[0027] The utility model discloses a handwriting pen wireless charging test system. Figures 1-2 The utility model discloses a handwriting pen wireless charging test system.

[0028] As Figure 1 Indicated, the utility model embodiments provide handwriting pen wireless charging test system includes test fixture 1, tension test device 2 and program control power 3. Test fixture 1 has guide portion 111 and fixed part 12. Guide portion 111 is suitable for terminal equipment 4 on it along the first direction sliding, make terminal equipment 4 can approach or far away fixed part 12. Tension test device 2 is fixed in fixed part 12, for connecting handwriting pen 5, and in the case where terminal equipment 4 far away fixed part 12, test handwriting pen 5 and terminal equipment 4's adsorption. Handwriting pen 5 and program control power 3 electric connection. In the case where terminal equipment 4 approaches fixed part 12, terminal equipment 4 can be adsorbed with handwriting pen 5 connection. Program control power 3 is used for carrying out current tension test to handwriting pen 5.

[0029] Among them, terminal equipment 4 can be flat, learning machine or notebook etc. the electronic equipment that can be adapted handwriting pen. Terminal equipment 4 and handwriting pen 5 usually are through magnetic attraction force adsorption.

[0030] Specifically, terminal equipment 4 has first position and second position relative to fixed part 12, and terminal equipment 4 moves along guide portion 111 between the first position and the second position. When terminal equipment 4 moves from the first position to the second position, handwriting pen 5 can be automatically adsorbed to terminal equipment 4, and current tension test can be carried out. When terminal equipment 4 moves from the second position to the first position, terminal equipment 4 will take handwriting pen 5 away from fixed part 12 until handwriting pen 5 is separated from terminal equipment 4, and tension test device 2 measures the tension of handwriting pen 5 at the moment of separation from terminal equipment 4, which represents the adsorption force between handwriting pen 5 and terminal equipment 4.

[0032] Step one, wireless charging Q value calibration is carried out to obtain basic width value data. Specifically, the resonant capacitor of the charging circuit is charged to a set voltage by using pulse voltage, and the LC resonant circuit is self-excited to oscillate. The oscillation energy gradually decreases as the energy disappears, and the change of the oscillation energy is detected and calculated within a certain period. Among them, the number of effective pulses in self-oscillation is detected by using a digital counter, and the peak value envelope is sampled by using a peak value detector for calculation.

[0033] Step two, the terminal device 4 is moved to the second position through the guide part 111, and the stylus 5 is adsorbed on the terminal device 4. The width value increment is calculated by the change of the stylus 5 itself Q value. Among them, the relevant key parameter is the bandwidth Band Width (BW@3dB attenuation), and the resonant frequency calculation formula of the LC oscillation circuit is: When the LC value changes, the LC decreases, the frequency f increases, and the pulse width in the corresponding period will decrease, and the width value data decreases. The stylus end Q value increment is fixed, and when the TX resonant circuit of the terminal device 4 has an abnormality, the stylus end Q value tested will be abnormal, and then it is judged whether the whole machine function is abnormal.

[0034] Step three, start power test, the stylus 5 is pulled by the program-controlled power supply 3 according to different charging current. The stylus end firmware contains charging strategy, and the charging current is adjusted according to the voltage of the program-controlled power supply 3. For example, the program-controlled power supply 3 supports 3C and 1C different current gear pressure test, and the stylus end charging current is obtained. After the test is completed, the test result is fed back to the terminal device 4 by the stylus 5, and the test result is displayed on the terminal device 4. When the stylus end charging current is within the range of plus or minus 10% of the target current within the set time (such as 30 min), it is judged that the test is passed. This process can be tested for a short time to judge the stability of wireless charging, or tested for a long time to judge the reliability of wireless charging.

[0035] Step four, stop charging, pull the terminal device 4, and make the terminal device 4 away from the fixed part 12. The adsorption force of the terminal device 4 on the stylus 5 is tested by the pulling force testing device 2. In the process of pulling the terminal device 4, the pulling force borne by the pulling force testing device 2 gradually increases, and the maximum pulling force is measured by the pulling force testing device 2 when the terminal device 4 and the stylus 5 are separated. The maximum pulling force is within the set range, and the adsorption capacity is judged to pass.

When testing, first, terminal equipment 4 is moved to the position close to fixed part 12, and the current tension test of handwriting pen 5 is carried out through program control power 3, and the stability and reliability of handwriting pen 5 wireless charging are tested, then terminal equipment 4 is pulled away from fixed part 12, and the adsorption capacity of handwriting pen 5 and terminal equipment 4 is tested through tension test device 2. The handwriting pen wireless charging test system can test the stability and reliability of handwriting pen 5 wireless charging, and can objectively test the actual adsorption capacity of handwriting pen 5.

[0037] As Figure 2 Indicated in the utility model embodiment, the number of orientation 111 and tension test device 2 is multiple, and multiple orientation 111 and multiple tension test device 2 are set one by one.

For example, one program control power 3 has 2 channels, and two handwriting pen 5 can be provided for current tension test.

[0039] Further, the number of program control power 3 is multiple.
