Description

Technical Field

[0001] This invention relates to the field of automotive switch technology, and in particular to a connection structure for automotive micro switches. Background Technology

[0002] In automobile manufacturing, microswitches are commonly used for on / off control. However, existing microswitches only provide on / off control and lack analog signal output capability. For example, when a continuous resistance signal is required from the microswitch, a printed circuit board needs to be added to the switch assembly. The analog output is achieved through the circuit board's conversion. Furthermore, the switch terminals and connector terminals are typically physically connected by wires, and the connector terminals are secured to the pre-set mounting positions in the plastic housing using a snap-fit ​​structure. However, the aforementioned existing technical solutions have the following significant drawbacks: 1. The addition of circuit boards directly increases material costs. At the same time, the soldering process between the circuit board and the terminals, and the connection process between the wires and the terminals, all increase production process costs and labor assembly costs. 2. The circuit board and connecting wires require a lot of internal space, making it difficult to miniaturize the overall structure of the switch and thus unable to meet the current layout requirements of "compact and lightweight" automotive interior components. 3. Continuous vibration during vehicle operation can easily cause the connection between the wire and the terminal to loosen, and the terminal structure that is fixed by the clip is prone to loosening and displacement, which in turn can cause abnormal signal transmission and affect the reliability of the switch adjustment function. 4. The large number of parts such as circuit boards, wires, and clips, combined with complex assembly processes, significantly reduces the assembly efficiency of mass production and is not conducive to large-scale manufacturing.

[0003] Therefore, how to enable automotive microswitches to have analog signal output capabilities, while maintaining a simple, compact, and highly stable overall structure, is a technical problem that researchers in this field urgently need to solve. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automotive micro switch connection structure that has the ability to output analog signals, and has a simple, compact overall structure and high stability.

[0005] The objective of this invention is achieved through the following technical solution: A micro switch connection structure for automobiles includes: a pressing assembly, a switch terminal assembly, a resistor assembly, and a plug-in assembly. The pressing assembly includes a switch positioning seat and a pressing trigger module, the pressing trigger module being disposed on the switch positioning seat. The switch terminal assembly includes a switch common terminal, a switch output terminal, and a switch connection terminal, the switch common terminal, the switch output terminal, and the switch connection terminal being respectively spaced apart on the switch positioning seat. The connecting portion of the pressing trigger module is connected to the switch common terminal, and the trigger end of the pressing trigger module is located between the switch output terminal and the switch connection terminal. The resistor assembly includes a first resistor and a second resistor, the first resistor being connected to both the switch common terminal and the switch connection terminal, and the second resistor being connected to both the switch output terminal and the switch connection terminal. The plug-in assembly includes a first plug-in and a second plug-in, the first plug-in being connected to the switch common terminal, and the second plug-in being connected to the switch output terminal.

The reset spring is disposed on the switch positioning seat, the press lifting slider is connected to the reset spring, the trigger spring is disposed on the press lifting slider, the connecting part of the trigger spring slides through the switch common terminal, and the trigger end of the trigger spring is located between the switch output terminal and the switch connection terminal.

[0007] In one embodiment, the connecting portion of the trigger spring is provided with a connecting hole, and the connecting hole is slidably connected to the common terminal of the switch.

[0008] In one embodiment, the switch positioning base is provided with a positioning post, and the reset spring is sleeved on the positioning post.

[0021] Combination Figure 1 , Figure 2 and Figure 3 As shown, an automotive micro switch connection structure 10 includes: a pressing assembly 100, a switch terminal assembly 200, a resistor assembly 300, and a plug-in assembly 400. The pressing assembly 100 includes a switch positioning seat 110 and a pressing trigger module 120, with the pressing trigger module 120 disposed on the switch positioning seat 110. The switch terminal assembly 200 includes a switch common terminal 210, a switch output terminal 220, and a switch connection terminal 230, which are respectively spaced apart on the switch positioning seat 110. The connecting portion of the pressing trigger module 120 is connected to the switch... The switch common terminal 210 is connected, and the trigger end of the press trigger module 120 is located between the switch output terminal 220 and the switch connection terminal 230; the resistor assembly 300 includes a first resistor 310 and a second resistor 320, the first resistor 310 is connected to the switch common terminal 210 and the switch connection terminal 230 respectively, and the second resistor 320 is connected to the switch output terminal 220 and the switch connection terminal 230 respectively; the plug assembly 400 includes a first plug 410 and a second plug 420, the first plug 410 is connected to the switch common terminal 210, and the second plug 420 is connected to the switch output terminal 220.

