Switches and door handles

Abstract

To satisfactorily illuminate a switch knob.SOLUTION: In a switch device 20, a switch part 44 and an LED 46 are accommodated in a housing 30. The housing 30 includes: a base plate 32 turnably connected with a door knob 10; a switch knob 34 that covers the switch part 44 and the LED 46 together with the base plate 32; and a switch cover 36 provided on the base plate 32. The switch knob 34 is exposed from an exposure hole 10C of the door knob 10 so as to be operable, and has a translucent part 34B that passes light of the LED 46. Accordingly, even if foreign matters such as water and dust enter inside the door knob 10 from the exposure hole 10C, the foreign matters can be suppressed from entering into the housing 30. As a result, a reduction in illuminance and brightness of the translucent part 34B can be suppressed. Thus, the switch knob 34 (translucent part 34B) can be satisfactorily illuminated.SELECTED DRAWING: Figure 5

DETAILED DESCRIPTION OF THE INVENTION

[0009] A door handle 10 to which a switch device 20 according to this embodiment is applied will be described below with reference to the drawings. As shown in FIG. 1, the door handle 10 is provided on a side door 60, which serves as a vehicle door of a vehicle (automobile) V, and the side door 60 is disposed on both sides of the vehicle V in the vehicle width direction. The front end of the side door 60 is rotatably connected to the body of the vehicle V by a hinge mechanism (not shown), with the vertical direction as the axial direction. Note that arrows UP, FR, and OUT, appropriately shown in the drawings, indicate the upper side, front side, and outer side of the vehicle V in the vehicle width direction, respectively, and the vehicle width direction coincides with the thickness direction of the side door 60. In the following description, when the up, down, and front-rear directions are used, they refer to the up, down, and front-rear directions of the vehicle unless otherwise specified. Below, the door handle 10 will be described first, and then the switch device 20 will be described.

[0010] (About Doorknob 10) As shown in Figures 2 to 6, the door knob 10 has a knob body 10A. The knob body 10A is formed as a hollow, generally elongated and flat body with its thickness in the up-down direction and its length in the front-to-rear direction. The inner end of the knob body 10A in the vehicle width direction is open toward the inside in the vehicle width direction and is fixed to the side door 60, with the knob body 10A protruding from the side door 60 toward the outside in the vehicle width direction. The door knob 10 is divided into two parts, upper and lower, by a knob base 12 that forms the lower part of the door knob 10 (knob body 10A) and an upper knob 14 that forms the upper part of the door knob 10 (knob body 10A), and the door knob 10 (knob body 10A) is formed by assembling the knob base 12 and the upper knob 14 together.

[0011] The side wall 12A on the outer side in the vehicle width direction of the knob base 12 is inclined outward in the vehicle width direction as it extends upward. A notch that opens outward in the vehicle width direction is formed in the rear portion of the side wall 12A, and the notch is formed along the bottom wall of the knob base 12. That is, an exposure hole 10C that opens outward and downward in the vehicle width direction is formed in the lower portion of the outer end of the rear portion of the knob body 10A in the vehicle width direction, and the exposure hole 10C exposes a switch knob 34 of a switch device 20 (described later) to the outside of the door handle 10.

[0012] The knob body 10A has a knob portion 10B formed at the outer end in the vehicle width direction, excluding the front end, that protrudes upward, and the knob portion 10B is configured as a grip portion to be gripped by an occupant. Specifically, when opening the side door 60, the occupant hooks their finger on the knob portion 10B from the inside in the vehicle width direction and pulls the knob portion 10B outward in the vehicle width direction.

[0013] A pair of front and rear support portions 10D (see FIG. 4) for supporting a switch device 20 (described later) are provided inside the upper knob 14 (only the rear support portion 10D is shown in FIG. 4). The support portion 10D is formed like a rib extending in the up-down direction with its thickness in the front-to-rear direction, and protrudes inward in the vehicle width direction from the vehicle width direction outer wall of both front-to-rear direction ends of the knob portion 10B. A support hole 10E is formed through the lower end of the support portion 10D. When viewed from the front-to-rear direction, one side around the center line of the support hole 10E (the side indicated by arrow A in FIG. 4) is one side in the movement direction of the switch device 20 (described later), and the other side around the center line of the support hole 10E (the side indicated by arrow B in FIG. 4) is the other side in the movement direction of the switch device 20 (described later).

