DETAIL DESCRIPTION OF EMBODIMENTS

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions according to the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. Apparently, the described embodiments are merely some, but not all, of the embodiments of the present disclosure. The components of the embodiments of the present disclosure, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Therefore, the following detailed description of the embodiments of the present disclosure, provided in the accompanying drawings, is not intended to limit the scope of the present disclosure as claimed, but is merely representative of selected embodiments of the present disclosure. All other embodiments, which can be derived by those skilled in the art from the embodiments of the present disclosure without making any creative effort, shall fall within the protection scope of the present disclosure.


Unless otherwise defined, technical or scientific terms used in the present disclosure are intended to have general meanings as understood by those of ordinary skill in the art to which the present disclosure belongs. The words “first”, “second” and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used merely for distinguishing different components from each other. The word “comprise” or “include” or the like means that the element or item preceding the word contains elements or items that appear after the word or equivalents thereof, but does not exclude other elements or items. The words “upper”, “lower”, “left”, “right”, or the like are merely used to indicate a relative positional relationship, and when an absolute position of the described object is changed, the relative positional relationship may be changed accordingly.


Reference to “a plurality of or several” in the present disclosure means two or more. The term “and/or” describes an association relationship of associated objects, which may include three relationships; for example, A and/or B may refer to: A alone, A and B, or B alone. The character “/” generally indicates that the former and latter associated objects are in an “or” relationship.


It should be noted that the glass or ceramic rear cover can reflect light, giving people a transparent aesthetic feeling, which is not possessed by metal or plastic materials. In addition, the glass or ceramic rear cover is not likely to block electric waves, and thus is more suitable for near field communication (NFC) and wireless charging. For example, since the glass or ceramic is not likely to block electric waves, when an NFC function, for example, swiping a traffic card, swiping a door guard, payment, data transmission or the like, is used, the response can be more sensitive, thereby improving the user experience. For another example, since the glass or ceramic has little resistance to the received electric waves, an electronic product using a glass or ceramic rear cover is more suitable for wireless charging.


In the existing art, most glass or ceramic rear covers of the current electronic products on the market are manufactured by a bonding process, where the battery cannot be removed, which has the advantages of compact and thin machine body, and good waterproof performance. However, the disadvantages are also obvious. For example, since the battery is not removable, the electronic product has to be replaced by a new one when the lifetime of the battery carried therein expires, thereby shortening the product replacement period. In addition, once the electronic product with the non-detachable rear cover has problems, the user has to seek help from a professional person, and cannot disassemble the electronic product by himself/herself.


A main composition of glass or ceramic is silicon dioxide, which is an amorphous material having a molecular structure typically lacking stability. In simple terms, the silicon dioxide material is fragile. While the glass or ceramic rear cover is manufactured by a bonding process, bonding is relatively difficult limited by the fragility of the material. FIG. 1a is a schematic diagram of bonding a glass sheet individually in the existing art. As shown in FIG. 1a, a plurality of individual buckles 001 are prepared, and then each buckle 001 is separately bonded to a glass sheet 200. FIG. 1b is a schematic diagram of possible deviation directions of a bonded glass sheet in the existing art. As shown in FIG. 1b, buckles 001 with serial number 01 to 10 are bonded to a glass rear cover in total. Since the buckles 001 are individually installed, it is hard to guarantee relatively accurate positions of the buckles 001, resulting in deviations of the buckles 001 in various directions as shown in FIG. 1b. Any skew or misplaced buckle 001 will make the glass rear cover unable to be installed. Even a slight deviation in the position of a buckle 001 will cause skew and non-uniform stress after installation, causing falling of the buckle 001 and even breakage of the glass sheet 200, and thus seriously influencing the product yield. Even if the installed product is in good condition, the product yield will be seriously influenced, leaving hidden dangers in use for subsequent users and bringing continuous after-sale repairs.


In view of this, an embodiment of the present disclosure provides a buckle assembly configured to manufacture a package structure of an electronic product, so that the package structure has buckle structures in the buckle assembly, and the package structure of the electronic product is detachable.


The following provides a detailed description of a specific structure of a buckle assembly according to an embodiment of the present disclosure. FIG. 2 is a schematic structural diagram of a buckle assembly according to an embodiment of the present disclosure. As shown in FIG. 2, a buckle assembly 100 includes a plurality of buckle structures 101 and a plastic frame structure 102. An outer contour of the plastic frame structure 102 is matched with an outer contour of a housing 200 of an electronic product. The plastic frame structure 102 is provided with a plurality of openings, and each buckle structure 101 is embedded into one of the openings. The plurality of buckle structures 101 and the plastic frame structure 102 form an integral structure by injection molding.


