However, the above-mentioned trigger structure of the window glass up-down switch is a mechanical structure, which increases the risk of button mis-touch.

Through careful analysis, the inventor of the present disclosure considers that the main reason for the above problem is that the button is rotatably connected to the panel or the bottom case, and the button has a small rotation resistance, so that the button is easily installed, and thus, when the button is touched by mistake, the window glass can be lifted or the window can be unlocked.

In view of the above, the present disclosure provides a window glass up-down switch having a touch button function, in which a partial function of the window glass up-down switch is realized by a touch button, and a risk of false triggering can be reduced by setting a trigger operation of the touch function in advance.

Specifically, the present disclosure provides a window lifter switch that generally includes a touch panel assembly, a resilient conductive key, a circuit board assembly, and a plurality of button assemblies. The touch panel assembly is provided with a touch area, touch indications are arranged in the touch area, and the touch indications correspond to different functions.

In addition, the science and technology of the car window glass lifting switch can be improved by adopting a touch key mode.

The window glass lifter switch and the vehicle provided by the present invention will be described in detail with reference to the following embodiments.

The elastic conductive key 400 is referred to as being deformable and conductive, so that the elastic conductive key 400 can sense a capacitance signal of a finger contacting the touch panel assembly 100 and transmit the capacitance signal to the circuit board assembly 300 to implement a touch operation. The elastic conductive key 400, the touch panel assembly 100 and the circuit board assembly 300 define a capacitive touch key.

By setting the working logic of the capacitive touch key, the occurrence of false touch can be avoided.

The two second lug parts 523 are located at both sides of the first lug part 522, and bottom end surfaces of the two second lug parts 523 are arranged in a coplanar manner. With the above arrangement, the rotator 520 can be engaged with the two push rods 530 and the button member 510 to make the contact portion electrically contact with the circuit board 310.

The cylindrical portion 521, the first lug portion 522, and the second lug portion 523 are integrally formed, so that the manufacturing efficiency of the rotor 520 can be improved, and the connection strength of the connection portion of the cylindrical portion 521 and the first and second lug portions 522 and 523 can be improved.

The first and second ear portions 522 and 523 are each a polygonal plate-shaped structure, for example, the first ear portion 522 is a rectangular plate-shaped structure. The second lug portion 523 comprises a horizontal section and an inclined section, and two ends of the inclined section are respectively fastened and connected with the connecting end of the horizontal section and the side wall of the column portion 521. Wherein, the bottom surface of the horizontal section contacts with the top end surface of the top rod 530.

The longitudinal section of the cylindrical portion 521 is a polygon, and for example, the longitudinal section of the cylindrical portion 521 is a polygon such as a quadrangle or a pentagon. Wherein a longitudinal section of the cylinder 521 is parallel to the length direction of the touch panel assembly 100.

The cylinder portion 521 may be rotatably connected to the upper chassis 210 through a first rotating shaft, and an axis of the first rotating shaft is perpendicular to a length direction of the touch panel assembly 100.

The two push rods 530 are disposed on both sides of the first ear portion 522, so that pushing the button member 510 forward or backward along the length direction of the touch panel assembly 100 can make the push rods 530 on both sides of the first ear portion 522 abut against the contact portions, so that the contact portions are electrically contacted with the circuit board 310.

Alternatively, referring to fig. 3 and 4, a key dome 540 is disposed between the top bar 530 and the conductive rubber plate 320, and the key dome 540 can increase the contact area between the top bar 530 and the contact portion, so as to improve the stability of the top bar 530 in matching with the contact portion.
