Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a retractable reflector-assisted 5G antenna structure. Background Art

[0002] Intelligent metasurfaces, also known as reconfigurable intelligent surfaces or intelligent reflecting surfaces, abbreviated as dynamic RIS, can be used as reflectors to assist 5G antennas. By adjusting the absorption, reflection, refraction, and phase of passive reflecting elements in real time, intelligent metasurfaces can flexibly direct incident electromagnetic signals to the desired direction, optimize the propagation path of wireless signals, and thus significantly improve signal quality, coverage, and system performance.

[0003] In response to this, the present application designs a retractable reflector-assisted 5G antenna structure. Most existing dynamic RISs adopt an open and unprotected structure. Although this design has advantages such as low cost, flexible deployment, and good heat dissipation, there are some obvious defects when it comes to outdoor deployment scenarios:

[0004] Since the research and development and production costs of dynamic RISs are relatively high, and they are mostly thin and light structures, most of them are directly deployed using mounting brackets, and the installation stability needs to be improved. At the same time, to reduce external influences, dynamic RISs usually need to be installed in areas with relatively mild environments, which limits their application in complex environments; and after a severe weather warning is issued, to avoid causing a decline in the performance of dynamic RISs or damage to the equipment, workers need to take protective measures for the equipment. If the weather conditions are too severe, the equipment even needs to be temporarily recovered or stopped, and then resumed after the weather improves. The equipment needs to be frequently inspected and maintained, increasing the long-term maintenance cost. Summary of the Invention

[0005] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a retractable reflector-assisted 5G antenna structure, which can effectively solve the problems in the prior art that most of them are directly deployed using mounting brackets, the installation stability needs to be improved, dynamic RISs usually need to be installed in areas with relatively mild environments, which limits their application in complex environments; and after a severe weather warning is issued, to avoid causing a decline in the performance of dynamic RISs or damage to the equipment, workers need to take protective measures for the equipment.

An incomplete gear is fixed on the outer wall of the support rod, and rectangular mounting holes are opened at the positions of the multiple incomplete gears corresponding to the upper end of the support slide, and a rack is installed in the rectangular mounting holes.

[0012] Furthermore, the triangular support group also includes a support bracket installed on the outer wall of the incomplete gear at the tooth gap. Magnets are embedded on both ends of the support bracket away from the incomplete gear, and magnets are also embedded on the upper sides of the inner walls of the left and right ends of the rectangular avoidance hole.

[0013] Furthermore, the snap-in group includes snap-in rods installed at the lower ends of the dynamic RIS body reflection panel and the back panel, and two front and rear rectangular slots are provided at the positions of the front and rear snap-in rods corresponding to the upper end of the support slide. The outer walls of the front and rear snap-in rods are movably fitted on the inner walls of the corresponding rectangular slots respectively, and an accommodating groove is provided on the inner wall of the rectangular slot facing the shorter outer wall of the support slide. The inner wall of the accommodating groove is slidably connected to a wedge-shaped clamping plate at one end facing the shorter outer wall of the support slide through a compression spring, and the wedge-shaped clamping plate is movably pressed against the corresponding snap-in rod.

[0014] Furthermore, the clamping group also includes a rectangular connecting groove jointly opened between the front and rear accommodating slide grooves, a wedge-shaped contact plate is slidably installed in the rectangular connecting groove, and the front and rear ends of the wedge-shaped contact plate are respectively fixedly connected to the corresponding wedge-shaped clamping plate.

The multiple incomplete gears will drive the corresponding support legs to rotate in the opposite direction synchronously until the multiple support legs are away from the incomplete gear and rotate into the corresponding rectangular avoidance holes. At this time, the protective box will be transformed into a closed state, thereby achieving the effect of physical protection for the dynamic RIS body. Even if the weather conditions are too severe, there is no need for staff to temporarily recover or stop the equipment, reducing the frequent inspection and maintenance of the dynamic RIS body and reducing long-term maintenance costs.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] Embodiment:

[0039] Among them, the telescopic support part 5 includes a lead screw 51 rotatably mounted at the bottom end of the protection box 2 through a circular mounting hole, the upper end of the lead screw 51 is threadedly connected to the support slider 4, a hand wheel 52 is mounted at the lower end of the lead screw 51, and a triangular support group 53 is jointly provided on the protection box 2 and the support slider 4;

[0040] Among them, the clamping part 6 includes circular chutes symmetrically opened at the upper end of the support slider 4 on the left and right, contact slide bars 61 are symmetrically mounted on the inner walls of the upper ends of the left and right of the protection box 2, the outer walls of the left and right two contact slide bars 61 are respectively movably attached to the inner walls of the corresponding circular chutes, and clamping groups 62 are provided at the positions corresponding to the left and right two circular chutes on the support slider 4.

