[0017] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0018] In the following description, the example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0019] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0020] In order to solve the above technical problems, this application provides a terminal wireless charging near-field radiation detection system, please refer to the attached Figure 1 To Attachment Figure 6 , including a sample table 1, a mobile device 2 and an arm 3, wherein the top surface of the sample table 1 is used to fix the electronic terminal 11 in the wireless charging state, and the top surface of the sample table 1 forms a detection space; the mobile device 2 is placed adjacent to the fixed table; one end of the arm 3 is provided with a detection head 4 accommodated in the detection space, and the other end is connected to the mobile device 2; it also includes a main control box, which is placed at the lower part of the mobile device 2, and the main control box is equipped with a main control board connected to an external host computer, the main control board controls the movement of the mobile device 2, and the outer wall of the main control box is also provided with at least one cooling fan to dissipate the heat of the main control board in the box; In the specific use process of the present application: first, the electronic terminal 11 is connected to the wireless charger so that the electronic terminal 11 is in a charging state, and then the electronic terminal 11 in a charging state is fixed on the sample table 1; the mobile device 2 is electrically connected to the main control box, and after the main control box is connected to the host computer, the detection space is constructed through the host computer, and the corresponding azimuth coordinates are input, and the mobile device 2 moves the detection head 4 to the corresponding coordinate position to collect the radiation intensity of the near-field electric field and the near-field electromagnetic field at the coordinate position; It can be seen that, through the cooperation of the moving device 2 and the supporting arm 3, the detection head 4 can be moved to any position in the detection space and remain stationary, without the need for manual measurement. The obtained orientation accuracy is better and the data is more accurate.

[0021] In this embodiment, the table top of the sample table 1 is also provided with a clamping structure 12, and the clamping structure 12 is used to make the charging contact surface of the electronic terminal 11 perpendicular to the table top of the sample table 1. It is not difficult to understand that in actual use, when the user puts the electronic terminal 11 in a charging state close to the ear for use, the near-field radiation formed has a greater potential impact on the human body. Therefore, by placing the electronic terminal 11 upright on the table top through the clamping structure 12, it can better simulate the above-mentioned usage scenario to obtain radiation data with more reference value.

[0022] The mobile device 2 can use a robotic arm or a three-axis mechanism 22 to realize the movement of the detection head 4. In a preferred solution, the mobile device 2 includes a box 21 and a three-axis mechanism 22 located in the box 21. The box 21 faces the opening of the detection space, and the support arm 3 is connected to the three-axis mechanism 22 through the opening; the three-axis mechanism 22 has a lower manufacturing cost than the robotic arm, and can achieve precise positioning through different high-precision motors.

[0023] In the specific scheme, the three-axis mechanism 22 is composed of a first screw rod unit 221, a second screw rod unit 222 and a third screw rod unit 223. The two first screw rod structures are respectively placed on two opposite side walls of the box body 21, and the two ends of the second screw rod unit 222 are respectively connected to the first moving parts of the two first screw rods; the third screw rod unit 223 is fixed on the second moving part of the second screw rod; the support arm 3 is fixedly connected to the third moving part of the third screw rod unit 223; the three moving directions formed by the first moving part, the second moving part and the third moving part are perpendicular to each other; it is not difficult to understand that by reciprocating the first moving part, the second moving part and the third moving part, the support arm 3 can be flexibly driven to operate flexibly, so that the detection head 4 can be accurately stopped at any position in the detection space.

[0024] In this embodiment, the three-axis mechanism 22 also includes a first guide rail 23, and two groups of first guide rails 23 are respectively placed on two opposite side walls of the box body 21, and are located on both sides of the first screw rod unit 221 on the same side; there is also a second guide rail 24 between the two first guide rails 23 at the same end, and the two second guide rails 24 are respectively placed on both sides of the second guide rail 24; the two ends of the third screw rod unit 223 are respectively connected to the second guide rail 24; it is not difficult to understand that the first guide rail 23, the second guide rail 24 and the third guide rail of the channel can make the first moving part, the second moving part and the third moving part smoother during reciprocating motion, and the movement route is also more unified and accurate.

[0025] In a more optimal solution, the first guide rail 23 and the second guide rail 24 are connected by an angle iron piece 25; the angle iron piece 25 can connect the first guide rail 23 and the second guide rail 24 together, enhance the integrity of the overall mobile device 2, and can effectively increase the overall strength of the mobile device 2.

[0026] In this embodiment, the driving rod motors of the first screw unit 221, the second screw unit 222 and the third screw unit 223 are all servo motors; in actual applications, the host computer can control the speed and period of any servo motor through the main control board, and then accurately control the position detection position of the detection head 4.

[0027] In this embodiment, the support arm 3 is provided with a mounting plate 31, and a first clamp 32 and a second clamp 33 are provided on a side of the mounting plate 31 close to the sample stage 1, and the first clamp 32 and the second clamp 33 are provided with a gap for the working end of the detection head 4 to protrude; it is not difficult to understand that technicians can quickly remove and support the mounting plate 31 through the first clamp 32 and the second clamp 33, and the avoidance gap formed between the first clamp 32 and the second clamp 33 can support detection heads 4 of various specifications.

[0028] It is found in actual use that when the spatial activity parameters of the measuring point are large, the detection head 4 may become loose locally, causing the working end of the detection head 4 to tilt, which ultimately affects the detection structure. Therefore, in this embodiment, the mounting plate 31 also includes a first fixed protrusion 34 and a second fixed protrusion 35 spaced apart, and the first clamp 32, the second clamp 33, the first fixed protrusion 34 and the second fixed protrusion are enclosed to form a mounting area on the surface of the mounting plate 31; the first fixed protrusion 34, the second fixed protrusion 35, the first clamp 32 and the second clamp 33 cooperate with each other to limit the detection head 4, ensuring that the detection head 4 will not become loose during the movement, resulting in a large error in the measurement accuracy.

[0029] A better solution is that a clamping plate 36 is further provided on the side facing each other of the first fixing protrusion 34 and the second fixing protrusion 35. The first fixing protrusion 34 and the second fixing protrusion 35 are connected to the clamping plate 36 on the same side through an adjusting screw 37. When in use, the technician can rotate the adjusting screw 37 to move the clamping plates 36 toward each other, thereby clamping and fixing the detection head 4, thereby further ensuring the assembly stability of the detection head 4.

[0030] The advantages of the present invention are: 1. Through the cooperation of the mobile device and the support arm, the detection head can be moved to any position in the detection space and remain stationary, without the need for manual measurement. The position accuracy obtained is better and the data is more accurate; 2. The first clamp and the second clamp are used to quickly remove and support the mounting plate, and the avoidance gap formed between the first clamp and the second clamp can support a variety of detection heads of different specifications.

[0031] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
