Detailed Description

Hereinafter, a specific embodiment of the present utility model will be described with reference to the drawings. The embodiments are not limited to the utility model, but are exemplified, and all the features and combinations thereof described in the embodiments are not necessarily essential to the utility model. In the following description of the embodiment and the modification, the same reference numerals are given to the same components, and overlapping descriptions are appropriately omitted. In each drawing, the dimensions and ratios do not reflect actual numerical values, and the configuration is schematically represented.

(first embodiment)

Fig. 1 is a perspective view of a vehicle lamp 1 according to a first embodiment. Fig. 2 is a front view showing a schematic configuration of the vehicle lamp 1.

As shown in fig. 1 and 2, the vehicle lamp 1 is a headlight, and is mounted on the left and right sides of the front portion of the vehicle. The vehicle lamp 1 includes a lamp body 2 and a globe 4 as a lamp housing.

The lamp body 2 is a frame body having a front opening, and the globe 4 is attached to the opening, thereby forming a lamp room S inside. The globe 4 is a so-called cover, and is a substantially transparent lens formed of a light-transmitting resin such as polycarbonate, for example.

In the divided lamp room S, a lamp unit Hi for high beam and a lamp unit Lo for low beam are accommodated. The high beam lamp unit Hi and the low beam lamp unit Lo are optical units configured to radiate light emitted from a light source to the front and to form high beam light distribution and low beam light distribution in the front of the vehicle. The lamp units Hi and Lo are not limited in type, and conventionally known lamp units, such as reflection type lamp units and projection type lamp units, are used. As the light source for each of the lamp units Lo and Hi, a light emitting element that does not generate heat, such as an LED (Light Emitting Diode ), an LD (Laser Diode), an EL (Electro Luminescence), or an electroluminescent element, is used.

A heat generating member 6 for generating heat by supplying electricity to the hot wire circuit pattern is laid on the inner surface of the globe 4. The heat generating member 6 is formed in a linear shape and is provided on substantially the entire inner surface of the globe 4 in a predetermined wiring pattern. Snow and ice adhering to the outer surface of the globe 4 are melted by heat generated by the heat generating member 6, and fog generated inside and outside is eliminated, thereby ensuring proper light distribution of the lamp units Hi and Lo. The snow melting function of the vehicle lamp 1 is realized by the heat generating member 6.

For example, a resistance heating wire is used as the heat generating member 6, and a desired circuit pattern is provided on the inner surface of the globe 4. The resistance heating wire is composed of a member having relatively low electric conductivity such as tungsten, molybdenum, nickel chromium, or the like. By supplying power to the resistance heating wire, the resistance heating wire is heated by the resistance, and thereby the resistance heating wire rises to a temperature at which snow can be melted. Since the heat generating member 6 is formed to be slender, the decrease in transmittance of the globe 4 is suppressed within the allowable range. In the present embodiment, the linear heat generating member 6 is laid in a wiring pattern that is continuous in a substantially parallel manner while meandering in a zigzag manner in the left-right direction. The wiring pattern of the heat generating member 6 is not limited to this, and may be mainly in front of the lamp units Hi and Lo and may be laid on the light transmitting portion of the globe 4.

Electrical contacts 20, 20 are formed at the end portions that become the start and end points of the heat generating member 6. The electric contacts 20 and 20 are power supply ports of the heat generating member 6, and power is supplied to the heat generating member 6 from a vehicle battery connected via the electric contact 20.

In the vehicle lamp 1, the power supply portion 30 is provided inside the lamp body 2 as a mechanism electrically connected to the electric contact 20 for supplying power to the heat generating member 6. The power supply unit 30 is connected to the vehicle battery, and the connection terminal of the power supply unit 30 is in contact with the electric contact 20 and is electrically connected to the electric contacts 20 and 20, so that power is supplied from the vehicle battery to the heat generating member 6.

(mounting of the lampshade and the Lamp body 2)

Fig. 3 is a view showing the vehicle lamp 1 in a state where the globe 4 is removed (a state where the globe 4 and the lamp body 2 are opened). Internal mechanisms of the lamp units Hi, lo, etc. are omitted. Fig. 4 is a cross-sectional view taken along line IV-IV of fig. 2. Fig. 5 is an exploded perspective view of the vehicle lamp 1. The power supply section 30 is mainly shown. Fig. 6 is an exploded perspective view of the vehicle lamp 1. The lamp body 2 and the lamp housing 4 are mainly shown.

