Description

Technical Field

[0001] The utility model relates to a switch, in particular to a one-button start switch for a passenger vehicle which can prevent accidental touching. Background Art

[0002] The one-button start switch is a car start switch structure that has emerged in recent years. You only need to press the one-button start button in the car to start or shut down the engine, replacing the traditional key-insertion start and shut-down structure, making it easier to operate and providing a better user experience. At present, the one-button start switch on the market generally uses a single-point or double-point synchronous press-sensing structure for signal input. The defect of this structure is that during driving, the one-button start switch may be accidentally touched. At this time, pressing the switch may cause the vehicle to shut down, seriously affecting the safe driving of the vehicle. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a one-touch start switch for a passenger car to prevent accidental touching and to solve the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A one-button start switch for a passenger car to prevent accidental touching, characterized in that it includes an outer shell, a button block is movably arranged in the outer shell, the top of the button block is connected to a button cover, and the bottom of the button block is downwardly extended with a first pressure column and a second pressure column, and an elastic rubber sleeve and a press sensing chip are sequentially arranged below the corresponding button block in the outer shell, the elastic rubber sleeve is provided with an elastic upper convex portion cooperating with the first pressure column, the bottom of the elastic upper convex portion is provided with a first pressure block that can cooperate with a first press receiving end on the press sensing chip, first steps and second steps are provided on both sides of the bottom of the second pressure column, and a damping block cooperating with the first step and the second step is provided on the press sensing chip, and the bottom of the second pressure column can squeeze the second press receiving end on the press sensing chip, and when the button block is pressed, the first pressure column is first squeezed with the elastic upper convex portion, and then the first and second steps on the second pressure column are squeezed with the damping block.

[0006] A guide strip is extended from the outer side wall of the button block, and a guide groove for inserting the guide strip is arranged in the outer shell.

[0007] The side wall of the button upper cover is provided with a first positioning groove and a first clamping groove, and the pressing block is provided with a first positioning strip matched with the first positioning groove and a first clamping block matched with the first clamping groove.

[0008] An annular groove is provided at the bottom of the button block, a waterproof step which can extend into the annular groove is provided inside the outer shell, and a drainage groove is provided on the outer wall of the outer shell at a position corresponding to the waterproof step.

[0009] The above technical solution is a one-touch start switch for a passenger car that prevents accidental touching. By setting the first and second pressure columns on the button block, and respectively cooperating with the elastic upper protrusion and the damping block, when the button block is pressed, the first pressure column is first squeezed with the elastic upper protrusion, and then the first and second steps on the second pressure column are squeezed with the damping block, so that the two-level damping pressing of the button block can be realized to finally realize the signal input, which can effectively reduce the situation where the accidental touching of the button block affects the normal driving of the vehicle, and further improve the safety of vehicle driving.

[0016] As shown in the figure, the utility model disclosed in the present invention includes an outer shell 3, a button block 7 is movably arranged in the outer shell 3, a guide strip 10 is extended from the outer wall of the button block 7, and a guide groove 24 for inserting the guide strip 10 is arranged in the outer shell 3 to guide the movement of the button block 7. The top of the button block 7 is connected to the button cover 1, and the side wall of the button cover 1 is provided with a first positioning groove 8 and a first card slot 6. The button block 7 is provided with a first positioning strip 9 matched with the first positioning groove 8, and a first card slot 25 matched with the first card slot 6, so as to facilitate the positioning and card installation of the button cover 1. A decorative outer ring 2 is also carded at the top of the outer shell 3 corresponding to the button block 7 to increase its aesthetics, and a plug-in seat 5 is carded at the bottom of the outer shell 3 for positioning and plugging of the switch as a whole. A first pressure column 15 and a second pressure column 21 are extended downward from the bottom of the button block 7, and an elastic rubber sleeve 12 and a press sensing chip 18 are sequentially arranged below the corresponding button block 7 in the outer shell 3. The elastic rubber sleeve 12 is provided with an elastic upper protrusion 11 that cooperates with the first pressure column 15, and the bottom of the elastic upper protrusion 11 is provided with a first pressure block 16 that can cooperate with the first press receiving end 17 on the press sensing chip 18. The bottom of the second pressure column 21 is provided with a first step 22 and a second step 23 on both sides, and the press sensing chip 18 is provided with a damping block 19 that cooperates with the first step 22 and the second step 23. The bottom of the second pressure column 21 can squeeze the second press receiving end 20 on the press sensing chip 18. When the button block 7 is pressed, the first pressure column 15 is first squeezed with the elastic upper protrusion 11, and then the first and second steps on the second pressure column 21 are squeezed with the damping block 19. An annular groove 13 is provided at the bottom of the button block 7, and a waterproof step 14 is provided inside the outer shell 3 which can extend into the annular groove 13. A drainage groove 4 is provided on the outer wall of the outer shell 3 at a position corresponding to the waterproof step 14. When liquid enters the outer shell through the gap between the button block 7 and the outer shell 3, it will gradually flow to the waterproof step 14 and be discharged outward through the drainage groove 4 without entering the internal electrical components, thereby effectively improving its waterproof performance.

[0017] The working principle of the utility model is: when it is necessary to control the start or shutdown of the engine, by pressing the button block 7, the button block 7 moves, and its first pressure column 15 first squeezes the elastic upper protrusion 11 and moves downward. At this time, the damping force applied to the button block 7 is relatively small. As the button block continues to move and press, the first and second steps on the second pressure column 21 will squeeze the damping block 19. At this time, the damping force applied to the button block 7 becomes larger until the first pressure block 16 presses the first pressing receiving end 17 and the second pressure column 21 presses the second pressing receiving end 20. At this time, the button block 7 is pressed into place, and the two pressing receiving ends are squeezed and feedback information is given to control the start or shutdown of the engine.

[0018] The structure of the utility model can realize two-level damping feedback during the button pressing process. The button is pressed deeper, and the pressing force in the case of a general accidental touch is smaller. Due to the damping effect, the button will not be pressed into place at once, avoiding the transmission of accidental touch signals, and can effectively reduce the situation where the accidental touch button block affects the normal driving of the vehicle, thereby further improving the safety of vehicle driving.
