[0003] Due to the complex internal structure of the transceiver, shock absorption is needed to reduce the impact of external forces on the transceiver. Existing shock absorption methods generally involve covering the transceiver with shock-absorbing materials. However, since the transceiver generates a lot of heat during operation, this affects the heat dissipation of the transceiver. Summary of the Invention

The first, second, and third vibration damping assemblies have the same structure and respectively include a flexible tube, a core rod, a double-ended telescopic rod, a fixing rod, and a support rod. One side of the outer wall of the flexible tube is fixedly connected to the inner wall of the outer shell, and the other side of the outer wall of the flexible tube is fixedly connected to the outer wall of the inner shell. A core rod is provided inside the flexible tube, and one end of the fixing rod is fixedly connected to both sides of the core rod. The other end of the fixing rod is fixedly connected to the middle of the double-ended telescopic rod, and the two ends of the double-ended telescopic rod are fixedly connected to the support rod, which is fixedly connected to the inner wall of the flexible tube.

[0006] As a preferred embodiment of the shock absorption device for the Ku-band microwave transceiver described in this invention, the flexible tube is made of an elastic material.

[0007] As a preferred embodiment of the vibration damping device for the Ku-band microwave transceiver described in this invention, the gap between the outer wall of the inner shell and the inner wall of the outer shell is filled with coolant.

[0008] As a preferred embodiment of the vibration damping device for the Ku-band microwave transceiver described in this invention, a rib is provided between the two support rods, with the two ends of the rib fixedly connected to the support rods, and the rib slidably connected to the inner wall of the flexible hose.

[0009] As a preferred embodiment of the Ku-band microwave transceiver vibration damping device of the present invention, the double-headed telescopic rod includes a fixed cylinder, a piston head, and a movable rod. The fixed cylinder is fixedly connected to the middle of the fixed rod, and the piston head is slidably connected to the inner wall of the fixed cylinder. There are two piston heads, and the two piston heads are respectively connected to one end of the movable rod. The other end of the movable rod is fixedly connected to the support rod.

[0010] As a preferred embodiment of the Ku-band microwave transceiver vibration damping device of the present invention, the core rod and the fixing rod on the first and second vibration damping components are hollow inside, and the inside of the core rod is connected to the inside of the fixing cylinder through the fixing rod.

[0012] As a preferred embodiment of the vibration damping device for the Ku-band microwave transceiver described in this invention, one end of the core rod on the first and second vibration damping components is fixedly connected to the inner wall of the outer shell, and the other end of the core rod on the first and second vibration damping components passes through the outer shell and is fixedly connected to the main pipe, with one end of the main pipe connected to the air inlet pipe.

[0014] The beneficial effects of the present invention are as follows: By filling the gap between the outer wall of the inner shell and the inner wall of the outer shell with coolant, the present invention can cool the inner shell and the Ku-band microwave transceiver inside, which is beneficial to improving the heat dissipation capacity of the Ku-band micro transceiver. At the same time, the coolant can be used for liquid buffering to reduce shock.

[0015] When the outer casing is subjected to an external force on its left side, the outer casing moves to the right, while the inner casing remains in its original position due to inertia. At this time, the flexible tube on the left side of the outer casing is stretched, and the flexible tube itself absorbs some of the vibration. Moreover, the flexible tube will squeeze the double-headed telescopic rod through the support rod, and the gas inside the double-headed telescopic rod will be compressed, which will further play a role in shock absorption. This will help improve the shock absorption effect and prevent the inner casing and the Ku-band microwave transceiver inside from being affected by vibration. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0026] Reference Figures 1 to 5 This embodiment provides a Ku-band microwave transceiver vibration damping device, including a housing assembly 1 and a vibration damping assembly 2. The housing assembly 1 includes an outer shell 11 and an inner shell 12. The inner shell 12 is located inside the outer shell 11, and a gap is left between the outer wall of the inner shell 12 and the inner wall of the outer shell 11. In this preferred embodiment, the Ku-band microwave transceiver is installed inside the inner housing 12. The Ku-band microwave transceiver performs functions such as frequency conversion and transmission of signals. It adopts a time-division / simultaneous operation mode. When the receiving channel is working, the RF signal is down-converted to a certain frequency and sent to the intermediate frequency transceiver for signal processing. When the transmitting channel is working, the intermediate frequency signal is up-converted and amplified before being sent to the antenna for transmission.

