Description

Technical Field

[0001] This application relates to the field of remote control technology, specifically to a multi-frequency antenna remote control. Background Technology

[0002] Existing drone remote controllers typically have an antenna structure for transmitting and receiving signals, which enables wireless communication between the remote controller and the drone's airborne terminal.

[0003] Currently, most remote controllers typically only have antennas for one frequency band, such as the 2.4GHz or 5.8GHz band. This makes the signal easily interfered with by the 2.4GHz or 5.8GHz signals of the router, causing signal loss and potentially leading to drone crashes. Adding multi-frequency antennas, on the other hand, would result in a complex antenna structure and an unsightly, cluttered appearance for the remote controller. Utility Model Content

[0042] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0043] This application proposes a multi-frequency antenna remote controller. The specific structure of the multi-frequency antenna remote controller according to the embodiments of this application will be described below with reference to the accompanying drawings.

[0044] Reference Figures 1-3 The multi-frequency antenna remote controller 100 includes a housing 10, an external antenna assembly 20, an internal antenna assembly 30, and an image transmission PCB board 40. The housing 10 includes a front shell 11 and a rear shell 12, which are interlocked to form a cavity 13 within the housing 10. The external antenna assembly 20 is disposed on the top of the housing 10, and the internal antenna assembly 30 is clamped and disposed on the top of the cavity 13. The external antenna assembly 20 and the internal antenna assembly 30 have different transmission frequency bands. The image transmission PCB board 40 is disposed within the cavity 13, and the external antenna assembly 20 and the internal antenna assembly 30 are electrically connected to the image transmission PCB board 40 via feed lines (not shown in the figure).

[0045] By arranging external antenna components 20 and internal antenna components 30 with different transmission frequency bands on the remote control, on the one hand, when the signal of a certain frequency band emitted by the image transmission PCB board 40 is lost and a disconnection occurs, the image transmission PCB board 40 can re-emit signals of different frequency bands for communication, thus solving the problem of sending signals to the controlled device even when a certain frequency band signal is lost, and the antenna signal is not easily interfered with; on the other hand, the structural layout of the antenna is simplified by the structural design of the external and internal antennas, reducing the structural cost, and the overall remote control is also more aesthetically pleasing.

[0046] In one specific embodiment, the external antenna assembly 20 includes a first external antenna 21 and a second external antenna 22, which are symmetrically arranged on both sides of the top of the housing 10. The first external antenna 21 transmits at a frequency of 1.4 GHz or 2.4 GHz, and the second external antenna 22 also transmits at a frequency of 1.4 GHz or 2.4 GHz. That is, signals in the 1.4 GHz and 2.4 GHz frequency bands can be transmitted using both the first external antenna 21 and the second external antenna 22. The internal antenna assembly 30 includes at least a first internal antenna 31, which transmits at a frequency of 5 GHz.

[0047] In this embodiment, two sets of first built-in antennas 31 are symmetrically arranged on both sides of the cavity 13. By setting two sets of first built-in antennas 31 in the same transmission frequency band, the signal strength can be further improved.

[0048] It is understood that in other embodiments, the number of external antennas may be one or more, and the transmission frequency band of the external antennas may be any one of the frequency bands such as 1.4G, 2.4G, 5G, 5.8G, etc.; the number of internal antennas may be one or more, and the transmission frequency band of the internal antennas may also be any one of the frequency bands such as 1.4G, 2.4G, 5G, 5.8G, etc., without limitation here.

[0049] Reference Figure 3 and Figure 4 In one specific embodiment, a mounting plate 14 is formed on the top of the interior of the front shell 11. The first built-in antenna 31 includes a transmitting plate 311 and a reflector plate 312, which are mounted on the mounting plate 14. When the transmitting plate 311 transmits a signal, both its upper and lower sides transmit signals simultaneously. The upper side transmits directly outward, while the lower side transmits towards the reflector plate 312. The signals are then reflected by the reflector plate 312 and transmitted outward again, thereby enhancing the transmitted signal.

[0050] Specifically, the mounting plate 14 has two first slots 141 arranged vertically along the horizontal direction. The mounting plate 14 on the upper and lower sides of the upper first slot 141 is also formed with clamping parts 142. One side of the emitting plate 311 and the reflector plate 312 are inserted into the first slot 141 and clamped and fixed by the two clamping parts 142.

