Where sensor 807 may be a hall sensor, flexible conductive members 803, 804 may comprise conductive rubber. When flexible electrical conductors 803, 804 are depressed, the corresponding electrical circuits on circuit board 801 are completed.
Further, light emitting elements 805 and 806 may be provided on the circuit board 801. The light emitting elements 805 and 806 can be connected to the light guiding ring 2 sleeved in the rotating ring 3 through a light guiding strip (not shown).

Fig. 8 is a schematic structural view of a display module of a variable hand-feeling rotary control switch structure according to an embodiment of the present invention.
As shown in fig. 8, in this embodiment, the display module 5 may include a display screen 501, a backlight module 502, a flat cable 503, a fixing post 504 and a fixing post 505. The display module 5 is fixedly mounted on the sliding module 7 through fixing posts 504 and 505, the display screen 501 is fixedly connected with the backlight module 502, and both the display screen 501 and the backlight module 502 can perform signal transmission with the circuit module 8 through the flat cable 503, so as to realize data connection with the circuit module 8.

The limited rotation can ensure that the flat cable passing through the upper display module 5 cannot be wound to death, and can also ensure that the rotating ring 3 connecting frame structure cannot collide and interfere with the fixing columns 504 and 505 in the rotating process.
Fig. 9 is a schematic view of an assembly structure of a damping generating element and a rotating ring of the variable hand feeling rotary control switch structure according to an embodiment of the present invention.
As shown in fig. 9, in the present embodiment, the damping generating element 12 may include a rotating shaft 1201 and a damping generating body (not shown in fig. 9). The rotating shaft 1201 of the damping generating element 12 may be fixedly connected to the rotating ring 3, and when the rotating ring 3 rotates, the rotating shaft 1201 may also rotate along with the rotating ring. The damping generating element 12 mainly functions to adjust the ease with which the rotating shaft 1201 can be rotated. The damping generating element 12 may be an electromagnetic damper, or a micro motor or a rotary self-locking device, which can realize the function of "preventing rotation" by adjusting PWM and forward and reverse rotation.
Furthermore, a vibration element 13 may be provided on the damping generating element 12. The vibration element 13 arranged on the damping generation element 12 can be in data connection with the signal processing module in the circuit module 8, so that control based on the signal processing module is realized and vibration is output.
The damping generating element 12 may be in data connection with a signal processing module in the circuit module 8, and the damping generating element 12 may receive the adjustment signal from the signal processing module. When the adjustment signal corresponding to the continued rotation of the rotary ring 3 does not coincide with the preset control target signal, the damping generation element 12 may output damping to the rotary ring 3 to prevent the continued rotation of the rotary ring 3. In case the damping generating element 12 has outputted damping to the rotary ring 3 to prevent a continued rotation of the rotary ring, the signal processing module may no longer control the damping generating element 12 to output damping to the rotary ring 3 if the rotary ring 3 is released first and then rotated again.
Fig. 10 is a schematic structural view of a connection ring of the variable hand feeling rotary control switch structure according to an embodiment of the present invention.
As shown in fig. 10, in the present embodiment, the connection ring 6 may include a connection assembly 601 therein, and the connection ring 6 may be fixedly connected to the circuit board 801 of the circuit module 8 through the connection assembly 601. Wherein the connection assembly 601 is inside the housing 10 and outside the sliding module 7.
It should be noted that, in order to ensure the subsequent normal use of the variable hand feeling rotary control switch structure, the diameter of the connection ring 6 may be slightly smaller than the caliber of the housing 10.
Fig. 11 is a schematic structural view of a housing of a variable hand feeling rotary control switch structure according to an embodiment of the present invention at a viewing angle.
FIG. 12 is a schematic structural view of a casing of a variable hand-feeling rotary control switch structure according to an embodiment of the present invention at another viewing angle
As shown in fig. 11 and 12, in the present embodiment, the housing 10 may include: a slider 1001, second spring fixing projections 1002 and 1003, and a harness connector through hole 1004. Among them, the slider 1001 may be disposed on the inner wall of the case 10, and the second spring fixing protrusions 1002 and 1003 may be disposed at the case inner bottom of the case 10.
One end of the spring 9 is sleeved on the first spring fixing protrusions 809 and 810 and is tightly supported by the first spring fixing protrusions 809 and 810 to the periphery, so that the spring is prevented from shaking or falling off. The other end of the spring 9 can be sleeved on the second spring fixing protrusions 1002 and 1003, so that the circuit module 8 is supported by the spring 9 relative to the bottom of the shell 10.
