[0034] like Figures 1 to 5 As shown, the testing equipment includes a base 10, a shielding cover 20, a fan assembly 30, and a switch assembly 40. The base 10 has a placement area 11 for placing the test object. The base 10 also includes a test fixture (not shown) and a test power supply 70. The test fixture is located in the placement area 11 and is used to place the test object. The test power supply 70 is electrically connected to the test object placed in the test fixture to supply power to the test object.

[0035] The shield 20 is movably connected to the base 10, and the shield 20 can move relative to the base 10 to a first position or a second position. The fan assembly 30 is disposed on the shield 20 and moves synchronously with the shield 20.

[0036] A switch assembly 40 is disposed between the base 10 and the shielding cover 20 and is electrically connected to the fan assembly 30. The switch assembly 40 is used to be electrically connected to a power supply device (not shown) and is used to switch the on / off state as the shielding cover 20 moves. The power supply device is used to supply power to the fan assembly 30 when the switch assembly 40 is on.

[0037] When the shielding cover 20 is in the first position, it covers the base 10 and blocks the placement area 11, and the switch assembly 40 is turned on to make the fan assembly 30 conductive with the power supply. When the shielding cover 20 is in the second position, it separates from the base 10 to expose the placement area 11, and the switch assembly 40 is turned off to de-energize the fan assembly 30 with the power supply.

[0038] Before testing, the shield 20 can be positioned in the second position to separate it from the base 10. In this position, the shield 20 opens, exposing the placement area 11 for the user to place the test object onto the test fixture. Simultaneously, the switch assembly 40 is disconnected, and the fan assembly 30 is de-energized from the power supply, temporarily preventing it from starting.

[0039] During formal testing, the shielding cover 20 can be positioned in the first position, covering the base 10. At this time, the shielding cover 20 is closed, blocking the placement area 11, and the test power supply 70 supplies power to the test object. The shielding cover 20 then covers the test object, establishing an electromagnetic shielding space between the shielding cover 20 and the base 10. Simultaneously, the switching assembly 40 is turned on, and the power supply provides power to the fan assembly 30. The fan assembly 30 automatically starts operating, accelerating the gas exchange between the inside and outside of the shielding cover 20 for better heat dissipation.

[0040] In this way, the testing equipment can provide electromagnetic shielding space using the shielding cover 20 to ensure test accuracy and signal integrity during the test process. On the other hand, it can use the fan assembly 30 to dissipate heat from the test object to prevent the test object from overheating during long-term testing, thus keeping the temperature of the test environment within a certain range.

[0041] Furthermore, the opening and closing of the shielding cover 20 is linked to the conduction state switching of the switch assembly 40, and the fan assembly 30 can automatically start or stop working as the shielding cover 20 opens and closes, making operation simpler and more convenient and improving testing efficiency.

[0042] On the other hand, compared with the heat dissipation schemes that use air ducts and compressors in related technologies, this embodiment directly uses the fan 31 to dissipate heat inside the shield 20, which has a better heat dissipation effect and does not require additional compressors, making the design simpler and reducing hardware costs.

[0043] In this embodiment, the testing equipment further includes a drive component 50, which is connected to the shielding cover 20. The drive component 50 is used to drive the shielding cover 20 to move relative to the base 10 to a first position or a second position. In this way, the drive component 50 can drive the shielding cover 20 to move to the first position or the second position, while simultaneously switching the conduction state of the switch component 40.

[0044] In this embodiment, the shielding cover 20 and the base 10 are slidably engaged along a first direction, and the shielding cover 20 moves to a first position or a second position by sliding along the first direction. For example, the first direction is the vertical direction, and the X direction shown in the figure is used as an example of the first direction.

[0045] Thus, the shielding cover 20 moves to the first position or the second position by lifting. When the shielding cover 20 rises from the first position to the second position, it is suspended above the base 10, allowing it to open. When the shielding cover 20 descends from the second position to the first position, it covers the top of the base 10, closing it.

[0046] Figure 6A schematic diagram of the shielding cover provided in the first embodiment of this application.

[0047] Please refer to the following: Figure 6 In this embodiment, the shielding cover 20 is generally rectangular, hollow inside, and has an opening at the bottom. The shielding cover 20 has ventilation openings 21 corresponding to the fan assembly 30, extending through both the inner and outer sides of the shielding cover 20. The number and position of the ventilation openings 21 correspond to the number and position of the fan assembly 30.

[0048] Figure 7 A schematic diagram of the airflow of the fan assembly according to the first embodiment provided in this application.

