DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The UAV image transmission system is a wireless electronic transmission device that uses appropriate video compression technology, signal processing technology, channel coding technology and modulation and demodulation technology to wirelessly transmit the video images captured by the gimbal camera on the scene to the distance behind in real time. The UAV data transmission is a wireless data transmission during the flight of the UAV to realize the functions of sending UAV control signals and returning flight attitude data.

[0039] In the related art, the image transmission and data transmission of the drone are two independent wireless devices. The installation of the two devices on the drone also brings a lot of inconvenience to the structural design of the drone. Based on this, a miniaturized drone image and data transmission integrated device is needed to meet the communication data link requirements of the drone.

[0040] Figure 1 : is a schematic diagram of the three-dimensional exploded structure of the drone image and data transmission integrated device according to the embodiment of the utility model. Figure 1As shown, the drone image and digital transmission integrated device of the exemplary embodiment of the utility model includes an image and digital transmission integrated module, a filter and a shell 10, and the image and digital transmission integrated module and the filter are arranged in the cavity of the shell 10; the image and digital transmission integrated module includes an image transmission module 21, a digital transmission module 22 and a substrate 23, the image transmission module 21 and the digital transmission module 22 are both arranged on the substrate 23, and the image and digital transmission module is communicatively connected with the filter; the first preset plane of the filter is coplanar with the second preset plane of the image and digital transmission integrated module, and the first preset plane refers to: the plane of the cover plate 40 of the filter facing the cavity; the second preset plane refers to: the highest point protruding from the substrate 23 in the image transmission module 21 and the digital transmission module 22, and parallel to the plane of the substrate 23.

[0041] In actual applications, the image transmission module 21 and the digital transmission module 22 are arranged on the same substrate 23 to form an integrated image and digital transmission module, that is, a circuit board, which avoids the complex installation caused by the use of two independent image transmission systems and digital transmission systems, as well as the problems of increased volume and weight of the overall device. The filter, the digital transmission module 22 and the image transmission module 21 are arranged in sequence on the same plane. Specifically, the first preset plane of the filter facing the cover plate 40 is coplanar with the second preset plane of the integrated image and digital transmission module, so that the cover plate 40 can fit the filter and the integrated image and digital transmission module on the shell to form a closed cavity, and the internal space of the cavity is fully utilized, which is conducive to reducing the volume of the overall device, especially thinning the thickness. The above-mentioned cover plate 40 fits the integrated image and digital transmission module means that for the components of the image transmission module 21 and the digital transmission module 22, the top of the highest component fits on the cover plate 40.

[0042] The filter can be regarded as a module in the signal processing system, which can change the spectral characteristics of the input signal. By selectively transmitting or suppressing signal components of specific frequencies, the filter can accurately adjust and modify the signal. The filter of the exemplary embodiment of the utility model is connected to the integrated image and digital transmission module, and the data of the integrated image and digital transmission module will be processed by the filter. For example, the signal is modulated and demodulated, frequency selected and anti-interference processed, and then selectively receives or sends signals in a specific frequency range to improve communication quality and reliability.

[0043] Considering that the image transmission module 21 and the data transmission module 22 may interfere with each other in terms of signals, and thus cannot achieve long-distance, low-latency image transmission and data transmission, a lot of effort will be spent on the selection. Based on this, the drone image and data transmission integrated device of the exemplary embodiment of the utility model also includes a shielding cover 30 abutting against the substrate 23, and the shielding cover 30 has multiple shielding chambers; at least one of the multiple shielding chambers is used to accommodate components of the image transmission module 21, and at least another of the multiple shielding chambers is used to accommodate components of the data transmission module 22; the surface of the shielding cover 30 facing the cover plate 40 is coplanar with the first preset plane.

[0044] In practical applications, the shielding cover 30 is a cover structure that is inverted on the substrate 23, and a plurality of shielding cabins are arranged inside the shielding cover 30. The arrangement and number of the shielding cabins are determined according to the positions of the components that need to be shielded in the image transmission module 21 and the data transmission module 22. For example, the shielding cover 30 has two shielding cabins, one of which is used to accommodate and seal some components of the image transmission module 21, and the other is used to accommodate and seal some components of the data transmission module 22; when different components on the same module need to be shielded, shielding cabins are arranged at the corresponding positions of the shielding cover 30 for each component that needs to be shielded. Since the surface of the shielding cover 30 facing the cover plate 40 is coplanar with the first preset plane, when the shielding cover 30 is arranged on the substrate 23, the cover plate 40 will be pressed against the substrate 23 when it is covered on the housing 10 to form a closed shielding cabin to prevent interference between the signals of each module.

