Description

  The present invention relates to a warning light.

  2. Description of the Related Art Conventionally, a warning light attached to the top of a vehicle that can output light from a light emitting unit such as a light bulb or an LED to the outside is known. In this type of warning light, it is common to connect a harness extending from the inside of the vehicle to a harness existing in the main body of the warning light to perform power supply and signal transmission / reception. For example, in patent document 1, in the structure which mounts a vehicle-mounted warning light to a vehicle with a mounting base, it is comprised so that a code | cord | chord may extend from the hole formed in the base of a vehicle-mounted warning light inside the mounting base. . Patent Document 2 discloses a structure in which a roof is sandwiched between a male coupler and a female coupler, a harness on a vehicle body side and a diffused warning light harness are connected and waterproofed.

Utility Model Registration No. 2554787 No. 4-25774

  In the prior art, it has been difficult to ensure the reliability of the warning light main body. That is, since the warning light main body and the vehicle are manufactured in separate processes, it is necessary to electrically connect the warning light main body and the vehicle in order to start the operation with the warning light mounted on the vehicle. . In Patent Document 1, a cord extends from a hole formed in the base of the in-vehicle warning light to a hole formed in the vehicle. However, as shown in FIG. Since it is not cut | disconnected between the upper parts of a vehicle, it is necessary to connect a code | cord | chord in a warning light main body or a vehicle. Since it is extremely difficult to connect the cord in the vehicle, conventionally, the cord is generally connected in the warning light main body.

  Therefore, in order to connect the cord in the warning light body, it is necessary to disassemble or open and close the warning light body, disassemble the warning light body, or open the outer wall and connect the cord. is there. However, since the warning light body can be used outdoors for a long period of time, it is extremely important that the circuit inside the warning light body is waterproof, and once the work is disassembled or the outer wall is opened If this is done, it will be difficult to ensure the reliability of waterproofing even if the work of assembling the warning light body is performed again. In particular, if the manufacturer of the warning light body is different from the manufacturer of the warning light body, even if the warning light body manufacturer guarantees waterproof performance, when the user disassembles the warning light body, The waterproof performance cannot be guaranteed, and the reliability when operating the warning light main body is lowered.

On the other hand, in Patent Document 2, waterproofing is performed by a coupler, but since the harness is exposed between the coupler and the diffused warning light, the harness can be easily cut. Since a diffused warning light is generally used in an emergency vehicle, reliability is impaired when the harness can be easily cut by mischief or the like.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of connecting harnesses on the user side without impairing reliability.

  In order to achieve the above-mentioned object, a main body including a light emitting portion that outputs light to the outside and a connecting portion connected between the main body and the vehicle body, the main body being concealed by connecting the connecting portions The body-side concealing part, which is the part of the body, has a body-side opening that opens from the inside of the body to the outside, and an intrusion hole that allows water to enter the inside of the body is formed in parts other than the body-side concealing part In addition, an opening / closing part that can be opened and closed is formed on the outer wall of the connecting part, and on the inside of the opening / closing part, on the vehicle body that is concealed by connecting the connecting part with the main body side harness that extends from the main body side opening. It constitutes a warning light to which a vehicle body side harness extending from a vehicle body side opening formed in the vehicle body side concealing portion, which is a part, is connected.

  That is, in the structure which connects a main body to a vehicle body via a connection part, a main body side harness and a vehicle body side harness are connected inside a connection part. And in the main body, since the intrusion hole which infiltrates water is not formed in the inside, the waterproof performance of the main body is ensured. Moreover, since the opening / closing part is formed in the connecting part, it is possible to perform an operation of connecting the connectors existing at the tip of the harness with the opening / closing part opened. Therefore, it is possible to connect the harnesses on the user side without impairing the waterproof reliability in the main body.

