Description

[Technical field]

[0001] The embodiments of the present invention relate to the field of radar technology, and in particular to a radar antenna testing device. [Background technology]

[0002] The Advanced Driving Assistance System (ADAS) uses various sensors installed in the car, such as radars and cameras, to sense the surrounding environment at any time while the car is driving, so that the driver can be aware of possible dangers in advance, thereby effectively increasing the comfort and safety of car driving.

[0003] Among them, the vehicle-mounted radar generally includes a radar antenna board, through which the vehicle-mounted radar transmits electromagnetic waves outward and receives reflected electromagnetic waves; however, the field of view of a vehicle-mounted radar with only one radar antenna board is less than 180 degrees, and its detection range is relatively small. In order to overcome the above shortcomings, some manufacturers' vehicle-mounted radars on the market currently include a base and two radar antenna boards installed on the base. The two radar antenna boards are relatively inclined, which allows the outer edges of the overall field of view of the two radar antenna boards to expand outward, thereby increasing the field of view of the vehicle-mounted radar.

[0004] The inventors of the present invention discovered during the process of implementing the present invention that in order to obtain the optimal field of view angle between the two radar antenna boards, the industry currently mainly adopts manual adjustment of the angle between the two radar antenna boards, and cooperates with external proprietary field of view angle detection equipment to test the optimal field of view angle. However, handheld radar antenna boards have uncertain factors such as easy shaking, and this method is less efficient in obtaining the optimal field of view angle. [Summary of the invention]

[0045] See also Figure 1 and Figure 2 , which respectively show a three-dimensional schematic diagram and an exploded schematic diagram of a radar antenna test device 1 provided by one embodiment of the present invention, in which a radar antenna board 2 is installed. The radar antenna test device includes a base 100, a fixed reference bracket 200 and two antenna board assemblies 300. Among them, the fixed reference bracket 200 is installed on the base 100 and is vertically arranged with the base 100. The two antenna board assemblies 300 are respectively arranged vertically with the base 100 and are respectively arranged on both sides of the fixed reference bracket 200. The two antenna board assemblies 300 are respectively rotatably connected with the fixed reference bracket 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 above-mentioned fixed reference bracket 200. The antenna plate 320 is installed in parallel to the antenna plate fixing plate 310 and is located on the side of the antenna plate fixing plate 310 away from the above-mentioned fixed reference bracket 200. 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 radar antenna test device 1 can be changed.

[0046] For the above base 100 and fixed reference bracket 200, please combine Figure 1 and Figure 2 In this example, the base 100 as a whole is a plate-like structure arranged horizontally as shown in the figure; the fixed reference bracket 200 as a whole is a plate-like structure arranged vertically as shown in the figure, which is installed on the base 100 and arranged perpendicularly to the base 100.

[0047] For the above antenna board assembly 300, please refer to Figure 2 , while combining Figure 1The two antenna panel assemblies 300 are respectively arranged on both sides of the fixed reference bracket 200 and are arranged vertically with the base 100. Each antenna panel assembly 300 can be rotatably installed on the fixed reference bracket 200 and is used to install the radar antenna panel 2, so that the staff can cooperate with the external proprietary radar antenna panel field of view angle detection equipment by simply rotating the antenna panel assembly 300 until the best field of view angle is reached between the two radar antenna panels 2. At the same time, the method of testing the best field of view angle is extremely simple, and the staff does not need to continuously hold and rotate the radar antenna panel 2 to obtain the best field of view angle.

[0048] Specifically, the antenna panel assembly 300 includes an antenna panel fixing plate 310 and an antenna panel 320 mounted on the antenna panel fixing plate 310. The antenna panel fixing plate 310 is a plate-shaped structure arranged vertically as shown in the figure, which is arranged vertically above the base 100 as a whole and is rotatably mounted on the fixed reference bracket 200, that is, the two antenna panel assemblies 300 are rotatably mounted on the base 100 through their respective antenna panel fixing plates 310. Preferably, the ends of the two antenna panel fixing plates 310 that are rotatably connected to the fixed reference bracket 200 are arranged close to each other, so as to better ensure that the distance between the two antenna panels 320 and the distance between the two radar antenna panels 2 do not change much during the rotation of the antenna panel fixing plate 310 relative to the fixed reference bracket 200. Optionally, the antenna plate fixing plate 310 is rotatably connected to the fixed reference bracket 200 via a hinge 330, one antenna plate fixing plate 310 corresponds to one hinge 330, and the two hinges 330 are respectively arranged on the edges of the two opposite surfaces of the fixed reference bracket 200, and the rotatable part of the hinge 330 is fixed to the side of the antenna plate fixing plate 310 facing the fixed reference bracket 200.

