Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of snap fasteners, and in particular, to a snap-fastening installation structure and an electronic device. Background Art

[0002] A snap fastener is a structure for the embedded connection or overall locking of one part to another part, and is usually used for the connection of plastic parts. It has the advantages of simple structure and convenient loading and unloading. A component with a snap fastener can be called a snap-fastening installation structure. The snap-fastening installation structure is widely used in multiple fields such as consumption and industry, for example, the connection of automotive interior parts, the connection of electronic devices, etc. However, snap fasteners are usually made of plastic materials, and have disadvantages such as short fatigue life, low connection strength (or can be called mating strength), and limited number of detachable times, resulting in the snap-fastening installation structure being prone to unlocking when subjected to impact.

[0003] Therefore, how to improve the reliability of the snap-fastening installation structure is a key issue that those skilled in the art have been continuously researching. Utility Model Content

[0004] The embodiments of the present application provide a snap-fastening installation structure and an electronic device, and the main purpose is to improve the reliability of the snap-fastening installation structure.

[0005] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the embodiments of the present application provide a snap-fastening installation structure, and the snap-fastening installation structure includes a first structural member and a second structural member. The first structural member includes a first mating surface, and the first mating surface is uneven, having a first convex portion and a first concave portion. The second structural member includes a second mating surface, and the second mating surface is uneven, having a second convex portion and a second concave portion. In the state where the first structural member and the second structural member are snap-connected, the first mating surface and the second mating surface face each other. In the state where the first structural member and the second structural member are snap-connected, the top end of the first convex portion of the first mating surface contacts the second concave portion of the second mating surface, and there is a gap between the first convex portion and the second concave portion. And / or, the top end of the second convex portion of the second mating surface contacts the first concave portion of the first mating surface, and there is a gap between the second convex portion and the first concave portion. When the snap-fastening installation structure is subjected to impact, the first convex portion of the first mating surface and the second concave portion of the second mating surface are mutually limited, and / or, the second convex portion of the second mating surface and the first concave portion of the first mating surface are mutually limited, which can help to strengthen the limiting and locking between the first mating surface and the second mating surface, and then improve the impact resistance of the snap-fastening installation structure.

[0007] The snap-in mounting structure provided by the embodiments of the first aspect is as follows: First, the first mating surface and the second mating surface are set to be uneven. The first convex portion of the first mating surface contacts the second concave portion of the second mating surface, and the second convex portion of the second mating surface contacts the second concave portion of the second mating surface. The concave-convex fit between the first mating surface and the second mating surface can be utilized to improve the connection strength of the snap and the impact resistance of the snap-in mounting structure. Second, since there is a gap between the top end of the convex portion (including the first convex portion and the second convex portion) and the concave portion (including the first concave portion and the second concave portion) when they contact, it provides a buffer space for the movement of the convex portion within the concave portion. This helps the convex portion to vibrate and absorb energy within the concave portion when the snap-in mounting structure is impacted, making it difficult for the snap to become detached. Thus, it further improves the connection strength of the snap, avoids the snap from becoming detached when the snap-in mounting structure is impacted, and enhances the reliability of the snap-in mounting structure.

[0008] Combined with the first aspect, in a possible implementation, the first convex portion includes a first inclined surface. When the first structural member and the second structural member are snap-fitted and connected, there is a gap between the first inclined surface and the second concave portion. Alternatively, the second convex portion includes a second inclined surface. When the first structural member and the second structural member are snap-fitted and connected, there is a gap between the second inclined surface and the first convex portion. Thus, by using the inclined surface of the first convex portion or the second convex portion, it helps to achieve the gap between the convex portion and the concave portion.

[0009] Combined with the first aspect, in a possible implementation, along the direction in which the first convex portion protrudes, the cross-sectional shape of the first convex portion includes a triangle. And / or, along the direction in which the second concave portion depresses, the cross-sectional shape of the second concave portion includes a triangle. Thus, by using the triangular cross-sectional shape of the convex portion, the convex portion can be in the shape of a triangular prism, which facilitates the setting of the shapes of the first convex portion and the second concave portion, and enables there to be a gap when the top end of the convex portion contacts the concave portion.

[0010] Combined with the first aspect, in a possible implementation, along the direction in which the first convex portion protrudes, the cross-sectional shape of the first convex portion includes a triangle. Along the direction in which the second concave portion depresses, the cross-sectional shape of the second concave portion includes a triangle. The apex angle of the cross-sectional shape of the first convex portion is not equal to the apex angle of the cross-sectional shape of the second concave portion. Thus, the apex angle of the convex portion can contact the base angle of the concave portion, thereby achieving line-line fit between the convex portion and the concave portion, or the apex angle of the convex portion can contact the surface of the concave portion, thereby achieving line-surface fit between the convex portion and the concave portion. Both can help, when the snap-in mounting structure is impacted, to cause the contact relationship between the first mating surface and the second mating surface to be crushed, achieving the effect of bite energy absorption, and further ensuring the stable fit of the snap-in mounting structure.

[0011] In combination with the first aspect, in a possible implementation manner, along the direction in which the first convex portion protrudes, the cross-sectional shape of the first convex portion includes a trapezoid. And / or, along the direction in which the second concave portion depresses, the cross-sectional shape of the second concave portion includes a trapezoid. Among them, the inclined surface of the trapezoid helps to form a gap between the convex portion and the concave portion.

[0012] In combination with the first aspect, in a possible implementation manner, the first mating surface includes a plurality of first convex portions. The second mating surface includes a plurality of second concave portions. Thus, by increasing the number of the convex portions and the concave portions, the locking between the first mating surface and the second mating surface can be strengthened, and the impact resistance of the snap-fit mounting structure can be improved.

[0013] In combination with the first aspect, in a possible implementation manner, the plurality of first convex portions are arranged along a first direction and extend along a second direction. The plurality of second concave portions are arranged along a third direction and extend along a fourth direction. In this implementation manner, the first convex portions of the first mating surface are arranged in a strip shape, and the second concave portions of the second mating surface are arranged in a strip shape. Through the arrangement of the concave portions or the convex portions, the concave-convex fit between the first mating surface and the second mating surface can also be realized, and the connection strength of the snap can be improved.

[0014] In combination with the first aspect, in a possible implementation manner, during the process of the snap-fit connection between the first structural member and the second structural member, the first mating surface moves along a direction parallel to the second direction, or the second mating surface moves along a direction parallel to the fourth direction. In this implementation manner, the extending direction of the concave portion or the convex portion is parallel to the direction in which the first mating surface and the second mating surface move during the snap-in or snap-out of the snap, so that the snap can be snapped in or out along the extending direction of the concave portion or the convex portion, enhancing the easy assembly and disassembly of the snap-fit mounting structure.

[0015] In combination with the first aspect, in a possible implementation manner, in the state where the first structural member and the second structural member are snap-fit connected, the first direction is parallel to the third direction, and the second direction is parallel to the fourth direction. Thus, the entirety of the first mating surface can be parallel to the entirety of the first mating surface, which helps with the easy assembly and disassembly of the snap-fit mounting structure.

[0016] In combination with the first aspect, in a possible implementation manner, in the state where the first structural member and the second structural member are snap-fit connected, the first direction is parallel to the third direction, and the second direction is not parallel to the fourth direction. As a result, the entirety of the first mating surface can be non-parallel to the entirety of the second mating surface, reducing the contact area between the entirety of the first mating surface and the entirety of the second mating surface, which helps, when the snap-fit mounting structure is impacted, for the contact relationship between the first mating surface and the second mating surface to experience crushing, playing a role in energy absorption and further improving the impact resistance of the snap-fit mounting structure.

[0017] In combination with the first aspect, in a possible implementation, a plurality of first protrusions are arranged in an array, and a plurality of second recesses are arranged in an array, thereby achieving concave-convex matching by using the plurality of protrusions and recesses arranged in an array, and also helping to improve the connection strength of the buckle.