  Here, the main body includes a light emitting unit, and if the light emitting unit can output light representing a predetermined meaning to the surroundings of the warning light, such as being in an emergency or working. Good. The light source of the light emitting unit is not particularly limited, and the light source can be configured by a light emitting element such as an LED or a light bulb such as a halogen lamp. Of course, the light emitting unit may be configured as a rotating lamp that rotates the output direction of light from the light source, or may be configured to adjust the output light by changing the intensity of the output light from the light source.

  In addition, the main body has a main body side concealed portion with a main body side opening, and other parts are not provided with intrusion holes that allow water to enter inside. What is necessary is just to be comprised so that it may not enter. Of course, the presence or absence of an intrusion hole is determined when the main body is assembled, and even if holes such as screw holes that are not opened after the main body is assembled are formed in the main body, If water does not enter, the hole is not an intrusion hole.

  In order to configure so that the intrusion hole for allowing water to enter the inside of the main body is not formed in a part other than the main body side concealing part, various configurations can be adopted, for example, in a part other than the main body side concealing part In addition, it may be configured such that a hole that opens to the outside is not formed, or when a main body is configured by combining a plurality of members, a configuration in which a seal member is interposed in a gap between the members may be employed. .

  The main body-side concealing portion is a portion that is not exposed to the outside of the main body when the connecting portion is connected to the main body. Therefore, when the connecting portion is connected to the main body, the main body side opening formed in the main body side concealing portion is not exposed to the outside of the main body and the connecting portion due to the presence of the connecting portion.

  The connecting portion is configured so that the main body can be attached to the vehicle body via the connecting portion by being connected between the main body and the vehicle body. Further, since the main body side opening and the vehicle body side opening are formed in a portion concealed by the connecting portion, the connecting portion functions as a member that does not expose the main body side opening and the vehicle body side opening to the outside. . For this reason, a connection part has a function which waterproofs a main body side opening part and a vehicle body side opening part. Of course, it is preferable that the portion where the connecting portion and the main body come into contact with each other is waterproofed by a seal member or the like.

  Furthermore, the opening / closing part formed in the connecting part only needs to be configured to perform an operation of connecting the main body side harness and the vehicle body side harness inside the opening / closing part. Therefore, the opening / closing part may have an opening that allows the connector, which is the tip of the harness, to be pulled out to the outside of the connecting part to connect the connectors, and the connectors are connected inside the connecting part. You may have the opening which can do. Various mechanisms can be adopted as the mechanism for opening and closing, and the opening and closing unit may be detachable, or the outer wall may be opened and closed using a hinge or the like.

  The connecting part has an opening / closing part, and the user of the warning light can open and close the opening / closing part and connect the harness connectors in the process of attaching the main body and the connecting part to the vehicle body. Is possible. Therefore, the waterproof performance in the opening / closing section is relatively lower than that in the body other than the opening on the main body side compared to being able to guarantee the waterproof performance, but of course the opening / closing section is also closed in the opening / closing section. It is preferable to be waterproofed. Further, in the main body, it is not necessary to disassemble the main body in a scene where the main body is attached to the vehicle body via the connecting portion or a harness connector is connected. Therefore, the waterproof performance of the main body can be configured to be higher than that of the connecting portion. For example, it is possible to adopt a configuration that relatively enhances the performance of seal members and screws that are arranged so as to be interposed between the components that make up the main body, and specifications required for assembly (such as the number of rotations of the screws). is there.

  Furthermore, a speaker horn is provided inside the connecting portion, a speaker driver is provided inside the main body, and a sound conducting portion that connects the sound output port of the speaker driver and the sound input port of the speaker horn by a cavity. May be provided. That is, the connecting portion is configured to have a function as a speaker horn in addition to a function of connecting the main body and the vehicle body. In this configuration, since the space in which the waterproof performance is ensured is inside the main body, a speaker driver that can include an electric circuit for driving the speaker is provided inside the main body. In this case, since the speaker driver and the speaker horn are arranged at positions apart from each other, a sound conducting portion is formed inside the main body in order to transmit the output sound from the speaker driver to the speaker horn.

