DESCRIPTION OF EMBODIMENTS

[0037] The drawings of the present invention are for illustration purpose only and are not intended to limit the present invention. Some components in the drawings are omitted, enlarged or reduced for better illustrating the embodiments, and sizes of these components do not represent sizes of actual product. For those skilled in the art, it will be understood that some known structures in the drawings and descriptions thereof are omitted.

Embodiment 1

[0038] As shown in FIG. 1 or FIG. 3, a foldable panel antenna with two side plates according to the present embodiment comprises a main body 1 including a first vibrator, a first housing for coating the first vibrator, and a feeder terminal 100; two side plates 2 including a second vibrator and a second housing for coating the second vibrator; and a rotating mechanism which is designed to connect the main body 1 and the side plate 2 and to rotate the side plate 2 around the main body 1. The first vibrator is in electric connection with the second vibrator at the rotating mechanism. The main body 1 is connected to the side plate 2 through the rotating mechanism so that the side plate 2 can rotate around the main body 1.

[0039] In the present embodiment, the side plate 2 is configured with two side plates, which are symmetrically distributed on both sides of the main body 1, so that the television can receive signals well by rotating the two side plates 2, without the need to move the main body 1 of the panel antenna, to right face the source of the television signal to be received to make the receiving surface larger. In addition, the VHF signal can be better received as a large width exists between the two side plates 2 and the main body 1 of the panel antenna.

[0040] As shown in FIG. 2 and FIG. 4, in the present embodiment, the first housing has a double-layer panel structure, which is divided into a first front housing 110 and a first rear housing 120. The first vibrator is clamped in the interlayer formed by the first front housing 110 and the first rear housing 120. The second housing has a double-groove structure including a groove base 210 provided with a front groove and a rear groove, a front cover plate 221 and a rear cover plate 222. The second vibrator is divided into a second front vibrator and a second rear vibrator. The second front vibrator is clamped in the interlayer formed by the front groove and the front cover plate 221, and the second rear vibrator is clamped in the interlayer formed by the rear groove and the rear cover plate 222. Therefore, both sides of the side plate 2 can receive signals. When one surface of the active page of the panel antenna cannot receive signals due to a fault, or the signal reception is poor, such surface can be removed and the other surface without a fault can be installed and used by rotating 180, thus further improving the utilization of the panel antenna.

[0041] As shown in FIG. 1, the second housing in the present embodiment only coats the second vibrator outside in form of a grid structure. Since the active vibrator or passive vibrator for the panel antenna to receive signal are generally configured into a plurality of strip structures in parallel arrangement, which refers to the principle of Yagi panel antenna, the panel antenna in the present embodiment only coats the housing at the active vibrator or the passive vibrator to form a grid structure, which can save material and cost and reduce the weight of the panel antenna itself, making it lighter and more convenience to transport and carry.

[0042] In the present embodiment, the rotating mechanism is detachable. The main body 1 is in electric connection with the side plate 2. As shown in FIG. 2 and FIG. 4, the rotating mechanism includes a shaft 300 and a plurality of bearings arranged on the main body 1 and the side plate 2. The bearings are preferably sleeved on the shaft 300 to realize rotation. The rotating mechanism further includes a limit mechanism which can adjust an angle of the side plate 2 relative to the main body 1 within 0 to 180.

[0043] The side plate 2 and the main body 1 are detachably connected, and can be directly assembled when used, and the side plate 2 can be removed when not in use, making it more convenience to transport and carry. In addition, the active page of the side plate 2 of the antenna can be directly replaced when it needs to be repaired due to a fault without repair for the entire antenna. The rotating mechanism connecting the side plate 2 and the main body 1 is further provided with a limit mechanism for limiting the rotation angle of the side plate 2. The angle is set according to the preferred effect range of the received signal of the antenna, and is generally set between 0 and 180. Further, the configuration of the limit mechanism can also prevent the side plates 2 from rotating sharply, which may shorten service life of the antenna.

[0044] In the present embodiment, the bearings on the side plate 2 are symmetrically distributed, and the side plate 2 has a symmetric structure for being replaced by the other side and guaranteeing that the receiving signals are maintained to have the same stability as before when replaced by the other side.

[0045] In the present embodiment, the electrical connection mode between the main body 1 and the side plate 2 can be a flexible flat-cable connection. A gap exists between the bearings, so that the flexible flat-cable crosses the shaft 300 to realize electrical connection between the main body 1 and the side plate 2.

