[0056] a position sensing component, the position sensing component being used to determine the type of the execution character;

[0057] A control body, the control body is used to execute the control instruction of the execution character;

[0058] A circuit board is connected to the position sensing component and the control body respectively.

[0059] Example 1:

[0060] Attachment Figure 1 This is a structural diagram of an embodiment of the control device of this application. Figure 1 As shown, the present application provides a control device, which is installed in a position inside the car where human-computer interaction is possible. Further, the position can be the center console area, the steering wheel switch area, the door interior panel area, the roof, etc.

[0061] Please refer to the attached Figure 1 As shown, the control device of the present application further includes a cover plate 100 , and a light-transmitting hole 110 is provided on the cover plate 100 , and the light-transmitting hole 110 is provided through the cover plate 100 .

[0062] In one embodiment, the cross-section of the cover plate 100 is circular or rectangular.

[0063] Please refer to the attached Figure 1 As shown, the control device of the present application also includes a character plate 200. The character plate 200 is disposed at the bottom of the cover plate 100, and the light-transmitting hole 110 is disposed corresponding to the character plate 200. A plurality of characters are disposed on the surface of the character plate 200. This surface of the character plate 200 is disposed corresponding to the cover plate 100, i.e., the surface of the character plate 200 adjacent to the cover plate 100. In the present application, the cross-section of the character plate 200 is a circular structure, and the surface of the character plate 200 on which the characters are disposed is the end surface of the character plate 200 adjacent to the cover plate 100. The characters are spaced apart on the surface of the character plate 200. Furthermore, the characters are spaced apart circumferentially or longitudinally on the surface of the character plate 200. The direction in which the characters are disposed on the character plate 200 depends on the movement between the cover plate 100 and the character plate 200.

[0064] The character plate 200 is movably connected to the cover plate 100. When the character plate 200 is movably connected to the cover plate 100, the light-transmitting holes 110 form a movement track on the character plate 200, and the characters 210 are arranged on the character plate 200 along the movement track. When the character plate 200 is movably connected to the cover plate 100, the light-transmitting holes 110 display different characters, each corresponding to a different control command. The characters displayed in the light-transmitting holes 110 are execution characters, which are the characters currently executing the control command. The execution characters can also represent the type of control command currently being executed, so that the operator can know the type of the current control command.

[0065] In one embodiment, the movement track formed by the light-transmitting hole 110 on the character plate 200 is circular, linear, or curved. Furthermore, the movement track formed by the light-transmitting hole 110 on the character plate 200 depends on the movement mode between the character plate 200 and the cover plate 100.

[0066] In this application, the cover plate 100 and the character plate 200 are connected in a rotational or translational manner. When the character plate 200 and the cover plate 100 are rotationally connected, the light-transmitting hole 110 forms a circular trajectory on the character plate 200. Furthermore, between the cover plate 100 and the character plate 200, the cover plate 100 is either a fixed component or a rotating component, while the character plate 200 is either a fixed component or a rotating component. In one embodiment, the cover plate 100 is the fixed component, and the character plate 200 is the rotating component.

[0067] When the character board 200 is rotatably connected to the cover plate 100, the area of the cover plate 100 is not smaller than the area of the character board 200, so as to ensure that the cover plate 100 covers other areas of the character board 200 except the area displayed by the light-transmitting hole 110, and further realize that during the rotation process, the character board 200 only displays one character 210 at most, so as to improve the accuracy of the control device in executing the control instructions and avoid the operator from being confused about the instruction currently being executed.

[0068] In one embodiment, the rotation axis of the character plate 200 is perpendicular to the cover plate 100. Furthermore, the character plate 200 and the cover plate 100 are coaxially disposed.

[0069] When the character plate 200 is translatively connected to the cover plate 100, the light-transmitting aperture 110 forms a linear or curved trajectory on the character plate 200. Furthermore, between the cover plate 100 and the character plate 200, the cover plate 100 serves as the translating member, while the character plate 200 serves as the fixed member. When the character plate 200 and the cover plate 100 are translatively connected, the area of the cover plate 100 is smaller than that of the character plate 200, facilitating the movement of the cover plate 100 on the character plate 200.

[0070] In one embodiment, the area of the light-transmitting hole 110 is larger than the area of a single character.

[0071] Please refer to the attached Figure 1 As shown, the control device of the present application further includes a housing assembly 600, which includes a rotating sleeve 610. The rotating sleeve 610 is mounted on the outside of the character plate 200 and is fixedly connected to the character plate 200 to achieve synchronous rotation of the rotating sleeve 610 and the character plate 200. In one embodiment, the character plate 200 is disposed on the end surface of the rotating sleeve 610.

[0072] The housing assembly 600 of the present application further includes a transmission sleeve 620 , which is located at the bottom of the rotating sleeve 610 , and the rotating sleeve 610 is sleeved outside the transmission sleeve 620 , and the transmission sleeve 620 and the rotating sleeve 610 rotate synchronously.

[0073] The housing assembly 600 of the present application further includes a fixing sleeve 630, which is rotatably connected to the transmission sleeve 620 and fixedly connected to the object to be loaded. In the present application, the object to be loaded refers to the center console area, the steering wheel switch area, the door interior panel area, the roof, etc.

