Description

  In general, the operation of turning on or off the vehicle interior light from the door body is mainly linked to the opening / closing operation of the side door of the vehicle, and the interior light of the vehicle is turned on when the side door is open, When is closed, the room light switches off. According to the present invention, in the door switch, the front end surface of the shaft and the rubber cover are not in direct contact with each other, so that the lighting or extinguishing operation of the interior lamp in the vehicle can be stably turned on and off for a long time by opening and closing the door of the automobile It is related with the door switch for vehicles which can do.

  The car is running or stopped and the car door is normally closed. When the car is closed, the room light is off. When the car stops and a person opens the door to go outside, or when the car stops and the car door opens. In this state, the door switch is turned on, and the interior lamp in the vehicle is turned on.

Japanese Utility Model Publication No. 3-15429

  The waterproof push switch disclosed in Japanese Utility Model Laid-Open No. 3-15429 is provided in [Operation] to insulate the waterproof cap by engaging and locking the locking recess (hole) of the waterproof cap with the locking pin of the insulating cylinder. There is a description that it can be attached to the cylinder, and the waterproof cap cannot be removed unreasonably even when the screw-fastened portion of the waterproof cap is turned up at the time of screwing.

  However, the conventional device has a structure in which the waterproof cap 9 and the front end surface of the pressing body are in direct contact with each other, and thus there is a problem that the waterproof cap 9 cannot withstand long-term use due to damage or deterioration of the waterproof cap 9.

  In view of the above, the present invention avoids direct contact between the inner surface of the rubber cover or the cover made of a synthetic resin made of a heat-flexible synthetic resin and the tip end surface of the shaft, and the rubber cover or the synthetic resin. When the side door of the vehicle is closed by providing a smooth member made of synthetic resin or heat-resistant material with low frictional resistance between the inner surface of the cover and the front end surface of the shaft, the inner wall surface (iron plate) of the door The contact between the ground terminal and the contact is brought into a non-contact state, and the room light is kept off. On the other hand, when the side door is opened, the contact and the ground terminal are in contact with each other, the door switch forms a lighting circuit, and the room light is turned on. By providing an arc-shaped cushioning material with low frictional resistance and excellent durability between the rubber cover and the shaft end surface, eliminating the direct contact between the shaft end surface and the rubber cover, the rubber cover In addition to preventing damage, the durability of the rubber cover increases for a long period of time, and a comfortable driving is guaranteed for the driver of the vehicle. An object of the present invention is to provide a vehicle door switch that can be reliably maintained for a long time.

  The present invention relates to a vehicle door switch mounted on a vehicle body side at a position opposite to a side door body that opens and closes a vehicle side door, and a front end surface of a rubber cover or a synthetic resin cover of the vehicle door switch is A synthetic resin or synthetic rubber cross-section arc-shaped cushioning material that has a convex surface that can be expanded and contracted and has elasticity that abuts on the inner surface central portion and its vicinity peripheral portion is fitted, and the tip end surface is fitted to the cross-section arc-shaped cushioning material The shaft has a curved surface shape, the shaft projects horizontally from the middle, has a cylindrical portion that hangs downward, and the shaft located at the lower center is formed into a shaft that is thinner than the tip, A helical spring is mounted around the thin shaft, the helical spring hangs below the lower end of the thin shaft, and the positive terminal is always electrically connected to the contact. In addition, the earth terminal is connected to the contact, and when the door switch is pushed by the side door, the circuit of the room light is turned off and turned off, and when the side door is opened, the circuit of the room light is turned on and the room light is turned on. It is a door switch for vehicles characterized by having a structure which lights up.

  According to a second aspect of the present invention, the arc-shaped cushioning material according to the first aspect is fixed to the inner peripheral surface of the rubber cover so that the convex inner surface does not separate from the arc-shaped or curved rubber cover. The vehicle door switch according to claim 1, wherein the vehicle door switch is held in an elastic shape.

  The present invention is fitted with a synthetic resin or rubber-made substantially arc-shaped cushioning material in contact with the central part and the peripheral part of the inner surface of the inverted saddle-shaped rubber cover, and the synthetic resin or rubber-made sectional arc shape A shaft having a curved surface shape on the front end is brought into contact with the buffer inner surface, and the shaft is provided with a cylindrical portion that projects horizontally from the middle and hangs downward, and the shaft located at the lower center is thinner than the front end. A helical spring is provided around the thin shaft, the helical spring hangs below the lower end of the thin shaft, and the plus terminal is always electrically connected to the contact. Since the earth terminal is connected to the contact, the vehicle door switch attached to the vehicle body has a frictional engagement between the tip surface of the spherical shaft and the inner surface of the rubber cover. Even when traveling on rough roads or mountain roads where the vehicle body moves up and down by fitting a small cross section arc cushioning material made of synthetic resin or synthetic rubber, it is between the tip of the shaft and the rubber cover. Since the rubber cover is protected by the synthetic resin or synthetic rubber cross-section arc-shaped cushioning material because it is in contact with the inner surface of the synthetic resin or synthetic rubber sectional arc-shaped cushioning material with low frictional resistance, rubber The durability of the cover is greatly improved, and it is not necessary to replace the rubber cover over a long period of time.

  Moreover, even when temporarily taking a break during traveling on bad roads, mountain roads, etc., the shaft does not directly contact the rubber cover, so even when stopping on mountain roads, bad roads, etc. as before, By opening the side door, the interior light is turned on, and it is possible to travel on a mountain road or the like with a sense of security.

  Furthermore, the lower peripheral edge of the synthetic resin or synthetic rubber cross-section arc-shaped cushioning material is firmly held by the collar provided on the inner peripheral edge of the rubber cover, so it can be synthesized even when traveling on rough roads and other roads. Since the resin or synthetic rubber cross-section arc buffer material is securely held by the annular flange provided on the rubber cover, there is no risk of the synthetic resin or synthetic rubber cross-section arc buffer material falling off, It can be used for a long time.