[0049] The antenna plate 320 is arranged parallel to the antenna plate fixing plate 310 and is located on the side of the antenna plate fixing plate 310 away from the fixed reference bracket 200. It is installed on the antenna plate fixing plate 310 and is used to fix the radar antenna plate 2. In this way, the two radar antenna plates 2 are arranged back to back during the rotation of the antenna plate assembly 300, thereby ensuring that the two radar antenna plates 2 emit electromagnetic waves to the same side relative to the antenna plate assembly 300, thereby ensuring that the fields of view of the two radar antenna plates 2 can be superimposed. 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 assemblies 300 can change, and then the distance between the two radar antenna plates 2 can be adjusted to the 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 the set value. In this embodiment, a guide groove 311 extending perpendicularly to the rotation axis O of the antenna plate fixing plate 310 is provided on one side of the antenna plate fixing plate 310 facing the antenna plate 320, and a guide block 321 matching the guide groove 311 is provided on one side of the antenna plate 320 facing the antenna plate fixing plate 310, and the guide block 321 is inserted into the guide groove 311 so that the antenna plate 320 and the antenna plate fixing plate 310 can slide and cooperate. The staff can slide the antenna plate 320 so that the signals of the radar antenna plates 2 respectively installed on the two antenna plates 320 do not interfere with each other, and the distance between the two antenna plates 320 is as small as possible. On this basis, the angle of the antenna plate fixing plate 310 is adjusted to optimize the viewing angle formed by each radar antenna plate 2. 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 angle between the two antenna boards 320 corresponding to the optimal field of view between the two radar antenna boards 2 (also the angle between the two antenna board assemblies 300), it is convenient for the staff to install the relative positions of the two radar antenna boards 2 in the radar later, so as to effectively improve the assembly efficiency of the radar. It is worth mentioning that the above process of determining the optimal field of view angle by using an external radar antenna board field of view angle detection device is not the content of the present invention and will not be described in detail here.

[0050] It can be understood that even though in the present embodiment, the guide groove 311 is provided on the antenna plate fixing plate 310 and the guide block 321 is provided on the antenna plate 320, the present invention is not limited thereto, as long as it is ensured that the antenna plate 320 can be moved relative to the antenna plate fixing plate 310 so that the distance between the two antenna plates 320 can be adjusted; for example, in some other embodiments of the present invention, the above-mentioned guide groove is provided on the antenna plate 320, and correspondingly, the guide block is provided on the antenna plate fixing plate 310; for another example, in some other embodiments of the present invention, the above-mentioned guide groove is still provided on the antenna plate fixing plate 310, but it is not provided on the side facing the antenna plate 320, but is provided on the top of the antenna plate fixing plate 310 shown in the figure, and correspondingly, the guide block is provided on the top of the antenna plate 320.

[0051] Furthermore, the base 100 is also provided with an angle scale mark 111, which is used to assist in measuring the angle between the two antenna panel assemblies 300, and then the angle between the two radar antenna panels 2 respectively installed on the two antenna panel assemblies 300 can be obtained. Figure 3 , which shows a schematic projection diagram of a direction in which the radar antenna test device 1 is installed with a radar antenna board 2, wherein the angle scale mark 111 corresponds to the antenna board fixing plate 310 one by one, and each angle scale mark 111 extends along an arc with the rotation axis O of the corresponding antenna board fixing plate 310 as the center, and the two angle scale marks 111 cooperate to directly measure the angle between the two antenna board fixing plates 310, and then determine the 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 the two relatively rotating leaf parts in the hinge 330, so when the angle value of the alignment of the two antenna board fixing plates 310 is the same, the angle value is the angle between the two antenna board assemblies 300, and also the angle between the two radar antenna boards 2. It should be understood that in the present embodiment, the angle scale mark 111 is used to directly measure the angle between the two antenna panel assemblies 300, 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 panel assemblies 300; for example, each angle scale mark 111 is used to directly measure the angle value of the antenna panel assembly relative to the fixed reference bracket 200, and the staff can determine the angle between the two antenna panel assemblies 300 by adding the angle values ​​corresponding to the two antenna panel assemblies 300.

