[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0029] Conventional routers and other communication devices usually provide omnidirectional signal coverage, and omnidirectional signal transmission and reception are achieved by setting omnidirectional antennas, but there are often areas where the signal is weak. Although some products use directional antennas to enhance signals in specific directions, the radiation direction of directional antennas is fixed and cannot be adjusted in real time, affecting the user experience.
[0030] The utility model provides a directional antenna rotation mechanism and communication equipment. By rotating a rotating structure with a directional antenna, the radiation direction of the directional antenna can be adjusted, and the antenna signal in a specific direction can be strengthened. For example, the signal in the dead corner of the signal in various conventional environments such as toilets and kitchens can be strengthened to meet the special needs of users. At the same time, the rotating structure can also be manually controlled to rotate, realizing 360° signal enhancement without dead corners.
[0031] The directional antenna rotation mechanism provided in the embodiment of the utility model is now described.
[0032] Please also read Figure 1 and Figure 2 The directional antenna rotation mechanism includes a fixed structure 1, a driving component 12 and a rotating structure 2.
[0033] The fixed structure 1 is relatively fixed, and the fixed structure 1 can be the base part of the directional antenna rotation mechanism, used to support the directional antenna 22. The fixed structure 1 includes a fixing seat 11, and the fixing seat 11 can be an integral structure or a split structure. The fixing seat 11 can be a cubic, disc-shaped, cylindrical, etc. structure, and its specific shape is not limited here.
[0034] The driving assembly 12 is used to drive the rotating structure 2 to rotate, so as to adjust the orientation of the directional antenna 22 in the rotating structure 2. Specifically, the fixed structure 1 and the rotating structure 2 are connected through the driving assembly 12, and the driving assembly 12 can be a hinge assembly or a bearing assembly connecting the fixed structure 1 and the rotating structure 2, so that the rotating structure 2 can be rotated relative to the fixed structure 1 manually. The driving assembly 12 can also be an electrically driven component, which drives the rotating structure 2 to automatically rotate relative to the fixed structure 1 through an electrically driven motor or the like. The driving assembly 12 is arranged on the fixed structure 1, and the fixed structure 1 can provide a relatively stable installation position for the driving assembly 12.
[0035] The rotating structure 2 includes a rotating base 21 and a directional antenna 22. The directional antenna 22 is fixed on the rotating base 21, and the rotating base 21 rotates synchronously with the directional antenna 22. The directional antenna 22 refers to an antenna that transmits and receives electromagnetic waves particularly strongly in one or several specific directions, and transmits and receives electromagnetic waves relatively weakly in other directions. Since the directional antenna 22 is directional, when the directional antenna 22 faces a direction in which the signal is weak in space, the signal in that direction can be enhanced. When using the communication equipment, the position of the rotating structure 2 can be adjusted manually or automatically, so that the directional antenna 22 can face the direction where the signal is relatively weak to enhance the signal there.
[0036] The fixed seat 11 and the rotating seat 21 are respectively provided with a limiting structure, and the limiting structure is used to limit the rotation angle of the rotating seat 21, so that the rotation angle of the rotating seat 21 is within a preset range. The fixed seat 11 and the rotating seat 21 are respectively provided with a limiting structure, which can be understood as that one part of the limiting structure is arranged on the fixed seat 11, and the other part of the limiting structure is arranged on the rotating seat 21, and the limiting structures on the rotating seat 21 and the fixed seat 11 cooperate with each other to achieve the limitation of the rotating seat 21.
[0037] The directional antenna rotation mechanism in the above embodiment includes a fixed structure 1, a driving component 12 and a rotating structure 2. The driving component 12 causes the rotating structure 2 to rotate relative to the fixed structure 1. The rotating structure 2 includes a directional antenna 22. The driving component 12 drives the rotating structure 2, so that the directional antenna 22 can be rotated, thereby changing the radiation direction of the directional antenna 22, so that the directional antenna 22 radiates in the direction of weaker signals, so as to improve the overall performance of the communication device. At the same time, the position of the rotating structure 2 can be limited by the limiting structures set on the fixed seat 11 and the rotating seat 21.
