Technical Field

[0001] This utility model relates to the field of automotive switch technology, specifically a lever-type electric window switch. Background Technology

[0002] With the rapid rise of China's automotive industry and increasingly fierce competition both domestically and internationally, differentiation in automotive interiors, functions, and switches is receiving more and more attention in order to achieve competitive advantage. The aforementioned power window switch controls the raising and lowering of the car's doors and windows.

[0003] However, traditional switches are all button-type, which cannot meet the diverse needs of users, so they need to be improved. Utility Model Content

[0004] This utility model provides a lever-type electric window switch, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lever-type electric window switch includes a base, a PCBA mounted on the base, a conductive rubber covering the PCBA, pressure blocks on both sides of the conductive rubber, a housing fitted on the base, a button seat rotatably connected to the top of the housing, and pressure rods that cooperate with the sides of the button seat through the housing, with the lower part of the pressure rods fitting against the surface of the pressure blocks.

[0007] As a preferred embodiment of this utility model, the upper part of the outer shell is snapped onto a panel, the middle part of the panel is connected to a button base, and a button is provided in the middle of the button base.

[0008] As a preferred technical solution of this utility model, both the button and the panel are made of two-color injection molding material.

[0009] The present invention has the following advantages:

[0010] The switch adopts a lever-type button base with a matte electroplated and backlit appearance. To avoid poor backlighting due to the uniform electroplating of the material, which would affect the appearance of the switch, the internal material is made of transparent PC material to guide light, while the external material is made of ABS electroplating grade dual-color injection molding. The front is decorated with a matte electroplating and laser engraving to add working symbols, serving both an indication and aesthetic purpose. To meet the diverse needs of users, the traditional electric window switch with a handle has been replaced with a toggle-type electric window switch. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In one embodiment, see Figures 1-3 A toggle-type electric window switch includes a base 9, on which a PCBA8 is mounted. The PCBA8 is covered with conductive rubber 7, and a housing 4 is fitted over the base 9. The base 9 and housing 4 are installed together, pressing down the conductive rubber 7 and enclosing the PCBA8 to achieve a closed and protective circuit. The PCBA8 has conductive pads corresponding to the conductive rubber 7, as well as LEDs and other electrical components to provide operating indicators and backlighting for the switch. Surface mount connectors are soldered onto the PCBA8 for easy connection to the vehicle's wiring harness for functional output. When the conductive rubber 7 is compressed and its travel is sufficient, the contacts of the conductive rubber 7 touch the gold fingers of the conductive pads on the PCBA8, turning on the switch. When the external force is removed, the axial force provided by the rebound of the conductive rubber 7 causes the contacts to reset under the action of the conductive rubber 7's own elasticity, turning off the switch. The elasticity of the conductive rubber 7 provides tactile feedback and operating force. The outer casing 4 has a guide groove and a rotating shaft inside. The button seat 3 can rotate on the rotating shaft, and the pressure rod 5 can slide on the guide groove. Conductive rubber 7 and a base 9 are arranged below.

[0018] In one embodiment, pressure blocks 6 are provided on both sides of the conductive rubber 7, and a button seat 3 is rotatably connected to the top of the outer shell 4. Pressure rods 5, which cooperate with the sides of the button seat 3, are connected through the outer shell 4, and the lower part of the pressure rods 5 is in contact with the surface of the pressure blocks 6. The pressure rods 5 slide on the guide groove inside the outer shell 4. The pressure blocks 6 are arranged above the conductive rubber 7, and when pressed by the pressure rods 5, they contact the conductive rubber 7 to achieve two levels of tactile feedback. The button seat 3 has a buckle below it that engages with the button 1, a flat surface below it that contacts the pressure rods 5, and holes at both ends that allow it to rotate on a pivot in the outer shell 4.

[0019] In one embodiment, the upper part of the outer shell 4 is snapped with the panel 2, and the middle of the panel 2 is connected to the button base 3. A button 1 is disposed in the middle of the button base 3. The panel 2 is positioned above the outer shell 4 and has a matte electroplated appearance. To avoid the entire material being electroplated, affecting the switch's appearance, a two-color injection molding process is used, with one color being PC transparent non-electroplated and the other ABS electroplated, achieving an aesthetically pleasing effect. The button 1 has a matte electroplated appearance and backlight indication. To avoid the entire material being electroplated, resulting in poor backlight indication and affecting the switch's appearance, the inner part uses a single-color PC transparent material for light guidance, and the outer part uses two colors of ABS electroplated for two-color injection molding. A working symbol is added to the front using matte electroplating and laser engraving, serving both indicative and aesthetic purposes. The button 1, positioned above the button base 3, rotates with the outer shell 4 to achieve a lever-like movement.

[0020] This utility model applies to a lever-type electric window switch, which adopts a lever-type button base 3. The button 1 has a matte electroplated and backlit appearance. In order to avoid the backlight indication being poor due to the overall electroplating of a single material, which would affect the appearance of the switch, the internal material is made of PC transparent material to achieve the light guiding function. The external material is made of ABS electroplating grade two-color injection molding. The front is matte electroplated and laser engraved to add working symbols, which serve the purpose of indication and aesthetics. In order to meet the different needs of users, the traditional electric window switch is designed as a lever-type electric window switch instead of a lever-type electric window switch.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
