Technical Field

The utility model relates to the field of automobile switches, in particular to a touch-pressing automobile electric window switch.

Background technique

The car electric window switch is an indispensable switch structure in the car interior. The car electric window switch arranged on the main driver's side mainly has four door lifting and door lock functions. The traditional car electric window switch is a plurality of physical buttons that move independently. The structure switch has many internal parts, complex structure and high manufacturing cost. With the development of automobile electrification, touch buttons are increasingly used in car interior switches due to their good aesthetics. The realization of functions through partial touch and press can effectively reduce the number of parts inside the switch and reduce the manufacturing cost of the switch. However, due to the large cover of the car electric window switch, partial touch and press of the cover will cause uneven force on the cover. Pressing one side downward will cause the switch to partially tilt or the cover to become stuck downward, affecting the normal function realization and operation feel of the switch. Therefore, it is necessary to adjust the switch structure to ensure that when partial pressing is performed, the cover can move vertically downward as a whole to ensure the reliability of operation.

Detailed ways

Embodiment, as shown in Figures 1 to 5, a touch-press type automobile electric window switch comprises a base 1, a circuit board assembly 2 and a conductive rubber 3 arranged on the base 1, a housing 4 fixedly connected to the base 1, and a cover 5 arranged on the housing 4 and movable up and down, wherein the cover 5 is fixedly connected to an inner housing 6 that moves up and down with the cover 5. Two dial buttons 9 are arranged side by side on the housing 4, and the dial buttons 9 are rotatably mounted on the housing 4 through a pin shaft. A group of touch components are arranged below the cover 5, and the conduction of the touch component signal can be realized by touching the corresponding area on the cover 5. The automobile electric window switch structure greatly simplifies the internal structure of the switch through the combination of the touch button and the dial button 9, reduces the number of parts, facilitates the arrangement and installation, and effectively reduces the cost of the switch.

Specifically, the internal matching structure of the switch is as follows: a left top rod 14 and a right top rod 15 are respectively provided on both sides of the dial button 9, and a second conductive rubber column 32 and a third conductive rubber column 33 are respectively provided on the conductive rubber 3, which are respectively connected with the left top rod 14 and the right top rod 15, and the dial button 9 is turned to control the lifting and lowering of the electric window.

The front part of the cover 5 is provided with a central door lock switch touch area 16 and a child lock switch touch area 17, and the rear part of the cover 5 is provided with a front and rear window switching touch area 18. The front and rear window control is switched by touching and pressing the front and rear window switching touch area 18, and then the dial button 9 is turned to control the lifting of the front window or the rear window; a touch component is provided under the touch area. In order to achieve contact and conduction between the touch component and the circuit board component 2, a group of conducting reeds 11 corresponding to the touch component are provided on the inner shell 6, and a signal transmission lead 12 is provided between the conducting reed 11 and the circuit board component 2. The touch component is connected to the circuit board component 2 through the conducting reed 11 and the signal transmission lead 12. In order to synchronously realize the reset function of the cover 5, the signal transmission lead 12 is preferably a spring. In order to facilitate the installation of the spring, a round hole 62 for placing the spring is provided on the inner shell 6, and the spring is placed in the round hole 62.

The conductive rubber 3 is provided with a first conductive rubber column 31, and the first conductive rubber column 31 is provided with a first push rod 13. The upper end of the first push rod 13 acts on the inner shell 6, and the surface cover 5 drives the inner shell 6 to move downward, and the inner shell 6 drives the first push rod 13 to move downward, so that the first conductive rubber column 31 is deformed and contacts and conducts with the circuit board assembly 2.

When the central door lock switch touch area 16, the child lock switch touch area 17, and the front and rear window switch touch area 18 are touched on the surface of the cover, the signal is transmitted to the chip on the circuit board assembly 2 through the conductive reed and spring between the cover and the inner shell, and the chip determines the recognized functional area according to the signal source. While touching, the cover is pressed down, and the cover drives the inner shell to move downward, driving the first push rod 13 to move downward, so that the first conductive rubber column 31 is deformed and contacts the circuit board assembly 2 for conduction, realizing the corresponding function.

Since the surface cover 5 has a large area, local pressing may cause the surface cover to tilt up or get stuck downward, affecting normal use. For this reason, it is necessary to improve the switch structure to ensure that when any area of the surface cover 5 is pressed, the surface cover 5 can move vertically downward without getting stuck. Specifically, a group of vertical guide grooves 61 are provided on the outer wall of the inner shell 6, and preferably, vertical guide grooves 61 are provided on all four surfaces. A group of vertical guide ribs 41 cooperating with the vertical guide grooves 61 are provided on the inner wall of the outer shell 4, and the direction of movement of the surface cover 5 is ensured by the vertical guide ribs 41 moving up and down in the vertical guide grooves 61. In order to avoid the vertical guide ribs 41 getting stuck with the vertical guide grooves 61 when the vertical guide ribs 41 are locally pressed, a first balance bar 7 and a second balance bar 8 arranged perpendicular to each other are also provided in the inner shell 6, and the first balance bar 7 and the second balance bar 8 are rotatably mounted on the inner shell 6. Furthermore, the first balance bar 7 and the second balance bar 8 are crankshaft structures, with a straight bar section in the middle and crank sections at both ends. The housing 4 is provided with limit cards 42 for limiting the swing of the straight bar sections of the first balance bar 7 and the second balance bar 8 respectively.

When any area of the cover 5 is touched and pressed, the first balance bar 7 and the second balance bar 8 rotate, so that the cover 5 and the inner shell 6 move downward as a whole, thereby avoiding problems such as the switch tilting or getting stuck caused by only one side moving downward.

The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
