Description

Technical Field

[0001] The invention relates to the technical field of telemetry radio stations, in particular to a protective structure for telemetry radio stations which is anti-covering. Background Art

[0002] Anti-coverage telemetry radios are often used in drones, and can be used with drones to achieve many precise tasks such as environmental monitoring and data collection;

[0003] The radio station is usually built into a carrier. Since the transmitter and receiver inside the radio station generally need to be installed with high precision, in order to ensure accurate data collection, vibration and impact that change the relative position of the transmitter and receiver should be avoided as much as possible during the operation of the radio station. Therefore, the radio station usually needs to be connected to the carrier through a protective structure to achieve shock absorption and stability of the connection.

[0004] See also Figure 1 ; Existing protective structures usually use elastic components and sliding components to stabilize the radio station in the carrier; however, the sliding pair in the sliding component usually cooperates with the track gap. The existence of the gap will cause the remote sensing radio station to collide with the carrier. At the same time, since the connection method of the sliding pair is specific, this will also cause, when the ambient temperature changes significantly, due to the elastic deformation of the sliding pair, the clamping force between the sliding pair and the track becomes larger, thereby increasing the friction force, exceeding the design value, which will cause the sensitivity of the elastic component to decrease and the shock absorption function will be seriously weakened.

[0005] Based on this, the present invention designs an anti-covering protection structure for telemetry radio stations to solve the above problems. Summary of the invention

[0035] See also Figure 1-13 The present invention provides a technical solution: a protective structure for a telemetry radio station with an anti-covering function, comprising a mounting shell 1, a frame plate 2 is arranged inside the mounting shell 1, a cover plate 3 is arranged directly above the frame plate 2, corresponding bolt holes 12 are opened above the frame plate 2 and the cover plate 3, and restriction groups are arranged on both the left and right sides of the frame plate 2;

[0036] The limiting group includes a vertical plate 4 and an auxiliary spring 13, the auxiliary spring 13 is fixedly connected between the inner wall of the mounting shell 1 and the bottom of the frame plate 2, a slot 5 is opened on the vertical plate 4, the end of the frame plate 2 is located inside the slot 5, the side wall of the vertical plate 4 is slidably connected with a driving member 6 in the vertical direction, and connecting members 7 are arranged on the left and right sides of the driving member 6, and the two connecting members 7 are provided with a first limit member 8 and a second limit member 9 near the top and the bottom. The two connecting members 7 are both slidably connected to the vertical plate 4 in the horizontal direction, and a first spring 29 is fixedly connected between the two connecting members 7 and the inner wall of the vertical plate 4, a pull rope 10 is fixedly connected between the two connecting members 7, and the middle part of the pull rope 10 is located below the driving member 6, and positioning members 11 are arranged on the left and right sides of the vertical plate 4 near the two first limit members 8 and the two second limit members 9, and the positioning members 11 are fixedly connected to the frame plate 2.

[0037] like Figure 1 , Figure 3-Figure 10 As shown:

[0038] Before the radio station is placed, the cover plate 3 and the frame plate 2 are in a separated state. At this time, the two sides of the frame plate 2 are in a tendency to move left and right and up and down inside the slot 5, and at this time, the two connecting members 7 are both on the left and right sides of the vertical plate 4. Then, the radio station is placed inside the frame plate 2, and the cover plate 3 is placed on the frame plate 2. After the cover plate 3 approaches the frame plate 2 to the position in contact with the top of the driving member 6, the cover plate 3 is pressed down. After the cover plate 3 is pressed down, the driving member 6 will slide down along the vertical plate 4, and at this time, the bottom end of the driving member 6 will press down the pull rope 10 so that the two ends of the pull rope 10 drive the two connecting members 7 to slide along the vertical plate 4. At this time, the first spring 29 will be elastically compressed, and the two connecting members 7 will drive the two first limiting members 8 and the two second limiting members 9 to move in the direction of the positioning member 11. After the driving member 6 drops to the maximum extent, the bolt hole 12 on the cover plate 3 will be aligned with the bolt hole 12 on the frame plate 2. At this time, the two first The limiting member 8 and the two second limiting members 9 will stop after moving to contact with the two positioning members 11. At this time, the cover plate 3 and the frame plate 2 can be fixed by bolts. At this time, the inner top wall of the cover plate 3 will contact with the top of the radio station to resist the radio station. At this time, the two positioning members 11 on the left and right sides will be restricted by the first limiting member 8 and the second limiting member 9, so that the freedom of movement of the positioning member 11 in the left and right directions inside the slot 5 disappears while the freedom of movement in the up and down directions is retained. Then, when the shaking generated during the subsequent flight of the aircraft and the shaking and vibration generated during the installation and disassembly process, the frame plate 2 slides up and down along the vertical plate 4 to be buffered by the auxiliary spring 13, and the deformation of the traditional sliding pair during temperature changes will not cause the interval between the track to become larger, thereby avoiding the active shaking generated between the sliding pair and the track, which causes the radio station and the carrier to be actively collided and the buffering of the elastic component is lost;

