Description

Shell with mark piece and electronic equipment

Technical Field

The present application relates to the field of assembly structures, and in particular, to a housing with a marker and an electronic device.

Background

Various marks (such as logos, word prints, trademarks and the like) are usually provided on the appearance surface of the shell, and the current method for providing the marks on the appearance surface of the shell includes directly engraving the marks on the appearance surface of the shell by using a laser engraving or silk screen printing process. However, the mark provided in this way has poor durability and is prone to fogging, wear, and the like after long-term use.

Therefore, in order to improve the durability of the mark on the appearance surface of the shell, the mark piece is usually independently manufactured at present, the groove with the same shape of the mark piece is arranged on the appearance surface of the shell, and the independently manufactured mark piece is fixed in the corresponding groove in a dispensing manner, so that the gap between the mark piece and the groove is filled with glue, and the mark piece is stably fixed in the groove and is not easy to fall off.

However, in order to improve the appearance of the embedded marker, the gap between the side wall of the marker and the groove needs to be reduced, and the outer surface of the marker and the outer surface of the shell need to be kept in a flush state, so that the gap between the bottom surface of the marker and the groove cannot be too large, and the outer surface of the marker is prevented from being sunk into the groove due to shrinkage after glue curing, and the appearance is not influenced.

Therefore, when the size of the marker is reduced, the clearance between the groove and the marker is further reduced, and even if the machining of the marker and the groove is within the error range, however, the volume of the space in the gap between the groove and the marking member varies considerably after assembly, resulting in large fluctuations in the amount of glue required to fill the gap, and errors in the amount of glue applied during dispensing, meanwhile, in order to ensure that the mark piece can be firmly adhered in the groove and the coating amount of the glue is easy to be excessive, thereby causing the excessive glue to overflow from the inside of the groove to the outside of the housing when the marker is adhesively fixed in the groove, namely, the glue overflow phenomenon is generated, so that the process of removing the appearance residual glue is additionally added, the production efficiency is influenced, meanwhile, the glue removing process easily damages the appearance surface of the shell, and the appearance delicacy and the attractiveness of the shell are affected.

Make the mark piece through the mode of gluing with protruding fixed in-process, when the glue that flows is excessive, the glue that flows can cover the mark piece towards bellied surface, and under the effect of extrusion force and the self gravity of the glue that flows when the mark piece installation, the glue that flows can flow downwards along bellied lateral wall face. Thereby avoiding the excessive flowing glue from overflowing to the outer surface of the shell to generate the glue overflowing phenomenon. In addition, during dispensing, the glue overflowing situation is not needed to be worried about, so that the using range of the coating flowing glue is wider, the precision requirement on the coating amount of the flowing glue is low, and the cost of coating flowing glue equipment is reduced.

In some embodiments, a width of a first gap between a sidewall surface of at least one protrusion and a corresponding wall surface of the through-hole is greater than a width of a second gap between a sidewall surface of the flag and a wall surface of the through-hole. In the process of bonding the marking piece and the flowing glue, when the marking piece extrudes the flowing glue, because the width of the first gap is greater than that of the second gap, the resistance of the flowing glue in the first gap is less than that of the second gap, and simultaneously, under the action of the extruding force of the marking piece and the self gravity of the flowing glue, the flowing glue flows towards the first gap, so that the flowing glue is prevented from overflowing to the outer surface of the shell from the second gap, and the subsequent production process is influenced.

In some embodiments, the wall surface of the through hole is stepped in the height direction of the through hole, and the wall surface of the through hole facing the convex sidewall surface is recessed toward the inside of the structural member to increase the width of the first gap.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic top view of a housing according to an embodiment of the present disclosure, and fig. 2 is a schematic cross-sectional view of the housing in fig. 1 along a direction a-a.

As shown in fig. 1 and 2, the embodiment of the present application provides a housing 1 having a marker 20, including a structural member 10, a plurality of markers 20, and a support plate 30, wherein the structural member 10 constitutes a main body portion of the housing 1, and has a certain rigidity and thickness for supporting and protecting. In some embodiments, the structural member 10 may be a housing portion of an electronic device, a mechanical device, or a packaging device, among others. In some embodiments, the structural member 10 may be made of any sufficiently rigid material, such as plastic, metal, etc.

