Description

Technical Field

[0001] This utility model relates to the field of signal enhancers, and in particular to a signal enhancer for drone remote control. Background Technology

[0002] A drone remote control signal booster is used to improve the transmission range and signal strength of the drone's remote control signal, thereby improving the drone's flight stability and control distance. It usually achieves this function through an external antenna and signal amplifier, which can reduce the possibility of signal interference and loss, and improve flight safety and efficiency.

[0003] Existing drone signal boosters, when compatible with the drone remote control at the same frequency, can only be selected based on the structure that is compatible with the booster's installation. For example, magnetic mounting structures work well for remote controls with metal casings, but not for those with plastic casings. Clip-on mounting structures require a precise match to the remote control's outline and size; if there is a slight deviation, it cannot be securely fixed. Therefore, the existing drone signal boosters have low compatibility.

[0004] To address this, a drone remote control signal enhancer is proposed. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a drone remote control signal enhancer to solve the issues raised in the background section.

[0006] The technical solution of this utility model is:

[0007] A drone remote control signal booster includes a signal amplifier, a gain antenna, and a mounting plate. The gain antenna is fixedly connected to the surface of the signal amplifier, and the mounting plate is hinged to the outside of the signal amplifier. The outer surface of the mounting plate has a fixing opening, and the inner wall of the fixing opening is provided with an adapter mounting assembly. The adapter mounting assembly includes a mounting post fixed to the inner wall of the fixing opening. One end of the mounting post is provided with an adsorption cover, and the interior of the mounting post has a cavity. The inner wall of the cavity is provided with an operating mechanism for vacuum adsorption of the adsorption cover.

[0008] In a further technical solution, a symmetrical shaft pin is fixedly connected to the bottom side wall of the mounting plate, a connecting sleeve is hinged to the outer surface of the shaft pin, a fixing block is fixedly connected to the end of the connecting sleeve away from the shaft pin, a rotating groove is opened on the end face of the fixing block away from the connecting sleeve, a rubber ball is rotatably connected to the inner wall of the rotating groove, and a connecting column is fixedly connected between the rubber ball and the side wall of the signal amplifier.

[0009] Through the above technical solution, by setting the shaft pin and connecting sleeve, the signal amplifier can have the effect of simple hinged angle adjustment. At the same time, by setting a rubber ball at the end of the connecting sleeve and connecting it to the signal amplifier with a connecting post, the signal amplifier can have the effect of multi-angle adjustment. In use, the signal amplifier can be shaken at will, so that the rubber ball rotates on the inner wall of the rotating groove for self-adaptation.

[0010] In a further technical solution, a turning port is provided on the outer side of the opening of the rotating groove, which is located on the end face of the fixed block, and six turning ports are provided.

[0011] The above technical solution allows the connecting post to be positioned close to the opening of the turning port during the angle adjustment of the signal amplifier, maximizing the angle adjustment and avoiding the limitation of the fixed block being merely a flat surface, which restricts the placement area of ​​the connecting post.

[0012] In a further technical solution, the adapter mounting assembly also includes a notch formed on the end face of the mounting column, the inner wall of the notch is fixedly connected to a support cover, the support cover is in communication with the adsorption cover, the support cover is cylindrical, and the bottom end of the adsorption cover is funnel-shaped.

[0013] Through the above technical solution, the structure can provide stable support at the other end of the adsorption hood by relying on the support hood on the inner wall of the recess during adsorption, thus preventing collapse.

[0014] In a further technical solution, the operating mechanism includes a threaded rod connected inside the cavity via a sealed bearing. One end of the threaded rod passes through a mounting post and is fixedly connected to a torsion block. A sealing plug is provided on the inner wall of the cavity near the recess. A threaded opening for threaded connection with the threaded rod is provided at the center of the surface of the sealing plug. Symmetrical rubber blocks are fixedly connected to the outer surface of the sealing plug. Symmetrical sliding grooves are provided on the inner wall of the cavity. Four circumferentially distributed through holes are provided on the end of the support cover away from the adsorption cover. A sealing port communicating with the through holes is provided on the end of the cavity near the recess.

[0015] In a further technical solution, four sealing blocks are fixedly connected to one end of the sealing plug near the sealing opening, and the diameter of the sealing blocks is adapted to the diameter of the sealing opening.

[0016] With the above technical solution, when adsorption is not required, the sealing block can always be inserted into the inner wall of the sealing port to maintain a sealed state with the through hole facing upward, thus preventing dust from entering the cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When using this drone remote control signal booster, simply attach the mounting plate to the surface of the remote control, then rotate the torsion block. This causes the threaded rod, sealing plug, rubber block, and sliding groove to work together in a threaded transmission state. During this process, the sealing plug moves away from the support cover, creating a negative pressure in the cavity towards the sealing opening. This generates suction from the adsorption cover into the cavity, causing the adsorption cover to adhere to the surface of the remote control's housing. This structure allows the signal amplifier to be installed on a remote control of the same frequency without needing to consider a compatible mounting structure. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Example:

[0031] Please see Figure 1-5 A drone remote control signal enhancer includes a signal amplifier 1, a gain antenna 2, and a mounting plate 3. The gain antenna 2 is fixedly connected to the surface of the signal amplifier 1, and the mounting plate 3 is hinged to the outside of the signal amplifier 1. The outer surface of the mounting plate 3 has a fixing opening 4, and the inner wall of the fixing opening 4 is provided with an adapter mounting assembly. The adapter mounting assembly includes a mounting post 5 fixed to the inner wall of the fixing opening 4. One end of the mounting post 5 is provided with an adsorption cover 13, and the interior of the mounting post 5 has a cavity 6. The inner wall of the cavity 6 is provided with an operating mechanism for vacuum adsorption of the adsorption cover 13.

