As shown in
The emergency call operation element 32 of the present embodiment is a member molded in a form of a box called the knob. The emergency call operation element 32 is stored in the emergency call operation element storage part 40 that is one of the plurality of operation element storage parts 16 in the same manner as in the other switches 12. The emergency call operation element 32 is inserted into an opening 42 provided in a bottom surface 40A of the emergency call operation element storage part 40, and protrudes from the opening 42 with a height dimension smaller than a height dimension of a dent of the emergency call operation element storage part 40 to such an extent that the operation element does not protrude outward from the dent.
As shown in
The emergency call display 34 is provided in the operation surface 32A of the emergency call operation element 32. The emergency call display 34 is molded in a form of a symbol or a letter representing an emergency call in the same manner as in the other display 22, and is formed so that light from the light source 21 provided in a rear surface of the emergency call operation element 32 can be transmitted.
Since the operation surface 32A is provided toward the occupant as described above, the emergency call display 34 is similarly provided toward the occupant. Consequently, in a case where the occupant sees the emergency call display 34, distortion of the emergency call display 34 can be suppressed, and visual recognition can improve.
Here, the emergency call operation element storage part 40 is described in detail, and the emergency call operation element storage part 40 comprises the bottom surface 40A, a side surface 40B, and a continuous surface 40C.
The bottom surface 40A has a central part in which an opening 42 is provided.
The side surface 40B is vertically provided downward from the bottom surface 40A, and disposed facing each side surface of the emergency call operation element 32 to surround the emergency call operation element 32.
The continuous surface 40C couples the side surface 40B and the operation panel 10, and the continuous surface 40C is formed as a curved surface having a downwardly protruding shape in cross-sectional view in an up-down direction.
Furthermore, in the emergency call operation element storage part 40, as shown in
As shown in
A support 50 is inserted into each of the support insertion holes 44. Each support 50 is a member formed as a flat plate, and these supports 50 are vertically provided on the bottom surface 40A of the emergency call operation element storage part 40. Furthermore, the respective supports 50 have flexibility.
A protruding portion 52 is provided on the side surface of each of the supports 50 that faces the emergency call operation element 32.
Each protruding portion 52 protrudes in the vehicle width direction along a width to such an extent that the protruding portion does not come in contact with the emergency call operation element 32, and the protruding portion 52 has a lower end side including a tip inclined portion 54.
The tip inclined portion 54 is an inclined surface inclined at an upward gradient toward a tip of the protruding portion 52, and the tip inclined portion 54 forms a lower surface of the protruding portion 52 in the up-down direction. That is, the protruding portion 52 is formed so that a width dimension in the up-down direction decreases as being toward the tip.
Note that each protruding portion 52 is located behind the emergency call operation element 32 in side view in the vehicle width direction of the emergency call operation element 32.
The pair of engaging portions 46 are provided on the side surface 40B of the emergency call operation element storage part 40. Each of the engaging portions 46 has a protruding shape protruding toward each side surface of the emergency call operation element 32 that is located in the width direction of the vehicle along a width to such an extent that the engaging portion does not come in contact with the emergency call operation element 32.
Each engaging portion 46 is disposed at a position opposite to a front side of the side surface of the emergency call operation element 32 in the front-back direction of the vehicle.
The stopper 48 is provided on the bottom surface 40A of the emergency call operation element storage part 40, and the stopper 48 is disposed adjacent to the side surface of the emergency call operation element 32 that is located on the rear side of the vehicle. The stopper 48 has a protruding shape protruding downward along the side surface of the emergency call operation element 32 that is located on the rear side of the vehicle. The stopper 48 is formed to have a height to such an extent that a tip of the protruding shape does not protrude downward from the operation surface 32A of the emergency call operation element 32.
Consequently, the stopper 48 is hidden behind the rear surface of the emergency call operation element 32, and disposed so that the stopper is not visually recognized by the occupant.
The stopper 48 includes an abutment inclined portion 48A inclined at an upward gradient from a tip of the protruding shape toward the rear side of the vehicle. The abutment inclined portion 48A is an inclined surface formed as a flat surface, and the abutment inclined portion 48A forms a lower surface of the stopper 48 in the up-down direction.
The indicator communication hole 49 is a through hole that communicates with the indicator 14, and the indicator communication hole 49 is provided in the continuous surface 40C. The light emitter 70 is exposed from the indicator communication hole 49, so that the light emitter 70 can be visually recognized by the occupant.
Next, the cover 60 will be described.
As shown in
The cover 60 is formed of an entirely transparent member. Consequently, even in a state where the emergency call operation element 32 is covered with the cover 60, the occupant can visually recognize the emergency call operation element 32 without being obstructed by any region of the cover 60. Therefore, visual recognition of an interior of the cover 60 can improve.
