Figure 3 is a cross-sectional view of a hidden knob screen according to an exemplary embodiment.

[0058] like Figures 1 to 3 As shown, the present disclosure provides a hidden knob screen 100 , including: a knob screen assembly 10 , a PCB board assembly 20 , an electromagnet assembly 30 and a mounting component 40 .

[0059] Among them, a groove is set inside the installation component 40, and the PCB board assembly 20 and the electromagnet assembly 30 are both arranged in the groove inside the installation component 40. The installation component 40 is used to fix and hide the knob screen assembly 10.

[0060] The PCB board assembly 20 includes a PCB circuit board 21, an elastic component 23 and a first permanent magnet 22. The PCB circuit board 21 is electrically connected to the knob screen assembly 10. The first permanent magnet 22 is fixed on the PCB circuit board 21.

[0065] The electromagnet assembly 30 is arranged at the bottom of the groove inside the mounting component 40, and the knob screen assembly 10 is hidden in the groove inside the mounting component 40 or reset through the magnetic force between the first permanent magnet 22 of the PCB board assembly 20 and the electromagnet assembly 30 and the elastic force of the elastic component 23.

[0066] Among them, when the first permanent magnet 22 of the PCB board assembly 20 and the electromagnet assembly 30 attract each other, the knob screen assembly 10 overcomes the elastic force of the elastic component 23 and hides from the initial position to the internal groove of the mounting component 40; when the first permanent magnet 22 of the PCB board assembly 20 and the electromagnet assembly repel each other, the knob screen assembly 10 is reset to the initial position from the internal groove of the mounting component 40 by the elastic action of the elastic component 23.

[0067] Through the above technical solution, the knob screen assembly 10 is electrically connected to the PCB circuit board 21, and the magnetic force between the first permanent magnet 22 fixed on the PCB circuit board 21 and the electromagnet assembly 30 arranged in the groove inside the mounting component 40 and the elastic force of the elastic component 23 are used to achieve the hiding or resetting of the knob screen assembly 10. When the knob screen assembly 10 is not needed, the knob screen assembly 10 is hidden in the groove inside the mounting component 40 to maintain its appearance and prevent collision damage to the knob screen assembly 10.

[0068] In a possible embodiment, the electromagnet assembly 30 includes a coil and a magnetic core. The magnetic core is arranged inside the coil. The coil is used to change the direction of the magnetic field, and the magnetic core is used to conduct the magnetic field.

[0069] The magnetic core itself does not have magnetism and is only used to conduct the magnetic field.

[0070] The coil is electrically connected to the PCB circuit board 21 of the PCB board assembly 20, and the current direction switching circuit and current intensity adjustment circuit on the PCB circuit board 21 are used to change the current direction and current intensity connected in the coil to change the magnetic field direction and magnetic force of the electromagnet assembly 30.

[0071] In a possible embodiment, a hidden knob screen 100 may further include a bracket assembly 50, the bracket assembly 50 includes a first bracket 51, a second bracket 52, and a third bracket 53, the first bracket 51 is connected to the second bracket 52, the second bracket 52 is slidably connected to the third bracket 53, the first bracket 51 is used to support the knob screen assembly 10, and the second bracket 52 and the third bracket 53 act on the pressing operation of the knob screen assembly 10.

[0072] A through hole is provided at the center of the first bracket 51 , and the through hole is used to pass the power supply cable of the knob screen assembly 10 .

[0073] The inner wall of the second bracket 52 is connected to the outer wall of the third bracket 53 by sliding fit, and a gap is set between the inner wall of the second bracket 52 and the outer wall of the third bracket 53 to act on the pressing function of the rotating screen assembly.

[0074] The second bracket 52 is also fixedly connected to the PCB board assembly 20 .

[0075] As an example, when the user presses the rotating screen assembly, relative sliding occurs between the second bracket 52 and the third bracket 53 .

[0076] A plurality of flanges are evenly arranged on the outer surface of one end of the third bracket 53 , and the flanges are used to prevent rotational movement between the second bracket 52 and the third bracket 53 .

[0077] In a possible embodiment, a hidden knob screen 100 may also include a bottom cover component 60, which is arranged at the bottom of the groove inside the mounting component 40, the bottom cover component 60 is fixedly connected to the third bracket 53, the electromagnet assembly 30 is fixedly connected to the bottom cover component 60, and the other end of the elastic component 23 is fixedly connected to the bottom cover component 60.

[0078] The mounting component 40 of the present disclosure is also fixedly connected to the third bracket 53 , and the PCB board assembly 20 and the electromagnet assembly 30 are arranged between the third bracket 53 and the mounting component 40 .

[0079] In a possible embodiment, the knob screen assembly 10 includes a touch display screen 13, a decorative ring 11, and a rotating seat 12. The decorative ring 11 is fixedly connected to the outer ring of the rotating seat 12. The touch display screen 13 is arranged on the first bracket 51, and the rotating seat 12 acts on the rotation operation of the knob screen assembly 10.

[0080] The touch display screen 13 of the present disclosure is electrically connected to the PCB circuit board 21 of the PCB board assembly 20 , and is fixedly connected to the first bracket 51 .

