[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In one embodiment, see Figure 1-Figure 4 A steering wheel switch with a push button comprises a base 13, a housing 6 is detachably connected to the base 13, a button seat 5 is arranged in the middle of the housing 6, a button 3 is arranged on the button seat 5, a lever seat 4 is arranged on both sides of the button seat 5, and a lever 1 is arranged on the lever seat 4. The base 13 is installed with the housing 6 to achieve the closure and protection of the switch. The housing 6 is provided with rib grooves and buckles, so that the button seat 5 and the lever seat 4 can rotate smoothly inside. The base 13 is installed with the housing 6, and wraps the PCBA 11 to achieve the closure and protection of the switch. The PCBA 11 is arranged with a conductive disk corresponding to the conductive rubber 10 to provide backlight for the switch. The PCBA 11 is welded with a wiring harness assembly 14, which is convenient for connection with the vehicle body wiring harness sheath to achieve functional output.

[0020] In one case of the present embodiment, the dial button 3 is fixedly connected with the dial button seat 5, and the dial button seat 5 is arranged on the rotating shaft inside the shell 6. When the dial button 3 is pressed down, the dial button seat 5 is driven to press the conductive rubber 10, and the switch is turned on. The dial button 3 is made of PC and PC+ABS double-color injection molding to prevent the appearance surface from shrinking. The dial button 3 is equipped with anti-misalignment ribs and card slots, which cooperate with the ribs and buckles of the dial button seat 5 to ensure the integrity with the dial button seat 5 to prevent misassembly and fall off. The dial rod 1 is equipped with anti-misalignment ribs and card slots, which cooperate with the ribs and buckles of the dial rod seat 4 to ensure the integrity with the dial rod seat 4 to prevent misassembly and fall off. The dial button seat 5 has a rotating shaft structure that cooperates with the shaft hole of the shell 6, so that the dial button seat 5 will not have the risk of shaking or falling out in the shell 6, so that it can slide smoothly on the shell 6. The lever seat 4 has a rotating shaft structure that cooperates with the shaft hole of the housing 6, so that the lever seat 4 will not have the risk of shaking or falling out in the housing 6, and can slide smoothly on the housing 6.

[0021] In one case of the present embodiment, a PCBA 11 is provided on the base 13, and the surface of the PCBA 11 is covered with a conductive rubber 10. The conductive rubber 10 is installed on the PCB board, and the rubber pressure head is interference fit with the top rod. When the dial button 3 or the dial rod 1 is turned, the dial button seat 5 or the dial rod seat 4 drives the rubber to press down, and when the stroke is satisfied, the particles or pot pieces of the conductive rubber 10 act on the PCB board, thereby connecting. When the external force is removed, the contact is reset under the action of the self-rebound force of the conductive rubber 10, and the elastic force of the conductive rubber 10 provides the feel and operating force of the switch. The PCBA 11 is equipped with electrical components such as pot pieces and LEDs to provide backlight and functions for the switch. A wiring harness assembly 14 is welded on the PCB, which is convenient for connection with the vehicle body wire speed sheath to achieve functional output.

[0022] In one case of this embodiment, the housing 6 is slidably connected with a short push rod 7, a sheet push rod 8 and a long push rod 9 that cooperate with the conductive rubber 10. The short push rod 7 has a guide rib structure that cooperates with the guide groove of the housing 6, so that the short push rod 7 will not have the risk of shaking or coming out in the housing 6, so that it can slide smoothly on the housing 6. The long push rod 9 has a guide rib structure that cooperates with the guide groove of the housing 6, so that the long push rod 9 will not have the risk of shaking or coming out in the housing 6, so that it can slide smoothly on the housing 6. The sheet push rod 8 has a guide rib structure that cooperates with the guide groove of the housing 6, so that the sheet push rod 8 will not have the risk of shaking or coming out in the housing 6, so that it can slide smoothly on the housing 6.

[0023] In one case of this embodiment, a wiring harness assembly 14 is welded on the PCBA 11. The wiring harness assembly 14 realizes functional output. The connector hook on the wiring harness assembly 14 is connected to the vehicle body wire speed sheath to prevent the wiring harness sheath from falling out.

[0024] In one case of this embodiment, the surface of the housing 6 is snapped with a cover 2, and the housing 6 is connected to the base 13 by screws 12. The cover 2 is provided with anti-error ribs, which cooperate with the anti-error grooves of the housing 6. Fastening is achieved by snap assembly to prevent falling off. The surfaces of the dial button 3, the lever 1, and the cover 2 can be painted and laser engraved or painted and pad printed to add work symbols.

[0025] like Figure 4 Shown

[0026] 1: When in the initial state, the conductive rubber 10 is in a pre-compression state, and the conductive particles and the conductive disk are open-circuited.

[0027] 2: When the dial button 3 is turned along the rotation axis, the dial button seat 5 is driven to rotate in the housing 6. When the movement corresponds to the switch stroke, the button is stopped by the maximum limit of the rubber. At this time, the conductive rubber 10 particles are connected to the conductive disk on the PCBA11 to realize the output of the corresponding switch function signal.

[0028] 3: When the external force is removed, the conductive rubber 10 provides a rebound force to reset the button. The conductive rubber 10 provides the operating force and operating feel. At this time, the conductive rubber 10 rebounds to the initial state, and the conductive particles and the conductive disk are open.

[0029] 4: Press the dial button 3 to directly drive the long push rod 9, the conductive rubber 10 is compressed, the rubber particles are connected to the conductive disk on the PCBA11, and the corresponding function signal of the switch is output.

[0030] 5: When the external force is removed, the rubber provides a rebound force to reset the button. The conductive rubber 10 provides the operating force and operating feel. At this time, the conductive rubber 10 rebounds to the initial state, and the conductive particles and the conductive disk are open.

[0031] The utility model is suitable for a steering wheel switch with a push button. Compared with other steering wheel switches, more functions can be integrated in the same space. The button 3 can be toggled or pressed, and the operation feel is rich. The button 3 and the lever 1 are painted with imitation electroplating silver paint, which reduces the cost compared with traditional electroplating.
