Description

Vehicle multi-switch

[0001] The present invention relates to a multi-switch for vehicles.

[0002] Generally, a console box is placed between the driver's seat and the passenger seat in a vehicle.

[0003] These console boxes are divided into a rear console box, which can be used as an armrest for the driver and can store simple items using the space underneath, and a front console box, which accommodates various convenience functions such as a gear shift lever, side brake, cigarette lighter, and multi-switch.

[0004] In recent vehicles, the gear shift lever, which is housed in the front console box, is replaced by a lever switch on the steering wheel, and the handbrake is replaced by a pedal located at the driver's left foot. Therefore, the gear shift lever and handbrake are disappearing from the front console box.

[0005] This front console box is equipped with a convenience function control system for the driver.

[0006] The convenience function control system provided in the front console box includes a vehicle air conditioning control system, a vehicle audio control system, a driver and passenger seat heater control system, a driver and passenger seat seat control system, an interior lighting control system, etc.

[0007] Generally, the above convenience function control system is provided in the front console box as a type of switch that controls each convenience function.

[0008] The above front console box may have control functions for the gear shift lever and side brake added as a switch type.

[0009] However, as technology advances and the number of convenience function control systems included in the front console box increases, a separate switch is added for each function, leading to a problem where the space in the front console box becomes insufficient.

[0010] As a solution to the above problem, the convenience function control system is provided with a multi-switch that controls at least one convenience function.

[0011] However, in the case of conventional multi-switches, functions are divided through rotation like a wheel switch, which has the advantage of accommodating a wider variety of convenience function control inputs in the same space compared to a standard switch; yet, a problem arises in that the amount of input operations that can be implemented solely through rotation or pushing is limited.

[0012] In addition, conventional multi-switches have the problem of being visually exposed even when not in use, which detracts from the aesthetic appeal of the vehicle's interior space.

[0013]

[0014] The present invention aims to solve the aforementioned problems and other problems.

[0015] Another objective of the present invention may be to provide a vehicle multi-switch capable of accommodating user input in various ways, thereby enabling more convenience function control inputs relative to space.

[0016] Another objective of the present invention may be to provide a multi-switch for vehicles that can improve aesthetics by ensuring that the input part is not exposed to the outside when not in use by the user.

[0017] The problems of the present invention are not limited to those mentioned above, and other unmentioned problems will be clearly understood by those skilled in the art from the description below.

[0063] Hereinafter, the present invention will be described with reference to the drawings for explaining a vehicle multi-switch according to embodiments of the present invention.

[0064] FIG. 1 is a diagram showing a vehicle according to an embodiment of the present invention.

[0065] Referring to FIG. 1, a vehicle (A) according to an embodiment of the present invention has a console box (4) placed between the driver's seat (2) and the passenger seat (3). A vehicle multi-switch (1) according to an embodiment of the present invention is placed in the console box (4).

[0066] The vehicle multi-switch (1) can receive user input to control a convenience function control system for the driver.

[0067] FIG. 2 is a diagram showing a vehicle multi-switch according to an embodiment of the present invention.

[0068] Referring to FIG. 2, a vehicle multi-switch (1) according to an embodiment of the present invention includes a housing (10), a first printed circuit board (20), a cover (30), a rotation module (40), and an input unit (50).

[0069] The housing (10) receives power from the vehicle and supplies power to other components of the vehicle multi-switch through the first printed circuit board (20). The housing (10) forms a space on the inside and has an open top surface. The first printed circuit board (20) is accommodated in the inner space of the housing (10). A cover (30) is placed over the open top surface of the housing (10).

[0070] The first printed circuit board (20) supplies power from the vehicle supplied from the housing (10) to other components of the vehicle multi-switch. A rotation module (40) is installed on the first printed circuit board (20). The first printed circuit board (20) transmits user input received through the input section (50) to the vehicle. The vehicle, having received user input from the first printed circuit board (20), controls various vehicle convenience function provision systems.

