Description
Technical Field
The present application relates to the field of communications devices, and in particular, to a housing, an antenna device, a mobile terminal, and a method for processing a housing.
Background
Along with the development of technology and the increasing requirements of users on the signal and appearance quality of electronic products, many electronic products with antennas such as mobile phones on the market currently use metal as appearance shells (including side surfaces, back covers and the like) so as to meet the texture appearance. As is well known, metal is a signal shielding material, and an all-metal housing, while aesthetically pleasing, can create some barrier to the radio frequency signals of the antenna.
In the prior art, gaps are cut on a metal shell through a numerical control machine tool to form a clearance area, and the machined clearance area is often large due to the limitation of a cutter or a control mode of the numerical control machine tool, so that the structural strength of the shell is easily insufficient.
Disclosure of Invention
The application aims to provide a shell with high structural strength, an antenna device, a mobile terminal and a shell processing method.
In order to achieve the above object, the present application adopts the following technical scheme:
in a first aspect, a housing is provided, which has at least two conductive portions and at least one insulating portion for isolating the at least two conductive portions, the insulating portion has a micro-slit tape and two slits respectively connected to two ends of the micro-slit tape, the micro-slit tape has a plurality of micro-slits, each micro-slit is communicated to the two slits, and insulating materials are filled in the plurality of micro-slits and the two slits.
In a second aspect, an antenna device is provided, which includes a radio frequency transceiver circuit, a matching circuit, and the housing, where the radio frequency transceiver circuit is electrically connected to the conductive portion through the matching circuit.
In a third aspect, a mobile terminal is provided, which includes an antenna assembly and the housing, where the antenna assembly is located inside the housing.
In a fourth aspect, there is also provided a method for processing a housing, including:
providing a shell substrate;
forming a micro-slit tape on the shell base material in a laser cutting mode, wherein the micro-slit tape is provided with a plurality of micro-slits;
forming two gaps on the shell base material in a mechanical cutting mode, wherein the two gaps are connected to two ends of the micro-gap belt, and each micro-gap is communicated with the two gaps; and
and filling insulating materials in the micro-gaps and the two gaps to form the shell.
Compared with the prior art, the application has the following beneficial effects:
the insulation part of the shell adopts a gap-micro gap belt-gap mixed structure, and compared with a pure gap structure in the prior art, the structural strength of the shell is enhanced, so that the structural strength of the shell is higher. The width of each micro seam in the micro seam belt is very small, so that consumers are not easy to pay attention to the appearance, the integrity of the appearance of the shell and the appearance of the mobile terminal is guaranteed, and meanwhile, the appearance of the shell and the appearance of the mobile terminal can be more ornamental through the design of the shape of the slit.
Because the micro-slots and the two slots of the micro-slot belt are filled with insulating materials, the micro-slot belt and the two micro-slots can be antenna clearance areas for the antenna radio frequency signals to pass through. Because of the different shapes (and areas), the micro-slot strip and the two slots can also become antenna headroom areas of different antennas, so that the functions of the mobile terminal applying the shell are more diversified.

Referring to fig. 1 to 5, an embodiment of the present application provides a mobile terminal 100, where the mobile terminal 100 includes a housing 1 and a terminal body located inside the housing 1. The terminal body comprises a main board, a display, a battery and the like. The mobile terminal 100 may be an electronic device such as a mobile phone, a notebook computer, or a tablet computer.
The housing 1 has at least two conductive portions 11 and at least one insulating portion 12 that interrupts the at least two conductive portions 11. The conductive portion 11 is made of a conductive material, such as metal. The insulating part 12 has a micro-slit tape 13 and two slits 14 respectively connected to both ends of the micro-slit tape 13. That is, the micro slit tape 13 is connected between the two slits 14. The micro-slit tape 13 has a plurality of micro-slits 131, and each of the micro-slits 131 is connected to the two slits 14. The micro-slits 131 and the two slits 14 are filled with insulating material. At this time, the insulating portion 12 can smoothly interrupt the electrical connection between the at least two conductive portions 11.
In this embodiment, the insulation portion 12 adopts a mixed structure of the slit 14-micro slit tape 13-slit 14, which enhances the structural strength of the housing 1 compared with the pure slit structure in the prior art, so that the structural strength of the housing 1 is higher. Since the width h of each micro slit 131 in the micro slit tape 13 is small, it is not easy to draw attention of consumers in appearance, so it is advantageous to ensure the integrity of the appearance of the housing 1 and the mobile terminal 100, and the appearance of the housing 1 and the mobile terminal 100 can be more ornamental by designing the shape of the slit 14.
It can be appreciated that, since the plurality of micro-slots 131 and the two slots 14 of the micro-slot tape 13 are filled with insulating material, the micro-slot tape 13 and the two micro-slots 131 can each be an antenna clearance area for the rf signal to pass through. The micro-slot 13 and the two slots 14 can also be antenna headroom areas of different antennas due to the different shapes (and areas), so that the functions of the mobile terminal 100 to which the housing 1 is applied are more diversified.
