Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of test equipment, in particular to a multi-dimensional test support table. BACKGROUND

[0002] Some communication devices (such as routers, etc.) related to antennas need to be tested in a microwave anechoic chamber, and a support table is often provided in the microwave anechoic chamber to support the tested object so that the tested object is in a specific position in the microwave anechoic chamber;

The height of the test table can be adjusted, and the angle of the test table can be adjusted.

[0004] In practice, in order to improve the comprehensiveness and effectiveness of the test results, the tested object needs to be rotated horizontally during the test process. However, since the tested object is connected to the corresponding transmission cable, the rotating disc cannot be continuously rotated in the same direction. The common method is to set a rotating disc supporting the tested object on the lifting platform, and set a position sensor at the starting position and the end position of the rotating disc, so that the rotating disc reciprocates and deflects between the two position sensors.

[0005] However, the existing scheme has the following disadvantages: since the rotating path of the rotating disc is a circular arc, the rotating stroke of the rotating disc is limited by the two sensors. No matter how the two sensors are arranged, the rotating angle of the rotating disc is always less than 360 degrees, so that there is always a test blind area for the tested object on the rotating disc, and the test results are not comprehensive enough.

DETAILED DESCRIPTION

[0030] In order for those skilled in the art to better understand the technical solutions of the application, the application will be further described in detail below with reference to the drawings.

[0031] The microwave darkroom is a special room composed of wave-absorbing materials and metal shielding bodies, and is provided with a receiving antenna close to the wall in the room. The platform capable of lifting and rotating is generally located in the middle of the room, and the communication equipment (such as a router) and the like is tested in the microwave darkroom. When the communication equipment (such as a router) and the like is tested, the measured object such as a router is placed on the platform capable of lifting and rotating, and then the measured object is connected with the radio frequency cable on the platform capable of lifting and rotating, so that the measured object can emit signals and be received by the receiving antenna, and the rotating measured object can make each surface of the measured object successively face the receiving antenna, thereby realizing omnidirectional measurement of electromagnetic radiation.

[0032] However, since the measured object is connected with the corresponding transmission cable, that is, the radio frequency cable, the rotating disc cannot continuously rotate in the same direction. At present, a common method is to set the rotating disc supporting the measured object on the lifting platform, and set a position sensor at the starting position and the terminal position of the rotating disc respectively, so that the rotating disc reciprocates and deflects between the two position sensors.

[0033] However, the existing scheme has the following deficiencies: Figure 1As shown, since the rotating path of the rotating disc is an arc, the rotating stroke of the rotating disc is limited by the two sensors, no matter how the two sensors are arranged, the rotating angle of the rotating disc is always less than 360 degrees, so that there is always a test blind area for the measured object on the rotating disc, so that the test result is not comprehensive.

[0034] Please refer to Figures 1-8 The embodiment of the present application provides a kind of multi-dimension test support platform, including lifting platform 1, lifting platform 1 is fixed with base 2, base 2 is rotatably installed with rotating disc 3, rotating disc 3 is fixed with convex unit 4, base 2 is movably installed with trigger unit 5, trigger unit 5 has first stroke and second stroke opposite each other, first stroke and second stroke are each provided with position sensor 6 fixed with base 2, position sensor 6 senses trigger unit 5 and then switches the rotating direction of rotating disc 3, convex unit 4 can provide driving force for the movement of trigger unit 5 on first stroke and second stroke along with the rotation of rotating disc 3;

[0035] Specifically, lifting platform 1 can adjust the height position in vertical direction, the lifting mechanism part of lifting platform 1 in the specification drawing is not drawn, only the platform plate of lifting platform 1, the number of base 2 on lifting platform 1 is 3 to 5, rotating disc 3 can support the tested object, the tested object can also rotate synchronously with rotating disc 3, there is a spacing between the bottom surface of rotating disc 3 and the top surface of lifting platform 1, convex unit 4 is installed on the bottom surface of rotating disc 3, trigger unit 5 can move on base 2 when being pushed by external force, position sensor 6 is signal control connected with the driving motor for driving rotating disc 3 to rotate, when position sensor 6 senses trigger unit 5, the driving motor will change the driving direction;

[0036] In actual use, convex unit 4 rotates synchronously with rotating disc 3 in clockwise direction, when convex unit 4 reaches the position of trigger unit 5, convex unit 4 positively extrudes one side of trigger unit 5 under the driving of the continuous clockwise rotation of rotating disc 3, so that trigger unit 5 positively displaces on first stroke, trigger unit 5 moves from original position to the direction of corresponding position sensor 6, when position sensor 6 senses trigger unit 5, position sensor 6 feeds back signal to the control unit of driving motor, so that the control unit makes the driving motor switch the driving direction, so as to change the rotating direction of rotating disc 3, so that rotating disc 3 rotates in counterclockwise direction, realizing the switching of the rotating direction of rotating disc 3;