[0071] The cover (30) is placed over the open upper surface of the housing (10). The cover (30) closes the open upper surface of the housing (10). The cover (30) may be provided with a plurality of push-type switches (31) on one side of the upper surface. The central portion of the cover (30) is recessed into the internal space of the housing (10). The cover (30) is installed so that the input portion (50) can rotate in the recessed portion of the central portion. The recessed portion of the cover (30) may be recessed in a hemispherical shape so as not to get caught when the input portion (50) rotates. The cover (30) may be provided with a connector portion (not shown) that allows the input portion (50) and the first printed circuit board (20) to be electrically connected. The cover (30) may be provided with a connection hole (not shown) through which the input part (50) and the rotation module (40) can be physically connected.

[0072] The rotation module (40) is installed on the first printed circuit board (20). The rotation module (40) can be physically connected to the input section (50) by passing through the cover (30). The rotation module (40) can rotate the input section (50).

[0073] The input unit (50) converts the user's input into an electrical signal through three operations and transmits it to the first printed circuit board (20).

[0074] Below, three operations of the input unit (50) according to an embodiment of the present invention will be described.

[0075] FIG. 3 is a diagram showing one operation of an input unit according to an embodiment of the present invention.

[0076] Referring to FIG. 3, one operation of the input unit (50) according to an embodiment of the present invention is that the input unit (50) rotates in one direction with respect to the cover (30) within a certain angle range.

[0077] For example, the input unit (50) can rotate in the forward direction within a range of 0 to 180 degrees relative to the cover (30). For example, the input unit (50) can rotate in the rear direction within a range of 0 to 180 degrees relative to the cover (30). For example, the input unit (50) can rotate in the left direction within a range of 0 to 180 degrees relative to the cover (30). For example, the input unit (50) can rotate in the right direction within a range of 0 to 180 degrees relative to the cover (30).

[0078] When the input section (50) rotates to a maximum of 180 degrees through a single operation, the input section (50) is received in the retracted portion of the cover (30). A decorative section (not shown) may be formed on the lower portion of the input section (50). When the input section (50) rotates to a maximum of 180 degrees through a single operation, the decorative section (not shown), which is the lower portion of the input section (50), may be exposed to the outside. The decorative section (not shown) may include a light source. When the decorative section (not shown) is exposed to the outside, light may be irradiated to the outside through the included light source. When the input section (50) returns to its original position of 0 degrees, the decorative section (not shown) is received in the retracted portion of the cover (30).

[0079] One operation of the input unit (50) can be operated by user input (external force of the user). For example, the user can operate the input unit (50) through external force to operate the deco unit (not shown).

[0080] The rotation of the input unit (50) may be an operation implemented by the rotation module (40) operating electrically in response to user input (a two-step or three-step operation of the input unit (50) described later). For example, the user may input a two-step operation to the input unit (50) to control the input unit (50) to operate one step. For example, the user may input a three-step operation to the input unit (50) to control the input unit (50) to operate one step.

[0081] FIG. 4 is a diagram showing a rotation module according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view showing a configuration implementing a single operation in an input unit according to an embodiment of the present invention.

[0082] Referring to FIGS. 4 and 5, the rotation module (40) includes a support member (41), a motor (42), a worm gear (43), a worm wheel gear (44), and a helical gear (45). The rotation module (40) is installed on the first printed circuit board (20). The rotation module (40) may be installed at a position corresponding to the rotation direction for the operation of the input member (50).

[0083] The support member (41) is installed on the first printed circuit board (20). A motor (42) is fixed to the support member (41).

[0084] The motor (42) may be selected as a step motor capable of precisely controlling rotation. The motor (42) is fixed to the upper side of the support member (41). The motor (42) generates rotational force. A worm gear (43) is installed on the rotation axis of the motor (42). The rotational force generated by the motor (42) is transmitted to the worm gear (43). The motor (42) can precisely control the rotation angle in 10-degree increments. If the motor (42) fails to perform rotation by the rotation angle controlled by an external force, it can provide feedback to the user.

[0085] The worm gear (43) is installed on the rotating shaft of the motor (42). The worm gear (43) is in contact with the worm wheel gear (44). The worm gear (43) transmits the rotational force received from the motor (42) to the worm wheel gear (44).

[0086] One side of the worm wheel gear (44) is in contact with the worm gear (43). The other side of the worm wheel gear (44) is in contact with the helical gear (45). The worm wheel gear (44) transmits the rotational force received from the worm gear (43) to the helical gear (45).