[0041] The triangular support group 53 includes rectangular avoidance holes opened at both the front and rear ends of the protection box 2. At the lower sides of the inner walls at both the left and right ends of multiple rectangular avoidance holes, support rods 531 are rotatably installed together. An incomplete gear 532 is fixedly sleeved on the outer wall of the support rod 531. At the positions corresponding to the multiple incomplete gears 532 on the upper end of the support slide 4, rectangular installation holes are opened, and a rack 535 is installed in the rectangular installation holes.

[0042] The triangular support group 53 further includes support brackets 533 installed at the tooth gap positions on the outer wall of the incomplete gear 532. At both the left and right ends of the side of the support bracket 533 away from the incomplete gear 532, magnets 534 are embedded, and magnets 534 are also embedded at the upper sides of the inner walls at both the left and right ends of the rectangular avoidance holes.

[0043] The clamping group 62 includes clamping rods 621 installed at both the reflection panel and the lower end of the back panel of the dynamic RIS body 3. At the positions corresponding to the front and rear two clamping rods 621 on the upper end of the support slide 4, two front and rear rectangular slots are opened. The outer walls of the front and rear two clamping rods 621 are respectively in active contact with the inner walls of the corresponding rectangular slots. At one end of the inner wall of the rectangular slot facing the shorter outer wall of the support slide 4, a receiving chute is opened. At one end of the inner wall of the receiving chute facing the shorter outer wall of the support slide 4, a wedge-shaped clamping plate 622 is slidably connected through a compression spring, and the wedge-shaped clamping plate 622 is in active contact with the corresponding clamping rod 621.

[0044] The clamping group 62 further includes a rectangular communication groove opened between the front and rear two receiving chutes. A wedge-shaped contact plate 623 is slidably installed in the rectangular communication groove, and the front and rear ends of the wedge-shaped contact plate 623 are respectively fixedly connected to the corresponding wedge-shaped clamping plates 622.

[0045] An installation sleeve plate 11 is installed at the upper end of the installation bracket 1. An installation chute is opened at the front end of the installation sleeve plate 11. A convex-shaped slide plate 12 is slidably connected through a compression spring in the installation chute. At the position corresponding to the dynamic RIS body 3 at the upper end of the convex-shaped slide plate 12, an avoidance slide hole is also opened. The outer wall of the dynamic RIS body 3 is in active contact with the inner wall of the avoidance slide hole on the convex-shaped slide plate 12, and a triangular inclined groove communicating with the avoidance slide hole is opened at the lower end of the convex-shaped slide plate 12.

[0046] A rectangular communication hole communicating with the avoidance slide hole is opened at the front end of the convex-shaped slide plate 12. A cleaning cross plate 13 is installed together on the inner walls at both the left and right ends of the rectangular communication hole. The rear end of the cleaning cross plate 13 is in active contact with the reflection panel of the dynamic RIS body 3.

[0047] Filling cross plates 7 are installed at both the upper and lower ends of the reflection panel of the dynamic RIS body 3. Multiple drain holes are opened at the bottom end of the protection box 2.

[0048] During specific implementation:

[0049] First, select a suitable installation location according to the signal coverage target area to ensure that the dynamic RIS body 3 can effectively reflect signals and avoid the installation location being blocked by large obstacles. Then, after fixing the installation bracket 1 at a suitable position, adjust the protection box 2 and the installation bracket 1 to a suitable height and install and connect them. Then, the equipment inspection work can be carried out. It should be noted that the dynamic RIS body 3 is initially in a retracted state inside the protection box 2. At this time, the upper end face of the dynamic RIS body 3 is flush with the upper end face of the protection box 2. And under the action of the compression spring, the convex-shaped slide plate 12 initially extends out of the installation sleeve plate 11, so as to achieve the effect of physically protecting the dynamic RIS body 3. The use of the retractable dynamic RIS body 3 can also avoid the problem that the reflection panel of the dynamic RIS body 3 is easily damaged during transportation and installation.