[0038] In some embodiments of the present invention, please refer to Figure 4 and Figure 6The limiting structure includes two first limiting parts 112, a movable limiting part 113 and a second limiting part 212. The two first limiting parts 112 are arranged at intervals, and the two first limiting parts 112 are fixed to the fixed seat 11. The movable limiting part 113 is movably arranged on the fixed seat 11, that is, at least part of the movable limiting part 113 can produce relative movement relative to the fixed seat 11. At the same time, the movable limiting part 113 is arranged between the two first limiting parts 112, and when the movable limiting part 113 moves relative to the fixed seat 11, the movable limiting part 113 is always located between the two first limiting parts 112. The second limiting part 212 is fixed to the rotating seat 21, and the second limiting part 212 is used to abut and cooperate with the movable limiting part 113. It can be understood that when the rotating seat 21 is at two extreme positions, the movable limiting part 113 abuts against the two first limiting parts 112 respectively, and at the same time, the movable limiting part 113 also abuts against the second limiting part 212.
[0039] Specifically, when the rotating seat 21 rotates clockwise to a position close to the first limit position, the second limit portion 212 on the rotating seat 21 first contacts the movable limit portion 113, and the rotating seat 21 continues to rotate clockwise, and the second limit portion 212 pushes the movable limit portion 113 to move relative to the fixed seat 11 until the movable limit portion 113 abuts against one of the first limit portions 112. When the rotating seat 21 rotates counterclockwise to a position close to the second limit position, the second limit portion 212 on the rotating seat 21 first contacts the movable limit portion 113, and the rotating seat 21 continues to rotate counterclockwise, and the second limit portion 212 pushes the movable limit portion 113 to move relative to the fixed seat 11 until the movable limit portion 113 abuts against the other first limit portion 112. When the rotating seat 21 is at two limit positions respectively, the two sides of the movable limit portion 113 abut against the first limit portion 112 and the second limit portion 212 respectively.
[0040] See also Figure 5 After the rotating seat 21 rotates to contact the movable limit portion 113, the movable limit portion 113 can continue to be pushed to rotate. Therefore, the rotation angle range of the rotating seat 21 exceeds 360 degrees, that is, the movable space in which the rotating antenna can rotate is greater than 360°, avoiding dead angle positions.
[0041] In some embodiments, see Figure 5, the central angle of the sector formed by the two first limiting parts 112 and the rotation center of the rotating seat 21 is 5 to 10 degrees, such as 5 degrees, 7 degrees, 10 degrees, etc. When the rotating seat 21 rotates circumferentially, its rotation path has an overlapping area in the circumferential direction, and the overlapping area is the above-mentioned sector area. When the central angle corresponding to the sector area is too large, the rotation angle of the movable limiting part 113 is too large, resulting in the size of the movable limiting part 113 being too large and occupying too much space. When the central angle corresponding to the sector is too small, firstly, a dead angle may be formed between the two first limiting parts 112, and secondly, the distance between the two first limiting parts 112 is too small, which makes it difficult to lay out.
[0042] In some embodiments, see Figure 4 One end of the movable limiting part 113 is rotatably connected to the fixed seat 11, and the other end of the movable limiting part 113 is used to abut against the second limiting part 212. When the rotating seat 21 rotates until its second limiting part 212 abuts against the movable limiting part 113, the second limiting part 212 pushes the movable limiting part 113 to swing relative to the fixed seat 11. By setting the movable limiting part 113 to be rotatably connected to the fixed seat 11, the movement range of the movable limiting part 113 can be fan-shaped, and the positions of the two first limiting parts 112 are easier to design and layout.
[0043] In some embodiments, in the radial direction of the rotating seat 21, the second limiting portion 212 is farther away from the rotation center of the rotating seat 21 relative to the first limiting portion 112, so that the second limiting portion 212 is easier to move the movable limiting portion 113, and the force required to move the movable limiting portion 113 is smaller.
[0044] In some embodiments, the outer periphery of the movable stopper 113 is wrapped with a buffer layer, and when the first stopper 112 and the second stopper 212 contact the movable stopper 113, the buffer layer can reduce the sound generated during the stopper collision, and can also protect the movable stopper 113, the first stopper 112 and the second stopper 212. The buffer layer can be made of a deformable material such as silicone and rubber.