[0087] The helical gear (45) is fixed to one side of the input part (50). The helical gear (45) rotates the input part (50) through the rotational force received from the worm wheel gear (44).

[0088] The input section (50) includes a second housing (51).

[0089] The second housing (51) includes a case (511), a gear connection part (512), and a cover connection part (513).

[0090] The case (511) forms the outer shape of the second housing (51). A gear connection part (512) is formed on one side of the case (511). A cover connection part (513) is formed on the part of the case (511) opposite to the gear connection part (512).

[0091] The gear connection part (512) passes through the cover (30) and is connected to the rotation module (40). The gear connection part (512) passes through the cover (30) and is connected to the helical gear (45). The gear connection part (512) rotates together with the rotation of the helical gear (45). Depending on the rotation of the gear connection part (512), the input part (50) can rotate relative to the cover (30).

[0092] The cover connection part (513) is rotatably connected to the cover (30). When the gear connection part (512) rotates by receiving the rotational force of the rotation module (40), the cover connection part (513) is rotatably supported by the cover (30). Since the cover connection part (513) is supported by the cover (30), eccentricity can be prevented during operation of the input part (50).

[0093] FIG. 6 is a diagram showing the movement of an input unit according to an embodiment of the present invention, and FIG. 7 is a cross-sectional view showing a configuration implementing the movement of an input unit according to an embodiment of the present invention.

[0097] The second housing (51) forms a space inside, and the central portion of the upper surface is open. A third printed circuit board (56a) is accommodated in the internal space of the second housing (51). A rotary knob (53) is placed on the upper surface of the second housing (51). A friction-reducing member (54) is installed between the second housing (51) and the rotary knob (53). With respect to the fixed second housing (51), the rotary knob (53) can be rotated smoothly without friction by means of the friction-reducing member (54).

[0098] The knob holder (52) includes a penetration portion (521) and a support portion (522). The penetration portion (521) is a part that passes through the rotary knob (53) and is fixed by receiving the support force of the second housing (51). The support portion (522) is positioned below the bearing holder (532) of the rotary knob (53), which will be described later. The support portion (522) prevents the rotary knob (53) from moving downward. The knob holder (52) passes through the rotary knob (53) and is fixed to the third printed circuit board (56a). If the third printed circuit board (56a) is omitted, the knob holder (52) is fixed to the inner surface of the second housing (51). A friction reduction member (54) is installed between the outer surface of the knob holder (52) and the inner surface of the rotary knob (53). With respect to the fixed knob holder (52), the rotary knob (53) can be rotated smoothly without friction by means of the friction reduction member (54). The knob holder (52) penetrates through the friction reduction member (54) to allow the rotary knob (53) to rotate. A second printed circuit board (56b) is installed on the upper side of the knob holder (52). The knob holder (52) supports the push knob (58) through a push switch (562) provided on the second printed circuit board (56b).

[0099] The rotary knob (53) includes a grip holder (531), a bearing holder (532), and a grip portion (533). The grip holder (531) is positioned on the upper side of the second housing (51) and receives and fixes the grip portion (533) on its upper surface. The lower surface of the grip holder (531) may form a flat surface to allow the ball (5422) of the second friction-reducing member (542) to slide. The bearing holder (532) fixes the outer surface of the first friction-reducing member (541). A support portion (522) of the knob holder (52) is located on the lower side of the bearing holder (532) to prevent the bearing holder (532) from moving downward. The grip portion (533) is gripped by the user to rotate the rotary knob (53). The grip portion (533) is received and fixed in the grip holder (531).

The outer surface of the first friction reduction member (541) is fixed to the bearing holder (532) of the rotary knob (53). The outer surface and the inner surface of the first friction reduction member (541) are rotatably coupled. The second friction reduction member (542) includes a ball holder (5421) and a ball (5422). The ball holder (5421) is fixed to the upper surface of the second housing. A groove is formed on the upper surface of the ball holder (5421) to accommodate the upper portion of the ball (5422) so that it is exposed. The ball (5422) is rotatably received in the groove of the ball holder (5421). The upper portion of the ball (5422) contacts the lower surface of the grip holder (531) at the rotation knob (53). The ball (5422) reduces the frictional force caused by the rotation of the rotation knob (53).

