[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figure 1 and Figure 2 According to an embodiment of this application, a communication control device 100 includes a housing 10, a circuit board 20, an antenna 30, and a reflective component 40. The housing 10 has a receiving cavity 11 and includes a first sidewall 12 defining a partial boundary of the receiving cavity 11. The circuit board 20 is disposed within the receiving cavity 11; the antenna 30 is disposed within the receiving cavity 11 and electrically connected to the circuit board 20; the reflective component 40 is disposed within the receiving cavity 11, and the reflective component 40 is located on the side of the antenna 30 facing away from the first sidewall 12. The reflective component 40 is configured to reflect the signal of the antenna 30 towards the first sidewall 12.

[0028] When using the communication control device 100 to control the drone, the first sidewall 12 of the housing 10 needs to face the drone to send control commands and receive signal feedback. In this embodiment, the communication control device 100 adds a reflective component 40 inside the housing 10 and places the reflective component 40 on the side of the antenna 30 away from the first sidewall 12. This allows the reflective component 40 to reflect the signal emitted by the antenna 30 towards the first sidewall 12, thereby enhancing the signal strength emitted directionally along the first sidewall 12 and improving the stability of communication between the communication control device 100 and the drone.

[0029] For the housing 10 described above, please refer to... Figure 2 and Figure 3 The housing 10 includes a base 10a and a cover 10b. Along the first direction X, the base 10a has a bottom wall 10a1 and an opening. The base 10a also includes a first sidewall 12 and a second sidewall 13 disposed opposite each other in the third direction Z, and a third sidewall 14 and a fourth sidewall 15 disposed opposite each other in the second direction Y. The third sidewall 14 connects to the first sidewall 12 and the second sidewall 13, and the fourth sidewall 15 connects to the first sidewall 12 and the second sidewall 13, respectively. The first sidewall 12, the second sidewall 13, the third sidewall 14, the fourth sidewall 15, and the bottom wall 10a1 together enclose a receiving cavity 11 and define a portion of the boundary of the receiving cavity 11. The shape of the cover 10b is adapted to the shape of the opening, and the cover 10b is used to close the opening. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. Furthermore, the first direction X corresponds to the thickness direction of the housing 10.

[0030] It is understood that the first sidewall 12 of the housing 10 is a signal radiating wall, and the signals emitted by the antenna 30 and the signals fed back by the drone can penetrate the first sidewall 12. As an example, the housing 10 is made of plastic.

[0031] For the circuit board 20 mentioned above, please refer to... Figure 1 and Figure 4 The circuit board 20 is disposed within the receiving cavity 11. The circuit board 20 is equipped with control circuitry and communication circuitry, enabling signal transmission within the communication control device 100 and establishing communication with the drone. In this embodiment, the structure and function of the circuit board 20 are not specifically limited.

[0032] For antenna 30 mentioned above, please refer to... Figure 4Antenna 30 is disposed within the receiving cavity 11 and electrically connected to the circuit board 20. Antenna 30 is configured to transmit control command signals to the external drone and receive signals fed back by the drone. In some embodiments, antenna 30 includes a single-stage antenna, dipole antenna, loop antenna, helical antenna, parabolic antenna, patch antenna, microstrip antenna, slot antenna, array antenna, etc. As an example, antenna 30 in this embodiment is a helical antenna 30. The helical antenna 30 is electrically connected to the circuit board 20 and forms a ground, and the helical antenna 30 extends helically along the first direction X. The helical antenna 30 has characteristics such as circular polarization, wide bandwidth, and high gain, which can enhance communication stability, strong anti-interference ability, and good directional transmission effect. By using a structure combining the helical antenna 30 and the reflector 40, the directional communication capability and stability of antenna 30 along the first sidewall 12 are further enhanced.