[0018] In combination with the first aspect, in a possible implementation, along the direction in which the first protrusions protrude, the sizes of the plurality of first protrusions are not completely the same. And / or, along the direction in which the second concave portions are sunken, the sizes of the plurality of second concave portions are not completely the same. Thus, by reducing the need for standardized dimensions, the first mating surface and the second mating surface are easier to manufacture, and the size differentiation design of the protrusions or concave portions can be used to enhance the ease of assembly or impact resistance of the snap-on mounting structure.

[0019] In combination with the first aspect, in a possible implementation, the first convex portion or the second convex portion can be deformed under stress. In this implementation, the deformation characteristics of the convex portion can be used to partially crush the first convex portion or the second convex portion when subjected to stress, and the deformation of the first convex portion or the second convex portion is used to absorb impact energy, so that the first convex portion or the second convex portion plays a role of biting and absorbing energy, further ensuring stable matching of the snap-on installation structure.

[0020] In combination with the first aspect, in a possible implementation, the first structural member is connected to the antenna structural member, and the second structural member is connected to the host structural member. The antenna structural member is connected to the host structural member by snapping the first structural member and the second structural member together. Thus, the snap-on mounting structure can be applied to electronic devices that require antennas to be connected to a host, such as routers, set-top boxes, etc., and the first structural member and the second structural member are snap-on locked to complete the connection between the antenna structural member and the host structural member.

[0021] In combination with the first aspect, in a possible implementation, when the antenna structure is subjected to a force along the fifth direction, the top end of the first protrusion is deformed or moved in the second recess. And / or, the top end of the second protrusion is deformed or moved in the first recess. The fifth direction is parallel to the direction of the first mating surface toward the second mating surface. Thus, the first mating surface and the second mating surface are locked by utilizing the mutual limiting effect between the protrusion and the recess. In addition, the deformation of the first protrusion or the second protrusion can also play a role in biting and absorbing energy, thereby improving the impact resistance of the buckle, thereby being able to curb the tendency of the antenna structure to separate from the host structure from multiple directions, and improving the connection performance between the antenna structure and the host structure.

[0022] In a second aspect, an embodiment of the present application provides an electronic device, the electronic device comprising a first component, a second component and the snap-on mounting structure in the above embodiment. The first component is connected to the first structural member, and the second component is connected to the second structural member.

[0023] In combination with the second aspect, in a possible implementation, the electronic device includes a router or a set-top box. The first component includes an antenna structure, and the second component includes a host structure.

[0024] For the technical effects brought about by the design method in the second aspect, reference can be made to the technical effects brought about by different design methods in the first aspect, which will not be elaborated here. Description of the Drawings

[0039] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present application belong to the scope of protection of the present application.

[0040] Among them, in the description of the embodiments of the present application, unless otherwise specified, "a plurality of" means two or more than two. "At least one (piece)" or its similar expression refers to any combination of these items, including any combination of a single item (piece) or plural items (pieces). For example, at least one (piece) of a, b, and c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple. "A and / or b" includes the following three combinations: only a, only b, and the combination of a and b.

[0041] In addition, for the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. Those skilled in the art can understand that the terms "first" and "second" do not limit the quantity and execution order, and the terms "first" and "second" do not necessarily mean different. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific way for easy understanding.

[0042] When describing some embodiments, the expression of "connection" and its derivatives is used. The term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium. In addition, the use of "based on" means open and inclusive, because a process, step, calculation, or other action "based on" one or more of the said conditions or values can, in practice, be based on additional conditions or values beyond the said ones.

[0043] As used herein, "parallel", "perpendicular", and "equal" include the stated cases and cases similar to the stated cases, where the range of such similar cases is within an acceptable deviation range, and the acceptable deviation range is determined by a person of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, that the difference between the two equal values is less than or equal to 5% of either one of them.

[0044] In the embodiments of the present application, "upper", "lower", "left", and "right" are not defined only in terms of the orientation of the components shown in the relative drawings. It should be understood that these directional terms can be relative concepts, and they are used for relative description and clarification, and they can change accordingly with the change of the orientation of the components shown in the drawings. In the drawings, for clarity, the thickness of the layers and regions is exaggerated, and the dimensional proportional relationships between the various parts in the illustration do not reflect the actual dimensional proportional relationships. Therefore, variations in the shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances can be envisioned. Therefore, the exemplary embodiments should not be construed as being limited to the shapes of the regions shown in the present application, but include shape deviations caused by, for example, manufacturing. For example, an etched region shown as a rectangle will generally have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, and are not intended to limit the scope of the exemplary embodiments.

[0045] In addition, the architectures and scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. As is known to a person of ordinary skill in the art, with the evolution of architectures and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0046] Embodiments of the present application provide an electronic device, which can be applied to various communication systems or communication protocols, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access Wireless (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), etc. The above-mentioned electronic devices include, for example, consumer products, home products, in-vehicle products, wearable products, financial terminal products, communication products, and intelligent detection products. Exemplarily, the electronic device may include, but is not limited to, a router, a switch, headphones, a microphone, a mobile phone, a tablet (pad), a smart wearable product (e.g., a smart watch, a smart bracelet), an extended reality (XR) device, an inertial navigation device, a supplemental inflatable restraint system (SRS) device for automobiles, a smart door lock, a stethoscope, a helmet, a handle, a fluid manometer, etc. The above-mentioned XR device is, for example, a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device. Embodiments of the present application do not limit the specific form of the above devices.

[0047] Embodiments of the present application also provide a non-electronic device. The specific types of non-electronic devices include, but are not limited to, household furniture, agricultural equipment, industrial equipment, transportation vehicles, medical equipment, etc. Taking household furniture as an example, the non-electronic device may be a luggage. Taking transportation vehicles as an example, the non-electronic device may be a bicycle.

[0048] For many products, whether they are electronic devices or non - electronic devices, etc., the need for miniaturization may be involved in their application fields, which often requires continuous conception and improvement of the minimalist architecture of the products to be realized. Moreover, the conception of the minimalist architecture of the products is of great significance for design efficiency, strengthening manufacturability, and improving product performance. Simplifying the stacking and mating relationship of structural parts simplifies the dimension chain, the product disassembly plan, and the manufacturing and assembly processes. It is a powerful way to reduce various costs such as supply, materials, and production, and is also an effective way to clarify the product design idea and enhance product power. With the increasing demand for architecture extreme simplification day by day, all fields of software and hardware are facing new challenges, which means achieving all - round new upgrades with the shortest path. In terms of structure, even the design of the buckle needs to be re - considered.

[0049] Figure 1 FIG. is a schematic structural diagram of an electronic device provided by an embodiment of the present application.

[0050] Please refer to Figure 1 , the electronic device 1000 can be a router. The router includes an antenna and a host. Among them, the antenna includes a male - end buckle structural member 1 and an antenna structural member 101, and the antenna structural member 101 is connected to the male - end buckle structural member 1. The host includes a female - end buckle structural member 2 and a host structural member 201, and the host structural member 201 is connected to the female - end buckle structural member 2.

[0051] In the above - mentioned electronic device 1000, the connection between the antenna and the host can be realized by forming a buckle fit between the male - end buckle structural member 1 and the female - end buckle structural member 2. Among them, since the male - end buckle structural member 1 and the female - end buckle structural member 2 cannot be seen from the outside of the router after the antenna and the host are assembled, they are Figure 1 schematically shown by dotted lines in

[0052] Taking the above - mentioned electronic device 1000 being a router as an example, to realize the miniaturization of the router, even the buckle structure in the router needs to further reduce the occupied assembly space. Or rather, under the condition of reducing the occupied space, ensure the reliability of the connection between the antenna and the host.

[0053] Figures 2A - 2D FIG. is some schematic structural diagrams of the male - end buckle structural member provided by an embodiment of the present application.

[0054] Based on the above considerations, some snap - in mounting structures are provided in embodiments of the present application. Please refer to Figures 2A - 2D , these snap - in mounting structures include a male - end buckle structural member 1 and a female - end buckle structural member 2 ( Figures 2A - 2D not shown).

