Description

Technical Field

[0001] This utility model relates to a column-shaped multi-functional switch unit and a multi-functional switch module having the same, which are as follows: by simplifying the structure, the design freedom is improved, and the effect of reducing costs and saving manufacturing expenses is enhanced. Background Technology

[0002] The mobility of cars and other vehicles has transcended their function as transportation tools. Consumers are increasingly demanding various conveniences to provide users with a more stable and comfortable driving experience.

[0003] Generally, for security and safety reasons, vehicles are equipped with starting devices, including a starter switch, engine starter unit, ignition coil, and distributor installed inside the vehicle. In particular, the starter switch not only controls the starting of the engine but also controls the supply of starting power to other electrical equipment.

[0004] Furthermore, essential vehicle functions, such as gear shift levers for changing gears, can be converted into mechanical-electronic switches or electronic switches. These switching devices, depending on their type, have advantages and disadvantages in terms of durability, operability, and the operational awareness derived from operability.

[0005] However, as these are vehicle-use devices, durability and the ability to perceive the operating status through user operation are emphasized. However, existing switch structures are structurally limited, leading to problems such as excessively large component spaces or operational inconvenience. In particular, because each component is individually configured for its own operation, it is difficult to achieve a compact switching device. With the electrification of automobiles, these switches have adopted integrated structures, and these vehicle-use switching devices have adopted the form of composite switches to achieve multiple function selections.

[0006] However, in existing technologies, when using a composite switch, multiple substrates are required to configure each switch sensor, thus reducing the configuration space and constraining the assembly process. Furthermore, the use of multiple substrates leads to increased process costs and manufacturing expenses. Utility Model Content

[0054] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. First, when labeling the constituent elements in the drawings, the same reference numerals will be used as much as possible for the same constituent elements, even if they are shown in different drawings. Furthermore, in the process of describing the present invention, detailed descriptions of related well-known structures or functions will be omitted if it is determined that such detailed descriptions may obscure the spirit of the present invention.

[0055] According to an embodiment of the present invention, a multi-functional switch unit 10 includes a plurality of switch units 300 and 500. In this embodiment, the multi-functional switch unit 10 is a column switch type disposed on the side of the vehicle steering wheel SW, and mainly describes the case including a gear selection switch for selecting the vehicle's gear and a start switch.

[0056] The multifunctional switching unit 10 of this invention includes multiple switching units 300 and 500. At least a portion of each of the multiple switching units is disposed on a substrate 200. That is, for the multiple switching units 300 and 500, the multifunctional switching unit 10 transmits electrical signal current to a single substrate. In other words, by using a common substrate for multiple switching units 300 and 500, the design is simplified, the internal configuration is simplified, and manufacturing costs are reduced.

[0057] More specifically, according to an embodiment of the present invention, the multi-functional switch unit 10 includes a housing 100. The housing 100 is configured to connect to the lower side of the steering wheel SW and adopts a column switch type. The housing 100 includes a housing cover 110 and a housing body 120. The housing cover 110 and the housing body 120 interlock to form an internal space, in which other constituent elements are stably disposed.

[0058] The outer surface of the outer cover 110 is decorated with icons representing the vehicle's gear shift positions, such as D, N, R, and P. Various options are available for these icons, such as further incorporating other features for illuminating the interior.

[0059] The housing cover 110 and the housing body 120 are internally configured with a substrate 200. Multiple sensing elements of switching units 300 and 500 are configured on the substrate 200. The substrate 200 is configured to transmit signals to a single substrate, thereby eliminating complex structures. By using a single substrate, manufacturing costs and configuration space are minimized, and assemblability is also improved.

[0060] Multiple switching units include a composite switch section 300 and a push-button switch section 500. The composite switch section 300 is composed of a switch section that implements a composite sensing function, sensing shaft rotation centered on an axis located in at least a portion of the housing 100 and shaft movement along the length of the axis. In this embodiment, the composite switch section 300 is composed of a gear selection switch section. The push-button switch section 500 is configured such that one end is exposed from the outer peripheral surface of the housing 100, and the push-button switch section 500 is composed of an SSB (Start-Stop-Button) serving as a start switch section.

