Description

Technical Field

[0001] The utility model relates to the technical field of data transmission radios, and particularly to an unmanned aerial vehicle (UAV) data transmission radio with a waterproof structure. Background Technique

[0002] The UAV data transmission radio is an important part of the UAV system, mainly responsible for data transmission between the UAV and the ground station. The UAV data transmission radio includes a rectangular housing and modules such as a radio frequency module, a modem, and a signal processing module arranged therein. The opposite sides of the housing are sealed by metal covers, and the metal covers are connected to the housing by bolts.

[0003] In the prior art, there is a hard contact between the metal cover and the metal housing, and it can only be closely attached at the bolt connection points. However, the other joints between the metal cover and the housing cannot be well fitted. During long-term use, water or water vapor will enter the housing through the gaps between the metal cover and the housing, which will cause corrosion of metal components and solder joints, affecting the connectivity and long-term reliability of the circuit. To solve the above problems, there are also cases where a sealing ring is provided between the metal cover and the housing. However, the cover of the UAV data transmission radio is usually directly covered on the outside of the housing, and the housing does not have a corresponding groove for installing the sealing ring. Most of the existing sealing rings are of an annular structure and cannot be adaptively arranged along the circumference of the housing according to different sizes of the housing, resulting in the phenomenon that the sealing ring is not easy to install on the rectangular housing, and ultimately the problem of the sealing performance between the metal cover and the housing cannot be improved. Content of the Utility Model

[0004] To solve the technical problems existing in the above background technique, the utility model provides an unmanned aerial vehicle (UAV) data transmission radio with a waterproof structure.

[0005] The technical solution of the utility model is as follows:

[0006] An unmanned aerial vehicle (UAV) data transmission radio with a waterproof structure includes a housing and covers detachably arranged on its opposite sides. Both opposite sides of the housing are mounting surfaces, and an installation groove is formed along the circumference on the inner side of the mounting surface. The covers are arranged in the installation groove.

[0007] The installation groove includes a bottom surface and a side surface. A plurality of sealing strips are arranged along the circumference on the bottom surface. The plurality of sealing strips are located between the housing and the corresponding covers. The ends of adjacent sealing strips are connected by a flexible connecting piece, and the plurality of sealing strips are connected in a closed loop.

[0008] The thickness and width of the sealing strip are both smaller than the depth of the installation groove.

[0009] A multi-segment sealing strip is arranged around the bottom surface of the mounting groove on one side of the shell, and is located between the shell and the cover plate. By tightening the cover plate to the mounting groove of the shell, the multi-segment sealing strip is squeezed to form a sealed cavity inside the shell. Compared with the prior art in which the shell and the cover plate are only in close contact through metal surfaces, the sealing strip can better seal the shell and the cover plate to prevent water or water vapor from entering the shell and affecting the normal operation of the drone data transmission platform; and the multi-segment sealing strip can be cut to a certain length according to the size of different shells, and the segmented sealing strips are connected by flexible connectors, so that the multi-segment sealing strip can be suitable for the sealing of most shells and cover plates.

[0010] In order to increase the contact area between the sealing strip and the shell and the cover plate, the specific structure of the sealing strip is that a single sealing strip includes a first plane and a second plane arranged opposite to each other, the first plane is arranged close to the bottom surface, and the second plane can contact the corresponding cover plate.

[0011] In order to facilitate the installation of the multi-segment sealing strip in the installation groove and prevent the multi-segment sealing strip from detaching from the bottom surface of the installation groove during installation, thereby affecting the compression of the cover plate, a stop strip is further arranged along the circumference of the bottom surface. The stop strip is located on the inner side of the multi-segment sealing strip. The width of the sealing strip is along the direction from the first plane to the second plane. The ratio of the length of the stop strip along the depth direction of the installation groove to the width of the sealing strip is 0.5-0.7, so that the stop strip can be installed between the stop strip and the side of the installation groove without interfering with the deformation of the sealing strip caused by the cover plate being pressed.

[0012] The installation position of the above-mentioned sealing strip and the stop strip is that the sealing strip has a thickness direction along a direction perpendicular to its width, and the ratio of the vertical spacing between the stop strip and its adjacent side surface to the thickness of the sealing strip is 0.9-0.95, so that when the sealing strip is installed between the stop strip and the side surface, it can be snapped into the installation groove and will not be separated from the side surface of the installation groove and between the stop strip, which makes it convenient for the cover plate to tighten the sealing strip and achieve a sealed connection with the shell.