The cover 60 comprises a flat plate 62 and an inclined portion 64.
The flat plate 62 covers a rear end of the emergency call operation element 32 in the front-back direction of the vehicle, and further extends rearward from the emergency call operation element 32. Furthermore, the flat plate 62 is formed almost in parallel with the operation panel 10 in a state where the emergency call operation element 32 is covered with the cover 60. The flat plate 62 has a uniform thickness dimension.
On opposite side surfaces of the flat plate 62 in the vehicle width direction, fitting portions 66 are provided, respectively. Each of the fitting portions 66 is molded in an annular form, and each fitting portion 66 has an insertion hole 67 extending through the portion in the vehicle width direction. The protruding portion 52 is inserted into each insertion hole 67.
Consequently, the cover 60 is pivotably supported by the protruding portion 52 of each support 50. That is, the cover 60 is openable and closable about each protruding portion 52 that serves as a rotary shaft, between a closed position to cover the emergency call operation element 32 and an opened position to open the emergency call operation element 32.
As described above, each of the supports 50 has flexibility, and each of the protruding portions 52 includes the tip inclined portion 54. Consequently, when a top surface 62A of the flat plate 62 is depressed with a predetermined pressure, each of the supports 50 is bent outward in the vehicle width direction, and each of the fitting portions 66 moves upward along each tip inclined portion 54. Afterward, each protruding portion 52 falls out of the insertion hole 67. Consequently, the cover 60 is released from a supported state held by a pair of protruding portions 52, and drops off.
Consequently, the emergency call operation element 32 is exposed and operable.
Thus, the top surface 62A of the flat plate 62 of the cover 60 is depressed with the predetermined pressure, so that the cover 60 can be immediately removed and the emergency call operation element 32 can be opened, for example, in case of emergency.
Note that, in the present embodiment, the cover 60 is formed so that the cover does not drop off in a case where the top surface 62A of the flat plate 62 receives a load having an amount less than a predetermined amount and so that the cover drops off in a case where the surface receives the predetermined amount of load or more. This can inhibit the emergency call switch 30 from being operated in case of non-emergency.
Furthermore, the emergency call operation element 32 is disposed so that the element is not operated in a case where the top surface 62A of the flat plate 62 is depressed.
In a case where the cover 60 is disposed in the opened position, a surface located at a rear end of the flat plate 62 in the front-back direction of the vehicle, that is, a rear end face 60A of the cover 60 abuts on the abutment inclined portion 48A of the stopper 48. That is, the cover 60 is stopped from rotating by the stopper 48.
Consequently, in the case where the cover 60 is disposed in the opened position, the cover 60 is inhibited from being in contact with the emergency call operation element 32. Consequently, the cover 60 and the emergency call operation element 32 can have improved durability.
The inclined portion 64 has a rear end connected to a front end of the flat plate 62, and has a front end extending to a position that covers a front side of the emergency call operation element 32, in a case where the cover 60 is disposed in the closed position.
Furthermore, the inclined portion 64 has a rear surface 64B provided along the operation surface 32A of the emergency call operation element 32 in the case where the cover 60 is disposed in the closed position. Consequently, the rear surface 64B is formed to incline upward at a predetermined angle from a rear surface 62B of the flat plate 62. Specifically, the rear surface 64B is inclined at the upward gradient from the vehicle front toward the vehicle rear in the front-back direction of the vehicle.
Similarly, a top surface 64A of the inclined portion 64 is formed to incline upward at a predetermined angle from the top surface 62A of the flat plate 62, and the top surface 64A is inclined at the upward gradient from the vehicle front toward the vehicle rear in the front-back direction of the vehicle.
That is, the inclined portion 64 is connected to the flat plate 62 to form the predetermined angle. Consequently, the inclined portion 64 is formed to incline upward at the predetermined angle to the operation panel 10.
The front end of the inclined portion 64 in the front-back direction of the vehicle includes a front-end abutment 68 protruding to a rear surface 64B side of the inclined portion 64. The front-end abutment 68 is provided at the whole front end of the inclined portion 64 in the vehicle width direction. When the cover 60 is disposed in the closed position, the front-end abutment 68 abuts on the bottom surface 40A of the emergency call operation element storage part 40. At this time, the operation surface 32A of the emergency call operation element 32 and the rear surface 64B of the inclined portion 64 opposite to the operation surface 32A are arranged via a predetermined gap. Consequently, the cover 60 can cover the emergency call operation element 32 without coming in contact with the emergency call operation element 32.
