Description

Antenna device Technical Field

[0001] The embodiments of the present invention relate to the field of communication equipment, and more particularly to an antenna device. Background Art

[0002] Typically, antenna devices equipped with radiators are relatively large in size, thus occupying more space and supporting structures, causing inconvenience in transportation; and because the radiator is too long, its physical contact area is increased, making it easy to be damaged in harsh weather conditions, such as blizzards and lightning environments.

[0003] In view of the above problems, there is an urgent need for an antenna device that is flexible to use, easy to carry, and not easily damaged.

[0004] Summary of the Invention

[0005] The embodiments of the present invention provide an antenna device that is flexible to use, easy to carry, and not easily damaged.

[0006] An embodiment of the present invention provides an antenna device, which includes an antenna pole and a linear radiator; the linear radiator includes a radiating pole and a connecting assembly; the connecting assembly includes a rotating portion and a fixing member; a first end of the fixing member is fixedly connected to the antenna pole, and a second end of the fixing member is connected to the radiating pole via the rotating portion; the radiating pole rotates about the rotating portion as a rotation axis, so that the radiating pole is located in a first position or a second position; when the radiating pole is located in the first position, the radiating pole is in a folded state; when the radiating pole is located in the second position, the radiating pole is in an unfolded state.

[0007] In the present invention, the radiating rod in the antenna device can be flexibly rotated by the rotating portion. When the user is not using the radiating rod, the radiating rod can be rotated to a folded state by the rotating portion. When the user is using the radiating rod, the radiating rod can be rotated to an unfolded state by the rotating portion. Therefore, this design is not only convenient for the user to operate and carry, but also allows the radiating rod of the antenna to be flexibly adjusted in different environments, thereby preventing damage to the radiating rod and extending its service life.

[0008] In one possible design, the first end of the radiating rod includes a first hole; the second end of the fixing member includes a second hole; the rotating part is composed of the first hole, the second hole and a parent nail; the radiating rod is connected to the second end of the fixing member through the rotating part, including: the first hole of the radiating rod and the second hole of the fixing member are movably connected through the parent nail.

[0009] In the above, the parent nail can be inserted into the first hole and the second hole at the same time to connect the first hole and the second hole, which is equivalent to making the radiation rod and the fixing part movably connected, and the radiation rod actually rotates flexibly with the parent nail as the rotation axis to rotate to the expanded position or the folded position.

[0010] In one possible design, a threaded sleeve of a preset length is sleeved on the fixing member, and a first thread is provided on the inner side of the first end of the threaded sleeve; a second thread is provided on the outer side of the first end of the radiation rod, and the first thread and the second thread are matched with each other.

[0011] In the above, the first thread on the inner side of the threaded sleeve and the second thread on the outer side of the first end of the radiation rod can be matched and used to fix the radiation rod and the threaded sleeve.

[0012] In a possible design, before the radiating rod rotates with the rotating part as the rotation axis, the threaded sleeve is moved to the position of the fixing member; after the radiating rod is in the second position, the threaded sleeve is moved to the position of the rotating part, and the first thread of the threaded sleeve is clamped with the second thread on the outer side of the first end of the radiating rod.

[0013] In the above, the first thread on the inner side of the threaded sleeve and the second thread on the outer side of the first end of the radiating rod can be matched and used. Then, when the radiating rod is in the expanded state, the radiating rod, the rotating part and the fixing part are at the same level. The threaded sleeve on the fixing part can be moved to the rotating part, and the first thread and the second thread can be screwed together to fix the threaded sleeve to the radiating rod, so that the radiating rod is fixed to the fixing rod through the threaded sleeve to form a whole, and the radiating rod can no longer rotate at will.

[0014] In a possible design, when the radiation rod is located at the first position, the radiation rod and the antenna rod are parallel to each other; when the radiation rod is located at the second position, the radiation rod and the antenna rod are perpendicular to each other.

[0015] In the above description, when the radiating rod is not in use, the user can fold it so that it is parallel to the antenna pole (the angle can be 0° or 180°). This can reduce the space occupied by the radiating rod and make the antenna device easier to store and carry. When the radiating rod is in use, the user can unfold it so that the angle between the radiating rod and the antenna pole is 90°.