[0013] The structure of the above-mentioned sealing strip also includes that the sealing strip also includes a third plane located above the first plane and the second plane, and the third plane is arranged close to the side. The arrangement of the third plane can increase the contact area between the side of the sealing strip close to the side and the side, and cooperate with the first plane and the second plane to improve the sealing inside the shell.

[0014] In order to facilitate the tight connection between the flexible connector and the sealing strip, and to be able to cooperate with the sealing strip to achieve sealing between the shell and the cover under the tight pressure of the cover, the flexible connector is an elastic flexible sleeve, and the inner diameter of the flexible sleeve is smaller than the length or width of the sealing strip.

[0015] Regarding the specific structure of the flexible connector, the flexible connector includes a first pipe section, an intermediate connecting pipe section, and a second pipe section that are integrally formed and arranged along the length direction. The end portions of two adjacent sealing strips are respectively inserted into the first pipe section and the second pipe section.

[0016] To facilitate holding the flexible connector, the end portions of two adjacent sealing strips are respectively inserted into the first pipe section and the second pipe section, and the intermediate connecting pipe section is filled with a rubber layer. Compared with a hose with an empty interior, the filling of the rubber layer facilitates inserting one end of the sealing strip into the flexible connector respectively. To avoid affecting the pressing of the cover plate on multiple sealing strips, the elasticity of the rubber layer is set to be less than that of the sealing strip.

[0017] The beneficial effects of the present utility model are as follows:

[0018] Multiple sealing strips are arranged around the bottom surface of the installation groove on one side of the housing. When the cover plate is tightened in the installation groove of the housing through a threaded connector, the multiple sealing strips can be pressed against the housing. Compared with the connection method only through the metal surface between the housing and the cover plate, the connection through the sealing strip can greatly improve the sealing performance inside the housing;

[0019] In the prior art, the cover plate is directly connected to the outside of the housing through a threaded connector, so that the connection between the housing and the cover plate is directly exposed on the outside. This connection method makes the connection between the housing and the cover plate prone to ingress of water or water vapor. Especially when the UAV data transmission radio station works in an environment with high humidity, the present utility model arranges the cover plate in the installation groove inside the housing, so that the connection between the housing and the cover plate is not directly exposed on the outside of the housing, and the housing can also play a protective role, and it is also convenient to install the sealing strip, increasing the contact area between the sealing strip and the housing, thereby improving the sealing performance inside the housing;

[0020] To facilitate the installation of multiple sealing strips in the installation groove and prevent the multiple sealing strips from detaching from the bottom surface of the installation groove during installation, which affects the pressing of the cover plate, a retaining strip is also provided along the circumference of the bottom surface. The retaining strip is located inside the multiple sealing strips. The retaining strip can install the sealing strip between the retaining strip and the side surface of the installation groove without interfering with the deformation of the sealing strip when it is pressed tight by the cover plate;

[0021] To facilitate holding the flexible connector, the end portions of two adjacent sealing strips are respectively inserted into the first pipe section and the second pipe section, and the intermediate connecting pipe section is filled with a rubber layer. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0034] Refer to Figure 1 , Figure 2 and Figure 3 As shown, a data transmission radio for an unmanned aerial vehicle with a waterproof structure includes a housing 1 and cover plates 2 detachably arranged on opposite sides thereof. Both opposite sides of the housing 1 are mounting surfaces 11. An installation groove 12 is formed along the circumference of the inner side of the mounting surface 11, and the cover plate 2 is arranged in the installation groove 12. The installation groove 12 includes a bottom surface 121 and a side surface 122. A plurality of sealing strips 3 are arranged along the circumference of the bottom surface 121. The plurality of sealing strips 3 are located between the housing 1 and the corresponding cover plate 2. The ends of adjacent sealing strips 3 are connected by a flexible connecting piece 5, and the plurality of sealing strips 3 are arranged in a closed-loop connection. The plurality of sealing strips 3 are formed by connecting the ends of multiple sealing strips 3. The length of the sealing strip 3 is selected according to the size of the housing 1 and can be used for sealing housings 1 of different sizes.