[0052] Furthermore, in order to make the radar antenna plate 2 rotate to the desired position with the antenna plate fixing plate 310, it can be fixed relative to the base 100 in the rotation direction, thereby ensuring that the angle between the two radar antenna plates 2 does not change, facilitating the reading of the angle value and subsequent other tests, the radar antenna test device 1 also includes a rotation locking member 400, one antenna plate fixing plate 310 corresponds to a rotation locking member 400, and the rotation locking member 400 is used to timely fix the antenna plate fixing plate 310 to the base 100; that is, the rotation locking member 400 can act on the antenna plate fixing plate 310 and the base 100 at the same time to fix the antenna plate fixing plate 310 to the base 100, and the rotation locking member 400 can also act on the antenna plate fixing plate 310 and the base 100 at different times, so that the antenna plate fixing plate 310 can rotate relative to the base 100. In this embodiment, the rotation locking member 400 includes a first locking screw, and the first locking screw specifically includes a first screw 410 and a first head 420. The first screw rod 410 passes through the base 100 and is threadedly connected with the antenna plate fixing plate 310. The first head 420 is provided on the side of the base 100 away from the antenna plate fixing plate 310. Accordingly, the base 100 is provided with a first avoidance groove 112 for the first screw rod 410 to pass through and for the first screw rod 410 to move with the antenna plate fixing plate 310. When the first locking screw is screwed until the first head 420 abuts against the base, the antenna plate fixing plate 310 is fixed to the base 100; when the first locking screw is screwed until the first head 420 is separated from the base 100, the antenna plate fixing plate 310 can rotate relative to the base 100. Optionally, the above-mentioned first avoidance groove 112 is arc-shaped, and the center of the first avoidance groove 112 falls on the rotation axis O of the corresponding antenna board fixing plate 310; it can be understood that in other embodiments of the present invention, the first avoidance groove 112 can also be other shapes, but it should be ensured that the first head 420 of the first locking screw cannot pass through the first avoidance groove in a direction parallel to the above-mentioned rotation axis O. Specifically, the size of the first head 420 can be designed to be larger than the width of the first avoidance groove 112, or a gasket with a diameter larger than the width of the first avoidance groove 112 can be set between the first head 420 and the base 100. Preferably, the bottom of the antenna plate fixing plate 310 is arranged to fit with the side of the base 100 facing the antenna plate fixing plate 310, that is, there is no gap between the two; in this way, on the one hand, the base 100 can support the antenna plate fixing plate 310, preventing the hinge 330 from being affected by excessive torque, and on the other hand, it can also prevent the antenna plate fixing plate 310 from constantly approaching the base 100 during the process of being locked by the first locking screw, thereby causing the antenna plate fixing plate 310 and / or the hinge 330 to be damaged. Of course, in other embodiments of the present invention, the rotation locking member 400 can also be other structures, such as bolts and nuts, magnets, Velcro, etc., which are not limited here one by one, as long as they can be used to fix the antenna plate fixing plate 310 to the base 100.

[0053] Similarly, in order to facilitate recording the optimal distance between the two radar antenna panels 2 when the signals do not interfere with each other, the antenna panel fixing plate 310 is also provided with a length scale mark (not shown in the figure) on the side facing the antenna panel 320. The extension direction of the length scale mark is parallel to the guide groove 311, and is used to assist in measuring the alignment of the two antenna panels 320, that is, the distance between the two antenna panels 320 when the two antenna panels 320 fall on the same plane. For example, when the user moves the antenna panel 320 so that the signals of the two radar antenna panels 2 do not interfere with each other or the interference level is lower than the set value, the user can record the distance value through the length scale mark; then, during the process of assembling the radar, the user can first separate the two radar antenna panels 2 by the distance value, and relatively rotate them until the angle between the two radar antenna panels 2 is the angle value corresponding to the optimal field of view angle. The installation structure of the radar antenna panel 2 can be adaptively designed according to the above distance value and angle value, which further facilitates the assembly of the radar.

