[0036] Please refer to Figures 1-6 The present application provides a kind of benchmark positioning assembly for antenna test, including platform 1, bottom base 2, flexible sheath 3, elastic displacement assembly 4, suction assembly 5, elastic telescopic assembly 6, rotating part 7, profiling part 8, side positioning assembly 9.

[0037] Further, the platform 1 is used for placing the antenna body, the platform 1 is hollow inside, facilitating the placement of various positioning components, the middle part of the platform 1 is provided with a through slot, the bottom base 2 is arranged along the through slot in the through direction, the top surface of the bottom base 2 abuts against the bottom surface of the antenna, and the bottom base 2 provides a bottom reference for the antenna to limit the position of the bottom surface of the antenna.

[0038] Further, the two sides of the bottom base 2 are respectively hinged with a flexible sheath 3, the lower end of the flexible sheath 3 is rotationally connected with the edge of the bottom base 2, and the upper end of the flexible sheath 3 is close to the top surface of the platform 1, but the height of the upper end will not be higher than the plane of the platform 1.

[0039] The flexible sheath 3 is a flexible structure, which is preferably a flexible rubber that can be flexibly bent, facilitating the adhesion to the curved side surface of the antenna.

[0040] Further, the rubber surface of the flexible sheath 3 close to the antenna is provided with an adsorption component 5, and the other side of the flexible sheath 3 away from the antenna is provided with an elastic displacement component 4.

[0041] When the antenna is placed on the platform 1 for reference positioning, the bottom surface of the antenna is placed on the bottom base 2 to position the bottom surface, and then the elastic displacement component 4 is elastically displaced to drive the connected flexible sheath 3 to approach and adhere to the side surface of the antenna. Since the displacement end of the elastic displacement component 4 is provided with a plurality of elastic members, the flexible sheath 3 is deformed and adheres to the curved side surface of the antenna by different elastic displacement amounts of the plurality of elastic members. Then, the adsorption component 5 on the adhering surface of the antenna adsorbs and fixes the surface of the antenna, and the antenna is fixed on the bottom base 2 by the flexible sheath 3 and the adsorption component 5, and will not be separated.

[0042] Further, the two sides of the bottom base 2 are respectively and symmetrically provided with an elastic expansion component 6, the elastic expansion component 6 is located on the top surface of the platform 1, the expansion direction of the elastic expansion component 6 is towards the top base, the expansion end of the elastic expansion component 6 is provided with a rotating member 7, the rotating member 7 is provided with a profiling member 8, and the profiling end of the profiling member 8 abuts against the side surface of the antenna.

[0043] Preferably, the elastic expansion component 6 will be elastically displaced by the elastic member to drive the rotating member 7 of the expansion end to approach the side surface of the antenna, so that the profiling member 8 on the rotating member 7 abuts against the antenna, the profiling end of the profiling member 8 will follow the different curved side surfaces of the antenna to perform corresponding curved profiling, so as to ensure the clamping of the profiling ends on both sides of the antenna to be more stable and increase the clamping area.

[0044] Preferably, two rotating members 7 are arranged on each elastic stretching component 6, when the elastic stretching component 6 symmetrically clamps the elastic side surface, the four rotating members 7 are on different curved side surfaces in certain cases, when the profiling end is clamped, the rotating member 7 swings according to different curved surfaces, which facilitates the profiling end of the profiling part 8 to abut against the surface with larger curved amplitude. On the other hand, the direction of the clamping force at the clamping position is increased, avoiding the clamping force at the clamping position only directing to one place, which causes the antenna to move under force and affects the reference accuracy.

[0045] Further, the platform 1 is provided with a side surface positioning component 9, the side surface positioning component 9 is provided with two positioning ends, the positioning ends are symmetrically arranged on the side surface of the antenna and abut against the side surface of the antenna, the two positioning components are displaced towards each other by the displacement member, and the side surface of the antenna is hard abutted, avoiding the antenna from being in an inclined state after being clamped by the elastic stretching component 6, thereby ensuring the verticality of the antenna and realizing the side surface reference positioning of the antenna.

