[0003] Since the reaction force of the micro switch acts on the inclined surface of the conical hole, the operating force required to move the slider 1 is greater than the design target value; the holding force of the slider 1 in four directions is provided by the positive pressure of the micro switch, which cannot keep the slider 1 rigid enough, and the slider 1 shakes a lot; when the operating stroke of the micro switch is fixed, the operating stroke required to slide the slider 1 is large; only one micro switch is designed, and it is impossible to ensure that the operating force in four directions is the same, which does not meet the design target. Therefore, previous products could not reach the design target values ​​in terms of operating force and operating stroke, and the operating feel of the slider 1 in the toggle direction could not be kept consistent with other operating parts (PUSH button).

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1 and Figure 2 The automobile central control command switch shown includes a PCB board 10, a bracket 8 arranged on the PCB board 10, a toggle assembly arranged in the bracket 8, an inner shaft 17 arranged in the toggle assembly for sliding in the Z direction (up and down direction), and a knob assembly arranged at the upper end of the inner shaft 17. The bracket 8 is cylindrical and extends along the Z direction. The PCB board 10 is located at the lower end of the bracket 8. The axis of the inner shaft 17 extends along the Z direction and is perpendicular to the PCB board 10.

[0035] like Figure 1 As shown, the PCB board 10 is provided with four conductive rubbers 9 which are evenly arranged around the inner shaft 17. The upper end of the conductive rubber 9 abuts against a first push rod 18 which is arranged in the bracket 8 and slides in the Z direction. The first push rod 18 extends along the Z direction, and the sliding inclined surface 20 on the toggle assembly is arranged one-to-one with the first push rod 18.

[0036] like Figure 5 As shown, each sliding slope 20 extends radially outward and upward along the inner shaft 17. Under the action of the elastic force of the conductive rubber 9, the upper end of the first push rod 18 abuts against the sliding slope 20 opposite thereto. The bracket 8 is provided with a radial reset structure for resetting the toggle assembly after being toggled. When the toggle assembly is toggled, the push rod is pushed downward along the Z direction by the sliding slope 20 and output to the PCB board 10 through the conductive rubber 9. After the toggle assembly is released, the toggle assembly can be reset under the action of the radial reset structure.

[0037] In order to realize the upper limit positioning of the first push rod 18, the first push rod 18 is set to have a tapered structure with a small top and a large bottom. The bracket 8 is provided with a tapered hole that matches the first push rod 18. When the conductive rubber 9 is in the reset state, the tapered hole positions the first push rod 18 upward. In order to reduce friction, the upper end of the first push rod 18 is a spherical surface, which is in point contact with the sliding inclined surface 20.

[0038] like Figure 1 and Figure 2 As shown, the toggle assembly includes an orientation ring 7 disposed in a bracket 8 and slidable in the Y direction (front-back direction) and an toggle seat 6 disposed in the orientation ring 7 and slidable in the X direction (left-right direction), and the inner shaft 17 is slidably disposed in the toggle seat 6 in the Z direction. Specifically, there are four sliding inclined surfaces 20, two of which are relatively disposed on both sides of the orientation ring 7 in the Y direction, and the other two sliding inclined surfaces 20 are relatively disposed on both sides of the toggle seat 6 in the X direction.

[0039] The Z direction is the axial direction of the inner shaft 17, the X and Y directions are the radial directions of the inner shaft 17, and the X direction is perpendicular to the Y direction. When the directional ring 7 slides along the Y direction, the sliding inclined surface 20 provided on the directional ring 7 squeezes the first push rod 18 opposite thereto, so that the first push rod 18 moves downward along the Z direction; when the toggle seat 6 slides along the X direction, the sliding inclined surface 20 provided on the toggle seat 6 squeezes the first push rod 18 opposite thereto, so that the first push rod 18 moves downward along the Z direction.

[0040] like Figure 1 and Figure 2As shown, the radial reset structure includes two first micro switches 21 arranged between the bracket 8 and the directional ring 7 and two second micro switches 16 arranged between the directional ring 7 and the toggle seat 6. The two first micro switches 21 are relatively arranged on both sides of the directional ring 7 in the Y direction, and the two second micro switches 16 are relatively arranged on both sides of the toggle seat 6 in the X direction.