[0014] The upper knob 14 is provided with a plurality of switch actuation portions 10F (see FIGS. 5 and 6 in this embodiment) for actuating switch portions 44 of the switch device 20 (described later). Each switch actuation portion 10F is formed as a rib extending vertically and having a thickness in the longitudinal direction. The switch actuation portions 10F protrude outward in the vehicle width direction from the inner wall of the knob portion 10B in the vehicle width direction. The three switch actuation portions 10F are arranged at predetermined intervals in the longitudinal direction between the pair of front and rear support portions 10D. The lower ends of the switch actuation portions 10F protrude downward from the upper wall of the upper knob 14. The lower end surfaces of the switch actuation portions 10F are configured as pressing surfaces 10G, which are inclined upward as they extend outward in the vehicle width direction when viewed from the longitudinal direction. In the following description, the direction along the pressing surfaces 10G when viewed from the longitudinal direction is referred to as the inclination direction, and the direction perpendicular to the inclination direction is referred to as the perpendicular direction. 4 is defined as one side of the orthogonal direction, and the arrow V2 is defined as the other side of the orthogonal direction.

[0015] A pair of front and rear stopper portions 10H (see FIG. 4) are formed inside the upper knob 14, and the stopper portions 10H are configured similarly to the switch actuation portions 10F. That is, the stopper portions 10H are formed as ribs extending vertically with a thickness in the longitudinal direction, and protrude outward in the vehicle width direction from the inner wall of the knob portion 10B in the vehicle width direction. The lower end of the stopper portion 10H protrudes downward beyond the upper wall of the upper knob 14. The lower end surface of the stopper portion 10H is configured as a stopper surface 10J, which is disposed along the inclined direction as viewed from the longitudinal direction and is slightly offset toward the other orthogonal direction side (the other side in the movement direction) from the pressing surface 10G of the switch actuation portion 10F. The stopper portions 10H are located outward in the longitudinal direction of the three switch actuation portions 10F (see FIG. 5).

[0016] (Regarding the switch device 20) The switch device 20 is housed within the doorknob 10 and is disposed below the knob portion 10B, with a portion of the switch device 20 exposed and operable through the exposure hole 10C. The switch device 20 includes a housing 30 that forms the outer shell of the switch device 20, and a board unit 40 and a light guide 50 (which, in a broad sense, are elements that can be understood as a light guide portion) housed within the housing 30.

[0017] (Regarding housing 30) The housing 30 is formed as a hollow, generally rectangular pillar extending in the front-to-rear direction. The housing 30 includes a base plate 32 serving as a housing base, a switch knob 34, and a switch cover 36. The base plate 32 constitutes one orthogonal end of the housing 30. The base plate 32 is formed as a generally elongated plate with the orthogonal direction as its thickness direction and the front-to-rear direction as its longitudinal direction, and is disposed on the other orthogonal side of the switch actuation portion 10F and the stopper portion 10H of the doorknob 10. A support shaft 32A extending in the front-to-rear direction is provided at the upper end of the base plate 32. Both front-to-rear direction ends of the support shaft 32A are inserted into support holes 10E of the support portion 10D of the doorknob 10 from the inside in the front-to-rear direction and are rotatably supported by the support portion 10D. This allows the switch device 20 to be rotatably connected to the doorknob 10 with the front-to-rear direction as its axial direction. Specifically, when the switch device 20 is in an inoperative state, the switch device 20 is located in an initial position (the position shown in Figures 4 and 6), and when pressed inward in the vehicle width direction, it is configured to rotate (move) from the initial position to one side in the movement direction and be located in an operating position (not shown).

[0018] As shown in FIG. 5 , three switch holes 32B for accommodating switch units 44 (described later) are formed through the base plate 32. The switch holes 32B are formed in a generally rectangular shape and are located at positions corresponding to the switch actuation units 10F of the doorknob 10. A connector hole 32C for accommodating a connector (described later) is formed through the base plate 32 between the front switch hole 32B and the switch hole 32B in the middle portion of the front-rear direction, and the connector hole 32C is formed in a generally rectangular shape with the longitudinal direction as the front-rear direction. A circular air hole 32D is formed through the base plate 32 between the rear switch hole 32B and the switch hole 32B in the middle portion of the front-rear direction. The air hole 32D is closed by a sheet 38 attached to one side surface (one side surface in the orthogonal direction) of the base plate 32. The sheet 38 is configured as a waterproof and breathable sheet.