As shown in fig. 3 to 6, seal legs 4a are formed at the peripheral edge portion of the back surface side of the globe 4. Inside the surrounding seal legs 4a, three first bosses 4b are provided, each of which is inscribed in the seal leg 4a and is equally separated from the upper side and the lower side. The first boss 4b is an attachment portion for attaching the lamp housing 4 to the lamp body 2.

A seal groove 2a engaged with the seal leg 4a is provided around the peripheral edge of the front surface opening of the lamp body 2. The seal groove 2a is provided with an engagement bulge 2b which engages with a first boss 4b inscribed in the seal leg 4a. The engagement bulge portion 2b is provided corresponding to the first boss 4b formed on the inner side of the seal leg 4a, and is formed by bulging a part of the inner peripheral surface of the seal groove 2a toward the inner side of the lamp chamber S.

Further, on the back surface side of the engagement bulge portion 2b, a lamp body concave portion 2c in which the outer wall of the lamp body 2 is concave toward the lamp chamber S side extends linearly from the front surface toward the back surface continuously from the engagement bulge portion 2b bulged toward the inside of the lamp chamber S. The lamp body recess 2c is formed so that the first fixing member 5 for the lamp body, such as a tapping screw fastened to the first boss 4b, and the assembly tool for the first fixing member 5 are inserted therethrough, and is recessed in a frame body having a substantially constant wall thickness, so that the formation surface of the lamp body recess 2c on the lamp chamber S side is a portion of the peripheral wall constituting the lamp chamber S and bulges toward the inside of the lamp chamber S.

As shown in fig. 6, the lamp housing 4 is assembled to the lamp body 2 by disposing the lamp housing 4 to face the opening of the lamp body 2, engaging the seal leg 4a with the seal groove 2a, fitting the first boss 4b into the engagement bulge 2b, and screwing the first fixing member 5 into the first boss 4b from the back surface. The back surface of the engagement bulge portion 2b (the bottom surface of the seal groove 2 a) facing the hole of the first boss 4b is formed thin, and the first fixing member 5 is screwed into and inserted through the thin portion, and is fastened to the first boss 4b.

In the present embodiment, the boss structure is used for mounting the lamp housing 4 and the lamp body 2, and the first boss 4b is provided as the mounting portion in the lamp housing 4 and the engagement bulge 2b is provided as the mounting portion in the lamp body 2, respectively, and screw fastening is performed.

(Power supply portion 30)

As shown in fig. 3, the power supply portion 30 is provided at a central lower portion in the vicinity of the opening of the lamp body 2. Specifically, the power supply portion 30 is attached to the lamp body 2 by being engaged in the vicinity of the engagement bulge portion 2b provided in the center of the lower portion of one of the six engagement bulge portions 2b provided in the opening portion of the lamp body 2 so as to surround the engagement bulge portion 2b.

The electrical contact 20 of the globe 4 is provided corresponding to the power supply unit 30, and is provided in the vicinity of the first boss 4b provided at the central lower portion of the globe 4, which serves as a mounting unit, in the same manner as the power supply unit 30. By providing the power feeding portion 30 and the electric contact 20 in the vicinity of the engagement bulge portion 2b and the first boss 4b, which are the attachment portions of the lamp housing 4 and the lamp body 2, the power feeding portion 30 and the electric contact 20 can be arranged with the engagement bulge portion 2b and the first boss 4b as marks, and the arrangement deviation of the power feeding portion 30 and the electric contact 20 can be suppressed. In addition, since there is little error even after the lamp housing 4 is mounted to the lamp body 2, the mounting offset of the power supply portion 30 and the electrical contact 20, which are separately disposed, is suppressed. The power feeding portion 30 and the electrical contact 20 may be provided in the vicinity of any other first boss 4b and the engagement bulge portion 2b, not limited to the first boss 4b and the engagement bulge portion 2b provided in the central lower portion.

As shown in fig. 5, the power supply unit 30 includes a pair of terminals 31, a connector 32, and a board 39 to which the terminals are attached, and the power supply unit 30 is attached to the lamp body 2 via a bracket 40.

The terminal 31 is a leaf spring terminal formed by bending a thin metal plate in an S shape so as to be elastically deformable. The pair of terminals 31, 31 are disposed so as to face the electrical contacts 20, and are mounted on the surface of the substrate 39 in a direction that is elastically deformable and faces the electrical contacts 20. The terminal 31 is not limited to a leaf spring terminal, and a flexible rod-shaped terminal such as a probe or a spring connector is used.

The connector 32 is mounted on the back side of the substrate 39. The connector 32 is electrically coupled to the terminal 31, and a lead terminal connected to a vehicle battery, not shown, is fitted to the connector 32.

