Description

Technical Field

[0001] This application relates to the field of pulse technology, and in particular to an adjustable drive device for switching and resetting a radio frequency switch and a radio frequency switch. Background Technology

[0002] Radio frequency (RF) mechanical switches are key basic components for switching RF signal paths and are widely used in wireless communication systems, RF test equipment, radar detection devices, and other fields. The accuracy and stability of their reset action directly affect the reliability of RF signal transmission and the overall service life of the switch.

[0003] In existing technologies, radio frequency mechanical switches generally adopt a fixed spring reset structure. This structure mainly consists of a support base, a channel switching plate, and a reset spring. The support base is fixedly installed on the switch panel, and the channel switching plate is rotatably mounted above the support base. One end of the reset spring is fixedly connected to the support base, and the other end abuts against one side of the channel switching plate. During operation, the electromagnet and permanent magnet combination is energized to generate a magnetic field, which drives the channel switching plate to rotate around the central axis to switch to the target signal channel. When the electromagnet is de-energized, the reset spring releases the pre-stored elastic potential energy, pushing the channel switching plate back to the initial channel position, completing the reset process.

[0004] Since the spring force coefficient, installation position, and working stroke of the return spring are completely fixed after assembly, in order to ensure the reset accuracy of the channel switching plate and the reset consistency between different channels, stringent requirements must be placed on the machining and assembly accuracy of all related parts such as the channel switching plate, return spring, and support base. This not only significantly increases the manufacturing cost of the product but also leads to a sharp decline in production yield. At the same time, after long-term repeated stress, the return spring will experience elastic fatigue and permanent deformation, causing irreversible deviations in the reset rebound force and reset stroke, which cannot be compensated for by later adjustments. Ultimately, this will lead to inaccurate switch reset or even complete failure, severely shortening the service life of the switch. Summary of the Invention

[0005] In order to achieve independent dynamic adjustment of reset rebound force and reset stroke, this application provides an adjustable drive device for switching reset of radio frequency switch and radio frequency switch.

[0006] The radio frequency switch switching and reset adjustable drive device provided in this application adopts the following technical solution:

[0007] An adjustable drive device for switching and resetting radio frequency switches includes an adjustment seat mounted on a support base. The adjustment seat is movable on the support base along a first direction perpendicular to the mounting reference plane of the support base and a second direction along the horizontal projection length of the channel switching plate. An elastic beryllium copper sheet is fixed on the adjustment seat, and the free end of the elastic beryllium copper sheet abuts against a pin on the channel switching plate. A locking mechanism is provided between the support base and the adjustment seat to lock the position of the adjustment seat after it has moved.

[0008] Preferably, the adjusting seat has a cross groove, and the locking mechanism includes a side plate and a locking screw. The side plate is fixed on the support seat and located at both ends of the cross groove opening. The inner side of the side plate is in contact with the end face of the adjusting seat. The locking screw passes through the side plate near its screw head and is threadedly connected to the side plate away from its screw head.

[0009] Preferably, the system further includes a base, on which a first guide rod extending in a second direction is fixedly mounted on the end face of the support seat, and the base is slidably sleeved on the first guide rod; a second guide rod extending in a first direction is fixedly mounted on the base, and the adjusting seat is slidably sleeved on the second guide rod; the locking mechanism includes a first locking plate rotatably mounted on the base, a second locking plate rotatably mounted on the adjusting seat, and an elastic component, wherein the first locking plate abuts against the first guide rod, the second locking plate abuts against the second guide rod, and the elastic component applies a restoring force toward the support seat to the base and a restoring force toward the base to the adjusting seat, and drives the first locking plate to press against the first guide rod and the second locking plate to press against the second guide rod.

[0010] Preferably, the elastic component includes an elastic rope, a collar, and a guide wheel. The collar is fixedly disposed at the extended end of the first locking plate, and the guide wheel is fixedly disposed on the rotating shaft of the second locking plate. One end of the elastic rope is fixed to the guide wheel, and the other end passes through the collar and is fixed to the side of the support base. The tension of the elastic rope causes the guide wheel to maintain the tendency to drive the second locking plate to deflect, and causes the extended end of the first locking plate to maintain the tendency to rotate outward.