[0045] In some embodiments, the first limiting portion 112 is integrally formed with the fixing seat 11. Alternatively, the first limiting portion 112 is fixed to the fixing seat 11 by means of buckles, screws, etc.
[0046] In some embodiments, the second limiting portion 212 is integrally formed with the rotating seat 21. Alternatively, the second limiting portion 212 is fixed to the rotating seat 21 by means of buckles, screws, etc.
[0047] In some embodiments of the present invention, please refer to Figure 2 and Figure 3The driving component 12 is an electric driving component. The fixed end of the driving component 12 is fixed to the fixed seat 11, and the motion output end of the driving component 12 is fixedly connected to the rotating seat 21. In this way, through the operation of the driving component 12, the rotating seat 21 can be rotated relative to the fixed seat 11 to adjust the direction of the directional antenna 22. For example, the driving component 12 can be controlled by the mobile phone software to rotate the directional antenna 22 to a specific direction to enhance the signal in that direction; the directional antenna 22 can also be used to locate the position of the mobile phone to enhance the signal in the direction of the mobile phone. Specifically, after manually clicking on the location search on the mobile phone software, the directional antenna 22 first quickly rotates one circle for initial search, and the directional antenna 22 continuously sends and receives signals to the terminal to determine the position with the strongest signal. Then the directional antenna 22 rotates back to the vicinity of the strongest feedback signal, and the rotating seat 21 then rotates at a low speed to accurately locate the position with the strongest signal.
[0048] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 The driving assembly 12 includes a driver 121, a driving gear 122 and a driven gear 123. The motion output end of the driver 121 is connected to the driving gear 122, the driving gear 122 and the driven gear 123 are meshed with each other, and the driver 121, the driving gear 122 and the driven gear 123 are sequentially connected in transmission. Among them, the driven gear 123 is fixedly connected to the motion output end of the driving assembly 12, and the driven gear 123 is fixedly connected to the rotating seat 21.
[0049] By configuring the driving assembly 12 as a driver 121 and a gear assembly, the driving assembly 12 can move more smoothly, withstand a larger load, and have a higher movement accuracy.
[0050] In other embodiments, the driving assembly 12 may also be driven by a synchronous belt assembly or the like.
[0051] In some embodiments, the driver 121 is a motor.
[0052] In some embodiments, the driver 121 is fixed to the fixing base 11. Furthermore, the driver 121 can be fixed inside the fixing base 11, and the driver 121 is arranged in the internal space of the fixing base 11 to reduce the volume of the directional antenna rotation mechanism.
[0053] In some embodiments of the present invention, please refer to Figure 3 The fixed seat 11 has a first circumferential portion 111, and the rotating seat 21 has a second circumferential portion 211. The first circumferential portion 111 and the second circumferential portion 211 are coaxially arranged. The second circumferential portion 211 of the rotating seat 21 is fixedly connected to the driven gear 123 to achieve a fixed connection between the rotating seat 21 and the driven gear 123. A bearing 15 is arranged between the first circumferential portion 111 and the second circumferential portion 211.
[0054] By disposing the first circumferential portion 111 and the second circumferential portion 211 , the bearing 15 can be arranged between the fixed seat 11 and the rotating seat 21 , and the bearing 15 can make the rotation of the rotating seat 21 smoother and more stable.
[0055] In some embodiments, see Figure 3 There are two bearings 15, and a gasket structure 17 with adjustable thickness is arranged between the two bearings 15. The two bearings 15 are arranged in sequence along the axial direction of the rotating seat 21. When the thickness of the gasket structure 17 changes, the axial distance between the two bearings 15 also changes, so as to control the axial clearance of the two bearings 15 after installation and reduce the shaking of the rotating seat 21.
[0056] In some embodiments, the gasket structure 17 includes a plurality of gasket units stacked in layers, and the overall thickness of the gasket structure 17 can be changed by changing the number of gasket units. Specifically, when the thickness of the gasket structure 17 needs to be reduced, the number of gasket units can be reduced, and when the thickness of the gasket structure 17 needs to be increased, the number of gasket units can be increased.
