Detailed implementation manners

[0019] To make the objectives, features and advantages of the present utility model more apparent and understandable, the following provides a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Please refer to Figures 1-6 , the present utility model provides an automobile fuel-saving switch, which includes a housing 3 and a rear cover 4 that are snap-fitted together, and a face cover 2 is snap-fitted to the upper ends of the housing 3 and the rear cover 4. A support shaft 5 is installed on the inner wall of the rear cover 4, and an adjustment knob 1 is sleeved on the support shaft 5 so that the adjustment knob 1 can rotate relative to the housing 3 and the rear cover 4. A limit plate 6 is installed at the end of the support shaft 5 through a screw 7, and the limit plate 6 is used to limit the sliding of the adjustment knob 1 along the axial direction of the support shaft 5.

[0023] It should be noted that a notch is provided on the face cover 2 for adjusting the protrusion of the adjustment knob 1, so that the adjustment knob 1 can partially protrude into the external environment. A mode indicating needle is provided on the outer surface of the face cover 2, and a mode label is provided on the outer surface of the adjustment knob 1. Different energy-saving modes are selected by rotating the mode label on the adjustment knob 1 to the position of the mode indicating needle. In this embodiment, the mode labels provided on the outer surface of the adjustment knob 1 include the English letters "E", "S", and "P". When the English letter "E" is rotated to correspond to the mode indicating needle, it indicates that the engine economy gear working mode is selected, and "S" and "P" respectively indicate that the engine standard gear working mode and the engine power gear working mode are selected. Thus, it can be seen that in this application, by rotating the adjustment knob 1, multiple energy-saving modes can be selected. Compared with the ECO button that can only select a single fuel-saving mode, it is beneficial to improve the fuel-saving effect.

[0024] A slide rail 8 and a protruding block 13 are provided on the rear cover 4, and a plurality of V-shaped grooves 9 are provided in the slide rail 8. A steel ball 11 is embedded on the side of the adjustment knob 1 close to the rear cover 4, and the steel ball 11 is adapted to the V-shaped groove 9. The steel ball 11 is connected to the adjustment knob 1 through a spring 12, and a sliding groove 14 that slidably cooperates with the protruding block 13 is provided on the adjustment knob 1. A through groove 15 is further provided on the adjustment knob 1, and a metal conductive sheet 16 is clamped in the through groove 15. The metal conductive sheet 16 extends toward the side close to the housing 3 and protrudes out of the through groove 15, and a PCB circuit board 19 is provided on the housing 3. A resistance guide rail 20 that cooperates with the metal conductive sheet 16 is provided on the side of the PCB circuit board 19 close to the adjustment knob 1.

[0025] It should be noted that after the adjustment knob 1 is rotated, since the metal conductive sheet 16 is clamped on the adjustment knob 1, it will drive the metal conductive sheet 16 to slide to different positions on the resistance guide rail 20 of the PCB circuit board 19, thereby changing the resistance value. The PCB circuit board 19 outputs different electrical signals to the vehicle engine controller according to the resistance value, so that the vehicle engine can flexibly adjust the working parameters of the engine, freely select the fuel-saving mode according to different road conditions and load capacities, and make the engine always operate in the best fuel-saving state. It can be understood that when the metal conductive sheet 16 slides to different positions on the resistance guide rail 20, the corresponding steel ball 11 slides into different V-shaped grooves 9. Through the mutual cooperation of the steel ball 11, the V-shaped groove 9, the slide rail 8, and the spring 12, the state of the adjustment knob 1 is kept stable, thereby preventing the adjustment knob 1 from accidentally rotating.

[0026] It should be further noted that through the mutual cooperation of the protruding block 13 and the sliding groove 14, the adjustment knob 1 can only rotate within a certain angle range to avoid the steel ball 11 sliding out of the slide rail 8; correspondingly, the adjustment knob 1 can only rotate the mode label to the position of the mode indicating needle, and cannot rotate other positions of the adjustment knob 1 to the position of the mode indicating needle.

[0027] Optionally, the letter "ESP" is engraved on the face cover 2. An LED backlight 17 is installed at one end of the PCB circuit board 19 close to the face cover 2. At night, the letter "ESP" on the face cover 2 can be illuminated by the LED backlight 17. A signal connection terminal 18 is installed at the bottom end of the PCB circuit board 19, and the signal connection terminal 18 is used to send the electrical signal output by the PCB circuit board 19 to the vehicle engine controller.
