Description

Technical Field

[0001] The utility model relates to the technical field of headphones, in particular to an ear shell rotating structure and a headphone. Background Art

[0002] The difference between headphones and in-ear headphones is that headphones are worn on the head and not inserted into the ear canal. Compared with in-ear headphones, they can provide consumers with better wearing comfort.

[0003] As the technological innovation and upgrading of consumer electronic products continue to accelerate, consumers' requirements for the wearing comfort of headphones are getting higher and higher.

[0004] Existing headphones usually include an ear shell and a bracket, and the ear shell and the bracket are rotatably connected, so that different wearers can adjust the wearing angle they need to improve wearing comfort. In actual research, it was found that the existing ear shell and the bracket are mainly rotated by a shaft. Specifically, the shaft is installed and locked on the ear shell with a screw. The locking relies on the plastic ear shell and the shaft to limit the screw, and there is no limit structure between the screw and the bracket. In this way, when the screw locking torque is too large, it will cause the shaft to break, get stuck, and rotate unsmoothly, making it difficult to control the torque parameters. Utility Model Content

[0005] In response to the above-mentioned problems such as excessive torque causing shaft breakage, jamming, uneven rotation and difficulty in controlling torque parameters, the utility model provides an ear shell rotation structure and a headphone, which uses a half-thread screw to lock and limit the screw and the bracket through a threaded connection, replacing the traditional unlimited position structure between the screw and the bracket. It has a larger range of adjustable torque parameters and solves the adverse problems caused by excessive torque.

[0006] In order to solve the above technical problems, the specific solutions provided by the utility model are as follows:

[0007] An ear shell rotating structure comprises an ear shell, a bracket, a rotating shaft and a screw;

[0008] The ear shell is provided with a first mounting hole for mounting the rotating shaft, and the outer periphery of the first mounting hole is provided with a first connecting hole for the screw to pass through;

[0009] The bracket is provided with a connecting portion, the shaft is provided with a second mounting hole for mounting the connecting portion in the axial direction, the shaft is provided with a second connecting hole for the screw to pass through in the circumferential direction, and the connecting portion is provided with a third connecting hole for the screw to pass through;

[0010] Wherein, the screw is a half-thread screw, and the screw passes through the first connecting hole, the second connecting hole and the third connecting hole in sequence, and the hole wall of the third connecting hole is formed with an internal thread for threaded connection with the screw.

[0011] In some embodiments, the screw includes a nut portion, a smooth rod portion, and a threaded portion connected in sequence, wherein the diameter of the smooth rod portion is larger than the diameter of the threaded portion, thereby limiting the threaded connection relationship between the threaded portion and the third connecting hole, thereby limiting the locking between the screw and the bracket.

[0012] In some embodiments, the diameter of the smooth rod portion is larger than the diameter of the third connecting hole, thereby ensuring that the threaded connection between the threaded portion and the bracket is in place, and also limiting the locking between the screw and the bracket.

[0013] In some embodiments, a gap is provided between the nut portion and the edge of the first connecting hole to facilitate the rotation adjustment of the ear shell and improve the smoothness of the rotation of the ear shell.

[0014] In some embodiments, the first connecting hole is an elongated hole, and the direction in which the ear shell rotates around the rotating shaft is the same as the extending direction of the first connecting hole. The first connecting hole guides the rotation of the ear shell and limits the rotation displacement, thereby improving the convenience of rotation adjustment.

[0015] In some embodiments, the rotating shaft includes a main shaft portion and a shaft cap portion connected to the main shaft portion, and the diameter of the shaft cap portion is greater than the diameter of the main shaft portion;

[0016] The first mounting hole is a through hole, the main shaft portion is located in the first mounting hole, and the shaft cap portion is limited to the edge of the first mounting hole;

[0017] The second mounting hole and the second connecting hole are both arranged on the main shaft part, and the shaft cap part plays a limiting role in the installation of the rotating shaft, which is beneficial to improving the installation convenience and installation stability of the rotating shaft.

[0018] In some embodiments, a silicone ring is further included, and an installation groove for installing the silicone ring is opened on the circumference of the main shaft part. The silicone ring has a certain resistance to the rotation process of the ear shell, and also plays a role of sealing connection to prevent external dust and the like from entering the interior of the shell, thereby improving the stability and service life of the headset.

[0019] In some embodiments, the silicone ring is installed in the installation groove with interference fit, ensuring that the silicone ring plays a role of resistance and sealing connection during the rotation of the ear shell.

[0020] The present application also provides a headset, comprising a headband and the ear shell rotating structure described in any one of the above items, wherein the bracket is connected to the end of the headband, the headband serves to be worn, and the bracket serves to establish a connection between the ear shell and the headband, thereby realizing the wearing and adjustment functions of the headset.