Specifically: as shown in fig. 4, the terminal body of the mobile terminal 100 further includes an antenna assembly. The antenna assembly comprises a first antenna 3, a second antenna 4 and a third antenna 5.
The first antenna 3 includes a first radio frequency transceiver circuit 31, a first radiator 32, and a first matching circuit 33 connected between the first radio frequency transceiver circuit 31 and the first radiator 32. The first radiator 32 of the first antenna 3 is disposed opposite to the micro slit tape 13. The first rf transceiver circuit 31 is configured to transmit and receive rf signals, which is also referred to as an rf chip. The first matching circuit 33 is configured to adjust the impedance matching of the first radiator 32, so that the first radiator 32 can better transmit and receive radio frequency signals.
The second antenna 4 includes a second rf transceiver circuit 41, a second radiator 42, and a second matching circuit 43 connected between the second rf transceiver circuit 41 and the second radiator 42. The second radiator 42 of the second antenna 4 is arranged opposite one of the slots 14.
The third antenna 5 includes a third rf transceiver circuit 51, a third radiator 52, and a third matching circuit 53 connected between the third rf transceiver circuit 51 and the third radiator 52. The third radiator 52 is arranged opposite to the other one of the slits 14.
The first rf transceiver circuit 31 may be configured to process radio frequency signals such as GPS signals, bluetooth signals, wiFi signals, or mobile communication signals (e.g., mobile communication signals in different communication frequency bands under a network system such as GSM, CDMA, LTE, LTE-a). The second rf transceiver circuit 41 may be configured to process radio frequency signals such as GPS signals, bluetooth signals, wiFi signals, or mobile communication signals (e.g., mobile communication signals in different communication frequency bands under a network system such as GSM, CDMA, LTE, LTE-a). The third rf transceiver circuit 51 may be configured to process radio frequency signals such as GPS signals, bluetooth signals, wiFi signals, or mobile communication signals (e.g., mobile communication signals in different communication frequency bands under a network system such as GSM, CDMA, LTE, LTE-a).
The first rf transceiver circuit 31 of the first antenna 3 and the second rf transceiver circuit 41 of the second antenna 4 are configured to process different rf signals, for example, rf signals with the same signal type and different signal frequency bands, or rf signals with different signal types. The radio frequency signal processed by the third radio frequency transceiver circuit 51 is different from the first radio frequency transceiver circuit 31, and the radio frequency signal processed by the third radio frequency transceiver circuit 51 may be the same as or different from the radio frequency signal processed by the second radio frequency transceiver circuit 41.
In other embodiments, as shown in fig. 5, the mobile terminal 100 includes an antenna device 200. The antenna device 200 includes a radio frequency transceiver circuit 7, a matching circuit 8, and the housing 1. The radio frequency transceiver circuit 7 is electrically connected to the conductive part 11 through the matching circuit 8. The conductive part 11 forms a radiator of the antenna device 200. The radio frequency transceiver circuit 7 and the matching circuit 8 are located inside the housing 1.
In the present embodiment, the antenna device 200 may include a plurality of the rf transceiver circuits 7 and a plurality of the matching circuits 8 corresponding to the plurality of the rf transceiver circuits 7. When a plurality of the matching circuits 8 are connected to the conductive portion 11, the conductive portion 11 is multiplexed into different radiators (which may be achieved by grounding at a desired position or by forming a loop through capacitive coupling).
It can be appreciated that by sharing the conductive portion 11 to form different radiators corresponding to different radio frequency transceiver circuits 7, the internal space of the mobile terminal 100 can be effectively saved, and the influence of the metal housing of the mobile terminal 100 on the radiation performance of the antenna can be reduced, so as to improve the signal transceiver performance of the antenna device 200.
Optionally, the width h of the micro-slit 131 is 0.05mm to 0.15mm, in this embodiment, the width h of the micro-slit 131 is 0.06mm, and is hardly visible to the naked eye, so that the integrity of the appearance of the housing 1 is improved while the antenna radio frequency signal of the mobile terminal 100 is ensured to pass through.
Referring to fig. 1 to 5, as an alternative embodiment, the width H of the slit 14 is greater than the width H of the micro slit 131. Since the width H of the slit 14 is large, the slit 14 may be formed by mechanical cutting. Since the width h of the micro-slit 131 is small, the micro-slit 131 may be formed by laser cutting. For example, the micro-slit tape 13 may be formed by laser cutting, and then the materials at both ends of the micro-slit tape 13 may be removed by mechanical cutting to form the two slits 14. At this time, in the mechanical cutting process, the material near the two ends of the micro-slit tape 13, which is deformed by the stress impact in the laser cutting process, can be removed, so that the machining accuracy of the insulating portion 12 is improved, and the yield of the product of the case 1 is high.