[0046] In the present embodiment, the bearing has a bearing seat, and the bearing seat is divided into a front bearing seat 310 and a rear bearing seat 320. The bearing seat is L-shaped, and the front bearing seat 310 and the rear bearing seat 320 are used for clamping the first front housing 110 and the first rear housing 120. Alternatively, the bearing seat is I-shaped, and the front bearing seat 310 and the rear bearing seat 320 are used for clamping the second front housing and the second rear housing.

Embodiment 2

[0047] As shown in FIG. 5, the embodiment provides a foldable panel antenna with four side plates 2. The panel antenna comprises a main body 1 including a first vibrator, a first housing coating the first vibrator, and a feeder terminal 100; the side plate 2 including a second vibrator and a second housing coating the second vibrator; and a rotating mechanism which is designed to connect the main body 1 and the side plate 2 and rotate the side plate 2 around the main body 1. The first vibrator is in electric connection with the second vibrator at the rotating mechanism, and the main body 1 is connected to the side plate 2 through the rotating mechanism so that the side plate 2 can rotate around the main body 1.

[0048] In the embodiment, the main body is in a square shape. The four side plates 2 are distributed in a center symmetric structure around the main body 1. Each side plate is connected to the main body through a rotating mechanism, so that the angles of the side plate 2 of the panel antenna can be adjusted in multiple directions, thereby obtaining more signals in different directions, so as to achieve optimal combination of the signal sources, and finally realizing the enhancement and optimization of the panel antenna signal.

[0049] The first housing and the second housing both have double-layer panel structures. The first housing is divided into a first front housing 110 and a first rear housing 120. The first vibrator is clamped in the interlayer formed by the first front housing 110 and the first rear housing 120. The second housing is divided into a second front housing 230 and a second rear housing 240. The second vibrator is clamped in the interlayer formed by the second front housing 230 and the second rear housing 240. The first housing and the second housing are both configured with double-layer panel structures, and the first vibrator and the second vibrator are respectively clamped in the interlayers of the first housing and the second housing, so that the whole panel antenna has small size, thin thickness, and light weight, is convenient to transport and install, and takes less transportation cost.

[0050] In the embodiment, the area of the main body 1 is greater than or equal to a sum of areas of the side plate 2. The four side plates 2 are in triangle with different shape. The area of each side plate 2 is less than or equal to a quarter of the area of the main body 1, and the side plate 2 cannot overlap with one another when folded. When needs to be stored, the side plate 2 is folded up. Each side plate 2 will not overlap and not exceed the size of the main body 1, making it more convenient to carry and more aesthetic quality.

[0051] In the embodiment, the rotating mechanism is detachable. The main body 1 is in electric connection with the side plate 2. As shown in FIG. 6, the rotating mechanism includes a shaft 300 and a plurality of bearings arranged on the main body 1 and the side plate 2. The bearings are sleeved on the shaft 300 to realize rotation. The rotating mechanism further includes a limit mechanism which can adjust an angle of the side plate 2 relative to the main body 1 within 0 to 180.

[0052] The side plate 2 and the main body 1 are detachably connected, and can be directly assembled when in use, and the side plate 2 can be removed when not in use, making it more convenient to transport and carry. In addition, active page of the side plate 2 of the antenna can be directly replaced when it needs to be repaired due to a fault without repair for the entire antenna. The rotating mechanism connecting the side plate 2 and the main body 1 is further provided with a limit mechanism for limiting the rotation angle of the side plate 2. The angle is set according to the preferred effect range of the received signal of the antenna, and is generally set between 0 and 180. Further, the configuration of the limit mechanism can also prevent the side plates 2 from rotating sharply, which may shorten service life of the antenna.

[0053] In the embodiment, the first housing and the second housing are molded using a PET film.

[0054] In the embodiment, the bearing has a bearing seat, and the bearing seat is divided into a front bearing seat 310 and a rear bearing seat 320. The bearing seat is L-shaped, and the front bearing seat 310 and the rear bearing seat 320 are used for clamping the first front housing 110 and the first rear housing 120. Alternatively, the bearing seat is I-shaped, and the front bearing seat 310 and the rear bearing seat 320 are used for clamping the second front housing 230 and the second rear housing 240.
