[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0058] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0059] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0060] See appendix Figures 1 to 10 This utility model proposes a neck-hanging device, including a first main body 1, a second main body 2, and a connecting mechanism 3 connecting the first main body 1 and the second main body 2. The first main body 1 and the second main body 2 enclose a wearing space 120 for the user's neck to pass through. Fans and corresponding air outlets can be installed on the first main body 1 and the second main body 2. The connecting mechanism 3 includes a first adjustment component 3a, a second adjustment component 3b, and a connecting component 33.

[0061] The first adjusting component 3a is connected to the first main body 1, and the second adjusting component 3b is connected to the second main body 2. A connecting component 33 connects the first adjusting component 3a and the second adjusting component 3b, allowing them to swing synchronously towards each other. The connecting component 33 is preferably a gear set structure, utilizing the synchronicity of the gear meshing structure to achieve synchronous adjustment of the first main body 1 and the second main body 2. Therefore, the user can adjust either the first main body 1 or the second main body 2 individually according to their needs, while the connecting component 33 allows for synchronous adjustment of the other of the two main bodies, making adjustment more convenient and resulting in more symmetrical angles after adjustment, thus improving the user experience.

[0062] Specifically, the first adjustment component 3a includes a first movable member 31 and a first connecting member 34 rotatably connected to the first movable member 31, and the second adjustment component 3b includes a second movable member 32 and a second connecting member 35 rotatably connected to the second movable member 32.

[0063] The connecting component 33 specifically connects the first movable part 31 and the second movable part 32, allowing the first movable part 31 and the second movable part 32 to swing towards each other. The first connecting part 34 is fixedly connected to the first main body 1 by bolts, and the second connecting part 35 is fixedly connected to the second main body 2 by bolts.

[0064] Therefore, it can be seen that the first body 1 and the second body 2 have two adjustment methods. Taking the first body 1 as an example, one is that the first body 1 swings and adjusts relative to the connecting component 33 together with the first movable part 31, and the other is that the first body 1 swings and adjusts relative to the first movable part 31, so that the first body 1 and the second body 2 can be adjusted in a variety of ways.

[0065] Furthermore, the axis of swing of the first movable member 31 relative to the connecting assembly 33 is the first movable axis 310, the axis of swing of the second movable member 32 relative to the connecting assembly 33 is the second movable axis 320, the axis of rotation of the first connecting member 34 relative to the first movable member 31 is the first rotation axis 340, and the axis of rotation of the second connecting member 35 relative to the second movable member 32 is the second rotation axis 350. The first movable axis 310 and the second movable axis 320 are distributed symmetrically on the connecting assembly 33, and the structural shapes of the first movable member 31 and the second movable member 32 are mirror-symmetrically arranged according to the connecting assembly 33, such that the first rotation axis 340 and the second rotation axis 350 are symmetrically distributed on both sides of the connecting assembly 33. There is an angle between the first movable axis 310 and the first rotation axis 340, and this angle is greater than 0°, meaning that the first movable axis 310 and the first rotation axis 340 are not parallel. The second movable axis 320 and the second rotation axis 350 also have an angle, and this angle is greater than 0°, that is, the second movable axis 320 and the second rotation axis 350 are also not parallel. Preferably, the first movable axis 310 is perpendicular to the first rotation axis 340, and the second movable axis 320 is perpendicular to the second rotation axis 350.

[0066] With attachment Figure 1 The upper part shows the product's state when the neck-hanging device is laid flat. Please refer to [the documentation / reference]. Figure 3 and 4 As can be seen, at this time, the first movable axis 310 and the second movable axis 320 are horizontal lines, while the first rotation axis 340 and the second rotation axis 350 are both vertical lines. This state is referred to as the natural state below. The first main body 1 can swing up and down around the first movable axis 310, and the second main body 2 swings up and down synchronously around the second movable axis 320. This can be used to adjust the air outlet angle on the first main body 1 / second main body 2. The swinging of the first main body 1 around the first rotation axis 340 and the swinging of the second main body 2 around the second rotation axis 350 are used to adjust the width of the wearing space 120 to accommodate users with different neck thicknesses. Users can adjust the air outlet on the first main body 1 / second main body 2 to a better air outlet angle according to their own situation to meet the usage needs of different users.

[0067] Regarding the connection component 33, in some embodiments, as shown in the appendix Figures 4 to 6 As shown, the connecting assembly 33 includes a connecting base 331, a first connecting shaft 332, a second connecting shaft 333, a first gear component 334, and a second gear component 335. The first connecting shaft 332 and the second connecting shaft 333 are both rotatably mounted on the connecting base 331. The first gear component 334 is mounted on the first connecting shaft 332 and rotates synchronously with the first connecting shaft 332. The second gear component 335 is mounted on the second connecting shaft 333 and rotates synchronously with the second connecting shaft 333.