[0049] Please refer to the following: Figure 7 In this embodiment, the fan assembly 30 includes a plurality of fans 31, all of which are disposed on the shielding cover 20 and are electrically connected to the switch assembly 40. The fans 31 are spaced apart on the shielding cover 20, which has a plurality of corresponding ventilation openings 21, with each fan 31 disposed in a corresponding ventilation opening 21. For example, the fans 31 have spacing in both the horizontal and vertical directions.

[0050] In this embodiment, the multiple fans 31 are respectively an intake fan 311 and an exhaust fan 312. Both the intake fan 311 and the exhaust fan 312 are disposed on the shielding cover 20. The intake fan 311 is used to blow air from the outside of the shielding cover 20 to the inside of the shielding cover 20, and the exhaust fan 312 is used to blow air from the inside of the shielding cover 20 to the outside of the shielding cover 20.

[0051] The intake fan 311 and the exhaust fan 312 work together to form a circulation through directional airflow. The intake fan 311 introduces external cold air, and the exhaust fan 312 discharges the hot air inside the shield 20, accelerating air circulation and preventing heat from accumulating inside the shield 20.

[0052] For example, the intake fan 311 and the exhaust fan 312 are both fans of the same size (e.g., 6cm × 6cm). The fan 31 with blades rotating clockwise serves as the intake fan 311, and the fan 31 with blades rotating counterclockwise serves as the exhaust fan 312. By utilizing the counter-rotation between the intake fan 311 and the exhaust fan 312, airflow collisions caused by rotating in the same direction can be avoided, reducing airflow conflict and dead zones, and forming a directional airflow circulation.

[0053] In this embodiment, the intake fan 311 and the exhaust fan 312 are located on different surfaces of the shielding cover 20. For example, the intake fan 311 is disposed on the side of the shielding cover 20, and the exhaust fan 312 is disposed on the top of the shielding cover 20. The side of the shielding cover 20 has a ventilation opening 21 corresponding to the intake fan 311, and the top of the shielding cover 20 has a ventilation opening 21 corresponding to the exhaust fan 312.

[0054] Thus, the shield 20 achieves top airflow through the exhaust fan 312, which conforms to the physical property of hot air rising and can more efficiently exhaust the internal high-temperature airflow. At the same time, the shield 20 achieves side airflow through the intake fan 311, which utilizes the natural flow of ambient cold air to form a stable thermal pressure difference to drive airflow circulation, thereby optimizing airflow circulation, improving heat dissipation efficiency, reducing the risk of local overheating, and improving heat dissipation uniformity.

[0055] In this embodiment, the voltage of the fan assembly 30 is the same as the voltage of the test power supply 70, wherein the voltage of the test power supply 70 can be configured according to the test voltage required by the test object. The selection of the fan assembly 30 can be configured according to the test voltage required by the test object to ensure that the voltage of the fan assembly 30 is consistent with the voltage of the test power supply 70. For example, if the test power supply 70 uses a 7V / 9A power supply module, the voltage of the fan assembly 30 can be configured to 7V.

[0056] In this way, the test power supply 70 is used as a power supply device for the fan assembly 30. That is, the switch assembly 40 is electrically connected to the test power supply 70, and the test power supply 70 supplies power to the fan assembly 30. The test equipment does not need to configure an additional power supply for the fan assembly 30 or introduce an additional power adapter, thereby saving costs.

[0057] Figure 8 A schematic diagram of the shielding mesh and fan provided in the first embodiment of this application.

[0058] Please refer to the following: Figure 8 In this embodiment, the shielding cover 20 is provided with a shielding mesh 60, which is located at the ventilation opening 21 and has multiple mesh openings. For example, the shielding mesh 60 can be a copper mesh, and it wraps around and covers the fan 31. The shielding mesh 60 ensures ventilation at the ventilation opening 21, guaranteeing heat dissipation, and also provides electrical signal shielding at the ventilation opening 21, ensuring the shielding performance of the shielding cover 20.

[0059] In this embodiment, the drive assembly 50 can be a cylinder mechanism, which has a cylinder seat 51 and a piston rod 52. The cylinder seat 51 is fixed to the base 10, and the piston rod 52 is parallel to the first direction. The piston rod 52 is provided with a drive block 53, which is fixedly connected to the top of the shield 20. The working principle of the cylinder mechanism is as follows: by driving the piston cylinder to reciprocate relative to the cylinder seat 51 along the first direction, the piston rod 52 moves synchronously with the shield 20 through the drive block 53, so that the shield 20 moves to the first position or the second position. In other embodiments, the drive assembly 50 can also be a gear and rack mechanism, a lead screw mechanism, etc., as long as it can realize the movement of the shield 20. This application does not impose any restrictions on this.

[0060] Please see Figure 1 In this embodiment, the shielding cover 20 is provided with a mounting block 22, which is located on the top of the shielding cover 20. One end of the mounting block 22 is fixedly connected to the shielding cover 20, and the other end of the mounting block 22 extends out of the shielding cover 20 and is provided with a guide post 23. The guide post 23 extends along a first direction.