[0050] When it is necessary to control the dynamic RIS body 3 to extend to regulate the wireless channel work, it should be noted that the dynamic RIS body 3 is initially clamped on the support slide 4 through the clamping group 62. At this time, multiple clamping rods 621 are respectively inserted into the corresponding rectangular slots, and multiple wedge-shaped clamping plates 622, under the action of the compression spring, closely fit against the side walls of the corresponding ends of the clamping rods 621 to limit and press them tightly. First, the installer manually rotates the handwheel 52, and the handwheel 52 will drive the lead screw 51 to rotate synchronously. The lead screw 51 will drive the support slide 4 to move upward through screw transmission. The support slide 4 will drive the dynamic RIS body 3 to move upward. During this period, the upper end of the dynamic RIS body 3 will squeeze the inner wall of the triangular inclined groove on the lower end face of the convex-shaped slide plate 12, causing it to move backward and retract into the installation sleeve plate 11, so as to achieve the effect that the dynamic RIS body 3 smoothly moves upward along the inner wall of the avoidance slide hole on the convex-shaped slide plate 12 and extends out of the protection box 2 until the working end face of the reflection panel of the dynamic RIS body 3 is completely located above the protection box 2. At this time, the lower ends of the left and right contact slide rods 61 will respectively be inserted into the corresponding circular chutes and located above the corresponding clamping groups 62. And it should be noted that the cleaning end face of the cleaning cross plate 13 is a cleaning soft cloth to avoid damaging the surface of the reflection panel of the dynamic RIS body 3. After the convex-shaped slide plate 12 moves backward and retracts into the installation sleeve plate 11, the cleaning cross plate 13 will be movably attached to the reflection panel of the dynamic RIS body 3, and as the dynamic RIS body 3 continues to move upward, the cleaning cross plate 13 will clean the reflection panel of the dynamic RIS body 3.

[0051] Meanwhile, during the period when the lead screw 51 drives the support slide 4 to move upward through screw drive, the support slide 4 will drive multiple racks 535 to move upward synchronously. It should be noted that multiple support feet 533 are initially located in corresponding rectangular avoidance holes respectively, and the magnets 534 on multiple support feet 533 are initially in a magnetic attraction state with the magnets 534 embedded in the rectangular avoidance holes. When multiple racks 535 move upward synchronously and pass through the corresponding incomplete gears 532, each corresponding rack 535 will mesh with the corresponding incomplete gear 532, and through the transmission of the rack 535 and the incomplete gear 532, drive multiple incomplete gears 532 to rotate around the corresponding support rods 531. Multiple incomplete gears 532 will drive the corresponding support feet 533 to rotate synchronously until the side of multiple support feet 533 away from the incomplete gears 532 is flush with the installation ground, so as to achieve the effect of strengthening the installation stability of the dynamic RIS body 3 through triangular support by multiple support feet 533, that is, it can be installed and deployed in a relatively complex environment, effectively enhancing the deployment range of the dynamic RIS. In addition, since the dynamic RIS body 3 extends out of the protection box 2, the force-bearing area will increase in a strong wind environment. The additional support by multiple support feet 533 can effectively prevent the reflection angle and installation position of the dynamic RIS body 3 from shifting. At the same time, multiple rectangular avoidance holes designed on the protection box 2 can cleverly guide the wind flow to pass smoothly, thereby effectively reducing part of the resistance.

[0052] After the issuance of a severe weather warning, to prevent a decline in the performance of the dynamic RIS or damage to the equipment, the staff rotates the handwheel 52 in the reverse direction. The handwheel 52 will drive the lead screw 51 to rotate synchronously in the reverse direction. The lead screw 51 will drive the support slide 4 to move downward through screw drive. The support slide 4 will drive the dynamic RIS body 3 to move downward. During this period, the cleaning cross plate 13 will continuously move downward with the dynamic RIS body 3. The cleaning cross plate 13 will clean the reflection panel of the dynamic RIS body 3, removing dust, dirt, and other pollutants that accumulate on the surface of the reflection panel of the dynamic RIS body 3, avoiding affecting its ability to reflect and regulate signals, ensuring long-term stable operation and optimal performance. When the upper end face of the dynamic RIS body 3 returns to be flush with the upper end face of the protection box 2, under the action of the compression spring, the convex-shaped slide plate 12 will extend out of the mounting sleeve plate 11 again and return to its original position. At the same time, during the process that the support slide 4 drives the multiple racks 535 to move downward synchronously and pass through the corresponding incomplete gears 532, each corresponding rack 535 will engage with the corresponding incomplete gear 532, and through the transmission of the rack 535 and the incomplete gear 532, drive the multiple incomplete gears 532 to rotate reversely around the corresponding support rods 531. The multiple incomplete gears 532 will drive the corresponding support brackets 533 to rotate synchronously in the reverse direction until the sides of the multiple support brackets 533 away from the incomplete gears 532 respectively rotate into the corresponding rectangular avoidance holes. At this time, the magnets 534 on the multiple support brackets 533 and the magnets 534 embedded in the rectangular avoidance holes are restored to the magnetic attraction state, and the protection box 2 will change to a closed state, thus achieving the effect of physically protecting the dynamic RIS body 3. Even if the weather conditions are too severe, there is no need for the staff to temporarily recycle or stop the operation of the equipment, reducing the frequent inspection and maintenance of the dynamic RIS body 3 and lowering the long-term maintenance cost.