  The speaker horn adjusts the directivity of the sound input from the input port and the state of resonance, and adjusts the sound so that the sound of the desired frequency (for example, siren sound) is sufficiently loud at the desired position. If you can. Therefore, for example, it is possible to assume a configuration such as a reflex horn speaker that has a sound transmission path in which the traveling direction of the sound input from the input port changes a plurality of times and the cross-sectional area gradually increases as the sound progresses. It is.

  The speaker driver is a device for outputting sound such as a siren from the output port of the speaker driver, and includes, for example, a power source, an amplifier, a diaphragm (diaphragm), a magnet, a voice coil, a storage unit for output sound data, and the like. Can be assumed.

  The sound conducting unit may be a part that connects the sound output port of the speaker driver and the sound input port of the speaker horn with a cavity. That is, when the speaker driver output port and the speaker horn input port are connected by a hollow tube having an arbitrary shape, the sound output from the speaker driver output port is transmitted through the cavity inside the tube. And what is necessary is just to be comprised so that the input port of a speaker horn may be reached.

  The sound conducting unit may be a part of the main body, and the tube constituting the sound conducting unit may be configured integrally with a member having another function or may be configured separately. As an example of the former, for example, it is possible to assume an example in which the main body includes a support unit that supports the light emitting unit, the speaker driver, and the speaker horn, and the support unit and the sound conducting unit are integrally configured.

  In the above configuration, the output sound used in the vehicle is assumed to be a relatively loud sound such as a siren. The speaker horn required in this case occupies about 1/3 of the width of the main body and is vertical. The structure is relatively large, such as occupying about several centimeters in the direction (for example, the width of the main body is 110 cm, the width of the speaker horn is 35 cm, etc.). Therefore, it is easy to configure the connecting portion including the speaker horn so that the harness connector can be accommodated inside the opening / closing portion, and the speaker horn and the harness connector accommodating portion are provided in the connecting portion. Therefore, it is not necessary to provide a dedicated space for the connector of the harness, and the warning light can have a simple configuration.

  Further, the connecting portion may include a connector housing chamber that houses the connector of the main body side harness and the connector of the vehicle body side harness and at least a part of which constitutes an opening / closing portion. According to this structure, even if the opening / closing part is opened / closed, the connector housing chamber is exposed at the connecting part, but other parts (speaker horn, etc.) are not exposed. Therefore, if waterproofing is performed so as to prevent water from entering from the connector housing chamber to other parts of the connecting part, the part where water can enter can be limited to a narrow range by opening and closing the opening and closing part. Of course, even in this case, it is preferable to waterproof so as to prevent water from entering the connector housing chamber by closing the opening / closing part.

In FIG. 1B and FIG. 2A, the main body 20 and the connecting portion 30 are disassembled, and the main body 20 is further disassembled. Show. In FIG. 3, the main body 20 and the connection part 30 are further disassembled. 1B and 3 are exploded perspective views as viewed from above, and FIG. 2A is an exploded perspective view as viewed from below. The main body 20 includes a cover 20a and a support portion 20b, and some parts (light emitting portions and the like) are omitted.

  The cover 20a is formed of a resin having a transparent chromatic color (yellow, yellow red, red, blue, etc.), and can accommodate the light emitting part inside, and the light output from the light emitting part can be visually recognized from the outside. It is. Further, as shown in FIG. 3, the cover 20a is composed of a plurality of parts that can be disassembled in the x-axis direction, and is slide-inserted into a rail 20i (described later) of the support part 20b on the inner wall below each part. A possible insertion part 20j is formed.

  The support part 20b is a hollow member constituted by a thin plate made of aluminum, and its outer shape is a substantially rectangular parallelepiped. FIG. 2B is an enlarged view of the end portion in the x-axis direction of the support portion 20b. In the support portion 20b, the end portion in the y-axis direction (the end portion in the front-rear direction of the vehicle) is parallel to the x-axis direction. A rail 20i is formed extending in the direction. As shown in FIG. 2B, the rail 20i is configured such that the end portion in the y-axis direction of the support portion 20b is bent downward, and the insertion portion 20j of the cover 20a can be slid and inserted in the x-axis direction. .

