It is related with the technology to adhere to.

Japanese Utility Model Publication No. 5-37577 Japanese Utility Model Publication No. 5-34046 Japanese Utility Model Publication No. 5-32119 Japanese Utility Model Publication No. 5-35487 Japanese Utility Model Publication No. 5-10088 Japanese Utility Model Publication No.5-10087 Japanese Utility Model Publication No. 6-6102 JP 2003-327041 A

  In general, an automobile has this state when the door is not completely closed, in other words, when the door is open or slightly open (hereinafter referred to as “half door state”). Room lights such as a door lamp and a room lamp that are lit when the door is open are provided for passengers who are alerted to the passenger when the door is open and get on and off the vehicle at night.

  For this reason, when passengers get on and off a car parked and parked on the road and the door is opened, or when loading and unloading luggage by opening the door, these interior lights are lit, especially at night. The person can visually recognize these lit indoor lights, and can recognize for the time being that the door may be in an open state.

  However, since the interior light is provided mainly for the passengers of the automobile including the driver, it is not always sufficient as a function for warning the outside approaching person that the door is open. is not. In other words, the door lamp is mounted on the interior side surface of the door so that it can illuminate its feet when a passenger gets in and out of the vehicle. Is difficult to see unless the door is open to nearly 90 degrees, and may be hidden by passengers getting on and off, etc. Even if the room lamp is lit at this time, the amount of light is usually low It is not possible to illuminate the open end of the door that is in shortage, and it is difficult to recognize whether the passenger gets out of the car from the rear of the car.

  Therefore, in order to solve such problems, a metal plate and a printed board on which a plurality of light emitting elements are fixed in parallel are provided in the lamp body of the display device, and the front surface of the light emitting element is covered with a translucent resin. There has been proposed a vehicle door open / close warning indicator lamp that forms a bent portion (concave portion) that disperses bending stress at an appropriate interval at a position corresponding to the mounting portion (Japanese Utility Model Laid-Open No. 5-37577). In this device, when the lamp body is bent and deformed, the bending stress is not concentrated on the soldering fixing portion of the light emitting element by the bent portion, and the fixing portion is peeled off from the printed board, or the power supply circuit to the light emitting element Can be prevented from being disconnected. However, although the lamp body formed from a metal plate can be bent in a bendable direction, it can hardly be twisted, so it can only be mounted on the flat part of the open end of the automobile door. Since it cannot be mounted on a complicated curved surface, the mounting position of the display tool is limited to the central portion of the door open end.

  In addition, the lamp body of the display device has a printed circuit board on which the back surface is formed in a flat shape and a metal plate and a plurality of light emitting elements are mounted on the front surface in order to secure an adhesive surface with the door open end, and light emission It is configured by overlaying a transparent resin or the like covering the front surface of the element. Therefore, the total thickness of all components such as the lamp body, the printed board, the light emitting element, and the transparent resin is the thickness of the display tool. Therefore, in order to reduce the thickness of the display device, the thickness of each component must be reduced. However, there is a limit to this.

  Further, the display device includes a printed board in which a metal plate and a plurality of light emitting elements are fixed in parallel in the lamp body, and a bent portion is formed at a position corresponding to the mounting portion of the light emitting element of the lamp body. Therefore, if the adhesion between the door open end and the lamp body is poor, water that has entered between the body panel and the door panel may pass through the bent part from the back side of the lamp body and reach the printed circuit board. There was a problem of poor water resistance.

  Furthermore, for the purpose of showing the position of the door open end to the outside approaching person, the indicator is positioned at the door open end that can be visually recognized even in a half-door state, specifically, the door outer shown in FIG. In a door 301 including a panel 302 and a door inner panel 303, a corner portion 305 (hereinafter simply referred to as a “corner portion”) of a door end surface formed corresponding to the shape of the corner portion of the center pillar 304 is formed. It is preferable to attach along. However, since the lamp body of the display device can be bent only in a bendable direction, the display device cannot be attached along a complicated curved surface of the corner portion at the door open end.

