Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and in particular to an angle adjustment mechanism and a neck-hanging device. Background Technology

[0002] Currently, neck-hanging devices on the market (such as neck fans and neck headphones) typically have a folding function for easy storage and to accommodate users with different neck sizes. Existing foldable neck-hanging devices use a connecting mechanism to link two main bodies that can swing relative to each other; these are referred to as the first body and the second body, respectively. The first and second bodies swing relative to each other to achieve angle adjustment or folding. However, for products like neck fans, the fan is mounted on both the first and second bodies. Existing connecting mechanisms usually only allow for unidirectional angle adjustment between the first and second bodies, resulting in an unsatisfactory airflow angle for some users with thicker necks after wearing the neck fan. Utility Model Content

[0003] In view of this, the present invention provides a connecting mechanism and a neck-hanging device to solve the problem of unsatisfactory angle adjustment of the neck-hanging device in the prior art.

[0004] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes:

The rotation trajectory of the first connecting member forms a first movable plane. The second locking member has its axis perpendicular to the rotation axis, and the second connecting member can rotate relative to the first rotating member about the axis of the second locking member. The rotation trajectory of the second connecting member forms a second movable plane.

[0012] In some embodiments, the first connector has a first arc-shaped groove and the second connector has a second arc-shaped groove;

The third locking member is fixedly installed on the first rotating member and passes through the first arc-shaped groove; the fourth locking member is fixedly installed on the second rotating member and passes through the second arc-shaped groove.

[0014] In some embodiments, the first rotating member includes a first rotating portion and two first clamping plates formed on the first rotating portion, with a first receiving space formed between the two first clamping plates, and the first connecting member partially movable within the first receiving space;

[0015] The second rotating member includes a second rotating part and two second clamping plates formed on the second rotating part. The second rotating part is hinged to the first rotating part, and the axis at the hinge point of the second rotating part and the first rotating part constitutes a rotation axis. The two second clamping plates form a second receiving space, and the second connecting member part is movable in the second receiving space.

[0016] In some embodiments, the two first clamping plates and the first connecting member are in a damped fit, and the two second clamping plates and the second connecting member are in a damped fit.

[0017] In some embodiments, both the first clamping plate and the second clamping plate are parallel to the axis of rotation.

[0019] This utility model also provides a neck-hanging device, characterized in that it includes a connecting mechanism according to any one of the claims, and a first body and a second body connected to the connecting mechanism.

[0020] In some embodiments, there is a movable gap between the first body and the second body, and a connecting mechanism is located at the movable gap to connect the first body and the second body;

[0021] The neck-hanging device also includes a connecting soft sleeve, which connects the first body and the second body, and the connecting soft sleeve closes the movement gap to cover the connecting mechanism.

[0022] In some embodiments, the first connector is fixedly connected to the first body by bolts, and the second connector is fixedly connected to the second body by bolts.

[0023] Implementing the embodiments of this utility model will have the following beneficial effects:

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.

[0047] 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.

[0048] 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.

[0049] See appendix Figures 1 to 8 This utility model proposes a connecting mechanism and a neck-hanging device having the connecting mechanism. The following example illustrates the neck-hanging device as a neck-hanging fan. The neck-hanging device has at least a first main body 1 and a second main body 2, in which a fan can be installed. Both the first main body 1 and the second main body 2 have air outlets. It can be understood that the first main body 1 and the second main body 2 are actually two parts of the neck-hanging fan's housing, and the first main body 1 and the second main body 2 can be symmetrical structures.

[0050] Specifically, the connecting mechanism is used to connect the first main body 1 and the second main body 2. The connecting mechanism includes a first rotating member 31, a second rotating member 32, a first connecting member 33, and a second connecting member 34. The second rotating member 32 is rotatably connected to the first rotating member 31, and the two rotate relative to each other around a rotation axis 300, that is, both the first rotating member 31 and the second rotating member 32 can adjust their angles around the rotation axis 300. The first connecting member 33 is fixedly connected to the first main body 1, and the first connecting member 33 is movably connected to the first rotating member 31. The movement trajectory of the first connecting member 33 relative to the first rotating member 31 is located on a first movable plane 301, as shown in the attached figure. Figure 4 and 6 As shown in the shaded area on the left side; the second connector 34 is fixedly connected to the second main body 2, and the second connector 34 is movably connected to the second rotating member 32. The movement trajectory of the second connector 34 relative to the second rotating member 32 is located on the second movable plane 302, as shown in the attached figure. Figure 4 and 6 The shaded area on the right side is shown. The first movable plane 301 changes position with the adjustment of the first rotating member 31, and the second movable plane 302 changes position with the adjustment of the second rotating member 32. However, the first movable plane 301 and the rotation axis 300 are always parallel or coincident, and the second movable plane 302 and the rotation axis 300 are always parallel or coincident. The first movable plane 301 and the second movable plane 302 are symmetrical about the rotation axis 300. Specifically, the first connecting member 33 is bolted to the first body 1, and the second connecting member 34 is bolted to the second body 2.