The outer contour of the housing 200 is matched with the outer contour of the plastic frame structure 102, so that the buckle structures 101 embedded into the plastic frame structure 102 are also matched with the outer contour of the housing 200. Meanwhile, the plurality of buckle structures 101 and the plastic frame structure 102 form an integral structure by injection molding, so that relative positions of the buckle structures 101 are relatively accurate, and position deviation of the buckle structures 101 when aligned with the housing 200 is avoided. In addition, the plurality of buckle structures 101 and the plastic frame structure 102 form an integral structure by injection molding, so that in the manufacturing process, this integral structure is connected to the housing 200 to prevent a concentrated stress on the housing 200 when the buckle structures 101 are installed individually. In other words, the buckle assembly 101 in the embodiment of the present disclosure is formed as an integral structure by injection molding, and the plurality of buckle structures 101 are installed with the housing 200 at the same time to disperse a stress on the housing 200, so that the risk of breakage of a local portion of the housing 200 due to pressure during the dwell process is reduced, the quality of the package structure 000 is guaranteed, and the yield of the electronic product is improved.


The buckle structure 101 in the embodiment of the present disclosure is a structure capable of cooperating with another part to implement integral locking, and the buckle structure 101 is typically made of a plastic material with certain flexibility. Apparently, the material of the buckle structure 101 in the embodiment of the present disclosure is not limited to plastic, and may be any other material with certain flexibility. The buckle structure 101 may be cooperated with a body of the electronic product to implement locking.


The number of buckle structures 101 is the same as the number of openings in the plastic frame structure 102. The plurality of buckle structures 101 and the plastic frame structure 102 form an integral structure by injection molding, where the integral structure formed by injection molding is a closed frame structure, wherein the frame structure is relatively stable, and the buckle assembly 100 has an accurate relative position on the frame structure, so as to facilitate subsequent assembling with the glass sheet 200 (or ceramic sheet 200) and implement accurate alignment.


Here, the housing of the electronic product may be understood as a housing of a package structure of the electronic product. The housing may be made of a material including, but not limited to, a relatively thin and fragile material such as glass, ceramic, or the like. Exemplarily, the housing 200 of the electronic product may be selected as a glass sheet or ceramic sheet that is aesthetically pleasing and not likely to block electric waves, which may be specifically a glass sheet or a ceramic sheet on a rear cover of a mobile phone.


The present disclosure will be described by taking the housing 200 being a glass sheet as an example. Bonding is relatively difficult limited by the fragility of the glass. In view of this, the present disclosure provides a buckle assembly 100, which includes a combination of any one or more of the following embodiments with the buckle assembly 100 described above, so as to assist the assembly between the buckle structures 101 and the glass sheet 200, and implement accurate positioning, while reducing the risk of breakage of a local portion of the glass sheet 200 due to pressure during the dwell process, ensuring the quality of the resulting package structure 000, and improving the yield of the electronic product.


In some embodiments, FIG. 3 is a schematic structural diagram of another buckle assembly according to an embodiment of the present disclosure. As shown in FIG. 3, a buckle assembly 100 includes a plurality of buckle structures 101, one plastic frame structure 102, and one support 103. An outer contour of the plastic frame structure 102 is matched with an outer contour of a housing 200 of an electronic product. The plastic frame structure 102 is provided with a plurality of openings, and each buckle structure 101 is embedded into one of the openings. The support 103 is disposed in an annular area defined by the plastic frame structure 102. The buckle assembly 100 further includes the support 103 in an annular region enclosed by the plastic frame structure 102. The support 103 is divided into a plurality of branches each having a first end and a second end. First ends O of different branches are connected, while the second end of each branch is connected to one of the buckle structures 101. The plurality of buckle structures 101, the one plastic frame structure 102, and the one support 103 form an integral structure by injection molding. Therefore, while relative positions of the buckle structures 101 are relatively accurate, and position deviation of the buckle structures 101 when aligned with the housing 200 is avoided, the overall strength of the buckle assembly 100 can be increased, deformation of the buckle structures 101 can be effectively alleviated, the risk of breakage of a local portion of the housing 200 due to pressure during the dwell process is reduced, and thus the yield of the buckle structures 101 assembled with the glass sheet 200 is increased.


The support 103 is a molded structure of an injection molding raw material in branch channels of the mold during the injection molding process of the buckle structures 101. As shown in FIG. 3, reference 30 indicates a molded structure of an injection molding raw material in a main channel of the mold during the injection molding process of the buckle structures 101. The injection molding raw material flows into the branch channels from the main channel and then into a gate, to form an integral structure of the plurality of buckle structures 101, the plastic frame structure 102 and the support 103, i.e., the buckle assembly 100, by injection molding.