[0032] Please see Figure 1 and Figure 5 A symmetrical shaft pin 19 is fixedly connected to the bottom side wall of the mounting plate 3. A connecting sleeve 20 is hinged to the outer surface of the shaft pin 19. A fixing block 21 is fixedly connected to the end of the connecting sleeve 20 away from the shaft pin 19. A rotating groove 22 is opened on the end face of the fixing block 21 away from the connecting sleeve 20. A rubber ball 23 is rotatably connected to the inner wall of the rotating groove 22. A connecting post 24 is fixedly connected between the rubber ball 23 and the side wall of the signal amplifier 1.

[0033] By setting the shaft pin 19 and the connecting sleeve 20, the signal amplifier 1 can have the effect of simple hinged angle adjustment. At the same time, a rubber ball 23 is set at the end of the connecting sleeve 20 and connected to the signal amplifier 1 by the connecting post 24, so that the signal amplifier 1 can have the effect of multi-angle adjustment. In use, the signal amplifier 1 can be shaken at will, so that the rubber ball 23 rotates on the inner wall of the rotating groove 22 for adaptive adjustment.

[0034] Please see Figure 2 and Figure 5 The outer side of the opening of the rotating groove 22 is provided with a turning port 25 on the end face of the fixed block 21, and there are six turning ports 25.

[0035] This allows the connecting post 24 to be positioned close to the opening of the turning port 25 during the angle adjustment of the signal amplifier 1, maximizing the angle adjustment and preventing the fixed block 21 from being merely a plane, which would limit the placement area of ​​the connecting post 24.

[0036] Please see Figure 3 and Figure 4 The adapter installation component also includes a notch 11 opened on the end face of the mounting column 5. A support cover 12 is fixedly connected to the inner wall of the notch 11. The support cover 12 is connected to the adsorption cover 13. The support cover 12 is cylindrical and the bottom end of the adsorption cover 13 is trumpet-shaped.

[0037] This structure allows the adsorption cover 13 to have a stable support effect on the inner wall of the recess 11 by the support cover 12 during adsorption, thus preventing it from collapsing.

[0038] Please see Figure 3 and Figure 4 The operating mechanism includes a threaded rod 8 connected inside the cavity 6 via a sealed bearing. One end of the threaded rod 8 passes through the mounting post 5 and is fixedly connected to a torsion block 9. A sealing plug 7 is provided at the end of the inner wall of the cavity 6 near the recess 11. A threaded opening 10 is provided at the center of the surface of the sealing plug 7, which is threaded to the threaded rod 8. A symmetrical rubber block 17 is fixedly connected to the outer surface of the sealing plug 7. A symmetrical sliding groove 18 is provided on the inner wall of the cavity 6. Four circumferentially distributed through holes 14 are provided at the end of the support cover 12 away from the adsorption cover 13. A sealing opening 15 communicating with the through holes 14 is provided at the end of the cavity 6 near the recess 11.

[0039] Please see Figure 3 and Figure 4 Four sealing blocks 16 are fixedly connected to one end of the sealing plug 7 near the sealing port 15. The diameter of the sealing block 16 is adapted to the diameter of the sealing port 15.

[0040] When adsorption is not required, the sealing block 16 can always be inserted into the inner wall of the sealing port 15 to keep the through hole 14 in an upward-facing sealed state, preventing dust from entering the cavity 6.

[0041] During operation, mount plate 3 is attached to the surface of the remote control, aligning the fixing port 4 on mount plate 3 with the desired installation position. Rotate the torsion block 9, which drives the threaded rod 8 to rotate. Since the threaded rod 8 and the threaded port 10 of the sealing plug 7 are in a threaded transmission state, the sealing plug 7 will move along the inner wall of the cavity 6 when the threaded rod 8 rotates. The direction of movement of the sealing plug 7 is away from the support cover 12. As the sealing plug 7 moves, the space in the cavity 6 towards the sealing port 15 gradually increases, the air pressure decreases, and a negative pressure is formed. Under the action of the negative pressure, the suction force is generated from the adsorption cover 13 into the cavity 6, and the adsorption cover 13 then firmly adsorbs the air. On the surface of the remote control housing, the initial installation of the signal amplifier 1 on the remote control is completed. When it is necessary to adjust the angle of the signal amplifier 1, it can be simply adjusted by hinged by the symmetrical shaft pin 19 and connecting sleeve 20 on the bottom side wall of the mounting plate 3. The signal amplifier 1 is gently shaken, and the rubber ball 23 at the end of the connecting sleeve 20 will rotate on the inner wall of the rotating groove 22. Relying on the self-adaptive cooperation between the rubber ball 23 and the rotating groove 22, the signal amplifier 1 can be adjusted at multiple angles. During the process, the connecting post 24 can be brought close to the opening of the rotating port 25 to maximize the angle adjustment and meet different usage needs.

[0042] In addition, to release the adsorption, simply rotate the torsion block 9 in the opposite direction, causing the threaded rod 8 to reverse, so that the sealing plug 7 moves towards the support cover 12. The negative pressure in the cavity 6 gradually disappears, and the adsorption cover 13 loses its suction force, so the mounting plate 3 can be removed from the surface of the remote control.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
