Description

Technical Field

[0001] This application relates to the field of vehicle-mounted switch technology, and more particularly to a control switch and a vehicle. Background Technology

[0002] In the current field of automotive electronic control, push-button switches are important interactive components for vehicle function control, and are widely used in various operations such as air conditioning adjustment, off-road mode control, and camping scenario function control. Existing automotive push-button switches use character pad printing or laser engraving processes to set function characters directly on the surface of switches such as buttons and toggles, clearly indicating the corresponding control function. Once the switch function is completed, it remains fixed and cannot be adjusted according to changes in the usage scenario.

[0003] As users' demands for vehicle usage scenarios become more diversified, the number of functions that need to be integrated into vehicles is also increasing, including air conditioning control, control functions required for specific off-road scenarios, and special functions required for camping scenarios. To achieve the control of these multiple sets of functions, traditional solutions require configuring a corresponding hardware switch for each set of functions, resulting in an increase in the number of hardware switches in the vehicle.

[0004] Existing solutions have several drawbacks: Firstly, the utilization rate of switches is low. In most scenarios, users only need to use frequently used functions, while function switches for specific scenarios such as off-roading and camping remain idle during daily commutes and do not play a practical control role. Secondly, physical switches occupy a large amount of limited space inside the vehicle, increasing the complexity of the interior design, disrupting the overall simplicity of the interior design, and affecting user convenience. Configuring separate physical switches for multiple functions requires additional investment in switch design, manufacturing, and installation costs, increasing vehicle hardware costs and failing to meet users' needs for flexible function switching in different scenarios. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a control switch and a vehicle.

[0007] To achieve the above objectives, in a first aspect, this application provides a control switch, comprising: A scroll, the outer circumferential surface of which is provided with several different markings; A variable resistor is connected to the spool. The rotation of the spool causes the resistance value of the variable resistor to change. Different resistance values ​​correspond to different markings on the spool. A window is positioned above the markings on the scroll, and different markings are displayed within the window by rotating the scroll; A button, which is connected to the rheostat and external circuitry, is used to trigger an electrical signal corresponding to the current resistance value of the rheostat.

[0008] In the above embodiments, the markings on the outer periphery of the scroll and the viewing window form a visual operation. When the scroll rotates, the marking to be triggered can be directly observed through the viewing window, making the operation target clear; the one-to-one correspondence between the markings and the resistance values ​​of the variable resistor allows the function of the button to be adjusted by rotating the scroll and simultaneously changing the resistance value of the variable resistor and the markings displayed in the viewing window, thus expanding the corresponding functions of the button and saving interior space.

[0009] This solution integrates multiple function controls into a single scroll structure by rotating the scroll to change the resistance value of the variable resistor. With the help of a few buttons, multi-function switching can be achieved, reducing the overall size of the switch and the installation space. It is especially suitable for scenarios with high space utilization requirements, such as vehicle center consoles.

[0010] In some embodiments of this application, a first transmission assembly is further included for driving the reel to rotate; the first transmission assembly includes: Adjustment wheel; A first gear, which is coaxially connected to the adjusting wheel; The second gear is fixedly mounted on the inner wall of the spool and meshes with the first gear.

[0011] In the above embodiments, the first transmission component of this application transmits the user's rotation operation of the adjustment wheel to the scroll through gear meshing: simply rotating the adjustment wheel will drive the scroll to rotate synchronously through the meshing of the first gear and the second gear, without direct contact with the scroll. This simplifies the operation and reduces the force required for operation through the size design of the adjustment wheel, thereby improving the convenience of human-computer interaction.

[0012] In some embodiments of this application, the tooth ratio of the first gear to the second gear is set to 1:N, where N≥1.

[0013] In the above embodiments, the gear ratio of this application is 1:N, where N≥1, for speed reduction transmission. That is, the first gear is the driving gear and the second gear is the driven gear. N rotations of the adjusting wheel can drive the scroll to rotate 1 rotation. The transmission relationship transforms the user's coarse operation of the adjusting wheel into fine rotation of the scroll. Only a small rotation of the adjusting wheel is needed to drive the scroll to rotate slowly through gear meshing, avoiding the scroll markings from skipping the viewing window due to the adjusting wheel rotating too fast, and ensuring that each set of markings can be stably and completely aligned with the viewing window.

[0014] In some embodiments of this application, the rheostat is a rotary rheostat, which has a rotating shaft, and the resistance value is changed by rotating the rotating shaft.