[0045] Figure 5 Schematic diagram of the cross-sectional structure of the drone image and data transmission device according to the embodiment of the utility model. Figure 1 and Figure 5 As shown, the cavity includes a first cavity 131 and a second cavity 132, the integrated digital transmission module is arranged in the first cavity 131, and the filter is arranged in the second cavity 132; the cover plate 40 is covered on the first cavity 131; the cavity is divided into the first cavity 131 and the second cavity 132 by a partition, and the partition is integrally formed with the shell 10; the partition includes a first plate 111 and a second plate 112, the first plate 111 is coplanar with the second preset plane, and the second plate 112 is perpendicular to the first plate 111.

[0046] When the housing 10 is processed, the partition is formed integrally with it. The filter is generally a rectangular parallelepiped and its thickness is greater than the integrated image and digital transmission module. Therefore, the second chamber 132 formed on the housing 10 is in the shape of a rectangular parallelepiped. The first plate 111 and the second plate 112 forming the partition form a step-like shape with the bottom wall 12 of the first chamber 131, so that the first plate 111 is coplanar with the second preset plane, saving space. On the other hand, compared with setting the filter and the integrated image and digital transmission module in one cavity, the partition integrally formed in the housing 10 can be used as the metal shell of the filter, eliminating the process of remaking the metal shell of the filter. At the same time, no additional space is needed to support the installation of the metal shell of the filter, which is conducive to reducing the volume and weight of the entire device.

[0047] Figure 7 This is a schematic diagram of the three-dimensional decomposition structure of the drone image and data transmission integrated device according to another perspective of the embodiment of the utility model. Figure 1 , Figure 5 and Figure 7As shown, the integrated image and digital transmission device also includes a radiator 50, which is located in a heat dissipation cavity 53 formed on the shell 10; the heat dissipation cavity 53 is located on the side of the bottom wall 12 of the first chamber 131 away from the cover plate 40, and the heat dissipation cavity 53 is opposite to at least part of the image transmission module 21.

[0048] The heat dissipation cavity 53 is located at one end of the shell 10 away from the second chamber 132, and is located below the bottom wall 12 of the first chamber 131. Since the integrated image and digital transmission module is supported above the bottom wall 12, and the image transmission module 21 generates the most heat compared to other modules, it is easier to achieve overall heat dissipation by dissipating the radiator 50 below the area with higher heat generation.

[0049] In some embodiments, after the cover plate 40 is crimped onto the shielding cover 30 to seal the cavity, the substrate 23 is crimped onto the bottom wall 12 of the first chamber 131 through the shielding cover 30, so as to facilitate the heat of the substrate 23 to be transferred to the bottom wall 12 and dissipated to the outside of the first chamber 131. In order to further increase the heat conduction between the substrate 23 and the bottom wall 12, a heat conductive layer is further provided between the two to facilitate heat dissipation.

[0050] For example, the back bright copper area of ​​the substrate 23 is coated with heat dissipation silicone grease, and a heat conductive pad is arranged on the back part of the substrate 23 corresponding to the components with high heat generation on the substrate 23, so as to form the above-mentioned heat conductive layer. For example, a heat conductive plate 24 is also welded on a part of the back of the substrate 23 to help conduct heat to the housing for heat dissipation.

[0051] Figure 2 This is a schematic diagram of the structure of the drone image and data transmission integrated device according to the embodiment of the utility model from a bottom view; Figure 3 It is a side view structural schematic diagram of the drone image and data transmission integrated device according to the embodiment of the utility model; Figure 4 : is a schematic diagram of the main structure of the drone image and data transmission device according to the embodiment of the utility model. Figure 2-Figure 4 As shown, the integrated image and digital transmission device of the exemplary embodiment of the utility model also includes a plurality of heat dissipation teeth 52 formed at the bottom of the shell 10, and a heat dissipation channel is formed between two adjacent heat dissipation teeth 52; at least one heat dissipation channel is connected to the heat dissipation cavity 53 and extends along a preset direction, and the preset direction refers to: the distribution direction from the integrated image and digital transmission module to the filter.

[0052] In actual application, the heat dissipation teeth 52 are integrally formed with the bottom plate, and the bottom plate at least covers the opening of the second chamber 132, that is, the bottom plate closes the second chamber 132, and as a whole, it can also serve as a part of the base of the housing. One end of each heat dissipation channel is connected to the heat dissipation cavity 53 close to the right end face of the housing 10, and is parallel to the cover plate 40, and the other end extends toward the direction of the filter until the left end face of the housing 10 (left and right refer to Figure 2Based on this, when the radiator is a fan, the multiple heat dissipation channels formed on the bottom surface of the housing 10 form an airflow from left to right or from right to left under the drive of the fan, and remove the heat generated inside the entire integrated image and digital transmission device, forming a good heat dissipation effect.