[0055] Please refer to Figure 2A, an embodiment of the present application provides a male end snap structure member 1. The type of snap used in the snap - type installation structure to which the male end snap structure member 1 is applied is a straight - arm snap. Among them, the male end snap structure member 1 includes a male end mating surface 11 and an elastic part 12, and the elastic part 12 is a straight arm.

[0056] Please refer to Figure 2B , an embodiment of the present application provides a male end snap structure member 1. The type of snap used in the snap - type installation structure to which the male end snap structure member 1 is applied is an L - shaped snap. Among them, the male end snap structure member 1 includes a male end mating surface 11 and an elastic part 12, and the elastic part 12 is an L - shaped arm.

[0057] Please refer to Figure 2C , an embodiment of the present application provides a male end snap structure member 1. The type of snap used in the snap - type installation structure to which the male end snap structure member 1 is applied is a circumferential snap. Among them, the male end snap structure member 1 includes a male end mating surface 11. It can be understood that in the snap - type installation structure including a circumferential snap, the male end snap structure member 1 may not be provided with an elastic part, and the elastic part is provided on the female end snap structure member to play a role in snap - fit connection.

[0058] Please refer to Figure 2D , an embodiment of the present application provides a male end snap structure member 1. The type of snap used in the snap - type installation structure to which the male end snap structure member 1 is applied is a U - shaped snap. Among them, the male end snap structure member 1 includes a male end mating surface 11 and an elastic part 12, and the elastic part 12 is a U - shaped arm.

[0059] Please refer to Figure 1 , in the snap - type installation structure proposed in the above - mentioned embodiment, different types of male end snap structure members 1 cooperate with female end snap structure members 2 to achieve snap - fit assembly in different forms and different stacking spaces. Although Figures 2A - 2D the snap types in the shown snap - type installation structure are different, the mating surfaces of the snaps (referring to the male end mating surface 11) are all flat surfaces. The connection strength of the snaps in these snap - type installation structures is mainly affected by the strength of the elastic arms and the snap - fit amount of the snaps.

[0060] Figure 3A is a side view of a snap - type installation structure 100 including a straight - arm snap. Figure 3B is a front view of a snap - type installation structure 100 including a straight - arm snap. Figures 3A - 3B shows the mating relationship between the male end snap structure member 1 and the female end snap structure member 2.

[0061] Please refer to Figures 3A - 3B, taking the snap - on mounting structure 100 including a straight - arm snap as an example for illustration, the snap - on mounting structure 100 includes a male - end snap structure member 1 and a female - end snap structure member 2, and the male - end mating surface 11 and the female - end mating surface 21 are opposite and both are flat surfaces.

[0062] The fifth direction X can be the movement direction of the male - end snap structure member 1 relative to the female - end snap structure member 2 when the snap is disengaged. If the snap - on mounting structure 100 is impacted, taking the female - end snap structure member 2 as a reference, the male - end snap structure member 1 will move along the fifth direction X. The impact force acts on the male - end snap structure member 1 and the female - end snap structure member 2, which will cause a tendency of relative detachment between the male - end snap structure member 1 and the female - end snap structure.

[0063] For the different types of snap - on mounting structures 100 proposed in the above - mentioned embodiments, generally, the snap - fit can be strengthened through three paths: increasing the snap - fit amount (or the snap - fit depth between the male - end mating surface 11 and the female - end mating surface 21), shortening the length of the elastic arm, and increasing the thickness or width of the elastic arm. However, to ensure the easy assembly, disassembly, and reliability of the snap, the length, thickness, or width of the snap elastic arm cannot be adjusted randomly for strengthening the snap - fit. Then, only by increasing the snap - fit amount can the snap - fit be strengthened.

[0064] Figure 3C Another side view of the snap - on mounting structure 100 including a straight - arm snap.

[0065] Please refer to Figure 3C , which schematically shows the assembly space of the male - end snap structure member 1 and the virtual area 1' that the male - end snap structure member 1 passes through during the assembly or disengagement movement process. Among them, the shaded part can be other devices in the product stack or a part of the structure of the female - end snap structure member 2. The structure drawn with a dotted line shows the virtual area 1' that the male - end snap structure member passes through during the movement process.

[0066] In one example, for a snap with the length L of the elastic part 12 being 7 mm, the snap - fit amount M of the snap being 1 mm, and the thickness N of the elastic part 12 being 1 mm, the backward movement amount W for the assembly or disassembly of the male - end snap structure member 1 is 1.38 mm. Then, the snap needs to occupy a device stack space with a width of 1.38 mm. If the length L of the elastic part 12 and the snap - fit amount M of the snap are further increased, a larger device stack space needs to be occupied. Therefore, when the devices of the product are extremely stacked, strengthening the elastic part 12 and increasing the snap - fit amount M of the snap will both have an adverse impact on the miniaturization of the product structure.

[0067] Further refer to Figure 3CFor analysis, when using the same materials, improving the connection strength and reliability of the buckle of the snap - fit mounting structure 100 depends on increasing the snap - fit amount M and strengthening the elastic part 12. However, increasing the snap - fit amount M of the buckle and strengthening the elastic part 12 will both increase the backward avoidance space during the snap - fit movement or disassembly movement of the buckle, thus occupying more of the stacking space of the internal components of the product and affecting the ultimate stacking effect of the internal components of the product. Moreover, strengthening the elastic part 12, that is, increasing the overall rigidity of the elastic part 12, will also lead to a decrease in the ability of the elastic part 12 to undergo plastic deformation. This will not only reduce the ease of assembly and disassembly of the buckle, but also make the elastic part 12 more likely to have local fractures when the snap - fit mounting structure 100 is impacted due to the decrease in elasticity, which will instead have an adverse effect on the reliability of the product.

[0068] Therefore, when the internal components of the product need to be stacked to the extreme, if the stacking space cannot be increased and the assemblability of the snap - fit mounting structure needs to be ensured, the design of the above - mentioned snap - fit mounting structure 100 will be strongly restricted and the assembly reliability cannot be guaranteed.

[0069] Obviously, the current buckle design is difficult to balance the reliability of the snap - fit mounting structure and the miniaturization requirements of the product.

[0070] Based on this, the embodiments of the present application provide a snap - fit mounting structure. Figures 4A - 4C Some snap - fit mounting structures provided by the embodiments of the present application are shown. Among them, Figure 4A The released state of the snap - fit mounting structure provided by the embodiments of the present application is shown.

[0071] Please refer to Figure 4A , the snap - fit mounting structure 100 includes a first structural member 3 and a second structural member 4.

[0072] In the embodiments of the present application, the first structural member 3 and the second structural member 4 can be snap - fit connected in the form of a buckle and can also be released by disassembling the buckle.

[0073] In some examples, the first structural member 3 can be a positioning member, and the second structural member 4 can be a fastening member. In some other examples, the first structural member 3 can be a fastening member, and the second structural member 4 can be a positioning member. Among them, the fastening member can be provided with elastic arms.

[0074] In some examples, the first structural member 3 can include a female - end buckle, and the second structural member 4 can include a male - end buckle. In some other examples, the first structural member 3 can include a male - end buckle, and the second structural member 4 can include a female - end buckle. Among them, either the male - end buckle or the female - end buckle can be provided with elastic arms.

[0075] Please refer to Figure 4A, the first structural member 3 includes a first mating surface 31, the first mating surface 31 is uneven, and the first mating surface 31 has a first convex portion 311 and a first concave portion 312.

[0076] Please refer to Figure 4A , the second structural member 4 includes a second mating surface 41, the second mating surface 41 is uneven, and the second mating surface 41 has a second convex portion 411 and a second concave portion 412.