[0051] Reference Figure 4 and Figure 5 In one specific embodiment, the mounting plate 14 has multiple through holes 143, and each clamping part 142 is formed between two adjacent through holes 143. By opening through holes 143 on the mounting plate 14, the clamping part 142 becomes lower and more flexible, thereby clamping the emitting plate 311 and the reflector plate 312 more stably.

[0052] Continue to refer to Figure 2 In one specific embodiment, the rear shell 12 is provided with a second slot (not shown in the figure). When the front shell 11 and the rear shell 12 are spliced ​​and fitted together, the other side of the emitting plate 311 and the reflector plate 312 are inserted into the second slot. Thus, the first slot 141 on the mounting plate 14 of the front shell 11 and the second slot of the rear shell 12 form a clamping effect on both sides of the emitting plate 311 and the reflector plate 312, making the emitting plate 311 and the reflector plate 312 more stably installed.

[0053] Continue to refer to Figure 2 In one specific embodiment, the multi-frequency antenna remote controller 100 also includes a sealing ring 50, which is circumferentially disposed between the front shell 11 and the rear shell 12 to seal the splicing gap between the front shell 11 and the rear shell 12, preventing water droplets or water vapor from entering the cavity and affecting the first built-in antenna 31.

[0054] In this embodiment, the sealing ring 50 is made of waterproof silicone.

[0055] Reference Figure 6 and Figure 7 In one specific embodiment, both the first external antenna 21 and the second external antenna 22 include a rotating component 211, a folding component 212, an antenna 213, and an antenna housing 214. One end of the rotating component 211 is rotatably fixed to the top of the front housing 11 via a threaded connection, and the other end is rotatably connected to the folding component 212. The other end of the folding component 212 is hinged to the antenna housing 214. An insertion hole 2141 is provided inside the antenna housing 214 along its length. One end of the antenna 213 passes through the rotating component 211 and the folding component 212, and the other end is inserted into the insertion hole 2141. Both the first external antenna 21 and the second external antenna 22 can be folded and stored on the top of the housing 10.

[0056] In one specific embodiment, the structure of the first external antenna 21 and the second external antenna 22 further includes a sealing plug 215, which is inserted into the antenna housing 214 at the opening of the socket 2141. The sealing plug 215 can prevent water droplets or moisture from entering the socket 2141 and affecting the antenna 213.

[0057] In one specific embodiment, the structure of the first external antenna 21 and the second external antenna 22 further includes an elastic sleeve 216, which is sleeved on the antenna 213. One end of the elastic sleeve 216 abuts against the sealing plug 215, and the other end is fixedly connected to the folding member 212.

[0058] When the first external antenna 21 / second external antenna 22 is folded and stored, the antenna housing 214 needs to be rotated. During this process, the antenna 213 will be pulled outward to a certain extent within the socket 2141. The antenna 213 may cause the sealing plug 215 to disengage from the socket 2141, resulting in poor sealing performance of the sealing plug 215. Therefore, by fitting an elastic sleeve 216 onto the antenna 213 between the folding piece 212 and the antenna housing 214, the elastic sleeve 216 is compressed during the rotation of the antenna housing 214, thereby pressing the sealing plug 215 against the opening of the socket 2141 to ensure waterproofing.

[0059] In one specific embodiment, the elastic sleeve 216 is a waterproof sleeve, which also has a waterproof effect.

[0060] In this embodiment, the sealing plug 215 is made of waterproof silicone, and the elastic sleeve 216 is made of heat-shrink silicone tubing.

[0061] In summary, this application proposes a multi-frequency antenna remote controller 100. By setting an external antenna shared by the 1.4G / 2.4G transmission bands and an internal antenna for the 5G transmission band, it can switch to other frequency bands for communication even when the signal of a certain frequency band emitted by the image transmission PCB board 40 is lost. This solves the problem of transmitting signals to the controlled device even when a signal of a certain frequency band is lost, and the antenna signal is not easily affected by interference. At the same time, the structure of the external and internal antennas is simple, which not only reduces the structural cost but also makes the remote controller more aesthetically pleasing.

[0062] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