[0019] 3 to 6, the switch knob 34 is formed in a generally elongated concave shape that extends in the front-rear direction and is open to one side in the orthogonal direction. A knob flange 34A is formed on the outer periphery of the opening of the switch knob 34, and the knob flange 34A is formed around the entire circumferential direction of the switch knob 34. The switch knob 34 is disposed adjacent to the other orthogonal side of the base plate 32, and the switch knob 34 is fixed to the base plate 32 so that the knob flange 34A is in close contact with the outer periphery of the base plate 32. In other words, the switch knob 34 is fixed to the base plate 32 so as to be movable integrally with the base plate 32, ensuring airtightness within the housing 30. The switch knob 34 is operably exposed through the exposure hole 10C of the door handle 10, and is configured as an input portion of the switch device 20 to which an operating force from an occupant is input. Specifically, the outer surface of the exposed surface of the switch knob 34 in the vehicle width direction is arranged flush with the outer peripheral surface of the side wall 12A of the knob base 12, and the lower surface of the exposed surface of the switch knob 34 is arranged flush with the lower surface of the knob base 12. The switch knob 34 is made of a material that can transmit light, and the part of the switch knob 34 that is exposed to the outside of the door knob 10 through the exposure hole 10C is configured as the light-transmitting part 34B.

[0020] As shown in FIGS. 5 and 6 , the switch covers 36 are provided on the base plate 32 in correspondence with the switch holes 32B. That is, in this embodiment, three switch covers 36 are provided on the base plate 32. The switch covers 36 are made of an elastic material (elastomer in this embodiment) and are formed in a relatively shallow rectangular recess that is open to the other side in the orthogonal direction. The openings of the switch covers 36 are formed integrally with the periphery of the switch holes 32B of the base plate 32 by a method such as two-color molding. As a result, the switch holes 32B are closed by the switch covers 36. A boss 36A is provided in approximately the center of the switch cover 36. The boss 36A is formed in a substantially cylindrical shape with its axial direction aligned with the orthogonal direction and protrudes from the switch cover 36 to the other side in the orthogonal direction.

[0021] The switch cover 36 is disposed at a position offset to one side in the orthogonal direction with respect to one side of the base plate 32, and is adjacent to the other side in the orthogonal direction of the pressing surface 10G of the switch actuation portion 10F. When the switch device 20 is rotated to the operating position, the switch cover 36 is pressed to the other side in the orthogonal direction by the switch actuation portion 10F and elastically deforms, and the boss 36A presses the switch portion 44, which will be described later. When the switch device 20 is in the operating position, the stopper surface 10J of the stopper portion 10H abuts against the base plate 32, and rotation of the switch device 20 to one side in the movement direction is limited by the stopper portion 10H.

[0022] (Regarding the board unit 40) The board unit 40 includes a board 42, three switch sections 44, and a pair of LEDs 46 as light sources. The board 42 is formed in a generally elongated plate shape with the orthogonal direction as the board thickness direction and the front-to-rear direction as the longitudinal direction. The board 42 is accommodated within the housing 30, and is disposed adjacent to the other side of the base plate 32 in the orthogonal direction and fixed to the base plate 32.

[0023] The switch section 44 is provided on one side (one side in the orthogonal direction) of the substrate 42, and is disposed within the switch hole 32B of the base plate 32. The switch section 44 is configured as a push switch such as a tactile switch, and is disposed adjacent to the other orthogonal side of the boss 36A of the switch cover 36. As a result, the switch section 44 is covered from one orthogonal side by the switch cover 36, and when the switch device 20 is rotated to the operating position, the switch cover 36 pressed by the switch actuation section 10F presses the switch section 44, turning it on.

[0024] The LEDs 46 are provided on the other side surface (the other side surface in the perpendicular direction) of the substrate 42 and are arranged at both front and rear end portions of the substrate 42. The LEDs 46 irradiate emitted light toward the other side in the perpendicular direction to illuminate the light-transmitting portion 34B of the switch knob 34.