[0037] Then convex unit 4 rotates synchronously with rotating disc 3 in counterclockwise direction, convex unit 4 moves away from trigger unit 5 along with the rotation of rotating disc 3, so that trigger unit 5 moves towards original position on first stroke;

[0038] When the protruding unit 4 synchronously rotates counterclockwise with the rotating disc 3 again reaches the position where the trigger unit 5 is located, the protruding unit 4 reversely extrudes the other side of the trigger unit 5 under the driving of the continuous counterclockwise rotation of the rotating disc 3, so that the trigger unit 5 reversely displaces on the second stroke, and the trigger unit 5 moves from the original position to the direction of the other position sensor 6, when the other position sensor 6 senses the trigger unit 5, the position sensor 6 feeds back a signal to the control unit of the driving motor, so that the control unit makes the driving motor switch the driving direction, so as to change the rotating direction of the rotating disc 3, so that the rotating disc 3 rotates clockwise, and the rotating direction of the rotating disc 3 is switched;

[0039] Then the protruding unit 4 synchronously rotates clockwise with the rotating disc 3, and the protruding unit 4 moves away from the trigger unit 5 under the rotation of the rotating disc 3, so that the trigger unit 5 moves to the original position on the second stroke;

[0040] In the whole process, no matter the clockwise rotation of the rotating disc 3 or the counterclockwise rotation of the rotating disc 3, the protruding unit 4 is rotated after passing through the original position of the trigger unit 5, so that the rotating direction of the rotating disc 3 is switched, so as to realize that the rotating stroke of the rotating disc 3 is enlarged, and the rotating angle of the rotating disc 3 is always greater than 360 degrees, as shown in the drawings of the specification, the rotating disc 3 completes a complete revolution, so as to be beneficial to further eliminating the test blind area of the measured object on the rotating disc 3, and improving the comprehensiveness of the test result.

[0042] ​It needs to be further explained that the pipe body of the support pipe 2.3 is fixed with a tooth ring 11, the ring body of the tooth ring 11 is meshed with a gear 12, the support box 2.2 is fixed with a driving motor 13, the output shaft of the driving motor 13 is fixed with the gear 12, so that the driving motor 13 can provide driving force for the rotation of the rotating disc 3 through the meshing transmission of the gear 12 and the tooth ring 11, so that the rotating disc 3 can change the steering according to the driving direction of the driving motor 13.

[0043] In another embodiment of the application, the trigger unit 5 includes a column plate 5.1 fixed on the bottom plate 2.1, the column plate 5.1 is an L-shaped strip plate body, the plate surface of the column plate 5.1 is parallel to the side surface of the support box 2.2, the shaft rod 5.2 is rotatably installed between the column plate 5.1 and the outer side surface of the support box 2.2, the axis of the shaft rod 5.2 is perpendicular to the plate surface of the column plate 5.1 and the outer side surface of the support box 2.2, the gear disc 5.3 is rotatably installed on the shaft rod 5.2, the disc surface of the gear disc 5.3 is parallel to the outer side surface of the support box 2.2, the trigger strip 5.4 capable of entering the sensing area of the position sensor 6 is fixed on the gear disc 5.3, the trigger strip 5.4 is located on the symmetry line between the two position sensors 6 in the initial state, the trigger strip 5.4 is located at the bottom position of the gear disc 5.3, and the protruding unit 4 can drive the gear disc 5.3 to deflect so that the trigger strip 5.4 enters the sensing area of the sensor 6;

[0044] Further, a plurality of through holes 3.1 are formed in the disc body of the rotating disc 3, the through holes 3.1 are uniformly distributed along the circular line of the rotating disc 3, the center of the circular line of the rotating disc 3 coincides with the center of the rotating disc 3, and a cylindrical socket 3.2 is rotatably installed in each through hole 3.1, the bottom end of each cylindrical socket 3.2 extends from the bottom of the rotating disc 3 to form the protruding unit 4, at this time the entire protruding unit 4 is arc-shaped at the bottom of the rotating disc 3, and the arc-shaped gear structure can be engaged with the gear disc 5.3, that is, each cylindrical socket 3.2 protruding from the bottom end of the rotating disc 3 forms a protruding unit 4 with an arc-shaped gear structure, and the teeth of the gear structure of the protruding unit 4 are formed by the cylindrical sockets 3.2 protruding from the bottom end of the rotating disc 3;