Exemplarily, at least some of the plurality of branches share at least some structures. As shown in FIG. 3, the support 103 includes a structure A, a structure A1, a structure A2, a structure A11, a structure A12, a structure A21, a structure A22, a structure B, a structure B1, a structure B2, a structure B11, a structure B12, a structure B21, a structure B22, a structure C, and a structure D. The structure A, the structure B, the structure C and the structure D are connected at one end (i.e., point O). The other end of the structure A connects the structure A1 and the structure A2, the structure A1 connects the structure A11 and the structure A12, and the structure A2 connects the structure A21 and the structure A22. The other end of the structure B connects the structure B1 and the structure B2, the structure B1 connects the structure B11 and the structure B12, and the structure B2 connects the structure B21 and the structure B22. A branch of the support 103 connecting the buckle structures 101 (A′11) includes the structure A, the structure A1, and the structure A11, and a branch connecting the buckle structures 101 (A′12) includes the structure A, the structure A1, and the structure A12, where the two branches share the structure A and the structure A1. A branch of the support 103 connecting the buckle structures 101 (A′21) includes the structure A, the structure A2, and the structure A21, and a branch connecting the buckle structures 101 (A′22) includes the structure A, the structure A2, and the structure A22, where the two branches share the structure A and the structure A2. The branch of the support 103 connecting the buckle structures 101 (A′11) and the branch connecting the buckle structures 101 (A′12) share the structure A with the branch of the support 103 connecting the buckle structures 101 (A′21) and the branch connecting the buckle structures 101 (A′22). A branch of the support 103 connecting the buckle structures 101 (B′11) includes the structure B, the structure B1, and the structure B11, and a branch connecting the buckle structures 101 (B′12) includes the structure B, the structure B1, and the structure B12, where the two branches share the structure B and the structure B1. A branch of the support 103 connecting the buckle structures 101 (B′21) includes the structure B, the structure B2, and the structure B21, and a branch connecting the buckle structures 101 (B′22) includes the structure B, the structure B2, and the structure B22, where the two branches share the structure B and the structure B2. The branch of the support 103 connecting the buckle structures 101 (B′11) and the branch connecting the buckle structures 101 (B′12) share the structure B with the branch of the support 103 connecting the buckle structures 101 (B′21) and the branch connecting the buckle structures 101 (B′22). Compared with independent branches connecting the buckle structures 101, the above structural design of the support 103 can reduce the material consumption and save the cost, while reducing the injection molding time of the buckle assembly 100 and improving the efficiency of the injection molding.



FIG. 4 is a schematic diagram of an exemplary buckle assembly according to an embodiment of the present disclosure, FIG. 5 is a partial enlarged view of at position M of FIG. 4, and FIG. 6 is a sectional view taken along line B-B of FIG. 4.


In some embodiments, as shown in FIGS. 4, 5 and 6, each branch includes a branch end part 31 at the second end, and a branch body part 32 integrally formed with the branch end part 31. The branch end part 31 has a first surface connected to one of the buckle structures 101, and a second surface and a third surface 03 which are connected to the first surface. A connection position between the first surface and the second surface is opposite to a connection position between the first surface and the third surface 03 in a first direction Y. Here, the first direction Y may be understood as a thickness direction of the buckle assembly 100. Each of the buckle structures 101 includes a buckle body part 11 and a buckle connection part 12 integrally formed with the buckle body part. The second end of the branch is connected to the buckle body part 11. The second surface is farther away from the buckle connection part 12 than the third surface 03. A connection surface between the buckle body part 11 and the branch forms a first dihedral angle α with the second surface, where the first dihedral angle α is smaller than 90°.


It should be noted that for the process of assembling the buckle assembly 100 with the glass sheet 200 to form the package structure 000, the support 103 and the plastic frame structure 102 are cut out from the buckle assembly 100, while only the buckle structures 101 are reserved and connected to the glass sheet 200. In this embodiment, however, by forming the first dihedral angle α, so that a certain gap is formed between the connection position between the branch end part 31 and the buckle body part 11 and the sixth surface of the buckle body part 11. The sixth surface is a surface to be connected to the glass sheet 200. As a result, by providing the gap, the influence of cutting needles 43 on the glass sheet 200 in the subsequent cutting process can be avoided, and the risk of damaging the glass sheet 200 by the cutting needles 43 is reduced.


Further, in combination with the above embodiments, as shown in FIG. 6, the connection surface between the buckle body part 11 and the branch forms a second dihedral angle β with the third surface 03, where the second dihedral angle β is smaller than 90°.


