Technical Field
The present application relates to a vehicle operation switch.
Background
In recent years, various operation switches have been mounted on front panels and the like in automobiles, and thus, the operation of various electronic devices such as audio devices and air conditioning devices in automobiles has been increasingly performed.
As an example of a vehicle operation switch mounted on a vehicle and operated by a finger of an occupant of the vehicle from above, a structure is known in which a push operation portion is disposed above the vehicle in a main body of the switch. Such a switch is used, for example, for an electric parking switch, a power window switch, and the like provided on the driver side of a center floor of a vehicle, and is required to prevent the invasion of water droplets and the like (for example, refer to patent document 1 (japanese patent application laid-open No. 2011-82079)).
Disclosure of Invention
Problems to be solved by the application
However, in the above-described conventional technique, although countermeasures against the influence of the intrusion of water drops such as rainwater, drink water, etc. on the switching operation are taken at the upper position of the switch, the following cases are not envisaged: in the case of a large amount of sweet seasoning, when a highly viscous liquid falls onto the switch, the liquid is caught along the switch body.
Particularly, when the thickness of the switch is made small, for example, when a connector portion is disposed below the switch body and an opening of the connector is opened in a horizontal direction by inserting a wire harness or the like to be connected into the connector portion, there is a case where dripping liquid is caught in the opening of the connector portion from the side of the switch body and intrudes into the inside of the opening. Thereby, flooding of the connector may result.
If the vehicle is inclined, the dripping liquid may be caught from the end portion inward and intrude into the opening of the connector portion. Thereby, flooding of the connector may result.
Accordingly, there is room for improvement in the prior art.
The present application has been made to solve the above problems, and an object of the present application is to improve safety of a vehicle operation switch. And, the safety of traffic is further improved to facilitate the development of sustainable transportation systems.
The present application has been made in view of the above-described circumstances, and an object thereof is to provide a vehicle operation switch capable of preventing water from entering an opening portion that is opened in a horizontal direction of a vehicle.
Means for solving the problems
In order to solve the above problems, the vehicle operation switch of the present application has the following structure.
(1) A vehicle operation switch according to an aspect of the present application is mounted on a vehicle, and operated by an occupant of the vehicle from above the vehicle to below by a finger of the occupant, and includes: a switch main body; a pressing operation portion disposed at a position in an upper direction of the vehicle in the switch main body; and a connector portion that protrudes from a lower end portion of the switch main body in a lower direction of the vehicle toward the lower direction of the vehicle, and has an opening portion that opens in a horizontal direction, wherein a contour shape of the connector portion in a plan view is formed smaller than a contour shape of the lower end portion of the switch main body, wherein the opening portion opens in an insertion direction into which an insertion portion of an end portion of a wire harness connected to the connector portion is inserted, and wherein a sagging waterproof side wall is formed at an outer side position of the lower end portion of the switch main body, the outer side position being separated from a side surface portion of the connector portion in a lateral direction intersecting the insertion direction.
(2) In the vehicle operation switch according to the aspect of (1), an intermediate surface portion may be formed between the waterproof side wall and the side surface portion of the connector portion at a position above the lower end portion of the waterproof side wall, the intermediate surface portion being located above the vehicle.
(3) In the vehicle operation switch according to the aspect of (1), a waterproof back wall may be formed at an outer position of the lower end portion of the switch body, the outer position being apart from a back surface portion of the connector portion in the insertion direction, the back surface portion being located on an opposite side of the opening portion.
(4) In the vehicle operation switch according to the aspect of (3), an intermediate surface portion located further upward in the vehicle than the lower end portion of the waterproof back wall may be formed between the lower end portion of the switch main body and the rear surface portion of the connector portion.
(5) In the vehicle operation switch according to the aspect (3) or (4), both ends of the waterproof back wall in the lateral direction may be connected to the waterproof side wall.
