Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging, and particularly to a test device for a wireless charging power supply of an electric vehicle. Background Art

[0002] Wireless charging is a technology that uses electromagnetic induction, magnetic resonance, radio wave transmission and other technologies to charge electronic devices without using traditional charging cables. This is the most common wireless charging principle at present. When an alternating current passes through the transmitting coil, an alternating magnetic field will be generated. When the receiving coil is close to the transmitting coil, according to the principle of electromagnetic induction, an induced electromotive force will be generated in the receiving coil, thereby generating an induced current. After this current is rectified, regulated, etc., it can charge the electronic device. This charging method has a relatively high charging efficiency, but the charging distance is relatively short, generally between a few millimeters and dozens of millimeters.

[0003] A Chinese invention patent with the publication number CN108692756B discloses a test bracket for a wireless charging device, which includes a vertical movement mechanism for installing a receiving coil and driving its vertical movement, a horizontal movement mechanism for installing a transmitting coil and driving its horizontal movement, and a support mechanism for installing the vertical movement mechanism and the horizontal movement mechanism. During the test, the distance between the receiving coil and the transmitting coil can be changed by operating the vertical movement mechanism, and the relative offset between the receiving coil and the transmitting coil can also be changed by operating the horizontal movement mechanism. At the same time, through the combined action of the two, the charging coil test of the wireless charging pile device can be successfully completed. And because the manual movement operation of the receiving coil and the transmitting coil is abandoned and replaced by the mechanical movement of the vertical movement mechanism and the horizontal movement mechanism, the movement adjustment of the receiving coil and the transmitting coil has high precision and accuracy, and at the same time, the test precision and the reliability of the test results are improved.

[0004] In addition, due to the wide range of power requirements of electric vehicles, from low-power small scooters to high-power electric motorcycles and electric vehicles, the output power of wireless charging power supplies varies significantly. When charging at low power, a small number of turns and a thin wire diameter of the transmitting coil can meet the requirements; for high-power charging, a coil with more turns and a thicker wire diameter is required to withstand large currents, reduce heat generation and energy loss. Therefore, during the testing process of this device, it is impossible to quickly replace the transmitting coil of the corresponding specification according to the power level of the wireless charging power supply, nor can it accurately simulate the power scenario during its actual operation, so as to accurately evaluate the performance of the power supply at different powers. Since wireless charging relies on magnetic field coupling between the transmitting coil and the receiving coil to transfer energy, the relative position and distance will affect the magnetic field coupling efficiency, which will not only affect the detection accuracy of the wireless charging power supply, but also affect the energy transfer efficiency. Therefore, a test bracket for a wireless charging device disclosed in Chinese invention patent CN108692756B cannot adapt to the detection of diverse wireless charging power supplies, nor can it optimize the magnetic field coupling effect.

The spherical rod 3036 is clamped inside the spherical clamping groove block 4038. The spherical clamping groove block 4038 slides inside the chute three 3035.

[0049] It should be noted that: Both ends of the receiving coil are clamped between the two conductive blocks 4036, and the current is transmitted to the inside of the conductive groove plate 4037 through the conductive blocks 4036.

[0050] The working process and principle of the above embodiment are as follows:

[0051] The initial state is as follows: The first abutting block 2045 is at the outer end of the arc-shaped sliding groove 2047, the torsion spring 4033 is in a relaxed state, the spring 3037 is in an uncompressed state, and the telescopic sliding plate 301 is in an unextended state.

[0052] The working steps are as follows:

[0053] The operator rotates the rotating plate 2046 in the forward direction, causing the rotating plate 2046 to rotate at the top of the first mounting plate 2042, causing the rotating plate 2046 to drive the arc-shaped sliding groove 2047 to rotate synchronously, causing the arc-shaped sliding groove 2047 to abut against the first abutting block 2045 and rotate synchronously, causing the first abutting block 2045 to drive the baffle plate 2044 to slide inwardly of the rotating plate 2046 between the two limiting plates 2043. Subsequently, the transmitting coil is sleeved on the outer wall of the first mounting plate 2042. Subsequently, both ends of the transmitting coil are connected to the conducting head 202 through the mounting groove 2041. Subsequently, the operator rotates the rotating plate 2046 in the reverse direction, causing the rotating plate 2046 to drive the baffle plate 2044 to move outwardly of the rotating plate 2046, causing the baffle plate 2044 to clamp and fix the transmitting coil. Subsequently, the operator controls the power transmitter 201 to start working through an external control device, causing the power transmitter 201 to supply current to the transmitting coil through the conducting head 202.

