The following detailed description is made with reference to the accompanying drawings.
Example one
Referring to fig. 1, 2 and 5, a metal watch case 100 according to an embodiment of the present invention includes a plurality of metal sheets 10 and a plurality of insulating members 20, each metal sheet 10 is sequentially connected to and enclosed to form a case 1 of the metal watch case 100, a gap 11 is disposed at a connection position between any two adjacent metal sheets 10, and each insulating member 20 is respectively disposed between any two adjacent metal sheets 10 to fill the gap 11 between any two adjacent metal sheets 10.
That is, the case 1 of the metal wristwatch case 100 is composed of the plurality of metal sheets 10 and the plurality of insulating members 20. The housing 1 may be formed by integrally molding the metal sheet 10 and the insulating member 20, or the housing 1 may be formed by detachably assembling the metal sheet 10 and the insulating member 20. Preferably, the case 1 is formed by integrally molding the metal sheet 10 and the insulating member 20, so as to effectively prevent the metal sheet 10 and the insulating member 20 from moving relatively due to external force acting on the case 1 during use, and further, effectively prevent external water from entering into the metal watch case 100 from the gap 11 between any two adjacent metal sheets 10.
Among them, this metal watchcase 100 can be applied to intelligent wearing equipment, for example intelligent wrist-watch or intelligent bracelet.
Wherein, the metal watch case 100 can be used for a smart watch, and the shape of the gap 11 can be set to any practical shape, such as rectangle, S-shape, V-shape or W-shape, etc., according to the requirement. Specifically, when the metal watch case 100 is applied to a smart watch, the inside of the metal watch case 100 may be used to carry electronic components (e.g., a battery, a speaker, a circuit board, an antenna, etc.). The shape of the slit 11 may be selected to have different shapes depending on the arrangement of the electronic components provided in the metal wristwatch case 100.
In particular, the arrangement position of the antenna in the metal watch case 100 has an important influence on the shape selection of the slot 11, because the completely continuous metal sheet 10 has a shielding effect on the performance of the antenna, and the volume of the smart watch is small, and in order to realize more functions, more electronic components need to be arranged in the metal watch case 100 to realize various functions. In this case, in order to ensure the arrangement of each electronic component inside the metal watch case 100 and avoid the influence of the continuous metal sheet 10 on the performance of the antenna, the shape of the slot 11 needs to be designed into a desired shape according to the structural design of the antenna and the arrangement position of the antenna inside the metal watch case 100, for example, the slot may be set into a rectangular shape, an S shape, a V shape or a W shape, so as to reduce the influence of the metal watch case 100 on the performance of the antenna, thereby effectively ensuring the normal communication of the smart watch.
Further, the width of the gap 11 is greater than or equal to 0.8 mm, so that the gap 11 does not affect the appearance decoration effect of the metal watch case 100, and the communication signal of the intelligent wearable device using the metal watch case 100 as a shell can be ensured. It is understood that in other embodiments, the gap 11 may be formed by sequentially arranging and splicing a plurality of non-visible broken seams (not shown), and each broken seam is filled with the insulating member 20. It should be understood that the sum of the widths of the plurality of broken slits in each slit 11 should be based on the width that can be formed by the nano injection molding process, for example, may be greater than or equal to the width formed by the nano injection molding process, so as to facilitate the processing. In addition, since each broken seam is invisible to naked eyes, in fact, if the width of the broken seam is too small, the performance of the antenna may be affected, and therefore, when the width of each broken seam is set, the influence on the performance of the antenna is also ensured to be minimized, and therefore, the minimum width of each broken seam is recommended to be 0.4-0.5 mm.