[0061] First, the composite switch unit 300, which is composed of a gear selector switch unit, includes a composite knob 310, a composite sensing bracket unit 340, a composite sensing operation unit 320, and a composite sensing fixing unit 330.

[0062] The composite knob 310 is disposed on the outside of the housing 100. The composite sensing support 340 can rotate or move along the axis as the composite knob 310 is operated. The composite sensing operation unit 320 is disposed on the composite sensing support 340. The composite sensing fixing unit 330 is located on the substrate 200, corresponding to the position of the composite sensing operation unit 320, thereby sensing the operating state of the composite sensing operation unit 320.

[0063] More specifically, in the composite switch section 300, the composite knob 310 is configured to be positioned outside the housing 100 so as to allow for relative operation. Specifically, the composite knob 310 includes a composite rotary knob 311 and a composite axial knob 313.

[0064] Composite rotary knob 311 (reference) Figure 14 The compound rotary knob 311 is disposed at one end of the housing 100 and is configured to be rotatable. The compound rotary knob 311 is disposed at one end of the housing 100, and is configured to be rotatable relative to the housing 100, so that the compound rotary knob 311 rotates along line II (refer to...). Figure 4 as well as Figure 5 The axis rotation is achieved by centering on the axis.

[0065] The composite rotary knob 311 rotates around line II as its central axis, but it may also include components for achieving stable rotation. A rotary knob guide 3111 is located on one side of the composite rotary knob 311, and the housing 100 also includes a housing rotation guide 130. The housing rotation guide 130 is located on the side of the housing cover 110 and the housing body 120 of the housing 100. The housing rotation guide 130 and the rotary knob guide 3111 engage in a manner that allows for relative rotation. This engagement structure allows the composite rotary knob 311 to rotate smoothly relative to the housing 100, preventing accidental separation or detachment.

[0066] In this embodiment, although not specifically described, other limiters can be provided on the housing rotation guide 130 and the rotary knob guide 3111 to limit the relative rotation angle range. Furthermore, various modifications are possible; for example, other locking elements can be provided on the housing rotation guide 130 and the rotary knob guide 3111 to provide a predetermined stopping structure when the composite rotary knob 311 rotates relative to the housing 100.

[0067] On the other hand, a composite axial knob 313 is disposed at the end of the composite rotary knob 311. The composite axial knob 313 is configured to operate along the length of the rotation axis of the composite rotary knob 311. A rotary knob support hole 3113 is formed in the center of the composite rotary knob 311. The rotary knob support hole 3113 extends through the rotation axis of the composite rotary knob 311 along its length. The sensing bracket 350 of the composite sensing bracket portion 340, described later, is disposed through the rotary knob support hole 3113. The composite sensing bracket portion 340 can rotate or move along its axis following the operation of the composite knob 310. The sensing bracket 350 of the composite sensing bracket portion 340 is configured to operate through the rotary knob support hole 3113, thereby enabling a predetermined push-switching action along the length of the axis.

[0068] The composite sensing support 340 includes a sensing support 350 and a sensing elastic part 360. A composite sensing operation part 320 is disposed on the sensing support 350, and the sensing support 350 is capable of relative operation with respect to at least a portion of the composite knob 310. That is, as described later, the sensing support 350 can be structured to be capable of relative operation with respect to at least a portion of the composite knob 310 along the axial length direction of line II.

[0069] A sensing elastic part 360 is disposed on the composite rotary knob 311. One end of the sensing elastic part 360 is elastically supported on the side of the composite rotary knob 311, and the other end of the sensing elastic part 360 contacts and is elastically supported on the side of the sensing bracket 350 and the composite axial knob 313. With this configuration, after the external force applied to the composite axial knob 313 and the sensing bracket 350 is removed, they can return to their original positions.

