[0025] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0026] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a portable signal trigger component 100, comprising a housing 1, a circuit board 3 installed in the housing 1, and at least one control module.

[0027] See also Figure 2 In this embodiment, the housing 1 is flat as a whole. Preferably, the overall thickness of the housing 1 does not exceed 5 mm. If the thickness of the adhesive is not considered, the thickness can be controlled to be less than 3 mm, so that the portable signal trigger component 100 is light and thin as a whole. Specifically, a receiving cavity is formed in the housing 1; the circuit board 3 and the control module are arranged in the receiving cavity; the circuit board 3 is attached to the bottom of the receiving cavity; and the control module is close to the top of the receiving cavity. The control module is a module that controls the conduction or disconnection of the circuit.

[0028] The material of the shell 1 can be soft, for example, the material of the shell 1 is a soft rubber material such as silicone. The soft shell 1 covers and penetrates the control module and the circuit board 3. In this way, the control module can also be operated or pressed through the soft shell 1, so as to control the circuit to be turned on or off. However, this embodiment does not limit the material of the shell 1. Preferably, the control module can be partially exposed from the shell 1. In this way, the overall design of the product can be applicable to shells 1 of different hardness and softness materials.

[0029] See also Figure 3In a specific embodiment, the housing 1 includes an upper shell 11 and a bottom shell 12, and the upper shell 11 and the bottom shell 12 are assembled together to form the whole of the housing 1. For example, the upper shell 11 and the bottom shell 12 are connected together by ultrasonic welding. Specifically, a receiving cavity is formed between the upper shell 11 and the bottom shell 12. The upper shell 11 is provided with a through groove 111 connected to the receiving cavity. The circuit board 3 and the control module are arranged in the receiving cavity; the circuit board 3 is close to the bottom shell 12. Preferably, the circuit board 3 is a flexible printed circuit board; the circuit board 3 is closer to the bottom shell 12 to keep the overall housing 1 lighter and thinner, and can be closer to the sensing area of ​​the smart terminal.

[0030] See also Figure 2 Preferably, the surface of the receiving cavity for mounting the circuit board 3 is a flat surface. Figure 3 As shown, the inner surface of the bottom shell 12 is a flat surface. More preferably, the outer surface of the bottom shell 12 is a flat surface. In this way, a magnetic suction piece is provided on the inner surface or the outer surface of the bottom shell 12, so that the portable signal trigger component 100 can be adsorbed to the external smart terminal through the magnetic suction piece. In an alternative connection method, an adhesive piece can also be provided on the outer surface of the bottom shell 12, and attached to the external smart terminal through the adhesive piece. In this way, the overall portability of the product is achieved.

[0031] See also Figure 3 and Figure 4 In this embodiment, the circuit board 3 is provided with a coil 30, a chip 40 and a switch circuit. The chip 40 and the coil 30 form a series circuit through the switch circuit.

[0032] Preferably, the coil 30 is disposed near the bottom of the bottom housing 12. The coil 30 surrounds the chip 40 and serves as an antenna of the chip 40; the coil 30 is used to transmit information signals sent by the chip 40. The switch circuit is located outside the coil 30.

[0033] The control module includes a switch 50 (such as Figure 4 ) and extended key 52 (as shown Figure 2 and Figure 3 As shown). A portion of the extended button 52 is exposed from the through slot 111. In this embodiment, when the switch element 50 is not pressed, the switch circuit is in an off state. The extended button 52 is used to press the switch element 50 to turn on the switch circuit so that the chip 40 and the coil 30 are connected in series.

[0034] See also Figure 3 In this embodiment, the extension button 52 is a mechanical button, and the switch 50 is a pot-shaped button; the pot-shaped button is correspondingly arranged directly below the mechanical button. In this way, when the mechanical button is pressed, the pot-shaped button can be pressed.

[0035] In an alternative solution, the control module may also be an electronic switch, a capacitive switch, an inductive switch, etc.

[0036] See also Figure 4 In a specific embodiment, the chip 40 includes a first chip and a second chip. The switch circuit includes a first switch circuit and a second switch circuit, which are respectively used to form a first series circuit and a second series circuit between the first chip, the second chip and the coil 30. The switch element 50 of the control module includes a first switch element and a second switch element, which respectively control the first switch circuit and the second switch circuit. In this way, the first control module turns on the first switch circuit, so that the first chip and the coil 30 form a first series circuit; the information signal set by the first chip is transmitted through the coil 30 to generate a first electronic tag; the first electronic tag is sensed and read by the NFC (Near Field Communication) module of the smart terminal. However, it should be noted that only one switch circuit is allowed to be turned on and generate an electronic tag at the same time. Similarly, the second control module turns on the second switch circuit, so that the second chip and the coil 30 form a second series circuit; the information signal set by the second chip is transmitted through the coil 30 to generate a second electronic tag; it is sensed and read by the NFC module of the smart terminal.

[0037] See also Figure 5 In other embodiments, the plurality of chips 40 form a corresponding number of series circuits with the coil 30 through a corresponding number of switch circuits; and a corresponding number of switch elements 50 control the corresponding number of switch circuits of the chips 40 .

[0038] See also Figure 6 In another specific embodiment, the plurality of chips 40 are respectively connected by corresponding numbers Switching Electric The circuit forms a corresponding number of series circuits with the coil 30; through a switch element of the control module 50 selectively controls the switch circuits corresponding to the number of chips 40. For example, single-clicking the switch 50 controls the switch circuit where the first chip and the coil are located; double-clicking the switch 50 controls the switch circuit where the second chip and the coil are located; single-clicking the switch 50 and holding it for 5 seconds controls the switch circuit where the third chip and the coil are located; when the switch 50 is not pressed, the switch circuit where any chip and the coil are located is disconnected, etc.

[0039] It should be noted that the overall shape of the housing 1 can be various. No specific limitation is made to the shape of the housing 1 or the overall shape of the portable signal trigger component 100. For example, the portable signal trigger component can be triangular, square, rectangular, circular, elliptical or hexagonal.