Referring to fig. 2 to 4, in the present embodiment, since the two adjacent metal sheets 10 are disconnected (i.e. have the gap 11), when the metal watch case 100 is applied to a smart wearable device (e.g. a smart watch), the metal sheets 10 are used as an antenna or a part of the antenna. Specifically, the housing 1 includes at least one antenna area 14, and each antenna area 14 is disposed at an interval, that is, the metal sheets 10 constituting the housing 1 can be used as the antenna areas 14, and the whole area occupied by each metal sheet 10 can be used as the antenna area 14. For example, during design, one metal sheet 10 may be selected as the antenna region 14 according to design, two metal sheets 10 designed oppositely may also be selected as the antenna region 14, and of course, three metal sheets 10 or four metal sheets 10 may also be used, and the metal sheet 10 serving as the antenna region 14 may also be only a partial region serving as the antenna region 14 or all the regions serving as the antenna region 14, so that the smart wearable device has good antenna performance. It should be noted that by the metal sheet 10 as the antenna area 14, it is meant that the antenna feed point 12 capable of being used for electrical connection with the circuit board 13 of the smart wearable device can be arranged on the metal sheet 10, thereby forming an area different from other metal sheets 10 without the antenna. In fact, the antenna area 14 in this embodiment is only a division of one area, and is not an entity additionally provided.
The mode that adopts arbitrary one or more sheetmetal 10 as the antenna, need not additionally to set up the antenna in metal watchcase 100 inside to effectively reduce the occupation to metal watchcase 100 inner space, can satisfy the frivolous design of equipment when being favorable to being applied to intelligent wearing equipment with this metal watchcase 100.
The above-mentioned setting of the antenna feed point 12 on any one metal sheet 10 specifically means: a plurality of antenna feed points 12 are arranged on the metal sheet 10, and each antenna feed point 12 is located inside the metal watch case 100 and is respectively used for being connected with a circuit board 13 of the intelligent wearable device, so that signal receiving and transmission of the intelligent wearable device are realized.
Further, each antenna feed point 12 is close to the gap 11 between two adjacent metal sheets 10, so that the influence of the metal watch case 100 on the antenna performance can be effectively reduced, and the communication signal of the intelligent wearable device can be effectively enhanced.
Wherein the number of antenna feed points 12 provided on each antenna area 14 may be two, three, four, etc. And if the number of the antenna feed points 12 arranged on each antenna area 14 is two, the two antenna feed points 12 can be respectively arranged on two side edges of the antenna area 14, thereby effectively preventing the mutual interference between the two antennas. Similarly, if 3 or 4 antenna feed points 12 need to be provided, the installation position of the antenna feed points 12 also needs to be selected in the same consideration.
Further, when the metal watch case 100 is applied to the smart wearable device, in order to realize the electrical connection of the antenna feed point 12 on the metal watch case 100, a plurality of antenna connectors 131 may be disposed on the circuit board 13 of the smart wearable device, the antenna connectors 131 are disposed corresponding to the antenna feed point 12, and each antenna connector 131 is electrically connected to the antenna feed point 12 disposed corresponding thereto. By adopting the design, the connection convenience of the antenna feed point 12 and the circuit board 13 is facilitated.
The antenna connector 131 may be a spring, a connecting terminal, a flexible circuit board, a pogo-pin, or the like.
In this embodiment, in order to timely dissipate heat in the smart wearable device, the housing 1 may further include at least one heat dissipation area 15, and the insulation member 20 is disposed at a gap between each heat dissipation area 15 and each antenna area 14, and at the gap between each heat dissipation area 15 and each antenna area 14. That is, part of the metal sheets 10 enclosing the housing 1 may be set as the antenna region 14, and the other part may be set as the heat dissipation region 15, but when they are set, they must be ensured to be spaced apart from each other, so that the signal influence on the antenna, which may be caused by the heat dissipated at the heat dissipation region 15, can be reduced. Similarly, the concept of the heat dissipation area 15 is the same as that of the antenna area 14, and the description thereof is omitted here.
By adopting the design mode, the problem that the heat emitted by the electronic element, which is caused by the compact internal structure design of the intelligent wearable equipment, cannot be timely emitted can be effectively solved, the heat is effectively prevented from being gathered in the antenna area 14, and the stability of the antenna performance is effectively ensured.
