Description

Technical Field

[0001] This utility model relates to the field of locking technology, and specifically to a snap-fit ​​connection structure and a sound-generating device. Background Technology

[0002] Clips are commonly used for connecting plastic structural components due to their simple structure and small footprint, and are particularly useful as a substitute for screws when high connection strength is not required. However, most existing female and male clips are of the movable type, which can easily loosen and fail when electronic devices are dropped or subjected to other accidents, causing the housing to come apart and reducing its structural reliability.

[0003] Therefore, in view of the above shortcomings, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a snap-fit ​​connection structure and a sound-generating device to at least partially solve the above-mentioned technical problems.

[0005] The first aspect of this utility model provides a snap-fit ​​connection structure, including:

[0006] A first body, which is provided with a female buckle and an elastically deformable limiting part, wherein the limiting part is disposed opposite to the female buckle to form a gap;

[0007] The second body has a flexible deformable male buckle that can be inserted into the gap and fitted with the female buckle to connect the first body and the second body.

[0008] The limiting part is used to limit the elastic deformation range of the male buckle to prevent the male buckle and the female buckle from separating.

[0009] The snap-fit ​​connection structure provided by this utility model may also have the following additional technical features:

[0010] In one specific embodiment of this utility model, the first body and the second body are fastened together vertically, and the first body and the second body are arranged opposite to each other, and are pressed from top to bottom to achieve fastening connection with the second body.

[0011] In one specific embodiment of this utility model, the first body includes a top plate and an inner edge and an outer edge formed on the outer periphery of the top plate and extending to one side of the second body. The outer edge is circumferentially disposed on the inner edge, one of the female buckle and the limiting part protrudes from the outer edge, and the other of the female buckle and the limiting part protrudes from the inner edge.

[0012] In one specific embodiment of this utility model, the female buckle protrudes from the outer edge, and the limiting part protrudes from the inner edge.

[0013] In one specific embodiment of this utility model, thinning grooves are formed at both ends of the limiting portion along the circumference of the first body.

[0014] In one specific embodiment of this utility model, along the circumference of the first body, there are two female buckles and two limiting parts, and the two female buckles are symmetrically arranged about the axial center line of the first body.

[0015] In one specific embodiment of this utility model, a notch is formed on the upper edge of the second body, and the male buckle is disposed in the notch.

[0016] In one specific embodiment of this utility model, a first guide slope is formed on the limiting portion, the first guide slope being adapted to guide the male buckle; and / or

[0017] The male buckle has a second guide slope, and the female buckle has a third guide slope that mates with the second guide slope.

[0018] In one specific embodiment of this utility model, along the circumference of the first body, the width of the female buckle is greater than the width of the limiting portion; and / or

[0019] The length of the male buckle along the height direction of the second body is less than the depth of the notch. When the second guide slope and the third guide slope are adapted to contact each other, the upper edge of the second body is inserted between the outer edge and the inner edge.

[0021] The second aspect of this utility model also provides a sound-generating device, which includes the snap-fit ​​connection structure described in any of the above-mentioned claims.

[0022] In the snap-fit ​​connection structure provided by this utility model, when the first body and the second body are snapped together, the male and female snaps fit together, and protrusions are formed on their opposite sides. Under the pressing action, the male snap undergoes elastic deformation and its protrusions intersect with the protrusions of the female snap to achieve snap-fit. In the separation direction, the male snap is not easy to remove, thereby achieving the connection function. At the same time, the limiting part set on the first body is located on the other side of the male snap and can deform together with the male snap during the pressing process to allow the male snap to be inserted. After insertion, it restricts the elastic deformation of the male snap to prevent the male snap and the female snap from separating, thereby improving the reliability of the snap-fit ​​connection structure.

[0038] Reference Figures 1-6This utility model provides a snap-fit ​​connection structure 100, including a first body 10 and a second body 20. The first body 10 is provided with a female buckle 11 and an elastically deformable limiting part 12. The limiting part 12 is disposed opposite to the female buckle 11 to form a gap. The second body 20 is provided with an elastically deformable male buckle 22. The male buckle 22 can be inserted into the gap and adapted to the female buckle 11 to fasten and connect the first body 10 and the second body 20. The limiting part 12 is used to limit the elastic deformation range of the male buckle 22 to prevent the male buckle 22 and the female buckle 11 from separating.

[0039] Specifically, when the first body 10 and the second body 20 are fastened together, the male buckle 22 and the female buckle 11 are close to each other, and protrusions are formed on their opposite sides. Under the pressing action, the male buckle 22 undergoes elastic deformation and its protrusions intersect with the protrusions of the female buckle 11 to achieve fastening. In the separation direction, the male buckle 22 is not easy to remove, thereby achieving the connection function. At the same time, the limiting part 12 provided on the first body 10 is located on the other side of the male buckle 22 and can deform together with the male buckle 22 during the pressing process to allow the male buckle 22 to be inserted. After insertion, it restricts the elastic deformation of the male buckle 22 to prevent the male buckle 22 and the female buckle 11 from separating, thereby improving the reliability of the snap-fit ​​connection structure 100.

[0040] In some embodiments, the first body 10 and the second body 20 are engaged vertically, with the first body 10 and the second body 20 positioned opposite each other, and pressed downwards to achieve a fastening connection with the second body 20. Specifically, the first body 10 and the second body 20 are positioned opposite each other, and one of them is moved in the other direction to press against the other, thereby achieving a fastening connection.