The bracket 40 has a hollow rectangular parallelepiped outer shape with a rear opening, and flange portions 40g are provided on the left and right sides of the rear opening. The substrate 39 is fixed to the front surface 40a of the bracket 40 with the surface on which the pair of terminals 31, 31 are mounted facing the opening of the lamp body 2, and is indirectly attached to the lamp body 2 via the bracket 40. The second boss 40d for fastening the board 39 is exposed to the front surface 40a on the central rear surface side of the front surface 40a of the bracket 40 to form a boss hole, and the second fixing member 35 is inserted into the through hole 39a provided in the center of the board 39 and fastened to the second boss 40d, so that the power feeding portion 30 based on the board 39 is fixed to the bracket 40. The front surface 40a is also provided with a frame 40j corresponding to the outer shape of the rectangular flat plate-like substrate 39, and a cutout 40f through which the connector 32 mounted on the back surface of the substrate 39 passes, and the substrate 39 is engaged with the front surface 40a of the bracket 40 to be stably disposed.

Since the bracket 40 and the substrate 39 fixed to the front surface 40a are disposed in the vicinity of the engagement bulge portion 2b, a notch portion 39c and a notch portion 40c are formed in the lower center of the substrate 39 and the bracket 40, respectively, so as to avoid interference with the engagement bulge portion 2b and engage with the engagement bulge portion 2b.

A hollow rectangular parallelepiped convex portion 2e protruding from the bottom surface of the lamp chamber S is formed in the lamp chamber S of the lamp body 2 as a mounting portion of the bracket 40. The hollow portion of the protruding portion 2e is exposed to the outside of the lamp body 2. A boss hole is formed in the inner side of the front center of the protruding portion 2e such that the third boss 2g for fastening is exposed to the front surface of the protruding portion 2e. The bracket 40 to which the substrate 39 is fixed is engaged with the engagement bulge portion 2b at the cut portions 39c, 40c, and is disposed on the front surface of the convex portion 2e. Next, the third fixing member 45 is inserted into the insertion hole 40h provided in the center of the flange portion 40g of the bracket 40 and fastened to the third boss 2g, whereby the bracket 40 is attached to the lamp body 2.

In assembling the vehicle lamp 1, as a step before the mounting step of the globe 4 to the lamp body 2, the power feeding portion 30 is fastened to the bracket 40 by the second fixing member 35, and then the bracket 40 to which the power feeding portion 30 is mounted to the lamp body 2 by the third fixing member 45. Similarly, as a step prior to the mounting step, the heat generating member 6 is laid on the inner surface of the globe 4, and the electrical contact 20 is provided at the distal end portion of the heat generating member 6.

Next, as a mounting step of the globe 4 to the lamp body 2, first, the seal leg 4a of the globe 4 is aligned with the seal groove 2a of the lamp body 2. As a result, the terminal 31 serving as a leaf spring terminal is held in contact with the electric contact 20 of the lamp housing 4 in a biased state, and the terminal 31 is electrically coupled to the electric contact 20. The current supplied from the vehicle battery can be supplied to the heat generating member 6 through a lead terminal, not shown, terminal 31, and electric contact 20 mounted on the connector 32 in this order.

In the mounting step, since the lamp body 2 is disposed to face the globe 4, the terminal 31 is electrically coupled to the electric contact 20 naturally by the force applied to the electric contact 20 by the terminal 31, and therefore, the assembly is easy without an electric coupling step. In addition, since the terminal 31 is electrically connected to the electric contact 20 in a state after being biased, the electric connection is stable.

When the electric contacts 20, 20 are arranged at the positions where the terminals 31, 31 face each other, the globe 4 is attached to the opening of the lamp body 2, and the terminals 31, 31 biased forward are brought into contact with the electric contacts 20, 20 to be electrically connected to the electric contacts 20, 20. In a snow melting mechanism of a vehicle lamp that continuously vibrates during running, since a heating member is provided on a lamp housing side and a power supply portion is provided on a lamp body side, the snow melting mechanism must be electrically connected across the lamp body and the lamp housing, and thus is not resistant to vibration, and there is a problem that contact failure is likely to occur due to vibration. In the vehicle lamp 1, the vibration resistance is improved by providing the electrical connection between the electrical contact 20 and the terminal 31 in the vicinity of the mounting portion of the lamp body 2 and the globe 4, which are highly rigid. The contact failure due to vibration is suppressed, and the reliability of power supply to the heat generating member 6 is improved.