[0027] The shock absorption assembly 2 includes a first shock absorption assembly 21, a second shock absorption assembly 22 and a third shock absorption assembly 23. The first shock absorption assembly 21 is located between the bottom wall of the outer shell 11 and the lower surface of the inner shell 12, the second shock absorption assembly 22 is located between the top wall of the outer shell 11 and the upper surface of the inner shell 12, and the third shock absorption assembly 23 is located between the inner side wall of the outer shell 11 and the outer side wall of the inner shell 12.

[0028] In this embodiment, the preferred shock-absorbing component 2 is used to absorb vibration. The first shock-absorbing component 21 can absorb vibration at the bottom of the inner shell 12, the second shock-absorbing component 22 can absorb vibration at the top of the inner shell 12, and the third shock-absorbing component 23 can absorb vibration around the sides of the inner shell 12, thus isolating the vibration of the outer shell 11 and the inner shell 12.

[0029] The first damping component 21, the second damping component 22, and the third damping component 23 have the same structure and each includes a hose 211, a core rod 212, a double-headed telescopic rod 213, a fixing rod 214, and a support rod 215. The outer wall of one side of the hose 211 is fixedly connected to the inner wall of the outer shell 11, and the outer wall of the other side of the hose 211 is fixedly connected to the outer wall of the inner shell 12. The core rod 212 is provided inside the hose 211. One end of the fixing rod 214 is fixedly connected to both sides of the core rod 212. The other end of the fixing rod 214 is fixedly connected to the middle of the double-headed telescopic rod 213. The two ends of the double-headed telescopic rod 213 are fixedly connected to the support rod 215. The support rod 215 is fixedly connected to the inner wall of the hose 211.

[0030] In this preferred embodiment, coolant is filled in the gap between the outer wall of the inner housing 12 and the inner wall of the outer housing 11. The coolant cools the inner housing 12 and the Ku-band microwave transceiver inside, improving the heat dissipation capacity of the Ku-band transceiver. Simultaneously, the coolant acts as a liquid buffer, reducing vibration. The flexible hose 211 holds the inner housing 12 in place vertically and around its perimeter. When the left side of the outer housing 11 is subjected to external force, it moves to the right, while the inner housing 12 remains in its original position due to inertia. At this time, the flexible hose 211 on the left side of the outer housing 11 is stretched, absorbing some vibration. Furthermore, the hose 211 compresses the double-ended telescopic rod 213 via the support rod 215, compressing the gas inside the double-ended telescopic rod 213, further reducing vibration and improving the overall shock absorption effect, thus preventing vibration from affecting the inner housing 12 and the Ku-band microwave transceiver inside. Example 2

[0031] Reference Figures 1 to 8 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

[0032] Reference Figure 5 The hose 211 is made of an elastic material.

[0033] In this embodiment, the flexible hose 211 is preferably made of rubber material, which is elastic and can be stretched laterally. The flexible hose 211 connects the outer wall of the inner shell 12 and the inner wall of the outer shell 11. The flexible connection helps to block vibration transmission and improve the shock absorption effect.

[0034] The gap between the outer wall of the inner shell 12 and the inner wall of the outer shell 11 is filled with coolant.

[0035] In this preferred embodiment, the coolant can cool the inner housing 12 and the internal Ku-band microwave transceiver, which helps to improve the heat dissipation capacity of the Ku-band micro transceiver. At the same time, the coolant can be used for liquid buffering to reduce shock.

[0036] A rib 216 is provided between the two support rods 215. The two ends of the rib 216 are fixedly connected to the support rods 215 respectively, and the rib 216 is slidably connected to the inner wall of the hose 211.

[0037] In this preferred embodiment, multiple ribs 216 are provided, which helps to support the inner wall of the hose 211.

[0038] Reference Figure 6The double-headed telescopic rod 213 includes a fixed cylinder 2131, a piston head 2132, and a movable rod 2133. The fixed rod 214 is fixedly connected to the middle of the fixed cylinder 2131, and the piston head 2132 is slidably connected to the inner wall of the fixed cylinder 2131. There are two piston heads 2132, and the two piston heads 2132 are respectively connected to one end of the movable rod 2133. The other end of the movable rod 2133 is fixedly connected to the support rod 215.

