Wherein, the fixed reference bracket 200 is installed on the base 100 and is disposed perpendicular to the base 100. The two antenna board assemblies 300 are respectively disposed perpendicular to the base 100 and at both sides of the fixed reference support 200, and the two antenna board assemblies 300 are respectively rotatably connected to the fixed reference support 200. The antenna plate assembly 300 includes an antenna plate fixing plate 310 and an antenna plate 320, the antenna plate fixing plate 310 is rotatably connected to the fixed reference frame 200, the antenna plate 320 is mounted in parallel to the antenna plate fixing plate 310 and located on a side of the antenna plate fixing plate 310 away from the fixed reference frame 200, and the antenna plate 320 is movable relative to the antenna plate fixing plate 310, so that a distance between the two antenna plates 320 in the radar antenna testing device 1 can be changed.
Referring to fig. 1 and fig. 2, the base 100 and the fixed reference frame 200 are combined together, in this example, the base 100 is a plate-shaped structure horizontally arranged as shown in the figure; the fixed reference frame 200 is a plate-like structure vertically arranged as a whole, and is mounted on the base 100 and arranged perpendicular to the base 100.
As for the antenna board assembly 300, please refer to fig. 2 specifically, and referring to fig. 1, the two antenna board assemblies 300 are respectively disposed on two sides of the fixed reference support 200 and are perpendicular to the base 100, each antenna board assembly 300 is rotatably mounted on the fixed reference support 200 and is used for mounting the radar antenna board 2, so that a worker can rotate the antenna board assembly 300 until an optimal field angle is reached between the two radar antenna boards 2 when the worker is matched with an external proprietary radar antenna board field angle detection device, and meanwhile, the method for testing the optimal field angle is very simple and convenient, and the worker does not need to continuously hold and rotate the radar antenna board 2 to obtain the optimal field angle.
Specifically, the antenna board assembly 300 includes an antenna board fixing board 310 and an antenna board 320 mounted to the antenna board fixing board 310. The antenna board fixing plate 310 is a plate-shaped structure vertically arranged as shown in the figure, and is integrally vertically arranged above the base 100 and rotatably mounted on the fixed reference support 200, that is: the two antenna board assemblies 300 are rotatably mounted to the base 100 by respective antenna board fixing plates 310. Preferably, the ends of the two antenna board fixing plates 310 rotatably connected to the fixing reference bracket 200 are disposed close to each other, so as to ensure that the distances between the two antenna boards 320 and between the two radar antenna boards 2 do not change much during the rotation of the antenna board fixing plate 310 with respect to the fixing reference bracket 200. Alternatively, the antenna board fixing plate 310 is rotatably connected to the fixed reference frame 200 by hinges 330, the antenna board fixing plate 310 corresponds to one hinge 330, the two hinges 330 are respectively disposed at the edges of the two opposite surfaces of the fixed reference frame 200, and the rotatable portion of the hinge 330 is fixed to the surface of the antenna board fixing plate 310 facing the fixed reference frame 200.
The antenna plate 320 is disposed parallel to the antenna plate fixing plate 310 and located on a side of the antenna plate fixing plate 310 away from the fixed reference frame 200, and is installed on the antenna plate fixing plate 310 and used for fixedly installing the radar antenna plate 2. So, two radar antenna boards 2 set up dorsad at the rotation in-process of antenna board subassembly 300, and then can guarantee that two radar antenna boards 2 are to same side transmission electromagnetic wave relative to antenna board subassembly 300 to guarantee that two radar antenna boards 2's field of view can superpose. The antenna plate 320 can move relative to the antenna plate fixing plate 310, so that the distance between the two antenna plates 320 in the two antenna plate assembly 300 can be changed, and further the distance between the two radar antenna plates 2 can be adjusted to an optimal distance value, so that the signals between the two radar antenna plates 2 do not interfere with each other or the interference value is lower than a set value. In this embodiment, a guide slot 311 extending perpendicularly to the rotation axis O of the antenna board fixing board 310 is disposed on a surface of the antenna board fixing board 310 facing the antenna board 320, a guide block 321 adapted to the guide slot 311 is disposed on a side of the antenna board 320 facing the antenna board fixing board 310, and the guide block 321 is inserted into the guide slot 311, so that the antenna board 320 and the antenna board fixing board 310 are slidably engaged with each other. The staff can make the radar antenna boards 2 installed on the two antenna boards 320 through sliding the antenna board 320 to make the signals not interfere with each other, and the distance between the two antenna boards 320 is as small as possible, on this basis, the angle of the antenna board fixing board 310 is adjusted to make the angle of view formed by the radar antenna boards 2 together the best. By recording the optimal distance between the two antenna boards 320 corresponding to the non-interference between the two radar antenna boards 2 and the included angle between the two antenna boards 320 corresponding to the optimal field angle between the two radar antenna boards 2 (i.e. the included angle between the two antenna board assemblies 300), the relative positions of the two radar antenna boards 2 in the radar can be conveniently installed by the staff in the later period, so that the assembling efficiency of the radar is effectively improved. It should be noted that the above-mentioned process of determining the optimal viewing angle by the external radar antenna panel viewing angle detection device is not a content of the present invention, and will not be described in detail herein.