Here, by forming the second dihedral angle β, the branch end part 31 is substantially thinned, especially that a thickness at the second end of the branch is substantially reduced compared with a thickness of the branch body part 32, so that the connection position between the branch end part 31 and the buckle body part 11 is at a weak point N1, which facilitates the subsequent cutting. In addition, the branch end part 31 in this embodiment has a wedge-shaped structure. A thickness of the branch end part 31 gradually decreases in a direction approaching the buckle body part 11 connected to the branch end part 31, which ensures the strength at the connection position between the branch end part 31 and the branch body part 32, while satisfying the requirement of easy breaking of the connection position between the branch end part 31 and the buckle body part 11.


In some embodiments, as shown in FIG. 6, the buckle body part 11 has a first thickness H1 in a direction X toward the branch end part 31 connected to the buckle body part 11. A connection position between the branch end part 31 and the buckle body part 11 has a second thickness H2 in the first direction Y. The second thickness H2 is less than or equal to half of the first thickness H1. Such a structure satisfies the condition of easy breaking at the weak point N1.


In some embodiments, as shown in FIGS. 5 and 6, each branch includes a branch end part 31 at the second end, and a branch body part 32 integrally formed with the branch end part 31. The branch body part 32 includes a fourth surface connected to the second surface. Each of the buckle structures 101 has a fifth surface 05 connected to the branch end part 31, and a sixth surface and a seventh surface 07 which are connected to the fifth surface 05. A connection position between the fifth surface 05 and the sixth surface is opposite to a connection position between the fifth surface 05 and the seventh surface 07 in the first direction Y. An extension plane of the fourth surface is flush with an extension plane of the sixth surface.


This embodiment is combined with any one or more of the above embodiments, and the extension plane of the fourth surface is flush with the extension plane of the sixth surface, so that the overall strength of the buckle assembly 100 can be increased, and in the following press-fit process, an overall supporting effect of the glass sheet 200 by the buckle assembly 100 is improved, and the stress on the glass sheet 200 is further dispersed. Therefore, the risk of breakage of a local portion of the glass sheet 200 due to pressure during the dwell process is reduced, the quality of the package structure 000 is guaranteed, and the yield of the electronic product is improved.


In some embodiments, each branch is in a special-shaped structure, and has the same path length from the first end O to the second end. As shown in FIG. 3, a sum of path lengths of the structure A, the structure A1 and the structure A11, a sum of path lengths of the structure A, the structure A1 and the structure A12, a sum of path lengths of the structure B, the structure B1 and the structure B11, a sum of path lengths of the structure B, the structure B1 and the structure B12, a path length of the structure C, and a path length of the structure D, are the same. In other words, each branch channel has the same path length in the injection molding process, so that a flow rate of the injection molding raw material can be controlled to make sure that various gates are fed and fully filled at the same time, and simultaneously cooled and molded, thereby ensuring the consistency of the buckle structures 101, and increasing the efficiency of injection molding.


In addition, in combination with the above embodiments, in the support 103, the design of at least some of the plurality of branches sharing at least some structures can facilitate the arrangement of branches with the same path length. Meanwhile, the material consumption is reduced, the cost is saved, and the efficiency of the injection molding is improved.


In some embodiments, FIG. 7 is a sectional view taken along line C-C of FIG. 4. As shown in FIGS. 4, 5 and 7, the plastic frame structure 102 includes a multi-segment bridge structure 2. The bridge structure 2 includes two bridge end parts 21 and a bridge body part 22 sandwiched between the two bridge end parts 21. Each bridge end part 21 has an eighth surface connected to one of the buckle structures 101, and a ninth surface and a tenth surface 010 which are connected to the eighth surface. A connection position between the eighth surface and the ninth surface is opposite to a connection position between the eighth surface and the tenth surface 010 in a first direction Y. Each of the buckle structures 101 includes a buckle body part 11 and a buckle connection part 12 integrally formed with the buckle body part. The bridge end part 21 is connected to the buckle body part 11. The ninth surface is farther away from the buckle connection part 12 than the tenth surface 010. A connection surface between the buckle body part 11 and the bridge end part 21 forms a third dihedral angle γ with the ninth surface, where the third dihedral angle γ is smaller than 90°.


