Description

Technical Field

[0001] The present invention relates to the field of communication devices, and particularly to a fixing device for WIFI antenna adjustment. Background Art

[0002] Wireless network in the scope of wireless local area network refers to "Wireless Fidelity", which is essentially a commercial certification and also a wireless networking technology. Previously, computers were connected through network cables, while Wi-Fi connects to the network through radio waves. Commonly, there is a wireless router. Then, within the effective range covered by the radio waves of this wireless router, the Wi-Fi connection method can be used for networking. If the wireless router is connected to an ADSL line or other Internet access lines, it is also called a hotspot. The WIFI antenna is a common structure on the router, mainly to enhance the wireless network signal, and it is divided into two types: built-in and external. In the existing WIFI router and antenna configuration technology, a common drawback is that the physical direction of the antenna body is often fixed and cannot be automatically adjusted according to the signal strength changes in the surrounding environment. This fixed design is particularly limited in complex environments because signal propagation is affected by various factors such as building blockages and electromagnetic interference, which may lead to a decline in signal quality in a specific direction.

[0003] Specifically, the antennas of traditional WIFI routers are usually installed on the router through fixing methods such as screws or buckles. Once installed, their orientation cannot be changed. When the router is placed in an area with a complex signal environment, such as a room corner, inside a multi-story building, or an area with a large number of metal obstacles, the fixed antenna direction may not be able to capture the strongest signal source, resulting in unstable network signals, reduced speed, or even signal loss.

[0004] In addition, even if users are aware of the signal problem and try to manually adjust the antenna direction, they often have difficulty finding the optimal position due to the lack of precise measurement tools and professional knowledge, and this adjustment is usually static and cannot be adjusted in real time according to the dynamic changes of the signal environment. For this reason, we propose a fixing device for WIFI antenna adjustment. Summary of the Invention

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides a fixing device for adjusting a WIFI antenna, which has the following beneficial effects:

[0023] 1. The fixing device based on WIFI antenna adjustment monitors the wireless signal strength of the surrounding environment through the internal signal strength sensor during the use of the WIFI router. When the signal strength of the antenna body becomes weak, the internal controller of the WIFI router adopts a microprocessor or a single-chip microcomputer as a controller, which is responsible for receiving the data of the sensor and calculating the best antenna direction based on a preset algorithm. At this time, the power plug and the communication plug connected to the power interface and the communication interface in the connector and the interface socket transmit electrical signals to the electrical components in the adjustment structure. The adjustment structure can be used to adjust the angle of the antenna body in a two-dimensional space parallel to the end face of the connector, and at the same time drive the antenna body to adjust the angle in a two-dimensional space perpendicular to the end face of the connector, so that the antenna body can be automatically adjusted at any angle in three-dimensional space, so that the physical angle adjustment of the antenna body can be completed to adjust the direction of the beam by changing the phase or amplitude of the internal components. By optimizing the direction of the antenna body, the signal propagation path can be made smoother, and the attenuation and interference of the signal during the propagation process can be reduced, thereby improving the network speed.

[0024] 2. During the process of adjusting the direction and angle of the antenna body, for the fixing device for WIFI antenna adjustment, by making the sum of half the length of the horizontal shaft member and the length of the connecting rod greater than the straight-line length from the center point of the horizontal shaft member to the side corner of the connector, it is possible to ensure that during the process of the horizontal shaft member and the connecting rod driving the antenna body to flip and adjust, the circumferential movement trajectory range of the antenna body is larger than the end face range of the connector. This can avoid the situation where the antenna body collides with the outer surface of the connector, thereby improving the practicality of the fixing device for WIFI antenna adjustment and the rationality of the component operation process.

[0025] 3. For the fixing device for WIFI antenna adjustment, on both inner walls of the corresponding annular groove of the connector, densely arranged ball grooves are provided, and in each group of ball grooves, a ball body protruding from the inner wall of the side of the annular groove is rotationally clamped. The outer surface of the connecting rod is in sliding contact with the two ball bodies in the annular groove. During the process of the connecting rod driving the antenna body to flip along the annular groove, the smoothness of the connecting rod flipping can be improved, thereby further enhancing the practicality of the fixing device for WIFI antenna adjustment and the operation process of the components.

[0026] 4. For the fixing device for WIFI antenna adjustment, by arranging multiple groups of interface sockets on the top of the WIFI router, when the antenna body is in the vertical state, when driving the micro servo motor two to drive the flipping rod and the force arm rod to drive the vertical cylinder, the horizontal shaft member and the connecting rod can drive the antenna body to flip and fold towards the top of the WIFI router, which is conducive to the overall storage and placement of the WIFI router and the antenna body.

