Technical Field
[0001] The utility model relates to the technical field of Bluetooth earphone boxes, in particular to a hinge structure and a Bluetooth earphone box. Background Art
[0002] In the design of modern mobile devices, hinge structures play a vital role, especially in devices that need to be opened and closed frequently, such as Bluetooth headset boxes. The hinge not only needs to provide stable support, but also needs to ensure the smoothness and precision of the device during the opening and closing process. The traditional hinge structure usually includes a hinge shaft and a hinge arm rotatably connected to it. These components realize the rotation function through the cooperation of the hinge hole and the hinge shaft.
[0003] However, in order to provide a better user experience, the hinge structure also needs to have certain damping characteristics to make the opening and closing action smoother and more controllable. Existing solutions usually involve additional damping parts, such as liquid dampers or friction dampers, assembled on the hinge axis. Although these damping parts can provide the required damping effect, they have problems such as complex assembly, high cost, and difficult maintenance.
[0004] In addition, traditional hinge structures often lack sufficient flexibility and innovation in design, making it difficult to meet the high requirements of precision and consistency for modern mobile devices. Especially when it comes to parts that require high-precision matching, such as the matching of hinge holes and hinge axes, traditional designs are difficult to ensure consistency and reliability during mass production.

[0009] Furthermore, a deformation notch is provided in the hinge hole, and the elastic buckle is located in the deformation notch.
[0010] Furthermore, the elastic buckle includes an elastic portion and a clamping portion which are connected to each other, the elastic portion is connected to the hinged arm, and the clamping portion is clamped to the tooth groove.
[0011] Furthermore, a side of the elastic portion close to the hinge axis is an arc surface.
[0012] Furthermore, the radius of curvature of the arc surface is greater than or equal to the radius of curvature of the inner wall surface of the hinge hole.
[0013] Furthermore, a limit baffle is provided at the end of the articulated shaft, and the limit baffle is used to abut against the articulated arm.
[0014] Furthermore, a sliding member is provided between the limit baffle and the hinged arm.

[0016] The beneficial effects of the utility model are as follows: the hinge structure and the Bluetooth headset box provided by the utility model have the characteristics of simple structure, low cost, easy maintenance and good damping performance.

[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0025] Please refer to Figures 1 to 5 A hinge structure comprises a hinge shaft 3 and a hinge arm 22 rotatably connected to the hinge shaft 3, the hinge arm 22 is provided with a hinge hole 221, the hinge shaft 3 is sleeved in the hinge hole 221, the hinge shaft 3 is provided with tooth grooves 31 evenly distributed around its central axis, the hinge hole 221 is provided with an elastic buckle 23 engaged with the tooth groove 31, the elastic buckle 23 is integrally formed in the hinge hole 221, and the tooth groove 31 is integrally formed on the hinge shaft 3.
[0026] As can be seen from the above description, the beneficial effect of the utility model is that a new damping mechanism is realized by providing a tooth groove 31 on the hinge shaft 3 and providing an elastic buckle 23 engaged therewith in the hinge hole 221. This design allows the rotation between the hinge arm 22 and the hinge shaft 3 to have a damping effect without the need for an additional damping member. The integrally formed tooth groove 31 and elastic buckle 23 simplify the manufacturing process, reduce assembly costs, and improve the overall consistency and reliability of the product.
[0027] Furthermore, there are multiple elastic buckles 23.
[0028] As can be seen from the above description, increasing the number of elastic buckles 23 can provide a more uniform and stable damping effect. The design of multiple elastic buckles 23 can make the resistance distribution of the hinge structure more uniform during the rotation process, thereby providing a smoother and more consistent user experience.
[0029] Furthermore, the plurality of elastic buckles 23 are centrally symmetrically distributed relative to the central axis of the hinge hole 221 .
[0030] As can be seen from the above description, the elastic buckle 23 is symmetrically distributed with respect to the center axis of the hinge hole 221, which can ensure the balance and stability of the hinge structure during rotation. This symmetrical layout helps to reduce the eccentric torque during rotation, thereby improving the durability of the hinge structure and the smoothness of rotation.
[0031] Furthermore, a deformation notch 222 is provided in the hinge hole 221 , and the elastic buckle 23 is located in the deformation notch 222 .
[0032] As can be seen from the above description, by providing a deformation notch 222 in the hinge hole 221 and positioning the elastic buckle 23 in the deformation notch 222, the deformation space of the elastic buckle 23 can be increased, thereby providing a more refined damping adjustment capability. This design allows the elastic buckle 23 to have more elastic deformation when engaging the tooth groove 31, so as to adapt to different rotation speeds and damping requirements.