[0016] In one possible design, an antenna cap is mounted on one end of the antenna pole; the antenna cap is used for waterproofing and dustproofing; a connector is mounted on the other end of the antenna pole; the connector is used for communication of the antenna device.

[0017] In the above, the antenna cap can prevent water or dust from entering the antenna device, thereby affecting the performance of the antenna device; the connector on the antenna pole can be used to connect to a power source, and to send and / or receive electrical signals between the antenna device and other mobile terminal devices.

[0024] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0025] Figure 1 illustrates a schematic diagram of the structure of a current antenna device. As shown in Figure 1 , the antenna device includes an antenna mast 1 and four radiators 2, each of which is fixedly connected to both ends of the antenna mast 1. This antenna device lacks any rotatable components, making it difficult to store during transportation. When in use, it occupies more space and requires additional support structures for securement. In harsh weather conditions, such as snowstorms and lightning, the large physical contact area can easily damage the antenna.

[0026] In summary, the currently designed antenna devices are not only clumsy to use and inconvenient to carry, but also easily damaged.

[0027] In view of the above problems, the present invention discloses an antenna device that is flexible and portable, and is not easily damaged. Furthermore, the antenna device disclosed in the present invention can be applied to various terminal devices, or the antenna device itself can be used as a terminal device, without limitation to this aspect of the present invention.

[0028] 2 shows a structural diagram of an antenna device provided by an embodiment of the present invention, which includes linear radiators 100 , 200 , 300 , 400 , an antenna rod 500 , an antenna cap 600 , and a connector 700 .

[0029] In the embodiment of the present invention, each radiator may be a component that receives and releases electromagnetic waves and converts electromagnetic waves into electrical signals or vice versa.

[0030] Taking the linear radiator 100 as an example, the linear radiator 100 includes a radiating rod 101 and a connecting component 102; wherein, the connecting component 102 includes a rotating part 1021 and a fixing part 1022; the first end of the fixing part 1022 can be fixedly connected to the antenna rod 500, and the second end of the fixing part 1022 can be movably connected to the radiating rod 101 through the rotating part 1021, so that the radiating rod 101 rotates with the rotating part 1021 as the rotation axis, so that the radiating rod 101 is located in the first position or the second position.

[0031] When the radiation rod 101 is located at the first position, the radiation rod 101 is in a folded state.

[0032] In a possible design, when the radiation rod 101 is located at the first position, the radiation rod 101 and the antenna rod 500 are parallel to each other (for example, at an angle of 0° or 180°).

[0033] When the radiation rod 101 is located at the second position, the radiation rod 101 is in an unfolded state.

[0034] In a possible design, when the radiation rod 101 is located at the second position, the radiation rod 101 and the antenna rod 500 are perpendicular to each other (for example, at 90°).

[0035] The first end of the radiation rod 101 includes a first hole; the second end of the fixing member 1022 includes a second hole; the rotating part 1021 is composed of the first hole, the second hole and a parent nail; the radiation rod 101 is connected to the second end of the fixing member 1022 through the rotating part 1021, specifically: the first hole of the radiation rod 101 and the second hole of the fixing member 1022 are movably connected through the parent nail.

[0036] A sleeve 103 (i.e., a threaded sleeve) of a preset length is sleeved on the fixing member 1022, and a first thread is provided on the inner side of the first end of the sleeve 103; a second thread is provided on the outer side of the first end of the radiation rod 101, and the first thread and the second thread are matched with each other.

[0037] Before the radiation rod 101 rotates with the rotating portion 1021 as the rotation axis, the threaded sleeve needs to be moved to the position of the fixing member 1022 .

[0038] After the radiation rod 101 is located at the second position, the sleeve 103 needs to be moved to the position of the rotating portion 1021 , and the first thread of the sleeve 103 is locked with the second thread of the first end of the radiation rod 101 .

