Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1-3 As shown, the embodiment of the utility model includes:

[0018] A wireless charger testing device comprises a cabinet 1, a main bracket 2, a y-axis servo linear module 3, a product tooling 4, a z-axis servo linear module 5, a lifting platform 6, a fine-tuning support 7, and a wireless charging module 8. The cabinet 1 is provided with a y-axis servo linear module 3 guiding the main bracket 2, the y-axis servo linear module 3 is provided with the product tooling 4, the main bracket 2 is suspended with a z-axis servo linear module 5, the z-axis servo linear module 5 is mounted with a lifting platform 6, the edge of the lifting platform 6 is provided with a fine-tuning support 7, the fine-tuning support 7 is provided with an x-axis guide rod 9 and an x-axis line rail 10, the x-axis guide rod 9 is connected to a back plate 12 on the x-axis line rail 10 through an optical axis fixing clamp 11, and the back plate 12 is suspended with a wireless charging module 8 facing the product tooling 4.

[0019] Wherein, a hand screw 13 is provided on the optical axis fixing clamp 11 , and the hand screw 13 is crimped and connected to the x-axis guide rod 9 .

[0020] Furthermore, a FOD bracket 14 is provided directly below the wireless charging module 8 , a foreign body sample 15 is placed on the FOD bracket 14 , an x-axis telescopic cylinder 16 is provided on the back plate 12 , and the x-axis telescopic cylinder 16 is connected to the horizontally arranged FOD bracket 14 through a transfer arm 17 .

[0021] Furthermore, the wireless charging module 8 is composed of a base 18, a charging coil, and a control circuit board 19. A coil mold 20 with a downward opening is provided on the base 18, and a charging coil is embedded in the coil mold 20. A control circuit board 19 electrically connected to the charging coil is mounted next to the base 18.

[0022] Furthermore, the foreign object sample 15 is placed directly below the charging coil.

[0023] Furthermore, the lifting platform 6 is hoisted with a z-axis slide cylinder 21, and the z-axis slide cylinder 21 is connected to a horizontal cantilever 22 below. A card holder 23 is provided on the bottom surface of the horizontal cantilever 22, and an NFC sample card 24 matching the wireless charging module 8 is inserted into the card holder 23.

[0024] Furthermore, there are two wireless charging modules 8 symmetrically arranged on the left and right sides of the lifting platform 6, and the x-axis telescopic cylinders 16 on each side face back to back.

[0025] The Y-axis servo linear module 3 is used to carry the product tooling 4 and guide it to the main bracket 2, on which the product tooling 4 loaded with the vehicle-mounted wireless charger is placed. This equipment is used to implement EOLT terminal testing of different models of vehicle-mounted wireless chargers.

[0026] The product is manually placed from the door of the cabinet 1, and is sent to the designated position directly below the wireless charging module 8 by the y-axis servo linear module 3. After the tooling is in place, the z-axis servo linear module 5 drives the lifting platform 6 downward, so that the wireless charging module 8 enters the charging range of the vehicle-mounted wireless charger. The vehicle-mounted wireless charger shown in this embodiment has three charging coils in different positions. The y-axis servo linear module 3 will switch to different positions, and the same wireless charging module 8 is used to perform three test items on the charging coils in three different positions. According to the size changes that occur after the tooling 4 of different products is changed, this device is equipped with a fine-tuning support 7 for each wireless charging module 8, that is, the position of the back plate 12 on the x-axis guide rod 9 is adjusted by hand-tightening the screw 13, thereby controlling the reference position of the wireless charging module 8 on the x-axis, and adjusting it once after each change of type to adapt to the tested products of different specifications. The test items include a FOD foreign body detection, which needs to be assisted by the foreign body sample 15. Therefore, the x-axis telescopic cylinder 16 is designed to load the FOD bracket 14, so that the foreign body sample 15 can be blocked on the charging coil of the vehicle-mounted wireless charger as needed, simulating the foreign body blocking process. The test items include an NFC identification detection, which needs to be assisted by the NFC sample card 24. Therefore, the z-axis slide cylinder 21 is designed to load the NFC sample card 24, so that the NFC sample card 24 can be detected and identified by the NFC module in the vehicle-mounted wireless charger as needed, thereby realizing the corresponding test process. Here, the card holder 23 is used to facilitate the change of type and improve the overall compatibility. In addition, the whole machine is equipped with two y-axis servo linear modules 3 to form two test stations, each of which is equipped with two wireless charging modules 8, so that the synchronous test of four vehicle-mounted wireless charging modules 8 can be realized at the same time. In order to avoid the problem of mutual interference of the FOD brackets 14, the adjacent x-axis telescopic cylinders 16 are arranged back to back to improve the safety during the synchronous operation.

[0027] In summary, the utility model provides a wireless charger testing device, which adopts multiple linear modules and cylinders to achieve rapid switching and precise docking of test items, and realizes rapid changeover for the EOLT process through components such as the FOD bracket 14, the card tray 23, and the fine-tuning support 7. The whole machine has the characteristics of compact structure, simple operation, and easy management.