[0101] The printed circuit board (56) includes a second printed circuit board (56b) and a third printed circuit board (56a). The printed circuit board (56) may be included in the first printed circuit board (20). The second printed circuit board (56b) includes a connector (561) and a push switch (562).

The first slider (592) includes a first slider plate (5921), a second center portion (5922), a pair of first guide projections (5923), and a pair of second guide projections (5924).

[0119] The first slider plate (5921) is positioned below the second holder (591). The first slider plate (5921) is formed in a plate shape. The central portion of the first slider plate (5921) is open to form a second central portion (5922). In a pair of opposing central portions among the upper, lower, left, and right ends of the first slider plate (5921), a first guide projection (5923a, 5923b) is formed protruding upward from the upper surface, respectively. In a pair of opposing central portions among the upper, lower, left, and right ends of the first slider plate (5921), excluding the portion where the first guide projection (5923a, 5923b) is formed, a second guide projection (5924a, 5924b) is formed protruding downward from the lower surface, respectively. The upper left, upper right, lower left, and lower right portions, which are located between the first guide projections (5923a, 5923b) and the second guide projections (5924a, 5924b) of the first slider plate (5921), are open so that the elastic member (5914) of the second holder (591) passes downward.

[0120] Referring to FIGS. 9, 10 and 13, the second slider (593) is located on the lower side of the sliding module (59). The second slider (593) is positioned on the lower side of the first slider (592). The second slider (593) includes a second slider plate (5931), a third center portion (5932), a second guide groove (5923), and a detent groove (5934).

[0121] The second slider plate (5931) is positioned below the first slider (592). The second slider plate (5931) is formed in a plate shape. The central portion of the second slider plate (5931) forms a third central portion (5922). Second guide grooves (5933a, 5933b, 5933c, 5933d) are formed at the central portions of the upper, lower, left, and right ends of the second slider plate (5931), respectively. In the upper left, upper right, lower left, and lower right portions, which are located between the second guide grooves (5933a, 5933b, 5933c, 5933d) of the second slider plate (5931), dent grooves (5934a, 5934b, 5934c, 5934d) are each formed protrudingly on the upper surface.

[0122] Hereinafter, the eight-directional sliding operation of the sliding module (59) implementing the three-way operation of the input unit (50) will be explained with reference to FIGS. 9 to 13.

[0123] Referring to FIGS. 9 through 13, a pair of opposing first guide grooves (5913a, 5913b, 5913c, 5913d) of the second holder (591) correspond to the first guide projections (5923a, 5923b) of the first slider (592). Accordingly, the second holder (591) and the first slider (592) slide along a single straight line.

[0124] For example, when a pair of opposing first guide grooves (5913a, 5913c) formed in the vertical direction among the first guide grooves (5913a, 5913b, 5913c, 5913d) of the second holder (591) correspond to the first guide projections (5923a, 5923b) of the first slider (592), the first slider (592) can slide vertically relative to the fixed second holder (591). For example, when a pair of opposing first guide grooves (5913b, 5913d) formed in the left-right direction among the first guide grooves (5913a, 5913b, 5913c, 5913d) of the second holder (591) correspond to the first guide projections (5923a, 5923b) of the first slider (592), the first slider (592) can slide in the left-right direction with respect to the fixed second holder (591).

[0125] The first guide groove (5913) of the second holder (591) is formed in two pairs facing each other, and since the first guide groove (5913) is formed in two pairs of point symmetry compared to the line symmetry where it is formed in one pair, the assembly directionality of the second holder (591) and the first slider (592) in the up, down, left, and right directions is reduced. In addition, since the assembly directionality of the second holder (591) and the first slider (592) is reduced, assembly becomes simpler and the convenience of assembly is increased.

[0126] The first slider (592) includes a pair of first guide protrusions (5923a, 5923b) that protrude upward and correspond to the second holder (591), and a pair of second guide protrusions (5924a, 5924b) that protrude downward and correspond to the second slider (593). Since the first guide protrusions (5923a, 5923b) and the second guide protrusions (5924a, 5924b) of the first slider (592) form symmetry, the assembly directionality of the second holder (591) and the first slider (592) is reduced. Additionally, the assembly directionality of the second holder (591) and the first slider (592) is reduced, making assembly easier and increasing the convenience of assembly.