[0055] A direction adjustment structure is set between the antenna body 2 and the connector 4, and this direction adjustment structure is used to cooperate with the signal strength sensor and the controller to adjust the physical direction of the antenna body 2.

[0056] A power interface and a communication interface are provided in the interface socket 3. The front end of the connector 4 is fixedly provided with a power plug 5 and a communication plug 6 for plugging into the interface socket 3, and the electrical components in the antenna body 2 and the direction adjustment structure are electrically connected to the power plug 5 and the communication plug 6 to ensure that the entire system has a stable power supply to realize the communication and electrical data exchange between the antenna body 2, the WIFI router 1 and the direction adjustment structure.

[0057] The steering structure includes a micro servo motor 11, a U-shaped part 12, a horizontal shaft part 13, a vertical cylinder 14 and a connecting rod 15. The inside of the connector 4 is hollow. On one side of the connector 4 near the power plug 5 and the communication plug 6, a vertical substrate 10 is fixedly installed. At the center of the outer wall of the vertical substrate 10 near the front end of the connector 4, a micro servo motor 11 is fixedly installed. The output shaft of the micro servo motor 11 penetrates the side wall of the vertical substrate 10 and is fixedly connected to a horizontally placed U-shaped part 12. One end of the U-shaped part 12 facing away from the vertical substrate 10 is open, and a horizontal shaft part 13 is rotatably installed corresponding to the open end. A vertical cylinder 14 is fixedly sleeved in the middle of the horizontal shaft part 13. One end of the horizontal shaft part 13 penetrates the outer wall of one side of the U-shaped part 12 and is fixedly connected to a connecting rod 15. One end of the connecting rod 15 extends to the outside of the connector 4 and is fixedly connected to the antenna body 2 near the bottom end. The antenna body 2 is vertical and perpendicular to the connecting rod 15.

[0058] The central points of the connector 4, the micro servo motor 11, the U-shaped part 12, the horizontal shaft part 13 and the vertical cylinder 14 are on the same horizontal line.

[0059] On both sides and above the connector 4 corresponding to the vertical cylinder 14, an annular groove 7 with both sides and the top end communicating is provided, and the end of the connecting rod 15 passes through the annular groove 7 and extends to the outside of the connector 4.

[0060] The sum of half the length of the horizontal shaft part 13 and the length of the connecting rod 15 is greater than the straight-line length from the center point of the horizontal shaft part 13 to the side corner of the connector 4. This enables the circumferential movement trajectory range of the antenna body 2 to be greater than the end face range of the connector 4 during the process of the horizontal shaft part 13 and the connecting rod 15 driving the antenna body 2 to flip and adjust, thus avoiding the situation of the antenna body 2 colliding with the outer surface of the connector 4, and improving the practicability of the fixed device for WIFI antenna adjustment and the rationality of the component operation process.

[0061] On the inner walls of both sides of the connector 4 corresponding to the annular groove 7, densely arranged ball card slots 8 are provided, and in each group of ball card slots 8, a ball body 9 protruding from the inner wall of the side of the annular groove 7 is rotatably clamped. The outer surface of the connecting rod 15 is in sliding contact with the ball bodies 9 on both sides in the annular groove 7. This can improve the smoothness of the rotation of the connecting rod 15 during the process of the connecting rod 15 driving the antenna body 2 to flip along the annular groove 7, and further improve the practicability of the fixed device for WIFI antenna adjustment and the flowability of the component operation.

[0062] The direction adjustment structure also includes a flip rod 16, a force arm rod 17 and a micro servo motor 19. The micro servo motor 19 is fixedly installed on the side outer wall of the connector 4 near the tail end. The output shaft of the micro servo motor 19 extends to the interior of the connector 4 and is fixedly installed with a flip rod 16, and an integrated L-shaped horizontal top rod 18 is fixed to the top of the flip rod 16. The end of the L-shaped horizontal top rod 18 is bent and extends to just above the center point of the top of the vertical cylinder 14. The force arm rod 17 is rotatably installed at the midpoint of the side wall of the vertical cylinder 14 away from the micro servo motor 11. The force arm rod 17 is an inverted L-shape, and the horizontal top of the force arm rod 17 fits the bottom of the L-shaped horizontal top rod 18, and the top end of the force arm rod 17 is rotatably installed with the end of the L-shaped horizontal top rod 18.