  Furthermore, plate-like members 20f can be attached to both ends of the support portion 20b in the x-axis direction. That is, two screw holes are formed in the plate-like member 20f, and two screw holes are formed at corresponding positions on both ends in the x-axis direction of the support portion 20b. Further, the parts of the cover 20a attached to both ends in the x-axis direction are formed with recesses 20k in which screw holes for performing the work of fastening the cover 20a and the support part 20b with the screws are formed in the lower part. .

  Accordingly, the insertion part 20j of each part of the cover 20a is slid into the rail 20i of the support part 20b in a predetermined order, and finally the plate-like members 20f are temporarily arranged at both ends in the x-axis direction of the support part 20b. It is possible to support the cover 20a with the support portion 20b by slidingly inserting the insert portions 20j of the parts of the cover 20a attached to both ends in the x-axis direction into the rail 20i of the support portion 20b and fastening with screws. It is. Thus, in a state where the cover 20a is supported by the support portion 20b (a state where the cover 20a is attached to the support portion 20b), the main body 20 is substantially a rectangular parallelepiped, and the support portion 20b is a bottom surface (a plane parallel to the xy plane). The lower surface).

  In the present embodiment, a seal member is interposed between both ends of the support portion 20b and the plate-like member 20f, and a seal member is provided between the rail 20i of the support portion 20b and the insertion portion 20j of the cover 20a. Inserted. Therefore, the main body 20 is waterproofed by these sealing members.

  Further, in the support portion 20b, a hollow sound path 20c extending in a direction parallel to the x-axis direction is formed at the center in the y-axis direction. That is, as shown in FIG. 2B, in the support portion 20b, the sound path 20c having a rectangular cross section perpendicular to the yz plane extends in a direction parallel to the x-axis direction and penetrates the support portion 20b. Yes. Therefore, the sound path 20c has a constant cross-sectional shape in the direction perpendicular to the zy plane over the entire length in the x-axis direction and a constant cross-sectional area over the entire length in the x-axis direction.

  As shown in FIG. 2B, two rails 20e are formed on the upper surface of the support portion 20b in a direction parallel to the x-axis direction. A nut is inserted into the rail 20e and the position of the nut is set at an arbitrary position. Can be moved to. The nut is inserted with the screw hole directed toward the opening of the rail 20e (upward), and the screw is inserted into the nut from the upper side, thereby tightening the screw to the nut at an arbitrary position.

  A speaker driver 20d is supported at the center of the upper surface of the support portion 20b as shown in FIG. 1B. That is, the speaker driver 20d is configured by inserting a circular portion having a gradually decreasing diameter into the rectangular parallelepiped portion 20d1, and the rectangular parallelepiped portion 20d1 has screw holes formed at a plurality of locations. Then, by inserting a screw into the screw hole and tightening the nut and the screw inserted into the rail 20e, the speaker driver 20d is supported at the center of the upper surface of the support portion 20b.

  The speaker driver 20d is a device including a diaphragm (diaphragm), a magnet, a voice coil, and the like, and an output port (not shown) formed on the lower surface of the rectangular parallelepiped portion 20d1 is a sound output by vibrating the diaphragm. Can be output. A driver side opening corresponding to the output port of the speaker driver 20d is formed at the center of the upper surface of the support portion 20b, and the driver side opening is connected to the sound path 20c. The speaker driver 20d is attached to the support portion 20b with a seal member 20d2 sandwiched between the output port of the speaker driver 20d and the driver side opening. Therefore, the sound output from the output port of the speaker driver 20d is transmitted into the sound path 20c without leaking outside the support portion 20b.

  The connection part 30 is connected to the lower surface of the support part 20b. That is, on the lower surface of the support portion 20b, two rails 20g are formed in a direction parallel to the x-axis direction as shown in FIG. 2B. A nut is inserted into the rail 20g and the position of the nut is arbitrarily set. It can be moved to the position. Further, the nut is inserted with the screw hole directed toward the opening of the rail 20g (downward), and the screw is inserted into the nut from the lower side, thereby tightening the screw to the nut at an arbitrary position. Can do.

