Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this invention is to provide a portable wireless charging tester for vehicles to solve the problems existing in the prior art. It is flexible in application, easy to operate, and can improve testing efficiency.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-5As shown, this utility model provides a portable wireless charging tester 100 for vehicles, including a wireless charging transmitting system 1, a support device 2, a first position adjustment component 3, a first driving device 4, a second position adjustment component 5, and a second driving device 6. Both the first position adjustment component 3 and the first driving device 4 are connected to the support device 2. The first position adjustment component 3 is connected to the first driving device 4, and the first driving device 4 can drive the first position adjustment component 3 to move along a first direction. The second position adjustment component 5 is connected to the first position adjustment component 3, and the second driving device 6 is connected to the support device 2. The second position adjustment component 5 is also connected to the second driving device 6, and the second driving device 6 can drive the second position adjustment component 5 to move along a second direction. The first and second directions are perpendicular to each other. The wireless charging transmitting system 1 can be connected to the second position adjustment component 5. The wireless charging transmitting system 1, the first position adjustment component 3, the first driving device 4, the second position adjustment component 5, and the second driving device 6 of this utility model are integrated on the support device 2, forming an independently usable wireless charging tester that is easy to carry. The first driving device 4 drives the first position adjustment component 3 to move along the first direction, and the second driving device 6 drives the second position adjustment component 5 to move along the second direction. This allows the relative position between the wireless charging transmitter system 1 and the vehicle receiver module to meet the needs of charging and testing. This design is flexible, easy to operate, and improves testing efficiency. It should be noted that the wireless charging transmitter system 1 is generally installed under the vehicle chassis during use, in which case both the first and second directions are horizontal.

[0029] In a preferred embodiment, the first adjusting assembly includes a first turbine, a first worm gear, and a first slider. A first driving device 4 is fixedly connected to the first turbine, the first turbine is connected to the first worm gear, the first worm gear is threadedly connected to the first slider, the first slider is slidably connected to a first slide rail 201 on the upper surface of the support device 2, and the first worm gear is rotatably connected to the support device 2. The first driving device 4 drives the first turbine to rotate around its own axis, and the first turbine drives the first worm gear to rotate around its axis, thereby causing the first slider to move linearly along the first worm gear.

[0030] In a preferred embodiment, the second adjustment assembly includes a second turbine, a second worm gear, and a second slider. A second drive device 6 is fixedly connected to the second turbine, the second turbine is connected to the second worm gear, the second worm gear is threadedly connected to the second slider, the second slider is slidably connected to a second slide rail 202 on the upper surface of the first slider, and the second worm gear is rotatably connected to the support device 2. The second slide rail 202 is perpendicular to the first slide rail 201. The second drive device 6 drives the second turbine to rotate around its own axis, which in turn drives the second worm gear to rotate around its axis, thereby causing the second slider to move linearly along the second worm gear.

[0031] This invention also includes an image acquisition device 7, which is fixedly connected to the support device 2. The image acquisition device 7 is used to acquire images of the vehicle-mounted receiving coil 801 of the vehicle-mounted receiving module 8. The image acquisition device 7 can be signal-connected to the display device 9. After the portable vehicle wireless charging tester 100 is placed near the vehicle-mounted receiving module 8, the image acquisition device 7 acquires images of the vehicle-mounted receiving coil 801, which are then displayed on the display device 9. The driver moves the vehicle based on the images to determine the relative position between the wireless charging transmitter system 1 and the vehicle-mounted receiving coil 801, so that the vehicle-mounted receiving coil 801 can be better positioned above the wireless charging transmitter system 1. The method of the driver moving the vehicle can be used in conjunction with the first position adjustment component 3 and the second position adjustment component 5 of the portable vehicle wireless charging tester 100. Moving the vehicle allows for the approximate positioning of the on-board receiving coil 801, while the first and second position adjustment components 3 and 5 enable precise positioning of the on-board receiving coil 801. This reduces the adjustment range of the first and second position adjustment components 3 and 5, facilitating miniaturization of the vehicle wireless charging tester. Furthermore, the first and second position adjustment components 3 and 5 can be adjusted during testing to change the relative position of the on-board receiving coil 801 and the wireless charging transmitter system 1, enabling testing under various operating conditions. After the position is adjusted to the desired test position, the on-board receiving coil 801 can receive the wireless energy from the wireless charging transmitter system 1 via electromagnetic induction and convert it into current for charging.

[0032] In a preferred embodiment, the image acquisition device 7 includes two cameras mounted diagonally on the support device 2. The display device 9 can be a display screen inside the vehicle or a display independent of the vehicle, such as a display of a portable device carried by the vehicle user.

[0033] This invention also includes a position control device, and the image acquisition device 7, the first driving device 4, and the second driving device 6 are all signal-connected to the position control device.

[0034] This invention also includes a height adjustment device 10, which is fixedly connected to the support device 2. The height adjustment device 10 can adjust the height of the support device 2. The height adjustment device 10 can adjust the vertical distance between the wireless charging transmitter system 1 and the vehicle-mounted receiver coil 801, adapting to vehicles with different chassis heights. It can connect with the vehicle-mounted receiver coil 801 on vehicles with different chassis heights for charging and testing, facilitating application.

