Description

switch device

[0001] The present invention relates to a switch device. In particular, the present invention relates to a switch device with reduced sensing error through component minimization.

[0002] Lever-type switch devices generally have a sensing structure using various parts.

[0003] Meanwhile, existing switch devices have a problem in that the sensor detection error range is large due to the accumulated tolerance caused by various parts.

[0004] Accordingly, a practical need arises to minimize the cumulative tolerance between parts by using only the essential parts required for the operation of the switch device.

[0088] The pin move assembly (300) may include an elastic body (330). The elastic body (330) may be coupled to the pin move (310). At least a portion of the elastic body (330) may be accommodated in the pin move (310). A portion of the elastic body (330) coupled to the pin move (310) may be exposed to the outside of the pin move (310).

[0089] For example, the elastic body (330) may enter through the upper portion of the pin move (310) and be coupled to the pin move hollow portion (313). The elastic body (330) may be formed in a shape in which a lower portion is received in the pin move hollow portion (313) and an upper portion is exposed to the outside of the pin move (310).

[0090] An elastic body (330) may be placed between the pin move (310) and the operating lever (200). The elastic body (330) may elastically couple the pin move (310) and the operating lever (200). For example, one end of the elastic body (330) may be coupled to the pin move (310), and the other end of the elastic body (330) may be coupled to the operating lever (200).

[0091] When the operating lever (200) moves, the pin move (310) can move while contacting the cam block (400). When the pin move (310) moves while contacting the cam block (400), the distance between the two ends of the elastic body (330) can change.

[0092] For example, when the operating lever (200) moves, the pin move (310) can move while contacting the upper surface of the cam block (400). The elastic force formed in the pin move (301) by the elastic body (330) can be directed toward the upper surface of the cam block (400). The elastic force formed in the pin move (301) can vary depending on the position of the pin move (310).

[0093] For example, when the operating lever (200) moves, the pin move (310) may move inwardly of the lever body (210). As the lever body (210) moves inwardly, the distance between the two ends of the elastic body (330) may decrease. As the distance between the two ends of the elastic body (330) decreases, the elastic body (330) may receive pressure applied between the two ends of the elastic body (330).

[0094] For example, when the operating lever (200) moves, the pin move (310) can move outwardly of the lever body (210). The outward movement of the lever body (210) can be possible through elastic force generated according to pressure applied between both ends of the elastic body (330).

[0095] Referring to FIG. 3, the cam block (400) may include a cam block body (410). The cam block body (410) may be coupled to the housing body (110).

For example, the upper surface of the cam block body (410) may mean the upper surface of the cam block (400).

[0096] The cam block body (410) may be formed so that at least a portion of the upper surface is curved. For example, the upper surface of the cam block body (410) may be formed so as to be concave downward. Meanwhile, for example, the upper surface of the cam block body (410) may be formed so as to be convex upward. For example, the upper surface of the cam block body (410) may be formed so that a concave shape and a convex shape are connected.

[0097] The cam block body (410) may include a cam block body bottom surface (410B). The cam block body bottom surface (410B) may form a lower surface of the cam block body (410).

The cam block body side surface (410S) may extend longitudinally from both sides of the cam block body bottom surface (410B). A pair of cam block body side surfaces (410S) may be formed symmetrically.

[0098] The cam block body (410) may include a cam block body wall (410T). The cam block body wall (410T) may extend from the cam block body side surface (410S). The cam block body wall (410T) may form at least a portion of an upper surface of the cam block body (410). The cam block body wall (410T) may be formed symmetrically on the upper surface of the cam block body (410).

For example, the cam block body slit (430) may be at least a portion of an upper face formed on the cam block body (410).

[0101] The cam block body cleavage portion (430) may be concave overall. For example, the cam block body cleavage portion (430) may accommodate a pin move assembly (300).

[0110] At least one of the left-side slope (431L) and the right-side slope (431R) may include multiple slopes.

[0111] For example, the left theft mountain slope (431L) may include a first left theft mountain slope (431L1), a second left theft mountain slope (431L2), and a third left theft mountain slope (431L3). A plurality of left theft mountain slopes (431L1, 431L2, 431L3) may be arranged sequentially.

