[0026] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in an embodiment of the present utility model, for the mini anechoic chamber 100 for anti-radiation interference testing, the mini anechoic chamber includes a first mounting plate 110, a connection structure 120, and a second mounting plate 130 that are sequentially connected, and the first mounting plate 110, the connection structure 120, and the second mounting plate 130 jointly enclose a sealed test space;
[0029] On one side of the first mounting plate 110 close to the connection structure 120, a wireless network transmitter 111 and an interference signal transmitter 112 are provided; the wireless network transmitter 111 is used to provide communication signals for electronic products, and the interference signal transmitter 112 is used to emit radiation signals to simulate external interference signals;
[0030] The second mounting plate 130 is provided with a rotating assembly 140 and a suspension member 150 for mounting the electronic product to be tested, and the rotating assembly 140 penetrates the second mounting plate 130; the suspension member 150 is connected to one side of the rotating assembly 140 close to the connection structure 120 and can change its position in the test space as the rotating assembly 140 rotates; the suspension member 150 is used to mount the electronic product.
[0031] It can be understood that the technical solution of the present utility model forms a closed test space by arranging a first mounting plate 110, a connection structure 120 and a second mounting plate 130, and the first mounting plate 110, the connection structure 120 and the second mounting plate 130 jointly enclose the closed test space; the anti-radiation interference test of the electronic product is carried out in the test space, and by only installing a wireless network transmitter 111 and an interference signal transmitter 112 in the test space, the occupation of the test site is reduced. Further, due to the narrow test space, in order to ensure the reliability of the test results, a rotating assembly 140 and a suspension member 150 for installing the electronic product to be tested are also provided. Specifically, the rotating assembly 140 penetrates through the second mounting plate 130; the suspension member 150 is connected to one side of the rotating assembly 140 close to the connection structure 120 and can change its position in the test space with the rotation of the rotating assembly 140, changing the different spatial positions of the electronic product, and improving the reliability of the test results.
[0032] It should be noted that the test space is a space capable of shielding external signals. In order to ensure that the electronic product can perform normal communication tests in the internal space, a wireless network transmitter 111 is provided in the internal space.
[0033] It should also be noted that the wireless network transmitter 111 and the interference signal transmitter 112 are only the transmitting devices of such signal amplifying or generating devices, and the wireless network transmitter 111 or the interference signal transmitter 112 may also be devices such as antennas or slot antennas.
[0034] Optionally, the interference signal generator may also be a device that emits electromagnetic wave interference signals or may also be a device that emits X-ray radiation signals.
[0035] Optionally, the rotating assembly 140 is a rotating cylinder.
[0036] Please refer to Figure 2 and Figure 3 , in a specific embodiment of the present utility model, the rotating assembly 140 includes an operation knob 141, a first tooth column 142, a second tooth column 143, a compression spring 144 and a limiting member 145;
[0037] The first tooth column 142 is fixed to one side of the second mounting plate 130 close to the connection structure 120; the second tooth column 143 meshes with the first tooth column 142, the operation knob 141 sequentially penetrates through the second mounting plate 130, the first tooth column 142, the second tooth column 143 and the compression spring 144, and the limiting member 145 is installed at one end of the operation knob 141 close to the compression spring 144; the compression spring 144 abuts against the limiting member 145 and the second tooth column 143 respectively; the second tooth column 143 and the operation knob 141 can rotate synchronously.
[0038] It can be understood that rotating the operation knob 141 can drive the second tooth column 143 to rotate, so that the second tooth column 143 rotates relative to the first tooth column 142. During the process of the second tooth column 143 rotating relative to the first tooth column 142, the second tooth column 143 moves away from the first tooth column 142, and the compression spring 144 is compressed, so that the compression spring 144 obtains the elastic potential energy of expansion. After the second tooth column 143 meshes with the first tooth column 142 again, the elastic potential energy obtained by the compression spring 144 is released, and the operation knob 141 stops rotating, so as to realize the relative fixation of the first tooth column 142 and the second tooth column 143.
[0039] Optionally, the cross-section of the through-hole for the operation knob 141 to penetrate through the second tooth column 143 is D-shaped, and the mating part of the operation knob 141 and the second tooth column 143 is also of D-shaped cross-section, so as to realize the synchronous rotation of the second tooth column 143 and the operation knob 141.
[0040] Optionally, the number of teeth of the first tooth column 142 or the second tooth column 143 is four or three or two.
[0041] Optionally, the first tooth column 142 and the second tooth column 143 can only rotate in one direction, and the other direction can realize the self-locking of the tooth column.
[0042] Optionally, the first tooth column 142 and the second mounting plate 130 are integrally formed.
[0043] Please continue to refer to Figure 3 , in a specific embodiment, the second tooth column 143 is further provided with a connecting rod 146, the connecting rod 146 is provided with a support member 147, and the support member 147 is used for connecting the suspension member 150.
[0044] It can be understood that the setting of the connecting rod 146 increases the spatial displacement of the electronic product. The support member 147 is used for hanging the suspension member 150, and the suspension member 150 can also change the spatial position of the electronic product by changing the connection position with the support member 147.
[0045] Specifically, as Figure 4 shown, the hanging member 150 includes a hanging rope 151 and a basket 152 connected to the hanging rope 151. The hanging rope 151 is connected to the support member 147, and the basket is used to place electronic products.
[0046] Please refer to Figure 1 and Figure 4 , in a preferred embodiment of the present application, the mini anechoic chamber 100 for anti-radiation interference testing further includes a test platform 160 and a guide rail 170; the guide rail 170 is fixed to the test platform 160 and is slidably engaged with the connection structure 120 and the second mounting plate 130 respectively.
[0047] It can be understood that the connection structure 120 can slide relative to the guide rail 170, which facilitates the maintenance of the first mounting plate 110; the second mounting plate 130 can slide relative to the guide rail 170, which facilitates the placement and removal of the electronic product to be tested.
[0048] Optionally, the test space further has a camera or a microphone. It can be understood that the camera or the microphone can be used to monitor the working state or response time of the electronic product.
[0049] As Figure 1 and Figure 4 shown, the mini anechoic chamber 100 for anti-radiation interference testing further includes a control device 180. The control device 180 is signal-connected to the first mounting plate 110 and is used to regulate the signal parameters of the wireless network transmitter 111 and the interference signal transmitter 112.
[0050] It can be understood that the control device 180 includes an analog signal generator for generating analog signals of different types and frequency bands.
[0051] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