[0057] In some embodiments, the gasket structure 17 is disposed between the inner rings of the two bearings 15, and the two sides of the gasket structure 17 are respectively in contact with the inner rings of the two bearings 15. Alternatively, the gasket structure 17 is disposed between the outer rings of the two bearings 15, and the two sides of the gasket structure 17 are respectively in contact with the outer rings of the two bearings 15.
[0058] In some embodiments of the present invention, please refer to Figure 3 , the first circumferential portion 111 is arranged on the outer periphery of the second circumferential portion 211, the first circumferential portion 111 is fixedly arranged, and the second circumferential portion 211 rotates relative to the fixed seat 11. A wiring channel 2110 is formed inside the second circumferential portion 211, and cables and the like can extend from the inside of the fixed seat 11 to the inside of the rotating seat 21 through the wiring channel 2110 to conduct the directional antenna 22. The axial ends of the inner ring of the bearing 15 are respectively abutted against the rotating seat 21 and the driven gear 123, the inner ring of the bearing 15 is fixedly connected to the second circumferential portion 211, one axial end of the outer ring of the bearing 15 is abutted against the fixed seat 11, and the other axial end is pressed and fixed by the clamping screw 16, and the outer ring of the bearing 15 is fixedly connected to the first circumferential portion 111. It can be understood that when the number of bearings 15 is one, the axial ends of the bearing 15 are the axial ends of the bearing 15; when the number of bearings 15 is multiple, the axial ends of the bearing 15 are the axial ends of the bearing group formed by multiple bearings 15.
[0059] By making the interior of the second circumferential portion 211 hollow, a wiring channel 2110 is formed inside the second circumferential portion 211. The wiring channel 2110 can not only allow cables to pass through and hide the cables inside the directional antenna rotation mechanism, but also allow the heat inside the directional antenna rotation mechanism to be quickly dissipated to the rotating seat 21 through the wiring channel 2110, thereby improving the heat dissipation efficiency.
[0060] In this embodiment, the inner ring of the bearing 15 rotates synchronously with the rotating seat 21, the outer ring of the bearing 15 is fixedly arranged, the two ends of the inner ring of the bearing 15 respectively abut against the rotating seat 21 and the driven gear 123, and the two ends of the outer periphery of the bearing 15 respectively abut against the fixed seat 11 and the clamping screw 16.
[0061] Optionally, see Figure 3 and Figure 6 One end of the first circumferential portion 111 has an L-shaped step, one end of the outer ring of the bearing 15 abuts against the L-shaped step, and the other end of the first circumferential portion 111 is threadedly connected with a clamping screw 16, the rod of the clamping screw 16 extends into the first circumferential portion 111, and the head of the clamping screw 16 abuts against the other end of the outer ring of the bearing 15.
[0062] In some embodiments, the second circumferential portion 211 is disposed on the outer periphery of the first circumferential portion 111, the first circumferential portion 111 is fixedly disposed, and the second circumferential portion 211 rotates relative to the fixed seat 11. The bearing 15 is disposed between the first circumferential portion 111 and the second circumferential portion 211, the outer ring of the bearing 15 is fixedly connected to the second circumferential portion 211, and rotates relative to the first circumferential portion 111, and the inner ring of the bearing 15 is fixedly connected to the first circumferential portion 111.
[0063] In some embodiments of the present invention, please refer to Figure 7 The fixing seat 11 has a protruding fixing column 114 inside, and the driver 121 has a fixing ear 1211. The fixing column 114 and the fixing ear 1211 are connected to each other, and a buffer pad 115 is provided between the fixing column 114 and the fixing ear 1211. The fixing column 114 is located inside the fixing seat 11, and the protrusion is provided on the inner wall of the fixing seat 11. The buffer pad 115 between the fixing ear 1211 of the driver 121 and the fixing column 114 can buffer the impact force between the two.