[0021] In some embodiments, the bracket is rotatably connected to the end of the headband, which can achieve rotational adjustment of the ear shell in another direction, making it easier to store or use.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the ear shell rotation structure and the headset provided by the present invention adopt a half-thread screw, so that the screw and the bracket are locked and limited by a threaded connection, replacing the traditional method of an unlimited structure between the screw and the bracket, and having a larger range of adjustable torque parameters, and solving the problems of shaft breakage, jamming, uneven rotation and difficulty in controlling torque parameters caused by excessive torque, thereby improving the rotation stability and the service life of the shaft.

[0036] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0037] 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 present invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, an ear shell rotation structure includes an ear shell, a bracket, a rotating shaft and a screw; a first mounting hole for installing the rotating shaft is provided on the ear shell, and a first connecting hole for the screw to pass through is provided on the outer periphery of the first mounting hole; a connecting portion is provided on the bracket, a second mounting hole for installing the connecting portion is provided in the axial direction of the rotating shaft, a second connecting hole for the screw to pass through is provided in the circumferential direction of the rotating shaft, and a third connecting hole for the screw to pass through is provided on the connecting portion; wherein the screw is a half-thread screw, and the screw passes through the first connecting hole, the second connecting hole and the third connecting hole in sequence, and the hole wall of the third connecting hole is formed with an internal thread for threaded connection with the screw.

[0039] An ear shell rotation structure provided in this embodiment adopts a half-thread screw, which realizes locking and limiting between the screw and the bracket through a threaded connection, replacing the unlimited structure between the traditional screw and the bracket. It has a large range of adjustable torque parameters and solves the problems of shaft breakage, jamming, uneven rotation and difficulty in controlling torque parameters caused by excessive torque, thereby improving the rotation stability and the service life of the shaft.

[0040] Embodiment 1:

[0041] like Figure 1-Figure 7As shown, an ear shell 1 rotation structure includes an ear shell 1, a bracket 2, a rotating shaft 3 and a screw 4. The ear shell 1 is used to achieve a rotational connection relationship with the bracket 2 under the action of the rotating shaft 3 and the screw 4, so that consumers can rotate the ear shell 1 to adjust the wearing angle according to their own wearing needs to improve wearing comfort.

[0042] A first mounting hole 11 for mounting the rotating shaft 3 is provided on the ear shell 1, and the first mounting hole 11 is adapted to the shape of the rotating shaft 3. For example, the rotating shaft 3 is a cylindrical structure, and the first mounting hole 11 is a cylindrical hole, so that the rotating shaft 3 can be fully adapted and installed in the first mounting hole 11. Combined with the structure of traditional headphones, there are usually two rotating connections between the ear shell 1 and the bracket 2. Therefore, two first mounting holes 11 are symmetrically provided on the ear shell 1, and a rotating shaft 3 is installed in each of the two first mounting holes 11.

[0043] A first connecting hole 12 for the screw 4 to pass through is arranged on the periphery of the first mounting hole 11. It can be understood that the first mounting hole 11 includes at least one opening, and the first connecting hole 12 is a through hole. The first connecting hole 12 is arranged on the periphery of the first mounting hole 11, that is, the opening direction of the first connecting hole 12 is perpendicular to the opening direction of the first mounting hole 11.

[0044] The bracket 2 is provided with a connecting portion 21, which is used to connect with the rotating shaft 3. A second mounting hole 31 for mounting the connecting portion 21 is provided in the axial direction of the rotating shaft 3, that is, the connecting portion 21 on the bracket 2 is installed in the second mounting hole 31 of the rotating shaft 3, and the rotating shaft 3 is installed in the first mounting hole 11 of the ear shell 1. A second connecting hole 32 for the screw 4 to pass through is provided in the circumferential direction of the rotating shaft 3, and a third connecting hole 22 for the screw 4 to pass through is provided on the connecting portion 21.

[0045] After the connecting portion 21 on the bracket 2 is installed on the second mounting hole 31 of the rotating shaft 3 and the rotating shaft 3 is installed on the first mounting hole 11 of the ear shell 1, it can be known that the first connecting hole 12, the second connecting hole 32 and the third connecting hole 22 are in a corresponding relationship, so that the screw 4 can pass through the first connecting hole 12, the second connecting hole 32 and the third connecting hole 22 in sequence.

[0046] In this example, the screw 4 is a half-thread screw. After the screw 4 passes through the first connecting hole 12 and the second connecting hole 32 in sequence, the threaded portion 43 of the screw 4 and the internal thread at the hole wall of the third connecting hole 22 act as a threaded connection, so that the screw 4 and the bracket 2 are locked and limited by the threaded connection, replacing the traditional method of having an unlimited structure between the screw 4 and the bracket 2.

[0047] After the ear shell 1, the bracket 2, the shaft 3 and the screw 4 are assembled, the screw 4 and the bracket 2 have a locking and limiting effect. At the same time, the screw 4 also establishes a certain connection and limiting effect with the shaft 3 through the second connecting hole 32. As for the ear shell 1, when the ear shell 1 rotates around the shaft 3, the screw 4 will be located at different positions in the first connecting hole 12, that is, the first connecting hole 12 guides and limits the rotation displacement of the ear shell 1, thereby improving the convenience of rotation adjustment of the ear shell 1.

