Description

Technical Field

[0001] This utility model relates to the field of communication transmission technology, specifically to an external antenna. Background Technology

[0002] External antennas are key components of wireless communication devices (such as routers, base stations, and vehicle-mounted communication terminals), and their radiation direction directly affects signal transmission quality. Traditional external antennas typically employ a fixed structure, meaning the angle between the antenna housing and the connector (such as an SMA connector or an N-type connector) is a fixed value (e.g., 90° vertically or 180° horizontally), requiring strict alignment with the target direction during installation. However, in practical applications, limitations in device installation location (e.g., inclined walls, narrow spaces), signal obstruction (e.g., building reflections, obstacle interference), or the need for multi-device collaboration (e.g., multi-antenna diversity reception) necessitate flexible adjustment of the antenna's radiation angle to optimize signal coverage. Therefore, developing an external antenna with adjustable angle, simple and reliable structure, and convenient operation has significant practical value. Utility Model Content

[0047] like Figure 1-8 As shown, this external antenna includes an antenna housing 1 and a connector 2;

[0048] The antenna housing 1 and the connecting base 2 are connected by a rotating structure 5. The rotating structure 5 is used to rotate the antenna housing 1 relative to the connecting base 2 to form different angles, mainly involving the adjustment of four commonly used angles: ±45 degrees and ±90 degrees.

[0049] The antenna housing 1 includes a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are arranged opposite to each other and sealed together. The first housing 101 and the second housing 102 together form a storage cavity.

[0050] The PCB antenna 3 is provided inside the receiving cavity. The PCB antenna 3 is provided with an antenna signal feed point. Neither the PCB antenna 3 nor the antenna signal feed point has any prior art, so they will not be described in detail here.

[0051] The connector 2 is provided with a coaxial line 4, and the end of the coaxial line 4 away from the connector 2 extends into the receiving cavity and is electrically connected to the antenna signal feed point.

[0052] like Figure 1-8As shown, in this embodiment, preferably, the rotating structure 5 includes a first fixing block 501 disposed on the upper end of the connecting seat 2;

[0053] The first fixing block 501 is provided with a first fixing plate 502 and a second fixing plate 503 on its front and rear sides respectively, and a first clamping groove 504 is formed between the two. The lower end surfaces of the first fixing plate 502 and the second fixing plate 503 are flush with the lower end surface of the first fixing block 501. The upper ends of the first fixing plate 502 and the second fixing plate 503 are rounded. The purpose of rounding the corners is to facilitate subsequent rotation without causing interference.

[0054] The first fixing block 501 has a first through hole at its center for the coaxial line 4 to pass through, and the first through hole is located between the first fixing plate 502 and the second fixing plate 503;

[0055] The lower end of the antenna housing 1 is provided with a second fixing block 506. The front and rear sides of the second fixing block 506 are respectively provided with a third fixing plate 507 and a fourth fixing plate 508, and a second clamping groove 509 is formed between them. The depth of the second clamping groove 509 is greater than the height of the first fixing plate 502 or the second fixing plate 503. The lower ends of the third fixing plate 507 and the fourth fixing plate 508 are rounded. The purpose of rounding the corners is to facilitate subsequent rotation without causing interference.

[0056] The second fixing block 506 has a second through hole 510 at its center for the coaxial line 4 to pass through. The second through hole 510 is located between the third fixing plate 507 and the fourth fixing plate 508. The end of the coaxial line 4 away from the connecting seat 2 passes through the first through hole, the first groove 8, the second groove 9, and the second through hole 510 in sequence and extends into the receiving cavity to be electrically connected to the antenna signal feed point.

[0057] The third fixing plate 507 is located outside the first fixing plate 502 and the two are in sliding contact. The third fixing plate 507 is rotatably connected to the first fixing plate 502 via a rotating shaft 511, and the relative rotation of the third fixing plate 507 to the first fixing plate 502 is achieved via the rotating shaft 511.

[0058] The fourth fixing plate 508 is located outside the second fixing plate 503 and the two are in sliding contact. The fourth fixing plate 508 is rotatably connected to the second fixing plate 503 through a rotating shaft 511, and the relative rotation of the fourth fixing plate 508 on the second fixing plate 503 is realized through the rotating shaft 511.

[0059] Positioning structures are provided between the third fixing plate 507 and the first fixing plate 502, and between the fourth fixing plate 508 and the second fixing plate 503. These are two identical positioning structures. The positioning structures are used to limit the rotation of the third fixing plate 507 and the fourth fixing plate 508 to a specific angle, so that they will not rotate arbitrarily after the angle is adjusted, thus ensuring the stability between the antenna housing 1 and the connecting seat 2.

[0060] like Figure 4-8 As shown, in this embodiment, preferably, the positioning structure includes a first protrusion 6 and a second protrusion 7 disposed on the inner surface of the third fixing plate 507 and the fourth fixing plate 508, that is, the inner surface of the third fixing plate 507 is provided with the first protrusion 6 and the second protrusion 7, and the inner surface of the fourth fixing plate 507 is also provided with the first protrusion 6 and the second protrusion 7.