  In addition, a metal plate and a printed circuit board are housed in the lamp body, the front surface of the light-emitting element is covered with a translucent resin, and both side portions corresponding to the constituent parts of the light-emitting element on both sides along the longitudinal direction of the metal plate A vehicle door open / close warning indicator lamp (Japanese Utility Model Laid-Open No. 5-34046) and a printed circuit board on which a plurality of light emitting elements are fixed in parallel are internally fixed to the lamp body, and are attached to the front opening edge of the lamp body. A vehicle door open / close warning indicator lamp (Japanese Utility Model Laid-Open No. 5-32119) has been proposed in which a lens body is slidably fitted and a holding member is formed at a side end of the lamp body. However, these display devices have the same problem because they have a structure in which a printed circuit board is housed in a plate-like lamp body, similar to the display device.

  In addition, the indicator lamp is fixed to the mounting surface of the vehicle by inserting and fixing the terminal of the indicator lamp to the connector on the vehicle side, and at the same time, the indicator lamp and the power source on the vehicle side can be electrically connected. A plurality of light-emitting elements are fixed in parallel on a printed circuit board at one end of a vehicle door opening / closing warning indicator (Japanese Utility Model Publication No. 5-35487) or a door molding fixed to the surface of a door that opens and closes an opening of a vehicle. The vehicle door opening / closing warning indicator lamp (Japanese Utility Model Laid-Open No. 5-10088) is constructed such that the indicator lamp portion is formed by covering the front surface of the light emitting element with a lens, and the lens is desired on the side of the door opening / closing side. ) Has been proposed. However, in order to attach this indicator light to an automobile, it is necessary to process the door opening end portion of the automobile in advance and the door molding of the latter in advance, which is problematic for the automobile owner to attach.

  Furthermore, a door fixing plate ridge is provided for elastically fitting and fixing the indicator lamp portion to the edge of the fitting end surface of the door that opens and closes the opening of the vehicle, and the indicator lamp portion is edged by the door fixing plate ridge. A vehicle door open / close warning indicator lamp having a push button switch or the like for turning on, blinking, or turning off the indicator lamp in response to opening / closing of the door has been proposed (Japanese Utility Model Laid-Open No. 5-10087). Issue gazette). However, when this indicator light is fixed to the edge of the fitting end surface of the door, there is a problem that a part of the indicator light is exposed to the outside of the side of the door of the automobile and the appearance of the automobile is impaired.

  Furthermore, an automobile rear-end collision prevention device with a blinking lamp at the open end of a door or a warning indicator as an alarm buzzer has been proposed (Japanese Utility Model Laid-Open No. 6-6102). However, since this indicator can only be attached to the center of the door open end, there is a problem that the indicator cannot be attached along the complicated curved surface of the corner at the door open end.

  All the prior arts mentioned above are provided with a hinge part between the door opening of the automobile and one end of the door, and the door is pivoted around the hinge part to open and close (hereinafter referred to as “hinge type”). It is designed to be applied to doors.

  On the other hand, the door is separated from the door opening, and the door is slid on the rail along the outer surface of the body panel of the automobile (hereinafter referred to as “sliding type”). Supplied with a wire harness routed from the vehicle body to the sliding door, an auxiliary machine that can be operated by the electric power sent through the wire harness is mounted on the sliding door, and the light emission that brightly illuminates the periphery of the sliding door as an auxiliary machine In some apparatuses, when the sliding door is opened, the light source portion can directly irradiate downward or rearward of the sliding door (Japanese Patent Laid-Open No. 2003-327041). As a result, when the passenger gets on and off the vehicle body, the periphery of the sliding door is brightly illuminated, so that the peripheral portion of the sliding door is easily recognized. In addition, it is possible to easily confirm that the approaching person from the rear of the vehicle body is in the open state. However, since the wire harness is routed from the vehicle body side to the sliding door, the wire harness bites between the opening of the vehicle body and the sliding door, or when the passenger gets on and off the wire harness It gets caught in your limbs and luggage. Furthermore, there has been a problem that it is impossible for a person approaching outside from the front of the vehicle body to confirm that the sliding door is in an open state.

