Description

Technical Field

[0001] This application belongs to the field of headphone technology, and more specifically, relates to a Bluetooth headphone charging case and a Bluetooth headphone assembly. Background Technology

[0002] With the widespread adoption of wireless technology, Bluetooth earphones have become an indispensable electronic product in modern life. To provide power and storage for Bluetooth earphones, various charging cases have emerged on the market. Existing Bluetooth earphone charging cases are typically fully or partially enclosed box-like structures, requiring the earphones to be completely placed inside for charging. During charging, the charging case's logic circuitry ensures that the earphones are completely disconnected from mobile phones and other electronic devices, preventing signal interference during charging.

[0003] For some exquisitely designed Bluetooth earbuds with decorative appeal, traditional fully enclosed charging cases completely cover the earbuds during charging, failing to meet users' desire to showcase their personalized earbuds. Existing semi-enclosed charging cases lack an effective securing mechanism when charging, making them prone to displacement due to slight movement or wear during use, leading to loosening or separation of the charging contacts. Once the contacts separate, charging immediately interrupts, and the earbuds automatically attempt to reconnect to the user's electronic device, causing a reconnection that not only affects charging efficiency but also provides a poor charging experience. Utility Model Content

[0004] The purpose of this application is to provide a Bluetooth earphone charging case and Bluetooth earphone assembly to solve the technical problems in the prior art where the personalized design of the earphone cannot be displayed when the Bluetooth earphone is fully wrapped for charging, and the connection is prone to loosening when the earphone is partially wrapped for charging.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a Bluetooth earphone charging case, comprising:

[0006] The charging case body has two earphone slots, each used to accommodate a Bluetooth earphone. The earphone slots have an open structure, so that at least part of the outer surface of the Bluetooth earphone placed therein is exposed.

[0007] A limiting member is provided on the charging case body, which can apply force to the Bluetooth earphone placed in the earphone slot to stably fix the Bluetooth earphone in the earphone slot.

[0008] Optionally, an arched structure is provided between two adjacent earphone slots, and the limiting member is fixed on the arched structure to apply at least a lateral force to the Bluetooth earphone placed in the earphone slot, wherein the direction of the lateral force is perpendicular to the plane of symmetry between the two earphone slots.

[0009] Optionally, the arched structure is provided with a hanging hole, and a wearing device is inserted into the hanging hole.

[0010] Optionally, the arched structure is provided with mounting holes, the limiting member is fitted into the mounting holes, and the hanging rope hole communicates with the mounting holes.

[0011] Optionally, the wearing component is a chain, lanyard, or buckle, used to wear the charging case body on the user or hang it on an object.

[0012] Optionally, the limiting member is spherical or ellipsoidal in shape; and / or, the limiting member has a pushing surface extending into the earphone slots on both sides, the pushing surface being used to abut against a Bluetooth earphone placed in the earphone slots.

[0013] Optionally, the limiting member is an elastic member.

[0014] Optionally, the elastic element is a silicone element, a rubber element, or a thermoplastic elastic element.

[0015] Optionally, the Bluetooth earphone charging case further includes a magnetic component, which is fixed to the charging case body so that it can attract the magnet on the Bluetooth earphone when the Bluetooth earphone is charging.

[0016] This application also provides a Bluetooth headset component, including a Bluetooth headset and a Bluetooth headset charging case as described above, wherein the Bluetooth headset is pluggable and detachable and charged in the headset slot.

[0017] The advantages of the Bluetooth earphone charging case and Bluetooth earphone provided in this application are as follows: Compared with the prior art, the charging case body of this application has an open earphone slot, which can be displayed when the Bluetooth earphone is inserted into the earphone slot. In addition, the limiting member set on the charging case body can provide force to the Bluetooth earphone, so that the Bluetooth earphone is stably fixed in the earphone slot under the dual action of the earphone slot wall and the limiting member, which prevents the Bluetooth earphone from reconnecting to the electronic device due to loosening, thus improving the user's charging experience.

