[0040] At present, the magnetic field far-field loop antenna is mainly used in the field of automobiles and automobile parts, among which there are clear requirements for the height and distance of the magnetic field far-field loop antenna. For this reason, it is necessary to set up an antenna bracket to fix the magnetic field far-field loop antenna so as to test the X, Y and Z directions of the magnetic field far-field loop line. The existing antenna bracket can usually only test the X or Y direction of the magnetic field far-field loop antenna, and if the Z direction is to be tested, another antenna bracket is required, so that two antenna brackets need to be set up to realize the X, Y and Z direction testing, and the antenna needs to change the test direction frequently during the test process, resulting in the need to frequently replace the antenna bracket, which seriously affects the antenna test efficiency.
[0041] Based on this, the utility model provides an antenna testing device, which aims to solve the problem that the antenna bracket needs to be frequently replaced during antenna testing, resulting in low testing efficiency. Figure 1 This is a structural schematic diagram of the antenna testing device provided by the utility model.
[0042] See also Figure 1In one embodiment of the utility model, the antenna testing device 100 includes a base 1, a support member 2, a first rotating member 3 and a second rotating member 4. The support member 2 is movably installed on the base 1 along the up-down direction. The first rotating member 3 is rotatably installed on the support member 2 around an axis extending along the up-down direction. The second rotating member 4 is rotatably installed on the first rotating member 3 around an axis extending along the horizontal direction, and its rotation angle is adjustable. The second rotating member 4 is provided with a mounting portion for antenna installation.
[0043] The technical solution of the utility model is to set the base 1 so as to install the support member 2, and to adjust the position of the first rotating member 3 in the up-down direction through the movement of the support member 2, and to adjust the horizontal angle of the second rotating member 4 through the movement of the first rotating member 3, and to drive the mounting portion to rotate through the movement of the second rotating member 4 so as to enable the antenna to flip over. In this way, the position of the first rotating member 3 in the up-down direction is adjusted so as to adjust the antenna to the test height, and the horizontal orientation and pitch angle of the antenna are adjusted through the rotation of the first rotating member 3 and the second rotating member 4, so as to quickly test the antenna in the X, Y and Z directions, so that the antenna testing device 100 can quickly switch the test direction of the antenna, avoid frequent replacement of the antenna bracket, and help improve the test efficiency of the antenna, thereby solving the problem of frequent replacement of the antenna bracket during antenna testing, resulting in low test efficiency.
[0044] It should be noted that there are many types of mounting parts. For example, the mounting part may be a mounting hole or a mounting buckle, etc. As long as the antenna can be mounted on the first rotating member 3, the present invention does not limit this.
[0045] In one embodiment of the utility model, the first rotating member 3 includes a rotating sleeve 31 and a rotating seat 32, the rotating sleeve 31 is sleeved on the upper end of the support member 2, and the rotating seat 32 is detachably installed on the upper end of the rotating sleeve 31, wherein the second rotating member 4 is installed on the rotating seat 32. In this way, by setting the rotating sleeve 31, the rotating seat 32 can be rotated relative to the support member 2, so as to drive the first rotating member 3 to rotate around an axis extending in the up and down direction so as to adjust the direction of the antenna, and by setting the rotating seat 32, the second rotating member 4 can be installed, and a detachable structure is adopted so as to be adjusted as needed, which is convenient for subsequent maintenance or replacement.
[0046] Furthermore, the rotating sleeve 31 is provided with a through hole, and the first rotating member 3 also includes a positioning bolt 33 passed through the through hole, for locking the rotating sleeve 31 to the support member 2. In this way, by setting the through hole, the positioning bolt 33 can be threadedly passed through the through hole to position the rotating sleeve 31 to the support member 2, so as to prevent the position of the first rotating member 3 from moving, thereby facilitating testing of the antenna.
[0047] In one embodiment of the utility model, the first rotating member 3 is provided with two rotating arms 34 extending upward, each of the rotating arms 34 is provided with a rotating hole, and the second rotating member 4 includes a mounting seat 41 and two rotating shafts 42 provided at both ends of the mounting seat 41, and each of the rotating shafts 42 is respectively passed through the corresponding rotating holes. In this way, by providing the rotating holes and the rotating shafts 42, the mounting seat 41 can be rotated along an axis extending horizontally to adjust the pitch angle of the antenna, thereby facilitating testing of the antenna.
[0048] In one embodiment of the utility model, the antenna testing device 100 also includes a positioning structure provided between the rotating shaft 42 and the rotating hole, so that the rotation angle of the second rotating member 4 can be adjusted. In this way, by setting the positioning structure, the rotating shaft 42 can be positioned at the test position, so that the rotation angle of the second rotating member 4 can be adjusted, so that the position of the second rotating member 4 can be moved, thereby facilitating the testing of the antenna.