[0063] The connection point between the micro servo motor 2 19 and the bottom end of the flip rod 16 and the center point of the horizontal axis 13 are located in the same horizontal plane, and the spacing distance between the outer wall of the U-shaped part 12 and the side inner wall of the connector 4 is greater than the spacing distance between the inner wall of the flip rod 16 and the side inner wall of the connector 4, thereby preventing the two sides of the U-shaped part 12 from affecting the flipping motion trajectory of the flip rod 16, and allowing the flip rod 16 to flip to a horizontal state.

[0064] Working principle: During the use of the WIFI router 1, the wireless signal strength of the surrounding environment is monitored by the internal signal strength sensor. When the signal strength of the antenna body 2 weakens, and the internal controller of the WIFI router 1 uses a microprocessor or a single-chip microcomputer as the controller, which is responsible for receiving the data of the sensor and calculating the optimal antenna direction based on a preset algorithm. At this time, the power plug 5 and the communication plug 6 inserted into the power interface and the communication interface in the interface socket 3 through the connector 4 transmit electrical signals to the electrical components in the steering structure, which can drive the micro servo motor 11 to drive the U-shaped part 12 to flip. At this time, the U-shaped part 12 can drive the antenna body 2 to flip and rotate on the outer ring side of the connector 4 through the horizontal shaft part 13 and the connecting rod 15, so that the antenna body 2 can adjust the angle in the two-dimensional space parallel to the end face of the connector 4. At the same time, since the force arm rod 17 is rotatably connected to the outer wall of the side surface of the vertical cylinder 14, when the horizontal shaft part 13 and the vertical cylinder 14 as a whole flip with the U-shaped part 12, it does not affect the connection state between the vertical cylinder 14 and the force arm rod 17. During the process of driving the micro servo motor 11 and driving the antenna body 2 to flip through the U-shaped part 12, the horizontal shaft part 13 and the connecting rod 15, the micro servo motor 2 19 can also be driven to drive the flip rod 16 to flip, that is, the flip rod 16 generates a transmission force on the vertical cylinder 14 through the force arm rod 17. When the force arm rod 17 is inclined, it can cause the horizontal shaft part 13 and the connecting rod 15 to rotate on their own in the U-shaped part 12, thereby driving the antenna body 2 to adjust the angle in the two-dimensional space perpendicular to the end face of the connector 4. The connection of the horizontal shaft part 13, the vertical cylinder 14, the flip rod 16 and the force arm rod 17 can enable the antenna body 2 to be adjusted at any angle in the three-dimensional space, so as to complete the physical angle adjustment of the antenna body 2 to adjust the direction of the beam by changing the phase or amplitude of the internal components. By optimizing the direction of the antenna body 2, the signal propagation path can be made smoother, reducing the attenuation and interference of the signal during the propagation process, thereby improving the network speed.

[0065] During the process of adjusting the direction angle of the antenna body 2, by making the sum of half the length of the horizontal shaft member 13 and the length of the connecting rod 15 greater than the straight-line length from the center point of the horizontal shaft member 13 to the side corner of the connector 4, it can be ensured that during the process of the horizontal shaft member 13 and the connecting rod 15 driving the antenna body 2 to flip and adjust, the circumferential movement trajectory range of the antenna body 2 is greater than the end face range of the connector 4, thereby avoiding the situation of the antenna body 2 colliding with the outer surface of the connector 4, improving the practicability of the fixing device for WIFI antenna adjustment and the rationality of the component operation process. At the same time, by arranging densely arranged ball card slots 8 on both inner walls of the corresponding annular groove 7 of the connector 4, and rotating and clamping ball bodies 9 protruding from the side inner wall of the annular groove 7 in each group of ball card slots 8, the outer surface of the connecting rod 15 is in sliding contact with the two side ball bodies 9 in the annular groove 7, which can improve the smoothness of the rotation of the connecting rod 15 during the process of the connecting rod 15 driving the antenna body 2 to flip along the annular groove 7, thereby further improving the practicability of the fixing device for WIFI antenna adjustment and the component operation processability.

[0066] By arranging multiple groups of interface sockets 3 on the top of the WIFI router 1, when the antenna body 2 is in the vertical state, when driving the micro servo motor two 19 to drive the flipping rod 16 and the force arm rod 17 to drive the vertical cylinder 14, the horizontal shaft member 13 and the connecting rod 15 can drive the antenna body 2 to flip and fold towards the top of the WIFI router 1, which is beneficial to the overall storage and placement of the WIFI router 1 and the antenna body 2.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