[0045] In actual use, for example, when the convex unit 4 passes through the trigger unit 5 along with the rotation of the rotating disc 3, the convex unit 4 with the arc-shaped rack structure and the gear disc 5.3 are positively engaged and rotated, so that the gear disc 5.3 is positively deflected around the shaft 5.2, and the positively deflected gear disc 5.3 drives the trigger strip 5.4 to move towards the sensing area of the position sensor 6, until the position sensor 6 senses the trigger strip 5.4, and then the rotation direction of the rotating disc 3 is reversed, the rotation direction of the rotating disc 3 is switched, then the convex unit 4 is synchronously counterclockwise rotated along with the rotating disc 3, the convex unit 4 with the arc-shaped rack structure and the gear disc 5.3 are reversely engaged and rotated, so that the gear disc 5.3 is reversely deflected around the shaft 5.2, and the trigger strip 5.4 is separated from the sensing area of the position sensor 6;

[0046] Similarly, when the convex unit 4 passes through the trigger unit 5 along with the reverse rotation of the rotating disc 3, the trigger switching process of the rotating process of the rotating disc 3 is the same as the above principle, and is not described herein.

[0047] In another embodiment of the application, the plug-in end of each cylindrical socket 3.2 is located in the through hole 3.1, the plug-in end of the cylindrical socket 3.2 is the end that is plugged with the plug of the tested object, two opposite convex blocks 3.3 are installed on the inner wall above the plug-in end of the cylindrical socket 3.2, the convex blocks 3.3 are preferably ball structures that are movably embedded on the wall of the through hole 3.1, the convex blocks 3.3 can freely rotate on the wall of the through hole 3.1, and the axial rotation of the cylindrical socket 3.2 can drive the plugged plug to be pressed with the convex blocks 3.3, wherein a ring groove is formed in the inner wall of the through hole 3.1, and a limiting block fixed with the cylindrical socket 3.2 is slidably fitted in the ring groove, so that the cylindrical socket 3.2 is rotatably installed in the through hole 3.1.

[0048] Further, the bottom side of the cylindrical socket 3.2 is electrically connected with a delivery cable 3.4, the delivery cable 3.4 is a radio frequency cable, the delivery cable 3.4 is perpendicular to the side of the cylindrical socket 3.2, and the delivery cable 3.4 can provide driving force for the axial rotation of the cylindrical socket 3.2 when it is pulled, the side of the support pipe 2.3 is provided with a through hole 3.5 for the delivery cable 3.4 to pass through, wherein the bottom side of the cylindrical socket 3.2 is provided with a wiring hole 3.6 connected with the delivery cable 3.4, the wiring hole 3.6 is on the same horizontal plane as the through hole 3.5, so as to ensure that the pulling direction of the delivery cable 3.4 is perpendicular to the axis of the cylindrical socket 3.2, in addition, a plurality of wire holes 2.4 are formed in the bottom of the support box 2.2 and pass through the lifting platform 1, each wire hole 2.4 can pass through a single delivery cable 3.4, and the support net frame 3.7 is fixed in the support pipe 2.3 to separate the delivery cables 3.4.

[0049] It needs to be further explained that the side surface of each cylindrical socket 3.2 is connected with a conveying cable 3.4 through a wiring port 3.6, each conveying cable 3.4 extends into the inside of the support tube 2.3 through a through hole 3.5, and then each conveying cable 3.4 respectively corresponds to pass through the wire hole 2.4 to penetrate the bottom of the support box 2.2 and the tabletop of the lifting platform 1, so that the plurality of conveying cables 3.4 are concentrated in the inside of the support tube 2.3, which is conducive to wire harness management;

[0050] In actual use, the plug of the measured object is inserted into the plug-in end of the cylindrical socket 3.2, at this time a part of the plug of the measured object also extends into the through hole 3.1, and the plug of the measured object is located between the two convex blocks 3.3, at this time the conveying cable 3.4 between the wiring port 3.6 and the through hole 3.5 is in a bent state, the orientation of the wiring port 3.6 is not directly opposite to the through hole 3.5, and the wiring port 3.6 and the through hole 3.5 have a certain angle of deviation;

[0051] When the support tube 2.3 rotates axially relative to the support box 2.2, since a part of the conveying cable 3.4 penetrates the wire hole 2.4 on the support box 2.2, and another part of the conveying cable 3.4 penetrates the through hole 3.5 of the support tube 2.3, the conveying cable 3.4 in the support tube 2.3 will be twisted in a spiral, and the conveying cable 3.4 will be contracted to a certain extent, and the conveying cable 3.4 can generate a certain pulling force to the axial direction of the cylindrical socket 3.2 during the contraction process, so that the conveying cable 3.4 between the wiring port 3.6 and the through hole 3.5 changes from the bent state to the straightened state, and the orientation of the wiring port 3.6 is directly opposite to the through hole 3.5. Since the cylindrical socket 3.2 has been axially deflected, the plug of the measured object rotates synchronously with the cylindrical socket 3.2, and the cross section of the plug of the measured object is elliptical, so that the plug of the measured object is extruded and limited by the convex blocks 3.3, which is equivalent to further locking the plug of the measured object, which is conducive to improving the fastening degree of the plug of the measured object and the cylindrical socket 3.2. On the other hand, the axial deflection of the cylindrical socket 3.2 also increases the maximum angle of the spiral twist of the conveying cable 3.4, and reduces the resistance of the conveying cable 3.4 to the deflection of the support tube 2.3.