[0033] Please see Figures 1 to 3 This application provides a Bluetooth headset charging case, which includes a charging case body 10 and a limiting member 20. For example... Figure 4 As shown, the charging case body 10 has two earphone slots 11, each used to accommodate a Bluetooth earphone 200. The earphone slots 11 have an open structure, ensuring that at least a portion of the outer surface of the Bluetooth earphone 200 is exposed. A limiting member 20 is provided on the charging case body 10, capable of applying force to the Bluetooth earphone 200 placed within the earphone slot 11 to stably secure it within the slot.

[0034] See Figure 4 The Bluetooth earphones 200 come in pairs, including a left earphone and a right earphone. The charging case body 10 has two open earphone slots 11 arranged side-by-side, each holding one earphone. Optionally, the Bluetooth earphones 200 are clip-on earphones, with gemstones or other ornaments inlaid on the clip arms. The open structure of the earphone slots 11 allows the ornaments on the clip arms to be exposed when the Bluetooth earphones 200 are inserted, enhancing the overall aesthetics of the Bluetooth earphone assembly.

[0035] like Figure 1 As shown, each earphone slot 11 is provided with a pair of charging electrodes 12, one charging electrode 12 as the positive terminal and the other charging electrode 12 as the negative terminal. The two charging electrodes 12 correspond to and contact the charging contacts on the Bluetooth earphone 200, thereby forming a charging circuit. Figure 2As shown, a battery 103 and an electronic control board 104 are installed inside the charging case body 10. The charging electrode 12 is electrically connected to the electronic control board 104, and the charging electrode 12 is fixed on the electronic control board 104, with its end protruding from the bottom of the earphone slot 11. Optionally, the charging electrode 12 is a spring pin. Due to the small internal space of the charging case body 10, an insulating sleeve 121 is provided on the outer side of the base of the charging electrode 12 to prevent short circuits caused by contact between the charging electrode 12 and other electronic components. Thus, the insulating sleeve 121 eliminates the risk of short circuits between the charging electrode 12 and other electronic components and provides guidance and support for the extension and retraction of the charging electrode 12.

[0036] For details, please refer to Figure 2 The charging compartment body 10 includes a first housing 101 and a second housing 102, which are connected to form a receiving cavity. The battery 103 and the electronic control board 104 are both installed within the receiving cavity. The first housing 101 is located below the second housing 102 and has mounting posts. The electronic control board 104 is fixed to the mounting posts by screws or other fasteners. The battery 103 is placed inside the first housing 101 and below the electronic control board 104. Optionally, the battery 103 is bonded and fixed within the receiving cavity using an adhesive 105 made of ethylene-vinyl acetate copolymer (EVA) or other materials. The battery 103 is a rechargeable battery such as a lithium battery. The electronic control board 104 has a charging interface for connecting to an external power source via a charging cable to charge the battery 103.

[0037] The earphone slot 11 is ergonomically designed, providing a distinct "click" feel when the Bluetooth earphone 200 is inserted into it. The charging electrode 12 can be located at the bottom or on the side of the earphone slot 11. For example, in some embodiments, see [reference needed]. Figure 1 At the bottom of each earphone slot 11, an upwardly protruding electrode post is provided as a charging electrode 12. Correspondingly, a charging contact is provided at the bottom of the portion of the Bluetooth earphone 200 inserted into the earphone slot 11. In some other embodiments, the charging electrode 12 is located on the side wall of the earphone slot 11, and correspondingly, a charging contact is provided on the side of the Bluetooth earphone 200.

[0038] Typically, to facilitate insertion of the Bluetooth headset 200 into the earphone slot 11, there is a gap between the inner wall of the earphone slot 11 and the Bluetooth headset 200. Therefore, during charging, vibration may cause the charging electrode 12 to separate from the charging contacts, affecting the charging effect. In other words, after the Bluetooth headset 200 is inserted into the earphone slot 11, it is not securely positioned solely by the wall of the earphone slot 11. To address this, the Bluetooth headset charging case provided in this embodiment adds a limiting member 20 to the charging case body 10. In addition to being positioned by the wall of the earphone slot 11, the limiting member 20 applies force to the Bluetooth headset 200 within the earphone slot 11, stably fixing the Bluetooth headset 200 within the earphone slot 11 and maintaining contact between the charging electrode 12 and the charging contacts.