[0033] Furthermore, the elastic buckle 23 includes an elastic portion 231 and a clamping portion 232 which are connected to each other. The elastic portion 231 is connected to the hinge arm 22 , and the clamping portion 232 is clamped to the tooth groove 31 .
[0034] As can be seen from the above description, the elastic buckle 23 is composed of a connected elastic portion 231 and a clamping portion 232, wherein the elastic portion 231 is connected to the hinge arm 22, and the clamping portion 232 is clamped with the tooth groove 31. This structural design allows the elastic buckle 23 to effectively absorb energy during the rotation process and provide a damping effect through elastic deformation. At the same time, the clamping of the clamping portion 232 and the tooth groove 31 ensures a stable connection between the hinge arm 22 and the hinge shaft 3.
[0035] Furthermore, a side of the elastic portion 231 close to the hinge shaft 3 is an arc surface.
[0036] As can be seen from the above description, the arc surface design of the elastic part 231 close to the hinge shaft 3 can reduce the friction between the elastic part 231 and the hinge shaft 3, thereby reducing the energy loss during the rotation process. The shape of the arc surface helps to achieve smoother elastic deformation and provide a more consistent damping effect.
[0037] Furthermore, the radius of curvature of the arc surface is greater than or equal to the radius of curvature of the inner wall surface of the hinge hole 221 .
[0038] As can be seen from the above description, the radius of curvature of the arc surface is greater than or equal to the radius of curvature of the inner wall surface of the hinge hole 221, which can ensure that the elastic part 231 will not interfere with the inner wall of the hinge hole 221 during the deformation process, thereby avoiding possible wear and damage. This design helps to improve the service life and reliability of the hinge structure.
[0039] Furthermore, a limit baffle 32 is provided at the end of the hinge shaft 3 , and the limit baffle 32 is used to abut against the hinge arm 22 .
[0040] As can be seen from the above description, the limit baffle 32 at the end of the hinge shaft 3 is designed to abut against the hinge arm 22, thereby preventing the hinge arm 22 from loosening along the axial direction of the hinge shaft 3, thereby ensuring the stability and safety of the hinge structure.
[0041] Furthermore, a sliding member is provided between the limit baffle 32 and the hinged arm 22 .
[0042] As can be seen from the above description, the provision of a sliding member between the limit baffle 32 and the hinge arm 22 can reduce direct contact and friction between the two, thereby reducing noise and wear. The presence of the sliding member provides a buffer mechanism, which helps to extend the service life of the hinge structure and improve the user experience.
[0043] A Bluetooth earphone box comprises the hinge structure mentioned above.
[0044] From the above description, it can be seen that the hinge structure applied to the Bluetooth headset box can provide a novel opening and closing experience. Since the hinge structure has built-in damping characteristics and limit functions, the opening and closing of the Bluetooth headset box will be smoother and more stable, and at the same time have a longer service life and higher reliability.
[0045] Please refer to Figures 1 to 5 , Embodiment 1 of the present utility model is: a Bluetooth headset box, comprising an electronic control housing 1, two storage housings 2 and a hinge structure, wherein the electronic control housing 1 has a built-in power supply assembly; each of the two storage housings 2 is provided with a charging slot 21 for placing the Bluetooth headset, and the charging slot 21 is provided with charging contacts that match the charging interface of the Bluetooth headset; the power supply assembly is electrically connected to the charging contacts in the charging slot 21 to realize charging of the Bluetooth headset; the two storage housings 2 are respectively hinged to the electronic control housing 1 through the hinge structure; when the two storage housings 2 are flipped to a stacked state, the two charging slots 21 cover each other to form a closed storage space (such as Figure 2 In addition, the two storage shells 2 can be folded in reverse so that the two charging slots 21 are exposed (as shown in FIG. Figure 3As shown), in this state, it is convenient for users to take and put the Bluetooth headset, which enriches the use scenarios of the Bluetooth headset box; specifically, the hinge structure includes a hinge shaft 3 and a hinge arm 22 rotatably connected to the hinge shaft 3; one end of the hinge shaft 3 is installed on the electronic control housing 1; the hinge arm 22 is installed on the storage housing 2, each of the storage housings 2 is provided with two hinge arms 22, and the hinge arm 22 is provided with a hinge hole 221, and the hinge shaft 3 is sleeved Connected to the hinge hole 221, the hinge shaft 3 is provided with tooth grooves 31 evenly distributed around its central axis, and the hinge hole 221 is provided with an elastic buckle 23 engaged with the tooth grooves 31, and the elastic buckle 23 is integrally formed in the hinge hole 221, and the tooth groove 31 is integrally formed on the hinge shaft 3; it can be understood that by providing the tooth groove 31 on the hinge shaft 3 and providing the elastic buckle 23 engaged therewith in the hinge hole 221, a new damping mechanism is realized. This design allows the rotation between the hinge arm 22 and the hinge shaft 3 to have a damping effect at the same time without the need for an additional damping member. The integrally formed tooth grooves 31 and elastic buckle 23 simplify the manufacturing process, reduce assembly costs, and improve the overall consistency and reliability of the product.