[0052] In other words, the plug of the measured object is inserted into the cylindrical socket 3.2, and when the support tube 2.3 rotates, the conveying cable 3.4 in the support tube 2.3 is twisted in a spiral, and the twisted conveying cable 3.4 is contracted to a certain extent, and the cylindrical socket 3.2 is axially deflected in the through hole 3.1 due to the contraction force generated by the spiral twist of the conveying cable 3.4;

[0053] Since the plug of the measured object is inserted with the cylindrical socket 3.2, the plug of the measured object will be deflected synchronously with the cylindrical socket 3.2, and the cross section of the plug of the measured object is elliptical, so the plug of the measured object will be extruded with the convex block 3.3 in the deflection, thereby limiting the axial deflection of the cylindrical socket 3.2, and the plug of the measured object will be extruded with the convex block 3.3 in the deflection, which also locks the insertion between the plug of the measured object and the cylindrical socket 3.2 to a certain extent, which is beneficial to improve the fastening degree of the insertion between the cylindrical socket 3.2 and the plug of the measured object;

[0054] On the other hand, the cylindrical socket 3.2 is axially deflected in the through hole 3.1 due to the contraction force generated by the spiral twisting of the conveying cable 3.4, which also increases the maximum angle of the spiral twisting of the conveying cable 3.4 to a certain extent, for example, the support pipe 2.3 originally rotates 90 degrees, and the conveying cable 3.4 also needs to be twisted 90 degrees, and since the cylindrical socket 3.2 can be axially deflected in the through hole 3.1 due to the contraction force generated by the spiral twisting of the conveying cable 3.4, the angle a is generated, so now the support pipe 2.3 rotates 90 degrees, and the degree of the spiral twisting of the conveying cable 3.4 is 90-a degrees, and the smaller the spiral twisting angle of the conveying cable 3.4, the smaller the deflection resistance of the support pipe 2.3, and the protection of the conveying cable 3.4 is also improved.

[0055] In still another embodiment of the present application, the circumferential direction of the base 2 is covered with a shielding baffle 2.5, and the shielding baffle 2.5 is fixed with the column plate 5.1, so as to shield and shield other non-measured objects, reduce the frequency offset generated by the receiving antenna, and improve the accuracy of the test results of the measured object.

[0056] In still another embodiment of the present application, the trigger unit 5 comprises a mounting frame 7 fixed with the base 2, and a trigger rod 8 movably mounted on the mounting frame 7, and a branch block 9 fixed on the trigger rod 8, and the branch block 9 is located on the movement track line of the protruding unit 4, and the protruding unit 4 can extrude the branch block 9 to make the trigger rod 8 enter the sensing area of the position sensor 6;

[0057] Further, the branch block 9 and the mounting frame 7 are provided with a reset spring 10 sleeved on the trigger rod 8, and the reset spring 10 can withdraw the trigger rod 8 from the sensing area of the position sensor 6 after the protruding unit 4 moves away;

[0058] Specifically, the trigger rod 8 is a horizontal rod parallel to the horizontal plane, the branch block 9 is fixed in the middle of the trigger rod 8, the mounting frame 7 is two, the two mounting frames 7 are respectively located on the two sides of the branch block 9, the two mounting frames 7 are fixed with the side surface of the support box 2.2, the mounting frame 7 is a limiting ring sleeve which is slidably sleeved with the trigger rod 8, one end of the reset spring 10 is fixed with the mounting frame 7, and the other end of the reset spring 10 is fixedly connected with the branch block 9;

[0059] In actual use, when the convex unit 4 passes through the trigger unit 5, at this time, the convex unit 4 will exert a horizontal thrust on the branch block 9 along the axis direction of the trigger rod 8, so that the trigger rod 8 moves horizontally along the axis direction, and the reset spring 10 also elastically compresses and deforms, so that the trigger rod 8 extends into the sensing area of the position sensor 6, so that the rotating direction of the rotating disc 3 is switched, then the convex unit 4 moves away from the branch block 9 along with the movement of the rotating disc 3, and at the same time, under the elastic release force of the reset spring 10, the branch block 9 and the trigger rod 8 return to the initial position, and the trigger rod 8 is withdrawn from the sensing area of the position sensor 6.

[0060] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
