Detailed Description
The present utility model will be described in further detail with reference to examples and drawings, but embodiments of the present utility model are not limited thereto.
The specific implementation process of the utility model is as follows:
As shown in fig. 1 to 3, an ultra-thin type hand-sweeping door contact sensor switch of a cabinet lamp comprises a metal shell 1, a spacer 2 and an FPCB circuit board 3, wherein the spacer 2 is sleeved in the metal shell 1, the FPCB circuit board 3 is arranged below the spacer 2, an electronic component 31, an infrared emitter 32 and an infrared receiver 33 are mounted on the upper surface of the FPCB circuit board 3, the infrared emitter 32 and the infrared receiver 33 are sheet-shaped, the infrared emitter 32 and the infrared receiver 33 are arranged at intervals, the spacer 2 is used for isolating the infrared emitter 32 and the infrared receiver 33, and the spacer 2 is made of EVA foam. Specifically, the FPCB circuit board 3 is a flexible circuit board, and the flexible circuit board has better flexibility and plasticity, so that the structural layout of the inductive head switch is more compact and reasonable, the thickness of the FPCB circuit board 3 is small, the ultrathin design of the cabinet lamp controller is more convenient to realize, the volume of a product is reduced, the weight is reduced, the installation on a laminate of a cabinet is convenient, and the assembly and wiring of the electronic component 31 are more flexible and convenient. The infrared emitter 32 and the infrared receiver 33 are both sheet-shaped and welded or adhered on the FPCB circuit board 3, so that the cabinet controller realizes an ultra-thin design. The metal shell 1 is 0.3mm in thickness, is manufactured in a stamping mode, is simple in manufacturing process and low in production cost, is made of metal materials, and effectively improves the overall texture of products. The design of the isolating piece 2 is used for isolating the infrared emitter 32 and the infrared receiver 33, preventing mutual interference of signals between the infrared emitter 32 and the infrared receiver, avoiding the problem that misoperation occurs or an external signal cannot be detected correctly, and preventing an external light source from interfering the infrared receiver to influence the normal operation of the cabinet lamp induction switch. The material of the isolation piece 2 adopts EVA foam cotton, which not only can play a role in isolating the infrared emitter 32 and the infrared receiver 33, but also can be used for filling and supporting between the FPCB circuit board 3 and the metal shell 1, the EVA foam cotton has the hardness of 65 degrees, has good elasticity, can play a certain buffering role, and reduces the impact of external force on the internal electronic components 31. The thermoplastic material can be directly injection molded or foamed into products with various shapes and sizes after being heated and plasticized, and the process of opening a die and then producing the product is not needed as the conventional plastic product, so that the design is simple and the product is good; compared with the prior art, the black plastic shell is isolated, so that a plastic mould is omitted, the production cost is lower, and the weight is light. Since most cabinet door panels are dark in color, the infrared light emitted by the infrared emitter 32 is emitted or absorbed, so that the infrared receiver 33 cannot receive the effective reflected light, and it is difficult to accurately determine the opening and closing state of the cabinet door. The EVA foam is black in color, avoiding the possibility that infrared light may be absorbed or reflected as it passes through non-target objects, thereby interfering with the proper operation of the infrared receiver 33. Because the black material has strong absorption capacity to infrared light, the black EVA foam cotton can effectively reduce the interference. Thereby improving the sensitivity and response speed of the infrared receiver 33 and enabling the infrared receiver to adapt to door panels with different materials and different colors.
In the embodiment of the present utility model, the infrared emitter 32 and the infrared receiver 33 are disposed away from the board side of the FPCB wiring board 3. In order to make the infrared emitter 32 and the infrared receiver 33 have a certain distance from the board edge of the FPCB circuit board 3, and the color of the FPCB circuit board 3 is black, so that the interference caused by the reflection of the side board is effectively reduced. Specifically, when the FPCB circuit board 3 is assembled with the metal casing 1, the induction heads of the infrared emitter 32 and the infrared receiver 33 are too close to the side plates, and the side plates may reflect or absorb a part of the infrared light, so that the infrared signal received by the infrared receiver 33 is weakened, and thus erroneous judgment is caused or a correct signal cannot be detected. The black FPCB circuit board 3 is adopted, infrared rays are not reflected from the surface of the FPCB circuit board 3, but are absorbed, interference of an external light source on infrared communication is reduced, and reliability of the infrared communication is improved.
In the embodiment of the present utility model, the lower surface of the FPCB circuit board 3 is connected with a reinforcing steel sheet 4, and the reinforcing steel sheet 4 is connected with the metal casing 1. Specifically, the reinforcing steel sheet 4 is tightly attached to the FPCB circuit board 3 with a thickness of 0.3mm, and the reinforcing steel sheet 4 serves as a bottom shell and wraps the spacer 2 and the FPCB circuit board 3 inside the metal shell 1 together with the metal shell 1. The electromagnetic shielding is formed by the metal shell 1 and the reinforced steel sheet 4, so that external electromagnetic interference and radiation interference are effectively prevented from entering the inside, electromagnetic waves generated by internal equipment can be prevented from being outwards diffused, induction head reading errors or misoperation caused by the electromagnetic interference are avoided, and the interference capability of the equipment is improved.
In the embodiment of the utility model, the upper surface of the metal shell 1 is provided with a through hole matched with the infrared emitter 32 and the infrared receiver 33, the infrared emitter 32 and the infrared receiver 33 can interact with external environment or targets through the through hole 11, and the infrared emitter 32 and the infrared receiver 33 are effectively protected from the external environment. The shape and size of the through hole 11 corresponds to the shape and size of the infrared emitter 32 and the infrared receiver 33. The design of the through holes may be set depending on the size and shape of the infrared emitter 32 and the infrared receiver 33.
In the embodiment of the utility model, the upper surface of the FPCB circuit board 3 is provided with the fixing block 34, the fixing block 34 and the FPCB circuit board 3 are integrally formed, the side surface of the fixing block 34 is provided with the groove 35, and the groove 35 is used for placing the FPCB flexible flat cable 5. Specifically, the infrared receiver 33 of the present utility model is separated from the circuit of the control board, and the signal lines connecting the infrared receiver and the control board are connected by using the 1.0 mm-pitch 8Pin FPCB flexible flat cable 5 for connecting and transmitting signals. The connection mode of the FPCB backward-turning type terminal is adopted between the control board and the control board, so that the connection is easy to realize, the circuit connection process can be simplified, and the signal interference can be avoided. The FPCB flexible flat cable 5 is inserted into the groove 35, and the back surface of the FPCB flexible flat cable 5 is coated with adhesive, so that the FPCB flexible flat cable is adhered to the cabinet layer plate, and the position of a circuit is fixed. The back adhesive is directly adhered to the laminate of the cabinet, the laminate is not required to be drilled with long-row layers, and the installation is very convenient. According to different door panels and different materials, on-site installers can easily debug the door panels. Subsequent maintenance and upgrades are also very convenient.
The working principle of the utility model is as follows: the power supply stabilizes the voltage to 5V through a 78L05 voltage stabilizer and supplies power to the MCU. The singlechip outputs an infrared modulation signal and emits the infrared modulation signal through an infrared emission tube 32. The shielding object appears in the range of 0.1 CM to 5CM, the modulated infrared light is reflected back through the shielding object and is received by the infrared receiver 33, the infrared receiver 33 sends the received signal to the singlechip for decoding, and after the singlechip decodes the determined signal, the TTL level signal is output to the induction head switch to control the switch of the cabinet lamp.