  The present invention has been made in view of such problems, and the object of the present invention is to enable the display device to be easily attached along the complicated curved surface of the corner portion at the door open end, and from the rear side. An object of the present invention is to provide an open door end portion display device for an automobile that can clearly display the door open end portion and ensure water resistance for an external approaching person.

  Furthermore, in the case of a sliding door, there is provided an automobile open door end display device capable of displaying a door end not only to an external approaching person from the rear but also to an external approaching person from the front. There is.

  In order to achieve the above object, an automobile door open end display device according to the present invention has a self light emitting element attached to an end of a car door and blinks or lights the self light emitting element simultaneously with the opening of the car door. A door opening end display device for an automobile that displays the opened door end portion (door opening end portion) when the door is opened, and the light-emitting element is formed in a flexible thin rod shape. The flexible rod-shaped light emitter, and a flexible transparent resin having flexibility, covering the flexible rod-shaped light emitter over its entire length, and the mounting surface of the door end when the light-emitting element is mounted A rod-like or belt-like soft transparent covering that is bent and deformed along a curved shape, and the soft transparent covering provided continuously or intermittently over the entire length in the length direction of the soft transparent covering. Deformable following the bending deformation of the cover It is characterized in that it has a tongue mounting portion.

  In such an automobile door open end display device according to the present invention, the self-luminous element attached to the automobile door end is composed of a flexible rod-like light emitter, a soft transparent covering, and a flat attachment portion. ing.

  The flexible rod-shaped light emitter includes a core electrode for supplying electric charges to the self-light-emitting element, a cylindrical transparent insulating synthetic resin containing luminescent fine particles covering the core electrode, and the insulating synthetic resin A load electrode that supplies electric charges to the self-luminous body separately from the core electrode that is spirally wound around the electrode, and an AC voltage must be applied between the core electrode and the load electrode. I must. As a result, the light emitting fine particles receive an alternating electric field to emit light, and the flexible rod-shaped light emitter can be turned on.

  The soft transparent covering is preferably made of a soft and transparent synthetic resin such as polyethylene. And in order to prevent the penetration | invasion of the water to the said flexible rod-shaped light-emitting body, you have to coat | cover over the full length of the said flexible rod-shaped light emitter. Thereby, it becomes possible to ensure the waterproof performance of the self-luminous element.

  The flat mounting portion is preferably formed by integrally forming the soft transparent covering body continuously or intermittently over the entire length in the length direction of the soft transparent covering body, and each is made of the same material. Alternatively, different materials may be used. Moreover, you may form the said flat attachment part which has a clamping part which can hold | maintain the said self-light-emitting element separately from the said soft transparent coating | covering body. Furthermore, the said soft transparent coating | coated body may be shape | molded in a strip | belt shape, and the said flat attachment part may be formed in a contact surface with the attachment surface of the said door edge part. Even if the flat mounting portion is formed by any method, the mounting surface of the door end and the flat mounting portion are brought into surface contact with each other, and the flat mounting portion is made to the mounting surface, and thus the self-light-emitting device. The element can be firmly fixed to the mounting surface by means such as adhesion.

  As described above, when both the flexible rod-shaped light emitter and the soft transparent cover are formed of a flexible material, the mounting surface of the door end has a complicated curved surface. Even if it exists, the said self-light-emitting element can be deformed along the said attachment surface. In addition, by forming the soft transparent covering body in the shape of a thin bar or strip having the flat mounting surface, the self-luminous element can be attached to the corner of the door end, and the self-luminous element is attached to the front. It is possible to store the door in a slight gap such as between the rear end of the seat door and the center pillar and between the rear end of the rear seat door and the tire house so as not to obstruct the opening and closing of the door. As a result, the self-luminous element does not hinder the door from being closed or impair the appearance of the automobile.

  Further, since the soft transparent covering is covered over the entire length of the flexible rod-like light emitter, the entire length of the self-light-emitting element functions as a light-emitting portion, and a surface that does not transmit light, that is, a door end portion. It can be visually recognized from all directions other than the mounting surface. In addition, by attaching the self-luminous element to the corner of the door end, the rear door is secured while ensuring sufficient visibility from the half door state where the door is slightly open to the state where it is fully open. It is possible to inform the outside approaching person from the end. Furthermore, since the soft transparent covering is covered over the entire length of the flexible rod-like light emitter, the self-light-emitting element is sufficient for water that has entered through the gap between the body and the door during running in the rain or during a car wash. It is possible to exhibit excellent waterproof performance that can be withstood. In addition, the color of the soft transparent covering is preferably easily visible to humans and can be appropriately selected.