[0035] This invention also includes a distance detection device, which is fixedly connected to the support device 2. Both the distance detection device and the height adjustment device 10 are signal-connected to the position control device. The distance detection device can detect the distance between the vehicle-mounted receiving coil 801 and the distance detection device. The distance between the distance detection device and the wireless charging transmitter 1 can be obtained based on their installation positions. Then, based on the distance between the vehicle-mounted receiving coil 801 and the distance detection device, the distance between the wireless charging transmitter 1 and the vehicle-mounted receiving coil 801 can be obtained. The position control device compares its preset distance with the distance detected by the distance detection device, thereby controlling the height adjustment device 10 to adjust the height of the support device 2.

[0036] In this invention, the height adjustment device 10 includes at least two height adjustment components. Each height adjustment component includes a support leg 1001, a screw 1002, and a third drive device 1003. One end of each support leg 1001 is fixedly connected to the support device 2, and the other end of each support leg 1001 is threadedly connected to a screw 1002. Each third drive device 1003 is connected to a screw 1002 and can drive the corresponding screw 1002 to rotate around its own axis. Each third drive device 1003 is signal-connected to a position control device. The third drive device 1003 causes the screw 1002 to rotate clockwise or counterclockwise, thereby causing the screw 1002 to screw into or out of the threaded hole of the corresponding support leg 1001, changing the extension length of the screw 1002, and thus changing the height of the support device 2. It should be noted that the output end of the third drive device 1003 can be directly fixedly connected to the screw 1002, or it can be connected to the screw 1002 through a transmission device, as long as it can drive the screw 1002 to rotate around its own axis.

[0037] In a preferred embodiment, the system also includes a base and three legs 1001, with the lower end of each leg 1001 rotatably connected to the base.

[0038] In a preferred embodiment, the height adjustment device 10 includes two height adjustment components, which are respectively connected to both ends of the support device 2. The heights of the two height adjustment devices 10 can be adjusted independently, so that the support device 2 can be in a horizontal or tilted state, so that the wireless charging transmitter system 1 has different tilt angles, and meets the test requirements of the wireless transmitter charging system and the vehicle-mounted receiver coil 801 under different relative tilt angles.

[0039] This invention also includes a calibration receiving module 11 and a fault analysis device 12. The wireless charging transmitting system 1 can wirelessly charge the calibration receiving module 11. The calibration receiving module 11 can be signal-connected to the fault analysis device 12, and the fault analysis device 12 can be signal-connected to the vehicle-mounted receiving module 8. The fault analysis device 12 can receive charging data from the vehicle-mounted receiving module 8 to detect the working status of the vehicle-mounted receiving module 8, including phenomena such as faults, low voltage, and low current, and to perform fault analysis. Before testing, the calibration receiving module 11 simulates and matches various parameters of the vehicle-mounted receiving module 8 of the vehicle under test to achieve the parameter state specified in the test specifications. The calibration receiving module 11 receives energy from the wireless charging transmitting system 1 to perform parameter pre-checks and verifications, and sends the test data to the fault analysis device 12. The fault analysis device 12 can generate a report on these parameters and use the report as the standard value when testing the vehicle-mounted receiving module 8. During testing, the fault analysis device 12 receives data from the vehicle-mounted receiving module 8 of the vehicle under test, compares the test data of the vehicle-mounted receiving module 8 with the test data of the calibration receiving module 11, and thus determines whether the vehicle-mounted receiving module 8 is working properly. If the value obtained when testing the vehicle deviates from the standard value and exceeds a certain indicator, it indicates that the vehicle-mounted receiving module 8 under test has a fault and needs to be repaired or adjusted.

[0040] This invention also includes a parameter adjustment module 13. The calibration receiving module 11 includes a calibration receiving coil 1101, and the parameter adjustment module 13 can be signal-connected to the calibration receiving coil 1101. The parameter adjustment module 13 can adjust the matching parameters of the calibration receiving coil 1101 according to the parameters of the vehicle-mounted receiving coil 801 of different vehicles and the parameters of the resonant system of the vehicle-mounted receiving module 8, so that the calibration receiving module 11 can reach the optimal resonance state, thereby improving the accuracy of the test.

The remote control device 14 can remotely control the testing process, preventing test personnel from being exposed to the electromagnetic fields generated during the testing process.

[0042] In a preferred embodiment, the remote control device 14 has a display function, preferably equipped with a touch screen capable of displaying information such as current, voltage curves, charging curves, coil temperature, and the temperature of key components.

The calibration control module 1103 performs power distribution, allocating the DC power converted by the calibration rectifier circuit 1102 to the calibration battery 1104. The load module consumes the power of the calibration battery 1104 to simulate the power consumption of various functional modules of the vehicle, ensuring the comprehensiveness and accuracy of the test. The load module is preferably a resistor.

[0045] In a preferred embodiment, the fault analysis device 12 is wirelessly connected to the calibration receiving module 11 and the vehicle-mounted receiving module 8; the parameter adjustment module 13 is wirelessly connected to the calibration receiving coil 1101; and the remote control device 14 is wirelessly connected to the position control device and the calibration receiving module 11.

The displacement detection device detects whether the vehicle is moving and whether any object is moving between the wireless charging transmitter system 1 and the vehicle-mounted receiving coil 801. If a metallic foreign object is present between the wireless charging transmitter system 1 and the vehicle-mounted receiving coil 801, it will cause a malfunction in the wireless power transmission. Furthermore, the metallic foreign object will be heated by the wireless charging transmitter system 1, posing a safety hazard. Therefore, when a metallic foreign object is detected, the wireless charging transmitter system 1 stops working and charging is shut off. Similarly, when the vehicle moves or an object moves between the wireless charging transmitter system 1 and the vehicle-mounted receiving coil 801, the wireless charging transmitter system 1 stops working and charging is shut off to ensure charging safety.