[0077] In the embodiment of the present application, the first convex portion 311 may refer to a convex structure with respect to the plane where the bottom surface of the first convex portion 311 is located, and the second convex portion 411 may refer to a convex structure with respect to the plane where the bottom surface of the second convex portion 411 is located. The first convex portion 311 and the second convex portion 411 may be collectively referred to as convex portions.

[0078] In the embodiment of the present application, the first concave portion 312 may refer to a concave structure with respect to the plane where the bottom surface of the first concave portion 312 is located, and the second concave portion 412 may refer to a concave structure with respect to the plane where the bottom surface of the second concave portion 412 is located. The first concave portion 312 and the second concave portion 412 may be collectively referred to as concave portions.

[0079] In some alternative embodiments, the bottom surface of the first convex portion 311 may coincide with the plane where the top end of the first concave portion 312 is located, and the top end of the first convex portion 311 may coincide with the plane where the bottom surface of the first concave portion 312 is located.

[0080] In the embodiment of the present application, the top end of the first convex portion 311 may refer to the end of the first convex portion 311 facing the second concave portion 412, and the top end of the second convex portion 411 may refer to the end of the second convex portion 411 facing the first concave portion 312.

[0081] In some alternative embodiments, the bottom surface of the second convex portion 411 may coincide with the plane where the top end of the second concave portion 412 is located, and the bottom surface of the second concave portion 412 may coincide with the plane where the top end of the second convex portion 411 is located.

[0082] Please refer to Figure 4A , in some alternative embodiments, the first convex portion 311 and the first concave portion 312 may be alternately arranged, and the side surface of the first convex portion 311 may coincide with the side surface of the first concave portion 312.

[0083] Alternatively, the second convex portion 411 and the second concave portion 412 may be alternately arranged, and the side surface of the second convex portion 411 may coincide with the side surface of the second concave portion 412.

[0084] In some alternative embodiments, the material of the first structural member 3 or the second structural member 4 may include but is not limited to plastic. The second mating surface 31 of the first structural member 3 or the second mating surface 41 of the second structural member 4 may be obtained by draft forming.

[0085] Please refer to Figure 4A , in some alternative embodiments, the formation of the second mating surface 41 can be achieved by tilting the mating surface that should originally be perpendicular to the retraction direction of the buckle to a certain extent, such that an acute angle is formed between the entirety of the second mating surface 41 and the entirety of the first mating surface 31, resulting in a line-plane contact. Or, the plane parallel to the first direction Y and the second direction Z and the plane parallel to the third direction U and the fourth direction V are not parallel.

[0086] Unless otherwise specified, when expressing positional relationships, the first mating surface 31 or the second mating surface 41 can be understood as the plane on which the convex or concave portions are arranged or extended. Exemplarily, the first mating surface 31 or the entirety of the first mating surface 31 in the embodiments of the present application can be a plane parallel to the first direction Y and the second direction Z. The second mating surface 41 or the entirety of the second mating surface 41 can be a plane parallel to the third direction U and the fourth direction V.

[0087] Figure 4B Fig. 10 shows the engaged connection state of the snap-fit mounting structure 100 provided by the embodiments of the present application.

[0088] Please refer to Figure 4B , in the state where the first structural member 3 is snap-fitted to the second structural member 4, the first mating surface 31 faces the second mating surface 41, and the first recess 312 of the first mating surface 31 contacts the second protrusion 411 of the second mating surface 41, and the first protrusion of the first mating surface contacts the second recess of the second mating surface, forming a snap for the snap-fit connection.

[0089] In the embodiments of the present application, the first mating surface 31 facing the second mating surface 41 can mean that the first mating surface 31 and the second mating surface 41 are generally facing each other. Specifically, the first mating surface 31 and the second mating surface 41 can be parallel or non-parallel (or can intersect). Among them, if the first mating surface 31 and the second mating surface 41 are non-parallel, the included angle between the two can be within a certain angular range to ensure the connection effect of the snap.

[0090] In some alternative embodiments, the first mating surface 31 faces the second mating surface 41, and the included angle between the first mating surface 31 and the second mating surface 41 can be less than or equal to 30°.

[0091] For example, the included angle between the first mating surface 31 and the second mating surface 41 can include but is not limited to 0°, 5°, 10°, 15°, 30°.

[0092] Figure 4C Fig. 28 is a front view of the snap-fit mounting structure 100 provided by the embodiments of the present application in the engaged connection state.

[0093] Please refer toFigure 4C When the snap - type installation structure is impacted, with the female - end snap - structure member 2 as a reference, the male - end snap - structure member 1 may move. The first recess 312 of the first mating surface 31 and the second protrusion 411 of the second mating surface 41 limit each other, and the first protrusion 311 of the first mating surface 31 and the second recess 412 of the second mating surface 41 limit each other, which can help strengthen the locking between the first mating surface 31 and the second mating surface 41, thereby improving the impact resistance of the snap - type installation structure 100.

[0094] Therefore, the above - mentioned embodiments can improve the connection strength of the snap and the impact resistance of the snap - type installation structure, prevent the snap - type installation structure from being disengaged when impacted, and improve the reliability of the snap - type installation structure.

[0095] The snap - type installation structure 100 in the embodiments of the present application can be applied to various products.

[0096] For products with miniaturization requirements, when the stacking space of the product is extremely limited, if we want to strengthen the connection strength of the snap, we need to increase the snap - fitting amount of the snap, thus requiring an increase in the space left for the snap to retreat during assembly or disassembly, which has an adverse impact on the miniaturization of the stacking structure.

[0097] However, the snap - type installation structure 100 in the above - mentioned embodiments introduces the uneven first mating surface 31 and second mating surface 41 to achieve the snap - fitting connection. Even if the snap - fitting amount of the snap is reduced, the reliability of the snap - type installation structure can be ensured, thereby reducing the waste of the retreat space during snap assembly, being beneficial to the miniaturization of the product and realizing the extreme stacking of internal components of the product, taking into account both the reliability of the snap - type installation structure and the miniaturization requirements of the product.

[0098] For products with requirements for easy assembly or disassembly, if we want to improve the connection strength of the snap by strengthening the rigidity of the elastic arm of the snap, such as shortening the elastic arm or increasing the thickness of the elastic arm, the assembly difficulty and disassembly difficulty of the product will increase significantly, weakening the maintainability of the product.

[0099] However, for the snap - type installation structure 100 with the uneven first mating surface 31 and second mating surface 41 in the above - mentioned embodiments, even if the rigidity of the elastic arm is not strengthened, the reliability of the snap - type installation structure can be ensured, thereby retaining the easy assembly or disassembly of the product, making the product easy to manufacture and simple to repair.

[0100] Figure 4D It is another front view of the snap - type installation structure 100 provided by the embodiments of the present application in the snap - fitting connection state.

[0101] Please refer to Figure 4D, in some further alternative embodiments, in a state where the first structural member 3 is snap-fitted to the second structural member 4, the top end of the first protrusion 311 of the first mating surface 31 contacts the second recess 412 of the second mating surface 41, and there is a gap between the first protrusion 311 and the second recess 412.

[0102] Through the above embodiments, the contact between the top end of the first protrusion 311 and the second recess 412 with a gap therebetween provides a buffer space for the movement of the first protrusion 311 within the second recess 412. This helps the first protrusion 311 to absorb energy by vibrating within the second recess 412 when the snap-fit mounting structure is impacted, making it difficult for the snap to become disengaged. Thus, the connection strength of the snap is further enhanced, preventing the snap-fit mounting structure 100 from becoming disengaged when impacted and improving the reliability of the snap-fit mounting structure 100.

[0103] In some further alternative embodiments, in a state where the first structural member 3 is snap-fitted to the second structural member 4, the top end of the second protrusion 411 of the second mating surface 41 contacts the first recess 312 of the first mating surface 31, and there is a gap between the second protrusion 411 and the first recess 312.

