Description

Technical Field

[0001] This invention relates to the field of automotive combination switch technology, and more particularly to a column shift lever combination switch structure. Background Technology

[0002] As automotive technology matures, people are increasingly focused on the safety and comfort of driving. Traditional gear shifting is located directly on the driver's right, requiring a significant distance for the driver's right hand from the steering wheel when shifting gears. This is a drawback in terms of both safety and comfort. Therefore, more and more small cars and SUVs are incorporating column shifters below the steering wheel, often with photoelectric sensors integrated into the shifter, typically located at the top of the circuit board. However, large off-road vehicles and trucks rarely feature column shifters. Due to the harsh driving environment and high levels of dust inside these vehicles, dust can easily enter through the gaps between the shift lever and buttons, settling on the photoelectric sensor and affecting its stability. Therefore, a new combination switch with a column shifter function is needed to prevent dust from affecting the stability of the photoelectric sensor. Summary of the Invention

[0035] The principle of this invention:

[0036] Column shifter function:

[0037] When rotating block 2, it will drive block 6 to rotate at the same time. When rotating block 2 rotates to forward / reverse gear (D / N / R gear), the grating strip 601 at the lower end of block 6 rotates and non-contactly senses the photoelectric sensor 703 on the first circuit board 7. The signal is then output to the car identification module through the wires soldered on the first circuit board 7 to realize the gear shifting function.

[0038] Moving the handle up and down activates the hydraulic slow-speed (M+ / M-) gear function, while moving the handle forward and backward activates the manual transmission gear shifting function. Both functions can be achieved through the toggle switch structure at the bottom of the handle. This structure can be a common toggle switch structure on the market, so it will not be described in detail.

[0039] Manual / Automatic (A / M) switching function:

[0040] Pressing button 3 causes pressure plate 4 and conductive rubber plate 5 to be pressed down simultaneously. The conductive particles on conductive rubber plate 5 make contact with the first contact point 701 of copper foil on the first circuit board 7 and conduct electricity. The electricity is output to the vehicle identification module through the wires soldered on the first circuit board 7 to realize the manual / automatic transmission switching function. After releasing the button, button 3 will automatically reset under the rebound force of the elastic wall of conductive rubber plate 5.

[0041] Driving mode switching function:

[0042] Rotating the knob 9 causes the contact bridge 10 mounted on it to rotate simultaneously, making contact with the second copper foil contact 1101 of the second circuit board 11 and conducting. The output is sent to the vehicle identification module through the wires soldered on the second circuit board 11, realizing the function of switching driving modes (Economy mode E / P, Off, Comfort mode L1).

[0043] The invention's column shifter function, achieved through a combination switch for the car's gearshift lever, eliminates the need for a manual or automatic transmission lever on the right side of the driver's seat. Combined with a flat-floor cab, this creates a more spacious aisle. Firstly, the increased cab space makes shifting drivers more convenient, especially for high-speed drivers in China, as it allows for seamless driver changes without stopping. Secondly, shifting gears can be performed without taking your hands off the steering wheel, offering convenient and comfortable operation and minimizing distractions during driving. This allows the driver to focus more on the road, enhancing safety. This invention can be applied not only to large off-road vehicles and trucks but also to small cars and SUVs.

[0044] This invention achieves photoelectric sensing switch function by placing a photoelectric sensor at the lower end of the circuit board and cooperating with the grating strip at the lower end of the block, thus avoiding dust from falling directly on the upper end of the circuit board and affecting the stability of photoelectric sensing.

[0045] Since the upper part of the handle is equipped with button 3, top post 301 and pressure plate 4, it will occupy a large amount of internal space of the handle. The present invention sets the photoelectric sensing structure at the lower part of the first circuit board 7, which can avoid the button structure, make the internal space of the handle more compact, and make better use of the internal space of the handle.