[0025] A control unit 62 serving as a detection unit of the vehicle V is connected to the board 42, and the switch unit 44 and the LED 46 are electrically connected to the control unit 62. More specifically, a connector (not shown) provided at one end of a harness extending from the control unit 62 is disposed in the connector hole 32C and connected to the board 42. Whether the switch knob 34 has been operated to an operating position is detected based on an output signal from the switch unit 44, and the LED 46 is illuminated under the control of the control unit 62. More specifically, the control unit 62 detects that the switch device 20 has been operated when it detects that the output signal of at least one switch unit 44 has been switched from OFF to ON.

[0026] (About Light Guide 50) The light guide 50 is formed in a generally elongated plate shape with the orthogonal direction as its thickness direction and the front-rear direction as its longitudinal direction. The light guide 50 is accommodated in the housing 30, disposed adjacent to the other orthogonal side of the substrate 42, and fixed to the substrate 42. Recesses 50A are formed at both front-rear end portions of the light guide 50, protruding toward the other orthogonal side and opening toward one orthogonal side, and the LEDs 46 are disposed within the recesses 50A. The light guide 50 is made of a light-transmitting resin material or the like and is configured as a so-called lens. As a result, light emitted by the LEDs 46 is guided toward the center of the light guide 50 in the front-rear direction, illuminating the entire light-transmitting portion 34B of the switch knob 34 in the front-rear direction.

[0027] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0028] When the switch device 20 of the door handle 10 configured as described above is in an inoperative state, the switch device 20 is located in an initial position. When an occupant operates the switch device 20 to open the side door 60, the occupant places the fingers other than the thumb on the inner side of the knob portion 10B of the door handle 10 in the vehicle width direction so that the fingers are hooked on the knob portion 10B, and places the thumb on the outer side of the switch knob 34 in the vehicle width direction to grasp the door handle 10.

[0029] In this state, when the occupant presses the switch knob 34 inward in the vehicle width direction, the entire switch device 20 rotates from the initial position to one side in the movement direction and is placed in the operating position. When the switch device 20 is in the operating position, the switch actuation portion 10F of the door handle 10 presses the switch cover 36 of the switch device 20 to the other side in the perpendicular direction, causing the switch cover 36 to elastically deform. This causes the boss 36A of the switch cover 36 to press the switch portion 44. Therefore, an ON signal is output from the switch portion 44 to the control unit 62, and the control unit 62 detects the operation of the switch device 20. When the control unit 62 detects the operation of the switch device 20, the control unit 62 unlocks the locking device of the side door 60, allowing the side door 60 to be opened or closed. In this state, when the occupant pulls the knob portion 10B outward in the vehicle width direction, the side door 60 is opened.

[0030] Here, in the switch device 20, the switch unit 44 and the LED 46 are housed in a housing 30 that forms the outer shell of the switch device 20. The housing 30 includes a base plate 32 rotatably connected to the doorknob 10, a switch knob 34 that is immovably connected to the base plate 32 and that, together with the base plate 32, covers the switch unit 44 and the LED 46, and a switch cover 36 that is provided on the base plate 32. The switch knob 34 is operably exposed through the exposure hole 10C of the doorknob 10 and has a light-transmitting portion 34B that transmits light from the LED 46. As described above, when the switch device 20 is actuated, the entire housing 30 (the entire switch device 20) that houses the switch unit 44 and the LED 46 rotates from the initial position to the operating position. Therefore, even if foreign matter such as water or dust enters the doorknob 10 through the exposure hole 10C, the intrusion of the foreign matter into the housing 30 (the switch device 20) can be prevented. That is, by configuring the housing 30 that houses the switch portion 44 and the LED 46 to move as a whole, it is possible to prevent foreign matter from entering the light transmission path from the LED 46 to the light-transmitting portion 34B. As a result, it is possible to prevent a decrease in the illuminance and brightness of the light-transmitting portion 34B. Therefore, it is possible to effectively illuminate the switch knob 34 (light-transmitting portion 34B).

[0031] Furthermore, the switch cover 36 is made of an elastic material, and when the switch device 20 is in the operating position, the switch cover 36 is pressed by the switch actuation portion 10F of the doorknob 10 and elastically deforms to the other side in the orthogonal direction, pressing the switch portion 44. Therefore, even if the entire switch device 20 is configured to move, the switch portion 44 can be pressed and actuated when in the operating position.