[0104] Through the above embodiments, the contact between the top end of the second protrusion 411 and the first recess 312 with a gap therebetween provides a buffer space for the movement of the second protrusion 411 within the first recess 312. This helps the second protrusion 411 to absorb energy by vibrating within the first recess 312 when the snap-fit mounting structure 100 is impacted, making it difficult for the snap to become disengaged. Thus, the connection strength of the snap is further enhanced, preventing the snap-fit mounting structure 100 from becoming disengaged when impacted and improving the reliability of the snap-fit mounting structure 100.

[0105] In some further alternative embodiments, in a state where the first structural member 3 is snap-fitted to the second structural member 4, the top end of the first protrusion 311 of the first mating surface 31 contacts the second recess 412 of the second mating surface 41, and there is a gap between the first protrusion 311 and the second recess 412. Also, the top end of the second protrusion 411 of the second mating surface 41 contacts the first recess 312 of the first mating surface 31, and there is a gap between the second protrusion 411 and the first recess 312. Thus, the combined effects of the cooperation between the first protrusion 311 and the second recess 412 and the cooperation between the second protrusion 411 and the first recess 312 can be achieved, further improving the reliability of the snap-fit mounting structure.

[0106] Please refer to Figure 4D , in some alternative embodiments, the first protrusion 311 includes a first inclined surface 3111, and there is a gap between the first inclined surface 3111 and the second recess in a state where the first structural member 3 is snap-fitted to the second structural member 4.

[0107] In the embodiments of the present application, the inclined surface may refer to the slope of a certain surface relative to the overall surface of the object on which the surface is located. Exemplarily, the extension direction of the first inclined surface 3111 may not be parallel to the first direction Y and the second direction Z.

[0108] In some other alternative embodiments, the second protrusion 411 includes a second inclined surface 4111. In the state where the first structural member 3 is engaged with the second structural member 4, there is a gap between the second inclined surface 4111 and the first protrusion.

[0109] Exemplarily, the second inclined surface 4111 may intersect with the third direction U and the fourth direction V.

[0110] Through the above embodiments, by using the inclined surfaces of the first protrusion or the second protrusion, it is helpful to realize the gap between the protrusion and the recess.

[0111] In some alternative embodiments, the first protrusion 311 or the second protrusion 411 can be deformed under force. Thus, the first protrusion 311 or the second protrusion 411 can be locally crushed when under force. This process can utilize the deformation of the first protrusion 311 or the second protrusion 411 to absorb impact energy, enabling the first protrusion 311 or the second protrusion 411 to play a role in engaging and absorbing energy, improving the connection strength of the buckle, and further ensuring the stable cooperation of the snap-fit mounting structure 100.

[0112] In the embodiments of the present application, crushing may refer to the deformation or movement of the protrusion under pressure, resulting in a change in the contact relationship between the protrusion and the recess.

[0113] Please refer to Figure 4D , in some alternative embodiments, along the direction in which the first protrusion 311 protrudes, the angle of the apex a1 of the cross-sectional shape of the first protrusion 311 may be smaller than the angle of the apex a2 of the cross-sectional shape of the second recess 412 along the direction in which the second recess depresses.

[0114] In some examples, the difference between the angle of the apex of the cross-sectional shape of the first protrusion 311 along the direction in which the first protrusion 311 protrudes and the angle of the apex of the cross-sectional shape of the second recess 412 along the direction in which the second recess depresses does not exceed 10°.

[0115] Exemplarily, the difference between the angle of the apex a1 of the cross-sectional shape of the first protrusion 311 and the angle of the apex a2 of the cross-sectional shape of the second recess 412 may include but is not limited to 1°, 3°, 5°, 8°, 10°.

[0116] In some specific examples, the angle of the apex of the cross-sectional shape of the first protrusion 311 may be 93.4°, and the angle of the apex of the cross-sectional shape of the second recess 412 may be 90°.

[0117] In still some alternative embodiments, the angle of the apex of the cross-sectional shape of the first convex portion 311 along the protruding direction of the first convex portion 311 may be greater than the angle of the apex of the cross-sectional shape of the second concave portion 412 along the recessed direction of the second concave portion. Thus, the fitting manner of the second convex portion 411 and the first concave portion 312 may refer to Figure 4D the fitting manner of the first convex portion 311 and the second concave portion 412 in

[0118] The above embodiments can utilize the different opening angle relationships of the sawteeth in the serrated first mating surface 31 and second mating surface 41. For example, when the snap fastener is impacted, the tip of the sawtooth of the first mating surface 31 and the root of the sawtooth of the second mating surface 41 generate a mutual acting force. Subsequently, through the local crushing of the first structural member 3 or the second structural member 4 having a line-line mating relationship or a line-surface mating relationship to become a surface-surface mating relationship, thereby playing a role of engaging and energy absorption, and ensuring the stable fitting of the snap-fastening installation structure 100.

[0119] Please refer to Figure 4D , in some alternative embodiments, along the protruding direction of the first convex portion 311, the cross-sectional shape of the first convex portion 311 includes a triangle.

[0120] Through the above embodiments, by using the triangular cross-sectional shape of the first convex portion 311, the first convex portion 311 can be a triangular prism, so as to facilitate the setting of the shape of the first convex portion 311, and make the top end of the convex portion have a gap when contacting the concave portion.

[0121] Please refer to Figure 4D , in still some alternative embodiments, along the recessed direction of the second concave portion 412, the cross-sectional shape of the second concave portion 412 includes a triangle.

[0122] Through the above embodiments, by using the triangular cross-sectional shape of the second concave portion 412, the second concave portion 412 can be a triangular prism, so as to facilitate the setting of the shape of the second concave portion 412, and make the top end of the convex portion have a gap when contacting the concave portion.

[0123] Please refer to Figure 4D , in some alternative embodiments, along the protruding direction of the first convex portion 311, the cross-sectional shape of the first convex portion 311 includes a triangle. Along the recessed direction of the second concave portion 412, the cross-sectional shape of the second concave portion 412 includes a triangle. Wherein, the apex angle a1 of the cross-sectional shape of the first convex portion 311 is not equal to the apex angle a2 of the cross-sectional shape of the second concave portion 412. Thus, the apex angle of the convex portion can contact the base angle of the concave portion, so as to realize the line-line fitting between the convex portion and the concave portion, which helps to cause the contact relationship between the first mating surface and the second mating surface to be crushed when the snap-fastening installation structure is impacted, playing an effect of engaging and energy absorption, and further ensuring the stable fitting of the snap-fastening installation structure.

[0124] Figure 4E It is another front view of the snap-in mounting structure 100 provided by the embodiment of the present application in the snap-connected state.

[0125] Please refer to Figure 4E , in some other alternative embodiments, along the protruding direction of the first convex portion 311, the apex angle a1 of the cross-sectional shape of the first convex portion 311 may contact the contour side line of the cross-sectional shape of the second concave portion 412 along the recessed direction of the second concave portion 412, so that the first convex portion 311 and the second concave portion 412 form a line-plane fit, which helps to cause the contact relationship between the first mating surface and the second mating surface to be crushed when the snap-in mounting structure is impacted, achieving the effect of biting and energy absorption, and further ensuring the stable fit of the snap-in mounting structure.

[0126] In some alternative embodiments, in the state where the first structural member 3 and the second structural member 4 are snap-connected, at least one of surface-surface contact, line-plane contact, line-line contact, or point-plane contact may be formed between the first mating surface 31 and the second mating surface 41.

[0127] In the embodiment of the present application, contact is used to form a snap fit, and such contact may also be referred to as a fit. For example, line-plane contact may be referred to as line-plane fit.

[0128] In some examples, in the state where the first structural member 3 and the second structural member 4 are snap-connected, the first convex portion 311 and the second concave portion 412 are in line-line contact (for example Figure 4D ).

[0129] In some other examples, in the state where the first structural member 3 and the second structural member 4 are snap-connected, the first convex portion 311 and the second concave portion 412 are in line-plane contact (for example Figure 4E ).

[0130] Figure 4F It is another front view of the snap-in mounting structure 100 provided by the embodiment of the present application in the snap-connected state.

