DETAILED DESCRIPTION

[0034] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0037] like Figure 1-12 As shown, an integrated knob includes a shell 1 and a PCB board 2, and also includes a knob assembly, the knob assembly includes a knob inner shell 5, a planar motion assembly is provided on the outer side of the knob inner shell 5, the planar motion assembly includes a planar motion body 4, the planar motion body 4 includes a central circular tube portion 41 and a circumferential disk portion 42, the central circular tube portion 41 is a hollow structure, the central circular tube portion 41 is buckled to the outside of the knob inner shell 5 and slides relatively, and a pressing assembly is provided below the knob inner shell 5.

[0038] Four trapezoidal platforms 7 are evenly arranged on the bottom surface of the circumferential disk portion 42. The symmetrical trapezoidal platforms 7 are grouped in pairs. The inclined surface of each trapezoidal platform 7 is facing away from the central circular tube portion 41. A push rod 8 is arranged below the inclined surface of each trapezoidal platform 7. The top of each push rod 8 includes a matching surface 81. The matching surface 81 is parallel to the inclined surface of the trapezoidal platform 7 above it, so that the matching area after the matching surface 81 contacts the inclined surface of the trapezoidal platform 7 is maximized, and the pressure on the push rod 8 is minimized, so as to avoid excessive wear of the push rod 8 so that the knob action feedback is not timely.

[0039] Each push rod 8 is slidably connected to the housing 1 via a telescopic spring. A first micro switch 9 is provided at the bottom of each push rod 8 . Each push rod 8 can slide in the direction of pressing the first micro switch 9 .

[0040] By utilizing the inclined surface of the trapezoidal platform 7 to contact the push rod 8, the planar motion of the planar moving body 4 is transmitted to the direction of pressing the first micro switch 9, so that the knob triggers the switch to obtain feedback after the planar motion. At the same time, the space under the upper circumferential disk part 42 is utilized to make the integrated structure more compact, further reducing the space occupied by the knob, and the telescopic spring is used to reset the push rod 8 to avoid the first micro switch 9 being triggered by pressure all the time.

[0041] The bottom of the circumferential disk portion 42 is slidably connected to the shell 1 via a guide body 6. The guide body 6 and the shell 1 slide relative to a straight line formed by a group of trapezoidal stages 7, and the circumferential disk portion 42 and the guide body 6 slide relative to a straight line formed by another group of trapezoidal stages 7.

[0042] By setting the guide body 6, the plane moving body 4 can be moved back and forth in four directions relative to the shell 1, and the direction is controlled in the four directions indicated by the two straight lines formed by each group of trapezoidal stages 7, so that the moving direction corresponds to the position of the trapezoidal stages 7, the action and the feedback correspond, and the two straight lines formed are perpendicular to each other, so that the plane moving action is not easily confused and causes misoperation.

[0043] The knob assembly also includes a knob bracket 3 with an overall ring structure and a knob 11 fixed to the outer surface of the knob bracket 3. The knob 11 includes a button cover and a button ring. The button ring is processed with patterns to increase the friction coefficient of the surface of the knob 11 to facilitate the rotation of the knob 11. The button cover can prevent dust and other debris from falling into the inside of the knob.

[0044] The knob bracket 3 and the knob inner shell 5 are rotationally connected by a bearing 12, and the knob bracket 3 is installed on the outside of the knob inner shell 5 through the bearing 12. A gear ring 15 and a rotating ring 16 are provided between the knob bracket 3 and the knob inner shell 5. The gear ring 15 and the knob inner shell 5 are fixedly connected by a snap-fit ​​manner, and the rotating ring 16 and the knob bracket 3 are fixedly connected by a snap-fit ​​manner. The knob bracket 3 includes a detection part 31 with an annular grille structure.

[0045] The PCB board 2 can be fixedly arranged on the top of the knob inner shell 5. The PCB board 2 is electrically connected with a sensor 21. The sensor 21 can be a photoelectric sensor. The detection part 31 is arranged at the detection end of the photoelectric sensor.