[0115] For example, the right theft mountain slope (431R) may include a first right theft mountain slope (431R1), a second right theft mountain slope (431R2), and a third right theft mountain slope (431R3). A plurality of right theft mountain slopes (431R1, 431R2, 431R3) may be arranged sequentially.

[0119] The ridge recess (432) may be concave. The ridge recess (432) may be formed between two adjacent ridge slopes (431). For example, the ridge recess (432) may be formed by two adjacent ridge slopes (431).

[0120] For example, the left burr recess (432L) may include a first left burr recess (432L1) and a second left burr recess (432L2).

[0121] Multiple left-side sloping slopes (432L1, 432L2) may be arranged sequentially. For example, a first left-side sloping slope (431L1), a first left-side sloping slope (432L1), and a second left-side sloping slope (432L2) may be arranged sequentially.

[0122] For example, the first left saddle slope concave portion (432L1) may be connected to the first left saddle slope (431L1) and the second left saddle slope (431L2). For example, the first left saddle slope concave portion (432L1) may be located between the first left saddle slope (431L1) and the second left saddle slope (431L2).

[0127] For example, the first right-side saddle recess (432R1) may be connected to the first right-side saddle slope (431R1) and the second right-side saddle slope (431R2). For example, the first right-side saddle recess (432R1) may be located between the first right-side saddle slope (431R1) and the second right-side saddle slope (431R2).

[0130] The left cam block body spur (430L) may include a left spur slope (431L) and a left spur concave (432L). The left cam block body spur (430L) may have the left spur slope (431L) and the left spur concave (432L) alternately arranged.

[0131] For example, in the thief-mountain connecting portion (433), the left thief-mountain slope (431L) and the left thief-mountain concave portion (432L) may be arranged alternately. For example, from the thief-mountain connecting portion (433), the first left thief-mountain slope (431L1), the first left thief-mountain concave portion (432L1), the second left thief-mountain slope (431L2), the second left thief-mountain concave portion (432L2), and the third left thief-mountain slope (431L3) may be arranged in sequence.

[0132] The right cam block body spur (430R) may include a right spur slope (431R) and a right spur concave portion (432R). The right cam block body spur (430R) may have the right spur slope (431R) and the right spur concave portion (432R) alternately arranged.

[0133] For example, from the thief connection (433), the first right thief slope (431R1), the first right thief concave portion (432R1), the second right thief slope (431R2), the second right thief concave portion (432R2), and the third right thief slope (431R3) can be arranged in sequence.

[0134] The cam block body cleavage section (430) can enable the step-by-step engagement of the pin move (310). That is, the pin move tip (312) of the pin move (310) can generate a sense of operation and sound while passing through the cam block body cleavage section (430) formed in multiple stages.

[0135] The pin move tip (312) can be positioned along the cam block body spur (430). During the position change process, a pressure change according to the tangential slope may occur at the contact point between the cam block body spur (430) and the pin move tip (312). For example, when the pin move tip (312) is settled from the first left spur slope (431L1) or the second left spur slope (431L2) to the first left spur concave portion (432L1), a change in the operating feel may occur due to a pressure change according to the tangential slope.

[0136] The above pressure change may be caused by the elastic body (330) supporting the pin move (310). Depending on the pressure applied between the two ends of the elastic body (330) and the tangential slope at the saddle slope (431), the rotational torque of the operating lever (200) may change. Accordingly, a change in the user's operational feel detected through the operating lever (200) may occur.

[0137] Referring to FIGS. 3 to 5, the present invention can provide a multi-stage operating state through the cam block body cleavage section (430).

[0138] In the initial state of the switch device (10) (see the dotted line in FIG. 5 and FIG. 3), the pin move tip (312) of the pin move assembly (300) is seated in the truss rod connection portion (433). For example, in a state where no external force is applied to the operating lever (200), the pin move tip (312) may be positioned in the truss rod connection portion (433) corresponding to the lowest end of the cam block body truss rod portion (430). As described above, the initial state in which the pin move tip (312) is seated in the truss rod connection portion (433) may be referred to as the 'origin mode'.

[0139] When operating the operating lever (200), the pin move assembly (300) can move in a forward or reverse direction. The forward direction can be defined as rotation of the pin move assembly (300) toward the left cam block body spur (430L), and the reverse direction can be defined as rotation of the pin move assembly (300) toward the right cam block body spur (430R).