[0051] As attached Figure 1The diagram shows the natural state of some embodiments of the neck fan, where the rotation axis 300 is approximately vertical when placed horizontally. For ease of explanation, the following description uses an embodiment where the air outlet's airflow direction F is perpendicular to the rotation axis 300 in its natural state, i.e., the air outlet's airflow direction F is horizontal in its natural state. Therefore, there are two ways to adjust the angle of the first main body 1. One way is to allow the first main body 1 to rotate horizontally around the rotation axis 300 together with the first connecting member 33 and the first rotating member 31. This adjustment method is mainly used to accommodate different neck sizes of users. The other way is to allow the first main body 1 to move relative to the first rotating member 31 with the first connecting member 33. In this case, the first movable plane 301 is a vertical plane. This adjustment method is mainly used to adjust the pitch angle of the air outlet's airflow direction F, as shown in the attached diagram. Figure 2 The product states shown represent different air outlet angle states after using this adjustment method. The angle adjustment method of the second main body 2 is similar, that is, the second main body 2 can rotate horizontally around the rotation axis 300, or can move along the vertical second movable plane 302, which will not be described in detail here.

[0052] Understandably, the two angle adjustment methods mentioned above can be performed simultaneously, allowing the air outlets on the first main body 1 and the second main body 2 to be adjusted to the optimal air outlet angle according to the user's own situation.

[0053] Understandably, in some other embodiments, when the neck fan is in its natural state, the rotation axis 300 can also be horizontal. In these embodiments, the first body 1 swings vertically around the rotation axis 300. At this time, the first body 1 adjusts the pitch angle of the air outlet direction F, and the movement of the first body 1 along the first movable plane 301 is used to adapt to the neck thickness of different users. The adjustment method of the second body 2 is similar, and the same effect is achieved as in the previous embodiment.

[0054] Regarding the relative movement between the first connector 33 and the first rotating member 31, and the relative movement between the second connector 34 and the second rotating member 32, in some embodiments, see the appendix. Figure 4 and 5This is achieved through relative rotation. Specifically, the connecting mechanism also includes a first locking member 35 and a second locking member 36. The first locking member 35 penetrates the first rotating member 31 and the first connecting member 33, and the second locking member 36 penetrates the second rotating member 32 and the second connecting member 34. The axis 350 of the first locking member 35 is perpendicular to the aforementioned rotation axis 300, meaning that the first connecting member 33 can rotate relative to the first rotating member 31 about the axis 350 of the first locking member 35, and the rotation trajectory of the first connecting member 33 forms a first movable plane 301 parallel to the rotation axis 300. Similarly, the axis 360 of the second locking member 36 is also perpendicular to the rotation axis 300, meaning that the second connecting member 34 can rotate relative to the second rotating member 32 about the axis 360 of the second locking member 36, and the rotation trajectory of the second connecting member 34 forms a second movable plane 302 parallel to the rotation axis 300. Specifically, both the first locking member 35 and the second locking member 36 can adopt a bolt structure design, that is, each includes a screw with a nut and a nut threaded onto the screw.

[0055] Regarding the relative movement between the first connector 33 and the first rotating member 31, and the relative movement between the second connector 34 and the second rotating member 32, in some other embodiments, see the appendix. Figure 6 and 7 This is achieved through a combination of relative sliding and relative rotation. Specifically, the first connecting member 33 has a first arc-shaped groove 330, and the second connecting member 34 has a second arc-shaped groove 340. The connecting mechanism also includes a third locking member 37 and a fourth locking member 38. The third locking member 37 is fixedly mounted on the first rotating member 31 and passes through the first arc-shaped groove 330, allowing it to move within the groove. The fourth locking member 38 is fixedly mounted on the second rotating member 32 and passes through the second arc-shaped groove 340, allowing it to move within the groove. The third locking member 37 and the fourth locking member 38 can also be designed with bolts, meaning their structures are the same as those of the first locking member 35 and the second locking member 36 in the previous embodiment.

[0056] Specifically, the axis 370 of the third locking member 37 is perpendicular to the aforementioned rotation axis 300. The first connecting member 33 can rotate relative to the first rotating member 31 around the axis 370 of the third locking member 37, so that the rotation trajectory of the first connecting member 33 also constitutes the aforementioned first movable plane 301. Similarly, the axis 380 of the fourth locking member 38 is also perpendicular to the rotation axis 300, that is, the second connecting member 34 can rotate relative to the second rotating member 32 around the axis 380 of the fourth locking member 38, and the rotation trajectory of the second connecting member 34 can also constitute the aforementioned second movable plane 302. The first arc-shaped groove 330 designed in this embodiment is equivalent to allowing the rotation axis position of the first connecting member 33 to move, specifically with damping, thereby giving the first connecting member 33 a larger adjustment range. The design of the second arc-shaped groove 340 is similar, giving the second connecting member 34 a larger adjustment range.

