[0002] The base station RF power amplifier module is a core component of a radio transmission system. Its main function is to amplify weak RF signals to sufficient power to achieve long-distance transmission or strong interference effects. In drone countermeasures equipment, the performance of the RF power amplifier module directly affects the countermeasure effect, including interference distance, frequency band coverage, and energy efficiency. The RF power amplifier module is essentially an energy converter, and its working principle is based on the transistor effect. By applying a bias voltage, the transistor operates in the amplification region, converting the weak energy of the input RF signal into high-power output.

[0003] Conventional transmission interface structures, due to their open design, are susceptible to damage from external factors when not in use, thus affecting the overall lifespan of the transmission interface structure and resulting in deficiencies in overall efficiency and practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a base station radio frequency power amplifier module signal transmission interface structure, including an outer frame assembly and a protective cover assembly. A transmission interface assembly is installed in the middle of the inner side of the outer frame assembly. The protective cover assembly is disposed on the front side facade of the transmission interface assembly, and an adjustment bracket is installed between the protective cover assembly and the outer frame assembly. The protective cover assembly includes a shock-absorbing cover, a docking pin, a buffer pad, a docking groove, and a handle. Transmission interface assemblies are horizontally placed at the four opposite corners of the side of the shock-absorbing cover near the transmission interface assembly. A buffer pad is installed in the middle of the side of the shock-absorbing cover near the transmission interface assembly. A docking groove is opened on the surface of the shock-absorbing cover away from the transmission interface assembly. Handles are symmetrically installed on the left and right sides of the surface of the shock-absorbing cover away from the transmission interface assembly.

[0006] Furthermore, the outer frame assembly includes a crash barrier, a support frame, a mating seat, a fixing corner plate, and a sealing ring. The crash barrier has a support frame in the middle, and mating seats are provided at the four opposite corners of the support frame. The crash barrier has a fixing corner plate on its side, and a sealing ring is installed on the edge of the crash barrier away from the protective cover assembly.

[0007] Furthermore, the anti-collision frame and the support frame are fixedly connected, and the docking seat and the support frame are an integral structure.

[0008] Furthermore, the docking seat has a hole structure in the middle that matches the outer surface structure of the docking pile, and the shock-absorbing cover and the docking pile are integrated into one structure.

[0009] Furthermore, the fixed corner plate is welded to the anti-collision frame, and the sealing ring is installed on one side edge of the anti-collision frame with an embedded structure. The fixed corner plates are symmetrically arranged on the left and right ends of the upper and lower sides of the anti-collision frame, as well as on the upper and lower ends of the left and right sides.

[0010] Furthermore, the buffer pad is installed on one side surface of the shock-absorbing cover using an embedded structure, and the shock-absorbing cover and the handle are fixedly connected.

[0011] Furthermore, the adjustment frame includes a fixed base, a first double-segment hinge, a damping telescopic rod, a second double-segment hinge, and a connecting seat. The first double-segment hinge is installed on one side of the fixed base, and the damping telescopic rod is installed at the end of the first double-segment hinge away from the fixed base. The second double-segment hinge is connected to the end of the damping telescopic rod away from the damping telescopic rod, and the connecting seat is installed at the end of the second double-segment hinge away from the damping telescopic rod.

[0012] Furthermore, the end of the fixed seat away from the first double-segment hinge is movably mounted on the top surface of the fixed seat, and the side of the connecting seat away from the second double-segment hinge is movably mounted inside the docking groove.

[0013] This utility model provides a signal transmission interface structure for a base station radio frequency power amplifier module, which has the following features:

[0014] Beneficial effects:

[0015] 1. This utility model features a protective cover assembly on the front of the transmission interface component. A docking seat is located at each of the four opposite corners of the support frame, and a docking pin is provided on one side of the shock-absorbing cover. This allows the protective cover assembly to be horizontally inserted into the front facade of the outer frame component via the docking pin and the docking seat, providing excellent structural protection for the transmission interface component. The shock-absorbing cover, combined with the anti-collision frame, provides excellent structural protection for the transmission interface component, preventing damage from external factors when not in use. The buffer pad effectively absorbs shocks from the various transmission interfaces of different specifications on the surface of the transmission interface component, while also ensuring convenient assembly and disassembly. The fixed corner plates on the edge of the anti-collision frame maximize the structural stability and robustness of the entire device.