[0070] The sensing bracket 350 includes a bracket body 351, a bracket connecting shaft 353, and a bracket support 355. The bracket body 351 is configured such that one side is open in the direction of the rotation axis of line II, thereby accommodating the composite sensing operation unit 320. The bracket connecting shaft 353 is connected to the other side of the bracket body 351. One end of the bracket connecting shaft 353 is connected to the bracket body 351, and the other end of the bracket connecting shaft 353 is disposed towards the composite axial knob 313.

[0071] The bracket support 355 is connected to the other end of the bracket connecting shaft 353 and is configured to move relative to the housing 100. The bracket support 355 is disposed in the aforementioned rotary knob support hole 3113 and can realize movement along the length direction of the axis indicated by line II.

[0072] At this point, based on this technology, it can be clearly understood that the bracket support 355 and the rotary knob support hole 3113 form corresponding cross-sectional structures, thereby adopting a structure to prevent interference that occurs during the relative operation between the two.

[0073] Furthermore, preferably, the bracket support 355 of this invention adopts a non-circular cross-sectional structure. That is, the bracket support 355 and the rotary knob support hole 3113 form a non-circular cross-sectional structure, thereby preventing relative rotation between the composite rotary knob 311 and the composite sensing bracket 340 when the composite sensing bracket 340, which is equipped with the composite switch sensing operation unit 320, rotates about line II as the axis.

[0074] In this embodiment, the bracket support 355 and the rotary knob support hole 3113 are shown to have a square cross-sectional structure with chamfered edges. However, within the range of forming a cross-sectional structure that prevents relative rotation, the cross-sections of the bracket support 355 and the rotary knob support hole 3113 can be selected in various ways. For example, the cross-sections of the bracket support 355 and the rotary knob support hole 3113 can also be elliptical, rectangular, or polygonal.

[0075] The other end of the bracket support 355 is connected to the side of the composite axial knob 313. In some cases, the end of the bracket support 355 forms a bracket elastic support 357, which contacts the other end of the aforementioned sensing elastic part 360, thereby providing elastic support for the sensing elastic part 360. In this case, a bracket elastic support hook-up portion is formed from the end to the side of the bracket elastic support 357, thereby achieving an interlocking connection with the composite axial knob 313. The composite axial knob 313 includes an axial knob body 3131 and an axial knob body limiter 3133.

[0076] An axial knob body limiter 3133 extends outward from the side of the axial knob body 3131. The axial knob body limiter 3133 can engage with the rotary knob limiter formed at the end of the compound rotary knob 311, thereby preventing the axial knob body 3131 from accidentally separating and falling off from the compound rotary knob 311.

[0077] The composite sensing operation unit 320 and the composite sensing fixing unit 330 can sense the switching action of the composite switch unit 300 and output a switching signal. The composite sensing operation unit 320 is disposed on the composite sensing bracket unit 340. When the user rotates and applies pressure from the composite rotary knob 311 to the composite axial knob 313, the composite sensing operation unit 320 disposed on the composite sensing bracket unit 340 also rotates to the operating state, resulting in a position change. At this time, the composite sensing fixing unit 330 is disposed on one side of the substrate 200, and senses the position change when the composite sensing operation unit 320 rotates and runs.

[0078] In this embodiment, the composite sensing operation unit 320 is composed of a magnet, and the composite sensing fixing unit 330 is composed of a magnetic sensor, including a Hall sensor or the like that senses the operation state of the composite sensing operation unit 320, i.e., changes in position and outputs a signal of change.

[0079] That is, when the composite rotary knob 311 and composite axial knob 313 are rotated and pressurized under the operation of the user, the composite sensing operation unit 320 configured in the composite sensing bracket 340 also rotates and runs, realizing a position change. This position change generates a magnetic field change. The composite sensing fixing unit 330, which is composed of Hall sensors, senses the magnetic field change and can output a predetermined switching action signal.

[0080] The composite sensing fixing part 330 of this utility model can be a single unit, but according to this utility model, there can be multiple composite sensing fixing parts 330. This provides a redundant and stable operating structure based on such a multiple configuration structure. That is, through the configuration structure of multiple composite sensing fixing parts 330, when an error occurs in one composite sensing fixing part 330, a stable switching operating structure can be formed using the output signals of the other composite sensing fixing parts 330.