  The connecting unit 30 includes a speaker horn S (see FIG. 3) that adjusts the directivity and resonance state of the sound input from the input port and adjusts the sound so that the siren sound is sufficiently loud at a desired position.

That is, in the present embodiment, the speaker horn S that changes the sound traveling direction twice while gradually increasing the cross-sectional area of the sound path from the sound input port is formed by the rib of the lower surface portion 30d. Furthermore, four bosses B for connecting the connecting portion 30 to the main body 20 are formed. Furthermore, a wall surface for forming the connector housing chamber H as a rear portion of the connecting portion 30 is formed, and a connector insertion hole 30r is formed in a portion constituting the lower wall surface of the connector housing chamber H. (See FIG. 2A).

  The upper surface portion 30g is formed of a thin plate-like member, and a sound is generated at a position corresponding to the end portion (sound input end) of the hole 30a and the speaker horn S at a position corresponding to the boss B formed on the lower surface portion 30d. The connector insertion hole 30m is formed at a position corresponding to the input port 30b and the upper surface of the connector housing chamber H. Therefore, by aligning the upper surface portion 30g with the lower surface portion 30d, the ribs on the lower surface portion 30d constituting the speaker horn S and the ribs on the lower surface portion 30d constituting the connector housing chamber H are closed. As a result, the speaker horn S is opened at the front and the input port 30b, and the connector housing chamber H is opened at the rear and the connector insertion holes 30m and 30r.

  The upper surface portion 30g is further bent downward at four locations, the front end and the rear end, and has screw holes. Of these screw holes, two places near the end in the left-right direction are small, and two places near the center are large. The smaller screw hole 30n is a screw hole for connecting the open / close portions 30e and 30f, and the larger screw hole 30o is a screw hole for connecting the bracket 30i.

  That is, the opening / closing portions 30e and 30f are members having a size covering the front and rear of the lower surface portion 30d, and include fins extending in the left-right direction and the up-down direction. Further, screw holes (in FIG. 3, the screw hole of the opening / closing part 30f is expressed as Hs) are formed at positions corresponding to the screw holes 30n at the left and right ends of the opening / closing parts 30e, 30f. Therefore, the open / close portions 30e and 30f can be connected to the lower surface portion 30d with screws in a state where the screw holes Hs are aligned with the screw holes 30n. In a state in which the opening / closing portions 30e, 30f are connected to the front and rear of the lower surface portion 30d, as shown in FIG. 1B, the speaker horn S opens forward through the fins of the opening / closing portion 30e and at the input port 30b. It will be in the state opened upwards. The connector housing chamber H is closed by the opening / closing part 30f and does not open rearward, but opens upward through the connector insertion hole 30m and opens downward through the connector insertion hole 30r.

  As described above, the connecting portion 30 is attached to the support portion 20b in a state where the upper surface portion 30g and the opening / closing portions 30e and 30f are attached to the lower surface portion 30d. In other words, the upper surface 30g of the connecting portion 30 has four holes 30a for passing through the screws, and the lower surface 30d of the connecting portion 30 has four bosses B for passing the screws (see FIG. Hb shown in 2A). Therefore, as shown by a dashed line arrow in FIG. 2A, a screw is inserted from below into the hole Hb below the boss B, and the nut inserted into the rail 20g and the screw are tightened to thereby connect the connecting portion 30. Is supported at both ends of the lower surface of the support portion 20b in the x-axis direction.

  In the present embodiment, the position where the connecting portion 30 is attached to the support portion 20b can be changed in the x-axis direction. That is, on the lower surface of the support portion 20b, body-side openings 20h are formed at two locations corresponding to the attachment position of the connecting portion 30. The main body side opening 20h is long in the x-axis direction, the edge in the longitudinal direction is a straight line parallel to the x-axis direction, and the edges are semicircular at both ends in the x-axis direction. Therefore, the attachment position of the connecting portion 30 can be changed within a range in which the input port 30b formed in the upper surface portion of the connecting portion 30 is connected to the sound path 20c through the main body side opening 20h.