[0015] In the above embodiments, the rotary rheostat of this application changes the resistance value by means of the angular displacement of the rotating shaft, which matches the motion of the reel rotating around its own axis. The rotation of the reel can directly or through a second transmission component drive the rotating shaft of the rotary rheostat to rotate synchronously, so that the change in resistance value corresponds to the rotation angle of the reel.

[0016] In some embodiments of this application, a second transmission assembly is further included for realizing the transmission connection between the reel and the rheostat; the second transmission assembly includes: A first bevel gear is coaxially connected to the scroll shaft, and the rotation of the scroll shaft drives the first bevel gear to rotate. The second bevel gear is coaxially connected to the rotating shaft; In this configuration, the first bevel gear meshes with the second bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear, which in turn drives the rotation of the rotating shaft, thereby changing the resistance value of the rheostat.

[0017] In the above embodiments, the bevel gears of this application enable power transmission between intersecting shafts. The first bevel gear is coaxial with the reel, and the second bevel gear is coaxial with the rotating shaft of the rheostat. This allows the rotation direction of the reel to be converted to the required rotation direction of the rheostat's rotating shaft through gear meshing. The direction-conversion capability of the bevel gears eliminates the need for the reel and rheostat to be coaxially arranged. The installation angle and position of both can be adjusted according to the internal space of the control switch, avoiding layout limitations caused by the requirement for coaxiality and increasing the freedom of structural design.

[0018] In some embodiments of this application, a verification component is further included for verifying whether the identifier within the window is fully displayed; the verification component includes: An annular piece, which is coaxially connected to the spool and can rotate together with the spool, has several notches on it, and the notches correspond to markings; A photoelectric switch is provided, which is located on the movement path of the notch when the annular plate rotates. When the notch rotates to the photoelectric switch, the photoelectric light passes through the notch to form a verification signal.

[0019] In the above embodiments, the verification component of this application requires the complete display of the markings within the window as a prerequisite for button operation. Only when the scroll rotates to the point where a certain group of markings is fully within the window will the corresponding notch of the annular plate rotate precisely to the position of the photoelectric switch, allowing the photoelectric light to pass through and form a verification signal; the button only responds to the operation upon receiving this signal; otherwise, even if the button is triggered, it cannot send an electrical signal. This eliminates the risk of user misoperation when the markings are not fully displayed, ensuring that what the user sees is consistent with the actual triggered function.

[0020] In some embodiments of this application, multiple sets of spaced markings are provided on the outer circumferential surface of the scroll. Each set of markings includes sub-markers spaced along its own axial direction, and all markings in the same set are located in the same circumferential position along the circumferential direction of the scroll.

[0021] In the above embodiments, the identifiers of this application are divided into groups and distributed at intervals on the outer circumference of the scroll. Sub-identifiers within the same group are arranged axially and located in the same circumferential position, that is, the identifiers within the same group and those located on the same generatrix of the scroll integrate related functions into one group, such as the air conditioning control group including sub-identifiers for temperature adjustment, fan speed adjustment, etc. Unrelated functions are distinguished by circumferential intervals, such as the air conditioning group and the seat adjustment group being distributed circumferentially. This layout makes the physical distribution of the identifiers consistent with the user's cognitive logic of the functions. When the user rotates the scroll to switch function groups, they can quickly locate the target function category; when viewing sub-identifiers within a group, all related sub-identifiers can be browsed along the axial direction without additional adjustment of the operation direction.

[0022] In some embodiments of this application, the axial length of the window is greater than or equal to the total axial length of a single set of identifiers, such that when the scroll rotates to a preset position, only one set of identifiers is fully displayed in the window. The buttons are arranged at intervals along the axial direction of the window, so that each icon in the window corresponds to a button.

[0023] In the above embodiments, the axial length of the window in this application is greater than or equal to the total axial length of a single set of icons, and the circumferential width only allows one set of icons to be displayed completely. This limits the possibility of multiple sets of icons entering the window simultaneously. It ensures that when the scroll rotates to the preset position, the user can only see one complete set of icons through the window, rather than partial or multiple overlapping sets, avoiding functional misjudgments due to display clutter. Only when the entire set of icons is completely within the window and meets the window size limit will the verification component trigger a signal, making the display and operation logical and avoiding confusion.

