Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle auxiliary warning light mounted on a rear glass of a vehicle.

[0002]

[Prior art]

 Conventionally, in a vehicle such as an automobile, as a method of urging a vehicle behind to be warned when operating a brake, moving backward, or changing a traveling direction, it is usual to turn on a brake lamp or a backward light located above a bumper. Is.

However, in the case of a brake lamp or the like located above a normal bumper, when the snow falls, the brake lamp or the like is hidden by the snow and cannot be seen by a vehicle behind, and from a driver with a high seat such as a truck or a bus. It is difficult to determine the lighting display of the brake lamp of the front passenger car traveling in close proximity, and the brake operation state of the front passenger car is clearly discriminated because the vehicle width lamp lights at night. It was difficult to do so, so there was a safety issue.

In order to solve such a problem, a brake lamp in which light emitters are arranged in a row in a substantially horizontal direction at a relatively high position in or around a rear glass surface has been proposed and put into practical use (hereinafter , This is called an auxiliary warning light). Such an auxiliary warning light has the advantage that the light emitting part, which is a warning light, can be placed at a relatively high position, and thus not only has the advantage that it can be easily seen from the vehicle behind, but also that the light emitting part is hidden in the snow during snowfall. It is very useful because it has no advantages and is highly safe.

[0005] Since such an auxiliary warning light is installed in advance on the rear glass, it is not necessary to design an auxiliary warning light for each vehicle type, and a common auxiliary warning light can be used for many vehicle types. it can.

However, since it is necessary to adjust the irradiation direction of the light from the auxiliary warning light up and down according to the vehicle model, it is necessary to mount the auxiliary warning light on the rear glass. Even if there is no hindrance to power supply, power is supplied to the auxiliary warning light by connecting a flexible cord, etc., directly from the power supply section to the wiring or the auxiliary warning light section with a connector. These members that supply power to the lamp are collectively called the power supply member.)

If such a power feeding member is projected and left exposed in the vehicle, it not only looks bad, but also causes damage such as being accidentally caught by a person. It has been proposed that the cover be covered with a cover and that the cover be screwed to a metal member that is adhesively fixed to glass to prevent the power feeding member from protruding and being exposed in the vehicle.

[0008]

[Problems to be solved by the device]

 Generally, most of the materials used for the cover that covers the power supply member exposed inside the vehicle and the case that covers the light-emitting body are made of synthetic resin such as acrylic, polycarbonate, oriolefin, polypropylene, etc. The coefficient of thermal expansion differs from that of glass by a factor of 10 or more.

The temperature inside the vehicle may change by 50 ° C. or more in some cases, and the difference in expansion and contraction between the rear glass and the synthetic resin cover is 1 mm or more due to the difference in the coefficient of thermal expansion. Such a difference in expansion and contraction causes excessive force to the fixing metal fitting adhered to the rear glass and the cover screwed to the rear metal fitting, resulting in damage or peeling of the adhesive joint. Had.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a vehicle warning light that has not been known in the past.

[0011]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and at least one or more luminous bodies that illuminate the rear of a vehicle and a luminous body that is provided at the horizontal ends of the luminous bodies. A warning light mounted on a rear glass of a vehicle, which is equipped with at least a power supply member for supplying electric power, a light emitter case covering the light emitter, and a cover connected to an end of the light emitter case to cover the power supply member. In an auxiliary warning light in which a cover is attached to a fixing metal fitting, the warning light fixing metal fitting has a spring plate that rises substantially vertically from the rear glass surface and is located at the horizontal end portion of the luminous body. The cover has a fitting protrusion provided on the inner side thereof, which is fitted and fixed to a spring plate of the warning light fixing bracket and attached to the rear glass. Provide a lantern Than it is.

[0012]

[Action]

 According to the present invention, since the cover of the auxiliary warning light is fixed by mechanical attachment by fitting the spring plate attached to the rear glass and the cover, it is firmly fixed in the direction perpendicular to the rear glass. However, since it has a structure that can slide freely in the horizontal direction, it is possible to absorb the difference in expansion and contraction between the rear glass and the cover made of synthetic resin, and it is possible to achieve secure fixing.

Further, according to the present invention, since the wiring and the power supply terminal are hidden by the case while being securely fixed, the vehicle is prevented from being accidentally caught by a person and has a stronger strength. Can be used as a warning light.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of an essential part showing an example of the auxiliary warning lamp of the present invention, and FIG. 2 is a cross-sectional view of the essential part seen from above. A light emitting body 20 composed of a plurality of LEDs arranged in parallel in the horizontal direction is attached to a printed circuit board 12, and the printed circuit board 12 has a light emitting body holding member 11 connected to both ends thereof. Further, the luminous body 20 is inserted and covered in the cylinder of the cylindrical luminous body case 10.