[0048] Embodiment 2:

[0049] refer to Figure 6 and Figure 7 In this example, the screw 4 includes a nut portion 41, a rod portion 42 and a threaded portion 43 connected in sequence, wherein the diameter of the rod portion 42 is larger than the diameter of the threaded portion 43, limiting the threaded connection relationship between the threaded portion 43 and the third connecting hole 22, that is, limiting the locking between the screw 4 and the bracket 2.

[0050] Since the diameter of the smooth rod portion 42 is larger than the diameter of the threaded portion 43, and the threaded portion 43 and the internal thread of the third connecting hole 22 are in a matching connection relationship, after the threaded portion 43 and the third connecting hole 22 are connected in place, the smooth rod portion 42 cannot enter the third connecting hole 22 as the screw 4 continues to be turned, thereby limiting the locking relationship between the screw 4 and the bracket 2.

[0051] In some examples, the diameter of the smooth rod portion 42 is larger than the diameter of the third connection hole 22 , ensuring that the threaded connection between the threaded portion 43 and the bracket 2 is in place, while also limiting the locking between the screw 4 and the bracket 2 .

[0052] After the threaded portion 43 completely enters the third connecting hole 22, since the diameter of the light rod portion 42 is larger than the diameter of the third connecting hole 22, the light rod portion 42 will be limited at the edge of the third connecting hole 22 and cannot enter the third connecting hole 22. While ensuring that the threaded connection between the threaded portion 43 and the bracket 2 is in place, the locking between the screw 4 and the bracket 2 can also be limited.

[0053] There is a gap between the nut portion 41 and the edge of the first connecting hole 12 to facilitate the rotation adjustment of the ear shell 1 and improve the smoothness of the rotation of the ear shell 1.

[0054] In this example, the diameter of the smooth rod part 42 is larger than the diameter of the threaded part 43, so that the smooth rod part 42 can play the role of a stop and limit. The locking and limiting method between the screw 4 and the bracket 2 can adjust the torque parameter range to a larger extent, and can be locked at will to solve the adverse problems caused by excessive torque.

[0055] Embodiment three:

[0056] refer to Figure 2 and Figure 3 In this example, the first connecting hole 12 is a long strip hole. The direction in which the ear shell 1 rotates around the rotating shaft 3 is the same as the extending direction of the first connecting hole 12. The first connecting hole 12 guides the rotation of the ear shell 1 and limits the rotation displacement, thereby improving the convenience of rotation adjustment.

[0057] refer to Figure 5 The rotating shaft 3 includes a main shaft portion 33 and a shaft cap portion 34 connected to the main shaft portion 33, and the diameter of the shaft cap portion 34 is larger than the diameter of the main shaft portion 33; the first mounting hole 11 is a through hole, the main shaft portion 33 is located in the first mounting hole 11, and the shaft cap portion 34 is limited to the edge of the first mounting hole 11; the second mounting hole 31 and the second connecting hole 32 are both arranged on the main shaft portion 33.

[0058] The shaft cap portion 34 can be provided to limit the installation of the rotating shaft 3 , which is beneficial to improving the installation convenience and installation stability of the rotating shaft 3 .

[0059] refer to Figure 7 In some examples, the ear shell 1 rotation structure also includes a silicone ring 5. A mounting groove 35 for mounting the silicone ring 5 is opened on the circumference of the main shaft part 33. The silicone ring 5 has a certain resistance to the rotation process of the ear shell 1, and also plays a role of sealing connection to prevent external dust from entering the shell, thereby improving the stability and service life of the headset.

[0060] Specifically, the silicone ring 5 is installed in the installation groove 35 with interference fit, ensuring that the silicone ring 5 plays a role of resistance and sealing connection during the rotation of the ear shell 1.

[0061] Embodiment 4:

[0062] refer to Figure 8 The present application also provides a headset, including a headband 6 and the ear shell 1 rotating structure in any of the above embodiments, the bracket 2 is connected to the end of the headband 6, the headband 6 plays a wearing role, and the bracket 2 plays a role in establishing the connection between the ear shell 1 and the headband 6, thereby realizing the wearing and adjustment functions of the headset.

[0063] In some examples, the bracket 2 and the end of the headband 6 are rotatably connected, which can realize rotational adjustment of the ear shell 1 in another direction and facilitate storage or use.

[0064] In summary, the utility model provides an ear shell rotation structure and a headset, which adopts a half-thread screw to lock and limit the screw and the bracket through a threaded connection, replacing the traditional unlimited structure between the screw and the bracket. It has a large range of adjustable torque parameters and solves the problems of shaft breakage, jamming, uneven rotation and difficulty in controlling torque parameters caused by excessive torque, thereby improving the rotation stability and the service life of the shaft.