[0074] The housing assembly 600 of the present application further includes a transmission assembly 640 , which is rotatably connected to the transmission sleeve 620 . The position sensing assembly 300 is used to monitor the rotation angle of the transmission assembly 640 to further determine the type of executed character.

[0075] In one embodiment, the transmission assembly 640 is a transmission gear, and transmission teeth are circumferentially provided on the bottom of the transmission sleeve 620 , and the transmission gear is meshed with the transmission teeth.

[0076] Please refer to the attached Figure 1 As shown, the control device of the present application also includes a position sensing component, which is used to determine the type of execution character. The position sensing component of the present application includes an induction magnet and a Hall sensor. The induction magnet is arranged on the transmission component 640, and the transmission component 640, the rotating sleeve 610 and the character board 200 rotate synchronously. The Hall sensor is arranged on one side of the induction magnet, and the Hall sensor is used to record the initial position of the induction magnet, the coordinate orientation of each character relative to the initial position, and the coordinate orientation of the light-transmitting hole 110 relative to the initial position. When the coordinate orientation of the light-transmitting hole 110 is fixed, the position sensing component can calculate the corresponding character in the light-transmitting hole 110 under the rotation of the character board 200. The position sensing component is connected to the circuit board, and the position sensing component is used to send the execution character information in the light-transmitting hole 110 to the circuit board.

[0077] In one embodiment, the position sensing component can determine that the executed character is the character that the operator subjectively desires to execute only after the character board 200 has been stationary for a fixed period of time.

[0078] Please refer to the attached Figure 1As shown, the control device of the present application also includes a control body 400, which is used to execute the control instructions for the execution character. The control body 400 is connected to the circuit board. After the position sensing component sends the execution character information to the circuit board, the circuit board finds the control instruction corresponding to the execution character information and associates the control instruction with the control body 400. The operator controls the control body 400 through manipulation means to enable the control body 400 to execute the control instruction corresponding to the execution character 210.

[0079] In this application, the manipulation means include touch, gesture, voice, etc. In one embodiment, the manipulation body 400 is a touch film, which is located in the light-transmitting hole 110 and is made of a transparent material, thereby facilitating the display of characters in the light-transmitting hole 110 .

[0080] Please refer to the attached Figure 1 As shown, the control device of the present application further includes a lighting assembly, which corresponds to the light-transmitting hole 110, and the character plate 200 is disposed between the lighting assembly and the cover 100. The lighting assembly emits illumination light, which passes through the character plate 200 to illuminate the execution character and display it in the light-transmitting hole 110.

[0081] Attachment Figure 2 This is a structural diagram of the character board of this application. Figure 2 As shown, a plurality of characters 210 are arranged circumferentially at intervals on the character plate 200 of the present application.

[0082] In the present application, four characters 210 are provided on the character board 200, namely, hazard warning, parking, air conditioning cooling, and air conditioning heating.

[0083] Example 2:

[0084] Attachment Figure 3 This is a front view of another embodiment of the control device of this application. Figure 4 This is a left side view of another embodiment of the control device of this application. Figure 3 and attached Figure 4 As shown, the present application provides a control device, which is installed in a position inside the car where human-computer interaction is possible. Further, the position can be the center console area, the steering wheel switch area, the door interior panel area, the roof, etc.

[0085] Please refer to the attached Figure 3 or attached Figure 4 As shown, the control device of the present application further includes a cover plate 100 , and a light-transmitting hole 110 is provided on the cover plate 100 , and the light-transmitting hole 110 is provided through the cover plate 100 .

[0086] In one embodiment, the cross-section of the cover plate 100 is circular or rectangular.

[0087] Please refer to the attached Figure 3 or attached Figure 4 As shown, the control device of the present application also includes a character plate 200, which is disposed at the bottom of the cover plate 100, with the light-transmitting hole 110 corresponding to the character plate 200. A plurality of characters are arranged on the surface of the character plate 200. This surface of the character plate 200 is disposed corresponding to the cover plate 100, i.e., the surface of the character plate 200 on the side closest to the cover plate 100. In the present application, this surface is composed of a plurality of side surfaces of the character plate 200. In the present application, the character plate 200 is a regular polygonal structure, and the number of side surfaces 220 of the character plate 200 is a positive even number greater than two, i.e., the number of side surfaces 220 of the character plate 200 is 4, 6, 8, etc. In one embodiment, the number of side surfaces 220 of the character plate 200 is 6. The surface of the character plate 200 on which characters are arranged is the side surface 220 of the character plate 200.

[0088] In this application, the character plate 200 is rotatably connected to the cover plate 100. When the character plate 200 and the cover plate 100 are rotatably connected, the light-transmitting holes 110 form a motion trajectory on the character plate 200, and the characters are arranged on the character plate 200 along the motion trajectory. The motion trajectory formed by the light-transmitting holes 110 on the character plate 200 is a polygonal structure formed around the side surface 220 of the character plate 200. Furthermore, between the cover plate 100 and the character plate 200, the cover plate 100 is either a fixed component or a rotating component, and the character plate 200 is the other of the two. In one embodiment, the cover plate 100 is the fixed component and the character plate 200 is the rotating component.