Grooves 69 are provided in opposite side surfaces of the inclined portion 64 that are located in the vehicle width direction, respectively. Each of the grooves 69 is molded in a groove form dented inward in the vehicle width direction, and each groove 69 is formed to extend in the front-back direction of the vehicle.
In the case where the cover 60 is disposed in the closed position, the grooves 69 engage with the engaging portions 46, respectively. Consequently, the cover 60 is fixed in the closed position.
When operating the emergency call operation element 32, a front end of the cover 60 in the front-back direction of the vehicle is drawn out downward with a predetermined force, the engaging portions 46 can be accordingly released from the grooves 69, respectively, and the cover 60 can be rotated and disposed in the opened position.
The inclined portion 64 has a thickness dimension decreased on the front side and increased on the rear side of the vehicle in the front-back direction of the vehicle. Consequently, the inclined portion 64 is provided in this thickness dimension so that the rear surface 64B has a predetermined angle to the top surface 64A of the inclined portion 64 in the front-back direction of the vehicle. That is, the top surface 64A and rear surface 64B of the inclined portion 64 are inclined at different angles of the upward gradient from the vehicle front toward the vehicle rear, respectively.
Consequently, in the case where the cover 60 is disposed in the closed position, light K from the light source 21 is emitted from the emergency call display 34, then transmitted through the cover 60 and thereby refracted. The refracted light K is directed in an emission direction from the emergency call display 34 toward the rear side in the front-back direction of the vehicle. That is, the light K is emitted from the cover 60 in a direction away from the rear-view mirror 2.
Thus, the light K is transmitted through the cover 60, so that the light K can be inhibited from being reflected in the rear-view mirror 2.
Note that, in the cover 60 of the present embodiment, the thickness dimension of the inclined portion 64 on the rear side is about the same as the thickness dimension of the flat plate 62.
In the present embodiment, when the emergency call switch 30 is not operated, the cover 60 is disposed in the closed position. At this time, external light from a windshield or the like, or reflected light of the external light reflected by the dashboard or the instrument panel may be directed to the operation panel 10 of the control device 1.
As described above, the cover 60 comprises the inclined portion 64 inclined at the upward gradient from the vehicle front toward the vehicle rear in the case where the cover is disposed in the closed position.
Consequently, the reflected light from the dashboard or the instrument panel or the external light from the windshield or the like can be inhibited from being radiated to the top surface 64A of the inclined portion 64 of the cover 60. Furthermore, in a case where the cover 60 is irradiated with the external light or the reflected light, total reflection by the top surface 64A of the inclined portion 64 of the cover 60 can be inhibited. Consequently, the occupant can always visually recognize the emergency call operation element 32 of the emergency call switch 30 via the cover 60.
According to the above described embodiment, such effects as described below are exhibited.
The emergency call switch 30 of the present embodiment is provided in the control device 1 of the vehicle ceiling part, and the emergency call switch 30 comprises the cover 60 that is openable and closable between the closed position to cover the emergency call operation element 32 and the opened position to open the element. Furthermore, the cover 60 comprises the inclined portion 64 formed of a member that transmits light, and inclined at the upward gradient from the vehicle front toward the vehicle rear in the closed position.
Consequently, in the case where the cover 60 is irradiated with the reflected light from the dashboard or the instrument panel or the external light from the windshield or the like, the total reflection by the top surface 64A of the inclined portion 64 of the cover 60 can be inhibited. Consequently, the occupant can always visually recognize the emergency call operation element 32 of the emergency call switch 30 via the cover 60.
Furthermore, according to the present embodiment, the cover 60 is formed of a member that entirely transmits light. Consequently, even in a state where the emergency call operation element 32 is covered with the cover 60, the occupant can visually recognize the emergency call operation element 32 without being obstructed by any region of the cover 60.
Additionally, according to the present embodiment, the control device 1 comprises the protruding portion 52 that protrudes inward in the vehicle width direction on each of the opposite sides in the vehicle width direction, the cover 60 comprises the fitting portion 66 that engages with and holds the protruding portion 52, and the cover 60 is openable and closable about the protruding portion 52 that serves as the rotary shaft. Consequently, the cover 60 is openable and closable about each protruding portion 52 that serves as the rotary shaft, between the closed position to cover the emergency call operation element 32 and the opened position to open the emergency call operation element 32.
Furthermore, according to the present embodiment, the stopper 48 that comes in contact with the cover 60 in the opened position is provided on the vehicle front side of the operation element. Consequently, in the case where the cover 60 is disposed in the opened position, the cover 60 can be inhibited from being in contact with the emergency call operation element 32, and the cover 60 and the emergency call operation element 32 can have improved durability.