As a power feeding member, the printed circuit board 12 communicates with the light emitting body 20, and the lead wire 7 is connected to the power feeding terminal 3 via the connection terminal 6. The power supply terminal 3 is provided at a horizontal end portion of the light emitting body 20, and is connected to a conductive wire 4 that supplies electric power from the vehicle side to the light emitting body 20.

A warning light fixing member 14 is adhered to the rear glass 1 with an adhesive such as polyurethane, and the fixing member 14 has a spring plate 13 which stands up substantially perpendicular to the rear glass 1.

The power supply terminal 3 and the lead wire 7 are hidden by a cover 5 so as not to project and be exposed in the vehicle. The cover 5 is provided with projections 9 on both ends of the case 10 which covers the light emitting body 20. The light emitting body holding member 11 is fixed to this holding portion 18, and the light emitting body 20 is fixed to the rear glass. It

Further, the cover 5 is fixed in a substantially vertical direction with respect to the rear glass 1 by fitting the fitting protrusion 8 of the cover 5 to the spring plate 13 of the warning light fixing metal fitting 14, and the longitudinal direction of the light emitting case 10 1. The direction is slidable. Further, in the direction which is horizontal to the rear glass 1 and perpendicular to the light emitter case 10, the elasticity of the spring plate absorbs the positional deviation with respect to this direction.

FIG. 3 is a schematic perspective view showing a cover of the auxiliary warning light of the present invention, FIG. 4 is a plan view thereof, and FIG. 5 is a sectional view taken along line A-A ′ of FIG. The cover 5 for concealing the lead wire and the power supply terminal provided at the end of the light-emitting body has a fitting projection 8 on the inside thereof, which is fitted to the spring plate of the warning light fixing metal fitting mounted on the rear glass. In addition, it further has a holding portion 18 for fixing the luminous body holding member connected to the end portion of the luminous body. Further, at the end of the cover 5 that comes into contact with the case that covers the light-emitting body, there are provided projections 9, 16 and 17 that engage with this case.

FIG. 6 is a schematic perspective view showing a warning light fixture of the auxiliary warning light of the present invention, FIG. 7 is a side view thereof, and FIG. 8 is a front view thereof. The warning light fixing member 14 has a substantially U-shaped cross section, and a spring plate 13 to which a fitting protrusion of a cover for concealing the power supply member is fitted is provided on the upper portion of the U-shape. The spring plate 13 is provided with a space portion 19, and the space portion 19 and the fitting protrusion of the cover for concealing the power feeding member have substantially the same shape. In this portion, the cover and the warning light fixing metal fitting are provided. Are fitted and fixed.

Further, since the bottom portion of the warning light fixing member 14 is attached to the rear glass, the shape and size of the contact surface depend on various conditions such as the vehicle type and the size of the auxiliary warning light. Therefore, it can be appropriately determined, and is preferably 0. In order to have an area of 5 cm ² or more, and to prevent the size of the cover from becoming too large and hindering the driver's visual field, it is preferable that the area be 6 cm ² or less.

Further, the bottom portion may have a protrusion for ensuring the thickness of the adhesive layer so that the adhesive layer contacts the rear glass with the adhesive layer interposed therebetween. For example, a height of 0.2 to 1.0 mm can be selected to maintain the desired thickness of the adhesive layer.

FIG. 9 is a front view showing an example of the rear glass to which the auxiliary warning light of the present invention is attached. The auxiliary warning light 2 mounted above the vehicle rear glass 1 is connected to the conductive wire 4 provided on the rear glass 1 through the power supply terminals to the auxiliary warning light 2 at both ends. The cover 5 is attached to the end portion of the auxiliary warning light 2 and hides the power supply member such as the power supply terminal. A power supply unit 15 is provided at an inconspicuous part of the end of the rear glass 1, and power is supplied from the power supply unit 15 to the auxiliary warning lamp 2 via the conductive wire 4 and the power supply terminal 3. It

The power supply unit can be partially used as a power source for the anti-fog heat wire of the rear glass, but it may be taken out separately, and the conductive wire may be formed on the rear glass, for example. It is known that the film is made of a conductive film such as Ag paste, but it is not particularly limited to this.

In the present invention, a synthetic resin material is used for the luminous body case and the cover. For example, when the luminous body case is made of polyolefin having a thermal expansion coefficient of 1.17 × 10 ⁻⁴ / ° C. Compared to the rear glass with an expansion rate of 9 × 10 ^-6 / ° C, the difference in expansion and contraction due to the temperature change inside the vehicle, specifically, the auxiliary warning lamp with a total length of 660 mm is 80 ° C. Under the temperature change of 1, the expansion and contraction difference of about 2.9 mm occurs in the longitudinal direction between the two.

This expansion / contraction difference of about 2.9 mm is absorbed by the fitting projection 8 slidingly moving in the space portion 19 of the spring plate 13 in the longitudinal direction of the light emitter, and mounting the cover. The holding power and the mounting force between the warning light fixing bracket and the rear glass are prevented from decreasing.