According to the aspect of (1), when the liquid falls onto the vehicle operation switch and enters from the pressing operation portion, the liquid flowing along the side portion of the switch main body flows along the outer side surface of the waterproof side wall at the lower end portion of the switch main body through the waterproof side wall. This prevents liquid from flowing back from the lower end portion of the switch body to the connector portion formed near the center of the outline in a plan view. Further, the liquid can be prevented from entering the connector portion. Thus, flooding of the connector can be prevented.
According to the aspect of (2), even when the liquid drips down to the lower end portion along the outer side surface of the waterproof side wall, the intermediate surface portion is located in the vehicle upper direction, that is, at a position higher than the lower end of the waterproof side wall. Thereby, the liquid does not adhere to the connector portion along the intermediate face portion. Meanwhile, even in the case where the vehicle is inclined, since the intermediate face portion is located at a position higher than the lower end of the waterproof side wall, it is possible to prevent the liquid from wrapping around the connector portion. This can prevent liquid from entering the connector portion.
According to the aspect of (3), when the liquid falls onto the vehicle operation switch and enters from the pressing operation portion, the liquid flowing along the rear surface portion of the switch main body is caused to flow along the outer side surface of the waterproof back wall at the lower end portion of the switch main body by the waterproof back wall. This prevents liquid from flowing back from the lower end portion of the switch body to the connector portion formed near the center of the outline in a plan view. Further, the intrusion of liquid into the connector portion can be prevented, and flooding of the connector can be prevented.
According to the aspect of (4), even when the liquid drips down to the lower end portion along the outer side surface of the waterproof back wall, the intermediate surface portion is located in the vehicle upper direction, that is, at a position higher than the lower end of the waterproof back wall. Therefore, the liquid does not adhere to the connector portion along the intermediate face portion. Meanwhile, even in the case where the vehicle is inclined, since the intermediate face portion is located at a position higher than the lower end of the waterproof back wall, it is possible to prevent the liquid from wrapping around the connector portion. This can prevent liquid from entering the connector portion.
According to the aspect of (5), in the switch main body, the waterproof side walls formed on both sides of the lower end portion in the lateral direction are connected to the waterproof back wall formed on the back side in the insertion direction. Thus, even in the connection portion, the liquid flowing along the lower end portion of the switch body can be caused to flow along the outer side surfaces of the waterproof side wall and the waterproof back wall at the lower end portion of the switch body by the waterproof side wall and the waterproof back wall. This prevents liquid from flowing back from the lower end portion of the switch body to the connector portion formed near the center of the outline in a plan view. Even when the vehicle is inclined, the intermediate surface portion is located higher than the lower ends of the waterproof side wall and the waterproof back wall. Therefore, by flowing along the outer side surfaces of the waterproof side wall and the waterproof back wall in three directions at the lower end portion of the switch main body, it is possible to prevent the liquid from wrapping from the lower end portion of the switch main body toward the connector portion formed near the center of the outline in a plan view. Thus, the intrusion of liquid into the connector portion can be prevented, and flooding of the connector can be prevented.
Effects of the application
According to the present application, it is possible to provide a vehicle operation switch capable of preventing water from entering an opening portion that is opened in a horizontal direction of a vehicle.

A connecting portion 22 is formed near the front lower end portion 20a1 of the mounting member 20. The connection portion 22 is, for example, a fixing recess 22a having a snap-fit structure. The fixing recess 22a may penetrate the lower end 20 a.
The switch body 11 is formed in a substantially rectangular parallelepiped shape. The lower end 11a of the switch body 11 is formed in a substantially rectangular shape as viewed in the Z direction. The peripheral outline of the lower end 11a of the switch body 11 formed substantially parallel to the XY plane is formed to have substantially the same height in the Z direction. A connector portion 13 is disposed near the center of the lower end portion 11a of the switch body 11 in a plan view.
The upper end 11b of the switch body 11 has a substantially rectangular outline as the lower end 11a. The peripheral outline of the upper end 11b of the switch body 11 is substantially the same height in the Z direction. A pressing operation portion 12 is disposed near the center of the upper end portion 11b of the switch body 11 in a plan view.