[0081] On the other hand, with multiple composite sensing fixing parts 330 configured in this way, the multiple composite sensing fixing parts 330 and the composite sensing operation part 320 of this utility model can form a mechanical relationship and be adjusted.

[0082] That is, according to an embodiment of the present invention, the composite sensing operation unit and the composite sensing fixing unit, such as Figure 8 as well as Figure 10 As shown, a symmetrical positional relationship can sometimes be formed relative to the rotation axis, i.e. line II, of the composite sensing operation unit 320.

[0083] Without the application of external force, on the plane perpendicular to the axis of rotation of the composite sensing operation unit 320, the distance between the axis rotation center of the composite sensing operation unit 320 and the plurality of composite sensing fixing units 330 is the same.

[0084] exist Figure 10 The figure shows a simplified side cross-sectional view perpendicular to line II. In the figure, the composite sensing operation unit 320 adopts a circular configuration structure and is positioned at the rotation center of the rotational action, i.e., line AA.

[0085] At this time, two composite sensing fixing parts 330 are disposed on the substrate 200, in Figure 10On the side, the center lines of each composite sensing fixing part 330 are represented as lines O1-O1 and O2-O2, and the distances between lines O1-O1, O2-O2 and line AA all have the same distance interval indicated by the reference numeral w. This symmetrical positional relationship ensures stable sensing function.

[0086] Figure 8 as well as Figure 9 A diagram showing the substrate 200 viewed from a top-down perspective is provided. Figure 8 as well as Figure 9 In the figure, the position of the composite sensing operation unit 320 is projected onto the area indicated by reference numeral AM. When the composite sensing operation unit 320 is projected onto the substrate 200, at least a portion of the composite sensing fixing part 330 overlaps with the projection area of ​​the composite sensing operation unit 320. Furthermore, line OO represents the center line of the composite sensing operation unit 320 before the pressure applied by the user's pushing action to the composite axial knob 313, line CC represents the center line of the composite sensing fixing part 330, and line O'-O' represents the center line of the composite sensing operation unit 320 after the pressure applied by the user's pushing action to the composite axial knob 313 has shifted by an amount equivalent to a movement distance d.

[0087] That is, when the composite sensing operation unit 320 moves by pushing the composite axial knob 313, the projection area of ​​the composite sensing operation unit 320, indicated by reference numeral AM, becomes an area that overlaps with the composite sensing fixing unit 330, thereby the composite sensing fixing unit 330 senses the change in magnetic field formed by the composite sensing operation unit 320 and outputs a sensing signal.

[0088] On the other hand, as described above, the composite sensing fixing part 330 of this utility model is not limited to Figure 10 The structure is symmetrically arranged on the sides.

[0089] On a plane perpendicular to the axis of rotation of the composite sensing operation unit 320, the distance between the axis rotation center of the composite sensing operation unit 320 and the plurality of composite sensing fixing units 330 can be different. For example... Figure 11 As shown, the composite sensing fixing part 330 of this utility model adopts a structure in which the center line O1-O1 of one composite sensing fixing part 330 is aligned with the center line AA of the composite sensing operation part 320, while the center lines O2-O2 of the other composite sensing fixing parts are separated from the center line AA of the composite sensing operation part 320. Thus, even when the two composite sensing operation parts 320 are not subjected to external force, they can output different sensing signals.

[0090] Figure 12 as well as Figure 13 It shows Figure 11The embodiment is shown in top view projection. That is, the position of the composite sensing operation unit 320 projected onto the substrate 200 is projected onto the area indicated by reference numeral AM. Line CC represents the center line of the composite sensing fixing unit 330, and lines OO and O'-O' represent the center line of the composite sensing operation unit 320 before and after the composite axial knob 313 is applied by the user's pushing action and pressure. Figure 12 The diagram shows the state when no external force is applied. Figure 13 A simplified planar view is shown with the compound axial knob 313 in a state where an external force is applied by the user. In the state without an applied external force, line CC and line OO are separated, and line CC and line O'-O' are also further separated. Undoubtedly, various design variations are possible; for example, the spacing between line CC and line O'-O' can be smaller than the spacing between line CC and line OO.