[0049] Furthermore, the positioning structure includes a positioning portion and a matching portion respectively arranged on the inner wall surface of the rotating hole and the rotating shaft 42, and a plurality of the positioning portions and the matching portions are arranged at circumferential intervals along the rotating shaft 42, and one of the positioning portions can be selected to cooperate with the matching portions at different positions so that the rotation angle of the second rotating member 4 can be adjusted. In this way, by setting a plurality of the positioning portions and matching portions that cooperate with each other, the second rotating member 4 can be positioned on the first rotating member 3, which does not affect the rotation of the second rotating member 4 and can position the second rotating member 4 at the test position so as to adjust the pitch angle of the second rotating member 4.
[0050] It should be noted that there are multiple types of positioning structures. In another embodiment, the first positioning member is provided with a fixing hole, and the positioning structure includes a fixing bolt passed through the fixing hole. After the fixing bolt passes through the fixing hole, it abuts against the rotating shaft 42 to tightly fix the rotating shaft 42 to the first positioning member. In this way, by setting the fixing hole and the fixing bolt, after the antenna is adjusted to the test position, the second rotating member 4 is positioned to the first positioning member to prevent the position of the second rotating member 4 from moving.
[0051] In one embodiment of the present invention, the antenna testing device 100 further includes a locking sleeve 5 disposed on the upper end of the base 1, and the lower end of the support member 2 is inserted through the locking sleeve 5 and is interference-connected with the locking sleeve 5. Thus, by providing the locking sleeve 5 so that the lower end of the support member 2 forms an interference fit, the support member 2 can be installed on the base 1, and the support member 2 can be moved in the up and down directions so as to adjust the height of the first rotating member 3. Further, there are multiple ways of connecting the locking sleeve 5 with the base 1. The locking sleeve 5 can be installed on the base 1 by bonding or by screwing, etc., which is not limited by the present invention. Further, the locking sleeve 5 can be detachably installed on the base 1 so that the locking sleeve 5 can be replaced as needed so that the locking sleeve 5 can be adapted to the support member 2 to avoid the clamping force of the locking sleeve 5 being too large or too small. Furthermore, the locking sleeve 5 is made of elastic material, which is convenient for forming an interference fit with the support member 2 and can absorb the impact of the first rotating member 3 to prevent the first rotating member 3 from colliding with the base 1 due to the support member 2 falling.
[0052] In one embodiment of the utility model, the antenna testing device 100 further includes an adjustment sleeve threadedly sleeved on the lower end of the support member 2, so that the position of the support member 2 can be adjusted in the up-down direction. Thus, by setting the adjustment sleeve, the position of the support rod can be adjusted in the up-down direction, thereby adjusting the height of the first rotating member 3. Furthermore, there are multiple settings for the adjustment sleeve, and the adjustment sleeve can be set at the upper end of the base 1 or at the lower end of the base 1. The utility model does not limit this. Specifically, the adjustment sleeve is set at the lower end of the base 1, which can cooperate with the locking sleeve 5 to clamp the support member 2 to the base 1, and is convenient for adjusting the position of the support member 2 in the up-down direction.
[0053] In one embodiment of the utility model, the base 1 includes a bottom plate 11, a mounting plate 12 and a plurality of connecting rod structures 13. The mounting plate 12 can move relative to the bottom plate 11. The plurality of connecting rod structures 13 are arranged at intervals along the circumference of the bottom plate 11. Each of the connecting rod structures 13 can movably connect the bottom plate 11 and the mounting plate 12. In its movable stroke, the connecting rod structure 13 has a folded position that moves toward the mounting plate 12 and a supporting position that moves away from the mounting plate 12 to an upright position. In this way, by providing the connecting rod structure 13, the base 1 can be folded for easy storage or transportation, and the base 1 can be unfolded to support the support member 2, so that the antenna testing device 100 can fix the antenna.
[0054] Furthermore, the connecting rod structure 13 includes a first connecting rod 131 and a second connecting rod 132, one end of the first connecting rod 131 is hinged to the mounting plate 12, one end of the second connecting rod 132 is hinged to the other end of the first connecting rod 131, and the other end is hinged to the bottom plate 11. In this way, by setting the hinged first connecting rod 131 and the second connecting rod 132, the base 1 can be folded together and can be unfolded and supported on the ground so as to support the support member 2.
[0055] In one embodiment of the utility model, a plurality of universal wheels 6 are provided at the lower end of the base 1, and the plurality of universal wheels 6 are arranged at intervals along the circumference of the base 1. Thus, by providing the plurality of universal wheels 6, the base 1 can be moved along a horizontal plane, thereby facilitating the movement of the antenna testing device 100.
[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
