Description

Technical Field

[0001] The utility model relates to the technical field of automobile switches, in particular to a driving mode switch structure. Background Art

[0002] Traditional auxiliary instrument panel knob switches usually use a button plus a top column to achieve the pressing function. As the driving functions of the car increase, the space requirements for the button switch of this structure become higher and higher. To solve this problem, some manufacturers have set up a knob to achieve the driving mode switching function, but the existing knob function space utilization rate is not high, and the common knob working indicator light uses a point indicator light to light up the identification characters. The working indicator light cannot completely and evenly cover the entire character, and the aesthetics are not high; and the button logo is usually processed on the knob body, and the character pattern will rotate as the knob is turned. It is awkward for the driver or passenger to observe the knob, which affects the customer experience. Therefore, it is necessary to invent a new driving mode switch structure. Utility Model Content

[0035] Preferably, in combination with the above solution, in order to facilitate the assembly of the shaft seat 5 and the light guide seat slider 10, and to realize the gear feel function, a gear seat 6 is provided above the circuit board 8, and the gear seat 6 is fixedly connected to the housing 1.

[0036] Preferably, in combination with the above solution, in order to achieve a better gear feel when the shaft seat 5 rotates, the shaft seat 5 is sleeved on the gear seat 6 and rotatably connected to the gear seat 6. A gear groove 502 with a downward opening is provided on the inner wall of the shaft seat 5. A spring 13 is provided in the gear groove 502.

[0040] Preferably, in combination with the above solution, in order to facilitate the fixed assembly of the knob 4 and the shaft seat 5, the knob 4 is sleeved on the shaft seat 5 and fixedly connected to the shaft seat 5 by snapping.

[0041] Preferably, in combination with the above solution, to achieve better light-guiding performance, the central light guide 11 has an inverted cone-shaped structure that is larger at the top and smaller at the bottom; the side light guide 12 has an inverted L-shaped structure, with a plurality of light-guiding teeth 1201 uniformly and parallelly arranged on the lower end surface of its upper light-guiding portion 1201. This larger-at-top, smaller-at-the-bottom structure and the structure of the light-guiding teeth 1201 ensure more uniform light distribution, enhancing the aesthetically pleasing illumination of the translucent identification button 3.

[0042] Principle of this utility model:

[0043] The translucent identification button 3 features seven translucent character symbols, representing the seven driving modes: Economy, Standard, Rock, Sand, Snow, Sport, and Off-Road. The X symbol in the center of the translucent identification button 3 represents Off-Road mode. The system defaults to Economy mode each time the vehicle is powered on. A specially designed light guide allows light to illuminate the translucent character symbols on the translucent identification button 3 more evenly and broadly, enhancing their aesthetic appeal. The switch also features a circular decorative cover 2 that snaps onto the outer casing 1, concealing the internal components while maintaining aesthetic appeal.

[0044] When the knob 4 is rotated by hand, the shaft seat 5 will be driven to rotate (the translucent identification button 3 will not rotate), and the grating teeth 501 at the bottom of the shaft seat 5 will cut the light in the U-shaped photoelectric switch 803 (grating), and the number of clockwise or counterclockwise cutting times is judged to determine whether the corresponding driving mode function is triggered.

[0045] When the light-transmitting identification button 3 is pressed downward by hand, the light guide seat slider 10 and the light guide body will slide downward together. The pressing boss 1003 at the lower end of the light guide seat slider 10 first contacts the elastic conductive particles on the conductive rubber plate 7, and then contacts the pressing contact 801 to turn on the off-road driving mode function.