[0024] In some embodiments of this application, a positioning component is also included, the positioning component comprising: An elastic element is fixedly mounted on the housing of the control switch, and one end of the elastic element has a protrusion. Positioning grooves are provided on the outer circumferential surface of the roll and are distributed at intervals along the circumferential direction of the roll. The number of positioning grooves corresponds one-to-one with the number of groups of markings. When the scroll rotates to the point where a certain set of markings is fully displayed in the window, the protrusion of the elastic element is embedded in the corresponding positioning groove.

[0025] In the above embodiments, the positioning slots of this application are distributed at intervals along the circumference of the scroll, and their number corresponds one-to-one with the number of groups of markings. The circumferential position of each positioning slot corresponds to the position of a certain group of markings that are fully displayed in the window. When the scroll rotates to the target position, the protrusion of the elastic element is inserted into the corresponding positioning slot under the action of elastic force. The mechanical structure restricts the free rotation of the scroll, making the scroll stably stay in that position. This ensures that the scroll will not deviate from the preset position due to vibration, such as vehicle bumps or accidental slight rotation, and ensures that the markings in the window are always displayed completely and stably, providing a mechanical reference for subsequent verification component triggering and button operation.

[0026] A second aspect provides a vehicle, including a body and the control switch described in the first aspect; the vehicle body is provided with: Multiple functional modules are used to implement the functions on the vehicle; The external circuit is the vehicle's electronic control circuit, used to acquire the resistance value signal of the rheostat and process the signal to match the corresponding functional module. The external circuit is connected to the functional module. When the button is triggered, the external circuit acquires and processes the resistance value signal, and the corresponding functional module works. In the above embodiments, multiple functional modules of the vehicle, such as air conditioning, seat adjustment, and driving modes, are centrally controlled via control switches: simply rotate the scroll to switch the indicator group in the window, and then operate the corresponding button to trigger the target function. This integrated design reduces the number of physical switches in the vehicle, saving space.

[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0036] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0037] It should be noted that in the automotive field, push-button switches are important interactive components for vehicle function control, widely used in various operations such as air conditioning adjustment, off-road mode control, and camping scenario function control. Currently, the function settings of in-vehicle push-button switches are achieved using character pad printing or laser engraving processes. This involves directly printing function characters onto the surface of switches such as buttons and toggles to clearly identify the corresponding control function. Once the switch function is completed, it remains fixed and cannot be adjusted according to changes in the usage scenario.

[0038] As users' demands for vehicle usage scenarios become more diversified, the number of functions that need to be integrated into vehicles is also increasing, including air conditioning control, control functions required for specific off-road scenarios, and special functions required for camping scenarios. To achieve the control of these multiple sets of functions, traditional solutions require configuring a corresponding hardware switch for each set of functions, resulting in an increase in the number of hardware switches in the vehicle.

[0039] Existing solutions have several drawbacks: Firstly, the utilization rate of switches is low. In most scenarios, users only need to use frequently used functions, while function switches for specific scenarios such as off-roading and camping remain idle during daily commutes and do not play a practical control role. Secondly, physical switches occupy a large amount of limited space inside the vehicle, increasing the complexity of the interior design, disrupting the overall simplicity of the interior design, and affecting user convenience. Configuring separate physical switches for multiple functions requires additional investment in switch design, manufacturing, and installation costs, increasing vehicle hardware costs and failing to meet users' needs for flexible function switching in different scenarios.

[0040] Based on this, this application proposes a control switch and a vehicle. By using a marked reel, a rheostat that rotates with the reel, a display window for markings, and a button for triggering signals, the signal matching between the switch and the functional module is achieved through the vehicle's external circuit. This realizes integrated control of multiple functions by a single switch, solving the problems of traditional distributed switches being complex to operate, occupying a large space, prone to false triggering due to ambiguous positioning, and difficult to adapt to the complex environment of a vehicle.

[0041] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0042] As attached Figures 1 to 4 As shown, in the first aspect of this application, a control switch is provided, including a scroll 1, a rheostat 2, a window 3, and a button 31. Several different markings 11 are provided on the outer circumference of the scroll 1 to identify the function corresponding to each marking 11. The rheostat 2 is connected to the scroll 1, and the rotation of the scroll 1 causes a change in the resistance value of the rheostat 2; different resistance values ​​correspond to different markings 11 on the scroll 1. The window 3 is located above the markings 11 on the scroll 1, and rotating the scroll 1 adjusts the display of different markings 11 within the window 3. The button 31 is connected to the rheostat 2 and an external circuit 6, and is used to trigger an electrical signal corresponding to the current resistance value of the rheostat 2. It should be noted that the rheostat 2 is an electrical rheostat 2; by adjusting the rheostat 2, the resistance change of the rheostat 2 can be adjusted.