It should be understood that, even though the guiding slot 311 is disposed on the antenna board fixing plate 310 and the guiding block 321 is disposed on the antenna board 320 in the embodiment, the invention is not limited thereto, as long as the antenna board 320 can move relative to the antenna board fixing plate 310, so that the distance between the two antenna boards 320 can be adjusted; for example, in some other embodiments of the present invention, the guiding groove is disposed on the antenna board 320, and correspondingly, the guiding block is disposed on the antenna board fixing board 310; for another example, in another embodiment of the present invention, the guiding groove is still provided on the antenna board fixing board 310, but it is not provided on the surface facing the antenna board 320, but provided on the top of the antenna board fixing board 310 shown in the figure, and accordingly, the guiding block is provided on the top of the antenna board 320.
Further, the base 100 is further provided with angle scale marks 111, and the angle scale marks 111 are used for assisting in measuring the included angle between the two antenna board assemblies 300, so as to obtain the included angle between the two radar antenna boards 2 respectively mounted on the two antenna board assemblies 300. Specifically, please refer to fig. 3, which shows a schematic projection diagram of the radar antenna testing device 1 in one direction in which the radar antenna boards 2 are installed, the angle scale marks 111 correspond to the antenna board fixing boards 310 one by one, each angle scale mark 111 extends along an arc with the rotation axis O of the corresponding antenna board fixing board 310 as the center, and the two angle scale marks 111 cooperate together to directly measure the included angle between the two antenna board fixing boards 310, so as to determine the included angle between the two radar antenna boards 2. In this embodiment, the angle value of the angle scale mark 111 corresponds to twice the angle between two relatively rotating leaf portions of the hinge 330, and when the two antenna board fixing plates 310 are aligned at the same angle value, the angle value is the angle between the two antenna board assemblies 300, and is also the angle between the two radar antenna boards 2. It should be understood that the angle scale mark 111 is used for directly measuring the angle between the two antenna board assemblies 300 in this embodiment, but in other embodiments of the present invention, the two angle scale marks 111 can also indirectly assist in measuring the angle between the two antenna board assemblies 300; for example, each angle scale mark 111 is used to directly measure the angle value of the antenna board assembly relative to the fixed reference bracket 200, and the worker can determine the angle between the two antenna board assemblies 300 by summing the angle values respectively corresponding to the two antenna board assemblies 300.
Furthermore, in order to fix the radar antenna board 2 relative to the base 100 in the rotation direction after rotating to the desired position along with the antenna board fixing board 310, thereby ensuring that the angle between the two radar antenna boards 2 does not change, facilitating the reading of the angle value, and other subsequent tests, the radar antenna testing device 1 further includes a rotation locking member 400, wherein the antenna board fixing board 310 corresponds to the rotation locking member 400, and the rotation locking member 400 is used for fixing the antenna board fixing board 310 to the base 100 in time; that is, the rotation lock 400 may simultaneously act on the antenna board fixing board 310 and the base 100 to fix the antenna board fixing board 310 to the base 100, or the rotation lock 400 may not simultaneously act on the antenna board fixing board 310 and the base 100 to enable the antenna board fixing board 310 to rotate relative to the base 100. In this embodiment, the rotation locking member 400 includes a first locking screw, which specifically includes a first screw 410 and a first head 420. The first screw 410 penetrates through the base 100 to be in threaded connection with the antenna board fixing board 310, the first head 420 is disposed on a side of the base 100 away from the antenna board fixing board 310, and accordingly, the base 100 is provided with a first avoiding groove 112 for the first screw 410 to penetrate through and for the first screw 410 to move along with the antenna board fixing board 310. When the first locking screw is screwed until the first head 420 abuts against the base, the antenna board fixing plate 310 is fixed with the base 100; when the first locking screw is screwed until the first head 420 is separated from the base 100, the antenna board fixing plate 310 may rotate relative to the base 100. Optionally, the first avoiding groove 112 is arc-shaped, and a center of the first avoiding groove 112 falls on the rotation axis O of the antenna board fixing board 310 corresponding thereto; it is understood that in other embodiments of the present invention, the first avoiding groove 112 may have other shapes, but it is ensured that the first head 420 of the first locking screw cannot pass through the first avoiding groove along the direction parallel to the rotation axis O, specifically, the first head 420 may be sized to be larger than the width of the first avoiding groove 112, or a spacer having a diameter larger than the width of the first avoiding groove 112 may be disposed between the first head 420 and the base 100. Preferably, the bottom of the antenna board fixing plate 310 is attached to the surface of the base 100 facing the antenna board fixing plate 310, that is, there is no gap between the two; therefore, on one hand, the base 100 can support the antenna board fixing plate 310, so that the phenomenon that the hinge 330 has an influence on the service life due to too large torque is avoided, and on the other hand, the defect that the antenna board fixing plate 310 and/or the hinge 330 is damaged because the antenna board fixing plate 310 is continuously close to the base 100 in the locking process of the first locking screw can also be avoided. Of course, in other embodiments of the present invention, the rotation locking member 400 may also have other structures, such as a bolt and a nut, a magnet, a hook and loop fastener, etc., which are not limited to one another, as long as it can be used to fix the antenna board fixing plate 310 and the base 100.