The structural member 10 has opposite inner and outer surfaces a, b and a plurality of through holes 11 passing through the inner and outer surfaces a, b. The plurality of through holes 11 are arranged in one-to-one correspondence with the plurality of markers 20, and the shape of any through hole 11 in the plurality of through holes 11 is matched with the shape of the corresponding marker 20, that is, the shape of any through hole 11 in the through direction is the same as the shape of the corresponding marker 20 in the thickness direction, so that the corresponding marker 20 can be inserted into the through hole 11 from the thickness direction. The number of the plurality of through holes 11 is the same as the number of the plurality of marker members 20. The outer surface b of the structural member 10 is disposed toward the outside of the housing 1, and when the plurality of markers 20 are inserted into the plurality of through holes 11, the outer surface b of the structural member 10 may serve as a background surface for displaying the plurality of markers 20. And the texture of the structural member 10 and the texture of the mark members 20 are different, so that the plurality of mark members 20 can display texture different from the texture of the outer surface b of the structural member 10 (for example, the structural member 10 is made of a material with frosted texture, and the mark members 20 are made of a material with mirror effect), thereby improving the aesthetic property of the mark members 20 when displayed outside the casing 1. In other alternative embodiments, the materials used for the structural member 10 and the flag 20 may be the same.

In some embodiments, the structural member 10 and the marker 20 are different colors, making the marker 20 more visible on the exterior surface b of the structural member 10. In other alternative embodiments, the colors used for the structural member 10 and the indicia member 20 may be the same.

The housing 1 has a plurality of marker pieces 20, and different marker pieces 20 may be formed in the same shape or in different shapes. As shown in fig. 1, in one embodiment, the plurality of markers 20 are respectively shaped like letters "L", "O", "G", and "O", and the four markers 20 are arranged such that the four markers 20 are inserted into the corresponding through holes 11, thereby forming a word "LOGO" on the outer surface b of the structural member 10. The surface of the marker 20 that can be observed after being inserted into the through hole 11 is a decoration surface c, and the decoration surface c of the marker 20 and the outer surface b of the structural member 10 together form an appearance surface of the housing 1.

As will be understood by those skilled in the art, the marker 20 is used to display a specific character or graphic on the outer surface of the housing 1. In other alternative embodiments, the number of the markers 20 is not limited to four, and may be one, or 2, 3, 5, or more than 5. Meanwhile, in other alternative embodiments, the shape of the decorative surface c of the marker 20 is not limited to the above-mentioned letters, but may be other letters, numbers, characters, or figures, such as trademarks, logos, decorative patterns, and written instructions. In other alternative embodiments, the number of the marking members 20 is one, and since the number of the through holes 11 corresponds to the number of the marking members 20, the number of the through holes 11 may also be one.

The marking member 20 is inserted into the through hole 11 from the outer surface b of the structural member 10, and the decorative surface c of the marking member 20 is flush with the outer surface b of the structural member 10, so that the appearance surface of the housing 1 displaying the decorative surface c of the marking member 20 can be kept flat and has good aesthetic property. In other alternative embodiments, the decorative surface c of the marker 20 and the outer surface b of the structural member 10 may also be disposed non-flush, such that the decorative surface c of the marker 20 may protrude or be recessed from the outer surface b of the structural member 10, such that the decorative surface c of the marker 20 may be used to display a three-dimensional graphic, such as a relief graphic, a solid graphic, etc.

In some embodiments, the plurality of marking members 20 are separated from each other, so that each of the plurality of marking members 20 can be individually manufactured and processed, and can have a high processing precision, so that the marking members 20 can have complicated figures, characters, and the like. For example, the marker 20 may be formed by stamping. So that the width d3 of the flag 20 may be 0.6 mm or less. Wherein the width d3 of the marker 20 is the width of the character stroke when the marker 20 is a character, and the width d3 of the marker 20 is the width of the line constituting the figure when the marker 20 is a figure.

Referring to fig. 3a to 4, fig. 3a is a schematic structural diagram of a support plate of a housing according to an embodiment of the present disclosure, fig. 3b is a schematic structural diagram of the support plate provided with a sealing connection portion in fig. 3a, and fig. 4 is a schematic structural diagram of a top view of the housing without a marker according to the embodiment of the present disclosure. As shown in fig. 3a to 4, and as will be understood in conjunction with fig. 2, the support plate 30 is fixedly provided to the inner surface a of the structural member 10 and covers the plurality of through holes 11 at the same time. The support plate 30 has at least one protrusion 31 extending toward the inside of the through-hole 11 at a position facing each through-hole 11. For example: in fig. 4, the support plate 30 is provided with one protrusion 31 extending into the through hole 11 having the letter "L", and the support plate 30 is provided with two protrusions 31 extending into the single through hole 11 having the letter "O". In other alternative embodiments, more than two protrusions 31 may be provided extending from the supporting plate 30 towards the same through hole 11. At least one protrusion 31 extends into its corresponding through hole 11, so that the marking member 20 can be inserted into the through hole 11 and adhesively fixed with the at least one protrusion 31 in the through hole 11.

