[0030] Radar is also called "radio positioning", it is the electronic equipment for detecting target by using electromagnetic wave, with the continuous development of modern society, the application of radar is increasing, such as vehicle-mounted radar, image recognition radar and speed radar, etc. These radars are generally fixed on the test pile by clamp during development process to test performance.

[0031] In the process of testing automobile radar, the special working conditions of radar under different fixed angles and different installation heights need to be tested and analyzed in real time, so the position of radar is often changed for multiple tests. In order to improve the test efficiency, a radar clamp with simple structure, convenient disassembly and assembly and flexible switching is urgently needed.

[0032] The main purpose of the utility model is to provide a radar test clamp, which aims to provide a radar test clamp with simple structure, convenient disassembly and assembly and flexible switching.

[0033] Please refer to Figure 1 and Figure 2 The utility model provides a kind of radar test clamp 1000, including moving part 1, clamping part 2 and driving piece 3, the moving part 1 includes first linear guide 11 and second linear guide 12, the second linear guide 12 is movably installed to the first linear guide 11, to be able to move along the extension direction of first linear guide 11, the extension direction of the first linear guide 11 is orthogonal with the extension direction of the second linear guide 12;The clamping part 2 includes mounting seat 21 and two clamping blocks 22, the mounting seat 21 includes first mounting plate 211, the first mounting plate 211 is slidably connected with the second linear guide 12, two clamping blocks 22 are movably installed on the first mounting plate 211 along first direction, to be able to approach or move away from each other, for clamping or loosening radar;The driving piece 3 is used to drive two clamping blocks 22 to approach each other.

[0034] The utility model discloses a technical scheme, through setting up mutually orthogonal first linear guide 11 and second linear guide 12, and with clamping part 2 is located second linear guide 12, makes clamping part 2 can move along two different perpendicular directions, satisfies the demand of position adjustment in radar test process, specifically, through with clamping part 2 setting is two clamping blocks 22, and synchronous setting drive piece 3 drive adds clamping block 22 close, thereby realized the clamping positioning of radar, and the form of two clamping blocks 22 can apply to different size size's radar, and applicability is strong.

[0035] It is worth mentioning that the clamping block 22 is made of plastic or other material with low hardness and good plasticity, which prevents damage to the radar and ensures the electrical performance safety of the clamp due to the good insulation of plastic.

[0036] Further, referring to Figure 2 The mounting seat 21 further includes two second mounting plates 212 oppositely arranged on the first mounting plate 211 in the first direction, the two clamping blocks 22 are arranged between the two second mounting plates 212, and each second mounting plate 212 is provided with a threaded hole; the drive piece 3 includes a screw rod 31, the screw rod 31 passes through the second mounting plate 212 and is threadedly connected with the threaded hole, and the end of the screw rod 31 abuts against the clamping block 22 to drive one of the clamping blocks 22 to move towards the other clamping block 22. In this way, when the radar needs to be clamped, the screw rod 31 is rotated to move in the first direction, thereby pushing the clamping block 22 to clamp the radar, and due to the self-locking feature of the threaded connection, the screw rod 31 will not move easily under small disturbance, thereby achieving positioning effect. When the radar needs to be removed, the screw rod 31 is rotated in the opposite direction to move away from the clamping block 22, thereby canceling the limiting of the clamping block 22. The whole process is simple and convenient to operate, and the efficiency of radar disassembly is improved.

[0037] It should be noted that the scheme does not limit the specific number and installation position of the screw rod 31, and can be arranged on only one side of the first mounting plate 211, and the corresponding first mounting plate 211 on the other side is used to limit the clamping block 22 on the other side, so that only one screw rod 31 needs to be controlled to realize the positioning of the radar. In the preferred embodiment provided by the utility model, the screw rod 31 is provided with two, and is respectively arranged in the threaded hole of the second mounting plate 212. In this way, by synchronously rotating the two screw rods 31, the two clamping blocks 22 can be simultaneously moved towards each other, thereby accelerating the speed of clamping and positioning, improving the working efficiency, and when one of the screw rods 31 is damaged, it can be used as a abutting piece, and only one screw rod 31 needs to be controlled to realize the positioning of the radar, thereby improving the durability of the device.