[0041] When the directional ring 7 slides along the Y direction, one of the first micro switches 21 is compressed and deformed, and when the external force disappears, the first micro switch 21 resets the directional ring 7. When the toggle seat 6 slides along the X direction, one of the second micro switches 16 is compressed and deformed, and when the external force disappears, the second micro switch 16 resets the toggle seat 6.

[0042] like Figure 1 As shown, the bracket 8 is provided with a first mounting groove, and the first micro switch 21 is installed in the first mounting groove. The directional ring 7 is provided with a second mounting groove, and the second micro switch 16 is installed in the second mounting groove. The first mounting groove is provided to facilitate the installation of the first micro switch 21, and can effectively prevent the first micro switch 21 from falling off. The second mounting groove is provided to facilitate the installation of the second micro switch 16, and can effectively prevent the second micro switch 16 from falling off.

[0043] like Figure 1 and Figure 2 As shown, a third micro switch 22 is provided on the PCB board 10, and a second push rod 19 that slides in the Z direction and is provided in the bracket 8 abuts against the third micro switch 22, and the upper end of the second push rod 19 abuts against the inner shaft 17. When the Z direction is pressed, the inner shaft 17 moves downward along the Z direction, pushing the second push rod 19 to move downward, and the output is sent to the PCB board 10 through the third micro switch 22. When the external force of pressing disappears, the third micro switch 22 resets the inner shaft 17.

[0044] The upper end of the second push rod 19 is a spherical surface, and the second push rod 19 is in point contact with the inner shaft 17. When the inner shaft 17 moves along the X and Y directions, the friction between the second push rod 19 is small.

[0045] like Figure 2 As shown, the lower end of the second push rod 19 has a limit stop edge, and the portion of the bracket 8 that guides the second push rod 19 is provided with a limit step. When the third micro switch 22 is in the reset state, the limit stop edge abuts against the limit step.

[0046] like Figure 3 and Figure 4As shown, the knob assembly includes a gear seat 3 sleeved on the upper end of the inner shaft 17 and a knob 2 arranged on the gear seat 3. The inner end of the gear seat 3 is circumferentially distributed with a plurality of gear slots. The side of the inner shaft 17 has a mounting hole. The mounting hole is provided with a radially extending gear pin 13. The gear pin 13 is inserted into the gear slot under the action of the spring 14. When the knob 2 is rotated, the gear pin 13 is retracted in the gear slot by the spring 14 with the inner shaft 17 as the fixed end, so as to realize the rotation feel output.

[0047] like Figure 2 As shown, a support 12 is provided at the upper end of the inner shaft 17 , a touch PCB 11 is provided on the support 12 , and a touch panel 1 connected to the touch PCB 11 is provided on the knob 2 .

[0048] During installation, install the shift pin 13 and the spring 14 into the mounting hole of the inner shaft 17, and make the shift pin 13 cooperate with the shift slot, assemble the support 12 and the touch PCB 11 on the inner shaft 17, and then assemble the touch panel 1 and the knob 2 on the shift seat 3 to form the knob 2 subassembly.

[0049] The second micro switch 16 is installed into the directional ring 7 through the buckle 15, and then the directional ring 7 and the toggle seat 6 are assembled to form the toggle seat 6 sub-assembly, and then the toggle seat 6 sub-assembly is installed on the bracket 8 through the sliding cover plate 5 and the fixed bracket 84, and then the knob 2 sub-assembly is installed into the toggle seat 6 sub-assembly.

[0050] During the toggle operation, the toggle seat 6 and the directional ring 7 move, directly pressing the four micro switches located in the circumferential direction (two first micro switches 21 and two second micro switches 16). The corresponding micro switches provide the reset force, eliminating the deviation caused by the transmission ratio. The operating force and operating stroke can reach the designed target values, and the operating feel is consistent with other operating parts (PUSH button).

[0051] The toggle operating force F is composed of the reaction force of the first micro switch 21 / the two second micro switches 16, the gravity of the action part, and the sliding friction between the action part and the directional ring 7. Through theoretical and practical tests, it can meet the design target value.

[0052] Toggle operation stroke S: The holding force of the knob 2 in four directions is provided by the positive pressure of four micro switches (two first micro switches 21 and two second micro switches 16). The four micro switches are evenly distributed in four directions, and the toggle operation force in the four directions is exactly the same. The positive pressure keeps the knob 2 sufficiently rigid and the knob 2 shakes less. When the operation strokes of the four micro switches are fixed, the toggle direction operation stroke S can also meet the design target value.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