Similarly, for conveniently recording the optimal distance between the two radar antenna boards 2 when the signals do not interfere with each other, the antenna board fixing board 310 is further provided with a length scale mark (not shown in the figure) on the surface facing the antenna board 320, and the extending direction of the length scale mark is parallel to the guide slot 311, so as to assist in measuring the parallel and level of the two antenna boards 320, that is, the distance between the two antenna boards 320 and the same plane when the two antenna boards 320 fall on the same plane. For example, when the user moves the antenna plate 320 to make the signals of the two radar antenna plates 2 not interfere with each other or the interference degree is lower than the set value, the user can record the distance value through the length scale mark; then, the user can separate this distance value with two radar antenna boards 2 earlier at the in-process of assembling the radar to relative rotation makes the contained angle between two radar antenna boards 2 until the contained angle value that best angle of view corresponds, and the mounting structure of radar antenna board 2 can be according to above-mentioned distance value and contained angle value adaptation design, further makes things convenient for the equipment of radar.
Further, in order to fix the radar antenna board 2 relative to the base 100 in the extending direction of the guide slot 311 after the radar antenna board 2 slides to a desired position along with the antenna board 320, so as to ensure that the distance between the two radar antenna boards 2 is kept stable and does not change, thereby facilitating a worker to test the optimal angle of view between the two radar antenna boards 2 on the basis, or other subsequent tests, the radar antenna testing device 1 further includes a sliding lock member 500, wherein the antenna board 320 corresponds to the sliding lock member 500, and the sliding lock member 500 is used for fixing the antenna board 320 to the antenna board fixing plate 310 in time; that is, the sliding lock 500 may simultaneously act on the antenna board 320 and the antenna board fixing board 310 to fix the antenna board 320 to the antenna board fixing board 310, or the sliding lock 500 may not simultaneously act on the antenna board 320 and the antenna board fixing board 310 to enable the antenna board 320 to slide relative to the antenna board fixing board 310. Referring to fig. 2 in combination with other figures, in the embodiment, the sliding locking member 500 includes a second locking screw, which specifically includes a second screw 510 and a second head 520. The second screw 510 penetrates through the antenna board fixing plate 310 to be in threaded connection with the antenna board 320, the second head 520 is disposed on a side of the antenna board fixing plate 310 away from the antenna board 320, and accordingly, a second avoiding groove 312 is formed in the antenna board fixing plate 310, through which the second screw 510 penetrates and which allows the second screw 510 to move together with the antenna board 320. When the second locking screw is screwed until the second head 520 abuts against one side of the antenna plate fixing plate 310 away from the antenna plate 320, the antenna plate 320 is fixed with the antenna plate fixing plate 310; when the second locking screw is screwed to separate the second head 520 from the side of the antenna board fixing board 310 away from the antenna board 320, the antenna board 320 can drive the radar antenna board 2 mounted thereon to move together relative to the antenna board fixing board 310, thereby facilitating the testing of the distance between the radar antenna board 2 and the antenna board fixing board 310 without interference. Alternatively, the second avoiding groove 312 is linear and is disposed parallel to the guide groove 311; it is understood that, in other embodiments of the present invention, the second avoiding groove 312 may have other shapes, but it should be ensured that the second head 520 of the second locking screw cannot pass through the second avoiding groove 312 in the direction perpendicular to the antenna plate 310, specifically, the second head 520 may be sized to be larger than the width of the second avoiding groove 312, or a spacer having a diameter larger than the width of the second avoiding groove 312 may be disposed between the second head 520 and the antenna plate 310. Optionally, an antenna board fixing plate 310 corresponds to two second locking screws, and accordingly, the same antenna board fixing plate 310 is provided with two second avoiding grooves 312, and the two second avoiding grooves 312 are respectively disposed on two sides of the guide groove 311. Of course, in other embodiments of the present invention, the sliding locking member 500 may also have other structures, such as a bolt and a nut, a magnet, a hook and loop fastener, etc., which are not limited herein, as long as it can be used to fix the antenna board 320 and the antenna board fixing board 310.
It is worth mentioning that the invention does not limit the sequence of the best angle of view and the best distance of the radar antenna plate 2, the worker can test the best angle of view of the radar antenna plate 2 first and then the best distance of the radar antenna plate 2 by the radar antenna testing device 1; it is also possible to test the optimal distance of the radar antenna board 2 first, and then test the optimal angle of view of the radar antenna board 2.
The radar antenna testing device provided by the embodiment of the invention comprises a base 100, a fixed reference support 200 and a two-antenna-board assembly 300.
