Description
Technical Field
[0001] The utility model relates to the technical field of headphone accessories, in particular to a head-wearing structure with adjustable length and radian. Background Technique
[0002] In the technical field of headphone accessories, the comfort and adaptability of the head-wearing structure have always been the focus of consumers' attention. Traditional head-wearing structures often adopt designs with fixed sizes and shapes, making it difficult for them to adapt to the head shapes and wearing needs of different users. Since there are differences in the head shapes, face shapes, and wearing habits of each person, traditional fixed head-wearing structures often cannot provide the best wearing experience for users.
[0003] In the prior art, most head-wearing structures use elastic metal sheets as the arc structure for wearing on the human head, and a telescopic buckle structure is often provided between the power amplifier board in contact with the human ear and the arc structure. Although the traditional head-wearing structure can adapt to the sizes of different people's heads, it is mainly based on the elastic arc structure. When the user's head is too large, it will be clamped tightly, and vice versa, it will be relatively loose, thus reducing the user's experience. In view of this, we propose a head-wearing structure with adjustable length and radian. Content of the Utility Model
[0004] To make up for the above deficiencies, the utility model provides a head-wearing structure with adjustable length and radian.
[0005] The technical solution of the utility model is as follows:
[0006] A head-wearing structure with adjustable length and radian, including an arc-shaped frame and vertical frames integrally formed at both ends of the arc-shaped frame. As a preferred technical solution, a cross plate is fixedly connected to the center of the top of the arc-shaped frame. Two adjusting blocks that move towards or away from each other are slidably installed in the cross plate. A first adjusting motor for driving the movement of the adjusting blocks is installed in the motor chamber of the cross plate. The bottom of the adjusting block is connected to the arc-shaped frame, and when the adjusting block moves left and right, the radian of the arc-shaped frame changes. A power amplifier board is fixedly installed at the bottom of each vertical frame. A fixed cover is fixed on the outer wall of the vertical frame, and a driving mechanism for driving the up and down movement of the power amplifier board is installed in the fixed cover. The driving mechanism includes a second adjusting motor for providing power.
[0007] As a preferred technical solution, two arc-shaped openings are symmetrically opened on the arc-shaped frame. A limit sliding groove is opened on the inner walls of both sides of the arc-shaped opening. A limit block is fixedly connected to the outer walls of both sides of the adjusting block, and the two limit blocks respectively extend into the two limit sliding grooves.
[0008] As a preferred technical solution, the limit block is cylindrical, and its outer wall is closely attached to the inner wall of the limit sliding groove.
[0009] As a preferred technical solution, a lead screw is rotatably connected in the installation groove at the bottom of the horizontal plate. The thread on the lead screw is divided into two parts with opposite directions in the middle. Two adjusting blocks are respectively threadedly connected to the two parts of the lead screw with opposite thread directions. The lead screw is coaxially fixed to the output shaft of the first adjusting motor.
[0010] As a preferred technical solution, a telescopic plate extending into the vertical frame is fixed on the top of the power amplifier board. A plurality of parallel and equally spaced flat teeth are integrally formed on the outer wall of the telescopic plate close to the fixed cover.
[0011] As a preferred technical solution, the driving mechanism further includes a mounting plate fixed in the fixed cover. A movable shaft is rotatably installed at the bottom of the mounting plate. A spiral tooth is integrally formed on the circumferential outer wall of the movable shaft. The side of the spiral tooth close to the telescopic plate meshes with the flat teeth. The movable shaft is coaxially fixed to the output shaft of the second adjusting motor.
[0012] As a preferred technical solution, during the up and down movement of the telescopic plate, the spiral teeth and the flat teeth are not completely separated.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4 , the present invention provides a technical solution:
[0023] A head-mounted structure with adjustable length and arc, including an arc-shaped frame 1 and vertical frames 4 integrally formed at both ends of the arc-shaped frame 1. A horizontal plate 2 is fixedly connected to the center of the top of the arc-shaped frame 1. Two adjustment blocks 3 that move towards or away from each other are slidably installed in the horizontal plate 2. A first adjustment motor 22 for driving the movement of the adjustment block 3 is installed in the motor compartment 21 of the horizontal plate 2. The bottom of the adjustment block 3 is connected to the arc-shaped frame 1, and the arc of the arc-shaped frame 1 changes when the adjustment block 3 moves left and right. A power amplifier board 5 is fixedly installed at the bottom of each vertical frame 4. A fixed cover 6 is fixed on the outer wall of the vertical frame 4. A driving mechanism for driving the up and down movement of the power amplifier board 5 is installed in the fixed cover 6. The driving mechanism includes a second adjustment motor 61 for providing power. Through the combined design of the arc-shaped frame 1 and the adjustment block 3, the adjustability of the arc of the arc-shaped frame 1 is realized, so as to adapt to the head shapes of different users. At the same time, the design of the vertical frame 4 in cooperation with the driving mechanism enables the power amplifier board 5 to move up and down, further improving the adjustability of the head-mounted structure. The overall design is flexible and variable, providing a personalized wearing experience, and the power is provided by the adjustment motor, which is more automated and accurate.
