Specific embodiment
Specific embodiment of the present utility model is described in more detail below in conjunction with the accompanying drawings.
The present embodiment is limited for the internal body space of intelligent watch, is not easy to reserve enough headroom for antenna assembly
Space, then causes antenna assembly that the problem of difficult antenna performance difference is laid in wrist-watch internal body, it is proposed that a kind of by antenna
The intelligent watch structure design mode of watchband is moved on to outside device, is embedded in watchband by by antenna assembly, effectively to break away from right
The limitation of wrist-watch cabinet size, then facilitates the design of wrist-watch body shape.
The intelligent watch of the present embodiment includes the chief components such as body 1, watchband 2,3, antenna modules 4, as shown in Figure 1, Figure 2
It is shown.Wherein, the body 1 of the present embodiment is to include that display screen 11, pcb board 12, watchcase 13, bottom 14, button 15 etc. complete intelligence
The general name of the part of energy wrist-watch basic function, body 1 is worn on user's by being connected to the watchband 2,3 of its left and right sides
In wrist.Antenna modules 4 coordinate the pcb board 12 in body 1 to set up wireless communication link with base station, complete the receipts to wireless signal
Hair, to realize the call function of intelligent watch.
Size in view of the body 1 of intelligent watch is limited, inner space is narrow and small, is not easy to antenna modules 4 wherein
Lay, thus antenna modules 4 are embedded in the design concept in watchband 2 or 3 for the present embodiment proposition.Specifically, can select
The wherein side watchband 2 or 3 of intelligent watch embeds described antenna modules 4.The present embodiment is embedded in right table with by antenna modules 4
Illustrated as a example by band 2.In order to realize assembling of the antenna modules 4 in watchband, the present embodiment opens up one on right watchband 2 first
Individual holding tank 21, as shown in Figure 2.Open up position of the holding tank 21 on right watchband 2 should be close proximity to body 1, convenient
While connecting pcb board 12 in body 1, when user wears intelligent watch, also will not cause day because of the bending of watchband 2,3
The bending of line module 4.When opening up the holding tank 21 on right watchband 2, preferably formed on the outer surface 22 of right watchband 2 and opened
Mouthful, inner surface 23 is remained intact, to avoid having influence on comfortableness when user wears.The advance embedded metal in right watchband 2
Shell fragment 24, one end for designing the metal clips 24 extends to body 1, for contacting connection with the pcb board 12 in body 1；
The other end extends to described holding tank 21, for being in contact with the antenna modules 4 in holding tank 21.The metal

121 right side, i.e., at the position of right watchband 2（When certainly, being embedded in left-handed watch with 3 for antenna modules 4, will should penetrate
Frequency plate 122 is laid in the left side of mainboard 121）, and signal feed and ground feed point are laid on the rf board 122, Huo Zhe
The antenna-matching circuit of the connection signal feed is further laid on rf board 122, to facilitate the resonant frequency of tuned antenna.
Antenna modules 4 are contacted into conducting by metal clips 24 with the signal feed and ground feed point that are laid on rf board 122, will be penetrated
The radiofrequency signal of the modulation generation of frequency plate 122 radiate, or the radiofrequency signal that antenna is received is sent to rf board 122 and enters
Go and demodulate, and then mainboard 121 is sent to by inter-board interface and processed.
In the present embodiment, the antenna modules 4 preferably form the matrix of antenna modules 4 using zirconia ceramics medium
41, with reference to shown in Fig. 3-Fig. 5.Because the dielectric constant of zirconia ceramics medium is high, 2-3 times of usually common LDS materials, because
This is conducive to shortening the length of antenna cabling so that the volume of antenna modules 4 is smaller, and signal is sensitiveer, and antenna performance is more preferable.
The arrangement of 3D antenna cablings is carried out on matrix 41, to form metal antenna body 42.In the present embodiment, it is preferred to use CIM skills
Art（CIM is the english abbreviation of ceramic injection moulding, i.e. ceramic powder injection molding technology）By antenna mould
The metal antenna body 42 of group 4 is formed in described matrix 41, to form the ceramic antenna of CIM techniques.Due to the pottery of CIM techniques
Porcelain antenna hardness is close to sapphire, therefore scratch-resistant, and reliability is high.
In the present embodiment, the matrix 41 of the antenna modules 4 is preferably designed to rectangular configuration, and height H is less than right table
With 2 thickness t, length L more preferably greater than 2/3rds of the width w of right watchband 2, in order to metal antenna body 42 thereon
Lay, with reference to shown in Fig. 2, Fig. 3.
The metal antenna body 42 can form PIFA antenna forms（As shown in Figure 3）, LOOP antenna forms（Such as Fig. 4
It is shown）Or IFA antenna forms（As shown in Figure 5）Deng polytype, specifically can be according to the actually used demand of intelligent watch
Preferentially determine.Pad is formed respectively at the signal feed 43 and ground feed point 44 of metal antenna body 42, is laid in matrix 41
On one of side 45, the side 45 is preferably the side that the width W and height H of matrix 41 are limited, i.e. parallel to right table
With 2 side, and the direction stretched out towards metal clips 24 in holding tank 21, in order to signal feed 43 and ground feed point 44 and gold
The category contact conducting of shell fragment 24.By the wire body part 46 of metal antenna body 42 from the signal feed 43 and ground feed point 44 to matrix
41 other surfaces extend, for example, extend in the upper surface 47 of matrix 41, or in the upper surface 47 and other sides of matrix 41
Face 48 extends, to meet the length requirement of antenna.
In order to be packaged to the antenna modules 4, and the overall aesthetics of intelligent watch outward appearance is improved, the present embodiment exists

Category shell fragment 34.One end of the metal clips 34 is extended to the direction of body 1, connection is contacted with the pcb board 12 in body 1,
Can specifically be connected with the ground wire on mainboard 121 in pcb board 12；The other end of metal clips 34 is extended to the groove, with
Conducting is contacted with the ground feed point in the radio frequency reference ground module 6 in groove.
In the present embodiment, it would however also be possible to employ zirconia ceramics medium forms the matrix 61 of radio frequency reference ground module 6,
And metal earth 62 is formed in described matrix 61 using ceramic powder injection molding technology, as shown in Figure 6.The present embodiment is preferred
The trace portions of metal earth 62 are formed in the upper surface 63 of matrix 61, using one of end of metal earth 62 as gold
The ground feed point of possession line 62, extends on one of side 64 of matrix 61, and forms pad 65, in order to metal clips
34 contact conductings.Connected with the ground wire on pcb board 12 by by metal earth 62, so as to extend the reference ground of antenna, improved
The low frequency performance of 2G antennas.
The radio frequency reference ground module 6 of the present embodiment is a selectable unit (SU) for intelligent watch, specifically should be according to reality
The size of the pcb board of border product decides whether apolegamy, if the length of pcb board is less than 40mm, it is proposed that configure this radio frequency reference ground
Module 6, to improve the low frequency performance of antenna.
Additionally, the overall aesthetics in order to not influence intelligent watch, the present embodiment decision design block plate 7 is installed in left-handed watch
In groove with 3, as shown in Figure 2.The opening of groove is blocked using block plate 7, and makes the outer surface of block plate 7 and a left side
The flush with outer surface of watchband 3, so as to keep watchband good appearance while, realize to radio frequency reference ground module 6 encapsulation and
Protection.