[0054] After the transmitting coil is installed, the operator pulls the rotating rod 4032 outward to move it relative to the mounting bracket 3038. As a result, the rotating rod 4032 drives the first fixing block 4031 outward relative to the mounting bracket 3038 through the torsion spring 4033. The rotating rod 4032 and the first fixing block 4031 then drive the first clamping groove plate 401 and the second clamping groove plate 4034 outward relative to the mounting bracket 3038. The spherical groove blocks 4038 connected to the outer walls of the first clamping groove plate 401 and the second clamping groove plate 4034 move synchronously. The spherical groove blocks 4038 abut against the spherical rods 3036, causing the spherical rods 3036 to move into the inner part of the second chute 3034. Consequently, the spherical rods 3036 compress the springs 3037 until the spherical rods 3036 move outside the spherical groove blocks 4038. At this point, the operator continues to pull the rotating rod 4032 and the first fixing block 4031 outward relative to the mounting bracket 3038, and then removes the first clamping groove plate 401 and the second clamping groove plate 4034. The first clamping groove plate 401 is driven by the second fixing block 4035 to rotate upward around the rotating rod 4032 as the axis, causing the first fixing block 4031 to drive the torsion spring 4033 to start twisting. As a result, the first clamping groove plate 401 separates from the second clamping groove plate 4034. Subsequently, the operator places the receiving coil inside the first clamping groove plate 401 and the second clamping groove plate 4034. The first clamping groove plate 401 and the second clamping groove plate 4034 close under the elastic action of the torsion spring 4033. The first clamping groove plate 401 and the second clamping groove plate 4034 then drive the conductive blocks 4036 to close, and the conductive blocks 4036 clamp and fix both ends of the receiving coil. Subsequently, the operator aligns the second fixing block 4035 with the chute plate 3039 and pushes the first fixing block 4031 and the rotating rod 4032 inward relative to the mounting bracket 3038. The first fixing block 4031 and the rotating rod 4032 drive the first clamping groove plate 401 and the second clamping groove plate 4034 to move inward relative to the mounting bracket 3038, and the conductive blocks 4036 enter the inner part of the conductive chute plate 4037. At the same time, the spherical rods 3036 are engaged with the spherical groove blocks 4038 again under the action of the spherical groove blocks 4038 and the springs 3037. This enables the rapid replacement of receiving coils with different numbers of turns. By means of the adjusting assembly 402 and the mounting assembly 203, receiving coils and transmitting coils with various numbers of turns and diameters can be replaced. This allows the device to quickly replace the corresponding specification coils according to the power levels of different wireless charging power supplies, thereby accurately evaluating the performance of the power supply at different powers and improving the test efficiency of the power supply.

[0055] Subsequently, the display 3032 controls the telescopic slide plate 301 to slide inside the first chute 102 towards the side close to the transmitting coil, so that the transmitting coil and the receiving coil are on the same vertical plane. Thus, the magnetic field generated after the transmitting coil is powered on is transmitted to the inside of the receiving coil. The current generated after the receiving coil receives the magnetic field is transmitted to the inside of the conductive groove plate 4037 through the conductive block 4036, and then transmitted to the inside of the detector 3031 through the conductive groove plate 4037. Then, it is transmitted to the inside of the display 3032 through the detector 3031 and analyzed and recorded by the display 3032. Subsequently, the display 3032 controls the telescopic slide plate 301 to start extending, so that the telescopic slide plate 301 drives the receiving coil to move vertically upward through the second mounting plate 3033 and the mounting bracket 3038, enabling the display 3032 to record the current change during the movement of the receiving coil and analyze the optimal position. By the display 3032 timely recording the current values of the transmitting coil and the receiving coil, the energy values of magnetic field coupling transmission of various transmitting coils and receiving coils under different power supplies can be reflected. Thus, the optimal coil model can be equipped with different power supplies, thereby improving the charging efficiency of the electric vehicle.