[0032] Furthermore, in the board unit 40 accommodated in the housing 30, the switch section 44 is provided on one side of the board 42, and the LED 46 is provided on the other side of the board 42. This allows the switch section 44 and the LED 46 to be provided on the board 42, utilizing both sides of the board 42. Furthermore, the base plate 32 is formed with a switch hole 32B for arranging the switch section 44, and the switch cover 36 covers the switch section 44 from one side in the movement direction while closing the switch hole 32B. This allows the board 42 to be arranged adjacent to the other side of the base plate 32 in the perpendicular direction, and the switch section 44 can be pressed by the switch cover 36 provided on the base plate 32. This therefore contributes to the miniaturization of the switch device 20, while ensuring airtightness within the housing 30.

[0033] Furthermore, in the substrate unit 40, a plurality of switch sections 44 (three in this embodiment) are provided on the substrate 42, and the control section 62 detects an operation on the switch device 20 based on an ON signal from any of the switch sections 44. Therefore, even if any of the switch sections 44 is damaged, the operation on the switch device 20 can be detected based on the output signals of the remaining switch sections 44. This improves the reliability of the switch device 20.

[0034] Furthermore, the base plate 32 is rotatably supported by the doorknob 10, and the housing 30 is rotatably connected to the doorknob 10 with the front-to-rear direction as its axial direction. This allows the switch device 20 to be smoothly operated and the switch unit 44 to be actuated. That is, for example, if the base plate 32 (housing 30) is slidably connected to the doorknob 10 in the front-to-rear direction, the switch unit 44 may not be smoothly actuated due to inclination of the base plate 32, etc. In particular, with a switch device 20 that extends in the front-to-rear direction, it may be difficult to smoothly actuate the switch unit 44 due to inclination of the switch device 20 relative to the doorknob 10. In contrast, in this embodiment, the base plate 32 is rotatably supported by the doorknob 10, and the housing 30 is rotatably connected to the doorknob 10. This allows the switch device 20 to be smoothly operated and the switch unit 44 to be actuated, compared to when the base plate 32 (housing 30) is slidably connected to the doorknob 10 in the front-to-rear direction. Furthermore, in the switch device 20 of this embodiment, the base plate 32 tilts less when operated compared to when the base plate 32 is connected to the doorknob 10 so that it can slide back and forth, and even when multiple switch units 44 are provided on the substrate 42, all switch units 44 can be reliably activated simultaneously, thereby further improving reliability.

[0035] The door handle 10 includes a knob body 10A fixed to the side door 60 and a knob portion 10B protruding upward from the knob body 10A. The switch device 20 is housed within the knob body 10A, and the switch knob 34 of the switch device 20 is exposed outward in the vehicle width direction through an exposure hole 10C in the knob body 10A. Therefore, as described above, the occupant can apply an operating force to the switch device 20 by pressing the switch knob 34 inward in the vehicle width direction with their thumb while hooking their fingers other than their thumb on the knob portion 10B. This allows a relatively high operating force to be applied to the switch device 20. After operating the switch device 20, the occupant can open the side door 60 by pulling the knob portion 10B with their fingers other than their thumb. As described above, the door handle 10 can be made easier for the occupant to operate.

[0036] Furthermore, the knob portion 10B protrudes upward from the outer end of the knob body 10A in the vehicle width direction, and the switch device 20 is disposed below the knob portion 10B and is exposed downward and outward in the vehicle width direction from the knob body 10A. This ensures operability of the switch device 20 while preventing foreign objects from entering the door handle 10 through the exposure hole 10C. Even if a foreign object does enter the door handle 10, the exposure hole 10C is open downward, so the foreign object can be easily expelled downward from the exposure hole 10C.

[0037] In this embodiment, an example has been shown in which the switch device 20 is applied to the door handle 10 of the side door 60, but for example, the switch device 20 may also be applied to the door handle of a back door at the rear end of the vehicle V. The switch device 20 may also be configured to be directly provided on the side door 60, the back door, etc. In this case, the switch device 20 is movably connected to the side door 60 and the back door, and is exposed through exposure holes formed in the side door 60 and the back door.