[0053] When it is necessary to disassemble the dynamic RIS body 3, the staff also manually rotates the handwheel 52. The handwheel 52 will drive the lead screw 51 to rotate synchronously. The lead screw 51 will drive the support slide 4 to move upward through screw thread transmission. The support slide 4 will drive the dynamic RIS body 3 to move upward and extend out of the protection box 2. When the working end face of the reflection panel of the dynamic RIS body 3 is completely located above the protection box 2, the lower ends of the left and right abutting slide rods 61 will be inserted into the corresponding circular chutes respectively and located above the corresponding clamping groups 62. Then continue to rotate the handwheel 52 to control the lead screw 51 to drive the support slide 4 to continue moving upward until the upper end of the support slide 4 is closely attached to the inner wall of the upper end of the protection box 2. During this period, the left and right abutting slide rods 61 will continue to be inserted along the corresponding circular chutes. The left and right abutting slide rods 61 will respectively squeeze the corresponding wedge-shaped abutting plates 623. The left and right wedge-shaped abutting plates 623 will respectively drive the corresponding front and rear wedge-shaped clamping plates 622 to make adaptive sliding compensation along the corresponding rectangular communication grooves, so that the left and right abutting slide rods 61 can move downward smoothly. At this time, the plurality of wedge-shaped clamping plates 622 will respectively move away from the corresponding clamping rods 621, releasing the limit and tightening of the clamping rods 621, thereby achieving the effect of quickly detaching the dynamic RIS body 3 and the support slide 4. The staff can then pull out the dynamic RIS body 3, causing the plurality of clamping rods 621 to withdraw from the corresponding rectangular slots respectively. At this time, under the action of the compression spring, the wedge-shaped clamping plates 622 and wedge-shaped abutting plates 623 on both sides will return to their original positions.

[0054] When it is necessary to install the dynamic RIS body 3, finally the staff places the replaced dynamic RIS body 3 on the support slide 4 and inserts the plurality of clamping rods 621 into the corresponding rectangular slots respectively. The plurality of clamping rods 621 will squeeze the corresponding wedge-shaped abutting plates 623. The left and right wedge-shaped abutting plates 623 will drive the corresponding front and rear wedge-shaped clamping plates 622 to make adaptive sliding compensation along the corresponding rectangular communication grooves, so that the left and right clamping rods 621 can move downward smoothly. Under the action of the compression spring, the wedge-shaped clamping plates 622 and wedge-shaped abutting plates 623 on both sides will return to their original positions and limit and tighten the clamping rods 621 again, thereby achieving the effect of quickly clamping the dynamic RIS body 3 and the support slide 4 through the plurality of clamping rods 621.

[0055] In summary, the present application has the following advantages:

[0056] Advantage 1: When it is necessary to control the dynamic RIS body 3 to extend for regulating the wireless channel operation, first, the installer manually rotates the handwheel 52. The handwheel 52 will drive the lead screw 51 to rotate synchronously. The lead screw 51 will drive the support slider 4 to move upward through screw thread transmission. The support slider 4 will drive the dynamic RIS body 3 to move upward. During this period, the upper end of the dynamic RIS body 3 will squeeze the inner wall of the triangular chute on the lower end face of the convex-shaped slide plate 12, causing it to move backward and retract into the mounting sleeve plate 11, so as to realize the effect that the dynamic RIS body 3 smoothly moves upward along the inner wall of the avoidance slide hole on the convex-shaped slide plate 12 and extends out of the protection box 2. Using the retractable dynamic RIS body 3 can also avoid the problem that the reflection panel of the dynamic RIS body 3 is easily damaged during transportation and installation.