[0043] The markings 11 on the outer periphery of the scroll 1 work in conjunction with the window 3 to form a visual operation. When the user rotates the scroll 1, they can directly observe the marking 11 that is about to be triggered through the window 3, making the operation target clear. The one-to-one correspondence between the markings 11 and the resistance value of the rheostat 2 allows the user to adjust the function of the button 31 by rotating the scroll 1, which synchronously changes the resistance value of the rheostat 2 and the markings 11 displayed in the window 3, thereby expanding the corresponding functions of the button 31.

[0044] This solution integrates multiple function controls into a single scroll 1 structure by rotating the scroll 1 to change the resistance value of the rheostat 2. With the help of a few buttons 31, multi-function switching can be achieved, reducing the overall size and installation space of the switch. It is especially suitable for scenarios with high space utilization requirements, such as vehicle center consoles.

[0045] In some embodiments, new functions can be extended through the same switch structure simply by adding a new function identifier 11 to the reel 1 and setting a specific resistance value for the rheostat 2 accordingly, without redesigning the overall circuit or mechanical structure; at the same time, by adapting to the external circuit 6, the switch can be associated with different types of functional modules 7, making it highly versatile.

[0046] In some embodiments, the control switch further includes a first transmission assembly 4 for driving the reel 1 to rotate; the first transmission assembly 4 includes an adjusting wheel 43, a first gear 41, and a second gear 42. The adjusting wheel 43 is used for manual adjustment by the user. The first gear 41 is coaxially connected to the adjusting wheel 43. The second gear 42 is fixedly disposed on the inner wall of the reel 1, and the second gear 42 meshes with the first gear 41.

[0047] The first transmission component 4 transmits the user's rotation operation of the adjusting wheel 43 to the scroll 1 through gear meshing. Simply rotating the adjusting wheel 43 will drive the scroll 1 to rotate synchronously through the meshing of the first gear 41 and the second gear 42, without direct contact with the scroll 1. This simplifies the operation and reduces the force required for operation through the size design of the adjusting wheel 43, thus improving the convenience of human-computer interaction.

[0048] In some embodiments, the tooth ratio of the first gear 41 to the second gear 42 is set to 1:N, where N≥1.

[0049] The gear ratio is 1:N, where N≥1, used for speed reduction transmission. The first gear 41 is the driving gear, which is an external gear. The second gear 42 is the driven gear, which is an internal gear. The external gear drives the internal gear. N rotations of the adjusting wheel 43 will drive the scroll 1 to rotate once. This transmission relationship transforms the user's coarse operation of the adjusting wheel 43 into a fine rotation of the scroll 1. Only a small rotation of the adjusting wheel 43 is needed to slowly rotate the scroll 1 through gear meshing, preventing the markings 11 on the scroll 1 from skipping the viewing window 3 due to excessive rotation of the adjusting wheel 43, ensuring that each set of markings 11 is stably and completely aligned with the viewing window 3.

[0050] In some embodiments, the first transmission assembly 4 includes an adjusting wheel 43, which can be coaxially arranged with the scroll 1 and fixed on the scroll 1. By adjusting the diameter of the adjusting wheel 43, the precision adjustment of the scroll 1 by the adjusting wheel 43 can be controlled.

[0051] In some embodiments, the rheostat 2 is a rotary rheostat 2, which is provided with a rotating shaft, and the resistance value is changed by rotating the rotating shaft.

[0052] The rotary rheostat 2 changes the resistance value by rotating its shaft at an angular displacement, matching the motion of the spool 1 rotating around its own axis. The rotation of the spool 1 can directly or through the second transmission assembly 5 drive the rotary rheostat 2 to rotate synchronously, so that the change in resistance value corresponds to the rotation angle of the spool 1.

[0053] In some embodiments, the control switch further includes a second transmission assembly 5 for transmitting power between the spool 1 and the rheostat 2. The second transmission assembly 5 includes a first bevel gear 51 and a second bevel gear 52. The first bevel gear 51 is coaxially connected to the spool 1, and rotation of the spool 1 drives rotation of the first bevel gear 51. The second bevel gear 52 is coaxially connected to a rotating shaft. The first bevel gear 51 and the second bevel gear 52 mesh; rotation of the first bevel gear 51 drives rotation of the second bevel gear 52, and rotation of the second bevel gear 52 drives rotation of the rotating shaft, thereby changing the resistance value of the rheostat 2.