[0081] The decorative ring 11 is used to protect the touch display screen 13. The touch display screen 13 is used to implement touch control, and a user can touch the touch display screen 13 to display screen information on the touch display screen 13.

[0082] The rotating seat 12 is coaxially connected to the first bracket 51 , and a gap is provided between the rotating seat 12 and the first bracket 51 to act on the rotation function of the knob screen assembly 10 .

[0083] In a possible embodiment, a hidden knob screen 100 may further include an encoder component 70 , and the encoder component 70 is electrically connected to the PCB circuit board 21 .

[0084] The encoder assembly 70 includes an encoder holder, an encoder inner ring 71 and an encoder outer ring 72. The encoder holder is used to axially fix the encoder inner ring 71 and the encoder outer ring 72. The encoder outer ring 72 is fixedly connected to the inner ring of the rotating seat 12. The inner ring of the encoder is fixedly connected to the first bracket 51. The encoder inner ring 71 and the encoder outer ring 72 act on the rotation operation of the knob screen assembly 10.

[0085] The encoder holder is used to prevent the encoder inner ring 71 and the encoder outer ring 72 from axially moving.

[0086] The encoder inner ring 71 and the encoder outer ring 72 are coaxially matched, and a gap is set between the matching. A lubricating material is filled in the gap between the encoder inner ring 71 and the encoder outer ring 72 to act on the rotation function of the knob screen assembly 10 and reduce the damping of the relative rotation between the encoder inner ring 71 and the encoder outer ring 72.

[0087] As an example, when the user rotates the knob screen assembly 10, the rotating seat 12 of the knob screen assembly 10 rotates, and the encoder outer ring 72 and the encoder inner ring 71 rotate relative to each other, generating an angular displacement. The encoder assembly 70 converts the generated angular displacement into an electrical signal and transmits it to the PCB circuit board 21.

[0088] Figure 4 The figure is a flow chart of a method for controlling a hidden knob screen according to an exemplary embodiment.

[0089] like Figure 4 As shown, the present disclosure also provides a control method for a hidden knob screen, including S11 to S12, so as to hide the knob screen component.

[0090] S11, setting the magnetic core of the electromagnet assembly as a second permanent magnet.

[0091] The magnetic pole direction of the second permanent magnet is opposite to that of the first permanent magnet, and the knob screen assembly is located at the initial position.

[0092] S12, connecting the coil of the electromagnet assembly with a current in a first direction to demagnetize and re-magnetize the second permanent magnet, the first permanent magnet and the second permanent magnet attract each other, and the knob screen assembly overcomes the elastic force of the elastic component and hides from the initial position into the internal groove of the mounting component.

[0093] As an example, in a normal non-powered state, the second permanent magnet has opposite magnetic pole directions to the first permanent magnet, the second permanent magnet and the first permanent magnet repel each other, and the elastic component serves as initial damping. Based on the elastic effect and connection effect of the elastic component, the knob screen assembly is located in the initial position, and the knob screen assembly is not hidden in the mounting component.

[0094] When the knob screen assembly needs to be hidden, the coil of the electromagnet assembly is connected to a current in a first direction, and the coil generates a magnetic field opposite to that of the second permanent magnet. The magnetic field generated by the coil inside the second permanent magnet interacts with the magnetic field generated by the second permanent magnet. Since the magnetic field generated by the coil is greater than the magnetic field generated by the second permanent magnet, the second permanent magnet is demagnetized.

[0095] After the second permanent magnet is demagnetized, the first permanent magnet has strong magnetism, the first permanent magnet and the second permanent magnet attract each other, the coil continues to connect the current in the first direction, the second permanent magnet is remagnetized, and the first permanent magnet and the second permanent magnet achieve permanent attraction.

[0096] The knob screen assembly is based on the mutual attraction between the first permanent magnet and the second permanent magnet, overcoming the elastic force of the elastic component to hide from the initial position into the groove inside the mounting component, thereby maintaining the aesthetics and safety of the knob screen assembly and preventing users from colliding with the rotating screen assembly.

[0097] like Figure 4 As shown, in a possible embodiment, a method for controlling a hidden knob screen may further include S13 to automatically reset the knob screen assembly.

[0098] S13, when the knob screen assembly is hidden in the groove inside the mounting component, the coil of the electromagnet assembly is connected to a current in a second direction to demagnetize and remagnetize the second permanent magnet, the first permanent magnet and the second permanent magnet repel each other, and the knob screen assembly is reset to the initial position by the elastic force of the elastic component.

[0099] The current in the first direction is opposite to the current in the second direction.

[0100] As another example, when the knob screen assembly is hidden in the groove inside the mounting component, the coil of the electromagnet assembly is connected to a current in the second direction. The coil is connected to the current in the second direction, and the coil generates a magnetic field opposite to that of the second permanent magnet. The magnetic field generated by the coil inside the second permanent magnet interacts with the magnetic field generated by the second permanent magnet. Since the magnetic field generated by the coil is greater than the magnetic field generated by the second permanent magnet, the second permanent magnet is demagnetized.