[0011] Preferably, the base is provided with top rods on the upper and lower sides of the first locking plate, the elastic rope passes through the top rods, and the distance from the support contact point of the elastic rope and the top rod to the side of the base is greater than the distance from the collar to the side of the base.

[0012] Preferably, the adjusting seat has an opening groove, and the elastic beryllium copper sheet is pressed and fixed in the opening groove.

[0013] The RF switch provided in this application adopts the following technical solution: an RF switch includes a housing, a channel switching plate, and any of the above-mentioned RF switch switching and reset adjustable driving devices. The housing is covered outside the support base, the channel switching plate is rotatably connected to the support base, and the adjustment base is disposed at one end of the channel switching plate. The elastic beryllium copper sheet is U-shaped, and the channel switching plate is provided with a pin. The free end of the U-shaped elastic beryllium copper sheet is located below the pin and abuts against the pin.

[0014] Preferably, a first guide groove extending laterally is provided on the housing at a position corresponding to the first locking plate, and a horizontal adjusting rod is slidably connected in the first guide groove, the end of the horizontal adjusting rod being threadedly connected to the protruding end of the first locking plate.

[0015] Preferably, a gear is coaxially fixed on the rotating shaft of the second locking plate, and a rack that meshes with the gear is slidably disposed in the adjusting seat. The rack is parallel to the first guide rod and one end extends out of the adjusting seat and is provided with a guide slope. When the rack retracts into the adjusting seat, it drives the second locking plate to rotate to release the second locking plate from locking the second guide rod. A vertically extending second guide groove is provided on the housing, and a vertical adjusting rod is slidably connected in the second guide groove. The vertical adjusting rod includes a sleeve and a telescopic rod. The sleeve and the telescopic rod are anti-rotationally engaged and slidably connected along the axial direction. The end of the telescopic rod is rotatably connected to the adjusting seat, and the rotatable connection point is located on the same end face of the adjusting seat as the end of the rack that extends out. A deflection plate is fixed to the end of the telescopic rod. The deflection plate cooperates with the guide slope. When the vertical adjusting rod is rotated, the deflection plate presses the rack into the adjusting seat along the guide slope.

[0016] Preferably, a first electromagnet and a second electromagnet are provided inside the housing above both ends of the channel switching plate, and the magnetic poles generated by the first electromagnet and the second electromagnet are opposite in direction when energized.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By adjusting the independent movement of the adjustment seat in the first and second directions, the contact height and force point position between the elastic beryllium copper sheet and the pin can be adjusted respectively, thereby independently adjusting the reset stroke and rebound force. This replaces the fixed spring, eliminating the inaccuracy and failure of reset caused by the precision of parts and elastic fatigue. While improving the consistency of reset, it significantly reduces the manufacturing cost and assembly difficulty.

[0019] 2. When the performance of the switch deteriorates after long-term use, there is no need to replace any parts. Simply recalibrate the position of the elastic beryllium copper sheet through the external adjustment rod to restore the performance, which extends the effective service life and reduces the total life cycle maintenance cost.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0029] Example 1

[0030] This embodiment discloses an adjustable driving device for switching and resetting a radio frequency switch, and based on this, provides a radio frequency switch including the driving device. (Refer to...) Figure 1 as well as Figure 2 The drive device includes a support base 1, an adjustment base 2, an elastic beryllium copper sheet 21, and a locking mechanism 3.

[0031] The support base 1 serves as the mounting foundation, with its mounting reference plane being horizontal. The adjusting seat 2 is mounted on the support base 1 and can move relative to the support base 1 along a first direction and a second direction. The first direction is perpendicular to the mounting reference plane of the support base 1, i.e., the vertical direction; the second direction is parallel to the length of the horizontal projection of the channel switching plate 41, i.e., the horizontal direction. An elastic beryllium copper sheet 21 is fixed on the adjusting seat 2. The elastic beryllium copper sheet 21 has a free end, which is used to abut against the pin 411 on the channel switching plate 41. A locking mechanism 3 is provided between the support base 1 and the adjusting seat 2 to lock the adjusting seat 2 in that position after it has moved to the target position along the first or second direction, preventing positional deviation due to external factors such as vibration.

