by the adsorption element 12 forming a closed-loop magnet.

[0064] In another embodiment, such as Figure 5 As shown, the side of the housing 1 facing away from the adsorption member 12 is provided with an indicator light hole 14, and the bottom of the housing 1 is provided with a quartz hole 15 and / or a speaker hole 16 and / or a wired charging hole 17.

[0065] An opening 3 is formed between the top cover 18 and the shell 1. Specifically, since a pivot is provided between the earphone charging case and the flip cover, when the earphone charging case is flipped, wrinkles or interference may easily occur between the shell 1 and the top cover 18 of the protective device for the magnetic wearable earphone charging case. Therefore, the opening 3 effectively avoids wrinkles or interference caused when the earphone charging case is flipped.

[0066] In another embodiment, such as Figure 6 As shown, the adsorption element 12 has a polygonal structure, including but not limited to triangles, quadrilaterals, pentagons, or hexagons, etc. The shell 1 is provided with an embedded groove 123 that matches the structure of the adsorption element 12.

[0067] A portable earphone charging case includes a shell and a flip cover, and also includes a protective device for a magnetic wearable earphone charging case as described in any one of the preceding claims, wherein the shell of the portable earphone charging case is accommodated in the accommodating space 1a.

[0068] Furthermore, the top cover 18 is fitted onto the flip cover of the portable earphone charging case.

[0069] The embodiments of the protective device for the magnetic wearable earphone charging case of the present invention are as follows:

[0070] Shell 1 Structure: The shell 1 has an internal accommodating space 1a for accommodating the earphone charging case. This accommodating space 1a precisely adapts to the size of the earphone charging case, ensuring that the earphone charging case can be placed stably within it and providing a certain degree of cushioning protection. The outer surface of the shell 1 is designed as an adhesive surface, allowing the wearing piece 2 to be firmly attached to it for easy carrying. Alternatively, one side of the shell 1 is provided with an adhesive piece 12 that is magnetically attracted by the wearing piece 2. The shell 1 and / or the top cover are made of silicone material to prevent damage caused by accidental drops, collisions, or squeezing, extending the lifespan of the charging case, further improving the protective effect, while being non-toxic, baby-friendly, and providing good drop protection.

[0071] Wearing component 2 and magnetic design: Wearing component 2 is made of magnetic material or has an adsorption function, and is fixed to the adsorption surface 11 of the shell 1 by magnetic attraction. This magnetic attraction has a strong adsorption force, ensuring that the earphone charging case can be firmly fixed to the wearing component 2 and is not easy to fall off during movement. Wearing component 2 includes wearing shell 21, wearing cover 22 and second magnetic component 23. The second magnetic component 23 is located inside the wearing shell 21, and the wearing cover 22 is fastened to the wearing shell 21, which has good sealing performance.

[0072] Structure and function of the adsorption component 12: The adsorption component 12 can be configured as a magnetic ring structure, embedded in the annular groove 121 within the housing 1. The annular groove 121 is designed as an arc-shaped groove 122, which can precisely accommodate the magnetic strip in the adsorption component 12, ensuring maximum adsorption force. Simultaneously, to avoid interfering with the charging effect of the earphone charging case, such as the charging effect of earphone charging cases with wireless charging function, this invention designs at least two arc-shaped magnetic strips 111 respectively embedded in the annular groove 121, so that the adsorption component 12 can still maintain a near-ring structure, but will not form a closed-loop magnet, thereby avoiding any impact on the charging effect. Specifically, it avoids electromagnetic interference that a complete magnetic ring might cause, ensuring the normal operation of the earphone charging case's charging function. The segmented design disrupts the closure of the magnetic circuit of the magnetic ring, reducing the impact on the electronic components inside the earphone charging case.

[0073] Clearance opening 3: A clearance opening 3 is provided between the flip cover of the earphone charging case and the top cover 18 of the shell 1. This design effectively prevents wrinkles or interference caused when the earphone charging case is flipped, ensuring that the protective device can be used smoothly and that the function or ease of use of the earphone charging case is not affected by the flipping action.

[0074] Additional features: The side of the case 1 facing away from the magnetic attachment 12 has an indicator light hole 14, and the bottom has a quartz hole 15, a speaker hole 16, and / or a wired charging hole 17, enabling the earphone charging case to function as a multi-functional device. The indicator light hole 14 displays the charging status, the speaker hole 16 enhances the sound effect, and the charging hole facilitates charging.

[0075] This design utilizes a magnetic charging case protection device for wearable earphones, employing a magnetic design for convenient wearing. Users can insert the earphone charging case into the receiving space 1a of the protective case's shell 1, and then attach it to clothing using the wearing accessory 2. Specifically, the clothing is held between the wearing accessory 2 and the magnetic attachment 12 for easy carrying. When the earphone charging case needs to be removed, the magnetic attraction between the wearing accessory 2 and the shell 1 allows the charging case to easily and quickly detach from the protection device. The wearing accessory 2 provides a secure fixation via magnetic connection, preventing the charging case from falling or being damaged during use. Furthermore, the design of the shell 1 ensures that all functional openings of the earphone charging case, such as the indicator light hole 14 and the charging port, are fully exposed, allowing users to operate the charging case while wearing the protection device, improving convenience and comfort. The inclusion of a clearance opening 3 prevents interference or creases that may occur when the earphone charging case is opened, ensuring smooth opening and the stability of the protection device.

[0076] This solution provides a protective device for a magnetic wearable earphone charging case. Through the magnetic design of the shell 1 and the wearing piece 2, it offers a stable and convenient wearing solution for the earphone charging case. The internal accommodating space 1a of the shell 1 precisely matches the size of the earphone charging case, ensuring its stable placement and protection. The magnetic design allows the earphone charging case to firmly attach to the wearing piece 2, making it easy to carry and avoiding the risk of damage or loss. With its innovative recessed opening 3 and multiple functional holes, this protective device not only protects the earphone charging case but also provides greater usability, suitable for various wearing scenarios, and enhances the user experience.

Conversely, some features of the present invention are described only in a single embodiment for brevity; however, these features may also be described individually or in any suitable combination in different embodiments.