[0046] As an option, there are multiple elastic buckles 23, and increasing the number of elastic buckles 23 can provide a more uniform and stable damping effect. The design of multiple elastic buckles 23 can make the resistance distribution of the hinge structure more uniform during the rotation process, thereby providing a smoother and more consistent user experience; specifically in this embodiment, the number of the elastic buckles 23 of each hinged arm 22 is two, and the two elastic buckles 23 are centrally symmetrically distributed relative to the central axis of the hinge hole 221, so that the balance and stability of the hinge structure during rotation can be ensured. This symmetrical layout helps to reduce the eccentric torque during the rotation process, thereby improving the durability of the hinge structure and the smoothness of the rotation.
[0047] Preferably, a deformation notch 222 is further provided in the hinge hole 221, and the elastic buckle 23 is located in the deformation notch 222, so that the deformation space of the elastic buckle 23 can be increased, thereby providing a more refined damping adjustment capability. This design allows the elastic buckle 23 to have more elastic deformation when engaging the tooth groove 31 to adapt to different rotation speeds and damping requirements; specifically, the elastic buckle 23 includes a connected elastic portion 231 and a clamping portion 232, the elastic portion 231 is connected to the hinge arm 22, and the clamping portion 232 is engaged with the tooth groove 31. This structural design allows the elastic buckle 23 to effectively absorb energy during the rotation process and provide a damping effect through elastic deformation. At the same time, the engagement between the clamping portion 232 and the tooth groove 31 ensures a stable connection between the hinge arm 22 and the hinge shaft 3; more specifically, the side of the elastic portion 231 close to the hinge shaft 3 is an arc surface, so that the friction between the elastic portion 231 and the hinge shaft 3 can be reduced, thereby reducing energy loss during rotation. The shape of the arc surface helps to achieve smoother elastic deformation and provide a more consistent damping effect; in detail, the radius of curvature of the arc surface is greater than or equal to the radius of curvature of the inner wall of the hinge hole 221, so that it can be ensured that the elastic portion 231 will not interfere with the inner wall of the hinge hole 221 during the deformation process, thereby avoiding possible wear and damage. This design helps to improve the service life and reliability of the hinge structure.
[0048] Preferably, a limit baffle 32 is also provided at the end of the articulated shaft 3, and the limit baffle 32 is used to abut against the articulated arm 22. The limit baffle 32 at the end of the articulated shaft 3 is designed to abut against the articulated arm 22, so as to prevent the articulated arm 22 from loosening along the axial direction of the articulated shaft 3, thereby ensuring the stability and safety of the hinge structure. Specifically, the limit baffle 32 is arranged at the end of the articulated shaft 3 away from the electronic control housing 1.
[0049] Optionally, a sliding member (not shown) may be provided between the limit baffle 32 and the articulated arm 22, so that direct contact and friction between the two can be reduced, thereby reducing noise and wear. The existence of the sliding member provides a buffer mechanism, which helps to extend the service life of the hinge structure and improve the user experience; the sliding member includes but is not limited to bearings, gaskets, sliders, guide rails, pulleys, washers, grease or lubricating films, etc., which can be selected according to actual application requirements and are not described in detail here.
[0050] In summary, the hinge structure and Bluetooth headset box provided by the utility model have the characteristics of simple structure, low cost, easy maintenance and good damping performance. A new damping mechanism is realized by setting a tooth groove on the hinge shaft and setting an elastic clip connected with it in the hinge hole. This design allows the rotation between the hinge arm and the hinge shaft to have a damping effect at the same time without the need for additional damping parts. The one-piece molded tooth groove and elastic clip simplify the manufacturing process, reduce assembly costs, and improve the overall consistency and reliability of the product; the hinge structure is applied to the Bluetooth headset box to provide a novel opening and closing experience. Because the hinge structure has built-in damping characteristics and limit functions, the opening and closing of the Bluetooth headset box will be smoother and more stable, and it will have a longer service life and higher reliability.