[0064] By setting the buffer pad 115, the noise of the driver 121 can be reduced from being transmitted to the fixing base 11 through the fixing ear 1211, thereby playing a role in sound insulation and noise reduction, and also reducing the impact of the vibration of the driver 121 on the fixing base 11.
[0065] The buffer pad 115 may be made of deformable materials such as silicone, rubber, etc.
[0066] In some embodiments, the fixing ears 1211 and the fixing posts 114 are provided with connection holes, and the fixing piece passes through the connection holes on the fixing ears 1211 and is connected to the connection holes of the fixing posts 114. Buffer pads 115 are provided between the fixing piece and the fixing ears 1211, and between the fixing ears 1211 and the fixing posts 114, so as to further enhance the ability of isolating noise and vibration between the driver 121 and the fixing base 11.
[0067] In some embodiments, the number of the fixing ears 1211 and the number of the fixing posts 114 are both two, and the two fixing ears 1211 and the two fixing posts 114 are matched one-to-one, so that the connection between the driver 121 and the fixing base 11 is more stable.
[0068] In some embodiments of the present invention, please refer to Figure 3 , an angular displacement sensor 18 is arranged on the fixed seat 11, and a radially magnetized magnet 19 is arranged at the center of the driving gear 122. The angular displacement sensor 18 is used to detect the angular displacement of the magnet 19. The radially magnetized magnet 19 means that half of the magnet 19 is an N pole and the other half is an S pole in the circumferential direction, and both the N pole and the S pole are semicircular. Therefore, when the magnet 19 rotates with the driving gear 122, a changing magnetic field will be generated. The angular displacement sensor 18 can instantly obtain the rotation angle of the driver 121 by measuring the change in the magnetic field, so that the real-time orientation of the directional antenna 22 can be measured in real time to ensure the positioning accuracy of the rotation.
[0069] In other embodiments, the magnet 19 may also be set at the center of the driven gear 123, and the angular displacement sensor 18 is set on the fixed seat 11 at a position corresponding to the center of the driven gear 123. The rotation angle of the driven gear 123 is calculated by the rotation angle of the magnet 19 relative to the angular displacement sensor 18, and then the corresponding position of the directional antenna 22 can be calculated.
[0070] In some embodiments of the present invention, please refer to Figure 2 The fixing structure 1 also includes a main board 13 and a sub-board 14. Both the main board 13 and the sub-board 14 are fixed to the fixing seat 11. The main board 13 and the sub-board 14 can be arranged perpendicular to each other, so as to be more conducive to the heat dissipation of the main board 13 and the sub-board 14.
[0071] In some embodiments, at least one side of the mainboard 13 is provided with a heat sink, which can effectively dissipate heat for the mainboard 13. And / or at least one side of the sub-board 14 is provided with a heat sink, which can effectively dissipate heat for the sub-board 14.
[0072] In some embodiments, heat dissipation holes are provided on at least one side of the fixed base 11 and at least one side of the rotating base 21, so that the heat generated by the main board 13 and the sub-board 14 can be quickly dissipated outward. The heat can also be transferred from the fixed base 11 to the rotating base 21 through the cable channel, etc., and then dissipated outward by the rotating base 21.
[0073] In some embodiments of the present invention, the fixing structure 1 further includes an omnidirectional antenna, which is fixed inside the fixing base 11. The number of the omnidirectional antennas can be four, which are respectively arranged at the four corners of the fixing base 11.
[0074] The utility model also provides a communication device, which includes the directional antenna rotation mechanism in any of the above embodiments. The communication device can be a router or the like.
[0075] The communication device provided by the utility model adopts the directional antenna rotation mechanism in any of the above embodiments, including a fixed structure 1, a driving component 12 and a rotating structure 2. The driving component 12 causes the rotating structure 2 to rotate relative to the fixed structure 1. The rotating structure 2 includes a directional antenna 22. The driving component 12 drives the rotating structure 2, which can rotate the directional antenna 22, thereby changing the radiation direction of the directional antenna 22, so that the directional antenna 22 radiates in the direction of weaker signals, thereby improving the overall performance of the communication device. At the same time, the position of the rotating structure 2 can be limited by the limiting structures set on the fixed seat 11 and the rotating seat 21.
[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
