Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing fixture for wireless chargers. Background Technology

[0002] Currently, wireless chargers on the market typically have three coils. However, current testing fixtures usually test all three coils simultaneously. This testing method can only determine whether the wireless charger can charge normally, but it cannot guarantee that each coil is in a normal working state. Furthermore, even if a problem is detected, such as reduced charging efficiency, it is impossible to directly determine which coil is faulty. Summary of the Invention

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-2 The wireless charger testing fixture shown includes a left coil testing piece 1, a middle coil testing piece 2, and a right coil testing piece 3 arranged from top to bottom. Specifically, the left coil testing piece 1, the middle coil testing piece 2, and the right coil testing piece 3 are connected by a hinge shaft 41 near one side. A base 4 is fixed to the bottom of the hinge shaft 41, and the base 4 is used to place the wireless charger to be tested.

[0026] like Figure 2-3 As shown, the left coil detection piece 1, the middle coil detection piece 2, and the right coil detection piece 3 are all provided with a groove 11 in the middle. An electromagnetic shielding layer 21 is provided at the bottom of the groove 11. The groove 11 of the left coil detection piece 1, the middle coil detection piece 2, and the right coil detection piece 3 are all provided with a detection port 31. The detection port 31 of the middle coil detection piece 2 is located in the middle. The detection ports 31 of the left coil detection piece 1 and the right coil detection piece 3 are offset to both sides relative to the detection port 31 of the middle coil detection piece 2, so as to correspond to the positions of the three coils of the wireless charger.

[0027] like Figure 1-2 As shown, the hinge shaft 41 is provided with two positioning nuts 411. The left coil detection piece 1, the middle coil detection piece 2 and the right coil detection piece 3 are all provided with hinge holes 12 on one side. All hinge holes 12 are located between the two positioning nuts 411. Specifically, the left coil detection piece 1, the middle coil detection piece 2 and the right coil detection piece 3 are all rectangular structures, and the hinge holes 12 are located at one corner.

[0028] like Figure 4As shown, the hinge shaft 41 is a telescopic rod structure, such as the umbrella handle structure or fishing rod structure. The base 4 is provided with a round hole 42, and the hinge shaft 41 is installed in the round hole 42. The hinge shaft 41 can be retracted into the round hole 42. Specifically, the base 4 is provided with a detection piece fixing recess 43, which is used to fix the left coil detection piece 1, the middle coil detection piece 2 and the right coil detection piece 3.

[0029] like Figure 4 As shown, the base 4 has a wireless charger fixing recess 44 in the middle for fixing the wireless charger.

[0030] Example 2

[0031] like Figure 5-6 As shown, the difference between this embodiment and embodiment 1 is that: the bottom of the hinge hole 12 of the left coil detection piece 1 is provided with a deep recess 32, the top of the hinge hole 12 of the right coil detection piece 3 is provided with a deep recess 32, and the two sides of the hinge hole 12 of the middle coil detection piece 2 are provided with shallow recesses 22. The sum of the depths of the two shallow recesses 22 is equal to the depth of the deep recess 32, which is equal to 2 / 3 of the thickness of the left coil detection piece 1, the middle coil detection piece 2, or the right coil detection piece 3, so that the left coil detection piece 1, the middle coil detection piece 2, and the right coil detection piece 3 can form a whole plane after being unfolded.

[0032] like Figure 7 As shown, the top of the right coil detection piece 3 is provided with an upward inclined surface 33 on one side of the hinge hole 12, and the bottom of the left coil detection piece 1 and the middle coil detection piece 2 are provided with downward inclined surfaces 23 on the other side of the hinge hole 12. When the left coil detection piece 1, the middle coil detection piece 2 and the right coil detection piece 3 are unfolded into a plane, the downward inclined surface 23 of the left coil detection piece 1 contacts the upward inclined surface 33, and continues to rotate so that the left coil detection piece 1 rises to the top of the right coil detection piece 3; then the downward inclined surface 23 of the middle coil detection piece 2 contacts the upward inclined surface 33, and also continues to rotate so that the middle coil detection piece 2 enters between the right coil detection piece 3 and the left coil detection piece 1.

[0033] Specifically, the bottom of the left coil detection piece 1 is provided with a rounded chamfer 13 on one side of the hinge hole 12, which facilitates the middle coil detection piece 2 to enter between the right coil detection piece 3 and the left coil detection piece 1.
