[0016] The following is a detailed description of a vehicle door handle switch controlled by a transistor, with reference to the accompanying drawings.
[0017] Combined with appendix Figure 1-3 This invention will be described in detail below.
[0018] A vehicle door handle switch controlled by a transistor includes a push-button switch 1 and a transistor 2;
[0019] The first pin of push button switch 1 is connected to the first current limiting resistor 3 and then to the positive terminal of the power supply. This is used to provide the current required for push button switch 1 to work and to limit the current to prevent circuit damage.
[0020] The second and third pins of push-button switch 1 are both unused and do not participate in the circuit connection.
[0021] The fourth pin of push-button switch 1 is connected to the base of transistor 2. When the button is pressed, the fourth pin is connected to the first pin, so that the base of transistor 2 receives a trigger signal.
[0022] The positive terminal of the power supply is connected to the collector of transistor 2 after the second current-limiting resistor 4, which provides the working voltage for transistor 2 and limits the current through the second current-limiting resistor 4;
[0023] The emitter of transistor 2 is connected to the negative terminal of the power supply, forming a complete circuit loop.
[0024] Furthermore, the push-button switch 1, transistor 2, first current-limiting resistor 3, and second current-limiting resistor 4 are all soldered onto the circuit board 5, forming a compact and stable electronic circuit structure that facilitates installation and maintenance.
[0025] Furthermore, the first current-limiting resistor 3, the second current-limiting resistor 4, and the emitter of the transistor 2 are all connected to the power supply via connectors, which facilitates the disassembly and replacement of the circuit and improves the flexibility of the circuit.
[0026] As a preferred embodiment, the circuit board 5 is provided with fixing holes 6, which facilitates fixing the circuit board 5 to the door handle and ensures the stability and reliability of the switch.
[0027] The specific implementation process of this utility model, a vehicle door handle switch controlled by a transistor, is as follows:
[0028] When the button of push-button switch 1 is not pressed, the current flows from connector CON1 through the first current-limiting resistor 3 (R1). Since the button is in the open state, the current cannot reach the base of transistor 2 (Q1) through the button. At this time, transistor 2 (Q1) is in the cut-off state, and the collector and emitter are equivalent to an open circuit. No current flows through the load in the circuit, which can be used in conjunction with other automotive circuits to control the door lock closing.
[0029] When the button is pressed, the first and fourth pins of the push-button switch 1 are connected. After passing through the first current-limiting resistor 3 (R1), the current can reach the base of the transistor 2 (Q1) through the button. At this time, current flows into the base, and the base of the transistor 2 (Q1) receives a trigger signal. The transistor 2 (Q1) is turned on, and the current can form a circuit from the connector CON1 through the first current-limiting resistor 3 (R1), the push-button switch 1, the second current-limiting resistor 4 (R2), and the collector and emitter of the transistor 2 (Q1). This circuit can be used in conjunction with other automotive circuits to control the door lock opening.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
