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.

[0032] 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.

[0033] like Figure 1-7 As shown, a double-layer knob structure includes a bracket 1 and a PCB board 2, on which a first sensor 3 and a second sensor 4 are installed and electrically connected, the bracket 1 includes a central bracket 11, an annular bracket 12 and an outer bracket 13, and two concentric spaces both in annular structures are formed between the central bracket 11 and the annular bracket 12 and between the annular bracket 12 and the outer bracket 13, and a first knob assembly and a second knob assembly are respectively arranged in the two annular spaces, and the two knob assemblies are placed in the same place and are independently controlled without interfering with each other, thereby effectively saving the space required for the two knobs.

[0034] The first knob assembly includes a first knob frame 6 with an annular structure and a first bearing 5 installed on the first knob frame 6. The second knob assembly includes a second knob frame 9 with an annular structure and a second bearing 8 installed on the second knob frame 9. The first knob frame 6 is fixedly connected to the top with a first knob 7, and the second knob frame 9 is buckled with the top with a second knob 10. The outer surfaces of the first knob 7 and the second knob 10 may have anti-slip patterns to save effort when turning the knob and prevent the knob from sliding and affecting people's judgment of the knob rotation angle.

[0035] The first knob frame 6 includes a first detection end foot 61 located at the bottom and a first adjusting portion 62 located above the first detection end foot 61, and the second knob frame 9 includes a second detection end foot 91 located at the bottom and a second adjusting portion 92 located above the second detection end foot 91. The first detection end foot 61 and the second detection end foot 91 both have an annular grid structure, and the outer surfaces of the first adjusting portion 62 and the second adjusting portion 92 both have a wavy structure.

[0036] The annular first knob frame 6 and the second knob frame 9 are equipped with bearings of respective sizes on the outer surfaces for controlling the rotation, thereby ensuring the rotation of the knobs, avoiding the knobs from getting stuck, and increasing the smoothness of the knob rotation.

[0037] Three gear seats 14 are fixedly set on the base of the bracket 1, and each gear seat 14 is located on the outside of the second knob frame 9. Each gear seat 14 is provided with a spring cavity hole 15 on the side facing the central bracket 11, and each spring cavity hole 15 is provided with a telescopic spring, one end of the telescopic spring is fixedly connected to the bottom end of the spring cavity hole 15, and a gear head 16 is fixed to the other end of the telescopic spring, and the two gear heads 16 are respectively in contact with the outer surface of the first adjusting portion 62, and the other gear head 16 is in contact with the outer surface of the second adjusting portion 92.

[0038] By utilizing the shift head 16 to support the first shift adjusting portion 62 and the second shift adjusting portion 92 having a wavy structure, the contact portion of the shift head 16 has a hemispherical structure. When the two knobs are rotated, the first shift adjusting portion 62 and the second shift adjusting portion 92 having a wavy structure push the two shift heads 16 to reciprocate, and during the process, resistance opposite to the rotation direction is periodically provided, thereby increasing the feel when turning the knob and preventing the knob from rotating at will after being turned, making the control of turning the knob more precise.

[0039] The detection ends of the first sensor 3 and the second sensor 4 pass through the bracket 1 and are placed at the bottom of the bracket 1. Both the first sensor 3 and the second sensor can be photoelectric sensors. The detection ends of the first sensor 3 and the second sensor 4 include two detection surfaces and are in a "U"-shaped structure as a whole. The two detection surfaces of the detection end of the first sensor 3 are respectively located on the inner and outer sides of the foot 61 of the first detection end, and the two detection surfaces of the detection end of the second sensor 4 are respectively located on the inner and outer sides of the foot 91 of the second detection end.

[0040] Sensors are arranged on the inner and outer sides of the first detection end foot 61 and the second detection end foot 91. At the same time, the first detection end foot 61 and the second detection end foot 91 are grid structures. Photoelectric sensors are used to sense and detect the grid structure, and the rotation amplitude of the knob is accurately judged by receiving and judging the optical signal, so that the knob rotation can be responded to in time and corresponding actions can be taken.

[0041] The annular bracket 12 and the outer bracket 13 are in a stepped structure, and serve as mounting seats for the first bearing 5 and the second bearing 8 respectively. The first bearing 5 is clamped on the annular bracket 12, and the middle part of the first knob bracket 6 is in a stepped structure, and its stepped surface contacts the upper end surface of the first bearing 5, so that the entire first knob assembly is fixed to the bracket 1 through the first bearing 5; the second bearing 8 is clamped on the outer bracket 12, so that the entire second knob assembly is fixed to the bracket 1 through the second bearing 8, and the bracket 1 is used as two bearing seats of different sizes to fix the first bearing 5 and the second bearing 8, so as to reasonably utilize the space of the bracket 1 and further reduce the space required for the knob.

[0042] A decorative piece 17 is provided between the first knob 7 and the second knob 10 to prevent dust and other objects from falling into the gap between the two knob components and causing jamming or damage to the knobs, thereby ensuring the rotation accuracy and service life of the knobs. The decorative piece 17 is relatively stationary with respect to the bracket 1 and does not participate in the rotation. The positions of the two knobs can be distinguished according to the position of the decorative piece 17, so that the knob to be rotated can be found more accurately.

[0043] The annular bracket 12 and the second knob bracket 9 are provided with a support member 18, and the support member 18 is buckled with the annular bracket 12. At the same time, a heightening member 19 is fixedly connected above the central bracket 11. The support member 18 is buckled in the annular bracket 12 to provide support for the first bearing 5, thereby enhancing the stability of the first bearing 5, and the heightening member 19 can provide support for the first knob 7, thereby enhancing the internal compactness of the first knob assembly and the entire knob, thereby enhancing the overall bending strength.

[0044] Specifically, the first knob assembly and the second knob assembly are respectively located on both sides of the decorative member 17. When the first knob 7 is rotated, the first knob frame 6 is driven to rotate. The rotation angle is more stably controlled based on the resistance feedback brought by the gear head 16. The first detection end foot 61 with a grid structure continuously passes through the first sensor 3. Then the sensor converts the received light signal into an electrical signal and transmits it to the PCB board, and judges the rotation angle of the knob based on the frequency and number of the electrical signal. Then the signal is transmitted to control the vehicle to perform corresponding actions. Similarly, when the second knob 10 is rotated, the second knob frame 9 is driven to rotate. The rotation angle is more stably controlled based on the resistance feedback brought by the other gear head 16. The second detection end foot 91 with a grid structure continuously passes through the second sensor 4. Then the sensor converts the received light signal into an electrical signal and transmits it to the PCB board, and judges the rotation angle of the knob based on the frequency and number of the electrical signal. Then the signal is transmitted to control the vehicle to perform corresponding actions.