[0127] A pair of opposing second guide grooves (5933a, 5933b, 5933c, 5933d) of the second slider (593) correspond to the second guide projections (5924a, 5924b) of the first slider (592). Accordingly, the second slider (593) and the first slider (592) slide along a single straight line.

[0128] For example, when a pair of opposing second guide grooves (5933a, 5933c) formed in the vertical direction among the second guide grooves (5933a, 5933b, 5933c, 5933d) of the second slider (593) correspond to the second guide projections (5924a, 5924b) of the first slider (592), the second slider (593) can slide vertically relative to the first slider (592). For example, when a pair of opposing second guide grooves (5933b, 5933d) formed in the left-right direction among the second guide grooves (5933a, 5933b, 5933c, 5933d) of the second slider (593) correspond to the second guide projections (5924a, 5924b) of the first slider (592), the second slider (593) can slide in the left-right direction relative to the first slider (592).

[0129] The second guide groove (5933) of the second slider (593) is formed in two pairs facing each other, and since the second guide groove (5933) is formed in two pairs of point symmetry compared to the line symmetry where it is formed in one pair, the assembly directionality of the second slider (593) and the first slider (592) in the up, down, left, and right directions is reduced. In addition, since the assembly directionality of the second slider (593) and the first slider (592) is reduced, assembly becomes simpler and the convenience of assembly is increased.

[0130] In summary, the first slider (592) slides in two directions along a single straight line relative to the fixed second holder (591). The second slider (593) slides in two directions relative to the first slider (592) along a straight line perpendicular to the single straight line. Thus, sliding motion in four directions—up, down, left, and right—is implemented.

[0131] In addition, the sliding of the first slider (592) with respect to the second holder (591) and the sliding of the second slider (593) with respect to the first slider (592) are applied simultaneously, so that sliding movements in four directions—upward, upward, downward, and downward—can be implemented.

[0132] The knob holder (52) passes through the first center portion (5912) and the second center portion (5922) and is connected to the third center portion (5932). The user can input three operations of the input portion (50) by sliding the knob holder (52), which is connected via the sliding module (59), in eight directions relative to the fixed second housing.

[0133] Referring to FIG. 13, the third central portion (5932) includes a stopper projection (5932a) that prevents rotation of the knob holder (52), a connector opening (5932b) through which a connector passing through the knob holder (52) penetrates into a printed circuit board on the lower side, and a screw hole (5932c) that prevents the knob holder (52) and the second slider (593) from coming apart.

[0134] Hereinafter, with reference to FIGS. 11 to 13, a structure that forms a sense of operation during the eight-directional sliding operation of the sliding module (59) will be explained.

[0135] Referring to FIG. 11, an elastic member (5914) is formed protruding downward from the second holder (591). The elastic member (5914) is formed in each space between the first guide grooves (5914) so ​​that eccentricity can be prevented during the eight-way sliding of the sliding module (59). The elastic member (5914) includes a support member (59142) and an elastic part (59141) that moves up and down relative to the support member (59142) and provides elastic force.

[0136] Referring to FIG. 12, the first slider (592) has an opening corresponding to the elastic member (5914) so ​​that the elastic member (5914) can come into contact with the second slider (593).

[0137] Referring to FIG. 13, a detent groove (5934) is formed in the second slider (593) in a portion corresponding to the elastic member (5914). In the detent groove (5934), a origin groove (59341) is formed in the central portion, and sliding grooves (59342) are formed in eight directions corresponding to the eight-direction sliding of the sliding module (59) centered on the origin groove (59341).

[0138] The origin groove (59341) is formed deeper than the eight sliding grooves (59342), so that the operation sensation in eight directions and the origin at the center can be differentiated.

[0139] The sliding grooves (59342) can be formed radially on the outer side of the origin groove (59341) at equal angles apart from each other. Each sliding groove (59342) is formed with the same depth. Each sliding groove (59342) has a step formed at the contact area with each other, so that a tactile sensation can be achieved even in a sliding motion in an adjacent direction without passing through the origin groove (59341) from one direction.