It should be noted that the spring 9 is relatively hard to compress, and during normal operation, the spring is not compressed and only functions to support and fix the circuit module 8. When the variable hand feeling rotary control switch structure is subjected to a large external impact force, the spring 9 is compressed, so that the whole part of the variable hand feeling rotary control switch structure exposed outside the installation decoration plate 11 is collapsed to be in a state of being flush with the outer surface of the installation decoration plate 11, and when the external force disappears, the spring 9 is recovered, and the collapsed part is recovered to the original position. The spring 9 arranged between the bottom of the shell 10 and the circuit module 8 can protect the part of the variable hand-feeling rotary control switch structure protruding out of the decorative plate 11 from being easily damaged, and on the other hand, when a driving accident occurs and a person in the vehicle collides with the variable hand-feeling rotary control switch structure, the part of the variable hand-feeling rotary control switch structure cannot be rigidly collided by the protruding part, so that the possible damage to the person in the vehicle is reduced as much as possible.

Fig. 14 is a schematic structural view of a sliding module of a variable hand feeling rotary control switch structure according to an embodiment of the present invention at another viewing angle.
Fig. 15 is a schematic structural view of a sliding module in another viewing angle according to an embodiment of the variable hand feeling rotary control switch structure of the present invention.
As shown in fig. 13, 14 and 15, in this embodiment, the sliding module 7 of the variable hand feeling rotary control switch structure according to the present invention may include: a chute 701 and a bottom platen 702. The sliding grooves 701 can be matched with the sliding blocks 1001 in the housing 10 to guide the up-and-down movement of the sliding module 7, so that the sliding module 7 sleeved inside the housing 10 can slide downwards along the axial direction of the housing 10, and the bottom pressing plate 702 in the sliding module 7 can flatten the flexible conductive members 803 and 804 in the circuit module.
It should be noted that, when the slide module is stationary, the bottom pressing plate 702 contacts the upper portions of the flexible conductive members 803 and 804, and the upper portion of the slide module 7 is limited by the upper portion of the housing 10 and cannot move upward, so that the slide module 7 is effectively prevented from escaping. When the sliding module 7 is moved downward by pressing with a finger, the flexible conductive members 803 and 804 are compressed, the circuit on the circuit board 801 is completed, the flexible conductive members 803 and 804 can be reset under the action of their own elasticity after the hand is released, and the sliding module 7 is also restored to the rest position.
Therefore, for the variable hand feeling rotary control switch structure, the aim of the invention can be achieved by the shell, the circuit module, the sliding module, the connecting ring, the rotating ring and the damping generating element, so that the switch number can be simplified, the product cost can be reduced, the automatic change of hand feeling reminding can be realized, the related information can be transmitted to the user, and better driving experience can be provided for the user. However, in order to achieve a better implementation effect of the present invention, it is preferable that the present invention further includes a cover, a light guide ring, a display module fixing ring, a display module, a spring, and a vibration element.
In an embodiment of the technical scheme, four functions of automobile driving mode selection, atmosphere lamp adjustment, air conditioner adjustment and multimedia selection can be switched logically through the variable hand feeling rotary control switch structure, and the four functions can correspond to four primary menus correspondingly.
Referring to fig. 1 to 15 in combination, when the hand-feeling-variable rotation control switch structure is used to control the corresponding functions of the vehicle, and the vehicle is started, the hand-feeling-variable rotation control switch structure of the present invention is started correspondingly, the light guide ring 2 is turned on, and the signal processing module in the circuit module 8 can control the display module 5 to display the driving mode selection page of the vehicle by default, and the driving mode selection page is seen by the user through the transparent window portion 101. At this time, if the user does not operate the variable hand feeling rotary control switch structure, any function will not be triggered.
When a user needs to switch the driving mode, the user only needs to press the sliding module 7, so that the sliding module 7 slides to the position of the squashed flexible conductive members 803 and 804, and the circuit on the circuit board is switched on, and a corresponding driving mode secondary menu is entered.
For example, when the driving mode needs to be switched from the economy mode to the sport mode, the transparent window portion 101 is pushed down by hand to drive the display module fixing ring 4, the display module 5, and the sliding module 7 to move downward together, so that the sliding module 7 can slide to the position where the flexible conductive members 803 and 804 are squashed, the circuit on the circuit board 801 is connected, the received signal is processed by the signal processing module (a chip and a circuit on the circuit board 801, not shown in the figure), and then the output signal is transmitted to the display module 5 through the flat cable 503, so that the secondary menu entering the driving function is displayed on the screen.
A user CAN select a driving mode which is required to be used by rotating the rotating ring 3, when the rotating ring 3 is rotated, a sensing element in the inner wall of the rotating ring 3 CAN move relative to a sensor 807 on the circuit board 801, the change CAN be transmitted into the signal processing module in a signal form, the signal processing module outputs a corresponding adjusting signal after processing, the adjusting signal is also transmitted to the display module 5 through the flat cable 503, corresponding driving mode information is displayed on a screen, when the user sees that the displayed driving mode is required, the user CAN press the transparent window part 101 again, the corresponding circuit on the circuit board 801 is switched on similarly, after the signal processing module processes the received signal, the adjusting signal is output through the wiring harness connector 808 and the corresponding wiring harness, the adjusting signal is transmitted to the vehicle gateway in a CAN/LIN mode, and then the adjusting signal is transferred to the driving mode controller by the gateway to switch the driving mode. The content displayed by the display module 5 is then automatically restored to the level one menu.
