Specifically, when the sunshade assembly 1 is located at the fully-closed position i of the guide rail, the sunshade assembly is in a fully-unfolded state, and the car sunroof is in a fully-sunshade state. Preferably, the fourth input signal is generated under the condition that the third control signal is output according to the third input signal so that the actuating part of the sun shade assembly extends to the mechanism blocking point part IV and retracts to the full-close position I within a fifth preset time period. Here, the setting of the fifth preset time period may be set according to actual requirements, for example, the fifth preset time period may be set to be a time less than 10s (e.g., 9s, 8s, 7s, 6s, 5 s). The second input signal, the third input signal and the fourth input signal may be signals set as required, and specifically, may be continuous signals of a preset duration.
In addition, the interaction module 4 as described above may employ a push button switch or a key switch. To provide better operability, the interaction module 4 may be provided as two switches: a first switch and a second switch.
Specifically, the first switch is configured to: and triggering a first preset time length to form a first input signal, and triggering a fourth preset time length to form a fourth input signal. For example, but not limited to, the first preset time period may be a time period greater than or equal to 10s, that is, a time period for which the first switch is continuously pressed for 10s or more than 10 s; the second preset time period may be a time period less than 10s, i.e. the second switch 9s or 8s may be continuously pressed, etc.
Wherein the second switch is configured to: triggering a second preset time length to form the second input signal, and triggering a third preset time length to form the third input signal. For example, but not limited to, the third preset time period may be a time period greater than or equal to 10s, that is, a time period for which the second switch is continuously pressed for 10s or more than 10 s; the fourth preset time period may be a time period less than 10s, i.e. the first switch 9s or 8s may be continuously pressed, etc.
It should be noted that the first preset time, the second preset time, the third preset time and the fourth preset time may be determined according to actual requirements, but it is required to ensure that the first preset time and the fourth preset time are not overlapped, and meanwhile, the second preset time and the fourth preset time are not overlapped.
Furthermore, the control module 5 may comprise a control unit and a drive unit.
