It should be noted that the features of the embodiments of the present utility model may be combined with each other without conflict.
Referring to fig. 1, an antenna scanning apparatus 10 is provided in an embodiment of the present utility model, where the antenna scanning apparatus 10 is used for testing wireless performance of a large-sized object, and the large-sized object may be a base station antenna or a vehicle.
Because the antenna scanning device is applied to the wireless performance test of larger equipment, the volume and the weight of the antenna scanning device are larger, driving components such as a motor in the antenna scanning device are required to provide larger driving force, and the load born by the driving components is higher, so that the control precision, the cost, the complexity, the noise and the like of the driving components are influenced. In the prior art, it is difficult to balance the above factors, resulting in poor user experience of the antenna scanning device.
The antenna scanning device 10 provided by the present utility model can improve the above technical problems, that is, the antenna scanning device 10 provided by the embodiment of the present utility model can improve the problems of the load and precision requirements of the motor, the cost, complexity and noise of the motor in the prior art, which are difficult to balance.
In the present embodiment, the antenna scanning apparatus 10 includes a base 100, a driving apparatus 300, a moving member 200, and a weight mechanism 400. The moving member 200 is provided with a plurality of test antennas 210 at intervals, and the test antennas 210 can be used for performing signal interaction with the device to be tested so as to realize wireless performance test of the device to be tested. The moving member 200 is movably connected to the base 100 and can slide along a preset direction relative to the base 100; the preset direction is not horizontal. Through the movement of the moving member 200 relative to the base 100, the position of the test antenna 210 on the moving member 200 can be adjusted, so that the test angle of the device to be tested can be adjusted, and the wireless performance test can be conveniently and comprehensively completed. The driving device 300 is disposed on the base 100, and the driving device 300 is in transmission connection with the moving member 200, so as to drive the moving member 200 to move relative to the base 100.
It should be noted that, because the preset direction is not horizontal, at least a part of the force component acts on the driving device 300 due to the gravity of the moving member 200, the driving force provided by the driving device 300 needs to overcome the influence of the gravity of the moving member 200, and based on this, the load of the driving device 300 is larger, which affects the control accuracy of the driving device 300; in order to ensure efficient operation of the driving device 300, the cost and complexity of the driving device 300 need to be increased, and the use of a large driving device 300 causes a problem of high noise.
In this embodiment, the weight mechanism 400 is connected to the moving member 200 to apply a force to the moving member 200 opposite to the direction of gravity of the moving member 200. That is, part of the gravity of the moving member 200 is offset by the weight mechanism 400, so that the influence of the gravity of the moving member 200 on the driving device 300 is reduced, the load of the driving device 300 is reduced, and the influence on the control accuracy of the driving device 300 is reduced; the cost and complexity of the driving device 300 are not increased, and the noise problem caused by the large driving device 300 can be avoided.
In the above-mentioned manner, in the antenna scanning device 10, since the preset direction is a non-horizontal direction, when the driving device 300 drives the moving member 200 to move along the preset direction, the gravity of the moving member 200 acts on the driving device 300, and the driving device 300 needs to provide the driving force to the moving member 200 against the gravity of the moving member 200; in the case of application to a large-sized moving member 200, the driving device 300 is caused to provide a larger driving force; however, in the case where the weight mechanism 400 is provided, a force opposite to the direction of gravity of the moving member 200 may be provided by the weight mechanism 400 to eliminate at least part of the gravity applied to the driving device 300 by the moving member 200, so that the load of the driving member may be reduced, the load of the driving device 300 may be reduced without increasing the cost and complexity of the driving device 300, and the accuracy control of the driving device 300 may be improved; and simultaneously, the noise can be reduced. Based on the above, the problems of the prior art that the load and precision requirements of the motor are difficultly balanced with the cost, complexity and noise of the motor can be solved.
In addition, the weight mechanism 400 applies a force to the moving member 200 opposite to the gravitational direction, which may be vertically upward, or may be obliquely upward, or may be regarded as non-horizontal.
Optionally, referring to fig. 1 and 2 in combination, in the present embodiment, the weight mechanism 400 includes a driving wheel 430, a traction rope 420, and a weight 410; one end of the traction rope 420 is connected to the moving member 200, and the other end is connected to the balancing weight 410; the traction rope 420 is wound around the driving wheel 430, so that the traction rope 420 pulls the moving member 200 in a direction opposite to the gravity direction of the moving member 200. That is, the weight 410 is converted into a force opposite to the gravity direction of the moving member 200 by means of the traction rope 420 and the driving wheel 430, so that the weight 410 applies a force opposite to the gravity direction of the moving member 200 to the moving member 200, and at least part of the gravity of the moving member 200 can be offset. The weight mechanism 400 has a simple structure, is easy to implement, and can reduce cost input.
In the case of fig. 1 as an example, the number of driving wheels 430 is two, and the traction rope 420 bypasses the two driving wheels 430 to make the balancing weight 410 have a certain distance from the seat body 100, so that the balancing weight 410 is convenient to be arranged at a position, and the mutual interference between the balancing weight 410 and the seat body 100 is avoided. Of course, in other embodiments, the traction rope 420 and the driving wheel 430 may be arranged in other manners, and the length of the traction rope 420 and the number of driving wheels 430 may be set according to the actual situation, so that the direction of the force applied by the traction rope 420 to the moving member 200, the position of the balancing weight 410, and the like may be adjusted.
In this embodiment, the weight 410 has a weight less than the weight of the moving member 200. To prevent excessive weight of the weight 410 from affecting movement of the mover 200. In this embodiment, only the moving member 200 is required to counteract the weight of a portion of the moving member 200.