It should be noted that each time the sliding module 7 slides to the position where the flexible conductive members 803 and 804 are squashed, so that the circuit on the circuit board 801 is connected, and the signal processing module receives the signal, the signal is also sent out to control the light emitting elements 805 and 806 on the circuit board 801 to flicker, and the light is conducted to the light guide ring 2 through the light guide bar (not shown), so that the user sees that the light guide ring 2 flickers, thereby interacting with the user's operation.
In some embodiments, the user only needs to click normally when pressing down, and the circuit on the circuit board 801 has short connection time and does not need to press for a long time. When the user selects from the secondary menu, when the user turns to a certain function, the user is still for 1 second and does not operate, the system can automatically judge that the function is selected and started, the user does not need to press the function again by fingers, and the operation steps of the user are reduced. If the user wants to return to the previous level in a certain level of menu, the user only needs to press down the transparent window part 101 to make the circuit continuously connected for 1 second, and then the user can return to the previous level of menu (the signal transmission principle is the same as above).
It should be noted that when a user needs to adjust the entire atmosphere lamp, adjust the air conditioner, or select multimedia, the user only needs to rotate the rotating ring 3, display the interface and the operation logic in the display module 5, press down and enter the second-level menu to select adjustment, and the operation principle is the same as above and is not described again. Therefore, the variable hand feeling rotary control switch structure provided by the invention effectively integrates air conditioner regulation, atmosphere lamp regulation and multimedia selection on the basis of the driving mode selection switch, greatly reduces the product cost and reduces the number of switches.
In addition, another core function of the variable hand feeling rotary control switch structure and the control method of the invention is a variable hand feeling feedback structure taking the damping generating element 12 as a core, and the principle and the control method thereof are as follows:
(1) In the operations of adjusting atmosphere lamps, using air conditioners, listening songs by multimedia and the like, the use habit of a user can be recorded by the variable hand feeling rotary control switch structure in a certain time period.
For example: when a user turns on the air conditioner in the vehicle again and rotates the rotating ring 3 to adjust the temperature to 24 degrees, the system continues to rotate, and an adjusting signal corresponding to the continuous rotation of the rotating ring 3 does not accord with the control target signal, the signal processing module in the circuit module 8 can control the damping generation element 12 to output damping to the rotating ring so as to prevent the rotating ring 3 from continuing to rotate. Meanwhile, the signal processing module can also send a signal to control the vibration device 13 to work, so that the vibration device can vibrate quickly to remind a user that the temperature is the favorite temperature, and the user can release hands and cannot adjust the temperature. The user only needs to loosen the hand first and then rotates the rotating ring 3 again, and the signal processing module judges that the user needs to continue selecting the temperature by himself and does not provide damping and vibration feedback any more.
That is, in the case where the damping generating element 12 has output damping to the rotary ring 3 to prevent the rotary ring 3 from continuing to rotate, the rotary ring 3 may be released first, and then the rotary ring 3 may be rotated again, and the signal processing module may no longer control the damping generating element to output damping to the rotary ring.
(2) When the variable hand feeling rotary control switch structure leaves a factory, the parameter settings such as the optimal air conditioner temperature, the optimal volume without damaging ears and the like can be customized in the interior according to ergonomics and other related knowledge.
When the structure leaves the factory, the structure of the variable hand feeling rotation control switch of the present invention may input a preset control target signal, and when an adjustment signal corresponding to the continuous rotation of the rotating ring 3 in the structure of the variable hand feeling rotation control switch of the present invention does not match the preset control target signal, the signal processing module may also control the damping generating element 12 to output a damping to the rotating ring 3 to prevent the rotating ring 3 from continuously rotating.
In conclusion, the variable hand feeling rotary control switch structure and the control method integrate air conditioner adjustment, atmosphere lamp adjustment and multimedia selection on the basis of the rotary driving mode selection switch, greatly reduce the product cost, reduce the number of switches, enable the instrument panel to be simpler, provide more play space for interior design and improve the technological sense of the switch operation of the electric appliance. Meanwhile, the operation hand feeling of the control method of the variable hand feeling rotary control switch structure can be changed in a set scene, for example, when a user rotates a menu to pass through the most common function, the hand feeling can be automatically changed to remind the user, so that relevant information is transmitted to the user, better driving experience is provided for the user, the market competitiveness is greatly improved, and the development trend of intelligent automobiles is met.
It should be noted that the combination of the features in the present application is not limited to the combination described in the claims of the present application or the combination described in the specific examples, and all the features described in the present application may be freely combined or combined in any manner unless contradicted by each other.