[0039] In this preferred embodiment, when the left side of the outer shell 11 is subjected to an external force, the outer shell 11 moves to the right, while the inner shell 12 remains in its original position due to inertia. At this time, the flexible tube 211 on the left side of the outer shell 11 is stretched. The flexible tube 211 itself absorbs some of the vibration, and the flexible tube 211 will squeeze the movable rod 2133 through the support rod 215. The movable rod 2133 drives the piston head 2132 to move, squeezing the gas between the two piston heads 2132, which further plays a role in shock absorption. This helps to improve the shock absorption effect and prevent the inner shell 12 and the internal Ku-band microwave transceiver from being affected by vibration. When the external force is removed, the gas between the two piston heads 2132 can reset the support rod 215 and restore the flexible tube 211 to its original shape.

[0040] Reference Figure 4 and Figure 7 The core rod 212 and the fixing rod 214 on the first shock absorber 21 and the second shock absorber 22 are hollow inside, and the inside of the core rod 212 is connected to the inside of the fixing cylinder 2131 through the fixing rod 214.

[0041] Preferably, in this embodiment, the gas inside the core rod 212 of the first damping component 21 and the second damping component 22 can enter the fixed cylinder 2131 through the fixed rod 214. When gas is pumped into the core rod 212 of the first damping component 21 and the second damping component 22, the gas pushes the two piston heads 2132 away from each other, and the piston heads 2132 drive the movable rod 2133 to move, thus extending the entire double-headed telescopic rod 213. When gas is extracted from the core rod 212 of the first damping component 21 and the second damping component 22, the gas pressure causes the two piston heads 2132 to move closer to each other, and the piston heads 2132 drive the movable rod 2133 to move, thus retracting the entire double-headed telescopic rod 213.

[0042] Reference Figure 4 The two ends of the core rod 212 on the third shock absorber 23 are respectively fixedly connected to the inner wall of the outer shell 11.

[0043] In this preferred embodiment, the position of the core rod 212 can be fixed to prevent the parts inside the hose 211 from becoming scattered.

[0044] One end of the core rod 212 on the first shock absorber 21 and the second shock absorber 22 is fixedly connected to the inner wall of the outer shell 11, and the other end of the core rod 212 on the first shock absorber 21 and the second shock absorber 22 passes through the outer shell 11 and is fixedly connected to the main pipe 2121. One end of the main pipe 2121 is connected to the air intake pipe 2122.

[0045] Preferably, in this embodiment, the air inlet pipe 2122 is connected to an existing suction air pump. The suction air pump can pump or extract gas into or from the main pipe 2121 through the air inlet pipe 2122. When gas is pumped into the core rod 212 on the first damping component 21 and the second damping component 22, the gas pushes the two piston heads 2132 away from each other. The piston heads 2132 drive the movable rod 2133 to move, and the entire double-headed telescopic rod 213 extends. The head telescopic rod 213 pushes the hose 211 to move. At this time, the radial dimension of the hose 211 increases, and more coolant enters the hose 211. There are multiple hoses 211 arranged side by side. At this time, the coolant between two adjacent hoses 211 is squeezed out, which is beneficial to drive the flow of coolant in the gap between the outer shell 11 and the inner shell 12, and is beneficial to improve the heat dissipation effect.

[0046] The suction pump repeatedly pumps and extracts gas into and from the main pipe 2121 through the intake pipe 2122. At this time, the double-headed telescopic rod 213 repeatedly extends and retracts, and the radial dimension of the hose 311 increases and decreases, which helps to accelerate the flow of coolant in the gap between the outer shell 11 and the inner shell 12 and improve the heat dissipation effect.

[0047] Reference Figure 1 The outer shell 11 is fixedly connected to the fixing pipe 111, and the fixing pipe 111 is threadedly connected to the sealing cover 112.

[0048] In this preferred embodiment, opening the sealing cover 112 allows coolant to be added into the gap between the outer shell 11 and the inner shell 12, and tightening the sealing cover 112 onto the fixing tube 111 seals the fixing tube 111.