Further, the metal wristwatch case 100 further includes at least one heat conduction member 30 and a heat collection member 40, each heat conduction member 30 is disposed corresponding to each heat dissipation area 15, that is, each heat dissipation area 15 is disposed with a heat conduction member 30, and each heat conduction member 30 is disposed inside the metal wristwatch case. Meanwhile, one end of each heat conduction member 30 is connected to the heat collecting member 40, and the other end of each heat conduction member 30 is connected to the heat dissipation area 15 corresponding thereto, that is, the other end of each heat conduction member 30 is connected to the metal sheet 10. Specifically, the heat collecting part 40 is used to collect the heat in the metal watch case 100, the heat conducting part 30 is used to conduct the heat collected by the heat collecting part 40 to the heat dissipation area 15 in time, and finally the heat in the metal watch case 100 is dissipated out in time through the heat dissipation area 15. Thereby effectively ensuring that the heat in the metal watch case 100 can be dissipated in time.
Referring to fig. 2, 5, 6 and 7, in the present embodiment, the case 1 has at least one opening, the metal watch case 100 further includes a plastic case 50, and the plastic case 50 is seamlessly connected with the case 1 to close any one opening of the case 1.
The material of the insulating member 20 of the housing 1 may be the same as the material of the plastic bottom case 50, for example, all of the insulating member 20 and the plastic bottom case 50 may be formed by integral molding, that is, when the insulating member 20 fills the gap 11, the plastic bottom case 50 closes any one opening of the housing 1. Further, the material of the metal sheet 10 constituting the housing 1 may be aluminum, magnesium, titanium alloy, stainless steel, or the like.
Any opening of the housing 1 refers to an opening of the plastic bottom case 50 that is closed by the seamless connection with the housing 1.
In the present embodiment, the plastic bottom case 50 includes a plastic inner wall 51 and a plastic outer wall 52. The plastic inner wall 51 forms an inner surface 211 of the housing 1. Specifically, since the housing 1 is used for accommodating electronic components, that is, the electronic components are disposed on the inner surface 211 of the housing 1, in order to facilitate the fixing of the electronic components inside the housing 1, a plurality of positioning structures or fixing structures, such as positioning blocks, positioning grooves or fixing blocks, for positioning or fixing the electronic components may be disposed on the inner wall 51.
Furthermore, because many electronic components need to be accommodated in the housing 1, the plastic inner wall surface 51 is used as the inner surface 211 of the housing 1, so that the characteristic that a plastic material is easy to mold can be effectively utilized, and the positioning structure or the fixing structure for positioning or fixing the electronic components is formed on the plastic inner wall surface 51, thereby reducing the processing difficulty and further reducing the processing cost.
In this embodiment, the plastic outer wall surface 52 is seamlessly bonded to the inner wall surface 16 of the housing 1. Adopt seamless laminating's mode for shell 1 can regard as the surface of metal watchcase 100, and plastic drain pan 50 can regard as the bottom surface of metal watchcase 100, thereby not only can effectively improve the outward appearance decorative effect of metal watchcase 100, makes this metal watchcase 100 have stronger outward appearance expressive force, can also guarantee that this metal watchcase 100 has good waterproof performance.
Further, since the volume of the metal wristwatch case 100 is generally small, the internal space thereof is small, and the arrangement of the electronic components is concentrated, which tends to cause a large amount of heat emitted from the electronic components inside the metal wristwatch case 100 to be concentrated inside the metal wristwatch case 100. This application adopts partly as metal watchcase 100 with shell 1 from this, can effectively utilize this characteristic that the metal heat dissipation is fast to make the inside heat of metal watchcase 100 distribute away fast through metal watchcase 1 to avoid the heat to gather in metal watchcase 100 inside and the influence electronic components's that probably leads to the condition of normal operating in a large number.
Further, the plastic bottom case 50 includes a plastic bottom 53 and an outer rim 54, the outer rim 54 is disposed around the periphery of the plastic bottom 53, and the plastic bottom 53 and the outer rim 54 are integrally formed to form an integral plastic bottom case 50. The outer wall surface of the outer edge 54 is seamlessly adhered to the inner wall surface 16 of the housing 1, and the plastic bottom 53 is used as the bottom of the metal watch case 100, so that when a user wears the intelligent wearing device with the metal watch case 100, the bottom wall of the plastic bottom 53 can be used for being adhered to the skin. By adopting the design mode, on one hand, sweat emitted by a human body cannot corrode and damage the plastic bottom shell 50; on the other hand, the plastic material has poor heat transfer performance, and the plastic bottom 53 is not easy to transfer the heat inside the metal watch case 100 to the skin of a human body, so that a good heat insulation effect can be achieved, and the wearing comfort of a user is effectively improved.