[0054] The bevel gears enable power transmission between intersecting shafts. The first bevel gear 51 is coaxial with the reel 1, and the second bevel gear 52 is coaxial with the rotating shaft of the rheostat 2. This allows the rotation direction of the reel 1 to be converted to the required rotation direction of the rheostat 2's rotating shaft through gear meshing. The bevel gears' ability to change direction eliminates the need for the reel 1 and rheostat 2 to be coaxially arranged. Their installation angle and position can be adjusted according to the internal space of the control switch, avoiding layout limitations caused by the requirement for coaxiality and increasing the freedom of structural design.

[0055] In some embodiments, the relationship between the rotation angle of the reel 1 and the angle of the rotary rheostat 2 can be adjusted by adjusting the transmission ratio of the first bevel gear 51 and the second bevel gear 52, so as to achieve more precise angle adjustment and adapt to the on-site working conditions.

[0056] In some embodiments, the second transmission component 5 may be configured as a spur gear transmission component, a helical gear transmission component, a herringbone gear transmission component, or a gear belt drive, and different transmission components can be adapted to different working conditions.

[0057] In some embodiments, the control switch further includes a verification component for verifying whether the mark 11 in the window 3 is fully displayed; the verification component includes an annular plate 12 and a through-beam switch 14. The annular plate 12 is coaxially connected to the scroll 1 and can rotate with the scroll 1. The annular plate 12 is provided with a plurality of notches 13, and the notches 13 correspond to the mark 11. The through-beam switch 14 includes a transmitting end and a receiving end, which are respectively disposed on both sides of the annular plate 12 and located on the movement path of the notches 13 when the annular plate 12 rotates. When the scroll 1 rotates to the point where the mark 11 is fully displayed in the window 3, the corresponding notch 13 of the annular plate 12 rotates to the through-beam switch 14, and the light emitted by the transmitting end passes through the notch 13 and is received by the receiving end, forming a verification signal; the button 31 can only respond to the button 31 operation and send an electrical signal when the verification signal is received.

[0058] The verification component requires the complete display of the identifier 11 within the window 3 as a prerequisite for button operation. Only when the scroll 1 rotates until a set of identifiers 11 is fully within the window 3 will the corresponding notch 13 of the annular plate 12 rotate precisely to the position of the through-beam switch 14, allowing the through-beam light to pass through and form a verification signal. The button only responds to the operation upon receiving this signal; otherwise, even if the button 31 is triggered, it cannot send an electrical signal. This avoids the risk of user misoperation when the identifier 11 is not fully displayed, ensuring that what the user sees matches the actual triggered function.

[0059] In some embodiments, multiple sets of spaced-apart markings 11 are provided on the outer circumferential surface of the scroll 1. Each set of markings 11 includes sub-markers 11 spaced-apart along its own axial direction. All markings 11 in the same set are located in the same circumferential position along the circumferential direction of the scroll 1.

[0060] The labels 11 are grouped and spaced out on the outer circumference of the scroll 1. Sub-labels 11 within the same group are arranged axially and share the same circumferential position. That is, labels 11 within the same group and those located on the same generatrix of the scroll 1 integrate related functions into one group. For example, the air conditioning control group includes sub-labels 11 for temperature adjustment, fan speed adjustment, etc. Unrelated functions are distinguished by circumferential spacing. For example, the air conditioning group and the seat adjustment group are distributed circumferentially. This layout ensures that the physical distribution of the labels 11 is consistent with the user's cognitive logic of the functions. When the user rotates the scroll 1 to switch function groups, they can quickly locate the target function category. When viewing sub-labels 11 within a group, all related sub-labels 11 can be viewed along the axial direction without the need for additional adjustment of the operation direction.

[0061] In some embodiments, the axial length of the window 3 is greater than or equal to the total axial length of a single set of identifiers 11, such that when the scroll 1 rotates to a preset positioning position, only one set of identifiers 11 is fully displayed in the window 3. The buttons 31 are arranged at intervals along the axial direction of the window 3, so that each identifier 11 in the window 3 is close to the button 31 corresponding to its function.