It should be noted that for the process of assembling the buckle assembly 100 with the glass sheet 200 to form the package structure 000, the support 103 and the plastic frame structure 102 are cut out from the buckle assembly 100, while only the buckle structures 101 are reserved and connected to the glass sheet 200. In this embodiment, however, by forming the third dihedral angle γ, a certain gap is formed between the connection position between the bridge end part 21 and the buckle body part 11 and the sixth surface of the buckle body part 11. The sixth surface is a surface to be connected to the glass sheet 200. As a result, by providing the gap, the influence of cutting needles 43 on the glass sheet 200 in the subsequent cutting process can be avoided, and the risk of damaging the glass sheet 200 by the cutting needles 43 is reduced.


Further, the bridge body part 22 has a thickness smaller than the buckle body part 11, and the connection position between the bridge end part 21 and the buckle body part 11 has a thickness smaller than the bridge body part 22, so that the connection position between the bridge end part 21 and the buckle body part 11 is at a weak point N2, which facilitates the subsequent cutting.


In addition, in this embodiment, the plastic frame structure 102 includes a multi-segment bridge structure 2. The multi-segment bridge structure 2 connects all the buckle structures 101 into a whole, so that the relative positions of all buckle structures 101 are ensured to be unchanged. Meanwhile, the bridge structure 2 can also effectively prevent deformation or displacement of the buckle structures 101 during injection molding due to an excessive pressure of the injection machine for jetting the injection molding raw material.


In some embodiments, as shown in FIG. 5, the bridge body part 22 includes an eleventh surface and a twelfth surface 012 disposed opposite to each other in the first direction Y. The twelfth surface 012 of the bridge body part 22 is flush with the tenth surface 010 of the bridge end part 21, to ensure the connection strength between the bridge structure 2 and the buckle structures 101.


Further, as shown in FIG. 7, the bridge body part 22 has a third thickness H3 in the first direction Y. A connection position between the bridge end part 21 and the buckle body part 11 has a fourth thickness H4 in the first direction Y. The fourth thickness H4 is less than or equal to half of the third thickness H3. Such a structure satisfies the condition of easy breaking at the weak point N2.


In combination with the above embodiments, the provision of the bridge structure 2 ensures the connection strength with the buckle structures 101, and facilitates subsequent cutting of the bridge structure 2.


In some embodiments, as shown in FIGS. 5 and 7, the bridge body part 22 includes an eleventh surface and a twelfth surface 012 disposed opposite to each other in the first direction Y. Each of the buckle structures 101 has a fifth surface 05 connected to the plastic frame structure 102, and a sixth surface and a seventh surface 07 which are connected to the fifth surface 05. A connection position between the fifth surface 05 and the sixth surface is opposite to a connection position between the fifth surface 05 and the seventh surface 07 in the first direction Y. An extension plane of the eleventh surface is flush with an extension plane of the sixth surface.


This embodiment is combined with any one or more of the above embodiments, and the extension plane of the eleventh surface is flush with the extension plane of the sixth surface, so that the overall strength of the buckle assembly 100 can be increased, and in the following press-fit process, an overall supporting effect of the glass sheet 200 by the buckle assembly 100 is improved, and the stress on the glass sheet 200 is further dispersed. Therefore, the risk of breakage of a local portion of the glass sheet 200 due to pressure during the dwell process is reduced, the quality of the package structure 000 is guaranteed, and the yield of the electronic product is improved.


In some embodiments, as shown in FIG. 2, the plurality of buckle structures 101 are centrosymmetric about a center of the plastic frame structure 102, which ensures uniform distribution of the resulting buckle structures 101 over the package structure 000, and ensures the sealing performance of the package. Meanwhile, the plurality of buckle structures 101 centrosymmetric about a center of the plastic frame structure 102 also ensure the overall strength of the buckle assembly 100.


In some embodiments, as shown in FIG. 2, the buckle assembly 100 further includes a support 103. The support 103 is centrosymmetric about a center of the plastic frame structure 102, so that the overall strength of the buckle assembly 100 can be further increased, deformation of the buckle structures 101 can be effectively alleviated, and thus the yield of the subsequent buckle structures 101 assembled with the glass sheet 200 is increased.


The above is a complete description of the structure of the buckle assembly 100 provided in the embodiments of the present disclosure.


In addition, the buckle assembly 100 may be formed by an injection molding process. The specifically process may include, for example, adding an injection molding raw material into a hopper of an injection machine, heating and melting the raw material to a flowing state, pushing the material flow, by a screw or piston of the injection machine, into a prepared specific mold cavity (including a main channel, branch channels, forming cavities for the buckle structures 101, and a forming cavity for the plastic frame structure 102) through a nozzle and a pouring system of the mold, and curing and shaping the material in the specific mold cavity, so as to form the buckle assembly 100.


Here, after being put into the injection machine, the raw material may be melted into a molten state by a heating device in the injection machine, for example, by electric heating or heating with a heating oil.