[0041] In some embodiments, the first body 10 includes a top plate and an inner edge 14 and an outer edge 13 formed on the outer periphery of the top plate and extending toward the second body 20. The outer edge 13 is circumferentially disposed around the inner edge 14. One of the female buckle 11 and the limiting portion 12 protrudes from the outer edge 13, and the other of the female buckle 11 and the limiting portion 12 protrudes from the inner edge 14.

[0042] In some embodiments, the female buckle 11 protrudes from the outer edge 13, and the limiting part 12 protrudes from the inner edge 14. Since the limiting part is elastically deformable while the female buckle 11 is not elastically deformable, when the female buckle 11 is provided on the outer edge 13 and the limiting part 12 is provided on the inner edge 14, the non-deformable capability of the female buckle 11 further improves the resistance to disassembly and damage of the snap-fit ​​connection structure 100.

[0043] In some embodiments, the height of the limiting part 12 is less than the height of the protruding position of the female buckle 11 along the pressing direction. This reduces the restriction on the free end of the male buckle 22, thereby providing more space for the deformation of the male buckle 22 without affecting its limiting effect on the male buckle 22, which is beneficial for the extrusion assembly of the first body 10 and the second body 20.

[0044] In some embodiments, thinning grooves 18 are formed at both ends of the limiting portion 12 along the circumference of the first body 10. In this embodiment, by providing thinning grooves 18 on the first body 10 at both ends of the limiting portion 12, the structural strength at the location of the thinning grooves 18 can be reduced, thereby improving its deformation capacity, thereby increasing the deformation range of the limiting portion 12, and reducing the damage to the structure of the first body 10 caused by the self-pressing snap-fit ​​connection.

[0045] In some embodiments, there are two female buckles 11 and two limiting portions 12 along the circumference of the first body 10, and the two female buckles 11 are symmetrically arranged about the axial center line of the first body 10. In this way, when the first body 10 and the second body 20 are fastened together, the connection position is also symmetrically arranged about the axial center line of the first body 10, thereby providing a reliable snap-fit ​​connection between the first body 10 and the second body 20.

[0046] Of course, in other embodiments, the number of female buckles 11 can also be 3, 4, 5, 6, etc., which can be set according to the shape and size of the first body 10.

[0047] In some embodiments, a notch 21 is formed on the upper circumferential edge of the second body 20, and a male buckle 22 is disposed within the notch 21. Thus, when the first body 10 and the second body 20 are snapped together by the male buckle 22 and the female buckle 11, the upper circumferential edge of the second body 20 will inevitably be inserted between the inner edge 14 and the outer edge 13 of the first body 10. This increases the overlap area when the first body 10 and the second body 20 are snapped together, thereby increasing the bonding strength between the two and improving their resistance to disassembly and damage.

[0048] In some embodiments, a first guide slope 16 is formed on the limiting portion 12, which is adapted to guide the male buckle 22; and / or a second guide slope 23 is formed on the male buckle 22, and a third guide slope 17 that mates with the second guide slope 23 is formed on the female buckle 11. By providing the mate guidance of the guide slopes, the fastening efficiency can be greatly improved.

[0049] In some embodiments, the width of the female buckle 11 is greater than the width of the limiting portion 12 along the circumference of the first body 10. This ensures the structural strength of the female buckle 11, improves its resistance to deformation, and thus improves its resistance to disassembly and damage. The width of the limiting portion 12 is relatively small, which improves the deformation capacity of the limiting portion 12, thereby facilitating the snap-fit ​​connection between the first body 10 and the second body 20.

[0050] In some embodiments, the length of the male buckle 22 along the height direction of the second body 20 is less than the depth of the notch 21. When the second guide slope 23 and the third guide slope 17 are in contact, the upper edge of the second body 20 is inserted between the outer edge 13 and the inner edge 14. This allows for positioning between the first body 10 and the second body 20 before the snap-fit ​​connection, which facilitates the subsequent snap-fit ​​connection operation.

[0051] In some embodiments, an observation window 15 corresponding to the female buckle 11 is provided at the connection between the top plate and the outer edge 13.

[0052] Specifically, the number of observation windows 15 corresponds one-to-one with the number of female buckles 11, and can be used to observe the engagement status of female buckles 11 and male buckles 22, thereby ensuring the reliability of engagement.

[0053] Of course, the first body 10 and the second body 20 are not limited to the top-bottom fastening relationship in this embodiment. They can also be left-right fastening, front-back fastening, diagonal fastening, etc., and the shape of the snap-fit ​​connection structure 100 is not limited to a rectangular box shape. It can also be a box or plate-shaped piece of other shapes.

[0054] The snap-fit ​​connection structure 100 provided in this embodiment can be used in electronic devices, such as headphones, remote controls, game controllers, and speakers.

[0055] Specifically, the second aspect of this utility model provides a sound-generating device, which includes a sound-generating unit and the aforementioned snap-fit ​​connection structure 100, wherein the sound-generating unit is disposed within the inner cavity of the snap-fit ​​connection structure 100. The structure of the snap-fit ​​connection structure 100 is as described in the above embodiments. Since the sound-generating device in this embodiment includes the snap-fit ​​connection structure 100 in all the above embodiments, it also has at least the beneficial effects of all the above embodiments, which will not be repeated here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