[0061] The base 10 is provided with a fixed cylinder 12, and a guide post 23 is inserted into the interior of the fixed cylinder 12 and slides in cooperation with the fixed cylinder 12 along a first direction. For example, the fixed cylinder 12 is fixedly connected to one side of the base 10. The upper end of the guide post 23 is fixedly connected to the mounting block 22, and the lower end of the guide post 23 is inserted into the interior of the fixed cylinder 12. A sliding bearing forms a sliding fit between the guide post 23 and the fixed cylinder 12. When the shielding cover 20 moves along the first direction, both the mounting block 22 and the guide post 23 move synchronously with the shielding cover 20, and the guide post 23 slides relative to the fixed cylinder 12 to guide and limit the movement of the shielding cover 20.

[0062] In this embodiment, the mounting block 22, guide post 23 and fixing cylinder 12 are arranged in pairs and distributed on opposite sides of the shielding cover 20. In this way, both sides of the shielding cover 20 can be moved and guided at the same time, improving the stability and smoothness of the overall movement of the shielding cover 20.

[0063] In this embodiment, the switch assembly 40 includes a power supply conductive element 41 and a switch conductive element 42, which are disposed opposite to each other in a first direction. The power supply conductive element 41 is fixed to the base 10 and is electrically connected to the power supply device. The switch conductive element 42 is fixed to the shielding cover 20 and is electrically connected to the fan assembly 30. When the shielding cover 20 is in the first position, the power supply conductive element 41 is in contact with the switch conductive element 42, and the switch assembly 40 is turned on. When the shielding cover 20 is in the second position, the power supply conductive element 41 is separated from the switch conductive element 42, and the switch assembly 40 is turned off.

[0064] For example, the power supply conductive element 41 is fixedly connected to the upper end of the fixed cylinder 12, and the switch conductive element 42 is fixedly connected to the mounting block 22. When the shielding cover 20 moves from the first position to the second position, the mounting block 22 moves away from the fixed cylinder 12 to separate the power supply conductive element 41 from the switch conductive element 42. When the shielding cover 20 moves from the second position to the first position, the mounting block 22 moves toward the fixed cylinder 12 to bring the power supply conductive element 41 into contact with the switch conductive element 42. By respectively setting the switch conductive element 42 and the power supply conductive element 41 on the mounting block 22 and the fixed cylinder 12, it is possible to ensure that the switch conductive element 42 and the power supply conductive element 41 can be aligned in the first direction, avoiding poor contact caused by positional deviation between the switch conductive element 42 and the power supply conductive element 41.

[0065] Specifically, the side of the switch conductive element 42 facing the power supply conductive element 41 is provided with positive and negative probes. The positive and negative probes can be elastic probes, and the positive and negative probes are respectively electrically connected to the air intake fan 311 and the air exhaust fan 312 through lead wires.

[0066] Specifically, the side of the power supply conductive component 41 facing the switch conductive component 42 is provided with positive and negative conductive blocks. These positive and negative conductive blocks are respectively positioned opposite to their corresponding positive and negative probes in a first direction. Both positive and negative conductive blocks are electrically connected to the power supply device via leads. When the shielding cover 20 is in the first position, the positive and negative probes are in contact with their corresponding positive and negative conductive blocks. When the shielding cover 20 is in the second position, the positive and negative probes are separated from their corresponding positive and negative conductive blocks.

[0067] Figure 9 This is a front structural diagram of the test device provided in the second embodiment of this application. Figure 10 This is a schematic diagram of the back of the test device provided in the second embodiment of this application.

[0068] like Figure 9 and Figure 10 As shown, the second embodiment differs from the first embodiment in that: the shielding cover 20 is entirely covered by the base 10, and the shielding cover 20 has a front 24, a back 25, and two side 26 formed around its periphery, wherein the front 24 and the back 25 are arranged opposite to each other, and the two side 26 are arranged opposite to each other. The front 24 of the shielding cover 20 has a switch opening 28, and a blocking door 27 is provided on the front 24. The blocking door 27 is rotatably connected to the shielding cover 20. By rotating the blocking door 27, the switch opening 28 can be opened or closed, so that the base 10 is exposed or hidden within the shielding cover 20.

[0069] The shielding cover 20 has multiple ventilation openings 21, which are distributed on different surfaces of the shielding cover 20 and have different heights. For example, the multiple ventilation openings 21 are located on the back 25 and the side 26 of the shielding cover 20, and the ventilation openings 21 located on the side 26 of the shielding cover 20 are higher than the ventilation openings 21 located on the back 25 of the shielding cover 20.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