[0039] In some alternative embodiments, such as Figure 2 and Figure 3 The limiting member 20 and the charging case body 10 are separately disposed but fixedly connected. In some alternative embodiments, the limiting member 20 and the charging case body 10 are an integral structure. For example, the limiting member 20 is a convex surface protruding from the charging case body 10, with one convex surface for each earphone slot 11. Each convex surface can provide a lateral force to the Bluetooth earphone 200 stored in the corresponding earphone slot 11. The direction of the lateral force is perpendicular to the plane of symmetry of the two earphone slots 11. The direction of the lateral force mentioned below is the same and will not be described in detail.

[0040] After the Bluetooth earphone 200 is inserted into the earphone slot 11, the slot wall of the earphone slot 11 forms a constraint on the Bluetooth earphone 200. The limiting member 20 abuts against the Bluetooth earphone 200, providing a pushing force from between the two earphone slots 11 towards the Bluetooth earphone 200 housed within the earphone slots 11. Specifically, both the left and right earphones are pushed by the limiting member 20; that is, the limiting member 20 provides opposite forces from between the two earphone slots 11 to both sides, simultaneously pushing against both Bluetooth earphones 200 to cooperate with the earphone slots 11 and keep the Bluetooth earphone 200 stable within the earphone slots 11. Figure 4As shown, when the Bluetooth headset 200 is inserted into the earphone slot 11, the contact surface with the limiting member 20 is an arc-shaped surface. The limiting member 20 pushes against the Bluetooth headset 200, providing continuous pressure to the Bluetooth headset 200, increasing the static friction between the Bluetooth headset 200 and the inner wall of the earphone slot 11 to resist the influence of external shaking, ensuring that the charging contacts of the Bluetooth headset 200 and the charging electrodes 12 in the earphone slot 11 always maintain precise and stable contact. Therefore, the Bluetooth headset 200 will not be interrupted during charging due to unstable charging contact, thus preventing erroneous Bluetooth reconnection operations with mobile phones and other electronic devices when the Bluetooth headset 200 is in the earphone slot 11. It can be understood that when only one Bluetooth headset 200 is inserted into the two earphone slots 11, the limiting member 20 can provide a pushing force only to that Bluetooth headset 200, cooperating with the earphone slot 11 to keep the Bluetooth headset 200 stable within the earphone slot 11. For example, if only the left earphone is inserted into the corresponding earphone slot 11, and the earphone slot 11 for inserting the right earphone is empty, then the limiting member 20 only abuts against the left earphone.

[0041] The Bluetooth earphone charging case provided in this application embodiment has an open-structure earphone slot 11 in the main body 10. When the Bluetooth earphone 200 is inserted into the earphone slot 11, the Bluetooth earphone 200 can be displayed to the outside. Furthermore, the limiting member 20 provided on the main body 10 can provide force to the Bluetooth earphone 200, so that the Bluetooth earphone 200 is stable in the earphone slot 11, preventing the Bluetooth earphone 200 from reconnecting to the electronic device due to loosening, thereby improving the user's charging experience.

[0042] like Figures 1 to 3 An arched structure 13 is provided between two adjacent earphone slots 11, and a limiting member 20 is fixed on the arched structure 13 to apply at least a lateral force to the Bluetooth earphone 200 placed in the earphone slot 11.

[0043] See Figure 4 With the direction in which the Bluetooth headset 200 is inserted into the headphone slot 11 as the vertical direction, it is perpendicular to the direction of the lateral force. When the Bluetooth headset 200 is inserted into the headphone slot 11, in addition to the lateral force provided by the slot wall of the headphone slot 11, the limiting member 20 can also provide a lateral force to the Bluetooth headset 200. Thus, by using forces in different directions, a stable constraint is achieved on the Bluetooth headset 200, reducing the impact of external vibration on charging.

[0044] An arched structure 13 is located between the two earphone slots 11 and extends above the opening of the earphone slots 11. In some embodiments, a limiting member 20 is fixed to the arched structure 13, and a convex surface is formed on the arched structure 13 in the direction facing the earphone slots 11 to push against the Bluetooth earphone 200. In still other embodiments, the limiting member 20 is an arc-shaped concave surface that is adapted to the outer wall of the clamping arm of the Bluetooth earphone 200, so that when the Bluetooth earphone 200 is inserted into the earphone slots 11, the arc-shaped concave surface is in close contact with the clamping arm of the Bluetooth earphone 200, so that the arc-shaped concave surface provides force to the Bluetooth earphone 200 in both horizontal and vertical directions.