[0032] Specifically, refer to Figure 2 as well as Figure 3 The adjusting seat 2 has a cross groove 24, which extends through the adjusting seat 2 along the width direction of the support seat 1. The cross groove 24 provides guidance and limitation for the combined displacement of the adjusting seat 2 in the first and second directions. The locking mechanism 3 includes side plates 31 and locking screws 32. The side plates 31 are fixedly mounted on the support seat 1 and symmetrically arranged at both ends of the opening of the cross groove 24. The inner surfaces of the two side plates 31 are tightly fitted with the two opposite end faces of the adjusting seat 2. During assembly, the locking screws 32 pass through the open hole on the first side plate 31 closest to its screw head and are threadedly connected to the threaded hole on the second side plate 31 furthest from its screw head. When adjustment is required, loosen the locking screw 32, and the clamping force of the two side plates 31 on the end face of the adjusting seat 2 will disappear. The adjusting seat 2 can then move freely in the first or second direction within the range defined by the cross groove 24. After adjustment, tighten the locking screw 32 again. The preload of the screw forces the two side plates 31 to press against the end face of the adjusting seat 2, and stepless locking is achieved by relying on the friction between the contact surfaces.

[0033] For the fixing method of the elastic beryllium copper sheet 21, an open slot 22 is provided on the adjusting seat 2. During assembly, the fixing end of the elastic beryllium copper sheet 21 is fully inserted into the open slot 22 and fixed by clamping. As a preferred clamping method, the adjusting seat 2 is provided with a fixing screw 23. The screw shank of the fixing screw 23 passes through the pre-drilled through hole on the elastic beryllium copper sheet 21 and is threadedly connected to the threaded hole on the adjusting seat 2. The axis of the fixing screw 23 is perpendicular to the surface of the elastic beryllium copper sheet 21. When the fixing screw 23 is tightened, the head of the fixing screw 23 presses the elastic beryllium copper sheet 21 into the groove wall of the open slot 22, forming an omnidirectional rigid constraint, ensuring the long-term stability and repeatability of the contact state between the free end of the elastic beryllium copper sheet 21 and the pin 411.

[0034] This embodiment also provides a radio frequency switch, which includes a housing 4, a channel switching plate 41, and a driving device with the above-described structure. The housing 4 is covered outside the support base 1, and the channel switching plate 41 is rotatably connected to the support base 1 via a rotating shaft. An adjusting seat 2 is located below one end of the channel switching plate 41, and the elastic beryllium copper sheet 21 is U-shaped, with its free end located directly below the pin 411 on the channel switching plate 41 and elastically abutting against the pin 411. A first electromagnet 42 and a second electromagnet 43 are fixed above both ends of the channel switching plate 41 inside the housing 4. The coil winding direction or energizing direction of the first electromagnet 42 and the second electromagnet 43 is set so that when both are energized simultaneously, the magnetic poles generated above both ends of the channel switching plate 41 are in opposite directions, thereby generating electromagnetic torques in the same direction, forming a resultant force to drive the channel switching plate 41 to rotate to complete the signal channel switching.

[0035] The implementation principle of this embodiment is as follows: When it is necessary to adjust the reset stroke or rebound force, loosen the locking screw 32 to release the clamping of the side plate 31 on the adjusting seat 2; then push the adjusting seat 2 to move along the cross groove 24 in the first or second direction, changing the support height of the U-shaped free end of the elastic beryllium copper sheet 21 or the lever arm length in contact with the pin 411, thereby independently adjusting the reset stroke and rebound force; after adjustment, tighten the locking screw 32 to lock it. During operation, the first electromagnet 42 and the second electromagnet 43 are energized simultaneously, driving the channel switching plate 41 to overcome the elastic force of the elastic beryllium copper sheet 21 and rotate to switch channels; after power is cut off, the elastic beryllium copper sheet 21 releases its elastic potential energy, precisely pushing the channel switching plate 41 back to its initial position.

