For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example, see Figures 1 to 6 , a detection device for a wireless charging module of an electric vehicle, comprising a test bench 1, on which two loading support plates 2 arranged opposite to each other are arranged, and the loading support plates 2 are connected to a rotating test plate 3 through a rotating switching component;

[0032] Furthermore, the rotation switching component includes an assembly port opened in the loading support disk 2, the rotating test disk 3 is located in the assembly port and is rotatably connected to the inner wall of the assembly port, a rotating motor 14 is arranged on the loading support disk 2, a rotating gear ring 15 is arranged at the bottom of the rotating test disk 3, the output end of the rotating motor 14 passes through the assembly port and is fixedly connected to a rotating gear 16 meshing with the rotating gear ring 15.

[0033] The rotating test disk 3 connected to the rotating gear ring 15 is rotated by the rotating motor 14 through the rotating gear 16. When the installation test mold 5 on the rotating test disk 3 needs to be changed, it can be achieved by rotating the rotating test disk 3, thereby meeting the effect of conducting multiple control test groups synchronously during the test.

[0034] A plurality of sliding combination openings 4 are provided on the rotating test disk 3, and the inner wall of the sliding combination opening 4 is connected to the installation test mold 5 through a sliding connection. Furthermore, the sliding connection includes a limiting sliding opening provided on the opposite side wall of the sliding combination opening 4, and the side wall of the installation test mold 5 is fixedly connected to a limiting side block 20 connected to the limiting sliding opening, and a matching opening 21 adapted to the sliding combination opening 4 is provided on the loading support disk 2.

[0035] The sliding connection piece can be used to achieve a sliding connection between the installation test mold 5 and the sliding combination opening 4, so that the wireless charging module on the installation test mold 5 can be moved outward, thereby increasing the distance between multiple wireless charging modules being tested, thereby exploring whether there is interference between adjacent wireless charging modules and the relationship between the charging distance and charging interference of adjacent wireless charging modules in the test.

[0036] A joint control drive component for controlling the movement of the installation test mold 5 is arranged in the rotating test disk 3, and the joint control drive component includes a joint control cavity opened in the rotating test disk 3, and a joint control motor 22 is arranged in the rotating test disk 3. A fine-tuning vertical lead screw 23 is fixedly connected to the output end of the joint control motor 22, and an adjustment disk 24 is threadedly connected to the outer wall of the fine-tuning vertical lead screw 23. The adjustment disk 24 is connected to the installation test mold 5 through a joint control adjustment rod 25.

[0037] By setting up a joint control drive component, multiple installation test molds 5 can be moved outward synchronously. The fine-tuning vertical screw 23 driven by the joint control motor 22 can accurately control the moving distance of each installation test mold 5, making it convenient to adjust the distance data.

[0038] A rectangular through-hole 26 communicating with the joint control cavity is provided at the bottom of the sliding combination port 4. One end of the joint control adjusting rod 25 is rotatably connected to the adjusting disk 24 via a rotating shaft, and the other end extends upward through the rectangular through-hole 26 and is connected to the installation test mold 5 via a U-shaped rotating member 27.

A telescopic gas rod 8 is arranged in the telescopic mounting opening 7. The output end of the telescopic gas rod 8 is connected to the loading support plate 2 located at the bottom. The telescopic gas cylinder 8 can control the height of the loading support plate 2 located below to change, so as to realize the change of the distance between the electric vehicle wireless charging module in the test mold 5 installed on the loading support plate 2 and the upper power supply wireless charging module 17.

[0040] A power wireless charging module 17 is arranged in the installation test mold 5 located at the top, and a test placement opening 18 is opened in the installation test mold 5 located at the bottom. A temperature detection component 19 is arranged on the inner wall of the test placement opening 18. The setting of the temperature detection component 19 can detect the temperature of the electric vehicle wireless charging module in the test placement opening 18 at all times. When the electric vehicle wireless charging module is tested, the electric vehicle wireless charging module can be installed therein through the test placement opening 18 for a control test.

[0041] The electric vehicle wireless charging module is placed in the test placement port 18 and is externally connected to a test battery. The performance of the electric vehicle wireless charging module is determined by the change in the battery input power.

[0042] The side wall of the support frame 6 is connected to a shielding cover 9 through a support rod. The setting of the shielding cover 9 can block the magnetic field interference between the electric vehicle wireless charging modules moved to the outside, so as to meet the test under the premise of avoiding mutual interference. A plurality of expansion openings 10 are opened on the shielding cover 9, and a plurality of test isolation plates 11 that can be detachably installed by inserting mounting parts are provided on the shielding cover 9;

[0043] Furthermore, the plug-in mounting part includes a combination plug 28 arranged on the shielding cover 9, and a combination socket compatible with the combination plug 28 is opened on the test isolation plate 11. There are multiple test isolation plates 11, and the materials of each test isolation plate 11 are different according to the test requirements. The test isolation plates 11 made of different materials have different effects on wireless charging in the magnetic field. The selection of the shell of the electric vehicle wireless charging module can be achieved by changing different materials, and the material with the least impact should be selected as much as possible.

[0045] The electromagnetic generator 12 changes the size of the magnetic field by passing an electric current, and the electromagnetic radiation tester 13 changes the upper and lower heights by controlling the electric telescopic rod, thereby meeting the adjustment needs during the test and realizing the test of electromagnetic radiation at different heights and distances. The electromagnetic generator 12 and the electromagnetic radiation tester 13 are existing technologies and will not be described in detail here.

[0046] The detection results generated in the present invention are all determined by the power charged by the wireless charging module at the same time;

[0047] When testing the wireless charging module of an electric vehicle, the present invention places the wireless charging module of the electric vehicle in the test placement port 18 in the installation test mold 5 located below. During the test, the power supply wireless charging module 17 is turned on, and the installation test mold 5 where the wireless charging module of the electric vehicle and the power supply wireless charging module 17 are installed can be controlled to change positions respectively through the internally arranged joint control motor 22, thereby changing the corresponding areas of the wireless charging module of the electric vehicle and the power supply wireless charging module 17, so as to explore the influence of different corresponding areas on the wireless charging efficiency.

[0048] In the test project, the height of the electric vehicle wireless charging module in the test placement port 18 in the installation test mold 5 below is changed by controlling the telescopic gas rod, thereby changing the distance between the electric vehicle wireless charging module and the power supply wireless charging module 17, so as to explore the influence of different distances on the charging efficiency;

[0049] During the test, multiple test control groups can be controlled to perform synchronous tests, and during the test, the distances between the multiple control groups can be gradually changed (the joint control motor 22 can be used to shrink or expand to control the distances), so as to test the interference factors between the wireless charging modules during charging;

[0050] During the test, the electromagnetic generator 12 can be turned on and the size of the magnetic force can be controlled to interfere with the magnetic field between the wireless charging module of the electric vehicle and the wireless charging module 17 of the power supply, thereby exploring the efficiency and reliability of charging when the magnetic field is disturbed.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