Further, by attaching the substrate 39 to the lamp body 2 via the bracket 40, the substrate 39 can be arranged in consideration of the gap, arrangement, and shape with other members. Further, since the terminal 31 and the electrical contact 20 are arranged in the front-rear direction, the second fixing member 35 and the third fixing member 45 are arranged in the front-rear direction, and can be positioned and fastened with high accuracy. The flat plate portion and the flange portion 40g of the substrate 39 serving as the fastening surface can be disposed so as to be orthogonal to the front-rear direction, and is configured to resist vibration in the front-rear direction.

(Electrical contact 20)

The electrical contact 20 will be described in detail. Fig. 7 shows an electrical contact 20. Fig. 7 (a) is an enlarged view of the electrical contact 20 as seen from the lamp room S. Fig. 7 (B) is a cross-sectional view of the electrical contact 20. Fig. 9 is a diagram showing a conventional electrical contact for comparison.

The electrical contact 20 is formed by applying a conductive paste to the inner surface of the globe 4. The heat generating member 6 in the present embodiment is formed by applying a conductive paste in a predetermined pattern on the inner (back) surface of the globe 4 in a form of a drawing line in a slender manner, and the electric contact 20 is formed by applying a conductive paste similar to the conductive paste constituting the heat generating member 6 to a predetermined region of the distal end portion of the heat generating member 6.

The electrical contact 20 has a receiving member 23 for the terminal 31 to abut against as a receiving member of the terminal 31. The receiving member 23 is a circular thin plate made of metal, and is bonded by a conductive adhesive. The receiving member 23 is preferably made of a metal having high conductivity, for example, a copper alloy, and is preferably gold-plated on the surface. The receiving member 23 is a circular thin plate having a plate thickness of about 0.5mm to 2.0mm and a radius R of about 2mm to 10 mm. The conductive paste is applied to a region larger than the outer shape of the receiving member 23, and the receiving member 23 is bonded to the central surface of the region to which the conductive paste is applied.

As shown in fig. 7, the electrical contact 20 has: a pad portion 21 formed of a rectangular coated conductive paste; and a frame portion 22 having a predetermined width over the entire circumference and formed on an edge portion of the pad portion 21 so as to protrude. The frame 22 is made of the same conductive paste as the pad 21, but is higher than the pad 21, so that the boundary line 25 is visually confirmed as a difference in level from the pad 21 at the inner peripheral end of the frame 22 having a predetermined width. The receiving member 23 has an outer shape smaller than the inner region of the boundary line 25, and is disposed at substantially the center of the inner side of the frame 22.

Fig. 8 shows a process for forming the electrical contact 20. First, a conductive paste is rectangular-coated on a predetermined area of the inner surface of the globe 4 to form a pad portion 21. Next, the frame 22 is formed by further applying the same conductive paste from above the pad 21 to a constant width so as to draw the end of the pad 21 at the edge of the pad 21. Finally, the receiving member 23 is bonded to the center of the inner side of the frame 22 with a conductive adhesive. Thereby forming electrical contacts 20.

The electric contact is configured to have a large area to a certain extent, has good formability, and is easy to place the receiving member to a target position. However, if the outer shape of the electrical contact is larger than the outer shape of the receiving member by a predetermined amount or more, at this time, arrangement misalignment is likely to occur in arrangement of the receiving member by an amount equal to or more than a misalignment tolerance from the center of the pad portion that is the installation position. In contrast, in the electric contact 20, the frame portion 22 is provided as a mark, and the receiving member 23 is arranged with the boundary line 25 as a mark, whereby the arrangement deviation of the receiving member 23 is suppressed.

The above is illustrated by the figures. The electrical contact 920 shown in fig. 9 is constituted by only the land 921, and is a conventional structure without a frame, and is constituted by a square shape in which the length of one side of the land 921 is larger than the diameter D1 of the receiving member 923 in order to improve the formability.

The length of one side of the pad section 921 is set to be the same as the length of one side of the outer shape of the electrical contact 920. When the receiving member 923 is disposed in the center of the rectangular pad section 921, the gap between the receiving member 923 and the pad section 921 is a distance T1 in both the left-right direction and the up-down direction. Here, if the distance T1 is greater than or equal to a predetermined value, the receiving member 923 is not smoothly disposed at the center of the pad 921, but is disposed so as to be offset to either side (the two-dot chain line position in fig. 9).

In contrast, in the electrical contact 20 shown in fig. 7 (a), the length of one side of the land portion 21 is formed as a square larger than the diameter D of the receiving member 23, and the frame portion 22 having the width W is provided on the outer periphery of the land portion 21, so that the receiving member 23 can be arranged with respect to the boundary line 25 smaller than the outer shape of the land portion 21. When the length of one land 21 is equal to the length of one land 921, the distance T that is the gap between the receiving member 23 and the boundary line 25 is smaller than the distance T1 by the width W of the frame 22 (T1 > T) than the conventional electrical contact 120, and therefore, the displacement of the receiving member 23 can be suppressed.