[0053] like Figure 1 As shown, the bottom of the heat dissipation cavity 53 is also covered with a fan guard 51 to protect the fan, and the fan guard 51 has a hollow structure for airflow to enter and exit the heat dissipation cavity 53. When the airflow direction of the fan is toward the bottom wall 12, that is, when it blows toward the bottom wall 12, the airflow is sucked in from the hollow structure of the fan guard 51, and flows to the left through the heat dissipation flow channel until it is blown out from the left end surface of the housing 10. Since the image transmission module 21 has the largest heat generation, the data transmission module 22 has the second largest heat generation, and the filter has a smaller heat generation, the airflow flows from the image transmission module 21 to the data transmission module 22 to the filter in sequence, so that the heat dissipation effect of the fan is better.

[0054] Ultra-small Push-on Coaxial Connector (SMP) connectors are used for highly shielded, very small interconnects, and are typically used in miniaturized high-frequency coaxial modules and high data rate applications such as antennas, broadband installations, test and measurement, and quantum computing. SMP connectors are push-in and bite-in plug-in connectors with a minimum installation density of 4.3mm between connector centers, making them ideal for high-density blind mating. They are especially suitable for high-density blind mating between circuit boards, chassis, and cabinets.

[0055] Figure 6a is a schematic diagram of the main structure of the SMP connector according to an embodiment of the utility model; Figure 6b It is a schematic diagram of the main structure of the blind insertion rod according to the embodiment of the utility model; Figure 6c 1 is a schematic diagram of the front view structure of another SMP connector according to an embodiment of the present utility model. Figure 1 , Figure 6a-6b As shown, the filter and the data transmission module 22 are communicatively connected via a coaxial connector 60 , and the coaxial connector 60 includes an SMP connector.

[0056] Specifically, the coaxial connector 60 of the exemplary embodiment of the utility model is composed of a first connector 61, a second connector 63, and a blind plug rod 62 that can be blindly plugged into the first connector 61 and the second connector 63, wherein the first connector 61 and the second connector 63 are both SMP connectors that comply with MIL-STD 348, 326-1 to -5 standards. The first connector 61 is connected to the data transmission module 22 for communication, and the second connector 63 is connected to the filter for communication. Based on this, the use of the above-mentioned SMP connector can make the communication connection between the filter and the data transmission module 22 reliable, while not taking up too much space, and being compact and light in weight.

[0057] In some embodiments, a sealing ring is further provided between the cover plate 40 and the housing 10. The cover plate 40 is pressed onto the opening of the first chamber 131 by screws, and the sealing ring can be used to seal the first chamber 131, so that the device reaches the IP65 grade. IP is the abbreviation of Ingress Protection. The IP grade is the protection level of the housing of electrical equipment against the intrusion of foreign objects, such as: explosion-proof electrical appliances, waterproof and dustproof electrical appliances, and the source is the International Electrotechnical Commission's standard IEC 60529; in this standard, for the protection of the housing of electrical equipment against foreign objects, the format of the IP grade is IPXX, where XX is two Arabic numerals, the first marked number indicates the contact protection and foreign object protection level, and the second marked number indicates the waterproof protection level, and the larger the number, the better the protection level. The first X of 6 indicates that the dustproof level is completely prevented from entering, and the second X of 5 indicates that the waterproof level is unaffected by low-pressure spraying at any angle.

[0058] The exemplary embodiment of the utility model further provides a drone, comprising a fuselage and the above-mentioned drone image and data transmission integrated device, wherein the drone image and data transmission integrated device is arranged on the fuselage. It should be noted that the drone image and data transmission integrated device can be directly or indirectly arranged on the fuselage. When the drone image and data transmission integrated device is indirectly arranged on the fuselage, it can be arranged on the landing gear, arm or frame of the drone and other components connected to the fuselage.

[0059] like Figure 1 and Figure 2 As shown, the UAV image and data transmission integrated device also includes a J30J connector connected to the image transmission module to communicate with the flight control unit of the UAV. At the same time, the fan of the UAV image and data transmission integrated device is also connected to a power connector to connect to the power supply unit of the UAV.

[0060] Compared with the prior art, the advantages of the drone of the exemplary embodiment of the utility model are the same as the advantages of the above-mentioned drone image and data transmission device, which will not be repeated here.