[0038] It is worth mentioning that the first mounting plate 211 is installed on the second linear guide rail 12 through the flange seat 6, and the structure is more reasonable and convenient to assemble.

[0039] In order to facilitate the operator to rotate the screw rod 31, further, the driving part 3 further comprises a first connecting block 32 and a connecting rod 33, the first connecting block 32 is arranged at the end of the screw rod 31 away from the clamping block 22, and the connecting rod 33 extends in the first direction and is arranged on the first connecting block 32. In this way, by grabbing the connecting rod 33 and rotating it around the axis of the screw rod 31, the clamping block 22 can be controlled to move. It can be understood that the cross section of the connecting rod 33 is much smaller than that of the first connecting block 32, and the distance from the connecting rod 33 and the first connecting block 32 to the axis of the screw rod 31 is 5 to 10 cm, which conforms to the ergonomic design and is convenient for the operator to rotate the connecting rod 33. Compared with directly rotating the screw rod 31 with the palm, shaking the connecting rod 33 is more convenient for human power, and the torque provided is larger, and the clamping force on the radar is also larger.

[0040] It is worth mentioning that the first connecting block 32 is engraved with a pattern on the circumferential surface, which is convenient for the operator to grab and rotate. When the connecting rod 33 is damaged, the screw rod 31 can also be controlled to move by directly rotating the first connecting block 32, so as to clamp or release the radar.

[0041] It is worth mentioning that the first linear guide rail 11 and the second linear guide rail 12 are driven by the screw rod 31 and the rocker in cooperation, which is convenient to operate.

[0042] In order to improve the service life of the clamp, the driving member 3 further comprises a second connecting block 34 arranged at the end of the screw rod 31 close to the clamping block 22 and abutting against the clamping block 22. Since the cross-sectional area of the end of the screw rod 31 is small, the pressure at the abutting position of the screw rod 31 and the clamping block 22 is large, and the second connecting block 34 is arranged to reduce the damage of the screw rod 31 to the clamping block 22 at the abutting position and improve the durability of the clamp. It is worth mentioning that the cross-sectional area of the end of the second connecting block 34 is larger than that of the end of the screw rod 31, and in an embodiment of the present application, the material of the second connecting block 34 is rubber, which further improves the service life of the clamp.

[0043] Further, the outer side of the second connecting block 34 away from the axis of the screw rod 31 is outwardly inclined in the direction close to the clamping block 22. In this way, under the condition of the same volume, the abutting area of the second connecting block 34 and the clamping block 22 is increased, the pressure of the clamping force at the abutting position is reduced, and the durability of the clamp is improved.

[0044] In order to improve the stability of the clamp as a whole, the mounting seat 21 further comprises a plurality of reinforcing ribs 213 arranged on the two opposite sides of the two second mounting plates 212 and connected with the first mounting plate 211. It is worth mentioning that the number of reinforcing ribs 213 is not limited in the present application, and in a specific embodiment, please refer to Figure 2 , the reinforcing ribs 213 are arranged in four and in a triangular shape, two right-angle sides of the triangular shape are connected with the first mounting plate 211 and the second mounting plate 212 respectively, and the reliability of the whole structure is ensured.

[0045] In an embodiment of the present application, the radar test clamp 1000 further comprises a third linear guide rail 4 arranged on the first mounting plate 211, the third linear guide rail 4 extends in the first direction, and the two clamping blocks 22 are respectively slidably connected with the third linear guide rail 4 through two sliding blocks 5. In this way, the clamping blocks 22 can move under the guidance of the guide rail, and the stability of the structure is improved. It is worth mentioning that the clamping blocks 22 are mounted on the sliding blocks 5 through the adapter plate, which is convenient for assembly.

[0046] In an embodiment of the present application, a plurality of grooves 221 of different sizes are arranged on the two opposite sides of the two clamping blocks 22, and the plurality of grooves 221 are used for positioning radars of different sizes. In this way, the clamping blocks 22 can be better applied to radars of different sizes, and the design of the grooves 221 can provide support for the radars in the direction of gravity, prevent the radars from sliding, and improve the reliability of the clamp.

[0047] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
