[0033] EMBODIMENT

[0034] Please refer to Figures 1-6The utility model provides a profile support seat for antenna test, including base 1, air bag assembly 2, air pump assembly 3, sliding plate 4, elastic film 5, pressure relief assembly 6.

[0035] Further, the support surface of the base 1 is provided with a receiving groove, and a plurality of sliding grooves are arranged in the receiving groove. Each sliding groove is vertically slidably provided with a sliding plate 4. The sliding plate 4 only moves vertically through the sliding groove.

[0036] The plurality of sliding plates 4 are uniformly arranged in the receiving groove. The top end surface of the sliding plate 4 abuts against the surface of the antenna to be tested, thereby supporting the antenna.

[0037] Further, the air bag assembly 2 is arranged between the sliding plate 4 and the base 1. The air bag assembly 2 provides elastic force for the sliding plate 4, thereby facilitating the elastic sliding of the sliding plate 4 and the profile contact with the surface of the antenna.

[0038] For reference Figure 3 In this embodiment, the air bag assembly 2 includes a main air bag 201 and a sub air bag 202.

[0039] Specifically, the main air bag 201 is installed between the bottom end of the sliding plate 4 and the bottom surface of the receiving groove and is fixed in the receiving groove. The outer wall of the main air bag 201 abuts against the bottom end of the sliding plate 4. When the main air bag 201 is inflated and expanded or deflated and contracted, the sliding plate 4 also vertically slides upward or downward accordingly.

[0040] Preferably, when the special-shaped surface of the antenna is placed on the top end of the plurality of sliding plates 4, the sliding plate 4 starts to move downward under the gravity of the antenna and presses the main air bag 201 below. The main air bag 201 is squeezed, the volume is reduced, the gas space pressure in the main air bag 201 is increased, and the gas pressure generated by elastic deformation is used to offset the gravity of the antenna, so that the sliding plate 4 no longer slides, thereby achieving support. Since the surface of the antenna is a special-shaped structure (such as a stepped structure or a curved surface structure), the downward displacement depth of the sliding plate 4 located at different positions of the antenna is not consistent, thereby achieving profile support of the special-shaped surface of the antenna by the plurality of separated sliding plates 4.

[0041] In addition, the adjacent sliding plates 4 are not in contact and have a gap space. Each gap space is correspondingly provided with a sub air bag 202. Each sub air bag 202 is in communication with the gas space of the main air bag 201. When the main air bag 201 is squeezed to generate gas pressure, the sub air bag 202 also generates corresponding gas pressure. The top end of the sub air bag 202 is attached to the top end side wall of the sliding plate 4.

[0042] The top of the gap space is further provided with an elastic film 5. The film surface of the elastic film 5 abuts against the top end of the sub air bag 202. The elastic film 5 is an elastic rubber structure. The two ends of the elastic film 5 are fixedly connected to the top end of the adjacent sliding plate 4.

[0043] Although the antenna surface is profiled and supported by several slide plates 4, a step structure is formed between the adjacent slide plates 4 during the supporting process due to the different sliding depths of the profiled slide plates 4, and the profiled effect is poor.

[0044] Preferably, when the adjacent slide plates 4 slide at different depths and the heights of the top ends of the slide plates 4 are inconsistent, the elastic film 5 connected between the two slide plates 4 will use the elastic extension performance of the elastic rubber structure of the elastic film 5 to make the step surface formed between the two slide plates 4 become a slope (the slope surface is the film surface of the elastic film 5), and the sub-air bag 202 in the gap space will be extruded and deformed by the gas pressure from the main air bag 201 during the supporting process of the slide plates 4, so that the top end of the sub-air bag 202 extrudes the film surface of the elastic film 5, the top end of the sub-air bag 202 drives the film surface to contact and fit the profiled surface of the antenna, and the top end of the sub-air bag 202 will be deformed under the interaction of the gas pressure and the gravity of the antenna, so that the film surface of the elastic film 5 is deformed, and the film surface gradually profiled and fitted the antenna surface from the slope, so that the gap space between the adjacent slide plates 4 also profiled and supports the antenna surface.

[0045] Further, the main air bag 201 is connected with a gas pump assembly 3 at one end, which is responsible for air supplement of the air bag assembly 2.

[0046] Please refer to Figures 3-4 In the embodiment, the gas pump assembly 3 includes a gas pump 301 and a pressure valve two 602.

[0047] Specifically, the pump gas pipe of the gas pump 301 communicates with the gas space of the main air bag 201, the gas pump 301 is fixed outside the base 1, and the pressure valve one 302 is fixedly arranged between the pump gas pipe and the gas space.

[0048] The pressure valve one 302 is provided with a gas pressure sensor, and when the gas pressure sensor senses that the gas pressure reaches a sensing threshold value, the pressure valve one 302 is opened.

[0049] Therefore, when the gas pump 301 pumps the air bag assembly 2, the gas pressure in the pump gas pipe will gradually be greater than or equal to the threshold value, so that the pressure valve one 302 is opened, the pump gas pipe is communicated with the gas space of the main air bag 201, and the air supplement is performed.

[0050] Further, the main air bag 201 is connected with a gas pump assembly 3 at one end, which is responsible for air supplement of the air bag assembly 2.

[0051] Please refer to Figure 3 In the embodiment, the gas pump assembly 3 includes a gas pump 301 and a pressure valve two 602.

[0052] Specifically, the gas space of the main air bag 201 is communicated with the pressure relief cavity 601, the pressure relief cavity 601 is fixed outside the base 1, and the pressure valve two 602 is fixed between the gas space and the pressure relief cavity 601.

[0053] The pressure valve two 602 is provided with an air pressure sensor, when the air pressure sensor senses that the air pressure reaches a sensing threshold value, the pressure valve two 602 is opened, and when the air pressure sensor senses that the air pressure does not reach the sensing threshold value, the pressure valve two 602 is closed.

[0054] It is worth noting that the pressure valve is the basic common sense that can be mastered by those skilled in the art, so it is not described in detail in the specification.

[0055] When the antenna weight is light, the air pressure generated by the extrusion in the gas space is less than the threshold value, the pressure valve two 602 is closed, the gas space is not communicated with the pressure relief cavity 601, and the pressure relief work is not performed.

[0056] When the antenna weight is heavy, the air pressure generated by the extrusion in the gas space is greater than or equal to the threshold value, the pressure valve two 602 is opened, the gas space is communicated with the pressure relief cavity 601, a part of the gas in the gas space is discharged, and the pressure relief work is performed on the gas space; when the air pressure is less than the threshold value in the process of discharging the gas, the pressure valve two 602 is closed.

[0057] So far, the embodiments of the utility model have been described in detail. In order to avoid shielding the concept of the utility model, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions of the utility model herein according to the above description, and the scope of the utility model is limited by the appended claims.