[0022] It should be noted that the switch positioning base 110 is used to install and fix various components, and the press trigger module 120 is used to switch the overall switch structure on and off. Specifically, the connecting part of the press trigger module 120 is connected to the switch common terminal 210, and the trigger end of the press trigger module 120 is located between the switch output terminal 220 and the switch connection terminal 230, so that different resistance value signals can be switched by pressing. Further, the switch common terminal 210 is used to connect to the input power supply, the switch output terminal 220 is used to output analog resistance value signals, and the first resistor 310 is connected to both the switch common terminal 210 and the switch connection terminal 230, and the second resistor 320 is connected to both the switch output terminal 220 and the switch connection terminal 230. In this way, different analog resistance value signals can be switched by the press trigger module 120 contacting the switch output terminal 220 and the switch connection terminal 230 respectively. For example, when the press-triggered module 120 is in its initial state, its trigger terminal is set to abut against the switch output terminal 220. At this time, current enters from the switch common terminal 210 and flows from the press-triggered module 120 to the switch output terminal 220. The analog resistance signal output by the switch output terminal 220 is the first resistance signal. When the press-triggered module 120 is pressed, causing its trigger terminal to separate from the switch output terminal 220, the trigger terminal is now located between the switch output terminal 220 and the switch connection terminal 230. Current enters from the switch common terminal 210 and flows through the first resistor 310 and the second resistor 320 to the switch output terminal 220. At position 0, the analog resistance signal output by switch output terminal 220 is the second resistance signal. When the trigger end of the press trigger module 120 descends to contact the switch connection terminal 230, current enters from the switch common terminal 210, passes through the first resistor 310 and the second resistor 320, and is output from the switch output terminal 220. Simultaneously, current also flows from the press trigger module 120 to the switch connection terminal 230, then through the second resistor 320 to the switch output terminal 220. At this time, the analog resistance signal output by switch output terminal 220 is the third resistance signal. Thus, the automotive micro switch connection structure 10 can switch between three analog resistance signal outputs, thereby broadening its applicability in the automotive field. Furthermore, the first connector 410 is connected to the switch common terminal 210, and the second connector 420 is connected to the switch output terminal 220. This allows for plug-in connections instead of wire connections, making the installation and use of the overall switch structure more convenient. The automotive micro switch connection structure 10 of the present invention, by providing a pressing assembly 100, a switch terminal assembly 200, a resistor assembly 300, and a plug-in assembly 400, has the following advantages: 1. By setting a first resistor 310 and a second resistor 320 between the switch common terminal 210, the switch output terminal 220 and the switch connection terminal 230, analog signal output can be achieved without using a circuit board connection. This reduces the overall material cost and simplifies the production and installation process, thereby reducing the overall production process cost and labor cost. Furthermore, the structure without using a circuit board and connecting wires can effectively optimize the installation space, making the overall structure more compact and thus better suited to the current layout requirements of "compact and lightweight" automotive interior components. 2. By setting the first connector 410 and the second connector 420 to replace the connection method of wires and terminals in the prior art, the overall structure is more stable, thereby making the signal output more stable.

[0023] In one implementation method, combined with Figure 2 and Figure 3 As shown, the press trigger module 120 includes a press lifting slider 121, a trigger spring 122, and a reset spring 123. The reset spring 123 is disposed on the switch positioning seat 110. The press lifting slider 121 is connected to the reset spring 123. The trigger spring 122 is disposed on the press lifting slider 121. The connecting part of the trigger spring 122 slides through the switch common terminal 210. The trigger end of the trigger spring 122 is located between the switch output terminal 220 and the switch connection terminal 230.

[0024] It should be noted that the connecting part of the trigger spring 122 is provided with a connecting hole, which is slidably connected to the switch common terminal 210. This allows the trigger spring 122 to slide up and down under the pressing operation of the lifting slider 121, and to complete the connection operation with the switch common terminal 210. Specifically, when the reset spring 123 is in the initial state, the trigger end of the trigger spring 122 is set to abut against the switch output terminal 220. At this time, the second connector 420 outputs a first resistance signal. When the lifting slider 121 is pressed, the trigger end of the trigger spring 122 separates from the switch output terminal 220. At this time, the second connector 420 outputs a second resistance signal. When the lifting slider 121 is pressed, causing the trigger spring 122 to descend to the switch connection terminal 230 and abut against it, the second connector 420 outputs a third resistance signal, thereby completing the switching operation of the switch analog output signal. In one embodiment, a positioning post 111 is provided on the switch positioning base 110, and the reset spring 123 is sleeved on the positioning post 111. In this way, the reset spring 123 can be installed and fixed, making the overall structure more stable.

A first mounting post is provided on the first connector block 412, and the first mounting post is detachably connected to the first mounting hole. In this embodiment, the first mounting hole is a threaded hole, and the first mounting post is threaded.

[0028] It should be noted that the first plug-in terminal 411 can be connected to the switch common terminal 210 by soldering, resistance welding, or laser welding, thereby improving the overall structural strength. Simultaneously, the first plug-in terminal 411 can be fixed to the corresponding mounting plastic housing using an encapsulation process, further enhancing the overall structural strength. The first plug-in block 412 is used to connect with external components. A first mounting hole is provided at the bottom of the first plug-in terminal 411, allowing the first plug-in block 412 to be detachably connected to the first plug-in terminal 411 via a first mounting post. This allows the first plug-in block 412 to be replaced according to different usage scenarios, thus adapting to the connection operations of different components. In this embodiment, the first mounting hole is a threaded hole, and the first mounting post is threaded. Thus, the first plug-in block 412 can be installed on the first plug-in terminal 411 via a threaded connection, allowing the first plug-in block 412 to be replaced according to different usage scenarios, thereby adapting to the connection operations of different components.

A second mounting post is provided on the second connector block 422. The second mounting post is detachably connected to the second mounting hole.

[0030] It should be noted that the second plug-in terminal 421 can be connected to the switch output terminal 220 by soldering, resistance welding, or laser welding, thereby improving the overall structural strength. Simultaneously, the second plug-in terminal 421 can be fixed to the corresponding mounting plastic housing using an encapsulation process, further enhancing the overall structural strength.
