The 50% of degree.
Above-mentioned metal shell construction, it is characterised in that the width of the slit is less than 3mm.
Above-mentioned metal shell construction, it is characterised in that also including a dope layer, the dope layer covers the metal shell
With slit.
For the above-mentioned purpose of this creation, feature and advantage can more be become apparent, hereafter with embodiment and it will coordinate appended
Schema, is described in detail below.It is noted that each component in institute's accompanying drawings is only signal, not according to the reality of each component
Border ratio is illustrated.
Brief description of the drawings

Fig. 2 show the top view of metal shell construction.
Fig. 3 show the setting schematic diagram of wireless communication module.
Fig. 4 show the current diagram on wireless communication module periphery.
Embodiment
Fig. 1 and Fig. 2 are referred to, Fig. 1 show the schematic diagram of metal shell construction, and Fig. 2 show metal shell construction
Top view.The metal shell construction 10 of this creation, is applicable to hand-held action device, such as intelligent mobile phone.And metal shell knot
There is slit 110 on structure 10, allow wireless communication module 200 not influenceed by metal shell, can normally receive and dispatch without news wire size, it is special
It is not RFID or NFC signals.
Metal shell construction 10 includes a metal shell 100 and a slit 110.In the present embodiment, metal shell 100 is
The unequal rectangle of one length and width, for example, backboard of intelligent mobile phone, in certain embodiments, four angles of metal shell 100
It can be arc-shaped, the shape or Aspect Ratio of metal shell 100 can be changed according to the mobile phone of different styles.
And slit 110 is arranged on the metal shell 100, and slit 110 is parallel with the narrow side of metal shell 100 and set
Put, and the horizontal length L of slit 110 is less than the length on the narrow side of metal shell.In preferred embodiment, the level of slit 110 is long
Degree L is greater than the 50% of the length on the narrow side of metal shell, and under the best circumstances, the horizontal length L of slit 110 should reach metal
More than the 80% of the length on the narrow side of housing.In addition, in the preferred embodiment, the width W of slit 110 is a fixed value, that is,
Say in the whole length of slit 110, width W is consistent, and width W is in below 3mm.Under optimum, slit
110 width should be maintained at below 0.5mm.
Referring to Fig. 2, from figure 2 it can be seen that one end of slit 110 is the edge for being connected to metal shell 100, and
The other end is then not connected to the edge of metal shell 100.In other words, the setting of slit 110 does not split metal shell 100,
Metal shell 100 is still an overall structure, and 100 can form slit 110 on metal shell by way of processing.
Slit 110 also includes multiple turning points 111, that is to say, that slit 110 is the shape with bending.In this embodiment
In, slit 110 has four turning point 111a~111d, and this four turning point 111a~111d are vertical turnover, and narrow
Seam 110 forms the slit 110 of S types by four turnovers.
In certain embodiments, material of becoming attached to can be filled in slit 110, the surface of its metal shell 100 is kept smooth,
Become attached to material for example, epoxy resin.In addition, the surface of metal shell 100 can also coat paint vehicle, slit 110 is hidden, makes metal
The outward appearance of housing 100 presents integral and complete.
Wireless communication module 200 is disposed on the lower section of metal shell 100, is covered under metal shell 100.Preferable
In embodiment, wireless communication module 200 is provided in the lower section of slit 110, enables wireless communication module 200 via slit 110
In expose, and can via slit 110 space propagation wireless signal.
Referring to Fig. 3, Fig. 3 show the setting schematic diagram of wireless communication module.Wireless communication module 200 also includes one
Antenna 210, antenna 210 is set around the periphery of wireless communication module 200, therefore antenna 210 can have an internal diameter I.And slit
110 because of the feature of its bending, can be repeatedly by the top of wireless communication module 200, in the preferred embodiment, by radio communication
The slit 110 of the top of module 200 all can position in the range of the internal diameter I of antenna 210, that is to say, that slit 110 can be kept and antenna
The configuration of the right and left wire vertically.
Referring to Fig. 4, Fig. 4 show the current diagram on the periphery of wireless communication module 200.When wireless communication module 200
When receiving and dispatching message, antenna 210 has electric current and flowed through.Now, the edge of slit 110 relative to wireless communication module 200 can sense
Go out the induced-current 300 of an opposite direction, induced-current can be moved along the outer rim of metal shell 100, therefore can be in metal shell
100 outer ring is produced and the sense of current identical induced-current 300 of antenna 210.And the meeting of induced-current 300 on the periphery of slit 110
Because the turnover of slit 110, induced-current 300 is set to repeal by implication.Therefore influence of the slit 110 to induced-current 300 is passed through, can
Antenna 210 is lived signal gain effect, effectively improve the communication distance of antenna 210.And the turnover of slit is more, close to day
Induced current path at line is elongated, helps to reduce shielding action of the metal backing to antenna signal, but too many slit will be made
Weaken into metal backing bulk strength, therefore slit turnover number is preferably 2-4.
This creation provides a kind of metal shell construction, can be applied to the action electronic devices such as mobile phone or tablet PC, and
There is metal shell construction slit to be able to receive and dispatch signal for the antenna of action electronic device, will not be done by the shielding of metal shell
Disturb.And the Position Design of slit can produce bigger field circuit, the communication context of antenna can be improved.In addition, metal shell knot
Only have the slit of one on structure, and by tortuous slit path, make that there is multiple tracks slit above antenna, therefore metal shell is not
It must split, can be the housing of integral type, it is possible to decrease part complexity and assembling flow path.
Above-described embodiment it is merely for convenience explanation and illustrate, though arbitrarily repaiied by person of ordinary skill in the field
Change, all without departing from such as the scope to be protected in claims.