Optionally, the width H of a single slit 14 is greater than the sum of the widths H of all micro slits 131. At this time, the width H' of the whole micro slit tape 13 is similar to the width H of the slit 14, so that the integrity of the insulating part 12 is improved.
Optionally, the width H of the single slit 14 is equal to the width H' of the micro slit tape 13. At this time, the insulating part 12 has a uniform width in a direction perpendicular to the extending direction thereof, so that the integrity of the external appearance of the housing 1 can be improved, making the user's experience feel better.
Referring to fig. 1 to 5, as an alternative embodiment, the micro-slit tape 13 includes at least one separation strip 132 for separating the micro-slits 131, where the separation strip 132 is made of the same material as the conductive portion 11. At this time, the separation strip 132 and the conductive portion 11 have a relatively consistent appearance, which is beneficial to improving the integrity of the appearance of the housing 1.
In one embodiment, the micro-slits 131 are spaced apart from each other, for example, spaced apart from and parallel to each other, which is exemplified by the present application. In another embodiment, the plurality of micro-slots 131 may also be present in intersecting regions.
Optionally, the width h' of the separation strip 132 is greater than or equal to the width h of the micro slit 131. The ratio of the area of the slit 14 of the micro slit tape 13 is less than 50%, so that the integrity of the shell 1 with better appearance under the visual sense of naked eyes is further ensured.
Referring to fig. 1 to 7, as an alternative embodiment, the housing 1 includes two long sides 15 disposed opposite to each other and two short sides 16 connected between the two long sides 15 opposite to each other. The two slits 14 extend to the two long sides 15, respectively. In other words, the insulating portion 12 extends from one of the long sides 15 to the other long side 15. The housing 1 is substantially rectangular. The direction of extension of the micro-slit tape 13 coincides with the direction of extension of the short side 16 of the housing 1.
In one embodiment, as shown in fig. 6, the micro-slit tape 13 is spaced from the short side 16, and the camera module 6 of the mobile terminal 100 is located between the micro-slit tape 13 and the short side 16. In another embodiment, as shown in fig. 1 to 5, the micro-slit tape 13 is disposed near the short side 16, and the camera module 6 of the mobile terminal 100 is located at a side of the micro-slit tape 13 away from the short side 16. The micro-slit tape 13 is arranged close to the short side 16 such that the micro-slit tape 13 is visually very close to the edge of the housing 1 in appearance, so that the integrity of the appearance of the housing 1 is better.
When the plurality of micro slits 131 of the micro slit tape 13 are spaced apart from and parallel to each other, the extending direction of the plurality of micro slits 131 coincides with the extending direction of the short side 16 of the housing 1.
Optionally, each slit 14 includes an arc segment 141 and a straight segment 142, and the arc segment 141 is connected between the straight segment 142 and the micro slit strip 13. At this time, the straight line segment 142 may extend to the two long sides 15 of the housing 1, so that the straight line segment 142 is easier to process, and the processing difficulty of the slit 14 is reduced. The arc line section 141 can smoothly transition the straight line section 142 and the micro-gap strip 13, so as to reduce the processing difficulty of the insulating portion 12. The adjacent short sides 16 and long sides 15 of the housing 1 are transited by an arc 17, and the arc section 141 has the same or similar shape as the arc 17.
Optionally, the extending direction of the straight line segment 142 coincides with the extending direction of the short side 16 of the housing 1. The extending direction of the straight line segment 142 is identical to the extending direction of the micro slit tape 13.
In another embodiment, as shown in fig. 7, the insulating portion 12 may also extend from one of the long sides 15 to one of the short sides 16. At this time, the micro-slit tape 13 may have a substantially straight shape. One of the slits 14 may be perpendicular to the other slit 14.
In yet another embodiment, the insulating portion 12 may also extend from one of the short sides 16 to the other short side 16.

S02: a micro-slit tape 13 is formed on the case base material by laser cutting, wherein the micro-slit tape 13 has a plurality of micro-slits 131. It will be appreciated that the laser cut area is within the predetermined area of the insulating portion 12, but may extend beyond the area of the micro slit tape 13, for example, from the area of one micro slit 131 to the area of the other slit 14, which is advantageous for improving the cutting quality of the plurality of micro slits 131. An auxiliary cooling treatment may be performed during the laser cutting process to reduce the temperature during the laser cutting process, thereby forming the desired micro-slits 131. It can be appreciated that the auxiliary cooling treatment is a high-pressure nitrogen auxiliary cooling treatment.
S03: two slits 14 are formed on the base material of the housing by mechanical cutting, wherein the two slits 14 are connected to two ends of the micro-slit tape 13, and each micro-slit 131 is connected to the two slits 14. The mechanically cut area corresponds to the area of the two slits 14, and when the material in the area of the two slits 14 is removed, the material that is near the two ends of the micro-slit tape 13 and is deformed due to the stress impact in the laser cutting process can be removed, so that the machining precision of the insulating part 12 is improved, and the product yield of the housing 1 is higher.