The four side portions of the front side portion 11c, the lateral side portion 11d, and the rear side portion 11e of the switch body 11 extend in the Z direction, that is, in the up-down direction. The front side surface portion 11c, the lateral side surface portion 11d, and the rear side surface portion 11e are substantially orthogonal to each other. The front side surface portion 11c is formed substantially parallel to the YZ plane in a front direction opposite to the insertion direction among the X directions. The lateral side surface portion 11d is formed substantially parallel to the XZ plane in a lateral direction substantially orthogonal to the insertion direction. The back surface portion 11e is formed substantially parallel to the YZ plane in a plane direction which is an insertion direction among the X directions.
A fixing protrusion 11c1 corresponding to the connection portion 22 is formed on the front side surface portion 11c of the switch main body 11. A fixing protrusion 11e1 corresponding to the connection portion 22 is formed on the back side surface portion 11e of the switch body 11. The fixing convex portion 11c1 and the fixing convex portion 11e1 form a snap structure together with the fixing concave portion 22a, and constitute the connecting portion 22. The switch main body 11 is fixed to a connection portion 22 formed near the front lower end portion 20a1 and the rear lower end portion 20e1 of the mounting member 20.
The pressing operation portion 12 is located at a position above the switch main body 11 in the Z direction. The pressing operation portion 12 is configured to be operated vertically so as to electrically connect and disconnect contacts inside the switch body 11 from each other. The pressing operation portion 12 is configured to be operable while maintaining a waterproof state with the switch main body 11.
The connector portion 13 is formed in a substantially rectangular parallelepiped shape. All the upper regions of the connector portion 13 are connected to the lower end portion 11a of the switch body 11. The connector portion 13 is formed with an opening portion 13c in the X direction. The opening 13c is inserted with an insertion portion 30 at the end of the harness connected to the connector 13. The X direction is the insertion direction.
The opening 13c of the connector 13 is connected to the lower end 11a of the switch body 11 through the opening upper portion 13c 1. The opening upper portion 13c1 is formed in the insertion direction so as to reduce the outline of the connector portion 13 as viewed along the Z direction, compared with the opening portion 13c. That is, the opening upper portion 13c1 is formed at a position that is set back in the insertion direction from the opening portion 13c.
A connector terminal 13t that conducts to the inside of the switch body 11 is provided inside the opening 13c of the connector portion 13. The connector terminal 13t is a member made of a metal such as copper. The connector terminal 13t extends along the X direction as the insertion direction.
The outline of the connector 13 in plan view, i.e., in Z direction, is smaller than the outline of the lower end 11a of the switch body 11. The connector portion 13 is disposed substantially at the center of the lower end portion 11a of the switch body 11 as viewed in the Z direction. That is, the connector portion 13 is separated from the front side surface portion 11c, the lateral side surface portion 11d, and the rear side surface portion 11e of the switch body 11 when viewed in the Z direction, and is positioned near the center of the outline of the switch body 11 when viewed in the Z direction.

The opening 13c and the front side surface 11c of the connector 13 may be closer to each other than the distance between the back side surface 11e and the outline of the connector 13 viewed in the Z direction.
The waterproof side wall 14 extends downward from a lateral side surface portion 11d in the periphery of the lower end portion 11a of the switch main body 11. The waterproof side wall 14 extends in the X direction. The waterproof side wall 14 is provided on the right and left ends of the lower end portion 11a in the Y direction over substantially the entire length of the lateral side portion 11d in the X direction. The waterproof side wall 14 is substantially parallel to the lateral side surface portion 11 d. The waterproof side wall 14 is substantially parallel to the side surface portion 13d of the connector portion 13. The waterproof side wall 14 is not connected to the connector portion 13. The lower end 14a of the waterproof side wall 14 is located below the lower end 11a of the switch main body 11 in the Z direction. The lower end 14a of the waterproof side wall 14 is located above the lower end 13a of the connector 13 of the present embodiment in the Z direction, but is not limited to this configuration. The front end portion 14c of the waterproof side wall 14 is located forward of the opening portion 13c of the connector portion 13 of the present embodiment in the X direction. The rear end of the waterproof side wall 14 is connected to a waterproof back wall 15. The waterproof side wall 14 and the waterproof back wall 15 are connected without a gap over the entire length in the Z direction.