  As the self-luminous element, in addition to the soft transparent covering, a rod-shaped light emitting portion formed of a soft and transparent synthetic resin such as polyethylene and the light emitting portion is irradiated from both ends of the light emitting portion. By doing so, you may form a flexible light-emitting body from light emitting elements, such as LED which light-emits the said light emission part. Even in this case, the flat mounting portion is formed by integrally or intermittently forming the light emitting portion over the entire length in the length direction of the light emitting portion, and the same material or different materials are applied to each. Can do. Moreover, you may form the said flat attachment part which has a clamping part which can hold | maintain the said light emission part separately from the said light emission part. Thereby, the mounting surface of the door end and the flat mounting portion are brought into surface contact, and the flat mounting portion is bonded to the mounting surface, and thus the flexible light emitter is bonded to the mounting surface. It can be firmly fixed by means.

  Furthermore, the self-luminous element is set to have a width, a length, and a thickness capable of covering a plurality of the flexible rod-shaped light emitters arranged in parallel and all the flexible rod-shaped light emitters. You may comprise by the said strip-shaped soft transparent coating body. Even in this case, the soft transparent covering is preferably formed of a soft and transparent synthetic resin such as polyethylene. And since the said soft transparent covering body is strip | belt shape, it is good to make the surface which carries out surface contact with the attachment surface of a door edge part function as the said flat attachment surface. Thereby, even when a plurality of the flexible rod-like light emitters are applied, the self-light-emitting element can be deformed along the curved surface of the mounting surface of the door end, and further, the self-light-emitting element is It can be firmly fixed to the mounting surface of the door end by means such as adhesion.

  Further, the plurality of flexible rod-shaped light emitters may all emit light of the same color or different colors, and the color to be emitted can be appropriately selected. Further, the plurality of flexible rod-shaped light emitters may be made to emit light at the same timing or all at the same time as the door of the automobile is opened, and the timing and order of light emission are appropriately set. It is possible. Thereby, it is possible not only to increase the amount of light of the self-light-emitting element, but also to improve the visibility of the self-light-emitting element, rather than configuring the self-light-emitting element with a single flexible rod-shaped light emitter. The flashing or lighting of the self-luminous element can be clearly distinguished from the lighting and flashing of the combination lamp provided at the rear of the automobile.

  In the present invention, the control means for blinking or lighting the self-luminous element at the same time as the door is opened may be any means provided with a door switch that is turned on and off in conjunction with the opening and closing of the door. The control means for turning on the room lamp with the vehicle-mounted battery as a power source when it is in an open state may be used as it is, and an electric circuit for supplying power to the door lamp may be connected in parallel or in series with the door lamp, Further, a control unit such as a dedicated on / off switch other than the control unit for the indoor lamp may be provided by using the on-board battery as a power source or mounting a storage battery separately from the on-vehicle battery.

  And when using a vehicle-mounted battery or a storage battery, and providing a dedicated control means different from the one for room lights, as this control means, electric power (current and / or voltage) supplied from the vehicle-mounted battery or storage battery It is preferable to include a power supply circuit for stabilizing the lighting and a lighting / flashing circuit for flashing or lighting the self-light-emitting element. In addition, an oscillation circuit that converts a DC voltage supplied from the in-vehicle battery into an AC voltage, or a voltage supplied from the in-vehicle battery is boosted to a voltage at which the self-emitting element can emit light according to the type of the self-emitting element. A booster circuit or the like may be provided.

  Furthermore, it is preferable that the lighting / flashing circuit for flashing or lighting the self-light-emitting element simultaneously with the opening of the door of the automobile is for flashing the self-light-emitting element. The number of blinks per unit time of the self-luminous element is preferably set to be different from that of a hazard lamp of an automobile used by blinking. As a result, it is possible to clearly distinguish between blinking or lighting of the self-luminous element and lighting and blinking of a combination lamp provided at the rear of the automobile.

