As shown in fig. 1, the utility model provides a take mechanical type steering wheel switch of touch-sensitive, including flush mounting plate of switch 1, electric capacity diaphragm 2, inner shell 3, circuit board 5, micro-gap switch 6, base 7 and balanced structure. The utility model discloses after driver's finger touches the electric capacity response region on the flush mounting plate of switch 1, MCU senses the appearance value change, and then the function module of discernment finger touching, and when driver finger further push down flush mounting plate of switch 1, flush mounting plate of switch 1 drive inner shell 3 downstream and trigger micro-gap switch 6 that sets up on circuit board 5, further realize controlling the function module that the finger touched.

Specifically, the capacitor diaphragm 2 is pasted on the back of the switch panel 1, the switch panel 1 is of an appearance operation structure made of a PC material, and when a driver touches a capacitor sensing area on the switch panel 1 with a finger, the MCU senses the change of a capacitance value, so as to identify a functional module touched by the finger.

Further, the inner case 3 is attached to the back side of the switch panel 1, and can move together with the switch panel 1 when the switch panel 1 is pressed. The middle part of the downside of inner shell 3 is provided with the contact, and the below of inner shell 3 is provided with circuit board 5, sets up control circuit on the circuit board 5, and the upside of circuit board 5 sets up micro-gap switch 6, and micro-gap switch 6 inserts in the control circuit on the circuit board 5 for control circuit controls. When the inner housing 3 moves downwards with the switch panel 1, the contact located in the middle of the lower side of the inner housing 3 can contact and trigger the micro switch 6.

In particular, an outer casing (not shown) is disposed between the circuit board 5 and the inner casing 3 for wrapping and fixing the circuit board 5, and is fixed on the base 7 and movably connected with the inner casing 3, so as to ensure that the outer casing keeps a static state when the inner casing 3 moves downward along with the switch panel 1. In order to further protect the circuit board 5 and the micro switch 6, waterproof rubber (not shown) is further arranged on the upper sides of the circuit board 5 and the micro switch 6, and the waterproof rubber is tightly attached to and covers the upper side surfaces of the circuit board 5 and the micro switch 6 in order to have a good waterproof effect.

In order to ensure that the inner shell 3 can successfully trigger the micro switch 6 after a finger operates any sensing area of the switch panel 1, a balance structure is arranged at the lower side of the inner shell 3. In this embodiment, the balance structure is a balance bar 4, the two sides of the lower portion of the inner shell 3 are both provided with protrusions, and the balance bar 4 is movably connected between the protrusions of the two sides. Specifically, the balance bar 4 can rotate around a shaft between the protruding portions on the two sides, the middle portion of the balance bar 4 forms an Jiong-shaped structure, the middle portion of the balance bar 4 is sleeved on a pair of slide rails of the base 7, the slide rails are arranged in parallel to the inner bottom surface of the base 7, and due to the short stroke of the micro switch 6, the rail gap of the slide rails is slightly larger than the diameter of the balance bar 4, so that when the inner shell 3 moves up and down, the middle portion of the balance bar 4 slides along the direction (the direction perpendicular to the paper surface in fig. 1) defined by the rail of the slide rails. Due to the limiting effect of the pair of sliding rails, the balance rod 4 cannot rotate around one end of the balance rod, and therefore when any position on the switch panel 1 is subjected to downward acting force, the switch panel 1 and the inner shell 3 can be driven to move downwards integrally under the limiting effect of the balance rod 4, and the microswitch 6 is triggered.

Another object of the utility model is to provide a steering wheel, including foretell mechanical type steering wheel switch of taking touch-sensitive, this steering wheel is when operational safety obtains the guarantee, and the outward appearance is succinct more pleasing to the eye, has more scientific and technological sense.

To sum up, the utility model discloses a mode that electric capacity touch and mechanical type switch mix has avoided the easy mistake of exclusive use electric capacity touch switch driver hand to touch the problem of operation promptly, has also optimized the necessary clearance between mechanical button simultaneously, can make a seamless surface, has promoted the science and technology of steering wheel switch and has felt.
