[0002] Radio frequency transceiver, RF for short, is radio frequency current, which is the abbreviation of a high-frequency alternating electromagnetic wave with excellent long-distance transmission capability; therefore, RF transceiver transmission is widely used in vehicle monitoring, aircraft navigation, data transmission and other fields.

[0003] In the related art, a radio frequency transceiver needs to be subjected to performance testing before being put into use to check whether the radio frequency transceiver is qualified.

[0004] Regarding the above-mentioned related technologies, when a performance test is performed on a radio frequency transceiver, the radio frequency transceiver to be tested is easily affected by external electromagnetic interference, which affects the accuracy of the test results, and thus needs to be improved. Summary of the Invention

[0005] In order to reduce external electromagnetic interference to a radio frequency transceiver, the present application provides an isolation device for a radio frequency transceiver.

[0006] The present application provides an isolation device for a radio frequency transceiver device using the following technical solutions:

[0007] An isolation device for a radio frequency transceiver comprises a carrying platform for carrying the radio frequency transceiver, an isolation cover for covering the radio frequency transceiver being provided on the carrying platform, a fixing frame being provided on the carrying platform, a driving member for driving the isolation cover away from or towards the carrying platform being provided on the fixing frame, and a closing assembly being provided on the carrying platform for closing a gap between the isolation cover and the carrying platform.

[0008] By adopting the above technical solution, the RF transceiver to be tested is placed on the carrier, the output end of the control driver is extended, the RF transceiver is covered with an isolation cover that isolates electromagnetic and signals, and then the gap between the isolation cover and the carrier is sealed with a sealing component, thereby reducing external electromagnetic interference to the RF transceiver and achieving isolation of the signals transmitted and received by the RF transceiver.

[0009] Preferably, the isolation cover includes an outer shell, an absorption layer and an inner shell, the outer shell is arranged at the output end of the driving member, the inner shell is arranged inside the outer shell, and the absorption layer is arranged between the outer shell and the inner shell to absorb electromagnetic radiation.

[0010] By adopting the above technical solution, the outer shell and the inner shell are matched with each other, and the double-layer signal isolation material is used to ensure the isolation effect of the isolation cover; in addition, the electromagnetic radiation is absorbed by the absorption layer, which further improves the isolation effect of the isolation cover.

[0011] Preferably, the closing assembly includes a plurality of sliding plates, a plurality of extension plates, a plurality of isolation strips, a mounting frame and a plurality of elastic members; all of the sliding plates are slidably arranged on the supporting platform, and all of the sliding plates are distributed around the isolation cover, the extension plates are arranged on the side walls of each group of sliding plates facing the supporting platform, the isolation strips are arranged on the side walls of the sliding plates and the extension plates to close the gap between the isolation cover and the supporting platform; the mounting frame is arranged on the supporting platform, and the elastic member is arranged between each group of sliding plates and the mounting frame to drive the sliding plate to abut the isolation cover through its own elastic force.

[0012] By adopting the above technical solution, when the driving member drives the isolation cover to abut against the supporting platform, the elastic member uses its own elastic force to drive the sliding plate to drive the isolation strip to abut against the side wall of the isolation cover. At the same time, the extension plate makes the isolation strip abut against the supporting platform, and the ends of adjacent isolation strips fit tightly, thereby achieving the closure of the gap between the isolation cover and the supporting platform.

[0013] Preferably, the closing assembly further comprises a guide rod and an adjusting nut; the guide rod is arranged on the side wall of each group of sliding plates facing the mounting frame, and the guide rod, elastic member and adjusting nut are respectively arranged in one-to-one correspondence, each of the guide rods passes through the corresponding elastic member, and each of the guide rods passes through the mounting frame; the adjusting nut is threadedly connected to the end of the corresponding guide rod away from the isolation cover, and the adjusting nut is against the side wall of the mounting frame.

[0014] By adopting the above technical solution, the guide rod limits the contraction path of the elastic part, reducing the skew phenomenon of the elastic part during the contraction process; the adjusting nut is threadedly connected to the guide rod to adjust the distance between the sliding plate and the fixed frame, thereby adjusting the initial compression amount of the elastic part, thereby ensuring that the elastic part has sufficient elastic force to drive the sliding plate to stably abut the isolation cover.

[0015] Preferably, the ends of adjacent isolation strips that are close to each other are provided with isolation plates, one end of each isolation strip in the longitudinal direction is provided with a magnetic part, and the other end of each isolation strip is provided with an adsorption part for magnetic attraction with the magnetic part, and all the magnetic parts and adsorption parts are distributed in sequence around the isolation cover.