[0057] Understandably, in other embodiments, the first arc-shaped groove 330 may be formed on the first rotating member 31, and the second arc-shaped groove 340 may be formed on the second rotating member 32, achieving the same technical effect as the previous embodiment.

[0058] In some embodiments, the first rotating member 31 is provided with a first receiving space 310, and the first connecting member 33 extends into the first receiving space 310, so that the first rotating member 31 is in a state of clamping the first connecting member 33, which is used to reduce the shaking of the first rotating member 31 when it moves; the second rotating member 32 is provided with a second receiving space 320, and the second connecting member 34 extends into the second receiving space 320, so that the second rotating member 32 is in a state of clamping the second connecting member 34, which is used to reduce the shaking of the second rotating member 32 when it moves and provide stability.

[0059] Specifically, the first rotating member 31 includes a first rotating portion 311 and two first clamping plates 312 integrally formed on the first rotating portion 311. The first clamping plates 312 are parallel to the first movable plane 301, and the two first clamping plates 312 form a first receiving space 310. The first connecting member 33 partially moves within the first receiving space 310. Similarly, the second rotating member 32 includes a second rotating portion 321 and two second clamping plates 322 formed on the second rotating portion 321. The second clamping plates 322 are parallel to the second movable plane 302, and the second rotating portion 321 is hinged to the first rotating portion 311. The axis at the hinge point forms the aforementioned rotation axis 300. The two second clamping plates 322 form a second receiving space 320, and the second connecting member 34 partially moves within the second receiving space 320.

[0060] When used in conjunction with the aforementioned first locking member 35 / third locking member 37, second locking member 36 / fourth locking member 38, tightening the first locking member 35 / third locking member 37 allows the two first clamping plates 312 to clamp the first connecting member 33 with greater force, which is used to adjust the external force required for swinging the first main body 1. Furthermore, a damping structure can be provided in the first accommodating space 310, which allows the first clamping plate 312 and the first connecting member 33 to move with damping, so that after the first connecting member 33 moves relative to the first rotating member 31, the first main body 1 can maintain its current state without the application of external force. Tightening the second locking member 36 / fourth locking member 38 allows the two second clamping plates 322 to clamp the second connecting member 34 with greater force, which is used to adjust the external force required for swinging the second body 2. A damping structure can be provided in the second receiving space 320, which allows the movement between the second clamping plate 322 and the second connecting member 34 to be damped, so that after the second connecting member 34 moves relative to the second rotating member 32, the second body 2 can maintain its current state without the application of external force.

[0061] Understandably, in some other embodiments, a first receiving space 310 may be formed on the first connector 33 to hold the first rotating member 31, and a second receiving space 320 may be formed on the second connector 34 to hold the second rotating member 32, achieving the same effect as the previous embodiment.

[0062] Regarding the relative movement between the first connector 33 and the first rotating member 31, and the relative movement between the second connector 34 and the second rotating member 32, in some further embodiments, see the appendix. Figure 8 This is achieved by using an arc-shaped guide groove and an arc-shaped guide block that slide relative to each other. Specifically, an arc-shaped guide groove 310a is formed on the first rotating member 31, and an arc-shaped guide block 330a that cooperates with the arc-shaped guide groove 310a is provided on the first connecting member 33. The length of the arc-shaped guide block 330a is less than the length of the arc-shaped guide groove 310a, so that the arc-shaped guide block 330a can also slide along the arc-shaped guide groove 310a, thus achieving the adjustment of the pitch angle of the air outlet direction F of the first main body 1. Similarly, an arc-shaped guide groove 310a can be formed on the second rotating member 32, and an arc-shaped guide block 330a can be provided on the second connecting member 34.

[0063] In some embodiments, the first rotating member 31 and the second rotating member 32 are axially symmetrical to each other, and the first connecting member 33 and the second connecting member 34 are also axially symmetrical to each other, which facilitates manufacturing.

[0064] To allow sufficient room for angle adjustment of the first body 1 and the second body 2, in some embodiments, see Appendix Figure 1 and 3There is an active gap 120 between the first body 1 and the second body 2. The connecting mechanism connects the first body 1 and the second body 2 at the active gap 120. The neck hanging device also includes a connecting soft sleeve 4. The connecting soft sleeve 4 can be a soft material such as silicone or rubber. The connecting soft sleeve 4 connects the first body 1 and the second body 2, and the connecting soft sleeve 4 closes the active gap 120 to cover the connecting mechanism.

[0065] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments.
