Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0033] Refer to Figures 1 - 9As shown in the figure, in an embodiment of the present utility model, a control unit for controlling the opening and closing of a rolling shutter cover is proposed, which is used to be integrated in the rolling shutter cover to control the opening and closing of the rolling shutter cover. Specifically, it includes a cover body 1 and an opening 2 formed on the cover body 1. A top cover 3 passing through the opening 2 is provided on the cover body 1. A circuit board 4 is installed on a part of the top cover 3 located on one side of the opening 2. An NFC module is integrated on the circuit board 4. A connecting wire 5 extending out of the cover body 1 is provided on the circuit board 4. At the same time, a bottom cover 6 is also provided inside the cover body 1, and the bottom cover 6 is used to press and limit the circuit board 4. Based on the cover body 1 as the integration basis of the entire switch control unit, the entire switch control unit is installed in the rolling shutter cover. Among them, the driving mechanism, control box, etc. that specifically control the opening and closing actions of the rolling shutter cover in the rolling shutter cover still adopt the original integration technology. After the circuit board 4 is integrated through the cooperation of the top cover 3 and the cover body 1, when an NF0 card or a smart device approaches the top cover 3 externally, it can generate an induction with the internal NFC module, and the generated signal is transmitted to the control unit inside the rolling shutter cover through the connecting wire 5 to achieve switch control. The signal judgment program adopted also directly uses the existing technology. The main purpose of this embodiment is to describe and protect the assembly structure of the integration unit.

[0034] After integrating the NFC function, there are multiple ways to control the opening and closing of the rolling shutter cover. In the case of forgetting to bring the key or losing the remote control transmitter, the rolling shutter cover can also be opened and closed through an NFC card or a smart device carried with you (such as a mobile phone, smart bracelet, etc.), which increases the diversity and convenience of the opening and closing methods of the rolling shutter cover.

[0035] In addition to directly using the NF0 function to achieve control, it can also be controlled through the integrated buttons. Specifically, on the flexible board 32, there are a first flexible button and a second flexible button for respectively controlling opening and closing. A first pressing button is installed in the inner cavity of the first flexible button, and a second pressing button is installed in the inner cavity of the second flexible button. The first pressing button and the second pressing button adopt common switches and are electrically connected to the circuit board 4. By pressing the first pressing button and the second pressing button, a control signal for triggering the rolling shutter cover to open or close is generated.

[0036] At the same time, induction lights are also integrated on the circuit board 4 on both sides of the first pressing button and the second pressing button. At the same time, light-transmitting patterns are set on the first flexible button and the second flexible button. On the one hand, the patterns are used to indicate the moving direction of the corresponding first pressing button and second pressing button for opening or closing the rolling shutter cover. On the other hand, they can transmit the light of the induction lights to achieve indication. For example, during the NFC induction process, it flashes to remind. When NFC induction is not used, it shows white, and when it is not matched or an error occurs, it shows blue. At the same time, it can also achieve light indication and reminder in the corresponding opening or closing state of the rolling shutter cover.

[0037] Meanwhile, as Figure 3 , Figure 4 , to avoid interference caused by the upper cover 3's induction of the NFC module, the cover body 1 includes a plastic cover 31 and a flexible plate 32 detachably installed on the plastic cover 31. That is, the flexible plate 32 and the plastic cover 31 are of a split structure, separately processed and formed and then assembled. The position of the flexible plate 32 on the plastic cover 31 corresponds to the position of the circuit board 4. The flexible plate 32 protects the circuit board 4, and the plastic and silicone materials can avoid signal shielding.