[0033] In some embodiments, please refer to Figure 3 and Figure 4 A fixing part 17 extends from the bottom wall 10a1 of the housing 10 along the first direction X. The position of the fixing part 17 corresponds to the position of the helical antenna 30. The fixing part 17 directly abuts against the helical antenna 30 or is spaced apart from it. The fixing part 17 is configured to fix the helical antenna 30 or reduce the shaking amplitude of the helical antenna 30 during use, thereby improving the communication stability of the helical antenna 30. As an example, the fixing part 17 is a hollow column structure, and a portion of the helical antenna 30 is housed inside the hollow column. The sidewall of the hollow column has the function of fixing and limiting the helical antenna 30. In other examples, the fixing part 17 is a thin plate-shaped or square column-shaped structure.

[0034] For the aforementioned reflective component 40, please refer to... Figure 6 Along the first direction X, the heights H1 and H2 of the reflective component 40 are both greater than the height H3 of the antenna 30, and / or, along the second direction Y, the lengths L1 and L2 of the reflective component 40 are both greater than half the wavelength of the antenna 30. With this structure, the reflective component 40 can effectively reflect signals emitted by the antenna 30 toward the second sidewall 13, reflecting a portion of the signal toward the first sidewall 12 to enhance the communication signal along the direction of the first sidewall 12. As an example, the antenna 30 is an axial-mode helical antenna 30, operating at a frequency of 2.4 GHz, with a pitch and diameter designed according to 1 / 4 wavelength. Along the first direction X, the height H1 of the reflective component 40 is 1.2 times the length H3 of the antenna 30, and along the second direction Y, the length L1 of the reflective component 40 is greater than 120 mm (corresponding to half the wavelength). The reflective component 40 is fixed to the side of the antenna 30 facing away from the first sidewall 12, directionally reflecting the signal toward the first sidewall 12. In some embodiments, the reflective component 40 comprises one of a conductive metal, a conductive coating, or a carbon fiber material. Examples include copper foil, aluminum foil, and carbon fiber sheets.

[0035] In some embodiments, please refer to Figures 2 to 4 The housing 10 has a first baffle 16 extending along the first direction X, and the first baffle 16 is located on the side of the antenna 30 opposite to the first sidewall 12. The communication control device 100 includes an electronic component 50, which is disposed within the receiving cavity 11. The electronic component 50 is electrically connected to the circuit board 20, and the electronic component 50 abuts against the side of the first baffle 16 opposite to the first sidewall 12; the first baffle 16 is used to limit and support the electronic component 50. The electronic component 50 includes a battery, electronic components, etc.

[0036] The reflecting component 40 includes a first conductive element 41, which is disposed on the surface of the electronic component 50 facing the first sidewall 12, or on the outer surface 161 of the first baffle 16 facing the first sidewall 12, or on the inner surface 162 of the first baffle 16 facing away from the first sidewall 12. By disposing of the first conductive element 41 on the side of the antenna 30 facing away from the first sidewall 12, the signal of the antenna 30 can be effectively reflected, enhancing the signal strength on the first sidewall 12. Using the electronic component 50 or the first baffle 16 that fixes the electronic component 50 as a carrier for mounting the first conductive element 41 eliminates the need for an additional mounting carrier and makes reasonable use of the space within the receiving cavity 11.

[0037] In some embodiments, please refer to Figure 2 When only the first conductive element 41 is provided, the first conductive element 41 includes a first segment 411, a second segment 412, and a third segment 413. The first segment 411 and the third segment 413 are respectively connected to the two ends of the second segment 412. The second segment 412 is located on the side of the antenna 30 away from the first sidewall 12. Both the first segment 411 and the third segment 413 extend towards the first sidewall 12 in a curved manner. The first conductive element 41 thus formed has a U-shaped structure, and its opening faces the antenna 30. The U-shaped first conductive element 41 can further reflect the signals from the two sides of the antenna 30 in the second direction Y.

[0038] In some embodiments, please refer to Figure 3 Along the second direction Y, the length of the second sidewall 13 is greater than the length of the electronic component 50; therefore, the length of the first conductive element 41 mounted on the electronic component 50 or the first baffle 16 may not be sufficient to reflect more signals, that is, some signals toward the second sidewall 13 are not successfully reflected by the first conductive element 41.