[0036] Example 2

[0037] This embodiment discloses another adjustable drive device for switching and resetting radio frequency switches. Based on embodiment 1, it adopts a different locking mechanism 3, decouples the two-dimensional adjustment motion by adding a base 5 and a split guide rod structure, and constructs a linkage locking mechanism 3; at the same time, it provides a radio frequency switch with external adjustment function.

[0038] Reference Figure 4 as well as Figure 5 The driving device includes a support base 1, a base 5, an adjusting seat 2, and an elastic beryllium copper sheet 21. A first guide rod 11 extending in a second direction is fixed to the end face of the support base 1. The base 5 is slidably sleeved on the first guide rod 11, allowing the base 5 and the components it supports to move horizontally relative to the support base 1 as a whole. A second guide rod 51 extending in a first direction is fixed to the base 5. The adjusting seat 2 is slidably sleeved on the second guide rod 51, allowing the adjusting seat 2 to move vertically within the base 5. In this way, the movement of the adjusting seat 2 in the first and second directions is constrained by the second guide rod 51 and the first guide rod 11, respectively, achieving complete decoupling of the two-dimensional motion.

[0039] Reference Figure 6 as well as Figure 7 The locking mechanism 3 includes a first locking plate 33 rotatably mounted on the base 5, a second locking plate 34 rotatably mounted on the adjusting seat 2, and an elastic component 6. Driven by the elastic component 6, the first locking plate 33 always tends to rotate inward and press against the first guide rod 11, and the second locking plate 34 always tends to rotate inward and press against the second guide rod 51. Simultaneously, the elastic component 6 applies a restoring force to the base 5 that is always directed towards the support seat 1, and applies a restoring force to the adjusting seat 2 that is always directed towards the bottom of the base 5. Under normal conditions without external force intervention, the first locking plate 33 and the second locking plate 34 form friction self-locking with their respective guide rods, locking the base 5 and the adjusting seat 2 in their current positions.

[0040] Reference Figure 8A receiving groove 52 is provided on one side of the base 5, which communicates with the mounting hole of the first guide rod 11. The middle part of the first locking plate 33 is rotatably disposed in the receiving groove 52. One end of the first locking plate 33 abuts against the first guide rod 11, and the other end is located outside the base plate. The first locking plate 33 and the first guide rod 11 are inclined relative to each other to form a barbed limiting structure, and the limiting direction is the same as the driving direction of the elastic component 6, thereby realizing the fixation between the base 5 and the first guide rod 11. The installation and limiting principle of the second locking plate 34 are similar to those of the first locking plate 33.

[0041] The elastic component 6 specifically consists of an elastic rope 61, a collar 62, and a guide wheel 63. The collar 62 is fixedly installed on the protruding end of the first locking plate 33, and the guide wheel 63 is fixedly installed on the rotating shaft of the second locking plate 34. One end of the elastic rope 61 is wound around and fixed to the guide wheel 63. After the rope passes over the guide wheel 63, the free end passes through the collar 62 and is finally fixed to the side of the support base 1. During the sliding process of the base 5 and the adjusting seat 2, the elastic rope 61 always remains taut. To achieve reliable fixation, a fixing block is provided on the side of the support base 1, and the end of the elastic rope 61 is fixed to the fixing block by means of fastening, pressing, or bonding.

[0042] The elastic rope 61 generates tension in its pre-stretched state. This tension acts on the guide wheel 63, producing a continuous deflection torque on the shaft of the second locking plate 34, driving the second locking plate 34 to press against the second guide rod 51. Simultaneously, the tension generates an outward pulling torque on the extended end of the first locking plate 33 through the collar 62, driving the first locking plate 33 to press against the first guide rod 11. To enhance the locking reliability of the first locking plate 33, top rods 53 are respectively provided on the base 5, located on the upper and lower sides of the first locking plate 33. The elastic rope 61 passes between these two top rods 53 before passing through the collar 62. Due to the lifting effect of the top rods 53, the vertical distance from the support contact point of the elastic rope 61 and the top rod 53 to the side of the base 5 is greater than the vertical distance from the collar 62 to the side of the base 5. This arrangement increases the deflection arm of the first locking plate 33, achieving a larger locking torque under the same rope tension and improving the margin against vibration and loosening.