[0062] The axial length of window 3 is greater than or equal to the total axial length of a single set of icons 11, and its circumferential width only allows one set of icons 11 to be fully displayed. The size of window 3 limits the possibility of multiple sets of icons 11 entering window 3 simultaneously. This ensures that when scroll 1 rotates to the preset positioning position, the user can only see one complete set of icons 11 through window 3, rather than partial or overlapping sets, avoiding functional misjudgments due to display clutter. Only when the entire set of icons 11 is fully within window 3, meeting the size limitations of window 3, will the verification component trigger a signal, ensuring logical display and operation and preventing confusion.

[0063] In some embodiments, the control switch further includes a positioning component, which includes an elastic element and a positioning groove 15. The elastic element is fixedly mounted on the housing of the control switch, and one end of the elastic element has a protrusion. Specifically, the elastic element can be a spring pin or a spring ball structure, with one end of the spring fixedly mounted on the outer housing and the other end of the spring fixed with a pin structure or a ball. The positioning grooves 15 are disposed on the outer circumferential surface of the scroll 1 and are spaced apart along the circumferential direction of the scroll 1. The number of positioning grooves 15 corresponds one-to-one with the number of groups of markings 11. When the scroll 1 rotates until a certain group of markings 11 is fully displayed in the viewing window 3, the pin of the elastic element is embedded in the corresponding positioning groove 15.

[0064] It should be noted that the elastic element has deformable characteristics. When the user actively rotates the scroll 1 by transmitting force through the adjusting wheel 43 and the first transmission component 4, the applied torque can overcome the elastic force of the elastic element, causing the protrusion to disengage from the current positioning groove 15. This avoids switching difficulties caused by excessively tight locking of the positioning structure and ensures smooth operation: when the user rotates the adjusting wheel 43, the protrusion slides out of the positioning groove 15 as the scroll 1 rotates. After elastic deformation, it re-embeds in the new positioning groove 15 and forms a locking feedback, achieving a balance between positioning and switching.

[0065] Positioning slots 15 are spaced apart along the circumference of the scroll 1, and their number corresponds one-to-one with the number of groups of markings 11. The circumferential position of each positioning slot 15 corresponds to the position of a certain group of markings 11 fully displayed on the scroll 1 within the viewing window 3. When the scroll 1 rotates to the target position, the protrusion of the elastic element is inserted into the corresponding positioning slot 15 under the action of elastic force. The mechanical structure restricts the free rotation of the scroll 1, making the scroll 1 stably stay at that position. This ensures that the scroll 1 will not deviate from the preset position due to vibration, such as vehicle bumps or accidental slight rotation, and ensures that the markings 11 within the viewing window 3 are always fully and stably displayed, providing a mechanical reference for subsequent verification component triggering and button 31 operation.

[0066] In some embodiments, the outer peripheral surface of the scroll 1 is configured as a polygonal prism, and the functional text is respectively disposed on each side of the polygonal prism.

[0067] The polygonal prism has clearly defined side boundaries, with each side independently supporting a set of functional text, and there are angular transitions between adjacent sides. This forms a partition where a set of text corresponds to a fixed side, ensuring that the circumferential position of the functional text matches the rotation angle of the scroll 1. For example, each side of the regular hexagonal prism corresponds to a 60° rotation range. When the elastic protrusion and positioning groove 15 are in position, when the scroll 1 rotates to a point where a certain side faces the viewing window 3, the protrusion can be inserted into the corresponding positioning groove 15. This avoids the offset problem of half-set display of functional text caused by the arc transition of the cylindrical surface, ensuring that the functional text of a single side is always fully displayed within the viewing window 3.

[0068] like Figure 4 As shown, the second aspect of this application provides a vehicle, including a body and a control switch as described in the first aspect; multiple functional modules 7 and an external circuit 6 are provided on the vehicle body. The multiple functional modules 7 are used to implement functions on the vehicle. The external circuit 6 is the vehicle's electronic control circuit, used to acquire the resistance value signal of the variable resistor 2, process the signal to match the corresponding functional module 7, and is connected to the functional module 7. When the button 31 of the control switch is triggered, the external circuit 6 acquires and processes the current resistance value signal of the variable resistor 2, and opens / closes the display window 3 showing the functional module 7 corresponding to the identifier 11 within the display area.

[0069] Multiple functional modules 7 of the vehicle, such as air conditioning adjustment, seat adjustment, and driving modes, are centrally controlled via control switches: simply rotate the scroll 1 to switch the 11 groups of icons in the window 3, and then operate the corresponding button 31 to trigger the target function. This integrated design reduces the number of physical switches in the vehicle, saving space.
