Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a foldable antenna structure. Background Art

[0002] Workers working outdoors often need to use communication equipment. These devices typically have built-in communication modules and can function normally in a good network environment. However, in actual outdoor work, especially in wild valleys, network conditions are often poor. In such cases, it is necessary to connect the device to an external communication antenna to provide signal gain, allowing the device's transmitted signals to be better received by the communication base station, while also better receiving the signals sent by the communication base station. However, existing external antennas are mostly installed using bolts, which makes disassembly and installation more cumbersome and inconvenient.

[0003] In view of the above, it is necessary to provide a new foldable antenna structure to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to provide a foldable antenna structure, which can be directly plugged into a port of a communication device through its own connector, and the plugging is very convenient.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a foldable antenna structure, comprising: an upper body section, a lower body section, and a radio frequency signal line. A spring antenna and a circuit board are arranged inside the upper body section. The upper body section and the lower body section are hingedly connected. The radio frequency signal line is inserted and accommodated in the upper body section and the lower body section and is electrically connected to the spring antenna through the circuit board. The lower body section is provided with a connector.

[0006] Preferably, a ground pad and a feed pad are provided on the circuit board, the spring antenna is electrically connected to the ground pad and the feed pad on the circuit board, the RF signal line has a ground wire and a feeder wire inside, the ground wire is welded to the ground pad, and the feeder wire is welded to the feeder pad.

[0007] Preferably, the outer rings of the ground wire and the feeder wire are both wrapped with insulating rubber sleeves.

[0008] Preferably, the ground wire and the feeder are coaxially arranged, and the inner diameter of the ground wire is larger than the outer diameter of the feeder, and the feeder passes through the center of the ground wire.

[0009] Preferably, the connector is an SMA connector.

[0010] Preferably, the upper section of the body and the lower section of the body are hinged by a pin.

[0011] Compared with the existing technology, the beneficial effect is that a connector is provided at the lower part of the body, which can be directly plugged into the port of the communication equipment through the connector, which is very convenient.

[0017] In order to make the purpose, technical solution and beneficial technical effects of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0018] It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] It should also be noted that, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," "fixed," and "set" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will readily understand the specific meanings of these terms in this utility model based on specific circumstances.

[0020] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature identified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0021] See also Figures 1 to 2 The utility model provides a foldable antenna structure, including: an upper body section 1, a lower body section 2 and a radio frequency signal line 5. A spring antenna 6 and a circuit board 7 are arranged inside the upper body section 1. The upper body section 1 and the lower body section 2 are hinged. The radio frequency signal line 5 is inserted and accommodated in the upper body section 1 and the lower body section 2 and is electrically connected to the spring antenna 6 through the circuit board 7. The lower body section 2 is provided with a connector 3, which is connected to the communication port of the communication device through the connector 3.

[0022] In a preferred embodiment, the connector 3 is an SMA connector.