In this embodiment, the counterweight mechanism 400 further includes a guide structure 440, and the counterweight 410 is slidably connected to the guide structure 440. By restricting the weight 410 by the guide structure 440, the fluctuation of the force applied to the moving member 200 due to the shaking of the weight 410 can be prevented from greatly affecting the driving stability of the driving device 300. In other words, the stability of the force applied to the moving member 200 by the weight 410 can be ensured, and the overall stability of the antenna scanning apparatus 10 can be ensured.
Optionally, the guide structure 440 includes a support frame and a slider 442; the support frame is provided with a guide rail 441, a sliding block 442 is slidably connected to the guide rail 441, and the balancing weight 410 is fixedly connected with the sliding block 442. It should be noted that, in the present embodiment, the guide rail 441 is configured to extend along a straight line, so that the slider 442 can move along the straight line; meanwhile, a section of the traction rope 420 connected to the balancing weight 410 is parallel to the guide rail 441; based on this, during the sliding process of the sliding block 442 along the guide rail 441, the angle of the length of the traction rope 420 connected to the weight 410 with respect to the vertical direction is unchanged, so that the acting force of the weight 410 applied to the moving member 200 through the traction rope 420 can be kept constant, and the influence of the change of the acting force applied to the moving member 200 on the driving stability of the driving device 300 is prevented.
In addition, in the embodiment of the present utility model, two opposite sides of the support frame are provided with guide rails 441, and two guide rails 441 are provided with sliding blocks 442; opposite sides of the counterweight 410 are fixedly connected with the sliding blocks 442 on the two sides respectively. By providing slide 442 and guide rail 441 on both sides of counterweight 410, the stability of counterweight 410 movement can be further improved. In addition, the sliding of the slider 442 is prevented from being blocked, and smooth movement of the weight 410 is ensured.
In the present embodiment, the moving member 200 has at least one limit position with respect to the movement range of the base 100; the guiding structure 440 further includes a limiting structure (not shown), which is disposed on the guide rail 441, and the sliding block 442 abuts against the limiting structure when the moving member 200 moves to the limit position. It should be noted that, in the present embodiment, the moving member 200 has two extreme positions relative to the base 100, and the two extreme positions define the movement range of the moving member 200 relative to the base 100. Correspondingly, two corresponding limiting structures are arranged on the guide rail 441; in the case that the moving member 200 moves to one of the limit positions, the sliding block 442 abuts against one of the limit structures; and when the moving member 200 moves to the other limit position, the sliding block 442 abuts against the other limit structure. And, during the sliding of the moving member 200 between the two extreme positions, the sliding block 442 slides between the two limiting structures.
The positions of the two limiting structures on the guide rail 441 may be determined according to the movement range of the moving member 200 between the two limiting positions on the base 100, so as to ensure that the sliding block 442 abuts against the limiting structures when the moving member 200 is at the limiting position.
In addition, in the embodiment of the present utility model, the weight 410 includes a plurality of weight parts 411; the plurality of weight portions 411 are each detachably connected to the slider 442, and based on this, the force applied to the mover 200 can be reduced by removing the weight portions 411; the force applied to the mover 200 may be raised by adding the weight 411, in other words, the number of the weights 411 may be removed or increased according to the actual situation of the mover 200, and the force applied to the mover 200 may be adjusted. In addition, at least one weight 411 is connected to the traction rope 420 to transmit the force to the mover 200 through the traction rope 420.
It should be appreciated that in other embodiments of the present utility model, adjustment of the weight 410 weight may be accomplished in other ways. For example, by increasing the friction between slider 442 and rail 441, etc.
In this embodiment, the seat 100 is provided with a concave sliding arc surface, the moving member 200 is arc-shaped, and the convex side of the moving member 200 is in sliding fit with the sliding arc surface; the test antenna 210 is disposed at a concave side of the moving member 200. That is, the preset direction is an arc direction. The antenna scanning device 10 further comprises a turntable 500, and one side of the moving member 200, on which the test antenna 210 is arranged, is arranged towards the turntable 500; the turntable 500 is used for carrying a workpiece and driving the workpiece to rotate. Of course, in other embodiments, the setting of the turntable 500 may be eliminated.
Further, a weight mechanism 400 is attached to the bottom of the mover 200. In the case of taking fig. 1 as an example, the bottom of the moving member 200 is in a substantially vertical state, and based on this, the weight mechanism 400 is connected to the bottom of the moving member 200, so that the gravity of the moving member 200 can be effectively offset from the vertical direction, thereby achieving the problem of improving the load and precision requirements of the motor and the difficulty in balancing the cost, complexity and noise of the motor in the prior art.
In summary, in the antenna scanning device 10, since the preset direction is a non-horizontal direction, when the driving device 300 drives the moving member 200 to move along the preset direction, the gravity of the moving member 200 acts on the driving device 300, and the driving device 300 needs to provide the driving force to the moving member 200 against the gravity of the moving member 200; in the case of application to a large-sized moving member 200, the driving device 300 is caused to provide a larger driving force; however, in the case where the weight mechanism 400 is provided, a force opposite to the direction of gravity of the moving member 200 can be provided by the weight mechanism 400 to eliminate the gravity applied to the driving device 300 by at least part of the moving member 200, so that the load of the driving member can be reduced, the load of the driving device 300 can be reduced without increasing the cost and complexity of the driving device 300, and the accuracy control of the driving device 300 can be improved, and accordingly the accuracy of the wireless test can be improved; and simultaneously, the noise can be reduced. Based on the above, the problems of the prior art that the load and precision requirements of the motor are difficultly balanced with the cost, complexity and noise of the motor can be solved.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model.