[0046] When the knob 11 is rotated, the knob bracket 3 is driven to rotate, so that the detection part 31 passes between the detection ends of the photoelectric sensor, and feedback control of the knob rotation is achieved by capturing and transmitting the light signal.

[0047] The outer wall of the gear ring 15 has a wavy structure, and two spring pieces 17 with protrusions are clamped on the rotating ring 16. The protrusion of each spring piece 17 abuts against the depression of the outer wall of the gear ring 15. By utilizing the cooperation between the spring piece 17 and the gear ring 15, when the knob is turned, the spring piece 17 rotates accordingly, and the gear ring 15 is fixed at the same time. The protrusion of the spring piece 17 deforms back and forth with the wavy outer wall of the gear ring 15, so that the rotation action is subject to a certain resistance, thereby facilitating the control of the rotation angle of the knob and improving the feel of turning the knob.

[0048] The pressing assembly includes a fixed seat 13 with a hollow structure and a sliding head 14 slidably connected to the inner cavity of the fixed seat 13. A second micro switch 10 is provided inside the fixed seat 13. A telescopic spring is fixedly connected between the sliding head 14 and the fixed seat 13. The top of the sliding head 14 abuts against the bottom surface of the knob inner shell 5, and the bottom of the sliding head 14 abuts against the second micro switch 10. Four countersunk holes are evenly arranged on the top of the planar moving body 4, and a telescopic spring is fixedly arranged between the bottom of each countersunk hole and the knob inner shell 5.

[0049] The pressing component is arranged at the bottom of the knob inner shell 5, and the knob inner shell 5 in the knob component is used as a pressing component. The knob inner shell 5 is cleverly used in the pressing and knob functions, making the structure more compact and reducing the space occupied by the knob. A telescopic spring is arranged between the planar moving body 4 and the knob inner shell 5 to achieve reset after pressing the knob inner shell 5.

[0050] A metal cover 18 is provided on the outside of the circumferential disk portion 42. The metal cover 18 is fixedly connected to the housing 1 by bolts. The metal cover 18 extends to the top of the circumferential disk portion 42 and contacts the upper surface of the circumferential disk portion 42, restricting the plane motion body 4 below the metal cover 18 to avoid upward movement due to the action of the telescopic springs, thereby making the structure compact and ensuring the realization of the knob pressing function and the plane motion function.

[0051] Each of the first micro switch 9 and the second micro switch 10 is electrically connected to the PCB board 2. The PCB board 2 converts the action signals of each micro switch into electrical signals for transmission, and can provide timely feedback and processing.

[0052] In summary, integrating a four-way movable planar motion component and a pressable pressing component into a knob allows one knob to perform multiple actions to correspond to the switch control of multiple functions, which is more operational and has a compact structure after integration, greatly reducing the space occupied by the interior panel.

[0053] Specifically, after the knob 11 is rotated, the knob bracket 3 is driven to rotate, and the sensor 21 detects the rotation of the knob bracket 3, transmits a signal to the PCB board and then feedbacks the action, presses the button cover on the knob 11, and the knob inner shell 5 moves in the plane moving body 4, and the bottom surface of the knob inner shell 5 presses the sliding head 14, and then the bottom of the sliding head 14 contacts the second micro switch 10, transmits the signal to the PCB board and then feedbacks the action, and then releases the pressure, and the knob inner shell 5 is reset under the action of each telescopic spring;

[0054] The knob 11 is pushed in one of the four directions to drive the knob inner shell 5 to move, thereby driving the planar motion body 4 to move. Then, the inclined surface of the trapezoidal platform 7 in this direction contacts the matching surface 81 of the corresponding push rod 8 and is continuously squeezed to provide a downward component of force for the push rod 8, so that the push rod 8 touches the first micro switch corresponding to the bottom, and then transmits the signal to the PCB board for feedback action. Then, the pressure is released, and the push rod 8 is reset under the action of the telescopic spring to push the planar motion body 4 and the knob inner shell 5 to reset.

[0055] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