[0091] With this configuration, the composite switch unit 300 can sense changes in the rotational position of the shaft and changes in the position along the shaft's length. The normal to one side of the substrate 200 can be configured to be orthogonal to the axis of rotation of the composite sensing and operating unit 320. With this configuration, when the composite axial knob 313 of the composite switch unit 300 is in linear motion, a certain distance relationship is maintained with one side of the substrate 200, thereby keeping the distance between the substrate 200 and the composite switch sensing and fixing unit 330 constant according to the linear position change of the composite switch sensing and operating unit 320 disposed on the sensing bracket 350.

[0092] The multifunctional switch unit 10 of this invention may also include constituent elements capable of continuously and stably forming and maintaining this uniform linear distance. The housing 100 may also include a housing support guide 140. The housing support guide 140 may extend from one side of the housing cover 110 and / or the housing body 120 of the housing 100, and the housing support guide 140 has a structure that can contact and support at least one side of the composite sensing bracket 340, thereby guiding the axial movement of the composite sensing bracket portion 340. For example... Figure 20 As shown, a structure can be adopted in which the support connecting shaft 353 of the sensing bracket 350 of the composite sensing bracket 340 contacts and rotatably supports the housing bracket guide 140, such as... Figure 21 As shown, the sensing bracket 350 may also have a sensing bracket extension 359.

[0093] Sometimes, the housing support guide 140 may extend from the housing body 120, penetrate the substrate 200, and extend toward the sensing support 350. The housing support guide 140 contacts the support body extension 359 and supports the sensing support 350. The support body extension 359 extends and is formed at the end of the support body 351.

[0094] On the other hand, while the above embodiments illustrate a case where the composite sensing operation unit is a magnet, the composite sensing operation unit 320a of this invention may sometimes also include a strong magnet. That is, as shown in the example... Figure 16 As shown, the composite sensing operation unit 320a includes a composite sensing operation protrusion 321a. The composite sensing fixing unit 330 senses the rotation w and position change d of the composite sensing operation protrusion 321a, and senses and outputs the signal change.

[0095] On the other hand, the button switch part 500 of this utility model includes a button switch knob 510, a button switch sensing and fixing part 520, and a button switch sensing and running part 530.

[0096] The push-button switch knob 510 is configured to be exposed outside the housing 100. A push-button switch sensing and fixing portion 520 is disposed on the substrate 200, and one end of a push-button switch sensing and operating portion 530 is disposed on the bottom surface of the push-button switch knob 510. The other end of the push-button switch sensing and operating portion 530 generates a signal change in the push-button switch sensing and fixing portion 520. That is, in this embodiment, the push-button switch sensing and fixing portion 520 is composed of a push switch that operates by a pushing action. The applied pressure transmitted through the push-button switch knob 510 is transmitted to the push-button switch sensing and fixing portion 520 through the push-button switch sensing and operating portion 530, thereby generating a predetermined electrical signal change and transmitting the changed switching signal to the vehicle's main control unit (not shown), thereby transmitting predetermined start-up state information.

[0097] The multi-functional switch unit 10 of this invention may also include a light output component for guiding the operation position of the push-button switch unit 500 or notifying the operation preparation status and whether or not operation is required. The multi-functional switch unit 10 includes a switch light source unit 600, which generates and provides light output through the push-button switch unit 500.

[0098] like Figure 17 as well as Figure 18 As shown, the switchable light source unit 600 is disposed on the substrate 200. Figure 17 The push-button switch sensing and fixing part 520 of the push-button switch part 500 shown is configured as a rubber pad, but this utility model is not limited to this and can be configured in various ways, such as forming a non-contact magnet. Figure 17 In this configuration, a portion of the rubber pad is exposed, and a switch light source portion 600 formed on one side of the substrate 200 is disposed through the center of the interior of the push-button switch sensing and operating portion 530 connected to the lower end of the push-button switch knob 510. Light emitted from the switch light source portion 600 passes through the through-hole in the center of the push-button switch sensing and operating portion 530 and illuminates the push-button switch icon 511 formed on the push-button switch knob 510, thereby enabling the execution of a predetermined light output function.

