Description

A kind of communication device

Technical field

The utility model relates to a kind of communication device, the communication device of particularly a kind of replaceable external member unit (antenna casing).

Background technology

In the present radio communication product, mobile phone for example, its antenna structure mode roughly is divided into following two kinds: cylinder screws in fixed (Fig. 1), tenon coupling structure (Fig. 2).

As shown in Figure 1, the antenna structure that had of mobile phone P1 belongs to cylinder and screws in fixed.Mobile phone P1 includes a main frame M1 and a column type antenna M2, and wherein, column type antenna M2 is fixed on the main frame M1 in the screw-in mode.Yet owing to be subjected to the restriction of antenna processing mode, its aerial coil module (not indicating among the figure) adopts one-body molded mode mostly with antenna casing (not indicating among the figure).When desire was changed antenna casing, then aerial coil module and antenna casing all must be changed simultaneously, except the increase that causes cost, have caused the operational inconvenience of user simultaneously.

Moreover because the outer material of antenna adopts polyoxygenated dimethylbenzene (PPO) made mostly, the PPO material behavior limits its surface can not carry out application, the color that can adopt material itself to be had only, and the design for product has caused many restrictions virtually.

As shown in Figure 2, the antenna structure that had of mobile phone P2 belongs to the tenon coupling structure.Mobile phone P2 includes a main frame N1 and an antenna N2, and wherein, antenna N2 one side is formed with two trip K, and antenna N2 is connected on the main frame N1 by trip K.

Though, the mobile phone P2 of this tenon coupling antenna structure can suitably solve problems such as above-mentioned mobile phone P1 (screwing in the fixed antenna structure) material and appearance color, and also can provide the variation of different outward appearances, but because the assembling mode of antenna N2 must fasten via the outside of main frame N1, and when reaching mutually between trip K and the main frame N1 when engaging, this antenna N2 just can't change arbitrarily, promptly will change antenna N2, then must disassemble for the structure of main frame N1.

Summary of the invention

In view of this, the purpose of the utility model just is to provide the communication device of a kind of replaceable external member unit or antenna casing, so to satisfy appearance design novelty and convenient user's operation, it not only can be implemented in not tear open freely changes antenna casing under the machine state, more can not overcome because of the border at the antenna casing in the traditional design of present radio communication product is easily changeable simultaneously.

For reaching above-mentioned purpose, the utility model provides a kind of communication device, and this communication device comprises a body, a circuit unit, an antenna element and an external member unit, and wherein, the external member unit is the antenna casing of changeable type.Antenna element is arranged at body, includes at least one location division on antenna element.The external member unit includes a holding section, and the external member unit is arranged on the antenna element in separable mode by the holding section is matched with the location division of antenna element.

Thus, when if the user wants to change the external member unit of different patterns, the user can be easily via outside the communication device external member unit being pulled up, and change the own external member unit of liking pattern, needn't carry out loaded down with trivial details dismounting operation for other member of communication device fully, be a kind of structural design quite easily.

Embodiment

According to Fig. 3 to Fig. 5, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better architectural feature of the present utility model and function, characteristics.

Communication device E of the present utility model is mainly used in mobile phone (mobile phone) or other similar communication product, for example on the PDA.

Fig. 3 represents the stereogram according to the utility model communication device E, and this communication device E mainly comprises a body 1, a circuit unit 2 (shown in dotted line), an antenna element 3 and an external member unit 4, and wherein, external member unit 4 is the antenna casing of changeable type.

Body 1 has constituted the main machine structure of communication device E.Circuit unit 2 is arranged within the body 1, antenna element 3 is arranged on the body 1 to expose mode, wherein, antenna element 3 is electrically connected at circuit unit 2, with for sending, and receive and be sent to circuit unit 2 for the external data of communication device E by antenna element 3 by antenna element 3 from all relevant data of circuit unit 2.External member unit 4 is arranged on the antenna element 3 in separable mode, that is external member unit 4 can be according to user's demand and directly be arranged on the antenna element 3 via the outside of body 1.

Fig. 4 A-4C represents the partial perspective view according to the internal structure of the utility model communication device E among Fig. 3 respectively, wherein, Fig. 4 A represents antenna element 3, the structure chart when external member unit 4 is arranged at body 1, structure chart when Fig. 4 B represents that external member unit 4 is located away from the antenna element 3 of body 1 outside, Fig. 4 C represents antenna element 3, the structure chart when external member unit 4 is located away from body 1.