[0016] 2. This utility model features an adjustment frame between the outer frame assembly and the protective cover assembly. One end of the adjustment frame is mounted on the top of the anti-collision frame, and the other end is installed inside the docking groove via a connecting seat. This allows the outer frame assembly and the protective cover assembly to be connected and combined. The first and second double-segment hinges allow the adjustment frame to be adjusted vertically within a certain angle range. This enables the protective cover assembly connected to the adjustment frame to be opened during use, avoiding unnecessary structural interference with the transmission interface assembly. The extensibility of the damping telescopic rod ensures sufficient structural mobility and ductility for the adjustment frame, preventing unnecessary structural interference during maintenance. Furthermore, the adjustment frame ensures good structural connection between the outer frame assembly and the protective cover assembly, preventing unnecessary structural detachment and guaranteeing ease of use and stability.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 5 As shown, a base station RF power amplifier module signal transmission interface structure includes an outer frame assembly 1 and a protective cover assembly 3. A transmission interface assembly 2 is installed in the middle of the outer frame assembly 1. The protective cover assembly 3 is located on the front facade of the transmission interface assembly 2, and an adjustment bracket 4 is installed between the protective cover assembly 3 and the outer frame assembly 1. The protective cover assembly 3 includes a shock-absorbing cover 301, a mating stud 302, a buffer pad 303, a mating groove 304, and a handle 305. The shock-absorbing cover 301 has horizontally spaced features at four opposite corners on the side closest to the transmission interface assembly 2. The outer frame assembly 1 includes a transmission interface component 2, and a shock-absorbing cover 301 with a buffer pad 303 installed in the middle of the side closest to the transmission interface component 2. A mating groove 304 is formed on the surface of the shock-absorbing cover 301 away from the transmission interface component 2, and handles 305 are symmetrically installed on the left and right sides of the surface of the shock-absorbing cover 301 away from the transmission interface component 2. The outer frame assembly 1 includes a crash barrier 101, a support frame 102, a mating seat 103, a fixing angle plate 104, and a sealing ring 105. The support frame 102 is located in the middle of the crash barrier 101. A docking seat 103 is provided at each of the four opposite corners of the 102, and a fixing corner plate 104 is provided on the side of the anti-collision frame 101. A sealing ring 105 is installed on the edge of the anti-collision frame 101 away from the protective cover assembly 3. The anti-collision frame 101 and the support frame 102 are fixedly connected, and the docking seat 103 and the support frame 102 are integrally formed. The docking seat 103 has a socket structure in the middle that matches the outer surface structure of the docking stake 302. The shock-absorbing cover 301 and the docking stake 302 are integrally formed. The fixed angle plate 104 is welded to the anti-collision frame 101, and the sealing ring 105 is installed on one side edge of the anti-collision frame 101 with an embedded structure. The fixed angle plates 104 are symmetrically arranged on the left and right ends of the upper and lower sides of the anti-collision frame 101, as well as the upper and lower ends of the left and right sides. This allows the protective cover assembly 3 to be quickly inserted into the front side of the outer frame assembly 1 by using the horizontal insertion between the docking pin 302 and the docking seat 103, thereby providing good structural shielding for the transmission interface assembly 2.

[0025] like Figures 1 to 5As shown, the buffer pad 303 is embedded in one side surface of the shock absorber cover 301, and the shock absorber cover 301 and the handle 305 are fixedly connected. The adjustment frame 4 includes a fixed base 401, a first double-segment hinge 402, a damping telescopic rod 403, a second double-segment hinge 404, and a connecting seat 405. The first double-segment hinge 402 is installed on one side of the fixed base 401, and the damping telescopic rod 403 is installed at the end of the first double-segment hinge 402 away from the fixed base 401. The second double-segment hinge 404 is connected to the end of the damping telescopic rod 403 away from the damping telescopic rod 403. 04. A connecting seat 405 is installed at one end away from the damping telescopic rod 403. The end of the fixed seat 401 away from the first double-segment hinge 402 is movably installed on the top surface of the fixed seat 401. The side of the connecting seat 405 away from the second double-segment hinge 404 is movably installed inside the docking groove 304. Under the structural movement of the first double-segment hinge 402 and the second double-segment hinge 404, the entire adjusting frame 4 can be adjusted vertically by flipping up and down within a certain angle range. This allows the protective cover assembly 3 connected to the adjusting frame 4 to open its structure when in use.

[0026] In summary, as Figures 1 to 5 As shown, the base station RF power amplifier module signal transmission interface structure is used by first fixing the entire device structure to the equipment mounting structure surface using the fixing corner plates 104 on the four sides of the anti-collision frame 101 and bolts. The sealing ring 105 on one side of the anti-collision frame 101 can ensure the sealing between the entire device and the mounting structure surface, and at the same time ensure the stability after fixing.

[0027] When the transmission interface component 2 inside the outer frame component 1 needs to be used, the first double-segment hinge 402 on one side of the fixed seat 401 and the second double-segment hinge 404 at one end of the damping telescopic rod 403 are used to rotate the structure. At the same time, the handle 305 installed on the outer surface of the shock-absorbing cover 301 can be used to pull the entire protective cover component 3 out from the docking seat 103 at the four opposite corners of the support frame 102 using the docking pins 302 on one side of the shock-absorbing cover 301. Then, the structure is folded vertically to expose the structure of the transmission interface component 2, so that the user can use the various specifications of transmission interfaces installed on the surface of the transmission interface component 2.

Many modifications and variations will be apparent to those skilled in the art.