[0045] When the user needs to charge the Bluetooth earphones 200, they place the left and right earphones into the corresponding earphone slots 11 of the charging case body 10. During this process, the inner sides of the two Bluetooth earphones 200 will press against the limiting member 20 located in the middle. Since the limiting member 20 abuts against the two Bluetooth earphones 200, it will generate a continuous and lateral reaction force on the two Bluetooth earphones 200, acting on each earphone 200 respectively. This lateral force is perpendicular to the plane of symmetry between the two earphone slots 11. The lateral force of the limiting member 20 on the Bluetooth earphones 200 will push the Bluetooth earphones 200 tightly against the outer wall of their respective earphone slots 11, thereby generating sufficient friction and pressure to prevent the Bluetooth earphones 200 from losing contact with the charging electrodes 12 due to loosening during wearing and movement. Here, the outer wall of the earphone slot 11 refers to the side of the earphone slot 11 away from the limiting member 20.

[0046] Specifically, such as Figure 1 and Figure 3 As shown, the arched structure 13 has a lanyard hole 14, and a wearing component 30 is inserted into the lanyard hole 14. Optionally, the wearing component 30 can be a chain, lanyard, or hook, used to wear the charging case body 10 on the user or hang it on an object. Thus, the Bluetooth headset charging case can be worn around the neck or wrist, or hung on a backpack, using the wearing component 30 such as a chain, lanyard, or hook. This not only makes it extremely convenient to carry and less likely to be lost, but also transforms the entire Bluetooth headset charging case into a technological accessory. At the same time, since the earphone slot 11 has an open structure, part of the shape of the Bluetooth headset 200 can be displayed when charging, satisfying the user's aesthetic and display needs.

[0047] In some specific embodiments, such as Figure 1 and Figure 3As shown, the arched structure 13 has mounting holes 15, and the limiting member 20 is snapped into the mounting holes 15. For example, the opposite side of the mounting hole 15 has a limiting post 16, and the opposite side of the limiting member 20 has blind hole-shaped limiting holes 22, or the limiting member 20 has only one through hole-shaped limiting hole 22. The limiting post 16 is inserted into the limiting hole 22 to fix the limiting member 20 to the mounting hole 15. Thus, one limiting member 20 can provide force for two Bluetooth headsets 200. Alternatively, the mounting hole 15 has an insertion hole in its wall, and the limiting member 20 has a connecting post. The connecting post is inserted into the insertion hole to fix the limiting member 20 and the charging case body 10. In some optional embodiments, the limiting member 20 includes two limiting units, which are respectively located on opposite sides of the arched structure 13. For example, each limiting unit is hemispherical and is set on the side of the arch structure 13 facing the earphone slot 11 by bonding or integral molding. In this case, there is no need to set the mounting hole 15 on the arch structure 13.

[0048] With the limiting component 20 fixed in place within the mounting hole 15, refer to Figure 1 and Figure 3 The mounting hole 15 is connected to the lanyard hole 14. The lanyard hole 14 is strip-shaped, and the mounting hole 15 is a round hole located at the bottom end of the lanyard hole 14. In some alternative embodiments, the mounting hole 15 and the lanyard hole 14 are two independently provided holes and are not connected. In this case, the mounting hole 15 is located below the lanyard hole 14.

[0049] like Figure 1 and Figure 4 As shown, the limiting member 20 has a pushing surface 21 extending into the earphone slots 11 on both sides, and the pushing surface 21 is used to abut against the Bluetooth earphone 200 placed in the earphone slot 11. The limiting member 20 is spherical or ellipsoidal in shape. For example, the limiting member 20 is spherical, and its spherical surface serves as the pushing surface 21 to abut against the Bluetooth earphone 200. Alternatively, the limiting member 20 can also be hemispherical or ellipsoidal, as long as it can apply a pushing force to the clamping arms of the Bluetooth earphone 200 in the earphone slot 11. For example, there are two limiting members 20, each of which is hemispherical and is located on opposite sides of the arched structure 13.