[0099] In the above embodiments, the internal separation distance between the substrate 200 and the housing 100 can be the same at the location of the push-button switch portion 500 and the location of the composite switch portion 300, and the internal separation distance between the substrate 200 and the housing 100 can also be different at the locations of the push-button switch portion 500 and the composite switch portion 300. This design freedom allows for various modifications to the design configuration of the push-button switch portion 500 and the exposed surface.

[0100] Furthermore, in the aforementioned embodiments, the substrate 200 is located inside the housing 100 and is configured separately from the exposed portion of the push-button switch portion 500. At least a portion of the composite switch portion 300 is disposed within the space between the substrate 200 and the exposed portion of the push-button switch portion 500. With the substrate 200 disposed on the inner bottom surface of the housing body 120, the maximum length of the push-button switch sensing operation portion 530 is ensured, thus minimizing the wobbling of the push-button switch knob 510. That is, the tactile feedback of the push-button switch knob 510 can be improved.

[0101] On the other hand, regarding the location of the substrate, there are various options within the range of structures that minimize the number of substrates by mounting the first switch and the second switch on a single substrate. That is, the substrate 200 is located inside the housing 100 and can be configured adjacent to the exposed portion of the push-button switch section 500, such as... Figure 19 As shown, a structure can be adopted that is directly adjacent to the bottom surface of the housing cover 110. In this case, the push-button switch 500 can be designed as a simple capacitance switch, and the configuration of the composite switch 500 is the same as in the embodiments described above. In this case, multiple functions can be selected and combined, for example, the push-button switch 500 can be configured as a push-button switch capable of ultrasonic sensing to achieve fingerprint recognition, etc. That is, multiple methods can be selected, for example, the push-button switch 500 can be configured as an electronic switch and the composite switch 300 can provide a physical operating feel, or an additional tactile element can be added to the push-button switch 500 as an electronic switch to add a physical operating feel, etc.

[0102] This configuration further reduces the physical space, allowing for the adoption of a design that enables products to be made thinner.

[0103] The multi-function switch unit 10 described above can be configured as a vehicle with multiple selection switches, wherein the composite switch unit 300 is a gear selector switch for selecting the vehicle's gear, and the push-button switch unit 500 can be the vehicle's start switch, which is the same as described above.

[0104] And, as Figure 22As shown, the multi-functional switch unit 10 of this invention is mounted on the multi-functional switch module 1. In addition to the multi-functional switch unit 10, the multi-functional switch module 1 includes a storage unit 3 and a control unit 2. The storage unit 3 can store the initial state value sensed by at least one of the multiple switch units, as well as a preset value serving as a criterion for judging the operating state of at least one of the multiple switch units. Based on the initial state value stored in the storage unit 3, the control unit 2 uses the actual sensed state value sensed by at least one of the multiple switch units or the preset value to apply a calculation control signal to the calculation unit 4, thereby deriving an appropriate correction value for calibration as a zero-point adjustment of the sensing sensor.

[0105] Therefore, the multi-function switch unit 10 and the multi-function switch module 1 can be marketed with preset values ​​reflecting calibration items, etc., which reflect the initial sensing state. Furthermore, various options are available during use; for example, a structure can be adopted in which, at certain predetermined time points and at time points where conditions are met, the system autonomously diagnoses and senses the initial value to correct the sensing value.

[0106] The above description is merely an illustrative representation of the technical concept of this utility model. Those skilled in the art to which this utility model pertains can make various modifications and variations without departing from the essential characteristics of this utility model. Therefore, the disclosed embodiments in this utility model are used to illustrate the technical concept of this utility model and are not intended to limit the technical concept of this utility model. The scope of protection of this utility model should be interpreted based on the claims, and it should be interpreted that all technical concepts within the equivalent scope are included within the scope of protection of this utility model.