[0057] Advantage 2: During the period when the lead screw 51 drives the support slider 4 to move upward through screw thread transmission, the support slider 4 will drive a plurality of racks 535 to move upward synchronously. Each corresponding rack 535 will mesh with the corresponding incomplete gear 532, and through the transmission of the rack 535 and the incomplete gear 532, drive a plurality of incomplete gears 532 to rotate around the corresponding support rods 531. The plurality of incomplete gears 532 will drive the corresponding support brackets 533 to rotate synchronously until the sides of the plurality of support brackets 533 away from the incomplete gears 532 are flush with the installation ground, so as to realize the effect that the plurality of support brackets 533 strengthen the installation stability of the dynamic RIS body 3 through triangular support, that is, it can be installed and deployed in a relatively complex environment, effectively enhancing the deployment range of the dynamic RIS. In addition, since the force-bearing area of the dynamic RIS body 3 increases in a strong wind environment after it extends out of the protection box 2, additional support by the plurality of support brackets 533 can effectively prevent the reflection angle and installation position of the dynamic RIS body 3 from shifting. At the same time, a plurality of rectangular avoidance holes designed on the protection box 2 can skillfully guide the wind flow to pass smoothly, thereby effectively reducing part of the resistance.

[0058] Advantage 3: After the severe weather warning is issued, to prevent the performance of the dynamic RIS from degrading or the equipment from being damaged, the staff reversely rotates the handwheel 52. The handwheel 52 will drive the lead screw 51 to rotate reversely synchronously. The lead screw 51 will drive the support slide 4 to move downward through screw thread transmission. The support slide 4 will drive the dynamic RIS body 3 to move downward. At the same time, when the support slide 4 drives the multiple racks 535 to move downward synchronously and pass through the corresponding incomplete gears 532, each corresponding rack 535 will engage with the corresponding incomplete gear 532, and through the transmission of the rack 535 and the incomplete gear 532, drive the multiple incomplete gears 532 to rotate reversely around the corresponding support rods 531. The multiple incomplete gears 532 will drive the corresponding support feet 533 to rotate reversely synchronously until the sides of the multiple support feet 533 away from the incomplete gears 532 respectively rotate into the corresponding rectangular avoidance holes. At this time, the magnets 534 on the multiple support feet 533 and the magnets 534 embedded in the rectangular avoidance holes are restored to the magnetic attraction state, and the protection box 2 will change to a closed state, thus achieving the effect of physically protecting the dynamic RIS body 3. Even if the weather conditions are extremely severe, there is no need for the staff to temporarily recycle or stop the operation of the equipment, reducing the frequent inspection and maintenance of the dynamic RIS body 3 and lowering the long-term maintenance cost.

[0059] Advantage 4: During this period, the cleaning cross plate 13 moves downward continuously with the dynamic RIS body 3. The cleaning cross plate 13 will clean the reflection panel of the dynamic RIS body 3, removing the dust, dirt and other pollutants that will accumulate on the surface of the reflection panel of the dynamic RIS body 3, avoiding affecting its ability to reflect and regulate signals, so as to ensure long-term stable operation and optimal performance.

[0060] Advantage 5: When it is necessary to disassemble the dynamic RIS body 3, the staff also manually rotates the handwheel 52 to control the lead screw 51 to drive the support slide 4 to continue moving upward until the upper end of the support slide 4 is closely attached to the inner wall of the upper end of the protection box 2. The left and right contact slide rods 61 will respectively squeeze the corresponding wedge-shaped contact plates 623. The left and right wedge-shaped contact plates 623 will respectively drive the corresponding front and rear wedge-shaped clamping plates 622 to make adaptive sliding compensation along the corresponding rectangular communication grooves, so that the left and right contact slide rods 61 can move downward smoothly. At this time, the multiple wedge-shaped clamping plates 622 will respectively move away from the corresponding clamping rods 621, releasing the limit and tightening of the clamping rods 621, thus achieving the effect of quickly detaching the dynamic RIS body 3 and the support slide 4.

[0061] Advantage Six: When the dynamic RIS body 3 needs to be installed, the staff places the replaced dynamic RIS body 3 on the support sliding seat 4, and inserts the plurality of clamping rods 621 into the corresponding rectangular slots respectively. The plurality of clamping rods 621 will squeeze the corresponding wedge-shaped contact plates 623. The left and right wedge-shaped contact plates 623 will drive the corresponding front and rear wedge-shaped clamping plates 622 to perform adaptive sliding compensation along the corresponding rectangular communication grooves, so that the left and right clamping rods 621 can move downward smoothly. Under the action of the compression spring, the wedge-shaped clamping plates 622 and wedge-shaped contact plates 623 on both sides will return to their original positions and limit and tighten the clamping rods 621 again, thereby realizing the quick clamping effect of the dynamic RIS body 3 and the support sliding seat 4 through the plurality of clamping rods 621.