[0054] Furthermore, in order to allow the radar antenna plate 2 to slide to the desired position along with the antenna plate 320, it can be fixed relative to the base 100 in the direction in which the guide groove 311 extends, so as to ensure that the distance between the two radar antenna plates 2 remains stable and does not change, thereby facilitating the staff to test the optimal field of view between the two radar antenna plates 2 on this basis, or other subsequent tests, the radar antenna test device 1 also includes a sliding locking member 500, one antenna plate 320 corresponds to one sliding locking member 500, and the sliding locking member 500 is used to fix the antenna plate 320 to the antenna plate fixing plate 310 in a timely manner; that is, the sliding locking member 500 can act on the antenna plate 320 and the antenna plate fixing plate 310 at the same time to fix the antenna plate 320 to the antenna plate fixing plate 310, and the sliding locking member 500 can also act on the antenna plate 320 and the antenna plate fixing plate 310 at different times, so that the antenna plate 320 can slide relative to the antenna plate fixing plate 310. Please refer to Figure 2In combination with other drawings, in this embodiment, the sliding locking member 500 includes a second locking screw, which specifically includes a second screw rod 510 and a second head 520. The second screw rod 510 passes through the antenna plate fixing plate 310 and is threadedly connected to the antenna plate 320. The second head 520 is arranged on the side of the antenna plate fixing plate 310 away from the antenna plate 320. Accordingly, the antenna plate fixing plate 310 is provided with a second avoidance groove 312 for the second screw rod 510 to pass through and for the second screw rod 510 to move with the antenna plate 320. When the second locking screw is screwed until the second head 520 abuts against the side of the antenna board fixing plate 310 facing away from the antenna board 320, the antenna board 320 is fixed to the antenna board fixing plate 310; when the second locking screw is screwed until the second head 520 separates from the side of the antenna board fixing plate 310 facing away from the antenna board 320, the antenna board 320 can drive the radar antenna board 2 installed thereon to move relative to the antenna board fixing plate 310, thereby facilitating the testing of the distance at which the radar antenna boards 2 do not interfere with each other. Optionally, the second avoidance groove 312 is in a straight line and is arranged parallel to the guide groove 311; it is understandable that in other embodiments of the present invention, the second avoidance groove 312 may also be in other shapes, but it should be ensured that the second head 520 of the second locking screw cannot pass through the second avoidance groove 312 in a direction perpendicular to the antenna plate 310. Specifically, the size of the second head 520 may be designed to be larger than the width of the second avoidance groove 312, or a gasket having a diameter larger than the width of the second avoidance groove 312 may be arranged between the second head 520 and the antenna plate 310. Optionally, one antenna plate fixing plate 310 corresponds to two second locking screws, and accordingly, the same antenna plate fixing plate 310 is provided with two second avoidance grooves 312, which are respectively arranged on both sides of the guide groove 311. Of course, in other embodiments of the present invention, the sliding locking member 500 may also be other structures, such as bolts and nuts, magnets, Velcro, etc., which are not limited here one by one, as long as they can be used to fix the antenna plate 320 to the antenna plate fixing plate 310.

[0055] It is worth mentioning that the present invention does not limit the order of testing the optimal field of view angle and the optimal distance of the radar antenna board 2. The staff can first test the optimal field of view angle of the radar antenna board 2 and then test the optimal distance of the radar antenna board 2 through the radar antenna testing device 1; or the staff can first test the optimal distance of the radar antenna board 2 and then test the optimal field of view angle of the radar antenna board 2.

[0056] The radar antenna test device provided by the embodiment of the present invention includes a base 100, a fixed reference bracket 200 and two antenna plate assemblies 300. Among them, the fixed reference bracket 200 is installed on the base 100 and is arranged vertically with the base 100. The two antenna plate assemblies 300 are respectively arranged vertically with the base 100, and are respectively arranged on both sides of the fixed reference bracket 200. The two antenna plate assemblies 300 are respectively connected to the fixed reference bracket 200 rotatably. 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 bracket 200. The antenna plate 320 is installed in parallel with the antenna plate fixing plate 310 and is located on the side of the antenna plate fixing plate 310 away from the fixed reference bracket 200. The antenna plate 320 can move relative to the antenna plate fixing plate 310 so that the distance between the two antenna plates 320 can change.

[0057] The radar antenna test device 1 provided in the embodiment of the present invention can be installed on the antenna plate 320 by the radar antenna plate 2. Then the staff only needs to rotate the antenna plate fixing plate 310 to adjust the angle between the two radar antenna plates 2 until the angle between the two radar antenna plates 2 reaches the optimal field of view, without the need to hold the radar antenna plate 2 for adjustment. This can avoid uncertain factors such as easy shaking caused by holding the radar antenna plate 2. The radar antenna test device 1 can improve the efficiency of testing the optimal field of view. In addition, the staff can also adjust the two radar antenna plates to the optimal distance by moving the antenna plate.