[0039] Moreover, when the radio station needs to be disassembled and repaired each time, each disassembly of the radio station in the traditional sliding method means that the sliding pair is reset, while in this method, after each placement of the radio station, the first limiter 8 and the second limiter 9 actively limit the positioning member 11 to ensure normal sliding effect, and the gap caused by temperature changes will not cause the specific sliding pair of the traditional method to be difficult to adapt to the track for a long time, resulting in the loss of buffer protection effect;

[0040] Furthermore, in the process of the driving member 6 pressing down the pull rope 10 to move the two connecting members 7 toward the positioning member 11, if the first limiting members 8 and the second limiting members 9 on both sides are at different distances from the positioning members 11 on both sides, then there will be a problem that the first limiting members 8 and the second limiting members 9 on both sides do not contact the positioning members 11 at the same time. However, the driving member 6 is in continuous contact with the pull rope 10 during the descent process. Therefore, even if the first limiting member 8 or the second limiting member 9 on one side contacts the positioning member 11 first, the pulling of the pull rope 10 during the descent process of the driving member 6 will cause the pull rope 10 to slide relative to the bottom end of the driving member 6 to overcome this phenomenon.

[0041] When the radio station needs to be taken out, the connection between the cover plate 3 and the frame plate 2 is released by bolts and the cover plate 3 is taken out. Then the drive member 6 and the pull rope 10 will automatically reset under the elastic reset action of the first spring 29, so that the two connecting members 7 can be away from the positioning member 11 to prepare for the protection work when the radio station is placed next time.

[0042] Auxiliary groups are set above the restricted groups;

[0043] The auxiliary group includes a cross bar 14, a force-bearing member 18 and a first roller 19 rotatably connected to the first limit member 8 and the second limit member 9. The cross bar 14 is located inside the vertical plate 4 and is slidably connected to the vertical plate 4 in the vertical direction. The cross bar 14 is slidably connected to the two first limit members 8 in the horizontal direction. The two first limit members 8 are both slidably connected to the connecting member 7 in the vertical direction. A second spring 15 is fixedly connected between the end of the connecting member 7 and the inner wall of the first limit member 8. The side wall of the cross bar 14 is rotatably connected to a support rod 16, and the support rod 16 is rotatably connected to a contact rod 17. The bottom end of the contact rod 17 is rotatably connected to the side wall of the vertical plate 4, and the force-bearing member 18 is rotatably connected to the inner wall of the cover plate 3.

[0044] like Figure 2 As shown:

[0045] When the carrier is an aircraft, due to the changeable flight posture of the aircraft, when the height of the shell of the radio becomes larger (there are many reasons for the increase in the shell height, such as the change in the shell size caused by the replacement of the radio and the possible thermal expansion and contraction causing the shell to become larger, such as Figure 2When the center of the housing changes, the center will be transferred to b) due to a), and its center of gravity will tend to rise. When the aircraft is tilted during flight missions, the radio will exert different pressures on the "wheels" (force-bearing wheels) at a fixed distance, which can easily cause deformation of the wheel bearing parts, thereby affecting the positioning accuracy.

[0046] When the cover plate 3 and the frame plate 2 are fixed by bolts, the contact rod 17 is located on one side of the force-bearing member 18 and fits with the contact rod 17. At this time, it can be assumed that the force-bearing member 18 and the radio housing of the same model are in contact after placement, but the force-bearing member 18 will not be lifted up. When the height of the shell increases, the radio housing will push the force-bearing member 18 to rotate at a larger angle. Then the force-bearing member 18 will rotate around the rotation axis after rotation, and will push the contact rod 17 to rotate around the rotation axis through the other end of the force-bearing member 18. When the contact rod 17 rotates, it will drive the cross bar 14 to slide up along the inside of the vertical plate 4 through the support rod 16. At this time, the two first limit members 8 will be driven to slide up along the connecting member 7 and the second spring 15 will be compressed. At this time, the two first limit members 8 and the first roller 19 will rise a corresponding distance, but at this time it still does not hinder the frame plate 2 and the positioning member 11 from sliding up and down. It just changes the distance between the first limit member 8 and the first roller 19 above it relative to the second limit member 9. Figure 2 The center of gravity of the housing shown in the figure will be transferred from a to b, thereby reducing the load on the first stopper 8 and the first roller 19 above it, so as to avoid deformation of the first roller 19 and the first stopper 8 due to the increase in the load, thereby limiting the accuracy of subsequent positioning;

