Embodiment
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with drawings and Examples, are further elaborated to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1-4(a), 4(b) shown in, described mobile terminal 1 comprises shell 10, be contained in terminal body 20 in described shell 10 and aerial coil 30.Described mobile terminal 1 can be any one in mobile phone, panel computer, notebook or POS, is not specifically limited at this.
Described shell 10 comprises the metal section 11 that offers through hole and covers described through hole and the non-metal portion 12 be connected with described metal section 11.Described non-metal portion 12 is connected with the surface of described metal section 11 towards described terminal body 20.Described non-metal portion 12 can adopt the plastics such as polyimides, polyethylene terephthalate, neopelex or polytetrafluoroethylene to be prepared from, and also can adopt other plastic material, even silica gel material.When described non-metal portion 12 is plastic material, to cover described through hole in its through hole that can be filled in described metal section 11 by injection molding manner.Described non-metal portion 12 is convexly equipped with lug boss 13 away from the surface of described terminal body 20.Described lug boss 13 forms annular groove 14 with the inward flange of described through hole.As Fig. 4 (a), 4(b) shown in, the inward flange of described through hole is more than or equal to the width a of described aerial coil 30 to the outer peripheral distance b of described lug boss 13.In other words, the width a of described aerial coil 30 is less than or equal to the width b of described ring groove 14, and distance b is the bigger the better, and a kind of situation of the limit is, there is not lug boss 13.Described lug boss 13 can, for the lug boss be made up of nonmetallic materials, also can be the lug boss be made up of metal material.When shell 10 adopts metal material to make, when lug boss 13 adopts nonmetallic materials to make, can ensure that the magnetic field energy of aerial coil 30 is not stopped completely, but now due to the material of lug boss 13 and the material of shell 10 inconsistent, the aesthetic property of whole shell 10 can be affected; And when lug boss 13 adopts metal material to make, high consistency can be kept with metal shell.In the present embodiment, described through hole and described lug boss 13 all rectangular, the described ring groove 14 that described lug boss 13 and the inward flange of described through hole are formed is three-back-shaped.
Described terminal body 20 comprises FPC wiring board 21.
Described aerial coil 30 is the air core coil being planar wound into scroll of multiturn.Described aerial coil 30 can be near-field communication aerial coil, also can be far-field communication aerial coil.Described aerial coil 30 is attached on described FPC wiring board 21, and its position is corresponding with the position of the non-metal portion 12 of described shell 10.In the present embodiment, when overlooking from the central axis direction of described aerial coil 30 winding, the location overlap of described aerial coil 30 and described ring groove 14, the Zone Full of described lug boss 13 is overlapped in the inside region of described aerial coil 30.
In the present embodiment, shell 10 major part of described mobile terminal 1 adopts metal material, and adopt nonmetallic materials at the correspondence position of the relatively described aerial coil 30 of described shell 10, because the position of the relatively described aerial coil 30 of described shell 10 is nonmetallic materials, magnetic flux so through closed-loop path is zero, thus described shell 10 can not produce contrary induced field to offset described aerial coil 30 magnetic field, the magnetic line of force in described aerial coil 30 magnetic field can pass from the non-metal portion 12 of described shell 10 simultaneously, magnetic field intensity can be ensured, therefore, the communication of the aerial coil 30 of described mobile terminal 1 can not be influenced.
In selectable another kind of execution mode, described aerial coil 30 is directly attached at the surface of described non-metal portion 12 towards described terminal body 20.
In selectable another kind of execution mode, as shown in Figure 5, the thickness of described non-metal portion 12 and the deep equality of described through hole, namely described non-metal portion 12 is in same plane away from the surface of described terminal body 11 and described metal section 11 away from the surface of described terminal body 11, make the outer surface of described shell 10 be a burnishing surface, described shell 10 seems more attractive in appearance.
Compared with correlation technique, the utility model mobile terminal 1 is not when changing terminal body 20 structure, by metal shell and aerial coil perfect adaptation, both met the hand-held texture of shell, attractive in appearance, durable effect, the effect that aerial coil outputs signal can have been ensured again.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