[0038] In the case of adopting a split structure, as Figure 3 , Figure 4 shown, specifically, the cover body 1 is provided with engaging holes 15 spaced apart at both ends. The upper cover 3 is provided with buckles 16 that cooperate with the engaging holes 15. Through the cooperation of the buckles 16 and the engaging holes 15, the entire upper cover 3 can be quickly installed on the cover body 1. At the same time, the upper cover 3 is provided with spaced-apart mounting posts 17. The circuit board 4 and the flexible plate 32 are locked to the mounting posts 17 through fasteners 11. That is, the circuit board 4 and the flexible plate 32 are pre-installed on the mounting posts 17 through fasteners 11 and then form an integral structure with the upper cover 3, so as to follow the upper cover 3 to be installed and disassembled relative to the cover body 1 through the cooperation of the buckles 16 and the engaging holes 15.

[0039] Of course, to ensure the overall sealing and waterproofness of the upper cover 3, the plastic cover 31 and the flexible plate 32 are of an integrally injection-molded structure. This method is an alternative to the split structure. Specifically, either of the above two implementation methods can be applied in the product.

[0040] Specifically, the flexible plate 32 is made of plastic or elastic material and has flexibility.

[0041] Specifically, after the circuit board 4 is installed, vibration avoidance and positioning are required. The cover body 1 is provided with a limiting strip 7 inside the opening 2. The circuit board 4 is provided with a limiting post 8 that abuts against the limiting strip 7. After the circuit board 4 is installed, the limiting strip 7 abuts against the limiting post 8 for positioning, and together with the limiting effect of the bottom cover 6 on the circuit board 4, the stable installation of the circuit board 4 is ensured.

[0042] Meanwhile, the cover body 1 is provided with stepped holes 9 spaced apart on both sides of the opening 2. The upper cover 3 is provided with connecting posts 10 that cooperate with the stepped holes 9. A fastener 11 for locking the connecting posts 10 is passed through the stepped holes 9. The stepped holes 9 cooperate with the connecting posts 10 during the installation of the upper cover 3 to form a preliminary positioning. After the connecting posts 10 are locked by the fasteners 11, the upper cover 3 is stably installed on the cover body 1. The fastener 11 is a screw.

[0043] Specifically, the upper cover 3 is provided with a protruding side wall 33. The side wall 33 is inserted and matched with the opening 2. The side wall 33 and the upper cover 3 enclose a groove structure 34 for accommodating the circuit board 4. By the cooperation of the protruding side wall 33 and the opening 2, the circuit board 4 is completely placed inside the cover body 1, forming a reliable protection.

[0044] Meanwhile, in order to further ensure the sealing and waterproofing of the circuit board 4, waterproof glue for sealing the circuit board 4 is filled in the groove structure 34; alternatively, a waterproof rubber ring and a waterproof cover plate are provided on the groove structure 34, and the opening edge of the groove structure 34 is sealed by the waterproof cover plate and the waterproof rubber ring, also providing waterproof protection for the circuit board 4.

[0045] The connecting wire 5 is used to connect the circuit board 4 with the control module in the rolling curtain cover. In order to facilitate the routing of the connecting wire 5 and prevent it from affecting the circuit board 4, a through hole 12 for passing the connecting wire 5 is opened on the bottom cover 6, and the connecting wire 5 is led out through the through hole 12, avoiding the situation where the connecting wire 5 presses on the circuit board 4.

[0046] Based on the above embodiments, the switch control unit is installed on the rolling curtain cover for application. As Figure 5 shown, a rolling curtain cover is specifically disclosed, which includes a side rod 13 and an aluminum alloy cover 14 installed at the end of the side rod 13. A control unit for controlling the opening and closing of the rolling curtain cover in the above embodiments is installed on the aluminum alloy cover 14. The user triggers the NFC module to generate an induction signal through the use of an NFC card or a smart device (mobile phone, bracelet) and transmits it to the control module of the rolling curtain cover to control the opening and closing of the rolling curtain cover.

[0047] In the above embodiments, by integrating the NFC module and forming a unit structure, it is convenient to integrate it into the existing rolling curtain cover. The method of adding NFC function to control the opening and closing, while still retaining the button control method, can avoid the situation where the rolling curtain cover is opened and closed when it cannot be sensed.