[0024] As a preference of this embodiment, two arc-shaped openings 10 are symmetrically opened on the arc-shaped frame 1. A limit sliding groove 11 is opened on the inner walls on both sides of the arc-shaped opening 10. A limit block 30 is fixedly connected to the outer walls on both sides of the adjustment block 3. The two limit blocks 30 are respectively inserted into the two limit sliding grooves 11. This ensures the stability and accuracy of the adjustment block 3 during the movement process. This design not only enhances the structural stability but also ensures that the adjustment block 3 can accurately change the arc of the arc-shaped frame 1 when moving.
[0025] Preferably, in this embodiment, the limiting block 30 is cylindrical, and its outer wall fits closely with the inner wall of the limiting chute 11. Such a design further improves the stability of the adjusting block 3 during movement.
[0026] Preferably, in this embodiment, a lead screw 20 is rotatably connected in the mounting groove 23 at the bottom of the cross plate 2. The thread on the lead screw 20 is divided into two parts with opposite directions in the middle. The two adjusting blocks 3 are respectively threadedly connected to the two parts of the lead screw 20 with opposite thread directions. The lead screw 20 is coaxially fixed to the output shaft of the first adjusting motor 22. Through the design of the lead screw 20 in the mounting groove 23 and in cooperation with the first adjusting motor 22, the opposite or approaching movement of the adjusting blocks 3 is realized, thereby precisely controlling the change in the curvature of the arc-shaped frame 1. The design of the thread on the lead screw 20 is unique, enabling the two adjusting blocks 3 to move in opposite directions, further enhancing the flexibility and precision of the curvature adjustment of the arc-shaped frame 1.
[0027] Preferably, in this embodiment, a telescopic plate 50 extending into the vertical frame 4 is fixed to the top of the power amplifier board 5. A plurality of parallel and equally spaced flat teeth 51 are integrally formed on the outer wall of the telescopic plate 50 close to the fixed cover 6. The design of the telescopic plate 50 and the flat teeth 51 thereon provide an accurate meshing point for the subsequent drive mechanism. The design of the parallel and equally spaced flat teeth 51 ensures the smoothness and accuracy of the transmission, providing reliable mechanical support for the up and down movement of the power amplifier board 5.
[0028] Preferably, in this embodiment, the drive mechanism further includes a mounting plate 60 fixed in the fixed cover 6. A movable shaft 62 is rotatably mounted at the bottom of the mounting plate 60. A spiral tooth 63 is integrally formed on the circumferential outer wall of the movable shaft 62. The side of the spiral tooth 63 close to the telescopic plate 50 meshes with the flat teeth 51. The movable shaft 62 is coaxially fixed to the output shaft of the second adjusting motor 61. The design of the mounting plate 60, the movable shaft 62 and the spiral tooth 63 in the drive mechanism, in cooperation with the second adjusting motor 61, realizes the accurate up and down movement of the power amplifier board 5. The meshing design of the spiral tooth 63 and the flat teeth 51 ensures the efficiency and stability of the transmission, enabling the user to accurately adjust the position of the power amplifier board 5 as needed.
[0029] Preferably, in this embodiment, during the up and down movement of the telescopic plate 50, the spiral tooth 63 and the flat teeth 51 do not completely disengage. This ensures the continuity and stability of the transmission. Such a design avoids possible jamming or tooth disengaging phenomena during the adjustment process, thereby improving the service life and user experience of the entire head-mounted structure.
[0030] When the adjustable-length and arc head-mounted structure of the present utility model is in use, first of all, the user can adjust the arc of the arc-shaped frame 1 by controlling the first adjustment motor 22 according to their own head shape and usage requirements. When the first adjustment motor 22 is started, it drives the lead screw 20 to rotate in the installation groove 23. Since the thread on the lead screw 20 is divided into two parts with opposite directions in the middle, when the lead screw 20 rotates, the two adjustment blocks 3 will move towards or away from each other along the lead screw 20 respectively.
[0031] During the movement of the adjustment block 3, the connection at its bottom will pull the arc-shaped frame 1 to deform, thereby changing the arc of the arc-shaped frame 1.
[0032] Next, the user can also adjust the up and down position of the power amplifier board 5 by controlling the second adjustment motor 61 to adapt to the ear positions and wearing comfort of different users. When the second adjustment motor 61 is started, it drives the movable shaft 62 to rotate on the mounting plate 60. The spiral teeth 63 on the movable shaft 62 rotate accordingly and engage with the flat teeth 51 on the telescopic plate 50.
[0033] Due to the meshing relationship between the spiral teeth 63 and the flat teeth 51, when the movable shaft 62 rotates, it will push the telescopic plate 50 to move up and down in the vertical frame 4, thereby driving the power amplifier board 5 to adjust its position up and down.
[0034] In summary, through the precise control of the first adjustment motor 22 and the second adjustment motor 61, the user can conveniently adjust the arc and length of the head-mounted structure to adapt to different head shapes and wearing requirements, providing a personalized wearing experience.