[0035] The effect of arranging the cover plate 2 in the installation groove 12 inside the housing 1 in the present utility model is as follows: In the prior art, the cover plate 2 is directly connected to the outside of the housing 1 through a threaded connector 6, so that the connection between the housing 1 and the cover plate 2 is directly exposed on the outside. This connection method makes it easy for water or water vapor to enter the connection between the housing 1 and the cover plate 2, especially when the drone data transmission radio is working in an environment with high humidity. However, in the present utility model, the connection between the housing 1 and the cover plate 2 is not directly exposed on the outside of the housing 1, and the housing 1 can also play a protective role, and it is also convenient to install the sealing strip 3, improving the contact area between the sealing strip 3 and the housing 1, thereby improving the sealing performance inside the housing 1.

[0036] See Figure 4 、 Figure 5 and Figure 6 As shown, the thickness and width of the above-mentioned sealing strip 3 are both smaller than the depth of the installation groove 12. To increase the contact area between the sealing strip 3 and the housing 1 and the cover plate 2, the specific structure of the above-mentioned sealing strip 3 is that a single sealing strip 3 includes a first plane 31 and a second plane 32 arranged opposite to each other. The first plane 31 is closely attached to the bottom surface 121, and the second plane 32 can abut against the corresponding cover plate 2. The above-mentioned sealing strip 3 further includes a third plane 33 located above the first plane 31 and the second plane 32. The third plane 33 is close to the side surface 122. Arranging the third plane 33 can increase the contact area between one side of the sealing strip 3 close to the side surface 122 and the side surface 122, and cooperate with the first plane 31 and the second plane 32 to improve the sealing performance inside the housing 1.

[0037] See Figure 3 and Figure 9 As shown, to facilitate the installation of multiple sections of the sealing strip 3 in the installation groove 12 and prevent the multiple sections of the sealing strip 3 from detaching from the bottom surface 121 of the installation groove 12 during installation, which affects the pressing of the cover plate 2, a retaining strip 4 is also provided along the bottom surface 121 around its circumference. The retaining strip 4 is located inside the multiple sections of the sealing strip 3. The width direction of the sealing strip 3 is from the first plane 31 to the second plane 32. The ratio of the length of the retaining strip 4 in the depth direction of the installation groove 12 to the width of the sealing strip 3 is 0.5 - 0.7, so that the retaining strip 4 can install the sealing strip 3 between the retaining strip 4 and the side surface 122 of the installation groove 12 without interfering with the deformation of the sealing strip 3 when it is tightened by the cover plate 2.

[0038] The installation position of the above-mentioned sealing strip 3 and the retaining strip 4 is that the thickness direction of the sealing strip 3 is along the direction perpendicular to its width. The ratio of the vertical distance between the retaining strip 4 and the nearest side surface 122 to the thickness of the sealing strip 3 is 0.9 - 0.95. When the sealing strip 3 is installed between the retaining strip 4 and the side surface 122, it can be clamped in the installation groove 12 and will not detach from between the side surface 122 and the retaining strip 4 of the installation groove 12, which is convenient for the cover plate 2 to tightly press the sealing strip 3 and achieve a sealed connection with the housing 1.

[0039] See Figure 3 、 Figure 7 and Figure 8 As shown, to facilitate the tight connection between the flexible connector 5 and the sealing strip 3 and to enable the sealing of the housing 1 and the cover plate 2 in cooperation with the sealing strip 3 under the pressing of the cover plate 2, the flexible connector 5 is an elastic soft connecting sleeve, and the inner diameter of the soft connecting sleeve is smaller than the length or width of the sealing strip 3.

[0040] See Figure 7 and Figure 8 As shown, the specific structure of the flexible connector 5 is that the flexible connector 5 includes a first pipe section 51, an intermediate connecting pipe section 52, and a second pipe section 53 that are integrally formed and arranged along the length direction. The end portions of two adjacent sealing strips 3 are respectively inserted into the first pipe section 51 and the second pipe section 53. To facilitate holding the flexible connector 5, the end portions of two adjacent sealing strips 3 are respectively inserted into the first pipe section 51 and the second pipe section 53, and a rubber layer 54 is filled in the intermediate connecting pipe section 52. Compared with a hose with an empty interior, the filling of the rubber layer 54 facilitates inserting one end of the sealing strip 3 into the flexible connector 5 respectively. To avoid affecting the pressing of the cover plate 2 on multiple sections of the sealing strip 3, the elasticity of the rubber layer 54 is set to be smaller than that of the sealing strip 3.