[0131] Please refer to Figure 4F , in some alternative embodiments, along the protruding direction of the first convex portion 311, the cross-sectional shape of the first convex portion 311 includes a trapezoid. Thus, by using the inclined surface of the trapezoid in the first convex portion 311, it helps to form a gap between the convex portion and the concave portion. For example, the cross-sectional shape of the first convex portion 311 is a rectangle.

[0132] Exemplarily, in the state where the first structural member 3 and the second structural member 4 are snap-connected, surface-surface contact may also be formed between the first convex portion 311 and the second concave portion 412. For example Figure 4FAmong them, the top end of the first convex portion 311 contacts the surface of the second concave portion 412 with its surface.

[0133] In some other alternative embodiments, along the direction in which the second concave portion 412 is recessed, the cross-sectional shape of the second concave portion 412 includes a trapezoid. A similar effect is also achieved.

[0134] In some alternative embodiments, the shapes of the first convex portion 311 and the second concave portion 412 may be different.

[0135] In some alternative embodiments, along the direction in which the first convex portion 311 protrudes, the cross-sectional shape of the first convex portion 311 includes a triangle (reference can be made to Figure 4C ), a rectangle, a trapezoid (reference can be made to Figure 4F ), or at least one of a bow shape.

[0136] Alternatively, along the direction in which the second concave portion 412 is recessed, the cross-sectional shape of the second concave portion 412 includes a triangle (reference can be made to Figure 4C ), a rectangle (reference can be made to Figure 4F ), a trapezoid, or at least one of a bow shape.

[0137] Thus, by using the different shapes of the first convex portion 311 and the second concave portion 412, it is convenient for the first mating surface and the second mating surface to contact in different forms. For example, line-line contact (reference Figure 4D ), line-surface contact (reference Figure 4E ), point-surface contact, or surface-surface contact (reference Figure 4F ) can be formed. Furthermore, by using the change in the contact type, the crushing of the mating surface is guided, playing a role in bite energy absorption, and ensuring the stable cooperation of the snap-fit mounting structure 100.

[0138] Exemplarily, as Figure 4F shown, along the first direction Y, the cross-sectional shape of the first convex portion 311 can be a trapezoid, and the cross-sectional shape of the second concave portion 412 can be a rectangle.

[0139] As Figure 4E shown, in some other alternative embodiments, the shapes of the first convex portion 311 and the second concave portion 412 can also be the same or similar. For example, along the first direction Y, the cross-sectional shapes of the first convex portion 311 and the second concave portion 412 can both be triangles.

[0140] Figure 5A Schematically shows a first mating surface 31 provided by an embodiment of the present application. Figure 5B Schematically shows a second mating surface 41 provided by an embodiment of the present application.

[0141] In some alternative embodiments, the first mating surface 31 includes a plurality of first protrusions 311. The second mating surface 41 includes a plurality of second recesses 412. Thus, by increasing the number of the protrusions and recesses, the locking between the first mating surface 31 and the second mating surface 41 can be strengthened, and the impact resistance of the snap-fit mounting structure can be improved.

[0142] Combined with the above embodiments, in some alternative embodiments, please refer to Figure 5A , the first mating surface 31 includes a plurality of first protrusions 311 arranged in an array, and the second mating surface 41 includes a plurality of second recesses 412 arranged in an array.

[0143] Please refer to Figure 5A , in some alternative embodiments, in a plane parallel to the first direction Y and the second direction Z, the cross-sectional shape of the first protrusion 311 may include, but is not limited to, any closed figure such as a circle, an ellipse, a polygon, etc.

[0144] Or, please refer to Figure 5B , in a plane parallel to the third direction U and the fourth direction V, the cross-sectional shape of the second recess 412 may include, but is not limited to, any closed figure such as a circle, an ellipse, a polygon, etc.

[0145] In some alternative embodiments, in a plane parallel to the first direction Y and the second direction Z, the cross-sectional shape of the first recess 312 may include, but is not limited to, any closed figure such as a circle, an ellipse, a polygon, etc. Or, in a plane parallel to the third direction U and the fourth direction V, the cross-sectional shape of the second protrusion 411 may include, but is not limited to, any closed figure such as a circle, an ellipse, a polygon, etc.

[0146] Figure 5A Exemplarily, it is shown that in a plane parallel to the first direction Y and the second direction Z, the cross-sectional shapes of the first protrusion 311 and the second recess 412 are circles. Figure 5B Exemplarily, it is shown that in a plane parallel to the third direction U and the fourth direction V, the shapes of the first protrusion 311 and the second recess 412 are cylinders.

[0147] In some other examples, the shapes of the first protrusion 311 and the second recess 412 may also be straight quadrangular prisms. In a plane parallel to the second direction Z and the fifth direction X, the cross-sectional shape of the first protrusion 311 may be a quadrilateral, such as a trapezoid (reference can be made to Figure 4F ).

[0148] In some alternative embodiments, the size of the first convex portion 311 may be slightly smaller than the size of the second concave portion 412. Exemplarily, when the shapes of the orthographic projections of the first convex portion 311 on the first mating surface 31 and the second concave portion 412 on the second mating surface 41 are circular, the diameter of the orthographic projection of the first convex portion 311 on the first mating surface 31 may be less than the diameter of the orthographic projection of the second concave portion 412 on the second mating surface 41 and not exceed 10%.

[0149] Through the above embodiments, by using the dimensional relationship between the first convex portion 311 and the second concave portion 412, it is helpful to achieve the concave-convex fit between the first mating surface 31 and the second mating surface 41, and further improve the connection strength of the buckle.

[0150] In some alternative embodiments, the first mating surface 31 includes a plurality of first concave portions 312 arranged in an array, and the second mating surface 41 includes a plurality of second convex portions 411 arranged in an array. Among them, the shape, dimensional relationship, contact fit relationship, etc. between the first concave portion 312 and the second convex portion 411 may refer to the first convex portion 311 and the second concave portion 412 in the above embodiments, and thus will not be elaborated here.

[0151] Figure 6 It is another structural cross-sectional view of the snap-fit mounting structure 100 in the embodiments of the present application.

[0152] In some alternative embodiments, the first convex portions 311 are arranged along the first direction Y and extend along the second direction Z, and the first direction Y intersects the second direction Z. The plurality of second concave portions 412 are arranged along the third direction U and extend along the fourth direction V, and the third direction U intersects the fourth direction V.

[0153] Alternatively, the first concave portions 312 may be arranged along the first direction Y and extend along the second direction Z, and the second convex portions 411 may be arranged along the third direction U and extend along the fourth direction V. The contact between the first concave portions 312 and the second convex portions 411 may refer to the contact between the first convex portions 311 and the second concave portions 412.

[0154] Exemplarily, the first direction Y and the second direction Z may be perpendicular to each other, and the third direction U and the fourth direction V may be perpendicular to each other.

[0155] The first convex portions 311 and the first concave portions 312 may be alternately arranged, and the second concave portions 412 and the second convex portions 411 may be alternately arranged.

[0156] Through the above embodiments, the first convex portions 311 of the first mating surface 31 are arranged in a strip shape, and the second concave portions 412 of the second mating surface 41 are arranged in a strip shape. Through the arrangement and fit of the concave or convex portions, the concave-convex fit between the first mating surface and the second mating surface can also be achieved, and the connection strength of the buckle can be improved.

[0157] ForFigure 6 For example, a part of the drawings in the embodiments of the present application shows the morphology of the snap - type mounting structure 100 in the snap - connected state. While maintaining the relative positional relationship between the first mating surface 31 and the second mating surface 41, the first structural member 3 and the second structural member 4 are separated to illustrate the structural details of the snap - type mounting structure 100. It can be understood that in actual situations, when the snap - type mounting structure 100 is in the snap - connected state, the first structural member 3 and the second structural member 4 may be in contact with each other.

[0158] The embodiments of the present application also provide some alternative embodiments of the snap - type mounting structure 100 below.