In order to further improve the wearing comfort of the user, the bottom wall of the plastic bottom 50 may be a plane, so that the plastic bottom 50 can better fit the skin of the human body.
In the seamless joint between the outer wall surface of the outer rim 54 and the inner wall surface 16 of the housing 1, the outer wall surface of the outer rim 54 can be completely jointed with the inner wall surface 16 of the entire housing 1, that is, the height of the outer rim 54 is the same as the height of the housing 1. At this time, if the metal watch case 100 is formed by injection molding the plastic bottom case 50 and the housing 1 through an integral molding method (e.g., nano injection molding process), after the molding, a material of the outer edge 54 of the plastic bottom case 50 needs to be removed by a material removing method (e.g., cutting off material, scraping off material) inside the metal watch case 100 to form the installation position of the antenna feed point 12. Of course, in other embodiments, the attaching height between the outer wall surface of the outer rim 54 and the inner wall surface 16 of the housing 1 may only occupy a part of the height of the inner wall surface 16 of the housing 1, in this case, the position where the antenna feed point 12 is disposed may be located at a non-attaching portion or at an attaching portion, and if the antenna feed point 12 is located at the attaching portion, the position where the antenna feed point 12 is disposed needs to be formed by removing a plastic material, and this choice is related to the position where the antenna is disposed.
In the present embodiment, the metal watch case 100 is designed to be waterproof with respect to the seamless connection between the plastic case 50 and the case 1, so that the joint between the plastic case 50 and the case 1 has excellent waterproof performance. This metal watchcase 100 can be applied to and dress equipment (for example intelligent wrist-watch or intelligent bracelet) to the higher intelligence of waterproof performance demand to can prevent effectively that water from intelligent wearing equipment outside (promptly, metal watchcase 100 is outside) from entering inside (promptly, inside metal watchcase 100), and then make the user also can realize this intelligence wearing equipment's normal use in the water environment.
Furthermore, the seamless joint between the plastic outer wall surface 52 and the inner wall surface 16 of the housing 1 can be achieved by nano injection molding, hot melting, gluing, ultrasonic wave, etc., so that the plastic outer wall surface 52 and the housing 1 can be tightly jointed, and excellent waterproof performance is ensured. Preferably, the plastic outer wall 52 and the housing 1 are attached together by nano injection molding, and in the nano injection molding process, the injection temperature is 195-385 ℃, the injection pressure is 65-155Mpa, and the mold temperature is 20-175 ℃.
In this embodiment, a first connecting step 61 may be formed at a connection portion of the bottom case 50 and the housing 1, a second connecting step 62 may be disposed on the housing 1 corresponding to the first connecting step 61, and the second connecting step 62 is attached to the first connecting step 61, so as to achieve a seamless connection between the bottom case 50 and the housing 1. Specifically, the first connecting step 62 can be a part of the plastic bottom case 50, or can be formed on the plastic bottom case 50 by being integrally formed with the plastic bottom case 50, and the material of the first connecting step 61 is also plastic. Similarly, the second connecting step 62 may be a part of the housing 1, or may be formed on the housing 1 by being integrally formed with the housing 1, and the material of the second connecting step 62 is the same as the metal sheet 10 constituting the housing 1. The adoption sets up the laminating mode that first connection step 61 and second are connected step 62 respectively at plastic drain pan 50 and shell 1, can effectively increase plastic drain pan 50 and shell 1's laminating area to can effectively lengthen the inside distance that enters into plastic drain pan 50 from the junction of shell 1 and plastic drain pan 50 of outside water, and then effectively strengthen this metal watch case 100's water-proof effects.
Wherein the external water refers to water outside the metal wristwatch case 100.