The side surface groups include two parallel side surfaces 220, one of the side surfaces 220 in the side surface group is provided with characters, and the other side surface 220 in the side surface group is transparent.

[0090] When the character board 200 and the cover plate 100 are movably connected, the light-transmitting hole 110 displays different characters, and each character corresponds to a different control instruction. The character displayed in the light-transmitting hole 110 is an execution character, and the execution character is the character of the currently executed control instruction, and the execution character can represent the type of the currently executed control instruction, so that the operator can know the type of the current control instruction.

[0091] In one embodiment, the rotation axis of the character plate 200 is parallel to the cover plate 100 , and the rotation axes of the cover plate 100 and the character plate 200 are both arranged along the first direction X. In this application, the first direction X is the front-to-back direction of the control device.

[0092] Please refer to the attached Figure 3 or attached Figure 4As shown, the control device of the present application further includes a driving component 700 , and the driving component 700 is used to drive the character board 200 to rotate.

[0093] In one embodiment, the drive assembly 700 is a manual drive device or an electric drive device.

The driven wheel 720 is fixedly connected to the character board 200, and the driving wheel 710 and the driven wheel 720 are rotationally connected. In a specific embodiment, the operator rotates the driving wheel 710 to drive the driven wheel 720 and the character board 200 to rotate simultaneously, thereby switching the characters within the light-transmitting hole 110.

[0094] Please refer to the attached Figure 3 or attached Figure 4 As shown, the control device of the present application also includes a position sensing component 300, which is used to determine the type of executed character. The position sensing component 300 of the present application includes a sensing magnet 310 and a Hall sensor 320. The sensing magnet 310 is mounted on the character plate 200 and rotates synchronously with the character plate 200. The Hall sensor 320 is mounted on one side of the sensing magnet 310. In this application, the Hall sensor 320 is mounted on the circuit board 500. The Hall sensor 320 is used to record the initial position of the sensing magnet 310, the coordinate position of each character relative to the initial position, and the coordinate position of the light-transmitting hole 110 relative to the initial position. When the coordinate position of the light-transmitting hole 110 is fixed and the character plate 200 rotates, the position sensing component 300 can calculate the corresponding character within the light-transmitting hole 110. The position sensing component 300 is connected to the circuit board 500 and is used to transmit the executed character information within the light-transmitting hole 110 to the circuit board 500.

[0095] In one embodiment, the position sensing component 300 can determine that the executed character is the character that the operator subjectively desires to execute only after the character board 200 stays for a fixed period of time.

[0096] Please refer to the attached Figure 3 or attached Figure 4 As shown, the control device of the present application also includes a control body 400, which is used to execute the control instructions for the execution character. The control body 400 is connected to the circuit board 500. After the position sensing component 300 sends the information of the execution character to the circuit board 500, the circuit board 500 finds the control instruction corresponding to the information of the execution character and associates the control instruction with the control body 400. The operator controls the control body 400 through the control means to make the control body 400 execute the control instruction corresponding to the execution character.

[0097] In this application, manipulation means include touch, gesture, voice, etc.

[0098] Please refer to the attached Figure 3 or attached Figure 4 As shown, in this application, the control body 400 includes a middle plate 410 and an execution switch 420. The middle plate 410 is arranged along the second direction Y. The middle plate 410 is provided with a cover plate 100 and an execution switch 420 at each end along the second direction Y. The operator manipulates the cover plate 100 and the middle plate 410 to move up and down, thereby driving the execution switch 420 to turn on and off, thereby executing the control command. In this application, if the control command is to adjust the temperature to increase, then turning on the execution switch 420 once can indicate a temperature increase of 0.5°C or 1°C.

[0099] In one embodiment, the actuator switch 420 includes an elastic member 421. A first end of the elastic member 421 abuts against the middle plate 410, and a second end of the elastic member 421 abuts against the circuit board 500. The actuator switch 420 also includes a first contact point 422 and a second contact point 423. The first contact point 422 and the second contact point 423 are spaced apart along the second direction Y. The first contact point 422 moves synchronously with the middle plate 410, while the second contact point 423 is located on the circuit board 500. During operation, the operator presses down on the cover 100, simultaneously moving the middle plate 410 and the first contact point 422 downward until the first contact point 422 contacts the second contact point 423, thereby closing the actuator switch 420 and compressing the elastic member 421. Furthermore, when the operator releases the cover 100, the compressive force of the elastic member 421 causes the first contact point 422 to break contact with the second contact point 423, thus opening the actuator switch 420.

[0100] In one embodiment, the elastic member 421 is a spring or elastic rubber.

[0101] Please refer to the attached Figure 3 or attached Figure 4 As shown, the control device of the present application further includes an illumination assembly 800, which corresponds to the light-transmitting hole 110. The character plate 200 is disposed between the illumination assembly 800 and the cover plate 100. The illumination assembly 800 emits illumination light that passes through the transparent side surface 220 of the side surface group of the character plate 200, thereby illuminating the execution character and displaying it within the light-transmitting hole 110.

[0102] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