  When the present invention is applied to a hinged door, even when the hinged door is in an open state, an electric circuit for lighting a room lamp such as a room lamp or a door lamp is provided. Can be supplied from the electric circuit by connecting to the control means of the present invention. However, when the present invention is applied to a sliding door, no power is supplied to the door when the sliding door is in an open state, or no power is supplied to the sliding door itself regardless of the open / closed state of the sliding door. Since some vehicles are not supplied, it is necessary to provide a circuit for supplying power to the sliding door when the door is opened.

  Therefore, it is composed of an auxiliary power source mounted on the sliding door and a switch unit connected between the auxiliary power source and the in-vehicle battery. When the sliding door is closed, the auxiliary power source is charged by the in-vehicle battery. In the open state, it is preferable to provide an auxiliary power supply circuit for discharging the electric power charged in the auxiliary power source to the control means to blink or turn on the self-light-emitting element. In this configuration, the switch unit must be configured to energize the auxiliary power source and the in-vehicle battery when the sliding door is closed, and to interrupt the auxiliary power source and the in-vehicle battery when the sliding door is open. In addition, the auxiliary power source must be capable of discharging power charged by the on-vehicle battery and supplying sufficient power for blinking or lighting the self-luminous element. The auxiliary power circuit eliminates the need to connect the wiring connecting the in-vehicle battery and the auxiliary power source when the sliding door is in an open state, and wiring is provided between the door opening and the sliding door. It is possible to prevent biting or short-circuiting, and to prevent the wiring from being caught on the passenger's limbs or luggage when the passenger gets on and off, and the present invention can also be applied to a sliding door Become.

  In the case of a sliding door, the self-luminous element may be attached to a front door end or a rear door end, or a front and rear door end of the sliding door. Thereby, it becomes possible to display the edge part of a sliding door with respect to the external approaching person from the front and back, and to reduce contact with a passenger and an external approaching person.

  The auxiliary power source is not limited to a sliding door, and can be applied to an elevating device that is installed in the rear part of a vehicle such as a truck for loading loads and used for loading and unloading loads. In this case, the self-luminous element may be attached to the end of the lifting device. Accordingly, when the lifting device is raised as a load is loaded, or when the lifting device is lowered as a load is loaded, the end of the lifting device is displayed to an external approaching person to call attention. it can.

  Further, in the present invention, warning sound means such as a speaker that emits a warning sound when the self-light-emitting element blinks or lights in addition to the self-light-emitting element. This warning sound means also needs to emit a warning sound at the same time as the door is opened, like the self light emitting element, and is preferably controlled in the same manner as the self light emitting element by the control means of the self light emitting element. By using this warning sound means together with a self-luminous element, it is possible to warn of the door open state not only visually but also from the auditory sense. The position of the end can be known more reliably.

  According to the automobile door open end display device of the present invention configured as described above, the display device can be easily attached along the complicated curved surface of the corner portion at the door open end, and the exterior from the rear For the approaching person, it is possible to clearly display the door opening end and to ensure water resistance.

  In addition, in the case of a sliding door, it is possible to display the door end not only for an external approaching person from the rear but also for an external approaching person from the front.

  Hereinafter, an automobile door open end display device according to the present invention will be described in detail with reference to the accompanying drawings.

The flat attachment portion 15a and the attachment surface are adhesive or double-sided adhesive. Can be glued with tape. Then, when the light emitter 1 in which the flat attachment portion 14 is not formed, that is, the cylindrical light emitter 1 is pushed into the clip portion 15b of the attachment member 15, the light emitter 1 is sandwiched by the clip portion 15b and emits light on the attachment surface. It is possible to attach the body 1 by following it. In addition, as a material of the attachment member 15, it is preferable to apply a transparent material that is harder than the soft transparent covering body 13 and does not block the light emitted from the light emitter 1. The number of attachment members 15 used when attaching one light emitter 1 can be appropriately selected according to the shape of the attachment surface to which the light emitter 1 is attached.
