Table, smartwatch show the time, other than the date in addition to having the function of, also have human heart rate's detection, satellite navigation and positioning, wirelessly
The functions such as payment, voice communication and data transmission.Meanwhile NB-IoT technology belongs to a scope of wireless mobile communications, because
This, antenna needed for the smartwatch for applying NB-IoT technology similarly needs to equip wireless communication, smartwatch is a kind of
Wearable device has the product designs requirements such as carrying portable, size be small and exquisite, still, when designing NB-IoT antenna on smartwatch,
The problems such as antenna reserved space is small, antenna surrounding enviroment are complicated, interference is more are unable to satisfy, NB-IoT antenna is caused to be difficult in intelligence
It can be promoted and applied on wrist-watch.
Utility model content
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, providing one kind can be in small sky
Interior setting NB-IoT antenna, while overcoming the smartwatch NB-IoT antenna structure interfered in table.
In order to solve the above technical problems, the utility model adopts the following technical solution.
A kind of NB-IoT antenna structure for smartwatch, the smartwatch include the watchcase of isolation material, set
In wiring board and antenna body in the watchcase, the antenna body fits in the inner wall of the watchcase, and the antenna
Ontology is formed with current feed department and grounding parts on the antenna body, the wiring board is equipped with along the circumferentially extending of the watchcase
Power feed contact and grounding contact, the power feed contact are abutted against with the current feed department, the grounding contact and the grounding parts phase
It abuts.
Preferably, the watchcase is the watchcase of plastic material.
Preferably, the power feed contact and grounding contact are pogo pin probe.

Preferably, the antenna body is close to the upper edge of the watchcase, and between the antenna body and the becket
Form pre-determined distance.
Preferably, the antenna body is in " ㄈ " shape close to one end of the power feed contact and grounding contact.
Preferably, the one end of the antenna body far from the power feed contact and grounding contact is in Z-shaped.
In NB-IoT antenna structure disclosed by the utility model for smartwatch, the antenna body is closely attached on institute
The inner wall of watchcase is stated, and makes the antenna body along the circumferentially extending of the watchcase, so that enough antenna sizes are formed, then
The electric connection of feed and earthing position is realized using power feed contact and grounding contact.Compared to existing technologies, this is practical new
Type dexterously avoids the interference source that antenna performance can be influenced on wiring board, so that work frequency of the antenna in NB-IoT technical requirements
Preferable performance is obtained in section, smartwatch is caused to meet the design requirements such as people is connected with object, object is connected with object, meanwhile, the day
Line occupies little space, save the cost, and mentality of designing is simple, practical, is suitble to promote in smartwatch technical field and answer
With.
Detailed description of the invention
Fig. 1 is the internal structure chart of smartwatch；
Fig. 2 is the structure chart one of watchcase and antenna body；
Fig. 3 is the structure chart two of watchcase and antenna body；
Fig. 4 is the S11 curve graph of the utility model NB-IoT antenna structure.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and examples.
The utility model discloses a kind of NB-IoT antenna structures for smartwatch, in conjunction with shown in Fig. 1 to Fig. 3, institute
State the watchcase 1 that smartwatch includes isolation material, wiring board 2 and antenna body 3 in the watchcase 1, the day
Line ontology 3 fits in the inner wall of the watchcase 1, and the antenna body 3 is along the circumferentially extending of the watchcase 1, the antenna sheet
Current feed department and grounding parts are formed on body 3, the wiring board 2 is equipped with power feed contact 4 and grounding contact 5, the power feed contact 4
It is abutted against with the current feed department, the grounding contact 5 is abutted against with the grounding parts.
In above-mentioned NB-IoT antenna structure, the antenna body 3 is closely attached on to the inner wall of the watchcase 1, and is made described
Antenna body 3 recycles power feed contact 4 and ground connection touching to have enough antenna sizes along the circumferentially extending of the watchcase 1
First 5 realize the electric connection of feed and earthing position.Compared to existing technologies, the utility model dexterously avoids wiring board