[0140] When the operating lever (200) rotates in the forward direction, a state in which the pin move tip (312) is positioned in the first left concave portion (432L1) of the swivel head can be referred to as a 'first forward mode'. When the operating lever (200) rotates in the forward direction, a state in which the pin move tip (312) is positioned in the second left concave portion (432L2) of the swivel head can be referred to as a 'second forward mode'.

[0141] Referring to FIG. 5, the pin move tip (312) is shown to be located on the second left spur slope (431L2), indicating a state of moving from the 'first forward mode' to the 'second forward mode'.

[0142] Meanwhile, when the operating lever (200) rotates in the reverse direction, the state in which the pin move tip (312) is positioned in the first right-hand slit concave portion (432R1) may be referred to as the 'first reverse mode'. When the operating lever (200) rotates in the reverse direction, the state in which the pin move tip (312) is positioned in the second right-hand slit concave portion (432R2) may be referred to as the 'second reverse mode'.

[0143] The switch device (10) of the present invention can be used to control the window speed of a vehicle. For example, the first forward mode and the second forward mode can be used to control the window's raising speed. For example, the first reverse mode and the second reverse mode can be used to control the window's lowering speed.

[0144] Referring to FIGS. 3 and 4, the substrate assembly (500) may include a substrate (510). The substrate (510) may be a flexible printed circuit board (FPCB). The substrate (510) may have a board or plate shape. The substrate (510) may be positioned on the bottom surface of the cam block body (410). The upper surface of the substrate (510) may face or face the lower surface of the cam block body (410). The lower surface of the substrate (510) may face downward.

[0145] The substrate assembly (500) may include a sensor (520). The sensor (520) may be coupled to the substrate (510). The sensor (520) may be disposed on the lower surface of the substrate (510). The sensor (520) may be positioned below the cam block body cleavage member (430). The sensor (520) may be positioned below the cleavage connection member (433).

[0146] The sensor (520) can detect the position of the pin move assembly (300) that changes position along the cam block body theft section (430). The sensor (520) can determine the position of the magnet (320) by using the magnetic relationship with the magnet (320) built into the pin move assembly (300).

[0147] The sensor (520) may be located below or on the side of the cam block (400). For example, the sensor (520) may be in close contact with the cam block body (410) with the substrate (510) therebetween. The sensor (520) may also be in direct contact with the cam block body (410).

[0148] Due to this close relationship, the sensor (520) can more accurately detect the position of the magnet (320). When the pin move (310) is elastically pressed against the upper surface of the cam block body (410) and the sensor (520) is pressed against the lower surface, the distance between the pin move (310) and the sensor (520) can converge to the upper and lower thickness of the cam block body (410).

[0149] That is, since there is no empty space between the pin move (310) and the sensor (520), the tolerance of the distance between the pin move (310) and the sensor (520) can be minimized. Accordingly, the tolerance of the distance between the magnet (320) and the sensor (520) is also minimized, so that the sensor (520) can accurately detect the position of the magnet (320).

[0150] In addition, since the magnetic body (320) is built into the pin move (310) that generates the operational feeling, a separate structure or space for mounting the magnetic body (320) may not be necessary. That is, since the sensing structure is integrated into the operational feeling generating structure, the switch device (10) can be made of a smaller and simpler structure.

[0151] The sensor (520) may be a Hall sensor. The sensor (520) can detect changes in the strength and direction of the magnetic flux that change according to changes in the position of the magnet (320). For example, when the position of the pin move assembly (300) in which the magnet (320) is built is changed, the sensor (520) can detect changes in the strength and direction of the magnetic flux that change according to changes in the positional relationship between the magnet (320) and the sensor (520). The sensor (520) may be a multi-axis Hall sensor that can detect magnetic fields in multiple directions simultaneously.

[0152] The magnetic body (320) can form a magnetic field. The magnetic body (320) can include, for example, a permanent magnet. As another example, the magnetic body (320) can include an electromagnet.

[0153] Depending on the operation of the operating lever (200), the pin move assembly (300) can rotate around the first rotation axis (AX1). Through this, the distance between the magnet (320) and the sensor (520) built into the pin move assembly (300) can be changed. The magnet (320) can provide magnetic flux to the cam block (400).

