The heart rate module 400 is used for detecting a heart rate value of a human body, the heart rate module 400 comprises a light emitting part 410 and a receiving part 420, the light emitting part 410 emits light towards the skin of the human body, the light is reflected to the receiving part 420 through human tissue, and the heart rate value of the user is obtained through signal processing. The present invention provides a testing mechanism for testing the performance of the heart rate module 400.
In the embodiment of the present invention, as shown in fig. 1 to 4, the testing mechanism includes a testing assembly 100, a light shielding member 200, and an adjusting assembly.
The testing assembly 100 comprises a mounting seat 110 and a testing circuit 120, the heart rate module 400 is arranged on the mounting seat 110, and the testing circuit 120 is electrically connected with the heart rate module 400; the light blocking member 200 is positioned between the light emitting part 410 and the receiving part 420; the adjusting assembly is connected with the light shielding member 200 and drives the light shielding member 200 to move so as to adjust the width of the light shielding member 200.
It can be understood that, when the heart rate module 400 detects the heart rate of the human body, the light emitting part 410 emits light towards the skin of the human body, and reflects the light to the receiving part 420 through the human tissue, and in order to prevent the light emitted by the light emitting part 410 from directly emitting to the receiving part 420 without passing through the human body, the light shielding part 200 can be arranged between the light emitting part 410 and the receiving part 420 through the light shielding part, so that the light emitted by the light emitting part 410 is directly emitted to the receiving part 420, and the accuracy of detecting the heart rate by the heart rate module 400 is ensured.
In this embodiment, the testing assembly 100 includes a mounting base 110 and a testing circuit 120, the mounting base 110 is used for fixing the heart rate module 400, and the testing circuit 120 is electrically connected to the heart rate module 400, so as to implement a performance test on the heart rate module 400. Meanwhile, by arranging the adjusting assembly, the adjusting assembly is connected with the light shielding piece 200 to adjust the width size of the light shielding piece 200, namely, adjust the blocking width between the light emitting part 410 and the receiving part 420, so that the performance test of the heart rate module 400 under the application of the light shielding pieces 200 with different widths is realized, the optimal width of the light shielding piece 200 applied to the heart rate module 400 is determined, and the performance of the heart rate module 400 is improved.
It is understood that the specific structural shape of the light shielding member 200 may be determined according to actual situations, such as a strip structure, a column structure, or other special-shaped structures. In this embodiment, in consideration of the structural limitation of the heart rate module 400 itself, the gap between the light emitting portion 410 and the receiving portion 420 is small, and alternatively, the light shielding member 200 may have a strip-shaped or linear structure to adapt to the compactness of the whole structure of the heart rate module 400. In practice, the light-shielding member 200 functions to shield light, and a dark color setting, such as black, dark blue, dark purple, etc., can be adopted. In this embodiment, the light shielding effect of the light shielding member 200 is related to the width dimension of the light shielding member 200, and when the width dimension of the light shielding member 200 is larger, the light shielding effect is better, but when the width dimension of the light shielding member 200 is larger, the size structure of the heart rate module 400 is increased, so that the heart rate module 400 using the light shielding members 200 with different widths can be tested to determine the width of the light shielding member 200, and on this basis, in order to achieve the adjustability of the width of the light shielding member 200, the light shielding member 200 can be made of a material with plasticity, such as silica gel, rubber, and the like. Optionally, in this embodiment, the light shielding member 200 is a black silicone strip.

By arranging the adjusting component and the light shielding member 200, the light shielding member 200 is positioned between the light emitting part 410 and the receiving part 420 of the heart rate module 400 to prevent the light emitted by the light emitting part 410 from being directly irradiated to the receiving part 420; the adjusting assembly can adjust the shading width of the shading piece 200 to realize the function of testing the performance of the heart rate module 400 by changing the width dimension of the shading piece 200, so that the optimal width of the shading piece 200 applied to the heart rate module 400 can be determined, and the performance of the heart rate module 400 is improved.