[0016] By adopting the above technical solution, when the sliding plate drives the isolation strip to abut the isolation cover, the magnetic part and the adsorption part are magnetically attracted to each other, so that the isolation plates at the ends of adjacent isolation strips are stably fitted together, thereby achieving stable fitting of the ends of adjacent isolation strips, and further improving the effect of the isolation strip in sealing the gap between the isolation cover and the supporting platform.

[0017] Preferably, a positioning frame is provided on the carrying platform, and a lifting member is provided on the positioning frame. The output end of the lifting member is connected to the mounting frame for driving the mounting frame to approach or move away from the carrying platform.

[0018] By adopting the above technical solution, when the sliding plate does not drive the isolation strip to abut the isolation cover, the output end of the lifting member is in a retracted state, and the suspended mounting frame leaves a gap between the extension plate and the supporting platform, so that the sliding plate drives the isolation strip to abut the isolation cover. Then, the output end of the lifting member is controlled to extend, so that the mounting frame drives the sliding plate and the extension plate to gradually approach the supporting platform, so that the isolation strip on the extension plate is tightly fitted with the supporting platform, reducing the wear caused by the isolation strip on the extension plate always abutting against the supporting platform, and ensuring the service life of the isolation strip.

[0019] Preferably, the supporting platform is provided with a traction assembly for pulling all the sliding plates synchronously away from the isolation cover.

[0020] By adopting the above technical solution, the traction assembly pulls all the sliding plates away from the isolation cover synchronously, so that the driving member drives the isolation cover to quickly move away from the bearing platform, and facilitates the unloading of the tested RF transceiver.

[0021] Preferably, the traction assembly includes several groups of traction ropes, rotating disks and rotating motors; the traction ropes and sliding plates are respectively arranged in one-to-one correspondence, each of the traction ropes is arranged on the corresponding sliding plate, and the end of each traction rope away from the isolation cover passes through the mounting frame; a mounting cavity is provided inside the support platform, the rotating disk is rotatably provided inside the mounting cavity, and the rotating motor is provided on the support platform to drive the rotating disk to rotate; a makeshift channel for connecting to the inside of the mounting cavity is provided on the side wall of the support platform, and the end of each traction rope away from the isolation cover passes through the makeshift channel and is connected to the rotating disk.

[0022] By adopting the above technical solution, the output end of the rotating motor is started to drive the rotating disk to rotate forward, and the rotating disk gradually increases the traction force on the traction rope, so that all the sliding plates are synchronously separated from the isolation cover; at this time, the rotating motor can be used to drive the traction rope to maintain the above state, so that the sliding plate remains separated from the isolation cover and the elastic member is in a compressed state, thereby facilitating the subsequent detection of the RF transceiver to be tested; when the output end of the rotating motor is controlled to drive the rotating disk to reverse, the traction force of the rotating disk on the traction rope gradually decreases, so that the traction force of the traction rope on the sliding plate gradually decreases, and the sliding plate can be driven by the elastic force of the elastic member to move quickly toward the isolation cover.

[0023] Preferably, the outer wall of the isolation cover is provided with several groups of heat sinks, the outer wall of the isolation cover is provided with a ventilation ring pipe, the ventilation ring pipe has several groups of ventilation openings penetrating the side wall toward the heat sink, and the ventilation ring pipe is provided with an exhaust fan.

[0024] By adopting the above technical solution, the heat sink can quickly conduct the heat inside the isolation cover for heat dissipation, and the heat sink is blown by the exhaust fan and the ventilation ring pipe, which improves the heat dissipation effect of the heat sink and reduces the accumulation of heat inside the isolation cover during the detection process.

[0025] Preferably, the outer side wall of the isolation cover is provided with an extended ring plate, the side wall of the supporting platform is provided with a mounting ring groove for the extended ring plate to be pressed into, the inner side wall of the mounting ring groove is provided with a flexible ring plate for isolating electromagnetics, and the side wall of the flexible ring plate is pressed against the side wall of the extended ring plate toward the driving member.

[0026] By adopting the above technical solution, the driving member drives the isolation cover to gradually enter the inside of the mounting ring groove, and the extended ring plate abuts the flexible ring plate, causing the flexible ring plate to undergo elastic deformation, and the extended ring plate to move to the bottom of the flexible ring plate, and the flexible ring plate and the extended ring plate abut against the side wall of the driving member, thereby realizing the use of the flexible ring plate with electromagnetic shielding effect to close the gap between the isolation cover and the supporting platform, further reducing the external electromagnetic interference to the radio frequency transceiver.

[0028] 1. By controlling the output end of the driver to extend, the RF transceiver on the carrier is covered with an isolation cover that isolates electromagnetic and signals, and then the gap between the isolation cover and the carrier is sealed with a sealing component, thereby reducing the external electromagnetic interference to the RF transceiver and isolating the signals transmitted and received by the RF transceiver.