  Furthermore, the connection part 30 is connected with the upper surface of a vehicle body by the bracket 30i below. That is, the bracket 30i has a shape in which both ends of an elongated plate-like member are bent at a right angle, each of which has screw holes 30j at both ends, and two screws are provided between the bent portions. A hole 30k is provided. Further, the pedestal portion 30h is a cylindrical member having a substantially rectangular circumference, and the vertical height of the circumference is configured to gradually change according to the shape of the lower surface of the connecting portion 30 and the upper surface of the vehicle body. Has been.

  The lower surface portion 30d of the connecting portion 30 is formed with a total of four holes 30p into which both ends of the bracket 30i can be inserted, and the pedestal portion 30h has both ends of the bracket 30i at two locations on the rib extending inward. A hole 30q into which can be inserted is formed. Therefore, both ends of the bracket 30i are inserted into the holes 30q of the pedestal portion 30h, and further, both ends of the bracket 30i are inserted into the holes 30p of the lower surface portion 30d, and the screw holes 30j at both ends of the bracket 30i and the upper surface portion of the connecting portion 30 The 30 g screw hole 30o can be faced to each other. Therefore, in a state in which the pedestal portion 30h is interposed between the bracket 30i and the connecting portion 30 by inserting and fastening screws into the screw holes 30j and 30o with the opening / closing portions 30e and 30f removed. The bracket 30 i can be attached to the connecting portion 30.

  Accordingly, the bracket 30i is attached to the upper surface of the vehicle body by the screw hole 30k of the bracket 30i, and the pedestal portion 30h is interposed on the lower surface of the connecting portion 30 in a state where the connecting portion 30 and the main body 20 are connected. By connecting 30, the main body 20 and the connecting portion 30 can be attached above the vehicle body. The pedestal portion 30h is a flexible resin, and the circumferential height changes according to the shape of the lower surface portion 30d of the connecting portion 30 and the upper surface of the vehicle body. It functions as a sealing member for waterproofing 30. Moreover, in the connection part 30, a sealing member is arrange | positioned in the site | part where members contact, for example, the site | part which the upper surface part 30g and the lower surface part 30d contact, and waterproofing is made | formed.

Since a seal member is interposed between the upper surface portion 30g and the support portion 20b, water can be prevented from entering the main body side openings 20m and 20h. Moreover, since the grommet 20m1 is attached to the upper part of the main body side opening 20m, the grommet 20m1 also prevents water from entering the main body 20. Furthermore, since the grommet 30r1 is attached to the insertion hole 30r of the connecting portion 30, the intrusion of water into the main body 20 is also prevented by the grommet 30r1.

  According to this configuration, a user does not remove a sealing member related to waterproofing in the main body 20 (such as a sealing member between the cover 20a and the support portion 20b or a sealing member between the upper surface portion 30g and the support portion 20b). The connection work between the connectors 41a and 41b can be performed. In addition, no opening other than the opening on the main body side is formed on the outer surface of the main body 20, and an intrusion hole for allowing water to enter the inside of the main body 20 into a portion other than the concealing portion Ph on the outer surface of the main body 20 Is not formed. Accordingly, after the work of attaching the sealing member related to the waterproofing in the main body 20 is performed by a waterproof performance guarantor (manufacturer of the warning light, etc.) and the warning light is delivered to the user, the waterproofing in the main body 20 is performed. It is possible to perform the connection work between the connectors 41a and 41b without performing the work of removing the seal member related to the user, the work of removing the main body 20 from the connecting portion 30, the work of disassembling the cover 20a of the main body 20, etc. . For this reason, it is possible to continue the operation of the warning light in a state where the initial waterproof performance that the waterproof performance of the main body 20 is higher than that of the connecting portion 30 is guaranteed.