[0068] Furthermore, the first connecting shaft 332 is connected to the first movable member 31, causing the first movable member 31 to rotate synchronously with the first connecting shaft 332. The second connecting shaft 333 is connected to the second movable member 32, causing the second movable member 32 to rotate synchronously with the second connecting shaft 333. The first gear 334 and the second gear 335 are connected by a transmission mechanism, which can be directly meshed or meshed through other gear sets. Therefore, when the first movable member 31 swings relative to the connecting base 331, the second movable member 32 will necessarily swing relative to the connecting base 331 at the same time, and the rotation directions of the first connecting shaft 332 and the second connecting shaft 333 will be opposite, realizing the opposite swing of the first movable member 31 and the second movable member 32. This correspondingly drives the first main body 1 and the second main body 2 to swing synchronously in the vertical direction, realizing the synchronous adjustment of the pitch angle of the air outlets on the first main body 1 and the second main body 2.

[0069] The connecting base 331 is used to define the positions of the first connecting shaft 332 and the second connecting shaft 333, preventing the first gear component 334 and the second gear component 335 from separating from each other. In these embodiments, the axis of the first connecting shaft 332 is the aforementioned first movable axis 310, and the axis of the second connecting shaft 333 is the aforementioned second movable axis 320.

[0070] In some embodiments, as shown in the appendix Figure 5 As shown, the connecting base 331 includes a first clamping piece 3311 and a second clamping piece 3312 parallel to the first clamping piece 3311. The second clamping piece 3312 abuts against the first movable member 31 and the second movable member 32. An installation space 3300 is formed between the first clamping piece 3311 and the second clamping piece 3312. The first connecting shaft 332 penetrates the first clamping piece 3311 and the second clamping piece 3312, and the second connecting shaft 333 penetrates the first clamping piece 3311 and the second clamping piece 3312. The first gear member 334 and the second gear member 335 are both located within the installation space 3300. The first clamping piece 3311 and the second clamping piece 3312 are in close contact with the opposite sides of the first gear member 334 and the second gear member 335 to provide rotational resistance to the first connecting shaft 332 and the second connecting shaft 333. This allows the first movable member 31 and the second movable member 32 to maintain their current position after swing adjustment without external force, thus preventing them from automatically resetting.

[0071] To reduce the impact of wear on the first clamping piece 3311 and the second clamping piece 3312, please refer to the appendix. Figure 5In some embodiments, the connecting assembly 33 further includes a first spring 336, a first clamping member 337, a second spring 338, and a second clamping member 339. The first spring 336 is sleeved on the first connecting shaft 332 and abuts against the side of the first clamping piece 3311 away from the first movable member 31. The first clamping member 337 is threadedly connected to the first connecting shaft 332, and the first spring 336 is located between the first clamping member 337 and the first clamping piece 3311. The second spring 338 is sleeved on the second connecting shaft 333 and abuts against the side of the first clamping piece 3311 away from the second movable member 32, that is, the first spring 336 and the second spring 338 abut against the same side of the first clamping piece 3311. The second clamping member 339 is threadedly connected to the second connecting shaft 333, and the second spring 338 is located between the second clamping member 339 and the first clamping piece 3311.

[0072] In these embodiments, both the first clamping member 337 and the second clamping member 339 adopt a nut structure design. Twisting the first clamping member 337 and the second clamping member 339 can adjust the magnitude of the elastic force applied by the first spring member 336 and the second spring member 338 to the first clamping piece 3311, that is, adjust the ease of rotation of the first connecting shaft 332 and the second connecting shaft 333. After the first clamping piece 3311 wears out due to long-term use, the elastic force of the first spring member 336 and the second spring member 338 can maintain the first clamping piece 3311 in close contact with the first gear member 334 and the second gear member 335, maintaining the frictional resistance to the first gear member 334 and the second gear member 335.

[0073] To ensure that the first connecting shaft 332 and the first movable member 31 can rotate synchronously, and to ensure that the second connecting shaft 333 and the second movable member 32 can rotate synchronously, in some embodiments, both the first connecting shaft 332 and the second connecting shaft 333 are provided with positioning planes 3330 extending along their axial direction. The hole structures provided on the first movable member 31 and the first gear member 334 correspond to the shape design of the first connecting shaft 332, and the hole structures provided on the second movable member 32 and the second gear member 335 correspond to the shape design of the second connecting shaft 333.

[0074] In some other embodiments, the first gear 334 and the second gear 335 are not directly meshed, but are indirectly driven by other gears, achieving the same effect as in the aforementioned embodiments. For example, see attached... Figure 7In some embodiments shown, the connecting assembly 33 further includes an intermediate gear set 3310, which is mounted on the connecting base 331, and the first gear 334 and the second gear 335 mesh through the intermediate gear set 3310. To ensure that the first gear 334 and the second gear 335 rotate in opposite directions, the intermediate gear set 3310 includes at least two adapter gears 33101, which mesh sequentially. The two adapter gears 33101 mesh with the first gear 334 and the second gear 335 respectively, and the number of adapter gears 33101 is even. For example, there may be two or four adapter gears. Furthermore, the intermediate gear set 3310 in this embodiment can also be applied to larger neckband devices to increase the distance between the first body 1 and the second body 2, thus accommodating users with larger necks.