In some embodiments, the at least one protrusion 31 and the support plate 30 may be integrally formed. In other alternative embodiments, the supporting plate 30 and the at least one protrusion 31 may be provided in a separate manner, that is, at least one protrusion 31 is fixedly provided on the supporting plate 30.

Referring to fig. 5, fig. 5 is a schematic cross-sectional view of a portion of the housing in fig. 2. As shown in fig. 5 and understood in conjunction with fig. 3a to 4, during the assembly process, the support plate 30 is fixedly disposed on the inner surface a of the structural member 10 and covers the plurality of through holes 11 at the same time. The surface of all the protrusions 31 facing away from the support plate 30 and extending from the outer surface b of the structural member 10 into the through hole 11 is coated with a flowable adhesive, and then the marking member 20 corresponding to the through hole 11 is inserted into the through hole 11 until the decorative surface c of the marking member 20 is flush with the outer surface b of the structural member 10 and adhesively fixed. In this process, the surface of the flag 20 facing the projection 31 gradually contacts and presses the flowable adhesive, which flows all around to cover the surface of the flag 20 facing the projection 31 during the pressing process. When the amount of flow glue applied is correct, the flow glue covers the upper surfaces of all the protrusions 31 in the through hole 11 and is completely adhesively fixed to the surface of the marker 20 facing away from the decorative surface c.

Referring to fig. 6a and 6b, fig. 6a and 6b are schematic cross-sectional views of a portion of a housing when the amount of the flowable rubber is excessive according to another embodiment of the present application. When the amount of the flowable adhesive applied to the projection 31 is excessive, the flowable adhesive will overflow from the edge of the upper surface of the projection 31, and at this time, the flowable adhesive will flow in the direction toward the support plate 30 along the side wall surface of the projection 31 under the continuous pressing force of the marker 20 and the gravity of the flowable adhesive itself. Thereby effectively avoiding the flowing glue from overflowing to the appearance surface of the shell 1. Therefore, the glue removing process for the appearance surface of the shell 1 is not required to be added, the production process of the shell 1 is simplified, the damage of the glue removing process to the appearance surface of the shell 1 is avoided, and the delicacy of the appearance surface of the shell 1 is improved. When the coating is excessive in protruding 31 mobile glue simultaneously, excessive mobile glue can deviate from the surface of decorative cover c with mark piece 20 on the one hand and contact the bonding completely, avoids leading to bonding fastness to reduce because of mobile glue and mark piece 20's bonding area undersize, and on the other hand mobile glue overflows from protruding 31's upper surface edge to can wrap up protruding 31's lateral wall face and bond with protruding 31's lateral wall face, increased mobile glue and protruding 31's bonding area. So that the flowable adhesive can firmly adhesively fix the marker 20 to the protrusion 31.

Further, as shown in fig. 6a and 6b, there are a first gap 51 between the side wall surface of the projection 31 and the wall surface of the through hole 11, a second gap 52 between the side wall surface of the flag 20 and the wall surface of the through hole 11, and a width d1 of the first gap 51 is larger than a width d2 of the second gap 52. Here, the width d1 of the first gap 51 is the distance between the side wall surface of the protrusion 31 and the wall surface of the through hole 11, and the width d2 of the second gap 52 is the distance between the side wall surface of the flag 20 and the wall surface of the through hole 11. When the flowable adhesive overflows from the upper surface edge of the projection 31 during the insertion of the marker 20 into the through hole 11, since the width d1 of the first gap 51 is greater than the width d2 of the second gap 52, the resistance to the flow of the flowable adhesive into the first gap 51 is smaller than the resistance to the flow of the flowable adhesive into the second gap 52, and the flowable adhesive is also caused to flow downward into the first gap 51 by its own weight. So that the excessive flowing glue overflows into the first gap 51 without overflowing from the second gap 52 to the appearance surface of the housing 1.