Further, in order to effectively ensure the waterproof performance of the joint of the plastic bottom case 50 and the housing 1, a waterproof joint surface is formed at the joint of the first connecting step 61 and the second connecting step 62, and a projection of the waterproof joint surface along the longitudinal section direction of the plastic bottom case 50 forms a waterproof path L. Specifically, referring to fig. 7 to 9, the waterproof path L will be described in detail with reference to the drawings.
In the present embodiment, the first connecting step 61 may be composed of one or more steps, and similarly, the second connecting step 62 may also be composed of one or more steps. That is, the waterproof path L can be divided into continuous multi-stage paths, which are respectively denoted as L1, L2, L3, L4, … …, and Ln, i.e., L — L1+ L2+ L3+ L4+ … … + Ln. Specifically, the first connecting step 61 and the second connecting step 62 are each composed of three steps, and at this time, the waterproof path L is L1+ L2+ L3 (as shown in fig. 9).
The longer the waterproof path L, the greater the water pressure required for external water to enter the plastic case 50 from the joint of the case 1 and the plastic case 50, that is, the longer the waterproof path L, the better the waterproof performance of the metal watch case 100.
Alternatively, when the inner wall surface 16 of the housing 1 and the outer plastic wall surface 52 are completely and seamlessly adhered, the waterproof path L only needs to be designed to have a reasonable length (as shown in fig. 8).
Alternatively, when inner wall surface 16 of case 1 and plastic outer wall surface 52 are only partially attached without seams, in order to ensure the waterproof effect of metal wristwatch case 100, the length of waterproof path L must be greater than the distance La by which external water penetrates into plastic bottom case 50 from the junction of case 1 and plastic bottom case 50, i.e., L > La. In this way, even in the case where the first joining surface 41 and the second joining surface 42 cannot be completely joined together seamlessly, it is possible to surely prevent the entry of external water into the metal wristwatch case 100 (see fig. 9).
In the present embodiment, the waterproof combination surface includes at least one first combination surface 41 located between the outer wall surface 17 of the housing 1 and the outer wall surface 52 of the plastic bottom case 50 and at least one second combination surface 42 located between the inner wall surface 16 of the housing 1 and the inner wall surface 51 of the plastic bottom case 50. The first combining surface 41 and the second combining surface 42 are both surfaces of the first connecting step 61 facing the second connecting step 62.
Further, the position of the first coupling surface 41 is a water inlet position 411, and the position of the second coupling surface 42 is a waterproof position 421. When the inside of the metal wristwatch case 100 leaks, the external water penetrates into the first joining surface 41 through the water inlet 411, then penetrates into the second joining surface 42, and leaks into the inside of the metal wristwatch case 100 from the waterproof position 421.
Further, referring to fig. 8 and 10, the number of the first combining surfaces 41 and the second combining surfaces 42 may be one, two, or more. Specifically, when the outer edge 54 of the plastic bottom shell 50 does not completely cover the inner wall surface 16 of the housing 1, there is one first combining surface 41 and one second combining surface 42, and at this time, external water can only infiltrate from the water inlet position 411 of the first combining surface 41; when the outer edge 54 of the plastic bottom shell 50 completely covers the inner wall surface 16 of the housing 1, two first combining surfaces 41 and two second combining surfaces 42 are provided, the two first connecting surfaces 41 are respectively positioned at a first water inlet position 411a and a second water inlet position 411b, and the water inlet direction of the first water inlet location 411a is perpendicular to the water inlet direction of the second water inlet location 411b, when the number of the first coupling surfaces 41 is two, the external water can be introduced from the first water inlet 411a and the second water inlet 411b, respectively, and at this time, in order to improve the waterproof performance of the metal wristwatch case 100, the design should be such that the waterproof path from the first water inlet 411a to the second combining surface 42 is greater than the distance from the external water entering from the first water inlet 411a to the second combining surface 42, and a waterproof path from the second water inlet position 411b to the second combining surface 42 is greater than a distance by which external water entering from the second water inlet position 411b permeates to the second combining surface 42.