[0039] Please see Figure 5 and Figure 7The reflecting component 40 also includes a second conductive element 42, which is disposed on the second sidewall 13, i.e., on the side of the first conductive element 41 facing away from the antenna 30. By providing the first conductive element 41 and the second conductive element 42, some signals that were not reflected by the first conductive element 41 can continue to be reflected by the second conductive element 42, thereby enhancing signal reflection along the first sidewall 12 and enhancing the signal directionality on the first sidewall 12.

[0040] In some embodiments, the second conductive element 42 includes a fourth segment 421, a fifth segment 422, and a sixth segment 423. The fourth segment 421 and the sixth segment 423 are respectively connected to the two ends of the fifth segment 422. The fourth segment 421 is disposed on the third sidewall 14, the fifth segment 422 is disposed on the second sidewall 13, and the sixth segment 423 is disposed on the fourth sidewall 15. The second conductive element 42 thus constructed also has a U-shaped structure, and its opening faces the antenna 30. The second conductive element 42, especially the fourth segment 421 and the sixth segment 423, can further reflect the signal of the antenna 30 towards the first sidewall 12. In other embodiments, the fifth segment 422 may be discontinuous, and the fifth segment 422 may avoid the electronic component 50; or in some embodiments, the fifth segment 422 may be omitted.

[0041] Please see Figure 5 and Figure 7 In embodiments where both a first conductive element 41 and a second conductive element 42 are provided, to prevent signals from being reflected again by the first conductive element 41 after being reflected by the second conductive element 42, which would cause signal disturbance and negative impact within the receiving cavity 11, the first segment 411 and the third segment 413 of the first conductive element 41 are both curved and extended away from the first sidewall 12 to cover the two side surfaces of the electronic component 50 in the second direction Y. In this structure, the signal emitted by the antenna 30 towards the first sidewall 12 is transmitted as shown by path M1, and the signal emitted by the antenna 30 towards the electronic component 50 is transmitted as shown by path M2. The signal emitted by the antenna 30 towards the second sidewall 13 can be directly guided to the first sidewall 12 after being reflected by the second conductive element 42, or, as shown by path M3, the signal reflected by the second conductive element 42 is then reflected by the first conductive element 41 and directly guided to the first sidewall 12 without being reflected back to the second conductive element 42, effectively improving the signal reflection path inside the receiving cavity 11.

[0042] It is understood that the communication control device 100 in this application embodiment has a structure that only sets the first conductive element 41, or a structure that sets both the first conductive element 41 and the second conductive element 42. This is beneficial for the signal of the antenna 30 to be emitted from the first side wall 12 as much as possible (such as the direction of the arrows in paths M1, M2, and M3), and also beneficial for receiving the signal fed back by the UAV from the first side wall 12 in a directional manner (such as the opposite direction of the arrows in paths M1, M2, and M3). This can reduce interference from other signals and improve the communication quality between the communication control device 100 and the UAV.

[0043] This application also provides an embodiment of a flight system, which includes a drone and the communication control device 100 described in the above embodiments. The drone and the through-hole control device can establish corresponding communication. The communication control device 100 is used to send control signals to the drone and receive signals fed back by the drone. For the specific structure and function of the floor scrubber, please refer to the above embodiments, which will not be repeated here.

[0044] This application embodiment of the communication control device 100 includes a housing 10, a circuit board 20, an antenna 30, and a reflective component 40. The housing 10 has a receiving cavity 11 and includes a first sidewall 12 defining a partial boundary of the receiving cavity 11. The circuit board 20 is disposed within the receiving cavity 11; the antenna 30 is disposed within the receiving cavity 11 and electrically connected to the circuit board 20; the reflective component 40 is disposed within the receiving cavity 11, located on the side of the antenna 30 facing away from the first sidewall 12, and configured to reflect the signal from the antenna 30 towards the first sidewall 12. In this application embodiment, by adding a reflective component 40 inside the housing 10 and positioning the reflective component 40 on the side of the antenna 30 facing away from the first sidewall 12, the reflective component 40 can reflect the signal emitted by the antenna 30 towards the first sidewall 12, thereby enhancing the signal strength emitted along the first sidewall 12 and improving the stability of communication between the communication control device 100 and the drone.