[0075] See appendix Figure 8 In some embodiments, the first movable member 31 is provided with a symmetrical first limiting inclined surface 311 and a second limiting inclined surface 312, and the second movable member 32 is provided with a symmetrical third limiting inclined surface 321 and a fourth limiting inclined surface 322. The first movable member 31 and the second movable member 32 are symmetrical structures. Therefore, the first movable member 31 and the second movable member 32 can swing towards each other until the first limiting inclined surface 311 abuts against the third limiting inclined surface 321, or the first movable member 31 and the second movable member 32 can swing towards each other until the second limiting inclined surface 312 abuts against the fourth limiting inclined surface 322, thereby limiting the amplitude of the vertical swing of the first main body 1 and the second main body 2. For example, in some embodiments, when the neck-hanging device is in its natural state, the angle between the first limiting inclined surface 311 and the third limiting inclined surface 321 is 60°, and the angle between the second limiting inclined surface 312 and the fourth limiting inclined surface 322 is also 60°. This means that the first main body 1 / the second main body 2 can swing upward by a maximum of 30° or downward by a maximum of 30°.

[0076] In some embodiments, the rotational connection structure between the first movable member 31 and the first connecting member 34 can specifically adopt a hinge structure; similarly, the rotational connection structure between the second movable member 32 and the second connecting member 35 can also specifically adopt a hinge structure. Specifically, the connecting mechanism 3 further includes a first intermediate shaft 37 and a second intermediate shaft 38. The first intermediate shaft 37 penetrates the first movable member 31 and the first connecting member 34, so that the first movable member 31 and the first connecting member 34 are both fitted on the first intermediate shaft 37 and can both rotate around the first intermediate shaft 37. The aforementioned first rotation axis 340 is the center line of the first intermediate shaft 37. The second intermediate shaft 38 penetrates the second movable member 32 and the second connecting member 35, so that the second movable member 32 and the second connecting member 35 are both fitted on the second intermediate shaft 38 and can both rotate around the second intermediate shaft 38. The aforementioned second rotation axis 350 is the center line of the second intermediate shaft 38.

[0077] Furthermore, the rotation between the first connector 34 and the first movable member 31 can be angularly limited, as can the rotation between the second connector 35 and the second movable member 32. This angular limitation is primarily used to limit the maximum opening angle of the first main body 1 and the second main body 2, that is, to maintain the basic shape of the wearing space 120. (See appendix) Figure 8 In some embodiments, a first limiting boss 341 is provided on the first connecting member 34, and a second limiting boss 313 is provided on the first movable member 31. The first connecting member 34 and the first movable member 31 can rotate relative to each other until the first limiting boss 341 abuts against the second limiting boss 313. When the first limiting boss 341 abuts against the second limiting boss 313, the first connecting member 34 cannot continue to rotate in the current rotation direction. Similarly, a third limiting boss 351 is provided on the second connecting member 35, and a fourth limiting boss 323 is provided on the second movable member 32. The second connecting member 35 and the second movable member 32 can rotate relative to each other until the third limiting boss 351 abuts against the fourth limiting boss 323. When the third limiting boss 351 abuts against the fourth limiting boss 323, the second connecting member 35 cannot continue to rotate in the current rotation direction.

[0078] Regarding the connecting component 33, in other embodiments, as shown in the appendix... Figure 10 As shown, the connecting assembly 33 includes a central shaft 3301. The first movable member 31 and the second movable member 32 are both rotatably connected to the central shaft 3301. The axis of the central shaft 3301 is the first movable axis 310 and the second movable axis 320; in other words, the first movable axis 310 and the second movable axis 320 coincide. Therefore, the first movable member 31 and the second movable member 32 swing and rotate around the central shaft 3301. It is understood that these embodiments do not have the function of synchronously swinging the first movable member 31 and the second movable member 32 relative to the central shaft 3301, but they can achieve multi-angle adjustment of the first body 1 and the second body 2. Furthermore, other clamping plates, pressing members, and spring members can be provided to achieve the aforementioned purpose of maintaining friction.

[0079] In some embodiments, as shown in the appendix Figure 2 and 3 As shown, a movable gap 121 is formed between the first main body 1 and the second main body 2, and the connecting mechanism 3 is located in the movable gap 121. To prevent the connecting mechanism 3 from being exposed, the neck-hanging device also includes a connecting soft sleeve 4, which connects the first main body 1 and the second main body 2 at the movable gap 121 to cover the connecting mechanism 3, thereby preventing the connecting mechanism 3 from being exposed.

[0080] To improve the user's grip on the four connecting points, some embodiments, see Appendix Figure 9The connecting mechanism 3 also includes a protective cover 36, which covers or partially covers the connecting component 33 to prevent poor grip due to uneven surface of the connecting component 33. A positioning post 361 can be provided on the protective cover 36, and a positioning notch 3313 can be formed on the connecting base 331. The positioning post 361 can be elastically engaged with the positioning notch 3313, ensuring that when the positioning post 361 and the positioning notch 3313 are properly aligned, the protective cover 36 correctly covers the connecting component 33 and prevents the protective cover 36 from detaching from the connecting component 33.

[0081] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