[0159] Please refer to Figure 6 , in the first alternative embodiment, when the first structural member 3 and the second structural member 4 are in the snap - connected state, the first mating surface 31 is parallel to the second mating surface 41.

[0160] In this embodiment, the first direction Y is parallel to the third direction U, and the second direction Z is parallel to the fourth direction V.

[0161] In this embodiment, during the process of the first structural member 3 and the second structural member 4 being snap - connected or decoupled, the first mating surface 31 moves in a direction parallel to the second direction Z, or the second mating surface 31 moves in a direction parallel to the fourth direction V, so that the first mating surface 31 and the second mating surface 41 form a concave - convex fit, and then the first structural member 3 and the second structural member 4 are snap - connected.

[0162] Among them, during the process of the first structural member 3 and the second structural member 4 being snap - connected, the first structural member 3 and the second structural member 4 can also move in the fifth direction X to achieve decoupling.

[0163] Through the above - mentioned embodiments, the extending direction of the concave part or the convex part can be parallel to the moving direction of the first mating surface 31 and the second mating surface 41 when the snap is snap - connected or decoupled, so that the snap can be snap - connected or decoupled along the extending direction of the concave part or the convex part, enhancing the easy - assembly property and detachable property of the snap - type mounting structure 100.

[0164] Figure 7A is another structural schematic diagram of the snap - type mounting structure 100 in the embodiments of the present application. Figure 7B is Figure 7A a structural cross - section view of the snap - type mounting structure 100 shown.

[0165] Please refer to Figure 7A and Figure 7B, in the second alternative embodiment, when the first structural member 3 is engaged with the second structural member 4, the first mating surface 31 is parallel to the second mating surface 41, the first direction Y is parallel to the third direction U, and the second direction Z is parallel to the fourth direction V.

[0166] In this embodiment, during the process of the first structural member 3 being engaged with the second structural member 4, the first structural member 3 and the second structural member 4 move along the fifth direction X, and moreover, the first mating surface 31 or the second mating surface 41 moves in a direction parallel to the first direction Y.

[0167] Through the above embodiments, the buckle can be disengaged along the arrangement direction of the concave portion or the convex portion, and the mutual acting force between the concave portion and the convex portion is also parallel to the disengagement direction of the buckle, thereby further hindering the disengagement of the buckle, and thus improving the impact resistance of the snap-fit mounting structure 100 and further enhancing the reliability of the snap-fit mounting structure 100.

[0168] Figure 8 It is another schematic structural diagram of the snap-fit mounting structure 100 in the embodiments of the present application.

[0169] Please refer to Figure 8 , in the third alternative embodiment, when the first structural member 3 is engaged with the second structural member 4, the first mating surface 31 is parallel to the second mating surface 41, the first direction Y is parallel to the third direction U, and the second direction Z is parallel to the fourth direction V.

[0170] In this embodiment, during the process of the first structural member 3 being engaged with the second structural member 4, the first structural member 3 or the second structural member 4 moves along the fifth direction X, and moreover, the first mating surface 31 or the second mating surface 41 moves in a direction perpendicular to the fifth direction X. The moving direction of the first mating surface 31 or the second mating surface 41 intersects with the first direction Y and the second direction Z, and moreover, the angle between the moving direction of the first mating surface 31 or the second mating surface 41 and the first direction Y is greater than 0° and less than 90°, and the angle between the moving direction of the first mating surface 31 or the second mating surface 41 and the second direction Z is greater than 0° and less than 90°.

[0171] In the above first to third embodiments, the first mating surface 31 and the second mating surface 41 are parallel and opposite to each other, which helps the first convex portion 311 to be embedded into the second concave portion 412 and the second convex portion 411 to be embedded into the first concave portion 312, and can help to improve the easy assembly and disassembly of the snap-fit mounting structure.

[0172] Figures 9A - 9C It is another schematic structural diagram of the snap-fit mounting structure 100 in the embodiments of the present application.

[0173] Please refer to Figure 9A, in the fourth alternative embodiment, when the first structural member 3 and the second structural member 4 are engaged and connected, the first mating surface 31 and the second mating surface 41 are not parallel, and the first direction Y is parallel to the third direction U, and the second direction Z is not parallel to the fourth direction V.

[0174] In this embodiment, the first direction Y and the third direction U may be parallel to the extending direction of the intersection line of the first mating surface 31 and the second mating surface 41.

[0175] Among them, the intersection line of the first mating surface 31 and the second mating surface 41 refers to the line segment where the first mating surface 31 and the second mating surface 41 intersect as a whole.

[0176] In this embodiment, during the process of engaging and connecting the first structural member 3 and the second structural member 4, the first structural member 3 or the second structural member 4 moves along the fifth direction X, and moreover, the first mating surface 31 or the second mating surface 41 moves in a direction perpendicular to the fifth direction X. Exemplarily, the moving direction of the first mating surface 31 is parallel to the second direction Z, and the moving direction of the second mating surface 41 is parallel to the fourth direction Z.

[0177] Through the above embodiments, the first mating surface 31 as a whole and the second mating surface 41 as a whole are not parallel, reducing the contact area between the first mating surface as a whole and the first mating surface as a whole, which helps to cause the contact relationship between the first mating surface 31 and the second mating surface 41 to be crushed when the snap-fit mounting structure is impacted, playing a role in energy absorption and further improving the impact resistance of the snap-fit mounting structure.

[0178] Please refer to Figure 9B , in the fifth alternative embodiment, when the first structural member 3 and the second structural member 4 are engaged and connected, the first mating surface 31 and the second mating surface 41 are not parallel, and the first direction Y is not parallel to the third direction U, and the second direction Z is parallel to the fourth direction V.

[0179] In this embodiment, the second direction Z and the fourth direction V are parallel to the extending direction of the intersection line of the first mating surface 31 and the second mating surface 41.

[0180] In this embodiment, during the process of engaging and connecting the first structural member 3 and the second structural member 4, the first structural member 3 and the second structural member 4 move relative to each other, and moreover, the first structural member 3 or the second structural member 4 moves along the fifth direction X, and moreover, the first mating surface 31 or the second mating surface 41 moves in a direction perpendicular to the fifth direction X. Among them, the moving direction of the first mating surface 31 is parallel to the first direction Y, and the moving direction of the second mating surface 41 is parallel to the third direction U.

[0181] In the fourth to fifth embodiments described above, the first mating surface 31 and the second mating surface 41 can achieve an overall line-surface fit, so that when the snap-on installation structure 100 is impacted, it can be transformed into a surface-surface fit by causing local crushing at the line-surface fit between the first structural member 3 and the second structural member 4. This process can play a role in biting and absorbing energy, reduce the impact of the impact force on the buckle, reduce the possibility of the buckle being disengaged, and further ensure the stable fit of the snap-on installation structure 100.

[0182] In the fourth to fifth embodiments described above, the following examples are also included:

[0183] Example 1: Please refer to Figure 9A , an end of the first mating surface 31 away from the elastic portion 12 makes line-surface contact with the second mating surface 41 .

[0184] Example 2: Please refer to Figure 9C , one end of the second mating surface 41 close to the elastic portion 12 is in line-surface contact with the first mating surface 31 .

[0185] For example 2, please refer to Figure 9C The edge angle of one end of the second mating surface 41 that contacts the first mating surface 31 may be an acute angle. This allows the second mating surface 41 as a whole to be partially crushed when subjected to force, and the first mating surface 31 and the second mating surface 41 can change from line-surface contact to surface-surface contact. In this process, the energy absorption of deformation is used to further improve the reliability of the snap-on installation structure 100.

[0186] In some optional embodiments, such as Figure 7B As shown, the height H1 of the first convex portions 311 is the same, and the depth D2 of the second concave portions 412 is the same. Alternatively, the height H2 of the second convex portions 411 is the same, and the depth D1 of the first concave portions 312 is the same.