In addition, since the number of the first combining surface 41, the second combining surface 42 and the water inlet position 411 is the same, compared with a case where the first combining surface 41 and the second combining surface 42 are both one, the case where the first combining surface 41 and the second combining surface 42 are both two, and the water inlet position 411 is increased, which results in an increase in the probability of external water penetrating into the metal wristwatch case 100, and therefore, a case where the first combining surface 41 and the second combining surface 42 are both one is preferable.
Preferably, in order to enhance the waterproof effect of the metal wristwatch case 100, a dispensing groove 43 may be provided on the waterproof bonding surface, and a waterproof glue 431 may be provided on the dispensing groove 43.
As an alternative embodiment, when there are a plurality of water inlet positions 411, taking two water inlet positions 411 as an example, as shown in fig. 9, when the distance that the external water enters the plastic case 50 from the first water inlet position 411a is less than the distance that the external water enters the plastic case 50 from the second water inlet position 411b, a dispensing groove 43 may be disposed on the second combining surface 42 adjacent to the first water inlet position 411a, and a waterproof glue 431 is disposed in the dispensing groove 43, so that the waterproof glue 431 can be used to completely adhere the casing 1 and the plastic case 50, thereby isolating the possibility that the external water penetrates into the metal watch case 100 from the second combining surface 42.
Specifically, from the first water inlet position 411a to the first waterproof position 421a (i.e., one of the second joint surfaces 42) is a first waterproof path 71, and the first waterproof path 71 is divided into two sections, including a first section 71a and a second section 71 b. From the second water inlet position 411b to the second waterproof position 421b (i.e., the other second joint surface 42) is a second waterproof path 72, and the second waterproof path 72 is divided into three sections including a third section 72a, a fourth section 72b, and a fifth section 72 c. The length of the first waterproof path 71 is smaller than that of the second waterproof path 72, the path directions of the first section 71a and the fourth section 72b are both perpendicular to the bottom of the plastic bottom case 50, and the path length of the first section 71a is shorter than that of the fourth section 72b, so when external water seeps from the first water inlet position 411a and the second water inlet position 411b simultaneously, the external water is easier to seep into the connecting position of the first section 71a and the second section 71b than the connecting position of the fourth section 72b and the fifth section 72 c. Meanwhile, since the total length of the first waterproof path 71 is less than that of the second waterproof path 72, in order to prevent external water from infiltrating from the first water inlet position 411a to the first waterproof position 421a, a dispensing groove 43 may be provided on the second joint surface 42 of the second section 71b, and a waterproof adhesive 431 may be provided in the dispensing groove 43, and the waterproof adhesive 431 is only located at the first waterproof position 421a, and the waterproof adhesive 431 may not be provided at the second waterproof position 421 b.
Further, the waterproof glue 431 may be provided at the first waterproof position 421a and the second waterproof position 421b at the same time, and at this time, no matter the external water permeates from the first water inlet position 411a or the second water inlet position 411b, the waterproof glue 431 cannot further permeate at the first waterproof position 421a and the second waterproof position 421b due to the waterproof function of the waterproof glue 431, so that the waterproof performance of the metal wristwatch case 100 is further ensured.
As another alternative, when there is only one water inlet 411, the second combining surface 42 may be provided with a dispensing groove 43, and the dispensing groove 43 may be provided with a waterproof glue 431 to completely fill the second combining surface 42.
In this embodiment, referring to fig. 2 and 3, the metal watch case 100 further includes a watch ear 80, the watch ear 80 includes a first portion 81 and a second portion 82 connected to the first portion 81, the first portion 81 is integrally formed on the outer wall surface 17 of the case 1, the second portion 82 is integrally formed on the outer wall surface 52 of the plastic bottom case 50, a first curved surface (not labeled) is formed at a connection portion of the first portion 81 and the case 1, and a curvature of the first curved surface is greater than or equal to 2 mm; the joint of the second portion 82 and the plastic bottom case 50 forms a second curved surface (not labeled), and the curvature of the second curved surface is greater than or equal to 2 mm.
Further, the material of the first portion 81 is a metal material, and the material of the second portion 82 is a plastic material. The curvature range of the first curved surface is favorable for ensuring the appearance effect of the surface lug 80 and facilitating the processing of the curved surface of the first part 81 by a machine tool.