In order to ensure the assembling precision between the plurality of marking elements 20 and the plurality of through holes 11 and make the plurality of marking elements 20 more beautiful when being arranged in the plurality of through holes 11 of the structural member 10, the plurality of marking elements 20 and the plurality of through holes 11 are respectively and independently processed, and the plurality of marking elements 20 are assembled one by one, namely, the marking elements 20 and the through holes 11 which are matched with each other are separately processed and assembled. Such that the width d2 of the second gap 52 between the side wall surface of each marker 20 and the wall surface of its corresponding through hole 11 can be smaller or much smaller than the width d3 of the marker 20, for example, when the width d3 of the marker 20 is 0.6 mm, the width d2 of the second gap 52 can be less than or equal to 0.05 mm.

In addition, since the width d1 of the first gap 51 is greater than the width d2 of the second gap 52, the difficulty in assembling the protrusion 31 with the through hole 11 is reduced, and the protrusion 31 is disposed inside the through hole 11, the requirement for the shape accuracy of the protrusion 31 is low, thereby reducing the difficulty in disposing the protrusion 31 on the support plate 30. In some embodiments, when the protrusion 31 is provided as an integral part of the support plate 30, the protrusion 31 may be formed by a material removal process (e.g., computer numerical control or CNC tool) of the support plate 30.

In some embodiments, the inner wall of the through hole 11 may be stepped, and the inner wall of the through hole 11 facing the side wall surface of the protrusion 31 is recessed toward the inside of the structural member 10 to increase the width d1 of the first gap 51. Therefore, the resistance of the flowing glue flowing into the first gap 51 is further reduced, the flowing glue can easily flow into the first gap 51, meanwhile, the space in the first gap 51 is increased, more overflowing flowing glue can be contained in the first gap 51, and the phenomenon that the first gap 51 is filled with the flowing glue is avoided, so that the excessive flowing glue overflows to the appearance surface of the shell 1 from the second gap 52 is avoided.

In other alternative embodiments, the inner wall of the through hole 11 may be non-stepped, and the distance between the side wall surface of the protrusion 31 and the wall surface of the through hole 11 is increased by reducing the size of the protrusion 31 in the circumferential direction, that is, by increasing the width d1 of the first gap 51. Thereby enhancing the effect of preventing the glue overflow.

In order to ensure that the flowable glue can smoothly overflow into the first gap 51, in some embodiments, the width d1 of the first gap 51 is more than twice the width d2 of the second gap 52, for example, when the width d2 of the second gap 52 is 0.05 mm, the width d1 of the first gap 51 may be 0.1 to 0.15 mm.

Referring to fig. 7a and 7b, fig. 7a and 7b are schematic cross-sectional views of a housing when the amount of the flowable rubber is excessive according to another embodiment of the present application. As will be understood in connection with fig. 2 and 3b, the support plate 30 has a first surface m and a second surface n facing away from the first surface m, the first surface m of the support plate 30 being arranged towards the inner surface a of the structural member 10; the edge position of the first surface m of the support plate 30 is hermetically connected with the inner surface a of the structural member 10, and an excessive space 40 communicating with the through hole 11 is formed between the first surface m of the support plate 30 and the inner surface a of the structural member 10. When the space in the first gap 51 cannot fully accommodate the excess flow glue. The flowing glue flowing into the first gap 51 can flow into the glue overflowing space 40, so that the accommodating amount of the overflowing flowing glue is increased, and the phenomenon that the flowing glue overflows to the appearance surface of the shell 1 from the second gap 52 due to the fact that the flowing glue fills the first gap 51 fully is avoided.

In some embodiments, in order to ensure that the flowing paste can flow to the paste overflowing space 40, the height d5 of the paste overflowing space 40 where the paste overflowing space 40 communicates with the through hole 11 is greater than the width d2 of the second gap 52, for example, when the width d3 of the marker 20 is 0.6 mm, and the width d2 of the second gap 52 is 0.05 mm, the height d5 of the paste overflowing space 40 is 0.15 mm to 0.2 mm.