[0187] Figures 10A - 10B are some structural cross-sectional views of the snap-on installation structure provided in the embodiments of the present application. Figures 10C - 10D These are some further structural schematic diagrams of the snap-on installation structure provided in the embodiments of the present application.

[0188] In some optional implementations, the first structural member 3 or the second structural member 4 may be obtained by die-casting.

[0189] In some examples, when the second structural member 4 is in sheet form and thin enough, the shape of the second protrusion 411 or the second recess 412 can be presented on another surface of the second structural member 4 (for example, Figure 10A ).

[0190] In still other examples, when the second structural member 4 is not sheet-shaped or is a sheet-shaped member with sufficient thickness, the shape of the second convex portion 411 or the second concave portion 412 may not be presented on the other surface of the second structural member 4 relative to the second mating surface 41 (e.g., Figure 9B ).

[0191] As Figure 10A shown, in some alternative embodiments, along the direction in which the first convex portion 311 protrudes, the sizes of the plurality of first convex portions 311 are not completely the same.

[0192] In some alternative embodiments, along the direction in which the second concave portion 412 depresses, the sizes of the plurality of second concave portions 412 are not completely the same.

[0193] In some alternative embodiments, along the direction in which the second convex portion 411 protrudes, the sizes of the second convex portions 411 are not completely the same. Along the direction in which the first concave portion 312 depresses, the sizes of the plurality of first concave portions 312 are not completely the same.

[0194] Thus, by reducing the need for dimensional standardization, the first mating surface 31 and the second mating surface 41 are more easily fabricated.

[0195] Furthermore, in combination with the above embodiments, the dimensional differential design of the convex or concave portions can also be utilized to enhance the ease of assembly or the impact resistance of the snap-fit mounting structure.

[0196] Please refer to Figure 10A , in some alternative embodiments, along the first direction Y, or the direction parallel to the arrangement of the first convex portions 311, as the distance from the elastic portion 12 increases, the protruding height H1 of the first convex portions 311 gradually decreases. Along the third direction U, or the direction parallel to the arrangement of the second concave portions 412, as the distance from the elastic portion 12 increases, the depression depth D2 of the second concave portions 412 gradually decreases.

[0197] Please refer to Figure 10B , in still other alternative embodiments, parallel to the first direction Y, or the direction parallel to the arrangement of the first convex portions 311, as the distance from the elastic portion 12 increases, the protruding height H1 of the first convex portions 311 gradually decreases. Parallel to the third direction U, or the direction parallel to the arrangement of the second concave portions 412, as the distance from the elastic portion 12 decreases, the depression depth D2 of the second concave portions 412 gradually decreases.

[0198] Please refer to Figure 10C , in still other alternative embodiments, along the second direction Z, or the direction along which the first convex portions 311 extend, as the distance from the elastic portion 12 increases, the protruding height of the first convex portions 311 gradually decreases. Along the fourth direction V, or the direction along which the second concave portions 412 extend, as the distance from the elastic portion 12 increases, the depression depth of the second concave portions 412 gradually decreases.

[0199] Please refer to Figure 10D In some alternative embodiments, parallel to the second direction Z, or along the direction in which the first convex portion 311 extends, as approaching the elastic portion 12, the protruding height of the first convex portion 311 gradually decreases. Parallel to the fourth direction V, or along the direction in which the second concave portion 412 extends, as approaching the elastic portion 12, the recessed depth of the second concave portion 412 gradually decreases.

[0200] Through the above embodiments, by using the decreasing protruding height of the convex portion or the recessed depth of the concave portion, it is possible to make the assembly or disengagement of the first structural member 3 and the second structural member 4 easier, and also to make the deformation amount of the first structural member 3 or the second structural member 4 less during the process of snap connection or disengagement, thereby increasing the fatigue life of the snap-fit mounting structure. Moreover, the dimensional change of the convex portion or the concave portion also helps to further achieve different mating relationships such as point-line mating, point-surface mating, line-surface mating or line-line mating between the first mating surface 31 and the second mating surface 41, further improving the reliability of the snap-fit mounting structure.

[0201] In the embodiments of the present application, the first structural member 3 and the second structural member 4 may specifically be structural members in an electronic device or other products. For example, it can be applied to the snap connection between an antenna and a host in a router, a set-top box, etc.

[0202] Figure 11 It is another structural cross-sectional view of the snap-fit mounting structure provided by the embodiments of the present application.

[0203] Please refer to Figure 11 In some alternative embodiments, the first structural member 3 is connected to the antenna structural member 101, and the second structural member 4 is connected to the host structural member 201. In the state where the first structural member 3 and the second structural member 4 are snap-connected, the antenna structural member 101 is connected to the host structural member 201.

[0204] Through the above embodiments, the snap-fit mounting structure 100 can be applied to an electronic device having a connection requirement between an antenna and a host to realize the connection between the antenna structural member 101 and the host structural member 201.

[0205] Please refer to Figure 11 In some alternative embodiments, the antenna structural member 101 and the host structural member 201 may be in contact, and under the condition of being externally impacted, they produce a mutual limiting effect. Thus, together with the mating relationship between the first mating surface 31 and the second mating surface 41, a snap connection lock is formed to realize the connection between the antenna structural member 101 and the host structural member 201.

[0206] In some examples, the first structural member 3 further includes an elastic portion 12 and a first engaging portion 10. The antenna structural member 101 is connected to one end of the elastic portion 12 relative to the first engaging portion 10, and the first mating surface 31 is located on the first engaging portion 10. The second structural member 4 further includes a second fixing portion 42, the second fixing portion 42 is connected to the host structural member 201, and the second mating surface 41 is located on the second engaging portion 20. Through the snap connection between the first structural member 3 and the second structural member 4, the antenna structural member 101 contacts the host structural member 201.

[0207] Wherein, the first engaging portion 10 and the second engaging portion 20 can be structures directly used to form the snap mating surface.

[0208] Through the above embodiments, the first fixing portion 32 and the second fixing portion 42 can be used to contact and cooperate with each other for limiting, and combined with the cooperation between the first mating surface 31 and the second mating surface 41, the first structural member 3 and the second structural member 4 can be integrally locked, realizing the function of the snap.

[0209] Through the above embodiments, by the combined action of the cooperation between the first structural member 3 and the second structural member 4 and the cooperation between the antenna structural member 101 and the host structural member 201, a snap locking relationship is formed, thereby completing the connection between the antenna structural member 101 and the host structural member 201.

[0210] In some alternative embodiments, when the antenna structural member 101 is subjected to a force along the fifth direction X, the top end of the first convex portion 311 deforms or moves within the second concave portion 412.

[0211] In still some other alternative embodiments, when the antenna structural member 101 is subjected to a force along the fifth direction X, the top end of the second convex portion 411 deforms or moves within the first concave portion 312.

[0212] Wherein, the fifth direction X can be parallel to the direction in which the first mating surface 31 faces the second mating surface 41. Thus, by the mutual limiting effect between the convex portion and the concave portion, the first mating surface 31 and the second mating surface 41 are locked. Moreover, the deformation of the first convex portion 311 or the second convex portion 411 can also play a role in biting and energy absorption, improving the impact resistance of the snap, so as to be able to contain the tendency of the antenna structural member to separate from the host structural member from multiple directions and improve the connection performance between the antenna structural member and the host structural member.

[0213] The embodiment of the present application also provides a non-electronic device, which includes the snap-in mounting structure 100 in the above embodiments.

[0214] An embodiment of the present application further provides an electronic device, which includes a first component, a second component, and the snap-fit mounting structure 100 in any of the above embodiments. The first component is connected to the first structural member 3, and the second component is connected to the second structural member 4.

[0215] In some alternative embodiments, the electronic device includes a router or a set-top box. The first component may include the antenna structural member 101 in the above embodiment, and the second component may include the host structural member 201 in the above embodiment.

[0216] In some examples, the router may include a Fiber to the Room (FTTR) router, a Customer Premise Equipment router. For example, a 5th Generation Mobile Communication Technology (5G) router, etc.