Further, the difference in the coefficient of thermal expansion causes not only the expansion / contraction difference in the longitudinal direction of the light-emitting body but also the expansion / contraction difference in the direction perpendicular to the light-emitting body. It is absorbed by the elasticity of the spring plate of the metal fitting. From this point, it is preferable that the spring plate of the warning light fixing metal fixture is made of a spring material having an elastic constant of 2 to 25 kg / mm. A 5 mm thick phosphor bronze plate, stainless spring steel, carbon tool steel, etc. are preferably used.

Here, the following cooling / heating cycle test was performed using the auxiliary warning light based on the above drawings. Put the auxiliary warning light attached to the rear glass in the temperature of 90 ° C for 4 hours and then in the temperature of -40 ° C for 1.5 hours for 4 cycles, then in the temperature of 100 ° C for 15.5 hours. After that, the step of placing it in a temperature of −30 ° C. for 7.5 hours was performed for 4 cycles. Further, after being placed in a temperature of −40 ° C. for 4 hours, the transition time is set to a temperature of −40 ° C. to 80 ° C. in 2 hours, placed in this temperature of 80 ° C. for 4 hours, and a transition time is set to 80 ° C. in 2 hours. As a result of continuing the process in which the process of increasing the temperature from ℃ to −40 ° C. as one cycle was continued for 8 weeks, there was no abnormality such as damage to the light-emitting body and separation of the rear glass and the mounting bracket.

Of course, the present invention is not limited to the drawings based on the above-described embodiments. For example, when mounting the warning light fixing bracket on the rear glass, it is adhered by an adhesive such as polyurethane. However, the invention is not limited to this, and it may be mounted by interposing a double-sided tape, or by mechanical means such as perforating the rear glass and screwing.

The light emitting body is not particularly limited as long as it has a light amount sufficient to warn the rear, and an LED, a halogen lamp, a fluorescent display tube or the like is used. At least one of these light emitters is attached to the printed circuit board, but in view of being able to sufficiently warn the rear, it is preferable to arrange a plurality of light emitters in parallel in the horizontal direction of the rear glass, The layout is determined appropriately so that it fits neatly in the case and also has a design effect.

The case that covers the light-emitting body is not particularly limited in its shape as long as it can protect the light-emitting body from external influences, and the case where the light-emitting body and the printed circuit board are uniformly covered in the longitudinal direction. Even if it is cylindrical, it has a shape in which one surface of the cylindrical case in the longitudinal direction is opened so that the light emitter is surrounded by the rear glass and the case, and the opening line is in contact with the rear glass. It may be

The cover that is engaged and fixed to the case to conceal the power feeding member is provided at a portion where the power feeding member is provided, and is fixed to an end portion of the case. When the power feeding member is only at one end of the case, the cover may be engaged and fixed only at one end of the case where the power feeding member is provided, but in consideration of the design effect, the cover is engaged and fixed at both ends of the case. It is preferable.

Further, since the mounting angle of the printed circuit board is changed depending on the vehicle type, the shape of the warning light fixing metal fitting in the present invention is different depending on the mounting angle of the holding member connected to the printed circuit board. Even so, the space for accommodating the holding member can be guaranteed at all angles (see FIG. 7), and the size of the cover can be made as small as possible. A U-shaped cross section is preferable, but the shape is not limited to this.

Further, if the spring plate on the upper part of the warning light fixing metal fitting stands up substantially perpendicular to the rear glass, the elasticity of the spring is in the longitudinal direction of the light emitting body even in the longitudinal direction of the light emitting body. There are no particular restrictions on whether the direction is vertical to the other direction or other directions, but in view of the ease of designing the shape of the fitting protrusion of the cover, the direction perpendicular to the longitudinal direction of the light emitter. It is preferable to have elasticity.

[Effect of device]

 According to the present invention, by fitting and attaching the warning light fixing bracket attached to the rear glass and the cover, even if a difference in thermal expansion occurs between the synthetic resin cover or case and the glass due to environmental temperature change, Auxiliary warning light and warning light fixing metal fittings can be attached without excessive force, eliminating the danger of peeling off the attachment part or damage to the light emitter, lead wires, etc. You get a warning light.

Further, according to the present invention, the cover for covering the power supply terminal, the flexible cord, and the like can cover the power supply terminal, the flexible cord, and the light emitter holding member, so that the irradiation angle of the auxiliary warning light can be changed. By attaching the obtained flexible cord or the luminous body holding member, it is possible to obtain an auxiliary warning lamp that can irradiate in a desired direction according to the vehicle type without changing the luminous body itself.

In particular, when the warning light fixing metal fitting mounted on the rear glass has a U-shaped cross section, a space for the flexible cord and the luminous body holding member can be secured, and the length of the cover can be shortened. can do.