[0050] The limiting member 20 is an elastic member. When the earphone slot 11 is empty, the elastic member is in its natural position under force. When the user inserts the Bluetooth earphone 200 into the earphone slot 11, the side wall of the Bluetooth earphone 200 compresses the elastic member, causing it to deform slightly. The compressed elastic member stores elastic potential energy, generating a rebound force opposite to the direction of deformation, attempting to return to its initial state. Thus, the elastic member provides a continuous lateral force to the Bluetooth earphone 200, pressing it firmly against the slot wall of the earphone slot 11.

[0051] Optionally, the elastic element can be made of silicone, rubber, or thermoplastic elastic material, possessing a certain degree of elasticity and good durability. When the Bluetooth headset 200 comes into contact with the elastic element, the flexibility of the elastic element prevents scratches on the surface of the Bluetooth headset 200. The elastic element can apply positive pressure to the Bluetooth headset 200, that is, a force perpendicular to the contact surface, pressing the Bluetooth headset 200 firmly against the groove wall of the earphone slot 11. For example, the limiting member 20 is a spherical elastic element, with its spherical surface facing the two grooves serving as a pushing surface 21, abutting against the Bluetooth headset 200 housed in the earphone slot 11. It can be understood that when only one Bluetooth headset 200 is inserted into the earphone slot 11, the limiting member 20 can provide constraint for the Bluetooth headset 200 within the earphone slot 11.

[0052] The limiting component 20 can be a spring sheet, a V-shaped elastic arm, etc., set between the two earphone slots 11. As long as it can apply opposite lateral forces to the two Bluetooth earphones 200, it can stabilize the Bluetooth earphones 200 in the earphone slots 11.

[0053] In some specific embodiments of this application, such as Figure 1 and Figure 2 As shown, the Bluetooth earphone charging case also includes a magnetic component 40, which is fixed to the charging case body 10 and positioned near the charging electrode 12 so that it can attract the magnet on the Bluetooth earphone 200 when the Bluetooth earphone 200 is charging.

[0054] like Figure 1 and Figure 2 As shown, each earphone slot 11 is provided with a magnetic element 40. For example, the magnetic element 40 is disposed between two charging electrodes 12 within the same earphone slot 11, and correspondingly, a magnet is disposed between the charging contacts of the Bluetooth earphone 200. When the Bluetooth earphone 200 is inserted into the earphone slot 11 for charging, the magnetic attraction between the magnetic element 40 and the magnet keeps the charging contacts and charging electrodes 12 in contact, preventing them from separating during charging and causing charging failure, and also securing the Bluetooth earphone 200 to prevent it from falling out of the earphone slot 11. It can be understood that there can be multiple magnetic elements 40 disposed in each earphone slot 11, with the multiple magnetic elements 40 distributed around the two charging electrodes 12 within the same earphone slot 11.

[0055] This application also provides a Bluetooth headset component, such as... Figure 4 As shown, it includes a Bluetooth headset 200 and a Bluetooth headset charging case as described above. The Bluetooth headset 200 can be plugged into and charged in the earphone slot 11.

[0056] The Bluetooth headset 200 can be inserted into the earphone slot 11 for charging. The limiting member 20 ensures a stable and reliable physical and electrical connection between the charging contacts of the Bluetooth headset 200 and the charging electrodes 12 within the earphone slot 11, preventing poor contact due to shaking. This ensures continuous charging and prevents the Bluetooth headset 200 from automatically reconnecting to mobile phones or other electronic devices after disconnecting from charging. Furthermore, the limiting member 20 and the wall of the earphone slot 11 work together to hold the Bluetooth headset 200 within the earphone slot 11, preventing it from easily loosening or falling out even when the user wears the Bluetooth headset charging case while walking or engaging in slight movement using the wearing member 30.

[0057] The Bluetooth headset component provided in this application embodiment allows the Bluetooth headset 200 to be charged via the Bluetooth headset charging case. During charging, the exposed portion can showcase the shape of the Bluetooth headset 200. The limiting member 20 can also ensure the continuity of charging and prevent the charging contacts of the Bluetooth headset 200 from detaching from the charging electrodes 12 in the earphone slot 11.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