(modification of electric contact)

Fig. 10 shows a modification of the electrical contact 20. The electrical contact 20A is hexagonally shaped in external configuration. The conductive paste is applied so as to form a hexagonal shape to form the land portion 21A, the outer shape of the hexagonal land portion 21A is drawn, and the same conductive paste is applied to the side edge portion of the land portion 21A with a constant width to form the frame portion 22A. The receiving member 23 is arranged inside the frame 22A with a hexagonal boundary line 25A, which is an inner edge of the frame 22A, as a mark.

The electrical contact 20B of another modification is formed in a circular shape. The conductive paste is applied so as to form a circular shape to form a pad portion 21B, the circular shape of the pad portion 21B is drawn, and the same conductive paste is applied to the side edge portion of the pad portion 21B with a constant width to form a circular frame portion 22B. The receiving member 23 is disposed inside the frame 22B with a circular boundary line 25B serving as an inner edge of the frame 22B as a mark.

Thus, the outer shape of the electrical contact 20 is not limited to a rectangle, and may be a polygon such as a hexagon or a circle, or a circle.

(second embodiment)

Fig. 11 shows a vehicle lamp 101 according to a second embodiment. The state in which the lamp housing 4 is removed (the state in which the lamp housing 4 and the lamp body 102 are opened) is shown. The lamp units Hi, lo, etc. are omitted. Fig. 11 corresponds to fig. 3. Fig. 12 is an exploded perspective view of the vehicle lamp 101. Fig. 13 is a horizontal cross-sectional view of the vehicle lamp 101 taken along line XIII-XIII in fig. 11. Fig. 13 corresponds to fig. 4.

As shown in fig. 11, the vehicle lamp 101 includes a lamp body 102 and a globe 4 as a lamp housing. The lamp body 102 is configured identically to the lamp body 2 except that the shape of the protruding portion 102e in the lamp chamber S is different from that of the protruding portion 2e in the first embodiment. Therefore, the shape of the lamp body 102 other than the convex portion 102e and the globe 4 are the same as those of the first embodiment, and therefore, the description thereof is omitted.

The vehicle lamp 101 includes a power supply portion 130 for supplying power to the electrical contact 20 provided on the inner surface of the globe 4 in the lamp chamber S of the lamp body 102.

The power feeding unit 130 includes a substrate 139, a pair of probes 131 and 131 mounted on the front surface of the substrate 139, and a connector 132 mounted on the back surface of the substrate 139.

The probe 131 is a retractable rod-shaped terminal biased by an elastic member (not shown) such as a spring, and is entirely gold-plated, with a hemispherical tip.

The power supply portion 130 is disposed in the vicinity of the engagement bulge portion 2b provided below the center among the six engagement bulge portions 2b provided at the periphery of the opening of the lamp body 102, and is directly attached to the lamp body 102 without via the bracket 40. A notch 139c is formed below the base 139 to avoid interference with the engagement bulge 2b and engage with the engagement bulge 2b.

A convex portion 102e to which the substrate 139 is fastened is formed on the bottom surface of the lamp chamber S. The third boss 102g for fastening is exposed to the front surface of the boss 102e on the inner side of the front center of the boss 102e, a boss hole is formed in the boss hole, the substrate 139 is disposed on the front surface of the boss 102e with the probe 131 facing the opening of the lamp body 102, and the second fixing member 135 is inserted into a through hole 139a provided in the substrate 139 and fastened to the third boss 102g, whereby the power supply unit 130 is mounted to the lamp body 102.

Since the electric contact 20 is provided so as to face the probe 131, when the globe 4 is attached to the front opening of the lamp body 102, the probe 131 is held in contact with the receiving member 23 in a biased state, and the probe 131 is electrically coupled to the receiving member 23. The current supplied from the vehicle battery is supplied to the heat generating member 6 through a lead terminal, not shown, attached to the connector 132, the probe 131, and the electrical contact 20 in this order.

The two protruding portions 102e are formed to be disconnected from each other so as to avoid interference with the connector 132 provided on the rear surface of the substrate 139, and a frame 2j corresponding to the outer shape of the rectangular flat substrate 139 is provided on the front surface of the protruding portion 102e, so that the substrate 139 engages with the engaging bulge 2b and is stably arranged on the front surface of the protruding portion 102e.