[0046] Please refer to Figure 1 and Figure 2 In the embodiment, the elastic displacement component 4 includes a gas cylinder 401, a push rod, and a spring 403.

[0047] Specifically, the gas cylinder 401 is fixed in the hollow interior of the platform 1, a plurality of fixed rods 402 are fixedly arranged on the push rod of the gas cylinder 401, one end of the fixed rod 402 is fixedly connected to one end of the spring 403, and the other end of the spring 403 is fixedly connected to the flexible sheath 3.

[0048] When the push rod of the gas cylinder 401 is extended, the fixed rod 402 is displaced towards the flexible sheath 3, the fixed rod 402 pushes the spring 403, the spring 403 is elastically displaced, and the flexible sheath 3 is elastically acted on, the flexible sheath 3 is close to the antenna on the bottom surface base 2, because the plurality of fixed rods 402 and the spring 403 are arranged, when the flexible sheath 3 contacts the curved side surface of the antenna, the elastic displacement of the spring 403 at different positions is inconsistent, so that the flexible sheath 3 is gradually deformed and is attached to the curved side surface of the antenna.

[0049] Please refer to Figure 1 and Figure 2 In the embodiment, the adsorption component 5 includes a suction cup 501 and a gas pump assembly 502.

[0050] Specifically, the suction cup 501 is fixed on the surface of the flexible cover 3 close to the antenna. When the flexible cover 3 is attached to the surface of the antenna, the suction cup 501 will abut against the surface of the antenna. The suction cup 501 is in communication with the air pump assembly 502 which is fixedly arranged in the interior of the platform 1. The air pump assembly 502 sucks out the air in the suction cup 501 through the air pipe, generates negative pressure, and makes the suction cup 501 adsorb the surface of the antenna, so as to fix the antenna and the flexible cover 3 together and avoid the antenna from separating from the bottom base 2.

[0051] The suction cup 501 is located on the surface of the flexible cover 3 close to the antenna, and the air pipe in communication with the suction cup 501 penetrates through the flexible cover 3 and extends to the interior of the platform 1 from the other surface of the flexible cover 3 and is in communication with the air pump assembly 502. The air pipe is long and curved in the interior of the platform 1. When the flexible cover 3 is deformed to attach to the surface of the antenna, the air pipe will also stretch and displace together with the flexible cover 3.

[0052] In addition, the suction cup 501 corresponds to the spring 1 403 in number. The position of the suction cup 501 on the flexible cover 3 corresponds to the position where the spring 1 403 is connected to the flexible cover 3 (the position where the air pipe penetrates through the flexible cover 3 is located outside the spring 1 403 to avoid interfering with the elastic expansion and contraction of the spring 1 403). Because the connection position of the spring 1 403 is the elastic action point, the surface of the flexible cover 3 at the elastic action point will certainly attach to the surface of the antenna. Therefore, the suction cup 501 at this position will not have the situation that the surface of the suction cup 501 does not completely attach to the surface of the antenna, so that when the air pump assembly 502 sucks air, negative pressure can be generated at the suction cup 501.

[0053] Please refer to Figure 3 and Figure 5 In the embodiment, the elastic expansion and contraction assembly 6 includes a cavity plate 601, an elastic member, and a clamping plate 609.

[0054] Specifically, the elastic member is arranged in the cavity plate 601 and connects the cavity plate 601 and the clamping plate 609. The cavity plate 601 is fixed on the top surface of the platform 1, and the elastic displacement direction of the clamping plate 609 is toward the direction of the bottom base 2 to clamp the antenna on the bottom base 2.

[0055] The elastic member includes a sliding plate 602, a sliding column 603, a spring 2 604, a sliding groove 1 605, a swing plate 606, a sliding groove 2 607, and a spring 3 608.