The waterproof back wall 15 extends downward from the back side surface portion 11e in the periphery of the lower end portion 11a of the switch body 11. The waterproof back wall 15 extends in the Y direction. The waterproof back wall 15 is located forward of the back side surface portion 11e in the X direction, but is not limited to this configuration. The waterproof back wall 15 is substantially parallel to the back side surface portion 11 e. The waterproof back wall 15 is substantially parallel to the back surface portion 13e of the connector portion 13. The waterproof back wall 15 is not connected to the connector portion 13, but is not limited to this structure. The lower end portion 15a of the waterproof back wall 15 is located below the lower end portion 11a of the switch main body 11 in the Z direction. The lower end portion 15a of the waterproof back wall 15 is located at substantially the same height as the lower end portion 13a of the connector portion 13 of the present embodiment in the Z direction, but is not limited to this configuration. Both ends of the waterproof back wall 15 in the Y direction are connected to the waterproof side wall 14. The waterproof back wall 15 is connected to the waterproof side wall 14 without any gap over the entire length in the Z direction.
An intermediate surface 17 is formed between the waterproof side wall 14 and the waterproof back wall 15 and the connector portion 13. The intermediate face 17 is formed at the lower end 11a of the switch body 11. The intermediate face portion 17 is formed between the waterproof side wall 14 and the side face portion 13d of the connector portion 13. The intermediate face portion 17 is formed between the waterproof back wall 15 and the back face portion 13e of the connector portion 13.
The intermediate surface 17 is located above the lower end 14a of the waterproof side wall 14 in the Z direction. The entire area of the intermediate face 17 is formed at a position higher than the lower end 14a of the waterproof side wall 14 in the Z direction. The intermediate surface 17 is located above the boundary between the side surface 13d and the lower end 13a of the connector 13 in the Z direction. The intermediate surface 17 is formed at a position higher than the boundary between the side surface 13d and the lower end 13a of the connector 13 in the Z direction.
The intermediate surface 17 is located above the lower end 15a of the waterproof back wall 15 in the Z direction. The entire area of the intermediate face 17 is formed at a position higher than the lower end portion 15a of the waterproof back wall 15 in the Z direction. The intermediate surface 17 is located above the boundary between the rear surface 13e and the lower end 13a of the connector 13 in the Z direction. The intermediate surface 17 is formed at a position higher than the boundary between the rear surface 13e and the lower end 13a of the connector 13 in the Z direction.
The intermediate surface 17 of the present embodiment may be formed in a simple plane, and may have a predetermined concave-convex shape as long as it is positioned higher than the lower end 14a of the waterproof side wall 14 and the lower end 15a of the waterproof back wall 15. For example, as shown in fig. 4, the intermediate surface 17 formed between the back surface 13e of the connector 13 and the waterproof back wall 15 may have a protrusion 17e1 protruding downward corresponding to the connector 13.
According to the vehicle operation switch 10 of the present embodiment, the waterproof back wall 15 and the waterproof side wall 14 are formed at the lower end portion 11a of the switch main body 11, and the intermediate surface portion 17 is formed between the waterproof back wall 15 and the waterproof side wall 14 and the connector portion 13. This can prevent the liquid from entering the connector portion 13.
When the liquid falls to the vehicle operation switch 10 mounted on the vehicle, the liquid drops from the opening 21 of the mounting member 20 that opens at the upper surface 20b, as indicated by the arrows in fig. 1 and 2. Then, the liquid that has dropped from the attachment member 20 onto the vehicle operation switch 10 drops downward from the vicinity of the pressing operation portion 12 and from the upper end portion 11b of the switch main body 11, as indicated by arrows in fig. 1 and 2. Further, the liquid drops down along one or more of the front side surface 11c, the lateral side surface 11d, and the rear side surface 11 e.