[0154] When the pin move tip (312) of the pin move assembly (300) changes position from the first left pin concave portion (432L1) to the first right pin concave portion (432R1) in the state where the magnetic body (320) forms a magnetic field, the size or intensity of the magnetic flux detected by the sensor (520) may change.

[0155] For example, when the pin move tip (312) changes from the first left pin move concave portion (432L1) to the first right pin move concave portion (432R1) in the spur connecting portion (433) while the magnet (320) forms a magnetic field, the size or intensity of the magnetic flux detected by the sensor (520) may decrease. For example, as the distance between the magnet (320) embedded in the pin move tip (312) and the sensor (520) increases, the size or intensity of the magnetic flux detected by the sensor (520) may decrease.

[0156] For example, when the magnetic body (320) includes an electromagnet, the power applied to the magnetic body (320) can be adjusted. For example, when the magnetic body (320) is an electromagnet and the current applied to the magnetic body (320) increases, the size or intensity of the magnetic flux detected by the sensor (520) can increase. For example, when the magnetic body (320) is an electromagnet and the current applied to the magnetic body (320) decreases, the size or intensity of the magnetic flux detected by the sensor (520) can decrease.

[0157] The magnetic body (320) may be formed of a material including metal. For example, the magnetic body (320) may be formed of a material including a ferromagnetic substance. For example, the magnetic body (320) may be formed of a material including iron. For example, the magnetic body (320) may be formed of a material including a paramagnetic substance.

[0158] Referring to FIG. 6, the magnetic body (320) may have a first magnetic pole (321) and a second magnetic pole (322) arranged parallel to the longitudinal direction of the pin move assembly (300). For example, the magnetic force lines may be formed symmetrically around an imaginary line passing through the central axis of the pin move assembly (300).

[0159] Referring to FIG. 7, the magnetic body (320) may have a first magnetic pole (321) and a second magnetic pole (322) arranged in parallel in the transverse direction of the pin move assembly (300). For example, the magnetic force lines may be formed symmetrically around an imaginary line parallel to the transverse direction of the pin move assembly (300).

[0160] Referring to FIG. 8, the number of magnetic bodies (320) may be plural. For example, the plurality of magnetic bodies (320) may be spaced apart from each other along the longitudinal direction of the pin move assembly (300). Meanwhile, the plurality of magnetic bodies (320) may be spaced apart from each other along the longitudinal direction of the pin move assembly (300). Meanwhile, the plurality of magnetic bodies (320) may be arranged in a grid shape along the transverse direction and the longitudinal direction of the pin move assembly (300).

[0161] Referring to FIG. 9, the substrate assembly (500) may include a plurality of sensors (520). The plurality of sensors (520) may be a pair. The pair of sensors (520) may be symmetrically arranged with respect to the skewer connection part (433). For example, the pair of sensors (520) may be symmetrically arranged on a cam block (400) that is formed symmetrically along the left-right direction. The pair of sensors (520) may include a first sensor (520L) and a second sensor (520R).

[0162] The sensor (520) may be coupled to the substrate (510). The sensor (520) may be placed on the lower surface of the substrate (510). The sensor (520) may be located below the cam block body cleavage section (430). The sensor (520) may be located below the cleavage connecting section (433).

[0163] When the pin move tip (312) of the pin move assembly (300) changes position from the spur connection (433) to the spur slope (431) while the magnetic body (320) forms a magnetic field, the size or intensity of the magnetic flux detected by the sensor (520) may change.

[0164] For example, when the pin move tip (312) is changed from the theft-mounted connecting portion (433) to the theft-mounted slope (431) placed on the first sensor (520L) side while the magnet (320) forms a magnetic field, the size or intensity of the magnetic flux detected by the first sensor (520L) may increase.

[0165] Meanwhile, when the pin move tip (312) is changed from the theft-mountain connecting portion (433) to the theft-mountain slope (431) placed on the first sensor (520L) side while the magnetic body (320) forms a magnetic field, the size or intensity of the magnetic flux detected by the second sensor (520R) may decrease.

[0166] Referring to FIGS. 1 to 9, the operating lever (200) is described as being rotatably coupled to the housing (100), but may not be limited thereto. For example, the operating lever (200) may be capable of translational or linear movement relative to the housing (100).