[0061] The first protrusion 6 is vertically arranged and located in the middle of the left-right direction, that is, the first protrusion 6 is located in the middle of the left-right direction of the third fixing plate 507 or the fourth fixing plate 508. The first protrusion 6 and the second protrusion 7 intersect and are perpendicular. The intersection of the first protrusion 6 and the second protrusion 7 is penetrated by the corresponding rotating shaft 511. The width and thickness of the first protrusion 6 and the second protrusion 7 are the same. The length of the first protrusion 6 is equal to the height of the third fixing plate 507 or the fourth fixing plate 508. The length of the second protrusion 7 is equal to the width of the third fixing plate 507 or the fourth fixing plate 508.

[0062] The outer surfaces of the first fixing plate 502 and the second fixing plate 503 are provided with a first groove 8, a second groove 9, a third groove 10 and a fourth groove 11, which intersect each other. The intersection of the first groove 8, the second groove 9, the third groove 10 and the fourth groove 11 is penetrated by the corresponding rotating shaft 511.

[0063] The first groove 8 is vertically arranged and located in the middle of the left-right direction. The second groove 9 is perpendicular to the first groove 8, that is, the second groove 9 is horizontally arranged and located in the upper middle part of the first fixing plate 502 or the second fixing plate 503.

[0064] The third groove 10 is inclined and forms an angle of 45 degrees with the first groove 8. The fourth groove 11 is inclined and is symmetrical to the third groove 10 about the first groove 8, that is, the fourth groove 11 and the third groove 10 are arranged in an X shape. In the initial state, the first protrusion 6 and the second protrusion 7 are located in the first groove 8 and the second groove 9 respectively, and the antenna housing 1 and the connecting seat 2 are collinear, that is, the antenna housing 1 is in a vertical state. When adjusting the angle of the antenna housing 1, the first protrusion 6 and the second protrusion 7 are rotated and squeezed out from the first groove 8 and the second groove 9 respectively, clockwise. When rotated 45 degrees, the first protrusion 6 is exactly located in the fourth groove 11, and the second protrusion 7 is exactly located in the third groove 10. When rotated 90 degrees clockwise, the first protrusion 6 is exactly located in the second groove 9, and the second protrusion 7 is exactly located in the first groove 8. When rotated 45 degrees counterclockwise, the first protrusion 6 is exactly located in the third groove 10, and the second protrusion 7 is exactly located in the fourth groove 11. When rotated 90 degrees counterclockwise, the first protrusion 6 is exactly located in the second groove 9, and the second protrusion 7 is exactly located in the first groove 8. By using the two protrusions in conjunction with the two grooves, the adjustment and limiting of a specific angle can be achieved.

[0065] In the above embodiments, preferably, the first protrusion 6 and the second protrusion 7 are made of elastic material, preferably a mixture of PC and ASA. The use of elastic material allows the first protrusion 6 and the second protrusion 7 to be squeezed and deformed to rotate out of the corresponding grooves when rotated. After rotating to a specific angle, the presence of the grooves will cause the squeezed and deformed first protrusion 6 and the second protrusion 7 to recover their deformation and be stuck in the two grooves to achieve positioning, thereby preventing the antenna housing 1 from rotating arbitrarily. At the same time, it can be clearly known that the angle of rotation is 45 degrees. When a 90-degree rotation is required, the operation can be repeated.

[0066] like Figure 8 As shown, in this embodiment, in order to ensure that the first protrusion 6 and the second protrusion 7 can smoothly slide out of the corresponding groove when rotating, the two sides of the surface of the first protrusion 6 away from the corresponding fixing plate are beveled, and the two sides of the surface of the second protrusion 7 away from the corresponding fixing plate are beveled. The beveled edges guide the transition, so that the first protrusion 6 and the second protrusion 7 can smoothly rotate and slide out of the corresponding groove when rotating.

[0067] like Figure 5 , Figure 6 As shown, in this embodiment, in order to further ensure that the first protrusion 6 and the second protrusion 7 can slide smoothly out of the corresponding groove when rotating, the upper ends of the outer surfaces of the first fixing plate 502 and the second fixing plate 503 are provided with sloping grooves 12, and the depth decreases from top to bottom.

[0068] The width of the sloping groove 12 is greater than the width of the first groove 8 and the two are interconnected. Since the lower end of the sloping groove 12 is shallower, the protrusion located there is easier to slide out from the lower end of the sloping groove 12, thereby causing other parts of the protrusion to better detach from the first groove 8. In other words, guided by the sloping groove 12, the part of the first protrusion 6 or the second protrusion 7 located in the upper half of the first groove 8 can be smoothly squeezed out of the upper half of the first groove 8, thereby allowing the entire protrusion to be smoothly squeezed and rotated to detach from the first groove 8.

[0069] like Figure 2 As shown, in this embodiment, in order to facilitate the installation of the positioning PCB antenna 3, the PCB antenna 3 is provided with a plurality of positioning through holes 13;

[0070] The inner surface of the first housing 101 is provided with a plurality of positioning posts 14. The number of positioning posts 14 is the same as the number of positioning through holes 13 and they correspond one-to-one. The positioning posts 14 are respectively located in the corresponding positioning through holes 13. Through the cooperation of the positioning posts 14 and the positioning through holes 13, it is convenient to install and position the PCB antenna 3, and at the same time, it also plays a role in supporting the PCB antenna 3 and preventing mistake.

[0071] In this embodiment, preferably, the connector 2 is an SMA connector.

[0072] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