[0047] The present invention utilizes the change in height of the shell to drive the force-bearing member 18 to a rotation angle, so that the first roller 19 and the first limit member 8 above can be controlled to move upward to reduce the load, thereby avoiding the influence of the first roller 19 and the first limit member 8 above when the aircraft is tilted, thereby avoiding the problem of limited subsequent positioning accuracy.

[0048] The side walls of the vertical plate 4 near the two connecting members 7 are fixedly connected with guide members 20 . A through hole is provided in the middle of the guide members 20 , and the pull rope 10 passes through the through holes on the two guide members 20 .

[0049] A second roller 21 is disposed above the pull rope 10 , and the second roller 21 is rotatably connected to the bottom end of the driving member 6 .

[0050] like Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown:

[0051] When the driving member 6 presses down the pull rope 10, the pull rope 10 will move in the through hole inside the guide member 20, and then the guide member 20 will guide the pull rope 10 during its movement. The second roller 21 will reduce the friction when the pull rope 10 is pressed down, so that the pull rope 10 can drive the second roller 21 to rotate through friction.

[0052] A U-shaped rod 22 is arranged below the driving member 6, and the U-shaped rod 22 is slidably connected to the side wall of the vertical plate 4 in the vertical direction. A third spring 23 is fixedly connected between the U-shaped rod 22 and the inner wall of the vertical plate 4. Two rack rods 24 are fixedly connected to the top of the U-shaped rod 22, and one-way gears 25 are arranged below the two rack rods 24. The two one-way gears 25 are respectively rotatably connected to the side walls of the two connecting members 7.

[0053] like Figure 4 and Fig.10 As shown:

[0054] When the driving member 6 presses the pull rope 10 to the limit, the cover plate 3 and the frame plate 2 are fixed by bolts to fix the pull rope 10 after being pressed down. When the driving member 6 presses the pull rope 10 to the limit, the driving member 6 will also press the U-shaped rod 22 to make the U-shaped rod 22 slide down along the vertical plate 4 to the limit. At this time, the third spring 23 will be compressed to the limit, and the one-way gears 25 on the left and right sides can only rotate clockwise and counterclockwise respectively. At this time, the rack rod 24 will follow the U-shaped rod 22 to the position meshing with the teeth of the one-way gear 25, so that the one-way gear 25 can actively position the connecting member 7 after the driving member 6 is dropped to the limit to prevent the possibility of the pull rope 10 loosening or breaking.

[0055] Positions corresponding to the first limiting member 8 , the second limiting member 9 and the positioning member 11 are all provided with positioning grooves 26 , and rollers 27 are rotatably connected inside the positioning grooves 26 .

[0056] like Figure 8 As shown:

[0057] The first limit member 8 and the second limit member 9 move toward the positioning member 11 through the positioning groove 26. At this time, the first limit member 8 will slide along the cross bar 14. When the roller 27 inside the positioning groove 26 contacts the positioning member 11, the left and right restriction of the positioning member 11 can be completed. The contact between the positioning member 11 and the roller 27 can reduce friction when the positioning member 11 vibrates and slides up and down and is buffered by the auxiliary spring 13.

[0058] The rotating shaft of the force bearing member 18 is sleeved with a torsion spring 28 .

[0059] like Figure 5 and Fig.13 As shown:

[0060] The torsion spring 28 on the force-bearing member 18 can limit the rotational freedom of the force-bearing member 18, so that the force-bearing member 18 will not rotate at will when not actively driven, which facilitates the stability of the position during installation and disassembly.

[0061] The cover plate 3 and the frame plate 2 can be made of aluminum, copper or other materials with good thermal conductivity.

[0062] As shown in the figure:

[0063] By setting the materials of the cover plate 3 and the frame plate 2, the heat dissipation effect can be increased.