Here, as shown by the arrow in fig. 1, when the liquid falls along the lateral side surface portion 11d, the liquid that has fallen to the lower end portion 11a of the switch main body 11 falls along the outer side surface of the waterproof side wall 14 that is substantially coplanar with the lateral side surface portion 11 d. After the liquid falling along the outer surface of the waterproof side wall 14 falls to the lower end portion 14a, the intermediate surface portion 17 falls to a position below the vehicle operation switch 10 because it is located higher than the lower end portion 14a in the Z direction.
At this time, since the lower end portion 14a is separated from the connector portion 13, even if the lower end portion 14a is located at a position higher than the lower end portion 13a of the connector portion 13, the liquid falls down to a position lower than the vehicle operation switch 10.
Thus, the liquid flowing down along the lateral side surface 11d and the waterproof side wall 14 does not intrude into the opening 13c of the connector 13, and no electrical failure occurs in the connector 13. Meanwhile, even if the liquid having high viscosity and being liable to be wound around from the lower end portion 11a falls down to the lower end portion 14a along the outer side surface of the waterproof side wall 14, the liquid is separated by the intermediate surface portion 17, and thus does not intrude into the opening portion 13c of the connector portion 13, and electrical failure does not occur in the connector portion 13.
Further, by positioning the front end portion 14c of the waterproof side wall 14 in front of the opening portion 13c of the connector portion 13 in the X direction, the liquid does not intrude into the opening portion 13c even when the liquid approaches the front end portion 14 c.
When the liquid drops down along the back side surface portion 11e as shown by the arrow in fig. 2, the liquid that drops down to the lower end portion 11a of the switch body 11 drops down along the outer side surface of the waterproof back wall 15 that is closer to the connector portion 13 than the back side surface portion 11 e. Further, the liquid falling along the outer side surface of the waterproof back wall 15 falls down to the lower end portion 15a, and then falls down to a position lower than the vehicle operation switch 10 because the intermediate surface portion 17 is located higher than the lower end portion 15a in the Z direction.
At this time, since the lower end portion 15a is separated from the connector portion 13, even if the lower end portion 15a is located at substantially the same height position as the lower end portion 13a of the connector portion 13, the liquid falls down to a position lower than the vehicle operation switch 10.
Thus, the liquid flowing down along the lateral side surface portion 11d and the waterproof back wall 15 does not intrude into the opening portion 13c of the connector portion 13, and no electrical failure occurs in the connector portion 13. Meanwhile, even if the liquid having high viscosity and being liable to be wound around from the lower end portion 11a falls down to the lower end portion 15a along the outer side surface of the waterproof back wall 15, the liquid is separated by the intermediate surface portion 17, and thus does not intrude into the opening portion 13c of the connector portion 13, and electrical failure does not occur in the connector portion 13.
As described above, in the present embodiment, the vehicle operation switch 10 includes the switch body 11, and the connector portion 13 having the opening portion 13c that opens in the horizontal direction is disposed below the switch body 11 via the waterproof side wall 14, the waterproof back wall 15, and the intermediate surface portion 17. By this, the wall portion is raised around the connector portion, thereby preventing liquid entering from the finger-inserted space from flooding the connector portion 13.
In the present embodiment, the waterproof side wall 14 is formed so as to be connected to the lateral side surface portion 11d, but the present application is not limited thereto. The configuration is not limited to the above as long as the intermediate surface 17 can be formed between the connector 13 and the connector 13 in a state of being separated from the connector 13. The outline shape of the lower end portion 14a of the waterproof side wall 14 may be appropriately set as long as the lower end portion 14a is positioned below the intermediate surface portion 17.
Similarly, the waterproof back wall 15 is formed so as to be connected to the back side surface 11e, but is not limited thereto. The configuration is not limited to the above as long as the waterproof back wall 15 can be formed between the connector 13 and the connector 13 in a state of being separated from the connector 13. The outline shape of the lower end portion 15a of the waterproof back wall 15 may be appropriately set as long as the lower end portion 15a is positioned below the intermediate surface portion 17.