Additionally, according to the present embodiment, the protruding portion 52 comprises the tip inclined portion 54 inclined at the upward gradient from an outer side toward an inner side in the vehicle width direction. Consequently, when the top surface 62A of the flat plate 62 of the cover 60 is depressed, the cover 60 can be immediately removed and the emergency call operation element 32 can be opened, for example, in case of emergency.
Furthermore, according to the present embodiment, in the operation surface 32A of the emergency call operation element 32, the emergency call display 34 through which light is transmittable is provided, and on a back side of the operation surface 32A, the light source 21 that illuminates the emergency call display 34 is provided. Consequently, the occupant can visually recognize the emergency call operation element 32 even in the dark place.
Additionally, according to the present embodiment, the cover 60 has the plate thickness decreased toward the vehicle front. Consequently, the light K is transmitted through the cover 60 and thereby refracted, and the light K can be inhibited from being reflected in the rear-view mirror 2.
Furthermore, according to the present embodiment, the operation surface 32A of the emergency call operation element 32 is inclined at the upward gradient from the vehicle front toward the rear. Consequently, in the case where the occupant sees the emergency call display 34, the distortion of the emergency call display 34 can be suppressed, and the visual recognition can improve.
Additionally, according to the present embodiment, the cover 60 is provided in the emergency call switch 30. Consequently, the incorrect operation of the emergency call switch 30 can be inhibited.
Next, a modification of the present invention will be described.
A control device 1 of the present modification is similar to the control device 1 of the above described embodiment, and is different in that a cover 160 comprises a pair of protruding portions 165 and each of supports 150 comprises a fitting portion 153.
The respective supports 150 of the present modification have flexibility, and have lower ends including the fitting portions 153, respectively, as shown in
The tip inclined portion 167 is an inclined surface inclined at a downward gradient toward a tip of the protruding portion 165, and the tip inclined portion 167 forms an upper surface of the protruding portion 165 in an up-down direction. That is, the protruding portion 165 is formed so that a width dimension in the up-down direction decreases as being toward the tip. The protruding portions 165 are inserted into the insertion holes 155, respectively.
Consequently, the cover 160 is rotatably supported by the respective supports 150.
As described above, the respective supports 150 have flexibility, and the protruding portions 165 include the tip inclined portions 167, respectively. Consequently, when a top surface 162A of the flat plate 162 is depressed, each of the protruding portions 165 moves upward, and each of the supports 150 is bent outward in the vehicle width direction along the tip inclined portion 167. Afterward, the protruding portions 165 fall out of the insertion holes 155, respectively. Consequently, the cover 160 is released from a supported state by a pair of supports 150, and drops off. Consequently, an emergency call operation element 32 is exposed and operable.
Thus, the top surface 162A of the flat plate 162 of the cover 160 is depressed, so that the cover 160 can be immediately removed and the emergency call operation element 32 can be opened, for example, in case of emergency.
Note that, in the present modification, each of the protruding portions 165 includes the tip inclined portion 167, but not limited to this, an inclined portion may be provided in each of the insertion holes 155. Furthermore, in this case, the tip inclined portion 167 does not have to be provided.
The above described embodiment illustrates one aspect of the present invention, and can be arbitrarily modified and applied without departing from a gist of the present invention.
In the above described embodiment, the operation surface 32A of the emergency call operation element 32 is inclined and provided, but not limited to this, the operation surface may be provided without being inclined.
Alternatively, the whole emergency call operation element 32 may be inclined so that the operation surface 32A is provided toward an occupant side.
In the above described embodiment, the switch 12 has the configuration where the operation element 20 is stored in the operation element storage part 16, but not limited to this, the operation element storage part 16 may not be provided, the opening 18 may be provided in the operation panel 10, and the operation element 20 may be inserted into the opening 18. Furthermore, in this case, the operation element 20 may have such a height dimension that the operation element does not protrude from the operation panel 10 and that the operation surface 20A forms about the same plane as in the operation panel 10.
Similarly, in the emergency call switch 30, the emergency call operation element storage part 40 may not be provided, the opening 42 may be provided in the operation panel 10, and the emergency call operation element 32 may be inserted into the opening 42.
Furthermore, in the above described embodiment, the light source 21 is provided in each operation element 20, and on the rear surface of the emergency call operation element 32, but not limited to this, illumination light may be guided from the light source provided at another position to each display 22 and the emergency call display 34 via a light guide material or the like.
Additionally, each display 22 and the emergency call display 34 are not limited to the member through which light is transmittable, and may be formed of, for example, a reflective material, a fluorescent material, or a phosphorescent material. In this case, each switch 12 or the emergency call switch 30 does not have to comprise the light source 21.