[0056] Specifically, the inside of the cavity plate 601 is a cavity. The sliding plate 602 is slidingly arranged in the cavity. The two ends of the sliding plate 602 are fixedly provided with the sliding columns 603 which slidingly penetrate through the cavity plate 601. The sliding direction of the sliding plate 602 is toward the direction of the bottom base 2. The spring 2 604 is sleeved on the sliding column 603. The two ends of the spring 2 604 are fixedly connected with the sliding plate 602 and the cavity plate 601 respectively.

[0057] The two ends of the sliding plate 602 are provided with a sliding groove one 605, one end of an oscillating plate 606 is slidingly arranged in the sliding groove one 605, the other end of the oscillating plate 606 is slidingly arranged in a sliding groove two 607, the sliding groove two 607 is arranged at the end of a clamping plate 609, the middle part of the oscillating plate 606 is rotatably arranged on the cavity plate 601.

[0058] When the spring two 604 exerts a spring force on the sliding plate 602, the sliding plate 602 slides to drive one end of the oscillating plate 606 to oscillate, so that the other end of the oscillating plate 606 also oscillates, and the other end of the oscillating plate 606 pushes the clamping plate 609 to displace, so that the clamping plate 609 displaces towards the antenna.

[0059] In addition, the end of the clamping plate 609 is fixedly connected with one end of a spring three 608, the other end of the spring three 608 is fixedly connected with the sliding plate 602, wherein the spring three 608 always pushes the clamping plate 609 to act together with the spring two 604, so that the clamping plate 609 is always in a clamping state.

[0060] In the embodiment, the end of the clamping plate 609 close to the bottom base 2 is also rotatably connected with a rotating part 7, and the rotating part 7 is provided with a profiling part 8.

[0061] The rotating part 7 is a semicircular plate, which is rotatably arranged at the front end of the clamping plate 609, and the front end of the clamping plate 609 is provided with at least two semicircular plate parts.

[0062] The profiling part 8 includes a plurality of contact heads 801 and a spring four 802.

[0063] Specifically, one end of the contact head 801 is slidingly arranged on the rotating part 7, the other end of the contact head 801 abuts against the side surface of the antenna, the sliding end of the contact head 801 is fixedly connected with one end of the spring four 802, and the other end of the spring four 802 is fixedly connected with the rotating part 7.

[0064] A plurality of profiling parts 8 are arranged on the rotating part 7, when the contact head 801 of the profiling part 8 contacts the curved side surface of the antenna, it will elastically displace to different degrees according to different curved side surfaces, so as to realize profiling abutment and clamp the side surface of the antenna.

[0065] Please refer to Figure 3 and Figure 6 In the embodiment, the side surface positioning assembly 9 includes a positioning block 901, a threaded rod 902, and a motor 903.

[0066] Specifically, the positioning block 901 is slidably arranged on the top surface of the platform 1 and in the sliding groove of the clamping plate 609 (the sliding groove is located at the center of the clamping plate 609 and on the symmetry line of the two rotating members 7), the bottom of the positioning block 901 penetrates into the hollow interior of the platform 1, the bottom of the positioning block 901 is threadedly connected with the threaded rod 902, one end of the threaded rod 902 is fixedly connected with the motor 903, and the motor 903 is fixed on the platform 1.

[0067] Each of the two ends of the threaded rod 902 is provided with a thread with opposite screw directions, and each thread is matched with one of the positioning blocks 901.

[0068] Therefore, when the motor 903 drives the threaded rod 902 to rotate, the positioning blocks 901 located on the threads with opposite directions are displaced towards the antenna, so that the positioning blocks 901 abut against and fix the curved side surface of the antenna, because the contact of the positioning blocks 901 is rigid contact, the antenna can be returned to the vertical state in the process of contacting the antenna, and the accuracy of the side positioning reference of the antenna is ensured.