[0039] An antenna cap 600 is mounted on one end of the antenna pole 500; the antenna cap 600 is used to prevent water and dust. A connector 700 is mounted on the other end of the antenna pole 500; the connector 700 can be used to enable communication between the antenna device and other communication devices.

[0040] The specific use of the antenna device proposed in the embodiment of the present invention is described in detail below.

[0041] First, a detailed introduction is given on how to operate the antenna device so that the radiation rod can be folded.

[0042] Refer to Figure 3 (a), which shows the radiating rod in the unfolded state. First, move the sleeve 1 (i.e., the threaded sleeve) toward the antenna rod to the fixed position to expose the rotating part; then, refer to Figure 3 (b), with the sub-pin 1 of the rotating part as the rotation axis, rotate the radiating rod 90° to be parallel to the antenna rod, so that the radiating rod is in the folded state, that is, refer to the state of the radiating rod 1 shown in Figure 3 (c).

[0043] In the embodiment of the present invention, the number of radiators can be one or more (e.g., 4 or 6), and the present invention does not impose any specific limitation. In addition, the radiating rod can refer to a radiator that is straight and has a circular or elliptical cross-section, and the present invention does not impose any limitation on this either.

[0044] Exemplarily, when each radiating rod (i.e., radiating rod 1, radiating rod 2, radiating rod 3, radiating rod 4) is rotated with the rotating part as the rotation axis and is in a folded state, the front view of the antenna device can be seen as shown in Figure 4 (a), and the side view of the antenna device is shown in Figure 4 (b). It can be seen from the front view that each radiating rod is parallel to the antenna rod.

[0045] The following is a detailed introduction on how to operate the antenna device to unfold the radiation rod.

[0046] Referring to Figure 5(a), which shows the radiating rod in a folded state, the radiating rod 1 is rotated 90° with the pin 1 as the rotation axis, so that the radiating rod 1 is aligned with the fixing member and perpendicular to the antenna rod, as shown in Figure 5(b). Furthermore, the sleeve is moved away from the antenna rod until the sleeve threads contact the threads on the right side of the radiating rod. The sleeve threads are then rotated to engage with the threads on the right side of the radiating rod, securing the sleeve to the radiating rod, as shown in Figure 5(c). This secures the radiating rod to the fixing member through the sleeve, forming a single unit. At this point, the radiating rod can no longer rotate freely.

[0047] An embodiment of the present invention provides an antenna device in which a radiating rod can be flexibly rotated by a rotating portion. When not in use, the radiating rod can be rotated to a folded state by the rotating portion. When in use, the radiating rod can be rotated to an unfolded state by the rotating portion. This design of the antenna device is not only convenient for user operation and portability, but also allows the user to flexibly adjust the position of the antenna's radiating rod in different environments, thereby preventing damage to the radiating rod and extending its service life.

[0048] FIG6 is a schematic diagram of various components of an antenna device provided in an embodiment of the present invention. In this embodiment of the present invention, the antenna device may include a lower connector 601, an antenna cap 602, a connector 603, a sleeve 604, an upper fixing member 605, an upper radiating rod 606, a sub-pin 607, a lower fixing member 608, a lower radiating rod 609, and a support body 610. The functions of each component are shown in Table 1:

[0049] Table 1

[0050] In an embodiment of the present invention, the upper radiation rod 606 (or the lower radiation rod 609) is connected to the second end of the fixing member through a rotating part, which can specifically include: flexibly connecting the hole of the upper radiation rod 606 (or the lower radiation rod 609) with the corresponding hole of the upper fixing member 605 (or the lower fixing member 608) through the corresponding parent and child nails 611 (or parent and child nails 607).

[0051] In the above, the diameter of the hole can be larger than the parent and child nails 607, so that the parent and child nails 607 can connect the hole of the radiation rod with the hole of the fixing member.

[0052] In the embodiment of the present invention, an antenna cap 602 is bonded to one end of the support body 610 ; the other end of the support body 610 is connected to a connector 603 via a lower connector 601 ; the connector is used for communication of the antenna device.

[0053] In the above, the antenna cap is waterproof and dustproof; the connector 603 can be used to connect the power supply and electronic signals of the terminal device.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0055] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