[0101] After the second permanent magnet is demagnetized, the first permanent magnet has strong magnetism, the first permanent magnet and the second permanent magnet are still attracted to each other, the coil continues to connect the current in the second direction, the second permanent magnet is remagnetized, and the magnetic pole direction of the remagnetized second permanent magnet is opposite to that of the first permanent magnet, so the first permanent magnet and the second permanent magnet repel each other.

[0102] The knob screen assembly is based on the mutual repulsion between the first permanent magnet and the second permanent magnet, and is reset to the initial position by the elastic force of the elastic component, thereby realizing automatic reset of the knob screen assembly.

[0103] Figure 5 The figure is a flow chart of a method for controlling a hidden knob screen according to an exemplary embodiment.

[0104] like Figure 5 As shown, the present disclosure also provides a control method for a hidden knob screen, including S21 to S22, so as to use the knob screen assembly as an emergency button.

[0105] S21, setting the magnetic core of the electromagnet assembly to a third permanent magnet, and setting the touch display screen to an ink screen.

[0106] The third permanent magnet has the same magnetic pole as the first permanent magnet, the distance between the third permanent magnet and the first permanent magnet is greater than a preset distance threshold, and the knob screen assembly is located at an initial position.

[0107] The ink screen has the function of power-off retention, and the screen information can still be displayed after power off.

[0108] S22, in the preset scenario state, press the knob screen assembly and keep it in place, the third permanent magnet and the first permanent magnet attract each other, the knob screen assembly overcomes the elastic force of the elastic component and hides from the initial position to the internal groove of the mounting component, the hidden knob screen is electrically disconnected from the external circuit, and the ink screen displays the screen information.

[0109] Among them, the preset scenario state is the state of sudden emergency event.

[0110] As an example, the knob screen assembly is used as an emergency button. In a normal state, the coil of the electromagnet assembly is not energized, the third permanent magnet has the same magnetic pole as the first permanent magnet, and since the axial distance between the third permanent magnet and the first permanent magnet is large and greater than a preset distance threshold, there is no tendency of mutual attraction between the third permanent magnet and the first permanent magnet, and the knob screen assembly is bounced up by the elastic component, and the knob screen assembly is located at the initial position.

[0111] In the event of an emergency, the user presses the knob screen assembly and keeps it in place, the elastic component is compressed, and the axial distance between the third permanent magnet and the first permanent magnet decreases. When the axial distance is less than a preset distance threshold and the magnetic poles of the third permanent magnet and the first permanent magnet are in the same direction, the third permanent magnet and the first permanent magnet attract each other, and the third permanent magnet and the first permanent magnet overcome the elastic force of the elastic component to achieve permanent attraction.

[0112] When the knob screen assembly is pressed, the electrical connection between the hidden knob screen and the external circuit is disconnected, and the ink screen continues to display the screen information due to the power outage.

[0113] By using the hidden knob screen as an emergency button, emergency braking can be implemented to ensure safety in the event of an emergency.

[0114] like Figure 5 As shown, in a possible embodiment, the control method of a hidden knob screen disclosed in the present invention may further include S23, resetting the knob screen component serving as an emergency button.

[0115] S23, when the knob screen assembly is hidden in the groove inside the mounting component and the hidden knob screen assembly is electrically disconnected from the external circuit, a current in the second direction is connected to the coil of the electromagnet assembly to demagnetize and remagnetize the third permanent magnet, the first permanent magnet and the third permanent magnet repel each other, and the knob screen assembly is reset to its initial position by the elastic force of the elastic component.

[0116] As another example, when the knob screen assembly is pressed and held in place as an emergency button, if the knob screen assembly needs to be reset, the coil of the electromagnet assembly is connected to a current in a second direction, the coil generates a magnetic field opposite to that of the third permanent magnet, and the magnetic field generated by the coil inside the third permanent magnet interacts with the magnetic field generated by the third permanent magnet. Since the magnetic field generated by the coil is greater than the magnetic field generated by the third permanent magnet, the third permanent magnet is demagnetized.

[0117] After the third permanent magnet is demagnetized, the first permanent magnet has strong magnetism, the first permanent magnet and the third permanent magnet are still attracted to each other, the coil continues to connect the current in the second direction, the third permanent magnet is remagnetized, and the magnetic pole of the remagnetized third permanent magnet is opposite to that of the first permanent magnet, so the first permanent magnet and the third permanent magnet repel each other.

[0118] The knob screen assembly is based on the mutual repulsion between the first permanent magnet and the third permanent magnet, and is reset to the initial position by the elastic force of the elastic component, thereby realizing automatic reset of the knob screen assembly.

[0119] The present disclosure also provides a method for controlling a hidden knob screen, which may also include:

[0120] When the coil is connected to a current in the second direction, the force required for the user to press the knob screen assembly is adjusted by adjusting the current intensity in the second direction.

[0121] By adjusting the intensity of the current in the second direction connected to the coil, the repulsive force between the first permanent magnet and the electromagnet assembly can be adjusted, thereby adjusting the force required by the user to press the knob screen assembly, thereby adjusting the feel of the pressing function of the hidden knob screen and improving the user's user experience.

[0122] The above describes the specific embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which does not affect the essence of the present disclosure.