[0043] This embodiment also provides a radio frequency switch, including a housing 4, a channel switching plate 41, and the aforementioned drive device having a base 5 and a decoupling guide rod.

[0044] To enable direct adjustment from outside the housing 4, a first guide groove 44 extending laterally is provided on the housing 4 at a position corresponding to the protruding end of the first locking plate 33. A horizontal adjustment rod 7 is slidably connected within the first guide groove 44, and the inner end of the horizontal adjustment rod 7 is threadedly connected to the protruding end of the first locking plate 33. When horizontal adjustment is required, the operator presses the horizontal adjustment rod 7, causing it to push the first locking plate 33 to rotate against the tension of the elastic rope 61, thus releasing the lock on the first guide rod 11. Subsequently, sliding the horizontal adjustment rod 7 along the first guide groove 44 will cause the base 5 and the adjustment seat 2 to move as a whole in the second direction, changing the contact arm between the elastic beryllium copper sheet 21 and the pin 411, thereby achieving stepless external adjustment of the rebound force.

[0045] For vertical adjustment, a gear 8 is coaxially fixed on the shaft of the second locking plate 34. A rack 81, meshing with the gear 8, is slidably disposed inside the adjusting seat 2. The rack 81 is arranged parallel to the first guide rod 11. One end of the rack 81 extends out of the end face of the adjusting seat 2, and a guide slope 811 is machined on this extended end. When unlocking, the inward movement of the rack 81 drives the gear 8 to rotate, which in turn drives the second locking plate 34 to rotate against the tension of the elastic rope 61, thus releasing the lock on the second guide rod 51.

[0046] A vertically extending second guide groove 45 is provided on the housing 4, and a vertical adjusting rod 9 is slidably connected within the second guide groove 45. The vertical adjusting rod 9 consists of a sleeve 92 and a telescopic rod 91. The sleeve 92 and the telescopic rod 91 are in a non-rotating fit and can slide freely along the axial direction, for example, using a spline or square shaft fit. The vertical adjusting rod 9 is arranged parallel to the first guide rod 11. The bottom end of the telescopic rod 91 is rotatably connected to the end face of the adjusting seat 2, and this rotatable connection point is the same end face as the end face of the rack 81 extending out of the adjusting seat 2. A deflection plate 94 is also fixed to the bottom end of the telescopic rod 91, and the edge of the deflection plate 94 is spatially matched with the guide slope 811 of the rack 81. When vertical adjustment is required, the operator rotates the handwheel 93 at the end of the vertical adjustment rod 9, and the deflection plate 94 rotates accordingly and presses the rack 81 into the adjustment seat 2 along the guide slope 811; at this time, the vertical adjustment rod 9 is pushed and pulled vertically, and the telescopic rod 91 drives the adjustment seat 2 to move vertically along the second guide rod 51, while the sliding between the sleeve 92 and the telescopic rod 91 automatically compensates for the positional change caused by the horizontal movement of the base 5.

[0047] After adjustment, the vertical adjustment rod 9 is rotated in the opposite direction, causing the deflection plate 94 to disengage from the end of the rack 81. The tension of the elastic rope 61 automatically drives the second locking plate 34 to reset and relock. This solution allows for external unlocking and adjustment in the vertical direction through rotation and push-pull, making it easy to operate.

[0048] The implementation principle of this embodiment is as follows: During calibration, horizontal adjustment is achieved by pressing and sliding the horizontal adjustment rod 7, and vertical adjustment is achieved by rotating the vertical adjustment rod 9 to push the rack 81 to unlock and then pushing and pulling. During the adjustment process, the elastic rope 61 always provides a restoring force and automatically locks. When the switch is working, the first electromagnet 42 and the second electromagnet 43 are energized, driving the channel switching plate 41 to rotate and switch channels. After power is cut off, the U-shaped elastic beryllium copper sheet 21 pushes the channel switching plate 41 to precisely reset via the pin 411.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