In some embodiments, the edge position of the first surface m of the supporting plate 30 is fixed to the inner surface a of the structural member 10 by a sealing connection portion 33, wherein the sealing connection portion 33 may be a material having a sealing connection function, such as liquid glue, fixing glue, or back glue. So that the sealing connection part 33 can sealingly connect the first surface m of the support plate 30 with the inner surface a of the structural member 10. In the assembling process, the sealing connection portion 33 is coated around the plurality of protrusions 31 at the edge position of the first surface m of the support plate 30, and then the first surface m of the support plate 30 is adhered and fixed to the inner surface a of the structural member 10, so that the portion of the first surface m of the support plate 30, where the protrusions 31 are arranged, extends into the through hole 11 corresponding to the protrusions 31. When the sealing connection portion 33 is bonded firmly, the sealing connection portion 33 forms a circumferential sealing ring around the plurality of protrusions 31, and a gap space is formed between the first surface m of the support plate 30 and the inner surface a of the structural member 10 under the support of the thickness of the sealing connection portion 33 itself, so that an adhesive overflow space 40 enclosed around the circumference of the plurality of protrusions 31 is formed. At this time, the flash space 40 is isolated from the space where the second surface n of the support plate 30 is located. So that the flowing glue can only flow in the glue overflowing space 40 and the flowing glue in the glue overflowing space 40 is prevented from entering the space where the second surface n of the supporting plate 30 is located. When the structural member 10 is a housing part of an electronic device, a mechanical device, a packaging device, or the like, the second surface n of the support plate 30 is located in an internal space surrounded by the housing.

In order to reduce the occupation of the internal space of the housing 1, when the supporting plate 30 is made of a high-strength metal such as steel or aluminum alloy, the thickness d4 of the supporting plate 30 may be as thin as 0.2 to 0.3 mm.

Referring to fig. 8 to 10, fig. 8 is a schematic top view of the housing of fig. 1 within a dashed line frame L, fig. 9 is a schematic top view of the housing of fig. 4 within a dashed line frame P, and fig. 10 is a schematic cross-sectional view of the housing of fig. 8 along a direction B-B. As shown in fig. 8 to 10, in some embodiments, the supporting plate 30 has a protrusion 31 extending into the through hole 11 at a position facing the single through hole 11, as shown in fig. 9, the protrusion 31 is disposed in an "L" shape, and the shape of the through hole 11 is adapted, and in other alternative embodiments, the supporting plate 30 may have a plurality of mutually spaced protrusions 31 extending into the through hole 11 at a position facing the single through hole 11. The surface of the protrusion 31 in the single through hole 11, which faces away from the supporting plate 30, is provided with a plurality of supporting protrusions 311, the plurality of supporting protrusions 311 are used for supporting the marker 20, so that a glue containing space 312 for containing the flowing glue is formed between the surface of the protrusion 31, which faces away from the supporting plate 30, and the marker 20, and the glue containing space 312 is filled with the glue part 32 formed by curing the flowing glue. Thereby adhesively securing the flag member 20 to the surface of the boss 31 facing away from the support plate 30 and preventing the flag member 20 from falling off the boss 31. When the marking member 20 is adhered and fixed on the surface of the protrusion 31 departing from the supporting plate 30, the plurality of supporting protrusions 311 can directly abut against the supporting marking member 20, so that the marking member 20 can be kept stable or the decorative surface c of the marking member 20 and the outer surface b of the structural member 10 can be kept flush, the appearance surface of the shell 1 has high flatness, and the precision of the appearance surface of the shell 1 is improved.

Meanwhile, when the flowing glue shrinks or reduces in volume during curing or drying, the marking member 20 will not deviate or have an unfair surface with respect to the structural member 10 under the supporting action of the plurality of supporting protrusions 311, which affects the aesthetic property of the structural member 10 after the outer surface b is matched with the marking member 20.

In addition, because the glue containing space 312 is open in the circumference, can take place to shrink or reduce the volume in circumference when the mobile glue solidifies for the thickness of the colloidal part 32 after the mobile glue solidifies can remain unchanged, thereby when bonding between arch 31 and marker 20, colloidal part 32 can fully contact with arch 31 and marker 20, keeps the biggest bonding area, promotes the bonding steadiness.

Further, a plurality of supporting protrusions 311 are distributed at the ends and the turns of the protrusions 31. Thereby improving the stability of the plurality of support protrusions 311 to support the marker 20. It will be appreciated by those skilled in the art that the plurality of supporting protrusions 311 serve to support the marker 20 stably, and thus in other alternative embodiments, the plurality of supporting protrusions 311 may be uniformly or randomly distributed on the upper surface of the protrusion 31.

In other alternative embodiments, the surface of the projection 31 facing away from the support plate 30 may also be provided with only a single support projection 311, for example in fig. 3a, only a single support projection 311 is provided in the two projections 31 for supporting the marking member 20 with the decorative surface c "G". In other alternative embodiments, the surface of the protrusion 31 facing away from the supporting plate 30 may also be provided without the supporting protrusion 311, for example, in fig. 3a, no supporting protrusion 311 is provided in the two protrusions 31 for supporting the marking piece 20 with the decoration surface c being "O".
